Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment, and in particular relates to a spraying device for a surface coating of diamond synthetic core. Background Technology

[0002] As the superhard materials industry continues to increase its requirements for the precision and performance of diamond products, higher standards have been set for the surface treatment technology of diamond synthetic cores. A uniform and dense functional coating needs to be formed on the surface of the core, and the coating needs to completely cover the circumferential side, top and bottom surfaces of the core, all of which are key contact or stress surfaces in the synthesis process.

[0003] Chinese patent application CN219702380U discloses a coating spraying device, including a worktable, a support frame, a spraying component, and a support component. The support frame is fixed to the top of the worktable, the spraying component is located on the support frame, and the support component is fixed to the bottom of the worktable. A fixing component is disposed on the worktable and includes a placement component, a fastener, a positioning component, and an adjusting component. The placement component is disposed on the top of the worktable, the fastener is located at the bottom of the spraying component, the positioning component is disposed within the placement component, and the adjusting component is disposed within the positioning component. This utility model uses the spraying component to spray materials, and the fixing component is used to fix the materials, and can fix materials of different sizes and materials.

[0004] The above-mentioned device uses a fixed component to clamp the workpiece, which solves part of the problem of uniformity in circumferential spraying. However, it can only achieve side spraying and requires manual secondary flipping of the workpiece to process the top and bottom surfaces, increasing the operation steps. At the same time, the existing device lacks an effective paint stirring mechanism, and the paint is prone to particle sedimentation during the spraying process, which leads to nozzle blockage or uneven coating composition, thereby affecting the stability of the core column surface performance.

[0005] To address these issues, we provide a coating spraying device for the surface of diamond synthetic core posts. Utility Model Content

[0006] The purpose of this invention is to provide a coating spraying device for the surface of diamond synthetic cores. By combining a stirring spraying component and an adjustable positioning component, it solves the problem that existing spraying devices require manual secondary flipping of the workpiece and lack an effective coating stirring mechanism.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a coating spraying device for the surface of a diamond synthetic core, comprising a frame. A stirring spraying assembly is mounted on one side of the top of the frame, and an adjustable positioning assembly is mounted on the other side of the top of the frame. The adjustable positioning assembly includes a mounting frame, the top of which is fixedly connected to the frame. A servo motor is fixedly connected to the top of the mounting frame, and a turntable is fixedly connected to the output end of the servo motor. The top of the turntable extends through to the top of the frame, and a positioning seat is fixedly connected to the top of the turntable. The positioning seat has a core-mounting groove on its top, and an inverting mechanism is provided on one side of the positioning seat. The shape of the core-mounting groove is adapted to the outer contour of the diamond synthetic core, and a flexible protective pad is fitted to the inner wall, which can stably clamp the core and prevent the core from falling off. The wobbling during rotation prevents scratches on the core column surface from direct contact with the tank wall. After one side of the core column is coated, the inverting mechanism grips and flips it, maintaining the core column's axis stability during the flipping process and preventing it from falling or shifting position. A servo motor drives the turntable to rotate the core column at a uniform speed, avoiding uneven coating thickness on the circumferential surface due to uneven rotation speed. The inverting mechanism flips the core column without manual intervention, solving the problems of core column shifting and coating scratches that are easily caused by traditional manual flipping. It also ensures that the uncoated side of the core column aligns with the coated area, achieving full coverage of the top and bottom surfaces and the circumferential surface of the core column, eliminating coating dead corners, and meeting the requirements of diamond synthetic core columns for surface coating integrity.

[0009] The present invention is further configured such that the inverting mechanism includes a fixed frame, the bottom of which is fixedly connected to the frame, a first electric push rod is fixedly connected to the bottom of the inner cavity of the fixed frame, a second electric push rod is fixedly connected to the top of the first electric push rod, a drive motor is fixedly connected to one side of the second electric push rod, a connecting seat is fixedly connected to the output end of the drive motor, and pneumatic clamps are provided on both sides of the connecting seat. The first electric push rod can adjust the height direction, and can adjust the gripping position of the pneumatic clamp according to the height of the core column in the mounting slot. The second electric push rod moves horizontally, driving the pneumatic clamp to move closer to or away from the core column. The drive motor drives the connecting seat and the pneumatic clamp to achieve a 180° rotation, which, together with the pneumatic clamp, stably holds the core column, avoiding positioning deviation and coating scratches during manual flipping, and ensuring that the core column is reset to the spraying position after flipping.

