DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0034] Reference below Figures 1 to 6 , describing a laser aging stereo testing system 100 according to an embodiment of the present invention.

[0035] Combination Figures 1 to 6 As shown, a laser aging stereo testing system 100 according to an embodiment of the present invention includes a shelf 10, an aging target 40, a first pipeline assembly 20, a second pipeline assembly 30 and a loading and unloading robot (not shown in the figure).

[0036] The shelf 10 has multiple layers of cargo spaces for accommodating the lasers 200, and the shelf 10 is provided with a vertical hollow area 101. The aging target 40 is provided in the cargo space. The first pipeline assembly 20 is provided in the hollow area 101, and is used to provide coolant for the aging target 40. The second pipeline assembly 30 is provided on the front side of the shelf 10, adjacent to the first pipeline assembly 20, and is used to provide coolant for the laser 200. The loading and unloading robot is configured to move in the rear area of ​​the shelf 10, and is used to place the laser 200 to be tested for aging on the cargo space, and to move and transport the laser 200 that has completed the aging test to a designated location.

[0037] The shelf 10 can provide a placement location for the laser 200 and the aging target 40. The shelf 10 has a multi-layer structure. The number of shelves 10 is set according to actual needs. The shelves 10 can be arranged in a row or in multiple rows. The specific type of shelf 10 can be set according to actual needs, and there is no limitation on this. For example, the shelf 10 adopts a layered shelf and a split structure, and is two independent systems from the factory building, which has high flexibility. The number of layers of the shelf 10 is set according to actual needs. The hollow area 101 runs through the entire shelf 10, and the opening size of the hollow area 101 is adapted to the outer size of the first pipeline assembly 20.

[0038] The specific type of the laser 200 is set according to actual needs, and there is no specific restriction on this. For example, the laser 200 is a fiber laser, which has a chassis and an output armored cable. During the aging test, the chassis needs to be placed in the cargo space, and the output armored cable is connected to the aging target 40. The aging target 40 is also called an aging chamber, which recovers the laser during the aging process of the laser, and evaluates the long-term stability and reliability of the laser by observing the performance changes of the laser. The specific type of the aging target 40 is set according to actual needs, and there is no specific restriction on this. For example, the shape of the aging target 40 is a rectangular parallelepiped, and there should be enough space between the aging target 40 and the laser 200 to facilitate the handling operation of the loading and unloading robot.

[0039] The first pipeline assembly 20 and the second pipeline assembly 30 each include a plurality of main pipelines and branch pipelines, each branch pipeline is provided with a valve 91 to realize independent control of the branch pipeline. The branch pipeline has a liquid inlet main pipeline and a liquid outlet main pipeline, so that the coolant can take away the heat generated by the operation of the laser 200 and the aging target 40. The direction of the first pipeline assembly 20 and the second pipeline assembly 30 is set according to actual needs and is not limited to this. For example, the first pipeline assembly 20 and the second pipeline assembly 30 are arranged vertically to save space.

[0040] Loading and unloading robots can be rail-guided vehicles, shuttle vehicles, stackers, etc. Figure 1 and Figure 6 As shown, the loading and unloading robot is in the rear area of ​​the shelf 10, that is, Figure 6 The tester moves from the second area 400 in the rack 10 to the X direction, places the laser 200 to be tested on the shelf, and moves the laser 200 that has completed the aging test to the designated location. Figure 6 The first area 300 is operated and is responsible for plugging and unplugging electrical cables, output armored cables, cooling pipes, and valve opening and closing.

[0041] According to the laser aging three-dimensional testing system of the embodiment of the present invention, the number of lasers accommodated per unit area can be increased by arranging multi-layer cargo spaces on the shelves; the embodiment of the present invention arranges the first pipeline assembly in the hollow area and places the second pipeline assembly adjacent to the first pipeline assembly, thereby optimizing the overall pipeline layout design, reducing unnecessary bending and extension of the pipeline, achieving efficient space utilization in a limited space, reducing the demand for additional supporting structures, and reducing manufacturing costs; the embodiment of the present invention arranges the loading and unloading robots in the rear area of ​​the shelf for movement, thereby realizing automatic loading and unloading of lasers, eliminating manual handling, greatly improving testing efficiency, and allowing operators to work in the front area of ​​the shelf to achieve human-machine separation and ensure personnel safety.

