[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: a pin welding device for circuit board processing, including a base 1, and a support plate 5 is rotatably arranged above the base 1.

[0031] Both ends of the top of the base 1 are fixedly connected to fixing plates 21, and rotating cylinders 10 are rotatably passed through both fixing plates 21. The rotating cylinders 10 are arranged horizontally and the two rotating cylinders 10 are arranged coaxially. The support plate 5 is fixedly connected between the two rotating cylinders 10.

[0032] One of the rotating drums 10 has a worm gear 4 fixedly fitted at the end away from the support plate 5, and a worm 3 is rotatably mounted on one side of a fixed plate 21 close to the worm gear 4. The worm 3 meshes with the worm gear 4, and one end of the worm 3 is fixedly connected to a turntable 2. By rotating the turntable 2, the worm 3 rotates, which drives the worm gear 4 to rotate, causing the rotating drum 10 and the support plate 5 to rotate.

[0033] The support plate 5 has several through slots 6 spaced apart, and each through slot 6 has a support seat 7 slidably mounted at both ends. The support plate 5 is equipped with a driving assembly, which drives the two support seats 7 in each through slot 6 to slide towards each other or away from each other.

[0034] The bottom surface of the support plate 5 is provided with a positioning groove 22, which communicates with several through grooves 6. Both ends of the positioning groove 22 are slidably connected to connecting plates 19. One connecting plate 19 is located at the bottom of the support base 7 at one end of the through groove 6, and the other connecting plate 19 is located at the bottom of the support base 7 at the other end of the through groove 6.

[0035] Several support seats 7 located at the same end of several through slots 6 are fixedly connected to the top of a corresponding connecting plate 19, and several support seats 7 located at the other end of several through slots 6 are fixedly connected to the top of another connecting plate 19. This causes the connecting plate 19 to move the support seats 7.

[0036] The drive component drives the two connecting plates 19 to slide towards each other or away from each other.

[0037] The drive assembly includes a motor 8, which is fixedly connected to one end of a rotating drum 10 without the worm gear 4. A lead screw 9 is fixedly connected to the output end of the motor 8, and the lead screw 9 rotates through the end faces of the corresponding rotating drum 10 and positioning groove 22. The other end of the lead screw 9 is rotatably connected to the inner wall of the positioning groove 22, and the lead screw 9 is parallel to the through groove 6. The motor 8 drives the lead screw 9 to rotate inside the positioning groove 22.

[0038] The lead screw 9 has two threaded sections with opposite directions of rotation, and two connecting plates 19 are threaded onto the two threaded sections respectively. When the lead screw 9 rotates, it drives the two connecting plates 19 to slide towards each other or away from each other.

[0039] Each support 7 has a groove 13, and a slide plate 11 is vertically slidably mounted on the top of each groove 13. One end of the slide plate 11 extends out of the groove 13.

[0040] Each end of the slide groove 13 is fixedly connected to a vertical rod 26, which is arranged vertically. The slide plate 11 is slidably fitted onto the corresponding two vertical rods 26. The vertical rods 26 position the slide plate 11 within the slide groove 13.

[0041] The end of the slide plate 11 is provided with a second slide bar 17 that slides vertically via a second spring 18.

[0042] The second slide rod 17 slides vertically through the end of the slide plate 11. A limiting plate 24 is fixedly connected to the top of the second slide rod 17, and a second clamping plate 25 is fixedly connected to the bottom of the second slide rod 17. The cooperation of the limiting plate 24 and the second clamping plate 25 ensures that the second slide rod 17 can only slide on the slide plate 11.

[0043] The second spring 18 is sleeved on the second slide bar 17 located at the bottom of the slide plate 11. The top end of the second spring 18 is fixedly connected to the bottom surface of the slide plate 11, and the bottom end of the second spring 18 is fixedly connected to the top surface of the second clamping plate 25. In the initial state, the second spring 18 pushes the second clamping plate 25 downward, causing the limiting plate 24 to abut against the top surface of the slide plate 11.

[0044] Each groove 13 has a first slide rod 15 horizontally slidably mounted at its bottom via a first spring 16. The end of the first slide rod 15 is hinged to the slide plate 11 via a connecting rod 14. When the first slide rod 15 slides horizontally, it pulls the slide plate 11 up and down via the connecting rod 14.

[0045] Each slide rail 13 has a fixed block 23 at its bottom, and the first slide rod 15 slides horizontally through the corresponding fixed block 23. One end of the first slide rod 15 is fixedly connected to a push plate 20, and the other end is fixedly connected to a first clamping plate 12, which corresponds vertically to the second clamping plate 25. The cooperation of the push plate 20 and the first clamping plate 12 ensures that the first slide rod 15 can only slide on the fixed block 23.

