[0066] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0067] The embodiment of the utility model provides a code scanning function testing device, including a testing platform;

[0068] The test platform is provided with a three-axis moving mechanism and a left-right flipping mechanism;

[0069] The three-axis moving mechanism is provided with an up-and-down flipping mechanism, and the up-and-down flipping mechanism is used to fix the code display device;

[0070] The left-right flipping mechanism is opposite to the up-down flipping mechanism, and the left-right flipping mechanism is used to fix the code scanning device.

[0071] From the above description, it can be seen that the beneficial effects of the utility model are: a three-axis moving mechanism, a left-right flipping mechanism, and an up-down flipping mechanism are integrated on the test platform, and the up-down flipping mechanism with a display code device is set on the three-axis moving mechanism, and the left-right flipping mechanism with a code scanning device is fixed to the up-down flipping mechanism, so that the code scanning device can scan and process the code information displayed on the display code device. The position parameters and moving speed of the display code device can be adjusted by the three-axis moving mechanism, and the deflection angles of the code scanning device and the display code device can be adjusted by the left-right flipping mechanism and the up-down flipping mechanism, so that the relevant data adjustment of all code scanning tests can be realized on a test platform to meet all test requirements of the code scanning function and improve the test efficiency.

[0072] Further, the three-axis moving mechanism includes an X-axis moving component, a Y-axis moving component and a Z-axis moving component;

[0073] The Y-axis moving component is fixed on the test platform;

[0074] The X-axis moving component is slidably disposed on a side of the Y-axis moving component away from the test platform;

[0075] The Z-axis moving member is slidably disposed on a side of the X-axis moving member opposite to the left-right flipping mechanism;

[0076] The up-and-down flipping mechanism is slidably arranged on a side of the Z-axis moving component opposite to the left-and-right flipping mechanism.

[0077] From the above description, it can be seen that by setting the X-axis moving component, the Y-axis moving component and the Z-axis moving component, the relative position relationship between the code display device and the code scanning device can be adjusted, and an up and down flipping mechanism is set on the Z-axis moving component to meet the needs of the code scanning device to perform tests at different positions and angles with different moving speeds.

[0078] Further, the Y-axis moving member includes a first Y-axis component, a second Y-axis component and a connecting rod component;

[0079] The first Y-axis component and the second Y-axis component are arranged parallel to each other on the test platform;

[0080] The two ends of the connecting rod component are respectively connected to the first Y-axis component and the second Y-axis component;

[0081] Two ends of the X-axis moving member are slidably disposed on the first Y-axis component and the second Y-axis component, respectively, and the first Y-axis component and the second Y-axis component are both perpendicular to the X-axis moving member.

[0082] As can be seen from the above description, the Y-axis moving component is composed of a first Y-axis component and a second Y-axis component to ensure the stability of the X-axis moving component when moving, and to provide sufficient movement space for the display code device to move in the X-axis. At the same time, the first Y-axis component and the second Y-axis component are connected based on a connecting rod component to ensure that the two Y-axis components move synchronously.

[0083] Furthermore, the left-right flipping mechanism includes a first clamping member, an L-shaped supporting member and an angle scale dial;

[0084] The angle scale turntable is rotatably disposed on the test platform;

[0085] One end of the L-shaped support member is fixed to the angle scale turntable;

[0086] The first clamping member is fixed to the other end of the L-shaped supporting member, and the first clamping member is used to fix the code scanning device.

[0087] As can be seen from the above description, the angle scale dial is rotated and set on the test platform, and the L-shaped support member fixed with the first clamping member is fixed to the angle scale dial, so that the code scanning device fixed on the first clamping member can achieve left and right offset. At the same time, the angle test data of the code scanning device is recorded based on the angle scale dial to meet the test requirements of the code scanning device at different offset angles.

[0088] Furthermore, the up-and-down turning mechanism comprises a second clamping member, a U-shaped fixing member, a worm shaft, a worm wheel shaft and a linkage member;

[0089] The U-shaped fixed component is slidably disposed on the Z-axis moving component;

[0090] The worm gear shaft is rotatably arranged at the opening of the U-shaped fixing member, and angle scale members are arranged at both ends of the worm gear shaft;

[0091] The worm shaft is rotatably disposed on the U-shaped fixing member, and the worm shaft and the worm wheel shaft are meshed with each other, so that when the worm shaft rotates, the worm wheel shaft is driven to rotate;

[0092] An adjusting handle is fixed to one end of the worm shaft;

[0093] One end of the linkage member is vertically fixed to the worm gear shaft, and the second clamping member is fixed to the other end of the linkage member, and the second clamping member is used to fix the display code device.

[0094] From the above description, it can be seen that the worm shaft is driven to rotate by adjusting the handle, and then the worm shaft drives the worm wheel shaft to rotate synchronously, thereby driving the linkage component to rotate, so that the display code device is offset up and down. In addition, based on the self-locking function between the worm shaft and the worm wheel shaft, the display code device is prevented from shaking and offsetting during movement, ensuring the test accuracy. At the same time, the angle test data of the display code device is recorded based on the angle scale component to meet the test requirements of the display code device at different offset angles.

[0095] Furthermore, the test platform includes a cover plate and a box body;

[0096] One side of the cover plate is fixed to the top of the box body to form a cavity;

[0097] The three-axis moving mechanism and the left-right flipping mechanism are both arranged on the other side of the cover plate;

[0098] An electric control mechanism is arranged in the cavity, and the electric control mechanism is used to control the three-axis moving mechanism.

