[0037] Equipment bracket body 1;

[0038] An automatic transmission track 2, fixedly arranged on the equipment support body 1, for placing and transmitting the capacitor core;

[0039] An automatic flipping mechanism 3 is rotatably connected to the equipment support body 1, and flips the capacitor core when the capacitor core reaches a predetermined position;

[0040] The lower electrode 4 is fixedly arranged on the equipment support body 1, and the connecting piece is placed on the lower electrode 4;

[0041] A clamping mechanism 5, one end of which is fixedly disposed on the equipment support body 1, and when the connecting piece is placed on the lower electrode 4, the clamping mechanism 5 is switched to a locking state to fix the connecting piece;

[0042] A driving module 6 is slidably fixed on the equipment support body 1;

[0043] One end of the welding mechanism 7 is fixedly connected to the driving module 6. The welding mechanism 7 is provided with an upper electrode. When the capacitor core is turned over and the connecting piece is fixed, the welding mechanism 7 welds the core fuse to the connecting piece through the upper electrode.

[0044] The technical solution of this embodiment realizes the continuous and efficient transportation and positioning of the capacitor core through the automated transmission track and turnover mechanism. Compared with the traditional manual operation method, this automated process significantly improves the operation speed and overall efficiency of the production line. The high-precision welding mechanism 7 and the upper electrode are used to ensure the welding quality between the core fuse and the connecting piece. The automated welding process reduces the error caused by human factors, making the welding point more uniform and firm, thereby improving the qualified rate of the product.

[0045] Preferably, the welding equipment further comprises an image acquisition device 8, which is fixedly mounted on the driving module 6 and is connected to a host system signal. When reaching a predetermined position, the image acquisition device 8 sends the acquired image data to the host system.

[0046] The technical solution of this embodiment collects image data of the connecting piece and the core fuse through the image acquisition device 8, thereby realizing production visualization and improving production efficiency.

[0047] Preferably, the image acquisition device 8 sends the acquired image data to the host system, the image data at least including the core fuse shape data and the core fuse coordinate data, and the host system controls the welding mechanism 7 to weld a preset distance from the end of the core fuse.

[0048] In the technical solution of this embodiment, the power capacitor core is transferred to a predetermined position by the automatic transmission track 2 and the automatic turning mechanism 3, the connecting piece placed on the lower electrode 4 is pressed and fixed by the pressing mechanism 5, and then the image data is collected by the image acquisition device 8, see Figure 3 The image acquisition device 8 or the host system can obtain the data of the core fuse in the image data collected by the image acquisition device. The host system can obtain the shape and coordinate data of each core fuse according to the image data, and drive the welding mechanism 7 to weld the preset length along the extension direction of the fuse from the position starting from the end of the core fuse, thereby realizing the automatic welding of the core fuse of the power capacitor and the connecting piece, greatly saving labor costs and greatly improving the welding accuracy. The image acquisition device 8 or the host system can obtain the shape data of the core fuse and the coordinate data of the core fuse according to the collected image data, so as to provide accurate data support for the welding position and welding trajectory of the welding mechanism 7. Because the core fuse is thin and is prone to a small amount of displacement or position offset during transportation and flipping, the shape data of the core fuse and the coordinate data of the core fuse provided by the image acquisition device 8 in this embodiment provide data guidance for the welding position and trajectory of the welding mechanism 7, which is more conducive to improving the welding accuracy and improving the product reliability.

[0049] Preferably, the automatic flipping mechanism 3 also includes a lifting mechanism, the fixed end of the lifting mechanism is fixedly connected to the equipment bracket body 1, the movable end of the lifting mechanism is connected to the bearing plane of the automatic flipping mechanism 3, the bearing plane is arranged at the end of the automatic transmission track 2, and the movable end of the lifting mechanism controls the horizontal height of the bearing plane.

[0050] The automatic flipping mechanism 3 of the technical solution of this embodiment also includes a lifting mechanism. After the capacitor core is flipped to a predetermined posture, the horizontal height is adjusted by the lifting mechanism so that the core fuse can be in good contact with the connecting piece, thereby being able to adapt to capacitor cores and connecting pieces of different types and specifications. This allows the production line to quickly adjust production parameters according to market demand, improving production flexibility and market response speed.

[0051] Preferably, the welding equipment also includes a welding host 9 arranged in the equipment bracket body 1, and the welding host 9 is electrically connected to the welding mechanism 7. When the capacitor core is flipped over and the connecting piece is fixed, the welding host 9 drives the welding mechanism 7 to weld the core fuse and the connecting piece through the upper electrode.

[0052] In the technical solution of this embodiment, the welding host 9 is arranged at the lower position inside the equipment bracket body 1. On the one hand, it saves space, and on the other hand, it makes the welding host 9 closer to the welding mechanism 7 (welding head), so that the supply side and the energy release side can be closer, which is beneficial to improving the reliability of the equipment.

[0053] Preferably, the welding equipment further comprises a water chiller 10 arranged on the equipment support body 1, a circulating heat dissipation channel is arranged inside the welding host 9, and the water chiller 10 is connected to the circulating heat dissipation channel.

[0055] Preferably, the welding equipment further comprises a protective grating 11, and the protective grating 11 is arranged on both sides of the equipment support body 1. During the welding process, when the protective grating 11 collects a signal that an object enters the welding area, the welding mechanism 7 stops the welding action.

[0056] The technical solution of this embodiment sets up a protective grating 11. When an object or a person's limb enters the grating area during equipment operation, the welding action is immediately stopped or the equipment is shut down, which improves safety on the one hand and prevents equipment damage on the other.

[0057] Preferably, the welding equipment further comprises a control panel, which is connected to the host system signal, and receives welding parameters and core movement parameters set by the user.

[0058] The technical solution of this embodiment provides a control screen for human-computer interaction, through which the operator can adjust equipment-related parameters, such as welding parameters, information movement parameters, lifting height of the lifting mechanism, etc., thereby improving the flexibility of the equipment.

[0059] Preferably, the welding mechanism 7 is fixedly connected to the driving module 6 through a cylinder. When the welding mechanism 7 reaches a predetermined position, the welding mechanism 7 is pressed down to the core fuse position by driving the cylinder, and the welding host 9 drives the upper electrode on the welding mechanism 7 to discharge with the lower electrode 4 for welding.

[0060] This embodiment provides a method of driving the welding mechanism 7 downward, and the welding mechanism 7 is driven by a cylinder to press down to the position of the core fuse and the connecting piece, and the mechanism is simple and reliable. Of course, any driving mechanism in the prior art can also be used, the purpose is to achieve the displacement of the welding mechanism 7 in the vertical direction.
