Description

Technical Field

[0001] This application relates to the field of diode technology, and more specifically, to a device for stripping light-emitting diodes. Background Technology

[0002] In the LED manufacturing process, stripping is a crucial step, the core task of which is to separate the LED chip from the carrier film or other substrate. As LED technology rapidly develops towards higher precision, especially in the manufacturing of high-end products such as MicroLED, the stripping process faces almost stringent requirements, demanding both extremely high precision and proper protection of the chip.

[0003] Traditional stripping tools typically employ rigid blades. However, when dealing with the complex shapes of LED chip surfaces, rigid blades exhibit significant limitations. Their inability to flexibly adjust contact with the chip surface makes achieving uniform contact difficult, easily leading to stress concentration. This problem is serious, as stress concentration can damage critical structures such as the LED chip's electrodes and epitaxial layers, affecting its electrical and optical performance, and directly resulting in reduced production yield and significantly increased production costs.

[0004] Furthermore, due to the proliferation of LED chips of various sizes and shapes, it is necessary to frequently change the appropriate stripping tools in actual production. This process is extremely cumbersome, consuming a significant amount of time and manpower, and severely hindering the improvement of production efficiency.

[0005] Given the aforementioned problems, it is of great significance to develop a tool that can adapt to the surface shape of LEDs, reduce stress concentration, and be applicable to stripping LED chips of various sizes.

[0020] 3. Beneficial effects

[0021] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0022] 1. In the feeding mechanism of this application, after the feeding motor starts, the output end drives the feeding roller to rotate, thereby pulling the carrier with LEDs forward. During the conveying process, the tension roller is rotatably connected to the lifting bracket through a ball bearing structure, and the lifting bracket can slide at one end of the frame. When the carrier becomes slack, the operator rotates the adjusting bolt, which is rotatably connected to the frame, causing the lifting bracket to move up and down, thereby changing the pressure of the tension roller on the carrier and adjusting the tension of the carrier. This ensures the stability of the carrier during the conveying process and avoids inaccurate LED positioning or deviation in the peeling process due to carrier slack, providing a stable material input for the subsequent peeling process. In the positioning mechanism, the electric push rod pushes the positioning fixture to rotate around the hinge point of the mounting groove. The system moves to allow the stripped LEDs and carrier to be collected in the receiving mechanism. An industrial camera in the vision positioning system, aided by a light source lens, captures images of the LEDs on the carrier. Image processing algorithms analyze the captured images to accurately calculate the LEDs' position. Upon receiving the position signal from the vision positioning system, the U-shaped frame of the positioning fixture uses a pneumatic telescopic rod to push the rubber clamps to clamp and position the LEDs on the carrier. Simultaneously, an infrared heater embedded in the U-shaped frame can heat the LEDs when necessary, reducing the adhesion between the LEDs and the carrier, facilitating subsequent stripping operations. Through this series of precise positioning actions, the accuracy of the LEDs' position during stripping is ensured, improving the accuracy and success rate of the stripping process.

[0023] 2. The elastic blade of this application is made of bendable beryllium bronze alloy, giving it excellent flexibility and elasticity. During the stripping process, the elastic blade can adaptively deform according to the complex shape of the LED chip surface. The beveled edge of the blade reduces cutting resistance and improves stripping efficiency. The wavy blade structure increases the contact area with the LED chip, further improving the stripping effect, effectively reducing stress concentration, minimizing damage to key structures such as chip electrodes and epitaxial layers, and improving the production yield of LED chips. The elastic adjustment device allows the adjusting screw to slide within the frame slot by rotating the adjusting nut, thereby adjusting the position of the blade mounting seat and changing the working position of the elastic blade. The spring provides elastic support for the elastic blade, and the compression degree of the spring can be adjusted by the adjusting nut, changing the elasticity of the elastic blade. The limiting ring and pressure bearing ensure the stability and smoothness of the adjusting screw during adjustment. Operators can flexibly adjust the elasticity and position of the elastic blade according to different specifications and shapes of LED chips to adapt to diverse stripping needs, reduce stress concentration damage to the chip, and improve the equipment's versatility for different LED chips.

