Description

Technical Field

[0001] The invention relates to the technical field of microphone detection, in particular to a detection device that is convenient for loading materials. Background Art

[0002] Before leaving the factory, the quality of the solder joints on the PCB board must be determined to ensure that the size of the microphone meets the application requirements and that there are no defects that affect the performance. Therefore, detection is an indispensable part of the manufacturing process of the microphone. Manual detection is the most traditional detection method, but due to the small size of the microphone and the large number of them, the effect of manual detection is neither obvious nor stable, and it requires a lot of energy. Therefore, CCD detection equipment that can automatically detect is needed.

[0003] According to a publicly disclosed airflow sensor switch microphone CCD detection device (Announcement No.: CN117139182A), in the above application, a vibrating material dividing plate with a trumpet-shaped dividing groove is provided to realize the orderly transmission of the microphones to be detected, and a conveying device is cooperated, and a plurality of material placing strips with material placing grooves are evenly spaced on the conveying device to convey the microphones to be detected to the bottom of the CCD detection device, so as to realize the detection and judgment of the microphones, and feed the results back to the controller, and the controller generates a control instruction and transmits it to the material transfer mechanism to remove unqualified microphones or microphones on the non-detection surface.

[0004] However, in actual use of the above equipment, when the microphone to be tested is transported from the storage device to the bottom of the detection device, since the CCD detection device uses image comparison to perform qualified detection, the microphone needs to be manually aligned during the detection process to reduce the judgment error of the CCD detection device and improve the detection accuracy of the device.

[0025] In addition, please refer to the instructions attached Figure 2 , Figure 5-Figure 8 In this embodiment, there are two sets of vertical plates 31, and the two sets of vertical plates 31 are mirror-imaged on the left and right sides of the vertical central axis of the unloading rack 22. There are two sets of sleeves 33, and a gap of a size that matches the thickness of the contact plate 316 is provided between the two sets of sleeves 33. The transmission column 39 is provided in the internal cavity of the sleeve 33 so that the sleeve 33 and the transmission column 39 can rotate relative to each other. Furthermore, the two ends of the volute spring 35 are fixedly connected to the side wall of the connecting plate 34 and the side wall of the contact plate 316, respectively. There are two sets of return components 3, and the two sets The correction component 3 is mirror-imaged on the left and right sides of the vertical center axis of the unloading rack 22, so that when the microphone head is transported along the unloading rack 22 and is transported downward along the conveyor belt 210, the microphone head will first contact the curved plate 37. Even if the microphone head is deflected or tilted during unloading, after the microphone head contacts the curved plate 37 and the guide plate 36, it will deflect to a certain extent with the sleeve 33 due to its own posture. At this time, the connecting plate 34 is driven to tighten the volute spring 35, and then the guide plate 36 will have a reset tendency in the process of the microphone head continuing to unload, so as to prompt the microphone head to correct.

[0026] At the same time, there are several groups of limit blocks 311, and several groups of limit blocks 311 are evenly distributed on the arc-shaped inner surface of the sleeve disc 38 in a circular array, and the disc 310 is in contact with the bottom inner surface of the sleeve disc 38, and the shift block 313 and the limit block 311 are arranged in the same plane.

When the guide plate 36 is deflected, due to the restriction of the shift block 313 and the limit block 311, the rotation tendency of the transmission column 39 in the sleeve 33 is suppressed, so that the deflection process of the guide plate 36 is smoother, and the transportation safety of the microphone head is affected by the excessive rotation speed.

[0027] In the embodiments of the present invention, please refer to the attached specification Figure 3-Figure 4 A lifting assembly 4 is provided on one side of the guide plate 36 close to the central axis of the unloading rack 22. The lifting assembly 4 includes a cylindrical groove 41. A contact shaft 42 is rotatably mounted on the inner wall of the cylindrical groove 41. A spiral belt 43 is provided on the arc-shaped outer wall of the contact shaft 42. A notch groove 44 is opened on the arc-shaped outer wall of the spiral belt 43.

