Description

Technical Field

[0001] This invention relates to the field of frame assembly technology, and more specifically, to an assembly device for frame workpieces. Background Technology

[0002] Metal frame workpieces consist of a frame base, a frame top frame, and uprights installed between the frame base and the frame top frame. In current industrial production, especially in the manufacturing of metal frame workpieces (such as triangular, square, and symmetrical polygonal frames), frame assembly and positioning are critical and complex processes. Traditional frame assembly methods often rely heavily on manual labor, which not only increases labor intensity but also easily introduces human error, making it difficult to guarantee frame dimensional accuracy and assembly quality.

[0003] Existing automated equipment and robotic systems are often designed for frames of specific shapes and sizes. Different shapes and sizes of frames require customized fixtures and tooling, which increases equipment costs and debugging difficulty. Existing solutions are still insufficient in meeting diverse production needs, especially when it is necessary to quickly switch between different models and specifications of frames, lacking sufficient flexibility and adaptability.

[0004] In summary, although existing automated equipment and robotics technologies have made some progress in the field of frame assembly, many problems and challenges remain. Therefore, it is necessary to further research and develop more efficient, precise, flexible, and intelligent frame assembly technologies and equipment to meet the growing demands of industrial production. In view of this, the applicant hereby submits this application after reviewing existing technologies. Summary of the Invention

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0042] Depend on Figures 1 to 11 As shown, this embodiment of the invention provides an assembly device for a frame workpiece, used to assemble the frame workpiece. The frame workpiece includes a frame base, a frame upper frame, and a vertical plate installed between the frame base and the frame upper frame. The frame base includes a bottom surface and side rails extending upward from the periphery of the bottom surface. The frame upper frame includes a planar portion with an annular structure and a joint portion extending downward from the planar portion. When assembled as a whole, the joint portion and the side rails are aligned. The frame upper frame can be either rectangular or symmetrical polygonal.

[0043] like Figure 1 As shown, the assembly device for a frame workpiece includes a bottom frame support assembly 1, a bottom frame positioning assembly 3, a top frame moving assembly 4, and a top frame support and positioning assembly 2.

[0044] like Figure 3 and Figure 4 As shown, the base frame support assembly 1 includes multiple quick-release seats 20, multiple support seats 21 that can be detachably engaged with the quick-release seats 20, and universal balls 22 that engage with the support seats 21. Specifically, the support seats 21 with quick-release structure can be installed at corresponding positions for different models of frame bases, thereby adapting to different models of assembled frame workpieces and greatly improving the adaptability of the assembly device. The universal balls 22 support the frame base while allowing the frame base to move freely in the horizontal direction, preventing scratches on the frame base.

[0045] like Figure 3 and Figure 4 As shown, the base frame positioning assembly 3 includes a base frame positioning base 10, a first clamping member 11 and a second clamping member 16 disposed opposite to each other and slidable along a first direction on the base frame positioning base 10, and a third clamping member 15 and a fourth clamping member 17 disposed opposite to each other and slidable along a second direction on the base frame positioning base 10. The first clamping member 11 and the second clamping member 16 are provided with mutually parallel first clamping surfaces. The third clamping member 15 and the fourth clamping member 17 are symmetrically arranged and provided with mutually parallel second clamping surfaces 13 for clamping a rectangular frame base, and mutually inclined third clamping surfaces 14 for clamping a polygonal frame base. The first clamping surfaces, the second clamping surfaces 13 and the third clamping surfaces 14 are used to clamp the side of the frame base.

[0046] Specifically, the first and second directions are perpendicular. In the first direction, the first clamping member 11 and the second clamping member 16 are driven closer together, clamping the frame base through the two parallel first clamping surfaces. In the second direction, the third clamping member 15 and the fourth clamping member 17 are driven closer together. When the frame base is rectangular, it is clamped by the parallel second clamping surface 13; when the frame base is a symmetrical polygon, it is clamped by the inclined third clamping surface 14, thus adapting to various frame base models. Furthermore, the first clamping surface, the second clamping surface 13, and the third clamping surface 14 are detachable, allowing for the replacement of the clamping surfaces to accommodate frame bases of more shapes and sizes.

[0047] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the bottom frame positioning assembly 3 further includes a first positioning and clamping drive member 18 engaged with the first clamping member 11 and the second clamping member 16, and a second positioning and clamping drive member 19 engaged with the third clamping member 15 and the fourth clamping member 17. The first positioning and clamping drive member 18 is configured to synchronously drive the first clamping member 11 and the second clamping member 16 to move closer or further apart. The second positioning and clamping drive member 19 is configured to synchronously drive the third clamping member 15 and the fourth clamping member 17 to move closer or further apart.

