Description

Technical Field

[0001] This utility model relates to the field of cutting and laser engraving equipment, and in particular to a cutting and laser engraving equipment for coffee strainers. Background Technology

[0002] As a common brewing device, the size, position, and uniformity of the holes in the coffee filter directly affect the extraction efficiency and taste of coffee. Therefore, high-precision cutting and laser engraving are required during the production process.

[0003] In existing production processes, the processing of coffee funnels is typically done semi-automatically. Workpiece positioning often relies on fixed mechanical fixtures or manual alignment, which has significant limitations. Mechanical fixtures wear down over time, leading to a gradual decrease in positioning accuracy; while manual alignment is not only inefficient but also highly susceptible to human error due to operator fatigue or negligence, making it difficult to guarantee consistent product positioning in mass production.

[0004] More importantly, traditional production lines generally lack effective online quality inspection after the cutting and laser engraving processes are completed. Product quality control usually relies on manual sampling, which cannot comprehensively check the quality of every product. This can easily lead to defective products with out-of-tolerance dimensions or defects being mixed in with qualified products and entering the market. At the same time, sampling is lagging behind. When equipment malfunctions and causes a continuous production of defective products, it is impossible to detect and stop the machine for adjustment in time, resulting in a large amount of material waste and increased production costs.

[0005] Existing technologies have failed to effectively integrate high-precision processing positioning with real-time online quality inspection. The processing and quality inspection processes are disconnected, resulting in a low overall level of automation in coffee filter processing, difficulty in ensuring product quality consistency, and a need to improve production efficiency. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a coffee filter cutting and laser engraving device, which aims to improve the problems of unstable processing accuracy due to reliance on mechanical or manual positioning, and uncontrollable product qualification rate due to the lack of online quality inspection and automatic sorting.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please refer to Figures 1 to 12This utility model provides a coffee funnel cutting and laser engraving device, which aims to solve the problems of low production efficiency and product qualification rate in the existing technology, which rely on manual positioning, have unstable accuracy, and lack online quality inspection and automatic sorting.

[0036] The coffee filter cutting and laser engraving equipment includes a mounting box 3 and an assembly mechanism 4 located inside the mounting box 3; the conveying mechanism 7, laser cutter 9, laser engraving machine 10, handling robot mechanism 6 and vision inspection mechanism 5 are all integrated and installed on the assembly mechanism 4, while the mounting box 3 provides support and protection for the entire equipment.

[0037] The visual inspection mechanism 5 includes a first visual camera 501, a second visual camera 502, a light source 503, and an inspection fixture 505, which are fixedly connected in the mounting box 3. The dual-camera system forms a closed-loop control scheme for pre-processing positioning and post-processing inspection.

[0038] Specifically, the conveying mechanism 7 is equipped with a cutting laser engraving fixture 702 for carrying the coffee funnel to be processed. The first vision camera 501 is configured to face the cutting laser engraving fixture 702. The light source 503 is set next to the first vision camera 501 and faces the cutting laser engraving fixture 702. Under the stable illumination provided by the light source 503, the first vision camera 501 captures an image of the coffee funnel located on the cutting laser engraving fixture 702 to obtain its precise planar coordinates and attitude information, providing high-precision positioning data for the subsequent operation of the laser cutting machine 9 and the laser engraving machine 10.

[0039] The inspection fixture 505 has light-emitting points inside, and its upper surface is covered with an acrylic plate. The built-in light-emitting points form a backlighting effect. When the processed coffee filter is placed on the acrylic plate, the light passes through the holes in the coffee filter, making the outline of the holes clearly visible under high contrast. The second vision camera 502 is configured to face the acrylic plate of the inspection fixture 505 to capture images of the holes illuminated by the backlight. The size and roundness of the holes are calculated through image analysis to determine whether the product is qualified.

[0040] The movement range of the handling robot mechanism 6 covers the cutting laser engraving jig 702 and the inspection jig 505, which is used to accurately and quickly transfer coffee funnels between the processing station and the inspection station. The workpiece to be processed is sent from the loading station 203 to the cutting laser engraving jig 702, and then the processed workpiece is taken away from the cutting laser engraving jig 702 and placed on the inspection jig 505. Finally, the inspected workpiece is sent to the unloading mechanism 8, realizing the efficient material flow of the entire automated process.

[0041] The conveying mechanism 7 provides a platform for the flow of materials in the processing and inspection area. The conveying mechanism 7 includes a conveyor belt 701 and a conveying motor 704 that drives the conveyor belt 701. The cutting and laser engraving fixture 702 is rotatably mounted on the conveyor belt 701 to stably support the coffee funnel during the conveying process. The conveying mechanism 7 also includes a fixture rotary motor 703 that drives the cutting and laser engraving fixture 702 to rotate. After the first vision camera 501 completes the positioning, the fixture rotary motor 703 can adjust the posture of the coffee funnel as needed to match the angle requirements of cutting and laser engraving. To ensure absolute stability during the processing, the visual inspection mechanism 5 also includes a cutting and laser engraving fixing block 11 vertically mounted above the cutting and laser engraving fixture 702, and a cutting and laser engraving fixing cylinder 504 that drives the cutting and laser engraving fixing block 11 to move up and down. Before the cutting and laser engraving process begins, the cutting and laser engraving fixing cylinder 504 is activated, driving the cutting and laser engraving fixing block 11 to press down and fit tightly against the coffee infuser, firmly pressing the coffee infuser onto the cutting and laser engraving fixture 702, effectively preventing workpiece displacement caused by processing impact or vibration.

