[0027] It further includes an air suction mechanism 7. The air suction mechanism 7 includes a first air storage shell 701. One side outside the frame 1 is rotatably connected to the first air storage shell 701. One side of the first air storage shell 701 is fixedly connected to a telescopic connecting rod 702 in a sealed manner. The telescopic connecting rod 702 is of a hollow structure. One end of the telescopic connecting rod 702 is provided with a third rotating column 703. One end of the third rotating column 703 is rotatably connected to a second mounting plate 704. The second mounting plate 704 is fixedly connected to the two first sliding columns of the first sliding frame 401. The outer wall of the first air storage shell 701 is provided with a first air inlet and a second air outlet. A first one-way valve 705 is fixedly connected in the first air inlet.

[0028] It further includes an exhaust mechanism 8. The exhaust mechanism 8 includes a dialing column 801. One side of the frame 1 is rotatably connected to the dialing column 801.

[0029] The exhaust mechanism 8 further includes a reset ring 804. The reset ring 804 is fixedly connected to one side of the frame 1. The dialing column 801 is located inside the reset ring 804.

A fifth spring is connected between one of the limiting plates and the dialing plate 805.

[0030] In the initial state, the positions of the first sliding frame 401 and the second sliding frame 501 are lower than that of the rotating sealing plate 803, and neither the first sliding frame 401 nor the second sliding frame 501 is at the bottom end of the first sliding groove; place the diaphragm under the annular suction cup 404, with the bonding surface of the diaphragm facing upward and the bonding part coated with UV glue, place the voice coil under the soft rubber claw 508, start the drive motor 601, the output shaft of the drive motor 601 rotates to drive the driving pulley of the belt transmission group 602, so that the driving pulley controls the driven pulley to rotate through the transmission belt, and synchronously moves the driving slide column 603. While moving, the slide column 603 horizontally slides within the second slider 604, and squeezes the second slider 604 to move downward along the fifth sliding 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 sliding groove, realizing the drive of the suction cup mechanism 4 and the jaw mechanism 5 by the drive mechanism 6.

[0031] 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. The movement of the buffer frame 403 drives the annular suction cup 404 to move downward through the first spring 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 yet slid to the bottom end of the first sliding groove. The first sliding frame 401 continues to slide, and the annular suction cup 404 squeezes the first spring upward, causing the first spring to compress. At the same time, the extrusion force received by 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 deform and bend. During this process, the movement of the first sliding frame 401 drives the second mounting plate 704 to move synchronously. The second mounting plate 704 moves away from the first air storage shell 701, stretching the telescopic connecting rod 702 between the two, and driving the first air storage shell 701 and the third rotating column 703 to rotate. The stretching of the telescopic connecting rod 702 makes the volume of the gas in the first air storage shell 701 increase and the pressure decrease. Furthermore, the first air storage shell 701 inhales air into 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 decreases, causing the annular suction cup 404 to generate suction to adsorb the diaphragm.

[0032] During the downward movement of the second sliding bracket 501, the second sliding bracket 501 drives the tapered rod 502, the mounting cylinder 505, and the curing lamp 503 to move synchronously, and drives the extrusion bracket 504 to move synchronously through the second spring. At the same time, the mounting cylinder 505 drives the soft rubber jaw 508 to extend into the voice coil through the first slider 507 until the ball 5042 contacts the plane of the voice coil and then remains stationary. If the extrusion rod 5041 on the side wall of the extrusion bracket 504 touches the voice coil during the falling process, since the mass of the voice coil is only a few milligrams to dozens of milligrams, the extrusion rod 5041 on the side wall of the extrusion bracket 504 can extrude the wiring terminal of the voice coil through the arc surface, causing slight elastic deformation of the wiring terminal of the voice coil and causing a small displacement of the voice coil, preventing the voice coil from being damaged due to plastic deformation caused by the extrusion of the extrusion rod 5041; the second sliding bracket 501 continues to move downward, causing the second sliding bracket 501 to squeeze the second spring, and at the same time, the limiting rod 506 is squeezed by the limiting groove 5021, so as to slide along the third sliding groove of the mounting cylinder 505, and the tapered rod 502 rotates under the influence of the reaction force. According to the attached Figure 6 As shown, the limiting rod 506 is initially located at the position A in the figure. When the second sliding bracket 501 moves downward, it will move towards the position B. The downward sliding of the second sliding bracket 501 drives the tapered rod 502 to squeeze the chamfer of the first slider 507, causing the first slider 507 to slide along the fourth sliding groove. The first slider 507 compresses the third spring and drives the soft rubber jaw 508 to fit and squeeze the inner side of the voice coil, realizing the grasping of the voice coil. During the process of the soft rubber jaw 508 fitting and squeezing the inner side of the voice coil, the soft rubber jaw 508 will fully contact the inner side of the voice coil, causing the axis of the voice coil to move towards the axis of the soft rubber jaw 508, realizing the position correction of the voice coil during grasping.

