Description

Technical Field

[0001] This invention relates to the field of cultural and creative packaging processing equipment technology, specifically to a photoelectric positioning punching machine for cultural and creative packaging boxes. Background Technology

[0002] As an important carrier of cultural and creative products, cultural and creative packaging boxes are made of diverse materials, such as paper, wood, plastic, and leather. Their surfaces are usually printed with complex patterns, textures, or processes such as hot stamping and embossing to enhance the product's aesthetics and cultural connotation. In the processing of cultural and creative packaging boxes, punching is a key step, used to enable the packaging box to be folded and shaped, secured with ropes, and have labels pasted on. The precision requirements for the punching position are extremely high.

[0003] Most photoelectric positioning punching machines used in the processing of cultural and creative packaging boxes in the current technology adopt a single photoelectric sensor for positioning. The working principle is to use the photoelectric sensor to emit photoelectric signals and receive the signals reflected by the surface of the packaging box to determine the positioning reference. However, due to the printing patterns and textures on the surface of the cultural and creative packaging box, the photoelectric signal will be affected by reflection and scattering interference. Different materials have large differences in reflectivity, which makes it difficult for the photoelectric sensor to accurately identify the positioning reference point. This easily leads to positioning and identification errors, resulting in problems such as punching offset and hole misalignment. This seriously affects the processing quality and aesthetics of the cultural and creative packaging box, and may even cause the product to be scrapped.

[0004] Combining the above issues, we find that existing photoelectric positioning punching machines for cultural and creative packaging boxes have difficulty simultaneously avoiding the problems mentioned above. Even if they can solve these problems, they require the use of external tools, thus failing to achieve the desired effect. Therefore, we propose a photoelectric positioning punching machine for cultural and creative packaging boxes. Summary of the Invention

This allows for the identification of indentations at the punched location, further assisting the photoelectric positioning component in pinpointing the punched position. This physical positioning method further avoids reflection and scattering interference from printed patterns on the packaging box surface. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-6This invention provides a technical solution: a photoelectric positioning punching machine for cultural and creative packaging boxes, including a base 1, a punching mechanism 2 above the base 1, the punching mechanism 2 including a mounting frame 201, the bottom end of the mounting frame 201 being fixedly connected to the upper surface of the base 1, a connecting plate 202 being fixedly installed on the outer surface of the base 1, a controller 203 being fixedly installed on the upper surface of the connecting plate 202, the controller 203 inputting the punching pattern and data of the packaging box, a laser generator 204 being fixedly installed on the outer surface of the mounting frame 201, a robotic arm 205 being provided inside the mounting frame 201, a laser cutting head 206 being fixedly installed on the bottom surface of the robotic arm 205, and a placement platform 207 being fixedly installed on the upper surface of the base 1. The laser generator 204, in conjunction with the laser cutting head 206, performs laser cutting on the packaging box, avoiding burrs and other phenomena caused by traditional tool punching, thereby improving the punching quality;

[0037] A photoelectric positioning component 3 is installed on the top of the base 1.

[0038] As a further definition of the photoelectric positioning component 3 of the present invention, the photoelectric positioning component 3 includes a connecting gear 301, the top end of which is rotatably connected to the inner top wall of the placement platform 207. A rotating motor 302 is fixedly installed on the upper surface of the base 1, and the output end of the rotating motor 302 is fixedly connected to the bottom end of the connecting gear 301. Two rack plates 303 are meshed on the outer surface of the connecting gear 301. A straightening plate 304 is fixedly installed on the side of the two rack plates 303 that are far apart from each other. A straightening plate 304 is fixedly installed on the outer surface of each straightening plate 304. Equipped with rubber pads 305, the rotating motor 302, in conjunction with the connecting gear 301, drives two rack plates 303 to move relative to each other. This allows the straightening plate 304, in conjunction with the rubber pads 305, to correct the position of the packaging box placed on the placement table 207, preventing deviations in the drilling position due to misalignment of the packaging box. A first electric slide rail 306 is fixedly installed on the inner wall of the mounting bracket 201. A second electric slide rail 307 is slidably connected inside the first electric slide rail 306. The second electric slide rail 307 is slidably connected inside... The movable plate 308 has a connecting cylinder 310 and a photoelectric sensor 309 fixedly mounted on its bottom surface. The photoelectric sensor 309 uses a CCD camera to identify the perforated marks on the outer surface of the packaging box. A filter membrane 311 is fixedly mounted on the inner wall of the connecting cylinder 310. The filter membrane 311 is a metal wire grid polarizer that can filter the strong specular reflections of BOPP glossy film, PET laser film, hot stamping foil, and silver / gold cards, eliminating false recognition due to reflections. A laser emitter 312 is fixedly mounted on the outer surface of the movable plate 308. The inner wall of the mounting frame 201 is fixedly mounted with a glass plate 313 and an industrial camera 315. The bottom surface of the glass plate 313 is fixedly mounted with a coordinate axis 314. By setting up a photoelectric positioning component 3, when the device is in use, it first performs a preliminary scanning positioning of the punching position through a photoelectric sensor 309. At the same time, it uses a filter membrane 311 to remove texture noise and perform coordinate recognition of the positioning position, thereby avoiding reflection and scattering interference caused by the printed pattern on the surface of the packaging box, thus ensuring the accuracy of punching positioning.

