Description

Technical Field

[0001] The utility model relates to the technical field of laminating devices, in particular to a double-sided laminating device. Background Art

[0002] Film is a thin, soft, transparent sheet. Made of plastic, adhesive, rubber or other materials, there are optical films, composite films, superconducting films, polyester films, nylon films, plastic films, etc. Films are widely used in electronics, machinery, printing and other industries. Electronic semiconductor functional devices and optical coatings are the main applications of film technology.

[0003] A Chinese utility model with authorization announcement number CN216832207U discloses a double-sided automatic positioning die-cutting and laminating device for a thin film. When in use, the device cuts the thin film on the electronic substrate through the cooperation of a cutting knife and a knife groove. However, when used specifically, the device has certain defects. For example, the position of the cutting knife is fixed. When the pressing plate is pressed down, the film may contact the cutting knife in advance, which will cause the action of the pressing plate and the cutting knife to be uncoordinated, thereby affecting the cutting and laminating effect and increasing the scrap rate. Therefore, it is necessary to redesign a double-sided laminating device to address the above problems. Utility Model Content

[0021] During specific use, the set pressure plate 13 drives the film to contact the electronic substrate in advance, so that the film is tightly attached to the electronic substrate, and then under the reaction force, drives the slide bar 10 to slide upward, the position of the pressure plate 13 remains unchanged, and the cutting knife 7 slides downward horizontally to cut the film. At the same time, the pressure plate 13 is always pressed on the electronic substrate to avoid affecting the cutting and bonding effects. It should be noted that in order to avoid damage to the electronic substrate caused by excessive pressure of the pressure plate 13, the set spring 12 is relatively weak.

[0022] Reference Figure 2 and Figure 3 The telescopic mechanism includes an electric telescopic rod 3 fixedly connected to the upper end surface of the side plate 2, the telescopic end of the electric telescopic rod 3 is fixedly connected to the slide plate 9, a plurality of through grooves are provided on the upper end surface of the processing plate 8, the radius of the limit block 11 is greater than the radius of the slide rod 10, the inner wall of the cutting knife 7 and the outer wall of the pressing plate 13 are both square, the inner wall of the cutting knife 7 contacts the outer wall of the pressing plate 13, the side plate 2 is mounted on the upper end surface of the plate body 1 by screws, the length of the film roller 4 and the feeding roller 6 is consistent with the width of the frame 5; when in use, the cutting knife 7 cuts downward along the outer wall of the pressing plate 13 to avoid cutting errors caused by offset or tilt, thereby improving the cutting accuracy.

[0023] In the utility model, the specific function of the device is as follows: when using the device, the main body of the film is rolled up on the outer walls of the two film rollers 4, and the other end passes through the frame 5 and is rolled up on the outer walls of the two groups of feeding rollers 6. At this time, the lower film is in contact with the upper end surface of the processing plate 8, and there is a certain gap between the two groups of films. The electronic substrate is placed between the two groups of films. At this time, the lower film is in contact with the motor substrate, and then the slide plate 9 is driven to slide downward with the help of the telescopic end of the electric telescopic rod 3. During the sliding process, the film is driven to contact with the upper end surface of the electronic substrate until the pressure plate 13 generates a reaction force, driving the slide bar 10 to slide upward, and synchronously driving the spring 12 to stretch. At this time, the position of the pressure plate 13 remains unchanged, and the set cutting knife 7 still slides downward, thereby cutting the two groups of films in contact. In this way, it can be ensured that the film is tightly and evenly bonded to the electronic substrate before cutting. At the same time, during the cutting process, the pressure plate 13 is always pressed on the electronic substrate to avoid affecting the cutting and bonding effects and reduce the scrap rate.
