Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing fixtures, and in particular to a testing fixture for line laser components. Background Technology
[0002] Line laser components are widely used in robotic vacuum cleaners for distance measurement, making their power and accuracy crucial. Therefore, testing of these components is necessary. However, existing line laser components typically test the laser quality at a single location. Laser quality includes the laser width, power, deflection angle, and divergence angle, which can easily introduce errors. To reduce these errors, multiple tests are required, leading to low efficiency, increased costs, and higher labor intensity. Furthermore, the testing process can potentially cause injury to personnel. Utility Model Content
[0003] To address the aforementioned shortcomings, this invention provides a line laser component testing fixture that can more accurately test the quality of the laser when facing objects at different distances, thereby improving testing efficiency, reducing testing costs, lowering the labor intensity of the testing process, and ensuring that the testing process does not cause harm to the human body.
[0004] To achieve the purpose of this utility model, the present utility model proposes the following technical solution: a line laser component testing fixture, including a test table, a control console, a guide rail set on the top of the test table, a platform fixed to one end of the guide rail, an optical power meter set on the platform and movable up and down, a line laser component set on the platform and located below the optical power meter, a display whiteboard that can reciprocate along the guide rail and is positioned towards the line laser component, and a camera located between the platform and the display whiteboard and reflecting the distance to the display whiteboard.
[0005] Based on the above technical solution, the following supplementary technical solutions are further included:
[0006] It also includes tooling fixtures set on the platform for fixing the line laser assembly, wherein the tooling fixtures are located on both sides of the laser assembly.
[0007] It also includes a cylinder for fixing an optical power meter at one end, and a support member set on the platform and fixing the other end of the cylinder, wherein the extension direction of the support member is perpendicular to the plane where the guide rail is located, and the optical power meter moves up and down with the cylinder to align with the line laser assembly to test the power value of the line laser assembly.
[0008] The console is positioned close to the whiteboard and away from the platform, and the extension direction of the console is perpendicular to the plane where the guide rail is located.
[0009] The console includes a display screen for showing test data and an operation panel for inputting data.
[0010] The line laser component is located above the camera and is positioned at a certain distance so that the camera does not block the line laser within its corresponding travel range, while simultaneously ensuring that the camera can capture the image displayed on the whiteboard by the line laser.
[0011] It also includes a sliding part for supporting the display whiteboard and moving along the guide rail.
[0012] It also includes a horizontal connecting part that is connected to the sliding part at one end and extends along the guide rail direction, a vertical connecting part that is connected to the other end of the horizontal connecting part at the bottom end and extends along the vertical guide rail direction, and a camera support part located at the top of the vertical connecting part and supporting the camera.
[0013] It also includes a support arm that is perpendicularly connected to the sliding part and located on the other side of the display whiteboard, the support arm being positioned towards the console and away from the platform.
[0014] The distance the display whiteboard moves is obtained through signal feedback from the stepper motor, and the projection surface of the optical power meter coincides with the projection surface of the display whiteboard.
[0015] The beneficial effects of this invention are: when facing objects at different distances, the quality of the laser can be tested more accurately, improving detection efficiency, reducing detection costs, reducing the labor intensity of the detection process, and the detection process will not cause harm to the human body.

[0025] Example: Figure 1-6As shown, this utility model discloses an embodiment of a testing fixture for a line laser component, which includes a test platform 10 with a test top 100, a control console 12, a guide rail 120 disposed on the test top 100, a platform 200 fixed to the guide rail 120, an optical power meter 260 disposed on the platform 200, a line laser component 300 disposed on the platform 200 and located below the optical power meter 260, a display whiteboard 420 reciprocating along the guide rail 120 and facing the line laser component 300, a fixture 320 disposed on the platform 200 and used to fix the line laser component 300, and a cylinder 240 for fixing the optical power meter 260 at one end. The system includes a support member 220 mounted on the platform 200 and fixing the other end of the cylinder 240; a camera 480 located between the platform 200 and the display whiteboard 420; a sliding part 400 supporting the display whiteboard 420 and moving along the guide rail 120; a horizontal connecting part 440 connected at one end to the sliding part 400 and extending along the guide rail 120; a vertical connecting part 460 whose bottom end is connected to the other end of the horizontal connecting part 440 and extending along the vertical guide rail 120; a camera support part 470 located at the top of the vertical connecting part 460 and supporting the camera 480; and a stop arm 490 vertically connected to the sliding part 400 and located on the other side of the display whiteboard 420. The stop arm 490 faces the control console 12 and is away from the platform 200. The display whiteboard 420 reciprocates via a stepper motor.
[0026] Both the test platform 10 and the control console 12 are mounted on a horizontal plane. The control console 12 is positioned closer to the display whiteboard 420 and further away from the platform 200, and its extension direction is perpendicular to the plane of the guide rail 120. The control console 12 includes a display screen 14 for displaying test data and an operation panel 16 for inputting data. The guide rail 120 has graduations, wherein the projection surface of the optical power meter 260 coincides with the projection surface of the display whiteboard 420 in the extension direction of the guide rail 120. The guide rail 120 is 1000 mm long and can be automatically adjusted after the required distance is set.
[0027] The stage 200 spans the guide rail 120 and is higher than the plane of the guide rail 120. The support member 220 extends perpendicularly to the plane of the guide rail 120 and is mounted on the stage 200. The cylinder 240 is fixed by the support member 220, and its output end is connected to the optical power meter 260, thereby enabling the optical power meter 260 to reciprocate on the plane perpendicular to the guide rail 120. The sliding part 400 is driven by a stepper motor and a transmission mechanism, and this stepper motor can be controlled by the control console 12, thereby realizing automatic testing.
[0028] The line laser assembly 300 is roughly cylindrical, with one end facing the white display panel 420, and its two sides and the other end clamped by the fixture 320. The line laser assembly 300 is located above the camera 480. The power supply specification for the line laser assembly 300 during testing is 30V / 5A.
[0029] Therefore, the testing process for this utility model is as follows:
[0030] 1. The line laser assembly 300 is placed on the tooling fixture 320;
[0031] 2. Press the start button to begin the test;
[0032] 3. The stage 200 of the fixed line laser assembly 300 is close to the test surface (i.e., the white display board 420) via the guide rail 120. The guide rail 120 is graduated and can allow the stage 200 to move arbitrarily within a range of 1m. Currently, the test requires the measurement of the line width and divergence angle of the line laser spot at positions of 700mm, 300mm and 50mm.
[0033] 4. The laser beam hits the display whiteboard 420 (power meter sensing area) to calculate the laser power of the line;
[0034] 5. Test items read from the host computer in console 12: line laser power, test voltage, test current, line width, divergence angle, and deflection angle;
[0035] 6. The test data is uploaded to the host computer and automatically determined as OK or NG.
[0036] The advantages of this invention are: it can more accurately test the quality of the laser when facing objects at different distances, improve detection efficiency, reduce detection costs, reduce the labor intensity of the detection process, and will not cause harm to the human body during the detection process.
[0037] The above are merely preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
