Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention for bending machines, in particular to an automatic dust prevention device for a gripper library of a bending robot. Background Art

[0002] At present, in industrial production, industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices for the industrial field, which can perform work automatically. The executive component of the industrial robot is the gripper, so the structure and flexibility of the gripper are crucial. The current grippers are all equipped with a single positioning fixture on the driving end of the finger cylinder or use multiple sets of cylinders to install the positioning fixture to achieve the function of the gripper. In order to save the time of changing the gripper, a robot gripper frame is usually equipped next to the robot to facilitate the robot to automatically change the gripper.

[0003] However, there is currently no dust-proof mechanism on the quick-change plate on the gripper, and dust is easily deposited on the surface and inside when it is exposed to the outside for a long time, which leads to poor contact after assembly and affects the control signal. Utility Model Content

[0004] The technical problem to be solved by the utility model is that: currently there is no dustproof mechanism on the quick-change disc on the clamping claw, and dust is easily collected on the surface and inside when the disc is exposed to the outside for a long time, thereby causing poor contact after assembly and affecting the control signal.

[0017] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" 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 a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] Figure 1 and Figure 2The automatic dust prevention device for the gripper library of the bending robot shown includes a gripper frame main body, which includes a horizontal bottom frame 1, lateral columns 2 welded and fixed on both sides of the upper end of the horizontal bottom frame 1, an inclined support frame 3, a first beam 4 fixed on the inclined support frame 3, and a second beam 5 fixed on the inclined support frame 3. First grippers 7 are installed on both sides of the first beam 4 through a first lateral assembly frame 6, and a second gripper 9 is installed on one side of the second beam 5 through a second lateral assembly frame 8. A first electrically-controlled dust prevention mechanism 10 is installed above the first beam 4 corresponding to the first gripper 7, and a second electrically-controlled dust prevention mechanism 11 is installed above the second lateral assembly frame 8 corresponding to the second gripper 9.

[0020] The first gripper 7 and the second gripper 9 are both prior art, and the robot in the prior art is programmed to automatically change the gripper, and the quick-change plate is matched and installed with the manipulator.

[0021] In order to cooperate with the closed sealing of the quick-change disk on the first gripper 7, the first electrically controlled dust-proof mechanism 10 includes a first cylinder assembly 101 movably mounted on the top of the lateral column 2, a first dust-proof diagonal brace 102 movably mounted on the side wall of the first crossbeam 4, and a first accordion cover 103 fixed on the non-movable connection end of the first dust-proof diagonal brace 102.

[0022] In order to cooperate with the closed sealing of the quick-change disk on the second gripper 9, the second electrically controlled dust-proof mechanism 11 includes a second cylinder assembly 111 movably mounted on the upper end of the second lateral assembly frame 8, a second dust-proof diagonal brace 112 movably mounted on the side wall of the second lateral assembly frame 8, and a second accordion cover 113 fixed on the non-movable connection end of the second dust-proof diagonal brace 112.

[0023] The first cylinder assembly 101 and the second cylinder assembly 111 are both prior art. The first cylinder assembly 101 controls the first dustproof diagonal brace 102 to flip and adjust by telescoping, and the second cylinder assembly 111 controls the second dustproof diagonal brace 112 to flip and adjust by telescoping.

[0024] In order to facilitate the installation and fixation of the second gripper 9, a bushing mounting plate 12 for mounting the second gripper 9 is symmetrically fixed on the inner side of the second lateral assembly frame 8. The second gripper 9 is fixedly assembled with the bushing mounting plate 12 by positioning pins on both sides.

[0025] In order to cooperate with the movable assembly of the first cylinder assembly 101 , a cylinder fixing piece 13 is bolted to the top end of the lateral column 2 .

[0026] In order to facilitate assembly, the first cross beam 4 and the second cross beam 5 are horizontally arranged on the inclined support frame 3 .

[0027] The main body of the gripper frame is triangular in shape as a whole and has a strong supporting effect. The square tube fixation makes the structure simpler. Each first cylinder assembly 101 and the second cylinder assembly 111 are installed with two sensors. When the robot gripper moves in front of the first gripper 7 and the second gripper 9, the sensor gives a signal to control the first cylinder assembly 101 and the second cylinder assembly 111 at the corresponding position to contract and drive the first electrically controlled dustproof mechanism 10 or the second lateral assembly frame 8 to move. The first electrically controlled dustproof mechanism 10 and the second electrically controlled dustproof mechanism 11 are lifted up, and the robot changes the gripper. When the robot leaves the detection position, the sensor gives a signal, and the first electrically controlled dustproof mechanism 10 and the second electrically controlled dustproof mechanism 11 move downward to cover the outer side of the quick-change disk of the first gripper 7 and the second gripper 9 to play a dustproof role.

[0028] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
