DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1 A test device for the production of record player parts, such as Figure 1-11 As shown, it includes a base 1, a shell 2 and a door 3; the base 1 is bolted to the shell 2; the shell 2 is hinged to the door 3; It also includes a supporting plate 4, a pneumatic push rod 5, a connecting plate 6, a ventilation frame 7, a suction cup 8, a telescopic hose 9, a connecting plate 10, a winding roller 11, a film 12, a camera 13 and an air extraction box 14; the base 1 is bolted to the supporting plate 4; the pneumatic push rod 5 is bolted inside the shell 2; the telescopic part of the pneumatic push rod 5 is bolted to the connecting plate 6; the connecting plate 6 is fixedly connected to the ventilation frame 7; the ventilation frame 7 is connected to at least four suction cups 8 through the connecting plate 6; the ventilation frame 7 is connected to the telescopic hose 9, and the telescopic hose 9 is connected to the air pump through the air pump. The base 1, the shell 2 and the supporting plate 4 are connected together with a connecting plate 10; the connecting plate 10 is provided with a through slot 10a; the connecting plate 10 is rotatably connected with a winding roller 11; the winding roller 11 winds up a film 12, and the end of the film 12 is exposed from the through slot 10a, and the thickness of the film 12 is slightly smaller than the distance between the record 001 and the turntable 002a; at least two cameras 13 are installed inside the shell 2; the shell 2 is installed with an exhaust box 14, and the exhaust port of the exhaust box 14 is connected with the inside of the shell 2.

[0021] It also includes an exhaust plate 101; the connecting plate 6 is bolted to the exhaust plate 101, and the exhaust plate 101 is in contact with the inner wall of the shell 2. When the exhaust plate 101 moves downward following the connecting plate 6, the exhaust plate 101 in contact with the inner wall of the shell 2 can quickly squeeze the air inside the shell 2 downward, assisting the vacuum box 14 to perform a vacuum operation, thereby accelerating the vacuum speed and improving the test efficiency.

[0022] The supporting plate 4 can be provided with a placement groove, which does not require manual correction and can be placed by snapping in, making the operation simple and efficient.

