Technical Field

[0001] The present application relates to the field of detection technologies, and particularly to a buzzer detection device. Background Art

[0002] A buzzer is an integrated electronic device belonging to a sounder, and is often used as an electronic material for generating a sounding prompt tone or a warning tone in electronic product applications. For the determination of the sound volume or sound quality of a buzzer in an electronic product, it mainly depends on the intuitive judgment made by a tester after listening to the sound emitted by the buzzer with the ear, resulting in low detection accuracy and lack of objectivity. The buzzer is mainly loaded through a buzzer placement tape and is pre-fixed on the buzzer placement tape. The determination of the quality of large-scale tape-type buzzers mainly involves judging whether the volume, sound quality, and audio frequency meet the national or factory design requirements, and special large-scale detection instruments need to be used for detection in a special experimental environment. The detection process is complex, and large experimental equipment cannot meet the needs of testers for batch sample detection on the production line, random inspection in the finished product storage warehouse, customer random inspection, and quality determination of single-unit after-sales repair. It is also impossible to directly determine the quality of the buzzer through random sampling under the normal workshop environment, resulting in limitations in the detection of buzzers.

[0003] In the prior art, in the patent with the publication number CN204748004U (a buzzer automatic assembly and detection machine), it is proposed that the detection machine includes a frame, a turntable mechanism, and an electrical control cabinet. The turntable mechanism is arranged on the frame, and a servo grasping mechanism, a deburring mechanism, a molybdenum sheet feeding mechanism, an upper cover discharging mechanism, an upper cover grasping and feeding mechanism, and a bent foot mechanism are sequentially arranged around the turntable mechanism in the clockwise direction. The upper cover discharging mechanism includes an upper cover vibrating disk bin, an upper cover discharging port, and an upper cover assembling machine. The electrical control cabinet is arranged below the frame, and a PLC controller is arranged in the electrical control cabinet. The PLC controller is respectively connected to each mechanism.

[0004] The above prior art has the following disadvantages:

[0005] It is impossible to quickly detect the quality of the buzzer, the detection process is complex, the sampling detection requirement cannot be realized, the detection environment of the buzzer is limited, resulting in low detection efficiency of the buzzer. Summary of the Invention

[0054] Embodiment 1

[0055] For the determination of the sound volume or sound quality of buzzers in electronic products, it mainly relies on the intuitive judgment of testers by listening to the sounds emitted by the buzzers with their ears. The detection accuracy is low and lacks objectivity. Buzzers are mainly loaded through buzzer placement tapes and are pre-fixed on the buzzer placement tapes. The quality determination of large-scale tape-type buzzers mainly involves judging whether the volume, sound quality, and audio frequency meet the national or factory design requirements. It is necessary to use special large-scale detection instruments in a special experimental environment for detection. The detection process is complex, and large-scale experimental equipment cannot meet the needs of testers for batch sample detection on the production line, random inspection in the finished product storage warehouse, customer random inspection, and quality determination of single-unit after-sales repair. It is also impossible to directly determine the quality of buzzers through random sampling under the normal workshop environment, resulting in limitations in buzzer detection. The existing technology cannot quickly detect the quality of buzzers, the detection process is complex, the sampling detection requirements cannot be achieved, and the detection environment of buzzers is limited, resulting in low detection efficiency of buzzers.

[0056] In view of the above problems, the embodiment of the present application provides a buzzer detection device. The device has a simple structure, which is convenient for the miniaturization design of the device, is conducive to placing the device in various types of test environments for detection, improves the detection fluency of buzzers, enhances the flexibility of buzzer detection, broadens the detection application range, effectively improves the detection accuracy of buzzers, and improves the production quality of buzzers.

