Description

Technical Field

[0001] This application relates to the field of circuit board testing technology, and in particular to a performance testing carrier for lighting module circuit boards. Background Technology

[0002] Circuit boards are important electronic components, mainly consisting of electronic components and connectors. Electronic components (such as transistors, integrated circuits, resistors, and capacitors) are mainly used to realize circuit functions, while connectors (such as pin headers and sockets) are mainly used for connecting circuit boards to each other or to peripherals.

[0003] Circuit boards are the carriers for the electrical interconnection of electronic components. Currently, LED lighting modules generally adopt integrated circuit board designs. In order to ensure that LED lights can work continuously and stably, the performance testing of the LED lighting module needs to cover indicators such as voltage stability, solder joint conductivity, signal response speed, and temperature rise control.

[0004] In the early days of the industry, testing was usually carried out step by step by hand using a multimeter or a single-function tester, which was inefficient and prone to missing tests. Therefore, automated testing equipment has gradually become more popular in recent years. However, the general-purpose testing fixtures on the market often have poor compatibility, which can lead to poor contact during testing, resulting in large errors in the circuit board test data. Summary of the Invention

[0005] To address the issue of significant errors in circuit board test data caused by general-purpose testing fixtures, this application provides a performance testing carrier for lighting module circuit boards.

[0006] The technical solution adopted in this application for a performance testing fixture for a lighting module circuit board is as follows: A performance testing fixture for a lighting module circuit board includes a test base and a control panel. The test base has a vertical plate, an upper template slidably mounted on the vertical plate, and a lower template opposite to the upper template. The vertical plate has a driving component that drives the upper template closer to or further away from the lower template. The circuit board is placed on the lower template, which has a positioning component for fixing the circuit board's position. The upper template has a plug electrically connected to the control panel, and a fixing component for fixing the plug's position. The plug is for insertion and mating with a socket on the circuit board. The test base is hollow. The lower template includes a movable template and a stationary template, with a tension spring between them. Multiple extension plates are arranged between the movable and stationary templates, running along the direction from the movable template to the stationary template. The test base has expansion slots for the expansion plates to slide. The plate is inclined from top to bottom away from the static template. The extension plate closest to the static template is fixed on the static template. A slider is provided on one side of the extension plate, and a groove is opened on the other side for the sliders on adjacent extension plates to slide. A support plate is provided in the test seat to support the extension plate. A driving slope is opened at the bottom of the extension plate, and the driving slope is inclined from top to bottom away from the moving template. A push rod is slidably arranged on the test seat. The push rod is used to abut and slide with the driving slope. When the bottom edge of the driving slope of the extension plate abuts the push rod, the top of the extension plate is flush with the upper surface of the static template. A sliding slope is opened on the moving template, and the sliding slope is inclined from top to bottom towards the static template. The side of the extension plate away from the static template is used to abut and slide with the sliding slope. A moving rod is provided on the test seat to drive the push rod to slide.

[0007] By adopting the above technical solution, the testing personnel drive the push rod to slide using a moving rod. The sliding push rod first abuts against the driving inclined surface at the bottom of the expansion plate. As the push rod continues to slide, under the action of the slider and the slide groove, the push rod pushes the reaction force of the driving inclined surface, causing the expansion plate to tilt vertically upward until the edge of the driving inclined surface at the bottom of the expansion plate abuts against the push rod. At this time, the top of the expansion plate is flush with the upper surface of the stationary template. During this process, the side of the expansion plate facing away from the stationary template abuts against the sliding inclined surface on the moving template. Under the action of the reaction force of the expansion plate abutting against the sliding inclined surface on the moving template, the moving template slides away from the stationary template, and the tension spring is stretched, thereby completing the expansion of the lower template in the length direction, thus accommodating circuit boards of different lengths. At the same time, the expansion plate can support the bottom of the circuit board. The support reduces the possibility of deformation caused by local compression of the circuit board, which could lead to damage. This helps improve the accuracy of circuit board testing results. Next, the tester places the circuit board to be tested on the lower template and fixes its position using positioning components. Then, the plug is inserted into the socket on the circuit board. The upper template is then moved closer to the lower template using a driving component. Finally, the tester uses a fixing component to secure the plug to the upper template. The control panel detects the circuit board's performance indicators through the plug, completing the debugging process for this size circuit board. Afterward, a circuit board of the same specifications is placed on the lower template, and the upper template is used to drive the plug to be inserted into the socket on the circuit board fixed on the lower template, thus improving the compatibility with circuit boards of different sizes.

