[0032] Example, referring to Figures 1 to 8, A quality inspection test device for a medical device circuit board, including a detection base 1 and a detection cover 2 for detecting a hearing aid device 3. A sound receiving unit 4 and a sound amplifying unit 5 are arranged in the hearing aid device 3. The top end of the detection base 1 is fixedly connected with a protruding top seat 6 through two support rods. The top end of the protruding top seat 6 is connected with a water storage tank 7. The water storage tank 7 is connected with an atomization assembly for simulating an external humid environment through a hose;

[0033] Furthermore, a positioning groove adapted to the hearing aid device 3 is opened at the top end of the detection base 1. A noise reduction chip is arranged between the sound receiving unit 4 and the sound amplifying unit 5. The top end of the protruding top seat 6 is fixedly connected with the bottom end of the water storage tank 7. The atomization assembly is composed of a pressurized outer frame 8 and a plurality of atomizing nozzles 9. The water storage tank 7 is interconnected with the pressurized outer frame 8 through a hose. The inner side wall of the pressurized outer frame 8 is fixedly connected with the outer side wall of the detection cover 2. The bottom end of the pressurized outer frame 8 is fixedly connected with the top ends of the plurality of atomizing nozzles 9. A pressurizing pump is arranged in the water storage tank 7;

[0034] It should be noted that: Place the internal space of the hearing aid device 3 to be detected upward in the positioning groove on the detection base 1, and place each component in the hearing aid device 3 upward, which is convenient for subsequent detection. Then start the hydraulic cylinder 10 at the bottom end of the protruding top seat 6 to drive the detection cover 2 to move downward, so that the detection cover 2 is adaptively docked with the hearing aid device 3 fixed in the positioning groove, simulating the state after the outer shell of the hearing aid device 3 is encapsulated. Then start the pressurizing pump in the water storage tank 7, press the water into the pressurized outer frame 8 through the hose, and spray it out through the plurality of atomizing nozzles 9, so that the hearing aid device 3 is in the water mist, simulating the humid environment in which the hearing aid device 3 is located during daily use. Then start the negative pressure air pump 26 to gradually extract the air in the space of the hearing aid device 3 and the detection cover 2, so that the space is in a negative pressure state, which is convenient for the external humid air to penetrate and dissipate into the hearing aid device 3 faster. During this process, the conductive test of the circuit board in the hearing aid device 3 is continuously carried out through the contact guide rod 11, and the circuit change situation of the entire circuit board is recorded;

[0035] The benefits based on the above are: In this way, a humid environment in which the hearing aid device 3 is used daily can be simulated by using a plurality of atomizing nozzles 9, and the external humid air can be quickly penetrated and diffused into the interior by using the negative pressure state in the hearing aid device 3. The state of the circuit board in the hearing aid device 3 being affected by moisture after long-term use is simulated in a short time, which is convenient for dynamic real-time detection during the process of the circuit board being gradually affected by moisture, and quickly detects the moisture-proof performance of the circuit board in the hearing aid device 3;

Measuring and pulling telescopic rods 22 are arranged on both the left and right sides of the contact guide rods 11. The outer side wall of the fixed end of the measuring and pulling telescopic rods 22 is connected with a pair of photoelectric sensors 25. A wire pulling assembly is arranged below the pair of photoelectric sensors 25;

[0037] Furthermore, the bottom end of the convex extension top seat 6 is fixedly connected to the top end of the detection cover 2 through a hydraulic cylinder 10. A test power supply is arranged in the detection cover 2 and electrically connected to a plurality of contact guide rods 11. The wire pulling assembly consists of an arc surface seat 23 and two wire pulling rods 24. The inner end surface of the detection cover 2 is fixedly connected to the top end of the arc surface seat 23 through a wire pulling telescopic rod 22. Both side walls of the arc surface seat 23 are slidably connected to the two wire pulling rods 24 respectively. The wire pulling rod 24 is of a hydraulic push rod structure;

[0038] It should be noted that after the detection cover 2 is lowered and docked, the two wire pulling rods 24 inside the arc surface seat 23 will be hydraulically pushed outwards, so that the wire pulling rods 24 extend into the lower part of the welding lines in front of and behind the circuit board in the hearing aid device 3. When the detection cover 2 is separated and lifted later, the detection cover 2 will be controlled to lift at a slow speed, then the welding lines in front of and behind the circuit board in the hearing aid device 3 will be gradually pulled by the wire pulling rods 24. If the welding lines are qualified, the distance measured by the opposed photoelectric sensor 25 on the wire pulling telescopic rod 22 from the arc surface seat 23 will remain unchanged in a short time, and the wire pulling rods 24 will be controlled to retract quickly. If the welding lines are unqualified and break or fall off during the pulling process, the distance between the opposed photoelectric sensor 25 and the arc surface seat 23 will instantaneously become smaller, so that it will be measured and a signal will be transmitted, indicating that the measurement of the welding lines is unqualified;

