Description

Technical Field

[0001] This invention belongs to the field of sand core manufacturing technology, specifically a sand core surface coating robot. Background Technology

[0002] Sand cores are materials used to manufacture mold cores in casting production. They are composed of casting sand, molding sand binder, etc. In order to improve the surface finish of the product, sand cores generally need to be sprayed or dipped in paint and then dried or air-dried after manufacturing. Generally, alcohol paint is used for spraying to shorten the process, increase evaporation, and ensure that it enters the sand core quickly, thereby shortening the production cycle.

[0003] The automatic spraying equipment used in the prior art is usually located directly above the sand core, and the paint sprayed from the spray gun nozzle spreads outwards from top to bottom. This can only spray the surface of the sand core, but since the sand core has a certain thickness, it is impossible to spray the sides of the sand core. Summary of the Invention

An electric motor is installed at the bottom of the inner wall of the mixing tank; A stirring rod is installed on the outer wall of the motor. The stirring rod is used to stir the coating and prevent the coating from separating and settling to the bottom.

[0009] Furthermore, the stirring mechanism also includes: A fixing plate is provided on the upper part of the inner wall of the mixing tank, and a fan-shaped hole is provided in the middle of the fixing plate; The first scraper is symmetrically arranged at the bottom of the fixed plate, and the top of the first scraper is rotatably connected to the bottom of the fixed plate. An elastic rod is symmetrically arranged on the inner wall of the mixing tank, and one end of the elastic rod is in contact with the outer wall of the first scraper.

[0010] Furthermore, the stirring mechanism also includes: The second scraper is disposed on the bottom of the fixed plate on the side away from the first scraper; A movable frame is disposed above a fixed plate, the outer wall of the movable frame is fitted with the inner wall of the fixed plate, and the bottom of the movable frame is in contact with the outer wall of the first scraper. A spring is disposed at the bottom of the movable frame, and the bottom of the spring is connected to the top of the fixed plate.

[0011] Furthermore, the protective component includes: A support rod, which is mounted at the bottom of the robotic arm; A protective ring is installed at the end of the support rod away from the robotic arm; The nozzle is located at the bottom of the robotic arm, and the inner wall of the protective ring is fitted with the outer wall of the nozzle. The suction pipes are symmetrically arranged on the outer wall of the protective ring; A collection trough is located at the bottom of the protective ring.

[0012] Furthermore, the application component includes: The first telescopic column is installed at the bottom of the robotic arm; A baffle is installed at the end of the first telescopic column away from the robotic arm; An irregularly shaped brush is installed on the side of the baffle away from the first telescopic column.

[0013] Furthermore, the support component includes: An arc-shaped plate, the bottom of which is rotatably connected to the outer wall of the movable block; A telescopic rod is installed at the end of the arc-shaped plate away from the moving block; A limiting plate is installed at the end of the telescopic rod away from the arc-shaped plate; The second telescopic column is installed on the side of the limiting plate near the brake disc core, and the outer wall of the second telescopic column is sleeved with the inner wall of the limiting plate. An airbag is installed at one end of the second telescopic column near the brake disc core, and the outer wall of the airbag is in contact with the outer wall of the limiting plate.

[0014] The beneficial effects of this invention are as follows: 1. This invention, by setting up a spraying mechanism, after spraying on both sides, the coating component is lifted upward by the mechanical arm. The fixing mechanism, in conjunction with the spraying mechanism, aligns the cylindrical surface of the brake disc core with the protective component, so that the entire brake disc core is sprayed. There is no need for manual handling of the brake disc core, and the paint can be sprayed on it from all directions. In particular, the gaps and sides of the brake disc core can also be sprayed and covered, improving the automation of the equipment and the coverage of the paint on the surface of the brake disc core.

[0015] 2. This invention, by setting a fixing mechanism, aligns the circular surface of the brake disc core with the spraying mechanism. The roller rotates, causing the brake disc core to roll around the support component, enabling the spraying mechanism to spray the circular surface of the brake disc core. This keeps the brake disc core stable during the spraying process and allows for flexible and uniform spraying of all surfaces without the need for manual flipping. This reduces the risk of scratches and sand shedding on the surface of the brake disc core, maintaining its surface flatness.

[0016] 3. This invention, by setting up a protective component, positions the nozzle at the center of the brake disc core radius, rather than the center, so that the area sprayed by the nozzle corresponds to the area of ​​the brake disc ring. As the roller rotates the brake disc core for spraying, it avoids the problem of uneven coating caused by large distance deviations between the center and edges of the brake disc when spraying directly from the center. This ensures a smaller difference in distance between the nozzle and one side of the brake disc core, achieving uniform coating. The protective ring collects and blocks atomized gases during the spraying process, reducing the spraying area, minimizing contact between the paint and external elements, and reducing paint waste.

