Coin Acceptor

Concept

在台灣,硬幣是一種最多人使用的東西,常見的台灣硬幣有50、10、5、1元

想要在裝置上將幣值電子化,最先想到的就是投幣機了,但是投幣機價格昂貴,因此讓我產生想用自己的方式來設計投幣裝置

In Taiwan, coins are the most used thing. Common Taiwanese coins are 50, 10, 5, 1 yuan

If I want to digitize the currency value on the device, the first thing that comes to mind is the coin-operated machine, but the coin-operated machine is expensive, so I want to design the coin-operated device in my own way

senseing

台幣的硬幣尺寸間隔2mm,因此很難利用現有的感測器去感測,例如紅外線感測器。

在這個專案中利用光敏二極體,獲取硬幣滾過感測範圍的遮掩感測器的多寡所產生的數值,以此方式讀取硬幣的大小差異

The coin size of Taiwan dollars is 2mm apart, so it is difficult to detect it with existing sensors, such as infrared sensors.

In this project, the photosensitive diode is used to obtain the value generated by the number of covered sensors that the coin rolls over the sensing range, and the size difference of the coin is read in this way

PCB layout and soldering

並且利用tinkerCad模擬電路的狀況後,並將電路輸出PCB Layout,在將PCB電路板焊接完成感測器系統

And use tinkerCad to simulate the situation of the circuit, and output the circuit to PCB Layout, and complete the sensor system after soldering the PCB circuit board

Assemble

完成後將電路板與錢道進行組裝,完成硬幣感測裝置

After completion, assemble the circuit board and the coin channel to complete the coin sensing device
