The bioelectrode related to the utility model can be used for testing the concentration of glucose. In some examples, the bioelectrode may include a dextranase layer, an electrode, and a flexible substrate. In some examples, the bioelectrode may be in the shape of a flexible sheet. In some examples, the bioelectrode may have a thickness of 0.2mm (millimeters) to 0.3 mm. As an example, fig. 1 shows a bioelectrode for detecting glucose concentration.

The appearance inspection apparatus 1 of the bioelectrode according to the present invention will be described below with reference to the drawings. Fig. 2 is a perspective view schematically showing the appearance detection device 1 of the bioelectrode according to the present embodiment. Fig. 3 is a front view showing the appearance detection device 1 of the bioelectrode according to the present embodiment.

As shown in fig. 2 and 3, in some examples, the appearance detecting apparatus 1 may include a test platform 10 for carrying a plurality of bioelectrodes, an optical glass platen (not shown), a CCD camera 20, and a computer test system 30. In this case, the plurality of bioelectrodes are fixed in the test platform 10 with a predetermined range of levelness and enter the photographing area (also referred to as a test area), the CCD camera 20 photographs the plurality of bioelectrodes in the photographing area according to an instruction sent from the computer test system 30 and generates a target image, and the computer test system 30 is configured to determine whether the plurality of bioelectrodes in the target image have defects and record the numbers of the defective bioelectrodes. Therefore, the testing platform 10 can maintain good levelness, and can effectively screen defective bioelectrode and improve production detection efficiency.

As described above, in some examples, the appearance inspection apparatus 1 may include the test platform 10. The test platform 10 may be used to carry a plurality of bioelectrodes. In some examples, the levelness of the test platform 10 may be less than a first predetermined value. In some examples, the first pre-value may be less than 10 micrometers (um). In this case, the CCD camera 20 (described later) can obtain a clear target image.

Fig. 4A is a schematic diagram showing the tray 101 of the appearance detection apparatus for bioelectrode according to the present embodiment. Fig. 4B is a partially enlarged view of the tray 101 of the appearance detection device for bioelectrode according to the present embodiment.

In some examples, the test platform 10 may include a tray 101 and a stationary fixture 102 (described later). In addition, the tray 101 may be used to carry a plurality of bioelectrodes. In addition, the fixing jig 102 may be used to carry the tray 101.

In some examples, the tray 101 may have a plurality of vacuum flow channel through holes 1012 (see fig. 4A). In some examples, each bioelectrode may be disposed above at least two vacuum flow channel through holes 1012 (see fig. 4B). In this case, a negative pressure may be formed at the plurality of flow channels by communicating through the vacuum flow channel through-hole 1012, the plurality of flow channels (described later), and the vacuum suction mechanism 1021, so that the bioelectrode is sucked to the tray 101. This can maintain a good levelness. Preferably, each bioelectrode may be disposed above two vacuum flow channel through holes 1012 (i.e., there may be 2 vacuum flow channel through holes 1012 under each bioelectrode, see fig. 4B). In this case, the bioelectrode can be further kept horizontal by the two vacuum gas flow channel through-holes 1012.

In some examples, the vacuum flow channel through-holes 1012 of the tray 101 may be disposed directly above the recesses 1022 of the fixing jig 102. This can further keep the bioelectrode horizontal.

In some examples, the aperture of the vacuum gas channel through-hole 1012 may be 0.2mm (millimeters) to 0.5 mm. In some examples, the vacuum flow channel through-holes 1012 may be circular holes. In addition, the number of the plurality of vacuum flow channel through holes 1012 may be a predetermined multiple of the number of the maximum testable bioelectrode (i.e., a predetermined multiple of the test sites on the tray 101). For example, the preset multiple may be 1, 2, 3, or 4, etc. In some examples, the number of the plurality of vacuum flow channel through-holes 1012 can be 120, 136, 150, 176, 200, 240, 352, etc. Since the tray 101 has a large number of vacuum flow channel through-holes 1012 (see fig. 4A) of the bioelectrode, fig. 4B is a partially enlarged view of the tray 101 showing, as an example, the positions of two vacuum flow channel through-holes 1012 (e.g., a vacuum flow channel through-hole 1012a and a vacuum flow channel through-hole 1012B) in the tray 101, each of the vacuum flow channel through-holes 1012 being located at a position matching the position of the bioelectrode.