[0042] The laser cutting machine 9 includes a laser cutting head 904, and a laser generator 901, a cutting screwdriver up-and-down motor 902, and a cutting screwdriver lateral movement motor 903, which are respectively connected to the laser cutting head 904. The laser generator 901 generates the laser required for cutting. The cutting screwdriver up-and-down motor 902 controls the vertical feed and retraction of the laser cutting head 904. The cutting screwdriver lateral movement motor 903 controls the movement of the laser cutting head 904 in the horizontal plane. Through the coordinated control of the three motors, the tip of the laser cutting head 904 can accurately reach any target coordinate point determined by the first vision camera 501.

[0043] The handling robot mechanism 6 includes a horizontal moving motor module 605 that provides a wide range of horizontal movement, an upper and lower cylinder 601 vertically mounted at the output end of the horizontal moving motor module 605, and a handling claw 603 and a vacuum nozzle 604 mounted at the piston rod end of the upper and lower cylinder 601. The horizontal moving motor module 605 drives the entire robot to shuttle between different workstations. The upper and lower cylinder 601 is responsible for lifting and lowering the material to pick up and put down. The handling claw 603 and the vacuum nozzle 604, as end effectors, work together to ensure stable gripping and release of the coffee infuser. In addition, the handling robot mechanism 6 also includes a rotary motor 602 mounted between the upper and lower cylinder 601 and the handling claw 603. The rotary motor 602 drives the handling claw 603 to rotate, thereby flexibly adjusting the posture of the coffee infuser during gripping and placement to adapt to the docking requirements of different workstations.

[0044] Working principle: First, the coffee infusers to be processed are fed into the feeding mechanism 2 via the elevator 1. Under the vibration of the vibrating plate 201, they are arranged in an orderly manner and enter the feeding track 202. When the coffee infusers reach the end of the track, they are blocked by the feeding limit block 207 and detected by the infrared sensor head 206 at the distributing position. Then, the distributing cylinder 205 pushes the distributing fixture 204 to accurately deliver a single coffee infuser to the loading position 203. The handling robot arm 6 then moves. Driven by the transverse motor module 605 and the upper and lower cylinders 601 of the handling mechanism, the handling claw 603 grabs the coffee infusers from the loading position 203 and places them on the cutting laser engraving fixture 702 of the conveying mechanism 7.

[0045] The conveyor motor 704 drives the conveyor belt 701 to transport the cutting and laser engraving fixture 702 carrying the coffee infuser to a position below the first vision camera 501. Under the illumination of the light source 503, the first vision camera 501 takes a picture of the coffee infuser and identifies the precise coordinates of the position to be cut and laser engraved. The conveyor belt 701 continues to transport the cutting and laser engraving fixture 702 to the processing area. The cutting and laser engraving fixing cylinder 504 drives the cutting and laser engraving fixing block 11 to press down and firmly fix the coffee infuser. Based on the received coordinate data, the laser cutting machine 9 controls the laser cutting head 904 to complete the precise cutting through the coordinated action of the cutting screwdriver lateral movement motor 903, the cutting screwdriver up and down motor 902, and the laser generator 901. At the same time, the laser engraving machine 10 also completes the laser engraving operation at the designated position.

[0046] After processing, the fixing mechanism is released, and the handling robot mechanism 6 moves again to remove the processed coffee filter from the cutting laser engraving jig 702 and place it precisely on the inspection jig 505 of the vision inspection mechanism 5. The light-emitting points inside the inspection jig 505 form a clear outline image through the holes of the coffee filter and the acrylic plate, which is captured by the second vision camera 502 above. The system analyzes the image data to determine whether the hole size and roundness are qualified.

[0047] Finally, the handling robot 6 places the inspected coffee infuser onto the discharge conveyor belt 802 of the discharge mechanism 8. The coffee infuser moves forward with the conveyor belt 701 and passes the sensing rod 804. According to the detection result of the second vision camera 502, if the control system determines that it is a defective product, it will trigger the defective product ejection cylinder 803 when the coffee infuser reaches the predetermined position, pushing the defective product into the defective product collection box 801. The qualified products continue to be sent out by the discharge conveyor belt 802 to complete the collection. Through this collaborative action of the vision inspection mechanism 5 and various execution mechanisms, the entire process from feeding, precise positioning and processing to online quality inspection and automatic sorting is fully automated.