[0024] 3. After the drive motor of the stripping drive mechanism of this application starts, the output end drives the lead screw to rotate. Since the slide frame is threadedly connected to the lead screw and sleeved outside the frame, the rotation of the lead screw causes the slide frame to move linearly along the frame. The slide frame is slidably connected to the elastic blade assembly, thereby transmitting the linear motion of the slide frame to the elastic blade assembly, driving the elastic blade to perform the stripping action according to the set trajectory. By controlling the speed and direction of the drive motor, the speed and direction of stripping can be precisely controlled, achieving precise stripping of LED chips and ensuring the efficiency and accuracy of the stripping process; when the receiving mechanism finishes stripping, the stripped... The LEDs and carriers fall into the receiving mechanism separately. The carriers fall directly into the carrier receiving box for collection. During the fall, the LEDs pass through an inclined screening grid and slide down the grid into the LED receiving box, achieving separation and collection of the LEDs and carriers. The screening grid, LED receiving box, and carrier receiving box are all made of anti-static materials, which can effectively prevent static electricity from damaging the LED chips, ensuring that the performance of the collected LED chips is not affected, improving product quality. The entire receiving process is orderly and efficient, realizing the classification and recycling of materials and optimizing the overall operation of the stripping equipment.

Detailed Implementation

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] Reference Figure 1-4 The LED stripping device described in this application includes: a frame 1, a feeding mechanism 2 for conveying a carrier with LEDs at one end of the frame 1, a positioning mechanism 3 for accurately positioning the LEDs on the carrier at the discharge end of the feeding mechanism 2, an elastic blade assembly 4 and a receiving mechanism 6 for collecting the stripped LEDs and carriers outside the positioning mechanism 3, the elastic blade assembly 4 including an elastic blade 41, a blade mounting base 42 and an elastic adjustment device 43, the elastic blade 41 being installed at one end of the blade mounting base 42, the elastic adjustment device 43 being installed between the blade mounting base 42 and the frame 1, and a stripping drive mechanism 5 for driving the elastic blade assembly 4 to perform stripping action being provided on one side of the elastic blade assembly 4.

[0039] This LED stripping device continuously feeds the carrier containing the LEDs to the positioning mechanism 3 via the feeding mechanism 2. The positioning mechanism 3 precisely positions the LEDs on the carrier, ensuring accurate positioning during the subsequent stripping process. Driven by the stripping drive mechanism 5, the elastic blade 41 in the elastic blade assembly 4 contacts the positioned LEDs and performs the stripping operation. The elastic adjustment device 43 can adjust the elasticity and position of the elastic blade 41 according to actual needs to accommodate LED chips of different specifications and shapes, reducing stress concentration and damage to the chips. After stripping, the collecting mechanism 6 collects the stripped LEDs and carriers separately, achieving material classification and recycling.

[0040] Reference Figure 8 and Figure 2 The LED stripping device described in this application includes a feeding mechanism 2 fixed to one side of the frame 1. A feeding roller 22 is fixed to the output end of the feeding motor 21. The feeding roller 22 is rotatably connected to one end of the frame 1. A tensioning device 23 is provided on one side of the feeding roller 22. The tensioning device 23 includes a tensioning roller 24. A lifting bracket 25 is rotatably connected to the outside of the tensioning roller 24 through a ball bearing structure. The lifting bracket 25 is limited to one end of the frame 1 and is slidably fitted. An adjusting bolt 26 is rotatably connected to the middle of the lifting bracket 25. The other end of the adjusting bolt 26 is rotatably connected to the frame 1.

[0041] This LED stripping device is started by a feeding motor 21, which drives the feeding roller 22 to rotate, thereby pulling the carrier with LEDs forward. The tensioning device 23 plays a role in adjusting the tension of the carrier. When the carrier becomes loose during the conveying process, the adjusting bolt 26 can be rotated to make the lifting bracket 25 move the tensioning roller 24 up and down, changing the pressure of the tensioning roller 24 on the carrier, thereby adjusting the tension of the carrier and ensuring the stability of the carrier during the conveying process. This prevents inaccurate LED positioning or deviations in the stripping process due to carrier looseness.