[0028] Specifically, the number of lifting components 4 is set to be multiple groups, and the multiple groups of lifting components 4 are evenly distributed on the side wall of the guide plate 36 in a linear array, and the diameter of the cylindrical groove 41 is larger than the outer diameter of the contact shaft 42, so that the contact shaft 42 can rotate freely in the cylindrical groove 41. Furthermore, the spiral belt 43 is set to be arc-shaped on the side of the outer surface away from the contact shaft 42 to reduce the impact force generated when the contact shaft 42 contacts the microphone on the conveyor belt 210, and the number of notch grooves 44 is set to be several groups, and several groups of notch grooves 44 are equidistantly distributed on the outer surface of the spiral belt 43. When the microphone is transported downward on the conveyor belt 210, the spiral belt 43 drives the microphone to drive the contact shaft 42 to rotate, so that there is a tendency to move upward, so that when the guide plate 36 corrects the microphone, no large friction will occur between the microphone and the conveyor belt 210, thereby avoiding damage to the microphone during the detection and transportation process, affecting the production quality of the product.

[0029] For further information, please refer to the attached manual. Figure 5-Figure 6A feedback assembly 5 is provided on the side of the vertical plate 31, which can cause the guide plate 36 to return to the normal position as the conveyor belt 210 moves. The feedback assembly 5 includes a contact wheel 51, which is rotatably mounted on the side wall of the vertical plate 31, and a large bevel gear 52 is coaxially fixedly mounted on the contact wheel 51. A round rod 53 is rotatably mounted on the side wall of the vertical plate 31, and a small bevel gear 54 is fixedly mounted on the bottom end of the round rod 53. A transmission wheel 1 55 is fixedly mounted on the top end of the round rod 53, and the transmission wheel 1 55 is connected to a transmission wheel 2 57 through a transmission belt 56.

[0030] It is worth noting that the bottom of the contact wheel 51 is in contact with the upper surface of the conveyor belt 210, so that when the conveyor belt 210 is transported, the contact wheel 51 is driven to rotate. At the same time, the small bevel gear 54 is meshed with the large bevel gear 52 to realize transmission, so that when the contact wheel 51 rotates, it cooperates with the large bevel gear 52 and the small bevel gear 54, so that the round rod 53 drives the transmission wheel 1 55 to rotate. Specifically, the axis of the transmission wheel 2 57 is fixedly connected to the transmission column 39, and the diameter of the large bevel gear 52 is set to twice the diameter of the small bevel gear 54, so that the transmission wheel 2 57 drives the transmission column 39 to rotate, and then in the process of deflection when the guide plate 36 is corrected for drainage, the contact plate 316 is driven to deflect through the active rotation of the transmission column 39, and then the volute spring 35 drives the connecting plate 34 and the guide plate 36 to reset, so that the microphone head is quickly corrected to facilitate the CCD detection equipment to identify and detect it.

[0031] In the present invention, when in use, the microphone to be detected is transported upward by the circular vibration loading plate 21, and then dropped onto the unloading rack 22, and at the same time, the driving motor 29 is started, and the transmission roller on its output shaft is cooperated to make the conveyor belt 210 continue to be transported downward, and the microphone will first contact the arc plate 37. Even if the microphone deflects or tilts during unloading, the microphone will deflect to a certain extent with the sleeve 33 due to its own posture after contacting the arc plate 37 and the guide plate 36. At this time, the spiral spring 35 is tightened by the connection plate 34, and then the guide plate 36 will have a reset tendency during the process of the microphone continuing to unload, so as to prompt the microphone to return to the right position, and finally enter the conveying rack along with the transportation of the conveyor belt 210. On the material rack 25, as the conveying device in the feeding rack 25 transports it, it passes directly under the CCD detection device 23. The qualified products after the inspection will not be affected. They are transported outward through the qualified material unloading plate 26 along with the transmission of the feeding rack 25. If the microphone after the inspection is a defective product, the robot 24 will grasp the defective product and rotate it 90°, so that the robot 24 pushes the defective product to the defective product unloading plate 27. If the CCD detection device 23 detects and identifies the microphone as a flipped unidentified product, the robot 24 will grasp the microphone and rotate it 180° to transport the microphone to the reflux unloading port 28 and collect it for subsequent re-inspection, thereby realizing the diversion and collection of microphones with different identification results.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
