[0039] This utility model provides a driving mechanism, such as Figures 1-6 As shown.

[0040] A drive mechanism includes a mounting plate 10, a movable arm 20, a crossbeam 30, a first roller assembly, a power component 40, a first drive wheel 41, and a first synchronous belt 42, wherein the crossbeam 30 is slidably engaged with the movable arm 20.

[0041] The first roller group is perpendicular to the sliding direction of the crossbeam 30; the power component 40 is mounted on the mounting plate 10 and includes a drive shaft.

[0042] The first drive wheel 41 is mounted on the drive shaft; the first synchronous belt 42 is wound around the first drive wheel 41 and the first roller group, one side of the first synchronous belt 42 is fixed to the crossbeam 30, and the first synchronous belt 42 drives the crossbeam 30 to slide back and forth.

[0043] The lower belt body 422 of the first synchronous belt 42 of this utility model is fixed to the crossbeam 30. The lower belt body 422 drives the crossbeam 30 to slide back and forth, which can realize the crossbeam 30 to move back and forth along the M1 direction. The driving mechanism is simple and has high transmission efficiency.

[0044] The aforementioned power component 40 includes a motor, the motor's shaft of which is connected to the drive shaft via a coupling.

[0045] The specific arrangement of the first roller group mentioned above is as follows:

[0046] The first roller group includes a first driven roller 43, a second driven roller 44, a third driven roller 45, and a fourth driven roller 46. The first driven roller 43 and the second driven roller 44 are rotatably connected to the mounting plate 10. The first driven roller 43 and the second driven roller 44 are respectively placed on both sides of the first driving roller 41 in the axial direction.

[0047] The third driven wheel 45 and the fourth driven wheel 46 are rotatably connected to the inner wall of the movable arm 20. The third driven wheel 45 and the fourth driven wheel 46 are located at the inner end and the outer end of the movable arm 20, respectively.

[0048] The first synchronous belt 42 is sequentially wound around the first driving pulley 41, the first driven pulley 43, the third driven pulley 45, the fourth driven pulley 46, and the second driven pulley 44. That is, the two ends of the first synchronous belt 42 are the third driven pulley 45 and the fourth driven pulley 46. The upper belt body 421 of the first synchronous belt 42 is wound around the first driving pulley 41, the first driven pulley 43, and the second driven pulley 44, and the lower belt body 422 is fixedly connected to the crossbeam 30 through the first pressure plate 47.

[0049] The first synchronous belt 42 and the first roller group mentioned above constitute the first set of belt drive system. The first synchronous belt 42 and the first roller group are disposed on the inner wall of one side of the movable arm 20. This utility model additionally provides a second set of belt drive system, which is disposed on the inner wall of the other side of the movable arm 20. The second set of belt drive system is as follows.

[0050] The drive mechanism also includes a second drive wheel 51, a second roller group and a second synchronous belt 52, with the second drive wheel 51 connected in series with the first drive wheel 41 on the drive shaft;

[0051] The axis of the second roller group is perpendicular to the sliding direction of the crossbeam 30; one end of the second synchronous belt 52 is fixed to the inner end of the moving arm 20 and the other end is fixed to the outer end of the moving arm 20, that is, one end of the second synchronous belt 52 is fixed to the inner end of the moving arm 20 through the second pressure plate 55 and the other end is fixed to the outer end of the moving arm 20 through the third pressure plate 56.

[0052] The second synchronous belt 52 is wound around the second drive wheel 51 and the second roller group from the inner end of the moving arm 20;

[0053] The movable arm 20 is slidably engaged with the mounting plate 10, and the second synchronous belt 52 can drive the movable arm 20 to slide back and forth in the same direction as the sliding direction of the crossbeam 30.

[0054] like Figure 4 As shown, when the first synchronous belt 42 drives the crossbeam 30 to slide to the right along the M1 direction, the lower belt body 422 will move to the right along the M1 direction, so that the crossbeam 30 slides to the right relative to the moving arm 20 at a speed of V1.

