[0002] During the production of aluminum profiles, a robot will pick up the aluminum bars as raw materials and transport them to the processing equipment. In order to save space, most of the aluminum bar raw materials need to be stacked in a material frame. It is difficult for a conventional robot to pick up a single aluminum bar from the material frame without damage.

[0004] However, although the above-mentioned manipulator can clamp the aluminum bar without damage, since the manipulator assembly clamps the aluminum bar at both ends, the method of clamping from both ends has extremely high requirements for site space. When the length of the aluminum bar is too long, the clamping range and movement range required by the manipulator assembly will also increase accordingly. Therefore, there is a need for a clamping manipulator that can clamp the aluminum bar without damage and has a smaller site requirement. Utility Model Content

DETAILED DESCRIPTION

[0032] The present invention is described in detail below in conjunction with specific embodiments.

[0033] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0034] like Figures 1 to 14 As shown, the utility model provides an aluminum bar feeding device, including a bracket body 1, a transport mechanism 2 is arranged on the bracket body 1, the transport mechanism 2 includes a slide 20, a lifting drive 21, a transverse drive 23, a turntable 22, a steering drive 24 and a clamping assembly 3, the slide 20 can slide on the bracket body 1 under the drive of the transverse drive 23, the lifting drive 21 is fixedly installed on the slide 20, a steering drive 24 is installed at the bottom of the lifting drive 21, the steering drive 24 is used to drive the turntable 22 to rotate, and a plurality of groups of clamping assemblies 3 are arranged at the bottom of the turntable 22;

[0035] The clamping assembly 3 includes a clamping bracket 30, a tensioning driving member 31 and a plurality of groups of claws 32. The clamping bracket 30 is installed at the bottom of the turntable 22. The plurality of groups of claws 32 are hinged on the clamping bracket 30. The tensioning driving member 31 is used to drive the claws 32 to move closer to or away from each other.

[0036] The clamping claw 32 includes a clamping portion, on which a vertical surface 320, an insertion inclined surface 321, a clamping protrusion 322 and a clamping arc surface 323 are provided. When clamping, the tensioning driving member 31 controls the clamping claw 32 to make the vertical surface 320 in a vertical state. When the clamping claw 32 probes into the stacked aluminum bars, the insertion inclined surface 321 pushes the aluminum bar to be clamped so that the aluminum bar is centered with the clamping assembly 3. When the clamped aluminum bar enters the clamping range, the tensioning driving member 31 drives the clamping claw 32 to contract so that the aluminum bar is clamped by the clamping protrusion 322 and the clamping arc surface 323.

[0037] Since the diameter of the aluminum rod does not necessarily match the width of the material frame completely, there will be a certain gap between one side of the aluminum rods on the same layer and the side plate of the material frame when stacking, so the aluminum rods on this side can have a certain amount of movement space. The clamping assembly 3 is driven by the transverse driving member 23 to the top of the material frame. Under the action of the detection sensor, the clamping assembly 3 is aligned with the aluminum rod near one end of the gap. Then the lifting driving member 21 drives the clamping assembly 3 to descend. At the same time, the clamping assembly 3 is continuously corrected during the descent process to ensure that the vertical surface 320 of the clamping claw 32 on one side can be aligned with the gap between the two aluminum rods. Since the vertical surface 320 is completely vertical, it will not be affected by the stacked aluminum rods in the same line during the descent process. Under the push of the insertion inclined surface 321, the aluminum rod to be clamped will be pushed away, away from the remaining aluminum rods, and the aluminum rod to be clamped is aligned with the clamping assembly. Then the tensioning driving member 31 controls the clamping claw 32 to clamp the aluminum rod to be clamped. Under the action of the clamping protrusion 323, the clamping claw 32 can prevent the aluminum rod from falling during the clamping process, and the cooperation between the clamping protrusion 323 and the clamping arc surface 323 can clamp the aluminum rod.

