Currently, the capacitor industry uses a soldering iron to solder the fuse and connecting piece, and the solder is tin-lead solder. It is a manual soldering process. During the soldering process, a tool is needed to hold the fuse in place, and then the soldering iron tip and tin-lead solder are used to solder the held fuse. The operator needs to bend over the whole time, which is slow, requires high skill level, is labor-intensive, and has high cost. Summary of the Invention
[0003] To address the aforementioned problems, the present invention aims to provide an automatic welding device and control method for the fuse and connecting piece of a power capacitor core. The automatic welding device for the fuse and connecting piece of a power capacitor core identifies the number and position of the fuses through an image acquisition device, and then completes the resistance welding of the fuses and connecting pieces through an automatic welding device, thereby reducing the labor intensity of personnel and lowering the welding cost.
[0004] To achieve the above objectives, the technical solution of the present invention is: an automatic welding device for the core fuse and connecting piece of a power capacitor, comprising:
[0005] Equipment support body;
[0006] An automatic transfer track is fixedly installed on the main body of the equipment bracket and is used to place and transfer capacitor cores;
[0007] An automatic flipping mechanism is rotatably connected to the main body of the equipment support. When the capacitor core reaches a predetermined position, the capacitor core is flipped.
[0008] The lower electrode is fixedly mounted on the main body of the equipment bracket, and the connecting piece is placed on the lower electrode;
[0009] The clamping mechanism is fixedly mounted on the main body of the equipment bracket at one end. When the connecting piece is placed on the lower electrode, the clamping mechanism switches to the locked state to fix the connecting piece.
[0010] The drive module is slidably fixed to the main body of the equipment bracket;
[0011] The welding mechanism is fixedly connected to the drive module at one end. The welding mechanism is provided with an upper electrode. After the capacitor core is flipped and the connecting piece is fixed, the welding mechanism welds the core fuse to the connecting piece through the upper electrode.
[0012] Preferably, the welding equipment further includes an image acquisition device, which is fixedly mounted on the drive module and is connected to the host system via a signal. When the device reaches a predetermined position, it sends the acquired image data to the host system.
[0013] Preferably, the image acquisition device sends the acquired image data to the host system. The image data includes at least core fuse shape data and core fuse coordinate data. The host system controls the welding mechanism to start welding a preset distance from the end of the core fuse.
[0014] Preferably, the automatic flipping mechanism further includes a lifting mechanism, the fixed end of which is fixedly connected to the main body of the equipment support, and the movable end of which is connected to the bearing plane of the automatic flipping mechanism.

[0017] Preferably, the welding equipment further includes a protective light grid, which is disposed on both sides of the main body of the equipment support.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0034] Referring to Figures 1 and 2, the core of this invention is to provide an automatic welding device for the fuse and connecting piece of a power capacitor core, comprising:
[0035] Equipment support body 1;
[0036] Automatic transfer track 2 is fixedly installed on the main body of the equipment support 1 and is used to place and transfer capacitor cores;
[0037] The automatic flipping mechanism 3 is rotatably connected to the main body 1 of the equipment support. When the capacitor core reaches the predetermined position, it flips the capacitor core.
[0038] The lower electrode 4 is fixedly mounted on the main body 1 of the equipment bracket, and the connecting piece is placed on the lower electrode 4;
[0039] The clamping mechanism 5 is fixedly mounted on the main body 1 of the equipment support at one end. When the connecting piece is placed on the lower electrode 4, the clamping mechanism 5 switches to the locked state to fix the connecting piece.
[0040] The drive module 6 is slidably fixed on the main body 1 of the equipment bracket;
[0041] The welding mechanism 7 is fixedly connected to the drive module 6 at one end. The welding mechanism 7 is provided with an upper electrode. After the capacitor core is flipped and the connecting piece is fixed, the welding mechanism 7 welds the core fuse to the connecting piece through the upper electrode.
[0042] The technical solution in this embodiment achieves continuous and efficient conveying and positioning of capacitor cores through an automated transport track and flipping mechanism. Compared with traditional manual operation, this automated process significantly improves the operating speed and overall efficiency of the production line. The use of a high-precision welding mechanism 7 and upper electrode ensures the welding quality between the core fuse and the connecting piece. The automated welding process reduces errors caused by human factors, resulting in more uniform and robust weld points, thereby improving the product qualification rate.
[0043] Preferably, the welding equipment further includes an image acquisition device 8, which is fixedly mounted on the drive module 6 and is connected to the host system via a signal. When it reaches a predetermined position, the image acquisition device 8 sends the acquired image data to the host system.
[0044] The technical solution of this embodiment uses the image acquisition device 8 to acquire image data of the connecting piece and the core fuse, thereby realizing production visualization and improving production efficiency.
[0045] Preferably, the image acquisition device 8 sends the acquired image data to the host system. The image data includes at least core fuse shape data and core fuse coordinate data. The host system controls the welding mechanism 7 to start welding a preset distance from the end of the core fuse.
