Description

Technical Field

[0001] The present application relates to the field of touch panel manufacturing technology, and in particular, to an anti-overflow glue OCA punching component for vehicle-mounted touch screens. Background Art

[0002] Currently, with the popularization of vehicle-mounted electronic devices, the demand for vehicle-mounted touch screens is increasing day by day. In the production process of vehicle-mounted touch screens, the OCA punching process is one of the key links.

[0003] The OCA used in the existing vehicle-mounted touch screen module has a large viscosity, and the original design is prone to overflow glue, resulting in residual glue on the punching pins and inaccurate positioning of the subsequent single-piece punching positioning pins, resulting in low product yield, increased production costs, and may affect the final use effect of the touch screen.

[0004] Therefore, solving the problem of overflow glue during the OCA punching process, improving product yield and production efficiency, and reducing production costs have become urgent problems to be solved in this field. Summary of the Utility Model

[0005] In order to solve the problem of overflow glue during the OCA punching process, improve product yield and production efficiency, and reduce production costs, the present application provides an anti-overflow glue OCA punching component for vehicle-mounted touch screens.

[0006] The anti-overflow glue OCA punching component for vehicle-mounted touch screens provided by the present application adopts the following technical solutions:

[0007] An anti-overflow glue OCA punching component for vehicle-mounted touch screens includes a fixture frame. A receiving square frame is arranged at the bottom of the fixture frame. Positioning rods are arranged on all four sides of the receiving square frame. An OCA body is arranged above the receiving square frame. The OCA body is connected to the fixture frame through the positioning rods. Positioning holes for cooperating with the positioning rods are formed in the OCA body. A hollowed-out portion is arranged at the upper end of the OCA body, and the hollowed-out portion is located at the punching target position of the OCA body. A fixing component for fixing the OCA body is arranged inside the positioning rod.

[0008] By adopting the above technical solutions, the operator first fixes and installs the OCA body through the fixing component inside the positioning rod installed on the receiving square frame and the positioning holes on the OCA body, and then determines the position to be hollowed out according to the size required for the touch panel, and performs hollowing treatment on the adhered part of the OCA body, avoiding the influence of OCA residual glue on the punching processing accuracy and reducing the defective rate of the product. The fixing component firmly fixes the OCA body and also avoids the situation of damage caused by the operator holding a large piece by hand, reducing the labor intensity of the operator and improving the punching efficiency at the same time.

[0009] Preferably, the jig frame is connected to the punching target position of the OCA body through the positioning rod.

[0010] By adopting the above technical solution, the operator performs laser or cutting engraving treatment at the punching target position corresponding to the OCA body. The punching and cutting assembly is equipped with a special jig frame, and the punching target position is connected to the positioning hole and positioning rod, so that in the subsequent punching operation, the positioning rod at this part does not contact the OCA, thus avoiding the occurrence of residual glue on the punching pin.

[0011] Preferably, the hollowed-out part covers the outer diameter of the punching pin for punching the OCA body.

[0012] By adopting the above technical solution, the area of the hollowed-out part completely covers the outer diameter of the punching pin and is at least greater than 1 mm, ensuring that the edge of the OCA body does not contact any part of the punching pin, thereby avoiding the possibility of residual glue adhesion.

[0013] Preferably, the positioning rods are distributed in a quadrilateral shape on the inner side of the edge of the receiving square frame.

[0014] By adopting the above technical solution, the positioning rods are distributed in a quadrilateral shape on the inner side of the edge of the receiving square frame, making the structure more stable when fixing the OCA body, and the force is evenly distributed during the punching operation, thereby reducing the risk of product scrapping.

[0015] Preferably, the fixing assembly includes a first fixing block and a second fixing block slidably arranged in the positioning rod, and a fixing spring fixedly connected between the first fixing block and the second fixing block. A first sliding groove for the sliding fit of the first fixing block and the second fixing block is formed in the positioning rod, and inclined surfaces are provided on the end faces of the first fixing block and the second fixing block away from the fixing spring.

