[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A sanitary ware fitting assembly machine includes a machine base panel. A plastic part conveyor belt is provided on the machine base panel. A plastic part feeding device, a rubber ring feeding and assembling integrated device, and a shifting device are sequentially arranged on the machine base panel along the plastic part conveyor belt. The rubber ring feeding and assembling integrated device is located between the plastic part feeding device and the shifting device. A nut platform is provided on the machine base panel. A nut feeding device and a screw feeding and assembling integrated device are respectively provided on both sides of the nut platform on the machine base panel. A aligning device and a blanking track are also provided on the machine base panel. The aligning device is located between the shifting device and the screw feeding and assembling integrated device. The blanking track is located below the aligning device.

[0008] During assembly, the plastic parts loading device automatically grabs the plastic parts and places them on the plastic parts conveyor belt (with the plastic parts facing up). The plastic parts are transported by the plastic parts conveyor belt. The rubber ring loading and assembly device automatically grabs the rubber ring and places it on the transported plastic parts for automatic assembly. The shifting device then automatically grabs the assembled plastic parts and places them on the orientation device for orientation adjustment (rotation 180°). While the plastic parts and rubber rings are being assembled, the nut loading device automatically transports the nuts to the nut table. The screw feeding and assembly device automatically grabs the screws and places them on the nut table for automatic assembly. The assembled screws are then automatically shifted to the orientation device for final automatic assembly with the adjusted plastic parts, completing the assembly of bathroom accessories.

One end of the synchronous push rod is mounted on the side wall of the placement groove and is slidably connected thereto, and the other end of the synchronous push rod is fixed with a positioning clamp block 1. The plastic part is placed in the placement groove (the plastic part body is placed upward), and the plastic part is supported from all sides by the plurality of synchronous push rods (positioning clamp block 1), thereby improving the fixing effect of the plastic part in the placement groove, improving the stability of the plastic part when assembled with the rubber ring, and improving the product quality of the bathroom accessories.

[0010] Preferably, an annular cavity is provided inside the clamping table. The annular cavity is located outside the placement groove. A piston groove matching the synchronous ejector rod is provided on the inner wall of the annular cavity. A ejector rod through-hole is provided between the bottom surface of the piston groove and the side wall of the placement groove. The synchronous ejector rod is placed in the ejector rod through-hole and is slidably connected thereto. A piston is slidably connected in the piston groove. One end of the synchronous ejector rod is fixed to the piston. The piston and the bottom surface of the piston groove are connected by a first return spring. An oil inlet matching the piston groove is provided on the side wall of the annular cavity. The piston groove is located on the side of the oil inlet. A fuel distribution tank is provided on the fixed base. The oil inlet and the fuel distribution tank are connected by a oil pipe. By supplying oil to all the oil inlets simultaneously through the fuel distribution tank, the pressure oil can evenly fill the annular cavity, thereby driving the pistons in each piston groove to simultaneously push the synchronous ejector rods, enabling all the synchronous ejector rods (positioning clamp blocks one) to simultaneously hold the plastic part from all around, greatly improving the positioning accuracy of the plastic part in the placement groove, enhancing the assembly accuracy when the plastic part is assembled with the rubber ring, improving the product quality of the sanitary ware accessories, with high automation degree, convenient control, and good work continuity. The first return spring plays an automatic reset role for the piston and the synchronous ejector rod.

[0011] Preferably, the rubber ring feeding and assembling integrated device includes a bracket fixed on the machine base panel. A sliding seat is slidably connected to the bracket. The sliding seat is provided with a first rubber ring clamp and a second rubber ring clamp. An expanding ring device is provided on the machine base panel and below the sliding seat. The expanding ring device is used to automatically expand the inner diameter of the rubber ring, thus facilitating the mutual assembly with the plastic part. The first rubber ring clamp is used to automatically clamp the rubber ring onto the expanding ring device for ring expansion. The second rubber ring clamp is used to automatically clamp the rubber ring with an expanded inner diameter onto the transferred plastic part and automatically fit it outside the plastic part (the annular groove on the chassis). It has a high automation degree, convenient control, and good work continuity.

