Description

Technical Field

[0001] The present invention relates to the technical field of artificial marble surface repair, and specifically provides a construction process and grinding equipment for artificial marble surface repair based on AI technology. Background Art

[0002] Generally, artificial marble is composed of resin (20 - 30%), quartz powder (60 - 70%), pigments and adhesives (epoxy resin / polyurethane). Different ratios result in different hardnesses (Mohs hardness 4 - 7). When repairing the marble surface, it is necessary to polish its surface. Traditional polishing tools are likely to cause resin softening or quartz particle shedding. Therefore, special grinding equipment is required to grind the artificial marble surface.

[0003] Currently, manufacturers in the building materials industry have certain requirements for the surface of artificial marble after repair, such as requiring the glossiness ≥ 90 GU (60° incident angle) and the difference from the original surface ≤ 5%, etc., thus posing higher requirements for the grinding equipment.

[0004] However, the current equipment on the market cannot guarantee the same grinding effect for marble plates of different sizes. Since most equipment uses a mechanical clamping method to fix the plates, it inevitably causes some fixing structures to block the marble plates. When the marble plates are relatively small, this defect will be further amplified, affecting the grinding effect. Therefore, a construction process and grinding equipment for artificial marble surface repair based on AI technology are proposed to solve the above problems. Summary of the Invention

[0011] Furthermore, the heights of the plurality of blocking parts decrease in sequence from far away from the threaded rod to close to the threaded rod. A rubber ring is fixed to the outer surface of each blocking head.

[0012] Furthermore, a stepped hole is formed in the bottom of each blocking head. Each support rod extends into the stepped hole and fits with the inner bottom wall of the stepped hole.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 to 3, A grinding device for repairing the surface of artificial marble based on AI technology in this embodiment includes a box body 1. A workbench 2 is fixed to the inner bottom wall of the box body 1. An adjusting mechanism 3 extending into the workbench 2 and capable of ensuring better adaptation of the workbench 2 to different marbles is provided on the inner bottom wall of the box body 1. Four support legs are fixed to the bottom of the workbench 2. The four support legs can increase the space at the bottom of the workbench 2, reserving sufficient space for the adjusting mechanism 3 and the vacuum assembly 4. The workbench 2 is fixed to the inner bottom wall of the box body 1 through the four support legs. A vacuum assembly 4 for improving the connection tightness between the marble and the workbench 2 is provided at the bottom of the box body 1. A grinding assembly 5 is provided on the inner right wall of the box body 1 above the workbench 2. A dust suction assembly 6 for effectively adsorbing dust is provided on the inner left wall of the box body 1. A detection device 7 is fixed to the inner top wall of the box body 1. A white light interferometer, an infrared thermal imager, and a processor are arranged in the detection device 7. Through multi-modal sensor fusion, the grinding contact state is detected in real time. The white light interferometer is a Zygo NewView 9000, which can collect 2000 surface topography data points per second. The infrared thermal imager is a FLIRA65. The processor is built-in with an AI algorithm. By using a convolutional neural network (CNN) to analyze and detect defects such as gaps and holes, and splitting the defects, such as when the depth of microcracks is less than 5 mm or there is structural breakage, etc. And a process parameter database is also set in the processor, which can specify a repair plan according to the defects in time. By judging the data results of the white light interferometer and the infrared thermal imager, the grinding assembly 5 is regulated to improve the grinding quality. An embedded AI chip is installed on the processor, with a computing power ≥ 4 TOPS, supporting TensorRT accelerated inference.

[0031] In addition, the adjusting mechanism 3 includes a driving motor 301 fixed to the inner bottom wall of the box body 1. The driving motor 301 can provide power for the continuous and stable rotation of the threaded rod 302. One end of the output shaft of the driving motor 301 is fixed with a threaded rod 302 penetrating the inner bottom wall of the workbench 2. A connecting plate 303 is threadedly connected to the outer surface of the threaded rod 302 and located inside the workbench 2. Two limiting seats 304 are fixed to the inner bottom wall of the workbench 2, respectively on the left and right sides of the connecting plate 303. The connecting plate 303 is limited by the limiting seats 304 to ensure stable height adjustment of the connecting plate 303, so that the blocking part 305 moves upward stably. A plurality of blocking parts 305 are provided on the top of the connecting plate 303.

