DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0023] like Figure 1-Figure 4 ,

[0024] It includes a lower template 1, a support frame 11 is installed on the top of the lower template 1, and a support frame 2 12 is installed on the bottom of the lower template 1. The support frame 11 is used to support and install the hydraulic cylinder 23. The lower template 1, the support frame 11 and the support frame 2 12 are provided with a waste discharge mechanism 2, which is convenient for discharging waste when punching and cutting auxiliary materials of flexible circuit boards;

[0025] The waste discharge mechanism 2 includes a die plate 21 and a discharge port 22. The die plate 21 is assembled to the upper end of the lower template 1. A blade 211 is engraved on the upper end of the die plate 21 by an engraving machine. The auxiliary materials of the flexible circuit board are punched through the upper end of the die plate 21. The inner wall of the lower template 1 begins to have a discharge port 22. The waste after the auxiliary materials of the flexible circuit board are punched falls into the discharge port 22 through the middle of the die plate 21, and then falls into the receiving box 29 through the discharge port 22. The discharge port 22 is set directly below the die plate 21. The inner side surface of the discharge port 22 is larger than the inner side surface of the die plate 21. The top of the die plate 21 is provided with a blade 211 with an angle of 40 degrees. The blade 211 is straight inside and oblique outside.

[0026] A hydraulic cylinder 23 is installed on the top of the support frame 11, and the upper template 24 is driven to rise and fall by the hydraulic cylinder 23. The output end of the hydraulic cylinder 23 is connected to the upper template 24, and the upper template 24 supports the limit plate 241 and the push block 25 to rise and fall. The bottom of both ends of the upper template 24 is equipped with a limit plate 241. The limit plate 241 descends to limit the downward pressure of the soft circuit board auxiliary material to prevent the soft circuit board auxiliary material from deviating during stamping. A push block 25 is also installed at the bottom of the upper template 24, and the push block 25 pushes down the soft circuit board auxiliary material, and then the blade 211 at the top of the die steel plate 21 is used for punching. The waste material after punching falls to the inner side of the die steel plate 21, and the push block 25 continues to descend and is inserted into the die steel plate 21 to push the waste material in the die steel plate 21 down and out. The push block 25 is arranged just above the die steel plate 21, and the volume of the push block 25 is smaller than the volume of the die steel plate 21.

[0027] A hydraulic cylinder 26 is installed at the bottom of the lower template 1, and the hydraulic cylinder 26 drives the support plate 27 to rise to support one end of the soft circuit board auxiliary material, thereby increasing the stability of the soft circuit board auxiliary material support stamping. The output end of the hydraulic cylinder 26 is connected to the support plate 27. A hydraulic cylinder 3 261 is also installed at the bottom of the lower template 1. The hydraulic cylinder 3 261 drives the support plate 271 to rise to support the other end of the soft circuit board auxiliary material, thereby increasing the stability of the soft circuit board auxiliary material support stamping. The output end of the hydraulic cylinder 3 261 is connected to the support plate 271. A limiting plate 28 is installed at the bottom of the support frame 2 12. The limiting plate 28 is used to limit the docking material box 29. The inner side of the limiting plate 28 slides and is inserted into the material receiving box 29, and the cutting waste falling from the discharge port 22 is received through the material receiving box 29.

[0028] The working principle of the utility model is as follows: the soft circuit board auxiliary material is placed on the upper end of the die cutter steel plate 21, and the hydraulic cylinder 26 drives the support plate 1 27 to rise to support one end of the soft circuit board auxiliary material, thereby increasing the stability of the soft circuit board auxiliary material support stamping, and the hydraulic cylinder 3 261 drives the support plate 2 271 to rise to support the other end of the soft circuit board auxiliary material, thereby increasing the stability of the soft circuit board auxiliary material support stamping, the hydraulic cylinder 23 pushes down the upper template 24, and the upper template 24 drives the limit plate 1 241 and the push block 25 to push down, and the soft circuit board auxiliary material is pushed down by the push block 25, and then the blade 211 at the top of the die cutter steel plate 21 is used for punching, and the waste material after punching falls to the inner side of the die cutter steel plate 21, and the push block 2 5 continues to descend and insert into the die steel plate 21, pushes down the waste in the die steel plate 21 and drops it out, and at the same time, the limit plate 1 241 descends to limit the soft circuit board auxiliary material to prevent the soft circuit board auxiliary material from shifting during stamping. After the soft circuit board auxiliary material is stamped, the support plate 1 27 and the support plate 2 271 descend without affecting the downward movement of the limit plate 1 241, and the push block 25 pushes the waste down and drops it into the receiving box 29 through the discharge port 22 for placement, so that the soft circuit board auxiliary material can be automatically discharged after stamping. When the receiving box 29 is full, it can be pulled out and replaced, so that the die cutter can automatically discharge the waste, and there is no need for personnel to manually clean the waste on the mold surface every time they work, thereby improving work efficiency and saving costs.

In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
