Technical Field

[0001] The present invention relates to the technical field of grinding devices, and more specifically, to a grinding device for processing furniture boards. Background Art

[0002] During the production and processing of existing furniture boards, there are often defects such as depressions, scratches, and holes on the surface of the boards. Multiple processes such as detection, repair, and grinding are required to ensure the appearance quality of the boards and the subsequent painting effect. Generally, this series of technological processes includes steps such as defect detection, marking of defect areas, filling and repair, and surface grinding, which are important links in the board processing production line.

[0003] However, in the prior art, the detection and repair of board defects mostly rely on manual visual inspection and manual operation, and both sides of the board need to be operated. There are problems such as low detection efficiency, poor accuracy, and high labor intensity. The manual grinding and filling steps are greatly affected by the technical level of the operators, resulting in difficulty in ensuring product consistency. Moreover, due to the lack of automatic linkage, it is often difficult to efficiently integrate functions such as detection, repair, and grinding in a timely and accurate manner, which affects the automation and intelligence levels of furniture board production and restricts the improvement of the production efficiency and product quality of the industry.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a grinding device for processing furniture boards. Summary of the Invention

[0005] The purpose of the present invention is to provide a grinding device for processing furniture boards to solve the above problems.

[0006] To achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] A grinding device for processing furniture boards includes: a processing base, a pretreatment component, and a grinding component. Positioning guide rails are arranged on both sides of the processing base, and an electric clamping plate is installed in the middle of a pair of the positioning guide rails.

[0009] As a further improvement of the present invention, a visual recognition block and a detection strip are installed on the moving block.

[0011] As a further improvement of the present invention, when the color-changing functional layer is not subjected to external force and does not deform, it appears as a first predetermined color as a whole. When the detection strip undergoes local bending, stretching, or compression and other deformations under the action of external force, only the color-changing functional layer in the deformed area changes from the first predetermined color to a second predetermined color, and this area returns to the first predetermined color or remains the second predetermined color after the deformation is eliminated.

A hydraulic rod is installed inside the grinding block, and the output end of the hydraulic rod is fixedly connected to a slider. A rotating block is installed on the slider, and an electric grinding roller is installed on the pair of rotating blocks.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] (1) This solution integrates multiple functional modules such as sheet defect detection, automatic defect marking, feeding repair, and surface grinding.

[0019] (2) Secondly, the detection component adopts the detection methods of visual recognition and magnetic induction, which can highly sensitively and non-contactingly identify the minute defects on the surface and near the surface of the sheet. Through the intuitive response of the color-changing functional layer and the multi-signal fusion determination, it effectively avoids the influence of factors such as ambient light and surface color difference on the detection accuracy. This design not only improves the accuracy of defect detection but also can classify and distinguish different types and depths of defects, providing accurate data support for subsequent processes.

The filling component combines camera vision positioning, multi-dimensional movement of the grinding ball, and the synergistic effect of the magnetic extrusion block to ensure that the filling agent can fully penetrate and firmly bond in the defect area. At the same time, with fine grinding, it realizes the seamless connection between the repaired area and the original surface of the sheet.

[0021] (4) The grinding component adopts multiple groups of adjustable electric grinding rollers, combined with a hydraulic system to ensure automatic adjustment of grinding pressure, angle, and depth. It can adapt to plates with different thicknesses and surface conditions, achieving efficient, uniform, and fine surface treatment. The overall structure is highly automated, capable of flexibly adjusting various parameters according to different plate specifications and defect conditions, improving the adaptability and versatility of processing. It not only greatly enhances the automation and intelligence level in the production process of furniture plates, ensures the consistency and high standards of product quality, but also significantly reduces manual labor intensity and human errors, improves production safety and the production management level of the enterprise, and has broad industrial application prospects and significant economic and technological value.

