Abstract
Description
Technical Field
[0001] This utility model relates to the field of OCA optical adhesive, and in particular to an OCA optical adhesive pressing device. Background Technology
[0002] OCA is a special adhesive used to bond transparent optical components. It is one of the important raw materials for touch screens. It is made by making optical acrylic adhesive without a substrate, and then bonding a release film to the top and bottom layers. It is a double-sided adhesive tape without a substrate material.
[0003] The announcement number CN221365979U discloses "An efficient pressing device for OCA optical adhesive", which includes a pressing main body, a worktable, a pressing platform set on the worktable, and a pressing top set on the pressing main body. The pressing top and the pressing platform are arranged opposite to each other. Support and buffer structures are provided at both ends and the bottom of the worktable, which include side support structures and bottom support structures. The supporting force of the bottom support structure is greater than that of the side support structure. The support and buffer structure includes a fixed tube and a compression spring. One end of the fixed tube is threaded to an adjusting screw, and the other end of the fixed tube is limited to slide with a second sliding plate. A support block is fixedly installed on the outer end of the second sliding plate. A lower fixed plate is fixedly installed at the bottom of the pressing platform. The segmented structure avoids the problem of excessive pressure on the pressing top causing damage to the equipment, and the problem of limited pressure on the material on the pressing platform due to the material moving down with the pressing platform, which affects the pressing efficiency.
[0004] Although the aforementioned OCA optical adhesive high-efficiency lamination device has certain advantages in terms of buffering capacity, it is not convenient to perform lamination operations on different touch screen substrates because the width and thickness of the substrate may be inconsistent. This requires frequent adjustments to the lamination device, reducing production efficiency and increasing production costs. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an OCA optical adhesive pressing device, comprising a conveyor belt, baffles, a width structure, and a thickness structure. Baffles are installed on both the front and rear sides of the upper end of the conveyor belt. A width structure is installed on the left side of the front end face of the baffles. A thickness structure is installed on the upper end face of the baffles. The width structure includes a motor, a bidirectional screw, a limiting rod, and a push plate. The output end of the motor extends out of the baffle and is connected to one end of the bidirectional screw via a transmission connection. The other end of the bidirectional screw is rotatably connected to the baffle through a bearing. A limiting rod is provided on the right side of the bidirectional screw.

[0008] Optionally, the pressing structure includes a shell, a rectangular groove, a straight rod, a sliding plate, and a telescopic arm. A rectangular groove is provided in the middle of the lower end face of the shell. The left and right side walls of the shell are fixedly connected to the straight rod. Sliding plates pass through both sides of the straight rod. The lower sides of the two sets of sliding plates are fixedly connected to one end of the telescopic arm, respectively. The upper end face of the shell is fixedly connected to the push rod end of the electric push rod.
[0009] Optionally, the bidirectional screw and the limiting rod are parallel to each other.

[0023] Please see Figure 4 This utility model provides an OCA optical adhesive pressing device. The thickness structure 4 includes a mounting plate 41, a rectangular plate 42, an electric push rod 43, and a pressing structure 44. The rectangular plate 42 is mounted on the upper end surface of the mounting plate 41. The electric push rod 43 is mounted in the middle of the upper end surface of the rectangular plate 42. The push rod end of the electric push rod 43 extends out of the rectangular plate 42 and connects with the pressing structure 44. The lower end surface of the rectangular plate 42 is fixedly connected to the baffle 2.
[0024] Please see Figure 5This utility model provides an OCA optical adhesive pressing device. The pressing structure 44 includes a shell 441, a rectangular groove 442, a straight rod 443, a sliding plate 444, and a telescopic arm 445. The rectangular groove 442 is opened in the middle of the lower end face of the shell 441. The left and right side walls of the inner side of the shell 441 are fixedly connected to the straight rod 443. The sliding plates 444 pass through the left and right sides of the straight rod 443.

[0026] First, place the new device in the desired location and connect the circuitry.
[0027] The material to be pressed is placed on the upper surface of the conveyor belt 1. The motor 31 is controlled to operate. The output end of the motor 31 drives the bidirectional screw 32 to rotate. The bidirectional screw 32 drives the push plate 34 to move through the limiting rod 33. While the push plate 34 moves, it pushes the sliding plate 444 to move. The two sets of sliding plates 444 slide along the inner wall of the rectangular groove 442. The two sets of sliding plates 444 adjust the length of the telescopic wall 445. At the same time, the sliding plate 444 compresses the spring 446, causing the spring 446 to contract.

The outer shell 441 drives the straight rod 443 to move, the straight rod 443 drives the sliding plate 444 to move, and the sliding plate 444 drives the telescopic arm 445 to move. According to the extension length of the electric push rod 43, in conjunction with the conveyor belt 1, the telescopic arm 445 can perform pressing processing on the material, achieving the effect of easily adapting to substrates of different widths and thicknesses. It is convenient to adjust according to the width and thickness of different substrates, improve production efficiency, and reduce production costs.