[0039] A frame 5 is fixedly installed on the bottom surface of the base 1. Two sets of casters 6 are fixedly installed on the bottom surface of the frame 5. The installation of the frame 5 and the casters 6 makes it convenient for workers to move the device, thereby increasing the ease of movement of the device.

[0040] Each rack plate 303 has a slider 7 fixedly installed on its upper surface. The inner top wall of the placement platform 207 has two grooves 8. Each slider 7 is slidably connected inside the groove 8. The installation of the slider 7 and the groove 8 restricts the movement trajectory of the rack plate 303, thereby preventing the rack plate 303 from deviating from the movement trajectory when moving, and thus ensuring the stability of the movement of the rack plate 303.

[0041] Each correction plate 304 has a pulley 9 fixedly installed on its bottom surface. The outer surface of each pulley 9 is slidably connected to the upper surface of the base 1. The installation of the pulley 9 plays a role in stabilizing the correction plate 304 and preventing the correction plate 304 from shaking when moving.

[0042] The specific implementation method of this embodiment is as follows: The worker turns on the controller 203 to make the device perform a self-test. After confirming that there are no faults or alarms, the equipment enters the standby state. Then, the worker presets the drilling parameters through the controller 203 to match the material and processing requirements of the current cultural and creative packaging box. Then, the worker places the packaging box with the pre-set indentation and drilling marks on the placement platform 207. Then, the worker starts the rotating motor 302. The power provided by the rotating motor 302 drives the connecting gear 301 to rotate, so that the connecting gear 301 synchronously drives the rack plates 303 on both sides to move relative to each other. While the rack plates 303 are moving, they drive the upper slider 7 to slide smoothly along the sliding groove 8 on the inner top wall of the placement platform 207, thereby driving the straightening plates 304 on both sides to move closer to the center of the packaging box. At the same time, the pulley 9 on the bottom surface of the straightening plate 304 slides on the upper surface of the base 1 to reduce the friction of movement. The rubber pad 305 on the outside of the straightening plate 304 flexibly contacts the packaging box to avoid scratching the printed pattern on the surface. At the same time, the packaging box is accurately centered and straightened, completing the initial straightening of the workpiece.

[0043] The first electric slide rail 306 and the second electric slide rail 307 on the inner wall of the mounting bracket 201 drive the moving plate 308 to perform planar displacement, so that the photoelectric sensor 309 at the bottom of the moving plate 308 can identify the perforation mark on the packaging box. During this process, the filter membrane 311 on the inner wall of the connecting cylinder 310 automatically removes reflected noise and scattering interference generated by the printing pattern, texture, and hot stamping process, and retains only the effective positioning signal. When the photoelectric sensor 309 identifies the perforation mark, it emits a light spot onto the glass plate 313 through the laser emitter 312. At the same time, the industrial camera 315 collects the corresponding image of the coordinate axis 314 on the glass plate 313 and the positioning point of the packaging box in real time, and transmits the X / Y axis coordinate data of the positioning point to the controller 203 in real time. The controller 203 records and locks the initial positioning coordinates of the photoelectric sensor, thus completing the initial positioning of the photoelectric sensor.

[0044] Example 2: Please refer to Figure 1 , Figure 5 and Figures 7-9 The present invention provides a technical solution: a photoelectric positioning punching machine for cultural and creative packaging boxes. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A physical positioning component 4 is provided above the base 1.

