Description

Technical Field

[0001] This utility model relates to the technical field of positioning welding devices, specifically a lightning protection varistor module installation welding device. Background Technology

[0002] In the manufacturing process of varistor sheets, the positioning and welding of the varistor sheets is a crucial step. The welding quality directly affects the function and reliability of the varistor sheets. Traditional devices lack a structure that automatically adjusts the positioning based on the thickness of the varistor sheet to maintain balance, which can easily affect the electrical connection performance between the varistor sheet and the substrate, preventing it from being in an ideal horizontal state. This also reduces the welding quality and increases the defect rate. Furthermore, in most existing devices, the springs and elastic steel balls are difficult to disassemble and replace. As a result, the springs and elastic steel balls become less accurate after repeated use and cannot be replaced, which directly reduces the positioning accuracy and quality of the entire device. Utility Model Content

[0003] This utility model provides a lightning protection varistor module installation and welding device to solve the problem that the existing lack of adjustment mechanism makes it unable to adapt to the function of varistor sheets with thickness positive and negative differences, and the lack of disassembly and replacement device causes the positioning accuracy to deviate, thus making it impossible to replace and reducing the positioning accuracy of the device.

[0004] This utility model provides the following technical solution: a lightning protection varistor module installation and welding device, including an upper pressure plate and a pressure frame disposed inside the upper pressure plate, and further including: a top block disposed inside one side of the pressure frame, wherein an adjustment mechanism is installed inside the top block, the adjustment mechanism including an adjustment hole, an adjustment spring, a top column and an elastic steel ball, and an installation groove disposed inside the top surface of the top block, wherein a disassembly mechanism is provided on both sides inside the installation groove, the disassembly mechanism including an installation hole, an installation plate and an installation bolt.

[0005] As a preferred embodiment of this utility model, the adjusting hole is installed inside the top block, an adjusting spring is installed at the top of the adjusting hole, a top column is fixedly connected to the bottom of the adjusting spring, and an elastic steel ball is fixedly connected to the bottom of the top column.

[0006] As a preferred embodiment of this utility model, the mounting holes are opened on both sides of the inside of the mounting groove, and the mounting holes are threaded with mounting bolts, with a mounting plate penetrating through the top of the mounting bolts.

[0007] As a preferred embodiment of this utility model, the mounting plate is installed inside the mounting groove, and the bottom surface of the mounting plate is fixedly connected to the top of the adjusting spring.

[0008] As a preferred embodiment of this utility model, a hinge is fixedly connected to one side of the bottom surface of the upper pressure plate, and a lower pressure plate is fixedly connected to the bottom end of the hinge.

[0009] As a preferred technical solution of this utility model, the lower pressure plate is provided with a card frame inside, and pads are fixedly connected to the inside perimeter of the card frame. A balancing steel ball is slidably connected to the top of the pad.

[0010] As a preferred embodiment of this utility model, a telescopic spring is fixedly connected to the bottom end of the balancing steel ball, a disassembly plate is fixedly connected to the bottom of the telescopic spring, and fixing bolts penetrate both sides of the disassembly plate.

[0011] As a preferred technical solution of this utility model, a pad frame is fixedly connected to the outer ring of the bottom surface of the upper pressure plate, and buckles are fixedly connected to both ends of one side of the upper pressure plate.

[0012] Compared with the prior art, this utility model provides a lightning protection varistor module mounting and welding device, which has the following advantages:

[0013] The surge protector varistor module is installed with a welding device. Through the adjustment mechanism, a top block is installed on one side of the pressure frame when the device is to be used. An adjustment hole is set inside the top block, and an adjustment spring is installed inside the adjustment hole. A top post and an elastic steel ball are installed at the bottom of the adjustment spring. When the varistor sheet is thick, the elastic steel ball will push the top adjustment spring inward; when the varistor sheet is thin, the adjustment spring will push the bottom elastic steel ball downward. This allows it to adapt to varistor sheets with different thicknesses, preventing them from being out of ideal horizontal condition due to thickness differences, which would reduce welding quality and increase the defect rate.

