[0040] The above two modes can effectively reduce the alignment difficulty and manual operation amount during packaging, further highlighting the automation advantage and high packaging performance of the device.

[0041] When working: first, the electronic product is placed in the positioning groove 84 formed by the positioning piece 8, ensuring that the electronic product is clamped and fixed by the first plate 81, the second plate 82 and the third plate 83. Then, the unwinding roller 2 and the winding roller 3 on the device are started, so that the film is unfolded and kept in moderate tension under the action of the tensioning assembly; specifically, the tensioning motor drives the tensioning screw 62 to rotate, thereby driving the tensioning roller 63 to make fine adjustments, so that the film tension at both ends of the unwinding and winding is in the appropriate range, preventing the film from being too loose or too tight during the conveying process. When the electronic product and the film are ready, the lower pressing assembly starts to work, and the hydraulic rod 7 arranged between the support frame 4 and the lifting plate 51 pushes the lifting plate 51 downward, so that the device enters the film covering station.

Then, the drive motor drives the moving frame 532 to reciprocate left and right through the drive screw 531, and the smoothing roller 52 and the heating piece 54 installed on the moving frame 532 move synchronously: the smoothing roller 52 slowly rolls along the surface of the film to eliminate possible wrinkles or bubbles; the airflow blown by the fan 542 is heated by the heating resistance wire 543 to form hot air, which is uniformly released from the top and bottom of the heating mounting frame 541 with the through slot 544 area, and applies moderate heat to the film, so that it shrinks slightly and adheres to the surface of the electronic product. During the hot covering process, if it is necessary to trim the excess film, the lifting plate 51 is moderately pressed to make the cutting knife 55 contact with the film, and the film cutting operation is quickly completed. Through this step, the coverage range of the film can be accurately controlled, effectively ensuring the adhesion from the edge to the center of the shell surface. Finally, after the smoothing and hot covering are completed, the winding roller 3 continues to collect the excess film, and the operator takes out the film-coated and packaged electronic product from the positioning groove 84, which can realize high-quality, tightly adhered and no obvious bubble or wrinkle packaging effect. The whole process does not need complicated manual intervention, through the uniform downward pressure applied by the hydraulic rod 7 and the constant tension maintained by the tensioning assembly, combined with the efficient cooperation of the smoothing roller 52 and the heating piece 54, the film covering quality and production efficiency are significantly improved.

[0042] In summary, the electronic product packaging film smoothing device can realize close adhesion of the film and the surface of the electronic product, reduce bubbles and wrinkles, improve packaging efficiency and product quality, and has high overall automation degree, good adaptability to electronic products of different sizes or shapes, thereby meeting the demand for high-quality film packaging and improving market competitiveness; the airflow blown by the fan 542 is heated by the heating resistance wire 543 to form hot air, which directly reaches the film area covering the surface of the electronic product, so that the film can be synchronously subjected to heat covering treatment during the smoothing process, thereby moderately shrinking and being more closely adhered to the surface of the product; at the same time, the air supply of the fan 542 can effectively reduce the risk of local high temperature of the heating part, avoid excessive damage or carbonization of the film, improve the overall film quality and efficiency, realize rapid, uniform and controllable heat covering operation on electronic products of different sizes or structures, significantly reduce bubbles and wrinkles, and meet the demand for high-quality film covering; the pressing block 561 and the spring 562 can preliminarily fix the film to prevent displacement or wrinkles of the film during the smoothing and heat covering process, also can reduce the collision force between the pressing block 561 and the electronic product, avoid damage of the electronic product or the pressing block 561, and improve the service life of the pressing block 561 and the quality of the electronic product; the tensioning assembly can accurately control the contact position or height of the tensioning roller 63 and the film, so that the film maintains constant and appropriate tension during film covering and smoothing operation, effectively avoids bubbles or wrinkles caused by excessive loose tension, and prevents excessive tension from causing film stretching or damage.
