Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Example: Reference Figures 1-12 An automated ceramic surface pattern spraying device includes a base frame 101, on which a support assembly and a pressing assembly are mounted. Both the support assembly and the pressing assembly include an auxiliary circular plate 113. A support ring plate 102 and a pressing ring plate 106 are fixedly mounted on the base frame 101, with their axes aligned. The auxiliary circular plate 113 in the support assembly is rotatably mounted on the support ring plate 102, and a lowering ring plate 135 is rotatably mounted on the pressing ring plate 106. The auxiliary circular plate 113 in the pressing assembly is slidably mounted on the lowering ring plate 135. On the ring plate 135, a gear set is provided between the auxiliary circular plate 113 in the support assembly and the lowering ring plate 135. A lowering screw 134 is fixedly installed on the auxiliary circular plate 113 in the pressing assembly. A lowering pulley 136 is rotatably installed on the lowering ring plate 135. The lowering pulley 136 and the lowering screw 134 form a helical pair. A lowering motor 137 is fixedly installed on the lowering ring plate 135. A pulley is fixedly installed on the output shaft of the lowering motor 137. A lowering belt 138 is provided between the pulley on the output shaft of the lowering motor 137 and the lowering pulley 136.

[0029] The gear set includes two synchronous gears 108 and two synchronous gear rings 109. The two synchronous gears 108 are rotatably mounted on the support ring plate 102 and the pressing ring plate 106, respectively, and are fixedly connected to each other. The two synchronous gear rings 109 are fixedly mounted on the auxiliary circular plate 113 and the lowering ring plate 135 in the support assembly, respectively. The synchronous gears 108 and the corresponding synchronous gear rings 109 mesh to form a gear pair. A synchronous motor 107 is fixedly mounted on the pressing ring plate 106, and the output shaft of the synchronous motor 107 is fixedly connected to the corresponding synchronous gear 108.

[0030] The pressing ring plate 106 is located directly above the support ring plate 102, meaning the pressing assembly is located directly above the support assembly. When the downward moving motor 137 is started, the downward moving pulley 136 rotates under the action of the downward moving belt 138. Under the action of the downward moving screw 134, the auxiliary circular plate 113 in the pressing assembly moves up and down relative to the base frame 101. The synchronous motor 107 is started to drive the corresponding synchronous gear 108 to rotate. The two synchronous gears 108 rotate synchronously, which in turn causes the two synchronous gear rings 109 to rotate synchronously, so that the auxiliary circular plate 113 in the support assembly and the downward moving ring plate 135 rotate synchronously, and so that the two auxiliary circular plates 113 rotate synchronously.

[0031] Auxiliary circular blocks 118 are fixedly installed on each auxiliary circular plate 113. Supporting circular rods 123 are fixedly installed on each auxiliary circular plate 113. Auxiliary circular blocks 118 are fixedly installed on the end of the supporting circular rod 123 furthest from the auxiliary circular plate 113. Annular support plates 110 are slidably installed on each auxiliary circular plate 113. A clearance screw 114 is fixedly installed on the annular support plate 110. A clearance pulley 115 and a transmission pulley 117 are rotatably installed on each auxiliary circular plate 113. A transmission belt 116 is provided between the clearance pulley 115 and the transmission pulley 117. The clearance pulley 115 and the corresponding clearance screw 114 form a helical pair. A clearance motor 124 is also fixedly installed on each auxiliary circular plate 113. The output shaft of the clearance motor 124 is fixedly connected to the corresponding transmission pulley 117.

[0032] The start-up motor 124 drives the corresponding transmission pulley 117 to rotate. Under the action of the transmission belt 116, the yield pulley 115 rotates synchronously. Then, under the action of the yield screw 114, the annular support plate 110 moves up and down relative to the auxiliary circular plate 113.

