The lamination mechanism for inserting and coating the diaphragm is shown in figures 1a to 3 and comprises a lamination assembly 1, a diaphragm inserting and coating assembly 2 and a blanking assembly 3, so that the efficient lamination production of a pole piece battery core can be realized.
The lamination assembly 1 comprises a lamination table 101 as a main lamination station, and positive and negative pole pieces are alternately laminated and a diaphragm is coated on the lamination table 101 when pole pieces and cells are laminated.
Specifically, the lamination table 101 is a stacking platform, and a first diaphragm pressing claw 102 is arranged on the outer side of the lamination table 101; optionally, the first diaphragm pressing claw 102 is an air cylinder pressing claw, and the pressing claw is driven by an air cylinder to move downwards to perform lamination pressing on the pole piece electric core on the lamination table 101. Further, the first diaphragm pressing claw 102 is slidably disposed outside the lamination table 101, and the first diaphragm pressing claw 102 is movable in the width direction of the diaphragm to above the lamination table 101, that is, from the width direction of the diaphragm to above the lamination table 101, so that the alternately stacked pole pieces and diaphragms can be pressed from the front-back direction of the lamination table 101 when lamination is performed. In the specific embodiment shown, the first diaphragm pressing claws 102 include at least four first diaphragm pressing claws 102 distributed around the lamination table 101, and the at least four first diaphragm pressing claws 102 can be moved toward or away from the lamination table 101 in a linked manner.

Therefore, the diaphragm can be pasted on the last pole piece of the pole piece electric core, the auxiliary time between the stacking procedures of the two pole piece electric cores is greatly shortened, the working condition efficiency of the lamination device is exerted to the maximum extent, and the production efficiency is further improved.
Specifically, the membrane penetration coating assembly 2 includes a cell pallet 201 and an adsorption pallet 202. The battery cell pallet 201 and the adsorption supporting plate 202 are located between the position of the blanking assembly 3 far away from the lamination table 101 and the position of the lamination table 101, and both the battery cell pallet 201 and the adsorption supporting plate 202 are located below the blanking clamping jaw 301; the adsorption supporting plate 202 is located at one side close to the lamination table 101, the battery cell supporting table 201 is located at one side far away from the lamination table 101, and the adsorption supporting plate 202 can be moved to the position above the battery cell supporting table 201 at the side close to the lamination table of the battery cell supporting table 201.
And a diaphragm cutter assembly 4 is correspondingly arranged at the joint of the adsorption supporting plate 202 and the lamination table 101, specifically, the diaphragm cutter assembly 4 comprises a diaphragm cutter 401. The diaphragm cutter 401 arranged at the joint of the adsorption supporting plate 202 and the lamination table 101 can cut off the diaphragm stretching across the adsorption supporting plate 202 and the lamination table 101 so as to perform lamination coating of the next pole piece battery cell.
Preferably, referring to fig. 1a to fig. 3 again, the adsorption pallet 202 is specifically located above the cell pallet 201, and the adsorption pallet 202 is slidably disposed on the linear guide 204 and is movable to be located above the cell pallet 201 by the pushing cylinder 203.
The adsorption plate 202 is mounted on the linear guide 204 via a bracket, a head lifting cylinder 205 is mounted on the bracket, and the adsorption plate 202 is vertically movable by the lifting cylinder 205. When the diaphragm stretches across the adsorption supporting plate 202, the lifting cylinder 205 drives the adsorption supporting plate 202 to lift upwards, so that the adsorption supporting plate 202 is convenient to approach the diaphragm and adsorb and fix the diaphragm.
In a preferred embodiment, the suction tray 202 is provided with a vacuum suction hole 2021. Optionally, the vacuum absorption hole 2021 is communicated with a vacuum extractor, and can generate a vacuum absorption effect when the vacuum extractor works.
In addition, as shown in fig. 4, the side of the suction pallet 202 facing the blanking assembly 3 has a circular arc transition end 2020. When the diaphragm turns over a transition from adsorbing layer board 202 towards one side of unloading subassembly 3, circular arc transition tip 2020 and the diaphragm that turns over a roll over carry out direct contact, can avoid causing the damage to the diaphragm, effectively ensure the quality of pole piece electricity core.
Further, referring to fig. 1a to fig. 3 again, the adsorption supporting plate 202 and the cell supporting platform 201 are both provided with a clamping jaw avoiding groove, specifically, the clamping jaw avoiding groove includes a first clamping jaw avoiding groove 2011 on the cell supporting platform 201 and a second clamping jaw avoiding groove 2022 on the adsorption supporting plate 202. Moreover, as shown in fig. 5a and 5b, when the adsorption supporting plate 202 moves above the cell supporting platform 201, the second jaw avoiding groove 2022 on the adsorption supporting plate 202 corresponds to the first jaw avoiding groove 2011 on the cell supporting platform 201, and corresponds to the blanking jaw 301.
Thus, after the last pole piece of the pole piece cell is stacked on the lamination table 101, the pole piece cell can be clamped and transferred to a position far away from the lamination table 101 by the blanking clamping jaw 301, and the diaphragm is stretched; then, the suction plate 202 is lifted up by the lift cylinder 205 and approaches the stretched diaphragm. At this time, the vacuum extractor works, the vacuum adsorption hole 2021 of the adsorption supporting plate 202 adsorbs and fixes the diaphragm, and the diaphragm is cut off from the position where the adsorption supporting plate 202 is joined with the lamination table 101; unloading clamping jaw 301 shifts down the pole piece electric core and places on electric core saddle 201, and lift cylinder 205 orders about in step that absorption layer board 202 descends and drives the tensile diaphragm that cuts off and descend. Then, the adsorption supporting plate 202 is driven by the propulsion cylinder 203 to move to the direction close to the blanking assembly 3 along the linear guide rail 204 to the position above the cell supporting table 201, and in the moving process, the cut stretching diaphragm is turned over for 180 degrees along the arc transition end 2020 of the adsorption supporting plate 202 and is coated on the surface of the last pole piece of the pole piece cell, so that complete cell lamination is completed; meanwhile, after the diaphragm is cut off, the diaphragm tiled on the lamination table 101 can be positioned and compressed by the first diaphragm pressing claw 102 on the outer side of the lamination table 101, the next set of positive and negative pole pieces are alternately fed onto the lamination table 101 by the feeding mechanism, and the lamination table 101 starts to move left and right in a reciprocating manner to perform lamination of the next pole piece battery cell.

Specifically, the second diaphragm pressing claw 206 is a cylinder pressing claw, an initial position of the pressing claw is located outside the cell pallet 201, and the second diaphragm pressing claw is driven by a cylinder to rotatably extend above the cell pallet 201 and downwardly press the pole piece cell on the cell pallet 201 during operation.
After the pole piece electric core is clamped and transferred onto the electric core supporting platform 201 by the blanking clamping jaw 301, the pressing jaw of the second diaphragm pressing jaw 206 is driven by the cylinder to rotate to the position above the fixed supporting plate 201, the pressing jaw of the second diaphragm pressing jaw 205 is driven by the cylinder to press down the pole piece electric core again to prevent unwinding, and when the diaphragm to be cut off is coated on the surface of the last pole piece of the pole piece electric core, the pressing jaw of the second diaphragm pressing jaw 206 is driven by the cylinder to ascend and loosen, so that the pole piece electric core is pressed and rotates to return to an initial station.
