Description

Technical Field

[0001] This disclosure relates to the fields of semiconductor and photovoltaic technology, and in particular to a sheet buffer device and a sheet buffer system. Background Technology

[0002] Semiconductor or photovoltaic equipment typically processes products in a high-temperature environment. After the process is completed, the product is usually at a high temperature when it leaves the equipment. Therefore, it is usually necessary to place the product on a buffer device and wait for it to cool down before transferring it to the next process.

[0003] However, the buffer device in the related technology is stationary. Therefore, an additional transportation device is required to transport the products buffered by the buffer device to the next process. Furthermore, a connection structure is required between the transportation device and the buffer device to transfer the products buffered by the buffer device to the transportation device. This results in the buffer device occupying a large space and incurring high costs. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0032] Figure 1 The diagram shown is a schematic representation of a sheet buffer device in its working state according to an embodiment of this disclosure. Figure 2 As shown Figure 1 The image shows a magnified view of a portion of area A of the sheet buffer device. (See image.) Figure 1 and Figure 2As shown, the sheet buffer device 10 includes a buffer assembly 100, at least two sets of transmission assemblies 200, and a drive assembly 300. The buffer assembly 100 includes two opposing parts, each serving as a support for one end of a sheet carrier configured to carry a sheet. At least two sets of transmission assemblies 200 are connected to the two parts of the buffer assembly 100, and the drive assembly 300 is connected to both sets of transmission assemblies 200 and configured to drive the two parts of the buffer assembly 100 to move along a first direction X1 via the at least two sets of transmission assemblies 200. The transmission assembly 200 includes multiple stages of sub-transmission assemblies 210 connected sequentially, with each stage 210 configured to drive the next stage 210 to move along the first direction X1. The first stage sub-transmission assembly 210 is connected to the drive assembly 300, and the last stage sub-transmission assembly 210 is connected to the corresponding part of the buffer assembly 100.

[0033] In related technologies, buffer devices are typically fixed and require additional transport devices to move the buffered products to the next process. Furthermore, a connection structure is needed between the transport device and the buffer device to transfer the buffered products to the transport device, resulting in a large space requirement and high cost for the buffer device. The sheet buffer device 10 utilizes a buffer assembly 100 to buffer the sheet carrier and the sheet, and uses a drive assembly 300 and a transmission assembly 200 to replace the transport device in related technologies, achieving the transport of the buffer assembly 100, the sheet carrier, and the sheet. Moreover, it eliminates the need for an additional connection structure between the buffer assembly 100 and the transmission assembly 200, thus reducing the space required and cost of the sheet buffer device 10.

[0034] For example, such as Figure 1 As shown, there are two sets of transmission components 200. Each set of transmission components 200 is connected to one of the two parts of the buffer component 100. The drive component 300 drives the two parts of the buffer component 100 to move along the first direction X1 via the two sets of transmission components 200. The sheet buffer device 10 utilizes as few transmission components 200 as possible to transport the buffer component 100, thereby further reducing the space occupied by the sheet buffer device 10 and lowering its cost.

[0035] The number of sub-transmission assemblies 210 in the transmission assembly 200 can be set according to actual needs. For example, such as... Figure 2As shown, the transmission assembly 200 has two levels of sub-transmission assemblies 210. The first-level sub-transmission assembly 210 is connected to the drive assembly 300, and the second-level sub-transmission assembly 210 is connected to the first-level sub-transmission assembly 210. The first-level sub-transmission assembly 210 drives the second-level sub-transmission assembly 210 to move along the first direction X1. The buffer assembly 100 is connected to the second-level sub-transmission assembly 210, and the second-level sub-transmission assembly 210 drives the buffer assembly 100 to move along the first direction X1. The sheet buffer device 10 can simultaneously enable the first-level sub-transmission assembly 210 to drive the second-level sub-transmission assembly 210 to move along the first direction X1, while the second-level sub-transmission assembly 210 drives the buffer assembly 100 to move in the same direction along the first direction X1. This allows the sheet buffer device 10 to move a large distance along the first direction X1 when it is in operation, and allows the multi-level sub-transmission assemblies 210 and the buffer assembly 100 to return to their original positions along the first direction X1 when the sheet buffer device 10 is not in operation, thus minimizing the space occupied by the sheet buffer device 10. Figure 4 The diagram shown is a structural schematic of a sheet buffer device in a non-operating state according to an embodiment of this disclosure. Figure 1 and Figure 4 As shown, when the sheet buffer device 10 is not in operation, the multi-stage sub-drive assembly 210 and the buffer assembly 100 are stacked in the vertical direction. When the sheet buffer device 10 is in operation, the multi-stage sub-drive assembly 210 and the buffer assembly 100 are arranged in the first direction X1.

