Description

Technical Field

[0001] This invention relates to the field of kitchenware processing technology, specifically to a surface treatment device for processing stainless steel kitchenware. Background Technology

[0002] Stainless steel countertops are a core component of kitchenware widely used in both commercial and home kitchens within the catering industry. Leveraging the natural advantages of high-quality stainless steel, they possess core characteristics such as corrosion resistance, high-temperature resistance, impact resistance, and easy cleaning. They effectively resist the corrosive effects of oil stains and acidic / alkaline cleaning agents in the kitchen environment, while withstanding direct contact with high-temperature cookware without easily deforming or damaging. Their simple and elegant appearance complements various décor styles. Furthermore, the material is environmentally friendly and non-toxic, meeting food contact safety standards. They have a long service life and low maintenance costs, making them particularly suitable for high-frequency use scenarios with stringent hygiene requirements. They are an ideal countertop choice that balances practicality and safety. Surface treatment during the processing of stainless steel countertops is key to enhancing their performance and aesthetics. The core purpose of this process is to enhance surface corrosion resistance, optimize appearance and texture, and improve user experience. Common surface treatment methods include brushing, polishing, and passivation. Brushing creates a uniform filamentous texture on the countertop surface, which not only reduces scratches during use but also creates a simple and delicate visual effect. Polishing uses fine grinding to give the surface a mirror or matte finish, enhancing aesthetics and further improving surface smoothness for easier cleaning. Passivation uses chemical methods to form a dense oxide protective film on the surface, significantly improving the countertop's corrosion resistance, extending its service life, and ensuring stability and reliability in kitchen environments where the countertop is in long-term contact with water, oil, and acidic or alkaline substances. In the existing technical field, current surface treatment technologies for stainless steel kitchenware processing suffer from limited processing adaptability. They can only process single structures such as planes or simple arcs. When dealing with complex multi-structure kitchenware, multiple changes in processing equipment and processes are required, which not only increases equipment investment costs but also leads to longer processing cycles and poor surface quality consistency. There is a drawback that it is difficult to balance processing precision and efficiency. Furthermore, traditional fine processing technologies rely heavily on manual operation, which is inefficient and prone to large errors. On the other hand, large-area processing technologies cannot guarantee the precision of local areas, especially in complex areas such as hemispherical ends and transition rounded corners, where over-grinding or insufficient grinding is likely to occur.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. The third motor drives the pulley in the transmission belt at the top of its rotating end to rotate. Under the rotation of the transmission belt and the pulley on the other side, the connecting shaft drives the grinding wheel to rotate. The grinding wheel relies on the high-speed rotation of its own side wall to perform grinding and polishing operations on the side wall surface of the workpiece. The second motor drives the box-shaped outer shell to rotate 90 degrees counterclockwise inside the U-shaped seat, so that the box-shaped outer shell rotates from vertical downward to horizontal, so that the grinding wheel relies on the high-speed rotation of its own side wall to perform fine grinding and polishing operations on the designated position on the upper surface of the workpiece. The three fourth motors on the sides drive the first grinding disc at its rotating end to rotate at high speed. Relying on the rotation of the lower surface of the first grinding disc, grinding and polishing is performed to achieve a large-area surface treatment operation on the flat surface of the workpiece.

[0011] 2. The first rotation module drives the first angle adjustment module to rotate clockwise or counterclockwise to a specified angle position. The first angle adjustment module drives the mounting bracket to rotate clockwise or counterclockwise to a specified tilt angle position. The first micro motors on both sides drive the first slide rails at their corresponding positions to swing clockwise or counterclockwise. The first slide rails on the upper and lower sides drive the first limit sliders at their corresponding positions to move along their own internal arc. Since the upper and lower first limit sliders are connected to each other, they cooperate to drive the lower fixed frame to drive the electric polishing disc. The electric polishing disc moves spirally around the vertical axis of the hemispherical structure, starting from the apex of the spherical structure. The swing amplitude of the first slide rails at their corresponding positions is adjusted by the first micro motors on both sides. With the cooperation of the first limit sliders on the upper and lower sides, the circumferential outer diameter of the electric polishing disc is adjusted. The motor inside the electric polishing disc drives the polishing disc to rotate, so as to achieve polishing and grinding of the hemispherical surface.

