The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a multi-layer circuit board pressing machine of the utility model comprises a positioning plate 1, a positioning hole 2 matching the circuit board is provided in the middle of the positioning plate 1, a bearing plate 9 blocking the lower end opening of the positioning hole 2 is installed on the bottom surface of the positioning plate 1, a support plate 3 is provided in the positioning hole 2, grooves 12 are provided at both ends of the positioning hole 2, and limiting plates 4 movably connected to the support plate 3 are provided in the grooves 12, the upper ends of the limiting plates 4 are bent inwards to form a pull-up portion 5, and a pressing plate 6 for pressing the circuit board downward is provided between the limiting plates 4, and the pull-up portions 5 are extended to the top of the pressing plate 6.

[0024] In this embodiment, a mounting hole is provided at the lower end of the limit plate 4, a spring 11 is provided in the mounting hole, the outermost circle of the spring 11 is installed on the inner circle surface of the mounting hole, an axle rod 10 is installed in the innermost circle of the spring 11, and one end of the axle rod 10 is installed on the end surface of the support plate 3.

[0025] In this embodiment, a plurality of fixing brackets 8 are installed outside the cylinder 7 , and the other ends of the fixing brackets 8 are all installed on the positioning plate 1 .

[0026] In this embodiment, fixing holes are provided on the four corners of the positioning plate 1, and screws can pass through the fixing holes to fix the positioning plate on any desktop.

[0027] In this embodiment, the length and width of the pressing plate 6 match the length and width of the positioning opening 2, so that the pressing plate can just enter the positioning opening and just completely contact the circuit board, thereby fully completing the pressing operation of the circuit board.

[0028] In this embodiment, the length and width of the support plate 3 match the length and width of the positioning opening 2 , the bottom surface of the support plate 3 is arranged to abut against the top surface of the load-bearing plate, and the outer side surface of the support plate 3 is arranged to contact the inner side surface of the positioning opening 2 .

[0029] In this embodiment, the mainspring 11 is in a twisted state, so after the support plate is moved out of the positioning opening, the reverse twisting of the mainspring can drive the shaft and the support plate to rotate.

[0030] In this embodiment, the inner side surface of the limiting plate 4 is flush with the inner side surface of the positioning opening 2 so as not to affect the up and down movement of the supporting plate, thereby avoiding obstruction of the movement of the supporting plate.

[0031] When in use, the multi-layer circuit board can be directly placed in the positioning opening, and the circuit board can be positioned front, back, left, and right through the positioning opening. After positioning, the cylinder can be started to extend the piston rod of the cylinder and drive the pressing plate downward, so that the pressing plate moves downward along the limiting plate until it enters the positioning opening and presses the multi-layer circuit board tightly.

[0032] After the pressing is completed, the cylinder can be started again to retract the piston rod of the cylinder and drive the pressing plate to move upward. After the pressing plate moves to a certain height, the pressing plate can contact the upper pull-up part and drive the upper pull-up part and the limit plate to move upward. The movement of the limit plate drives the pallet, and the pallet can push the circuit board upward. After the pallet moves to the outside, the pallet will lose the obstruction of the positioning port, and the torsion of the spring can drive the shaft rod and the pallet to tilt to one side, so that the circuit board can automatically slide along the inclined pallet, which greatly facilitates the board retrieval operation.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
