As shown in fig. 1 to 6, the positioning and supporting mechanism for a mobile unit of the present embodiment, in which a plurality of universal wheels 21 are provided at the bottom of a mobile unit 2, includes:

the conveying mechanism 1, the conveying mechanism 1 can drive the mobile unit 2 to move. The transport mechanism 1 may comprise an AGV cart, i.e. an automated guided vehicle equipped with automatic guidance, so that the transport mechanism 1 can move the mobile unit 2 along a set path. Of course, in other alternative embodiments, the conveying mechanism 1 may also be adjusted according to actual needs. The transport mechanism 1 can be telescopic-connected to the moving unit 2 in the vertical direction so that the transport mechanism 1 can slide in the vertical direction relative to the moving unit 2 when the sleeve and the guide shaft located in the sleeve are relatively moved in the vertical direction. Of course, in other alternative embodiments, the conveying mechanism 1 may be connected to the moving unit 2 by a cylinder or other mechanism capable of sliding relative to the moving unit 2 in the vertical direction.

Of course, in other alternative embodiments, the fixing manner of the fixing unit 3 may be adjusted according to the need. The fixed unit 3 may include at least one guide portion 4 provided corresponding to the moving unit 2, and the guide portion 4 may be provided inside the fixed unit 3 so that the moving unit 2 can contact the guide portion 4 when the conveying mechanism 1 moves the moving unit 2 to the inside of the fixed unit 3. The guide portion 4 may include a slope portion 41 and a plane portion 42 connected to a rear side of the slope portion 41, a height of the slope portion 41 may be gradually increased from front to rear, and a height of the plane portion 42 may be the same as a height of the rear side of the slope portion 41, so that the moving unit 2 is in a suspended state when located at the plane portion 42.

In the embodiment, the conveying mechanism 1 includes an AGV cart, and the conveying mechanism 1 can drive the moving unit 2 to move along a predetermined route.

When the conveying mechanism 1 moves toward the direction of approaching the fixed unit 3, the conveying mechanism 1 brings the moving unit 2 close to the fixed unit 3. The moving unit 2 first contacts the front end of the inclined surface portion 41 and gradually contacts the rear end of the inclined surface portion 41, and the moving unit 2 contacts the flat surface portion 42 of the fixed unit 3 in the final state. The moving unit 2 is raised in the vertical direction so that the moving unit 2 is gradually in a suspended state. In the process, the conveying mechanism 1 is always in contact with the ground, thereby providing a force in the horizontal direction to the moving unit 2 so that the moving unit 2 can move toward the fixed unit 3. During the raising of the moving unit 2, the relative sliding of the moving unit 2 and the conveying mechanism 1 occurs in the vertical direction.

When the conveying mechanism 1 moves in a direction away from the fixed unit 3, the conveying mechanism 1 drives the moving unit 2 to move away from the fixed unit 3. The moving unit 2 is located at the flat portion 42 in the initial state, and gradually contacts the inclined surface portion 41 from the rear to the front during the movement, and does not contact the guide portion 4 in the final state. The moving unit 2 is lowered in the vertical direction so that the moving unit 2 is gradually changed from a suspended state to a state where the universal wheels 21 are in contact with the ground. In the process, the conveying mechanism 1 is always in contact with the ground, so that a force in the horizontal direction is provided to the moving unit 2, and the moving unit 2 can move in a direction away from the fixed unit 3. During the lowering of the moving unit 2, the moving unit 2 and the conveying mechanism 1 slide relatively in the vertical direction.

One side of the moving unit 2 may be provided with two rolling parts 22 on the same horizontal plane, and the other side of the moving unit 2 may be symmetrically provided with two rolling parts 22. In the present embodiment, the number of the rolling parts 22 is two, and the distance between the rolling parts 22 on both sides of the moving unit 2 may be the same as the distance between the guide parts 4, so that the rolling parts 22 can roll on the guide parts 4.

Specifically, as shown in fig. 1 to 6, the moving unit 2 may be provided with a positioning block 23, and the positioning block 23 may extend in the front-rear direction. The fixing unit 3 may be correspondingly provided with a stopper 5 capable of receiving the positioning block 23, so that when the moving unit 2 moves toward the fixing unit 3, the positioning block 23 may penetrate into the stopper 5, thereby fixing the moving unit 2.

