Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crystal bar gluing, and particularly relates to a crystal bar gluing device. BACKGROUND

[0002] In the process of manufacturing single crystal silicon wafers at the integrated circuit level, large-size single crystal silicon rods are generally cut by multi-wire cutting technology, and the single crystal silicon rods need to be bonded to a workpiece plate before being cut by wires. The main purpose of bonding the single crystal silicon rods is to fix the single crystal silicon rods according to the crystal direction of the single crystal silicon rods, to realize non-destructive clamping of the single crystal silicon rods during wire cutting, and to keep the cutting direction and the crystal direction fixed, so as to avoid adverse conditions such as crystal direction deviation, wafer edge collapse and fragments during cutting. Therefore, the bonding of the single crystal silicon rods is the first process in the manufacturing of silicon wafers, and has a significant impact on the subsequent processing and yield of products.

[0003] The traditional crystal bar gluing method usually places the crystal bar on a gluing table first, and then a technician glues the crystal bar by skilled gluing methods to ensure the uniformity of gluing. Therefore, this method has high dependence on manual work, and if the technician is not careful, the glue will leak on the workbench. If the workbench is not cleaned in time, the next batch of crystal bars will be affected in subsequent processing quality due to the contamination of residual glue. Therefore, maintaining the cleanliness of the workbench undoubtedly increases the labor cost. CONTENT OF THE INVENTION

When the crystal bar 8 is placed in the positioning rack, the displacement signal of the crystal bar received by the first displacement sensor is transmitted to the control processor group through the first input end. The control processor group compares the displacement signals of the crystal bar and the glue outlet pipe, controls the running state of the corresponding motor according to the deviation of the two displacement signals, adjusts the position of the glue outlet pipe 60, and controls the uniform movement of the glue outlet pipe, so as to simulate the uniform glue coating of the technician.