[0023] The present invention specifically works as follows: The work of the record player is mainly composed of record 001, base 002, cartridge 003, turntable 002a and central shaft 002b; like Figure 4 As shown, first, the staff first places the base 002 with the record 002a placed on the supporting plate 4, then puts the record 001 close to the suction cup 8, and controls the air pump to evacuate air through the telescopic hose 9, the ventilation rack 7 and the suction cup 8, so that the suction cup 8 generates suction, and the record 001 is sucked by the suction cup 8, so that the record 001 is directly opposite to the base 002 below, and then the staff pulls the film 12 off the winding roller 11, so that the part of the film 12 exposed in the through groove 10a is located on the upper surface of the record 002a; then, the staff manually closes the door 3, so that the inside of the shell 2 is in a closed state; Subsequently, the air extraction box 14 is controlled to extract the air inside the housing 2 through the air extraction port thereon, so that the inside of the housing 2 is close to a vacuum state, thereby reducing sound propagation, avoiding the generation of noisy noise during the detection process, and preventing noise pollution in the detection workshop; Subsequently, the telescopic part of the pneumatic push rod 5 is controlled to drive the connection plate 6, the ventilation frame 7, the suction cup 8 and the record 001 to move downward, until the record 001 is engaged with the central rotating shaft 002b on the base 002, so that there is a gap between the lower surface of the record 001 and the upper surface of the turntable 002a, wherein the telescopic hose 9 is adaptively telescoped with the movement of the ventilation frame 7; at this time, the part of the film 12 exposed in the through groove 10a is located between the upper surface of the turntable 002a and the lower surface of the record 001; subsequently, the air pump is controlled to be turned off, and the suction cup 8 will lose its suction force on the record 001, so that the suction cup 8 is separated from the record 001, and then the telescopic part of the pneumatic push rod 5 is controlled to drive the connection plate 6, the ventilation frame 7 and the suction cup 8 to move upward, away from the record 001, so as to avoid affecting the normal operation of the subsequent record 001; Then, the base 002 is controlled to operate, and the base 002 drives the turntable 002a and the central shaft 002b to rotate, so that the central shaft 002b drives the record 001 to rotate synchronously with the turntable 002a; In the above-mentioned rotation process, if the turntable 002a or the central rotating shaft 002b rotates unstably, then the turntable 002a or the record 001 will not rotate in a standard horizontal manner, but will rotate in an up-and-down manner. Since the thickness of the film 12 is slightly smaller than the distance between the record 001 and the turntable 002a, during the rotation of the record 001 and the turntable 002a, the lower surface of the record 001 and the upper surface of the turntable 002a will rub against the portion of the film 12 exposed in the through groove 10a. In this way, after the record 001 and the turntable 002a rotate for a period of time, the portion of the film 12 exposed in the through groove 10a will form wrinkles. Subsequently, the telescopic portion of the pneumatic push rod 5 is controlled to drive the connecting plate 6, the ventilation frame 7 and the suction cup 8 downward to the record 001, and the air pump is started to provide suction for the suction cup 8, so that the suction cup 8 sucks the record 001, and then the telescopic portion of the pneumatic push rod 5 is controlled to drive the connecting plate 6, the ventilation frame 7, the suction cup 8 and the record 001 to move upward, away from the turntable 002a, so that the camera 13 can observe whether there are wrinkles on the film 12. If the camera 13 observes that there are wrinkles on the film 12, it is determined that the rotation of the turntable 002a or the record 001 itself is unstable, and the test result is obtained, confirming that there is a problem with the turntable 002a or the central shaft 002b. In this way, compared with traditional testing technology, the present invention can intuitively present the problems on the turntable 002a or the central shaft 002b through the wrinkles on the film 12, and can accurately and specifically determine whether there are defects in the turntable 002a or the central shaft 002b.

[0024] Example 2 On the basis of Example 1, Figure 7-11 As shown, it also includes an electric drive plate 201 and a second film 203 ; the housing 2 is equipped with two arc-shaped electric drive plates 201 ; and the rotating part of the electric drive plate 201 away from the camera 13 is provided with a second film 203 .

[0025] It also includes a rubber pad 202; each rotating part of the electric drive paddle 201 is provided with a soft rubber pad 202, and the soft rubber pad 202 replaces the electric drive paddle 201 to contact the cartridge 003, thereby reducing the damage of the electric drive paddle 201 to the cartridge 003.

[0026] It also includes an electric push rod 211, a pressure plate 212 and a receiving plate 213; the rotating part of the electric drive plate 201 away from the camera 13 is bolted to the electric push rod 211; the telescopic part of the electric push rod 211 is bolted to the pressure plate 212, and the pressure plate 212 is located above the film 203; the rotating part of the electric drive plate 201 away from the camera 13 is fixedly connected to the receiving plate 213; the receiving plate 213 is provided with a receiving groove 213a, and the receiving groove 213a matches the pressure plate 212; the film 203 has elastic deformation capability.

[0027] The pressing plate 212 is provided with an inclined portion 1 212a; the accommodating groove 213a is provided with an inclined portion 213b, and the inclined portion 213b corresponds to the inclined portion 1 212a.

