Description

Technical Field

[0001] This invention relates to the field of LED light strip testing, and in particular to an LED light strip power-on testing device. Background Technology

[0002] LED light strips are lighting products made by assembling LED chips on flexible printed circuit boards (FPCs) or rigid printed circuit boards (PCBs), named for their long, strip-like shape. They boast an ultra-long lifespan of 80,000 to 100,000 hours and possess core advantages such as energy efficiency, high performance, and environmental friendliness, thus gradually standing out in various decorative fields. Furthermore, their ability to be rolled and shaped flexibly allows for the creation of a wide variety of patterns and shapes, leading to their widespread application today.

[0003] In the production, distribution, and installation of LED light strips, power-on testing is a core process to ensure product quality and safety. It requires simulating actual working conditions to verify the light strip's light emission continuity, brightness uniformity, color temperature consistency, and electrical safety, in order to prevent products with problems such as open circuits, short circuits, or partial LED failures from entering the market.

[0004] Currently, the industry's power-on testing of LED light strips mainly relies on traditional manual operation: testers must first select an appropriate DC power supply based on the rated voltage (e.g., 12V, 24V) of the light strip under test, and then manually connect the positive and negative terminals of the power supply to the positive and negative terminals of the light strip through wires, terminals, or temporary soldering; after powering on, testers must visually observe whether the light strip emits light, whether there are dark areas or flickering phenomena, and judge whether the brightness and color temperature meet the standards based on experience. In some scenarios, it is necessary to use a multimeter to manually check the circuit voltage and current parameters.

[0005] Existing patent CN117783930B discloses an LED strip power-on testing device, comprising a base, a mounting frame and a test base fixedly mounted on the upper side of the base, the test frame fixedly mounted on the mounting frame and positioned directly above the test base, a test cylinder fixedly mounted on the upper side of the test frame, the bottom of the test cylinder being fixedly connected to a test plate via a piston rod passing through the test frame, and a test block fixedly mounted on the bottom of the test plate. This LED strip power-on testing device can automatically calibrate the LED strip to its optimal position using an adjustment component, achieving automatic calibration of the LED strip without requiring manual calibration, thus reducing the workload of operators. A positioning mechanism can fix and position the LED strip, while test probes are used to perform power-on testing, achieving automated power-on testing of the LED strip and effectively improving testing efficiency.

[0006] However, in actual operation, existing testing equipment requires testers to manually place each LED strip into the test position and conduct tests sequentially when testing in large batches. This manual operation not only leads to low testing efficiency but also increases labor intensity and is prone to introducing test errors due to inconsistent operation. To solve the above problems, an LED strip power-on testing device is proposed. Summary of the Invention

[0007] The purpose of this invention is to solve the problem that existing automated testing equipment still requires manual placement of LED light strips one by one to the testing position, resulting in high manual labor intensity and low testing efficiency during batch testing, which cannot meet the testing needs of large-scale production.

[0008] The present invention adopts the following technical solution:

[0009] An LED light strip power-on testing device includes a fixing frame and a feeding structure thereon. The front end of the fixing frame is also provided with a testing structure. Both the feeding structure and the testing structure are provided with loading structures. The testing structure is provided with a storage structure below it.

[0010] The feeding structure includes a feeding box with a feeding port on its upper surface. The inner side walls of the feeding box have corresponding inclined slide rails, with the slide rails on one side arranged in a serpentine pattern. Several sets of loading structures are installed on the slide rails. A discharge port is located at the end of the lowest slide rail, situated on the side wall of the feeding box. A lower pressure plate is installed at the bottom of the feeding box, connected to the feeding box by a supporting shaft. Limit frames and springs are also installed on the bottom surfaces of the lower pressure plate and the feeding box. The limit frames are flush with the supporting shaft. An extension plate is installed at the position where the lower pressure plate extends beyond the discharge port, with an L-shaped frame at the lower end of the extension plate for cooperation with the testing structure.

[0011] Furthermore, the slide rail has an L-shaped cross-section, with the vertical side away from the inner wall of the feeding box, for the loading structure to slide stably on the slide rail. The support shaft is located at one end near the discharge port, and the lower pressure plate rotates around the support shaft at an angle of 0-15°.

[0012] Furthermore, the test structure includes a test frame and a support frame. The support frame is mounted on a fixed frame, and a bearing seat is mounted on the support frame via an electric rotating shaft. A placement groove is provided in the middle of the bearing seat for placing the loading structure. Electric push rods controlled by an external controller are respectively provided at both ends of the placement groove. An inclined guide plate is provided on the side of the bearing seat near the discharge box for cooperating with the L-shaped frame and simultaneously supporting the loading structure discharged from the extension plate. A baffle is provided on the side of the bearing seat away from the guide plate to prevent the loading structure from sliding out.

