Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Combination Figures 1-6 A capacitor welding device for a water purifier motherboard includes a base plate 1, and a positioning mechanism 2, a bending mechanism 3 and a welding mechanism 4 are provided at the top of the base plate 1.

[0027] See Figure 2 and Figure 3Furthermore, the positioning mechanism 2 includes a fixing ring 201 fixedly connected to the middle of the top of the base plate 1. A fixing frame 202 is fixedly connected to the outer side of the fixing ring 201 at the top of the base plate 1. Positioning rods 203 are symmetrically fixedly connected to the four ends of the fixing frame 202. The four sets of positioning rods 203 are L-shaped. A water purifier main board body 204 is provided at the top of the fixing frame 202. The water purifier main board body 204 is in contact with the positioning rods 203. A water purifier capacitor 205 is provided on the inner wall of the fixing ring 201. Pins 206 are fixedly connected to both sides of the top of the water purifier capacitor 205 and pass through the water purifier main board body 204.

[0028] Specifically, the fixing ring 201 can limit the placement of the water purifier capacitor 205, the fixing frame 202 is used to place the water purifier main board body 204, and the positioning rod 203 is used to position the water purifier main board body 204, so that the pin 206 is exactly below the welding gun 404, thereby facilitating fast welding and improving welding efficiency.

[0029] Example 2

[0030] See Figure 4 and Figure 5 Furthermore, based on Embodiment 1, the bending mechanism 3 includes upright plates 301 fixedly connected to both sides of the fixed frame 202 at the top of the base plate 1. Two sets of upright plates 301 are provided with guide grooves 302 at one end close to each other. Bending frames 303 are provided between the two sets of upright plates 301. Guide posts 304 are fixedly connected to both ends of the two bending frames 303. The two sets of guide posts 304 are respectively set in the guide grooves 302. Fixed plates 305 are fixedly connected between the two sets of upright plates 301. Electric push rods 306 are fixedly connected to the top of the two fixed plates 305. Slider 307 is fixedly connected to the telescopic ends of the two electric push rods 306. The two sliders 307 and the two bending frames 303 are slidably connected. The upright plates 301 are symmetrically distributed about the center line of the base plate 1. The upper half of the guide groove 302 is set vertically and the lower half is set inclined.

[0031] Specifically, the guide post 304 is limited by the guide groove 302 and can only move within the guide groove 302. When the guide post 304 moves to the inclined part of the guide groove 302, the bending frame 303 tilts and moves, thereby bending the pin 206, which increases the welding area and improves the welding stability. The electric push rod 306 moves the bending frame 303 down and the slider 307 slides on the bending frame 303.

[0032] Example 3

[0033] See Figure 1 and Figure 6Furthermore, based on Embodiment 1 and Embodiment 2, the welding mechanism 4 includes a fixed frame 401 fixedly connected to the top of the base plate 1 corresponding to the outside of the fixed frame 202. A linear motor 402 is fixedly connected to the top of the inner wall of the fixed frame 401. An electric telescopic rod 403 is fixedly connected to the driving end of the linear motor 402. A welding gun 404 is fixedly connected to the telescopic end of the electric telescopic rod 403. The center line of the pin 206 and the travel path of the welding gun 404 are on the same vertical plane.

[0034] Specifically, the linear motor 402 moves the electric telescopic rod 403, which in turn moves the welding gun 404 toward the pin 206 and performs welding operations on the pin.

[0035] In actual operation, firstly, the pins 206 on the water purifier capacitor 205 are passed through the holes on the main body 204 of the water purifier. Then, under the positioning action of the positioning rod 203, the main body 204 of the water purifier can be positioned, and the water purifier capacitor 205 is placed in the fixing ring 201. Therefore, the placement can be completed quickly, reducing the number of adjustments, thereby quickly completing the welding operation and improving welding efficiency.

[0036] The electric push rod 306 is activated, which moves the slider 307 downward. When the guide post 304 moves to the bend of the guide groove 302, the bending frame 303 just contacts the upper part of the middle of the pin 206. As the bending frame 303 continues to move downward, the guide post 304 moves obliquely under the action of the guide groove 302. At this time, the bending frame 303 also moves away from the pin, which can increase the welding area and thus improve the welding stability.

[0037] Then, the electric telescopic rod 403 is activated to make the welding gun 404 contact the pin 206. At this time, the linear motor 402 is activated to move the electric telescopic rod 403 and perform welding operation on the pin 206.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
