Description

Technical Field

[0001] The utility model relates to the technical field of single board processing, in particular to a single board repairing device. Background Art

[0002] Wood is a natural and environmentally friendly high-quality raw material. With the continuous development of social economy in recent years, the demand for wood in various industries has further increased. However, in the face of increasingly stringent log export controls and the implementation of natural forest protection policies in wood exporting countries, my country's wood resource shortage problem is becoming increasingly serious, and the contradiction between wood supply and demand and structure is becoming increasingly prominent.

[0003] In order to make more effective use of limited wood resources, wood veneer processing has become an efficient way of utilization. By processing wood into veneers, each piece of wood can be maximized, waste can be reduced, and the efficiency of wood use can be improved. This processing method can produce a variety of products, such as ordinary plywood, blockboard, veneer laminated lumber, etc. These products are widely used in construction, furniture, decoration and other fields.

[0004] As an indispensable basic unit in the modern wood processing industry, the quality of veneer is directly related to the overall performance and market competitiveness of the final board product. However, in the production process of veneer, due to the influence of various factors such as the unevenness of raw materials, mechanical damage during processing, and environmental factors such as changes in humidity and temperature, defects such as dead knots, live knots, cracks, and voids often appear on the surface of the veneer. These defects not only reduce the appearance quality of the veneer, but also affect its mechanical properties and durability, bringing many inconveniences to the subsequent processing and use of the board.

[0005] Traditional methods of repairing defects in veneers mostly rely on manual or semi-automatic equipment, which is inefficient and difficult to guarantee quality. For example, a common method is to manually identify veneer defects, then transfer the defective veneer to a hot press, and then place wood chips at the defects. The hot press welding head of the hot press heats and presses the wood chips to repair the defects. This method has a low degree of automation, high labor intensity, low manual operation efficiency, and difficult to guarantee quality, which has a great impact on the quantity and quality of veneer manufacturing.

[0044] Please refer to Figures 1 to 4 The preferred embodiment of the utility model provides a veneer repair device, which mainly includes a conveyor 10, a feeding mechanism 20, a visual recognition device 30, a wood chip placement table 40, a first robotic arm 50, a second robotic arm 60, a hot press 70 and a controller.

[0045] The conveyor 10 is used to transmit a single board. The conveyor 10 adopts a belt conveyor, which includes a conveyor frame 13, a conveying belt 14, a driving wheel, a passive wheel, a second motor 15 and a transmission belt. The driving wheel and the passive wheel are rotatably mounted at both ends of the conveyor frame 13 respectively, and the conveying belt 14 is sleeved on the driving wheel and the passive wheel. The second motor 15 is fixedly mounted on the conveyor frame 13. A driving wheel is fixedly mounted on the output shaft of the second motor 15, and a transmission wheel is coaxially arranged on the driving wheel. The driving wheel and the transmission wheel are sleeved with a transmission belt, so that when the second motor 15 is running, the driving wheel drives the transmission belt to drive the transmission wheel, and drives the driving wheel to rotate, so that the conveying belt 14 can be driven to operate, so as to realize the transmission of the single board placed on the conveying belt 14. The transmission direction of the single board on the conveying belt 14 is from the front end of the conveying belt 14 to the end of the conveying belt 14. At the same time, in the exemplary embodiment of the utility model, the transmission direction of the conveying belt 14 is defined as the longitudinal direction.

[0046] The loading mechanism 20 is disposed at the front end of the conveyor 10 and is used to transport the single boards piece by piece to the conveyor 10. The single boards are loaded in a single piece, that is, the single boards are transported piece by piece to the conveyor 10. At this time, the single boards are transported sequentially by the conveyor 10. In some embodiments, Figure 5 As shown, the single boards 80 are stacked near the front end of the conveyor 10 . In some embodiments, the single boards can be transported to the front end of the conveyor 10 by an AGV.

[0047] The visual recognition device 30 is arranged above the conveyor 10, and is used to visually recognize the single board transmitted by the conveyor 10, so as to mark the position of the single board where the defect is located when the single board being recognized has a defect. The visual recognition device 30 uses a visual recognition system or device of the prior art, such as a visual recognition system or device that uses a CCD camera as a visual detection and forms a signal, which is a mature prior art and will not be explained in detail here. The utility model uses the visual recognition device 30 to visually recognize the single board passing through the visual recognition device 30, so as to mark the position of the single board where the defect is located when the single board being recognized has a defect.

[0048] The wood chip placement platform 40 is located beside the conveyor 10 and is used to place wood chips for repairing defects of the veneer. The wood chips are flaky structures, and the material of the wood chips is preferably consistent with the material of the veneer.

