[0032] As shown in Figure 1 and Figure 4 The material blocking positioning mechanism 11 includes an electric push rod 112 and a material blocking block 113, three electric push rods 112 are uniformly installed on the upper rear side of the bottom frame 1, the material blocking block 113 for blocking the electric rotary disc 10 is connected to the telescopic rod of the electric push rod 112, and the three electric push rods 112 are electrically connected with the controller 101.

[0033] As shown in Figure 1 , Figure 5 and Figure 6 The centering and compacting mechanism 12 includes a pressing frame 121, a positioning ring 122, a centering block 123, a compacting spring 124, a compression spring 125, a rotating ring 126 and a dryer 127, the pressing frame 121 is slidably provided on the left connecting frame 7, the compression spring 125 is connected between the pressing frame 121 and the left connecting frame 7, the positioning ring 122 is slidably provided on the lower part of the pressing frame 121, the compacting spring 124 is uniformly connected between the positioning ring 122 and the pressing frame 121, the centering block 123 is uniformly connected to the inner side of the positioning ring 122, the rotating ring 126 is rotatably provided on the bottom of the pressing frame 121, the rotating frame 8 can extrude the pressing frame 121 to move downward, so that the rotating ring 126 moves downward to compact the diaphragm 92 and the voice coil 93, the dryer 127 for drying glue is installed on the rear side of the positioning ring 122, and the dryer 127 is electrically connected with the controller 101.

[0034] When the voice film 92 needs to be processed, the glue is first added into the two storage barrels 6, then an electric rotating disc 10 is placed on the flat belt 4, the electric rotating disc 10 is aligned with the glue head 9 on the right side, the bottom disc 91 is clamped on the electric rotating disc 10, and the voice film 92 is clamped on the bottom disc 91. The controller 101 is controlled to drive the rotating motor 21 on the right side to rotate, so that the output shaft of the rotating motor 21 rotates to drive the rotating frame 8 to rotate downward, so that the corresponding glue head 9 moves downward and contacts the outer side of the voice film 92. At this time, the controller 101 is controlled to drive the electric rotating disc 10 to rotate, so that the rotating part on the electric rotating disc 10 rotates with the bottom disc 91 and the voice film 92. The glue head 9 is opened, so that the glue in the storage barrel 6 flows into the glue head 9. The glue head 9 coats the glue on the voice film 92. The voice film 92 rotates to make the glue coat along the circle. After the glue is applied, the electric rotating disc 10 is closed, the voice coil 93 is adhered to the position where the glue is applied on the voice film 92, the glue head 9 is closed through the controller 101, and the rotating motor 21 is controlled to reverse rotation to reset. The glue head 9 is lifted to reset. The drive motor 2 is turned on, so that the drive motor 2 drives the pulley 3 and the flat belt 4 to rotate. The flat belt 4 drives the electric rotating disc 10 to move to the left side. Because the material blocking block 113 blocks the electric rotating disc 10, the operator can control the two electric push rods 112 on the right side to extend through the controller 101, so that the material blocking block 113 moves backward and no longer blocks the electric rotating disc 10. The electric rotating disc 10 moves to the left side due to the transmission of the flat belt 4. After completion, the two material blocking blocks 113 on the right side are reset. When the electric rotating disc 10 moves to the left side and contacts the material blocking block 113 on the left side, the material blocking block 113 blocks the electric rotating disc 10, which represents that the electric rotating disc 10 moves to the appropriate position.

[0035] At this time, the operator controls the rotating motor 21 on the left side to rotate, so that the rotating frame 8 rotates to drive the glue head 9 to move downward. The rotating frame 8 rotates to press the downward pressing frame 121 to move downward, so that the compression spring 125 is compressed. The downward pressing frame 121 drives the positioning ring 122 and the centering block 123 to move downward. The dryer 127 and the rotating ring 126 also move downward. When the positioning ring 122 moves downward to contact the bottom frame 1, the downward movement is stopped. The centering block 123 also contacts the voice film 92 to center and limit the voice film 92. The downward pressing frame 121 continues to move downward to compress and compact the spring 124. The rotating ring 126 presses the voice coil 93, so that the voice coil 93 and the voice film 92 are compacted. The glue head 9 on the left side contacts the connection between the voice coil 93 and the voice film 92. At this time, the controller 101 is controlled to drive the electric rotating disc 10 to rotate with the voice film 92 and the voice coil 93, and the glue head 9 on the left side is opened, so that the glue is coated on the connection between the voice film 92 and the voice coil 93 for secondary gluing. At the same time, the dryer 127 is opened to dry the glue, so as to ensure the stability of the connection between the voice film 92 and the voice coil 93.

