Description

Technical Field

[0001] The utility model relates to the field of blood glucose test strip preparation, and particularly relates to a blood glucose test strip trimming mechanism. Background Art

[0002] In recent years, with the improvement of the material living standard of human beings, the prevalence rate of diabetes shows a rapid growth trend. Self-monitoring of blood glucose is one of the important means for managing diabetic patients, and its importance in blood glucose control has been fully affirmed. Through blood glucose monitoring, patients can clearly know whether they are in a dangerous area, so as to stay away from the blood glucose dangerous area, achieve the treatment goal, and improve the quality of life of patients. The blood glucose test strip commonly used for self-monitoring of blood glucose is used in combination with a blood glucose detection and analysis instrument, and is a common disposable diagnostic reagent medical consumable for in vitro monitoring of the glucose concentration value in human capillary whole blood and venous whole blood through the chemical reaction change of the coated biological enzyme.

[0003] In the preparation process of blood glucose test strips, usually multiple test strip areas are uniformly made on a large rectangular base plate, and then multiple test strips are prepared by cutting according to each test strip area. Since during the preparation process, the test strip areas are located in the middle of the base plate, during the cutting process, it is necessary to first cut off the non-test strip blank edge areas at the edge of the base plate, that is, perform the trimming operation of the blood glucose test strip. In the existing production, the trimming of the blood glucose test strip is usually to move the blood glucose test strip to two cutting stations successively by a suction cup manipulator to cut the two long sides and two wide sides of the blood glucose test strip respectively. Among them, since it is necessary to accurately place the blood glucose test strip in the two cutting stations respectively, the positioning accuracy requirements for the suction cup manipulator are relatively high. Repeatedly sucking and placing the blood glucose test strip will also affect the accuracy of its placement position. At the same time, the steps of sucking, transporting, and placing take a long time, which is not conducive to improving the production efficiency of blood glucose test strips. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a blood glucose test strip trimming mechanism. The mechanism drives the sliding plate to pass through the cutting mechanism twice, and after the first pass through the cutting mechanism, it drives the blood glucose test strip to rotate by 90 degrees, so as to realize the trimming work of the blood glucose test strip through two cuts, and achieve the purpose of avoiding the operation of repeatedly sucking and placing the blood glucose test strip, thereby improving the positioning accuracy of the blood glucose test strip.

The diameter of the long-edge cutter is smaller than the diameter of the thick section. A lifting mechanism for lifting the rotating disk is arranged between the rotating disk and the sliding plate.

[0008] In the above technical solution, preferably, the lifting mechanism includes a slider and a chute that are respectively arranged on the rotating disk and the sliding plate and are slidably connected to each other. The slider and the chute are both spiral.

Detailed Embodiment

[0023] The present utility model will be further described in detail below with reference to the drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0024] See Figures 1-7 Figures 1-7 , in this embodiment, a trimming mechanism for a blood glucose test strip includes a base 1, a sliding plate 2, and a cutting mechanism 3. The sliding plate 2 is slidably arranged on the base 1 left and right through a driving device 4. The cutting mechanism 3 is fixed on the base 1 and is located on the moving path of the sliding plate 2. A rotating disk 21 for placing the blood glucose test strip 6 is arranged on the sliding plate 2, and the rotating disk 21 is rotatably arranged on the sliding plate 2 through a first motor 22.

[0025] When the utility model is in use, in the initial state as shown in Figure 1 , first, place the blood glucose test strip 6 to be trimmed on the rotating disk 21, and then start the driving device 4 to drive the sliding plate 2 to slide on the base 1, so that the blood glucose test strip 6 moves from one side of the cutting mechanism 3 to the other side, and at the same time, the cutting mechanism 3 trims the blank positions of the two long sides 61 or the two wide sides 62 of the blood glucose test strip 6 (the shape of the blood glucose test strip 6 is as shown in Figure 7 ). Then start the first motor 22 to rotate the rotating disk 21 and the blood glucose test strip 6 by 90 degrees simultaneously (as shown in Figure 2 ). After that, start the driving device 4 to drive the sliding plate 2 to move back to its original position, and the blood glucose test strip 6 passes through the cutting mechanism 3 again. The cutting mechanism 3 trims the blood glucose test strip 6 for the second time, trimming the other two wide sides 62 or the two long sides 61 that were not trimmed in the first trimming. Thus, after the first trimming and the second trimming, the blank positions on the four peripheral edges of the blood glucose test strip 6 can be removed. Since the blood glucose test strip 6 in the utility model is always fixed on the rotating disk 21 during the trimming process, the operation of repeatedly sucking and placing the blood glucose test strip 6 is avoided. Therefore, the positioning accuracy of the blood glucose test strip 6 can be improved, thereby improving the trimming accuracy and the yield rate of the utility model. At the same time, the time required for trimming the blood glucose test strip 6 is reduced, and the production efficiency of the blood glucose test strip 6 is improved.

[0026] See Figures 1-3 Figures 1-3 , the cutting mechanism 3 includes a support seat 31 and a cutting roller 32. There are two support seats 31, which are symmetrically fixed on the front and back sides of the base 1 relative to the base 1. The two ends of the cutting roller 32 are respectively rotatably arranged in the two support seats 31. The cutting roller 32 includes a thin section 33 and two thick sections 34. The two thick sections 34 are symmetrically arranged on the front and back sides of the thin section 33. Two long side cutters 35 are arranged on the thin section 33, and one wide side cutter 36 is arranged on each of the two thick sections 34. The long side cutters 35 and the wide side cutters 36 are both annular. The diameter of the long side cutters 35 is smaller than the diameter of the thick sections 34. A lifting mechanism 5 for lifting the rotating disk 21 is arranged between the rotating disk 21 and the sliding plate 2.

