[0076] Next, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments, but it is not a limitation of the present invention.

[0077] Embodiment 1

[0078] This embodiment relates to the bioassay strip solution-coated line production device of the present invention.

[0079] A schematic embodiment of the present invention, as Figures 1 to 3As shown in the figure, a production device for coating lines of a biological test strip solution includes a first conveying unit 110, a coating unit 120, a position marking unit 130, and a control unit 310. Among them, the first conveying unit 110 includes a reciprocating movement component, and the reciprocating movement component includes a power component, a sliding component, and a carrier component. The carrier component is arranged above the power component through the sliding component and is used to convey biological test strip sheets. The coating unit 120 is arranged above the first conveying unit 110 and is used to perform a coating process on the coating area of the biological test strip sheet with a coating solution to form at least one set of solution coating lines on the surface of the biological test strip sheet. Each set of solution coating lines includes at least one solution coating line. The position marking unit 130 is arranged above the first conveying unit 110 and is located upstream or downstream of the coating unit 120, and is used to perform a position marking process on the coating area of the biological test strip sheet with a colored solution to form at least one set of position marking signal lines on the surface of the biological test strip sheet. Each set of position marking signal lines includes at least one front-end position marking signal line and at least one rear-end position marking signal line. A set of solution coating lines is arranged between the front-end position marking signal line and the rear-end position marking signal line. The control unit 310 is respectively connected to the first conveying unit 110, the coating unit 120, and the position marking unit 130, and is used to control the first conveying unit 110, the coating unit 120, and the position marking unit 130 respectively.

[0080] Among them, the coating process is carried out after the position marking process, or the coating process is carried out simultaneously with the position marking process.

[0081] In subsequent cutting processes (such as cutting process, chopping process, dividing process), the biological test strip sheet can be operated according to the position marking signal lines, and then the biological test strip sheet is cut into several biological test strips.

[0082] In the present invention, several sets of solution coating lines can be formed on the biological test strip sheet, and the several sets of solution coating lines are arranged at intervals along the length direction of the biological test strip sheet.

[0083] In the present invention, each set of solution coating lines can include several solution coating lines, and the several solution coating lines are arranged at intervals along the width direction of the biological test strip sheet.

[0084] In the present invention, the colored solution is a solution with a preset color.

[0085] In the present invention, several sets of position marking signal lines can be formed on the biological test strip sheet. The several sets of position marking signal lines are arranged at intervals along the length direction of the biological test strip sheet.

[0086] The number of sets of position marking signal lines matches the number of sets of solution coating lines. Generally, the number of sets of position marking signal lines is equal to the number of sets of solution coating lines.

[0087] In the present invention, the position marking signal line can be a line segment or a discontinuous pattern (such as dots, line segments). That is, as long as a shape capable of distinguishing intervals is formed.

[0088] In the present invention, each group of position marking signal lines can include a plurality of front-end position marking signal lines and a plurality of rear-end marking signals. Among them, the plurality of front-end position marking signal lines can be arranged in an array, such as one column with multiple rows, one row with multiple columns, or multiple rows and multiple columns; the plurality of rear-end position marking signal lines can be arranged in an array, such as one column with multiple rows, one row with multiple columns, or multiple rows and multiple columns.

[0089] In the present invention, in the same group of position marking signal lines, the number of front-end position marking signal lines and the number of rear-end position marking signal lines can be the same or different.

[0090] In the present invention, in the same group of position marking signal lines, the shape of the front-end position marking signal lines and the shape of the rear-end position marking signal lines can be the same or different.

[0091] In the present invention, in the same group of position marking signal lines, the size of the front-end position marking signal lines and the size of the rear-end position marking signal lines can be the same or different.

[0092] In the present invention, there can be an interval or no interval between adjacent two groups of position marking signal lines.

[0093] When there is an interval between adjacent two groups of position marking signal lines, the rear-end position marking signal lines of the previous group of position marking signal lines do not coincide with the front-end position marking signal lines of the next group of position marking signal lines. In the slitting process, waste is generated after slitting the biological test strip sheet.

[0094] In the same group of position marking signal lines, there is a first interval between the front-end position marking signal lines and the rear-end position marking signal lines; in adjacent two groups of position marking signal lines, there is a second interval between the rear-end position marking signal lines of the previous group of position marking signal lines and the front-end position marking signal lines of the next group of position marking signal lines. Generally, the second interval is smaller than the first interval.

