Abstract
Description
Technical Field
[0001] The present invention relates to the technical field related to circuit board production, in particular to a printed circuit board laminating device which can be adjusted in real time with compaction. Background Art
[0002] Transferring the inner PCB layout begins with creating the two layers of circuitry on the center core board. After the copper-clad laminate is cleaned, a photosensitive film is applied to its surface. This film solidifies when exposed to light, forming a protective film on the copper foil of the copper-clad laminate.
[0003] The surface of the film is uneven. Only under appropriate pressure can the molten hot melt adhesive completely cover the printed product, achieving a glossy finish and a good bond. Low pressure results in a weak bond, while higher pressure improves the bond between the film and the product. However, excessive pressure can easily cause wrinkles in the product and damage and deform the rubber roller, shortening its lifespan. Increasing pressure increases the contact pressure between the rubber roller and the heated drum, placing increased load and wear on the axle heads and bearings of both wheels. It also places increased strain on the transmission system, shortening the lifespan of the entire machine.
[0004] In actual production, pressure should be adjusted according to the type of film. For example, for loose films, higher pressure is required, and for loose films, lower pressure is required. While existing laminating machines do have pressure adjustment capabilities, this requires pre-setting based on the characteristics of the PCB surface and the film tension. Printed PCB surfaces are not smooth and flat. Therefore, during lamination, the laminating pressure is generally set between 8 and 25 MPa. However, this still results in uneven adhesion between different parts of the PCB (caused by the unevenness of the PCB). Summary of the Invention

DETAILED DESCRIPTION
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0035] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0036] See also Figure 1-9 In an embodiment of the present invention, a printed circuit board laminating device that is adjusted in real time with compression includes a base 1 and two risers 2 fixed to the base 1, and further includes:
[0037] The mounting frame 28 is movably arranged between the two vertical plates 2 through a power mechanism. A heating roller 4 is rotatably installed on the mounting frame 28, and a rubber roller 5 is provided through a pressure conversion mechanism. A collection device 3 is also movably provided through a reciprocating drive mechanism. The reciprocating drive mechanism is connected to the power mechanism through a transmission mechanism.
[0038] It should be pointed out that each of the two vertical plates 2 is provided with a through hole for allowing the film to pass through. During the specific operation, the film is passed through the two through holes in turn, and the film bypasses the rubber roller 5 and the heating roller 4 (the film is located on the upper part of the heating roller 4 and on the lower part of the rubber roller 5), and it is ensured that there is a certain pulling force at both ends of the film, that is, the film is ensured to be in a straight state.
[0039] Among them, it should be supplemented that a groove is also provided on the base 1 to form a placement position for positioning the circuit board to be processed. The collection device 3 is a sensor component. When the device is working, the reciprocating drive mechanism can drive the collection device 3 to perform reciprocating linear motion above the circuit board to collect the concave and convex information on the surface of the circuit board, and send the collected information to the calculation module for averaging processing. Subsequently, the calculation module communicates with the pressure conversion mechanism through the calculated results, so that the rubber roller 5 applies an appropriate pressure to the circuit board to prevent the poor adhesion due to low pressure; excessive pressure causes wrinkles in the product, which can easily damage and deform the surface of the rubber roller 5, thereby reducing the service life of the rubber roller 5.
[0040] Please refer again Figure 2 The power mechanism includes a Maltese cross movement assembly mounted on one of the vertical plates 2 and a screw drive assembly provided between the two vertical plates 2. The Maltese cross movement assembly includes a driving wheel 13 rotatably mounted on the vertical plate 2, a first driven wheel 14, a second driven wheel 15, and a first motor 11 mounted on the vertical plate 2.
[0041] The output end of the first motor 11 is connected to the rotating shaft of the driving wheel 13 , and the rotating shafts of the first driven wheel 14 and the second driven wheel 15 are respectively connected to the transmission mechanism and the threaded drive assembly.
[0042] The screw drive assembly includes a first screw rod 6 rotatably mounted between the two vertical plates 2, a guide rod 7 fixedly mounted between the two vertical plates 2, and a transverse plate 8 provided on the first screw rod 6. The transverse plate 8 is threadedly connected to the first screw rod 6, the mounting bracket 28 is fixed to the transverse plate 8, and the guide rod 7 passes through the transverse plate 8 and is slidably connected thereto. The first screw rod 6 is connected to the rotating shaft of the second driven wheel 15 via a third transmission belt 36.
