When in work, the whole automatic production line is controlled by the intelligent control terminal to automatically run, the mechanical arm puts the silica gel blank into the middle position of the conveyor belt on the workbench, and the interval between the adjacent silica gel blanks on the conveyor belt is kept consistent, then the silica gel blanks move along with the started conveyor belt, when the silica gel blank moves to a position close to the material changing module, the intelligent control terminal controls the conveyor belt to stop moving, the rotating arm on the material changing module rotates under the control of the intelligent control terminal to drive the material changing block on the rotating arm to move to the position above the silica gel blank, then the second telescopic rod connected with the material changing block moves to drive the sucker on the material changing block to be in close contact with the silica gel blank, when the fan is started, the fan in the fan rotates forwards to draw out air in a gap between the end part of the sucking disc and the silica gel blank, so that the silica gel blank is tightly contacted with the sucking disc and is fixed; then the rotating arm rotates to enable the material changing block to rotate to the position above a processing groove in the hot pressing groove, and the second telescopic rod moves downwards to enable the silica gel blank to be in contact with the middle of the processing groove; the fan in the fan rotates reversely, the silica gel blank is separated from the sucker under the action of airflow, and then the rotating arm resets; the intelligent control terminal controls the hot press to start, so that an upper cover plate of the hot press moves downwards to be combined with the processing groove, the heater on the hot press is started, the silica gel blank in the processing groove is deformed under the hot pressing action and is processed into a silica gel sheet which is adaptive to the shape of the processing groove under the limiting action of the processing groove, and meanwhile, a part of silica gel material is melted under the hot pressing action and flows into a gap between the lower surface of the upper cover plate and the lower surface of the hot pressing groove, which is close to the processing groove, so as to form a boundary skin; after the silica gel sheet is machined and formed, the upper cover plate moves upwards to expose the silica gel sheet, the intelligent control terminal controls the rotating arm to rotate, so that the sucker on the material changing block is in close contact with the surface of the silica gel sheet, and the fan is controlled to rotate forwards again to enable the silica gel sheet to be in close contact with the sucker under the action of negative pressure and to be separated from the machining groove; moreover, because the boundary skin and the part of the lower surface of the hot-pressing groove close to the processing groove have a sticking phenomenon under the hot-pressing action, the boundary skin and the part are combined tightly, and the separation of the silica gel sheet is hindered; therefore, when the silica gel sheet is separated, the intelligent control terminal controls the first telescopic rod to be started to push the top block in the first groove to move upwards, and because the first groove is close to the edge part of the processing groove, the produced flaw-piece covers the upper surface of the top block; the silica gel piece moves to the conveyer belt again under the effect of rotor arm and moves to shearing unit and cuts off the flaw-piece under the effect of conveyer belt, receives drying process in the drying unit afterwards, combines together with the circuit component of heating on the assembly unit, at last in the detection of detecting element acceptance quality, carries out packaging process after detecting qualified, and whole course of working is automatic going on under the effect at intelligent control terminal, has saved the manpower, has improved machining efficiency.

Preferably, a first cavity is formed in the top block; an air guide groove is formed in the upper surface of the ejector block, which is far away from the processing groove, and communicated with the first cavity; a first air hole is formed in the position, opposite to the machining groove, of the side face of the top block, and the first air hole is communicated with the inside of the first cavity; and air guide pipes are uniformly arranged on the side surface of the material changing block and the part, corresponding to the air guide groove on the top block, of the material changing block, and the air guide pipes are communicated with the inside of the fan.

When the device works, after a silica gel sheet is subjected to hot-press forming, the end part of the first telescopic rod pushes the ejector block to extend out and eject the flaw-piece, then the material changing block moves downwards to be in contact with the surface of the silica gel sheet, and the end part of the air guide tube arranged at the corresponding position on the side surface of the material changing block extends into the air guide groove on the upper surface of the ejector block; the intelligent control terminal controls the fan to start, the fan pumps air in the sucker out and sends the air into the air guide tube, the air flows into the first cavity along the air guide tube and the air guide groove, and the air is sprayed out from the first air hole in the side wall of the first cavity; because the upper surface of the ejector block jacks up the flaw-piece and the first air hole is positioned at the position of the side surface of the ejector block, which is opposite to the processing groove, the air sprayed by the first air hole flows into the gap between the flaw-piece and the surface of the processing groove, and the lower surfaces of the flaw-piece and the silicon sheet are separated from the lower surfaces of the processing groove and the hot pressing groove at an accelerated speed under the impact of air flow, so that the separation of the silicon sheet is smoother, and the processing efficiency of the silicon heating sheet is improved; meanwhile, the phenomenon that the formed silica gel sheet deforms due to the dragging effect caused by the adhesion of the flaw-piece and the lower surface of the hot pressing groove, and the forming quality of the silica gel sheet is influenced is avoided.