[0095] When there is no interval between adjacent two groups of position marking signal lines, the rear-end position marking signal lines of the previous group of position marking signal lines coincide with the front-end position marking signal lines of the next group of position marking signal lines. In the slitting process, no waste is generated after slitting the biological test strip sheet.

[0096] In the present invention, the first conveying unit 110 can perform unidirectional conveying or bidirectional conveying.

[0097] When the first conveying unit 110 performs unidirectional conveying, the position marking unit 130 is arranged upstream or downstream of the coating unit 120, and the process is: position marking unit 130 → coating unit 120, or, coating unit 120 → position marking unit 130;

[0098] When the first conveying unit 110 performs bidirectional conveying, the position marking unit 130 is arranged upstream of the coating unit 120, and the process is: coating unit 120 → position marking unit 130.

[0099] In the present invention, the position marking function and the coating function are integrated, eliminating the need to separately set up a dedicated position marking unit 130, reducing the floor area of the equipment and lowering the equipment cost.

[0100] In the present invention, the first conveying unit 110 includes, but is not limited to, a reciprocating moving platform, a belt conveying moving platform, a rotating shaft type film material conveying platform, a roll type conveying platform, etc.

[0101] In the present invention, the coating unit 120 includes, but is not limited to, a gold spraying coating structure.

[0102] In the present invention, the position marking unit 130 includes, but is not limited to, an inkjet marking structure.

[0103] In the present invention, the control unit 310 includes, but is not limited to, a PLC, a single-chip microcomputer, etc.

[0104] The technical effects of the present invention are as follows:

[0105] 1) Integrating the position marking unit and the coating unit, eliminating the need to separately set up an additional marking structure, reducing the floor area of the equipment and lowering the equipment cost;

[0106] 2) Arranging the position marking unit upstream of the coating unit, the coating process can be carried out according to the position marking signal lines formed by the position marking unit on the biological test strip sheet material, avoiding problems such as repeated coating or missed coating;

[0107] 3) Utilizing the position marking signal lines formed by the position marking unit on the biological test strip sheet material facilitates the subsequent cutting process of the biological test strip sheet material, improving the yield rate of the biological test strip, enhancing production efficiency, and reducing production costs.

[0108] Embodiment 2

[0109] This embodiment is a variant embodiment of Embodiment 1.

[0110] As Figures 1 to 3As shown in the figure, the biological test strip solution-coated line production device further includes a second conveying unit 210, a third conveying unit 220, a first deviation rectifying unit 230, and a second deviation rectifying unit 240. Among them, the second conveying unit 210 is arranged downstream of the first conveying unit 110 and is connected to the control unit 310 for conveying the biological test strip sheet after the coating process and the position marking process; the third conveying unit 220 is arranged downstream of the first conveying unit 110, is symmetrically arranged with the second conveying unit 210, and is connected to the control unit 310 for conveying the biological test strip sheet after the coating process and the position marking process; the first deviation rectifying unit 230 is arranged downstream of the second conveying unit 210 and is connected to the control unit 310 for detecting the position marking signal line of the biological test strip sheet and forming a first deviation rectifying signal; the second deviation rectifying unit 240 is arranged downstream of the third conveying unit 220, is arranged in parallel with the first deviation rectifying unit 230, and is connected to the control unit 310 for detecting the position marking signal line of the biological test strip sheet and forming a second deviation rectifying signal.

[0111] Among them, in the case where the first deviation rectifying signal and the second deviation rectifying signal are not synchronized, the control unit 310 adjusts the conveying speed of the second conveying unit 210 and / or the third conveying unit 220 to synchronize the first deviation rectifying signal and the second deviation rectifying signal.

[0112] In this embodiment, the second conveying unit 210 and the third conveying unit 220 convey the same biological test strip sheet at the same time. That is, a part of the biological test strip sheet is located on the second conveying unit 210, and another part of the biological test strip sheet is located on the third conveying unit 220.

[0113] The second deviation rectifying unit 240 being arranged in parallel with the first deviation rectifying unit 230 means that the second deviation rectifying unit 240 and the first deviation rectifying unit 230 are symmetrically arranged horizontally and parallel to each other.

[0114] When the position of the biological test strip sheet is normal, the same position marking signal line of the biological test strip sheet can be recognized by the first deviation rectifying unit 230 and the second deviation rectifying unit 240 at the same time, that is, the first deviation rectifying signal and the second deviation rectifying signal are synchronized. In this case, the control unit 310 will not adjust the conveying speed of the second conveying unit 210 and the third conveying unit 220.

