In existing technology, battery cell testing equipment can only test a single parameter such as voltage or internal resistance, resulting in limited functionality and practicality. Utility Model Content
[0003] The purpose of this invention is to provide a battery cell testing device, which aims to solve the technical problems of the limited functionality and low practicality of existing battery cell testing devices.
[0004] This application provides a battery cell testing device, which includes a workbench, a fixture, a barcode scanner, a testing device, and a conveying device. The fixture is used to fix the battery cell, the barcode scanner is used to scan the QR code on the battery cell, the testing device is used to test the battery cell, and the conveying device has a first station, a second station, a third station, and a fourth station arranged sequentially. The conveying device is used to transport the fixture horizontally to the first station, the second station, the third station, and the fourth station. The barcode scanner, the testing device, and the conveying device are all located on the workbench. One of the first station and the fourth station is a loading station, and the other is a unloading station. One of the second station and the third station is equipped with a barcode scanner, and the other is equipped with a testing device.
[0005] The beneficial effects of the battery cell testing equipment provided by this utility model are as follows: It should be noted that the first station can be either a loading station or a unloading station. Similarly, the fourth station can be either a loading station or a unloading station; either one is sufficient as long as it is a loading station and the other is an unloading station. The barcode scanning device can be configured at the second station or the third station. Similarly, the testing device can be configured at the third station or the second station; either one is acceptable as long as they are not configured at the same station.
[0006] For example, in some technical solutions, the first, second, third, and fourth stations are respectively the loading station, the barcode scanning device, the testing device, and the unloading station. In other technical solutions, the first, second, third, and fourth stations are respectively the unloading station, the barcode scanning device, the testing device, and the loading station.

[0007] For ease of description and understanding, the first, second, third, and fourth workstations are referred to as the loading station, barcode scanning device, testing device, and unloading station, respectively. During operation, the battery cell to be tested is placed in the fixture located at the first workstation. The conveyor transports the fixture carrying the battery cell to the second workstation, where the barcode scanning device scans the battery cell. The conveyor then transports the scanned battery cell to the third workstation, where the testing device checks its voltage or internal resistance. After testing, the conveyor transports the fixture to the fourth workstation, where the battery cell is finally removed from the fixture manually or by an automated mechanism (such as a robotic arm).
[0008] In this application, a barcode scanning device is installed to scan the barcodes of the battery cells to be tested, binding the test values and barcode values and uploading them to the cloud. This facilitates later traceability, and if product problems arise later, repairs can be carried out. Thus, the multi-functionality of the battery cell testing equipment is realized, greatly improving its practicality.

[0037] Please refer to Figures 1 to 5 The following describes a battery cell testing device 100 according to an embodiment of the present utility model.
[0038] Please refer to Figure 2 and Figure 4 For ease of description and explanation, we define the front-back direction, the left-right direction, and the up-down direction.
[0039] Please refer to Figure 1 and Figure 2 This application provides a battery cell testing device 100, which includes a workbench 20, a fixture 30, a barcode scanner (not shown), a testing device (not shown), and a conveying device 10. The fixture 30 is used to fix the battery cell 40, the barcode scanner is used to scan the QR code on the battery cell 40, the testing device is used to test the battery cell 40, and the conveying device 10 has a first station 11, a second station 12, a third station 13, and a fourth station 14 arranged sequentially. The conveying device 10 is used to convey the fixture 30 horizontally to the first station 11, the second station 12, the third station 13, and the fourth station 14. The barcode scanner, the testing device, and the conveying device 10 are all located on the workbench 20. One of the first station 11 and the fourth station 14 is a loading station, and the other is a unloading station. One of the second station 12 and the third station 13 is equipped with a barcode scanner, and the other is equipped with a testing device. Specifically, the first station 11, the second station 12, the third station 13 and the fourth station 14 extend in the front-back direction.
[0040] It should be noted that the first station 11 can be either a loading station or a unloading station. Similarly, the fourth station 14 can be either a loading station or a unloading station, as long as one of them is a loading station and the other is an unloading station. The barcode scanning device can be configured at the second station 12 or the third station 13. Similarly, the detection device can be configured at the third station 13 or the second station 12, as long as they are not configured at the same station.
[0041] For example, in some embodiments, the first station 11, the second station 12, the third station 13, and the fourth station 14 are respectively a loading station, a barcode scanning device, a detection device, and a unloading station. As another example, in some embodiments, the first station 11, the second station 12, the third station 13, and the fourth station 14 are respectively a unloading station, a barcode scanning device, a detection device, and a loading station. Therefore, the battery cell 40 can be scanned first and then detected, or detected first and then scanned.