[0017] 4. This invention, by setting up a stirring mechanism and a coating component, scrapes off excess paint from the shaped brush, preventing the paint picked up by the brush from dripping or being squeezed out during coating. This prevents excess paint from falling onto the workbench or adhering to the surface of the brake disc core, causing uneven coating and affecting the quality of the brake disc core coating. Driven by a robotic arm, the shaped brush is inserted into the gaps of the brake disc core to apply the paint, ensuring that even the gaps of the brake disc core are coated evenly, avoiding dead corners and gaps that cannot be reached by spraying.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a sand core surface coating robot, which is described below.

[0022] include: Machine 1, with lifting columns 2 symmetrically arranged on the top of the machine 1; Fixed rod 3, with both ends of fixed rod 3 installed on the top of lifting column 2. The inner wall of the spraying mechanism 4 is slidably connected to the outer wall of the fixing rod 3; The sand core surface coating robot also includes: Fixing mechanism 5 is located at the central axis of machine base 1, and the bottom of fixing mechanism 5 is rotatably connected to the bottom of the inner wall of machine base 1. The mixing mechanism 6 is located on the top of the machine base 1, near the side of the coating component 404.

[0023] During operation, the worker places the brake disc core 506 into the fixing mechanism 5, which then vertically fixes the core. The spraying mechanism 4 moves to the center on the fixing rod 3 and sprays paint onto one side of the brake disc core 506. At the same time, the paint is applied to the inner wall of the brake disc core 506, ensuring that the paint adheres evenly to the surface of the brake disc core 506. The stirring mechanism 6, in conjunction with the spraying mechanism 4, stirs and mixes the paint during application to prevent uneven distribution.

[0024] The spraying mechanism 4 includes: Slider 401, the inner wall of slider 401 is slidably connected to the outer wall of fixed rod 3; Robotic arm 402 is symmetrically arranged on the inner wall of slider 401; Protective component 403 is disposed at the bottom of robotic arm 402; The application component 404 is located at the bottom of the robotic arm 402, and the protective component 403 and the application component 404 are respectively located below the two robotic arms 402.

[0025] After the brake disc core 506 is vertically fixed, the slider 401 moves on the fixing rod 3 to directly above the brake disc core 506, causing the robotic arm 402 to move the protective component 403 to one side perpendicular to the brake disc core 506. This allows for spraying one side of the brake disc core 506. The protective component 403 can suction the paint to reduce paint spillage. Simultaneously, the coating component 404, driven by the robotic arm 402, extends into the mixing mechanism 6 to pick up paint, then inserts it into the gaps of the brake disc core 506 to coat the gaps. The entire coated side is then coated. After completion, the fixing mechanism 5 rotates 180 degrees to spray and coat the other side. After the spraying of both sides is completed, the coating component 404 is lifted upward by the mechanical arm 402. The fixing mechanism 5, in conjunction with the spraying mechanism 4, aligns the cylindrical surface of the brake disc core 506 with the protective component 403, so that the entire brake disc core 506 is sprayed. The brake disc core 506 can be coated from all directions without the need for manual handling. In particular, the gaps and sides of the brake disc core 506 can also be coated and covered, improving the automation of the equipment and the coverage of the coating on the surface of the brake disc core 506.

[0026] Fixed mechanism 5 includes: Turntable 501, the bottom of turntable 501 is rotatably connected to the bottom of the inner wall of machine base 1; Movable block 502 is symmetrically arranged on the top of turntable 501, and the bottom of movable block 502 is slidably connected to the top of turntable 501. Brake disc sand core 506 is located in the middle of the two moving blocks 502.

[0027] The fixed mechanism 5 also includes: Mounting plate 503, the outer wall of mounting plate 503 is rotatably connected to the inner wall of movable block 502; Rollers 504 are symmetrically arranged on both sides of the mounting plate 503, and the outer wall of the rollers 504 is rotatably connected to the outer wall of the mounting plate 503. Support component 505, the outer wall of support component 505 is rotatably connected to the outer wall of movable block 502, and the end of support component 505 away from movable block 502 is sleeved with the inner wall of brake disc sand core 506.

[0028] Initially, the worker places the brake disc core 506 vertically in the middle of the moving blocks 502, bringing the blocks closer together. The rollers 504 on the mounting plate 503 contact the edge of the brake disc core 506. Then, the support assembly 505 on one side rotates to the center hole of the brake disc core 506 and is inserted. Inflation then supports the inner wall of the brake disc core 506, allowing it to rotate under the action of the rollers 504. After the spraying mechanism 4 sprays one side of the brake disc core 506, the turntable 501 rotates 18... Align the other side with the spraying mechanism 4 at 0 degrees. After the two sides are sprayed, the turntable 501 rotates 90 degrees to align the circular surface of the brake disc core 506 with the spraying mechanism 4. The roller 504 rotates, causing the brake disc core 506 to roll around the support component 505, so that the spraying mechanism 4 can spray the circular surface of the brake disc core 506. This keeps the brake disc core 506 stable during the spraying process and flexibly cooperates with the spraying mechanism 4 to spray each surface evenly. There is no need for manual flipping, which reduces the risk of scratches and sand loss on the surface of the brake disc core 506 and maintains the flatness of the surface of the brake disc core 506.

