During the production process of batteries, it is necessary to detect the voltage and internal resistance of the batteries. In the existing voltage and internal resistance detection mechanism, during detection, two adjacent sets of tab ears on the battery are likely to come into contact with each other due to bending, resulting in battery short circuit, affecting the accuracy of the detection results, and even easily causing damage to the detection equipment. Therefore, it is necessary to make a voltage and internal resistance testing mechanism to solve the above problems. Summary of the Utility Model

The second detection probe component 9 corresponds to the upper right side of the partition ribs 61. The distance adjustment driving component 7 drives the second detection probe component 9 to move left and right.

[0017] In the current process, the battery is transported to the voltage internal resistance testing mechanism. The tab on the battery corresponds to the upper part of the carrier 6. The transverse movement driving component 1 drives the transverse movement support 2 to move left and right, so that the partition ribs 61 are located below the two groups of tabs on the battery. The lifting driving component 3 drives the lifting slide plate 5 to rise on the lifting slide 4, so that the upper end surface of the carrier 6 corresponds to the bottom of the tab, and the partition ribs 61 correspond to the two groups of tabs. Then, the distance adjustment driving component 7 adjusts the distance between the second detection probe component 9 and the first detection probe component 8 according to the positions of the two groups of tabs on the battery. Then, the first detection probe component 8 and the second detection probe component 9 press the two groups of tabs on the battery onto the carrier 6 respectively, and perform voltage internal resistance testing on the battery. The advantage of this design is that the partition ribs 61 are provided, which can prevent the two groups of tabs on the same battery from touching each other, avoid battery short circuit caused by tab touch, prevent damage to the battery and the detection equipment, and improve the accuracy and stability of detection.

The transverse movement slide plate 75 is fixed to the connecting block 73 and is slidably connected to the transverse movement slide 74. The second detection probe component 9 is fixed to the transverse movement slide plate 75.

[0019] When it is necessary to adjust the distance between the second detection probe assembly 9 and the first detection probe assembly 8, the rotation motor 71 drives the screw 72 to rotate, so as to drive the transverse movement slide plate 75 to move left and right on the transverse movement slide table 74 through the connecting block 73, thereby adjusting the position of the second detection probe assembly 9.

[0020] The first detection probe assembly 8 includes a first pressing cylinder 81 and a first probe 82. The first pressing cylinder 81 is fixed on the transverse movement support 2. The upper end of the first probe 82 is fixed to the power output end of the first pressing cylinder 81, and the lower end corresponds to the upper left side of the partition rib 61.

The upper end of the second probe 92 is fixed to the power output end of the second pressing cylinder 91, and the lower end corresponds to the upper right side of the partition rib 61.