[0012] 3. The second rotation module drives the first angle adjustment module to rotate clockwise or counterclockwise to a specified angle position. The second angle adjustment module drives the second mounting plate to rotate clockwise or counterclockwise to a specified tilt angle position, so that the second grinding disc under the second mounting plate contacts the workpiece surface to be processed. The fifth motor drives one side of the transmission gear set to rotate, and under the transmission of the other side of the transmission gear set, drives the second grinding disc to rotate, so that the second grinding disc polishes the workpiece surface. The two second micro motors drive the gears in the corresponding bevel gear sets to rotate clockwise or counterclockwise respectively, and the gears in the other side of the two bevel gear sets rotate clockwise or counterclockwise respectively. The threaded rod at the corresponding position is driven to rotate. Under the rotational force of the threaded rod at the corresponding position, the toothed blocks on both sides move clockwise or counterclockwise along the arc-shaped inner cavity of the arc-shaped insert at the corresponding position. With the cooperation of the threaded rod on the other side, the second slide frame at the corresponding position moves arc-shaped to the left and right and forward and backward respectively. The second slide frames on both sides drive the third slide frame on their inner side to move along their own inner arc. Since the upper and lower third slide frames are connected to each other, the upper and lower third slide frames cooperate to drive the lower second shell to drive the second grinding disc, so that the second grinding disc moves back and forth along the outer arc of the workpiece to achieve the polishing and grinding treatment of the arc-shaped surface of the outer wall of the workpiece.

[0013] This enables highly adaptable processing of various structures, eliminating the need for frequent switching of processing equipment or adjustment of core parameters. It can accurately match the processing requirements of different surface structures such as planes, arcs, and hemispheres, greatly improving processing flexibility and versatility, and effectively avoiding grinding dead corners and quality defects in the corners and ends of traditional processing.

