Description

Technical Field

[0001] This utility model relates to the field of edge defect detection, and more particularly to an edge defect detection device. Background Technology

[0002] Blade edge inspection is a quality control step in the production process.

[0003] Currently, the cutting edge of the circular knife is being inspected to identify defective products and prevent defective products from being released.

[0004] Current inspection methods rely more heavily on the labor input of operators, specifically in the manual wiping of the cutting edge and the visual inspection of the cutting edge and the assessment of the integrity of the circular cutter.

[0005] The above-mentioned operational phenomena mean that operators cannot escape this inefficient mode. At the same time, this visual inspection and manual cleaning method results in relatively weak control over the final product. Problems such as gaps exceeding the standard value, dirt on the surface, and bumps are directly left to the user. Utility Model Content

[0006] To address the aforementioned issues, this invention provides a cutting edge defect detection device that frees up operators' hands, transferring manual labor to machine production and enabling rigorous control over the entire defect detection process.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a cutting edge defect detection device, characterized in that it includes a wiping mechanism, a pattern acquisition mechanism, and a carrier, with the circular blade located on the rotatable carrier. The wiping mechanism includes an extension component that tightens the wiping element to ensure that the wiping area of ​​the wiping element is in full contact with the cutting edge and the blade. The pattern acquisition mechanism includes a pattern acquisition unit that provides pattern data to a computer for acquiring the pattern features of the cutting edge and the blade after wiping.

[0008] The beneficial effects of this utility model are:

[0009] This utility model's edge defect device first provides an extension component suitable for the wiping piece, used to stretch the wiping piece so that it is ready for wiping. After using the wiping piece, it directly contacts the edge and blade on the carrier. The carrier rotates, and the wiping piece thoroughly wipes the edge and blade. No manual operation is required throughout the entire process. At the same time, this carrier rotation wiping method provides more rotations per unit time, resulting in better cleaning effect. The pattern acquisition mechanism used after cleaning captures the entire edge and blade image. After the pattern acquisition unit outputs data to the computer, the computer's pre-set defect comparison software performs defect detection. The entire process saves a lot of labor costs, prevents missed detections due to personnel fatigue, and significantly improves the overall detection efficiency.

[0010] The extension component is designed based on the application of the wiping component to the non-woven fabric in the flat state of the circular blade, ensuring that the wiping area of ​​the wiping component is in full contact with the blade edge and the blade body.

[0011] The stretching component includes at least two spaced-apart turntables on which the nonwoven fabric is distributed. The turntables stretch the nonwoven fabric taut. At the same time, the two turntables also unwind and rewind the nonwoven fabric. While wiping, the nonwoven fabric with dust is also collected and processed. From the perspective of use, the time to enter the nonwoven fabric rewinding stage is very fast. In other words, the corresponding structure is very compact and has a higher space utilization rate.

[0012] The extension component also includes a pressure block and an assembly plate. The pressure block and the turntable are set on the assembly plate. The pressure block is located below the turntable and on the movement path of the nonwoven fabric, so that the movement path of the nonwoven fabric changes as it moves along the bottom surface of the pressure block. During wiping, the wiping area of ​​the nonwoven fabric is limited to the part below the pressure block. The purpose of this design is to achieve the effect of raising the turntable. Under the effect of the height difference, interference between the turntable and the carrier or machine platform can be avoided.

[0013] The aforementioned machine is the supporting part of this utility model. The wiping mechanism also includes a first linear moving mechanism. The first linear moving mechanism provides multi-dimensional spatial position changes to drive the extension component to move. It can adapt to different types of circular blades, such as those with different thicknesses and diameters.

[0014] The vehicle is located on the machine platform, which has a second linear movement mechanism and a rotating mechanism built in it. The rotating mechanism is located on the movable end of the second linear movement mechanism and drives the vehicle to rotate.

[0015] The circular cutter has an inner annular surface, and the carrier includes a frustum that fits the inner annular surface. The circular cutter is fitted onto the carrier via the frustum.

[0016] Regarding the pattern acquisition mechanism, it includes a third linear movement mechanism and a light-sensing compensation mechanism. The pattern acquisition unit is a camera, which is set on the output end of the third linear movement mechanism. The blade area is a slope, which requires the light-sensing compensation mechanism to provide supplementary light to the area so that the outline of the slope can be clearly expressed, which is beneficial for the computer to capture the outline more easily in the later stages.