[0057] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0058] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the buzzer detection device shown in the embodiment of the present application includes:

[0059] A material guiding mechanism 1, a conductive brush rod 2, a detection device 3, and a sound source collector 4. The material guiding mechanism 1 includes a disc runner 11. There are N guiding pins 111 provided on the rim of the disc runner 11, where N>1. The material guiding mechanism 1 is used to guide the buzzer placement tape 5 to move. It can be understood that the N guiding pins 111 can be evenly distributed on the rim of the disc runner 11, that is, the rotation angles between adjacent guiding pins 111 are equal, or the rotation angles between adjacent guiding pins 111 are arranged in a geometric progression. The N guiding pins 111 can also be unevenly distributed on the rim of the disc runner 11. N is an integer greater than 1. Preferably, the value of N can be 5 and is evenly distributed on the rim of the disc runner 11. Thus, when the disc runner 11 of the material guiding mechanism 1 rotates, the guiding pins 111 cooperate with the tape holes 51 of the tape to drive the buzzer placement tape 5 to move at a constant speed, improving the stability during detection. In practical applications, the distribution method of the N guiding pins 111 on the rim and the value-taking method of N are diverse and need to be determined according to the actual application situation to adapt to the detection of different models of buzzers 52, and no unique limitation is made here.

[0060] The buzzer placement tape 5 includes tape holes 51 arranged along the length direction of the buzzer placement tape 5 and buzzers 52. The setting direction of the conductive brush rod 2 is perpendicular to the arrangement direction of the pins 521 of the buzzer 52. Thus, when the guiding pins 111 cooperate with the tape holes 51 to drive the buzzer 52 on the buzzer placement tape 5 to reach the position where the conductive brush rod 2 is located, the conductive brush rod 2 can come into contact with the pins 521 of the buzzer 52. Therefore, during the movement of the buzzer placement tape 5, the conductive brush rod 2 comes into contact with the pins 521 of each buzzer 52 in turn. Further, the conductive brush rod 2 is connected to the function signal generator 31 and the multimeter 32 of the detection device 3. The sound source collector 4 is connected to the decibel meter 33 of the detection device 3. The sound source collector 4 is used to collect the sound emitted by the buzzer 52. Thus, when the conductive brush rod 2 comes into contact with the pins 521 of the buzzer 52, the buzzer 52 can be powered on for detection. The function signal generator 31 and the multimeter 32 collect the electrical detection parameters of the buzzer 52. The electrical detection parameters include but are not limited to current values and frequency values. And the sound emitted by the buzzer 52 can be collected by the sound source collector 4 and transmitted to the decibel meter 33, so that the acoustic detection parameters of the buzzer 52 can be collected. The acoustic detection parameters include but are not limited to decibel values. Based on the completion of the electrical detection parameters and the acoustic detection parameters, the detection of the buzzer 52 is completed.

[0061] In the embodiments of the present application, the buzzer 52 can be a passive piezoelectric buzzer or other types of buzzers. The pin 521 of the buzzer 52 will be fixed in advance on the buzzer placement tape 5. The center distance between the tape holes 51 on the buzzer placement tape 5 of the same type is fixed. Therefore, in practical applications, there is no unique limitation on the type of the buzzer 52 and the type of the buzzer placement tape 5. It is only necessary to adjust the distribution mode of the guiding pins 111 according to the pin pitch of the buzzer 52 of each type and the center distance between the tape holes 51 of the buzzer placement tape 5 of each type.

[0062] The following beneficial effects can be seen from the above Embodiment 1:

[0063] In the buzzer detection device of the present application, there are a feeding mechanism, a conductive brush rod, a detection device, and a sound source collector. There are N guiding pins on the rim of the disc runner of the feeding mechanism. The feeding mechanism is used to guide the movement of the buzzer placement tape. The buzzer placement tape includes tape holes and buzzers arranged along the length direction of the buzzer placement tape. The setting direction of the conductive brush rod is perpendicular to the arrangement direction of the pins of the buzzer, so that when the feeding mechanism moves the buzzer placement tape, the conductive brush rod can contact the pins of each buzzer to be detected respectively. The conductive brush rod is connected to a function signal generator and a multimeter, and the sound source collector is connected to a decibel meter. Detection can be completed according to the data obtained from the function signal generator, the multimeter, and the decibel meter, so that each buzzer to be detected can be powered on and detected in turn. The device structure is simple, which is convenient for the miniaturization design of the device, is beneficial to placing the device in various types of test environments for detection, improves the detection fluency of the buzzer, improves the flexibility of buzzer detection, broadens the detection application range, and judges the quality of the buzzer through the detection data, avoiding the low detection accuracy and lack of objectivity caused by relying on the ears of the detection personnel to make an intuitive judgment after hearing the sound emitted by the buzzer, improving the detection accuracy, and improving the production quality of the buzzer.