[0115] When the position of the biological test strip sheet is abnormal, the same position marking signal line of the biological test strip sheet cannot be recognized by the first deviation rectifying unit 230 and the second deviation rectifying unit 240 at the same time, that is, the first deviation rectifying signal and the second deviation rectifying signal are not synchronized. In this case, the control unit 310 adjusts the conveying speed of the second conveying unit 210 and the third conveying unit 220.

[0116] Generally, the non-synchronization of the first deviation rectifying signal and the second deviation rectifying signal includes:

[0117] 1) Identify the first deviation correction signal first and then identify the second deviation correction signal

[0118] In this case, the control unit 310 adjusts the conveying speed so that the conveying speed of the third conveying unit 220 is greater than that of the second conveying unit 210:

[0119] 1. Without changing the speed of the second conveying unit 210, increase the speed of the third conveying unit 220;

[0120] 2. Reduce the speed of the second conveying unit 210 and do not change the speed of the third conveying unit 220;

[0121] 3. Reduce the speed of the second conveying unit 210 and increase the speed of the third conveying unit 220.

[0122] 2) Identify the second deviation correction signal first and then identify the first deviation correction signal

[0123] In this case, the control unit 310 adjusts the conveying speed so that the conveying speed of the second conveying unit 210 is greater than that of the third conveying unit 220:

[0124] 1. Without changing the speed of the third conveying unit 220, increase the speed of the second conveying unit 210;

[0125] 2. Reduce the speed of the third conveying unit 220 and do not change the speed of the second conveying unit 210;

[0126] 3. Reduce the speed of the third conveying unit 220 and increase the speed of the second conveying unit 210.

[0127] In some of the embodiments, the second conveying unit 210 includes, but is not limited to, a roller conveying structure.

[0128] In some of the embodiments, the third conveying unit 220 includes, but is not limited to, a roller conveying structure.

[0129] In some of the embodiments, the first deviation correction unit 230 includes, but is not limited to, an optoelectronic probe.

[0130] In some of the embodiments, the second deviation correction unit 240 includes, but is not limited to, an optoelectronic probe.

[0131] Further, the biosensor solution-coated line production device further includes a cutting unit 250. The cutting unit 250 is disposed on the side of the second conveying unit 210 and the side of the third conveying unit 220, and is connected to the control unit 310, and is used to perform a cutting process on the biosensor sheet according to the position marking signal line when the first deviation correction signal is synchronized with the second deviation correction signal to form at least one biosensor.

[0132] In some of these embodiments, the cutting unit 250 includes, but is not limited to, a cutting knife structure.

[0133] The technical effects of the present invention are as follows:

[0134] 1) By using the cooperation of the second conveying unit and the third conveying unit for double-roller conveying, the position adjustment of the biosensor sheet can be realized, ensuring that the biosensor sheet is in the correct position;

[0135] 2) By using the cooperation of the first deviation correction unit and the second deviation correction unit for double-point deviation correction detection, when the biosensor sheet is in an abnormal position, the control unit adjusts the conveying speeds of the second conveying unit and the third conveying unit, thereby adjusting the position of the biosensor sheet.

[0138] As Figures 1 to 3 shown, the biosensor solution-coated line production device further includes a visual image detection unit 140 and a defective marking and discarding unit 150. The visual image detection unit 140 is disposed above the first conveying unit 110, and is located downstream of the coating unit 120, and is connected to the control unit 310, and is used to obtain the image information of the solution-coated line of the biosensor sheet after the coating process and transmit it to the control unit 310 for the control unit 310 to determine whether the solution-coated line is qualified; the defective marking and discarding unit 150 is disposed above the first conveying unit 110, and is located upstream or downstream of the coating unit 120, and is connected to the control unit 310, and is used to perform a defective marking and discarding process on the unqualified solution-coated line with a colored solution to form a discarded signal line at the defective position for human eye recognition or visual system detection.

[0139] In this embodiment, to avoid subsequent manual identification of whether the coated line is qualified, the coated area after the coating process is detected by the cooperation of the visual image detection unit 140 and the control unit 310, so as to achieve automatic judgment, reduce manual participation, and greatly improve production efficiency. In addition, the defective marking and scrapping unit 150 performs a defective marking and scrapping process on the solution-coated lines with unqualified solution-coated lines, which is convenient for subsequent distinction between the biosensors with qualified solution-coated lines and those with unqualified solution-coated lines, and improves production efficiency.