[0036] For example, the sheet can be a silicon wafer, a solar panel, a glass substrate, etc.

[0037] In some embodiments, such as Figures 5 to 8 As shown, the sub-drive assembly 210 includes a support member 2110, at least two drive wheels 2120, and a drive belt 2130. The support member 2110 extends along a first direction X1, and the at least two drive wheels 2120 are rotatably connected to the two ends of the support member 2110 that are opposite to each other in the first direction X1. Each of the at least two drive wheels 2120 includes a drive wheel 2121, and the drive assembly 300 is drively connected to the drive wheel 2121. The axis of the drive wheel 2121 is perpendicular to the first direction X1. The drive belt 2130 is sleeved on the at least two drive wheels 2120 and moves around the at least two drive wheels 2120 under their drive. The drive belt 2130 of the previous sub-drive assembly 210 is connected to the support member 2110 of the next sub-drive assembly 210, and the drive belt 2130 of the last sub-drive assembly 210 is connected to the end of the buffer assembly 100.

[0038] The sub-drive assembly 210 has a simple structure and low cost, which further reduces the space occupied by the sheet buffer device 10 and lowers the cost of the sheet buffer device 10.

[0039] Specifically, since the transmission belt 2130 of the upper-level sub-transmission assembly 210 is connected to the support member 2110 of the lower-level sub-transmission assembly 210, the movement of the transmission belt 2130 of the upper-level sub-transmission assembly 210 can drive the lower-level sub-transmission assembly 210 to move along the first direction X1. Since the transmission belt 2130 of the last-level sub-transmission assembly 210 is connected to the end of the buffer assembly 100, the movement of the transmission belt 2130 of the last-level sub-transmission assembly 210 can drive the end of the buffer assembly 100 to move in the same direction as the sub-transmission assembly 210 along the first direction X1.

[0040] For example, such as Figures 6 to 8 As shown, the sub-transmission assembly 210 includes two transmission wheels 2120, each consisting of a driving wheel 2121 and a driven wheel 2122. The driving wheel 2121 and the driven wheel 2122 are rotatably connected to the two ends of the support member 2110 that are opposite each other in the first direction X1. A transmission belt 2130 is sleeved on the driving wheel 2121 and the driven wheel 2122, and moves around the driving wheel 2121 and the driven wheel 2122 under their drive. The drive assembly 300 is connected to the driving wheel 2121 of the first-stage sub-transmission assembly 210. The support member 2110 of the second-stage sub-transmission assembly 210 is connected to the transmission belt 2130 of the first-stage sub-transmission assembly 210, thereby enabling the first-stage sub-transmission assembly 210 to move along the first direction X1 when the drive assembly 300 drives the transmission belt 2130 of the first-stage sub-transmission assembly 210. The transmission belt 2130 of the second-stage sub-transmission assembly 210 is also connected to the support member 2110 of the first-stage sub-transmission assembly 210, enabling the second-stage sub-transmission assembly 210 to move around the two transmission wheels 2120 of the second-stage sub-transmission assembly 210 when the second-stage sub-transmission assembly 210 moves along the first direction X1. The end of the buffer component 100 is connected to the drive belt 2130 of the second-stage sub-drive component 210, so that when the drive belt 2130 of the second-stage sub-drive component 210 moves, it drives the end of the buffer component 100 to move in the same direction as the second-stage sub-drive component 210 along the first direction X1.

[0041] For example, such as Figure 6As shown, the support member 2110 of the second-stage sub-drive assembly 210 is connected to the side of the drive belt 2130 of the first-stage sub-drive assembly 210 that is close to the second-stage sub-drive assembly 210. The side of the drive belt 2130 of the second-stage sub-drive assembly 210 that is close to the first-stage sub-drive assembly 210 is connected to the support member 2110 of the first-stage sub-drive assembly 210. The side of the drive belt 2130 of the second-stage sub-drive assembly 210 that is away from the first-stage sub-drive assembly 210 is connected to the end of the buffer assembly 100. This is to ensure that when the second-stage sub-drive assembly 210 moves along the first direction X1, the end of the buffer assembly 100 moves in the same direction as the second-stage sub-drive assembly 210 along the first direction X1.

