[0023] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings of specific embodiments. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0024] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the field to which the present utility model belongs. "Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0025] Combined with Figures 1 to 2As shown in the figure, a grouting robot workstation for a toilet body includes two sets of symmetrically arranged body forming units, a hydraulic pump station, an air compressor, and a vacuum pump that support and serve the body forming units. Each forming unit includes multiple vertical grouting molding machines, which are used to form different body parts in a single toilet. Here, the vertical grouting molding machine is a vertically mold-opening vertical grouting molding machine, and each is at least provided with its own upper mold and lower mold. The inner wall of the mold cavity of the mold in the vertical grouting molding machine is provided with a resin layer with micropores. The side of the resin layer away from the mold cavity is connected to the air compressor and the vacuum pump through pipes and control valves, which is used to assist mold opening and body demolding. The multiple vertical grouting molding machines in each forming unit are specifically an inner tank molding machine 4, an outer shell molding machine 5, and a seat ring molding machine 6. Multiple body parts for assembling a single toilet can be grouted and molded in the same set of forming units. There is a multi-joint robot 1 between the two sets of forming units. A transporting bracket 9 is connected to the end joint of the robotic arm of the multi-joint robot 1. The upper part of the bracket 9 is provided with an elastic buffer part, and here the elastic buffer part can be a spring or an airbag to achieve a buffering effect. On one side of the movement range of the multi-joint robot 1, there is a blank storage rack 2. The blank storage rack 2 is an overhead frame structure. The blank storage rack 2 is provided with multiple side-by-side blank placement positions. On the side of the blank storage rack 2 away from the multi-joint robot 1, there are multiple groups of fans 20. The fans 20 are arranged opposite to the blank placement positions. By setting the fans 20, the drying of the surface of the blanks during temporary storage can be accelerated.

[0026] There is a blank trimming table 10 under the blank storage rack 2. Combining Figure 3 As shown in the figure, the blank trimming table 10 includes a fixed frame 101 at the bottom and a placement frame 102 at the top. There is a lifting drive mechanism between the fixed frame 101 and the placement frame 102. The lifting drive mechanism includes a lifting drive cylinder 1010. The cylinder barrel of the lifting drive cylinder 1010 is fixed in the fixed frame 101. The top of the lifting rod of the lifting drive cylinder 1010 is provided with a lifting platform 103. The placement frame 102 is rotatably connected to the upper side of the lifting platform 103. There are guide columns 1011 that slide relative to each other between the lifting platform 103 and the fixed frame 101.

[0027] During use, combining Figures 3 to 4 As shown in the figure, before placing the blank on the placement frame 102, first control the placement frame 102 to rise with the lifting platform 103. The multi-joint robot 1 places the profiling plate 90 in the placement frame 102 through the bracket 9. When the bracket 9 disengages from contact with the placement frame 102, control the placement frame 102 to descend. After descending, the operator can conveniently trim the blank. Since the robotic arm of the multi-joint robot 1 is above the operator's activity range during the above actions, the safety can be improved and personal injury can be avoided.

[0028] Combining Figures 5 to 7As shown in the figure, when a wall-mounted toilet needs to be produced, since the sewage outlet is arranged at the rear side of the toilet, a rear plug mold 55 needs to be arranged in the mold, and the opening / closing mold action of the rear plug mold 55 needs to be added. In this case, the outer sleeve molding machine 5 here includes a fixedly arranged bracket 51. A connecting frame 52 is rotatably arranged at the upper part of the bracket 51. A lower convex mold 53 is arranged at the bottom of the connecting frame 52. An upper concave mold 54 is vertically slidably arranged at the top of the connecting frame 52. A top closing mold oil cylinder 56 and a guiding mechanism 561 are connected between the upper concave mold 54 and the top of the connecting frame 52. A rear plug mold 55 is arranged at the rear side of the upper concave mold 54. A rear top frame 541 is fixedly arranged outside the corresponding side of the upper concave mold 54 and the rear plug mold 55. A rear oil cylinder 57 is arranged in the middle of the rear top frame 541. The end of the extending rod of the rear oil cylinder 57 is connected to the rear plug mold 55. A V-shaped guiding frame 551 is arranged at the rear part of the rear plug mold 55. Guide rods 552 are respectively fixed on the left and right sides of the V-shaped guiding frame 551. Guide sleeves 542 are respectively fixed on the left and right sides of the rear top frame 541. The guide rods 552 are slidably connected in the guide sleeves 542. The length direction of the guide rods 552 is parallel to the opening / closing mold direction of the rear plug mold 55. During use, the opening or closing of the rear plug mold 55 can be realized through the arranged rear oil cylinder 57. Since the rear oil cylinder 57 is installed in the upper concave mold 54, the movement of the upper concave mold 54 can drive the rear oil cylinder 57 and the rear plug mold 55 to move simultaneously.

