[0002] On the production line of new energy vehicles, the handling of new energy battery modules is a crucial and extremely demanding task. Traditional handling methods, whether manual or simple mechanized operations, are difficult to meet the stringent requirements of modern production lines for efficiency, precision and safety. The existing method for handling new energy battery modules uses a robot to drive a module gripper, and the module gripper uses multiple sets of suction cups to hold the battery workpiece or uses an air gripper to clamp the workpiece for handling. However, if the suction cup runs out of air and fails to hold the workpiece or the air gripper suddenly runs out of air during the handling process, the workpiece is easy to fall and damage the workpiece. In response to this, the existing technology has improved this problem by setting an anti-falling device on the module gripper, but the structure of most anti-falling devices is relatively complex, occupies a large space and is also costly.

[0023] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments. Example 1

[0024] like Figure 1-4As shown, this embodiment provides an anti-dropping device for a long-stroke swing arm. The anti-dropping device comprises: a cylinder mounting bracket 1, a cylinder 2, a guide sleeve 3 and an anti-dropping assembly 4; the cylinder 2 is mounted on the upper end of the cylinder mounting bracket 1, and the guide sleeve 3 is mounted on the lower end of the cylinder mounting bracket 1; the lower end of the guide sleeve 3 is connected to the anti-dropping assembly 4.

[0025] In this embodiment, a rotating shaft 5 is provided in the guide sleeve 3, the upper end of the rotating shaft 5 is connected to the cylinder 2, and the lower end is connected to the anti-drop assembly 4, wherein the cylinder 2 is connected to the upper end of the rotating shaft 3 through a cylinder joint 10. Specifically, one end of the cylinder joint 10 is connected to the bottom of the cylinder 2, and the other end is connected to the top of the rotating shaft 3; when receiving an action signal from the cylinder 2, the cylinder 2 extends upward, driving the rotating shaft 3 to descend along the guide shaft 2, and driving the anti-drop assembly 4 to descend at the same time.

[0026] In this embodiment, a roller guide 6 is provided on the rotating shaft 5, and the roller guide 6 is fixed to the rotating shaft 5 through a connecting rod 11. In addition, a slide groove 7 for the movement of the roller guide 6 is provided on the guide sleeve 3, and the roller guide 6 is fixed to the rotating shaft 3 through the slide groove 7. Specifically, the guide sleeve 3 is provided with a slide groove 7, such as Figure 5-6 As shown; the chute 7 is opened on one side of the guide sleeve 3, near the bottom of the guide sleeve, the opening direction of the chute 7 changes, and is bent toward the direction of the cylinder mounting frame 1, as shown Figure 1 As shown, a roller guide 6 is installed on the rotating shaft 5, and the roller guide 6 is fixed on the rotating shaft 5 through a connecting rod 11. The roller guide 6 passes through the guide sleeve 3 and moves along the fixed track of the open slide groove 7, driving the movement of the rotating shaft 5. When the roller guide 6 moves to the bending position of the slide groove 7, the roller guide 6 continues to move along the slide groove 7, and the rotating shaft 5 will start to rotate in the direction of the cylinder mounting frame 1.

[0027] In this embodiment, the anti-dropping assembly 4 includes an anti-dropping block 8 and a protective block 9; the anti-dropping block 8 is vertically fixed to the lower end of the rotating shaft 3 by bolts; the protective block 9 is fixed to the upper surface of the anti-dropping block 8 by bolts. Specifically, the anti-dropping assembly 4 includes an anti-dropping block 8 and a protective block 9, wherein the anti-dropping block 8 is vertically installed at the lower end of the rotating shaft 3 passing through the guide sleeve 2, and the installation direction of the anti-dropping block 8 is also perpendicular to the direction of the cylinder mounting frame 1 and is fixed by bolts, such as Figure 1As shown. The protection block 9 is fixed to the anti-drop block 8 by bolts. The protection block 9 is made of polyurethane. Since the material of the polyurethane block is relatively soft, it can directly contact the workpiece without damaging the surface of the workpiece, and can play a protective role in the process of transporting the workpiece. When the cylinder 2 is extended into place, the rotating shaft 3 drops to the lowest point, and the roller guide 4 drives the rotating shaft 3 to rotate, and finally drives the anti-drop block 8 and the protection block 9 to swing 90 degrees toward the cylinder mounting frame, so that the anti-drop component 4 is located below the workpiece, realizing the function of supporting the workpiece.

[0028] This embodiment provides an anti-dropping device for a long-stroke swing arm. The anti-dropping device provides power through the extension action of the cylinder, so that the roller guide moves along a predetermined trajectory to drive the rotating shaft in the guide sleeve and the anti-dropping component at the lower end of the rotating shaft to achieve the lifting and swinging functions, thereby achieving the function of supporting the workpiece, and the anti-dropping device has a simple and compact structure, is easy to use, meets the use requirements, and is easy to maintain.

[0029] The working principle of the utility model is: the anti-drop device of the long-stroke swing arm of the utility model is installed on the robot driving module gripper. After the installation is completed, the robot sends a signal, the cylinder 2 extends, drives the rotating shaft 5 to descend, and the roller guide 6 fixed on the rotating shaft 5 moves along the motion trajectory of the slide groove 7 provided by the guide sleeve 3. When the roller guide 6 moves to a certain position, the rotating shaft 5 begins to descend and rotate, driving the anti-drop component 4 installed at the lower end of the rotating shaft 5 to swing toward the cylinder mounting frame 1, that is, the workpiece position direction. When the cylinder 2 is fully extended, the rotating shaft 3 is lowered into place, and the anti-drop component 4 swings to the bottom of the workpiece to hold the workpiece. After the action is completed, the robot starts to carry the workpiece. In this way, even if the gas is suddenly cut off during the transportation process, the workpiece is not easy to fall and cause damage to the workpiece, and the safety of the operation is also guaranteed.

[0030] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
