Technical Field

[0001] This application relates to the field of fuse assembly equipment, and more particularly to a fuse wire resistance welding mechanism. Background Technology

[0002] After the fuse wire is threaded, the upper end of the wire is cut, and a section of the wire protrudes. To properly handle this protruding wire, the existing process requires bending it to fit the inner cap and welding it onto the inner cap to ensure the fuse's functionality.

[0003] This application studies a resistance welding mechanism for fuse wires, which can conveniently complete the wire bending and welding processes, thereby improving production efficiency. Utility Model Content

[0004] In order to facilitate the wire bending and welding processes and improve production efficiency, this application provides a resistance welding mechanism for fuse wire.

[0005] This application provides a resistance welding mechanism for fuse wires, which adopts the following technical solution:

[0006] A resistance welding mechanism for fuse wire includes an upper bending mechanism and an upper welding mechanism. The upper bending mechanism bends the wire to the inner cap end face of the ceramic tube. The upper welding mechanism includes an upper positive electrode welding assembly and an upper negative electrode welding assembly, both equipped with a spot welding power line. The upper positive electrode welding assembly includes a first driving member and an upper positive electrode welding component. The upper negative electrode welding assembly includes a second driving member and an upper negative electrode welding component. The first driving member drives the upper positive electrode welding component to abut against the inner cap end face, and the second driving member drives the upper negative electrode welding component to cover the outer periphery of the inner cap. A circuit is formed between the upper positive electrode welding component and the upper negative electrode welding component.

[0007] By adopting the above technical solution, the wire is bent to fit the inner cap of the ceramic tube by the upper bending mechanism, preparing for the subsequent welding of the wire and the inner cap. After the wire is bent, it is conveyed to the upper welding mechanism by the equipment grippers. The first driving component drives the upper positive welding component to press against the end face of the inner cap, and the second driving component drives the upper negative welding component to cover the outer periphery of the inner cap. The inverter resistor power supply host is connected through the spot welding power line. The host sets the parameters and triggers the welding, so that a circuit is formed between the upper positive welding component and the upper negative welding component, welding the wire and the inner cap together. This allows for convenient bending of the wire and completion of the welding process, improving production efficiency.

[0008] Optionally, the upper positive electrode welding component includes an upper positive electrode conductive block and an upper positive electrode extension post. The upper positive electrode extension post is connected to one side of the upper positive electrode conductive block, and the first driving member drives the upper positive electrode conductive block to move vertically.

The second driving component is a gripper cylinder. Both grippers of the gripper cylinder are connected to the upper negative electrode conductive block, and both upper negative electrode conductive blocks are connected to the upper negative electrode insert. The second driving component drives the two negative electrode conductive blocks to bring the two upper negative electrode inserts into contact and form a clamping groove.

[0011] Optionally, the upper welding mechanism further includes a return member and a third driving member, wherein the third driving member drives the return member to move in the vertical direction.

[0012] Optionally, the upper bending mechanism includes a fourth driving member, a bending lower block, a fifth driving member, a moving plate, a sixth driving member, a wire bending component, a seventh driving member, and a lower pressure rod. The fourth driving member drives the bending lower block to move vertically, the fifth driving member drives the moving plate to move vertically, the sixth driving member and the wire bending component are mounted on the moving plate, and drive the wire bending component to move horizontally. The wire bending component has a bending groove, and the seventh driving member drives the lower pressure rod to enter or leave the bending groove.

[0013] Optionally, it also includes a CCD vision inspection mechanism, which is disposed on one side of the upper welding mechanism. The CCD vision inspection mechanism includes a light source, a camera and an eighth driving component. The light source is located above the camera, and the eighth driving component drives the light source to move.

