[0036] The present utility model provides a handling mechanism, which is applied to a photovoltaic silicon wafer production line. Among them, the photovoltaic silicon wafer production line is provided with n + 1 processing positions 700 corresponding to the handling mechanism (see Figure 3 ). In this application, the processing position includes the position for processing materials, as well as the loading position where the materials are prepared to enter the processing position and the unloading position where the materials enter the material discharge from the processing position.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 . In an embodiment of the present utility model, the handling mechanism includes:

[0038] A slide rail 100, which is installed on the photovoltaic silicon wafer production line. In this embodiment, there are various ways to install the slide rail 100 on the photovoltaic silicon wafer production line. It can be installed in the photovoltaic silicon wafer production line in a suspended manner. It can also be installed on the machine table in the photovoltaic silicon wafer production line by means of a bracket.

[0039] The moving seat 200 is slidably disposed on the slide rail 100 and is fixedly provided with n gripping members 300, where n is greater than or equal to 2. When the gripping members 300 are configured as two, the two gripping members 300 are arranged on the same side of the slide rail 100. The gripping members 300 are used for picking and placing materials. When the gripping members 300 are arranged as three, at least two gripping members 300 are arranged on the same side of the slide rail 100, and the other gripping member 300 is arranged on the other side of the slide rail 100. When the gripping members 300 are arranged as four, at this time, the four gripping members 300 are divided into two groups, and each group is arranged as two. The two groups of gripping members 300 are respectively arranged on both sides of the slide rail 100. In this embodiment, when the gripping members 300 are arranged on both sides of the slide rail 100, the handling mechanism of the present application can be applied to two photovoltaic silicon wafer production lines to complete the handling of silicon wafers. When the handling mechanism is applied to two photovoltaic silicon wafer production lines, the utilization rate of the handling mechanism can be further improved, so as to achieve the purpose of improving its efficiency, and further improve the production capacity of photovoltaic silicon wafers, solving the technical problems existing in the prior art. When two photovoltaic silicon wafer production lines use one handling mechanism, it can also achieve the purpose of reducing costs while improving the processing production capacity of photovoltaic silicon wafers. The distance between two adjacent gripping members 300 arranged on the same side of the slide rail 100 is the same as the distance between two adjacent processing positions arranged on the same side of the slide rail 100. Specifically, a plurality of gripping members are installed on a moving seat and have synchronism and accuracy during movement. By driving the plurality of gripping members to move, it has high efficiency.

[0040] The driving assembly 400 is used to drive the moving seat 200 to reciprocate along the first direction, so that the gripping members 300 synchronously reciprocate along the first direction, where the first direction is the extending direction of the slide rail 100; when the gripping members 300 move along the first direction, they can transport materials from the previous processing position to the next processing position. Since the distance between two adjacent gripping members 300 arranged on the same side of the slide rail 100 is the same as the distance between two adjacent work positions arranged on the same side of the slide rail 100, when the moving seat 200 drives the gripping members 300 to move in the first direction, the two gripping members 300 can transport two materials at a time, driving the two materials from the previous processing position to the next processing position. In this way, the handling efficiency of the handling mechanism can be improved. At the same time, in this embodiment, when the number of gripping members 300 is set to two, the two gripping members 300 are arranged on the same side of the slide rail 100. At this time, when the handling mechanism of the present application handles materials, it can transport two materials at a time, thereby improving the handling efficiency of the handling mechanism and solving the technical problems existing in the prior art.

[0041] In one embodiment, refer to Figure 3, n of the grippers 300 and n + 1 of the processing positions 700 are both arranged on the same side of the slide rail 100 and are arranged along the first direction. In this embodiment, since the n grippers 300 are all arranged on the same side of the slide rail 100, at this time, the handling mechanism of the present application is applied in a photovoltaic silicon wafer production line, and the n + 1 grippers 300 are arranged along the first direction. Since the first direction is parallel to the moving direction of the material, at this time, when the moving seat 200 drives the n grippers 300 to move, it can realize transporting the material from the previous station to the next station, and at the same time can also transport the material from the next station to the next station further below. In this way, the handling efficiency of the handling mechanism of the present application can be further improved, and at the same time, the moving stroke of the moving seat 200 can be reduced.

[0042] In one embodiment, referring to Figure 3 , the gripper 300 includes a mounting frame 310 and a suction cup 320. Among them, the suction cup 320 is configured as a Bernoulli suction cup 320. The suction cup 320 is fixedly arranged on the mounting frame 310 for picking and placing materials, and the mounting frame 310 is fixedly arranged on the moving seat 200; the processing position 700 includes at least one processing area 710, and the processing area 710 corresponds to the suction cup 320. Further, in this embodiment. When there is one suction cup 320, the corresponding processing area 710 in the processing position 700 is also set to one.

