Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0050] In the related art, the buzzer 1300 has the characteristics of small size, high sensitivity, low power consumption, good reliability, low cost and good frequency characteristics. Since the buzzer 1300 has a simple structure, stable quality and low price, it has a large market application and is widely used as a sound device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers, etc.

[0051] In order to ensure the stable performance of the buzzer 1300, it is necessary to perform a quality inspection process on each buzzer 1300 after it is assembled, in order to screen out the buzzers 1300 that do not meet the quality standards; wherein the quality inspection process includes the process of inspecting the electrical performance parameters and the sound performance parameters of the buzzer 1300, wherein the electrical performance parameters include the audio frequency and decibel, and the sound performance parameters include the resistance and current;

[0052] In the related art, most of the methods involve a worker holding the buzzer 1300 and manually taking the test probe of the electroacoustic tester to contact and connect with the pin 1310 of the buzzer 1300 to observe the display data of the electroacoustic tester to determine whether the buzzer 1300 is qualified; or, using a function signal generator, a multimeter and a decibel meter to perform resistance, current, audio and decibel tests on the buzzer 1300 respectively; however, no matter which method is used, manual operation is required, which is time-consuming and labor-intensive, and the detection efficiency is low.

[0053] like Figure 1 and Figure 2 As shown, in order to solve the above technical problems, the preferred embodiment provided by the present invention provides a buzzer testing device, including a movable body 100 and arranged on the movable body 100: a first detection member 1100, a first driving member 600, a first placement member and a limit member, the first detection member 1100 has a movable connecting terminal 1110, and the first detection member 1100 can detect the parameters of the buzzer 1300; the first driving member 600 is connected to the connecting terminal 1110, and the first driving member 600 can drive the connecting terminal 1110 to move along a set path; and, the first placement member has a first detection position 400 for placing the buzzer 1300; and, the limit member is installed on the first placement member, and the limit member can limit the posture of the buzzer 1300 located at the first detection position 400, so that the pin 1310 of the buzzer 1300 can be at least partially exposed to the set path.

[0054] The first detection component 1100 is an existing device for detecting the existing buzzer 1300, for example, it can be an electroacoustic tester, or it can be one or more of a function signal generator, a multimeter and a decibel meter. No specific limitation is made here, as long as it can detect the target parameters of the buzzer 1300; optionally, it can simply measure one or more of resistance, current, audio and decibel, which can be set according to actual production needs.

[0055] It should be noted that the first detection member 1100 has a connecting terminal 1110, which is a probe, and is connected to the first detection member 1100 via a flexible cable, similar to the connection between the plug board and the plug via a flexible cable, to ensure that the connecting terminal 1110 can move freely, and how to set it is common knowledge in the field and does not pose a technical problem to technicians in the field.

[0056] Obviously, the first driving member 600 is used to drive the connecting terminal 1110 to move along the set path so as to approach or move away from the pin 1310 of the buzzer 1300 located on the set path, thereby controlling the connection and separation between the connecting terminal 1110 and the pin 1310, that is, the corresponding buzzer 1300 is connected to the first detection member 1100 for detection, or after the detection is completed, the buzzer 1300 is separated from the first detection member 1100; in addition, there is no need to limit the moving direction (that is, the set path) of the first driving member 600 to drive the connecting terminal 1110, as long as the connecting terminal 1110 can be driven close to or away from the pin 1310 to achieve the connection or disconnection of the first detection member 1100 That is to say, it can be set as follows: the first driving member 600 drives the connection terminal 1110 to move up and down, so as to be able to connect or disconnect the pin 1310 located below the connection terminal 1110. At this time, the pin 1310 of the buzzer 1300 is kept facing upward, and the connection terminal 1110 is set downward, so that the connection terminal 1110 and the pin 1310 can be connected. It can also be set as follows: the first driving member 600 drives the connection terminal 1110 to move horizontally, and similarly, the connection terminal 1110 can be connected to or disconnected from the pin 1310. At this time, the pin 1310 of the buzzer 1300 is kept facing the connection end, so that the connection terminal 1110 and the pin 1310 can be connected.

