Description

Technical Field

[0001] This utility model relates to the field of glass bottle detection technology, and in particular to a glass bottle detection device with positioning function. Background Technology

[0002] As a commonly used container, the quality and safety of glass bottles are of paramount importance. Scratches, cracks, and other defects on the exterior, as well as the presence of foreign objects inside, all require rigorous testing. Currently, the industry primarily uses photographic inspection for quality control of glass bottles. This involves capturing images of the bottle with a camera and then analyzing these images using image processing technology to determine its compliance. However, existing photographic inspection devices have limitations in practical applications. During transport on conveyor lines, glass bottles are susceptible to variations in speed and vibration, resulting in inconsistent positions. They may be tilted to one side or at an angle. This uncertainty makes it difficult for the camera to accurately capture the bottle's complete appearance and internal structure, leading to missed or false detections. This severely impacts the accuracy and effectiveness of the inspection, failing to meet the demands of high-precision testing. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that existing technologies make it difficult to center the position of glass bottles, which makes it difficult for cameras to accurately capture the complete appearance and internal condition of glass bottles, and easily leads to problems such as missed detection and false detection. Therefore, this invention proposes a glass bottle detection device with positioning function.

[0004] To solve the above-mentioned technical problems, the present invention provides a glass bottle detection device with positioning function, including a conveyor line. A detection mechanism is installed in the middle of the upper surface of the conveyor line. Multiple placement positions for placing glass bottles to be detected are fixedly installed on the conveyor belt of the conveyor line at equal intervals. Each placement position is provided with a clamping assembly for fixing the glass bottle to be detected. The clamping assembly includes two clamping plates slidably disposed on the placement position and a power mechanism for pushing the clamping plates to move on the side of the two clamping plates that are far apart from each other.

[0005] Furthermore, the power mechanism includes a first support plate, a sliding rod, a support block, a first spring, and a second support plate; the first support plate is fixedly connected to the upper surface of the placement position and located on one side of the clamping plate, the sliding rod slides through the first support plate and one end of the sliding rod is fixedly connected to the clamping plate, the support block is slidably connected to the surface of the placement position and fixedly connected to the end of the sliding rod away from the clamping plate, the second support plate is fixedly connected to the end of the placement position, and the first spring is disposed between the support block and the second support plate to push the two clamping plates to move toward each other.

[0006] Furthermore, each of the power mechanisms is provided with a clamping release component, and the conveyor line is provided with a trigger corresponding to the clamping release component. When the clamping release component moves to the position of the trigger, the clamping release component cooperates with the trigger to drive the two clamping plates to move in a direction away from each other to release the clamping of the glass bottle.

[0007] Furthermore, the upper surface of the support block is an inclined surface, and the clamping release assembly includes a pressing block, a connecting plate, a triangular prism, a support rod, and a second spring that are slidably connected to the inclined surface of the support block; the pressing block has a channel for the sliding rod to move, the pressing block is fixedly connected to the triangular prism through the connecting plate, the bottom end of the support rod is fixedly connected to the top end of the second support plate, the triangular prism is slidably sleeved on the top of the support rod, and the second spring is sleeved on the outside of the support rod with its two ends abutting against the triangular prism and the second support plate, respectively.

[0008] Furthermore, the triangular prism has a through hole for the support rod to pass through, the top of the support rod is provided with a limiting part, and the bottom inner wall of the through hole is provided with an annular protrusion that matches the limiting part.

[0009] Furthermore, the clamping release assembly also includes a connecting plate, a triangular prism, a support rod, and a second spring; the pressing block is fixedly connected to the triangular prism through the connecting plate, the bottom end of the support rod is fixedly connected to the top end of the second support plate, the triangular prism is slidably sleeved on the top of the support rod, and the second spring is sleeved on the outside of the support rod with its two ends abutting against the triangular prism and the second support plate respectively.

[0010] Furthermore, the trigger includes a mounting bracket fixedly installed on both sides of the conveyor line and a trigger baffle fixedly connected to the mounting bracket.

[0011] Furthermore, the front end of the trigger baffle is provided with an inclined trigger surface that is adapted to the inclined surface of the triangular prism.

[0014] Furthermore, the detection mechanism includes a U-shaped frame fixedly connected to the side plate of the conveyor line and a camera mounted on the inner top wall of the U-shaped frame.

