Description

Technical Field

[0001] The utility model relates to the technical field of automatic punching, in particular to a visual automatic punching machine. Background Art

[0002] In today's printing industry, punching plays a crucial role in the entire production process. Traditionally, punching relies heavily on manual labor, with workers using simple tools like punches and awls to create holes in various printing materials, including paper, plastic film, and fabric. This method has significant limitations.

[0003] From an efficiency perspective, manual punching is extremely slow. A skilled worker working continuously might only complete a few hundred holes per hour. In large-scale printing production, which often requires punching tens of thousands of printed materials, manual punching efficiency falls far short of production needs, significantly slowing down overall production progress.

[0004] In terms of precision, manual punching relies primarily on the worker's experience and visual judgment, making it difficult to achieve high consistency in hole placement, size, and spacing. Even experienced workers are subject to errors. This lack of precision can negatively impact subsequent processing steps such as binding and splicing, reducing the overall quality of printed products. Furthermore, due to the instability of manual operation, the holes punched by different workers can vary significantly, making it difficult to ensure product consistency.

[0005] Furthermore, prolonged manual drilling can easily lead to worker fatigue, increasing the risk of operational errors. For example, problems such as missed holes, duplicate holes, or large deviations in hole placement can occur. Furthermore, the manual drilling process requires workers to constantly repeat the same movements, which can easily lead to occupational health issues such as muscle strain.

[0006] With the rapid development of the printing industry, market demands for production efficiency and product quality continue to rise. While some automated punching equipment has emerged on the market, most of these devices have shortcomings. Some equipment has complex structures and is difficult to operate and maintain, requiring specialized technicians to operate and maintain it, increasing the company's labor costs. Some equipment has a single function and can only punch holes in specific types of printed materials, failing to meet the diverse production needs of printing companies. Other equipment can easily damage printed materials during the punching process, such as paper tearing and plastic film deformation, affecting the appearance and performance of printed products. Furthermore, some automated punching equipment is expensive, making the investment cost prohibitive for small and medium-sized printing companies.

[0007] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-5 In an embodiment of the present utility model, a visual automatic punching machine includes an organism 1, an image acquisition device 2, a punching device 3, and a control system. A frame 4 is fixedly provided on the workbench of the organism 1. The image acquisition device 2 is arranged at the upper end of the frame 4 and is used to acquire image information of an object to be punched and transmit the image information to the control system. The punching device 3 is installed on the frame 4 and its action is controlled by the control system to perform a punching operation on the object to be punched. The control system receives the image information transmitted by the image acquisition device 2, analyzes and processes it, and controls the punching device 3 to perform punching.

[0030] The punching device 3 includes a first power member 5 and a connected punching head 6, and a second power member 7 and a connected pressure block 8. The pressure block 8 corresponds to the punching head 6, and a clearance opening 9 is provided along the end surface of the pressure block 8 to cooperate with the punching head 6, so that the two sides and the rear side of the pressure block 8 form a pressing part that acts on the object to be punched, wherein the pressing parts located on both sides of the pressure block 8 are connected to the second power member 7 through an elastic member 10.

[0031] In the technical solution of the present invention, the image acquisition device 2 is located at the upper end of the frame 4 and usually adopts a high-definition camera, which can perform all-round image acquisition of the object to be punched placed on the workbench of the body 1 from different angles. These cameras have high resolution and high frame rate, ensuring that clear and accurate image information can be captured; the collected image information is transmitted to the image processor in the control system in real time. The image processor uses advanced image processing algorithms to first pre-process the image, including operations such as denoising and contrast enhancement to improve image quality, and then identifies key features such as the position, shape, and size of the object to be punched through a feature extraction algorithm. For example, for paper-type printed materials, the outline of the paper can be determined by an edge detection algorithm; for printed materials with specific patterns, the position where the holes need to be punched can be found by a template matching algorithm;

