Description

Technical Field

[0001] The utility model relates to the field of machining and manufacturing, and particularly relates to an ACF laminating structure with the characteristic of double-sided attachment. Background Technique

[0002] ACF refers to anisotropic conductive film, which is a special coating material coated and laminated (pressed) between substrate a and substrate b, and limits the current to flow only in the vertical axis z direction between substrates a and b. It has both the functions of single-way conduction and gluing and fixing, and can solve some problems of fine wire connection that could not be handled by previous connectors.

[0003] In the prior art, a special ACF laminating device is used to pre-laminate ACF of various widths on TP, LCD or PCB. The ACF laminating machine is divided into three types: manual, semi-automatic and fully automatic. The manual type is completely completed by manual labor, the semi-automatic device needs to be completed with manual cooperation, and the fully automatic type is mainly completed by the device for this process.

[0004] However, since the current ACF laminating device does not have a double-sided mounting structure, it can only perform single-sided and single-time lamination. This single-sided and single-time lamination process not only has low efficiency, but also has secondary pollution and cannot meet the requirements of high-yield mounting.

[0005] In view of this, the technical solution of the present invention proposes an ACF laminating mechanism with the characteristic of double-sided attachment, which has double-sided simultaneous attachment, improves the processing efficiency while ensuring that there is no secondary pollution caused by handling and turnover during production, and has a simple overall structure, is easy to install, use and maintain. Content of the Utility Model

[0006] The technical solution of the present invention aims to solve at least one of the technical problems in the related art to a certain extent. For this reason, the main purpose of the present invention is to provide an ACF laminating structure with the characteristic of double-sided attachment, aiming to solve the problems of secondary pollution causing product defects, rising labor costs and rising equipment costs in the prior art of single-sided ACF adhesive hot pressing and laminating mechanism, where it is necessary to first laminate the front ACF adhesive and then laminate the back ACF adhesive.

[0007] To achieve the above object, the present invention provides an ACF laminating structure with the characteristic of double-sided attachment, including a double-sided laminating component formed by a first laminating mechanism and a second laminating mechanism arranged corresponding to each other up and down, and an automatic feeding component arranged on one side of the double-sided laminating component.

[0008] The first laminating mechanism includes a Y-axis guide rail and a Y-axis slider located on the Y-axis guide rail. A first pressing head is provided at the bottom of the Y-axis slider.

[0009] The second attaching mechanism includes an X-axis guide rail and an X-axis slider located on the X-axis guide rail. A second pressing head coplanar with the first pressing head is provided on the top of the Y-axis slider.

[0010] The Y-axis slider and the X-axis slider are respectively controlled to start and stop through a Y-axis drive and an X-axis drive.

[0011] As a further solution of the present invention, the double-sided attaching assembly further includes a fixing plate for fixing the first attaching mechanism and the second attaching mechanism.

[0012] As a further solution of the present invention, the automatic feeding assembly includes a carrier for placing materials and a pushing and pulling mechanism connected to the bottom of the carrier. The materials correspond to the pressing space formed between the first pressing head and the second pressing head on one side.

[0013] As a further solution of the present invention, both the Y-axis drive and the X-axis drive are replaceable cylinder and motor drive devices.

[0014] As a further solution of the present invention, both the first pressing head and the second pressing head are connected to the Y-axis slider and the X-axis slider through detachable mounting seats.

[0015] As a further solution of the present invention, the pushing and pulling mechanism is a lead screw structure with a scale connected to a servo motor.

[0019] The beneficial effects of the present invention are as follows:

[0020] The ACF laminating structure with double-sided attaching characteristics proposed by the present invention enables the materials to be simultaneously laminated on both sides through the provided first attaching mechanism and second attaching mechanism which are opposite to each other up and down. Since the second attaching mechanism moves in the X-axis direction, it also has the characteristic of laminating surfaces of various sizes, that is, it realizes high-efficiency and fully automated processes such as feeding and double-sided lamination, and also has dynamic lamination that can be adjusted according to different lamination length requirements.

