DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] A ceramic cup shadow engraving processing device, such as Figures 1-13As shown, it includes a frame 1, a laser engraver 2 fixed on the top of the frame 1, a conveying mechanism 3 installed on the frame 1 is provided below the laser engraver 2, and a plurality of clamping mechanisms 4 provided on the conveying mechanism 3 for fixing the ceramic cup. When making the ceramic cup, firstly, suitable materials are selected, the materials are ground and various materials are mixed to be crushed and then mixed to purify and form a clay material with good plasticity. After the materials are solidified, they are thrown into shape and the wet blanks are dried to a dry state to control the humidity of the materials. Then, the blanks are trimmed to retain the plasticity of the materials and avoid cracking. Then, the materials are placed on the conveying mechanism 3 of the shadow engraving machine and the ceramic cups are fixed by the clamping mechanism 4, and the conveyor Mechanism 3 drives the ceramic cup to the lower end of the laser engraver 2 for laser engraving. The thickness of the ceramic cup needs to be less than two millimeters through shadow engraving. At the same time, engraving will reduce the impact resistance of the ceramic and increase the brittleness of the ceramic. However, the surface finish of Ra<0.4μm can be achieved with high precision, which is close to the mirror surface. Compared with the surface finish of the traditional process, which is generally greater than 1.6μm, the product formed reduces the polishing requirements, and the product formed in this way is more exquisite and special. Therefore, after using the shadow engraving machine, the conveying mechanism 3 is fixed with an adjustment device 5 for driving the clamping mechanism 4 to lift and rotate. The conveying mechanism 3 includes two parallel baffles 31, which are respectively provided at both ends of the two baffles 31 and installed between the two baffles 31. The transmission shaft 32 of the two transmission A transmission chain 33 is provided between the shafts 32, and a sprocket 34 for driving the transmission chain 33 to rotate is provided on the transmission shaft 32, and a driving motor 35 for driving the transmission shaft 32 is also fixed to the outside of one of the baffles 31; the clamping mechanism 4 includes a U-shaped frame 41, and the two ends of the U-shaped frame 41 are rotatably connected to the rotating column 42, and the rotating column 42 is provided with a paddle 43 at one end close to the baffle 31, and a clamping member 44 for fixing the ceramic cup at the other end. A number of fixed seats 36 are evenly and equidistantly provided on the transmission chain 33, and a first limiting groove 361 for inserting the paddle 43 is provided in the middle of the fixed seat 36. The adjusting device 5 includes a mounting seat 51 fixed on the baffle 31 and corresponding to the laser head of the laser engraver 2, and the mounting seat 51 faces the clamping mechanism 4 is provided with an opening on one side, and a lifting frame 52 is provided at the opening of the mounting seat 51. First guide rails 511 are provided on both sides of the opening of the mounting seat 51 for the lifting frame 52 to slide up and down. The lifting frame 52 is connected to a transmission rod 53 when it rotates toward the side of the clamping mechanism 4. A second limiting groove 531 is provided at the front end of the transmission rod 53 for the paddle 43 to be inserted. A supporting plate 521 coaxial with the transmission rod 53 is fixed to the side of the lifting frame 52 facing the clamping mechanism 4. The mounting seat 51 is also provided with a driving assembly for driving the lifting frame 52 to slide up and down and the transmission rod 53 to rotate. A locking cap 512 extending toward the clamping mechanism 4 is further provided on the top of the mounting seat 51. A locking groove 513 is provided at the bottom of the locking cap 512 and engaged with the top of the U-shaped frame 41.During use, two manipulators are respectively provided at the front and rear ends of the conveying mechanism 3. The manipulator at the front end is responsible for placing the ceramic cups to be processed into the clamping mechanism 4 at the front end of the conveying mechanism 3 in sequence, while the manipulator at the rear end is responsible for taking out the processed ceramic cups. The clamping mechanism 4 clamps and fixes the ceramic cups through the clamping member 44. Subsequently, the driving motor 35 drives the transmission chain 33 to rotate clockwise in sequence through the transmission shaft 32 and the sprocket 34, thereby driving the fixed seat 36 to move synchronously. At the same time, the paddle 43 of the clamping mechanism 4 passes through the first limit groove. 361 is placed in the fixing seat 36, and the clamping mechanism 4 moves to the bottom of the laser engraver 2 along with the fixing seat 36. The paddle 43 is in a vertical state and is located above the second limiting groove 531 of the transmission rod 53. At the same time, both ends of the U-shaped frame 41 are located directly below the locking cap 512, and the two side plates are aligned with the locking groove 513. At this time, the driving assembly drives the lifting frame 52 to move up along the first guide rail 511, so that the paddle 43 is inserted into the second limiting groove 531 at the front end of the transmission rod 53, and the bottom of the paddle 43 is close to the top of the supporting plate 521. The components continue to drive the lifting frame 52 to move upward, and the tops on both sides of the U-shaped frame 41 are embedded in the locking grooves 513 from the bottom of the locking caps 512 to ensure that the U-shaped frame 41 remains in a fixed state. At the same time, the paddle 43 of the clamping mechanism 4 is separated from the fixing seat 36. At this time, the driving component drives the transmission rod 53 to rotate, thereby driving the paddle 43 to rotate synchronously through the transmission rod 53, prompting the rotating columns 42 at both ends of the U-shaped frame 41 to rotate synchronously. At the same time, the rotating column 42 drives the clamping component 44 and the ceramic cup to rotate simultaneously with the rotating column 42, thereby facilitating the laser engraver 2 to rotate. The outer wall of the ceramic cup is engraved. After the engraving is completed, the driving assembly causes the transmission rod 53 to stop rotating and reset. At this time, the paddle 43 is in a vertical state and the transmission chain 33 drives the fixing seat 36 to move downward. The paddle 43 is aligned with the first limiting groove 361. Then the driving assembly drives the lifting frame 52 to move downward, causing the paddle 43 to be inserted into the first limiting groove 361. The clamping mechanism 4 and the engraved ceramic cup are driven by the transmission chain 33 and the fixing seat 36 to move to the right end of the baffle 31. Then, the engraved ceramic cup is removed by the rear-end manipulator.