In some examples, tray 101 may have a plurality of protrusions 1013. (see fig. 4A) in some examples, a plurality of protrusions 1013 may be provided at an edge of the tray 101. In some examples, the height of the protrusions 1013 can be greater than the thickness of the bioelectrode. This can protect the bioelectrode. In some examples, the height of each protrusion 1013 may be the same. In some examples, the height of the protrusion 1013 may be 0.5 mm. In some examples, the plurality of protrusions 1013 of the tray 101 may be covered by an optical glass pressing plate (described later) and connected. In this case, the optical glass platen can keep the warped bioelectrode horizontal, and the plurality of protrusions 1013 can protect the bioelectrode. In some examples, the protrusions 1013 may be rectangular protrusions.

In some examples, to better describe the location of protrusion 1013, fig. 4A shows 4 protrusions 1013, and 4 protrusions 1013 may include protrusion 1013a, protrusion 1013b, protrusion 1013c, and protrusion 1013d, as an example.

In some examples, the tray 101 may have a tray number. This allows the tray 101 to be identified from the tray number. In some examples, the tray number may be presented in the form of a two-dimensional code. Thereby, the tray 101 can be easily recognized.

Fig. 5 is a schematic diagram showing a bioelectrode sequence according to the present embodiment. Fig. 6 is a schematic diagram showing a plurality of bioelectrode sequences according to the present embodiment.

As described above, the tray 101 may be used to carry a plurality of bioelectrodes. In some examples, tray 101 can include a plurality of test sites for placement of bioelectrodes (see fig. 4A), each of which can correspond to a respective vacuum flow channel through-hole 1012. In some examples, multiple test sites may be arranged in rows and columns on tray 101 to form multiple sets of test sequences 1011 (see FIG. 6). In some examples, a row may correspond to a set of test sequences 1011. In some examples, the test bits in each set of test sequences 1011 may be connected in sequence. Therefore, the bioelectrode sequence can be conveniently placed.

In some examples, to better describe the location of test sequence 1011, fig. 4A shows 8 sets of test sequences 1011, by way of example, 8 sets of test sequences 1011 may include test sequence 1011a, test sequence 1011b, test sequence 1011c, test sequence 1011d, test sequence 1011e, test sequence 1011f, test sequence 1011g, and test sequence 1011 h.

In some examples, the plurality of sets of test sequences 1011 may include 6 sets of test sequences 1011. For example, the plurality of sets of test sequences 1011 may include 6, 7, 8, 9, 10, 15, or 20 sets of test sequences 1011, or the like.

In some examples, each set of test sequences 1011 includes a plurality of test bits. In some examples, each set of test sequences 1011 may include 20 test bits. For example, each set of test sequences 1011 may include 20, 21, 22, 23, 24, or 30 test bits, etc.

In some examples, the plurality of bioelectrodes may be divided into a plurality of sets of bioelectrode sequences. In some examples, the plurality of bioelectrodes in each bioelectrode sequence may be connected in sequence. Thus, each set of bioelectrode sequences can be conveniently placed into a corresponding test sequence 1011. As an example, fig. 5 shows a schematic of a set of bioelectrode sequences, and fig. 6 shows a schematic of a plurality of sets of bioelectrode sequences. In some examples, multiple sets of bioelectrode sequences may be placed into corresponding test sequences 1011, respectively.

As described above, a plurality of test sites may be distributed in rows and columns on the tray 101, with each test site having a corresponding row number and column number at a location in the tray 101. Thereby, the bioelectrode can be positioned. In addition, the row number may be obtained based on the test sequence 1011 in which the bioelectrode is located. In addition, the column number may be obtained based on the position of the test sequence 1011 where the bioelectrode is located. For example, the column number may be an index of the position of the bioelectrode in the test sequence 1011.

For example, assuming that the tray number is A1, each group of test sequences 1011 includes 20 test bits, the test bits of the first group of test sequences 1011 can be sequentially identified as A1-101, A1-102, A1-103, A1-104, A1-105, A1-106, A1-107, A1-108, A1-109, A1-110, A1-111, A1-112, A1-113, A1-114, A1-115, A1-116, A1-117, A1-118, A1-119, A1-120, etc., the test bits of the second group of test sequences 1011 can be sequentially identified as A1-201, A1-202, A1-203, A1-204, A1-205, A1-206, etc., and so on, similar test identification sequences of other groups 1011 can also be performed.