[0008] Optionally, the upper template includes a first mounting plate and a second mounting plate, with an isolation column between the first mounting plate and the second mounting plate. The second mounting plate is located below the first mounting plate, and the plug is arranged on the second mounting plate. Multiple buffer columns are vertically slidably inserted through the second mounting plate, and the multiple buffer columns are distributed on the second mounting plate. An anti-detachment plate is provided on the buffer column located between the first mounting plate and the second mounting plate. A rubber column is provided at the end of the buffer column facing away from the anti-detachment plate. The rubber column is used to abut against the circuit board, and a buffer compression spring supports the second mounting plate and the rubber column.

[0009] By adopting the above technical solution, as the second mounting plate approaches the circuit board, the adhesive column will first abut against the circuit board. As the second mounting plate continues to descend, the buffer spring is compressed, and the plug on the second mounting plate will gradually be inserted into the socket on the circuit board, thereby completing the electrical connection between the circuit board and the control panel, so that the control panel can directly detect the various performance characteristics of the circuit board.

[0010] Optionally, the driving component includes a push-pull quick clamp disposed on the upright plate, the first mounting plate is disposed on the top clamping head of the push-pull quick clamp, the test seat is provided with a column, and the second mounting plate is slidably sleeved on the column.

[0011] By adopting the above technical solution, when the testing personnel pull the handle of the push-pull quick clamp, under the guidance of the column, the clamping head of the push-pull quick clamp will drive the second mounting plate to slide synchronously through the first mounting plate. The second mounting plate will drive the plug to gradually approach the socket on the circuit board until the plug is plugged into the socket.

[0012] Optionally, the second mounting plate is made of steel, and the fixing component includes an adjustment seat. The plug is disposed on the adjustment seat, and the adjustment seat is provided with an electromagnet electrically connected to the control panel. The electromagnet is used to attract the plug onto the second mounting plate, and the attraction between the electromagnet and the second mounting plate is greater than the insertion and extraction force between the plug and the socket.

[0013] By adopting the above technical solution, the tester first plugs the plug on the adjustment seat into the socket on the circuit board. Then, the worker uses a push-pull quick clamp to gradually bring the second mounting plate closer to the circuit board until the bottom of the second mounting plate abuts against the adjustment seat. Then, the tester activates the electromagnet through the control panel. The electromagnet generates a magnetic force and fixes the adjustment seat on the second mounting plate, thus completing the precise adjustment of the plug position. This is beneficial to improving the compatibility with different circuit boards and improving the accuracy of plug-socket mating.

[0014] Optionally, the moving rod includes an ear plate disposed within the test seat, a screw rotatably disposed on the ear plate, a guide rod with an axis parallel to the screw arranged on the ear plate, a connecting block disposed on the push rod, the connecting block slidably sleeved on the guide rod, the connecting block being threadedly connected to the screw, a drive motor electrically connected to the control panel disposed on the ear plate, and the screw being coaxially disposed on the output shaft of the drive motor.

[0015] By adopting the above technical solution, the control panel starts the drive motor, and the output shaft of the drive motor drives the screw to rotate. Under the guidance of the guide rod, the rotating screw causes the push rod to slide along the axis of the guide rod through the connecting block, thereby enabling the push rod to push the extension plate to slide.

[0016] Optionally, the positioning component includes a corner plate and a side pressure block. One corner plate is rotatably disposed on both the moving template and the stationary template. The two corner plates are used to simultaneously restrict the circuit board on the moving template and the stationary template. Both the moving template and the stationary template are provided with abutment plates. A clamping post is slidably disposed on the abutment plate. The side pressure block is disposed on the clamping post. A clamping spring supports the side pressure block and the abutment plate. An anti-detachment block is disposed on the clamping post on the side of the abutment plate facing away from the side pressure block.

