DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings, but the embodiments described by the present application are part of the embodiments of the present application, not all the embodiments.

[0024] As shown in the drawings, Figures 1-5 The present embodiment provides a sound film sealing ring mounting device, which comprises a conveying assembly 10, a transfer mounting assembly 20 and the like.

[0025] Specifically, as shown in the drawings, Figures 1-2 , Figure 5 The conveying assembly 10 comprises a first conveying belt 11, an assembling table 12 and a second conveying belt 13. The first conveying belt 11 is used for conveying sound films 1 in sequence, and the second conveying belt 13 is used for conveying sealing rings 2. The assembling table 12 is arranged at the end of the conveying direction of the first conveying belt 11 and the second conveying belt 12, and is used for providing a platform for the assembly of the sound film 1 and the sealing ring 2. That is to say, the second conveying belt 13 is located on one side of the assembling table 12, and the conveying direction of the second conveying belt 13 is perpendicular to the conveying direction of the first conveying belt 11. In order to make each sound film 1 entering the assembling table 12 at the same position during assembly, a circular structure containing groove is arranged on the assembling table 12, and a sucking disc 121 is arranged in the containing groove, so that the sound film 1 entering the containing groove is kept concentric with the containing groove, and then the bottom plane of the sound film 1 is adsorbed by the sucking disc 12, so as to realize the fixation of the sound film 1.

[0026] The end of the conveying direction of the second conveying belt 13 is provided with an arc-shaped groove 131, and the arc of the arc-shaped groove 131 is arranged opposite to the conveying direction of the second conveying belt 13, so as to limit the sealing ring 2 at the front end of the conveying direction of the second conveying belt 13, so that the sealing ring 2 entering the arc-shaped groove 131 is concentric with the arc-shaped groove 131.

[0027] As shown in the drawings, Figures 1-3As shown, the transfer installation assembly 20 includes a crossbeam 21, a telescopic rod 22, an installation plate 23, an installation cylinder 24, a material taking piece 25, and a pressing ring 26. The crossbeam 21 is arranged vertically above the center of the arc-shaped groove 131. The telescopic rod 22 is arranged vertically below the crossbeam 21, and the upper end of the telescopic rod 22 is arranged along the length direction of the crossbeam 22. The lower end of the telescopic rod 22 is connected with a connecting seat 221 of inverted U-shaped structure. The center of the horizontal part of the connecting seat 221 is connected with the lower end of the telescopic rod 22. The installation plate 23 is arranged at the lower end of the connecting seat 221, and the lower ends of the two side arms of the connecting seat 221 are respectively connected with the two sides of the middle part of the installation plate 23. The installation cylinder 24 is arranged vertically below one end of the installation plate 23. The lower end of the installation cylinder 24 is circularly arrayed with square holes 243. The installation cylinder 24 is internally provided with a supporting rod 242. The upper end of the supporting rod 242 is connected with the output end of a first air cylinder 241. The first air cylinder 241 is installed at one end of the installation plate 23 and above the installation cylinder 24. Figures 3-4 As shown, the material taking piece 25 is respectively arranged in the square hole 243. The material taking piece 25 includes a square rod 251. The cross-sectional dimension of the square rod 251 matches the inner wall dimension of the square hole 243. The square rod 251 is arranged in the square hole 243. The end of the square rod 251 extending into the installation cylinder 24 is provided with an inner plate 252. The other end is provided with an outer plate 253. A spring 254 is arranged on the square rod 251. One end of the spring 254 abuts against one side of the inner plate 252. The other end of the spring 254 abuts against the inner wall of the installation cylinder 24. When the material taking piece 25 is not subjected to external force, the outer plate 253 is in contact with the outer wall of the installation cylinder 24. Figure 4 As shown, the bottom of the arc-shaped groove 131 is concentrically provided with a stepped groove 132 for avoiding the supporting rod 242 when the supporting rod 242 moves downward. The circumferential side of the stepped groove 132 is circularly arrayed with guide grooves 133. When the installation cylinder 24 is above the arc-shaped groove 131, the guide grooves 133 are respectively below the square holes 243. The width of the guide grooves 133 matches the width of the outer plate 253. The guide grooves 133 are outwardly recessed. When the lower end of the supporting rod 242 moves vertically downward into the stepped groove 132, the supporting rod 242 pushes the inner plate 252 to move outward, so that the outer plate 253 is expanded outward along the guide groove 133, thereby tightly stretching the sealing ring 2 in the arc-shaped groove 131 to the outer wall of the distribution track of the outer plate 253. The design of the guide groove 133 not only can reduce the diameter dimension of the stepped groove 132 to avoid the sealing ring 2 from falling into the stepped groove 132, but also can keep the movement of the outer plate 253 stable, so that the sealing ring 2 is tightly sleeved to the outer wall of the outer plate 253. The pressing ring 26 is concentrically arranged on the outer circumference of the installation cylinder 24. When the outer plate 253 sleeves the sealing ring 2 to the outer wall of the outer plate 253, the diameter of the circle formed by the track of the outer wall of the outer plate 253 matches the inner wall diameter dimension of the pressing ring 26.

