Description

[0002] Dry film is an important material in the PCB manufacturing process, used to transfer and make circuit board graphics. In the laminating process, the dry film is first pre-attached to the surface of the copper-clad board, and then the laminating is completed by vacuum lamination, which can improve the filling performance and adhesion between the dry film and the copper-clad board surface, thereby improving the yield and quality of the PCB. The existing pre-laminating machine can improve the efficiency of pre-laminating, reduce the problems of wrinkling, inaccurate margins, and adhesion of dry film to the board edge during pre-laminating, but there are still the following shortcomings:

[0003] 1. Traditional pre-lamination machines support dry film through fixed film suction plates, knife grooves and guide blocks. When the film is moving, friction will occur between the film surface and the supporting surface, posing the risk of scratching the dry film.

[0004] 2. When the copper clad board needs to use a thicker dry film with a thickness of at least 2.0 mil (mil means milliinch) under special requirements, the traditional film suction plate has weak suction force and cannot firmly absorb the thick dry film and transport it to the designated pre-lamination position, which will lead to problems such as inaccurate PCB margins, film tilt, and pre-lamination film falling off.

[0040] Figure 3 The schematic diagram of the structure of the film guide module 5 and the material discharging conveying module 6 in the frictionless pre-laminating machine for protecting the film surface of the dry film according to the embodiment of the utility model is shown. Figure 3 The film guide module 5 includes: a first film guide mechanism (i.e., an upper film guide mechanism) and a second film guide mechanism (i.e., a lower film guide mechanism) of the same structure, a second mounting bracket 56 and a fifth cylinder 57. Among them, the second mounting bracket 56 is arranged on the positive conveying side of the film suction disc 342; the first film guide mechanism and the second film guide mechanism are symmetrically arranged on both sides of the copper clad board P along the vertical direction, and the first film guide mechanism includes a first film guide roller 51, a fourth cylinder 54, a second film guide roller 52, and a third film guide roller 53 arranged in sequence along the vertical direction. The first film guide roller 51 is arranged on the first mounting bracket 36 and is located between the film suction disc 342 and the second cylinder 341. The second film guide roller 52, the third film guide roller 53, the fourth cylinder 54, The film tail conveying mechanism 55 is arranged on the second mounting bracket 56, the second film guide roller 52 and the fourth cylinder 54 are located at the lower end of the film suction disk 342, the third film guide roller 53 is adjacent to the copper clad board P, the fourth cylinder 54 is connected to the third film guide roller 53, and is used to push the third film guide roller 53 along the vertical slide rail on the second mounting bracket 56 to approach the copper clad board P, and the fifth cylinder 57 is fixed on the frame 1 and connected to the second mounting bracket 56, and is used to push the second mounting bracket 56 to move toward the pre-lamination station S in the reverse direction of conveying.

[0041] Specifically, the first film guiding mechanism further includes a film tail conveying mechanism 55 adjacent to the third film guiding roller 53, and the film tail conveying mechanism 55 includes a motor ( Figure 3The film tail support plate 551 is driven by the motor to rotate to support the film tail and smoothly convey the dry film M. In order to prevent the dry film M from falling or wrinkling, a plurality of adsorption holes for adsorbing the dry film M are provided on the surface of the film tail support plate 551 facing the dry film M.

[0042] Specifically, the discharge conveying module 6 includes: a plurality of discharge conveying rollers 61 and a clamping and transferring mechanism 62, wherein the plurality of discharge conveying rollers 61 are connected to the fifth cylinder 57 in the film guide module 5, and the plurality of discharge conveying rollers 61 can be driven by the fifth cylinder 57 to move in the direction opposite to the conveying direction and perpendicular to the copper clad board P, and the clamping and transferring mechanism 62 is driven by a motor ( Figure 3 The copper-clad board P after pre-lamination of the dry film M is driven by a pre-lamination station S.

[0043] The frictionless pre-laminating machine for protecting the film surface of the dry film provided by the utility model first installs the dry film M during operation, installs the dry film M on the film frame 31, manually pulls the film through the second guide roller 321 and the dry film stripping plate 33, separates the protective layer of the dry film M, namely the PE film, from the photosensitive adhesive film, and the PE film is returned to the PE film collecting roller 312 along the first guide roller 311, and the photosensitive adhesive film is vertically stretched to a length exceeding the cutting knife mechanism 351 by the first film guide roller 51, and then the film is cut by the cutting knife mechanism 351, and the film suction disc 342 is evacuated, and the photosensitive adhesive film is adsorbed on the surface of the film suction disc 342 by the vacuum negative pressure function of the film suction disc 342;

[0044] Then, the dry film M is pre-laminated, and the copper-clad laminate P is transported to the centering mechanism 22 by multiple feeding conveying rollers 21 and then transported to the pre-lamination station S. The second cylinder 341 pushes the film suction plate 342 to move vertically toward the copper-clad laminate P until the photosensitive adhesive film is firmly attached to the front end of the copper-clad laminate P, and then the vacuum state of the film suction plate 342 is stopped and reset;