[0017] As mentioned earlier regarding the size of the circular blade, the light-sensing compensation mechanism includes a bottom light source, a bracket, a pull rod, and a fourth linear movement mechanism. The bracket is L-shaped and connected to the pull rod. After the pull rod is installed into the fourth linear movement mechanism, the bracket is located below the carrier and has a surface parallel to the carrier. The bottom light source is set on the surface of the bracket, and the illumination range of the bottom light source covers the blade and cutting edge of the circular blade. The purpose of this design is to achieve avoidance of interference between the bottom light source and the carrier. It should be noted that the camera only changes its vertical position, while the bottom light source needs to be close to the blade to express the contour line of the blade's tilt and the characteristics of the cutting edge more clearly. When a small-sized circular blade is placed on the carrier, this means that the carrier needs to move a longer distance. After the cutting edge and blade reach the acquisition area, the rotating shaft supporting the carrier collides with the bracket (when detecting a large-sized circular blade, the cutting edge and blade reach the acquisition area relatively earlier, so the carrier needs to move a relatively shorter distance). By relying on the use of the fourth linear movement mechanism, the spatial position of the bottom light source can be changed, which can prevent interference between the rotating shaft and the bracket.

[0018] It should be noted that it also includes a lens barrel and a projection light source. The upper end of the lens barrel is connected to the acquisition end of the camera. The side of the lens barrel is provided with an incident end, and the projection light source is connected to the incident end. The bottom of the lens barrel faces the circular knife. Inside the lens barrel is a reflecting prism opposite to the incident light. The reflecting prism has an inclined angle that guides the incident light to the bottom of the lens barrel. The incident light is projected onto the circular knife to illuminate it.

[0019] The aforementioned linear movement mechanism is existing technology, and its structure will not be described in detail here.

[0020] In addition, a servo motor is also provided on the assembly tray, which drives the turntable used for winding the nonwoven fabric to rotate.

[0021] It should also be noted that the inner ring surface of the circular cutter may have different dimensions. For example, the diameter of the inner ring surface of the circular cutter may be less than the diameter of the frustum. The surface of the frustum includes a mounting groove and an auxiliary component that matches the mounting groove. The mounting groove has an insertion hole. After the circular cutter is fitted onto the auxiliary component, the auxiliary component is inserted into the insertion hole. Attached Figure Description

[0034] Please see Figure 1-12 As shown, this utility model is a cutting edge defect detection device. In this specific embodiment, the cutting edge 1a is located at the outer edge of the circular knife 1. This utility model detects the cutting edge 1a at the outer edge of the circular knife 1.

[0035] This utility model includes an organic platform 7 and three parts disposed on the platform 7. The three parts include a wiping mechanism 2, a pattern acquisition mechanism 3, and a moving mechanism 4.

[0036] The wiping mechanism 2 cleans the cutting edge 1a and the blade 1b, removing dust from them, and fully highlighting the surface features of the cutting edge 1a and the blade 1b during the subsequent integrity inspection of the cutting edge 1a and the blade 1b.

[0037] The pattern acquisition mechanism 3 completely acquires the patterns of the blade edge 1a and the blade body 1b so that they can be compared by computer later.

[0038] The moving mechanism 4 transports the circular blade 1 from the wiping mechanism 2 to the pattern acquisition mechanism 3 via the carrier 5. The circular blade 1 is located on the rotatable carrier 5. The wiping mechanism 2 includes an extension member 21 that tightens the wiping member 6 to ensure that the wiping area of ​​the wiping member 6 is in full contact with the cutting edge 1a and the blade 1b. The pattern acquisition mechanism 3 includes a pattern acquisition unit that provides pattern data to the computer for acquiring the pattern features of the cutting edge 1a and the blade 1b after wiping.

[0039] The beneficial effects of this utility model are:

[0040] This utility model's edge defect device first provides an extension component 21 suitable for the wiping component 6, used to stretch the wiping component 6, making it usable for wiping. After using the wiping component 6, it directly contacts the cutting edge 1a and blade 1b on the carrier 5. The carrier 5 rotates, and the wiping component 6 thoroughly wipes the cutting edge 1a and blade 1b. Throughout the process, no manual operation is required. At the same time, this method of wiping by rotating the carrier 5 provides more rotations per unit time, resulting in better cleaning effect. The pattern acquisition unit used after cleaning captures the entire image of the cutting edge 1a and blade 1b. After the pattern acquisition unit outputs data to the computer, the defect detection is performed by the pre-set defect comparison software in the computer. The entire process saves a lot of labor costs, prevents missed detections due to personnel fatigue, and significantly improves the overall detection efficiency.

[0041] The extension component 21 is designed based on the application of the wiping component 6 as non-woven fabric in the flat state of the circular blade 1, ensuring that the wiping area of ​​the wiping component 6 is in full contact with the cutting edge 1a and the blade body 1b.

[0042] The stretching component 21 includes at least two spaced-apart turntables 21a, in which the nonwoven fabric is distributed. The turntables 21a stretch the nonwoven fabric taut. At the same time, the two turntables 21a also unwind and rewind the nonwoven fabric. While wiping, the nonwoven fabric with dust is also collected and processed. From the perspective of use, the time to enter the nonwoven fabric rewinding stage is very fast. In other words, the corresponding structure is very compact and has a higher space utilization rate.