[0043] In one embodiment, referring to Figure 2 、 Figure 4, when two suction cups 320 are provided, the processing areas 710 in the processing positions 700 are also correspondingly provided in two, and the two suction cups 320 are arranged along the second direction, where the second direction is set at a preset angle with the first direction. In this embodiment, the second direction forms a ninety-degree angle with the first direction, that is, the second direction is perpendicular to the extending direction of the slide rail 100, that is, the two suction cups 320 are arranged side by side. At the same time, the corresponding processing areas 710 are also arranged side by side. At this time, in this embodiment, since the n gripping members 300 and the n + 1 processing positions 700 are arranged along the first direction, and the multiple suction cups 320 on each gripping member 300 and the multiple processing areas 710 on each processing position 700 are arranged along the second direction, the handling mechanism can handle multiple materials at one time, that is, each suction cup 320 corresponds to one material. At the same time, when the structure of the material is relatively large, since the suction cups 320 in one gripping member 300 are arranged side by side, at this time, multiple suction cups 320 can also be used to handle one relatively large material to achieve the purpose of handling larger materials, so that while improving the efficiency of the present application, the various uses of the present application can also be improved. However, this design is not limited thereto. In other embodiments, three suction cups 320 can also be provided. When three suction cups 320 are provided, the processing areas 710 in the corresponding processing positions 700 are also correspondingly provided in three. When multiple suction cups 320 are provided, the multiple suction cups 320 can further improve the working efficiency, and at the same time, the number of suction cups on the gripping member in itself is expandable.

[0044] In one embodiment, referring to Figure 2 , the mounting frame 310 includes a first mounting plate 311 and a second mounting plate 312 connected to each other. The first mounting plate 311 is fixedly provided on the moving seat 200. Specifically, the first mounting plate 311 is fixedly provided on the moving seat 200 by means of screw attachment. The suction cup 320 is fixedly provided on the second mounting plate 312. Specifically, the suction cup 320 is fixedly provided on the second mounting plate 312 by means of screw attachment.

[0045] In one embodiment, referring to Figure 1 , when the handling mechanism of the present application is installed on a machine table (not shown) of a photovoltaic silicon wafer production line, the handling mechanism further includes a support seat 600, and the slide rail 100 is fixedly provided on the support seat 600. A plurality of support seats 600 are provided, and the slide rail 100 is installed on the machine table through the support seats.

[0046] In one embodiment, referring to Figure 1 , the drive assembly 400 includes a drive motor 410 and a transmission assembly 420. The transmission assembly 420 is installed on the slide rail 100 and is connected to the moving seat 200. The drive motor 410 is drivingly connected to the transmission assembly 420.

[0047] In this embodiment, the transmission assembly 420 can also be configured as follows. Refer to Figure 1 , for example, the transmission assembly 420 is configured as a belt module. When the transmission assembly 420 is set as a belt module, the belt in the belt module is connected to the moving seat 200. By driving the motor 410 to drive the belt in the belt module to rotate, the moving seat 200 is driven to move along the slide rail 100 through the belt. However, this design is not limited thereto. In other embodiments, the transmission assembly 420 can be a gear rack (not shown). When the transmission assembly 420 is configured as a gear rack, the rack is fixedly arranged on the slide rail 100, the gear is installed at the output end of the driving motor 410 and meshes with the rack. At the same time, the driving motor 410 is installed on the moving seat 200. At this time, by rotating the driving motor 410, the gear rotates. At this time, the gear can move on the rack during rotation, so that the moving seat 200 moves along the slide rail 100.

[0048] In one embodiment, refer to Figure 1 , when the transmission assembly 420 is set as a belt module, in order to facilitate the driving assembly 400 to drive the moving seat 200 to reciprocate along the first direction. At this time, the handling mechanism further includes a drag chain 500. The drag chain 500 is slidably installed on the slide rail 100. Under the action of the drag chain 500, the connection lines in the handling mechanism can be protected, so that the ends of the connection lines can move following the movement of the moving seat 200.

[0049] In one embodiment, refer to Figure 1 , the drag chain 500 is installed on the top of the slide rail 100. In this embodiment, when the drag chain 500 is installed on the top of the slide rail 100, it is convenient for the drag chain 500 to slide on the slide rail 100, and it is also convenient for laying lines. At the same time, it is also convenient for installing the air pipe connected to the suction cup 320, and it is convenient for the air pipe to move following the movement of the suction cup 320.
