Description

Technical Field

[0001] The utility model relates to the technical field of screen fixtures, in particular to an OCA fixture for vehicle-mounted sensor glass stickers. Background Art

[0002] At present, TP uses OCA glue (optical glue) to bond the cover plate and sensor glass together. Usually, the OCA glue is first bonded to the viewing area on the back of the cover plate. Due to the product design structure and appearance, the OCA glue needs to be bonded to the sensor glass first. In order to reduce the bubbles generated by the bonding of the OCA glue and the sensor glass, this process is completed by a semi-automatic stencil bonding machine (the lower platform of the semi-automatic stencil bonding machine is a mesh, and the upper platform is a hard aluminum platform. The rollers in the mesh on the lower platform are used to move to achieve the bonding of the OCA glue and the sensor glass). Put the OCA glue on the mesh platform, the sensor glass on the upper platform, and then flip the upper platform over through the CCD mark grabber, and the sensor glass is bonded downward with the OCA glue.

[0003] For example, a Chinese utility model patent discloses an anti-crushing fitting fixture for touch screens (publication (announcement) number: CN219831796U), including: a base, an anti-crushing avoidance structure and a positioning component. A limiting groove is provided on the base, and the limiting groove is used to limit and fix the sensor glass. A cover plate platform is also provided on the base, and the cover plate platform is used to carry and limit the cover plate; the anti-crushing avoidance structure is located on the limiting groove, and when the sensor glass is placed in the limiting groove, the FPC is located in the anti-crushing avoidance structure; the positioning component includes a plurality of positioning blocks, and each positioning block is used to limit the position of the cover plate. By setting the anti-crushing avoidance structure in the limiting groove, after the sensor glass is placed in the limiting groove, the FPC can be located in the anti-crushing avoidance structure. In this way, when the equipment is used for pressing, it is possible to avoid the cover plate and the components on the FPC from abutting against each other, which may cause the cover plate to be cracked or the components to be crushed, thereby reducing the production of defective products and improving the production quality of touch screens.

[0004] However, when the inventors implemented this device, they found the following defects: since the sensor glass is bound with FPC (flexible circuit board), the sensor glass has no pre-positioning, and it is difficult to grab the label. When the upper platform is flipped, the FPC carries the IC weight and is easy to fall down, affecting the fit between the sensor glass and the OCA. Utility Model Content