[0057] Optionally, no matter which method is adopted, a limiter can be set at the first detection position 400 to limit the buzzer 1300 and ensure that the pin 1310 can accurately dock with the connecting terminal 1110. The limiter can be a limit hole, so that the end of the buzzer 1300 away from the connecting terminal 1110 can be placed in the limit hole, and a clearance fit is set between the buzzer 1300 and the limit hole; the limiter can also be set as a clamping mechanism, which is not specifically limited here. As long as the posture of the buzzer 1300 placed at the first detection position 400 can be limited to prevent it from shaking, it can ensure that each buzzer 1300 placed or moved at the first detection position 400 can maintain the same posture (that is, keep the pin 1310 in the same position to ensure that the pin 1310 is in the set path), so that the connecting terminal 1110 can accurately dock with the pin 1310 of the buzzer 1300 when it moves along the set path.

[0058] The connecting terminal 1110 can be a test conductive probe. Furthermore, in order to facilitate the connection between the connecting terminal 1110 and the pin 1310, the test probe can be set to have an axially extending socket so that the pin 1310 can be inserted into the socket when docking the pin 1310, thereby ensuring a stable connection between the two.

[0059] In addition, as is common knowledge in the art, the buzzer 1300 has a pair of pins 1310 , and correspondingly, the number of the connecting terminals 1110 is also set to a pair, and corresponds one-to-one with the pins 1310 , so that a closed loop can be formed after the connecting terminal 1110 is connected to the corresponding pin 1310 .

[0060] When the buzzer testing device provided by the present invention is used, the buzzer 1300 to be tested can be placed at the first testing position 400 by using a mechanical arm or manually, and the first driving member 600 is used to drive the connecting terminal 1110 of the first testing member 1100 to move toward the pin 1310, so as to achieve the docking of the two. Subsequently, the buzzer 1300 can be tested by running the first testing member 1100 to determine the performance quality of the currently tested buzzer 1300. In specific operations, the test data of the first testing member 1100 can be read manually, or the corresponding parameter data can be collected by the first testing member 1100 and compared with the corresponding standard parameter data to automatically determine and produce the test results. Either method can complete the quality test of the buzzer 1300.

[0061] Therefore, the device can replace the manual connection between the buzzer 1300 and the first detection member 1100, saving time and labor, and can effectively improve the production and detection efficiency, especially in large-scale production.

[0062] like Figure 2 As shown, based on the above embodiment, the first detection component 1100 can detect the electrical performance parameters and / or sound performance parameters of the buzzer 1300; wherein the first detection component 1100 includes an electroacoustic tester.

[0063] It should be noted that the electrical performance parameters of the buzzer 1300 include audio and decibel, and the audio performance parameters include resistance and current, which are standard parameters for measuring the quality of the buzzer 1300 on the market, and it will not be repeated why these parameters are measured; in addition, other parameters besides resistance, current, audio and decibel can also be measured.

[0064] In addition, for better technical effect, the first detection member 1100 is selected as an electroacoustic tester, which is an existing device, and the principle and structure of the device are not described in detail; it should be noted that the electroacoustic tester can detect any one or more items of resistance, current, audio and decibel, and is more convenient to use; wherein, the connection terminal 1110 is an electrical signal interface (i.e., a wiring terminal) connected to the electroacoustic tester through a flexible cable;

[0065] In actual settings, the audio collection module of the electroacoustic tester may be arranged close to the first detection position 400 so as to improve the sound pickup quality.

[0066] like Figure 2 and Figure 3 As shown, based on the above embodiment, the buzzer 1300 testing device further includes a feeding piece, which is connected to the first object placement piece, and is used to transport the buzzers 1300 one by one to the first detection position 400.

[0067] That is, the buzzers 1300 to be inspected are transported one by one to the first inspection position 400 by a feeding piece to replace manual placement, further improving the level of automated inspection and reducing manual labor; optionally, the buzzer 1300 can be automatically picked up and placed by a robot in conjunction with a binocular camera.

