When equipment failure or excessive pressure occurs, it cannot perform emergency protection operations on the chip in a timely manner. Both the practicality and functionality need to be improved.

Once the force is excessive, the movable platform is retracted into the avoidance cavity to prevent the chip from being subjected to excessive squeezing force, thereby effectively protecting the chip.

[0008] Furthermore, the pressure detection mechanism includes a fixed seat, a piston rod is slidably connected to the upper port of the fixed seat, the internal cavity of the fixed seat is filled with hydraulic oil, a mounting hole is provided on the upper surface of the fixed seat, and a pressure sensor is fixedly installed inside the mounting hole, and the detection end of the pressure sensor is placed inside the hydraulic oil.

[0009] By adopting the above technical solution, the external force can be converted into the oil pressure of the hydraulic oil, and then the pressure sensor is used for detection operation.

[0010] Furthermore, a cylinder is fixedly installed on the side surface of the supporting side plate, and a movable support block is fixedly connected to the telescopic end of the cylinder. Two limit bars are fixedly connected to the upper surface of the supporting bottom plate, and a slide groove is provided on the lower end surface of the movable support block. The limit bar is snapped into the slide groove, and the upper end of the movable support block rests on the lower surface of the fixed seat.

[0011] By adopting the above technical solution, the cylinder can be used to drive the movable support block to move, thereby ensuring that emergency protection can be achieved.

[0012] Furthermore, a pressure switch and a control relay are fixedly installed on the side surface of the supporting side plate, the pressure sensor is electrically connected to the pressure switch, the pressure switch is electrically connected to the control end of the control relay, and the control relay is electrically connected to the solenoid valve of the external control cylinder.

[0013] By adopting the above technical solution, the pressure switch can be used to determine whether the pressure exceeds the range, and the control relay can be used to realize the control operation of the cylinder.

[0014] Furthermore, a buzzer is fixedly mounted on the side surface of the supporting side plate, and the buzzer is electrically connected to the pressure switch.

[0015] By adopting the above technical solution, the working circuit of the buzzer can be closed when the squeezing force is excessive, thereby realizing the alarm operation.

[0016] Furthermore, a semicircular exhaust hole is provided on each of the four side surfaces of the movable platform.

[0017] By adopting the above technical solution, it is ensured that the movable platform can be stably and quickly retracted into the avoidance cavity.

[0018] In summary, the beneficial technical effects of the utility model are:

[0019] The utility model can utilize the pressure detection mechanism to detect the force applied to the movable platform in real time, and transmit the detected force to the pressure switch. Once the set pressure value is exceeded, the pressure switch transmits an electrical signal to the control relay, and the control relay closes the solenoid valve of the control cylinder, causing the cylinder to contract, thereby moving the movable support block out from directly under the pressure detection mechanism, so that the telescopic rod and the support spring provide support for the pressure detection mechanism and the movable platform. At this time, the external extrusion structure can press the movable platform into the avoidance cavity, thereby preventing the semi-finished product above the movable platform from being subjected to excessive extrusion force, and performing emergency protection operations on the semi-finished product. The entire mechanism can monitor the extrusion force in real time and perform emergency protection operations when the pressure is excessive, thereby effectively improving practicality and functionality.

The limit strip 11 is buckled in the slide groove. The upper end of the movable support block 10 is against the lower surface of the fixed seat 14. A pressure switch 5 and a control relay 7 are fixedly installed on the side surface of the supporting side plate 2. The pressure sensor 15 is electrically connected to the pressure switch 5, and the pressure switch 5 is electrically connected to the control end of the control relay 7. The control relay 7 is electrically connected to the solenoid valve of the external control cylinder 8. The pressure detection mechanism 9 can be used to detect the force applied to the movable platform 4 in real time, and the detected force is transmitted to the pressure switch 5. Once the set pressure value is exceeded, the pressure switch 5 An electrical signal is transmitted to the control relay 7, and the control relay 7 closes the solenoid valve of the control cylinder 8, causing the cylinder 8 to contract, thereby moving the movable support block 10 out from directly under the pressure detection mechanism 9, so that the telescopic rod 12 and the support spring 13 provide support for the pressure detection mechanism 9 and the movable platform 4.

[0025] Reference Figure 1A buzzer 6 is fixedly installed on the side surface of the supporting side plate 2, and the buzzer 6 is electrically connected to the pressure switch 5. A semicircular exhaust hole is arranged on the four side surfaces of the movable platform 4. When the pressure is excessive, the pressure switch 5 closes the working circuit of the buzzer 6, and the buzzer 6 emits an alarm sound to remind the staff that the equipment has failed and needs to be adjusted.

[0026] Working principle: When in use, first install the mechanism at the designated position, then place the semi-finished product to be flattened on the movable table 4, and then use the external extrusion structure to flatten the semi-finished product. During the flattening process, the force applied to the semi-finished product can be effectively transmitted to one end of the piston rod 16, and the other end of the piston rod 16 squeezes the hydraulic oil inside the fixed seat 14 to increase the oil pressure of the hydraulic oil. Since the detection end of the pressure sensor 15 is placed in the hydraulic oil, the pressure of the hydraulic oil can be detected in real time, and then the force applied to the semi-finished product can be detected, and then the force data is transmitted to the pressure switch 5. Once the force exceeds the set value, the pressure switch 5 is The control relay 7 controls the transmission of an electrical signal, and the control relay 7 closes the solenoid valve of the control cylinder 8, causing the cylinder 8 to contract, thereby moving the movable support block 10 out from directly below the pressure detection mechanism 9, so that the telescopic rod 12 and the support spring 13 provide support for the pressure detection mechanism 9 and the movable platform 4. At this time, the supporting force of the movable platform 4 is insufficient. Under the extrusion of the external extrusion structure, the movable platform 4 retracts into the avoidance cavity 19, so as to prevent the semi-finished product from being subjected to excessive force, and can effectively realize emergency protection operation. When the external extrusion structure is reset, the support spring 13 resets the movable platform 4, and then extends the cylinder 8, so that the movable support block 10 is reset and normal flattening operation can be performed.

Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