[0055] like Figure 5 As shown, the second synchronous belt 52 is driven by the second drive wheel 51. That is, the second drive wheel 51, the first pulley 53, and the second pulley 54 remain in the same position relative to the mounting plate 10. The second synchronous belt 52 drives the moving arm 20 to slide to the right, so that the moving arm 20 slides to the right relative to the mounting plate 10 at a speed of V2.

[0056] The two sets of pulley transmission systems mentioned above can achieve a total speed of V = V1 + V2 for the crossbeam 30. The drive mechanism of this utility model can drive the crossbeam 30 to move at high speed, meeting the requirements of high-speed production.

[0057] The diameter of the first driving wheel 41 of the drive mechanism is D1, and the diameter of the second driving wheel 51 is D2, satisfying 1≤D1 / D2. D1 / D2 can be 1.1, 1.2, 1.3, or 1.4.

[0058] By adjusting the diameter D1 of the first drive wheel 41, the sliding speed V2 of the moving arm 20 is adjusted, thereby adjusting the moving speed V of the crossbeam 30.

[0059] Preferably, 1.5 ≤ D1 / D2 ≤ 3, where D1 / D2 can be 1.6, 1.8, 2.0, 2.2, 2.4, 2.6, or 2.8. Adjusting the diameter of the first drive wheel 41 to be larger than the second drive wheel 51 increases the sliding speed V2 of the moving arm 20, further increasing the moving speed V of the crossbeam 30, thus meeting the requirements of high-cycle production.

[0060] The specific arrangement of the first roller group mentioned above is as follows:

[0061] The second roller assembly includes a first pulley 53 and a second pulley 54, with the first pulley 53 being rotatably connected to the mounting plate 10.

[0062] The second pulley 54 is rotatably connected to the mounting plate 10. The first pulley 53 and the second pulley 54 are respectively placed on both sides of the second drive wheel 51 along the axis. The first pulley 53 and the second pulley 54 are located inside the moving arm 20. The axes of the first pulley 53 and the second pulley 54 are parallel to the axis of the second drive wheel 51.

[0063] The second synchronous belt 52 is sequentially wound around the first pulley 53, the second drive pulley 51 and the second pulley 54 from the inner end of the moving arm 20.

[0064] The drive mechanism also includes a first guide rail 21 and a second guide rail 22. The two first guide rails 21 are fixed to the top of the movable arm 20. The two first guide rails 21 are parallel to each other and their length direction is consistent with the arm length direction of the movable arm 20.

[0065] Two second guide rails 22 are fixed to the bottom of the movable arm 20. The two second guide rails 22 are parallel to each other and their length direction is consistent with the arm length direction of the movable arm 20.

[0066] The slider at the bottom of the mounting plate 10 is slidably connected to the first guide rail 21 at the top of the movable arm 20, and the slider at the top of the crossbeam 30 is slidably connected to the second guide rail 22 at the bottom of the movable arm 20.

[0067] The first guide rail 21 and the second guide rail 22 are respectively arranged at the top and bottom of the movable arm 20, making the drive mechanism of this utility model more compact.

[0068] In order to achieve synchronous lifting of the mounting plate 10 and the moving arm 20, the drive mechanism of this utility model also includes a vertical guide rail 61, a column 62, a rack 63 and a lifting motor 64, with the vertical guide rail 61 fixed to the frame 1.

[0069] The bottom end of the column 62 is fixed to the mounting plate 10, the back of the column 62 is fixed to the slider, the column 62 is slidably engaged with the vertical guide rail 61, and the side of the column 62 is fixed to the rack 63.

[0070] The lifting motor 64 is fixed to the frame 1, and the drive shaft of the lifting motor 64 meshes with the rack 63 on the side of the column 62 for transmission.

[0071] The material of this invention can be flexible material such as paper, plastic film, cloth, metal foil, etc. The specific type of material is not limited. The following is an example of paper A.

[0072] This utility model also provides a material transfer device 100, including a first clamping unit 30a and the aforementioned driving mechanism, such as... Figure 6 As shown, the first clamping unit 30a includes a movable clamping block 31, a fixed clamping block 32, and a cylinder 33.