[0042] Therefore, the clamping mechanism 4 is installed in the fixed seat 36 of the conveying mechanism 3 by a movable connection. When the clamping mechanism 4 moves to above the adjusting device 5, the clamping mechanism 4 is lifted upward by the driving component, so that the clamping mechanism 4 is disengaged from the fixed seat 36, and drives the ceramic cup on the clamping mechanism 4 to rotate and engrave. At the same time, the transmission chain 33 of the conveying mechanism 3 maintains rotating transportation. Therefore, when the conveying mechanism 3 takes and places the ceramic cup, the ceramic cup can be engraved normally, realizing a continuous processing flow without stagnation and waiting time, thereby improving the processing efficiency of ceramic cup engraving.

[0043] The supporting plate 521 serves to fix the paddle 43 and prevent the paddle 43 from moving downward.

[0044] At the same time, the diameter of the supporting plate 521 is equal to the length of the paddle 43, and since the supporting plate 521 is a semicircular arc structure and is coaxially arranged with the transmission rod 53, when the lifting frame 52 moves up so that the paddle 43 is inserted into the second limiting groove 531 and the bottom of the paddle 43 is tightly pressed against the upper surface of the supporting plate 521, the midpoint of the paddle 43 is aligned with the axis of the transmission rod 53, and the midpoint of the paddle 43 is also aligned with the axis of the rotating column 42 and the clamping member 44. During the process of the transmission rod 53 driving the paddle 43 to rotate, the center of the paddle 43, the axis of the transmission rod 53, the axis of the rotating column 42, and the axis of the clamping member 44 are always aligned, thereby avoiding the up and down movement of the paddle 43 causing the distance between the ceramic cup and the laser engraver 2 to change, thereby causing inconsistent engraving depth, thereby improving the accuracy and stability of the ceramic cup engraving processing.

