Description

Technical Field

[0001] The present invention relates to the technical field of printing press blade quality detection devices, and particularly to a blade quality detection device. Background Art

[0002] As a consumable for applying ink and slurry to a carrier, the blade of a printing press has certain requirements for the flatness of the blade edge. Once burrs or pits appear on the blade edge, it will affect the printing effect of the ink and slurry.

[0003] A Chinese patent with the patent number CN108692695A and the patent name of a blade detection device for omnidirectional detection is disclosed in the prior art. Specifically, it discloses a technical solution including a frame, a main control console, and a detection module; the frame has a horizontal workbench; the detection module includes a first X-axis translation sliding seat, a second X-axis translation sliding seat, an up-and-down adjustable blade surface defect detection device, a blade installation unit, a second X-axis translation drive mechanism, a first X-axis translation drive mechanism, a blade flatness detection device, and a blade edge angle and deformation amount detection device; a first X-axis slide rail and a second X-axis slide rail are provided on the horizontal workbench, and the first X-axis translation sliding seat is installed along the first X-axis slide rail, and the second X-axis translation sliding seat is installed along the second X-axis slide rail. The above technology can realize the omnidirectional detection of the blade, so as to understand the various performances and parameter performances of the blade, and timely know whether to replace the tool and perform timely maintenance on the tool. At the same time, the degree of automation is relatively high, which is conducive to improving the detection efficiency.

[0004] During the production and processing of the two side surfaces of the blade, especially at the blade edge, it is inevitable that burrs will appear. In the prior art, it is difficult to accurately capture the burrs attached to the blade surface through visual detection, which to a certain extent affects the detection effect of the blade edge. Summary of the Invention

[0005] The present invention discloses a blade quality detection device, aiming to solve the technical problem that the detection result of the detection device in the prior art is easily affected by external forces and the result is prone to errors and it is difficult to return to the initial state.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A blade quality detection device includes a frame, a blade fixing component, and a visual detection component. The blade fixing component includes a fixing seat installed at the upper end of the frame, and a placement groove for placing the blade is provided on the fixing seat.

[0008] The visual detection component includes a first detection camera and a second detection camera movably installed on the frame. The first detection camera and the second detection camera can reciprocate along one side direction of the frame, and the lenses of the first detection camera and the second detection camera face the two side edges at the upper end of the scraper.

[0009] There are two brackets movably installed on the fixed seat along the width direction of the scraper. The two brackets are respectively located at the two side ends of the scraper. Between the two brackets, two push rods are movably installed. The two push rods are symmetrically distributed with the scraper as the center. When the visual detection component starts to work, the two push rods move towards the scraper direction simultaneously and fit on the side end faces of the scraper, pushing the burrs on the scraper to the two side edges at the upper end of the scraper.

[0010] Further, the notch of the placement groove faces vertically upward and the included angle between the two inner ends in the groove is 90 degrees.

[0011] Further, on both sides of the fixed seat, there is an inclined sliding arm respectively. The sliding arm is arranged at 45 degrees with the fixed seat. The two brackets are respectively installed on the two sliding arms in a guiding manner and reciprocate along the inclined direction of the sliding arm.

[0012] Further, a lever is perpendicularly connected to the side end of each push rod. The two levers are symmetrically distributed with the sliding arm as the center. And each lever always fits on the side end face of the sliding arm. At the same time, an elastic member is arranged between the side of the push rod away from the sliding arm and the fixed seat.

[0013] Further, on the side end face of the sliding arm, there are an expansion part and a downward sliding part arranged successively from bottom to top. The downward sliding part is connected above the expansion part, and the distance between the two downward sliding parts on both sides of the sliding arm is smaller than the distance between the two expansion parts on both sides.

[0014] Further, there are at least two downward sliding parts, and when approaching the upper end of the scraper, the distance between the two downward sliding parts on both sides gradually becomes smaller.

