[0087] Continuous insertion method

[0088] A continuous inserting method based on the above-mentioned inserting device, see Figure 13 , the continuous inserting method includes the following steps.

[0089] Slicing: The cut silicon wafers are transported to the slicing water tank 110 of the slicing module 100 through a flower basket. The flower basket is placed horizontally and the silicon wafers are placed vertically. The wafer pushing unit 120 pushes the silicon wafers forward, and the side spray unit 130 flushes and disperses the pushed silicon wafers from the side to achieve slicing;

[0090] The water absorption plate group 220 of the wafer extraction module 200 absorbs the adjacent silicon wafers, and the absorbed silicon wafers are lifted and climbed by the lifting belt group 230 and the arc-shaped climbing component 240, and then transferred to horizontal transportation.

[0091] Pre-sorting and horizontal conveying: The pre-sorting and wafer conveying module 300 inspects the horizontally conveyed silicon wafers for defects and thickness, removes unqualified wafers, and conveys qualified wafers horizontally to the wafer insertion station. Air knives are used to remove water from the wafers. Unqualified wafers include wafers with defects such as chips and scratches, as well as stacked wafers. Furthermore, the pre-sorting and wafer conveying module 300 accelerates the horizontally conveyed wafers step by step to the wafer insertion station, increasing the spacing between wafers to prevent wafer collisions due to insufficient time and facilitating wafer insertion.

[0092] Inserting wafers, the quick basket changing module 400 circulates the supply of empty baskets and transfers full baskets. At the inserting station, the quick basket changing module 400 lifts the vertically arranged empty baskets layer by layer and receives the horizontally transported silicon wafers layer by layer. After the basket is full of silicon wafers, the quick basket changing module 400 transfers the full basket to the entry and exit position.

[0093] After the empty baskets are supplied, the flower basket hoisting module 700 hoists the prepared empty flower baskets in a horizontal state to the empty flower basket flipping module 500, and the empty flower basket flipping module 500 transports the horizontal flower baskets and flips them into a vertical position. Finally, the vertical empty flower baskets are transported to the entry and exit positions of the quick basket changing module 400.

[0094] Full basket transfer: the full flower basket located at the entry and exit position of the quick basket change module 400 is transferred in a vertical state to the full flower basket flipping and conveying module 600, and the full flower basket flipping and conveying module 600 flips the full flower basket into a horizontal state, and the flower basket hoisting module 700 transfers the full flower basket in a horizontal state to the subsequent work station.

[0095] The above steps are executed in no particular order and are repeated repeatedly.

[0096] Empty flower baskets come from the empty flower basket station, such as the empty flower baskets after the subsequent sorting machine has processed the materials, and the empty flower baskets for replenishment and spare parts are transferred to an empty flower basket flow line station.

[0097] The subsequent workstations to which the full flower baskets are transferred include drying, labeling, sorting, etc.
