Description

Guiding device of anisotropic conductive adhesive film

Technical Field

The utility model belongs to the technical field of conductive film sticking, and particularly relates to a guiding device of an anisotropic conductive film.

Background

Anisotropic Conductive Film (ACF) is a mixture of an insulating adhesive material and a large number of Conductive particles, and can be used to connect two different substrates or lines, so that electrical conduction can be achieved in the vertical (Z-axis) direction, and insulation can be achieved in the horizontal (X-axis, Y-axis) direction. Currently, the ACF is used in many electronic devices, for example, the electronic element can be connected to the liquid crystal screen through the ACF, or the flexible board and the rigid board can be connected through the ACF in a flexible-rigid board, and so on. The application range relates to the fields of electronic components, electronic assemblies, circuit board assembly, display and lighting industry, communication, automobile electronics, smart cards, radio frequency identification, electronic tags and the like.

In the binding process, an anisotropic conductive film 1 'needs to be placed in the middle of the bound object 2', and then the current between the bound objects 2 'can only flow in the z-direction of the vertical axis by the high temperature and high pressure of the binding Tool 3', as shown in fig. 1.

In the present day that electronic devices are miniaturized, the size of the attaching region is miniaturized, the width of the attaching region 4 ' as shown in fig. 3 is reduced to 0.8mm, and in order to ensure sufficient electrical conductivity after the Bonding process, the anisotropic conductive film 1 ' needs to be accurately attached to the region to be attached by the Bonding object 2 ', and the deviation in the width direction is less than ± 0.1 mm. As shown in fig. 2 and 3, the anisotropic conductive film 1 ' needs to be locked at a certain position by the guiding wheel 5 ' when being attached to the Bonding target 2 ', and then the Bonding target 2 ' is controlled to move to a position right below the anisotropic conductive film 1 ', the pressing head is pressed down, and the anisotropic conductive film 1 ' is attached to the attachment region 4 ' with high precision.

The guide wheel 5 'of the existing anisotropic conductive film is a fixture with a fixed width dimension d, and as shown in fig. 4, such a guide wheel 5' can only correspond to an ACF with a single width dimension. When the width dimension of the ACF is changed due to a product or a process, the ACF guiding device needs to replace the guiding wheel with a corresponding dimension to meet a corresponding production requirement.

The obvious disadvantages of the prior ACF guide device are as follows:

1. the operation flow is tedious, and when the device corresponds to the production of different products and processes, the guide wheels used in the previous batch need to be disassembled, and then corresponding new guide wheels are installed again.

2. The positioning needs to be readjusted, the position of the guide wheel changes due to the disassembly and assembly that the guide wheel undergoes, and a corresponding adjustment is needed to install the guide wheel at a determined position.

3. The existing ACF guide wheels need the ACF width sizes to be in one-to-one correspondence, and the manufacturing and storage cost of excessive jigs is high for the production requirements of the ACF with the corresponding different width sizes.

4. As shown in fig. 5, due to the installation manner, a fastening ring is disposed at the front of the ACF guide wheel during installation, which occupies the front space and reduces the design margin of the front space.

Disclosure of Invention

In order to solve the above problems in the prior art, the utility model provides a guiding device for an anisotropic conductive adhesive film, which can flexibly adjust the width of a guiding groove to correspond to anisotropic conductive adhesives with different widths while achieving a high-speed positioning function, thereby improving the production efficiency and reducing the management cost.

The technical scheme adopted by the utility model is as follows:

the utility model provides a guiding device of anisotropic conductive film which characterized in that: the ACF guide wheel comprises a fixed wheel and a movable wheel, wherein the fixed wheel is fixed on a fixed seat, the movable wheel is fixed on the fixed wheel in an adjustable position, and a gap formed between one end face of the fixed wheel and one end face of the movable wheel is the width of the ACF. The jig is fixed by the fixed wheel, the gap is adjusted by adjusting the position of the movable wheel, the re-marking and positioning are not needed, the pattern changing process is simplified, the production efficiency is improved, and the manufacturing and management costs of jigs with different widths are reduced.

Further, the fixed wheel is a cylinder structure with a multilayer ladder structure, and a gap is formed between a first ladder end face of the first end of the fixed wheel and an end face of the movable wheel.

Furthermore, the second end of fixed wheel passes through the fixing base after fixed through solid fixed ring. The fixed ring and the guide wheel are positioned on two sides of the fixed seat, so that the design space is saved for the side of the guide wheel.

Furthermore, the movable wheel is a hollow cylinder, a fixing hole is formed in one side, close to the fixing seat, of the circumferential surface of the movable wheel, and the movable wheel penetrates through the fixing hole through a screw to be detachably and fixedly connected with the fixing wheel.

The utility model has the beneficial effects that:

1. the fixed wheel is fixed, the gap is adjusted by adjusting the position of the movable wheel, the dial indicator is not required to be re-positioned, the model changing process is simplified, the production efficiency is improved, and the manufacturing and management costs of jigs with different widths are reduced.

2. The fixed ring and the guide wheel are positioned on two sides of the fixed seat, so that the design space is saved for the side of the guide wheel.
