Technical Field
[0001] The present invention relates to the technical field of electronic sphygmomanometer detection, and particularly relates to a detection instrument and method for an electronic sphygmomanometer. Background Art
[0002] During the production process of an electronic sphygmomanometer, in order to ensure product quality, sampling inspection is carried out from the corresponding batches to detect the influence of different situations on the normal use of the electronic sphygmomanometer. The specific test is to first simulate corresponding conditions on the electronic sphygmomanometer, and then use an LCR tester to test the resistance or capacitance of the electronic sphygmomanometer to detect whether the electronic sphygmomanometer can be used normally after experiencing the corresponding conditions. However, the existing detection instruments are relatively inconvenient to operate. After the electronic sphygmomanometer experiences the corresponding simulation conditions, it needs to be manually taken and moved to the position where the LCR tester is located for testing. Especially when multiple different conditions need to be simulated for testing, it becomes even more inconvenient. Therefore, we propose a detection instrument and method for an electronic sphygmomanometer to solve the above problems. Summary of the Invention
[0003] The purpose of the present invention is to solve the problems raised in the background art, and propose a detection instrument and method for an electronic sphygmomanometer.
[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0005] A detection instrument for an electronic sphygmomanometer includes a detection cylinder, a sphygmomanometer, a tester one, and a tester two. A test hole is provided on the sphygmomanometer. A test column is fixed on the detection cylinder, and the test column is connected to the tester one and the tester two through connecting wires.
[0006] A test power supply component and a vibration test component are arranged on the detection cylinder. Two reciprocating screws are rotatably installed on the detection cylinder, and a power transmission component is arranged between the reciprocating screws and the test power supply component. The two reciprocating screws are installed with an installation ring through ball nuts and lifting frames, and a drop test component matching the sphygmomanometer is arranged on the installation ring.
[0007] A gear ring one is rotatably installed on the installation ring. Transmission frames meshing with the gear ring one are rotatably installed on both lifting frames. A variable-speed transmission component is installed between the reciprocating screw and the detection cylinder. A temperature test component is installed between the installation ring and the gear ring one. The vibration test component, the temperature test component, and the drop test component are all cooperated with the tester one and the tester two to perform electrical tests on the sphygmomanometer.
[0008] A use method of a detection instrument for an electronic sphygmomanometer, using the above-mentioned detection instrument, includes the following steps:
[0009] S1: Vibration test. The distance between the clamping frame and the sphygmomanometer is maximized in the initial state. The sphygmomanometer is placed on the vibrating disk. The servo motor is started, and the working of the servo motor drives the main shaft to rotate. At this time, the one-way bearing 1 drives the eccentric disk to rotate. Through the cooperation of the spring rod and the eccentric rotation of the eccentric disk, the vibrating disk is driven to vibrate, thereby performing a vibration test on the sphygmomanometer.
[0010] After the vibration stops, control the main shaft to rotate in the reverse direction and at a high speed. At this time, the reciprocating screw rotates at a high speed, causing one end of the elastic block to be stuck in the card slot, thereby driving the ring to rotate. The rotation of the ring drives the transmission frame to rotate through the internal gear ring. The rotation of the transmission frame drives the gear ring 1 to rotate. The rotation of the gear ring 1 drives the rotating rod to rotate through the gear 2, thereby clamping the sphygmomanometer. After clamping, reduce the rotation speed of the reciprocating screw, causing the clamping frame to stop moving. Then the rotation of the reciprocating screw will drive the sphygmomanometer to move upward together. Stop moving at the highest point. At this time, the test column is inserted into the sphygmomanometer, and electrical tests are performed through the tester 1 and the tester 2.
[0011] S2: Drop test. Clamp the sphygmomanometer placed on the vibrating disk, then drive the sphygmomanometer to move upward to a certain height, and then increase the rotation of the reciprocating screw, so that the clamping frame moves away from the sphygmomanometer, enabling the sphygmomanometer to drop.
[0012] After dropping, the reciprocating screw continues to rotate, driving the clamping frame to move to the lowest position. Then increase the rotation speed of the reciprocating screw, clamp the sphygmomanometer, and move it to the highest position. Then electrical tests are performed through the tester 1 and the tester 2.
[0013] S3: Temperature test. The heating element works to generate the high temperature required for the test. Then the reciprocating screw rotates to drive the heating element to move in the vertical direction, and during the movement, it can be intermittent, or continuously control the transmission frame to rotate. The rotation of the transmission frame can continuously generate a suction force in the sliding disk, making the overall temperature in the detection cylinder more uniform.