[0064] Embodiment 2

[0065] For the convenience of understanding, the following provides an embodiment of the buzzer detection device for illustration. In practical applications, an installation keel bracket will be installed to provide installation positions for each component in this device, improve the stability of this device, and can reasonably arrange the installation positions of each component, which is beneficial to the miniaturization of this device and is convenient for application in various test environments, expanding the application range; further designs will also be made on the guiding pins and the conductive brush rod to improve the detection effect and detection stability of the buzzer.

[0066] Please refer to Figures 1 to 6 , the second embodiment of the buzzer detection device shown in the embodiments of the present application includes:

[0067] The buzzer detection device further includes: a mounting keel bracket 6, the mounting keel bracket 6 includes a bracket base 61, a bracket top surface 62, and a bracket support surface 63, and the bracket support surface 63 is disposed between the bracket top surface 62 and the bracket base 61.

[0068] The material guiding mechanism 1 further includes a driving motor 12, the driving motor 12 and the detection device 3 are mounted on the bracket base 61 and are respectively located on both sides of the bracket support surface 63. It can be understood that the driving motor 12 is used to drive the disc runner 11 to rotate.

[0069] As Figure 4 shown, among the N guiding pins 111, a guiding cone 112 is provided at one end of the guiding pin 111 away from the center of the disc runner 11. The guiding cone includes a penetrating surface 1121 and a connecting surface 1122. The connecting surface 1122 is connected to the guiding pin 111, and the area gradually decreases along the direction from the connecting surface 1122 to the penetrating surface 1121. The area of the connecting surface 1122 is larger than the area of the tape hole 51, and the area of the penetrating surface 1121 is smaller than the area of the tape hole 51. The distance between the penetrating surface 1121 and the connecting surface 1122 is less than or equal to the hole depth of the tape hole 51.

[0070] It can be understood that the penetrating surface 1121 can enter the inside of the tape hole 51. Since the area of the connecting surface 1122 is larger than the area of the tape hole 51, the connecting surface 1122 will be exposed outside the tape hole 51. Therefore, during the rotation of the disc runner 11, when the guiding cone 112 of the guiding pin 111 rotates to the buzzer placement tape 5, the guiding cone 112 will insert into the current tape hole 51, driving the current tape hole 51 to move, thereby driving the buzzer placement tape 5 to move. As the disc runner 11 continues to rotate, the guiding cone 112 will gradually deviate from the buzzer placement tape 5, so that the guiding cone 112 will be withdrawn from the current tape hole 51. At this time, the next guiding pin 111 will also rotate to the buzzer placement tape 5 and insert into the next tape hole 51 of the current tape hole 51, continuing to drive the buzzer placement tape 5 to move. Therefore, the buzzer placement tape 5 can move with the rotation of the disc runner 11. The connecting surface 1122 being exposed outside the tape hole 51 can also prevent the situation where the guiding pin 111 is difficult to be withdrawn from the tape hole 51, improving the smoothness of the movement of the buzzer placement tape 5.

[0071] On the other hand, a taping limiting block 631 and a conductive brush rod 2 are provided on one side of the bracket support surface 63 close to the drive motor 12. The conductive brush rod 2 includes a conductive end portion and a conductive support rod. The distance between the conductive end portion and the bracket support surface 63 is equal to the distance by which the taping limiting block 631 protrudes from the bracket support surface 63, so that the guiding pin 111 can cooperate with the protruding end portion of the taping limiting block 631 away from the bracket support surface 63 to fix the position of the buzzer placing tape 5 on the plane where the conductive end portion is located, playing a supporting role for the buzzer placing tape 5 and preventing the buzzer placing tape 5 from deforming or wrinkling during movement, resulting in poor contact between the lead 521 of the buzzer 52 on the buzzer placing tape 5 and the conductive brush rod 2, leading to a decrease in detection efficiency. At the same time, since the area of the connecting surface 1122 of the guiding conical body 112 is larger than the area of the taping hole 51, and the area of the penetrating surface 1121 is smaller than the area of the taping hole 51, and the distance between the penetrating surface 1121 and the connecting surface 1122 is less than or equal to the hole depth of the taping hole 51, when the guiding conical body 112 presses the buzzer placing tape 5 on the protruding end portion of the bracket support surface 63, the penetrating surface 1121 will not scrape the protruding end portion, but can ensure that the position of the buzzer placing tape 5 is fixed on the plane where the conductive end portion is located, ensuring contact between the lead 521 of the buzzer 52 and the conductive brush rod 2.

