DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0028] Example 1: A vehicle-mounted microphone assembly processing device, such as Figures 1-4As shown, it includes a chassis 1, the top of the chassis 1 is fixedly connected to a bottom plate 11, the top rear side of the bottom plate 11 is fixedly connected to a shell 12, a punch 13 is installed on the upper front side of the shell 12, the top front side of the bottom plate 11 is fixedly connected to a mold 115, the mold 115 is located directly below the punch 13, a channel for unloading is opened on the top rear side of the chassis 1, four tracks 16 symmetrically distributed along the mold 115 are fixedly connected to the bottom plate 11, a lifting motor 17 is installed on the left front side of the bottom plate 11, the output shaft on the upper side of the lifting motor 17 is connected to a lifting screw 18 through a coupling, and a connecting piece 19 is threadedly connected to the lifting screw 18. The right front side of the bottom plate 11 is fixedly connected to the guide rod 11 6. A sliding block 117 is slidably connected to the guide rod 116. A connecting rod 110 is fixed in the connecting piece 19 and the sliding block 117. A clamp 112 symmetrically distributed front and back is slidably connected between the two connecting rods 110. A linear spring 113 is connected between the two clamps 112 and the two connecting rods 110. The four linear springs 113 are all wound around the adjacent connecting rods 110. An extrusion frame 111 is fixed to the bottom of the connecting piece 19. A mesh cover 114 is clamped between the two clamps 112. A unloading assembly for receiving the mesh cover 114 is provided on the outer shell 12. A curved slide groove is opened in the four tracks 16, and the clamps 112 slide in the adjacent curved slide grooves.

[0029] like Figure 4 As shown, the unloading assembly includes a sleeve rod 15, and the sleeve rods 15 are fixed to the lower part of the outer shell 12 and are symmetrically distributed on the left and right. A unloading rack 118 is slidably connected between the two sleeve rods 15, and symmetrically distributed return springs 14 are connected between the rear side of the unloading rack 118 and the outer shell 12. The two return springs 14 are both wound around the adjacent sleeve rods 15, and the extrusion rack 111 is extruded and fitted with the unloading rack 118.

[0030] like Figure 5-Figure 7 As shown, it also includes a cleaning mechanism for removing the cut scraps from the mold 115. The cleaning mechanism is arranged on the sliding block 117. The cleaning mechanism includes a lifting rod 21, which is fixedly connected to the bottom of the sliding block 117. An elliptical through hole is opened on the bottom plate 11. The lifting rod 21 is slidably connected to the supporting plate 2. A circular through hole is opened in the supporting plate 2. The supporting plate 2 is sleeved on the mold 115. The right side of the supporting plate 2 is rotatably connected to the limiting rod 22, and the left side of the supporting plate 2 is rotatably connected to the pushing screw 24. The pushing screw 24 is threadedly connected with a cleaning plate 23. The cleaning plate 23 is slidably connected to the limiting rod 22. The cleaning plate 23 contacts the top of the supporting plate 2. The left rear side of the supporting plate 2 is fixedly connected to a fixed block 26. A servo motor 25 is installed on the fixed block 26. The output shaft of the servo motor 25 on the front side is connected to the pushing screw 24 through a coupling.

[0031] Initially, the connecting rod 110 is in the lower position inside the track 16, so that the connecting part 19, the sliding block 117, the extrusion frame 111, and the clamp 112 stay at the bottom, and the clamp 112 is in an outward separated state. The extrusion frame 111 presses the unloading frame 118, and the bottom of the support plate 2 contacts the top of the base plate 11. The linear spring 113 and the reset spring 14 are both in a deformed state. When it is necessary to make the mesh cover 114, two collection boxes are placed on the front and back sides of the device in advance. Secondly, the metal mesh for making the microphone mesh cover 114 is placed in the center of the mold 115, and the punching machine 13 is controlled to move downward to punch the metal mesh on the mold 115. After the stamping is completed, the punching machine 13 is controlled to move upward and reset. The stamped mesh cover 114 will be put on the mold 115, and the scraps produced by the stamping will be caught by the support plate 2.

