Referring to fig. 1, a die-cutting apparatus 100 is used for die-cutting a material 200. The die-cutting apparatus 100 includes a carrier 10, a sensor head 20, a die-cutting mechanism 30, and a circuit sensor (not shown). The carrier 10 has a first potential and the top is used for carrying a plurality of parallel materials 200. The sensing head 20 has a second electrical potential and is arranged spaced apart from the carrier stage 10 without contact. Sensing head 20 is used to contact the end of stock material 200. The loop sensor is electrically connected to the carrier 10 and the sensing head 20, respectively, for sensing current. The punching mechanism 30 is used for punching the material 200 on the carrier table 10. The first potential and the second potential have a potential difference, when the end of the material 200 contacts the sensing head 20, the potential difference can enable the material 200 to generate current, so that the bearing table 10, the sensing head 20 and the material 200 form an electric loop, and after the loop sensor senses the current, the punching mechanism 30 punches the material 200 to ensure that the punched material 200 is in place in length. In one embodiment, the material 200 is a metal thin strip, which is conductive, and the material 200 is automatically fed after each punching, if the feeding length is in place, the end of the material 200 will contact the probe 20, and the material 200 is placed on the carrier 10, so that the carrier 10, the probe 20, and the material 200 form an electrical circuit, and the punching mechanism 30 performs punching; if the feed length is short, the end of the material 200 cannot contact the sensing head 20, the susceptor 10, the sensing head 20, and the material 200 cannot form an electrical circuit, and the punching mechanism 30 does not perform punching, thereby preventing a punching failure.

In one embodiment, the first potential of the carrier 10 is zero potential, and the second potential of the sensing head 20 is high potential above the first potential, for example, to increase the safety factor, the second potential of the sensing head 20 is 12V, and the potential difference between the first potential and the second potential creates a weak point in the material 200. In another embodiment, the die-cutting apparatus 100 further includes an alarm (not shown) electrically connected to the carrier 10 and the sensing head 20, when the length of the material 200 is not in place after feeding, the material 200 cannot contact the sensing head 20, and thus the carrier 10, the sensing head 20, and the material 200 cannot form an electrical circuit, and the alarm gives an alarm to prevent poor die-cutting caused by insufficient feeding.

Referring to fig. 2, the carrier 10 has a position-avoiding groove 11, and the position-avoiding groove 11 penetrates through a side of the carrier 10 away from the material 200 for accommodating the sensing head 20. The sensing head 20 is provided with a contact surface 21, the contact surface 21 being for contacting and stopping an end of the material 200. The contact surface 21 is perpendicular to and intersects the plane of the top surface of the carrier 10, thereby ensuring that the contact surface 21 is completely contacted after the material 200 is fed into position.

The top surface of the bearing table 10 is provided with a plurality of protrusions 12, and a positioning groove 13 is formed between two adjacent protrusions 12. The positioning groove 13 is used for accommodating the material 200, and the side wall of the protruding part 12 is used for limiting the left and right movement of the material 200, so that the material 200 is prevented from shaking. The length direction of the positioning groove 13 is perpendicular to the contact surface 21 to guide the material 200 to move toward the contact surface 21. In one embodiment, six positioning slots 13 are formed on the carrier 10 to simultaneously accommodate six materials 200, and one sensing head 20 is disposed at an end of each material 200.

Referring to fig. 3, the die-cutting apparatus 100 further includes an adjustment mechanism 40. The adjusting mechanism 40 includes a first driver 41, a first slide rail 42, and a first slider 43. The sensing head 20 is disposed on the first slider 43, the first slider 43 is slidably connected to the first slide rail 42 and disposed parallel to the length direction of the material 200, and the driving end of the first driver 41 is connected to the first slider 43 for driving the first slider 43 to drive the sensing head 20 to move along the first slide rail 42, so as to adjust the punching length of the material 200, or drive the sensing head 20 to be away from the carrier 10 and the material 200, so as to take out the punched material 200. By way of illustrative example, the first actuator 41 is a pneumatic cylinder.

