Description

Technical Field

[0001] This invention relates to the field of LED modules, and more particularly to a film cutting and trimming system for the fabrication of Micro LED modules. Background Technology

[0002] With the development of LED technology, Micro LED (micro light-emitting diode) display technology has emerged, offering higher brightness, better luminous efficiency, and lower power consumption than OLED (organic light-emitting diode), showing great application potential. However, existing Micro LED modules require cutting during use, necessitating fixation to ensure cutting stability. Current Micro LED module cutting and fixing structures generally only achieve a single form of fixation, applicable only to modules of a single shape and size, such as rectangular or circular modules. They cannot accommodate irregularly shaped or small modules, and are prone to damage during clamping. Summary of the Invention

[0003] To address the technical problem that existing Micro LED module cutting and fixing structures can only achieve a single form of fixing and can only be applied to clamping modules of a single shape and size, such as rectangular or circular, and cannot adapt to the clamping and fixing of irregularly shaped modules and small modules, this invention provides a film material cutting and trimming system for Micro LED module fabrication.

[0004] The present invention is achieved by the following technical solution: a film material cutting and trimming system for Micro LED module preparation.

[0005] As a further improvement to the above solution, a film cutting and trimming system for Micro LED module fabrication includes a main body, which comprises:

[0006] The multi-functional clamping mechanism for film materials can achieve the purpose of multi-functional clamping of LED modules;

[0007] The membrane material cutting mechanism performs laser cutting on the LED module held by the multi-functional membrane material clamping mechanism;

[0008] The main body of the LED module is placed above the multi-functional clamping mechanism for the film material.

[0009] The multi-functional clamping mechanism for membrane materials includes:

[0010] The support base supports the main body of the multi-functional clamping mechanism for the membrane material; the lifting rod is connected to the support base; the sliding rod is installed above the support base; the slider is sleeved on the outer surface of the sliding rod and moves on the sliding rod; the return spring is connected above the slider, with its bottom end connected to the slider and its top end connected to the mounting platform; the mounting platforms form a circumferential shape.

[0011] Lifting platform;

[0012] A connecting shaft is movably connected to the lifting platform; a support shaft is connected at one end to the connecting shaft; a movable shaft is connected at the other end of the support shaft, and a mounting platform is connected to the outside of the movable shaft, with a clamping block connected to the outer surface of the mounting platform. A hydraulic column is connected above the lifting platform; a loading platform is connected to the hydraulic column, and the LED module body is placed above the loading platform.

[0013] The LED module body is placed on the platform. When it needs to be fixed, the lifting rod descends, causing the lifting platform connected above it to descend as well. The outer edge of the lifting platform drives the connecting shaft to rotate synchronously, which in turn drives the support shaft to move. The movable shaft connected to the top of the support shaft moves synchronously, which in turn drives the mounting platform connected to it to move synchronously. The mounting platform drives the return spring and the slider to move synchronously, and the slider drives the sliding rod to move synchronously. At this time, the mounting platform drives the clamping block to clamp laterally. When the LED module body is large, during the inward clamping process, the clamping block abuts against the side of the LED module body (e.g., ...). Figure 4 (As shown in the diagram), the clamping block clamps the LED module body, ensuring the stability of the LED module body;

[0014] While the aforementioned movable shaft drives the connected mounting platform to move synchronously, when the LED module body is small in size, the mounting platform, during its movement, maintains a compressed return spring state as the support shaft continues to pull. The mounting platform gradually and slowly compresses the return spring, causing the slider to move on the slide rail. The mounting platform thus gradually closes, compresses, and presses downwards, thereby clamping the LED module body from above (e.g., ...). Figure 5 As shown in the figure, the LED module body is clamped and fixed, thereby achieving the clamping and fixing of the small-volume LED module body.

[0015] As a further improvement to the above solution, the connecting shaft is inserted into the lifting platform through a set of shafts, and the connecting shaft deflects on the lifting platform through the shafts; the movable shaft is inserted into the mounting platform through a set of shafts, and the movable shaft deflects on the mounting platform through the shafts.

[0016] As a further improvement to the above solution, the circumferential diameter of the mounting platform is larger than that of the platform; the clamping block clamps the LED module body from the side and from the top and bottom; the clamping block is made of flexible material.

[0017] As a further improvement to the above solution, the membrane cutting mechanism includes:

[0018] Move the lever;

[0019] The system comprises the following components: a movable block, which fits onto the outer surface of the movable rod; a support column, which is fixedly connected above the movable block; a support slide rod, which is connected above the support column; a locking block, which fits onto the outer surface of the support slide rod and moves along it; a movable base, which is mounted above the locking block; a receiving column, which is connected to the outside of the movable base; a laser cutting table, which is connected to the bottom end of the receiving column; and a laser cutting head, which is connected to the laser cutting table. The laser cutting head is located above the stage and cuts the LED module body.

