Description

Pos machine infrared touch screen

technical field

The utility model relates to the field of display technology, in particular to an infrared touch screen of a Pos machine.

Background technique

With the development of technology, the friendly human-computer interaction mode of the touch screen has been recognized and favored by the majority of users, and the touch screen has replaced the role of the mouse in many places. Pos machines are used as supermarket cash registers and ordering machine systems. Resistive touch screens were used in the past, but because the resistive touch screen has a layer of film, the light transmission of the product is not good, and the tympanic membrane phenomenon will appear after the service life is more than one year, and must be replaced. However, the existing infrared touch screen cannot be put into the shell of the POS machine, and thus cannot be used.

The above defects are worth solving.

Contents of the invention

In order to overcome the deficiencies of the existing technology, the utility model provides an infrared touch screen of a Pos machine.

The technical scheme of the utility model is as follows:

The POS machine infrared touch screen is characterized in that it includes a housing and a touch screen glass plate, a circuit board is arranged inside the housing, an infrared emitting and receiving device is provided on the circuit board, and a filter bar is provided above the housing, The touch screen glass plate is arranged above the filter strip.

Further, the casing, the circuit board and the filter strip are in a seamless frame structure.

The upper side of the circuit board is a light board, and the lower side is a circuit board.

The lamp board is provided with infrared emitting lamps and infrared receiving lamps, the infrared emitting lamps are arranged on adjacent two sides of the circuit board, and the infrared receiving lamps are arranged on the other two sides of the circuit board.

The width of the casing frame is 12-16cm.

Further, the glass plate of the touch screen is adhesively connected to the filter strip, and the filter strip is adhesively connected to the housing.

Further, the circuit board is provided with a USB connection for connecting external devices and supplying power.

According to the utility model with the above structure, its beneficial effect is that the utility model solves the problem that the infrared touch screen cannot be put into the pos machine, and because there is no film on the infrared touch screen, there is no problem of the eardrum, so that the service life is as long as 5 years. The service life of the resistive screen is more than three times that of the resistive screen, greatly increasing the service life of the touch screen and the pos machine; the utility model uses an infrared touch screen, which reduces the serious pollution of a large number of discarded resistive screens to the environment, and effectively saves organic resources; The utility model has a beautiful appearance, can reduce damage to circuit boards, and can effectively reduce the thickness of the entire touch screen at the same time.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figure 1, the utility model provides a POS machine infrared touch screen, including a housing 1 and a touch screen glass plate 2, a circuit board 4 is arranged inside the housing 1, and an infrared emitting and receiving device is arranged on the circuit board 4, and the housing A filter bar 3 is arranged above the body 1 , and a touch screen glass plate 2 is arranged above the filter bar 3 . The filter strip 3 can pass through infrared light, but the circuit board 4 inside cannot be seen by human eyes through the filter strip, which has the functions of being beautiful and protecting the circuit board 4 .

The housing 1, the circuit board 4 and the filter bar 3 are of a seamless frame structure. The upper side of the circuit board 4 is a lamp board, and the lower side is a circuit board. The lamp board is provided with an infrared emitting lamp 41 and an infrared receiving lamp 42. The emitting lamps 41 are arranged on adjacent two sides of the circuit board 4 , and the infrared receiving lamps 42 are arranged on the other two sides of the circuit board 4 .

The frame width of the casing 1 is 12-16cm. The USB wiring (not shown in the figure) on the circuit board 4 is used for connecting to a computer and supplying power.

The glass plate 2 of the touch screen is glued and connected to the filter strip 3 , and the filter strip 3 is glued and connected to the housing 1 . The overall structure of the utility model can effectively reduce the thickness of the entire touch screen, increase the service life of the touch screen and the entire pos machine, and reduce the pollution to the surrounding environment caused by frequent replacement of the resistance screen.

It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should belong to the protection scope of the appended claims of the present utility model.

The utility model patent has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the implementation of the utility model patent is not limited by the above-mentioned methods, as long as various improvements made by the method concept and technical solutions of the utility model patent are adopted, or Directly applying the ideas and technical solutions of the utility model patent to other occasions without improvement is within the protection scope of the utility model.
