Description

1228458 5. Description of the invention (i) [Scope of application of the invention] The present invention relates to a method and a device for peeling a release paper, in particular to a release paper with an adhesive layer from the surface of a flexible circuit board of an inkjet cartridge. Vacuum suction method, device and method for peeling off the edge of the release paper and following the arc track. BACKGROUND OF THE INVENTION Since the manufacturing technology of printers has matured, printers have been widely used in personal computers at a low price. All kinds of inkjet printers are not only rapidly developed and applied in industry, but even the information home appliances in ordinary households are almost equipped with printers. In the structure of the inkjet printer, the inkjet cartridge has always been the most basic device. Generally speaking, in addition to the ink storage container, the other is the inkjet head and its control circuit board that can affect the print quality. In the process of making inkjet cartridges, the precise alignment and adhesion of flexible circuit boards with inkjet heads on inkjet cartridges is one of the keys to determining the quality of inkjet cartridges. In the current manufacturing process, the flexible circuit board (TAB) is adhered to the surface of the inkjet cartridge by an adhesive layer pre-applied thereon, and the release paper on the surface of the adhesive layer must first be adhered before the adhesion Remove, and then stick the exposed adhesive layer to the surface of the inkjet cartridge. In addition to the conventional method of removing the release paper by manual methods, there are also people who use automated machinery to perform this method. This method uses an attractor to directly direct the release paper from the adhesive layer in a direction orthogonal to the release paper. Surface peeling. This method requires sufficient force to peel the release paper from the surface of the adhesive layer. This peeling method will not only cause the adhesive layer and the circuit board

Page 4 1228458 V. Description of the invention (2)-Damage between the two, its decline. Due to the long stripping time, the production system and the yield rate were changed to develop a stripping device for the release paper. The sticking problem caused by the easy-to-break layer of the adhesive layer to peel the release paper caused this problem. It takes a long time to peel off and the required strength is large [^ m ^ The technical subject to be broken by dogs. L Maoming's purpose and overview] Few of the above-mentioned conventional techniques, the problem of the release paper peeling technology in the device and method. For example, the proposed solution for easy peeling of the release paper from the seed branch includes the method of providing a means of adsorbing the release paper, and the release paper is absent at the edge; provided on one side of the near release paper— During the year when the flexible circuit board is fixed, the flexible circuit board B f is fixed to be released from the mold; and the position of the anti-adhesive layer is peeled off from the release paper. The release paper will be sucked. The peeling paper that has been removed, and is not separated from the adhesive layer: :::: The surface of the board is too "the position where the concrete layer is completely peeled off. The trajectory moves to the peeling device exposed by Mao Yue.

Description of the invention (3) The purpose of ensuring the integrity of the adhesive layer, reducing the peeling time of the release paper and the required peeling force. With regard to the features and implementation of the present invention, the preferred embodiment is described in detail with reference to the drawings. [Detailed description of the invention] First, please refer to "Figures 1A and 1B". On the surface of a continuous strip carrier 10, there are a plurality of flexible circuit boards 11 that have been manufactured. One side of these flexible circuit boards 11 is A layer of adhesive 20 is attached, and a piece of release paper 2 1 is attached to the other surface of the adhesive 20. These flexible circuit boards 1 1 are driven by the conveying wheels 3 1 a, 3 1 b. The release paper peeling device designed by the present invention will be moved one by one, thereby peeling the release paper 21 from the adhesive 20, so that the flexible circuit board 11 can be adhered to the inkjet cartridge in the subsequent process. Preset position. The peeling device designed by the present invention includes: a carrier holder 40, which is disposed on the other side of the tape-shaped carrier 1 with respect to the adhesive tape 20, and is responsible for removing the release paper 21 when the peeling operation is performed. The strip carrier 10 and the flexible circuit board 11 are fixed in a stationary state; the adsorber 50 is installed on one side of the strip carrier 10 and faces the edge of the side of the release paper 2 1 for During the peeling operation of the release paper 21, the edge of the release paper 21 is adsorbed; and the traction mechanism 60 has power to drive the adsorber 50 to follow the edge of the release paper 21 that it adsorbs. The trajectory of the arc moves until the release paper 2 1 is peeled from the adhesive layer 20 of the flexible circuit board 1 1. Preferred examples of the above-mentioned respective elements and configurations are as follows.

Ί and the side edge of the release paper 21, then use the suction cup 5 1 to suck the edge of the movement belt (see "Figure 2"), and finally use the swing arm 6 1 3 pendulum ▼ Move the adsorber 5Q to follow the arc determined by the track 62

ill __i 1228458 5. Description of the invention (5), the release paper 21 can be peeled off from the edge of one side of the adhesive layer 20. (See "Figure 3") Second Embodiment In the second implementation of this creation, we made changes to the traction mechanism 60, as shown in "Figure 4". In this embodiment, the adsorber 50 0 A pivot shaft 5 3 is pivotally connected to the end of the swing arm 6 1 3. When the swing arm 6 1 3 drives the adsorber 5 0 to release the release paper 2 1 from the adhesive 2 0, the adsorber 5 0 follows a kind of Take the power take-off shaft 6 1 2 as the center of the circular track, peel the release paper 2 1 from the edge of one side of the release paper 2 1 (see "Figure 5"). Since the adsorber 50 is pivotally connected to the end of the swing arm 6 1 3, during the peeling process of the release paper 21, the adsorber 50 will rotate on its own to adjust the suction cup 5 1 relative to the adhesive layer 2 0 Angle so that the release paper 21 can be peeled off smoothly. [Effect of the invention] The peeling device and method of the release paper applying the present invention is to solve the problem that the adhesive layer is easily damaged and the release time of the release paper is long. As well as process issues such as required power. The present invention has the following effects: 1. The present invention moves the arc to the position where the release paper and the adhesive layer are completely peeled off in a manner of adsorbing the edge of the release paper. This saves effort and ensures the integrity of the adhesive layer. 2. Compared with the conventional technology, it can be seen that this method takes the shortest stripping time during production, and the production capacity can be increased relatively. Although the preferred embodiment of the present invention is disclosed as described above, it is not intended to limit the present invention. Any person skilled in the relevant arts will not depart from the present invention.
