Description

Technical Field

[0001] This invention relates to the field of labeling and processing technology for engineered wood products, specifically to an automated labeling device and method for classifying engineered wood products using visual guidance. Background Technology

[0002] In the production of engineered wood panels, accurately affixing labels to each panel is a crucial step connecting design and cutting. For a long time, this process has heavily relied on manual labor, with workers reading drawings, locating labels, and affixing them. This has resulted in low efficiency and labeling speed that restricts production rhythm. Furthermore, manual labeling is prone to errors due to visual fatigue or negligence, leading to incorrect cutting and waste of materials.

[0003] To address the aforementioned issues, some automated labeling devices have emerged in the existing technology. For example, the utility model patent with authorization announcement number CN216709919U discloses an automatic labeling mechanism for sheet materials. Its core lies in the use of a mechanical snap-fit ​​mechanism composed of a rotating shaft, a torsion spring, and a snap-fit ​​block to achieve rapid manual replacement of the labeling template. However, such solutions only optimize the hardware clamping efficiency. Their more prominent problem is that they generally use rigid contact methods such as mechanical piercing to pick up the label, which is very easy to damage the label, thus restricting the improvement of the quality and efficiency of the entire labeling process.

[0004] Therefore, it is necessary to design a solution that can automatically pick up and attach labels. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] correspond Figures 1 to 10 As shown, the device includes a support 1, which is a rigid frame welded as a whole, providing stable support for the equipment. The outer side of the support 1 is equipped with a control cabinet 2 and a frame slide rail 6. The inner side of the support 1 is equipped with a lifting mechanism 3 with a worktable 4. The worktable 4 is used to place the artificial board to be labeled stably. The lifting mechanism 3 is a scissor-type electric lifting platform, and the height of the worktable 4 can be adjusted according to the thickness of the board.

[0021] The frame slide rail 6 adopts a linear guide rail structure, on which a movable frame 7 is slidably connected via a first drive mechanism and spans above the workbench 4; the first drive mechanism is a servo motor combined with a gear and rack transmission mechanism, used to drive the movable frame 7 to move along the frame slide rail 6 in the overall direction of the production line.

[0022] The mobile frame 7 is equipped with a motion mechanism 8, which includes an X-axis linear module, a Y-axis linear module, and a Z-axis linear module arranged orthogonally to each other. The three linear modules form a three-dimensional rectangular coordinate system. The labeling execution module 12 is fixedly installed at the execution end of the Z-axis linear module and can follow the three linear modules to complete lifting and moving actions within the motion mechanism 8.

[0023] An integrated label supply module 11 is also fixedly installed on the support 1. The integrated label supply module 11 is equipped with a conveying device, a paper roll take-up roller 110 and a label printer 111. The label printer 111 has a built-in release roller. The raw material roll, which is composed of the base paper 1211 and the label paper 1212 on its surface, is installed on the release roller. The base paper is drawn out from the paper output end of the label printer 111 and travels around the conveying device. The end of the base paper is fixed on the paper roll take-up roller 110. The paper roll take-up roller 110 continuously completes the recycling of waste base paper.

[0024] The labeling execution module 12 includes a mounting plate 9, a first vision module 10, a labeling head 13, and a label peeling plate 14. The first vision module 10 is mounted on the mounting plate 9, with its lens pointing vertically downward toward the worktable 4. The labeling head 13 is mounted on the output end of the second drive mechanism at the bottom of the mounting plate 9. The second drive mechanism is a lifting and rotating integrated servo electric cylinder, with its lifting axis and rotation axis arranged vertically and coaxially, which can drive the labeling head 13 to achieve vertical lifting and horizontal angular rotation. The label peeling plate 14 is located on one side of the labeling head 13, with a peeling blade with an acute angle structure at its front end. The label peeling plate 14 is hollow inside and contains a label-removing mechanism for flexible and non-destructive label removal.

[0025] The conveying device includes a T-shaped frame 112, a support plate seat 113, and a conveyor belt 118. The T-shaped frame 112 is fixedly installed inside the integrated label supply module 11 near the top. The top of the integrated label supply module 11 has an opening to facilitate the labeling execution module 12 to extend into and perform label picking operations. When not in use, a dust cover can be configured to seal and protect the opening. The support plate seat 113 is fixed on the T-shaped frame 112, and the two form a rigid frame. The support plate seat 113 has an arc-shaped structure with a concave center and convex ends. Bearing supports 114 and rotating rollers 115 are evenly installed on the outer surface of the support plate seat 113. Two sets of toothed rings 1115 and rotating rings 1116 connected by hollow tubes 116 are symmetrically arranged at both ends of the inner surface of the support plate seat 113. One end of the hollow tube 116 is rotatably equipped with a fixed rotary joint 117, and the other end of at least one set of hollow tubes 116 is connected to a conveying drive motor.

