If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the invention based on the specific content of the technical solution.

[0043] Reference below Figures 1 to 5 The assembly device of the embodiment of the present invention is described. The assembly device includes a frame 100, a rotating seat assembly 300, a dispensing device and a conveying device 200; the rotating seat assembly 300 includes a rotating seat 330 and a damping component 320, the damping component 320 is arranged on the outer side of the rotating seat 330, and the damping component 320 rubs against the rotating seat 330; the dispensing device is fixedly arranged on the frame 100; the conveying device 200 is used to transport the rotating seat assembly 300 to the dispensing device.

[0044] The frame 100 includes an upper frame 120 and a lower frame 110, and the dispensing device is fixedly arranged on the upper frame 120. The rotating seat assembly 300 includes a rotating seat 330, a damping component 320 and a jig 310. The rotating seat 330 includes a rotating shaft 334, and a jig bearing tray 331 is arranged on the upper part of the rotating shaft 334. The jig bearing tray 331 is used to support the jig 310. The damping component 320 is arranged on the outer side of the jig bearing tray 331 for friction with the jig bearing tray 331. The damping component 320 is a cylindrical structure, and the outer surface of the damping component 320 is made of a flexible material. When the rotating seat is affected by an inertial force or a feeding operation force, the damping component 320 applies resistance to prevent the jig bearing tray 331 from rotating, so that the jig 310 on the jig bearing tray 331 is in a fixed state. It can be understood that the damping component 320 can also be made of a flexible material as a whole, and the flexible material can be rubber or urethane foam. The number of damping components 320 may be as follows: Figure 1The two shown in the figure, the number of damping components 320 can also be other numbers (for example, 3, 4, etc.), the damping components 320 are distributed on the periphery of the jig tray 331, and in order to evenly distribute the resistance on the jig tray 331, the damping components 320 are evenly distributed on the periphery of the jig tray 331. By setting the damping components 320, the jig tray 331 is fixed, and the rotating seat 330 is prevented from rotating after being subjected to inertia force or feeding operation force, thereby improving the quality of the product, and the damping components 320 have a simple structure and can reduce costs.

[0045] The dispensing device is fixedly arranged on the upper frame 120. Figure 1 As shown, the glue dispensing device includes a spring wave outer ring glue dispensing device 510, a spring wave center glue dispensing device 520, a drum paper outer ring glue dispensing device 530 and a drum paper center glue dispensing device 540.

[0046] The conveying device 200 is disposed on the outer side of the upper frame 120 , and the rotating seat 330 is fixedly disposed on the conveying device 200 . The conveying device 200 is used to transport the rotating seat assembly 300 to the dispensing device.

[0047] According to some specific embodiments of the present invention, Figures 1 to 5 As shown, the loudspeaker diaphragm assembly device further includes a first adjustment component 700, which includes a detection component 760 and a first driving member 750. The first driving member 750 can drive the rotating seat 330 to rotate. The rotating seat 330 also includes a positioning portion. The detection component 760 is arranged on the outer side of the rotating seat 330. When the detection component 760 detects the positioning portion, the first driving member 750 stops driving the rotating seat 330. Specifically, the first driving member 750 drives the rotating seat 330 to rotate. When the detection component 760 does not detect the positioning portion, the first driving member 750 drives the rotating seat 330 to rotate. When the detection component 760 detects the positioning portion, the first driving member 750 stops driving the rotating seat 330. The positioning of the rotating seat 330 is achieved through the cooperation of the detection component 760, the positioning portion and the first driving member 750.

[0048] In addition, the elastic wave center glue dispensing device 520 and the drum paper center glue dispensing device 540 need to dispense glue along a circular path. Usually, in order to achieve circular dispensing, the axes of the dispensing device need to cooperate with each other, and the movement is relatively complicated. In order to more easily dispense glue at the elastic wave center and the drum paper center, the dispensing head of the dispensing device can be fixed and cooperated with the rotation of the fixture to complete the dispensing of the elastic wave center and the drum paper center. The first adjustment component 700 is set at the workstation where the elastic wave center glue dispensing device 520 and the drum paper center glue dispensing device 540 are located, and is used to drive the rotation of the rotating seat 330 located at the workstation. In order to prevent interference between the first adjustment component 700 and the dispensing device, such as Figures 2 to 3As shown, the first adjustment assembly 700 is disposed on the lower frame 110. The dispensing operation of the center glue is completed by using the mutual cooperation of the dispensing device, the rotating seat 330, and the detection component 760, and the dispensing operation is simpler and the dispensing quality is more reliable.