[0012] Preferably, a cylinder 1 is provided on the side of the sliding seat facing the machine base panel, and the rubber ring clamp 1 includes a clamp box body, and a plurality of slide grooves are provided on the inner bottom surface of the clamp box body, and the slide grooves are distributed in a ring shape about the central symmetry line of the clamp box body, and one end of the slide groove faces the center position of the inner bottom surface of the clamp box body, and the other end of the slide groove faces the edge of the clamp box body. A synchronous slider is slidably connected in the slide groove, and a clamping rod is fixed on the synchronous slider, and the clamping rod is placed outside the clamp box body and located below the clamp box body. A cylinder 2 is fixed above the clamp box body, and the cylinder 2 is fixed on the movable part of cylinder 1 On the plug rod, the second cylinder is provided with a second cylinder piston rod. A piston rod guide tube matching the second cylinder piston rod is provided at the center of the inner bottom surface of the clamp housing. The second cylinder piston rod extends through the top surface of the clamp housing and is positioned within the piston rod guide tube. The second cylinder piston rod and the clamp housing are slidably connected. A transmission rod 1 is provided between the second cylinder piston rod and the synchronous slider. One end of the transmission rod 1 is mounted on and hingedly connected to the synchronous slider, and the other end of the transmission rod 1 is mounted on and hingedly connected to the side wall of the second cylinder piston rod. The synchronous slider and the inner side wall of the clamp housing are connected via a second return spring. When the rubber ring clamp 1 is clamped, the clamping rod automatically shifts to a position inside the rubber ring. The second cylinder then automatically controls the second cylinder piston rod to move downward. Through the transmission action of the transmission rod 1, all the synchronous sliders (clamping rods) move simultaneously toward the inner wall of the rubber ring and support the rubber ring from the inside, thereby smoothly clamping the rubber ring. This system has a high degree of automation, convenient control, and good operational continuity. The second return spring plays the role of automatic return of the slider (clamping rod).

[0013] Preferably, the ring expanding device comprises a base plate fixed to the machine base panel, a placement rack and a ring expanding bag disposed on the base plate. The opening of the ring expanding bag is fixed to the base plate and sealed therewith. The placement rack is positioned inside the ring expanding bag, and the placement rack has a cross-sectional width that gradually increases from top to bottom. The machine base panel is provided with a blower, which is provided with an air duct that passes through the floor and is positioned inside the ring expanding bag. A clamping rod grasps the rubber ring and moves it above the ring expanding bag (directly above the placement rack). The piston rod of the second cylinder then automatically returns to its original position, and the slider (clamping rod) also automatically returns to its original position under the action of the second return spring, releasing the rubber ring. The rubber ring then automatically falls under the action of gravity and fits around the outside of the ring expanding bag (placement rack). The blower then blows air into the ring expanding bag through the air duct, causing it to expand and expand the rubber ring encased therein, thereby automatically expanding the inner diameter of the rubber ring. This facilitates assembly with the plastic component, resulting in a high degree of automation, easy control, and good operational continuity.

[0014] Preferably, a third cylinder is provided on one side of the sliding seat facing the machine base panel. The second rubber ring clamp includes a clamp cylinder body fixed on the piston rod of the third cylinder. The opening of the clamp cylinder body faces the machine base panel.

A fourth cylinder is fixed on the inner bottom surface of the clamp cylinder body. The inner cylinder is fixed on the piston rod of the fourth cylinder. An annular inner retaining edge is fixed at the opening of the clamp cylinder body.

[0015] When the second rubber ring clamp clamps, the clamp cylinder body automatically moves to the upper position of the rubber ring. Then, the third cylinder automatically controls the clamp cylinder body to move downward. At this time, the rubber ring passes through the annular inner retaining edge and enters the inside of the clamp cylinder body. The annular flange on the rubber ring is also made of rubber material. When the annular flange is blocked by the annular inner retaining edge, it can bend, so as to smoothly enter the inside of the clamp cylinder body along with the rubber ring. Then, the fourth cylinder automatically controls the inner cylinder to move downward, pressing the annular flange on the rubber ring against the annular inner retaining edge, thereby fixing the rubber ring after the inner diameter is enlarged. Then, it is clamped to the outside of the plastic part (the annular groove on the chassis) transmitted, and finally the rubber ring is released, enabling it to automatically tighten on the outside of the plastic part (the annular groove on the chassis). It has a high degree of automation, convenient control, and good work continuity.

[0016] Preferably, the orientation adjustment device includes a frame fixed on the machine base panel. The frame is placed above the blanking track.

A moving plate cylinder for controlling the synchronous moving plates is provided on the frame. A clamp motor for controlling the rotation of the positioning clamp blocks II is provided on the synchronous moving plates. The displacement device automatically grabs the assembled plastic part transmitted and places it between the two synchronous moving plates (positioning clamp blocks II). Then, the moving plate cylinder automatically controls the two synchronous moving plates to move towards the plastic part, so that the two positioning clamp blocks II on it clamp and fix the plastic part. Then, the two positioning clamps are simultaneously rotated 180° by rotating the clamp motor, so as to adjust the orientation of the plastic part.

Two synchronously moving plates are both provided with a second transmission rod. One end of the second transmission rod is hinged to the synchronously moving plate, and the other ends of the two second transmission rods are respectively hinged to both ends of the rotating rod. Through the cooperation of the rotating rod and the second transmission rod, on the one hand, it guides the movement of the two synchronously moving plates, and on the other hand, it enables the two synchronously moving plates to move towards the plastic part simultaneously, greatly improving the position accuracy after the plastic part is clamped, improving the assembly accuracy when the plastic part is assembled with the screw, enhancing the product quality of the sanitary ware accessories, with high automation, convenient control and good working continuity.

