Abstract
Description
Technical Field
[0001] This utility model relates to the field of variable angle rotation mechanism technology, and in particular to a variable angle offset rotation mechanism for detecting foreign objects inside bottles. Background Technology
[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.
[0003] Foreign matter detection inside bottles is a crucial quality control and safety assurance process in modern industrial production, particularly in the food, beverage, pharmaceutical, cosmetic, and chemical industries. This is especially true in the large-volume parenteral solutions industry, where safety requirements are extremely stringent, demanding very high precision in detecting visible foreign matter in injectables, oral solutions, and eye drops. Conventional methods for detecting foreign matter inside or on the surface of liquids involve suspending or clamping the bottle and rotating it to allow the foreign matter to move along a certain trajectory before photographing it. However, for foreign matter such as protein flocculent fibers floating on the surface, this method fails to capture their movement trajectory even after rotation.
[0004] The prior art discloses an automatic detection method and device for high-density, high-mass foreign objects in liquor, as disclosed in the invention patent application with publication number CN108535277A. This method includes the following steps: preparing for detection by installing the bottle of liquor after it has been filled at the starting point of a mechanical transmission mechanism; detecting high-density, high-mass foreign objects by setting a first anomaly detection station and a second anomaly detection station at the initial end of the mechanical transmission mechanism; and comparing the results from the first and second anomaly detection stations to obtain the detection result. However, the aforementioned technical solutions and related technologies still have many problems, such as the inability to adjust the angle of the bottle to be detected in real time, thus failing to transfer foreign objects such as protein flocculent fibers floating on the liquid surface into the liquid, and consequently failing to effectively improve the detection effect. Utility Model Content
[0005] The purpose of this invention is to provide a variable-angle offset rotation mechanism for detecting foreign objects inside bottles, which solves the technical problems of low detection efficiency and poor detection accuracy caused by the difficulty in detecting foreign objects floating on the liquid surface inside the bottle.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A variable-angle bias rotation mechanism for detecting foreign objects inside a bottle includes:
[0008] The support is fixedly installed relative to the rotary table;
[0009] A rotating plate that is rotatably mounted relative to the support;
[0010] An angle adjustment power unit is fixedly installed relative to the rotary table, and its power unit is rotatably installed relative to one end of the rotating plate.
[0011] A spin assembly is mounted on the other end of a rotating plate and is provided with a clamping unit for clamping and releasing the bottle to be tested, and the clamping unit is driven to rotate by a rotating power unit that is fixedly mounted relative to the rotating plate.
[0012] The angle adjustment power unit drives the rotating plate to rotate relative to the support, thereby adjusting the tilt angle of the bottle to be tested.
[0013] Furthermore, the support includes a double-limit support and a single-limit support. One end of both the double-limit support and the single-limit support is fixedly installed relative to the rotary table. The other end of the double-limit support is provided with a first limit end and a second limit end forming a U-shape. The single-limit support is provided with a first limit end, which is used to limit one side of the rotating plate, and the second limit end is used to limit the other side of the rotating plate.
[0014] Furthermore, the rotating plate includes a narrow section and a wide section. The two sides of the narrow section are rotatably mounted to a double-limiting support and a single-limiting support via a rotating shaft, respectively. The first limiting end and the second limiting end limit the upper and lower surfaces of the width of the rotating plate, respectively.
[0015] Furthermore, the angle adjustment power unit is a linear drive component, and its power end is rotatably mounted relative to the narrow part of the rotating plate.
[0016] Furthermore, the rotational power unit is installed on the narrow part of the rotating plate, and the spin assembly is installed on the wide part of the rotating plate. The power end of the rotational power unit drives the clamping unit of the spin assembly to rotate relative to the rotating plate through the belt assembly.
[0017] Furthermore, the belt assembly includes a driving pulley, a passive pulley of the clamping unit, and a belt that drives synchronously with both, with the driving pulley and the rotating plate being rotatably mounted together.
[0018] Furthermore, the belt assembly also includes a tensioning pulley, the position of which is adjusted by an adjustment mechanism to adjust the belt tension.
[0019] Furthermore, the adjustment mechanism includes a slide plate slidably mounted on the turntable, and the tension wheel is rotatably mounted on the slide plate.
[0020] Furthermore, the slide plate is provided with an elongated hole, on which an adjusting screw is installed. The adjusting screw passes through the elongated hole and is installed on the rotating plate to achieve relative fixation between the slide plate and the rotating plate.
[0021] Furthermore, the tensioning wheel is a bearing or a pulley.
[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0023] (1). This utility model drives the rotating plate to rotate by setting an angle adjustment power unit. When the rotating plate rotates, it drives the bottle to be tested on the spin assembly to move synchronously, thereby realizing the angle adjustment of the bottle to be tested. The tilt angle of the bottle to be tested can be adjusted according to the needs. At the same time, the rotation power unit drives the spin assembly to realize the rotation of the bottle to be tested, thereby causing the protein flocculent fibers floating on the liquid surface to be detached from the adsorption force of the liquid surface and rotated into the liquid under the action of vertical downward attraction and tilted rotation centrifugal force, thereby eliminating the influence of drug floating bubbles on the liquid surface on foreign matter detection.
