Description

Technical Field

[0001] This invention relates to the field of LED lamp bead manufacturing technology, and specifically discloses an LED lamp bead stripping device. Background Technology

[0002] LEDs are semiconductor light-emitting diodes built on semiconductor transistors. Using LED technology, semiconductor light sources are small in size and can be packaged in a planar manner. Common LED tubes are mostly made of a large number of semiconductor chips. During the production of LED chips, the manufactured LED chips need to be peeled off from the lamp holder and then woven together.

[0003] For example, patent application number 2019105764090 discloses an LED stripping device, including a feeding device and a rotary stripping device. The stripping inlet of the rotary stripping device is connected to the feeding device. It also includes a vibration conveying device, which comprises a conveying surface for conveying LED supports and a vibration mechanism for causing the LED supports on the conveying surface to vibrate up and down. The inlet end of the conveying surface is connected to the LED support outlet of the rotary stripping device. Existing stripping devices require workers to place LED light frames sequentially on the stripping device before stripping, which wastes labor. Furthermore, given the high production efficiency of LED beads, relying entirely on manual placement of the LED light frames reduces stripping efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an LED chip stripping device to solve the technical problem that existing stripping devices require workers to manually place the LED chip holders one by one on the stripping device during the feeding process, resulting in low stripping efficiency.

[0006] Furthermore, the clamping mechanism includes a fixing frame, on which a first fixing groove is formed. Two sets of first mating frames are fixedly connected to both sides of the fixing frame, and a through groove is provided between the two sets of adjacent first mating frames. A second fixing groove is formed on the first mating frame, and several sets of fixing blocks are clamped in the second fixing groove. Two adjacent sets of fixing blocks are in contact with each other. Several sets of locking blocks are provided on each of the several sets of fixing blocks. One side of each locking block is inclined. The several sets of locking blocks are all inserted into the first mating frame. Several sets of LED bead plates are arranged between the four sets of first mating frames. The several sets of LED bead plates and the several sets of fixing blocks are staggered. The LED bead plates are in contact with the locking blocks located on the same horizontal plane, and the several sets of LED bead plates are not in contact with each other.

[0007] Furthermore, the installation mechanism includes a connecting column, which is rotatably connected to the first worktable. The connecting column is equipped with a rotating device and has several sets of first sliding grooves. The fixing frame is equipped with a connecting rod and a sliding block. The connecting rod and the sliding block are slidably locked in the several sets of connecting columns. A lifting assembly is provided below the clamping mechanism aligned with the conveying device.

[0008] Furthermore, the lifting assembly includes a first lifting device, which is fixedly connected to a first sliding groove. A movable first moving block is provided on the first lifting device, and a second mating frame is fixedly connected to the first moving block. The second mating frame has a U-shaped cross-section and is in contact with the corresponding fixed frame.

[0009] Furthermore, the feeding mechanism includes a second lifting device, which is fixedly connected to the first worktable. The second lifting device includes a movable second movable block, on which a first connecting frame and a second mating frame are fixedly connected. The connecting column passes through the first connecting frame, and the second mating frame contacts the corresponding fixed frame. A support frame is provided on the first worktable, and a cylinder is provided on the support frame. The telescopic end of the cylinder is fixedly connected to the first mating block, and both ends of the first mating block are inclined. The first mating block is aligned with the through groove. Two sets of limiting blocks are fixedly connected to the first worktable, and the clamping mechanism is located between the two sets of limiting blocks. Limiting grooves are provided on both sets of limiting blocks, and several sets of fixed blocks can be slidably locked in the limiting grooves. A fourth fixing groove is provided on the limiting block.

[0010] Furthermore, a sorting mechanism is provided on the first workbench, the sorting mechanism including a third lifting device, the third lifting device being fixedly connected to the first workbench, the third lifting device including a third movable block and a second connecting frame, the second connecting frame being provided with two sets of cooperating components; the two sets of limiting blocks are located between the two sets of cooperating components.