[0039] The benefits based on the above are as follows: By measuring the change in the distance between the opposed photoelectric sensor 25 and the arc surface seat 23, the strength of the welding lines between the circuit board and other components in the narrow space of the hearing aid device 3 can be understood, ensuring the quality of the produced hearing aids;

[0040] Probe columns 12 are fixedly connected to the inner end surfaces of the detection cover 2 directly above the sound receiving unit 4 and the sound amplifying unit 5. An electromagnetic moving ring 13 is slidably connected to the outer side wall of the probe column 12. The bottom end of the electromagnetic moving ring 13 is connected to a retaining magnetic ring 15 through a return spring 14. The bottom end of the retaining magnetic ring 15 is respectively connected to a plurality of sealing components for isolating the sound receiving unit 4 and the sound amplifying unit 5 through a plurality of steering pin shafts 16;

[0041] Furthermore, the inner end face of the detection cover 2 is fixedly connected to the top end of the probe post 12. The bottom end of the electromagnetic moving ring 13 is fixedly connected to the top end of the retention magnetic ring 15 through a return spring 14. The sealing assembly is composed of an arc plate 17 and a spherical cover 18. The bottom end of the retention magnetic ring 15 is rotatably connected to the top end of the arc plate 17 through a steering pin shaft 16. The bottom end of the arc plate 17 is fixedly connected to the top end of the spherical cover 18. A torsion spring is arranged on the outer side wall of the end of the steering pin shaft 16. The bottom end of the electromagnetic moving ring 13 is rotatably connected with a plurality of compensation traction rods 19. A compensation groove is formed on the outer side wall of the arc plate 17. The inner side wall of the outer end of the compensation groove is rotatably connected to the bottom end of the compensation traction rod 19. The spherical cover 18 is made of rubber material, and a sound insulation material is arranged on the inner side wall of the spherical cover 18. A loudspeaker device 20 is fixedly connected to the bottom end of the probe post 12 above the sound receiving unit 4, and a micro decibel meter 21 is fixedly connected to the bottom end of the probe post 12 above the sound amplification unit 5. A negative pressure air pump 26 is fixedly connected to the top end of the detection cover 2;

[0042] It should be noted that when the detection cover 2 is docked and moved downward, the electromagnetic moving ring 13 is energized, so that the bottom end of the electromagnetic moving ring 13 and the top end of the retention magnetic ring 15 have opposite magnetic poles. Then, the electromagnetic moving ring 13 is attracted by the magnetic force and moves downward. The downward movement of the electromagnetic moving ring 13 will drive a plurality of compensation traction rods 19 to move downward together. Then, the bottom end of the compensation traction rod 19 will push the arc plate 17 obliquely downward, so that a plurality of arc plates 17 rotate downward through the steering pin shaft 16, and then drive a plurality of spherical covers 18 to rotate and gather, so that the sound receiving unit 4 and the sound amplification unit 5 in the hearing aid device 3 are in a relatively independent sealed state. Subsequently, the loudspeaker device 20 in the sealed space where the sound receiving unit 4 is located emits normal sounds and noise without frequency regularity respectively, and by observing the sound change detected by the micro decibel meter 21 in the sealed space where the sound amplification unit 5 is located, it can be known whether the function of the noise reduction chip on the circuit board in the hearing aid device 3 is affected during the above detection process;

[0043] The benefits based on the above are as follows: In this way, the gathering change of a plurality of spherical covers 18 can be utilized to make the sound receiving unit 4 and the sound amplification unit 5 in the hearing aid device 3 both in an independent sealed state, avoiding mutual influence during the close-range detection process. According to the control change of different sound reception and transmission, it is possible to detect whether the noise reduction function of the hearing aid device 3 is damaged during the detection process;

