Description

Technical Field

[0001] This utility model relates to the field of mobile phone assembly and manufacturing technology, specifically to a high-speed automatic flat-laying equipment for auxiliary materials. Background Technology

[0002] In the process of mobile phone manufacturing, the manufacturing of the mobile phone casing is equally important. The mobile phone casing has a variety of auxiliary materials, some of which need to be processed into flat materials before being installed on the casing for flat application.

[0003] In the "Automatic Flat Laying Mechanism for Mobile Phone Accessories" authorized announcement number "CN214779674U", a flat material belt is fed onto a conveyor belt. The positioning holes on both sides of the flat material belt engage with the positioning protrusions on the conveyor belt surface to position the flat material belt and ensure its smooth movement on the conveyor belt, thereby improving the positioning accuracy of the flat material belt on the conveyor belt. However, this method can only convey flat material belts of a certain width, which has low practicality. At the same time, when conveying the flat material belt, it is necessary to ensure the tension of the flat material belt because the positioning holes on both sides of the flat material belt need to engage with the positioning protrusions on the conveyor belt surface. However, the document does not include a device for tensioning the flat material belt. Therefore, during the conveying process, there may be situations where the positioning holes on both sides of the flat material belt do not align with the positioning protrusions on the conveyor belt surface, affecting the stable conveying of the flat material belt. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed automatic flat-laying device for auxiliary materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed automatic flat-laying device for auxiliary materials, comprising a mounting base, with drive shafts symmetrically and rotatably mounted at both ends of the mounting base, and drive wheels slidably mounted at both ends of the drive shafts. The drive wheels rotate with the rotation of the drive shafts. A conveyor belt is driven between the two drive wheels on the same side, and positioning protrusions are equidistantly arranged on the conveyor belt. Connecting rods are symmetrically mounted at one end of the mounting base, and a lifting roller is rotatably mounted between one end of the two connecting rods. The lifting roller can be raised and lowered, and a flat material belt is positioned above the lifting roller.

[0006] As a further preferred embodiment of this technical solution, a rotating shaft is symmetrically mounted inside one end of the mounting base, the end of the connecting rod away from the lifting roller is fixedly connected to the rotating shaft, a torsion spring is sleeved on the outer side of one end of the rotating shaft, one end of the torsion spring is fixedly connected to the connecting rod, and the other end of the torsion spring is fixedly connected to the interior of the mounting base.

[0007] As a further preferred embodiment of this technical solution, a guide roller is rotatably mounted on one end of the mounting base near the lifting roller.

[0008] As a further preferred embodiment of this technical solution, a drive motor is fixedly installed on one side of the mounting base corresponding to one of the drive shafts. The output end of the drive motor is fixedly connected to one end of the drive shaft. Limiting blocks are symmetrically fixedly installed in the middle of the drive shaft. Limiting grooves are symmetrically formed on the inner ring of the drive wheel. The limiting grooves are slidably connected to the limiting blocks.

[0009] As a further preferred embodiment of this technical solution, a bidirectional screw is rotatably mounted in the middle of the mounting base via a bearing. An adjusting motor is fixedly mounted on one side of the mounting base corresponding to the position of the bidirectional screw. The output end of the adjusting motor is fixedly connected to one end of the bidirectional screw. Limiting rods are symmetrically fixedly mounted in the middle of the mounting base. Pushing frames are symmetrically slidably mounted between the two limiting rods. The middle parts of the two pushing frames are threadedly connected to both ends of the bidirectional screw. The ends of the pushing frames are located on both sides of the transmission wheel, and the ends of the pushing frames are slidably disposed with the transmission shaft.

[0010] As a further preferred embodiment of this technical solution, a pressure plate is fixedly installed at the bottom end of the pusher frame.

[0011] This utility model provides a high-speed automatic flat-laying device for auxiliary materials, which has the following beneficial effects:

[0012] (1) The present invention uses the torsion spring to rotate the shaft, which will cause the connecting rod to be in an upward tilt at all times. The lifting roller between the two connecting rods will continuously lift the flat material belt to keep the flat material belt taut. At the same time, the guide roller will guide the flat material belt to be stably and horizontally transported to the conveyor belt.

[0013] (2) This utility model drives the bidirectional screw to rotate by adjusting the motor. The middle part of the two push frames is connected to the threaded ends of the bidirectional screw, which will drive the push frames to move in opposite directions or in opposite directions along the trajectory of the limit rod. The end of the push frame will push the transmission wheel to slide along the outside of the transmission shaft, thereby adjusting the distance between the two conveyor belts. It can be used to convey flat material belts of different widths. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a high-speed automatic flat-laying device for auxiliary materials includes a mounting base 1. A drive shaft 2 is symmetrically mounted on both ends of the mounting base 1 via bearings. Drive wheels 3 are slidably mounted on both ends of the drive shaft 2, rotating with the drive shaft 2. A conveyor belt 4 is driven between the two drive wheels 3 on the same side. Positioning protrusions 5 are equidistantly arranged on the conveyor belt 4. Connecting rods 6 are symmetrically mounted on one end of the mounting base 1. A lifting roller 7 is rotatably mounted between the ends of the two connecting rods 6 via bearings. The lifting roller 7 can be raised and lowered. A flat-laying belt is positioned above the lifting roller 7. A guide roller 10 is rotatably mounted on the end of the mounting base 1 near the lifting roller 7. A rotating shaft 8 is symmetrically rotatably mounted inside one end of the mounting base 1. The end of the connecting rod 6 away from the lifting roller 7 is fixedly connected to the rotating shaft 8. A torsion spring 9 is sleeved on the outer side of one end of the rotating shaft 8. One end of the torsion spring 9 is fixedly connected to the connecting rod 6, and the other end of the torsion spring 9 is fixedly connected to the inside of the mounting base 1. During the conveying of the flat material belt, the torsion of the rotating shaft 8 by the torsion spring 9 will cause the connecting rod 6 to be in an inclined upward state at all times. The lifting roller 7 between the two connecting rods 6 will continuously lift the flat material belt to keep the flat material belt taut. At the same time, the guide roller 10 guides the flat material belt to be stably and horizontally conveyed to the conveyor belt 4. By driving the transmission wheel 3 to slide along the outer side of the transmission shaft 2, the distance between the two conveyor belts 4 can be adjusted to convey flat material belts of different widths.