[0045] Then, the copper-clad board P with the pre-laminated dry film M is sent away from the pre-laminated station S, and the fifth cylinder 57 pushes the second mounting bracket 56 together with the plurality of discharge conveying rollers 61 to move toward the pre-laminated station S. The motor drives the clamping and transferring mechanism 62 to approach the copper-clad board P with the pre-laminated dry film M, and clamps the front end of the copper-clad board P and the dry film M. The plurality of discharge conveying rollers 61 rise to the same height as the feeding conveying module 2. At this time, the dry film M leaves the surface of the film suction disk 342, and the dry film M is supported by the first film guide roller 51, the second film guide roller 52, and the third film guide roller 53. The dry film M is in a stationary state relative to the rolling first to third film guide rollers 51, 52, 53, and there is no friction, so the dry film M will not be scratched;

[0046] Then, the dry film M is pre-laminated and cut. The motor drives the clamping and transferring mechanism 62 to move in the opposite direction of the conveying. The fourth cylinder 54 pushes the third film guide roller 53 to approach the copper-clad board P in the vertical direction, so that the dry film M can be better attached to the board surface of the copper-clad board P. When the dry film M has traveled to a set length, the copper-clad board P stops conveying. The third cylinder 353 pushes the knife groove mechanism 352 to approach the dry film M. The dry film M is adsorbed and fixed by the vacuum negative pressure function of the adsorption holes on the knife groove surface, and then the film is cut by the knife mechanism 351.

[0047] Finally, the copper-clad board P with the pre-attached dry film M is sent away. After the dry film M is cut, the tail of the dry film M is still adsorbed by the knife groove and will not fall off. The clamping and transferring mechanism 62 continues to move. Before the tail of the dry film M leaves the knife groove, the motor of the film tail conveying mechanism 55 is started to rotate the film tail support plate to support the film tail of the dry film M and enable the dry film M to be smoothly conveyed. Several adsorption holes on the surface of the film tail support plate 551 adsorb the dry film M through vacuum negative pressure, effectively preventing the dry film M from sagging and wrinkling. The clamping and transferring mechanism 62 moves further until the tail of the copper-clad board P with the pre-attached dry film M leaves the pre-attaching station S and is released. Multiple discharge conveying rollers 61 send the copper-clad board P with the pre-attached dry film M away for the next process step, and the film guide module 5 is reset at the same time.

[0048] Figure 4 The schematic diagram of the structure of the pre-film laminating mechanism 34 in the frictionless pre-film laminating machine for protecting the film surface of the dry film according to the embodiment of the utility model is shown. Figure 4 When some copper-clad boards P with special requirements need to use a thicker dry film M, such as a dry film M with a thickness of at least 2.0 mil, the pre-lamination mechanism 34 also includes: an auxiliary adsorption unit, the auxiliary adsorption unit includes a heater 343 and a blowing assembly 345, the film suction plate 342 includes a flat adsorption surface 3421 and a curved adsorption surface 3422, the heater 343 is arranged at the bottom end of the flat adsorption surface 3421 of the film suction plate 342, the heat generated by the heater 343 is transferred to the dry film M through the film suction plate 342 to soften the dry film M, and the blowing assembly 345 is arranged above the cutting knife mechanism 351, and the airflow blown by the blowing assembly 345 helps the softened dry film M to be more evenly adsorbed on the film suction plate 342.

[0049] Specifically, the heater 343 is a heating tube.

[0050] Furthermore, in order to better control the temperature of the dry film M to improve the adsorption effect of the dry film M, the pre-film laminating mechanism 34 also includes: a dry film temperature control unit, the dry film temperature control unit includes a temperature sensor 344 and a temperature controller, the temperature sensor 344 is also arranged at the bottom end of the planar adsorption surface 3421 of the film suction disk 342 and is adjacent to the dry film M, and is used to monitor the temperature of the dry film M. The temperature controller controls the heating value of the heater 343 according to the temperature of the dry film M monitored by the temperature sensor 344. Specifically, when the temperature of the dry film M is too high, the heater 343 is controlled to reduce the heating value or even directly stop heating, or when the temperature of the dry film M is too low, the heater 343 is controlled to increase the heating value.

[0051] Specifically, the temperature sensor 344 is a thermocouple.

[0052] In summary, the utility model provides a frictionless pre-laminating machine that can protect the film surface of the dry film. By setting the film guide module 5, the dry film M can be supported by the first film guide roller 51, the second film guide roller 52, and the third film guide roller 53 of the film guide module 5 when the dry film M is moving. The dry film M is stationary and frictionless relative to the rolling film guide rollers 51, 52, and 53, thereby avoiding scratching the dry film M. In addition, the film tail support plate 551 allows the dry film M to be smoothly transported, and the adsorption holes on the film tail support plate 551 prevent the dry film M from falling and wrinkling. Under special requirements, when the copper clad board P needs to use a thicker dry film such as a dry film with a thickness of at least 2.0 mil, by setting the heater 343 and the blowing component 345, the dry film M can be softened and the softened dry film M can be more evenly adsorbed on the film suction plate 342, thereby solving the problems of inaccurate PCB margins, film tilting, and pre-laminating film falling.