[0038] In this embodiment, gears are connected to the transverse driving member 23, the turntable 22 and the steering driving member 24, and a rack is provided on the bracket body 1. Under the mutual cooperation between the gears and the gears, and the gears and the racks, the slide 20 can slide stably on the bracket body 1, and the turntable 22 will also be able to rotate under the drive of the steering driving member 24 when necessary.

[0039] In this embodiment, the support body 1 includes a support leg 10 and a crossbeam 11 . The crossbeam 11 is installed on the support leg 10 . A slide rail 12 is arranged on the crossbeam 11 . A pulley 26 capable of sliding on the slide rail 12 is arranged at the bottom of the slide 20 .

[0040] In this embodiment, the cross section of the slide rail 12 is V-shaped, and the pulley 26 sliding in the V-shaped slide rail 12 can effectively avoid derailment during movement, ensuring that the slide 20 can operate stably.

[0041] In this embodiment, an auxiliary driving member 34 and an auxiliary clamping block 35 are provided on the clamping bracket 30. The auxiliary driving member 34 is used to drive the auxiliary clamping block 35 to rise or fall. A clamping surface is provided at one end of the auxiliary clamping block 35 away from the auxiliary driving member 34, and the clamping surface is in an inverted V shape.

[0042] The clamping claw 32 needs to use a large force to completely restrain the aluminum bar when clamping the aluminum bar, so as to avoid loosening during transportation and causing accidents, but a large force can easily damage the aluminum bar. Through the above design scheme, after the clamping claw 32 clamps the aluminum bar, the auxiliary driving member 34 drives the auxiliary clamping block 35 to descend, so that the clamping surface is against the aluminum bar, and then the clamping claw 32 can fix the aluminum bar through multiple points in different directions to avoid the aluminum bar from loosening during transportation. The inverted V-shaped clamping surface can increase the number of contact points with the aluminum bar, further improving the restriction on the aluminum bar. At the same time, the inverted V-shaped clamping surface can also cope with aluminum bars of different diameters, so as to improve the versatility of the utility model.

[0043] In this embodiment, an auxiliary light rod 25 is provided at the telescopic end of the lifting drive 21, and a linear bearing is installed on the slide 20, in which the auxiliary light rod 25 can slide. The linear bearing and the auxiliary light rod 25 can improve the stability of the lifting drive 21 during movement, ensuring that the clamping assembly 3 can be stably raised or lowered.

[0044] In this embodiment, anti-slip patterns are provided on the clamping protrusion 322 and the clamping arc surface 323 .

[0045] In this embodiment, a slide groove is provided at the part of the clamping claw 32 away from the clamping part, and a swing block 33 is provided in the slide groove, which is hinged to the telescopic end of the tension driving member 31, and the swing block 33 can slide in the slide groove. Through the above design scheme, when the tension driving member 31 extends to both ends, the hinged swing block 33 slides in the slide groove while being extended, driving the clamping parts of the clamping claw 32 to approach each other; when the tension driving member 31 retracts, the swing block 33 drives the clamping claw 32 to rotate, so that the clamping parts are away from each other, and when the tension driving member 31 retracts to the shortest point, the vertical surface 320 is perpendicular to the ground.

[0046] In this embodiment, a detection sensor is provided on the clamping bracket 30 .

[0047] Compared with the prior art, the aluminum bar feeding device provided by the utility model is capable of clamping the stacked aluminum bars. When the stacked aluminum bars are clamped, the vertical surface 320 is aligned with the gap between the aluminum bar to be clamped and the stacked aluminum bar bracket and inserted. The insertion inclined surface 321 pushes the aluminum bar to be clamped into the clamping range of the clamping claw 32. Then, the tensioning driving member 31 drives the clamping claw 32 to approach each other, so as to clamp the aluminum bar at the clamping protrusion 322 and the clamping arc surface 323. At the same time, the auxiliary driving member 34 drives the auxiliary clamping block 35 to press down, and the aluminum bar can be completely clamped in cooperation with the clamping claw 32 for easy transportation.

[0048] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
