Description

Technical Field

[0001] The utility model relates to the technical field of diode production devices, in particular to a surface grinding device for diode processing. Background Technique

[0002] A diode is a semiconductor device made based on the special properties of a PN junction. The PN junction is formed by the combination of an n-type semiconductor and a p-type semiconductor. There are two states on the PN junction: forward bias and reverse bias. In the forward bias state, current can flow smoothly through the PN junction, and the diode has good conductivity, which is called the forward conduction state. In the reverse bias state, a reverse electric field is formed on the PN junction, hindering the passage of current, and the diode is in the cut-off state. Due to the characteristics of these two states of the diode, the application range of the diode is wide.

[0003] The manufacturing process of diodes mainly includes chip crystal growth, cutting and grinding, diffusion and alloying, and metallization and packaging. At present, when diodes are processed and ground, most of the time, workers hold the diodes and manually grind them on the grinding belt. The grinding efficiency is not good, and because the diodes are small in size, and when facing batch grinding, after workers work for a long time, it is easy to accidentally touch the grinding belt due to fatigue, thus causing damage to the fingers. In view of the above problems, the inventor proposes a surface grinding device for diode processing to solve the above problems. Content of the Utility Model

[0004] In order to solve the problems of poor grinding efficiency and low safety when diodes are currently processed and ground; the purpose of the utility model is to provide a surface grinding device for diode processing.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: a surface grinding device for diode processing, including a transportation cavity, the transportation cavity includes a conveyor belt, the outer side wall of the conveyor belt is fixedly connected with a diode placement seat, one side of the transportation cavity is provided with a supporting plate, an electric cylinder is placed on the top surface of the supporting plate, the output shaft end of the electric cylinder is fixedly connected with a movable seat, the top surface of the movable seat is fixedly connected with a vertical frame, the inner wall of the vertical frame is rotatably connected with a first roller shaft and a second roller shaft, and a grinding belt is sleeved on the side walls of the first roller shaft and the second roller shaft.

[0006] Preferably, a diode body is placed in the placement opening of the diode placement seat. There are several diode placement seats, and several of these diode placement seats are evenly distributed on the conveyor belt. As shown in the figure, the conveyor belt rotates from left to right. Therefore, the left side of the grinding belt is the loading station, and the right side of the grinding belt is the unloading station. Workers place the diode body in the diode placement seat at the loading station. The surface of the diode body can be polished by the grinding belt. After polishing, the diode body will move to the unloading station. Workers take out the polished diode body from the diode placement seat at the unloading station to place a new diode body to be polished again. In actual use, when placing diode bodies of different shapes, the diode placement seat needs to be matched with the diode body.

[0007] Preferably, legs are fixedly connected to the four corners of the bottom surface of the supporting plate. A guiding groove is penetrated through the side surface of the supporting plate. Slide rails are fixedly connected to both sides of the bottom surface of the movable seat. The slide rails correspond to the guiding groove and are slidably connected. A guiding rod is fixedly connected to the side wall of the movable seat. Guiding cylinders are fixedly connected to both sides of the top surface of the supporting plate. The guiding rod corresponds to the mouth of the guiding cylinder and is slidably connected. The legs are used to support the supporting plate. Start the electric cylinder. Under the action of the output shaft of the electric cylinder, the movable seat can be moved, and thus the position of the grinding belt can be adjusted so that the grinding belt can contact the surface of the diode body to polish the diode body. And through the mutual cooperation of the slide rail and the guiding groove, and with the cooperation of the guiding rod and the guiding cylinder, the movable seat can move more smoothly. A fixing seat is arranged on the side wall of the electric cylinder. The bottom surface of the fixing seat is fixedly connected to the top surface of the supporting plate. The electric cylinder is installed through the fixing seat.

[0008] Preferably, a motor is inserted through the side wall of the vertical frame. A first pulley is fixedly connected to the output shaft end of the motor. A synchronous belt is arranged on the side wall of the first pulley. A second pulley is arranged at one end of the synchronous belt away from the first pulley. A horizontal shaft is inserted and fixedly connected to the middle of the side wall of the second pulley. The horizontal shaft is fixedly connected to the shaft end of the first roller shaft. The shaft ends of the first roller shaft and the second roller shaft both extend into the vertical frame, and the shaft ends of the first roller shaft and the second roller shaft are rotatably connected to the vertical frame. Start the motor. The first pulley rotates under the action of the output shaft of the motor. The second pulley can be rotated through the synchronous belt, and then the first roller shaft can drive the grinding belt to move to polish the diode body.

The grinding efficiency is high. After grinding, the staff can take out the ground diode body from the diode placement seat at the blanking station to place a new diode body to be ground again.

[0011] 2. In the utility model, the grinding belt can be adjusted in position to improve applicability. The electric cylinder can be used to move the movable seat, and then the position of the grinding belt can be adjusted so that the grinding belt can contact the surface of the diode body for grinding operation on the diode body.
