Description

Technical Field

[0001] This utility model relates to the field of waste lithium battery testing technology, and in particular to a waste lithium battery testing device. Background Technology

[0002] Used lithium batteries refer to lithium-ion batteries that have lost their usability. They mainly include two types: power batteries and consumer electronics batteries. Therefore, it is necessary to test used lithium batteries.

[0003] A waste lithium battery testing device, published under application number "CN113504471A", uses two testing pens to contact the positive and negative terminals of the waste lithium battery and uses an ammeter to test the battery's lifespan. However, when testing waste lithium batteries of different sizes, the batteries tend to move around in the circular storage compartment, leading to unstable fixation and affecting the testing process. This increases operational limitations. Furthermore, after testing, workers need to collect the batteries one by one, which consumes a significant amount of time and reduces work efficiency. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing a waste lithium battery testing device, thereby reducing operational limitations and improving work efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This waste lithium battery detection device includes a frame and a first cylinder. The upper inner wall of the frame is fixedly connected to the first cylinder. A recycling mechanism is installed on the lower inner wall of the frame. A disassembly mechanism is installed at the upper end of the recycling mechanism. The output ends of the first cylinder are all fixedly connected to the housing. The housing is fixedly connected to the servo motor through a bracket. The output shaft of the servo motor is connected to the double-ended stud through a reduction gearbox. Both sides of the double-ended stud are rotatably connected to the housing through bearings.

[0006] To further improve the system, the recycling mechanism includes a frame, the lower outer wall of which is slidably connected to a frame, the inner wall of which is fixedly connected to an electric telescopic rod, and the output end of which is fixedly connected to a vertical rod.

[0007] Further improvements include: the upper inner wall of the vertical rod is rotatably connected to the roller via a bearing; the outer wall of the roller is slidably connected to the horizontal plate; the upper end of the horizontal plate is fixedly connected to the housing; and the rear end of the frame is fixedly connected to the output end of the second cylinder.

[0008] Further improvements include a housing, the lower side of which is rotatably connected to the frame via a pivot, the inner wall of which is fixedly connected to the column, the right inner wall of which is slidably connected to the support rod, the inner walls of which are slidably connected to the crossbar on both sides, a spring on the outer wall of which is fixedly connected to the housing and the support rod at both ends, the left side of which is engaged with the lower plate, and the inner wall of which is slidably connected to the lower side of the lower plate.

[0009] Further improvements include: the outer wall of the column is inserted into the lower plate; the inner walls on both sides of the lower plate are rotatably connected to the ends of bolts via bearings; and the outer walls of the bolts are threadedly connected to the upper plate.

[0010] Further improvements include: both outer walls of the double-ended stud are threadedly connected to the vertical block; the upper outer wall and middle outer wall of the vertical block are slidably connected to the housing; the inner side below the vertical block is fixedly connected to the detection pen; and a second cylinder is fixedly connected to the rear outer wall of the frame.

[0011] The beneficial effects of this utility model are as follows: In this utility model, through the cooperation of the disassembly mechanism and the housing, the support rod 202 is moved outward to separate it from the lower side of the lower plate. At this time, the spring contracts. After the support rod is separated from the lower plate, the movement of the support rod stops. Then, the lower plate is moved upward to remove it from the housing. After the lower plate is removed from the housing, the support rod is released, the spring rebounds, and the support rod returns to its original position. Then, a new lower plate and an upper plate are replaced, and the new lower plate is placed back into the housing. When the lower plate moves within the housing, the worker does not need to move the support rod again. The lower plate is located below... The slope of the upper plate contacts the slope of the left end of the support rod, causing the support rod to move to the right. After the lower plate moves to the bottom of the housing, the groove on the right side of the lower plate aligns with the support rod. The support rod then moves into the lower plate through the spring's return and engages with the lower plate, thus limiting the position of the replaced lower plate. By replacing the lower plate and the upper plate in the above manner, the upper and lower plates are replaced according to the size of the waste lithium battery being tested, so that they fit the waste lithium battery more closely, thereby increasing the stability of fixing the waste lithium battery and reducing operational limitations.

