Description

Technical Field

[0001] This utility model relates to the field of bottle spinning technology, and in particular to a non-contact magnetic bottle spinning assembly. 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] When performing visual inspections on large-volume parenteral blood products, the bottles to be tested need to be inverted and rotated 360° around the circumference of the test bottle to ensure the accuracy of the test data. Traditionally, the bottles are held and flipped using a clamp. Rotation is typically achieved through a bottle-rubbing belt that contacts the bottle-rubbing wheels of the clamp. The movement of the bottle-rubbing belt drives the rotation of the bottle on the clamp. During this process, the bottle-rubbing belt and the bottle-rubbing wheels are in contact and move synchronously through friction. Therefore, there is a phenomenon of residue and powder falling between the bottle-rubbing belt and the bottle-rubbing wheels, which affects product quality. Furthermore, if slippage occurs between the bottle-rubbing belt and the bottle-rubbing wheels, it can easily affect the accuracy of the test results.

[0004] Existing technology discloses a residual oxygen detection device, utility model patent CN217586931U, which discloses a device including a dial wheel, a rotating shaft at the bottom of the dial wheel, a swing shaft on the outer side of the rotating shaft, a mounting base on the outer side of the swing shaft, a swing rod on one side of the swing shaft, a mounting frame on the top side of the swing rod, an emitter on the top of the mounting frame, and a receiver fixedly mounted on one side of the emitter via the mounting frame. A bottle-rubbing wheel is disposed between the dial wheel and the mounting frame. Related technologies, including the above-mentioned technical solutions, still have many problems, such as: friction between the bottle-rubbing belt and the bottle-rubbing wheel causing residue or powder to fall off, affecting product quality; slippage between the bottle-rubbing belt and the bottle-rubbing wheel affecting the detection accuracy of the product. Utility Model Content

[0005] The purpose of this invention is to provide a non-contact magnetic bottle rotating assembly to solve the technical problem in the prior art where friction between the bottle rotating structure and the bottle rubbing belt causes residue or slippage, affecting the detection accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A contactless magnetic bottle-spinning assembly, comprising:

[0008] A bracket on which a guide rail is mounted for the sliding of a rotating clamp;

[0009] The magnetic strip is mounted on the bracket and extends parallel to the guide rail.

[0010] A rotating clamp for holding a bottle to be tested includes a magnetic gear that is not in contact with a magnetic strip. Both the magnetic gear and the magnetic strip are arranged with magnetic poles of permanent magnets. When the magnetic gear moves relative to the magnetic strip, it drives the magnetic gear to rotate around its central axis.

[0011] Furthermore, the rotating clamp includes:

[0012] A fixed plate is slidably installed relative to the bracket along the guide rail;

[0013] The sliding plate, which is slidably installed relative to the fixed plate in the vertical direction, is used to load and unload the bottles to be tested and to support the bottom of the bottles to be tested;

[0014] The magnetic gears are mounted on the fixed plate in a relative rotational manner.

[0015] Furthermore, the fixing plate includes an upper fixing plate and a lower fixing plate that are fixedly installed relative to each other. The upper fixing plate is provided with a bottle bottom fixing seat for limiting the bottom of the bottle to be tested, and the sliding plate is provided with a bottle mouth fixing seat for limiting the mouth of the bottle to be tested via a support rod.

[0016] Furthermore, the upper fixed plate and the lower fixed plate are fixedly installed relative to each other by a guide rod, the slide plate is slidably installed on the guide rod, and an elastic element is installed between the bottom surface of the slide plate and the lower fixed plate. This elastic element is used to provide a preload force for the slide plate to move away from the lower fixed plate.

[0017] Furthermore, the magnetic gear is rotatably mounted relative to the slide plate via a connecting rod, the support rod is fixedly mounted relative to the connecting rod, and the connecting rod is slidably mounted relative to the slide plate.

[0018] Furthermore, the bracket includes an upper bracket plate and a lower bracket plate, which are fixedly installed relative to each other by a support column. The guide rail is installed on the upper bracket plate, and the magnetic strip is installed on the lower bracket plate.

[0019] Furthermore, the slide plate is slidably mounted between the sliding sleeve and the guide rod.

[0020] Furthermore, both the bottle mouth fixing seat and the bottle bottom fixing seat are respectively provided with contoured grooves that fit into the bottle mouth and bottle bottom of the bottle to be tested, so as to limit the two ends of the bottle to be tested.

[0021] Furthermore, the bottle bottom fixing seat is rotatably mounted relative to the upper fixing plate via a bearing seat.

