Description

Technical Field

[0001] This utility model relates to the field of LCD display manufacturing technology, specifically to a pin cutting device for LCD display manufacturing. Background Technology

[0002] A Chinese patent, CN220278601U, describes a device for cutting the pins of an LCD display screen. It includes a laser cutting table with a laser emitter fixed to one side surface. The laser emitter's laser end extends into the inner cavity of the laser cutting table. A tray is provided on the upper part of the laser cutting table, and a chip positioning groove is formed on the upper surface of the tray. A pin through-hole is formed on the inner bottom wall of the chip positioning groove. This invention uses a lifting mechanism, a lifting screw thread, and a lifting sleeve to drive a lifting slider to slide downwards along a lifting groove. This allows for flexible adjustment of the distance between the tray and the laser cutting table, thereby controlling the depth of the chip pins inserted into the pin positioning hole so that the laser emitter can laser-cut them according to the required length.

[0003] Through a search of the aforementioned patent technologies, we found that such solutions still have some drawbacks when cutting pins: During cutting, existing technologies such as those mentioned in the patents can usually only cut a small number of product pins at a time. When there are a large number of products whose pins need to be cut, it is necessary to repeat the operation of installing and removing individual products from the shelf more often. In addition, it is necessary to wait for all products on the shelf to be removed and installed before the next cutting operation can be carried out. This method is relatively troublesome for workers and makes it difficult to improve the cutting efficiency of product pins. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pin cutting device for LCD display production, comprising a worktable, a product limiting component and a support frame disposed on the top of the worktable; the product limiting component includes a limiting frame and a positioning block one, the limiting frame being disposed on the top of the worktable, the positioning block one being disposed inside the limiting frame, and a plurality of positioning holes being equidistantly opened on one side of the positioning block one, and a silicone sleeve being disposed in each positioning hole; a storage frame is fixed to the bottom of the back of the worktable, and a positioning block two is slidably connected inside the storage frame; a cylinder is installed on the top of the support frame, an upper cutting component driven by the cylinder is disposed at the bottom of the support frame, and a lower cutting component is disposed on the top of the worktable at a position corresponding to the upper cutting component.

[0006] As a further embodiment of this utility model: one side of the limiting frame is open and the other side is closed. The inner top wall and inner bottom wall of the limiting frame are provided with sliding grooves. The top and bottom of the positioning block one are fixed with sliders. The positioning block one is slidably connected to the inner wall of the limiting frame from the open side of the limiting frame, and the slider is slidably connected in the sliding groove. A pull handle is also fixed on one side of the positioning block one.

[0007] As a further embodiment of this utility model: the top of the workbench is provided with a movable groove, and the top of the workbench and the positions on both sides of the movable groove are provided with limit grooves. The bottom of the limit frame is fixed with a movable block, and the bottom of the limit frame and the positions on both sides of the movable block are fixed with limit blocks. The movable block is slidably connected in the movable groove, and the limit block is slidably connected in the limit groove.

[0008] As a further embodiment of this utility model: an adjusting rod is rotatably connected to the front of the workbench and placed inside the movable groove. The adjusting rod has a thread on a section of its body in the movable groove. The threaded part of the adjusting rod passes through the movable block. One end of the adjusting rod is fixed to a screw block, and the other end is rotatably connected to the inner wall of the movable groove.

[0009] As a further embodiment of this utility model: a cavity is provided inside the workbench at the position of the top of the adjusting rod, and a clamping screw is threadedly connected to the top of the workbench at the position corresponding to the cavity, which penetrates into the cavity. The bottom of the clamping screw is rotatably connected to a pressure plate that is slidably connected to the inner wall of the cavity, and a clamping rubber is fixed to the bottom of the pressure plate.

[0010] As a further embodiment of this utility model: the upper blade assembly includes a mounting plate and an upper blade. The top of the mounting plate is fixed to the power output shaft of the cylinder at the center position. The upper blade is detachably mounted on the bottom of the mounting plate by bolts. The upper blade is designed with a slanted cut. Limiting rods are fixed on both sides of the top of the mounting plate. The top of the limiting rods extends through to the top of the support frame.

[0011] As a further embodiment of this utility model: the lower blade assembly includes a second mounting plate and a lower blade. The second mounting plate is fixed on the workbench, and the lower blade is detachably mounted on the top of the second mounting plate by bolts. The lower blade is also designed with a beveled cut.

