Technical Field

[0001] This application relates to the field of cleanroom transport, and more particularly to roller transport devices. Background Technology

[0002] With the continuous development of automated manufacturing, high-end manufacturing scenarios such as semiconductor automation equipment have extremely stringent requirements for the cleanliness of the production environment. Due to its high-efficiency transport performance, belt conveyor systems have been widely used in automated manufacturing, especially in semiconductor automation equipment, becoming an important component of material handling.

[0003] However, existing belt conveyor systems have significant drawbacks. As the belt moves continuously for extended periods, it inevitably rubs against related components, resulting in wear and tear. This wear generates a large amount of dust. In fields with extremely high cleanroom requirements, such as semiconductor manufacturing, this dust not only fails to meet the stringent standards of cleanroom environments but also directly affects product quality, leading to product defects, reduced yield, and significant economic losses and quality risks for manufacturers.

[0034] Addressing the problem that existing belt conveyor channels generate a large amount of dust, leading to product defects and reduced yield, this application provides a roller conveyor device that can provide a dust-free conveying environment.

[0035] refer to Figures 1-5The roller transmission device provided in this application embodiment includes: a first drive roller group 1 and a second drive roller group 2. The first roller group 12 includes a first upright plate 11, a first roller 12, a first transmission group 13, and a first drive element 14. The first roller 12 is located on a first side 111 of the first upright plate 11, and the first transmission group 13 and the first drive element 14 are located on a second side 112 of the first upright plate 11. The first side 111 and the second side 112 are disposed opposite to each other. The first drive element 14 drives the first roller 12 to rotate through the first transmission group 13. The first roller 12 is isolated from the first transmission group 13; the second drive roller group 2 includes a second upright plate 21, a second roller 22, a second transmission group 23, and a second drive element 24. The second roller 22 is located on the third side 212 of the second upright plate 21, and the second transmission group 23 and the second drive element 24 are located on the fourth side 212 of the second upright plate 21. The third side 212 and the fourth side 212 are separated from each other. The second drive element 24 drives the second roller 22 to rotate through the second transmission group 23. The second roller 22 is isolated from the second transmission group 23.

[0036] The first drive roller group 1 and the second drive roller group 2 are arranged at intervals. The rotation of the first roller 12 and the second roller 22 is used to transport the product. A flow channel 3 for transporting the product is formed between them. The second drive roller group 2 is configured to move closer to or further away from the first drive roller group 1 so that the size of the flow channel 3 can be adjusted to adapt to different transported products.

[0037] In this way, the first driving element 14 drives the first roller 12 to rotate through the first transmission group 13, and the second driving element 24 drives the second roller 22 to rotate through the second transmission group 23. The first driving roller group 1 and the second driving roller group 2 are spaced apart. The rotation of the first roller 12 and the second roller 22 drives the product to move along the flow channel 3 formed between them, realizing the product transfer. At the same time, the second driving roller group 2 can move closer to or further away from the first driving roller group 1, thereby flexibly adjusting the size of the flow channel 3 to meet the transfer requirements of products of different specifications. Moreover, the first roller 12 is isolated from the first transmission group 13, and the second roller 22 is isolated from the second transmission group 23, avoiding the influence of the transmission components on the roller transfer area. Based on this, compared to belts, rollers do not generate dust due to friction and wear during transmission. Furthermore, the isolation between the rollers and the transmission assembly further prevents impurities from the transmission components from contaminating the transmission environment, providing a dust-free environment for product transmission. This fundamentally solves the problem of product defects and reduced yield caused by dust in the belt transmission channel 3. The adjustable size of the channel 3 allows the roller transmission device to adapt to the transmission of various product specifications, greatly improving the device's versatility and applicability. This reduces the cost for companies to replace transmission equipment due to changes in product specifications, increases production efficiency, and enhances the company's competitiveness in the market.

[0038] Considering the transmission scheme of the roller transmission device for contacting the product, in the roller transmission device provided in the embodiments of this application, a first rubber ring 15 is sleeved on the outer periphery of the first roller 12, and a second rubber ring 25 is sleeved on the outer periphery of the second roller 22. The first rubber ring 15 is used to increase the friction between the first roller 12 and the transmitted product, and the second rubber ring 25 is used to increase the friction between the second roller 22 and the transmitted product.

[0039] Thus, during the operation of the roller conveyor, the first roller 12 contacts the conveyed product through the first rubber ring 15 fitted around its outer periphery, while the second roller 22 contacts the conveyed product through the second rubber ring 25 fitted around its outer periphery. The presence of the first and second rubber rings 15 increases the roughness of the roller and product surfaces, thereby enhancing the friction between the roller and the conveyed product. When the first drive element 14 drives the first roller 12 to rotate through the first transmission group 13, and the second drive element 24 drives the second roller 22 to rotate through the second transmission group 23, the increased friction allows for more stable and reliable product movement, achieving efficient product conveying within the flow channel 3.

