Description

Technical Field

[0001] The invention relates to the field of lithium battery charging detection, and in particular to a charging detection device for lithium battery processing. Background Art

[0002] The charging detection device for lithium battery processing is a device specially used to detect the various performance parameters of mobile phone lithium batteries during the charging process. Usually, the charging detection device is equipped with high-precision sensors to accurately obtain relevant information of the battery. Some are equipped with intelligent analysis software that can quickly generate detailed test reports to help staff better understand the battery status and performance. It plays an important role in quality control in the production process of mobile phone lithium batteries to ensure that the charging performance of lithium batteries meets the requirements.

[0003] The charging detection devices on the market are usually designed as small and lightweight devices for portable use, rather than industrial-grade devices that work continuously for a long time. Therefore, their hardware and software designs may not take into account the needs of continuous charging detection. Lithium battery charging detection devices are usually designed for single charging operations, rather than long-term operations of continuous charging detection of lithium batteries, which leads to reduced efficiency of lithium battery charging detection. First, due to design limitations, such devices can usually only monitor and evaluate the battery during a single charging process, and cannot provide continuous and long-term battery performance data, such as charging rate, charging efficiency, etc. Secondly, such devices usually do not have the ability to work continuously and cannot meet the needs of long-term use or long-term charging processes. In practical applications, such as large-scale charging operations in industrial production, such devices cannot effectively cope with them. In addition, due to the limitations of single charging operations, such devices cannot comprehensively monitor and detect various battery faults. Therefore, there are certain limitations in fault detection.

[0004] The lithium battery charging and testing devices on the market are relatively complicated in their fixing and disassembly methods before testing lithium batteries. The complicated fixing and disassembly methods will increase the complexity and time-consuming of the staff, reduce the efficiency of the test, and the staff will need to spend more time and energy to complete the fixing and disassembly of the lithium battery. At the same time, the complicated fixing and disassembly methods increase the risk of misoperation, especially for staff who are not familiar with the operation. The probability of accidental damage to the lithium battery during the test process increases. At the same time, the fixing method of lithium batteries on the market is usually set to a fixed size, thereby reducing the adaptability of the lithium battery charging and testing device. At the same time, if the lithium battery charging and testing device is not fixed, the lithium battery block will leak during the test, which will cause accidental injury to the staff.

[0005] Therefore, it is necessary to provide a charging detection device for lithium battery processing to solve the above problems. Summary of the invention

[0017] The present invention provides a charging detection device for lithium battery processing. Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

[0019] 2. Through the setting of the positioning component, when the staff holds the lithium battery block and presses it between the two limit blocks, the lithium battery will be squeezed along the inclined surface of the limit block due to its own shape to move toward the positioning cylinder group. At the same time, when the lithium battery moves along the inner wall of the limit block to the top of the lithium battery detection device, the reset spring group will elastically stretch and push the two limit blocks to move toward the lithium battery block, thereby clamping the lithium battery block, thereby achieving the purpose of fixing the lithium battery block, and at the same time simplifying the fixing steps of the lithium battery charging detection device, and reducing the complexity and difficulty of the staff's operation, so that the staff can more easily perform charging detection on the lithium battery, reducing the risk of staff misoperation, and reducing the possibility of damage to the equipment or lithium battery during the fixing process.

[0037] The positioning component includes a limiting slide groove 21, which is opened inside the lithium battery detection device 11, and the limiting slide groove 21 is fixedly connected to the inside of the limiting slide groove 21. The limiting slide groove 21 is fixedly connected to the inside of the positioning cylinder group 23, and the positioning cylinder group 23 is slidably connected to the inside of the columnar slide rod group 24.

The bottom of the limit block 25 is fixedly connected to a fixed rod 27, and the two ends of the fixed rod 27 are symmetrically rotatably connected to pulleys 28. A power-on button 29 is arranged on the top of the lithium battery detection device 11.

[0039] The top of the limit block 25 is set to be inclined, so that the lithium battery block 12 can be easily fixed by contacting the inclined part of the limit block 25. The material of the columnar slide bar group 24 is set to iron, so that the electromagnet group 22 can magnetically attract the columnar slide bar group 24, and the pulley 28 is slidably connected to the bottom of the limit slide groove 21.

[0040] The detection assembly includes a driving device 31, which is fixedly connected to the top of the lithium battery detection device 11. A rotating disk 32 is fixedly connected to the output shaft of the driving device 31. An arc groove 33 is opened inside the rotating disk 32. A first elliptical block 34 and a second elliptical block 35 are fixedly connected to the side of the rotating disk 32 away from the driving device 31.

