Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a bed core frame grabbing mechanism. Background Art

[0002] The assembly of a spring bed is generally achieved by automated assembly production. During the assembly process, the frame needs to be put on the edge of the bed core. The frame is generally a rectangular frame structure surrounded by steel wires. When grabbing and transferring the frame, due to the large area of ​​the frame, multiple mechanical clamps are generally required to clamp the frame from multiple positions at the same time, which places high requirements on the grabbing equipment. At the same time, due to the thin steel wire, the frame often falls off during the clamping process. In addition, the frame needs to be put on the bed core after being clamped to complete the assembly, and the frame needs to be stretched out during installation to complete the installation with the bed core, but the traditional clamping device cannot stretch the frame out.

[0003] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present invention and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present invention. Utility Model Content

[0004] In order to overcome the above shortcomings, the purpose of the utility model is to provide a bed core frame grabbing mechanism, thereby effectively solving the above technical problems.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a bed core frame grabbing mechanism, the frame grabbing mechanism comprises:

[0006] An inner support module is used to open the frame from the inside;

[0007] A base, on which the clamping module and the inner supporting module are both installed;

[0008] The robot is connected to the base and drives the base to move.

[0009] The beneficial effects of the utility model are as follows: a bed core frame grabbing mechanism designed in the scheme can clamp the bed core frame and stretch the frame at the same time through the inner support module, thereby ensuring the stability of grabbing, and the stretched frame can be directly put on the bed core.

[0010] Furthermore, it also includes a clamping module for clamping the frame, and the clamping module is installed on the base. The present application uses the clamping module to clamp and fix the frame opened by the inner support module, which is convenient for taking and placing the frame, and can play a fixing effect for the subsequent processing of the frame and the bed core.

[0011] Furthermore, the clamping module includes a clamping claw, a clamping claw cylinder and a telescopic cylinder. The clamping claw cylinder drives the clamping claw to clamp the frame, and the telescopic cylinder drives the clamping claw and the clamping claw cylinder to translate. When the clamping module clamps the frame, the telescopic cylinder first drives the clamping claw to extend and approach the frame, and then the clamping claw cylinder drives the clamping claw to clamp the steel wire part of the frame.

[0012] Furthermore, the clamping module also includes a guide card plate, a card slot is provided at the bottom of the guide card plate, and the guide card plate is arranged parallel to the clamping claw; the function of the guide card plate is to assist the clamping claw in clamping the frame. When the telescopic cylinder drives the clamping claw to extend and approach the frame, the guide card plate and the clamping claw move synchronously, and the steel wire part of the frame enters the card slot of the guide card plate. At this time, the clamping module and the frame complete the initial positioning, so that when the clamping claw is clamping the frame, the frame will not move around, which can effectively ensure that the clamping claw can clamp the frame quickly.

[0013] Furthermore, there are a plurality of clamping modules which are evenly arranged around the edge of the base; the shape of the substrate is the same as that of the frame, both of which are rectangular, and the clamping modules evenly arranged around the substrate can work simultaneously when clamping the frame, ensuring that the frame is clamped out and the clamped frame is in a parallel state with the substrate.

[0014] Furthermore, the clamping module can move toward or away from the frame, thereby enabling the frame to be clamped and making way for subsequent processing of the bed core.

[0015] Furthermore, the inner support module includes a steel wire support plate and a driving cylinder, and the driving cylinder is connected to the steel wire support plate to drive the steel wire support plate to move horizontally; the steel wire support plate can drive the frame to be expanded outward under the action of the driving cylinder, so that the frame remains in an expanded state, so that the frame can be directly put on the bed core without the need to add an additional device for expanding the frame.

[0016] Furthermore, a positioning clamp is provided at the head of the steel wire support plate, and an arc groove is opened on the positioning clamp, and the bending part of the frame can be clamped in the arc groove; the arc groove matches the bending part of the frame, and when the support structure supports the frame, the force point is selected at the bending part of the frame.

[0017] Furthermore, the inner support module is arranged corresponding to the bent corner of the frame, thereby facilitating the effect of expanding the frame.

