Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing technology, and in particular to a loudspeaker drum paper auxiliary fixing device. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. During loudspeaker manufacturing, the diaphragm needs to be glued to the inside of the bracket. The common installation method is to use adhesive to fix it in place. During this process, adhesive is applied to the edges of the diaphragm before it is attached to the inside of the bracket. This process is prone to slippage, causing adhesive to overflow into other areas. Furthermore, insufficient pressure after installation can cause some areas to detach from the adhesive. Therefore, a diaphragm auxiliary fixing device is needed to position and pre-install the diaphragm, and effective pressure should be applied to the glued area after installation to prevent cracks.

Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0013] like Figure 1-4 The speaker drum diaphragm auxiliary fixing device shown includes a base 1, a cylinder frame 2, a cylinder 3, a lifting frame 4, an insertion tube 5, a control mechanism 6, a pressure rod 7, a pressure applying mechanism 8, and a support base 9. The cylinder frame 2 and the support base 9 are fixedly mounted on the upper surface of the base 1. The cylinder 3 is fixed to the inner top of the cylinder frame 2. The lifting frame 4 is fixedly mounted on the telescopic end of the cylinder 3. The insertion tube 5 is fixedly mounted on one top end of the lifting frame 4. The control mechanism 6 is inserted into the insertion tube 5. The pressure rod 7 is fixedly mounted at the bottom of one end of the control mechanism 6. The pressure applying mechanism 8 is fixedly mounted at the bottom of the pressure rod 7. The control mechanism 6 includes an adjusting block 61, a folding rod 62, and a retaining shaft 63. The folding rod 62 is movably connected to one end of the adjusting block 61 via the retaining shaft 63. The pressure applying mechanism 8 includes a pressure applying frame 81, a guide rod 82, an adhesive rubber 83, a retaining ring 84, a rotating shaft 85, and a pressure applying seat 86. The guide rod 82 is movably connected to the top of the pressure applying frame 81. The adhesive rubber 83 is fixedly installed at the bottom of the guide rod 82. The retaining ring 84 is fixedly installed at the top of the guide rod 82. The rotating shaft 85 is movably connected to the top of the pressure applying frame 81. The pressure applying seat 86 is fixedly installed at the top of the rotating shaft 85.

[0014] Specifically, a guide groove is provided on the outer side of the cylinder frame 2, a guide strip is provided at the bottom of the lifting frame 4, the bottom guide strip of the lifting frame 4 is locked in the guide groove on the outer side of the cylinder frame 2, limit blocks are provided on both sides of the adjusting block 61, a limit groove is provided on the inner side of the insertion tube 5 to cooperate with it, the cross section of the folding rod 62 is matched with the inner hole of the insertion tube 5, the bottom of the pressure seat 86 is locked on the top of the retaining ring 84, a support plate is provided at the bottom of one end of the adjusting block 61, and the bottom of one end of the folding rod 62 is in contact with the upper surface of the support plate at one end of the adjusting block 61.

[0015] In this embodiment, firstly, the pressure seat 86 is rotated to rotate the shaft 85 until the pressure seat 86 is engaged with the top of the retaining ring 84, thus fixing the adhesive rubber 83. Then, the pressure rod 7 is held and pulled outward, thereby pulling the adjusting block 61 out of the insertion tube 5. The limiting blocks on both sides of the adjusting block 61 move to the end of the limiting groove inside the insertion tube 5. At this time, the connection between the folding rod 62 and the adjusting block 61 is exposed. Then, the folding rod 62 is flipped upward, so that it rotates upward around the retaining shaft 63. At this time, the drum paper is moved and pasted onto the surface of the adhesive rubber 83. The surface of the adhesive rubber 83 has a certain adhesive force, which facilitates the fixing of the drum paper. When the surface adhesion decreases, it can be wiped with a damp cloth. After the drum paper is initially fixed, the folding rod 62 is rotated downward until the bottom of one end of it contacts the support plate at the bottom of one end of the adjusting block 61, so that the folding rod 62 is in a horizontal state. Then, the pressure rod 7 is pushed inward until the adjusting block 61 moves to the bottom of the insertion tube 5.

[0016] Furthermore, the bracket is placed in the top slot of the support base 9, and the hydraulic cylinder 3 is controlled to retract, causing the lifting frame 4 to descend. The guide bar at the bottom of the lifting frame 4 moves down in the guide groove on the outside of the hydraulic cylinder frame 2. The guide bar supports the insertion tube 5 and guides its descent. After the adjusting block 61 moves into the insertion tube 5, the connection position will be locked in the insertion tube 5. Thus, the downward pressure of the hydraulic cylinder 3 can be transmitted downward through the folding rod 62. When the hydraulic cylinder 3 descends to the installation position of the pressure frame 81 with the drum paper installed inside the bracket, the pressure seat 86 is rotated to make it misaligned with the retaining ring 84. At this time, under the pressure, the guide rod 82 rises, and the adhesive rubber 83 separates from the drum paper, ensuring the pressure effect. Under the uniform pressure of the annular pressure frame 81, the pasting effect is ensured, and misalignment is effectively avoided.
