Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing technology, specifically to a waterwheel length setting device for soft-pack power lithium batteries during the material feeding process of the formation process, and more particularly to a waterwheel length setting device for soft-pack power batteries with floating overvoltage protection. Background Technology

[0002] In the production process of soft-pack power lithium batteries, in order to improve the gripping accuracy and production efficiency of robotic arms, a waterwheel structure is usually used for the centralized setting of large batches of batteries, and then the overhead crane robotic arm grips and puts them into the fixture to complete the formation process.

[0003] The existing waterwheel long setting device usually adopts a rigid frame and a fixed-spacing layer structure. This structure has the following main problems: 1. Because the setting frame is long, it is prone to deformation after long-term use; 2. If the cylinder is adjusted too quickly, it is easy to overpush, thus failing to achieve the expected setting effect.

[0004] Therefore, there is an urgent need to develop a soft-pack power lithium battery waterwheel length adjustment device that can adapt to frame deformation, effectively prevent over-pushing, and provide more uniform and controllable constraint pressure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, such as the easy deformation of long profiles in rigid waterwheel long setting devices and the tendency for "over-push" due to excessively rapid response from automated equipment (such as cylinders), this invention provides a soft-pack power battery waterwheel long setting device with floating overpressure protection. This invention uses a floating mechanism to set the battery, effectively ensuring the battery's positional accuracy without causing overpressure, thus improving the overall production efficiency and feasibility of the equipment.

Each floating unit includes a bushing (200), a guide shaft (201), a spring (202), and a first insulating plate (206). The guide shaft (201) is slidably disposed within the bushing. The spring (202) is sleeved on the guide shaft (201) to provide preload. The first insulating plate (206) is disposed at the front end of the guide shaft (201) and contacts the battery body. The cylinder (102) pushes the long, fixed aluminum profile (108) and the floating mechanism toward the battery. The first insulating plate (206) contacts the battery tabs and compresses the spring (202). When all batteries are pushed to the positioning mechanism, the spring (202) remains compressed and provides continuous elastic force to prevent overpressure on the batteries. In the free state, the spring (202) has a certain elastic force to keep the first insulating plate in a horizontal straight state. The control mechanism includes a PLC and a solenoid valve. The PLC is used to control the linkage between the device and other equipment, and the solenoid valve is used to control the extension and retraction of the cylinder (102).

[0007] Furthermore, it also includes a positioning mechanism located on the other side of the feeding water cart (150) to provide a reference for battery setting, which can be adjusted up and down and left and right according to different battery models; the positioning mechanism includes an adjustable support plate (300), a fixing plate (301), an aluminum profile (302) and a second insulating plate (303), the aluminum profile (302) is provided with the second insulating plate (303), the fixing plate (301) is provided with multiple sets of threaded holes, the fixing plate (301) is installed on the aluminum profile (302) through the threaded holes, and the fixing position of the front and rear threaded holes can be adjusted to meet the needs of different battery models; the support plate (300) is located at the bottom of the fixing plate (301) and fixed on the aluminum profile on the other side of the feeding water cart (150), the support plate (300) is provided with a U-shaped hole, which can be adjusted up and down.

[0008] Furthermore, the support assembly includes a waterwheel length adjustment support plate (100) and a waterwheel length adjustment base plate (101). The waterwheel length adjustment base plate (101) is fixed on an aluminum profile on one side of the feeding waterwheel (150). The waterwheel length adjustment support plate (100) is installed at the bottom end of the waterwheel length adjustment base plate (101). The height of the waterwheel length adjustment support plate (100) can be adjusted up and down to support the waterwheel length adjustment base plate (101).

[0009] Furthermore, an insulating plate fixing plate (205) is provided at the front end of the guide shaft (201), and the first insulating plate (206) is mounted on the insulating plate fixing plate (205).

[0010] Furthermore, there are three linear guides (103), and each linear guide is equipped with two sliders (104).

[0011] Furthermore, the floating unit also includes a flat washer (203) and a retaining ring (204). The flat washer (203) is disposed between the bushing (200) and the guide shaft (201). The retaining ring (204) is disposed at the end of the guide shaft to prevent the guide shaft (201) from coming out of the bushing (200).

[0012] Furthermore, the number of floating units is twelve, and the corresponding first insulating plate (206) is installed by four sets of insulating plate fixing plates (205).

[0013] Furthermore, the stroke of the cylinder (102) is greater than the sum of the length of the battery tab and the set distance, so as to avoid interference when the overhead crane robot grips the battery.

[0014] Furthermore, the gap between the two long, fixed aluminum profiles (108) is 100 mm, and they are reinforced by reinforcing ribs.

[0015] In this invention, a long setting mechanism is installed on the profiles on both sides of the loading water cart. The loading robot loads batteries into the water cart. After it is full (about 36 batteries), the long setting mechanism sets all the batteries at once so that the overhead crane robot can remove the batteries to complete the next process. Since the setting insulating blocks push the battery tabs to the upper and lower positions respectively, when the cylinder retracts, in order to avoid interference from the setting insulating blocks during the upward movement of the overhead crane robot to pick up the batteries, the cylinder stroke must be greater than the length of the tab plus the setting distance. During the setting process, the cylinder extends, the first insulating plate contacts the upper and lower sides of the battery tabs, and the spring begins to compress. When all the batteries are pushed to the position of the positioning mechanism, the battery setting is completed. At this time, the spring still maintains its elasticity to avoid over-pressure on the batteries.

[0016] The core concept of this utility model is to transform the traditional rigid shelf structure into a "floating" shelf structure and combine it with a mechanical limiting mechanism, so that when the device is subjected to excessive external thrust ("over-push"), it can absorb the impact force through the displacement of the floating layer, and prevent the excessive force from being directly transmitted to the battery body, thereby achieving effective protection of the battery.

[0017] Compared with the prior art, the beneficial effects of this utility model are reflected in: 1. This utility model uses a floating mechanism to adjust the battery, which can effectively ensure the battery's positional accuracy and prevent overvoltage, thereby improving the overall production efficiency and feasibility of the equipment. The structure is relatively simple and easy to modify or integrate into existing waterwheels.