[0049] The first robot arm 50 is located next to the conveyor 10 and is used to place the wood chips on the wood chip placement table 40 at the defective position of the veneer. The second robot arm 60 is located next to the conveyor 10, and a hot press 70 is arranged on it. The hot press 70 is driven by the second robot arm 60 and hot presses the wood chips placed at the defective position of the veneer. The hot press 70 has a hot press welding head 71, which has a certain temperature. In this exemplary embodiment, the temperature of the hot press welding head 71 is preferably 130-150°C. At this temperature, it can cooperate with the pressure applied by the second robot arm 60 to realize hot pressing of the wood chips at the defective position of the veneer without burning the wood chips or the veneer. In this exemplary embodiment, the second robot arm 60 drives the hot press welding head 71 vertically downward to realize hot pressing, and the first robot arm 50 and the second robot arm 60 use robot arms of the prior art.

[0050] The controller is electrically connected to the visual recognition device 30, the first robot arm 50 and the second robot arm 60 to receive the detection signal of the visual recognition device 30 and control the first robot arm 50 to place the wood chips on the wood chip placement table 40 at the defective position of the single board according to the detection signal, and control the second robot arm 60 to drive the hot press 70 to hot press the wood chips placed at the defective position of the single board. Through the controller, electrical connection with other components and automatic control are achieved to realize the automation of single board repair. The controller preferably adopts an industrial computer. In a preferred embodiment, the controller can also be electrically connected to the conveyor 10 and the feeding mechanism 20 to control the start and stop or conveying speed of the conveyor 10, and control the feeding of the feeding mechanism 20, such as controlling the feeding speed.

[0051] During implementation, the feeding mechanism 20 sequentially transports the veneers to the conveyor 10 one by one. The veneers are transmitted on the conveyor 10 and pass under the visual recognition device 30. The visual recognition device 30 detects whether there are defects. If there are defects, the position of the veneer is marked with the defect and the signal is transmitted to the controller. The veneer continues to be conveyed by the conveyor 10. When the veneer has defects, the controller controls the first mechanical arm 50 to place the wood chips on the wood chip placement table 40 at the defective position of the veneer, and when the veneer passes through the second mechanical arm 60, the controller controls the second mechanical arm 60 to drive the hot press 70 and use the hot press 70 to hot press the wood chips placed at the defective position of the veneer, thereby realizing the hot pressing repair of the veneer defects. The veneer repair device of the utility model can realize the hot pressing repair of veneer defects, and the repair has a high degree of automation, high operating efficiency, and high repair quality. It can improve production efficiency, reduce errors caused by human factors, and improve product quality. It is of great significance to improve wood production efficiency, reduce labor costs, improve product quality, and promote technological innovation.

[0052] In a preferred embodiment, the feeding mechanism 20 includes a longitudinal drive mechanism, a vertical drive mechanism and an adsorption mechanism. The longitudinal drive mechanism can realize longitudinal movement, and the longitudinal movement direction of the longitudinal drive mechanism is toward or away from the conveyor 10; the vertical drive mechanism can realize vertical drive, and the vertical drive mechanism is installed on the longitudinal drive mechanism and driven by the longitudinal drive mechanism to move longitudinally; the adsorption mechanism is installed on the vertical drive mechanism for adsorbing single boards.

[0053] The longitudinal drive mechanism includes a support frame 21, a longitudinal guide rail 22, a longitudinal guide block 23, a first motor 24, a rack 25 and a gear 26. The longitudinal guide rail 22 is fixedly mounted on the support frame 21, the longitudinal guide rail 22 extends longitudinally, the longitudinal guide block 23 is slidably mounted on the longitudinal guide rail 22, and the longitudinal guide block 23 is fixedly connected to the vertical drive mechanism; the rack 25 is fixedly mounted on the support frame 21, and the extension direction of the rack 25 is consistent with the extension direction of the longitudinal guide rail 22; the first motor 24 is fixedly connected to the longitudinal guide block 23, the gear 26 is fixedly mounted on the output shaft of the first motor 24, and the gear 26 is meshed with the rack 25. During implementation, the first motor 24 starts the driving gear 26 to rotate. Since the gear 26 is meshed with the rack 25, the first motor 24 is subjected to force and can drive the longitudinal guide block 23 to slide on the longitudinal guide rail 22. The sliding direction is longitudinal. At this time, the vertical driving mechanism installed on the longitudinal guide block 23 moves longitudinally together, and the vertical driving mechanism can move to the top of the conveyor 10.