[0140] In some embodiments thereof, the visual image detection unit 140 includes, but is not limited to, a visual acquisition structure, such as an image sensor, a camera, a video camera, etc.

[0141] In some embodiments thereof, the visual image detection unit 140 is a linear array CCD camera.

[0142] In the present invention, the defective marking and scrapping process refers to forming at least one waste signal line on the solution-coated line with unqualified solution-coated line according to a preset program. In subsequent processes, the biosensors with unqualified solution-coated lines can be picked out according to the waste signal lines.

[0143] In the present invention, the colored solution is a solution with a preset color.

[0144] In some embodiments thereof, the waste signal line and the solution-coated line may not coincide or may coincide.

[0145] Generally, the waste signal line and the solution-coated line do not coincide.

[0146] In some embodiments thereof, the waste signal line and the position marking signal line may not coincide or may coincide.

[0147] Generally, the waste signal line and the position marking signal line do not coincide.

[0148] In the case where the waste signal line and the position marking signal line coincide, there are differences between the coincident line and the ordinary position marking signal line. For example, the size of the coincident line is different from that of the ordinary position marking signal line, such as the width of the coincident line is greater than that of the ordinary position marking signal line and / or the length of the coincident line is greater than the length of the ordinary position marking signal line.

[0149] In some embodiments thereof, the defective marking and scrapping unit 150 includes, but is not limited to, an inkjet marking structure.

[0150] The technical effects of the present invention are as follows:

[0151] 1) The visual image detection unit automatically acquires the image of the solution-coated line after coating, and the control unit makes a judgment, realizing full-automatic judgment without manual intervention, improving the judgment accuracy rate and production efficiency.

[0152] 2) The defective marking and rejection unit performs the defective marking and rejection process on the solution-coated lines with unqualified solution-coated lines, facilitating the subsequent process to remove the bioassay strips with unqualified solution-coated lines, and improving the production efficiency.

[0153] Embodiment 4

[0154] This embodiment is a variant embodiment of Embodiment 3.

[0155] Furthermore, the bioassay strip solution coating line production device further includes a position acquisition unit 160. The position acquisition unit 160 is arranged on the side of the first conveying unit 110 and is connected to the control unit 310, and is used to acquire the position information of the bioassay strip sheet and transmit it to the control unit 310 so that the control unit 310 controls the defective marking and rejection unit 150 to perform the defective marking and rejection process on the unqualified solution-coated lines with a colored solution according to the position information corresponding to the unqualified solution-coated lines to form a discarded signal line at the defective position for human eye recognition or visual system detection.

[0156] In the present invention, the working principle of the position acquisition unit 160 is as follows:

[0157] The position acquisition unit 160 acquires the conveying speed signal of the first conveying unit 110, records the position information of the bioassay strip sheet according to the conveying speed signal, and further records the position information of the coating area.

[0158] In some of these embodiments, the position acquisition unit 160 includes but is not limited to an encoder.

[0159] The technical effects of this embodiment are as follows:

[0160] 1) Using the position acquisition unit to acquire the position information of the bioassay strip sheet facilitates the control unit to combine the position information with the image information transmitted by the visual image detection unit, facilitating the quick positioning of the coating lines with unqualified solution-coated lines, and further enabling the defective marking and rejection unit to accurately mark the coating lines with unqualified solution-coated lines, improving the accuracy rate and avoiding misoperation.

[0161] Embodiment 5

[0162] This embodiment is a variant embodiment of Embodiments 3 to 4.

[0163] Further, the biological test strip solution-coated line production device further includes a verification unit 170. The verification unit 170 is disposed above the first conveying unit 110, on the side of the defect marking and discarding unit 150, and is connected to the control unit 310, and is used to perform a verification process on the biological test strip sheet after the defect marking and discarding process to determine whether the discarded signal line exists.

[0164] Wherein, in the case where the discarded signal line does not exist, the verification unit 170 gives an alarm or transmits the information that the discarded signal line does not exist to the control unit 310.

[0165] The verification unit 170 and the defect marking and discarding unit 150 can be integrally arranged or separately arranged.

[0166] In the case where the verification unit 170 and the defect marking and discarding unit 150 are separately arranged, the verification unit 170 is arranged upstream or downstream of the defect marking and discarding unit 150.

