Description

Technical Field

[0001] This utility model relates to the field of flipping device technology, and in particular to a voice coil flipping device. Background Technology

[0002] In the consumer electronics industry, some product processes involve bonding voice coils and centering supports: after the centering support is glued, the voice coil insert, along with the voice coil, flips and snaps onto the centering support. Then, the voice coil insert flips a second time and separates from the voice coil. The voice coil and centering support are bonded in subsequent processing steps and finally cured under UV pressure. However, due to differences in the fit clearance between the voice coil and the voice coil insert, glue residue, and deformation, the second flipping process can easily result in the voice coil insert carrying the voice coil, ultimately leading to poor yield in this unloading process. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technology and provide a voice coil flipping device that ensures continuous pressure holding function when the voice coil insert is disengaged, and completely avoids the phenomenon of the voice coil insert carrying the voice coil.

[0004] The purpose of this utility model is achieved through the following technical measures: a voice coil flipping device, including a flipping component, the flipping component including a flipping bracket, the center of the flipping bracket having a first through hole, a plurality of flipping units being evenly spaced in the first through hole, the flipping component being connected to a first driving device, and the first driving device being connected to a second driving device.

[0005] As a further improvement to the above technical solution: The flipping unit includes a clamping cylinder, with cylinder connecting arms on both sides of the upper end of the clamping cylinder. Each of the two cylinder connecting arms is connected to a gripper, and the two grippers are symmetrically arranged. A pressure head fixing frame is provided between the lower parts of the two grippers. A pressure head spring is provided inside the pressure head fixing frame. The upper end of the pressure head spring extends out of the pressure head fixing frame and is fixedly connected to a pressure block. A voice coil pressure-holding pressure head is provided at the upper center of the pressure block.

[0006] A fixing plate is fixedly connected to one side of the clamping cylinder, and the pressure head fixing bracket is fixedly mounted on the fixing plate. Both ends of the fixing plate are fixed to the flipping bracket.

[0007] A voice coil insert is placed above the pressure block, and two voice coil positioning blocks are provided on the voice coil insert. A second through hole is provided on the voice coil insert between the two voice coil positioning blocks.

[0008] Two voice coil positioning blocks are symmetrically arranged, and the height of the voice coil positioning blocks above the upper surface of the voice coil insert is 0.9-1.1mm.

[0009] The width of the second through hole is greater than the width of the voice coil pressure head, and the two voice coil positioning blocks are respectively provided with a third through hole on the side away from the second through hole.

[0010] The two ends of the flipping bracket are respectively connected to rotating shafts. One end of the rotating shaft is connected to a driven wheel via a spline, and the other end of the rotating shaft is connected to a stop. Bearings are respectively provided between the driven wheel and the flipping bracket, and between the stop and the flipping bracket.

[0011] The first driving device includes a motor, which is located behind one side of the tilting bracket. The motor is fixedly connected to a first rib, one end of which is fixedly connected to a bearing between the driven wheel and the tilting bracket. The first rib has a through hole that can accommodate the bearing. The motor is driven by a driving wheel that passes through the first rib. The first rib has a through hole that can accommodate the driving wheel. A drive belt is driven between the driving wheel and the driven wheel.

[0012] The other side of the flipping bracket is provided with a second rib plate. One end of the second rib plate is fixedly connected to the bearing between the stop and the flipping bracket. The second rib plate is provided with a through hole that can accommodate the bearing.

[0013] The second driving device includes an electric cylinder, which has an electric cylinder connector. The electric cylinder connector is connected to a connecting plate. A base plate is fixedly connected to the lower end of the connecting plate. The two ends of the base plate are fixedly connected to a first rib and a second rib, respectively.

[0014] Compared with the prior art, the advantages of this utility model are as follows: Addressing the problem of low unloading yield of voice coil inserts, it fundamentally improves the phenomenon of voice coil inserts carrying the voice coil during the flipping process due to excessive tightness between the voice coil and the voice coil insert. By setting a voice coil pressure-holding head at the center of the voice coil insert, a voice coil pressure-holding function is achieved at the moment of separation of the voice coil insert, ensuring that the voice coil insert flips independently, completely avoiding the phenomenon of voice coil inserts carrying the voice coil, and improving the flipping yield to approximately 99.8%.
