Detailed Description

As shown in fig. 1 to 4, in an automatic coating system, a frame 10 is provided with a conveying unit 20 having a conveying support surface in a horizontal plane, and a guide unit 30, an automatic centering unit 40, and a painting unit 50 are sequentially provided on a conveying path of the conveying unit 20 from upstream to downstream. The non-stick pan A is transferred to the upstream section of the conveying unit 20 by a manual or mechanical hand, firstly, the non-stick pan A is guided by the guide unit 30, so that the connecting line of the projection of the center of the non-stick pan A in the plane of the conveying unit 20 and the projection of the spray nozzle of the spray painting unit 50 in the plane of the conveying unit 20 is basically parallel to the conveying direction of the conveying unit 20, then, the connecting line of the projection of the center of the non-stick pan A in the plane of the conveying unit 20 and the projection of the spray nozzle of the spray painting unit 50 in the plane of the conveying unit 20 is completely parallel to the conveying direction of the conveying unit 20 through the centering of the automatic centering unit 40, the automatic centering unit 40 and the spray painting unit 50 are arranged adjacently, the interval between the automatic centering unit 40 and the spray painting unit 50 is short, therefore, when the non-stick pan A is shaped by the automatic centering unit 40 to the position of the suction cup below the spray painting unit 50, the conveying direction of the non-stick pan A cannot be deflected, and the center of the non-stick pan A is ensured to be coincident with the center of the suction cup, thereby ensuring the uniformity of the spray from the nozzle. In the scheme, the guide unit 30, the automatic centering unit 40 and the paint spraying unit 50 are arranged on the linear conveying unit 20, so that the operation of transferring the upper piece and the lower piece among all links is omitted, a large amount of time is saved, and the production efficiency is greatly improved.

As a preferred aspect of the present invention, the conveying unit 20 includes an upstream segment conveying unit 20a and a downstream segment conveying unit 20b that are connected end to end, the multiple pulleys 22 at the downstream end of the upstream segment conveying unit 20a are located at the downstream side of the multiple pulleys 22 at the upstream end of the downstream segment conveying unit 20b, and the grooves of the multiple pulleys 22 at the downstream end of the upstream segment conveying unit 20a and the grooves of the multiple pulleys 22 at the upstream end of the downstream segment conveying unit 20b are arranged in a staggered manner. That is to say, the whole linear conveying unit 20 is in a plurality of sections, and each section of conveying unit can be driven by an independent driving mechanism, so that on one hand, sectional control can be realized, the conveying section with the non-stick pan A on the conveying section moves, and other conveying sections stop, thereby saving energy; on the other hand, when the conveyor belt 21 is damaged and needs to be replaced, only the corresponding conveyor belt 21 with shorter length needs to be replaced, and other conveyor belts 21 do not need to be replaced, so that the cost is lower. In order to achieve smooth connection between the adjacent upstream conveying units 20a and the downstream conveying units 20b, as shown in fig. 5, the multi-link pulley 22 at the downstream end of the upstream conveying unit 20a is located at the downstream side of the multi-link pulley 22 at the upstream end of the downstream conveying unit 20b, and the grooves of the multi-link pulley 22 at the downstream end of the upstream conveying unit 20a and the grooves of the multi-link pulley 22 at the upstream end of the downstream conveying unit 20b are arranged in a staggered manner, so that when the non-stick pan a is conveyed on the upstream conveying unit 20a, the tail end of the non-stick pan a which is not separated from the upstream conveying unit 20a is counted to the front end of the downstream conveying unit 20b, thereby preventing the non-stick pan a from overturning and ensuring smooth conveying of the non-stick pan a.

In order to further improve the smooth connection between the adjacent upstream conveying unit 20a and the downstream conveying unit 20b, projections of the downstream section of the upstream conveying unit 20a and the upstream section of the downstream conveying unit 20b in the horizontal plane, which are arranged in a connected manner, have an overlapped section, the belt surface of the conveying belt 21 at the connection position has a horizontal equal-height transition, no high-position drop exists when the non-stick pan a is conveyed to the connection position, the transition is stable, and the motor 23 drives the multiple belt pulley 22 to rotate to drive the conveying belt 21 to move.

Because only two ends of the V-belt are provided with the multi-link belt wheels 22, and the length of the V-belt is longer, if a supporting mechanism is not arranged in the middle, a pocket-beating phenomenon may occur, so that the supporting rails 24 are arranged on the upper table top of the rack 10 below each V-belt, the length direction of the supporting rails 24 is consistent with that of the V-belt, two ends of the supporting rails 24 extend to the positions near the multi-link belt wheels 22 at the two ends, clamping grooves for clamping the V-belts are formed in the surfaces of the supporting rails 24, the surface height of the supporting rails 24 is equal to that of the multi-link belt wheels 22, the upper surface of the conveying belt 21 is always in the same horizontal plane, and the conveying stability of the non-stick pan A is guaranteed.

As shown in fig. 6, the guiding unit 30 includes guiding plates 31 respectively disposed at two sides of the conveying unit 20, the distance between the guiding plates 31 at two sides is gradually decreased from the top to the bottom, and the rear end distance is greater than the diameter of the non-stick pan a, so that the conveying smoothness of the non-stick pan a is not affected while guiding the non-stick pan a, the front end of the guiding plate 31 is hinged to the frame 10, the hinge shaft 33 is disposed in the vertical direction, and the guiding plate 31 rotates around the hinge shaft 33 to adjust the rear end distance of the guiding plate 31, so as to adapt to non-stick pans a with different sizes.

