Description

Technical Field

[0001] This utility model relates to the field of OCA optical film production technology, and in particular to a laminating machine for OCA optical film production. Background Technology

[0002] OCA is a special adhesive used for bonding transparent optical components (such as lenses). It requires colorless transparency, light transmittance of over 90%, good bonding strength, curing at room temperature or medium temperature, and low curing shrinkage. OCA optical adhesive is one of the important raw materials for touch screens. It is made by creating a substrate-free optical acrylic adhesive, then bonding a release film to the top and bottom layers, resulting in a double-sided adhesive tape without a substrate material.

[0003] In the process of bonding OCA optical adhesive film, the substrate needs to be clamped and limited to ensure accurate bonding. However, existing mounting fixtures are difficult to effectively limit the substrate, which makes it easy for the bonding machine to apply the film crookedly, resulting in a decrease in the efficiency of the bonding machine. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laminating machine for the production of OCA optical adhesive films.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laminating machine for producing OCA optical adhesive film includes a worktable, a fixed column is provided on the top of the worktable, a hydraulic cylinder is provided on the top of the fixed column, and a laminating mechanism is provided at the bottom of the hydraulic cylinder.

[0007] The workbench is provided with a fixed base on the top, and an opening is provided in the middle of the fixed base. A placement plate is provided in the opening, and a limiting mechanism is provided on both sides of the placement plate. The center of the placement plate is located directly below the fitting mechanism.

[0008] In addition, a preferred structure is that the limiting mechanism is provided with a protrusion, and the protrusion has an internal mounting groove, and a pressing block is inserted into the mounting groove, and the pressing block is compatible with the fixing seat.

[0009] Furthermore, in a preferred configuration, the limiting mechanism has a limiting hole on its side, and the protrusion has a locking hole on its side, with the locking hole and the limiting hole on the same path.

[0010] In addition, a preferred structure is that the protrusion has a pair of clamping claws inside, and a spring is provided between the ends of the clamping claws, and the clamping claws are arranged correspondingly on the upper and lower sides.

[0011] In addition, a preferred structure is that the inner wall end face of the clamping claw is provided with a rubber pad.

[0012] In addition, a preferred configuration is that an operation button is provided on one side of the workbench, and the hydraulic cylinder is connected to the operation button via an electrical signal.

[0013] Furthermore, in a preferred configuration, when the limiting mechanism moves to the desired position within the protrusion, a limiting rod is inserted into the limiting hole and the card hole.

[0014] The beneficial effects of this utility model are as follows: First, the hydraulic cylinder at the top of the fixed column drives the bonding mechanism at the bottom to bond the items on the placement plate. Then, the limiting mechanism clamped on both sides of the fixed seat accurately limits the position of the bonded items, so that the bonding machine can bond more precisely during the processing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A laminating machine for producing OCA optical adhesive film includes a worktable 1, a fixed column 3 is provided on the top of the worktable, a hydraulic cylinder 4 is provided on the top of the fixed column 3, and a laminating mechanism 41 is provided at the bottom of the hydraulic cylinder 4.

[0022] The top of the workbench 1 is provided with a fixed seat 5, and the fixed seat 5 has an opening in the middle. A placement plate 51 is provided in the opening, and a limiting mechanism 6 is provided on both sides of the placement plate 51. The center of the placement plate 51 is located directly below the fitting mechanism 41.

[0023] The limiting mechanism 6 is provided with a protrusion 61, and the protrusion 61 has an installation groove 69 inside, and a pressing block 66 is inserted into the installation groove 69, and the pressing block 66 is compatible with the fixed seat 5.

[0024] In addition, the limiting mechanism 6 has a limiting hole 62 on its side, and the protrusion 61 has a locking hole 67 on its side, which is on the same path as the limiting hole 62.

[0025] Furthermore, a pair of clamping claws 63 are provided inside the protrusion 61, and a spring 68 is provided between the ends of the clamping claws 63, with the clamping claws 63 arranged correspondingly on the upper and lower sides.

[0026] Meanwhile, a rubber pad 65 is provided on the inner wall end face of the gripper 63, and an operation button 2 is provided on one side of the worktable 1, and the hydraulic cylinder 4 is connected to the operation button 2 via an electrical signal.

[0027] Furthermore, when the limiting mechanism 6 moves to the desired position within the protrusion 61, a limiting rod 64 is inserted into the limiting hole 62 and the locking hole 67.

[0028] In this embodiment, the object to be bonded is first placed on the placement plate 51 inside the fixing base 5, and the center of the object to be bonded is kept on the same vertical axis as the bonding mechanism 41.

[0029] Then, the material to be bonded needs to be fixed and limited to prevent it from changing position due to force when the bonding machine is working. First, align the opening of the extrusion block 66 at the bottom of the limiting mechanism 6 with the two sides of the placement plate 51 inside the fixing seat 5. Then, insert the mounting groove 69 at the bottom of the protrusion 61 along the end of the limiting mechanism 6 until it stops at the edge of the fixing seat 5. Then, place the two sides of the material to be bonded between the clamping claws 63 inside the protrusion 61.

[0030] Because springs 68 are provided between the clamping claws 63, the top clamping claw 63 will be lifted after the object to be attached is placed between the clamping claws 63. Then, through the restoring force of the springs 68, the clamping claws 63 firmly clamp the object to be attached. Furthermore, because rubber pads 65 are provided on each of the clamping claws 63, no obvious clamping marks will be left when the object to be attached is clamped.

[0031] After clamping, the limiting rod 64 is inserted through the card hole 67 on the side of the protrusion 61 and the limiting hole 62 on the side of the limiting mechanism 41, so that the protrusion 61 is also limited at the same time. Then, the bonding mechanism 41 is controlled by the operation button 2, and the object to be bonded is accurately bonded.

[0032] In this utility model, the hydraulic cylinder 4 at the top of the fixed column 3 drives the bonding mechanism 41 at the bottom to bond the items on the placement plate 51. Then, the limiting mechanism 6 clamped on both sides of the fixed seat 5 accurately limits the bonding of the items, so that the bonding machine can bond more accurately during the processing.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
