Description

Technical Field

[0001] This utility model relates to a vacuum adsorption component, belonging to the field of vacuum adsorption. Background Technology

[0002] Vacuum adsorption technology is a technique that uses the suction force generated in a vacuum to fix objects to a surface. It is widely used in industrial production, medical equipment, aerospace and other fields.

[0003] Vacuum adsorption technology creates a low-pressure environment, subjecting objects at atmospheric pressure to a significant pressure difference, thereby generating adsorption force. Its principle mainly involves two aspects: first, a pump extracts gas from the container, reducing the pressure inside to a vacuum; second, the low pressure difference under vacuum conditions generates adsorption force, firmly fixing the object to the surface.

[0004] With the increasing use of vacuum adsorption in industrial material handling, the requirements for its implementation are becoming more and more stringent. For example, when handling flat objects such as large, smooth surfaces like LCD screens and semiconductor silicon boards, in addition to requirements for adsorption force, there are also higher requirements for the flatness after adsorption to facilitate subsequent processing on the LCD screen or silicon board. However, traditional vacuum adsorption devices are only suction cups or sponges. Due to the excessive length of the suction cups and the uneven compression of the sponges, it is impossible to ensure that multiple vacuum adsorption devices maintain uniform flatness after adsorption, causing inconvenience in subsequent processing or bonding processes. Utility Model Content

[0005] The technical problem to be solved by this utility model is: to overcome the above problems, to provide an adjustable vacuum adsorption component that can improve the adsorption flatness.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A vacuum adsorption assembly includes a mounting part and a stroke assembly. The stroke assembly is mounted on the mounting part. The upper end of the stroke assembly is connected to a vacuum generator, and the lower end of the stroke assembly is connected to a vacuum suction device. The vacuum suction device is used to adsorb products. The stroke assembly can drive the vacuum suction device to move within a fixed stroke. The stroke assembly includes two support rod sleeves, both of which are fixedly mounted to the mounting part. The upper ends of the support rod sleeves extend out of the mounting part. The support rods are installed inside the support rod sleeves and can move up and down. The top ends of the two support rods are respectively sealed to the vacuum generator, and the free ends of the two support rods are connected to one vacuum suction device.

[0008] Preferably, the support rod includes an upper vacuum tube and a lower vacuum tube. The top end of the upper vacuum tube is sealed to the vacuum generator, and the end of the upper vacuum tube is sealed inside the lower vacuum tube. The upper vacuum tube communicates with the lower vacuum tube, and the upper vacuum tube can move sealed within the lower vacuum tube. A top limiting ring is provided at the top end of the lower vacuum tube connected to the upper vacuum tube. The top limiting ring restricts the final movement position of the upper and lower vacuum tubes. The lower vacuum tube moves up and down sealed within the support rod sleeve. The free end of the lower vacuum tube is sealed to the vacuum suction device, so that the vacuum generator communicates with the vacuum suction device through the upper and lower vacuum tubes.

[0009] Preferably, the stroke assembly is provided in two sets, and the two sets of stroke assemblies are fixedly installed on one of the mounting parts.

[0010] Preferably, the vacuum suction device is provided with a sealing bolt, which passes through the vacuum suction device and is sealed to the bottom end of the lower vacuum tube of one of the support rod sleeves of the stroke assembly.

[0011] Preferably, a spring is provided inside the support rod sleeve, with the upper end of the spring abutting against the inner wall of the support rod sleeve and the lower end of the spring abutting against the lower vacuum tube.

[0012] Preferably, the support sleeve is connected to the mounting part by a locking nut, and a washer is provided between the locking nut and the mounting part.

[0013] Preferably, the mounting part is a mounting plate, and the mounting plate is provided with mounting holes for fixed installation with the bracket.

[0014] Preferably, the upper end of the stroke assembly is connected to the vacuum generator via a quick-connect plug.