[0027] In this embodiment, in the initial state, the sliding plate 2 is located on the left side of the cutting roller 32. When the blood glucose test strip 6 is placed on the rotating disk 21, the long side 61 of the blood glucose test strip 6 is in the front-back direction and the wide side 62 is in the left-right direction. The driving device 4 is used to drive the sliding plate 2 to move rightward past the cutting roller 32, and the two wide-side cutters 36 on the thick section 34 perform a rolling cutting operation on the blank edges at the two wide sides 62 of the blood glucose test strip 6. At this time, since the diameter of the long-side cutter 35 is smaller than the diameter of the thick section 34, the long-side cutter 35 does not contact the blood glucose test strip 6, so that it can be avoided that the long-side cutter 35 cuts the blood glucose test strip 6 and causes the blood glucose test strip 6 to be scrapped. The blood glucose test strip 6 moves to the right side of the cutting roller 32, and the first motor 22 is started to drive the rotating disk 21 and the blood glucose test strip 6 to rotate by ninety degrees while the rotating disk 21 is lifted by the lifting mechanism 5, so that the blood glucose test strip 6 is raised. Thus, when the driving device 4 drives the sliding plate 2 to move leftward past the cutting roller 32 in the next step, the long-side cutter 35 can contact the blood glucose test strip 6 to perform a rolling cutting operation on the blank edges at the two long sides 61 of the blood glucose test strip 6. Therefore, the present utility model realizes the rolling cutting and trimming of the blank edges of the long side 61 and the wide side 62 of the blood glucose test strip 6 through the same cutting roller 32, and has the advantage of simple structure.

[0028] See Figure 4 、 Figure 5 The lifting mechanism 5 includes a slider 51 and a chute 52 which are respectively arranged on the rotating disk 21 and the sliding plate 2 and are in sliding connection with each other. The slider 51 and the chute 52 are both spiral-shaped. The first motor 22 is fixed to the lower side edge of the sliding plate 2 through a bracket, and the output shaft of the first motor 22 is slidably inserted up and down with the rotating disk 21.

[0029] When the first motor 22 drives the rotating disk 21 to rotate, the slider 51 on the rotating disk 21 slides in the chute 52 in the sliding plate 2, thereby driving the rotating disk 21 and the blood glucose test strip 6 to move upward. When the rotating disk 21 rotates by ninety degrees, the blood glucose test strip 6 is lifted to a position where it can contact the long-side cutter 35, so as to realize the rolling cutting operation of the long-side cutter 35 on the blank edges of the two long sides 61 of the blood glucose test strip 6. This lifting mechanism 5 can cooperate with the operation of the first motor 22 and does not require an additional lifting device such as a cylinder, and has the advantage of simple structure.

[0030] See Figure 1 、 Figure 3 The driving device 4 includes a linear guide rail 41 and a second motor 42. There are two linear guide rails 41 and two second motors 42, and they are both symmetrically arranged front and back relative to the base 1. The sliding plate 2 is slidably arranged on the linear guide rail 41. The second motor 42 is fixed on the sliding plate 2 and drives the sliding plate 2 to move along the linear guide rail 41.

[0031] The sliding plate 2 is supported by two linear guide rails 41, and the sliding plate 2 is driven to move by two second motors 42, which improves the uniform force on the sliding plate 2 and thus improves the stability of the movement of the sliding plate 2.

[0032] See Figure 2 、 Figure 6 In the present utility model, a rack 44 is provided inside the linear guide rail 41, a gear 45 is provided on the output shaft of the second motor 42, and the gear 45 meshes with the rack 44 for transmission. Thus, when the second motor 42 drives the gear 45 to rotate, the sliding plate 2 can be driven to move through the meshing action between the gear 45 and the rack 44.

[0033] See Figure 1 、 Figure 4 、 Figure 5 At the middle position of the rotating disk 21, there is an upwardly convex load-bearing platform 23 in the shape of a cuboid. The shape and size of the upper side surface of the load-bearing platform 23 are adapted to the blood glucose test strip 6, and the width of the load-bearing platform 23 is smaller than the length of the thin section 33.

[0034] The blood glucose test strip 6 is supported by the convex load-bearing platform 23. After the rotating disk 21 is lifted upward by the lifting mechanism 5, the load-bearing platform 23 can support the blood glucose test strip 6 to contact the long-edge cutter 35 while the rotating disk 21 does not contact the thick section 34, avoiding the risk that the rotating disk 21 is too large in area and interferes with the thick section 34 after rising upward, resulting in the abnormal use of the present utility model.

[0035] See Figure 1 There are multiple porous vacuum suckers 24 provided inside the upper side surface of the load-bearing platform 23.

[0036] The blood glucose test strip 6 is fixed by the multiple porous vacuum suckers 24, reducing the risk that the blood glucose test strip 6 slides during the movement and contact cutting with the cutting roller 32, resulting in the scrapping of the blood glucose test strip 6 due to cutting. The multiple porous vacuum suckers 24 are connected to the vacuum pumping device through a hose, ensuring that the multiple porous vacuum suckers 24 can move left and right along with the sliding plate 2.

[0037] See Figure Figure 2 、 Figure 4 Buffer components 43 are provided on both sides of the linear guide rail 41. The buffer components 43 can be made of elastic rubber material, reducing the damage caused by the collision between the sliding plate 2 and the linear guide rail 41 when the sliding plate 2 moves to the left and right sides of the linear guide rail 41, and improving the service life of the present utility model.

[0038] The above content described in this specification is only an illustrative example of the present utility model. Those skilled in the technical field to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar ways 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, and shall fall within the protection scope of the present utility model.