In some examples, the color of the tray 101 may be white. In this case, the contrast of the image of the target formed by the CCD camera 20 can be enhanced, and the size and color of the bioelectrode can be advantageously recognized. Thereby, analysis and judgment of the computer test system 30 can be facilitated. In some examples, the size of the tray 101 may match the number of bioelectrodes. In some examples, the size of the tray 101 may be 210 x 240 mm. In some examples, the thickness of the tray 101 may be 15 mm. In some examples, the material of the tray 101 may be one of ABS, polycarbonate, nylon, stainless steel, polyethylene terephthalate, and polyetheretherketone.

Fig. 7 is a schematic view showing the fixture 102 of the appearance inspection apparatus for bioelectrode according to the present embodiment.

As described above, in some examples, the test platform 10 may include a stationary fixture 102. In some examples, the fixing jig 102 may have a plurality of grooves 1022 (see fig. 7). In some examples, the tray 101 may cooperate with the plurality of recesses 1022 of the fixture 102 to form a plurality of airflow channels. In some examples, multiple flow channels may be in communication with each other. In this case, the generated negative pressure can be uniformly transferred to each of the vacuum gas flow channel through-holes 1012.

In some examples, the plurality of grooves 1022 may be uniformly arranged. In this case, a uniform negative pressure can be transmitted, and the adsorption force of the adsorption bioelectrode is uniform. This makes it possible to keep the bioelectrode in a horizontal state.

In some examples, the grooves 1022 may be rectangular slots. Additionally, the depth of the grooves 1022 may be 0.5 mm. In some examples, the number and location of the grooves 1022 may match the number and location of the test sequences 1011. This can facilitate the transmission of negative pressure to the bioelectrode. In some examples, the number of the plurality of grooves 1022 can be 6, 8, 10, or 16, etc. In the embodiment shown in fig. 7, the partial grooves 1022 are located in the fixing jig 102, for example, the partial grooves 1022 may include 1022a, 1022b, 1022c, and 1022 d. In some examples, the plurality of grooves 1022 may be arranged in an array in the fixing jig 102. In this case, a uniform negative pressure can be transmitted, and the adsorption force of the adsorption bioelectrode is uniform. This makes it possible to keep the bioelectrode in a horizontal state. In some examples, the plurality of grooves 1022 and the plurality of vacuum suction mechanisms 1021 (described later) may communicate.

In some examples, the fixture 102 may include a plurality of vacuum suction mechanisms 1021. As an example, as shown in fig. 7, the number of the vacuum suction mechanisms 1021 may be plural, for example, 2, 4 or 6, in the embodiment shown in fig. 7, the number of the vacuum suction mechanisms 1021 is 4, and the vacuum suction mechanisms 1021 may include 1021a, 1021b, 1021c and 1021 d. In some examples, the plurality of vacuum suction mechanisms 1021 may be in communication with a plurality of gas flow channels. Negative pressure may be formed at the plurality of flow channels based on the plurality of vacuum suction mechanisms 1021. In some examples, the negative pressure may be transferred to the plurality of bioelectrodes through the vacuum flow channel through holes 1012 of the tray 101. In this case, the plurality of bioelectrodes are attracted to the tray 101 with negative pressure formed by the plurality of flow channels. This can maintain a good levelness. Specifically, each of the plurality of vacuum suction mechanisms 1021 may communicate with a plurality of air flow channels, and vacuum is drawn based on the vacuum suction mechanisms 1021 to form negative pressure in the plurality of air flow channels.

In some examples, the test platform 10 may also include a seal ring (not shown). In some examples, a sealing ring may be disposed between the fixing jig 102 and the tray 101 such that the fixing jig 102 and the tray 101 form a sealed cavity including a plurality of flow channels.

As described above, in some examples, the appearance detecting apparatus 1 may include an optical glass platen. An optical glass platen may be used to cover the tray 101. In some examples, the optical glass pressing plate may cover the tray 101 in such a manner as to be connected with the plurality of protrusions 1013. In this case, the optical glass platen can keep the warped bioelectrode horizontal.

