Description

Technical Field

[0001] This utility model relates to the field of automatic control of vending machines, and in particular to an infrared sensor false triggering structure suitable for vending machines. Background Technology

[0002] Vending machines have become dedicated sales counters for various goods. They use internal automated mechanical structures to dispense items after customers pay, thus replacing manual labor. However, errors can easily occur during the operation of these automated mechanical structures, some due to programming issues and others due to signal problems. Signal problems often stem from erroneous signals from sensors. For infrared sensors, the primary source of erroneous signals is external light sources. Therefore, it is necessary to control these errors in the product design of vending machines to reduce their occurrence, improve their stability, and provide users with better service. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a false triggering structure for infrared sensors in vending machines, which reduces the occurrence of erroneous actions by infrared sensors.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An infrared sensor false triggering structure suitable for vending machines includes a component unit on which an infrared sensor is installed, and a light source unit disposed close to the component unit, characterized in that:

[0006] The sensing direction of the infrared sensor is distributed in the same direction as the illumination direction of the light source unit, or there is an angle between the two, and the angle is an acute angle.

[0007] The component unit is provided with at least two sets of working positions for installing the infrared sensor, and the infrared sensor is installed in at least one set of the working positions.

[0008] The work positions include two groups, which are distributed on the component units.

[0009] The component unit is a cup holder.

[0010] The work location is the installation port that communicates with the interior of the component unit.

[0011] It also includes a robotic arm structure for mounting the component unit, the robotic arm structure including a lateral movement unit and a longitudinal movement unit, wherein the longitudinal movement unit is mounted on a slider of the lateral movement unit, and the component unit is mounted on the slider of the longitudinal movement unit;

[0012] The horizontal moving unit and the vertical moving unit are respectively equipped with corresponding infrared sensors, and a set of baffles are installed on the vertical moving unit, with the baffles located between the light source unit and the infrared sensors.

[0013] Both the lateral and longitudinal movement units are driven by linear motors.

[0014] The beneficial effects of this utility model are: the structure is reasonably designed, and by setting the infrared sensor and the light source unit in the same direction, it avoids the light source shining on the sensing direction of the infrared sensor and generating incorrect signals, thereby reducing the false triggering of the vending machine and improving the customer's user experience.

[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0022] according to Figures 1 to 4 As shown: This embodiment provides an infrared sensor false triggering structure suitable for vending machines, including a component unit 100 on which a first infrared sensor 102 is installed, a light source unit 400 disposed near the component unit 100, and a robotic arm structure for mounting the component unit 100, wherein:

[0023] The component unit 100 is a cup holder with an internal cavity for placing paper cups and for selling ice cream. The lower part of the component unit 100 is mounted on a robotic arm structure, which allows the component unit 100 to move. Two sets of mounting ports 101 communicating with the internal cavity of the cup holder are provided on the side wall of the cup holder. The mounting ports 101 include two sets and are symmetrically distributed. The mounting ports 101 are also located close to the light source unit 400.

[0024] The light source unit 400 is a transparent window located on the door of the vending machine, allowing customers to see the product processing through the window. At the same time, external light sources can shine into the vending machine through the window.

[0025] The first infrared sensor 102 is provided and installed inside one of the mounting ports 101 of the component unit 100. The sensing operation direction of the first infrared sensor 102 is set towards the cavity of the component unit 100 to sense whether a cup is placed in the cup holder. The back side of the first infrared sensor 102 is the location of the light source unit 400, so that the sensing operation direction of the first infrared sensor 102 and the light source illumination direction of the light source unit 400 form an angle. The angle is an acute angle, and the light source unit 400 cannot directly illuminate the sensing operation position of the first infrared sensor 102. In this way, the first infrared sensor 102 will not be falsely triggered during the movement of the component unit 100 and the robotic arm structure.

[0026] The mounting port 101 includes two sets, which are distributed on the outer sidewall of the component unit 100. In this way, the first infrared sensor 102 can be installed in the mounting port 101 according to the position of the light source unit 400 of the cabinet door, making it more flexible to use.

[0027] The robotic arm structure includes a lateral movement unit 301 and a longitudinal movement unit 302, both of which are driven by linear motors. The longitudinal movement unit 302 is mounted on the slider of the lateral movement unit 301, and the component unit 100 is mounted on the slider of the longitudinal movement unit 302. The robotic arm structure can satisfy the lateral and vertical movement of the component unit 100. To ensure that the component unit 100 can be accurately reset, two sets of second infrared sensors 201 are installed at the initial position of the component unit 100. The second infrared sensors 201 are located on the lateral movement unit 301 and the longitudinal movement unit 302, respectively. A baffle 200 is installed on the longitudinal movement unit 302. The baffle 200 is located between the light source unit 400 and the two sets of second infrared sensors 201. That is, when the two sets of second infrared sensors 201 trigger each other, the baffle 200 can block the influence of the light source unit 400 on the movement of the two sets of second infrared sensors 201, preventing the two sets of second infrared sensors 201 from being falsely triggered.

[0028] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
