Description
Technical Field
[0001] This utility model relates to the field of LED digital product testing technology, and in particular to batch testing fixtures. Background Technology
[0002] LED digital product testing fixtures are specially designed tooling equipment used to automatically or semi-automatically test the electrical performance and display functions of LED digital tubes. This allows for rapid determination of product qualification, quick completion of functional verification, performance testing, or parameter calibration, thereby significantly improving testing efficiency, reducing labor costs, and ensuring the consistency of test results.
[0003] This type of test fixture consists of a base, a positioning mechanism, a testing mechanism, and a motion mechanism. When in use, the tester only needs to place the test sample in the slot on the base. The positioning mechanism of the test fixture will position the test sample, and the testing mechanism will be responsible for the test. After that, the results will be sent to the tester. However, this type of test fixture has extremely poor versatility and a narrow range of compatibility. It can only perform one-to-one testing of LED digital tubes, and the probes are easily damaged.

Detailed Implementation
[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] Reference Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a batch testing fixture, including a base 1, an outer shell 2 fixedly connected to the outer wall of the base 1, the outer shell 2 protecting the testing machine from external damage, a sliding mechanism 4 provided on the top left and right sides of the base 1, a base plate 8 provided on the top of the base 1, a batch testing mechanism 3 provided on the top of the base plate 8, a pushing component 7 provided on the top of the batch testing mechanism 3, responsible for pushing the probe 308 to perform testing, used for batch testing, a support component 5 provided on the front side of the outer shell 2 to prevent the sliding mechanism 4 from falling out, and a fixing component 6 provided on the inner wall of the outer shell 2, responsible for fixing and preventing it from falling off after the fixture bottom mold 301 has risen;
[0038] The batch testing mechanism 3 includes a fixture base mold 301, which is located on top of the base 1. A lifting assembly 302 is located at the bottom of the fixture base mold 301, used to raise and lower the fixture base mold 301. Multiple digital tube limiting slots 303 are provided on the left and right sides of the top front end of the fixture base mold 301; multiple digital tube limiting slots 304 are provided on the left and right sides of the top top; and multiple digital tube limiting slots 305 are provided on the left and right sides of the top rear end of the fixture base mold 301. The digital tube limiting slots 303, 304, and 305 are used to place test samples and limit the position of the digital tubes on the test samples to prevent incorrect placement and testing failure. A support plate 306 is provided on the top of the mold 301. The support plate 306 is used to provide support points for each device. The outer wall of the support plate 306 is fixedly connected to the inner wall of the outer shell 2. Probe limiting plates 307 are threadedly connected between adjacent support plates 306. Probe pins 308 are slidably connected to the top of multiple probe limiting plates 307. The probe pins 308 are responsible for testing. The probe limiting plates 307 are responsible for preventing the probe pins 308 from shaking during movement and testing. Springs 309 are provided on the outer wall of multiple probe pins 308. The springs 309 prevent the probe pins 308 from being damaged by excessive speed when they move. A power supply wire 310 is fixedly connected to the bottom of the outer wall of multiple probe pins 308. The power supply wire 310 is responsible for powering the probe pins 308 for testing.
[0039] Specifically, when testing is required, the test sample is first placed into the digital tube limiting slots 303, 304, and 305 on the bottom mold 301 of the fixture for positioning, to prevent incorrect placement of the LEDs in the test sample. If the digital tube is not positioned correctly for testing, the fixture base mold 301 will be raised by the lifting component 302. When it reaches the designated position, the fixture base mold 301 will stop rising. Then, the fixing component 6 will fix the fixture base mold 301 to prevent it from shaking during testing. After that, the probe 308 will be pushed out of the probe limit plate 307 by the push component 7. At this time, the probe limit plate 307 will prevent the probe 308 from shaking during movement and causing damage to the probe 308. When the probe 308 contacts the pin of the digital tube, the power supply wire 310 will power on the probe 308 for testing. After the test is completed, the power supply wire 310 will automatically de-energize, and the push component 7 will retract. The probe 308 will be slowly brought back by the spring 309. Then, the fixing component 6 will release the fixing of the fixture base mold 301, and then the fixture base mold 301 will descend together with the lifting component 302.
