Description

Technical Field

[0001] The invention relates to the technical field of new energy vehicle battery production, and in particular to a new energy vehicle battery nail pulling device. Background Art

[0002] In the production process of new energy vehicle batteries, especially in the battery packaging stage, glue nails are often used to seal the battery's injection holes. By fixing the glue nails to the injection holes of the battery shell through colloid, the battery interior can be isolated from the external environment, preventing electrolyte leakage or external impurities from entering the battery, thereby ensuring the safety and reliability of the battery.

[0003] In the manufacturing process of new energy vehicle batteries, cell formation is an important step. Its purpose is to form a stable oxide film on the surface of the battery cell through electrochemical reaction to improve the cycle life and safety performance of the battery. In this process, the inner side of the battery shell needs to fit tightly with the electrode to ensure the complete electrochemical reaction. The presence of glue nails on the battery shell may cause a small gap between the battery and the battery cell, thereby affecting the formation effect. Therefore, before the battery cell is formed, the glue nails need to be pulled out to ensure a high degree of fit on the surface of the battery cell and improve the formation effect. In the process of pulling out the glue nails, directly pulling out the glue nails with force through a driving device is usually a fast and direct method. However, in this method, during the process of pulling out the nails, due to the direct high-intensity tensile force on the glue nails during the pulling process, the glue nails will be damaged and the injection hole on the battery shell will be deformed. While it is not convenient for the glue nails to be used sustainably, the deformation of the injection hole affects the subsequent sealing operation of the new energy vehicle battery. For this reason, we propose a new energy vehicle battery nail pulling device. Summary of the invention

[0042] Preferably, the vibration component includes an L-shaped plate 1401 arranged below the lifting platform 5, a second telescopic component for telescopically connecting the L-shaped plate 1401 is arranged between the L-shaped plate 1401 and the lifting platform 5, and the lower end of the L-shaped plate 1401 is located below the annular plate 9 in the initial state, and a plurality of groups of push plates 1402 are fixed to one side of the L-shaped plate 1401, and the upper and lower sides of each group of push plates 1402 are provided with a first inclined surface 1403 for abutting against the end of the transmission rod 1201 for transmission; during the descent of the lifting platform 5, the annular plate 9 and the L-shaped plate 1401 are driven to move downward by the connection of the fixed rod 8 and the connection of the second telescopic component, Because the lower end of the L-shaped plate 1401 is below the annular plate 9 in the initial state, as the lifting platform 5 moves downward, the lower end of the L-shaped plate 1401 first abuts against and limits the upper end of the shell 201, and as the lifting platform 5 and the annular plate 9 continue to move, one end of the transmission rod 1201 on the annular plate 9 successively abuts against the first inclined surface 1403 on each group of push plates 1402, and through the abutting transmission effect of the first inclined surface 1403 and one end of the transmission rod 1201 and the telescopic resetting effect of the first telescopic component on the strip plate 1001, the transmission rod 1201 and the strip plate 1001 synchronously reciprocate in the horizontal direction as they move downward in the vertical direction.

[0044] Preferably, the positioning component includes a placement groove 301 for placing the new energy vehicle battery, which is opened on the carrier 103.

A third telescopic component for telescopically connecting the extrusion plates 302 is arranged inside the placement groove 301. The upper end of each group of extrusion plates 302 is provided with a second inclined surface 303 for abutting and transmitting with the lower end of the new energy vehicle battery. The new energy vehicle batteries to be processed are placed in each placement groove 301 of the carrier 103 in turn. During the placement process, the lower end of the shell 201 abuts against the second inclined surface 303 on each group of extrusion plates 302 inside the placement groove 301, pushing each group of extrusion plates 302 to undergo a contraction movement under force. After the shell 201 is placed, each group of third telescopic components pushes each group of extrusion plates 302 against each other, so that one side of each group of extrusion plates 302 abuts against the four sides of the shell 201 respectively. Through the abutting and squeezing effect, the shell 201 is positioned and placed on the placement groove 301 of the supporting platform 103, which is convenient for subsequent more accurate nail removal operations.

