[0022] Specific implementation examples are given below.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, a membrane switch feeding device includes a frame 11, on which multiple rotating shafts 13 are rotatably connected. A sprocket is fixedly connected to each rotating shaft 13, and a chain 14 is mounted on each sprocket. A motor 12 is fixedly connected to the side of the frame 11, and the output end of the motor 12 is fixedly connected to the rotating shafts 13. Multiple chain plates 15 are mounted on the chain 14, and supports 16 are fixedly connected to each chain plate 15. Sliding grooves are formed at both ends of each support 16. Each of the two sliders 17 is slidably connected. The top of each slider 17 is provided with a clamping seat 18. The bottom of each slider 17 is hinged to a connecting rod 19. The bottom end of the connecting rod 19 is hinged to a base 23. The bottom of the chain plate 15 is provided with a lifting assembly. The lifting assembly includes a vertical rod 22 and a circular roller 21. The vertical rod 22 is fixed to the side of the base 23 away from the chain plate 15. The circular roller 21 is fixed to the frame 11. The ends of the circular roller 21 and the vertical rod 22 are corresponding to each other.

[0025] In use, a rotating shaft 13, sprocket, chain 14, motor 12 and chain plate 15 are installed on the frame 11 to form a plate chain conveyor. The chain plate 15 is driven by the motor 12 to move. A support 16 is installed on the top of the chain plate 15. Clamps 18 are installed on both sides of the support 16. The two clamps 18 are used to clamp the edges of the membrane switch circuit board from both sides to fix the membrane switch circuit board, improve the stability of transportation, and facilitate conveying assembly and gripping by other equipment.

[0026] In use, the clamp 18 slides in the groove via the slider 17, thereby opening and closing the clamp 18. The bottom of the slider 17 is connected to the base 23 via the connecting rod 19. The opening and closing of the clamp 18 is controlled by controlling the up and down movement of the base 23. Multiple rollers 21 are provided, and the rollers 21 are located in the feeding area and the unloading area. When the vertical rod 22 and the roller 21 are aligned, the roller 21 will lift the vertical rod 22 and move it upward. Then, the clamp 18 will open via the connecting rod 19. After separating from the roller 21, the base 23 will close the clamp 18 under the action of gravity for fixation.

[0027] Furthermore, such as Figure 1-5 As shown, a slide rail 3 is fixedly connected inside the slide groove. The side of the slider 17 has a groove at the position corresponding to the slide rail 3. The slide rail 3 is inserted into the groove and slidably connected to it. A rod 42 is fixedly connected to the chain plate 15. A sliding sleeve 41 is fixedly connected to the base 23 at the position corresponding to the rod 42. The rod 42 passes through the sliding sleeve 41 and slidably connects to it. A spring 5 is sleeved on the rod 42. The spring 5 is located between the base 23 and the sliding sleeve 41.

[0028] In use, the slide rail 3 is inserted into the groove, and the slide rail 3 and the groove are slidably connected, which can guide the slider 17, improve the stability of the clamp 18 and the slider 17, and reduce the wobbling of the clamp 18. The rod 42 and the sliding sleeve 41 are set up, and the sliding sleeve 41 slides on the rod 42 to guide and improve stability. The spring 5 is used to support the base 23, so as to facilitate the fixing effect of the clamp 18 on the circuit board.

[0029] Furthermore, such as Figure 1-5 As shown, the side of the clamp 18 is provided with a protrusion, the shape of which is adapted to the edge of the circuit board of the membrane switch.

[0030] Example 2

[0031] Furthermore, such as Figure 1-5 As shown, the lifting assembly includes a magnetic block 61 and an electromagnet 62. The magnetic block 61 is fixedly connected to the side of the base 23 away from the chain plate 15. A bracket is fixedly connected to the frame 11. The electromagnet 62 is fixedly connected to the bracket. The positions of the electromagnet 62 and the magnetic block 61 are corresponding.

[0032] In this embodiment, a magnetic block 61 is installed on the base 23, and an electromagnet 62 is installed in the feeding and unloading areas of the membrane switch. When the electromagnet 62 is energized, its magnetic block 61 and the base 23 move upward under the action of magnetic force, thereby causing the two clamps 18 to open.

[0033] Working principle: In use, a rotating shaft 13, sprocket, chain 14, motor 12 and chain plate 15 are installed on the frame 11 to form a plate chain conveyor. The chain plate 15 is driven by the motor 12 to move. A support 16 is installed on the top of the chain plate 15. Clamps 18 are installed on both sides of the support 16. The two clamps 18 are used to clamp the edges of the membrane switch circuit board from both sides to fix the membrane switch circuit board, improve the stability of transportation, and facilitate conveying assembly and gripping by other equipment.

[0034] In use, the clamp 18 slides within the groove via the slider 17, thereby opening and closing the clamp 18. The bottom of the slider 17 is connected to the base 23 via the connecting rod 19. The opening and closing of the clamp 18 is controlled by controlling the up and down movement of the base 23. Multiple circular rollers 21 are provided, located in the loading and unloading areas. When the vertical rod 22 and the circular roller 21 are aligned, the circular roller 21 will lift the vertical rod 22 and move it upward. Then, the clamp 18 opens via the connecting rod 19 and separates from the circular roller 21. Under the action of gravity, the base 23 causes the clamp 18 to close and be fixed. In use, the slide rail 3 is inserted into the groove and slidably connected to the groove, which can guide the slider 17, improve the stability of the clamp 18 and the slider 17, and reduce the wobbling of the clamp 18. The rod 42 and the sliding sleeve 41 are set up, and the sliding sleeve 41 slides on the rod 42 to guide and improve stability. The spring 5 is used to support the base 23, so as to maintain the fixing effect of the clamp 18 on the circuit board.