[0040] Based on the above structural design, the first rubber ring 15 and the second rubber ring 25 can increase the friction between the roller and the conveyed product, effectively preventing slippage and deviation during the conveying process, ensuring the accuracy and stability of the product conveying path, and improving conveying precision. The stable conveying process reduces the risk of collisions and damage to the product caused by unstable conveying, which helps to improve product quality and yield. At the same time, reliable conveying also enables the roller conveying device to adapt to the conveying needs of products with more different materials and shapes, further enhancing the applicability and versatility of the device, reducing the maintenance and wear costs of enterprises in the product conveying process, and improving production efficiency and economic benefits.

[0041] Considering the transmission scheme of the first drive roller group 1, in the roller transmission device provided in the embodiments of this application, the first transmission group 13 includes a first synchronous belt pulley group 131 and a first magnetic wheel group 132. The first magnetic wheel group 132 includes a first magnetic driving wheel 1321 and a first magnetic driven wheel 1322. The first driving element 14 is used to drive the first synchronous belt pulley group 131 to rotate cyclically. The first output shaft 1311 of the first synchronous belt pulley group 131 is connected to the first magnetic driving wheel 1321 for transmission. The rotation of the first magnetic driving wheel 1321 is used to drive the rotation of the first magnetic driven wheel 1322. The first magnetic driving wheel 1321 is coaxially driven with the first roller 12 through the second output shaft 1323.

[0042] Thus, after the first driving element 14 is activated, it drives the first synchronous pulley group 131 to rotate cyclically. The first output shaft 1311 of the first synchronous pulley group 131 transmits power to the first magnetic drive wheel 1321, causing the first magnetic drive wheel 1321 to rotate. Based on the principle of magnetic transmission, the rotation of the first magnetic drive wheel 1321 drives the first magnetic driven wheel 1322, which it cooperates with, to rotate. The first magnetic drive wheel 1321 is coaxially driven with the first roller 12 through the second output shaft 1323, thereby ultimately transmitting power to the first roller 12, enabling the first roller 12 to rotate stably, and thus driving the conveyed product to move along the flow channel 3. In this process, the first synchronous pulley group 131 and the first magnetic wheel group 132 form a multi-stage transmission, realizing the effective transmission and conversion of power.

[0043] Furthermore, the first synchronous pulley set 131 is always located within the first drive pulley set. The first synchronous pulley set 131 does not contact the product, and the key method for transmitting power is magnetic drive. It does not need to directly contact the product or other transmission components, which reduces friction and wear between mechanical parts, reduces the possibility of dust and impurities being generated during transmission, and further maintains the cleanliness of the transmission environment, meeting the production requirements of a cleanroom environment. At the same time, this transmission method has a relatively simple structure and is easy to maintain, which can reduce equipment maintenance costs and downtime, improve equipment operating efficiency and service life, and enhance the practicality and economy of the roller transmission device in automated production.

[0044] Considering the specific arrangement of the first roller 12, multiple first rollers 12 are set, multiple first magnetic driven rollers 1322 are set, and multiple first magnetic driving rollers 1321 are set. One first roller 12 corresponds to one first magnetic driven roller 1322, and one first magnetic driven roller 1322 corresponds to one first magnetic driving roller 1321.

[0045] In this way, the one-to-one correspondence between multiple first rollers 12, first magnetic driven rollers 1322, and first magnetic driving rollers 1321 allows power to be distributed and evenly transmitted to each first roller 12. This avoids problems such as poor rotation and accelerated wear caused by excessive load on a single roller, improving the overall stability and reliability of the first roller group 12 and ensuring the smoothness of product transmission. This distributed power transmission method means that even if one roller or magnetic wheel fails, it will not seriously affect the normal operation of other rollers, reducing the overall failure rate of the equipment, minimizing downtime due to equipment failure, and improving production efficiency. At the same time, the coordinated work of multiple rollers can more effectively support and transmit products, adapting to the transmission needs of products of different weights and sizes, further enhancing the applicability and versatility of the roller transmission device, and providing strong support for diversified production in enterprises.

[0046] Considering the specific design of the dust cover in the first drive roller group 1, in the roller transmission device provided in this application embodiment, the first drive roller group 1 further includes a first dust cover 16. The first dust cover 16 is used to cover the first synchronous belt pulley group 131, the first drive element 14, each first magnetic driven wheel 1322, each first magnetic driving wheel 1321 and each first magnetic driven wheel 1322 on the second side 112 of the first vertical plate 11.

