Description

Technical Field

[0001] The invention relates to a device related to an automatic tape winding robot for a battery pack copper busbar connector, in particular to an adhesive and cutting device for an automatic tape winding robot for a battery pack copper busbar connector. Background Art

[0002] The copper busbar connector is an important component in new energy battery packs. It plays the role of transmitting current and connecting electrical equipment in the circuit. Generally, the surface of the copper busbar connector is usually wrapped with fire-proof insulating tape, and the end is exposed to achieve electrical connection. That is, the copper busbar connector plays a role in high-voltage connection between battery modules and battery modules, and between battery modules and BDU (battery pack disconnect unit).

[0003] The automatic tape winding equipment for the battery pack copper bus connector is a special equipment. The automatic tape winding robot on the equipment automatically winds the tape on the battery pack copper bus connector (workpiece) in the length direction. Common automatic tape winding robots will have a sticking and cutting device to complete the sticking of the tape on the battery pack copper bus connector at the initial stage of the automatic tape winding process, and cut the tape at the end stage.

[0004] However, the structure of the existing adhesive tape automatic winding robot is as follows: Figure 1 As shown in the figure, the surface on the main body in the direction of the cutting edge forms a snap-in portion for positioning the tape and a groove portion for inserting the workpiece, and the groove width corresponds to the width of the workpiece. The overlapping tape and the workpiece are passively inserted into the groove portion along the extension direction of the thickness of the workpiece. In this process, the adhesive surface of the tape in the groove portion and the single-side surface where the length and width of the workpiece are located are face-to-face bonded and pressed, and then the tape and the workpiece are synchronously detached from the groove portion to complete the adhesion of the tape on the battery pack copper busbar connector.

[0005] In the bonding and cutting device of the above structure, during the bonding process of the tape on the copper busbar connector of the battery pack, the tape can only be bonded to the single-side surface where the length and width of the workpiece are located. Considering that the width-to-thickness ratio of the copper busbar connector workpiece is relatively large, the width is significantly greater than the thickness. Therefore, the bonding effect that can be achieved by the bonding method similar to the above-mentioned single-side surface in the width direction of the workpiece and the tape will be relatively poor. If the viscosity of the tape itself is low, the tape is likely to detach from the surface of the workpiece or even fall off.

[0006] Therefore, the present invention is proposed. Summary of the invention

[0007] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art and to provide a bonding and cutting device for an automatic tape winding robot for a battery pack copper busbar connector, which is applied to the automatic tape winding equipment for the battery pack copper busbar connector. When the automatic tape winding robot on the equipment automatically winds the tape on the battery pack copper busbar connector in sequence in the length direction, the adhesive surface of the tape and a pair of surfaces where the length and width of the battery pack copper busbar connector are located can be bonded to each other in the bonding stage.
