Description

[Technical Field]

[0001] This utility model belongs to the technical field of battery cell manufacturing equipment, and in particular relates to a high-efficiency testing device for battery cells. [Background Technology]

[0002] After solar cells are manufactured, they are graded according to their photoelectric conversion efficiency to maximize profitability. The testing of solar cell photoelectric conversion efficiency is known in the industry as IV testing. To improve solar cell production efficiency, numerous automated IV testing devices for solar cells have emerged on the market.

[0003] Existing patent CN209327540U discloses a battery cell efficiency testing device. A feeding conveyor line and a discharging conveyor line are arranged opposite each other, with a rotating mechanism in between to facilitate material flow. The rotating mechanism is positioned as a feeding station at the end of the feeding conveyor line and a discharging station at the beginning of the discharging conveyor line. A testing station is located between the feeding and discharging stations, and a testing camera is installed at the testing station. Battery cells from the end of the feeding conveyor line are transported to the rotating mechanism by a handling mechanism, then rotated to the testing station for testing. After testing, they are rotated back to the discharging station and then transported back to the discharging conveyor line by the handling mechanism. Because the battery cell position accuracy is very high during testing, a first camera is installed above the end of the feeding conveyor line to guide the feeding and handling mechanism in correcting the battery cell loading position. Simultaneously, a second camera is installed above the feeding station to guide the testing probe at the testing station in correcting its position. This device has the following drawbacks:

[0004] (1) The rotating mechanism has four stations, but only three of them are effectively utilized, resulting in wasted stations;

[0005] (2) The second camera at the loading station can only take pictures after the battery cells are placed on it. Therefore, the operation time at the loading station includes loading time and taking pictures. As the production cycle of battery cells gradually increases, this method cannot meet the production needs of battery cells with higher cycle times.

[0006] Therefore, it is necessary to provide a new high-efficiency testing device for solar cells to solve the above-mentioned technical problems. [Utility Model Content]

[0007] The main objective of this invention is to provide a high-efficiency testing device for solar cells, which can meet the needs of higher-speed solar cell testing.

[0008] This utility model achieves the above-mentioned objectives through the following technical solution: a high-efficiency battery cell testing device, comprising a rotating mechanism, a feeding conveyor line, a feeding mechanism, a plurality of first cameras, a testing mechanism, a discharging mechanism, and a discharging conveyor line; a feeding station, a first camera, a testing station, and a discharging station are sequentially arranged around the rotating mechanism; the feeding conveyor line is arranged corresponding to the feeding station; the first cameras are arranged corresponding to the first camera and located below the rotating mechanism; the testing mechanism is arranged corresponding to the testing station; the discharging conveyor line is arranged corresponding to the discharging station; the feeding mechanism transfers the battery cells on the feeding conveyor line to the rotating mechanism; the discharging mechanism transfers the battery cells on the rotating mechanism to the discharging conveyor line; a light source is arranged above the testing station.

[0009] Furthermore, the rotating mechanism includes a rotating support for rotating motion and a plurality of adsorption fixtures arranged at equal angles on the rotating support.

[0010] Furthermore, the adsorption fixture includes a support frame and a plurality of adsorption support rods disposed in the support frame for adsorbing and supporting the battery cells.

[0011] Furthermore, the support frame is a hollow rectangular frame structure.

[0012] Furthermore, the adsorption support rod forms at least two adsorption support positions, which adsorb two battery halves respectively.

[0013] Furthermore, both the loading mechanism and the unloading mechanism include an XZ transfer module for horizontal transfer and lifting drive, and an adsorption component disposed at the movable end of the XZ transfer module.

[0014] Furthermore, the feeding conveyor line is equipped with a alignment module for aligning the battery cells around their perimeter.

[0015] Furthermore, the detection mechanism includes a fine-tuning mechanism for fine-tuning the position of the battery cell based on the position information of the first camera, and a test connection module driven by the fine-tuning mechanism.

[0016] Furthermore, the test connection module uses a probe board or circuit board to achieve electrical connection with the battery cells.

[0017] Furthermore, it also includes a second photographing station located at the end of the feeding conveyor line, with a second photographing camera installed below the second photographing station; the feeding mechanism and the unloading mechanism also include an adjustment module that drives the XZ transfer module to perform horizontal position and angle correction; the adjustment module performs correction adjustment according to the position of the battery cell obtained by the second photographing camera.

