Description

Technical Field

[0001] This invention relates to the field of light source testing, and in particular to a fully automatic adjustable bar combination light source illumination testing platform. Background Technology

[0002] Currently, when we conduct lighting tests and combine applications of combined strip lights (strip light sources), we use a traditional lighting platform. This platform uses four simple experimental stands to fix the strip lights, and steel rulers to adjust the distance and height between the light sources. The angle of the light sources is adjusted using U-shaped screws. The camera is fixed to the top bracket, and its height is adjusted using U-shaped screw slots. The drawback of this operation is that it leads to a large error in the relative position of the four light sources. It is difficult for the light paths of the combined light sources to be completely focused on a single center. Control is only possible through experience and visual perception, and the adjustment is particularly cumbersome. Since each adjustment relies on manual adjustment, the data collected from each test has a large error, resulting in a significant discrepancy between the test data and actual application. This has a significant impact on the experimental test structure and practical application. Furthermore, since the camera needs to be used for lighting and testing each time, its height must be manually adjusted. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a fully automatic adjustable bar combination light source illumination test platform, which realizes fully automated position adjustment, improves test accuracy, reduces experimental data discrepancies, and is simple and convenient to operate.

[0004] To achieve the above objectives, the present invention provides a fully automatic adjustable bar-shaped combined light source illumination testing platform, comprising:

[0005] The platform main seat has a lifting platform connected to it, and a first through hole is provided in the middle of the lifting platform.

[0006] A camera lens module is connected to a camera lens and drives the camera lens to move up and down. One end of the camera lens module is connected to the main platform base, and the other end of the camera lens module passes through the first through hole, so that the camera lens can pass through the first through hole for operation.

[0007] Several light adjustment mechanisms are arranged around the first through hole. Each light adjustment mechanism includes a front and rear adjustment module, an angle adjustment module on the front and rear adjustment module, and a clamping module on the angle adjustment module. The clamping module is provided with a clamping station for installing the light strip.

[0008] Furthermore, the platform main seat also includes a bottom plate and a top plate. A first lead screw and an optical shaft are respectively provided on the bottom plate and the top plate. A first lead screw nut is connected to the first lead screw and the first lead screw nut is fixed to the lifting platform. A linear bearing is connected to the optical shaft and the linear bearing is fixed to the lifting platform. A first lifting motor that is linked to the first lead screw is provided on the top plate.

[0009] Furthermore, the camera lens module includes a first fixed bracket, a linkage member fixed to the first fixed bracket, a first sliding seat connected to the linkage member, and a second drive motor fixed to the first sliding seat. The first sliding seat has a first mounting hole for mounting the camera lens, and the linkage member has linkage teeth. The second drive motor is connected to a helical gear that meshes with the linkage teeth. The second drive motor drives the first sliding seat to move up and down, achieving automatic focusing of the camera in vertical positions.

[0010] Furthermore, a limiting protrusion is provided on the linkage component, and dovetail tenons are formed on both sides of the limiting protrusion. A dovetail groove matching the dovetail tenon structure is provided on the first sliding seat. The dovetail tenon and dovetail groove interlocking method can play a good limiting role, avoiding left and right swaying during movement and ensuring the stability of the sliding operation of the first sliding seat.

[0011] Furthermore, the front-to-back adjustment module includes a front-to-back adjustment fixing seat fixed to the lifting platform and a third drive motor fixed to the front-to-back adjustment fixing seat. The front-to-back adjustment fixing seat is provided with a front-to-back guide shaft, a second lead screw, and a second sliding seat linked to the second lead screw. The front-to-back guide shaft is connected to both sides of the second sliding seat through bearings, and the second lead screw is connected to the third drive motor. The third drive motor drives the second lead screw to rotate, thereby causing the lifting platform to move up and down. This allows for precise control of the position of the light bar and the camera lens, effectively focusing the light path to a single center and improving detection accuracy.

[0012] Furthermore, a midpoint guide line is provided at the midpoint of the side wing of the second sliding seat, and a center scale is provided on the side wing of the front and rear adjusting fixed seat. The center scale helps testers find the platform's center convergence point more conveniently and accurately.

[0013] Furthermore, the angle adjustment module includes an angle adjustment seat fixed on the front and rear adjustment module and a fourth drive motor. An arc-shaped guide rail is formed on the angle adjustment seat, and an arc-shaped slider is slidably connected on the arc-shaped guide rail. The arc-shaped slider is linked with the fourth drive motor to achieve displacement.

