[0058] Example

[0059] This embodiment is intended to promote the solution of the problem that in the existing clamp, after the clamping action is completed, there is still a certain angle between the target object 6 and the film body 7 in the top view (such as Figure 8 ), causing the film body 7 to be attached crookedly. To this end, this embodiment provides a clamping device and a film laminating machine, wherein one end of the target object 6 can simultaneously abut the first abutting member 21 and the second abutting member 22 of the first clamping mechanism 2, and the other end abuts the second clamping mechanism 3, forming a triangular contact with the two ends of the target object 6. During the clamping process, the target object 6 is straightened and the angle between the target object 6 and the film body 7 is eliminated.

[0060] Reference Figure 1 and 7 As shown, a clamping device includes:

[0061] A fixture base 1, the fixture base 1 includes a bearing surface 11 for placing a target object 6;

[0062] A first clamping mechanism 2 is provided on the clamp seat 1 and is capable of sliding along one end of the bearing surface 11;

[0063] A second clamping mechanism 3 is provided on the clamp seat 1 and is capable of sliding along the other end of the bearing surface 11;

[0064] a power mechanism 4, which is disposed on the clamp base 1 and is capable of driving the first clamping mechanism 2 and the second clamping mechanism 3 to move relative to each other, so that the first clamping mechanism 2 and the second clamping mechanism 3 can clamp the target object 6;

[0065] The first clamping mechanism 2 includes a first abutting member 21 and a second abutting member 22 . The first abutting member 21 and the second abutting member 22 can abut against one end of the target object 6 simultaneously.

[0066] Reference Figure 2 As shown, further, the first clamping mechanism 2 also includes:

[0067] The first sliding seat 23 is provided with a first traction member 24 for connecting to the power mechanism 4 ; the first abutment member 21 is connected to the first sliding seat 23 , and the first sliding seat 23 can slide on the clamp seat 1 to drive the first abutment member 21 to move on the bearing surface 11 .

[0068] The second abutting member 22 is rotatably connected to the first sliding seat 23; the first abutting member 21 is rotatably connected to the first sliding seat 23;

[0069] The elastic reset member 25 is disposed on the first sliding seat 23 , and elastic reset ends of the elastic reset member 25 are respectively connected to the first abutting member 21 and the second abutting member 22 .

[0070] Reference Figure 2 As shown, further, the ends of the first abutment member 21 and the second abutment member 22 are both provided with a rolling portion 26. When the first sliding seat 23 moves toward the target object, the rolling portion 26 can slide along the end surface of the target object, and the first abutment member 21 and the second abutment member 22 can be relatively opened. It should be added that the rolling portion 26 of this embodiment includes a roller 261, which is protruding and can rotate freely. The roller 261 is rotatably connected to the ends of the first abutment 21 and the second abutment 22 through the rotating shaft 262; by rolling instead of sliding, the friction between the target object 6 is reduced, that is, the loss to the first abutment 21 and the second abutment 22 is reduced, and scratches on the target object are avoided. Among them, the first abutment 21 and the second abutment 22 are relatively unfolded in a V shape, and the unfolding process is the process of clamping and returning the target object 6 to the center. The elastic return member 25 can be a torsion spring, and the movable ends of the torsion spring are pressed on the first abutment 21 and the second abutment 22 respectively, pushing the first abutment 21 and the second abutment 22 forward. When the roller is subjected to the relative clamping external force, the return force of the torsion spring in the clamping process pushes it toward the target object in the opposite direction, so that the other end of the target object is aligned with the clamp and returned to the center. In this embodiment, the first abutting member 21 and the second abutting member 22 can perform multiple clamping actions on the target object to achieve a better clamping and straightening effect, that is, a deviation correction effect.

[0072] A second sliding seat 31 is provided with a second traction member 311 for connecting to the power mechanism 4;

The rotating connector 32 is rotatably connected to the second sliding seat 31; the target object 6 can be inserted into the first plug-in portion 321, rotate around the rotating connector 32 and be placed flat on the supporting surface 11. Specifically, the second sliding seat 31 is provided with a bracket 312 that is compatible with the rotating connecting member 32, and the two sides of the bracket 312 are rotatably connected to the two ends of the rotating connecting member 32. Specifically, the rotating connecting member 32 is a circular shaft, and a first plug-in portion 321 is provided on one side of the middle part of the circular shaft, and circular protrusions 322 are provided at both ends of the circular shaft; support plates 313 are provided on both sides of the bracket 312, and a movable groove 3131 is provided on the support plate 313. The circular protrusion 322 is inserted into the movable groove 3131 and can slide along the movable groove 3131 and can also rotate along the movable groove 3131; a movable window 3121 is provided in the middle of the bracket 312 for rotating the first plug-in portion 321 at any angle. The purpose of providing the movable groove 3131 is to adapt to different target objects 6, such as target objects of different thicknesses, whose charging interface heights are different. To this end, when the target object is placed flat on the support surface 11, the movable groove 3131 can adjust the height of the rotating connector 32 adaptively, ensuring that the target object is flat on the support surface 11 without causing the other end of the target object to sag or tilt. The circular protrusion 322 in the movable groove 3131 also allows the first plug-in portion 321 to rotate perpendicular to the support surface 11, making it easier for the user to insert the target object into the first plug-in portion 321 and then rotate it around the rotating connector 32 to place it flat on the support surface 11, making it more convenient and efficient for the user to use. In some embodiments, the second clamping mechanism 3 can be fixedly connected to the clamp base 1.