[0042] Reference Figure 9 and Figure 2The positioning mechanism 3 of the LED stripping device described in this application includes a positioning platform 31. A mounting groove is provided on one side of the positioning platform 31, and a positioning clamp 32 is hingedly installed in the mounting groove. An electric push rod 33 is hingedly installed between one side of the positioning clamp 32 and the frame 1, and a visual positioning system 34 containing an image processing algorithm is provided on the other side. The visual positioning system 34 is located above the positioning platform 31 and includes an industrial camera 38 fixed to one side of the frame 1. A light source lens 39 is sleeved on the outside of the industrial camera 38. The positioning clamp 32 includes a U-shaped frame 35 hinged in the mounting groove on one side of the positioning platform 31. Two pneumatic telescopic rods 36 are fixedly connected to the outside of the U-shaped frame 35 in a symmetrical structure. One end of the pneumatic telescopic rod 36 passes through the U-shaped frame 35 and is fixedly connected to a rubber clamp 37. The rubber clamp 37 slides with the U-shaped frame 35, and an infrared heater is embedded in the U-shaped frame 35 and hinged to the electric push rod 33.

[0043] This LED stripping device uses an electric push rod 33 to drive a positioning clamp 32 to rotate around the hinge point of the mounting groove, tilting it to collect the stripped LEDs and carrier into a receiving mechanism 6. The industrial camera 38 in the vision positioning system 34, assisted by a light source lens 39, captures images of the LEDs on the carrier. The built-in image processing algorithm analyzes the captured images to accurately calculate the LEDs' position information. Upon receiving the position signal from the vision positioning system 34, the U-shaped frame 35 of the positioning clamp 32 uses a pneumatic telescopic rod 36 to push a rubber clamp 37 to clamp and position the LEDs on the carrier. Simultaneously, an infrared heater embedded in the U-shaped frame 35 can heat the LEDs when necessary, reducing the adhesion between the LEDs and the carrier, facilitating subsequent stripping operations, and further improving the accuracy and success rate of stripping.

[0044] Reference Figure 4 and Figure 3 In the LED stripping device described in this application embodiment, the elastic blade 41 is made of bendable beryllium bronze alloy metal material, and its blade part has an inclined surface and a wavy structure.

[0045] This LED stripping equipment utilizes a flexible blade 41 made of bendable beryllium bronze alloy, giving it excellent flexibility and elasticity. During the stripping process, the flexible blade 41 can adaptively deform according to the complex shape of the LED chip surface, ensuring uniform contact between the blade and the chip surface and effectively reducing stress concentration. The beveled edge of the blade reduces cutting resistance and improves stripping efficiency. The wavy blade structure increases the contact area with the LED chip, further improving the stripping effect while reducing damage to critical structures such as chip electrodes and epitaxial layers, thus improving the production yield of LED chips.

[0046] Reference Figure 5 and Figure 6 The elastic adjustment device 43 in the LED stripping equipment described in this application includes an adjustment screw 44 that passes through the blade mounting seat 42 and is inserted and limited thereto. A spring 45 and a limiting ring 46 are sleeved on the outside of the adjustment screw 44. The spring 45 is located between the blade mounting seat 42 and the frame 1. The limiting ring 46 is connected and fixed to the adjustment screw 44 through a set screw structure. The adjustment screw 44 is limited to sliding in the groove of the frame 1 and is threadedly connected to an adjustment nut 47. Two pressure bearings 48 are sleeved on the outside of the adjustment screw 44 relative to the side of the adjustment nut 47 and the limiting ring 46. The blade mounting seat 42 has a bent structure and is fixedly connected to a dust removal device 7. The dust removal device 7 includes a vacuum cleaner 71 fixedly connected to one side of the blade mounting seat 42. The suction end of the vacuum cleaner 71 is fixedly connected to a dust suction hood 72 through a hose. The dust suction hood 72 is located outside the elastic blade 41 and is hinged to the blade mounting seat 42. A nylon filter bag 73 is sleeved on the output end of the vacuum cleaner 71.

[0047] This LED stripping device allows the adjusting screw 44 to slide within the slot of the frame 1 by rotating the adjusting nut 47, thereby adjusting the position of the blade mounting seat 42 and thus changing the working position of the elastic blade 41. The spring 45 provides elastic support for the elastic blade 41, and its compression can be adjusted by adjusting the adjusting nut 47 according to actual stripping needs, thus changing the elasticity of the blade 41. The limiting ring 46 and pressure bearing 48 ensure the stability and smoothness of the adjusting screw 44 during adjustment. The dust removal device 7 operates synchronously during the stripping process. The vacuum cleaner 71 sucks in debris, dust, and other impurities generated during stripping through the suction hood 72, which are then filtered through the nylon filter bag 73 and collected. This prevents secondary contamination of the LED chips, affecting chip performance and the production environment. The vacuum cleaner also accelerates airflow during dust removal, providing heat dissipation for the elastic blade 41.

