Description

TECHNICAL FIELD

[0001] The utility model belongs to the pin welding technical field, concretely relates to a power pin welding tool. BACKGROUND

[0002] The original pin needs to be installed on the PCB board one by one and then welded. Artificial installation of the pin is large in workload, time-consuming, low in work efficiency, and the pin is easy to be inclined and uneven in spacing when being installed one by one, and the welding height is easy to be not uniform when the PCB board is fixed by hand or the pin is fixed.

[0003] The Chinese patent with the application number 202221505201.3 discloses a PCB pin welding tool for reflow soldering equipment, which is to first wrap the PCB board on the PCB fixing column 4 on the adjusting mounting plate, then insert the pin into the pin hole on the PCB board, and set the blind hole corresponding to the pin hole on the PCB board on the adjusting mounting plate. This structure of first installing or fixing the PCB board and then inserting the pin is not applicable to the pin with a limiting boss.

[0004] The Chinese patent with the application number 202220422796.X discloses a pin quick welding tool, which is to fix the pin to be welded in the corresponding hole in the PCB board tool, align the PCB board hole with the pin and put down and apply soldering paste; then put the PCB board and the PCB board tool into the square groove of the quick clamping tool base, then place the heating module on the upper surface of the base and power on the heating module to melt the soldering paste. In the case of a large number of pins, it is difficult to align one by one when the PCB board hole is aligned with the pin. SUMMARY

[0005] In view of the above problems existing in the prior art, the utility model provides a power pin welding tool.

[0006] The utility model discloses a power pin welding tool, which comprises a first bottom plate and a second bottom plate, the first bottom plate is connected with the second bottom plate through bolts, and the distance between the first bottom plate and the second bottom plate is adjusted, at least one PCB board containing groove is arranged on the first bottom plate, pin holes are distributed in the PCB board containing groove, and PCB board positioning columns are arranged on the edge of the PCB board containing groove.

[0007] Two PCB board containing grooves are arranged on the first bottom plate.

[0008] A groove penetrating through the first bottom plate is further arranged on the first bottom plate.

[0009] Compared with the prior art, the utility model discloses the one end of all the pins is inserted into the pin hole of first bottom plate, then the PCB board is placed on the pin, the PCB board is positioned through the PCB board positioning column, then the other end of pin is completely inserted into the hole on the PCB board under pressure, finally the integral welding is carried out, the insertion depth of pin is uniform, the welding efficiency is high, the welding effect is excellent, and it is suitable for different length, and the pin with limiting boss. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is the structure schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] The utility model is further explained below in combination with the drawings and specific embodiments. It should be understood that these embodiments are only used for illustrating the utility model, and are not used for limiting the scope of the utility model, and after reading the content of the utility model, the person skilled in the art can make various changes or modifications to the utility model, and these equivalent forms are also in the range defined by the utility model.

[0012] As Figure 1 The utility model discloses a power pin welding tool, including first bottom plate 1 and second bottom plate 5, first bottom plate 1 and second bottom plate 5 around set screw hole 6, screw hole 6 is inserted into the bolt, and first bottom plate 1 and second bottom plate 5 are connected through the bolt, and the spacing between first bottom plate 1 and second bottom plate 5 is adjusted through the screwing depth of the bolt to adapt to the pin of different length. At least one PCB board containing groove 2 is arranged on first bottom plate 1, and the pin hole 4 is distributed in PCB board containing groove 2, and the pin hole 4 on first bottom plate 1 corresponds to the pin hole position on the PCB board, and the PCB board positioning column 3 is arranged on the edge in PCB board containing groove 2.
