Abstract
Description
Technical Field
[0001] This application relates to the field of lithium battery testing equipment technology, and in particular to a tray for lithium battery testing. Background Technology
[0002] Lithium battery winding concentricity refers to the symmetry and consistency of the various parts of the cell (such as the positive electrode, negative electrode, and separator) as they rotate around the central axis during the winding process. The quality of concentricity directly affects the performance and lifespan of the battery.
[0003] Currently, in the process of detecting the concentricity of battery winding, workers need to place the battery on a tray, and then place the tray in an X-ray semiconductor detector to detect the concentricity of the lithium battery winding. During the detection, the lithium battery usually needs to be rotated manually to ensure that the lithium battery is irradiated from multiple angles, thereby improving the detection accuracy of the concentricity of the lithium battery winding.
[0004] However, during the rotation of lithium batteries, it is necessary to stop the machine and frequently open the cabinet door of the X-ray semiconductor detector, and workers need to manually adjust the detection angle of the batteries, resulting in low detection efficiency and significant shortcomings. Utility Model Content
[0005] To address the cumbersome process of testing the concentricity of lithium battery windings, this application provides a tray for testing lithium batteries.
[0006] The lithium battery testing tray provided in this application adopts the following technical solution:
[0007] A lithium battery testing tray includes a tray plate with several pool plates arrayed on the tray plate. An active frame and a support frame are provided on the pool plates. An active roller is rotatably mounted on the active frame, and a support roller is rotatably mounted on the support frame. A battery is mounted between the active roller and the support roller. A drive assembly for driving the active roller to rotate is provided on the tray plate, and a clamping member is provided on the pool plate for clamping both ends of the battery.
[0008] By adopting the above technical solution, after the worker places the battery between the active roller and the support roller on the tray, the two ends of the battery are clamped by the clamping device. Then the tray is placed in the X-ray semiconductor detector. During the inspection of the battery in the X-ray semiconductor detector, the drive component drives the active roller to rotate. The active roller drives the battery to rotate along with it through friction, thereby inspecting the battery from different angles. In this process, no manual intervention is required, which helps to improve the inspection efficiency and the accuracy of the inspection results.
[0009] Optionally, the support roller is hollow inside and open at one end. The clamping member includes a stop bar arranged on the support frame and located at both ends of the axis of the support roller. The stop bar is used to abut the end of the battery. A clamping rod is slidably arranged on the support frame. One end of the clamping rod slides into the interior of the support roller. One of the stop bars is arranged on the clamping rod. A tension spring is provided between the stop bar on the clamping rod and the support frame.
[0010] By adopting the above technical solution, the worker pulls the stop bar connected to the clamping rod, and the tension spring is stretched. After the battery is placed between the drive roller and the support roller, the worker releases the stop bar, the tension spring returns to its original deformation, and the battery is clamped by the two stop bars. This reduces the possibility of the battery coming off during the transfer with the pallet, and at the same time facilitates the drive roller to drive the battery to rotate at different angles through friction.
[0011] Optionally, the baffle bar is provided with a baffle post, and a ball bearing is rotatably disposed on the baffle post, the ball bearing being used to abut against the end of the battery.
[0012] By adopting the above technical solution, when the battery rotates with the active roller, the ball bearings and the end of the battery roll together, thereby reducing the resistance generated during the battery rotation process and facilitating battery rotation.
[0013] Optionally, the drive assembly includes a drive roller rotatably mounted on the tray plate, the drive roller abutting against and rolling with the drive roller, the tray plate having a roller groove for avoiding the drive roller, and the tray plate having a rotating component for driving the drive roller to rotate.
[0014] By adopting the above technical solution, the rotating component drives the transmission roller to rotate, and the transmission roller drives the active roller to rotate through friction, thereby causing the active roller to drive the battery to rotate through friction.
[0015] Optionally, the rotating component includes a transmission wheel coaxially mounted on the transmission roller, a transmission belt wound around the transmission wheels on multiple transmission rollers in the same row, tension wheels rotatably mounted on both sides of the transmission wheel, the tension wheels abutting against the transmission belt, drive wheels rotatably mounted on both ends of the transmission belt located in the same row of transmission wheels, a shaft passing through multiple drive wheels in the same column, a drive motor electrically connected to the control system being mounted on one of the tray plates, and one of the shafts coaxially mounted on the output shaft of the drive motor.
