[0002] During the manufacturing process of lithium battery modules, after the battery cells are assembled into modules, electrical performance testing of the modules is required. Only the modules that pass the electrical testing can flow into the subsequent processes and then undergo the PACK process.

[0003] Existing electrical testing devices for lithium battery modules mostly have only one measurement station, which cannot meet the high electrical testing beat requirements of the module production line, or there are areas for improvement in their equipment structure and the cost of equipment components used is too high, etc., which is not conducive to cost reduction and efficiency improvement.

[0004] CN119224378A, an energization testing device for a new energy battery pack, provides a device for multi-group battery energization testing. However, it occupies a large area, has many restrictions on the battery structure, and at the same time, it is difficult to expand, and it also cannot meet the high electrical testing beat requirements of the module production line.

[0005] Therefore, in order to meet the high beat requirements of the module production line, on the premise of being able to achieve less cost of the electrical testing equipment for the module production line and higher utilization efficiency of the factory building, how to improve the electrical testing efficiency of lithium battery modules is particularly important. Summary of the Invention

[0006] The purpose of the present invention is to provide a multi-bin electrical testing device. By configuring a multi-bin electrical testing device on the lithium battery module production line, through the setting of multiple layers of electrical testing bins, the electrical testing data of the modules in multiple trays can be measured, meeting the high beat requirements of the production line, and being able to reduce the cost of production line equipment and improve the utilization rate of the factory building.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a multi-bin electrical testing device, including a tray, an outer frame assembly, a vertical lifting mechanism, electrical testing bins, a detection component, and a conveyor line; The tray is used for loading battery modules to be electrically tested; The vertical lifting mechanism, the electrical testing bins, and the detection component are all installed on the outer frame assembly; At least two layers of electrical testing bins are installed on the outer frame assembly in the vertical direction; each layer of electrical testing bins includes at least one electrical testing bin for receiving the inflowing trays; The detection component is arranged above each electrical testing bin for detecting the battery modules to be electrically tested in the trays flowing into the electrical testing bins; The vertical lifting mechanism is used for transporting the tray to the height of each layer of electrical testing bins; The conveyor line is used to convey the pallet between the vertical lifting mechanism and the electrical measurement bin.

[0008] The effects achieved by the above settings are as follows: By setting up multiple layers of electrical measurement bins, the capacity of the electrical measurement device is effectively increased, and the electrical measurement data of the modules in multiple pallets can be measured, meeting the high-tempo requirements of the production line, reducing the equipment cost of the production line, and improving the utilization rate of the factory building.

[0012] The effects achieved by the above settings are as follows: The frequency conversion motor, the speed reducer, the transmission shaft, and the conveyor line body are sequentially connected together, and the above components are installed on the frame. The motor provides power to drive the transmission shaft to rotate, and then drives the conveyor line body to move, driving the pallet on the line body to move to the corresponding position. Alternatively, in this application, the transmission shaft can also be driven by the frequency conversion motor to rotate and transmit power, driving the conveyor line body to rotate and move to achieve the transportation function.

[0013] Furthermore, both the conveyor line body 1 and the conveyor line body 2 include multiple conveyor belts that rotate synchronously through a transmission shaft.

[0014] The effects achieved by the above settings are as follows: The structure of the conveyor line body is relatively simple and easy to manufacture.

[0015] Furthermore, either the conveyor line body 1 or the conveyor line body 2 is any one of a double-speed chain, a roller, or a belt.

[0017] Further, each layer of the electrical measurement bins includes multiple columns of electrical measurement bins distributed horizontally; The lifting conveyor line guides each column of electrical measurement bins; and the number of lifting conveyor lines is the same as the number of columns of electrical measurement bins on each layer; The bin conveyor line guides each electrical measurement bin, and the number of bin conveyor lines is the same as the total number of columns of electrical measurement bins on all layers.