[0041] The detection component also includes a T-shaped groove positioning block 36, which is fixedly connected to the top of the lithium battery detection device 11. The top of the T-shaped groove positioning block 36 is slidably connected to a T-shaped slide plate 37. The top of the T-shaped slide plate 37 is fixedly connected to a first fixed block 38 and a second fixed block 39. The top of the first fixed block 38 is fixedly connected to a bar push rod 310, and the middle of the bar push rod 310 is rotatably connected to a rotating wheel 311. The end of the bar push rod 310 away from the first fixed block 38 is provided with a strip groove 312. The top of the second fixed block 39 is rotatably connected to a scissor-shaped rotating rod group 313, and the end of the scissor-shaped rotating rod group 313 close to the second fixed block 39 is fixedly connected to a detection block group 314, and an alarm light 315 is provided on the top of the detection block group 314.

[0042] The first elliptical block 34 and the second elliptical block 35 are symmetrically arranged, so that the first elliptical block 34 and the second elliptical block 35 can abut against the scissor-shaped rotating rod set 313 at the same time.

[0043] The rotating wheel 311 is slidably connected to the inside of the rotating disk 32, so that the rotating disk 32 can drive the rotating wheel 311 to move through the arc groove 33, and the strip push rod 310 is slidably connected to the side of the rotating disk 32 away from the driving device 31, so that the strip groove 312 drives the strip push rod 310 to move horizontally.

[0044] A torsion spring is provided between the scissor-shaped rotating rod set 313 and the second fixed block 39 , so that the end of the scissor-shaped rotating rod set 313 away from the second fixed block 39 always contacts the outer wall of the first elliptical block 34 and the second elliptical block 35 .

[0045] There is an electrical connection between the power button 29 and the electromagnet group 22, so that the power button 29 can control the power on and off of the electromagnet group 22, and there is an electrical connection between the power button 29 and the drive device 31 and the power supply used by the equipment, so that the power button 29 and the drive device 31 are powered on synchronously when the power supply of the equipment is powered on.

[0046] Before the lithium battery detection device 11 performs charging detection on the lithium battery block 12, the lithium battery block 12 needs to be fixed. At this time, the staff can first hold the lithium battery block 12 against the two limit blocks 25 and move it toward the lithium battery detection device 11. Then, the two limit blocks 25 are moved toward the positioning cylinder group 23 by the lithium battery block 12. At the same time, the two limit blocks 25 gradually compress the reset spring group 26 toward the positioning cylinder group 23. When the lithium battery block 12 moves to the lower part of the inclined shape at the top of the limit blocks 25, the reset spring group 26 will elastically stretch and push the two limit blocks 25 to move away from the positioning cylinder group 23. At the same time, the limit blocks 25 clamp the lithium battery block 12. Then, after the staff moves the lithium battery block 12 between the two limit blocks 25 to the top of the lithium battery detection device 11, the fixed lithium battery block 12 can be charged and detected.

[0047] When the staff needs to take out the lithium battery block 12, the staff can energize the electromagnet group 22 by pressing the power button 29. The electromagnet group 22 is then energized to magnetize the columnar slide bar group 24, so that the columnar slide bar group 24 slides along the inside of the positioning cylinder group 23, pulling the two limit blocks 25 to move. At the same time, the two limit blocks 25 compress the return spring group 26 toward the positioning cylinder group 23 again, so that the two limit blocks 25 release the clamping of the lithium battery block 12. At this time, the staff can take out the lithium battery block 12, thereby achieving the purpose of facilitating the fixing and removal of the lithium battery block 12.

[0048] Working principle: In the initial state,

[0049] When working, before the lithium battery detection device 11 performs charging detection on the lithium battery block 12, the staff first starts the equipment to use the power supply, and then needs to fix the lithium battery block 12. At this time, the staff can first hold the lithium battery block 12 to resist the two limit blocks 25 and move it toward the direction of the lithium battery detection device 11. Because the top of the limit block 25 is set to an inclined shape, the two limit blocks 25 are then resisted by the lithium battery block 12 to move toward the positioning cylinder group 23. At the same time, the two limit blocks 25 gradually compress the reset spring group 26 in the direction of the positioning cylinder group 23. When the lithium battery block 12 moves to the bottom of the inclined shape at the top of the limit block 25, the reset spring group 26 will elastically stretch and push the two limit blocks 25 to move away from the positioning cylinder group 23. At the same time, the limit blocks 25 clamp the lithium battery block 12. Then the staff moves the lithium battery block 12 between the two limit blocks 25 to the top of the lithium battery detection device 11, and then the fixed lithium battery block 12 can be charged and detected.