[0167] Generally, the verification unit 170 is arranged upstream of the defect marking and discarding unit 150. The purpose of arranging the verification unit 170 upstream of the defect marking and discarding unit 150 is to complete the verification process on the basis of not adjusting the conveying direction of the first conveying unit 110 after the defect marking and discarding process, thereby improving the verification efficiency.

[0168] In some of these embodiments, the verification unit 170 includes, but is not limited to, an identifier.

[0169] The technical effects of this embodiment are as follows:

[0170] 1) Using the verification unit to identify the discarded signal line facilitates the control unit to determine whether the defect marking and discarding process is completed for the solution-coated line with unqualified solution-coated lines, avoiding the situation that the biological test strip with unqualified solution-coated lines is regarded as the biological test strip with qualified solution-coated lines, and improving the yield rate.

[0177] In some embodiments, the coating unit 120 performs a coating process on the coating area of the biological test strip sheet with a coating solution to form at least one set of solution coating lines on the surface of the biological test strip sheet, including:

[0178] The coating unit 120 performs a coating process on the coating area of the biological test strip sheet with a coating solution to form a plurality of sets of solution coating lines arranged at equal intervals along the length direction of the biological test strip sheet on the surface of the biological test strip sheet.

[0179] In some embodiments, the position marking unit 130 performs a position marking process on the coating area of the biological test strip sheet with a colored solution to form at least one set of position marking signal lines on the surface of the biological test strip sheet, including:

[0181] Through the above steps, by using the position marking signal lines formed on the biological test strip sheet, it is convenient for the subsequent cutting process to cut the biological test strip sheet, improving the yield rate of the biological test strip, enhancing production efficiency, and reducing production costs.

[0182] Further, as Figure 5 shown, the production method of the biological test strip solution coating line further includes:

[0183] Step S502, the second conveying unit 210 and the third conveying unit 220 simultaneously convey the bioassay strip material after the coating process and the position marking process;

[0184] Step S504, the first rectifying unit 230 detects the position marking signal line of the bioassay strip material and forms a first rectifying signal, and the second rectifying unit 240 detects the position marking signal line of the bioassay strip material and forms a second rectifying signal;

[0185] Step S506, the control unit 310 determines whether the first rectifying signal and the second rectifying signal are synchronized;

[0186] Step S508, when the first rectifying signal and the second rectifying signal are not synchronized, the control unit 310 adjusts the conveying speed of the second conveying unit 210 and / or the third conveying unit 220 to synchronize the first rectifying signal and the second rectifying signal.

[0187] In step S506, the control unit 310 determines whether the first rectifying signal and the second rectifying signal are synchronized means whether the control unit 310 receives the first rectifying signal and the second rectifying signal simultaneously.

[0188] In step S508, the first rectifying signal and the second rectifying signal are not synchronized means that the control unit 310 does not receive the first rectifying signal and the second rectifying signal simultaneously.

[0189] In step S508, the control unit 310 adjusts the conveying speed of the second conveying unit 210 and / or the third conveying unit 220 to synchronize the first rectifying signal and the second rectifying signal, including:

[0190] Step S508a, when the control unit 310 receives the first rectifying signal first, the control unit 310 adjusts the conveying speed so that the conveying speed of the third conveying unit 220 is greater than that of the second conveying unit 210;

[0191] Step S508b, when the control unit 310 receives the second rectifying signal first, the control unit 310 adjusts the conveying speed so that the conveying speed of the second conveying unit 210 is greater than that of the third conveying unit 220.

[0192] In step S508a, the control unit 310 adjusts the conveying speed including the following situations:

[0193] 1. Without changing the speed of the second conveying unit 210, increase the speed of the third conveying unit 220;

[0194] 2. Reduce the speed of the second conveying unit 210 and do not change the speed of the third conveying unit 220;

[0195] 3. Reduce the speed of the second conveying unit 210 and increase the speed of the third conveying unit 220.

[0196] In step S508b, the control unit 310 adjusts the conveying speed including the following situations:

[0197] 1. Without changing the speed of the third conveying unit 220, increase the speed of the second conveying unit 210;

[0198] 2. Reduce the speed of the third conveying unit 220 without changing the speed of the second conveying unit 210;

[0199] 3. Reduce the speed of the third conveying unit 220 and increase the speed of the second conveying unit 210.

