Description
Technical field
The utility model relates to a kind of light shield, especially relates to a kind of light shield being applied to Renminbi cleaning-sorting machine counter tube.
Background technology
Counter is requisite parts in Renminbi cleaning-sorting machine or paper money counter, and it is installed on and send among paper money passage, as counting assembly, when bill send circulate fast in paper money passage time, bill is counted and adds up.
The counter of prior art is generally built in and send in paper money passage, and adopt infrared transmitting tube to launch infrared light beam covering and send paper money passage, when bill is through infrared light beam, feedback signal is sent to PCB and carries out computing by infrared transmitting tube.In the middle of actual use procedure, infrared transmitting tube is exposed to and send paper money channel content easily produce the accumulation of dust and then affect the transmitting of infrared beam, and the bill that infrared transmitting tube contact simultaneously transmits fast also easily produces wearing and tearing, causes the damage of infrared transmitting tube.
Utility model content
In order to solve the problem, the utility model provides a kind of light shield being applied to Renminbi cleaning-sorting machine counter tube.
The technical solution adopted in the utility model is as follows:
A kind of counter tube light shield, described hormone pipe light shield comprises counter tube body and light shield, described counter tube comprises infrared emission tube and PCB, described light shield is cylinder type hollow body, described light shield top is provided with light-conductive hole, and described light shield side is connected with fixture, and described infrared emission tube is installed on PCB, described light shield is socketed on infrared emission tube, and described fixture is connected with PCB.
Further, described light shield and fixture one-body molded.
Further, described fixture is provided with through hole of tightening up a screw, described PCB arranges lower screw through-hole respectively, described in the tighten up a screw axle center of through hole and lower screw through-hole be positioned in same level.
Further, described light-conductive hole is half closing cylinder.
Further, described light shield and fixture adopt transparent material to make.
Further, described infrared emission tube has 2 pins, described PCB is provided with two pin access ports, and pin and pin access port are welded to connect.The utility model compared with the existing technology, has the following advantages and beneficial effect:
A kind of counter tube light shield that the utility model provides, described counter tube comprises infrared emission tube, PCB, described light shield is cylinder type hollow body, described light shield top is provided with light-conductive hole, described light shield side is connected with fixture, described infrared emission tube is installed on PCB, and described light shield is socketed on infrared emission tube, and described fixture is connected with PCB; This counter tube light shield adopts modular design, can independently install and replace, and conduction is amplifying optical signals also, the short circuit that protection counter tube is not subject to extraneous contact and produces and destruction.
Accompanying drawing explanation

Reference numeral: light shield 1, PCB 2, infrared emission tube 3, light-conductive hole 4, through hole 5 of tightening up a screw, fixture 6, lower screw through-hole 7, pin 8, pin access port 9.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The counter tube light shield that the utility model provides, is applied to the bank note transfer passage of paper money counter or cleaning-sorting machine, and conduction is amplifying optical signals also, the short circuit that protection counter tube is not subject to extraneous contact and produces and destruction.
See shown in Fig. 1 to Fig. 3, a kind of counter tube light shield of the present utility model comprises counter tube body and light shield 1.Institute's counter tube comprises infrared emission tube 3 and PCB 2, and described infrared emission tube 3 sends infrared signal, and PCB 2 effect is to amplify and conduction infrared signal.Light shield 1 is cylinder type hollow body, light shield 1 top is provided with light-conductive hole 4, light shield 1 side is connected with fixture 6, the effect of fixture 6 to be light shield 1 to be fixedly installed in PCB 2 in the middle of assembling process, infrared emission tube 3 is installed on PCB 2, light shield 1 is socketed on infrared emission tube 3, and fixture 6 is connected with PCB 2 to install fixing light shield 1.
Further, light shield 1 and fixture are adopted 6 and are used one-body molded design, ensure that the global consistency of light shield 1.Light shield 1 and fixture 6 all adopt transparent material to make simultaneously, ensure that the light transmission of light shield 1 and fixture 6.
Further, be respectively arranged with tighten up a screw through hole 5 and lower screw through-hole 7 on described fixture 6 He in PCB 2, the axle center of described upper and lower screw through-hole is positioned in same level.By upper and lower screw through-hole, light shield 1 and PCB 2 are connected and fixed by screw, complete the assembling of counter tube and light shield 1.
Further, light-conductive hole 4 is half closing cylinder, its role is to the infrared ray converging infrared emission tube transmitting, ensures that infrared ray accurately can locate the bill in moving.
Further, described infrared emission tube 3 has 2 pins 8, described PCB 1 is provided with two pin access ports 9, and pin 8 and the pin access port 9 of described infrared emission tube are welded to connect.
This counter tube light shield adopts modular design, can independently install and replace, and conduction is amplifying optical signals also, the short circuit that protection counter tube is not subject to extraneous contact and produces and destruction.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