[0029] Combined with Figures 1 to 2 and Figure 8 As shown in the figure, a conveyor line 7 is arranged on the lower side of the blank storage rack 2. A processing line 3 is arranged downstream of the conveyor line 7. A blank turning machine 8 is arranged between the conveyor line 7 and the processing line 3. A return plate mechanism is arranged on one side of the blank turning machine 8. Combined with Figure 8 As shown in the figure, the return plate mechanism includes a return plate lifting machine 71 and a return plate conveyor chain 70. The return plate conveyor chain 70 is arranged in parallel at the lower part of the conveyor line 7. The return plate lifting machine 71 is arranged at the same end of the conveyor line 7 and the return plate conveyor chain 70.

[0030] During use, the inner liner molding machine 4, the outer sleeve molding machine 5 and the seat ring molding machine 6 each perform grouting. The seat ring molding machine 6 first completes grouting and controls the upper mold to open upward. The corresponding upper mold adsorbs and holds the formed blank in the upper mold cavity under the action of vacuum pumping. The multi-joint robot 1 holds a profiling support plate 90 through a bracket 9 at the end of the return plate conveyor chain 70, and moves the profiling support plate 90 to the lower side of the upper mold of the seat ring molding machine 6. The profiling support plate 90 keeps an appropriate distance from the ring blank. At this time, the pipeline connection between the upper mold and the vacuum pumping machine is disconnected and connected to an air compressor, and the ring blank is blown downward to make the ring blank fall onto the profiling support plate 90. The multi-joint robot 1 places the profiling support plate 90 and the ring blank on the blank repairing table 10. After that, the seat ring molding machine 6 can enter the next cycle for grouting, and operations such as manual blank repairing can be carried out here.

[0031] After the inner tank forming machine 4 grouts to the set time, the multi-joint robot 1 automatically picks the corresponding profiling pallet 90 and the ring blank to the slurry coating nozzle for slurry coating. Then, it controls the mold opening oil cylinder in the inner tank forming machine 4 to drive the upper mold and the side molds on both sides to rise. Here, the inner tank mold is divided into an upper mold, a lower mold, and two side molds. The multi-joint robot 1 drives the ring blank coated with slurry into the inner tank forming machine 4 after mold opening. The ring blank contacts the inner tank blank, and the multi-joint robot 1 stops moving and waits for the bonding delay. Blowback is performed for demolding the inner tank blank, and the side molds of the inner tank forming machine 4 are controlled to open to both sides. The inner tank blank is completely demolded onto the seat ring blank, and the inner tank bonding is completed, forming a ring-inner tank blank. The multi-joint robot 1 places the ring-inner tank blank on the trimming table 10. After that, the inner tank high-pressure forming machine can enter the next cycle for grouting, and operations such as manual trimming can be performed here.

[0032] After the outer shell forming machine 5 grouts to the set time, the multi-joint robot 1 automatically picks the corresponding profiling pallet 90 and the ring-inner tank blank to a fixed position for slurry coating. After the outer shell forming machine 5 finishes grouting, the mold opening oil cylinder of the outer shell forming machine 5 drives the upper mold to rise. The multi-joint robot 1 drives the ring-inner tank blank coated with slurry into the outer shell forming machine 5 after mold opening. The ring-inner tank blank contacts and presses against the outer shell blank for bonding, waits for the bonding delay, and then blowback for demolding is performed to complete the bonding of the toilet blank. The multi-joint robot 1 places the bonded toilet blank on the trimming table 10, and bottom processing can be performed here.

[0033] After the preliminary processing of the toilet blank is completed, the multi-joint robot 1 places the profiling pallet 90 and the toilet blank into the in-air blank storage rack 2. After the bonded toilet blank is stored in the blank storage rack 2 for five grouting cycles, it is taken out by the multi-joint robot 1 and placed on the ground conveyor line 7 for subsequent trimming operations. After trimming is completed, the toilet blank enters the turning machine 8 and is turned 180 degrees. Then, the blank enters the processing line 3 for further trimming operations. After processing is completed, the separated profiling pallet 90 is placed into the return pallet lifter 71. The return pallet lifter 71 sends the profiling pallet 90 into the lower return pallet conveyor chain 70. The profiling pallet 90 is conveyed to the starting end of the conveyor line 7 through the return pallet conveyor chain 70, facilitating the multi-joint robot 1 to pick up the profiling pallet 90. The return pallet lifter 71 returns to the starting height. At this time, the entire forming, bonding, and processing process is completely completed.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
