Description

Technical Field

[0001] This invention relates to the field of LED strip fault prediction technology, and in particular to an automated testing device and method for LED strips. Background Technology

[0002] The widespread application of LED light strips has driven attention to their quality inspection, especially in pre-diagnosis and health management. To ensure proper equipment operation and extend its lifespan, fault prediction and health management technologies have been widely applied to light strip inspection; however, automated production processes often lack flexibility, and manual inspection is prone to errors and instability. Therefore, utilizing automated inspection devices to replace manual operation can improve inspection efficiency and accuracy.

[0003] A search revealed Chinese patent application CN203299359U, which discloses an LED strip testing station. The station includes a workbench with several fixed posts for winding LED strips, an LED strip testing power supply, and a frosted glass surface with a lighting fixture installed below it. The lighting fixture is an LED light group, composed of multiple LEDs connected in series and / or parallel. However, this patent only addresses the technical problem of inconvenient testing due to excessively long strips. In actual testing, some LED beads may be obstructed by the rotating wheel, making it impossible to measure their brightness. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the prior art, the automated LED strip inspection equipment and method provided by the present invention solves the technical problem that the contact point with the rotating wheel cannot be detected when the long LED strip is coiled up for inspection.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] Firstly, an automated LED strip light inspection device is provided, comprising an operating table with an overall rectangular structure. A fixed pulley is located at the center of one end of the upper surface of the operating table. Two centrally symmetrically distributed strip-shaped sliding holes are formed at the end of the operating table away from the fixed pulley. The extension direction of the two strip-shaped sliding holes is consistent with the length direction of the operating table. Vertical shaft tubes are slidably connected to each of the two strip-shaped sliding holes, and the two vertical shaft tubes move synchronously in opposite directions. A movable wheel 1 and a movable wheel 2 are respectively sleeved at the top of the two vertical shaft tubes, and the movable wheel 1 and movable wheel 2 are located on the front and rear sides of the center line of the fixed pulley, respectively. At two corners near the fixed pulley on the upper surface of the operating table, double rods and trapezoidal hooks are respectively provided. The trapezoidal hooks are equipped with tensioners and clamping mechanisms for fixing the LED strip body. The double rods are located near the rear corner. The LED strip body to be inspected starts from the double rods and sequentially passes around the movable rods. The movable wheel 1, fixed pulley, and movable wheel 2 are then fixed in the clamping mechanism. The area between the double rod and movable wheel 1 is the first stationary section, and the area between the clamping mechanism and movable wheel 2 is the second stationary section. The areas between the two sides of the fixed pulley and movable wheels 1 and 2 are the movable sections. Monitoring point 1 is set on the upper surface of the operating table located on the upper surface of the first stationary section, monitoring point 3 is set on the upper surface of the operating table located on the upper surface of the second stationary section, and monitoring point 2 is set on the upper surface of the operating table located on the upper surface of the movable section. By setting the light strip body in a zigzag shape above the operating table, the area of ​​the operating table can be saved for centralized detection. With the two movable wheels 1 and 2 that can move synchronously in opposite directions, the relative position of the light strip body in the movable section and monitoring point 2 can be moved when monitoring the brightness. The brightness of multiple points of the light strip body can be detected by a limited number of monitoring points 2.

[0007] A further feature of this invention is that the bottom ends of both vertical shafts are fixed with anti-detachment bearings, and the outer walls of the anti-detachment bearings are fitted with bearing fixing frames. The lower surface of the operating table, below each strip-shaped sliding hole, is provided with two horizontal guide rods aligned with the direction of the strip-shaped sliding holes. The sides of the bearing fixing frames are provided with sliding holes that form a sliding fit with the guide rods. Through the provided guide rods, it can be ensured that when the first and second movable wheels are subjected to the tension of the light strip body, the vertical shafts can still remain vertical and slide back and forth in the strip-shaped sliding holes, thereby preventing the light strip body from slipping off.

[0008] A further feature of this invention is that the first movable wheel, the second movable wheel, and the fixed pulley have the same thickness and are all in the same plane. The outer circumference of the first movable wheel, the second movable wheel, and the fixed pulley are all provided with anti-detachment grooves, and the width of the anti-detachment grooves is adapted to the width of the light strip body. The double rods include two vertical round rods with a gap between them, and the gap between the two round rods is adapted to the thickness of the light strip body. In use, the end of the light strip body with the rectifier can be quickly fixed, and disassembly is also convenient, improving the detection efficiency.

