Description

Technical Field

[0001] This utility model relates to the field of woven bag inspection technology, specifically a woven bag appearance inspection device. Background Technology

[0002] Visual inspection of woven bags is a crucial step in ensuring their quality, compliance with standards, and fulfillment of usage requirements. The appearance quality of woven bags includes checking for flatness, damage, holes, broken threads, loose threads, stains, and color variations. These defects affect the product's aesthetics and performance. In recent years, machine vision-based surface defect detection systems have been widely applied in woven bag production to improve inspection efficiency and accuracy.

[0003] Appearance inspection devices for woven bags typically include a machine body and a camera to achieve high-precision detection of surface defects. During the inspection process, the woven bags are usually positioned and moved by conveyor rollers or a sliding table mechanism on the machine body. As the plates move, the camera captures images of the woven bags, which are then analyzed using image processing algorithms. Through these algorithms, the system can identify the surface of the woven bags and classify them according to preset judgment criteria. When a non-conforming woven bag is detected, the system issues an alarm signal and feeds the inspection results back to the production control system.

[0004] However, traditional woven bag appearance inspection devices are easily affected by equipment vibration (such as production line mechanical vibration and motor operation) in industrial environments. The camera and the frame are fixed and locked with screws, which is not only difficult to disassemble, but also causes the camera to shake with the frame, affecting the image clarity and thus reducing the detection accuracy of the device.

[0005] Based on this, the present invention designs a woven bag appearance inspection device to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A connecting assembly is fixedly installed on the frame, the connecting assembly including an upper cover, a lower cover, a spring, and a limiting block. The lower cover is fixedly installed on the frame, and a limiting groove and a clearance groove are formed on its upper surface. One end of the spring is fixedly connected to the bottom of the clearance groove, and the other end is connected to the upper cover. The limiting block is fixed to the lower surface of the upper cover. When the limiting block is embedded in the limiting groove, the upper cover closes on top of the lower cover. A connecting piece is fixedly installed on the camera. The connecting piece is detachably inserted between the upper cover and the lower cover and is pressed and fixed by the elastic force of the spring. A damping layer is provided on the side wall of the limiting groove, and the damping layer is made of silicone material.

[0007] By adopting the above technical solution, the upper cover is pulled up to separate the upper and lower covers. Then, the connecting piece is placed on the lower cover, and the upper cover is released, causing the spring to pull the upper cover back onto the lower cover. The upper and lower covers clamp and fix the connecting piece. The damping layer absorbs the collision energy of the limiting block and the limiting groove, reducing camera vibration caused by high-frequency vibration. This avoids the problem of tight fit between the frame and the camera caused by traditional screw fixing, and enables quick assembly and disassembly of the camera without the need for additional tools, facilitating camera maintenance and improving the camera's detection accuracy.

[0008] Preferably, the frame is equipped with a vibration sensor and a controller, the vibration sensor is electrically connected to the controller, and the controller is electrically connected to the camera.

[0009] By adopting the above technical solution, vibration intensity is detected in real time. The controller controls the camera based on the vibration data and triggers image re-capture, reducing the impact of vibration on camera testing and further improving the camera's shooting accuracy.

[0010] Preferably, the contact surfaces of the connecting piece with the upper and lower covers are provided with anti-slip textures.

[0011] By adopting the above technical solution, friction is increased to prevent the camera from sliding horizontally in a vibrating environment, thereby further improving the camera's stability.

[0012] Preferably, a guide post is provided between the upper cover and the lower cover, and an anti-detachment block is fixedly provided on the top of the guide post.

[0013] By adopting the above technical solution, the upper and lower covers can be opened and closed accurately through the guide post, avoiding misalignment between the upper and lower covers.

[0014] Preferably, a handle is fixedly provided on the upper surface of the cover.

[0015] By adopting the above technical solution, it is easier for users to lift the top cover, thus improving the ease of use of the top cover.

