[0032] like Figures 1 to 4 As shown, the photovoltaic wafer locator disclosed in Embodiment 1 of this application includes: a mounting frame assembly 10 and a positioning platform assembly 20. The mounting frame assembly 10 includes a plurality of mounting slot structures 11, which are arranged at intervals. The positioning platform assembly 20 includes a platform structure 21, a first clamping structure 22 and a second clamping structure 23. The mounting frame assembly 10 is disposed on the platform structure 21. The first clamping structure 22 is movably connected to the platform structure 21, and the second clamping structure 23 is movably connected to the platform structure 21. The first clamping structure 22 and the second clamping structure 23 are both correspondingly arranged with respect to the mounting frame assembly 10.

[0033] By applying the technical solution of Embodiment 1, multiple photovoltaic wafers are respectively placed in different mounting slot structures 11, and the mounting frame assembly 10 is placed on the platform structure 21. The first clamping structure 22 and the second clamping structure 23 jointly clamp the mounting frame assembly 10 to prevent it from moving. Simultaneously, multiple photovoltaic wafers on the mounting frame assembly 10 are positioned, resulting in high positioning efficiency. The technical solution of Embodiment 1 effectively solves the problem of low processing efficiency caused by slow positioning during the processing of multiple wafers in the prior art.

[0034] like Figure 1 and Figure 3 As shown, in the technical solution of Embodiment 1, the mounting frame assembly 10 includes a connecting structure 12 and a mounting structure 13. Two mounting structures 13 are connected to the connecting structure 12 and located on both sides of the connecting structure 12. Mounting groove structures 11 are disposed on the mounting structures 13, with the two sides of the photovoltaic wafer respectively located within the two corresponding mounting groove structures 11. The connecting structure 12 connects the two mounting structures 13 together. The two sets of mounting groove structures 11 on the two mounting structures 13 are correspondingly arranged. The two sides of the photovoltaic wafer extend into the two corresponding mounting groove structures 11 to achieve wafer positioning. Multiple photovoltaic wafers can be correspondingly disposed on multiple sets of mounting groove structures 11. Positioning the mounting frame assembly 10 simultaneously achieves the positioning of multiple photovoltaic wafers, resulting in high positioning efficiency and improved subsequent processing efficiency.

[0035] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the first clamping structure 22 includes a limiting part 221, a force-applying part 222, and an elastic member 223. The platform structure 21 includes a fixed platform 211 and a mounting part 212. The mounting part 212 is connected to the fixed platform 211, the limiting part 221 is connected to the fixed platform 211, the first end of the elastic member 223 is connected to the mounting part 212, and the second end of the elastic member 223 is connected to the force-applying part 222. The mounting bracket assembly 10 is located between the limiting part 221 and the force-applying part 222. The force-applying part 222 is movably connected to the platform structure 21. The force-applying part 222 has a clamping state close to the limiting part 221 and a waiting-to-clip state away from the limiting part 221. During the positioning process, the mounting frame assembly 10, which houses multiple photovoltaic cells, is placed on the platform structure 21. One side of the mounting frame assembly 10 abuts against the limiting part 221. The elastic element 223 remains compressed. Under the elastic force of the elastic element 223, the force-applying part 222 abuts against the side of the mounting frame assembly 10 opposite to the limiting part 221, thereby clamping the mounting frame assembly 10 and preventing it from shaking. The first clamping structure 22 also includes a guide post, which passes through the elastic element 223 and is movably connected to the mounting part 212. The guide post prevents the elastic element 223 from moving radially, which would cause the elastic element 223 to shift position and fail to abut against the force-applying part 222 to provide sufficient power to the force-applying part 222, thus affecting the clamping effect of the first clamping structure 22.

[0036] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the force-applying part 222 has multiple limiting protrusions, and the fixed platform 211 has multiple first slides 2111. The multiple limiting protrusions are correspondingly arranged with the multiple first slides 2111, and the limiting protrusions are movably arranged within the first slides 2111. The first slides 2111 have an elongated hole structure. The limiting protrusions and the first slides 2111 guide the movement of the force-applying part 222, preventing the movement of the force-applying part 222 from deviating, which would cause the first clamping structure 22 to fail to properly clamp the mounting bracket assembly 10, making it impossible to position the mounting bracket assembly 10 and causing problems such as shaking during processing.

[0037] like Figure 1 and Figure 2As shown, in the technical solution of Embodiment 1, the fixed platform 211 further includes a second slide rail 2112, and the second clamping structure 23 includes a clamping section 231 and a limiting section 232. The limiting section 232 is movably disposed within the second slide rail 2112. The clamping section 231 is connected to the limiting section 232. There are two clamping sections 231, which have a clamping state close to each other and a clamping state far apart from each other. The second slide rail 2112 has an elongated hole structure, and the limiting section 232 passes through the second slide rail 2112. The structure of the second slide rail 2112 and the limiting section 232 cooperates to limit the movement of the clamping section 231, preventing the movement of the clamping section 231 from deviating, and controlling the two clamping sections 231 to clamp the mounting bracket assembly 10 respectively. In Embodiment 1, the first slide rail 2111 and the second slide rail 2112 are arranged perpendicularly to each other, so that the first clamping structure 22 and the second clamping structure 23 clamp the mounting frame assembly 10 from two directions respectively, preventing the mounting frame assembly 10 from moving in the horizontal direction and ensuring the accuracy of positioning.

