DETAILED DESCRIPTION

[0042] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0043] For examples, see Figure 1 At least one embodiment provides a carrier circulating conveying device, including: a carrier conveying mechanism 100, a silicon wafer conveying mechanism 200, a loading mechanism 300 and a processing mechanism 400; the carrier conveying mechanism 100 is suitable for circulating the carrier 110; the silicon wafer conveying mechanism 200 is arranged at the feed port of the carrier conveying mechanism 100, and is suitable for conveying silicon wafers; the loading mechanism 300 is arranged above the carrier conveying mechanism 100 and the silicon wafer conveying mechanism 200, and is suitable for grabbing the silicon wafers conveyed by the silicon wafer conveying mechanism 200 and placing them on the carrier 110 conveyed by the carrier conveying mechanism 100; the processing mechanism 400 is arranged at the discharge port of the carrier conveying mechanism 100, and is suitable for processing the silicon wafers on the carrier 110. By setting up a carrier conveying mechanism 100, silicon wafers are conveyed in batches. During processing, the carrier 110 is conveyed to the processing mechanism 400, and the silicon wafers on the carrier 110 are processed in batches. After the processing is completed, the carrier 110 is taken out of the processing mechanism 400, and the next carrier 110 is conveyed to the processing mechanism 400, thereby reducing the time for loading silicon wafers and improving the processing efficiency of the processing mechanism 400. At the same time, the empty carrier 110 is placed in the carrier conveying mechanism 100 to complete the circulation of the carrier 110, reducing the number of carriers 110 used, and thereby reducing the cost of the overall production line.

[0044] See also Figure 2In some embodiments, the carrier conveying mechanism 100 includes: a first conveyor line 120, a second conveyor line 130 and a lifting assembly 140; the first conveyor line 120 and the second conveyor line 130 are stacked; the first conveyor line 120 is arranged above the second conveyor line 130; the conveying direction of the first conveyor line 120 is from the silicon wafer conveying mechanism 200 to the processing mechanism 400, and is suitable for conveying carriers 110 loaded with silicon wafers; the conveying direction of the second conveyor line 130 is from the processing mechanism 400 to the silicon wafer conveying mechanism 200, and is suitable for conveying empty carriers 110; the lifting assembly 140 is suitable for conveying the empty carriers 110 conveyed in the second conveyor line 130 to the first conveyor line 120. By dividing the carrier conveyor mechanism 100 into a first conveyor line 120 and a second conveyor line 130, empty carriers 110 placed on the carrier conveyor mechanism 100 are prevented from interfering with carriers 110 currently being loaded with silicon wafers. Furthermore, stacking the first and second conveyor lines 120, 130 reduces the space occupied by the carrier conveyor mechanism 100, making the carrier conveyor mechanism 100 more compact. A lifting assembly 140 is provided to transport empty carriers 110 from the second conveyor line 130 to the first conveyor line 120, completing the loading of carriers 110 and facilitating subsequent loading of silicon wafers.

[0045] Please continue reading Figure 2 The specific structure of the lifting assembly 140 is described below. In a preferred embodiment, the lifting assembly 140 includes a lifting frame 141 and a transfer conveyor belt 142. The transfer conveyor belt 142 is mounted on the lifting frame 141. The lifting frame 141 is adapted to raise and lower the transfer conveyor belt 142, thereby transporting the empty carriers 110 from the second conveyor line 130 to the first conveyor line 120. Specifically, the lifting frame 141 is positioned below the wafer conveying mechanism 200. By raising and lowering the entire transfer conveyor belt 142 and controlling its conveying direction, the carriers 110 are circulated.

[0046] Please continue reading Figure 2The structures of the first conveyor line 120 and the second conveyor line 130 are described in detail below. In a preferred embodiment, the first conveyor line 120 includes a first conveyor section 121 and a second conveyor section 122; the first conveyor section 121 and the second conveyor section 122 are spaced apart. Empty carriers 110 are loaded with silicon wafers on the first conveyor section 121. After loading, the carriers 110 are transported to the second conveyor section 122 for placement, awaiting processing by the processing mechanism 400. This saves the processing mechanism 400 the time it spends waiting for the carriers 110 to be loaded, thereby improving the overall efficiency of the processing mechanism 400.

[0047] Correspondingly, the second conveyor line 130 includes a third conveyor section 131 and a fourth conveyor section 132; the third conveyor section 131 and the fourth conveyor section 132 are spaced apart. The positions of the third conveyor section 131 and the fourth conveyor section 132 correspond to the first conveyor section 121 and the second conveyor section 122. Empty carriers 110 are loaded on the fourth conveyor section 132 and transported to the third conveyor section 131 for placement, awaiting lifting and transfer by the lifting assembly 140.

[0048] See also Figure 3 In some embodiments, the carrier 110 is provided with a plurality of supporting stations 111 spaced apart along the length and width of the carrier 110. The supporting stations 111 are hollowed out, and the sidewalls of the supporting stations 111 are provided with limiting prisms 112. The top surface of each limiting prism 112 is provided with at least one supporting ramp 113. The supporting ramp 113 supports the sidewalls of the silicon wafer, thereby reducing contact between the bottom surface of the silicon wafer and the carrier 110 and preventing scratches on the wafer.

[0049] See also Figure 4 as well as Figure 5 In some embodiments, the loading mechanism 300 includes a drive assembly 310 and a gripping assembly 320. The drive assembly 310 is adapted to drive the gripping assembly 320 to grip the silicon wafers from the wafer conveying mechanism 200 onto the carrier 110 of the carrier conveying mechanism 100. The gripping assembly 320 includes a connecting frame 321 and a plurality of suction plates 322. The suction plates 322 are spaced apart on the bottom surface of the connecting frame 321, and the arrangement of the suction plates 322 matches the positions of the corresponding silicon wafers being conveyed by the wafer conveying mechanism 200.

[0050] The driving assembly 310 is hoisted on a top slide rail (not shown) for sliding.
