Description

Technical Field

[0001] The utility model relates to the technical field of diode processing, and specifically relates to a diode welding device. Background Art

[0002] A diode is a two-terminal electronic component with asymmetric conductance. An ideal diode has zero resistance between the two electrodes when forward-conducting, and infinite resistance when reverse-biased, that is, current is only allowed to flow through the diode in a single direction. Therefore, a diode has the characteristic of unidirectional conductivity and can play a rectifying role;

[0003] During the production and processing of diodes, it is necessary to connect them to a circuit board. Usually, the pins of the diode are inserted into the reserved holes on the circuit board, and then the pins are bent on the back side of the circuit board and then welded. In this process, it is very easy to cause the diode to be unstable in placement, affecting the welding accuracy. At the same time, there are many steps that require workers to hold by hand, which will increase the labor intensity of the workers and affect the overall processing efficiency. Summary of the Utility Model

[0004] In order to solve the above problems; the purpose of the utility model is to provide a diode welding device.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A diode welding device includes a base. The base is integrally L-shaped. A vertical positioning plate is provided on the vertical side of the base. Baffles are fixedly provided on the upper and lower sides of the inner wall of the positioning plate. Activity slots are opened at both ends of the positioning plate far from the vertical side of the base. Vertically arranged iron blocks are fixedly provided inside the activity slots. A horizontally arranged support plate is provided on the side of the positioning plate close to the activity slots. Grooves are opened at both ends of the support plate close to the activity slots. Pull rods are movably inserted into the grooves. Both ends of the pull rods penetrate through the support plate and one end is inserted into the activity slots. A magnetic block that attracts the iron block is fixedly provided at one end of the pull rod located inside the support plate. A damping chute is opened on the upper surface of the support plate. A damping slider for cooperating use is provided in the damping chute. The top of the damping slider is fixedly provided with an arc-shaped limiting sleeve. Horizontally arranged long plates are fixedly provided at the upper and lower ends of the vertical side of the positioning plate. A rotating rod is rotatably provided on the upper surface of the positioning plate close to the long plate. The rotating rod is rotatably provided on the adjacent long plate.

[0006] Preferably, two symmetrically arranged positioning blocks are provided at the bottom of the inner wall of the positioning plate. The lower surface of the positioning block is connected to a lead screw through a bearing. The bottom of the lead screw threadedly penetrates through the positioning plate.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment: As Figures 1-4 shown, the present invention provides a diode welding device, including a base 1. The base 1 is integrally arranged in an L shape. A vertical positioning plate 11 is provided on the vertical side of the base 1. Baffles 5 are fixedly arranged on the upper and lower sides of the inner wall of the positioning plate 11. Activity slots 13 are opened at both ends of the positioning plate 11 away from the vertical side of the base 1. An iron block 14 arranged vertically is fixedly arranged inside the activity slots 13. A horizontally arranged support plate 12 is provided on the side of the positioning plate 11 close to the activity slots 13. Grooves 15 are opened at both ends of the support plate 12 close to the activity slots 13. A pull rod 16 is movably inserted into the grooves 15. Both ends of the pull rod 16 penetrate through the support plate 12 and one end is inserted into the activity slots 13. A magnetic block 17 that attracts the iron block 14 is fixedly arranged at one end of the pull rod 16 located inside the support plate 12. A damping chute 2 is opened on the upper surface of the support plate 12. A damping slider 21 that is used in cooperation is arranged in the damping chute 2. The top of the damping slider 21 is fixedly provided with a limit sleeve 22 arranged in an arc shape. Horizontally arranged long plates 4 are fixedly arranged at the upper and lower ends of the vertical side of the positioning plate 11. A rotating rod 41 is rotatably arranged on the upper surface of the positioning plate 11 close to the long plate 4. The rotating rod 41 is rotatably arranged on the adjacent long plate 4.

[0018] A push block 18 is fixedly arranged at one end of the pull rod 16 located in the groove 15. A spring 19 is fixedly arranged between the push block 18 and the groove 15. The arranged spring 19 can enable the pull rod 16 to pull the magnetic block 17 away from the iron block 14. After adjusting the position of the support plate 12 and releasing the pull rod 16, the spring 19 can directly push the push block 18 to make the magnetic block 17 at the top of the pull rod 16 attract the iron block 14, so as to fix the position of the support plate 12, which is convenient for use.

[0019] Support blocks 24 are fixedly arranged at both ends of the support plate 12. A vertically arranged support rod 23 is fixedly arranged on the side wall of the positioning plate 11. The support blocks 24 can movably penetrate through the support rod 23. The arranged support rod 23 and support blocks 24 can ensure that when the cross plate moves up and down, the support plate 12 can always abut against the positioning plate 11 to prevent the pull rod 16 from disengaging from the activity slots 13.

[0020] A driving motor 42 is fixedly installed on the long board 4 at the top, and the output end of the driving motor 42 is coaxially fixed on the rotating rod 41. The set driving motor 42 can facilitate the staff to rotate the positioning plate 11, so that the circuit board and diode placed in the positioning plate 11 can be rotated to the back, so as to facilitate the welding of the pins of the diode that pass through the circuit board.

[0021] Two symmetrically arranged positioning blocks 31 are provided at the bottom of the inner wall of the positioning plate 11. A screw rod 3 is connected to the lower surface of the positioning block 31 through a bearing. The bottom thread of the screw rod 3 penetrates the positioning plate 11. The positioning block 31 can be pushed upward by rotating the screw rod 3, so that the positioning block 31 can position the circuit board placed in the positioning plate 11 to avoid shaking during subsequent welding with the pins of the diode that affects the welding effect; the top of the positioning block 31 is made of rubber material, and the provided rubber material can protect the circuit board when positioning to avoid excessive hard contact with the circuit board; vertically arranged upright poles 32 are fixed at both ends of the lower surface of the positioning block 31, and the bottom of the upright pole 32 movably penetrates the positioning plate 11, and the upright pole 32 is inserted into the positioning plate 11, so that when the screw rod 3 pushes the positioning block 31 to move up and down, the positioning block 31 can be ensured to move stably to avoid the positioning block 31 from being offset.

[0022] Working principle: When in use, the staff can put the circuit board welded with the diode into the positioning plate 11, so that its upper and lower ends are against the baffle 5, and then push the positioning block 31 upward by rotating the screw rod 3, so that the positioning block 31 is against the circuit board, so that the circuit board can be fully fixed on the positioning plate 11 to maintain stability;

[0023] Then the staff can pull the pull rod 16 to make the magnetic block 17 separate from the iron block 14, adjust the horizontal height of the entire support plate 12 downward, adjust it to the position where the diode is set on the circuit board, place the diode to be welded to the circuit board on the support plate 12, and then insert its pin into the hole reserved on the circuit board. At this time, the staff can directly pull the two damping sliders 21 downward so that the two symmetrically arranged limit sleeves 22 on the damping slider 21 directly limit the diode. Through the damping characteristics of the damping slider 21 and the damping chute 2, the position of the diode can be effectively limited. At this time, the driving motor 42 can drive the rotating rod 41 to rotate, thereby driving the entire positioning plate 11 to rotate one hundred and eighty degrees and directly rotate to the back of the circuit board. During the rotation process, it can be ensured that the diode is still in the set position. At this time, the staff can conveniently weld the pins of the diode and the circuit board on the back of the circuit board. Through the above operation, it is convenient to ensure that the set position between the two will not be affected when the diode is flipped to the back of the circuit board when welding the diode to the circuit board, thereby improving the subsequent overall welding work efficiency and accuracy.

[0024] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
