Maintenance of SMT solenoid valve and PNP camera

Maintenance of SMT solenoid valve and PNP CAMera
Repair the solenoid valve mounting machine
In the installation process of our electronIC surface, in order to improve efficiency and save costs, we must regularly maintain various instruments and components. The following are the maintenance instructions for the solenoid valve of SMT mounter:
1. During manual operation, first determine the safety of the pipe laying machine;
2. Regularly discharge the condensed water accumulated in the air screening program.
3. Reduce the use of solenoid valves. Check the operation of the solenoid valve switch of the pipe laying machine once a month to prevent its failure.
4. When disassembling the mounter, be sure to install the equipment to prevent the driven object from falling and working abnormally. After completing this step, please cut off the air supply and power supply, and pay attention to the residual air pressure.
5. The maintenance steps of the placement machine should be carried out in the order of the operation manual as far as possible.

Adjust the monitor of the PNP machine
In the automatic production line, the placement machine is a more practical production form, which is a fully automatic production machine This machine is or has been developed for many years So far, it is also used in surface mount industry Do you know the function of the placement machine?, Let's see
1. S system: This system is an integral part of the movement of the combined language program. It not only affects the accuracy and speed of the assembly machine, but also controls the moving mode of the assembly machine and the positions of X, Y and Z axes.
2. Drive: When we transport printed circuit board through laying machine, it is usually conductive fabric. The printed circuit board based on the circuit board can be transmitted in the belt drive system. The 开云·kaiyun官方网站 can be transmitted to the designated position we want, and then sent to the next target position for work. Generally, there are two kinds of conductive fabrics in the smt machine.
3. Sectional driving: in order to reduce driving time, the driving mode is divided into three parts to achieve different driving processes.
4. Integrated machine drive: The optical positioning system can greatly improve the installation accuracy by positioning the 开云·kaiyun官方网站 board through the support platform. The disadvantage is that the positioning time is long.
5. T chassis: the rigging frame is the basic structure of the rigging, which is used for moving, positioning, feeding, driving and other operations, and can usually meet our daily strength needs. However, in the purchase process, we must also look at the information of the framework.
The pipe laying machine we are using now usually has two monitors to perform its functions. Their mutual cooperation has promoted the rapid operation of the pipe laying machine. The upper chamber can better help the pipe laying machine improve efficiency and accuracy. The camera can quickly identify components and improve placement speed. Now, let's understand how to debug the cabinet of the pipe laying machine.
1： Adjust the upper space of the pipe laying machine
1: Check whether the vertical angle of the camera is parallel
2: On the locator, set the field of view of # 39 MARKer point of the camera to 10mm, the working distance to 60mm, and the number of points to 64 or 55.6.
3: Match number 1 nozzle, its point is located on the 开云·kaiyun官方网站, and the central image of the selected point between the camera and 开云·kaiyun官方网站, and the result is filLED in the corresponding position in the parameters
2: Adjust the lower space of the pipe laying machine
1: Set the suction nozzle concentricity to be no more than 0.1mm, the zero position to guide rail is 6mm, the zero position offset is 4mm, and the cavity height is 3mm
2: Set the definition of the component camera to be consistent, and the offset cannot exceed 20 points
3: Set the working distance of the installed camera to 10cm