[0015] Compared with existing technologies, this utility model provides a glass bottle detection device with positioning function. By setting a clamping component with a power mechanism at the placement position on the conveyor line, the clamping plate is automatically centered and clamped by a spring, which solves the problem of positional deviation during conveying and ensures accurate imaging by the detection mechanism to reduce missed detections and false detections. With the clamping release component and trigger, glass bottles can be easily loaded and unloaded without affecting the conveying efficiency. Moreover, the V-groove and elastic buffer pad are suitable for glass bottles of different specifications and avoid damage. The overall structure is simple, reliable, and low in cost, effectively meeting the requirements of high-precision detection. Attached Figure Description

[0021] The following detailed implementation methods further illustrate the following: Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides the following technical solution: a glass bottle detection device with positioning function, including a conveyor line 1, a detection mechanism 2 installed on the conveyor line 1, and multiple equally spaced placement positions 3 for placing glass bottles to be detected fixedly installed on the conveyor belt of the conveyor line 1. Each placement position 3 is provided with a clamping assembly 4 for fixing the glass bottle to be detected. The clamping assembly 4 includes two clamping plates 41 slidably disposed on the placement position 3 and a power mechanism 42 disposed on one side of the two clamping plates 41 away from each other for pushing the clamping plates 41 to move. This utility model solves the problem of positional offset during transportation by setting the clamping assembly 4 with the power mechanism 42 on the placement position 3, and automatically centering and clamping the glass bottle by the clamping plates 41, thus ensuring accurate imaging by the detection mechanism and reducing missed detections and false detections.

[0022] In this embodiment, the detection mechanism 2 includes a U-shaped frame 21 fixedly connected to the side plate of the conveyor line 1 and a camera 22 mounted on the inner top wall of the U-shaped frame 21. Specifically, both ends of the U-shaped frame 21 are fixed to the conveyor line 1 by bolts and span the conveyor line 1. The lens of the camera 22 mounted on its inner top wall faces the glass bottle on the placement position 3. The camera 22 can be connected to an image processing system. After the glass bottle is clamped and positioned, the camera 22 captures an image of the glass bottle and transmits it to the system for analysis and detection. The U-shaped frame 21 provides a stable mounting platform for the camera 22, ensuring a fixed shooting angle. The front side of the detection mechanism 2 is the loading area, and the rear side is the unloading area. In use, the power to the conveyor line 1 is first turned on, causing the conveyor belt to drive the multiple placement positions 3 to move at a set speed.

[0023] When the placement position 3 moves to the loading area, the operator needs to release the clamping plate 41 to load the glass bottle. After loading, the clamping plate 41 is moved by the power mechanism 41 to clamp the glass bottle. In this embodiment, the power mechanism 42 includes a first support plate 421, a sliding rod 422, a support block 423, a first spring 424, and a second support plate 425. The first support plate 421 is fixedly connected to the upper surface of the placement position 3 and located on one side of the clamping plate 41. The sliding rod 422 slides through the first support plate 421, and one end of the sliding rod 422 is fixedly connected to the clamping plate 41. The support block 423 is slidably connected to the surface of the placement position 3 and fixedly connected to the end of the sliding rod 422 away from the clamping plate 41. The second support plate 425 is fixedly connected to the end of the placement position 3. The first spring 424 is disposed between the support block 423 and the second support plate 425 to push the two clamping plates 41 to move toward each other. It should be noted that in this embodiment, the placement position 3 can be a rigid metal plate. When the placement position 3 is a rigid plate, the smaller its width, the narrower the contact area with the conveyor belt (or chain plate) when the conveyor line 1 turns at both ends, and the weaker the restriction effect on the bending deformation of the conveyor belt. On the other hand, the larger the outer diameter of the drive roller, the larger its radius of curvature, and the smaller the bending angle of the conveyor belt when turning. The rigidity resistance of the rigid plate when the conveyor belt bends will be significantly reduced. The combination of the two can reduce the conflict between the rigid plate and the movement trajectory of the conveyor line. Specifically, the width of the placement position 3 can be designed to be less than 1 / 3 of the outer diameter of the drive roller. The narrower width allows the rigid plate to occupy only a small part of the belt surface when the belt turns, and the rest of the belt can bend freely, avoiding belt jamming caused by excessive rigidity of the rigid plate. In the power mechanism 42, the first support plate 421 is fixedly connected to the upper surface of the placement position 3 by welding or bolts, and a certain gap is left between it and the clamping plate 41 to ensure that the clamping plate 41 can move freely. The sliding connection between the sliding rod 422 and the first support plate 421 can be achieved by opening a through hole in the support plate 421, through which the sliding rod 422 passes. The sliding rod 422 is fixed to the clamping plate 41 by welding or threading. In this embodiment, the sliding rod 422 is a rectangular sliding rod, and its sliding connection with the first support plate 421 is achieved by opening a rectangular through hole in the first support plate 421 that matches the cross-section of the sliding rod 422. After passing through the rectangular through hole, the sliding rod 422 is fixed to the clamping plate 41 by welding or threading. The rectangular cross-section design prevents the sliding rod 422 from rotating during sliding, ensuring that the moving direction of the clamping plate 41 remains stable.The bottom of the support block 423 may be provided with a slider, and the surface of the placement position 3 is provided with a corresponding sliding groove, so that the support block 423 can slide smoothly. The support block 423 and the end of the sliding rod 422 away from the clamping plate 41 are welded and fixed. The second support plate 425 is fixed to the end of the placement position 3 by welding and is arranged opposite to the support block 423. One end of the first spring 424 is welded or hooked to the support block 423, and the other end is connected to the second support plate 425 in the same way. In the natural state, the first spring 424 is in a compressed state, which will push the support block 423, thereby driving the sliding rod 422 and the clamping plate 41, so that the two clamping plates 41 move in a direction closer to each other to clamp the glass bottle.

