Description

[Technical Field]

[0001] This utility model relates to the field of detection equipment technology, specifically an automatic oil particle size detection system. [Background Technology]

[0002] Currently, particle size analyzers on the market often require manual placement of sample vials into the sample compartment, manual locking of the pressure chamber, and then execution of the detection operation, which takes approximately 3-6 minutes. After the detection is complete, the sample vials must be manually removed, cleaning solution placed into the sample compartment, and a cleaning operation performed. These types of particle size analyzers cannot achieve automated detection and cannot continuously supply samples, thus failing to avoid the drawbacks of manual operation and waiting time. [Utility Model Content]

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing an automatic oil particle size detection system. Compared to conventional particle size detection instruments, this system can not only perform automatic detection but also automatically and continuously supply samples, saving manual operation and waiting time, thereby freeing up manpower and effectively avoiding the instability of manual operation.

[0008] Furthermore, an alarm light 16 is installed on the top of the metal frame 1. The alarm light 16 is electrically connected to the electrical cabinet 9 and is used to provide an alarm when there is a malfunction.

[0009] Furthermore, the X-axis linear module 2, Y-axis linear module 3, Z-axis linear module 4, 2D vision module three-finger electric gripper 5, and automatic particle counter 10 are all controlled by a desktop computer, and sample information and detection parameters are set through the desktop computer.

[0010] Furthermore, at least two sample trays 6 are provided, each sample tray 6 has multiple sample positions, and the sample trays 6 are fixed on the worktable 7 by the sample tray positioning assembly 8.

[0011] Furthermore, the automatic particle counter 10 is provided in two units, and the two automatic particle counters 10 alternately detect the particle size of the oil.