[0016] By adopting the above technical solution, the operator aligns the positioning holes on the OCA body with the positioning rods provided on the receiving square frame, and then lowers the OCA body. When the OCA body abuts against the inclined surfaces of the first fixing block and the second fixing block, the operator presses the OCA body downward, and the first fixing block and the second fixing block move in the first sliding groove. At this time, the fixing spring is in a compressed state. When the bottom surface of the OCA body abuts against the top surface of the receiving square frame, the first fixing block and the second fixing block pop out under the action of the elastic force of the fixing spring to complete the fixing of the OCA body.

[0017] Preferably, first anti-disengagement plates are fixedly connected to both the front and rear sides of the first fixing block and the second fixing block. Second sliding grooves for the sliding fit of the first anti-disengagement plates are formed in the positioning rod, and unlocking assemblies for unlocking the OCA body are provided on the top surfaces of the first fixing block and the second fixing block.

[0018] By adopting the above technical solution, the first fixing block and the second fixing block move in the first sliding groove, driving the first anti-disengagement plates on both sides thereof to move in the second sliding groove. The arrangement of the first anti-disengagement plates can effectively prevent the first fixing block and the second fixing block from sliding out of the first sliding groove.

[0019] Preferably, the unlocking assembly includes a pressing rod slidably disposed in the positioning rod. The end surface of the pressing rod close to the first fixing block and the second fixing block is provided with an inclined surface. Push grooves for cooperating with the pressing rod are formed on both the first fixing block and the second fixing block. A third sliding groove for slidably cooperating with the pressing rod is formed in the positioning rod.

[0020] By adopting the above technical solution, the operator sequentially pushes the pressing rod. The pressing rod moves in the third sliding groove under the action of pressure. When the inclined surface of the pressing rod matches the push groove, the operator continues to push the pressing rod. Under the combined action of the inclined surface and the push groove, the first fixing block and the second fixing block move together into the first sliding groove. When the first fixing block and the second fixing block are completely inside the first sliding groove, the unlocking of the OCA body is completed.

[0021] Preferably, a second anti-disengagement plate is provided on one side of the pressing rod. An unlocking spring is provided on the second anti-disengagement plate. A fourth sliding groove for slidably cooperating with the second anti-disengagement plate is formed in the positioning rod. One end of the unlocking spring is fixedly connected to the second anti-disengagement plate, and the other end is fixedly connected to the inner wall of the fourth sliding groove.

[0022] By adopting the above technical solution, the operator sequentially pushes the pressing rod. The movement of the pressing rod drives the second anti-disengagement plate to move in the fourth sliding groove, and the movement of the second anti-disengagement plate compresses the unlocking spring. The arrangement of the second anti-disengagement plate can prevent the pressing rod from sliding out of the third sliding groove when moving the device. At the same time, the unlocking spring can provide certain support for the pressing rod in the static state and can also automatically rebound after unlocking is completed, making the operation more convenient.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The operator first fixedly installs the OCA body through the fixing component in the positioning rod installed on the receiving square frame and the positioning holes on the OCA body, and then determines the position to be hollowed out according to the size required by the touch panel, and hollows out the adhered part of the OCA body, avoiding the influence of OCA residual glue on the punching processing accuracy, and reducing the defective rate of the product. The fixing component firmly fixes the OCA body and also avoids the situation that the operator holds a large piece and causes damage, reducing the labor intensity of the operator and improving the punching efficiency at the same time;

[0025] 2. The operator aligns the positioning holes on the OCA body with the positioning rods on the set receiving square frame, and then lowers the OCA body. When the OCA body abuts against the inclined surfaces of the first fixing block and the second fixing block, the operator presses the OCA body downward, and the first fixing block and the second fixing block move in the first sliding groove. At this time, the fixing spring is in a compressed state. When the bottom surface of the OCA body abuts against the top surface of the receiving square frame, the first fixing block and the second fixing block pop out under the action of the elastic force of the fixing spring, completing the fixation of the OCA body;

[0026] 3. The operator sequentially pushes the pressing rod. The pressing rod moves in the third sliding groove under the action of pressure. When the inclined surface of the pressing rod matches the pushing groove, the operator continues to push the pressing rod. Under the combined action of the inclined surface and the pushing groove, the first fixing block and the second fixing block move together into the first sliding groove. When the first fixing block and the second fixing block completely enter the first sliding groove, the unlocking of the OCA body is completed. Description of the Drawings
