Description

Technical Field

[0001] The present invention relates to the technical field of capacitors, in particular to a welding pin device for capacitor production equipment. Background Art

[0002] A capacitor is a device that holds an electric charge. It is one of the most widely used electronic components in electronic devices and is widely used in circuits for DC isolation, AC transmission, coupling, bypassing, filtering, tuning circuits, energy conversion, and control.

[0003] The production of existing film capacitors mainly includes the following steps: (1) making a core. The core can be made by overlapping metal foil (metal foil serves as an electrode) and plastic film and then winding them together. Alternatively, a very thin layer of metal can be deposited on the plastic film (the deposited metal layer serves as an electrode) to obtain a metallized film, and then the metallized film is wound to make a core. The core made by winding is usually cylindrical (usually, the cylindrical core is flattened by hot pressing to make a flat cylindrical core). (2) energizing the core. Energizing is to apply voltage to the two conductive ends of the core to eliminate the internal conductive hidden dangers of the core and allow the internal conductive defects of the core to self-heal. (3) Welding pins. Welding is to weld conductive pins to the two conductive ends of the core. (4) Encapsulation. Encapsulation is to impregnate the outside of the core with soldered pins with epoxy resin, or to place the core with soldered pins into a plastic shell and fill the plastic shell with epoxy resin to fix the core. After the core has undergone the energizing, soldering pins, and encapsulation processes, it becomes a finished capacitor.

[0004] In order to improve the efficiency of welding the pins of the core, a special welding device is required to automatically weld the conductive pins at the two conductive ends of the core. Summary of the Invention

[0005] The present invention overcomes the shortcomings of the prior art and provides a pin welding device for capacitor production equipment, which can automatically weld conductive pins at two conductive ends of a core, thereby improving welding efficiency.

[0006] To achieve the above-mentioned object, the present invention adopts a technical solution as follows: a pin welding device for capacitor production equipment, comprising a frame, a welding area for welding the pins to the core, and a welding mechanism, a core loading mechanism, and a pin belt conveying mechanism respectively provided near the welding area of ​​the frame.

[0007] The welding mechanism includes a first electric heating block and a second electric heating block arranged opposite to each other, the first electric heating block and the second electric heating block are arranged on a frame for movement along the X-axis direction, the first electric heating block and the second electric heating block can move toward or away from each other, the first electric heating block and the second electric heating block can be simultaneously moved in the vertical direction on the frame, and the first electric heating block and the second electric heating block can simultaneously move into or out of the welding area;

[0008] The core loading mechanism includes a loading seat, an upper clamp and a lower clamp. The loading seat can be slidably arranged on the frame along the Y-axis direction. The upper clamp or the lower clamp can be slidably arranged on the loading seat along the vertical direction. The corresponding lower clamp or the upper clamp is fixedly arranged on the loading seat. When the upper clamp and the lower clamp clamp the core, the loading seat can move the core to the welding area.

[0009] The pin belt conveying mechanism includes a conveying track for conveying the pin belt, which is arranged along the X-axis direction. When the pin belt is conveyed along the conveying track, the pin belt can move the pins thereon to the welding area one by one.

[0010] By adopting the above scheme, the structures of the first electric heating block and the second electric heating block are similar, and they generate heat when energized. The conveying track is used to transmit the pin belt, which is composed of a number of pins pasted on the paper belt at intervals. In this way, the pin belt transfers the pins on it to the welding area, and the upper core mechanism transfers the core to the pin. The core can be hot-pressed and welded with the corresponding pins on the pin belt through the welding mechanism. After hot-pressing welding, the core can follow the pin belt to enter the subsequent processing steps, and the next pin can be hot-pressed and welded with the next core. It can work continuously and uninterruptedly, thereby improving the welding efficiency. In addition, the first electric heating block and the second electric heating block can not only move toward or away from each other, but also move into or out of the welding area in the vertical direction. When welding is required, the first electric heating block and The second electric heating block can be moved into the welding area at the same time, and move toward each other to heat-press the two sides of the core respectively, so that the pins are welded at the two conductive ends of the core respectively; when welding is completed, the first electric heating block and the second electric heating block move back to back and move out of the welding area at the same time to avoid interfering with the transmission of the pin belt. When welding the next core, the first electric heating block and the second electric heating block are moved into the welding area again, and the upper clamp and the lower clamp can move along the Y-axis direction following the loading seat to transfer the clamped core to the welding area. When the first electric heating block and the second electric heating block are hot-pressed, the upper clamp and the lower clamp release the core, and are driven by the loading seat to clamp the next core, and then the next core is sent to the welding area. It can automatically weld the conductive pins at the two conductive ends of the core, thereby improving the welding efficiency.

[0011] A further arrangement of the present invention is that: the upper clamp is fixed with a first upper clamp and a second upper clamp at intervals or integrally provided in the Y-axis direction, the first upper clamp is located on the side of the second upper clamp away from the welding area, the lower clamp is fixed with a first lower clamp or integrally provided at the corresponding first upper clamp, the lower clamp is fixed with a second lower clamp or integrally provided at the corresponding second upper clamp, the frame is provided with a core-to-be-loaded area beside the welding area, the frame is provided with a clamping mechanism that can clamp or release the core at the core-to-be-loaded area, when the loading seat moves away from the welding area, the second upper clamp and the second lower clamp can move with the loading seat to the core-to-be-loaded area; when the loading seat moves toward the welding area, the second upper clamp and the second lower clamp can move with the loading seat to the welding area, and the first upper clamp and the first lower clamp can move with the loading seat to the core-to-be-loaded area.

[0012] The first clamp and the second clamp are respectively provided with a first upper clamp and a second lower clamp, and the first upper clamp and the second lower clamp are provided with a first lower clamp and a second lower clamp, and the first upper clamp is located on the side of the second upper clamp away from the welding area. During the core loading process, the clamping mechanism can clamp the core in the core loading area to prevent it from falling. When the first upper clamp and the first lower clamp clamp the new core, the second upper clamp and the second lower clamp can simultaneously clamp the core in the core loading area to be loaded. At this time, the clamping mechanism releases the clamping of the core in the core loading area, and the loading seat moves toward the welding area to transfer the core in the core loading area to the welding area, and at the same time, the new core is transferred to the core loading area to be loaded. At this time, the clamping mechanism clamps the core, and then the loading seat moves away from the welding area, and then the above action is performed. In this way, not only the external core can be transferred to the core loading area, but also the core in the core loading area can be transferred to the welding area, and this cycle is repeated, which can improve the efficiency of core loading.
