Description

Technical Field

[0001] The utility model relates to the technical field of silicon wafer conveying, in particular to an independent wafer arrangement device for a chain feeder. Background Art

[0002] Silicon wafers need to be transported during the production process. A common method is to use a chain feeder, which generally includes a front-end conveying mechanism, a flipping mechanism, and a back-end conveying mechanism. When a silicon wafer has defects, it needs to be discharged from the feeder. The existing practice is to set up a wafer discharge mechanism at the back-end conveying mechanism. Since the conveyor line is a two-in-one form, the silicon wafers need to pass through the front-end conveying mechanism and the flipping mechanism first. Some silicon wafers may also need to be moved horizontally by a transverse transport mechanism before they can reach the back-end conveying mechanism for wafer discharge. The operation is cumbersome, the wafer discharge method is single, and the functionality is not strong. Summary of the invention

[0003] In order to solve the problem of single function of existing feeders, the utility model provides an independent sheet arrangement device for a chain feeder, which can realize independent sheet arrangement of the feeder and improve the functionality of the product.

[0004] The technical solution is as follows: an independent film arrangement device for a chain feeder, which includes a front-end conveying mechanism, a flipping mechanism, and a back-end conveying mechanism, the front-end conveying mechanism includes six roller conveying devices, the flipping mechanism includes six belt conveying devices and six groups of turntables arranged on both sides of the belt conveying device, and the turntables are evenly provided with card slots, and the back-end conveying mechanism includes three conveyor belt devices, two of the roller conveying devices, two of the belt conveying devices and one of the conveyor belt devices form a group of independent conveying mechanisms, the conveyor belt device includes a movable conveyor belt device and a fixed conveyor belt device, the movable conveyor belt device is connected to a first swinging cylinder, and the fixed conveyor belt device is provided with a first material receiving tray corresponding to the movable conveyor belt device under one end close to the movable conveyor belt device, characterized in that the roller conveying device includes a movable roller conveying device and a fixed roller conveying device, the movable roller conveying device is connected to a second swinging cylinder, and the fixed roller conveying device is provided with a second material receiving tray corresponding to the movable roller conveying device under one end close to the movable roller conveying device.

[0005] Its further feature is that the front conveying mechanism and the back conveying mechanism are installed on the workbench, the belt conveyor of the turnover mechanism is installed on the workbench, all the turntables are connected by connecting rods and the two ends of the connecting rods are respectively connected to the top of the lifting seat, a turning motor connected to one end of the connecting rod is installed on the lifting seat on one side, the belt conveyor is a segmented structure and has notches with a spacing greater than the outer diameter of the connecting rod, and the bottom of the lifting seat is connected to the lifting drive cylinder;

[0006] The workbench is provided with a guide seat, a fixed guide block is provided on the guide seat, and a guide rail matching with the fixed guide block is provided on the outer side of the lifting seat;

[0007] A limiting plate is arranged at the flip motor, and a limiting bolt cooperating with the limiting plate is arranged at the top of the guide seat.

[0008] After adopting the utility model, a sheet discharging mechanism is also provided at the front conveying mechanism. When a defective silicon wafer enters the front conveying mechanism, it does not need to pass through the flipping mechanism and then reach the back conveying mechanism for sheet discharging. The second swing cylinder can directly drive the movable roller conveying device to swing downward, allowing it to directly enter the second receiving tray, eliminating the subsequent conveying process. The six roller conveying devices perform sheet discharging independently of each other. Silicon wafers with defects found at the flipping mechanism can still be discharged at the back conveying mechanism, thereby improving the functionality of the product. Furthermore, the turntable mechanism can realize the flipping of the silicon wafer. When the silicon wafer does not need to be flipped, the lifting drive cylinder can be used to lift the entire turntable higher than the belt conveyor without contacting the silicon wafer, and the flipping process can be cancelled, thereby better improving the practicability and functionality of the product and meeting different conveying requirements.