[0033] After realizing the adsorption of the diaphragm and the grasping of the voice coil, at this time, the sliding column 603 is located at the bottom of the driving pulley of the belt transmission group 602. The output shaft of the driving motor 601 continues to rotate to drive the transmission belt of the belt transmission group 602, so that when the transmission belt rotates around the driving pulley and the driven pulley, it drives the sliding column 603 to start moving upward. The movement of the sliding column 603 controls the movement of the first rotating column 605 through the second slider 604, and controls the second rotating column 607 to drive the first mounting plate 608 to move through the cylindrical connecting rod 606, so that the first mounting plate 608 drives the first sliding bracket 401 and the second sliding bracket 501 to move upward along the first sliding groove, and the voice coil and the diaphragm are lifted to prepare for the next fixation.

[0034] During the upward movement of the first sliding carriage 401, on the one hand, the movement of the first sliding carriage 401 causes the second mounting plate 704 to drive the third rotating column 703 to move, shortening the telescopic connecting rod 702. At the same time, the third rotating column 703 and the first gas storage shell 701 rotate. The shortening of the telescopic connecting rod 702 reduces the gas volume in the first gas storage shell 701, increasing the pressure. The gas is discharged through the second one-way valve 706. When the first sliding carriage 401 moves from below the first gas storage shell 701 to above it, the first sliding carriage 401 moves the third rotating column 703 through the second mounting plate 704, thereby stretching the telescopic connecting rod 702. At this time, the gas volume in the first gas storage shell 701 increases and the pressure decreases, causing the first one-way valve 705 to further inhale air from the first hose into the annular suction cup 404, further strengthening the adsorption of the diaphragm. On the other hand, when the second rotating column 607 moves upward, it touches and pushes the rotating sealing plate 803, causing the rotating sealing plate 803 to drive the second gas storage shell 802 and the dialing post 801 to rotate within the reset ring 804. When the dialing post 801 rotates, the dialing plate 805 on one side of it presses the fifth spring, compressing the fifth spring. When the second rotating column 607 disengages from the rotating sealing plate 803, the fifth spring releases and drives the dialing post 801 to rotate and reset through the dialing plate 805. The rotation of the dialing post 801 drives the second gas storage shell 802 and the rotating sealing plate 803 to rotate synchronously to achieve reset. When the first sliding carriage 401 slides to the corner of the first chute, the first sliding column on its side sequentially passes through the corner in the first chute, causing the first sliding carriage 401 to rotate counterclockwise during movement, making the bonding surface of the diaphragm face the jaw mechanism 5. During the upward movement of the second sliding carriage 501, the second sliding carriage 501 drives the tapered rod 502 to move upward and releases the second spring. The limiting groove 5021 axially presses the limiting rod 506 along the tapered rod 502, causing the limiting rod 506 to slide within the limiting groove 5021, thereby driving the tapered rod 502 to rotate. At the same time, the limiting rod 506 slides downward within the first limiting track 5022 until it slides to Figure 6 point C of the first limiting track 5022 in Figure 6 . At this time, the limiting rod 506 is located at the connection of the first limiting track 5022 and the second limiting track 5023, and the first slider 507 still contacts the cylindrical surface of the tapered rod 502. The soft rubber jaw 508 always clamps the voice coil. When the second sliding carriage 501 slides to the corner of the first chute, the third sliding column on one side of it moves into the short groove. Then the second sliding column passes through the corner in the first chute, and the third sliding column horizontally moves out of the short groove along with the horizontal movement of the second sliding carriage 501 and moves horizontally along the herringbone chute 301. The second sliding carriage 501 rotates counterclockwise, making the bonding surface of the voice coil face the diaphragm.

