[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-3 The vacuum roller shown has strong substrate protection, including a vacuum roller body 1, with drive components 2 connected to both ends of the vacuum roller body 1, support feet 3 provided below the drive components 2, and a telescopic sealing component 4 installed inside the drive components 2, which moves on the inner wall of the vacuum roller body 1.

[0028] Specifically, the vacuum roller body 1 is provided with a plurality of adsorption holes 11;

[0029] Reference Figure 2-3 The drive assembly 2 includes a connecting seat 21 installed at both ends of the vacuum roller body 1. A docking ring 22 extends inward on one side of the connecting seat 21. The connecting seat 21 is installed outside the drive motor 23. A telescopic sealing assembly 4 is installed on one side of the drive motor 23.

[0030] Specifically, the telescopic sealing assembly 4 includes a telescopic cylinder 41, which has multiple stages, and a sealing ring 42 is provided at the end of the top telescopic cylinder 41. The sealing ring 42 is attached to the inner wall of the vacuum roller body 1.

[0031] Specifically, the sealing ring 42 is located on the outer wall of the front end of the telescopic cylinder 41, and the outer wall of the sealing ring 42 is provided with a sealing groove 43. A sealing ring 44 is installed in the sealing groove 43, and the sealing ring 44 contacts the inner wall of the vacuum roller body 1.

[0032] In this embodiment, the connecting seat 21 is fixed to both ends of the vacuum roller body 1 by multiple bolts 24 to ensure a firm connection. A mating ring 22 extending inward from one side of the connecting seat 21 connects to the inside of the end of the vacuum roller body 1, allowing the mating ring 22 to support the vacuum roller body 1 between the two connecting seats 21, thus providing stable support for the roller body. Then, the drive motor 23 is installed outside the connecting seat 21, completing the installation of the drive assembly 2.

[0033] Specifically, a telescopic sealing assembly 4 is installed on one side of the drive motor 23. The telescopic cylinder 41 of the telescopic sealing assembly 4 has multiple stages, and the size of each stage telescopic cylinder 41 is smaller than that of the previous stage telescopic cylinder 41. This structure facilitates telescopic operation. A sealing collar 42 is provided at the end of the top telescopic cylinder 41. The sealing collar 42 is located on the outer wall of the foremost end of the telescopic cylinder 41, and a sealing groove 43 is opened on the outer wall of the sealing collar 42. A sealing ring 44 is installed in the sealing groove 43 so that the sealing ring 44 can contact the inner wall of the vacuum roller body 1 to ensure a sealing effect.

[0034] Specifically, a negative pressure pipe 25 is installed between the two drive components 2, and the negative pressure pipe 25 is placed inside the vacuum roller body 1 so that it can rotate with the vacuum roller body 1.

[0035] Specifically, the telescopic cylinder 41 is driven by the drive motor 23, and the size of each telescopic cylinder 41 is smaller than the size of the previous telescopic cylinder 41.

[0036] Specifically, the connecting seat 21 is fixed to both ends of the vacuum roller body 1 by multiple bolts 24, and the docking ring 22 is connected to the inside of the end of the vacuum roller body 1, that is, the docking ring 22 supports the vacuum roller body 1 between the two connecting seats 21.

[0037] Specifically, a negative pressure pipe 25 is provided between the two drive components 2. The negative pressure pipe 25 is placed inside the vacuum roller body 1 and rotates with the vacuum roller body 1.

[0038] Specifically, the initial position of the telescopic sealing component 4 at both ends corresponds to the initial position of the adsorption holes 11 at both ends of the vacuum roller body 1, and both telescopic sealing components 4 at both ends move inward to close.

[0039] In this embodiment, after installation, the initial position of the telescopic sealing components 4 at both ends is adjusted so that they correspond to the initial position of the adsorption holes 11 at both ends of the vacuum roller body 1, and both telescopic sealing components 4 at both ends are in an inwardly closed state to prepare for subsequent operations.

[0040] In this embodiment, when the vacuum roller needs to be used to operate on the substrate, the drive motor 23 is started. The drive motor 23 drives the telescopic cylinder 41 to extend and retract. According to the actual working requirements, the extension and retraction length of the telescopic cylinder 41 is controlled, thereby adjusting the position of the sealing ring 42 on the inner wall of the vacuum roller body 1.

[0041] Specifically, when the telescopic sealing component 4 moves to the appropriate position, a negative pressure environment is formed inside the vacuum roller body 1 through the negative pressure pipe 25. Since the vacuum roller body 1 is provided with multiple adsorption holes 11, the substrate can be adsorbed onto the surface of the vacuum roller body 1 under the action of negative pressure, thereby achieving the fixation and transfer of the substrate.

[0042] Specifically, after the adsorption operation is completed, if it is necessary to seal the adsorption area, the drive motor 23 continues to drive the telescopic sealing component 4 to move inward, so that the sealing ring 44 on the sealing collar 42 tightly fits the inner wall of the vacuum roller body 1, sealing the adsorption hole 11, preventing external substances from entering the adsorption area, and playing a protective role for the substrate.

[0043] In this embodiment, the design of the sealing collar 42 and sealing ring 44 of the telescopic sealing component 4 effectively prevents external impurities, moisture, etc., from entering the interior of the vacuum roller body 1, avoiding contamination and damage to the substrate and providing a good protective environment for the substrate. For example, when processing high-precision electronic chip substrates, it can prevent dust, moisture, etc., from affecting the performance and quality of the chip.

[0044] Specifically, the combination of the adsorption pore 11 and the negative pressure tube 25 enables stable adsorption and transport of the substrate, preventing issues such as substrate shifting or wrinkling during transport and ensuring the flatness and integrity of the substrate. For example, in the production process of thin film substrates, it can ensure uniform transport of the film and improve product quality.

[0045] In this embodiment, the multi-stage design of the telescopic cylinder offers advantages: the multi-stage design of the telescopic cylinder 41 makes the telescopic sealing component 4 more flexible during movement, allowing the size and position of the adsorption area to be adjusted according to different working scenarios and substrate size requirements, thus meeting diverse production needs. For example, when processing substrates of different specifications, the length of the telescopic cylinder 41 can be adjusted to adapt to the size of the substrate.

[0046] Specifically, the connecting seat 21 supports the vacuum roller body 1 through the mating ring 22, and with the addition of bolts 24 for fixation, the entire vacuum roller structure becomes more stable. This reduces vibration and misalignment during high-speed operation or long-term work, ensuring normal equipment operation and improving production efficiency.

[0047] In this embodiment, the bolt fixing facilitates disassembly: the connecting seat 21 is fixed to both ends of the vacuum roller body 1 by bolts 24. This method makes it easy to disassemble the connecting seat 21 when it is necessary to maintain, repair or replace parts inside the roller body, which is convenient for operators to operate and reduces maintenance costs and difficulty.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
