Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wood board paint spraying, and particularly relates to an automatic feeding and discharging equipment for an inductive paint spraying room. BACKGROUND

[0002] Wood board paint spraying is an important link in surface treatment of wood furniture, decorative board and other products, and the paint spraying quality directly affects the appearance and durability of the products. In order to reduce labor intensity and improve efficiency, some production lines have tried to use automatic feeding and discharging and paint spraying equipment. However, the automatic paint spraying still has the following defects: insufficient paint spraying pressure, too high viscosity, too fast solvent volatilization, and uneven spraying, which will cause the surface to present concave-convex lines; oil stains, silicone oil, wax pollution or high air humidity on the surface will cause partial small pits or bare bottom of the paint film; wood surface bubbles or substrate moisture escaping will cause small holes in the paint film; high moisture content of wood, insufficient drying, and water vapor expansion will cause partial paint film to bulge; too thick paint film, too fast drying, and wood expansion stress will cause fine crack grids on the surface.

[0003] These serious defects usually need to be removed from the production line in time, and after surface treatment, they are sent back to the production line for re-spraying or discarded. However, the current automatic production line will detect defects after spraying both sides of the wood, and since there is a situation of overall scrapping due to single-sided defects, it means that even if one side has a problem, the other side will be completed after wasting paint, time and energy, causing an invalid process and increasing the rework and scrap rate.

[0004] Some production lines also use mechanical arm grabbing systems to perform feeding and discharging actions. Such systems can realize automatic carrying and positioning of the board through program control, and to some extent, replace manual operation. However, the existing automatic feeding and discharging technology still has the following shortcomings: the procurement, installation and maintenance costs of the mechanical arm and other automatic systems are high; the adaptability of the mechanical arm to the shape, size and weight of the wood board is limited, and frequent parameter adjustment or even replacement of the end effector is required when switching different specifications of products, affecting the production continuity.

[0005] Patent No. CN112044659A discloses a plate paint spraying and drying device for automobile production. The device reverses the plate on the conveying roller through a horizontal moving assembly, so that the plate deviates from the original direction and enters the return table, and then the plate re-enters the paint spraying cavity for paint spraying treatment. The height of the moving roller perpendicular to the conveying direction of the conveying roller is adjustable, and the contact state of the plate with the conveying roller or the moving roller can be controlled through this control means, thereby controlling the advancing direction of the plate. However, this transfer method needs to integrate the driving mechanism, lifting mechanism and spring mechanism of the moving roller, which is difficult to achieve in technology, and the moving roller is prone to vibration when rotating, so the equipment is not very stable. SUMMARY

[0006] The purpose of the present invention is to provide an automatic loading and unloading device for an induction paint spraying room to solve the problems raised in the above-mentioned prior art.

[0007] Provide an automatic loading and unloading equipment for an induction spray paint room, including: A main conveyor belt, with first transfer platforms provided at both ends; A first painting line is connected to one end of the main conveyor belt via a first transfer platform; A second painting line is connected to the other end of the main conveyor belt via a first transfer platform, and a second transfer platform is provided between the second painting line and the first painting line; The return belt is located between the second transfer platform and the main conveyor belt.

[0008] As a further solution of the present invention: the first transfer platform includes a linear guide rail, a first lifting cylinder and an execution gripper, the first lifting cylinder moves axially on the linear guide rail, and the execution gripper is arranged at the output end of the first lifting cylinder.

[0009] The first transfer platform uses linear guides to provide a stable horizontal path, while the first lift cylinder achieves vertical lift, positioning the gripper to the wood panel for pick-up and placement. This ensures a stable connection between the main conveyor belt and the first painting line, ensuring smooth transfer of wood panels between different heights and conveying directions, minimizing surface damage and positional deviation caused by unstable transfer, and improving painting positioning accuracy.

[0010] As a further solution of the present invention: the second transfer platform includes a three-way moving mechanism, a second lifting cylinder and an execution gripper. The second lifting cylinder has the freedom to move toward the first paint line, the second paint line and the return belt through the three-way moving mechanism. The execution gripper is arranged at the output end of the second lifting cylinder and can perform a flipping action on the wooden board.

[0011] The second transfer platform, equipped with a three-way movement mechanism and a second lift cylinder, allows for flexible switching between the first and second painting lines and the return conveyor. Grippers are used to perform flipping or direct transfer. After the first side is painted, the inspection results directly determine the direction of the board's flow: qualified products are flipped and sent to the second painting line for a second side, while defective products are sent directly to the return conveyor for rework. This avoids ineffective painting, improves flexibility in production cycle control, and enhances resource utilization.

