Description

Technical Field

[0001] This utility model relates to the field of riveting temperature measurement technology, specifically a general-purpose temperature inspection fixture for CCS. Background Technology

[0002] There are two main load-bearing modes for integrated busbars (CCS) of new energy batteries: one is injection-molded separator plate load-bearing, and the other is vacuum-formed separator plate load-bearing. Both load-bearing methods require the separator plate / aluminum busbar / FPC / NTC, etc. to be riveted together. In order to better control the temperature parameters of the riveting process, the temperature in the riveting process needs to be measured.

[0003] Previously, temperature measurement of rivet points in CCS hot riveting fixtures was done using handheld temperature probes / guns, which was very inefficient and inaccurate due to point-to-point measurement. While there are dedicated temperature measuring fixtures that correspond one-to-one between the temperature probe and the hot riveting point, solving the problem of inaccurate temperature measurement, these fixtures are complex in design and can only be used with specific models. Switching to different models requires redesigning the temperature measuring fixture, resulting in high costs. Therefore, there is a need to design a general-purpose temperature inspection fixture for CCS that supports fast and accurate temperature inspection. Utility Model Content

The detachable temperature measuring head 3 includes a base 31 and a pressure cap 32 installed on top of the base 31. A mounting cavity 321 is formed at the bottom of the base 31, and a through hole 322 communicating with the mounting cavity 321 is formed at the center of the bottom of the base 31. A spring-loaded head 33 is disposed inside the mounting cavity 321, and a temperature sensor 34 passing through the through hole 322 is fixedly connected to the top of the spring-loaded head 33. The bottom of the base 31 has a receiving groove, in which a magnet 36 is fixedly connected. The magnet 36 is attracted and fixed to the magnetic steel plate 2. In use, the riveted copper sheet presses down on the temperature sensor 34, which is used to measure the temperature at the riveting point. The detachable temperature measuring head 3 is attracted and fixed to the magnetic steel plate 2 by the magnet 36. The detachable temperature measuring head 3 is installed into the circular relief groove 11 to fix the position of the detachable temperature measuring head 3. The magnetic fixation method facilitates the quick assembly and disassembly of the detachable temperature measuring head 3, and the position of the detachable temperature measuring head 3 can be quickly changed. When matching CCS hot riveting fixtures of different models, only the acrylic positioning plate 1 needs to be replaced, and the detachable temperature measuring head 3 can continue to be used, which greatly reduces the manufacturing cost and is suitable for hot riveting temperature measurement of various models.

[0021] In this embodiment, as Figure 1 and Figure 2As shown, positioning posts 4 are fixedly connected to the four corners of the acrylic positioning plate 1. The positioning posts 4 are used for positioning and assembly with the streamlined carrier of the CCS hot riveting fixture, which facilitates the positioning and installation of the acrylic positioning plate 1.

[0022] In this embodiment, as Figure 4 As shown, a return spring 35 is provided inside the mounting cavity 321 and between the spring head 33 and the base 31. The top of the base 31 has a first limiting groove, and the bottom of the spring head 33 has a second limiting groove. The two ends of the return spring 35 are respectively placed inside the first limiting groove and the second limiting groove. The installation position of the return spring 35 is limited by the first limiting groove and the second limiting groove, and the return spring 35 is fixedly assembled inside the mounting cavity 321. The return spring 35 provides an upward thrust to the spring head 33 and the temperature sensor 34, so that the temperature sensor 34 is in stable contact with the copper sheet to be riveted, ensuring the accuracy of temperature measurement.

[0023] In this embodiment, as Figure 4 As shown, the top of the base 31 has multiple base connection holes 311 evenly spaced along the circumference, and the cover 32 has multiple cover connection holes 323 that pass through it.

The connecting blocks 38 are provided with anti-slip texture. The connecting blocks 38 facilitate the removal and assembly of the detachable temperature measuring head 3.

[0026] Working principle: In use, the acrylic positioning plate 1 is positioned and assembled with the streamlined carrier of the CCS hot riveting fixture via the positioning pin 4. The detachable temperature measuring head 3 is installed into the circular clearance groove 11 at the riveting point. The riveted copper sheet presses down on the temperature sensor 34, which measures the temperature at the riveting point. The return spring 35 provides an upward thrust to the spring head 33 and the temperature sensor 34, ensuring stable contact between the temperature sensor 34 and the copper sheet to be riveted, thus guaranteeing accurate temperature measurement. Furthermore, the detachable temperature measuring head 3 is fixed to the magnetic steel plate 2 by magnet 36. The detachable temperature measuring head 3 is installed into the circular relief groove 11 to fix the position of the detachable temperature measuring head 3. The magnetic fixation method facilitates the quick assembly and disassembly of the detachable temperature measuring head 3, and the position of the detachable temperature measuring head 3 can be quickly changed. When matching CCS hot riveting fixtures of different models, only the acrylic positioning plate 1 needs to be replaced, and the detachable temperature measuring head 3 can continue to be used, which greatly reduces the manufacturing cost and is suitable for hot riveting temperature measurement of various models.