When the first sliding seat 23 and the second sliding seat 31 are respectively installed in the first travel groove 122 and the second travel groove 123, the first traction member 24 is inserted on one side of the hollow area, while the second traction member 311 is inserted on the other side of the hollow area; a power mechanism 4 can be provided between the first traction member 24 and the second traction member 311 to transmit the first traction member 24 and the second traction member 311, thereby driving the first sliding seat 23 and the second sliding seat 31 to move.

The output end of the motor 41 is connected to the gear member 42. Specifically, the gear member 42 can be a stepped gear, which is a large gear and a small gear stacked concentrically. The small gear is used to mesh with the rack portion 241 of the first traction member 24 and / or the second traction member 311. The clamp seat 1 also includes a bottom cover plate 14, which is detachably connected to the bottom of the clamp body 12. A receiving groove 141 for accommodating the stepped gear is provided in the middle of the bottom cover plate 14. In addition to the stepped gear, the receiving groove 141 also has a driving gear 411 meshing with the large gear installed therein. The motor 41 is installed at the bottom of the bottom cover plate 14, and the output shaft of the motor 41 passes through the bottom cover plate 14 and is connected to the driving gear 411.

[0079] Reference Figure 5 As shown, the clamping device of this embodiment further includes a membrane positioning and installation component 5; the membrane positioning and installation component 5 includes:

[0080] A first positioning mounting member 51 is detachably connected to the fixture base 1 . A first latching protrusion 511 is provided on the top of the first positioning mounting member 51 . The first latching protrusion 511 is used to latch the positioning hole 71 of the membrane 7 .

[0081] The second positioning mounting member 52 is detachably connected to the clamp seat 1 , and a second latching protrusion 521 is provided on the top of the second positioning mounting member 52 ; the second latching protrusion 521 is used to latch the positioning hole 71 of the membrane 7 ;

[0082] The first clamping mechanism 2 and the second clamping mechanism 3 clamp the target object, and the film 7 supported by the first positioning mounting member 51 and the second positioning mounting member 52 corresponds to the position of the target object.

[0083] Reference Figure 6 As shown, in order to make the first abutment 21 and the second abutment 22 unfold synchronously and synchronously return the end of the target object 6, the first abutment 21 is provided with a first meshing portion 211, and the second abutment 22 is provided with a second meshing portion 221, and the first meshing portion 211 and the second meshing portion 221 are meshed.

[0084] Reference Figure 3As shown, in order to make the rotating connector 32 adapt to the charging interface of different target objects 6, the rotating connector 32 also includes a second connector 323, and the first connector 321 or the second connector 323 can be a plastic part adapted to the Micro USB interface, Type-C interface, and Lightning interface.

[0085] Reference Figure 5 As shown, the membrane positioning and installation assembly 5 further includes support members 53 for supporting both sides of the middle portion of the membrane 7 , and the middle support member 53 of the membrane 7 is detachably connected to the clamp seat 1 .

[0086] The method of using this embodiment includes: aligning the charging interface of the target object 6 with the first plug-in portion 321 and inserting it, which is not fully inserted, with the target object 6 below, and the target object 6 is placed flat on the supporting surface. Due to manual operation errors, a certain angle will be formed between the target object 6 and the pre-placed film 7, such as Figure 8 As shown. During the clamping process of the target object 6, the protruding portion of the inclined surface at the right end of the target object 6 will first hit the roller of the first abutting member 21, and the roller will push the target object 6 back to its original position slowly, so that the left end of the target object 6 approaches the second sliding seat 31, and the end faces are gradually aligned. The roller of the second abutting member 22 that continues to clamp also contacts the right end face of the target object 6. Under the action of the elastic force of the torsion spring, the two rollers press against the right end of the target object 6, clamping the target object 6 with the left end as the reference. At this time, the rolling friction between the rollers and the right end of the target object 6 is very small, and the target object 6 will automatically align under the thrust of the rollers. Moreover, the first abutting member 21 and the second abutting member 22 will rotate relative to each other during the clamping process, and the angle between the two will become larger and larger. The closer the rollers are to the edge of the end of the target object 6, the stronger the force for the target object 6 to return to its original position. Because there is a certain friction between the target object 6 and the pad, the centering effect of the target object 6 is affected. In order to avoid the influence of the friction on the centering of the target object 6, in the control of the machine, the clamping action of the target object 6 is implemented for three consecutive clampings, that is, the first time, the motor 41 is started to clamp the target object 6 into place, the second time, the motor 41 is reversed to release the target object 6, and then the motor 41 is rotated forward to clamp the target object 6 into place, and the third time, the motor 41 is reversed to release the target object 6, and then the motor 41 is rotated forward to clamp the target object 6 into place. After three clampings, the influence of the friction on the centering of the target object 6 can be eliminated, and the correction effect can be achieved.

[0087] This embodiment also provides a film laminating machine, which uses the above-mentioned clamping device, that is, the film laminating machine includes the above-mentioned clamping device. The film laminating machine can apply a protective mold to the display surface of the display screen on the target object 6 while clamping the target object 6 through the clamping device.

[0088] It should be noted that the target object 6 that the clamping device of the embodiment of the present application is used to clamp is not limited to a mobile phone, but can also be other electronic devices with a display screen or a screen.

[0089] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