[0072] Furthermore, the arc length distance between the penetrating surfaces 1121 of adjacent guiding pins 111 is M times the center distance between adjacent taping holes 51 on the buzzer placing tape 5, where M is greater than zero. Among them, this arc is concentric with the disk runner 11, so that when the disk runner 11 rotates, the guiding pin 111 can cooperate with the taping hole 51 to drive the buzzer placing tape 5 to move. It can be understood that the value of M can be determined according to the number of taping holes 51 occupied by the width between the leads 521 of the buzzer 52. The wider the width between the leads 521, the more taping holes 51 are occupied. Therefore, this arc length distance needs to be one time, two times or three times the center distance between adjacent taping holes 51 to complete the position movement between the buzzers 52 to be detected. Therefore, the value of M needs to be determined according to the actual application situation. The purpose is that after the guiding pin 111 rotates through the arc length distance, the currently detected buzzer 52 can be removed, and the next buzzer 52 can reach the position where the conductive brush rod 2 is located to complete the power-on detection. The value of M is not uniquely limited.

[0073] Furthermore, the conductive end of the conductive brush rod 2 includes a positive copper brush 21 and a negative copper brush 22. The conductive support rod of the conductive brush rod 2 includes a positive support rod and a negative support rod. The positive copper brush 21 is connected to the positive support rod, and the negative copper brush 22 is connected to the negative support rod. Among them, the positive support rod includes a first support rod 23 and a second support rod 24, and the negative support rod includes a third support rod 25 and a fourth support rod 26. A first spring 27 is provided on the outer periphery of the first support rod 23. Both ends of the first spring 27 are respectively in contact with the positive copper brush 21 and the bracket support surface 63. A second spring 28 is provided on the outer periphery of the fourth support rod 26. Both ends of the second spring 28 are respectively in contact with the negative copper brush 22 and the bracket support surface 63. The first support rod 23 and the third support rod 25 are parallel in the vertical direction, and the second support rod 24 and the fourth support rod 26 are parallel in the vertical direction. It can be understood that the first support rod 23 and the fourth support rod 26 provided with springs are not in the same vertical plane. The conductive end has an arc side surface and a connection side surface. The arc side surface is used to contact the pin 521 of the buzzer 52. Since there are two pins 521, one of the pins will squeeze the first spring 27 on the outer periphery of the first support rod 23, and the other pin will squeeze the first spring 28 on the outer periphery of the fourth support rod, so that the pin 521 is not rigidly connected to the conductive end, preventing the pin 521 from being damaged during the detection process. The connection side surface is used to connect to the conductive support rod.

[0074] The following beneficial effects can be seen from the second embodiment above:

[0075] When the driving motor of the material guiding mechanism drives the disc runner to rotate, the guiding conical body on the guiding pin can be inserted into the tape holes, driving the movement of the tape with the buzzer placed, so as to drive the buzzer to move to the position where the conductive brush rod is located for power-on detection, and as the disc runner continues to rotate, drive the buzzer to move out from the position where the conductive brush rod is located, and move the next buzzer to be detected to the position where the conductive brush rod is located for power-on detection. Furthermore, it can improve the smoothness of batch detection of buzzer quality, improve the detection flexibility of the buzzer. The setting of the installation keel bracket can reasonably arrange the installation positions of each component, which is beneficial to the miniaturization of the device, convenient for application in various test environments, expanding the application range, improving the device stability, thus improving the detection accuracy and the production quality of the buzzer.

[0076] Embodiment 3

[0077] For the convenience of understanding, an embodiment of the buzzer detection device is provided below for illustration. In actual application, an equipment protection chamber will be set up to protect the detection equipment. At the same time, the equipment protection chamber and the sound source collector are integrated onto the installation keel bracket to further optimize the structure of the device, and it can enable the sound source collector to fully collect the sound source of the buzzer, improving the detection accuracy.

