Description

Technical Field

[0001] This utility model belongs to the field of inkjet printing verification technology, and specifically relates to an inkjet printing verification camera motion module. Background Technology

[0002] Inkjet printing verification is a process that uses technical means to inspect and verify the quality of inkjet printing information on the surface of a product, ensuring the accuracy, completeness, and clarity of the printed content, such as production date, batch number, and serial number, and avoiding product quality problems or recall risks caused by inkjet printing errors; its camera module often includes an industrial camera.

[0003] In the current technology, industrial cameras in product coding quality inspection systems are usually fixedly mounted on brackets. Their position, angle, and focal length are preset or fixed with bolts and nuts, making it difficult to adjust in real time. For products with curved or obviously uneven surfaces, such as bottles, cans, and irregularly shaped packaging, this rigid mounting method makes it difficult for cameras with fixed viewing angles and focal planes to achieve uniform and clear focus throughout the entire imaging area. This can easily lead to blurred images in edge areas, decoding failures, or misjudgments, affecting the accuracy and reliability of the verification.

[0004] Secondly, due to the complex and variable ambient light in industrial environments, and the fact that product surface materials, such as reflective film, metal caps, and dark-colored bottles, are prone to specular reflection or local overexposure, stationary cameras cannot effectively avoid areas of strong light interference. Relying solely on software algorithms for exposure compensation has limited effectiveness, especially on high-speed production lines, where it is difficult to stably obtain high-contrast inkjet printing images, resulting in a high rate of missed detections.

[0005] Furthermore, in the face of the trend of multi-variety, small-batch production, production lines need to frequently switch between different product specifications. However, existing fixed camera systems often require manual readjustment of camera position, angle and focal length each time a product is changed, and even replacement of brackets. This not only makes debugging time-consuming and laborious, prolonging downtime, but also easily introduces human error, reducing the flexibility and efficiency of the production line, making it difficult to meet the rapid response requirements of modern intelligent manufacturing. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coding verification camera motion module.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a coding verification camera motion module, comprising a coding body and a camera module. The coding body includes a vertical motion module and an angle deflection module. The angle deflection module includes a base plate. L-shaped arc members are fixed on both sides of the bottom of the base plate. Multiple bearing seats are fixed on the inner wall of the base plate. A meshing rod is rotatably connected to the inner wall of the bearing seats. The meshing rod is driven by a main motor. An inverted L-shaped member is slidably connected to the surface of the L-shaped arc member. A moving member is fixed to the bottom of the inverted L-shaped member. An arc tooth member is fixed to the inner wall of the moving member. The tooth groove of the arc tooth member meshes with the surface of the meshing rod. A camera module is fixed to the bottom of the moving member.

[0008] Preferably, the inverted L-shaped part has a moving groove in the middle, and the L-shaped arc part has a limiting block fixed in the middle.

[0009] Preferably, indicator lights are fixed at corresponding locations on the side of the substrate and the side of the moving part.

[0010] Preferably, the vertical motion module includes a vertical screw and multiple pulleys. A pulley is fixed to the top of the vertical screw, and a transmission belt is provided on the surface of the pulley. Another pulley is driven by an auxiliary motor. A drive fixing member is engaged on the surface of the vertical screw, and the surface of the drive fixing member is fixed to the angle deflection module.

[0011] Preferably, the drive fixing member has a groove on its peripheral surface, the inner wall of the groove is fixed to the side of the substrate, and an abutting protrusion is provided below the groove of the drive fixing member, the top of the abutting protrusion being in contact with the bottom of the substrate.

[0012] Preferably, a limiting plate is fixed to the top of the drive fixing component, the inner wall of the limiting plate is threadedly connected to the surface of the vertical screw, the top of the limiting plate is fixed to the top of the base plate by bolts, and the back of the limiting plate is attached to the surface of the vertical motion module.

[0013] Preferably, the vertical motion module includes multiple track components, and a slider is slidably connected to the surface of each track component, with the surface of the slider fixed to the back of the substrate.