[0046] The cross-sectional shape of both the first slide bar 15 and the second slide bar 17 is rectangular.

[0047] A first spring 16 is sleeved on a first slide rod 15 between a fixed block 23 and a first clamping plate 12. One end of the first spring 16 is fixedly connected to one side of the fixed block 23, and the other end of the first spring 16 is fixedly connected to one side of the first clamping plate 12. In the initial state, the first spring 16 pushes the first clamping plate 12 to move away from the fixed block 23, so that the slide plate 11 is located at the top of the slide groove 13.

[0048] One end of the connecting rod 14 is rotatably connected to the bottom surface of the slide plate 11, and the other end of the connecting rod 14 is rotatably connected to the top of the push plate 20.

[0049] Working principle:

[0050] In use, the welding machine is fixed on top of base 1. The main component of the welding machine is a step-down transformer. The two ends of the secondary coil are the workpiece to be welded and the welding rod. During operation, an electric arc is ignited, and the welding rod is fused into the gap of the workpiece in the high temperature of the arc. The welding machine is an existing product.

[0051] Place the circuit board on top of the support plate 5. The circuit board is located between two support seats 7 within the same through slot 6, and is located below the second clamping plate 25.

[0052] When motor 8 is started, its output shaft rotates clockwise, causing lead screw 9 to rotate. Lead screw 9 drives two connecting plates 19 to slide towards each other within positioning groove 22, and connecting plates 19 move support base 7.

[0053] Bring the two support seats 7 located in the same through slot 6 closer to each other, and bring the first clamping plate 12 closer to the circuit board.

[0054] When the first clamping plate 12 moves to the side of the circuit board, the first clamping plate 12, the first slide rod 15, and the push plate 20 can no longer move. The support base 7 continues to move, which will cause the fixing block 23 to slide on the first slide rod 15 and compress the first spring 16. The first spring 16 will exert a pushing force on the first clamping plate 12, pressing the first clamping plate 12 against the circuit board, thereby fixing the circuit board.

[0055] As the support base 7 continues to move, it will cause the slide plate 11 to move, and the slide plate 11 will cause one end of the connecting rod 14 to move. The other end of the connecting rod 14 is on the push plate 20, which causes the push plate 20 to pull the slide plate 11 downward through the connecting rod 14, so that the slide plate 11 slides downward in the slide groove 13.

[0056] The slide plate 11 drives the second slide bar 17 and the second clamping plate 25 to move downwards. After the second clamping plate 25 moves to the top of the circuit board, the second clamping plate 25 and the second slide bar 17 can no longer move downwards.

[0057] The slide plate 11 slides downward outside the second slide bar 17, compressing the second spring 18. The second spring 18 exerts a pushing force on the second clamping plate 25, thereby pressing the second clamping plate 25 against the top of the circuit board. The circuit board is then fixed to the support plate 5 through the cooperation of the first clamping plate 12 and the second clamping plate 25.

[0058] After the circuit board is fixed on the support plate 5, the workers use a soldering machine to solder the pins of the circuit board. During the soldering process, the turntable 2 can be rotated, causing the worm gear 3 to rotate, which in turn drives the worm wheel 4 to rotate. The worm wheel 4 drives the rotating drum 10 and the support plate 5 to rotate, causing the circuit board to rotate, thereby making the pins that were originally difficult to solder visible and in a more convenient position for soldering.

[0059] After welding is completed, the output shaft of motor 8 reverses, driving lead screw 9 to rotate. Lead screw 9 drives two connecting plates 19 to slide back-to-back in positioning groove 22, causing the two support seats 7 in the same through groove 6 to move away from each other.

[0060] The support base 7 drives the fixing block 23 to move, the fixing block 23 drives one end of the first spring 16 to move, and the other end of the first spring 16 continues to push the first clamping plate 12 to abut against the circuit board, and the push plate 20 will not move.

[0061] The support base 7 moves the slide plate 11, and the push plate 20 pushes the slide plate 11 upward within the slide groove 13 via the connecting rod 14. The slide plate 11 moves one end of the second spring 18 upward, and the second spring 18 continues to push the second clamping plate 25 against the top of the circuit board. The slide plate 11 then moves the second clamping plate 25 to slide on the top of the circuit board.

[0062] After the first spring 16 returns to its initial state, the fixing block 23 drives the first spring 16 and the first clamping plate 12 to move, causing the first clamping plate 12 to leave the circuit board.

[0063] After the second spring 18 returns to its initial state, the slide plate 11 moves the second spring 18 and the second clamping plate 25, causing the second clamping plate 25 to leave the circuit board. The circuit board can be removed once the slide plate 11 moves to the top of the slide groove 13.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
