DETAILED DESCRIPTION

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] The present invention discloses an automatic test paper feeding device, comprising a test paper storage device 100, an opening device 200 and a transmission device 300, wherein the test paper storage device 100 comprises a plurality of test paper storage cavities 1, and a sealing layer 2 for sealing the test paper storage cavity 1 is arranged at the opening of each test paper storage cavity 1; the opening device 200 comprises an opener; the transmission device 300 is used for changing the relative position and / or posture of the test paper storage device 100 and the opening device 200, so that the opening of each test paper storage cavity 1 is first aligned with the opener and then with the paper outlet end 4 of the automatic test paper feeding device, and the opener is used for destroying the sealing layer 2 of the test paper storage cavity 1 and leaving a hole for the test paper to pass through when aligning with the opening of any test paper storage cavity 1, so that the test paper can slide out from the hole and enter the target device through the paper outlet end 4 of the automatic test paper feeding device.

[0035] In the present invention, the test paper storage device 100 can be as follows Figure 1 As shown, it is cylindrical, and other structures can also be used, for example, all test paper storage chambers 1 are arranged side by side to form a row-shaped test paper storage device 100, or all test paper storage chambers 1 are arranged in a matrix. The test paper storage chamber 1 can be formed by punching, and aluminum foil or other materials are used as a sealing layer 2 at the opening. Each test paper storage chamber 1 can be packaged with one or more test papers according to the needs of each detection and analysis. The shape of the test paper storage chamber 1 depends on the shape of the test paper, for example, Figure 1The strip shape shown. In the present invention, the transmission device 300 can be a push rod, a motor or other structure. The transmission device 300 can be connected to the test paper storage device 100 and / or the opening device 200 in a transmission manner, so that the position and / or posture of the test paper storage device 100 and / or the opening device 200 can be changed (through translation and / or rotation, etc.), so as to achieve the purpose of aligning the opening of each test paper storage cavity 1 with the opener first and then with the paper outlet end 4 of the test paper automatic feeding device. In addition, in the present invention, the structure of the opener can be determined according to the structure of the test paper storage cavity 1 and the sealing layer 2, for example, Figure 1 As shown, the sealing layer 2 is pierced through an opening portion 3 that can reciprocate, or, when the test paper storage chamber 1 adopts a bag structure, the opener can be an automatic shearing device. In the present invention, when the opening is downward, the test paper can fall into the paper outlet 4 of the test paper automatic paper feeding device by gravity. In addition, other special devices can be provided to take out the test paper from the test paper storage chamber 1, such as an empty negative device to suck out the test paper. In the present invention, the inlet end of the target device that needs to use the test paper can be directly used as the paper outlet 4 of the test paper automatic paper feeding device, and a pipe or a connecting hole connected to the inlet end of the target device that needs to use the test paper can also be used as the paper outlet 4 of the test paper automatic paper feeding device (such as Figure 2 In addition, as required, in some specific embodiments, for example, when the position of the test paper storage device 100 remains unchanged but the position of the opener changes, a plurality of interconnected paper outlet ends 4 may be provided to correspond to a plurality of test paper storage chambers 1.

[0036] The working principle of the automatic test paper feeding device disclosed in the present invention is as follows:

[0037] S1, placing a test paper in each test paper storage cavity 1 and sealing the test paper storage cavity 1 with a sealing layer 2;

[0038] S2. When paper feeding is required, the transmission device 300 controls the opening of a sealed test paper storage chamber 1 to align with the opening device;

[0039] S3, the opener destroys the sealing layer 2 of the test paper storage chamber 1;

[0040] S4, the transmission device 300 controls the opening of the test paper storage chamber 1 to align with the paper outlet end 4 of the test paper automatic feeding device;

[0041] S5. When paper feeding is required again, the transmission device 300 controls the opening of another sealed test paper storage chamber 1 to align with the opener and returns to step S3.

[0042] Compared with the prior art, the present invention packages and stores the test papers separately, and then uses the opening device 200 to unseal each test paper storage cavity 1 one by one, which not only ensures the effectiveness of the test papers, but also enables continuous paper feeding.