[0033] Multiple auxiliary ring plates 119 are evenly arranged between the auxiliary circular block 118 and the corresponding annular support plate 110. The multiple auxiliary ring plates 119 are arranged sequentially between the annular support plate 110 and the auxiliary circular block 118. The difference between the inner and outer radii of each auxiliary ring plate 119 is equal. When the upper surfaces of the annular support plate 110, the corresponding auxiliary circular block 118, and the auxiliary ring plate 119 are on the same plane, a complete circular plate is formed. Each auxiliary ring plate 119 is provided with a stepped surface. The stepped surface on the auxiliary ring plate 119 is used to limit the position between the auxiliary circular block 118 and the auxiliary ring plate 119. The axes of the annular support plate 110, the auxiliary circular plate 113, the auxiliary circular block 118, and the auxiliary ring plate 119 are on the same straight line.

[0034] A symmetrical sliding adjustment slider 129 is mounted on the auxiliary circular plate 113. A tension spring is provided between the adjustment slider 129 and the auxiliary circular plate 113. One end of the tension spring is fixedly connected to the auxiliary circular plate 113, and the other end of the tension spring is fixedly connected to the corresponding adjustment slider 129. A support rod 120 is fixedly provided on each adjustment slider 129. The support rod 120 is used to limit the position of the auxiliary ring plate 119. An adjustment ring plate 127 is also rotatably mounted on the auxiliary circular plate 113. Two arc-shaped strips 128 are fixedly arranged in a circular array on the adjustment ring plate 127. The arc-shaped strips 128 are used to push the corresponding support rods 120 to move.

[0035] In the initial position, the tension springs between the adjusting slider 129 and the auxiliary circular plate 113 are not stretched. At this time, the two adjusting sliders 129 on the same auxiliary circular plate 113 are at the farthest positions, which means that the two corresponding support rods 120 are at the farthest positions. At this time, the end face of the support rod 120 that is farthest from the corresponding auxiliary circular plate 113 is in contact with the surface of the auxiliary ring plate 119 that is farthest from the axis of the annular support plate 110. Under the action of the support rod 120, the auxiliary ring plate 119 cannot move relative to the auxiliary circular block 118. Under the action of the stepped surface on the auxiliary ring plate 119, all the auxiliary ring plates 119 cannot move relative to the auxiliary circular block 118.

[0036] The drive adjustment ring plate 127 rotates, and the two arc-shaped strips 128 on the adjustment ring plate 127 rotate synchronously. Under the action of the arc-shaped strips 128, the two support rods 120 move towards each other, and the two adjustment sliders 129 move towards each other. The tension spring between the adjustment sliders 129 and the auxiliary circular plate 113 is stretched, which causes the support rods 120 to move to the end face of the support rod 120 that is furthest from the auxiliary circular plate 113 and the second furthest from the axis of the auxiliary circular block 118. When the auxiliary ring plate 119 is in contact with the auxiliary ring plate 118, the auxiliary ring plate 119 furthest from the axis of the auxiliary ring block 118 can move relative to the other auxiliary ring plates 119. At this time, the auxiliary ring plate 119 inside the second furthest auxiliary ring plate 119 from the axis of the auxiliary ring block 118 cannot move relative to the auxiliary ring block 118. When the end face of the support rod 120 furthest from the auxiliary ring plate 113 is in contact with the surface of the auxiliary ring block 118, all auxiliary ring plates 119 can move relative to the auxiliary ring block 118.

[0037] A snap-fit ​​sliding plate 133 is symmetrically slidably mounted on the annular support plate 110. A sliding groove that mates with the snap-fit ​​sliding plate 133 is symmetrically set on the auxiliary annular plate 119. An adjustable sliding plate 122 is symmetrically slidably mounted on the auxiliary circular plate 113. A spring is provided between the adjustable sliding plate 122 and the auxiliary circular plate 113. A linkage strip 121 is fixedly mounted on the snap-fit ​​sliding plate 133. The linkage strip 121 slides and mates with the corresponding adjustable sliding plate 122. Two arc-shaped strips 126 are fixedly arranged in a circular array on the adjustable annular plate 127. An adjustable short column 125 is fixedly set on each of the adjustable sliding plates 122. The arc-shaped strips 126 are used to push the corresponding adjustable short column 125 to move.