[0029] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the protective component 403 includes: Support rod 4031 is installed at the bottom of robotic arm 402; Protective ring 4032 is installed on the end of support rod 4031 away from robotic arm 402; Nozzle 4034 is located at the bottom of robotic arm 402, and the inner wall of protective ring 4032 is fitted with the outer wall of nozzle 4034. The suction pipe 4033 is symmetrically arranged on the outer wall of the protective ring 4032. The suction pipe 4033 is connected to a suction device, which is turned on to collect gas during spraying. The collection tank 4035 is located at the bottom of the protective ring 4032 to collect the paint that drips from the nozzle 4034 during spraying, preventing it from dripping onto the workbench and the surface of the brake disc core 506.

[0030] During spraying, driven by the robotic arm 402, the nozzle 4034 is positioned on one side of the plane of the brake disc core 506. The nozzle 4034 is located in the middle of the radius of the brake disc core 506, rather than at the center, so that the area sprayed by the nozzle 4034 corresponds to the area of ​​the brake disc ring. As the roller 504 rotates the brake disc core 506 for spraying, it avoids the problem of uneven coating caused by large distance deviations when spraying at the center of the brake disc, which is common when spraying directly at the center of the brake disc. This ensures that the distance between the nozzle 4034 and one side of the brake disc core 506 is small, achieving uniform coating of the brake disc core 506. The protective ring 4032 collects and blocks the atomized gas during the spraying process, reducing the spraying area, reducing contact between the outside and the coating, and reducing coating waste.

[0031] The 404 application component includes: The first telescopic column 4041 is installed at the bottom of the robotic arm 402; Baffle 4042 is installed at the end of the first telescopic column 4041 away from the robotic arm 402; The irregularly shaped brush 4043 is installed on the side of the baffle 4042 away from the first telescopic column 4041. The irregularly shaped brush 4043 is fan-shaped and corresponds to the hole on the brake disc.

[0032] The stirring mechanism 6 includes: Mixing tank 601 is installed on the top of machine 1 near the side of coating component 404; Motor 602 is installed at the bottom of the inner wall of the mixing tank 601; A stirring rod 603 is installed on the outer wall of the motor 602. The stirring rod 603 is used to stir the coating and prevent the coating from separating and settling.

[0033] The stirring mechanism 6 also includes: The fixing plate 606 is located on the upper part of the inner wall of the mixing tank 601, and a fan-shaped hole is opened in the middle of the fixing plate 606. The first scraper 608 is symmetrically arranged at the bottom of the fixed plate 606. The top of the first scraper 608 is rotatably connected to the bottom of the fixed plate 606. The first scraper 608 and the second scraper 609 are arranged according to the edge of the fan-shaped hole on the fixed plate 606, so that when the coating component 404 is inserted and pulled out, it scrapes off the excess coating on its surface to prevent the coating from dripping and overflowing. Elastic rods 607 are symmetrically arranged on the inner wall of the mixing tank 601, and one end of the elastic rods 607 is in contact with the outer wall of the first scraper 608.

[0034] The stirring mechanism 6 also includes: The second scraper 609 is disposed on the bottom side of the fixed plate 606 away from the first scraper 608; The movable frame 604 is positioned above the fixed plate 606. The outer wall of the movable frame 604 is fitted with the inner wall of the fixed plate 606, and the bottom of the movable frame 604 is in contact with the outer wall of the first scraper 608. The movable frame 604 is made of elastic material. When the coating component 404 is inserted downward into the fan-shaped hole on the fixed plate 606, it pushes the first scraper 608 open. When the coating component 404 is taken out upward, it closes under the action of the elastic rod 607, scraping off the excess coating on the coating component 404. Spring 605 is located at the bottom of the movable frame 604, and the bottom of spring 605 is connected to the top of the fixed plate 606.

