Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, and in particular to a PCB board loading and mounting mechanism. Background Technology

[0002] A PCB (Printed Circuit Board) is a type of electronic product that serves as a carrier for connecting multiple electronic components in series.

[0003] Given the high demand for consumer electronics products, consumers have higher requirements for product updates and iterations. Therefore, companies need to shorten product changeover times, reduce production costs, and improve manufacturing precision. Consequently, automated production lines have rapidly replaced manual labor.

[0004] In PCB manufacturing, components, often irregularly shaped, need to be installed. Existing PCB component installation equipment includes a base plate, a mounting frame, X-axis, Y-axis, and Z-axis motion mechanisms, a gripper, and a positioning mechanism mounted on the base plate for positioning the base plate. The mounting frame is mounted on the base plate, and the X-axis, Y-axis, and Z-axis motion mechanisms, respectively, have degrees of freedom in the X, Y, and Z directions. The gripper, mounted on the Z-axis motion mechanism, is used to drive the gripper to a suitable position to pick up and unload the PCB. Existing installation equipment is station-type, with PCB loading and unloading achieved solely through the gripper. This makes it impossible to connect with the conveyor lines on the upstream and downstream production lines of the installation equipment, resulting in production pauses and low efficiency. Utility Model Content

The mounting frame is connected to both ends of the base plate in the Y direction. The base plate is provided with a positioning mechanism for clamping the PCB board. One end of the base plate in the Y direction is provided with a feeding frame, and the other end of the base plate in the Y direction is provided with a discharging frame. One end of the feeding frame and the discharging frame are connected to the positioning mechanism, and the other end of the feeding frame and the discharging frame extend to the outer side of the base plate. The X-axis motion mechanism is mounted on the mounting frame, the Y-axis motion mechanism is adapted to the X-axis motion mechanism, the Z-axis motion mechanism is adapted to the Y-axis motion mechanism, and the end of the Z-axis motion mechanism is provided with a gripper.

[0007] Preferably, both the feeding rack and the discharging rack include two support plates spaced apart in the X direction and at least one guide rod connected between the two support plates. One end of each support plate is connected to the positioning mechanism, and the other end of each support plate extends along the Y direction to the outside of the base plate.

[0008] Preferably, the X-axis motion mechanism includes a first single-axis driver mounted on one of the mounting brackets, a first guide rail mounted on the other mounting bracket, and a first motor for outputting power to the first single-axis driver. The Y-axis motion mechanism is slidably connected to the first single-axis driver and the first guide rail.

The pneumatic gripper is driven to a gripper, and the third slider is slidably connected to the Y-axis motion mechanism.

[0012] Preferably, the mounting frame includes uprights connected to both ends of the base plate in the X direction and a crossbar connected between the tops of the two uprights. The crossbar is suspended from the base plate to form a gap, and the feeding rack and the discharging rack extend through the gap.

[0013] Preferably, the gripper is a suction cup or a mechanical finger.

[0014] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0015] I. This utility model adds a feeding rack and a discharging rack to the base plate. The feeding rack can be connected to the conveyor belt on the upper production line of the equipment, and the discharging rack can be connected to the conveyor belt on the lower production line of the equipment. The mounting mechanism can be directly embedded into the production line, so that the PCB can quickly enter the mounting mechanism for assembly. It is well connected with the production line cycle and greatly improves production efficiency.

[0016] 2. The PCB board loading and mounting mechanism achieves movement in three directions through three single-axis drives, and each is powered by a motor, enabling high-precision movement in a Cartesian coordinate system space. The single-axis drives also have advantages such as easy installation, high strength, and compact structure.

[0017] Third, the first and second connecting plates of the Y-axis motion mechanism on the PCB board loading and mounting mechanism are both equipped with triangular ribs, which can improve the overall tensile strength and reduce the vibration generated during the movement.