[0015] Further, two driving arms are elastically hinged on the fixed seat. One side of the two driving arms always abuts against the bottom ends of the two brackets respectively. The two driving arms are both sleeved on a driving shaft. The driving shaft is arranged parallel to the scraper and starts to rotate when the first detection camera and the second detection camera move along one side direction of the frame.

[0016] Further, a fixing plate that can vertically move towards the scraper direction is arranged in the fixed seat. A plurality of fixing pins are arranged on the fixing plate. The fixing pins are arranged corresponding to the fixing holes of the scraper and are inserted into the fixing holes of the scraper when the fixing plate approaches the scraper. Among them, the distance between each fixing pin and the scraper is adjustable.

[0017] Further, a driving plate is arranged on one side of the fixing plate. The driving plate is located below the driving shaft, and a tooth groove is formed at the upper end of the driving plate. The driving shaft is always in contact with the fixing plate and its outer end is engaged with the tooth groove.

[0018] Further, the driving plate is hinged to the fixing plate, and an elastic pad is arranged between one end of the fixing plate away from the driving shaft and the driving plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the present invention, two push rods are arranged on the fixing seat for placing the scraper, which are respectively arranged in parallel on both sides of the scraper. Before the visual detection component works, while the two push rods move downward towards the upper end of the scraper, they can contact the surface of the push rods and lift the burrs attached to the surface, so that it can be clearly judged whether there are burrs in the image obtained by the visual detection component;

[0021] When the visual detection component starts to take an image, the fixing pin can be inserted into the fixing hole of the scraper for locking, so as to prevent the scraper from being displaced by the acting force of the push rod;

[0022] The degree of automation of the whole quality detection process is relatively high. Only by placing the scraper on the fixing seat can the quality detection be completed. At the same time, the accuracy is very high, avoiding the phenomenon of missed judgment due to the attachment of burrs. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal connection of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0036] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but are in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature.

[0037] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] Embodiment:

[0039] In life, scrapers are mostly divided into two types. One is a full-metal product, and the other has a scraper blade made of carbon fiber or other fiber materials. No matter which material it is, there will be burrs during processing due to the process or material. Some of these burrs will be eliminated during polishing or grinding, while some burrs attached to the blade surface are difficult to remove.

[0040] In the existing technology, a vision camera is mostly used to take pictures of the edge of the scraper. By comparing whether there are many situations such as missing parts or uneven thickness in the image of the scraper edge, because the burrs are small in volume and there is a certain allowable error value for the straightness of the scraper blade surface, it is easy to misjudge during the image judgment process, that is, the burrs are regarded as just a change in the blade surface thickness within the allowable range. And the burrs will turn up during subsequent use and swing on the carrier as the scraper moves, affecting the printing effect.

[0041] Please refer to Figures 1 - 10 , a scraper quality detection device proposed in this solution can push the burrs on both sides of the blade surface to bulge during the process of taking a vision picture of the scraper, which can increase the thickness at the position where the burrs are located, facilitating the intuitive detection of defects in the image.

[0042] Specifically, a scraper fixing component 2 and a vision detection component 3 are arranged on the frame 1 in this case. The scraper fixing component 2 includes a fixing seat 21 installed at the upper end of the frame 1. First, place the working end of the scraper upward (the scraper is normally rectangular, and the two side edges at one end of the scraper are the actual working parts, that is, the edge) on the fixing seat 21. There is a placement groove 211 for placing the scraper at the upper end of the fixing seat 21. The notch of the placement groove 211 is vertically upward and the included angle between the two inner ends in the groove is 90 degrees. Thus, the placed scraper will be inclined at 45 degrees with respect to the upper end surface of the frame 1. In the existing technology, most are placed horizontally or vertically, which will cause the external light source to affect the normal lighting of the vision detection component 3 and affect the shooting effect. And in order to further reduce the influence of the external light source on the shooting light source, a light-shielding cover 6 is arranged above the scraper to block the place where the external light shines on the scraper.