In a preferred embodiment, as shown in fig. 1 to 6, the positioning block 23 is an isosceles triangle, the vertex angle of the positioning block 23 is set in the direction of the moving unit 2 in the horizontal direction, and the stopper portion 5 can abut against the positioning block 23. The position limiting portion 5 may include two rotation rollers for abutting against the positioning block 23, so that when the positioning block 23 moves toward the position limiting portion 5, the rotation rollers can abut against the triangular portion of the positioning block 23, so that the position limiting portion 5 gives the positioning block 23 a supporting force from the rear to the front, fixing the moving unit 2 from the rear to the front.

Specifically, as shown in fig. 1 to 6, the moving unit 2 may be provided with two positioning plates 24 on a plane perpendicular to the extending direction of the guide 4, the two positioning plates 24 may be respectively disposed on both sides of the moving unit 2, and the fixing unit 3 may be provided with two telescopic parts 6 capable of clamping the two positioning plates 24 rearward. So that the moving unit 2 can be fixed from the front to the rear by clamping the positioning plate 24 so that the fixing unit 3 can give a supporting force to the positioning block 23 from the front to the rear.

In a preferred embodiment, as shown in fig. 1 to 6, the telescopic portion 6 includes a telescopic cylinder 61 and a clamping portion 62 connected to the telescopic cylinder 61, and the clamping portion 62 can press and fix the positioning plate 24. Thereby fixing the moving unit 2 by the fixing action of the positioning plate 24.

In the present exemplary embodiment, the piston rod of the telescopic cylinder 61 is connected in rotation to the first connecting element 7.

When the telescopic cylinder 61 gradually extends out, the piston rod drives the first connecting piece 7 to move, and the first connecting piece 7 drives the second connecting piece 8 through one end connected with the second connecting piece 8. So that the ends of the first and

second links

7 and 8, which are not connected to each other, are rotated toward the moving unit 2. Accordingly, the end of the second connecting member 8 away from the first connecting member 7 drives the fixing portion 621 to press the rotating member backward, so that the rotating member moves backward and supports the positioning plate 24 backward, thereby achieving the effect of fixing the moving unit 2 backward by the fixing positioning plate 24.

When the telescopic cylinder 61 gradually contracts, the piston rod drives the first connecting piece 7 to move, and the first connecting piece 7 drives the second connecting piece 8 through one end connected with the second connecting piece 8. So that the ends of the first and

second links

7 and 8, which are not connected to each other, are rotated in a direction away from the moving unit 2. Accordingly, the end of the second connecting member 8 away from the first connecting member 7 drives the fixing portion 621 to pull the rotating member forward, so that the rotating member moves forward and away from the positioning plate 24, thereby eliminating the fixing effect on the positioning plate 24.

By means of the structure, the fixing effect of the positioning plate 24 and the fixing effect of the positioning plate 24 eliminated in the telescopic process of the telescopic cylinder 61 can be achieved. The positioning plate 24 can be fixed from the front to the rear, and the sliding when the mobile unit 2 is suspended can be prevented. Thereby achieving a fixation of the mobile unit 2.

The cross section of the end of the limiting member 10 adjacent to the positioning plate 24 may be a plane, so that the limiting member 10 can be completely attached to the side surface of the positioning plate 24 when the positioning plate 24 is fixed. Of course, in other alternative embodiments, the shape of the limiting member 10 can be adjusted according to actual needs.

As shown in fig. 1 to 6, the fixing method of the present invention includes the following steps:

the conveying mechanism 1 drives the moving unit 2 to move to the fixing unit 3 to the inclined plane part 41;

the conveying mechanism 1 drives the moving unit 2 to move backwards, so that the moving unit 2 moves on the inclined surface part 41 to the plane part 42, and in the process, the moving unit 2 moves upwards in the vertical direction relative to the conveying mechanism 1 to be separated from the ground.

By the method, the conveying mechanism 1 drives the mobile unit 2 to move from the position with lower height of the inclined plane to the position with higher height of the inclined plane, thereby realizing the effect of lifting the mobile unit 2. Then the moving unit 2 moves to the flat portion 42 and stops moving, thereby achieving an effect that the moving unit 2 is separated from the ground and maintains this state.

In a preferred embodiment, as shown in fig. 1 to 6, in the step "the conveying mechanism 1 drives the moving unit 2 to move backward so as to move the moving unit 2 on the inclined surface portion 41 to the plane portion 42, in the process, the moving unit 2 moves upward in the vertical direction relative to the conveying mechanism 1 so as to be separated from the ground", the positioning block 23 on the fixed unit 3 is pressed forward against the moving unit 2, and at the same time, the telescopic portion 6 is pressed backward against the moving unit 2.

Thereby preventing the moving unit 2 from falling from the fixed unit 3 to affect the blanking efficiency of the module. Thereby improving the efficiency of the mobile unit 2 in the module blanking process.
