An opening 21 cooperating with the electric push rod 2 is provided at the top, which is used for the telescopic end of the electric push rod 2 to be telescopically inserted. The lower end of the connecting rod 32 is fixedly connected to the downward pressure plate 22, and a sealing structure is provided at the sliding position of the connecting rod 32 and the oil storage cylinder 31. The sealing structure is a sealing member that can achieve a sealing effect, which will not be elaborated here. Filling liquid is added to the inside of the oil storage cylinder 31, and the filling piston 34 is slidably connected to the oil storage cylinder 31. The filling piston 34 is adapted to the oil storage cylinder 31, and the lower end of the delivery pipe 33 is connected to the non-rigid pressure part 3. The non-rigid pressure part 3 is provided with a cavity inside, and the non-rigid pressure part 3 is made of rubber material.

[0025] Embodiment 2: Based on Embodiment 1, the adjusting component includes an adjusting screw 4 threadedly installed on one side of the downward pressure plate 22, an adjusting knob 42 is installed at the upper end of the adjusting screw 4, and a pressure sensor 41 is installed at the lower end of the adjusting screw 4. By adjusting the height position of the pressure sensor 41, the extrusion force applied to the packaging cover plate can be controlled.

[0026] When used specifically, the utility model is a clamping component for chip packaging. The design is installed on the packaging machine through the mounting seat 1. After the dispensing and capping of the special-shaped chip are completed, the electric push rod 2 is controlled through the externally connected control end. When the electric push rod 2 is extended, the connecting rod 32 and the filling piston 34 are driven to move downward. Through the downward movement of the filling piston 34, the liquid in the filling and oil storage cylinder 31 can be injected into the non-rigid pressure part 3. After the liquid is injected into the non-rigid pressure part 3, the non-rigid pressure part 3 will expand and expand. The expanded non-rigid pressure part 3 will contact the packaging cover plate.

At the same time, the non-rigid pressure part 3 The contact extrusion mode will not cause crushing injuries. When the pressure sensor 41 contacts the place where the special-shaped chip is placed, a pressure signal will be generated and transmitted to the control end.
