[0021] In this embodiment, the feeding structure 3 is mainly responsible for conveying the material to the appropriate position. When working, the material box 310 is connected to the movable frame 305 by fastening bolts 309. First, two material boxes 310 are installed on the movable frame 305. After the installation is completed, one of the material boxes 310 is installed above the conveyor belt assembly 302.

When the conveyor belt assembly 302 is started, it drives a workpiece forward, and the workpieces in the material box 310 fall down one by one. When there are no workpieces in the material box 310 above the conveyor belt assembly 302, the feeding drive motor 307 is started to drive the incomplete gear 306 to rotate. The characteristics will cause the movable frame 305 to make reciprocating linear motion in the slide groove of the movable groove 3041, and the incomplete gear 306 rotates half a circle. The movable frame 305 drives the material box 310 above the conveyor belt assembly 302 to move to one side, and moves another material box 310 above the conveyor belt assembly 302 to facilitate the replacement of the used material box 310, and then install another material box 310 full of workpieces above the movable frame 305. When the material box 310 above the conveyor belt assembly 302 is used up, the incomplete gear 306 drives the movable frame 305 to move in the opposite direction, and so on and so forth, which is convenient for continuous loading.

[0022] The upper and lower inner walls of the movable groove 3041 are both provided with sliding grooves, and the outer wall of the movable frame 305 is slidably connected to the inner wall of the sliding grooves.

[0023] The bottom of the material box 310 abuts against the top outer wall of the feeding sealing bottom plate 303 , and the feeding sealing bottom plate 303 is flush with the height of the conveyor belt assembly 302 .

[0027] Example 2: See also Figure 4-Figure 7 As shown, based on Example 1, the present invention provides a technical solution: the material moving structure 4 includes a vertical lifting component 401, and a horizontal moving rail 402 is provided on the front side of the vertical lifting component 401. The inner wall of the horizontal moving rail 402 is rotatably connected to the material moving screw 403, and the inner wall of the horizontal moving rail 402 is slidably connected to the moving block 404. The inner wall of the moving block 404 is threadedly connected to the outer wall of the material moving screw 403. There are two moving blocks 404. The outer wall of one side of the moving block 404 is fixedly connected to a connecting plate 405, and the bottom outer wall of the connecting plate 405 is fixedly connected to a clamping robot 406.

[0028] Among them, the outer wall of one side of the horizontal moving rail 402 is rotatably connected to the driven gear 407 and the driving half gear 408. The upper and lower sides of the driven gear 407 are provided with the driving half gear 408. The two driving half gears 408 are alternately engaged with the driven gear 407. One end of the material moving screw 403 is connected to the driven gear 407. The inner wall of the horizontal moving rail 402 is fixedly connected to the material moving motor, and the output shaft of the material moving motor is connected to the driving half gear 408.

[0029] In this embodiment, the function of the material transfer structure 4 is to move the conveyed material to the punching position. The vertical lifting assembly 401 can drive the horizontal moving rail 402 to perform vertical lifting movement to adjust the height to adapt to different work requirements. The material transfer motor is started, and its output shaft drives the active half gear 408 to rotate. The two active half gears 408 alternately engage with the driven gear 407, thereby driving the driven gear 407 to rotate alternately in forward and reverse directions. The driven gear 407 is connected to the material transfer screw 403, so that the material transfer screw 403 also rotates alternately in forward and reverse directions, driving the two clamping manipulators 406 to move to one side at the same time. When one of the clamping manipulators 406 moves to the edge of the operating table 2 to clamp the workpiece on the conveyor belt assembly 302, the other clamping manipulator 406 moves to the middle of the operating table 2 and places the workpiece above the punching hole. The two clamping manipulators 406 alternately place the workpiece.

[0030] Example 3: See also Figure 1-Figure 2 and Figure 8 As shown, based on Example 1 and Example 2, the present invention provides a technical solution: a positioning structure 5, comprising a movable groove 501 opened on the operating table 2, the movable groove 501 is symmetrically opened on both sides of the punching hole, the inner wall of the movable groove 501 is rotatably connected to the positioning screw 502, the inner walls of the two movable grooves 501 are slidably connected to the positioning blocks 504, the positioning blocks 504 are symmetrically arranged on both sides of the punching hole, the inner wall of the positioning block 504 is threadedly connected to the outer wall of the positioning screw 502, and the positioning block 504 contacts the thread on the positioning screw 502 in the opposite direction.

