The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] This invention improves the testing efficiency of POS machines by placing the POS machine on a rotating assembly using a four-axis pick-and-place assembly. The rotating assembly then rotates the POS machine to the corresponding automated testing assembly. After testing, the four-axis pick-and-place assembly picks up and places the POS machine to the next process.

[0035] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] Figures 1 to 5 A low-power leakage current testing device for a smart POS machine according to an embodiment of the present invention includes:

[0038] The four-axis pick-and-place assembly 2 is fixed to the platform 1 and picks up and places the POS machine to the corresponding workstation. Specifically, the four-axis pick-and-place assembly 2 includes a gantry structure XYZ motion platform 1. The POS machine is picked up and placed by a servo motor set on the Z-axis. The rotating end of the servo motor is equipped with at least two gripper cylinders. The gripper cylinders can pick up the POS machine to be tested from the external assembly line, or pick up the tested POS machine and place it on other conveyor lines.

[0039] The rotating assembly 3 includes a rotating drive 31, a rotating table 32, and a test tray 33 provided on the rotating table 32 for placing a POS machine structure. The rotating drive 31 drives the rotating table 32 to rotate, and the four-axis pick-and-place assembly 2 places the POS machine in the test tray 33 with the operation panel facing the platform 1.

[0040] Specifically, the rotation center of the rotary table 32 is provided with a hollow rotating shaft, the rotation drive 31 drives the rotating shaft to rotate, and the fixing component 4 passes through the hollow part of the rotating shaft and is fixedly connected to the platform 1.

[0041] The test bracket 33 is manufactured according to the POS machine casing. When the POS machine is placed in it, the operation panel with buttons faces downwards. The bottom of the test bracket 33 is hollowed out to expose the operation panel of the POS machine, which facilitates subsequent testing.

[0042] Fixing component 4 is provided corresponding to test bracket 33. The two together form a temporary locking mechanism to fix the POS machine in test bracket 33.

[0043] Specifically, the fixing component 4 includes a fixing bracket 41 and a fixing cylinder 42. The fixing cylinder 42 is positioned facing the POS machine. The telescopic end of the fixing cylinder 42 has a groove that matches the shape of the POS machine. The purpose of setting the fixing component 4 is to fix the POS machine to prevent displacement that could lead to failure of automated testing or damage to the interface due to misalignment of plugs and unplugs when the battery is removed or inserted, the button is pressed, or the side terminal is plugged in or unplugged.

[0044] The fixed bracket 41 can be adjusted in angle so that the fixed cylinder 42 can be adjusted to the most suitable position. The end of the fixed cylinder 42 has a groove that can cooperate with the POS machine. When the fixed cylinder 42 is activated, it can stably press the POS machine into the test bracket 33.

[0045] Appearance inspection component 5, located on platform 1, photographs the POS machine panel; used for appearance inspection of the POS machine.

[0046] Specifically, the appearance inspection component 5 includes an illumination element 51 and an imaging element 52. The illumination element 51 is fixed to the platform 1, with the light-emitting area facing the POS machine panel. The imaging element 52 captures images of the POS machine panel. The imaging element 52 transmits the captured images to an external system, and uses machine vision recognition and other methods to determine whether the appearance of the POS machine meets the requirements.

[0047] The IoT detection component 6 includes a battery removal and placement element 61, an IoT detection element 62, and a power supply detection element 63. The battery removal and placement element 61 removes the battery from the POS machine, exposing the IoT card slot. The IoT detection element 62 connects to the contacts of the IoT card slot. The power supply detection element 63 connects to the power supply terminal on the side of the POS machine to supply power.

[0048] The physical appearance of the IoT card is similar to that of a common SIM card. The IoT card is located inside the device and is covered by the battery. In the factory state, the POS machine does not have a card inserted. In order to test whether the card slot is working properly, the battery needs to be temporarily removed and an external power supply is used instead.

[0049] Specifically, the battery pick-and-place element 61 includes a vertical cylinder, a rotary cylinder, and a suction cup. The vertical cylinder drives the cantilever to move up and down. The cantilever is equipped with a rotary cylinder. The rotating end of the rotary cylinder is equipped with a crossbeam. The crossbeam is equipped with a suction cup corresponding to the position of the POS machine battery. The vertical movement of the vertical cylinder, in conjunction with the rotary cylinder, drives the crossbeam to swing, so that the suction cup contacts the POS machine battery.

[0050] After the suction cup holds the battery, the vertical cylinder moves upward to pull it out of the POS machine, and the rotary cylinder rotates, causing the battery to move away from the position that is blocking the IoT card slot.

[0051] The IoT detection element 62 includes several probes. The probes are connected to external devices and can provide detection signals. The probes are driven by a vertical cylinder mounted on the platform 1. When the battery swings to a position where it is not obstructed, the probes press down to contact the contacts and establish a data connection.

[0052] The power supply detection element 63 includes a movable frame consisting of two mutually perpendicular cylinders and a DC terminal located on the movable frame. The DC terminal is driven by the movable frame and inserted into the power supply port on the side of the POS machine.

[0053] Once the IoT detection probe is connected to the POS machine, the DC terminal is inserted to power the POS machine. The structure consisting of two vertical cylinders allows the DC terminal to avoid the rotating stage 32 when not in use, preventing motion interference.

[0054] After the IoT test is completed, the DC terminal is pulled out, the IoT detection element 62 moves upward away from the contact, the battery pick-and-place element 61 puts the battery back into the POS machine, and the entire IoT detection component 6 retracts to its initial state after the test is completed.

[0055] In addition to the part that communicates with the outside via IoT, some functions inside the POS machine also need to be initialized. It communicates with the host via USB protocol, so function detection component 7 is set up.

[0056] The function detection component 7 includes a communication detection element 71 and a button pressing element 72. The communication detection component is connected to the communication terminal on the side of the POS machine for communication. The button pressing element 72 is mounted on the platform 1 through a three-axis movable structure and has a pressing rod facing the POS machine operation panel. The pressing rod moves to different button positions on the POS machine panel to press the button.

[0057] Optionally, the button pressing element 72 includes a horizontal moving platform 1 and a pressing cylinder. The horizontal moving platform 1 realizes the movement of the horizontal and vertical coordinates on the plane of the platform 1, while the pressing cylinder is located on the horizontal moving platform 1, and the telescopic end realizes the movement in the direction perpendicular to the platform 1. Through this structural combination, the button of the POS machine is pressed to simulate the operation process of a person operating the POS machine. During this process, the communication detection element 71 reads and writes information of the POS machine.