[0024] To improve the clamping effect, V-shaped grooves 411 are formed at the adjacent ends of the two clamping plates 41, and elastic buffer pads (not shown in the figure) are fixedly connected to the inner sidewalls of the V-shaped grooves 411. The included angle of the V-shaped grooves 411 formed at the adjacent ends of the two clamping plates 41 can be designed according to the size range of common glass bottles, generally 90-120 degrees. When the glass bottle is placed on the placement position 3, the two sidewalls of the V-shaped grooves 411 can contact the surface of the glass bottle, automatically centering the glass bottle and ensuring that the central axis of the glass bottle is aligned with the detection center of the detection mechanism 2. This design can solve the positioning problem of glass bottles of different diameters on the placement position 3, ensuring that the center position of the glass bottle is consistent during detection and improving the accuracy of detection. In this embodiment, the elastic buffer pads can be made of rubber or silicone and are glued to the inner sidewalls of the V-shaped grooves 411. It has a certain degree of elasticity, and can deform when clamping glass bottles, increasing the contact area with the glass bottles and improving the stability of clamping, while avoiding excessive clamping force that could scratch or indent the surface of the glass bottles.

[0025] Once the glass bottle to be inspected passes through the inspection mechanism 2, the inspection is complete, and unloading is required in the unloading area. To facilitate unloading by staff, each power mechanism 42 is equipped with a clamping release component 5, and the conveyor line 1 is equipped with a trigger 6 corresponding to the clamping release component 5. When the clamping release component 5 moves to the position of the trigger 6, the clamping release component 5 and the trigger 6 cooperate to drive the two clamping plates 41 to move away from each other to release the clamping of the glass bottle. Specifically, the upper surface of the support block 423 is an inclined surface, and the clamping release component 5 includes a pressing block 51, a connecting plate 52, a triangular prism 53, a support rod 54, and a second spring 55; the pressing block 51 is slidably connected to the inclined surface of the support block 423, and the pressing block 51 is provided with a channel 511 for the sliding rod to move. The extrusion block 51 is fixedly connected to the triangular prism 53 via the connecting plate 52. The bottom end of the support rod 54 is fixedly connected to the top end of the second support plate 425. The triangular prism 53 is slidably sleeved on the top of the support rod 54. The second spring 55 is sleeved on the outside of the support rod 54, with its two ends abutting against the triangular prism 53 and the second support plate 425, respectively. The upper surface of the support block 423 is an inclined surface, providing guidance for the sliding of the extrusion block 51. The extrusion block 51 of the clamping release assembly 5 is slidably connected to the inclined surface of the support block 423. The channel 511 inside the extrusion block 51 allows the sliding rod 422 to move, preventing interference between the extrusion block 51 and the sliding rod 422 when the extrusion block 51 moves. The extrusion block 51 is fixed to the triangular prism 53 via the connecting plate 52, so that the movement of the triangular prism 53 can drive the extrusion block 51 to move. The bottom end of the support rod 54 is fixed to the top end of the second support plate 425, providing sliding support for the triangular prism 53. The triangular prism 53 is slidably sleeved on the top of the support rod 54. The second spring 55 is sleeved on the outside of the support rod 54, with its two ends abutting against the triangular prism 53 and the second support plate 425 respectively. When the triangular prism 53 is not subjected to triggering force, the second spring 55 can push it to reset. When the trigger 6 acts on the triangular prism 53, the triangular prism 53 drives the connecting plate 52 and the pressing block 51 to move. The pressing block 51 slides on the inclined surface of the support block 423, pushing the support block 423 to move, thereby causing the clamping plates 41 to move away from each other, thus