Description

Technical Field

[0001] This invention relates to the technical field of polishing devices, and more specifically to an animation model polishing device. Background Technology

[0002] With the rapid development of the animation and cultural creative industry, the demand for the production and customization of various animation models, such as animation figurines, GK resin models, model kits, and film and television prop models, continues to increase. After the models are formed through processes such as injection molding, 3D printing, and resin casting, defects such as parting lines, sprue residue, layer lines, and unevenness are common on the surface. These defects need to be eliminated and the surface smoothness improved through grinding and polishing, which is a core process to ensure the effect of subsequent painting and assembly.

[0003] Meanwhile, the substrates of animation models are mostly made of resin, photosensitive resin, ABS plastic, etc., which generate a large amount of fine dust during the sanding process. This dust is easily dispersed into the air, and long-term inhalation can harm the respiratory health of operators. Existing sanding equipment is mostly equipped with independent external dust collection devices, which can remove floating dust, but it is difficult to remove stubborn abrasives attached to the model surface. After sanding, additional cleaning processes such as wiping and blowing are still required, which is a long process. Incomplete cleaning can also directly affect the adhesion of subsequent coatings and the quality of the finished product. Summary of the Invention

[0004] The purpose of this invention is to provide an animation model polishing device to overcome the above-mentioned defects in the prior art.

[0006] Furthermore, the limiting mechanism includes a turntable, a right-angle motor, and a cylinder. The turntable is rotatably connected to the worktable. The right-angle motor is installed at the bottom of the worktable and its output shaft is connected to the turntable. A fixed plate is provided on the top of the turntable.

[0007] Furthermore, the position adjustment mechanism includes a drive screw, a drive motor, a swing frame, a cylinder, and a cylinder. A movable frame is slidably connected to the worktable. Both ends of the drive screw are rotatably connected to the worktable. The drive motor is mounted on the movable frame, and its output shaft is connected to the drive screw. The movable frame is screwed to the drive screw via a screw nut. One end of the swing frame is rotatably connected to the top of the movable frame. The cylinder body of cylinder two is hinged to the side of the movable frame via a pin. The upper end of the piston rod of cylinder two is hinged to the swing frame via a pin. A swing arm is hinged to the swing frame via a pin. The cylinder body of cylinder three is hinged to the swing frame via a pin. The end of the piston rod of cylinder three is hinged to the swing arm via a pin.

[0008] Furthermore, the grinding mechanism includes a grinding disc and a second drive motor. The grinding disc is rotatably connected to the swing arm via a rotating shaft. The second drive motor has a support plate and its output shaft equipped with a pulley. The pulley is connected to the second pulley on the rotating shaft via a drive belt.

[0009] Furthermore, the cleaning mechanism includes an air collecting cylinder, a dust suction plate, a limiting rope, a spring, and a scraper. The air collecting cylinder is sleeved on the rotating shaft and its inner side is connected to the swing arm. The air collecting cylinder is connected to the dust suction pump through a pipe. The dust suction plate has an arc-shaped structure and is made of elastic material. The side of the dust suction plate facing the grinding disc has several suction holes. The end of the dust suction plate is provided with a limiting rope connected to the swing arm. The swing arm is provided with a support plate. The upper end of the support plate is provided with a guide cylinder sleeved on the limiting rope. The spring is sleeved on the limiting rope and located between the dust suction plate and the guide cylinder. The scraper is located at the lower end of the dust suction plate and is made of rubber material.

[0010] Furthermore, the fixing frame is provided in two parts and symmetrically arranged on the turntable.

[0011] Furthermore, the fixed disk and the turntable are connected by several fixed posts.

[0012] Furthermore, a pad for supporting the model components is provided coaxially in the middle of the fixed disk.

[0013] Furthermore, the bottom sides of the movable frame are slidably connected to the slide rails on both sides of the worktable via several sliders.

[0014] The beneficial effects achieved by this invention are as follows: 1.

The grinding and cleaning operations are carried out simultaneously: on the one hand, the dust generated by grinding is sucked up in real time through the suction holes of the dust suction plate to avoid dust diffusion and ensure the cleanliness of the working environment and the health of personnel; on the other hand, the rubber scraper at the lower end of the dust suction plate simultaneously scrapes off the grinding debris and impurities attached to the surface of the workpiece. Grinding and surface cleaning are completed in one step, eliminating the need for secondary cleaning processes, while ensuring the cleanliness of the ground surface, which is beneficial for subsequent coating processing.

[0015] 2. The dust collection plate of this application adopts an elastic arc-shaped structure, combined with a structure consisting of a limiting rope, a spring, and a guide cylinder. It can adaptively conform to the undulations of the model surface, always maintaining the optimal distance between dust collection and scraping, and ensuring stable cleaning effect at different curved surface positions. When the grinding position moves upward and the workpiece is released from the constraint on the upper part of the dust collection plate, the dust collection plate can deform under the action of spring force and its own elasticity, automatically shaking off the dust and impurities adsorbed on the suction hole and scraper, avoiding the dust hole blockage, achieving a self-cleaning effect, and extending the continuous operation time of the equipment.