[0014] The lightning protection varistor module installation and welding device, through the setting of the disassembly mechanism, has an installation groove set inside the top of the top block when the device is to be used. The installation groove is at the top of the adjustment hole, and the two are interconnected. The installation plate is installed inside the installation groove, and the installation bolts are installed on both sides of the installation plate. Since the installation plate is connected to the top of the adjustment spring, when the accuracy of the adjustment spring and the elastic steel ball is insufficient, the installation plate can be removed and a new adjustment spring and elastic steel ball can be installed. This achieves the function of disassembly and replacement, avoiding the situation where the lack of a replacement device leads to deviations that cannot be replaced, which would directly reduce the positioning accuracy and positioning quality of the entire device.

[0022] Specifically, the adjustment hole 401 is installed inside the top block 3, the top of the adjustment hole 401 is equipped with an adjustment spring 402, the bottom of the adjustment spring 402 is fixedly connected to a top post 403, and the bottom of the top post 403 is fixedly connected to an elastic steel ball 404.

[0023] In this embodiment, a top block 3 is installed on one side of the inside of the pressure frame 2. An adjustment hole 401 is provided inside the top block 3. An adjustment spring 402 is installed inside the adjustment hole 401. A top post 403 and an elastic steel ball 404 are installed at the bottom of the adjustment spring 402. When the varistor sheet is thick, the elastic steel ball 404 will push the top adjustment spring 402 inward. When the varistor sheet is thin, the adjustment spring 402 will push the bottom elastic steel ball 404 downward.

[0024] Specifically, mounting holes 601 are formed on both sides of the inside of the mounting groove 5. Mounting bolts 603 are threaded inside the mounting holes 601, and mounting plates 602 penetrate the top of the mounting bolts 603.

[0025] In this embodiment, an installation groove 5 is provided inside the top of the top block 3. The installation groove 5 is at the top of the adjustment hole 401 and the two are interconnected. An installation plate 602 is installed inside the installation groove 5. Installation bolts 603 are installed on both sides of the installation plate 602. Since the installation plate 602 is connected to the top of the adjustment spring 402, when the adjustment spring 402 and the elastic steel ball 404 are not accurate enough, the installation plate 602 can be removed and a new adjustment spring 402 and elastic steel ball 404 can be replaced.

[0026] Specifically, the mounting plate 602 is installed inside the mounting groove 5, and the bottom surface of the mounting plate 602 is fixedly connected to the top of the adjusting spring 402.

[0027] Specifically, a hinge 7 is fixedly connected to one side of the bottom surface of the upper pressure plate 1, and a lower pressure plate 8 is fixedly connected to the bottom end of the hinge 7.

[0028] In this embodiment, two hinges 7 are installed on one side edge of the upper pressure plate 1. The hinges 7 connect the upper pressure plate 1 and the lower pressure plate 8 together, so that the two pressure plates can be joined together for easy clamping.

[0029] Specifically, the lower pressure plate 8 has a retaining frame 9 inside, and pads 10 are fixedly connected around the inside of the retaining frame 9. A balancing steel ball 11 is slidably connected to the top of the pad 10.

An adjustment hole 401 is set inside the top block 3. An adjustment spring 402 is installed inside the adjustment hole 401. A top column 403 and an elastic steel ball 404 are installed at the bottom of the adjustment spring 402. When the varistor sheet is thick, the elastic steel ball 404 will push the top adjustment spring 402 inward. When the varistor sheet is thin, the adjustment spring 402 will push the bottom elastic steel ball 404 downward.

[0034] When the device is to be used, an installation groove 5 is provided inside the top of the top block 3. The installation groove 5 is at the top of the adjustment hole 401 and the two are interconnected. An installation plate 602 is installed inside the installation groove 5. Installation bolts 603 are installed on both sides of the installation plate 602. Since the installation plate 602 is connected to the top of the adjustment spring 402, when the adjustment spring 402 and the elastic steel ball 404 are not accurate enough, the installation plate 602 can be removed and a new adjustment spring 402 and elastic steel ball 404 can be replaced.

[0035] In summary, the welding device for installing the surge protection varistor module, through the setting of the adjustment mechanism 4, can adapt to varistor sheets with different differences, avoiding the situation where the varistor sheets cannot be in an ideal horizontal state due to differences in value, which would also reduce welding quality and increase the defect rate. Through the setting of the disassembly mechanism 6, it can be disassembled and replaced, avoiding the situation where the lack of a replacement device would lead to deviations that cannot be replaced, which would directly reduce the positioning accuracy and positioning quality of the entire device.