[0032] At this time, the lifting motor 17 can be controlled to drive the lifting screw 18 to rotate forward, thereby driving the connecting member 19 to drive the connecting rod 110, the sliding block 117, the extrusion frame 111, the clamp 112, the lifting rod 21, the supporting plate 2, etc. to move upward together. Since there is a bent slide groove in the track 16, as the clamp 112 moves upward along the bent slide groove, and under the elastic force of the linear spring 113, the clamp 112 will gradually move inward and clamp the mesh cover 114, and the clamp 112 will drive the mesh cover 114 to move upward together. When the pressing frame 111 moves upward to the inner upper side of the track 16, the two clamps 112 will separate outwards to release the mesh cover 114. At the same time, when the upwardly moving extrusion frame 111 no longer presses against the discharge frame 118, the discharge frame 118 will move forward to be located directly below the mesh cover 114 under the elastic force of the return spring 14. The released mesh cover 114 will fall onto the discharge frame 118 under its own gravity, and slide downward along the discharge frame 118 to the unloading channel of the chassis 1, and then continue to roll backward through the unloading channel to the collection box at the rear side.

[0033] At the same time, the upward moving support plate 2 will be slightly higher than the mold 115, and the servo motor 25 can be controlled to drive the push screw 24 to rotate forward first and then reverse, thereby driving the cleaning plate 23 to move forward to push the material and then move backward to reset. The forward moving cleaning plate 23 will push the scraps on the support plate 2 into the collection box on the front side for easy recycling.

[0034] Then the lifting motor 17 is controlled to drive the lifting screw 18 to reverse, and the connecting part 19 will drive the connecting rod 110, the sliding block 117, the extrusion frame 111, the clamp 112, the lifting rod 21, the supporting plate 2, etc. to move downward and reset. The extrusion frame 111 is again against the unloading frame 118, so that the unloading frame 118 moves back to the initial position, and the above operation is repeated to continue punching the metal mesh placed on the mold 115.

[0035] To sum up, the track 16, connecting rod 110, clamp 112, extrusion frame 111, unloading frame 118 and the like cooperate with each other to remove the stamped mesh cover 114 from the mold 115 and unload it into the collection box on the rear side, and then the scraps produced by stamping are cleaned by the support plate 2 and the cleaning plate 23, realizing the full automation operation from stamping to taking out and then cleaning up the scraps, which not only reduces manual intervention and labor intensity, but also improves production efficiency and product quality.

[0036] Example 2: Based on Example 1, Figures 8-10 As shown, it also includes a stabilizing mechanism for clamping and positioning the metal mesh placed on the mold 115. The stabilizing mechanism is arranged on the shell 12. The stabilizing mechanism includes a limit frame 3. The limit frames 3 symmetrically distributed on the left and right are all fixed to the shell 12. The tops of the connecting members 19 and the sliding blocks 117 are fixed with support plates 31. The two support plates 31 are slidably connected with clamping members 32. Two buffer springs 33 are connected between the clamping members 32 and the adjacent support plates 31. Each buffer spring 33 is wound around the adjacent clamping member 32. The buffer spring 33 is always in a slightly deformed state. Each support plate 31 is provided with a gear assembly on the side close to the base plate 11.

[0037] like Figure 10 As shown, the shift assembly includes a shift block 35, and the shift blocks 35 symmetrically distributed front and back are all slidably connected to the lower part of each limit frame 3, and a return spring 34 is connected between the shift block 35 and the adjacent limit frame 3, and each return spring 34 is wound around the adjacent shift block 35; the lower part of the limit frame 3 is provided with an inclined surface, and the limit frame 3 and the adjacent clamping member 32 are squeezed together, and the clamping member 32 and the adjacent shift block 35 are also squeezed together.

[0038] As mentioned above, when the clamp 112 moves upward, the clamp 112 will drive the support plate 31 and the clamping member 32 to move upward together, and the inclined surface at the bottom of the limit frame 3 will press against the clamping member 32, so that the clamping member 32 moves upward and slides outward, and the buffer spring 33 is in a compressed state. When the upward clamping member 32 contacts the stop block 35, the clamping member 32 will squeeze the stop block 35 to make it slide outward, and the return spring 34 will be compressed. When the clamping member 32 passes the stop block 35, under the elastic force of the return spring 34, the stop block 35 slides inward and resets, while the clamping member 32 maintains an upward trajectory along the contour of the limit frame 3.

[0039] When the clamp 112 moves downward and is in a closed state, the staff can place the metal mesh in the center of the closed clamp 112, and the metal mesh moves downward synchronously with the clamp 112 and the clamping member 32. When the clamp 112 moves downward and is in an open state, the metal mesh on the clamp 112 will be supported by the mold 115. At the same time, when the downward-moving clamping member 32 passes the vertical surface of the limit frame 3, under the elastic force of the buffer spring 33, the clamping member 32 will slide inward and lightly clamp the metal mesh. The two-way clamping force ensures that the metal mesh is accurately centered. The metal mesh that has been centered maintains a stable posture on the mold 115 platform, providing precise alignment conditions for the stamping process of the punching machine 13.
