Description

Technical Field

[0001] This utility model application relates to the field of surface panel flatness detection technology, specifically to a visual inspection-based device for detecting the flatness of mixed-oil surface panel doors. Background Technology

[0002] In the wooden door manufacturing and home customization industry, painted finish door panels are widely used in modern home decoration due to their opaque paint surface, which completely conceals the wood grain and presents rich colors. The surface flatness of these door panels directly affects the product's aesthetics, sealing performance, and lifespan. Traditional methods for testing the flatness of painted finish door panels have many drawbacks. Some companies use manual touch or visual inspection, which heavily relies on worker experience and subjective judgment. Workers are prone to fatigue from prolonged work, leading to decreased inspection accuracy and making it difficult to guarantee the accuracy and consistency of results. Furthermore, manual inspection is inefficient, unable to meet the testing needs of large-scale production, and increases labor costs for companies. With the development of technology, machine vision technology is gradually being applied to the industrial inspection field. Machine vision technology has advantages such as non-contact operation, high precision, high speed, and high automation, providing a new solution for testing the flatness of painted finish door panels.

[0003] Existing equipment generally suffers from insufficient positioning accuracy in the door panel conveying process. Decorative door panels are prone to shifting during transport, causing the vision inspection system to fail to accurately capture key feature points on the door panel surface, thus affecting the accuracy of flatness detection. Furthermore, some equipment uses a combination of conveyor belts and pressure rollers, which, while ensuring stable door panel transport to some extent, results in extensive contact between the conveyor belt and the door panel surface, easily scratching the paint and causing irreversible damage, severely impacting product quality. Utility Model Content

[0004] The purpose of this utility model application is to provide a visual inspection-based device for detecting the flatness of mixed-oil finish door panels. It employs a method of coordinating upper and lower synchronous belts to transport the finish door panels. Compared to traditional conveying methods, this significantly reduces the contact area between the synchronous belts and the door panel surface, effectively minimizing scratches, wear, and other damage to the paint surface caused by contact friction, thus maximizing the product's appearance quality. Limiting wheels further restrict the movement of the finish door panels during transport, ensuring that the panels maintain a stable and correct position throughout the entire transmission process.

[0005] To address the problems in the prior art, this utility model application provides a visual inspection-based device for detecting the flatness of mixed-oil finish door panels, comprising: a body; two sets of conveying components, each set being disposed on one side of the top of the body; and a detection component disposed at the center of the top of the body and installed at the junction of the two conveying components for detecting the flatness of the finish door panel. The conveying components include two symmetrical support plates that can synchronously move closer or further apart. First synchronous wheels are rotatably mounted at both ends of the support plates, and a first synchronous belt is fitted between the first synchronous wheels. A lifting plate capable of vertical movement is also provided on the top of the support plates, and second synchronous wheels are rotatably mounted at both ends of the lifting plate, with a second synchronous belt fitted onto the second synchronous wheels.

[0006] Preferably, the inner side of the support plate is vertically rotatably provided with a plurality of limiting wheels that can constrain the decorative door panel to the center position of the conveying assembly.

[0007] Preferably, a sleeve is vertically provided on the outside of the support plate, and a guide rod is provided on the lifting plate, and the guide rod can be inserted into the sleeve and slide in the sleeve.

[0008] Preferably, a telescopic drive component capable of driving the lifting plate to move up and down is vertically mounted on the outer side of the support plate, and the output end of the telescopic drive component is connected to the lifting plate.

[0009] Preferably, the outer side of the support plate is further provided with a first rotary drive for driving the first synchronous wheel to rotate, and the output end of the first rotary drive is connected to one of the first synchronous wheels.

[0010] Preferably, the outer side of the lifting plate is further provided with a second rotary drive for driving the second synchronous wheel to rotate, and the output end of the second rotary drive is connected to one of the second synchronous wheels.

[0011] Preferably, the conveying assembly further includes a synchronous drive mechanism disposed on the top of the machine body for driving the two support plates to move. The synchronous drive mechanism includes a lead screw rotatably disposed along the width direction of the machine body, and the lead screw is threadedly connected to the support plate. The synchronous drive mechanism also includes a third rotary drive component fixed on the machine body, and the output end of the third rotary drive component is connected to the lead screw. The synchronous drive mechanism includes a slide rail disposed along the width direction of the machine body, and a slider cooperating with the slide rail is disposed at the bottom of the support plate.