[0043] In this case, the light source is directly opposite to the upper end of the blade, covering the entire plane of the upper end of the blade. Different from the prior art, the visual detection assembly 3 includes a first detection camera 31 and a second detection camera 32 movably mounted on the frame 1. The first detection camera 31 and the second detection camera 32 can reciprocate along one side direction of the frame 1, and the lenses of the first detection camera 31 and the second detection camera 32 face the two side edges of the upper end of the blade. In this way, even when the first detection camera 31 and the second detection camera 32 are moving, the light source can still provide good supplementary lighting for the blade.

[0044] Since the blade is inclined, the lenses of the first detection camera 31 and the second detection camera 32 in this case will also align with the two side edges of the upper end of the blade at an angle. Specifically, the lens of the first detection camera 31 is vertically downward, directly opposite to a side edge of the blade facing the visual detection assembly 3, and the lens of the second detection camera 32 faces the other side edge of the blade.

[0045] It should be noted that the first detection camera 31 and the second detection camera 32 in this case will be on one side of the blade before moving. When starting to move, they will move synchronously along the length direction of the blade, take pictures of the side edges of the blade and compare them in real time. The driving methods of the first detection camera 31 and the second detection camera 32 in this case are not specifically limited, and an alarm structure is provided on the frame 1. When the pictures taken by the first detection camera 31 and the second detection camera 32 have defects, an alarm will be triggered, indicating that the quality of this part of the blade is unqualified.

[0046] In this case, when detecting some metal blades or blades of other materials that are prone to burrs, before the first detection camera 31 and the second detection camera 32 perform the shooting work, the surfaces on both sides of the upper end of the blade need to be scraped once in the direction of the upper end of the blade. If there are burrs, they will arch or flip in the direction of the upper end of the blade under the action of the thrust. After the captured image is binarized, a "black dot" with a relatively large area will be formed, which helps to distinguish and identify defective products.

[0047] Specifically, in this case, two brackets 212 that can move along the width direction of the blade are provided on the fixed seat 21. The two brackets 212 are respectively located at the two side ends of the blade. Two push rods 213 are movably installed between the two brackets 212. The two push rods 213 are symmetrically distributed with the blade as the center. When the visual detection assembly 3 starts to work, the two push rods 213 move towards the blade at the same time and fit on the side end faces of the blade, pushing the burrs on the blade to the two side edges of the upper end of the blade.

[0048] The cross-section of the push rod 213 is a right triangle. One end is parallel to the blade surface of the scraper, and the inclined surface faces away from the blade surface of the scraper. While the push rod 213 moves in the direction towards the upper end of the scraper, the distance between the two push rods 213 will decrease, and the force on the surface of the scraper will gradually increase. The relatively sharp end will contact the burrs on the blade surface of the scraper and arch or flip the burrs as it continues to move.

[0049] In this case, on both sides of the fixed seat 21, there is an inclined sliding arm 214 respectively. The sliding arm 214 is arranged at an angle of 45 degrees with the fixed seat 21. The two brackets 212 are respectively installed on the two sliding arms 214 in a guiding manner and reciprocate along the inclined direction of the sliding arm 214. A chute is provided along the direction of the sliding arm 214, and the bracket 212 slides in the chute through a slide rail.

[0050] There are not too many restrictions on the way to drive the brackets 212 to move simultaneously. It can be driven by a motor, a motor, etc. In this case, a relatively economical driving method is proposed.

[0051] Two driving arms 4 are elastically hinged on the fixed seat 21. One side of the two driving arms 4 always abuts against the bottom ends of the two brackets 212 respectively. The two driving arms 4 are both sleeved on a driving shaft 41. The driving shaft 41 is arranged parallel to the scraper and starts to rotate when the first detection camera 31 and the second detection camera 32 move along one side direction of the frame 1.

