Problems solved by technology

[0003] However, in the existing detection technology, it is basically completed by manual operation of detection equipment, and the efficiency is extremely low
In order to improve the detection efficiency, the detection and clamping are also completed by intelligent equipment, but the above two operations are discontinuous, that is, the detection is performed after the clamping is completed, and the unqualified or qualified ones are separated by manpower after the detection. Stability during battery testing and test efficiency are negatively affected
Moreover, a lot of labor is required in the process of linking each process, which increases labor costs.

Embodiment 1

[0051] Such as figure 1 As shown, the frame 1 is used to be placed on the ground to install and support other components of the testing equipment. The drum wire body unit 2 is located in the frame 1, the drum wire body unit 2 includes a driving part and a wire body part, and the driving part is used to drive the transportation of the wire body part; the drum wire body unit 2 It can be realized by the more commonly used conveying rollers in the prior art, so it will not be described in detail. It also includes a battery 4 tray 3 placed on the line body, and the battery 4 tray 3 is used to arrange and collect the batteries 4 in an orderly manner; the battery 4 tray 3 is removed under the action of the line body Send transport.

[0052] In order to realize the detection function, the battery 4 OCV detection equipment also includes: a detection unit 5 arranged inside the frame 1, and the detection unit 5 includes: an X-axis assembly 8, a Z-axis assembly 9, and an OCV detection a...

Embodiment 2

[0074] In the first embodiment above, the roller 606 used by the cable unit 6 realizes the conveying function. However, in the process of use, it was found that when the unqualified battery 4 was clamped to the drawstring unit 6 for loosening and unloading, it was difficult to ensure that the battery 4 would not shake (due to the lighter weight of the battery), that is, the battery 4 When being put down, the front end or the rear end of the battery 4 will be stuck in the adjacent roller 606 due to the instability when placed, and cannot be transported normally, resulting in congestion.

[0075] Therefore, the inventor has made further improvements to the drawstring unit 6 in order to solve the above problems: as Figure 6 to Figure 8 As shown, the drawstring unit 6 includes: a plurality of stands 601, a conveying plate that spans the stand 601 and is fixedly connected with the stand 601, and is mirror-symmetrically arranged on the conveying plate. The support plate 608, the t...

Abstract

The invention discloses battery OCV detection equipment and a detection method thereof, which belong to the technical field of detection equipment. The detection equipment comprises a rack, a roller line body unit, a battery tray, a detection unit, a strip line pulling unit and a test instrument platform, wherein the rack is used for installing other parts of the detection equipment; the roller line body unit is arranged in the rack and comprises a driving part and a line body part, and the driving part is used for driving the line body part to be transported; the battery tray is placed in theline body part; the battery tray is used for orderly arranging and collecting the batteries; the battery tray is conveyed and transported under the action of the line body part; the detection unit isarranged in the rack; the strip line pulling unit is used for conveying out the unqualified batteries taken out by a clamping jaw assembly; and the test instrument platform is fixed on the rack. By arranging the roller line body unit, the X-axis assembly, the Z-axis assembly, the OCV detection assembly, the regulation and control assembly, the clamping jaw assembly and the strip line pulling unit, overall mechanical intelligence of battery OCV detection is achieved, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, and in particular relates to a battery OCV detection equipment and a detection method thereof. Background technique [0002] Lithium batteries need to undergo OCV (Open Circuit Voltage, open circuit voltage) test after completion of formation, capacity separation, and labeling. Through OCV test, the K value of the square lithium battery can be obtained (K value refers to the battery’s K value per unit time. Voltage drop, reflecting lithium battery self-discharge rate), current, voltage, capacity and other parameters, in order to sort out lithium batteries with unqualified electrochemical parameters to ensure the quality of the finished battery. [0003] However, in the existing detection technology, the detection equipment is basically completed by manual operation, and the efficiency is extremely low. In order to improve the detection efficiency, the detection and clamping are also ...