[0047] In this way, the first dust cover 16 covers the first synchronous pulley assembly 131, the first drive element 14, each first magnetic driven pulley 1322, each first magnetic drive pulley 1321, and each first magnetic driven pulley 1322 on the second side 112 of the first vertical plate 11, producing significant technical benefits. From a dust prevention perspective, this design effectively prevents dust, oil, and other impurities generated during the operation of the transmission components from entering the product transmission area, further ensuring the cleanliness of the working environment of the roller transmission device, avoiding quality problems caused by external impurities, and improving the product yield. From a component protection perspective, the dust cover provides a physical protective barrier for the internal transmission components, reducing the corrosion of components by external dust and moisture, reducing the wear rate and failure rate of components, extending the service life of each component of the first drive roller assembly 1, and thus reducing the maintenance and replacement costs of the equipment. In addition, dust covers can reduce the noise generated by transmission components during operation to a certain extent, optimize the working environment, and make the overall structure of the equipment more regular, which facilitates daily inspection, maintenance and management, improves the stability and reliability of equipment operation, and enhances the applicability and competitiveness of roller transmission devices in actual production.

[0048] Considering the transmission scheme of the second drive roller group 2, the second transmission group 23 includes a second synchronous belt pulley group 231 and a second magnetic wheel group 232. The second magnetic wheel group 232 includes a second magnetic driving wheel 2321 and a second magnetic driven wheel 2322. The second drive element 24 is used to drive the second synchronous belt pulley group 231 to rotate cyclically. The third output shaft 2311 of the second synchronous belt pulley group 231 is connected to the second magnetic driving wheel 2321. The rotation of the second magnetic driving wheel 2321 is used to drive the rotation of the second magnetic driven wheel 2322. The second magnetic driving wheel 2321 is coaxially driven with the second roller 22 through the fourth output shaft 2323.

[0049] In terms of transmission stability, the second drive element 24 drives the second synchronous pulley group 231 to rotate cyclically. Power is then transmitted to the second magnetic drive wheel 2321 via the third output shaft 2311. The second magnetic drive wheel 2321 then drives the second magnetic driven wheel 2322, and finally, the fourth output shaft 2323 causes the second roller 22 to rotate coaxially. This multi-stage transmission structure ensures smooth power transmission, preventing speed fluctuations in the second roller 22 due to unstable power. This maintains a uniform speed during transmission, improves transmission accuracy, and prevents collisions and deviations caused by speed changes. Regarding cleanliness, the non-contact nature of magnetic transmission reduces friction and wear between transmission components, minimizing dust and impurities. Combined with the overall dustproof design of the device, this further meets the requirements of a cleanroom environment, ensuring product integrity and improving product quality and yield. From the perspective of equipment maintenance and cost, this transmission scheme has a simple structure and high reliability, with little wear between components, which extends the service life of each component of the second drive roller group 2, reduces the frequency of equipment failure and maintenance costs; moreover, the second drive roller group 2 is similar to the transmission scheme of the first drive roller group 1, which facilitates unified maintenance management and spare parts inventory for enterprises, reduces operating costs, improves production efficiency, and enhances the competitiveness of the equipment in the market.

[0050] Considering the specific design of the second roller 22, in the roller transmission device provided in the embodiments of this application, multiple second rollers 22 are provided, multiple second magnetic driven rollers 2322 are provided, and multiple second magnetic driving rollers 2321 are provided. One second roller 22 corresponds to one second magnetic driven roller 2322, and one second magnetic driven roller 2322 corresponds to one second magnetic driving roller 2321.

[0051] From a power transmission perspective, the distributed transmission design allows power to be evenly distributed to each of the second rollers 22, preventing excessive load on individual rollers. This results in smoother and more reliable rotation of the entire group of second rollers 22, reducing transmission disruptions or roller damage caused by localized overloads, and ensuring the continuity and stability of product transmission. Even if one transmission component fails, it will not affect the normal operation of other rollers, greatly reducing the overall equipment failure rate, shortening downtime for maintenance, and effectively improving production efficiency. From a product transmission perspective, the coordinated operation of multiple second rollers 22 provides more uniform and stable support for the product, adapting to the transmission needs of products of different weights and sizes, enhancing the versatility and adaptability of the roller transmission device. Simultaneously, the uniform force distribution avoids deformation and damage caused by uneven localized force during transmission, contributing to improved product quality and yield. From an equipment maintenance and cost control perspective, this corresponding setup facilitates individual inspection, maintenance, and replacement of each transmission component, reducing maintenance difficulty and costs. Furthermore, the standardized design promotes mass production and inventory of parts, further reducing operating costs and improving economic efficiency.

[0052] Considering the dust cover scheme in the second drive roller group 2, in the roller transmission device provided in this application embodiment, the second drive roller group 2 further includes a second dust cover 26. The second dust cover 26 is used to cover the second synchronous belt pulley group 231, the second drive element 24, each second magnetic driven wheel 2322, each second magnetic driving wheel 2321 and each second magnetic driven wheel 2322 on the fourth side 212 of the second vertical plate 21.

