Description

Technical Field

[0001] The present application relates to the technical field of integrated busbar installation and positioning, and specifically, to a positioning tool and a positioning system for an integrated busbar. Background Art

[0002] In recent years, the new energy electric vehicle industry has flourished, and the power battery technology, as the core of new energy vehicle power, has also been continuously improving. As one of the key components of new energy battery packs, the materials and integration processes of the integrated busbar (Cells Contact System, CCS) are also constantly developing in the direction of high safety, high integration, lightweight, and low cost. New energy batteries are generally composed of multiple battery modules, and each battery module is equipped with a set of CCS. It is connected into a whole through a hot pressing process to realize the high-voltage series and parallel connection of the battery cells, as well as the temperature sampling and battery voltage sampling functions of the battery, and provide temperature and voltage to the battery management system (Battery Management System, BMS) through a flexible printed circuit board (Flexible Printed Circuit Board, FPC) / printed circuit board (Printed Circuit Board, PCB) and connector components.

[0003] In the production process of CCS integrated busbars, welding equipment is one of the indispensable equipment. Welding is the process of connecting two separated workpieces together by heating or pressurizing. In the production process of CCS integrated busbars, the welding method mainly involves polymer diffusion welding. Polymer diffusion welding is a welding method that keeps the closely contacted weldments at a certain temperature and pressure for a period of time so that the atoms between the contact interface diffuse with each other to achieve a reliable connection. The existing CCS pre-welding positioning method is to use masking tape for positioning; the disadvantage is that it is inconvenient for personnel to operate, the equipment cannot perform automatic functions, and additional materials are required, which increases the workload of employees. In addition, the process of removing the masking tape after fixing with masking tape is cumbersome and the masking tape cannot be reused, which increases the manufacturing cost. The residual glue may affect the subsequent welding quality.

[0004] In summary, the existing welding process has technical problems such as inconvenient positioning operation, insufficient automation, and high production cost, which affect the welding quality. Utility Model Content

[0036] In view of the shortcomings of the existing methods, the present application proposes a positioning tool 1 and a positioning system for an integrated busbar 3 to solve the technical problems of the prior art, such as inconvenient positioning operation, insufficient automation, high production cost, and poor welding quality.

[0038] A positioning tool 1 for an integrated busbar 3 includes a base 11, a spring limiting pressure plate 12, a support column 13, a limiting fixing sheet 14, a busbar fixing pressure plate 15 and a spring 16:

[0039] Base 11;

[0040] A spring limiting pressure plate 12 is arranged opposite to the base 11;

[0041] A support column 13, both ends of which are connected to the base 11 and the spring limit pressure plate 12 respectively;

[0042] A limiting fixing sheet 14 is sleeved on the periphery of the supporting column 13;

[0043] The busbar fixing plate 15 is sleeved on the periphery of the support column 13 and is located on a side of the limiting fixing plate 14 away from the base 11;

[0044] The spring 16 is sleeved on the periphery of the support column 13 and two ends thereof are respectively in contact with the spring limiting pressure plate 12 and the busbar fixing pressure plate 15 .

[0045] The embodiment of the present application adopts the positioning fixture 1 of the integrated busbar 3 for positioning. Compared with the positioning by masking tape, the positioning fixture can be reused, and the positioning and fixing method is changed to improve labor efficiency; the positioning fixture is simple to design and manufacture, and the one-time use of masking tape is reduced to reduce costs; the use of the positioning fixture can effectively avoid the residual glue. It is conducive to improving the quality of the finished product in the subsequent process; the busbar fixing plate 15 in the positioning fixture can move along the height direction on the support column 13 with the different lengths of the spring 16, so that the adjustable positioning fixture is compatible with integrated busbars 3 of different specifications.

[0046] In some embodiments of the present application, the limiting fixing plate 14 has a first through hole, the support column 13 passes through the first through hole, the limiting fixing plate 14 is slidably connected to the support column 13, and the moving direction of the limiting fixing plate 14 is parallel to the axial direction of the support column 13.

[0047] In this embodiment, the limiting fixing sheet 14 defines the lower travel limit of the busbar fixing pressure plate 15 , provides a supporting force for the busbar fixing pressure plate 15 , and prevents the spring 16 from being in a continuously stretched state, causing the spring 16 to fail.

[0049] In this embodiment, the busbar fixing plate 15 can move along the height direction on the support column 13 with different lengths of the spring 16, so as to be compatible with integrated busbars 3 of different specifications. Correspondingly, the limiting fixing plate 14 can also move along the height direction on the support column 13. Unlock the fixing plate limiting screw 17, and the limiting fixing plate 14 can move.
