The cylindrical portion 749 is employed to avoid damage to the wall of the spacing void 230 of the aluminum profile clamp 200. The cylindrical portion 749 may be replaced by a prismatic portion according to practical choices.

The third driving member 740 is connected to the two expanding claws 750, and the third driving member 740 can drive the two expanding claws 750 away from each other to expand the interval space 230 of the aluminum profile clamp 200.

Of course, a screw drive mechanism or a telescopic cylinder or the like may be used instead of the timing belt straight line module.

The clamping robot 700 moves in the left-right direction, and the clamping robot 600 may move in the front-rear direction or the left-right direction.

According to the invention, the feeding frame 300 is arranged to store the orderly aluminum profile clamps 200, the orderly stacked aluminum profile clamps 200 are rotated to the lower part of the clamping manipulator 600 through the rotation of the rotating seat 330, and when the clamping manipulator 600 and the clamping manipulator 700 jointly perform clamping work, the feeding frame 300 is supplemented with the aluminum profile clamps 200, so that the aluminum profile clamping system can continuously clamp a large number of aluminum profiles. The aluminum profile clamp 200 is sent to the expanding claws 750 of the clamping manipulator 700 through the clamping manipulator 600, and the two expanding claws 750 are driven to be far away from each other by the third driving piece 740, so that the acting force of the torsion spring on the aluminum profile clamp 200 is overcome to expand the clamping opening 240 of the aluminum profile clamp 200, time and labor are saved, manual operation is not needed, and the working efficiency is greatly improved.

The support platform 910 is located below the clamping robot 600 for placement of the aluminum profile clamp 200. The support platform 910 may be a metal plate supported by brackets.

A supporting platform 910 is disposed below the clamping robot 600, and is used for the clamping robot 600 to clamp and transfer the aluminum profile clamp 200 to a set position of the supporting platform 910. The clamping manipulator 700 can descend under the operation of the fourth driving member, so that the expanding claw 750 can be inserted into the space gap 230 of the aluminum profile clamp 200 on the supporting platform 910 from top to bottom, and the expanding claw 750 expands the aluminum profile clamp 200 under the driving of the third driving member 740. Then, the clamping manipulator 700 drives the aluminum profile clamp 200 to move to the end of the aluminum profile under the drive of the first driving mechanism.

So designed, the supporting platform 910 serves as a transfer station, so that the clamping manipulator 600 can clamp the aluminum profile clamp 200 and transfer the aluminum profile clamp from the feeding frame 300 to the supporting platform 910 when the clamping manipulator 700 clamps the end part of the aluminum profile conveniently, and the clamping manipulator 700 does not need to wait for resetting, so that the working efficiency is improved. In the present embodiment, the clamping robot 700 moves in the left-right direction, and the clamping robot 600 may move in the front-rear direction or the left-right direction. The cylindrical portion 749 of the clamping robot 700 faces downward.

The bottom of the second mounting seat 580 is provided with the sliding block; the second mounting 580 is bolted to the second driving member. The second mounting seat 580 is connected to the first mounting seat 570 through a metal rod 590, so that the distance between the first mounting seat 570 and the second mounting seat 580 is constant, and the first mounting seat 570 and the second mounting seat 580 can move synchronously.

The second driving device can also be a screw rod type linear module, a telescopic cylinder and the like.

The first driving mechanism with the structure not only realizes the synchronous movement of the clamping manipulator 600 and the clamping manipulator 700, but also can reduce the energy consumption of the first driving mechanism without arranging two driving mechanisms for respectively driving the clamping manipulator 600 and the clamping manipulator 700.

In some embodiments, as shown in fig. 1, 2 and 11, the support platform 910 is provided with a first opening 911, which may be a U-shaped opening. The clamping manipulator 700 is disposed below the supporting platform 910, and the two expanding claws 750 can pass through the first opening 911 from bottom to top and move along the horizontal direction.

Of course, the clamping member 920 may be a metal or plastic member of other shapes. The axial direction of the clamping member 920 is identical to the axial direction of the connection shaft (i.e., Y-axis), and the area of the clamping member 920 that applies pressure to the aluminum profile clamp 200 can be increased, thereby preventing the aluminum profile clamp 200 from rotating horizontally.

The other end (i.e., right end) of the clamping member 920 is provided with a guide portion 921 tilted upward, and the guide portion 921 and the clamping member 920 are integrally formed. The distance between the clamping member 920 and the supporting platform 910 is slightly smaller than the height of the aluminum profile clamp 200, and when the clamping manipulator 600 sends the aluminum profile clamp 200 to the supporting platform 910, the guiding portion 921 plays a better guiding role, so that the aluminum profile clamp 200 smoothly moves to a position between the supporting platform 910 and the clamping member 920.

The rear end of the swing member 930 is connected to the left end of the clamping member 920, and the front end of the swing member 930 is provided with a connection shaft, the axial direction of which is consistent with the moving direction of the clamping robot 700 and the direction (i.e., Y-axis) of the clamping robot 600.

Of course, when the lifting plate 430 approaches the fixture fixing assembly and moves upwards, the first positioning rod 310 or the second positioning rod 320 can pass through the second opening 431 (i.e. the first positioning rod 310 or the second positioning rod 320 is located in the second opening 431), at this time, the rotating seat 330 is provided with a clearance gap between the first positioning rod 310 and the second positioning rod 320, so that the lifting plate 430 can be conveniently moved from below to above the rotating seat 330, and a supporting force is applied to the lowermost aluminum profile fixture 200, so that the aluminum profile fixtures 200 stacked in order are lifted.

Further, a first positioning block 311 is provided at the bottom end of the first positioning rod 310, and the first positioning block 311 is fixed to the first positioning rod 310 by welding or bolts.

By adopting the design, not only can the aluminum profile clamp 200 be stably supported and materials be saved, but also the bottommost aluminum profile clamp 200 can be promoted to be at a certain height from the rotating seat 330, so that the lifting plate 430 can be conveniently and horizontally moved between the rotating seat 330 and the first positioning block 311 or between the rotating seat 330 and the second positioning block 321, and the aluminum profile clamp 200 can be lifted. The first positioning block 311 and the second positioning block 321 may be provided in plurality according to actual needs.

Specifically, the translational drive mechanism includes a motion base 450 and a fifth telescoping cylinder 460.

The moving seat 450 may be a metal plate. The movable seat 450 is provided with a first sliding rail, and the length direction of the first sliding rail is consistent with the X axis.

The lifting plate 430 is driven to move back and forth along the first sliding rail by the telescopic rod of the fifth telescopic cylinder 460, so that the lifting plate 430 is moved more rapidly and work efficiency is improved by approaching to or separating from the fixture fixing assembly.

Of course, the translational driving mechanism may also be an electric push rod, a screw rod transmission mechanism, a linear module, and the like.

In order to prevent the lifting plate 430 from obstructing the rotating seat 330 to drive the clamp fixing assembly to rotate, a translation driving mechanism is arranged to drive the lifting plate 430 to horizontally move; before the rotation of the rotating base 330, the translation driving mechanism drives the lifting plate 430 away from the clamp fixing assembly; after the rotation of the rotating base 330 is completed, the translation driving mechanism drives the lifting plate 430 to approach the fixture fixing assembly so as to lift the aluminum profile fixtures 200 which are stacked in order.