[0045] Specifically, the driving assembly includes a first guide slot 514 provided on the back of the opening of the mounting seat 51, a driving plate 54 is further provided in the opening of the mounting seat 51, the driving plate 54 is provided at the rear of the lifting frame 52, and second guide rails 515 for the driving plate 54 to slide up and down are provided on both sides of the opening of the mounting seat 51, the driving plate 54 is provided with a second guide slot 541 which runs through the front and back and is inclined, the inner side of the baffle 31 is provided with a cylinder 55 which drives the driving plate 54 to slide up and down along the second guide rail 515, and the lifting frame 52 is provided with a rotation adjustment plate 56 and a second guide rail 515 for the rotation adjustment plate 56. The third guide rail 522 for the vertical movement of the section plate 56 is provided with a transmission gear 532 at one end of the transmission rod 53 facing the rotation adjustment plate 56. The rotation adjustment plate 56 is provided with a gear rod 561 that meshes with the transmission gear 532 for transmission. The back of the rotation adjustment plate 56 has an inclined third guide slot 562. The lifting frame 52 has a horizontally arranged fourth guide slot 523 extending through one side of the lifting frame 52 near the rotation adjustment plate 56. The lifting frame 52 also includes a guide post 57 that slidably cooperates with the first guide slot 514, the second guide slot 541, the third guide slot 562, and the fourth guide slot 523.

[0046] The first guide slot 514 is composed of a vertical section at the right end and a horizontal section at the left end. The second guide slot 541 of the drive plate 54 is inclined from left to right and from bottom to top. The fourth guide slot 523 extends horizontally. The third guide slot 562 is also inclined from left to right and from bottom to top.

[0047] Furthermore, the cylinder 55 is fixedly connected to the bottom of the driving plate 54 via a telescopic rod, thereby facilitating the control of the driving plate 54 to slide up and down along the second guide rail 515;

[0048] In the initial state, the guide slide 57 is at the bottom of the vertical section of the first guide slot 514, and cooperates with the top of the second guide slot 541, passes through the rightmost end of the fourth guide slot 523, and cooperates with the top of the third guide slot 562. When the clamping mechanism 4 with the ceramic cup moves to correspond to the adjusting device 5, the cylinder 55 pushes the driving plate 54 to move up along the second guide rail 515. At this time, the guide slide 57 moves up along the vertical section of the first guide slot 514, and at the same time drives the lifting frame 52 and the rotating adjustment plate 56 inside it to move up along the first guide rail 511 synchronously. At this time, the paddle 43 is inserted into the second limiting groove 531, and at the same time, the paddle 43 and the clamping mechanism 4 are pushed up by the supporting plate 521. After moving to the top of the vertical section along the first guide slot 514, as the cylinder 55 continues to push the driving plate 54 upward, the driving plate 54 drives the guide slide 57 to move leftward along the second guide slot 541. At the same time, one end of the guide slide 57 slides leftward along the horizontal section of the first guide slot 514, and the other end of the guide slide 57 slides leftward along the fourth guide slot 523. Since the third guide slot 562 is in an inclined state, at this time, the lifting frame 52 remains stationary, and the guide slide 57 drives the rotary adjustment plate 56 to move upward along the third guide rail 522, prompting the gear rod 561 to drive the transmission gear 532 to rotate, so that the transmission rod 53 rotates and synchronously drives the paddle 43 to rotate, thereby realizing the rotation engraving of the ceramic cup in the clamping mechanism.

[0049] When the cylinder 55 drives the driving plate 54 to be fully pushed out, the guide slide 57 moves to the bottom of the second guide slot 541 and abuts against the leftmost end of the first guide slot 514. The other end slides to the leftmost end of the fourth guide slot 523, pushing the rotary adjustment plate 56 to move completely upward, and the guide slide 57 abuts against the bottom of the third guide slot 562. Then the cylinder 55 begins to retract. At this time, the guide slide 57 moves upward in the second guide slot 541 and moves to the right along the horizontal section of the first guide slot 514. At the same time, it moves to the right along the fourth guide slot 523, causing the guide slide 57 to move upward along the third guide slot 562. Therefore, the rotary adjustment plate 56 moves downward along the third guide rail 522. The gear rod 561 drives the transmission gear 532 to rotate in the opposite direction. The transmission rod 53 drives the paddle 43 to rotate in the opposite direction synchronously. The clamping member 44 drives the ceramic cup to reverse synchronously. During the reversal process, the laser engraver 2 repeatedly engraves the surface of the ceramic cup After the first guide slot 514 is fully engaged, the guide pin 57 is pulled back to the left of the workbench and the guide pin 57 is pulled back to the right of the workbench.

