A pole piece die cut unreeling and taping mechanism according to an embodiment of the present utility model is described below with reference to fig. 1-5.

As shown in fig. 1-5, the pole piece die cutting, unreeling and taping mechanism mainly comprises a rubberizing mechanism 100, a waste material winding mechanism 200 and a cutting mechanism 300, wherein the waste material winding mechanism 200 is used for winding a material belt, the cutting mechanism 300 is used for cutting the material belt, and the rubberizing mechanism 100 is used for adsorbing and fixing the material belt and enabling a worker to carry out glue preparation operation on the pole piece.

Specifically, the two rubberizing mechanisms 100 are included, and the two rubberizing mechanisms 100 are disposed opposite to each other, i.e. the two mechanisms are symmetrically distributed. Each set of rubberizing mechanisms 100 includes an upper suction plate 110, a rubberizing plate 120, and a lower suction plate 130, the rubberizing plate 120 being located between the upper suction plate 110 and the lower suction plate 130. In the present embodiment, the upper suction plate 110, the rubberizing plate 120 and the lower suction plate 130 are sequentially arranged from top to bottom on one side of the rubberizing mechanism 100, the direction is the Y-axis direction, and the opposite direction of the two rubberizing mechanisms 100 is the X-axis direction. The gap between the plate surfaces of the two rubberizing mechanisms 100 is not more than 50mm, that is, the interval between the two rubberizing mechanisms 100 in the X-axis direction is not more than 50mm. The gap in the prior art is typically 300mm, because a certain operation space needs to be reserved for the glue preparation operation of the staff, the gap between the two glue applying mechanisms 100 is large, and the structure occupies a large space, so that the volume of the equipment is increased, and the manufacturing cost is increased due to the increase of the volume. The gap of the rubberizing mechanism 100 is not more than 50mm, so that the space is reduced, the equipment volume is reduced, and the manufacturing cost is reduced. The rubberizing plate 120 slides along one side of the rubberizing mechanism 100, and the sliding direction of the rubberizing plate 120 is the Z-axis direction. The rubberizing plate 120 sliding along the Z-axis direction can slide to the outside from the gap between the two rubberizing mechanisms 100, so as to facilitate the staff to prepare the rubberizing plate 120. When the rubberizing plate 120 sideslips to the outside of the rubberizing mechanism 100, the operation space of the staff is increased, the rubberizing mechanism is not limited by a gap of 50mm, the rubberizing operation is more convenient, the hands of the staff do not need to extend between the gaps of the mechanism, the rubberizing mechanism is safer, and the potential safety hazard is reduced.

The waste material winding mechanism 200 is arranged above the rubberizing mechanism 100, and utilizes the vertical deep space to enable equipment to be distributed along the vertical direction, so that the occupied space of the equipment is reduced. Specifically, the waste material winding mechanism 200 includes a winding shaft 220, and the material strip of the waste material winding mechanism 200 passes through the plate surface between the two rubberizing mechanisms 100 and is wound at the winding shaft 220.

The cutting mechanism 300 is disposed at one side of the rubberizing mechanism 100, and the cutting mechanism 300 is used for cutting the material tape between the two rubberizing mechanisms 100. When the material tape needs to be cut, the cutting mechanism 300 moves along the Z-axis direction to cut and reset the material tape.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the rubberizing plate 120 is slidably coupled to the rubberizing mechanism 100 by any one of a servo rail drive, a hydraulic drive, or a pneumatic drive. Specifically, the adhesive sheet 120 is moved in the Z-axis direction by any one of the above-described moving mechanisms. Whereas the prior art rubberizing mechanism 100 is only capable of moving in the X-axis direction, providing a location for personnel to prepare the glue by increasing the gap between the two rubberizing mechanisms 100. The utility model adopts the structure of Z-axis sideslip to increase the glue preparation space of the staff, has more convenient operation and higher safety coefficient, and reduces the potential safety hazard. The above-mentioned moving structures are all familiar to those skilled in the art, and will not be described in detail in the present embodiment. The servo guide rail is driven by sliding the slide seat and the slide rail to connect the glue pasting plate 120 with the slide seat, and the glue pasting plate 120 is driven to move laterally by the movement of the slide seat on the slide rail. While both hydraulic and pneumatic drives drive the side shift of the glue plate 120 in fluid driven fashion.

It should be appreciated that the implementation of Z-axis movement of the glue board 120 by servo rail drive, hydraulic drive, or pneumatic drive is not the only implementation. The structure of the movement of the rubberizing plate 120 along the Z-axis direction is not described in detail, and it should be understood that the flexible transformation of the structure of the rubberizing plate 120 along the Z-axis direction is considered to be within the scope of the present utility model.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the rubberizing plate 120 extends completely out of one side of the rubberizing mechanism 100. Specifically, in order to facilitate the preparation of the adhesive for the staff, the adhesive plate 120 moves along the Z-axis direction and is completely exposed at one side of the adhesive mechanism 100, and at this time, all the area of the adhesive plate 120 is located at one side of the adhesive mechanism 100, so that the staff can operate conveniently. When the worker completes the glue preparation step, the glue board 120 is retracted into the glue mechanism 100, so that the worker does not need to stretch into the device during the whole process, and the operation is safer. The rubberizing board 120 moves out towards the Z axis direction, the rubberizing mechanism 100 is manually provided with rubberizing on the rubberizing board 120, and then the rubberizing board is pushed back to the original position towards the Z axis, so that potential safety hazards caused by the fact that staff stretches hands to the interior rubberizing can be avoided, the safety coefficient is higher, and the operation is easier.
