Description

Technical Field

[0001] The invention relates to the technical field of headphone shell glue wiping, and in particular to a device for wiping glue overflow after bonding a headphone shell. Background Art

[0002] After the earphone shell is bonded, it is very necessary to wipe the glue. First, from the perspective of appearance, wiping the glue can ensure that the surface of the earphone shell is neat and smooth, and improve the overall aesthetics of the product. Secondly, if the excess glue is not cleaned, it may affect the assembly accuracy of the earphone, resulting in the inability to fit the parts tightly. The patent cited in China Publication No. CN113798224B discloses an automatic glue wiping machine for earphones, including: a machine platform, a cloth strip conveying mechanism, an earphone clamping mechanism, and a pressure wheel slide rail mechanism. The cloth strip conveying mechanism is used to convey the cloth strip, and the cloth strip is used to wipe the glue overflowed from the connection seam of the earphone shell. The earphone clamping mechanism is used to fix the earphone and completely fix the earphone. The pressure wheel slide rail mechanism is used to press the cloth strip against the connection seam of the earphone shell and keep a suitable angle and distance between the cloth strip and the connection seam to ensure that there is a suitable friction between the cloth strip and each point at the connection seam. The glue overflowing on the earphone shell dries very quickly, so it is difficult to clean it directly during the cleaning process. In addition, the glue that is cleaned off is sticky, so the glue adheres and aggregates, affecting the subsequent cleaning efficiency. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a device for wiping glue overflow after bonding of an earphone shell, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for erasing glue overflow after bonding an earphone shell, comprising a base, the outer wall of the base is fixedly connected to a fan, the outer wall of the fan is rotatably connected to a first rotating roller, the outer wall of the first rotating roller is sleeved with a conveyor belt, and the outer wall of the base is fixedly connected to a bumping mechanism; The jolting mechanism comprises: A telescopic machine, the outer wall of which is fixedly connected to the outer wall of the base; A telescopic rod, wherein the telescopic rod is movably connected to the top of the telescopic machine. When the telescopic rod descends, it drives the right side of the conveyor belt to descend, and then rises and resets after an interval of thirty seconds. When the right side of the conveyor belt descends, the inclined state of the conveyor belt at this time guides the shell to roll on the conveyor belt, and then rolls toward the right side of the conveyor belt. The surface of the conveyor belt is provided with a plurality of protrusions, which can clean the overflow glue on the shell during the friction process. By utilizing the right side of the conveyor belt to descend and the continuous rotation of the conveyor belt, the shell can be guided to continuously move on the conveyor belt, thereby ensuring the continuous friction between the conveyor belt and the shell, and cleaning the overflow glue on the shell. A bearing, wherein the outer wall of the bearing is fixedly connected to the top of the telescopic rod, and the outer wall of the bearing is rotatably connected to a second rotating roller.

[0005] Preferably, the second rotating roller is located on the inner wall of the conveyor belt, and the telescopic rod drives the second rotating roller to rise and fall through the bearing during the extension and retraction process. The change in the rising speed of the conveyor belt causes the shell to rise rapidly, and the conveyor belt stops when it rises to a fixed position. At this time, the shell jumps up under its own inertia and then falls down to collide with the surface of the conveyor belt. During the collision, it rubs against the conveyor belt, causing the overflowed glue on the shell to fall off. The inertia is used to increase the friction between the shell and the conveyor belt, thereby ensuring the cleaning of the overflowed glue and improving the cleaning efficiency.

[0006] Preferably, the fan is internally rotatably connected with a differential, and the differential is fixedly connected to the outer wall of the first rotating roller.

[0007] Preferably, a transverse tube is fixedly connected to the outer wall of the fan, and the outer wall of the transverse tube is fixedly connected to the outer wall of the base.

[0008] Preferably, a plurality of first airflow tubes are fixedly connected to the outer wall of the transverse tube, and the plurality of first airflow tubes are located on one side of the conveyor belt.

