Description

Technical Field

[0001] The utility model relates to the technical field of processing jigs, in particular to a jig for capacitor processing. Background Technique

[0002] A capacitor is a device that stores electric charge and is one of the electronic components widely used in electronic devices. It is widely applied in aspects such as DC blocking and AC passing, coupling, bypassing, filtering, tuning circuits, control, etc. in circuits. The basic working principle of a capacitor is to use the electric field between two conductors to store electric charge. When a voltage is applied across the two ends of the capacitor, positive and negative charges will accumulate on the two conductors respectively, thus forming an electric field between the conductors. The energy of the electric field is stored in the capacitor. When the voltage across the two ends of the capacitor disappears, the capacitor will release the stored charge. The capacitance of a capacitor is a physical quantity that measures its ability to store electric charge. The magnitude of the capacitance is related to factors such as the structure, material, and applied voltage of the capacitor. Generally speaking, the larger the capacitance of the capacitor, the stronger its ability to store electric charge.

[0003] A capacitor processing jig usually consists of the following main parts: The fixed base is the basic part of the jig, which provides stable support for the entire jig. The clamping bolt is one of the main components of the clamping mechanism. The clamping bolt usually adopts a high-strength threaded connection to ensure the stability and reliability of the clamping force. The clamping block is in direct contact with the capacitor and transmits the clamping force to the capacitor. The shape and material of the clamping block are selected according to the surface shape and material of the capacitor to avoid damaging the capacitor. In some jigs, a clamping spring is used to provide additional clamping force. The clamping spring can keep the clamping block in a certain clamping state when the clamping bolt is loosened, preventing the capacitor from loosening accidentally. At the same time, the clamping spring can also play a buffering role, reducing the impact on the capacitor during the clamping process. The guide post is used to guide the moving parts of the jig to ensure the accurate opening, closing, and clamping actions of the jig. The protective cover can protect the capacitor from external impurities and damage during the processing. The protective cover is usually made of a transparent material so that the operator can observe the processing situation of the capacitor. The protective cover can be connected to the jig through hinges, buckles, etc., for convenient opening and closing.

[0004] In the current capacitor processing process, there are obvious drawbacks. Firstly, the clamping operation of the capacitor mainly relies on manual labor to load and unload and clamp the blank. This method is not only extremely time-consuming and laborious, but also seriously reduces the production efficiency of capacitor processing. Workers need to operate each capacitor one by one, consuming a large amount of time and energy. Moreover, the speed and stability of manual operation are limited, making it difficult to meet the needs of large-scale production. Secondly, the welding angle of the capacitor's sealing cover is not convenient to adjust. In actual processing, different capacitors may require different welding angles. However, the existing processing methods are difficult to flexibly adjust the welding angle of the sealing cover, which brings great trouble to the processing process, may lead to unstable welding quality, and affect the performance and reliability of the capacitor. Summary of the Invention

Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figure 1 andFigure 3 , an embodiment provided by the present utility model: A fixture for capacitor processing, including a base 1, a rotating seat 2 is fixedly connected to the middle of the top end of the base 1, a rotating shaft 3 is rotatably connected inside the rotating seat 2, a rotating gear disk 6 is fixedly connected to the bottom of the outside of the rotating shaft 3, telescopic cylinders 7 are fixedly connected to the front and rear sides of the top end of the rotating shaft 3, a telescopic rod 8 is slidably connected to the middle of the inside of the telescopic cylinder 7, a clamping seat 9 is fixedly connected to the middle of the rear end of the front telescopic rod 8, and the telescopic cylinder 7 pushes the clamping seat 9 on the telescopic rod 8 to clamp the capacitor blank. The rotating gear 5 on the rotating motor 4 drives the rotating gear disk 6 on the rotating shaft 3 to rotate uniformly on the rotating seat 2 on the base 1, so that the sealing cover on the capacitor blank can be precisely and uniformly welded by a laser welding machine, improving the production quality of the capacitor.

[0027] Refer to Figure 1 - Figure 2 , a support 14 is fixedly connected to the rear part of the left end of the base 1, a baffle 16 is fixedly connected to the top end of the support 14, a feed pipe 15 is fixedly connected to the front side of the bottom end of the baffle 16, a fixed frame 19 is fixedly connected to the left end of the support 14, a tray motor 20 is fixedly connected to the middle of the top end of the fixed frame 19, a rotating tray 18 is rotatably connected to the middle of the bottom end of the tray motor 20, and rotating feed pipes 17 are fixedly connected to the four corners of the bottom end of the rotating tray 18. By driving the rotating tray 18 to rotate continuously by the tray motor 20, the capacitor blanks in the feed pipe 21 continuously fall into the rotating feed pipes 17 on the rotating tray 18, and then the capacitor blanks are uniformly conveyed into the feed pipe 15 according to the rotation speed. Subsequently, the feed pipe 15 drops the capacitor blanks into the guide groove 13, and the capacitor blanks accurately fall on the clamping seat 9 under the guidance of the guide groove 13.

[0028] Refer to Figure 1 - Figure 3 , columns 11 are fixedly connected to the four corners of the top end of the base 1, a top plate 12 is fixedly connected to the top ends of the columns 11, a guide groove 13 is fixedly connected to the middle of the bottom end of the top plate 12, a rotating motor 4 is fixedly connected to the middle of the right side of the bottom end of the base 1, a rotating gear 5 is rotatably connected to the middle of the top end of the rotating motor 4, blanking holes are provided in the middle of the rotating shaft 3 and the top end of the base 1, a feed pipe 21 is fixedly connected to the front side of the top end of the fixed frame 19, and a plurality of fixed rubber rings 10 are equidistantly arranged from top to bottom inside the clamping seat 9. Workers convey the capacitor blanks into the feed pipe 21 through a feeding device. To prevent damage to the blanks due to excessive clamping, the fixed rubber rings 10 inside the clamping seat 9 are used for buffering when clamping the blanks. Subsequently, the capacitor sealing cover is used to seal the top of the blank by a manipulator.

[0029] Working principle: The worker conveys the capacitor blank to the material conveying pipe 21 through the feeding device. Then, the rotating disk 18 is driven by the disk motor 20 to rotate continuously, so that the capacitor blanks in the material conveying pipe 21 continuously fall into the rotating material pipe 17 on the rotating disk 18. Then, the capacitor blanks are evenly conveyed into the feeding pipe 15 according to the rotation speed. Subsequently, the feeding pipe 15 drops the capacitor blanks into the guiding groove 13.

Subsequently, the telescopic cylinder 7 pushes the clamping seat 9 on the telescopic rod 8 to clamp the capacitor blank. To prevent over-clamping from damaging the blank, the fixed rubber ring 10 in the clamping seat 9 is used for the buffering of blank clamping. Then, the capacitor sealing cover is used by the manipulator to seal the top of the blank. Then, the rotating gear 5 on the rotating motor 4 drives the rotating tooth disk 6 on the rotating shaft 3 to rotate evenly on the rotating seat 2 on the base 1, so that the sealing cover on the capacitor blank can be precisely and evenly welded by the laser welder, improving the production quality of the capacitor.