[0036] After the sound film 92 and the voice coil 93 are glued and compacted, the electric rotating disc 10 is closed, the left rotating motor 21 is controlled to operate reversely, the dispensing head 9 and the rotating frame 8 are reset, the left rotating frame 8 is reset reversely and no longer presses the lower pressing frame 121, the lower pressing frame 121 moves upwards with the positioning ring 122 and the rotating ring 126 under the reset action of the compression spring 125, the compacting spring 124 also rebounds and resets, thus the gluing of the sound film 92 and the voice coil 93 is completed, then the left electric push rod 112 is controlled by the controller 101, the left blocking block 113 moves to the rear side and no longer blocks the electric rotating disc 10, the electric rotating disc 10 continues to be pushed to the left side, which facilitates the operator to take out the electric rotating disc 10, and the above operation is performed, the electric rotating disc 10 can be placed on the flat belt 4 in sequence, and the bottom disc 91 and the sound film 92 are clamped on the electric rotating disc 10, so as to perform the gluing processing of the sound film 92 and the voice coil 93, the sound film 92 and the voice coil 93 are adhered more firmly through the first dispensing of the right dispensing head 9 and the second dispensing of the left dispensing head 9, the driving motor 2 continues to operate to make the flat belt 4 push the electric rotating disc 10, and the blocking and positioning mechanism 11 blocks the electric rotating disc 10, without repeatedly opening and closing the driving motor 2, only when the electric rotating disc 10 needs to be moved, the blocking block 113 is pushed to the rear side by operating the controller 101, which reduces the labor cost, guarantees the processing quality, and improves the overall work efficiency.

[0038] When the rotating frame 8 rotates downward with the glue head 9 to glue the diaphragm 92 and the voice coil 93, the rotating frame 8 will push the push rod 131 to move upward, so that the reset spring 137 is stretched, the upward movement of the push rod 131 drives the articulated rod 133 to rotate, the articulated rod 133 pushes the rack 134 to move to the left side, and then drives the gear with missing teeth 136 and the limiting block 135 to rotate, so that the limiting block 135 contacts the electric turntable 10, and then cooperates with the blocking block 113 to limit the electric turntable 10, so as to avoid the left and right deviation of the electric turntable 10. After the gluing is completed, the rotating frame 8 reverses to move upward with the glue head 9, and the rotating frame 8 no longer presses the push rod 131, so that the push rod 131 moves downward under the reset action of the reset spring 137, and then drives the articulated rod 133 to reverse and reset, so that the articulated rod 133 pushes the rack 134 to move to the right side, and then drives the gear with missing teeth 136 and the limiting block 135 to reverse and reset.

[0039] As shown in Figure 1 and Figure 9 , it also comprises a vibrating unloading mechanism 14, the vibrating unloading mechanism 14 comprises a fixed frame 141, a vibrating motor 142, and a vibrating frame 143, the middle of the top rear side of the bottom frame 1 is fixedly provided with the fixed frame 141, the vibrating motor 142 is symmetrically installed on the fixed frame 141, the vibrating motor 142 is electrically connected with the controller 101, and the vibrating frame 143 is slidably arranged on the fixed frame 141.

[0040] When the diaphragm 92 is processed, the vibrating motor 142 is turned on by operating the controller 101, the vibrating motor 142 vibrates, and then the vibrating frame 143 vibrates. After the glue on the right side of the glue head 9 is applied to the diaphragm 92, the controller 101 is controlled to move the blocking block 113 on the right side backward to no longer block the electric turntable 10, so that the electric turntable 10 moves to the left side with the diaphragm 92. After the electric turntable 10 is blocked by the blocking block 113 in the middle, the operator can place the voice coil 93 along the inner side of the vibrating frame 143, so that the voice coil 93 moves downward due to the vibration of the vibrating frame 143, and then accurately sticks to the diaphragm 92. The vibrating frame 143 can avoid the voice coil 93 from being stuck during unloading. After the sticking is completed, the blocking block 113 in the middle is moved backward, so that the electric turntable 10 moves to the left side with the voice coil 93 and the diaphragm 92, and the voice coil 93 is glued again. By using the vibrating unloading mechanism 14 to replace manual sticking of the voice coil 93, the accuracy of sticking the voice coil 93 can be improved, and the diaphragm 92 processing work can be orderly carried out.
