[0002] As a carrier of new energy, energy storage batteries are widely used in fields such as household appliances, automobiles, aviation, and ships. The use of batteries is inseparable from the battery management system (BMS). The main functions of BMS are to monitor the operating conditions of the battery pack, such as monitoring the voltage of each single cell of the battery core, multi-point temperature monitoring, total voltage / total current monitoring, etc. As BMS undertakes the monitoring function of the entire system operation, therefore, during the production process, it is very necessary to test its stable operation and functional testing. It can only be put into use after passing the test. During the production process of energy storage products, traditional manual or semi-automatic testing methods take up too much production time, thus reducing production efficiency; in addition, large errors are prone to occur during the manual testing process, which also increases the risk of errors in the test results. Therefore, an energy storage BMS automatic testing device is proposed. Content of the Utility Model

[0027] The following further illustrates the technical solutions of the present utility model with reference to the accompanying drawings and through specific implementation manners.
[0028] Referring to Figures 1 to 4 , an embodiment of the present utility model provides an energy storage BMS automatic testing device, including a support frame 10, a mounting bracket 40, a driving mechanism 50, a positioning assembly 20, and a testing assembly 30. A conveyor belt 11 for carrying the battery management system is provided on the support frame 10, and a driving motor 70 for driving the conveyor belt 11 is provided on one side of the support frame 10. A testing station is provided on the conveyor belt 11, and the positioning assembly 20 can position and fix the energy storage BMS conveyed by the conveyor belt 11 at the testing station. Optionally, in order to prevent the self-weight of the energy storage BMS from causing collapse or deformation of the conveyor belt 11, a support plate (not shown in the figure) is provided on the bottom surface of the conveyor belt 11.
[0029] The mounting bracket 40 includes a first support column 41, a support plate 42, a second support column 43 and a first connecting plate 44. Specifically, the first support column 41 is disposed on the support frame 10 and is located on both sides of the conveyor belt 11. The support plate 42 is disposed at one end of the first support column 41 away from the support frame 10. In order to increase the stability of the support plate 42, the number of the first support columns 41 is four, and they are evenly distributed on both sides of the conveyor belt 11. The second support column 43 is disposed on the support plate 42, and the first connecting plate 44 is disposed at one end of the second support column 43 away from the support plate 42.
[0030] The driving mechanism 50 includes a first sliding rod 51, a second connecting plate 52, a mounting plate 53 and a first driving cylinder 54. Specifically, a first through hole is provided on the support plate 42, and the first sliding rod 51 slides on the first through hole. The second connecting plate 52 is disposed at one end of the first sliding rod 51 away from the conveyor belt 11, the mounting plate 53 is disposed at one end of the first sliding rod 51 close to the conveyor belt 11, the fixed end of the first driving cylinder 54 is fixed to the lower end surface of the first connecting plate 44, and the second connecting plate 52 is disposed on the driving end of the first driving cylinder 54.
[0031] The testing assembly 30 includes a testing circuit board 31 disposed on one side of the mounting plate 53 close to the conveyor belt 11 and testing probes 32 disposed on the testing circuit board 31. When the first driving cylinder 54 drives the second connecting plate 52 to move up and down, it can drive the first sliding rod 51 and the mounting plate 53 to move up and down, thereby driving the testing assembly 30 to move up and down.
[0032] The driving mechanism 50 further includes a second sliding rod 55, a limiting ring 56, a spring 57, a third connecting plate 58 and a fourth connecting plate 59 connected. Specifically, a second through hole is further provided on the support plate 42, the second sliding rod 55 slides on the second through hole, the limiting ring 56 is disposed at one end of the second sliding rod 55 away from the conveyor belt 11, one end of the spring 57 is connected to the limiting ring 56, the other end is connected to the third connecting plate 58, the third connecting plate 58 is connected to the second connecting plate 52 through the fourth connecting plate 59, and the driving end of the first driving cylinder 54 is disposed on the fourth connecting plate 59, that is, the first driving cylinder 54 can drive the second connecting plate 52, the third connecting plate 58 and the fourth connecting plate 59 to rise and fall simultaneously.
