[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example

[0035] Reference Figures 1 to 8, is an embodiment of the utility model, which provides a plate support structure of a pad window opening machine, wherein the support assembly 100 includes a support plate 101, and the support plate 101 is placed on the working platform of the window opening machine for fixing the PCB board;

[0036] The limiting assembly 200 is composed of a clamping member 201 and an expansion bladder 203. The clamping member 201 is placed on the supporting plate 101 and is used to clamp the reserved hole of the PCB board.

[0037] The clamping member 201 can be closed by the contraction of the expansion bladder 203, and the clamping member 201 can also be expanded by the expansion of the expansion bladder 203;

[0038] The contraction and expansion states of the expansion bladder 203 control the state switching of the clamping member 201. When clamping the inner diameter of the reserved hole of the PCB board, the clamping member 201 in the closed state is first smaller than the reserved hole diameter of the PCB board, which is convenient for quick pre-positioning of the PCB board before fixing. Then, the reserved hole of the PCB board is clamped by the clamping member 201 in the expanded state, so that the PCB board can be quickly fixed before the window is opened. Similarly, the reverse operation can quickly take out the PCB board with the window opened, realizing a high-efficiency PCB board window opening operation.

[0039] like Figure 1 , Figure 2 , Figure 8 As shown, specifically, the clamping member 201 has an arc-shaped movable path e with the rotation support point f as the fulcrum, the clamping member 201 is arranged on the pad 202a of the support seat 202, the support seat 202 is arranged in the assembly hole 101b opened in the support plate 101, and a plurality of assembly holes 101b are arranged by design, so that such a support plate 101 can meet different types of PCB boards, and at the same time, the four corners of the support plate 101 are also provided with fixing recesses 101a, and the support plate 101 is fixed on the window opening workbench by screws or some other fixing members;

[0040] The supporting plate 101 hydrogel tube is also provided with a circuitous adapting groove 101c, and a thinner buffer pad 102 is provided in the adapting groove 101c. The buffer pad 102 can be made of a material that is elastic and quickly restored, such as silicone, and has a thickness of 2-3mm to prevent the problem of the PCB board being broken due to excessive buffer space. A rigid pad 103 needs to be placed on the buffer pad 102 to support the PCB board. This setting is to provide a certain buffering effect when the saw blade cutting machine is cutting the PCB board;

[0041] like Figure 2-Figure 5As shown, the clamping member 201 is composed of a guide piece 201a, an upper clamping piece 201b, a middle clamping piece 201c, a lower clamping piece 201d and a supporting piece 201g. In the retracted state, the guide piece 201a passes through the reserved hole of the PCB board, and in the expanded state, the upper clamping piece 201b, the middle clamping piece 201c and the lower clamping piece 201d are used to squeeze the inner wall of the reserved hole of the PCB board, so that the positioning, clamping and removal of the PCB board are very convenient and fast, the window opening efficiency of the PCB board is improved, and the coating on the surface of the PCB board can be prevented from being scratched;

[0042] The support sheet 201g is used to switch between the two states of the clamping member 201 and provide support and fixed rotation support point f. The upper clamping member 201b, the middle clamping member 201c and the lower clamping member 201d are all provided with damping sleeves. In addition, there is an arc between the upper clamping member 201b and the middle clamping member 201c, and there is also an arc between the middle clamping member 201c and the lower clamping member 201d. The expansion capsule 203 can be connected to the clamping member 201. The support sheet 201g can be set as a rotation support point f with a fulcrum to support the clamping member 201 to rotate within the range of the arc-shaped active path e. At this time, the closed and unfolded states are achieved by the contraction and expansion of the expansion capsule 203. The various groups of the clamping member 201 can also use elastic materials. The rotation support point f is a virtual fulcrum, which is achieved by the elastic deformation of each group of the pieces and the contraction and expansion of the expansion capsule 203. The switching between the closed and unfolded states has many such permutations and combinations, so they are not repeated here.

[0043] like Figure 6-Figure 7 As shown, in order to drive the expansion and contraction of the expansion bladder 203 and to achieve this in a simple manner, the connection point of the expansion bladder 203 is connected to the conduit 205 through a connector 204, and the conduit 205 can be connected to a driving member such as an air pump or an oil pump, wherein the internal medium of the expansion bladder 203 can be a material with good fluidity such as air or oil, and the effect to be achieved is to be able to quickly respond to the clamping of the PCB board by the clamping member 201.
