Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and particularly relates to a positioning, detection and coding device for parts after laser cutting processing. Background Art

[0002] In the field of modern industrial manufacturing, laser cutting technology, with its high precision, high speed and good cutting quality, is widely used in the processing procedures of various parts, such as cutting, punching operations, etc. Laser cutting is a processing method that uses a laser beam with a high energy density to focus on the surface of the material, causing the material to quickly melt or vaporize, and then achieving separation. However, a large amount of waste chips in a high-temperature state will be generated during this processing process. These waste chips will inevitably fall or adhere to the surface of the parts, thus forming slag.

[0003] After the parts are processed by laser cutting, subsequent positioning, detection and coding are usually required. In the current industrial production process, the positioning and detection of parts highly rely on industrial cameras to collect images to accurately obtain key information such as the size, shape, and surface defects of the parts; the coding link is to endow the parts with a unique identifier to meet the requirements of product traceability and quality control. However, during the laser cutting process, the high-temperature waste chips fall or spatter on the surface of the parts, and will adhere to the surface of the parts to form slag with different sizes and messy distributions, making it impossible for the parts to be placed stably on the workbench for detection and coding. When the parts are not placed stably, there will be deviations when the industrial camera collects images, and the obtained part contours and detailed features have errors compared with the actual situation. This not only interferes with subsequent detection processes such as size measurement and defect determination based on image analysis, reducing the detection accuracy, but in severe cases, it may misjudge qualified parts as defective products, or mix defective products into the batch of qualified products.

[0004] At the same time, in the coding link, the unstable surface of the parts makes it difficult for the coding equipment to maintain the accurate distance and appropriate angle between the coding head and the parts, and ultimately results in distorted coding, affecting the clarity and readability of the coding, greatly reducing the traceability information of the parts, and not meeting the standards of high-quality production and strict quality control systems, bringing significant obstacles to the coherence of the enterprise production process, product quality assurance and production efficiency improvement. There is an urgent need for a device that can effectively solve the above problems to optimize the entire production link. Summary of the Invention

[0005] The object of the present invention is to provide a positioning, detecting and inkjet coding device for parts after laser cutting. Through the cooperation of the first grinding roller and the second grinding roller, the upper and lower ends of the parts can be ground to remove floating slag, avoiding the situation that the parts cannot be placed stably due to the floating slag, which may lead to deviation in the images collected by the industrial camera and affect the clarity and readability of the inkjet coding.

[0043] Please refer to the attached Figures 1 to 4 shown and Figure 9 shown. This is the first embodiment of the present invention, which provides a positioning, detection, and inkjet coding device for parts after laser cutting machine processing. It includes a housing 10. Feed ports and discharge ports are respectively opened at both ends of the housing 10. And a control module (not shown in the figure) is assembled at one end of the feed port. A first grinding motor 11 and a second grinding motor 12 are assembled at one end of the housing 10 near the feed port. A first grinding roller 13 is fixed to the output end of the first grinding motor 11. A second grinding roller 14 is fixed to the output end of the second grinding motor 12. And the first grinding roller 13 and the second grinding roller 14 are adapted to each other. A conveyor belt assembly 15 is assembled at one end of the housing 10 near the discharge port. Two trusses 16 are assembled inside the housing 10 and above the conveyor belt assembly 15. An inkjet printing assembly 17 and an industrial camera 18 are respectively assembled at one end of the two trusses 16 near the discharge port. The first grinding motor 11 and the control module, the second grinding motor 12 and the control module, the inkjet printing assembly 17 and the control module, and the industrial camera 18 and the control module are all electrically connected by wires. And the inkjet printing assembly 17 is located at one end of the housing 10 near the discharge port. It further includes:

[0044] A first feeding mechanism 20 is provided at one end of the housing 10 near the feed port. And the first grinding motor 11 and the first feeding mechanism 20, as well as the first grinding roller 13 and the first feeding mechanism 20, are all interconnected.

