Waste discharging and material collecting device and waste discharging method for OCA material

Abstract

The invention relates to a waste discharging and material collecting device and a waste discharging method for an OCA material. The waste discharging and material collecting device comprises a conveying platform and a waste discharging bracket; the conveying platform is provided with a main rubber roller group, a waste discharging roller, a small pass roller, a covering membrane roller group, a waste discharging knife, an auxiliary rubber roller group and a driving mechanism; the waste discharging bracket is connected with a waste material winding mechanism, a transfer membrane unwinding mechanism, a transfer membrane winding mechanism and a controller, wherein the controller is used for controlling the waste material winding mechanism, the transfer membrane unwinding mechanism, the transfer membrane winding mechanism and the driving mechanism to run interactively; the waste discharging method comprises the following steps of: (a) introducing the OCA material; (b) removing and windinga covering membrane waste material; (c) compounding a transfer membrane with exposed OCA glue; (d) removing the transfer membrane from the OCA material and taking away redundant OCA glue; and (e) obtaining an OCA material finished product. The waste material winding mechanism, the transfer membrane unwinding mechanism and the transfer membrane winding mechanism are utilized for discharging the covering membrane waste material and discharging redundant OCA glue of the die-cut OCA material, full-automatic waste discharging operation is realized, and the production efficiency and the product quality are improved.

Description

Technical field: [0001] The invention relates to a waste discharge and collection device and a waste discharge method for OCA materials. Background technique: [0002] OCA material is an electro-optical film formed by connecting two release films with OCA glue. It is widely used in the field of touch screens. To make OCA materials for touch screen products, they must undergo a die-cutting process to transform the original into a continuous strip. The OCA material is cut into the required shape, so that the OCA glue has the characteristics of meeting the requirements and neat borders, and then used. After die cutting, the OCA glue on the OCA material except the product shape is waste, and these waste materials need to be removed. Removal, the traditional method of removing waste is manual removal. This method is inefficient, and due to the poor stability of manual operation, when removing waste rubber, it is easy to cause the product to overflow and stick to the waste glue, making...

[0002] OCA material is an electronic optical film formed by connecting two layers of release film with OCA glue. It is widely used in the field of touch screens. To make OCA materials into products for touch screens, it must go through a die-cutting process to convert the original into a continuous strip. Cut the OCA material into the required shape, so that the OCA glue has the characteristics of meeting the requirements and neat boundaries, and then use it. After die-cutting, the OCA glue on the OCA material except for the product shape is waste, and these wastes need to be processed. Removal. The traditional method of removing waste is manual removal. This method is inefficient, and due to the poor stability of manual operation, it is easy to cause the glue of the product to overflow when removing the waste glue and cause it to stick to the waste glue, making the glue boundary of the final product Untidy, affecting product quality
