Abstract
Description
Technical Field
[0001] This utility model relates to the field of UDI code printing quality inspection technology, specifically a multifunctional automatic UDI code printing quality inspection instrument. Background Technology
[0002] UDI, or Unique Device Identifier, is a "digital ID card" for medical devices. It consists of a Product Identifier (DI) and a Production Identifier (PI). The DI identifies static information such as the model and specifications of the medical device, while the PI contains dynamic information such as the production batch, production date, and expiration date. UDIs are presented through carriers such as barcodes, QR codes, or RFID tags, enabling full lifecycle traceability of medical devices, covering production, distribution, and use. This system improves regulatory efficiency, facilitates rapid recall of problematic products, ensures patient safety, optimizes supply chain management, enhances product information transparency, and promotes the informatization and standardization of the medical device industry.
[0003] Quality inspection equipment is essential for UDI code printing and is a key component in ensuring UDI compliance. Employing machine vision, deep learning, and barcode verification technologies, it can inspect the quality of 1D, 2D, and RFID tags. Its core functions include verifying the existence and correctness of the UDI code, ensuring accurate reading and decoding throughout its lifecycle, and checking the completeness of product information within the encoding. It supports automatic label quality grading, generates compliance reports, and helps companies promptly identify and correct barcode issues, meeting FDA, MDR / IVDR, and other regulatory requirements, effectively improving supply chain transparency and protecting patient safety.
[0004] However, common UDI code automatic detection instruments require manual movement of the UDI code to the bottom of the detection camera and alignment with it during use. The detection area is usually quite small, and each detection requires time to align with the camera, reducing detection efficiency. Therefore, a multifunctional automatic detection instrument for UDI code printing quality is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a multifunctional automatic inspection instrument for UDI code printing quality, which has advantages such as allowing UDI codes to be placed in open areas and automatically aligning with the inspection camera, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A multifunctional automatic inspection instrument for UDI code printing quality includes an inspection platform, a support column fixedly installed on the top of the inspection platform, an inspection host fixedly installed on the top of the support column, and a UDI code positioning and feeding component provided on the top of the inspection platform.
[0008] The UDI code positioning and feeding assembly includes a rotating shaft rotatably mounted on the top of the detection platform. A rotating center plate is fixedly mounted on the top of the rotating shaft. Detection bases are fixedly mounted on both ends of the rotating center plate. A limit detection plate is placed on the top of the detection base. Two limit rods are fixedly mounted on the bottom of the limit detection plate. The top of the detection base has an installation groove that matches the limit rods.
[0009] Furthermore, a transposition motor is fixedly installed at the bottom of the detection platform, and the output shaft of the transposition motor is fixedly connected to the bottom of the rotating shaft.
[0010] Furthermore, a limit ring is fixedly installed on the top of the detection platform, and a limit groove adapted to the limit ring is opened at the bottom of the detection base.
[0011] Furthermore, a mounting plate is fixedly installed on the top of the detection host, a detection head is fixedly installed on the bottom of the detection host, and a detection lens is fixedly installed on the bottom of the detection head.
[0012] Furthermore, an annular base is fixedly installed at the bottom of the detection host. The annular base is located around the detection lens. An inclined base plate is fixedly installed at the bottom of the annular base. An illumination lamp is fixedly installed at the bottom of the inclined base plate. The illumination lamp is inclined downwards towards the center of the annular base.
[0013] Furthermore, a storage cabinet is fixedly installed at the bottom of the testing platform, and several installation partitions are fixedly installed on the inner side wall of the storage cabinet. Replacement testing trays are placed inside the storage cabinet.
[0014] Furthermore, a control computer and a printer are placed on top of the testing platform, and the control computer is electrically connected to the testing host and the printer respectively.
[0015] Furthermore, support legs are fixedly installed at the four corners of the bottom of the detection platform, and support base plates are fixedly installed at the bottom of the support legs. A motor controller is fixedly installed at the bottom of the detection platform, and the motor controller is electrically connected to the transposition motor.