[0014] Preferably, an auxiliary fixing plate is fixed to the surface of the slider, and the auxiliary fixing plate is fixed to the top of the base plate by bolts.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model utilizes the main motor of the angle deflection module to drive the meshing rod, causing the arc-shaped component to rotate. This, in turn, causes the moving component to move in an arc shape under the meshing and following action of the arc-shaped component and the sliding cooperation between the inverted L-shaped component and the L-shaped arc component. This leads the camera module to move in an arc shape towards the product at the inkjet printing location, thus enabling better image acquisition and verification of products with curved or significantly uneven surfaces. It facilitates uniform and clear focusing of the camera module throughout the imaging area, improving the accuracy and reliability of verification. Furthermore, in industrial environments with complex and variable ambient light, operators can easily adjust the camera module's shooting angle by simply controlling the rotation of the main motor, effectively avoiding areas of strong light interference and thus stably acquiring high-contrast inkjet printing images, improving the yield rate.

[0017] 2. This utility model, by setting a vertical motion module, allows for rapid adjustment of the camera module's height via a vertical screw, facilitating the switching of production lines according to different product specifications. This improves the applicability and enhances the flexibility and efficiency of the production line. Furthermore, the vertical screw's height is adjusted via a power transmission from an auxiliary motor to multiple pulleys and a conveyor belt. This method lowers the auxiliary motor's height, preventing accidental contact and damage, and keeps it further away from the work area, preventing accidental injury from workers placing objects or body parts there. Additionally, this method ensures that the auxiliary motor and vertical screw do not come into contact when needed for maintenance or replacement, preventing disassembly of the entire unit due to damage to a single part and minimizing the impact of disassembly on another component, thus improving equipment stability.

[0018] 3. This utility model limits the movement distance of the moving part by cooperating with the moving groove and the limiting block. This prevents the moving part from moving too far along the arc due to accidental operation of the sensor, main motor or manual operation, which would cause the meshing rod to rotate too many times, resulting in abnormal wear of the meshing rod and the arc tooth or the moving part falling off the base plate. The cooperation of the two limits the movement distance, improves the stability of the equipment and prevents secondary damage caused by abnormal wear or falling off.

[0019] 4. This utility model restricts the vertical movement module by attaching a limiting plate to the surface of the vertical movement module. When the vertical screw rotates, the limiting plate acts as a constraint through this contact method, eliminating the need for additional limiting plates or grooves. This facilitates disassembly and assembly while reducing the complexity of parts use and processing. The groove of the drive fixing component brings the base plate closer to the surface of the vertical movement module, preventing breakage at the fixing point due to excessive lever arm. Furthermore, the contact protrusion contacts the base plate and provides support, preventing damage caused by the base plate's tendency to tilt outwards, thus improving its service life.

[0037] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0038] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0039] Example 1:

[0040] refer to Figures 1-7 The inkjet printing verification camera motion module includes an inkjet printing body 1 and a camera module 204. The inkjet printing body 1 includes an axial motion module, a parallel motion module, a vertical motion module, and an angle deflection module. The angle deflection module includes a base plate 2. L-shaped arc members 201 are fixed on both sides of the bottom of the base plate 2. Multiple bearing seats 206 are fixed on the inner wall of the base plate 2. A meshing rod 207 is rotatably connected to the inner wall of the bearing seat 206. The meshing rod 207 is driven by a main motor 208. An inverted L-shaped member 202 is slidably connected to the surface of the L-shaped arc member 201. A moving member 203 is fixed to the bottom of the inverted L-shaped member 202. An arc tooth member 205 is fixed to the inner wall of the moving member 203. The tooth groove of the arc tooth member 205 meshes with the surface of the meshing rod 207. The camera module 204 is fixed to the bottom of the moving member 203.