[0016] 3. The position adjustment mechanism of this application realizes the horizontal forward and backward displacement of the grinding mechanism through the screw drive. Combined with the swing structure of the two-cylinder driven swing frame pitch and the three-cylinder driven swing arm swing, it can realize the multi-dimensional position and angle adjustment of the grinding disc. It can flexibly adapt to the complex curved surface of the animation model, with a wide grinding coverage and high adjustment accuracy, meeting the grinding needs of different model shapes.

[0024] like Figure 1-5 As shown, the present invention provides an animation model polishing device, including a worktable 1, a limiting mechanism 2, a position adjusting mechanism 3, a polishing mechanism 4, and a cleaning mechanism 5; It should be noted that the limiting mechanism 2 is set on the workbench 1 and is used to fix the model parts. The limiting mechanism 2 includes a turntable 21, a right-angle motor 22 and a cylinder 26. The turntable 21 is rotatably connected to the workbench 1. The right-angle motor 22 is installed at the bottom of the workbench 1 and its output shaft is connected to the turntable 21. The top of the turntable 21 is provided with a fixed plate 23. The fixed plate 23 and the turntable 21 are connected by several fixed columns 211. The middle of the fixed plate 23 is coaxially provided with a pad for supporting the model parts.

In addition, the turntable 21 is provided with a fixing frame 25. There are two fixing frames 25 symmetrically arranged on the turntable 21. Each fixing frame 25 is provided with a cylinder 26 on its side. The upper end of the piston rod of each cylinder 26 is rotatably connected to a pressure plate 27. The model's angular rotation is achieved using a turntable 21 and a right-angle motor 22. Combined with multiple limit blocks 24 with inclined surfaces and a cylinder-driven pressure plate 27, it can quickly clamp model parts of different shapes, making it suitable for rapid mold changes in mass production.

[0025] In addition, the position adjustment mechanism 3 is mounted on the workbench 1. The position adjustment mechanism 3 includes a drive screw 32, a drive motor 33, a swing frame 34, a cylinder 35, and a cylinder 37. A movable frame 31 is slidably connected to the workbench 1. The two sides of the bottom of the movable frame 31 are slidably connected to the slide rails on both sides of the workbench 1 through several sliders. The two ends of the drive screw 32 are rotatably connected to the workbench 1. The drive motor 33 is mounted on the movable frame 31 and its output shaft is connected to the drive screw 32. However, the movable frame 31 is screwed to the drive screw 32 via a screw nut, one end of the swing frame 34 is rotatably connected to the top of the movable frame 31, the cylinder body of the second cylinder 35 is hinged to the side of the movable frame 31 via a pin, the upper end of the piston rod of the second cylinder 35 is hinged to the swing frame 34 via a pin, the swing frame 34 is hinged to the swing arm 36 via a pin, the cylinder body of the third cylinder 37 is hinged to the swing frame 34 via a pin, and the end of the piston rod of the third cylinder 37 is hinged to the swing arm 36 via a pin, thereby realizing the coarse and fine adjustment of the pitch angle of the grinding mechanism 4; In addition, the grinding mechanism 4 includes a grinding disc 41 and a second drive motor 43. The grinding disc 41 is rotatably connected to the swing arm 36 via a rotating shaft 42. The second drive motor 43 has a pulley 431 on its support plate 44 and its output shaft. The pulley 431 is connected to the second pulley 45 on the rotating shaft 42 via a drive belt 46.

[0026] It is worth noting that the cleaning mechanism 5 is located on the adjustment mechanism. The cleaning mechanism 5 includes an air collecting cylinder 51, a dust suction plate 52, a limiting rope 53, a spring 56, and a scraper 57. The air collecting cylinder 51 is sleeved on the rotating shaft 42 and its inner side is connected to the swing arm 36. The air collecting cylinder 51 is connected to the dust suction pump through the pipe 511. The dust suction plate 52 has an arc-shaped structure and is made of elastic material. The dust suction plate 52 has several suction holes 521 on the side facing the grinding disc 41. The end of the dust suction plate 52 is provided with a limiting rope 53 connected to the swing arm 36. The swing arm 36 is provided with a support plate 54. The upper end of the support plate 54 is provided with a guide cylinder 55 sleeved on the limiting rope 53. The spring 56 is sleeved on the limiting rope 53 and is located between the dust suction plate 52 and the guide cylinder 55. The scraper 57 is located at the lower end of the dust suction plate 52 and is made of rubber. The arc-shaped elastic dust suction plate 52 forms a floating structure through the limiting rope 53 and the spring 56, which can fit the grinding area. The suction hole 521 efficiently collects smoke and dust, and the rubber scraper 57 at the lower end scrapes away the residual impurities during the rotation after grinding.

