Description

Technical Field

[0001] This application relates to the field of printed circuit board manufacturing technology, and in particular to PBA automatic testing equipment. Background Technology

[0002] Printed circuit boards (PCBs) serve as the "skeleton" of electronic devices, serving as crucial components that carry various electronic elements and enable circuit connections. Through pre-defined conductive lines, they connect components such as resistors, capacitors, and chips in an orderly manner, providing basic circuit support for the normal operation of electronic devices. On the basis of printed circuit boards, when various electronic components are assembled through processes such as soldering, a printed circuit board assembly (PBA) is formed, which is the core functional unit for electronic devices to achieve specific functions.

[0003] PBA integrates the circuitry of PCB with the functional characteristics of various electronic components. Its performance directly determines the operation of electronic devices. During the production of PBA, due to factors such as soldering process and component quality, defects such as poor soldering, short circuits, and abnormal brightness may occur in the light-emitting parts (such as LEDs, display modules, etc.). These defects will seriously affect the display function or signal transmission of the device. Therefore, it is necessary to test to determine whether there are problems with the light-emitting parts.

[0004] Currently, the industry's inspection methods for the light-emitting parts of PBAs are relatively traditional. Typically, the PBA is powered on and put into operation, then inspectors visually examine the light-emitting parts to determine if defects are present. However, this method is limited by the human eye's resolving power and subjective judgment, making it difficult to accurately identify subtle brightness deviations, localized dark spots, and other defects. This results in low inspection accuracy and can easily lead to defective products entering subsequent stages. Summary of the Invention

[0005] The purpose of this application is to address the problem of low detection accuracy in the manual testing of PBAs mentioned in the background art, where it is difficult to accurately identify some subtle brightness deviations, local dark spots, and other defects. This application provides an automatic PBA testing device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: The PBA automatic testing equipment includes a main unit, which has a visual testing structure for identifying PBAs inside, an anti-interference structure for preventing interference on the side of the main unit, a light-shielding structure for blocking PBAs inside the main unit, and a dust collection structure for removing dust from the surface of PBAs inside the main unit.

[0007] By adopting the above technical solution, the PBA testing equipment can test PBAs by using a visual testing structure in conjunction with an anti-interference structure and a light-shielding structure. The PBA testing equipment can achieve high-precision and high-efficiency PBA testing.

[0008] Furthermore, the main unit includes a base, a support frame fixed to the upper end of the base, an installation frame fixed to the upper end of the support frame, a protective door hinged to the side of the installation frame, a display panel installed on the protective door, a placement plate fixed to the upper end of the base, a placement slot for placing a PBA on the placement plate, and a power supply box installed on the side of the support frame.

[0009] By adopting the above technical solution, the main unit is used to support the entire testing equipment and to install the required structure.

[0010] Furthermore, the visual testing structure includes two mounting plates fixed inside the mounting frame. A servo motor is fixed to the upper end of one of the mounting plates. A first ball screw is rotatably connected between the two mounting plates. A first nut seat adapted to the first ball screw is sleeved on the first ball screw. A first guide rod is fixed between the two mounting plates. The first nut seat is slidably sleeved on the first guide rod. A visual recognition camera is fixed to the side of the first nut seat.

[0011] By adopting the above technical solution, the visual testing structure is used to capture images of PBA, and together with the testing system, the PBA is tested with high accuracy and efficiency.

[0012] Furthermore, a supplementary light is fixed to the top of the mounting frame.

[0013] By adopting the above technical solution, the supplementary light plays a supplementary lighting role, providing a good lighting environment for testing PBA, which is more conducive to testing PBA.

[0014] Furthermore, the anti-interference structure includes a first telescopic cylinder fixed inside the mounting frame, a telescopic belt fixed at the lower end of the mounting frame, a connecting plate fixed at the lower end of the telescopic belt, and the telescopic end of the first telescopic cylinder fixedly connected to the connecting plate.

[0015] By adopting the above technical solution, the anti-interference structure plays an anti-interference role, reducing the impact of environmental conditions such as external light sources on the accuracy of PBA testing.