[0038] In the initial position, the springs between the adjusting slide plate 122 and the auxiliary circular plate 113 are not compressed, and the two adjusting slide plates 122 are at the farthest position. Under the action of the linkage plate 121, the two locking slide plates 133 are at the farthest position. At this time, neither of the locking slide plates 133 is in contact with the auxiliary ring plate 119.

[0039] As the adjusting ring plate 127 rotates, the two arc-shaped strips 126 also rotate synchronously. Under the action of the adjusting short column 125, the two adjusting slide plates 122 move towards each other. The spring between the adjusting slide plate 122 and the auxiliary circular plate 113 is compressed. Then, under the action of the linkage strip 121, the two locking slide plates 133 move towards each other. When the end face of the support rod 120 furthest from the auxiliary circular plate 113 contacts the auxiliary ring plate 119, which is the second furthest from the axis of the auxiliary circular block 118, the locking slides... Plate 133 engages with the groove on the auxiliary ring plate 119, which is furthest from the axis of the auxiliary block 118. At this time, the driving ring support plate 110 moves toward the corresponding auxiliary ring plate 113. Under the action of the locking slide plate 133, the auxiliary ring plate 119, which is furthest from the axis of the auxiliary block 118, moves synchronously. There is friction between the locking slide plate 133 and the auxiliary ring plate 119. Therefore, when the auxiliary ring plate 119 and the ring support plate 110 move synchronously, the auxiliary ring plate 119 will not move relative to the locking slide plate 133.

[0040] When the position of the support rod 120 is adjusted, the position of the locking slide plate 133 changes synchronously. When the support rod 120 contacts the auxiliary block 118, the locking slide plate 133 engages with the grooves on all the auxiliary ring plates 119 corresponding to the locking slide plate 133. Under the action of the locking slide plate 133, when the annular support plate 110 moves, the auxiliary ring plates 119 corresponding to the annular support plate 110 all move synchronously.

[0041] When the annular support plate 110 moves relative to the auxiliary circular plate 113, the linkage plate 121 slides relative to the corresponding adjustable sliding plate 122.

[0042] An adjusting gear ring 130 is fixedly installed on the adjusting ring plate 127, and an adjusting motor 132 is also fixedly installed on the auxiliary circular plate 113. An adjusting gear 131 is fixedly installed on the output shaft of the adjusting motor 132. The adjusting gear 131 meshes with the corresponding adjusting gear ring 130 to form a gear pair. When the adjusting motor 132 is started, it drives the adjusting gear 131 to rotate, so that the adjusting gear ring 130 rotates. The adjusting ring plate 127 corresponding to the adjusting gear ring 130 rotates synchronously, thereby causing the two arc-shaped strips 126 and 128 on the adjusting ring plate 127 to rotate synchronously.

[0043] An adjustment assembly is provided on the base frame 101. The adjustment assembly includes an adjustment ring plate 103, which is slidably mounted on the base frame 101. An adjustment screw 105 is rotatably mounted on the base frame 101. An adjustment motor 104 is fixedly mounted on the base frame 101. The output shaft of the adjustment motor 104 is fixedly connected to the adjustment screw 105. The adjustment screw 105 and the adjustment ring plate 103 form a helical pair. The axes of the support ring plate 102 and the adjustment ring plate 103 are on the same straight line. Three adjustment strips 111 are movably arranged in a circular array on the adjustment ring plate 103. The adjustment strips 111 are used to adjust the position of the ceramic. A nozzle 146 is also provided on the adjustment ring plate 103.

[0044] Three adjusting racks 112 are slidably mounted in a circular array on the adjusting ring plate 103. Adjusting racks 111 are fixedly mounted on the corresponding adjusting racks 112 at the ends closest to the axis of the adjusting ring plate 103. A gear set two is arranged between the three adjusting racks 112. The gear set two includes a centering ring 142, three centering gears 140, and three driven gears 141. The three centering gears 140 are rotatably mounted in a circular array on the adjusting ring plate 103. The driven gears 141 are fixedly mounted on the corresponding centering gears 140. The centering gears 140 and the corresponding adjusting racks 112 mesh to form a gear rack pair. The centering ring 142 is rotatably mounted on the adjusting ring plate 103. The driven gears 141 all mesh with the centering ring 142 to form a gear pair. A centering motor 139 is also fixedly mounted on the adjusting ring plate 103. The output shaft of the centering motor 139 is fixedly connected to the corresponding centering gear 140.

