Description

Technical Field

[0002] Mylar film (PET polyester film) is a film produced by heating dimethyl terephthalate and ethylene glycol under the assistance of a relevant catalyst, through transesterification and vacuum polycondensation, followed by biaxial stretching. Mylar film exhibits dimensional stability, flatness, and excellent tear strength. It is heat and cold resistant, moisture and water resistant, chemically resistant, and possesses superior insulation properties, along with excellent electrical, mechanical, heat, and chemical resistance. Mylar film can be used as insulation material for motors, capacitors, coils, and cables, and can also be combined with barley paper to create composite insulation materials.

[0050] The processing procedure of the Mylar sheet is as follows Figure 5As shown, when the Mylar sheet is processed by the device, first, the controller is used to start each unit and adjust the movement frequency of each unit. After adjustment, the servo motor and die cutting machine 1 are started. The servo motor rotates and winds the die cutting waste of the Mylar sheet, providing a left moving force for the Mylar sheet. During the movement of the Mylar sheet, the die cutting machine 1 continuously presses to die cut the Mylar sheet. When the die cut Mylar sheet coil 4 moves to the separation roller 7, under the separation effect of the arc surface of the separation roller 7, the die cut Mylar sheet product automatically falls into the conveyor belt 9 under the action of gravity. The die cut Mylar sheet moves with the conveyor belt 9 until the Mylar sheet abuts against the baffle 27. The infrared sensor real-time measures the distance between the Mylar sheet and the baffle 27. When the Mylar sheet contacts the baffle 27, the infrared sensor emits an electrical signal to the controller. The controller controls the conveyor belt 9 to stop conveying and starts the centering mechanism to center the Mylar sheet, so as to bend the Mylar sheet subsequently. After the Mylar sheet is centered, the Mylar sheet is placed on the bending mechanism by the micro six-axis robot. The bending mechanism is used to bend the Mylar sheet. After bending, the Mylar sheet is taken out by the micro six-axis robot. The Mylar sheet is continuously die cut and bent in a loop, which is high in automation degree and efficient and convenient.

[0051] The process of the centering mechanism centering the Mylar sheet is as follows: the first motor drives the first bidirectional threaded rod 12 to rotate, thereby controlling the two limiting blocks 11 to relatively approach each other. The connecting rod and the push plate 13 move synchronously with the corresponding limiting block 11, so as to center the Mylar sheet separated from the end of the conveyor belt 9.

[0052] The process of the bending mechanism bending the Mylar sheet is as follows: first, the positions of the abutting block 15 and the pressing block 19 are adjusted according to the size of the Mylar sheet and the bending position of the Mylar sheet. The second motor is started to drive the second bidirectional threaded rod 16 to rotate. The second bidirectional threaded rod 16 controls the two abutting blocks 15 to relatively approach or move away from each other, until the side, where the two abutting blocks 15 relatively move away from each other, corresponds to the bending position of the Mylar sheet. Then, the third motor is started to adjust the positions of the two pressing blocks 19, until the two pressing blocks 19 respectively face the two abutting blocks 15. After the pressing block 19 and the abutting block 15 are adjusted, the Mylar sheet to be bent is placed on the abutting block 15 by the micro six-axis robot. After stable placement, the rectangular frame 18 is controlled to move downward by the hydraulic lifting rod 17, until the pressing block 19 presses the Mylar sheet. Then, the telescopic cylinder 21 outside the pressing block 19 is started. The telescopic cylinder 21 drives the bending block 22 to move downward, thereby bending the Mylar sheet.

[0053] The above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