[0016] Furthermore, the light-shielding structure includes two second telescopic cylinders fixed inside the base, and the telescopic ends of the two second telescopic cylinders are fixed with a lower pressure plate.

[0017] By adopting the above technical solution, the light-shielding structure is used to block the light-sensitive parts of the PBA, which facilitates testing the PBA display panel in a non-light-emitting state.

[0018] Furthermore, the collection structure includes a collection box fixed to the side of the support frame, a sealing side plate fixed to the upper side of the collection box, a through hole at the bottom of the collection box, a conveying pipe fixed to the upper end of the collection box, and a guide pipe fixed to the end away from the collection box. A support frame is fixed to the lower end of the mounting frame, the guide pipe is located inside the support frame, a suction pipe is fixed to the end of the guide pipe away from the conveying pipe, a collection component is provided inside the collection box, and an adjustment component is provided between the suction pipe and the support frame.

[0019] By adopting the above technical solution, the collection structure can collect dust and debris, reduce the obstruction of key parts of PBA caused by dust and debris, expose the parts to be tested, and thus improve the test accuracy.

[0020] Furthermore, the collection assembly includes a drive motor fixed to the side of the collection box, a drive shaft fixed to the output end of the drive motor, the end of the drive shaft away from the drive motor extending into the collection box and rotatably connected to the collection box, an impeller fixed to the end of the drive shaft extending into the collection box, and a collection net fixed inside the collection box.

[0021] By adopting the above technical solution, the collection component can generate negative pressure inside the collection box, thereby providing power for cleaning dust and debris from the surface and crevices of the PBA, allowing dust and debris to enter the collection box.

[0022] Furthermore, the adjusting assembly includes a second ball screw rotatably connected inside the support frame, the second ball screw extending out of the support frame, a second guide rod fixed inside the support frame, a second nut seat adapted to the second ball screw, the second nut seat slidably sleeved on the second guide rod, and a transmission component provided between the second ball screw and the drive shaft.

[0023] By adopting the above technical solution, the adjustment component can adjust the position of the suction pipe, increase the suction range of the suction pipe, and thus improve the cleaning effect on PBA.

[0024] Furthermore, the transmission component includes a first pulley fixed on the drive shaft, and a second pulley fixed at one end of the second ball screw extending out of the support frame. The first pulley and the second pulley are connected by a transmission belt.

[0025] By adopting the above technical solution, the transmission component plays a transmission role, enabling the bidirectional lead screw to rotate when the drive shaft rotates, thereby providing power for the movement of the vacuum cleaner pipe.

[0026] In summary, this application includes at least one of the following beneficial effects; 1. In this application, during use, the PBA to be tested is connected to the power supply box, enabling the PBA to be powered on. The PBA is then placed inside the placement slot, and the supplementary light is turned on. After being illuminated by the supplementary light, the display panel of the PBA illuminates. Image acquisition is then performed via a visual recognition camera, and the PBA is tested using a preset testing system. After the test, the second telescopic cylinder is activated. The retraction of the telescopic end of the second telescopic cylinder moves the lower pressure plate downwards, blocking the light inlet on the PBA and preventing the display panel from illuminating. Image acquisition is then performed again via a visual testing camera, and the test is conducted using the preset testing system. This testing device can replace manual testing, improving testing efficiency and accuracy.

[0027] 2. In this application, after the PBA to be tested is placed inside the placement slot, the extension end of the first telescopic screw extends, causing the connecting plate to move downward. When the moving plate moves, it causes the telescopic belt to extend, so that the connecting plate presses on the placement plate. By setting the telescopic belt, it can play an anti-interference role, reduce the influence of external light source and environmental conditions on PBA testing, and further improve the testing accuracy.

[0028] 3. In this application, before testing, the servo motor is started according to the size of the PBA to be tested, so that its output end rotates clockwise or counterclockwise. The servo motor drives the first ball screw to rotate. At this time, the first nut seat is subjected to force and is restricted by the first guide rod, so that the visual recognition camera moves up or down on the first ball screw, thereby adjusting the height of the visual recognition camera to a suitable height, so as to be applicable to PBAs of different sizes and improve the applicability range.