[0011] Furthermore, the mating assembly includes a second mating block, on which a rotatable connecting shaft and rollers are provided. Two sets of third connecting frames are fixedly connected to the first worktable. The rollers are located between the two sets of third connecting frames. The third connecting frames are provided with second sliding grooves. The two ends of the connecting shaft are respectively slidably engaged in the two sets of second sliding grooves.

[0013] The working principle and beneficial effects of this solution are as follows:

[0014] When it is necessary to peel the LED beads from the LED bead board, the installation mechanism first drives the corresponding clamping mechanism to rotate, aligning the clamping mechanism with the lifting component. Then, the lifting component is activated, driving the corresponding clamping mechanism to move downwards, thus lowering the clamping mechanism. As the clamping mechanism descends, it causes the connecting rod to slide on the connecting column, while the sliding block slides in the first sliding groove. As the clamping mechanism descends, it cooperates with the conveying device, which moves the LED bead board to the LED bead peeling device. The LED bead peeling device peels the LED beads from the LED bead board, and the peeled LED beads are removed from the discharge port. The staff only needs to place a collection box at the discharge port to collect the peeled LED beads.

[0015] After the LED beads on the clamping mechanism are peeled off, the first lifting device moves upward quickly until the clamping mechanism moves to its initial position. Then, the rotating device is activated, which moves the clamping mechanism located on the lifting assembly to the feeding mechanism. At the same time, another clamping mechanism with a full LED bead board moves above the lifting assembly to continue peeling off the LED beads on the LED bead board. Meanwhile, the operator can load the LED bead board into the clamping mechanism without an LED bead board. Attached Figure Description

[0035] In practice:

[0036] When it is necessary to peel the LED beads from the LED bead board 211, firstly, the conveying device 106 and the LED bead peeling device 103 are started, and then the rotating device is started. The output end of the rotating device drives the connecting column 201 to rotate. When the connecting column 201 rotates, it drives several sets of connecting rods 203 and corresponding clamping mechanisms to rotate, so that the fixing frame 205 moves on the first worktable 101 until the clamping mechanism with the LED bead board 211 is aligned with the lifting assembly. Then the lifting assembly is started, driving the corresponding clamping mechanism to move downward, thereby driving the clamping mechanism to move downward. As the clamping mechanism descends, it causes the connecting rod 203 to slide on the connecting column 201, while the sliding block 204 slides in the first sliding groove 202. As the clamping mechanism descends, it cooperates with the conveying device 106, which moves the LED bead plate 211 to the LED bead peeling device 103. The LED bead peeling device 103 peels the LED beads off the LED bead plate 211, and the peeled LED beads are removed from the discharge port 104. The staff only needs to place a collection box at the discharge port 104 to collect the peeled LED beads.

[0037] When the lifting assembly is running, the first lifting device 301 is activated, which drives the first movable block 302 to move downwards. The first movable block 302 drives the second mating frame 303 to move. As the second mating frame 303 moves downwards, the clamping mechanism moves downwards along with it due to gravity. When the lowest LED bead plate 211 on the clamping mechanism comes into contact with the conveying device 106, the conveying device 106 drives the corresponding LED bead plate 211 to move. The LED bead plate 211 moves on the locking block 213. At this time, the clamping mechanism continues to move downwards, and the LED bead plate 211 separates from the locking block 213. Located between two sets of clamping blocks 213, the LED bead board 211 is only in contact with the conveying device 106 at this time. The conveying device 106 moves the LED bead board 211 out of the clamping mechanism. The LED bead board 211 moves with the conveying device 106 and finally enters the LED bead stripping device 103. After one set of LED bead boards 211 moves out of the clamping mechanism, the clamping mechanism continues to move downward, so that another set of LED bead boards 211 comes into contact with the conveying device 106. This process is repeated so that several sets of LED bead boards 211 can be quickly moved through the conveying device 106 into the LED bead stripping device 103, thereby improving the efficiency of stripping LED beads.