[0042] In some embodiments, the laser aging stereo test system 100 also includes a frame 70 and a distribution box 50. The frame 70 is arranged on the front side of the shelf 10, and the distribution box 50 is installed on the front side of the frame 70. The frame 70 provides a stable support structure for the distribution box 50, and also protects the second pipeline assembly 30. The second pipeline assembly 30 is arranged in the frame 70, which can make full use of the space, and the frame 70 is also easy to assemble and disassemble. The distribution box 50 provides power for the laser 200. A leakage protection switch is provided in the distribution box to ensure the personal safety of the operator.

[0043] The left and right ends of the frame 70 are flush with the ends of the hollow area 101 in the X direction, and the left and right ends of the distribution box 50 are flush with the ends of the frame 70 in the X direction, which can fully utilize the space. There are multiple distribution boxes 50, which are arranged in multiple layers in the vertical direction.

[0044] In some embodiments, in combination Figure 1 and Figure 5 As shown, the hollow area 101 is set at the center of the shelf 10, the aging target 40 is adjacent to the second pipeline assembly 30, and the aging target 40 is symmetrically arranged along the two sides of the hollow area 101. In other words, each layer of the cargo space can accommodate 2 aging targets and 2 lasers, thereby improving space utilization.

[0045] The laser aging stereo test system further includes a flow meter 90, which is connected to the second pipeline assembly 30 and is used to monitor the coolant flow of the laser 200 during the aging process. The specific type of the flow meter 90 is set according to actual needs. For example, the flow meter 90 can be a volumetric type or a pressure differential type.

[0046] like Figure 3As shown, in some embodiments, the laser aging stereo test system 100 also includes a plurality of liquid receiving trays 60 and a balance pipe 61. The liquid receiving tray 60 is arranged at the bottom of the shelf 10, and each liquid receiving tray 60 is connected by a balance pipe 61. The liquid receiving tray 60 is used to receive the coolant leakage during the plugging and unplugging of the laser coolant pipeline. The coolant can maintain the same liquid level in each liquid receiving tray 60 to avoid overflow. The balance pipe 61 can be made of either a flexible material (such as rubber) or a rigid material (such as metal). At the same time, a pipe is provided at the bottom of at least one liquid receiving tray 60, which is connected to the drainage floor drain of the factory building, so that the leaked coolant can be discharged outside the factory building. In order to ensure a good coolant collection effect, the front side of the liquid receiving tray 60 protrudes toward the front side of the shelf 10 and is flush with the front side of the frame.

[0047] like Figure 1 As shown, the shelf 10 includes a plurality of columns 11, a leveling assembly 12 and a shelf 13. The shelf 13 is detachably connected to the column 11. The space between the shelves 13 of two adjacent layers forms a cargo space. The leveling assembly 12 is arranged at the bottom of the column 11. The leveling assembly 12 is used to level the shelf 10. The leveling assembly 12 includes an upper plate 121, a bottom plate 122 and an adjusting bolt 123. The adjusting bolt 123 is hinged to the bottom plate 122. The adjusting bolt 123 is threadedly connected to the upper plate 121. The upper plate 121 is connected to the bottom surface of the column 11. The spacing between the shelves 13 of two adjacent layers is reserved according to the thickness of the laser chassis, the thickness of the tooling fixture, and the safe spacing of the gripper of the loading and unloading robot. For example, the spacing between the shelves 13 of two adjacent layers is controlled at 300 mm to make full use of the vertical space. The horizontal space of the shelf 13 needs to reserve a safe distance to accommodate the laser.

[0048] The laser aging stereo test system also includes a first cooling pipeline 41 and a second cooling pipeline 42. The first cooling pipeline 41 and the second cooling pipeline 42 are connected between two aging targets 40 located in the same cargo space. The first cooling pipeline 41 and the second cooling pipeline 42 are cross-arranged, thereby reducing space waste caused by the bending of the cooling pipelines.

[0049] In addition, if Figure 5 As shown, the laser aging stereo test system also includes a control module 80 and a three-color warning light, which are arranged on the top of the shelf 10. The control module 80 is communicatively coupled with the laser 200, the flow meter 90 and the three-color warning light, respectively, and the control module 80 is used to monitor the operating status of the laser 200, the flow meter 90 and the three-color warning light. When the operating parameters of the laser 200 or the flow meter 90 are abnormal, the three-color indicator light can switch colors to show whether the current operating status is abnormal.
