The main raw materials of correction tape are similar to those of correction fluid, and the ingredients contained in correction fluid are methylcyclohexane. The internal structure of correction tape is composed of shell, gear, tape head, tape head cover, tape core and other components. The main components of the tape core are titanium dioxide, resin, polystyrene, self-adhesive, release paper, etc. From bottom to top, it can be divided into three layers of glue layer, paint layer and PET release film layer.

[0003] The correction tape gear assembly machine is the first step of correction tape assembly. The gear assembly machine is divided into four stations, namely large tooth station, spring station, inner disc station and feeding station.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0022] Please refer to Figures 1 to 8 A clamping wheel assembly device for external assembly of a correction tape, comprising a body 1 and a controller 11 arranged on the front side of the body 1, the body 1 is in the shape of "L", the front side of the vertical part of the body 1 is slidingly connected with a moving seat 14, and the inner and outer sides of the vertical part of the body 1 are jointly provided with a correction component 2; The correction part 2 comprises an electric guide rail 21 fixedly connected in the vertical part of the body 1 in a transverse linear array arrangement, and a drive motor 22 is arranged on the front and back of the moving seat 14, and the output end of the drive motor 22 is fixedly connected with a rotating rod 23, the first embedding slot 24 is arranged on the front and back of the rotating rod 23, the first magnetic block 25 is slidably connected in the first embedding slot 24, the first pressure spring 26 is fixedly connected between the first embedding slot 24 and the first magnetic block 25, the hollow slot 27 is arranged at the center of the electric guide rail 21, the gear ring 271 is fixedly connected in the hollow slot 27, the gear 17 is slidably connected on the front and back of the electric guide rail 21, and the rotating rod 23 penetrates the gear 17 after moving downward.

[0023] The first sliding groove 12 is arranged on the left and right sides of the front side of the vertical part of the body 1, the first sliding block 13 is slidably connected in the first sliding groove 12, the moving groove 15 is arranged on the front side of the vertical part of the body 1, the first sliding block 13 on the left and right sides is fixedly connected with the moving seat 14, the moving seat 14 is slidably connected in the moving groove 15 at the extension of the back side, the electric push rod 16 is arranged on the upper side of the vertical part of the body 1, and the extension of the moving seat 14 is fixedly connected with the electric push rod 16.

[0024] The gear ring 271 and the hollow slot 27 are both in the shape of "8", the gear 17 is embedded in the hollow slot 27 after moving downward, the teeth on the outer surface of the gear 17 and the teeth on the inner surface of the gear ring 271 are in meshing engagement, and the first magnetic block 25 is in extrusion contact with the inner side wall of the gear 17 after being inserted into the gear 17.

[0025] The electric guide rail 21 is provided with a locking assembly 28.

[0026] By adopting the above technical scheme, after the electric guide rail 21 delivers the two gears 17 to the inside of the same hollow groove 27, the electric push rod 16 pushes the part of the extension of the moving seat 14 into the inside of the guide groove, so that the moving seat 14 drives the driving motor 22 and the rotating rod 23 to move downward at the same time. At this time, the first sliding block 13 on the back side of the moving seat 14 will slide in the first sliding groove 12 on the surface of the machine body 1. When the rotating rod 23 is inserted into the inside of the gear 17, the first pressure spring 26 in the first embedded groove 24 pushes the first magnetic block 25, so that the first magnetic block 25 is in contact with the inner wall of the gear 17. At this time, the electric push rod 16 temporarily stops pushing the moving seat 14 downward. Because the first magnetic block 25 increases the friction between the rotating rod 23 and the gear 17, the driving motor 22 drives the rotating rod 23 to slowly rotate, which will drive the two gears 17 to rotate temporarily in the hollow groove 27. With the interlocking of the teeth of the gear 17 and the teeth of the tooth ring 271, the electric push rod 16 drives the rotating rod 23 to push the gear 17 downward again. Because the part of the rotating rod 23 provided with the first magnetic block 25 passes through the gear 17, the first magnetic block 25 in the inner cavity of the tooth ring 271 cooperates with the locking assembly 28 to release the locking of the gear 17, so that the two gears 17 descend due to their own weight and always keep the meshing state, but always set on the outside of the rotating rod 23. Finally, the machine body 1 is assembled. Because the two gears 17 can be adjusted by the rotation of the rotating rod 23 before assembly, and the assembly of the two gears 17 is ensured after complete meshing, the transmission efficiency of the two gears 17 after assembly is ensured, thereby reducing the transmission efficiency quality inspection steps of the gear 17 after assembly, and ensuring the assembly efficiency of the gear 17.

[0027] As shown in Figure 4 , Figure 5 , Figure 7 and Figure 8 , the locking assembly 28 includes a second embedded groove 281 opened on the front and rear sides of the inner wall of the hollow groove 27.

