Embodiment 1

[0027] Such as figure 1 , figure 2 , image 3 , Figure 4As shown, the conveying mechanism of the cell coating machine that suppresses the bubbles in the coating is set on the frame 1 of the cell coating machine. Roller group, a film roll shaft 5, three film-drawing rollers 22 and a film cutter 23, the film-applying roller group includes a pair of vertically arranged and parallel film-applying rollers 2, and the film-applying roller 2 is made of polyurethane with a Shore hardness of 20° , between the two laminating rollers 2, there is a return tension spring 23, the free end of the PET film 6 on the roll film shaft 5 is clamped on the lifting film clamping finger 7, and the unfolded PET film 6 moves from the positioning platform 4 and the Passes between sets of film rolls. The front end of the cell coating machine inputs the 24 workpieces of the cell that have been plastic-sealed with aluminum-plastic film through the cell conveyor belt. The conveying mechanism of the ce...

Embodiment 2

[0036] The movable splint driving device 10 is an electric cylinder. Film sticking roller 2 selects the rubber that Shore hardness is 20 ° for use. All the other are with embodiment 1.

Embodiment 3

[0038] Film sticking roller 2 selects the rubber that Shore hardness is 22 ° for use. All the other are with embodiment 1.

Abstract

The invention discloses a battery cell coating machine conveying mechanism capable of inhibiting coating bubbles. The mechanism is arranged on a rack of a battery cell coating machine, and a film pasting roller set is arranged on the rack and comprises a pair of film pasting rollers which are arranged up and down in parallel. The mechanism comprises a battery cell transferring mechanical arm, andthe battery cell transferring mechanical arm is connected to the rack in a sliding mode, wherein a clamping type battery cell clamp is arranged on the battery cell transferring mechanical arm. The invention further discloses a battery cell coating method applying the mechanism. According to the invention, the structural design is optimized according to the cause of the battery cell coating bubbles, can eliminate the bulging factors of an aluminum-plastic film, guarantees that the surface flatness of the aluminum-plastic film is not damaged or is damaged as little as possible when a battery cell is transferred, so that bubbles are inhibited in the subsequent PET film pasting process; moreover, the bubbles are further eliminated or reduced by controlling the hardness of a rubber sheet of thefilm pasting rollers.

Description

technical field [0001] The invention relates to an auxiliary working mechanism of battery processing equipment and a related working method, more specifically, it relates to a conveying mechanism of a cell coating machine and a cell coating method for suppressing coating bubbles. Background technique [0002] At present, during the assembly process of lithium battery cells, it is necessary to weld the tabs, apply high-temperature brown glue to the tabs, insulate the tabs and fix the position of the tabs, and then pack the cells with aluminum-plastic film. If there are scratches and the barcode is not clear, it is necessary to apply a PET film with good high and low temperature resistance and mechanical properties and high transparency to the surface of the battery cell. At present, the PET film application of the battery cell is usually completed by the battery wrapping machine. The existing battery wrapping machine generally uses a suction cup to grab the aluminum-plastic f...
