Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor discrete devices, in particular to a detection device for semiconductor discrete device production. Background Technique

[0002] Semiconductor discrete devices are one of the bases of power electronic products and also one of the core devices constituting power electronic conversion devices. They are mainly used for rectification, voltage regulation, switching, mixing, etc. of power electronic equipment and are widely used in many national economic fields such as consumer electronics, computers and peripheral equipment, and network communication. Semiconductors are the core components of electronic products. When repairing circuit boards, fixed repair is required;

[0003] For example, patent number CN202322884613.3 discloses a fixing device for semiconductor discrete devices, including a fixing frame. Four groups of bases are vertically and downwardly fixedly connected to the bottom surface of the fixing frame. A workbench is horizontally and fixedly connected to the top surface of the fixing frame. Sliding grooves are horizontally opened on both sides of the top surface of the workbench. A moving plate is horizontally movably arranged on the top surface of each group of sliding grooves. An electric telescopic rod is horizontally and fixedly installed on the top of the moving plate. The vertically fixed connection of the mutually approaching ends of the two groups of electric telescopic rods is a clamping plate. Limiting grooves are horizontally opened at the top and bottom of the mutually approaching side surfaces of the two groups of clamping plates. An extrusion plate is horizontally movably arranged at the bottom of each group of clamping plate surfaces. A hydraulic pump is fixedly installed at the center position of the top surface of each group of clamping plates. When fixing the semiconductor discrete device in the utility model, first place the component into the center position of the top surface of the workbench, horizontally move each group of moving plates. Each group of sliders is vertically located inside the corresponding sliding grooves, thus playing a limiting role on the moving plates and preventing the moving plates from shifting when moving. Then, the two ends of the clamping plate can be driven to move horizontally through the electric telescopic rod, thus playing a clamping role on the semiconductor parts. Start each group of hydraulic pumps. Each group of extrusion plates can be driven to move up and down through the hydraulic pumps. The two ends of the semiconductor are squeezed and fixed through each group of extrusion plates. The material of each group of extrusion plates is rubber material, avoiding damage to the parts. At the same time, the motor can be used to drive the adjusting rotating threaded rod to rotate. The cooperation of the sliding rod and the moving sleeve can achieve the effect of moving the moving block back and forth. Finally, the staff can magnify the surface of the semiconductor through a magnifying glass, which is convenient for detecting the surface of the parts. However, during the use of the semiconductor discrete device detection device by the staff, since most semiconductor discrete device detection devices can only detect one semiconductor discrete device, if the number of semiconductor discrete devices is large, batch detection of semiconductor discrete devices cannot be carried out, and the work efficiency is low. Moreover, the fixing mechanism of the semiconductor discrete device cannot be flipped. When it is necessary to detect the back of the semiconductor discrete device, it is necessary to disassemble and reassemble the semiconductor discrete device again, which is rather troublesome;

[0004] Therefore, in the process of the above semiconductor discrete device detection device being used by staff, since most semiconductor discrete device detection devices can only detect one semiconductor discrete device, if the number of semiconductor discrete devices is large, batch detection of semiconductor discrete devices cannot be carried out, resulting in low work efficiency. Moreover, the fixing mechanism of the semiconductor discrete device cannot be flipped. When it is necessary to detect the back surface of the semiconductor discrete device, it is necessary to reinstall the semiconductor discrete device again, which is rather troublesome. A detection device for semiconductor discrete device production can be designed. By rotating the knob, the limit block slides inside the displacement groove, and then the limit block clamps semiconductor discrete devices of the same specification. After closing the device lid, during detection, the rotating positioning plate is driven by the rotating shaft rod to rotate inside the support frame, so as to facilitate the device to comprehensively detect the outer surface of the semiconductor discrete device and improve the detection efficiency.
