[0025] The application embodiment provides an automatic grabbing device for warm edge bar processing, effectively solves the technical problem that when processing, the warm edge bar is long in strip length, only a section can be grabbed when grabbing, and when longitudinally cutting and grooving, the cutting mechanism can only cut one point, so the warm edge bar needs to be moved, the existing grabbing device will change the grabbing position during the movement of the warm edge bar, and then the warm edge bar will lose support during the change, which is easy to cause the warm edge bar to be skewed, causes the cutting position to deviate, and reduces the processing quality, when the second step motor is rotated, the two clamping frames will slide inward at the same time to clamp the warm edge bar (the transmission belt contacts the warm edge bar), when longitudinally cutting, the first step motor will be started, the first step motor drives the transmission wheel to rotate, the transmission wheel will drive the transmission belt to rotate, and the transmission belt will drive the warm edge bar to slide, in this process, the mechanical arm remains stationary, and the application remains clamped to the warm edge bar, which can avoid the deviation of the cutting position, achieve the effect of improving the processing quality, and during installation, the positions of the two sliding plates can be slid transversely, the bolts at the two ends of the sliding plate are tightened after the sliding plate is slid to the required position, the bolts are tightened to abut against the mounting seat, the position of the sliding plate is fixed through friction, then the positions of the two positioning mounting blocks on the sliding plate are slid, so that the positioning mounting blocks can be aligned with the mounting threaded column on the mechanical arm, then the threaded column is inserted into the positioning mounting block, and the installation is completed through the fixing of the nut, and the effect that the device can be suitable for the installation of different specifications of mechanical arms is achieved. Embodiment

When performing longitudinal cutting and grooving, the cutting mechanism can only cut at one point, which requires moving the warm edge strip. However, in existing gripping devices, the gripping position changes during the movement of the warm edge strip. During this change, the warm edge strip loses support, which can easily cause it to become skewed, resulting in a shift in the cutting position and reducing the processing quality. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an automatic gripping device for processing warm edge strips, including a sliding frame 1, on which a threaded rod 2 with positive and negative threads is rotatably mounted, and at both ends of the threaded rod 2, a clamping frame 3 for clamping the warm edge strip is symmetrically threaded, and on the clamping frame 3, a transmission wheel 4 is rotatably mounted symmetrically, and a transmission belt 5 for driving the warm edge strip is installed between the two transmission wheels 4.
