Description

Technical Field

[0001] This utility model relates to the field of buzzer detection technology, specifically a buzzer rotation detection mechanism. Background Technology

[0002] A buzzer is an electronic sound-generating element made of piezoelectric ceramic material. It converts electrical energy into mechanical vibration through the inverse piezoelectric effect, thereby producing sound. Buzzers require strict testing during the production process.

[0003] Traditional buzzer testing institutions rely on manual handling to pick up and place buzzers one by one and transfer them between multiple independent testing devices to complete the testing. This results in extremely low testing efficiency. Furthermore, it requires manual visual identification of the front and back of the buzzer, which is easily affected by factors such as operator fatigue and workshop lighting conditions, leading to frequent misjudgments. Consequently, unqualified buzzers flow into subsequent assembly processes, causing subsequent quality problems.

[0004] Therefore, we urgently need a buzzer plate rotation detection mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a buzzer plate rotation detection mechanism to solve the problems mentioned in the background art. Traditional buzzer plate detection mechanisms rely on manual handling to pick up and place buzzer plates one by one and transfer them between multiple independent detection devices to complete the detection. This results in extremely low detection efficiency. Furthermore, it requires manual visual identification of the front and back of the buzzer plate, which is easily affected by factors such as operator fatigue and workshop lighting conditions, leading to frequent misjudgments. Consequently, unqualified buzzer plates flow into subsequent assembly processes, causing subsequent quality problems.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a buzzer plate rotation detection mechanism, including a frame and a buzzer material tray, wherein the inner side of the frame is provided with a suction and handling component, a rotation detection component, a visual differentiation component and a sorting and storage component;

[0007] The suction and transport assembly includes a first front and rear module, and a first upper and lower module is slidably connected to the outside of the first front and rear module. A first vacuum suction pen is installed at one end of the first upper and lower module, and a pneumatic vibrator is installed at one end of the first vacuum suction pen.

[0008] The rotating testing assembly includes a vacuum rotating platform. The vacuum rotating platform is externally equipped with a polarization testing station, a capacitance testing station, a performance testing station, and an insulation testing station. Each of the polarization testing station, capacitance testing station, performance testing station, and insulation testing station is externally equipped with a testing cylinder. The output end of each testing cylinder is fixedly connected to an upper and lower ejector pin.

[0009] The visual discrimination component includes an industrial camera, which is fixedly connected to the inside of the frame and corresponds to the unloading station of the vacuum rotary platform.

[0010] The sorting and storage assembly includes a transport module and a buzzer lifting module. A second upper and lower module is slidably connected to the outside of the transport module. A second vacuum suction pen is installed at one end of the second upper and lower module. A jig frame is provided on the top of the buzzer lifting module. A front jig is installed at one end of the jig frame. A rotary cylinder is installed on the outside of the jig frame. A back jig is fixedly connected to the output end of the rotary cylinder. A waste box is installed at one end of the buzzer lifting module.

[0011] Preferably, the first front and rear modules and the conveying module include a drive motor, the output end of which is fixedly connected to a lead screw, and the lead screw is externally threaded with a sliding block.

[0012] Preferably, the first upper and lower modules and the second upper and lower modules include a drive cylinder, and the bottom of the drive cylinder is fixedly connected to a mounting bracket.

[0013] Preferably, a lifting plate is provided at one end of the buzzer lifting module, and a lifting rod is fixedly connected to the top of the lifting plate.

[0014] Preferably, a buzzer tube is provided on the inner side of the front fixture, and one end of the conveying module is fixedly connected to one end of the frame.

[0015] Preferably, a rotary motor is installed at the bottom of the vacuum rotary platform.