[0042] In some embodiments, such as Figure 3 and Figure 6 As shown, the sub-drive assembly 210 also includes a slide rail 2140 and a slider 2150. The slide rail 2140 extends along a first direction X1, and the slider 2150 is slidably connected to the slide rail 2140. The slider 2150 of the previous sub-drive assembly 210 is connected to the support member 2110 of the next sub-drive assembly 210, and the slider 2150 of the last sub-drive assembly 210 is connected to the end of the buffer assembly 100.

[0043] By utilizing the slide rail 2140 and slider 2150 of the upper-level sub-transmission assembly 210 to guide the movement of the lower-level sub-transmission assembly 210, the movement accuracy of the lower-level sub-transmission assembly 210 is improved. In addition, the slide rail 2140 and slider 2150 of the upper-level sub-transmission assembly 210 can support the lower-level sub-transmission assembly 210, sharing the load on the transmission belt 2130 of the upper-level sub-transmission assembly 210.

[0044] Furthermore, the slide rail 2140 and slider 2150 of the last-stage sub-drive assembly 210 guide the movement of the buffer assembly 100, improving the movement accuracy of the buffer assembly 100. Additionally, the slide rail 2140 and slider 2150 of the last-stage sub-drive assembly 210 support the buffer assembly 100, sharing the load on the drive belt 2130 of the last-stage sub-drive assembly 210.

[0045] For example, the slide rail 2140 and slider 2150 of the first-stage sub-drive assembly 210 provide support and motion guidance for the second-stage sub-drive assembly 210. The slide rail 2140 and slider 2150 of the second-stage sub-drive assembly 210 provide support and motion guidance for the buffer assembly 100.

[0046] In some embodiments, such as Figure 7 and Figure 8As shown, the support member 2110 includes a support body 2111 and at least two support portions 2112. The support body 2111 extends along a first direction X1, and at least two support portions 2112 are disposed on the upper surface of the support body 2111, and are respectively disposed at two opposite ends of the support body 2111 in the first direction X1. The support portion 2112 includes a first support portion 2212 and a second support portion 2312 disposed opposite to each other along the extending direction of the axis of the transmission wheel 2120. The transmission wheel 2120 is disposed between the first support portion 2212 and the second support portion 2312, and both ends of the transmission wheel 2120 are rotatably connected to the first support portion 2212 and the second support portion 2312, respectively.

[0047] The support member 2110 has a simple structure and can stably support the transmission wheel 2120.

[0048] For example, the support member 2110 includes two support portions 2112, which respectively support the driving wheel 2121 and the driven wheel 2122.

[0049] In some embodiments, such as Figure 6 , Figure 7 and Figure 9 As shown, the drive assembly 300 includes a drive source 310 and at least two transmission rods 320. The drive source 310 is fixedly disposed relative to the support member 2110, and the drive source 310 includes at least two output shafts 3110. The at least two transmission rods 320 are respectively connected to the at least two output shafts 3110, and respectively connected to the drive wheel 2121 in the first-stage sub-drive assembly 210 included in each of the at least two sets of transmission assemblies 200. The geometric axis of the transmission rod 320 along its extension direction is collinear with the axis of the output shaft 3110.

[0050] The drive component 300 has a simple structure and low cost, which further reduces the space occupied by the sheet buffer device 10 and lowers the cost of the sheet buffer device 10.

[0051] For example, there are two transmission rods 320. The two transmission rods 320 are respectively connected to two output shafts 3110 and respectively connected to the drive wheel 221 in the first stage sub-transmission assembly 210 included in each of the two sets of transmission assemblies 200, thereby realizing the use of two transmission rods 320 to drive the two sets of transmission assemblies 200 to move.

[0052] For example, the drive source 310 includes a motor 3101 and a reducer 3102. The output shaft of the motor 3101 is connected to the reducer 3102, and the reducer 3102 includes two output shafts 3110. The drive source 310 has a simple structure and low cost, thereby further reducing the space occupied by the drive assembly 300 and lowering the cost of the drive assembly 300.