[0010] The present invention is further configured such that the stirring spraying assembly includes a mixing tank, the bottom of which is fixedly connected to the frame, a connecting frame is provided on the top of the mixing tank, a variable frequency motor is fixedly connected to the top of the connecting frame, a stirring paddle is fixedly connected to the output end of the variable frequency motor, the bottom of the stirring paddle extends through the inner cavity of the mixing tank, and a spraying mechanism is provided on one side of the mixing tank. The variable frequency motor drives the stirring paddle to continuously stir in the mixing tank, effectively preventing the sedimentation of functional particles in the coating liquid, ensuring uniform composition of the coating liquid, and avoiding coating composition differences or nozzle clogging caused by uneven coating liquid concentration.

[0011] The present invention is further configured such that the spraying mechanism includes a support frame, the bottom of the support frame is fixedly connected to the frame, a fixed seat is fixedly connected to the surface of the support frame, a nozzle is movably connected to one side of the fixed seat via a rotating shaft, a rotary motor is fixedly connected to one side of the fixed seat, the output end of the rotary motor is fixedly connected to the nozzle, and the fixed seat is movably connected to the nozzle via the rotating shaft. In conjunction with the rotary motor driving the nozzle, the nozzle can be adjusted at multiple angles to ensure that the nozzle can spray the core column from the appropriate angle, thus ensuring the uniformity and integrity of the coating on the core column surface.

[0012] The present invention is further configured such that a connecting pipe is connected to the bottom of one side of the mixing tank, a pump body is connected to one side of the connecting pipe, a delivery pipe is connected to one side of the pump body, and the top of the delivery pipe is connected to the nozzle. The connecting pipe, pump body and delivery pipe are configured to provide a stable supply of coating liquid during the spraying process, ensuring that the amount of coating liquid supplied at the nozzle is uniform.

[0013] The present invention is further configured such that the top of the nozzle is connected to an air inlet pipe, the top of the air inlet pipe is connected to an external air pump, and the high-pressure gas generated by the external air pump enters the nozzle through the air inlet pipe and can be fully mixed with the coating liquid conveyed by the delivery pipe, so that the coating liquid forms fine and uniform atomized particles, and the atomized coating liquid particles can adhere more evenly to the surface of the core column.

[0014] The present invention is further configured such that a control cabinet is fixedly connected to one side of the surface of the frame, and a display screen is fixedly connected to the top of the surface of the control cabinet. The configuration of the control cabinet and the display screen improves the convenience of device operation and the controllability of process parameters.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses a servo motor to drive a turntable, which in turn drives the positioning seat and the core column in the mounting slot to make uniform circular motion. This ensures that the core column maintains a stable rotation during the spraying process, avoiding uneven coating thickness on the circumferential surface caused by unstable rotation. At the same time, the inverting mechanism realizes automatic flipping of the core column, which can complete the spraying operation on the other side of the core column without manual intervention. This not only effectively solves the problems of positioning deviation and coating scratches that are easy to occur when manually flipping the core column, but also ensures that the unsprayed side of the core column is aligned with the spraying area, achieving full coverage of the upper and lower end faces and the circumferential surface of the core column, eliminating spraying dead corners, and meeting the requirements of diamond synthetic core columns for the integrity of the surface coating.

