The moving distance of L-type push plate 32 is greater than the width of box body 31, and when withdrawing at every turn, another microphone positioning mold 2 can fall normally, get ready for next normal pushing microphone positioning mold 2.
[0033] see Image 6 and Figure 7 The vibrating plate feeding mechanism 4 includes: a lateral movement section 41 and a longitudinal output end 42, and a gradually narrowing microphone guide plate 411 is provided above the horizontal movement section 41, which can correct the insertion on the microphone during the vibration feeding process. The needle is oriented, and the longitudinal output end 42 is provided with a single output push plate 421 and a mold baffle plate 422. The single output push plate 421 is arranged in a misalignment with the conveying groove of the lateral movement section 41, and only one microphone can pass through at a time. The single output push plate 421 The length is slightly longer than the delivery groove length of the longitudinal output end 42, so that when a single output of the microphone is guaranteed, other microphones will not enter the longitudinal output end 42. The conveyor belt transports the microphone positioning mold 2 to the corresponding position of the longitudinal output end 42 according to the set distance, aligns the microphone station 21, pushes the microphone with a single output push plate 421, and fixes the microphone through the clamping position 23 In the microphone station 21, during the pushing process, the mold baffle plate 422 supports the microphone positioning mold 2 to prevent the microphone positioning mold 2 from being pushed away.
[0034] see Figure 8 , PCB board positioning die output mechanism 5 comprises: two lifting synchronous belts 51, guide rod 52, the lifting synchronous belt 51 is provided with the second dividing plate 511, and PCB board positioning mold 6 is placed on the relative second dividing plate 511, it is positioned by the guide rod 52, and the lifting synchronous belt 51 rotates at a fixed distance according to the set instruction, and the PCB board positioning mold 6 is placed on the microphone head positioning mold 2 on the conveyor belt 1, and the microphone head and PCB board for plug-in. The bottom of the guide rod 52 is flush with the positioning protrusion 22 on the microphone positioning die 2, and when the PCB board positioning die 6 does not contact the microphone positioning die 2, it is positioned by the guide rod 52. When contacting the positioning protrusion 22 on the microphone head positioning mold 2, change the positioning protrusion 22 into positioning to ensure the continuity of positioning.
[0035] see Figure 9 and Figure 10 , the PCB board positioning mold 6 is provided with a PCB board station 63 corresponding to the microphone station 21, and a positioning hole 61, a guide hole 62, the guide hole 62 cooperates with the guide rod 52, the positioning hole 61 cooperates with the positioning protrusion 22, The PCB board station 63 is provided with an annular protrusion 64 to fix the PCB board, and the PCB board station 63 has a transparent structure, leaving space for subsequent welding.
[0036] see Figure 5 and Figure 8 , preferably, a first viewing port 312 and a second viewing port 53 are respectively provided on the delivery mechanism 3 of the microphone positioning die and the output mechanism 5 of the PCB positioning die of the present invention. It is convenient for the staff to observe the real-time status of the microphone positioning die 2 and the PCB board positioning die 6 in real time, and it is convenient to find problems and solve them in time and repeatedly discharge materials.
[0037] Preferably, the conveyor belt of the present invention is a synchronous belt, and a support device is provided under the synchronous belt to ensure the stability of the belt running and more accurate control of the transmission distance.
[0038] see image 3 , further, the positioning protrusion 22 of the present invention has an elastic groove 221, the elastic groove 221 makes the middle of the positioning protrusion 22 suspended, the positioning protrusion 22 is deformed after being squeezed, and is used for positioning the microphone head positioning mold 2 and the PCB board. After the mold 6 is matched, pre-tightening force is provided to ensure the reliability of the matching.
[0039] Furthermore, the microphone head station 21 of the present invention has a reserved hole 24 for the ejector rod. After the welding is completed, the microphone head is ejected from the microphone head station 21 through the ejector rod, so as to facilitate the removal of the microphone head after the subsequent welding is completed. take out.
[0040] In summary, the present invention transports the microphone positioning mold to the conveyor belt by setting the microphone positioning mold delivery mechanism at the front end of the conveyor belt, and sets the vibrating plate feeding mechanism at the middle section of the conveyor belt to put the microphone into the microphone. On the positioning mold, set the PCB board positioning mold output mechanism at the rear position of the conveyor belt, install the positioned PCB board on the microphone positioning mold, complete the plug-in, and enter the welding process with the transmission of the conveyor belt. The whole process is completed on a transmission belt, which is simple in structure and easy to use. The microphone positioning mold is equipped with several stations, and several PCB boards can be inserted at one time, with high efficiency.