[0029] As follows:

[0030] Please refer to the attached Figure 1-5 , the main structure includes a double-sided attaching component 1 formed by a first attaching mechanism 11 and a second attaching mechanism 12 arranged correspondingly up and down, and an automatic feeding component 2 arranged on one side of the double-sided attaching component 1. The first attaching mechanism 11 includes a Y-axis guide rail 110 and a Y-axis slider 111 located on the Y-axis guide rail 110. A first pressing head 113 is provided at the bottom of the Y-axis slider 111. The second attaching mechanism 12 includes an X-axis guide rail 120 and an X-axis slider 121 located on the X-axis guide rail 120. A second pressing head 123 in the same plane as the first pressing head 113 is provided at the top of the Y-axis slider 111. The Y-axis slider 111 and the X-axis slider 121 are respectively controlled to start and stop by a Y-axis drive 112 and an X-axis drive 122.

[0031] The working principle is as follows:

[0032] During operation, the automatic feeding component 2 sends the material 22 between the first attaching mechanism 11 and the second attaching mechanism 12. At this time, the first attaching mechanism 11 and the second attaching mechanism 12 perform alignment adjustment according to requirements (for example, if a long-sized pressing surface is required, the first pressing head 113 and the second pressing head 123 are adjusted to be completely aligned; when a short-sized pressing surface is required, the X-axis slider 121 is adjusted so that a part of the second pressing head 123 corresponds to the first pressing head 113). After the adjustment is completed, the Y-axis slider 111 moves downward along the Y-axis guide rail 110, and double-sided pressing of the material 22 is achieved through the cooperation of the first pressing head 113 and the second pressing head 123.

[0033] Considering that some material 22 products have a sealed film, structures with automatic film cutting, visual alignment detection, counters and other devices can be provided on the sides of the first attaching mechanism 11 and the second attaching mechanism 12 to make the automation degree higher.

[0034] A preferred embodiment of the present utility model: The double-sided attaching component 1 further includes a fixing plate 10 for fixing the first attaching mechanism 11 and the second attaching mechanism 12.

[0035] To make the alignment degree of the first pressing head 113 and the second pressing head 123 of the double-sided attaching component 1 higher, the first attaching mechanism 11 and the second attaching mechanism 12 are both fixedly arranged on a planar fixing plate 10.

[0036] A preferred embodiment of the present utility model: The automatic feeding component 2 includes a carrier 21 for placing the material 22 and a pushing and pulling mechanism 20 connected to the bottom of the carrier 21. The material 22 corresponds to the pressing space formed between the first pressing head 113 on one side and the second pressing head 123.

[0037] Since it is double-sided pressing at the same time and the second attaching mechanism 12 only moves in the X-axis, taking the bottom surface of the material 22 as a reference, the bottom surface of the material 22 is located above the second pressing head 123. The pushing and pulling mechanism 20 is a lead screw structure with a scale connected to a servo motor, which can achieve precise control of the propulsion distance.

[0038] A preferred embodiment of the present utility model: Both the Y-axis drive 112 and the X-axis drive 122 are replaceable cylinder and motor drive devices.

[0039] A preferred embodiment of the present utility model: Both the first pressing head 113 and the second pressing head 123 are connected to the Y-axis slider 111 and the X-axis slider 121 through detachable mounting seats 13.

[0040] It can adapt to the pressing size requirements of different materials 22. Both the first pressing head 113 and the second pressing head 123 are of detachable and replaceable structures.

[0041] A preferred embodiment of the present utility model: A fixing plate 10, a first attaching mechanism 11, and a second attaching mechanism 12 are all installed in a frame body 3.

[0042] The frame body 3 can adopt a gantry frame, keep perpendicular to the horizontal, and improve the evenness of the pressing surface during pressing.

[0043] The above is only a preferred embodiment of the technical solution of the present utility model, and does not limit the patent scope of the technical solution of the present utility model. Any equivalent structural transformation made under the concept of the technical solution of the present utility model by using the description and drawings of the technical solution of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the technical solution of the present utility model.