[0022] The effects achieved by the above settings: The servo motor, the reduction gear, and the actuating lead screw are sequentially connected together and installed on the lifting frame. The motor provides power to drive the screw to rotate, and then drives the frame of the lifting mechanism conveyor line installed on the actuating lead screw to move up and down. The guide rail is also installed on the frame to guide the frame of the conveyor line to move up and down, and bring the pallet to be electrically measured to the corresponding height.

[0023] The vertical lifting mechanism, as the actuator and power source for the lifting action of the multi-bin electrical measurement device, is installed at the outer frame assembly, drives the pallet in the conveyor line on the lifting component to rise or fall to the height of the electrical measurement bin, and transfers the pallet to the electrical measurement bin through the conveyor line of the vertical lifting mechanism.

[0024] Further, the electrical measurement bin includes a driving cylinder, a guiding linear bearing I, and a jacking positioning plate; The driving cylinder is fixed on the outer frame assembly and is connected to the lifting and positioning plate through a linear guiding bearing 1. The lifting and positioning plate is arranged below the bin conveyor line and is used to lift the tray on the bin conveyor line to below the detection assembly.

For example, for the conveyed tray with pin holes at its bottom, the lifting plate at the lifting and positioning station installs positioning pins at the positions corresponding to the pin holes. The lifting plate is lifted and pushed out, and then the pins are inserted into the pin holes to complete the precise positioning of the conveyed tray assembly.

The probe disc assembly is installed at the bottom of the execution end of the electric cylinder and includes a probe disc mounting plate and probes connected below the probe disc mounting plate. The detection servo motor is connected to the electric cylinder through the detection reduction gear, and thus drives the electric cylinder to eject through the detection reduction gear, pressing down the probe disc assembly and driving the probes to contact the battery module to be electrically measured.

[0028] The effects achieved by the above settings are as follows: By pressing down the probe disc and cooperating with the lifting mechanism of the electrical measurement bin, the inspection of the battery module to be electrically measured is realized.

[0029] Furthermore, the probe disc assembly also includes cable signal lines, which are used to transmit module electrical measurement data and related control instructions.

The positioning pins 3.6 and the positioning holes can achieve precise positioning. The positioning pins 3.6 are used to precisely position the components conveyed by the logistics line. For example, for the conveyed tray 6 with pin holes 6.1 at its bottom, the jacking plate at the jacking positioning station installs the positioning pins 3.6 at the positions corresponding to the pin holes 6.1. The jacking positioning plate 3.5 is lifted and pushed out, and then the positioning pins 3.6 are inserted into the pin holes 6.1 to complete the precise positioning of the conveyed tray 6 component.

[0066] The operation method of this electrical test device is as follows: Appendix Figure 1 and Appendix Figure 2 are the general assembly of the multi-bin electrical test device, and Appendix Figure 3 、Appendix Figure 4 、Appendix Figure 5 、Appendix Figure 6 、Appendix Figure 7 are the components of the multi-bin electrical test device.

[0067] First, after the battery module 7 to be electrically tested is transferred to the electrical test station along the logistics line through the tray 6, according to the program control, the tray 6 flows to the position of the lifting mechanism conveyor line 51. The vertical lifting mechanism 2 drives the conveyor line 5 of the vertical lifting mechanism 2 to rise or fall to the same height as the upper or lower bin conveyor line 52 respectively. Then, the conveyor line 5 of the vertical lifting mechanism 2 horizontally conveys the tray 6 to the upper or lower bin conveyor line 52.

[0068] Specifically, when there is no tray in the upper or lower electrical test bin 3, the vertical lifting mechanism 2 drives the tray 6 to be electrically tested to rise or fall and horizontally conveys it into the electrical test bin 3 for preparing for electrical testing. Specifically, after the conveyor lines 5 of the vertical lifting mechanism 2 and the electrical test bin 3 convey the tray 6 in place, there is a stop mechanism to stop it before starting the subsequent operation actions. The stop structure can be set with reference to the existing mature technologies at the present stage and will not be elaborated here.

