Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery cell production technology, and in particular to a battery cell testing and sorting machine. Background Technology
[0002] In existing battery cell testing methods, the conveying device is stopped, and the battery cells are then manually tested using testing equipment. After testing, the battery cells are sorted. Because the existing method requires pausing the conveying device before testing and sorting, the testing and sorting efficiency is low. Therefore, a battery cell testing and sorting machine is proposed. Utility Model Content
[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides a battery cell testing and sorting machine, comprising: a base plate, a top plate, a synchronous pulley bracket, synchronous pulleys, and a synchronous belt. The synchronous pulley bracket is installed between both sides of the base plate and the top plate, and synchronous pulleys are provided at both ends of the synchronous pulley bracket. A synchronous belt is provided on each of the two synchronous pulleys on the same side, and a testing channel for clamping and advancing the battery cell is formed between the synchronous belts on both sides. Several testing components are respectively fixed on the base plate and the top plate at the top and bottom of the testing channel.
[0004] Furthermore, the timing belt has a tensioning assembly fixed to the base plate inside.
[0005] Furthermore, the tensioning assembly includes two upright plates fixed to the base plate, with springs fixedly connected to the inner surfaces of the upright plates, and rollers abutting against the timing belt at the other end of the springs.
[0006] Furthermore, several shrinkage holes are evenly provided in the middle of the upper surface of the base plate and the middle of the lower surface of the top plate. The detection component is installed inside the shrinkage hole. The detection component includes a spherical sleeve that is movably connected inside the shrinkage hole. The spherical sleeve has a cylindrical structure. The bottom end of the spherical sleeve is rotatably connected to a metal ball that abuts against the electrodes at both ends of the battery cell through a spherical hole.
[0007] Furthermore, a disc spring is fixedly connected between the inner end of the spherical sleeve and the inner end of the contraction hole.
[0008] Furthermore, the spherical sleeve, metal ball, and disc spring are all made of conductive materials and are connected to the electrical signals of the detection host.
[0009] Furthermore, the synchronous belt is driven by a servo motor and a reducer, and the two synchronous pulleys on the same end are driven by gear meshing. Beneficial effects
[0010] Two synchronous belts clamp the battery cells fed into the testing channel, and at the same time drive the battery cells to move forward synchronously. During the forward movement of the battery cells, the testing components at the top and bottom of the testing channel continuously test the battery cells.
[0011] When the battery cell is being tested inside the testing channel, the electrodes at both ends of the battery cell are simultaneously connected to the testing component. The metal ball makes contact with the electrodes, and the battery cell is tested based on the discharge status of the two electrodes. The metal ball allows the battery cell to move forward without affecting the connection between the metal ball and the battery cell electrodes, enabling continuous feeding and testing without interruption. When the metal ball contacts the current battery cell, the battery cell continues to move forward, making contact with the metal ball of the next testing component, and the next battery cell enters the testing area.
[0012] When the tensioning assembly is tensioning, the spring force pushes the roller to press the timing belt, so that the timing belt is tightened and pressed against the outer wall of the battery cell.
[0013] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation
[0021] Please refer to Figures 1 to 6 ;
[0022] This embodiment provides a battery cell testing and sorting machine, referencing... Figure 1 It includes: a base plate 1, a top plate 2, a synchronous pulley bracket 3, a synchronous pulley 4, and a synchronous belt 5. A synchronous pulley bracket 3 is installed between both sides of the base plate 1 and the top plate 2. A synchronous pulley 4 is provided at both ends of the synchronous pulley bracket 3. A synchronous belt 5 is provided on the two synchronous pulleys 4 on the same side. A detection channel for clamping the battery cell forward is formed between the synchronous belts 5 on both sides. Several detection components 7 are respectively fixed on the base plate 1 and the top plate 2 at the top and bottom of the detection channel.
[0023] In practice, two synchronous belts 5 clamp the battery cells that are fed into the detection channel, and at the same time, the synchronous belts 5 drive the battery cells to move forward synchronously. During the forward movement of the battery cells, the detection components 7 at the top and bottom of the detection channel continuously detect the battery cells.