[0012] As a further solution of the present invention: the execution gripper includes a mounting platform and a plurality of telescopic cylinders, and the plurality of telescopic cylinders are arranged on the mounting platform.

[0013] The gripper consists of a mounting platform and multiple telescopic cylinders that independently extend and retract to adjust the gripping range and force. This adapts to the gripping needs of wood panels of varying sizes and thicknesses, eliminating the need to change the end effector when handling return workpieces or orders with varying specifications, thus increasing production line switching speeds.

[0014] As a further solution of the present invention: the execution gripper includes a mounting platform and a plurality of clamping members, and the wooden board can be confined between the plurality of clamping members by the elastic deformation performance of the clamping members.

[0015] The gripper is equipped with multiple elastically deformable clamping elements, which deform to securely hold the wood plank between multiple gripping points. This gripping mechanism requires no power. Instead, downward pressure from a lifting cylinder creates interference between the clamping elements and the wood plank, converting this interference force into a deformation effect. This simplifies the gripper's structure and reduces system operational complexity.

[0016] As a further solution of the present invention: the clamping member includes a deformation section, a necking section and an inclined transition section arranged in sequence from top to bottom.

[0017] The deforming section absorbs the interference stress and deforms, forcing the board into the necking section. The board has a slight travel between the necking sections, and the bottom section provides support for the board. When the clamping member tilts, the board slides onto the conveyor line under gravity. The inclined transition section acts as a guide, ensuring smooth entry into the necking section. The extended structure of the inclined transition section also provides support for the board.

[0018] As a further solution of the present invention: an adjusting member is provided between the clamping member and the mounting platform.

[0019] By adding an adjustment piece between the clamping piece and the mounting table, the clamping position of the clamping piece can be changed through adjustment, which can quickly adapt to wooden boards of different sizes and meet the transportation needs of different batches of products.

[0020] As a further solution of the present invention: the execution gripper includes a mounting platform, a rotating plate and an execution cylinder, the rotating plate is hinged to one side of the mounting platform and the rotating plate has an extension portion relative to the edge of the mounting platform, one end of the execution cylinder is hinged to the mounting platform and the other end is hinged to the extension portion of the rotating plate.

[0021] The actuator gripper consists of a rotating plate hinged to the mounting platform and an actuator cylinder. The actuator cylinder pushes on the plate's extension, driving the plate to rotate about its hinge point on the mounting platform. When the gripper is used to place and retrieve a plank, a small rotation of the plate tilts the gripper, allowing the plank to slide onto the conveyor line under gravity. When the gripper is used to flip a plank on the second transfer platform, a large rotation of the plate flips the actuator gripper, completing the flip. As a further scheme of the present application: the three-way moving mechanism comprises an X-axis guide rail and a Y-axis guide rail, and the second lifting cylinder moves axially on the Y-axis guide rail.

[0022] The three-way moving mechanism adopts a double-axis moving combination of the X-axis guide rail and the Y-axis guide rail, and the second lifting cylinder moves along the Y-axis guide rail, thereby forming a three-dimensional movement capability of horizontal double degrees of freedom and vertical lifting. The second transfer table is ensured to accurately and quickly switch between multiple workstations, and time loss in defect board rejection or wood board overturning paths is reduced.

[0023] As a further scheme of the present application: the three-way moving mechanism comprises an X-axis guide rail and a Y-axis guide rail, and the second lifting cylinder moves axially on the Y-axis guide rail.

[0024] The three-way moving mechanism comprises a rotatable rotary table that drives the X-axis guide rail to rotate, thereby adjusting the working angle of the gripper. In the case of complex work station layout or different wood board placement directions, the gripping angle can be flexibly adjusted, the dependence on the consistency of the conveying belt and the work station direction is reduced, and the overall system arrangement degree of freedom is improved.

[0025] Compared with the prior art, the present application has the following beneficial effects: The wood boards are conveyed between different processes by the main conveying belt, the first transfer table sends the wood boards from the main conveying belt to the first paint spraying line or sends them back to the main conveying belt from the second paint spraying line, the second transfer table is responsible for selective transfer between the first paint spraying line and the second paint spraying line, and can be connected with the return belt, so that the painted wood boards can be directly returned to the workbench for processing when serious defects are detected, without the need to continue ineffective spraying. The segmented detection and diversion of the paint spraying process are realized, defects can be found and removed in time after the first face is painted, unnecessary second face spraying is reduced, paint waste, rework rate and production time are reduced.