[0068] like Figure 3 As shown, based on the above embodiment, the connecting terminal 1110 and the pin 1310 of the buzzer 1300 located at the first detection position 400 are arranged opposite to each other; wherein, the first driving member can drive the connecting terminal 1110 to move along the opposite direction between the connecting terminal 1110 and the pin 1310 of the buzzer 1300 located at the first detection position 400, so that the connecting terminal 1110 can be connected to or separated from the pin 1310.

[0069] Optionally, the first placement piece is located below the connecting terminal 1110, and the pin 1310 of the buzzer 1300 located at the first detection position 400 is facing upward; wherein, the first driving member 600 can drive the connecting terminal 1110 to rise and fall, so that the connecting terminal 1110 is connected to the pin 1310 of the buzzer 1300 located at the first detection position 400; specifically, the connecting terminal 1110 can be arranged to be opposite to the pin 1310 located at the first detection position 400, and then the connecting terminal 1110 can be connected to or separated from the pin 1310 only by the first driving member 600 driving the connecting terminal 1110 to rise and fall.

[0070] Of course, the pins of the buzzer 1300 may be arranged to be opposite to the connection terminal in the horizontal direction, or the pins 1310 of the buzzer 1110 may be arranged to be opposite to the connection terminal 1110 in the inclined direction. There is no specific limitation here, as long as the function can be achieved.

[0071] The first driving member 600 may be an electric push rod, or a vertically arranged linear moving module, or a pneumatic cylinder, or a hydraulic cylinder, etc., which are all common devices in the art, and their working principles or structures will not be described in detail here;

[0072] It should be noted that the first driving member 600 drives the connecting terminal 1110 to descend until the first detecting member 1100 obtains the parameters of the buzzer 1300 , which means that the connecting terminal 1110 moves into place, that is, the connecting terminal 1110 is connected to the pin 1310 .

[0073] like Figure 3 and Figure 5 As shown, in this embodiment, the feeding member includes: a vibrating feeding tray 200 and a straight vibration feeder 300, the straight vibration feeder 300 is connected to the vibrating feeding tray 200, the straight vibration feeder 300 is used to receive the buzzer 1300 discharged from the vibrating feeding tray 200, and transport it to the first detection position 400, and the first detection position 400 is set on the transport path of the straight vibration feeder 300;

[0074] The above-mentioned vibration feeder tray 200 is an existing device, which can adjust the posture of batches of buzzers 1300 to be tested one by one, so that their pins 1310 are facing upwards, and convey them to the first detection position 400 one by one; and the direct vibration feeder 300 is used to receive the buzzers 1300 after posture adjustment, and convey the buzzers 1300 one by one to the first detection position 400 at its end through its own vibration. Then, when the first detection position 400 contains the buzzer 1300 to be tested, the direct vibration feeder 300 stops vibrating and feeding, and then the buzzer 1300 at the first detection position 400 can be limited and fixed by the limit piece.

[0075] The above-mentioned limiting member can adjust the posture of the buzzer 1300 entering the first detection position 400 to ensure that each buzzer 1300 entering the first detection position 400 is in the same posture, so as to be able to accurately dock with the connecting terminal 1110.

[0076] In addition, if Figure 4 and Figure 5 As shown, the limiting member includes a limiting slide groove 1200 which is arranged above the direct vibration feeder 300 and extends along the conveying path of the direct vibration feeder 300. The pin 1310 of the buzzer 1300 can slide along the limiting slide groove 1200, and the limiting slide groove 1200 is configured to enable the pin 1310 of the buzzer 1300 entering the first detection position 400 to be guided to the set path.

