DETAILED DESCRIPTION

[0023] The present application relates to a tooling return conveyor line, which is explained in detail below through specific implementation methods.

[0024] After the battery cells are soldered in series, the pressing tooling pressed on the battery cells and the solder strips needs to be reflowed for subsequent welding cycles. In order to avoid the pressing tooling transported by the tooling transport device from colliding with the tooling piled up on the reflow conveyor line, causing damage to the pressing tooling or the conveyor line, the present application provides a tooling reflow conveyor line, which includes a conveying part 10, a detection part 30 and a blocking part 40.

[0025] according to Figure 2 As shown, the tooling return conveyor line includes a conveying portion 10 for transferring the transported compacting tooling from the input end to the output end for return, which includes a fixed bracket 11, a conveyor belt 12 and a power device; in this embodiment, the power device is installed on the fixed bracket 11 and the main body is located at the input end of the conveying portion 10; two conveyor belts 12 are provided and are installed in parallel on the fixed bracket 11 and connected to the power device. In this embodiment, the main part of the power device includes a driver, a driving pulley 13 and a synchronous shaft 14, wherein the driver is installed at the input end of the conveying part 10, the driver includes a motor 15 and a reducer 16 installed on the output shaft of the motor 15, and a driving pulley 13 is installed on the output shaft of the reducer 16. The driving pulley is connected to the driving pulley 13 on the other side through the synchronous shaft 14. The power device also includes two groups of driven pulleys 17 arranged parallel to the driving pulley 13, located at the output end of the conveying part 10 and installed on the fixed bracket 11. The two groups of driving pulleys 13 and the driven pulleys 17 are transmitted through the conveyor belt 12. When the driver drives, it drives the conveyor belt 12 installed on the driving pulley 13 and the driven pulley 17 to rotate, thereby carrying and transporting the compacting tooling placed on the conveyor belt 12.

[0026] according to Figure 2 As shown, multiple sets of relative limiting structures are provided between the input end and the output end of the conveying part 10, and the multiple sets of limiting structures are vertically arranged on the outside of the two conveyor belts 12 and connected to the fixed bracket 11, wherein the limiting structure includes a fixed side plate 21 and a limiting bar 22, the fixed side plate 21 is perpendicular to the conveyor belt 12 and is arranged on the fixed bracket 11, and the limiting bar 22 is installed on the inner side of the fixed side plate 21, and the spacing between the limiting bars 22 on the multiple sets of limiting structures relatively provided at the input end and the output end is the same as the distance of the long side of the clamping tooling; through the multiple sets of limiting structures provided, the clamping tooling can be fully limited along the conveying direction on the return conveying line.

[0027] according to Figure 3 and Figure 4As shown, since the pressing tooling needs to cooperate with the welding process for cyclic reflow, after the battery cell string welding is completed, the tooling transporting device will directly transport the completed pressing tooling with welding to the input end of the reflow conveyor line because it cannot determine the blockage of the tooling on the reflow conveyor line. This will cause tooling blockage and damage to the tooling or the conveyor line. Therefore, a detection unit 30 is provided at the input end of the conveying unit 10 for position detection of the transported pressing tooling, wherein the detection unit 30 includes two groups of relatively arranged support plates 31 and a detection component 32, the two groups of support plates 31 are respectively mounted on both sides of the fixed bracket 11 at the input end of the conveying unit 10, and the two groups of detection components 32 are respectively mounted on the fixed bracket 11 in parallel with each other through the support plates 31. In this embodiment, the detection component 32 uses a light curtain; through the setting of the detection unit 30, the position information of the pressing tooling at the input end of the conveying unit 10 can be obtained to prevent the transported tooling from causing blockage and damage to the tooling or the conveyor line.

[0028] according to Figure 3 and Figure 5 As shown, when the production task is about to be completed, the pressing tooling does not need to be circulated and refluxed. It is only necessary to reserve the corresponding welding tooling on the conveyor line. In order to make the tooling end the circulatory reflux action, a blocking part 40 is further provided on the conveying part 10 on the side of the detection part 30 close to the output end, which can block the pressing tooling, wherein the blocking part 40 has two groups, both including a fixing part 41, a cylinder 42 and a guide rod 43. The guide rod 43 is fixedly connected to the output end of the cylinder 42. The two groups of cylinders 42 are relatively installed on both sides of the fixed bracket 11 through the fixing part 41; when the tooling needs to be blocked, the cylinder 42 will push the guide rod 43 down to block the vacancies on both sides of the tooling, preventing it from continuing to be transported to the output end for reflux. By setting the blocking part 40, the tooling can be collected back to the reflux conveyor line at the end of the production task, and no reflux circulation is performed, which is convenient for the equipment operator to organize and summarize the tooling or change the tooling version.
