Description

Technical Field

[0001] This utility model relates to the field of electronic dry film packaging inner roll support technology, specifically an adjustable tension electronic dry film packaging inner roll support. Background Technology

[0002] Electronic dry film is a polymer material primarily used in the manufacturing process of printed circuit boards (PCBs). Upon exposure to ultraviolet light, it undergoes a polymerization reaction, forming a stable substance that adheres to the board surface, thus blocking electroplating and etching. Currently, after processing the electronic dry film, it is typically packaged by inward rolling. A support frame is an indispensable component in this inward rolling structure, primarily serving a supporting role. However, existing supports may result in the electronic dry film being either too tight or too loose during the inward rolling packaging process. Excessive tightness may cause the electronic dry film to break, while excessive looseness may affect the inward rolling effect. Therefore, an adjustable tension electronic dry film packaging inward rolling support has been invented. Utility Model Content

[0003] In view of the problems existing in the above and / or the existing adjustable tension electronic dry film packaging inner roll holder, this utility model is proposed.

[0004] Therefore, the purpose of this invention is to provide an adjustable tension electronic dry film packaging inner roll support that can solve the aforementioned existing problems.

[0006] An adjustable tension electronic dry film packaging inward roll support includes a base plate, with side plates fixedly installed at both ends of the top of the base plate. An inward roll assembly for inward roll of the electronic dry film is provided on the left side of the base plate. A detection assembly for detecting the tension of the electronic dry film is provided at the bottom middle part between the two sets of side plates. A third roller is rotatably connected to the top right side of the two sets of side plates via a bearing.

[0007] As a preferred embodiment of the adjustable tension electronic dry film packaging inner roll support described in this utility model, the inner roll assembly includes:

[0008] The first box body is fixedly installed at both ends of the top left side of the base plate;

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] This utility model provides an adjustable tension electronic dry film packaging inner roll support. Please refer to [link / reference]. Figures 1-5The device includes a base plate 10, with side plates 11 fixedly installed at both ends of the top of the base plate 10. The left side of the base plate 10 is provided with an inward rolling assembly for inward rolling the electronic dry film. The bottom middle part between the two sets of side plates 11 is provided with a detection assembly for detecting the tension of the electronic dry film. The top right side of the two sets of side plates 11 is rotatably connected to a third roller 40 through a bearing.

[0039] The inward rolling assembly includes: a first box body 20, a first cylinder 21, a connecting plate 22, a support block 23, a rotating shaft 24, a housing 25, a servo motor 26, a second box body 27, a second cylinder 28, a bearing plate 29, and a first roller 291;

[0040] The first box 20 is fixedly installed at both ends of the top left side of the base plate 10. The first cylinder 21 is fixedly installed in the first box 20. The piston rod of the first cylinder 21 is fixedly installed on the connecting plate 22. The support block 23 is fixedly installed on the top of the connecting plate 22. The rotating shaft 24 is rotatably connected to the support block 23 through the bearing. The box 25 is fixedly installed on one side of the support block 23. The servo motor 26 is fixedly installed in the box 25, and the output shaft of the servo motor 26 is fixedly connected to the rotating shaft 24. The opposite ends of the two sets of rotating shafts 24 are fixedly installed with the second box 27 through the flange. The second cylinder 28 is fixedly installed in the second box 27. The second cylinder 28 is preferably the cylinder in patent CN105402197A. The piston rod of the second cylinder 28 is fixedly installed on the bearing plate 29. The opposite ends of the two sets of bearing plates 29 are fixedly installed with the first roller 291 through the chuck. The materials of the first box 20, the box 25 and the second box 27 can be made of aluminum alloy as required.

[0041] The detection components include: a horizontal plate 30, a pressure sensor 31, a U-shaped plate 32, and a second roller 33;

[0042] A horizontal plate 30 is fixedly installed at the bottom center between the two sets of side plates 11. A pressure sensor 31 is fixedly installed on the bottom of the horizontal plate 30. A U-shaped plate 32 is fixedly installed on the bottom of the pressure sensor 31. A second roller 33 is rotatably connected to the U-shaped plate 32 through a bearing.

[0043] In practical use, the specific steps are as follows:

[0044] First, the first roller 291 is placed between two sets of support plates 29. Then, the first roller 291 is fixed between the two sets of support plates 29 by the cooperation of the second cylinder 28 and the chuck. Next, one end of the electronic dry film passes through the third roller 40 and the second roller 33 in sequence and is fixed on the first roller 291. Then, the first roller 291 is wound inward by the servo motor 26. During this process, if the value on the pressure sensor 31 exceeds the set value range, it means that the electronic dry film is too taut. The first roller 291 will be lowered by the first cylinder 21 until the pressure sensor 31 is within the set value range. Conversely, if the value on the pressure sensor 31 does not reach the set value range, it means that the electronic dry film is too loose. The first roller 291 will be raised by the first cylinder 21 until the pressure sensor 31 is within the set value range. In this way, the tension of the electronic dry film can be adjusted.
