[0025] The following detailed description of the embodiments of the present application is provided in conjunction with the accompanying drawings and examples. The detailed description of the following examples and the accompanying drawings are intended to illustrate the principles of the present application, but are not intended to limit the scope of the present application. The present application may be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but rather includes all technical solutions within the scope of the claims.

[0026] The present application provides these embodiments to make this application thorough and complete, and to fully express the scope of this application to those skilled in the art.

"Perpendicular" does not mean perpendicular in the strict sense, but rather means within the tolerance range. "Parallel" does not mean parallel in the strict sense, but rather means within the tolerance range. "Include" or "comprising" and similar terms mean that the elements preceding the word include the elements listed after the word, and do not exclude the possibility of other elements being included.

[0029] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediary.

[0030] All terms used in this application have the same meaning as understood by one of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, common dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and should not be interpreted in an idealized or highly formal sense, unless explicitly defined as such herein.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0032] like Figure 1-Figure 3 As shown, in some embodiments, a contoured vacuum chamber adsorption structure includes a product carrying device 1 and an adsorption connecting device 2. The product carrying device 1 is used to be connected to a vacuum pump or a vacuum generator to generate negative pressure, and the negative pressure is transmitted to the product carrying device 1. The product carrying device 1 injects the adsorbed product.

[0033] The product carrier 1 includes an integrally formed vacuum chamber insert 101, a peripheral vacuum chamber stop 102, and a product positioning platform 103. The entire product carrier 1 is a machined part made of SUS303 and is designed according to the shape and size of the adsorbed product. The peripheral vacuum chamber stop 102 is formed into a closed ring to ensure the sealing between the contact surface with the product. The product positioning platform 103 is located on the inner side of the peripheral vacuum chamber stop 102. An adsorption space 104 is formed between the product positioning platform 103 and the peripheral vacuum chamber stop 102. The size of the adsorption space 104 is designed according to the shape and size of the adsorbed product. The product is located in the adsorption space 104. The product is a plastic or aluminum insert, non-magnetic, with a small insert size and an adsorption surface less than 2mm. The gap between the product positioning platform 103 and the product is 0.02mm-0.05mm to ensure positioning accuracy.

[0034] The suction connection device 2 includes a vacuum chamber sealing plate 201, a vacuum suction head 202, and a product ejector pin 203, disposed below the vacuum chamber insert 101. The vacuum chamber sealing plate 201 is connected to the lower end surface of the vacuum chamber insert 101 and is fixed to the lower end surface of the vacuum chamber insert 101 via M3 bolts. The vacuum suction head 202 can be connected to a vacuum pump or vacuum generator to generate negative pressure suction. Vacuum suction holes 204 are formed through the vacuum chamber sealing plate 201 and the vacuum chamber insert 101. One end of the vacuum suction hole 204 connects to the suction space 104 and the other end connects to the vacuum suction head 202. The vacuum suction holes 204 absorb the contact area between the object and the product, changing the air pressure in that area from normal pressure to negative pressure. The pressure difference between the external atmospheric pressure and this negative pressure is utilized to achieve the purpose of suctioning the object. In this specific embodiment, there are four vacuum suction holes 204, symmetrically distributed at the bottom of the suction space 104, generating a more uniform suction force and ensuring balanced force across the product.

[0035] The cross-section of the vacuum chamber insert 101 is capable of covering the vacuum chamber sealing plate 201, which seals the vacuum chamber and prevents air leakage. Made of SUS304, the sealing plate 201 and the vacuum chamber insert 101 are perforated with ejector holes 205, which extend into the adsorption space 104. The product ejector pins 203 are inserted into these holes. The number of ejector holes 205 and product ejector pins 203 is the same. After the product ejector pins 203 are aligned with the mold, the product is pushed into the mold. Both the number of ejector holes 205 and the number of product ejector pins 203 are six, evenly spaced, ensuring a more uniform force when pushing the product.

[0036] In some embodiments, to prevent the vacuum chamber insert 101 from being installed upside down, anti-slip features are provided on the outer edge of the vacuum chamber insert 101. In this embodiment, the vacuum chamber insert 101 has a rectangular cross-section. This anti-slip feature utilizes a straight chamfer on one corner of the vacuum chamber insert 101, while the other corners have rounded chamfers. This ensures that when the vacuum chamber insert 101 is installed upside down, the straight chamfer and the rounded chamfer will not misalign, preventing installation. This ensures that the vacuum chamber insert 101 can be installed in the normal direction.

[0037] In some other embodiments, in addition to the above-mentioned technical features, the top surface height of the product positioning platform 103 is higher than the top surface height of the outer vacuum chamber baffle 102. The product positioning platform 103 is first inserted into the inner circle of the product to perform an initial positioning of the product, so that the adsorption accuracy is higher.

[0038] This application proposes a contoured vacuum chamber suction structure that can be widely used in machining, automated production lines, robotics, and other fields, particularly excelling in handling irregularly shaped, thin-walled structural parts. By utilizing new technologies and methods, and continuously optimizing the suction cup structure and vacuum system performance, the development of contact vacuum suction technology can be driven toward adaptability to multiple working conditions, multi-shape clamping, and high efficiency and energy conservation.

[0039] So far, the various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.

[0040] Although some specific embodiments of the present application have been described in detail through examples, those skilled in the art will understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present application. Those skilled in the art will understand that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present application. In particular, as long as there are no structural conflicts, the various technical features mentioned in the various embodiments may be combined in any manner.
