For the arrangement of the oblique movable needling gripping fixture, the cooperation of the pushing motor 52 and the swinging motor 53 drives the oblique movable plate 5 to move and swing in the oblique direction between the transverse direction and the longitudinal direction, so that the positions of the gripping needles corresponding to the four corners of the sponge are adjusted, and the adjustment is more convenient.

In the present invention, the obliquely movable needling gripping jig mounted on the gripping frame 1 may be replaced by a bidirectionally movable needling gripping jig, as shown in fig. 13.

In the invention, the matching between the moving plate and the driving motor is realized by adopting the matching of the lead screw and the lead screw nut, so that the moving distance of the moving plate can be accurately adjusted, and in addition, the matching between the guide rail and the guide slide block is adopted, so that the moving path of the moving plate is guided and limited, and the phenomenon of deviation of the moving plate is avoided.

In this embodiment, each driving motor is a stepping motor, and the stepping motor can better control an angle of rotation of the motor and can move a relative distance according to requirements.

When the size of the sponge to be grabbed changes, the corresponding bidirectional moving plate driving motor 21, the longitudinal moving plate driving motor 31, the transverse moving plate driving motor 41 and the pushing motor 52 start to work to drive the corresponding lead screw to rotate, when the lead screw rotates, as the lead screw nut and the slider are fixed together, the lead screw nut can change from rotary motion to horizontal motion, so as to drive the bidirectional moving plates 2 to reciprocate in the transverse direction, the longitudinal moving plate 3 to reciprocate in the longitudinal direction, the transverse moving plate 4 to reciprocate in the transverse direction and the oblique moving plate 5 to reciprocate in the oblique direction, when the bidirectional moving plates 2 move transversely, the longitudinal moving guide 25 on the bidirectional moving plates 2 can also passively move along the transverse moving guide 26 under the moving action of the bidirectional moving plates 2, when the bidirectional moving plates 2 move in place, the longitudinal driving motor 29 works to drive the fixed seat 28 to reciprocate in the longitudinal direction, so that the bidirectional moving plate 2 moves in the transverse direction and the longitudinal direction, namely, the grabbing needles on the bidirectional moving plate 2 move in the oblique direction between the transverse direction and the longitudinal direction, after the oblique moving plate 5 moves in place in the oblique direction, the swing motor 53 drives the oblique moving plate 5 to swing, and finally, all the grabbing needles shrink towards the center of the grabbing bracket 1 or spread towards the outer side of the grabbing bracket 1, so that sponges of different sizes and different specifications are matched, all the grabbing needles can be uniformly distributed on the surface of the sponge, and the sponge can be conveniently grabbed.

The working principle is as follows: firstly, the produced sponge is conveyed to a deviation rectifying station through a conveying mechanism, the sponge is rectified through a deviation rectifying roller, the rectified sponge is conveyed to a sponge rolling machine 72, a layer of glue is coated on the upper surface of the sponge through the sponge rolling machine 72 to form a main sponge, the main sponge is continuously conveyed to the position below a visual camera A302, the position of the main sponge is detected through the visual camera A302, meanwhile, an auxiliary sponge is conveyed to the position below a visual camera B301 through an auxiliary sponge conveying machine 82, the position of the auxiliary sponge is detected through the visual camera B301, the main sponge and the auxiliary sponge are detected by the visual camera A302 and the visual camera B301, the computer controls the robot to move the sponge grabbing mechanism, the auxiliary sponge is compounded on the main sponge, the whole compounded sponge is conveyed to a sponge compounding press 91 for lamination, and then, and then the sponge is conveyed to a needle checking station to detect whether the sponge contains a grabbing needle or not, and finally the sponge is conveyed to a switching conveying platform 10, and the sponge at the switching conveying platform 10 is selected to be directly conveyed to the next procedure or sent to be subjected to needle removal treatment according to the detection result of the previous procedure.