[0032] It should be further noted that each blocking portion 305 includes a support rod 3051 fixed to the top of the connecting plate 303. A support spring 3052 is movably connected to the outer surface of each support rod 3051. When the blocking head 3053 at the highest position moves to the target area, the pressure will act on the support spring 3052 at this time, causing the support spring 3052 to compress. The top of each support spring 3052 abuts against a blocking head 3053. Each support rod 3051 extends into the blocking head 3053 and is movably connected to the blocking head 3053. The bottom of each support spring 3052 abuts against the connecting plate 303. The support rod 3051 can improve the stability of the blocking head 3053 and prevent the blocking head 3053 from shaking in the horizontal direction.

[0033] It can be known that a plurality of adsorption holes communicating with the inner cavity of the workbench 2 are formed in the top of the workbench 2. The marble is adsorbed through the adsorption holes to improve the stability during marble grinding and improve the grinding quality. The plurality of blocking heads 3053 are respectively adapted to the plurality of adsorption holes. When the blocking head 3053 moves into the adsorption hole, the blocking head 3053 will block the adsorption hole to prevent energy waste caused by the marble being too small to cover all the adsorption holes. T-shaped blocks are fixed to the left and right sides of the connecting plate 303. T-shaped grooves are formed in the opposite sides of the two limit seats 304. The two T-shaped blocks respectively extend into the two T-shaped grooves and are movably connected to the T-shaped grooves. The T-shaped blocks are limited by the T-shaped grooves, and finally the connecting plate 303 is limited by the T-shaped blocks. The heights of the plurality of blocking portions 305 decrease in sequence from far away from the threaded rod 302 to close to the threaded rod 302. A rubber ring is fixed to the outer surface of each blocking head 3053, and the rubber ring can improve the airtightness.

[0034] In addition, a stepped hole is formed in the bottom of each blocking head 3053. Each support rod 3051 extends into the stepped hole and fits with the inner bottom wall of the stepped hole. When the blocking head 3053 at the highest position enters the adsorption hole, since the connecting plate 303 is still moving upward, the support rod 3051 is also forced to move upward at this time, and the stepped hole can provide enough space for the support rod 3051 to move upward. Each support rod 3051 is movably connected to the stepped hole. An air vent hole penetrating the connecting plate 303 is formed in each connecting plate 303. The air vent hole can ensure that the adsorption force of the vacuum assembly 4 is smoothly transmitted to the adsorption hole to realize the stable adsorption of the marble slab. A sealing bearing is fixed to the outer surface of the threaded rod 302, and the sealing bearing can improve the airtightness between the threaded rod 302 and the bottom wall of the workbench 2. The threaded rod 302 is rotatably connected to the bottom wall of the workbench 2 through the sealing bearing.

[0035] In this embodiment, the driving motor 301 drives the threaded rod 302 to rotate, further driving the blocking part 305 on the connecting plate 303 to move upward stably. Since the heights of the blocking parts 305 are different, the adsorption holes will be blocked in stages, so as to ensure that the unblocked adsorption holes are all located below the marble slab, ensuring the adsorption effect and reducing energy waste at the same time.

[0036] Please refer to again Figure 1 、 Figure 4 and Figure 5 For the sake of ensuring the stable progress of grinding, the vacuum assembly 4 in this embodiment includes an air suction pipe 401 fixedly communicated with the bottom of the workbench 2. The inner bottom wall of the box body 1 is fixed with an air extraction pump 402. The air extraction pump 402 can provide a reliable and stable adsorption force for the vacuum assembly 4. The right side of the air extraction pump 402 is fixedly communicated with the air suction pipe 401, and the left side of the air extraction pump 402 is fixedly communicated with an exhaust pipe 403 penetrating through the left side wall of the box body 1.