[0013] Furthermore, a test support plate is provided in the middle of the test frame, and a foldable frame is provided on the test support plate. A test probe that cooperates with the loading structure is provided on the foldable frame. A telescopic cylinder facing downward is provided on the top of the test frame. A connecting plate is provided at the output end of the telescopic cylinder. An adjusting airbag is provided at the lower end of the connecting plate. An adjusting groove is provided on the lower surface of the adjusting airbag.

[0014] Furthermore, the loading structure includes a loading frame, the upper surface of which is provided with a limiting groove, the lamp strip body is provided in the limiting groove, the two sides of the loading frame are provided with positioning holes that cooperate with the electric push rod, the two ends of the lamp strip body are provided with test terminals that cooperate with the test probe, and the two ends of the bottom of the loading frame are provided with grooves for cooperating with the L-shaped section slide rail.

[0015] Furthermore, the adjusting airbag is located directly above the support seat, and the adjusting groove has inclined guide surfaces on both sides for pushing the light strip body inside the loading frame to move along the limiting groove to the middle position;

[0016] Furthermore, the regulating airbag is made of high-strength PVC mesh fabric, and the regulating airbag is detachably connected to the upper connecting plate. The regulating airbag is kept connected to an external air source to maintain the air pressure of the regulating airbag.

[0017] Furthermore, the storage structure includes a light strip storage box and a second storage box. The light strip storage box has an inclined unloading plate fixedly installed on the side facing the support seat to receive the light strip body falling from the loading frame. The second storage box is located directly below the support seat and is used to receive the loading frame falling from the support seat. The bottom surface of the second storage box has an inclined material gathering surface. The side wall of the second storage box at the bottom of the inclined material gathering surface is provided with a rack removal opening for removing the loading frame for reuse.

[0018] Furthermore, the electric rotating shaft is controlled by an external controller, the rotation angle range of the bearing seat is -15° to 90°, the folding of the folding frame is controlled by an external controller, the rotation angle range of the folding frame is 0° to 90°, the output end of the electric push rod is a cylindrical structure, and there are several electric push rods on each side, corresponding to the number of positioning holes on the loading frame.

[0019] The beneficial effects of this invention are:

[0020] The serpentine slide rails and the elastic pushing structure of the lower pressure plate enable continuous automatic feeding of the loading structure, eliminating the need for manual placement of each light strip, greatly reducing labor intensity and improving batch testing efficiency.

[0021] The automatic centering and calibration of the light strip is achieved by using the adjustment groove guide surface of the adjustment airbag, and the positioning of the loading frame is achieved by the electric push rod, which ensures that the test probe and the test terminal of the light strip make precise contact and avoids test errors caused by poor contact.

[0022] By adjusting the angle of the support, the light strip and the loading rack can be automatically separated after testing and stored in their respective storage boxes. The loading rack can be reused, simplifying the testing process and further improving the continuity of testing. Attached Figure Description

[0034] Example 1

[0035] This invention provides an LED light strip power-on testing device, including a fixing frame 1, a feeding structure 2, a testing structure 3, a loading structure 5, and a storage structure 4. The feeding structure 2 is mounted on the fixing frame 1, the testing structure 3 is set at the front end of the fixing frame 1, the loading structure 5 is configured on both the feeding structure 2 and the testing structure 3, and the storage structure 4 is installed below the testing structure 3.

[0036] The feeding structure 2 includes a feeding box 21. The feeding box 21 has a feeding port 22 on its upper surface. Corresponding inclined slide rails 23, arranged in a serpentine pattern, are provided on both internal side walls. The slide rails 23 have an L-shaped cross-section, with their vertical sides away from the inner wall of the feeding box 21. Several loading structures 5 are mounted on the slide rails 23. The bottom of the feeding box 21 is connected to a lower pressure plate 24 via a supporting shaft. A limiting frame 25 and a spring 26 are provided between the lower pressure plate 24 and the bottom surface of the feeding box 21. The limiting frame 25 is flush with the supporting shaft, ensuring the lower pressure plate 24... 4. When not under force, the spring 26 is not under force when the lower pressure plate 24 is horizontal. The support shaft is located at one end near the discharge port 27. The rotation angle of the lower pressure plate 24 around the support shaft is 0~15°. The end of the lowest slide rail 23 has a horizontal buffer platform to prevent the loading structure 5 from completely sliding out of the discharge box 21. The discharge port 27 is opened on the side wall of the discharge box 21 corresponding to the buffer platform. An extension plate 28 is set at the position where the lower pressure plate 24 extends out of the discharge port 27. An L-shaped frame is fixed at the lower end of the extension plate 28 for feeding materials in conjunction with the test structure 3.

