[0002] Blood glucose test strips are a type of portable medical device used to measure blood glucose levels. They are usually used with a blood glucose meter. By dropping a drop of blood on the test strip, the test strip reacts chemically with the glucose in the blood and displays the value of the blood glucose level.

[0003] Normally, two small holes (escape holes and flow channels) are opened on blood glucose test strips to improve the efficiency of blood glucose test strips in absorbing blood samples or to facilitate user operation. In the production process of blood glucose test strips, laser laser machines are usually used for small hole lasering, but when lasering some operations with smaller apertures, the edge of the hole will appear yellow, and the test strip material is prone to produce bosses after lasering (the aperture is an elliptical irregular shape), which affects the blood intake effect, damages the surface of the material, causes abnormal blood intake, and is inefficient. The second method is to use tool punching, but due to the small volume of chip removal, waste cleaning is not thorough, and it is difficult to centrally handle. Utility Model Content

[0004] The purpose of the utility model is to provide a micro-hole punching tool for a punching module. The punching module is driven to drive the punching tool and the backing plate to cooperate with each other to punch holes, thereby preventing the product from yellowing and deformation. At the same time, the material produced by punching can be embedded in the hollow tubular punching tool.

DETAILED DESCRIPTION

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] like Figure 1-Figure 4 As shown, a micro-hole punching tool for a punching die set includes a tool holder 1 that can be set on an upper template, and a pad 2 that can be set on a lower template, characterized in that: a plurality of punching tools 3 can be set on the tool holder 1, and a plurality of punching slots 201 that can correspond to the punching tools 3 are set on the pad 2;

[0025] The punching tool 3 is in the shape of a hollow tube, and is provided with a cutting edge section 301, a closing section 302, and a material storage section 303 in sequence from one end of the punching to the other end;

[0026] The inner diameter of the punching tool 3 decreases from the cutting edge section 301 to the closing section 302 and increases from the closing section 302 to the material storage section 303, and the inner diameter of the cutting edge section 301 is smaller than the inner diameter of the material storage section 303;

[0027] The cutting edge section 301 , the closing section 302 and the material storage section 303 have a smooth transition.

[0028] Specifically, in the above technical solution, the upper template and the lower template are important components of the punching module group, and the punching die is a punching technical means commonly used in the prior art, wherein the upper template can be used as a power source to drive the punching tool 3 on the tool holder 1 to be inserted into the punching slot 201 on the pad 2, and the cutting edge section 301 on the punching tool 3 and the edge of the punching slot 201 form an effective shear force to punch the product. The punching process of blood glucose test strips using the punching method can greatly increase production efficiency. Since the punching tool 3 is hollow and tubular, the waste chips punched out can be embedded in the tubular inner cavity of the cutting edge section 301 during the punching process. With the continuous punching of the punching tool 3, the waste chips can enter the closing section 302 and the material storage section 303 from the cutting edge section 301 of the punching tool 3 in turn. In this process, the waste material punched out will be squeezed and deformed due to the change in the diameter of the inner cavity of the punching tool 3, so as to ensure that the waste chips can be stably stuck in the tubular inner cavity of the cutting edge section 301 and the closing section 302. When the waste chips enter the tubular cavity of the storage section 303, since the inner diameter of the storage section 303 is larger than the inner diameter of the cutting edge section 301, that is, the inner diameter of the storage section 303 is larger than the outer diameter of the waste chips, it is convenient to discharge the waste chips in a concentrated manner.

[0029] Furthermore, in order to facilitate the daily maintenance and care of the punching tool 3, as Figure 4 As shown, the tool holder 1 includes a tool holder 101 that can be connected to the upper template, and clamping plates 102 clamped on both sides of the tool holder 101, and a contoured groove 103 that can be sleeved on the outer periphery of the punching tool 3 is provided between the tool holder 101 and the clamping plates 102, and the clamping plates 102 can be connected to the tool holder 101 by bolts 104. The tool holder 1 adopts a split structure, which can reduce the manufacturing cost and facilitate the disassembly and replacement of the punching tool 3.

[0030] Furthermore, in order to increase the stability of the punching tool 3 being fixed on the tool holder 1, as Figure 4 As shown, the outer periphery of the punching tool 3 is provided with a rubber ring 4, which can be embedded in the profiling groove 103. After the punching tool 3 and the rubber ring 4 are embedded in the profiling groove 103 between the tool holder 101 and the clamping plate 102, the tool holder 101 and the clamping plate 102 are fastened by the bolt 104. The rubber ring 4 can increase the friction between the punching tool 3 and the tool holder 101 and the clamping plate 102 by deformation, thereby preventing the punching tool 3 from sliding during the punching process. At the same time, through the characteristics of the rubber ring 4 itself, the strength of the connection between the punching tool 3 and the tool holder 1 can be ensured, and the punching tool 3 can be deformed. The rubber ring 4 can play a certain buffering role to increase the service life of the punching tool 3.

[0031] In this embodiment, in order to enable the punching tool 3 to perform centralized chip removal, a spherical protrusion 202 is provided at the bottom of the punching slot 201, and the spherical protrusion 202 can be embedded in the cutting edge section 301. After the punching tool 3 is inserted into the punching slot 201 to complete the punching action, its waste chips are blocked in the cutting edge section 301. When the punching tool 3 penetrates into the bottom of the punching slot 201, the spherical protrusion 202 can deform the waste chips and make the waste chips penetrate into the closing section 302, thereby preventing the waste chips from falling off the punching tool 3 before the next punching action and affecting the punching operation.

[0032] Furthermore, straight slot through holes 5 are provided on the tool holder 1 and the backing plate 2 to facilitate installation and position adjustment.

[0033] Furthermore, a gap is reserved between the side of the tool holder 1 connected to the upper template and the punching tool 3 to facilitate centralized processing of waste chips.

[0034] Working principle: The tool holder 1 and the pad 2 are respectively installed on the upper template and the lower template on the punching module, which can drive one end of the punching tool 3 on the tool holder 1 to be inserted into the punching slot 201 on the pad 2. The cutting edge section 301 on the punching tool 3 and the edge of the punching slot 201 form an effective shear force to punch the product. When the spherical protrusion 202 at the bottom of the punching slot 201 is pushed into the cutting edge section 301, since the punching tool 3 is a hollow tube, the waste chips punched out can be embedded in the tubular inner cavity of the cutting edge section 301. With the continuous punching of the punching tool 3, the waste chips can enter the closing section 302 and the material storage section 303 from the cutting edge section 301 of the punching tool 3 in turn, which is convenient for the centralized discharge of the waste chips and will not cause pollution to the working environment.

[0035] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
