The first driving member 311 is used for providing power to drive the rotating bracket 312 to rotate, so that the positions of the two rubberizing units 32 mounted on the rotating bracket 312 are changed, and when one of the two rubberizing units 32 is located at the glue taking position, the other one is located at the glue applying position. The first driving member 311 may be a motor, and the rotating bracket 312 is driven by the motor to rotate, so that the rotation precision of the rotating bracket 312 can be ensured, and the two gluing units 32 can be switched between the gluing position and the gluing position.

It should be noted that the rotation axis P of the rotating bracket 312 may be arranged along the vertical direction Z to rotate the two taping units 32 in the horizontal plane.

The two gluing units 32 are symmetrically arranged about the rotation axis P of the rotating bracket 312, and one of the two gluing units 32 can be overlapped with the other after rotating 180 ° around the rotation axis P of the rotating bracket 312. For example, two rubberizing units 32 may be oppositely disposed along the length direction of the rotating bracket 312, and when the first driving member 311 drives the rotating bracket 312 to rotate, the rotation tracks of the two rubberizing units 32 form a circle.

The first direction X1, which is the direction in which the taping claw 322 is extended or retracted relative to the rotating bracket 312, may be indicated by the direction indicated by the letter X1 in the drawing. The first direction X1 is a direction corresponding to the rotating bracket 312, and represents a moving direction of the rubberizing claws 322 with respect to the rotating bracket 312.

In the embodiment where the glue supplying mechanism and the clamping mechanism are arranged at intervals along the first horizontal direction, when one of the two gluing units is located at the gluing position and the other one is located at the glue taking position, the first direction X1 is parallel to the first horizontal direction.

The second driving member 321 is used for providing a driving force to move the gluing claw 322 relative to the rotating bracket 312 along the first direction X1, so as to enable the gluing claw 322 to perform a gluing operation or a glue fetching operation.

Compared with the case that the two second drivers 321 are arranged at the end parts of the two ends of the rotating bracket 312 in the first direction X1, the two second drivers 321 are arranged to at least partially overlap with each other in a projection onto a plane perpendicular to the second direction Y1, so that the two second drivers 321 have a shorter dimension in the first direction X1, that is, the distance between the two gluing claws 322 is smaller along the first direction X1, so as to reduce the installation space of the gluing mechanism 30, and make the gluing mechanism 30 compact.

Referring to fig. 5, fig. 5 is an enlarged view of a portion a of fig. 2. According to some embodiments of the present application, optionally, as shown in fig. 2 and 5, the rubberizing claw 322 comprises an adjusting portion 3221 and a pair of holding arms 3222, the pair of holding arms 3222 are oppositely arranged, the end of the holding arm 3222 is provided with a vacuum suction hole 3223 for sucking the adhesive tape 70, and the adjusting portion 3221 is used for adjusting the distance between the pair of holding arms 3222.

A pair of holding arms 3222 are mounted to the rotating bracket 312, that is, the two holding arms 3222 are disposed opposite to each other on the rotating bracket 312. For example, two holding arms 3222 are oppositely disposed to the rotating bracket 312 along the fourth direction Z1. One end of the holding arm 3222 is connected to the rotating bracket 312, and a vacuum suction hole 3223 for sucking the adhesive tape 70 is disposed at the end of the holding arm 3222, that is, the end of the holding arm 3222 is used for sucking the adhesive tape 70, so as to implement the adhesive picking operation. The vacuum suction hole 3223 is used to provide a negative pressure to facilitate the suction of the adhesive tape 70 to the end of the holding arm 3222. When the gluing claw 322 is performing the gluing operation, the vacuum suction hole 3223 releases the adhesive tape 70 to apply the adhesive tape 70 to the pole piece 80. It should be noted that the fourth direction Z1 may be parallel to the rotation axis P of the rotating bracket 312, or the fourth direction Z1 may be perpendicular to the rotation axis P of the rotating bracket 312.
