Abstract
The utility model discloses a screen detector of filter screen, which is characterized in that light is emitted from a point light source 101, because the point light source 101 is at the focus of a convex lens 102, the light transmitting the convex lens 102 is converted into parallel light 109, the parallel light 109 passes through a tooling 103 and a product (the filter screen) to form parallel light 110, part of the parallel light 110 is reflected by the tooling 103 and the product (the filter screen), and the parallel light 110 passes through a convex lens 105 to be converged on the focus of the convex lens 105. In the utility model, a sensitization element 106 is arranged on the focus of the convex lens 105, at this time, the parallel light 110 is converged on the sensitization element 106, an electric signal is transmitted to a comparative judgement device 107 through the sensitization element, the electric signal and a preset value are compared by the comparative judgement device 107, whether the light transmission amount reaches the preset requirements or not is judged, then a result is transmitted to a PLC (Programmable Logic Controller) 108, and PLC 108 controls the tooling 103 to discharge unqualified products.
Description
Technical field
The utility model relates to a kind of screen pack mesh machines, and the detection that is used for screen pack mesh size, transmittance and permeability rate of indefiniteness is applied to detect the intake pipe of washing machine screen pack especially.Belong to the checkout equipment field.
Background technology
When screen pack of selling in the market and screen pack goods were applied to filter liquide or IMPURITIES IN, screen pack can form a kind of resistance to liquid or the gas that sees through screen pack.At this resistance of the constant maintenance screen pack of needs and when detecting screen pack; Present method is to measure with the flowmeter of liquid or gas; But under many circumstances,, can't adopt flowmeter to measure the flow of liquid or gas such as open screen pack and goods thereof.And the method measurement of adopting flowmeter can receive the influence of several factors, and measurement result is not very accurately.
Summary of the invention
For solving existing problem in the above-mentioned prior art, the utility model provides a kind of screen pack mesh machines, and it is simple in structure, and is easy for installation, and test result is stable.
The technical scheme that the utility model adopted is:
Utilize the characteristic of rectilinear propagation, reflection, refraction and the transmission of light, detect the intensity of the light that sees through filter mesh, convert mesh size, transmittance and the permeability rate index of screen pack into.
A kind of screen pack mesh machines comprises pointolite 101, optical male lens 102, frock 103, optical male lens 105, photo-sensitive cell 106, compares to determine device 107, PLC controller 108.
Aforesaid a kind of screen pack mesh machines is characterized in that: in product (screen pack) 104 upper fixed optical male lens 102 are arranged, on focus above the optical male lens 102, be fixed with pointolite 101.Below at product (screen pack) 104 is fixed with optical male lens 105; Focus is fixed with photo-sensitive cell 106 below optical male lens 102; Photo-sensitive cell compares to determine device 107 through being wired to; Compare to determine device 107 and be connected to PLC controller 108, PLC controller 108 is connected with frock 103.Product (screen pack) 104 is placed on the frock 103.
Description of drawings
In the following explanation of preferred embodiment, following accompanying drawing is carried out reference.
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description.
As shown in Figure 1, the comprising pointolite 101, optical male lens 102, frock 103, optical male lens 105, photo-sensitive cell 106, compare to determine device 107, PLC controller 108 of a kind of screen pack mesh machines indefiniteness.
Aforesaid a kind of screen pack mesh machines is characterized in that: in product (screen pack) 104 upper fixed optical male lens 102 are arranged, on focus above the optical male lens 102, be fixed with pointolite 101.Below at product (screen pack) 104 is fixed with optical male lens 105; Focus is fixed with photo-sensitive cell 106 below optical male lens 102; Photo-sensitive cell compares to determine device 107 through being wired to; Compare to determine device 107 and be connected to PLC controller 108, the running of PLC controller 108 control frocks 103.Product (screen pack) 104 is placed on the frock 103.
The principle of work of the utility model is: light is sent by pointolite 101; Because pointolite 101 is on the focus of convex lens 102; So see through light change changing into the directional light 109 of convex lens 102; Directional light 109 passes frock 103 and product (screen pack) 104, and part is formed directional light 110 by frock 103 and product (screen pack) 104 reflections.Directional light 110 passes convex lens 105 backs and is converged on its focus.Because on the focus of convex lens 105, be provided with photo-sensitive cell 106.This moment, directional light 110 was concentrated on the photo-sensitive cell 106.Thereby photo-sensitive cell 106 is converted into electric signal to light intensity signal.Electric signal is transferred to from photo-sensitive cell and compares to determine on the device 107.Compare to determine 107 pairs of electric signal of device and compare, judge whether reach predetermined requirement, the output result of determination is given PLC controller 108 if seeing through light quantity with setting value before.PLC controller 108 is according to result of determination, and control frock 103 is discharged underproof product.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
