[0026] Specifically, the rotating frame structure includes: a rotating support frame 5, two bearings 6, a rotating shaft 7, and a driven gear 8; the rotating support frame 5 is installed on the upper wall surface of the bottom plate 1, the two bearings 6 are respectively installed inside the rotating support frame 5, the rotating shaft 7 is installed inside the two bearings 6, the driven gear 8 is installed on the lower wall surface of the rotating shaft 7, and the driven gear 8 is a bevel gear. The rotating frame structure can transmit the power torque of the power structure to the rotating disc structure, enabling the rotating disc structure to rotate stably. At the same time, the rotating frame structure can change the torque of the power structure from the horizontal direction to the vertical direction, thus facilitating the rotation of the rotating disc structure in the horizontal direction and facilitating the visual inspection structure to detect the PIN pins.

[0027] Specifically, the rotating disc structure includes: a rotating support base 9 and a rotating disc 10; the rotating support base 9 is installed on the upper wall surface of the rotating shaft 7, the rotating disc 10 is installed on the upper wall surface of the rotating support base 9, and several clamping structures include: a magnetic base 11, a clamping fixture 12, and a PIN pin loading seat 13; the magnetic base 11 is installed on the upper wall surface of the rotating disc 10, the clamping fixture 12 is magnetically adsorbed on the upper wall surface of the magnetic base 11 through magnetic force, the PIN pin loading seat 13 is movably installed inside the clamping fixture 12, and multiple clamping structures are installed above the rotating disc structure, which can realize a multi-station detection mode. It can enable the clamping structure to perform visual inspection while also realizing the functions of loading and unloading of the clamping structure, effectively improving the detection efficiency. By setting the clamping structure, the PIN pin loading seat 13 can be quickly replaced, thus facilitating the detection of PIN pins of different specifications and having a wide range of applications.

[0028] Specifically, the power structure includes: a power motor 14 and a driving gear 15; the power motor 14 is installed on the upper wall surface of the bottom plate 1, the driving gear 15 is installed on the driving end of the power motor 14, the driving gear 15 and the driven gear 8 are meshed with each other, and the driving gear 15 is a bevel gear. The power structure can provide energy for the rotation of the rotating disc structure and, under the control of a matching computer, enable the rotating disc structure and the visual inspection structure to work together.

[0029] Specifically, positioning small holes 111 are formed on the upper wall surface of the magnetic base 11, and a plurality of positioning protrusions 121 that are inserted and matched with the positioning small holes 111 are fixedly provided on the lower wall surface of the clamping fixture 12. The positioning small holes 111 include a first positioning hole 112 and a plurality of second positioning holes 113. The first positioning hole 112 is provided at the middle position of the upper wall surface of the magnetic base 11, and the plurality of second positioning holes 113 are respectively provided at the four corner positions of the upper wall surface of the magnetic base 11.

[0030] Such as Figure 4As shown, the clamping fixture 12 is positioned through the first positioning hole 112, and the rotation of the clamping fixture 12 is restricted through the second positioning hole 113. While the clamping fixture 12 is stably installed on the magnetic base 11, the positioning of the clamping fixture 12 is made more accurate. When the clamping fixture 12 needs to be replaced, only the old clamping fixture 12 needs to be removed, and then the new clamping fixture 12 is inserted into the magnetic base 11.

[0032] As Figure 4 shown, during the use process, by screwing the screwing shaft 124, the clamping plate 125 is retracted outward, so that the PIN needle loading seat 13 can be loosened for movement. After the PIN needle is loaded into the PIN needle loading seat 13, by screwing the screwing shaft 124, the clamping plate 125 is pushed forward, so that the PIN needle loading seat 13 can be stably clamped, thus facilitating the replacement of PIN needle loading seats 13 of different specifications.

[0033] Working principle: When using the present utility model, first connect an external AC power supply to the present utility model to provide energy for the electrical appliances in the present utility model. Then, the operator connects a computer to the present utility model and connects the power motor 14 and the vision module 4 to the computer respectively, so that the power motor 14 and the vision module 4 can be programmed and controlled through the computer. The operator first takes the clamping fixture 12 from the magnetic base 11, installs the PIN needle loading seat 13 loaded with PIN needles inside the clamping fixture 12, and installs the clamping fixture 12 on the upper wall surface of the magnetic base 11 by magnetic force. At this time, start the present utility model. When the PIN needle loading seat 13 loaded with PIN needles passes below the vision module 4, the power motor 14 stops working and the vision module 4 starts to work, scanning the PIN needles inside the PIN needle loading seat 13 to form a three-dimensional digital file stored in the computer. The computer calculates the length of the PIN needles through software to determine whether the length of the PIN needles is qualified. When it is found that the length of a PIN needle is unqualified, the computer will give an unqualified prompt to remind the operator to remove the unqualified PIN needles. Then, the power motor 14 continues to drive the driving gear 15 to rotate, driving the driven gear 8 to rotate through meshing, that is, driving the rotating shaft 7 to rotate. The rotating shaft 7 can drive the rotating support seat 9 and the rotating disc 10 to rotate, so that the magnetic base 11 and the clamping fixture 12 pass below the vision module 4. When the PIN needle loading seat 13 is below the vision module 4, the power motor 14 stops working and the vision module 4 starts to perform three-dimensional digital scanning on the next group of PIN needles. The vision module 4 is a general technology in the prior art and will not be elaborated here.