[0049] During the dispensing operation of the elastic wave outer ring glue dispensing device 510 and the drum paper outer ring glue dispensing device 530, the jig needs to be positioned. Therefore, a first adjustment component 700 can be set at the work station where the elastic wave outer ring glue dispensing device 510 and the drum paper outer ring glue dispensing device 530 are located or at the previous work station to adjust the position of the rotating seat 330.

[0050] According to some specific embodiments of the present invention, during the dispensing operation of the elastic wave outer ring glue dispensing device 510 and the drum paper outer ring glue dispensing device 530, it is necessary to fix the rotating seat 330 at a specific position. However, the rotating seat 330 may still have a slight position deviation after being adjusted by the first adjustment component 700. In order to make the position of the rotating seat 330 more accurate, a second adjustment component 800 is provided at the station where the elastic wave outer ring glue dispensing device 510 and the drum paper outer ring glue dispensing device 530 are located. Figure 6 to Figure 7 As shown, the second adjustment assembly 800 includes a second linear drive member 810 and an adjustment arm 850. The second linear drive member 810 can drive the adjustment arm 850 to abut against or away from the positioning portion. Figure 6 The second linear drive member 810 shown includes a second base 820, a second guide rail 830, a second slider 840 and a second linear drive member 810. The second guide rail 830 is fixedly arranged on the second base 820, and the adjustment arm 850 is fixedly arranged on the second slider 840. The adjustment arm 850 is adjusted to contact or move away from the rotating seat 330 by telescoping the second linear drive member 810. The second linear drive member 810 can be a cylinder or a screw motor. When the adjustment arm 850 abuts against the positioning portion, the position of the rotating seat 330 can be further adjusted and the rotating seat 330 can be fixed at a desired position. Figures 1 to 3 As shown, in order to prevent the second adjusting component 800 from interfering with the glue dispensing device, the second adjusting component 800 is arranged on the lower frame 110, the elastic wave outer ring glue dispensing device 510 and the drum paper outer ring glue dispensing device 530 are arranged on the upper frame 120, and the positioning part of the rotating seat 330 is located below the upper frame 120. When the second adjusting component 800 adjusts the position of the rotating seat 330, it will not interfere with the glue dispensing device, which is beneficial to improve the coordination of the work of various components.

[0051] According to some specific embodiments of the present invention, Figures 4 to 5As shown, a positioning plate 332 is provided on the rotating seat 330, and the positioning plate 332 has a first side surface 3321 and a second side surface 3322. The first side surface 3321 is an arc-shaped surface, and the second side surface 3322 is a plane, and the second side surface 3322 is a positioning portion. The detection component 760 is a position sensor, which is arranged on the outer side of the positioning plate 332, and is used to detect the distance from the first side surface 3321 and the second side surface 3322 of the positioning plate 332 to the position sensor. The distance from the first side surface 3321 to the position sensor is different from the distance from the second side surface 3322 to the position sensor. When the second side surface 3322 of the positioning plate 332 is aligned with the position sensor, the first driving member 750 stops driving the rotating seat 330, and the rotating seat 330 stops at a fixed position.

[0052] According to some embodiments of the present invention, Figures 4 to 5 As shown, the output shaft 751 of the first driving member 750 is provided with a driving wheel 752, and the rotating seat 330 is provided with a driven wheel 333. The driving wheel 752 and the driven wheel 333 are driven by friction. Specifically, the structure of the driving wheel 752 and the driven wheel 333 can also be as follows Figure 4 The cylindrical shape shown may also be a conical wheel with two axes arranged in parallel. The frictional transmission of power between the driving wheel 752 and the driven wheel 333 can reduce the setting of the transmission structure and make the structure more compact.