[0041] Specifically, the main motor 208 of the angle deflection module drives the meshing rod 207 to rotate the arc-shaped component 205. This causes the moving component 203 to move in an arc shape under the meshing and following of the arc-shaped component 205 and the sliding cooperation between the inverted L-shaped component 202 and the L-shaped arc component 201. This leads the camera module 204 to move in an arc shape toward the product on the inkjet printer body 1, with the center of the arc-shaped component 205 as the axis. This allows for better image acquisition and verification of products with curved or obviously uneven surfaces. It also facilitates uniform and clear focusing of the camera module 204 throughout the imaging area, improving the accuracy and reliability of verification. Furthermore, in industrial environments with complex and variable ambient light, operators can easily adjust the shooting angle of the camera module 204 by controlling the rotation of the main motor 208, effectively avoiding areas of strong light interference, thereby stably acquiring high-contrast inkjet images and improving the yield rate.

[0042] The inverted L-shaped part 202 has a moving groove 3 in the middle, and the L-shaped arc part 201 has a limiting block 301 fixed in the middle. Indicator lights 4 are fixed at corresponding positions on the side of the base plate 2 and the side of the moving part 203.

[0043] Specifically, the movement distance of the moving part 203 is limited by the cooperation of the moving groove 3 and the limiting block 301. This prevents the moving part 203 from moving too far along the arc due to excessive rotation of the meshing rod 207 caused by the sensor, main motor 208, or manual operation, which could lead to abnormal wear of the meshing rod 207 and the arc tooth 205 or the moving part 203 falling off the base plate 2. The cooperation of the two limits the movement of the moving part 203, improves the stability of the equipment, and prevents secondary damage caused by abnormal wear or falling off the base plate 2. In addition, the indicator light 4 allows the operator to quickly judge the rotation angle, improving the user experience.

[0044] The vertical motion module includes a vertical screw 5 and multiple pulleys 502. A pulley 502 is fixed to the top of the vertical screw 5. A transmission belt 501 is provided on the surface of the pulley 502. Another pulley 502 is driven by an auxiliary motor 503. A drive fixing member 504 is engaged on the surface of the vertical screw 5. The surface of the drive fixing member 504 is fixed to the angle deflection module.

[0045] Specifically, by setting up a vertical motion module, the height of the camera module 204 can be quickly adjusted via the vertical screw 5, making it easier for staff to switch production lines according to different product specifications, thereby increasing the applicability and improving the flexibility and efficiency of the production line. Furthermore, the height of the vertical screw 5 is adjusted via power transmission from the auxiliary motor 503 to multiple pulleys 502 and the transmission belt 501. This method lowers the height of the auxiliary motor 503, rather than fixing it directly to the vertical screw 5, preventing accidental contact and damage. It also keeps the auxiliary motor 503 further away from the work area, preventing accidental injury caused by staff placing debris or body parts in the work area. Additionally, this method ensures that the auxiliary motor 503 or the vertical screw 5 does not come into contact with each other when they need maintenance or replacement, preventing the need for complete disassembly due to damage to a single part and preventing the impact of disassembly on another part, thus improving equipment stability.

[0046] The drive fixing component 504 has a groove 6 on its circumferential surface. The inner wall of the groove 6 is fixed to the side of the substrate 2. An abutment protrusion 601 is provided below the groove 6 of the drive fixing component 504. The top of the abutment protrusion 601 is attached to the bottom of the substrate 2. A limiting plate 7 is fixed to the top of the drive fixing component 504. The inner wall of the limiting plate 7 is threaded to the surface of the vertical screw 5. The top of the limiting plate 7 is fixed to the top of the substrate 2 by bolts. The back of the limiting plate 7 is attached to the surface of the vertical motion module.

[0047] Specifically, the limiting plate 7 is attached to the surface of the vertical motion module for restriction. When the vertical screw 5 rotates, the limiting plate 7 acts as a restriction through this contact method, eliminating the need for additional limiting modules or slots. This facilitates disassembly and assembly while reducing the complexity of parts use and processing. The groove 6 of the drive fixing member 504 brings the base plate 2 closer to the surface of the vertical motion module, preventing breakage at the fixing point due to excessive lever arm. Furthermore, the contact protrusion 601 contacts the base plate 2 and provides support, preventing damage caused by the base plate 2 tilting outward and improving its service life.

