Description

Technical Field:

[0001] The utility model relates to a flexible manual cell sorting mechanism, belonging to the technical field of new energy battery cells. Background Art:

[0002] The existing cell sorting mechanism is an automated device connected to the entire production line. The voltage and internal resistance tester is placed on the frame of the production line flow channel. The cells flow from the front end to the back. When the cell flows to the designated position from the production line flow channel, the cylinder drives the probe of the voltage and internal resistance tester to press on the positive and negative electrodes of the cell, thereby measuring the internal resistance and voltage of the cell. After measurement, the cell flows backward along the production line flow channel.

[0003] The following defects exist in the prior art:

[0004] 1. Since the voltage and internal resistance tester is installed on the production line, the flexibility of the test location is limited;

[0005] 2. Since the probe is fixed on the tooling of the cylinder, the cell model cannot be switched at any time;

[0006] 3. After the cell sorting mechanism is worn, it needs to be completely replaced, resulting in too high cost;

[0007] 4. The measurement success rate is poor, affecting the production rhythm.

[0029] The following further describes the utility model with reference to the drawings.

[0030] The flexible manual cell sorting mechanism of the utility model includes a rocking handle 1, a first flange linear bearing 2, a top support block 3, a ground ball screw 4, a linear bearing 5, a fixing block 6, a quick clamp 7, a probe fixing block 8, a connecting plate 9, a pressing plate 10, a supporting block 11, a spring (not shown), a bottom support block 14, a long guide shaft 15, a test probe 16, a support seat 17, a limiting plate 18, a cell 19, a short guide shaft 22 and a second flange linear bearing.

[0031] The first flange linear bearing 2 includes a base portion 20 and an extension portion 21 connected to the base portion 20. The base portion 20 of the flange linear bearing 2 is fixed on the top support block 3, and the extension portion 21 of the flange linear bearing 2 is located below the rocking handle 1.

[0032] The upper end of the ground ball screw 4 passes through the first flange linear bearing 2 and is fixedly connected to the rocking handle 1. The first flange linear bearing 2 can fix the direction of the ground ball screw 4 and reduce the rotational friction of the ground ball screw 4.

[0033] The lower end of the grinding ball screw 4 passes through the fixed block 6 and extends below the fixed block 6, and the grinding ball screw 4 is connected to the bottom support block 14 through a pedestal bearing (not shown). A profile 24 is connected between the top support block 3 and the bottom support block 14.

[0034] The long guide shaft 15 passes through the fixed block 6 and its upper end is fixed to the top support block 3. A linear bearing 5 is sleeved outside the long guide shaft 15, and the linear bearing 5 is used to fix the moving direction of the long guide shaft 15.

[0035] The quick clamp 7 is fixed to one side surface of the fixed block 6 by bolts, and a connecting plate 9 is connected to the lower end of the quick clamp 7. The quick clamp 7 includes a wrench 70. By the movement of the wrench 70, the connecting plate 9 fixedly connected to the quick clamp 7 can be driven to move up and down with the quick clamp 7, thereby driving the probe fixing block 8 to move up and down with the connecting plate 9, and the test probe 16 to move up and down with the probe fixing block 8.

[0036] The short guide shaft 22 passes through the connecting plate 9 and is located on both sides of the quick clamp 7. A second flange linear bearing (not marked) is sleeved outside the short guide shaft 22, and the second flange linear bearing is fixed to the connecting plate 9. A spring is sleeved on the short guide shaft 22 below the connecting plate 9.

[0037] The support block 11 is installed together with the lower end of the short guide shaft 22, and the support block 11 is used to support the short guide shaft 22.

[0038] The pressing plate 10 includes two pieces located on both sides of the fixed block 6. Each pressing plate 10 on each side is connected to the fixed block 6 and the support block 11 on that side by bolts.

[0039] The probe fixing blocks 8 are fixedly spaced on the connecting plate 9 at a position away from the fixed block 6. The test probe 16 is fixed on the probe fixing block 8. The test probe 16 is located above the battery cell 19.

[0040] The bottom support block 14 and the battery cell 19 are both supported on the support base 17, and a limiting plate 18 is fixed on the support base 17 and at a position on one side of the battery cell 19.

[0041] The working principle of the flexible manual battery cell sorting mechanism of the present utility model is as follows:

[0042] The movement of the wrench 70 can drive the connecting plate 9 fixedly connected to the quick clamp 7 to move downward along with the quick clamp 7, thereby driving the probe fixing block 8 to move downward along with the connecting plate 9, and the test probe 16 to move downward along with the probe fixing block 8. As the probe fixing block 8 moves downward, the test probe 16 contacts the positive and negative electrodes of the battery cell 19. The test probe 16 is externally connected to a battery tester through a wire harness. The battery tester contacts the positive and negative electrodes of the battery cell 19 through the test probe 16, so as to measure the voltage and internal resistance of the battery cell, and then upload the voltage and internal resistance to the computer through a communication cable, and further classify the battery cells according to the values of the voltage and internal resistance. The method by which the battery tester measures the voltage and internal resistance of the battery cell through the test probe is common general knowledge in the art and will not be elaborated here.

[0043] After the measurement, the upward elastic force of the spring 12 sleeved on the short guide shaft 22 and the movement of the wrench 70 cause the quick clamp 7 to drive the connecting plate 9 to move upward, so that the test probe 16 moves away from the positive and negative electrodes of the battery cell 19, so that a new battery cell can be replaced for measurement.

[0044] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be regarded as the protection scope of the present invention.