[0012] Through the cooperation of the recycling mechanism and the frame, the output end of the electric telescopic pole extends, thereby driving the vertical pole to move upward. The vertical pole drives the roller to move upward, and the roller drives the shell to rotate counterclockwise around the frame through the slide groove. When the shell rotates, it creates an inclination, which in turn causes the lower plate to tilt. When the lower plate tilts, the waste lithium batteries on the lower plate will slide off the lower plate and detach from it. Workers can then collect them using an external box. In this way, all waste lithium batteries are recycled, eliminating the need for workers to remove and recycle them one by one, saving the time spent on recycling and increasing work efficiency.

The model of the second cylinder 12 can be selected according to actual needs to meet the working requirements.

[0023] See attached document Figure 1-5 The recycling mechanism 3 includes a frame 301. The lower outer wall of the frame 301 is slidably connected to the frame 1. The inner wall of the frame 301 is fixedly connected to the electric telescopic rod 302. The model of the electric telescopic rod 302 can meet the actual needs of the work. The output end of the electric telescopic rod 302 is fixedly connected to the vertical rod 303. The electric telescopic rod 302 drives the vertical rod 303 to move. The upper inner wall of the vertical rod 303 is rotatably connected to the roller 304 through the bearing. The roller 304 rotates inside the vertical rod 303. The outer wall of the roller 304 is slidably connected to the horizontal plate 305. The roller 304 drives the horizontal plate 305 to rotate. The upper end of the horizontal plate 305 is fixedly connected to the housing 201. The horizontal plate 305 drives the housing 201 to rotate. The rear end of the frame 301 is fixedly connected to the output end of the second cylinder 12. The second cylinder 12 drives the frame 301 to move.

[0024] See attached document Figure 2-5 The disassembly mechanism 2 includes a housing 201. The lower side of the housing 201 is rotatably connected to the frame 301 via a pivot. The housing 201 rotates on the frame 301. The inner wall of the housing 201 is fixedly connected to the column 205. The right inner wall of the housing 201 is slidably connected to the support rod 202. The support rod 202 slides within the housing 201. Both inner walls of the support rod 202 are slidably connected to the crossbar 203. The support rod 202 slides on the crossbar 203. A spring 204 is provided on the outer wall of the crossbar 203. The elastic coefficient of the spring 204 meets the requirements of the actual work. As needed, the two ends of the spring 204 are fixedly connected to the housing 201 and the support rod 202 respectively. The left side of the support rod 202 is engaged with the lower plate 10. The inner wall of the housing 201 is slidably connected to the lower side of the lower plate 10. The lower plate 10 slides inside the housing 201. The outer wall of the column 205 is inserted into the lower plate 10. The inner walls on both sides of the lower plate 10 are rotatably connected to the ends of the bolts 13 through bearings. The bolts 13 rotate on the lower plate 10. The outer walls of the bolts 13 are threadedly connected to the upper plate 11. The bolts 13 drive the upper plate 11 to move.

[0025] Working principle: When it is necessary to test the waste lithium battery, place the waste lithium battery in the groove of the lower plate 10, and then turn the bolts 13 on both sides to move the upper plate 11 downward until it is pressed against the upper end of the waste lithium battery on the lower plate 10. Then stop turning the bolts 13 on both sides. In this way, the waste lithium battery is fixed between the lower plate 10 and the upper plate 11. Then connect the external power supply of the two first cylinders 4 and start them. The output ends of the two first cylinders 4 extend and drive the box 5 to move. The box 5 drives the two vertical blocks 8 to move, which in turn drives the two test pens. After aligning the detection end of 9 with both ends of the waste lithium battery, the two first cylinders 4 are closed. Then, the external power supply of the servo motor 6 is connected and started. The servo motor 6 drives the double-ended stud 7 to rotate, and the double-ended stud 7 drives the two vertical blocks 8 to move inward, thereby causing the two detection pens 9 to move inward. The detection ends of the two detection pens 9 contact the waste lithium battery to detect it. After the two detection pens 9 contact the waste lithium battery, the servo motor 6 is closed (the left detection pen 9 contacts the positive terminal of the waste lithium battery, while the right detection pen 9 contacts the negative terminal of the waste lithium battery, such as...). Figure 2 When placing used lithium batteries, the positive and negative terminals of each battery must be in the same direction. The data after testing will be transmitted to the back-end computer, and workers can record the data.