[0024] Further reference Figures 1 to 3 The synchronous belt 5 has a tensioning assembly fixed to the base plate 1 inside.
[0025] In practice, by setting the tensioning component, the timing belt 5 is kept taut at all times, so that the timing belt 5 is always pressed against the outer wall of the battery cell.
[0026] Further reference Figure 3 The tensioning assembly includes two upright plates 11 fixed on the base plate 1. A spring 12 is fixedly connected to the inner surface of the upright plate 11, and the other end of the spring 12 is provided with a roller 13 that abuts against the timing belt 5.
[0027] In practice, when the tensioning assembly is tensioning, the elastic force provided by the spring 12 pushes the roller 13 to press the synchronous belt 5, so that the synchronous belt 5 is tightened and pressed against the outer wall of the battery cell.
[0028] Further reference Figure 2 and Figure 6 A number of shrinkage holes 6 are evenly provided in the middle of the upper surface of the base plate 1 and the middle of the lower surface of the top plate 2. The detection component 7 is installed inside the shrinkage hole 6. The detection component 7 includes a spherical sleeve 71 movably connected inside the shrinkage hole 6. The spherical sleeve 71 has a cylindrical structure. The bottom end of the spherical sleeve 71 is rotatably connected to a metal ball 72 that abuts against the electrodes at both ends of the battery cell through a spherical hole.
[0029] In practical implementation, when the battery cell is being tested inside the detection channel, the electrodes at both ends of the battery cell are simultaneously connected to the detection component 7. The metal ball 72 makes contact with the electrodes, and the battery cell is tested according to the discharge status of the two electrodes. The setting of the metal ball 72 allows the battery cell to move forward without affecting the connection between the metal ball 72 and the battery cell electrodes. That is, continuous feeding and continuous testing can be carried out without interruption. When the metal ball 72 contacts the current battery cell, the battery cell continues to move forward, so that the battery cell contacts the metal ball 72 of the next detection component 7, and the next battery cell enters the detection area.
[0030] Further reference Figure 6 A disc spring 73 is fixedly connected between the inner end of the spherical sleeve 71 and the inner end of the contraction hole 6.
[0031] In practical implementation, the disc spring 73 ensures that the metal ball 72 is always tightly connected to the electrode through its elastic force.
[0032] Furthermore, the spherical sleeve 71, the metal ball 72, and the disc spring 73 are all made of conductive material and are connected to the electrical signals of the detection host.
[0033] In practice, the testing unit detects the battery cell based on the electrical signals from the two poles of the battery cell connected to the spherical sleeve 71, the metal ball 72, and the disc spring 73.
[0034] Testing includes, but is not limited to: charging, resistance measurement, and discharging.
[0035] During charging, the spherical sleeve 71, the metal ball 72, and the disc spring 73 are connected to the charging circuit.
[0036] To measure resistance, the spherical sleeve 71, the metal ball 72, and the disc spring 73 are connected to the resistance measuring circuit.
[0037] Discharge occurs when the spherical sleeve 71, metal ball 72, and disc spring 73 are connected to the discharge circuit.
[0038] It can perform charging, resistance measurement, and discharging independently.
[0039] It can also perform charging, resistance measurement, and discharging simultaneously.
[0040] Along the direction of the battery cell's movement, the spherical sleeve 71, metal ball 72, and disc spring 73 of different detection components 7 are sequentially connected to different detection circuits.
[0041] Furthermore, the synchronous belt 5 is driven by a servo motor and a reducer, and the two synchronous pulleys 4 at the same end are driven by gear meshing.
[0042] In practical implementation, when the synchronous belt 5 is working, it is powered by a servo motor. The servo motor drives the reducer to rotate, and the output end of the reducer drives one of the synchronous pulleys 4 to rotate. The two synchronous pulleys 4 on the same end are driven by two meshing synchronous gears, so that the two synchronous pulleys 4 on the same end rotate synchronously, so that the two synchronous belts 5 rotate synchronously, and so that the battery cells held by the two synchronous belts 5 move inside the detection channel.