[0048] Reference Figure 10 and Figure 1 The stripping drive mechanism 5 of the LED stripping device described in this application embodiment includes a drive motor 51 fixed to one side of the frame 1. A lead screw 52 is fixed to the output end of the drive motor 51. The lead screw 52 is rotatably connected to one side of the frame 1, and a sliding frame 53 is threaded on the outside of the lead screw 52. The sliding frame 53 is sleeved on the outside of the frame 1 and is slidably connected to the elastic blade assembly 4.

[0049] This LED stripping device is started by a drive motor 51, which drives the lead screw 52 to rotate. Since the sliding frame 53 is threadedly connected to the lead screw 52 and sleeved outside the frame 1, the rotation of the lead screw 52 causes the sliding frame 53 to move linearly along the frame 1. The sliding frame 53 is slidably connected to the elastic blade assembly 4, thereby transmitting the linear motion of the sliding frame 53 to the elastic blade assembly 4, driving the elastic blade 41 to perform stripping action according to a set trajectory, achieving precise stripping of the LED chip. Furthermore, the speed and direction of stripping can be precisely controlled by adjusting the rotation speed and direction of the drive motor 51.

[0050] Reference Figure 11 and Figure 1 The LED stripping device described in this application includes a carrier receiving box 61 inserted into one side of the frame 1. An LED receiving box 62 is inserted inside the carrier receiving box 61. A screening grid 63 is provided on one side of the LED receiving box 62. The screening grid 63 is fixedly connected to the carrier receiving box 61 in an inclined state. The screening grid 63, the LED receiving box 62 and the carrier receiving box 61 are all made of antistatic material.

[0051] This LED stripping device, after stripping, separates the LEDs and carriers, which then fall into the collecting mechanism 6. The carrier falls directly into the carrier collecting box 61 for collection. During its descent, the LED passes through a screening grid 63, which is tilted, allowing the LED to slide along the grid into the LED collecting box 62, achieving separation and collection of the LED and carrier. The screening grid 63, LED collecting box 62, and carrier collecting box 61 are made of anti-static materials, effectively preventing static electricity from damaging the LED chips, ensuring that the performance of the collected LED chips is not affected, and improving product quality.

[0052] Reference Figure 7 and Figure 1 In the LED stripping device described in this application embodiment, the frame 1 is also provided with an integrated control panel 11 that integrates various control buttons and parameter setting interfaces of the device.

[0053] This LED stripping device features an integrated control panel 11, allowing operators to easily control and set various functions and parameters. For example, in the feeding mechanism 2, the speed of the feeding motor 21 can be adjusted via the control panel 11 to control the conveying speed of the carrier; in the positioning mechanism 3, the parameters of the vision positioning system 34 can be set to optimize positioning accuracy; for the elastic adjustment device 43, the elasticity and position parameters of the elastic blade 41 can be adjusted via the control panel 11; and in the stripping drive mechanism 5, the operating mode and speed parameters of the drive motor 51 can be set. The integrated control panel 11 makes the operation of the equipment more convenient and efficient, improving the overall operating performance and production efficiency of the equipment.

[0054] Working principle: First, the operator can adjust the operating parameters of each mechanism through the integrated control panel 11;

[0055] Next, the carrier containing LEDs is conveyed by the feeding mechanism 2. The feeding mechanism 2 first stably conveys the carrier with LEDs to the positioning mechanism 3. After the positioning mechanism 3 accurately positions the carrier containing LEDs, it clamps and fixes it to a limited position. Meanwhile, the infrared heater embedded in the U-shaped frame 35 heats the LEDs.

[0056] Then, the stripping drive mechanism 5 drives the elastic blade assembly 4 to strip the LEDs mounted on the carrier.

[0057] At the same time, when the flexible blade assembly 4 is peeling material, the dust removal device 7 installed on one side of it will absorb and clean the debris peeled off from the LED while the flexible blade assembly 4 is working.

[0058] Finally, after the stripping is completed, the electric push rod 33 pushes the positioning mechanism 3 to tilt, pouring the LEDs and carriers into the collecting mechanism 6, and classifying and collecting the stripped LEDs and carriers.
