Description

Technical Field

[0002] In industries such as elevators, furniture, and building decoration, door panels are core components, and their production often adopts a large-scale production model. The dimensional accuracy, especially the width and length, directly determines the adaptability of subsequent assembly and the overall quality of the product. If the door panel dimensions deviate too much, it will lead to problems such as installation difficulties, excessive gaps, and insufficient structural stability, and may even cause safety hazards. On the other hand, relying on manual inspection to control quality is not only inefficient and difficult to match the pace of automated production lines, but also prone to missed or false inspections due to human error, while significantly increasing labor costs.

[0003] With the development of industrial automation technology, door panel production lines are gradually transforming towards full-process automation. However, existing door panel size inspection solutions still have many shortcomings: some inspection devices use manual-assisted positioning, resulting in poor positioning accuracy and low reliability of inspection data; some automated inspection equipment relies on complex high-end technologies such as laser ranging and visual recognition, which have high equipment investment costs and are difficult to maintain, making them unsuitable for the actual needs of small and medium-sized production enterprises; and some inspection devices have poor linkage between positioning and inspection mechanisms, lack stable benchmark positioning structures and precise displacement detection components, making them susceptible to factors such as door panel displacement and mechanism vibration during the inspection process, thus making it difficult to guarantee inspection accuracy.

[0004] Therefore, an automatic door panel detection device is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] An automatic door panel detection device includes a conveyor frame 1, a conveyor belt 2 installed inside the conveyor frame 1, and support frames 3 fixedly welded to the front and rear sides of the top of the conveyor frame 1. A width detection component 4 is provided on the top of the front support frame 3, and a length detection component 5 is provided on the top of the rear support frame 3. The width detection component 4 includes multiple first U-shaped frames 401. A first cylinder 402 is fixedly installed on the right side of the first U-shaped frame 401, and the telescopic end of the first cylinder 402 passes through the first U-shaped frame 401 and is movably connected to it. A transverse reference plate 403 is fixedly connected to the telescopic end of the first cylinder 402. A first servo motor 404 is fixedly installed on the left side of the first U-shaped frame 401, and a first stud 405 is fixedly connected to the output shaft of the first servo motor 404. A transverse positioning plate 406 is threadedly connected to the surface of the first stud 405, and a first displacement sensor 407 is fixedly installed on the side of the transverse positioning plate 406 near the transverse reference plate 403. The first displacement sensor 407 is used in conjunction with the reference plate.

[0029] In this embodiment: by setting the width detection component 4, the first U-shaped frame 401 can provide stable installation support for components such as the first cylinder 402, the first servo motor 404, and the first stud 405. Its multi-point distribution allows for detection of the door panel width from different positions, avoiding deviation at a single detection point and improving detection uniformity and reliability. The first cylinder 402 can provide precise driving force, pushing the transverse reference plate 403 to quickly adhere to one side of the door panel, forming a fixed reference surface for width detection and establishing a unified reference starting point for subsequent detection. The transverse reference plate 403 can fit tightly against the door panel, forming the reference boundary for width detection, while also providing a stable mounting carrier for the first displacement sensor 407. The first servo motor 404 can precisely control... The rotational speed and angle are controlled to drive the first stud 405 to rotate quantitatively, achieving millimeter-level precise displacement adjustment of the transverse positioning plate 406. The first stud 405 can convert the rotational motion of the first servo motor 404 into the linear motion of the transverse positioning plate 406, allowing the transverse positioning plate 406 to fit against the other side of the door panel, jointly defining the width detection range with the transverse reference plate 403, and providing a clear measurement endpoint for the first displacement sensor 407. The first displacement sensor 407 can accurately collect the distance data between the transverse reference plate 403 and the transverse positioning plate 406, directly convert it into the door panel width value, and transmit it to the control system in real time, providing the core basis for width qualification judgment and ensuring that the entire width detection process is efficient and accurate.

[0030] Specifically, such as Figure 4 As shown, the length detection component 5 includes a horizontal plate 501, which is fixedly connected to the top of the rear support frame 3, and a second U-shaped frame 502 is fixedly connected to the top of the horizontal plate 501.

