[0030] After the first brake disc is stacked, the first cylinder 5 is used to drive the mounting frame 7 to move upward, so that the turntable 9 enters the circular groove 2 on the left, so that the top of the turntable 9 is flush with the top of the gantry 1, and the external manipulator places the grabbed brake disc on the turntable 9. As the intermittent motor 8 runs, the turntable 9 is driven to rotate intermittently to place a single layer of multiple brake discs on the turntable 9; after the single layer placement is completed, the first cylinder 5 drives the turntable 9 to move downward, so that the top surface of the brake disc is flush with the top of the gantry 1, and the second cylinder 6 runs, and the push plate 12 moves upward to push a gasket 11 out of the circular groove 2 on the right, and then the pusher is used to push the gasket 11 into the circular groove 2 on the left, and then the pusher is reset, and then the external manipulator works to stack the second layer of brake discs, and repeats the above steps until the bottom end of the turntable 9 contacts the bottom end of the inner cavity of the container 4, thereby realizing multi-layer isolated stacking of the brake discs.

[0031] In an embodiment of the present utility model, by setting the No. 2 cylinder 6, the gasket tube 10, the gasket 11 and the push plate 12, after the single layer of the brake disc is placed, the No. 2 cylinder 6 is operated, and a gasket 11 is pushed out of the circular groove 2 on the right by the push plate 12, and the gasket 11 is pushed into the circular groove 2 on the left by the pusher. At this time, the gasket 11 is placed on the previously placed brake disc, which can avoid the impact friction of the upper and lower layers of brake discs during subsequent stacking and protect them; by setting the intermittent motor 8 and the turntable 9, as the intermittent motor 8 runs, the turntable 9 is driven to rotate intermittently, so that multiple brake discs in a single layer can be placed on the turntable 9.

In the initial state, the push bar 17 is located at the rightmost side of the slide rail 13 and is fixed between the two slide plates 14 by the push bar 17. When the servo motor 16 is started, the screw 15 and the slide plate 14 are threaded together to drive it to move, thereby driving the push bar 17 to move and pushing the gasket 11 to move.

[0034] Among them, the two sides of the two slides 14 close to each other are fixed with vertical plates 18 by bolts, and the two ends of the push strip 17 are respectively fixed on the sides of the two vertical plates 18, and the bottom end of the push strip 17 is flush with the top of the gantry 1. Bolt fixing facilitates the loading and unloading of the push strip 17.

[0035] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the container 4 includes vertical rods 19 and cross bars 20. Multiple cross bars 20 are arranged at equal intervals in the upper and lower directions. Multiple vertical rods 19 distributed in a circular array are fixedly connected between two adjacent cross bars. The vertical distance from the bottom end of the container 4 to the top end of the partition 3 is equal to the vertical distance from the bottom end of the mounting frame 7 to the bottom end of the turntable 9. A support member 21 is installed on the top end of the partition 3. The inner dimension of the support member 21 is equal to the outer dimension of the top surface of the mounting frame 7.

[0036] Rectangular slots 22 are defined at both the top of the mounting frame 7 and the bottom of the turntable 9. An electromagnet 23 is secured to the output end of the intermittent motor 8. The turntable 9 is made of iron. The electromagnet 23 slides through the rectangular slot 22 at the top of the mounting frame 7 and inserts into the rectangular slot 22 at the bottom of the turntable 9, forming a magnetic connection.

Bolts are inserted through the threaded holes 25 on the crossbar 20 and the threaded holes 25 on the turntable 9, securing the turntable 9 to the bottommost crossbar 20.

[0037] In the embodiment of the present invention, when stacking the brake discs, the No. 1 cylinder 5 is first used to drive the mounting frame 7 to move upward, so that the turntable 9 enters the circular groove 2 on the left, so that the top of the turntable 9 is flush with the top of the gantry 1, and the external manipulator places the grabbed brake disc on the turntable 9. As the intermittent motor 8 runs, the turntable 9 is driven to rotate intermittently to place multiple brake discs in a single layer on the turntable 9. After the single layer is placed, the No. 1 cylinder 5 drives the turntable 9 to move downward so that the top surface of the brake disc is flush with the top of the gantry 1. At this time, the No. 2 cylinder 6 runs, and a gasket 11 is pushed out to the right by moving the push plate 12 upward. The circular groove 2 on the side is then pushed and moved by a pushing member to the circular groove 2 on the left side, and then the pushing member is reset; then the external manipulator works to stack the second layer of brake discs, and the above steps are repeated until the bottom end of the turntable 9 contacts the cross bar 20 of the lowest layer. At this time, the threaded holes 25 on the turntable 9 and the cross bar 20 are connected by bolts, and then the power supply of the electromagnet moment block 23 is disconnected, and the No. 1 cylinder 5 drives the mounting frame 7 to move downward to separate it from the turntable 9. The operator directly removes the container 4 and the turntable 9 to remove the stacked brake discs, and then installs the new turntable 9 and container 4.

[0038] In the embodiment of the present utility model, by setting the vertical pole 19 and the cross bar 20, the brake discs stacked on it are limited and protected to prevent them from falling during the continuous downward movement of the turntable 9; by setting the rectangular groove 22, the electromagnetic moment block 23, the hidden groove 24 and the threaded hole 25, the turntable 9 and the threaded hole 25 on the cross bar 20 are connected by bolts, the power supply of the electromagnetic moment block 23 is disconnected, and the No. 1 cylinder 5 drives the mounting frame 7 to move downward into the hidden groove 24, thereby realizing its separation from the turntable 9, facilitating the removal of the container 4 and the turntable 9, and realizing the overall removal of the stacked brake discs.