[0037] The test structure 3 consists of a test frame 311 and a support frame 321. The support frame 321 is fixed on the fixed frame 1. A bearing seat 323 is installed on the support frame 321 via an electric rotating shaft 322. A placement groove 324 is opened in the middle of the bearing seat 323. Several electric push rods 325 controlled by an external controller are installed at both ends of the placement groove 324. An inclined guide plate 326 is set on the side of the bearing seat 323 near the material box 21. The guide plate 326 cooperates with the L-shaped frame to receive the loading structure 5 sent out by the extension plate 28. On the side of the bearing seat 323 away from the guide plate 326, there is a baffle to prevent the loading structure 5 from sliding out, thus preventing the loading frame 51 from sliding out of the placement groove 324. The electric rotating shaft 322 controls the rotation angle of the bearing seat 323 to be within the range of -15° to 90°.

[0038] A test support plate 312 is set in the middle of the test frame 311. A foldable frame 313 is installed on the test support plate 312. The foldable frame 313 is controlled by an external controller and has a rotation angle range of 0-90°. A test probe that cooperates with the loading structure 5 is mounted on the foldable frame 313. A telescopic cylinder 315 facing downward is installed on the top of the test frame 311. The output end of the telescopic cylinder 315 is connected to a connecting plate 316. An adjusting airbag 317 is set at the lower end of the connecting plate 316. The adjusting airbag 317 is made of high-strength PVC mesh fabric. It is detachably connected to the connecting plate 316 and connected to an external air source. An adjusting groove 318 is opened on the lower surface of the adjusting airbag 317. Inclined guide surfaces are provided on both sides of the adjusting groove 318. The adjusting airbag 317 is located directly above the bearing seat 323 and is used to calibrate the position of the light strip.

[0039] The loading structure 5 includes a loading frame 51. A limiting groove 52 is opened on the upper surface of the loading frame 51. A light strip body 54 is placed in the limiting groove 52. The length of the light strip body 54 is less than the length of the limiting groove 52. Test terminals are set at both ends of the light strip body 54. Positioning holes 53 are opened on both sides of the loading frame 51. The number of positioning holes 53 corresponds to and cooperates with the electric push rods 325 on the bearing seat 323 to achieve fixed positioning of the loading frame 51. Both ends of the bottom of the loading frame 51 are provided with grooves 55 for cooperating with the L-shaped section slide rail 23 to prevent the loading frame 51 from tilting on the slide rail 23 and ensure that the loading frame 51 slides stably on the slide rail 23.

[0040] The storage structure 4 includes a light strip storage box 41 and a second storage box 43. The side of the light strip storage box 41 facing the support 323 is fixed with an inclined unloading plate 42 for receiving the light strip body 54 after testing. The second storage box 43 is located directly below the support 323, and its bottom surface is provided with an inclined material gathering surface. The side wall of the second storage box 43 at the bottom of the material gathering surface is provided with a rack opening 44 for recycling the loading rack 51 for reuse.

[0041] Working principle:

[0042] During use, the LED strip body 54 to be tested is placed into the limiting groove 52 of the loading frame 51. Since the length of the LED strip body 54 is less than the length of the limiting groove 52, there is no need to deliberately adjust the position of the LED strip; it is sufficient that the LED strip is within the limiting groove 52. Several assembled loading frames 51 are then placed into the discharge port 22 of the feeding box 21. Under the action of gravity, the loading frames 51 slide downwards along the serpentine sliding rails 23 arranged on both sides. The outermost loading frame 51 rests on the buffer platform. During testing, the electric rotating shaft 322 is controlled. The bearing seat 323 is rotated counterclockwise by 15°, and the guide plate 326 on the bearing seat 323 abuts against the L-shaped frame 29, causing the lower pressure plate 24 to rotate around the support shaft by 15°. The loading rack 51 on the lower pressure plate 24 slides down along the inclined extension plate 28 onto the guide plate 326 and finally lands on the bearing seat 323. At the same time, the bearing seat 323 rotates in the opposite direction to return to its original position, and the spring 26 on the lower pressure plate 24 is stretched, causing the lower pressure plate 24 to return to the horizontal position. The second loading rack 51 enters the buffer platform, waiting for subsequent use.

[0043] The loading frame 51 on the support 323 is located in the placement groove 324. The electric push rod 325 in the placement groove 324 extends out and inserts into the positioning hole 53 of the loading frame 51 to fix the loading frame 51. The telescopic cylinder 315 is controlled to drive the adjusting airbag 317 to move down. The inclined guide surface of the adjusting groove 318 pushes the light strip body 54 to move along the limiting groove 52 to the middle position to achieve automatic calibration. The folding frame 313 is folded to the horizontal state. The test probe is aligned with the test terminal of the light strip body 54. The external controller starts the test program and performs power-on test through the test probe.

[0044] After the test is completed, the folding frame 313 is reset, the electric rotating shaft 322 controls the carrier seat 323 to rotate to 45°, the light strip body 54 slides into the light strip storage box 41 along the unloading plate 42, and continues to rotate to 90°. The electric push rod 325 retracts, the loading frame 51 falls from the carrier seat 323 into the second storage box 43, and after being collected by the material gathering surface, it is taken out from the rack opening 44 for reuse.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The various components mentioned in this invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
