The manufacturing process of LCD advertising machine is also a matter of concern to consumers. Whether the manufacturing process is complete is also related to product quality. Next, I will introduce the production process and process operation instructions of LCD advertising machine manufacturers.
LCD advertising machine
1. Shell standards:
Appearance: incoming inspection LCD advertising machine face frame, bottom shell, base standard: no wear, no bumps, no defect in the screw hole position of the lock cover, no uneven spraying, and the fixed position of the LCD screen and the board can only be put into storage. (full detection)
1. The appearance of the carton should not be worn, scratched or dirty (must be clean, tidy and standard).
2. The hardness of the carton (not easy to be damaged), the sealing glue should be uniform and tidy.
3. The vertical machine must not have scratches, protrusions, depressions, deformation, uneven spraying and sundries (must be smooth).
4. The back cover cannot be deformed, bulged, sunken, scratched, screw holes are in the wrong position, and paint is peeled off.
5. The glass is peeled off, the size is wrong, and the place without paint (display area) cannot have paint.
6. There can be no gap between the profile and the glass, no deformation, scratches, depressions and protrusions, sundries.
7. The hole position of the screen bracket should not have errors.
8. The installation board is easy to wipe off the glass paint, the bracket hole (decoder board), and the bracket (switch) are too high to lift the back cover.
9. The small door of the back cover is not locked with the back cover, and the looseness is not firm.
10. The stable detection of the anti-theft device of the lock piece, and the connection of the interface and other lines is decent and beautiful.
Second, LCD screen detection:
South Korea LG, AUO, Chi Mei A-class LED industrial control LCD panel, resolution 1920*1080.
3. Circuit part test:
1. Power board: industrial-grade power board. After each batch of incoming materials, check whether the power and output voltage of the power board meet the standard with the load (the power board has a stable supply chain).
Detection method: household voltage measuring instrument, as well as product power consumption and live protection test.
2. Mainboard: HD decoding mainboard, check whether the HDMI and VGA interfaces are in good condition.
3. Cooling device: whether the cooling fan and the refrigeration industrial air conditioner are in good condition and the line interface is clear.
Second, LCD screen detection:
Brand new LED LCD screen, resolution 1920*1080
3. Circuit part test:
1. Power board: industrial-grade power board. After each batch of incoming materials, check whether the power and output voltage of the power board meet the standard with the load (the power board has a stable supply chain).
Detection method: household voltage measuring instrument, as well as product power consumption and live protection test.
2. Motherboard: High-definition decoding motherboard, performance running points, and whether the graphics card network card equipment is accurate, check whether the HDMI and VGA interfaces are in good condition.
3. Cooling device: whether the cooling fan and the refrigeration industrial air conditioner are in good condition and the line interface is clear.
Fourth, the whole machine delivery process:
The purpose of the equipment test is to verify whether the quality and configuration of the equipment are qualified. Each equipment is tested as follows:
A. Device startup
Startup: Turn the power on and off for a single device multiple times, and observe whether it starts normally each time.
B. Equipment status
With the product manual, check whether the indicator light of the device is normal.
C. Port inspection and functional testing
Check the port of the device to see if it can be connected through the port and operate the device for testing. If the test result conforms to the product description, it is normal.
D. Physical examination
Physical inspection of the equipment, inspection of the factory model, serial number, origin, accessories, materials, software, etc. of the equipment, is normal if it is consistent with the contract and product description.
E. Visual inspection
Carry out visual inspection of the equipment, and check that the appearance of the equipment should be neat, the size, shape, symbol design or contract requirements, no obvious color difference, no obvious rust, and the logo is clear and correct.
The above is the production process of Rongda Caijing's production and manufacture of LCD advertising machines. The process is related to product quality, a complete manifestation, and can reflect the company's strength. Whether each product can be done well.