Preferably, the first groove extends towards the direction far away from the processing groove and extends into the part of the upper surface of the hot pressing table, which is positioned outside the hot pressing groove, the air guide groove is positioned at the part of the upper surface of the top block, which extends into the upper surface of the hot pressing table, and the side part of the top block, which is back to the processing groove, is an inclined plane.

When the silicon rubber sheet forming device works, in order to avoid the phenomenon that the boundary leather covering the upper surface of the ejector block obstructs the combination of the air guide pipe and the air guide groove, the first groove extends to the position outside the hot pressing groove, the air guide groove on the ejector block is positioned outside the hot pressing groove, and the boundary leather generated in the silicon rubber sheet forming process cannot extend into the position outside the hot pressing groove under the limiting action of the side surface of the hot pressing groove, so that the boundary leather cannot obstruct the combination of the air guide pipe and the air guide groove; and because the position that the kicking block stretches out back and a groove lateral wall contact is the inclined plane for at the end of the reloading process, a telescopic link drives the kicking block and resets the in-process, makes the kicking block get back to a groove smoothly through the inclined plane effect.

When the pneumatic edge separation device works, after the end part of the air guide pipe is combined with the air guide groove, air sprayed out of the air guide pipe impacts the air guide groove, on one hand, the air flows into the first cavity along the air guide groove, and is sprayed out of the first air hole to impact the lower surface of the edge, so that the separation of the edge is accelerated; on the other hand, the inner surface of the cavity I drives the part, which is positioned on one side of the rotating shaft and close to the air guide pipe, on the ejector block to rotate downwards under the impact of air, and meanwhile, the part, which is positioned on one side of the rotating shaft and close to the processing groove, on the ejector block is tilted upwards, so that the contacted edge skin is further subjected to an upward pulling force and is separated from the surface of the hot pressing groove at an accelerated speed, and the silica gel sheet is separated from the hot pressing machine more smoothly; then, the part of the top block, which is close to the air guide groove, rotates downwards, so that the air guide groove is separated from the air guide pipe, the air guide pipe cannot normally and continuously supply air to the air guide groove, and the top block is not pressed any more and is reset under the action of a connected spring; and because the part of the top block contacting with the side wall of the first groove after extending out is an inclined surface, along with the extension of the top block, the clearance between the inclined surface part of the top block and the opposite side surface of the first groove is increased, and the obstruction of the side surface of the first groove to the rotation of the top block when the top block rotates is reduced.

Preferably, the end part of the top block close to the processing tank is conical, and the conical end part is subjected to fillet treatment.

When the processing tank is in work, when the end part of the ejector block close to the processing tank is tilted upwards, the end part of the ejector block close to the processing tank is conical, and the stress on the contacted edge skin is concentrated, so that the friction force applied to the edge skin is increased, the pulling force applied to the edge skin is increased, and the edge skin is accelerated to separate from the processing tank; and the conical end part of the top block is processed through a fillet, so that the phenomenon that the end part of the top block is too sharp to pierce a boundary skin and to separate the silica gel sheet is avoided.

Preferably, the side face, close to the adjacent first groove, of the ejector block is uniformly provided with a second air hole, the second air hole points to the direction close to the upper surface of the ejector block in an inclined mode, and the second air hole is communicated with the inside of the second groove.

During operation, because the side that is close to a groove on the kicking block is mutually perpendicular with the upper surface of kicking block, consequently, after the air in the air duct spouts into a chamber, some air is spout from No. two gas pockets, and No. two gas pockets to the direction slope that is close to the kicking block upper surface, make No. two gas pockets in the spun air impact the kerchief position between the adjacent kicking block, make the kerchief position that contacts with the kicking block upper surface receive the ascending impact force of slope, accelerate the separation of kicking block upper surface and kerchief, thereby accelerate the separation of kerchief and kicking block, make the silica gel piece break away from the hot press more smoothly.