[0017] 2. This utility model uses a variable frequency motor to drive a stirring paddle to continuously stir the coating liquid in the container, effectively preventing sedimentation during the spraying process and ensuring that the coating liquid composition remains uniform. This avoids problems such as uneven coating composition and nozzle clogging caused by coating liquid sedimentation. The nozzle device angle is adjustable, enabling spraying of the core column surface from multiple directions. Combined with the rotational movement of the core column, it can fully cover the circumferential surface, top surface, and bottom surface of the core column, ensuring that each surface of the core column can obtain a uniform coating, further meeting the stringent requirements of diamond synthetic core columns for surface coating uniformity.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model is a coating spraying device for the surface of diamond synthetic core, including a frame 1. A stirring spraying component 2 is provided on one side of the top of the frame 1, and an adjustable positioning component 3 is provided on the other side of the top of the frame 1. The adjustable positioning component 3 includes a mounting frame 31. The top of the mounting frame 31 is fixedly connected to the frame 1. A servo motor 32 is fixedly connected to the top of the mounting frame 31. A turntable 33 is fixedly connected to the output end of the servo motor 32. The top of the turntable 33 extends through to the top of the frame 1. A positioning seat 34 is fixedly connected to the top of the turntable 33. A core mounting groove 35 is opened on the top of the positioning seat 34. An inverting mechanism 36 is provided on one side of the positioning seat 34.

[0028] Specifically: The shape of the mounting groove 35 is adapted to the outer contour of the diamond synthetic mandrel, and the inner wall is fitted with a flexible protective pad, which can not only form a stable clamp for the mandrel and prevent the mandrel from shaking during rotation, but also prevent the surface of the mandrel from being scratched due to direct contact with the groove wall. After one side of the mandrel is coated, the inverting mechanism 36 realizes the grasping and flipping of the mandrel. During the flipping process, the axis of the mandrel is kept stable, and the mandrel is prevented from falling or shifting position when flipping. The servo motor 32 drives the turntable 33 to rotate the mandrel at a uniform speed, so as to avoid the difference in coating thickness on the circumferential surface due to uneven rotation speed. The inverting mechanism 36 completes the flipping of the mandrel without manual intervention. It not only solves the problems of mandrel shift and coating scratches that are easily caused by traditional manual flipping, but also ensures that the uncoated side of the mandrel is aligned with the coated area, realizing full coverage of the upper and lower end faces and the circumferential surface of the mandrel, eliminating coating dead corners, and meeting the requirements of diamond synthetic mandrel for surface coating integrity.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, the inverting mechanism 36 includes a fixed frame 361. The bottom of the fixed frame 361 is fixedly connected to the frame 1. A first electric push rod 362 is fixedly connected to the bottom of the inner cavity of the fixed frame 361. A second electric push rod 363 is fixedly connected to the top of the first electric push rod 362. A drive motor 364 is fixedly connected to one side of the second electric push rod 363. A connecting seat 365 is fixedly connected to the output end of the drive motor 364. Pneumatic clamps 366 are provided on both sides of the connecting seat 365. The stirring spraying assembly 2 includes a mixing tank 21. The bottom of the mixing tank 21 is fixedly connected to the frame 1. A connecting frame 22 is provided on the top of the mixing tank 21. A variable frequency motor 23 is fixedly connected to the top of the connecting frame 22. A stirring paddle 24 is fixedly connected to the output end of the variable frequency motor 23. The bottom of the stirring paddle 24 extends through the mixing tank 21. Inside the mixing tank 21, a spraying mechanism 25 is provided on one side. The spraying mechanism 25 includes a support frame 251. The bottom of the support frame 251 is fixedly connected to the frame 1. A fixed seat 252 is fixedly connected to the surface of the support frame 251. A nozzle 253 is movably connected to one side of the fixed seat 252 via a rotating shaft. A rotary motor 254 is fixedly connected to one side of the fixed seat 252. The output end of the rotary motor 254 is fixedly connected to the nozzle 253. A connecting pipe 4 is connected to the bottom of one side of the mixing tank 21. A pump body 5 is connected to one side of the connecting pipe 4. A conveying pipe 6 is connected to one side of the pump body 5. The top of the conveying pipe 6 is connected to the nozzle 253. An air inlet pipe 7 is connected to the top of the nozzle 253. The top of the air inlet pipe 7 is connected to an external air pump. A control cabinet 8 is fixedly connected to one side of the surface of the frame 1. A display screen 9 is fixedly connected to the top of the surface of the control cabinet 8.