[0017] By adopting the above technical solution, after the moving template is adjusted, the inspector pulls the clamping column, which drives the side pressure block to press the clamping spring against the abutment plate. The clamping spring is compressed, and the inspector places the circuit board on the moving template and the stationary template. Then, the corner plate is rotated, which restricts the circuit board on the moving template and the stationary template. After that, the inspector releases the clamping column, the clamping spring returns to its original shape, and the side pressure block presses the side of the circuit board against the plate. The side pressure block and the corner plate are used to fix and position the circuit board, so that the plug can be smoothly inserted and removed from the socket.

[0018] Optionally, the moving template is provided with a guide rod, which slides in conjunction with the stationary template.

[0019] By adopting the above technical solution, the sliding direction of the moving template is guided and restricted.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The tester first places the circuit board to be tested on the lower template, then fixes the position of the circuit board with the positioning component, and then plugs the plug into the socket on the circuit board. Next, the upper template is moved closer to the lower template by the driving component. Finally, the tester fixes the plug on the upper template with the fixing component. The control panel detects the performance indication of the circuit board through the plug. At the same time, the debugging process of the circuit board of this size is completed. Then, a circuit board of the same specification is placed on the lower template, and the upper template is driven by the driving component to plug the plug into the socket on the circuit board fixed on the lower template, thereby improving the compatibility of circuit boards of different sizes. 2. The inspector first plugs the plug on the adjustment base into the socket on the circuit board. Then, the worker uses a push-pull quick clamp to gradually bring the second mounting plate closer to the circuit board until the bottom of the second mounting plate abuts against the adjustment base. The inspector then activates the electromagnet through the control panel. The electromagnet generates a magnetic force and fixes the adjustment base to the second mounting plate, thus completing the precise adjustment of the plug position. This helps to improve the compatibility with different circuit boards and improves the accuracy of plug-socket mating. 3. The inspector drives the push rod to slide using a moving rod. The sliding push rod first abuts against the driving ramp at the bottom of the extension plate. As the push rod continues to slide, under the action of the slider and the slide groove, the push rod pushes the reaction force of the driving ramp, causing the extension plate to tilt vertically upward until the edge of the driving ramp at the bottom of the extension plate abuts against the push rod. At this time, the top of the extension plate is flush with the upper surface of the stationary template. During this process, the side of the extension plate facing away from the stationary template abuts against the sliding ramp on the moving template. Under the action of the reaction force of the extension plate abutting against the sliding ramp on the moving template, the moving template slides away from the stationary template, and the tension spring is stretched, thereby completing the extension of the lower template in the length direction, thus accommodating circuit boards of different lengths. At the same time, the extension plate can support the bottom of the circuit board, reducing the possibility of the circuit board being locally compressed and deformed, which could lead to damage to the circuit board. This helps to improve the accuracy of the circuit board inspection results. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0029] This application discloses a performance testing carrier for lighting module circuit boards.

[0030] Reference Figure 1 A performance testing carrier for a lighting module circuit board includes a hollow test base 3, a control panel 4 bolted to the test base 3, a vertical plate 5 welded to the test base 3, an upper template 6 vertically slidably arranged on the plate 5, and a lower template 7 opposite to the upper template 6 arranged on the test base 3 and below the upper template 6, with the circuit board 1 placed on the lower template 7.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The upper template 6 is provided with a plug 10 that is electrically connected to the control panel 4. The plug 10 is used to connect and cooperate with the socket 2 on the circuit board 1. The upright plate 5 is provided with a driving component 8 that drives the upper template 6 to move closer to or further away from the lower template 7. The upper template 6 is provided with a fixing component 11 for fixing the position of the plug 10.

[0032] Reference Figure 1 and Figure 2The upper template 6 includes a first mounting plate 61 and a second mounting plate 62. The first mounting plate 61 is made of acrylic sheet as in the prior art, and the second mounting plate 62 is made of steel. An isolation column 63 is arranged between the first mounting plate 61 and the second mounting plate 62. The second mounting plate 62 is located below the first mounting plate 61. The plug 10 is arranged on the second mounting plate 62. Multiple buffer columns 64 are vertically slidably provided on the second mounting plate 62.