[0054] The vertical driving mechanism includes a vertical guide rail 28, a vertical slider 29 and a cylinder 210. The vertical guide rail 28 is fixedly mounted on the longitudinal guide block 23. In the preferred embodiment, the vertical guide rail 28 is mounted on the longitudinal guide block 23 through a connecting arm 27, and the vertical guide rail 28 extends vertically; the vertical slider 29 is slidably mounted on the vertical guide rail 28, and the cylinder 210 is fixedly mounted on the vertical guide rail 28, and the telescopic shaft of the cylinder 210 is fixedly connected to the vertical slider 29. During implementation, when the telescopic shaft of the cylinder 210 is extended, it can drive the vertical slider 29 to move vertically downward, and when the telescopic shaft of the cylinder 210 is retracted, it can drive the vertical slider 29 to move vertically upward. At this time, through the vertical up and down movement, the adsorption mechanism installed in the vertical driving mechanism is driven to move vertically.

[0055] Preferably, a receiving hole is provided at the bottom of the vertical slider 29, and a telescopic rod 213 is inserted into the receiving hole. A spring 214 is sleeved on the telescopic rod 213, and one end of the spring 214 is connected to the vertical slider 29, and the other end is connected to the lower end of the telescopic rod 213. The adsorption mechanism is installed on the lower end of the telescopic rod 213. By providing the telescopic rod 213 and the spring 214, it is possible to achieve that when the telescopic rod 213 is compressed, it can retract into the receiving hole at the bottom of the vertical slider 29, and when the pressure is released, it can be reset and extended under the reset action of the spring 214. In this way, flexible contact between the adsorption mechanism and the single board can be achieved, and damage to the single board or the feeding mechanism 20 in a rigid contact manner can be avoided.

[0056] The adsorption mechanism includes an adsorption frame 211 and a first vacuum suction cup 212. The adsorption frame 211 is fixedly mounted on the vertical driving mechanism and driven to move vertically by the vertical driving mechanism. Specifically, in the preferred embodiment, the adsorption frame 211 is mounted on the lower end of the telescopic rod 213, and the vacuum suction cup 212 is fixedly mounted on the adsorption frame 211. There are four vacuum suction cups 212, which are located at the four corners of the adsorption frame 211. The vacuum suction cup 212 is equipped with a vacuum generator, a solenoid valve, and a hose (not shown in the figure) to achieve negative pressure adsorption, so that the single board can be sucked up. When it is adsorbed to a certain position, such as above the conveyor 10, the negative pressure is released, and the single board can fall from the vacuum suction cup 212 to the conveyor 10 to achieve loading.

[0057] During implementation, the first motor 24 starts the driving gear 26 to rotate, driving the longitudinal guide block 23 to slide on the longitudinal guide rail 22. At this time, the vertical guide rail 28 moves longitudinally therewith and drives the adsorption frame 211 and the first vacuum suction cup 212 thereon to be located on the stacked single board. The telescopic shaft of the cylinder 210 extends to drive the vertical slider 29 to move vertically downward. At this time, the adsorption frame 211 and the first vacuum suction cup 212 thereon move downward and make the first vacuum suction cup 212 abut against the single board. The first vacuum suction cup 212 negatively adsorbs the single board. Then the telescopic shaft of the cylinder 210 retracts to drive the vertical slider 29 to move vertically upward and make the single board higher than the conveyor 10. Then the first motor 24 reverses to drive the longitudinal guide block 23 to slide in the opposite direction. At this time, the first vacuum suction cup 212 and the single board thereon move toward the conveyor 10 and move above the conveyor 10. At this time, the negative pressure of the first vacuum suction cup 212 is released, and the single board falls downward onto the conveyor 10 and is transported by the conveyor 10.

[0058] A cross bar 11 is fixedly provided at the upper front end of the conveyor 10. When the first vacuum suction cup 212 moves with the single board to the top of the conveyor 10, it is located below the cross bar 11. At this time, when the negative pressure of the first vacuum suction cup 212 is released, the telescopic shaft of the cylinder 210 continues to retract and drives the adsorption rack 211 to continue to move upward. At this time, if the single board cannot fall automatically, the cross bar 11 can contact the single board and make the single board fall. It can be understood that the cross bar 11 and the adsorption rack 211 are misaligned to ensure that the adsorption rack 211 will not interfere with the cross bar 11 when moving upward.

[0059] The end of the first robot arm 50 is provided with a second vacuum cup 51 for sucking wood chips to place the wood chips on the defects of the single board. The implementation principle of the second vacuum cup 51 is similar to that of the first vacuum cup 212, and both are equipped with a vacuum generator, a solenoid valve, and a hose.

[0060] The wood chip placement table 40 is provided with a plurality of wood chip placement slots 41 of different sizes for placing wood chips of different sizes to accommodate defects of different sizes.

[0061] The conveyor 10 is provided with a proximity sensor 12 at a position forward of the second robot arm 60 for detecting whether the single board is close to the second robot arm 60 .

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
