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

[0029] 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.

[0030] Figure 1 The diagram shown is a structural schematic of a sheet buffer device provided in 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 2 As 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 to support one end of a sheet carrier, which carries the sheet. The at least two sets of transmission assemblies 200 are respectively connected to the two parts of the buffer assembly 100. The drive assembly 300 includes a drive source 310 and at least two output shafts 3110 connected to the drive source 310. The at least two output shafts 3110 are respectively connected to the at least two sets of transmission assemblies 200 and configured to drive the at least two sets of transmission assemblies 200 to move, so that the at least two sets of transmission assemblies 200 simultaneously drive the buffer assembly 100 to move in the same direction.

[0031] 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.

[0032] For example, such as Figure 1 and Figure 2 As shown, there are two sets of transmission components 200 and two output shafts 3110. The two sets of transmission components 200 are respectively connected to two parts of the buffer component 100, and the two output shafts 3110 are respectively connected to the two sets of transmission components 200. The two output shafts 3110 drive the two sets of transmission components 200 to move, so that the two sets of transmission components 200 drive the buffer component 100 to move in the same direction. The sheet buffer device 10 realizes the transportation of the buffer component 100 by using as few transmission components 200 and output shafts 3110 as possible, thereby further reducing the space occupied by the sheet buffer device 10 and reducing the cost of the sheet buffer device 10.

[0033] For example, the sheet can be a silicon wafer, a solar panel, a glass substrate, etc.

[0034] In some embodiments, such as Figure 1 , Figures 3 to 5As shown, the transmission assembly 200 includes a support member 210, at least two transmission wheels 220, and a transmission belt 230. The support member 210 extends along a first direction X1, which is the direction of movement of the buffer assembly 100. The at least two transmission wheels 220 are rotatably connected to the two ends of the support member 210 that are opposite to each other in the first direction X1. The at least two transmission wheels 220 include a drive wheel 221, and at least two output shafts 3110 are respectively connected to the drive wheels 221 included in each of the at least two sets of transmission assemblies 200. The axis of the drive wheel 221 is perpendicular to the first direction X1. The transmission belt 230 is sleeved on the at least two transmission wheels 220 and connected to the corresponding part of the buffer assembly 100. Driven by the transmission wheels 220, the belt moves around the at least two transmission wheels 220 to drive the buffer assembly 100 to move along the first direction X1.

[0035] The transmission assembly 200 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.

[0036] For example, such as Figure 3 and Figure 4 As shown, the transmission assembly 200 includes two transmission wheels 220, namely a driving wheel 221 and a driven wheel 222. The driving wheel 221 and the driven wheel 222 are rotatably connected to the two ends of the support member 210 that are opposite to each other in the first direction X1. The transmission belt 230 is sleeved on the driving wheel 221 and the driven wheel 222, and moves around the driving wheel 221 and the driven wheel 222 under the drive of the driving wheel 221 and the driven wheel 222, so as to drive the buffer assembly 100 to move along the first direction X1.

[0037] In some embodiments, such as Figure 5 As shown, the transmission assembly 200 also includes a slide rail 240 and a slider 250. The slide rail 240 extends along a first direction X1, and the slider 250 is slidably connected to the slide rail 240 and connected to a corresponding part of the buffer assembly 100.

[0038] By using the slide rail 240 and the slider 250 to guide the movement of the buffer component 100, the movement accuracy of the buffer component 100 is improved.

[0039] In addition, the buffer assembly 100 is supported by the slide rail 240 and the slider 250 to share the load on the drive belt 230.

[0040] In some embodiments, such as Figure 3 and Figure 4As shown, the support member 210 includes a support body 2110 and at least two support portions 2120. The support body 2110 extends along a first direction X1, and at least two support portions 2120 are disposed on the upper surface of the support body 2110, and are respectively disposed at two opposite ends of the support body 2110 in the first direction X1. The support portion 2120 includes a first support portion 2121 and a second support portion 2122 disposed opposite to each other along the extending direction of the axis of the transmission wheel 220. The transmission wheel 220 is disposed between the first support portion 2121 and the second support portion 2122, and both ends of the transmission wheel 220 are rotatably connected to the first support portion 2121 and the second support portion 2122, respectively.

[0041] The support component 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.

[0042] For example, there are two support portions 2120, which are disposed on the upper surface of the support body 2110 and respectively disposed at opposite ends of the support body 2110 in the first direction X1.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the drive source 310 and the support member 210 are fixedly arranged relative to each other. The drive assembly 300 also includes at least two transmission rods 320, which are respectively connected to at least two output shafts 3110 and respectively connected to the drive wheels 221 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.

[0044] 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.

[0045] 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 included in each of the two sets of transmission components 200, so as to realize the two transmission rods 320 respectively drive the two sets of transmission components 200 to move.

[0046] For example, such as Figure 2 As shown, 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.

[0047] In some embodiments, such as Figure 3 As shown, the drive assembly 300 also includes a coupling 330, which is disposed between the transmission rod 320 and the drive wheel 221. The two ends of the coupling 330 in the axial direction of the drive wheel 221 are respectively connected to the transmission rod 320 and the drive wheel 221.

[0048] 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.

[0049] In some embodiments, the buffer assembly 100 includes at least two sub-buffer assemblies 110, which are disposed 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 transmission assembly 200, 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.