[0009] Preferably, the outer wall of the horizontal tube is fixedly connected with a second airflow tube, and the second airflow tube is located on the other side of the conveyor belt. The second airflow tube and the first airflow tube are arranged in a staggered position. When the first airflow tube blows out airflow, it will drive the shell on the conveyor belt to move. The airflow will drive the shell on the conveyor belt to move, and clean the overflowed glue on the shell. The impact of the airflow is used to clean the overflowed glue adhering to the shell, and the airflow will also drive the shell to move, so that the shell rubs against the conveyor belt many times.

[0010] Preferably, the outer wall of the conveyor belt is fixedly connected with a processing mechanism, and the processing mechanism comprises a slide groove, and the slide groove is opened on the outer wall of the conveyor belt.

[0011] Preferably, the inner wall of the slide groove is slidably connected with a slider, and the inner wall of each slide groove is provided with three sliders.

[0012] Preferably, the top of the slider is fixedly connected to a windward plate, and the top of the windward plate is fixedly connected to a cleaning ring. The telescopic machine drives the conveyor belt to swing up and down. At this time, the shell is located on the conveyor belt and circulates. When the shell moves through the connecting line, the shell will scrape the connecting line many times, so that the connecting line cleans the overflow glue on the shell, thereby improving the cleaning efficiency of the overflow glue of the shell. The first airflow pipe and the second airflow pipe are arranged at an staggered position, so when the airflow blows to the windward plate, it will drive the movement of the slider in the slide groove, and when the windward plate moves, it will drive the cleaning ring to move, and then clean the glue on the surface of the connecting line to avoid the accumulation of residual overflow glue.

[0013] Preferably, the outer wall of the conveyor belt is fixedly connected to a connecting wire at the position of the slide groove, and the connecting wire is inserted in the cleaning ring. The connecting wire is located at the same height as the shell, so when the conveyor belt rotates and drives the shell to move, the shell contacts the connecting wire, the connecting wire will scrape the shell, and then clean the overflowed glue on the shell, and the connecting wire will rub through the shell. When the connecting wire passes through the overflowed glue, the two are stuck to each other and then clean the overflowed glue, thereby improving the cleaning efficiency of the overflowed glue.

[0014] The present invention provides a device for erasing glue overflow after bonding of earphone shells, which has the following beneficial effects: 1. The device for wiping glue overflow after the earphone shell is bonded will drive the right side of the conveyor belt to descend when the telescopic rod descends, and then rises and resets after an interval of thirty seconds. When the right side of the conveyor belt descends, the inclined state of the conveyor belt at this time will guide the shell to roll on the conveyor belt, and then roll toward the right side of the conveyor belt. The surface of the conveyor belt is provided with a plurality of protrusions, which will clean the overflow glue on the shell during the friction process. The right side of the conveyor belt is descended and the continuous rotation of the conveyor belt is used to guide the continuous movement of the shell on the conveyor belt, thereby ensuring the continuous friction between the conveyor belt and the shell and cleaning the overflow glue on the shell.

[0015] 2. The device for wiping glue overflow after bonding of the earphone shell can rapidly rise the shell by changing the rising speed of the conveyor belt. The conveyor belt stops when it rises to a fixed position. At this time, the shell jumps up under its own inertia and then falls down to collide with the surface of the conveyor belt. During the collision, it rubs against the conveyor belt to make the overflow glue on the shell fall off. The inertia is used to increase the friction between the shell and the conveyor belt, thereby ensuring the cleaning of the overflow glue and improving the cleaning efficiency.

[0016] 3. The device for wiping glue overflow after the earphone shell is bonded has the second airflow tube and the first airflow tube arranged in a staggered position. When the first airflow tube blows out airflow, it will drive the shell on the conveyor belt to move. The airflow will drive the shell to move on the conveyor belt to clean the overflow glue on the shell. The impact of the airflow is used to clean the overflow glue adhering to the shell. The airflow will also drive the shell to move, so that the shell will rub against the conveyor belt many times.

[0017] 4. The device for wiping glue overflow after the earphone shell is bonded is located at the same height as the shell through the connecting line. Therefore, when the conveyor belt rotates to drive the shell to move, the shell contacts the connecting line, the connecting line will scrape the shell, and then clean the overflow glue on the shell. The connecting line will rub through the shell. When the connecting line passes through the overflow glue, the two are stuck to each other and then clean the overflow glue, which improves the cleaning efficiency of the overflow glue.

