Description

Technical Field

[0001] The utility model relates to the technical field of dry film manufacturing, in particular to a film pressing and leveling machine for avoiding abnormal film lamination on a substrate. Background Art

[0002] Dry film is a polymer material relative to wet film. It can produce a polymerization reaction after being exposed to ultraviolet light, forming a stable substance attached to the board surface, thereby achieving the function of blocking electroplating and etching. Dry film is an important consumable material for making printed circuit boards and is widely used in the microelectronics industry and circuit board manufacturing industry.

[0003] In the existing technology, after setting up a new dry film roll, personnel need to manually measure the thickness of the dry film roll first, and input the measured thickness data into the pre-lamination section film machine computer. The film machine automatically calculates the number of substrates that can be filmed, and alarms when the number of production sheets reaches the warning number, reminding personnel to replace the film roll. However, in the actual operation process, there will be some different usage situations, resulting in the failure of the warning function. When there are problems such as film rolling, film jamming, film skewness, and film wrinkles, the length of the dry film with problems will be removed, resulting in inaccurate calculation of the dry film roll usage length, and some substrates are scrapped due to insufficient film lamination length.

[0004] Therefore, it is urgent to provide a film pressing and leveling machine that can avoid abnormal film lamination on substrates, so as to avoid the problem that when the dry film is used up during operation, the personnel fail to replace the film roll in time, resulting in incomplete film lamination and scrapping of the substrate.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0033] like Figure 2 As shown, the present application provides a film laminating and leveling machine for avoiding abnormal film laminating of substrates, comprising a pre-laminating mechanism, a conveying mechanism, a conveying film output mechanism, a vacuum mechanism, a flattening mechanism and a conveying film recovery mechanism, wherein the output end of the pre-laminating mechanism is connected to the input end of the conveying mechanism, the output end of the conveying mechanism is connected to the input end of the conveying film output mechanism, the output end of the conveying film output mechanism is connected to the input end of the vacuum mechanism, the output end of the vacuum mechanism is connected to the input end of the flattening mechanism, and the output end of the flattening mechanism is connected to the input end of the conveying film recovery mechanism;

[0035] In some embodiments, the lamination leveling machine further includes an alarm device, and when the laser sensing device detects that the thickness of the dry film on the dry film cylinder is less than a preset value, the alarm device starts to work.

[0036] In some embodiments, the laminating and leveling machine further includes a PLC control module.

[0037] like Figure 3 As shown, when the laser sensing device detects that the thickness of the dry film on the dry film tube is less than a preset value, the laser sensing device sends a signal.