[0016] Compared with the prior art, this utility model provides a multifunctional automatic inspection instrument for UDI code printing quality, which has the following beneficial effects:
[0017] This multifunctional automatic UDI code printing quality inspection instrument uses a rotating shaft at the top of the inspection platform. A rotating center plate is installed at the top of the rotating shaft. The UDI code is placed on a limiting inspection plate that is not aligned with the inspection host. The rotating shaft rotates, causing the rotating center plate to rotate, which in turn causes the two inspection bases to shift, rotating the UDI code to a position aligned with the inspection lens for inspection. This facilitates positioning and solves the problem of common automatic UDI code inspection instruments that require manual movement of the UDI code to the bottom of the inspection camera for alignment. The inspection position is usually narrow, and each inspection requires time to align with the camera's inspection position, reducing inspection efficiency. Attached Figure Description

Detailed Implementation
[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1 to 4 This embodiment of a multifunctional automatic inspection instrument for UDI code printing quality includes an inspection platform 1, a support column 2 fixedly installed on the top of the inspection platform 1, an inspection host 3 fixedly installed on the top of the support column 2, and a UDI code positioning and feeding component provided on the top of the inspection platform 1.
[0025] The UDI code positioning and feeding assembly includes a rotating shaft 4 rotatably mounted on the top of the detection platform 1. A rotating center plate 5 is fixedly mounted on the top of the rotating shaft 4. Detection bases 6 are fixedly mounted on both ends of the rotating center plate 5. A limit detection plate 7 is placed on the top of the detection base 6. Two limit rods 8 are fixedly mounted on the bottom of the limit detection plate 7. The top of the detection base 6 is provided with an installation groove 9 that matches the limit rods 8.
[0026] Specifically, the UDI code is placed on the limit detection plate 7 on one side of the detection host 3, the rotating shaft 4 rotates 180 degrees, driving the rotating center plate 5 to rotate, so that the two detection bases 6 are swapped, and the UDI code is rotated to the bottom of the detection host 3, which facilitates the quality detection of the UDI code.
[0027] Meanwhile, a transposition motor 10 is fixedly installed at the bottom of the detection platform 1, and the output shaft of the transposition motor 10 is fixedly connected to the bottom of the rotating shaft 4. The transposition motor 10 drives the rotating shaft 4 to rotate, which in turn drives the rotating center plate 5 to rotate.
[0028] The detection platform 1 has a limit ring 11 fixedly installed on its top, and the detection base 6 has a limit groove 12 adapted to the limit ring 11 on its bottom. The detection base 6 passes through the limit groove 12 to the surface of the limit ring 11, making the rotation of the detection base 6 more stable.
[0029] Please see Figure 1 and Figure 3 In this embodiment, a mounting plate 13 is fixedly installed on the top of the detection host 3, a detection head 14 is fixedly installed on the bottom of the detection host 3, and a detection lens 15 is fixedly installed on the bottom of the detection head 14.
[0030] The bottom of the detection host 3 is fixedly mounted with an annular base 16, which is located around the detection lens 15. An inclined base plate 17 is fixedly mounted on the bottom of the annular base 16, and illumination beads 18 are fixedly mounted on the bottom of the inclined base plate 17. The illumination beads 18 are tilted downwards towards the center of the annular base 16. Multiple illumination beads 18 illuminate the center, reducing the impact of light emission and shadows on the UDI code.
[0031] Please see Figure 1 and Figure 2 In this embodiment, a storage cabinet 19 is fixedly installed at the bottom of the testing platform 1. Several mounting partitions 20 are fixedly installed on the inner side wall of the storage cabinet 19. Replacement testing trays 21 are placed inside the storage cabinet 19. Replacement testing trays 21 of different specifications are connected to the testing base 6 through limiting rods 8 to adapt to different specifications of UDI codes.
[0032] The testing platform 1 has a control computer 22 and a printer 23 mounted on top of it. The control computer 22 is electrically connected to both the testing host 3 and the printer 23. The testing host 3 scans the UDI code through the testing lens 15 and transmits the scanned information to the control computer 22. The control computer 22 identifies the UDI code information. When a problem occurs with the UDI code information, the control computer 22 generates an error report, which is then printed out by the printer 23.
[0033] Secondly, support legs 24 are fixedly installed at the four corners of the bottom of the detection platform 1, and support base plates 25 are fixedly installed at the bottom of the support legs 24. A motor controller 26 is fixedly installed at the bottom of the detection platform 1, and the motor controller 26 is electrically connected to the shifting motor 10. The shifting motor 10 is a servo motor, and the motor controller 26 controls the operation of the shifting motor 10 to accurately drive the two limit detection disks 7 to shift.
[0034] The working principle of the above embodiment is as follows: the UDI code is placed on the limiting detection plate 7 on one side of the detection host 3, the rotating shaft 4 rotates 180 degrees, driving the rotating center plate 5 to rotate, so that the two detection bases 6 are swapped, and the UDI code is rotated to the bottom of the detection host 3 and aligned with the detection lens 15, so as to facilitate the quality detection of the UDI code.
[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
