Description

Technical Field

[0001] The utility model relates to the technical field of spot welding head cleaning, in particular to a welding head cleaning device. Background Art

[0002] As a basic electronic component, power inductors are widely used in various electronic devices or electronic control circuits. Currently, various electronic devices are developing in the direction of miniaturization, lightness, and multi-functions. The number of power inductors used is increasing, but at the same time, new requirements for power inductors such as miniaturization, low installation thickness, and large inductance are also put forward.

[0003] The preparation process of power inductors usually includes prefabricated magnetic cores, winding, powder filling and pressing. The winding process is generally a process of winding enameled wire on a prefabricated T-shaped or I-shaped magnetic core by a winding machine. After winding the enameled wire on the columnar protrusion of the magnetic core, the end of the enameled wire needs to be folded to the flat area of ​​the magnetic core, and the folded enameled wire end is welded and attached to the flat surface by a spot welding mechanism, thereby completing the winding process. However, the following problems exist in the prior art:

[0004] The spot welding head of the spot welding mechanism will directly contact the insulating layer of the outer layer of the enameled wire during the spot welding process. Since the spot welding head has a certain temperature, a small amount of insulating layer will adhere to it during contact. The spot welding head needs to be cleaned with a cleaning brush. Usually, the cleaning brush is fixed at a certain position on the side of the spot welding mechanism, which will cause the contact position between the spot welding head and the cleaning brush to be concentrated in a single area on the surface of the cleaning brush. As the number of cleaning times increases, the cleaning effect becomes worse and worse, which eventually leads to a decrease in spot welding quality and a lower product qualification rate.

[0005] Therefore, it is urgent to design a structure that can solve the above problems. Utility Model Content

The head of the second shaft 51 extending out of the second convex ring 53 is clamped in the tooth groove 411.

[0033] Among them, in this embodiment, in order to realize the elastic effect of the first spring 46, one end of the first spring 46 is against the first convex ring 47, and the other end of the first spring 46 can be against the upper end surface of the first fixed block 42.

[0034] Optionally, the sliding mechanism includes a slide 32 and a slide rail 31, the slide rail 31 is mounted on the frame 1, the slide 32 is slidably mounted on the slide rail 31, the cleaning brush 2 is mounted on one end of the slide 32, and the card slot block 41 is mounted on the other end of the slide 32. Figure 1 As shown, the cleaning brush 2 is mounted on the upper end of the slide 32 , and the slot block 41 is mounted on the lower end of the slide 32 .

[0035] Furthermore, it also includes an elastic member, one end of which is mounted on the slide rail 31, and the other end of which is mounted on the slide table 32, and the length direction of the elastic member is parallel to the sliding direction of the slide table 32, wherein the elastic member is mounted on the end of the slide rail 31 away from the driving member. Figure 1 As shown, the elastic member is installed at the left end of the slide rail 31, and the driving member is installed at the right end of the frame 1, and the second groove surface 4112 is located at one end close to the driving member. Such a configuration has the beneficial effect that the first elastic component and the second elastic component can limit the slide 32 from sliding to the left, and the elastic member can limit the slide 32 from sliding to the right, thereby ensuring that the position of the cleaning brush 2 during use remains relatively stable. Optionally, the elastic member can be a third spring 33.

[0036] Specifically, in this embodiment, the driving mechanism is arranged below the sliding mechanism to provide a power source for the movement of the cleaning brush 2 above the sliding mechanism.

We can see that the replacement here is one tooth groove 411 for one tooth groove 411 , and the distance of each replacement is the spacing of one tooth groove 411 .

[0037] The utility model provides a welding head cleaning device, in which a driving part drives a first elastic component to replace a tooth groove 411, and then pulls the slot block 41 to move, thereby driving a slide 32 and a cleaning brush 2 on the slide 32 to move, thereby improving the adjustability of the cleaning surface of the cleaning brush 2, avoiding the problem of poor cleaning effect caused by the welding head contacting a single cleaning area for a long time, thereby improving the spot welding quality and the qualified rate of the product, and the overall structure of the mechanism is simple and easy to operate.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