In addition, with the use of positioning block two, when the products in positioning block one are being cut pins, the next batch of products to be cut pins can be conveniently installed in positioning block two. After the pins of the products in positioning block one are cut, positioning block one can be pulled out and positioning block two carrying multiple products can be directly inserted into the limiting frame.

[0017] This solution, through the alternating use of positioning block one and positioning block two, can achieve the simultaneous cutting of multiple product pins, as well as the simultaneous displacement and installation of multiple products from the cutting position. This results in higher efficiency and significantly improves the cutting efficiency of product pins. Furthermore, it is simpler to operate for workers, allowing the installation of the next batch of products while the product cutting is in progress, facilitating direct use afterward.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 A pin cutting device for LCD display production includes a worktable 1. A product limiting component 2 and a support frame 3 are mounted on the top of the worktable 1. The product limiting component 2 includes a limiting frame 201 and a positioning block 202. The limiting frame 201 is located on the top of the worktable 1, and the positioning block 202 is located inside the limiting frame 201. Multiple positioning holes 203 are equidistantly arranged on one side of the positioning block 202, and a silicone sleeve 12 is provided in each positioning hole 203. The silicone sleeve 12 protects and dampens the inserted product body 19, ensuring the stability of the product body 19 in the positioning hole 203. Simultaneously, the silicone sleeve 12 can be removed from the positioning hole 203, allowing for easy insertion of silicone sleeves 12 of different sizes into the positioning hole 203, thereby enabling the cutting of product bodies 19 of different sizes. The installation allows the device to perform pin cutting on product bodies 19 of different sizes, improving its applicability. A storage frame 20 is fixed to the bottom of the back of the workbench 1. A positioning block 21 is slidably connected inside the storage frame 20. The shape, structure, and size of the positioning block 21 are the same as those of the positioning block 202. A cylinder 5 is installed on the top of the support frame 3. An upper cutting assembly 6 driven by the cylinder 5 is set at the bottom of the support frame 3. A lower cutting assembly 7 is set on the top of the workbench 1 at a position corresponding to the upper cutting assembly 6. A waste collection frame 4 is also slidably connected on the top of the workbench 1 at a position on one side of the lower cutting assembly 7. The waste collection frame 4 can slide out from the side of the workbench 1. When a certain amount of waste is collected in the waste collection frame 4, the operator can pull out the waste collection frame 4 and process the waste in the waste collection frame 4 uniformly.

[0027] Please see Figure 1 and Figure 2 In this embodiment, one side of the limiting frame 201 is open and the other side is closed. The inner top wall and inner bottom wall of the limiting frame 201 are provided with sliding grooves. The top and bottom of the positioning block 202 are fixed with sliders. The positioning block 202 is slidably connected to the inner wall of the limiting frame 201 from the open side, and the slider is slidably connected in the sliding groove. A pull handle 13 is also fixed on one side of the positioning block 202.

[0028] Specifically, pulling handle 13 can cause positioning block 202 to enter or slide out of the limiting frame 201. Since one side of the limiting frame 201 is closed, when one side of positioning block 202 slides into the closed side of the limiting frame 201, the other side of positioning block 202 is flush with the open side of the limiting frame 201, which can quickly achieve the positioning of positioning block 202 and facilitate the rapid progress of cutting operations.

[0029] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the top of the workbench 1 is provided with a movable groove 8, and the top of the workbench 1 and the positions on both sides of the movable groove 8 are provided with limiting grooves 9. The bottom of the limiting frame 201 is fixed with a movable block 15, and the bottom of the limiting frame 201 and the positions on both sides of the movable block 15 are fixed with limiting blocks 14. The movable block 15 is slidably connected in the movable groove 8, and the limiting block 14 is slidably connected in the limiting groove 9. An adjusting rod 10 placed inside the movable groove 8 is rotatably connected to the front of the workbench 1. The adjusting rod 10 has a thread on a section of its body in the movable groove 8. The threaded part of the adjusting rod 10 passes through the movable block 15. One end of the adjusting rod 10 is fixed with a screw block, and the other end is rotatably connected to the inner wall of the movable groove 8.

[0030] Specifically, after loosening the clamping screw 11, the adjusting rod 10 can be rotated by turning the screw block on the adjusting rod 10. When the adjusting rod 10 rotates, the threaded part of the adjusting rod 10 can push the movable block 15 to slide in the movable groove 8, and drive the limiting frame 201 to move on the top of the worktable 1, so as to adjust the distance between the limiting frame 201 and the upper blade 602 and the lower blade 702, thereby adjusting the PIN cutting length requirements of different product bodies 19. When the limiting frame 201 moves on the top of the worktable 1, the limiting block 14 at the bottom of the limiting frame 201 can slide in the limiting groove 9, thereby ensuring the stability and straightness of the limiting frame 201 during movement.

