[0002] The water pump controller is a key component in the water pump system, responsible for controlling the start, stop, and operating status of the water pump. Traditionally, the manufacturing process for water pump controllers involves soldering the aluminum substrate to the circuit board, and finally soldering the three signal lines to the pins on the circuit board. This soldering process typically requires manual operation, which is not only inefficient but also difficult to ensure soldering quality. Problems such as cold and dry solder joints can easily occur, impacting the stability and reliability of the controller. Utility Model Content

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 The water pump controller circuit board flip welding device shown includes:

[0022] A base plate 1, with hinged ears 2 fixed on both sides of the base plate 1, and support legs 21 fixed below the base plate;

[0023] A flip plate 3, the flip plate 3 is hingedly connected between the hinged ears 2, the flip plate 3 is provided with a circuit board positioning groove 4, the circuit board positioning groove 4 is provided with a first clearance groove 5, and a pressing mechanism is fixed on the flip plate 3;

[0024] A support assembly is fixed below the flip plate 3 and includes two first support rods 6 , a support plate 7 is fixed below the support rods, and a plurality of snap-in grooves 8 are provided on the outer side of the support plate 7 .

[0025] The process of using the present invention is as follows: the welding device is placed on the welding platform through the support legs 21. Since the flip plate 3 is hingedly connected to the base plate 1, when the water pump controller circuit board needs to be welded, the flip plate 3 remains in the state supported by the support assembly, and then the circuit board is placed in the circuit board positioning groove 4, and the aluminum substrate 20 is passed through the welding holes on the circuit board 19 through the pins thereon. Finally, the aluminum substrate 20 and the circuit board 19 are pressed together by the clamping mechanism, and then the three signal lines are clamped in the clamping groove 8 of the support plate 7 so that the terminal ends of the signal lines are near the bottom pins of the circuit board 19. Finally, the circuit board 19 is flipped and rotated 180 degrees. At this time, the back of the circuit board 19 is facing upward, and the pins of the aluminum substrate 20 are welded to the circuit board 19 by the welding device. At the same time, the flip plate 3 on the signal line is flipped first, and the circuit board is connected to the circuit board positioning groove of the flip plate 3. Then the terminal is welded to the pins of the circuit board. Finally, the flip plate 3 is flipped again, the clamping mechanism is released, and the welded circuit board is removed.

[0026] Furthermore, two second support rods 9 are fixed to the rear side of the base plate 1. When the flip plate 3 flips, the second support rods 9 keep the flip plate 3 horizontal. Specifically, in order to keep the flip plate 3 horizontal after flipping, two second support rods 9 are fixed to the rear side of the base plate 1 to facilitate welding with a welding gun.

[0027] Furthermore, the clamping mechanism includes a first clamping seat 10, a second clamping seat 11 and a clamping plate 12. The first clamping seat 10 and the second clamping seat 11 both include a seat body 13. The seat body 13 is provided with a positioning step 14. A positioning protrusion 15 is fixed on the positioning step 14. A limit block 16 is rotatably connected to the top of the positioning protrusion 15. A clamping groove 8 is provided on both sides of the clamping plate 12. When positioning the circuit board, the positioning protrusion 15 is located in the clamping groove 8. Specifically, the clamping mechanism of the present invention includes two clamping seats. The clamping plate 12 can be connected above the clamping seat. The positioning groove on the clamping plate just matches the positioning protrusion 15. When the clamping plate 12 is connected, the limit block 16 on the top of the positioning protrusion 15 starts to rotate. When the limit block 16 rotates, the clamping plate 12 can be limited so that it cannot move in the vertical direction, thereby achieving the positioning of the circuit board.

[0028] Furthermore, the bottom plate 1 is provided with a second clearance groove 17 below the support plate 7. Specifically, the bottom plate 1 of the present invention is provided with a second clearance groove 17 on the support plate 7, so that when positioning the signal line, the signal line can pass upward from the second clearance groove 17, which is more convenient when positioning.

[0029] Furthermore, a weight-reducing hole 18 is provided in the rear area of the bottom plate 1. Specifically, the present invention has a weight-reducing hole 18 in the rear area of the bottom plate 1, which makes the weight lighter and can be directly lifted when the bottom plate 1 is moved.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