releasing the clamp. When the placement position 3 rotates to the bottom of the conveyor line 1 along with the conveyor belt, in order to prevent the triangular prism 53 from falling off the support rod 54, in this embodiment, a through hole 531 is provided on the triangular prism 53 for the support rod 54 to pass through. The top of the support rod 54 is provided with a limiting part (not shown in the figure), and the bottom inner side wall of the through hole 531 is provided with an annular protrusion (not shown in the figure) that matches the limiting part 541.The through hole 531 on the triangular prism 53 allows the support rod 54 to pass through. The limiting part 541 at the top of the support rod 54 cooperates with the annular protrusion on the inner sidewall of the bottom of the through hole 531, which can limit the sliding range of the triangular prism 53 on the support rod 54, prevent the triangular prism 53 from falling off the support rod 54, and ensure the stability of the clamping release assembly 5 structure.

[0026] In this embodiment, the trigger 6 includes a mounting bracket 61 fixedly installed on both sides of the conveyor line 1 and a trigger baffle 62 fixedly connected to the mounting bracket 61. The mounting bracket 61 is fixed to both sides of the conveyor line 1, providing mounting support for the trigger baffle 62. The trigger baffle 62 is fixedly connected to the mounting bracket 61 and can accurately cooperate with the moving clamping release component 5, ensuring reliable triggering action and solving the problems of trigger installation, fixing, and positioning. The front end of the trigger baffle 62 has an inclined trigger surface 621 adapted to the inclined surface of the triangular prism 53. Simultaneously, the inclined trigger surface 621 at the front end of the trigger baffle 62 adapts to the inclined surface of the triangular prism 53, allowing the triangular prism 53 to interact smoothly with the trigger baffle 62 when in contact, reducing collisions and wear, making the triggering process smoother, and solving the problems of jamming and wear caused by mismatched contact surfaces during triggering.

[0027] This utility model discloses a glass bottle inspection device with positioning function, which has the following beneficial effects: By setting a clamping assembly with a power mechanism at each placement position on the conveyor line, the continuous pushing force of the first spring on the support block drives the sliding rod and clamping plate to automatically move towards the center, which can stably clamp the glass bottle and achieve precise centering positioning. This completely solves the problem of positional deviation or skew caused by speed fluctuations and vibrations during glass bottle conveying, ensuring that the camera of the inspection mechanism can always capture the complete appearance and internal state of the glass bottle, reducing missed detections and false detections from the root, and significantly improving inspection accuracy. At the same time, the device is equipped with a clamping release assembly and a trigger. When the placement position moves to the loading and unloading area, the inclined triggering surface of the trigger baffle cooperates with the inclined surface of the triangular prism, and the support block is pushed to move by the squeezing block, so that the clamping plate automatically separates to release the clamp, which facilitates the workers to quickly complete the loading or unloading operation and avoids the impact of fixed structure on the continuous operation efficiency of the conveyor line. Furthermore, the V-groove design of the clamping plate can accommodate glass bottles of different diameters, ensuring stable centering for all bottle types. The elastic buffer pads within the grooves effectively cushion the clamping force, preventing scratches or damage to the glass bottle surface. The entire device relies on basic components such as springs, sliding rods, and support plates to achieve its functions, eliminating the need for complex electrical control systems. This not only makes it simple, reliable, easy to manufacture and maintain, but also reduces production costs, fully meeting the high-precision testing needs of glass bottles in the food and pharmaceutical industries.

[0028] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
