Description

Technical Field

[0001] This invention belongs to the technical field of long prism production equipment, and specifically relates to a double-sided polishing device and process for bonding glass substrates to long prisms. Background Technology

[0002] In the production and polishing of long prisms, the long prism is usually placed in a fixture first, and then cut into individual particles by laser cutting equipment. The individual particles are then glued and placed on a plate. The first side of the individual particle is then polished by a single-sided adjustment polishing machine. After the first side is polished, the glue is removed, and the same method is used to place the particle on the plate to polish the other side. In this process, the individual particle needs to be moved up and down the plate twice, and it is necessary to ensure that each particle is 100% turned over.

[0003] as follows Figure 12 As shown, in the polishing of triangular prisms, the cut triangular prism particles are first glued one by one onto a rectangular material plate, and then the rectangular material plate is placed into a polishing disc for polishing. After single-sided polishing, the glue is removed and the disc is reloaded to polish the other side. This method of processing long prisms involves cumbersome loading and unloading, which reduces the production efficiency of long prisms. Therefore, we need to propose a double-sided polishing device and process for long strip prisms with bonded glass substrates to solve the above-mentioned problems, so as to effectively reduce the number of loading and unloading operations and improve the production efficiency of long prisms. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a double-sided polishing device for bonding long strip prisms to glass substrates, comprising a base with a collection groove on the base, a lower grinding disc installed inside the collection groove, the lower grinding disc being driven by a first driving mechanism, a bracket fixed to one side of the base located in the collection groove, a fixed seat mounted on the upper end of the bracket via a first electric push rod, an upper grinding disc mounted on the lower end of the fixed seat, the upper grinding disc being driven by a second driving mechanism installed inside the fixed seat, and a clamping mechanism for clamping material disposed below the upper grinding disc, the clamping material being composed of a strip-shaped glass substrate to which multiple triangular prisms are bonded, and the two ends of the clamping mechanism being connected to the upper surface of the base via a lifting mechanism;

[0005] The clamping mechanism includes two clamping blocks, each with a material feeding groove for placing clamped material. One of the clamping blocks is equipped with a limiting mechanism for restricting the polishing depth of the clamped material. The other clamping block has a cavity inside for the limiting mechanism to be installed. One side of the fixing seat is fixed with an abutment rod for one end of the limiting mechanism to abut against. The four corners of the collection groove are each equipped with a nozzle for spraying polishing fluid. The inside of the collection groove is connected to a drain pipe.

[0006] Furthermore, the lifting mechanism includes a second electric push rod and a support block installed at the piston rod end of the second electric push rod. A third electric push rod is installed on one side of the support block, and the clamping block is installed at the piston rod end of the third electric push rod. The support block and the clamping block are connected by two telescopic rods.

[0007] Furthermore, each of the clamping blocks has multiple equidistant feeding slots, and a limit rod is movably inserted into the upper end of the clamping block. The upper end of the clamping block has a limit hole for the limit rod to be inserted. When there is material in the feeding slot, after the limit rod is inserted, the lower surface of the limit rod abuts against the upper surface of the material.

[0008] Furthermore, the limiting mechanism includes a bidirectional screw rotatably installed inside one of the clamping blocks. The two ends of the bidirectional screw are threadedly connected to moving blocks. A limiting rod is fixed to one side of the moving block. One end of the limiting rod passes through one side of the clamping block and extends to the outside. An elastic limiting member is sleeved on the clamping block outside the limiting rod. One end of the elastic limiting member is fixed to one side of the clamping block. The distance between the two limiting rods is adjusted by an adjusting mechanism.

[0009] Furthermore, the adjustment mechanism includes a rotating shaft rotatably connected to one side of the chamber. One end of the rotating shaft and the middle of the bidirectional screw are both equipped with bevel gears, and the two bevel gears mesh. An adjustment disk is installed at the other end of the rotating shaft, and an adjustment rod is slidably connected to the adjustment disk. The clamping block has positioning holes arranged in a ring array on the side where the adjustment disk is installed, allowing one end of the adjustment rod to be slidably inserted.