[0028] The inside of the second embedded groove 281 is slidably connected with a second magnetic block 282. The second embedded groove 281 and the second magnetic block 282 are fixedly connected with a second pressure spring 283. The side away from the second magnetic block 282 on the front and rear sides is fixedly connected with a striker 284. The side away from the second embedded groove 281 on the front and rear sides is fixedly connected with a pressure sensor 285. The striker 284 moves and is in extrusion contact with the surface of the pressure sensor 285. The first magnetic block 25 and the second magnetic block 282 on the front and rear sides repel each other in terms of magnetism.

[0029] By adopting the above technical scheme, when the first magnetic block 25 passes through the gear 17 and is in the inner cavity of the tooth ring 271, the second magnetic block 282 exposed from the inside of the second embedding groove 281 supports the gear 17 entering the inside of the tooth ring 271, and the first magnetic block 25 and the second magnetic block 282 repel each other and then move away from each other, so that the first magnetic block 25 is retracted into the inside of the first embedding groove 24 and presses the first pressure spring 26, and the second magnetic block 282 is retracted into the inside of the second embedding groove 281 and presses the second pressure spring 283. In the process that the second magnetic block 282 presses the second pressure spring 283, the second magnetic block 282 drives the striker 284 to move towards the position of the pressure sensor 285. When the striker 284 contacts the pressure sensor 285, the pressure sensor 285 transmits information to the controller 11, and the controller 11 controls the electric push rod 16 to quickly push the moving seat 14 downward. When the electric push rod 16 is stretched to the maximum stretching range, because the first magnetic block 25 and the second magnetic block 282 move away from each other, the first magnetic block 25 is exposed from the inside of the first embedding groove 24, and the gear 17 enters the inside of the workpiece smoothly under the guidance of the rotating rod 23 cooperating with the first magnetic block 25. Then the driving motor 22 drives the rotating rod 23 to rotate several turns, so that the two gears 17 mesh and rotate in the workpiece. Because the exposed second magnetic block 282 supports the two gears 17, the two gears 17 can mesh in the inside of the tooth ring 271. After the second magnetic block 282 releases the locking of the gear 17, the gear 17 is assembled under the limitation of the rotating rod 23, and the rotating rotating rod 23 can complete the transmission efficiency test of the two gears 17, so that the assembly efficiency of the gear 17 is further guaranteed.

[0030] As shown in Figure 4 , Figure 6 and Figure 7 , the inner and outer sides of the rotating rod 23 are jointly provided with a counterweight assembly 29, and the counterweight assembly 29 includes a second sliding groove 291 opened on the left and right sides of the rotating rod 23.

[0031] The inside of the second sliding groove 291 is slidably connected with a second sliding block 292, and the outer side of the rotating rod 23 is slidably sleeved with a counterweight sleeve 293, and the left and right second sliding blocks 292 are fixedly connected to the left and right sides inside the counterweight sleeve 293.

[0032] By adopting the above technical solution, before the counterweight sleeve 293 on the outside of the rotating rod 23 contacts the gear 17, the first magnetic block 25, pushed by the first pressure spring 26, squeezes the inner wall of the counterweight sleeve 293. Since the gear 17 is supported by the second magnetic block 282 after entering the gear ring 271, as the rotating rod 23 continues to move downwards, the first magnetic block 25 will pass through the counterweight sleeve 293. As the rotating rod 23 contacts the workpiece, the gear 17 on the outside of the rotating rod 23 will enter the workpiece for assembly. Subsequently, the counterweight sleeve 293 presses down on the gear 17. When the rotating rod 23 drives the gear 17 to rotate, the rotating rod 23 moves upwards. Because the counterweight sleeve 293 always presses down on the gear 17, the rotating rod 23 and the first magnetic block... 25 disengages from the inside of gear 17, causing the rotating rod 23 to move upward and drive the first magnetic block 25 back into the inside of the counterweight sleeve 293. Meanwhile, the second slider 292 inside the counterweight sleeve 293 slides inside the second groove 291 outside the rotating rod 23, allowing the rotating rod 23 to also drive the counterweight sleeve 293 to move upward. Since the counterweight sleeve 293 always presses against the gear 17 during the assembly process of gear 17 and workpiece, it can effectively prevent the two gears 17 from misaligning or deviating during the transmission efficiency test. On the one hand, it ensures the transmission efficiency test efficiency of gear 17, and on the other hand, it prevents gear 17 from disengaging from the inside of workpiece, thus ensuring the assembly efficiency of gear 17 again.

[0033] like Figures 6 to 8 As shown, the inner and outer sides of the rotating rod 23 are provided with a lubrication component 3, which includes a pressing rod 31 that is slidably connected to the upper side of the second slide groove 291.

