Description

Technical Field

[0001] The present application relates to the technical field of circuit board detection, and more specifically, to a circuit board point sensing test device. Background Art

[0002] The point sensing test methods for circuit boards mainly include the bed of nails test method and the double probe or flying probe test method; the bed of nails test method is a common circuit board test method, which connects to each detection point on the circuit board through a probe with a spring; the double probe or flying probe test method does not rely on the pin pattern mounted on a fixture or bracket. This method uses two or more probes mounted on a tiny, freely movable magnetic head, and the test points are directly controlled by CAD / Gerber data.

[0003] In the related art, in order to facilitate the picking and placing of circuit boards during detection, for example, the patent with the prior art publication number CN117074927B provides a PCB circuit board detection device, in which when the carrier is located at the pick-up and placement station, the second limit wall of the sliding member is connected to the limit block, and the sliding member drives the carrier to move to the test station so that the carrier abuts against the positioning member, at this time, there is a distance between the conductive probe and the PCB circuit board to be tested on the carrier; the second linkage member drives the sliding member to continue to move so that the limit block is separated from the second limit wall, and the second abutting wall of the sliding member moves toward the limit block until the conductive probe is pressed on the PCB circuit board to be tested on the carrier; and when the probe mounting member drives the conductive probe to move up and away from the PCB circuit board to be tested, the sliding member moves toward the direction of the pick-up and placement station so that the second limit wall moves toward the limit block, and the carrier remains stationary until the second limit wall abuts against the limit block, and the carrier can be pushed to leave the test station.

[0004] Although the above-mentioned prior art solution can facilitate the picking and placing of circuit boards by driving the carrier to move back and forth between the test station and the pick-and-place station through the sliding member, during the test process, a single circuit board to be tested needs to be placed on the carrier at the pick-and-place station, and then moved to the test station for testing. After the test is completed, the carrier is moved to the pick-and-place station to take out the circuit board, resulting in low testing efficiency. Summary of the invention

[0078] The staff loads the circuit board body 100 at a position far away from the upper conveyor platform 5 and the lower conveyor platform 6, places the board holes of the circuit board body 100 corresponding to each group of pins 21 on the rotating body 2, and drives the rotating body 2 to rotate by the driving mechanism 4 in the forward direction, so that the rotating body 2 can drive the circuit board body 100 to rotate to a horizontal state. At this time, the driving mechanism 4 runs in the reverse direction to drive the probe assembly 3 to operate, so that multiple elastic probes 31 detect the circuit board body 100. After the inspection is completed, if the circuit board body 100 is qualified, the linear mechanism 7 will not operate. If the circuit board body 100 is unqualified, the linear mechanism 7 will operate to push the upper conveyor platform 5 so that the circuit board body 100 on the rotating body 2 can fall to the lower conveyor platform 5. On the conveying platform 6, sponges are provided on the top of the upper conveying platform 5 and the lower conveying platform 6 to prevent the circuit board body 100 from being damaged. Then the driving mechanism 4 is operated forward again to drive the rotating body 2 to rotate, so that the circuit board body 100 that has been inspected falls onto the corresponding conveying platform, and drives the next circuit board body 100 to rotate to a horizontal state, and at the same time drives the circuit board body 100 on the upper conveying platform 5 or the lower conveying platform 6 to be transported. This equipment can classify and transport the circuit board bodies 100 that have been inspected.

[0088] The driving mechanism 4 drives the pulley B38 to rotate, the pulley B38 drives the rotating column 36 to rotate, the rotating column 36 drives the two cams 37 to rotate, so that the two auxiliary rollers 371 press the connecting plate 35 downward, so that the connecting plate 35 moves downward, drives the four connecting columns 33 to move downward, thereby drives the probe plate 32 to move downward, so that the elastic probe 31 can detect the circuit board body 100.

[0096] The two support columns 85 are respectively located on both sides of the bottom corners of the first rotating frame 22 and the support plate 25. When the driving mechanism 4 is running, it drives the rotating body 2 to rotate and drives the rotating frame 45 to rotate at the same time, so that the limiting roller 451 presses the limiting frame 81 downward, thereby driving the fixing rod 83 and its connected cross frame 84 and support column 85 to move downward and then move upward. When the rotating body 2 drives the circuit board body 100 at the top to remain horizontal, the corner of the support plate 25 and the bottom of the first rotating frame 22 is just located between the two support columns 85, so that the two support columns 85 can limit the rotating body 2 to prevent the rotating body 2 from being unstable when the equipment is running the probe assembly 3, thereby ensuring the stability and safety of the equipment during use.

[0097] It can be understood that in order to ensure that when the corresponding circuit board body 100 on a working surface of the rotating body 2 is rotated to a horizontal state for testing, the first rotating frame 22, the second rotating frame 24 and a corner of the support plate 25 are located between the two support columns 85, the first rotating frame 22, the second rotating frame and the corresponding support plate 25 are all arranged in regular positive odd-numbered (greater than 1) polygons; such as regular triangles, regular pentagons or regular heptagons.

[0098] In summary, when the circuit board point sensing test device disclosed in the embodiment of the present application is in use, the staff loads the circuit board body 100 at a position away from the upper conveyor platform 5 and the lower conveyor platform 6, and places the plate holes of the circuit board body 100 corresponding to each group of pins 21 on the rotating body 2, and drives the motor 41 in the forward direction. Under the unidirectional effect of the one-way bearing B421, the gear B42 is driven to rotate, thereby driving the gear A26 to rotate, thereby driving the connecting frame 221 and the first rotating frame 22 to rotate, and the first rotating frame 22 drives the second rotating frame 24 and the support plate 25 to rotate through five sliding columns 23, thereby rotating multiple groups of pins 21, thereby achieving the effect of driving the circuit board body 100 to rotate, and enabling the rotating body 2 to drive the circuit board body 100 to rotate to a horizontal state.

[0099] Then the driving motor 41 runs in the reverse direction, driving the pulley C43 to rotate, thereby driving the belt A44 to rotate, and driving the pulley B38 to rotate under the one-way effect of the one-way bearing A381, and the pulley B38 drives the rotating column 36 to rotate, and the rotating column 36 drives the two cams 37 to rotate, so that the two auxiliary rollers 371 press the connecting plate 35 downward, so that the connecting plate 35 moves downward, driving the four connecting columns 33 to move downward, thereby driving the probe plate 32 to move downward, so that multiple elastic probes 31 can detect the circuit board body 100. After the detection is completed, if the circuit board body 100 is qualified, the linear mechanism 7 will not operate. If the circuit board body 100 is unqualified, the linear mechanism 7 will operate to push the upper conveying platform 5, so that the circuit board body 100 on the rotating body 2 can fall onto the lower conveying platform 6.

[0100] Then the driving mechanism 4 is run forward again to drive the rotating body 2 to rotate, so that the circuit board body 100 that has been inspected falls onto the corresponding transportation platform, and drives the next circuit board body 100 to rotate to a horizontal state. The equipment can classify and transport the circuit board bodies 100 that have been inspected. The staff only needs to load the circuit board bodies 100, which reduces the difficulty of the staff's work, prevents the phenomenon of manual material collection and mixing, and ensures the smooth progress of the production and inspection of the circuit board.

[0101] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.