[0045] The second feeding mechanism 30 is assembled at one end of the interior of the housing 10 near the feeding port and is located at the lower end of the first feeding mechanism 20. The first feeding mechanism 20 and the second feeding mechanism 30 are adapted to each other, and both the second grinding motor 12 and the second feeding mechanism 30 and the second grinding roller 14 and the second feeding mechanism 30 are connected to each other. Through the cooperation of the first feeding mechanism 20 and the second feeding mechanism 30, parts can be conveyed in the direction close to the discharging port;

[0046] Two self-rotation driving mechanisms 40 are both assembled at the lower end of the interior of the housing 10 and are respectively located at both ends of the first grinding roller 13. The self-rotation driving mechanism 40 can drive the rod-shaped parts to rotate around their own axis;

[0047] Among them, after the first grinding motor 11 and the second grinding motor 12 are started, the first grinding roller 13 and the second grinding roller 14 can grind the upper end face and the lower end face of the parts.

[0048] It should be noted that moving modules are provided at the upper ends of the trusses 16, and the moving modules and the control module are electrically connected through wires. The trusses 16 and the painting assemblies 17 and the trusses 16 and the industrial cameras 18 are all connected through the moving modules. The moving modules can drive the painting assemblies 17 and the industrial cameras 18 to move in the vertical direction and the horizontal direction. Further, the moving modules are existing mature applications and will not be elaborated further here. In this embodiment, the moving modules are preferably two-axis linear moving modules.

[0049] In this embodiment, during the process of processing parts by laser cutting, such as cutting and punching, high-temperature waste chips will fall or adhere to the surface of the parts to form dross. According to the height of the parts, the distance between the first feeding mechanism 20 and the second feeding mechanism 30 is adjusted by the control unit, so that both the first feeding mechanism 20 and the parts and the second feeding mechanism 30 and the parts can be in contact. The parts are placed between the first feeding mechanism 20 and the second feeding mechanism 30. Through the cooperation of the first feeding mechanism 20 and the second feeding mechanism 30, the parts are moved towards the direction close to the discharge port. The first grinding motor 11 and the second grinding motor 12 are started. The first grinding roller 13 and the second grinding roller 14 are driven to rotate by the first grinding motor 11 and the second grinding motor 12 respectively. When the parts move between the first grinding roller 13 and the second grinding roller 14, through the cooperation of the first grinding roller 13 and the second grinding roller 14, the upper and lower ends of the parts are ground, and the dross on the upper and lower ends of the parts is ground. After grinding, through the cooperation of the first feeding mechanism 20 and the second feeding mechanism 30, the parts are conveyed to the surface of the conveyor belt assembly 15. The conveyor belt assembly 15 drives the parts to pass through the lower ends of the industrial camera 18 and the painting assembly 17 in sequence. When the parts pass through the lower end of the industrial camera 18, the industrial camera 18 collects the images of the parts, and the control unit identifies information such as the size and placement angle of the parts. Then, according to the identified information, the painting assembly 17 codes on the surface of the parts. Through the above scheme, the device can grind the surface of flat parts, remove the dross on the upper and lower ends of the parts, avoid the dross causing the flat parts to be unable to be placed flat, and then cause the industrial camera 18 to be unable to accurately obtain the images of the parts. At the same time, it can also avoid the coding from being distorted and deformed, resulting in the clarity and readability of the coding being affected.

[0050] It should be noted that the above scheme is for flat parts. Among them, flat parts refer to parts with both the upper and lower ends being flat surfaces.

[0051] Among them, during the process of image acquisition of parts by the industrial camera 18 and coding of parts by the painting assembly 17, the moving module can drive the painting assembly 17 and the industrial camera 18 to move, so as to be applicable to parts with different placement angles and shapes, making the device have a good application range.

[0052] It should be noted that the images of the parts are collected by the painting assembly 17, and information such as the size and placement angle of the parts is identified according to the images, mainly relying on industrial image recognition technology. This technology is a mature existing application and will not be elaborated further here.

[0053] Secondly, please refer to again Figure 5 and Figure 6, the first feeding mechanism 20 includes a plurality of first electric cylinders 21, a first bracket 22, a plurality of first feeding rollers 23, a plurality of first pulleys 24, a plurality of first transmission belts 25, and a first feeding motor 26. The plurality of first electric cylinders 21 are all fixed to the upper end inside the housing 10, and the output ends of the first electric cylinders 21 are vertically downward. The first bracket 22 is fixed to the output ends of the plurality of first electric cylinders 21, and the first grinding roller 13 and the first bracket 22 are rotatably connected through a ball bearing. The first grinding motor 11 is fixed to one side of the first bracket 22. The plurality of first feeding rollers 23 are all rotatably connected to the inside of the first bracket 22 through ball bearings, and the plurality of first feeding rollers 23 are respectively distributed at both ends of the first grinding roller 13. The first pulley 24 is fixed to one end of the first feeding roller 23 and located on the other side of the first bracket 22. The plurality of first transmission belts 25 are respectively assembled on the outer sides of two adjacent first pulleys 24. The first feeding motor 26 is fixed to one side of the first bracket 22, and the first feeding motor 26 and the control module are electrically connected through a wire. Among them, one first feeding roller 23 is fixedly connected to the output end of the first feeding motor 26.