[0020] In summary, after fixing the LED module body, by controlling the movement of the moving block on the moving rod, the moving block drives the support column to move synchronously, adjusting the lateral position of the laser cutting head. At the same time, by controlling the movement of the locking block on the support slide rod, the locking block drives the moving seat to adjust synchronously, and the moving seat drives the receiving column and the laser cutting table to adjust synchronously, controlling the laser cutting head to cut the clamped LED module body better.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In this invention, the mounting platform drives the reset spring and the slider to move synchronously. The slider drives the sliding rod to move synchronously. At this time, the mounting platform drives the clamping block to clamp laterally. When the LED module body is large, during the inward clamping process, the clamping block abuts against the side of the LED module body. The clamping block clamps the LED module body, ensuring the stability of the LED module body. At the same time, the clamping block is made of flexible material to avoid damage to the LED module body.

[0023] 2. In this invention, the mounting platform moves while maintaining the state of compressing the return spring by continuously pulling the support shaft. The mounting platform gradually and slowly compresses the return spring and drives the slider to move on the slide bar. The mounting platform thus gradually moves closer and compresses and presses down, thereby clamping the LED module body from above, thus clamping and fixing the LED module body, thereby achieving the clamping and fixing of small-volume LED module bodies.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1:

[0035] Please combine Figures 1-5 This embodiment proposes a film material cutting and trimming system for Micro LED module fabrication, including a device body 1, which includes:

[0036] The multi-functional clamping mechanism 2 for membrane materials can achieve the purpose of multi-functional clamping of LED modules;

[0037] The membrane material cutting mechanism 3 performs laser cutting on the LED module held by the membrane material multi-functional clamping mechanism 2;

[0038] LED module body 4, which is placed above the multi-functional clamping mechanism 2 for film material;

[0039] The multi-functional clamping mechanism 2 for membrane materials includes:

[0040] Support base 21 supports the main body of the multi-functional clamping mechanism 2 for membrane material; lifting rod 22 is connected to the support base 21; sliding rod 23 is installed above the support base 21; slider 24 is sleeved on the outer surface of the sliding rod 23 and moves on the sliding rod 23.

[0041] A reset spring 25 is connected above the slider 24, with its bottom end connected to the slider 24 and its top end connected to the mounting platform 26. The mounting platforms 26 form a circumferential shape, and the diameter of the circumferential shape formed by the mounting platforms 26 is larger than the diameter of the circumferential shape of the platform 213. A clamping block 27 clamps the LED module body 4 from the side and from the top and bottom. The clamping block 27 is made of flexible material.

[0042] Lifting platform 28;

[0043] A connecting shaft 29 is movably connected to a lifting platform 28; a support shaft 210 is connected at one end to the connecting shaft 29; a movable shaft 211 is connected at the other end of the support shaft 210, and a mounting platform 26 is connected to the outside of the movable shaft 211, with a clamping block 27 connected to the outer surface of the mounting platform 26.

[0044] The connecting shaft 29 is inserted into the lifting platform 28 through a set of shafts, and the connecting shaft 29 deflects on the lifting platform 28 through the shafts;

[0045] The movable shaft 211 is connected to the mounting platform 26 via a set of shafts, and the movable shaft 211 deflects on the mounting platform 26 via the shafts;

[0046] Hydraulic column 212 is connected above the lifting platform 28;

[0047] The platform 213 is connected to the hydraulic column 212, and the LED module body 4 is placed on top of the platform 213.

[0048] The implementation principle of the film cutting and trimming system for Micro LED module fabrication in this application embodiment is as follows:

[0049] The LED module body 4 is placed on the platform 213. When it is necessary to fix the LED module body 4, the lifting rod 22 is lowered by the operation of the lifting rod 22. The lifting rod 22 drives the lifting platform 28 connected above it to lower. The outer edge of the lifting platform 28 drives the connecting shaft 29 to deflect synchronously. The connecting shaft 29 drives the support shaft 210 to move synchronously. The movable shaft 211 connected to the top of the support shaft 210 moves synchronously. The movable shaft 211 drives the mounting platform 26 connected to it to move synchronously. The mounting platform 26 drives the return spring 25 and the slider 24 to move synchronously. The slider 24 drives the sliding groove rod 23 to move synchronously. At this time, the mounting platform 26 drives the clamping block 27 to clamp laterally. When the LED module body 4 is large, during the inward clamping process, the clamping block 27 abuts against the side of the LED module body 4 (e.g., Figure 4 (As shown in the figure), the clamping block 27 clamps the LED module body 4 to ensure the stability of the LED module body 4. At the same time, the clamping block 27 is made of flexible material to avoid damage to the LED module body 4.

