[0026] In use, the bottom end of the glue suction pipe 26 is inserted into the glue container, the electric push rod 21 drives the screw rod 24 to move, and then drives the piston rod 23 to move, so that the glue in the piston cylinder 22 is injected into the hose 19, the output end of the electric push rod 21 is connected with the screw rod 24, the electric push rod 21 pulls the screw rod 24 and the piston rod 23 to reset, so that the glue in the glue container is sucked through the glue suction pipe 26, so that the glue is conveyed, the one-way valve is used to make the glue in the glue suction pipe 26 and the hose 19 flow in one direction, during use, the staff can adjust the position of the limiting seat 25 on the screw rod 24, so as to adjust the glue output, so as to assist the electric push rod 21, improve the accuracy of the glue output, and rely on the screw to fix the fixed seat 52 and the fastening seat 51, so as to fix the end of the buffer rod 41 by clamping, so as to fix the end of the electric push rod 21 and the buffer rod 41.

[0027] Further, as shown in Figures 3-4 The top of the support is fixedly connected with a guide sleeve 31; the piston rod 23 is located in the middle of the guide sleeve 31; a plurality of sliding grooves are formed in the inner side wall of the guide sleeve 31; a guide block 32 is fixedly connected to one end of the piston rod 23 close to the screw rod 24; the guide block 32 is in sliding connection with the sliding grooves; in use, the guide block 32 slides in the sliding grooves in the inside of the guide sleeve 31, so that the movement of the guide block 32 can be guided and positioned, and the movement of the screw rod 24 is supported, and the piston rod 23 cannot rotate, so that the position of the limiting seat 25 on the screw rod 24 can be adjusted conveniently.

[0028] Further, as shown in Figures 3-4 The middle of the screw rod 24 is provided with a sliding hole; the buffer rod 41 is in sliding connection with the sliding hole; the buffer rod 41 and the screw rod 24 are fixedly connected with a spring; a plurality of embedded grooves 43 are formed in the side surface of the sliding hole; the embedded grooves 43 are provided with rubber balls 42; the surface of the buffer rod 41 is provided with a clamping groove at a position corresponding to the rubber ball 42; in long-term use, the pushing speed of the electric push rod 21 is not uniform, so that the glue output speed is too fast, the rubber ball 42 is deformed by being extruded, the rubber ball 42 is separated from the clamping groove, the buffer rod 41 slides in the sliding hole, the spring is deformed, and then the screw rod 24 and the piston rod 23 are driven to move by the spring, so that the uniformity of the glue output is improved, and the sudden fast glue output is reduced.

[0029] Further, as shown in Figure 3As shown, the guide sleeve 31 is fixed with an oil bag ring 63 on the side away from the piston cylinder 22; the hose 19 is fixed with an elastic bag 62; the piston cylinder 22 is fixed with a tank 61 on the side close to the hose 19; the elastic bag 62 is located inside the tank 61; the hose 19 penetrates through and is fixed with the tank 61; the oil bag ring 63 and the tank 61 are fixed with an oil pipe therebetween; in use, when the limiting seat 25 contacts with the guide sleeve 31, the oil bag ring 63 is extruded, the liquid in the oil bag ring 63 is injected into the tank 61 through the oil pipe, thus the elastic bag 62 is extruded, so that the glue in the elastic bag 62 is extruded out, when the piston rod 23 resets to suck the glue, the elastic bag 62 is elastically restored, thus a small amount of glue in the glue applying pipe 18 is sucked back through the hose 19, thus the glue dripping from the pipe opening of the glue applying pipe 18 is reduced.

[0030] Further, as shown in the figure, Figure 4 the side of the guide block 32 is rotatably connected with a plurality of pulleys 7; in use, the pulleys 7 are arranged, thus the friction of the guide block 32 sliding in the guide sleeve 31 is reduced, thus the guide block 32 is facilitated to move, and the sliding abrasion of the guide block and the guide sleeve 31 is reduced.

[0031] In use, the earphone is placed on the top of the turntable 12, and the top of the prior art turntable 12 is provided with a corresponding earphone fixing jig. The turntable 12 is controlled to rotate by a servo motor in the fixed table body. The horizontal linear slide and the vertical linear slide are used to control the movement of the glue applying pipe 18. In use, the fan 15 is started to extract air in the cover body 13, so that a negative pressure area is formed below the exhaust cylinder 14. The extracted air is then discharged through the exhaust pipe 17. The end of the exhaust pipe 17 is connected to the outside or connected to an air treatment device. The harmful gas generated by the evaporation of the glue can be discharged, thereby reducing the inhalation of harmful gas by the workers, protecting the health of the workers, and reducing the odor in the working area. The bottom end of the glue suction pipe 26 is inserted into the glue container. The electric push rod 21 pushes the screw rod 24 to move, and then pushes the piston rod 23 to move, so that the glue in the piston cylinder 22 is injected into the hose 19. The output end of the electric push rod 21 is connected to the screw rod 24. The electric push rod 21 pulls the screw rod 24 and the piston rod 23 to reset. The glue in the glue container is extracted through the glue suction pipe 26. The glue is conveyed. The one-way valve is used to make the glue in the glue suction pipe 26 and the hose 19 flow in one direction. During use, the worker can adjust the position of the limiting seat 25 on the screw rod 24, so as to adjust the glue output, thereby assisting the electric push rod 21 and improving the accuracy of the glue output. In use, the guide block 32 slides in the sliding groove in the guide sleeve 31, so as to guide and position the movement of the guide block 32, thereby supporting the movement of the screw rod 24 and preventing the piston rod 23 from rotating. Therefore, the position of the limiting seat 25 on the screw rod 24 can be adjusted conveniently. In long-term use, the pushing speed of the electric push rod 21 may be uneven, which may cause the glue output to be too fast. When the glue output is too fast, the rubber ball 42 is deformed and separated from the clamping groove, so that the buffer rod 41 slides in the sliding hole, and the spring is deformed. Then the screw rod 24 and the piston rod 23 are pushed to move by the spring, so as to improve the uniformity of the glue output and reduce the sudden increase of the glue output. The fixing seat 52 and the fastening seat 51 are fixed by screws, so as to fix the end of the buffer rod 41 by clamping, thereby fixing the ends of the electric push rod 21 and the buffer rod 41. When the limiting seat 25 contacts with the guide sleeve 31, the oil bladder ring 63 is extruded, and the liquid in the oil bladder ring 63 is injected into the tank 61 through the oil pipe, so that the elastic bladder 62 is extruded to extrude the glue in the elastic bladder 62. When the piston rod 23 is reset to suck the glue, the elastic bladder 62 is elastically restored, so that a small amount of glue in the glue applying pipe 18 is sucked back through the hose 19, thereby reducing the dripping of the glue from the pipe opening of the glue applying pipe 18.