[0024] The specific tasks are as follows: Step 1: The operator issues a preset start command through control cabinet 1, simultaneously activating the electric sealing shell 2, the ground rail moving platform 3, the first motor 45, the auxiliary fixing module 43, and the air pump 46. After the command is executed, the sealing door of the electric sealing shell 2 opens, and the moving end of the ground rail moving platform 3 moves outward along the track to the safe loading area outside the electric sealing shell 2. With the help of external handling equipment, the operator places the large stainless steel kitchenware to be processed on the surface of the support shell 47 of the workpiece fixing mechanism 4. The first motor 45 drives the screw of the double-ended screw assembly 44 to rotate. Through the meshing transmission between the screw nut and the screw inside the double-ended screw assembly 44, the two clamping frames 42 are driven to move inward synchronously. The system moves to achieve clamping and positioning from the front and rear sides of the bottom of the workpiece's outer surface. The two sets of auxiliary fixing modules 43 start synchronously and work together with the clamping frame 42 through pressing or contact to further fix the side of the workpiece and prevent it from shaking. In addition, the air pump 46 supplies air to several vacuum suction cups 48 on the support shell 47 through the pipeline, so that the surface of the vacuum suction cups 48 generates vacuum suction force to adsorb and fix the workpiece from the bottom, forming a double fixing structure of side clamping and bottom suction. After fixing, the ground rail moving platform 3 retracts along the rail into the electric sealing shell 2, the sealing door inside the electric sealing shell 2 closes, and the dust purification equipment inside the electric sealing shell 2 starts to create a clean processing environment in advance to avoid the spread of grinding dust. Step 2: The operator starts the preset processing program through the control cabinet 1. The system will automatically match the corresponding fine processing parts 6, large-area processing parts 7, spherical processing parts 8 and arc processing parts 9 according to the specific structure of the workpiece to be processed, such as the upper surface, side wall, arc or hemispherical end. It will also drive the walking platform 52, the double-end moving module 53 and the lifting module 54 to complete the positioning adjustment in the three-axis direction. The walking platform 52 moves horizontally along the fixed track frame 51 on the front and rear sides inside the electric sealing shell 2, driving the entire set of processing parts to the approximate processing area of ​​the workpiece. The two double-end moving modules 53 on the left and right drive their own moving ends to move in the front and rear direction to achieve precise fine adjustment of the processing parts in the front and rear direction. The corresponding lifting module 54 is activated to drive the fine processing parts 6, large-area processing parts 7, spherical processing parts 8 or arc processing parts 9 below to move up and down until they reach the height position matching the surface of the workpiece to be processed, thus completing the three-axis collaborative positioning and ensuring processing accuracy. Step 3: When high-precision grinding and polishing of a local area of ​​the workpiece surface is required, the system uses the coordinated movement of the three-axis module to precisely move the fine machining component 6 to the designated machining position. Subsequently, the control cabinet 1 issues a command to start the third motor 66 and the second motor 63. The third motor 66 drives the pulley at its rotating end to rotate, and through the transmission belt 67, drives the connecting shaft 65 to rotate synchronously, thereby driving the grinding wheel 64 inside the box-type housing 62 to rotate at high speed. At this time, the grinding wheel 64 is in a vertical state, and relies on the high-speed rotation of its side wall to perform fine grinding and polishing on the side wall surface of the workpiece, removing burrs, scratches and other defects. If it is necessary to process the top plane of the upper surface of the workpiece, the second motor 66 drives the box-type housing 62 to rotate 90 degrees counterclockwise inside the U-shaped seat 61, so that the box-type housing 62 changes from a vertical state to a horizontal state. The side wall of the grinding wheel 64 then turns to the horizontal direction, and continues to complete the fine machining of the designated area of ​​the upper surface of the workpiece through high-speed rotation, realizing the rapid switching of the machining angle of the side wall and the upper surface. Step 4: When a large-scale surface treatment operation is required on the workpiece surface, the corresponding position walking platform 52, double-end moving module 53 and lifting module 54 cooperate to move in three-axis direction, so that the large-scale processing part 7 is moved to the designated position. The preset program inside the control cabinet 1 controls the three fourth motors 73 to start synchronously. Each fourth motor 73 drives the first grinding disc 74 at the bottom of its rotating end to rotate at high speed. The three first grinding discs 74 can grind and polish a large area of ​​flat surface at the same time. Step 5: When the hemispherical end of the workpiece needs to be ground and polished, the spherical processing component 8 is moved to the corresponding position. The control cabinet 1 simultaneously starts the first rotation module 81, the first angle adjustment module 82, the first micro motor 85, and the electric grinding disc 88 to achieve full coverage processing of the hemispherical surface. The first rotation module 81 drives the first angle adjustment module 82 to rotate clockwise or counterclockwise in the horizontal direction. The first angle adjustment module 82 then drives the mounting bracket 83 to rotate in the vertical direction. Through two angle adjustments, the electric grinding disc 88 is ensured to be aligned with the processing start position of the hemispherical end. The two first micro motors 85 drive the corresponding arc-shaped first slide rail bracket 84 to swing, and the upper and lower crosses intersect. The first sliding frame 84 arranged in a fork drives the first limiting slider 86 on its inner side to move along an arc-shaped trajectory. Since the two first limiting sliders 86 are connected to each other, they work together to drive the fixed frame 87 below to drive the electric polishing disc 88. Starting from the apex of the hemisphere, it makes a spiral circumferential motion around the vertical axis of the hemisphere. By adjusting the driving amplitude of the first micro motor 85, the swing angle of the first sliding frame 84 can be changed, thereby realizing the adaptive adjustment of the outer diameter of the circumferential motion of the electric polishing disc 88, achieving the purpose of full coverage polishing of hemispheres of different sizes. At the same time, the motor inside the electric polishing disc 88 drives the polishing disc to rotate at high speed to complete the polishing treatment of the hemisphere, ensuring that the surface is smooth and without dead corners. Step 6: When machining the curved surface of the workpiece, control cabinet 1 activates the second rotation module 91, the second angle adjustment module 92, the fifth motor 915, and the second micro motor 99. The second rotation module 91 drives the second angle adjustment module 92 to rotate horizontally, and the second angle adjustment module 92 then drives the second mounting plate 93 to rotate vertically, so that the second grinding disc 914 below precisely fits the curved surface of the workpiece to be machined. The fifth motor 915 drives one side gear of the transmission gear set 916 to rotate, and through the meshing transmission gear set 916, the second grinding disc 914 is driven to rotate at high speed, starting the grinding operation. The two second micro motors 99 drive the corresponding... The bevel gear set 910 rotates, which drives the threaded rod 98 to rotate. The threaded rod 98 meshes with the toothed block 96, driving the toothed block 96 to move the arc-shaped insert 95 along the arc-shaped slide seat 94. The arc-shaped inserts 95 on both sides drive the two cross-shaped arc-shaped second slide frames 911 to move in arc-shaped motion in the front-back and left-right directions, thereby driving the inner third slide frame 912 to move along the arc-shaped trajectory. Since the two third slide frames 912 are connected to each other, they work together to drive the lower second outer shell 913 to drive the second grinding disc 914 to move smoothly back and forth along the arc-shaped surface of the workpiece, achieving full coverage and uniform grinding and polishing of the arc-shaped area.
