[0032] Combination Figures 1 to 7 As shown, a punching machine feeding tool provided by the utility model includes a conveyor 1, a positioner 2 and a tool control center 3.

[0033] Combination Figures 1 to 7 As shown, the conveyor 1 passes through the punching machine, the fixed end of the punching machine is buried in the conveyor 1, and the upper surface of the fixed end of the punching machine coincides with the upper surface of the conveyor 1, and the moving end of the punching machine is located directly above the conveyor 1; the positioner 2 includes a laser ranging sensor 21 and a transverse track 22, the laser ranging sensor 21 is located in the conveyor 1 above the rear half of the punching machine, and the measuring head of the laser ranging sensor 21 faces the conveyor 1, the laser ranging sensor 21 is slidably assembled on the transverse track 22, and the transverse track 22 is fixedly connected to the conveyor 1; the tooling control center 3 is electrically connected to the conveyor 1 and the laser ranging sensor 21, and the tooling control center 3 controls the conveyor 1 to stop moving when receiving the measurement value of the laser ranging sensor 21 that suddenly changes from large to small.

[0034] In this embodiment, the laser ranging sensor 21 is used to observe the position information of the plate below the laser ranging sensor 21, and the lateral position of the laser ranging sensor 21 is adjusted by the lateral track 22, so that the minimum margin position of the punching hole on the plate passes under the laser ranging sensor 21. When the front end of the plate passes or a punching hole on the plate passes, the laser ranging sensor 21 will release a signal to the tooling control center 3, and the tooling control center 3 controls the conveyor 1 to stop. At this time, the stamping process is carried out, and the distance between the laser ranging sensor 21 and the punching machine is fixed, and the distance between the laser ranging sensor 21 and the punching machine is the margin of the two punching holes.

[0035] In this embodiment, the positioning is based on the front end of the plate or the end of a punching hole on the plate, and only the position and size of the minimum margin need to be considered. By fixing the distance between the laser ranging sensor 21 and the punching machine, it is ensured that the margins of each punching hole are equal during the punching process. By adjusting the lateral position of the laser ranging sensor 21, the minimum margin position of the punching hole on the plate passes under the laser ranging sensor 21, so that the distance between the laser ranging sensor 21 and the punching machine is the minimum margin of the two punching holes.

[0036] In this embodiment, combined with Figure 6 , Figure 7 As shown, by adjusting the lateral position of the laser ranging sensor 21, the punching machine feeding fixture can adapt to a variety of punching shapes. The horizontal dotted line in the figure indicates the position on the plate passing directly below the laser ranging sensor 21, and the vertical dotted line indicates the position of the plate directly below the laser ranging sensor 21 when the laser ranging sensor 21 sends a signal.

[0037] In some embodiments, in combination Figures 1 to 3 As shown, the positioner 2 also includes a longitudinal track 23, and the longitudinal track 23 is slidably assembled on the transverse track 22. The laser ranging sensor 21 is slidably assembled on the longitudinal track 23. The establishment of the longitudinal track 23 makes the position of the laser ranging sensor 21 more flexible. By adjusting the position of the laser ranging sensor 21 on the longitudinal track 23 and changing the distance between the laser ranging sensor 21 and the punching machine, more refined control of the margin can be achieved. For example, when the position of the minimum margin is at the edge, the laser ranging sensor 21 cannot be adjusted to above the minimum margin. At this time, the laser ranging sensor 21 is moved to above the margin that differs from the minimum margin by an integer, and the position of the laser ranging sensor 21 on the longitudinal track 23 is adjusted to increase or decrease the distance between the optical ranging sensor 21 and the punching machine by the size of the integer to ensure the size of the minimum margin.

[0038] In some embodiments, in combination Figures 1 to 4As shown, it also includes a drive motor 4, and rack features are provided on the transverse track 22 and the longitudinal track 23. The drive motor 4 is electrically connected to the tooling control center 3, and the number of drive motors 4 is 2. The two drive motors 4 are respectively fixedly connected to the laser ranging sensor 21 and the longitudinal track 23, and the driving end of the drive motor 4 is meshed with the corresponding rack features. The laser ranging sensor 21 is driven by the drive motor 4 electrically connected to the tooling control center 3 to control the position of the laser ranging sensor 21 on the transverse track 22 and the longitudinal track 23, so that after the size information of the stamping product is input into the tooling control center 3, the laser ranging sensor 21 automatically moves to the specified position, replacing the work process that should have been performed manually by the operator, with higher positioning accuracy and a deeper degree of automation.

[0039] In some embodiments, in combination Figure 1 to Figure 2 As shown, the tooling control center 3 is electrically connected to the punching machine. The tooling control center 3 starts the conveyor 1 after receiving the signal after the punching machine has completed punching, forming a logical closed loop in operation, eliminating the step of setting the stop time of the conveyor 1. At the same time, when a problem occurs in a certain link, the machine will stop, avoiding the continued operation of part of the structure causing material waste or equipment damage.

