What to do if the vacuum pump of the OCA vacuum laminator fails?

Thread Content

　　Those working in the mobile phone repair industry surely know that the OCA vacuum bonding machine is an essential device used for repairing cracked touch screens on phones from brands such as Apple, Samsung, and Xiaomi, as well as for attaching new screens. However, during the use of the OCA vacuum laminating machine, problems such as bubble formation, failure to achieve the desired vacuum level, and the vacuum pump not operating can sometimes occur for various reasons. So, what should be done if there is a fault with the vacuum pump of the OCA vacuum bonding machine? The OCA vacuum bonding machine is designed with regard to the production requirements of small displays and small touch components. Its main working principle involves using a PLC as the control center for the entire system, thereby enabling control over the entire bonding process. The PLC sends pulses through its dedicated pulse output ports to control the pneumatic components, causing the LCD rotation platform to move in a circular motion to the predetermined positions, thus completing the full bonding process for mobile phone touchscreens. 　　We use OCA vacuum laminating machines, and the screens produced by these machines are of good quality. Rotary vane pumps are among the most basic vacuum generation devices in vacuum technology; they are typically used for medium and small-scale applications. Rotary vane pumps come in single-stage and double-stage versions – the double-stage version consists of two single-stage pumps connected in series. Double-stage pumps are generally preferred in order to achieve a higher level of vacuum. If the vacuum pump in the OCA vacuum laminating machine doesn’t work, we need to consider various factors and analyze its working principle, as this will help us identify the cause more quickly. 　　There are two possible reasons why the vacuum pump of the OCA vacuum lamination machine isn’t working: either there is a problem with the vacuum pump or its power is insufficient; alternatively, it could be an issue with the screen lamination machine itself. If these two possibilities have been ruled out, you can reduce the vacuum level of the lamination machine to -90. You also need to check whether the power supply for the vacuum pump of the laminating machine is properly connected and functioning correctly, whether the relay that controls the operation of the vacuum pump is loose or damaged; you can try replacing it. Additionally, check whether the PLC of the laminating machine is sending output control signals to the relay, as well as the components related to the OCA vacuum laminating machine and the vacuum pump. 　　The above information was shared by Yitaoshun Technology at http://www.yitaoshun.com.
