Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a feeding frame for PCB board production. Background Art

[0002] When processing the PCB board, it is necessary to mount the surface of the PCB board. When moving it to the processing line, the loading frame can provide support for the PCB board, and the pushing structure can be used to push it out of the loading frame in sequence. The application number is CN202321901926.9, and a PCB board frame disclosed on March 15, 2024 includes a mounting frame, a support assembly, and a width adjustment assembly, wherein the support assembly includes a first support plate and a second support plate arranged at intervals, and the width adjustment assembly includes a synchronous belt and a plurality of screw rods, and a transmission wheel is fixed at one end of the screw rod so that the synchronous belt can drive the plurality of screw rods to rotate simultaneously. And the plurality of screw rods are arranged in parallel and are connected to the first support plate to drive the first support plate to translate, and then adjust the interval between the first support plate and the second support plate, so that the first support plate and the second support plate can support and clamp PCB boards of different widths. In addition, since the first support plate is directly connected to the plurality of screw rods, and the plurality of screw rods are driven simultaneously by the synchronous belt, it is ensured that the first support plate can move smoothly along the axial direction of the screw rod;

If the two sets of support plates are adjusted together, their movement needs to be controlled in sequence, which is inconvenient to adjust and it is difficult to maintain the consistency of the adjusted position.