[0077] Specifically, a guide plate is fixed at the upper end of the linear feeder, and a limiting slide groove 1200 is opened on the guide plate, wherein the pin 1310 of the buzzer 1300 transported by the straight vibration feeder 300 slides along the limiting slide groove 1200, and since the buzzer 1300 has a pair of pins 1310, the limitation of the limiting slide groove 1200 can ensure that the buzzer 1300 cannot rotate, that is, it can be achieved that the buzzers 1300 transported to the first detection position 400 are all controlled to be in the same posture.

[0078] Optionally, the limiting slide groove 1200 is installed above the direct vibration feeder 300, and both ends of the limiting slide groove 1200 are set as open structures; wherein, the end of the limiting slide groove 1200 close to the vibration feeding plate 200 is set to a flared shape to facilitate guiding the pin 1310 to enter the limiting slide groove 1200.

[0079] It should be noted that the width of the limiting slide groove 1200 is set to enable a pair of pins 1310 of the buzzer 1300 entering the first detection position 400 to be arranged in sequence along the length direction of the limiting slide groove 1200, that is, the connecting line between the pair of pins 1310 coincides with the length direction of the limiting slide groove 1200.

[0080] Specifically, the limiting slide groove 1200 can be set in two sections, the first section is set to a flared shape close to the vibrating feeding plate 200, the second section is of equal width at all places, and the second section is clearance-matched with the pin 1310, which can not only ensure the adjustment of the posture of a pair of pins 1310, but also ensure that the pin 1310 slides in the limiting slide groove 1200; it should be noted that the connection between the first section and the second section has a smooth transition.

[0081] It should be noted that if Figure 4 As shown, the pin 1310 of the buzzer 1300 faces upward, and the upper end of the pin 1310 extends out of the limiting sliding groove 1200 , thereby ensuring that the connecting terminal 1110 can contact the pin 1310 .

[0082] like Figure 4 As shown, based on the above embodiment, the buzzer 1300 testing device also includes: a position detection component 1400, the position detection component 1400 is electrically connected to the feeding component, the position detection component 1400 can detect whether the buzzer 1300 is present in the first detection position 400, and send a control instruction to the feeding component according to the detection result.

[0083] Optionally, the position detection member 1400 is installed on the first placement member, and can detect whether there is a buzzer 1300 to be detected at the first detection position 400, that is, to determine whether the buzzer 1300 conveyed by the feeding member has moved to the position; and the position detection member 1400, the first driving member 600 and the first detection member 1100 are electrically connected to each other through signal transmission, so that the three can be linked to each other, which is more intelligent; that is, when the position detection member 1400 detects that there is a buzzer 1300 to be detected at the first detection position 400, The position detection member 1400 sends a signal to the controller, and the controller analyzes the signal and sends a control instruction to the first driving member 600 and the first detection member 1100 according to the analysis result. The first driving member 600 drives the connecting terminal 1110 to move to connect the pin 1310, and then the first detection member 1100 starts to detect various performance parameters of the buzzer 1300; and when the first detection member 1100 completes the detection, the controller sends an instruction to the first driving member 600 to control the connecting terminal 1110 to disengage from the pin 1310.

[0084] Of course, the position detection member 1400 can be electrically connected to the feeding member through the controller, so that when the buzzer 1300 transported by the feeding member moves to the first detection position 400, the controller sends a control instruction to the feeding member to stop the feeding member.

[0085] In specific settings, the first driving member 600 and the first detecting member 1100 may also be operated manually after being prompted by the position detecting member 1400, which is not specifically limited here.

[0086] On the basis of the above-mentioned embodiment, the position detection component 1400 includes: an infrared detection sensor and a controller; wherein the infrared detection sensor is electrically connected to the feeding component through the controller.

[0087] The infrared detection sensor is used to determine whether there is a buzzer 1300 to be detected at the first detection position 400. During the specific installation, the infrared detection sensor can be installed on one side of the first detection position 400, and an infrared receiver can be set on the side opposite to it. If the light emitted by the infrared detection sensor is blocked for judgment, it means that there is a buzzer 1300 to be detected at the first detection position 400. If there is a buzzer 1300 to be detected, the infrared detection sensor transmits the signal to the controller, and the controller controls the start and stop of the feeding piece according to the received signal. The controller can be a PLC programmable controller.