It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0031] However, there will be cases of omission of unnecessary detailed description. For example, there are cases of omission of detailed description of well-known matters, repeated description of practically identical structures. This is to avoid the following description from becoming unnecessarily lengthy, facilitating understanding by those skilled in the art. In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0032] See also Figure 1 As shown in the figure, in an embodiment of the present invention, an automatic loading and unloading device for an inductive paint spray booth includes a main conveyor belt 1, a first paint spray line 2, a second paint spray line 3, and a return belt 4. A first transfer platform 5 is provided at each end of the main conveyor belt 1. The first paint spray line 2 is connected to one end of the main conveyor belt 1 via the first transfer platform 5. The second paint spray line 3 is connected to the other end of the main conveyor belt 1 via the first transfer platform 5, and a second transfer platform 6 is provided between the second paint spray line 3 and the first paint spray line 2. The return belt 4 is located between the second transfer platform 6 and the main conveyor belt 1.

[0033] The main conveyor belt 1 runs through the entire production line, transporting wood boards between different processes. Both ends of the main conveyor belt 1 are connected to the first transfer platform 5, ensuring smooth transition between different painting lines or transfer units. The main conveyor belt 1 transports unpainted wood boards to the first transfer platform 5, where they connect to the first painting line 2. When the painted wood boards return from the second painting line 3, the main conveyor belt 1 transports them to a downstream workstation for inspection or packaging.

[0034] In one embodiment, the wood board to be sprayed is sent to the main conveyor belt 1 by the upstream workbench and stopped at intervals, and is positioned by the sorting and positioning photoelectric detectors distributed on the main conveyor belt 1. The wood board in place is taken away by the first transfer platform 5 and sent to the first painting line 2 to complete the first side spraying. At the end of the first painting line 2 or after drying, a detection camera is set to shoot and run a defect recognition algorithm, including bumps, bubbles, exposed bottom, bulges, cracks, etc. The PLC issues instructions based on the test results. If it is qualified, it instructs the second transfer platform 6 to grab the wood board and turn it over to the second painting line 3. If it is unqualified, it instructs the second transfer platform 6 to place the wood board on the return belt 4 for direct rework or manual processing. The returned workpiece is sent to the rework workbench for processing via the return belt 4, and then sent back to the main conveyor belt 1 to enter the first painting line 2 cycle. When the detection camera detects that the paint surface has minor defects such as dust, since the dust can be removed by simple processing methods, it can be completed after painting on both sides and then transported to the workbench for processing.

[0035] Specifically, see Figure 2 As shown, the first transfer platform 5 includes a linear guide rail 51, a first lifting cylinder 52 and an execution gripper 7. In the material picking triggering stage, the main conveyor belt 1 slows down and stops when it detects that the plate has reached the picking position of the first transfer platform 5, and the PLC sends a material picking instruction. The first lifting cylinder 52 moves axially along the linear guide rail 51 to the material picking position, and the output end of the first lifting cylinder 52 moves downward, so that the execution gripper 7 contacts the plate to perform the clamping action. After clamping is completed, the first lifting cylinder 52 is retracted and moves along the linear guide rail 51 to the placement position of the first painting line 2, lowers the plate and unclamps. The execution gripper 7 resets to the standby position, and the linear guide rail 51 returns to the origin to prepare for the next cycle.

[0036] In particular, please refer to Figure 3 As shown, the second transfer station 6 includes a three-way moving mechanism 61, a second lifting cylinder 62, and an execution gripper 7. In the waiting task phase, after the detection result of the first paint spraying line 2 is obtained, the PLC issues a grabbing task to the second transfer station 6. The three-way moving mechanism 61 moves above the grabbed board, the second lifting cylinder 62 is lowered to the grabbing height, and the execution gripper 7 clamps the board. According to the detection result, different paths are executed. When the paint surface detection is qualified, the three-way moving mechanism 61 moves to the turnover position, the execution gripper 7 triggers the turnover action, and after the turnover is completed, the board is moved to the second paint spraying line 3 and placed; when the paint surface detection is unqualified, the three-way moving mechanism 61 moves to the corresponding position of the return belt 4 and places the board.

[0037] In one embodiment, please refer to Figure 3 As shown, the three-way moving mechanism 61 includes an X-axis guide rail 611 and a Y-axis guide rail 612. The X-axis guide rail 611 is driven in the direction extending between the first paint spraying line 2 and the second paint spraying line 3, and the Y-axis guide rail 612 is driven in the direction extending between the second transfer station 6 and the return belt 4. The X-axis guide rail 611 moves on the Y-axis guide rail 612, brings the second lifting cylinder 62 to the target interval, and issues a lowering command.

[0038] In one embodiment, please refer to Figure 4 As shown, the three-way moving mechanism 61 includes an X-axis guide rail 611 and a turntable 613, and the turntable 613 can drive the X-axis guide rail 611 to rotate. According to the layout of the workstations or the angle of the board feeding, the turntable 613 is first rotated to a predetermined angle, so that the X-axis guide rail 611 obtains the required working direction. After rotating to the position, the X-axis guide rail 611 performs lateral movement, and the second lifting cylinder 62 performs lifting action.

