Description

Technical Field

[0001] The present invention relates to the technical field of glue coating equipment, and more specifically to a voice coil glue coating equipment for loudspeaker production. Background Art

[0002] A loudspeaker, commonly known as a "horn", is a transducer device that converts electrical signals into acoustic signals. It can be found in all electronic and electrical equipment that make sound. The performance of the loudspeaker has a great impact on the sound quality. The loudspeaker is the weakest device in audio equipment, but for sound effects, it is the most important component. The direct definition of a voice coil is a coil through which current passes. It is an important part of the mechanical wave system of an electric loudspeaker, and can also be said to be the heart of the loudspeaker. The performance of the voice coil will affect the sound intensity characteristics, sound intensity level, impedance curve, distortion, transient characteristics, loudspeaker parameters, sound quality, etc. of the loudspeaker, especially the power handling and life of the loudspeaker. In the loudspeaker Glue coating equipment is needed in the processing of voice coils. The glue coating equipment is generally a glue dispensing machine, also known as a glue coating machine, which is an automated machine that specializes in controlling fluids and drips and applies fluids to the surface or inside of products. The glue dispensing machine is mainly composed of a control system, a manipulator system, a pressurization system and a glue dispensing valve. The control system is usually composed of a computer, a controller, etc. The manipulator system is responsible for completing the clamping and positioning of the product, and is generally composed of a stepper motor, a reducer, a servo motor, a travel switch, a controller, etc. The pressurization system is responsible for providing the driving force of the glue, and is mainly composed of a pneumatic pump, a pressure sensor, a pressure controller, a glue barrel, etc. The glue dispensing valve is responsible for the output and control of the glue.

[0003] The shortcomings of existing voice coil gluing equipment: Voice coil gluing generally requires brushing glue on the copper wire wrapped around the outside of the voice coil. After gluing, it is necessary to wait for the glue to solidify naturally before removing it from the fixture. Since the glue needs to be applied on the copper wire, a certain glue thickness is required, so the time required for natural air drying is long, and the applied glue is also easily affected by gravity, resulting in poor effect; secondly, when the gluing is completed, there will be residual glue attached to the glue head, and the residual glue is likely to affect the next gluing.

The top of the bracket base 601 is fixedly connected with the sliding vertical rod 602, the top of the sliding vertical rod 602 is fixedly connected with a connecting plate 603 that plays a limiting role, the outer side of the sliding vertical rod 602 is movably connected with a first sliding block 604 with bolts to adjust the tightness, the top middle part of the first sliding block 604 is movably connected with a threaded rod 605, the bottom of the threaded rod 605 passes through the first sliding block 604, and the top is fixedly connected with an adjusting handle 606, and the outer side of the threaded rod 605 is threadedly connected to the connecting plate 603 near the top; A sliding hole is provided on one side of the front face of the first sliding block 604, and a sliding longitudinal rod 607 is movably sleeved in the sliding hole, a second sliding block 608 is movably connected to the outer side of the sliding longitudinal rod 607, sliding holes for connecting the glue valve mechanism 7 are provided on the top of both sides of the second sliding block 608, a screw handle 609 is movably connected to the middle part of the front face of the second sliding block 608, a connecting block 610 is threadedly connected to the outer side of the screw handle 609, and the connecting block 610 is fixedly mounted on the first sliding block 604.

[0033] Reference Fig.10 The glue valve mechanism 7 includes a sliding cross bar 701, a mounting block 702, a glue valve cylinder 703, a mounting frame 704, a syringe 705 and a glue head 706. One side of the sliding cross bar 701 is fixedly connected to the mounting block 702, and the other side of the sliding cross bar 701 is fixedly installed inside the second sliding block 608 by bolts. The top of the mounting block 702 is fixedly connected to the glue valve cylinder 703, and the push cover of the glue valve cylinder 703 is fixedly connected to the mounting frame 704. The syringe 705 is fixedly installed inside the mounting frame 704, and the glue head 706 is fixedly installed on the end of the syringe 705.

[0034] The working principle of the present invention is as follows: when in use, the voice coil is placed in the center of the fixture table 4, and the knob 505 is turned to make the worm 501 rotate with the bearing 504 as the rotation point. Since the transmission member 506 is meshed with the worm wheel, when the worm 501 rotates, the transmission gear 5064 moves on the worm wheel, and the transmission gear 5064 rotates on the rotating rod 5063, driving the gear frame 5061 to move, and then driving the clamping block 406 fixed to the connecting slider 5062 to move. Since the right-handed worm wheel 502 and the left-handed worm wheel 503 rotate in opposite directions, the transmission member 506 meshed with them moves toward or in the opposite direction, so that the displacement of the clamping block 406 fixed on the top of the transmission member 506 is consistent, so the opposite directions When the clamping block 406 moves in the first slide groove 404, the displacement is consistent, so that the voice coil is quickly clamped. Then, by rotating the adjusting handle 606, the threaded rod 605 is threadedly rotated relative to the connecting plate 603, thereby driving the first sliding block 604 to move on the sliding vertical rod 602, and adjusting the height of the first sliding block 604. After the adjustment is completed, the bolts are tightened to prevent the first sliding block 604 from moving. By rotating the screw handle 609, it is moved relative to the connecting block 610, thereby driving the second sliding block 608 to move on the sliding longitudinal rod 607, and adjusting the position of the glue valve mechanism 7 installed thereon relative to the clamping table 4 in the longitudinal direction. According to the size of the voice coil, the angle of the glue valve mechanism 7 can be adjusted, and the rotation The sliding crossbar 701 changes the angle of the mounting block 702, and then adjusts the angle of the glue head 706. After the angle adjustment is completed, the bolts are tightened to clamp the sliding crossbar 701 with the second sliding block 608. When applying glue, the glue valve cylinder 703 pushes the syringe 705 to move, so that the glue head 706 is applied to the voice coil. At the same time, the fan 205 draws air through the air inlet 202 of the bellows 201. After being heated by the temperature-adjustable heater 203, the hot air is blown out from the air outlet 206 and guided by the exhaust duct 207 to the glue application point, so that the glue on the copper wire wrapped around the outer side of the voice coil is accelerated to solidify, the time for the glue to solidify is reduced, and the unsolidified glue is prevented from sliding downward under the influence of gravity. The second motor 4 03 cooperates with the reducer 402, so that the working mode of the rotating disk 401 can be made to rotate continuously or stop after rotating a certain angle, so that it can adapt to different situations of voice coil copper wire winding when applying glue. When a little glue remains on the glue head 706 after gluing, the residual glue becomes a semi-solidified state after being accelerated to solidify by the air-drying mechanism 2. The connecting frame 303 is pushed to move to the oblique lower side of the glue head 706 by the glue removal cylinder 302, and the first motor 305 drives the rotating cylinder 306 and the glue removal cylinder brush 307 to rotate. The glue valve cylinder 703 pushes the glue head 706 to contact the bristles 308 on the glue removal cylinder brush 307, and the rotating bristles 308 brush off the semi-solidified glue to prevent the residual glue from affecting the subsequent gluing.

[0035] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