A connecting plate 32 extends outwards from the rear end of the guide plate 31, an arc hole 32a is formed in the connecting plate 32, the curvature center of the arc hole 32a is overlapped with the axis center of the hinge shaft 33, and a locking member 34 penetrates through the arc hole 32a to fixedly connect the connecting plate 32 with the rack 10. Generally, a positioning column is arranged on the frame 10, the positioning column passes through the arc-shaped hole 32a, when the guide plate 31 rotates around the hinge shaft 33, the positioning column always slides in the arc-shaped hole 32a, the rotating stability of the guide plate 31 is ensured, and after the guide plate is adjusted, the guide plate is locked by a locking part 34; the positioning column can also be directly arranged on the locking part 34, and the locking part 34 is in rotating fit with the frame 10, so that the locking part 34 can be prevented from falling and shifting.

In order to prevent the outer wall of the non-stick pan A from being scratched, guide wheels 35 are arranged on the guide plate 31 in an arrayed mode, wheel cores of the guide wheels 35 are arranged in the vertical direction, the guide wheels 35 protrude out of the inner side plate surface of the guide plate 31 and guide the non-stick pan A, and the outer wall of the non-stick pan A is ensured to be in contact with the guide wheels 35 so as to achieve rolling guide.

As shown in fig. 7, the automatic centering unit 40 includes air cylinders 41 disposed on the frames 10 at both sides of the conveying unit 20, the air cylinders 41 drive the non-stick pan a to move until the non-stick pan a coincides with the center of the suction cup 51 of the downstream paint spraying unit 50, and the positioning accuracy of the air cylinders 41 is high.

As shown in fig. 8, the paint spraying unit 50 includes an outer shaft tube 52, a tube core direction of the outer shaft tube 52 is located in the vertical direction, the upper portion of the outer shaft tube 52 forms a rotation fit with a bearing 53 arranged in the through hole, the outer wall of the lower portion of the outer shaft tube 52 is connected with a chain wheel 54 key through a key slot, an inner shaft tube 55 is arranged in a tube cavity of the outer shaft tube 52, a long key on the outer wall of the inner shaft tube 55 is arranged in the key slot on the inner wall of the outer shaft tube 52 to form an axial sliding and circumferential limit fit, the length direction of the long key is consistent with the vertical direction, a suction cup 51 is arranged at the upper end of the inner shaft tube 55, the lower end is connected with a vacuum source through a rotary joint 56, and the lower end of the outer shaft tube 52 is connected with a lifting cylinder 58. In the structure, the inner shaft tube 55 can do linear motion in the vertical direction along the key groove, because the heights of the non-stick pans A with different specifications are different, in order to adapt to the height of the nozzle of the paint spray booth 57, the height of the sucking disc 51 is properly adjusted, namely the height of the upper opening edge of the non-stick pan A is adjusted to adapt to the height of the nozzle, so that the spraying quality is ensured; meanwhile, the inner shaft tube 55 can synchronously rotate along with the outer shaft tube 52, the non-stick pan A continuously rotates in the spraying process, the spraying uniformity of the whole non-stick pan A is ensured, and the product quality is ensured.

Further, a paint spray booth 57 is provided above the suction cup 51 at a distance, the spray direction of the nozzles in the paint spray booth 57 is arranged downward, and the center line of the nozzles coincides with the center line of the suction cup 51. After the automatic positioning liner 40 is positioned, the center line of the non-stick pan A is superposed with the center line of the sucker 51, and the center line of the nozzle is superposed with the center line of the sucker 51, so that the center line of the non-stick pan A is superposed with the center line of the nozzle, the paint spraying is uniform, and the product quality is good.

Because the inner paint comprises three layers of primer, intermediate paint and finish paint, a plurality of groups of paint spraying assemblies formed by the automatic centering units 40 and the paint spraying units 50 are arranged at intervals in the transmission direction of the conveying unit 20, so that on the same production line, the spraying operation of three layers of the primer, the intermediate paint and the finish paint can be realized on the premise that the non-stick pan A does not fall off, two non-stick pans A can be sprayed in sequence on each group of two automatic centering units 40 and two paint spraying units 50, the production efficiency is improved, because the conveying belt 21 is conveyed forwards all the time, when the positions of the automatic centering mechanisms 40 and the paint spraying mechanisms 50 are reached, the non-stick pans A need to stop to perform the positioning and paint spraying operation, and the blocking units 70 are further arranged on the rack 10 at the downstream position close to the automatic centering mechanisms 40 and the paint spraying mechanisms 50.

When the driving mechanism drives the blocking unit 70 to do lifting motion in the vertical direction, the conveying of the non-stick pan A is blocked or avoided, when the non-stick pan A needs to be stopped, the driving mechanism drives the blocking unit 70 to move to the upper position to block the non-stick pan A, after centering/spraying is finished, the driving mechanism drives the blocking unit 70 to move to the lower position, and the non-stick pan A is continuously conveyed to the downstream.