[0073] The movable clamping block 31 includes a first bottom surface 311 and a first clamping surface 312. The first bottom surface 311 of the movable clamping block 31 can press the paper A. The angle between the first bottom surface 311 and the first clamping surface 312 is an acute angle θ.

[0074] The fixed clamping block 32 includes a second bottom surface 321 and a second clamping surface 322. The second bottom surface 321 can clamp the material. The second clamping surface 322 is parallel to the first clamping surface 312 of the movable clamping block 31. The fixed clamping block 32 is in a first position when it is spaced apart from the movable clamping block 31. The second position is when the second clamping surface 322 of the fixed clamping block 32 is in contact with the first clamping surface 312 of the movable clamping block 31.

[0075] The cylinder 33 is mounted on the crossbeam 30. The cylinder 33 is connected to the movable clamping block 31 and the fixed clamping block 32 respectively. The cylinder 33 can drive the movable clamping block 31 to move from the first position to the second position.

[0076] The first clamping unit 30a of this utility model sets the angle θ between the first bottom surface 311 and the first clamping surface 312 of the movable clamping block 31 to an acute angle, specifically 10°≤θ≤80°. The second clamping surface 322 of the fixed clamping block 32 is parallel to the first clamping surface 312 of the movable clamping block 31. In this way, after the movable clamping block 31 and the fixed clamping block 32 clamp the paper, the short side of the paper can be bent inward during the synchronous upward movement of the mounting plate 10 and the first clamping unit 30a.

[0077] The material transfer device also includes a second clamping unit 30b, which is arranged at intervals with the first clamping unit 30a along the width direction of the material to be picked up. The second clamping unit 30b has the same structure as the first clamping unit 30a, and the first clamping surfaces 312 of the movable clamping blocks 31 of the first clamping unit and the second clamping unit are located on the same surface.

[0078] In the above embodiment, there can be two second clamping units 30b, so the material transfer device includes three clamping units arranged at intervals M2 along the paper width direction, ensuring that the paper can be stably clamped and bent to the designed angle. Alternatively, more than three second clamping units 30b can be provided. This ensures that paper A can be stably clamped and bent to the designed angle.

[0079] like Figure 7 As shown, two material transfer devices 100 are fixed on the frame 1, and the two material transfer devices 100 can operate alternately.

[0080] The following example, using paper A as the material, illustrates a paper-taking method based on the aforementioned material transfer device 100, comprising the following steps:

[0081] S10: As Figure 1 As shown, the first clamping unit 30a is located at the material picking position 401. The lifting motor 64 drives the mounting plate 10, the moving arm 20 and the first clamping unit 30a to descend synchronously. The bottom surfaces of the movable clamping block 31 and the fixed clamping block 32 of the first clamping unit 30a press against the paper surface of the paper A, that is, the paper A is pressed onto the glass B to be picked up by the movable clamping block 31 and the fixed clamping block 32.

[0082] S20: Cylinder 33 drives the movable clamping block 31 to move closer to the fixed clamping block 32, and the first clamping surface 312 of the movable clamping block 31 clamps the paper A with the second clamping surface 322 of the fixed clamping block 32.

[0083] S30: The lifting motor 64 drives the movable clamping block 31, the fixed clamping block 32 and the paper A to rise, and the part of the paper A that is rubbed by the movable clamping block 31 bends towards the side where the fixed clamping block 32 is located.

[0084] like Figure 2 As shown, the moving arm 20 and the crossbeam 30 drive the first clamping unit 30a and the paper A to slide towards the feeding position 402.

[0085] S40: As Figure 3 As shown, the moving arm 20 and the crossbeam 30 drive the first clamping unit 30a to slide to the feeding position 402, and the cylinder 33 drives the movable clamping block 31 away from the fixed clamping block 32, and the paper A falls to the feeding position 402.

[0086] S50: The moving arm 20 and the crossbeam 30 drive the first clamping unit 30a to slide to the material picking position, and repeat S10.

[0087] The above are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