[0035] Initially, paint is loaded into the mixing tank 601. The motor 602 drives the stirring rod 603 to stir the paint, preventing it from settling and separating. During the spraying of the protective component 403, the robotic arm 402 on the other side drives the irregularly shaped brush 4043 on the first telescopic column 4041 to insert into the mixing tank 601. The end of the irregularly shaped brush 4043 is inserted into the fan-shaped hole on the fixing plate 606 to pick up the paint in the mixing tank 601. When moving downward, the baffle 4042 contacts the top of the moving frame 604, causing the moving frame 604 to move downward and push the first scraper 608 aside, allowing the irregularly shaped brush 4043 to make smooth contact with the paint. Then, driven by the spring 605, the moving frame 604 returns to its original position. Returning to its original position, the brush 4043 is lifted upwards by the robotic arm 402 and then closed by the elastic rod 607. This scrapes away excess paint from the brush 4043, preventing it from dripping or being squeezed out during application. This would prevent excess paint from falling onto the workbench or adhering to the surface of the brake disc core 506, causing uneven application and affecting the quality of the paint application. The robotic arm 402 then inserts the brush 4043 into the gaps of the brake disc core 506 to apply paint evenly, ensuring that the gaps are also coated and preventing dead zones that cannot be reached by spraying.

[0036] Support component 505 includes: Arc-shaped plate 5051, the bottom of which is rotatably connected to the outer wall of movable block 502; Telescopic rod 5052 is installed on the end of arc plate 5051 away from moving block 502; Limiting plate 5053 is installed at the end of telescopic rod 5052 away from arc plate 5051; The second telescopic column 5054 is installed on the side of the limiting plate 5053 near the brake disc sand core 506, and the outer wall of the second telescopic column 5054 is sleeved with the inner wall of the limiting plate 5053. Airbag 5055 is installed at one end of the second telescopic column 5054 near the brake disc sand core 506, and the outer wall of airbag 5055 is in contact with the outer wall of limit plate 5053.

[0037] After the brake disc core 506 is placed in the moving center, the arc-shaped plate 5051 on the side away from the protective component 403 rotates, so that the second telescopic column 5054 is located in the middle of the brake disc core 506. Then the second telescopic column 5054 extends, inserts the airbag 5055 into the central axis of the brake disc core 506, inflates the airbag 5055, and supports the central axis of the brake disc. With the auxiliary support of the roller 504, the brake disc is placed vertically. After one side is sprayed, the arc-shaped plate 5051 on the other side rotates and inserts into the brake disc core 506. The arc-shaped plate 5051 on the sprayed side is retracted, so that the arc-shaped plate 5051 on the side facing the protective component 403 is in a position away from the brake disc core 506, so that the flat surface of the brake disc core 506 is completely exposed in front of the protective component 403, which facilitates the uniform spraying of the brake disc core 506. There is no need for manual flipping, which consumes manpower and reduces the contact between personnel and spraying equipment, thus protecting the health of personnel.

[0038] The specific workflow is as follows: During operation, initially, the worker places the brake disc core 506 vertically in the middle of the moving blocks 502, bringing the moving blocks 502 closer together. The rollers 504 on the mounting plate 503 then contact the edge of the brake disc core 506. The support assembly 505 on one side rotates to the middle hole of the brake disc core 506 and is inserted. Subsequently, air is inflated to support the inner wall of the brake disc core 506, so that the edge of the brake disc core 506 contacts the rollers 504 under the action of the support assembly 505, and can rotate under the action of the rollers 504. After the brake disc core 506 is erected and fixed, the slider 401 moves on the fixing rod 3 to directly above the brake disc core 506, so that the robotic arm 402 drives the protective component 403 to be positioned on one side of the vertical brake disc core 506, and sprays one side of the brake disc core 506. The protective component 403 can perform air suction treatment on the paint to reduce paint spillage. At the same time as spraying, the coating component 404 is driven by the robotic arm 402 to extend into the mixing mechanism 6 to pick up the paint, and then inserts it into the gap of the brake disc core 506 to coat the gap of the brake disc core 506. After the spraying mechanism 4 sprays one side of the brake disc core 506, the turntable 501 rotates 180 degrees to align the other side with the spraying mechanism 4. After the two sides are sprayed, the turntable 501 rotates 90 degrees to align the circular surface of the brake disc core 506 with the spraying mechanism 4. The roller 504 rotates, causing the brake disc core 506 to roll around the support component 505, so that the spraying mechanism 4 can spray the circular surface of the brake disc core 506. During the spraying process of the protective component 403, the robotic arm 402 on the other side drives the irregularly shaped brush 4043 on the first telescopic column 4041 to first insert into the mixing tank 601, so that the end of the irregularly shaped brush 4043 is inserted into the fan-shaped hole on the fixed plate 606, and dips into the paint in the mixing tank 601. When moving downward, the baffle 4042 contacts the top of the moving frame 604, causing the moving frame 604 to move downward and push the first scraper 608 open, so that the irregularly shaped brush 4043 can make smooth contact with the paint. Then, driven by the spring 605, the moving frame 604 returns to its original position. When the robotic arm 402 drives the irregularly shaped brush 4043 to be taken out upward, it closes under the action of the elastic rod 607, scraping off the excess paint on the irregularly shaped brush 4043.