[0200] Furthermore, after step S506 or step S508, it further includes:

[0201] Step S510: When the first deviation correction signal is synchronized with the second deviation correction signal, the cutting unit 250 cuts the biological test strip sheet according to the position marking signal line to form at least one biological test strip.

[0202] Through the above steps, when the biological test strip sheet is in an abnormal position, the control unit adjusts the conveying speeds of the second conveying unit and the third conveying unit, thereby adjusting the position of the biological test strip sheet to ensure that the biological test strip sheet is in the correct position.

[0203] Furthermore, as Figure 6 shown, the method for producing the biological test strip solution coating line further includes:

[0204] Step S602: The visual image detection unit 140 acquires the image information of the solution coating line of the biological test strip sheet after the coating process;

[0205] Step S604: The control unit 310 determines whether the solution coating line is qualified according to the image information;

[0206] Step S606: When the solution coating line is unqualified, the defect marking and scrapping unit 150 performs a defect marking and scrapping process on the unqualified solution coating line with a colored solution to form a waste signal line at the defect position for human eye recognition or visual system detection.

[0207] Among them, step S602 is performed after step S402.

[0208] In step S604, the control unit 310 determines whether the solution coating line is qualified according to the image information:

[0209] 1) Whether the size of the solution coating line is qualified;

[0210] 2) Whether the inclination angle of the solution-coated line is qualified.

[0211] For 1), whether the size of the solution-coated line meets the preset size threshold, or whether the dimensional tolerance of the solution-coated line meets the preset tolerance threshold.

[0212] Through the above steps, the fully automatic judgment of the solution-coated line after coating is carried out using the image information, without manual intervention, improving the judgment accuracy and production efficiency; for the solution-coated line with unqualified solution-coated line, the defective marking and scrapping process is carried out, which is convenient for subsequent processes to remove the bioassay strip with unqualified solution-coated line, improving the production efficiency.

[0216] Among them, step S702 is carried out synchronously with step S602.

[0217] In step S702, the position acquisition unit 160 acquires the position information of the bioassay strip after the coating process:

[0218] The position acquisition unit 160 acquires the conveying speed signal of the first conveying unit 110, records the position information of the bioassay strip according to the conveying speed signal, and further records the position information of different groups of solution-coated lines.

[0219] Through the above steps, the position information is combined with the image information, which is convenient for quickly locating the coated line with unqualified solution-coated line, and then accurately marking the solution-coated line with unqualified solution-coated line, improving the accuracy and avoiding misoperation.

[0220] Further, as Figure 8 shown, the production method of the solution-coated line of the bioassay strip further includes:

[0221] Step S802: The verification unit 170 performs a verification process on the bioassay strip after the defective marking and scrapping process to determine whether the waste signal line exists.

[0222] Among them, step S802 is performed after step S606 or step S704.

[0223] Further, after step S802, it further includes:

[0224] Step S804, in the case where the waste signal line does not exist, the verification unit 170 gives an alarm or transmits the information that the waste signal line does not exist to the control unit 310.

[0225] Through the above steps, the waste signal line is identified, which is convenient for judging whether the defective marking process for the solution-coated line with unqualified solution-coated line is completed.

In the case where the biosensor strip is in an abnormal position, the control unit adjusts the conveying speeds of the second conveying unit and the third conveying unit, thereby adjusting the position of the biosensor strip; the visual image detection unit automatically obtains the image of the biosensor strip after coating and judges through the control unit, realizing full-automatic judgment without manual intervention, improving the judgment accuracy rate and increasing the production efficiency; the defective marking unit performs the defective marking process on the solution-coated line with unqualified solution-coated line, which is convenient for removing the biosensor strip with unqualified solution-coated line in the subsequent process, increasing the production efficiency; the position acquisition unit is used to acquire the position information of the biosensor strip, which is convenient for the control unit to combine the position information with the image information transmitted by the visual image detection unit, facilitating the rapid positioning of the unqualified coated line of the solution-coated line, and further enabling the defective marking unit to accurately mark the solution-coated line with unqualified solution-coated line, improving the accuracy rate and avoiding misoperation; the verification unit is used to identify the waste signal line, which is convenient for the control unit to judge whether the defective marking process for the solution-coated line with unqualified solution-coated line is completed, avoiding the situation that the biosensor strip with unqualified solution-coated line is regarded as the biosensor strip with qualified coated line, and improving the yield.