[0026] After one waste lithium battery is tested, the servo motor 6 is started and reversed to separate the two testing pens 9 from the waste lithium battery. After the two testing pens 9 are separated from the waste lithium battery, the servo motor 6 is turned off. Then the external power supply of the second cylinder 12 is connected and started. The second cylinder 12 drives the frame 301 to move, which in turn causes the lower plate 10 and the upper plate 11 to move the waste lithium battery. After the two sides of the next waste lithium battery move to between the two testing pens 9, the cylinder 12 is turned off. Then the next waste lithium battery can be tested in the same way. The remaining waste lithium batteries can be tested in the same way.

[0027] After the waste lithium battery is tested, the servo motor 6 first moves the two detection pens 9 outwards to their reset position. Once the two detection pens 9 have moved to their reset position, the servo motor 6 is turned off. Then, the output ends of the two first cylinders 4 are retracted, causing the housing 5 to move upwards, which in turn moves the two detection pens 9 upwards to their reset position. Once the two detection pens 9 have moved to their reset position, the two first cylinders 4 are turned off.

[0028] Reverse the bolts 13 on both sides of the upper plate 11 to separate the first plate 11 from the waste lithium battery, thus removing the fixation of the waste lithium battery. Then, start the external power supply of the electric telescopic rod 302. The output end of the electric telescopic rod 302 extends, thereby driving the vertical rod 303 to move upward. The vertical rod 303 drives the roller 304 to move upward. The roller 304 drives the housing 201 to rotate counterclockwise around the frame 301 through the sliding groove (e.g., Figure 2 The maximum rotation angle of the housing 201 is 35 degrees. When the housing 201 rotates, it creates an inclination, which in turn causes the lower plate 10 to tilt. When the lower plate 10 tilts, the waste lithium batteries on the lower plate 10 will slide off the lower plate 10 and detach from it. Workers can then collect them using an external container, eliminating the need for workers to remove and recycle the waste lithium batteries one by one. After all the waste lithium batteries have been recycled, the output end of the electric telescopic rod 302 retracts according to the above method, thereby resetting the lower plate 10. After the lower plate 10 is reset, the electric telescopic rod 302 is turned off. The detection of waste lithium batteries is completed in the above manner.

[0029] When inspecting used lithium batteries of different sizes, the lower plate 10 and upper plate 11 with different groove sizes can be replaced. The support rod 202 is moved outwards to separate it from the lower side of the lower plate 10. At this time, the spring 204 contracts. After the support rod 202 separates from the lower plate 10, the movement of the support rod 202 stops. Then, the lower plate 11 is moved upwards to remove it from the housing 201. After the lower plate 11 is removed from the housing 201, the support rod 202 is released, and the spring 204 rebounds, thus resetting the support rod 202. Then, a new lower plate is replaced. 10 and upper plate 11 (the grooves in the lower plate 10 and upper plate 11 are similar in size to the outer wall of the waste lithium battery to be inspected). Place the new lower plate 10 back into the housing 201. When the lower plate 10 moves within the housing 201, the worker does not need to move the support rod 202 again. The slope below the lower plate 10 contacts the slope at the left end of the support rod 202, which will cause the support rod 202 to move to the right (the outer wall of the support rod 202 is relatively smooth, which can avoid damaging the lower plate 10 when the support rod 202 contacts the lower plate 10).

[0030] After the lower plate 10 moves to the bottom of the housing 201, the groove on the right side of the lower plate 10 aligns with the support rod 202. The support rod 202 then moves into the lower plate 10 through the spring 204 and engages with the lower plate 10, thereby limiting the replacement of the lower plate 10. The replacement of the lower plate 10 and the upper plate 11 is completed in the above manner. The upper plate 11 and the lower plate 10 are replaced according to the size of the waste lithium battery to make them fit the waste lithium battery better, thereby increasing the stability of fixing the waste lithium battery.
