[0002] Die-cutting machines are mainly used for die-cutting various shapes of single- and double-sided self-adhesive labels, protective films, gaskets, dustproof nets, and copper and aluminum foil products. They are widely used in post-printing die-cutting of front and back covers, windows, monitors, microphones, earpieces, keyboards, batteries, and labels in electronic products such as mobile phones, laptops, PDAs, digital cameras, and audio equipment.

Detailed Implementation
[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0029] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0030] Example
[0031] To address the issue that existing die-cutting equipment often fails to detect seams after stacking multiple materials, leading to functional and usability issues in products, this paper refers to... Figures 1-4 As shown, this application discloses a die-cutting device with material joint detection marks, including a plurality of die-cutting machines and a plurality of detection marking mechanisms 20. The plurality of detection marking mechanisms 20 are disposed on the outside of some of the die-cutting machines. The detection marking mechanism 20 includes a detection component and a marking component.
[0032] The detection component includes a Z-shaped bracket 21 rotatably mounted on the die-cutting machine base and a color mark probe 22 mounted on the Z-shaped bracket 21. The Z-shaped bracket 21 is provided with a mounting base 221, and the color mark probe 22 is fixed on the mounting base 221.
[0033] The marking assembly includes a lifting and rotating drive module 23 mounted on a Z-shaped bracket 21 and a marking pen 24 connected below the lifting and rotating drive module.
[0034] Before several die-cutting machines start working, the operator rotates the Z-shaped bracket 21 so that the color mark probe 22 and the lifting and rotating drive assembly are positioned above the discharge end of the corresponding die-cutting machine. In practice, several color mark probes 22 will simultaneously detect the moving material. If one color mark probe 22 detects that the color of the material is unqualified (the entire equipment will stop), the lifting and rotating drive module 23 will drive the marking pen 24 to descend and rotate to mark the abnormal position. After that, the operator will process the marked joint.
[0035] In order to control the entire equipment and quickly issue abnormal notifications (this part is not shown in this application), this application also includes a controller and an alarm. The color mark probe 22, the lifting and rotating drive module 23 and the alarm are all electrically connected to the controller. In specific implementation, if the color mark probe 22 detects a joint, it will control all die-cutting machines to stop working through the controller and the alarm will issue an alarm signal. At this time, the lifting and rotating drive module 23 will drive the marker pen 24 to descend, thereby marking the abnormal position.
[0036] For example, the lifting and rotating drive module 23 of this application includes a first cylinder 231 that passes through the Z-shaped bracket 21 and extends to the upper and lower sides, a first plate 232 disposed inside the cylinder, a lead screw 233 that is rotatably disposed inside the first plate 232 and extends downward, a second cylinder 234 that is inserted inside the first cylinder 231 and fixed to the lead screw nut 2331, a first umbrella-shaped tooth 235 that is connected to the lead screw 233 above the first plate 232, a first rotating shaft 236 that is connected to the first cylinder 231 above the first plate 232, a first bevel tooth 237 that is mounted on the first rotating shaft 236 and meshes with the first umbrella-shaped tooth 235, and a first bevel tooth 237 that is disposed above the Z-shaped bracket 21 on the first cylinder 231 and connected to the first rotating shaft 236. The system includes a geared motor 238, a second plate 3411 located inside and below the second cylinder 234, a second rotating shaft 2342 rotatably located inside the second plate 3411 and extending to the upper and lower sides, a disc 2347 connected to the second rotating shaft 2342 at the bottom of the second profiled cylinder, a second umbrella-shaped tooth 2343 connected to the first rotating shaft 236 above the second plate 3411, a third rotating shaft 2344 connected to the second cylinder 234 above the second plate 3411, a second bevel tooth 2345 mounted on the third rotating shaft 2344 and meshing with the second umbrella-shaped tooth 2343, and a second geared motor 2346 connected to the third rotating shaft 2344 outside and below the second cylinder 234; a marker pen 24 is located below the edge of the disc 2347.
[0037] When the color mark probe 22 detects an abnormality, the first reduction motor 238 drives the first rotating shaft 236 to rotate, causing the first bevel gear 237 to drive the first umbrella gear 235 to rotate. At this time, the lead screw 233 will drive the second cylinder 234 to descend and extend. When the marking pen 24 contacts the material joint, the second reduction motor 2346 drives the third rotating shaft 2344 to rotate, causing the second bevel gear 2345 to drive the second umbrella gear 2343 to rotate. At this time, the second rotating shaft 2342 will drive the disc 2347 to rotate. In this way, the marking pen 24 located below the disc 2347 will draw a mark at the material joint.
[0038] In one specific embodiment, the die-cutting machine base of this application is provided with a rotation damper 211, and the bottom of the Z-shaped bracket 21 is provided with a fourth rotating shaft 213 inserted inside the rotation damper 211. In this way, the operator can drive the Z-shaped bracket 21 to rotate so that the color mark probe 22 and the lifting and rotating drive module 23 are located above the corresponding die-cutting machine output end. In actual use, the Z-shaped bracket 21 will not easily deflect, and the effect of use is better.
[0039] In one specific embodiment, an annular step 23411 is integrally formed on the lower inner side of the second cylinder 234, and an annular guide rail 234111 is provided below the annular step 234111. The disc 2347 is slidably connected to the annular guide rail 234111.
[0040] In a preferred embodiment, to prevent the pen tip from being damaged during rapid descent of the marking pen 24, a pen holder 25 is provided below the edge of the disc 2347. A bottom sleeve 26 is screwed to the bottom of the pen holder 25 via a threaded structure. A clearance groove 261 is provided in the middle of the bottom sleeve 26. The bottom sleeve 26 has several overlapping grooves 262 arranged in a ring around the center of the clearance groove 261. Several protrusions 241 are integrally provided below the marking pen 24. When the marking pen 24 is placed inside the pen holder 25, the several protrusions 241 of the marking pen 24 overlap in the several overlapping grooves 262 and allow the pen tip to pass through the clearance groove 261. A compression spring 27 is provided above the marking pen 24 and abuts against the pen holder 25. When the marking pen 24 descends and contacts the material and when the marking pen 24 is making a mark, the compression spring 27 can play an elastic support role. In this way, the marking pen 24 will not be easily damaged during rigid operation and has high practical value.
