What should I do if the Siemens placement machine feeder throws material?

In the SMT production process, feeder throwing material is a common issue. Today we analyze some problems of Siemens feeder throwing materials.

1. The problem of the nozzle of Siemens placement machine:
The deformation, clogging and damage of the suction nozzle will cause insufficient air pressure and air leakage, which will cause the suction of the material to be unavailable, the material is not taken correctly, or the material cannot be identified and the material is thrown;
Solution: replace the nozzle
E.g: 
Siemens 901 SMT Nozzle - Part Number: 00322603, 0.95 mm x 1.4 mm
Siemens 902 SMT Nozzle - Part Number: 00348186, 0.95 mm x 0.5 mm
Siemens 904 SMT Nozzle - Part Number: 00322602, 1.2 mm x 1.8 mm
Siemens 906 SMT Nozzle - Part Number: 00345031, 0.5 mm x 0.35 mm
Siemens 925 SMT Nozzle - Part Number: 00333652, 0.43 mm x 0.63 mm

2. The problem of the recognition system of Siemens placement machine accessories:
When there are dirt or debris on the visual or laser lens that interfere with the identification, or the identification light source is not selected properly, the intensity grayscale is not enough, and the identification system has been broken, the material throwing rate will be high. What we need to do is to clean the surface of the recognition system frequently to keep it clean. If the strength and grayscale are not enough, we must adjust ourselves. If the recognition system is broken, we must replace the recognition system components;
Solution: replace the identification system parts

3. The problem of the location of Siemens placement machine parts:
If the material is not in the center of the material or the deviation caused by the incorrect material height, the material is incorrect, etc. will be discarded as invalid material by the recognition system, causing waste, so we must adjust the material when we work. Material location
Solution: adjust the picking position

4. Vacuum problem of Siemens placement machine:
When the air pressure is insufficient, the vacuum tracheal channel is not smooth, there is a blockage of foreign objects or the air pressure is insufficient due to vacuum leaks, etc. can cause the material to be unavailable or fall after being picked up on the way to the Siemens placement machine accessories. The waste of throwing material, therefore, we must adjust the air pressure to the required air pressure of the equipment. For the leakage problem, we must repair it in time, and the blockage caused must be cleaned up in time.
Solution: Adjust the air pressure to meet the required air pressure value of the equipment; clear the blockage

How does the nozzle of Samsung placement machine correspond to the material selection

Image
Regarding how to choose the material of the Samsung SMT nozzle , the most encountered problem is that many technicians and customers do not know the component selection corresponding to the Samsung nozzle. Today I will briefly introduce how the material of the Samsung SMT nozzle corresponds to the material Selection. Take the nozzle of Samsung Chip Mounter CP-45NEO / CP-45FV as an example: Samsung CP-45NEO Nozzle Assembly: CN020,CN030,CN040,CN065,CN110,CN140,CN220,CN400, CN400N ,CN750, CN1100 Samsung CP-45FV Nozzle Assembly: TN020, TN030 , TN040 , TN065 , TN140 , TN220 , TN400 , TN750 , TN1100 Suction hole diameter: 0.18mm, 0.28mm, 0.38mm, 0.65mm, 1.4mm, 2.2mm, 4.0mm, 7.5mm, 11mm. Selection principle of suction nozzle: 1. The diameter of the selected nozzle hole cannot be larger than the minimum size of the component. 2. The diameter of the selected nozzle hole should not be too small than the minimum size of the component, and the general proportion is 1:1.2-1.7, which is ...

Solution to the dropping of nozzle of JUKI mounter ke-2050

Image
Juki KE-2050 nozzle is not directly connected to the placement machine, there is actually another part connected between them-nozzle holder. We installed the nozzle of the Juki placement machine KE-2050 on the nozzle holder, and then installed the nozzle holder on the placement machine. This will cause a problem that the nozzle is easily separated from the nozzle holder while playing. The reasons for the above problems may be as follows, we analyze them one by one: 1. The Juki KE-2050 nozzle holder with the nozzle is worn out during use and the size becomes smaller, which does not match the nozzle holder. At this time, replace the new nozzle holder. Of course, this is only a temporary solution to the problem, and the situation needs further analysis. 2. It is not the problem of the entire nozzle holder, but the inner gasket is worn or dropped in production, and it is sufficient to replace or reinstall a gasket. 3. The cause of the brake pads, there should be a phenomenon of jitter in...

Why is the black material commonly used for the nozzle of the placement machine?

Image
The SMT placement equipment has now become the mark of our fully automatic production line, and the SMT placement equipment can accurately and quickly place components all rely on the role of the nozzle. When we use the nozzle of the placement machine, we will definitely find that the nozzles are all black. Why should we use black nozzles? To understand this problem, we must first know what role the nozzle has? The nozzle of the placement machine is not only the key part of the placement machine to pick and place the sucked component, but also the background when the camera of the optical vision system takes a picture. It mainly uses the suction effect of the vacuum to suck the component, and Use blowing to put the components adsorbed on the nozzle to the coordinate position of the circuit board. Almost every nozzle will have a reflective background, which is mainly to have a good background when the image is taken, so that the target information can be accurately highlighted during ...
