Description

Technical Field

[0001] This utility model relates to the field of ceramic blank trimming technology, specifically a daily-use ceramic blank trimming device. Background Technology

[0002] Daily-use ceramics refer to ceramic products used in daily life to meet basic functional needs. They typically include tableware, teaware, kitchenware, and sanitary ceramics. When processing ceramic blanks with basin-like structures, their surfaces are not very smooth, and the edges often have rough edges. Therefore, the edges need to be polished to trim them. Currently, the processing of these blanks often involves manual hand-holding of the workpiece and contact with the polishing equipment for grinding and trimming. Manual polishing makes it difficult to guarantee the consistency and precision of the trimming for each workpiece, especially for complex basin-like structures. Due to differences in each worker's operating habits and skill level, manual polishing can lead to certain quality fluctuations, making it difficult to guarantee the stability of the final product quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a trimming device for daily-use ceramic blanks, comprising: a belt conveyor 23, a dual-shaft cylinder 3 18 for positioning the workpiece fixedly connected to the top of the conveyor 23, an infrared sensor fixedly connected to the top of the support frame 1, and when the infrared sensor detects the position of the blank, the material is placed in the middle of the dual-shaft cylinder 3 18 and corresponds to the position of the vacuum suction cup 22; a material picking assembly is placed above the conveyor 23, the material picking assembly includes a vacuum suction cup 22 and a drive unit for driving the vacuum suction cup 22 to rise, fall, and move laterally; a rotating table 2 is rotatably placed on one side of the conveyor 23, and the conveyor 23... Multiple hollow placement platforms 4 are equidistantly connected in the middle. A hollow transmission disk 5 is fixed to the bottom of the placement platform 4. A transmission disk 6 is raised and lowered below the transmission disk 5 for friction transmission connection with the transmission disk 5. Both the transmission disk 5 and the transmission disk 6 are bonded with rubber rings. The trimming assembly is placed on one side of the rotary table 2. The trimming assembly includes a dual-axis cylinder 12 and a grinding part with the end of the dual-axis cylinder 12 installed. It is used to grind the bottom and top edges of the blank. After grinding, the rotary table 2 drives the workpiece to rotate to the unloading position. The blank is picked up and transferred to the conveyor 23 by the vacuum suction cup 22.

[0024] It should be noted that a PLC controller is provided in this embodiment, and the servo motors are all equipped with encoders. The conveyor 23 conveys the basin-shaped billet forward. After the infrared sensor detects its position information, the controller controls the conveyor 23 to stop conveying, and the dual-axis cylinder 18 extends to push and position the billet. Then, the drive unit drives the vacuum suction cup 22 to lift and move laterally, transporting the billet from the top of the conveyor 23 to the top of the corresponding placement table 4. The rotary table 2 drives the placement table 4 to rotate to the position of the grinding part. The transmission disk 2 6 is attached to the transmission disk 1 5. The bottom of the transmission disk 2 6 is connected to a negative pressure setting to draw a negative pressure inside the placement table 4, thereby adsorbing and fixing the workpiece on the top of the placement table 4. Then, under the drive of the corresponding motor, the transmission disk 2 6 drives the transmission disk 1 5 to rotate through friction. The transmission disk 1 5 drives the placement table 4 to rotate. At the same time, the grinding part moves laterally under the drive of the dual-axis cylinder 12, so that the grinding part contacts the grinding part, thereby grinding the billet.

[0025] In one embodiment, two dual-axis cylinders 18 are symmetrically arranged, and the output ends of each dual-axis cylinder 18 are fixed with arc-shaped plates for extruding and positioning the workpiece.

[0026] It should be noted that in this embodiment, the arc-shaped plate is adapted to the outer wall of the basin-shaped billet. When the infrared sensor detects the billet, the billet is located between the two arc-shaped plates. The two dual-axis cylinders 18 drive the arc-shaped plates to move towards the center at the same time, thereby positioning the billet so that it can be easily cooperated with the vacuum suction cup 22.

[0027] In one embodiment, the drive unit includes two brackets 19 symmetrically arranged on both sides of the rotary table 2. A linear module 20 is fixedly connected to the top of the bracket 19. A cylinder 21 is fixedly connected to the moving slide of the linear module 20. A metal plate is fixedly connected to the output end of the cylinder 21. A vacuum suction cup 22 is fixedly connected to the bottom of the metal plate.