[0040] Reference Figure 7 and Figure 8 The sliding mechanism 4 includes a sliding block 401, which drives the bottom mold 301 of the fixture to slide. The bottom of the sliding block 401 is slidably connected to the top of the base plate 8. A limit block 402 is fixedly connected to the left side of the sliding block 401 to limit the sliding direction of the sliding block 401. A limit slider 403 is slidably connected to the bottom of the limit block 402. The bottom of the limit slider 403 is fixedly connected to the top front end of the base plate 8. A limit slider 404 is slidably connected to the top of the sliding block 401. The limit sliders 403 and 404 limit the sliding of the limit block 402 to prevent it from moving up and down. The left side of 4 is fixedly connected to the left side of the inner wall of the outer shell 2. The middle part of the limiting block 402 is slidably connected to the sliding shaft 405. The sliding shaft 405 further fixes the moving direction of the limiting block 402. The rear end of the sliding shaft 405 is fixedly connected to the slider shaft fixing plate 406, which is responsible for fixing the sliding shaft 405 to prevent tilting. The left side of the slider shaft fixing plate 406 is threadedly connected to the left side of the inner wall of the outer shell 2. The right side of the sliding block 401 is slidably connected to the limiting slider 407, which restricts the right side movement of the sliding block 401. The left side of the limiting slider 407 is rotatably connected to multiple pulleys 408 to prevent the sliding block 401 from tilting to the right when it moves.
[0041] Specifically, after the test sample is placed, when the sliding block 401 is pushed, the sliding block 401 moves together with the limiting block 402 because it is fixedly connected. The limiting block 402 moves along the limited direction of the limiting slider 403, the limiting slider 404 and the sliding shaft 405 to prevent the left side from shifting. The limiting slider 407 fixes the right side of the sliding block 401 to prevent it from shifting. The pulley 408 on the limiting slider 407 prevents the right side of the sliding block 401 from tilting when it moves. When the limiting block 402 reaches the designated position, it will stop moving because of the protrusion of the limiting slider 403. The sliding block 401 will also stop moving together with the limiting block 402.
[0042] Reference Figure 1 , Figure 6 and Figure 9 The lifting assembly 302 includes a lifting platform 3021 for vertical movement. The front side of the lifting platform 3021 is slidably connected to the front side of the inner wall of the base 1. The left and right sides of the rear end of the lifting platform 3021 are both meshed with gear 1 3022 to control the vertical movement of the lifting platform 3021. The outer walls of the two gear 1 3022 are both meshed with gear 2 3023 to control the rotation direction of gear 1 3022. The adjacent gear 2 3023 are rotatably connected with motor 3024 to determine the rise or fall of the entire lifting assembly 302. The bottom of the motor 3024 is fixedly connected to the inner wall of the base 1. The fixing component 6 includes multiple sliding blocks 601. Multiple inclined blocks 604 are fixedly connected to the inner wall of the outer shell 2. The bottom of the multiple sliding blocks 601 is slidably connected to the top of the corresponding inclined block 604. The top of the multiple sliding blocks 601 is slidably connected to inclined guide posts 602 to control the sliding of the sliding blocks 601. The top of the multiple inclined guide posts 602 is fixedly connected to rope retractors 603 to control the rising and falling of the inclined guide posts 602. The outer wall of the rope retractors 603 is fixedly connected to the inner wall of the outer shell 2. The support assembly 5 includes a support platform 501, which provides support for the sliding block 401. The top left and right sides of the support platform 501 are rotatably connected to the front left and right sides of the outer shell 2. The bottom of the support platform 501 is rotatably connected to a retractable rod 502, which can be easily retracted when not in use and can provide support when needed. The front left and right sides of the outer shell 2 are provided with storage slots 503 to fix the moving direction of the retractable rod 502. The bottom end of the retractable rod 502 is slidably connected to the inner wall of the storage slot 503.
[0043] Specifically, the motor 3024 rotates clockwise or counterclockwise, driving the gear 3023 to rotate. The gear 3023 then drives the gear 3022 to rotate, which in turn controls the ascent or descent of the elevator 3021. The inclined guide column 602 rises or falls via the rope retractor 603, controlling the sliding block 601. The sliding block 601 slides on the inclined block 604, and its engagement or disengagement with the inclined guide column 602 fixes or releases the fixture bottom mold 301. When opened, the support platform 501 supports the sliding block 401 to prevent it from falling off. The retractable rod 502 provides support to the support platform 501. When not needed, the retractable rod 502 can move along the storage groove 503 to retract the support platform 501.
