Description

Technical Field

[0001] The utility model relates to the technical field of taking and placing wooden boards, in particular to a taking and placing device for preventing thin wooden boards from deforming. Background Art

[0002] In the process of wood board processing, using vacuum suction cups for picking up and transporting is an efficient, safe and automated solution. This method is particularly suitable for processing large-sized, moderately heavy and flat wood board materials. The vacuum suction cup uses a vacuum pump to generate negative pressure to extract air from the inside of the suction cup, thereby forming a vacuum area between the suction cup and the adsorbed object (such as a wood board). Due to the effect of atmospheric pressure, the wood board is tightly adsorbed on the suction cup to achieve stable grasping. When the wood board needs to be released, air is introduced into the suction cup by controlling the valve to break the vacuum state, and the wood board can be easily removed. However, when using a vacuum suction cup to pick up and transport thin wood boards, due to the thin thickness of the thin wood board and the effect of its own gravity, the edges and corners of the thin wood board are prone to drooping and deformation, which will reduce the quality of the wood board. In severe cases, it will cause the thin wood board to be processed, so the defective rate of the wood board processing will be high, which will also increase the processing cost of the wood board. Therefore, a pick-up and placement device that prevents the deformation of thin wood boards is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a pick-and-place device for preventing thin wood board from being deformed comprises a main pick-and-place mechanism 1, which is composed of a main mounting bracket 4, a sub-mounting bracket 5 and a vacuum suction cup 6. There are several sub-mounting brackets 5 and they are evenly fixedly mounted on the lower end of the main mounting bracket 4. There are several vacuum suction cups 6 and they are symmetrically fixedly mounted on several sub-mounting brackets 5 in pairs. A thin wood board body 3 is adsorbed on several vacuum suction cups 6. Both ends of several sub-mounting brackets 5 are provided with a mounting slot 7. Two sub-picking and placing mechanisms 2 are symmetrically mounted on the main pick-and-place mechanism 1. The sub-picking and placing mechanisms 2 are composed of a first driving cylinder 8, a connecting structure 9, a movable substrate 10, and a second driving cylinder 8. The main pick-and-place mechanism 1 is composed of a cylinder 11, a rectangular frame 12 and a supporting rubber pad 13. The connecting structure 9 is fixedly mounted on the telescopic rod of the first driving cylinder 8, the movable base plate 10 is fixedly mounted on the outer end of the connecting structure 9, the second driving cylinder 11 is fixedly mounted on the upper end of the movable base plate 10, the rectangular frame 12 is fixedly mounted on the telescopic rod of the second driving cylinder 11, and the supporting rubber pad 13 is fixedly mounted on the bottom wall of the rectangular frame 12. When in use, the main pick-and-place mechanism 1 can be installed and fixed on the three-axis truss manipulator. When picking up and transporting the veneer board body 3, the three-axis truss manipulator can move the main pick-and-place mechanism 1 close to the veneer board body 3 until the vacuum suction cup 6 and the veneer board body are finally connected. The main pick-and-place mechanism 1 is in contact with the board body 3, and at the same time, the vacuum pump generates negative pressure to extract the air from the inside of the suction cup, so that the thin board body 3 is adsorbed on the vacuum suction cup 6, and then the three-axis truss manipulator can move the main pick-and-place mechanism 1 upward, at this time, the thin board body 3 will be grabbed, and then the first driving cylinder 8 on the auxiliary pick-and-place mechanism 2 can be started, so as to push the movable substrate 10 outward through the connecting structure 9, and then the second driving cylinder 11 is started to push the rectangular frame 12 downward, and finally the movable substrate 10 is moved inward by the first driving cylinder 8, and finally the rectangular frame 12 is sleeved on the corners of the thin board body 3, and the corners of the thin board body 3 will be in contact with the board body 3. The supporting rubber pad 13 is in contact, so that the rectangular frame 12 and the supporting rubber pad 13 will support the corners of the veneer board body 3, thereby preventing the corners of the veneer board body 3 from being in a drooping state for a long time during the process of being picked up and transported, thereby reducing the probability of deformation at the corners of the veneer board body 3, and ultimately reducing the defective rate of the wood board processing, thereby reducing the processing cost of the wood board; when the veneer board body 3 needs to be put down, the first driving cylinder 8 and the second driving cylinder 11 can be used to move the rectangular frame 12 to the top of the veneer board body 3, and then air is introduced into the vacuum suction cup 6, and then the veneer board body 3 will fall off.

[0020] Furthermore, the first driving cylinder 8 on the auxiliary picking and placing mechanism 2 is fixedly mounted on one end of the main mounting bracket 4, and the movable base plate 10 on the auxiliary picking and placing mechanism 2 is movably mounted in the mounting slots 7 opened on several auxiliary mounting brackets 5.

The rectangular frame 12 is located below the movable base plate 10. The telescopic rod of the first driving cylinder 8 can push the movable base plate 10 to slide in the mounting slot 7. When the movable base plate 10 moves, it will drive the second driving cylinder 11 thereon to move together, and the telescopic rod of the second driving cylinder 11 can push the rectangular frame 12 to move up and down.
