[0019] The outer wall of the slideway 4 is provided with a first sensor 26, a second sensor 27 and a third sensor 28. The first sensor 26 corresponds to the discharge position between the protruding parts on the two baffles in the gasket cavity, the second sensor 27 corresponds to the discharge position between the protruding parts on the two baffles in the spring cavity, and the third sensor 28 corresponds to the highest position of the gasket 24. The support plate 8 is provided with a sensor bracket 29, and the sensor bracket 29 is provided with a fourth sensor 30 and a fifth sensor 31 distributed longitudinally. The fourth sensor 30 and the fifth sensor 31 respectively detect the high position and the low position of the lifting slide 13.

The sixth sensor 32 is used to detect whether the upper positioning groove is empty, and the seventh sensor 33 is used to detect whether the lower positioning groove is empty.

[0020] The assembly fixture 11 includes a support base 34 at the bottom, and a positioning assembly pin 35 is arranged above the support base 34. The top of the positioning assembly pin is a conical head, and the connection between the support base 34 and the positioning assembly pin 35 is a limiting step.

[0021] The two protruding parts on the baffle are respectively a gasket baffle 36 and a spring stopper 37, the spacing between the projections of the gasket baffles 36 on different cylinders on the central axis of the slide 4 is D1, the diameter of the gasket 24 is D1, the spacing between the projections of the spring stoppers 37 on different cylinders on the central axis of the slide 4 is D2, and the diameter of the spring 25 is D2.

[0022] The working process of the gravity sliding device capable of realizing automatic assembly and loading of springs and gaskets according to the embodiment of the present invention is as follows: Multiple gaskets 24 are sequentially placed into the gasket cavity at the upper part of the slideway 4, and multiple springs 25 are sequentially placed into the spring cavity at the lower part of the slideway 4. Since the slideway 4 is tilted as a whole, the gaskets 24 and springs 25 will automatically slide to the lower end under the action of gravity. When the gasket 24 and the spring 25 slide to the first cylinder 5 and the second cylinder 6, the two cylinders act alternately under the control of the program, thereby ensuring that only one workpiece (gasket 24 or spring 25) can slide out from the exit of the slideway 4 each time. During the action of the two cylinders, the first sensor 26 detects whether the baffle on the second cylinder 6 blocks a gasket 24, and the second sensor 27 detects whether the baffle on the second cylinder 6 blocks a spring 25, so that the control system of the device can control whether the working state is normal; When the first sensor 26 and the second sensor 27 can detect the corresponding workpiece normally, the control system controls the second cylinder 6 to retract, the baffle controlled by the second cylinder 6 to retract, and a pair of gaskets 24 and springs 25 slide downward along the slideway 4, and finally enter the material receiving fixture in the assembly receiving mechanism respectively, specifically, the gasket 24 enters the upper fixed groove, and the spring 25 enters the lower positioning groove. After the two are positioned by the positioning groove, their central axes are in a coaxial state; When the sixth sensor 32 detects that there is a workpiece in the upper positioning groove, and the seventh sensor 33 detects that there is a workpiece in the lower positioning groove, the control system first controls the swing cylinder 14 to work, and the swing cylinder 14 drives the pressing plate 15 to move, and the two ends of the pressing plate 15 are respectively pressed against the top surfaces of the two gaskets 24; then the control system also controls the lifting cylinder 9 in the assembly receiving mechanism to work, and the lifting cylinder 9 drives the linkage frame 10 and the two assembly fixtures 11 thereon to move upward together. During the upward movement of the assembly jig 11, its positioning assembly pin 35 will be inserted into the spring 25 from below. When the step on the top of the support base 34 contacts the spring 25, the spring 25 will be pushed to move upward. This displacement will allow the top end of the spring 25 to pass through the through hole 23 opened on the material receiving partition 22 and connect with the gasket 24. In the above process, when the gasket 24 and the spring 25 are connected as an integral structure, the third lower stop block 20 on the top of the linkage frame 10 just contacts the third upper stop block 21 on the bottom end surface of the lifting slide 13. At this time, the linkage frame 10 pushes the lifting slide 13 to move upward together until the first lower stop block 17 on the top of the lifting slide 13 contacts the first upper stop block 16 on the top of the slide rail 12. At this time, the lifting slide 13 and the assembled workpiece (gasket 24 and spring 25) thereon move together to the high position, which is the material taking position. When the third sensor 28 detects the gasket 24, the control system controls the swing cylinder 14 to work, the pressing plate 15 is lifted, and the assembled workpiece recovers its degree of freedom. Then the control system sends a signal to the manipulator between the current station and the next station, and the manipulator moves to the assembled workpiece and takes it away from the material receiving fixture. When the third sensor 28 detects that the gasket 24 is taken away, the control system first controls the lifting cylinder 9 to recover, the linkage frame 10 and the lifting slide 13 return to the initial position, and the first cylinder 5 and the second cylinder 6 work to release a pair of gaskets 24 and springs 25 again. The device repeats the above actions to realize the sorting and assembly of the gaskets 24 and springs 25, and transport the assembled workpieces to the standard material picking position to facilitate the operation of the robot to pick up materials.