[0029] 4. In this application, when the first telescopic cylinder moves the connecting plate downwards, the drive motor operates, causing the drive shaft to rotate, which in turn rotates the impeller. During the impeller's rotation, a negative pressure is generated inside the collection box. Subsequently, under the action of the conveying pipe and the guide pipe, a negative pressure is generated at the lower end of the suction pipe. This negative pressure draws dust, debris, and other impurities from the gaps on the PBA surface into the collection box, where they fall onto the collection net, thus achieving the collection of dust and debris. By collecting dust and debris through this structure, the obstruction caused by dust and debris to critical parts of the PBA can be reduced, improving testing accuracy.

[0030] 5. As the drive shaft rotates, the first pulley rotates accordingly. Then, under the action of the transmission belt, the second pulley rotates. The rotation of the second pulley drives the second ball screw to rotate. When the second ball screw rotates, the second nut seat is subjected to force and is restricted by the second guide rod, causing the second nut seat to drive the suction pipe to move inside the support frame. As the suction pipe moves, it gradually passes through the PBA, thereby increasing the range of dust and debris collected by the suction pipe and improving the cleaning effect on the PBA.

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] This application discloses an automated PBA testing device.

[0035] Reference Figure 1 and Figure 2 The PBA automatic testing equipment includes a main unit, a visual testing structure for identifying PBAs inside the main unit, an anti-interference structure for anti-interference on the side of the main unit, a light-shielding structure for blocking PBAs inside the main unit, and a dust collection structure for removing dust from the surface of PBAs inside the main unit.

[0036] The main unit includes a base 1, a support frame 11 fixed to the upper end of the base 1, an mounting frame 12 fixed to the upper end of the support frame 11, a protective door 13 hinged to the side of the mounting frame 12, a display panel 14 mounted on the protective door 13, a placement plate 15 fixed to the upper end of the base 1, a placement slot 16 for placing the PBA on the placement plate 15, a power supply box 17 mounted on the side of the support frame 11, and a connecting wire mounted on the power supply box 17 for connecting the PBA to the power supply for subsequent testing.

[0037] Additionally, the visual testing structure includes two mounting plates 2 fixed inside the mounting frame 12. A servo motor 21 is fixed to the upper end of one of the mounting plates 2. A first ball screw 22 is rotatably connected between the two mounting plates 2. A first nut seat 23 adapted to the first ball screw 22 is sleeved on it. A first guide rod 24 is fixed between the two mounting plates 2. The first nut seat 23 is slidably sleeved on the first guide rod 24. A visual recognition camera 25 is fixed to the side of the first nut seat 23. A supplementary light 26 is fixed to the top of the mounting frame 12.

[0038] Furthermore, the anti-interference structure includes a first telescopic cylinder 3 fixed inside the mounting frame 12, a telescopic belt 31 fixed at the lower end of the mounting frame 12, the telescopic belt 31 is a corrugated plastic belt with telescopicity, which can move with the connecting plate 32, the lower end of the telescopic belt 31 is fixed to the connecting plate 32, and the telescopic end of the first telescopic cylinder 3 is fixedly connected to the connecting plate 32.

[0039] Furthermore, the light-shielding structure includes two second telescopic cylinders 33 fixed inside the base 1, and the telescopic ends of the two second telescopic cylinders 33 are fixed with a lower pressure plate 34.

