Description

Technical Field

[0001] The present invention relates to the technical field of electronic product screen laminating, and in particular to a double-sided film-tearing laminating device and a method thereof. Background Art

[0002] With the development and upgrading of electronic products such as smart phones, consumers' demand for product experience is also constantly upgrading. Traditional candy-bar phones have reached a bottleneck in meeting users' demand for large screens and cannot meet users' demand for smaller sizes and larger display areas. The emergence of flexible folding screens can meet users' demand for large screens to a greater extent while ensuring portability, and has therefore become an emerging technology pursued by mobile phone manufacturers.

[0003] The existing film replacement technology for ultra-thin flexible glass bonding products has significant defects, which are mainly manifested in the following aspects: First, the currently widely used manual blind lamination method is not only inefficient, but also due to factors such as the operator's skill level and emotional fluctuations, it is difficult to maintain consistent lamination quality, and it is easy to have unevenness, bubbles, wrinkles and other undesirable phenomena. These defects seriously affect the quality of the final product; secondly, after manual lamination, it is usually necessary to use a laser cutting machine for cutting. This process not only increases the complexity of the production process, but also may generate dust and heat during the laser cutting process, causing potential damage to the product; thirdly, even if a copy machine is used for positioning and lamination, although more precise lamination positioning can be achieved, manual operation is still required, and it can only be done one by one on one side, which leads to a slow production rhythm and limited production capacity; finally, due to the slow rhythm, in order to meet production needs, a large amount of equipment needs to be invested, which not only increases production costs, but also puts higher requirements on production space.

[0004] For example, patent CN117141811A discloses a method for applying a protective film to a folding screen. The steps of the method include preparing the electronic product to be applied and the protective film, cleaning the screen of the electronic product to be applied, placing the electronic product to be applied in a first preset position, tearing off the bottom release film, placing the protective film in a second preset position, pasting the protective film on the screen of the electronic product to be applied, and detecting the position deviation between the screen and the protective film. The method for applying a protective film to a folding screen places the electronic product to be applied in a first preset position, places the protective film in a second preset position, and then pastes the protective film on the screen of the electronic product to be applied. It can only be done one by one on one side, the production rhythm is slow, and the production capacity is limited. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a double-sided film peeling and laminating device and method thereof, so as to achieve the purpose of effectively improving production efficiency.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A double-sided film peeling and laminating device includes a product feeding structure and two processing lines for film peeling, product surface cleaning and film laminating. A film taking mechanism is provided for each processing line, and a flipping structure for flipping the product is provided for the corresponding processing line.

[0008] The product feeding structure comprises a feeding area, a pre-alignment area and a code reader reading area which are arranged in sequence.

[0009] The film tearing process in the processing line is completed by a film tearing robot.

[0010] In the processing line, a glass photographing process is arranged before film application.

[0011] The films in the processing line are coated by a robot arm.

[0012] It also includes a material unloading structure, which includes a material unloading robot and a material unloading box.

[0013] A waste film frame is provided in the processing line corresponding to the film tearing process.

[0014] A code spraying and reading area is arranged after the last film laminating process in the processing line.

[0015] A double-sided film tearing and laminating method comprises the following processes: manually loading the product with the UTG side facing upward, pre-aligning and scanning the QR code on the UTG protective film and uploading it to the MES system, transporting it to the laminating platform and tearing the film by a film tearing robot arm, cleaning the UTG surface through a cleaning process, removing the half-cut protective film by a film laminating mechanism and covering the UTG, the UTG laminating platform withdraws to the flip platform, flips and loads the product to the PET platform, and the film is also torn by the film tearing robot arm, and is laminarized by the PET laminating mechanism after cleaning. After laminating, the PET laminating platform withdraws and is transported to the code spraying and code reading mechanism by a material unloading robot, unloads the material to the silo, and the equipment movement process ends.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The double-sided film-tearing and laminating equipment and method are reasonably designed. Through the double-sided film-tearing and laminating method, the production process is simplified, the laminating speed is increased, the laminating quality is ensured, the number of equipment and production costs are reduced, and the production efficiency and quality of flexible glass bonding products are improved. The visual system and robot arm are used to ensure precise alignment and uniform coverage during the laminating process, while avoiding the instability and contamination risks that may be caused by manual operation, significantly improving production efficiency, reducing production cycles, and ensuring product consistency and reliability, meeting the market demand for high-quality flexible glass products.

DETAILED DESCRIPTION

[0023] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, the double-sided film peeling and laminating equipment includes a product loading structure, two processing lines for film peeling, product surface cleaning, and film laminating, a film taking mechanism is provided for each processing line, and a flipping structure for flipping the product is provided for the corresponding processing line.

