The present invention relates to the field of lithium-battery producing devices, and in particular to, an automatic gluing apparatus for a fixed shaft-type rewinding reel.
The electrode plate is one of the key components in lithium batteries. Currently, the production process of the electrode plate includes coating, rolling, and slitting of the electrode plate. The electrode plate is mainly cut by a slitting machine to form material strips of a specific width. For convenience in use and transportation, the slit electrode plates typically need to be wound into rolls on a rewinding reel.
Before rewound, the electrode plate requires manual gluing operation on the surface of the reel. Specifically, a worker sticks a double-sided tape or yellow glue onto the surface of the empty reel, and the electrode plate is fixed to the reel via the double-sided tape or yellow glue, and then wound. However, the manual gluing operation has low efficiency, which affects the production efficiency of the electrode plates.
An objective of the present invention is to provide an automatic gluing apparatus for a fixed shaft-type rewinding reel. After a glue supply mechanism supplies a glue to a gluing mechanism, the gluing mechanism automatically applies the glue to the surface of the rewinding reel. This gluing mechanism can resolve the inconvenience of the manual gluing operation, improve the efficiency of electrode plate rewinding, and address the problem that the low efficiency of the manual gluing operation affects the production efficiency of the electrode plate.
The automatic gluing apparatus for a fixed shaft-type rewinding reel in the present invention includes:
Further, in a preferable embodiment, the glue scraping head further includes:
In a preferable embodiment, the glue-scraping drive assembly includes:
Further, in a preferable embodiment, a side of the transition frame is provided with a bottom plate, the bottom plate is provided with a roller, the roller is detachably connected to the bottom plate, and when the gluing mechanism applies the glue, the roller rolls on a surface of the rewinding reel.
Further, in a preferable embodiment, a side of the adjustment seat is provided with a drying assembly configured to accelerate drying of the liquid glue.
Furthermore, in a preferable embodiment, the drying assembly includes an air nozzle, the air nozzle is disposed on a side of the adjustment seat, an air inlet end of the air nozzle is provided with a hot air pipe, and the hot air pipe communicates with the air nozzle.
In a preferable embodiment, the glue supply mechanism includes:
In a preferable embodiment, a side of the gluing mechanism is provided with a frame, the frame is provided with a cleaning assembly, and a moving assembly that is configured to drive the gluing mechanism to approach or leave the cleaning assembly is disposed between the frame and the gluing mechanism.
Further, in a preferable embodiment, the cleaning assembly includes:
Furthermore, in a preferable embodiment, one side of the cleaning box is provided with an unwinding roller configured to unwind the cleaning cloth, the other side is provided with a rewinding roller configured to rewind the cleaning cloth, and the rewinding roller is in transmissive connection with a rewinding drive member configured to drive the rewinding roller to rotate.
Compared with the prior art, the present invention has the following advantages and beneficial effects:
In the present invention, according to the automatic gluing apparatus for a fixed shaft-type rewinding reel, the rewinding reel to be glued moves to a side of the gluing mechanism. The glue-scraping drive assembly drives the glue scraping head to approach the rewinding reel, and the glue supply mechanism supplies the glue to the glue scraping head. As the rewinding reel moves, the glue scraping surface of the glue scraping head adheres to the outer surface of the rewinding reel, such that the liquid glue is evenly scraped onto the surface of the rewinding reel. The gluing mechanism thus achieves automatic gluing on the rewinding reel. The cooperation between the gluing mechanism and the glue supply mechanism addresses the low efficiency of the existing manual gluing operation, thereby improving the production efficiency of the electrode plates.

