[0027] Refer to Figures 1 to 4 , the present application provides an LED driver chip detection device, including a workbench 1, a transfer assembly 2, a detection assembly 3, and a flipping assembly 4.

[0028] Through the stable support of the workbench 1 and the efficient transmission of the transmission component 2, the smooth conveyance of the chip tray is achieved, enabling the chip tray to accurately reach below the detection component 3, thereby ensuring the accuracy and stability of the detection, and the chip tray is flipped by the flipping component 4.

[0029] The transmission component 2 is fixed on the workbench 1, and the transmission component 2 is used to transmit the chip tray.

[0030] Through the continuous conveyance and precise positioning of the transmission component 2, the automated transmission of the chip tray from the starting position to the detection position is realized, reducing manual intervention and improving the overall detection efficiency and automation level.

[0031] Then the detection component 3 is erected directly above the transmission component 2 for detecting the chip tray transmitted by the transmission component 2.

[0032] Through the high-precision vision recognition and image processing technology of the detection component 3, the comprehensive detection of the appearance and electrical performance of the LED driver chips in the chip tray transmitted by the transmission component 2 is realized, ensuring that the quality of each LED driver chip meets the required standards.

[0033] Then the flipping component 4 is arranged on the workbench 1, and the flipping component 4 is arranged on both sides of the transmission component 2 for flipping the chip tray transmitted by the transmission component 2.

[0034] Through the mechanical structure and control system of the flipping component 4, the automatic flipping of the chip tray transmitted by the transmission component 2 is realized, enabling the detection component 3 to comprehensively detect different angles of the chip, avoiding errors and low efficiency caused by manual flipping.

[0035] In this embodiment, when the chip tray is placed on the workbench 1, the transmission component 2 conveys the chip tray along the transmission path to below the detection component 3, and the detection component 3 detects the appearance and electrical performance of the chip tray transmitted by the transmission component 2; after the detection is completed, the flipping component 4 performs a flipping operation on both sides of the transmission component 2 on the chip tray to ensure that all sides of all chips can be detected. The entire process is coordinated by the transmission component 2, the detection component 3, and the flipping component 4 to realize the automatic flipping of the chip tray, eliminating the step of manually flipping the chip tray, improving the detection efficiency, reducing the participation of manual operations, and improving the problem of poor detection accuracy and low efficiency when it is necessary to manually flip the chip tray for overall inspection.

[0046] Through the combination of the transverse transmission member 32 and the longitudinal transmission member 33, the two-way movement of the photographing member 34 above the workbench 1 is realized, so that each chip in the chip tray can be comprehensively detected. The high-resolution image acquisition function of the photographing member 34 ensures the accurate detection of the appearance and electrical performance of the chip, guaranteeing the accuracy of the detection results. In this application, the transverse transmission member 32 and the longitudinal transmission member 33 can be any kind of linear module, and preferably a servo motor linear module in this application.

[0047] A safety box 12 is provided at one end of the workbench 1 away from the bottom. A transfer port 121 is opened on the safety box 12, and the transfer port 121 is used to place the chip tray.
