DETAILED DESCRIPTION

[0024] See also Figure 1 The utility model provides a lateral flip positioning mechanism, including a flip translation assembly; the flip translation assembly includes a flip shaft 11, and a right-angle arm 1 is fixedly sleeved on the flip shaft 11; the right-angle arm 1 has two positioning claws with an angle of 90°;

[0025] The flip shaft 11 is rotatably connected to the translation slider 2; the translation slider 2 is also connected to the matching straight piece 22 and slidably connected to the limit rail 21; the translation slider 2 can perform reciprocating linear motion along the straight piece 22.

[0026] The right-angle arm 1 is also rotatably connected to the inclined tie rod 12; one end of the inclined tie rod 12 is rotatably connected to the fulcrum seat 13, and the other end is rotatably connected to the right-angle arm 1;

[0027] Combination Figure 2 Explain the positioning working principle of the utility model:

[0028] Figure 2 -a, the box 100 moves onto the right-angle arm 1;

[0029] Figure 2 -b, the translation slider 2 moves along the straight member 22, and pulls the flip axis 11 to translate; the inclined rod 12 rotates around the fulcrum seat 13, and pulls the right-angle arm 1 to rotate, so that the box 100 flips sideways with the right-angle arm 1. The box 100 tilts at a certain angle with the right-angle arm 1, and under the action of gravity, its side and bottom surfaces are respectively attached to the corresponding positioning claws of the right-angle arm 1.

[0030] As an application mode, at this time, the translation slider 2 can move in the reverse direction to return the right-angle arm 1 to its original position. Since the side of the box 100 fits the positioning claw of the right-angle arm 1, the positioning claw can be used as a reference to achieve the positioning of the box 100. After that, any box 100 can be accurately positioned through this action.

[0031] Figure 2-c, as an application mode, the translation slider 2 continues to translate until the right-angle arm 1 completes a 90° rotation. At this time, the box 100 is flipped 90° sideways. Since the box 100 also translates in the horizontal direction while flipping, the central axis of the box 100 can be translated to a predetermined position after completing a 90° side flip.

[0032] A skilled technician can set the translation distance of the right-angle arm 1 to complete a 90° flip according to the size of the box 100, and accurately control the translation distance of the central axis of the box 100 after it flips over. For example, after the box 100 flips over, the central axis is still located in the original vertical plane. Or, after the box 100 flips over, the central axis moves to the left or right a certain distance relative to the original vertical plane. In this way, the posture and position of the box 100 after flipping over can be accurately controlled, laying a foundation for the smooth execution of subsequent actions.

[0033] As an embodiment of the flip translation assembly, the straight member 22 is a lead screw and is threadedly connected to the translation slider 2; by controlling the rotation of the lead screw, the reciprocating motion of the translation slider 2 on the straight member 22 is controlled.

Optionally, the translation driving member of the utility model can be a horizontally arranged driving cylinder, which is connected to the translation slider 2, and the reciprocating motion of the translation slider 2 on the straight member 22 is controlled by controlling the extension and contraction of the driving cylinder. This embodiment can quickly realize the reciprocating motion of the translation slider 2, and the translation slider 2 has a strong load capacity, which is suitable for the side flip positioning operation of the box 100 with a large weight.

[0035] As an embodiment of the flip translation assembly, the straight member 22 slides through the translation slider 2; the straight member 22 is a cylinder body of a magnetic coupling rodless cylinder; the cylinder body is provided with a piston block for magnetic coupling with the translation slider 2; by passing gas into the cylinder body, the moving direction and moving distance of the piston block are controlled, and the reciprocating motion of the translation slider 2 on the straight member 22 is controlled. This embodiment has a compact structure, saves space, and the translation stroke of the translation slider 2 is long.

[0036] As a preferred solution, there are multiple right-angle arms 1, which are arranged at equal intervals on the flip axis 11, and they jointly support the box 100, and the force is evenly distributed. Optionally, the right-angle arm 1 of the utility model is in the shape of a thin plate to reduce the weight.

[0037] Preferably, there are two inclined rods 12, which are symmetrically arranged on both sides of the central axis of the straight member 22; when the translation slider 2 moves, the load on the flip shaft 11 is symmetrical to avoid twisting, jamming and the like.

[0038] As an embodiment, since the flipping and translational assembly must first complete the posture change of the box 100, the displacement in the horizontal direction after the side flipping is limited. Therefore, in order to be applicable to boxes 100 of various specifications, the position of the box 100 after flipping can be more accurately controlled. The lateral flipping positioning mechanism of the utility model also includes a compensating translational assembly; the compensating translational assembly is configured to: carry the flipping and translational assembly, and accurately adjust the displacement of the flipping and translational assembly in the horizontal direction; so that the central axis of the box 100 can be located at a predetermined position after flipping. Lay the foundation for the execution of subsequent conveying, arranging, stacking and other actions.

[0039] As an embodiment, the compensating translation assembly of the utility model includes a first translation plate 3 and a second translation plate 31 which can be moved horizontally synchronously; the straight member 22 and the limit rail 21 of the flipping translation assembly are fixed on the first translation plate 3, and the fulcrum seat 13 is fixed on the second translation plate 31; by controlling the horizontal translation amount of the first translation plate 3 and the second translation plate 31, the position of the box 100 after flipping is accurately controlled; optionally, the compensating translation assembly and the flipping translation assembly of the utility model can operate simultaneously, and during the lateral flipping of the box 100, the adjustment of the horizontal movement amount is completed synchronously to improve the operation efficiency.