[0050] 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.

[0051] For example, such as Figure 1 As shown, the buffer assembly 100 includes two sub-buffer assemblies 110, which are arranged opposite each other along a second direction X2. Each sub-buffer assembly 110 is connected to two sets of transmission assemblies 200, so that the two sets of transmission assemblies 200 drive the two sub-buffer assemblies 110 to move along a 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.

[0052] For example, such as Figure 5 As 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.

[0053] For example, such as Figure 1 , Figures 3 to 5 As shown, the buffer support 1110 is connected to the transmission belt 230, which enables the transmission belt 230 to drive the sub-buffer assembly 110 to move along the first direction X1 when the transmission belt 230 moves around the driving wheel 221 and the driven wheel 222.

[0054] For example, the buffer support 1110 is detachably connected to the drive belt 230 to facilitate replacement or maintenance of the drive belt 230 and the sub-buffer assembly 110.

[0055] For example, such as Figure 5 As shown, the buffer support 1110 is connected to the slider 250, and the slider 250 is slidably connected to the slide rail 240 so that the slide rail 240 and the slider 250 support the sub-buffer assembly 110 and guide the movement of the sub-buffer assembly 110.

[0056] In some embodiments, such as Figures 5 to 7 As shown, the sub-buffer assembly 110 further includes a first connector 1130 and a second connector 1140. The first connector 1130 is connected to the buffer support 1110, and the second connector 1140 is detachably connected to the first connector 1130. The first connector 1130 and the second connector 1140 respectively contact two opposite surfaces of the drive belt 230, so that the first connector 1130 and the second connector 1140 clamp the drive belt 230.

[0057] The transmission belt 230 is clamped by the first connector 1130 and the second connector 1140, thereby connecting the sub-buffer assembly 110 and the transmission assembly 200. In addition, the second connector 1140 is detachably connected to the first connector 1130, which facilitates the installation and removal of the buffer assembly 100 and the transmission assembly 200.

[0058] In some embodiments, such as Figure 6 As shown, the side of the first connector 1130 near the second connector 1140 includes a first concave-convex structure 1131.

[0059] In some embodiments, the side of the second connector 1140 near the first connector 1130 includes a second convex-concave structure.

[0060] In some embodiments, the side of the first connector 1130 near the second connector 1140 includes a first convex-concave structure 1131, and the side of the second connector 1140 near the first connector 1130 includes a second convex-concave structure.

[0061] The use of concave and convex structures increases the friction between the connector and the transmission belt 230, thereby improving the stability of the connection between the connector and the transmission belt 230.

[0062] In some embodiments, such as Figure 7 As shown, the sub-buffer assembly 110 also includes a positioning roller 1150, which is rotatably connected to the buffer support 1110. The axis of the positioning roller 1150 is parallel to the first direction X1, and the vertical height of the top of the positioning roller 1150 is greater than the vertical height of the top of the support wheel 1120.

[0063] The sheet carrier typically falls from above the buffer assembly 100 onto the support roller 1120, and the positioning roller 1150 can appropriately adjust the positional error of the sheet carrier before it is placed on the support roller 1120.

[0064] In some embodiments, such as Figure 8 and Figure 9 As shown, the sheet buffer device 10 also includes a protective component 400. The protective component 400 is connected to the buffer component 100 and is configured to receive and hold the broken sheet in the event that the sheet carried by the buffer component 100 breaks.

[0065] For example, the protective assembly 400 extends along a second direction X2 and includes a first support frame 410 and a plurality of protective plates 420. The first support frame 410 extends along the second direction X2, and its two ends are respectively connected to the buffer supports 1110 of two sub-buffer assemblies 110 of the buffer assembly 100. The plurality of protective plates 420 are arranged sequentially along the first direction X1 and the second direction X2, and are all connected to the first support frame 410. The protective assembly 400 has a simple structure and low cost.

[0066] For example, the first support frame 410 is assembled from multiple profiles.

[0067] In some embodiments, such as Figure 8 and Figure 9 As shown, the sheet buffer device 10 also includes a heat insulation component 500, which is connected to the buffer component 100 and configured to isolate the buffer component 100 from the process furnace.

[0068] The heat insulation component 500 isolates the buffer component 100 from the process furnace, reducing the heat transfer from the process furnace to the sheet carrier and sheet carried by the buffer component 100. In addition, it can also prevent impurities in the process furnace from falling onto the buffer component 100 and the sheet carrier and sheet carried by the buffer component 100.

[0069] For example, the thermal insulation assembly 500 extends along a second direction X2 and includes a second support frame 510 and a plurality of thermal insulation panels 520. The second support frame 510 extends along the second direction X2 and is connected to a first support frame 410. The vertical height of the top of the thermal insulation assembly 500 is greater than the vertical height of the top of the buffer assembly 100.

Figure 10 As shown, the sheet buffer system 1 includes at least one sheet buffer device 10 mentioned in the above embodiments and a frame 20, with the sheet buffer device 10 connected to the frame 20. When the sheet buffer system 1 includes multiple sheet buffer devices 10, the multiple sheet buffer devices 10 are arranged at intervals in the vertical direction, or the multiple sheet buffer devices 10 are arranged sequentially in the horizontal direction, or the multiple sheet buffer devices 10 are arranged at intervals in the vertical direction and sequentially in the horizontal direction.
