[0027] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0028] Embodiment: as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 indicated, the device for improving the contact rate of the anisotropic conductive sheet and the pin, including the mechanical arm 1 with X, Y direction movement, and the movement end of the mechanical arm 1 is provided with the positioning plate 2, the positioning plate 2 is equipped with the identification camera 3,

[0029] After the recognition camera 3 identifies the position of the alignment indentation on the blueing film, the robotic arm 1 drives the recognition camera 3 to move slightly in the X and Y directions to scan the position of the alignment indentation. The recognition camera 3 is used to preliminarily identify the position of the alignment indentation on the blueing film, and then the recognition camera scans the position of the alignment indentation on the blueing film in the X and Y directions, performing a four-square format scan by moving the front and back rows 40-60 microns left and right in the X and Y directions until the scanned alignment indentation is located in the center. At this time, the alignment indentation is located at the best position, thereby obtaining the accurate position of the alignment indentation. Then, it is conveniently and accurately docked with the conductive pin in the subsequent process, thereby ensuring a high contact rate after docking. In this way, the position of the material can be adjusted according to the position of the alignment indentation being located in the center, so that the conductive pins of the material can be accurately docked, thereby reducing the contact failure rate.

[0030] The robot arm 1 includes an X-axis electric slide 101 arranged in the X direction, a mounting bracket 102 is provided at the sliding end of the X-axis electric slide 101, and a Y-axis electric slide 103 arranged in the Y direction is provided on the mounting bracket. The positioning plate 2 is mounted on the sliding end of the Y-axis electric slide 103. This allows multiple free ends to move, making position adjustment convenient.

[0031] The X-axis electric slide 101 is equipped with an X-axis distance sensor for detecting the travel distance of the X-axis electric slide 101, and the Y-axis electric slide 103 is equipped with a Y-axis distance sensor for detecting the travel distance of the Y-axis electric slide. Both the X-axis distance sensor and the Y-axis distance sensor are photoelectric sensors. This facilitates accurate alignment of the camera's travel distance and facilitates scanning motion control.

[0032] The robotic arm 1 drives the recognition camera 3 to scan and move in the X and Y directions by 40-60 microns in the front and back rows and left and right, so as to perform fine movement scanning, thereby making the scanned position more accurate.

[0033] After scanning, the recognition camera 3 is positioned until the alignment mark scanned by the recognition camera 3 is centered. The alignment mark is then optimally positioned. The positioning plate 2 is also provided with a suction nozzle 4 for suctioning and transporting the material carrier. The positioning plate 2 is provided with a first linear electric guide rail 5 for moving the suction nozzle 4 up and down. This facilitates control of the suction nozzle 4's extension and retraction, and facilitates loading and position adjustment of the carrier.

[0034] There are two groups of positioning plates 2, and each positioning plate is provided with a recognition camera 3 and a suction nozzle 4.

[0035] The robotic arm 1 drives the material in the suction nozzle 4 to move 50 microns in the X and Y directions, and puts it into the carrier, so as to adjust the position of the carrier carrying the test piece and facilitate subsequent position docking.

[0036] Working principle: The position of the alignment indentation on the blue-stamped film is preliminarily identified by the identification camera 3, and then the identification camera performs position scanning on the alignment indentation on the blue-stamped film in the X and Y directions, and performs a 40-60 micron scanning movement in the front and back rows and left and right in the X and Y directions to perform a four-square format scan until the scanned alignment indentation is located in the center. At this time, the position of the alignment indentation is optimal, so as to obtain the accurate position of the alignment indentation, and then conveniently and accurately dock with the conductive pin in the subsequent process, thereby ensuring a high contact rate after docking. In this way, the position of the material can be adjusted according to the position of the alignment indentation in the center, so that the conductive pins of the material can be accurately docked, thereby reducing the poor contact rate.