[0038] After the LED beads on one of the clamping mechanisms are peeled off, the first lifting device 301 moves upward quickly until the clamping mechanism moves to the initial position. Then, the rotating device is activated, and the rotating device moves the clamping mechanism located on the lifting assembly to the feeding mechanism. At the same time, another clamping mechanism with the LED bead board 211 is moved above the lifting assembly to continue peeling off the LED beads on the LED bead board 211. Meanwhile, the operator can put the LED bead board 211 into the clamping mechanism without the LED bead board 211.

[0039] When installing the LED bead board 211, the operator first activates the cylinder 403. The telescopic end of the cylinder 403 drives the first mating block 404 to slide within the third fixed groove 402 until the first mating block 404 aligns with the through groove 207. Then, the operator activates the second lifting device 304, which drives the second movable block 305 downward. The second movable block 305 drives the first connecting frame 306 and the corresponding second mating frame 303 downward. When the second mating frame 303 moves downward, it drives the corresponding fixed frame 205 downward. When the fixed frame 205 moves downward, it drives the first mating frame 206 and several sets of fixed blocks 212 downward. At this time, the locking block 213 passes through the locking groove 210. The fixed block 212 moves downward and contacts the inclined surface of the first mating block 404. 04 The inclined surface will drive the fixed block 212 to move in the second fixed groove 209, and at the same time drive the locking block 213 to slide in the locking groove 210 until one end of the locking block 213 is completely moved into the locking groove 210. At this time, the locking block 213 has not passed through the locking groove 210. At the same time, the fixed block 212 moves into the limiting groove 406, and the fixing frame 205 continues to move downward. Several groups of fixed blocks 212 move into the limiting groove 406 in sequence. The fixed blocks 212 located in the limiting groove 406 slide in the limiting groove 406 until all the fixed blocks 212 have moved into the limiting groove 406. Then the cylinder 403 is activated. The telescopic end of the cylinder 403 retracts, driving the first mating block 404 to move until the first mating block 404 moves to the initial position. At this time, the first mating block 404 will not interfere with the vertical movement of the clamping mechanism.

[0040] Then, the staff stacked several sets of LED bead boards 211 and moved them onto the fixing frame 205. At this time, the several sets of LED bead boards 211 were located between several sets of first mating frames 206. Then, the third lifting device 501 was activated. The third lifting device 501 drove the third movable block 502 to move upward. When the third movable block 502 moved, it drove the second connecting frame 503 and two sets of second mating blocks 504 to move. When the second mating blocks 504 moved, they drove the connecting shaft 505 and rollers 506 to move upward. The rollers 506 moved in the fourth fixing groove 407 and the through groove 207. At the same time, the connecting shaft 505 moved in the second sliding groove 508. When the rollers 506 moved, they moved several sets of fixing blocks 212 toward the LED bead boards 211, and drove them sequentially from bottom to top. When the fixing blocks 212 moved, they drove the locking blocks 213 into the locking grooves 210. When the locking block 213 moves, the inclined surface drives the LED bead plate 211 located above the locking block 213 to move upward until both ends of the LED bead plate 211 are above the horizontal plane of the locking block 213, so that there is a gap between the locking block 213 and the locking block 213 located below, which facilitates the subsequent movement of the LED bead plate 211 above the conveying device 106, making it easier to peel off the LED beads on the LED bead plate 211, thereby improving the efficiency of peeling off the LED beads; several sets of fixing blocks 212 lift the corresponding LED bead plates 211 in sequence, so that the several sets of LED bead plates 211 do not contact each other, and then the second lifting device 304 is activated again. The second lifting device 304 drives the second movable block 305 and the corresponding clamping mechanism to move upward, moving to the first worktable 101. At the same time, the third lifting device 501 is activated, so that the roller 506 moves to the initial position.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or its practicality.