[0050] In order to realize the automatic clamping and loosening of the ceramic cup by the clamping mechanism, the U-shaped frame 41 has a screw 45 rotatably connected to both ends. The two ends of the screw 45 respectively pass through the two sides of the U-shaped frame 41 and have a coaxially arranged traction gear 451. The screw 45 is provided with two mutually opposite threads extending from the middle to both sides. The clamping member 44 includes a traction block 441 threadedly connected to the screw 45. The traction block 441 is provided with a rotatably connected clamping rod 442. The traction block 441 has a fixing hole 443 that rotatably cooperates with the clamping rod 442. The rotating column 42 is provided with a clamping rod 442. The rod 442 slides along the telescopic slot 421 in the length direction of the screw 45. The inner wall of the telescopic slot 421 is provided with a guide block 422. The side wall of the clamping rod 442 is provided with a slide rail 444 that cooperates with the guide block 422. The inner ends of the baffle 31 are respectively provided with a first drive ring 61 and a second drive ring 62 coaxially arranged with the transmission shaft 32. The first drive ring 61 is provided with a first transmission tooth 611 that meshes with the outer trajectory of the traction gear 451 rotating along the transmission chain 33. The second drive ring 62 is provided with a second transmission tooth 621 that meshes with the inner trajectory of the traction gear 451 rotating along the transmission chain 33.

[0051] It should be noted that the first drive ring 61 and the second drive ring 62 are respectively provided at the front end and the rear end of the conveying mechanism 3, the first transmission teeth 611 and the second transmission teeth 621 are respectively a quarter circle, and the first transmission teeth 611 are provided at the upper left corner of the first drive ring 61, and the second transmission teeth 621 are provided at the upper right corner of the second drive ring 62;

[0052] Therefore, as the clamping mechanism 4 rotates clockwise along with the transmission chain 33, when the clamping mechanism 4 moves to the left end of the baffle 31, the traction gears 451 at both ends of the screw 45 respectively mesh with the first transmission teeth 611 of the first drive ring 61 for transmission, so that the two traction blocks 441 move toward the middle along the screw 45, and at the same time, the traction block 441 drives the clamping rod 442 to extend outward along the telescopic slot 421, and at the same time, the slide rail 444 slides along the guide block 422, so that the ceramic cup is clamped and fixed by the two clamping rods 442, wherein the clamping rod 442 and the traction block 441 are rotatably connected, and the guide block 422 and the slide rail 444 cooperate with each other, so when the paddle 43 drives the rotating column 42 to rotate, the clamping member 44 rotates synchronously, thereby realizing rotary engraving of the ceramic cup;

[0053] When the clamping mechanism 4 moves to the right end of the transmission chain 33, the traction gears 451 at both ends of the screw 45 respectively engage with the first transmission teeth 611 of the second drive ring 62 for transmission, causing the screw 45 to rotate in the opposite direction, and the two traction blocks 441 move toward both ends along the screw 45. At the same time, the traction block 441 drives the clamping rod 442 to retract inward along the telescopic slot 421, and at the same time, the slide rail 444 slides along the guide block 422, thereby releasing the clamping of the ceramic cup through the two clamping rods 442, making it easier for the robot to remove the processed ceramic cup.

[0054] Furthermore, a retaining ring 445 is provided on the side wall of the clamping rod 442; a clamping plate 446 is provided at the front end of the clamping rod 442, and the traction block 441 is further limited by the clamping plate 446 and the retaining ring 445, so that the traction block 441 is located between the clamping plate 446 and the retaining ring 445, ensuring that the clamping rod 442 moves synchronously with the traction block 441, thereby realizing automatic clamping and release of the ceramic cup;

[0055] Among them, the side of the clamping disc 446 used for clamping the ceramic cup is provided with a rubber pad, which can effectively prevent the ceramic cup from being bumped or damaged during the clamping process.