The invention has the following beneficial effects:

1. according to the continuous automatic production line for the silica gel heating sheet, the first telescopic rod is controlled to be started through the intelligent control terminal, the top block in the first groove is pushed to move upwards, so that the flaw-piece is pressed to slide on the upper surface of the top block and is separated from the part attached to the lower surface of the hot pressing groove, the separation of the flaw-piece and the surface of the hot pressing groove is accelerated, the obstruction caused when the silica gel sheet is separated is reduced, the silica gel sheet is separated more smoothly, the labor is saved, and the processing efficiency is improved.

2. According to the continuous automatic production line for the silica gel heating sheet, air in the sucker is pumped out through the fan and is sent into the air guide pipe, so that air sprayed out of the air hole I flows into a gap between the flaw-piece and the surface of the processing groove, and under the impact of airflow, the lower surfaces of the flaw-piece and the silica gel sheet are accelerated to be separated from the lower surfaces of the processing groove and the hot pressing groove, so that the separation of the silica gel sheet is smoother, and the processing efficiency of the silica gel heating sheet is improved; meanwhile, the phenomenon that the formed silica gel sheet deforms due to the dragging effect caused by the adhesion of the flaw-piece and the lower surface of the hot pressing groove, and the forming quality of the silica gel sheet is influenced is avoided.

In operation, in order to avoid the boundary leather covering the upper surface of the top block 18 from obstructing the combination of the air duct 431 and the air guide groove 182, the first groove 17 extends to the position outside the hot pressing groove 15, the air guide groove 182 on the top block 18 is positioned at the position outside the hot pressing groove 15, and the boundary leather generated in the silicone sheet molding process cannot extend into the position outside the hot pressing groove 15 due to the limiting effect of the side surface of the hot pressing groove 15, so the boundary leather cannot be obstructed in the combination process of the air duct 431 and the air guide groove 182; and because the position that the kicking block 18 stretches out back and contacts with a groove 17 lateral wall is the inclined plane for at the end of the reloading process, telescopic link 181 drives kicking block 18 and resets the in-process, makes kicking block 18 get back to a groove 17 smoothly through the inclined plane effect.

As a specific embodiment of the present invention, the end of the first telescopic link 181 is rotatably connected with a rotating shaft 184, the rotating shaft 184 is fixedly connected with the middle portion of the lower surface of the top block 18, and a return spring is fixedly connected between the outer surface of the end of the telescopic link and the lower surface of the top block 18.

During operation, after the end of the air duct 431 is combined with the air guide groove 182, after the air duct 431 sprays air to impact the air guide groove 182, on one hand, the air flows into the first cavity 19 along the air guide groove 182 and sprays air from the first air hole 183 to impact the lower surface of the edge leather, and the separation of the edge leather is accelerated; on the other hand, the inner surface of the first cavity 19 drives the part of the top block 18, which is located on the side of the rotating shaft 184 close to the air duct 431, to rotate downwards under the impact of air, and the part of the top block 18, which is located on the side of the rotating shaft 184 close to the processing groove 16, tilts upwards, so that the contacted edge skin further receives an upward pulling force and is separated from the surface of the hot pressing groove 15 in an accelerating manner, and the silica gel sheet is separated from the hot press 1 more smoothly; then, as the part of the top block 18 close to the air guide groove 182 rotates downwards, the air guide groove 182 is separated from the air guide tube 431, the air guide tube 431 cannot normally supply air to the air guide groove 182 continuously, and the top block 18 is not pressed any more and is reset under the action of the connected spring; and because the part of the top block 18 contacting with the side wall of the first groove 17 after extending out is an inclined surface, along with the extension of the top block 18, the clearance between the inclined surface part of the top block 18 and the opposite side surface of the first groove 17 is increased, and the obstruction of the side surface of the first groove 17 to the rotation of the top block 18 when the top block 18 rotates is reduced.

In an embodiment of the present invention, the end of the top block 18 near the processing tank 16 is tapered, and the tapered end is rounded.

When the processing tank 16 is in work, when the end part of the top block 18 close to the processing tank 16 is tilted upwards, the end part of the top block 18 close to the processing tank 16 is conical, and the stress on the contacted edge skin is concentrated, so that the friction force applied to the edge skin is increased, the pulling force applied to the edge skin is increased, and the edge skin is accelerated to be separated from the processing tank 16; and the conical end part of the top block 18 is processed by a fillet, so that the phenomenon that the end part of the top block 18 is too sharp to pierce a boundary skin and obstruct the separation of the silica gel sheet is avoided.

