Description

Technical Field

[0001] The utility model relates to the technical field of capacitor processing, in particular to a welding device for processing stacked solid-state capacitors. Background Art

[0002] The structure of the stacked solid capacitor is shown in the attached figure. Figure 1 As shown, it includes a positive electrode part and a negative electrode part, wherein multiple layers of negative electrode parts are stacked in sequence on the horizontal plate of the negative electrode part, and a positive electrode part is provided at the front end of the negative electrode part of each layer. The upper and lower positive electrode parts are connected by a welding plate, and a welding point is provided at the connection between the positive electrode part and the welding plate.

[0003] The welding process for stacked solid-state capacitors requires manual layer-by-layer welding. After the first layer is spot-welded, the second layer is stacked on top, and so on. This method of operation is inefficient and requires workers to hold the positive electrode to maintain its levelness during welding. Even the slightest tilt of the positive electrode can affect the quality of the stacked capacitor. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Common stacked solid capacitors are shown in the following Figure 1 As shown, the capacitor comprises a positive electrode portion and a negative electrode portion. Several layers of positive electrode portions 13 and negative electrode portions 16 are provided on the positive and negative electrode portions. The positive electrode portions 13 and negative electrode portions 16 on the same layer form a capacitor unit. The positive electrode portions 13 and negative electrode portions 16 on the same layer are connected by insulating material to form a whole. During welding, the upper and lower layers of positive electrode portions 13 are connected by welding plates 14 and fixed using a welding gun 15.

[0024] In this embodiment, refer to Figure 1-3 A welding device for processing stacked solid-state capacitors includes a mounting frame 1, a multi-layer platform extending outward from the side of the mounting frame 1, an extension platform 4 is provided at the end of the platform, a first sliding plate 5 is slidably installed on the central axis of the table top of the extension platform 4, and second sliding plates 9 that maintain a symmetrical relationship are slidably installed on both sides of the table top of the extension platform 4, and the two second sliding plates 9 maintain a vertical relationship.

[0025] Combined with attachment Figure 2 And attached Figure 3 It can be seen that a cylinder 2 is provided on the mounting frame 1, and a vertical plate 3 is provided at the front end of the pneumatic rod provided at the output end of the cylinder 2. The vertical plates 3 are respectively connected to the rear ends of the first sliding plates 5 of each layer.

[0026] Here, the mounting frame 1 and the platforms of each layer form an integrated structure, and the platforms of each layer are provided with notches for the vertical plates 3 to move back and forth.

[0027] The contents that need to be explained in detail are as follows: Figure 2 As shown, the angle between the two second sliding plates 9 is a right angle, and the first sliding plate 5 is located on the angle bisector of the right angle.

[0028] In order to ensure the sliding stability of the first sliding plate 5 and the second sliding plate 9, a first guide platform 7 and two second guide platforms 8 are respectively provided on the table surface of the extension platform 4. The first sliding plate 5 slides linearly in the first guide platform 7, and the second sliding plate 9 slides linearly in their respective second guide platforms 8.

[0029] A first rack arm 51 is provided at the front end of the first sliding plate 5, and a second rack arm 91 is provided at the front end of each of the two second sliding plates 9. A gear 6 is provided between the adjacent first rack arms 51 and second rack arms 91 on the table surface of the extension platform 4 to maintain meshing transmission with the two.

[0030] The specific transmission process is as follows: the cylinder 2 pushes or pulls the first sliding plate 5 of each layer to slide, and the first rack arm 51 at the front end of the first sliding plate 5 engages with the two gears 6, thereby controlling the corresponding sliding of the two second rack arms 91. At this time, the two second rack arms 91 slide in the same direction, sliding forward or backward synchronously.

[0031] The front ends of the second rack arms 91 are each provided with an extension arm 10. The adjacent inner surfaces of the two extension arms 10 are each provided with a plurality of cushioning pads 11. The front ends of the extension arms 10 are each provided with a limit block 12. The frame structure formed by the two extension arms 10 and the two limit blocks 12 is used to accommodate the positive electrode portion 13 of the stacked solid-state capacitor to be welded.

[0032] When placing the positive electrode part 13, the two extension arms 10 are first controlled by the cylinder 2 to slide forward at the same time. At this time, the frame area used to accommodate the positive electrode part 13 gradually expands, making it convenient for workers to place the positive electrode part 13 therein; after the positive electrode part 13 is placed firmly, the two extension arms 10 are controlled by the cylinder 2 to slide backward at the same time. At this time, the frame area used to accommodate the positive electrode part 13 gradually shrinks until it just clamps the positive electrode part 13. Therefore, the positive electrode parts 13 of the upper and lower layers are in a relatively stable position, and the welding plate 14 is placed therein, and then it can be welded and fixed using the welding gun 15.

[0033] Compared to traditional layer-by-layer welding of positive electrode portions 13, this solution positions each layer of positive electrode portions 13 simultaneously, reducing welding time. All positive electrode portions 13 can be welded while remaining horizontal, resulting in a better forming effect. Once forming is complete, the positive electrode portions 13 can be released by loosening the extension arm 10, making the process more convenient.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
