Description

Technical Field

[0001] The invention relates to the technical field of ceramic processing, in particular to a ceramic relief gold screen printing carving device. Background Art

[0002] Ceramic relief is made by various methods, such as piling, pasting, engraving, etc., to produce raised patterns on the ceramic surface. When the ceramic relief carving is completed, the raised patterns on its surface need to be printed using gold screen printing technology.

[0003] Before the ceramic relief carving, the pattern model to be carved is made by computer-aided design software, and the designed model is imported into the control software of the ceramic engraving machine. According to the specific size and requirements of the ceramic plate, the machine parameters, including speed, force, etc., are adjusted. According to the pattern model, the control software calculates the machine movement stroke and sets the initial point of the movement stroke, and the initial point needs to be aligned with the angle of the ceramic plate to ensure that the carved pattern can accurately match the size of the ceramic plate. In order to ensure the accuracy of the carving and avoid the pattern carved on the ceramic plate from being offset or tilted, it is necessary to first adjust the angle of the ceramic plate so that the length and width of the ceramic plate are parallel to the horizontal movement direction of the engraving machine.

When the limiting mechanism is respectively in a clamping state with the first transverse plate and the first vertical plate, the tip of the engraving tool is aligned with the clamping angle formed by the first transverse plate and the first vertical plate.

[0018] Technical effects and advantages of the present invention:

[0019] 1. The horizontal positioning mechanism and the vertical positioning mechanism of the present invention move together with the engraving knife through the limiting mechanism. The horizontal positioning mechanism and the vertical positioning mechanism clamp and limit the four ends of the ceramic plate during the movement, and can ensure that the engraving knife and the ceramic plate are positioned at an angle while clamping the four ends of the ceramic plate, so that the pattern engraved by the engraving knife is precisely matched with the size of the ceramic plate, avoiding the problem of mismatch between the engraved pattern and the ceramic plate due to inaccurate knife positioning, and through mechanical clamping and positioning, the positioning accuracy is improved, avoiding repeated positioning and debugging of the engraving knife.

[0020] 2. The limiting mechanism of the present invention connects the transverse positioning mechanism and the vertical positioning mechanism with the engraving tool, so that the three-axis moving platform provides clamping power for the transverse positioning mechanism and the vertical positioning mechanism. The limiting mechanism is used to limit the transverse positioning mechanism and the vertical positioning mechanism, so that the engraving tool is aligned with the clamping angle of the transverse positioning mechanism and the vertical positioning mechanism. The limiting mechanism also serves as a linkage structure for driving the transverse positioning mechanism and the vertical positioning mechanism to clamp. The limiting mechanism has the limiting function and is used to transmit the driving force of the three-axis moving platform to the transverse positioning mechanism and the vertical positioning mechanism, thereby reducing the drive, achieving rapid alignment and reducing the adjustment cost.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 8 , provides a ceramic relief gold screen printing carving equipment, including a processing table for placing a ceramic plate, and a three-axis mobile platform 2 is arranged above the processing table for driving a carving tool 3 to move along the X, Y, and Z axis directions, a horizontal positioning mechanism 4 and a vertical positioning mechanism 5 are arranged on the three-axis mobile platform 2, and a driving member for driving the three-axis mobile platform 2 to lift is arranged below the three-axis mobile platform 2. When the entire three-axis mobile platform 2 is lifted, the carving tool 3, the horizontal positioning mechanism 4 and the vertical positioning mechanism 5 connected thereto are all moved up, so that there is no obstruction on the processing table, which is convenient for loading the ceramic plate to be processed;

[0033] When the three-axis mobile platform 2 drives the engraving tool 3 to move along the X-axis toward the middle of the processing table, the first transverse plate 41 and the second transverse plate 42 approach each other along the X-axis direction to clamp the two ends of the ceramic plate. When the two ends of the ceramic plate are in a clamped state, when the three-axis mobile platform 2 drives the engraving tool 3 to move along the Y-axis direction, the first vertical plate 51 and the second vertical plate 52 approach each other along the Y-axis direction to clamp the other two ends of the ceramic plate. The four end faces of the ceramic plate are in a clamped state, and the four angles of the ceramic plate are respectively aligned with the four clamping angles formed by clamping the first transverse plate 41, the second transverse plate 42, the first vertical plate 51 and the second vertical plate 52.

