The upper positioning groove and the lower positioning groove are both provided with openings in the direction of the slide 4. When the gasket 24 enters the upper positioning groove and is positioned, and the spring 25 enters the lower positioning groove and is positioned, the axis of the gasket 24, the axis of the spring 25 and the axis of the through hole 23 are collinear, and the diameter of the gasket 24 is larger than the diameter of the through hole 23.

[0032] A first sensor 26, a second sensor 27 and a third sensor 28 are provided on the outer wall of the slideway 4. 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.

[0033] 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.

[0034] The lifting slide 13 is provided with a sixth sensor 32 and a seventh sensor 33 . The sixth sensor 32 is used to detect whether the upper positioning slot is empty, and the seventh sensor 33 is used to detect whether the lower positioning slot is empty.

[0035] The assembly fixture 11 includes a support base 34 at the bottom, and a positioning assembly pin 35 is provided 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.

[0036] The two protruding parts on the baffle are respectively a gasket baffle 36 and a spring stopper 37. The distance 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 distance between the projections of the spring stoppers 37 on different cylinders on the central axis of the slide 4 is D2. The diameter of the spring 25 is D2.

[0037] 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:

[0038] Place multiple gaskets 24 into the gasket cavity at the upper part of the slide 4 in sequence, and place multiple springs 25 into the spring cavity at the lower part of the slide 4 in sequence. Since the slide 4 is tilted as a whole, the gaskets 24 and springs 25 will automatically slide to the lower end under the action of gravity.

[0039] When the gasket 24 and the spring 25 slide to the first cylinder 5 and the second cylinder 6, the two cylinders alternately operate under program control, thereby ensuring that only one workpiece (gasket 24 or spring 25) can slide out of the exit of the slideway 4 at a time. During the operation 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 monitor whether the working state is normal.

[0040] When the first sensor 26 and the second sensor 27 can both 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 the pair of gaskets 24 and springs 25 slide downward along the slide 4 and eventually enter the material receiving fixture in the assembly material receiving mechanism. 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 grooves, their central axes are in a coaxial state.

[0041] 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 pressure plate 15 to move. The two ends of the pressure 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 material 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.

[0042] During the upward movement of the assembly jig 11, its positioning assembly pin 35 is inserted into the spring 25 from below. When the step on the top of the support base 34 contacts the spring 25, it pushes the spring 25 upward. This displacement allows 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.

[0043] During the above process, when the gasket 24 and the spring 25 are connected as an integral structure, the third lower stop 20 on the top of the linkage frame 10 just contacts the third upper stop 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 17 on the top of the lifting slide 13 contacts the first upper stop 16 on the top of the slide rail 12. At this time, the lifting slide 13 and the assembled workpiece thereon (gasket 24 and spring 25) move together to the high position, which is the material removal position.

[0044] When the third sensor 28 detects the gasket 24, the control system controls the swing cylinder 14 to work, the pressure plate 15 is lifted, and the assembled workpiece regains its freedom. Then the control system sends a signal to the robot between the current station and the next station, and the robot moves to the assembled workpiece and removes it from the material receiving fixture.

[0045] When the third sensor 28 detects that the gasket 24 is removed, the control system first controls the lifting cylinder 9 to retract, the linkage frame 10 and the lifting slide 13 return to the initial position, the first cylinder 5 and the second cylinder 6 work, and a pair of gaskets 24 and springs 25 are released again. The device repeats the above actions to realize the sorting, assembly of the gaskets 24 and springs 25, and the operation of transporting the assembled workpiece to the standard material taking position, facilitating the material taking operation of the mechanical hand.