[0025] The product feeding structure includes the feeding area, pre-alignment and code reader reading area which are set up in sequence. The code spraying and code reading area is set up after the last laminating process in the processing line. The production system connected with MES is adopted. The loading automatically scans and records the product information. After laminating, the new information code spraying and code scanning records are issued through the uploaded information, which can effectively trace the product and analyze the production records.

[0026] The film-tearing process in the processing line is completed by a film-tearing robot; the glass photography process is set before film application in the processing line; the film application in the processing line is coated by a robot arm. The use of a visual system and a robot arm ensures accurate alignment and uniform coverage during the coating process, while avoiding the instability and contamination risks that may be caused by manual operation, significantly improving production efficiency, reducing production cycles, and ensuring product consistency and reliability, meeting the market demand for high-quality flexible glass products.

[0027] Furthermore, the present invention also includes a material unloading structure, which includes a material unloading robot and a material unloading box; a waste film frame is provided in the processing line corresponding to the film tearing process; the production process is simplified and the operation efficiency is improved.

[0028] One processing line has surface cleaning Ⅰ15, glass photography Ⅰ14, and film sticking station Ⅰ12, and a film removal station Ⅰ13 is provided corresponding to the film sticking station Ⅰ process; the other processing line has surface cleaning Ⅱ8, glass photography Ⅱ9, and film sticking station Ⅱ10, and a film removal station Ⅱ11 is provided corresponding to the film sticking station Ⅱ process; the two processing lines are arranged side by side with a compact structure; the flip robot is movably arranged, and the processing is efficient.

[0029] The double-sided film peeling and laminating method of the present invention comprises the following steps:

[0030] Manual loading 1 puts the product UTG side up, pre-aligns 2 and scans the QR code on the UTG protective film through the barcode reader 3 and uploads it to the MES system, then moves it to the laminating platform, the film tearing robot 7 tears the film, and the UTG surface is cleaned through the cleaning process. The laminating mechanism removes the half-cut protective film and covers the UTG. The UTG laminating platform withdraws to the flipping platform, and the flipping robot 4 flips and loads it to the PET platform. The film is also torn by the film tearing robot arm, and after cleaning, it is laminated by the PET laminating mechanism. After the lamination is completed, the PET laminating platform withdraws and is moved to the coding and reading mechanism by the unloading robot. After coding and reading 5, the material is unloaded to the unloading box 6, and the equipment movement process ends.

[0031] The equipment of the present invention combines the thinness and softness of ultra-thin glass, and develops an automatic film tearing and laminating method based on the previous manual film tearing and flipping technology. The equipment adopts two sets of laminating units, including PET laminating and UTG laminating, as well as cleaning and MES docking calibration equipment that can trace product information, and accurately laminar products through visual positioning. This invention abandons the characteristics of low production capacity and poor precision of the original single-piece laminating equipment, greatly improving the production capacity of the laminating process after ultra-thin flexible glass bonding. At the same time, the equipment is designed to automatically load and unload materials, effectively improving the product yield.

[0032] Specific preferred embodiments of the present invention are:

[0033] The process section described in the present invention is the film change before packaging and shipment; it is mainly used for film change after three-in-one lamination, and the film is torn and replaced by pressing to ensure that the product will not be affected during transportation and transit. At the same time, it can also connect to MES to upload the QR code record on the surface of the product to MES before film change and then issue a new product serial number. After the film is changed, the new product serial number will be sprayed on the surface of the product that has successfully changed the film.

[0034] The equipment consists of two parts: UTG tearing and laminating, and PET tearing and laminating. The UTG part is composed of loading, scanning, tearing, cleaning, and laminating. The UTG is flipped to the PET side after laminating. The PET part is composed of tearing, cleaning, laminating, coding, scanning, and unloading. The equipment workflow is as follows: manual loading with the UTG side facing up, pre-alignment scanning of the QR code on the UTG protective film and uploading it to the MES system, transporting it to the laminating platform and tearing the film by the tearing robot arm, cleaning the UTG surface with plasma and USC, and removing the half-cut protective film from the UTG by the laminating mechanism. The UTG laminating platform withdraws to the flipping platform, flips and loads to the PET platform, and the film is also torn by the tearing robot arm. After cleaning by plasma and USC, it is laminated by the PET laminating mechanism. After laminating, the PET laminating platform withdraws and is transported to the coding and reading mechanism by the unloading robot, unloaded to the silo, and the equipment movement process ends.

[0035] The present invention has the following advantages:

[0036] Abandon the previous single-sided manual lamination method, and improve product production efficiency by automatic film tearing and lamination; ensure the accuracy of product lamination position through visual positioning of each workstation; adopt fully automatic connection method, including automatic loading and unloading, two groups of lamination linkage, etc., to reduce labor costs and improve product yield; adopt a production system connected with MES, automatically scan and record product information when loading, and send new information through the uploaded information after lamination, which can effectively trace product information.

[0037] The above is only an explanation of the preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0038] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
