Description

Technical Field

[0001] This utility model relates to the field of lithium battery module manufacturing technology, and in particular to a double-layer electrical testing device. Background Technology

[0002] In the manufacturing process of lithium battery modules, after the cells are assembled into modules, the modules need to undergo electrical performance testing. Only modules that pass the electrical tests can proceed to the next stage of the process, and then proceed to the PACK process.

[0003] Existing electrical testing devices for lithium battery modules are mostly single-station devices located on the conveyor line. These devices sequentially test the modules within each pallet according to the order in which the pallets move along the conveyor. This method is suitable for large modules or production line speed requirements that are not high. For applications with high production line speed requirements, two or more electrical testing devices are often arranged side-by-side, or several devices are symmetrically mirrored on both sides of a parallel double conveyor line. However, these single-station electrical testing devices cannot meet the high speed requirements of production lines. Using multiple devices also increases equipment costs, increases line length, and reduces factory utilization.

[0004] Therefore, in order to meet the high-speed production line requirements, it is particularly important to improve the electrical testing efficiency of lithium battery modules while achieving low production line equipment costs and high factory utilization efficiency. Utility Model Content

[0005] The purpose of this invention is to address the technical problem that in existing technologies, when production line cycle time requirements are high, the common practice of arranging two or more electrical measuring devices side by side, or symmetrically mirroring several electrical measuring devices on both sides of parallel double conveyor lines, increases production line equipment costs, increases production line length, and reduces factory utilization.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer electrical testing device, comprising an outer frame, a vertical lifting mechanism provided on one side of the outer frame; an electrical testing station provided inside the outer frame; and a sensing component provided above the electrical testing station.

[0007] Both the vertical lifting mechanism and the electrical testing station are equipped with conveyor lines.

[0008] The vertical lifting mechanism is used to lift the module; the electrical testing station is used to fix the module; the sensing component is used to perform electrical testing data on the module according to instructions; and the conveyor line is used to move the module horizontally.

[0009] The outer frame serves as a support device for the vertical lifting mechanism, electrical testing station, sensing components, and conveyor line. The module is placed on the conveyor line of the vertical lifting mechanism, which then lifts it to the height of the electrical testing station. The module is then transported to the conveyor line of the electrical testing station via the vertical lifting mechanism. After the electrical testing station secures the module, the sensing components perform electrical testing data analysis on the module according to instructions. Once the test is complete, the conveyor line of the electrical testing station sends the module back to the conveyor line of the vertical lifting mechanism, which lowers the module and moves it away, thus completing one electrical testing process. This operation is repeated continuously, ensuring that there is always a module performing electrical testing at the electrical testing station. The vertically arranged electrical testing station and sensing components not only guarantee the testing efficiency of the module but also reduce the production line length and floor space required.

[0014] Preferably, the module is placed on a tray, and the bottom of the tray is provided with pin holes.

[0015] Preferably, two sets of electrical testing stations and sensing components are arranged vertically within the outer frame.

[0016] Preferably, the outer surface of the outer frame is provided with an equipment sealing plate and a maintenance door.

[0017] Preferably, the bottom of the outer frame is provided with feet.

[0018] Preferably, casters are provided at the bottom of the outer frame.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. In this utility model, the electrical testing stations and sensing components arranged vertically not only ensure the testing efficiency of the module, but also reduce the production line length and the floor space occupied; at the same time, the double-layer electrical testing stations arranged vertically meet the high cycle time requirements of the production line, improve electrical testing efficiency, shorten the production line length, reduce the production line equipment cost, and improve the utilization rate of the factory.

[0030] Please see Figures 1-7 This utility model provides a technical solution: a double-layer electrical testing device, comprising: an outer frame 1.1, a vertical lifting mechanism 2 provided on one side of the outer frame 1.1; an electrical testing station 3 provided inside the outer frame 1.1; and a sensing component 4 provided above the electrical testing station 3.

[0031] Both the vertical lifting mechanism 2 and the electrical testing station 3 are equipped with conveyor lines 5;

[0032] The vertical lifting mechanism 2 is used to lift the module 7; the electrical testing station 3 is used to fix the module 7; the sensing component 4 is used to test the electrical data of the module 7 according to the instructions; and the conveyor line 5 is used to move the module 7 horizontally.

[0033] The outer frame 1.1 serves as the supporting device for the vertical lifting mechanism 2, the electrical testing station 3, the sensing component 4, and the conveyor line 5. The module 7 is placed on the conveyor line 5 of the vertical lifting mechanism 2. The vertical lifting mechanism 2 lifts the module 7 to the height of the electrical testing station 3. The module 7 is then transported to the conveyor line 5 of the electrical testing station 3 via the conveyor line 5 of the vertical lifting mechanism 2. After the electrical testing station 3 fixes the module 7, the sensing component 4 performs electrical testing on the module 7 according to instructions. After the test is completed, the conveyor line 5 of the electrical testing station 3 sends the module 7 back to the conveyor line 5 of the vertical lifting mechanism 2. The vertical lifting mechanism 2 lowers the module 7 and moves it away, thus completing one electrical testing process. This operation is repeated continuously, ensuring that the electrical testing station 3 always has a module 7 performing electrical testing. The vertically arranged electrical testing station 3 and sensing component 4 ensure the testing efficiency of the module 7 while reducing the production line length and floor space.