[0048] Specifically, the first clamping drive component and the second positioning clamping drive component 19 are screw-slider mechanisms. These mechanisms synchronously drive the first clamping component 11 and the second clamping component 16, as well as the third clamping component 15 and the fourth clamping component 17, ensuring the center position of the frame base by centering and clamping it. In other embodiments, one of the synchronously driven clamping components can be fixed, while only the other is driven, thus aligning with one side as a reference. This invention does not specifically limit this, as long as it can position and clamp the frame base.

[0049] The top frame moving assembly 4 includes a translation member 23 and a lifting member 28 coupled to the translation member 23. The top frame moving assembly 4 is configured to move the top frame support positioning assembly 2 to a position directly above the bottom frame positioning assembly 3 and aligned with the frame base. Preferably, the translation member 23 includes two translation supports 24, a translation crossbeam 26 movably coupled between the translation supports 24, two crossbeam drive members 25 disposed on the translation crossbeam 26 and drivenly connected to the translation supports 24, and a crossbeam drive member 27 drivenly connected to the two crossbeam drive members 25. The lifting member 28 includes a lifting drive member and a longitudinal beam coupled to the translation crossbeam 26 that is movable up and down. The lifting drive member is drivenly connected to the longitudinal beam to drive the longitudinal beam to move up and down. The top frame support positioning assembly 2 is coupled to the longitudinal beam.

[0050] Specifically, the top frame moving component 4 moves the top frame support positioning component 2 between the positioning and conveying position of the upper frame and the positioning and fixing position of the frame base at a preset height. In this embodiment, the top frame moving component 4 has only two degrees of freedom in the x-axis and z-axis directions. In other embodiments, the box moving component can be set as a three-degree-of-freedom moving platform, and this invention does not specifically limit it.

[0051] The top frame support positioning assembly 2 includes a top frame positioning base 29 that is engaged with the lifting member 28, a fifth clamping member 33 and a sixth clamping member 32 that are arranged opposite to each other and can slide along a first direction on the top frame positioning base 29, and a seventh clamping member 34 and an eighth clamping member 30 that are arranged opposite to each other and can slide along a second direction on the top frame positioning base 29.

[0052] The fifth clamping member 33 and the sixth clamping member 32 each include: a first clamping seat 45 slidably engaged with the top frame positioning base; a first clamping fixing member 47 and a first telescopic member 52 engaged with the first clamping seat 45; and a first clamping movable member 51 engaged with the output end of the first telescopic member 52. The first clamping fixing member 47 is provided with a fourth clamping surface 49 for clamping the side of the joint portion and a first support surface 48 for supporting the bottom of the flat portion. The fourth clamping surfaces 49 of the fifth clamping member 33 and the sixth clamping member 32 are parallel to each other. The first clamping movable member 51 is configured to press the flat portion onto the first support surface 48.

[0053] The seventh clamping member 34 and the eighth clamping member 30 each include: a second clamping seat 36 slidably engaged with the top frame positioning base; a second clamping fixing member 38 and a second telescopic member 44 engaged with the second clamping seat 36; and a second clamping movable member 43 engaged with the output end of the second telescopic member 44. The second clamping fixing member 38 is provided with a fifth clamping surface 41 and a sixth clamping surface 42 for clamping the side of the joint portion, and a second support surface 40 for supporting the bottom of the flat portion. The fifth clamping surfaces 41 of the seventh clamping member 34 and the eighth clamping member 30 are parallel to each other for clamping the upper frame of the rectangular frame, and the sixth clamping surfaces 42 are inclined to each other for clamping the upper frame of the polygonal frame. The second clamping movable member 43 is configured to press the flat portion onto the second support surface 40.

[0054] Specifically, in the first direction, the upper frame is positioned and clamped by a parallel fourth clamping surface 49. In the second direction, when the upper frame is rectangular, it is clamped and positioned by a parallel fifth clamping surface 41; when the upper frame is a symmetrical polygon, it is clamped and positioned by an inclined sixth clamping surface 42. This adapts to upper frames with different shapes and structures, greatly improving the versatility of the top frame support and positioning component 2. Furthermore, the fourth clamping surface 49, the fifth clamping surface 41, and the sixth clamping surface 42 are designed to be detachable and replaceable, allowing for adaptation to upper frames with more tilt angles by changing the clamping surfaces, thus providing better adaptability.

[0055] In addition, the flat part is pressed onto the first support surface 48 by the first clamping movable part 51, and the flat part is pressed onto the second support surface 40 by the second clamping movable part 43, so as to position the upper frame of the frame in the height direction, further control the distance between the upper frame of the frame and the frame base in the height, so that the assembled frame workpiece is more accurate in size, reduces errors, and provides a good positional basis for fixing the upright plate.