[0035] The driving mechanism 6 continues to drive the suction cup mechanism 4 and the jaw 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 should be noted 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 balls 5042 will contact the protrusion of the diaphragm. As the jaw mechanism 5 continues to move, the balls 5042 squeeze the protrusion of the diaphragm, and the center of the protrusion of the diaphragm will move towards the axis of the cone rod 502, thereby causing the other part of the balls 5042 that do not contact the diaphragm to approach the protrusion of the diaphragm. Since the balls 5042 move on the diaphragm in a rolling rather than a sliding manner, the balls 5042 will not scratch the diaphragm, avoiding damage to the diaphragm during assembly until all the balls 5042 are in contact with the protrusion of the diaphragm. At this time, the center of the protrusion of the diaphragm is on the same axis as the voice coil. When the diaphragm is axially moved by extrusion, since the annular suction cup 404 adsorbs the diaphragm, 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. The movement of the buffer frame 403 will also squeeze the coil spring 402 to deform it, realizing that the coil spring 402 and the first spring absorb the pressure generated by the axial movement of the diaphragm. At the same time, when the diaphragm is squeezed, it will undergo a radial movement. The radial movement of the diaphragm drives the buffer frame 403 to move synchronously through the annular suction cup 404, and then the buffer frame 403 radially squeezes the coil spring 402, causing the coil spring 402 to undergo a radial deformation, thereby realizing the 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 eccentricity problem caused by only relying on the outer contour of the diaphragm to judge the position during the installation of the voice coil; then the second slider 604 slides to the top of the fifth chute. At this time, the sliding column 603 is located at the top of the driven pulley of the belt drive group 602, and the first sliding column of the first sliding frame 401 slides to one end of the first chute, and the third sliding column of the second sliding frame 501 slides to one end of the herringbone chute 301. During this process, the second sliding frame 501 drives the cone rod 502 to move synchronously and compress the second spring, causing the limit rod 506 to slide in the second limit track 5023. When the limit rod 506 slides to Figure 6 point D of the second limit track 5023 in the middle, 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 undergo a radial sliding to squeeze the third spring, but clamps the voice coil through the soft rubber claw 508 and contacts the UV glue application area on the diaphragm. Subsequently, the driving motor 601 is stopped and the curing lamp 503 is started to cure the UV glue to adhere the diaphragm and the voice coil, realizing the installation of the voice coil.

[0036] 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. Furthermore, the sliding column 603 drives the second slider 604 to slide downward along the fifth chute. The second slider 604 slides to move the cylindrical connecting rod 606 through the first rotating column 605. The cylindrical connecting rod 606 moves to push the first mounting plate 608 through the second rotating column 607, so that the suction cup mechanism 4 and the jaw mechanism 5 start to separate from each other and slide downward along the first chute. 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 tapered rod 502 to slide synchronously. The second spring is released and the limiting rod 506 slides within the second limiting track 5023 of the limiting groove 5021. It should be noted that point A is the connection point of the first limiting track 5022 and the second limiting track 5023. When the limiting rod 506 slides to Figure 6 point A of the first limiting track 5022 in Figure 6 , the cylindrical surface of the tapered 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 tapered rod 502. The first sliders 507 approach each other to loosen the voice coil by the soft rubber claws 508. 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. The terminal of the voice coil resumes its shape. At this time, the coil spring 402 and the first spring of the suction cup mechanism 4 are released and reset. While the suction cup mechanism 4 and the jaw mechanism 5 are separated, the air suction mechanism 7 restarts the above-mentioned action of exhausting the first air storage shell 701.

[0037] When the first sliding frame 401 slides to the corner of the first sliding groove, the two first sliding columns on its side sequentially slide through the corner in the first sliding groove, causing the first sliding frame 401 to rotate clockwise during movement, and making the bonding surface of the diaphragm face upward again; when the second sliding frame 501 slides to the corner of the first sliding groove, the third sliding column on one side of it moves and slides into the short groove, and then the second sliding column slides through the corner in the first sliding groove, the third sliding column moves vertically out of the short groove along with the second sliding frame 501 and moves along the herringbone sliding groove 301, and the second sliding frame 501 rotates clockwise to complete the direction reset of the jaw mechanism 5; when the first sliding frame 401 slides to the first air storage shell 701 and continues to move downward, the second rotating column 607 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 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 releases the diaphragm. Due to its flat shape, the diaphragm 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 reset of the device, or the driving motor 601 is continued to be started to make the device perform the pipeline task.
