DETAILED DESCRIPTION

[0019] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Among them, three protruding mounting plates 501 are evenly distributed and fixedly provided on the outer edge of the turntable 5 for mounting the workstation bracket 6 .

[0023] Among them, the work station bracket 6 includes a bearing seat 7, a support claw 8 and a driven wheel 9, the support claw 8 includes a support rod 801 and a plurality of claw blocks 802, the bearing seat 7 is fixedly installed on the mounting plate 501, the support rod 801 passes through the bearing seat 7 and is rotatably connected to the bearing seat 7, the claw block 802 is fixedly set on the top of the support rod 801, and the driven wheel 9 is fixedly set on the bottom of the support rod 801.

[0024] Among them, there are four claw blocks 802 and they are evenly distributed on the top of the support rod 801 to form a conical support space. The angle α of the support surface 803 relative to the two claw blocks 802 is in the range of 150-160 degrees. The support surface 802 is used to support the base of the ceramic piece (each ceramic piece has a circle at the bottom for supporting the base of the ceramic piece. The base does not need to be sprayed with glaze to prevent the ceramic piece from slipping and breaking when placed on the table due to being too smooth). The setting of the conical support space can expose the bottom of the ceramic piece, making it convenient for the glaze spraying robot 3 to spray glaze on the bottom of the ceramic piece. The support surface 803 is provided with serrated stripes to increase the friction with the base.

[0025] Among them, the outer circles of the driven wheel 9 and the driving wheel 11 are both provided with a rubber layer, and the rubber layer is provided with splines. The rubber layer is elastic, so that the turntable 5 drives the driven wheel 9 to elastically contact with the driving wheel 11, so that the splines on the driven wheel 9 and the driving wheel 11 are well meshed, thereby driving the supporting claws 8 and the ceramic parts to rotate.

[0026] Among them, the glaze spraying robot 3 model is universal robots UR5 / CB3.

[0027] The glaze spraying cabinet 2 is provided with a dust removal device to optimize the glaze spraying environment.

[0028] Working principle of this utility model:

[0029] The operator first places the ceramic parts on the three supporting claws 8 respectively, and starts the station rotating motor 4. The station rotating motor 4 drives the turntable 5, the driven wheel 9, the supporting claws 8, and the ceramic parts to rotate slowly around the central axis of the turntable. When the driven wheel 9 located at station A contacts and engages with the driving wheel 11, the station rotating motor 4 stops rotating, and the bracket rotating motor 10 starts to drive the driving wheel 11 to rotate slowly. The driving wheel 11 drives the driven wheel 9, the supporting claws 8, and the ceramic parts to rotate slowly around the axis of the driven wheel 9. The glaze spraying robot 3 sprays glaze on the ceramic parts according to the preset program. After the glaze spraying is completed, the bracket rotating motor 10 stops, and the station rotating motor 4 starts and drives the turntable 5, the driven wheel 9 , supporting claws 8, and ceramic pieces slowly rotate around the central axis of the turntable. When the driven wheel 9 at station B contacts and engages with the driving wheel 11, similarly, the ceramic piece at station B slowly rotates around its own axis, and the glaze spraying robot 3 works on glazing. At this time, the ceramic piece at the original station A has rotated to station C. The operator removes the glazed ceramic piece and places another ceramic piece to be glazed on the supporting claws 8, realizing the turntable-type three-station flow and the coordinated operation of the glaze spraying robot 3 to complete the automatic glazing operation, achieving differential stepping operation, thereby controlling the uniformity and accuracy of glazing, ensuring product quality, reducing the difficulty and intensity of workers' glazing work, and greatly improving production efficiency.
