Abstract

An assembling device is disclosed. The assembling device is used to assemble a plastic frame and a back plate together and includes: a pressing mechanism configured to press a region of the plastic frame; and a supporting device. The supporting device includes: a supporting platform configured to support the back plate and the plastic frame; and a supporting frame configured to support the pressing mechanism. The pressing mechanism is configured to contact the plastic frame at least one contact point, and a direction of a resultant force of forces applied at the at least one contact point by the pressing mechanism is at an acute angle with respect to a plane where a top surface of the plastic frame lies.

First claim

What is claimed is:

1. An assembling device, configured for assembling a plastic frame and a back plate together, the assembling device comprising:
a pressing mechanism configured to press two opposite regions of the plastic frame; and
a supporting device comprising:
a supporting platform configured to support the back plate and the plastic frame; and
a supporting frame configured to support the pressing mechanism,

wherein the pressing mechanism is configured to contact the plastic frame at at least one pair of opposite contact points, such that a direction of a resultant force of forces applied at each of the at least one pair of opposite contact points by the pressing mechanism is at an acute angle with respect to a plane where a top surface of the plastic frame lies, and the resultant force of the forces applied at each of the at least one pair of opposite contact points by the pressing mechanism is directed towards a position between the at least one pair of opposite contact points.

2. The assembling device according to claim 1 , wherein the direction of the resultant force is at an angle of 45 degrees with respect to the plane where the top surface of the plastic frame lies.

3. An assembling device, configured for assembling a plastic frame and a back plate together, the assembling device comprising:
a pressing mechanism configured to press a region of the plastic frame; and
a supporting device comprising:
a supporting platform configured to support the back plate and the plastic frame; and
a supporting frame configured to support the pressing mechanism,
wherein the pressing mechanism is configured to contact the plastic frame at at least one contact point, and a direction of a resultant force of forces applied at the at least one contact point by the pressing mechanism is at an acute angle with respect to a plane where a top surface of the plastic frame lies, and
wherein the pressing mechanism comprises a pressing roller configured to roll along an outer edge of the plastic frame.

4. The assembling device according to claim 3 ,
wherein an outer circumferential surface of the pressing roller is provided with an annular groove having a V-shaped cross section, and the annular groove has a first inclined surface and a second inclined surface that intersect each other; and
wherein the first inclined surface is configured to contact the top surface of the plastic frame, the second inclined surface is configured to contact a side surface of the plastic frame, and a direction of a resultant force of forces applied by the first and second inclined surfaces to the plastic frame is at an acute angle with respect to the top surface of the plastic frame.

5. An assembling device, configured for assembling a plastic frame and a back plate together, the assembling device comprising:
a pressing mechanism configured to press a region of the plastic frame; and
a supporting device comprising:
a supporting platform configured to support the back plate and the plastic frame; and
a supporting frame configured to support the pressing mechanism,
wherein the pressing mechanism is configured to contact the plastic frame at at least one contact point, and a direction of a resultant force of forces applied at the at least one contact point by the pressing mechanism is at an acute angle with respect to a plane where a top surface of the plastic frame lies, and
wherein the pressing mechanism comprises a first pressing roller configured to roll along the top surface of the plastic frame and a second pressing roller configured to roll along a side surface of the plastic frame, and a resultant force of forces applied by the first and second pressing rollers to the plastic frame is at an acute angle with respect to the top surface of the plastic frame.

6. The assembling device according to claim 1 , wherein the pressing mechanism comprises a pressing block configured to slide along an outer edge of the plastic frame.

7. The assembling device according to claim 1 , wherein the supporting frame comprises a rail mechanism and a sliding frame slidably mounted on the rail mechanism in an extension direction of the rail mechanism which is the same as an extension direction of an outer edge of the plastic frame, and the pressing mechanism is fixedly mounted to the sliding frame.

8. The assembling device according to claim 7 , wherein the rail mechanism comprises two sliding rails disposed in parallel with each other and fixed to the supporting frame, and the sliding frame is configured to slidably cooperate with the two sliding rails.

9. The assembling device according to claim 7 , wherein:
the supporting platform is provided with a fixing structure configured for fixing the back plate,
the fixing structure comprises a raised platform protruding from a top surface of the supporting platform and at least two adjusting devices detachably connected to the top surface of the supporting platform,
the raised platform is configured to match and locate a recess provided in a surface of the back plate facing away from the plastic frame; and
each of the at least two adjusting devices is configured to abut against a corresponding side surface of the back plate so as to fix the back plate on the raised platform.

10. The assembling device according to claim 9 , wherein:
each of the at least two adjusting devices is provided with an elongate hole having a length direction perpendicular to the extension direction of the rail mechanism;
a surface of the supporting platform is provided with a screw hole aligned in position with the elongate hole; and
each of the at least two adjusting devices is fixed to the supporting platform by a screw passing through the elongate hole and threaded to the screw hole.

11. The assembling device according to claim 1 , further comprising a driving device configured to drive the pressing mechanism to move along an outer edge of the plastic frame.

12. The assembling device according to claim 1 , wherein the pressing mechanism comprises a pressing roller configured to roll along an outer edge of the plastic frame.

13. The assembling device according to claim 12 ,
wherein an outer circumferential surface of the pressing roller is provided with an annular groove having a V-shaped cross section, and the annular groove has a first inclined surface and a second inclined surface that intersect each other; and
wherein the first inclined surface is configured to contact the top surface of the plastic frame, the second inclined surface is configured to contact a side surface of the plastic frame, and a direction of a resultant force of forces applied by the first and second inclined surfaces to the plastic frame is at an acute angle with respect to the top surface of the plastic frame.

14. The assembling device according to claim 1 , wherein the pressing mechanism comprises a first pressing roller configured to roll along the top surface of the plastic frame and a second pressing roller configured to roll along a side surface of the plastic frame, and a resultant force of forces applied by the first and second pressing rollers to the plastic frame is at an acute angle with respect to the top surface of the plastic frame.
