Description

The on-line measuring device using in fins set poling process

Technical field

The utility model relates to air-conditioning condenser manufacture field, particularly the online fault test set in fins set poling technique.

Background technology

Condenser in air-conditioning comprises fins set, has copper pipe in fins set, at present, is generally that manual operations is inserted copper pipe in fins set, and production efficiency is low.But manual poling also has certain advantage: in poling process, when copper pipe and fin generation obstruction, manually can be easy to failure judgement, and send copper pipe to process by repeatedly drawing.

The applicant's the equipment and process > > (application number: 201310045185.3) disclose equipment and the method that realizes automatic tube-penetrating using in first to file < < condenser fin group poling operation, but in technical process, situation about fins set being backed down if there is copper pipe top, does not also have the means that detect and process.

Summary of the invention

The purpose of this utility model is to provide a kind of device, in poling technical process, detects online above-mentioned operating mode, for further processing foundation is provided.

For achieving the above object, the technical solution adopted in the utility model is: the on-line measuring device using in fins set poling process, use photoelectric sensor, key is: column light source is arranged on fins set one side, the sensitization column of fixing a plurality of photoelectric cells is arranged on the position of fins set opposite side corresponding light source, and photoelectric cell connects control appliance.

If poling process is normally carried out, because the fin interval in fins set is very little, light can not pass fins set, or transit dose is very little, and the undercapacity of light is to allow photoelectric cell produce action, and poling technique is normally carried out.

The outer wall of copper pipe is very smooth, and after copper pipe top is smoothly through the hole on fin, the aft section of copper pipe also can be inserted smoothly, only has copper pipe top to clash with fin.When fins set is backed down on copper pipe top:

Preferred version one: strip source of parallel light is arranged between two holes of fins set, and light is not blocked by copper pipe, arrives photoelectric cell by the gap between the fin being backed down, and light intensity is enough large, makes photoelectric cell action, sends signal to control appliance.

Preferred version two: use cambered surface source of parallel light, photoelectric cell is arranged on fins set opposite side, and light is not by the hole of fins set, not that is to say and blocked by copper pipe, arrive photoelectric cell, light intensity is enough large, make photoelectric cell action, send signal to control appliance.

The technical scheme of using the utility model to provide, can be in automatic tube-penetrating process, and real-time online detection failure situation is also sent signal, for further processing foundation is provided, improves the reliability of technique.

Wherein, the 1st, fins set, the 2nd, copper pipe, the 3rd, column light source, 3-1 is the column light source that produces strip directional light, and 3-2 is the column light source that produces bar cambered surface directional light, the 4th, and sensitization column, 4-1 is the photoelectric cell on sensitization column, the 5th, control appliance, the 6th, the hole that copper pipe backs down in fins set, the 7th, the parallel rays that column light source sends, 7-1 is the parallel rays that sees through hole 6, the 8th, and the line between column light source and photoelectric cell 4-1.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, when copper pipe 2 smoothly penetrates the hole of fins set 1, fin is indeformable, referring to Fig. 2, when copper pipe 2 tops are hindered, the fin in fins set 1 can be backed down, and forms a hole 6.

Referring to Fig. 3 and Fig. 4, column light source 3-1 or 3-2 are arranged on fins set 1 one sides, and the sensitization column 4 of fixing a plurality of photoelectric cell 4-1 is arranged on the position of fins set 1 opposite side corresponding light source, and photoelectric cell 4-1 connects control appliance 5.

Embodiment 1, referring to Fig. 3, use the column light source 3-1 that produces strip directional light, the quantity of sensitization column 4 is identical with light source 3-1 quantity, be one-to-one relationship, the height of light source 3-1 and fins set 1 is identical or be greater than the height of fins set 1, and light source 3-1 position is between two holes of fins set, both the line between light source 3-1 and corresponding sensitization column 4, between two holes of fins set, can guarantee that light was not blocked by copper pipe 2 like this.In order to guarantee the accuracy of equipment, light source 3-1 is all set between the hole of every two groups of fins set.Because light source 3-1 produces strip source of parallel light, so the light that light source 3-1 sends only may be received and can not exert an influence to Other Devices 4-1 by the photoelectric cell 4-1 on the sensitization column 4 on opposite.

Column light source 3-1 can be used the matrix shell of closing in, built-in light source, and indentation limitations light source, can send strip directional light.

Embodiment 2, referring to Fig. 4, use the column light source 3-2 that produces cambered surface directional light, the height of light source 3-2 and fins set 1 is identical or be greater than the height of fins set 1, light source 3-2 and and photoelectric cell 4-1 between line 8 by the hole in fins set 1, can guarantee that like this light does not arrive photoelectric cell 4-1 by the hole of fins set 1.

Column light source 3-2 can be used matrix shell, built-in light source, and indentation limitations light source, can send cambered surface directional light, covers fins set 1.

Referring to Fig. 5, when copper pipe 2 penetrates the hole of fins set 1 smoothly, because the fin interval in fins set 1 is very little, light 7 can not pass fins set 1, or transit dose is very little, set the sensitivity of photoelectric cell 4-1, make now light intensity be not enough to allow photoelectric cell 4-1 produce action, poling technique is normally carried out.

Referring to Fig. 6, when copper pipe 2 tops are hindered, fin in fins set 1 can be backed down, form a hole 6, now, column light source 3(comprises column light source 3-1 or 3-2) the light 7-1 that sends can see through the photoelectric cell 4-1 that hole 6 arrives corresponding aperture 6 positions, be subject to the photoelectric cell 4-1 of light to produce action, signal is passed to control appliance 5, and control appliance 5, according to the position that action photoelectric cell 4-1 occurs, is controlled relevant device and is carried out troubleshooting.

For accurate detection failure, on sensitization column 4, the spacing of photoelectric cell 4-1 should be less than 2.5cm, and the less detection effect of spacing is better.In above-described embodiment, photoelectric cell 4-1 is used photodiode.

In embodiment 1, light source 3-1 is all set between the hole of every two groups of fins set, be extreme case here, in the situation that accuracy of detection can guarantee, can suitably reduce the quantity of light source 3-1.

In Fig. 4, only provided a light source 3-2, in realization, can arrange a plurality of.

The photodiode using in embodiment is just for technical scheme is described, in realization, photoelectric cell 4-1 is not limited to use photodiode.

Although the utility model is limited in poling technique and uses, at other, relate in the technical process of fins set, also can use the technical program.
