The curved surface positioning module is used for positioning the ceramic product. The curved surface positioning module works in conjunction with the deformable cutting module to trim the curved ceramic product. The deformable cutting module consists of a blade array composed of several independent small blade units. Each small blade unit is surrounded by a housing. Each small blade unit includes a cutting edge and a magnetic drive part. The magnetic drive part pushes the cutting edge to move axially by magnetic force. A magnetic drive module is located inside the housing and behind the blade array.

[0016] Preferably, the guiding mechanism includes a linear drive guide rail parallel to the knife unit, the linear drive guide rail is fixedly mounted on the upper part of the lifting plate, a guide seat is mounted on the linear drive guide rail, the linear drive guide rail drives the guide seat to reciprocate, and a positioning rotary fixture is fixedly mounted on the guide seat.

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

[0023] Example 1: Please see Figures 1-7 The present invention provides a technical solution: A trimming device for ceramic processing includes a deformable cutting module and a curved surface positioning mold 31. The curved surface positioning mold 31 is used for positioning ceramic products. The curved surface positioning mold 31 cooperates with the deformable cutting module to trim the curved ceramic products. The deformable cutting module consists of a blade array composed of several independent small blade units 1. A box 2 is provided outside the small blade unit 1. Each small blade unit 1 includes a blade part 3 and a magnetic drive part 4. The magnetic drive part 4 pushes the blade part 3 to move axially by magnetic force. A magnetic drive module 5 is provided inside the box 2 and behind the blade array. The magnetic drive module 5 is an electromagnetic coil array. The electromagnetic coil array drives the magnetic drive part 4 of each small blade unit 1 to move independently by electromagnetic force. A locking mechanism for locking the blade array is provided inside the front end of the box 2. The blade array is locked after it is adapted to the curved ceramic surface.

[0024] In the above scheme, the standard model ceramic product is first placed on the positioning rotary fixture of the curved surface positioning mold 31. The height is adjusted by the lifting column 23 of the lifting platform to initially align the ceramic curved surface with the blade array of the deformable cutting module. Next, the electromagnetic coil array of the magnetic drive module 5 is energized, generating an electromagnetic field that acts on the magnetic drive part 4 of each small blade unit 1, pushing it to move axially, so that the blade array as a whole flexibly deforms and completely conforms to the contour of the ceramic curved surface. After the deformation is completed, the electric push rod 14 of the locking mechanism drives the strip tooth plate to press into the pressure groove of the small blade unit 1, locking the position of the blade array. Then, the standard model is removed, and the ceramic product to be processed is placed in. The multi-axis robotic arm 20 drives the locked blade array to move along the preset trajectory. At the same time, the friction roller 29 of the positioning rotary fixture drives the ceramic product to rotate under the drive of the stepper motor, so that the blade part 3 continuously contacts the ceramic edge to complete the cutting. During the process, the pressure sensor 22 monitors the cutting force in real time to ensure the cutting accuracy. The entire system achieves high-precision adaptive cutting of curved ceramic products by first contouring and locking and then batch processing.

[0025] The curved positioning module 31 includes a lifting platform and a guide mechanism for carrying ceramic products. The lifting platform and the guide mechanism work together to fit and position the surface of the ceramic product with the blade array.

[0026] In the above scheme, the lifting platform drives the lifting column 23 to move up and down by hydraulic or electric means, which drives the lifting plate 24 and the guide mechanism installed on it to rise and fall as a whole, so that the surface of the ceramic product placed on the positioning rotating fixture and the blade array maintain a suitable relative height; the linear drive rail 25 of the guide mechanism can drive the guide seat 26 and the fixture to move in a direction parallel to the blade array, so as to achieve precise alignment between the ceramic product and the blade array and ensure that the two reach the best fit before cutting.

[0027] The locking mechanism includes a pressure plate 12. An adjustment groove 13 is provided on one side of the box body 2. The pressure plate 12 is slidably connected to the inside of the adjustment groove 13. An electric push rod 14 is fixedly installed on the side of the adjustment groove 13 away from the knife unit 1. The electric push rod 14 pushes the pressure plate 12 to slide perpendicular to the axial extension direction of the knife unit 1.

[0028] After the blade array completes the deformation adaptation, the electric push rod 14 starts to push the pressure plate 12 to slide laterally along the adjustment groove 13. The pressure plate 12 adopts a strip toothed plate design, and its toothed structure is precisely matched with the pressure groove on the side of each small blade unit 1. When the pressure plate 12 is pushed to the designated position, the toothed plate and the pressure groove are fully engaged, and the position of each small blade unit 1 is firmly fixed by mechanical interlocking to prevent displacement during the cutting process.

[0029] The pressure plate 12 is a strip toothed plate. The knife unit 1 is provided with a pressure groove that matches the strip toothed plate on the side near the pressure plate 12. When the pressure plate 12 and the knife unit 1 are clamped together, the strip toothed plate and the pressure groove are engaged.

[0030] The toothed bar of the pressure plate 12 adopts a trapezoidal or triangular cross-section design, which forms an interference fit with the corresponding shaped pressure groove on the side of the knife unit 1. When the electric push rod 14 applies pressure, the inclined surface of the toothed plate and the inclined surface of the pressure groove produce a wedge effect. As the pressure increases, the toothed plate is fully embedded in the pressure groove, forming a multi-point distributed locking to ensure the stability of the entire blade array.

[0031] The box body 2 has equidistantly distributed rib grooves 17 on the side away from the adjustment groove 13. Each knife unit 1 has a rib 18 on the side away from the pressure plate 12. The magnetic drive module 5 pushes the rib 18 of the knife unit 1 to slide along the inside of the rib groove 17.

