Description

Technical Field

[0001] This utility model relates to the field of electronic tag technology, and in particular to an automatic photo detection system for RFID electronic tags on hospital blood collection tubes. Background Technology

[0002] Electronic tags, also known as radio frequency tags, transponders, or data carriers, are generally composed of coupling elements and chips. Each tag has an electronic code, and high-capacity electronic tags have user-writable storage space. They are attached to objects to identify target objects.

[0003] Chinese patent CN214150953U discloses an electronic tag testing device, including a frame and a driving device, a testing device, an unwinding device, and a rewinding device, all mounted on the frame. The driving device drives the electronic tag tape to move from the unwinding device to the rewinding device, forming a tag tape path. The testing device includes a reading device disposed on the tag tape path, used to read the chip content of the electronic tag. This invention provides an electronic tag testing device that can detect whether the chip of the electronic tag can be read normally, thus achieving chip testing of the electronic tag.

[0004] However, this technical solution is only applicable to the inspection of labels that have already met the size requirements. It is not applicable to labels that have not been cut properly, and it cannot remove the excess parts on the periphery. In other words, the cutting and inspection operations cannot be performed on the same machine, which is inconvenient and inefficient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic photo-taking and detection system for RFID electronic tags used in hospital blood collection tubes. This system uses a cutting device to cut the tags after they have been detected by the photo-taking and detection device, enabling the detection and cutting operations to be performed on the same machine. This solves the problems of inconvenience and low efficiency caused by the need for two separate operations on different machines in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic photo-taking and detection system for RFID electronic tags on hospital blood collection tubes includes: a workbench, limiting devices respectively disposed on both sides of the workbench, a photo-taking and detection device disposed on the workbench, an unwinding device disposed at one end of the workbench, a winding device disposed at the other end of the workbench, and a cutting device disposed on the side of the workbench near the winding device. The limiting devices limit the tag to ensure its smooth movement, and the cutting device cuts off any excess portion of the tag.

[0007] Preferably, the limiting device includes: a bracket fixedly connected to one side of the workbench, a limiting rod disposed in the middle of the bracket, and a plurality of limiting blocks disposed on the bracket.

[0008] Preferably, the limiting block is slidably connected to the bracket, and the limiting block is fixed by fasteners.

[0009] Preferably, the cutting device includes: a support base fixedly connected to the worktable, a rolling element disposed on the support base, and cutting assemblies disposed on both sides of the rolling element.

[0010] Preferably, the cutting assembly includes: a blade holder slidably connected to the support base and a cutting blade disposed at the bottom end of the blade holder.

[0011] Preferably, the photographic detection device includes: a photographic element disposed on the top plate of the workbench and a display panel disposed close to the side plate of the workbench.

[0012] Preferably, the unwinding device includes: a first connecting seat disposed below the support, a first driving member disposed at one end of the first connecting seat, and an unwinding roller disposed at the other end of the first connecting seat.

[0013] Preferably, the winding device includes: a second connecting seat, a second driving member disposed at one end of the second connecting seat, and a winding roller disposed at the other end of the second connecting seat.

[0014] Preferably, the take-up roller is provided with a baffle to ensure that the labels are neat.

[0015] Preferably, a light is provided on the adjacent side of the photographic lens.

[0016] The beneficial effects of this utility model are as follows: (1) By installing limiting devices on the two sides of the workbench, the label can move smoothly during unwinding and rewinding, which improves work efficiency and prevents the label surface from bending, wrinkling or cracking, thus ensuring the integrity of the label and improving the yield rate of the label.

[0017] (2) This utility model uses fasteners to adjust the distance between the two limiting blocks to adapt to different sizes of label types. That is, the limiting device can be adjusted according to the different sizes of the labels, so that the entire detection system can detect labels of different sizes. It has a wide range of applications, and the entire detection system has a simple structure, is easy to operate, and is easy to assemble and disassemble.

[0018] (3) This utility model uses a rolling component installed in a cutting device to roll and position the label, so that the cutting component will not make mistakes when cutting off the excess part of the label, further ensuring the yield of the label. The whole cutting process is simple to operate and easy to use.