[0014] Furthermore, a worm gear linked to the fourth transmission motor is provided on the angle adjustment seat. The worm gear has helical teeth, and the arc-shaped slider has an arc-shaped rack that meshes with the helical teeth. By driving the worm gear to rotate forward and backward by the motor, the arc-shaped rack drives the arc-shaped slider to move back and forth, which can realize automated operation and more precise control.

[0015] Furthermore, one side of the arc-shaped guide rail is inclined, and the other side of the arc-shaped guide rail is provided with a locking groove. One side of the arc-shaped slider is provided with an inclined groove that matches the inclined portion, and the other side of the arc-shaped slider is provided with a locking block that matches the locking groove. Through the cooperation of the inclined portion and the locking groove with the locking block, the arc-shaped slider and the arc-shaped guide rail are connected. This ensures that the arc-shaped slider does not wobble left or right during operation, guaranteeing that it can only move back and forth along the arc-shaped guide rail driven by the worm gear, resulting in better working stability.

[0016] Furthermore, the clamping module includes a clamping base and a wing screw. The clamping base is a frame with an opening on one side. The clamping station is located on the clamping base. A threaded hole for the wing screw to pass through is provided on the side wing of the clamping base. A clamping block is connected to the end of the wing screw. The clamping block is placed in the clamping station, and front and rear guide shafts are connected to both sides of the clamping block. By placing the strip light in the clamping station and then clamping it with the clamping block driven by the wing screw, this structure can accommodate strip lights of different sizes, thus improving its practicality.

[0017] Compared with existing technologies, the present invention has the following advantages: The structure of the present invention places the light strip to be tested onto the clamping module. The clamping module can flexibly adjust the size of the clamping area to adapt to light strips of different sizes. An angle adjustment module can adjust the angle rotation, and a front-to-back adjustment module can achieve high-precision displacement control. Several light strip adjustment mechanisms are fixed on a lifting platform. The platform moves up and down automatically via electrical control. The camera lens module at the top can move up and down and automatically focus via electrical control. Moreover, the front-to-back adjustment module is equipped with a center scale, which helps the testers find the center convergence point of the platform more conveniently and accurately. The entire platform is controlled by PLC and a display screen, thereby achieving fully automatic control of all modules of the entire platform. Attached Figure Description

The arc-shaped slider 323 is linked with the fourth drive motor 322 to achieve displacement. Specifically, a worm gear 324 linked with the fourth drive motor 322 is provided on the angle adjustment seat 321. The worm gear 324 is installed as follows: Figure 7 As shown, a hollow mounting space 3212 is provided inside the angle adjustment seat 321. Mounting through holes 3213 are provided on both sides of the mounting space 3212. One end of the worm gear 324 can be rotatably connected to the mounting through hole 3213. The output shaft of the fourth drive motor 322 passes through the mounting through hole 3213 on the other side and is connected to the worm gear 324.

[0043] In summary, the working principle of this invention involves placing the light strip 5 to be tested within the clamping station 331 of the clamping module 33, and locking the light strip 5 by driving the clamping block 334 with a wing screw 333. The light strip adjustment mechanism 3, composed of the front-to-back adjustment module 31, the angle adjustment module 32, and the clamping module 33, allows for adjustment of the front-to-back movement and angle rotation of a single light strip 5. Furthermore, the clamping module uses a screw and a linear bearing 151. The design of the clamping station 331 and the clamping block 334 allows for clamping light strips 5 of various shapes, widths, lengths, and sizes. The third drive motor 312 and the fourth drive motor 322 of the front-to-back adjustment module 31 and the angle adjustment module 32 both use geared motors, enabling high-precision control of angle and displacement. Through the controller 6, synchronous front-to-back movement and automatic angle control of the light strip 5 are achieved.

[0044] In this embodiment, four light adjustment mechanisms 3 are provided on the lifting platform 11. The lifting platform is raised and lowered by two first lead screws 14 in conjunction with linear bearings 151, thereby achieving simultaneous up and down control of the four light adjustment mechanisms 3. The two first lead screws 14 are connected by a synchronous pulley and synchronous belt module to achieve synchronous movement of the two first lead screw modules, driving the lifting platform 11 to move up and down linearly. One of the first lead screws 14 is connected to the first lifting motor 16 through a synchronous belt, so that the fully automatic up and down movement is achieved through electrical control. The first fixed bracket 21 at the top also adopts a gear and rack module combined with a reduction stepper motor design, so that the automatic up and down focusing function of the camera can be achieved through electrical control. Moreover, the center scale 3111 on the front and rear adjustment fixed seat 311 is laser-marked, which helps the tester to find the center convergence point of the platform more conveniently and accurately. The entire platform is controlled by PLC and display screen 7, so as to achieve fully automatic control of all modules of the entire platform.