[0024] (2). By setting up double limit supports and single limit supports, this utility model effectively limits the rotation, which is beneficial to improving the overall stability of the mechanism. Attached Figure Description

The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0042] To address the limitations of existing technologies, this embodiment provides a technical solution. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0043] This invention addresses the problem that in existing technologies, when detecting foreign objects in a bottle of liquid, the bottle to be tested needs to be rotated 600° to move floating foreign objects on the surface of the liquid into the liquid inside the bottle for detection. However, a common problem in existing technologies is that when the bottle is rotated, the foreign objects cannot be effectively moved into the liquid, resulting in a need to improve both detection efficiency and accuracy.
[0044] An improved variable-angle offset rotation mechanism for detecting foreign objects inside bottles, addressing the aforementioned technical problems, is shown in the appendix. Figure 1-4 and appendix Figure 8-10 The system includes: a support 400, which is fixedly installed relative to a rotary table 700. The rotary table 700 is driven to rotate by another power mechanism; since this does not involve the technical points to be protected in this application, it will not be described in detail here. The support 400 includes a double-limiting support 401 and a single-limiting support 402. One end of both the double-limiting support 401 and the single-limiting support 402 is fixedly installed relative to the rotary table 700. This fixed installation can be understood as fastening with screws or using other methods. The other end of the double-limiting support 401 is... The first limiting end 4011 and the second limiting end 4012 form a U-shape. The single limiting support 402 is provided with the first limiting end 4011, which is used to limit one side of the rotating plate 300. The second limiting end 4012 is used to limit the other side of the rotating plate 300. It can be understood that the double limiting support 401 and the single limiting support 402 have the same structure except for the setting of the second limiting end 4012. By setting the double limiting support 401 and the single limiting support 402, the rotation is effectively limited, which helps to improve the overall stability of the mechanism.
[0045] See appendix Figure 3 and attached Figure 4A rotating plate 300 is rotatably mounted relative to a support 400. Specifically, the rotating plate 300 includes a narrow portion and a wide portion. The two sides of the narrow portion are rotatably mounted to a double-limit support 401 and a single-limit support 402 via rotating shafts, respectively. The first limiting end 4011 and the second limiting end 4012 limit the upper and lower surfaces of the width of the rotating plate 300, respectively. It can be understood that the two sides of the narrow portion of the rotating plate 300 are rotatably mounted to the support 400 via rotating shafts and bearings. Furthermore, a groove is provided on the wide portion of the rotating plate 300 at the position corresponding to the limiting position of the support 400, for cooperating with the first limiting end 4011 and the second limiting end 4012. A removable pad is installed in the groove. This pad can be removed after wear. The pad can also be made of vibration-damping material to reduce the buffering force and reduce noise generation.
[0046] See appendix Figure 1-4 An angle-adjusting power unit 100 is fixedly installed relative to the rotary table 700, and its power unit is rotatably installed relative to one end of the rotating plate 300. The angle-adjusting power unit 100 is a linear drive component, with its power end rotatably installed relative to the narrow portion of the rotating plate 300. The angle-adjusting power unit 100 drives the rotating plate 300 to rotate relative to the support 400, thereby adjusting the tilt angle of the bottle 600 to be tested. It can be understood that the angle-adjusting power unit 100 preferably uses a cylinder, but a motor or hydraulic cylinder can also be used. When the power end of the angle-adjusting power unit 100 performs a linear action, the rotating plate 300 rotates around its connection point with the support 400, thus achieving the rotation of the rotating plate 300.
[0047] See appendix Figure 3-7A spin assembly 500 is installed at the other end of the rotating plate 300 and is equipped with a clamping unit for clamping and releasing the bottle 600 to be tested. This clamping unit is driven to rotate by a rotational power unit 200 fixedly installed relative to the rotating plate 300. Here, the rotational power unit 200 preferably uses a servo motor. The spin assembly 500 and the angle adjustment power unit 100 are located on opposite sides of the connection point between the rotating plate 300 and the support 400. The rotational power unit 200 is detachably installed on the rotating plate 300 by screws, or can be fixedly installed relative to it by other means. The rotating power unit 200 is installed on the narrow part of the rotating plate 300, and the self-rotating assembly 500 is installed on the wide part of the rotating plate 300. The power end of the rotating power unit 200 drives the clamping unit of the self-rotating assembly 500 to rotate relative to the rotating plate 300 through the belt assembly. It can be understood here that the belt assembly 306 includes a driving pulley 301, a driven pulley 507 of the clamping unit, and a belt 306 that drives synchronously with both. The driving pulley 301 and the rotating plate 300 are rotatably mounted together. This rotatable mounting can be understood as the driving pulley 301 being rotatably mounted to the rotating plate 300 through a bearing. The belt assembly 306 also includes a tensioning pulley 302, the position of which is adjusted by an adjusting mechanism to adjust the tension of the belt 306. The adjusting mechanism includes a sliding plate 303 slidably mounted on the rotating plate 300, and the tensioning pulley 302 is rotatably mounted on the sliding plate 303. The tensioning pulley 302 is a bearing or a pulley. The slide plate 303 is provided with an elongated hole 304, and an adjusting screw 305 is installed on the elongated hole 304. The adjusting screw 305 passes through the elongated hole 304 and is installed on the rotating plate 300 to achieve relative fixation between the slide plate 303 and the rotating plate 300.