[0031] Specifically: The first electric push rod 362 adjusts the height, allowing the pneumatic clamp 366 to grip the core column according to its height within the mounting slot 35. The second electric push rod 363 moves horizontally, moving the pneumatic clamp 366 closer to or further away from the core column. The drive motor 364 drives the connecting seat 365 and the pneumatic clamp 366 to rotate 180°, ensuring stable gripping of the core column and preventing positioning errors and coating scratches during manual flipping. This ensures the core column returns to its spraying position after flipping. The variable frequency motor 23 drives the stirring paddle 24 to continuously stir within the mixing tank 21, effectively preventing the sedimentation of functional particles in the coating liquid, ensuring uniform coating composition, and avoiding coating composition differences or nozzle 253 blockage due to uneven coating concentration. The fixed seat 2... 52 is connected to the nozzle 253 by a rotating shaft, and driven by the rotary motor 254, the nozzle 253 can be adjusted at multiple angles to ensure that the nozzle 253 can spray the core column from the appropriate angle, ensuring the uniformity and integrity of the coating on the core column surface. The connection pipe 4, pump body 5 and delivery pipe 6 provide a stable supply of coating liquid during the spraying process, ensuring that the supply of coating liquid at the nozzle 253 is uniform. The high-pressure gas generated by the external air pump enters the nozzle 253 through the air inlet pipe 7 and can be fully mixed with the coating liquid delivered by the delivery pipe 6, so that the coating liquid forms fine and uniform atomized particles. The atomized coating liquid particles can adhere more evenly to the core column surface. The setting of the control cabinet 8 and the display screen 9 improves the convenience of device operation and the controllability of process parameters.

[0032] The working principle of this utility model is as follows: The operator puts the diamond synthetic core column to be sprayed into the column loading groove 35, starts the variable frequency motor 23, and drives the stirring paddle 24 to rotate in the inner cavity of the mixing tank 21 to uniformly stir the coating liquid in the tank, prevent the functional particles in the coating liquid from settling, and ensure that the composition of the coating liquid remains uniform. At the same time, the pump body 5 is started, and the coating liquid is sucked into the pump body 5 through the connecting pipe 4 and transported to the nozzle 253 through the delivery pipe 6. The external air pump is started, and high-pressure gas enters the nozzle 253 through the air inlet pipe 7 and is fully mixed with the coating liquid transported to the nozzle 253 through the delivery pipe 6, so that the coating liquid forms fine and uniform atomized particles to spray the surface of the core column.

[0033] When the servo motor 32 is powered on, it drives the turntable 33 to rotate. The positioning seat 34 rotates synchronously with the turntable 33, which in turn drives the core column to rotate at a constant speed. The rotary motor 254 drives the nozzle 253 to rotate around the rotating shaft on the fixed seat 252 and adjusts it to a spraying angle that matches the core column. The atomized coating particles are sprayed onto the surface of the core column.

[0034] After the circumferential surface and the first end face of the core column are coated, the second electric push rod 363 is energized and extends, driving the drive motor 364, the connecting seat 365, and the pneumatic clamps 366 on both sides to approach the core column until the pneumatic clamps 366 clamp the core column. The first electric push rod 362 is energized and extends, driving the second electric push rod 363 to adjust to a certain height. The drive motor 364 is energized and runs, driving the connecting seat 365 and the pneumatic clamps 366 to rotate 180° synchronously, so that the uncoated second end face of the core column faces upward. The second electric push rod 363 retracts, driving the core column to return to the mounting slot 35. The pneumatic clamps 366 release the core column. Then, the servo motor 32 starts again, driving the core column to rotate at a constant speed. The rotary motor 254 adjusts the nozzle 253 to an angle that matches the second end face. The external air pump and the pump body 5 work synchronously, and the atomized coating liquid is used to supplement the coating on the second end face and circumferential surface of the core column to ensure that the coating on the second end face of the core column is uniform.
