A lifting cylinder and a servo motor are provided at the bottom of the table body. The output end of the lifting cylinder is connected to a spline shaft through a bearing. The servo motor is connected to drive the spline shaft to rotate through a synchronous belt and a synchronous pulley. The spline shaft passes through a guide sleeve fixed on the upper plate. The top of the spline shaft is connected to a wedge-shaped driving member. The connecting block connected to the segment-taking fork plate is slidably connected to the wedge-shaped driving member. The segment-taking fork plate is located at the top of the rotating disk. One end of the segment-taking fork plate is provided with a segment-taking notch. The connecting block is movably arranged in the notch of the rotating disk. The rotating disk is rotatably connected to the rotating disk frame. The beneficial effect of the present invention is that when the nut moves along the material channel to the rotating disk frame, the segment-taking fork plate extends, so that the nut enters the segment-taking notch at a fixed angle and stops on the material storage port of the rotating disk. The parking angle of the nut is consistent with the angle of the manipulator material taking hole, thereby improving the success rate of nut taking and the efficiency of nut installation.

Description

Technical Field

[0001] The invention relates to a material distributing device for mounting nuts on automobile tires, belonging to the technical field of material distributing devices. Background Art

[0002] When the robot installs the tire, it is necessary to first take the nut and then move it to a fixed installation position on the tire for installation. A material picking and installation sleeve is installed on the manipulator, and an electromagnet is provided in the inner hole of the sleeve. The shape of the sleeve matches the polygonal shape of the nut. When the sleeve approaches the nut to be taken for suction, the placement angle of the nut to be taken needs to match the angle of the inner hole of the sleeve on the manipulator before it can be sucked into the inner hole of the sleeve by the electromagnet to complete the material picking. However, the angle and posture of the nut after it is discharged from the vibration plate to the dividing plate through direct vibration are random. The polygonal material picking hole and the polygonal nut do not match, resulting in the nut being unable to enter the inner hole of the sleeve, affecting the success rate of the manipulator in taking the nut and the efficiency of nut installation. Summary of the invention

The upper plate 8 is connected to a bottom plate 11 on the table body 1 through a pillar a10. The turntable frame 16 is fixed to the upper plate 8 through a pillar b17. A cover plate 18 connected to the spline shaft 5 is provided on the top of the wedge-shaped driving member 12.

[0027] The wedge-shaped driving member 12 includes a connecting hole 12.1 for connecting the spline shaft 5, a plurality of connecting plates 12.2 are evenly distributed around the connecting hole 12.1, an inclined slide rail 12.3 is provided at the end of the connecting plate 12.2, and a guide slot 12.4 is provided at the connection between the slide rail 12.3 and the connecting plate 12.2.

A guide bar is provided on the inner wall of the notch of the rotating disk 15, and the guide slot 13.2 is slidably connected to the guide bar. A feed port is provided on the rotating disk frame 16, and the feed port is connected to the discharge port of the material channel 19 of the vibrating feeding device.

[0028] The working principle of the present invention is as follows:

[0029] The wheel hub of the automobile tire is provided with several nut holes for installing nuts. The manipulator performs one-time installation through a corresponding number of material-picking and installation sleeves. The nut needs to be taken out before installation. According to the position and number of material-picking and installation sleeves installed on the manipulator, several storage ports for placing nuts are correspondingly provided on the circumference of the rotating disk 15. After a nut is placed in each storage port, the manipulator performs one-time grabbing through the material-picking and installation sleeve. Before grabbing, it is necessary to ensure that the angle of the outer polygon of the nut matches the angle of the inner hole of the material-picking and installation sleeve, so that the nut can smoothly enter the inner hole of the material-picking and installation sleeve. The process of the nut entering the storage port at a predetermined angle is as follows:

[0030] The servo motor 3 drives the spline shaft 5 to rotate through the synchronous pulley 7, and the spline shaft 5 drives the rotating disk 15 to rotate, so that the vacant material storage port of the rotating disk 15 is directly opposite to the material channel 19 outlet of the feeding device, and the lifting cylinder 2 drives the spline shaft 5 to move vertically upward (such as Fig.11 As shown in the figure, the spline shaft 5 drives the wedge-shaped driving member 12 to move upward, and the wedge-shaped driving member 12 interacts with the connecting block during the upward movement, so that the slide rail 12.3 and the guide groove 13.2 produce relative movement. Since the guide bar of the selection plate 15 is in the slide groove 13.1 of the connecting block 13, the connecting block 13 can only move laterally toward the feed port along the guide bar through the slide groove 13.1. The connecting block 13 simultaneously drives the segment fork plate 14 to move toward the feed port until the segment notch of the segment fork plate 14 moves to just above the storage port of the rotating disk 15, and the nut moves along the discharge port of the material channel 19 of the vibrating feeding device to the segment notch of the segment fork plate 14. The shape of the segment notch matches the shape of the nut, and the front end nut is under the thrust of the rear nut and the vibration of the material channel. Down, it rotates to an angle that coincides with the segment-taking notch, and enters the segment-taking notch, so that the nut is stored in the storage port of the rotating disk 15 at a predetermined angle to adapt to the inner hole of the sleeve on the manipulator to take the material; the rotating disk 15 rotates to make the next vacant storage port face the material channel 19, and the nut continues to be loaded. Until all the storage ports of the rotating disk 15 are filled with screws, the lifting cylinder 2 drives the wedge-shaped driving member 12 to move downward, and the guide slide groove 12.4 acts on the groove edge 13.3 to push the groove edge 13.3 obliquely downward, so that the connecting block 13 drives the segment-taking fork plate 14 to separate from the nut, and the manipulator drives the material-taking installation sleeve to move to the top of the nut, and then approaches it to suck the nut into the inner hole of the sleeve, and then moves to the nut installation position on the hub, and the material-taking installation sleeve rotates to install the nut in place.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
