Abstract
The utility model relates to a wave -soldering cooling fan detection mechanism directly perceived, it is including observing the fan and observing fan bracket, observe fan bracket fixed mounting in cooling fan top, observe the fan and rotate installation observation fan bracket, observe the refrigeration fan top that the fan is located the cooling fan, observe the fan and rotate the top of installing at the refrigeration fan through observing fan bracket, rotate the during operation when the refrigeration fan, because the convection current effect of air, it also and then rotates to observe the fan, thereby whether intuitive judgment refrigeration fan normally works, and needn't closely survey, practicality directly perceived, additionally, the screw passes the double -H groove weld shape groove of observing fan bracket, the axiality of adjustable observation fan and refrigeration fan, it is fan -driving to do benefit to the quilt refrigeration of observing the fan better.
Description
Technical field
The utility model relates to wave soldering temperature-dropping fan, is specifically related to the mechanism of visual inspection wave soldering temperature-dropping fan working state.
Background technique
Wave soldering is for the more common a kind of technique of soldered circuit board.Can put in temperature-dropping fan through the circuit board of wave soldering and cool fast, so that postorder processing.Temperature-dropping fan is provided with multiple refrigerating fan, and circuit board is placed on below refrigerating fan, circuit board cooling under the air drafting effect of refrigerating fan.General in order to prevent foreign matter from entering refrigerating fan, last layer protective housing can be overlapped at refrigerating fan skin.Although protective housing can play the effect of protection, whether the operator simultaneously hindered observes refrigerating fan has rotation.Know whether refrigerating fan has work in order to clear, operator can only closely observe, not intuitively, convenient.
Model utility content
In order to solve the problem, the utility model provides a kind of feeler mechanism of energy visual inspection temperature-dropping fan working state, and concrete technological scheme is as follows:
Wave soldering temperature-dropping fan visual inspection mechanism, it comprises observes fan and observes blower tray, observes blower tray and is fixedly mounted on above temperature-dropping fan, observes fan turns and installs observation blower tray and be positioned at above the refrigerating fan of temperature-dropping fan.
Preferably, the refrigerating fan concentric shafts of described observation fan and temperature-dropping fan.
Preferably, described observation blower tray is provided with the dual U-shaped groove of position adjustable.
Preferably, described observation fan comprises impeller and rotating shaft, and impeller is fixedly connected with rotating shaft, and axis of rotation is installed on observation blower tray.
Preferably, the flabellum number of described impeller is 3.
The beneficial effects of the utility model: observe fan is rotatably installed in refrigerating fan top by observing blower tray, when refrigerating fan rotation work, due to the convection action of air, observe fan and also and then rotate, thus whether intuitive judgment refrigerating fan normally works, and need not closely observe, practicality directly perceived, in addition, screw is through the dual U-shaped groove observing blower tray, the coaxality of adjustable observation fan and refrigerating fan, is beneficial to and observes the better cooled fans drive of fan.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model;
Fig. 2 is exploded view of the present utility model;
Fig. 3 is embodiment schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As depicted in figs. 1 and 2, wave soldering temperature-dropping fan visual inspection mechanism, it comprises observes fan 1 and observes blower tray 2, observes the dual U-shaped groove that blower tray 2 is provided with position adjustable, and screw is fixedly mounted on above temperature-dropping fan observing blower tray 2 through dual U-shaped groove.Observe fan 1 and comprise impeller 12 and rotating shaft 11, impeller 12 is fixedly connected with rotating shaft 11, and rotating shaft 11 is rotated to be installed on and observed blower tray 2, and impeller 12 is positioned at above the refrigerating fan 5 of temperature-dropping fan 4, and refrigerating fan 5 skin is provided with one deck protective housing (not marking).By observing the dual U-shaped groove of blower tray 2, observation fan 1 being adjusted to concentric shafts with refrigerating fan 5, being beneficial to refrigerating fan 5 and driving observation fan 1 to rotate.
During use, as shown in Figure 3, need the circuit board 6 of cooling, place on a moving belt and be positioned at temperature-dropping fan 4, temperature-dropping fan 4 is arranged on above line belt, temperature-dropping fan 4 is provided with multiple refrigerating fan 5, be provided with an observation fan 1 above each refrigerating fan 5, refrigerating fan 5 starts rotary work, cooling circuit board 6, when refrigerating fan 5 works, due to the convection action of air, the cooled fan 5 of impeller 12 observing fan 1 drives and rotates, and user is by observing the rotation of impeller 12, thus judge whether refrigerating fan 5 normally works, intuitively very convenient.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