[0033] The positioning assembly 20 includes a positioning plate 21 disposed at one end of the second sliding rod 55 close to the conveyor belt 11, and the positioning plate 21 is in a T shape. When the first driving cylinder 54 drives the third connecting plate 58 to move up and down, it can drive the spring 57, the limiting ring 56 and the second sliding rod 55 to move up and down, thereby driving the positioning plate 21 to move up and down.
[0034] On both sides of the conveyor belt 11, there are baffles 12 to prevent the energy storage BMS from moving outside the conveyor belt 11. Inside the baffles 12, there are limit blocks 13 corresponding to the mounting plate 53. The diameter of the limit ring 56 is larger than the diameter of the second through hole. When the limit ring 56 restricts the second sliding from continuing to descend, the positioning plate 21 reaches the lowest descending position; when the first driving cylinder 54 continues to drive the second connecting plate 52, the third connecting plate 58, and the fourth connecting plate 59 to descend, the spring 57 is compressed and the first sliding rod 51 continues to descend; when the mounting plate 53 restricts the first sliding from continuing to descend, the test assembly 30 reaches the lowest descending position. It should be noted that when the positioning plate 21 reaches the lowest descending position, the positioning plate 21 blocks the energy storage BMS from continuing to move along with the conveyor belt 11; when the test assembly 30 reaches the lowest descending position, the test probe 32 contacts the test point on the battery management system.
[0035] On both sides of the support frame 10, there are second driving cylinders 60, and the second driving cylinders 60 are located outside the baffles 12. The telescopic rods of the second driving cylinders 60 pass through the baffles 12 and point to the inside of the baffles 12. The positioning assembly 20 further includes positioning clamping plates 22 arranged on the telescopic ends of the second driving cylinders 60 to clamp the energy storage BMS blocked by the positioning plate 21 and fix the energy storage BMS at the test station.
[0036] It should be noted that gaskets are provided at the four corners of the bottom surface of the energy storage BMS, that is, when the energy storage BMS is transported on the conveyor belt 11, there is a spacing between the bottom surface of the energy storage BMS and the conveyor belt 11; the positioning clamping plate 22 is an L-shaped plate, and the side surface of the bottom plate of the L-shaped plate away from the second driving cylinder 60 is an inclined surface. When the positioning clamping plate 22 clamps the energy storage BMS, the inclined surface of the positioning clamping plate 22 can lift the energy storage BMS. That is, during the test, the energy storage BMS does not contact the conveyor belt 11, avoiding the generation of friction between the energy storage BMS and the conveyor belt 11 when the energy storage BMS is fixed at the test station.
[0037] Optionally, a guiding plate 14 is further provided inside the baffle 12, and the guiding plate 14 is located upstream of the conveyor belt 11 at the test station. The guiding plate 14 guides the energy storage BMS to move to the test station.
[0038] An automatic testing device for energy storage BMS disclosed by the utility model has the following specific implementation manner: during the production of the energy storage BMS, the assembled energy storage BMS is conveyed onto the conveyor belt 11; before the energy storage BMS is conveyed to the testing station, the positioning plate 21 descends. When the energy storage BMS is conveyed onto the positioning plate 21 along with the conveyor belt 11, the positioning plate 21 blocks the movement of the energy storage BMS, and then the positioning clamping plate 22 extends and clamps the energy storage BMS to fix the energy storage BMS at the testing station; at this time, the testing circuit board 31 descends, and the testing probe 32 contacts the testing points on the battery management system to test the energy storage BMS; after the testing is completed, the positioning clamping plate 22 retracts, the positioning plate 21 ascends, and the tested energy storage BMS flows downstream along with the conveyor belt 11 to vacate the testing station and wait for testing the next energy storage BMS. The automatic testing device for energy storage BMS of the utility model can be arranged downstream of the energy storage BMS production line to test the assembled energy storage BMS, solves the technical problem that the traditional manual or semi-automatic testing method takes up too much production time, thereby improving the production efficiency of the energy storage BMS and also avoiding the errors and error risks brought by manual testing.
[0039] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