[0016] By adopting the above technical solution, the control system starts the drive motor, the output shaft of the drive motor drives the shaft to rotate, the shaft drives multiple drive wheels on it to rotate synchronously, the drive wheels drive the transmission wheels to rotate through the transmission belt, and the transmission wheels drive the transmission rollers to rotate synchronously, thereby achieving the effect of synchronous rotation of several batteries on the tray, which is beneficial to improving the efficiency of battery detection.
[0017] Optionally, both the drive roller and the transmission roller are fitted with friction sleeves.
[0018] By adopting the above technical solution, the power transmission between the active roller and the drive roller is improved, as is the power transmission between the active roller and the battery, making it easier for the active roller to drive the battery to rotate.
[0019] Optionally, handles are provided on opposite sides of the tray.
[0020] By adopting the above technical solution, it is convenient for workers to transfer pallets and batteries on the pallets.
[0021] Optionally, a protective shell is provided on the bottom of the pallet, and the drive motor and the transmission belt are both located inside the protective shell.
[0022] By adopting the above technical solution, the possibility of damage to the components at the bottom of the pallet is reduced.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. After the worker places the battery between the active roller and the support roller on the tray, the two ends of the battery are clamped by the clamping device. Then the tray is placed in the X-ray semiconductor detector. During the inspection of the battery in the X-ray semiconductor detector, the drive component drives the active roller to rotate. The active roller drives the battery to rotate with it through friction, thereby inspecting the battery from different angles. In this process, no manual intervention is required, which helps to improve the inspection efficiency and the accuracy of the inspection results.
[0025] 2. The worker pulls the stop bar connected to the clamping rod, and the tension spring is stretched. After the battery is placed between the drive roller and the support roller, the worker releases the stop bar, and the tension spring returns to its original deformation. The battery is clamped by the two stop bars, thereby reducing the possibility of the battery coming off during the transfer with the pallet. At the same time, it makes it easier for the drive roller to drive the battery to rotate at different angles through friction.

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.
[0032] This application discloses a tray for testing lithium batteries.
[0033] Reference Figure 1 A lithium battery testing tray includes a tray plate 2, with handles 13 bolted to both horizontally opposite sides of the tray plate 2. Several tray plates 3 are arrayed on the tray plate 2, and an active frame 4 and a support frame 5 are welded to the tray plates 3. A horizontally oriented active roller 6 is rotatably connected to the active frame 4, and a horizontally oriented support roller 7 is rotatably connected to the support frame 5. The outer circumferential wall of the support roller 7 is smooth. The battery 1 is mounted between the active roller 6 and the support roller 7.
[0034] Reference Figure 1 , Figure 2 and Figure 3 The pallet 2 is equipped with a drive assembly 8 that drives the active roller 6 to rotate, and the pallet 3 is equipped with a clamping member 9, which is used to clamp the two ends of the battery 1.
[0035] Reference Figure 1 , Figure 2 and Figure 3 The support roller 7 is hollow inside and open at one end. The clamping member 9 includes a stop bar 91 arranged on the support frame 5 and located at both ends of the axis of the support roller 7. A stop post 10 is welded on the stop bar 91. A ball bearing 11 is rolled on the stop post 10 and is used to abut the end of the battery 1.
[0036] Reference Figure 1 , Figure 2 and Figure 3 A clamping rod 92 is horizontally slidably connected to the support frame 5. One end of the clamping rod 92 slides into the interior of the support roller 7. One of the baffles 91 is welded to the clamping rod 92. A tension spring 93 is arranged between the baffle 91 on the clamping rod 92 and the support frame 5.
[0037] The worker pulls the stop bar 91 with the clamping rod 92. During this process, the tension spring 93 is stretched and deformed. Then the worker places the battery 1 between the support roller 7 and the drive roller 6, and then releases the stop bar 91.
[0038] The tension spring 93 recovers its deformation and drives the baffle 91 to slide. The balls 11 on the baffles 91 on both sides of the battery 1 abut against the end of the battery 1. Repeat the operation to place several batteries 1, and then place the tray 2 in the X-ray semiconductor detector.