[0069] The vertical lifting mechanism 2 of the multi-bin electrical measurement device contains two sets of conveyor lines 5, which can receive and transport two pallets 6 at a time. Specifically, during use, according to program control, the vertical lifting mechanism 2 can wait to successively receive two module pallets 6 to be electrically measured from the main line of the line body logistics, and then the vertical lifting mechanism 2 drives the pallet 6 to rise and fall to the height of the electrical measurement bin 3 on the corresponding layer. Then, the two pallets 6 flow into the electrical measurement bin 3 respectively to start electrical measurement. The second situation is that the two sets of conveyor lines 5 in the vertical lifting mechanism 2 receive two pallets 6 that have completed electrical measurement from the electrical measurement bin 3 at a time. Then, after lifting the pallet 6 to the height of the logistics main line, the pallet 6 that has been electrically measured flows back to the logistics main line to continue the subsequent processes. The third situation is that the two sets of conveyor lines 5 of the vertical lifting mechanism 2 respectively carry a module pallet 6 to be electrically measured and a module pallet 6 that has been electrically measured according to program control, and then rise or fall respectively to transfer the pallet 6 to the electrical measurement bin 3 or the line body of the logistics main line.

[0070] After the pallet 6 to be electrically measured flows into the upper and lower electrical measurement bins 3 of the multi-bin electrical measurement device, the lifting and positioning mechanism in the electrical measurement bin 3 operates. The servo motor of the lifting and positioning mechanism drives the electric cylinder 3.3 to lift through a speed reducer (not shown in the figure), and is guided by the guiding linear bearing 3.4 to lift the pallet 6 with electrical measurement. The positioning pin 3.6 on the lifting and positioning plate 3.5 is inserted into the reserved pin hole 6.1 on the bottom plate of the pallet 6 to complete the precise positioning of the pallet 6. Then, the ejecting actuator of the detection component 4 operates. The servo motor 4.1 of the ejecting actuator drives the electric cylinder 4.3 to eject through the speed reducer 4.2, and is guided by the guiding linear bearing 4.4 to press down the probe plate mounting plate 4.5, driving the probe 4.6 to contact the battery module 7 to be electrically measured, and start measuring relevant electrical measurement data according to the instruction. The cable signal line is routed according to requirements, and the cable is attached inside the structure of the multi-bin electrical measurement device to transmit the module electrical measurement data and relevant control instructions.

[0071] After the electrical measurement is completed, the ejecting actuator and the probe plate assembly in the detection component 4 return to their positions, and the lifting and positioning mechanism in the electrical measurement bin 3 also returns to its position. The vertical lifting mechanism 2 drives the conveyor line 51 of the lifting mechanism to the same height as the conveyor line 52 of the bin. The pallet 6 that has completed electrical measurement in the electrical measurement bin 3 flows back to the conveyor line 5 of the vertical lifting mechanism 2, and finally the pallet flows back to the logistics main line, thus completing a complete electrical measurement process. The above operation method is repeated continuously to always keep a pallet 6 in the electrical measurement bin 3 for electrical measurement.

[0072] The present invention has strong practicability and operability. According to practice, it is a reasonable equipment structure that the multi-bin electrical measurement device includes eight electrical measurement bins, which is in a double-row, double-column, double-layer form, and can meet the high-tempo requirements of electrical measurement in the lithium battery module production line, and can fully test the electrical performance data of the modules in eight trays at one time. While meeting the high-tempo requirements of the production line, the multi-bin electrical measurement device can significantly reduce the number of electrical measurement devices, improve the electrical measurement efficiency, shorten the production line length, reduce the production line equipment cost, and improve the utilization rate of the factory building.

[0073] The above embodiments only describe the preferred embodiments of the present invention, and the drawings of the present invention are described according to the electrical measurement device with two layers and a total of eight electrical measurement bins, which does not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
