[0047] See attached document Figure 1This application provides a circuit board welding apparatus, including a worktable 1, a welding mechanism 2, a moving mechanism 3, and a clamping fixture 4. The welding mechanism 2 is mounted on the worktable 1 and moves along the length and thickness directions of the worktable 1 to facilitate welding of the circuit board. The moving mechanism 3 is slidably mounted on the worktable 1 and moves along the width direction of the worktable 1. The clamping fixture 4 is mounted on the moving mechanism 3 and includes a workpiece platform 401 and clamping mechanisms symmetrically arranged at both ends of the workpiece platform 401. The clamping mechanisms can automatically move towards the center of the workpiece platform 401 to clamp the circuit board placed on the workpiece platform 401.

[0048] Specifically:

[0049] like Figure 1 As shown, the welding mechanism 2 includes a support 201, a first lead screw module 202, a fixed frame 203, a second lead screw module 204, a welding machine frame 205, and a welding machine 206. The support 201 and fixed frame 203 are mounted on the worktable 1. The first lead screw module 202 is horizontally positioned between the supports 201. The fixed frame 203 is slidably mounted on the first lead screw module 202 and reciprocates on the support 201 via the first lead screw module 202. The second lead screw module 204 is vertically mounted on the fixed frame 203. The welding machine frame 205 is slidably mounted on the second lead screw module 204. The welding machine 206 is fixedly mounted on the welding machine frame 205. The second lead screw module 204 drives the welding machine 206 and the welding machine frame 205 to rise or fall along the thickness direction of the worktable 1.

[0050] In the above description, the moving mechanism 33 includes two slide rails 301, a third lead screw module 302, and a slide table 303. The two slide rails 301 are fixedly installed on the worktable 1 and are spaced apart on the worktable 1, with the guide rails arranged along the width direction of the worktable 1. The third lead screw module 302 is located between the two slide rails 301 and is arranged along the width direction of the worktable 1. A threaded sliding sleeve that mates with the third lead screw module 302 is provided in the middle of the slide table 303. T-shaped sliding seats that mate with the slide rails 301 are provided at both ends of the slide table 303. The clamping fixture 4 is set on the slide table 303. The third lead screw module 302 drives the slide table 303 to move along the width direction of the worktable 1, so that the clamping fixture 4 moves with the slide table 303. The circuit board is clamped on the clamping fixture 4 and moves together with the slide table 303 during circuit board soldering, so that the soldering machine 206 can solder the required soldering position of the circuit board.

[0051] In this embodiment, as Figures 2 to 4As shown, the clamping operation includes a workpiece platform 401. The workpiece platform 401 has clamping mechanisms symmetrically arranged at both ends along its length. Specifically, the clamping mechanisms include a boss 402, a limiting slider 406, a push plate 404, an electric push rod 405, a limiting slider 406, and a guide push block. The boss 402 is integrally formed on both ends of the workpiece platform 401, and a groove is provided along the length of the boss 402. The groove is connected to the center side of the workpiece platform 401. The limiting slide plate 403 is attached to the groove and can extend and retract from the groove at the center end of the workpiece platform 401. The limiting slide plate 403 has an inclined surface on the side away from the center of the workpiece platform 401. A push plate 404 is provided on the inclined surface. The push plate 404 has a triangular structure and is attached to the inclined surface of the limiting slide plate 403. An electric push rod 405 is provided at the outer end of the boss 402 along the length direction. The output end of the electric push rod 405 passes through the groove and is fixed to the push plate 404. The extension of the electric push rod 405 drives the push plate 404 to move along the length direction of the groove. Thus, the push plate 404 contacts the inclined surface of the limiting slide plate 403, so that the push plate 404 pushes the limiting slide plate 403 out of the groove. Of course, in order for the limiting slide plate 403 to return to its original position and retract into the groove after the electric push rod 405 retracts, such as Figure 5 As shown, a first spring 408 is provided in the groove, and the first spring 408 is used to pull the extended limiting slide plate 403 back into the groove.

[0052] Furthermore, the limiting slide plate 403 is provided with a groove along the length direction on the plate surface on one side of the center of the workpiece platform 401. The limiting slider 406 is slidably disposed at both ends of the groove and is symmetrically arranged. The groove is a T-shaped groove and the limiting slider 406 is a T-shaped slider, forming a limiting fit to prevent the limiting slider 406 from falling off. The side of the limiting slider 406 facing away from the center of the workpiece stage 401 is set as an inclined surface. A guide push block fixed to the workpiece stage 401 is set on one side of the inclined surface of the limiting slider 406. The guide push block has an inclined surface that fits against the limiting slider 406. It can be imagined that when the limiting slide plate 403 is pushed out of the groove and moves towards the center of the workpiece stage 401, the limiting slider 406 is pushed along the length of the groove towards the limiting slider 406 on the opposite side due to the contact with the inclined surface of the guide push block. As the electric push rod 405 extends continuously, the limiting slide plates 403 on both sides and the limiting sliders 406 at the four corners move closer to the center of the workpiece stage 401. Thus, when clamping, the circuit board only needs to be placed on the workpiece stage 401, and the circuit board can be automatically clamped on the workpiece stage 401 by using the synchronous movement of the clamping mechanisms on both sides.

[0053] Of course, in the above, in order for the limiting slider 406 to return to both ends of the limiting slide plate 403 after clamping is completed, as follows: Figure 5As shown, a second spring 409 is provided in the slide groove. The second spring 409 applies a pulling force to the limiting slider 406, pulling the closing limiting slider 406 back to both ends of the limiting slide plate 403.

[0054] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
