[0029] The detection component includes a color mark sensor 2, an adjustment unit 3 and a control module. The adjustment unit 3 includes an adjustment block 301 and a rotating rod 302. The adjustment block 301 is arranged on the top of the workbench. One end of the adjustment block 301 is provided with a rotating hole 3011 adapted to the rotating rod 302. The rotating hole 3011 passes through the two opposite side walls of the adjustment block 301. One end of the rotating rod 302 is rotatably arranged on the adjustment block 301 through the rotating hole 3011. The color mark sensor 2 is arranged at the other end of the rotating rod 302. The color mark sensor 2 is arranged obliquely above the welding needle 101. The color mark sensor 2 is communicatively connected to the control module. First of all, it should be explained that the color of the connecting piece of this scheme is not consistent with that of the battery, and the color of the connecting piece is green. By setting a colored The color mark sensor 2 detects the color on the battery and transmits the detection data to the control module. The control module determines whether there is green on the detected battery, and can determine whether the connecting piece is set on the battery. Therefore, the battery welding equipment of this solution has the ability to determine whether the connecting piece has been placed on the battery, which solves the problem that the existing battery welding equipment cannot identify whether the battery connecting piece has been placed on the battery and can only be identified by the naked eye of the assembly line workers. In the actual operation process, the assembly line workers may not put the connecting piece on the battery due to lack of concentration and directly contact the battery welding equipment with the battery. In particular, the lithium manganese battery will have the risk of explosion when welded without a connecting piece due to its own battery characteristics.

[0030] It is worth noting that the present solution is further provided with an adjustment unit 3, which includes an adjustment block 301 and a rotating rod 302. The adjustment block 301 is arranged on the top of the workbench, and one end of the adjustment block 301 is provided with a rotating hole 3011 adapted to the rotating rod 302. The rotating hole 3011 passes through the two opposite side walls of the adjustment block 301. The present solution is provided with a rotating rod 302, and one end of the rotating rod 302 is rotatably arranged on the adjustment block 301 through the rotating hole 3011, so that the color mark sensor 2 rotates along with the rotation of the rotating rod 302, thereby adjusting the detection angle of the color mark sensor 2.

[0031] Furthermore, after the color mark sensor 2 has adjusted its angle, it is necessary to fix the color mark sensor 2 at the current angle. Based on this, the adjustment unit 3 of the present invention further includes a fixing screw 303. A through slot 3012 is further provided at one end of the adjustment block 301. One end of the through slot 3012 is communicated with the rotating hole 3011, and the other end thereof is communicated with the end face close to the adjustment block 301. The adjustment block 301 further includes a through hole, which passes through the other two opposite side walls of the adjustment block 301, and the through hole is communicated with the through slot 3012. The present invention is provided with a fixing screw 303. When the fixing screw 303 is tightened in the through hole, the size of the through slot 3012 is forced to be reduced, and the inner diameter of the rotating hole 3011 connected to the through slot 3012 is also forced to be reduced, resulting in the inability of the rotating rod 302 to rotate in the rotating hole 3011. After the color mark sensor 2 has adjusted its angle, the color mark sensor 2 is fixed at the current angle by tightening the fixing screw 303.

[0032] Furthermore, the welding assembly 1 of the present invention further comprises a battery fixture 102, the battery fixture 102 is provided with a battery slot 1021 adapted to a plurality of batteries, the top of the battery fixture 102 is provided with a connecting slot 1022 adapted to the connecting piece, the connecting slot 1022 is connected to the battery slot 1021, and the purpose of providing the battery fixture 102 in the present invention is to prevent the position of the battery or the connecting piece from shaking during the welding process of the welding assembly 1 on a plurality of batteries and the connecting piece, thereby affecting the welding effect. A battery fixture 102 is provided. The battery fixture 102 sets multiple batteries in a battery slot 1021, fixes the position of the batteries, and then inserts a connecting piece into the connecting slot 1022. Since the connecting slot 1022 and the battery slot 1021 are interconnected, the connecting piece is ensured to be set on the top of the multiple batteries. Due to the existence of the connecting slot 1022, the connecting piece cannot shake. Such a setting avoids the shaking of the position of the battery or the connecting piece during the welding process of several batteries and the connecting piece, thereby affecting the welding effect.

[0033] Furthermore, the battery slot 1021 is connected to the bottom surface of the battery fixture 102, and the height of the battery slot 1021 is the same as the height of the battery. Such a setting can directly install the battery in the battery slot 1021 through the bottom of the battery fixture 102, thereby ensuring the efficiency of installing multiple batteries in the battery fixture 102. The height of the battery slot 1021 is the same as the height of the battery, thereby ensuring that when the battery fixture 102 is placed vertically on the workbench, the battery installed therein will not shake due to height issues.

[0034] Furthermore, the top thickness of the battery fixture 102 is the same as the thickness of the connecting piece. This arrangement ensures that the surface of the connecting piece is flush with the surface of the battery fixture 102, which is convenient for the subsequent color code sensor 2 to smoothly detect the color of the connecting piece. It should be noted that the color of the battery fixture 102 of this solution is not the same as that of the connecting piece.

[0035] Furthermore, the connection groove 1022 of the present solution is arranged along the axial direction of the battery groove 1021 and penetrates the interior of the battery fixture 102. Such an arrangement ensures that after the connection piece is welded to multiple batteries, the welded product can be smoothly taken out from the bottom of the battery fixture 102.

[0036] Furthermore, the welding assembly 1 of the present solution also includes a foot switch 103, which is turned on by the operator's foot. The foot switch 103 is in communication connection with the control module. The welding needle 101 of the present solution is powered on by the welding machine, so that the welding needle 101 can weld the battery and the connecting piece. For safety reasons, the welding machine of the present solution is in communication connection with the control module. When the control module detects that the connecting piece exists on the top of the battery and the operator presses the foot switch 103, the control module will control the welding machine to start and power on the welding needle 101; otherwise, the control module will not control the welding machine to start.

[0037] Furthermore, the welding assembly 1 also includes a lifting cylinder 104, which is vertically arranged on the workbench. The output end of the lifting cylinder 104 clamps the welding needle 101. The lifting cylinder 104 controls the welding needle 101 to contact and weld with the connecting piece and the battery by extending and retracting its output end, or releases the contact between the welding needle 101 and the connecting piece and the battery to stop welding.

[0038] Furthermore, the welding needle 101 includes a connecting shaft and two welding heads, the two welding heads are symmetrically arranged at both ends of the connecting shaft, the connecting shaft is connected to the lifting cylinder 104, the two welding heads have the same height, and the spacing between the two welding heads is the same as the spacing between the two batteries, the common surface of the two welding heads is the same as the common surface of the two batteries, and there are two batteries in this scheme, that is, two batteries and one connecting piece are welded. By providing two welding heads, the positions of the two welding heads correspond one by one to the two welding points. When the lifting cylinder 104 descends, the lifting cylinder 104 can simultaneously drive the two welding heads to move toward the welding point of the connecting piece, so that the welding needle 101 of this scheme can simultaneously weld the two welding points.

[0039] Furthermore, the welding assembly 1 also includes a limiting clamp 105, which is arranged on a workbench. The limiting clamp 105 is provided with a limiting groove which is engaged with the outer wall of the battery fixture 102, so that the battery fixture 102 of this scheme can be engaged and placed in the limiting groove after the battery and the connecting plate are installed. At this time, the battery fixture 102 is restricted by the limiting clamp 105 to be directly below the two welding needles 101, ensuring that the two welding heads of the welding needle 101 of this scheme correspond one-to-one with the two welding points of the connecting plate.

[0040] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
