Description

Technical Field

[0001] The present application relates to the field of filter membrane identification technology, and in particular to a filter membrane identification device. Background Art

[0002] At present, filter membrane recognition devices generally use scanning recognition or ID image recognition. This recognition method has relatively high requirements on light and requires a special fill light unit for fill light, which will affect the photosensitive devices inside the instrument.

[0003] In addition, the scanning and identification device requires the scanning camera to face the barcode or QR code to read the data. In actual applications, the filter clamp with the filter membrane is a centrally symmetrical device. After the filter clamp is attached with the QR code, there is always a certain gap between the filter clamp and the limit when the sample tube is loaded, it falls onto the moving disc, and the instrument is automatically transmitted. The filter clamp can rotate at any angle in the horizontal direction. When it moves to the scanning position, the barcode is likely to have shifted, causing the scanning and identification to fail. Utility Model Content

[0004] In view of this, the present application provides a filter membrane recognition device to solve the problem that the existing recognition device is easy to affect the photosensitive device inside the instrument and the scanning is prone to errors.

[0005] The embodiment of the present application provides a filter membrane identification device, comprising: a filter membrane, a filter membrane holder provided with an electronic tag, a transmission component, a photoelectric switch, a card reader and a control unit, wherein:

[0006] The filter membrane is placed in the filter membrane holder;

[0007] The electronic tag is arranged on the upper surface of the filter membrane holder or is sealed in the filter membrane holder, and is used to store the filter membrane information;

[0008] The conveying component is used to convey the filter membrane holder to a specified position;

[0009] The photoelectric switch is used to send a position signal to the control unit when detecting that the filter membrane clamp reaches a specified position;

[0010] The control unit is used to control the transmission component to stop working and start the card reader after receiving the arrival signal from the photoelectric switch;

[0011] The card reader is used to read the electronic tag on the filter membrane holder and send the read filter membrane information to the control unit.

[0012] In one possible implementation, the filter membrane clamp includes an upper cover, a base and a filter screen. The upper cover and the base are annular. The outer wall of the upper cover is provided with an annular groove, and the inner wall of the base is provided with an annular groove. After the upper cover and the base are snap-fitted and connected, a cavity is formed in the middle. A filter screen is provided in the cavity, and a filter membrane is placed on the filter screen.

[0013] In one possible implementation, the inner diameter of the filter membrane clamp upper cover and the base is 41 mm, and the outer diameter of the filter membrane clamp upper cover and the base is 54.5 mm.

[0014] In one possible implementation, the outer shell of the filter holder is made of a light-proof material.

[0015] In one possible implementation, the filter membrane information includes one or more of a sample number, a sampling flow rate, a sampling mode, a start time, an end time, and a number of cycles.

[0016] In one possible implementation, the electronic tag is an NFC tag, and the card reader is an NFC card reader.

[0017] In one possible implementation, the transmission assembly includes: a stepper motor, a groove wheel structure and a moving turntable, the filter membrane clamp is placed on the moving turntable, and the stepper motor drives the groove wheel structure to rotate the moving turntable.

[0018] In a possible implementation, the conveying component is controlled to stop working by turning off the stepper motor.

[0019] In one possible implementation, when the filter membrane clamp reaches a specified position, a light shielding sheet connected to the filter membrane clamp blocks light from entering the photoelectric switch, thereby causing the photoelectric switch to generate an arrival signal.

[0020] In a possible implementation, when the filter membrane clamp is in a specified position, the distance between the card reader and the electronic tag on the filter membrane clamp is less than 10 cm.

[0021] The present application can avoid erroneous operation of the photoelectric switch and improve the recognition efficiency and utilization rate of the filter membrane clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0031] First, the design concept of the embodiments of the present application is briefly introduced.

[0032] At present, in order to identify the filter membrane, the code is usually sprayed directly on the outer ring of the filter membrane in plain text. The instrument cannot recognize the code and needs to be recognized by the human eye and manually input into the instrument. The existing filter membrane recognition system uses ID image recognition, which has high requirements for light and requires a fill light device during the recognition process. Generally, the fill light device should be directly facing the filter membrane clamp. The long fill light process may affect the detection of the internal photoelectric switch, causing the photoelectric switch to malfunction; and it is easy to fail in scanning.

[0033] In addition, ID image recognition requires characters to be engraved on the filter holder. Due to the limited size of the filter holder, the information that can be engraved is also limited, including only basic information such as the sample number. Moreover, the information engraved on the filter holder cannot be changed, which will reduce the recycling efficiency of the filter holder.