[0018] Furthermore, there are four inner supporting modules, which are all located at the edge of the base and distributed in a rectangular shape, and the four inner supporting modules correspond to the four bending parts of the frame respectively; the four inner supporting modules distributed in a rectangular shape can just correspond to the four bending parts of the frame, and the four bending parts of the frame can be simultaneously stretched outward, so that the frame can maintain an overall stretched state.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See attached Figures 1 to 4 As shown, an embodiment of the utility model discloses a bed core frame grabbing mechanism, which includes a clamping module 2 for clamping the frame and taking it out from a silo; an inner supporting module 3 for opening the frame from the inner side; a base 4, on which both the clamping module 2 and the inner supporting module 3 are mounted; and a robot 1 connected to the base 4 and drives the base 4 to move.

[0030] The present invention designs a bed core frame grabbing mechanism, which, through the cooperation of the clamping module 2 and the inner supporting module, can clamp the bed core frame and stretch the frame at the same time, thereby ensuring the grabbing stability, and the stretched frame can be directly put on the bed core.

[0031] In some embodiments, the clamping module 2 can move toward or away from the frame. Therefore, when the frame needs to be clamped, the clamping module moves toward the frame, thereby clamping it, and facilitating the subsequent nailing or other processing operations on the frame. When nailing, it is necessary to first avoid the area of ​​the clamping module, then reset the clamping module, and then nail the frame of the original clamping part of the clamping module to the bed core. The movement of the clamping module 1 can be achieved by setting a lifting cylinder or other driving mechanism on the base 4.

[0032] In one or more embodiments, the clamping module 2 includes a clamping jaw 2.1, a clamping jaw cylinder 2.2 and a telescopic cylinder 2.3. The clamping jaw cylinder 2.2 drives the clamping jaw 2.1 to clamp the frame, and the telescopic cylinder 2.3 drives the clamping jaw 2.1 and the clamping jaw cylinder 2.2 to translate.

[0033] When the clamping module 2 clamps the frame, the telescopic cylinder 2.3 first drives the clamping claw 2.1 to extend and approach the frame, and then the clamping claw cylinder 2.2 drives the clamping claw 2.1 to clamp the steel wire part of the frame.

[0034] In one or more embodiments, the clamping module 2 further includes a guide clamping plate 2.4, a clamping slot 2.5 is provided at the bottom of the guide clamping plate 2.4, and the guide clamping plate 2.4 is arranged parallel to the clamping claw 2.1.

[0035] The function of the guide card plate 2.4 is to assist the clamping claw 2.1 in clamping the frame. When the telescopic cylinder 2.3 drives the clamping claw 2.1 to extend and approach the frame, the guide card plate 2.4 moves synchronously with the clamping claw 2.1, and the steel wire part of the frame enters the card slot 2.5 of the guide card plate 2.4. At this time, the clamping module 2 and the frame complete the initial positioning. In this way, when the clamping claw 2.1 is clamping the frame, the frame will not move around, which can effectively ensure that the clamping claw 2.1 can quickly clamp the frame.

[0036] In one or more embodiments, there are a plurality of clamping modules 2 and they are evenly arranged around the edge of the base 4 .

[0037] The shape of the substrate is the same as that of the frame, both of which are rectangular, and the clamping modules 2 evenly arranged around the substrate can work simultaneously when clamping the frame to ensure that the frame is clamped out and the clamped frame is in a parallel state with the substrate.

[0038] In one or more embodiments, the inner support module 3 includes a steel wire support plate 3.1 and a driving cylinder 3.2, and the driving cylinder 3.2 is connected to the steel wire support plate 3.1 to drive the steel wire support plate 3.1 to translate.

[0039] The steel wire support plate 3.1 can drive the frame to be expanded outwards under the action of the driving cylinder 3.2, so that the frame remains expanded, so that the frame can be directly mounted on the bed core without adding a device for expanding the frame.

[0040] In one or more embodiments, a positioning clamp 3.3 is provided at the head of the steel wire support plate 3.1, and a circular arc groove 3.4 is formed on the positioning clamp 3.3, and the bending part of the frame can be clamped in the circular arc groove 3.4.

[0041] The arc groove 3.4 matches the bending part of the frame, and when the expansion structure expands the frame, the force point is selected at the bending part of the frame.

[0042] In one or more embodiments, there are four inner support modules, which are all located at the edge of the base 4 and are distributed in a rectangular shape, and the four inner support modules correspond to the four bending parts of the frame. The four inner support modules distributed in a rectangular shape can correspond to the four bending parts of the frame, and the four bending parts of the frame are simultaneously stretched outward, so that the frame can be kept in an overall stretched state.

[0043] In other possible implementations, the number of the inner supporting modules may be three, five, six, or other numbers, as long as it is ensured that the effect of supporting the frame can be achieved.

[0044] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
