Description

Technical Field

[0001] The invention relates to the technical field of biological detection, and in particular to a test paper cutting device. Background Art

[0002] In the production of test strips, the test strip electrodes are printed, and there are hundreds of test strips on a printed substrate. In the final stage of test strip production, these hundreds of test strips must be cut into individual strips and bottled and stored in specified quantities, such as 25 or 50 test strips. Currently, test strips are cut by punching and rolling, and the test strips are often counted manually or with additional counting devices such as detector counting. Both manual counting and detector counting count the test strips one by one before bottling, which is inefficient, and manual counting sometimes results in errors.

[0003] Based on the above situation, it is necessary for us to design a test paper cutting device that can solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a test paper cutting device, which can quickly and accurately count while completing the test strip cutting, is convenient for subsequent bottling, and has a simple structure and is easy to use.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0007] Specifically, the whole page of test paper to be punched is a whole page of test strip arrays, the punches on the punch array are raised portions of the lower end surface of the punch seat protruding toward the mesh array, the shapes of the punches and the mesh shapes on the mesh array are both rectangles consistent with the shapes of the test strips, the size of the punches is slightly smaller than the size of the test strips, which facilitates punching out the test strips, and the size of the meshes is slightly larger than the size of the test strips, which facilitates the test strips to fall from the meshes, and each test strip corresponds to a punch above and a mesh below.

[0008] When in use, the whole page of test paper to be punched is fixedly placed on the support seat, the punch seat is pressed down, the punch is connected with the test strip and the test strip is punched off the whole page of test paper to be punched, and the washed test strip falls from the mesh to the collecting mechanism below, and the other parts of the whole page of test paper to be punched, that is, the waste, are left on the support seat, which is convenient for cleaning. Since the number of meshes corresponding to the collecting unit is known, after the whole page of test paper to be punched is completely punched, the number of test strips collected in each collecting unit is known, and when the test strips are subsequently bottled, the test strips in one collecting unit are directly bottled, that is, the required number of test strips are bottled, and there is no need to count the test strips one by one, and the bottling efficiency is high. The test paper cutting device can be manually operated or machine operated. When manually operated, a handle is installed on the upper end of the punch seat, and the handle is held by hand and pressed down to complete the punching when in use; when machine operated, the punch seat can be installed on an existing driving device such as a cylinder arm of a cylinder, and the driving device drives the punch seat to move to complete the punching.

[0009] Preferably, the whole sheet of test paper to be punched has been preliminarily punched by a punching device before being placed on the test paper cutting device, so that only a small amount of adhesion between the test strip and the printed substrate remains, and the rest is cut off by the punching device. The preliminary punching makes it easy to punch out the test strip without tearing after the whole sheet of test paper to be punched is placed on the test paper cutting device. The punching device for preliminary punching is a punching device known to those skilled in the art or commonly used in the prior art that can perform basic punching functions, such as a hydraulic punching machine, and its structure and principle are all prior art and will not be described in detail here.

[0015] As a preferred technical solution, each of the collecting grooves corresponds to a column of meshes in the grid array.

[0016] Specifically, one row of meshes corresponds to one row of test strips on the full sheet of test paper to be punched, and since the number of meshes in one row is known, the number of test strips falling into the collecting groove after punching is also known, and counting is convenient. Of course, each collecting groove may also correspond to multiple rows of meshes.

[0017] As a preferred technical solution, the collection unit is a collection chamber formed by installing a baffle on the collection mechanism.

[0018] Specifically, the baffle is installed on the collection mechanism to form a collection chamber.

[0024] Preferably, the collecting chamber is rectangular, and each collecting chamber corresponds to a column of meshes in the grid array.

[0025] Specifically, since the number of test strips dropped from each column of meshes is known, when more test strips are needed for bottling, some baffles can be removed as needed so that each collection chamber corresponds to two or more columns of meshes to obtain a larger collection chamber.

[0026] As a preferred technical solution, a fixing mechanism for fixing the full page of test paper to be punched is provided on the support seat.

[0027] Specifically, the whole page of test paper to be punched is placed at a suitable position on the support seat, that is, each test strip corresponds to a mesh hole, and the whole page of test paper to be punched is fixed on the receiving seat using a fixing mechanism to prevent the whole page of test paper to be punched from shifting during punching.

[0028] As a preferred technical solution, the fixing mechanism is a plurality of fixing pins arranged on the support base and located outside the grid array.

[0029] Specifically, a plurality of through holes are arranged on the test paper to be punched, and the positions of the through holes correspond to the positions of the fixing pins. The test paper to be punched is placed on the support seat so that each through hole is sleeved on the fixing pin, thereby fixing the test paper to be punched, which is convenient to use.

[0033] Preferably, the lower end surface of the punch seat is provided with a concave cavity for storing the magnetic strip. The position of the concave cavity corresponds to the position of the magnetic strip. When the punch seat moves downward, the magnetic strip is stored in the concave cavity.

[0034] As a preferred technical solution, the test paper slitting device further includes a positioning mechanism for positioning the punch seat, the support seat and the collecting mechanism relative to each other.