[0014] Optionally, it also includes a camera light source assembly, which is disposed on one side of the light source.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. The upper bending mechanism bends the wire to fit the inner cap of the ceramic tube, preparing for subsequent welding of the wire and the inner cap. After bending, the wire is conveyed to the upper welding mechanism by the equipment grippers. The first drive unit drives the upper positive welding part to press against the end face of the inner cap, and the second drive unit drives the upper negative welding part to cover the outer periphery of the inner cap. The inverter resistor power supply is connected to the main unit through the spot welding power line. The main unit sets parameters and triggers welding, so that a circuit is formed between the upper positive welding part and the upper negative welding part, welding the wire and the inner cap together. This allows for convenient bending of the wire and completion of the welding process, improving production efficiency.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses a resistance welding mechanism for fuse wires. (Refer to...) Figure 1 The fuse wire resistance welding mechanism includes an upper bending mechanism 1 and an upper welding mechanism 2. When the ceramic tube is conveyed to the upper bending mechanism 1 through the equipment gripper, the upper bending mechanism 1 bends the wire to the inner cap end face of the upper end of the ceramic tube, and then conveys it to the upper welding mechanism 2 through the equipment gripper to weld the wire and the inner cap.

[0030] Reference Figure 2 The upper welding mechanism 2 includes an upper positive electrode welding assembly 21 and an upper negative electrode welding assembly 22, both equipped with a spot welding power line. The upper positive electrode welding assembly 21 includes a first driving member 211 and an upper positive electrode welding member 212. The first driving member 211 is a telescopic cylinder. The upper negative electrode welding assembly 22 includes a second driving member 221 and an upper negative electrode welding member 222. The first driving member 211 drives the upper positive electrode welding member 212 to abut against the end face of the inner cap. The second driving member 221 drives the upper negative electrode welding member 222 to cover the outer periphery of the inner cap. A circuit is formed between the upper positive electrode welding member 212 and the upper negative electrode welding member 222. In this embodiment, the spot welding power line is connected to the inverter resistor power supply host. The host is used to set parameters and trigger welding, thereby forming a circuit between the upper positive electrode welding member 212 and the upper negative electrode welding member 222, welding the wire and the inner cap together.

[0031] In some embodiments, the upper positive electrode welding component 212 includes an upper positive electrode conductive block 2121 and an upper positive electrode extension post 2122. The upper positive electrode extension post 2122 is connected to one side of the upper positive electrode conductive block 2121, and the first driving member 211 drives the upper positive electrode conductive block 2121 to move vertically. In this embodiment, the welding power line is disposed on the upper positive electrode conductive block 2121, and the first driving member 211 drives the upper positive electrode conductive block 2121 to move the upper positive electrode extension post 2122 downward to abut against the upper end face of the inner cap of the ceramic tube.

[0032] In some embodiments, the upper positive electrode welding assembly 21 further includes an upper pressure regulator 213, which is connected between the output end of the first drive member 211 and the upper positive electrode conductive block 2121. The first drive member 211 drives the upper pressure regulator 213 to move downward, and the upper positive electrode extension post 2122 abuts against the upper end surface of the ceramic tube. By obtaining the downward pressure on the ceramic tube through the upper pressure regulator 213, the relevant pressure can be better adjusted.

[0033] Reference Figure 3In some embodiments, the upper negative electrode welding component 222 includes an upper negative electrode conductive block 2221 and an upper negative electrode insert 2222. The second driving component 221 is a gripper cylinder, with both grippers of the gripper cylinder connected to the upper negative electrode conductive block 2221. Each upper negative electrode conductive block 2221 is connected to the upper negative electrode insert 2222. The second driving component 221 drives the two negative electrode conductive blocks to bring the two upper negative electrode inserts 2222 into contact, forming a clamping groove. In this embodiment, the welding power line is connected to the upper negative electrode conductive block 2221. When the upper negative electrode inserts 2222 are in contact, the inner cap of the ceramic tube is in contact with the clamping groove, achieving the coverage of the outer periphery of the inner cap by the upper negative electrode insert 2222.

