The structure of the camera glass splinting jig provided by the preferred embodiment of the invention is described in detail below with reference to fig. 1-5.

The camera glass lobe of a leaf tool that this embodiment provided includes base 1 and lobe of a leaf piece 2 that the components of a whole that can function independently set up.

As shown in fig. 1, 2 and 4 in particular, the base 1 is a substantially flat rectangular parallelepiped structure. The upper surface of which is partially recessed to form a cavity 102 for receiving the rupture disc element 2. The mold cavity 102 is substantially rectangular in shape and conforms to the configuration of the lobe member 2. The base 1 at the two ends of the cavity 102 is provided with a plurality of clearance spaces 104 for taking out or placing the split piece 2.

The cavity 102 has a negative pressure groove 103 in the bottom surface thereof, and in the present embodiment, the negative pressure groove 103 is substantially distributed in a shape of a Chinese character 'tian'.

The side surface of the base 1 is provided with an air exhaust hole 101, and the air exhaust hole 101 penetrates through the side surface of the base 1 and is communicated to the negative pressure groove 103.

The splinter element 2 is of a substantially flat cuboid structure, the majority of the area of its upper surface being a splinter zone, the splinter zone being rectangular and substantially the same shape as the glass sheet to be splinted. A plurality of splinter grooves 201 are arranged in the splinter area, and the number and the positions of the splinter grooves 201 are corresponding to the number and the positions of the glass monomers 3 distributed on the glass sheet to be splintered. The shape of the splinter groove 201 is the same as that of the glass monomer 3, and the size of the splinter groove is slightly larger than that of the glass monomer 3, so that the number of the splinter grooves 201 on the surface of the splinter piece 2 can be effectively increased, the position of the glass monomer 3 after splinter can be ensured to be stable, the position change of the glass monomer 3 in the operation process is prevented, and the operation precision is improved. For example, in the present embodiment, the shape of the cleavage recess 201 is an ellipse. The depth of the splinter groove 201 is the same as the thickness of the glass monolith 3.

The bottom of each lobe groove 201 is provided with a negative pressure hole 202, and the negative pressure hole 202 penetrates through the lobe member 2 along the depth direction of the lobe member 2. The negative pressure hole 202 is located in the middle of the lobe groove 201. When the splinter member 2 is disposed in the cavity 102 of the base 1, the negative pressure hole 202 communicates with the negative pressure groove 103.

The splitting piece 2 is further provided with a plurality of positioning buckles 203, specifically, as shown in fig. 1, 3, 4 and 5, the positioning buckles 203 are distributed on the peripheral edge of the splitting area, two sides in the length direction of the splitting area are respectively provided with 3 positioning buckles 203, and two sides in the width direction of the splitting area are respectively provided with 2 positioning buckles 203. Correspondingly, a plurality of positioning grooves 402 are also arranged on the periphery of the glass sheet with the splinters, 3 positioning grooves 402 are respectively arranged on two sides of the glass sheet in the length direction, and 2 positioning grooves 402 are respectively arranged on two sides of the glass sheet in the width direction. When the glass sheet is arranged in the splitting area, the positioning buckle 203 is matched with the positioning groove 402 to position the glass sheet in the splitting area.

The following describes the splitting process provided by the present invention in detail with reference to the above-mentioned camera glass splitting jig.

First, the suction holes 101 on the side of the base 1 are communicated with an external vacuum extractor.

Then, the glass sheet to be split is placed in the splitting area on the surface of the splitting piece 2, and the glass sheet is positioned in the splitting area through the positioning buckle 203 on the surface of the splitting piece 2 and the positioning groove 402 on the side surface of the glass sheet. At this time, the glass sheet entirely covers the breaking groove 201, the upper opening of the breaking groove 201 is closed, and the plurality of glass monomers 3 to be broken on the glass sheet are respectively positioned right above the plurality of breaking grooves 201 on the surface of the breaking piece 2.

And then starting the vacuum pumping device to form negative pressure in the splinter groove 201 through the suction hole 101, the negative pressure groove 103 and the negative pressure hole 202. On the one hand, as is well known to those skilled in the art, the glass sheet to be split is subjected to laser cutting treatment, and the glass monomer 3 can be split from the glass sheet only with small force; on the other hand, the glass sheet covers the splinter groove 201, a relatively closed space is formed in the splinter groove 201, and a relatively large negative pressure suction force can be formed in the splinter groove 201 through the air exhaust treatment of the vacuum pumping device, so that the glass monomer 3 is smoothly split from the glass sheet and falls into the splinter groove 201. The specific negative pressure can be adjusted by adjusting the power of the vacuum-pumping device, and generally speaking, the function of the invention can be realized by the conventional vacuum-pumping device.

By the above-mentioned evacuation process, the glass element 3 is broken apart from the glass sheet and falls into the break groove 201. At this time, the glass sheet has the glass frame 4 left and the glass hole 401 is formed at the position where the raw glass element 3 is located. The glass frame 4 is removed from the surface of the cleavage piece 2. Because the glass monomer 3 that splits all falls into splitting recess 201, need not to arrange its position in order again.

Then, a protective film is pasted on the surface of the splinter piece 2, so that the glass monomer 3 is pasted and adhered on the protective film (as is well known, the protective film adopted in the field has self-absorption viscosity, covers the glass monomer 3 with a smooth surface, and can be adhered into a whole); and stopping the air exhaust treatment, and taking the protective film and the plurality of glass monomers 3 obtained by splitting off from the surface of the splitting piece 2, thereby completing the splitting operation of the invention. In general, after the protective film is removed together with the glass element 3, the other surface of the glass element 3 may be covered with the protective film.

The splitting process disclosed by the invention is simple to operate, a large number of glass monomers 3 can be split at one time, and the glass monomers 3 do not need to be arranged after being split, so that the production efficiency is greatly improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