[0033] Reference Figure 1 and Figure 2 Multiple buffer posts 64 are distributed on the second mounting plate 62. Anti-detachment plates 65 are welded to the buffer posts 64 located between the first mounting plate 61 and the second mounting plate 62. A rubber post 66 is bolted to the end of the buffer post 64 facing away from the anti-detachment plate 65. The rubber post 66 is made of rubber material and is used to abut against the upper surface of the circuit board 1. A buffer spring 67 is provided between the second mounting plate 62 and the rubber post 66.

[0034] Reference Figure 2 The fixing component 11 includes an adjusting base 111, a plug 10 is bolted to the adjusting base 111, and an electromagnet 112 electrically connected to the control panel 4 is bolted to the adjusting base 111. The electromagnet 112 is used to attract to the lower surface of the second mounting plate 62. The attraction between the electromagnet 112 and the second mounting plate 62 is greater than the insertion and extraction force between the plug 10 and the socket 2. The second mounting plate 62 has a vertical through hole 14 for the power supply line to pass through.

[0035] Reference Figure 1 The driving component 8 includes a push-pull quick clamp 81 bolted to the upright plate 5. The push-pull quick clamp 81 is the prior art. The first mounting plate 61 is bolted to the top head of the push-pull quick clamp 81. A vertical column 82 is welded on the test seat 3. The second mounting plate 62 is slidably sleeved on the column 82.

[0036] After the circuit board 1 is fixed on the lower template 7, the inspector pulls the handle of the push-pull quick clamp 81. The clamping head of the push-pull quick clamp 81 will drive the second mounting plate 62 to approach the circuit board 1 through the first mounting plate 61. The second mounting plate 62 drives the buffer column 64 to descend synchronously until the glue column 66 abuts the upper surface of the circuit board 1. As the second mounting plate 62 continues to descend, the buffer spring 67 will be compressed, and the descent speed of the second mounting plate 62 will slow down.

[0037] As the second mounting plate 62 descends, it causes the plug 10 on the adjusting seat 111 to gradually connect to the socket 2 on the circuit board 1. Then, the testing personnel operate the control panel 4, which tests the circuit board 1 through the wires connected to the plug 10, thereby quickly obtaining various performance indices of the circuit board 1.

[0038] Reference Figure 3 , Figure 4 and Figure 5 The lower template 7 includes a movable template 701 and a stationary template 702. The movable template 701 and the stationary template 702 are provided with a placement groove 15 for placing the circuit board 1. A guide rod 13 is welded on the movable template 701. The guide rod 13 is slidably engaged with the stationary template 702. A tension spring 703 is arranged between the movable template 701 and the stationary template 702. The maximum size of the movable template 701 and the stationary template 702 after adjustment does not exceed the size of the first mounting plate 61.

[0039] Reference Figure 3 , Figure 5 and Figure 6 Multiple expansion plates 704 are arranged between the moving template 701 and the stationary template 702. The multiple expansion plates 704 are arranged sequentially along the direction from the moving template 701 to the stationary template 702. An expansion groove 705 is provided on the test seat 3 for the expansion plates 704 to slide.

[0040] Reference Figure 5 and Figure 6 The expansion plate 704 is inclined away from the static template 702 in a downward direction. The expansion plate 704 closest to the static template 702 is fixed on the static template 702. A slider 706 is welded to the side of the expansion plate 704 closest to the static template 702, and a groove 707 is opened on the other side for the slider 706 on the adjacent expansion plate 704 to slide.

[0041] Reference Figure 4 and Figure 5 The test seat 3 has an L-shaped support plate 708 welded to its inner top wall. The support plate 708 is used to support the extension plate 704. The bottom of the extension plate 704 has a driving slope 709. The driving slope 709 is inclined from top to bottom away from the moving template 701. A push rod 710 is slidably arranged inside the test seat 3. The push rod 710 is used to abut against and slide with the driving slope 709.

[0042] Reference Figure 5 When the bottom edge of the driving slope 709 of the extension plate 704 abuts against the upper surface of the push rod 710, the top plane of the extension plate 704 on the upper surface of the push rod 710 is flush with the upper surface of the static template 702. At the same time, the extension plate 704, which is flush with the upper surface of the static template 702, will detach from the support plate 708.

