[0002] With the rapid development of photovoltaics today, for photovoltaic cell production lines, improving the production capacity of the entire line equipment and reducing equipment size and production costs have always been the constant topics in the entire history of photovoltaic development. As large-size cells are constantly required by new markets, the overall size of equipment is gradually increasing, and the hardware cost is also rising, and reducing the cost of cells has encountered resistance.
[0003] The mainstream silicon wafer positioning method on the market is to first lift the silicon wafer through the correction mechanism, then take a visual photo, and feedback information to the correction mechanism, which then performs correction positioning, and finally the gripper mechanism grabs the silicon wafer. This method has high positioning accuracy, but the cost of vision and correction mechanisms is too high, which creates great resistance to equipment cost reduction and is not conducive to the development of the industry market.
[0004] Therefore, designing a device that can replace the visual photography and correction mechanism can greatly reduce the mechanism cost, wiring and debugging difficulty, which is of great significance to the future development of the industry and has good application prospects. Utility Model Content

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a four-way correctable silicon wafer clamping mechanism, including left and right support mechanisms, a lifting support mechanism, and a correcting clamping mechanism. The left and right support mechanisms and the lifting support mechanisms are provided with two groups, which are symmetrically arranged on both sides of the correcting clamping mechanism. The lifting support mechanism is fixedly installed on the left and right support mechanisms. The lifting support mechanism includes a lifting servo motor, a lifting screw module, a support assembly, a junction box, a drag chain, and a solenoid valve. The lifting servo motor drives the support assembly to rise and fall on the lifting screw module. The junction box, the drag chain, and the solenoid valve cooperate so that the wiring and the air pipe are all arranged on the support assembly. The correcting clamping mechanism is composed of left and right clamping devices and front and rear alignment devices.
[0007] Preferably, the left and right clamping devices are driven by an electric cylinder installed on an electric cylinder support seat to push a slider mounting plate to move, and the slide rail connecting plate locked on the slider mounting plate drives the left slide rail assembly to move left and right, driving the left limit clamp installed on the slide rail assembly to open or close, and the right limit clamp installed on the right slide rail assembly is driven in the opposite direction by a relatively arranged driving assembly.
[0008] Preferably, the left slide rail assembly and the right slide rail assembly are arranged in parallel and staggered manner.
[0009] Preferably, the left limiting jaw and the right limiting jaw are respectively installed on the left slide rail assembly and the right slide rail assembly at equal intervals, and the limiting distance between the left limiting jaw and the right limiting jaw is adjustable.
[0010] Preferably, the front and rear straightening device is composed of two groups of front and rear correspondingly arranged swing cylinders, couplings, rotating shaft support seats, bearings, rotating shafts and front and rear straightening components. The swing cylinder drives the rotating shaft supported on the rotating shaft support seat and the bearing to rotate through the coupling, so that the front and rear straightening components installed on the rotating shaft swing, thereby realizing the avoidance film and the straightening film.
