Description

Technical Field

[0001] This utility model relates to the field of battery cell sorting technology, specifically to an adjustable lithium battery cell sorting device. Background Technology

[0002] Lithium-ion battery cell sorting is a crucial step in the lithium-ion battery production process. Its purpose is to separate cells with similar or identical performance to ensure the overall performance and safety of the battery pack. Internal resistance is a key parameter of a battery cell, reflecting the conductivity of its internal components such as electrode materials, electrolyte, and separator, as well as the interfacial characteristics between the electrodes and electrolyte. By sorting cells with lower and more consistent internal resistance, the efficiency and stability of the battery pack during charging and discharging can be guaranteed, reducing the adverse effects of heat generation.

[0003] The sorting of internal resistance mainly involves testing the internal resistance of the battery cells. After testing, the cells are sorted according to their internal resistance values. Currently, most sorting devices have fixed and non-adjustable testing platforms. While this facilitates placing the battery cells for internal resistance testing, the sorting step requires the use of moving and clamping equipment. The battery cells are positioned, clamped, and then moved and adjusted to separate cells with high and low internal resistance, which is quite cumbersome. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides an adjustable lithium battery cell sorting device, comprising: a base plate 1, and a fixed frame 2 installed on the top of the base plate 1. An adjustment component 3 is installed on the inner wall of the fixed frame 2, and a detection platform 4 is rotatably installed on the top outer wall of the fixed frame 2. One end of the top of the adjustment component 3 is rotatably connected to the bottom of the detection platform 4. A placement frame 5 is fixed on the top outer wall of the base plate 1. A bending plate 6 is fixed on the top outer wall of the base plate 1, and an electric push rod 7 is fixedly inserted into the top outer wall of the bending plate 6. An installation frame 8 is installed at the bottom of the piston rod of the electric push rod 7, and an internal resistance tester 9 is installed on the top inner wall of the installation frame 8. Test components 10 are movably inserted into both outer walls of the installation frame 8, and both ends of the internal resistance tester 9 are connected to the two test components 10 through wires. A separator component 11 is installed on one outer wall of the piston rod of the electric push rod 7, and a conveyor belt 13 is installed at both ends of the top outer wall of the base plate 1.

[0020] It should be noted that multiple battery cells 14 can be placed in the placement frame 5. Under the action of gravity, the first battery cell 14 will roll into the testing table 4. At this time, the electric push rod 7 can drive the mounting frame 8 to descend, so that the separator component 11 is inserted on one side of the first battery cell 14, separating it from the other battery cells 14. Then, the electric push rod 7 continues to extend, driving the mounting frame 8 to descend a certain height, so that the two test components 10 are respectively attached to the two poles of the first battery cell 14. The internal resistance tester 9 is used to test the internal resistance of the battery cell 14. After the test, the electric push rod 7 can drive the mounting frame 8 to rise a certain height. At this time, the position of the separator component 11 is inconvenient. The two conveyor belts 13 can be set to transport battery cells with different internal resistances. At this time, according to the test results, the horizontal state of the testing table 4 can be adjusted by adjusting the component 3, so that the testing table 4 is tilted, and the battery cells 14 on the testing table 4 automatically slide down to the corresponding conveyor belt 13 and are directly transferred to the next processing station. There is no need to use complicated clamping and shifting devices to sort the battery cells 14, which is more convenient.

[0021] In a preferred embodiment, the adjustment assembly 3 includes a motor 301, a threaded rod 302 mounted on the output shaft of the motor 301, a slider 303 screwed onto the threaded rod 302, and a connecting rod 304 rotatably connected to the outer wall of one side of the slider 303; the top of the connecting rod 304 is rotatably connected to the bottom of the detection table 4.

[0022] It should be noted that: the motor 301 can drive the threaded rod 302 to rotate, which in turn drives the slider 303 to rise or fall, and then drives one end of the detection table 4 to rise or fall through the connecting rod 304, thereby adjusting the horizontal state of the detection table 4.

[0023] In a preferred embodiment, the test assembly 10 includes a first rod 1001, a detection patch 1002 mounted on one end of the first rod 1001, and a first spring 1003 sleeved on the outside of the first rod 1001.

[0024] It should be noted that during the descent of the mounting frame 8, the detection patch 1002 can contact the electrode of the battery cell 14 and drive the first rod 1001 to move, squeezing the first spring 1003. The reaction force of the first spring 1003 can press the detection patch 1002 onto the electrode.

[0025] In a preferred embodiment, the partition assembly 11 includes a mounting plate 1101, a second rod 1102 movably inserted into one end of the top of the mounting plate 1101, a second spring 1103 sleeved on the outside of the second rod 1102, and a partition 1104 installed at the bottom of the second rod 1102.

[0026] It should be noted here that: the electric push rod 7 drives the mounting frame 8 to descend, which in turn drives the partition 1104 to descend, so that the partition 1104 is inserted into one side of the first battery cell 14, separating it from the other battery cells 14. At this time, the piston rod of the electric push rod 7 drives the mounting frame 8 to continue to descend, while driving the mounting plate 1101 to descend and compress the second spring 1103, while the partition 1104 remains stationary.

[0027] In a preferred embodiment, connecting brackets 12 are installed on both sides of the top outer wall of the base plate 1.

[0028] It should be noted that this can serve as a connection between the testing station 4 and the conveyor belt 13.

[0029] Working principle: Multiple battery cells 14 can be placed in the placement frame 5. Under the action of gravity, the first battery cell 14 will roll into the testing stage 4. At this time, the electric push rod 7 can drive the mounting frame 8 to descend, which can drive the partition plate 1104 to descend, so that the partition plate 1104 is inserted on one side of the first battery cell 14, separating it from the other battery cells 14. At this time, the piston rod of the electric push rod 7 drives the mounting frame 8 to continue to descend, and at the same time drives the mounting plate 1101 to descend and squeeze the second spring 1103. The partition plate 1104 remains stationary. During the descent of the mounting frame 8, the detection patch 1002 can contact the electrode of the battery cell 14 and drive the first rod 1001 to move, squeezing the first spring 1003. The reaction force of the first spring 1003 can press the detection patch 1002 onto the electrode. The internal resistance tester 9 is used to test the internal resistance of the battery cell 14.

[0030] After testing, the mounting frame 8 can be raised to a certain height by the electric push rod 7. At this time, the position of the partition 1104 is inconvenient. The two conveyor belts 13 can be used to transport the battery cells with different internal resistances. According to the test results, the threaded rod 302 can be rotated by the motor 301, which in turn drives the slider 303 to rise or fall. Then, the connecting rod 304 drives one end of the test table 4 to rise or fall, adjusting the horizontal state of the test table 4 so that the test table 4 is tilted, and the battery cell 14 on the test table 4 automatically slides down to the corresponding conveyor belt 13 and is directly transferred to the next processing station. There is no need to use complicated clamping and shifting devices to sort the battery cell 14, which is more convenient.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