[0099] It can be seen from the above description that the cavity formed by the box body and the cover plate protects the electric control mechanism to achieve dust and water resistance.

[0100] Further, it also includes an extension movement mechanism;

[0101] An opening is provided on a side of the box body opposite to the up-and-down turning mechanism;

[0102] One end of the extending and moving mechanism passes through the opening and is slidably disposed in the cavity;

[0103] The left-right flipping mechanism is arranged at the other end of the extending moving mechanism;

[0104] The cover plate is provided with a U-shaped opening at an edge close to the opening, and the U-shaped opening is used to accommodate the left-right flipping mechanism when the extending movement mechanism is located in the cavity.

[0105] From the above description, it can be seen that by slidingly setting an extending movable mechanism in the cavity and setting the left and right flipping mechanism on the extending movable mechanism, the test platform can further test the extreme scanning distance of the code scanning device without increasing the volume, so as to meet the depth of field test requirements of the code scanning function.

[0106] Furthermore, the extending movement mechanism includes an extending plate, a guide rail and a guide rail slider;

[0107] The left-right flipping mechanism is arranged on a side of the extension plate close to the cover plate;

[0108] The guide rail is fixed to the bottom plate of the box body, and the guide rail is perpendicular to the up-and-down turning mechanism;

[0109] Side panels are provided on opposite sides of the extension plate;

[0110] The guide rail slider is fixed between the side plates and is slidably connected to the guide rail.

[0111] It can be seen from the above description that the guide rail and the guide rail slider are slidably connected so that the extension plate can move along a specified direction in the cavity, thereby adjusting the relative distance between the code display device and the code scanning device.

[0112] Furthermore, a limiting block is provided on a side of the side plate away from the guide rail slider;

[0113] The bottom plate of the box body is provided with two limit grooves which are parallel to the guide rail;

[0114] The two limit grooves are respectively located on both sides of the guide rail and correspond one to one with the side panels;

[0115] The side plate is located in the limiting groove.

[0116] As can be seen from the above description, by providing a limit block, the extension plate is prevented from being completely withdrawn from the cavity. At the same time, a limit groove is provided so that the extension plate can slide in the direction of the guide rail.

[0117] Furthermore, a foldable handle is provided on the side panel of the box.

[0118] It can be seen from the above description that the test platform is convenient to carry by providing a foldable handle.

[0119] The embodiment of the utility model provides a code scanning function test device, which can be applied to the code scanning function test of the intelligent POS machine, and can meet all the test requirements of the product for the code scanning function to improve the test efficiency.

The Y-axis motor 224 drives the connecting rod component 223 to rotate, and then the connecting rod component 223 synchronously drives the first Y-axis component 221 and the second Y-axis component 222, thereby moving the X-axis moving component 21 located on the Y-axis moving component 22.

The routine test is specifically a barcode scanning test with no limit on distance, no limit on moving speed, and no limit on scanning angle. After the routine test is completed, the barcode scanning function needs to be tested for angle, moving speed, depth of field distance, fixed focus, and zoom.

[0139] The angle test is specifically as follows: the operator inputs instructions on the touch screen to control the movement parameters of the three-axis moving mechanism, so that the up and down flip mechanism moves to the specified position; at the same time, the operator manually adjusts the adjustment handle to make the display code device flip up and down to the specified angle, and controls the display code device to move to the specified position through the Z-axis moving component; at the same time, the operator manually adjusts the angle scale dial to make the code scanning device flip left and right to the specified angle, and controls the code scanning device to move to the specified position through the X-axis moving component.

[0140] The mobile speed test is as follows: the operator fixes the barcode scanning device at the specified position, and controls the Z-axis moving component to stop at the specified height through the touch screen. The X-axis moving component reciprocates on the Y-axis moving component at a specified speed. At the same time, the barcode scanning device starts the barcode scanning test mode. When the display barcode device moves at the test speed, if the barcode scanning device can scan the code normally, it means that the test has passed.

[0141] The depth of field test is as follows: the operator controls the Y-axis moving component to return to its original position through the touch screen, and manually pulls the extended moving mechanism out to different distances until the code scanning device cannot scan the code, thus completing the depth of field test.

[0142] In summary, the utility model provides a code scanning function test device, which is provided with an X-axis moving component, a Y-axis moving component and a Z-axis moving component on the test platform, and can adjust the relative position relationship between the display code device and the code scanning device, and set an up and down flip mechanism on the Z-axis moving component to meet the needs of testing the code scanning device at different positions and different angles with different moving speeds. At the same time, the angle scale dial is rotated and set on the test platform, so that the code scanning device fixed on the angle scale dial can achieve left and right offsets to meet the test requirements of the code scanning device at different offset angles. In addition, a worm gear shaft and a worm shaft that mesh with each other are set, and through the cooperation between the worm gear shaft and the worm shaft, the display code device is offset up and down to meet the test requirements of the display code device at different offset angles. In addition, an extension moving mechanism is slidably set in the cavity, and the left and right flip mechanism is set on the extension moving mechanism, so that the test platform can further test the extreme scanning distance of the code scanning device without increasing the volume, so as to meet the depth of field test requirements of the code scanning function. Therefore, the utility model can meet all the test requirements of the product for the code scanning function and improve the test efficiency of the code scanning function.