[0043] When the first motor 11 is working, it will drive the driving wheel 13 to rotate, so that the driving wheel 13 can drive the first driven wheel 14 and the second driven wheel 15 to rotate alternately. When the first driven wheel 14 rotates, its rotating shaft can drive the reciprocating drive mechanism to move through the transmission mechanism, and the reciprocating drive mechanism drives the collection device 3 to move linearly along the width direction of the base 1 to realize the collection of concave and convex information on the circuit board. When the second driven wheel 15 rotates, its rotating shaft will drive the first screw 6 to rotate through the third transmission belt 36, and the guide rod 7 guides the transverse plate 8, so that the transverse plate 8 and the first screw 6 are threadedly matched and move along the length direction of the base 1, thereby realizing the lamination action of the rubber roller 5 on the circuit board.
[0044] Please refer again Figure 6-8 The pressure conversion mechanism includes a lifting plate 20 that is movably arranged at the bottom of the transverse plate 8 through a deflection lifting structure, and an elastic pressure component installed on the lifting plate 20 and connected to the rubber roller 5.
[0045] Two upright posts 21 are fixedly mounted on the bottom of the transverse plate 8, and the lifting plate 20 is slidably mounted on the two upright posts 21. The deflection and lifting structure includes a deflection plate 19 rotatably mounted on the bottom of the transverse plate 8 and a column 1901 fixed to the deflection plate 19. A strip-shaped deep groove is formed on the side of the lifting plate 20 facing the deflection plate 19, and the column 1901 extends into the strip-shaped deep groove and is slidably connected to the lifting plate 20.
[0046] A gear 16 is also rotatably mounted on the transverse plate 8. The rotating shaft of the gear 16 is connected to the rotating shaft of the deflection plate 19 through the first bevel gear set 18, and a through hole 1601 is provided on the rotating shaft of the gear 16. A long rod 17 is fixed between the two vertical plates 2. The long rod 17 is provided with a section of teeth meshing with the gear 16, and is also fixed with an insertion rod 1701 adapted to the through hole 1601.
[0047] Specifically, the first bevel gear set 18 includes a first bevel gear fixedly mounted coaxially with the gear 16 and a second bevel gear fixedly mounted coaxially with the deflection plate 19 , and the second bevel gear is meshed with the first bevel gear;
[0048] When the device is working, in the first stroke of the movement of the transverse plate 8, the gear 16 will cooperate with the teeth on the long rod 17 to rotate, and then the rotating shaft of the gear 16 drives the deflection plate 19 to deflect downward 90° through the first bevel gear set 18. Under the guidance of the two columns 21, the column 1901 slides with the lifting plate 20 through the strip-shaped deep groove, so that the lifting plate 20 drives the rubber roller 5 to descend and press the film onto the circuit board. As the transverse plate 8 continues to move, the insertion rod 1701 will pass through the through hole 1601 to fix the gear 16, so that the state of the rubber roller 5 at this time is maintained stable. At this time, according to the information feedback from the collection device 3, the elastic pressure component automatically moves to adjust the pressure of the rubber roller 5;
[0049] This repetitive cycle allows the lamination pressure to be adjusted in real time according to the characteristics of the circuit board surface, thereby ensuring that the lamination pressure is within a relatively flat range as much as possible. Compared with the existing pressure range of 8 to 25 MPa, the pressure range value changes less, thereby ensuring that the adhesion pressure at various locations on the circuit board is relatively constant, which will neither cause damage to the circuit board, wrinkles in the film, nor problems with weak adhesion.
[0050] The elastic pressure assembly includes a second motor 12 mounted on the lifting plate 20, a second screw rod 22 rotatably mounted on the bottom of the lifting plate 20 and connected to the output end of the second motor 12, and a threaded sleeve 23 sleeved on the second screw rod 22 and threadedly connected thereto;
[0051] A pressure plate 24 is fixed to the end of the threaded sleeve 23 away from the lifting plate 20. Two connecting rods 25 are slidably mounted on the pressure plate 24. An assembly plate 26 is fixed to the ends of the two connecting rods 25 away from the lifting plate 20. The rubber roller 5 is rotatably mounted on the bottom of the assembly plate 26. A cylindrical spring 27 is also sleeved on the outer circumference of each of the two connecting rods 25. The ends of the cylindrical springs 27 respectively connect the pressure plate 24 and the assembly plate 26.
