Abstract
Description
Technical Field
[0001] The invention relates to the field of earphone assembly, and in particular to an earphone processing and assembling device. Background Art
[0002] The voice coil and diaphragm are both important parts for producing sound in headphones. The voice coil generates a magnetic field through the audio current of the headphones, which drives the diaphragm to vibrate and produce sound.
[0003] In the prior art, after the diaphragm is cut, the voice coil is installed on the center point of the diaphragm by judging the outer contour of the cut diaphragm.

As a result, the voice coil only corresponds to the center point of the outer contour of the diaphragm after installation, but has a certain deviation from the center point of the diaphragm.

[0030] The exhaust mechanism 8 also includes a reset ring 804, which is fixedly connected to one side of the support shell 1.

Two limit plates are fixedly connected to the inner wall of the reset ring 804, and one of the limit plates and the shifting plate 805 is connected by a fifth spring.
[0031] In the initial state, the positions of the first sliding frame 401 and the second sliding frame 501 are lower than the rotating sealing plate 803, and the first sliding frame 401 and the second sliding frame 501 are not at the bottom of the first slide groove; the diaphragm is placed under the annular suction cup 404, the bonding surface of the diaphragm faces upward and the bonding part is coated with UV glue, the voice coil is placed under the soft glue claw 508, the driving motor 601 is started, and the output shaft of the driving motor 601 rotates to drive the driving pulley of the belt transmission group 602, so that the driving pulley controls the rotation of the driven pulley through the transmission belt, and the driving slide The column 603 moves synchronously, and the sliding column 603 slides horizontally in the second slider 604 while moving, and squeezes the second slider 604 to move downward along the fifth slide groove. When the second slider 604 moves, it drives the cylindrical connecting rod 606 to move through the first rotating column 605, so that the cylindrical connecting rod 606 controls the movement of the first mounting plate 608 through the second rotating column 607. The first mounting plate 608 drives the first sliding frame 401 and the second sliding frame 501 to move downward along the first slide groove, thereby realizing the driving mechanism 6 to drive the suction cup mechanism 4 and the clamping claw mechanism 5.
[0032] During the downward movement of the first sliding frame 401, the movement of the first sliding frame 401 causes the coil spring 402 to drive the buffer frame 403 to move downward, and the buffer frame 403 moves through the first spring to drive the annular suction cup 404 to move downward until the annular suction cup 404 contacts the edge of the diaphragm. At this time, the first sliding column of the first sliding frame 401 has not slid to the bottom end of the first sliding groove, and the first sliding frame 401 continues to slide, and the annular suction cup 404 presses the first spring upward to compress the first spring. At the same time, the compression of the first spring acts on the buffer frame 403, causing the buffer frame 403 to slide. The sliding of the buffer frame 403 causes the coil spring 402 to drive the buffer frame 403 to slide. The spring 402 is deformed and bent, and during this process, the movement of the first sliding frame 401 drives the second mounting plate 704 to move synchronously, and the second mounting plate 704 moves away from the first air storage shell 701, so that the telescopic connecting rod 702 between the two is elongated, and drives the first air storage shell 701 and the third rotating column 703 to rotate. The telescopic connecting rod 702 is elongated, which increases the volume of the gas in the first air storage shell 701 and reduces the pressure, thereby causing the first air storage shell 701 to inhale air to the annular suction cup 404 through the first one-way valve 705 and the first hose. The air pressure in the annular suction cup 404 is reduced, causing the annular suction cup 404 to generate suction to adsorb the diaphragm.