[0042] For ease of description and understanding, the first station 11, the second station 12, the third station 13, and the fourth station 14 are referred to as the loading station, the barcode scanning device, the testing device, and the unloading station, respectively. During operation, the battery cell 40 to be tested is placed in the fixture 30 located at the first station 11. The conveying device 10 transports the fixture 30 carrying the battery cell 40 to the second station 12, where the barcode scanning device scans the battery cell 40. Subsequently, the conveying device 10 transports the scanned battery cell 40 to the third station 13, where the testing device performs voltage or internal resistance testing on the battery cell 40. After testing, the conveying device 10 transports the fixture 30 to the fourth station 14, where the battery cell 40 is finally removed from the fixture 30 manually or by an automated mechanism (such as a robotic arm).
[0043] In this application, by setting up a barcode scanning device, the barcode of the battery cell 40 to be tested can be scanned to bind the test value and the barcode value and upload them to the cloud, which facilitates later traceability. If the product has problems later, it can be returned for repair. In this way, the multi-functionality of the battery cell testing equipment 100 is realized, which greatly improves the practicality of the battery cell testing equipment 100.
[0044] In another embodiment of this application, please refer to Figure 3 The first station 11 is provided with a first cell sensor 111, a first fixture block 112 and a first drive unit 113. The first cell sensor 111 is installed on the worktable 20 and is used to sense the cell 40. The first drive unit 113 is installed on the worktable 20 and is drivenly connected to the first fixture block 112 so that the first fixture block 112 moves in the up and down direction. The first fixture block 112 is located between the first station 11 and the second station 12.
[0045] Specifically, in this embodiment, the first station 11 is a material loading station. The first cell sensor 111 is located on the side of the first station 11 away from the second station 12, that is, on the rear side of the first station 11. The first cell sensor 111 can be a reflective photoelectric sensor or a laser sensor, which is not limited here. The first drive unit 113 and the first fixture stop 112 are both located between the first station 11 and the second station 12, that is, on the front side of the first station 11. The first drive unit 113 can be a linear motor module, a cylinder, or a hydraulic rod, as long as it can adjust the position of the first fixture stop 112 in the vertical direction, which is not limited here.
[0046] Before placing the battery cell 40 to be tested, the first drive unit 113 drives the first fixture stop 112 to move it upward. The first fixture stop 112 is used to block the fixture 30 located at the first station 11 to facilitate manual or automated feeding. After the battery cell 40 to be tested is assembled onto the fixture 30, the first battery cell sensor 111 senses the battery cell 40 to be tested. At this time, the first drive unit 113 drives the first fixture stop 112 to lower it, so that the fixture 30 can be transported to the second station 12 by the conveying device 10.
[0047] In this embodiment, the first driving component 113 is a cylinder. Of course, in some other embodiments, the first driving component 113 may be a linear motor module or a hydraulic rod, etc., which is not limited here.
[0048] In another embodiment of this application, please refer to Figure 4 and Figure 5 The second station 12 is provided with a second drive component 121, a third drive component 122 and two first clamping components 123. The second drive component 121 and the third drive component 122 are both installed on the worktable 20. The second drive component 121 and the third drive component 122 are respectively driven connected to the two first clamping components 123. The two first clamping components 123 are used to jointly clamp the fixture 30.
[0049] Specifically, of the two first clamping assemblies 123, one first clamping assembly 123 is located on the side of the second station 12 near the first station 11, and the other first clamping assembly 123 is located on the side of the second station 12 near the third station 13. In this application, the second drive member 121 is drivenly connected to the first clamping assembly 123 near the first station 11, and the third drive member 122 is drivenly connected to the first clamping assembly 123 near the third station 13. During operation, the third drive member 122 drives the first clamping assembly 123 to rise, and the first clamping assembly 123 is used to block the fixture 30 and keep the fixture 30 on the second station 12. When the fixture 30 abuts against the first clamping assembly 123 near the third station 13, the second drive member 121 drives the other first clamping assembly 123 to move closer to the fixture 30. Finally, the two first clamping assemblies 123 together clamp the fixture 30. This configuration improves the stability of the fixture 30, making it easier for the scanning device to scan the battery cell 40 or for the testing device to test the battery cell 40, thus improving the accuracy of the test results.
[0050] In another embodiment of this application, please refer to Figure 5 The first clamping assembly 123 includes a first mounting base 1231 and a first fixture clamping block 1232. The first mounting base 1231 is mounted on the worktable 20, and the first fixture clamping block 1232 is hinged to the first mounting base 1231. The telescopic end of the second driving member 121 is hinged to the first fixture clamping block 1232 of one of the first clamping assemblies 123, and the fixed end of the second driving member 121 is hinged to the worktable 20. The telescopic end of the third driving member 122 is hinged to the first fixture clamping block 1232 of the other first clamping assembly 123, and the fixed end of the third driving member 122 is hinged to the worktable 20.
