3.4 When the equipment operates normally, the defective rate of components caused by the equipment and transmission lines is less than 1/10000.

3.5 The transmission line is stable, and the repeated positioning error of stopping in place on the transmission unit is ±5mm. The transmission belt is guaranteed to be free of lint and wear during normal use.

3.6 Equipment normal utilization rate: ≥98% (normal, excluding maintenance) calculated based on one year of continuous operation.

3.7 Equipment service life: ≥10 years;

3.8 Noise level when equipment is working: ≤50dbA

3.9 The components have no obvious movement, jumping or deviation during operation. The components are transported smoothly on the entire transmission line without jitter. The deviation size of the components is less than 20mm. The components are not scratched or damaged on the surface, and can meet the requirements of coated glass production;

3.10 The equipment can ensure that the components will not be broken after emergency power failure;

3.11 PLC has an anti-crash function. If human error occurs, the equipment will not cause mechanical or electrical damage to the person;

3.12 Each module or unit of the production line is individually controlled by PLC and touch screen, which can display the working status of each unit to avoid stopping the whole section when a unit needs to be adjusted;

3.13 The material level sensor works reliably, the system interlocking and fault tolerance are good, and the transmission control is conditional detection manual control to avoid human error.

3.14 Each station of the production line can be set in any step, the speed is adjustable, and there are corresponding ports to cooperate with the laying machine, laminating machine and component tester for control.

3.15 The whole line assembly line adopts dual input points. When a switch fails, the system can alarm through the warning light and stop the operation of the relevant section.

3.16 The equipment has gas source, vacuum and other detection functions. When the gas source and suction cup vacuum do not meet the operating conditions, an alarm will be sounded and the relevant operation will be stopped.

3.17 The electrical circuits of each module of the assembly line should be quick-plug type to facilitate installation and maintenance.

3.18 The cables, cable piping, energy medium piping and related installation accessories on the equipment shall strictly comply with national standards and relevant regulations; the oil pipes shall be equipped with thermal insulation layers, the cables shall be threaded through wiring troughs, the external gas pipes shall be protected or made of stainless steel pipes, the inspection ports and inspection doors shall be reasonably designed, and the interior shall be neat.

3.19 The layout of electrical components is neat and standardized. The various gear lines and pneumatic components are concentrated in the pneumatic control cabinet. Each component has a clear annotation, and the line number and pipe number are clearly marked and correspond to the drawings one by one.

3.20 The pumps, motors and other mechanical devices used in the assembly line have good performance and service life, and are easy and quick to maintain. The motors have oil filling and lubrication holes, the slide rails have oil grooves, the equipment is moisture-proof and corrosion-resistant, and the metal parts are rust-proofed.

3.21 Passageways shall be set up at appropriate locations on the production line to ensure maintenance of the laminator and passage of personnel.

3.22 After lamination, the transmission parts of the conveyor line are made of high temperature resistant materials to ensure the normal operation of the equipment.

3.23 The assembly line is equipped with complete safety protection devices and safety warning signs are posted in accordance with national standards. Alarms and faults are indicated by sound and light.

3.24 The control system has vacuum and compressed air pressure alarms.

3.25 All special aircraft have direct access function.

3.26 The equipment has manual /  automatic switching function.
