Description

Technical Field

[0001] The utility model relates to the technical field of battery detection equipment, in particular to a DCIR testing equipment. Background Art

[0002] At present, in the battery production process, DCIR (direct current internal resistance) testing equipment is often used to test the battery cells. After the battery cells are divided into components, DCIR testing (direct current internal resistance testing) is required to confirm the consistency of the internal resistance of the battery cells. The DCIR test is an indirect test, that is, the voltage and current of the battery cells are discretely tested, and the internal resistance value of the battery cells is calculated based on the tested voltage and current.

[0003] In the traditional DCIR process, multiple DCIR inspection machines are located on one side of the same logistics line. After the pallets enter the DCIR inspection machine and are inspected, they are transported out from the same direction and return to the logistics line. Uninspected pallets and inspected pallets share the same logistics line. The blockage of the logistics line affects the normal performance of the DCIR inspection machine, causing materials in the adjacent processes to wait or be congested, resulting in a waste of resources.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , in the embodiment of the present invention, a DCIR test device includes a loading line 15 and an unloading line 17. The loading line 15 and the unloading line 17 are partially arranged in parallel. A plurality of detection parts are provided between the loading line 15 and the unloading line 17. The feeding end of the detection part is communicated with the loading line 15, and the discharging end of the detection part is communicated with the unloading line 17. In this embodiment, there are three detection parts and the three detection parts are arranged in parallel.

[0024] The detection part includes a lower frame 1 and an upper frame 2 arranged at the upper end of the lower frame 1. A detection space is provided between the lower frame 1 and the upper frame 2. A lifting mechanism 3 and a roller transmission mechanism 4 are provided at the upper end of the lower frame 1. An avoidance space for avoiding the lifting mechanism 3 is provided in the middle of the roller transmission mechanism 4. The lifting mechanism 3 includes a substrate and a lifting motor 30 arranged at the lower end of the substrate. An ultra-high detection sensor 31, a feeding detection sensor 32, a transmission-in-place sensor 33, an anti-reverse placement sensor 34, and an in-place detection sensor 35 are provided on the substrate.

[0025] A detection mechanism 5 is provided at the lower end of the upper frame 2. The detection mechanism 5 is located above the lifting mechanism 3. A power module 11 is provided inside the upper frame 2. An extraction fan 12 for cooling the power module is provided on the upper frame 2. A voltage and current acquisition module 10 is provided inside the upper frame 2. The detection mechanism 5 includes a detection head. The voltage and current acquisition module 10 is communicated with the detection mechanism 5 through a switch 9. A barcode scanner 14 is provided at the lower end of the upper frame 2. The barcode scanner 14 is located obliquely above the lifting mechanism 3. A display screen 7 and a buzzer 13 are provided at the front end of the upper frame 2. A button group 8 is provided at the front end of the upper frame 2. The button group 8 includes a start button, a stop button, an emergency stop button, a reset button, a maintenance selection button, and a manual-automatic switching button.

[0026] When the utility model is in use, the battery to be tested is placed in the tray 16 and transmitted through 15. After the tray 16 is transmitted to the position of the detection part, the detection equipment is started. The tray 16 enters the roller transmission mechanism 4 through the feeding line 15 and moves into the detection space between the lower frame 1 and the upper frame 2 through the roller transmission mechanism 4. When the sensor on the lifting mechanism 3 detects that the tray 16 is in place, the lifting mechanism 3 is started, and then the tray 16 is lifted upward by a certain height. When the detection head of the detection mechanism 5 contacts the battery, the lifting stops. Then, the battery is detected through the detection mechanism 5 and the voltage and current acquisition module 10. At the same time, the battery information is collected through the barcode scanner 14. Furthermore, the detection result can be bound to the battery. After the detection is completed, the lifting mechanism 3 drives the tray 16 to descend, and then the tray is moved to the discharging line 17 through the roller transmission mechanism 4. Since the feeding line 15 and the discharging line 17 in this application are locally arranged in parallel, and at the parallel end, a plurality of detection mechanisms are arranged, so that detection and processing can be carried out simultaneously. Moreover, by feeding and discharging the battery tray at both ends, the blockage caused by the feeding and discharging on the same logistics line is alleviated, and the performance realization degree of the DCIR detection equipment is improved.