In some examples, the optical glass platen may be less than 10um (microns) in levelness. This can improve the accuracy of defect detection. In some examples, the material of the optical glass platen may be a colorless and transparent optical glass. In addition, the main component of the optical glass may be silica having a high purity. In some examples, the optical glass platen may be square in shape. In some examples, the optical glass platen may have a good index of refraction. Thereby, the imaging by the CCD camera 20 can be facilitated.

As described above, in some examples, the appearance detecting device 1 may include the CCD camera 20. The CCD camera 20 may be used to photograph a plurality of bioelectrodes located in a photographing area to obtain an image of a subject. In some examples, the CCD camera 20 may be located above the shooting area. In some examples, the size and shape of the capture area may match the size and shape of the test sequence 1011. This can facilitate the acquisition of a clear target image.

In some examples, the pixels of the CCD camera 20 may be greater than the second predetermined value. In some examples, the second pre-value may be greater than 2500 ten thousand pixels. Thus, a highly accurate target image can be obtained.

As described above, in some examples, the appearance inspection apparatus 1 may include the computer test system 30. The computer test system 30 may have a plurality of standard parameters stored therein. In some examples, computer test system 30 may obtain measurement parameters based on the target image,

in some examples, computer test system 30 may generate measured parameters for the target image by analyzing the target image. In some examples, the computer testing system 30 may determine whether a defect exists in the plurality of bioelectrodes by comparing the measured parameters to the standard parameters. In some examples, the computer testing system 30 may record the number of defective bioelectrodes. In some examples, the number may include a tray number and a position number of the bioelectrode in the tray 101. In addition, the location number may include a row number and a column number of the bioelectrode. Thereby, the bioelectrode can be positioned to identify a defective bioelectrode. In some examples, the computer test system 30 may be used to control the operation of the vacuum suction mechanism 1021 to adjust the negative pressure of the plurality of flow channels. This enables adjustment of the negative pressure in the plurality of flow channels.

In some examples, the appearance inspection apparatus 1 may further include a vacuum device (not shown). The evacuation device may be used to evacuate. In some examples, the evacuation device and the vacuum suction mechanism 1021 may be in communication via a conduit.

Specifically, each vacuum suction mechanism 1021 in the plurality of vacuum suction mechanisms 1021 may be in communication with a plurality of air channels, the vacuum suction mechanism 1021 may be in communication with a vacuum pumping device, and the computer test system 30 controls the vacuum pumping device to pump vacuum. In some examples, the computer test system 30 may issue a command to cause the evacuation device to stop evacuating after the negative pressure range is reached. In this case, the vacuum suction mechanism 1021, the plurality of flow channels, and the vacuum flow channel through-hole 1012 can be maintained at a negative pressure in a certain range. This allows the bioelectrode to be attracted to the tray 101 to maintain a good level.

In some examples, computer test system 30 may compare the measured parameters to the standard parameters based on a deep learning approach to determine whether each of the plurality of bioelectrodes is defective. Therefore, the defective bioelectrode can be effectively screened and the production detection efficiency can be improved.

In some examples, the test platform 10 may further include a drive device (not shown). The driving means may be used to drive the test platform 10 such that the test platform 10 is close to the photographing area or away from the photographing area. In some examples, the drive device may include a rail and a drive motor. In addition, the guide rail may be used to guide the moving path of the test platform 10. In this case, it is advantageous to place the bioelectrode in the tray 101 or to take it out of the tray 101. This enables convenient detection.

In addition, in order to better describe the appearance inspection apparatus 1 according to the present invention, an exemplary operation of the appearance inspection apparatus 1 is described below. Specifically, the plurality of bioelectrodes are divided into a plurality of sets of bioelectrode sequences and placed in the corresponding test sequences 1011 in the tray 101 of the test platform 10, the computer test system 30 issues an instruction to cause the driving motor of the driving apparatus of the test platform 10 to drive the test platform 10 to travel along the guide rail to enter the photographing region, the CCD camera 20 located above the photographing region photographs the plurality of bioelectrodes to obtain a target image, the computer test system 30 compares the measurement parameters of the target image with the standard parameters based on a depth learning method to determine whether each of the plurality of bioelectrodes has a defect and identifies the corresponding defective bioelectrode, and then displays the test result and stores the test result in the database. In addition, the results of the related tests can be shared with the back-end process data, the subsequent processes of the defective bioelectrode are not used, and the process engineer can analyze and improve the related production process according to the corresponding defects.