[0014] After a period of time, clamp the sphygmomanometer and drive it to the highest position, and perform electrical tests through the tester 1 and the tester 2.
[0015] S4: The above tests are not in sequence and can be selected according to requirements. It is possible to perform a single test or a combined test.
[0016] Compared with the existing technology, the advantages of the present invention are as follows:
[0017] 1. It can quickly perform corresponding multiple different condition simulation tests on the sphygmomanometer, and quickly perform resistance and capacitance tests after the simulation condition tests, reducing the labor intensity of operators, shortening the test time required, and making the overall test more convenient.
[0018] 2: One servo motor can meet the corresponding motions required for various different simulation conditions. At the same time, it is also convenient to subsequently clamp and move the sphygmomanometer to the highest position for resistance and capacitance tests, making the overall operation more convenient.

Specific implementation manner
[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] Referring to Figures 1 - 15 , a detection instrument for an electronic sphygmomanometer includes a detection cylinder 1 and a sphygmomanometer 6 for testing. The sphygmomanometer 6 is specifically an electronic sphygmomanometer, and its specific shape is square or rectangular. The illustration in the figure is only for reference. For electronic sphygmomanometers of different sizes, only the initial position and the moving amplitude of the clamping frame 18 need to be controlled, so that when multiple clamping frames 18 move to the maximum position, they can contact the four sides of the electronic sphygmomanometer and tightly clamp it.
[0037] Two detectors are symmetrically and fixedly arranged on the detection cylinder 1, specifically LCR testers. For the convenience of understanding, they are named tester one 2 and tester two 3 respectively. They can respectively perform resistance testing and capacitance testing on the sphygmomanometer 6. One LCR tester can only perform one parameter test at a time. When performing another test, the mode of the LCR tester needs to be adjusted, and the insertion positions of the connection wire 5 for different tests are also different. This is specifically the prior art;
[0038] The sphygmomanometer 6 is provided with a plurality of test holes 7. A plurality of test columns 4 that cooperate with the test holes 7 are fixedly penetrated on the detection cylinder 1. The first tester 2 and the second tester 3 are connected by a connecting line 5 to the corresponding test columns 4. When the sphygmomanometer 6 is in the highest position, the lower end of the test column 4 is just located in the corresponding test hole 7 and contacts the corresponding electronic component in the sphygmomanometer 6. Then, when the sphygmomanometer 6 is turned on, the first tester 2 and the second tester 3 can be used for testing. Here, the opening method of the sphygmomanometer 6 can be set as required. For example, an electric telescopic rod is fixedly installed on the top wall of the detection cylinder 1. When the sphygmomanometer 6 moves to the highest position, the electric telescopic rod works. During the elongation process, it contacts and presses the start key of the sphygmomanometer 6, thereby realizing the start of the sphygmomanometer 6. After the test is completed, controlling the electric telescopic rod to perform one more telescopic operation is sufficient.
[0039] Refer to Figures 1 - 15 , a test power supply component is provided on the detection cylinder 1. The test power supply component includes a servo motor 8 and a main shaft 9. The servo motor 8 is fixedly installed outside the detection cylinder 1. The driving end of the servo motor 8 is fixedly installed with the main shaft 9, and one end of the main shaft 9 rotates inside the detection cylinder 1. As shown in the figure, a fixing frame is fixed outside the detection cylinder 1, and then the servo motor 8 is fixedly arranged on one side of the fixing frame. The fixing frame is not marked in the figure. Attached Figure 4 It can be clearly seen from the figure that the purpose of the setting is to improve the stability of the servo motor 8 during installation.
[0040] A vibration test component is provided on the detection cylinder 1. The vibration test component includes a one-way bearing I, an eccentric disc 10, a vibration disc 11, and an elastic connection component. Two eccentric discs 10 are installed on the main shaft 9 through two one-way bearings I, and the eccentric discs 10 are eccentrically installed on the main shaft 9. The two eccentric discs 10 are jointly attached to the vibration disc 11, and an elastic connection component is fixed between the vibration disc 11 and the bottom wall of the detection cylinder 1. The elastic connection component includes a plurality of spring rods 12. A plurality of spring rods 12 are fixedly installed between the lower surface of the vibration disc 11 and the bottom wall of the detection cylinder 1, and the spring rods 12 are symmetrically arranged on both sides of the main shaft 9. The vibration test component can perform a vibration test on the sphygmomanometer 6 placed thereon. The vibration provided by the vibration disc 11 can only make the sphygmomanometer 6 vibrate slightly, and the vibration cannot cause it to flip.