[0034] The prior art uses two clamping plates moving toward each other to clamp and limit the two ends of the ceramic plate and adjust the inclination of the ceramic plate after placement, but can only adjust the position and angle of the ceramic plate separately, and cannot adjust the position and angle of the ceramic plate while aligning the angle between the engraving knife head and the ceramic plate. Compared with the prior art, the horizontal positioning mechanism 4 and the vertical positioning mechanism 5 in this solution move together with the engraving knife 3 through the limiting mechanism 6. The horizontal positioning mechanism 4 and the vertical positioning mechanism 5 clamp and limit the four ends of the ceramic plate during the movement, and while clamping the four ends of the ceramic plate It can ensure that the engraving tool 3 and the ceramic plate are positioned at an angle, which is convenient for accurately matching the pattern engraved by the engraving tool 3 with the size of the ceramic plate, avoiding the problem of mismatch between the engraved pattern and the ceramic plate due to inaccurate tool positioning, and through mechanical clamping positioning, the positioning accuracy is improved, avoiding repeated positioning and debugging of the engraving tool 3. The horizontal positioning mechanism 4 includes a first horizontal plate 41 and a second horizontal plate 42 that can approach or move away from each other along the X-axis direction, and the vertical positioning mechanism 5 includes a first vertical plate 51 and a second vertical plate 52 that can approach or move away from each other along the Y-axis direction.

[0035] The prior art needs to add a drive to drive the clamping plate to clamp and position the ceramic plate. Compared with the prior art, the limiting mechanism 6 in this solution connects the horizontal positioning mechanism 4 and the vertical positioning mechanism 5 with the engraving tool 3, so that the three-axis moving platform 2 provides the horizontal positioning mechanism 4 and the vertical positioning mechanism 5 with the clamping power. The limiting mechanism 6 is used for limiting the horizontal positioning mechanism 4 and the vertical positioning mechanism 5, so that the engraving tool 3 and the horizontal positioning mechanism 4 and the vertical positioning mechanism 5 are clamped at the same time. The limiting mechanism 6 also serves as a linkage structure for driving the horizontal positioning mechanism 4 and the vertical positioning mechanism 5 to clamp. The limiting mechanism 6 has a limiting function and is used to transmit the driving force of the three-axis moving platform 2 to the horizontal positioning mechanism 4 and the vertical positioning mechanism 5, reducing the drive, achieving rapid alignment and reducing the adjustment cost. The engraving tool 3 is connected to the three-axis moving platform 2 A limiting mechanism 6 is installed at the connecting end, and the limiting mechanism 6 is respectively clamped with the adjacent first transverse plate 41 and the first vertical plate 51. When the limiting mechanism 6 is in a clamping state with the first transverse plate 41 and the first vertical plate 51, the tip of the engraving tool 3 is aligned with the clamping angle formed by the first transverse plate 41 and the first vertical plate 51. When the limiting mechanism 6 moves downward along the Z axis, the limiting mechanism 6 releases the clamping state with the first transverse plate 41 and the first vertical plate 51. The limiting mechanism 6 is used to limit the distance between the engraving tool 3 and the first transverse plate 41 and the first vertical plate 51. In the clamping state, it can ensure that the tip of the engraving tool 3 is always aligned with the clamping angle of the first transverse plate 41 and the first vertical plate 51, and the clamping state can be released by moving the limiting mechanism 6 downward, so that the engraving tool 3 can be moved alone to carve the upper end surface of the ceramic plate.

[0036] When the three-axis mobile platform 2 drives the engraving tool 3 to move along the X-axis toward the middle of the processing table, the first transverse plate 41 and the entire vertical positioning mechanism 5 are driven to move along the X-axis toward the direction close to the second transverse plate 42 through the limiting mechanism 6, and the first transverse plate 41 and the second transverse plate 42 move toward each other. When the facing ends of the first transverse plate 41 and the second transverse plate 42 are in a clamping state with respect to the two ends of the ceramic plate, the three-axis mobile platform 2 drives the engraving tool 3 to move horizontally along the Y-axis direction, and the first vertical plate 51 and the transverse positioning mechanism 4 are driven to move along the Y-axis toward the direction close to the second vertical plate 52 through the limiting mechanism 6, and the first vertical plate 51 and the second vertical plate 52 move toward each other. When the facing ends of the first transverse plate 41 and the second transverse plate 42 are clamped with respect to the other two ends of the ceramic plate, the four end faces of the ceramic plate are in a clamping state, and the four angles of the ceramic plate are respectively aligned with the four angles formed by the clamping of the first transverse plate 41, the second transverse plate 42, the first vertical plate 51 and the second vertical plate 52, and the tip of the engraving tool 3 is aligned with one of the angles of the ceramic plate.