[0026] The outer surface of the support plate 113 is covered with a conveyor belt 118, which is made of wear-resistant silicone material. The inner side of the conveyor belt is provided with a toothed groove 1112 that meshes with the toothed ring 1115, and a transition groove 1111 that fits into the bearing support 114 and the rotating roller 115. When the conveyor drive motor drives the hollow tube 116 to rotate, it drives the toothed ring 1115 and the rotating ring 1116 to rotate synchronously. Through the meshing transmission of the toothed groove 1112, the conveyor belt 118 is driven to follow the specific shape and structure of the support plate 113.

[0027] The surface of the conveyor belt 118 is uniformly provided with adsorption holes 119, which are connected to the negative pressure air supply component. The conveyor belt 118 can adsorb and fix the bottom paper 1211 of the label paper 1212 through negative pressure. The conveyor belt 118 is provided with multiple sets of parallel straight air guide tubes 1110 and annular air guide tubes 1113 arranged around the circumference of the conveyor belt 118. The two ends of the straight air guide tubes 1110 are connected to the adsorption holes 119 and the annular air guide tubes 1113, respectively. The annular air guide tubes 1113 are uniformly provided with multiple semi-circular seats 1114 that are adapted to the shape of the ball head 1120. The center of the semi-circular seat 1114 is provided with an air vent that communicates with the inner cavity of the annular air guide tube 1113, providing an airflow channel for negative pressure adsorption.

[0028] The negative pressure air supply assembly consists of a rotating ring 1116, an outer conduit 1117, a moving tube 1119, a ball head 1120, a solenoid valve 1121, and a spring 1122. The rotating ring 1116 has an annular air passage inside and a vent hole 1118 connecting the annular air passage to the internal cavity of the hollow tube 116. Multiple outer conduits 1117 are evenly arranged along the circumferential direction on the front end face of the rotating ring 1116 facing the conveyor belt 118. Each outer conduit 1117 has an axially movable moving tube 1119 inside. The front end of the moving tube 1119 is provided with a ball head 1120 with a through hole. The end of the moving tube 1119 is provided with a solenoid valve 1121. A spring 1122 is sleeved on the outer wall of the moving tube 1119. The two ends of the spring 1122 abut against the inner wall of the outer conduit 1117 and the limiting step of the moving tube 1119, respectively, so as to realize that the moving tube 1119 slides under pressure and automatically rebounds and resets when the force is released.

[0029] During the operation of the conveyor belt 118, when the ball head 1120 rotates to fit against the semicircular seat 1114, the ball head 1120 pushes the moving tube 1119 inward, triggering the solenoid valve 1121 to open. At this time, the negative pressure air source passes through the fixed rotary joint 117, hollow tube 116, vent hole 1118, rotating ring 1116, moving tube 1119, ball head 1120, semicircular seat 1114, annular air guide tube 1113 and straight air guide tube 1110 in sequence, and finally acts on the adsorption hole 119, adsorbing the bottom paper 1211 with the label paper 1212 attached to the surface of the conveyor belt 118. When the ball head 1120 separates from the semicircular seat 1114, the solenoid valve 1121 closes, and the negative pressure of the corresponding area adsorption hole 119 disappears, realizing that only the label area maintains negative pressure adsorption.

[0030] The negative pressure air source acting on the conveyor belt 118 has a vacuum air pressure valve connected in series on the external pipe connected to the fixed rotary joint 117, which can adjust the negative pressure as needed. When the air path maintains a low negative pressure, the adsorption hole 119 generates a weak adsorption force, which only slightly adheres the bottom paper 1211 to the surface of the conveyor belt 118 to prevent the paper from deviating. Because the adsorption force is small, the paper roll take-up roller 110 behind normally pulls the waste bottom paper for recycling, and there will be no pulling or tearing problems. When the label paper 1212 moves to the label taking area, the air path switches to a high negative pressure to fix the bottom paper 1211 on the conveyor belt 118. After the label is taken, the air path automatically switches to a low negative pressure, and the bottom paper 1211 returns to its following state, continues to be conveyed backward and recycled by the paper roll take-up roller 110.