[0031] Specifically, such as Figure 4 As shown, a second cylinder 503 is fixedly installed on the front side of the second U-shaped frame 502. The telescopic end of the second cylinder 503 passes through the second U-shaped frame 502 and is movably connected to the second U-shaped frame 502. A longitudinal reference plate 504 is fixedly connected to the telescopic end of the second cylinder 503.

[0032] Specifically, such as Figure 4 As shown, a second servo motor 505 is fixedly connected to the rear side of the second U-shaped frame 502, and a second stud 506 is fixedly connected to the output shaft of the second servo motor 505. The second stud 506 and the second U-shaped frame 502 are rotatably connected through bearings.

[0033] Specifically, such as Figure 4 As shown, a longitudinal positioning plate 507 is threadedly connected to the surface of the second stud 506, and a second displacement sensor 508 is fixedly installed on the side of the longitudinal positioning plate 507 near the longitudinal reference plate 504.

[0034] In this embodiment: by setting the length detection component 5, the horizontal plate 501 can stably support the second U-shaped frame 502, ensuring the overall stability of the length detection component 5; the second U-shaped frame 502 can provide installation space and a fixed carrier for components such as the second cylinder 503, the second servo motor 505, and the second stud 506; the second cylinder 503 can provide driving force to push the longitudinal reference plate 504 to move quickly and fit against one end of the door panel, forming a fixed reference surface for length detection; the longitudinal reference plate 504 can fit tightly against the end of the door panel, forming the reference boundary for length detection, ensuring the consistency of the reference for each detection, and providing... This lays the foundation for subsequent accurate measurements; the second servo motor 505 can drive the second stud 506 to rotate precisely, thereby realizing the displacement of the longitudinal positioning plate 507. This allows the longitudinal positioning plate 507 to move towards the other end of the door panel and fit tightly under the drive of the second stud 506, thus defining the length detection range together with the longitudinal reference plate 504 and forming the endpoint of the length measurement, providing a clear target for the second sensor detection; the second displacement sensor 508 can accurately collect the distance data between the longitudinal reference plate 504 and the longitudinal positioning plate 507, thereby directly converting it into the door panel length value, providing the core basis for the length qualification judgment.

[0035] Specifically, such as Figure 5 As shown, a fixing plate 6 is fixedly connected to the front side of the support frame 3, and a mounting plate 7 is provided at the bottom of the fixing plate 6. A proximity sensor 8 is fixedly installed at the bottom of the mounting plate 7.

[0036] Specifically, such as Figure 5 As shown, an electric push rod 9 is fixedly installed on the top of the fixed plate 6. The telescopic end of the electric push rod 9 passes through the fixed plate 6 and is fixedly connected to the top of the mounting plate 7.

[0037] In this embodiment: Through the above settings, the fixing plate 6 can provide a stable support foundation for the electric push rod 9, the mounting plate 7, and the proximity sensor 8, ensuring that the relevant components remain in a stable position during the detection process, avoiding displacement due to vibration or force, and ensuring the reliability of signal detection; the mounting plate 7 is used to support the proximity sensor 8, providing a suitable mounting surface for the proximity sensor 8, and connecting the electric push rod 9 and the proximity sensor 8, allowing the proximity sensor 8 to be aligned with the door panel on the conveyor belt 2 in a reasonable posture, accurately capturing the door panel position signal; the proximity sensor 8 is the core component for door panel positioning detection. When the door panel moves with the conveyor belt 2 to the preset position of the width detection station, the proximity sensor... Sensor 8 can quickly sense the presence of the door panel and output a "position trigger signal," which is fed back to the control system in real time. This provides precise signal commands for subsequent detection actions such as lifting and fixing, and base plate bonding, preventing misalignment between the detection action and the door panel position. The electric push rod 9 can provide lifting drive force and can precisely adjust the height of the mounting plate 7 and the proximity sensor 8 according to the different thicknesses of the door panel. This ensures that the proximity sensor 8 is always at the optimal sensing distance, preventing false triggering of the sensor due to an excessively thick door panel and preventing the sensor from failing to sense due to an excessively thin door panel. This significantly improves the adaptability of the device to different door panel specifications and ensures accurate triggering of the position signal when detecting various types of door panels.