[0043] In a specific implementation, the test paper storage chambers 1 in the test paper storage device 100 are arranged in a circular array. When the transmission device 300 changes the relative position and / or posture of the test paper storage device 100 and the opening device 200, the opener rotates relative to the array axis of the test paper storage chambers 1.

[0044] In this way, the opener only needs to rotate relative to the test paper storage device 100 to align the opener with the openings of each test paper storage cavity 1 one by one. Since the rotational motion is easy to achieve and the angle of each rotation is easy to control, the structural complexity and control difficulty of the entire device can be reduced. Figure 3 and Figure 4 In addition to the above methods, you can also Fig. 9 As shown, the opening is arranged on the outer side of the test paper storage cavity 1, and the opener is in a long strip shape.

[0045] In a specific implementation, the test paper storage device 100 includes a rotating connection part 10, which is connected to the output end of the transmission device 300. The test paper storage cavity 1 takes the rotating axis 5 of the rotating connection part 10 as the array axis. All the test paper storage cavities 1 are parallel to each other and their openings face the same direction. The transmission device 300 is used to drive the test paper storage device 100 to rotate around the rotating axis 5, so that the opening of each test paper storage cavity 1 is first aligned with the opener and then with the paper outlet end 4 of the test paper automatic feeding device.

[0046] As a further optimization scheme, the opening direction is unified and the test paper storage cavity 1 is arranged in a circle around the rotating shaft 5, so that the positions of the paper outlet end 4 of the automatic test paper feeding device and the opener can be kept unchanged. Only by rotating the test paper storage device 100, the opening of the test paper storage cavity 1 and the opener and the paper outlet end 4 of the automatic test paper feeding device can be aligned in sequence. At this time, the transmission device 300 can only include one transmission motor 6, and at this time, only one paper outlet end 4 needs to be set at a fixed position, which further reduces the complexity of the structure.

[0047] In a specific implementation, the opener includes an opening portion 3 that can move back and forth, and the opening portion 3 can move to a first position to puncture the sealing layer 2 at the opening of any test paper storage cavity 1 when aligned with the opening of the test paper storage cavity 1, and move to a second position to exit the opening of the test paper storage cavity 1 when the opening of the test paper storage cavity 1 is aligned with the paper outlet end 4 of the automatic test paper feeding device.

[0048] like Figure 2 As shown, when the opening portion 3 is reciprocating, the opening portion 3 can be reciprocated by a motor plus a cam mechanism, a gear transmission mechanism, a threaded screw transmission mechanism 8 or a connecting rod mechanism. Fig.10As shown, an opening portion 3 with an inclined surface is used, and a spring is arranged on the side of the opening portion 3 facing away from the test paper storage chamber 1, and the reciprocating motion of the opening portion 3 is completed by the mutual compression between the opening end of the test paper storage chamber 1 and the inclined surface of the opening portion 3. The motor drives the cam or connecting rod device to achieve reciprocating motion, which is a prior art and will not be described in detail here.

[0049] In specific implementation, the test paper storage cavity 1 is vertically arranged and opened downward, and the opening 3 is adjacent to the vertical projection of a circle formed by connecting the centers of all the test paper storage cavities 1 with the paper outlet end 4 of the automatic test paper feeding device.

[0050] At this time, when the test paper storage device 100 rotates, the test paper storage cavity 1 will first be located above the opening 3. After the opening 3 pierces the sealing layer 2, the test paper storage device 100 continues to rotate, and the test paper storage cavity 1 with the pierced sealing layer 2 is aligned with the paper outlet end 4 of the test paper automatic paper feeding device. No other device is required. The test paper can automatically slide to the paper outlet end 4 under the action of gravity.

[0051] During specific implementation, the automatic test paper feeding device also includes a processor, and the opening device 200 also includes a driving device. The processor is used to control the transmission device 300 to drive the test paper storage cavity 1 to rotate around its array axis, so that the opening of each test paper storage cavity 1 is first aligned with the opener and then with the paper outlet end 4 of the automatic test paper feeding device; the processor is also used to control the driving device so that the driving device drives the opening portion 3, so that the opening portion 3 can move to the first position to pierce the sealing layer 2 at the opening of the paper storage cavity when it is aligned with the opening of any test paper storage cavity 1, and move to the second position to exit the opening of the test paper storage cavity 1 when the opening of the test paper storage cavity 1 is aligned with the paper outlet end 4 of the automatic test paper feeding device.