[0015] The beneficial effects of this invention are as follows: This invention controls the flatness of the adsorbed product through the stroke component, and can adjust the distance while adsorbing. When multiple vacuum adsorption components of this patent are assembled together, the flatness of the product can be guaranteed, and the precision can meet the needs of subsequent industrial operations such as further processing or bonding. It simplifies the steps of putting down the product and readjusting the flatness, and can adapt to the production needs of automated production lines. Furthermore, this invention simplifies the mounting part to a mounting plate, saving a lot of metal plate costs and reducing the load on the robotic arm. More vacuum adsorption components of this invention can be mounted on the robotic arm to expand the adsorption surface or increase the weight of the adsorbed product, making it applicable to a wider range of applications.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Example 1

[0022] like Figure 1 and Figure 2 The vacuum adsorption assembly of this utility model, as shown, includes a mounting part 1 and a stroke assembly 2. The mounting part 1 is preferably made of metal, but other rigid plastics can also be used. For the purposes of this utility model, the mounting part 1 is preferably made of a lighter material. The stroke assembly 2 is mounted on the mounting part 1. The upper end of the stroke assembly 2 is connected to a vacuum generator (not shown in the figure), which is externally connected via a pipe. The lower end of the stroke assembly 2 is connected to a vacuum suction device 5, which is used to adsorb products. The stroke assembly 2 can drive the vacuum suction device... The device 5 moves within a fixed stroke. The stroke assembly 2 includes two support rod sleeves 9, both of which are fixedly installed with the mounting part 1. The upper end of the support rod sleeve 9 extends out of the mounting part 1. A vertically movable support rod 14 is installed inside the support rod sleeve 9. The top ends of the two support rods 14 are respectively sealed and connected to the vacuum generator. The free ends of the two support rods 14 are connected to one vacuum suction device. This utility model uses two support rod sleeves to fix and connect the vacuum suction device, which minimizes the volume, ensures balance, and meets production needs.

[0023] This product directly connects the stroke assembly 2 to the vacuum generator, eliminating the need for an air passage in the mounting part 1. This reduces the volume to that of a sheet metal, significantly decreasing both size and weight. Since this invention is designed for use in multiple parallel configurations, it greatly reduces the overall load during large-scale use. Furthermore, this invention is typically mounted on a robotic arm, which usually has a fixed load. When the weight of the adsorption device is too large, the weight of the product it can adsorb is limited. This invention can increase the weight of the adsorbed product, and with the overall weight reduced, the operational accuracy can also be improved accordingly.

[0024] In a preferred embodiment, the support rod 14 includes an upper vacuum tube 13 and a lower vacuum tube 4. The top end of the upper vacuum tube 13 is sealed to the vacuum generator, and the end of the upper vacuum tube 13 is sealed inside the lower vacuum tube 4. The upper vacuum tube 13 communicates with the lower vacuum tube 4, and the upper vacuum tube 13 can move within the lower vacuum tube 4 in a sealed manner. This sealed movement means that the upper vacuum tube 13 is fitted onto the lower vacuum tube 4, and the two are relatively sealed but can still move. A top limiting ring is provided at the top end of the lower vacuum tube 4 where it connects to the upper vacuum tube 13, and the top limiting ring restricts the movement of the upper vacuum tube 13. 3. The final moving position of the lower vacuum tube 4 is generally determined by a corresponding sealing structure at the top limiting ring to seal the upper vacuum tube 13 and the lower vacuum tube 4. The lower vacuum tube 4 moves up and down in the support sleeve 9. For example, the lower vacuum tube 4 moves up and down in the support sleeve 9 via a linear bearing 3. Generally, a sealing structure is provided at the end of the support sleeve 9 to achieve a relative seal between the support sleeve 9 and the lower vacuum tube 4. The free end of the lower vacuum tube 4 is sealed to the vacuum suction device 5, so that the vacuum generator is connected to the vacuum suction device 5 through the upper vacuum tube 13 and the lower vacuum tube 4.