[0056] At the same time, a coil spring 46 is provided in the telescopic groove 421, which pushes the clamping rod 442 to maintain the longitudinal preload force, preventing the ceramic cup from loosening during the clamping process and causing damage to the ceramic cup, thereby ensuring the safety and stability of the ceramic cup during the entire operation process.

[0057] In order to improve the safety and stability of the clamping mechanism 4 when it moves in the conveying mechanism 3, the baffle 31 is also provided with a limiting guide rail 7 that is slidably connected to the top of the two ends of the U-shaped frame 41 along the rotation trajectory of the transmission chain 33. The limiting guide rail 7 includes arc sections located at the left and right ends of the baffle 31 and a straight section connecting the bottom of the two arc sections. Therefore, when the U-shaped frame 41 moves to the limiting guide rail 7, the side plates at both ends slide along the limiting guide rail 7 to prevent the clamping mechanism from falling downward when it moves to the bottom of the transmission chain 33, thereby improving the stability of the clamping mechanism during operation and ensuring that the clamping device is always in a safe position.

[0058] In order to reduce the friction between the U-shaped frame 41 and the limiting guide rail 7, rollers 411 are further provided at the top of both ends of the U-shaped frame 41. During the movement, the rollers 411 fit into the inner wall of the limiting guide rail 7.

[0059] In order to improve the accuracy of the insertion of the paddle 43 into the first limiting groove 361, the upper and lower ends of the paddle 43 are both arc-shaped structures; smooth inward-inclined inclined surfaces are provided on both sides of the top of the first limiting groove 361. When in use, the paddle 43 is inserted into the first limiting groove 361 along the inclined surfaces.

[0060] The width of the U-shaped frame 41 is equal to the distance between the two corresponding fixed seats 36 on the front and rear transmission chains 33, thereby preventing the U-shaped frame 41 from shifting forward and backward when moving in the conveying mechanism 3, ensuring that each ceramic cup always maintains a fixed relative position during the engraving process, thereby avoiding position deviation and ensuring high precision and consistency during the engraving process.

[0061] A ceramic cup shadow engraving process adopts the above-mentioned ceramic cup shadow engraving device, and the specific steps are as follows:

[0062] S1. The clamping mechanism 4 is installed in the fixed seat 36. The ceramic cups to be processed are placed in the clamping area of ​​the clamping mechanism 4 at the front end of the conveying mechanism 3 in sequence by the front-end manipulator. The clamping mechanism 4 fixes the ceramic cups by the clamping member 44.

[0063] S2, the conveying mechanism 3 rotates clockwise on the frame 1, thereby driving the clamping mechanism 4 to move to the processing area below the laser engraver 2;

[0064] S3. The driving assembly is activated, thereby driving the lifting frame 52 to move upward, and driving the clamping mechanism 4 to move upward synchronously. During the upward movement, the clamping mechanism 4 is separated from the fixing seat 36, and the paddle 43 of the clamping mechanism 4 is coaxially connected to the transmission rod 53;

[0065] S4, after the lifting frame 52 moves to the top, the lifting frame 52 and the transmission rod 53 remain stationary, and then the driving assembly starts to drive the transmission rod 53 to rotate, and the transmission rod 53 drives the rotating column 42 and the clamping member 44 to rotate synchronously, so that the ceramic cup rotates synchronously;

[0066] S5, during the rotation of the clamping mechanism 4, the laser engraver 2 identifies the position and shape of the ceramic cup, and then engraves the outer wall of the ceramic cup to form a preset pattern and text;

[0067] S6. After the engraving is completed, the driving assembly stops the rotation of the transmission rod 53 and drives the lifting frame 52 to move downward. The clamping mechanism 4 moves downward synchronously and is clamped into the fixing seat 36.

[0068] S7, the transmission chain 33 continues to rotate and drives the clamping mechanism 4 to move to the right end of the baffle 31, and the engraved ceramic cup is removed by the robot at the rear end.