DETAILED DESCRIPTION OF THE INVENTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment:

[0033] Please refer to Figures 1-7 , a grinding device for processing furniture plates, comprising: a processing base 1, a pretreatment assembly 2 and a grinding assembly 6. Positioning guide rails 11 are arranged on both sides of the processing base 1, and an electric clamping plate is installed in the middle of a pair of positioning guide rails 11. The electric clamping plate is used for clamping the plate. A fixed cross beam 12 is installed at the top of the processing base 1, and a pair of pretreatment assemblies 2 are arranged on the processing base 1; the pair of pretreatment assemblies 2 are symmetrically arranged. The pretreatment assembly 2 includes a mounting plate 21, the mounting plate 21 is fixedly connected to the inner wall of the fixed cross beam 12, and a detection assembly 3, a marking assembly 4 and a filling assembly 5 are arranged on the mounting plate 21. The marking assembly 4 is arranged in the middle of the detection assembly 3 and the filling assembly 5. The detection assembly 3 is used to detect the plate, the marking assembly 4 is used to mark the detected plate, and the filling assembly 5 is used to fill the marked plate; the grinding assembly 6 is used to grind the plate after detection and filling.

[0034] Among them, the device mainly includes a processing base 1, a pretreatment assembly 2 and a grinding assembly 6. Positioning guide rails 11 are arranged on both sides of the processing base 1, and an electric clamping plate is installed in the middle of a pair of positioning guide rails 11, which can accurately clamp and position the plate, ensuring the stability and processing accuracy in the subsequent processing process. A fixed cross beam 12 is installed at the top of the processing base 1, providing a solid structural foundation for the installation and operation of each functional module.

[0035] The pretreatment assembly 2 of the present device is symmetrically arranged on the processing base 1 and includes a mounting plate 21, which is fixedly connected to the inner wall of the fixed cross beam 12, with a stable structure. A detection assembly 3, a marking assembly 4 and a filling assembly 5 are sequentially arranged on each mounting plate 21, and the marking assembly 4 is arranged between the detection assembly 3 and the filling assembly 5, forming a reasonable process flow. The detection assembly 3 can automatically detect the surface or internal defects of the plate, the marking assembly 4 automatically marks the defective parts according to the detection results, and the filling assembly 5 automatically replenishes and repairs the marked defective areas to ensure that the defects can be processed in a timely and accurate manner.

[0036] The automatic integration of detection, marking and feeding enables defect identification and repair of the board before it enters the subsequent grinding process, greatly improving the processing efficiency and the finished product rate. Finally, the grinding component 6 performs uniform and fine grinding on the surface of the pre-treated board, further improving the flatness and smoothness of the board surface. The setting of the grinding component 6 ensures that the surface of the board after repair has a natural transition and no obvious processing marks, meeting the strict requirements for the quality of the board in high-standard furniture manufacturing.

[0037] By organically combining functions such as detection, marking, feeding and grinding, this device realizes the automation and intelligence of the furniture board processing process, significantly improves the production efficiency and product consistency, reduces the labor intensity, and has extremely high practical value and broad application prospects.

[0038] The detection component 3 includes a monitoring block 31, which is fixedly connected to the inner wall of the mounting plate 21. The top of the monitoring block 31 is fixedly connected to a motor 33, and the output end of the motor 33 is fixedly connected to a reciprocating lead screw 32. A nut sleeve is installed outside the reciprocating lead screw 32, and one end of the nut sleeve is fixedly connected to a moving block 34.

[0039] A visual recognition block 35 and a detection strip 36 are installed on the moving block 34. The detection strip 36 is arranged below the visual recognition block 35. An electromagnetic strip 37 is fixedly connected to the monitoring block 31, and the electromagnetic strip 37 is arranged on one side of the detection strip 36.

[0040] The detection strip 36 includes an elastic matrix layer and a color-changing functional layer covering the surface of the matrix layer. A magnetic strip is embedded in the elastic matrix layer. The color-changing functional layer is made of a color-changing material sensitive to mechanical stress or deformation, and is fixedly connected to the matrix layer, with a thickness of 0.1 - 1 mm.

