[0042] The following is for reference. Figures 1 to 8 This invention describes a light source lifting and adjusting module according to an embodiment of the present invention.

[0043] like Figures 1 to 4 As shown, a light source lifting and adjusting module according to an embodiment of the present utility model includes a base frame 100, a lifting module 200, a transmission structure 300, a light source mounting structure 400, a guide structure 500, and a driving component 600.

[0044] The base frame 100 includes a first support 110 and a second support 120 arranged opposite to each other. The lifting module 200 includes a first movable component 210, a second movable component 220, and a third movable component 230. The fixed end of the first movable component 210 is connected to the first support 110, and the fixed ends of the second and third movable components 220 and 230 are connected to the second support 120. The first movable component 210, the second movable component 220, and the third movable component 230 are connected through a transmission structure 300. The light source mounting structure 400 is suitable for mounting a light source. The light source mounting structure 400 is disposed between the first support 110 and the second support 120. The light source mounting structure 400 is connected to the base frame 100 through several guide structures 500. The light source mounting structure 400 can be displaced relative to the base frame 100 along the directions of the several guide structures 500. The light source mounting structure 400 is connected to the movable ends of the first movable component 210, the second movable component 220, and the third movable component 230. The output end of the drive component 600 is connected to the lifting module 200.

[0045] During product testing, the product to be tested is placed below the light source mounting structure 400. The light source mounting structure 400 is suitable for placing the light source, and the emitting surface of the light source faces the product to be tested. The first movable component 110, the second movable component 120, and the third movable component 130 form a stable triangular support structure, which allows the light source mounting structure 400 to be stably installed on the first bracket 110 and the second bracket 120. Under the action of the driving component 600 and the transmission structure 300, the first movable component 110, the second movable component 120, and the third movable component 130 can drive the light source mounting structure 400 to move along several guide structures. The several guide structures can assist the light source mounting structure 400 to adjust its position more quickly and smoothly, so as to realize the reaction detection of multiple light source heights of the product to be tested.

[0046] It is understandable that the lifting assembly 200 includes a first movable assembly 110, a second movable assembly 120, and a third movable assembly 130 with identical structures in order to better support the light source mounting structure 400. While ensuring stable support of the light source mounting structure 400, more movable assemblies with identical structures can be provided.

[0047] In some specific embodiments of this utility model, the light source mounting structure 400 includes a plurality of pillars 410 and a platform frame 420 disposed on the plurality of pillars 410. A rib structure 430 is provided between each pillar 410 and the platform frame 420. The plurality of pillars 410 are connected to the first bracket 110 and the second bracket 120 through a plurality of guide structures 500. The platform frame 420 is connected to the movable ends of the first movable component 210, the second movable component 220 and the third movable component 230. The platform frame 420 is suitable for placing the light source.

[0048] Reference Figure 3 As shown, in this embodiment, four support columns 410 are provided, and the platform frame 420 is a rectangular frame. The support columns 410 are located at the four corners of the platform frame 420. Each support column 410 and the platform frame 420 is provided with a rib structure. Each support column 410 on the left is connected to a guide structure 500 and a second bracket 120, and each support column 410 on the right is connected to a guide structure 500 and a first bracket 110. The arrangement of the support columns 410 can better support the weight of large light source equipment to be installed on the light source mounting structure 400. The arrangement of the platform frame 420 is conducive to better installation and support of the light source, and the rib structure 430 can even support greater weight. It can be understood that the number of guide structures 400 is the same as the number of support columns 410, and the number of ribs between each support column 410 and the platform frame 420 can also be two, three, or four, etc.

[0049] In some specific embodiments of this utility model, each guide structure 500 includes a slider 510 and a guide rail 520. Several guide rails 520 are respectively disposed on the first support 110 and the second support 120. One end of the slider 510 is fixedly connected to the support column 410, and the other end of the slider 510 is movably connected to the guide rail 520.

[0050] Reference Figure 3 As shown, in this embodiment, the guide structures 500 are four guide rod slider structures, which can provide a high degree of guidance. It is understood that the guide structures 500 can also employ other high-precision guiding devices, such as guide rod sliders, gear guides, and roller guides, etc., depending on the situation.

