Self-inspection laminar flow workbench

The invention discloses a self-inspection laminar flow workbench. The self-inspection laminar flow workbench comprises a workbench body, an air outlet is formed in the front end of the workbench body, a fan is arranged at the bottom of the workbench body, the air outlet is connected with the fan through a pipeline, a dust particle detection device is arranged at the rear end of the workbench body, a dust filtering device is arranged at the rear end of the dust particle detection device, a control module is further arranged inside the dust particle detection device, and the control module is connected with the fan through a circuit. Dust on a workpiece is blown into the dust particle detection device through the air outlet of the workbench, the dust particle detection device feeds detected information back to the control module, and then the control module controls and adjusts the size of the air volume of the fan till the fan stops working, that is to say, the cleanliness of the workpiece surface is higher.