[0022] Furthermore, the elastic element is a spring.

[0023] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0024] (1). In this utility model, when the magnetic gear of the rotating clamp moves synchronously with it, there is relative motion between the magnetic gear and the magnetic strip. Under the interaction of magnetic force, the magnetic gear generates a rotational motion under the action of the magnetic strip, which in turn drives the rotating clamp to hold the bottle to be tested to rotate synchronously, thereby realizing the non-contact rotational motion of the bottle to be tested. This avoids the phenomenon of belt and bottle rubbing wheel dropping residue and powder due to friction, which is common in traditional contact bottle rotating structures, thus avoiding affecting the quality of the product. At the same time, it avoids the slippage phenomenon that is easy to exist in conventional contact drive structures, thereby ensuring the normal testing operation of the bottle to be tested.

[0025] (2). This utility model achieves rapid loading and unloading of bottles to be tested and clamping and limiting by setting a rotating clamp, with the help of a sliding plate and elastic components. The operation is convenient and quick, which helps to improve the testing efficiency. Attached Figure Description

The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0040] 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.

[0041] This invention addresses the problem in existing technologies where, for visual inspection of a bottle 600, it is necessary to flip the bottle 600 upside down so that its bottom faces upwards and rotate it 360° around its circumference to complete the inspection. A common problem with traditional bottle-rotating structures is that the rotating drive mechanism drives the bottle 600 on the rotating fixture 500 to rotate via a bottle-rubbing belt that contacts the bottle-rubbing wheel. However, this type of rotation drive suffers from friction, resulting in residue and powder falling off the bottle-rubbing belt and wheel. Therefore, this invention provides a non-contact magnetic bottle-rotating assembly, the specific technical solution of which is as follows:

[0042] See appendix Figure 1-3A non-contact magnetic bottle rotating assembly includes: a bracket on which a guide rail 200 for sliding a rotating clamp 500 is mounted. It is understood that the bracket is installed on another assembly line. The guide rail 200 provides guidance for the sliding of the rotating clamp 500 because the magnetic gear 506 and the magnetic strip 700 have a non-contact engagement; therefore, the guide rail 200 is needed to guide the running path of the magnetic gear 506. Specifically, the bracket includes an upper bracket plate 100 and a lower bracket plate 400, which are relatively fixedly installed together by support columns 300. The guide rail 200 is mounted on the upper bracket plate 100. It is understood that both the upper bracket plate 100 and the lower bracket plate 400 are plate-shaped and installed parallel to each other. At least two support columns 300 are mounted perpendicular to both the upper bracket plate 100 and the lower bracket plate 400. The guide groove of the guide rail 200 is a U-shaped structure. A magnetic strip 700 is mounted on a bracket and extends parallel to the guide rail 200. The magnetic strip 700 is mounted on the lower plate 400 of the bracket. A rotating clamp 500 is used to clamp the bottle 600 to be tested and includes a magnetic gear 506 that is not in contact with the magnetic strip 700. Both the magnetic gear 506 and the magnetic strip 700 are arranged with permanent magnet poles. When the magnetic gear 506 moves relative to the magnetic strip 700, it drives the magnetic gear 506 to rotate around its central axis. It can be understood that the magnetic gear 506, through the arrangement of permanent magnet poles (such as neodymium iron boron), utilizes the properties of like poles repelling and unlike poles attracting to convert magnetic repulsion or attraction into rotational power. When the magnetic pole position of the magnetic strip 700 moves, it attracts the magnetic gear 506 to rotate synchronously, achieving non-contact transmission. It should be noted that the distance between the magnetic strip 700 and the magnetic gear 506 is required. In this paper, the magnetic strip 700... The distance between the closest end of the magnetic gear 506 and the magnetic gear 506 does not exceed 2mm. In addition, in order to ensure that each bottle 600 to be tested is within the imaging range and rotates at least once within the imaging range, the diameter of the magnetic gear 506 is related to the movement range of the magnetic strip 700. For example, if the diameter of the magnetic gear 506 is 30mm, within the 100mm straight line range of the imaging range, the circumference of one rotation of the magnetic gear 506 is C = 3.14 * 30 = 94.2mm. Since 94.2mm < 100mm, it is considered to meet the requirement of at least one rotation. At this time, under the action of magnetic attraction, the magnetic strip 700 provides a torque of at least 0.75 N·m to the rotating clamp 500 to meet the rotation requirements. The working principle between the magnetic gear 506 and the magnetic strip 700 is prior art. For details, please refer to the utility model patent with announcement number CN201256374Y.

