Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, the embodiment of the utility model provides an intelligent pressing device, including a driving assembly 20, the driving assembly 20 includes a bracket 21, a cylinder 22, a pressing plate 23, an electric speed regulating valve 24, an air outlet pipe 25, an air inlet pipe 26, an electronic pressure regulating valve 27, an air pressure sensor 28 and a PLC controller 29;

[0028] The cylinder 22 is installed on the front surface of the bracket 21, and the piston rod of the cylinder 22 is detachably fixedly connected to the pressure plate 23. A pressure sensor is installed at the bottom of the pressure plate 23. The air outlet pipe 25 and the air inlet pipe 26 are connected to one side of the cylinder 22. Two electric speed regulating valves 24 are respectively installed on the air outlet pipe 25 and the air inlet pipe 26. The electronic pressure regulating valve 27 and the air pressure sensor 28 are installed on the air inlet pipe 26. The signal output ends of the pressure sensor and the air pressure sensor 28 are connected to the signal input ends of the PLC controller 29. The electrical output end of the PLC controller 29 is electrically connected to the electrical input ends of the electric speed regulating valve 24 and the electronic pressure regulating valve 27. The electric speed regulating valve 24 is used to adjust the intake speed. The pressure sensor at the bottom of the pressure plate 23 is squeezed by the pressing piece 19 during the movement of the pressing plate 23 and detects the pressure between the pressing piece 19 and the pressure plate 23, so as to facilitate the staff to observe the pressure value feedback.

[0029] In this embodiment, specifically: a main body assembly 10 is disposed at the bottom of the driving assembly 20, and the main body assembly 10 includes a base 11, a touch screen 12, a pressure gauge 13, an emergency stop switch 14, a start button 15, a barometer 16, a slide rail 17, a carrier 18, a pressing piece 19 and an in-place sensor 110;

[0030] The touch screen 12 is installed on the front surface of the base 11, and the touch screen 12 facilitates the staff to operate the pressing equipment.

[0031] In this embodiment, specifically: the pressure gauge 13 and the air pressure gauge 16 are installed on the front surface of the base 11, and the pressure gauge 13 and the air pressure gauge 16 are used to display the pressure value of the pressing plate 23 and the air pressure value of the cylinder 22 respectively.

[0032] In this embodiment, specifically: the emergency stop switch 14 is installed on the front surface of the base 11, and the two start buttons 15 are symmetrically installed on the front surface of the base 11. The emergency stop switch 14 is used to operate the pressing equipment to stop suddenly. A protective cover is provided on the outside of the emergency stop switch 14 to prevent the staff from accidentally touching the emergency stop switch 14. When the pressing equipment is pressing, the staff is required to operate the start button 15 with both hands at the same time, so as to ensure that the staff's hands are away from the carrier 18 to avoid safety accidents.

[0033] In this embodiment, specifically: the slide rail 17 is installed on the upper surface of the base 11 , and the arrangement of the slide rail 17 enables the carrier 18 to move forward and backward, so that the staff can easily load and unload the pressing piece 19 .

[0037] When the utility model is in operation: a pressing part 19 is placed on a carrier 18, pressing pressure is set through the touch screen 12, the air pressure value of the cylinder 22 under the pressure is calculated through the PLC controller 29, the carrier 18 is pushed to move until the in-place sensor 110 detects that the pressing part 19 is in place, and the start button 15 is operated with both hands to start pressing. During the pressing process, the air pressure sensor 28 detects the air intake pressure, and the pressure is adjusted through the electronic pressure regulating valve 27 until the air pressure value of the cylinder 22 reaches the specified air pressure value. The staff can observe whether the actual air pressure and pressure value deviate from the preset value through the pressure gauge 13 and the barometer 16, judge whether there is a fault in the equipment, and use the air pressure of the cylinder 22 to control the output pressure of the cylinder 22, so as to ensure that the product can complete the pressing assembly smoothly, avoid damage to the product during the pressing process, and improve the pressing effect of the product.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