[0044] When the present invention is in use, the hearing aid device 3 to be detected is placed with its internal space facing upward in the positioning groove on the detection seat 1, and each component inside the hearing aid device 3 is placed facing upward for subsequent detection. Then, the hydraulic cylinder 10 at the bottom of the convex extension top seat 6 is started to drive the detection cover 2 to move downward, so that the detection cover 2 is adaptively docked with the hearing aid device 3 fixed in the positioning groove (the air in the gap after docking can enter), simulating the state after the outer shell of the hearing aid device 3 is encapsulated. Then, the pressure pump in the water storage tank 7 is started, and water is pressed into the pressure outer frame 8 through a hose and sprayed out through a plurality of atomizing nozzles 9, so that the hearing aid device 3 is in the water mist, simulating the humid environment in which the hearing aid device 3 is located during daily use. Then, the negative pressure air pump 26 is started to gradually extract the air in the space of the hearing aid device 3 and the detection cover 2, making the space in a negative pressure state, so as to facilitate the faster penetration and diffusion of the external humid air into the hearing aid device 3. During this process, the conductive test of the circuit board in the hearing aid device 3 is continuously carried out through the contact guide rod 11, and the circuit change situation of the entire circuit board is recorded. This is the prior art and will not be elaborated here. In this way, a humid environment in which the hearing aid device 3 is located during daily use can be simulated by using a plurality of atomizing nozzles 9, and the external humid air can be quickly penetrated and diffused into the interior by using the negative pressure state in the hearing aid device 3, and the state of the circuit board in the hearing aid device 3 being affected by moisture after long-term use can be simulated in a short time. According to the circuit changes during the inspection process, it is convenient to carry out dynamic real-time detection during the process of the circuit board being gradually affected by moisture, and quickly detect the moisture-proof performance of the circuit board in the hearing aid device 3 (the circuit board in the hearing aid is usually moisture-proof treated, and this is to detect the moisture-proof performance after the moisture-proof treatment of the circuit board);

[0045] After the detection cover 2 moves downward and docks, two pull wire rods 24 in the arc-shaped seat 23 will be controlled to be hydraulically pushed outwards, so that the pull wire rods 24 extend under the welding lines in the front and back of the circuit board in the hearing aid device 3. When the detection cover 2 separates and moves upward later, the detection cover 2 will be controlled to move upward at a slow speed, then the welding lines in the front and back of the circuit board in the hearing aid device 3 will be gradually pulled by the pull wire rods 24. If the welding lines are qualified, the distance between the opposed photoelectric sensor 25 on the pull and stretch rod 22 to be measured and the arc-shaped seat 23 is determined to be unchanged in a short time, and the pull wire rods 24 will be controlled to retract quickly. If the welding lines are unqualified and break or fall off during the pulling process, the distance between the opposed photoelectric sensor 25 and the arc-shaped seat 23 will instantaneously become smaller, so that it can be detected and a signal is transmitted, indicating that the measurement of the welding lines is unqualified. In this way, the change in the distance between the opposed photoelectric sensor 25 and the arc-shaped seat 23 can be used to understand the strength of the welding lines between the circuit board and other components in the narrow space of the hearing aid device 3, ensuring the quality of the produced hearing aids;

[0046] When detecting the downward docking of the cover 2, the electromagnetic moving ring 13 is electrified, so that the bottom end of the electromagnetic moving ring 13 and the top end of the retention magnetic ring 15 have opposite magnetic poles. Then, the electromagnetic moving ring 13 is pulled downward by the magnetic suction force. The downward movement of the electromagnetic moving ring 13 drives a plurality of compensation traction rods 19 to move downward together. Then, the bottom end of the compensation traction rod 19 obliquely pushes the arc-shaped plate 17 downward, so that a plurality of arc-shaped plates 17 rotate downward through the steering pin shafts 16, and then drive a plurality of spherical covers 18 to rotate and gather, so that the sound receiving unit 4 and the sound amplifying unit 5 in the hearing aid device 3 are in a relatively independent sealed state. Subsequently, the sound emitting device 20 in the sealed space where the sound receiving unit 4 is located emits normal sound and noise without frequency regularity respectively. By observing the sound change detected by the micro decibel meter 21 in the sealed space where the sound amplifying unit 5 is located, it can be known whether the noise reduction chip function on the circuit board in the hearing aid device 3 is affected during the above detection process. In this way, the gathering change of a plurality of spherical covers 18 can be used to make the sound receiving unit 4 and the sound amplifying unit 5 in the hearing aid device 3 both in an independent sealed state, avoiding mutual influence during the close-range detection process. According to the contrast change of different sound reception and transmission, it is detected whether the noise reduction function of the hearing aid device 3 is damaged during the detection process.

[0047] 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 and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
