Abstract
Description
Technical Field
[0001] The utility model relates to the field of blood sugar test paper production, in particular to a blood sugar test paper detection and screening mechanism. Background Art
[0002] Blood sugar self-monitoring is one of the important means of managing diabetic patients, and its importance in blood sugar control has been fully recognized. Through blood sugar monitoring, patients can clearly know whether they are in the danger zone, so as to stay away from the blood sugar danger zone, achieve treatment goals, and improve the quality of life of patients. Blood sugar test strips commonly used for blood sugar self-monitoring are used in conjunction with blood sugar detection and analysis instruments. They are common disposable diagnostic reagents and medical consumables that monitor the glucose concentration value in human capillary whole blood and venous whole blood in vitro through the changes in the chemical reaction of the coated biological enzymes.
[0003] In the preparation process of blood glucose test strips, the blood glucose test strips need to be tested and screened before bottling to remove defective products. In the existing production, after the long strip of test paper is cut into multiple individual test strips, each test strip needs to be quality tested. After the test is completed, the defective products are removed by moving the suction cup with a robotic arm. However, after the long strip of test paper is cut into multiple test strips, the test strips are still in contact with each other. If there is stacking between adjacent test strips, it will affect the results of the photo detection, and when removing defective products, it is easy to cause the adjacent test strips to shift, which is not conducive to the subsequent counting of test strips and bottling steps.

DETAILED DESCRIPTION
[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0023] See also Figures 1 - 5The present embodiment provides a blood glucose test strip detection and screening mechanism, comprising a frame 1, a cutting mechanism 2 and a supporting mechanism 3. The cutting mechanism 2 and the supporting mechanism 3 are both arranged on the frame 1. The supporting mechanism 3 is arranged on the right side of the cutting mechanism 2 and is used to receive multiple test strips output by the cutting mechanism 2. The supporting mechanism 3 comprises a supporting unit 31 and a driving mechanism 32. A plurality of the supporting units 31 are arranged in parallel front and back. The supporting unit 31 is used to place a single test strip, and the driving mechanism 32 is used to drive adjacent supporting units 31 to separate from each other.
[0024] When the utility model is used, a long strip of test paper is placed into the cutting mechanism 2, the test paper is cut into a plurality of test strips by the cutting mechanism 2, and then the test strips are received by the supporting mechanism 3, and each test strip is placed one by one on each supporting unit 31, and then the supporting units 31 are separated from each other by the driving mechanism 32, and the adjacent test strips are separated from each other, thereby reducing the risk of adjacent test strips stacking and affecting the test results, and also ensuring that when defective products are detected and removed, they will not contact adjacent test strips and cause adjacent test strips to shift, thereby facilitating the subsequent counting and bottling of qualified test strips.
[0025] See also Figure 2 , Figure 3 The driving mechanism 32 includes a screw rod 33 and a limit rod 34. The screw rod 33 is rotatably arranged in the frame 1, and the limit rod 34 is fixed in the frame 1. The plurality of support units 31 are slidably arranged on the limit rod 34 forward and backward. The screw rod 33 is provided with a plurality of thread segments 35. The support units 31 are arranged one by one on each thread segment 35 and are threadedly connected with the thread segments 35. The pitches of adjacent thread segments 35 are different from each other.
[0026] The screw rod 33 is driven to rotate by a driving device (such as a motor). Since the support unit 31 is connected to the threaded segment 35 on the screw rod 33 through a threaded structure, and under the limiting action of the limiting rod 34, the support unit 31 moves along the screw rod 33 in the front-to-back direction when the screw rod 33 rotates. At the same time, since only one support unit 31 is connected to each threaded segment 35, and the pitches of adjacent threaded segments 35 are different, the distances of the front-to-back displacements of adjacent support units 31 are different when the screw rod 33 rotates the same number of times, thereby achieving the purpose of separating adjacent support units 31. The driving mechanism 32 has a simple structure, and does not need to be equipped with a driving device (such as a cylinder) for driving the movement of each support unit 31, thereby reducing the production cost of the utility model and facilitating maintenance.
[0027] See also Figure 2 , Figure 3, several thread segments 35 on the screw 33 are symmetrically arranged before and after with respect to the center point of the screw 33, and the pitch of the thread segments 35 closer to both ends of the screw 33 is larger.
[0028] When the screw 33 rotates, several support units 31 on the screw 33 move towards the front and rear ends of the screw 33 with the central position of the screw 33 as the center of symmetry, that is, the support units 31 on the rear half of the screw 33 move towards the rear end of the screw 33, and the support units 31 on the front half of the screw 33 move towards the front end of the screw 33. Also, since the pitch of the thread segments 35 closer to both ends of the screw 33 is larger, the support units 31 closer to both ends of the screw 33 move a greater distance when the screw 33 rotates by the same angle. Thus, when the support units 31 spread from the center of the screw 33 towards the front and rear ends, the support units 31 closer to both ends of the screw 33 will not interfere with the movement of the support units 31 closer to the center of the screw 33, thereby ensuring the normal operation of the support mechanism 3 under the action of the drive mechanism 32.
