Description

A reciprocating swing-type battery liquid filling and wiping device Technical Field

[0001] This invention relates to the field of battery production equipment technology, specifically to a reciprocating swing-type battery liquid injection and wiping device. Background Technology

[0002] In the lithium battery industry, battery manufacturing involves a series of processes including cell assembly, encapsulation, electrolyte injection, cleaning of electrolyte residue, and welding. After the electrolyte is injected into the battery through the injection port on the battery casing, some electrolyte remains on the battery surface. Traditional methods involve manually wiping with cleaning solution or cleaning by blowing air. However, manual cleaning is prone to secondary contamination, reduces yield, and has low efficiency. The blowing method can also cause corrosive electrolyte splashing. Patent application CN202210726807.8 proposes a casing-entry electrolyte wiping mechanism that uses non-woven fabric for automatic wiping instead of the traditional blowing method. However, since it does not use cleaning solution, wiping with only non-woven fabric cannot completely remove electrolyte residue. Summary of the Invention

The device is characterized by further including: a swing wiping mechanism connected to the base block; the drive mechanism drives the base block and the swing wiping mechanism to switch positions between the cleaning liquid container and the battery container; the swing wiping mechanism includes a telescopic cylinder hinged to the base block, a bending rod, and a quick-change wiping head; the bending rod includes a short rod section and a long rod section connected in a V-shape; the telescopic end of the telescopic cylinder is hinged to the end of the short rod section; the quick-change wiping head is connected to the end of the long rod section; the bending rod is rotatably connected to the base block at the junction of the short and long rod sections; the bending rod, as the telescopic cylinder extends and retracts, drives the quick-change wiping head to reciprocate and swing to wipe the battery surface.

[0008] Furthermore, the quick-change wiping head includes a sleeve slidably connected to a long rod section and a wiping block with a perforation at its upper end. The lower end of the long rod section is bent to both sides to form a baffle to restrict the sleeve from sliding down. A slot is formed at the lower end of the long rod section, and the long rod sections on both sides of the slot form thin plates that can be elastically bent. An external insertion hole is formed on the surface of the sleeve, and an internal insertion hole is formed at the lower end of the side of the long rod section. The wiping block is fixed in position by a rod that passes through the external insertion hole, the internal insertion hole, and the perforation in sequence.

[0009] Furthermore, the inner wall of the sleeve is provided with a protrusion, and the outer wall of the long rod section is provided with a groove extending along the length of the long rod section, and the protrusion and the groove are slidably connected.

[0010] Furthermore, the thin plate elastically opens to both sides and is interference-fitted with the sleeve.

[0011] Furthermore, the wiping block is a stack of dust-free paper or non-woven fabric.

[0012] Furthermore, a short shaft is fixedly connected to the surface at the junction of the short and long rod sections.

The connecting rod and the bending rod can rotate synchronously around the short shaft as the central axis.

[0013] Furthermore, the liquid-absorbing block is located at a greater distance from the battery compartment compared to the quick-change wiping head.

[0014] Furthermore, the lower surface of the liquid-absorbing block is provided with a square groove that matches the width of the upper surface of the battery.

[0015] Furthermore, the driving mechanism includes a transverse linear guide rail, a transverse moving block connected to the transverse linear guide rail, a longitudinal linear guide rail connected to the surface of the transverse moving block, and a longitudinal moving block connected to the surface of the longitudinal linear guide rail.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] A reciprocating swing-type battery electrolyte injection and wiping device, as shown in Figures 1-6, includes a drive mechanism 1, a base block 2, a battery material box 3, a cleaning fluid box 4, and a swing wiping mechanism 5. The battery material box 3 contains batteries arranged to be cleaned, and the cleaning fluid box 4 is open and contains cleaning fluid for cleaning the battery electrolyte.

[0030] The base block 2 is connected to the drive mechanism 1. Specifically, the drive mechanism 1 includes a transverse linear guide rail 11, a transverse moving block 12 connected to the transverse linear guide rail 11, a longitudinal linear guide rail 13 connected to the surface of the transverse moving block 12, and a longitudinal moving block 14 connected to the surface of the longitudinal linear guide rail 13. The base block 2 is fixedly connected to the lower end of the longitudinal moving block 14. The base block 2 is driven by the drive mechanism 1 and can change its position. The moving plane of the base block 2 is a vertical plane. A conveyor belt 6 is provided below the drive mechanism 1. The conveyor belt 6 is used to drive the battery box 3. The driving direction of the conveyor belt 6 is perpendicular to the moving plane of the base block 2, thereby facilitating automatic transmission and switching of the battery box 3 to be cleaned.

