[0019] Advantages of the present invention:

[0040] Embodiment

[0041] Referring to Figure 1 , a positioning mechanism for the production and manufacturing of butt welding of busbars, comprising a moving mechanism 10, a welding machine 12, a conveying rack 13, and a positioning mechanism 20;

[0042] The welding machine 12 is placed on the side of the conveying rack 13, and the welding machine 12 is used for butt welding of busbars. The moving mechanism 10 is above the welding machine 12 and the conveying rack 13. The moving mechanism 10 is a common X and Y axis conveying mechanism, and a first hydraulic component 11 is installed on the moving mechanism 10. The movable part of the first hydraulic component 11 is connected to the positioning mechanism 20;

[0043] Through the above, it can be achieved that the busbar is restricted by the positioning mechanism 20, and the positioning mechanism 20 and the busbar are transported to the butt welding station of the welding machine 12 by the Y-axis transmission mechanism of the moving mechanism 10. Transporting to the welding station can ensure the hygiene of the conveying rack 13, and the welding machine 12 welds the two sections of busbars.

[0044] Referring to Figure 2 , the positioning mechanism 20 includes a bearing platform 21, a second hydraulic component 210, and a positioning block 211. A pair of second hydraulic components 210 are reciprocally and telescopically arranged on the bearing platform 21. The pair of second hydraulic components 210 are mirror-image distributed. The movable part of the second hydraulic component 210 is provided with a positioning block 211. A U-shaped channel 212 is milled on one side of the positioning block 211 deviating from the second hydraulic component 210. A bearing module 22 is rotatably arranged in the U-shaped channel 212. Expansion modules 23 are arranged on two adjacent side portions of the positioning block 211 close to the second hydraulic component 210;

[0045] Referring to Figure 3 and 5 5 , the carrier module 22 includes a first motor 220 and a second motor 223. Both the first motor 220 and the second motor 223 are installed along the inner edge of the U-shaped channel 212. The second motor 223 is located below the first motor 220. A first cylindrical sleeve 221 is installed on the moving part of the first motor 220, and a curved surface pad 222 is arranged on the surface of the first cylindrical sleeve 221. A second cylindrical sleeve 224 is installed on the moving part of the second motor 223, and a first carrier 225 is arranged on the surface of the second cylindrical sleeve 224. A linkage unit 226 is installed at a position where the positioning stop 211 is close to the U-shaped channel 212. The first carrier 225 is bent, and its bending angle is 90°. When a section of the first carrier 225 close to the second cylindrical sleeve 224 is at the same angle as the positioning stop 211, the other end of the first carrier 225 is outside the positioning stop 211;

[0046] Referring to Figure 4 and 9 9 , the linkage unit 226 includes a telescopic cavity 227, a linkage column 228, a linkage platform 229, a second elastic member 2210 and an opener 2211. The telescopic cavity 227 is reserved inside the positioning stop 211 close to the U-shaped channel 212. A linkage column 228 moves telescopically in the telescopic cavity 227. A linkage platform 229 is installed at the part of the linkage column 228 extending into the telescopic cavity 227. A second elastic member 2210 is arranged between the linkage platform 229 and the inner edge of the telescopic cavity 227. The second elastic member 2210 surrounds the surface of the linkage column 228. An opener 2211 is installed on the inner edge of the telescopic cavity 227, and an arc-shaped protrusion is arranged on the edge of the linkage platform 229 and touches the opener 2211.

[0047] Through the above content, the following can be achieved: relying on a pair of second hydraulic members 210 to move relative to each other, and the positioning stop 211 moves along the radial direction of the second hydraulic member 210, so that it can be applied to busbars of different specifications and can ensure the stable effect during the butt welding of the busbars;

[0048] When a pair of positioning stops 211 correspond to the position of the bus duct and move towards the bus duct as a whole, the positioning stops 211 are in contact with the side conveyor frame 13 of the bus duct. The linkage column 228 will be actuated to move towards the telescopic cavity 227, and the linkage platform 229 will come into contact with the opening and closing device 2211. The opening and closing device 2211 is divided into upper, middle, and lower sections. When the linkage column 228 moves telescopically, the linkage platform 229 comes into contact with the upper section of the opening and closing device 2211. At this moment, the second motor 223 operates, and under the linkage of the second cylindrical sleeve 224, the first carrier 225 rotates together, and the movement direction is towards the back of the positioning stop 211. After the pair of positioning stops 211 limit the side position of the bus duct, the hydraulic component two 210 is used to perform the lifting movement operation on the positioning stops 211. During the rising process of the positioning stops 211, the linkage column 228 is no longer in contact with the conveyor frame 13. Under the action of the second elastic component 2210, the linkage platform 229 and the linkage column 228 will be linked to reset. At this time, the linkage platform 229 comes into contact with the lower section of the opening and closing device 2211. When the second motor 223 rotates back to reset at this time, the inner edge of the first carrier 225 will be linked to move towards the direction of the bus duct. The first carrier 225 carries the bus duct to ensure the stable effect during the butt welding of the bus duct;