[0044] Reference Figure 1 , Figure 2 and Figure 3 The base 1 has protective pads 11 fixedly connected to its four bottom corners to protect the bottom of the testing machine. The bottom of each protective pad 11 has multiple anti-slip grooves 12, with equal distances between them to prevent the testing machine from sliding and being damaged. The pushing assembly 7 includes multiple push blocks 701, the bottoms of which are slidably connected to the top of the support plate 306 to push the probe 308. Shrinking machines 702 are fixedly connected to the opposite sides of each push block 701 to provide power to the push blocks 701. The bottoms of the shrinking machines 702 are fixedly connected to the top of the support plate 306. An operation screen 9 is fixedly connected to the front of the outer casing 2 to activate the test and display data. A protective shell 10 is provided on the outer wall of the operation screen 9 to prevent damage to the screen. The top left and right sides of the protective shell 10 are rotatably connected to the top left and right sides of the front of the base 1.
[0045] Specifically, the protective pads 11 at the four corners of the base 1 protect the tester from shaking when it is running on the ground. The anti-slip grooves 12 at the bottom of the protective pads 11 prevent the tester from sliding. When the test starts, the pusher 701 pushes the probe 308 to move for testing, while the shrinking machine 702 provides power to the pusher 701 to shrink and expand. The operation screen 9 is responsible for starting the test and displaying the test data after the test. The protective shell 10 protects the operation screen 9 when the test is not in use, preventing damage to the screen of the operation screen 9.
[0046] Working principle: The test sample is placed into the digital tube limiting slot 1 303, digital tube limiting slot 2 304, digital tube limiting slot 305, and support plate 306. Then, the protective shell 10 is opened and the operation screen 9 is activated. Motor 3024 then outputs power, driving gear 2 3023 to rotate clockwise. Because gear 1 3022 and gear 2 3023 are meshed, gear 1 3022 will drive gear 2 3023 to rotate clockwise. Then, gear 1 3022 clockwise drives the lifting platform 3021 to move upwards. The rear elevator 3021 moves the fixture bottom mold 301 together. When it reaches the designated position, the elevator 3021 stops moving. Then, the rope retractor 603 starts to release the rope, and the inclined guide post 602 moves downward and contacts the sliding block 601, driving the sliding block 601 forward to hold the bottom of the fixture bottom mold 301 in place, thus stabilizing the fixture bottom mold 301 during testing. Then, the pusher block 701 pushes the probe 308 through the probe limiting plate 307, allowing the probe 308 to contact the LED of the test sample. The digital tube pins, spring 309 will provide elastic force to probe 308 when probe 308 moves forward to prevent it from moving too fast and damaging probe 308. Then the power line 310 will start to power probe 308 and start testing. After the test is completed, the data will be displayed on the operation screen 9. After the test is completed, the retraction machine 702 and probe 308 will be retracted. Rope take-up device 603 pulls back the rope and drives inclined guide post 602. Sliding block 2 601 moves down along inclined block 604. Gear 1 3022 and gear 2 3023 are driven by motor 3024 to rotate counterclockwise. Then the elevator 3021 will move down. Fixture bottom mold 301 and elevator 3021 descend together.
[0047] After placing the test sample, slide block 401 needs to be pushed into the outer shell 2. When pushing slide block 401, slide block 401 moves together with limit block 402 because it is fixedly connected. Limit block 402 will move along the direction of limit slider 403, limit slider 404 and slide shaft 405. Slider shaft fixing plate 406 fixes slide shaft 405. Limit slider 3 407 fixes the moving direction of slide block 401 to prevent deviation. The pulley 408 on limit slider 3 407 prevents slide block 401 from bulging when it moves. When it reaches the designated position, limit block 402 will stop moving because of limit slider 403. After the test is completed, slide block 401 can be pulled out after the jig bottom mold 301 has descended. However, the support platform 501 must be opened first to prevent the front end of slide block 401 from being too heavy when it comes out, which may damage the test sample.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
