Hereinafter, referring to the related drawings, the control method for allowing the plate frame width adjusting device 100 to adjust the applicable width of the plate frame device 200 of the present invention will be described.

Referring to Figures 1 to 3, during the manufacturing process of the printed circuit board, a plurality of plate rack devices 200 will travel side by side at intervals at the same time (for example, travel in the lower left and upper right directions of FIG. 1), but only drawn in the figure A pallet device 200 is taken as an example. When the plate frame device 200 slides to the plate frame width adjustment device 100, the outer sides of the vertical frame rods 202 of the plate frame device 200 are respectively aligned with the hook structures 53 of the push hook modules 5 . Subsequently, the push hook modules 5 move laterally inwardly along the guide rails 3 toward the vertical frame rods 202, so that the hook structures 53 are pushed against the outer sides of the vertical frame rods 202, and the The vertical frame rods 202 slide inwardly along the horizontal frame rods 201 toward the blocking structures 203 until the vertical frame rods 202 abut against the blocking structures 203 and cannot continue to move. Since the separation distance between the vertical frame rods 202 of each pallet device 200 may be different before the width adjustment, the vertical frame rods 202 of each pallet device 200 are all pushed inward through the above steps When reaching the stopping structures 203, the vertical frame rods 202 of each plate frame device 200 are set to the state of the minimum distance, so that the vertical frames can be further enlarged according to the width of the printed circuit board. The distance between the rods 202.

4 to 6, after the completion of the foregoing steps, the hook structures 53 will be driven by the hook drive units 54 to rotate around the shafts 52, so that the hook structures 53 The hooks 532 pivot upward and move to a position adjacent to the protruding portion 205 of the latch (as shown in FIG. 4). Subsequently, the push hook modules 5 will be controlled to move along the guide rails 3 away from the blocking structures 203, so that the hook portions 532 of the hook structures 53 are engaged in the cards respectively. The inner side of the convex portion 205 can be pulled to slide the vertical frame rods 202 away from the blocking structures 203 to a predetermined position (as shown in FIG. 5 and FIG. 6), so that the vertical frame can be moved to a predetermined position (as shown in FIG. 5 and FIG. 6). The spacing distance of the rods 202 is adjusted to match the width of the printed circuit board to be clamped, and the adjustment setting of the applicable width of the vertical frame rods 202 is completed.

In the aforementioned adjustment process, the main actions of the push-pull devices 1 only include the push-hook modules 5 pushing the longitudinal frame rod 202 inward, the hook structures 53 pivoting upward, and the push-hook modules 5 The three steps of pulling the vertical frame rods 202 outwards are simple in execution flow, and can be driven by the guide rail drive unit 4 and the hook drive unit 54 to precisely control the operating stroke and operating speed, so that the operating speed can be controlled in a short period of time. The suitable width adjustment of each pallet device 200 can be accurately and effectively completed within a time, which is beneficial to the improvement of production efficiency, and therefore can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