[0035] Specifically, a positioning mechanism is provided so that when the collecting mechanism is installed under the support seat, the collecting unit faces the mesh array above, and when the punch seat moves toward the support seat, the punch array faces the mesh array below, and each punch faces a mesh below.

[0052] In order to have a further understanding and recognition of the structural features and the effects achieved by the present invention, a preferred embodiment and accompanying drawings are used for detailed description as follows:

[0053] Embodiment 1

[0054] A test paper cutting device, such as Figures 1 to 3As shown, it includes a punch seat 1, a support seat 2 and a collecting mechanism 3. The support seat 2 is arranged below the punch seat 1. The punch seat 1 is provided with a punch array 11 facing the support seat 2. The support seat 2 is provided with a grid array 21 that forms a punching and cutting match with the punch array 11. Each punch 12 in the punch array 11 corresponds to the position of the test strip 41 on the full-sheet test paper 4 to be punched. The collecting mechanism 3 is arranged below the support seat 2. A plurality of collecting units 31 are arranged in the collecting mechanism 3. Each collecting unit 31 corresponds to a certain number of meshes 22 in the grid array 21.

[0055] like Figures 4 to 6 As shown, the whole page of test paper 4 to be punched is a whole page of test strip arrays. The shapes of the punches 12 on the punch array 11 and the shapes of the meshes 22 on the grid array 21 are all rectangular shapes consistent with the test strip shape 41. The size of the punch 12 is slightly smaller than that of the test strip 41, so that the test strip 41 can be punched out easily. The size of the mesh 22 is slightly larger than that of the test strip 41, so that the test strip 41 can be dropped out easily from the mesh 22. Each test strip 41 corresponds to a punch 12 above and a mesh 22 below. The whole page of test paper 4 to be punched has been preliminarily punched by the punching equipment before being placed in the test paper slitting device, so that only a small amount of adhesion between the test strip 41 and the printed substrate 42 remains, and the rest is punched and cut off by the punching equipment. After the preliminary punching is performed to place the whole page of test paper 4 to be punched in the test paper 41 slitting device, the test strip 41 can be punched out easily without tearing. The punching equipment for preliminary punching is a punching equipment known to those skilled in the art or commonly used in the prior art that can perform basic punching functions, such as a hydraulic punching machine (the model may be the CX108K hydraulic punching equipment produced by Dongguan Kexinmeng Machinery Co., Ltd.), the structure and principle of which are all prior art and will not be repeated here.

[0056] In this embodiment, if Figure 7 As shown, the collecting unit 31 is a collecting groove opened on the collecting mechanism 3. The collecting groove is formed on the bottom plate of the collecting mechanism 3 and is a semi-through groove.

[0057] In other embodiments, Figure 8 As shown, the bottom plate of the collecting groove is an inclined structure, and the collecting groove gradually inclines downward from the closed end to the open end. The collecting groove with an inclined structure facilitates the test strip to slide out.

[0058] In this embodiment, each collecting groove corresponds to a row of mesh holes 22 in the grid array 21. In other embodiments, each collecting groove may also correspond to multiple rows of mesh holes 22.

[0059] In this embodiment, a fixing mechanism 23 for fixing the whole page of test paper 4 to be punched is provided on the support seat 2. The fixing mechanism 23 is a plurality of fixing pins arranged on the support seat 2 and located outside the grid array 21. A plurality of through holes 43 are provided on the whole page of test paper 4 to be punched, and the positions of the through holes 43 correspond to the positions of the fixing pins. The whole page of test paper 4 to be punched is placed on the support seat 2 so that each through hole 43 is sleeved on the fixing pin to complete the fixation of the whole page of test paper 4 to be punched. A blind hole (not shown) for accommodating the fixing pin is provided on the lower end surface of the punch seat 1. The position of the blind hole corresponds to the position of the fixing pin, and the upper end of the fixing pin is hidden in the blind hole when the punch seat 1 moves downward.

[0060] In this embodiment, the test paper slitting device further includes a positioning mechanism for positioning the punch seat 1, the support seat 2 and the collecting mechanism 3 relative to each other. The positioning mechanism is provided so that when the collecting mechanism 3 is installed below the support seat 2, the collecting unit 31 faces the mesh array 21 above, and when the punch seat 1 moves toward the support seat 2, the punch array 11 faces the mesh array 21 below, and each punch 12 faces a mesh 22 below.

[0061] In this embodiment, the positioning mechanism includes a positioning rod 33, a first positioning hole 24, and a second positioning hole 13. A plurality of positioning rods 33 are fixedly arranged on the collecting mechanism 3. A first positioning hole 24 matching with the positioning rod 33 is provided on the support seat 2. A second positioning hole 13 matching with the positioning rod 33 is provided on the punch seat 1. The plurality of positioning rods 33 can pass through the first positioning hole 24 and the second positioning hole 13 in sequence. When the punch seat 1 slides to the support seat 2, all the punches 12 on the punch seat 1 are aligned with the mesh 22 on the support seat 2.

