Description

Technical Field

[0001] This utility model relates to the field of robotic arms, and more particularly to a flying probe testing robotic arm. Background Technology

[0002] After the circuit board is completed, it is necessary to check for any problems, such as broken lines (open circuit), short circuits in places that should not be connected, or incorrect resistor and capacitor values.

[0003] The traditional method is to use bed of needles testing (make a mold covered with probes, press it onto the board and test in batches), but this method is not flexible enough.

[0004] Another method is to use flying probe testing, which is more flexible—it does not use a mold, but instead sends two or more mechanical probes, like a woodpecker's beak, to move "tap tap tap" across the board, poking each test point and measuring data as it goes.

[0005] Existing flying probe testing mechanisms mostly drive the flying probe to move by setting up a three-axis motion mechanism of X, Y and Z axes. Although this structure can complete the test, it has the problems of complex structure and high cost, and needs to be improved. Utility Model Content

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figure 1-3 As shown, a flying probe testing robot includes a support column 16, a support cross plate 15 at the top of the support column 16, the right end of the support cross plate 15 being rotatably connected to the top of the support column 16, and a flying probe testing mechanism mounted on the left end of the support cross plate 15. A base 17 is provided at the bottom of the support column 16, and the bottom end of the support column 16 is fixedly connected to the base 17. Multiple fixing screws 18 are threadedly connected to the edge of the base 17.

[0024] In use, the fixing screw 18 is connected to the ground, thereby fixing the base 17 on the ground and thus fixing the position of the device.

[0025] Example 2

[0026] like Figure 1-3 As shown, while other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the flying probe testing mechanism includes an electric telescopic rod 14, which is fixedly connected to the left end of the supporting horizontal plate 15. The telescopic end 13 of the electric telescopic rod 14 faces downward and is fixedly connected to the top plate 1. A small motor 12 is provided below the top plate 1 and is fixedly connected to the top plate 1. The power telescopic end of the small motor 12 is fixedly connected to the upper end of the drive rod 11. A guide plate 3 is sleeved on the drive rod 11 and is threadedly connected to the guide plate 3. Guide rods 2 are provided through the left and right sides of the guide plate 3. The upper end of the guide rod 2 is fixedly connected to the top plate 1, and the lower end of the guide rod 2 is fixedly connected to the bottom plate 7. The bottom plate 7 is located below the guide plate 3. A cone 4 is fixedly provided at the bottom of the guide plate 3. The cone 4 is sleeved on the drive rod 11 and is threadedly connected to the drive rod 11. The cone 4 is used to drive the flying probe testing assembly to move.

[0027] The flying probe testing assembly includes a through hole 5. A through hole 5 is provided in the center of a base plate 7. A slide rod 9 is horizontally arranged through the left side of the base plate 7. The slide rod 9 slides with the base plate 7. A buffer spring 10 is sleeved on the slide rod 9. One end of the buffer spring 10 is fixed to the base plate 7, and the other end of the buffer spring 10 is fixed to the slide rod 9. A probe 8 is fixed at the bottom left end of the slide rod 9, and a ball bearing 6 is fixed at the right end of the slide rod 9.

[0028] In use, place a workbench under probe 8, then place the circuit board to be tested on the workbench. Then rotate the support plate 15, which drives the slide bar 9 to rotate synchronously, so that the slide bar 9 and the test point on the circuit board are in the same plane. Then start the small motor 12, which drives the drive rod 11 to rotate. The drive rod 11 drives the guide plate 3 and the cone 4 to move down, so that the cone 4 pushes the slide bar 9 to move outward. The slide bar 9 drives the probe 8 until the probe 8 moves directly above the test point on the circuit board. Then turn off the motor 11, and then start the electric telescopic rod 14, which drives the probe 8 to move up and down, so that the probe 8 can test the point on the circuit board.