[0032] The equidistant rib grooves 17 on the side of the box 2 provide a precise sliding track for the ribs 18 on the back of the knife unit 1. When the magnetic drive module 5 is working, the electromagnetic force pushes the ribs 18 of each knife unit 1 to move in a straight line along the rib grooves 17. The rib grooves 17 not only restrict the direction of movement, but also provide a reaction force through the side wall, so that the knife unit 1 can only move in the set direction, ensuring deformation accuracy.

[0033] The deformable cutting module is provided with a multi-axis adjustment unit on its outer side. The multi-axis adjustment unit includes a multi-axis robotic arm 20 and a mounting platform 21. The mounting platform 21 is fixedly connected to the ground. The fixed end of the multi-axis robotic arm 20 is fixedly connected to the mounting platform 21. The movable end of the multi-axis robotic arm 20 is fixedly connected to the end of the box 2 away from the blade 3. A pressure sensor 22 is installed between the movable end of the multi-axis robotic arm 20 and the box 2.

[0034] The mounting platform 21 provides a stable foundation for the multi-axis robotic arm 20. The robotic arm is driven by servo motors of each joint, which drive the housing 2 and the blade array to achieve precise movement in three-dimensional space. The pressure sensor 22 detects the cutting pressure in real time and feeds it back to the control system to dynamically adjust the force and movement trajectory of the robotic arm to ensure uniform and stable cutting force and avoid ceramic breakage due to uneven pressure.

[0035] Example 2: Please see Figures 2-7 Furthermore, in conjunction with Embodiment 1, the lifting platform includes a lifting column 23 and a lifting plate 24. The bottom of the lifting column 23 is fixedly connected to the ground, and the telescopic end of the lifting column 23 is fixedly connected to the lifting plate 24. A guide mechanism is installed on the upper part of the lifting plate 24. The lifting column 23 achieves vertical lifting movement through hydraulic or electric drive. Its bottom is fixed to the ground to ensure stability, and its telescopic end is rigidly connected to the lifting plate 24, driving the whole to move up and down. The guide mechanism installed on the upper part of the lifting plate 24 moves synchronously with the lifting plate 24. By precisely controlling the telescopic amount of the lifting column 23, the relative height between the ceramic product and the blade array can be adjusted to achieve accurate positioning of products of different thicknesses.

[0036] The guiding mechanism includes a linear drive rail 25 parallel to the knife unit 1. The linear drive rail 25 is fixedly mounted on the upper part of the lifting plate 24. A guide seat 26 is mounted on the linear drive rail 25. The linear drive rail 25 drives the guide seat 26 to move back and forth. A positioning rotary fixture is fixedly mounted on the guide seat 26.

[0037] In the above scheme, the linear drive guide rail 25 is installed parallel to the blade array on the lifting plate 24. The guide seat 26 is precisely reciprocated by the ball screw or synchronous belt driven by the servo motor. The positioning rotary fixture on the guide seat 26 can be adjusted along the guide rail direction to keep the ceramic product and the blade array in the best alignment state and ensure the accuracy of the cutting path.

[0038] The positioning rotary fixture includes a clamping base 28, inside which a friction roller 29 is installed to drive the ceramic to rotate. Inside the clamping base 28, a stepper motor is installed to drive the friction roller 29 to rotate. The friction roller 29 is made of rubber.

[0039] In the above scheme, the stepper motor in the clamping base 28 drives the rubber friction roller 29 to rotate, and the friction drives the ceramic product to rotate; the rubber friction roller 29 can provide sufficient driving force and avoid scratching the ceramic surface, and together with the movement of the multi-axis robotic arm 20, the ceramic product can be rotated and cut.

[0040] The clamping base 28 has a detachable positioning mold 31 installed inside. The upper surface of the positioning mold 31 is provided with a positioning groove 32 that is adapted to the ceramic curved surface. The friction roller 29 is installed on the upper part of the positioning groove 32 to drive the ceramic to rotate. Electric telescopic rods 35 are installed at both ends of the clamping base 28. The telescopic end of the electric telescopic rod 35 is equipped with an upper clamping plate 33. A driven roller 34 is installed on the side of the upper clamping plate 33 near the clamping base 28.

[0041] In the above scheme, the positioning mold 31 is installed in the clamping base 28 by a quick snap-fit. The positioning groove 32 of the positioning mold 31 is completely matched with the curved surface of the standard ceramic product. The electric telescopic rod 35 drives the upper clamping plate 33 to press down, and the driven roller 34 flexibly clamps the product, which not only ensures reliable fixation but also avoids damaging the product. By changing different positioning molds 31, different shaped ceramic products can be quickly adapted.

[0042] The working principle of the ceramic processing edge trimming device is as follows: First, the standard model ceramic product is placed on the positioning mold 31 of the positioning rotary fixture. The height is adjusted by the lifting column 23 of the lifting platform to initially align the curved surface of the product with the blade array. The electromagnetic coil array is energized to generate electromagnetic force, which pushes the magnetic drive part 4 of each small blade unit 1 to move along the rib groove 17, so that the flexible deformation of the blade array completely conforms to the contour of the ceramic curved surface. After the deformation is completed, the electric push rod 14 drives the strip tooth plate to press into the pressing groove of the small blade unit 1 for mechanical locking. After changing the product to be processed, the multi-axis robotic arm 20 drives the locked blade array to move along the preset trajectory. At the same time, the stepper motor drives the friction roller 29 to rotate the ceramic, so that the blade continuously contacts the edge of the product to complete the edge trimming. The cutting force is monitored in real time by the pressure sensor 22, and the control system dynamically adjusts the motion parameters of the robotic arm to ensure cutting accuracy. The entire processing process achieves high-precision adaptive edge trimming of complex curved ceramic products by first conforming to the shape and then cutting.

[0043] Although specific embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