[0045] As a further definition of the physical positioning component 4 of the present invention, the physical positioning component 4 includes a third electric slide rail 401, the outer surface of which is fixedly connected to the inner wall of the mounting frame 201. A fourth electric slide rail 402 is slidably connected inside the third electric slide rail 401. A connecting frame 403 is slidably connected inside the fourth electric slide rail 402. A threaded rod 404 is rotatably connected inside the connecting frame 403. A rotary motor 405 is fixedly mounted on the outer surface of the connecting frame 403. The output end of the rotary motor 405 is fixedly connected to one end of the threaded rod 404. Two fixing plates 406 are threadedly connected to the outer surface of the threaded rod 404. The distance that the right fixing plate 406 moves to the rightmost side of the connecting frame 403 is the same as the distance between the two fixing plates 406, so that when the right fixing plate 406 moves to the rightmost side, the left fixing plate 406 moves to the initial position of the other fixing plate 406. The bottom surface of one of the fixing plates 406 is fixedly connected to the upper surface of the robot arm 205. Two electric push rods 407 are fixedly installed on the bottom surface of another fixed plate 406. The telescopic ends of the two electric push rods 407 are jointly fixedly installed on a placement plate 408. Two sets of connecting springs 409 and a pressure sensor 410 are respectively fixedly installed on the bottom surface of the placement plate 408. The bottom ends of the two sets of connecting springs 409 are jointly fixedly installed on a mounting plate 411. A probe 412 is fixedly installed on the bottom surface of the mounting plate 411. By setting a physical positioning component 4, the device moves the probe 412 to the position based on the coordinate point identified by the photoelectric positioning component 3. The probe 412 moves near the coordinate point, and the pressure sensor 410 monitors whether the probe 412 descends during its movement on the outer surface of the packaging box, thereby identifying the indentation at the punching position. This assists the photoelectric positioning component 3 in further identifying the punching position, allowing the device to be further positioned physically, thus further avoiding reflection and scattering interference caused by the printed patterns on the surface of the packaging box.

[0046] Two slide rods 10 are fixedly installed on the inner wall of the connecting frame 403. The inner wall of each fixed plate 406 is slidably connected to the outer surface of the slide rod 10. The installation of the slide rod 10 restricts the movement trajectory of the fixed plate 406, thereby preventing the fixed plate 406 from rotating during movement and ensuring the stability of the movement of the fixed plate 406.

[0047] Two sets of electric cylinders 11 are fixedly installed on the inner wall of the connecting frame 403. A connecting block 12 is fixedly installed on the telescopic end of each electric cylinder 11. A fixing spring 13 is fixedly installed on the bottom surface of each connecting block 12. A pressing wheel 14 is fixedly installed on the bottom end of each fixing spring 13. The power provided by the electric cylinder 11, in conjunction with the fixing spring 13, presses the pressing wheel 14 onto the packaging box, thereby playing a pressing and limiting role on the packaging box.

[0048] Each connecting block 12 has a telescopic column 15 fixedly installed on its bottom surface. The telescopic end of each telescopic column 15 is fixedly connected to the upper surface of the pressing wheel 14. The installation of the telescopic column 15 restricts the movement trajectory of the pressing wheel 14, thereby preventing the pressing wheel 14 from deviating from its movement trajectory when moving, and thus ensuring the stability of the movement of the pressing wheel 14.

[0049] Two sets of telescopic rods 16 are fixedly installed on the bottom surface of the mounting plate 408. The telescopic end of each telescopic rod 16 is fixedly connected to the upper surface of the mounting plate 411. The installation of the telescopic rods 16 plays a role in restricting the movement trajectory of the mounting plate 411, thereby ensuring the stability of the movement of the mounting plate 411.

[0050] The specific implementation of this embodiment is as follows: After the initial positioning is completed, the first electric slide rail 306, in conjunction with the second electric slide rail 307, drives the moving plate 308 back to its original position. Then, the third electric slide rail 401, in conjunction with the fourth electric slide rail 402, quickly moves the connecting frame 403 to directly below the coordinate point of the photoelectric positioning, ensuring that the position of the probe 412 corresponds to the positioning coordinate. At the same time, the power provided by the electric cylinder 11 drives the connecting block 12 to move downward, so that the fixing spring 13 cooperates with the telescopic column 15, causing the pressing wheel 14 to elastically press the edge of the packaging box, preventing the workpiece from shifting during drilling. Then, the power provided by the electric push rod 407 drives the placement plate 408 to move downward, so that the probe 412 flexibly contacts the surface of the packaging box. The connecting spring 409 provides buffering force, and the telescopic rod 16 ensures that the probe 412 is vertical and not tilted. Thus, under the combined action of the first electric slide rail 306 and the second electric slide rail 307, the connecting plate 402 moves downward, causing the probe 412 to flexibly contact the surface of the packaging box. The connecting spring 409 provides buffering force, and the telescopic rod 16 ensures that the probe 412 is vertical and not tilted. The probe 412 makes a small circular movement around the coordinate point to physically identify the indentation. When the probe 412 touches the pre-set perforation indentation on the packaging box, the probe 412 sinks slightly, and the pressure sensor 410 detects the sudden pressure change. The controller 203 immediately confirms that the point is the final perforation reference point and completes the physical verification positioning. After positioning is completed, the controller 203 controls the rotary motor 405 to run. The power provided by the rotary motor 405, together with the threaded rod 404, drives the fixed plate 406 to move, so that the laser cutting head 206 moves to the initial position of the probe 412. At the same time, the final positioning coordinates are transmitted to the robot arm 205, and the laser generator 204 is started, so that the robot arm 205 drives the laser cutting head 206 at the bottom to move quickly to the final perforation reference point and perform laser perforation according to the preset parameters, thereby ensuring the accuracy of the perforation positioning of the device and avoiding interference from reflected light.

