Abstract

The utility model relates to the technical field of coating equipment, in particular to a cage driving mechanism and vacuum coating equipment. The cage frame driving mechanism comprises a driving module and a driven module arranged on one side of the driving module, wherein the driven module comprises a driving source, a guide frame, a guide shaft, a supporting disc and an anti-rotating frame, an output shaft of the driving source is connected with a first end part of the guide shaft, the supporting disc is rotatably arranged at a second end part of the guide shaft, and the anti-rotating frame is arranged on the guide shaft and can move back and forth on the guide frame. The driving module drives the cage frame to rotate at the driven module. The output shaft of the driving source jacks up the supporting disc through the guide shaft. Because the anti-rotating frame is arranged on the guide shaft and can move back and forth on the guide frame, the anti-rotating frame is matched with the guide frame, so that the guide shaft can only move up and down and can not rotate, the output shaft of the air cylinder can not rotate, and the condition of damaging the air cylinder is avoided. Meanwhile, the guide shaft is matched with the guide frame, and the cage frame cannot be inclined at any height.

Description

Cage driving mechanism and vacuum coating equipment Technical Field The utility model relates to the technical field of coating equipment, in particular to a cage driving mechanism and vacuum coating equipment. Background Some vacuum coating equipment in the market can use a cage, and a product is placed on the cage to finish coating. When coating film, the cage frame rotates in the coating film chamber, and the products on the cage frame finish coating film one by one. When the cage frame rotates in the film coating cavity, the cage frame needs to be jacked up firstly, and then the cage frame is driven to rotate through a motor. However, the cage is lifted up by the output shaft of the cylinder and then rotated, as in the case of jamming of the bearing, the rotating force is transmitted to the output shaft of the cylinder, which may damage the cylinder. For example, CN202411482016.0 discloses a multi-chamber sputter coating device, and specifically discloses that "the third driving cylinder can drive the second rotating seat to move upwards, so that the first rotating seat and the second rotating seat correspondingly abut against the upper end and the lower end of the annular cylinder seat". The cage is directly jacked up through the output shaft of the air cylinder, and when the cage rotates, the bearing is blocked, and the rotating force can be transmitted to the output shaft of the air cylinder, so that the air cylinder can be possibly damaged. Disclosure of utility model In view of the above, the present utility model addresses the drawbacks of the prior art, and it is a primary object of the present utility model to provide a cage driving mechanism, which can ensure that the output shaft of the cylinder does not rotate, and prevent the cylinder from being damaged, thereby overcoming the drawbacks of the prior art.
