2) Equipped with an electronic vacuum gauge to facilitate real-time monitoring of laminate chamber pressure changes;

3) Equipment limit vacuum up to 30Pa;

4) The vacuum chamber can quickly reach below 120Pa from the atmospheric state in 120 seconds.

5) With an anti-pressure inflatable protection function to avoid the initial damage caused by the silicone plate breaking and causing component bubbles;

     4. Control system

1) Control mode: automatic or manual control, which can realize automatic feeding, laminating, and discharging and manual feeding, laminating, and discharging.

2) Set vacuum technology, pneumatic transmission technology, PID self-tuning technology, programmable control, and relay control technology can achieve lamination curing complex processes for single-crystal, polycrystalline, amorphous silicon, and other cell components.

3) Real-time display and recording of the characteristic curves of essential system parameters (upper and lower vacuum, table temperature).

4) With the function of segmented pressurization, according to the needs of the process, the number of upper chamber pressurization, lamination pressure, and interval time can be set;

5) The conveyor system adopts a chain transmission structure, allowing continuous material loading and unloading and improving equipment utilization.

6) SIEMENS programmable controllers enable communication with the HMI and meet the requirements of modern industrial automation control.

7) Independent control buttons are set on the inlet and outlet tables to facilitate loading and unloading. The loading table sets the control form of segmented forward, which can put a confident step forward distance according to actual needs. Every time the button is moved, the feeding table automatically advances a certain distance to facilitate feeding.

8) The operation platform adopts a 10-inch high-quality touch screen, the interface is simple, the sensitivity is high, the operation is convenient, it is simple and easy to learn, and the primary operation process is prompted in real-time through sound and light during operation; The process parameters are set, and a variety of process parameters are displayed in the same window, which is convenient for monitoring, and can store a variety of process recipes for production selection.

9) Process parameters are automatically remembered and will not be lost or reset after restarting; significant operating steps are automatically recorded, and data is provided for component quality analysis; the system has a lamination count function, which facilitates the number of shifts and component output and can be used as a reference for equipment repair, maintenance, and replacement rate cycles of vulnerable components.

1. Clean the system
2. General configuration:

1) The upper and lower circulation of the laminator is equipped with brush rollers, which can effectively remove EVA residue after;

2) The upper and lower circulation rollers of the laminator are installed with garbage bins so that EVA, dust particles, and other debris keep the equipment clean and easy to clean;

2. The following belongs to the additional allocation scheme:

The laminate’s upper and lower cycles have an efficient cleaning system with a Kumeisi design. Customer-proven solution for the best laminate cleaning system so far. Get the praise of customers:

1) The high-temperature cloth’s cleaning effect is good. It avoids manual cleaning, makes the equipment close to unattended, saves the workforce, effectively extends uptime, and improves the equipment’s production efficiency.

2) The dirt collection system is equipped with industrial vacuum equipment, which effectively collects debris such as EVA and dust particles, keeps the equipment clean, reduces personnel downtime, cleans time, and effectively avoids secondary pollution of the component backplane.

1. Security measures
2. The equipment is equipped with a fully enclosed integrated protective door to protect the operator’s safety. Provide a mechanical locking latch in the ultimate position of the upper cover to provide mechanical protection for personnel entering the process chamber;
3. Emergency manual operating valves: inflatable valve and switch cap valve. After the power failure, the inflating device can manually fill the upper and lower vacuum chambers of the laminator into the atmosphere; the Switch cover device can manually open and close the upper cover of the laminator;
4. Set up an emergency button; when an emergency occurs, the operator can press it in time to achieve emergency shutdown and ensure the safety of personnel and equipment;
5. The heating system is set with double (PLC detection and over-temperature sensor) over-temperature protection; if the temperature exceeds the defined range, the heating is forcibly cut off, and the alarm stops is alarmed;
6. The heat transfer oil circulation system has a low liquid level detection and alarm shutdown device to prevent the system from drying out without oil and causing danger;
7. Vacuum alarm: when the equipment does not reach the set value within the set time, the system alarms;
8. The component position of the infeed table, if out of the defined range, will alarm and stop the feeding. The discharge table is set up to protect the photoelectric sensor and prevent the components from falling;
9. Alarm points overcurrent, air supply, vacuum, oil level, temperature, etc., to achieve visualization and sound alarm.
