Description

Technical Field

[0001] The utility model relates to the technical field of film tearing structures, and specifically to a pasting and film tearing mechanism using an easy-to-tear sticker. Background Art

[0002] When applying a heat dissipation sticker for a vehicle-mounted touch screen, the release film that plays a protective role on its surface needs to be removed. However, in practice, the release film is completely adhered to the heat dissipation sticker, and there is no designed film tearing position, which leads to the gripper of the existing film tearing mechanism being unable to grip the release film. The operator can only manually tear the release film through experience, resulting in relatively low work efficiency and inability to meet the requirements of mass production. Summary of the Invention

[0003] In view of the above problems, the utility model provides a pasting and film tearing mechanism using an easy-to-tear sticker, which can quickly mechanically remove the release film on the surface of the heat dissipation sticker, with high operation efficiency and meeting the requirements of mass production.

The pressing roller shaft is located at a position away from the Y-direction rotating shaft module relative to the pair of clamping jaws along the X-axis. The pressing roller shaft is used to press the adhesive part of the easy-tear sticker against the release film on the upper surface of the heat dissipation sticker;

[0011] The adsorption machine table is located at the central position in the front part of the machine table;

[0012] An X-direction driving module is arranged on the cross beam. The multi-axis driving module drives the clamping and pressing assembly to act. The working range of the multi-axis driving module for driving the clamping and pressing assembly covers the middle conveying section of the easy-tear sticker reel conveying mechanism and one corner position of the upper adsorption plate.

[0013] Its further features are as follows:

[0014] A pair of clamping jaws of the clamping cylinder include a lower clamping jaw and an upper clamping jaw. The upper piston end of the clamping cylinder is connected to the upper clamping jaw through an inclined swing arm.

[0019] After adopting the present utility model, the heat dissipation sticker is placed on the upper adsorption plate and vacuum adsorbed by the adsorption device. The easy-to-tear sticker moves along the feeding roller shaft towards the receiving roller shaft through the guiding roller assembly, and the moving speed is determined according to the film-tearing speed of the heat dissipation sticker to ensure that each easy-to-tear sticker is reliably utilized for operation. The non-adhesive tearing position of the easy-to-tear sticker is arranged towards a pair of clamping hands of the clamping cylinder. The pair of clamping hands of the clamping cylinder clamp the non-adhesive tearing position of a single easy-to-tear sticker, and then are transported to a corner position of the heat dissipation sticker through the multi-axis driving module. The pressing roller shaft of the pressing cylinder presses down, and the pressing roller shaft presses the adhesive part of the easy-to-tear sticker to fit the release film on the upper surface of the heat dissipation sticker. After the pressing is in place, the pressing roller shaft disengages, and then the multi-axis driving module tears off the easy-to-tear sticker upwards. The easy-to-tear sticker drives the release film to separate from the adsorbed heat dissipation sticker, and then the heat dissipation sticker is transferred to the station for fitting the in-vehicle touch screen. It quickly tears off the release film on the surface of the heat dissipation sticker mechanically, with high operation efficiency and meeting the requirements of mass production.
