Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, and particularly relates to a vacuum adsorption device. Background Art

[0002] A vacuum adsorption device is a device that uses the suction force generated by a vacuum to grasp and transport objects. Such a device is usually used on an automated production line and is very common in industries such as electronics, packaging, and printing. It can stably adsorb and move various shaped and textured items, especially items with a smooth or fragile surface. However, most current vacuum adsorption devices can only transport one piece of material at a time. Especially for strip-shaped materials, due to the long length and short width of the materials, higher requirements are placed on the layout structure of the suction cups. At the same time, if the suction cup layout is fixed, it cannot meet the handling requirements of materials of different sizes. Content of the Utility Model

[0003] The purpose of the utility model is to solve the technical problems existing in the prior art, and provide a vacuum adsorption device that can adsorb multiple strip-shaped materials at one time and meet the requirements of different material sizes at the same time.

It should be understood that the specific implementation manners described here are only used to explain the present utility model and do not limit the protection scope of the present utility model.

[0019] It should be noted that when an element is referred to as "fixed to", "arranged on", "secured to" or "mounted on" another element, it can be directly on the other element or there may be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. Further, when an element is considered to be "fixedly connected" to another element, the two can be fixed in a detachable connection manner or a non-detachable connection manner, such as socket connection, snap connection, integral molding fixation, welding, etc., which can be achieved in the prior art and will not be elaborated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is perpendicular, but due to the influence of manufacturing and assembly, there may be a certain perpendicular error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation mode.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are only for the purpose of describing specific implementation modes and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] The "first" and "second" involved in this utility model do not represent specific quantities and sequences, and are only used for name distinction.

[0022] A vacuum adsorption device includes a vacuum gripper and a vacuum generator. The vacuum gripper includes a suction cup mounting part. The suction cup mounting part includes a strip-shaped mounting part 101 arranged side by side. A plurality of suction cups 102 matching the strip-shaped mounting part are mounted on each strip-shaped mounting part 101. It also includes a connection between the output end of the vacuum generator and the suction cups 102.

[0023] It further includes a variable pitch fixture. The variable pitch fixture includes a mounting frame 201, a fixture mounting block 202 and a variable pitch cylinder 203. The number of fixture mounting blocks 202 is the same as the number of strip-shaped mounting parts 101. Each fixture mounting block 202 is fixedly connected to each strip-shaped mounting part 101 in a one-to-one correspondence. All fixture mounting blocks 202 are sequentially movably connected by a fixture connecting piece 204 to form an integral mounting block 210. One end of the integral mounting block 210 is fixed to the mounting frame 201, and the other end is connected to the output end 205 of the variable pitch cylinder. The movement of the output end 205 of the variable pitch cylinder drives the integral mounting block 210 to open / close (or expand / contract). Figure 1 It is a vacuum adsorption device that adsorbs strip-shaped materials.

[0024] Specifically, preferably, the fixture connecting piece 204 at one end of the overall mounting block 210 is fixed to the mounting frame 201, and the fixing connecting piece 211 is fixed to the fixture mounting block at the other end of the overall mounting block 210. The connecting piece 211 is fixedly connected to the output end 205 of the variable pitch cylinder. As shown in the figure, it is preferably an L-shaped connecting piece.

[0025] As a preferred solution, in order to make the structure of the overall mounting block 210 more stable, through holes are provided at both ends of each fixture mounting block 202, and movable guide rods 212 are arranged in the through holes. During the opening / closing process of the overall mounting block, the movable guide rods 212 make the overall mounting block tend to be stable. Preferably, a hollow connecting shaft is installed in the through hole, and the movable guide rod passes through the hollow connecting shaft. Considering that the manufacturing process of the fixture mounting block cannot make the through hole of the fixture mounting block smooth enough, the setting of the hollow connecting shaft can make the movable guide rod move more smoothly relative to each other.

[0026] As a preference, as shown in the figure, the fixture connecting piece 204 includes a movable channel 206 and a first fixed end 207. A slider 208 is provided on one side of each fixture mounting block, and a second fixed end 209 is on the other side. The slider 208 on one side of the fixture mounting block is close to the second fixed end 209 of the adjacent fixture mounting block. The first fixed end 207 and the second fixed end 209 of the fixture connecting piece 204 are connected. The slider of the fixture connecting piece 208 is movably installed in the movable channel. In this way, when the output end of the variable pitch cylinder is displaced, the adjacent fixture mounting blocks will be displaced along with the displacement of the cylinder output end, so as to realize the opening / closing movement of the overall mounting block. However, the opening / closing movement will be restricted within a certain range by the fixture connecting piece. The length of the movable channel of the fixture connecting piece determines the telescopic range of the overall mounting block.

[0027] Exemplarily, the fixture connecting piece is implemented as the convex structure in the figure.

[0028] It further includes a connecting part 100 for connecting to one end of an external robotic arm. Generally, the vacuum adsorption device needs to be connected to the robotic arm of the intelligent robot to enable the overall vacuum adsorption device to perform actions such as rotation and displacement.

[0029] Operating principle: The intelligent robot controls the vacuum adsorption device to grab materials from the bin and transport them to the preset end position.

[0030] Among them, the intelligent robot, exemplarily such as a six-axis multi-joint robot, can realize the automatic material transportation by burning the self-developed program according to the performance of the robot. Regarding the specific mechanism and software control content of the robot, they are not described in this embodiment.