[0052] During the process of the driving arms 4 starting to rotate, they will continuously "lift" the two brackets 212 upwards. The two driving arms 4 are both sleeved on a driving shaft 41 and rotate synchronously through the rotation of the driving shaft 41. In this case, a track is arranged along the length direction of the fixed seat 21, and a roller 7 is arranged in the track. The roller 7 in this case moves synchronously with the first detection camera 31 and the second detection camera 32. And the roller 7 is closer to the fixed seat 21 at the initial position compared with the first detection camera 31 and the second detection camera 32. That is, before the first detection camera 31 and the second detection camera 32 start to work, the roller 7 has already started to roll, and the moving speed is greater than the moving speed of the first detection camera 31 and the second detection camera 32, and the driving shaft 41 is rotated by rolling. After reaching the maximum rotation angle, the first detection camera 31 and the second detection camera 32 move to take pictures. That is, before taking pictures, the driving arms 4 have already rotated a certain angle to make the brackets 212 rise and reach the maximum angle.

[0053] In this case, a path plate 411 is installed in the middle of the drive shaft 41. The path plate 411 is located on the moving path of the roller 7. When the roller 7 rolls over the path plate 411, the path plate 411 will be flipped, that is, the drive shaft 41 will rotate. When the roller 7 is completely on the path plate 411, the drive shaft 41 reaches the maximum rotation angle. At this time, the push rod 213 has completed the work of pushing the surface of the scraper. The driving method of the roller 7 is not specifically limited and can use an independent driving unit, such as a motor, a motor or an electric rod, etc.

[0054] It should be noted that the moving speeds of the first detection camera 31 and the second detection camera 32 are faster than the moving speed of the roller 7. Since the length of the path plate 411 is less than that of the scraper, when the roller 7 rolls on the path plate 411, although it approaches the fixed seat 21 earlier than the first detection camera 31 and the second detection camera 32, the first detection camera 31 and the second detection camera 32 can still catch up with the roller 7 and reach the other side of the path plate 411 earlier than the roller 7, until taking pictures of the side edges of the entire scraper. When the roller 7 disengages from the path plate 411, since the two driving arms 4 in this case are elastically rotated through the drive shaft 41, a torsion spring is arranged between the drive shaft 41 and the fixed seat 21. When the drive shaft 41 is forced to flip with the path plate 411, a certain amount of elastic potential energy will be accumulated. When the path plate 411 is no longer rolled by the roller 7, under the action of the elastic force, the driving arm 4 is reset, so that under the action of gravity, the bracket 212 slides downward again and moves away from the upper end of the scraper.

[0055] During the rising process of the bracket 212 in this case, the two push rods 213 fixed between the two brackets 212 will move simultaneously in the direction of the scraper side. When the bracket 212 descends, that is, slides along the direction of the sliding arm 214, the distance between the two push rods 213 will increase.

[0056] Specifically, a lever 215 is vertically connected to the side end of each push rod 213. The two levers 215 are symmetrically distributed with the sliding arm 214 as the center, and each lever 215 always fits on the side end face of the sliding arm 214. At the same time, an elastic member is arranged between the side of the push rod 213 away from the sliding arm 214 and the fixed seat 21. The elastic member in this case is the return spring 216.

[0057] And on the side end face of the sliding arm 214, an expansion part 2141 and a downward sliding part 2142 are successively arranged from bottom to top. The downward sliding part 2142 is connected above the expansion part 2141, and the distance between the two downward sliding parts 2142 on both sides of the sliding arm 214 is less than the distance between the two expansion parts 2141 on both sides.

[0058] When the lever 215 on the push rod 213 fits against the expansion part 2141, the two levers 215 will be "spread apart". At this time, the return spring 216 is in a compressed state, so the distance between the two push rods 213 will be relatively large. At this time, the scraper is placed in the space between the two push rods 213 and placed in the placement groove 211. When the lever 215 on the push rod 213 moves downward along the expansion part 2141 towards the sliding part 2142, the elastic force of the return spring 216 is released, and the distance between the two levers 215 will become smaller, and then it is expected to touch the scraper. And this action is completed before the drive shaft 41 reaches the maximum rotation angle. When the maximum rotation angle is reached, the lever 215 will be completely in the sliding part 2142.