[0046] In this embodiment, the power capacitor core is transferred to a predetermined position by an automatic transfer track 2 and an automatic flipping mechanism 3. The connecting piece placed on the lower electrode 4 is pressed and fixed by a pressing mechanism 5. Then, image data is acquired by an image acquisition device 8. Referring to Figure 3, the data of the core fuse in the image data acquired by the image acquisition device is shown. The host system can obtain the shape and coordinate data of each core fuse based on the image data. The welding mechanism 7 is driven to weld a preset length from the end of the core fuse along the extension direction of the fuse, thereby realizing the automatic welding of the power capacitor core fuse and the connecting piece, which greatly saves labor costs and greatly improves welding accuracy. The image acquisition device 8 or the host system can obtain the core wire shape data and core wire coordinate data based on the acquired image data, thereby providing accurate data support for the welding position and welding trajectory of the welding mechanism 7. Because the core wire is thin and is prone to small displacement or positional shift during transfer and flipping, the core wire shape data and core wire coordinate data 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 welding accuracy and product reliability.
[0047] Preferably, the automatic flipping mechanism 3 further includes a lifting mechanism. The fixed end of the lifting mechanism is fixedly connected to the main body 1 of the equipment support, and the movable end of the lifting mechanism is connected to the bearing plane of the automatic flipping mechanism 3. The bearing plane is located 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.
[0048] The automatic flipping mechanism 3 in this embodiment also includes a lifting mechanism. After flipping the capacitor core to a predetermined posture, the lifting mechanism adjusts the horizontal height, ensuring good contact between the core fuse and the connecting piece. This allows it to accommodate different types and specifications of capacitor cores and connecting pieces. This enables the production line to quickly adjust production parameters according to market demand, improving production flexibility and market responsiveness.
[0049] Preferably, the welding equipment further includes a welding host 9 disposed in the main body 1 of the equipment support. The welding host 9 is electrically connected to the welding mechanism 7. After the capacitor core is flipped and the connecting piece is fixed, the welding host 9 drives the welding mechanism 7 to weld the core fuse to the connecting piece through the upper electrode.
[0050] In this embodiment, the welding host 9 is located in the lower part of the equipment support body 1. This saves space and also makes the welding host 9 closer to the welding mechanism 7 (welding head), so that the supply side and the energy release side are closer, which is beneficial to improving the reliability of the equipment.
[0051] Preferably, the welding equipment further includes a chiller 10 mounted on the equipment support body 1, and the welding host 9 has a circulating heat dissipation channel inside, with the chiller 10 connected to the circulating heat dissipation channel.
[0052] The technical solution of this embodiment sets up a dedicated chiller 10, which is connected to the internal circulating heat dissipation channel of the welding host 9, thereby providing a cold source for the welding equipment and ensuring the safe and stable operation of the welding equipment.
[0053] Preferably, the welding equipment further includes a protective light grid 11, which is disposed on both sides of the equipment support body 1. During the welding process, if the protective light grid 11 collects a signal that an object has entered the welding area, the welding mechanism 7 will stop the welding action.
[0054] The technical solution of this embodiment is equipped with a protective light grid 11. When an object or a person's limb enters the light grid area, the welding action is immediately stopped or the equipment is shut down, which improves safety and prevents equipment damage.
[0055] Preferably, the welding equipment further includes a control panel, which is signal-connected to the host system and receives welding parameters and core movement parameters set by the user.
[0056] The technical solution of this embodiment provides a control screen for human-computer interaction. Through the control screen, operators can adjust relevant parameters of the equipment, such as welding parameters, information movement parameters, and lifting height of the lifting mechanism, thereby improving the flexibility of the equipment.
[0057] Preferably, the welding mechanism 7 is fixedly connected to the drive module 6 via a cylinder. When the welding mechanism 7 reaches the predetermined position, the cylinder is driven to press the welding mechanism 7 down to the core fuse position, and the welding host 9 drives the upper electrode on the welding mechanism 7 to discharge and weld with the lower electrode 4.
[0058] This embodiment provides a method for driving the welding mechanism 7 downward. The welding mechanism 7 is driven by a cylinder to press down to the position of the core fuse and the connecting piece. The mechanism is simple and reliable. Of course, any existing driving mechanism can also be used, the purpose being to achieve vertical displacement of the welding mechanism 7.
[0059] Based on the same concept, the present invention also provides a control method for an automatic welding equipment for fuses and connecting pieces of a power capacitor core, comprising the following steps:
[0060] The power capacitor core is transferred to a predetermined position via the automatic transfer track 2 and the automatic flipping mechanism 3;
[0061] The connecting piece is placed on the lower electrode 4 and fixed by the clamping mechanism 5;
[0062] The image acquisition device 8 acquires the core fuse shape data and core fuse coordinate data of the power capacitor core;
[0063] Based on the core fuse shape data and core fuse coordinate data, the welding mechanism 7 is driven to start welding a preset distance from the end of the core fuse.
[0064] In this embodiment, the power capacitor core is transferred to a predetermined position by an automatic transfer track 2 and an automatic flipping mechanism 3. The connecting piece placed on the lower electrode 4 is pressed and fixed by a clamping mechanism 5. Then, image data is acquired by an image acquisition device 8. The host system can obtain the shape and coordinate data of each core fuse based on the image data. The welding mechanism 7 is driven to weld a preset length from the end of the core fuse along the extension direction of the fuse, thereby realizing the automatic welding of the power capacitor core fuse and the connecting piece, which greatly saves labor costs and greatly improves welding accuracy.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
