[0002] PCB, Chinese name for printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. PCB is required for the production of LED light boards, makeup mirrors, and advertising machines. PCB is also often used in chip component production equipment or semiconductor light emitting diodes, LED backlight sources and other fields.
[0003] After the automatic placement process, the PCB circuit board needs to be transferred to the reflow soldering process. A transfer machine is used in the transfer process. The PCB transfer machine can realize the direct connection between two adjacent production lines with limited space in the processing workshop, so that the two production lines can be placed in parallel to reduce the footprint of the equipment. The transfer machine can also keep the position of electronic components on the PCB board from shifting, thereby improving work efficiency.
[0004] However, the existing transfer machines can only be used for products of the same size, and have a narrow scope of application. There is a problem that the transfer width cannot be adjusted according to circuit boards of different widths. Utility Model Content

[0008] Furthermore, the horizontal displacement transmission mechanism includes support plates fixedly arranged at both ends of the workbench, a second guide rod is fixedly connected between the two support plates, a screw is rotatably arranged between the two support plates, a screw motor is arranged on the workbench to drive the screw to rotate, the base plate is threadedly connected to the screw, and the base plate is slidably sleeved on the second guide rod.

Stepper motors for driving the rotating wheels to rotate are installed on the first mounting plate and the second mounting plate.
[0010] Furthermore, the first mounting plate and the second mounting plate are both provided with limit plates, and the limit plates are arranged parallel to and above the belt.
[0011] Furthermore, both sides of the protective shell are provided with inlet and outlet ports.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] The screw rod is driven to rotate by the pitch-adjusting motor to drive the second mounting plate to move away from or close to the first mounting plate, thereby adjusting the distance between the first mounting plate and the second mounting plate, so that PCB boards of different sizes can be carried. After the PCB boards are transported to the belt transmission mechanism, the horizontal displacement transmission mechanism drives the bottom plate to move, and the PCB boards are transplanted to another production line. The utility model improves the applicable range of the size of the transplanted products, and can be adjusted according to needs to adapt to PCB workpieces of different widths.
