Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 A PCB board testing gripper moving mechanism includes a mounting plate 1. A crossbar 11 is mounted on the top of the mounting plate 1. A slide groove 13 is provided at the top of the crossbar 11. A longitudinal moving component is mounted at the slide groove 13. A rotating component is mounted on the longitudinal moving component. An L-shaped support rod 7 is mounted on the rotating component. An adjusting component is mounted on the horizontal section of the L-shaped support rod 7. A first electric push rod 2 is mounted on the adjusting component. An electric gripper 3 (model PGI-140-80) is connected to the lower end of the first electric push rod 2. A camera 17 is connected to the lower end of the horizontal section of the L-shaped support rod 7. A control module 14 is mounted on the mounting plate 1. The control module 14 integrates control buttons and a display screen. The control module 14 is electrically connected to the camera 17. Fixing holes are provided at the four corners of the mounting plate 1. The mounting plate 1 can be fixed to the installation position using bolts through the fixing holes. The length of the horizontal section of the L-shaped support rod 7 is greater than the width of the mounting plate 1.

[0023] The longitudinal movement assembly includes a screw 12 rotatably mounted via a bearing, a moving block 10 screwed onto the screw 12, the moving block 10 being slidably engaged with a slide groove 13, and a first servo motor 4 mounted on one end of a crossbar 11, the output end of the first servo motor 4 extending into the slide groove 13 and connecting to one end of the screw 12.

[0024] The rotating assembly includes a U-shaped frame 9 fixed to the upper end of the moving block 10. A reducer 15 is installed on the inner side of the U-shaped frame 9. A rotating rod 18 is connected to the output end of the reducer 15. The upper end of the rotating rod 18 extends to the top of the U-shaped frame 9 and is connected to a turntable 8. A second servo motor 16 is connected to the input end of the reducer 15, and the second servo motor 16 is fixed to the outer wall of the reducer 15.

[0025] The rotating rod 18 is rotatably connected to the middle of the horizontal section of the U-shaped frame 9 through a bearing, which provides rotational support for the rotating rod 18 and prevents the rotating rod 18 from swaying.

[0026] Mounting plate 1 is fixed to the external mounting bracket between the feeding station and the inspection station. The electric gripper 3 is pushed down by the first electric push rod 2. The electric gripper 3 is clamped on the conveying station by the control button. The first electric push rod 2 is then retracted to move the electric gripper 3 and the PCB board up. The second servo motor 16 drives the reducer 15 to rotate, which in turn drives the rotating rod 18 and the turntable 8 to rotate, causing the L-shaped support rod 7 to rotate. This moves the electric gripper 3 and the PCB board above the inspection station. The first electric push rod 2 is then pushed down to move the electric gripper 3 and place the PCB board on the inspection station, thus completing one PCB board gripping operation. During the above operation, the image transmitted from the camera 17 to the display screen can be viewed in real time. The first servo motor 4 drives the screw 12 to rotate, which in turn drives the moving block 10 to move along the slide 13, facilitating the movement of the electric gripper 3 above the PCB board and assisting in the clamping operation.

[0027] Example 2 is an optimization based on Example 1. Specifically, the adjustment component includes a second electric push rod 6 fixed to the upper end of the horizontal section of the L-shaped support rod 7. One end of the second electric push rod 6 is connected to a sliding sleeve 5, which is slidably sleeved on the horizontal section of the L-shaped support rod 7. The first electric push rod 2 is connected to the bottom end of the sliding sleeve 5.

[0028] By controlling the extension and retraction of the second electric push rod 6, the sliding sleeve 5 can be driven to slide along the horizontal section of the L-shaped support rod 7, which facilitates further fine-tuning of the electric gripper 3 and improves the clamping accuracy.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