[0018] 5. The device for wiping glue overflow after the earphone shell is bonded drives the conveyor belt to swing up and down through the telescopic machine. At this time, the shell is located on the conveyor belt and circulates. When the shell moves through the connecting line, the shell will scrape the connecting line many times, so that the connecting line cleans the overflow glue on the shell, thereby improving the cleaning efficiency of the shell overflow glue. The first airflow pipe and the second airflow pipe are arranged at staggered positions, so when the airflow blows to the windward plate, it will drive the movement of the slider in the slide groove. When the windward plate moves, it will drive the cleaning ring to move, and then clean the glue on the surface of the connecting line to avoid the accumulation of residual overflow glue.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] For example, see Figure 1-6 The present invention provides a technical solution: a device for erasing glue overflow after bonding of an earphone shell, comprising a base 1, a fan 54 is fixedly connected to the outer wall of the base 1, a first rotating roller 2 is rotatably connected to the outer wall of the fan 54, a conveyor belt 3 is sleeved on the outer wall of the first rotating roller 2, and a bumping mechanism 5 is fixedly connected to the outer wall of the base 1; The jolting mechanism 5 comprises: The telescopic machine 51, the outer wall of the telescopic machine 51 is fixedly connected to the outer wall of the base 1, and the telescopic machine 51 drives the conveyor belt 3 to swing up and down. At this time, the shell is located on the conveyor belt 3 and circulates. When the shell moves through the connecting line 65, the shell will scrape the connecting line 65 many times, so that the connecting line 65 cleans the overflow glue on the shell, which improves the cleaning efficiency of the overflow glue on the shell. The first airflow pipe 56 and the second airflow pipe 57 are arranged at staggered positions, so when the airflow blows to the windward plate 63, it will drive the slider 62 located in the slide groove 61 to move. When the windward plate 63 moves, it will drive the cleaning ring 64 to move, and then clean the glue on the surface of the connecting line 65 to avoid the accumulation of residual overflow glue; The telescopic rod 52 is movably connected to the top of the telescopic machine 51. When the telescopic rod 52 descends, it will drive the right side of the conveyor belt 3 to descend, and then rise and reset after an interval of thirty seconds. When the right side of the conveyor belt 3 descends, the inclined state of the conveyor belt 3 at this time will guide the shell to roll on the conveyor belt 3, and then roll toward the right side of the conveyor belt 3. The surface of the conveyor belt 3 is provided with a plurality of protrusions, which will clean the overflow glue on the shell during the friction process. The right side of the conveyor belt 3 is descended and the conveyor belt 3 is continuously rotated, so that the shell can be guided to continuously move on the conveyor belt 3, ensuring the continuous friction between the conveyor belt 3 and the shell, and cleaning the overflow glue on the shell. The bearing 53 has an outer wall fixedly connected to the top of the telescopic rod 52 , and the outer wall of the bearing 53 is rotatably connected to the second rotating roller 4 .

[0024] The second rotating roller 4 is located on the inner wall of the conveyor belt 3 , and the telescopic rod 52 drives the second rotating roller 4 to rise and fall through the bearing 53 during the telescopic process.

[0025] The fan 54 is internally rotatably connected with a differential, and the differential is fixedly connected to the outer wall of the first rotating roller 2 .

[0026] The outer wall of the fan 54 is fixedly connected with a transverse pipe 55 , and the outer wall of the transverse pipe 55 is fixedly connected to the outer wall of the base 1 .

[0027] A plurality of first airflow pipes 56 are fixedly connected to the outer wall of the transverse pipe 55 , and the plurality of first airflow pipes 56 are located on one side of the conveyor belt 3 .

[0028] The outer wall of the transverse tube 55 is fixedly connected with a second airflow tube 57 , and the second airflow tube 57 is located on the other side of the conveyor belt 3 .

