The upper and lower parts of the two conveyor belts 12 are respectively provided with a leveling upper plate mechanism and a leveling lower plate mechanism. The leveling upper plate mechanism includes four guide rods 23, an upper movable plate 21 slidably mounted in the middle of the four guide rods 23, a lower fixed plate 22 fixedly mounted on the lower part of the guide rods 23 by screws, and a motor fixed plate 24 fixedly mounted on the upper part of the guide rods 23. The leveling upper plate 3 is mounted on the lower part of the upper movable plate 21, and a press servo motor 25 is mounted on the motor fixed plate 24. The output end of the press servo motor 25 is connected to a screw rod 26, which passes through the upper movable plate 21. The leveling upper plate 3 is located above the thick silicone plate 13 between the two transport belts 12; the leveling lower plate mechanism includes a leveling lower plate 4 mounted on the upper part of the lower fixed plate 22 by screws, and the lower fixed plate 22 is located below the thick silicone plate 13 between the two transport belts 12.

[0025] The belt conveyor frame is equipped with a height adjustment mechanism, which includes a conveyor belt lifting cylinder 41 mounted below the lower fixed plate 22, a lifting plate 42 mounted at the end of the piston rod of the conveyor belt lifting cylinder 41, and lifting rods 43 mounted at the four corners of the lifting plate 42 and slidably passing through the lower fixed plate 22. The belt conveyor frame is mounted above the lifting rods 43. The leveling lower plate 4 is fixed above the lower fixed plate 22 and located below the thick silicone plate 13 between the two conveyor belts 12. The belt conveyor frame includes a left frame 14, a right frame 15, a long drive shaft connecting the left and right frames 14, 15, and a left belt driving pulley, a left belt driven pulley, a right belt driving pulley, and a right belt driven pulley mounted on the left and right frames 14, 15, respectively. The long drive shaft is connected to the output end of the belt conveyor motor 11, and the left and right belt driving pulleys are mounted at each end of the long drive shaft 16. A cleaning brush 9 is mounted on the outside of the long drive shaft.

[0026] In this embodiment, the upper movable plate 21 is equipped with four adjustment screws 5 for adjusting the parallelism of the leveling platform. The adjustment screws 5 extend through the upper movable plate 21 and connect to the upper leveling plate 3. The balance of the upper leveling plate 3 is adjusted by twisting the adjustment screws 5. Loosening or tightening the adjustment screws lowers or raises the upper leveling plate 3, completing the overall balance of the upper leveling plate 3. A thick silicone plate is installed on one side of the upper movable plate 21 to reach the limit cylinder 6. Leveling height pads 7 are located on both the front and rear sides of the upper movable plate 21. A sensor bracket 81 is mounted on the lower fixed plate 22. This bracket houses a press plate position sensor 8, which detects the current position of the press plate formed by the upper leveling plate 3 and the upper movable plate 21. Displacement sensors are located at the four corners of the upper leveling plate 3 and the lower leveling plate 4 to detect whether there is product or other impurities remaining on the plate surfaces. A belt conveyor frame is mounted on the lower fixed plate 22 and is equipped with a cleaning brush 9.

[0027] The working principle of the end plate flat leveling mechanism of the present invention is as follows: in the previous process, the thick silicone plate 13 presses the chip capacitor into the plate hole through the needle bed. It is automatically transported to the leveling platform position by the belt conveyor motor 11, and the thick silicone plate reaches the limit cylinder 6. During the process, the belt conveyor motor 11 drives the cleaning brush 9 to move and clean the products and foreign matter remaining on the plate surface. After reaching the position, the conveyor belt lifting cylinder 41 descends to place the thick silicone plate 13 on the leveling lower plate 4. The press servo motor 25 drives the leveling mechanism to lower the leveling upper plate 3 to the surface of the thick silicone plate 13 according to the operating speed, distance and other parameters set by the system. The displacement detection sensors at the four corners of the leveling platform detect whether there are products or other impurities remaining on the plate surface. When a problem occurs, an alarm is triggered in time for manual processing. After inspection, the press servo motor 25 precisely descends the set distance to the leveling pad 7. The protruding portion of the chip capacitor is pressed back into the hole in the thick silicone plate 13 via the leveling platform, ensuring a consistent protrusion. Finally, the leveling mechanism ascends back to the set origin, completing the chip capacitor leveling process. If the parallelism between the upper and lower leveling plates 3 and 4 is abnormal, the leveling platform parallelism adjustment screws 5 can be used to adjust the alignment. Once leveling is complete, the plates are transported to the slurry dipping process via the belt conveyor motor 11.
