Description

Technical Field

[0001] The present invention relates to the technical field of automatic crimping, and in particular to a crimping platform capable of being controlled by partitions. Background Art

[0002] In the field of automatic crimping production, automated production equipment has extremely high requirements for positioning accuracy before product processing. During the automatic crimping process, customer products are affected by factors such as material properties, manufacturing processes, storage and transportation, and are prone to warping and deformation. This will make it difficult for the product to fit accurately with the carrier surface, resulting in an offset in the contact position between the crimping head and the product and uneven pressure distribution. This not only seriously affects the crimping quality, but also significantly reduces production efficiency due to frequent equipment debugging and rework of products. The existing technology often adopts a microporous platform structure, based on the principle of negative pressure adsorption, using vacuum suction to adsorb warped products flat and fix them to the platform surface, ensuring that the product is in an ideal flat state during processing. However, the currently commonly used one-piece whole-piece carrier, when adapting to products of different specifications, is uneven due to the uneven incoming product materials, and the carrier area not covered by the product will form a gas leakage channel, resulting in a serious loss of pressure in the negative pressure system, a significant decrease in adsorption force, and poor product adsorption effect. It is impossible to meet the high-precision crimping requirements, which ultimately affects the yield rate of the crimping process and becomes a key technical problem that restricts the improvement of automated production quality and efficiency.

[0024] The following is a clear and complete description of the technical solutions in the specific embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] The embodiment of the present invention provides a press-fitting platform that can be controlled in different zones. Figures 1 to 5As shown, the crimping platform consists of two main parts: an adsorption platform 1 and a control unit 2. The adsorption platform 1 features a support surface for placing the product to be tested. This support surface is physically divided into multiple independent adsorption zones. Each adsorption zone can be flexibly adapted to a variety of test products of varying specifications, shapes, and sizes through different combinations, significantly enhancing the platform's versatility and applicability. The control unit 2 comprises a negative pressure source 201, negative pressure lines 202 independently connected to each adsorption zone, and a control valve 203 installed on each negative pressure line 202. The negative pressure source 201, the power source of the entire adsorption system, provides stable vacuum power for the adsorption process. The independently connected negative pressure lines 202 ensure that each adsorption zone receives independent vacuum suction. The control valve 203 independently adjusts the vacuum level of the corresponding adsorption zone according to the specific adsorption requirements of the product to be tested, precisely controlling the adsorption force in each zone. This ensures effective adsorption while effectively preventing negative pressure leakage in areas not covered by the product, significantly improving the stability and adsorption efficiency of the negative pressure system.

[0026] Multiple adsorption areas adopt a layered and progressive layout design, specifically as follows: a central adsorption area 101 is provided in the center of the carrying surface. When enabled alone, this area can accurately adsorb the smallest size of the product to be tested, ensuring the stable positioning of small-sized products. Outside the central adsorption area 101, a first extension area consisting of multiple adsorption areas is provided. The adsorption areas are arranged in sequence. By flexibly combining the central adsorption area 101 with one or more adsorption areas in the first extension area, it is possible to adapt to the adsorption of products to be tested within the first size range, effectively expanding the applicable size range of the carrier. Outside the first extension area, an annular adsorption area 102 is arranged around it. The annular area is combined with the central adsorption area 101 and one or more adsorption areas in the first extension area to meet the adsorption requirements of products to be tested within the second size range, further improving the adaptability of the carrier to products of different specifications. In addition, a second expansion area is provided outside the annular adsorption area 102, and is also composed of multiple adsorption areas, each of which is arranged in sequence. By combining the central adsorption area 101, the annular adsorption area 102, one or more adsorption areas within the first expansion area, and one or more adsorption areas within the second expansion area, it is possible to adapt to the adsorption of products to be tested within a third size range, achieving stable adsorption of larger products. The third expansion area, set outside the second expansion area, is also composed of multiple adsorption areas and is arranged in sequence. When combined with the central adsorption area 101, the annular adsorption area 102, the first expansion area, and one or more adsorption areas within the second expansion area, it can meet the adsorption requirements of products to be tested within a fourth size range, significantly improving the platform's adaptability to oversized products.

[0027] It is worth noting that part or all of the adsorption areas within the first expansion area, the second expansion area, and the third expansion area are composed of two or more physically separated but interconnected sub-areas. These sub-areas are arranged according to preset array, symmetry, grid or ring rules in each expansion area. Their shapes can be designed into various geometric forms such as rectangles, circles or polygons according to actual needs. Through the combined design of such sub-areas, the adsorption force distribution can be further optimized, and efficient and stable adsorption and fixation can be achieved for products with complex shapes. In other specific embodiments, the layout of multiple adsorption areas can be adaptively designed according to actual production needs, specification characteristics of the products to be tested, and process requirements, such as using linear arrangement, matrix distribution, irregular polygon combination or other special layout forms. The present invention does not make specific limitations on this, so as to fully meet the flexible adaptation needs in different application scenarios.