[0040] In use, connect the terminal of the PBA to be tested to the connection wire of the power supply box 17 to power on the PBA. Then, place the PBA into the placement slot 16. After placement, the extension end of the first telescopic screw extends, causing the connecting plate 32 to move downward. When the moving plate moves, it causes the telescopic belt 31 to extend, so that the connecting plate 32 presses against the placement plate 15. Then, depending on the size of the PBA to be tested, start the servo motor 21 to rotate its output end clockwise or counterclockwise. The servo motor 21 drives the first ball screw 22 to rotate clockwise or counterclockwise. At this time, the first nut seat 23 is under force and is restricted by the first guide rod 24, so that the visual recognition camera 25 moves upward or downward on the first ball screw 22. The device moves downwards to adjust the height of the visual recognition camera 25 to a suitable height for PBAs of different sizes. Then, the supplementary light 26 is turned on. When the PBA under test is illuminated by the supplementary light 26, the display panel 14 lights up. The visual recognition camera 25 then captures images, and the PBA is tested using a preset testing system. After the test, the second telescopic cylinder 33 is activated. The retraction of the telescopic end of the second telescopic cylinder 33 moves the lower pressure plate 34 downwards, blocking the light inlet on the PBA and preventing the display panel 14 from emitting light. Images are then captured again by the visual testing camera, and the test is performed using the preset testing system. This testing device can replace manual testing, improving testing efficiency and accuracy.

[0041] Reference Figures 2-6 The collection structure 4 includes a collection box 41 fixed to the side of the support frame 11. A sealing side plate 42 is fixed to the upper side of the collection box 41. A through hole is opened at the bottom of the collection box 41. A conveying pipe 43 is fixed to the upper end of the collection box 41, and a guide pipe 44 is fixed to the end away from the collection box 41. A support frame 46 is fixed to the lower end of the mounting frame 12. The guide pipe 44 is located inside the support frame 46. A movable groove is provided on the side of the support frame 46. The upper end of the suction pipe 45 extends into the support frame 46 through the movable groove, and a rolling wheel is rotatably connected to the upper end of the suction pipe 45. The rolling wheel is slidably disposed inside the support frame 46 to serve as a guide. The suction pipe 45 moves inside the support frame 11, and the rollers rotate inside the support frame 46 to guide the movement of the suction pipe 45. The guide pipe 44 is a spring-loaded rubber tube with extensibility, which allows the suction pipe 45 to move inside the support frame 11. The suction pipe 45 is fixed to the end of the guide pipe 44 away from the delivery pipe 43. When the PBA is placed into the placement slot 16, the telescopic belt 31 is in a retracted state. At this time, the suction pipe 45 is located on the side of the placement slot 16. The collection box 41 is equipped with a collection component, and an adjustment component is provided between the suction pipe 45 and the support frame 11.

[0042] The collection assembly includes a drive motor 47 fixed to the side of the collection box 41. A drive shaft 471 is fixed to the output end of the drive motor 47. The end of the drive shaft 471 away from the drive motor 47 extends into the collection box 41 and is rotatably connected to the collection box 41. An impeller 472 is fixed to the end of the drive shaft 471 that extends into the collection box 41. A collection net 473 is fixed inside the collection box 41.

[0043] In addition, the adjustment assembly includes a second ball screw 48 rotatably connected inside the support frame 11. The first ball screw 22 is a bidirectional ball screw. The second ball screw 48 extends out of the support frame 11. A second guide rod 482 is fixed inside the support frame 11. A second nut seat 481 adapted to the second ball screw 48 is sleeved on it. The second nut seat 481 is slidably sleeved on the second guide rod 482. A transmission component is provided between the second ball screw 48 and the drive shaft 471.

[0044] Furthermore, the transmission components include a first pulley 49 fixed on the drive shaft 471, a second ball screw 48 extending out of the support frame with a second pulley 491 fixed at one end, and the first pulley 49 and the second pulley 491 being connected by a transmission belt 492.

