Of course, the number of material racks 201 is not limited. It can be 2, 3 or 4 or other numbers of material racks 201 to improve the feeding efficiency. In addition, in the present invention, the protective mesh material plate 203 is a flat material plate, and a plurality of protective nets are arranged on the material plate, and the protective nets are arranged in an array. When actually feeding, the protective mesh material plate 203 is manually placed on the material rack 201, and the material plates are accumulated and stacked one layer at a time for the manipulator 202 to grab.

[0020] In the embodiment of the present invention, the aforementioned manipulator 202 is slidably arranged on a slide rail frame 204, a sliding cylinder is arranged on one side of the slide rail frame 204, and the output end of the sliding cylinder is connected to the aforementioned manipulator 202. By arranging the manipulator 202 on the slide rail frame 204 and providing momentum by the sliding cylinder, the manipulator 202 can slide horizontally on the slide rail frame 204. In the embodiment of the present invention, the slide rail frame 204 is arranged above the material rack 201 and remains parallel to the material rack 201, so that the manipulator 202 can slide to the material rack 201 to be punched to grab the protective mesh material plate 203. The provision of multiple material racks 201 and slide rail frames 204 can ensure the continuous operation of the punching die mechanism 3. When the protective mesh material plate 203 on a material rack 201 is completely grabbed by the manipulator 202, the manipulator 202 can be moved to the top of another material rack 201 to avoid the situation where the manipulator 202 grabs empty materials. When the robot 202 is operating on another material rack 201, the operator can add the protective mesh material plate 203 to the previous empty material rack, thereby improving the operating efficiency.

[0021] In the embodiment of the present invention, the aforementioned feeding mechanism 2 also includes a waste box 205. When the aforementioned protective mesh material plate 203 completes the die punching operation of the entire plate, the robot 202 will transfer the material plate to the waste box 205 to realize waste collection.

[0022] In the embodiment of the present invention, refer to Figure 3 , Figure 4 and Figure 5 The aforementioned die mechanism 3 includes a die frame 301, which is used to receive the protective mesh material plate 203 grasped by the aforementioned manipulator 202, and a pressing plate 302 is arranged above the die frame 301, which is used to provide a pressing force for the aforementioned protective mesh material plate 203 to prevent it from deflecting on the die frame 301 and affecting the die precision. In addition, the pressing plate 302 is also provided with a protective mesh die hole 303 aligned with the protective mesh on the aforementioned protective mesh material plate 203.

[0023] A punch 304 is provided below the aforementioned die frame 301. In the embodiment of the present invention, a plurality of punches 304 are provided, one punch 304 corresponds to one protective net die hole 303, and the punches 304 are arranged in a horizontal array. One end of each punch 304 is connected to a die cylinder 305. In the embodiment of the present invention, when the die is in operation, each punch 304 operates intermittently, that is, when one punch 304 completes the die upward, the next punch 304 continues to operate. Of course, each punch 304 can also be set to operate simultaneously.

[0024] The punch 304 uses the driving force provided by the aforementioned punch cylinder 305 to punch the lower surface of the aforementioned protective net material plate 203 upwards, and since the aforementioned pressure plate 302 is provided with a protective net die hole 303, the protective net can be punched out from the aforementioned protective net die hole 303, thereby completing the punching operation of a single protective net.

[0025] In the embodiment of the present invention, the die frame 301 is mounted on a sliding track 306, a slider 307 is provided on the sliding track 306, one end of the slider is connected to a driving motor, and a slide rod 307 is passed through the middle of the slider 307. With the driving force provided by the driving motor, the die frame 301 can slide on the sliding track 306. In the embodiment of the present invention, the slide rail frame 204 is perpendicular to the sliding track 306. Specifically, the non-die operating end of the sliding track 306 is close to the end of the aforementioned sliding rail frame 204 away from the aforementioned material frame 201. Therefore, when the aforementioned manipulator 202 grabs the protective mesh material plate 203, the die frame 301 is driven by the driving motor to move to the non-die operating end and approach the manipulator 202. The manipulator 202 can place the grabbed protective mesh material plate 203 on the die frame 301, and then the die frame 301 moves to the die operating end after receiving the protective mesh material plate 203.
