The punching groove 231 and the positioning groove 241 are arranged in a through manner. When the punching knife 34 punches the product in the positioning groove 241, the punching waste falls below the fixing plate 21 from the punching groove 231.
[0043] Please refer to Figure 1 and Figure 2 Below the first clearance groove 271 of the fixing plate 21 of the transfer mechanism 20, there is a waste box 50 for collecting punching waste. A hopper 28 for guiding the punching waste is arranged below the first clearance groove 271 of the fixing plate 21 of the transfer mechanism 20, and a waste opening 281 corresponding to the waste box 50 is opened below the hopper 28.
[0044] Please apply medicine Figure 3 、 Figure 4 and Figure 9 On the upper surface of the first mounting plate 33 of the punching mechanism 30, at least two guiding columns 35 are arranged at intervals. The first fixing frame 31 is provided with guiding holes for accommodating the guiding columns 35 to be movably arranged. By arranging the guiding columns 35, it can be ensured that the first mounting plate 33 moves straight up and down during the ascending or descending process, thereby avoiding the situation that the first mounting plate 33 rotates around the first telescopic end of the first cylinder 32, resulting in punching deviation and scrapping of the product.
[0045] Please refer to Figures 1 - 10, the punching mechanism 30 includes two of the first cylinders 32. A first mounting plate 33 is installed on the first telescopic end of each of the first cylinders 32, and several punching knives 34 are installed under each of the first mounting plates 33. Two positioning seats 24 are installed on the sliding plate 23, and each positioning seat 24 is arranged corresponding to each of the first mounting plates 33. On the lower surface of the second mounting plate 43 of the blanking mechanism 40, two groups of suction cup grippers 44 are provided, and each group of suction cup grippers 44 is arranged corresponding to each of the positioning seats 24. In this embodiment, the punching-related units in the transfer mechanism 20, the punching mechanism 30, and the blanking mechanism 40 are arranged in pairs, which can achieve simultaneous transfer, simultaneous punching, and simultaneous blanking, so that the present utility model can achieve double efficiency. Further, in other embodiments, more groups can also be provided, which are not particularly limited herein.
[0046] In this embodiment, the driving device 25, the first cylinder 32, and the second cylinder 42 are controlled by a control unit, and the first cylinder 32, the second cylinder 42, and the suction cup grippers 44 are connected to an external air source device through air pipes.
[0047] Please refer to Figure 1 and Figure 2 , the workbench 10 includes a support frame 11 and a shielding plate 12 connected to the support frame 11. The transfer mechanism 20 is clamped on the support frame 11, and the shielding plates 12 are provided on both opposite sides of the transfer mechanism 20, the punching mechanism 30, and the blanking mechanism 40 along the parallel line of the slide rail 22. More specifically, in the horizontal direction, the fixed plate 21 of the part where the blanking mechanism 40 is installed protrudes from the workbench 10, so that the suction cup grippers 44 of the blanking mechanism 40 can unload the grabbed products onto a receiving tray or a production line for the next process.
[0048] Further, the control unit is arranged in the space enclosed by the shielding plate 12 located below the fixed plate 21, and an opening 13 for the waste box 50 to enter and exit is provided on one of the shielding plates 12 located below the fixed plate 21. The waste box 50 is placed into the workbench 10 through the opening 13 to collect punching waste, or the waste box 50 filled with punching waste is taken out through the opening 13, and the punching waste in the waste box 50 is collected and processed.
[0049] When the automatic punching equipment of the present utility model is in use,
[0050] First, the driving wheel 251 of the driving device 25 rotates clockwise, and the sliding plate 23 moves along the slide rail 22 from the second end to the first end until the driving device 25 stops working when the sensor 60 senses the sliding plate 23. The external manipulator grabs the product and places it in the positioning groove 241 of the positioning seat 24 located above the sliding plate 23;
[0051] Next, the driving wheel 251 of the driving device 25 rotates counterclockwise, and the sliding plate 23 moves along the slide rail 22 from the first end to the second end. When the positioning seat 24 is positioned below the punching mechanism 30, the first cylinder 32 starts to work, driving the punching knife 34 to punch downward for the product in the positioning groove 241. The punching waste falls into the hopper 28 through the punching groove 231 and the first clearance groove 271, and then falls into the waste box 50 through the waste outlet 281 of the hopper 28;
[0052] Then, the driving wheel 251 of the driving device 25 continues to rotate counterclockwise, and the sliding plate 23 continues to move along the slide rail 22 towards the second end. When the positioning seat 24 is positioned below the blanking mechanism 40 and is positioned, the second cylinder 42 starts to work, driving the suction cup gripper 44 to move downward and grab the product. When the suction cup gripper 44 grabs the product and then drives the product to move upward to the highest position, the driving wheel 251 of the driving device 25 rotates clockwise, driving the sliding plate 23 to move from the second end towards the first end direction. At the same time, the suction cup gripper 44 discharges the product through the second clearance groove 272;
[0053] The above actions are repeated to perform automatic punching on the product.
[0054] The automatic punching device of the present utility model realizes full-automatic punching of the product by sliding the sliding plate 23 carrying the product along the slide rail 22, performing a punching action at the position of the punching mechanism 30, and discharging the punched product at the position of the blanking mechanism 40, greatly improving the working efficiency.
[0055] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
