When the external force applied to the floating plate 41 is removed, the elastic element rebounds to recover the state before the elastic deformation, and then the floating plate 41 is driven to bounce.

The floating plate of this embodiment can kick-back and come-up along with elastic element, and when the coating machine carried out the rubberizing to electric core on the floating plate, can push down at the coating machine's rubberizing head and the combined action of floating plate come-up under, certain pretightning force when guaranteeing that the double faced adhesive tape can closely laminate on electric core for the double faced adhesive tape laminating, has improved the laminating efficiency and the laminating quality of double faced adhesive tape.

The external force acting on the floating plate 41 may be a common force of a pressing force of the bonding head 71 pressing the floating plate 41 and a pulling force of the prepressing mechanism 44 pulling the floating plate 41. When the surface of the battery cell on the floating plate 41 is pasted with glue, the pasting head 71 of the pasting machine 7 moves to the upper side of the floating plate 41, then moves downwards to press and hold the floating plate 41, and drives the pre-pressing mechanism 44 to pull the floating plate 41 downwards, so that the floating plate 41 moves towards the mounting plate 42, the elastic element between the floating plate 41 and the mounting plate 42 is further compressed to generate elastic deformation, and after the elastic element recovers the state before deformation, the floating plate 41 is driven to bounce upwards to provide a certain pre-tightening force for the double-sided adhesive tape. Due to the dual functions of the pressure of the adhesive tape head and the pushing force of the prepressing mechanism during adhesive tape pasting, the elastic element can generate larger elastic deformation, the adhesion of the double-sided adhesive tape on the surface of the battery cell can be ensured to be tighter, and the adhesion efficiency and the adhesion quality of the double-sided adhesive tape are further improved.

As shown in fig. 23 and 24, the winding device 73 includes a driving mechanism 731, a friction assembly 732, and a winding roller 733, the driving mechanism 731 is in power connection with the winding roller 733 through the friction assembly 732, the driving mechanism 731 drives the friction assembly 732 to generate a friction force, and the winding roller 733 performs a winding operation under the friction force.

This embodiment drives the unreeling roller through friction pack is indirect and unreels, can restrict the rolling speed of wind-up roll, avoids advancing the problem that the in-process tension is too big and tear because of the sticky tape.

Under the action of the friction force generated by the friction component, the driving mechanism 731 and the winding roller 733 can keep synchronous rotation, so that the phenomenon that the winding roller is excessively rotated due to inertia to cause the phenomenon that the adhesive tape is torn due to overlarge tension is avoided.

When the resistance applied to the winding roller 713 is smaller than the friction force generated by the friction assembly 732, the power sheet 7321 drives the driving sheet 7322 to rotate, so as to provide winding power to the winding roller 733 for winding operation; when the resistance force applied to the winding roller 733 is greater than the friction force generated by the friction assembly 732, the power sheet 7321 cannot drive the driving sheet 7322 to rotate, so that the winding power is stopped being supplied to the winding roller 733, and the phenomenon that the tension force of the adhesive tape is too large due to the over-rotation of the winding roller is avoided.

When the rotating speed of the winding roller 733 is greater than a predetermined rotating speed, the resistance force applied to the winding roller 733 is greater than the friction force generated by the friction assembly 732. That is to say, the rotating speed of the wind-up roller 733 is far greater than that of the wind-up roller 713, and when the wind-up roller 733 is over-rotated, the friction component 732 does not provide power to the wind-up roller 733 any more, and the rotating speed of the wind-up roller 733 is gradually reduced to match the rotating speed of the wind-up roller 713, so that the excessive tension of the adhesive tape is avoided.

The detection device 734 is disposed above the wind-up roll 733, and detects whether the wind-up roll 733 is full according to the height of the wind-up on the wind-up roll 733. For example, when the detecting device detects that the winding height reaches the full-winding height, it is determined that the adhesive tape wound on the winding roller 733 is full-wound, and the winding operation may be stopped; when the detection device detects that the winding height is smaller than the full-winding height, it is determined that the wound adhesive tape on the winding roller 733 is not fully wound.

The stopper 735 may be provided between the driving piece 7323 and the winding roller 733, and may stop the winding roller 733 by abutting against the driving piece 7323.