[0010] Furthermore, the elastic limiting member includes a stop block and a spring. One end of the spring is fixed to the upper surface of the clamping plate, and the other end of the spring is fixed to the stop block. There is a gap between the stop block and the limiting rod.

[0011] Furthermore, the abutment rod is L-shaped, with one end fixed to the outer wall of the fixed base, and the other end of the abutment rod having a clearance hole for the stop block to enter.

[0012] Furthermore, the first driving mechanism includes a first motor and a rotating shaft rotatably connected to the center of the collection tank. The first motor is installed at the lower end of the base, and support feet are provided at the four corners of the lower surface of the base. One end of the rotating shaft is connected to the output shaft of the first motor, and the other end of the rotating shaft is fixed to the lower surface of the lower grinding disc.

[0013] Furthermore, the second drive mechanism includes a second motor installed inside the fixed base, the output shaft of the second motor passing through one side of the fixed base and fixed to the upper grinding disc, and the output shaft of the second motor being rotatably connected to the fixed base via a coupling.

[0014] Based on the above-described apparatus for double-sided polishing of elongated prisms for bonding glass substrates, this invention also provides a process for double-sided polishing of elongated prisms for bonding glass substrates, comprising the following steps:

[0015] S1. Bond multiple prism strips onto a 4-5mm thick glass substrate to obtain the product to be processed;

[0016] S2. Use laser cutting to cut the glass substrate and prism strip together to obtain a strip-shaped product;

[0017] S3. Install multiple strip-shaped products on the clamping mechanism in pairs back to back, and then use the lifting mechanism to drive the strip-shaped products to contact the lower grinding disc. Then move the upper grinding disc to contact the strip-shaped products for double-sided polishing.

[0018] S4. Adjust the limiting distance of the limiting mechanism to limit the polishing depth of the strip product until the prism polishing is completed before performing the degumming operation.

[0019] The beneficial effects of this invention are:

[0020] 1. This invention, through the cooperation of an upper grinding disc, a lower grinding disc, a clamping mechanism, and a lifting mechanism, firstly bonds the prism strip to a 4-5mm thick substrate glass during prism polishing. Then, laser cutting is used to cut the glass and the prism strip together. The cut prism strip is then polished using a double-sided polishing process. The cut prism strip is placed in the clamping mechanism and polished using a high-precision double-sided flat polishing machine. This increases production efficiency by at least 100%, saves more than 50% of production personnel, and ensures that 100% of the prism particles are polished by the double-sided polishing process, thus improving the polishing efficiency of the prism.

[0021] 2. The present invention, through the cooperation of the limiting mechanism and the clamping mechanism, can effectively adjust the polishing depth of the clamped material according to the polishing requirements, thereby reducing the phenomenon of over-polishing of the clamped material.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides a double-sided polishing device for bonding long strip prisms to glass substrates, such as... Figure 1-11 As shown, the system includes a base 1 with a collection groove 3. A lower grinding disc 4 is installed inside the collection groove 3 and is driven by a first driving mechanism. A bracket 10 is fixed to one side of the base 1 in the collection groove 3. A fixed seat 8 is installed at the upper end of the bracket 10 via a first electric push rod 9. An upper grinding disc 7 is installed at the lower end of the fixed seat 8 and is driven by a second driving mechanism installed inside the fixed seat 8. A clamping mechanism 5 for clamping a material 6 is provided below the upper grinding disc 7. The material 6 is composed of a strip-shaped glass substrate 61 with multiple triangular prisms 62 bonded to it. The two ends of the clamping mechanism 5 are connected to the upper surface of the base 1 via a lifting mechanism 2.

[0039] like Figure 4As shown, the clamping mechanism 5 includes two clamping blocks 51. Each clamping block 51 has a material feeding groove 53 for placing the clamped material 6. One of the clamping blocks 51 is provided with a limiting mechanism 15 for limiting the polishing depth of the clamped material 6. One of the clamping blocks 51 has a cavity inside for the limiting mechanism 15 to be installed. One side of the fixing seat 8 is fixed with an abutting rod 11 for one end of the limiting mechanism 15 to abut against. Each of the four corners of the collecting tank 3 is equipped with a nozzle 14 for spraying polishing fluid. The inside of the collecting tank 3 is connected to a drain pipe 12.