[0050] When the staff needs to take out the lithium battery block 12, because there is an electrical connection between the power button 29 and the electromagnet group 22, and the power button 29 and the drive device 31 are both electrically connected to the power supply used by the equipment, the staff can press the power button 29 to energize the electromagnet group 22, and then the electromagnet group 22 is energized to magnetically attract the columnar slide bar group 24. The material of the columnar slide bar group 24 is set to iron, so that the columnar slide bar group 24 slides along the inside of the positioning tube group 23, pulling the two limit blocks 25 fixedly connected to it to move, and at the same time, the two limit blocks 25 compress the reset spring group 26 toward the positioning tube group 23 again, so that the two limit blocks 25 release the clamping of the lithium battery block 12, and the staff can take out the lithium battery block 12 at this time, so as to achieve the purpose of facilitating the fixing and disassembly of the lithium battery block 12.

[0051] Finally, similar to the above movement process, the reset spring group 26 will elastically stretch and push the two limit blocks 25 to move away from the positioning tube group 23, thereby achieving the purpose of resetting the two limit blocks 25, making it easier for the two limit blocks 25 to fix the lithium battery block 12 again, thereby facilitating subsequent charging detection of the lithium battery block 12.

[0052] When the staff has finished fixing the lithium battery block 12, since the driving device 31 is electrically connected to the power supply of the equipment, and the power supply of the equipment is turned on at this time, the driving device 31 drives the rotating disk 32 to rotate through the output shaft. Since the rotating wheel 311 is slidably connected to the inside of the rotating disk 32, the internal rotating wheel 311 is driven to slide through the arc groove 33 during the process of driving the rotating disk 32 to rotate, and the strip push rod 310 is slidably connected to the side of the rotating disk 32 away from the driving device 31. At this time, the strip groove 312 restricts the strip push rod 310 to move in a horizontal trajectory away from the rotating disk 32. Then, the rotating wheel 311 drives the strip push rod 310 to move first in the direction away from the rotating disk 32, and the strip push rod 310 pushes the first fixed block 38 to move, and the first fixed block 38 drives the T-shaped slide plate 37 to slide along the inside of the T-shaped groove positioning block 36, and then the second fixed block 39 drives the scissor-shaped rotating rod group 313 to move toward the lithium battery block 12;

[0053] As the rotating disk 32 rotates, the first elliptical block 34 and the second elliptical block 35 away from the driving device 31 are driven to rotate synchronously, and the first elliptical block 34 and the second elliptical block 35 are arranged in a symmetrical direction, and a torsion spring is arranged between the scissor-shaped rotating rod group 313 and the second fixed block 39. At this time, the end of the scissor-shaped rotating rod group 313 away from the second fixed block 39 is always in conflict with the first elliptical block 34 and the second elliptical block 35, and the rotating disk 32 rotates, the first elliptical block 34 and the second elliptical block 35 are driven to rotate synchronously, so that the scissor-shaped rotating rod group 313 moves toward the lithium battery block 12 due to the first elliptical block 34 and the second elliptical block 35. The block 35 is interfered with, so that the gap of the end of the scissor-shaped rotating rod group 313 close to the second fixed block 39 is continuously reduced, and then the second fixed block 39 drives the scissor-shaped rotating rod group 313 to move toward the lithium battery block 12. At the same time, the gap of the end of the scissor-shaped rotating rod group 313 close to the second fixed block 39 is continuously reduced, so that the scissor-shaped rotating rod group 313 drives the detection block group 314 to interfere with the lithium battery block 12 around the second fixed block 39, so that the detection block group 314 can perform charging detection on the lithium battery block 12. If the lithium battery block 12 fails during the detection process, the alarm light 315 on the top of the detection block group 314 will light up, which serves the purpose of prompting the staff;

[0054] The above-mentioned movement process is opposite. At this time, the driving device 31 continues to drive the rotating disk 32 to rotate. Then, the rotating disk 32 drives the internal rotating wheel 311 to slide through the arc groove 33. Due to the shape characteristics of the arc groove 33, the rotating wheel 311 drives the strip push rod 310 to move in a horizontal trajectory toward the rotating disk 32, and the strip push rod 310 will synchronously pull the first fixed block 38 to move toward the rotating disk 32, and the first fixed block 38 will drive the second fixed block 39 to move toward the rotating disk 32 through the T-shaped slide plate 37. The second fixed block 39 will drive the scissor-shaped rotating rod group 313 to move away from the lithium battery block 12. At the same time, the rotating disk 32 drives the first elliptical block 34 and the second elliptical block 35 to rotate synchronously. At this time, the torsion spring causes the gap between the scissor-shaped rotating rod group 313 and the second fixed block 39 to increase continuously, so that the scissor-shaped rotating rod group 313 drives the detection block group 314 to release the wrapping of the lithium battery block 12, thereby achieving the purpose of continuously performing charging detection on the lithium battery block 12 during the process of the driving device 31 driving the rotating disk 32 to rotate.
