Description

Technical Field

[0002] Engineering robots are similar to handling robots in the logistics industry. Both need to be able to grip and carry regular objects within a certain weight at different heights. Through automation, intelligent logistics can be realized, such as fully automated logistics in scenarios such as ports and logistics centers. However, existing handling robots cannot turn over the box-shaped materials they are carrying. At the same time, the movement direction of the grippers of existing handling robots is fixed, and they can only clamp the box-shaped materials in one direction, that is, they can only clamp the box-shaped materials from top to bottom, or from left to back. They cannot clamp the box-shaped materials in different directions, and are easily restricted by site factors when in use, resulting in the inability to pick up the box-shaped materials. At the same time, the grippers cannot catch materials falling from the air. When grabbing box-shaped materials, the grippers need to open the grippers, and then move the grippers so that the box-shaped materials are located between the two claws of the grippers. Then the grippers can be retracted to grab the box-shaped materials. The grippers move cumbersomely when grabbing box-shaped materials. Summary of the Invention

Since the first synchronous belt fixing part 244 is connected to the lifting synchronous belt 243 on one side of the lifting first transmission wheel 241; the second synchronous belt fixing part 245 is connected to the lifting synchronous belt 243 on the other side of the lifting first transmission wheel 241; when the lifting movable bracket 22 rises, the first synchronous belt fixing part 244 moves downward relative to the lifting first transmission wheel 241, so that the second synchronous belt fixing part 245 moves upward relative to the lifting first transmission wheel 241, and the bracket 121 rises at the same time; when the lifting movable bracket 22 falls, the first synchronous belt fixing part 244 moves upward relative to the lifting first transmission wheel 241, so that the second synchronous belt fixing part 245 moves downward relative to the lifting first transmission wheel 241, and the bracket 121 falls at the same time; the bracket 121 moves on the basis of the movement of the lifting movable bracket 22, and the lifting height amplitude of the bracket 121 is large.

[0071] S3. Determine whether the adsorption member 134 of the gripping device 1313 can contact the side opposite to the box-shaped material. If so, proceed to S4; if not, proceed to S6. In this embodiment, it is manually determined whether the adsorption member 134 can contact the side opposite to the box-shaped material.

[0072] S4. Grab the rotating bracket 133 and drive the adsorption member 134 to rotate away from the avoidance space 1215, so that the adsorption surface of the adsorption member 134 is parallel to the side opposite to the box-shaped material; drive the adsorption member 134 to move to the same horizontal height as the box-shaped material through the lifting device 2; then extend the telescopic movable bracket 112 to make the adsorption member 134 contact with the box-shaped material.

[0073] S5, the adsorption member 134 adsorbs the box-shaped material, and then the telescopic movable bracket 112 retracts; then proceeds to S12.

[0074] S6. If the box-shaped material is above the grabbing device 13, proceed to S7; if the box-shaped material is below the grabbing device 13, proceed to S9.

[0075] S7, the telescopic movable bracket 112 is extended to make the adsorption member 134 located directly below the box-shaped material, and the grabbing rotating bracket 133 is rotated away from the avoidance space 1215 so that the adsorption surface of the adsorption member 134 corresponds to the bottom of the box-shaped material; the lifting device 2 drives the adsorption member 134 to rise and contact the box-shaped material; then proceed to S8.

[0076] S8, the lifting device 2 drives the adsorption member 134 to descend, and then the telescopic movable bracket 112 retracts; then proceeds to S11;

[0077] S9, the telescopic movable bracket 112 is extended to make the adsorption member 134 located directly above the box-shaped material, and the grabbing rotating bracket 133 drives the adsorption member 134 to rotate away from the avoidance space 1215, so that the adsorption surface of the adsorption member 134 corresponds to the top of the box-shaped material; the lifting device drives the adsorption member 134 to descend and contact the box-shaped material; then proceed to S10.

[0078] S10, the lifting device drives the adsorption member 134 to rise, and then the telescopic movable bracket 112 retracts; then proceeds to S11.

[0079] S11, grab the rotating bracket 133 to drive the adsorption component 134 to rotate toward the avoidance space 1215. When the box-shaped material enters the avoidance space, the adsorption component 134 releases the adsorption of the box-shaped material; then grab the rotating bracket 133 and rotate it away from the avoidance space 1215; then proceed to S12.

[0080] S12. The moving device drives the frame to move to the target point; the grabbing rotating bracket 133 drives the adsorption component 134 to rotate toward the avoidance space 1215, and the adsorption component 134 adsorbs the box-shaped material; the adsorption component 134 drives the box-shaped material to rotate away from the avoidance space 1215, and places the box-shaped material on the contact surface of the target point.

[0081] In the above method, the grabbing rotating bracket drives the adsorption element to rotate, so that the adsorption element can contact box-shaped materials at different heights and positions; when there is no obstacle between the adsorption element and the box-shaped material, the adsorption element contacts the opposite side of the box-shaped material, which is highly efficient; when the box-shaped material is located above or below the adsorption element, and there is no obstacle between the adsorption element and the box-shaped material; the height of the adsorption element is changed by the lifting device; so that the adsorption element can contact the opposite side of the box-shaped material at different heights; and the box-shaped materials at different heights can be grabbed.

[0082] When the box-shaped material is located above or below the adsorption component and there is an obstacle between the adsorption component and the box-shaped material, the grabbing and rotating bracket changes the contact position of the adsorption component with the box-shaped material; when the box-shaped material is located above the adsorption component, the adsorption component contacts the bottom of the box-shaped material; when the box-shaped material is located below the adsorption component, the adsorption component contacts the top of the box-shaped material; then the adsorption component and the box-shaped material are driven to move by the lifting device, so that the box-shaped material can be grabbed by crossing the obstacle.

[0083] In the above method,

[0084] S2 also includes: if the box-shaped material is not within the lifting range of the grabbing device 13, then proceed to S13.

[0085] S13: If the box-shaped material is located above the adsorption component, proceed to S14.

[0087] S15, the clamping device holding the box-shaped material above releases its grip on the box-shaped material; the box-shaped material moves closer to the adsorption member under the action of gravity; and then proceeds to S16.

[0088] S16. When the box-shaped material contacts the adsorption member, the support member supports the box-shaped material; under the suction force of the adsorption member, the box-shaped material is adsorbed on the adsorption member; then S8 is performed.

[0089] The above method can grab box-shaped materials dropped from a high altitude; since the box-shaped materials will cause the adsorption part to deform when they hit the adsorption part under the action of gravity, the adsorption part will be unable to adsorb the box-shaped materials; by setting the support part, the rigidity of the adsorption part is improved, and the box-shaped materials are supported by the support part; to prevent the box-shaped materials from hitting the adsorption part under the action of gravity and causing the adsorption part to deform.