[0043] Reference Figure 5 The moving template 701 has a sliding inclined surface 711, which is inclined towards the stationary template 702 from top to bottom. The side of the extension plate 704 facing away from the stationary template 702 is used to abut against and slide with the sliding inclined surface 711.

[0044] Reference Figure 4The test base 3 is provided with a movable rod 12 that drives the push rod 710 to slide. The movable rod 12 includes an ear plate 121 welded to the top of the test base 3. A screw 122 is rotatably connected to the ear plate 121. A guide rod 123 with an axis parallel to the axis of the screw 122 is provided on the ear plate 121.

[0045] Reference Figure 4 A connecting block 124 is welded onto the push rod 710. The connecting block 124 is slidably sleeved on the guide rod 123. The connecting block 124 is threaded onto the screw rod 122. A drive motor 125, which is electrically connected to the control panel 4, is bolted onto the ear plate 121. The drive motor 125 is a forward and reverse motor in the prior art. The screw rod 122 is coaxially bolted onto the output shaft of the drive motor 125.

[0046] Reference Figure 3 The lower template 7 is provided with positioning components 9 for fixing the position of the circuit board 1. The positioning components 9 include corner plates 91 and side pressure blocks 92. One corner plate 91 is rotatably connected to both the moving template 701 and the stationary template 702. The two corner plates 91 are used to simultaneously restrict the circuit board 1 on the moving template 701 and the stationary template 702. Abutment plates 93 are welded on both the moving template 701 and the stationary template 702.

[0047] Reference Figure 3 A pressing post 94 is slidably inserted on the abutment plate 93, and a side pressing block 92 is welded to the pressing post 94. A pressing spring 95 supports the side pressing block 92 and the abutment plate 93. An anti-detachment block 96 is welded on the pressing post 94 on the side of the abutment plate 93 facing away from the side pressing block 92.

[0048] The inspector first measures the length of the circuit board 1 to be inspected, and then starts the drive motor 125 through the control panel 4. The output shaft of the drive motor 125 drives the screw 122 to rotate. Under the guidance of the guide rod 123, the rotating screw 122 drives the connecting block 124 to slide. The connecting block 124 drives the push rod 710 to slide synchronously along the axis of the guide rod 123.

[0049] The sliding push rod 710 first abuts against the driving inclined surface 709 at the bottom of the extension plate 704. As the push rod 710 continues to slide, under the action of the slider 706 and the groove 707, the push rod 710 pushes the reaction force of the driving inclined surface 709 to make the extension plate 704 tilt and slide vertically upward until the edge of the driving inclined surface 709 at the bottom of the extension plate 704 abuts against the push rod 710. At this time, the top of the extension plate 704 is flush with the upper surface of the static template 702.

[0050] During this process, the side of the expansion plate 704 facing away from the stationary template 702 will abut against the sliding inclined surface 711 on the moving template 701. Under the reaction force of the expansion plate 704 abutting against the sliding inclined surface 711 on the moving template 701, the moving template 701 slides away from the stationary template 702, and the tension spring 703 is stretched, thereby increasing the distance between the moving template 701 and the stationary template 702, so that the circuit board 1 with detection can be placed between the moving template 701 and the stationary template 702.

[0051] After the moving template 701 is adjusted, the inspector pulls the clamping column 94. The clamping column 94 drives the side pressure block 92 to press the clamping spring 95 onto the abutment plate 93. The clamping spring 95 is compressed. Then, the inspector places the circuit board 1 between the moving template 701 and the stationary template 702. At this time, the extension plate 704 can support the bottom of the circuit board 1.

[0052] The inspector rotates the corner plate 91, which restricts the circuit board 1 within the placement slots 15 opened on the moving template 701 and the stationary template 702. Then, the inspector releases the clamping column 94, presses the spring 95 to restore its deformation, and presses the side of the circuit board 1 against the side pressure block 92. The side pressure block 92 and the corner plate 91 are used to fix and position the circuit board 1. The inspector then plugs the plug 10 on the adjusting seat 111 into the socket 2 on the fixed circuit board 1.

