Description

Technical Field

[0001] This utility model relates to the field of LED module testing and processing, and specifically to an LED module thrust testing device. Background Technology

[0002] After the electronic components of an LED module are manufactured, the LED beads and parts of the module need to undergo thrust testing. Previously, this was mainly done manually using a force gauge. However, manual testing has certain problems, such as the inability to ensure that the measuring tip of the force gauge is perpendicular to the force-bearing surface of the LED module under test, which may lead to significant errors in the test results.

[0003] A module force measuring device, disclosed in publication number CN208921340 U, ​​includes a module force measuring mechanism and a module fixing mechanism. The module force measuring mechanism includes a force gauge and a worktable for adjusting the position of the force gauge. The module fixing mechanism is located at one end of the force gauge's measuring head. The worktable includes a worktable base, a first slider, a second slider, a first handwheel for driving the first slider to slide freely along the vertical direction of the worktable base, and a second handwheel for driving the second slider to slide freely along the horizontal direction of the worktable base. However, existing module force measuring devices have complex structures, and the module fixing mechanism clamps and fixes electronic components, making operation complicated when changing the detection position and reducing the efficiency of thrust testing. Summary of the Invention

One end of the positioning base has two slide rails arranged longitudinally along the base, parallel to each other. An X-axis and Y-axis adjustment mechanism is provided on each slide rail. The thrust tester is fixed to the X-axis and Y-axis adjustment mechanism. The other end of the positioning base has two clamping plates arranged laterally along the base: a first clamping plate and a second clamping plate. A certain distance exists between the first and second clamping plates, forming a workpiece inspection area. The first clamping plate is located near the X-axis and Y-axis adjustment mechanism. A second slider is provided at the lower end of the first clamping plate, slidingly engaging with the slide rails. A positioning groove is provided on the first clamping plate for the measuring head of the thrust tester to protrude.

[0007] Furthermore, the X-axis and Y-axis adjustment mechanism includes two first sliders, a ball screw, and a lifting adjustment screw. The first sliders are disposed on each of the slide rails, and a sliding bracket is mounted on each of the two first sliders. The sliding bracket is connected to the ball screw and is used to drive the sliding bracket to slide along the slide rail. The lifting adjustment screw is disposed at the upper end of the sliding bracket, and a thrust mounting plate is movably mounted on the sliding bracket through the lifting adjustment screw. The thrust tester is fixed on the thrust mounting plate.

[0008] Furthermore, the sliding bracket is provided with two lifting adjustment screws, which are located on both sides of the sliding bracket.

[0009] Furthermore, the positioning base includes a positioning plate and a base disposed at the lower end of the positioning plate. The positioning plate has a rectangular structure, and a strip groove for the sliding bracket to move is opened in the middle of the positioning plate. The two slide rails are installed on the upper end face of the positioning plate and are respectively located on both sides of the strip groove.

[0013] This utility model has a simple structure. The workpiece to be tested is placed on the workpiece testing area of ​​the positioning base. The lower end of the first clamping plate is provided with a second slider, which slides in cooperation with the slide rail.

[0018] See Figure 1 and Figure 2As shown, an LED module thrust testing device includes a thrust tester 1 and a positioning base 2 for mounting on a workbench. The positioning base 2 is placed directly on the workbench. In this specific embodiment, the positioning base 2 includes a positioning plate 2-1 and a base 2-2 disposed at the lower end of the positioning plate 2-1. The positioning plate 2-1 has a rectangular structure, and the base 2-2 is arranged circumferentially along the positioning plate 2-1. The base 2-2 is mounted on the lower end face of the positioning plate 2-1 by screws. A strip groove 2-3 for the sliding bracket to move is formed in the middle of the positioning plate 2-1. One end of the positioning base 2 is provided with two slide rails 3 longitudinally distributed along the strip groove 2-3 of the positioning base. The two slide rails 3 are arranged parallel to each other. In this specific embodiment, the two slide rails 3 are mounted on the upper end face of the positioning plate 2-1, and the two slide rails 3 are respectively located on both sides of the strip groove 2-3. The slide rail 3 is provided with an X-axis and Y-axis adjustment mechanism 4. The thrust tester 1 is fixed to the X-axis and Y-axis adjustment mechanism 4. The X-axis and Y-axis adjustment mechanism includes two first sliders 4-1, a ball screw 4-2, and a lifting adjustment screw 4-3. The first sliders 4-1 are arranged on each of the slide rails 3. A sliding bracket 4-4 is installed on each of the two first sliders 4-1. The sliding bracket 4-4 is connected to the ball screw 4-2. In this specific embodiment, the ball screw 4-2 is installed on the lower end face of the positioning plate 2-1. The ball screw 4-2 is used to drive the sliding bracket 4-4 to slide along the slide rail. The upper end of the sliding bracket 4-4 is provided with two lifting adjustment screws 4-3, which are located on both sides of the sliding bracket 4-4. A thrust mounting plate 4-5 is movably mounted on the sliding bracket 4-4 via the lifting adjustment screws 4-3. The thrust tester 1 is fixed to the thrust mounting plate 4-5 by screws. Possibly, the upper surface of the thrust mounting plate 4-5 is also provided with a positioning groove for positioning the thrust tester 1. In this specific embodiment: the sliding bracket 4-4 includes a crossbeam and a support. The two sides of the crossbeam are fixedly connected to the first slider, and the support is provided in the middle of the crossbeam. The support is used to fixally connect to the nut of the ball screw. The two sides of the support are provided with lugs, and the lifting adjustment screws are mounted on the lugs.

[0021] The working principle of this utility model:

[0022] The workpiece to be tested is placed on the workpiece testing area of ​​the positioning base. The second slider at the lower end of the first clamping plate drives the first clamping plate to move along the slide rail, thereby adjusting the distance between the first and second clamping plates to clamp the workpiece. This also facilitates the rapid testing of the LED beads and other parts of the workpiece's LED module. The ball screw drives the sliding bracket to move back and forth, thereby controlling the measuring head of the thrust tester to press against and release the workpiece. The lifting adjustment screw on the sliding bracket can be used to adjust the height of the thrust mounting plate, thereby adjusting the height of the thrust tester's measuring head to align with the part to be tested. The operation is simple and convenient, improving work efficiency.