[0031] The label-peeling plate 14 has a label-taking mechanism inside, including a support frame 121 and a second vision module. The second vision module is fixed to the bottom of the support frame 121 by a bracket, and the lens faces the label-taking area of ​​the conveyor belt 118. Two rotatable shafts 122 are installed in parallel on the support frame 121. The axes of the two shafts 122 are perpendicular to the running direction of the conveyor belt 118. One of the shafts 122 is driven by a steering motor 123 fixed on the support frame 121. The steering motor is a servo motor and is connected to the industrial control computer. Semi-circular toothed discs 124 that mesh with each other are installed at both ends of the two shafts 122. When the steering motor 123 drives one of the shafts 122 to rotate, the meshing transmission of the semi-circular toothed discs 124 drives the two shafts 122 to rotate synchronously in opposite directions.

[0032] Both semi-circular toothed discs 124 have external electric telescopic rods 127 fixed vertically downwards at the bottom of their surfaces. An adsorption plate 128 is fixed to the piston rod end of the external electric telescopic rod 127. An adsorption through hole is opened on the lower surface of the adsorption plate 128. The adsorption plate 128 is connected to a negative pressure air source through a hose 129. A negative pressure solenoid valve connected to the industrial control computer is installed on the hose 129. An internal electric telescopic rod 125 is installed at the bottom center of the support frame 121 through a swing hinge seat. The internal electric telescopic rod 125 can swing back and forth along the length of the label paper 1212. A silicone pressure roller 126 is installed at the piston rod end of the inner electric telescopic rod 125 for rolling and flattening the label during labeling.

[0033] Both the first vision module 10 and the second vision module include an industrial camera, as well as a vision calibration module, a vision positioning module, a vision measurement module, and a board classification module that are matched with the industrial camera. The dual-channel industrial camera and vision kit that are standard with the L-series labeling machine can be selected to realize board specification recognition and online label quality inspection. Alternatively, the dual vision architecture used in the LVS-6108 label inspection equipment can be used to complete multi-dimensional identification and judgment of board material, specifications, and defects. Based on the image data collected by the industrial camera, the board classification module can sequentially complete multi-dimensional identification and classification of board material, specifications, batch, defects, and intended use.

[0034] The control cabinet 2 is equipped with an industrial computer, which is connected to the lifting mechanism 3, the frame slide rail 6, the moving frame 7, the motion mechanism 8, the integrated label supply module 11, and the labeling execution module 12 via an industrial bus. The industrial computer has a built-in labeling control timing program adapted to visual classification, timing linkage, and closed-loop quality inspection. Through the industrial bus, it coordinates the coordinated actions of all mechanical, pneumatic, and drive components of the whole machine to realize the automatic coordinated operation of each process of label picking, transfer, positioning, affixing, and flattening.

[0035] The equipment control system is composed of control programs mounted on the industrial control computer inside the control cabinet. This control system adopts an eye-to-hand calibration method to unify the visual coordinate system and the mechanical coordinate system. The first vision module 10 calculates the actual position and labeling coordinates of the board and automatically compensates for the rotation angle when the board is placed at an angle. The second vision module detects the label's positioning status and degree of tilt in real time and dynamically compensates for the label picking coordinates. This part of the function can be implemented using the built-in eye-to-hand calibration function library of the VPLC series vision motion control integrated machine and the coordinate offset compensation program of the IS650 servo driver.

[0036] Based on the aforementioned control system, a closed-loop quality inspection system for the entire label and finished product process is established: the second vision module detects the label printing quality and shape integrity, etc., and unqualified labels are not picked up and continue to be conveyed along the conveyor belt with the backing paper, and finally wound up by the paper roll winding roller; the first vision module 10 completes the final inspection after labeling, and detects indicators such as labeling position deviation and QR code readability. If it is determined to be an unqualified product, a diversion instruction can be automatically triggered to send it to the rework channel, thus realizing full-process quality control.

[0037] The bottom of the labeling head 13 is equipped with an adhesion block, which is made of elastic silicone material to ensure the initial contact stress and uniform pressure distribution. It is used to compact the label that has been applied by the labeling mechanism.

