Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of new energy batteries, in particular to a contact-type anti-falling gripper mechanism. Background Art
[0002] Batteries are flammable and explosive products, so safety in the assembly process of new energy vehicle battery packs is particularly important. Especially in module assembly, how to prevent the module from falling when the gripper grabs and releases the module is the most important aspect in the entire assembly project.
[0003] However, some of the current gripper structures cannot directly contact the battery cells, resulting in the module falling and can only serve as a buffer, which may also cause flammable and explosive risks. When the suction cup gripper breaks and falls on the existing anti-fall mechanism, even if there is no safety hazard, the module cannot be easily removed or grabbed again on the anti-fall mechanism. In addition, direct contact with the battery cells will wear the battery cells and increase the risk of flammability and explosion. The suction cup gripper breaks and the module falls, causing the module to be scrapped, increasing production costs.
[0004] In summary, the existing technology has the following disadvantages in the battery pack production process:
[0005] 1. There is a risk of the module falling during the module grabbing and releasing process, which may cause explosion safety hazards;
[0006] 2. During the module picking and releasing process, the anti-fall mechanism cannot contact the battery cell, causing the battery cell to fall and scratch the structure, causing explosion safety hazards or other secondary injury safety risks;
[0007] 3. When the module is picked up and placed, after the suction cup gripper is disconnected, even if there is an existing anti-fall mechanism, it is difficult to take it out or grab it again due to its large size and heavy mass. Utility Model Content

[0030] The principle of the contact-type anti-falling gripper mechanism of the utility model is:
[0031] The gripper drive cylinder 2 can drive the gripper 3 to flip around the support shaft 12, so that the gripper 3 flips to a position where the product is inserted, and then the locking drive cylinder 4 drives the locking block 41 to lock the movement of the piston rod of the gripper drive cylinder 2, thereby preventing the gripper 3 from moving and playing a role in preventing it from falling.
[0032] In the above structure, the mounting bracket 1 is connected with two symmetrical and parallel right-angle plates 13, and the right-angle plates 13 are provided with a through hole 131 and a through hole 2 132, and the through hole 131 and the through hole 2 132 are connected, and the through hole 131 is used for guiding the movement of the drive shaft 11, and the through hole 2 132 is used for guiding the movement of the support shaft 12. A gap is provided between the two symmetrical and parallel right-angle plates 13, and one end of the gripper 3 is placed between the two symmetrical and parallel right-angle plates 13. The through hole 131 and the through hole 2 132 are arranged at right angles, and the ends of the through hole 131 and the through hole 2 132 that are far away from each other are both arranged as arc grooves, and the gripper driving cylinder 2 can drive the drive shaft 11 to move along the through hole 131 during the extension or retraction process of the piston rod, and the two ends of the support shaft 12 are respectively placed in the through hole 2 132 of the right-angle plate 13. In addition, both ends of the driving shaft 11 in the axial direction are connected to guide rollers 111, which are placed in through hole 131 and can move along through hole 131. Both ends of the supporting shaft 12 in the axial direction are connected to guide rollers 121, which are placed in through hole 132.
[0033] The specific structure for preventing falling in the above structure is that the piston rod of the gripper drive cylinder 2 is connected with an adapter 21, the drive shaft 11 is connected to the adapter 21, and the locking block 41 is used to lock the adapter 21. The end of the locking block 41 away from the locking drive cylinder 4 is provided with a locking groove 42, and the adapter 21 is placed in the locking groove 42 to achieve locking.
[0034] In the above structure, a rectangular block 5 is connected to the right-angle plate 13, a rectangular through hole 51 is provided on the rectangular block 5, the locking drive cylinder 4 is installed on the rectangular block 5, the locking block 41 is arranged in the rectangular through hole 51, and the rectangular through hole 51 is used for guiding the movement of the locking block 41.
