[0021] Refer to Figures 1-6 , the detection module 3 further includes an electric drive rod 301, and the electric drive rod 301 is fixedly connected to the outer side of one side of the protection observation frame 4. A plurality of smooth openings are equidistantly arranged on one side of the protection observation frame 4. A guide cylinder 302 is slidably connected inside each of the plurality of smooth openings. One end of each of the plurality of guide cylinders 302 facing the conveyor belt 2 is fixedly connected to the same lifting mounting plate 303. The driving end of the electric drive rod 301 passes through the protection observation frame 4 and is fixedly connected to one side of the lifting mounting plate 303.

[0022] Refer to Figures 1-6 , a detection platform 304 is fixedly connected to one side of the lifting mounting plate 303. A plurality of mounting grooves 305 are equidistantly arranged on one side of the detection platform 304. Two adjusting tooling blocks 306 are connected to the inside of each of the plurality of mounting grooves 305 by bolts. An installation opening is arranged on one side of each of the plurality of adjusting tooling blocks 306. A limit scale frame 308 is fixedly connected to the inside of each of the plurality of installation openings. A through hole is arranged on one side of each of the plurality of limit scale frames 308. The detection scale plate 312 slides inside the through hole.

[0023] Refer to Figures 1-6 , mounting openings are arranged on both sides of each of the plurality of limit scale frames 308, and the same limit round rod 310 is fixedly connected to the opposite side of the two mounting openings. The self-adjusting lifting block 309 slides outside the limit round rod 310. Two reset springs 311 are fixedly connected to both sides of the self-adjusting lifting block 309.

[0025] In a specific application scenario, the sewing machine plate body 7 is transported through the conveyor belt 2. When it is transported below the detection platform 304, the conveyor belt 2 stops transporting at this time. Then, the first electric drive rod 301 is started, and the first electric drive rod 301 drives the detection platform 304 below the lifting mounting plate 303 to move downward. At this time, the value of the detection scale plate 312 on the detection platform 304 is consistent with the value of the depth of the drilling to be processed. The detection platform 304 continues to descend, making the detection reaction column 318 contact the bottom of the drilling of the sewing machine plate body 7. When the drilling depth is relatively shallow, at this time, the detection reaction column 318 abuts against the bottom of the drilling and moves upward. At this time, the detection reaction column 318 drives the detection scale plate 312 to move upward inside the limit scale frame 308. The rising height is photographed by the visual monitor 307. The value obtained by subtracting the value to be processed from the photographed value is the depth of this drilling. At the same time, for deeper drillings that do not abut against the detection reaction column 318, at this time, the electric telescopic rod 315 is started, and the electric telescopic rod 315 drives the detection scale plate 312 to move downward inside the limit scale frame 308. When the detection reaction column 318 below the detection scale plate 312 abuts against the inside of the drilling, at this time, the value of the detection scale plate 312 moving downward is photographed by the visual monitor 307. The value obtained by adding the photographed value to the value to be processed is the depth of this drilling. The values are collected and processed by the data receiving and display 5. Through the detection module 3, it is avoided that the staff detect each drilling one by one, thereby improving the reliability of the detection data of the drilling depth, reducing the labor force of workers while improving the detection efficiency.

[0026] Refer to Figure 1 , Figure 7 and Figure 8 , a detection and positioning module 6 is arranged inside the protective observation frame 4, and the detection and positioning module 6 includes a second electric drive rod 603. Circular holes one are opened on both sides of the protective observation frame 4. Inside multiple circular holes one, guide round rods 601 are slidably connected. At one end of two guide round rods 601 on the same side, a horizontal moving plate 602 is fixedly connected. The driving end of the second electric drive rod 603 is fixedly connected to one side of the horizontal moving plate 602.

[0027] Reference Figure 1 、 Figure 7 and Figure 8 As shown in FIGS. Figure 7 and Figure 8 , on the opposite sides of the two horizontal moving plates 602, there are fixedly connected mounting round tubes 604. On one side of each of the two mounting round tubes 604, there are second round holes. Inside each of the two second round holes, there is a sliding connection with a resisting column 606. On one side of each resisting column 606, there is fixedly connected a first telescopic spring 605, and one side of the first telescopic spring 605 is fixedly connected to the inner side of the mounting round tube 604.

[0028] Reference Figure 7 and Figure 8 As shown in FIGS. Figure 7 and Figure 8 , on one side of each of the two resisting columns 606, there is fixedly connected a tooling cross bar 607. On one side of each of the two tooling cross bars 607, there is a movable connection with two opening and closing resisting rods 608. On one side of each of the multiple opening and closing resisting rods 608, there is a movable connection with a tooling rotating block 609. On the opposite sides of the two tooling rotating blocks 609 on the same side, there is fixedly connected the same second telescopic spring 610.

[0029] Reference Figure 7 and Figure 8 As shown in FIGS. Figure 7 and Figure 8 , on one side of each of the two opening and closing resisting rods 608 on the same side, there is a movable connection with the same tooling limiting frame 611. On both sides of each of the multiple tooling limiting frames 611, there is an equidistant movable connection with limiting rollers 612. On one side of each of the multiple tooling limiting frames 611, there is fixedly connected a resisting plate 613.

[0030] In a specific application scenario, during the transmission of the sewing machine plate body 7, at this time, the electric drive rod two 603 drives the horizontal moving plate 602 to move along the guiding round rod 601. The first telescopic spring 605 and the slidable resisting column 606 provide a flexible contact pressure to the sewing machine plate body 7. The tooling cross bar 607, the opening and closing resisting rod 608, and the tooling rotating block 609 cooperate with the second telescopic spring 610 to realize the dynamic conveying of the sewing machine plate body 7, ensuring the stable positioning and smooth movement of the sewing machine plate body 7 during the detection process, and realizing the accurate detection of the punching depth of the sewing machine plate body 7.

[0031] A method for using a punching depth detection device for sewing machine plate processing, using a punching depth detection device for sewing machine plate processing as described above, includes the following steps: Step 1: The sewing machine plate body 7 is transmitted through the conveyor belt 2. When it reaches below the detection platform 304, at this time, the conveyor belt 2 stops conveying, and then the electric drive rod one 301 is started. The electric drive rod one 301 drives the detection platform 304 below the lifting mounting plate 303 to move downward; Step 2: At this time, the value on the detection scale plate 312 on the detection platform 304 is consistent with the value of the drilling depth to be processed. The detection platform 304 continues to descend so that the detection reaction column 318 contacts the bottom of the drill hole in the sewing machine plate body 7. When the drilling depth is relatively shallow, at this time, the detection reaction column 318 abuts against the bottom of the drill hole and moves upward. At this time, the detection reaction column 318 drives the detection scale plate 312 to move upward inside the limit scale frame 308. The rising height is photographed by the visual monitor 307. The value obtained by subtracting the value to be processed from the photographed value is the depth of the drill hole. Step 3: At the same time, for the relatively deep drill hole that does not abut against the detection reaction column 318, the electric telescopic rod 315 is started at this time. The electric telescopic rod 315 drives the detection scale plate 312 to move downward inside the limit scale frame 308. When the detection reaction column 318 below the detection scale plate 312 abuts against the inside of the drill hole, at this time, the value of the detection scale plate 312 that moves downward is photographed by the visual monitor 307. The value obtained by adding the photographed value to the value to be processed is the depth of the drill hole. The value is collected and processed by the data receiving and display 5.