[0037] In addition, the grinding assembly 5 includes a robotic arm 501 fixed to the right side wall of the box body 1. The robotic arm 501 is a six-axis robotic arm, and a dry ice spraying module is also mounted on the robotic arm 501. Through AI path planning, it is ensured that the defective area is covered 100%. The output end of the robotic arm 501 is fixed with a clamping joint 502. The bottom of the clamping joint 502 is threadedly connected with a grinding disc 503. This structure facilitates the replacement of different grinding discs 503. The grinding discs 503 include diamond electroplated grinding discs with 80 - 400 meshes for rough cutting of adhesive protrusions, ceramic fiber sand discs with 800 - 1500 meshes for fine grinding of resin - quartz substrates, and polyurethane polishing wheels containing 3μm diamond micropowder for final polishing to a mirror effect. The left side of the clamping joint 502 abuts against a pin 504 penetrating through the clamping joint 502 and the grinding disc 503. The outer surface of the pin 504 is threadedly connected with a nut located on the right side of the clamping joint 502. A force feedback sensor is also installed at the fixing place of the robotic arm (501) and the clamping joint (502), which can feedback the pressure in real time and cooperate with the AI algorithm to achieve dynamic adjustment.

[0038] In addition, the dust suction assembly 6 includes a dust suction pump 601 fixed to the left inner wall of the box body 1. The bottom of the dust suction pump 601 is fixedly communicated with a corrugated pipe. The corrugated pipe has good flexibility. When manually sucking dust from the marble slab, the corrugated pipe can provide enough space for the movement of the dust suction head. A clamping seat 603 is fixed to the left inner wall of the box body 1 and is located below the dust suction pump 601. The connection between the clamping seat 603 and the dust suction pipe 602 is made of plastic, and the plastic has deformable ability for movement, which facilitates the smooth removal of the dust suction pipe 602 from the clamping seat 603. The bottom of the corrugated pipe is fixedly communicated with a dust suction pipe 602 penetrating through the clamping seat 603. The left side of the dust suction pipe 602 is fixedly communicated with a dust suction head. The top of the dust suction pump 601 is fixedly communicated with a connecting pipe 604 penetrating through the inner top wall of the box body 1, and the other end of the connecting pipe 604 is fixedly communicated with a filtering device.

[0039] In this embodiment, a construction process for artificial marble surface repair based on AI technology includes the following process steps:

[0040] 1) In the pretreatment stage, a fluorescent developer is first sprayed on the surface of the artificial marble to enhance the edge contrast of the adhesive under 365nm ultraviolet light. Then, infrared thermal imaging is used to detect the invisible cracks inside and a repair map is generated simultaneously.

[0041] 2) Grinding stage: A layered progressive strategy is adopted in the grinding stage. First, an 80-mesh grinding wheel is used to grind the marble surface to remove 90% of the adhesive residue. Then a 1500-mesh sandpaper is used to trim the surface roughness of the artificial marble to ±0.1mm. Finally, a 3μm polishing wheel is used to reduce the surface roughness of the marble to 0.05μm.

[0042] 3) In the post-processing quality inspection stage, a white light interferometer is used to scan the marble surface morphology to generate a color difference map, and then a hydrophobic coating is sprayed with a contact angle of >110° to improve the anti-fouling performance.

[0043] In this embodiment, the fluorescent developer contains SiO 2 @CdSe quantum dots, the hydrophobic coating is a fluorinated silane nano-solution. Using this process, the standard deviation of the adhesive residue height can be reduced from 0.23mm manually to 0.03mm, and the gloss difference between the repair area and the original surface can be reduced from 12.7% to 2.3%.

[0044] It can be understood that the front of the box 1 is hinged with a movable door, and an observation window is embedded in the movable door. A control computer is fixed to the back of the box 1, and stable control of the device is achieved through the control computer. This equipment achieves a marble surface gloss greater than or equal to 105GU by cooperating with the AI ​​algorithm.

[0045] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0046] The working principle of the above embodiment is:

[0047] First, place the marble slab on the top of the workbench 2, and then start the driving motor 301 to cause the threaded rod 302 to rotate. Due to the limiting effect of the limiting seat 304 on the connecting plate 303, the connecting plate 303 will move upward under the drive of the threaded rod 302. Since the heights of the multiple blocking parts 305 are different, during the upward movement of the connecting plate 303, the blocking head 3053 at a higher position will first block the adsorption holes until the remaining adsorption holes are all below the marble slab. After stopping the driving motor 301, turn on the vacuum assembly 4 to perform vacuum adsorption on the slab to achieve fixation, and then start the robotic arm 501, the dust suction pump 601, and the detection device 7 to grind the marble surface. During the grinding process, the dust is discharged to the filtering device through the dust suction pipe 602, the dust suction pump 601, and the connecting pipe 604. The detection device 7 will continuously detect the grinding condition of the marble surface to ensure the grinding quality.

[0048] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