[0059] It should be noted that in this case, the force for the push rod 213 to return to the initial state, that is, to make the lever 215 return to the expansion part 2141 again, is the gravity of the push rod 213 and the bracket 212 itself. When the push rod 213 reaches the maximum moving stroke (towards the upper end of the scraper), the force on the scraper is not particularly large, and the gravity of the bracket 212 and the push rod 213 itself is greater than the elastic force of the return spring 216, so the situation where the lever 215 cannot contact the expansion part 2141 will not occur. The specific reset method can be various and will not be overly limited.

[0060] And in this case, there are at least two sliding parts 2142, and when approaching the upper end of the scraper, the distance between the two sliding parts 2142 on both sides gradually becomes smaller. Different numbers of sliding parts 2142 can be set to provide different spaces formed between the two push rods 213 to adapt to scrapers of different thicknesses. (The length of the driving arm 4 needs to be adjusted. The specific replacement structure is a well-known technology. The longer the driving arm 4, the larger the swing angle and the larger the moving amplitude of the push rod 213. This will not be specifically described here.)

[0061] It should be noted that in this case, in order to prevent the push rod 213 from causing the displacement of the scraper when applying force to the surface of the scraper, an auxiliary fixing structure is also provided.

[0062] Specifically, a fixing plate 5 that can move vertically towards the scraper is provided inside the fixing seat 21. A number of fixing pins 51 are provided on the fixing plate 5. The fixing pins 51 are arranged corresponding to the fixing holes of the scraper and are inserted into the fixing holes of the scraper when the fixing plate 5 approaches the scraper. The fixing holes of the scraper are a common structure for fixing the scraper in printing equipment and are well-known technologies.

[0063] When the scraper is fixed on the placement groove 211, it is only supported by the groove body. If there is an external force, it is easy to cause the scraper to tilt. In this case, especially when a force is applied above the scraper, the scraper will be subjected to an upward pulling force. Thus, when the scraper starts to be stressed, the fixing pin 51 will immediately pop out of the fixing seat 21 together with the fixing plate 5. The fixing pin 51 will be inserted into the fixing hole corresponding to the scraper. Even when stressed, under the limit of the fixing pin 51, it is ensured that the scraper will not easily break away from the fixing seat 21.

[0064] Moreover, according to the different models of the scraper, the positions of its fixing holes will also be different. Thus, in this case, the distance between each fixing pin 51 and the scraper can be adjusted. The fixing pin 51 is in threaded cooperation with the fixing plate 5, and a concave hole for feeding the other side of the fixing pin 51 is provided on the fixing seat 21. When the fixing pin 51 is rotated into the concave hole, even when the fixing plate 5 moves towards the scraper, the fixing pin 51 will not enter the fixing hole of the scraper. A plurality of fixing pins 51 are provided and can be freely matched, and different insertion paths can be selected according to different products.

[0065] In this case, a driving plate 52 is provided on one side of the fixing plate 5. The driving plate 52 is located below the driving shaft 41, and a tooth groove 521 is provided at the upper end of the driving plate 52. The driving shaft 41 is always in contact with the fixing plate 5 and its outer end is engaged with the tooth groove 521. Thus, when the driving shaft 41 starts to rotate, the driving shaft 41 will guide the fixing plate 5 to slide in the fixing seat 21. During the process of moving towards the scraper, when the driving plate 52 is in cooperation with the driving shaft 41, there is a downward force. In this case, the driving plate 52 is hinged to the fixing plate 5, and an elastic pad 53 is provided between the end of the fixing plate 5 far from the driving shaft 41 and the driving plate 52. Thus, the elastic pad 53 will be compressed by a certain stroke to prevent the fixing plate 5 from being difficult or unable to slide normally. When the driving shaft 41 is reset, the driving plate 52 will pull the fixing plate 5 to reset at the same time, and the fixing pin 51 will no longer be fixed in the fixing hole, releasing the locking of the scraper.

[0066] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