[0051] In some specific embodiments of this utility model, the transmission structure 300 includes a drive wheel 310 and a transmission belt 320. The drive wheel 310 is connected to two driven wheels 330 through the transmission belt 320. The drive wheel 310 is fixedly installed on the fixed end of the first movable component 210. The two driven wheels 330 are respectively fixedly installed on the second movable component 220 and the third movable component 230. The drive wheel 310 and the driven wheels 330 are at the same height.

[0052] Reference Figure 5 and Figure 6 As shown, in this embodiment, the driving wheel 310 and the driven wheel 330 have identical structures, improving the interchangeability of the transmission structure 300. It can be understood that the driving wheel 310 is determined by whether a driving component 600 is provided above it. By using a conveyor belt 320 for power transmission, a simple and easy-to-understand power transmission method is achieved, making operation convenient and quick.

[0053] In some specific embodiments of this utility model, the transmission structure 300 further includes a first adjusting wheel 340 and a second adjusting wheel 350 with identical structures. The first adjusting wheel 340 and the second adjusting wheel 350 are connected by a transmission belt 320. A first connecting member 360 is provided at the bottom of the first adjusting wheel 340. The first connecting member 360 is provided with a long groove 361. The first connecting member 360 is connected to the second bracket 120 through the long groove 361. The first adjusting wheel 340 can tighten or loosen the transmission belt 320 along the direction of the long groove 361. The second adjusting wheel 350 is provided on the second bracket 120. The first and second adjusting wheels 340 and 350 are located between the driving wheel 310 and the driven wheel 330. The driven wheel 330, the first adjusting wheel 340 and the second adjusting wheel 350 are at the same height.

[0054] Reference Figure 2 , Figure 6 and Figure 7 As shown, in this embodiment, the first adjusting wheel 340 and the second adjusting wheel 350 are connected by a transmission belt 320. They jointly control the tension of the transmission belt 320. The first adjusting wheel 340 is connected to the first connecting member 360, which is connected to the first bracket 110 through a long groove 361. This allows the first adjusting wheel 340 to move left and right, changing the tension of the transmission belt 320 and achieving precise adjustment of the transmission belt 320, thus improving the working efficiency and stability of the transmission structure 300. The second adjusting wheel 350 is fixed to the second bracket 120, assisting the first adjusting wheel 340 in completing the tension and relaxation adjustment, and making the connection between the transmission belt 320 and the driven wheel 330 tighter, resulting in smoother force transmission. It is understood that the first adjusting wheel 340 and the second adjusting wheel 350 have the same structure, improving the interchangeability of the transmission structure 300.

[0055] In some specific embodiments of this utility model, the first movable component 210 includes a rotating shaft 211, a first bearing 212, a second bearing 213, a second connecting member 214, a third connecting member 215, and a fourth connecting member 216. The rotating shaft 211 includes a continuous first connecting segment 2111, a second connecting segment 2112, and a third connecting segment 2113. The first connecting segment 2111 is fixedly connected from bottom to top to the first bearing 212, the fourth connecting member 216, the drive wheel 310, and the drive member 600. The lower end face of the inner ring of the first bearing 212 is connected to the second bearing 213. The upper end face of the connecting section 2112 is in contact with each other, the upper end face of the inner ring of the first bearing 212 is in contact with the lower end face of the fourth connecting member 216, the side of the outer ring of the first bearing 212 is connected to the first bracket 110, the second connecting section 2112 is connected to the second connecting member 214 by thread, the second connecting member 214 is fixedly installed on the platform frame 420, the second bearing 213 is set in the third connecting member 215, the third connecting section 2113 passes through the second bearing 213 and the third connecting member 215, and the third connecting member 215 is fixedly installed on the first bracket 110.

[0056] Reference Figure 4 and Figure 5 As shown, in this embodiment, the cross-section of the second connecting segment 2112 is larger than that of the first connecting segment 2111 but not larger than that of the outer ring of the first bearing 212, so that the inner ring of the first bearing 212 can rest against the shoulder of the second connecting segment 2112 and rotate together, while the outer ring of the first bearing 212 remains stationary and connected to the first bracket 110. The first connecting segment 2111 and the third connecting segment 2113 have the same cross-sectional size, which facilitates the design and processing of the rotating shaft 211, and allows the installation of the first bearing 212 and the second bearing 213 of the same size and type, thereby increasing the interchangeability of the first movable component 210.

