Description

Technical Field

[0001] This invention relates to a loudspeaker assembly apparatus. Background Technology

[0002] A loudspeaker, also known as a "horn," is a commonly used electroacoustic transducer found in almost every sound-producing electronic and electrical device. It converts electrical signals into sound signals. To ensure a more robust and durable loudspeaker assembly, the loudspeaker and its mounting plate are press-fitted together and secured with screws to form a loudspeaker assembly, which is then installed into the housing. Currently, the assembly process typically involves using a press-fit device to first press the loudspeaker and mounting plate together, followed by manual tightening of screws to secure the connection. However, this method is cumbersome, and manual screw tightening is time-consuming and labor-intensive, hindering production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a loudspeaker assembly device with a reasonable structure, convenient operation, and low degree of manual intervention, which is conducive to achieving efficient product assembly.

[0004] To achieve the above objectives, the technical solution of the present invention is to design a loudspeaker assembly equipment, including a frame, a pressing device, and a screw tightening device;

[0005] The frame includes a work platform with a vertical plate and a horizontal plate connected to the top of the vertical plate;

[0006] The pressing device includes a pressing plate, a lifting plate, and a lifting drive mechanism. The top of the working platform is provided with a first positioning groove. The lifting drive mechanism is set on a horizontal plate. The lifting plate is set below the horizontal plate and is fixedly connected to the output end of the lifting drive mechanism. The pressing plate is set below the lifting plate and is connected to the lifting plate through an elastic mechanism. The bottom of the pressing plate is provided with a second positioning groove corresponding to the first positioning groove.

[0007] The screw-tightening device includes a vertical toothed plate, a first rotating rod, and a second rotating rod. The first and second rotating rods are rotatably connected to a lifting plate, and both the first and second rotating rods have magnetic screwdriver heads at their bottom ends. The pressing plate has a first through hole for the magnetic screwdriver heads to pass through, and the lifting plate has a second through hole. The vertical toothed plate passes through the second through hole, and its bottom end is fixedly connected to the pressing plate. The top of the lifting plate has a bearing seat, on which a drive shaft is rotatably connected. One end of the drive shaft has a circular gear that meshes with the vertical toothed plate, and the other end of the drive shaft has a first bevel gear. The top end of the first rotating rod has a second bevel gear that meshes with the first bevel gear. The first rotating rod has a first pulley, and the second rotating rod has a second pulley. A drive belt connects the first pulley and the second pulley. By adopting the above scheme, when the pressing plate descends to contact the working platform, the speaker and the bracket plate are pressed into the first and second positioning slots. Then, the lifting plate continues to descend, driving the first and second rotating rods downwards together. During this descent, the first and second rotating rods can rotate, screwing the screws attracted by the magnetic screwdriver head into the bracket plate and the speaker, thereby completing the fixed connection between the bracket plate and the speaker, and completing the assembly of the speaker assembly. The speaker assembly equipment of this invention is easy to operate and requires minimal manual intervention, which is beneficial for achieving efficient product assembly.

[0008] Preferably, a product output conveyor belt is provided below the working platform, and a material unloading channel communicating with the first positioning slot is provided at the bottom of the working platform. The working platform also has a push-pull channel communicating with the first positioning slot inside. A movable carrier plate is provided in the first positioning slot, with one end extending into the push-pull channel and the other end inserted into the slot wall of the first positioning slot. A support slot for inserting the movable carrier plate is provided on the slot wall of the first positioning slot. A push-pull drive cylinder is provided on the side of the working platform, with its piston rod extending into the push-pull channel and fixedly connected to the movable carrier plate. By adopting the above solution, the assembled speaker components can be conveniently transported to a designated location without manual removal and transfer of products, which is beneficial for further improving the automation level of the equipment.

[0009] Preferably, the second positioning groove has suction holes on its wall, and these suction holes are connected to an external negative pressure device via flexible hoses. This design allows the workpiece to be suctioned and fixed in the second positioning groove.

[0010] Preferably, the elastic mechanism includes four springs connected between the pressure plate and the lifting plate, and the four springs are arranged in a rectangular shape. By adopting the above solution, an elastic connection between the pressure plate and the lifting plate is achieved.

[0011] Preferably, a guide rod is inserted through the spring, the bottom end of the guide rod is fixedly connected to the pressure plate, and the top end of the guide rod passes through the lifting plate and extends above the lifting plate. The lifting plate is provided with a sliding hole for the guide rod to pass through. By adopting the above solution, the relative position between the lifting plate and the pressure plate can be prevented from shifting in the horizontal direction.

