FIG. 1 is a schematic view of a novel thermal lamination stack mechanism according to the present utility model.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.

Examples

Referring to fig. 1, the present embodiment provides a novel thermal lamination mechanism, which includes a conveying assembly 1, a driving roller set 2, a lamination table 3, a right pressing knife 4, a left pressing knife 5, a lamination table translation assembly 6 and a CCD camera assembly 7. The conveying assembly 1 and the driving roller group 2 are sequentially arranged along the conveying direction of the pole piece, the driving roller group 2 consists of an upper driving roller and a lower driving roller, a gap for the pole piece unit 10 to be spit is arranged between the upper driving roller and the lower driving roller, and the pole piece unit 10 is conveyed by the conveying assembly 1 and spit at a constant speed by the upper driving roller and the lower driving roller; the stacking table 3 is movably arranged on the stacking table translation assembly 6 and is positioned below the driving roller group 2, the stacking table translation assembly 6 comprises a screw rod, a motor and a speed reducer, and the stacking table can move along the screw rod through the driving of the motor and the speed reducer; a right pressing cutter 4 is movably arranged on the right end part of the stacking table 3, a left pressing cutter 5 is movably arranged on the left end part of the stacking table 3, and the right pressing cutter 4 and the left pressing cutter 5 realize the pressing and loosening of the pole piece unit 10 through up-and-down movement; the CCD camera assembly 7 is located above the limit position of the stacking translation assembly 6 and is used for alignment photographing detection.

Working principle: the pole piece unit 10 is discharged by the upper driving roller and the lower driving roller at constant speed, after the stacking platform 3 accelerates to the same speed as the speed of the sheet discharge of the driving roller, the right side of the pole piece unit 10 falls on the stacking platform 3 and is compressed by the right pressing cutter 4, the left pressing cutter 5 opens in advance, the right pressing cutter 4 compresses the rear stacking platform 3 to keep the right movement with the same sheet discharge speed of the driving roller, when the pole piece unit 10 is completely discharged and falls on the stacking platform 3, the left pressing cutter 5 immediately starts to compress, the stacking platform 3 reaches the right limit position after the compression is completed, the stacking platform 3 is stationary due to the response time of a motor, meanwhile, the upper CCD camera assembly 7 performs alignment photographing detection, and after the detection is qualified, the stacking platform 3 moves leftwards and returns to the splicing position again, and the actions are repeated.

Because lamination speed is fast, in order to adapt to different lamination speeds, the lead screw that the folding platform translation subassembly 6 used adopts the big lead screw of major diameter.

Through optimizing the motor point position for it can obtain faster lamination speed, under satisfying the operation requirement of lead screw, motor and reduction gear, lamination speed can equal to drive roller and tell the piece speed.

On the premise of high lamination, better lamination precision can be obtained by adjusting the angle of the driving roller for discharging the lamination and matching with the CCD camera component 7.

The foregoing description of the preferred embodiment of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
