Vacuum coating machine operation program mobile phone protective shell UV coating processing knowledge

Please refer to the equipment manual for the specific operation of the vacuum coating machine.

  And the instrument panel pointer display on the device and the labeling instructions under each knob.

  1 Check that the operation control switches of the vacuum coater are in the "OFF" position.

  2 Turn on the main power switch and power the unit.

  3 The low pressure valve is pulled out. Open the inflation valve, after hearing the airflow sound, start the riser bell valve and the bell cover rises.

  4 Install the fixed tungsten spiral heater. The PVDF film and the aluminum cover are attached to the rotating disc. The aluminum wire is placed in a spiral heater. Clean all parts of the bell jar to ensure that there are no impurities.

  5 Drop the bell.

  6 Start the vacuum pump.

  7 Open the composite vacuum gauge power supply (composite vacuum gauge model: Fzh-1A).

  a. The left knob "1" is rotated clockwise to the heating position pointing to the 2 segments.

  b. The pointer in the low vacuum meter "2" moves clockwise. When the pointer moves to 110 mA, the left knob "1" rotates to point to the 2-section measurement position.

  8 When the pointer in the low vacuum gauge “2” moves clockwise again to 6.7Pa, the low pressure valve is pushed in. At this time, the left knob "1" is rotated to point to the 1-section measurement position.

  9 The vacuum coating machine turns on the cooling water, starts the diffusion pump, and heats for 40 minutes.

  10 The low pressure valve is pulled out. Repeat the 7 action program: the lower left knob "1" turns to point to the 2 segment measurement position. The pointer in the "2" of the low vacuum gauge moves clockwise. When the pointer moves to 6.7 Pa, the high pressure valve is opened (the valve stem rotates clockwise).

  When the pointer of the low vacuum gauge "2" moves to the right of 0.1Pa, the filament switch is opened.

  a. The launch, zero point measurement button “9” rotates to point to the launch position.

  b. Turn the lower left knob “1” to point to the 1-section measurement position.

  Rotate the emission control knob "4" to point the pointer in the "5" of the high pressure vacuum gauge to 5.

  The emission, zero point, and measurement knob "9" are rotated to point to the zero position.

  Rotate the zero adjustment knob "10" to point the pointer in the "5" of the high pressure vacuum gauge to the 0 position.

  The emission, zero point, and measurement knob "9" are rotated to point to the measurement position.

  Turn the standard control knob "3" to point the pointer in the "5" of the high pressure vacuum gauge to 10.

  Rotate the "doubler" switch button "8" to point to 10-12. When the pointer in the "5" of the high pressure vacuum gauge moves to the left by more than 1 counterclockwise, then rotate the "doubler" switch knob "8" to point to 10-3. .

  When the pointer of the high pressure vacuum gauge "5" moves counterclockwise more than 6.7 Pa, the workpiece rotation button switch is opened, and the PVDF film of the plated part in the bell jar is rotated.

  Turn on the evaporation button switch. Insert the current sub-plug into the evaporation electrode distribution hole (with 1, 2, 3, 4 holes, you can insert any hole).

  Rotate the right hand regulator handwheel with your right hand and slowly rotate the boost.

Vacuum coating machine mobile phone protective shell UV coating processing knowledge

Vacuum coating machine mobile phone protective shell UV coating processing technical knowledge, the mirror surface of the mobile phone protective shell that can be found on the market is separated from the main body of the mobile phone protective shell, and the two are glued or glued through a layer of double-sided adhesive. Bonding methods are connected together. Considering the strong relationship, it is recommended to refer to the following method when purchasing: If the mirror surface and the shell body have a certain curvature (not a plane) and the mirror surface and the shell body have less contact area, you should choose to use The glue bonding method is connected to the color shell of the mirror surface and the shell body (such as the outer casing of Nokia 8210, 8250, 3310, etc.); if the mirror surface and the shell body are both flat, and the contact area between the mirror surface and the shell body is large, Choose a color shell (such as Siemens 3568i mobile phone, Samsung) A series mobile phone, Motorola V series mobile phone, etc., which is connected by double-sided adhesive.

Technical requirements for hand-painting: high precision: 1440DPI high resolution, can produce promotional materials, digital galleries, fine oil painting and other precision levels; large format: maximum output width of 2.5 meters, to meet most of the current market output tasks Requirements; Consistency: It can be oriented to industrial production, ensuring consistency of mass production screens; multi-material: wood, aluminum-plastic panel, tile, glass, acrylic, Chevron board and other materials can be made; environmentally friendly pigment: UV-curable ink, No odor, fast curing speed, UV protection, high temperature resistance, general chemical composition will not fade.

1 Spray workers must be trained in safety techniques and are not allowed to work without training.

2 All painting equipment and tools must be inspected before painting to ensure that there is no problem before they can work.

3 Ventilation and cleaning of painting workplaces should meet the requirements of GB 6415.

4 In the operation, the enterprise safety technical department shall set up a special person to regularly measure the oxygen content and the flammable gas concentration in the air in the confined space. The oxygen content shall be above 18%, and the flammable gas concentration shall be less than 10% of the lower explosion limit.

5 In-cabin painting work should be carried out with at least two people. If the work place is too narrow and can only accommodate single operation, the other person should be responsible for monitoring.