[0052] Among them, the second motor 12 communicates with the acquisition device 3. After the data collected by the acquisition device 3 is processed, the second motor 12 will drive the second screw rod 22 to rotate. Accordingly, the threaded sleeve 23 is threadedly engaged with the second screw rod 22, and pushes the pressure plate 24 to slide upward or downward on the two connecting rods 25. The compression amount of the cylindrical spring 27 and the pressure of the rubber roller 5 are reduced or increased, thereby realizing real-time adjustment of the pressure.
[0053] It should be emphasized that a guide structure (not shown in the figure) is also provided between the threaded sleeve 23 and the lifting plate 20. The guide structure includes a vertical rod fixed on the threaded sleeve 23. The vertical rod is in an upright state and passes through the lifting plate 20 and is slidingly connected to the lifting plate 20. The setting of the guide structure guides the lifting and lowering action of the pressure plate 24 to prevent the rubber roller 5 from twisting on the film when the second screw 22 rotates, thereby causing the film to wrinkle.
[0054] Both the first motor 11 and the second motor 12 are servo motors with bidirectional drive output ends, so as to realize the forward or reverse rotation of the first screw rod 6 and the second screw rod 22, thereby facilitating the reset of each component and increasing or decreasing the compression amount of the cylindrical spring 27.
[0055] Please refer again Figure 5 and Figure 9 The reciprocating drive mechanism includes two driving wheels 31 rotatably mounted on the bottom of the mounting frame 28, a connecting member 32 rollingly connecting the two driving wheels 31, and a driving column 3201 provided on the connecting member 32;
[0056] The rotating shaft of one of the driving wheels 31 is connected to the transmission mechanism, and two cross bars 33 are fixed to the bottom of the mounting frame 28. A reciprocating plate 34 fixed to the collection device 3 is slidably provided on the two cross bars 33, and a limiting depth groove is provided on the reciprocating plate 34. The driving column 3201 extends into the limiting depth groove and is slidably connected to the reciprocating plate 34.
[0057] The transmission mechanism includes a rotating shaft 9 rotatably mounted between the two vertical plates 2 and a sleeve 10 rotatably mounted on the mounting frame 28. The rotating shaft 9 is connected to the rotating shaft of the first driven wheel 14 via a second transmission belt 35. The sleeve 10 is slidably engaged with the rotating shaft 9 via a limiting structure, and is further connected to the rotating shaft of the driving wheel 31 via a first transmission belt 29 and a second bevel gear set 30.
[0058] The limiting structure includes a plurality of strip-shaped protrusions fixedly arranged on the outer periphery of the rotating shaft 9 at equal intervals along the circumference, and a plurality of strip-shaped grooves opened on the inner wall of the sleeve 10 at equal intervals along the circumference. The strip-shaped grooves are adapted to the strip-shaped protrusions, and both are parallel to the central axis of the rotating shaft 9.
[0059] Furthermore, the second bevel gear set 30 includes a number 3 bevel gear rotatably mounted on the mounting frame 28 and a number 4 bevel gear coaxially fixedly mounted with one of the driving wheels 31 , the number 4 bevel gear meshing with the number 3 bevel gear, and the first transmission belt 29 is used to connect the rotating shaft of the number 3 bevel gear and the sleeve 10 .
[0060] When the first driven wheel 14 rotates, its rotating shaft drives the rotating shaft 9 to rotate through the second transmission belt 35, and the rotating shaft 9 drives the sleeve 10 to rotate through the strip-shaped protrusions on its outer wall and the strip-shaped grooves on the inner wall of the sleeve 10. Then, the sleeve 10 drives the driving wheel 31 to rotate through the first transmission belt 29 and the second bevel gear set 30.
[0061] The driving wheel 31 rotates, which will drive the driving column 3201 to move through the connecting piece 32, and the movement trajectory of the driving column 3201 is consistent with the shape of the connecting piece 32. The driving column 3201 drives the reciprocating plate 34 to slide on the two cross bars 33 through the limiting deep groove, thereby realizing the collection action of the collection device 3 on the convex and concave information of the circuit board surface.
