[0017] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.
[0018] like Figure 1~Figure 3The circuit board terminal welding fixture shown in the figure includes a base 2, the base 2 is flippable, a plurality of fixture bodies are arranged on the top of the base 2, the fixture body includes a support seat 6 for placing a circuit board 9, the support seat 6 is provided with a limiting convex wall 61 and a limiting edge 72 on opposite sides of the circuit board 9, the limiting convex wall 61 and the limiting edge 72 respectively match the edge contour of the circuit board 9, a through hole is opened in the middle of the support seat 6 near the welding area of the limiting edge 72, and the limiting edge 72 is away from the circuit board 9. One side extends to form a limit seat 7, and a plurality of terminal grooves 91 for installing terminals 92 are provided on one side of the circuit board 9 near the limit edge 72. A terminal block 62 is extended from the lower part of the limit seat 7 toward the side of the circuit board 9, and a through groove 63 is provided on the terminal block 62 corresponding to the position of the terminal 92 of the circuit board 9. A tightening block 71 that can push against the terminal 92 is provided in the through groove 63 near the limit seat 7, and a pressure plate 5 is provided on the outer side of the limit convex wall 61. The pressure plate 5 fixes the circuit board 9 with the terminal 92 on the support seat 6.
[0019] Specifically, on the through groove 63 on one side of the circuit board 9, the bent end of the "J"-shaped terminal 92 is placed into the through groove 63 of the circuit board 9, and the extended end of the terminal 92 extends out of the edge of the top of the circuit board 9 to serve as a connecting end. Then the pressing plate 5 is pressed on the top of the circuit board 9 to fix the circuit board 9 and the terminal 92 in the vertical direction. The clamping block 71 presses the terminal 92 in the horizontal direction, and the terminal 92 transmits the force to the circuit board 9, and the circuit board 9 and the terminal 92 are horizontally limited between the limiting protrusion 61 and the clamping block 71. Finally, the base 2 is flipped 180 degrees, with the bottom of the fixture body facing upward, the bottom of the circuit board 9 facing upward, and the "J"-shaped embedded bent end of the terminal 92 is welded and fixed to the circuit board 9.
[0020] The bottom of the pressing plate 5 is hinged on the support seat 6, and a clamping seat 8 is provided on the outer side of the limiting seat 7 facing the pressing plate 5. The bottom of the clamping seat 8 is hinged on the base 2. The pressing plate 5 can be rotated toward the circuit board 9 to press on the top of the circuit board 9. The clamping seat 8 is rotated and adjusted, and the clamping portion of the clamping seat 8 extending horizontally toward the pressing plate 5 presses the free end of the pressing plate 5 on the bottom. After the clamping seat 8 presses the pressing plate 5 on the top of the circuit board 9, the pressing plate 5 is locked, so that when the base 2 drives the clamp body to flip downward, the pressing plate 5 will not be separated. The bottom of the pressing plate 5 and the clamping seat 8 are hinged, so that the pressing plate 5 can be turned over and closed. The clamping seat 8 has a certain range of motion, which can make the horizontal extension of the clamping seat 8 press low on the top of the pressing plate 5.

The pressing blocks 52 abut and fix the circuit board 9 in the vertical direction, and the convex point 51 on the pressing plate 5 corresponding to the terminal 92 is pressed on the top of the terminal 92 to ensure that the terminal 92 is stable and immovable during welding.
[0023] Further, each abutting block 71 is fixedly connected to the telescopic end of the ejection cylinder 4 horizontally penetrating the limit seat 7, and multiple ejection cylinders 4 are distributed on the base 2 at positions corresponding to the abutting blocks 71. Each ejection cylinder 4 is connected to the abutting block 71, serving as the power of the abutting block 71.
[0024] In addition, two clamp bodies are evenly distributed on the base 2, and a through hole is opened in the bottom welding area of the clamp body on the base 2.
[0025] The working process of the utility model is as follows:
[0026] As shown in Figures 1-3, first, place the circuit board 9 on the support seat 6 in the appropriate direction, then place the terminals 92 into the terminal slots 91 in turn, put down the pressure plate 5, and the clamping seat 8 will limit the pressure plate 5, extend the ejector cylinder 4, and the clamping block 71 will abut on the edge of the terminal 92. Finally, rotate the cylinder 3 to flip the base 2 so that the bottom of the fixture body faces upward, and weld the terminal 92.
[0027] The above embodiments are only illustrative of the principles and effects of the invention of the utility model, as well as some embodiments of its application, and are not intended to limit the invention of the utility model.