[0034] In some embodiments, the upper welding mechanism 2 further includes a return member 23 and a third driving member 24. The third driving member 24 drives the return member 23 to move vertically. The central axis of the return member 23 is on the same straight line as the central axis of the upper positive electrode extension column 2122. When the ceramic tube is rotated between the return member 23 and the upper positive electrode extension column 2122, the central axis of the ceramic tube is also on the same straight line as their central axes. The third driving member 24 is a telescopic cylinder. The third driving member 24 drives the return member 23 to move upward and press the ceramic tube upward to the position corresponding to the upper negative electrode welding assembly 22, so that the upper negative electrode insert 2222 can accurately cover the inner cap.

[0035] Reference Figure 4 In some embodiments, the upper bending mechanism 1 includes a fourth driving member 11, a bending lower top block 12, a fifth driving member 13, a moving plate 14, a sixth driving member 15, a wire bending member 16, a seventh driving member 17, and a lower pressure rod 18 (in conjunction with...). Figure 1 The fourth driving member 11 drives the bending lower top block 12 to move vertically, the fifth driving member 13 drives the moving plate 14 to move vertically, the sixth driving member 15 and the wire bending member 16 are mounted on the moving plate 14 and drive the wire bending member 16 to move horizontally. The wire bending member 16 has a bending groove 19. The seventh driving member 17 drives the lower pressure rod 18 to enter or leave the bending groove 19.

[0036] The fourth drive component 11, the fifth drive component 13, the sixth drive component 15, and the seventh drive component 17 are all telescopic cylinders. The fourth drive component 11 drives the bending lower top block 12 to press the lower end face of the ceramic tube upward. The fifth drive component 13 drives the moving plate 14 to move the sixth drive component 15 and the wire bending component 16 upward to the position corresponding to the wire on the upper end face of the ceramic tube. The sixth drive component 15 drives the wire bending component 16 to move forward, so that the wire enters the bending groove 19 and bends the wire to one side through the bending groove 19. The seventh drive component 17 drives the lower pressure rod 18 to enter the bending groove 19 and press the wire tightly against the inner cap to achieve the bending of the wire.

[0037] In some embodiments, the fuse wire resistance welding mechanism further includes a CCD vision inspection mechanism 3, which is located on one side of the upper welding mechanism 2. The CCD vision inspection mechanism 3 includes a light source 31, a camera 32, and an eighth driving component 33. The light source 31 is located above the camera 32, and the eighth driving component 33 is a telescopic cylinder that drives the light source 31 to move. The eighth driving component 33 drives the light source 31 to a suitable position, and the camera 32 and the light source 31 capture image information of the top and bottom surfaces of the ceramic tube, which is then transmitted to the CCD vision image processing system. Based on pixel distribution, brightness, color, and other information, the image system converts the image information into digital signals. The image system performs various calculations on the digital signals to extract features of the side, top, and bottom surfaces of the product, and the image is directly displayed on the screen. The right side of the screen is set with image parameter templates. Based on the appearance features and laser engraving features on the displayed image, the image processing system calculates and compares the parameters to automatically determine whether the ceramic tube welding is qualified.

[0038] In some embodiments, the CCD vision inspection mechanism 3 further includes a camera light source assembly 34, which is disposed on one side of the light source 31 to ensure that the light source 31 can emit light and illuminate the ceramic tube in the expected manner.

[0039] The implementation principle of a fuse wire resistance welding mechanism according to an embodiment of this application is as follows: the upper bending mechanism 1 bends the wire to fit the inner cap at the upper end of the ceramic tube, preparing for subsequent welding of the wire and the inner cap. After the wire is bent, it is conveyed to the upper welding mechanism 2 by the equipment grippers. The first driving member 211 drives the upper positive electrode welding member 212 to press against the end face of the inner cap, and the second driving member 221 drives the upper negative electrode welding member 222 to cover the outer periphery of the inner cap. The inverter resistor power supply host is connected through a spot welding power line. The host sets parameters and triggers welding, thereby forming a circuit between the upper positive electrode welding member 212 and the upper negative electrode welding member 222, welding the wire and the inner cap together. This allows for convenient bending of the wire and completion of the welding process, improving production efficiency.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
