Description

Technical Field

[0001] The present invention relates to the field of technical equipment related to the woodworking industry, and more particularly to a device for loading wood boards. Background Art

[0002] At present, during the construction of many intelligent furniture factories, for wood boards that have been subjected to certain surface treatments, due to their smooth surfaces, there is an extremely easy situation of vacuum adhesion between the boards. If the upper board is directly grabbed, it will cause the problem of lifting several layers of the underlying boards, resulting in the inability of automated equipment or robots to accurately pick and place the boards. To solve this problem, most of the existing solutions adopt the form of pushing the boards. However, with the iterative update of new varieties such as new environmentally friendly paints and new process surface treatment methods, the wear resistance of the wood board surfaces varies.

[0003] For processed wood boards, especially for wood boards that have been drilled or milled with patterns on the surface during processing, directly pushing the boards will cause fine scratches on the surface. Manufacturers capable of building intelligent factories in the market are all high-end manufacturers, and consumers and manufacturers are increasingly unable to accept fine scratches. There are mainly two methods for dealing with this problem: One method with relatively low cost is: for products with high surface requirements that cannot use the method of pushing the boards, the original manual online method is adopted. However, this method has a low degree of factory intelligence, high labor costs, and inaccurate positioning after the product is on the line. Another method is: for factories with high requirements for intelligence, directly using robots to suck and place single-layer wood boards into a small three-dimensional board storage library. Although this method has a good degree of intelligence, the production cost has increased significantly. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned existing technologies and provide a wood board loading device that can break the vacuum without damage and has a low cost.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A wood board loading device includes a robot connection plate, a frame connected to the robot connection plate, a vacuum-breaking power mechanism provided at the bottom of the frame, clamping plate mechanisms provided on both sides of the vacuum-breaking power mechanism, and a wood board grabbing mechanism provided at the bottom of the vacuum-breaking power mechanism. The vacuum-breaking power mechanism includes a lifting cylinder provided on the frame, and the lifting cylinder is connected to the wood board grabbing mechanism;

[0007] When grasping stacked wooden boards, the robot presses down the robot connecting plate. The wooden board grasping mechanism first contacts the surface of the wooden board and then continues to press down. After the clamping plate mechanism aligns and clamps the second-layer wooden board, the lifting cylinder contracts, driving the wooden board grasping mechanism to rotate. The surface wooden board rotates around one side of the surface wooden board under the pulling of the wooden board grasping mechanism, allowing air to enter between the surface wooden board and the second-layer wooden board, thus completing the non-destructive vacuum-breaking action of the wooden board.

[0008] Preferably, the vacuum-breaking power mechanism further includes a rotating shaft, a rotating shaft mounting plate, and a rotating plate. The rotating shaft is provided on the robot connecting plate. One end of the rotating plate is connected to the rotating shaft through the rotating shaft mounting plate, and the other end is connected to the lifting cylinder.

[0009] Preferably, the wooden board grasping mechanism includes a suction cup fixing plate and a plurality of suction cups arranged at equal intervals at the bottom of the suction cup fixing plate. The suction cup fixing plate is connected to the rotating plate, and the suction cups are connected to the suction cup fixing plate through buffer rods.

[0010] Preferably, the clamping plate mechanism includes a clamping power source, a moving slider, two clamping block mounting brackets, and clamping blocks provided at the bottom of the clamping block mounting brackets. One clamping block mounting bracket is fixed on one side of the bottom of the machine frame, and the other clamping block mounting bracket is arranged on the other side of the bottom of the machine frame through the moving slider. The moving slider is connected to the clamping power source, and the clamping power source is provided on the machine frame.

[0011] Preferably, a linear slide rail for the moving slider to slide is provided at the bottom of the machine frame.

[0012] Preferably, an adjusting member for adjusting the height of the buffer rod is provided on the machine frame.

[0013] Preferably, the suction cups are vacuum suction cups or sponge suction cups.

[0014] Preferably, the vacuum suction cups are silicone suction cups.

[0015] Preferably, the clamping power source is a power cylinder or a cam.