[0021] like Figures 1 to 4 As shown, a drive motor 11 is fixedly installed on one side of the mounting base 1 corresponding to one of the drive shafts 2. The output end of the drive motor 11 is fixedly connected to one end of the drive shaft 2. Limiting blocks 12 are symmetrically fixedly installed in the middle of the drive shaft 2. Limiting grooves 13 are symmetrically opened on the inner ring of the drive wheel 3. The limiting grooves 13 are slidably connected to the limiting blocks 12.

[0022] The drive motor 11 drives the drive shaft 2 to rotate. The limit groove 13 on the inner ring of the drive wheel 3 and the limit block 12 on the drive shaft 2 limit the drive wheel 3 to rotate synchronously, which can drive the conveyor belt 4 to operate for conveying flat material belts.

[0023] like Figures 1 to 4 As shown, a bidirectional screw 14 is rotatably mounted on the middle of the mounting base 1 via a bearing. An adjusting motor 15 is fixedly mounted on one side of the mounting base 1 corresponding to the position of the bidirectional screw 14. The output end of the adjusting motor 15 is fixedly connected to one end of the bidirectional screw 14. Limiting rods 16 are symmetrically fixedly mounted on the middle of the mounting base 1. Pushing frames 17 are symmetrically slidably mounted between the two limiting rods 16. The middle parts of the two pushing frames 17 are respectively threaded to both ends of the bidirectional screw 14. The ends of the pushing frames 17 are located on both sides of the transmission wheel 3. The ends of the pushing frames 17 are slidably disposed with the transmission shaft 2.

[0024] By adjusting the motor 15 to drive the bidirectional screw 14 to rotate, the middle part of the two push frames 17 is respectively connected to the two ends of the bidirectional screw 14 by threads, which will drive the push frames 17 to move in opposite directions along the trajectory of the limit rod 16. The end of the push frame 17 will push the transmission wheel 3 to slide along the outside of the transmission shaft 2, thereby adjusting the distance between the two conveyor belts 4.

[0025] like Figures 1 to 4 As shown, a pressure plate 18 is fixedly installed at the bottom end of the pusher frame 17.

[0026] When the flat material belt is conveyed onto the conveyor belt 4, the front edge of the flat material belt is embedded under the pressure plate 18. As the push frame 17 moves, the pressure plate 18 will move along with the push frame 17 to maintain the synchronous movement of the pressure plate 18 and the conveyor belt 4, thereby achieving continuous positioning of the flat material belt.

[0027] This utility model provides a high-speed automatic flat-laying device for auxiliary materials, the specific working principle of which is as follows:

[0028] When the device is in use, the flat material belt is conveyed onto the conveyor belt 4. The front edge of the flat material belt is embedded under the pressure plate 18. The positioning holes on both sides of the flat material belt will be locked onto the positioning protrusions 5 on the conveyor belt 4. The drive motor 11 drives the drive shaft 2 to rotate. The limiting groove 13 of the inner ring of the drive wheel 3 and the limiting block 12 on the drive shaft 2 limit the drive wheel 3 to rotate synchronously, which can drive the conveyor belt 4 to operate for conveying the flat material belt.

[0029] During the conveying of the flat material belt, the torsion of the rotating shaft 8 by the torsion spring 9 will cause the connecting rod 6 to be in an upward tilt at all times. The lifting roller 7 between the two connecting rods 6 will continuously lift the flat material belt to keep it taut. At the same time, the guide roller 10 will guide the flat material belt to be stably and horizontally conveyed onto the conveyor belt 4.

[0030] When conveying flat material belts of different widths, the motor 15 drives the bidirectional screw 14 to rotate. The middle part of the two push frames 17 is connected to the two ends of the bidirectional screw 14 by threads, which will drive the push frames 17 to move in opposite directions along the trajectory of the limit rod 16. The end of the push frame 17 will push the transmission wheel 3 to slide along the outside of the transmission shaft 2, thereby adjusting the distance between the two conveyor belts 4. This is used to convey flat material belts of different widths. While the push frame 17 moves, the pressure plate 18 will move with the push frame 17 to keep the pressure plate 18 and the conveyor belt 4 moving synchronously, so as to achieve continuous positioning of the flat material belt.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