[0032] The punching device 3 is mainly composed of a first power member 5, a punching head 6, a second power member 7 and a pressure block 8. The first power member 5 is usually a motor or a pneumatic device, which can provide strong power to drive the punching head 6 to perform the punching operation. The material and shape of the punching head 6 are selected according to different punching requirements to ensure that clean and neat holes can be punched on the printed material; the second power member 7 can also be a motor or a pneumatic device, which is used to drive the pressure block 8 to press the object to be punched. The design of the pressure block 8 takes into account the cooperation with the punching head 6. The clearance opening 9 opened on its end face corresponds to the punching head 6, so that the punching head 6 can accurately pass through the clearance opening 9 to punch the object. When the second power member 7 drives the pressing block 8 to press down, the pressing parts formed on both sides and the rear side of the pressing block 8 will act on the object to be punched, fixing it stably on the workbench to prevent the object from moving during the punching process; the pressing parts on both sides of the pressing block 8 are connected to the second power member 7 through elastic members 10. The elastic members 10 can be springs or rubber pads, etc., and their function is to provide a certain buffer. When the pressing block 8 is pressed down and contacts the object to be punched, the elastic members 10 will be compressed and generate a certain elastic force. This elastic force can ensure that the pressing part has sufficient pressure on the object to be punched, so that it remains stable during the punching process, and can also avoid excessive pressure causing excessive extrusion and damage to the printing material;

[0033] The control system (such as PLC) is the core of the entire visual automatic punching machine. It receives the image information transmitted by the image acquisition device 2 and analyzes and processes it. According to the processing results, the control system sends precise control instructions to the first power member 5 and the second power member 7 of the punching device 3 to coordinate their actions; when the image processor recognizes the position and characteristics of the object to be punched, the control system will calculate the optimal punching position and punching timing of the punching head 6. Then, the control system first sends an instruction to let the second power member 7 drive the pressure block 8 to press down to press the object to be punched. After the pressing is stable, the control system sends an instruction to let the first power member 5 drive the punching head 6 to perform the punching operation. During the whole process, the control system will monitor the status of the punching device 3 in real time to ensure the accuracy and safety of the punching operation.

[0034] In summary, the application of image acquisition and recognition technology makes the determination of punching position more accurate. Compared with traditional manual punching that relies on experience to judge the position, and the positioning errors that may exist in ordinary automated punching equipment, the visual automatic punching machine can be accurate to millimeters or even higher levels of precision; at the same time, in addition to the punching operation, it can also ensure multiple process positioning in printing; the pressing parts on both sides of the pressing block 8 are connected to the second power part 7 through the elastic part 10. This design can stably press the object to be punched during the punching process. The buffering effect of the elastic part 10 can avoid the pressing part from exerting excessive pressure on the object to be punched, thereby preventing the printed material from being crushed or deformed.

[0035] In the embodiment of the present invention, the lower end surface of the pressing block 8 corresponding to the pressing portion thereof is provided with a flexible pad 11 , and the lower end surface of the flexible pad 11 is provided with a texture 12 .

[0036] A flexible pad 11 is provided on the lower end face of the pressing block 8 corresponding to the pressing portion thereof. When the pressing block 8 is driven by the second power member 7 to press the object to be punched, the flexible pad 11 first contacts the surface of the object. The flexible pad 11 is usually made of a material with a certain elasticity and softness, such as rubber, silicone, etc. This material can deform during the pressing process, so as to better fit the shape of the surface of the object, increase the contact area with the object, and improve the stability of the pressing; the texture 12 provided on the lower end face of the flexible pad 11 further enhances the friction with the surface of the object. These textures 12 can be protrusions, grooves or patterns of various shapes. When the flexible pad 11 contacts the object, the texture 12 will be embedded in the microstructure of the surface of the object to form a mechanical lock to prevent the object from sliding during the punching process.

[0037] In an embodiment of the present utility model, the working surface of the machine body 1 is provided with a positioning area 13 corresponding to the object to be punched, and the pressing block 8 and the punching head 6 are both located above the positioning area 13, wherein a punching slot 14 cooperating with the punching head 6 is provided in the positioning area 13.