[0053] In terms of environmental cleanliness, the second dust cover 26 completely encloses the transmission components such as the second synchronous pulley group 231 and the second drive element 24, effectively isolating them from dust, oil, debris, and other impurities generated during operation. This prevents them from entering the product transmission area. Combined with the dustproof design of the first drive roller group 1, this further ensures the entire transmission device remains in a dust-free and clean state, meeting the stringent environmental requirements of semiconductor manufacturing and other production scenarios. It eliminates quality problems caused by impurities at the source, significantly improving product yield. Regarding component protection, the second dust cover 26 constructs a physical protective barrier for the internal transmission components, blocking external dust, moisture, corrosive substances, and other harmful substances from eroding the components. This reduces wear and aging, lowers the probability of failure, and extends the service life of each component in the second drive roller group 2, thereby reducing equipment maintenance frequency and replacement costs. Meanwhile, the dust cover can also reduce the noise generated by the operation of transmission components to a certain extent, optimize the working environment, and make the equipment appearance more regular, which facilitates daily inspection, maintenance and management by staff, improves the stability and reliability of equipment operation, and enhances the applicability and market competitiveness of the roller transmission device in actual production.

[0054] Considering the scheme of adjustable bearing width of the transmission channel 3 between the two drive roller assemblies, the roller transmission device provided in this application embodiment also includes a sliding assembly 4 and a supporting base plate 5. The sliding assembly 4 includes a first track 41 and a first slider 42 slidably connected to the first track 41. The first track 41 is installed on the supporting base plate 5. The second drive roller assembly 2 also includes a first base plate 27. The first base plate 27 is connected to the bottom of the first upright plate 11. The first base plate 27 is used to support the first drive element 14. The first base plate 27 is installed on the first slider 42. The second drive roller assembly 2 moves with the first slider 42 through the first base plate 27.

[0055] In this way, by sliding the first slider 42 in the sliding assembly 4 on the first track 41, the second drive roller group 2 moves with the first base plate 27, allowing for convenient and precise adjustment of the distance between the first drive roller group 1 and the second drive roller group 2, thereby flexibly changing the load-bearing width of the transmission channel 3. This enables the roller transmission device to adapt to the transmission needs of products of different specifications and sizes. Whether it is small precision semiconductor components or large industrial parts, it can transmit stably, greatly improving the versatility and application range of the device and meeting the diverse production needs of enterprises. Furthermore, there is no need to replace the entire transmission equipment due to changes in product specifications, reducing equipment procurement costs and production line modification expenses. At the same time, the rapid adjustment of the width of the channel 3 reduces equipment adjustment time, improves production changeover efficiency, avoids production stoppages caused by equipment incompatibility, ensures continuous and efficient operation of the production line, and effectively improves the enterprise's production efficiency and economic benefits. In addition, this adjustable structure design is simple and easy to operate, facilitating daily equipment debugging and maintenance by staff, reducing the threshold for using the equipment and the difficulty of maintenance.

[0056] Considering the transmission scheme for relative movement between two drive roller groups, the roller transmission device provided in this application embodiment further includes a lead screw module 6. The lead screw module 6 includes an adjusting lead screw 61, an adjusting nut 62, a lead screw support 63, and an adjusting handle 64. The adjusting nut 62 is installed on the second vertical plate 21, and the lead screw support 63 is installed on the first vertical plate 11. The adjusting lead screw 61 passes through the lead screw support 63 and the adjusting nut 62 in sequence. The adjusting nut 62 is threadedly assembled with the adjusting lead screw 61. The adjusting handle 64 is used to drive the rotation of the adjusting lead screw 61.

[0057] In this way, by rotating the adjusting handle 64, the adjusting screw 61 is rotated. The adjusting nut 62, in conjunction with the threaded engagement of the adjusting screw 61, converts the rotational motion into linear motion, achieving precise displacement of the second drive roller group 2 relative to the first drive roller group 1. This transmission method can control the distance between the two drive roller groups with minimal adjustment, ensuring that the size of the transmission channel 3 can be finely adjusted according to product specifications. This meets the requirements of production scenarios with extremely high transmission accuracy, guaranteeing the accuracy and stability of the product's position during transmission. Simultaneously, the structural design of the screw module 6 allows operators to easily adjust the size of the channel 3 simply by rotating the adjusting handle 64, eliminating the need for complex tools and cumbersome operations, thus reducing operational difficulty and labor costs. The threaded transmission has excellent self-locking performance; once adjusted to the appropriate position, it can stably maintain the relative position of the two drive roller groups, preventing the channel 3 from shifting due to vibration, external forces, or other factors during transmission. This ensures the reliability and stability of the equipment operation and reduces product transmission failures and quality problems caused by positional changes.
