Description

Technical Field

[0001] The utility model relates to the field of power battery molds, in particular to a CCS assembly auxiliary tooling. Background Art

[0002] The traditional installation method of CCS components mainly relies on manual operation, which is not only time-consuming and laborious, but also prone to inaccurate installation positions, thus affecting the overall performance of the CCS system. Especially when dealing with the fixation and positioning of pressure collection points and temperature sensors, the operation difficulty is relatively large, installation deviations are likely to occur, and interference between the temperature collection points and the welding copper sleeves of the battery cells appears. When using thermal conductive glue coating in the existing installation method, it is often impossible to ensure the uniformity and accuracy of the coating. The coating quality of the thermal conductive glue is directly related to the working performance of the temperature sensor and the cooling effect of the CCS system. Manual operation is difficult to ensure the consistency of the coating, affects the heat dissipation efficiency of the system, and has too high a cost. Content of the Utility Model

[0024] Embodiment 1

[0025] As Figure 1-2A CCS assembly auxiliary tooling as shown, which includes a main body bracket 1. The main body bracket 1 includes a pair of outer brackets 11. A pressure collection point fixing group 2 is provided at the lower end of the outer brackets 11. Through the pressure collection point fixing group 2, interference between the cell welding copper sleeve after pressure collection point gluing is avoided during the CCS assembly process. The main body bracket 1 further includes an inner bracket 12. The inner bracket 12 is located between the pair of outer brackets 11. A sensor auxiliary fixing group 3 is provided at the lower end of the inner bracket 12. The sensor auxiliary fixing group 3 presses the thermal conductive glue during the CCS assembly to avoid stress protrusions during the temperature sensor gluing, thus preventing the problem of insecure curing of the thermal conductive glue.

[0026] In some implementation manners, both the outer brackets 11 and the inner bracket 12 are metal structural parts;

[0027] Optionally, the outer brackets 11 and the inner bracket 12 can adopt corrosion-resistant metal materials (stainless steel, aluminum alloy), so that the outer brackets 11 and the inner bracket 12 are not easily corroded by external conditions during use, and the service life of the outer brackets 11 and the inner bracket 12 is prolonged.

[0028] In some implementation manners, the pressure collection point fixing group 2 is composed of a number of pressure collection point fixing devices 21. The pressure collection point fixing device 21 includes a vertical connecting rod 211. One end of the vertical connecting rod 211 is connected to the outer bracket 11, and the other end is connected with a pressing head 212. The pressing head 212 can accurately locate the position of the pressure collection point gluing during the CCS assembly, enabling the operator to accurately identify the gluing position and avoiding interference between the gluing position being too random and the cell welding copper sleeve;

[0029] As Figure 1-2 shown, the sensor auxiliary fixing group 3 and the pressure collection point fixing group 2 are plastic structural parts;

[0030] Optionally, the sensor auxiliary fixing group 3 and the pressure collection point fixing group 2 can be made of rubber parts. Since the rubber parts are light in weight and low in cost, the tooling is more portable in scenarios where frequent movement and use are required. At the same time, due to the low cost of the rubber parts, the subsequent maintenance and replacement costs of the tooling can be reduced.

[0031] In some implementation manners, the main body of the vertical connecting rod 211 is a telescopic rod structure, so that the vertical connecting rod 211 can be adjusted between different heights. By adjusting the height, the tooling can be used in occasions with different heights, facilitating the tooling to be used in multiple scenarios.

[0032] In some implementation manners, a horizontal connecting rod 13 is provided between the outer brackets 11. The horizontal connecting rod 13 is connected to the inner bracket 12. Such a setting can ensure the structural stability of the main body bracket 1.

[0033] As shown Figure 2-3 In the figure, a sensor-assisted fixing group 3 is provided at the lower end of the inner bracket 12, and the sensor-assisted fixing group 3 includes a plurality of sensor fixing devices 31. The sensor fixing device 31 includes a fixing clamp 311 which can fix the temperature sensor during glue application to prevent the temperature sensor from bulging due to stress during glue application. A guiding groove 312 is provided on the fixing device, and the guiding groove 312 can ensure the uniformity of glue application.

[0034] In some implementation manners, the diameter of the pressing head (212) is larger than the cross-sectional diameter of the vertical connecting rod (211). Such a setting enables the pressing head (212) to apply more uniform and effective pressure. The larger contact surface helps to apply uniform pressure over a larger area, thereby improving the pressing effect.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
