Description

Simple glass automatic cleaning device

technical field

The utility model relates to a simple glass automatic cleaning device, which belongs to the field of glass cleaning.

Background technique

Now glass has been widely used in the field of construction, and it is divided into large-area use (such as modern building exterior walls) and small-area use (such as windows in homes). At present, glass cleaning is mostly done manually. People are constantly pursuing automation, so people are more willing to lay pipelines in advance in building design to develop large-scale cleaning systems. And in places where glass is used on a small scale, such as families, although some products are launched on the market, they are generally expensive and cannot be widely used. The cleaning of household high-rise glass pays more attention to the characteristics of simplicity, small size and low cost of the cleaning device.

In this example,

Select the length of the rocker as 150mm, the length of the frame as 250mm, the swing angle of the rocker as 90 degrees, and the extreme angle as 20 degrees. The lengths of the other two rods calculated by CAD drawing are: connecting rod: 276mm; crank: 96mm.

The choice of motor is as follows:

According to the actual test, the force required to wipe the glass is about 10N, which is evenly distributed on the scrubbing rod. Assuming that the glass is 50cmX50cm, the longest rocker is about 70cm. The required working torque by the torque formula is:

$\mathrm{<span\; class="notranslate">\; m</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; f</span>}\mathrm{<span\; class="notranslate">\; L</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 10</span>}<span\; class="notranslate">\; \&times;</span>\frac{\mathrm{<span\; class="notranslate">\; 70</span>}}{\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; \&times;</span>\mathrm{<span\; class="notranslate">\; 100</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 3.5</span>}\mathrm{<span\; class="notranslate">\; N</span>}<span\; class="notranslate">\; .</span>\mathrm{<span\; class="notranslate">\; m</span>}$

The design scrubbing speed is 6s for one cleaning process, then the required crank speed is:

n＝60÷6＝10r/min

The required power is then:

$\mathrm{<span\; class="notranslate">\; P</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; m</span>}\mathrm{<span\; class="notranslate">\; \&omega;</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 3.5</span>}<span\; class="notranslate">\; \&times;</span>\frac{\mathrm{<span\; class="notranslate">\; 10</span>}<span\; class="notranslate">\; \&times;</span>\mathrm{<span\; class="notranslate">\; 2</span>}\mathrm{<span\; class="notranslate">\; p</span>}\mathrm{<span\; class="notranslate">\; i</span>}}{\mathrm{<span\; class="notranslate">\; 60</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 3.665</span>}\mathrm{<span\; class="notranslate">\; w</span>}$

Considering the possible friction loss and efficiency loss in the middle, the final power is selected as 5w.

After the comparison of the same kind, the selection of the motor is as follows:

775 motor flat shaft D-type trimming shaft, its parameters are as follows: rated voltage: 12V, no-load current: 0.27A, locked-rotor current: 3.25A, no-load speed: 4500 rpm, motor step height: 4.5mm, motor Step diameter: 17.5mm, shaft length: 16mm (shaft length above the level of the step), shaft diameter: 5mm shaft (cut edge 1.5mm, trim length 13mm), motor diameter: 42mm, motor length: 66.5mm, motor tail Step height: about 7mm, motor tail shaft length: about 4.5mm, installation hole pitch: about 29mm, installation hole diameter: M4 screw, motor weight: 350g.

Gear ratio calculation:

The motor speed was selected up to 4500 RPM, and the design called for a final speed of 10 RPM. Therefore, the total transmission ratio is about 450. The motor itself is equipped with a 1M10 tooth gear. In order to reduce the number of transmission stages and improve transmission efficiency, 1M100 teeth are used as the large gear for deceleration. The pinion coaxial with the bull gear selects a 1M15 tooth gear.

So: i total = 450

i1=10

100/15=i2=i3=...

It is calculated that a total of three stages of reduction are required, and the final drive ratio is:

Basically satisfy i total = 450, the calculation is completed.

According to the above calculations, it can be known that the power required by the cleaning device in this embodiment is not very high, and the transmission accuracy is not high, and the upper limit of the selected motor power is not high. If a relatively heavy standard gear is selected, the final transmission power will be insufficient. . Therefore, the plastic nylon gear was finally selected as the transmission gear. Plastic nylon spur gears, available in two forms with bosses and without bosses. The advantage is that the weight is lighter, the rotational inertia is small, and the power loss in the transmission process is small. The disadvantage is that the strength of the material is not high, it cannot withstand high-power transmission, and the installation is easy to deviate.

The above description of the embodiments is for those of ordinary skill in the technical field to understand and use the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments, and apply the general principles described here to other embodiments without creative effort. Therefore, the utility model is not limited to the above-mentioned embodiments, and improvements and modifications made by those skilled in the art according to the disclosure of the utility model without departing from the category of the utility model should be within the protection scope of the utility model.
