Abstract
Disclosed is a photoelectric sensor with a LED counter, which replaces the chip element in prior art with the LED chip. The utility model is composed of a counting gear, an infrared transmitter and an infrared receiver, wherein, the infrared transmitter and the infrared receiver are respectively composed of an infrared transmitting chip and an infrared receiving chip prearranged on a printed circuit board connecting with circuit. The printed circuit boards prearranged with LED chips are respectively fixed with a shade disk; a narrow optical channel is arranged on the shade disk, facing the LED chip, in order to further enhance the anti-visible light ability. The optical channel is also be filled with mediums which has strong resistance to visible light and is easy for infrared light to penetrate through. The utility model which has the advantages of small size, lower cost, high accuracy and strong anti-visible light ability, is applicable to various counters with different standards.
Description
Affiliated technical field
The utility model relates to a kind of photoelectric sensor, concretely, is the LED photoelectric sensor that uses in a kind of counter.
Background technology
Counter is widely used among all trades and professions and the people's daily life, for example in water meter, ammeter, the gas meter.Utilize the counter of LED fabrication techniques, prior art is to adopt paster infrared emission tube and patch red outside line receiving tube to make.There is the shortcoming that volume is big, precision is relatively poor and the anti-visible-light ability is relatively poor in this product.Each of counter, can be divided into some groups, for decade counter, each can be divided into five groups, form by infrared transmitter, counting gear and infrared receiver for every group, have the optical channel of the different shape that is applicable to decimal system counting on the counting gear, for sake of convenience, we might as well claim that each group in these five groups is a LED photoelectric sensor.
Summary of the invention
In order to overcome the shortcoming that the existing existing volume of LED photoelectric sensor is big, precision is relatively poor, the anti-visible-light ability is relatively poor, the utility model provides a kind of counter that a kind of volume is littler, precision is higher, the anti-visible-light ability is stronger LED photoelectric sensor.
The technical scheme that its technical matters that solves the utility model adopts is: with led chip is paster infrared emission tube and the infrared receiver tube that infrared chip and infrared ray receiving chip replace available technology adopting.Like this, said LED photoelectric sensor is made up of counting gear, infrared transmitter and infrared receiver, infrared transmitter and infrared receiver lay respectively at the both sides of counting gear, infrared transmitter and infrared receiver are respectively with infrared chip and infrared ray receiving chip, be preset on the corresponding printed circuit board (PCB), be connected with circuit by printed circuit board (PCB) and constitute.Preset on the printed circuit board (PCB) of chip, respectively be fixed with a blanking disc, on the blanking disc over against the position of chip, have a narrow cylindrical optical channel, the pairing optical channel equal and opposite in direction of infrared transmitter and infrared receiver, the dead in line of two optical channels, can fill in optical channel in case of necessity has the effect of certain resistance shelves and is beneficial to the medium that infrared ray passes through visible light, to strengthen the ability of anti-visible-light.
The beneficial effects of the utility model are: the volume of product is littler, cost is lower, precision is higher, the anti-visible-light ability is strong.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a LED photoelectric sensor structural section, also is an embodiment of the present utility model.
1a. printed circuit board (PCB) among the figure, 1b. printed circuit board (PCB), 2. blanking disc, 3. infrared chip, 4. infrared ray receiving chip, 5. counting gear.
Embodiment
In Fig. 1, the both sides of counting gear 5 are fixed with printed circuit board (PCB) 1a and 1b respectively, relevant position on printed circuit board (PCB) 1a, preset infrared chip 3, relevant position on printed circuit board (PCB) 1b, preset infrared ray receiving chip 4, printed circuit board (PCB) 1a is connected with external circuit respectively with 1b, printed circuit board (PCB) 1a and infrared chip 3 are formed infrared transmitter, printed circuit board (PCB) 1b and infrared ray receiving chip 4 are formed infrared receiver, on printed circuit board (PCB) 1a and 1b, be fixed with blanking disc 2 respectively, blanking disc and printed circuit board (PCB) are close to, respectively have a narrow columniform hole on the blanking disc over against the position of chip as optical channel, the dead in line of two optical channel equal and opposite in directions and two optical channels.The infrared ray that sent of infrared chip 3 can only spread out of from the optical channel that connects printed circuit board (PCB) 1a like this, passes the optical channel on the counting gear, enters the optical channel that connects printed circuit board (PCB) 1b and arrives infrared ray receiving chip 4.The break-make of infrared ray receiving chip is controlled by counting gear in other words.Five such LED photoelectric sensors match and just can finish the counting work of one of decade counter, and it can be the electronic data of zero defect by conversion of photoelectric sensor with data shown on the counting gear.
Obviously, owing to replaced the surface mount elements that uses in the prior art with led chip, the volume of counter is greatly reduced: because blanking disc and led chip are close to and have been covered led chip, avoided using that surface mount elements brought because of the infrared ray scattering of light, the interference that diffuse reflection caused, thereby precision is higher; Because blanking disc has covered the infrared ray receiving chip, visible light possibility Chuan Ba weakens greatly to the amount of this chip, thereby has strengthened the ability of anti-visible-light.In addition, can also fill in the optical channel of blanking disc has certain barrier effect and is beneficial to the material that infrared ray passes through visible light, with the ability of further enhancing anti-visible-light.
According to this principle, change the quantity of LED photoelectric sensor and quantity and the relative position that changes optical channel on the counting gear, the utility model is just applicable to the counter of different systems.
Claims (2)
1, a kind of counter LED photoelectric sensor, by counting gear, infrared transmitter and infrared receiver are formed, infrared transmitter and infrared receiver lay respectively at the both sides of counting gear, it is characterized in that said infrared transmitter and infrared receiver are respectively with infrared chip and infrared ray receiving chip, be preset on the corresponding printed circuit board (PCB), be connected with circuit by printed circuit board (PCB) and constitute, preset on the printed circuit board (PCB) of led chip and respectively be fixed with a blanking disc, on the blanking disc over against the position of chip, have a narrow cylindrical optical channel, the dead in line of two optical channels, and equal and opposite in direction.
2, counter LED photoelectric sensor as claimed in claim 1 is characterized in that being filled with in the optical channel of said blanking disc visible light is had the effect of strong resistance shelves and is beneficial to the medium that infrared ray passes through.