[0057] It is understandable that the cross-sectional areas of the first connecting segment 2111 and the third connecting segment 2113 can be different. It is also understandable that, because the first bearing 212 needs to support the first connecting member 360 and the drive wheel 310, the first bearing 212 needs to be selected with a certain load-bearing capacity, such as a tapered roller bearing, ball bearing, or skew roller bearing. Furthermore, it is understandable that, when the first bearing 212 can be installed on the first bracket 110, the cross-sectional area of ​​the second connecting segment 2112 does not need to be larger than that of the first connecting segment 2111 and the third connecting segment 2113.

[0058] The second connecting section 2112 is provided with threads, which cooperate with the second connecting piece 214 to form a screw and nut type structure, making the overall transmission simple and convenient, and enabling more precise control. It can be understood that the length of the second connecting section 2112 is the distance that the light source mounting structure 400 can be adjusted.

[0059] The use of the second bearing 213 allows the third connecting section 2113 to remain fixedly connected to the third connecting member 215 while rotating. The third connecting member 215 ensures the fixed connection between the rotating shaft 211 and the first bracket 110. The fourth connecting member 216 supports the transmission structure 300, preventing contact between the transmission structure 300 and the base frame 100, thus ensuring smooth transmission.

[0060] In some specific embodiments of this utility model, the third connector 215 is also provided with a limiting structure 2151, which can clamp or loosen the third connector 2113.

[0061] Reference Figure 5 and Figure 6 As shown, in this embodiment, the limiting structure 2151 is a clamping structure. When the limiting structure 2151 clamps, it can restrict the rotational movement of the third connecting segment 2113, thereby fixing the light source mounting structure 400. It is understood that the limiting structure 2151 and the driving component 600 can be provided only on the first movable component 210. This arrangement ensures that the force generated between the limiting structure 2151 and the driving component 600 only acts on the first movable component 210 and is not transmitted to other components, effectively improving the service life of other components. Furthermore, using a single limiting structure 2151 can effectively cooperate with the driving component 600, making the device structure simpler. It is understood that the limiting structure 2151 and the driving component 600 can also be provided on the second lifting component 500 or the third lifting component 600.

[0062] In some specific embodiments of this utility model, the driving component 600 is a handwheel, and the driving component 600 is fixedly connected to the first connecting section 2111. The driving component 600 can drive the first movable component 210 to rotate along the central axis.

[0063] Reference Figure 4 As shown, in this embodiment, the handwheel 400 makes adjusting the light source mounting structure 400 simpler and easier to operate, and facilitates real-time adjustment. It is understood that the drive component 600 can also be driven by a motor, hydraulically, or pneumatically, etc.

[0064] In some specific embodiments of this utility model, a measuring component 700 is also included. The measuring component 700 includes a measuring scale 710 and a reading pointer 720. The measuring scale 710 is disposed on the first support 110 and has vertical scale markings. The reading pointer 720 is disposed on the support column 410 near the measuring scale 710 and can point to the scale markings on the measuring scale 710.

[0065] Reference Figure 8As shown, in this embodiment, the scale measurement data on the measuring scale 710 is the distance to the bottom surface of the first support 110. When the light source mounting structure 400 is located at the lowest position relative to the base frame 100, the reading pointer 720 points to the lowest scale measurement data on the measuring scale 710, and as the light source mounting structure 400 rises, the reading pointer 720 also moves upward and points to a higher scale measurement data.

[0066] Understandably, when using the device, the product under test is placed on the bottom surface of the base 100, and the height data of the distance between the light source mounting structure 400 and the product under test can be directly read through the reading pointer 720. Understandably, the measuring scale 710 can also be set on the second support 120, and the reading pointer 720 is correspondingly set on the stand 410 near the second support. Understandably, the reading pointer 720 can also be set on the slider 510, and can also move up and down with the light source mounting structure 400, pointing to the scale measurement data on the measuring scale 710.

[0067] It is understandable that when the first bracket 110 is installed on other devices and the product under test is not placed on the bottom surface of the first bracket 110, the displacement data when adjusting the light source mounting structure 400 can still be obtained through the measuring component 700, thereby calculating the height position distance between the product under test and the light source mounting structure 400.

[0068] This utility model embodiment also discloses a testing device, including the above-mentioned light source lifting and adjusting module.

[0069] During product testing, the product to be tested is placed on the bottom surface of the light source lifting and adjustment module. The light source lifting and adjustment module is suitable for supporting and installing the light source, and can quickly and smoothly adjust the position and height of the light source in real time, so as to realize the reaction detection of multiple light source heights of the product to be tested.

[0070] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