[0041] When the color-changing functional layer is not affected by external forces and does not deform, it appears as a first predetermined color as a whole. When the detection strip 36 undergoes local bending, stretching or compression and other deformations under the action of external forces, only the color-changing functional layer in the deformed area changes from the first predetermined color to the second predetermined color, and this area returns to the first predetermined color or remains the second predetermined color after the deformation is eliminated.

[0042] Among them, the detection component 3 is used to realize the automatic detection of board defects. Its structure includes a monitoring block 31, which is fixedly connected to the inner wall of the mounting plate 21, playing a role of support and positioning. The top of the monitoring block 31 is fixedly connected to a motor 33, and the output end of the motor 33 is fixedly connected to a reciprocating lead screw 32. After the motor 33 is powered on, it can drive the reciprocating lead screw 32 to rotate, thereby driving the nut sleeve installed outside it to perform an axial reciprocating motion. One end of the nut sleeve is fixedly connected to a moving block 34. Through the control of the motor 33, the moving block 34 can move up and down along the axis of the monitoring block 31 to realize the adaptive detection of boards with different thicknesses or positions.

[0043] The moving block 34 is provided with a visual recognition block 35 and a detection bar 36, wherein the detection bar 36 is arranged at the lower side of the visual recognition block 35, and the visual recognition block 35 is used to monitor the color change of the surface of the detection bar 36 in real time, so as to capture the plate defect information in time. The side wall of the monitoring block 31 is fixedly connected with an electromagnetic bar 37, which is arranged at one side of the detection bar 36 and can adjust the output magnetic field strength as needed to apply a controllable magnetic force to the magnetic bar inside the detection bar 36.

[0044] The detection strip 36 is the core detection unit of the device, and its structure includes an elastic matrix layer, a magnetic strip is embedded inside the elastic matrix layer, and a color-changing functional layer is covered on the outer surface. The color-changing functional layer is made of a color-changing material that is sensitive to mechanical stress or deformation, and is firmly combined with the elastic matrix layer. The thickness is controlled between 0.1 and 1 mm. When the color-changing functional layer is not subjected to external force and is not deformed, the whole color appears to be a first predetermined color, such as blue or other basic colors. When the detection strip 36 is subjected to external force, such as the magnetic strip is enhanced by the magnetic force of the electromagnetic strip 37 and forms local stress concentration with the local defects of the plate to cause local bending, stretching or compression, etc., the color-changing functional layer of only the deformation area is changed from the first predetermined color to the second predetermined color, such as red or other eye-catching identification colors, and can be restored to the first predetermined color or maintained at the second predetermined color after the deformation is eliminated. Specifically, it can be a reversible or irreversible system according to the selected color-changing material.

[0045] By controlling the magnetic force output of the electromagnetic strip 37, the embedded magnetic strip is subjected to increased force in the defective area of the plate, causing the detection strip 36 to deform locally, thereby causing the color of the color-changing functional layer to change. The visual recognition block 35 can sensitively capture the color-changing area to achieve automatic identification and positioning of defects. This structural design can not only perform non-contact, high-sensitivity real-time detection of surface and internal defects of the plate, but also intuitively reflect the defect distribution through color change, which is convenient for subsequent automatic marking and replenishment.

[0046] It should be added that in order to ensure that the detection strip 36 can actively respond to smaller plate defects, the present device has made targeted optimizations in structure and control methods. First, the detection strip 36 uses a highly elastic material as the base layer, and uses a magnetic strip with high magnetic sensitivity to ensure that it can be sufficiently deformed when subjected to weak external force or slight magnetic force changes. Secondly, the color-changing functional layer uses a color-changing material that is extremely sensitive to tiny mechanical stresses, such as liquid crystal polymers, pressure-responsive color-changing polymers or other highly sensitive color-changing coatings. These materials can produce obvious color changes under extremely small deformation amounts, thereby amplifying the defect signal.