[0053] According to some embodiments of the present invention, Figures 4 to 5 As shown, the first adjustment assembly 700 further includes a first linear drive member 710, which can drive the first drive member 750 to approach or move away from the rotating seat 330, so that the driving wheel 752 and the driven wheel 333 are in contact or separated, as shown in FIG. Figure 4-5 As shown, the first adjustment assembly 700 includes a first linear driving member 710, a first base 720, a first guide rail 730, a first slider 740 and a first driving member 750, wherein the first guide rail 730 is fixedly arranged on the first base 720, the first driving member 750 is fixed on the first slider 740, and the first linear driving member 710 drives the first slider 740 to move left and right along the first guide rail 730, so that the first driving member 750 moves left and right, realizing the contact or separation between the driving wheel 752 and the driven wheel 333, as shown in FIG. Figure 5As shown, the driving wheel 752 and the driven wheel 333 are in contact, and the first driving member 750 can drive the rotating seat 330 to rotate. When the position sensor detects the second side 3322 of the positioning plate 332, the first linear driving member 710 contracts and drives the first driving member 750 to move from right to left, so that the driving wheel 752 and the driven wheel 333 are separated, so that the rotating seat 330 stops at a fixed position. The first driving member 750 can be a cylinder or a screw motor. In order to further reduce the impact between the driving wheel 752 and the driven wheel 333 and increase the friction between the two, a layer of flexible material is coated on the surface of at least one of the driving wheel 752 and the driven wheel 333, and the flexible material can be rubber or urethane. By providing a flexible material, the friction coefficient between the two wheels can be increased, thereby increasing the friction between the two wheels and improving the transmission efficiency. In addition, the impact of the first adjustment component 700 on the rotating seat 330 can be reduced during the contact and separation of the driving wheel 752 and the driven wheel 333, and the stability of the rotating seat 330 can be maintained.

[0054] According to some specific embodiments of the present invention, Figure 1 to Figure 2 , Figures 8 to 9 As shown, it also includes a dust blowing and suction device 400, which is arranged on the upper frame 120 and in front of the workstation where the elastic wave outer ring glue dispensing device 510 is located. The dust blowing and suction device 400 first blows air to blow up the dust on the surface of the workpiece, and then sucks air to suck away the dust, thereby cleaning the dust on the surface of the workpiece on the fixture 310. The dust blowing and suction device 400 includes an air blowing pipe 410 and an air suction pipe 420. One end of the air blowing pipe 410 is connected to an external high-pressure air source. The suction port 421 of the air suction pipe 420 is opposite to the rotating seat 330. The suction port 422 of the air suction pipe 420 is connected to an external dust collecting part (not shown in the figure). The blowing port of the air blowing pipe 410 is aimed at the surface of the workpiece to blow up the dust on the surface of the workpiece. In order to prevent dust from polluting the entire production environment, after the air blowing pipe 410 blows up the dust on the surface of the workpiece, the suction device absorbs the dust. The dust enters the suction pipe 420 through the suction port 421 and enters the external dust collecting part through the suction port 422, thereby collecting the dust.

[0055] According to some specific embodiments of the present invention, Figures 8 to 9 The blowing pipe 410 is placed in the suction pipe 420, and the diameter of the suction pipe 420 is larger than the diameter of the blowing pipe 410. When inhaling, dust enters the suction pipe 420 through the gap between the suction pipe 420 and the blowing pipe 410 and is sucked away. By embedding the blowing pipe 410 in the suction pipe 420, the structure of the dust blowing and suction device 400 can be made more compact.

[0056] According to some specific embodiments of the present invention, Figure 2As shown, the dust blowing and suction device 400 further includes a lifting mechanism 430, and the suction pipe 420 is fixed on the lifting mechanism 430. The lifting mechanism 430 drives the suction pipe 420 to approach or move away from the rotating seat 330, so as to adjust the distance between the suction pipe 420 and the workpiece.

[0057] According to some specific embodiments of the present invention, after all dispensing operations are completed, the workpiece needs to be pressed to ensure the adhesion between the components, such as Figure 1 to Figure 2 As shown, it also includes a press device 600, which includes a pressure plate 610 and a vertical drive device 620. The press device 600 is set at the next station of the drum paper center glue dispensing device 540, and the rotating seat assembly 300 runs to the station where the press device 600 is located. The vertical drive device 620 drives the pressure plate 610 to move in the direction close to the rotating seat assembly 300 until it presses the workpiece on the rotating seat assembly 300. After the press is completed, the vertical drive device 620 drives the press device 600 to move upwards so that the rotating seat assembly 300 runs to the next station.