A side of the glue storage tank 31 is provided with a glue supply valve 32. The glue supply valve 32 communicates with the glue storage tank 31 and is mounted on the mounting plate 11. A glue supply pipe 321 is disposed between the glue supply valve 32 and the glue scraping seat 162. The glue scraping seat 162 communicates with the glue supply pipe 321 at the glue flow hole 1621. When the gluing mechanism 1 applies the glue, the glue extruding member 311 extrudes the liquid glue in the glue storage tank 31. After the glue supply valve 32 is opened, the glue liquid flows sequentially through the glue supply valve 32 and the glue supply pipe 321, and then flows out of the glue outlet 164 through the glue flow hole 1621 to the surface of the rewinding reel 8.
In some specific embodiments shown, a side of the glue storage tank 31 is provided with a primary glue supply module. The primary glue supply module includes a glue supply pump, a pressure transmitter, a pressure relief valve, and a check valve arranged sequentially along the flow direction of the liquid glue. The glue supply pump is preferably but not limited to a platen screw pump. The platen screw pump fills the glue storage tank 31 with a glue. The pressure transmitter and the pressure relief valve can adjust the pressure during the delivery process of the liquid glue, so as to reduce an overpressure situation caused by blockage or improper operation. The check valve can reduce the situation where the liquid glue flows back to the glue supply pump during the delivery process after the glue extruding member 311 quickly extrudes the glue, ensuring the smooth delivery of the liquid glue and improving the uniformity and stability of the glue supply of the glue supply mechanism 3.
When the gluing mechanism 1 applies the glue, the rewinding reel 8 is glued at the bottom of the gluing mechanism 1. Referring to
The arrangement of the first elastic member 131, the second elastic member 141, and the third elastic member 151 can effectively offset the impact caused by the angle or center distance deviation between the rewinding reel 8 and the glue scraping head 16 when the rewinding reel 8 comes into contact with the glue scraping head 16, providing a certain degree of protection for the glue scraping head 16. When the rewinding reel 8 fits with the glue scraping head 16, the offset between the center of the rewinding reel 8 and the center of the glue scraping head 16 causes the adjustment seat 13 to rotate laterally. The adjustment seat 13 is rotationally connected to the connecting plate 12, which can effectively eliminate the lateral rotation, allowing for multiple degrees of freedom of the gluing mechanism 1, so as to adapt to a gluing operation at a different angle.

Further, a positioning plate 211 is arranged between the air nozzle 21 and the bracket 22. The positioning plate 211 is connected to the air nozzle 21, and the side of the positioning plate 211 close to the bracket 22 is provided with a positioning waist-shaped hole 212. The positioning plate 211 can be assembled with the bracket 22 by bolts at the positioning waist-shaped hole 212. The connection position of the air nozzle 21 with the bracket 22 is adjusted via the positioning plate 211, so as to adapt to the rewinding reel 8 with a different specification.
When the drying assembly 2 operates, the air compressing heater generates hot air, and the hot air flows through the hot air pipe 23 to the air nozzle 21 and is blown onto the surface of the rewinding reel 8 by the air nozzle 21. The hot air accelerates the drying of the liquid glue applied to the rewinding reel 8, thereby improving the gluing efficiency of the rewinding reel 8. In this case, the production efficiency of the electrode plate is further improved.

The rewinding reel 8 continues to move, and the glue scraping head 16 scrapes and applies the liquid glue on the surface of the rewinding reel 8. When the optical fiber sensor 6 detects the second groove 82, the glue-scraping drive member 121 drives the glue scraping head 16 to rise and leave the rewinding reel 8. The glue supply valve 32 closes, and the glue supply mechanism 3 stops supplying glue to the glue scraping head 16. The moving assembly 41 drives the gluing mechanism 1 to move above the cleaning assembly 5. The glue-scraping drive member 121 drives the glue scraping head 16 to descend and fit with the cleaning cloth 531. The cleaning assembly 5 cleans the residual liquid glue on the glue scraping head 16, and the rewinding drive member 58 rewinds the used cleaning cloth 531 onto the rewinding roller 57.
A side of the adjustment seat 13 is provided with a color mark sensor 7. Specifically, there are two color mark sensors 7, and the two color mark sensors 7 respectively correspond the two glue scraping heads 16. During the glue scraping process of the glue scraping head 16, the color mark sensors 7 detect whether the glue strip scraped by the glue scraping head 16 is complete to determine if there is any discontinuity.