[0045] In the initial position, the adjusting ring plate 103 is located closest to the support ring plate 102, and the annular support plate 110 corresponding to the support ring plate 102 is located closest to the pressing ring plate 106. At this time, the upper surfaces of the annular support plate 110, the auxiliary round block 118, and the auxiliary ring plate 119 in the support assembly are on the same plane, and the upper surface of the centering toothed ring 142 is located below this plane, which facilitates the placement of the ceramic to be sprayed on this plane.

[0046] In the initial position, all three adjusting plates 111 are located at the position furthest from the axis of the centering gear ring 142. At this time, the adjusting plates 111 are all located outside the annular support plate 110, meaning that the adjusting plates 111 will not affect the movement of the annular support plate 110. The centering motor 139 is started to drive the corresponding centering gear 140 to rotate. The driven gear 141 on the centering gear 140 rotates synchronously. Under the action of the centering gear ring 142, all three centering gears 140 and three driven gears 141 rotate synchronously, so that the adjusting rack 112 moves towards the axis of the adjusting ring plate 103, thereby causing the three adjusting plates 111 to move synchronously towards the axis of the adjusting ring plate 103.

[0047] When the lowering ring plate 135 is at its farthest position from the support ring plate 102 and the two annular support plates 110 are at their closest positions, the distance between the two annular support plates 110 and the length of the adjusting strip 111 are equal.

[0048] When the lowering ring plate 135 is at its furthest position from the supporting ring plate 102 and the two annular supporting plates 110 are at their furthest positions, the ceramic to be sprayed is placed on the plane formed by the annular supporting plate 110, the auxiliary circular block 118, and the auxiliary ring plate 119 in the supporting assembly. Then, the adjusting motor 104 is started to drive the adjusting screw 105 to rotate, causing the adjusting ring plate 103 to move upward, so that the adjusting strips 111 also move upward, so that the upper end surface of the adjusting strips 111 and the ring in the pressing assembly are aligned. The lower surface of the support plate 110 is on the same plane. At this time, the lower end face of the adjusting strip 111 and the upper surface of the annular support plate 110 in the support assembly are on the same plane. Then, the centering motor 139 is started to move the three adjusting strips 111 toward the axis of the adjusting ring plate 103. Under the action of the three adjusting strips 111, the position of the ceramic on the support assembly is adjusted, so that the center line of the ceramic and the axis of the annular support plate 110 are on the same straight line, that is, the position of the ceramic is adjusted.

[0049] A feed screw 143 is slidably mounted on the adjusting ring plate 103, and a feed slide plate 145 is rotatably mounted on the adjusting ring plate 103. The end of the feed screw 143 furthest from the axis of the adjusting ring plate 103 forms a helical pair with the feed slide plate 145. A feed motor 144 is fixedly mounted on the adjusting ring plate 103. The output shaft of the feed motor 144 is fixedly connected to the feed slide plate 145. A nozzle 146 is fixedly mounted on the end of the feed screw 143 closest to the axis of the adjusting ring plate 103.

[0050] In the initial position, the feed screw 143 is located at the position farthest from the axis of the adjusting ring plate 103, that is, the nozzle 146 is located at the position farthest from the axis of the adjusting ring plate 103. The nozzle 146 is located on the outside of the annular support plate 110. The feed motor 144 is started to drive the feed slide plate 145 to rotate, so that the feed slide plate 145 moves towards the axis of the adjusting ring plate 103, and the nozzle 146 moves towards the axis of the adjusting ring plate 103 in sync.

[0051] After the adjustment plate 111 completes the position adjustment of the ceramic on the support assembly, the feed motor 144 is started to move the nozzle 146 closer to the ceramic. The nozzle 146 is used to spray the ceramic surface. The adjustment motor 104 is started to adjust the position of the nozzle 146 relative to the ceramic, and the two auxiliary circular plates 113 rotate synchronously to achieve complete spraying of the ceramic surface.

