Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing equipment technology, and in particular to an automatic labeling machine for medical devices. Background Technology

[0002] In the medical device manufacturing process, many medical devices require labels on both sides to indicate important information such as product details, instructions for use, and production date. Currently, most existing labeling equipment can only perform single-sided labeling. To achieve double-sided labeling, workers typically need to manually flip the medical device before labeling the other side. This method is not only inefficient and increases labor costs, but the manual flipping process can also easily contaminate or damage the medical device, affecting product quality. Furthermore, the consistency and accuracy of manual operation are difficult to guarantee, resulting in inconsistent labeling quality. Therefore, we propose an automatic medical device labeling machine. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0025] Reference Figures 1-4 An automatic labeling machine for medical devices, including

[0026] Flipping component 2 is used to enable the flipping operation of medical devices;

[0027] Conveying assembly 1: A set of conveying assemblies 1 are fixedly installed on the left and right sides of the flipping assembly 2 to convey the medical device to be labeled to the subsequent work station.

[0028] The lifting component 3 is fixedly installed at the bottom four corners of the conveying component 1 and the flipping component 2, and is used to adjust the height of the conveying component 1 and the flipping component 2.

[0029] Labeling machine 4 is divided into a front labeling unit and a back labeling unit. The front labeling unit and the back labeling unit have similar structures. Labeling machine 4 is movably arranged above a set of conveying components 1.

[0030] This device, through the construction of a conveying component 1, a flipping component 2, and a lifting component 3, enables the automatic flipping of medical devices. After the front of the medical device is labeled, it continues to move with the conveying component 1 to the flipping component 2. The flipping component 2 clamps and fixes the device, causing it to rotate 180°, so that the back, which was originally facing down, turns up. As the next conveying component 1 continues to move forward, it facilitates the subsequent labeling of the back, reduces the tediousness of manual operation, and improves the labeling efficiency of the device.

[0031] As an optional implementation, the flipping assembly 2 includes a flipping table 201. A set of symmetrically arranged flipping frames 202 are fixedly installed on the upper end of the flipping table 201. A rotating shaft 203 is arranged through the flipping frames 202. An electric gripper 204 is fixedly installed in the middle of the rotating shaft 203. A power assembly 7 is fixedly connected to one end of the rotating shaft 203 to realize the gripping and releasing of the medical device by the electric gripper 204, complete the flipping operation of the medical device, and then place the medical device on the next conveying assembly 1 for continued conveying.

[0032] The flipping table 201 serves as a basic support structure, providing a stable mounting platform for components such as the flipping frame 202 and the rotating shaft 203. A set of symmetrically arranged flipping frames 202 not only provides stable support for the rotating shaft 203 that runs through them, but also provides guidance and limit for the rotation of the rotating shaft 203. The electric gripper 204, which is fixedly installed in the middle of the rotating shaft 203, realizes the gripping and release of medical devices through its opening and closing action. It is the execution component that directly contacts the medical devices. The power component 7 connected to one end of the rotating shaft 203 drives the rotating shaft 203 to rotate, thereby realizing the 180° flipping of the medical devices held by the electric gripper 204.

[0033] As an optional implementation, the conveying assembly 1 includes a set of symmetrically arranged mounting frames 101, with a conveyor belt 102 arranged between the mounting frames 101. A drive motor 103 is fixedly installed on one side of the mounting frame 101, and the drive motor 103 is electrically connected to the conveyor belt 102.

[0034] The efficient cooperation between the drive motor 103 and the conveyor belt 102 enables continuous and stable transport of medical devices. Compared with manual handling or intermittent transport, this significantly improves production efficiency, effectively shortens the processing cycle of medical devices in the labeling stage, meets the cycle time requirements of large-scale production, and provides strong support for enterprises to increase production capacity.

[0035] As an optional implementation, the lifting assembly 3 includes a fixed screw 301, a movable cylinder 302 is movably disposed on the outside of the fixed screw 301, the movable cylinder 302 is provided with threads inside, the fixed screw 301 and the movable cylinder 302 are connected by thread engagement, a connecting block 303 is rotatably connected to the upper end of the movable cylinder 302, and the connecting block 303 is fixedly connected to the bottom of the mounting bracket 101.