[0018] Preferably, the nut feeding device includes a nut transmission track. The nut table is placed on the side of the nut transmission track. The nut table is provided with a nut card slot.

The screw feeding and assembling integrated device includes a three-axis manipulator module. The three-axis manipulator module is provided with a screw gripper for gripping the screw and a rotating motor for controlling the rotation of the screw gripper. When assembling the screw and the nut, the nut is conveyed along the nut transmission track to the discharge end and automatically slides into the nut card slot through the side opening and is clamped. The three-axis manipulator module controls the screw gripper to grab the screw on the screw transmission track, displaces it above the nut, and screws the screw into the nut through the cooperation of the rotating motor. The nut card slot can clamp the nut when the screw is screwed in, and the screw avoidance hole can enable the screw to pass through smoothly. After the screw and the nut are assembled, it is then displaced above the plastic body after being adjusted in direction through the three-axis manipulator module, and the screw is screwed into the plastic body again through the cooperation of the rotating motor to complete the assembly of the sanitary ware accessories. It has high automation, convenient control and good working continuity, greatly improving the assembly efficiency and enhancing the product quality of the sanitary ware accessories.

[0051] On the one hand, the plastic parts feeding device 13 automatically grabs the plastic parts 4 and places them in the placement groove 34 (the plastic parts body 6 is placed upwards), and supplies oil to all the oil inlets 36 at the same time through the oil distribution tank 30, so that the pressure oil evenly fills the annular cavity 33, which can drive the piston 37 in each piston groove 35 to push the synchronous push rod 40 at the same time, so that all the synchronous push rods 40 (positioning clamp 1 41) can simultaneously support the plastic parts 4 from all sides to fix them, so that the plastic parts 4 can be stably transported under the action of the plastic parts conveyor belt 11; and the clamping rod 56 automatically shifts to the inner position of the rubber ring 3, and then the cylinder 2 54 automatically controls the piston rod of the cylinder 2 57 moves downward, and through the transmission action of the transmission rod 1 58, all the synchronous sliders 62 (clamping rods 56) are driven to move toward the inner wall of the rubber ring 3 at the same time and hold the rubber ring 3 from the inside, thereby smoothly clamping the rubber ring 3 and shifting it to the top of the expansion bag 49 (just above the placement rack 50). After that, the second piston rod 57 of the cylinder automatically resets, and the synchronous slider 62 (clamping rod 56) also automatically resets under the action of the reset spring 2 60, loosening the rubber ring 3. At this time, the rubber ring 3 automatically falls under the action of gravity and fits the outside of the expansion bag 49 (placement rack 50). Then the blower 53 presses the expansion bag 49 through the air guide pipe 52. Air is blown to expand the expansion bag 49, which stretches the rubber ring 3 on the outside, and then the clamp cylinder 63 automatically shifts to the upper position of the rubber ring 3. Then the cylinder three 48 automatically controls the clamp cylinder 63 to move downward. At this time, the rubber ring 3 passes through the annular inner rib 66 and enters the inside of the clamp cylinder 63. The annular flange 7 on the rubber ring 3 is also made of rubber material. When the annular flange 7 is blocked by the annular inner rib 66, it can bend, so that it can smoothly enter the inside of the clamp cylinder 63 with the rubber ring 3. Then the cylinder four 64 automatically controls the inner cylinder 65 to move downward, pressing the annular flange 7 on the rubber ring 3 onto the annular inner rib 66, thereby fixing the inner diameter The enlarged rubber ring 3 is then clamped to the outside of the transferred plastic part 4 (the annular groove 8 on the chassis 9) and the rubber ring 3 is released, so that it is automatically tightened on the outside of the plastic part 4 (the annular groove 8 on the chassis 9); the shifting device 17 automatically grabs the transferred assembled plastic part and places it between the two synchronous moving plates 68 (positioning clamp 2 69), and then the two synchronous moving plates 68 are automatically controlled by the moving plate cylinder to move toward the plastic part at the same time, so that the two positioning clamps 2 69 on them clamp the plastic part and fix it, and then the two positioning clamps 2 69 are controlled by the clamp motor to rotate 180° at the same time to adjust the direction of the plastic part.

[0052] On the other hand, the nut 2 is conveyed to the nut table 21 by the nut feeding device and automatically slides into the nut slot 75 through the side opening 73 and is clamped; the three-axis manipulator module (the screw feeding and assembling integrated device 22) controls the screw gripper to grab the screw 1 and shift it above the nut 2, and then screws the screw 1 into the nut 2 through the cooperation of the rotating motor (the nut slot 75 can clamp the nut 2 when the screw 1 is screwed in, and the screw avoidance hole 75 facilitates the smooth passing of the screw 1). After the screw 1 and the nut 2 are assembled, it is then shifted above the adjusted plastic body by the screw feeding and assembling integrated device 22, and the screw is screwed into the plastic body again through the cooperation of the rotating motor to complete the assembly of the sanitary ware fitting.
