[0022] In this embodiment, the alignment base 5 can be moved by setting the second electric slide rail 3, and the alignment base 5 can transport the detection target. Then, the detection target is moved to a suitable position by the control module 8, the motion control module 801 and the vision processing module 802, and then the detection target is aligned to complete the detection.

[0023] In a further preferred embodiment of the present invention, a contact probe 102 is connected to the side of the testing machine 1, and a connecting frame 101 is fixedly connected to the outer side of the contact probe 102.

[0024] In this embodiment, the connecting frame 101 can move with the contact probe 102 to complete the contact between the contact probe 102 and the detection target, thereby completing the detection.

[0025] In a further preferred embodiment of the present invention, a first electric slide rail 203 is installed on the top of the second bracket 201 near the testing machine 1, and the first electric slide rail 203 is slidably connected to the connecting frame 101.

[0026] In this embodiment, the first electric slide rail 203 can drive the connecting frame 101 to move on it, completing the forward and backward movement of the connecting frame 101, thereby facilitating the movement of the connecting frame 101 with the contact probe 102 to contact the detection target for detection.

[0027] In a further preferred embodiment of the present invention, a third electric slide rail 401 is installed on the top of the movable base 4. The third electric slide rail 401 is slidably connected to the positioning base 5, and the third electric slide rail 401 is vertically distributed with the second electric slide rail 3 in the horizontal direction.

[0028] In this embodiment, the third electric slide rail 401 can move the alignment base 5 in another direction, which facilitates control of the distance between the detection target and the detection machine 1 and makes it convenient to adjust the position of the detection target.

[0029] In a further preferred embodiment of the present invention, four sets of limiting posts 7 are symmetrically distributed on both sides of the alignment base 5. The lower end of the limiting post 7 is fixedly connected to a limiting rod 701. An adjustment groove 501 is provided at the connection between the limiting rod 701 and the limiting post 7 and the alignment base 5.

[0030] In this embodiment, the four sets of limiting posts 7 can clamp the detection target placed on the alignment base 5, so as to facilitate close contact with the contact probe 102.

[0031] In a further preferred embodiment of the present invention, a motor 601 is connected to the bottom of the adjusting base 6, and the motor 601 is installed inside the positioning base 5.

[0032] In this embodiment, the motor 601 can drive the adjustment base 6 to rotate, so that the placed detection target can be rotated by the adjustment base 6 to adjust the angle, so that the detection target can be aligned with the contact probe 102.

[0033] In a further preferred embodiment of the present invention, an electric telescopic rod 702 is connected between the two sets of limiting rods 701. The electric telescopic rod 702 is distributed inside the adjusting groove 501 and is fixedly connected to the alignment base 5.

[0034] In this embodiment, the electric telescopic rod 702 can drive the limiting rod 701 to move, and then allow the limiting post 7 to approach and complete the clamping and fixing of the detection target, which facilitates subsequent detection.

[0035] In a further preferred embodiment of this utility model, two sets of lighting lamps 202 are distributed on both sides of the industrial camera 9, and the lighting lamps 202 are fixedly connected to the second bracket 201.

[0036] In this embodiment, the lighting lamp 202 can illuminate the space below, making it easier for the industrial camera 9 to identify the position of the target to be detected below.

[0037] In summary, by setting a movable contact probe 102 on the side of the inspection machine 1, which can be driven by the connecting frame 101, and then placing the target to be inspected on the alignment base 5, the industrial camera 9 monitors the target. The motion control module 801 controls the second electric slide rail 3 to move the movable base 4, and the alignment base 5 is also on the third electric slide rail 401. At the same time, the industrial camera 9 identifies and controls the motor 601 to rotate the adjusting base 6. When the adjusting base 6 rotates, the angle of the target to be inspected can be adjusted on the alignment base 5. Then, the electric telescopic rod 702 retracts and moves the limiting rod 701, so that the limiting post 7 clamps the side of the adjusted target to complete the fixation. After the fixation is completed, the connecting frame 101 moves on the first electric slide rail 203, causing the contact probe 102 to contact the target to complete the inspection. In this way, the alignment of the target to be inspected can be achieved through the first electric slide rail 203, the second electric slide rail 3, the third electric slide rail 401, and the adjusting base 6, which facilitates the inspection.