[0041] Two reciprocating screws 13 are rotatably installed on the inner top wall of the detection cylinder 1. Support frames are symmetrically and fixedly installed on the side wall of the detection cylinder 1, and the lower ends of the reciprocating screws 13 are rotatably installed on the corresponding support frames. The support frames are from the attached drawings of the specification Figure 6 、Attached Figure 8As can be seen from all of the above, the support frame includes two arc-shaped rods and a support block. Four arc-shaped rods are symmetrically and fixedly installed on the inner wall of the detection cylinder 1. A support block is fixedly installed by corresponding two arc-shaped rods. The lower end of the reciprocating screw 13 is specifically rotatably installed on the corresponding support block. A power transmission member is installed between the reciprocating screw 13 and the test power supply member. The power transmission member includes a one-way bearing two and a helical gear 14. A helical gear 14 is fixedly installed at the lower end of each of the two reciprocating screws 13. Two helical gears 14 are also installed on the main shaft 9 through two one-way bearings two. And the two helical gears 14 on the side of the sphygmomanometer 6 are meshed with each other. The self-locking directions of the one-way bearing one and the one-way bearing two are opposite. The support block is located on both sides of the two lower helical gears 14.
[0042] A lifting frame 15 is installed on each of the two reciprocating screws 13 through a ball nut. An installation ring 16 is fixedly installed between the two lifting frames 15. A dropping test member matched with the sphygmomanometer 6 is arranged on the installation ring 16. The test power supply member is used to provide power to control the vibration test member to perform a vibration test or a dropping test on the sphygmomanometer 6, and drive the sphygmomanometer 6 to move upward to cooperate with the tester one 2 and the tester two 3 for an electrical test after the vibration or dropping test. The dropping test member includes a rotating rod 17 and a clamping frame 18. A plurality of rotating rods 17 are rotatably installed on the installation ring 16. The part of the rotating rod 17 close to the sphygmomanometer 6 is provided with a reciprocating thread, and a clamping frame 18 matched with the sphygmomanometer 6 is installed on this part through a nut. The clamping frame 18 includes a moving block one, a cross bar, and a moving block two. A moving block one is installed on the nut. The moving block one is fixedly installed with a moving block two through a plurality of cross bars. An elastic gasket is fixedly arranged on the side of the moving block two away from the moving block one. An elastic airbag or a rubber pad can also be used to replace the elastic gasket. The purpose is to provide a buffering effect during contact and improve the firmness during clamping at the same time. In addition, it should also be noted that only when the rotating rod 17 rotates can the sphygmomanometer 6 be clamped. However, at this time, the rotation of the reciprocating screw 13 will also drive the lifting frame 15 and the rotating rod 17 to move together. At this time, to ensure that the clamping frame 18 clamps the sphygmomanometer 6, there are various ways in the prior art to achieve this, such as fixing the vertical rod (transmission frame 21) and the part where the lifting frame 15 is fixedly connected to the installation ring 16 ( Figure 13 As can be seen from the left part in the figure, it is fixed through an L-shaped frame rod. At this time, the vertical part is set), so that the position of the clamping frame 18 will not be changed during the initial rotation of the reciprocating screw 13. Or by setting the reciprocating threads on the reciprocating screw 13 and the rotating rod 17, so that although the clamping frame 18 will move upward with the rotation of the reciprocating screw 13, it can still clamp the sphygmomanometer 6.
[0043] The drop test component is used to drive the sphygmomanometer 6 to move within a certain height range, remove the clamping on the sphygmomanometer 6, and let it fall. It should be noted that to ensure the subsequent electrical tests in cooperation with the tester one 2 and the tester two 3, the sphygmomanometer 6 will not turn over during this drop. There are various ways in the prior art that can meet this requirement. For example, a plurality of elastic retaining rings are provided on the inner wall of the internal gear ring 23. When the sphygmomanometer 6 moves upward due to the impact force when it falls to the lowest point, it will contact the elastic retaining ring, thereby restricting its flipping.
[0044] Refer to Figures 1 - 15 , a gear ring one 20 is rotatably installed on the mounting ring 16. A gear two 19 is fixedly installed on each rotating rod 17, and the gear two 19 meshes with the gear ring one 20; a transmission frame 21 is rotatably installed on each of the two lifting frames 15. The transmission frame 21 includes an annular stepped slider, a vertical rod, and a gear two. An annular stepped chute is opened on the lower surface of each of the two lifting frames 15, and an annular stepped slider is rotatably installed on the annular stepped chute. A gear two is fixedly installed on the lower surface of the annular stepped slider through a plurality of vertical rods two, and the gear two meshes with the gear ring one 20. A variable speed transmission component is installed between the reciprocating screw rod 13 and the detection cylinder 1, and a temperature test component is installed between the mounting ring 16 and the gear ring one 20. The variable speed transmission component is used in cooperation with the temperature test component and the drop test component.