[0088] Preferably, the infrared detection sensor can be electrically connected to the first driving member 600 and the first detection member 1100 through the controller, so that when the buzzer 1300 to be detected moves to the first detection position 400, the controller controls the first driving member 600 to drive the connecting terminal 1110 to move according to the signal transmitted by the infrared detection sensor, so that the connecting terminal 1110 is connected to the pin 1310, and the first detection member 1100 is started synchronously for automatic detection; obviously, the quality of the buzzer 1300 can also be automatically determined by the first detection member 1100. The data of the first detection member 1100 can be measured and graded to replace manual reading of the data of the first detection member 1100 and manual judgment; wherein, whether the connecting terminal 1110 has moved into place can be determined by whether the first detection member 1100 has collected the pin 1310, and when it is moved into place, the connecting terminal 1110 and the pin 1310 are in contact and connected; optionally, in other embodiments, the moving distance of the connecting terminal 1110 driven by the first driving member 600 can be set, for example, the lifting distance thereof can be set to achieve that the connecting terminal 1110 just contacts the pin 1310 when it descends the set distance.

[0089] It should be noted that the position detection element 1400 is not limited to an infrared detection sensor, but may also be a photoelectric sensor, a travel switch, or a Hall sensor, etc.

[0090] like Figure 4 and Figure 6 As shown, based on the above embodiment, the buzzer 1300 testing device also includes a second detection piece 700 and a second placement piece; wherein the second placement piece has a second detection position 500 for placing the buzzer 1300, and the second detection piece 700 can collect the appearance parameters of the buzzer 1300 located at the second detection position 500.

[0091] Specifically, the second detection member 700 is used to obtain an appearance image of the buzzer 1300 and compare it with a set standard appearance image to obtain an analysis result, thereby realizing detection of whether there is a defect in the appearance of the buzzer 1300 .

[0092] like Figure 6 As shown, based on the above embodiment, the second detection member 700 includes a plurality of cameras 810 installed on the second object placement member, and the plurality of cameras 810 are respectively used to obtain end image information and side image information of the buzzer 1300 located at the second detection position 500, and the plurality of cameras 810 are electrically connected to the controller.

[0093] Specifically, three cameras 810 can take pictures of the upper end, lower end and side of the buzzer 1300 to obtain the appearance of each part of the buzzer 1300, and realize its appearance detection; it should be noted that there is no need to limit the number of cameras 810, as long as the complete appearance of the buzzer 1300 can be obtained through the cooperation between the cameras 810; among them, the camera 810 can use a CCD camera, which adopts visual detection, and visual detection is to use a machine instead of the human eye to make measurements and judgments. Visual detection refers to the conversion of the captured target into an image signal through a machine vision product (i.e., an image capture device, divided into CMOS and CCD), which is transmitted to a dedicated image processing system, and converted into a digital signal according to pixel distribution and brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment action on site according to the results of the judgment. It is a valuable mechanism for production, assembly or packaging. It has immeasurable value in the function of detecting defects and preventing defective products from being delivered to consumers.

[0094] Among them, in order to ensure that images of the buzzer 1300 at various angles can be obtained, the second detection position 500 can be set to be composed of a plate of transparent material, so that the plate will not block the camera 810 from shooting the buzzer 1300; specifically, if the buzzer 1300 is placed vertically, multiple cameras 810 can be placed in the vertical plane to obtain images of the two ends and one side of the buzzer respectively; if the buzzer 1300 is placed horizontally, multiple cameras 810 can be placed in the horizontal plane to obtain images of the two ends and one side of the buzzer 1300 respectively; there is no specific restriction here, and the placement posture is set according to the actual production, and the installation position of the camera 810 is adjusted accordingly, as long as the appearance of the buzzer 1300 can be detected.