[0031] The positioning screw rod 502 is driven by the positioning drive motor 503 . When the two positioning blocks 504 move toward the middle at the same time, the outer walls of the positioning blocks 504 abut against the outer wall of the workpiece.

[0032] In this embodiment, the positioning structure 5 is used to accurately position the material placed on the operating table 2. The positioning drive motor 503 is activated, driving the positioning screw 502 to rotate. Because the positioning blocks 504 contact the threads on the positioning screw 502 in opposite directions and the positioning blocks 504 slide within the movable groove 501, the two positioning blocks 504 will move toward the center simultaneously. When the outer walls of the positioning blocks 504 abut the outer walls of the workpiece, the workpiece is positioned, ensuring that the workpiece is accurately positioned during the stamping process, thereby ensuring stamping quality.

[0033] Working principle: The feeding structure 3 is mainly responsible for conveying the material to the appropriate position. When working, the material box 310 is connected to the movable frame 305 by fastening bolts 309. First, two material boxes 310 are installed on the movable frame 305. After the installation is completed, one of the material boxes 310 is installed above the conveyor belt assembly 302. There is a distance of one workpiece between the material box 310 and the conveyor belt assembly 302. When the conveyor belt assembly 302 is started, it drives a workpiece to move forward, and the workpieces in the material box 310 fall down one by one. When there is no workpiece in the material box 310 above the conveyor belt assembly 302, the feeding drive motor 307 is started to drive the incomplete gear 306 to rotate. The characteristics of the movable frame 305 will make a reciprocating linear motion in the slide of the movable groove 3041, and the incomplete gear 306 will rotate half a circle. The movable frame 305 drives the material box 310 above the conveyor belt assembly 302 to move to one side, and another material box 310 is moved above the conveyor belt assembly 302 to facilitate the replacement of the used material box 310. Then, another material box 310 full of workpieces is installed above the movable frame 305. When the material box 310 above the conveyor belt assembly 302 is used up, the incomplete gear 306 drives the movable frame 305 to move in the opposite direction, and so on and so forth, which is convenient for continuous loading; The function of the material transfer structure 4 is to move the conveyed material to the punching position. The vertical lifting assembly 401 can drive the horizontal moving rail 402 to perform vertical lifting and lowering movements to adjust the height to meet different work requirements. The material transfer motor is started, and its output shaft drives the active half gear 408 to rotate. The two active half gears 408 alternately engage with the driven gear 407, thereby driving the driven gear 407 to rotate alternately in forward and reverse directions. The driven gear 407 is connected to the material transfer screw 403, so that the material transfer screw 403 also rotates alternately in forward and reverse directions, driving the two clamping manipulators 406 to move to one side at the same time. When one of the clamping manipulators 406 moves to the edge of the operating table 2 to clamp the workpiece on the conveyor belt assembly 302, the other clamping manipulator 406 moves to the middle of the operating table 2 and places the workpiece above the punching hole. The two clamping manipulators 406 alternately place the workpiece.

[0034] The positioning structure 5 is used to accurately position the material placed on the operating table 2. The positioning drive motor 503 is activated, driving the positioning screw 502 to rotate. Because the positioning blocks 504 contact the threads on the positioning screw 502 in opposite directions and the positioning blocks 504 slide within the movable groove 501, the two positioning blocks 504 will move toward the center simultaneously. When the outer walls of the positioning blocks 504 abut the outer walls of the workpiece, the workpiece is positioned, ensuring that the workpiece is accurately positioned during the stamping process, thereby ensuring stamping quality.

[0035] Under the unified coordination of the control system, the feeding structure 3 continuously transports the material to the operating table 2, the material moving structure 4 moves the material to the stamping position in a timely manner, and the positioning structure 5 accurately positions the material. This patent uses a visual system to facilitate the precise transportation, transfer and positioning of materials.