[0040] In some embodiments, in combination Figure 1 to Figure 2 As shown, the conveyor 1 includes a conveyor belt 11, the number of the conveyor belts 11 is 2, and the two conveyor belts 11 are distributed in parallel. The fixed end of the punching machine is located between the two conveyor belts 11, and the plate is driven by the two conveyor belts 11 to ensure the reliability of the plate driving in the whole process, and at the same time will not conflict with the position of the punching machine.

[0041] In some embodiments, in combination Figure 1 , Figure 2 and Figure 5 As shown, the conveyor 1 also includes a vacuum suction cup 12, and the vacuum suction cup 12 is evenly distributed on the outer surface of the conveyor belt 11. The vacuum suction cup 12 adsorbs the plate to ensure that the plate does not slide when the conveyor 1 stops or starts, thereby improving the control of the plate position accuracy. At the same time, the vacuum suction cup 12 is embedded in the conveyor belt 11, which can prevent the vacuum suction cup 12 from lifting the plate, thereby ensuring that the plate is not in full contact with the upper surface of the conveyor belt 11.

[0042] In some embodiments, in combination Figure 1 , Figure 2 As shown, the conveyor 1 also includes a limiting protrusion 13, which is integrally formed on the outermost side of the upper surface of the conveyor 1 and plays a limiting role in the process of the plate entering the conveyor 1, thereby reducing the requirements for the entry position and angle of the plate in the process of the plate entering the conveyor 1.

[0043] In some embodiments, in combination Figure 1 , Figure 2 As shown, the conveyor 1 also includes a transmission roller 14, which is located between the two conveyor belts 11. The transmission roller 14 is only provided in front of the punching machine. The transmission rollers 14 are closely arranged, and the highest point of the transmission roller 14 coincides with the surface of the conveyor belt 11. The transmission roller 14 can provide support for the middle part of the plate to prevent the middle part of the plate from being deformed due to its own weight and affecting the stamping effect. At the same time, the friction between the transmission roller 14 and the surface of the plate is smaller, which is beneficial to improving the stamping quality.

[0044] In some embodiments, in combination Figure 1 , Figure 2 As shown, it also includes a smoothing wheel 5, which is located directly above the frontmost conveying roller 14, and the gap between the smoothing wheel 5 and the conveying roller 14 is the same as the thickness of the plate. The plate is smoothed by the cooperation of the smoothing wheel 5 and the frontmost conveying roller 14, thereby improving the flatness of the plate entering the conveyor 1.

[0045] In some embodiments, in combination Figure 1 , Figure 2 As shown, it also includes a brush wheel 6, on which brush strips are evenly distributed. The brush wheel 6 is located in front of the entrance of the conveyor 1. The number of the brush wheels 6 is 2, and the two brush wheels 6 are respectively attached to the upper and lower surfaces of the plate. The impurities on both sides of the plate are brushed away by the brush wheels 6, which is beneficial to improving the stamping quality. At the same time, the brush wheels 6 arranged opposite to each other up and down ensure the balance of force on the plate, reducing the impact on the plate during the process of brushing away impurities.

[0046] Working process: Pre-adjust the position of the laser distance sensor 21 on the transverse track 22 according to the contour of the punching so that the position of the minimum margin is achieved, so that the laser distance sensor 21 passes directly below the laser distance sensor 21, and the position of the laser distance sensor 21 on the longitudinal track 23 is adjusted according to the size of the minimum margin, and the distance between the laser distance sensor 21 and the punching machine is changed to achieve the control of the size of the margin; then put the plate in, the plate first passes through the brush wheel 6 to brush off the surface impurities and then enters the conveyor 1; the plate first passes through the flattening wheel 5 and the frontmost conveying roller 14 to improve the flatness of the plate; then the two sides of the plate are attached to the conveyor belt 11, and the vacuum suction cup 1 embedded in the conveyor belt 11 2 The sheet is adsorbed on the conveyor belt 11 to prevent the sheet from sliding, and the middle part of the sheet is supported by the conveyor roller 14 to prevent friction between the sheet and the conveyor 1; when the front end of the sheet or the end of the punched hole on the sheet passes under the laser distance sensor 21, the laser distance sensor 21 sends a signal to the tooling control center 3, and the tooling control center 3 controls the conveyor 1 to stop and start the punching machine; after the punching machine completes the punching, it sends a signal to the tooling control center 3, and the tooling control center 3 starts the conveyor 1 again; until the front end of the next sheet or the end of the punched hole on the sheet passes under the laser distance sensor 21, and the above process is repeated.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