[0052] like Figure 6 As shown, in the present invention, a processor (MCU) can be used to control a stepper motor (both the driving device and the transmission device 300 can include a stepper motor), thereby controlling the rotation of the test paper storage device 100 and the reciprocating motion of the opening 3 to achieve automatic paper feeding.

[0053] In a specific implementation, the opening of the test paper storage cavity 1 is a tapered opening 9 with a gradually increasing width, and the opening portion 3 matches the shape of the tapered opening 9 .

[0054] like Figure 4 and Figure 5 As shown, the conical opening 9 is not only convenient for packaging of the test paper, but also during the unpacking process, the use of the conical opening 9 and the matching opening portion 3 can reduce the position accuracy requirements of the opening portion 3 and the opening of the test paper storage cavity 1 when the opening portion 3 pierces the sealing layer 2, thereby improving the stability of the device.

[0055] During specific implementation, the test paper storage device 100 is detachably mounted on the test paper automatic feeding device.

[0056] In the present invention, the test paper storage device 100 adopts a detachable structure, so that when the test paper on a test paper storage device 100 is used up, only the test paper storage device 100 can be replaced and the device can be used continuously, thereby extending the service life of the entire device. Figure 3 As shown, the rotating connection part 10 can be a polygonal hole, and the output end of the transmission device 300 is a corresponding polygonal shaft. The test paper storage device 100 can be assembled and disassembled by plugging. In addition, the polygonal hole can also play a role of rotation limit to ensure the rotation accuracy of the test paper storage device 100.

[0057] The following is a preferred embodiment of the present invention:

[0058] A test paper automatic feeding device includes a processor, a test paper storage device 100, an opening device 200 and a transmission device 300. The test paper storage device 100 includes a rotating connection part 10 and a plurality of test paper storage chambers 1 fixedly connected to the rotating connection part 10. Specifically, there can be 30 test paper storage chambers 1. The test paper storage chambers 1 are arranged in a circular array relative to a rotating shaft 5. The rotating shaft 5 and the test paper storage chambers 1 are both arranged vertically and the openings of the test paper storage chambers 1 are downward. The transmission device 300 includes a transmission motor 6. The output end of the transmission motor 6 is detachably connected to the rotating connection part 10. The transmission motor 6 can drive the test paper storage device 100 to rotate around the rotating shaft 5 of the rotating connection part 10. The opening device 200 includes a drive motor 7 and an opening part 3. The opening 3 and the paper outlet 4 of the automatic paper feeding device for test paper are arranged adjacent to each other along the vertical projection of the circle formed by connecting the centers of all the test paper storage chambers 1, and the driving motor 7 can drive the driving rod below the opening 3 through the threaded screw transmission device 300 to drive the opening 3 to reciprocate up and down; the processor is respectively connected to the transmission motor 6 and the driving motor 7 for communication, and when paper feeding is required, the processor controls the transmission motor 6 to rotate the test paper storage device 100 so that a sealed test paper storage chamber 1 is aligned with the opening 3, and then controls the driving motor 7 to drive the opening 3 to pierce the sealing layer 2 upward and then move downward to exit the opening 3, and then controls the transmission motor 6 to rotate the test paper storage device 100 so that the opening of the test paper storage chamber 1 is aligned with the paper outlet 4, so that the test paper slides into the paper outlet 4. In order to make the test paper slide into the paper outlet 4 smoothly, therefore, in the process of the test paper storage chamber 1 moving from aligning with the opening 3 to aligning with the paper outlet 4, the side of the opening 3 facing the paper outlet 4 is always higher than the side of the paper outlet 4 facing the opening 3.

[0059] In this embodiment, an angle sensor can be installed on the output shaft of the transmission motor 6 to collect and control the rotation angle of the test paper storage device 100. In addition, the processor can record the number of paper feeds through existing programming technology, and when all the test papers in the test paper storage device 100 are used up, the staff is prompted.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described with reference to the preferred embodiments of the present invention, it should be understood by those skilled in the art that various changes may be made in form and details without departing from the spirit and scope of the present invention as defined in the appended claims.