[0095] like Figure 3 As shown, for better technical effects, on the basis of the above embodiment, the buzzer 1300 testing device further includes a grading and sorting component, which can classify the buzzer 1300 according to the detection results of the first detection component 1100 and / or the second detection component 700;

[0096] Specifically, the grading and sorting component can compare the parameters collected by the first detection component 1100 and / or the second detection component 700 with the corresponding standard parameters, and can grade the buzzer 1300 according to the comparison result;

[0097] That is, the buzzers 1300 that have been tested can be classified by grading and sorting parts. The specific classification can be based on their sound performance parameters, electrical performance parameters, and appearance parameters, instead of manual sorting.

[0098] Optionally, if the grading and sorting part is used to classify the buzzer 1300 inspected by the first inspection part 1100, it can be divided into four types, namely qualified products, products with defective resistance / current, defective audio products, products with defective resistance / current but can make sound, and products with defective appearance.

[0099] If the grading and sorting part is used to classify the buzzers 1300 detected by the second detection part 700, they can be divided into two types, namely, qualified products and defective products.

[0100] If the grading and sorting parts are used to classify the buzzers 1300 that have been inspected by the first inspection part 1100 and the second inspection part 700 in sequence, they can be divided into five types, namely, qualified products, products with defective resistance / current, defective audio products, products with defective resistance / current but can make sound, and products with defective appearance.

[0101] like Figure 3As shown, on the basis of the above embodiment, the grading and sorting component further includes: a clamping component 900, which can clamp the buzzer 1300 located at the first detection position 400 and / or the second detection position 500; and a second driving component 800, which is connected to the clamping component 900 and can drive the clamping component 900 to move, thereby placing the buzzer 1300 in a classification container 1000 of a corresponding level;

[0102] That is, the clamping member 900 and the second driving member 800 and the controller, the clamping member 900 and the second driving member 800 are electrically connected to the controller respectively, and the controller and the first detection member 1100 and the second detection member 700 are electrically connected, and the controller is used to compare the parameters collected by the first detection member 1100 and / or the second detection member 700 with the corresponding standard parameters, and can grade the buzzer 1300 according to the comparison result; the clamping member 900 can clamp the buzzer 1300 located at the first detection position 400 and / or the second detection position 500; and the second driving member 800 is connected to the clamping member 900, and the second driving member 800 can drive the clamping member 900 to move, so as to place the buzzer 1300 in the classification container 1000 of the corresponding level.

[0103] In practical applications, it is also possible to manually determine which category the buzzer 1300 belongs to based on the parameters collected by the first detection member 1100 and the second detection member 700, and then manually control the second driving member 800 and the clamping member 900 to clamp the buzzer 1300 into the corresponding classification container 1000; similarly, the second driving member 800 can select any one of an electric push rod, a linear motion module, a pneumatic cylinder and a hydraulic cylinder.

[0104] As long as the clamping member 900 can clamp the buzzer 1300, its structure is not specifically limited here. For example, an electric two-finger clamp or a pneumatic two-finger clamp can be selected.

[0105] like Figure 6 As shown, the plurality of cameras 810 together form an appearance detection channel, and the buzzer 1300 clamped by the clamping member 900 can pass through the appearance detection channel, and the appearance detection channel constitutes the second detection position 500.

[0106] After the first detection member 1100 is tested, the connection terminal 1110 moves upward; at the same time, the clamping member 900 clamps the buzzer 1300 of the first detection position 400, and then the clamping member 900 retreats and passes through the second detection position 500 surrounded by the camera 810. The camera 810 takes pictures in time to obtain images for defect detection.

[0107] It should be noted that the shape detection channel is not a closed configuration, and at least a gap is provided between two adjacent cameras 810 to allow the clamping member 900 to pass through.

[0108] That is to say, the buzzer 1300 is clamped to the shape detection channel by the clamp 900, and the clamp 900 is kept clamping the buzzer 1300 when taking pictures. Therefore, in order to reduce the blocking area of ​​the buzzer 1300 by the clamp 900, an electric two-finger clamp or a pneumatic two-finger clamp can be selected.

[0109] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0110] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0111] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
