Embodiment 1

[0020] Embodiment 1: as Figure 1~5 As shown, in this embodiment, the present invention relates to a 3D glass film sticking device, which includes a horizontally movable carrier platform 10, a carrier jig 20 is arranged above the carrier platform 10, and the carrier tool 20 can be fixed on the carrier platform Above, the upper surface of the carrying jig has a positioning groove 21 for placing a glass cover plate, and a pre-positioning pressing assembly 30 is arranged above the carrying jig 20, and the pre-positioning pressing assembly 30 includes a fixing plate 31, The middle part of the lower surface of the fixing plate is provided with a silicone head 32, and the silicone head is covered with an annular pressure plate 33. A spring assembly 40 is arranged between the fixing plate and the annular pressure plate. A thermal light source device 50 is provided to irradiate and heat the membrane to make the glue on the bonding surface of the membrane viscous.

Embodiment 2

[0034] Embodiment 2: On the basis of Embodiment 1, in this embodiment, a heating circuit and a heating element can also be arranged in the carrying fixture, and the heating element contacts the designated position of the glass cover to heat the glass cover, because the film After the glue on the bonding surface of the film is activated by heat, if it is not bonded in time, the glue may fail after cooling. If the improvement is to heat the glass cover first, the film will be bonded at the same time as the film is heated, which can avoid above question.

[0035] In this embodiment, the thermal light source device can also be used to irradiate the designated position of the glass cover for irradiation and heating. After the film is in contact with the glass cover, through heat conduction, the glue reaches the activation temperature and becomes sticky.

Abstract

The present invention relates to a 3D glass film sticking device, which comprises a horizontally movable carrier, a carrier jig is arranged above the carrier, the upper surface of the carrier jig has a positioning groove for placing a glass cover plate, the carrier A pre-positioning pressing component is arranged above the fixture, and the pre-positioning pressing component includes a fixing plate, a silicone head is arranged in the middle of the lower surface of the fixing plate, and an annular pressure plate is sleeved on the silicone head. A spring assembly is arranged between the annular pressing plates, and a thermal light source device is arranged between the silicone head and the bearing jig to irradiate the heating film to make the glue on the bonding surface of the film stick. The design of the invention is reasonable and the structure Simple and easy to use, it will not affect the film sticking due to the excessive curvature of the edge of the glass cover, resulting in voids or tearing of the film, suitable for film lamination of glass cover with a bending angle greater than 60°, high efficiency Reduce the defect rate and have broad application prospects.

Description

technical field [0001] The invention relates to a 3D glass film sticking device and a process method thereof. Background technique [0002] At present, in the production of mobile phones and other equipment in the industry, the front and rear covers mainly use glass cover plates. During the cover plate processing, it is often necessary to stick a film on the surface of the glass cover plate. In the past, the most used glass cover is the 3D glass cover with curved edges, and the bending angle is usually less than 60°. The conventional method in the industry is to use a film with OCA glue for lamination, which can meet the demand. With the development of cover plate processing technology, it is now possible to produce glass cover plates with edge bending angles greater than 60°, especially glass cover plates with four-sided bending and bending angles of 60°~90°. , because the inner side of the arc angle cannot be adhered to tightly, resulting in gaps or diaphragm tearing. ...