[0048] See appendix Figure 5-7In this embodiment, there are two spin components 500. Each spin component 500 includes a fixed base 508 that is fixedly installed relative to the rotating plate 300, and a clamping power unit 501 that is fixedly installed relative to the fixed base 508. The clamping power unit 501 is a linear drive component. The clamping power unit 501 is fixedly installed relative to the fixed base 508 via a support rod 509. Here, the clamping power unit 501 is preferably a linear cylinder. The clamping power unit 501 drives the clamping part 505 of the clamping unit to clamp or release the bottle 600 to be tested. Specifically, the clamping unit further includes a transmission rod 502 that rotates and slides relative to the fixed base 508. This means that the transmission rod 502 and the fixed base 508 can both rotate and slide relative to each other; that is, the transmission rod 502 can move up and down relative to the fixed base 508. One end of the transmission rod 502 is rotatably mounted relative to the power end of the clamping power unit 501. This rotatable mounting means that the power end of the clamping power unit 501 is rotatably mounted relative to one end of the transmission rod 502 via a bearing seat 510. A bearing is provided inside the bearing seat 510 to enable the transmission rod 502 to rotate relative to the bearing seat 510, i.e., the transmission rod 502 is rotatably mounted relative to the power end of the clamping power unit 501. The other end of the transmission rod 502 is rotatably mounted to one end of two connecting parts 503. The connecting parts 503 are provided with… It is a long plate shape. The other ends of the two connecting parts 503 are rotatably installed with one end of the two rotating parts 504 respectively. The other ends of the two rotating parts 504 are fixedly installed relative to the clamping part 505. The relative fixed installation can be achieved by screw fastening or other methods. A fulcrum is provided between the two ends of the rotating part 504. It can be understood that the rotating part 504 rotates around the fulcrum, with one end rotatably installed with the connecting part 503 and the other end fixedly installed with the clamping part 505. The fulcrum is rotatably installed relative to the sliding sleeve 511. It can be understood that the fulcrum is rotatably installed on the sliding sleeve 511, so that the rotating part 504 rotates relative to the sliding sleeve 511 around the fulcrum. The sliding sleeve 511 is rotatably installed relative to the fixed seat 508. It can be understood that the sliding sleeve 511 and the fixed seat 508 are rotatably installed through a bearing. The transmission rod 502 and the sliding sleeve 511 are slidably mounted relative to each other. This means that the transmission rod 502 and the sliding sleeve 511 are slidably mounted relative to each other via a linear bearing or other linear type of sliding sleeve 511. A driven pulley 507, rotating synchronously with the sliding sleeve 511, is also fitted onto the outside of the sliding sleeve 511. This driven pulley 507 is fitted onto the outside of the sliding sleeve 511 and connected to the sliding sleeve 511 via a key. The driven pulley 507 is driven to rotate by the rotating power unit 200 via a belt 306. The pivot point of the rotating part 504 is rotatably mounted on the fixed frame 506, which is fixedly mounted relative to the sliding sleeve 511.
[0049] When using the rotating mechanism of this invention to detect foreign objects inside the bottle 600, the clamping power unit 501 first activates, pushing the transmission rod 502 to extend, which in turn drives the connecting part 503 and the rotating part 504 to rotate, thus opening the clamping part 505. The bottle 600 to be tested is then placed between the two clamping parts 505. The clamping power unit 501 then retracts the transmission rod 502, thereby completing the clamping of the clamping part 505. During operation, the power end of the rotating power unit 200 rotates. The passive pulley 507 is driven to rotate by the belt assembly. The passive pulley 507 drives the sliding sleeve 511 to rotate synchronously, which in turn drives the bottle 600 to be tested in the clamping unit to rotate synchronously. If it is necessary to adjust the tilt angle of the bottle 600 to be tested, the angle adjustment power unit 100 is activated, acting on one end of the rotating plate 300, so that the rotating plate 300 rotates around its connection point with the support 400, thereby realizing the synchronous rotation of the rotating plate 300 by the spin assembly 500, thus completing the adjustment of the tilt angle of the bottle 600 to be tested.