[0031] The swing wiping mechanism 5 is connected to the base block 2. The drive mechanism 1 drives the base block 2 and the swing wiping mechanism 5 to switch positions between the cleaning fluid box 4 and the battery box 3. When the swing wiping mechanism 5 is driven by the drive mechanism 1 to move to the cleaning fluid box 4, it completes the process of dipping in the cleaning fluid. When the swing wiping mechanism 5 is driven by the drive mechanism 1 to move above the battery box 3, it completes the wiping process.

[0032] Please refer to Figures 4-6. The swing wiping mechanism 5 includes a telescopic cylinder 51 hinged to the base block 2, a bending rod 52, and a quick-change wiping head 53. The telescopic cylinder 51 is a double-acting pneumatic cylinder or a hydraulic cylinder. The bending rod 52 includes a short rod section 52a and a long rod section 52b. The short rod section 52a and the long rod section 52b are bent and connected in a V-shape to form the bending rod 52. The telescopic end of the telescopic cylinder 51 is hinged to the end of the short rod section 52a. The quick-change wiping head 53 is connected to the end of the long rod section 52b. The bending rod 52 is rotatably connected to the base block 2 at the junction of the short rod section 52a and the long rod section 52b. When the telescopic cylinder 51 extends and retracts, the telescopic cylinder 51 drives the bending rod 52 to rotate back and forth, thereby causing the quick-change wiping head 53 to swing back and forth in an arc path and wipe the battery surface. This process is mechanically driven to drive manual wiping, which is quick, fast, and does not produce secondary pollution. In addition, when the telescopic cylinder 51 extends and retracts, it swings back and forth to wipe away the electrolyte residue at the filling port and edges of the battery surface. During the back and forth wiping, the residual electrolyte is wiped away with cleaning fluid from the opposite direction, resulting in thorough cleaning.

[0033] In this invention, the quick-change wiping head 53 includes a sleeve 53a and a wiping block 53b. Referring to Figure 7, the sleeve 53a is slidably connected to a long rod section 52b. The wiping block 53b is a stack of cleanroom paper or non-woven fabric in a block shape, and a perforation 53b1 is provided at the upper end of the wiping block 53b. A slot 52b2 is provided at the lower end of the long rod section 52b. The long rod sections 52b on both sides of the slot 52b2 form elastically bendable thin plates 52b3. The thin plates 52b3 elastically open to both sides and are press-fitted with the sleeve 53a. The wiping block 53b is inserted into the slot 52b2, and the sleeve 53a slides downwards to press the opened thin plates 52b3 against the wiping block 53b, ensuring the stability of the wiping block 53b.

[0034] An external insertion hole 53a1 is provided on the surface of the sleeve 53a, and an internal insertion hole 52b4 is provided at the lower end of the side of the long rod section 52b. When installing the wiping block 53b, the wiping block 53b is inserted into the slot 52b2, and the sleeve 53a is slid down until the internal insertion hole 52b4 and the external insertion hole 53a1 are coaxially aligned. The position of the wiping block 53b is fixed by the insertion rod 54 passing through the external insertion hole 53a1, the internal insertion hole 52b4 and the through hole 53b1 in sequence, so that the wiping block 53b can be replaced quickly.

[0035] In addition, baffles 52b1 are formed by bending the lower end of the long rod section 52b to both sides, and the baffles 52b1 limit the extreme position of the sleeve 53a sliding down.

[0036] A protrusion 53a2 is provided on the inner wall of the sleeve 53a, and a groove 52b5 extending along the length of the long rod section 52b is provided on the outer wall of the long rod section 52b. The protrusion 53a2 and the groove 52b5 are slidably connected. When the sleeve 53a slides outside the long rod section 52b, the protrusion 53a2 slides in the groove 52b5 and plays a guiding role.