[0036] The core of the lifting component 3 utilizes threaded transmission to achieve height adjustment. The fixed screw 301 is vertically set and serves as the support shaft for the entire lifting structure. The movable cylinder 302, which is sleeved on the outside, has internal threads that mesh with the external threads on the fixed screw 301. When it is necessary to adjust the height of the conveying component 1 or the flipping component 2, the movable cylinder 302 is manually rotated. Under the action of the threaded engagement, the movable cylinder 302 moves up and down linearly along the fixed screw 301, thereby achieving the adjustment of the height of the conveying component 1 and the flipping component 2 to meet different production needs.

[0037] Preferably, the power assembly 7 includes a driven gear 701 fixedly connected to one end of the rotating shaft 203. A transmission rack 702 is meshed on one side of the driven gear 701. A set of sliding grooves 703 are provided on the left and right sides of the transmission rack 702. A set of locking blocks 704 are fixedly connected to both sides of the transmission rack 702. The locking blocks 704 cooperate with the sliding grooves 703. A connecting frame 705 is fixedly connected to one end of the transmission rack 702. A movable rod 707 is fixedly connected to the connecting frame 705. A cylinder 706 is fixedly installed at one end of the movable rod 707.

[0038] The power unit 7 converts the linear motion of the cylinder 706 into the rotational motion of the shaft 203 through a gear and rack transmission. The driven gear 701, fixed to one end of the shaft 203, meshes with the transmission rack 702. When the cylinder 706 drives the movable rod 707 to move linearly, the movable rod 707 drives the transmission rack 702 to move linearly along the slide groove 703 through the connecting frame 705. Since the tooth profiles of the driven gear 701 and the transmission rack 702 are matched, the linear motion of the rack forces the driven gear 701 to rotate around the axis of the shaft 203, thereby driving the shaft 203 and the electric gripper 204 to complete the flipping action. This high-precision control ensures that the medical device is accurately positioned during the flipping process, providing a good positioning basis for the subsequent labeling process, avoiding labeling position deviation or omissions caused by flipping angle deviation, and improving the labeling quality and consistency of the product.

[0039] Preferably, the labeling machine 4 is fixedly installed with adjusting feet 5 at the four corners of its bottom for adjusting the height of the labeling machine 4, and the bottom of the adjusting feet 5 is fixedly connected with casters 6.

[0040] By adjusting foot 5, the distance between the labeling head and the surface of the medical device can be precisely controlled within the optimal labeling range. When the thickness of the medical device changes, there is no need to replace the equipment. Simply adjust foot 5 to quickly adapt, avoiding label wrinkles or poor adhesion due to height deviation. The moving wheel 6 supports 360° omnidirectional rotation. Combined with the equipment's center of gravity design, a single person can push the labeling machine 4 to move within the workshop, significantly reducing the difficulty of handling.

[0041] In use, this invention adjusts the spacing of the conveyor belt 102 of the conveyor assembly 1, the opening and closing dimensions and clamping force of the electric gripper 204 of the flipping assembly 2, and the label parameters of the labeling machine 4 according to the specifications of the medical device to be labeled. The heights of the conveyor assembly 1 and the flipping assembly 2 are adjusted via the adjusting feet 5 of the lifting assembly 3 to match the heights of upstream and downstream equipment (such as the production line of the previous process and the packaging machine of the next process). Simultaneously, the height of the labeling machine 4 is adjusted to ensure a suitable distance between the labeling head and the surface of the medical device. After the medical device to be labeled enters the conveyor assembly 1 from the previous process and the front of the medical device is labeled, the drive motor 103 drives the conveyor belt 102 to continue running, moving the medical device along... The medical device is conveyed to the flipping assembly 2 station via a fixed trajectory. When the medical device arrives at the flipping assembly 2 station, the cylinder 706 pushes the movable rod 707, which drives the transmission rack 702 to move linearly along the slide 703. The transmission rack 702 meshes with the driven gear 701, driving the driven gear 701 to rotate, which in turn drives the rotating shaft 203 and the electric gripper 204 to rotate. The electric gripper 204 picks up the medical device, and the cylinder 706 continues to operate, causing the electric gripper 204 to complete a 180° flip of the medical device, turning the originally downward-facing back to the upward-facing back. After the flip is completed, the electric gripper 204 releases, placing the medical device on the next conveying assembly 1, and continuing to convey it forward, thus realizing the labeling work on the back of the medical device.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
