In addition, two loading stations are provided in the moving direction of the positioning seat 1, which are respectively used to place the microphone housing into the positioning seat 1 and place the upper cover with a PCBA into the opening of the microphone housing on the positioning seat 1. The distances of the above stations are the same.

[0035] The positioning seat conveying device can be a chain drive or belt drive structure driven by a motor. The positioning seat 1 is fixed on the chain or belt and is evenly arranged along its circumference according to design requirements.

[0036] See attached Figure 2 The positioning seat 1 is provided with a positioning cavity 1-1 for positioning the microphone housing, detection grooves 1-2 located on both sides of the positioning cavity 1-1, and a detection hole 1-3 located at the bottom of the positioning cavity 1-1. Photoelectric sensors are arranged on both sides of the detection groove 1-2 to detect the position of the positioning seat 1; photoelectric sensors are arranged on the upper and lower sides of the detection hole 1-3 to detect whether there is a microphone in the positioning cavity 1-1 during microphone detection and pin detection.

[0037] The positioning seat 1 is also provided with a positioning groove 1-4 that communicates with the positioning cavity 1-1. When pasting the EVA pad and the dust net, the microphone shell needs to be accurately positioned for accurate pasting. Therefore, a positioning device is also provided at these two stations. The positioning device includes a positioning cylinder 11 and a silicone block 10 fixed to the driving end of the positioning cylinder. The end of the silicone block 10 is provided with a groove that fits the corner of the microphone housing. When positioning is required, the cylinder drives the silicone block 10 to pass through the positioning groove 1-4 and contact the microphone housing to position the microphone housing in the positioning cavity 1-1.

[0038] At the first loading station, the microphone housing is manually placed in the positioning cavity 1-1. Then the positioning seat 1 moves to the EVA pad pasting station.

[0039] See attached Figure 3 and 4The above-mentioned EVA pad pasting device 100 includes an EVA pad adsorption head 101, an EVA pad pasting cylinder 102 that drives the EVA pad adsorption head 101 to adsorb and paste the EVA pad to the microphone housing, an X-axis electric slide 103 that drives the EVA pad pasting cylinder 102 to move left and right, and a Y-axis electric slide 104 that drives the X-axis electric slide 103 to move forward and backward.

[0040] Since the EVA pad is annular, adsorption holes are arranged in an annular array at the end of the EVA pad adsorption head 101 to facilitate adsorption of the EVA pad by negative pressure.

[0041] One end of the X-axis electric slide 103 is connected to the driving end of the Y-axis electric slide 104, and the other end is connected to the frame of the EVA pad pasting device. A Y-axis guide assembly is provided. The Y-axis guide assembly includes a Y-axis guide rail fixed on the frame and a Y-axis slider fixed on the X-axis driving device and matched with the Y-axis guide rail.

[0042] A connecting plate 105 is provided at the driving end of the X-axis electric slide 103, and a first camera 106 for detecting the position of the microphone housing is provided on the connecting plate 105, and an EVA pad pasting cylinder 102 is fixed to the bottom of the connecting plate 105. In this embodiment, there are two silicon microphones on one PCBA, so two EVA pads need to be pasted, so two groups of EVA pad pasting cylinders 102 and EVA pad adsorption heads 101 are arranged side by side on the connecting plate 105. When adsorbing EVA pads, two can be adsorbed at the same time, or they can be adsorbed one at a time in batches; when pasting, the pasting is achieved by simultaneous action.

[0043] A first camera 106 is provided on the connecting plate 105 for detecting the position of the microphone housing and detecting whether the EVA pad is pasted on the microphone housing to provide image data to the controller. The microphone housing in the positioning seat 1 can be positioned by moving the connecting plate 105 or the EVA pad pasting cylinder 102 in the plane to determine the position of the microphone housing and accurately paste the EVA pad on the microphone housing.

[0044] A second camera 107 is provided on the frame of the EVA pad pasting device 100 for collecting the quantity and position information of the EVA pads on the receiving plate 7 in the feeding device.

[0045] See attached Figure 5 After the EVA pad is pasted inside the microphone housing, the positioning seat 1 moves to the second loading station, and the operator places the upper cover with PCBA on the pressing part of the microphone housing. Then the positioning seat 1 moves to the pressing station. Under the action of the pressing device 200, the upper cover is pressed onto the microphone housing to form a microphone.