[0045] Preferably, the third telescopic component includes multiple groups of second sleeves 401 fixed inside the placement groove 301, and the second sleeves 401 are slidably connected with the second slide rod 402, one end of the second slide rod 402 is fixed to one side of the extrusion plate 302, and the outer side of each group of second sleeves 401 is sleeved with a fourth spring 403; through the multiple groups of second sleeves 401 and the second slide rod 402, the telescopic guiding movement of the extrusion plate 302 after being subjected to force is facilitated, and through the multiple groups of fourth springs 403, the reset movement of the extrusion plate 302 after contraction is facilitated.

[0047] In this scheme: A new energy vehicle battery nail removal device includes the following steps:

[0048] In the process of using the nail pulling equipment to pull out the nails 202 on the new energy vehicle battery, the new energy vehicle battery to be processed is placed on each placement groove 301 of the carrier 103 in turn. During the placement process, the lower end of the shell 201 is against the second inclined surface 303 on each group of extrusion plates 302 inside the placement groove 301, pushing each group of extrusion plates 302 to undergo a contraction movement under force. After the shell 201 is placed, each group of third telescopic components pushes each group of extrusion plates 302 against each other, so that one side of each group of extrusion plates 302 is against the four sides of the shell 201 respectively. Through the mutual extrusion effect, the shell 201 is positioned and placed on the placement groove 301 of the carrier 103, so as to facilitate the subsequent more accurate nail removal operation.

[0049] After positioning and placing the shells 201 of each group of new energy vehicle batteries on each group of placement grooves 301 of the carrier 103, the carrier 103 is pushed into the interior of the operating room 102 by the first cylinder 105. After the pushing is completed, the lifting platform 5 is driven to move downward by the second cylinder 6. During the downward movement of the lifting platform 5, the lower ends of the third T-shaped rods 701 of each group are driven to abut against the upper ends of the shells 201. As the lifting platform 5 continues to move downward, the fifth spring 703 is deformed by force to generate elastic force. The elastic force of the fifth spring 703 causes the lower end of each group of third T-shaped rods 701 to squeeze the shell 201. The squeezing effect on the shell 201 facilitates the separation of the rubber nails 202 from the shell 201 during the nail removal process. In the process of the lifting platform 5 descending, the connecting effect of the fixed rod 8 and the connecting effect of the second telescopic assembly drive the annular plate 9 and the L-shaped plate 1401 to move downward. Because the lower end of the L-shaped plate 1401 is below the annular plate 9 in the initial state, as the lifting platform 5 descends, the L-shaped plate 1401 is moved downward. The lower end of the plate 1401 first abuts against the upper end of the shell 201 and limits the position. As the lifting platform 5 and the annular plate 9 continue to move, one end of the transmission rod 1201 on the annular plate 9 abuts against the first inclined surface 1403 on each group of push plates 1402 in turn. Through the abutting transmission effect of the first inclined surface 1403 and one end of the transmission rod 1201 and the telescopic reset effect of the first telescopic component on the strip plate 1001, the transmission rod 1201 and the strip plate 1001 are synchronously reciprocated in the horizontal direction as they descend in the vertical direction. During the movement of the strip plate 1001, the connection of the fixing pin 1002 drives the L-shaped clamping plate 1003 to move synchronously, and the L-shaped clamping plate 1003 performs a lateral reciprocating motion while descending, so that the L-shaped clamping plate 1003 performs a reciprocating knocking vibration from top to bottom on the outer side of the glue nail 202. By reciprocatingly knocking and vibrating the outer side of the glue nail 202 from top to bottom, a gap is formed between the glued glue nail 202 and the injection hole on the shell 201, or even directly separated, so as to facilitate the subsequent nail removal operation of the glue nail 202;

[0050] After the annular plate 9 is driven to descend, the lifting assembly drives the collar 1205 to move upward on the outer side of the annular plate 9. During the movement of the collar 1205, the support frame 1206 and the transmission pin 1204 are driven to move synchronously. During the movement of the transmission pin 1204, the interaction between the transmission pin 1204 and the inclined groove 1203 drives the transmission rod 1201 to contract under force. During the movement of the transmission rod 1201, the connection and transmission action of the strip plate 1001 and the fixing pin 1002 drives the L-shaped splint 1003 to press against the outer side of the rubber nail 202. At this time, the annular plate 9 is driven to rise. During the rising movement, the rubber nail 202 is pulled out from the liquid outlet of the shell 201 through the pressing action of each group of L-shaped splints 1003 against the surrounding of the rubber nail 202, thereby completing the nail pulling operation of the rubber nail 202.