[0034] In order to solve the above technical problems, the present application proposes a filter membrane identification device, which adopts NFC identification method, does not generate light, and will not cause malfunction of the photoelectric switch; it can also eliminate the phenomenon of unrecognition caused by the characters and the recognition module not being strictly aligned, thereby improving the recognition efficiency of the filter membrane clamp; by adopting electronic tags, more filter membrane information can be set and it is convenient to erase and rewrite, thereby improving the use efficiency of the filter membrane clamp.

[0035] After introducing the application scenarios and design concepts of the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described below.

[0036] like Figure 1 As shown, the embodiment of the present application provides a filter membrane identification device, comprising: a filter membrane ( Figure 1 ), a filter membrane holder 101 with an electronic tag, a transmission component 102, a photoelectric switch 103, a card reader 104 and a control unit 105 are provided, wherein the filter membrane is placed in the filter membrane holder 101; the electronic tag is provided on the upper surface of the filter membrane holder 101 or is sealed in the filter membrane holder 101 for storing the filter membrane information; the transmission component 102 is used to transmit the filter membrane holder 101 to a specified position; the photoelectric switch 103 is used to send an in-position signal to the control unit 105 when detecting that the filter membrane holder 101 has arrived at the specified position; the control unit 105 is used to control the transmission component 102 to stop working and start the card reader 104 after receiving the in-position signal from the photoelectric switch 103; the card reader 104 is used to read the electronic tag on the filter membrane holder 101 and send the read filter membrane information to the control unit 105.

[0037] The photoelectric switch in the filter membrane identification device provided by the present application needs to work under lightless conditions. The photoelectric switch is combined with the NFC reading method to avoid malfunction of the photoelectric switch. The filter membrane clip is equipped with an electronic tag, which can be written with more information to enable the instrument to set the sampling parameters in more detail; the electronic tag can be erased and reused, avoiding the waste of materials caused by using the filter membrane clip only once, and improving the utilization rate of the filter membrane clip.

[0038] like Figure 2 As shown, the filter membrane clamp 101 includes an upper cover 106, a base 107 and a filter screen 108. The upper cover 106 and the base 107 are annular. The outer wall of the upper cover 106 is provided with an annular groove, and the inner wall of the base 107 is provided with an annular groove. After the upper cover 106 and the base 107 are snap-fitted and connected, a cavity is formed in the middle, and a filter screen 108 is provided in the cavity, and a filter membrane 109 is placed on the filter screen 108.

[0039] Preferably, the inner diameter of the upper cover 106 and the base 107 of the filter membrane holder 101 is 41 mm, and the outer diameter of the upper cover 106 and the base 107 of the filter membrane holder 101 is 54.5 mm. However, the embodiment of the present application does not limit the specific size of the upper cover and the base of the filter membrane holder 101, and those skilled in the art can select a filter membrane holder of a suitable size according to their needs.

[0040] Preferably, the outer shell of the filter membrane holder 101 is made of opaque material.

[0041] In some embodiments, the filter membrane information includes one or more of a sample number, a sampling flow rate, a sampling mode, a start time, an end time, and a cycle number.

[0042] Preferably, the electronic tag is an NFC tag, and the card reader 104 is an NFC card reader.

[0043] The filter membrane holder uses NFC recognition to identify the filter membrane, which greatly improves the recognition efficiency and avoids the problem of ID image recognition and scanning recognition failing due to the difficulty in strictly aligning the characters and the recognition module.

[0044] In some embodiments, the transmission assembly 102 includes: a stepper motor, a groove wheel structure and a moving turntable, the filter membrane clamp 101 is placed on the moving turntable, and the stepper motor drives the groove wheel structure to rotate the moving turntable.

[0045] In some embodiments, the conveying assembly is controlled to stop working by turning off the stepper motor.

[0046] In some embodiments, when the filter membrane clamp 101 reaches a specified position, a light shielding sheet connected to the filter membrane clamp 101 blocks light from entering the photoelectric switch 103, thereby causing the photoelectric switch 103 to generate a position signal.

[0047] In some embodiments, when the filter membrane holder 101 is at a specified position, the distance between the card reader 104 and the electronic tag on the filter membrane holder 101 is less than 10 cm.

[0048] In the embodiment of the present application, when the filter membrane holder 101 is at the specified position, the distance between the card reader 104 and the electronic tag on the filter membrane holder 101 is less than 10 cm, so the data written in the electronic tag can be read by the card reader 104, and then the card reader 104 transmits the read information to the control unit 105. The control unit 105 segments and extracts the received information to obtain parameters such as sample number, sampling flow, sampling mode, start time, end time and number of cycles for subsequent use.

[0049] In the embodiment of the present application, after the use of the filter membrane is completed, the filter membrane clamp can be opened, the filter membrane therein can be taken out and a new filter membrane can be installed, and the new filter membrane information can be written into the electronic tag to enter the next use process.