[0039] Reference Figure 1 , Figure 2 and Figure 3 The drive assembly 8 includes a drive roller 81 rotatably connected to the tray plate 3. Both the drive roller 6 and the drive roller 81 are fitted with friction sleeves 12. The friction coefficient of the outer circumferential wall of the friction sleeve 12 is relatively large. The friction sleeve 12 on the drive roller 81 abuts and rolls with the friction sleeve 12 on the drive roller 6. The tray plate 3 is vertically provided with a roller groove 82 for avoiding the drive roller 81. The tray plate 3 is provided with a rotating component 83 for driving the drive roller 81 to rotate.
[0040] Reference Figure 1 , Figure 2 and Figure 3 The rotating component 83 includes a transmission wheel 831 coaxially welded to the transmission roller 81. A transmission belt 832 is wound around the transmission wheels 831 on the support plate 2 and on multiple transmission rollers 81 in the same row. Tensioning wheels 833 are rotatably connected to both sides of the transmission wheel 831. The tensioning wheels 833 are used to abut against the transmission belt 832. Drive wheels 834 are rotatably arranged on both ends of the transmission belt 832 and on the same row of transmission wheels 831.
[0041] Reference Figure 1 , Figure 2 and Figure 3 A shaft 835 is connected to multiple drive wheels 834 located in the same row on the pallet 2. A drive motor 836 electrically connected to the control system is bolted to one of the pallet 3. One shaft 835 is coaxially bolted to the output shaft of the drive motor 836. A protective shell 14 is bolted to the bottom of the pallet 2. The drive motor 836 and the transmission belt 832 are both located inside the protective shell 14.
[0042] After the X-ray semiconductor detector completes the inspection of the battery 1 at the same irradiation angle on the tray 2, the control system starts the drive motor 836. The output shaft of the drive motor 836 drives the shaft 835 to rotate. The shaft 835 drives the transmission belt 832 to rotate through the drive wheel 834. At the same time, under the tensioning action of the tension wheel 833, the transmission belt 832 drives the transmission wheel 831 to rotate. The transmission wheel 831 drives the transmission roller 81 to rotate synchronously.
[0043] The transmission roller 81 drives the friction sleeve 12 on the drive roller 6 and the drive roller 6 to rotate through friction. The friction sleeve 12 on the drive roller 6 drives the battery 1 to rotate through friction. During the rotation of the battery 1, the ball 11 always abuts against the end of the battery 1 and rolls until the battery 1 rotates through a certain angle.
[0044] The control system stops the drive motor 836, and then the X-ray semiconductor detector detects the battery 1 at this angle. The operation is repeated until all angles of the battery 1 are detected, thereby improving the accuracy of the detection of the concentricity of the winding of the battery 1.
[0045] The implementation principle of a lithium battery testing tray according to an embodiment of this application is as follows: a worker pulls the stop bar 91 with clamping rod 92. During this process, the tension spring 93 is stretched and deformed. Then the worker places the battery 1 between the support roller 7 and the drive roller 6, and then releases the stop bar 91.
[0046] The tension spring 93 recovers its deformation and drives the baffle 91 to slide. The balls 11 on the baffles 91 on both sides of the battery 1 abut against the end of the battery 1. Repeat the operation to place several batteries 1, and then place the tray 2 in the X-ray semiconductor detector.
[0047] After the X-ray semiconductor detector completes the inspection of the battery 1 at the same irradiation angle on the tray 2, the control system starts the drive motor 836. The output shaft of the drive motor 836 drives the shaft 835 to rotate. The shaft 835 drives the transmission belt 832 to rotate through the drive wheel 834. At the same time, under the tensioning action of the tension wheel 833, the transmission belt 832 drives the transmission wheel 831 to rotate. The transmission wheel 831 drives the transmission roller 81 to rotate synchronously.
[0048] The transmission roller 81 drives the friction sleeve 12 on the drive roller 6 and the drive roller 6 to rotate through friction. The friction sleeve 12 on the drive roller 6 drives the battery 1 to rotate through friction. During the rotation of the battery 1, the ball 11 always abuts against the end of the battery 1 and rolls until the battery 1 rotates through a certain angle.
[0049] The control system stops the drive motor 836, and then the X-ray semiconductor detector detects the battery 1 at this angle. The operation is repeated until all angles of the battery 1 are detected, thereby improving the accuracy of the detection of the concentricity of the winding of the battery 1.
[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