[0050] While the aforementioned movable shaft 211 drives the connected mounting platform 26 to move synchronously, when the LED module body 4 is small in size, the mounting platform 26, during its movement, maintains a state of compressing the return spring 25 as the support shaft 210 continues to pull. The mounting platform 26 gradually and slowly compresses the return spring 25, causing the slider 24 to move on the slide rail 23. The mounting platform 26 thus gradually approaches and compresses, pressing down, thereby clamping the LED module body 4 from above (e.g., ...). Figure 5 As shown in the figure, the LED module body 4 is clamped and fixed, thereby achieving the clamping and fixing of the small-volume LED module body 4.

[0051] Example 2:

[0052] Please combine Figures 6-7 This embodiment proposes that the membrane material cutting mechanism 3 includes:

[0053] Moving lever 31;

[0054] A movable block 32 is fitted onto the outer surface of a movable rod 31; a support column 33 is fixedly connected above the movable block 32; a support slide rod 34 is connected above the support column 33; a locking block 35 is fitted onto the outer surface of the support slide rod 34 and moves on the support slide rod 34. A movable seat 36 is installed above the locking block 35; a receiving column 37 is connected to the outside of the movable seat 36; a laser cutting table 38 is connected to the bottom end of the receiving column 37; and a laser cutting head 39 is connected to the laser cutting table 38. The laser cutting head 39 is located above the stage 213 and cuts the LED module body 4.

[0055] In summary, after fixing the LED module body 4, by controlling the movement of the moving block 32 on the moving rod 31, the moving block 32 drives the support column 33 to move synchronously, adjusting the lateral position of the laser cutting head 39. At the same time, by controlling the movement of the locking block 35 on the support slide rod 34, the locking block 35 drives the moving seat 36 to adjust synchronously, and the moving seat 36 drives the receiving column 37 and the laser cutting table 38 to adjust synchronously, controlling the laser cutting head 39 to cut the clamped LED module body 4 better.

[0056] Specific implementation steps of this invention:

[0057] In use, the LED module body 4 is placed on the platform 213. When it is necessary to fix the LED module body 4, the lifting rod 22 is lowered by the operation of the lifting rod 22. The lifting rod 22 drives the lifting platform 28 connected above it to lower. The outer edge of the lifting platform 28 drives the connecting shaft 29 to deflect synchronously. The connecting shaft 29 drives the support shaft 210 to move synchronously. The movable shaft 211 connected to the top of the support shaft 210 moves synchronously. The movable shaft 211 drives the mounting platform 26 connected to it to move synchronously. The mounting platform 26 drives the return spring 25 and the slider 24 to move synchronously. The slider 24 drives the sliding groove rod 23 to move synchronously. At this time, the mounting platform 26 drives the clamping block 27 to clamp laterally. When the LED module body 4 is large, during the inward clamping process, the clamping block 27 abuts against the side of the LED module body 4 (e.g., Figure 4 (As shown in the figure), the clamping block 27 clamps the LED module body 4 to ensure the stability of the LED module body 4. At the same time, the clamping block 27 is made of flexible material to avoid damage to the LED module body 4.

[0058] While the aforementioned movable shaft 211 drives the connected mounting platform 26 to move synchronously, when the LED module body 4 is small in size, the mounting platform 26, during its movement, maintains a state of compressing the return spring 25 as the support shaft 210 continues to pull. The mounting platform 26 gradually and slowly compresses the return spring 25, causing the slider 24 to move on the slide rail 23. The mounting platform 26 thus gradually approaches and compresses, pressing down, thereby clamping the LED module body 4 from above (e.g., ...). Figure 5 As shown), the LED module body 4 is clamped and fixed, thereby achieving the clamping and fixing of the small-volume LED module body 4;

[0059] In summary, after fixing the LED module body 4, by controlling the movement of the moving block 32 on the moving rod 31, the moving block 32 drives the support column 33 to move synchronously, adjusting the lateral position of the laser cutting head 39. At the same time, by controlling the movement of the locking block 35 on the support slide rod 34, the locking block 35 drives the moving seat 36 to adjust synchronously, and the moving seat 36 drives the receiving column 37 and the laser cutting table 38 to adjust synchronously, controlling the laser cutting head 39 to cut the clamped LED module body 4 better.