[0056] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, the assembly device further includes a top frame conveying assembly 8 and a top frame flipping assembly 9. The top frame conveying assembly 8 is configured to move the upper frame of the frame to the top frame flipping assembly 9. Specifically, in this embodiment, the upper frame of the frame is conveyed to the assembly device with its flat portion facing down. However, during assembly, the upper frame of the frame needs to be rotated 180 degrees to an angle where its flat portion faces up. Therefore, this embodiment of the invention also includes a device for flipping the upper frame of the frame.

[0057] The top frame flipping assembly 9 includes: a flipping fixed base 63, a conveyor belt 67 and a limiting member 68 disposed on the flipping fixed base 63, a flipping movable base 65 hinged to the flipping fixed base 63, a flipping driving member 64 drivenly connected to the flipping movable base 65, and an electromagnet 66 engaged with the flipping movable base. The limiting member 68 is configured to limit the upper frame of the frame on the conveyor belt 67 and is provided with an avoidance notch 69 for the fifth clamping member 33 to pass through. Specifically, the flipping movable base 65 is provided with a limiting plate to prevent the upper frame of the frame from sliding directly from the flipping movable base 65 onto the conveyor belt 67. In this embodiment, the limiting plate is disposed on one side of the electromagnet 66, so that when the upper frame of the frame abuts against the limiting plate, the flat part is exactly on the electromagnet 66, so that the electromagnet 66 magnetically attracts the flat part.

[0058] Preferably, the top frame conveying assembly 8 includes a multi-axis robot arm, a robot arm connecting seat 53 connected to the multi-axis robot arm, a first conveying base 54 and a second conveying base 62 connected to the robot arm connecting seat 53, a conveying base drive member 61 driven to the second conveying base 62, at least two first clamping drive members 55 connected to the first conveying base 54, a first clamping member 56 and a second clamping member 57 connected to the output end of the first clamping drive member 55, at least two second clamping drive members 60 connected to the second conveying base 62, and a third clamping member 58 and a fourth clamping member 59 connected to the output end of the second clamping drive member 60.

[0059] The transport base drive 61 is configured to drive the second transport base 62 to move closer to or further away from the first transport base 54. The first clamping drive 55 is configured to drive the first clamping member 56 and the second clamping member 57 closer together to clamp onto the joint. The second clamping drive 60 is configured to drive the third clamping member 58 and the fourth clamping member 59 closer together to clamp onto the joint.

[0060] Specifically, the top frame transport assembly 8 is clamped at the joint by a finger cylinder-driven clamping component. Furthermore, the transport base drive component 61 can adjust the distance between the two transport bases to accommodate frame top frames of different sizes.

[0061] Based on the above embodiments, in an optional embodiment of the present invention, such as Figure 8 and Figure 9As shown, the first clamping fixing member 47 is provided with a first clamping groove 50. The first clamping movable member 51 is provided with a first clamping protrusion 46 that matches the clamping groove. The first support surface 48 is provided at the bottom of the first clamping groove 50. The second clamping fixing member 38 is provided with a second clamping groove 39. The second clamping movable member 43 is provided with a second clamping protrusion 37. The second support surface 40 is provided at the bottom of the second clamping groove 39. Specifically, by providing a groove to accommodate the flat part, the movement space of the flat part can be effectively restricted, and the flat part can be accurately positioned.

[0062] Preferably, the top frame support positioning assembly 2 further includes a third positioning and clamping drive member 31 engaged with the fifth clamping member 33 and the sixth clamping member 32, and a fourth positioning and clamping drive member 35 engaged with the seventh clamping member 34 and the eighth clamping member 30. The third positioning and clamping drive member 31 is configured to synchronously drive the fifth clamping member 33 and the sixth clamping member 32 to move closer or further apart. The fourth positioning and clamping drive member 35 is configured to synchronously drive the seventh clamping member 34 and the eighth clamping member 30 to move closer or further apart.

[0063] Specifically, in this embodiment, the fifth clamping member 33 and the sixth clamping member 32 are driven to move closer to each other by the third positioning and clamping driving member 31, and the seventh clamping member 34 and the eighth clamping member 30 are driven to move closer to each other by the fourth positioning and clamping driving member 35, thereby centrally clamping the upper frame of the frame. In other embodiments, one clamping member can be set as fixed, and clamping is performed by driving one side of the clamping member, with the fixed side clamping member as the positioning reference. This invention does not specifically limit this.

[0064] like Figure 1 and Figure 2 As shown, based on the above embodiments, in an optional embodiment of the present invention, the assembly device further includes a first conveying device 5, a second conveying device 6, and a lifting device 7. The first conveying device 5 is used to convey the frame base. The second conveying device 6 is used to convey the upright plate. The lifting device 7 is used to move the frame base and / or the upright plate. Specifically, by conveying the frame base and upright plate through the conveying device, and by using the device therein to lift the frame base and bottom plate, the efficiency of manual assembly and fixing can be greatly improved. In other embodiments, a robotic bag lifting device 7 can be used to achieve automated assembly and fixing; the present invention does not specifically limit this.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
