Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for the lamination processing of flexible printed circuit boards, and particularly relates to a rapid curing device for the lamination of flexible printed circuit boards. Background Technique

[0002] Flexible printed circuit boards are generally also known as flexible circuit boards. They are a kind of highly reliable and extremely flexible printed circuit boards made of polyimide or polyester film substrates, with the characteristics of high wiring density, light weight, thin thickness, and good bendability. Lamination is a key step in the manufacturing process of flexible printed circuit boards. In this step, multiple layers of flexible materials are combined together through high temperature and high pressure to form an integral body, and a rapid curing device is used to assist in the processing during this process.

[0003] However, there are still some deficiencies in the current rapid curing devices. For example, most existing rapid curing devices use water cooling to cool the vacuum lamination cavity, resulting in the water temperature in the water storage tank rising rapidly with the increase of the usage time, which brings a certain interference to the subsequent cooling rate of the cooling mechanism, and thus there are certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model researches and improves the existing structural deficiencies, and provides a rapid curing device for the lamination of flexible printed circuit boards. Summary of the Invention

A water-cooled bearing plate is arranged in parallel directly below the lamination heating plate.

[0007] Furthermore, a hinge is installed on the outside of the vacuum lamination curing box through bolts. The other end of the hinge is installed with a sealing door through bolts. The sealing door forms a rotating structure with the vacuum lamination curing box through the hinge.

[0008] Furthermore, the outer side of the water-cooled bearing plate is fixedly connected to the inner side of the guiding slider, and the water-cooled bearing plate and the vacuum lamination curing box form a sliding structure through the guiding slider.

[0009] Furthermore, the heat dissipation assembly includes a bearing bracket, heat dissipation fins, metal heat conduction tubes and fixing plates. The heat dissipation fins are fixedly installed on the inner surface of the bearing bracket at equal intervals. The metal heat conduction tubes are fixedly installed inside the heat dissipation fins. The other ends of the metal heat conduction tubes are connected to the inside of the water storage tank. Fixing plates are symmetrically installed on the front and rear sides of the outer side of the bearing bracket.

[0010] Furthermore, the heat dissipation assembly further includes a driving motor, a reciprocating lead screw and an auxiliary heat dissipation mechanism. The driving motor is installed on the outer side of the bearing bracket. The output shaft of the driving motor is installed with a reciprocating lead screw through a coupling. The auxiliary heat dissipation mechanism is slidably connected to the inner surface of the bearing bracket.

[0011] Furthermore, the auxiliary heat dissipation mechanism includes a fixing bracket, T-shaped sliding strips, a connecting mechanism and a heat dissipation fan.

[0013] The utility model provides a rapid curing device for flexible printed circuit board lamination, and has the following beneficial effects:

[0014] 1. Through the provided metal heat conduction tubes, the heat of the water in the water storage tank can be automatically transported to the heat dissipation fins, and then heat dissipation is carried out through the cooperation of the heat dissipation fins, so as to achieve the purpose of automatic heat dissipation, thereby avoiding the situation that the water temperature in the water storage tank rises rapidly with the increase of the use time, which interferes with the subsequent cooling rate of the cooling mechanism. And through the provided reciprocating lead screw, when the driving motor operates, it can drive the auxiliary heat dissipation mechanism to move back and forth along the inner surface of the bearing bracket, so that the wind generated when the heat dissipation fan operates can be evenly blown to the outer surface of the heat dissipation fins, thereby further accelerating the heat dissipation speed of the heat dissipation assembly.

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figures 1 - 3As shown in the figure, a rapid curing device for flexible printed circuit board lamination includes a vacuum lamination curing box 1 and a water storage tank 9. An electric telescopic rod 4 is installed at the top of the vacuum lamination curing box 1 through bolts, and the extending end of the electric telescopic rod 4 is fixedly connected to a lamination heating plate 5 through bolts. And a water-cooled bearing plate 6 is arranged in parallel directly below the lamination heating plate 5. The water storage tank 9 is fixedly installed at the bottom of the vacuum lamination curing box 1, and a water pump 10 is installed on the back of the water storage tank 9. And a water delivery pipe 11 is installed on the right side of the water pump 10. Moreover, a return pipe 12 is installed on the back of the water storage tank 9. At the same time, heat dissipation components 13 are symmetrically installed on the left and right sides of the water storage tank 9. The heat dissipation component 13 includes a bearing bracket 131, heat dissipation fins 132, a metal heat conduction pipe 133 and a fixing plate 134. And heat dissipation fins 132 are fixedly installed at equal intervals on the inner surface of the bearing bracket 131. And a metal heat conduction pipe 133 is fixedly installed by embedding inside the heat dissipation fins 132. Moreover, the other end of the metal heat conduction pipe 133 is connected to the inside of the water storage tank 9. At the same time, fixing plates 134 are symmetrically installed on the front and back of the outside of the bearing bracket 131. The heat dissipation component 13 further includes a driving motor 135, a reciprocating lead screw 136 and an auxiliary heat dissipation mechanism 137. And the driving motor 135 is installed on the outside of the bearing bracket 131. And the output shaft of the driving motor 135 is installed with a reciprocating lead screw 136 through a coupling. And an auxiliary heat dissipation mechanism 137 is slidably connected to the inner surface of the bearing bracket 131. The auxiliary heat dissipation mechanism 137 includes a fixing bracket 1371, a T-shaped slide bar 1372, a connecting mechanism 1373 and a heat dissipation fan 1374. And T-shaped slide bars 1372 are symmetrically installed on the upper and lower sides of the fixing bracket 1371. The outside of the fixing bracket 1371 is fixedly connected to the inner side of the T-shaped slide bar 1372. And the fixing bracket 1371 and the bearing bracket 131 form a sliding structure through the T-shaped slide bar 1372. By setting the fixing bracket 1371 and the bearing bracket 131 to be a sliding structure, when the auxiliary heat dissipation mechanism 137 reciprocates back and forth along the inner surface of the bearing bracket 131, it is smoother and more stable. And a connecting mechanism 1373 is fixedly installed on the outer surface of the fixing bracket 1371. And the inside of the connecting mechanism 1373 is movably connected to the side of the reciprocating lead screw 136. At the same time, a heat dissipation fan 1374 is fixedly installed by embedding inside the fixing bracket 1371.