[0018] Compared with existing technologies, the advantages of this utility model's high-efficiency battery cell testing equipment are as follows: By sequentially arranging a loading station, a first photographing station, a testing station, and a unloading station around the rotating mechanism, with the loading station connected to the loading conveyor line and the loading mechanism, and the unloading station connected to the unloading conveyor line and the unloading mechanism; a camera is installed at the first photographing station to photograph the battery cells on the rotating mechanism, and a testing mechanism is installed at the testing station to correct the deviation and perform power testing on the battery cells. Through the above layout design, only the loading of battery cells is performed at the loading station, without the need for photographing. However, the photographing is not eliminated but is performed at the first photographing station, allowing the loading and photographing of battery cells to be carried out simultaneously. Compared with the sequential execution of loading and photographing, this can shorten the production cycle and improve testing efficiency. In addition, all four stations arranged around the rotating mechanism are effectively utilized, solving the problem of station waste. [Attached Image Description]

Detailed Implementation Methods

[0030] Example 1:

[0031] Please refer to Figures 1-4This embodiment is a high-efficiency battery cell testing device 100, which includes a rotating mechanism 1, a feeding conveyor line 2, a feeding mechanism 3, a plurality of first cameras 4, a testing mechanism 5, a discharging mechanism 6, and a discharging conveyor line 7. A feeding station, a first camera station, a testing station, and a discharging station are sequentially arranged around the rotating mechanism 1. The feeding conveyor line 2 is positioned corresponding to the feeding station. The first cameras 4 are positioned corresponding to the first camera station and located below the rotating mechanism 1. The testing mechanism 5 is positioned corresponding to the testing station. The discharging conveyor line 7 is positioned corresponding to the discharging station. The feeding mechanism 3 transfers the battery cells from the feeding conveyor line 2 to the rotating mechanism 1. The discharging mechanism 6 transfers the battery cells from the rotating mechanism 1 to the discharging conveyor line 7. A light source (not shown in the figure) is positioned above the testing station.

[0032] With the above layout design, the loading station only handles the loading of battery cells, without requiring battery cell photography. Battery cell photography is not eliminated but is performed at the first photography station, allowing loading and photography to occur simultaneously. This shortens the production cycle and improves testing efficiency compared to loading and photography occurring sequentially. Furthermore, the four stations surrounding the rotating mechanism 1—loading, photography, inspection, and unloading—are all effectively utilized, solving the problem of wasted workstation space.

[0033] In this embodiment, the rotating mechanism 1 includes a rotating support 11 for rotating motion and a plurality of adsorption fixtures 12 arranged at equal angles on the rotating support 11. Each adsorption fixture 12 includes a support frame 121 and a plurality of adsorption support rods 122 disposed within the support frame 121 for adsorbing and supporting the battery cells. The support frame 121 is a hollow rectangular frame structure.

[0034] The feeding conveyor line 2 is equipped with a alignment module 21 for aligning the battery cells around their perimeter. The alignment module 21 is positioned as close as possible to the feeding mechanism 3 to minimize the movement distance of the aligned battery cells, ensuring that the aligned battery cells do not shift in position before being picked up by the feeding mechanism 3, thereby ensuring the accurate positioning of the battery cells picked up by the feeding mechanism 3.

[0035] Both the loading mechanism 3 and the unloading mechanism 6 include an XZ transfer module 31 for horizontal transfer and lifting drive, and an adsorption component 32 located at the moving end of the XZ transfer module 31.

[0036] The testing mechanism 5 can be the testing mechanism found in existing battery half-cell photoelectric efficiency testing equipment, which requires a fine-tuning mechanism and a test connection module driven by the fine-tuning mechanism. The test connection module can use a probe board for electrical connection or a circuit board for electrical connection, such as the combination of a "calibration mechanism" and a "testing machine" disclosed in patent CN209411201U. Its structure will not be described in detail in this embodiment.

[0037] To ensure that the direction of the battery cells on the feeding conveyor line 2 and the unloading conveyor line 7 is consistent, the unloading mechanism 6 is also equipped with a rotary drive component (not shown in the figure) that drives the adsorption assembly 32 to rotate. The unloading mechanism takes the battery cells from the rotating mechanism 1 at the unloading station, then rotates them horizontally by 90 degrees before placing them on the unloading conveyor line 7.

[0038] Example 2:

[0039] This embodiment has a basically the same structure as Embodiment 1, the difference being:

[0040] In this embodiment, the loading mechanism 3 and the unloading mechanism 6 further include an adjustment module 33 for driving the XZ transfer module 31 to perform horizontal position and angle correction. The structure of the adjustment module 33 can adopt the structure in the prior art, and its structure will not be described in detail in this embodiment.

[0041] This embodiment also includes a second photo-taking station located at the end of the feeding conveyor line 2. A second camera (not shown in the figure) is provided below the second photo-taking station. The adjustment module 33 performs correction adjustment based on the position of the battery cell obtained by the second camera.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
