DETAILED DESCRIPTION
[0019] The present invention can be more easily understood by referring to the following detailed description of the preferred embodiments of the present invention and the included Examples. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which the present invention belongs. In the event of any conflict, the definitions in this specification shall prevail.
[0020] Example 1:
[0021] Provides such Figure 1 The illustrated lead frame inspection mechanism comprises a testing platform 1, a flattening device 2, a handling device 3, and a suction cup assembly 4. The flattening device 2 is positioned at one end of the testing platform 1, the handling device 3 is positioned at the other end, and the suction cup assembly 4 is mounted on the handling device 3. The flattening device 2 is used to flatten the lead frame, while the handling device 3 is used to move the suction cup assembly 4, which is used to absorb the lead frame. The handling device 3 is a two-degree-of-freedom robotic arm.
[0022] The flattening device 2 includes a fixing frame 21, a cylinder 22, and a pressing plate 23. The cylinder 22 is fixedly mounted on the fixing frame 21, and the pressing plate 23 is connected to the cylinder 22. The cylinder 22 is vertically arranged, and the pressing plate 23 is arranged at the bottom of the cylinder 22.
[0023] The suction cup assembly 4 includes a fixing plate 41 and suction cups 42 . Four suction cups 42 are provided and are evenly distributed in a matrix on the fixing plate 41 .
[0024] The detection platform 1 further comprises a conductor rack transfer platform 5, which is arranged on one side of the detection platform 1. A distance sensor 6 is arranged at one end of the conductor rack transfer platform 5.

[0026] Working principle: The handling device 3 drives the suction cup assembly 4 to move the wire rack from the wire rack transfer table 5 to the detection platform 1. After the suction cup 42 absorbs the wire rack, the distance sensor 6 detects the thickness of the absorbed wire rack. If the thickness of the wire rack is greater than the thickness of one wire rack, it is determined that multiple wire racks are hung together, and the machine is shut down and an alarm is issued, waiting for staff to handle it.
[0027] After the lead frame is placed on the testing platform 1, the cylinder 22 drives the pressing plate 23 downward, which flattens the lead frame and eliminates the effects of lead frame deformation. The suction cup 42 then picks up the lead frame and moves it to the coil fixture plate 8 on the conveyor 7.