[0040] During prism polishing, the prism strip is first bonded to a 4-5mm thick substrate glass. Figure 10 As shown, the glass and prism strip are then cut together using laser cutting. The cut prism strip is then polished on both sides. The cut prism strip is placed in the clamping mechanism 5 and polished using a high-precision double-sided flat polishing machine. This increases production efficiency by at least 100% and saves more than 50% of production personnel. Furthermore, the double-sided polishing process ensures that 100% of the prism particles are polished, thus improving the polishing efficiency of the prism.

[0041] like Figure 3 As shown, the lifting mechanism 2 includes a second electric push rod 21 and a support block 22 installed at the piston rod end of the second electric push rod 21. A third electric push rod 23 is installed on one side of the support block 22. The clamping block 51 is installed at the piston rod end of the third electric push rod 23. The support block 22 and the clamping block 51 are connected by two telescopic rods 24. The two telescopic rods 24 increase the connection force between the support block 22 and the clamping block 51, so that the clamping block 51 can maintain stable movement. The second electric push rod 21 drives the support block 22 and the clamping block 51 to move up or down, so as to bring the clamped material 6 held by the clamping block 51 into contact with or away from the lower grinding disc 4. The third electric push rod 23 can adjust the distance between the two clamping blocks 51, so that clamped materials 6 of different lengths can be clamped and fixed.

[0042] like Figure 9 As shown, the upper surface of the base 1 is provided with an mounting groove 16 for mounting two second electric push rods 21, which helps to reduce the space occupied by the second electric push rods 21 on the base 1.

[0043] like Figure 4 As shown, each clamping block 51 has multiple feeding slots 53 equidistantly arranged. The upper end of the clamping block 51 is movably connected to a limiting rod 52. The upper end of the clamping block 51 is provided with a limiting hole 54 for the limiting rod 52 to be inserted. When the clamping material 6 is placed in the feeding slot 53, after the limiting rod 52 is inserted, the lower surface of the limiting rod 52 abuts against the upper surface of the clamping material 6. The limiting rod 52 limits the clamping material 6 in the feeding slot 53, preventing the clamping material 6 from shifting during double-sided polishing.

[0044] like Figure 1 As shown, the diameter of the upper grinding disc 7 is the same as that of the lower grinding disc 4, and the upper grinding disc 7 and the lower grinding disc 4 are aligned. When the material clamp 6 is polished on both sides, the upper grinding disc 7 is located between the two clamping blocks 51 so that the lower grinding disc 4 and the material clamp 6 can better contact each other and perform double polishing.

[0045] like Figure 5-7 As shown, the limiting mechanism 15 includes a bidirectional screw 151 rotatably installed inside one of the clamping blocks 51. The two ends of the bidirectional screw 151 are threadedly connected to moving blocks 153. A limiting rod 154 is fixed to one side of the moving block 153. One end of the limiting rod 154 passes through one side of the clamping block 51 and extends to the outside. An elastic limiting member 155 is sleeved on the outside of the limiting rod 154 on the clamping block 51. One end of the elastic limiting member 155 is fixed to one side of the clamping block 51. The distance between the two limiting rods 154 is adjusted by the adjusting mechanism 152. By using the cooperation of the elastic limiting member 155 and the limiting rod 154, the polishing depth of the clamping material 6 can be effectively adjusted according to the polishing requirements of the clamping material 6, thereby reducing the phenomenon of over-polishing of the clamping material 6.