[0016] Preferably, the adjusting member is a lifting cylinder, and the lifting cylinder is connected to the buffer rod.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] I. Non-destructive vacuum-breaking: In the present invention, the lifting cylinder contracts, driving the rotating plate to rotate. The rotating plate drives the suction cup fixing plate to move, so that the surface wooden board is pulled by the vacuum suction cups, allowing air to enter between the surface wooden board and the second-layer board member, thus completing the non-destructive vacuum-breaking action of the wooden board. Compared with the direct pushing of the board in the prior art, no scratches will be generated on the surface during the vacuum-breaking action, thus ensuring the high quality of the loaded wooden boards.

[0019] II. Cost reduction: The present invention adopts a new vacuum-breaking method, that is, combining the existing grasping mechanism with the vacuum-breaking mechanism, which can effectively complete the two actions of grasping and vacuum-breaking. The structure is compact, reducing the production cost and labor cost;

[0020] III. Wide application range: By adjusting the height of the buffer rod and the type of suction tool, the device of the present invention can not only complete the action of ordinary grasping, but also realize the vacuum-breaking action. It is convenient to use and can be applied to all existing plates;

[0021] IV. Precise product positioning: The clamping plate mechanism of the present invention is an adjustable clamping plate mechanism. By sliding the moving slider to adjust the clamping degree of the clamping block, precise positioning of the product in one direction can be achieved, so as to confirm the horizontal position of the product on the conveyor line, and solve the problem of positioning the product after it is on the production line;

[0022] V. High degree of intelligence: The present invention can cooperate with equipment such as AGV and barcode system to informatize and intelligentize the factory, and achieve the goal of the whole process of product production without landing. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The vacuum-breaking power mechanism includes a lifting cylinder 9, a rotating shaft 7, a rotating shaft mounting plate 4, and a rotating plate 10. The rotating shaft 7 is provided at the bottom of the robot connecting plate 1. One end of the rotating plate 10 is connected to the rotating shaft 7 through the rotating shaft mounting plate 4, and the other end is connected to the lifting cylinder 9.

[0031] The wooden board grasping mechanism includes a suction cup fixing plate 11 and a plurality of vacuum suction cups 3 arranged at equal intervals on the suction cup fixing plate 11. The suction cup fixing plate 11 is connected to the rotating plate 10. A buffer rod 13 for providing buffering is provided on the vacuum suction cup 3, which can be used to ensure the effective completion of the vacuum-breaking action. The buffer rod 13 is connected to the suction cup fixing plate 11, and a lifting cylinder 15 is provided on the suction cup fixing plate 11. The buffer rod 13 is connected to the lifting cylinder 15 to adjust the height at which the vacuum suction cup 3 grasps the wooden board.

[0032] The clamping plate mechanism includes a power cylinder 2, a moving slider 8, two clamping block mounting brackets 5, and two clamping blocks 6. One of the clamping block mounting brackets 5 is fixed at one end of the bottom of the frame 12, and the other clamping block mounting bracket 5 is provided at the other end of the bottom of the frame 12 through the moving slider 8. A linear slide rail 14 matching the moving slider 8 is provided on the frame 12 for the linear movement of the moving slider 8.

Through the action of the moving slider 8, the clamping block 6 can perform grasping and positioning adjustment according to the size of the stacked wooden boards.

[0033] The working principle of the present invention is as follows:

[0034] When grasping a stack of wooden boards, the robot presses down the robot connecting plate 1, driving the entire device to move downward. The vacuum suction cup 3 first contacts the surface of the product, and then the entire wooden board grasping mechanism continues to press down. After the clamping blocks 6 on both sides of the frame 12 are aligned with the second-layer wooden board, the power cylinder 2 contracts, causing the two clamping blocks 6 to clamp the second-layer wooden board. Subsequently, the lifting cylinder 9 contracts, driving the rotating plate 10 to rotate around the rotating shaft 7. The rotating plate 10 drives the suction cup fixing plate 11 to move, so that the surface wooden board rotates with one side of the surface wooden board as the center under the pulling of the vacuum suction cup 3, allowing air to enter between the surface wooden board and the second-layer wooden board, thereby completing the vacuum-breaking action of the wooden board without damage.