[0037] Both ends of the first transverse plate 41 and the second transverse plate 42 are extended and connected with connecting plates 421, and the connecting plates 421 at both ends of the first transverse plate 41 and the second transverse plate 42 are connected by two transverse driving components 43. The bottom ends of the opposite surfaces of the first transverse plate 41 and the second transverse plate 42 are connected with transverse clamping plates 422. The transverse driving component 43 includes a first mounting block 431 that is slidably connected to the inner wall of the three-axis mobile platform 2, and a threaded sleeve 432 is installed on the first mounting block 431 through a bearing, and a driving rod 433 installed on the connecting plates 421 at both ends of the first transverse plate 41, one end of the driving rod 433 is inserted in the threaded sleeve 432, and a threaded limiting groove 4321 is opened on the inner wall of the threaded sleeve 432, and a limiting column 4331 is installed at one end of the driving rod 433, and one end of the limiting column 4331 is inserted in the threaded limiting groove 4321. The connecting plates 421 at the ends are respectively sleeved on the two threaded sleeves 432. When the three-axis mobile platform 2 drives the engraving tool 3 to move along the X-axis toward the center of the processing table, the first transverse plate 41 and the entire vertical positioning mechanism 5 are driven to move along the X-axis toward the second transverse plate 42 through the limiting mechanism 6. When the first transverse plate 41 moves, the driving rods 433 on the connecting plates 421 at both ends thereof move into the threaded sleeve 432. The upper limit columns 4331 on the driving rod 433 cooperate with the threaded limit grooves 4321 on the inner wall of the threaded sleeve 432 to drive the threaded sleeve 432 to rotate. The connecting plates 421 at both ends of the second transverse plate 42 are matched with the threaded sleeve 432 through threads. The threaded sleeve 432 rotates to drive the second transverse plate 42 to move toward the first transverse plate 41, so that the first transverse plate 41 and the second transverse plate 42 move toward each other, which is used to clamp and limit the two ends of the ceramic plate.

[0038] Two vertical plates 521 are installed on the first vertical plate 51 and the second vertical plate 52. The vertical plates 521 of the first vertical plate 51 and the second vertical plate 52 are connected by two vertical drive components 53. The bottom ends of the opposite surfaces of the first vertical plate 51 and the second vertical plate 52 are connected with vertical clamping plates 522. The vertical drive component 53 has the same structure as the horizontal drive component 43. A U-shaped support plate 21 is installed on the outer wall of the three-axis mobile platform 2. One end of the vertical drive component 53 is slidably connected to the U-shaped support plate 21. When the opposite ends of the first horizontal plate 41 and the second horizontal plate 42 are in a clamping state against the two ends of the ceramic plate, the three-axis mobile platform 2 drives the engraving tool 3 to move horizontally along the Y-axis direction through the limit mechanism 6. The first vertical plate 51 and the transverse positioning mechanism 4 are driven to move along the Y-axis in the direction close to the second vertical plate 52. When the first vertical plate 51 moves, the vertical driving assembly 53 drives the first vertical plate 51 and the second vertical plate 52 to move toward each other. When the facing ends of the first transverse plate 41 and the second transverse plate 42 are clamped against the other two ends of the ceramic plate, the four end surfaces of the ceramic plate are in a clamping state, and when the limiting mechanism 6 moves downward to release the clamping state with the transverse positioning mechanism 4 and the vertical positioning mechanism 5, the transverse positioning mechanism 4 and the vertical positioning mechanism 5 are still in a clamping state, which is used to limit the ceramic plate to prevent the ceramic plate from being displaced when the engraving knife 3 is engraving the ceramic plate, thereby ensuring the stability of the ceramic plate during engraving.

[0039] The limiting mechanism 6 includes a right-angle plate 61 fixed at the connection between the engraving tool 3 and the telescopic rod, and a plurality of conical clamping columns 62 are arranged above the right-angle plate 61. Clamping plates 411 are arranged on the inner walls of the first horizontal plate 41 and the first vertical plate 51. Clamping holes 412 corresponding to the conical clamping columns 62 are opened on the two clamping plates 411. The setting of the conical clamping columns 62 improves the clamping stability, and the conical top end of the conical clamping column 62 is convenient for aligning and plugging with the clamping hole 412.
