Description

Technical Field

[0001] This utility model relates to the field of riveting equipment technology, specifically to a multilayer busbar riveting equipment. Background Technology

[0002] Laminated busbar riveting equipment is an automated or semi-automated device specifically designed for riveting processes during the manufacturing of laminated busbars. Laminated busbars are typically composed of multiple layers of conductive layers (such as copper or aluminum) and insulating layers that are alternately laminated. They are widely used in new energy, power electronics, electric vehicles, frequency converters and other fields for efficient transmission of large currents and reduction of electromagnetic interference.

[0003] As disclosed in the authorization announcement number CN205985652U, a double-sided press-fit riveted laminated busbar includes a conductive layer and an insulating layer. A riveting head is installed on the conductive layer of the laminated busbar. The riveting head includes an insert and an outer sleeve. The insert is embedded in the outer sleeve, clamping the conductive layer between the insert and the outer sleeve. A groove is formed on the insert, and a first screw hole is formed at the bottom of the groove. A second screw hole is formed on the outer sleeve.

[0004] Although it achieves the use of double-sided press-fit rivet joints, the rivet joint insert has a groove, so that the bottom plane of the groove is on the same plane as the end face of other conductive joints. This allows the use of the same screws during installation, ensuring that the overall height of the stacked busbars and modules is consistent and the structure is neat. The double-sided press-fit rivet joint structure has knurling on the outer surface of the insert and uses an interference fit, making the rivet structure more robust and reliable.

[0005] However, this does not solve the problem that existing riveting equipment of this type is generally not conducive to convenient sequential riveting work, which affects the feeding time between each group of busbars, and is not convenient for riveting in multiple moving positions. This affects the flexibility of the riveting equipment for riveting in multiple moving positions and the efficiency of riveting busbars. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a laminated busbar riveting device, comprising a base plate and a frame, a frame mounted on the top of the base plate, a transverse support mounted on the side wall of the frame, a longitudinal support disposed outside the transverse support, a riveting machine disposed outside the longitudinal support, a rivet movably mounted at the bottom end of the riveting machine, a sliding plate disposed outside the base plate, a servo motor mounted on the side wall of the base plate, a first threaded rod mounted at the output end of the servo motor, the first threaded rod extending to the outside of the base plate and movably connected thereto, the first...
