Description

Technical Field

[0002] With the continuous development of battery technology, battery modules are being used in more and more applications, such as energy storage, automobiles, and drones. During the production process of battery modules, due to the large size of individual batteries, a large installation space is required during the battery installation process. Therefore, during the battery assembly process, the battery modules are formed by connecting the batteries together and then installed as a whole. This can save battery installation space and eliminate the need for complex wiring harnesses to connect multiple batteries. After the battery assembly is completed, it needs to undergo various performance tests, such as charge and discharge testing, voltage, and internal resistance testing, to ensure that they meet factory requirements. Currently, the voltage and internal resistance of battery modules are mainly tested manually, which has high labor costs and requires the battery modules to be moved and transferred. The test end of the battery module is then tested by external testing equipment, which is risky and does not meet the company's needs for high-quality production. Alternatively, the battery module is moved to a test machine by an external robot, and then another set of robots performs needle testing. The voltage and internal resistance test machines are different, so synchronous testing is impossible, resulting in low efficiency. If a battery module testing tool with a simple structure, precise positioning, and the ability to simultaneously detect the voltage and internal resistance of the battery module can be designed, the above problems can be solved.

[0021] like Figures 1 to 6As shown, in this embodiment, the utility model includes a carrier assembly 1 and a pressing assembly 2, characterized in that: the carrier assembly 1 includes a sliding support module 3, a carrier 4 and a lifting module 5, the movable end of the lifting module 5 cooperates with the carrier 4 at the upper end of the sliding support module 3, the pressing assembly 2 includes a pressing bracket 7, a pressing module 8 and a probe module 9, the probe module 9 includes a pressing connecting plate 91, an insulating probe supporting plate 92 and a probe 93, several of the insulating probe supporting plates 92 are connected to the lower end surface of the pressing connecting plate 91, two groups of the probes 93 are respectively arranged at both ends of the insulating probe supporting plate 92, the pressing module 8 is arranged in the middle of the pressing bracket 7, the movable end of the pressing module 8 is connected to the upper end of the pressing connecting plate 91, and the pressing module 8 drives the probes 93 at both ends of several of the insulating probe supporting plates 92 to cooperate with the voltage end and the internal resistance end of the battery module 10 at the upper end of the carrier 4. It can be seen that the carrier assembly 1 is arranged between the two groups of conveying mechanisms, the pressing assembly 2 is arranged at the upper end of the carrier assembly 1, and when the carrier 4 enters the middle of the upper end of the sliding support module 3, the lifting module 5 lifts it up, and the pressing module 8 drives the probe module 9 to press down. The insulating probe support plate 92 is made of insulating material, and the probes 93 at both ends will not affect each other, and can be respectively connected to the voltage end and the internal resistance end of the battery module 10.

[0022] like Figure 2 As shown, in this embodiment, the sliding support module 3 includes a sliding support plate 31 and a supporting cross plate 32. Two sets of the sliding support plates 31 are connected by a plurality of supporting cross plates 32. The upper ends of the two sets of sliding support plates 31 are respectively provided with a carrier plate sliding groove 33 on the corresponding side. The carrier plate 4 slides in the carrier plate sliding groove 33. As can be seen, the carrier plate sliding groove 33 enables the carrier plate 4 to smoothly enter the middle of the upper end of the sliding support plate 31, preventing deviation during the lifting process.

[0023] like Figure 2 and Figure 6As shown, in this embodiment, the jacking module 5 includes a cylinder support plate 51, a jacking plate 52 and a jacking cylinder 53. The two ends of the two groups of cylinder support plates 51 are respectively connected to the lower ends of the two groups of sliding support plates 31. The two groups of cylinder support plates 51 are connected to the jacking plates 52 through a number of jacking linear bearings 54. The two groups of jacking cylinders 53 are arranged in the middle of the lower end surfaces of the two groups of cylinder support plates 51. The movable ends of the two groups of jacking cylinders 53 are connected to the lower end surfaces of the jacking plates 52. The two groups of jacking cylinders 53 drive the jacking plates 52 to cooperate with the lower end surfaces of the carrier plate 4. It can be seen that the jacking cylinders 53 drive the jacking plates 52 to rise, separate the carrier plate 4 from the sliding support module 3, and provide a stable and independent downward pressure test environment. In addition, the provision of two groups of jacking cylinders 53 makes the jacking force more uniform and avoids deviation during the jacking process.

