Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a welding tooling for manufacturing power electronic components. Background Art

[0002] The welding jig for power electronic components manufacturing is a tool or equipment used to fix electronic components in the welding process to ensure welding quality and production efficiency. The welding jig can make the welding process more stable and accurate, avoid human operation errors, thereby improving production efficiency. Moreover, the welding jig can ensure the correct positioning and connection between electronic components and welding materials, avoid quality problems such as looseness or poor contact, and ensure stable and reliable welding quality.

[0003] In the welding process of electronic components, the required electronic components are generally soldered to the required position of the circuit board by electric soldering to heat the tin wire. In the welding of small batches of products with the same specifications, the circuit board is generally placed on the welding tooling for power electronic components manufacturing, and the soldering is performed manually with a soldering iron. However, when the existing welding tooling for power electronic components manufacturing fixes the circuit board, the fixing mechanism on the tooling is difficult to ensure the fixing force when fixing the circuit board. If the fixing force is not enough, the circuit board is prone to sudden displacement, and it is impossible to accurately position the welding, resulting in welding failure. Excessive fixing force may cause damage to the circuit board. To this end, we propose a welding tooling for power electronic components manufacturing. Utility Model Content

[0028] Working principle: first, place the circuit board of the electronic components to be soldered on the carrier board 9, and make the circuit board fit with the inner wall of the concave plate 10 (the setting of the concave plate 10 facilitates the placement of the circuit board in the correct position and plays a positioning role), then rotate the handle 5, the handle 5 will drive the turntable 4 to rotate, the turntable 4 will rotate the stud 3 to rotate in the concave shell 2, the stud 3 will drive the square plate 6 to slide downward in the concave shell 2, the square plate 6 will drive the connecting plate 7 to move downward, the connecting plate 7 will drive the pressure plate 8 to move downward, the pressure plate 8 will first contact the concave plate 10, as the pressure plate 8 continues to move downward, the concave plate 10 will slide downward in the concave groove 12 on the carrier board 9, and the concave plate 10 will drive the rectangular plate 16 to move downward, the rectangular plate 16 will drive the two plug posts 17 to slide downward in the slots 19 on the respective corresponding bottom plate 1 (in this process, the two springs 18 between the rectangular plate 16 and the bottom plate 1 will be squeezed on the outer walls of the respective corresponding plug posts 17).

[0029] Then the pressing plate 8 will contact the circuit board (at this time, the upper end of the concave plate 10 is flush with the upper end of the circuit board). In order to make the circuit board more stably fixed between the pressing plate 8 and the carrier plate 9, the handle 5 can be rotated to make the pressing plate 8 move down a little, and the carrier plate 9 can also move down accordingly, and the carrier plate 9 will drive the four plugs 14 to slide down in the slots 13 on the corresponding bottom plate 1. In this process, the four springs 15 between the carrier plate 9 and the bottom plate 1 will be squeezed on the outer wall of the corresponding plugs 14. Then the handle 5 can be stopped from rotating. Relying on the force of the four springs 15, the circuit board can be fixed between the pressing plate 8 and the carrier plate 9 more stably, and the circuit board can be prevented from being damaged by excessive squeezing force. Then the electronic components can be welded on the circuit board according to the multiple positioning grooves 11 on the pressing plate 8. Similarly, when the welding is completed, the pressing plate 8 can be reset by rotating the handle 5 in the opposite direction, which is easy to operate.

[0030] It should be noted that the positioning and fixing of the circuit board by the welding tool is simple, and the fixing force is easy to control when fixing the circuit board, which not only avoids the problem of sudden displacement of the circuit board during welding due to insufficient fixing force, thereby preventing accurate positioning for welding and causing welding failure, but also avoids damage to the circuit board due to excessive fixing force.
