It should be noted that the direction of the aforementioned downward pressure may be the thickness direction of the workpiece 5 to be detected, or the aforementioned downward pressure at least has a component force in the thickness direction of the workpiece 5 to be detected, and preferably, as shown in fig. 3, the friction head 12 may apply the downward pressure along the thickness direction of the workpiece 5 to be detected to the workpiece 5 to be detected, so as to ensure a better detection effect, and avoid wasting the force.

In addition, the maximum friction force which can be borne by the surface coating of the workpiece 5 to be detected can be measured and calculated by means of the pressure detection mechanism 4, specifically, the mode of the downward pressure of the friction head 12 acting on the workpiece 5 to be detected can be changed, and then the coating process can be reversely deduced and improved according to the coating bonding strength, so that the purpose of perfecting the coating process is finally achieved, and the bonding strength of the coating at each position on the workpiece 5 to be detected formed by adopting more perfected coating work is ensured to be higher.
