Description

Technical Field

[0001] The utility model relates to the technical field of earphone production, in particular to an accurate glue coating device for earphone production. Background Technique

[0002] An earphone is a personal audio device used to transmit audio signals to the user's ears and usually consists of two earphone units and a connecting wire. Earphones can be connected to an audio source in a wired or wireless manner and are used for listening to music, answering calls, watching videos, etc. In the production process of earphones, the glue coating device is an important technological step. The assembly of earphones usually involves many small parts and components, such as speaker units, wires, connectors, etc. The glue coating device is used to fix these parts to ensure that they do not loosen or fall off during the use of the earphones.

[0003] In the traditional earphone production process, the earphone shell to be coated with glue is placed inside the earphone slot plate. These slot plates are made according to the shape and size of the earphone shell to ensure that each shell can be stably fixed in the correct position. Once the earphone shell is placed, the operator turns the bolt to drive the clamping plate to move and fix it. Then, the operator will hold a roller brush and move it along the upper surface of the earphone shell. During the movement, the roller brush will evenly apply an appropriate amount of glue to the designated area of the earphone shell. However, this traditional method does not consider the problem that it is rather troublesome to fix by pushing the clamping plate through bolts. For this reason, an accurate glue coating device for earphone production is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an accurate glue coating device for earphone production, aiming to improve the problem that it is rather troublesome to fix by pushing the clamping plate through bolts in the prior art.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a precise glue coating device for earphone production, including a base 1, on the upper surface of the base 1 is fixedly connected with a workbench 2, inside the workbench 2 is fixedly connected with a fixed column 3, on the side wall of the fixed column 3 is rotatably connected with a gear 4, inside the workbench 2 is fixedly connected with a sliding frame 5, on the side wall of the sliding frame 5 is slidably connected with a sliding ring 6, on the side wall of one sliding ring 6 is fixedly connected with a fixed block 7, on the side wall of the workbench 2 is fixedly connected with a fixed frame 8, inside the fixed frame 8 is fixedly connected with a first hydraulic rod 9, the output end of the first hydraulic rod 9 is fixedly connected to the side wall of the fixed block 7, on the side wall of the sliding ring 6 is fixedly connected with a rack 10, the rack 10 is engaged with the gear 4, inside the workbench 2 is provided with a limiting component, the limiting component is used to support the rack 10, on the upper surface of the rack 10 is fixedly connected with a clamping plate 11, the side wall of the clamping plate 11 is slidably connected inside the workbench 2, the limiting component includes a limiting frame 12, the side wall of the limiting frame 12 is fixedly connected inside the workbench 2, the side wall of the rack 10 is slidably connected to the side wall of the limiting frame 12;

[0032] During the process of earphone glue coating operation, we first need to ensure that the earphone housing is placed inside the earphone slot board. The earphone slot board is an existing technology that can be checked, and its function is to fix the earphone shell. Place the side of the earphone housing that needs to be coated with glue facing up and place it inside the slot board. After completing this step, next, place the slot board with the earphone housing on the surface of the workbench 2, and then start the first hydraulic rod 9 to pull the fixed block 7 to move along a predetermined trajectory. As the fixed block 7 moves, it will drive the connected sliding ring 6 to slide on the sliding frame 5. The movement of the sliding ring 6 will synchronously cause the rack 10 on one side to displace. Since the rack 10 is engaged with the gear 4, when the rack 10 on one side moves, it will, through the transmission of the gear 4, cause the rack 10 on the other side to move accordingly, ultimately achieving the movement of the clamping plate 11 towards the middle inside the workbench 2, thus ensuring the stability and accuracy of the earphone slot board during the glue coating process and completing the precise fixation of the earphone slot board.

[0033] Refer to Figure 4, a vertical frame 13 is fixedly connected to the upper surface of the base 1, a top plate 14 is fixedly connected to the upper surface of the vertical frame 13, a glue box 15 is arranged on the upper surface of the top plate 14, a stirring shaft 16 is rotatably connected inside the glue box 15, one end of the stirring shaft 16 penetrates through the side wall of the glue box 15 and is fixedly connected to a driven wheel 17, an installation table 18 is fixedly connected to the side wall of the glue box 15, a motor 19 is fixedly connected to the side wall of the installation table 18, a driving wheel 20 is fixedly connected to the output end of the motor 19, the driving wheel 20 is engaged with the driven wheel 17, a pump body 21 is fixedly connected inside the top plate 14, a feeding pipe 22 is fixedly connected to the input end of the pump body 21, one end of the feeding pipe 22 is arranged inside the glue box 15, a discharging pipe 23 is fixedly connected to the output end of the pump body 21, one end of the discharging pipe 23 is fixedly connected to a temporary storage bin 24, a glue plate 25 is arranged at the bottom of the temporary storage bin 24, a second hydraulic rod 26 is fixedly connected inside the top plate 14, and the output end of the second hydraulic rod 26 is fixedly connected to the side wall of the temporary storage bin 24.

[0034] After completing the fixing work of the earphone slot plate, then start the pump body 21. The function of this pump body 21 is to draw out the paint in the glue box 15 through the feeding pipe 22, and then transport the paint to the inside of the temporary storage bin 24 through the discharging pipe 23. The temporary storage bin 24 is a place for temporarily storing the paint, and it can temporarily store the paint until the next use. The paint in the temporary storage bin 24 is absorbed by the glue plate 25. In order to ensure that the glue plate 25 can be closely attached to the glue application surface of the earphone placed inside the earphone slot plate, it is necessary to start the second hydraulic rod 26. The function of the second hydraulic rod 26 is to drive the temporary storage bin 24 to move downward, so that the glue plate 25 can be in close contact with the glue application surface of the earphone inside the earphone slot plate, thereby achieving the effect of uniform glue application. When it is found that the paint in the glue box 15 has caked due to long-term placement, start the motor 19. The start of the motor 19 will drive the driving wheel 20 to rotate, and the rotation of the driving wheel 20 will further drive the driven wheel 17 to rotate, so that the stirring shaft 16 rotates inside the glue box 15. The rotation of the stirring shaft 16 can effectively stir the paint inside the glue box 15, break the caking in the paint, and restore it to a uniform state, so as to ensure the quality of the paint and the effect of glue application.

[0035] Working principle: When using this equipment for glue application of earphones, first place the earphone shell to be glued inside the earphone slot plate and place the side to be glued facing up. After placement, place the earphone slot plate on the top of the workbench 2, and then start the first hydraulic rod 9 to pull the fixed block 7 forward, thereby driving the connected sliding ring 6 to slide on the sliding frame 5 and synchronously driving the rack 10 on this side to move. Under the action of the engagement between the rack 10 and the gear 4, when one side of the rack 10 moves, it will drive the rack 10 on the other side to move relatively, so as to drive the clamping plate 11 to move inward inside the workbench 2 to fix the earphone slot plate;

[0036] After fixing the headphone slot board, by starting the pump body 21, the coating inside the glue tank 15 is pumped out through the feed pipe 22, conveyed into the temporary storage bin 24 through the discharge pipe 23, and finally absorbed by the rubber plate 25. Then, by starting the second hydraulic rod 26, it drives the temporary storage bin 24 to move downward, so that the rubber plate 25 is in contact with the headphone coating surface placed inside the headphone slot board. When the coating inside the glue tank 15 forms lumps after being placed for a long time, the motor 19 can be started to drive the driving wheel 20 to rotate, thereby driving the driven wheel 17 to rotate, and making the stirring shaft 16 rotate inside the glue tank 15 to stir the coating inside the glue tank 15.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