[0047] Meanwhile, the electromagnetic strip 37 has the ability to adjust the magnetic field strength, and can flexibly adjust the output magnetic force according to the detection requirements. When detecting minute defects, by increasing the magnetic force output of the electromagnetic strip 37, when the embedded magnetic strip is in the areas with defects such as minute depressions and scratches on the surface of the plate, the local magnetic field change will generate a force sufficient to cause local deformation of the detection strip 36. Even minute surface defects can be reliably identified by the detection strip 36.

[0048] In addition, the visual recognition block 35 is equipped with a high-resolution image sensor and an intelligent recognition algorithm, which can accurately capture and analyze minute color changes on the surface of the detection strip 36, further improving the detection sensitivity and accuracy for minute defects.

[0049] This device can also be combined with Hall elements to achieve real-time monitoring and feedback of minute magnetic field changes. Specifically, Hall elements are integrated on the detection strip 36 or in its adjacent area, such as mounted on the surface of the elastic matrix layer or embedded near the detection strip. The Hall element can accurately sense the change in the magnetic field strength at the position where the detection strip 36 is located.

[0050] During the detection process, when the electromagnetic strip 37 outputs a magnetic field, if there are minute defects on the surface of the plate, the embedded magnetic strip will be affected by external disturbances or local stress, resulting in minute changes in the surrounding magnetic field. The Hall element can then monitor this change in real time. At this time, the electrical signal generated by the Hall element can be used as an auxiliary criterion, combined with the color change of the color-changing functional layer by the visual recognition block 35, to achieve multiple determinations and highly sensitive responses to the plate defects.

[0051] This structure enables the detection system to still reliably identify and locate the defect area through the magnetic field change signal output by the Hall element when there are only extremely minute defects, the discoloration signal is not obvious, or the environmental light has a greater impact. Through linkage with the control system, the signal of the Hall element can also be used to dynamically adjust the magnetic force output of the electromagnetic strip 37 and the fitting pressure of the detection strip 36, realizing the adaptive optimization of the detection sensitivity.

[0052] The structure of this detection component is novel and ingenious. By using the composite integration of the elastic matrix, magnetic strip, and color-changing functional layer, it realizes the organic coordination of mechanical, electromagnetic, and optical signals, improves the accuracy and automation level of detection. Compared with traditional single mechanical or manual detection, it can greatly improve the detection efficiency and precision, reduce the manual labor intensity, and provide beneficial technical support for the automation upgrade of furniture board processing and grinding equipment.

An electric spray head is installed at the bottom end of the first electric slider 43. The electric spray head is connected to the marking box 41 through a spiral pipe 44.

[0054] Among them, the marking component 4 is used to automatically mark the detected defective area of the board for subsequent material replenishment and grinding operations. The marking component 4 includes a marking box 41. One end of the marking box 41 is fixedly connected to the mounting plate 21, which can store the marking agent in the device to ensure the continuity and safety of the material supply.

[0055] A first electric slide rail 42 is installed at the bottom end of the marking box 41. A first electric slider 43 is arranged inside the first electric slide rail 42. Driven by the first electric slide rail 42, the first electric slider 43 can make precise linear movement along the direction of the slide rail, and can accurately align with the defective area of the board to be marked according to the defect position signal output by the detection component 3 and the visual recognition block 35.

[0056] An electric spray head is installed at the bottom end of the first electric slider 43. The electric spray head is connected to the marking box 41 through a spiral tube 44. During the marking process, the electric spray head can be controlled to quantitatively and pointwise spray the marking agent from the marking box 41 onto the specified defective area of the board surface, realizing automatic and non-contact marking of the defect. The spiral tube 44 has flexibility and tensile properties, can adapt to the dynamic material supply requirements during the movement of the slider, and ensure the smooth and continuous supply of the marking agent.

