Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to a non-transparent PCBA gold finger product automatic alignment test fixture. Background Art

[0002] When testing PCBA, PCBA testing equipment generally uses a power module to drive the upper module to press down on the PCBA placed in the carrier, so that the conductive touch pad of the upper module contacts the gold finger on the PCBA and is energized, thereby giving the PCBA a power-on test. However, during the test, if the PCBA is not aligned with the conductive touch pad of the upper module when it is placed in the carrier, or if the PCBA is displaced when the carrier is moving, the conductive touch pad will not be able to accurately contact the gold finger on the PCBA when it descends, which will seriously affect the test results. Utility Model Content

[0003] The utility model aims to provide a non-transparent PCBA gold finger product automatic alignment test fixture to solve the technical defects described in the background technology.

[0004] The non-transmissive PCBA gold finger product automatic alignment test fixture comprises a frame, the frame is equipped with a carrier plate and a camera frame, the carrier plate is provided with a product slot for placing the PCBA, one side of the product slot is provided with a positioning opening, the carrier plate is provided with a horizontal and vertical movement driving module, the horizontal and vertical movement driving module pushes a push plate member that can enter the positioning opening, the push plate member is provided with a conductive touch plate that can enter the product slot and the PCBA gold finger, the camera frame is provided with a visual positioning camera located above the product slot and identifying the position of the gold finger on the upper surface of the PCBA, and the horizontal and vertical movement driving module cooperates with the visual positioning camera;

[0005] According to the technical solution, after the PCBA is placed in the product slot, the visual positioning camera takes a picture of the gold finger on the upper surface of the PCBA to obtain the position information of the PCBA gold finger. The horizontal and vertical movement driving module drives the push plate to move until the conductive touch plate is aligned with the PCBA gold finger according to the position information. After that, the horizontal and vertical movement driving module drives the push plate to enter the positioning opening again, and the conductive touch plate then enters the product slot from the positioning opening and contacts the PCBA gold finger to be energized, so as to implement the power-on test of the PCBA. Therefore, the utility model has the following beneficial effects:

[0006] Before the conductive touch panel contacts the PCBA gold finger and is energized, the utility model obtains the gold finger position information on the upper surface of the PCBA through the visual positioning camera located above the product slot, and uses the horizontal and vertical movement driving module to drive the push plate to move according to the position information, so that the conductive touch panel is aligned with the PCBA gold finger. Therefore, when the PCBA is placed in the product slot, there is no need to deliberately align the PCBA with the conductive touch panel, and the conductive touch panel can also accurately contact the PCBA gold finger and be energized. At the same time, the utility model solves the problem that the conductive touch panel cannot accurately contact the PCBA gold finger due to displacement of the PCBA when the carrier is moving.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0037] like Figures 1 to 8As shown, this specific embodiment provides a non-transparent PCBA gold finger product automatic alignment test fixture, which includes a frame 1, and the frame 1 is equipped with a carrier board 2, a camera frame 4 and a lifting drive module 5.

[0038] The carrier board 2 is provided with a product slot 21 for placing the PCBA, a positioning opening 22 is provided on one side of the product slot 21 , and a material taking port 23 connected to the positioning opening 22 is provided at the bottom of the product slot 21 .

[0039] The carrier plate 2 is equipped with a transverse and longitudinal movement driving module 3, which includes a motor 32 and a push plate transverse slide rail 33. The motor 32 and the push plate transverse slide rail 33 are fixed on the carrier plate 2. The motor 32 drives a screw rod 34. A push plate slider seat 35 threadedly connected to the screw rod 34 slides on the push plate transverse slide rail 33. The push plate slider seat 35 is equipped with a longitudinal push cylinder 36 and a longitudinal slide rail 37. The longitudinal push cylinder 36 pushes a push plate member 30 that can enter the positioning opening 22. The push plate member 30 is equipped with a longitudinal movement slider 38, a reset spring 39 and a conductive touch plate 31. The longitudinal movement slider 38 cooperates with the longitudinal slide rail 37. One end of the reset spring 39 is connected to the push plate member 30, and the other end of the reset spring 39 is connected to the push plate slider seat 35. When the push plate member 30 enters the positioning opening 22, the conductive touch plate 31 is connected to the PCBA gold finger.

[0040] The camera frame 4 is provided with a crossbeam 44, on which a camera transverse slide rail 45 is installed, on which a camera slider seat 46 slides, and on which a locking plate 47 is provided for fixing to a certain position of the camera transverse slide rail 45. The locking plate 47 can be fixed to a certain position of the camera transverse slide rail 45 by means of screws, latches or buckles. The camera slider seat 46 is provided with a height slide optical adjustment frame 42 for adjusting the height of the visual positioning camera 41. The height slide optical adjustment frame 42 is provided with a distance slide optical adjustment frame 43 for adjusting the distance between the visual positioning camera 41 and the product slot 21. The distance slide optical adjustment frame 43 is provided with a visual positioning camera 41 located above the product slot 21. The visual positioning camera 41 is used to identify the gold finger position on the upper surface of the PCBA in the product slot 21, and the horizontal and vertical movement drive module 3 cooperates with the visual positioning camera 41.

[0041] The lifting drive module 5 drives a pressure plate 51. The lifting drive module 5 can choose to use a cylinder module, a screw module or a hydraulic module to drive the pressure plate 51 to rise and fall. When the lifting drive module 5 drives the pressure plate 51 to descend, it can press the conductive touch plate 31 to fit with the PCBA gold finger. The visual positioning camera 41 is tilted next to the pressure plate 51.

[0042] The following is the working process of the automatic alignment test fixture for non-transparent PCBA gold finger products:

[0043] After the PCBA is placed in the product slot 21, the visual positioning camera 41 takes a picture of the gold finger on the upper surface of the PCBA to obtain the position information of the PCBA gold finger. The motor 32 drives the screw rod 34 to rotate according to the position information. The screw rod 34 drives the push plate slider seat 35 to move on the push plate transverse slide rail 33. The push plate slider seat 35 drives the push plate member 30 to move so that the conductive contact plate 31 on the push plate member 30 is aligned with the PCBA gold finger. After that, the longitudinal push cylinder 36 pushes the push plate member 30 into the positioning opening 22, so that the conductive contact plate 31 enters the product slot 21 from the positioning opening 22 and contacts the PCBA gold finger and is energized. At this time, the lifting cylinder 36 pushes the lifting cylinder 36 to push the lifting cylinder 36 into the positioning opening 22, so that the conductive contact plate 31 enters the product slot 21 from the positioning opening 22 and contacts the PCBA gold finger and is energized. The driving module 5 drives the pressing plate 51 to descend, and the pressing plate 51 presses the conductive contact plate 31 to fit with the PCBA gold finger. After that, the PCBA is powered on for testing. After the test of the PCBA in the product slot 21 is completed, the lifting driving module 5 drives the pressing plate 51 to rise and reset, and the pressing plate 51 is separated from the conductive contact plate 31. After that, the longitudinal pushing cylinder 36 drives the push plate member 30 to move away from the positioning opening 22. At this time, the reset tension spring 39 simultaneously assists in driving the push plate member 30 to move away from the positioning opening 22 through the pulling force, so that the conductive contact plate 31 on the push plate member 30 is separated from the PCBA gold finger. After that, the PCBA that has completed the test is taken out of the product slot 21.

[0044] It should be understood that the above specific embodiments of the present invention are only used to exemplify or explain the principles of the present invention, and do not constitute a limitation to the present invention.