[0029] See Figure 1 , Figure 4 , the cutting mechanism 2 includes an upper cutting roller 21 and a lower cutting roller 22. The upper cutting roller 21 and the lower cutting roller 22 are both rotatably arranged in the frame 1. A number of annular grooves 23 are equally spaced on the upper cutting roller 21 and the lower cutting roller 22. The distance between adjacent grooves 23 is equal to the width of the groove 23 and is equal to the width of the test strip. The upper cutting roller 21 and the lower cutting roller 22 are inserted and fitted with each other through the grooves 23.
[0030] When the long strip-shaped test paper is placed between the upper cutting roller 21 and the lower cutting roller 22, the adjacent test strip areas on the test paper are respectively aligned with the grooves 23 in the upper cutting roller 21 and the lower cutting roller 22. Thus, when the upper cutting roller 21 rotates counterclockwise and the lower cutting roller 22 rotates clockwise, the test paper entering from the left side of the cutting mechanism 2 can be cut into multiple test strips under the action of the fitting and shearing of the grooves 23 between the upper cutting roller 21 and the lower cutting roller 22 and output to the support mechanism 3 from the right side of the cutting mechanism 2. The cutting mechanism 2 has a simple structure and the advantage of relatively high cutting efficiency.
[0031] See Figure 1 , a first guide rail 11 is arranged in the frame 1. The support mechanism 3 is slidably arranged left and right on the first guide rail 11. The upper end of the support unit 31 is provided with a flat plate 36 extending to the left. A camera 4 is fixed on the frame 1 on the right side of the cutting mechanism 2.
[0032] The support unit 31 moves leftward along the first guide rail 11, causing the left end of the flat plate 36 to extend into the contact position between the upper cutting roller 21 and the lower cutting roller 22. When the test strip is output from this contact position, it can move onto the flat plate 36. Thus, by moving the support unit 31 rightward, the test strip can be moved out of the cutting mechanism 2 to below the camera 4. Meanwhile, the adjacent test strips are separated from each other by the driving mechanism 32, and then the test strip is moved to below the camera 4. The camera 4 takes a photo of the test strip and uploads it to the database for comparison to complete the detection.
[0033] See Figure 1 In the frame 1, a second guide rail 12 is provided. Three groups of third guide rails 13 are slidably arranged left and right on the second guide rail 12. A fourth guide rail 14 is slidably arranged up and down on the third guide rail 13. A suction cup assembly 15 is slidably arranged back and forth on the fourth guide rail 14.
[0034] The three groups of third guide rails 13 move left and right on the second guide rail 12 and are respectively located on the left side of the cutting mechanism 2, on the right side of the camera 4, and near the rightmost end of the second guide rail 12. The fourth guide rails 14 that slide back and forth on the three groups of third guide rails 13 and the suction cup assemblies 15 arranged on the fourth guide rails 14 are respectively used to input the long strip-shaped test strips into the cutting mechanism 2, to remove the detected defective products from the support mechanism 3, and to remove the qualified test strips from the support mechanism 3 for the next process, thereby improving the production continuity of the present utility model and the efficiency of blood glucose test strip detection and screening.
[0035] See Figure 1 On the left side of the cutting mechanism 2, a loading rack 5 is provided. The loading rack 5 is slidably arranged left and right on the first guide rail 11.
[0036] The long strip-shaped test strips transported from the previous process are carried and placed on the loading rack 5 by the suction cup assembly 15 located on the left side of the cutting mechanism 2. The loading rack 5 is driven to move rightward. A support plate 51 with the same thickness as the flat plate 36 on the support unit 31 is provided on the loading rack 5. The support plate 51 moves rightward and extends into the contact position between the upper cutting roller 21 and the lower cutting roller 22, thereby realizing the input of the test strip into the cutting mechanism 2 for slitting and improving the stability of inputting the test strip into the cutting mechanism 2.
[0037] See Figure 5 In the support unit 31, an air passage 37 runs through up and down. The lower opening of the air passage 37 is connected to a hose 38.
[0038] In the present utility model, by connecting the hose 38 to the exhaust device, after the test strip is placed on the support unit 31, a negative pressure can be formed in the air passage 37 through the exhaust device, thereby playing a role in adsorbing and fixing the test strip and improving the stability of the test strip placed on the support unit 31.
[0039] The above content described in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claims, they should all fall within the protection scope of the present utility model.