[0038] A positioning area 13 is provided on the working surface of the machine body 1 to provide a clear placement location for the object to be punched. This positioning area 13 can be distinguished by a specific shape, mark or other means, so that the operator can quickly and accurately place the object to be punched in the correct location;

[0039] A punching slot 14 cooperating with the punching head 6 is provided in the positioning area 13. When the object to be punched is placed in the positioning area 13, the punching slot 14 corresponds to the position of the punching head 6, ensuring that the punching head 6 can accurately perform the punching operation at the predetermined position. The depth and shape of the punching slot 14 can be designed according to the requirements of the punching. For example, if a deeper hole needs to be punched, a deeper punching slot 14 can be set to prevent the punching head 6 from damaging the work surface during the punching process. At the same time, the shape of the punching slot 14 can match the shape of the punching head 6 to improve the accuracy and quality of the punching.

[0040] In the embodiment of the present invention, the image acquisition device 2 includes an industrial camera 15 and a light source 16 , and both the industrial camera 15 and the light source 16 are directed toward the punching slot 14 ;

[0041] A fixing seat 17 is fixed in the positioning area 13 , and the punching slot 14 is opened along the end surface of the fixing seat 17 . A diffusion plate 18 for the light source 16 is provided on the fixing seat 17 and in front of the punching slot 14 .

[0042] The image acquisition device 2 is composed of an industrial camera 15 and a light source 16. The industrial camera 15 has the characteristics of high resolution, high frame rate and high sensitivity, and can accurately capture the image information of the object to be punched. The light source 16 provides lighting for the industrial camera 15 to ensure that clear and bright images can be obtained under different environmental conditions. The industrial camera 15 and the light source 16 are both facing the punching slot 14, so that they can be directly aimed at the key parts of the object to be punched to obtain the most accurate image information. By collecting images of the punching slot 14 and the surrounding area, the control system can better analyze the position, shape and characteristics of the object to be punched. , providing a basis for accurate punching; a fixing seat 17 is fixed in the positioning area 13, and the punching slot 14 is opened on the end face of the fixing seat 17. The fixing seat 17 plays the role of supporting and fixing the object to be punched, ensuring that the object remains stable during the punching process; a diffusion plate 18 is provided on the fixing seat 17 and in front of the punching slot 14. The main function of the diffusion plate 18 is to diffuse and homogenize the light emitted by the light source 16. When the light source 16 irradiates the diffusion plate 18, the diffusion plate 18 scatters the light evenly onto the object to be punched, avoiding local overbrightness or overdarkness, thereby improving the quality of image acquisition.

[0043] In an embodiment of the present utility model, a crossbeam 19 is provided in the body 1 and below the fixed seat 17. A connecting piece 20 is installed on one side of the crossbeam 19, and a collecting bucket 21 is detachably connected to the connecting piece 20. The collecting bucket 21 is located directly below the punching slot 14, and the punching slot 14 is set through to form a waste discharge channel.

[0044] A crossbeam 19 is provided in the body 1 to provide a stable support structure for the installation of the collecting bucket 21. The crossbeam 19 usually has sufficient strength and rigidity to withstand the weight of the collecting bucket 21 and the waste generated during the punching process. The connecting piece 20 is used to connect the collecting bucket 21 to the crossbeam 19. The connecting piece 20 can adopt a detachable connection method such as bolts and snaps to facilitate the installation and disassembly of the collecting bucket 21. This design facilitates timely cleaning and replacement of the collecting bucket 21 after it is full of waste; the collecting bucket 21 is located directly below the punching slot 14. When the punching head 6 performs a punching operation in the punching slot 14, the waste generated will fall directly into the collecting bucket 21 through the waste discharge channel formed by the through-set punching slot 14. This design ensures that the waste can be collected in time and avoids waste accumulation on the workbench affecting the punching operation.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
