Description

Technical Field

[0001] This utility model relates to the field of workbench technology, specifically to a vacuum adsorption platform. Background Technology

[0002] The adsorption platform works by creating a vacuum environment to generate adsorption force, thus fixing objects in place. When the vacuum pump starts, it draws air from the platform's surface, reducing the pressure. As the pressure decreases, the density of air molecules decreases, resulting in a stronger adsorption force. When an object is placed on the platform, the vacuum pump begins to draw air, creating a vacuum environment. This creates an inward pressure difference between the air molecules and the platform, generating an adsorption force. Once the object is adsorbed onto the platform, the vacuum pump maintains the pressure and ensures the adsorption force is strong enough to maintain the object's stability.

[0003] In the market, the basic structure of an adsorption platform typically includes a panel, frame, filler, and base plate. Most existing fillers are honeycomb-shaped, installed inside the adsorption platform cavity to provide ventilation and support; the quality of ventilation directly affects the platform's suction power, while the strength of the support directly affects the platform's resistance to pressure.

[0004] When manufacturing a vacuum adsorption platform, through holes are provided on both the panel and the base plate. These through holes are divided into straight through holes (a single cylindrical channel penetrating the panel or base plate without steps or changes in diameter) and stepped holes (a stepped structure with different diameters). Straight through holes have the advantages of simple structure, low processing cost, low airflow resistance, and fast vacuum response, making them suitable for adsorbing flat, thin, or rigid workpieces. However, they require a high degree of surface flatness; slight deformation or unevenness in the workpiece can easily lead to air leakage and a decrease in adsorption force. Stepped holes can adapt to uneven or flexible workpieces (such as soft materials and curved surfaces), providing more stable adsorption. The stepped structure can adjust the airflow speed and pressure distribution, making them suitable for applications with complex workpieces, uneven surfaces, high sealing requirements, or those requiring precise airflow control.

[0005] Traditionally, stepped holes on panels or base plates are made by first drilling a through hole and then milling another stepped hole. After processing, the panel / base plate is then fixed to the honeycomb support structure. This processing method results in reduced processing efficiency and excessively high processing costs. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum adsorption platform that has the advantages of high processing efficiency and low production cost.

[0007] A vacuum adsorption platform includes a panel, a frame, and a base plate. The panel and base plate are connected opposite each other to the two sides of the frame. The panel, frame, and base plate cooperate to form an accommodating cavity. The base plate and / or the frame are provided with air inlets for connecting to an external air source. The accommodating cavity is filled with supporting components.

[0008] The panel includes a first panel and a second panel. The first panel includes an adsorption surface and a back surface. The first panel is provided with a plurality of through first adsorption holes. The first adsorption holes include a plurality of stamped parts formed by stamping and each stamped part is provided with an adsorption through hole. The plurality of stamped parts form a recessed part on the side facing the adsorption surface and a protruding part on the side facing the back surface.

[0009] The second panel is provided with second adsorption holes that correspond one-to-one in number and position to the first adsorption holes;

[0010] The second panel is fixedly connected to one side of the protruding part of the first panel. The depth of the second adsorption hole is greater than or equal to the protruding thickness of the protruding part, and the first adsorption hole and the second adsorption hole are connected to each other.

[0011] The supporting components are fixedly installed between the base plate and the second panel.

[0012] By adopting the above technical solution, since the stepped holes of the panel are first stamped into the adsorption surface by a stamping process and then drilled, the production efficiency is higher and the production cost is lower compared with the traditional process of drilling first and then milling the steps. At the same time, a relatively thin panel can be selected for production and processing according to actual needs. However, since the stamping part is formed by stamping, a recessed part is formed on one side and a protruding part is formed on the other side. The second panel is directly installed on the side of the first panel with the protruding part, so that the side of the panel facing the support member is still flat, and the support member can still be installed flat on the panel.

[0013] Preferably, the support member is mainly composed of several stamped support pieces that are fixedly connected. The support piece includes an outwardly protruding yang part and an inwardly recessed yin part, with the yang and yin parts alternately connected. The yin part of one support piece can be matched with the yang part of another support piece to form a honeycomb unit. Each support piece is provided with a hollow through hole.

