Description
Technical Field
[0001] The utility model relates to the technical field of silicon wafer conveying, in particular to a chain-type loading and unloading machine. Background Art
[0002] During the transportation of silicon wafers, chain loading and unloading machines are often used. The traditional structure is as follows Figure 1 As shown, three groups of mechanisms are arranged side by side, and six silicon wafers are loaded and transported forward at the same time. Two silicon wafers form a group and share one group of mechanisms. They are first transported in two ways, and then merged into one way for unloading by using a transverse movement mechanism. The above-mentioned mechanisms are numerous and the overall cost of use is high. Summary of the invention
[0003] In order to solve the problem of high use cost of existing silicon wafer loading and unloading machines, the utility model provides a chain loading and unloading machine, which can reduce the number of mechanisms and reduce the use cost.
[0004] The technical solution is as follows: a chain loading and unloading machine, which includes a loading conveyor mechanism and a unloading conveyor mechanism, a material dividing mechanism is arranged between the loading conveyor mechanism and the unloading conveyor mechanism, and is characterized in that the material dividing mechanism includes three groups of intermediate conveying mechanisms arranged side by side, each group of the intermediate conveying mechanisms includes a first conveyor belt device, a second conveyor belt device, a third conveyor belt device, and a fourth conveyor belt device arranged in sequence, each of the first conveyor belt devices and each of the fourth conveyor belt devices are respectively provided with an independent first motor, all of the second conveyor belt devices are connected by a first transmission rod and driven by the same second motor, all of the third conveyor belt devices are connected by a second transmission rod and driven by the same third motor, a first traverse conveying mechanism that can be raised and lowered is arranged between the first conveyor belt device and the second conveyor belt device, a second traverse conveying mechanism that can be raised and lowered is arranged between the third conveyor belt device and the fourth conveyor belt device, and the first traverse conveying mechanism and the second traverse conveying mechanism realize the translation of silicon wafers between the three groups of the intermediate conveying mechanisms.
[0005] Its further feature is that the first transverse conveying mechanism and the second transverse conveying mechanism both include a lifting seat connected to a lifting drive mechanism, the lifting seat is provided with a transverse belt mechanism, two adsorption blocks are fixed on the belt of the transverse belt mechanism, the two adsorption blocks are located between the belt group of the first conveying belt device and between the belt group of the fourth conveying belt device, and the spacing between the two adsorption blocks is consistent with the spacing between the two adjacent intermediate conveying mechanisms.
[0006] After the utility model is adopted, the silicon wafers transported by the loading conveyor mechanism arrive at the three groups of intermediate conveyor mechanisms, and can be sent to the intermediate conveyor mechanisms on both sides by the first transverse conveyor mechanism or the intermediate conveyor mechanism without intervention to allow the silicon wafers to enter the middle position, thereby realizing one-to-three silicon wafers. Before entering the unloading conveyor mechanism, the second transverse conveyor mechanism can be used to realize three-in-one again. Compared with the existing one-to-two mechanism, when conveying six silicon wafers at the same time, the number of mechanisms can be effectively reduced, thereby reducing the cost of use.

[0011] See Figures 2 to 4 As shown, a chain loading and unloading machine includes a loading conveyor mechanism 1 and a unloading conveyor mechanism 2, a material dividing mechanism 3 is arranged between the loading conveyor mechanism 1 and the unloading conveyor mechanism 2, the material dividing mechanism 3 includes three groups of intermediate conveying mechanisms arranged side by side, each group of intermediate conveying mechanisms includes a first conveyor belt device 4, a second conveyor belt device 5, a third conveyor belt device 6, and a fourth conveyor belt device 7 arranged in sequence, each first conveyor belt device 4 and each fourth conveyor belt device 7 are respectively provided with an independent first motor 8, all the second conveyor belt devices 5 are connected by a first transmission rod and driven by the same second motor 9, all the third conveyor belt devices 6 are connected by a second transmission rod and driven by the same third motor 10, a liftable first transverse conveying mechanism 11 is arranged between the first conveyor belt device 4 and the second conveyor belt device 5, a liftable second transverse conveying mechanism 12 is arranged between the third conveyor belt device 6 and the fourth conveyor belt device 7, and the first transverse conveying mechanism 11 and the second transverse conveying mechanism realize the translation of 12 silicon wafers between the three groups of intermediate conveying mechanisms.
[0012] Specifically, the first transverse conveying mechanism 11 and the second transverse conveying mechanism 12 each include a lifting seat connected to a lifting drive mechanism 13, a transverse belt mechanism is provided on the lifting seat, two adsorption blocks 14 are fixed on the belt of the transverse belt mechanism, the two adsorption blocks 14 are located between the belt group of the first conveyor belt device 4 and between the belt group of the fourth conveyor belt device 7, and the spacing between the two adsorption blocks 14 is consistent with the spacing between the two adjacent intermediate conveying mechanisms.
[0013] The working principle is as follows: the first silicon wafer is conveyed forward from the loading conveyor mechanism 1 and reaches the first conveyor belt device 4 of the intermediate conveyor mechanism in the middle position. The first transverse conveyor mechanism 11 rises and adsorbs the silicon wafer, and then the belt moves to move the silicon wafer to the first conveyor belt device 4 of the intermediate conveyor mechanism on the left, and the silicon wafer continues to be conveyed forward. The second silicon wafer reaches the first conveyor belt device 4 of the intermediate conveyor mechanism in the middle position and continues to be conveyed forward. The third silicon wafer reaches the first conveyor belt device 4 of the intermediate conveyor mechanism in the middle position. The first transverse conveyor mechanism 11 rises and adsorbs the silicon wafer, and then the belt moves to move the silicon wafer to the right. On the first conveyor belt device 4 of the intermediate conveying mechanism, the silicon wafer continues to be conveyed forward, and the fourth silicon wafer begins to repeat the above operation. Since all the first conveyor belt devices 4 and the fourth conveyor belt devices 7 work independently of each other, the same group of first conveyor belt devices 4, second conveyor belt devices 5, third conveyor belt devices 6, and fourth conveyor belt devices 7 are also independent of each other, and the conveying speed of the conveyor belt can be adjusted, so that the three silicon wafers can reach their respective fourth conveyor belt devices 7 in different time periods, and then use the second transverse conveying mechanism 12 to transfer the silicon wafers on both sides to the middle fourth conveyor belt device 7, and then continue to be conveyed to the unloading conveying mechanism 2 for unloading.
[0014] The device of the present application can split a silicon wafer into three and then combine three into one, thereby realizing simultaneous transportation of three wafers, which can save the number of mechanisms and reduce costs.