[0052] Working principle: The ceramic to be sprayed is placed on the support plane formed by the annular support plate 110, auxiliary circular block 118 and auxiliary ring plate 119 in the support assembly. Then, the adjustment motor 104 is started to adjust the position of the adjustment strip 111. Then, the centering motor 139 is started to move the three adjustment strips 111 toward the axis of the centering gear ring 142. Under the action of the three adjustment strips 111, the position of the ceramic is adjusted.

[0053] Then, based on the minimum diameter of the inner side of the ceramic, the pitch motor 132 is started to drive the pitch ring plate 127 to rotate. Under the action of the arc-shaped strip plate 128 and the pitch slider 129, the lower end face of the support rod 120 in the pressing assembly contacts the auxiliary ring plate 119, which is slightly smaller than the minimum diameter of the inner side of the ceramic. Under the action of the linkage strip plate 121, the pitch sliding plate 122, the pitch short column 125, and the arc-shaped strip plate 126, the locking sliding plate 133 engages with the groove on the other auxiliary ring plates 119 located outside the auxiliary ring plate 119.

[0054] Then, the push-off motor 124 in the pressing assembly is activated, causing the annular support plate 110 in the pressing assembly to move upward. Under the action of the auxiliary circular plate 113, the auxiliary ring plates 119, which are larger than the minimum diameter of the inner side of the ceramic, move upward synchronously. Finally, the annular support plate 110 moves to the position furthest from the support ring plate 102. Then, the downward moving motor 137 is activated, causing the auxiliary circular plate 113 and the downward moving screw 134 in the pressing assembly to move downward synchronously. This causes the auxiliary circular block 118 in the pressing assembly to move downward synchronously, and the auxiliary ring plates 119, which are on the same plane as the auxiliary circular block 118, to move downward synchronously. This causes the auxiliary circular block 118 and this part of the auxiliary ring plates 119 to move to the inside of the ceramic through the position of the minimum diameter of the ceramic. Finally, the lower surfaces of the auxiliary circular block 118 and this part of the auxiliary ring plates 119 are in contact with the inner bottom surface of the ceramic. That is, under the action of the pressing assembly, the ceramic is fixed. Then, the three adjusting strips 111 are moved to the position furthest from the axis of the centering toothed ring 142.

[0055] At this point, the ceramic is in a fixed state. Then, based on the diameter of the bottom surface of the ceramic, the pitch motor 132 is started to drive the pitch ring plate 127 to rotate. Under the action of the arc-shaped strip plate 128 and the pitch slider 129, the upper end face of the support rod 120 in the support assembly contacts the auxiliary ring plate 119 that is furthest from the axis of the auxiliary circular block 118 in contact with the ceramic. Under the action of the linkage strip plate 121, the pitch sliding plate 122, the pitch short column 125, and the arc-shaped strip plate 126, the locking sliding plate 133 engages with the groove on the other auxiliary ring plates 119 located outside the auxiliary ring plate 119. Then, the clearance motor 124 in the support assembly is started, causing the annular support plate 110 in the support assembly to move downward. The auxiliary ring plates 119 engaged by the locking sliding plate 133 all move downward synchronously, finally causing the annular support plate 110 and this part of the auxiliary ring plates 119 to move to the position furthest from the pressing ring plate 106.

[0056] At this time, the annular support plate 110 and the unused auxiliary ring plate 119 in the support assembly and pressing assembly make way for the nozzle 146 to spray the ceramic, thereby facilitating the nozzle 146 to spray the ceramic surface.

[0057] Then, the synchronous motor 107 is started, so that the two auxiliary circular plates 113 rotate, which in turn causes the two auxiliary circular blocks 118 to rotate synchronously, so that the ceramic rotates relative to the nozzle 146. Then, the feed motor 144 and the position adjustment motor 104 are started to adjust the position of the nozzle 146. Under the action of the nozzle 146, the spraying of the ceramic surface pattern is completed.

[0058] After the spraying is completed, repeat the above steps in reverse to release the pressing component from fixing the ceramic.

[0059] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
