Specifically, the robotic arm includes a plate 3, a second cylinder 4, and a movable arm 5. The second cylinder 4 is fixed to the plate 3, and the piston rod of the second cylinder 4 is fixedly connected to the movable arm 5. The movable arm 5 includes a first connecting section 501, a second connecting section 502, and a flipping section 503. One end of the second connecting section 502 is hinged to one end of the first connecting section 501, and the other end of the second connecting section 502 is hinged to the flipping section 503. The other end of the first connecting section 501 is fixedly connected to the piston rod of the second cylinder 4. The flipping section 503 is also hinged to the plate 3. In this embodiment, the plate 3 has a slot 301 in the middle, and the movable arm 5 is disposed in the slot 301. The first connecting section 501 is fixedly connected to the piston rod of the second cylinder 4 by a connector 507. The flip section 503 includes a first limiting part 504 and two second limiting parts 505. The two second limiting parts 505 are located on both sides of the first limiting part 504 and are fixedly connected to the first limiting part 504. The first limiting part 504 is hinged to the second connecting section 502 and is also hinged to the insert plate 3 via a fixed shaft 508. To further improve the stability of the flip section 503 in fixing the seat, the second limiting part 505 is provided with a protrusion 506, and the insert plate 3 is provided with a groove 302 that matches the protrusion 506. By setting the groove 302 to cooperate with the protrusion 506, the flip section 503 is limited and fixed, so that the flip section 503 can rotate within a certain range.

[0039] To ensure smoother movement of the robotic arm driven by the first cylinder 2 in the limiting assembly, the insert plate 3 is slidably connected to the main body 1. Specifically, two slide rails 6 are fixed on the inner side of the main body 1, arranged symmetrically. Each slide rail 6 has a slider 7, which can move back and forth on the slide rail 6. The insert plate 3 is fixedly connected to the first fixing member 8, and the first fixing member 8 is fixedly connected to the slider 7, so that the movement of the insert plate 3 drives the slider 7 to move back and forth on the slide rail 6. With this arrangement, the movement of the insert plate 3 is more stable.

[0040] The robot gripper device of this utility model also includes a first support assembly and a second support assembly. The first support assembly includes a third cylinder 10 and a first support member 11. The third cylinder 10 is fixed to the main body 1, and the piston rod of the third cylinder 10 is fixedly connected to the first support member 11.

In the second support assembly, the piston rod of the fourth cylinder 12 is arranged vertically. In this embodiment, there are two sets of second support assemblies, which are fixed on both sides of the main body 1 and arranged symmetrically. Through the cooperation of the first support assembly, the second support assembly, and the limiting assembly, the seat is positioned from three directions, making it more stable during the transfer of the seat.

[0041] The working process of the off-line robot gripper device of this utility model is as follows: When the car seat moves to the off-line robot gripper station on the production line, the first cylinder 2 is turned on, which pushes the insert plate 3 to move towards the car seat and pass through the gap between the seat back and the seat cushion. Then the second cylinder 4 is turned on, which drives the movable arm 5 to move. The flipping section 503 at the end of the movable arm 5 rotates, changing from a horizontal state to a vertical state, clamping and fixing the seat. Then the third cylinder 10 and the fourth cylinder 12 are turned on, which push the first support member 11 and the second support member 13 respectively to press them tightly against the seat back and the seat cushion. In cooperation with the flipping section 503, the car seat is fixed from three directions and removed from the production line.
