[0048] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0049] In order to solve the technical problem in the prior art that it is impossible to test the stability and impact resistance of optical components under extreme motion conditions, which is not conducive to ensuring the effect of laser operations and the performance of photovoltaic products; the applicant has developed a motion experimental platform for laser flight optical paths, which can control the high-speed movement of optical components related to the flight pipeline of the laser system, and test the laser operation performance of the optical components under high-speed movement, thereby helping to ensure the effect of laser operations and the performance of photovoltaic products.

[0050] Specifically, see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an embodiment of a motion experimental platform for the laser flight optical path of the present application. Figure 2 It is a top view structural diagram of an embodiment of the motion experiment platform of the present application in working state. Figure 3 yes Figure 2 Schematic diagram of the cross-sectional structure of the AA surface in the middle.

[0051] like Figures 1 to 3As shown, the motion experiment platform includes a working platform 100, and the working platform 100 includes a working surface 101 located on the top surface.

[0052] The working surface 101 is provided with a movable guide rail 200 extending in the X-axis direction, and a slidable slide plate base 300 ( Figure 1 (not shown in the figure), a transfer mounting seat 400 is arranged on the slide base 300, and a test surface 401 for mounting the optical component 1200 to be tested is arranged on the transfer mounting seat 400.

[0053] A driving mechanism for driving the slide base 300 to slide is also arranged on the working surface 101 .

[0054] Specifically, in the present embodiment, a pair of movable guide rails 200 arranged in parallel and spaced apart are arranged on the working surface 101 , and the driving mechanism includes a linear motor 500 arranged between the pair of movable guide rails 200 .

[0055] The stator 501 of the linear motor 500 is fixed on the working surface 101 , and the mover 502 is connected to the slide base 300 .

[0056] Based on the above structure, the linear motor 500 can drive the slide base 300 to reciprocate at high speed on the moving guide rail 200, thereby driving the optical component to be tested 1200 located on the adapter mount 400 to reciprocate at high speed. For different optical components 1200 to be tested, the optical components 1200 to be tested can be replaced by replacing the adapted adapter mount 400, thereby meeting the testing requirements of different optical components 1200.

[0057] It is understandable that in other embodiments, the driving mechanism may also be other linear driving devices commonly used in the art, such as a motor screw nut structure, a telescopic cylinder, a hydraulic cylinder, etc., which can also achieve the effect of this embodiment.

[0058] In order to realize the position tracking of the optical component 1200, in the present embodiment, a grating ruler 600 is also arranged on the working surface 101. The grating ruler 600 is arranged between a pair of movable guide rails 200 and is used to detect the position of the slide base 300, so as to determine the real-time position of the optical component 1200 to be tested.

[0059] In order to ensure the movement accuracy of the optical component 1200 to be tested and offset the magnetic attraction between the mover 502 and the stator 501 of the linear motor 500, in this embodiment, the skateboard base 300 and the adapter mount 400 can both be high-strength aluminum plates, and the working platform 100 can be a natural marble platform.

[0060] To implement testing of the optical assembly 1200, see Figure 1 and Figure 2 A workpiece supporting mechanism 700 and a laser generating mechanism 800 are also arranged on the working surface 101 .

[0061] The workpiece support mechanism 700 includes a workpiece support position 702 located above the adapter mount 400, and the workpiece support position 702 is used to place the test device 1300; illustratively, when testing the optical component 1200 of the laser scribing system, the test device 1300 can be glass.

[0062] The laser generating mechanism 800 is used to transmit laser light to the optical component 1200 to be tested located on the test surface 401 .

[0063] It can be understood that during the experiment, the laser generating mechanism 800 can continuously transmit laser to the optical component 1200 to be tested along the X-axis direction, and synchronously control the optical component 1200 to be tested to reciprocate along the movable guide rail 200. During the movement, the optical component 1200 to be tested can continuously apply laser to the test device 1300 located above it, and the stability and optical process performance of the optical component 1200 during high-speed movement can be tested by judging the laser operation effect of the test device 1300.