[0054] Next, please also refer to Figure 7 As shown in the figure, the second feeding mechanism 30 includes a second bracket 31, a plurality of second feeding rollers 32, a plurality of second pulleys 33, a plurality of second transmission belts 34, and a second feeding motor 35. The second bracket 31 is fixed inside the housing 10 and located at the lower end of the first bracket 22. The second grinding motor 12 is fixed to one side of the second bracket 31. The second grinding roller 14 and the second bracket 31 are rotatably connected through a ball bearing. The plurality of second feeding rollers 32 are all rotatably connected to the inside of the second bracket 31 through ball bearings, and the plurality of second feeding rollers 32 correspond to the plurality of first feeding rollers 23 one by one. The plurality of second pulleys 33 are respectively fixed to one side of the plurality of second feeding rollers 32 and located on the other side of the second bracket 31. The plurality of second transmission belts 34 are respectively assembled on the outer sides of two adjacent second pulleys 33. The second feeding motor 35 is fixed to one side of the second bracket 31, and the second feeding motor 35 and the control module are electrically connected through a wire. Among them, one second pulley 33 is fixedly connected to the output end of the second feeding motor 35.

[0055] It should be noted that the corresponding second feeding roller 32 and the first feeding roller 23 rotate in opposite directions, and after the second feeding roller 32 and the first feeding roller 23 operate, they can move the parts in the direction close to the discharge port.

[0056] In this embodiment, after the laser-cut part is placed between the first feeding roller 23 and the second feeding roller 32 through the feeding port, the first feeding motor 26 and the second feeding motor 35 are started. The first feeding roller 23 and the second feeding roller 32 are driven to rotate respectively by the first feeding motor 26 and the second feeding motor 35, and the part is driven to move towards the direction close to the discharge port by the first feeding roller 23 and the second feeding roller 32. After the part moves between the first grinding roller 13 and the second grinding roller 14, the upper surface and the lower surface of the part are ground by the first grinding roller 13 and the second grinding roller 14 to remove the scum on the upper surface and the upper end of the lower surface of the part. After the part is ground, it is conveyed to the upper end of the conveyor belt assembly 15 through the cooperation of the first feeding roller 23 and the second feeding roller 32. The ground part can be stably placed on the surface of the conveyor belt assembly 15, and then the part is detected and ink-jet coded through the cooperation of the industrial camera 18 and the ink-jet printing assembly 17.

[0057] Secondly, please refer to again Figures 5 to 7 As shown, arc-shaped grinding grooves 19 are formed at one ends on the outer sides of the first grinding roller 13 and the second grinding roller 14, first feeding grooves 27 are formed at one ends on the outer sides of the first feeding roller 23, second feeding grooves 36 are formed at one ends on the outer sides of the second feeding roller 32, and the arc-shaped grinding grooves 19, the first feeding grooves 27 and the second feeding grooves 36 are adapted to each other.

[0058] In this embodiment, when the part is a round rod-shaped part, the round rod-shaped part is placed between the first feeding groove 27 and the second feeding groove 36, and the round rod part is clamped and conveyed through the cooperation of the first feeding groove 27 and the second feeding groove 36. The surface of the round rod is ground by the side wall of the arc-shaped grinding groove 19. During this process, through the cooperation of the first feeding groove 27 and the second feeding groove 36, the round rod-shaped part can be prevented from moving around, so that the device can not only grind flat parts, but also grind round rod-shaped parts, improving the application range of the device.