[0027] Detailed implementation methods and principles: In the initial state, the piston rod of cylinder 26 on the fixed frame 25 is in the extended state, the pressure plate 27 is raised, leaving space for clamping operation. The operator places the animation model part to be polished on the pad in the center of the fixed plate 23. The limiting blocks 24 evenly distributed around the circumference of the fixed plate 23 center and initially limit the bottom of the model part to prevent the workpiece from shifting horizontally. The cylinders 26 on the side of the fixed frame 25 move synchronously. The piston rod of the cylinder 26 retracts, causing the pressure plate 27 to swing downward and press against the edge of the model part on the non-machined surface, thus completing the reliable clamping of the workpiece. When the drive motor 33 starts, it drives the drive screw 32 to rotate. Through the screw nut's helical transmission, it drives the moving frame 31 to slide back and forth along the slide rails on both sides of the worktable 1, adjusting the horizontal and back-to-back position of the grinding disc 41 so that the grinding mechanism 4 is close to the workpiece. The piston rod of cylinder 35 extends and retracts, causing the swing frame 34 to swing around the hinge axis between it and the top of the moving frame 31, adjusting the overall pitch angle of the swing frame 34, and coarsely adjusting the vertical height and tilt posture of the grinding disc 41. The piston rod of cylinder 37 extends and retracts, causing the swing arm 36 to swing around the hinge axis between it and the swing frame 34, further finely adjusting the working angle and feed depth of the grinding disc 41, so that the grinding disc 41 stably fits the surface of the model part to be ground. Under the action of its own elasticity, the dust suction plate 52 adaptively fits the surface of the model part. The spring 56 on the limiting rope 53 squeezes the dust suction plate 52, which can stably fit the dust suction plate 52 and the scraper 57, ensuring stable dust suction effect throughout the area. Next, drive motor 43 starts, and drives the rotating shaft 42 and polishing disc 41 to rotate at high speed through pulley 431 on the output shaft, drive belt 46, and pulley 45 on the rotating shaft 42, so as to polish the surface of the model parts. The dust pump connected to the air collection cylinder 51 starts synchronously. The plastic dust and abrasive shavings generated during grinding are sucked into the air suction holes 521 on the surface of the dust collection plate 52 by the airflow. They then pass through the air collection cylinder 51 and the connecting pipe 511 in sequence and are collected by the dust pump to avoid the spread of grinding dust and pollution of the working environment. Under the action of the piston rod of cylinder 2 35, the swing arm 36 swings and under the action of the output shaft of drive motor 1 33, the moving frame 31 moves, so that the polishing disc 41 can polish the model parts from bottom to top. Once one area is finished being polished, the right-angle motor 22 starts, driving the turntable 21 to rotate at a constant speed. The fixed plate 23 and the clamped model parts rotate synchronously with the turntable 21, allowing the polishing plate 41 to polish the next area of ​​the workpiece in sequence. The rubber scraper 57 at the lower end of the dust suction plate 52 scrapes away the dust, shavings and other impurities remaining on the model surface, achieving surface cleaning after polishing. When the grinding disc 41 grinds and polishes the model parts from bottom to top, since the model parts no longer restrain the upper end of the dust suction plate 52, the dust suction plate 52 deforms at the upper end of the grinding disc 41 under the action of the spring 56 and its own elasticity. During the deformation process, the dust suction holes and the impurities remaining on the scraper 57 are shaken off accordingly. After grinding is completed, drive motor 2 43, dust pump and right angle motor 22 stop running in sequence, grinding disc 41 stops rotating and cleaning mechanism 5 stops working. Cylinder 2 35 and cylinder 3 37 drive swing frame 34 and swing arm 36 to lift upward, drive motor 1 33 rotates in the opposite direction, drive moving frame 31 back to the initial position, and make room for unloading operation.

[0028] The piston rod of cylinder 26 extends, causing the pressure plate 27 to lift upward and release the workpiece. The operator can then remove the polished animation model part, completing a single work cycle.

[0029] In summary, the cleaning mechanism 5 and the grinding mechanism 4 of this application are integrated on the swing arm 36 and move synchronously with the grinding disc 41. The grinding and cleaning operations are carried out simultaneously: on the one hand, the dust generated by grinding is sucked up in real time through the suction hole 521 of the dust suction plate 52 to avoid dust diffusion and ensure a clean working environment and personnel health; on the other hand, the rubber scraper 57 at the lower end of the dust suction plate 52 simultaneously scrapes off the grinding debris and impurities attached to the surface of the workpiece. Grinding and surface cleaning are completed in one step, eliminating the need for a secondary cleaning process, while ensuring the cleanliness of the ground surface, which is beneficial for subsequent coating processing. The dust suction plate 52 adopts an elastic arc-shaped structure, which, together with the limiting rope 53, spring 56 and guide cylinder 55, can adaptively conform to the undulations of the model surface, always maintaining the optimal distance between dust suction and scraping, and ensuring stable cleaning effect at different curved surface positions. When the grinding position moves upward and the workpiece is released from the constraint on the upper end of the dust suction plate 52, the dust suction plate 52 can deform under the elastic force of spring 56 and its own elasticity, automatically shaking off the dust and impurities adsorbed on the suction hole 521 and scraper 57, avoiding the dust suction hole blockage, achieving a self-cleaning effect, and extending the continuous operation time of the equipment.