[0062] When the test paper slitting device is used, the collecting mechanism 3 is located below the support seat 2, the positioning rod 33 passes through the first positioning hole 24, and the whole-page test paper 4 to be punched is placed on the support seat 2. At this time, the through holes 43 on the whole-page test paper 4 to be punched are all sleeved on the fixing pins on the support seat 2, and the punch seat 1 is pressed downward, and the positioning rod 33 passes through the second positioning hole 13 until the punch array 11 contacts the whole-page test paper 4 to be punched, and the punch seat 1 is continued to be pressed downward. The test strip 41 on the whole-page test paper 4 to be punched will be separated from the printed substrate 42 under the pressure of the punch 12. The test strip 41 is punched out, and the printed substrate 42 remains on the support seat 2. The punching of the test strip 41 is completed. The punched test strip 41 will pass through the mesh 22 on the support seat 2 and fall into the collection unit 31 below. The collection unit 31 of this embodiment is a collection groove. A row of meshes 22 corresponds to a row of test strips 41 on the full-page test paper 4 to be punched. Since the number of a row of meshes 22 is known, the number of test strips 41 that fall into the collection groove after punching is known, and there is no need to use traditional manual single counting or detector counting, which is convenient for counting. The collection groove is a semi-through groove. When the collection mechanism 3 is separated from the support seat 2, it is convenient to take out the test strips 42 in the collection groove and bottle them. The test strips in one collection groove are directly bottled, and the required number of test strips are bottled.

[0063] In this embodiment, the number of test strips 41 in each column on the test paper 4 to be punched is 25, the number of punches 12 in each column on the punch array 11 is 25, and the number of mesh holes 22 in each column on the grid array 21 is also 25. One collecting groove corresponds to one column of mesh holes 22. After punching, all 25 test strips 41 in one column fall into one collecting groove. The bottling of the specified number of 25 test strips can be completed by directly taking out the 25 test strips in one collecting groove and storing them all in one bottle.

[0067] In this embodiment, the baffle 32 is detachably mounted on the collection mechanism 3. The bottom plate of the collection mechanism 3 is provided with a mounting hole (not shown in the figure), and a latch (not shown in the figure) matching the mounting hole is provided at the lower edge of the baffle 32, and the baffle 32 is detachably mounted at the mounting hole. The baffle 32 is detachable, and a suitable number of baffles 32 can be installed according to demand to obtain a collection cavity of a desired size to correspond to a desired number of mesh holes 22, so that each collection cavity collects a desired number of test strips 41.

[0068] In other embodiments, the bottom plate of the collection chamber is an inclined structure, and the collection chamber with an inclined structure facilitates the test strip to slide out.

[0069] In this embodiment, the collecting cavity is rectangular, and each collecting cavity corresponds to a certain number of meshes 22 in the grid array 21. Preferably, the collecting cavity is rectangular, and each collecting cavity corresponds to a row of meshes 22 in the grid array 21.

[0070] When the test paper cutting device is used to punch out the test strips, the punched test strips 41 will pass through the mesh holes 22 on the support seat 2 and fall into the collecting unit 31 below. The collecting unit 31 of this embodiment is a collecting cavity, and one mesh hole 22 corresponds to one test strip 41 on the entire test paper 4 to be punched out. Since the number of mesh holes 22 corresponding to the collecting cavity is known, the number of test strips 41 that fall into the collecting cavity after punching is also known.

[0071] In this embodiment, the number of test strips 41 in each column on the test paper 4 to be punched is 25, the number of punches 12 in each column on the punch array 11 is 25, and the number of mesh holes 22 in each column on the grid array 21 is also 25. One collection cavity corresponds to one column of mesh holes 22. After punching, all 25 test strips 41 in one column fall into one collection cavity. The 25 test strips in one collection cavity are directly taken out and put into one bottle for storage to complete the bottling of the specified number of 25 test strips. If the bottling of the specified number of 50 test strips is to be completed, one baffle is removed every other baffle before punching, so that the two adjacent collection cavities are merged into one large collection cavity. The large collection cavity corresponds to two columns of mesh holes 22. After punching, all 50 test strips 41 in two columns fall into one large collection cavity. The 50 test strips in one large collection cavity are directly taken out and put into one bottle for storage to complete the bottling of the specified number of 50 test strips.

[0074] In this embodiment, the fixing mechanism is a metal strip (not shown) and a magnetic strip (not shown). The metal strip is fixedly arranged on the support seat, and the magnetic strip can be adsorbed on the metal strip. After placing the whole page of test paper to be punched at a suitable position on the support seat, the magnetic strip is placed on the whole page of test paper to be punched at the position of the metal strip, so that the magnetic strip and the metal strip attract each other and clamp the whole page of test paper to be punched.

[0075] In this embodiment, a concave cavity (not shown) is provided on the lower end surface of the punch seat to accommodate the magnetic strip. The position of the concave cavity corresponds to the position of the magnetic strip. When the punch seat moves downward, the magnetic strip is accommodated in the concave cavity.