[0038] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the second clamping structure 23 further includes a screw 233, and the limiting section 232 has a threaded hole that mates with the screw 233, with the screw 233 passing through the threaded hole. The end of the limiting section 232 away from the clamping section 231 extends out of the second slide rail 2112 and mates with the screw 233 located below. Under the action of the threaded transmission, the rotation of the screw 233 causes the limiting section 232 to move along the axis of the screw 233, and the clamping section 231 connected to the limiting section 232 moves accordingly, thereby clamping the mounting bracket assembly 10. The threaded transmission method is stable and reliable, and facilitates maintenance and replacement. One end of the screw 233 is connected to a handwheel, making it convenient for operators to rotate the screw 233.

[0039] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1, the limiting segment 232 includes two segments corresponding to the clamping segment 231. The screw 233 includes a first threaded segment and a second threaded segment, which are connected to each other. The threads on the first and second threaded segments have opposite directions of rotation and cooperate with the two limiting segments 232 respectively. The threaded holes of the two limiting segments 232 have opposite directions of rotation and cooperate with the first and second threaded segments respectively. When the screw 233 is rotated, the two limiting segments 232 move simultaneously in opposite directions, achieving simultaneous movement towards or away from each other, thus completing the clamping and releasing of the mounting bracket assembly 10. The structure of the first and second threaded segments having opposite directions of rotation allows for synchronous control of the movement of the two clamping segments 231 while rotating the screw 233, resulting in higher clamping efficiency.

[0040] like Figure 1 and Figure 3 As shown, in the technical solution of Embodiment 1, the mounting frame assembly 10 further includes a support structure 14. The two ends of the support structure 14 abut against two mounting structures 13, and are located on the side of the mounting structures 13 away from the connecting structure 12. The support structure 14 is configured according to the wafer size. The second clamping structure 23 clamps the mounting frame assembly 10 and abuts the two mounting structures 13 against the support structure 14, limiting the minimum distance between the support structures 14. This prevents problems such as deformation of the connecting structure 12 and the photovoltaic wafer within the mounting frame assembly 10 due to a small distance between the two mounting structures 13 caused by a large clamping force of the second clamping structure 23.

[0041] like Figure 1 and Figure 3 As shown, in the technical solution of Embodiment 1, the mounting structure 13 includes a first connecting section 131 and a second connecting section 132. The first connecting section 131 is connected to the second connecting section 132, and the second connecting section 132 is connected to the connecting structure 12. The vertical height of the first connecting section 131 is higher than the vertical height of the support structure 14. The mounting groove structure 11 is disposed on the second connecting section 132. The higher vertical height of the first connecting section 131 than the vertical height of the support structure 14 ensures that the support structure 14 abuts against the side wall of the first connecting section 131, preventing the support structure 14 from interfering with the photovoltaic cells located in the mounting groove structure 11 above.

[0042] The difference between the technical solution of Embodiment 2 and Embodiment 1 is that the connecting structure 12 includes a first connecting part and a second connecting part, which are movably connected. The first connecting part is sleeved on the second connecting part, and two mounting structures 13 are respectively connected to the first connecting part and the second connecting part. The first connecting part has multiple first connecting holes, and the second connecting part has multiple second connecting holes. Different first connecting holes and second connecting holes are connected by bolts and fasteners, thereby changing the distance between the two mounting structures 13. This makes it suitable for mounting photovoltaic cells of different sizes and positioning photovoltaic cells of different sizes, thus improving its versatility. Correspondingly, the support structure 14 adopts a telescopic rod structure, which is set according to the distance between the two mounting structures 13.

[0043] In summary, the rear movable fixed block (force application part 222) is in its original position under the elastic force of the spring (elastic element 223). At this time, the screw head of the screw is limited, and the forward and reverse grippers (clamping section 231) are at both ends of the slot. Working process: Place the material box (mounting bracket assembly 10) in front of the rear movable block, and push the material box backward to compress the spring until the material box is inserted between the rear movable block and the front block (limiting part 221). At this time, rotating the handwheel drives the lead screw (screw 233) to rotate. Since the left and right sides of the lead screw have reverse threads, it drives the reverse thread slider (limit section 232) and the forward thread slider (limit section 232) to move, which in turn drives the clamping block (clamping section 231) mounted on it to move. Rotating the handwheel clockwise or counterclockwise will clamp or release the clamping block. After the material box is positioned in the front and back directions, adjusting the handwheel to clamp the material box completes the positioning. When using material boxes of different sizes, simply adjust the rear movable stop and clamping block to the appropriate position. If the material box size is too large or too small, consider replacing the appropriate spring and screw. This application has a simple structure, can quickly and accurately complete positioning, saves manual material changing time, and the size of each stop of the positioning device is adjustable to meet the needs of various sizes. The front and back positions of the material box are positioned by the spring driving the movable stop, and the left and right positions are positioned by rotating the handwheel to clamp the material box. The structure is simple and fast; there is a large adjustable space in the front, back, left and right directions, which can be used for various sizes of material boxes.