[0033] During the downward movement of the second sliding frame 501, the second sliding frame 501 drives the cone rod 502, the installation cylinder 505 and the curing lamp 503 to move synchronously, and drives the extrusion frame 504 to move synchronously through the second spring. At the same time, the installation cylinder 505 drives the soft rubber claw 508 to extend into the voice coil through the first slider 507 until the ball 5042 contacts the plane of the voice coil and remains stationary. If the extrusion rod 5041 on the side wall of the extrusion frame 504 touches the voice coil during the falling process, since the mass of the voice coil is only a few milligrams to tens of milligrams, the extrusion The squeezing rod 5041 on the side wall of the pressing frame 504 can squeeze the terminal of the voice coil through the arc surface, so that the terminal of the voice coil undergoes slight elastic deformation and causes a small displacement of the voice coil, thereby preventing the voice coil from being squeezed by the squeezing rod 5041 and undergoing plastic deformation and causing damage; the second sliding frame 501 continues to move downward, so that the second sliding frame 501 squeezes the second spring, and at the same time the limiting rod 506 is squeezed by the limiting groove 5021, thereby sliding along the third sliding groove of the mounting tube 505, and the cone rod 502 is affected by the reaction force to rotate, according to the attached Figure 6 As shown, the limit rod 506 is initially located at position A in the figure, and will move toward position B when the second sliding frame 501 moves downward. The second sliding frame 501 slides downward to drive the cone rod 502 to squeeze the chamfer of the first slider 507, so that the first slider 507 slides along the fourth slide groove. The first slider 507 compresses the third spring and drives the soft rubber claw 508 to fit and squeeze the inner side of the voice coil, so as to achieve the gripping of the voice coil. In the process of the soft rubber claw 508 fitting and squeezing the inner side of the voice coil, the soft rubber claw 508 will fully contact the inner side of the voice coil, so that the axis of the voice coil moves toward the axis of the soft rubber claw 508, so as to achieve the position correction of the voice coil during gripping.
[0034] After the diaphragm is adsorbed and the voice coil is grasped, the slide column 603 is located at the bottom of the active pulley of the belt drive group 602, and the output shaft of the driving motor 601 continues to rotate the drive belt of the belt drive group 602, so that the drive belt rotates around the active pulley and the driven pulley, driving the slide column 603 to start moving upward. The movement of the slide column 603 controls the movement of the first rotating column 605 through the second slider 604, and controls the second rotating column 607 through the cylindrical connecting rod 606 to drive the first mounting plate 608 to move, so that the first mounting plate 608 drives the first sliding frame 401 and the second sliding frame 501 to move upward along the first sliding groove, and the voice coil and the diaphragm are lifted up to prepare for the next step of fixation.
[0035] In the process of the first sliding frame 401 moving upward, on the one hand, the movement of the first sliding frame 401 causes the second mounting plate 704 to drive the third rotating column 703 to move, so that the telescopic connecting rod 702 is shortened. At the same time, the third rotating column 703 and the first gas storage shell 701 rotate, and the telescopic connecting rod 702 is shortened, so that the volume of the gas in the first gas storage shell 701 becomes smaller and the pressure becomes larger. The gas is discharged through the second one-way valve 706. When the first sliding frame 401 moves from below the first gas storage shell 701 to above it, the first sliding frame 401 moves upward. The movable frame 401 moves the third rotating column 703 through the second mounting plate 704, thereby lengthening the telescopic connecting rod 702. At this time, the volume of gas in the first gas storage shell 701 increases, and the pressure decreases, so that the first one-way valve 705 further inhales air to the annular suction cup 404 through the first hose, and the adsorption of the diaphragm is further strengthened; on the other hand, when the second rotating column 607 moves upward, it touches and pushes the rotating sealing plate 803, so that the rotating sealing plate 803 drives the second gas storage shell 802 and the shifting column 801 to move in the reset ring 80 4, when the lever 801 rotates, the lever plate 805 on one side thereof squeezes the fifth spring, so that the fifth spring is compressed. When the second rotating column 607 is separated from the rotating sealing plate 803, the fifth spring is released and pushes the lever 801 to rotate and reset through the lever plate 805. The rotation of the lever 801 drives the second gas storage shell 802 and the rotating sealing plate 803 to rotate synchronously to achieve reset. When the first