Description

Technical Field

[0001] The invention belongs to the technical field of PCB circuit board processing, and in particular relates to a PCB circuit board fixing processing equipment. Background Art

[0002] PCB, also known as printed circuit board, is the provider of electrical connections for electronic components. It has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, improves the level of automation and production labor rate; and in order to facilitate the installation of PCB circuit boards on external devices, it is usually necessary to drill holes in the PCB circuit boards so that the PCB circuit boards can be installed on the external devices through external bolts.

[0003] The Chinese invention patent with the announcement number CN109819594B discloses a PCB circuit board fixing processing equipment, including a fixed bottom plate, a limiting cylinder is installed in the middle of the upper end of the fixed bottom plate, and a left-handed threaded rod and a right-handed threaded rod connected to each other are installed inside the limiting cylinder, and a moving block is installed in the middle of the left-handed threaded rod and the right-handed threaded rod respectively, and the upper end of the moving block is connected to the moving rod, and the upper end of the moving rod passes through the limiting groove provided in the middle of the upper end of the limiting cylinder to connect the limiting block, and the middle of the limiting block is connected to a rotating shaft through a bearing, and a lifting mechanism is installed on both sides of the upper end of the fixed bottom plate, and a lifting shaft is installed on the upper end of the lifting mechanism, and a fixed block is installed on the upper end of the lifting shaft, and a first screw rod is installed in the middle of the fixed block, and a first guide block is installed in the middle of the first screw rod, and a limiting plate is installed at the lower end of the first moving block. The above patent realizes the change of the distance between the U-shaped fixed plates, and ensures the double-sided processing of the PCB circuit board, and realizes the all-round processing of the PCB circuit board.

[0004] However, the above patent has the following shortcomings:

[0005] 1. The above patent drives the left-handed threaded rod and the right-handed threaded rod to rotate by a driving motor, thereby making the two moving blocks with different movement directions approach each other, so as to fix and clamp the PCB board through the U-shaped fixing plate. This clamping method can only clamp rectangular circuit boards. If the clamped circuit board is a special quadrilateral (for example, an isosceles trapezoid), the two U-shaped fixing plates will apply force to two points of the trapezoidal circuit board, thereby damaging the edge of the circuit board. In addition, the clamping method of the above patent will cause the tops of both ends of the circuit board to be unable to be processed due to the use of the U-shaped fixing plate.

[0006] 2. The above patent uses two lifting mechanisms to adjust the height of the two fixed blocks. This adjustment method is limited by the fact that the two lifting mechanisms must work synchronously. If one of the two lifting mechanisms descends due to a delay in starting, while the other does not, a fixed block will fall off the lifting shaft of the lifting mechanism that does not descend. Summary of the invention

[0007] The present invention provides a PCB circuit board fixing and processing equipment, aiming to solve the problem that the current clamping method can only clamp rectangular circuit boards. If the clamped circuit board is a special quadrilateral, the edge of the circuit board will be damaged due to the force applied by two U-shaped fixing plates to two points of the trapezoidal circuit board; and the current adjustment method is limited by the problem that two lifting mechanisms must work synchronously.