[0053] In some embodiments, such as Figure 6 and Figure 7 As shown, the drive assembly 300 also includes a coupling 330, which is disposed between the transmission rod 320 and the drive wheel 2121 included in the first-stage sub-transmission assembly 210. The two ends of the coupling 330 in the axial direction of the drive wheel 2121 included in the first-stage sub-transmission assembly 210 are respectively connected to the transmission rod 320 and the drive wheel 2121 included in the first-stage sub-transmission assembly 210.

[0054] Due to manufacturing or installation errors, the transmission rod 320 may experience shaft misalignment during transmission. By setting up a coupling 330, shaft misalignment can be compensated, reducing jamming and component damage during transmission.

[0055] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 10 As shown, the buffer assembly 100 includes at least two sub-buffer assemblies 110, which are arranged opposite to each other along a second direction X2 and are respectively used to support both ends of the sheet carrier. Each sub-buffer assembly 110 includes a buffer support 1110 and a support wheel 1120. The buffer support 1110 is connected to the last-stage sub-drive assembly 210, and the support wheel 1120 is rotatably connected to the buffer support 1110. The axis of the support wheel 1120 is parallel to the second direction X2, and the upper surface of the support wheel 1120 is configured to contact the sheet carrier to buffer the sheet carrier and the sheet carried by it.

[0056] By having the upper surface of the support wheel 1120 contact the sheet carrier, line contact between the support wheel 1120 and the sheet carrier is achieved, reducing the contact area between the buffer assembly 100 and the sheet carrier, thereby reducing the contamination of the sheet carrier by the buffer assembly 100.

[0057] For example, such as Figure 1 , Figure 2 and Figure 4 As shown, the buffer assembly 100 includes two sub-buffer assemblies 110, which are arranged opposite each other along the second direction X2. Each sub-buffer assembly 110 is connected to the last stage sub-drive assembly 210 of each of the two sets of drive assemblies 200, so that the two sets of drive assemblies 200 respectively drive the two sub-buffer assemblies 110 to move along the first direction X1. By using the two sub-buffer assemblies 110 to support both ends of the sheet carrier, the contact area between the buffer assembly 100 and the sheet carrier is further reduced, thereby further reducing contamination of the sheet carrier by the buffer assembly 100.

[0058] For example, such as Figure 2 and Figure 10As shown, the buffer support 1110 extends along the first direction X1, and there are two support wheels 1120. The two support wheels 1120 are disposed at both ends of the buffer support 1110 in the first direction X1 to support the same end of the sheet carrier. By using the two support wheels 1120 to support the same end of the sheet carrier, the stability of the buffer assembly 100 in supporting the sheet carrier is improved, while minimizing the contact area between the buffer assembly 100 and the sheet carrier.

[0059] For example, the buffer support 1110 is connected to the side of the drive belt 2130 of the second-stage sub-drive assembly 210 away from the first-stage sub-drive assembly 210.

[0060] For example, such as Figure 2 As shown, the buffer support 1110 is connected to the slider 2150 of the second-stage sub-transmission assembly 210. The slider 2150 of the second-stage sub-transmission assembly 210 is slidably connected to the slide rail 2140 of the second-stage sub-transmission assembly 210, so that the slide rail 2140 and the slider 2150 of the second-stage sub-transmission assembly 210 support the sub-buffer assembly 110 and guide the movement of the sub-buffer assembly 110.

[0061] In some embodiments, such as Figure 7 and Figure 10 As shown, the sheet buffer device 10 also includes a plurality of connecting components 400, which are connected between adjacent sub-drive components 210 or between the last sub-drive component 210 and the buffer support 1110. Each connecting component 400 includes a first connector 410 and a second connector 420. The first connector 410 located between adjacent sub-drive components 210 is connected to the support 2110 of the next-level sub-drive component 210; the first connector 410 located between the last-level sub-drive component 210 and the buffer support 1110 is connected to the buffer support 1110; and the second connector 420 is detachably connected to the first connector 410. The first connector 410 and the second connector 420 located between adjacent sub-drive components 210 respectively contact the opposite surfaces of the drive belt 2130 of the previous-level sub-drive component 210 to clamp the drive belt 2130 of the previous-level sub-drive component 210.