[0019] In summary, this utility model has the advantages of high work efficiency, wide applicability, simple structure and convenient operation. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Example like Figures 1-5 As shown, this embodiment provides an automatic photo-taking and detection system for RFID electronic tags on hospital blood collection tubes, including: a workbench 1, limiting devices 2 respectively disposed on both sides of the workbench 1, a photo-taking and detection device 3 disposed on the workbench 1, an unwinding device 4 disposed at one end of the workbench 1, a winding device 5 disposed at the other end of the workbench 1, and a cutting device 6 disposed on the side of the workbench 1 near the winding device 5. When the result detected by the photo-taking and detection device 3 does not meet the requirements, the unwinding device 4 and the winding device 5 stop working simultaneously. At this time, the operator cuts off a string of tags on the workbench 1 and removes the unqualified tags, then connects the two parts of the tags together and places them in place, and then continues the detection operation. The limiting devices 2 limit the tags to move smoothly, and the cutting device 6 cuts off the excess parts of the tags. No manual cutting is required, the system has a high degree of automation, and improves work efficiency.

[0025] The limiting device 2 includes: a bracket 21 fixedly connected to one side of the workbench 1, a limiting rod 22 disposed in the middle of the bracket 21, and a plurality of limiting blocks 23 disposed on the bracket 21. The bracket 21 is inclined at a certain angle to the horizontal plane, so that the label can pass smoothly through the limiting device 2 and then be wound up with the winding device 5, without causing the label to be too tight, thus ensuring the integrity of the label. The limiting blocks 23 are distributed on both sides of the limiting rod 22 to ensure the consistency of label movement.

[0026] Meanwhile, the limiting block 23 is slidably connected to the bracket 21 and is fixed by fasteners 24. The bracket 21 is U-shaped and includes two horizontal bars 211 and two vertical bars 212. One end of the vertical bar 212 extends outward and is connected to the fixing block 13 of the side plate 12. The limiting block 23 is installed on the horizontal bar 211 parallel to the limiting bar 22. The distance between the two limiting blocks 23 is adapted to the width of the label to be tested. The tightness of the limiting block 23 is controlled by the fasteners 24. It is simple to operate and convenient to use. The two limiting blocks 23 can be positioned accordingly according to the size of different labels. The positioning adjustment is suitable for labels of different sizes, with a wide range of applications. The limiting device 2 can use a cylinder 25 to control the limiting block 23, with one cylinder 25 corresponding to one limiting block 23. The cylinder 25 is installed on the receiving seat 26 which is fixedly connected to the bottom of the vertical rod 212. Multiple laser displacement sensors 27 are installed on the side of the vertical rod 212, facing the side of the label. The laser displacement sensors 27 are installed in the interval between the limiting rod 22 and the horizontal rod 211. The offset of the label is adjusted in real time by the laser displacement sensors 27 and the cylinder 25, so that the label is in the optimal unwinding or rewinding position (i.e., always keeping the label flat and without wrinkles or bulges).

[0027] In this embodiment, the cutting device 6 includes: a support base 61 fixedly connected to the workbench 1, a rolling member 62 disposed on the support base 61, and a cutting assembly 63 disposed on both sides of the rolling member 62. The rolling member 62 flattens the labels sequentially to avoid wrinkles and other issues. The cutting assembly 63 is used to cut off the excess parts of the labels to ensure that the labels are qualified. The device has a simple structure and is easy to assemble and disassemble.