[0029] When in use, the earphone shell is placed on the conveyor belt 3, and the fan blades inside the fan 54 rotate to fan the airflow, so the rotation of the fan blades will drive the rotation of the differential, and the differential transmits the rotation force to the first rotating roller 2. Therefore, when the fan 54 drives the fan blades to rotate quickly to fan the airflow, it can also drive the first rotating roller 2 to rotate slowly. When the first rotating roller 2 rotates, it will drive the conveyor belt 3 to rotate, so it will transport the earphone shell on it; Optionally, baffles may be provided on both sides of the conveyor belt 3 to prevent the shell from falling; Combined with Figure 1 As shown, the conveyor belt 3 drives the shell to move toward the left side during rotation, and then the telescopic machine 51 is powered on to drive the telescopic rod 52 to telescope. When the telescopic rod 52 descends, it drives the right side of the conveyor belt 3 to descend, and then rises and resets after an interval of thirty seconds. When the right side of the conveyor belt 3 descends, the inclined state of the conveyor belt 3 at this time will guide the shell to roll on the conveyor belt 3, and then roll toward the right side of the conveyor belt 3. The surface of the conveyor belt 3 is provided with a plurality of protrusions, which will clean the overflow glue on the shell during the friction process; Combined with Figure 5 As shown, a control chip is provided inside the telescopic machine 51, which drives the conveyor belt 3 to rise faster, so the shell on the conveyor belt 3 will rise quickly, and then the conveyor belt 3 will stop when it rises to a fixed position. At this time, the shell will jump up under its own inertia and then fall down to collide with the surface of the conveyor belt 3. During the collision, it will rub against the conveyor belt 3, causing the overflow glue on the shell to fall off; Combined with Figure 6 As shown, the fan 54 blows out air through the first airflow pipe 56 and the second airflow pipe 57 on the transverse pipe 55, and the second airflow pipe 57 and the first airflow pipe 56 are arranged in a staggered position. Then, when the first airflow pipe 56 blows out air, it drives the shell on the conveyor belt 3 to move, and then the conveyor belt 3 drives the shell to move to the position of the first airflow pipe 56 or the second airflow pipe 57, and then drives the shell to move on the conveyor belt 3 to clean the overflow glue on the shell. Optionally, in the case of installing a baffle on the conveyor belt 3 as mentioned above, the heights of the first airflow tube 56 and the second airflow tube 57 can be increased, and then the first airflow tube 56 and the second airflow tube 57 can be tilted.

[0030] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The outer wall of the conveyor belt 3 is fixedly connected with a processing mechanism 6 . The processing mechanism 6 includes a slide groove 61 . The slide groove 61 is opened on the outer wall of the conveyor belt 3 .

[0031] The inner wall of the slide groove 61 is slidably connected with a slider 62 , and three sliders 62 are disposed on the inner wall of each slide groove 61 .

[0032] The top of the sliding block 62 is fixedly connected with a windward plate 63 , and the top of the windward plate 63 is fixedly connected with a cleaning ring 64 .

[0033] A connection line 65 is fixedly connected to the outer wall of the conveyor belt 3 at the position of the slide groove 61 , and the connection line 65 is inserted into the cleaning ring 64 .

[0034] When in use, the cleaning ring 64 is set to lift the connecting wire 65, and then the connecting wire 65 is located at the same height as the shell, so when the conveyor belt 3 rotates to drive the shell to move, the shell contacts the connecting wire 65, and the connecting wire 65 scrapes the shell, and then cleans the overflow glue on the shell; Combined with Figure 7 and 3 As shown, the telescopic machine 51 drives the conveyor belt 3 to swing up and down, and at this time the shell is located on the conveyor belt 3 and circulates. When the shell moves through the connecting line 65, the shell will scrape the connecting line 65 many times, so that the connecting line 65 cleans the overflow glue on the shell; Combined with Figure 8 and 6 As shown, the first airflow pipe 56 and the second airflow pipe 57 are arranged at staggered positions, so when the airflow blows to the windward plate 63, it will drive the slider 62 located in the slide groove 61 to move, and when the windward plate 63 moves, it will drive the cleaning ring 64 to move, and then clean the glue on the surface of the connecting line 65; In the present application, when the conveyor belt 3 rotates and drives the shell to move toward the left side, because the telescopic machine 51 drives the conveyor belt 3 to descend, the shell can be guided to move toward the right side again, so the overflow glue on the shell is cleaned several times, and the shell on the conveyor belt 3 is removed after cleaning.