[0062] The first and second connectors 410 and 420 are detachably connected to connect the support 2110 and drive belt 2130 of adjacent-level sub-drive assemblies 210, facilitating the installation and removal of adjacent-level sub-drive assemblies 210, thereby facilitating the installation and removal of drive assembly 200. Furthermore, the first and second connectors 410 and 420 are detachably connected to connect the drive belt 2130 of the last-level sub-drive assembly 210 to the buffer support 1110 of the sub-buffer assembly 110, facilitating the installation and removal of the sub-buffer assembly 110, thereby facilitating the installation and removal of buffer assembly 100.

[0063] For example, one connecting component 400 connects the side of the drive belt 2130 of the first-stage drive assembly 210 near the second-stage drive assembly 210 to the support member 2110 of the second-stage sub-drive assembly 210. Another connecting component 400 connects the side of the drive belt 2130 of the second-stage sub-drive assembly 210 away from the first-stage drive assembly 210 to the buffer support member 1110 of the sub-buffer assembly 110.

[0064] For example, such as Figure 8 As shown, the sheet buffer device 10 also includes a mounting component 700. The mounting component 700 connects the side of the transmission belt 2130 of the second-stage sub-transmission component 210 near the first-stage transmission component 210 to the support member 2110 of the first-stage transmission component 210, so that when the second-stage sub-transmission component 210 moves along the first direction X1, the transmission belt 2130 of the second-stage sub-transmission component 210 moves, thereby driving the sub-buffer component 110 to move in the same direction as the second-stage sub-transmission component 210 along the first direction X1.

[0065] In some embodiments, the side of the first connector 410 near the second connector 420 includes a first convex-concave structure 4101.

[0066] In some embodiments, the side of the second connector 420 near the first connector 410 includes a second convex-concave structure.

[0067] In some embodiments, the side of the first connector 410 near the second connector 420 includes a first convex-concave structure 1131, and the side of the second connector 420 near the first connector 410 includes a second convex-concave structure.

[0068] The use of concave and convex structures increases the friction between the connector and the transmission belt 2130, thereby improving the stability of the connection between the connector and the transmission belt 2130.

[0069] In some embodiments, such as Figure 10As shown, the sub-buffer assembly 110 also includes a positioning roller 1130, which is rotatably connected to the buffer support 1110. The axis of the positioning roller 1130 is parallel to the first direction X1, and the vertical height of the top of the positioning roller 1130 is greater than the vertical height of the top of the support wheel 1120.

[0070] The sheet carrier typically falls from above the buffer assembly 100 onto the support roller 1120, and the positioning roller 1130 can appropriately adjust the positional error of the sheet carrier before it is placed on the support roller 1120.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, the sheet buffer device 10 also includes a protective component 500. The protective component 500 is connected to the buffer component 100 and is configured to receive and carry the broken sheet in the event of sheet breakage on the sheet carrier carried by the buffer component 100.

[0072] For example, such as Figure 1 and Figure 2 As shown, the protective assembly 500 extends along the second direction X2 and includes a first support frame 510 and multiple protective plates 520. The first support frame 510 extends along the second direction X2, and its two ends are respectively connected to the buffer supports 1110 of the two sub-buffer assemblies 110 of the buffer assembly 100. The multiple protective plates 520 are arranged sequentially along the first direction X1 and the second direction X2, and are all connected to the first support frame 510. The protective assembly 500 has a simple structure and low cost.

[0073] For example, the first support frame 510 is assembled from multiple profiles.

[0074] In some embodiments, such as Figure 1 As shown, the sheet buffer device 10 also includes a heat insulation component 600, which is connected to the buffer component 100 and configured to isolate the buffer component 100 from the process furnace.

[0075] The heat insulation component 600 isolates the buffer component 100 from the process furnace, reducing the heat transfer from the process furnace to the sheet carrier carried by the buffer component 100 and the sheet carried by the sheet carrier. In addition, it can also prevent impurities in the process furnace from falling onto the buffer component 100, the sheet carrier carried by the buffer component 100, and the sheet carried by the sheet carrier.

[0076] For example, such as Figure 1As shown, the thermal insulation assembly 600 extends along a second direction X2 and includes a second support frame 610 and a plurality of thermal insulation panels 620. The second support frame 610 extends along the second direction X2 and is connected to a first support frame 510. The plurality of thermal insulation panels 620 are arranged sequentially along the second direction X2 and are all connected to the second support frame 610. The vertical height of the top of the thermal insulation assembly 600 is greater than the vertical height of the top of the buffer assembly 100.

[0077] For example, the second support frame 610 is assembled from multiple profiles.