[0078] Please refer to Figures 1 to 8 , Embodiment 3 of the buzzer detection device shown in the embodiments of the present application includes:

[0079] There are wire through-holes on the support surface 63 of the bracket. The wire through-holes include a first through-hole and a second through-hole. On the side of the support surface 63 of the bracket close to the detection device 3, there is an equipment protection chamber 34. The detection device 3 is arranged inside the equipment protection chamber 34. There is a control button 35 on the wall of the equipment protection chamber 34. The control button 35 is used to control the start and stop of the detection device 3. The detection device 3 has a first connection line 36 and a second connection line 37. The first connection line 36 passes through the equipment protection chamber 34 and is connected to the first through-hole, and is electrically connected to the positive copper brush 21. It can be understood that the first connection line 36 connected to the first through-hole can be electrically connected to the positive support rod, and the material of the positive support rod is also a conductive material, which can be the same as or different from the material of the positive copper brush 21, and is not uniquely limited; correspondingly, the second connection line 37 passes through the equipment protection chamber 34 and is connected to the second through-hole, and is electrically connected to the negative copper brush 22. The second connection line 37 connected to the second through-hole can be electrically connected to the negative support rod, and the material of the negative support rod is also a conductive material, which can be the same as or different from the material of the negative copper brush 22, and is not uniquely limited, so as to realize the conduction function.

[0080] As Figure 8 shown, the function signal generator 31 supplies power to the buzzer 52. After the buzzer 52 is powered on, the function signal generator 31 and the multimeter 32 can collect the electrical detection parameters when the buzzer 52 is powered on. At the same time, the sound emitted by the buzzer 52 after being powered on can be collected by the sound source collector 4 and transmitted to the decibel meter 33, so as to obtain the acoustic detection parameters.

[0081] As Figure 2 shown, the multimeter 32 and the decibel meter 33 are arranged above the function signal generator 31. It can be understood that in practical applications, the positional relationship among the function signal generator 31, the multimeter 32 and the decibel meter 33 is diverse, and a suitable positional relationship needs to be determined according to the actual application situation, which is not uniquely limited here.

[0082] As Figure 7 shown, there is a support groove 621 in the top surface 62 of the bracket. There is a guiding gap 6211 at the bottom of the support groove 621. The sound source collector 4 is arranged in the support groove 621. There is a collector support block 41 on the outer periphery of the sound source collection end. The collector support block 41 abuts against the bottom of the support groove 621 to support the sound source collector 4. In the embodiments of the present application, the sound source collector 4 can be a collection cover or a sound collection instrument, which is not uniquely limited here.

[0083] The sound source collection end of the sound source collector 4 faces the guiding slit 6211. Guiding rollers 6212 are provided on the two sidewalls of the guiding slit 6211. The distance between the opposite guiding rollers 6212 is equal to the diameter of the sounding end of the buzzer 52. That is, the sounding end of the buzzer 52 is arranged within the guiding slit 6211. Moreover, during the process of the tape for placing the buzzer 5 driving the buzzer 52 to move, the guiding rollers 6212 can play a role in increasing the smoothness of the movement. It can be understood that the sound source collection end of the sound source collector 4 facing the guiding slit 6211 can fully collect the sound emitted when the buzzer 52 is powered on, which is beneficial to improving the detection accuracy of the buzzer.

[0084] The detection device 3 also has a third connecting wire 38. The third connecting wire 38 is the connecting wire of the decibel meter 33. The third connecting wire 38 is connected to the sound source collector 4. The sound collected by the sound source collector 4 will be transmitted to the decibel meter 33, generating acoustic detection parameters including but not limited to decibel values.

[0085] The following beneficial effects can be seen from the above Embodiment 3:

[0086] By setting up the device protection bin to protect the detection device, the reliability of the device is improved. At the same time, integrating the device protection bin and the sound source collector onto the installation keel bracket further optimizes the structure of the present device, which is beneficial to the miniaturization of the device, enables use in different test environments, and can enable the sound source collector to fully collect the sound source of the buzzer, improving the detection accuracy.