[0038] Working principle of this invention: 1. Loading and positioning: The production line conveyor sends the artificial board to be labeled to the surface of the workbench 4. The lifting mechanism 3 drives the workbench 4 to adjust the height according to the actual thickness of the board, so that the board maintains the standard working posture. The first vision module 10 collects the board image, completes the board classification and recognition, and calculates the actual posture of the board and the coordinates of the labeling point and transmits them to the industrial control computer. 2. Label Picking and Shifting: The industrial control computer controls the moving frame 7 and the motion mechanism 8 to move together, adjusting the motion mechanism 8 above the integrated label supply module 11. Then, the Z-axis linear module of the motion mechanism 8 is activated to drive the labeling execution module 12 to extend downward in the vertical direction. Then, the X and Y-axis linear modules of the motion mechanism 8 are activated in conjunction to adjust the horizontal position of the labeling execution module 12. At the same time, the labeling execution module 12 is rotated horizontally to correct its posture until the label picking mechanism moves to directly above the label picking area of ​​the conveyor belt 118, completing the pre-label picking and positioning. 3. Label preparation: The industrial control computer commands the integrated label supply module 11 to start, and the label printer 111 prints the corresponding label according to the preset cutting information of the board. The paper roll take-up roller 110 rotates and guides the printed label paper 1212 to the label picking area of ​​the conveyor belt 118. After the second vision module detects that the label paper 1212 is in place, the conveyor belt 118 stops rotating. 4. Label Pre-Separation: The inner electric telescopic rod 125 drives the pressure roller 126 to press down, pressing the middle of the label paper 1212 against the central recess of the conveyor belt 118. The negative pressure air source switches to high negative pressure operation. The backing paper 1211 bends along the arc contour of the conveyor belt 118 based on its own stiffness, and its two ends are adsorbed and fixed to the two protrusions at the ends of the conveyor belt 118. This causes the backing paper 1211 to generate rebound stress. Since the label paper 1212 is relatively soft, this rebound stress continues to act on the two edges of the label paper 1212, thereby causing the label paper 1212 and the backing paper 1211 to form a pre-separation at the edge position and maintain a raised state; if the label paper 1212 fails to separate from the backing paper 1211 at the edge, the label paper 1212 will be pre-separated from the backing paper 1211. If the label 1211 is not fully raised, the peeling plate 14 moves down, so that its peeling edge is close to the highest point of the protrusion at the output end of the conveyor belt 118, forming an acute angle with the surface of the conveyor belt 118. The gap between the peeling edge and the surface of the conveyor belt 118 is slightly smaller than the thickness of the label 1212, but allows the backing paper 1211 to pass freely. The conveyor belt 118 works again, driving the backing paper 1211 to rotate and slide under the peeling edge. The edge of the label 1212, which has a certain thickness, comes into contact with the peeling edge and is pried up. After being pried up, the conveyor belt 118 stops again, and the edge of the label 1212 is pried up from the backing paper 1211, assisting in completing the pre-separation.

[0039] 5. Non-destructive label removal: The steering motor 123 drives the two rotating shafts 122 to rotate in opposite directions, thereby adjusting the adsorption plate 128 to an angle and spacing that is compatible with the edges of the pre-separated raised label paper 1212. Subsequently, the adsorption plate 128 moves down and uses negative pressure to flexibly adsorb the raised edges of the label paper 1212. At this time, the pressure roller 126 moves up to release the pressure on the middle of the label paper 1212. The label paper 1212 is peeled off smoothly and completely from the backing paper 1211 under the negative pressure of the adsorption plate 128, without any rigid damage throughout the process. 6. Labeling Process: After labeling, the motion mechanism 8 drives the labeling execution module 12 to move upward, completely moving it out of the integrated label supply module 11 area. Through the coordinated operation of the frame slide rail 6, the moving frame 7, and the motion mechanism 8, the labeling mechanism with the label paper 1212 moves to above the calculated labeling point on the board and extends close to the labeling point. At this time, the two outer electric telescopic rods 127 are driven to flatten the label paper 1212, and the inner electric telescopic rod 125 drives the pressure roller 126 to move downward, first flattening the label paper 1212... The label 1212 is attached to the labeling point in the middle. Then, the outer electric telescopic rod 127 is adjusted to attach both ends of the label 1212 to the labeling point. The suction plate 128 releases both ends of the label 1212, so that the label 1212 is spread on the labeling point. The inner electric telescopic rod 125 drives the pressure roller 126 to swing and roll back and forth on the surface of the label 1212, initially smoothing the label and removing air bubbles. Subsequently, the label taking mechanism retracts, the position of the labeling head 13 is adjusted, and the label 1212 is pressed down to compact it, thereby completing the labeling.

[0040] 7. Final quality inspection and reset: When the label paper 1212 is conveyed to the label picking area, the second vision module first completes the label quality inspection; after the first vision module 10 completes the labeling, the final quality inspection is carried out. Qualified boards are conveyed to the next process by the production line, and unqualified products trigger the diversion instruction; after the labeling is completed, each execution module and mechanism is reset, the conveyor belt 118 updates the next label, and the system enters the next work cycle.