In an embodiment of the present invention, the top block 18 is uniformly provided with a second air hole 185 on a side surface close to the adjacent first groove 17, the second air hole 185 is obliquely directed to a direction close to the upper surface of the top block 18, and the second air hole 185 is communicated with the inside of the second groove 182.

During operation, because the side surface of the top block 18 close to the first groove 17 is perpendicular to the upper surface of the top block 18, after the air in the air duct 431 is sprayed into the first cavity 19, a part of air is sprayed out of the second air hole 185, and the second air hole 185 inclines towards the direction close to the upper surface of the top block 18, so that the air sprayed out of the second air hole 185 impacts the edge skin part between the adjacent top blocks 18, the edge skin part in contact with the upper surface of the top block 18 is subjected to the upward inclined impact force, the separation of the upper surface of the top block 18 and the edge skin is accelerated, the separation of the edge skin and the top block 18 is accelerated, and the separation of the silica gel sheet from the hot press 1 is smoother.

The specific working process is as follows:

when the automatic production line works, the whole automatic production line is controlled by the intelligent control terminal to automatically operate, silica gel blanks are placed in the middle position of the conveyor belt 3 on the workbench 2 by the manipulator, the intervals between the adjacent silica gel blanks on the conveyor belt 3 are kept consistent, then the silica gel blanks move along with the conveyor belt 3 after being started, when the silica gel blanks move to the position close to the material changing module 4, the intelligent control terminal controls the conveyor belt 3 to stop moving, the rotating arm 42 on the material changing module 4 rotates under the control of the intelligent control terminal to drive the material changing block 43 on the rotating arm 42 to move to the position above the silica gel blanks, and then the second telescopic rod 421 connected with the material changing block 43 moves to drive the suction cup 44 on the material changing block 43 to be in close contact with the silica gel blanks; then the rotating arm 42 rotates 180 degrees, so that the changing block 43 rotates to the position above the processing groove 16 in the hot pressing groove 15, and the second telescopic rod 421 moves downwards to make the silica gel blank contact with the middle part of the processing groove 16; after the silicone sheet is formed, the upper cover plate 13 moves upwards to expose the silicone sheet, the intelligent control terminal controls the rotating arm 42 to rotate, so that the suction cup 44 on the material changing block 43 is in close contact with the surface of the silicone sheet, and the intelligent control terminal controls the first telescopic rod 181 to start to push the top block 18 in the first groove 17 to move upwards, so that the flaw-piece is pressed on the upper surface of the top block 18 to slide and is separated from the part adhered to the lower surface of the hot pressing groove 15; the silica gel sheet moves to the conveyor belt 3 again under the action of the rotating arm 42 and moves to the shearing unit under the action of the conveyor belt 3 to cut off the flaw-piece, then is dried in the drying unit and is combined with the heated circuit element on the assembling unit, finally, the acceptance performance of the detection unit is detected, and the packing treatment is carried out after the acceptance performance of the detection unit is detected; after the silica gel sheet is hot-pressed and hot-pressed to be molded, the end part of the first telescopic rod 181 pushes the top block 18 to extend out and push out the edge skin, then the material changing block 43 moves downwards to be contacted with the surface of the silica gel sheet, and the end part of the air guide tube 431 arranged at the corresponding position on the side surface of the material changing block 43 extends into the air guide groove 182 on the upper surface of the top block 18; the intelligent control terminal controls the fan 45 to start, the fan 45 pumps air in the sucker 44 out and sends the air into the air duct 431, the air flows into the first cavity 19 along the air duct 431 and the air guide groove 182, and the air is sprayed out from the first air hole 183 on the side wall of the first cavity 19; because the top surface of the top block 18 jacks up the flaw-piece and the first air hole 183 is positioned at the position of the side surface of the top block 18 facing the processing tank 16, the air jetted by the first air hole 183 flows into the gap between the flaw-piece and the silicon sheet and the surface of the processing tank 16, so that the flaw-piece and the silicon sheet are separated from the lower surfaces of the processing tank 16 and the hot pressing tank 15 in an accelerated way.
