Functions and Tool Changing Skills of surface mount Sensors
Function of SMT sensor
The sensor of the SMT machine is an important part of the whole SMT machine. If each sensor does not assist each other, it can only rely on systems that cannot be assembLED and produced. What sensors does SMT mounter have? What does each sensor do? Let's look at the following.
1. Pressure sensor: mainly responsible for detecting and sensing air pressure. When we use surface mount components, the air cylinder and vacuum generator have certain requirements for air pressure. The pressure sensor plays an important role here. When the detection pressure is low, the staff will be immediately rEMInded to detect the pressure.
2 Position sensor: It can not only provide the position of PCB for SMT mounter system, but also detect PCB components in real time, and help our system assembly, so it has strICt requirements for work information
Circuit board

3. Image sensor: The sensor can provide the real-time working state of the smt assembly machine, collect various image signals required at this time, including the position of the PCB board, the size and model of the installation components, and then complete the assembly task through the universal seat system for analysis and processing.
4. Area sensor: mainly used for real-time detection of security problems. When we use SMT mounter, it is safe to work. The area sensor is usually installed in each mobile area to continue to detect the content information of the workspace
SMT mounter tool change prompt
The tip mounter blade is a common accessory in the tip mounter. We can use tools to enable us to better produce SMT parts to respond quickly and improve production efficiency. However, a tool is a consumable. Accumulated use will cause certain damage to itself. This time we need to change the knife after the operation, so how to change the knife? Let's see.
Replace the paper cutter of the same type
1. First, we must return to the origin, move the In tray to the fixed position, and then turn off the print head servo.
2. Use the manual handle to rotate the universal joint to CT25 °, and then turn off the air.
3. Loosen the screws of the fixing block and the adjusting block. First, remove the tool from the fixed blade, and then remove the tool from the moving side.
4. After reinstalling the paper cutter, rotate the adjusting screw on the left side of the paper cutter to move
Use the paper cutter to cut the paper up and down so that you can cut the paper (ordinary book paper), but
At the same time, it should not be too tight. The overlapping defect of the cutting blade * should be 1mm.
5. Tighten the clamping block screws and the positioning block of the positioning machine.
6. Use the manual handle to rotate the head back to the origin, and then turn on the air supply to return to the origin.
Change different types of tools.
1. Replace the paper cutter as described above
2. First, check the tool of the mounter to make sure it is open
Make sure the tape width is correct
3. Use the tool of the assembly machine to move up and down, and then check the operation
The tool path is appropriate.
4. Adjust the tool and push the length of the connecting rod in order to meet the following conditions: 2 and 3.
5. After adjusting the crank length, use the stop pin of the tool
The SMT machine should be adjusted accordingly and kept at a distance of 0.5mm as far as possible.
6. The above method is to adjust the paper cutter surface mounting machine on the
