Suction pen having fool-proof function

Abstract

The invention relates to the technical field of assembling devices of monitoring lenses, in particular to a suction pen having the fool-proof function. The suction pen having the fool-proof function comprises a suction pen body. The suction pen body is provided with a vacuum pipe connector and a suction end used for sucking a lens. The suction pen body is further provided with an air channel. Theair channel penetrates through the suction pen body and enables the vacuum pipe connector to communicate with the suction end. The suction end comprises a suction face used for being attached to the lens. The suction face is adapted to the arc face structure of one curved face on the lens and provided with a groove structure. The groove structure is arranged to communicate with the air channel orthe external atmosphere according to the type of the lens and the arc face structure of the suction face, so that the suction pen can only suck the lens from one curve face. The suction pen having thefool-proof function has the advantages of being simple in structure, convenient to use and capable of effectively preventing that the lens is assembled reversely.

Description

【Technical field】 [0001] The invention relates to the technical field of monitoring lens assembly equipment, in particular to a suction pen with foolproof function. 【Background technique】 [0002] Surveillance lenses are generally assembled from several group lenses, and each group lens is assembled from several parts (generally including several lenses, spacers, etc.) in sequence. During the assembly process of the group lens, it is often necessary to transfer the lens. In order to prevent the lens from getting dirty, falling, or damaging the lens, a suction pen is usually used to assist in the transfer of the lens. Such as figure 1 , the common lens includes two curved surfaces (front S1 and reverse S2), usually the curvature radii of these two curved surfaces are different; as figure 2 and image 3 As shown, the existing suction pen includes a suction pen body 20, the suction pen body 20 is provided with a vacuum tube interface 21, an adsorption end 22 for absorbing l...

AI Technical Summary

Problems solved by technology

like figure 1 , the common lens includes two curved surfaces (front S1 and reverse S2), usually the curvature radii of these two curved surfaces are different; as figure 2 and image 3 As shown, the existing suction pen includes a suction pen body 20, the suction pen body 20 is provided with a vacuum tube interface 21, an adsorption end 22 for absorbing lenses and runs through the suction pen body 20 and communicates with the vacuum tube interface 21 and the absorption end 22 When the suction end 22 is attached to the front S1 or the back S2 of the lens, an effective closed space can be formed. Therefore, this kind of suction pen can be used to suck up such lenses with different radii of curvature from the front S1 or the back S2. Curved lenses are likely to cause workers or machines to assemble the lenses backwards during the assembly process, resulting in bad group lenses; and if relying on workers to check the front and back of the lenses before assembly, it is easy to misjudge or miss inspections, or if Adding lens front and back recognition equipment is relatively expensive
