When the receiving platform 62 is in a horizontal state, the lowest point inside the rotating cylinder 31 is in the same plane as the lowest point of the receiving groove 622. The interior of the rotating cylinder 31 is provided with a limiting ring 312. The end of the sliding block 4 close to the clamping block 3 is symmetrically penetrated with a detection needle 42 for detecting the positive and negative poles of the battery (and because the positive pole of the battery has a protrusion, the detection needle 42 for detecting the positive pole of the battery is shorter than the detection needle 4 for detecting the negative pole of the battery). 2), the detection needles 42 on the two sliding blocks 4 correspond to each other, and the connection lines of the detection needles 42 on the two sliding blocks 4 are all inserted into the fixed frame 2, the detection component used in conjunction with the detection needle 42 is fixed on the fixed frame 2, and then the connection line of the detection needle 42 is connected, and the detection needle 42 can be used.

The negative electrode of the battery can be used to determine the performance of the battery by using a detection component used in conjunction with the detection needle 42. The method of using the detection needle 42 to detect the battery is a mature existing technology. For example, the patent with application number CN202311042518.7 discloses in detail the use of the detection needle, so it will not be repeated in this application). The limiting ring 312 is provided with an avoidance hole 313 that allows the detection needle 42 or the protrusion of the positive electrode of the battery to pass through. A fixing plate 22 is provided on the side of the receiving platform 62 away from the base 1. The fixing plate 22 is connected to the fixing frame 2 through a support column 221.

A driven gear 311 is provided on the outside of the rotating cylinder 31 inside the clamping block 3. The driven gears 311 are all rotatably connected to the inside of the clamping block 3, and the two driven gears 311 are meshed with each other. The driven gear 311 close to the driving gear 32 meshes with the driving gear 32; turn on the third driving member 321, the third driving member 321 drives the driving gear 32 to rotate, and the driving gear 32 drives the two driven gears 311 to rotate, thereby driving the two rotating cylinders 31 to rotate.

[0037] See also Figures 1 to 6 Preferably, an anti-slip pad (such as a rubber pad) is provided on the inner wall of the rotating cylinder 31. When the rotating cylinder 31 is used to drive the battery to rotate, the anti-slip pad can increase the friction between the rotating cylinder 31 and the battery, ensuring that the battery can rotate with the rotating cylinder 31.

[0038] See also Figures 1 to 6 Preferably, a fixed cylinder 41 is slidably provided inside the side of the sliding block 4 away from the clamping block 3 (insertion blocks are symmetrically provided on the fixed cylinder 41 inside the sliding block 4, and slots matching the insertion blocks are symmetrically provided on the inner wall of the sliding block 4, and the insertion blocks are slidably set in the slots), and the end of the fixed cylinder 41 away from the clamping block 3 is connected to the fixed frame 2, and the connecting wires of the detection needle 42 pass through the fixed cylinder 41 and then penetrate into the fixed frame 2.

[0042] See also Figures 1 to 6 When performing surface defect inspection on the battery, the receiving platform 62 is placed in a horizontal state, the battery is placed in the placement groove 621, and then the card plate 64 is moved to the side close to the placement groove 621 until the card plate 64 is close to one end of the battery and abuts the battery, thus completing the fixation of the battery. Then, by rotating the receiving platform 62, the battery is driven to rotate, and the positive and negative ends of the battery can be inspected through the detection element for surface defect inspection of the battery on the fixing plate 22. After the inspection is completed, the receiving platform 62 is placed in a horizontal state, the card plate 64 is rotated so that the card plate 64 is exactly located between the two placement grooves 621, and the card plate 64 is lifted and lowered to make it enter the storage groove 622.

Both ends of the battery are located in the rotating cylinder 31, and the protrusion of the positive electrode of the battery just passes through the avoidance hole 313. The rotating cylinder 31 is rotated, and the battery is slowly rotated by the rotating cylinder 31. The detection element for surface defect detection of the battery on the fixed plate 22 can be used to detect the periphery of the battery except the positive and negative electrodes.

[0044] When testing the performance of the battery, the receiving platform 62 is placed in a horizontal state, the two clamping blocks 3 are brought close to each other, both ends of the battery are located in the rotating cylinder 31, and the protrusion of the positive electrode of the battery just passes through the avoidance hole 313. The sliding block 4 is moved so that one end of the testing needle 42 abuts the positive or negative electrode of the battery. The performance of the battery can then be tested using the testing component connected to the testing needle 42.

[0045] After the test is completed, the receiving platform 62 is rotated, the card plate 64 is retracted, and the tested battery is released into the groove 11. The inclined surface in the groove 11 can facilitate the battery to roll to one side until it is removed from the base 1.

[0046] The present invention provides an automated battery testing device, including a clamping block and a sliding block. By using the rotating cylinder and receiving platform on the clamping block to cooperate with each other, the battery can be quickly fixed.