[0034] A piston disc 32 is fixedly connected to the top of the extrusion rod 31. Piston chambers 33 are opened on both the left and right sides inside the rotating rod 23. The piston disc 32 is slidably connected inside the piston chamber 33. A conveying chamber 34 is opened at the center of the rotating rod 23. The conveying chamber 34 is connected to the piston chamber 33. A storage chamber 35 is opened on the lower side of the rotating rod 23. A rigid film is fixedly connected to the lower side of the storage chamber 35.

[0035] The storage chamber 35 is connected to the delivery chamber 34. The delivery chamber 34 is T-shaped. A cross-shaped slit is opened in the center of the hard film 36. An injection hole 37 is opened through the front side of the inside of the rotating rod 23. The injection hole 37 is connected to the storage chamber 35. A sealing column 38 is inserted into the inside of the injection hole 37.

[0036] By adopting the above technical scheme, when the weight sleeve 293 contacts the gear 17 and the rotating rod 23 continues to move downward, the second sliding block 292 inside the weight sleeve 293 will slide inside the second sliding groove 291 on the outside, and when the second sliding block 292 contacts the extrusion rod 31 inside the second sliding groove 291, the second sliding block 292 will push the extrusion column upward, so that the piston disc 32 on the upper side of the extrusion column slides inside the piston cavity 33. At this time, the piston disc 32 will compress the air inside the piston cavity 33, and the compressed air will enter the storage cavity 35 through the conveying cavity 34, so that the compressed air pushes the lubricant inside the storage cavity 35. At this time, the lubricant inside the storage cavity 35 will extrude the hard film, and finally fall on the connection between the workpiece and the gear 17. The self-repairing property of the hard film will block the lubricant inside the storage cavity 35 after resetting. When it is necessary to add lubricant, the plugging column 38 can be taken out from the injection hole 37, and then the lubricant can be injected into the storage cavity 35 through the injection hole 37. Since the lubricant can be automatically discharged during the correction of the gear 17, the lubricant falls into the assembly of the gear 17 inside the workpiece. On the one hand, the gear 17 can be lubricated, so that the gear 17 can be smoothly assembled. On the other hand, the transmission efficiency of the gear 17 can be guaranteed.

[0037] Working principle: after the electric guide rail 21 sends two gears 17 to the inside of the same hollow groove 27, the electric push rod 16 pushes the moving seat 14 to drive the driving motor 22 and the rotating rod 23 to move downwards, when the rotating rod 23 is inserted into the inside of the gear 17, the first magnetic block 25 contacts with the inner wall of the gear 17, so that the driving motor 22 drives the rotating rod 23 to rotate slowly, which drives the two gears 17 to rotate temporarily in the hollow groove 27, before the first magnetic block 25 passes through the gear 17 and is in the inner cavity of the tooth ring 271, the second magnetic block 282 supports the gear 17 entering the inside of the tooth ring 271, and the first magnetic block 25 and the second magnetic block 282 repel each other, so that the first magnetic block 25 is retracted into the first embedded groove 24, after the first magnetic block 25 and the second magnetic block 282 move away, the gear 17 enters the inside of the workpiece smoothly under the guidance of the rotating rod 23 and the first magnetic block 25, then the driving motor 22 drives the rotating rod 23 to rotate several turns, so that the two gears 17 rotate in the workpiece, when the rotating rod 23 continues to move downwards, the first magnetic block 25 will pass through the counterweight sleeve 293, and when the rotating rod 23 contacts with the workpiece, the gear 17 on the outside of the rotating rod 23 enters the inside of the workpiece for assembly, then the counterweight sleeve 293 presses the gear 17, when the rotating rod 23 drives the gear 17 to rotate, the rotating rod 23 moves upwards, because the counterweight sleeve 293 always presses the gear 17, so that the rotating rod 23 and the first magnetic block 25 are separated from the inside of the gear 17, then the rotating rod 23 moves upwards to drive the first magnetic block 25 to re-enter the inside of the counterweight sleeve 293, so that the rotating rod 23 can also drive the counterweight sleeve 293 to move upwards, when the counterweight sleeve 293 contacts with the gear 17 and the rotating rod 23 continues to move downwards, the second sliding block 292 contacts with the extrusion rod 31 in the second sliding groove 291, so that the piston disc 32 on the upper side of the extrusion column slides in the piston cavity 33, at this time, the piston disc 32 compresses the air in the piston cavity 33, and the compressed air enters the storage cavity 35 through the conveying cavity 34, so that the compressed air pushes the lubricant in the storage cavity 35, at this time, the lubricant in the storage cavity 35 extrudes the hard film, and finally falls on the connection between the workpiece and the gear 17.

[0038] The above merely shows the preferred embodiments of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical solution and the improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