[0057] The structure of this marking component is reasonably designed, can be linked with the detection component 3, and automatically complete the marking operation after defect detection. Compared with the traditional manual marking method, this marking component can significantly improve the automation level and marking accuracy of board defect treatment, reduce manual operation errors, improve production efficiency, and meet the large-scale and standardized production requirements of the modern intelligent furniture board processing field.

[0060] The magnetic extrusion block 56 is slidably connected to the extrusion groove 55, and the corresponding shape of the magnetic extrusion block 56 is set to be conical. A material replenishment spray head is installed at one end of the second electric slider 52, and the material replenishment spray head is connected to the storage tank through a conduit.

[0061] Among them, the filler assembly 5 is used to automatically fill and polish the detected and marked defective areas of the board, so as to improve the flatness and overall quality of the board surface. The filler assembly 5 includes a second electric slide rail 51. One end of the second electric slide rail 51 is fixedly connected to the mounting plate 21 to achieve the stable installation and spatial positioning of the assembly. A second electric slider 52 is arranged in the second electric slide rail 51. Driven by the second electric slide rail 51, the second electric slider 52 can make precise linear movement on the slide rail to adapt to the processing requirements of different defective areas.

[0062] A camera is installed on the second electric slider 52, which can monitor and locate the defective areas of the board in real time, providing precise visual guidance for the filling and polishing operations. An electric push rod is installed at the bottom end of the second electric slider 52.

Through the magnetic field generated by the electromagnet 54, the magnetic extrusion blocks 56 can be synchronously repelled or attracted, so that the plurality of magnetic extrusion blocks 56 act together on the board surface to form a plurality of evenly distributed filling depressions, which is conducive to the full penetration and firm combination of the filler.

[0064] In addition, a filling nozzle is installed at one end of the second electric slider 52.

[0071] Working principle:

[0072] The sheet material is first clamped and fixed and moved by the positioning guide rail 11 and the electric clamping plate on the processing base 1 to ensure an accurate and stable position during subsequent processing. Subsequently, the pretreatment component 2 performs pretreatment on the sheet material. Specifically, the detection component 3 on the mounting plate 21 is driven by the motor 33, and through the reciprocating lead screw 32 and the moving block 34, it realizes the adaptive detection of sheet materials with different thicknesses. The visual recognition block 35 and the detection strip 36 on the moving block 34 cooperate to utilize the mechanical-magnetic-optical linkage response of the color-changing functional layer and the internal magnetic strip to perform highly sensitive detection on the surface and near-surface defects of the sheet material, and accurately obtain the defect position and type through the visual recognition block 35. The detection results are transmitted to the marking component 4 in real time. The marking component 4 controls the electric spray head through the first electric slide rail 42 and the first electric slider 43, and automatically sprays the marking agent on the corresponding area according to the defect information to complete the accurate marking of the defect area. The feeding link is completed by the filling component 5. The second electric slide rail 51 drives the second electric slider 52 to automatically position in the marking area. The camera monitors the defect position in real time, and the feeding spray head accurately sprays the feeding agent according to the feedback. At the same time, the grinding ball 53 is driven by the electric push rod and the servo motor to finely grind and compact the feeding area. The magnetic extrusion block 56 cooperates under the action of the electromagnet 54 to form a depression to facilitate the penetration and adhesion of the feeding agent. After all the pretreatment is completed, the sheet material enters the grinding component 6 composed of the bracket 64, the grinding block 61, the hydraulic rod, the slider 62, the rotating block 63 and the electric grinding roller 65. The front and back sides of the sheet material are synchronously and automatically adjusted and finely ground evenly and efficiently by the symmetrically arranged grinding blocks 61 and multiple groups of electric grinding rollers 65. During the whole process, each module is closely linked through the central control system, realizing the full-process automation and intelligent operation of the sheet material from defect detection, automatic marking, accurate feeding to high-quality grinding, greatly improving the processing efficiency, repair accuracy and surface quality of the sheet material.
