The number of the placement slots is eight;

[0008] A convenient mechanism is arranged in the box body for ejecting the finished products in the placement slots;

[0009] A moving mechanism is arranged in the chip mounting box for moving the chip mounting head.

[0010] In a possible design, the convenient mechanism includes eight top plates, eight inclined plates, eight moving plates, eight fixing frames, a first motor, and a first threaded rod. The outer sides of the eight top plates are respectively slidably connected to the inner wall of the placement groove. A moving hole is formed at the bottom of the placement groove, and a lifting plate is slidably connected to the inner wall of the moving hole. The top parts of the eight inclined plates are respectively fixedly connected to the bottom parts of the eight lifting plates. One side of each of the eight moving plates is slidably connected to the inner wall of one side of the box body. A first threaded hole is formed in the moving plate. The two ends of the first threaded rod are respectively rotatably connected to the inner walls of the two sides of the box body. One side of the first motor is fixedly connected to one side of the box body. The output end of the first motor penetrates through one side of the box body and is fixedly connected to one end of the first threaded rod. The first threaded rod is threadedly connected to the first threaded hole of the moving plate. The bottom parts of the eight fixing frames are respectively fixedly connected to the top parts of the eight moving plates. The same roller is rotatably connected to the inner walls of the two sides of the fixing frame, and the roller is in contact with the inclined plate.

[0011] In a possible design, the moving mechanism includes a cover body, a second motor, a second threaded rod, and a moving block. The top of the cover body is fixedly connected to the inner wall of the top of the patch box. One side of the second motor is fixedly connected to the inner wall of one side of the cover body. One end of the second threaded rod is fixedly connected to the output end of the second motor. The other end of the second threaded rod is rotatably connected to the inner wall of one side of the cover body. The top of the moving block is slidably connected to the inner wall of the top of the cover body. A second threaded hole is formed in the moving block. The second threaded rod is threadedly connected to the second threaded hole. The fixed part of the electric push rod is fixedly connected to the bottom of the moving block. The patch head is in the same horizontal direction as the placement groove.

[0012] In a possible design, a counterweight block for counterweighting the top plate is fixedly arranged at the bottom of the inclined plate.

[0013] In a possible design, a sliding groove for reducing the friction generated by the movement of the moving plate is formed in the inner wall of one side of the box body.

[0014] In a possible design, a magnet for magnetically fixing the opening and closing door is fixedly arranged on one side of the patch box, and an iron sheet is fixedly arranged on one side of the opening and closing door.

[0015] In a possible design, illuminating lamps for lighting are fixedly arranged on both sides of the inner wall of the top of the patch box.

[0016] In this application, the LED components to be pasted are placed on the top plate of the placement groove in the box body inside the pasting box. Each placement groove can hold one LED component, and there are a total of eight slots. When the light is poor, the lighting lamp on the top of the pasting box can be turned on to ensure sufficient light in the working area for easy operation. Then, close the opening and closing door, and magnetically fix the opening and closing door by the magnetic attraction of magnets. The material of the opening and closing door can be transparent glass. Start the second motor, and the second motor drives the second threaded rod to rotate. Since the second threaded rod is threadedly connected to the second threaded hole of the moving block, the moving block moves horizontally inside the cover body. The moving block drives the electric push rod and the connected pasting head to move directly above the LED component to be pasted, ensuring that the pasting head is in the same horizontal direction as the placement groove, and preparing for the pasting operation. The electric push rod is started, and the expansion and contraction of the expansion and contraction part of the electric push rod pushes the pasting head to descend, which can effectively paste the pasting head on the LED in the placement groove. After the pasting is completed, the electric push rod retracts, lifting the pasting head to the initial position, and then repeating the above work. Move the pasting head to the position of another placement groove for pasting. After all are pasted, the pasting head is lifted to the initial position by the electric push rod, and then start the first motor. The first motor drives the first threaded rod to rotate. Since the first threaded rod is threadedly connected to the first threaded hole of the moving plate, the moving plate will move horizontally along the inner wall of the box body. The fixed frame on the top of the moving plate moves accordingly, and the roller on it rolls along the inclined plate, pushing the inclined plate and the connected lifting plate to rise. The rise of the lifting plate drives the top plate to slide along the inner wall of the placement groove, ejecting the LED component in the placement groove, so that it is convenient to take out the finished products in multiple placement grooves. Through the set counterweight, when the second motor rotates in the reverse direction, the gravity of the top plate is increased by the counterweight, making it naturally descend and fall into the placement groove. Among them, the electric push rod, the first motor, the second motor, the lighting lamp and the pasting head need to be externally connected to a controller for control during use. The first motor and the second motor can be selected as stepping motors, and the stepping motors can rotate forward and backward. Secondly, when the counterweight drops to the lowest position, the counterweight will not contact the first threaded rod and will not affect the rotation of the first threaded rod.

[0017] The beneficial effects in the present utility model are as follows:

[0018] In the present utility model, for the described LED pasting device, through the convenient mechanism, the first motor drives the first threaded rod to rotate. Since the first threaded rod is threadedly connected to the first threaded hole of the moving plate, the moving plate will move horizontally along the inner wall of the box body. The fixed frame on the top of the moving plate moves accordingly, and the roller on it rolls along the inclined plate, pushing the inclined plate and the connected lifting plate to rise. The rise of the lifting plate drives the top plate to slide along the inner wall of the placement groove, ejecting the LED component in the placement groove, so that it is convenient to take out the finished products in multiple placement grooves;

[0019] In the present utility model, for the described LED chip mounting device, through the moving mechanism, the second motor drives the second threaded rod to rotate. Since the second threaded rod is threadedly connected to the second threaded hole of the moving block, the moving block moves horizontally within the cover body, and the moving block drives the electric push rod and the connected chip head to move to directly above the LED component to be chipped, thereby enabling the movement of the chip head and facilitating chip mounting.

[0020] In the present utility model, the convenient mechanism can facilitate the removal of the finished products in multiple placement slots, and the moving mechanism can move the chip head to facilitate chip mounting. BRIEF DESCRIPTION OF THE DRAWINGS
