The screen press laminating machine is the most common equipment in the mobile phone maintenance and screen laminating industry, which integrates laminating, defoaming, vacuum and other processes into one machine. Whether it is purchasing equipment from a new repair shop or upgrading an old shop, how to choose the configuration is an unavoidable issue. This article helps you clarify your purchasing strategy from five dimensions: vacuum system, bonding method, bonding area, defoaming ability, and alignment accuracy.
1、 First, clarify the working principle of the all-in-one machine
The screen press and bonding machine integrated machine usually integrates two functions: vacuum bonding and defoaming. The bonding process involves pressing OCA optical adhesive, screen cover, and display module together in a vacuum environment to avoid residual air bubbles; The defoaming process uses a high-temperature and high-pressure environment to remove the remaining small bubbles after bonding. Before making a purchase, it is important to clarify one's main business: whether to repair the external screen of a mobile phone, replace the cover plate, or do large-sized fitting for tablets, car screens, etc. This directly determines the direction of device configuration.
2、 The vacuum system is the fundamental bottom line for bonding quality
Vacuum value is the foundation of bonding quality. If the vacuum degree is insufficient, air will be trapped inside the screen, and no matter how much bubbles are removed later, it is difficult to completely solve the problems of bubbles and backflow. When choosing, pay attention to the type and vacuum degree index of the vacuum pump: maintenance grade all-in-one machines generally have built-in vacuum pumps or external small vacuum pumps to meet the needs; Industrial grade equipment has higher requirements for vacuum chambers and vacuum stability. Taking Baode's 3D curved vacuum bonding machine as an example, it uses a vacuum chamber combined with a CCD alignment system, with a bonding accuracy of ± 0.1mm and a bonding pressure of 0.05~0.5MPa, which can stably meet the bonding requirements of curved screens.
3、 The bonding method determines the upper limit of yield
Common bonding methods include roller bonding, vacuum flat bonding, airbag bonding, etc. Roller type bonding is suitable for flat or small curved surfaces, with high efficiency; Vacuum flat panel bonding is suitable for large-sized and high-precision scenarios; Airbag style bonding is more friendly to curved screens. When making a purchase, choose based on your main target audience. For example, Baode's medium-sized automatic laminating machine is suitable for precise application of 10-32 inch film materials on the surface of Glass LCM, using CCD automatic alignment correction and roller bonding, with high yield and production capacity, suitable for batch operation of medium-sized screens.
4、 Compatibility between fitting area and model
The bonding area determines the screen size range that the device can handle. If the repair shop mainly focuses on mobile phones, choose devices that can cover mainstream phone sizes; If it involves tablets or car mounted screens, larger fitting area devices are required, while also paying attention to the compatibility of the devices with curved screens and flexible screens. Baode's fully automatic 3D curved surface laminating machine is suitable for laminating processes such as heat dissipation film, explosion-proof film, protective film, and process film for 3D curved OLED display modules. The 86 inch roller type laminating equipment covers large-sized OLED modules, and the product line covers complete laminating requirements from small to large sizes.
5、 Defoamer function and temperature control
Defoaming is an essential step after bonding. The defoaming chamber of the all-in-one machine needs to have stable temperature and pressure control capabilities. Generally, the defoaming temperature is recommended to be between 35 ℃ and 60 ℃, and adjusted appropriately according to the characteristics of OCA adhesive. Industrial grade production lines have higher requirements for uniformity and efficiency in defoaming, and some scenarios may also be equipped with high-pressure defoamers. Baode's high-pressure defoamer adopts SUS304 stainless steel tank body, with a working pressure of 0.1~0.7MPa and a safety level of up to level 2 pressure vessel standard, which can meet the strict requirements of defoaming process.
6、 Alignment accuracy and automation level
The alignment accuracy directly affects the bonding yield. CCD visual alignment, UVW platform, X/Y/θ three-axis adjustment and other configurations can significantly improve alignment accuracy. In terms of automation level, semi-automatic equipment is suitable for small batch and multi variety operations; Fully automatic connecting equipment is suitable for large-scale production. Baode's semi-automatic roller bonding equipment is suitable for attaching OCA, Film and other film materials, using CCD vision+UVW platform alignment, suitable for sizes of 5-15 inches; The fully automatic OLED bonding machine is designed for large-scale OLED module production, helping customers improve production capacity and consistency.
7、 How to choose between maintenance grade and industrial grade
The maintenance grade all-in-one machine pursues cost-effectiveness, easy operation, and small footprint, suitable for mobile phone repair shops; Industrial grade equipment pursues precision, production capacity, and stability, suitable for large-scale production scenarios such as display module factories and vehicle screen production lines. When making a purchase, there is no need to blindly pursue high-end configurations, but to make a comprehensive judgment based on business volume, target audience, and budget. Which brand of laminating machine is good depends on whether the equipment matches your business scenario. Baode has been deeply involved in the field of semiconductor and display bonding for many years, providing a complete product line from semi-automatic bonding equipment to fully automated production lines, and can customize according to customer needs. Whether starting a new store or upgrading a production line, suitable configuration solutions can be found.
8、 Summary
The configuration selection of the screen press bonding machine integrated machine is based on five dimensions: vacuum system, bonding method, bonding area, defoaming ability, and alignment accuracy, combined with its own business scenario to make choices. Repair shops prioritize usability and cost-effectiveness, while large-scale production places greater emphasis on precision and production capacity. Only by selecting the right configuration can the bonding yield be stable and the rework rate be reduced, truly improving efficiency. If you are choosing a vacuum bonding machine, you may want to first sort out your bonding objects and business scale, then evaluate them one by one against the above points, and if necessary, consult the equipment manufacturer for customized solutions.