[0016] In summary, this application has the following beneficial technical effects: the upper cover is pulled up to separate the upper and lower covers, the connecting piece is placed on the lower cover, the upper cover is released, and the spring pulls the upper cover back onto the lower cover. The upper and lower covers clamp and fix the connecting piece. The damping layer absorbs the collision energy of the limiting block and the limiting groove, reduces camera vibration caused by high-frequency vibration, avoids the problem of tight fit between the frame and the camera caused by traditional screw fixing, and enables quick assembly and disassembly of the camera without the need for additional tools, which facilitates camera maintenance and improves the detection accuracy of the camera.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] A woven bag appearance inspection device includes a frame 1 and a camera 2. A connecting assembly is fixedly installed on the frame 1. The connecting assembly includes an upper cover 5, a lower cover 10, a spring 11, and a limiting block 7. The lower cover 10 is fixedly installed on the frame 1. A limiting groove 15 and a clearance groove 12 are formed on its upper surface. One end of the spring 11 is fixedly connected to the bottom of the clearance groove 12, and the other end is connected to the upper cover 5. The limiting block 7 is fixed to the lower surface of the upper cover 5. A connecting piece 9 is fixedly installed on the camera 2. A connecting hole is provided between the upper cover 5 and the lower cover 10. The connecting piece 9 can be detachably inserted into the connecting hole between the upper cover 5 and the lower cover 10. A damping layer 14 is provided on the side wall of the limiting groove 15. The damping layer 14 is made of silicone material.

[0023] In use, pull the top cover 5 upwards to stretch the spring 11, separating the top cover 5 from the bottom cover 10. Then place the connecting piece 9 on the bottom cover 10, aligning the bent part of the connecting piece 9 with the limiting groove 15, and then release the top cover 5. The spring 11 begins to contract, pulling the top cover 5 back. The limiting block 7 on the top cover 5 then presses the connecting piece 9 against the limiting groove 15. When the limiting block 7 presses the connecting piece 9 against the limiting groove 15, the damping layer 14 can absorb the collision energy between the limiting block 7 and the limiting groove 15, reducing the vibration of the camera 2 caused by high-frequency vibration. This allows the camera 2 to be more stably connected to the frame 1, and the camera 2 can be quickly fixed to the frame 1 without the need for additional tools. The operation is simple and convenient, reducing the vibration of the camera 2 caused by high-frequency vibration and improving the detection accuracy of the camera 2.

[0024] The frame 1 is equipped with a vibration sensor 4 and a controller 3. The vibration sensor 4 is electrically connected to the controller 3, and the controller 3 is electrically connected to the camera 2. When the device is in use, the frame 1 will vibrate. The vibration sensor 4 detects the vibration frequency of the frame 1 in real time. When a large degree of vibration is detected in the frame 1, the vibration sensor 4 sends a signal to the controller 3. The controller 3 then dynamically adjusts the function of triggering image re-capture based on the vibration data, further improving the detection accuracy of the camera 2.

[0025] The contact surfaces of the connecting piece 9 with the upper cover 5 and the lower cover 10 are provided with anti-slip textures 8. The anti-slip textures 8 are distributed on the inner wall of the connecting hole. When the connecting piece 9 is inserted into the connecting hole, the anti-slip textures 8 abut against the connecting piece 9, making the connection between the connecting piece 9 and the upper cover 5 and the lower cover 10 more stable. A guide post 6 is provided between the upper cover 5 and the lower cover 10. An anti-detachment block 13 is fixedly provided on the top of the guide post 6. When the upper cover 5 moves up and down, it slides along the guide post 6, which improves the accuracy of the upper cover 5 closing, until the top of the upper cover 5 abuts against the anti-detachment block 13, so that the connecting component can maintain its integrity and prevent the upper cover 5 from being lost. A handle 16 is fixedly provided on the upper surface of the upper cover 5, which makes it easy for the user to lift the upper cover 5 and improves the ease of use of the connecting component.

[0026] The implementation principle of this embodiment is as follows: When in use, the upper cover 5 is pulled upward by the handle 16, so that the spring 11 is stretched and the upper cover 5 is separated from the lower cover 10. Then, the connecting piece 9 is placed on the lower cover 10, and the bent part on the connecting piece 9 is aligned with the limiting groove 15 before being lowered. When the limiting block 7 presses the connecting piece 9 against the limiting groove 15, the damping layer 14 can absorb the collision energy between the limiting block 7 and the limiting groove 15. Then, the upper cover 5 is released, the spring 11 begins to contract, and the upper cover 5 is pulled back. The limiting block 7 on the upper cover 5 then presses the connecting piece 9 against the limiting groove 15. The anti-slip texture 8 in the connecting hole presses against the connecting piece 9, so that the connecting piece 9 can be quickly fixed and the camera 2 can be quickly fixed on the frame 1.

[0027] After the device is started, the frame 1 will vibrate. The vibration frequency of the frame 1 is detected in real time by the vibration sensor 4. When the frame 1 vibrates to a large extent, the vibration sensor 4 sends a signal to the controller 3. The controller 3 then dynamically adjusts the function of triggering image re-capture based on the vibration data, which ensures the detection accuracy of the device.
