AI Technical Summary
Traditional silicon wafer material picking and discharge mechanisms have difficulties in increasing production capacity. The equipment is large in size and high in cost. In order to increase production capacity, the number of gantry jaws and step belts needs to be increased, resulting in an increase in the volume of equipment and affecting the flexibility and stability of the equipment.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of photovoltaic equipment, in particular to a flexible silicon chip taking and placing mechanism. Background Art
[0002] With the rapid development of photovoltaics today, for photovoltaic cell production lines, improving the production capacity of the entire line equipment and reducing the equipment size and production costs have always been the constant topics in the entire history of photovoltaic development. As large-size cells are constantly needed by new markets, the overall size of the equipment is gradually increasing, and the hardware cost is also rising, and reducing the cost of cells has encountered resistance. The optimization of the production capacity of the traditional silicon wafer loading and unloading mechanism is becoming increasingly difficult, and large-size wafers have higher requirements for floor space and production capacity. The increase in production capacity needs to be compensated by continuously increasing the number of gantry grippers and stepping belts, which will affect the size of the equipment. The impact on the future optimization of silicon wafer production capacity will become more and more prominent, which is not conducive to adapting to the development of the industry market.
[0003] The mainstream silicon wafer grabbing method on the market is to use multiple sets of independent gantry grippers, each set of gantry grippers corresponds to 2-3 belts, and each is controlled in different areas. This structural control method is relatively simple, but it occupies a large space. When the number of belts is insufficient, there is a waiting time for changing the flower basket, and the flexibility is not enough. At the same time, the traditional gantry clamping method requires several different area pick-and-place modules to realize the placement of the wafer, which requires the carrier to run during transmission, increasing the transmission time. At the same time, after the carrier stops, new cumulative errors are generated and need to be repositioned, which will affect the entire carrier cycle. If you want to increase production capacity in the future, you need to increase the transmission speed or add new area grabbing modules to achieve this, which will increase the length of the equipment.
[0004] Therefore, designing a silicon wafer loading and unloading mechanism that can effectively reduce the equipment size and reduce the equipment cost, while increasing the wafer production capacity and reducing the space occupied in the workshop is of great significance to the future development of the industry and has good application prospects. Utility Model Content
[0005] In view of the above problems, the utility model provides a flexible silicon wafer loading and unloading mechanism which can effectively reduce the size of the equipment and reduce the equipment cost, while increasing the wafer production capacity and reducing the space occupied by the workshop.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a flexible silicon wafer loading and unloading mechanism, including a multi-motor transfer module, two sets of parallel double-layer drag chain support mechanisms, and a gantry transfer robot. The multi-motor transfer module realizes the walking accuracy of the gantry transfer robot through the power form of the gantry double drive. The gantry transfer robot is installed between the two sets of double-layer drag chain support mechanisms. The gantry transfer robot is controlled by multiple sets of flexibility, so that each gantry transfer robot stays at any position in the entire travel range. The double-layer drag chain support mechanism includes an upper transfer drag chain supporting sheet metal, a lower transfer drag chain supporting sheet metal, and a lower transfer drag chain supporting sheet metal. Chain support sheet metal, fixed end upper drag chain support plate, fixed end lower drag chain support plate and drag chain, the upper transfer drag chain support sheet metal and the lower transfer drag chain support sheet metal are respectively fixedly connected to their own gantry transfer manipulators, and the drag chains are moved on their own layers driven by the gantry transfer manipulator. The fixed end upper drag chain support plate and the fixed end lower drag chain support plate are divided into two layers of high and low layers and the drag chains are respectively arranged. The gantry transfer manipulator includes a support lifting mechanism, an opening and closing mechanism, a clamping mechanism and a centering mechanism. The support lifting mechanism is arranged on both ends and is respectively installed on the double-layer drag chain support mechanism. The opening and closing mechanism drives the clamping mechanism to open and close.
[0007] Furthermore, the gantry transfer robot adopts two protection modes: soft limit and hard limit.
[0008] Furthermore, the opening and closing mechanism includes a reduction motor, a slider mechanism, a cam, and a tension spring. The reduction motor drives the cam to rotate, thereby driving the clamping claw mechanism connected to the slide rail slider mechanism to open or close.
[0009] Furthermore, the centering mechanism is driven by a cylinder to push the slider mounting plate to move, thereby moving the connecting rod connecting block, thereby driving the connecting rod and pin, the centering rod, and the limit block to form a multi-link mechanism to swing.
[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:
[0011] This utility model adopts a double-layer drag chain support mechanism design, and different drag chains are placed on the high and low layers to save the width space of the equipment. The support mechanism can support the long film direction, reduce the amount of film under the film, and improve stability. While effectively reducing the equipment size and reducing the equipment cost, it increases the film production capacity and reduces the space occupied in the workshop. At the same time, the expansion of production capacity can be achieved by adding linear movers or gear rack movers without increasing the equipment space, and the subsequent production improvement and transformation are also more convenient.
