Die bonding is an extremely important link in the semiconductor device packaging process. The main work flow of die bonding is to bond the chip to the designated area of ​​the carrier through colloid to form a thermal path or electrical path, providing conditions for subsequent wire bonding.

[0003] With the rapid development of the electronics industry, traditional manual dispensing is not only inefficient, but also difficult to ensure quality consistency and stability. Therefore, various automated dispensing equipment has gradually become the mainstream choice in recent years. Automated dispensing equipment generally includes a workbench, a moving mechanism, a dispensing head and a carrier. The moving mechanism is arranged on the workbench, and the dispensing head is connected to the moving mechanism. The moving mechanism drives the dispensing head to move in the three directions of the X-axis, Y-axis and Z-axis. The carrier is fixedly connected to the workbench, and a carrier is carried on the carrier. The moving mechanism drives the dispensing head to move to the carrier, so as to dispense glue to the semiconductor device on the carrier.

[0004] However, the automated dispensing equipment in the related art relies on a multi-axis moving mechanism to achieve precise positioning, and dispensing deviations may accumulate after long-term operation, affecting the quality of the final product. Summary of the invention

[0005] In order to improve the situation where dispensing deviations may accumulate after long-term operation, the present application provides a single-head dispensing machine and a dispensing control method.

[0006] The present application provides a single-head dispensing machine, which adopts the following technical solution: In a first aspect, the present application provides a single-head dispensing machine, comprising: Workbench; A moving mechanism, wherein the moving mechanism is arranged on the workbench; A carrying platform, the carrying platform is used to carry and adsorb the carrier; A glue dispensing head, the glue dispensing head is connected to the moving mechanism, the moving mechanism drives the glue dispensing head to move, and the glue dispensing head dispenses glue on the carrier; A calibration detection component, wherein the calibration detection component includes a visual detection component and a calibration table, wherein the calibration table is connected to the workbench, and the visual detection component is connected to the moving mechanism, and the moving mechanism drives the visual detection component to move along with the dispensing head; the visual detection component is used to detect and identify the calibration table, so that the moving mechanism drives the visual detection component to align with the calibration table.

[0007] By adopting the above technical solution, the visual inspection part can detect and identify the calibration table, so that the moving mechanism drives the visual inspection part to align with the calibration table, thereby calibrating the position of the dispensing head, ensuring the accuracy and consistency of the dispensing operation, and reducing product quality problems caused by the accumulation of dispensing deviations.

The moving mechanism drives the distance detection component to move along with the dispensing head, and the distance detection component detects the distance between itself and the carrier located on the supporting platform.

[0011] By adopting the above technical solution, the moving mechanism drives the dispensing head and the distance detection component to approach the carrier, and the distance detection component detects the distance between itself and the carrier located on the supporting platform. When the distance detection component detects that the distance reaches a predetermined value, the dispensing head discharges glue, thereby improving the dispensing accuracy.

[0012] Optionally, the supporting platform includes a fixed plate, an adsorption trough body and a top plate, the fixed plate is connected to the workbench, the adsorption trough body is connected to the fixed plate, the top plate is connected to the adsorption trough body, the top plate is provided with a plurality of through holes, the through holes are connected to the adsorption trough body, and the adsorption trough body is externally connected to a vacuum pump.

[0021] By adopting the above technical solution, the moving mechanism drives the dispensing head to contact the cleaning belt body, and then the cleaning drive source drives the winding roller to rotate, so that the cleaning belt body moves, which can effectively clean the dispensing head. The design of the winding roller and the unwinding roller allows the cleaning belt body to be continuously updated, reducing the problem of contamination of the cleaning belt body caused by repeated use.

[0022] Optionally, the moving mechanism includes an X-axis slide, a Y-axis slide and a Z-axis slide, the X-axis slide is arranged on the workbench, the Y-axis slide is connected to the X-axis slide, the Z-axis slide is connected to the Y-axis slide, and the dispensing head is connected to the Z-axis slide.

[0025] By adopting the above technical solutions, the dispensing head cleaning step ensures that the dispensing head is always in a clean state, reduces the residual colloid in the dispensing head, and improves the dispensing quality and consistency. The positioning and calibration step uses visual detection parts to accurately calibrate the position of the dispensing head, effectively reducing the accumulation of dispensing deviations caused by long-term operation, and improving the dispensing accuracy and reliability. The dispensing operation step achieves stable adsorption of the carrier through the induction valve, ensuring the accurate position of the carrier during the dispensing process, further improving the quality and efficiency of dispensing.

After dispensing, the dispensing head can be driven by the moving mechanism to contact the cleaning component. The cleaning driving source drives the cleaning component to move relative to the dispensing head, thereby cleaning the dispensing head, reducing the residual colloid in the dispensing head and ensuring the quality of subsequent dispensing operations; 3. The induction valve on the carrier is in an open state after contacting the carrier, so that the carrier is adsorbed on the induction valve, which improves the fixing effect of the carrier, reduces the displacement of the carrier during the dispensing process, and further improves the accuracy and reliability of dispensing.
