Description

Technical Field

[0001] The utility model relates to the technical field of earphone production and processing, in particular to a glue dispensing device for earphone production and processing. Background Art

[0002] Headphones receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. This helps block out ambient noise, making them very helpful for people using them in noisy environments such as recording studios, bars, while traveling, and during exercise. During the production of headphones, the soldered wire ends inside the headphone speakers need to be sealed with insulating glue to cover the soldering points in order to protect the ears.

[0040] As a technical optimization solution of the present invention, a controller is installed at the rear end of the bracket 14.

[0041] In this embodiment, the controller is electrically connected to the electric push rod 15, the first conveyor 12, the second conveyor 13, the first electric guide rail 3, the second electric slide rail 19 and the motor 7, which makes the operation more convenient.

[0042] Working Principle: When in use, the earphone carrier plate to be glued is first placed on the upper end of the first conveyor 12 for conveying. When the non-contact sensor 21 senses the earphone carrier plate, it transmits a signal to the controller, which stops the first conveyor 12.

[0043] At the same time, the first electric guide rail 3 is started by the controller to drive the first slider 4 to move to the left, so that the two clamping plates 11 are located on both sides of the earphone carrying plate at the upper end of the first conveyor 12. At this time, the driving gear 8 rotates, and when the gear 8 rotates, the two racks 9 are driven to move in the opposite direction. When the two racks 9 move in the opposite direction, the supporting plate 10 and the clamping plate 11 connected thereto are driven to move relative to each other to clamp the earphone carrying plate. Then, the first electric guide rail 3 is started again to drive the first slider 4 to move to the right, and the clamped earphone carrying plate is moved to the middle of the workbench 2, and the two clamping plates 11 are reset.

[0044] Then, the electric push rod 15 can drive the horizontal plate 16 and the second electric slide 19 and the glue gun 18 to move up and down, so that the glue gun 18 can be brought into contact with the earphone. The second electric slide 19 can drive the second slider 17 to move forward and backward, so that glue can be dispensed on multiple earphones.

[0045] After the glue is dispensed by the glue gun 18, the electric push rod 15 stops working and transmits a signal to the controller, which starts the first conveyor 12 to continue working, and moves the earphone carrier plate to a position close to the workbench 2 again. When the non-contact sensor 21 senses the earphone carrier plate, it transmits a signal to the controller, which stops the first conveyor 12 through the controller, and at the same time starts the first electric guide rail 3 again through the controller. The first electric guide rail 3 drives the first slider 4 to move to the left, so that the two splints 11 are located on both sides of the earphone carrier plate, and drives the gear 8 to rotate again. When the gear 8 rotates, it drives the two racks 9 to move in the opposite direction. When the two racks 9 move in the opposite direction, The support plate 10 and the clamping plate 11 connected thereto move relative to each other to clamp the earphone carrier plate. At this time, the earphone carrier plate located at the upper end of the first conveyor 12 is clamped, and the earphone carrier plate after gluing is clamped together. Then the first electric guide rail 3 is started, and the first electric guide rail 3 drives the first slider 4 to move to the right, so that the earphone carrier plate located at the upper end of the first conveyor 12 can be moved to the middle of the workbench 2, and the earphone carrier plate after gluing will move to the upper end of the second conveyor 13. The earphone carrier plate after gluing is transported by the second conveyor 13, so that the earphone carrier plate is automatically clamped and automatically loaded and unloaded at the same time, which is convenient to use.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