[0051] Specifically, when using this device:

[0052] First, the worker turns on the controller 203 to enable the device to perform a self-check. After confirming that there are no faults or alarms, the equipment enters standby mode. Then, the worker presets the drilling parameters through the controller 203 to match the material and processing requirements of the current cultural and creative packaging box. The worker then places the packaging box with the pre-set indentation and drilling marks on the placement platform 207. Then, the worker starts the rotating motor 302, which drives the connecting gear 301 to rotate. This causes the connecting gear 301 to synchronously drive the rack plates 303 on both sides to move relative to each other. As the rack plates 303 move, they drive the upper slider 7 to slide smoothly along the slide groove 8 on the inner top wall of the placement platform 207. This causes the straightening plates 304 on both sides to move closer to the center of the packaging box. At the same time, the pulleys 9 on the bottom of the straightening plates 304 slide on the upper surface of the base 1 to reduce friction. The rubber pads 305 on the outer side of the straightening plates 304 flexibly contact the packaging box to avoid scratching the printed patterns on the surface. This accurately centers and straightens the packaging box, completing the initial straightening of the workpiece.

[0053] Then, the first electric slide rail 306 and the second electric slide rail 307 on the inner wall of the mounting frame 201 drive the moving plate 308 to perform planar displacement, so that the photoelectric sensor 309 at the bottom of the moving plate 308 can identify the perforation mark on the packaging box. During this process, the filter membrane 311 on the inner wall of the connecting cylinder 310 automatically removes the reflected noise and scattering interference generated by the printing pattern, texture, and hot stamping process, and retains only the effective positioning signal. When the photoelectric sensor 309 identifies the perforation mark, it emits a light spot onto the glass plate 313 through the laser emitter 312. At the same time, the industrial camera 315 collects the corresponding image of the coordinate axis 314 on the glass plate 313 and the positioning point of the packaging box in real time, and transmits the X / Y axis coordinate data of the positioning point to the controller 203 in real time. The controller 203 records and locks the initial positioning coordinates of the photoelectric sensor, and completes the initial positioning of the photoelectric sensor.

[0054] Furthermore, after the initial positioning is completed, the first electric slide rail 306, in conjunction with the second electric slide rail 307, moves the moving plate 308 back to its original position. Then, the third electric slide rail 401, in conjunction with the fourth electric slide rail 402, quickly moves the connecting frame 403 to directly below the coordinate point of the photoelectric positioning, ensuring that the position of the probe 412 corresponds to the positioning coordinates. At the same time, the power provided by the electric cylinder 11 moves the connecting block 12 downward, so that the fixing spring 13 cooperates with the telescopic column 15, causing the pressing wheel 14 to elastically press against the edge of the packaging box, preventing the workpiece from shifting during drilling. Then, the power provided by the electric push rod 407 moves the placement plate 408 downward, so that the probe 412 flexibly contacts the surface of the packaging box. The connecting spring 409 provides buffering force, and the telescopic rod 16 ensures that the probe 412 is vertical and does not tilt. Thus, under the combined action of the first electric slide rail 306 and the second electric slide rail 307, the probe 412... 2. The probe 412 makes a small circular movement around the coordinate point to physically identify the indentation. When the probe 412 touches the pre-set perforation indentation on the packaging box, the probe 412 sinks slightly. The pressure sensor 410 detects the sudden pressure change, and the controller 203 immediately confirms that the point is the final perforation reference point, completing the physical verification and positioning. After positioning is completed, the controller 203 controls the rotary motor 405 to run. The power provided by the rotary motor 405, together with the threaded rod 404, drives the fixed plate 406 to move, so that the laser cutting head 206 moves to the initial position of the probe 412. At the same time, the final positioning coordinates are transmitted to the robot arm 205, and the laser generator 204 is started, so that the robot arm 205 drives the laser cutting head 206 at the bottom to move quickly to the final perforation reference point and perform laser perforation according to the preset parameters, thereby ensuring the accuracy of the perforation positioning of the device and avoiding interference from reflected light.
