Detailed Description
Referring to fig. 1 or 8, the present invention provides a detecting mechanism 100 for detecting whether a detection parameter of a product 20 is within a qualified range, so as to determine whether the product 20 is qualified. The detection parameters may be the verticality, circular run-out, etc. of the product 20. The detection mechanism 100 includes a first detection assembly 12, a second detection assembly 14, and a reminder assembly 60. The first detecting member 12 has a detecting hole 52. The second sensing assembly 14 is disposed opposite the sensing aperture 52. The reminder assembly 60 is electrically connected to the first detecting assembly 12 and the second detecting assembly 14. The second detecting component 14 and the detecting hole 52 are both used for detecting the contact condition with the product 20, so as to control the working state of the reminding component 60 according to the contact condition.
The contact condition comprises contact and non-contact, when the second detection assembly 14 and the detection hole 52 are both contacted with the product, the first detection assembly 12 and the second detection assembly 14 can be conducted, and when the second detection assembly 14 and the detection hole 52 are both not contacted with the product, the first detection assembly 12 and the second detection assembly 14 are powered off; correspondingly, the working state includes a reminding state and a non-reminding state, specifically, when the first detection assembly 12 and the second detection assembly 14 are conducted, the reminding assembly 60 is powered on, and the reminding assembly 60 enters the reminding state; when the first detection component 12 and the second detection component 14 lose power, the reminding component 60 loses power, and the reminding component 60 enters a non-reminding state. The reminding component 60 is in the reminding state to indicate that the product 20 is qualified, and the reminding component 60 is in the non-reminding state to indicate that the product 20 is unqualified. For example, when detecting the size of the product 20 or the tolerance of the circular runout, if the size of the product 20 matches the size of the detecting hole 52, i.e. the product 20 contacts the detecting hole 52, the condition that the reminding assembly 60 is in the reminding state can be defined as that the product 20 is qualified; if the size of the product 20 does not match the size of the inspection hole 52, i.e. the product 20 does not contact the inspection hole 52, the reminding component 60 being in the reminding state can be defined as that the product 20 is unqualified. In other embodiments, the product 20 may be defined as not qualified when the reminder component 60 is in the reminder state and the product 20 is defined as not qualified when the reminder component 60 is in the non-reminder state. For example, in detecting the verticality tolerance of the product 20, if the verticality of the product 20 is not within the allowable verticality tolerance of the detecting hole 52, i.e. the product 20 is in contact with the detecting hole 52, the condition that the reminding component 60 is in the reminding state can be defined as that the product 20 is unqualified; if the verticality of the product 20 is within the tolerance of the allowable verticality of the detecting hole 52, i.e. the product 20 is not in contact with the detecting hole 52, the condition that the reminding component 60 is in the reminding state can be defined as that the product 20 is qualified.
The product 20 may be a metal product with conductive properties, and when the metal product is inserted into and contacts the detecting hole 52 and abuts against the second detecting component 14, the metal product, the first detecting component 12, and the reminding component 60 powered by the power source 72 (described below) are sequentially conducted to form a conducting loop.
In other embodiments, the product 20 may also be a non-metal product, such as the product 20 made of ceramic or plastic, the first detecting component 12 and the second detecting component 14 are respectively provided with a first switch and a second switch electrically connected to the reminding component 60, when the product 20 is inserted into and contacts the detecting hole 52, the first switch is turned on, when the product 20 abuts against the second detecting component 14, the second switch is turned on, and at this time, the second switch, the first switch and the reminding component 60 powered by the power source 72 are sequentially turned on to form a conducting loop. The first switch and the second switch can be pressure switches and can also be proximity switches.
For convenience of understanding, the present embodiment is explained as the product 20 is qualified to be detected to be perpendicular, as shown in fig. 7, the product 20 includes a base portion 21 and a portion to be detected 22, and the base portion 21 is vertically connected to the portion to be detected 22.
