In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.

Only those parts relevant to the embodiments of the present utility model are shown for convenience of description.

Referring to fig. 1-4, the punching device comprises a machine 1, a pair of vertical plates 2 are arranged on the machine 1, a liftable upper pressing plate 3 is arranged between the vertical plates 2, a lower pressing plate 4 is arranged on the machine 1 and under the upper pressing plate 3, a pair of punching columns 5 capable of vertically moving are arranged on the machine 1 and outside the lower pressing plate 4, the upper pressing plate 3 corresponds to the punching columns 5, a pair of through holes 6 penetrating through the punching columns are formed in a matched mode, a guiding device is arranged on the front side of the vertical plates 2, and a pair of vision detection devices 23 are correspondingly arranged on the top of the upper pressing plate 3 and on the rear side of the punching columns 5.

In the leather production process, equidistant punching is generally required to be carried out on the leather so as to facilitate subsequent production of the leather. When the device is used for punching leather, the leather is firstly required to pass through the device and then is pulled by the traction mechanism. The traction mechanism is not the main point of the device and is not described in detail here.

When needs are punched to the leather, the leather falls on the lower pressing plate after passing through the guide device, and at the moment, the upper pressing plate descends towards the lower pressing plate and compresses the leather. And then the punching column vertically moves towards the leather material to punch holes until the top end of the punching column penetrates into the corresponding through hole, and then the punching of the leather material is completed. After punching, whether the holes on the leather meet punching requirements or not is detected through a visual detection device, and the phenomenon that the leather is prevented from being leaked to punch is avoided. In this device, the visual detection device may be an industrial camera 23, and the quality of punching is further improved by detecting by the industrial camera in a manner of uploading the photographed hole to the terminal for processing.

In this structure, the through-hole with the punching press post sets up relatively, when the cladding is compressed tightly by both top board, holding down plate, has realized the location before punching to the cladding, has guaranteed the punching accuracy to the cladding. In addition, the punching is achieved by driving the punching hole to move towards the position of the through hole and penetrate into the through hole, and generally, after the punching hole penetrates into the through hole, the punching action is completed. After punching is completed, the upper pressing plate and the lower pressing plate still compress the leather, so that the punching post is ensured to extract the leather, and the leather cannot deviate, and the punching quality is influenced. When the punching column draws out the leather material and returns to the initial position, the upper pressing plate returns to the original position, and the next group of punching is carried out on the leather material.

As a preferable structure, the rotating shaft 8 is rotatably installed in the machine 1, two ends of the rotating shaft 8 are provided with rotating plates 9, the front ends of the rotating plates 9 are rotatably connected with rotating rods 10, the top ends of the rotating rods 10 are rotatably connected with the corresponding positions of the upper pressing plates 3, and a driving assembly for driving the rotating shaft to rotate is arranged in the machine.

When the upper pressing plate needs to vertically lift, the driving assembly drives at the moment to drive the rotating shaft to rotate, and when the rotating plate rotates, the two rotating plates also rotate at the moment to drive the rotating rod to move up and down, and the upper pressing plate can move up and down under the driving of the rotating rod. If the upper pressing plate is to move downwards, the front end of the rotating plate rotates downwards at the moment, and the rotating rod drives the upper pressing plate to move downwards. The driving assembly can drive the rotating shaft to rotate by a motor, drive the rotating shaft to rotate by an air cylinder and the like. For example, a cylinder drives a rotating shaft to rotate. Specifically, the present utility model relates to a method for manufacturing a semiconductor device. And a driving cylinder is rotationally arranged in the machine table and is rotationally connected with the rotating shaft through a rotating block, and the rotating shaft is driven to rotate through the driving cylinder so as to achieve the purpose of lifting the upper pressing plate.

Further as a selection earlier structure, be equipped with diaphragm 13 in the board 1, be equipped with mounting panel 14 on the diaphragm 13, mounting panel 14 both ends all are equipped with sliding sleeve 15, it has slide bar 16 to penetrate in the sliding sleeve 15, is equipped with link 17 between two slide bars 16, the link 17 top is equipped with punching press post 5, mounting panel 14 bottom is equipped with punching press cylinder 24 and punching press cylinder 24 drive shaft passes mounting panel 14 and is connected with the link 17 bottom.

In this device, when the punching press post is punched in the drive, then the punching press cylinder drives the link vertical movement so that drive the punching press post vertical movement. Generally, when the top of the punching column penetrates into the corresponding through hole, the punching column is used for punching the leather. When the connecting frame moves vertically, the sliding rod slides in the corresponding sliding sleeve at the moment, so that the stability of the connecting frame during vertical movement is improved.

In this structure, a baffle 18 is disposed on top of the upper platen 3. After punching is carried out for a period of time, the through holes are necessarily filled with waste materials of leather materials. When continuing to punch, waste material in the through-hole can be extruded, through set up at the top of top board when the baffle with prevent that the waste material from dropping to guider department.

In addition, the guiding device comprises a mounting frame 19, a rotating wheel 20 and a mounting rod 21 are respectively arranged at the front and back positions of the mounting frame 19 in a rotating mode, and pressing blocks 22 are arranged at two ends of the mounting rod 21 and face the rotating wheel 20.

The leather is guided by the guiding device in the punching process. The leather passes through the rotating wheel and passes through the mounting rod. At the moment, the pressing plates are slightly pressed at two ends of the leather so that the leather can be positioned and conveyed.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