[0028] It should be noted that in this embodiment, a nozzle is installed at one end of the second bracket 19. The nozzle is connected to a high-pressure air source. When the placement platform 4 rotates to a position close to the second bracket 19, the nozzle blows air to clean the placement platform 4. Two metal rods are fixedly connected to the top of the metal plate. The metal rods are slidably connected to the movable slide. The top of the vacuum suction cup 22 is connected to the vacuum generator through a pipe. The linear module 20 drives the cylinder 21 to move laterally through the movable slide. Under the action of the limit switch, the cylinder 21 moves to the middle position of the two arc plates and stops. The cylinder 21 drives the vacuum suction cup 22 to move downward to adsorb the blank and lift it. Then, under the lateral movement of the linear module 20, the blank is transported to the top of the placement platform 4. Then the cylinder 21 moves downward to place the blank on the top of the placement platform 4.

[0029] In one embodiment, a support frame 1 is provided below the rotary table 2, the rotary table 2 is rotatably mounted on the top of the support frame 1, and a servo motor 3 for driving the rotary table 2 to rotate is fixed inside the support frame 1.

[0030] It should be noted that in this embodiment, under the action of the encoder, the controller controls the conveyor 23 to rotate at a fixed angle. The servo motor 3 drives the rotary table 2 to rotate at a fixed angle, so that while the two placement tables 4 are loading and unloading materials, the other placement table 4 cooperates with the grinding part.

[0031] In one embodiment, a movable slider 9 is vertically slidably connected to one side of the support frame 1, and a dual-axis cylinder 10 is fixedly connected to one side of the support frame 1 to drive the movable slider 9 to slide. A hollow rotating shaft 8 is rotatably connected to the middle of the movable slider 9, and a servo motor 7 is installed in the middle of the movable slider 9 to drive the rotating shaft 8 to rotate. The servo motor 7 is connected to the rotating shaft 8 through a synchronous belt and a synchronous pulley. A transmission disk 6 is fixedly connected to the top of the rotating shaft 8, and the bottom of the rotating shaft 8 is connected to a vacuum pump through a rotary joint.

[0032] It should be noted that, in this embodiment, with the cooperation of the encoder of servo motor 3, when servo motor 3 drives the rotary table 2 to rotate to a specified angle and then stops, the controller controls the dual-axis cylinder 10 to drive the sliding slider 9 to slide along the slide rail fixed to the support frame 1. The sliding slider 9 drives the rotating shaft 8 to move upward, and the sliding slider 9 drives the transmission disk 6 to move upward and fit against the transmission disk 5. At this time, the vacuum pump evacuates the air inside the rotating shaft 8 through the rotary joint, thereby creating a negative pressure in the middle of the placement table 4, so that the billet is adsorbed and fixed on the top of the placement table 4. The servo motor 7 drives the rotating shaft 8 to rotate through the synchronous belt assembly, thereby driving the billet to rotate through the rotating shaft 8 and the placement table 4.

[0033] In one embodiment, the grinding section includes a bracket 11 fixed to the side of the support frame 1 facing away from the conveyor 23. A U-shaped plate is fixed to the top of the bracket 11. A dual-axis cylinder 12 is fixed to the top of the U-shaped plate. A slide rail that is slidably connected to a movable slider 13 is fixed to the top of the U-shaped plate. The output end of the dual-axis cylinder 12 is fixedly connected to the movable slider 13. A servo motor 14 is fixedly connected to the top of the movable slider 13. A grinding disc 15 is fixedly connected to the output end of the servo motor 14. A servo motor 16 is fixedly connected to the bottom of the movable slider 13 through a metal frame. The metal frame is slidably positioned in the middle of the U-shaped plate. A grinding disc 17 is fixedly connected to the output end of the servo motor 16.

[0034] It should be noted that in this embodiment, after the placement platform 4 drives the workpiece to rotate, the dual-axis cylinder 2 12 drives the moving slider 2 13 to move laterally. The moving slider 2 13 drives the servo motor 3 14 and the servo motor 4 16 to move towards the blank. Under the action of the limit switch, the servo motor 3 14 drives the grinding disc 15 to rotate and contact the top edge of the blank, and the servo motor 4 16 drives the grinding disc 2 17 to rotate and contact the bottom edge of the blank, thereby grinding the top and bottom edges.
