DETAILED DESCRIPTION

The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

Example 1

As shown in Figure 1, this embodiment provides a folding mechanism 1, including a platform 11, the platform 11 includes an arc portion 111 and a plane portion 112, the arc portion 111 is inclined toward the plane portion 112; a guide mechanism 12 is arranged near the plane portion 112, the guide mechanism 12 includes at least two guide rods 13, the guide rod 13 includes a bending portion 131, and one end of the bending portion 131 close to the platform 11 extends in a direction close to the adjacent bending portion 131; the platform 11 is used for folding the short side box cover of the packaging box, and the bending portion 131 is used for folding the long side box cover of the packaging box.

The arc portion 111 may be arc-shaped in a portion connected to the planar portion 112 and the rest may be straight, or the arc portion 111 may be arc-shaped as a whole. This embodiment takes the arc portion 111 as an example in which a portion connected to the planar portion 112 is arc-shaped and the rest is straight.

The portion where the arc portion 111 is connected to the plane portion 112 has a certain curvature. One end of the arc portion 111 away from the plane portion 112 is located below the plane portion 112 and extends toward the plane portion 112. The angle at the connection between the arc portion and the plane portion is greater than 90 degrees.

The length of the plane portion 112 is relatively long, and the length of the arc portion 111 is relatively short. The mechanical arm or robot operates the platform 11, so that the arc portion 111 of the platform 11 abuts against the short side box cover of the packaging box. The short side box cover has a certain degree of softness, and the short side box cover is initially in a vertical state. The arc portion 111 drives the short side box cover to rotate inward, thereby folding the short side box cover. At this time, the short side box cover has a crease, but the folding angle of the short side box cover is less than 90 degrees.

The packaging box of this embodiment is a packaging box for placing an air conditioner indoor unit, and the packaging box is an empty box in the processing step. The arc portion 111 preliminarily folds the short side box covers on both sides of the packaging box, and after the two short side box covers have creases, the plane portion 112 presses down the preliminarily folded short side box covers. Since the plane portion 112 is relatively long and has a certain degree of flatness, the two short side box covers can be folded at one time using the plane portion 112, so that the folding angle of the two short side box covers is 90 degrees.

A guide mechanism 12 is provided near the plane portion 112, and the guide mechanism 12 includes a plurality of guide rods 13. In this embodiment, the guide mechanism 12 includes two guide rods 13. The bending portion 131 of one guide rod 13 is close to one end of the platform 11 and extends toward the bending portion 131 close to the other guide rod 13. The distance between the two guide rods 13 gradually decreases from the end closest to the platform 11 to the end farthest from the platform 11.

After the platform 11 folds the short side box cover of the packaging box, the mechanical arm or robot controls the guide rod 13 to contact the long side box cover of the packaging box. The long side box cover has a certain degree of softness, and the long side box cover is initially in a vertical state. The bending portion 131 of the guide rod 13 drives the long side box cover to rotate inward, thereby folding the long side box cover. The two long side box covers of the packaging box are creased, and the folding angle of the long side box cover is less than 90 degrees. The process of folding the long side box cover only needs to make the long side box cover crease, so as to soften the long side box cover, and the specific angle is not limited here.

The folding mechanism 1 provided in this embodiment includes a platform 11, the platform 11 includes an arcuate portion 111 and a plane portion 112, the arcuate portion 111 is inclined toward the plane portion 112; a guide mechanism 12 is provided near the plane portion 112, the guide mechanism 12 includes at least two guide rods 13, the guide rod 13 includes a bending portion 131, and one end of the bending portion 131 near the platform 11 extends toward the direction close to the adjacent bending portion 131; the platform 11 is used to fold the short side box cover of the packaging box, and the bending portion 131 is used to fold the long side box cover of the packaging box. The arcuate portion 111 is inclined toward the plane portion 112 and has a certain curvature. The arcuate portion 111 can drive the short side box cover to rotate toward the direction close to the plane portion 112, thereby folding the short side box cover. After the arc portion 111 folds the short side box cover, the folding angle of the short side box cover is less than 90 degrees. Then the flat portion 112 is used to press down the short side box cover after the initial folding, so that the folding angle of the short side box cover is 90 degrees. The bending portion 131 of the guide rod 13 extends toward the direction close to the adjacent bending portion 131 at one end close to the platform 11. The bending portion 131 is inclined. The bending portion 131 supports the long side box cover of the packaging box and folds the long side box cover inward. The above-mentioned folding mechanism 1 can fold the short side box cover and the long side box cover of the packaging box, so as to facilitate the automatic flipping of the packaging box in the subsequent process.

In the process of installing the packaging box of the traditional air conditioner indoor unit, the transfer and placement of the packaging box requires manual participation, the operation is cumbersome, and the risk is high. After installing the packaging box using the packaging box installation device of this embodiment, 450 packaging boxes of the air conditioner indoor unit can be installed per hour, while the previous manual operation can only install 250. Therefore, the packaging box installation device of this embodiment can increase the output by at least 50%, thereby shortening the production cycle.

In addition, the packaging box installation device of this embodiment only needs to operate the control mechanism to complete the automatic operation, and does not require complicated manual operation. Therefore, the operation is simple and easy to learn, and the personnel skill requirements are low. At the same time, the device has high safety and eliminates the safety hazards caused by manual operation.

The packaging box installation device of this embodiment also includes an unpacking mechanism 4, which includes an unpacking frame 41, and the unpacking frame 41 is provided with a suction cup 5; a rotating shaft 42 is installed on the side of the unpacking frame 41, and the rotating shaft 42 is connected to an unpacking plate 43, and the unpacking plate 43 is connected to the suction cup 5. The unpacking mechanism 4 also includes a push-rotating cylinder 44, and both ends of the push-rotating cylinder 44 are connected to an articulated seat 45, and the articulated seat 45 close to the unpacking plate 43 is connected to the unpacking plate 43. The function of the unpacking mechanism 4 is to take out the air conditioner indoor unit packaging box from the material taking position, and then unfold the two-dimensional flat packaging box to a three-dimensional structure. A tooling vehicle with packaging boxes will be placed next to the robot, and the robot controls the unpacking mechanism 4 to take materials from the tooling vehicle. The two vacuum suction cups 5 on the unpacking plate 43 are used to stabilize the three-dimensional shape of the packaging box.