[0043] See appendix Figure 4-6The rotating clamp 500 includes: a fixed plate, which is slidably mounted relative to the bracket along the guide rail 200. It can be understood that the power for the fixed plate to slide relative to the bracket comes from the power drive of an external machine. This can be either an upper fixed plate 501 or a lower fixed plate 505 connected to an external drive mechanism; in this structure, the lower fixed plate 505 is used. The fixed plate includes an upper fixed plate 501 and a lower fixed plate 505 that are fixedly mounted relative to each other. The upper fixed plate 501 and the lower fixed plate 505 are parallel to each other and are fixedly mounted relative to each other via a guide rod 502. The guide rail 200 is perpendicular to both the upper fixed plate 501 and the lower fixed plate 505. The upper fixing plate 501 has a self-rotating bearing mounted on its upper surface. This bearing slides and rotates within the guide rail 200. The lower fixing plate 505 is fixed to a chain by screws. The movement of the chain provides power for the linear movement of the rotating clamp 500. The upper fixing plate 501 is provided with a bottle bottom fixing seat 512 for limiting the bottom of the bottle to be tested 600. The slide plate 504 is provided with a bottle mouth fixing seat 509 for limiting the mouth of the bottle to be tested 600 via a support rod 508. Both the bottle mouth fixing seat 509 and the bottle bottom fixing seat 512 are respectively provided with contoured grooves that fit into the bottle mouth and bottom of the bottle to be tested 600 to limit the two ends of the bottle to be tested 600. The bottle bottom fixing seat 512 is rotatably mounted relative to the upper fixing plate 501 via a bearing seat 510. The support rod 508 is fixedly mounted relative to the connecting rod 507. The connecting rod 507 is rotatably mounted relative to the sliding plate 504 via a bearing, so that the bottle 600 to be tested can rotate relative to the upper fixing plate 501 and the lower fixing plate 505. The sliding plate 504 is slidably mounted relative to the fixing plate in the vertical direction, and is used to realize the loading and unloading of the bottle 600 to be tested and to support the bottom of the bottle 600 to be tested. The sliding plate 504 is slidably mounted relative to the guide rod 502 via a sliding sleeve 503. Here, the sliding sleeve 503 can be a linear bearing or other mechanical structure that helps to ensure the sliding stability between the sliding plate 504 and the guide rod 502. The slide plate 504 is slidably mounted on the guide rod 502, and an elastic element is installed between the bottom surface of the slide plate 504 and the lower fixed plate 505. This elastic element is used to provide a preload force for the slide plate 504 to move away from the lower fixed plate 505. The elastic element is a spring 511. It can be understood that the two ends of the spring 511 are respectively embedded in the grooves installed on the upper surface of the lower fixed plate 505 and the lower surface of the slide plate 504. One end of the slide plate 504 is provided with a bearing. By acting on the bearing, the slide plate 504 can move along the guide rod 502, thereby moving the slide plate 504 away from the upper fixed plate 501. The bottle to be tested 600 can be placed between the bottle bottom fixing seat 512 and the bottle mouth fixing seat 509. Then, the force on the bearing is removed. At this time, under the force of the spring 511, the bottle mouth fixing seat 509 and the bottle bottom fixing seat 512 clamp the bottle to be tested 600.The magnetic gear 506 is rotatably mounted on the fixed plate. Specifically, the magnetic gear 506 is rotatably mounted relative to the slide plate 504 via the connecting rod 507. The support rod 508 is fixedly mounted relative to the connecting rod 507, and the connecting rod 507 is slidably mounted relative to the slide plate 504.

[0044] When the contactless magnetic bottle rotating assembly disclosed in this utility model is in operation, the bearing at one end of the sliding plate 504 is activated when the bottle 600 to be tested is loaded, causing the sliding plate 504 to move away from the upper fixed plate 501. The bottle 600 to be tested is placed between the bottle bottom fixed seat 512 and the bottle mouth fixed seat 509. Under the reset force of the spring 511, the bottle mouth fixed seat 509 and the bottle bottom fixed seat 512 clamp and fix the bottle 600 to be tested. The rotating clamp 500 moves linearly along the guide rail 200 under the drive of external force. At this time, the magnetic force generated between the magnetic gear 506 and the magnetic strip 700 drives the magnetic gear 506 to rotate. The connecting rod 507 and the support rod 508, which are installed synchronously with the magnetic gear 506, also rotate, thereby driving the bottle 600 to be tested to rotate, thus realizing rotational drive in a contactless scenario.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0046] The above description is only a preferred embodiment of the present utility model and is 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.