The die-cutting apparatus 100 further comprises a feeding mechanism 50, and the feeding mechanism 50 comprises a second driver 51, a lower clamp block 52, an upper clamp block, and a third driver (not shown). The lower clamping block 52 and the third driver are arranged at the driving end of the second driver 51, the upper clamping block is arranged at the driving end of the third driver, the top surface of the lower clamping block 52 is used for bearing the material 200, and the height of the lower clamping block is the same as that of the top surface of the bearing table 10, the third driver is used for driving the upper clamping block to descend until the upper clamping block and the lower clamping block 52 clamp the material 200, and after clamping, the second driver 51 is used for driving the material 200 to move towards the sensing head 20 until the end part of the material 200 contacts the material 200. For example, the second actuator 51 and the third actuator are air cylinders, and in other embodiments, the lower clamping block 52 and the upper clamping block may be driven by an air cylinder to clamp or release the material 200.

In order to facilitate taking out the punched material 200, the punching device 100 further includes a discharging mechanism 60, and the discharging mechanism 60 includes a sliding plate 61, a second sliding rail 62 and a fourth driver 63. The second slide rail 62 is arranged along a direction perpendicular to the feeding direction of the material 200, the slide plate 61 is slidably arranged on the second slide rail 62, the carrier table 10 is arranged on the slide plate 61, and the fourth driver 63 is used for driving the slide plate 61 to move between the punching position and the discharging position so as to take out the punched material 200. It should be noted that the first driver 41 needs to move the measuring head 20 away from the carrier 10 before the fourth driver 63 drives the slide 61 to the discharge position, so as to prevent the measuring head 20 from interfering with the movement of the carrier 10.

The discharging mechanism 60 further includes a stop member 64, and the stop member 64 is disposed at an end of the second slide rail 62 facing away from the fourth driver 63. The stopper 64 serves to stop the movement of the slide plate 61. The side of the stopper 64 facing the slide plate 61 is provided with a contact sensor (not shown) for controlling the fourth driver 63 to stop after contacting the slide plate 61.

Referring to fig. 1, the punching mechanism 30 includes a punch 31, a table 32, a guide 33, a moving table 34, and a punching plate 35. The guide 33 is vertically disposed. The platform 32 is placed on top of the guide 33. The punch 31 is provided on the table 32. The moving table 34 is slidably coupled to the guide 33. The die-cutting plate 35 is provided below the moving table 34. The driving end of the punch 31 is connected to the top of the moving table 34 for driving the punching plate 35 to punch the material 200 on the carrier table 10. The guide 33 is used for guiding the moving stage 34. In one embodiment, four guiding elements 33 are disposed around the carrier 10.

In summary, one embodiment of the die-cutting device 100 for die-cutting the material 200 is as follows: the feeding mechanism 50 drives the material 200 to feed, when the end of the material 200 contacts the sensing head 20, the bearing table 10, the sensing head 20 and the material 200 form an electric loop, and the punching mechanism 30 punches after the loop sensor senses the current; after punching, the first driver 41 drives the sensing head 20 to move away from the bearing table 10, and the fourth driver 63 drives the sliding plate 61 to the discharging position so as to take materials; after the material is taken, the fourth driver 63 drives the sliding plate 61 to return to the stamping position, and the feeding mechanism 50 drives the material 200 to feed again; if the length of the material 200 is not in place and cannot contact the sensing head 20 after feeding, the alarm gives an alarm for reminding. The above process is repeated to die cut the stock material 200 multiple times.

After the punching device 100 contacts the sensing head 20 through the material 200, the potential difference between the sensing head 20 and the bearing table 10 causes the material 200 to generate current, and after the loop sensor senses the current, the punching mechanism 30 punches the material 200, so as to achieve the purpose of ensuring that the punched material 200 is in place in length.