[0049] When the inner edge of the positioning stop 211 comes into contact with the side of the bus duct, the first motor 220 can be driven and the curved surface pad 222 can be linked to rotate by relying on the first cylindrical sleeve 221. The curved surface pad 222 moves from bottom to top. The curved surface pad 222 is made of a rough flexible material. When the curved surface pad 222 faces the side of the bus duct, the resistance between the positioning stop 211 and the bus duct can be increased, further improving the stability of the bus duct during processing. With the flexible characteristic of the curved surface pad 222 itself, it can avoid scratching the surface of the bus duct.

[0050] Refer to Figure 2 and 6 As shown in, the expansion module 23 includes a second carrier 230, an extension frame 231, and a cross member 232. The second carrier 230 is connected to the side position of the positioning stop 211. The extension frame 231 is arranged on one side of the second carrier 230 deviating from the positioning stop 211. A plurality of extension frames 231 are arranged, and cross members 232 are arranged between the plurality of extension frames 231. A receiving cavity 233 is reserved on the extension frame 231, and a telescopic cylinder 234 is arranged in the receiving cavity 233. An elastic component three is wound around the telescopic cylinder 234. A square cylinder 235 is arranged on the telescopic cylinder 234, and the square cylinder 235 moves telescopically in the receiving cavity 233. A square column 236 is arranged in the square cylinder 235 by relying on the first elastic component;

[0051] Through the above content, it can be achieved that: when a pair of positioning blocks 211 correspond to the position of the bus duct, when the whole moves toward the bus duct, the positioning blocks 211 fit with the conveying frame 13 at the edge of the bus duct, and the surface of the conveying frame 13 acts on the square tube 235, and the square tube 235 acts on the telescopic tube 234 to move into the storage cavity 233, and when the positioning block 211 approaches the bus duct, the square column 236 touches the edge of the bus duct, and as the positioning block 211 gradually restricts the edge of the bus duct, the square column 236 shrinks to the square tube 235. In the embodiment, when the bus duct is longer, several extension frames 231 will be unfolded under the action of the cross member 232. This is because the specifications of a single positioning block 211 are limited, and the extension and unfolding can be applicable to bus ducts of different lengths. After the positioning mechanism 20 is linked upward, the square cylinder 235 will be separated from the surface of the bus duct under the long-term action of the telescopic cylinder 234. At this time, the square column 236 is reset and located at the lower corner of the bus duct, which provides a load-bearing effect for the bus duct and ensures that the longer bus duct can still maintain a stable effect during welding.

[0052] Reference Figure 2 , 7 8, a limiting module 24 is installed on the opposite surface of a pair of positioning blocks 211, and the limiting module 24 includes a long strip 240, a telescopic seat 241 and a friction protrusion 243. The long strip 240 is installed on the surface of the positioning block 211, and the long strip 240 is distributed in a pair on the positioning block 211, and the pair of long strips 240 are distributed in a mirror image with respect to the U-shaped channel 212. A channel 1 is milled in the long strip 240, and a plurality of telescopic seats 241 are telescopically installed in the channel 1. A friction protrusion 243 is installed on the opposite surface of the telescopic seat 241 on the pair of positioning blocks 211, and an elastic member 242 is installed between the telescopic seat 241 and the channel;

[0053] The above content can be used to achieve the following: when a pair of positioning stops 211 move toward the edge of the bus duct, the bus duct will push the friction protrusion 243 and act on the telescopic seat 241 to enter channel one. When the thickness spacing of the bus duct is small, the friction protrusion 243 in the upper position will limit the upper position of the bus duct, that is, the friction protrusion 243 that is not pushed by the edge of the bus duct can limit the upper position of the bus duct, thereby further improving the stabilizing effect of the bus duct welding, and the friction protrusion 243 pushed by the edge of the bus duct can increase the resistance between the bus duct and the bus duct.

[0054] It should be understood that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, without undue experimentation, the development effort will be a routine task of design, fabrication, and production.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