[0028] The specific use process is as follows:

[0029] The diaphragm 1 is placed sequentially on the first conveyor belt 11, and the sealing ring 2 is placed sequentially on the second conveyor belt 13, and they are conveyed synchronously. When the diaphragm 1 at the forefront of the conveying direction of the first conveyor belt 11 moves to the assembly table 12 and enters the receiving groove, the suction cup 121 is activated to fix the diaphragm 1. The first conveyor belt 11 is paused, and the telescopic rod 22 is activated to move along the length of the crossbeam 21 until the mounting cylinder 24 moves directly above the arc groove 131 and is concentric with the arc groove 131. The telescopic rod 22 is then moved vertically downward so that the mounting cylinder 24 enters the sealing ring 2 to be transferred. The first cylinder 241 is activated to move the support rod 242 vertically downward. When the lower end of the support rod 242 moves into the stepped groove 132, the outer wall of the support rod 242 pushes the inner plate 2 of each material picking component 25. 52 moves outward along its corresponding square hole 243, thereby causing the outer plate 253 to move along the corresponding guide groove 133, so that the inner wall of the same sealing ring 2 is tightly stretched to the outer wall of each outer plate 253. The telescopic rod 22 is activated again, causing the telescopic rod 22 to move vertically upward, thereby lifting the sealing ring 2 upward. Then, the telescopic rod 22 is moved along the length direction of the crossbeam 21 to the top of the receiving groove, and the telescopic rod 22 is moved vertically downward. When the lower end of the mounting cylinder 22 contacts the top surface of the diaphragm 1, the pressure ring 26 is activated, and the first cylinder 241 enters the return stroke upward, thereby causing the inner plate 252 to lose the thrust of the support rod 242, thereby causing the outer plate 253 to move towards the outer wall of the mounting cylinder 24, thereby causing the sealing ring 2 to detach from the outer plate 253, and under the action of the pressure ring 26, the sealing ring 2 is pressed onto the diaphragm 1, thereby realizing the installation of the sealing ring.

[0030] Preferably, the lower end of the support rod 242 has a tapered structure with the small end facing downwards, so as to avoid the lower end of the support rod 242 getting stuck with the upper end of the inner plate 252 when pushing the material take-up part 25 outwards.

[0031] Preferably, the inner wall of the inner plate 252 has an arc-shaped structure, and its curvature is consistent with the outer circumference curvature of the support rod 242, so that when the support rod 242 pushes the inner plate 252 to move outward, the inner wall of the inner plate 252 and the outer wall of the support rod 242 are stably attached.

[0032] Specifically, such as Figure 3 As shown, the other end of the mounting plate 23 is provided with a second cylinder 231. The output end of the second cylinder 231 passes vertically downward through the mounting plate 23 and is provided with a T-shaped seat 232. The T-shaped seat 232 is set horizontally so that the horizontal part of the T-shaped seat 232 faces the middle of the outer wall of the lower pressure ring 26, thereby controlling the downward or upward movement of the lower pressure ring 26 by the extension and retraction of the second cylinder 231.

[0033] The above merely describes preferred embodiments of the present application and is not intended to represent the only or the best embodiments. Those skilled in the art should understand that various changes or equivalent replacements made to the present application without departing from the scope of the present application are all within the scope of the present application.