sliding frame 401 slides to the corner of the first sliding groove, the first sliding column on its side passes the corner in the first sliding groove in turn. When the first sliding frame 401 moves, it rotates counterclockwise, so that the bonding surface of the diaphragm faces the clamping mechanism 5; when the second sliding frame 501 moves upward, the second sliding frame 501 drives the cone rod 502 to move upward and releases the second spring, and the limiting groove 5021 squeezes the limiting rod 506 along the axial direction of the cone rod 502, so that the limiting rod 506 slides in the limiting groove 5021, thereby driving the cone rod 502 to rotate, and at the same time, the limiting rod 506 slides downward in the first limiting track 5022 until it slides to Figure 6 At C of the first limiting track 5022, the limiting rod 506 is located at the connection between the first limiting track 5022 and the second limiting track 5023, and the first slider 507 is still in contact with the cylindrical surface of the cone rod 502, and the soft rubber claw 508 always clamps the voice coil; when the second sliding frame 501 slides to the corner of the first slide groove, the third sliding column on one side moves and slides into the short groove, and then the second sliding column passes the corner in the first slide groove, and the third sliding column moves horizontally with the second sliding frame 501 to slide out of the short groove, and moves horizontally along the herringbone slide groove 301, and the second sliding frame 501 rotates counterclockwise, so that the bonding surface of the voice coil faces the diaphragm.
[0036] The driving mechanism 6 continues to drive the suction cup mechanism 4 and the clamping claw mechanism 5 to approach each other. As the extrusion frame 504 slides into the inner side of the annular suction cup 404 and the ball 5042 contacts the protrusion of the diaphragm, it is worth noting that the protrusion of the diaphragm is spherical or annular. If the diaphragm is not on the same axis as the voice coil, only part of the ball 5042 contacts the protrusion of the diaphragm. As the clamping claw mechanism 5 continues to move, the ball 5042 squeezes the protrusion of the diaphragm, and the center of the protrusion of the diaphragm moves toward the axis of the cone rod 502, thereby causing the other part of the ball that is not in contact with the diaphragm to move. The protrusions of the diaphragm 5042 are close to the diaphragm. Since the ball 5042 moves on the diaphragm by rolling rather than sliding, the ball 5042 will not scratch the diaphragm, thereby preventing the diaphragm from being damaged during assembly. Until all the ball 5042 fit with the protrusions of the diaphragm, at this time, the protrusion center of the diaphragm and the voice coil are on the same axis. When the diaphragm is squeezed and moves axially, the annular suction cup 404 absorbs the diaphragm, so that the diaphragm drives the annular suction cup 404 to move synchronously. The movement of the annular suction cup 404 drives the buffer frame 403 to move through the first spring, and the buffer frame 403 moves. 03 movement will also squeeze the coil spring 402 to deform it, so that the coil spring 402 and the first spring absorb the pressure generated by the axial movement of the diaphragm. At the same time, the diaphragm will move radially when squeezed. The radial movement of the diaphragm drives the buffer frame 403 to move synchronously through the annular suction cup 404, so that the buffer frame 403 radially squeezes the coil spring 402, causing the coil spring 402 to deform radially, thereby achieving radial positioning and calibration of the diaphragm and the coil spring 402, so that the diaphragm and the voice coil are on the same axis, avoiding the judgment of the voice coil only by the outer contour of the diaphragm when installing the voice coil. The eccentricity problem caused by the position; then the second slider 604 slides to the top of the fifth slide groove, at this time the slide post 603 is located at the top of the driven pulley of the belt drive group 602, and the first slide post of the first slide frame 401 slides to one end of the first slide groove, and the third slide post of the second slide frame 501 slides to one end of the herringbone slide groove 301. In this process, the second slide frame 501 drives the cone rod 502 to move synchronously and compress the second spring, so that the limit rod 506 slides in the second limit track 5023. When the limit rod 506 slides to Figure 6 When at D of the second limiting track 5023, the cylinder of the cone rod 502 slides along the first slider 507. Since the first slider 507 always contacts the outer wall of the cylinder of the cone rod 502, the first slider 507 does not slide radially to squeeze the third spring. Instead, the voice coil is clamped by the soft glue claws 508 to contact the UV glue coated on the diaphragm. Then, the driving motor 601 is stopped and the curing lamp 503 is started to cure the UV glue to bond the diaphragm and the voice coil, thereby achieving the installation of the voice coil.
