In one implementation, and referring to fig. 1-4 together, the vacuum chuck a may include at least a base 1. The susceptor 1 has a plurality of vacuum chambers 10, and the plurality of vacuum chambers 10 are not connected to each other. The top surface of the base 1 is provided with a plurality of adsorption ports 11, and each vacuum cavity 10 is respectively communicated with the plurality of adsorption ports 11. In other words, each vacuum chamber 10 communicates with a plurality of adsorption ports 11, and each adsorption port 11 communicates with only one vacuum chamber 10. So, because each other do not communicate between each vacuum chamber 10, when the tight product of needs absorption clamp, place the top that corresponds absorption port 11 with the product, then only need with the vacuum chamber 10 and the outside main pipeline 2 intercommunication that adsorbs that adsorb port 11 intercommunication, can adsorb the product through the absorption port 11 that corresponds, and then realize pressing from both sides tightly the absorption of product, avoid too much absorption port 11 to expose outside influence adsorption pressure. That is, the number of the vacuum chambers 10 to be opened may be selected according to the shape of the corresponding product, so as to be suitable for different types of products.

It should be noted that which vacuum chamber 10 is specifically opened can be determined according to which vacuum chamber 10 the adsorption port 11 covered by the area of the surface to be fixed of the product is communicated with.

In practical application, a sealing plate 4 is connected to the bottom of the base 1. A vacuum chamber 10 is formed by the sealing plate 4 and the base 1. The sealing plate 4 may be a single piece, for example, one sealing plate 4 and the base 1 surround to form a plurality of vacuum chambers 10. Of course, it is also possible to use a plurality of sealing plates 4, as shown in fig. 2, each sealing plate 4 being used to form a separate vacuum chamber 10 with the susceptor 1. In addition, a plurality of mounting holes may be formed at both ends of the base 1, so that the base 1 can be conveniently connected to other devices. Folding handles can be arranged on two sides of the base 1, so that the vacuum sucker A can be conveniently taken.

In one implementation, this is done. The base 1 can be provided with a plurality of discharge ports 12 and a plurality of negative pressure ports 13. The plurality of drain ports 12 and the plurality of negative pressure ports 13 are respectively communicated with the plurality of vacuum chambers 10 in a one-to-one correspondence manner, that is, one drain port 12 and one negative pressure port are respectively communicated with one vacuum chamber 10 on the base 1. An on-off valve 14 is connected to each drain port 12. The opening or closing of the discharge port 12, and thus the pressure release, is controlled by the on-off valve 14. The vacuum cup further comprises a main conduit 2. One end of the main pipeline 2 is connected with a compressed air interface 21, and the other end of the main pipeline 2 is connected with a negative pressure pipe interface 22. The main pipeline 2 is respectively communicated with the vacuum cavities 10 through a plurality of negative pressure ports 13. Each vacuum chamber 10 can be controlled to be communicated with or closed off from the main pipe 2 for realizing. A control valve 15 is connected to each negative pressure port 13, and the control valve 15 controls opening and closing of the negative pressure port 13.

In practical applications, compressed air is first connected to the compressed air port 21, and then negative pressure is connected to the negative pressure pipe port 22. Next, the product is put on the plurality of adsorption ports 11. At this time, the control valve 15 is opened to form a negative pressure region in the vacuum chamber 10, so that the product is fastened to the adsorption ports 11 through the adsorption ports 11, thereby achieving adsorption.

Further, a negative pressure meter 3 is connected in series on the main pipeline 2 to detect whether the pressure in the main pipeline 2 meets the required requirements, and the use safety of the product is improved.

Among them, there are many arrangement ways between the vacuum chambers 10 and the susceptor 1. In an implementation, please refer to fig. 3, each vacuum chamber 10 is a rectangular chamber, and a plurality of vacuum chambers 10 are arranged in a linear array along the length direction of the susceptor 1.

In another practical implementation, please refer to fig. 5, each vacuum chamber 10 is a ring-shaped chamber, and several vacuum chambers 10 are concentrically arranged. Thus, the vacuum chuck a can be used for sucking and fixing a disk or a cylinder having an unnecessary size. For example, when the diameter of the bottom surface of the product is 10cm, the corresponding vacuum cavity 10 with the diameter of 10cm can be opened for adsorbing the product, the adsorption port 11 is reasonably utilized, and the adsorption effect is improved.

Based on the same inventive concept, please refer to fig. 6, the present application further provides an automatic clamp, which at least comprises a turning table 5 and the vacuum chuck a. The vacuum chuck A is connected to the overturning platform of the overturning worktable 5, so that the vacuum chuck A can overturn along with the overturning platform of the overturning worktable 5.

In this embodiment, after the product processing is accomplished, can drive vacuum chuck A through upset workstation 5 and overturn to the tilt state, then carry out the pressure release to the vacuum cavity 10 that corresponds on the vacuum chuck A, the product can slide down along with vacuum chuck A's top surface slope after that, conveys to in the subsequent handling by outside transfer apparatus.

Taking blowhead 6 as an example, blowhead 6 can set up towards vacuum chuck A's top surface to when the product unloading, carry out the supplementary product unloading that promotes, avoid the too big situation that leads to unable gliding of product and vacuum chuck A's top surface frictional force. Furthermore, since the blowhead 6 protrudes above the top surface of the vacuum chuck a, in some application scenarios, the blowhead 6 may interfere with the processing traveling route of the external processing equipment. In order to solve the problem, the base 1 can be connected with the telescopic cylinder 7, so that the base 1 is connected with the blowing head 6 through the telescopic cylinder 7, when a product is not in the blanking step, the telescopic cylinder 7 can drive the blowing head 6 to retract to the lower part of the top surface of the vacuum chuck 1, and the interference of normal processing is avoided. When the product is in the blanking step, the telescopic cylinder 7 drives the blowing head 6 to extend out.

Further, the base can also be connected with the gas blow head through telescopic cylinder, and when the product was not in the unloading step, telescopic cylinder can drive the gas blow head and withdraw to the below of vacuum chuck top surface to avoid interfering normal processing. When the product is in the unloading step, telescopic cylinder drives the gas blow head again and stretches out, assists the unloading, avoids the unable gliding stop of product situation on vacuum chuck.