[0012] Preferably, a reinforcing rib is provided between the horizontal plate and the vertical plate. By adopting the above solution, the connection strength between the horizontal plate and the vertical plate is improved.

[0013] Preferably, the frame further includes support legs disposed at the bottom of the work platform. Attached Figure Description

The vertical toothed plate 9 passes through the second through hole 14, and the bottom end of the vertical toothed plate 9 is fixedly connected to the pressure plate 4. The top of 5 is provided with a bearing seat 15, on which a transmission shaft 16 is rotatably connected. One end of the transmission shaft 16 is provided with a circular gear 17 that meshes with the vertical toothed plate 9, and the other end of the transmission shaft 16 is provided with a first bevel gear 18. The top end of the first rotating rod 10 is provided with a second bevel gear 19 that meshes with the first bevel gear 18. The first rotating rod 10 is provided with a first pulley 20, and the second rotating rod 11 is provided with a second pulley 21. A transmission belt 22 is connected between the first pulley 20 and the second pulley 21.

[0023] Furthermore, a product output conveyor belt 23 is provided below the work platform 1, and a material unloading channel 24 communicating with the first positioning groove 7 is provided at the bottom of the work platform 1. A push-pull channel 25 communicating with the first positioning groove 7 is provided inside the work platform 1. A movable carrier plate 26 is provided in the first positioning groove 7. One end of the movable carrier plate 26 extends into the push-pull channel 25, and the other end of the movable carrier plate 26 is inserted into the groove wall of the first positioning groove 7. A support groove for the movable carrier plate 26 to be inserted is provided on the groove wall of the first positioning groove 7. A push-pull drive cylinder is provided on the side of the work platform 1. The piston rod of the push-pull drive cylinder extends into the push-pull channel 25 and is fixedly connected to the movable carrier plate 26.

[0024] Furthermore, the second positioning groove 8 has an adsorption hole 28 on its groove wall, and the adsorption hole 28 is connected to an external negative pressure device through a flexible tube.

[0025] Furthermore, the elastic mechanism includes four springs 29 connected between the pressure plate 4 and the lifting plate 5, and the four springs 29 are arranged in a rectangular shape.

[0026] Furthermore, a guide rod 30 is inserted through the spring 29. The bottom end of the guide rod 30 is fixedly connected to the pressure plate 4, and the top end of the guide rod 30 passes through the lifting plate 5 and extends above the lifting plate 5.

[0029] When using the speaker assembly equipment of the present invention: the speaker is placed on the movable carrier plate 26 of the first positioning groove 7, and the bracket plate is placed in the second positioning groove 8. The bracket plate is fixed by adsorption through the adsorption hole 28. Then, screws are adsorbed onto the magnetic screwdriver heads 12 of the first rotating rod 10 and the second rotating rod 11 respectively. Then, the lifting drive mechanism 6 is started to run. The lifting drive mechanism 6 drives the lifting plate 5 to move downward. The lifting plate 5 drives the pressing plate 4 to move downward together until the pressing plate 4 moves downward to contact the working platform 1. The speaker and the bracket plate are pressed into the first positioning groove 7 and the second positioning groove 8 to form a speaker assembly. After that, the lifting drive mechanism 6 continues to drive the lifting plate 5 to move downward. The lifting plate 5 drives the first rotating rod 10 and the second rotating rod 12 to move downward together. Since the circular gear 17 meshes with the vertical toothed plate 9, the circular gear 17 will rotate when the lifting plate 5 moves downward. After rotation, the transmission shaft 16 will rotate, causing the transmission shaft 17 to drive the first rotating rod 10 to rotate through the meshing of the first bevel gear 18 and the second bevel gear 19. The first rotating rod 10 then drives the second rotating rod 11 to rotate synchronously through the transmission belt 22, so that the screws attracted by the magnetic screwdriver heads 12 on the first rotating rod 10 and the second rotating rod 11 pass through the first through hole 13 and are screwed into the bracket plate and the speaker, thus completing the fixed connection between the bracket plate and the speaker. Then, the piston rod 27 of the push-pull drive cylinder is activated to retract, thereby pulling the movable carrier plate 26 from the first positioning groove 7 into the push-pull channel 25. At this time, the speaker assembly will fall onto the product output conveyor belt 23 through the material drop channel 24 under its own gravity. The product output conveyor belt 23 will transport the received speaker assembly to the designated position. Finally, the lifting drive mechanism 6 and the push-pull drive cylinder are activated to reset, preparing for the next assembly operation.