[0028] The present invention specifically works as follows: After the above record 001 test, several flawless records 001 can be obtained. Subsequently, one of the flawless records 001 is placed on the turntable 002a and the central shaft 002b according to the steps in Example 1, and the record 001 and the turntable 002a are rotated synchronously. Subsequently, the electric drive paddle 201 away from the camera 13 is controlled to paddle the pickup 003, so that the pickup 003 is close to the record 001 and contacts the sound groove on the record 001, and the electric drive paddle 201 is kept in position unchanged, so that the film 203 on the electric drive paddle 201 can fall on the pickup 003 under the action of gravity. When the record player is working, the stylus on the pickup 003 will vibrate up and down along with the uneven sound grooves on the surface of the record 001, and then be converted into a weak electrical signal by the pickup 003, and then amplified by the amplifier on the pickup 003, so that the pickup 003 generates a sustained sound. When the stylus on the cartridge 003 vibrates, the cartridge 003 will also vibrate, and at the same time, the sound waves generated by the cartridge 003 will cause the film 203 on the cartridge 003 to vibrate. In this way, the camera 13 is used to observe whether the film 203 vibrates, and the specific sounding condition of the cartridge 003 is determined based on the vibration amplitude and vibration frequency of the film 203. If the camera 13 observes that the film 203 can vibrate continuously and stably, it is determined that the cartridge 003 has no defects. If the camera 13 observes that the film 203 vibrates intermittently or does not vibrate, it is determined that the cartridge 003 has defects. In this way, compared with the traditional sound testing technology, the present invention intuitively presents whether the cartridge 003 has defects through the vibrating film 203, and can accurately and specifically determine whether the cartridge 003 has defects. Since the second film 203 will droop downwards under the action of its own gravity, if the second film 203 is in a drooping state before the second film 203 approaches the pickup 003, when the second film 203 approaches the pickup 003, the second film 203 cannot be above the pickup 003, and the above-mentioned defect of the pickup 003 cannot be detected by the vibration test of the second film 203; Therefore, in order to ensure that the film 203 can accurately fall on the upper surface of the cartridge 003, before the electric drive plate 201 away from the camera 13 moves the cartridge 003, the telescopic portion of the electric push rod 211 is controlled to drive the pressure plate 212 to move downward, pressing the root of the film 203 into the receiving groove 213a, so that the end of the film 203 can be tilted. When the electric drive plate 201 is close to the cartridge 003, the end of the film 203 will be above the cartridge 003. Subsequently, the telescopic portion of the electric push rod 211 is controlled to drive the pressure plate 212 to move upward and reset. After losing the downward pressure of the pressure plate 212, the root of the film 203 will pop out of the receiving groove 213a, so that the end of the film 203 will naturally droop under the action of gravity, and accurately fall on the upper surface of the cartridge 003.

[0029] It should be noted that when the film 203 is pressed downward by the pressure plate 212, the film 203 will stick to the inclined surfaces of the inclined portion 1 212a and the inclined portion 213b, so that the film 203 will be in an inclined state before it falls on the pickup 003, thereby restricting the falling direction of the film 203, giving the film 203 a basic falling direction, preventing the film 203 from curling toward the electric drive paddle 201, and ensuring that the film 203 can accurately fall on the pickup 003.

[0030] Example 3 On the basis of Example 2, Figure 2-5 As shown, the connecting plate 10 is hollow and is provided with an air inlet, which is communicated with an external pump.

[0031] The air inlet of the connecting plate 10 is provided with a filter screen, through which dust in the air is filtered to prevent dust in the air from entering the interior of the housing 2 along with the air flow and adhering to the surfaces of components such as the record 001 and the base 002, thereby affecting the test work.

[0032] The present invention specifically works as follows: After detecting that record 001 will not cause wrinkles in film 12, record 001 is placed on turntable 002a and central shaft 002b according to the steps in Example 1. Then, record 001 is controlled to rotate again following turntable 002a. At the same time, the external pump is controlled to blow air into slot 10a through the air inlet on connecting plate 10 and the hollow connecting plate 10 in sequence, so that film 12 floats irregularly under the disturbance of the air flow. At this time, record 001 and turntable 002 are observed through camera 13. By checking whether a can rotate normally and smoothly, we can infer whether record 001 and turntable 002a can operate normally and smoothly in the presence of debris. In this way, by simulating the problems encountered in the actual use scenarios of record 001 and turntable 002, and testing the actual use effects of components such as record 001 and turntable 002, we can conduct a comprehensive test on components such as record 001 and turntable 002 to ensure that components such as record 001 and turntable 002 can play music stably when they are actually used.
