Description

Technical Field

[0001] The utility model belongs to the technical field of additive manufacturing, and in particular relates to a multifunctional portable optical testing platform. Background Art

[0002] Additive manufacturing technology is an advanced manufacturing technology with distinctive features such as digital manufacturing, high flexibility and adaptability, direct CAD model drive, fast speed, and rich and diverse material types. Since it is not limited by the complexity of the part shape and does not require any tooling, it has a very wide range of applications. As one of the additive manufacturing technologies, the selective laser sintering process has the following basic process: the powder feeding device delivers a certain amount of powder to the work surface, the powder spreading roller spreads a layer of powder material on the upper surface of the formed part of the forming cylinder, the heating device heats the powder to the set temperature, and the galvanometer system controls the laser to scan the solid part powder layer according to the cross-sectional profile of the layer, so that the powder melts and bonds with the formed part below; when a layer of cross section is sintered, the workbench drops a layer of thickness, and the powder spreading roller spreads a layer of uniform and dense powder on it, and scans and sinters a new layer of cross section, and after several layers of scanning and superposition, the entire prototype manufacturing is completed.

[0023] In order to enable those skilled in the art to better understand and implement the technical solution of the utility model, further detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1-Figure 3 The multifunctional portable optical test platform shown includes:

[0025] A main panel 1, on which a through hole 2, at least one first mounting hole 3, at least one second mounting hole 5, and at least one third mounting hole 4 are provided;

[0026] Two side panels 6 are flipably mounted on both sides of the main panel 1 via hinges 11, and a first mounting groove 9 for vertically fixing the aperture 10 is provided on the upper surface of the side panel 6, and a hole is extended inward along a groove wall of the first mounting groove 9 to form a second mounting groove for horizontally fixing the aperture 10.

[0027] Preferably, a retractable support rod 7 is connected to the side of the side panel 6 away from the main panel 1, and a support plate 8 is connected to the end of the support rod 7 away from the side panel 6. In this way, the height of the multifunctional portable optical test platform can be freely adjusted when used as a support platform, and the stability of the test platform is further ensured.

[0028] In a specific implementation, the through hole 2 is located at the center of the main panel 1 for installation scenes. There are four first mounting holes 3 for fixing the galvanometer base plate and located at the four corners of the main panel 1. There are two second mounting holes 5 and two third mounting holes 4, which are respectively arranged on both sides of the through hole 2. The second mounting hole 5 is used to install a fixing frame to fix the output end of the laser; the third mounting hole 4 is used to fix the power meter probe.

[0029] In another specific implementation, the second mounting groove is arranged away from the through hole 2, and the second mounting grooves of the two side panels 6 are arranged at the same position of the side panels 6. Of course, in a specific implementation, the second mounting groove can also be arranged on any side wall of the first mounting groove 9. The support rod 7 can be extended by at most 3 sections, and the maximum adjustment distance is 50 cm.

[0030] The multifunctional portable optical test platform of this embodiment is adjusted into three different test structures by folding and unfolding to test different parameters of the optical system according to actual needs. The working process of the three different test structures is described in detail below:

[0031] like Figure 1 As shown, when the two side panels 6 are both turned down 180 degrees relative to the main panel 1 and are parallel to the lower side of the main panel 1, the multifunctional portable optical test platform is used to test the power after the laser output. Specifically, the fixing frame is installed in the second mounting hole 5 for fixing the output end of the laser, and the power meter probe bracket is installed in the third mounting hole 4 at a symmetrical position of the second mounting hole 5 for fixing the power meter probe, so that the power meter probe can collect the power after the laser output (i.e., for measuring the bare fiber power), and the measurement distance is met to ensure that the light spot is large enough, and the use is safer, and the fiber deviation will not cause safety problems.

[0032] like Figure 2As shown, when the two side panels 6 are unfolded parallel to the main panel 1 and are located at the same horizontal plane as the main panel 1, the multifunctional portable optical test platform is used to test the difference deviation angle between the optical axis of the actual light beam output by the laser and the ideal optical axis after passing through the collimator and the steering module. Specifically, the collimator is installed on the support plate 8 through the mounting plate, the diaphragm 10 is taken out, and it is vertically fixed in the first mounting groove 9. Specifically, the diaphragm 10 can be fixed by screws. The laser output by the laser is sequentially captured on the two diaphragms 10 of the two side panels 6 after being aligned by the external coaxial device. Before this, the two diaphragms 10 need to be fine-tuned so that the two diaphragms 10 are in a coaxial state. The bull's eye at the center of the diaphragm 10 can be taken out. After measuring the position of the light spot at the first diaphragm 10, the bull's eye of the diaphragm 10 can be taken out, and then the light spot is hit to the position of the second diaphragm 10. According to the position distance of the light spot at the bull's eye of the two diaphragms 10, and the optical axis offset is calculated according to the principle of similar triangles, the deflection angle of the light beam after passing through the collimator or the steering module is determined.

[0033] When the diaphragm 10 is not in use, it can be placed in the second installation groove, which saves space and is convenient for use at any time. Specifically, it can be fixed in the second installation groove by using screws.

[0034] like Figure 3 As shown, when the two side panels 6 are both turned down 90 degrees relative to the main panel 1 to support the main panel 1, the multifunctional portable optical test platform is used for spot testing. At this time, the two side panels 6 can be used as a simple optical system work platform when used as a bracket. The output end of the laser is fixedly installed in the second mounting hole 5 of the main panel 1 through a fixing frame, the collimator is installed on the galvanometer, the galvanometer is fixedly installed in the first mounting hole 3 of the main panel 1 through the galvanometer bottom plate, and the field lens is fixedly installed in the through hole 2 of the main panel 1. A power meter is placed at the central bottom of the optical test platform. The laser emitted by the laser can pass through and test the spot, M of the power meter under the action of the collimator and the field lens. 2 And optical parameters such as optical system output power.