[0064] Specifically, in this embodiment, the workpiece support mechanism 700 includes an inverted L-shaped bracket 701 symmetrically arranged on both sides of the movable guide rail 200, the top surfaces of a pair of inverted L-shaped brackets 701 cooperate to form a workpiece support position 702, and a gap is formed between the pair of inverted L-shaped brackets 701 for the adapter mounting seat 400 to pass through.

[0065] In other embodiments, the workpiece supporting mechanism 700 may also adopt other supporting structures, such as a cantilever supporting structure arranged on one side of the movable guide rail 200, etc., which will not be described in detail here.

[0066] See also Figure 4 , Figure 4 It is a structural schematic diagram of an implementation method of the motion experiment platform of the present application after the laser generating mechanism housing is removed.

[0067] like Figure 4 As shown, in this embodiment, the laser generating mechanism 800 includes a laser source 801 , a beam expander 802 , a first reflector 803 and a second reflector 804 .

[0068] Among them, the laser source 801 is arranged on the Y-axis side of the movable guide rail 200, the beam expander 802 is arranged on the X-axis side of the laser source 801, the first reflector 803 is arranged on the X-axis side of the beam expander 802, and the second reflector 804 is arranged on the X-axis side of the adapter mount 400.

[0069] The first reflector 803 and the second reflector 804 cooperate to adjust the angle of the laser by 180° and then direct the laser toward the optical component 1200 to be tested located on the test surface 401 .

[0070] The laser generating mechanism 800 based on the above structure can effectively utilize the table space of the working surface 101 and reduce the floor space of the experimental platform by arranging the laser source 801 on one side of the movable guide rail 200 and reflecting and expanding the laser beam. Of course, in other embodiments, the laser source 801 can also be directly arranged at the end of the movable guide rail 200 to emit laser to the optical component 1200 to be tested, etc., and the experimental effect can also be achieved.

[0071] It can be understood that the motion experiment platform of this embodiment can be applied to the test of the optical component 1200 that can directly receive the incident laser. In some application scenarios, the optical component 1200 to be tested may be an optical component 1200 that receives the laser through an optical fiber. In order to make the motion experiment platform of this embodiment applicable to the test of the optical component 1200 that needs to be connected to the optical fiber, please refer to Figure 1 In this embodiment, the motion experiment platform also includes a drag chain 900 arranged next to the adapter mounting seat 400 for receiving the optical fiber.

[0072] Based on this solution, when testing an optical component 1200 that can directly receive incident laser light, the laser can be emitted into the optical component 1200 through the laser source 801; when testing an optical component 1200 that can only receive laser light through an optical fiber, the optical fiber can be inserted into the drag chain 900 and connected to the optical component 1200, thereby improving the scope of application of the motion experiment platform of this embodiment.

[0073] In the above-mentioned embodiments, the upper parts of the movable guide rail 200 and the linear motor 500 are hollowed out, and there may be a risk of foreign matter falling onto the movable guide rail 200 and the linear motor 500 during operation, posing a safety hazard. In particular, metal foreign matter may be absorbed by the stator 501 of the linear motor 500, causing damage to the motor.

[0074] To avoid the above security risks, please refer to Figure 5 , Figure 5 It is a schematic diagram of the top view of another embodiment of the motion experiment platform of the present application.

[0075] like Figure 5 As shown, the motion experiment platform further includes end plates 1000 arranged at both ends of the moving guide rail 200 in the X-axis direction, and a U-shaped accordion cover plate 1100 is arranged between each end plate 1000 and the corresponding end of the adapter mounting seat 400 .

[0076] The U-shaped accordion cover plate 1100, the end plate 1000 and the adapter mounting seat 400 can cooperate to form a sealed space, and the linear motor 500 and the movable guide rail 200 can be accommodated in the sealed space to avoid safety hazards.

[0077] The motion experimental platform based on the above-mentioned embodiments can realize the stability and optical process performance testing of the optical components 1200 related to the flying optical path under high-speed motion, which helps to ensure the operating effect of subsequent laser operations and the performance of optical devices.