[0025] In a preferred embodiment, the stroke assembly 2 includes a plurality of support rod sleeves 9, all of which are connected to the vacuum suction device 5. The number of stroke assemblies 2 and the number of support rod sleeves 9 are set according to the weight of the adsorbed product. When the adsorbed product is heavy, the number of stroke assemblies 2 and support rod sleeves 9 can be increased as needed.

[0026] In a preferred embodiment, a sealing bolt 6 is provided inside the vacuum suction device 5. The sealing bolt 6 passes through the vacuum suction device 5 and is sealed to the bottom end of the lower vacuum tube 4 of one of the support rod sleeves 9 of the stroke assembly 2. After the sealing bolt 6 seals the bottom end of the lower vacuum tube 4, when high-pressure gas from the vacuum generator is introduced, it will press against the sealing bolt 6 and apply downward pressure. Since the upper vacuum tube 13 and the lower vacuum tube 4 can move relative to each other, the high-pressure gas will push the lower vacuum tube 4 downward, thereby driving the vacuum suction device 5 downward. The other support rod sleeves 9 are connected by through-hole bolts 7, so that at least one of the multiple support rod sleeves 9 is used for height adjustment. The support rod sleeve 9 with through-hole bolts 7 is used for adsorbing products.

[0027] In a preferred embodiment, a spring 12 is provided inside the support sleeve 9. The upper end of the spring 12 abuts against the inner wall of the support sleeve 9, and the lower end abuts against the lower vacuum tube 4. During the up-and-down movement of the lower vacuum tube 4, the spring 12 can play a buffering role and provide additional elastic force during the movement.

[0028] In a preferred embodiment, the support sleeve 9 is connected to the mounting part 1 via a locking nut 10, and a gasket 11 is provided between the locking nut 10 and the mounting part 1.

[0029] In a preferred embodiment, the mounting part 1 is a mounting plate, and the mounting plate is provided with mounting holes 15 for fixed installation with the bracket. After simplifying the mounting part 1 into a mounting plate, the overall volume is greatly reduced. Compared with products that have air passages connected to the stroke component 2 in the mounting part 1, this product directly connects the stroke component 2 to the vacuum generator. The mounting part 1 does not need to have air passages, and its volume can be reduced to a sheet material. This saves costs and reduces weight. Specifically, as shown below... Figure 2 As shown, when multiple vacuum adsorption components of this invention are installed side by side, the overall weight will increase due to the accumulation of the number. This patent has a smaller size and weight, and is more convenient to use.

[0030] In a preferred embodiment, the upper end of the stroke assembly 2 is connected to the vacuum generator via a quick-connect plug 8.

[0031] Example 2

[0032] The vacuum adsorption method of the vacuum adsorption component described in Example 1 specifically includes the following steps:

[0033] (1) The vacuum adsorption assembly is brought close to the product to be adsorbed. The vacuum generator generates a vacuum and connects the vacuum suction device 5 through the stroke assembly 2 without the sealing bolt 6, so that the vacuum suction device 5 adsorbs the product.

[0034] (2) After the product is adsorbed, high-pressure gas is introduced into the stroke assembly 2 of the connecting sealing bolt 6 through the vacuum generator. The high-pressure gas rushes into the upper vacuum tube 13 and the lower vacuum tube 4, pushing the lower vacuum tube 4 to move downward, so that the top limiting ring of the lower vacuum tube 4 is limited to the upper vacuum tube 13.

[0035] (3) The vacuum generator continues to supply high-pressure gas to the stroke assembly 2 of the sealing bolt 6 until the product processing or bonding is completed, and then the supply is stopped.

[0036] (4) The vacuum generator supplies high-pressure gas into the stroke assembly 2 that is not connected to the sealing bolt 6, thereby disrupting the vacuum environment and causing the vacuum suction device 5 to stop adsorbing and detach from the product, thus completing the entire adsorption process.

[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