[0043] The extension component 21 also includes a pressure block 21b and an assembly plate 21c. The pressure block 21b and the turntable 21a are arranged on the assembly plate 21c. The pressure block 21b is located below the turntable 21a and on the movement path of the nonwoven fabric, so that the movement path of the nonwoven fabric changes as it moves along the bottom surface of the pressure block 21b. During wiping, the wiping area of ​​the nonwoven fabric is limited to the part below the pressure block 21b. The purpose of this design is to achieve the effect of raising the turntable 21a. Under the effect of the height difference, interference between the turntable 21a and the carrier 5 and the machine platform 7 can be avoided.

[0044] The aforementioned machine base 7 is the load-bearing part of this utility model. The wiping mechanism 2 also includes a first linear moving mechanism. The first linear moving mechanism provides multi-dimensional spatial position changes to drive the extension component 21 to move. It can adapt to different types of circular blades 1, such as those with different thicknesses and diameters.

[0045] The vehicle 5 is located on the machine base 7, which has a second linear movement mechanism and a rotating mechanism built into it. The rotating mechanism is located on the movable end of the second linear movement mechanism and drives the vehicle 5 to rotate.

[0046] The circular cutter 1 has an inner ring surface, and the carrier 5 includes a frustum 52 adapted to the inner ring surface. The circular cutter 1 is fitted onto the carrier 5 through the frustum 52.

[0047] The inner ring surface of the circular cutter 1 may have different sizes. For example, the diameter of the inner ring surface of the circular cutter 1 is less than the diameter of the frustum 52. The surface of the frustum 52 includes a mounting groove 51 and an auxiliary component 53 that matches the mounting groove 51. The mounting groove 51 is provided with an insertion hole 51a. The circular cutter 1 is fitted onto the auxiliary component 53, and the auxiliary component 53 is inserted into the insertion hole 51a.

[0048] Regarding the pattern acquisition mechanism 3, the pattern acquisition mechanism 3 includes a third linear movement mechanism and a light-sensing compensation mechanism. The pattern acquisition unit is a camera 31, which is set on the output end of the third linear movement mechanism. The blade 1b is a slope, which requires the light-sensing compensation mechanism to supplement the light to this area so that the outline of the slope can be clearly expressed, which is beneficial for the computer to capture the outline more easily in the later stage.

[0049] As mentioned earlier regarding the size of the circular knife 1, the light-sensing compensation mechanism includes a bottom light source 32, a bracket 33, a pull rod 34, and a fourth linear movement mechanism. The bracket 33 is L-shaped and connected to the pull rod 34. After the pull rod 34 is installed into the fourth linear movement mechanism, the bracket 33 is located below the carrier 5 and has a surface parallel to the carrier 5. The bottom light source 32 is set on the surface of the bracket 33, and the illumination range of the bottom light source 32 covers the blade 1b and the cutting edge 1a of the circular knife 1. This design aims to achieve the avoidance of the bottom light source 32. It should be noted that the camera 31 only changes its vertical position, while the bottom light source 32 needs to be close to the blade 1b to more clearly express the tilted contour line of the blade 1b and the features of the cutting edge 1a. When a small-sized circular knife 1 is placed on the carrier 5, this means that the travel distance of the carrier 5 needs to be longer. After the cutting edge 1a and the blade 1b reach the collection area (e.g., Figure 4 As shown, moving in the X direction), the rotating spindle 100 supporting the carrier 5 collides with the bracket 33 (when detecting the large-sized circular knife 1, the cutting edge 1a and the blade 1b of the circular knife 1 arrive at the collection area earlier, so the travel distance that the carrier 5 needs to move is relatively short). By relying on the use of the fourth linear movement mechanism, the spatial position of the bottom light source 32 can be changed, which can prevent interference between the rotating spindle 100 and the bracket 33.

[0050] It should be noted that it also includes a lens barrel 35 and a projection light source 36. The upper end of the lens barrel 35 is connected to the acquisition end of the camera 31. The side of the lens barrel 35 is provided with an incident end. The projection light source 36 is connected to the incident end. The bottom of the lens barrel 35 faces the circular knife 1. The lens barrel 35 is provided with a reflecting prism opposite to the incident light. The reflecting prism has an inclined angle to guide the incident light to the bottom of the lens barrel 35. The incident light is projected onto the circular knife 1 to illuminate the circular knife 1.

[0051] The aforementioned linear movement mechanism and rotary mechanism are existing technologies, and their structures will not be described in detail here.

[0052] In addition, a servo motor 21d is provided on the assembly plate 21c, which drives the turntable 21a for winding up the nonwoven fabric to rotate.

[0053] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