[0014] By adopting the above technical solution, the traditional aluminum foil support sheet is replaced with a stamped metal support sheet, which greatly improves the production efficiency of the support sheet and support components, and also improves the pressure resistance and ventilation of the support sheet. In addition, the support sheet, as a basic unit, can be stacked for transportation and storage, saving space.

[0015] Preferably, the support member is mainly composed of several stamped support pieces that are fixedly connected. Each support piece is provided with a hollow through hole, and the several support pieces are fixedly connected in a crisscross pattern to form several hollow units in the shape of triangles, squares, rectangles, octagons, or trapezoids.

[0016] By adopting the above technical solution, since the metal support sheet is stamped, the support component can be selected from the common honeycomb shape, or other common geometric shape units can be used to form the overall support component. Users can choose the structure of the internal support component as needed based on dimensions such as shear resistance, deformation resistance, axial load capacity, compressive strength, production cost, and internal air circulation.

[0017] Preferably, each support piece has a notch at the junction of its male and female portions, the notch being located on the side facing the panel and / or the base plate.

[0018] Preferably, each support piece has a reinforcing rib near the junction of the male and female parts, and the reinforcing rib is formed by stamping.

[0019] Preferably, each support piece has a reinforcing block near the junction of the male and female parts, and the reinforcing block is fixedly connected to the female and male parts.

[0020] By adopting the above technical solutions, the notch, reinforcing ribs, and reinforcing blocks can all effectively improve the stability of the support sheet and prevent the angle between the male and female parts from deforming when the support sheet is subjected to external pressure. This ensures that the adsorption performance of the vacuum adsorption platform remains stable even after long-term operation.

[0021] Preferably, the adsorption holes on the panel are evenly distributed in an array, and the positive and negative parts of each support sheet are equilateral, with the same number of adsorption holes in each honeycomb unit.

[0022] By adopting the above technical solution, the compressive strength of each honeycomb cell in the area supported by the entire support component is balanced, and the internal airflow is balanced, thereby effectively improving the adsorption performance, compressive strength, and service life of the vacuum adsorption platform.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0029] Example 1

[0030] A vacuum adsorption platform with a support member 2 includes a panel 1, a frame 3, a base plate 4, and a support member 2.

[0031] The panel 1 and the base plate 4 are connected to each other on both sides of the frame 3. The panel 1, the frame 3 and the base plate 4 cooperate to form an accommodating cavity, and the supporting member 2 is fixed in the accommodating cavity.

[0032] The base plate 4 and / or frame 3 are provided with air inlets for connecting to an external air source, which provides adsorption force for the entire vacuum adsorption platform.

[0033] The panel 1 includes a first panel 101 and a second panel 102. The first panel 101 includes an adsorption surface and a back surface. The first panel 101 has a plurality of first adsorption holes 1011. The first adsorption holes 1011 include a plurality of stamped parts formed by stamping and each stamped part is provided with an adsorption through hole. The plurality of stamped parts form a recessed part on the side facing the adsorption surface and a protruding part on the side facing the back surface.

[0034] It should be noted that traditionally, each stepped adsorption hole 11 includes a through hole and a milled stepped hole. This traditional processing method is inefficient, and because the stepped hole needs to be milled, the thickness of the panel 1 cannot be too thin, resulting in a high production cost for the entire panel 1. In contrast, the stepped hole of the panel 1 in this invention is created by first stamping a recessed step on the adsorption surface using a stamping process, followed by drilling. This allows for the use of a relatively thin metal panel 1 for processing. Furthermore, all adsorption holes 11 on a single panel 1 can be stamped in one operation, and all through holes can be processed in one operation, significantly improving production efficiency and reducing production costs.

[0035] The second panel 102 is provided with second adsorption holes 1021 that correspond one-to-one in number and position to the first adsorption holes 1011 of the first panel 101. The second panel 102 is fixedly connected to one side of the protruding part of the first panel 101. The depth of the second adsorption hole 1021 is greater than or equal to the protruding thickness of the protruding part, and the first adsorption hole 1011 and the second adsorption hole 1021 are connected to each other. The support member 2 is fixedly installed between the base plate 4 and the second panel 102.