[0016] Preferably, there are multiple first vacuum suction pens and multiple second vacuum suction pens, and all first vacuum suction pens and multiple second vacuum suction pens are arranged in a linear array.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] Firstly, this utility model places the tooling plate for holding the buzzer into the buzzer material tray. The first front and rear modules and the first upper and lower modules of the suction and handling component, together with the first vacuum suction pen, automatically pick up and transfer the buzzer. During the process, the pneumatic vibrator can also adjust the posture of the buzzer to ensure neatness. The vacuum rotation platform of the rotating detection component drives the buzzer to pass through the polarization detection station, capacitance detection station, performance detection station, and insulation detection station in sequence to complete multiple tests without manual transfer. The industrial camera of the visual differentiation component automatically identifies the front and back of the buzzer. The sorting and storage component automatically throws the unqualified buzzer into the waste box and stores the reversed buzzer after it is flipped by the rotary cylinder. The entire process only requires manual replacement of the buzzer tube after it is full, effectively avoiding errors caused by human visual fatigue or movement deviation, reducing labor costs and improving the stability of the detection process.

[0019] Secondly, this utility model uses a vacuum rotation platform of the rotating detection component to drive the buzzer to simultaneously complete polarization, capacitance, performance, and insulation tests, eliminating the need to transfer the buzzer back and forth between different testing devices. This enables continuous testing of multiple items. Furthermore, both the first vacuum suction pen of the suction and handling component and the second vacuum suction pen of the sorting and storage component are designed with multiple suction pens arranged in a linear array, which can pick up multiple buzzers at a time, reducing the number of reciprocating transfers. Combined with the rapid response of components such as the drive cylinder, this improves the testing efficiency. Attached Figure Description

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A buzzer plate rotation detection mechanism includes a frame 1 and a buzzer material tray 11. The inner side of the frame 1 is provided with a suction and handling component 2, a rotation detection component 3, a vision differentiation component 4 and a sorting and storage component 5.

[0030] The suction and handling assembly 2 includes a first front and rear module 21, and a first upper and lower module 22 is slidably connected to the outside of the first front and rear module 21. A first vacuum suction pen 23 is installed at one end of the first upper and lower module 22, and a pneumatic vibrator 24 is installed at one end of the first vacuum suction pen 23.

[0031] The rotating testing assembly 3 includes a vacuum rotating platform 31. The vacuum rotating platform 31 is externally provided with a polarization testing station 32, a capacitance testing station 33, a performance testing station 34, and an insulation testing station 35. Each of the polarization testing station 32, capacitance testing station 33, performance testing station 34, and insulation testing station 35 is externally provided with a testing cylinder 36. The output end of the testing cylinder 36 is fixedly connected to an upper and lower ejector pin 37.

[0032] The visual differentiation component 4 includes an industrial camera 41, which is fixedly connected to the inside of the frame 1 and corresponds to the unloading station of the vacuum rotary platform 31.

[0033] The sorting and storage assembly 5 includes a transport module 51 and a buzzer lifting module 52. A second upper and lower module 53 is slidably connected to the outside of the transport module 51. A second vacuum pen 54 is installed at one end of the second upper and lower module 53. A jig frame 55 is provided on the top of the buzzer lifting module 52. A front jig 56 is installed at one end of the jig frame 55. A rotary cylinder 57 is installed on the outside of the jig frame 55. A back jig 58 is fixedly connected to the output end of the rotary cylinder 57. A waste box 59 is installed at one end of the buzzer lifting module 52.

[0034] Specifically, the first front and rear module 21 and the transport module 51 include a drive motor, the output end of which is fixedly connected to a lead screw 12, and the lead screw 12 is externally threaded to a sliding block 13.

[0035] Specifically, the first upper and lower modules 22 and the second upper and lower modules 53 include a drive cylinder 14, and a mounting bracket 15 is fixedly connected to the bottom of the drive cylinder 14.

[0036] Specifically, a lifting plate 501 is provided at one end of the buzzer lifting module 52, and a lifting rod 502 is fixedly connected to the top of the lifting plate 501.

[0037] Specifically, a buzzer tube is provided on the inner side of the front fixture 56, and one end of the transport module 51 is fixedly connected to one end of the frame 1.