[0039] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 As shown, the execution gripper 7 includes a mounting table 71 and a plurality of telescopic cylinders 72 arranged on the mounting table 71. The mounting table 71 is fixed to the output end of the first lifting cylinder 52 or the second lifting cylinder 62. According to the current workpiece specification, the initial extension length command of the telescopic cylinder 72 is issued, and when the execution gripper 7 approaches the board, each telescopic cylinder 72 independently extends and retracts according to the preset or closed-loop feedback to contact the edge surface of the board, and is adjusted to the appropriate clamping pressure. Through the independent control of each telescopic cylinder 72, multi-point balanced force clamping of large boards or irregular edges is realized. After reaching the placement position, the telescopic cylinders 72 are retracted in sequence or are first loosened and then tilted to place the board. The telescopic cylinder 72 can realize force control, which helps to prevent overpressure when clamping the unhardened paint surface. Through group control, different sizes can be quickly adapted without replacing the end structure.

[0040] In one embodiment, please refer to Figure 2And Figure 6 As shown in the figure, the execution gripper 7 includes a mounting table 71 and a plurality of clamping pieces 73 arranged on the mounting table 71. The mounting table 71 is fixed to the output end of the first lifting cylinder 52. The first lifting cylinder 52 drives the mounting table 71 to press down, so that the clamping pieces 73 are in contact with the wood board. The clamping pieces 73 are deformed and clamp the board therebetween. This clamping scheme does not have an active clamping drive, but uses elastic deformation to generate clamping force.

[0041] Further, referring to Figure 7 As shown in the figure, the clamping piece 73 includes a deformation section 731, a necking section 732, and a bevel transition section 733 arranged in sequence from top to bottom. When the board approaches the clamping area, the bevel transition section 733 guides the board to smoothly enter the clamping area. With the clamping piece 73 pressed down, the deformation section 731 first absorbs the impact and elastically deforms, forcing the board to enter the necking section 732, which precisely positions and lifts the board in the radial direction. The bottom of the necking section 732 forms a local stress point to support the weight of the board, ensuring the stability of the board posture during transportation and turning.

[0042] It should be noted that when the board is located between the plurality of necking sections 732, there is a single degree of freedom in a single direction. When it needs to be released, the inclined clamping piece 73 is tilted, and the board slides out of the necking section 732 in the direction of the degree of freedom under the action of gravity or a guide slope, and is reset to the conveying surface along the slope. And when the board contacts the conveying surface, the conveying surface applies a friction force to the board in the conveying direction, further promoting the resetting of the board.

[0043] Further, referring to Figure 6 As shown in the figure, an adjusting piece 76 is arranged between the clamping piece 73 and the mounting table 71. When the production is changed or new materials are put into the line, the operator adjusts the radial position or inclination angle of the clamping piece 73 relative to the mounting table 71 through the adjusting piece 76, so that the clamping piece 73 matches the current board size. The adjusting piece 76 can be a bolt adjustment, a wedge, a sliding groove positioning, or a pneumatic / electric fine adjuster. After reaching the appropriate position, the adjusting piece 76 is locked and the current fixture configuration is recorded in the control system for quick switching next time.

[0044] In particular, referring to Figure 2 , Figure 3 , Figure 6 And Figure 8As shown, the execution gripper 7 comprises a mounting table 71 fixed to the output end of the first lifting cylinder 52 or the second lifting cylinder 62, a rotating plate 74 hinged to one side of the mounting table 71 and having an extension part relative to the edge of the mounting table 71, and an execution cylinder 75 hinged to the mounting table 71 at one end and hinged to the extension part of the rotating plate 74 at the other end. When the execution gripper 7 only needs to release the board at the placing position, the execution cylinder 75 pushes the rotating plate 74 to rotate by a small angle, so that the clamping piece 73 is tilted, and the board slides along the slope under the action of gravity to the conveying line. When the board needs to be turned over, the execution cylinder 75 drives the rotating plate 74 to rotate by a large angle, so that the orientation of the board is changed, thereby realizing the front and back surface conversion.

[0045] It should be noted that the present application is not limited to the above-described embodiments. The above-described embodiments are only examples, and embodiments having substantially the same configuration and playing the same role and effect as the technical idea within the scope of the technical solution of the present application are all included in the technical scope of the present application. In addition, within the scope of the gist of the present application, various modifications that can be thought of by those skilled in the art, other modes constructed by combining part of the elements of the embodiments are also included in the scope of the present application.