[0028] In this embodiment, the cutter assembly 63 includes: a cutter holder 631 slidably connected to the support base 61 and a cutter 632 disposed at the bottom end of the cutter holder 631, that is, the position of the cutter 632 is adjustable to suit different label sizes; the movement of the cutter assembly 63 can be controlled by a combination of a servo motor 64 and a ball screw mechanism 65, the lead screw 652 of the ball screw mechanism 65 is disposed at the output end of the servo motor 64, and the slider 651 on the lead screw 652 is connected to the cutter holder 631. Next, the fixing block 653 at the end of the lead screw 652 is installed on the upper surface of the support base 61, and the top of the cutter holder 631 passes through the support base 61 and is fixedly connected to the slider 651; the servo motor 64 provides power to drive the ball screw mechanism 65 to move, the lead screw 652 will rotate, and then drive the slider 651 to move horizontally. The slider 651 then drives the cutter holder 631 and the cutting blade 632 to move synchronously, realizing the adjustment of the position of the cutting blade 632, thereby ensuring the control accuracy of the cutting blade 632, making the cutting device 6 suitable for cutting labels of different sizes.

[0029] In this embodiment, the photographic detection device 3 includes: a photographic element 31 mounted on the top plate 11 of the workbench 1 and a display panel 32 mounted close to the side plate 12 of the workbench 1. The photographic element 31 takes pictures of the labels sequentially and feeds the detection results back to the display panel 32. The display panel 32 allows observation of whether the various data of the labels meet the requirements. The photographic element 31 is positioned directly facing the labels to ensure the accuracy of the label detection results. The parameters displayed on the display panel 32 generally include the dimensions and color difference. The photographic element 31 is preferably an industrial camera, typically a Hikvision SC3000 series. The photographic detection device 3 can be a combination of an industrial camera, a trigger sensor, and an image processing unit. The entire device is generally controlled by a PLC system to ensure its detection accuracy.

[0030] In this embodiment, the unwinding device 4 includes: a first connecting seat 41 disposed below the bracket 21, a first driving member 42 disposed at one end of the first connecting seat 41, and an unwinding roller 43 disposed at the other end of the first connecting seat 41. A stack of labels to be inspected is placed on the unwinding roller 43, and the stack of labels is moved to the subsequent process by the first driving member 42. The process is simple to operate.

[0031] In this embodiment, the winding device 5 includes: a second connecting seat 51, a second driving member 52 disposed at one end of the second connecting seat 51, and a winding roller 53 disposed at the other end of the second connecting seat 51. When the second driving member 52 is activated, the winding roller 53 starts to work, and rolls the intact labels after inspection into rollers in sequence. It does not require much manual operation and has a high degree of automation. The first driving member 42 and the second driving member 52 are both preferably drive motors, used to control the speed of unwinding and winding.

[0032] In this embodiment, the unwinding device 4 and the winding device 5 can be controlled by a PLC to control the tension sensor (such as Mitsubishi LX-030TD) to realize the unwinding and winding speeds. Specifically, the PLC adjusts the speed of the unwinding or winding motor through a PID algorithm to maintain the tension sensor reading, thereby controlling the speed of the unwinding roller 43 and the winding roller 53.

[0033] Of course, the take-up roller 53 is provided with a baffle 531 to ensure that the labels are neat. The function of the baffle 531 is to prevent the labels from having uneven edges during take-up, so that the labels are neater during take-up and no secondary operation is required.

[0034] In addition, an illumination lamp 33 is provided on the adjacent side of the photographing device 31, and the illumination lamp 33 is positioned directly facing the label to avoid inaccurate detection results due to unclear lighting when the label is detected by the photographing detection device 3.

[0035] Work steps Step 1: First, place the undetected label on the unwinding device 4, then pull out a section and pass it through the limiting device 2 near the end of the unwinding device 4, and then continue to unwind and convey it to the next process. Step 2: Continue unwinding until the label reaches directly below the photo detection device 3. At this time, the photo detection device 3 will detect the labels in turn. If the label passes the test, it will continue unwinding. If the label fails the test, it will be displayed on the display panel 32. At this time, you can observe which label failed the test. Step 3: After inspection, the labels will pass through the cutting device 6 and the limiting device 2 near the winding device 5 in sequence. Labels that pass inspection will pass directly through the cutting device 6, while labels that fail inspection will be repaired and cut by the cutting device 6 to make them passable, and then conveyed to the winding device 5. Step 4: The winding device 5 winds up the qualified labels in sequence.

[0036] 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.