[0038] Specifically, such as Figure 6 As shown, the top of the inner wall of the first U-shaped frame 401 and the second U-shaped frame 502 are both provided with guide grooves 10, and a slide rod 11 is fixedly connected inside the guide groove 10.

[0039] Specifically, such as Figure 6 As shown, guide blocks 12 are fixedly connected to the top of the transverse reference plate 403, the transverse positioning plate 406, the longitudinal positioning plate 507, and the longitudinal reference plate 504. The guide blocks 12 are slidably connected to the surface of the slide rod 11.

[0040] In this embodiment: Through the above settings, the guide groove 10 can provide a stable installation space for the slide rod 11, ensuring that the slide rod 11 remains in a fixed position during the detection process; the slide rod 11 has a smooth and flat surface, which can cooperate with the guide block 12 to form a precise sliding guide structure, providing a clear trajectory for the movement of the transverse reference plate 403, transverse positioning plate 406, longitudinal positioning plate 507 and longitudinal reference plate 504, avoiding transverse offset, tilting or jamming, thereby significantly improving the dimensional detection accuracy and stability of the entire detection device.

[0041] Specifically, such as Figure 2 As shown, a lifting cylinder 13 is fixedly installed at the bottom of the inner wall of the conveyor frame 1. The telescopic end of the lifting cylinder 13 is fixedly connected to a top plate 14, and the surface of the top plate 14 is coated with an anti-slip coating.

[0042] In this embodiment: With the above settings, after receiving the "door panel in position signal" from the proximity sensor 8, the lifting cylinder 13 can quickly output a stable upward driving force to drive the top plate 14 to rise precisely. After the top plate 14 rises, it will directly contact the bottom of the door panel. Its flat surface can provide uniform support force for the door panel, ensuring that the door panel remains horizontal after being lifted, avoiding tilting or displacement of the door panel due to uneven force. At the same time, the anti-slip coating on the surface of the top plate 14 can greatly increase the friction with the bottom of the door panel, effectively preventing the door panel from sliding or misaligning during the detection process, and ensuring that the door panel is always in the preset detection position.

[0043] Working Principle: First, the door panel to be tested is placed on conveyor belt 2. Then, conveyor belt 2 starts and smoothly transports the door panel to the testing station. When the door panel moves to the preset position of the width testing station, proximity sensor 8 quickly senses the door panel and immediately outputs a "position trigger signal" to the control system. Conveyor belt 2 then stops running. When the control system receives the position signal, it instructs lifting cylinder 13 to start. Lifting cylinder 13 outputs upward driving force, driving top plate 14 to rise smoothly, lifting the door panel off the surface of conveyor belt 2 and keeping it horizontal. Then, first cylinder 402 drives transverse reference plate 403 to move quickly along slide bar 11 until it is tightly attached to one side of the door panel, forming a reference surface for width detection. Subsequently, first servo motor 404 starts, driving first stud 405 to rotate precisely, driving transverse positioning plate 406 to move smoothly to the other side of the door panel until it is tightly attached to the door panel. At this time, first displacement sensor 407 on transverse reference plate 403 can collect the distance data between transverse reference plate 403 and transverse positioning plate 406 in real time and directly convert the distance data into... The width of the door panel is measured and transmitted to the control system for storage and analysis. After the width detection is completed, the lifting cylinder 13 drives the top plate 14 to reset, while the conveyor belt 2 continues to transport the door panel backward. When the door panel moves to the preset position of the width detection station, the proximity sensor 8 will quickly sense the door panel and restart the lifting cylinder 13, causing the lifting cylinder 13 to drive the top plate 14 to rise smoothly, lifting the door panel away from the surface of the conveyor belt 2 and keeping it horizontal. Then, the second cylinder 503 will push the longitudinal reference plate 504 to move along the slide bar 11, tightly fitting with one end of the door panel to form a length detection reference. The second servo motor 505 drives the second stud 506 to rotate, which will drive the longitudinal positioning plate 507 to move precisely to the other end of the door panel and fit it. The second displacement sensor 508 on the longitudinal positioning plate 507 can collect the distance data between the longitudinal reference plate 504 and the longitudinal positioning plate 507 and convert it into the door panel length value, which is synchronously transmitted to the control system. Finally, the control system will compare the collected width and length data with the preset standard specifications to quickly determine whether the door panel is qualified.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
