Description

Technical Field

[0001] This utility model relates to a welding fixture for battery busbars and tabs, specifically to a battery busbar template cooling device. Background Technology

[0002] In existing technologies, the welding of battery tabs to the busbar, such as Figure 4 As shown, the device includes a first base and a second base arranged in parallel, with the length direction of the first and second bases being the front-to-back direction. A lead screw assembly and a first guide rail are fixedly mounted on the upper end face of the first base, and a second guide rail is fixedly mounted on the upper end face of the second base. A bracket for mounting the busbar template is slidably mounted on the first and second guide rails, and the bracket is fixedly connected to the slider of the lead screw assembly. A limiting seat is fixedly mounted between the first and second bases. The bracket moves along the length direction of the first guide rail above the limiting seat. The side of the first base facing the second base has a first stepped surface, and the lower end face of the busbar template contacts the first stepped surface. Several spray pipes are fixedly mounted below the horizontal plane where the first stepped surface is located, and several spray holes are located on the upper end face of the spray pipes, with the spray pipes located between the first base and the limiting seat. A battery lifting platform is located above the first and second bases. The battery lifting platform is existing technology and will not be described in detail here. Directly below the battery lifting platform is the welding station for the battery tabs and busbars, located between the first base and the mounting base.

[0003] During operation, driven by the lead screw assembly, as the support moves the busbar template from the inlet to the workstation, the battery lifting platform descends. The battery tabs fixed on it are inserted into the busbar grooves on the busbar template, contacting the molten lead in the grooves. Simultaneously, the spray pipes begin spraying water to cool the busbar template, thus completing the welding of the busbar and the tabs. After welding, the template is reset. During this process, because the busbar template is removed from the lead pot, each surface is covered with molten lead. Before moving to the workstation, the molten lead on the upper surface is scraped off by a scraper, leaving only the molten lead in the busbar grooves. However, the surrounding area and bottom cannot be scraped off, resulting in molten lead dripping during movement. When the template reaches the workstation, before the battery lifting platform descends, the spray pipes have not yet sprayed water, and the dripping molten lead solidifies, clogging the spray nozzles. This wastes molten lead and affects the cooling effect of the busbar template. Excessive nozzle blockage can even lead to incomplete busbar welding, affecting battery quality. Summary of the Invention

[0004] This utility model proposes a battery busbar template cooling device that can collect the lead liquid dripping from the busbar template when it moves to the work position, preventing the lead liquid from dripping and clogging the through holes, thus ensuring the cooling effect and the quality of the battery.

[0005] The technical solution disclosed in this utility model is as follows: A battery busbar template cooling device includes a first base and a second base arranged in parallel, wherein the length direction of the first base and the second base is the front-to-back direction.

[0006] A lead screw assembly and a first guide rail are fixedly installed on the upper end face of the first base, and a second guide rail is fixedly installed on the upper end face of the second base.

[0007] The bracket for installing the busbar template is slidably mounted on the first guide rail and the second guide rail, and the bracket is fixedly connected to the slider of the lead screw assembly.

[0008] A limiting seat is fixedly installed between the first base and the second base, and the bracket moves along the length of the first guide rail above the limiting seat.

[0009] The side of the first base facing the second base has a first stepped surface, and the lower end face of the busbar template is in contact with the first stepped surface.

[0010] Several spray pipes are fixedly installed below the horizontal plane where the first step surface is located, and several spray holes are located on the upper end face of the spray pipes. The spray pipes are located between the first base and the limiting seat.

[0011] The opposing surfaces of the first base and the mounting base have a second stepped surface, and the horizontal plane containing the second stepped surface is located between the horizontal plane containing the first stepped surface and the horizontal plane containing the upper end face of the injection pipe.

[0012] The collecting tray includes a base plate with flanges around its four sides. The two sides of the base plate are located on the second stepped surfaces of the first base and the mounting base, respectively. The rear end of the base plate is fixedly connected to a drive unit for driving the base plate to move back and forth on the second stepped surface.

[0013] Based on the above scheme, as a preferred option, the bottom of the spray pipe is connected to a water source through a water inlet pipe, and the water inlet pipe has a valve.

[0014] Based on the above scheme, as a preferred option, the drive unit is a cylinder.

[0015] Based on the above scheme, as a preferred option, a connecting plate is fixedly installed at the front end of the busbar template, a vertical rod is fixedly installed at the front end of the connecting plate, a horizontal plate is fixedly connected to the upper end of the vertical rod, and the front end of the horizontal plate is fixed to the bracket.

[0016] Based on the above scheme, as a preferred option, one end of the injection pipe is fixed on the first base, and the other end is fixed on the limiting seat.

[0017] Based on the above scheme, as a preferred embodiment, a battery lifting platform is provided above the first base and the second base. Directly below the battery lifting platform is a welding station for battery tabs and busbars. The station is located between the first base and the mounting base. A first proximity switch is fixedly installed on the side of the limiting seat facing the first base in front of the station, and a second proximity switch is fixedly installed on the side of the limiting seat facing the first base. The first proximity switch and the second proximity switch are electrically connected to a cylinder.

[0018] Based on the above scheme, as a preferred option, the first proximity switch and the second proximity switch are located on the same horizontal plane.

[0019] Compared with the prior art, the present invention has the following advantages: by setting a second step surface between the first step surface and the upper end surface of the spray pipe for the collection plate to move on, the collection plate can move to or away from the work station under the drive of the cylinder during use. When the busbar template moves to the work station, the lead liquid dripping from the busbar template can be collected, avoiding the lead liquid dripping into the spray hole and clogging the through hole, ensuring the cooling effect and ensuring the quality of the battery.

[0020] The lead liquid dripping into the collection tray can be collected for recycling and reuse. Compared with traditional tooling where lead liquid drips onto the ground or onto the spray pipes from the gaps between the spray pipes, making collection inconvenient or even impossible, this method saves costs.

[0021] The limit seat serves to limit the movement and prevent the battery lifting platform from descending excessively and damaging the terminals.

[0022] The collection tray is made of stainless steel, which facilitates the melting and reuse of the collected molten lead later. Attached Figure Description

At the same time, the second proximity switch is triggered, transmitting signals to the cylinder and valve. The cylinder drives the base plate to leave the workstation for reset, the valve opens, and the spray pipe starts spraying water to cool the busbar template, thereby completing the welding of the busbar and the tabs. After welding, the platform is reset.