[0012] Preferably, the detection component includes a first moving mechanism fixed to the top of the machine body, and a second moving mechanism is also provided on the first moving mechanism, and a detector that can move up and down is provided on the second moving mechanism. The detector is also provided with a visual inspection camera that can be used to detect the flatness of the decorative door panel.

[0013] The advantages of this utility model application compared to the prior art are as follows: This application sets up a support plate and a lifting plate as the core load-bearing components for door panel conveying. A first synchronous wheel is rotatably mounted on the support plate, and a first synchronous belt is fitted onto the first synchronous wheel. Similarly, a second synchronous wheel is rotatably mounted on the lifting plate, and a second synchronous belt is fitted onto the second synchronous wheel. By controlling the lifting movement of the lifting plate, the first and second synchronous belts can clamp the decorative door panel with appropriate pressure. This clamping method significantly reduces the contact area between the synchronous belt and the door panel surface. Compared to traditional large-area contact conveying methods, it greatly reduces scratches, wear, and other damage to the paint surface of the mixed-oil decorative door panel caused by contact friction, effectively ensuring the appearance quality of the product. Furthermore, to ensure the stability and positioning accuracy of the decorative door panel during conveying, this application sets up a limiting wheel. During door panel conveying, the limiting wheel contacts the edge of the door panel, and through its guiding function, it ensures that the decorative door panel maintains a stable and correct position throughout the entire conveying process, effectively avoiding deviations and shaking of the door panel during conveying. This limiting design provides a solid foundation for subsequent detection of the surface flatness of the decorative door panel based on a visual inspection system. Attached Figure Description

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-6 As shown, this utility model application provides a visual inspection-based device for detecting the flatness of mixed-oil decorative door panels, comprising: a body 1; two sets of conveying components 2, which are respectively arranged on both sides of the top of the body 1; and a detection component 3, which is arranged at the center of the top of the body 1 and installed at the junction of the two conveying components 2 for detecting the flatness of the decorative door panels. The conveying components 2 include two symmetrical support plates 21 that can move synchronously closer or further away from each other. The two ends of the support plates 21 are rotatably provided with first synchronous wheels 211, and a first synchronous belt 212 is sleeved between the first synchronous wheels 211. The top of the support plates 21 is also provided with a lifting plate 22 that can move up and down, and the two ends of the lifting plate 22 are rotatably provided with second synchronous wheels 221, and a second synchronous belt 222 is sleeved on the second synchronous wheels 221.

[0023] When flatness testing of a mixed-oil finish door panel is required, the distance between the support plates 21 in the two conveying components 2 is first adjusted according to the size of the door panel to ensure that the support plates 21 can accommodate the width of the door panel. Simultaneously, the height of the lifting plate 22 is adjusted to ensure that the distance between the first synchronous belt 212 and the second synchronous belt 222 is suitable for the thickness of the door panel, ensuring that both can stably clamp the door panel. The mixed-oil finish door panel is then placed in one of the conveying components 2 and activated. At this time, the first synchronous wheel 211 and the second synchronous wheel 221 begin to rotate, driving the first synchronous belt 212 and the second synchronous belt 222 to move. The first synchronous belt 212 and the second synchronous belt 222 clamp the door panel through friction, smoothly conveying the door panel to the detection position of the detection component 3. When the door panel reaches below the detection component 3, the detection component 3 activates the vision inspection system to acquire image information of the door panel surface. The acquired image is analyzed using a preset image processing algorithm. By comparing the relative height of various points on the door panel surface and detecting whether there are unevenness or irregularities on the surface, the flatness of the door panel is determined to meet the requirements. After the test is completed, the conveying component 2 continues to work, conveying the door panel to the other end of the device for delivery.

[0024] The inner side of the support plate 21 is vertically rotatably equipped with several limiting wheels 24 that can constrain the decorative door panel to the center position of the conveying assembly 2. When the door panel enters the conveying assembly 2, the limiting wheels 24 contact the edge of the door panel and guide the door panel to the center position by rotation, so as to avoid the door panel from being deviated during the conveying process and affecting the accuracy of detection.

