Before the used YAMAHA placement machine is ready to go online, the placement machine should be inspected tested. Although the placement machine manufacturer will debug the placement machine before the product leaves the factory, in order to be safe better put into work, it should be The performance of the main indicators of the placement machine is tested.

1. The type, specifications, orientation, substrate size range of the patch can be posted on the specifications!

2. SMT speed: The test CPH installation speed is less than 60% of the nominal IPC 9850 speed, the SPC speed does exceed 2 times the nominal speed;

3. Flight movie rate: no more than 3/1000

operating system

1. Various indicators, buttons operation handles are complete in appearance, the operation display are normal;

2. The computer system is working normally;

3. The input output system works normally.

Mechanical Parts

1. The transmission belt, chain connecting rod are complete without aging damage.

2. The transmission guide rails the screw run smoothly smoothly, without abnormal noise oil leakage.

Control section

1. The drive cylinder, solenoid valve pipeline have no foreign body clogging at the connector no air leakage. The driving cylinder solenoid valve work normally without noise;

2. The compressed air drying filtering device is intact;

3. The vacuum degree of the LED chip head is less than 500 mmHg, the mounting accuracy is a large deviation between the center of the component the center line of the corresponding pad, exceeding 1 ≤ 3 (visual inspection) of the component foot width, the incidence of abnormal displacement is More than 3/1000.

The appearance of the instrument is good, the indication is accurate, the reading is conspicuous, it is within the qualified period of use. The equipment is regularly maintained inside outside, kept clean, free of oil corrosion, the spare parts are arranged in an orderly manner, the equipment is well lubricated.

The placement machine is the core installation equipment in SMT production. Before preparing for installation, you still need to know:

1. Prepare relevant product process documents.

2. According to the installation schedule of the product process file, extract the materials (PCB, components) check them.

3. The opened PCBs are cleaned baked according to the length of the opening time whether they are wet polluted.

4. After unpacking, inspect the parts handle the damp parts according to the management requirements of SMT process parts.

5. hidden feeder according to part specifications types, install component braid feeder correctly. When loading, the center of the part should be aligned with the pick center of the feeder.

6. Equipment condition check:

The main results are as follows: (1) The air pressure of the air compressor should meet the equipment requirements, generally 6 kgjf / cm2 ~ 7kgf / cm2.

(2) Check ensure that the guide rails mounting heads are within the movement range, the suction rack is automatically replaced around the library, there are no obstacles on the tray bracket.

After using the LED placement machine, the maintenance of the LED placement machine needs to be done well, so we need to do regular inspections.