[0059] Please refer to again Figure 8, the rotation drive mechanism 40 includes a second electric cylinder 41, a guide post 42, a guide sleeve 43, a bottom plate 44, a drive motor 45, a worm 46, a drive wheel 47 and a worm gear 48. The second electric cylinder 41 and multiple guide posts 42 are both fixed inside the housing 10, and the second electric cylinder 41 is located between the multiple guide posts 42. Multiple guide sleeves 43 are respectively slidably connected to the outside of the multiple guide posts 42. The bottom plate 44 is located outside the multiple guide sleeves 43, and the bottom plate 44 is fixedly connected to the output end of the second electric cylinder 41. The drive motor 45 is fixed to the lower end of the bottom plate 44. The worm 46 is fixed to the output end of the drive motor 45, and the worm 46 and the bottom plate 44 are rotatably connected through a ball bearing. The drive wheel 47 is rotatably connected to the upper end of the bottom plate 44, and the drive wheel 47 is adapted to the arc-shaped grinding groove 19. The worm gear 48 is fixed to one side of the drive wheel 47, and the worm 46 and the worm gear 48 are meshed.

[0060] Here, a U-shaped bracket is provided at the upper end of the bottom plate 44, and the drive wheel 47 is rotatably connected inside the U-shaped bracket.

[0061] Furthermore, the second electric cylinder 41 and the control module, and the drive motor 45 and the control module are both electrically connected through wires.

[0062] In this embodiment, when grinding the surface of a round rod-like part, the round rod and the arc-shaped grinding groove 19 are in point contact. The arc-shaped grinding groove 19 cannot completely grind the surface of the round rod part. Start the second electric cylinder 41. Due to the fixed connection between the second electric cylinder 41 and the bottom plate 44, the second electric cylinder 41 drives the bottom plate 44 to move. Due to the rotatable connection between the bottom plate 44 and the drive wheel 47, the bottom plate 44 drives the drive wheel 47 to move synchronously. When the drive wheel 47 is in contact with the surface of the round rod-like part, start the drive motor 45. Due to the fixed connection between the drive motor 45 and the worm 46, the drive motor 45 drives the worm 46 to rotate. Due to the meshing connection between the worm 46 and the worm gear 48 and the fixed connection between the drive wheel 47 and the worm gear 48, the worm 46 drives the worm gear 48 and the drive wheel 47 to rotate synchronously. Since the drive wheel 47 is in contact with the outside of the round rod-like part, the drive wheel 47 drives the round rod-like part to rotate around its own axis, and then the surface of the round rod-like part is ground by the arc-shaped grinding groove 19 to remove the slag adhering to the outside of the part.

[0063] Please refer to again Figure 8 , a distance sensor 49 is fixed inside the bottom plate 44, and the sensing end of the distance sensor 49 is located on the extension direction of the axis of the drive wheel 47.

[0064] Here, it should be noted that the distance between the distance sensor 49 and the control unit, and the distance between the sensing end of the distance sensor 49 and the uppermost end of the drive wheel 47 in the vertical direction is a fixed value.

[0065] In this embodiment, since the diameters of the round bar parts are different, after the round bar parts are placed in the first feeding groove 27 and the second feeding groove 36, the positions of the lowest points of the parts are also different. The driving wheel 47 detects the position of the lowest point of the part, and the control module calculates the distance between the driving wheel 47 and the lowest point of the round bar part. Then, the second electric cylinder 41 drives the driving wheel 47 to move, so that the highest point of the driving wheel 47 can be in close contact with the lowest points of the round bar parts with different diameters.

[0066] In a preferred embodiment, anti-slip bushings are provided on the outer sides of the first feeding roller 23, the second feeding roller 32, and the driving wheel 47. Anti-slip patterns are provided on the outer sides of the anti-slip bushings, and the material of the anti-slip bushings is an elastic material.

[0067] It should be noted that anti-slip bushings are not provided on the inner walls of the first feeding groove 27 and the second feeding groove 36 to prevent the round bar parts from being unable to rotate when they are inside the first feeding groove 27 and the second feeding groove 36.

[0068] In this embodiment, the setting of the anti-slip bushings can increase the friction between the first feeding roller 23 and the parts, the second feeding roller 32 and the parts, and the driving wheel 47 and the parts, facilitating the stable feeding of the parts or driving the parts to rotate.

[0069] The working principle of the present invention is as follows:

[0070] When detecting and inkjet coding parts, if the parts are flat parts, according to the height of the parts, the distance between the first feeding mechanism 20 and the second feeding mechanism 30 is adjusted through the control unit, so that the first feeding roller 23 and the parts and the second feeding roller 32 and the parts can be in contact with each other. Place the parts between the first feeding roller 23 and the second feeding roller 32, start the first feeding motor 26 and the second feeding motor 35, and convey the parts in the direction of the discharge port through the cooperation of the first feeding roller 23 and the second feeding roller 32.
