[0029] In order to better understand the technical solution of the present application, the present application is described in detail below with reference to the accompanying drawings.

[0030] like Figure 2-8 As shown, the present application discloses a plate clamping device, including a connecting member 1 and a fixed plate 3, the connecting member is used to connect with the robot arm, and is fixedly arranged on the vertical side of the fixed plate 3, and multiple gripping mechanisms 4 with the same structure are arranged on the other vertical side of the fixed plate 3, the gripping mechanism 4 includes a slide rail 401 fixedly arranged on the fixed plate, a first mounting seat 403 and a second mounting seat 404 are slidingly arranged on the slide rail 401, and a clamping plate 405 is fixedly arranged on the side of the first mounting seat 403 and the second mounting seat 404 away from the slide rail, the clamping plate 405 on the first mounting seat 403 and the clamping plate 405 on the second mounting seat 404 are arranged opposite to each other, and a driving element 407 drives the first mounting seat 403 and the second mounting seat 404 to slide on the slide rail 401 to clamp the plate 04, and the first mounting seat 403 and the second mounting seat 404 have the same moving distance on the slide rail 401.

[0031] like Figure 2 , 4 As shown, the connecting member 1 is arranged on the central axis of the fixing plate 3, and the three gripping mechanisms 4 are evenly distributed along the length of the fixing plate 3, so that the plate clamping device is evenly stressed when clamping a long plate. In order to enhance the strength and rigidity of the fixing plate 3, reinforcing ribs 2 are fixedly arranged at the upper and lower ends of the fixing plate 3. Figure 3 As shown, the first mounting seat 403 and the second mounting seat 404 are both fixedly provided with a slider 402, and the slider 402 can slide on the slide rail 401, so that the first mounting seat 403 and the second mounting seat 404 can slide stably.