[0024] like Figure 4 and Figure 5 As shown, in this embodiment, the pressing module 8 includes a pressing support plate 81 and a pressing cylinder 82. The pressing support plate 81 is arranged in the middle of the pressing bracket 7. The pressing support plate 81 is connected to the pressing connection plate 91 through a plurality of pressing linear bearings 83. The pressing cylinder 82 is arranged in the middle of the upper end of the pressing support plate 81. The movable end of the pressing cylinder 82 is connected to the upper end of the pressing connection plate 91. It can be seen that after the pressing cylinder 82 completes the lifting, it drives the probe module 9 to descend and connects the plurality of probes 93 to the voltage terminal and the probe terminal on the battery module 10.

[0025] like Figure 5 As shown, in this embodiment, a plurality of probe connection holes 84 are provided on both sides of the pressing support plate 81. The connection end of the external test module is connected to the probes 93 on both sides of the insulating probe support plate 92 through the probe connection holes 84. As can be seen, the wiring harness is organized through the plurality of neatly arranged probe connection holes 84, which ensures that the entire pressing mechanism is more stable and the plurality of wiring harnesses do not interfere with the pressing process.

[0026] like Figure 1 and Figure 4 As shown, in this embodiment, the upper end of the pressing bracket 7 is provided with an operation panel 11 and several protective side panels 12. The protective side panels 12 are provided with several wiring harness openings 13. The external test module cooperates with the several probe connection through-holes 84 through the several wiring harness openings 13. The upper end of the pressing bracket 7 is also provided with a protective top plate 17. As can be seen, the several wiring harness openings 13 can evenly organize the wiring harnesses on the several probe connection through-holes 84 and connect them to the external test equipment.

[0027] like Figure 2 and Figure 3 As shown, in this embodiment, a limit plate 14 is provided in the middle of the upper end surface of the carrier plate 4, and limit blocks 15 are provided at both ends of the upper end surface of the limit plate 14. The ends of the battery module 10 are engaged with the limit blocks 15 at both ends of the limit plate 14. Thus, the limit blocks 15 can fix the battery module 10 in the middle of the carrier plate 4 to prevent displacement during lifting or pressing.

[0028] like Figure 2 and Figure 3 As shown, in this embodiment, sliding rollers 16 are provided at each of the four diagonal corners of the carrier plate 4, and several of the sliding rollers 16 cooperate with the carrier plate sliding groove 33. Thus, the sliding rollers 16 reduce the sliding resistance of the carrier plate 4 in the carrier plate sliding groove 33, preventing the battery module 10 from shifting due to jamming during sliding.

[0029] like Figure 1 As shown, in this embodiment, an indicator plate 18 is further provided on one side of the sliding support module 3. Thus, the indicator plate 18 can be used to paste production process information, etc., which can effectively avoid equipment failure caused by misoperation.

[0030] like Figure 2 and Figure 6 As shown, in this embodiment, the upper end surface of the lifting plate 52 is provided with a plurality of positioning guide pins 19, and the lower end surface of the carrier plate 4 is provided with a plurality of positioning guide sleeves 20. The plurality of positioning guide pins 19 and the plurality of positioning guide sleeves 20 cooperate with each other. It can be seen that the plurality of positioning guide sleeves 20 and the plurality of positioning guide pins 19 achieve precise positioning before lifting, preventing inaccurate positioning during the needle insertion process.

[0031] The working principle of the present utility model is as follows: before the equipment is started, the conveying mechanism at the feeding end of the sliding support module 3 pushes the carrier plate 4 equipped with the battery module 10 into the middle of the sliding support module 3, and several of the lifting cylinders 53 drive the lifting plate 52 to rise, and several of the positioning guide pins 19 and several of the positioning guide sleeves 20 cooperate to make the carrier plate 4 fall accurately on the lifting plate 52, and the lifting plate 52 lifts the carrier plate 4 to the test position, and the pressing cylinder 82 drives the pressing connecting plate 91 to descend, and several groups of the absolute pressure at the bottom of the pressing connecting plate 91 are pressed down. The probes at both ends of the edge probe support plate 92 are respectively connected to the voltage ends and internal resistance ends of several batteries on the battery module 10. After the needle is lowered, a power-on test is performed. After the test is completed, the downward pressure cylinder 82 drives the downward pressure connecting plate 91 to rise, and several of the lifting cylinders 53 drive the lifting plate 52 to descend. The conveying mechanism at the unloading end of the sliding support module 3 takes away the carrier plate 4 that has been tested, and the conveying mechanism at the loading end of the sliding support module 3 pushes in a new carrier plate 4. Repeating the above steps can realize the synchronous detection of the battery module voltage and internal resistance.

[0032] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