[0036] It should be noted that since the stamped part is formed by stamping, one side will form a concave part and the other side will inevitably form a protruding part. If the supporting component interferes with the protruding part, it will be difficult to form a flat vacuum adsorption platform. However, the second panel 102 is directly installed on the side of the first panel 101 with the protruding part (the fixed connection between the first panel 101 and the second panel 102 can be laser welding, spot welding, bonding, etc.), so that the side of the panel 1 facing the supporting component 2 is still flat, and the supporting component 2 can still be installed flat on the panel 1.

[0037] The support member 2 is mainly composed of several stamped support pieces 21 fixedly connected together. Each support piece 21 includes an outwardly protruding male portion 211 and an inwardly recessed female portion 212. The male portions 211 and female portions 212 are alternately connected, and the female portion 212 of one support piece 21 can be mated with the male portion 211 of another support piece 21 to form a honeycomb unit. Each support piece 21 is provided with a hollow through hole 216. It should be noted that the traditional aluminum foil support piece 21 is replaced with a stamped metal support piece 21, and different metal support pieces 21 are then welded into the entire support member 2. This greatly improves the production efficiency of the support piece 21 and the support member, and also improves the pressure resistance and ventilation of the support piece 21. In addition, the support piece 21, as a basic unit, can be stacked for transportation and storage, saving space.

[0038] Each support piece 21 has a notch 213 at the junction of the male part 211 and the female part 212. The notch 213 is located on the side facing the panel 1 and / or the base plate 4. Preferably, the notch 213 can be triangular or inverted trapezoidal.

[0039] Each support piece 21 is provided with a reinforcing rib 215 near the junction of the male part 211 and the female part 212. The reinforcing rib 215 is formed by stamping, that is, one side of the reinforcing rib 215 is concave and the other side is protruding. The reinforcing rib 215 can be provided alone in the male part 211, or it can be provided alone in the female part 212, or both the male part 211 and the female part 212 can be provided with reinforcing rib 215.

[0040] Each support piece 21 is provided with a reinforcing block 214 at the junction of the male part 211 and the female part 212. The reinforcing block 214 is fixedly connected to the female part 212 and the male part 211. The reinforcing block 214 can be provided at the junction of the male part 211 and the female part 212 and on the side close to the panel 1, or it can be provided on the side close to the bottom plate 4, or both sides can be provided with reinforcing blocks 214.

[0041] The notch 213, reinforcing rib 215, and reinforcing block 214 can all effectively improve the stability of the support plate 21, preventing deformation of the angle between the male and female portions 211 and 212 when the support plate 21 is subjected to external pressure. This ensures that the vacuum adsorption platform's adsorption performance remains stable even after long-term operation. In actual production and processing, any one or any combination of the notch 213, reinforcing rib 215, and reinforcing block 214 can be used. To maximize the stability of the support member 2, it is preferable to include all three: notch 213, reinforcing rib 215, and reinforcing block 214.

[0042] The adsorption holes 11 on the panel 1 are evenly distributed in an array, and the positive part 211 and the negative part 212 of each support piece 21 are equilateral. The number of adsorption holes 11 in each honeycomb unit is the same.

[0043] By adopting the above technical solution, the compressive strength of each honeycomb unit in the area supported by the entire support component 2 is balanced, and the internal airflow is balanced, thereby effectively improving the adsorption performance, compressive strength, and service life of the vacuum adsorption platform.

[0044] Example 2

[0045] Unlike Embodiment 1, the support member 2 is mainly composed of several stamped support pieces 21 fixedly connected together. Each support piece 21 has a hollow through hole 216, and several support pieces 21 are fixedly connected in a crisscross pattern to form several hollow units in the shape of triangles, squares, rectangles, octagons or trapezoids.

[0046] Since the metal support sheet 21 is made by stamping, the support component 2 can be selected from the common honeycomb shape, or other common geometric shape units can be used to form the integral support component 2. Users can select and set the structure of the internal support component 2 as needed according to dimensions such as shear resistance, deformation resistance, axial load capacity, compressive strength, production cost, and internal air circulation.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