[0051] Specifically, in this embodiment, both the second driving member 121 and the third driving member 122 are cylinders, and the telescopic ends of both the second driving member 121 and the third driving member 122 extend and retract in the front-back direction. The telescopic end of the third driving member 122 is drivenly connected to one end of one of the first fixture clamping blocks 1232. The third driving member 122 drives one end of the first fixture clamping block 1232. Since the first fixture clamping block 1232 is hinged to the corresponding first mounting base 1231, the other end of the first fixture clamping block 1232 rises or falls, thereby limiting or releasing the fixture 30 located on the second work station 12. The telescopic end of the second driving member 121 is driven to one end of another first fixture clamping block 1232. The second driving member 121 drives one end of the first fixture clamping block 1232. Since the first fixture clamping block 1232 is hinged to the corresponding first mounting base 1231, the other end of the first fixture clamping block 1232 rises and approaches the fixture 30 located on the second station 12, or the other end of the first fixture clamping block 1232 falls and moves away from the fixture 30 located on the second station 12, thereby achieving the purpose of clamping or releasing the fixture 30.
[0052] By configuring the first fixture clamping block 1232 to be hinged to the first mounting base 1231, the first fixture clamping block 1232 can move in both the vertical and horizontal directions under the drive of the second drive member 121 or the third drive member 122, which greatly improves flexibility and practicality, reduces costs, and reduces assembly difficulty.
[0053] In another embodiment of this application, please refer to Figure 5 The width of the first fixture clamping block 1232, which is closer to the first fixture stop 112, is greater than the width of the first fixture stop 112. The first fixture clamping block 1232 has a first through slot 1233 for the first fixture stop 112 to pass through. Specifically, in this embodiment, the width refers to the length in the left-right direction. The two first fixture clamping blocks 1232 are used to jointly clamp the fixture 30; therefore, to improve the clamping effect on the fixture 30, the width of the first fixture clamping block 1232 is made larger. The first through slot 1233 ensures that the first fixture clamping block 1232 will not interfere with the first fixture stop 112 during rotation, which helps to improve the compactness of the battery cell testing equipment 100, reduce the volume of the battery cell testing equipment 100, and thus reduce the space occupancy rate.
[0054] In another embodiment of this application, please refer to Figure 4The second station 12 is also equipped with a first feeding support plate 124 and a first lifting drive component 125. The first lifting drive component 125 is mounted on the worktable 20 and is drivenly connected to the first feeding support plate 124 to move the first feeding support plate 124 in the vertical direction. The first feeding support plate 124 is used to lift the fixture 30 so that the fixture 30 is detached from the conveying device 10. When a testing device is configured on the second station 12, the first lifting drive component 125 and the first feeding support plate 124 can improve the testing accuracy of the testing device.
[0055] In another embodiment of this application, please refer to Figure 4 and Figure 5 The second station 12 is also equipped with a second feeding support plate 126 and a second lifting drive component 127. The second lifting drive component 127 is mounted on the worktable 20 and is drivenly connected to the second feeding support plate 126 to move the second feeding support plate 126 in the vertical direction. The second feeding support plate 126 is located below the first feeding support plate 124. The first feeding support plate 124 has a first clearance groove 1241 that penetrates the upper and lower surfaces of the first feeding support plate 124. It is understood that some battery cells 40 need to be tested from the bottom. The second feeding support plate 126 is used to install the test structure to facilitate testing of the battery cell 40 from the bottom.
[0056] In another embodiment of this application, please refer to Figure 2 The fourth station 14 is equipped with a second cell sensor 141, a second fixture stop 142, and a fourth drive unit. The second cell sensor 141 is mounted on the worktable 20 and is used to sense the cell 40. The fourth drive unit is mounted on the worktable 20 and is drivenly connected to the second fixture stop 142, so that the second fixture stop 142 moves vertically. The second fixture stop 142 is located between the third station 13 and the fourth station 14. Specifically, the second cell sensor 141 is located on the side of the fourth station 14 away from the third station 13, that is, on the front side of the fourth station 14. The fourth drive unit and the second fixture stop 142 are both located between the third station 13 and the fourth station 14, that is, on the rear side of the fourth station 14. This arrangement allows the fourth station 14 to also serve as a loading station. Users can switch between the loading and unloading stations at any time according to actual needs, greatly improving flexibility and practicality.
[0057] It is understandable that the second cell sensor 141 can be a reflective photoelectric sensor or a laser sensor. The fourth driving component can be a linear motor module, a cylinder, or a hydraulic rod, as long as it can adjust the position of the second fixture stop 142 in the vertical direction, and is not limited here.
[0058] In another embodiment of this application, the conveying device 10 is a conveyor belt structure.
[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
