Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to an OCV testing device for aqueous zinc-ion batteries. Background Technology

[0002] Open-circuit voltage (OCV) testing is a crucial test in the battery industry, primarily used to evaluate the battery's voltage characteristics in an open-circuit state. Open-circuit voltage refers to the potential difference between the positive and negative electrodes when the battery is neither discharging nor charging and is in an open-circuit state. It reflects the battery's electrochemical potential energy in equilibrium. Aqueous zinc-ion wound batteries are a type of aqueous zinc-ion battery structure. They assemble positive and negative electrode materials, separators, and other components in a wound manner, similar to traditional wound lithium-ion batteries, offering advantages such as compact size and high energy density. Current OCV testing mainly relies on manual testing assisted by fixtures. The purpose of OCV testing is to quickly inspect and reject defective aqueous zinc-ion batteries. While existing testing methods also utilize automated equipment for rapid inspection, defective products are generally recorded and rejected in the next process, failing to achieve real-time rejection and requiring further efficiency improvements. Utility Model Content

The upper detection mechanism includes a pair of parallel upper guide rails arranged along the X-axis, each with a matching upper slider. The upper detection mechanism also includes an upper detection frame, with the upper sliders fixedly connected to the upper detection frame. The upper detection frame is equipped with an upper detection seat and an upper detection cylinder that drives the upper detection seat to move up and down.

The rejection slider is connected to a downwardly output rejection cylinder, and the output end of the rejection cylinder is connected to a cylinder clamp.

[0005] The transmission mechanism is used to transport batteries to a predetermined position for testing and then return them to their original position. During testing, the upper and lower testing mechanisms connect the battery electrodes for OCV testing. The upper and lower testing mechanisms can move back and forth along the X-axis, allowing for synchronous row-by-row testing of batteries with high efficiency. The upper testing mechanism is equipped with a linear module and a rejection cylinder.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0032] This utility model provides an OCV testing device for aqueous zinc-ion batteries, such as... Figures 1-8 As shown, the device includes a machine base 1, on which a transmission mechanism 2 capable of back-and-forth transport in the Y-axis direction is provided. Above the transmission mechanism 2, an upper detection mechanism 3 capable of back-and-forth movement in the X-axis direction is provided, and below the transmission mechanism 2, a lower detection mechanism 4 capable of back-and-forth movement in the X-axis direction is provided.

[0033] The transmission mechanism 2 includes a drive shaft 21 and a pair of conveyor belts 22 arranged side by side.

[0034] The upper detection mechanism 3 includes a pair of parallel upper guide rails 31 arranged in the X-axis direction. Each upper guide rail 31 is provided with a matching upper slider 32. The upper detection mechanism 3 also includes an upper detection frame 33. The upper slider 32 is fixedly connected to the upper detection frame 33.

The upper detection frame 33 is provided with an upper detection seat 34 and an upper detection cylinder 35 that drives the upper detection seat 34 to move up and down. The upper detection seat 34 is provided with a plurality of downwardly extending upper detection probes 341. The upper detection probes 341 are linearly arranged along the Y-axis direction and can be arranged in one or more rows. After the upper detection seat 34 drives the upper detection probes 341 to move to a predetermined position, it drives the upper detection probes 341 to move down and contact the battery electrodes, which can realize the simultaneous detection of one or more rows of batteries in the storage frame 24. The upper detection mechanism 3 includes an upper lead screw 36 parallel to the upper guide rail 31. The upper detection frame 33 is provided with an upper transmission block 37 that is matched and connected to the upper lead screw 36.

[0035] The lower detection mechanism 4 includes a pair of parallel lower guide rails 41 arranged in the X-axis direction. Each lower guide rail 41 is equipped with a matching lower slider 42. The lower detection mechanism 4 also includes a lower detection frame 43. The lower sliders 42 are fixedly connected to the lower detection frame 43. The lower detection frame 43 can move back and forth in the X-axis direction guided by the lower sliders 42 along the lower guide rails 41. The lower detection frame 43 is equipped with a lower detection seat 44 and a lower detection cylinder 45 that drives the lower detection seat 44 to move up and down. The lower detection seat 44 is equipped with multiple upwardly extending lower... The detection probe 441 is arranged linearly along the Y-axis and can be set in one or more rows. The lower detection seat 44 drives the lower detection probe 441 to move to a predetermined position and then drives the lower detection probe 441 to move upward and contact the battery electrode.

[0036] The travel trajectories of the lower detection probe 441 and the upper detection probe 341 are in one-to-one correspondence. The number of rows and specific quantities of the lower detection probe 441 and the upper detection probe 341 correspond to each other, ensuring that each battery has a corresponding upper detection probe 341 and lower detection probe 441 for detection.

[0037] The upper inspection frame 33 is equipped with a linear module 39, which has a rejection slider 391 that slides along the Y-axis. The rejection slider 391 is connected to a downward-output rejection cylinder 392. During the movement of the upper inspection frame 33, the rejection slider 391 can reject the batteries in the current row after inspection and remove defective products. The output end of the rejection cylinder 392 is connected to a cylinder clamp, and the removal of defective products is achieved by the cylinder clamp. The cylinder clamp can be implemented using any prior art. The machine 1 is also equipped with a storage box 5, which is located within the stroke of the upper inspection frame 33. The rejection cylinder 392 clamps the rejected defective products into the storage box 5 for discharge and storage.

[0038] Working principle: The batteries to be tested are arranged in an orderly manner in the storage frame 24. The storage frame 24 is placed on the conveyor belt 22. The positioning cylinder 26 extends the positioning block 27. When the storage frame 24 is guided and conveyed to the terminal position along the Y-axis of the limiting plate 25, the corner of the storage frame 24 matches the right-angle structure of the positioning block 27, completing the positioning. The upper motor 38 and the lower motor 48 synchronously drive the upper detection frame 33 and the lower detection frame 43 to move along the X-axis to the predetermined position. The upper detection cylinder 35 and the lower detection cylinder 45 synchronously drive the upper detection seat 34 and the lower detection seat 44 to move towards the battery. The upper detection probe 341 and the lower detection probe 441 are in contact with the electrodes of the battery for detection. The upper detection probe 341 and the lower detection probe 441 are designed with the same number of rows and the number of each row corresponds. When a defective product is found during the detection process, the linear module 39 drives the rejection cylinder 392 to move along the Y-axis to the corresponding position. The rejection cylinder 392 drives the cylinder clamp to move downward to clamp the defective product and return to its original position. The upper motor 38 drives the upper detection frame 33 to move to the corresponding position of the storage box 5. The cylinder clamp places the defective product, and the upper detection frame 33 continues to move to the corresponding position of the untested battery to continue the detection.