[0028] In this embodiment, the bearing surface of the adsorption platform 1 constructs a hierarchical nested layout structure, which is divided into 13 independently controllable adsorption areas. Among them, the central adsorption area 101 serves as the basic unit, and its size is precisely adapted to 6-inch products, providing precise adsorption positioning for the smallest specification products. A first expansion area is set around the central adsorption area 101, which is composed of three adsorption areas arranged in sequence. Each adsorption area contains two symmetrical sub-areas along the first direction (X-axis direction) and with the center line of the central adsorption area 101 as the axis of symmetry, and the sub-areas in the same adsorption area are interconnected by air paths through an internal connecting structure. The central adsorption area 101 cooperates with the first expansion area to provide stable adsorption support for products in the range of 6-11 inches. Outside the first expansion area, a rectangular ring-shaped annular adsorption area 102 is provided, the size of which corresponds to the boundary of a 13-inch product, forming an intermediate layer adsorption structure. The second expansion area and the third expansion area are arranged in sequence outside the annular adsorption area 102, together forming an outer layer adsorption structure. The second expansion area includes 4 adsorption areas, each of which is composed of two symmetrically distributed sub-areas, of which the sub-areas of two adsorption areas are symmetrically distributed along the first direction (X-axis) with the center line of the annular adsorption area 102, and the sub-areas of the other two adsorption areas are symmetrically distributed along the second direction (Y-axis) with the center line of the annular adsorption area 102, realizing a two-dimensional adsorption expansion function through an orthogonal symmetrical layout. The second expansion area is combined with the inner layer structure to meet the adsorption needs of 6-17 inch products. As the third expansion area of ​​the outermost structure, there are 4 adsorption areas, and its design takes into account both symmetrical layout and functional optimization: 3 of the adsorption areas each contain two symmetrically distributed sub-areas, and the other adsorption area is composed of four sub-areas. Specifically, the two adsorption areas with twin sub-areas have sub-areas arranged in sequence along the first direction (X-axis direction) with the center line of the second expansion area as the axis of symmetry; the other adsorption area containing twin sub-areas has sub-areas symmetrically arranged along the second direction (Y-axis direction) with the center line of the second expansion area; and the adsorption area containing four sub-areas, each sub-area is respectively arranged at the four corners of the bearing surface, and is diagonally symmetrically distributed with the geometric center of the bearing surface as the symmetry reference point. This design can not only effectively adsorb the edge area of ​​large-sized products to be tested, but also achieve uniform distribution of adsorption force through symmetrical distribution, so that the adsorption platform 1 can be adapted to products to be tested ranging from 6 inches to 22 inches, meeting the high-precision crimping requirements under different working conditions. The above-mentioned multi-level and multi-dimensional symmetrical expansion design allows the adsorption areas to be flexibly combined according to the product size, while ensuring the adsorption stability, minimizing the negative pressure leakage in the uncovered area, and significantly improving the energy efficiency and adaptability of the system.

[0029] The adsorption platform 1 in this embodiment is mainly composed of an upper plate 3, a lower plate 4 and a sealing structure. Among them, the upper surface of the upper plate 3 serves as a bearing surface, and a number of micropores are evenly distributed on it for adsorbing the product to be tested. The lower plate 4 is provided with independent cavities corresponding to 13 adsorption areas on the side facing the upper plate 3. Each cavity has a specific shape and size to adapt to the functional requirements of the corresponding adsorption area. The sealing structure is arranged between the upper plate 3 and the lower plate 4. Through a precise assembly process, it is ensured that an independent and sealed adsorption space is formed between each cavity and the area corresponding to the upper plate 3, effectively preventing the leakage of negative pressure gas and ensuring the adsorption effect. On the lower plate 4, there is a gas path channel that is separately connected to each cavity. One end of the gas path channel is connected to the corresponding cavity, and the other end is connected to the negative pressure pipeline 202, so that negative pressure gas can be introduced into the adsorption space through the negative pressure pipeline 202 to achieve adsorption and fixation of the product. In order to further improve the adsorption performance and energy efficiency of the adsorption platform 1, the micropores in each adsorption area adopt a differentiated density distribution design, specifically following the distribution rule of gradually decreasing from the center of the bearing surface to the outside. This design is based on the adsorption force characteristics of the product. The micropores are densely arranged in the central area of ​​the bearing surface, which can gather more negative pressure channels in a limited space, form a high-intensity adsorption force, and ensure the precise positioning and firm fixation of the center position of the product; while the micropore distribution density is appropriately reduced in the outer area of ​​the bearing surface. On the one hand, it can avoid stress concentration damage to the edge of the product due to excessive adsorption force. On the other hand, by reducing the leakage area of ​​the negative pressure gas, a dynamic balance of "gas adsorption amount greater than leakage amount" is formed. While ensuring the adsorption effect, the negative pressure gas consumption is significantly reduced, and the energy efficiency of the system is improved. In addition, in other specific embodiments, the density of the micropore layout can be flexibly adjusted according to the material characteristics, size specifications and actual process requirements of the product to be tested. For example, for products with a smooth surface and uniform texture, a micropore layout with uniform density can be adopted; for products with special shapes or high adsorption requirements, the local micropore density can be optimized in a targeted manner. The present invention does not impose a sole limitation on the specific implementation of the micropore layout density, so as to fully cover a variety of application scenarios and technical solutions.

[0030] In addition, the four sides of the upper plate 3 of the support surface of the adsorption platform 1 are provided with scales. The scales are arranged along the edge of the upper plate 3 and are symmetrically marked with the geometric center of the adsorption platform 1 as the reference. The scale lines clearly mark the length values, and the minimum scale accuracy can be customized according to actual needs. Through the four-sided scale, the operator can intuitively obtain the placement coordinates of the product to be tested in the X-axis and Y-axis directions, achieving fast and accurate positioning. Especially when adapting to products of different sizes, it can effectively reduce manual positioning deviations, improve the efficiency and accuracy of adsorption positioning, and avoid poor crimping problems caused by positioning errors. Moreover, the scale setting cooperates with the layered and nested adsorption area structure without affecting the functional realization of each adsorption area, and together meet the needs of high-precision crimping operations.

These improvements and modifications also fall within the scope of protection of the claims of the present invention.
