Description

Technical Field

[0001] The utility model relates to capacitor or lithium battery production equipment, in particular to a rubber cover hole selection device. Background Art

[0002] In today's capacitor or lithium battery assembly equipment, the rubber cover needs to be pre-aligned with the hole position before being assembled with the element. The existing rubber cover hole selection device usually uses a hole selection seat with two hole selection needles. The rubber cover is placed on the hole selection seat, and the hole selection seat rotates in a circle until the hole selection needle is aligned with the hole of the rubber cover. The hole selection needle passes through the hole of the rubber cover, and the rubber cover falls on the hole selection seat.

[0003] For example, a Chinese patent with patent number CN202020169232.0 discloses a colloid particle hole selection device for a capacitor or lithium battery assembler, wherein the capacitor or lithium battery assembler comprises a colloid particle feeding device and a colloid particle transporting device, which are respectively connected to the front end and the rear end of the colloid particle hole selection device, and are used to transport the colloid particles to the colloid particle hole selection device and receive the colloid particles output by the colloid particle hole selection device. The colloid particle hole selection device comprises: a hole selection seat, comprising a seat body and two hole selection needles fixed on the seat body, wherein the hole selection needles are used to fix the hole position angle of the colloid particles after passing through the colloid particles. , the seat body is used to support the rubber particles; the circular transmission mechanism is connected to the hole selection seat to drive the hole selection seat to move in a circular motion, comprising a first cam, a first connecting rod assembly and a gear transmission assembly, the first cam is fixed on the motor output shaft and rotates with the motor output shaft, the first connecting rod assembly comprises a plurality of connecting rods, which are connected to the first cam and the gear transmission assembly to convert the rotational motion of the first cam into a periodic swing of the connecting rod, and the gear transmission assembly is connected to the hole selection seat to convert the periodic swing of the connecting rod into a periodic circular rotation of the hole selection seat.

[0004] However, there is contact friction between the hole selection needle and the rubber cover. When the hole selection seat rotates in a circle, the rubber cover rotates together with the hole selection needle under the friction force, resulting in a longer hole selection time and a lower hole selection efficiency.

When the rubber cover 100 is loaded between the hole selection seat 20 and the friction pressure head 40, the pressure head lifting mechanism 50 first drives the friction pressure head 40 to descend so that the friction surface 41 of the friction pressure head 40 is pressed on the rubber cover 100, and then the hole selection rotating mechanism 30 drives the hole selection seat 20 to rotate so that the two hole selection needles 21 on the hole selection seat 20 are respectively aligned with each other.