[0009] A further feature of this invention is that the equipment structures at monitoring points one, two, and three are identical, and the operating platform at each of these three monitoring points has an installation socket. Monitoring point one includes an adjusting column inserted into the installation socket. A stud is pre-installed at the bottom of the adjusting column, and a nut is screwed onto the bottom of the stud. A rectangular block is fixed to the top of the adjusting column, and an embedded hole is provided on the side of the rectangular block facing the light strip body. A photometer is embedded in the embedded hole, with the photometric surface of the photometer facing the emitting surface of the light strip body. Two parallel anti-detachment grooves are provided at the top of the rectangular block, and the extension direction of the anti-detachment grooves is perpendicular to the light strip body of the section being tested. The same anti-detachment lever is slidably connected to the two anti-detachment grooves, and parallel focusing plates are fixed to both ends of the anti-detachment lever.

[0010] A further feature of the present invention is that the tensioner includes a U-shaped hook, and an upwardly arched actuating rod is fixed to the top of the U-shaped hook. The trapezoidal hook includes two parallel pads, which are located on the front and rear sides of the tensioner, respectively. A protruding rod extending towards the middle and adapted to the U-shaped hook is fixed to each of the two pads. A tension spring is provided between the tensioner and the clamping mechanism.

[0011] A further feature of this invention is that the clamping mechanism includes a clamping block, and the clamping block is U-shaped with its opening away from the tension spring. The top of the clamping block has a U-shaped groove, and a notch for insertion is reserved near the bottom of the groove. A side hole is provided on the side of the clamping block away from the notch for insertion, and a self-locking nut is fixed in the middle of the side hole. A positioning bolt is screwed into the self-locking nut. A compression spring plate is provided in the side hole. When fixing the end of the light strip body without the rectifier, first pass its end through the notch for insertion and around the bottom of the U-shaped groove, then place its end against the surface of the compression spring plate, and then tighten the positioning bolt to fix the end of the light strip body.

[0012] A further feature of this invention is that racks symmetrically distributed on opposite sides of the two bearing fixing frames are respectively fixed. A rubbing mechanism is provided on the lower surface of the operating table between the two strip-shaped sliding holes. The rubbing mechanism includes an arched frame fixed to the lower surface of the operating table, with the opening of the arched frame facing upwards. A vertical rotating shaft is rotatably connected to the middle of the arched frame. A rotary gear one and a rubbing gear two are respectively fixed at the upper and lower ends of the rotating shaft. The rotary gear one meshes with both racks simultaneously. The two racks and the strip-shaped sliding holes rotate about the axis of rotation. The center lines of the shaft are centrally symmetrically distributed; the bottom end of the shaft is rotatably fitted with an anti-disengagement hook rod, and one end of the arched frame is fixed with a reduction motor. The top of the output shaft of the reduction motor is fixed with a wheel, and the lower surface of the wheel is rotatably connected to a toothed connecting rod near the circumferential edge. The toothed connecting rod passes through the gap between the anti-disengagement hook rod and the second rubbing gear and meshes with the second rubbing gear. This arrangement allows the first rotary gear to rotate intermittently in both directions after the reduction motor is started, which in turn drives the first movable wheel and the second movable wheel above the operating table to move in the opposite direction.

[0013] A further feature of this invention is that a corrosive agent generator is fixed to the lower surface of the operating platform away from the fixed pulley, and an atomizing nozzle is provided on the upper surface of the operating platform above the corrosive agent generator. The liquid inlet of the atomizing nozzle is connected to the liquid outlet of the corrosive agent generator through a flexible tube. A detection cover is hinged to the upper part of the operating platform, and an observation window is provided on the front of the detection cover. A transparent plate is provided in the observation window, which can simulate the corrosion resistance test of the light strip body outdoors.

[0014] A further feature of this invention is that two horizontally extending rear extension trays are reserved on the rear side of the operating table, and support legs are provided on the lower surface of the operating table near the four corners. The tops of the four support legs are fixed with guardrails to ensure that the table surface is clean and facilitates loading and unloading operations.

[0015] Secondly, an automated detection method for LED light strips is provided, including the following steps:

[0016] Step 1: First, fix the end of the LED strip body with the ballast in the double rod. Then, wrap the LED strip body around the first movable wheel, the fixed pulley, and the second movable wheel in sequence and fix it in the clamping mechanism. Before winding, make sure that the light-emitting surface of the LED strip body faces the photometer. After winding, select the appropriate position of the protruding rod according to the specific length of the LED strip body to fix the U-shaped hook and keep the LED strip body taut.

[0017] Step 2: After covering the detection cover, the reduction motor can be turned on. At this time, the rotary gear one rotates intermittently in both directions, which in turn drives the movable wheel one and movable wheel two on the upper part of the operating table to move in the opposite direction. At this time, it also drives the light strip body in the middle section to move relative to the photometers on the two monitoring points two, and records and measures the brightness of multiple points with a limited number of detection points.