[0045] The variable speed transmission component includes a circular ring 22, an internal gear ring 23, an elastic clamping block 24, and a clamping groove 25. Two circular rings 22 are rotatably installed on the top wall of the detection cylinder 1, and the circular rings 22 cooperate with the corresponding reciprocating screw rods 13 respectively. The internal gear ring 23 is rotatably installed on the inner wall of the detection cylinder 1, and the internal gear ring 23 meshes with both circular rings 22 and both transmission frames 21 at the same time. Specifically, the gear two meshes with both circular rings 22 and the internal gear ring 23; the internal gear ring 23 is shown as a whole in the figure. When specifically set, it can also be set as two gear rings and a plurality of connecting rods for fixed support. The upper gear ring meshes with the circular ring 22, and the lower gear ring meshes with the gear ring one 20; a plurality of clamping grooves 25 are equally spaced on the inner walls of the two circular rings 22, and a plurality of clamping grooves 25 that cooperate with the elastic clamping blocks 24 are equally spaced and fixedly installed on the two reciprocating screw rods 13; the elastic clamping block 24 includes an elastic telescopic rod and a clamping block. A plurality of elastic telescopic rods are fixedly installed on the reciprocating screw rod 13, and a clamping block that cooperates with the clamping groove 25 is fixedly installed at one end of the elastic telescopic rod; the two side edges of the clamping groove 25 and the two side surfaces of the clamping block are both arc-shaped. This arc-shaped setting can facilitate better clamping. At the same time, an electric telescopic rod can also be used to replace the elastic clamping block 24. Then, when the whole device is used, it is not necessary to drive the circular ring 22 to rotate by adjusting the rotation speed of the reciprocating screw rod 13.
[0046] The temperature test component includes an annular plate 26, a control component, an air cylinder 28, a sliding disk 29, a vertical pipe, and a pipe body 30. An annular sliding groove is formed on the mounting ring 16, and the end face shape of the annular sliding groove is stepped. The annular plate 26 is rotatably mounted on the annular sliding groove, and the annular plate 26 is fixed to the first toothed ring 20. A plurality of air cylinders 28 are fixedly communicated with the mounting ring 16. The air cylinder 28 is fixedly communicated with a vertical pipe and a pipe body 30. A sliding disk 29 is hermetically and slidably mounted in each air cylinder 28, and a control component is arranged between the sliding disk 29 and the annular plate 26; the control component includes a magnetic block 27 and a communication groove. The lower end of the air cylinder 28 is open. A plurality of communication grooves are formed on the mounting ring 16, and the lower end of the communication groove is communicated with the annular sliding groove. A magnetic block 27 is fixedly mounted on the lower surface of each sliding disk 29, and a plurality of magnetic blocks 27 are also fixedly mounted on the annular plate 26. The adjacent two magnetic blocks 27 on the same horizontal plane have opposite magnetic polarities on the same side; a heating element is fixedly mounted on the mounting ring 16. The heating element is a prior art, such as an electric heater, and its operation can generate heat, thereby simulating the influence on the normal use of the sphygmomanometer 6 at a certain temperature.
[0047] Referring to Figures 1 - 15 , a usage method of a detection instrument for an electronic sphygmomanometer, using the above detection instrument, includes the following steps:
[0048] S1: Vibration test. In the initial state, the distance between the clamping frame 18 and the sphygmomanometer 6 is the largest. The sphygmomanometer 6 is placed on the vibrating disk 11. The servo motor 8 is started. The operation of the servo motor 8 drives the main shaft 9 to rotate. At this time, the one-way bearing one drives the eccentric disk 10 to rotate. Through the cooperation of the spring rod 12 and the eccentric rotation of the eccentric disk 10, the vibrating disk 11 is driven to vibrate, thereby performing a vibration test on the sphygmomanometer 6;
[0049] After the vibration stops, control the main shaft 9 to rotate in the reverse direction and at a high speed. At this time, the reciprocating screw 13 rotates at a high speed, so that one end of the elastic clamping block 24 is clamped into the clamping groove 25, thereby driving the ring 22 to rotate. The rotation of the ring 22 drives the transmission frame 21 to rotate through the internal toothed ring 23. The rotation of the transmission frame 21 drives the first toothed ring 20 to rotate. The rotation of the first toothed ring 20 drives the rotating rod 17 to rotate through the second gear 19, thereby clamping the sphygmomanometer 6. After clamping, reduce the rotation speed of the reciprocating screw 13, so that the clamping frame 18 stops moving. Then the rotation of the reciprocating screw 13 will drive the sphygmomanometer 6 to move upward together. Stop moving at the highest point. At this time, the test column 4 is inserted into the sphygmomanometer 6, and electrical tests are performed through the first tester 2 and the second tester 3;
[0050] S2: Drop test. Clamp the sphygmomanometer 6 placed on the vibrating disk 11, then drive the sphygmomanometer 6 to move up to a certain height, and then increase the rotation of the reciprocating screw 13, so that the clamping frame 18 moves away from the sphygmomanometer 6, and the sphygmomanometer 6 can be dropped;
[0051] After the fall, the reciprocating screw 13 continues to rotate to drive the clamping frame 18 to move to the lowest position. Then, the rotation speed of the reciprocating screw 13 is increased to clamp the sphygmomanometer 6 and move it to the highest position. Then, electrical tests are performed through the tester 1 2 and the tester 2 3.