[0053] Then, pull the handle of the push-pull quick clamp 81 so that the clamping head of the push-pull quick clamp 81 moves the second mounting plate 62 closer to the adjusting seat 111 until the second mounting plate 62 abuts against the upper surface of the adjusting seat 111. At this time, the tester supplies power to the electromagnet 112 through the control panel 4. The energized electromagnet 112 fixes the adjusting seat 111 and its plug 10 on the second mounting plate 62, thus completing the precise positioning of the plug 10.

[0054] The implementation principle of a lamp module circuit board performance testing carrier according to an embodiment of this application is as follows: the tester first measures the length of the circuit board 1 to be tested, and then starts the drive motor 125 through the control panel 4. The output shaft of the drive motor 125 drives the screw 122 to rotate. Under the guidance of the guide rod 123, the rotating screw 122 drives the connecting block 124 to slide. The connecting block 124 drives the push rod 710 to slide synchronously along the axial direction of the guide rod 123.

[0055] The sliding push rod 710 first abuts against the driving inclined surface 709 at the bottom of the extension plate 704. As the push rod 710 continues to slide, under the action of the slider 706 and the groove 707, the push rod 710 pushes the reaction force of the driving inclined surface 709 to make the extension plate 704 tilt and slide vertically upward until the edge of the driving inclined surface 709 at the bottom of the extension plate 704 abuts against the push rod 710. At this time, the top of the extension plate 704 is flush with the upper surface of the static template 702.

[0056] During this process, the side of the expansion plate 704 facing away from the stationary template 702 will abut against the sliding inclined surface 711 on the moving template 701. Under the reaction force of the expansion plate 704 abutting against the sliding inclined surface 711 on the moving template 701, the moving template 701 slides away from the stationary template 702, and the tension spring 703 is stretched, thereby increasing the distance between the moving template 701 and the stationary template 702, so that the circuit board 1 with detection can be placed between the moving template 701 and the stationary template 702.

[0057] After the moving template 701 is adjusted, the inspector pulls the clamping column 94. The clamping column 94 drives the side pressure block 92 to press the clamping spring 95 onto the abutment plate 93. The clamping spring 95 is compressed. Then, the inspector places the circuit board 1 between the moving template 701 and the stationary template 702. At this time, the extension plate 704 can support the bottom of the circuit board 1.

[0058] The inspector rotates the corner plate 91, which restricts the circuit board 1 within the placement slots 15 opened on the moving template 701 and the stationary template 702. Then, the inspector releases the clamping column 94, presses the spring 95 to restore its deformation, and presses the side of the circuit board 1 against the side pressure block 92. The side pressure block 92 and the corner plate 91 are used to fix and position the circuit board 1. The inspector then plugs the plug 10 on the adjusting seat 111 into the socket 2 on the fixed circuit board 1.

[0059] Then, pull the handle of the push-pull quick clamp 81 so that the clamping head of the push-pull quick clamp 81 moves the second mounting plate 62 closer to the adjusting seat 111 until the second mounting plate 62 abuts against the upper surface of the adjusting seat 111. At this time, the tester supplies power to the electromagnet 112 through the control panel 4. The energized electromagnet 112 fixes the adjusting seat 111 and its plug 10 on the second mounting plate 62, thus completing the precise positioning of the plug 10.

[0060] After replacing the circuit board 1 with one of the same specifications, once the circuit board 1 is fixed on the lower template 7 again, the inspector pulls the handle of the push-pull quick clamp 81. The clamping head of the push-pull quick clamp 81 will drive the second mounting plate 62 to approach the circuit board 1 through the first mounting plate 61. The second mounting plate 62 drives the buffer column 64 to descend synchronously until the glue column 66 abuts against the upper surface of the circuit board 1.

[0061] As the second mounting plate 62 continues to descend, the buffer spring 67 is compressed, slowing down the descent speed of the second mounting plate 62. As the second mounting plate 62 continues to descend, it will cause the plug 10 on the adjustment seat 111 to gradually connect to the socket 2 on the circuit board 1. Then, the testing personnel operate the control panel 4, which tests the circuit board 1 through the wires connected to the plug 10, thereby quickly obtaining various performance indices of the circuit board 1.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