[0037] When the UV glue is completely cured, turn off the curing lamp 503 and continue to start the driving motor 601, so that the output shaft of the driving motor 601 drives the sliding column 603 to move downward through the belt transmission group 602, and then the sliding column 603 drives the second sliding block 604 to slide downward along the fifth sliding groove, and the second sliding block 604 slides through the first rotating column 605 to move the cylindrical connecting rod 606, and the cylindrical connecting rod 606 moves through the second rotating column 607 to push the first mounting plate 608, so that the suction cup mechanism 4 and the clamping claw mechanism 5 begin to separate from each other and slide downward along the first sliding groove. During the separation process, the second sliding frame 501 is pulled away from the suction cup mechanism 4 by the first mounting plate 608, and drives the cone rod 502 to slide synchronously, the second spring is released, and the limiting rod 506 slides in the second limiting track 5023 of the limiting groove 5021. It is worth noting that point A is the connection between the first limiting track 5022 and the second limiting track 5023. When the limiting rod 506 slides to Figure 6 When the first limit track 5022 is at point A, the cylindrical surface of the cone rod 502 is separated from the first slider 507, so that the third spring pushes the first slider 507 to contact the frustum of the cone rod 502, and the first sliders 507 approach each other to make the soft rubber claws 508 release the voice coil. As the second sliding frame 501 moves, the second spring pulls the extrusion frame 504 away from the diaphragm and no longer squeezes the terminal of the voice coil, and the terminal of the voice coil recovers its shape. At this time, the coil spring 402 and the first spring of the suction cup mechanism 4 are released and reset. At the same time, the suction cup mechanism 4 and the clamping jaw mechanism 5 are separated, and the suction mechanism 7 restarts the above-mentioned exhaust action of the first air storage shell 701.
[0038] When the first sliding frame 401 slides to the corner of the first slide groove, the two first sliding posts on its side successively pass the corner in the first slide groove, so that the first sliding frame 401 rotates clockwise during movement, so that the bonding surface of the diaphragm faces upward again; when the second sliding frame 501 slides to the corner of the first slide groove, the third sliding post on one side moves and slides into the short groove, and then the second sliding post passes the corner in the first slide groove, and the third sliding post moves vertically with the second sliding frame 501 to slide out of the short groove and move along the herringbone slide groove 301, and the second sliding frame 501 rotates clockwise to complete the direction reset of the clamping mechanism 5; when the first sliding frame 401 slides to the first air storage shell 701 and continues to move downward, the second sliding post When the column 607 moves, it will touch and push the rotating sealing plate 803, causing the rotating sealing plate 803 to rotate on the second air storage shell 802. At this time, the third air inlet of the second air storage shell 802 is opened, and the gas enters the second air storage shell 802 and enters the annular suction cup 404 through the second hose, so that the air pressure in the annular suction cup 404 gradually recovers and loosens the diaphragm. Since the diaphragm is flat, it keeps the voice coil upward and falls on the platform. When the rotating sealing plate 803 is separated from the second rotating column 607, the fourth spring recovers and pushes the rotating sealing plate 803 to seal the third air inlet of the second air storage shell 802. At this time, the driving motor 601 is stopped to complete the resetting of the device, or the driving motor 601 is started again to enable the equipment to perform assembly line tasks.
