Abstract
Description
Technical Field
[0001] This utility model relates to a loading and unloading robot, specifically, to a single-unit valve control fixture, a bottom-supporting fixture, and a loading and unloading robot. Background Technology
[0002] A loading and unloading robot is an intelligent device equipped with sensors, lenses, and electro-optical systems that can quickly sort and move goods.
[0003] More and more visual sensors and force sensors will be used in loading and unloading robots, making them increasingly intelligent. With advancements in sensing and recognition systems, artificial intelligence, and other technologies, robots are evolving from being controlled unidirectionally to storing and applying their own data, gradually becoming information-based.
[0004] When sorting and handling goods using loading and unloading robots, visual sensors are needed to capture images of the goods. The posture of the goods is determined by recognizing the images of the goods, and then the loading and unloading robot picks or handles the goods using the loaded grippers or suction cups.
[0005] When loading and unloading robots disassemble goods from containers with frames, tops, and partitions, such as boxes, shelves, and cages, they need to grip one side of the goods. However, when the size of the goods is smaller than the size of the gripper, it often sucks up two adjacent goods. This not only requires replacing the gripper with one of the wrong size, but also often causes adjacent goods to be accidentally pulled off. Utility Model Content

[0127] In this embodiment of the utility model, the single valve control fixture 2 includes multiple suction cup areas arranged adjacent to each other;
[0128] Each of the suction cup areas is used to provide suction individually for side suction of a target box of one size and to provide suction, in whole or in part, simultaneously for side suction of a target box of another size.
[0129] That is, by controlling the clamp 2 with a single valve in a zone, it is possible to pick up the side of a target box with a small area. In other words, each suction cup area is controlled separately to pick up the side of a target box of a certain area, avoiding pulling on the adjacent target boxes. At this time, the suction cup area is smaller than the area of the surface of the target box to be picked up.
[0130] In one embodiment of this utility model, the plurality of suction cup areas have the same height, but the width of the plurality of suction cup areas is smaller than that of the single valve control clamp 2, so it can be used to pick up target boxes whose width is smaller than that of the plurality of suction cup areas.
[0131] In one embodiment of this utility model, since each suction cup can be individually controlled by the solenoid valve 203, any one or more of the plurality of suction cup areas can be controlled to perform vacuum suction simultaneously.
[0132] In summary, the choice between the single valve control fixture 2 and any one or more of the suction cup areas depends on the area of the suction side of the target box. Generally, the suction cup area needs to be located inside the suction side and be able to provide sufficient suction to lift the target box.
[0133] In a variation of this utility model, the bottom support clamp 100 provided by this utility model includes:
[0134] Fixture body 1;
[0135] The suction cup bracket 208 is provided with the single valve control clamp 2, which is used to pick up the target box. The suction cup bracket 208 is provided on the clamp body 1 and can move along the first direction.
[0136] The bottom support mechanism 3 is located on the clamp body 1 and can move in a second direction opposite to the first direction;
[0137] The first driving unit is used to drive the suction cup bracket 208 to move along the guide mechanism;
[0138] The second driving unit is used to drive the bottom support mechanism 3 to move along the bottom support guide mechanism 6, wherein the suction cup bracket 208 and the bottom support mechanism 3 move in opposite directions.
[0139] In this modified example, the suction cup bracket 208 and the bottom support mechanism 3 are driven by different drive units. The suction cup bracket 208 and the bottom support mechanism 3 can be controlled by the controller to move in opposite directions at the same time, or the suction cup bracket 208 can be controlled to move several seconds before the bottom support mechanism 3, or the suction cup bracket 208 can be controlled to move several seconds after the bottom support mechanism 3. The number of seconds can be any number of seconds from 1 to 3 seconds, such as two seconds.

[0144] Step S1: Control the suction cup bracket 208 to move to the front end of the clamp body 1 to pick up one side of the target box;
[0145] Step S2: Control the drive module 4 to drive the suction cup bracket 208 to move from the front end of the clamp body 1 to the rear end of the clamp body 1, while the bottom support mechanism 3 extends from the front end of the clamp body 1 to support the target box.
[0146] Step S3: Control the drive module 4 to drive the suction cup bracket 208 to move from the rear end of the clamp body 1 to the front end of the clamp body 1 to push out the target box, while the bottom support mechanism 3 retracts into the clamp body 1.
[0147] More specifically, it includes the following steps:
[0148] Obtain a stack image of the box stack, identify the stack image, and determine multiple target box areas on the stack image;
[0149] Multiple target boxes to be extracted are determined based on the positions of the multiple target box areas, and then the length and height of the target boxes are determined;
[0150] When the height of the side to be sucked is greater than the height of the individual valve control clamp and the length of the side to be sucked is greater than the length of the individual valve control clamp, the target box is sucked up by the individual valve control clamp.
[0151] When the height of the side to be sucked is greater than the height of the individual valve control fixture and the length of the side to be sucked is less than the length of the individual valve control fixture, the target box is sucked up through a suction cup area of the individual valve control fixture.
[0152] In this embodiment of the invention, each suction cup can be individually controlled by a solenoid valve, thus making it suitable for target boxes with different side areas. Multiple suction cups providing vacuum can be determined based on the length and width of the target box's side, thereby avoiding suction of adjacent target boxes. The clamp body is equipped with a clamp guide mechanism and a bottom support guide mechanism extending along its length. The suction cup bracket is connected to the clamp guide mechanism and can slide along it. The bottom support mechanism is connected to the bottom support guide mechanism and can slide along it. When the suction cup array on the suction cup bracket picks up the target box, the drive module drives the suction cup bracket to move towards the rear end of the clamp body to grip the target box. Simultaneously, the drive module drives the bottom support mechanism to extend from the front end of the clamp body to support the target box, thereby enabling loading, unloading, and destacking of boxes in confined spaces such as shipping containers.
