[0022] The gypsum mold design in the present invention is intelligent and flexible. According to the principle of topological homeomorphism, the gypsum mold is abstracted into a sphere and then evolved into a cube to form six mold pieces. At the same time, the displacement of each mold piece is arranged according to the radial direction from the center of the sphere to the outside. Theoretically, interference and collision that may occur during the opening and closing of the connecting working surfaces between the mold pieces can be avoided to the greatest extent. The joint surface is finely matched and the transition is subtle, which not only improves the quality of the blank making, but also increases the service life of the mold piece. By matching different gypsum mold pieces, the same gypsum module group can have gypsum molds with different cavities, and ceramic blanks of different shapes can be produced in one process, thereby realizing the flexible production of gypsum molds.

The telescopic cylinder 29 is arranged above the workbench 18, and the end of the telescopic cylinder 29 is provided with a connector 30 for detachable connection with the top of the fixed crown. The mold opening and closing component 45 includes four groups of opening and closing side mold devices 31 and two groups of opening and closing upper mold devices 32. The four groups of opening and closing side mold devices 31 are respectively arranged at the front and rear parts of both sides of the guide groove 21 to correspond to the four side mold pieces 9, and the two groups of opening and closing upper mold devices 32 are respectively arranged at the middle parts of both sides of the guide groove 21 for clamping the upper mold piece. The opening and closing side mold device 31 includes a first driver 33 and a coupling The connecting claw 34, the opening and closing upper mold device 32 includes a second driver 35, a third driver 36 and a grab plate 37.

[0038] When opening and closing the mold, first, after the accompanying plate 5 enters the guide groove 21, the unlocking device at the bottom first unlocks the clamping assembly at the bottom of the fixed crown 3, and then the piston rod of the telescopic cylinder 29 above descends to connect the connector 30 on it with the fixed crown 3, and then the piston rod lifts the fixed crown 3, and the plaster mold is exposed to the outside.

After taking the blank, the mold can be closed according to the above principle.

[0039] See also Figure 6As shown, the blank taking robot 46 includes a robot arm and an execution assembly connected to the end of the robot arm, and the execution assembly includes a gripper 38, a push rod 39 and a support plate 40 from top to bottom.

[0040] The blank has not been fully solidified, and its strength and rigidity are very low. It is easy to deform and damage when subjected to a little force, and cannot be grasped when subjected to a little force. Efficient and safe picking is another major technical challenge to realize the intelligent and flexible production line. The specially designed picking robot (manipulator) of the present invention designs the grabbing and transfer end effector according to the strength, wall thickness and weight of the blank. Based on experiments and statistics, multiple pressure sensors are set on the gripper 38 and arranged in a "plum blossom pile" manner. The contact pressure of the gripper 38 is optimized by a uniform algorithm, and an auxiliary support plate 40 is set at the same time to jointly complete the grabbing and transfer of the blank;

[0041] The gripper 38 is equipped with a level sensor and a pressure sensor to ensure that the contact stress and the gripping pressure of the gripper 38 when contacting the ceramic blank are within a safe range; the support plate 40 is used to assist the gripping and ensure that the main gripping force is not too large, so as not to cause deformation or damage to the blank. The support plate 40 is made into a small wedge angle, , which is convenient for guiding the bottom of the blank; the purpose of using the "pushing rod 39" is to sense the relative position of the blank and make the blank tilt at a small angle. , so that the support plate 40 can enter under the blank.

[0042] See also Figure 1 As shown, the grouting assembly includes a grouting frame 41, a ceramic slurry mixing station 42 and a plurality of grouting heads 43. The grouting frame 41 is installed on the top of the machine body 1, and the ceramic slurry mixing station 42 is arranged above the grouting frame 41. A plurality of grouting heads 43 are arranged at equal intervals on the front end surface of the grouting frame 41, and the output end of the ceramic slurry mixing station 42 is connected to each grouting head 43 through a pipeline.

[0043] The working principle of the present invention is as follows:

[0044] The present invention designs a "large cycle of the conveying mechanism circulating the gypsum mold" and a "small cycle of the blank conveying mechanism circulating the mold opening and closing" to form a production line for grouting blanks to manufacture ceramic handicrafts. During production, the gypsum mold on the bracket 4 is driven by the conveying mechanism to move, and when the gypsum mold is transported to the grouting assembly, the grouting head 43 is used to pour slurry into each gypsum mold. After the grouting is completed, the gypsum mold continues to be transported forward, and during the transportation process, the slurry in the gypsum mold absorbs the molded blank. When it is transported to the slurry cleaning area, the motor at the side end of the bracket 4 drives the bracket 4 to tilt, thereby dumping excess mud in the gypsum mold.

[0045] After the gypsum module is cleared of slurry and reset, it is continuously transported to the blank-taking conveying mechanism to prepare for the small cycle blank-taking. The first group of transverse movement mechanisms 19 first drives the gypsum module to move forward to the "opening, taking and closing array position" in the workbench 18 to perform "mold opening", "brick taking" and "mold closing" operations. In the small cycle, after a group of gypsum modules completes "mold opening", "brick taking" and "mold closing", the swing mechanism completes the "transverse movement" and enters the second spatial position of the guide groove 21; and the subsequent gypsum module in the same array - the second gypsum module is driven by the first group of transverse movement mechanisms 19 to move forward to the "opening, taking and closing array position" to perform "mold opening", "brick taking" and "mold closing" operations. When the second group of gypsum modules moves forward, the first group of gypsum modules that are already in the second spatial position of the gypsum module array are driven by the displacement mechanism 20 to move horizontally to the third spatial position of the guide groove 21, and then driven by the second group of transverse movement mechanisms 19 to move forward back to the bracket 4, leaving the small cycle and entering the large cycle for reuse.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