[0025] A sleeve 213 is vertically installed on the outside of the support plate 21, and a guide rod 223 is installed on the lifting plate 22. The guide rod 223 can be inserted into the sleeve 213 and slide within the sleeve 213. A telescopic drive component 25 capable of driving the lifting plate 22 to move up and down is vertically installed on the outside of the support plate 21, and the output end of the telescopic drive component 25 is connected to the lifting plate 22.

[0026] The telescopic drive component 25 provides power to drive the lifting plate 22 to move up and down. By controlling the telescopic length of the drive component 25, the height of the lifting plate 22 can be adjusted, thereby controlling the distance between the second synchronous belt 222 and the first synchronous belt 212 to meet the clamping requirements of door panels of different thicknesses. The telescopic drive component 25 can be a common telescopic drive device such as a cylinder or an electric push rod.

[0027] The outer side of the support plate 21 is also provided with a first rotary drive member 214 for driving the first synchronous pulley 211 to rotate, and the output end of the first rotary drive member 214 is connected to one of the first synchronous pulleys 211. The outer side of the lifting plate 22 is also provided with a second rotary drive member 224 for driving the second synchronous pulley 221 to rotate, and the output end of the second rotary drive member 224 is connected to one of the second synchronous pulleys 221.

[0028] When the first rotary drive 214 is started, it drives the first synchronous pulley 211 connected to it to rotate through the transmission at the output end. Then, it drives the other first synchronous pulley 211 to rotate synchronously through the first synchronous belt 212, so that the first synchronous belt 212 moves. When the second rotary drive 224 is started, it drives the second synchronous pulley 221 connected to it to rotate through the transmission at the output end. Then, it drives the other second synchronous pulley 221 to rotate synchronously through the second synchronous belt 222, so that the second synchronous belt 222 moves.

[0029] The transmission assembly 2 also includes a synchronous drive mechanism 23 disposed on the top of the body 1 and used to drive the two support plates 21 to move. The synchronous drive mechanism 23 includes a lead screw 232 rotatably disposed along the width direction of the body 1, and the lead screw 232 is threadedly connected to the support plate 21. The synchronous drive mechanism 23 also includes a third rotary drive component 231 fixed on the body 1, and the output end of the third rotary drive component 231 is connected to the lead screw 232. The synchronous drive mechanism 23 includes a slide rail 233 disposed along the width direction of the body 1, and a slider 215 cooperating with the slide rail 233 is disposed at the bottom of the support plate 21.

[0030] The third rotary drive component 231 in the synchronous drive mechanism 23 is activated. The third rotary drive component 231 drives the lead screw 232 to rotate. Since the lead screw 232 is connected to the support plate 21 by a thread, and the slider 215 at the bottom of the support plate 21 cooperates with the slide rail 233 set along the width direction of the machine body 1, under the rotation of the lead screw 232, the two support plates 21 move closer or further away from each other synchronously along the slide rail 233, thereby adjusting the distance between the two support plates 21 to adapt to the width of the door panel.

[0031] The detection component 3 includes a first moving mechanism 31 fixed to the top of the body 1, and a second moving mechanism 32 is also provided on the first moving mechanism 31. The second moving mechanism 32 is provided with a detector 33 that can move up and down. The detector 33 is also provided with a visual inspection camera 331 that can be used to detect the flatness of the decorative door panel.

[0032] The movement of the first moving mechanism 31 drives the second moving mechanism 32 and the detector 33 mounted on the second moving mechanism 32 to adjust their positions on the body 1. The second moving mechanism 32 causes the detector 33 to move up and down. The visual inspection camera 331 is the core component of the detector 33, specifically used to detect the flatness of the decorative door panel. It collects image information of the door panel surface and converts the actual condition of the door panel surface into digital image signals. Then, it uses a preset image processing algorithm to analyze and process these image signals, such as by comparing the relative height of various points on the door panel surface and detecting whether there are unevenness or other irregularities on the surface, thereby determining whether the flatness of the door panel meets the requirements. The visual inspection camera 331 has the characteristics of high resolution and high precision, and can accurately capture subtle changes in the door panel surface, providing reliable data support for the accurate detection of door panel flatness.

[0033] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