[0034] In this embodiment, the vertical lifting mechanism 2 includes: a lifting frame 2.5, a lifting motor 2.1 is provided at the bottom of the lifting frame 2.5, and an actuating screw 2.4 is connected to the output shaft of the lifting motor 2.1 through a lifting reducer 2.2. The actuating screw 2.4 passes through the bottom of the lifting frame 2.5 to the top of the lifting frame 2.5 and is rotatably connected to the lifting frame 2.5; a conveyor line 5 is connected to the actuating screw 2.4.

[0035] The lifting motor 2.1 drives the actuator screw 2.4 to rotate. The conveyor line is threadedly connected to the actuator screw 2.4. The conveyor line is located between the lifting frame 2.5 and cannot rotate, thus realizing up and down movement. While the conveyor line 5 is connected to the actuator screw 2.4, it can also be slidably connected to the lifting frame 2.5 on both sides through the guide rail 2.3.

[0036] In this embodiment, the electrical testing station 3 includes: an electrical testing motor 3.1, whose output end is connected to an electrical testing cylinder 3.3 via an electrical testing reducer; a lifting positioning plate 3.5 is provided at the output end of the cylinder; a positioning pin 3.6 is provided on the lifting positioning plate 3.5; a conveyor line is provided at the lifting positioning plate 3.5; a first guide linear bearing 3.4 can be provided on the lifting positioning plate 3.5. The module 7 is placed on the tray 6, the tray 6 is placed on the conveyor line 5, and a pin hole 6.1 is provided at the bottom of the tray 6.

[0037] The vertical lifting mechanism 2's conveyor line 5 horizontally transports the pallet 6 and module 7 to the electrical testing station 3's conveyor line 5, ready for electrical testing. The electrical testing motor 3.1 drives the electrical testing cylinder 3.3 to lift via the electrical testing reducer 3.2, and is guided by the first guide linear bearing 3.4 to lift the pallet 6. The positioning pin 3.6 on the lifting positioning plate 3.5 is inserted into the reserved pin hole 6.1 on the bottom plate of the pallet 6, completing the positioning and fixing of the pallet 6.

[0038] In this embodiment, the sensing component 4 includes: a sensing motor 4.1, the output end of which is connected to a sensing cylinder 4.3 via a sensing reducer 4.2; the output end of the sensing cylinder 4.3 is connected to a probe disk 4.5; an electrical measuring probe 4.6 is provided on the probe disk 4.5; and a second guide linear bearing 4.4 may be provided on the probe disk 4.5.

[0039] Then, the sensor motor 4.1 drives the sensor cylinder 4.3 to push out via the sensor reducer 4.2, and is guided by the second guide linear bearing 4.4 to press down the probe disk 4.5, causing the electrical test probe 4.6 to contact the module 7 to be tested. According to the instructions, the relevant electrical test data is measured. The cable signal line is routed according to the requirements. The cable is attached to the double-layer electrical test device structure to transmit the electrical test data and related control commands of the module 7.

[0040] In this embodiment, the conveyor line includes: two symmetrically arranged conveyor frames 5.1, each conveyor frame 5.1 having a conveyor line body 5.2. One conveyor frame 5.1 has a variable frequency motor 5.3 mounted on it, and the output end of the variable frequency motor 5.3 is connected to the conveyor line body 5.2 on the conveyor frame 5.1 via a conveyor reducer 5.4. A drive shaft 5.5 connects the conveyor frames 5.1. The conveyor line body 5.2 can be one of a common double-speed chain line, roller line, or belt line, and can be selected according to specific requirements.

[0041] The rotation of the variable frequency motor 5.3 can drive the conveyor line 5.2 to move, for example, by the belt. The belt and the variable frequency motor 5.3 can be connected by pulleys. The belt on the two conveyor frames 5.1 can be moved by the rotating shaft to complete the transportation of objects above it. The two sets of conveyor frames 5.1 in the electrical testing station 3 can be set on both sides of the lifting and positioning plate 3.5 so as not to affect its lifting.

[0042] In this embodiment, two sets of electrical testing stations 3 and sensing components 4 are arranged inside the outer frame 1.1, one above the other.

[0043] The two sets of electrical testing stations 3 and sensing components 4 arranged vertically within the frame can take turns testing the module 7. When there is no module 7 in either the upper or lower electrical testing station 3, the vertical lifting mechanism 2 will drive the module 7 to be tested to rise or fall and horizontally transport it to the electrical testing station 3 for electrical testing, thereby improving the testing efficiency of the module 7 without increasing the floor space.

[0044] In this embodiment, the outer surface of the outer frame 1.1 is provided with an equipment sealing plate and a maintenance door. The bottom of the outer frame 1.1 is provided with feet 1.2 and casters 1.3. This facilitates the maintenance and transportation of the device.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
