Description

Technical Field

[0001] The present invention relates to the technical field of soft-pack lithium battery recycling equipment, in particular to a loading tool for recycling soft-pack lithium batteries. Background Art

[0002] The method most commonly used for batch disassembly of waste lithium-ion batteries is the crushing method. However, the recovery rate of the crushing method is relatively low in the recovery of the positive and negative electrode materials, especially the separator material. Therefore, the physical disassembly method, which was previously neglected, has gradually gained the favor of recycling enterprises. However, before the lithium battery is cut and crushed, the waste lithium-ion battery must be discharged. Otherwise, a large amount of heat will be generated due to battery short circuit during the disassembly process, and even dangerous situations such as explosion may occur, causing accidents. Currently, in industry, the safe discharge of waste lithium-ion batteries generally uses a chemical method, that is, directly putting the waste lithium battery into a salt solution and consuming the remaining power in the battery through the electrolysis process. However, this method has potential safety hazards. If the outer shell of the waste lithium battery is slightly damaged, the electrolyte is likely to leak. Once it encounters the solution, highly toxic substances will be generated, and it must be properly disposed of.

[0003] With the rapid development of the national new energy industry, the demand for various new energy batteries has increased significantly, which has led to a great increase in the variety and specifications of lithium batteries. Among them, the changes in the external dimensions of soft-pack lithium batteries in terms of length and thickness are relatively prominent, and there are two ways of the tab distribution of soft-pack lithium batteries, namely bilateral tab distribution and unilateral tab distribution. In the physical disassembly method for recycling such lithium batteries with multiple specifications and dimensions, there is an urgent need for a discharge loading tool that can be compatible with various models of soft-pack lithium batteries. Summary of the Invention

[0029] Embodiment

[0030] As Figure 1 and Figure 2 shown, a loading tooling for recycling soft-pack lithium batteries includes: tooling substrate 1, electric clamp sliding assembly 2, electric clamp support assembly 3, partition pressing component 4, limit block 5 and power connection head 6 (the connection line diagram of the electric clamp and the power connection head is not drawn in the figure).

[0031] The tooling substrate 1 is provided with partition pressing components 4 at intervals side by side, and the intervals form a frame grid 12 for loading soft-pack lithium batteries. One end of the frame grid 12 is provided with a limit block 5 and an electric clamp support assembly 3, and the other end is provided with an electric clamp sliding assembly 2 and a long strip T-shaped sliding hole 11, and the electric clamp sliding assembly 2 can move back and forth along the long strip T-shaped sliding hole 11.

[0032] As Figure 3 and Figure 4 shown, the electric clamp sliding assembly 2 includes a first electric clamp 21, an electric clamp fixing plate 22, a fixed clamp 23, a guide shaft 24, a slide block 25 and a locking handle 26. One end of the guide shaft 24 is fixedly connected to the slide block 25, and the other end is fixedly connected to the electric clamp fixing plate 22 and the first electric clamp 21 through the fixed clamp 23. The height of the first electric clamp 21 can be adjusted up and down by loosening or tightening the fixed clamp 23 to adapt to the corresponding position of the single-pole ear battery. The slide block 25 can move freely in the long strip T-shaped sliding hole 11. After the battery is placed, the slide block 25 can be moved to adjust the clamping position of the first electric clamp 21 and the pole ear. After the position is determined, the locking handle 26 is locked to meet the discharge clamping requirements of different battery lengths.

[0033] As Figures 5 - 7As shown, the electric clamp bracket assembly 3 is composed of a second electric clamp 31, a sliding card seat 32, a slide groove 33 and a bracket 34. The bracket 34 is fixedly connected with a slide groove 33, and a first slideway 331 is provided on the slide groove 33, and equidistant circular holes 332 are provided on both sides thereof. The bottom surface of the second electric clamp 31 is symmetrically provided with a boss 311 and a stopper 312. The top surface of the sliding card seat 32 is correspondingly provided with a second slideway 321 and a limiting boss 322. When the electric clamp boss 311 is inserted into the second slideway 321, the second electric clamp 31 can move left and right in the sliding card seat 32, and its movable position can avoid the interference of the battery pole ear, and the stroke is limited by the boss 322 and the stopper 312. A pin groove 324 and a long hole 326 are provided on the back of the sliding seat 32. An L-shaped pin 323 is placed in the pin groove 324 through a first spring 325, and its elbow portion is placed in the long hole 326. The sliding seat 32 can be adjusted in the upper and lower positions in the sliding groove 33 by moving the pin 323. When the height position of the second electric clamp 31 corresponding to the position of the pole ear is determined, the pin 323 enters the equidistant circular hole 332 under the action of the spring force. At this time, the sliding seat 32 is fixed, and the position of the other electric clamp is adjusted accordingly.

[0034] like Figure 8 and Figure 9 As shown, the partition clamping assembly 4 is composed of a partition 41, a movable top clamping block 42, a supporting block 43, a top block cover plate 44 and a second spring 45. The two movable top clamping blocks 42 are provided with spring mounting holes. When the movable top clamping block 42 and the second spring 45 are installed in the long strip hole of the partition 41, its movable stroke is limited by the top block cover plate 44. The lower end of the movable top clamping block 42 is fixedly connected to the supporting block 43 to ensure that the movable top clamping block 42 can be smoothly extended and retracted.

[0035] The partition clamping assembly 4 is installed in parallel on the tooling base plate 1, and the interval forms a lithium battery storage grid 12. When the soft-pack battery is placed sideways in the grid, because its thickness is larger than the floating gap between the top block and the partition, the battery is squeezed into the grid 12 along the upper end inclined surface of the movable top clamping block 42. At this time, the end face of the battery pole ear is close to the limit block 5, and the battery is pressed and positioned by the pressure of the second spring 45. When the battery is a single-sided double-pole ear, the height position of the two second electric clamps 31 of the electric clamp bracket assembly 3 is adjusted to clamp the positive and negative poles of the pole ear to complete the discharge; when the battery is a single-pole ear at both ends, the positive pole electric clamp position of the electric clamp bracket assembly 3 is adjusted to clamp this end pole ear, and the other end is adjusted according to the battery length and the height position of the pole ear. The distance of the first electric clamp 21 on the electric clamp sliding assembly 2 completes the connection between the discharge negative electrode and the pole ear. The loading tooling can adapt to soft-pack lithium batteries with different tab distribution patterns and different tab sizes, and can meet the mixed clamping and power connection of multiple soft-pack lithium batteries of various specifications.

[0036] The above-described embodiments merely represent specific implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