[0052] S3: Temperature test. The heating element works to generate the high temperature required for the test. Then, the reciprocating screw 13 rotates to drive the heating element to move in the vertical direction. During the movement, it can be intermittent, or the rotation of the transmission frame 21 is always controlled. The rotation of the transmission frame 21 can continuously generate a suction force in the sliding disk 29, making the overall temperature in the detection cylinder 1 more uniform.
[0053] After a period of time, the sphygmomanometer 6 is clamped and driven to the highest position, and electrical tests are performed through the tester 1 2 and the tester 2 3.
[0054] S4: The above tests are not in sequence and can be selected according to requirements. It is possible to perform a single test or a combined test.
[0055] Further explanation, the above fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.
[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

6. A method for using a detection instrument of an electronic sphygmomanometer, using the detection instrument as described in claim 5, characterized in that, It includes the following steps: S1: Vibration test. In the initial state, the distance between the clamping frame (18) and the sphygmomanometer (6) is the largest. The sphygmomanometer (6) is placed on the vibrating disk (11). The servo motor (8) is started, and the servo motor (8) drives the main shaft (9) to rotate. At this time, the one-way bearing one drives the eccentric disk (10) to rotate. Through the cooperation of the spring rod (12) and the eccentric rotation of the eccentric disk (10), the vibrating disk (11) is driven to vibrate, and then the vibration test of the sphygmomanometer (6) is carried out. After the vibration stops, control the main shaft (9) to rotate in the reverse direction and at a high speed. At this time, the reciprocating screw rod (13) rotates at a high speed so that one end of the elastic clamping block (24) is clamped into the clamping groove (25), and then the ring (22) is driven to rotate. The rotation of the ring (22) drives the transmission frame (21) to rotate through the internal gear ring (23). The rotation of the transmission frame (21) drives the gear ring one (20) to rotate. The rotation of the gear ring one (20) drives the rotating rod (17) to rotate through the gear two (19), and then the sphygmomanometer (6) is clamped. After clamping, reduce the rotation speed of the reciprocating screw rod (13) so that the clamping frame (18) stops moving. Then the rotation of the reciprocating screw rod (13) will drive the sphygmomanometer (6) to move upward together. Stop moving at the highest point. At this time, the test column (4) is inserted into the sphygmomanometer (6), and the electrical test is carried out through the tester one (2) and the tester two (3). S2: Drop test. Clamp the sphygmomanometer (6) placed on the vibrating disk (11), then drive the sphygmomanometer (6) to move upward to a certain height, and then increase the rotation of the reciprocating screw rod (13), so that the clamping frame (18) moves away from the sphygmomanometer (6), and then the sphygmomanometer (6) can be dropped. After dropping, the reciprocating screw rod (13) continues to rotate to drive the clamping frame (18) to move to the lowest position, then increase the rotation speed of the reciprocating screw rod (13), clamp the sphygmomanometer (6), and move it to the highest position, and then the electrical test is carried out through the tester one (2) and the tester two (3). S3: Temperature test. The heating element works to generate the high temperature required for the test, and then the reciprocating screw rod (13) rotates to drive the heating element to move in the vertical direction. During the movement, it can be intermittent, or the transmission frame (21) is always controlled to rotate. The rotation of the transmission frame (21) can continuously generate suction force in the sliding disk (29), making the overall temperature in the detection cylinder (1) more uniform. After a period of time, clamp the sphygmomanometer (6) and drive it to the highest position, and the electrical test is carried out through the tester one (2) and the tester two (3). S4: The above tests are not in order and can be selected according to needs. A single test can be carried out, or a combined test can be carried out.