[0018] Step 3: Turn on the corrosive agent generator while keeping the geared motor running. At this time, corrosive gas or liquid droplets will be generated around the light strip body. After a period of acid etching, observe the surface corrosion to test its surface corrosion resistance and whether it can work normally under such conditions.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. By setting the LED strip body in a zigzag pattern above the operating table, the area of ​​the operating table can be saved and centralized detection can be facilitated. With the help of two movable wheels, namely movable wheel one and movable wheel two, which can move in opposite directions and synchronously, the relative position of the movable section of the LED strip body and the second monitoring point can be moved when monitoring the brightness. The brightness of multiple points of the LED strip body can be detected by a limited number of monitoring points two. Then, based on the brightness of each point, the change in the overall charging brightness of the LED strip body can be obtained.

[0021] 2. By using focusing plates that can move longitudinally on both sides of the photometer, the brightness of the moving section of the light strip can be measured without being affected by adjacent LEDs, thus improving the accuracy of the measurement.

[0022] 3. With the trapezoidal hook and tension spring, after the LED strip is wound, the U-shaped hook can be fixed at a suitable position of the protruding rod according to the specific length of the LED strip body. This keeps the LED strip body taut, making it easy to monitor its surface brightness and tensile strength. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] In this embodiment, refer to Figures 1-10This solution provides an automated LED strip light inspection device, which includes an operating table 1 with an overall rectangular structure. A fixed pulley 6 is located at the center of one end of the upper surface of the operating table 1. Two centrally symmetrically distributed strip-shaped sliding holes 101 are opened at the end of the operating table 1 away from the fixed pulley 6. The extension direction of the two strip-shaped sliding holes 101 is consistent with the length direction of the operating table 1. Vertical shaft tubes are slidably connected to each of the two strip-shaped sliding holes 101, and the two vertical shaft tubes move synchronously in opposite directions. Movable wheels 1-3 and 2-13 are respectively sleeved at the top of the two vertical shaft tubes, and movable wheels 1-3 and 2-13 are located on the front and rear sides of the center line of the fixed pulley 6, respectively. At the two corners of the upper surface of the operating table 1 near the fixed pulley 6, double rods 5 and trapezoidal hooks 7 are respectively provided. The trapezoidal hooks 7 are equipped with tensioners 9 and clamping mechanisms 10 for fixing the LED strip body 20. The double rods 5 are located near the rear corner. The LED strip body 20 to be inspected starts from the double rods 5 and passes sequentially around movable wheels 1-3. The fixed pulley 6 and the movable wheel 13 are then fixed in the clamping mechanism 10. The area between the double rod 5 and the movable wheel 3 is the first stationary section, and the area between the clamping mechanism 10 and the movable wheel 13 is the second stationary section. The areas between the two sides of the fixed pulley 6 and the movable wheels 3 and 13 are the movable sections. The upper surface of the operating table 1 is provided with monitoring point 4 on the upper surface of the first stationary section, monitoring point 31 on the upper surface of the second stationary section, and monitoring point 8 on the upper surface of the upper surface of the movable section. By setting the light strip body 20 to be zigzag-shaped and coiled above the operating table 1, the area of ​​the operating table 1 can be saved for centralized detection. With the two movable wheels 3 and 13 that can move synchronously in opposite directions, the relative position of the light strip body 20 and the monitoring point 8 can be moved when monitoring the brightness. The brightness of multiple points of the light strip body 20 can be detected by a limited number of monitoring points 28.

[0036] Reference Figure 2 and Figure 4 The bottom ends of the two vertical shafts are fixed with anti-detachment bearings 18, and the outer walls of the anti-detachment bearings 18 are fitted with bearing fixing frames 19. The lower surface of the operating table 1 is provided with two horizontal guide slide rods 17 that are aligned with the direction of the strip slide holes 101 below each strip slide hole 101. The sides of the bearing fixing frames 19 are provided with slide holes that form a sliding fit with the guide slide rods 17. Through the guide slide rods 17, it can be ensured that when the movable wheel 1 3 and movable wheel 2 13 are subjected to the tension of the light strip body 20, the vertical shafts can still be kept vertical and slide back and forth in the strip slide holes 101, thereby preventing the light strip body 20 from slipping off.

[0037] Reference Figure 3The movable wheel 3, movable wheel 13, and fixed pulley 6 have the same thickness and are all in the same plane. The outer circumference of the movable wheel 3, movable wheel 13, and fixed pulley 6 are all provided with anti-detachment grooves. The width of the anti-detachment grooves is adapted to the width of the light strip body 20. The double rod 5 includes two vertical round rods with a gap between them. The gap between the two round rods is adapted to the thickness of the light strip body 20. In use, the end of the light strip body 20 with the rectifier can be quickly fixed. Disassembly is also convenient, which improves the detection efficiency.