[0045] When the first telescopic cylinder 3 moves the connecting plate 32 downward, the drive motor 47 operates, driving the drive shaft 471 to rotate, causing the impeller 472 to rotate. The rotation of the impeller 472 creates a negative pressure inside the collection box 41. Then, under the action of the conveying pipe 43 and the guide pipe 44, a negative pressure is created at the lower end of the suction pipe 45. Simultaneously, as the drive shaft 471 rotates, the first pulley 49 rotates accordingly. Then, under the action of the transmission belt 492, the second pulley 491 rotates. The rotation of the second pulley 491 drives the second ball screw 48 to rotate. When the second ball screw 48 rotates... This causes the second nut seat 481 to be under force and is simultaneously restricted by the second guide rod 482, causing the second nut seat 481 to drive the suction pipe 45 to move inside the support frame 11. As the suction pipe 45 moves, it gradually passes through the PBA, thereby sucking in dust, debris, and other impurities from the gaps on the surface of the PBA. These impurities then flow along the guide pipe 44 into the conveying pipe 43 and finally into the collection box 41, falling onto the collection net 473. By collecting dust and debris through the collection structure 4, the obstruction of critical parts of the PBA by dust and debris can be reduced, thus improving the testing accuracy. As the suction pipe 45 moves, when the second nut seat 481 moves to the end of the second ball screw 48, it will move back. When the connecting plate 32 contacts the placement plate 15, the first telescopic cylinder 3 stops working, and the drive motor 47 also stops working. At this time, the suction pipe 45 moves to the side of the placement slot 16, which facilitates the cleaning of the PBA to be tested next time without affecting the testing of the PBA, thus improving convenience. By setting up a movable suction pipe 45, the PBA can be thoroughly cleaned, improving the cleaning effect and making it more conducive to the testing of the PBA.

[0046] Working principle: When in use, connect the terminal of the PBA to be tested to the connection of the power supply box 17 to turn on the power to the PBA. Then put the PBA into the placement slot 16. After it is put in, the extension end of the first telescopic screw extends, which drives the connecting plate 32 to move downward. When the first telescopic cylinder 3 moves the connecting plate 32 downward, the drive motor 47 operates, driving the drive shaft 471 to rotate, causing the impeller 472 to rotate. The rotation of the impeller 472 creates a negative pressure inside the collection box 41. Then, under the action of the conveying pipe 43 and the guide pipe 44, a negative pressure is created at the lower end of the suction pipe 45. Simultaneously, as the drive shaft 471 rotates, the first pulley 49 rotates accordingly. Then, under the action of the transmission belt 492, the second pulley 491 rotates. The rotation of the second pulley 491 drives the second ball screw 48 to rotate. When the second ball screw 48 rotates... This causes the second nut seat 481 to be subjected to force, while being restricted by the second guide rod 482. This causes the second nut seat 481 to drive the suction pipe 45 to move inside the support frame 11. As the suction pipe 45 moves, it gradually passes through the PBA, thereby sucking in dust, debris and other impurities from the gaps on the surface of the PBA. The impurities then enter the conveying pipe 43 along the guide pipe 44 and finally enter the collection box 41, falling onto the collection net 473. The collection net 473 collects the dust and debris, which reduces the obstruction of key parts of the PBA by dust and debris and improves the testing accuracy. As the suction pipe 45 moves, when the second nut seat 481 moves to the end of the second ball screw 48, it will move back. As the connecting plate 32 moves, when the connecting plate 32 contacts the placement plate 15, the first telescopic cylinder 3 stops working, and the drive motor 47 also stops working. At this time, the suction pipe 45 moves to the side of the placement slot 16. This facilitates the cleaning of the PBA to be tested next time without affecting the testing of the PBA, thus improving convenience. When the connecting plate 32 contacts the placement plate 15, the servo motor 21 is activated according to the size of the PBA to be detected, causing its output end to rotate clockwise or counterclockwise. The servo motor 21 drives the first ball screw 22 to rotate clockwise or counterclockwise. At this time, the first nut seat 23 is subjected to force and is restricted by the first guide rod 24, causing the visual recognition camera 25 to move up or down on the first ball screw 22, thereby adjusting the height of the visual recognition camera 25 to a suitable height applicable to PBAs of different sizes. Then, the process is started. A supplementary light 26 illuminates the PBA (Personal Component Assembly) under test, causing its display panel 14 to light up. The image is then captured by a visual recognition camera 25 and tested using a pre-set testing system. After testing, a second telescopic cylinder 33 is activated. The retraction of the cylinder's extension end moves a lower pressure plate 34 downwards, blocking the light inlet on the PBA and preventing the display panel 14 from emitting light. The image is then captured again by a visual testing camera, and the test is performed using the pre-set testing system. This testing device can replace manual testing, improving testing efficiency and accuracy.