[0023] As Figure 1 and Figure 4As shown in the figure, an electric telescopic rod 4 is installed on the top of the vacuum laminating and curing box 1 through bolts. A hinge 2 is installed on the outside of the vacuum laminating and curing box 1 through bolts, and the other end of the hinge 2 is installed with a sealing door 3 through bolts. The sealing door 3 forms a rotating structure with the vacuum laminating and curing box 1 through the hinge 2. By setting the sealing door 3 and the vacuum laminating and curing box 1 to be a rotating structure, the sealing door 3 is convenient for the staff to quickly open. The extending end of the electric telescopic rod 4 is fixedly connected with a laminating heating plate 5 through bolts. A water-cooled bearing plate 6 is arranged in parallel directly below the laminating heating plate 5. Guide sliders 7 are symmetrically installed on the left and right sides of the water-cooled bearing plate 6. The outside of the water-cooled bearing plate 6 is fixedly connected to the inner side of the guide sliders 7. The water-cooled bearing plate 6 forms a sliding structure with the vacuum laminating and curing box 1 through the guide sliders 7. By setting the water-cooled bearing plate 6 and the vacuum laminating and curing box 1 to be a sliding structure, the water-cooled bearing plate 6 moves more smoothly and stably when lifting and lowering along the inner surface of the vacuum laminating and curing box 1. At the same time, a vacuum pump 8 is installed on the top of the vacuum laminating and curing box 1.

[0024] In summary, for the rapid curing device for flexible printed circuit board lamination, first, according to Figures 1 to 4In the structure shown, the staff member grasps the sealing door 3 and opens it by rotating the hinge 2. Then, the staff member places the flexible printed circuit board to be laminated on the top of the water-cooled carrier plate 6. Next, the staff member closes the sealing door 3 and turns on the vacuum pump 8 through the controller. When the vacuum pump 8 starts running, the inside of the vacuum lamination curing chamber 1 is pumped to a vacuum state. Then, the staff member turns on the electric telescopic rod 4 and the lamination heating plate 5 through the controller. When the electric telescopic rod 4 starts running, it drives the lamination heating plate 5 to move downward along the inner surface of the vacuum lamination curing chamber 1, so that the lamination heating plate 5 automatically laminates and cures the flexible printed circuit board on the top of the upper water-cooled carrier plate 6. Then, through the sliding of the guiding slider 7, the upper water-cooled carrier plate 6 moves downward as the lamination heating plate 5 presses down, so that the upper water-cooled carrier plate 6 laminates and cures the flexible printed circuit board on the top of the lower water-cooled carrier plate 6. When the lamination curing time reaches the set value, the staff member turns on the electric telescopic rod 4 through the controller and turns off the lamination heating plate 5. Then, the staff member turns on the water pump 10 through the controller. When the water pump 10 starts running, it transports the cooling water in the water storage tank 9 into the inside of the water-cooled carrier plate 6 through the water delivery pipe 11, so that the water-cooled carrier plate 6 automatically assists the flexible printed circuit board above it to drop to room temperature. Then, through the return pipe 12, the heat-exchanged cooling water automatically flows back into the inside of the water storage tank 9. At this time, the heat in the water body in the water storage tank 9 is quickly conducted to the heat dissipation fins 132 through the metal heat conduction pipe 133 and dissipated, so as to ensure that the water temperature in the water storage tank 9 does not rise rapidly. When the staff member finds that the heat on the outer surface of the heat dissipation fins 132 cannot be quickly dissipated, the staff member turns on the driving motor 135 and the heat dissipation fan 1374 through the controller. When the driving motor 135 starts running, it drives the reciprocating lead screw 136 to rotate inside the fixing plate 134. At this time, through the connection of the connecting mechanism 1373 and the sliding of the T-shaped slide bar 1372, the fixing bracket 1371 drives the heat dissipation fan 1374 to move back and forth along the inner surface of the bearing bracket 131, so that the wind generated when the heat dissipation fan 1374 operates can accelerate the heat dissipation speed of the heat dissipation fins 132.