[0048] The vertical motion module includes multiple track components 8, with sliders 801 slidably connected to the surface of each track component 8. The surface of sliders 801 is fixed to the back of the base plate 2. An auxiliary fixing plate 9 is fixed to the surface of sliders 801 and is fixed to the top of the base plate 2 by bolts.

[0049] Specifically, multiple track components 8 and sliders 801 ensure that the base plate 2 maintains a stable vertical movement, preventing the end of the vertical screw 5 from wobbling when it is long, which could cause offset and abnormal wear. At the same time, the auxiliary fixing plate 9 further improves the fixing effect with the base plate 2 and enhances the stability of the equipment.

[0050] Example 2:

[0051] refer to Figures 1-7 The staff used the structure disclosed in this utility model on the bottling production line of a well-known beverage company.

[0052] This invention utilizes the inkjet printing verification camera motion module. The production line processes 36,000 250ml aluminum alloy beverage cans per hour, with the inkjet printing including production date, batch number, and QR code information. The verification system, installed at the end of the production line, uses a KISSH YV series industrial camera as the camera module. A main motor drives a meshing rod that engages with an arc-shaped component, allowing the camera to move along an arc-shaped trajectory with a radius of 280mm, covering a 0-30 degree tilt range on the top of the can. When a can with strong reflectivity is detected, the system automatically controls the main motor to rotate, causing the camera to deflect 12 degrees to avoid the glare area. The vertical motion module uses a Delta 750W servo motor to drive a pulley assembly, which in turn drives a vertical screw to achieve precise lifting and lowering of the camera within a range of 650-950mm from the conveyor belt. Actual operation data shows that this module increases the inkjet printing recognition rate from 92.3% with a fixed camera solution to 99.7%, and reduces the camera adjustment time for each product specification change from 15 minutes manually to less than 25 seconds automatically adjusted by the system. The cooperation between the track components and the slider ensures that the camera maintains a positional deviation of less than 0.05 mm under high-speed vibration environment, and the indicator lights display the angle and height status in real time, effectively ensuring that the production line can run continuously for 18 hours without failure.

[0053] The working principle of this utility model is as follows: When the staff needs to adjust the position or angle of the camera module 204, the main motor 208 drives the meshing rod 207 to rotate in the bearing seat 206. The meshing rod 207 meshes with the arc tooth 205 in the moving part 203, which drives the moving part 203 to move.

[0054] The moving part 203 is slidably connected to the L-shaped arc parts 201 on both sides of the bottom of the substrate 2 via the inverted L-shaped part 202, so that the moving part 203 moves along the arc trajectory, thereby driving the camera module 204 at its bottom to move in an arc with the product facing the inkjet body 1 as the center, so as to achieve adaptive focusing on the surface of the arc or concave and convex product; the moving groove 3 of the inverted L-shaped part 202 and the limiting block 301 of the L-shaped arc part 201 cooperate to limit the movement stroke and prevent excessive wear;

[0055] Furthermore, the auxiliary motor 503 of the vertical motion module drives the vertical screw 5 to rotate through the pulley 502 and the transmission belt 501, causing the drive fixing member 504, which meshes with the vertical screw 5, to lift the entire substrate 2. The groove 6 of the drive fixing member 504 is fixed to the side of the substrate 2, and the abutting protrusion 601 below it supports the bottom of the substrate 2. The limiting plate 7 is attached to the surface of the vertical motion module, which not only plays a limiting role but also enhances stability. The sliding connection between the track member 8 and the slider 801 ensures that the vertical movement of the substrate 2 is without deviation. The indicator light 4 on the side of the substrate 2 and the moving member 203 displays the position status in real time, thereby realizing the precise linkage adjustment of the height and angle of the camera module 204, adapting to different product specifications and ambient light, and improving the clarity and accuracy of inkjet printing verification.

[0056] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