[0038] Specifically, a rotary motor is installed at the bottom of the vacuum rotary platform 31.

[0039] Specifically, multiple first vacuum suction pens 23 and second vacuum suction pens 54 are provided, and all first vacuum suction pens 23 and second vacuum suction pens 54 are arranged in a linear array.

[0040] Its working principle is as follows: First, the tooling plate with the buzzer chip placed on it is placed in the buzzer material tray 11. The suction and handling component 2 starts to operate, and the drive motor drives the lead screw 12 to rotate, thereby driving the sliding block 13 to move. In turn, the first front and rear module 21 connected to the sliding block 13 moves along the preset trajectory inside the frame 1 to the top of the buzzer material tray 11. Then, the drive cylinder 14 drives the mounting frame 15 to descend, so that the first vacuum suction pen 23 installed at one end contacts the buzzer chip and completes the suction. At the same time, the pneumatic vibrator 24 installed at one end of the first vacuum suction pen 23 starts, and adjusts the attitude of the buzzer chip by slight vibration to ensure that the buzzer chip is stably adsorbed and in a regular position. Then, the first upper and lower module 22 rises, and the first front and rear module 21 drives the buzzer chip to rotate. On the vacuum rotary platform 31 of the testing component 3, a rotary motor drives the vacuum rotary platform 31 to rotate at a constant speed, sequentially conveying the buzzer to the externally set polarization testing station 32, capacitance testing station 33, performance testing station 34, and insulation testing station 35. At each testing station, the external testing cylinder 36 synchronously extends and retracts, driving the upper and lower ejector pins 37 fixedly connected to the output end to contact the buzzer electrode, respectively completing the testing of the buzzer's polarization performance, capacitance value, electroacoustic performance, and insulation performance. After testing, the vacuum rotary platform 31 conveys the buzzer to the unloading station. The industrial camera 41 of the visual differentiation component 4, fixed inside the frame 1 and corresponding to the unloading station, photographs the buzzer, quickly identifying and distinguishing the front and back of the buzzer. The sorting and storage assembly 5 is activated: the drive motor at the conveying module 51 drives the lead screw 12 to rotate, causing the sliding block 13 to move, which in turn moves the second upper and lower module 53 to the unloading station. The drive cylinder 14 at the second upper and lower module 53 drives the mounting frame 15 to descend, so that the second vacuum suction pen 54 installed at one end picks up the buzzer after testing. If the buzzer fails the test, the conveying module 51 and the second upper and lower module 53 work together to transport it to the waste box 59 installed at one end of the buzzer lifting module 52 and discard it. If the buzzer passes the test and is front-facing, it is transported to the front fixture 56 installed at one end of the fixture frame 55 at the top of the buzzer lifting module 52. If it is back-facing, it is transported to the reverse side of the external rotary cylinder 57 fixedly connected to the output end of the external rotary cylinder 57 of the fixture frame 55. Inside the face fixture 58, the rotary cylinder 57 is activated, causing the reverse fixture 58 to rotate 180 degrees, flipping the reverse buzzer chip and transferring it into the front fixture 56. Simultaneously, the buzzer chip lifting module 52 slowly adjusts the height of the lifting plate 501 and lifting rod 502 according to the stacking height of the buzzer chips in the front fixture 56. The lifting rod 502 corresponds to the buzzer chip tube at the front fixture 56, thus ensuring that the buzzer chips can be orderly installed into the storage structure within the front fixture 56. After the buzzer chip tube is full, it is manually removed and replaced with an empty buzzer chip tube. This completes the fully automated operation of the buzzer chip process, from feeding, handling, multi-item simultaneous detection, front and back separation to qualified sorting and storage, effectively reducing manual intervention and minimizing errors caused by manual operation.This significantly improves the efficiency and accuracy of buzzer chip testing, while preventing substandard buzzers from entering subsequent processes, thus ensuring the quality of buzzer chip products.