[0031] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, a cavity 16 is provided inside the workbench 1 at the position of the top of the adjusting rod 10. A clamping screw 11 is threadedly connected to the top of the workbench 1 at the position corresponding to the cavity 16 and passes through the cavity 16. A pressure plate 17 is rotatably connected to the bottom of the clamping screw 11 and is slidably connected to the inner wall of the cavity 16. A clamping rubber 18 is fixed to the bottom of the pressure plate 17.

[0032] Specifically, after the adjusting rod 10 has finished rotating, in order to prevent the limiting frame 201 from becoming unstable due to the rotation of the adjusting rod 10, the clamping screw 11 is turned to drive the pressure plate 17 to move down in the cavity 16, thereby causing the clamping rubber 18 to press against the adjusting rod 10. Thus, the damping of the clamping rubber 18 and the pressure applied by the clamping screw 11 are used to stabilize the adjusting rod 10 and prevent it from rotating and affecting the stability of the limiting frame 201.

[0033] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the upper blade assembly 6 includes a mounting plate 601 and an upper blade 602. The top of the mounting plate 601 is fixed to the power output shaft of the cylinder 5 at the center position. The upper blade 602 is detachably mounted on the bottom of the mounting plate 601 by bolts. The upper blade 602 is designed with a beveled cut. Limiting rods 6011 are fixed on both sides of the top of the mounting plate 601. The top of the limiting rods 6011 extends through to the top of the support frame 3. The lower blade assembly 7 includes a mounting plate 701 and a lower blade 702. The mounting plate 701 is fixed on the worktable 1. The lower blade 702 is detachably mounted on the top of the mounting plate 701 by bolts. The lower blade 702 is also designed with a beveled cut. It also includes a product body 19, which is placed in a silicone sleeve 12. The pin of the product body 19 is located between the upper blade 602 and the lower blade 702.

[0034] Specifically, after cylinder 5 is started, its power output shaft can be used to push the upper blade assembly 6 downward, thereby pushing the upper blade 602 closer to the lower blade 702, which can cut the pin of the product body 19 placed between the two. Since the upper blade 602 and the lower blade 702 are designed with oblique cuts, the waste generated after cutting can fall directly into the waste collection box 4. When the upper blade assembly 6 is moving, the limit rod 6011 can be used to improve the stability of the mounting plate 601, ensuring that the mounting plate 601 moves stably and vertically. When the upper blade 602 and the lower blade 702 need maintenance or replacement after long-term use, the bolts on the mounting plate 601 and the mounting plate 701 can be loosened respectively, and the upper blade 602 and the lower blade 702 can be removed from the mounting plate 601 and the mounting plate 701 respectively for maintenance or replacement, thereby ensuring the normal operation of the cutting operation.

[0035] In use, the operator first inserts the product body 19 into the multiple positioning holes 203 of positioning block 1 202, respectively. The damping effect of the silicone sleeve 12 is used to limit and stabilize the product body 19, ensuring the pins of the product body 19 face outwards. Then, positioning block 1 202 is inserted into the limiting frame 201, and cylinder 5 is activated. The power output shaft of cylinder 5 pushes the upper blade 602 downwards to cut the pins of multiple product bodies 19. The waste generated during cutting falls into the waste collection box 4. While the product bodies 19 in positioning block 1 202 are being cut, there is a waiting period before the cutting is completed. During this time, the operator can insert the next batch of product bodies 19 requiring pin cutting into the multiple positioning holes 203 of positioning block 2 21. In the positioning hole 203, after the pins of the product body 19 in the positioning block 1 202 are cut, the operator can directly pull out the positioning block 1 202 from the limiting frame 201, and then insert the positioning block 21 into the limiting frame 201. This allows for direct cutting of the pins of the product body 19 in the positioning block 21. Similarly, when the pins of the product body 19 in the positioning block 21 are being cut, the product body 19 that has been cut in the positioning block 1 202 can be taken out, and a new product body 19 that needs to have its pins cut can be installed. By alternating the use of the positioning block 1 202 and the positioning block 21, the waiting time can be fully utilized, thereby effectively improving the cutting efficiency when there are a large number of product bodies 19.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