[0046] The above-mentioned pressing device 200 includes a pressing plate 201 and a pressing driving assembly 202 for driving the pressing plate 201 to rise and fall. The pressing driving assembly 202 can be a screw-nut structure driven by a motor, and the pressing is achieved by the downward movement of its driving end. A pressure sensor is also provided between its driving end and the pressing plate 201 to detect the pressing force, and then the pressing force value is uploaded and bound to the microphone assembly information in the background.

[0047] See attached Figure 6 and 7 After the microphone is pressed together, the positioning seat 1 moves to the dustproof net pasting station.

[0048] The above-mentioned dustproof net sticking device 300 includes a dustproof net sticking component, a clamping cylinder 301 for clamping the microphone A, a rotating cylinder 302 driving the clamping cylinder 301 to rotate 180°, and a Z-axis driving cylinder 303 and a Y-axis driving slide 304 driving the rotating cylinder 302 to move to the dustproof net sticking position.

[0049] The dustproof net pasting assembly includes a dustproof net adsorption head 305, a pasting lifting cylinder 306 for driving the dustproof net adsorption head 305 to rise and fall, and an X-axis driving slide 307 for driving the pasting lifting cylinder 306 to reciprocate between the adsorption position and the pasting position.

[0050] After the dust screen is pasted, the positioning seat 1 moves to the label pasting station. Under the action of the label pasting device 400, the label is pasted to the microphone. The label pasting device 400 is an existing conventional device.

[0051] See attached Figure 3-7 and 9, the EVA pad pasting device 100, the dustproof net pasting device 300 and the label pasting device 400 are all equipped with a feeding device. The feeding device includes a film supply component 3, a film collection component 4, a film belt moving platform 5, a stripping plate 6 located at the end of the film belt moving platform 5, and a receiving plate 7 located on the other side of the stripping plate 6. The above-mentioned EVA pads, dustproof nets or labels are arranged in an array on the film belt, and the film belt is wound in the material tray of the film supply component 3. The film collection component 4 includes a film collection roller and a motor that drives the film collection roller to rotate, and the film belt is moved and stripped under the drive of the motor. When the film belt passes through the stripping plate 6, the material will be separated from the film belt and enter the receiving plate 7 for adsorption by the supporting device.

[0052] A redirecting roller 8 is provided between the film supply assembly 3 and the film strip moving platform 5, so that the film strip can move horizontally along the film strip moving platform 5 after passing through the redirecting roller 8. Pressing plates 9 are provided on both sides of the film strip moving platform 5 to guide the two sides of the film strip, and the pressing plates 9 are connected to the film strip moving platform 5 by hinges.

[0053] A camera is also provided on the corresponding device to collect the quantity, status and position of the materials on the receiving plate 7 . If the quantity is less than a predetermined quantity, the film collecting assembly 4 will be controlled to move to increase the quantity of materials on the receiving plate 7 .

[0054] See attached Figure 1 After the label is pasted, the positioning seat 1 is moved to the microphone detection station, and the microphone detection device 500 detects the performance of the microphone. The microphone detection device 500 is provided with components such as an adsorption head and a cylinder for adsorbing the microphone in the positioning seat 1 and placing it in the device housing or on the positioning seat 1. The microphone detection component in the device housing is a conventional device, such as the patents previously applied for by the applicant with the authorization announcement numbers CN114885268B and CN210274532U.

[0055] After testing the microphone performance, the positioning seat 1 moves to the microphone pin testing station. The camera in the pin testing device 700 takes a picture of the pin position of the positioning microphone, and the background will test the pin based on the image. The pin testing device 700 is an existing conventional device.

[0056] See attached Figure 8 After the microphone is tested for pin insertion, the positioning seat 1 moves to the grabbing station. The microphones are classified into different grades after the test, and then placed in a box 2 for collecting microphones of different grades under the grabbing of the sorting device 600.

[0057] The above-mentioned sorting device 600 includes a sorting adsorption head 601 for adsorbing a microphone, a sorting lifting cylinder 602 for driving the sorting adsorption head 601 to rise and fall, and a moving slide 603 for driving the sorting lifting cylinder 602 to reciprocate between a grasping position and a releasing position.