[0038] Reference Figure 3 , Figure 4 and Figure 8 The equipment structures at monitoring points 1 (4), 2 (8), and 3 (11) are identical. The operating console 1 at each of these locations has a mounting hole 103. Monitoring point 1 (4) includes an adjusting column 406 inserted into the mounting hole 103. A stud is pre-installed at the bottom of the adjusting column 406, and a nut 405 is screwed onto the bottom of the stud. A rectangular block is fixed to the top of the adjusting column 406, and an embedded hole 401 is provided on the side of the rectangular block facing the light strip body 20. A photometer 402 is embedded in the embedded hole 401. The photometric surface faces the light-emitting surface of the light strip body 20. Two parallel anti-detachment grooves 407 are provided at the top of the rectangular block, and the extension direction of the anti-detachment grooves 407 is perpendicular to the light strip body 20 of the section being tested. The same anti-detachment lever 403 is slidably connected in the two anti-detachment grooves 407, and parallel focusing plates 404 are fixed at both ends of the anti-detachment lever 403. By setting the focusing plates 404 on both sides of the photometer 402 that can move longitudinally, the brightness of the light strip body 20 of the moving section can be detected without being affected by adjacent lamp beads, thus improving the detection accuracy.

[0039] Reference Figure 9 and Figure 10 The tensioner 9 includes a U-shaped hook, and an upwardly arched lever 22 is fixed to the top of the U-shaped hook. The trapezoidal hook 7 includes two parallel pads, which are located on the front and rear sides of the tensioner 9, respectively. A protruding rod extending towards the middle and adapted to the U-shaped hook is fixed on each of the two pads. A tension spring 21 is provided between the tensioner 9 and the clamping mechanism 10. Through the trapezoidal hook 7 and the tension spring 21, after the winding is completed, the U-shaped hook can be fixed at a suitable position of the protruding rod according to the specific length of the light strip body 20, thereby keeping the light strip body 20 taut and facilitating the monitoring of its surface brightness and tensile strength.

A side hole 1004 is provided on the side of the clamping block away from the plug-in notch 1002, and a self-locking nut 1003 is fixed in the middle of the side hole 1004. A positioning bolt rod is screwed into the self-locking nut 1003. A compression spring plate 1005 is provided in the side hole 1004. When fixing the end of the light strip body 20 without the rectifier, first pass its end through the plug-in notch 1002 and around the bottom of the U-shaped groove 1001, then attach its end to the surface of the compression spring plate 1005, and then tighten the positioning bolt rod to fix the end of the light strip body 20.

A rubbing mechanism 15 is provided on the lower surface of the operating table 1 between two strip-shaped sliding holes 101.

The two racks 16 and the strip-shaped sliding holes 101 are perpendicular to the center line of the rotating shaft 157. The components are centrally symmetrically distributed. The bottom end of the rotating shaft 157 is rotatably sleeved with an anti-detachment hook rod 158, and one end of the arched frame 151 is fixed with a reduction motor 154. The top of the output shaft of the reduction motor 154 is fixed with a rotating wheel 155.

The toothed connecting rod 156 passes through the gap between the anti-detachment hook rod 158 and the second rubbing gear 153 and meshes with the second rubbing gear 153. With this arrangement, after the reduction motor 154 is started, the first rotary gear 152 can be driven to rotate intermittently in both forward and reverse directions, which in turn drives the first movable wheel 3 and the second movable wheel 13 above the operating table 1 to move in the opposite direction.

The top of the four support legs is fixed with a guardrail to ensure that the table surface of the operating table 1 is clean and facilitates loading and unloading operations.

[0044] This solution also provides an automated testing method for LED light strips, including the following steps:

[0045] Step 1: First, fix the end of the LED strip body 20 with the rectifier in the double rod 5. Then, wrap the LED strip body 20 around the movable wheel 3, the fixed pulley 6, and the movable wheel 13 in sequence and fix it in the clamping mechanism 10. Before winding, make sure that the light-emitting surface of the LED strip body 20 faces the photometer 402. After winding, select the appropriate position of the protruding rod according to the specific length of the LED strip body 20 to fix the U-shaped hook and keep the LED strip body 20 taut.

[0046] Step 2: After covering the detection cover 2, the reduction motor 154 can be turned on. At this time, the rotary gear 152 rotates intermittently in both directions, which in turn drives the movable wheel 3 and movable wheel 13 on the upper part of the operating table 1 to move in the opposite direction. At this time, it also drives the light strip body 20 in the middle section to move relative to the photometer 402 on the two monitoring points 8, and records and measures the brightness of multiple points with a limited number of detection points.
