Problems solved by technology

This kind of bonding mechanism, because the front end of the OCA optical adhesive 3' is in a suspended state, that is, there is a large gap between the transmission block 1' and the roller 2', so that the front end of the OCA optical adhesive 3' has no tension, and the OCA optical adhesive 3' has no tension. The optical glue 3' is easy to bend and deform, which leads to the situation that the bonding between the OCA optical glue 3' and the protective film 4' is prone to inadequacy

Embodiment Construction

[0035] Please check figure 2 , a first preferred embodiment of a bonding mechanism of OCA optical glue, a kind of bonding mechanism of OCA optical glue includes a machine (not shown in the figure), OCA optical glue transmission mechanism, protective film delivery mechanism.

[0036] The OCA optical glue transmission mechanism is used to convey the OCA optical glue, which is installed on the machine table and includes a rotatable laminating wheel 10, and the carrier tape 2 bonded with the OCA optical glue 1 bypasses or rests on the laminating The wheel 10 carries out the transmission of the OCA optical glue 1 .

[0037] Such as figure 2 As shown, the OCA optical glue transmission mechanism also includes a first drive roller 11, a second drive roller 12, a third drive roller 13, a fourth drive roller 14 and a fifth drive roller 15 arranged in sequence, and each drive roller The diameter can vary. The laminating wheel 10 is located between the first transmission roller 11 a...

Abstract

The invention discloses an OCA optical adhesive laminating mechanism and laminating method. According to the laminating mechanism, an OCA optical adhesive conveying mechanism is mounted on a machine table and comprises a rotatable laminating wheel, and carrier tape with OCA optical adhesive laminated is wound or placed on the laminating wheel to convey the OCA optical adhesive; a protective film conveying mechanism is arranged on the machine table and comprises a rotatable roller wheel, and a protective film with a circuit layer laminated is wound around the roller wheel to convey the protective film; and when the OCA optical adhesive is conveyed between the laminating wheel and the roller wheel, the top surface of the OCA optical adhesive is laminated to the protective film and synchronously moves with the protective film so as to complete a laminating action. Before the OCA optical adhesive is laminated to the protective film, the bottom surface of the OCA optical adhesive is alwayslaminated to the carrier tape, the front end of the OCA optical adhesive is not suspended, the OCA optical adhesive has enough tension, the OCA optical adhesive is supported and clamped by the laminating wheel and the roller wheel during a whole laminating process of the OCA optical adhesive, and the OCA optical adhesive can be laminated to the protective film smoothly and tightly.

Description

technical field [0001] The invention relates to a bonding mechanism and a bonding method of OCA optical glue. Background technique [0002] The laminating mechanism of the existing OCA optical glue, such as figure 1 As shown, it includes a transmission block 1' on the left and a roller 2' on the right. The right end of the transmission block 1' adopts a triangular structure, and OCA optical glue 3' is placed on the upper surface of the transmission block 1', with circuit layer protection. The film 4' goes around the roller 2' on the right side from the lower side, and is conveyed upward. From figure 1 It can be seen from the figure that the front end of the OCA optical glue 3' is in a suspended state, and the distance of the suspension is D, and the transmission block transports the OCA optical glue 3' to the right until the front end of the OCA optical glue 3' is placed on the surface of the protective film 4'. Driven by 4', the OCA optical adhesive 3' is attached to the...