[0046] like Figure 6 As shown, the adjusting mechanism 152 includes a rotating shaft 1522 rotatably connected to one side of the chamber. A bevel gear 1521 is mounted on one end of the rotating shaft 1522 and in the middle of the bidirectional screw 151, and the two bevel gears 1521 mesh. An adjusting disk 1523 is mounted on the other end of the rotating shaft 1522. An adjusting rod 1525 is slidably connected to the adjusting disk 1523. The clamping block 51 has positioning holes 1524 arranged in a circular array on one side where the adjusting disk 1523 is mounted, allowing one end of the adjusting rod 1525 to be slidably inserted. During adjustment, pull the adjusting rod 1525 outward to move it away from the positioning hole 1524. Then, rotate the adjusting disc 1523 through the adjusting rod 1525. The two meshing bevel gears 1521 drive the bidirectional screw 151 to rotate, so that the bidirectional screw 151 drives the two moving blocks 153 to move in opposite directions through the threaded connection with the moving block 153. This adjusts the distance between the two moving blocks 153, thereby adjusting the length of the limit rod 154 extending out of the clamping block 51, and further limiting the polishing depth of the clamping material 6.

[0047] like Figure 7As shown, the elastic limiting member 155 includes a stop block 1551 and a spring 1552. One end of the spring 1552 is fixed to the upper surface of the clamping plate, and the other end of the spring 1552 is fixed to the stop block 1551. There is a gap between the stop block 1551 and the limiting rod 154. When the clamping material 6 contacts the upper grinding disc 7 and the lower grinding disc 4, the two stops 1551 are respectively embedded in one end of the abutment rod 11 and the upper surface of the base 1. When one end of the stop block 1551 contacts the end of the limiting rod 154, it indicates that the polishing depth of the clamping material 6 is completed, effectively preventing the clamping material 6 from being over-polished.

[0048] The abutment rod 11 is L-shaped. One end of the abutment rod 11 is fixed to the outer wall of one side of the fixed base 8. The other end of the abutment rod 11 is provided with a clearance hole 17 for the stop block 1551 to enter, so as to make the polishing depth limit when polishing the clamping material 6 on both sides by using the elasticity of the spring 1552.

[0049] like Figure 1 As shown, the first driving mechanism includes a first motor 13 and a rotating shaft 131 rotatably connected to the center of the collection tank 3. The first motor 13 is installed at the lower end of the base 1. Support feet are provided at the four corners of the lower surface of the base 1. One end of the rotating shaft 131 is connected to the output shaft of the first motor 13, and the other end of the rotating shaft 131 is fixed to the lower surface of the lower grinding disc 4. The rotating shaft 131 is driven to rotate by the first motor 13, so that the rotating shaft 131 drives the lower grinding disc 4 to rotate, so as to polish the lower surface of the clamping material 6 by the lower grinding disc 4.

[0050] The second drive mechanism includes a second motor (not shown in the figure) installed inside the fixed base 8. The output shaft of the second motor passes through one side of the fixed base 8 and is fixed to the upper grinding disc 7. The output shaft of the second motor is rotatably connected to the fixed base 8 through a coupling, so as to drive the upper grinding disc 7 to rotate through the second motor to polish the upper surface of the clamping material 6.

[0051] like Figure 9 As shown, the bottom of the collection tank 3 is provided with a drain hole 18 for communicating with the drain pipe 12. One end of the nozzle 14 is connected to the polishing liquid source through a diaphragm pump so as to spray polishing liquid onto the surface of the clamping material 6 when polishing the clamping material 6 on both sides, thereby improving the polishing quality of the clamping material 6.

[0052] Based on the above description of a double-sided polishing apparatus for bonding a glass substrate 61 with a long strip prism, the present invention also provides a double-sided polishing process for bonding a glass substrate 61 with a long strip prism, comprising the following steps:

[0053] S1. Multiple prism strips are bonded to a 4-5mm thick glass substrate 61 to obtain the product to be processed, such as... Figure 10 As shown;

[0054] S2. Using laser cutting, the glass substrate 61 and the prism strip are cut together to obtain a strip-shaped product, such as... Figure 11 As shown;

[0055] S3. Install multiple strip-shaped products on the clamping mechanism 5 in pairs back to back, and then use the lifting mechanism 2 to drive the strip-shaped products to contact the lower grinding disc 4. Then move the upper grinding disc 7 to contact the strip-shaped products for double-sided polishing.

[0056] S4. Adjust the limiting distance of the limiting mechanism 15 to limit the polishing depth of the strip product until the prism polishing is completed before performing the degumming operation.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