[0037] As one embodiment of the present invention, this embodiment proposes a structure that can be linked with a reciprocating oscillating wiping head to further clean the battery surface that has been wiped with cleaning fluid. Specifically, a short shaft 55 is fixedly connected to the surface of the bending rod 52 at the turning point between the short rod section 52a and the long rod section 52b. A hole is opened on the surface of the base block 2, and the short shaft 55 passes through the hole on the surface of the base block 2, extending from the rear side to the front side of the base block 2. A connecting rod 56 is fixedly connected to the end of the short shaft 55, and a shaft 57 is fixedly connected to the end of the connecting rod 56. A base 58 is rotatably connected to the shaft 57, and a liquid-absorbing block 59 is connected below the base 58. A guide rod 510 is fixedly connected above the base 58. A bearing seat 7 is also fixedly connected to the base block 2, and a connecting shaft 511 is rotatably connected to the bearing seat 7. A limiting tube 512 is fixedly connected to the end of the connecting shaft 511, and the guide rod 510 passes through the limiting tube 512 and is slidably connected to the limiting tube 512. When the telescopic cylinder 51 pushes the bending rod 52 to rotate around the short axis 55, the connecting rod 56 can rotate synchronously around the short axis 55. The connecting rod 56 drives the base 58 and the liquid suction block 59 to swing. The guide rod 510 slides in the limiting tube 512. The limiting tube 512 and the connecting shaft 511 rotate. Therefore, the position of the liquid suction block 59 can be adjusted by controlling the telescopic cylinder 51, so that the liquid suction block 59 can be moved to a position flush with the upper surface of the battery, which is convenient for cleaning the cleaning fluid.

[0038] The lower surface of the liquid absorption block 59 is provided with a square groove 59a that matches the width of the upper end face of the battery. By controlling the extension and retraction of the telescopic cylinder 51, the liquid absorption block 59 can be moved to a position flush with the upper end face of the battery. The square groove 59a surrounds the battery from above, which can clean the upper end face and sides of the battery.

[0039] The bottom of the movable range of the liquid absorption block 59 and the wiping block 53b are flush, and the liquid absorption block 59 and the wiping block 53b are staggered to prevent interference between the liquid absorption block 59 and the wiping block 53b during the application of cleaning solution and the absorption of cleaning solution, respectively.

[0040] The absorbent block 59 is located further away from the battery compartment 3 than the quick-change wiping head 53. The quick-change wiping head 53 first picks up the cleaning fluid from the cleaning fluid tank 4. Then, the drive mechanism 1 drives the base block 2 to move, bringing the quick-change wiping head 53 above the battery compartment 3. Under the extension and retraction of the telescopic cylinder 51, the quick-change wiping head 53 swings back and forth, applying the cleaning fluid to the battery. After the quick-change wiping head 53 finishes applying the cleaning fluid, the drive mechanism 1 continues to drive the base block 2 to move and controls the extension and retraction of the telescopic cylinder 51, cleaning the electrolyte on the battery surface through the absorbent block 59. Throughout the cleaning process, the drive mechanism 1 drives the base block 2 to move in the same direction, sequentially cleaning through the quick-change wiping head 53 and the absorbent block 59, resulting in high speed and efficiency.

[0041] The invention first dips the cleaning solution into the substrate, as shown in Figure 1. The drive mechanism 1 moves the base block 2 above the cleaning solution box 4, the telescopic cylinder 51 extends, the long rod section 52b rotates downward, the longitudinal linear guide rail 13 moves the longitudinal moving block 14 downward, and the wiping block 53b extends into the cleaning solution box 4 to dip into the cleaning solution. Then, the cleaning solution is applied by reciprocating oscillation, as shown in Figure 2. The longitudinal linear guide rail 13 moves the longitudinal moving block 14 upward, and the transverse linear guide rail 11 moves the transverse moving block 12 upward above the battery box 3 until the wiping block 53b is above the battery box 3. The telescopic cylinder 51 extends and retracts, pushing and pulling the bending rod 52, causing the long rod section 52b to oscillate back and forth, positioned on the long rod. The wiping block 53b at the end of segment 52b applies cleaning fluid back and forth on the battery surface to dilute and clean residual electrolyte. Finally, the suction block 59 cleans the cleaning fluid. Specifically, the transverse linear guide 11 continues to drive the transverse moving block 12 until the suction block 59 is above the battery box 3. The extension and retraction of the telescopic cylinder 51 is controlled so that the suction block 59 is at a height that can adhere to the battery surface. The conveyor belt 6 is controlled to move the battery box 3 until the square groove 59a of the suction block 59 can surround the battery. The transverse linear guide 11 drives the transverse moving block 12 to move the suction block 59 from one side of the battery box 3 to the other side, cleaning the cleaning fluid. The above process is repeated, and the battery boxes 3 are conveyed sequentially by the conveyor belt 6 to achieve a streamlined cleaning operation. This invention, through the cooperation of the swing wiping mechanism 5 and the drive mechanism 1, can automatically realize the cleaning fluid dipping, cleaning fluid application and cleaning process in an integrated manner, so that the residual electrolyte on the battery surface can be thoroughly cleaned, ensuring the battery yield.
