Description

Technical Field

[0001] The invention belongs to the technical field of PCB soft board processing, and in particular relates to a PCB soft board processing thermal curing device. Background Art

[0002] PCB soft board, also known as flexible circuit board (FPC), its softness mainly depends on its substrate and structural design. During the production and processing of PCB soft board, it is not fully cured in the intermediate state, and its softness is between solid and liquid. It has a certain shape retention ability and bendability, and has a certain flexibility. It needs to be transferred to the heating and curing equipment for curing treatment to achieve complete curing and maintain a certain structural strength. PCB soft board processing heat curing equipment is an indispensable part of the PCB (printed circuit board) production process.

[0003] In the prior art, the PCB soft board processing heat curing equipment is used for the PCB soft board in the intermediate state. When performing the curing process, the PCB soft board to be cured is usually placed in a placement frame and moved to the heat curing zone for heating and curing. However, during the actual curing process, only the top surface of the PCB soft board in the placement frame can effectively and fully receive the ambient heat, while the bottom surface is difficult to quickly and effectively absorb the ambient heat, which makes the thermal stress on the upper and lower surfaces of the PCB soft board uneven, thereby causing the PCB soft board to bend and deform during the curing process. During the heating and curing process of the actual PCB soft board, due to uneven heating, the molded PCB board has structural deformation, which greatly reduces the yield rate of production and processing, and the actual use effect is not good.

[0004] In addition, in the prior art, the PCB soft board processing heat curing equipment has a limited time for each PCB soft board to enter the heating zone for heating when performing continuous batch heating and curing treatment. Both the loading and unloading steps require additional loading and unloading processing procedures, which makes it impossible to further improve the continuous production and processing speed. The overall production and processing efficiency is low. The continuous processing steps from loading, curing to unloading all need to be processed independently, which is inefficient and has poor use effect. Summary of the invention

[0035] The composite processing assembly 18 includes a fixed cover 181 , a first magnetic plate 182 and an elastic air bag tube 183 , and the first magnetic plate 182 is fixed in the fixed cover 181 .

[0036] Embodiment 1: When in use, the PCB soft board to be cured is put into the slideway 23 along the feeding tube 2, so that the PCB soft board falls into the aligned adapter grooves 7 along the feeding port 4, and is automatically inserted into the positioning component 9, the air supply component 14 is started, and the pressurized air enters the No. 1 pipe 143 through the control valve 142, and is input upward into the No. 1 cavity 8, and is input into the No. 1 hole 113 of the connecting component 11, and is input into the connecting cavity 92 through the connecting ring 112, the connecting ring 111 and the No. 2 hole 93, and is input upward into the auxiliary clamping component 12, so that the clamping tube 121 The elastic airbag belt 123 on the inner side is inflated and expands, and clamps the PCB soft board from the outside, the PCB soft board is positioned and fixed, the No. 1 tube 143 is kept closed, and the ventilation direction of the control valve 142 is switched, so that the pressurized air is input into the arc cavity 15, the heating tube 16 is started, and the regulating mechanism 21 is started, the regulating mechanism 21 drives the meshing gear 20 to rotate, and the rotating disk 6 is rotated in the processing cover 1, and the hot air heated by the heating tube 16 is blown along the purge hole 17 to the positioning component 9 and the PCB soft board in the adapter slot 7. When the rotating disk 6 rotates and drives the PCB soft board to deflect to the gap, the rotating disk 6 is rotated. When the PCB soft board is in the corresponding position of the opening 3, the power motor 10 is started to rotate the positioning assembly 9, thereby driving the PCB soft board to rotate. As the PCB soft board rotates in the adapting slot 7, the purge holes 17 on both sides continuously blow hot air toward the PCB soft board, and the PCB soft board is quickly and stably cured. When the curing is completed, the adjustment mechanism 21 is started again, and the rotating motor in the adjustment mechanism 21 drives the gear 2 to drive the gear 1 20 to rotate again, so that the rotating disk 6 continues to rotate, and the rotation of the power motor 10 is stopped. When the positioning frame 91 with the second magnetic plate 24 on both sides moves between the two sets of composite processing components 18, the two The magnetic force of the side No. 1 magnetic plate 182 causes the positioning frame 91 to automatically deflect and keep the No. 2 magnetic plates 24 on both sides facing the corresponding No. 1 magnetic plate 182. At this time, the positioning frame 91 is stably reset in the adapter slot 7. As the rotating disk 6 continues to rotate, when the adapter slot 7 is rotated down to align with the discharge port 5, the internal ventilation of the No. 1 cavity 8 by the air supply component 14 is cancelled, and the auxiliary clamping component 12 cancels the clamping and fixing. The cured PCB soft board automatically slides downward along the discharge port 5 to complete the automatic discharge. As the rotating disk 6 rotates to the upper side again and aligns with the feed port 4, the next round of curing treatment is carried out.

[0037] Firstly, by using the rotating disk 6 to switch the direction and position of the positioning component 9, and cooperating with the feed port 4, the discharge port 5 and the notch 3 at different positions on the processing cover 1, after completing the rapid positioning and sleeve connection of the PCB soft board, by switching to the notch 3 for interference-free rotation processing, and using the continuous hot air blowing on both sides of the PCB soft board in the rotating disk 6, after quickly realizing the positioning and sleeve connection of the PCB soft board, and then performing subsequent rotary hot air blowing, the upper surface of the PCB soft board is quickly heated and cured, avoiding special turning over treatment of the PCB soft board, and the actual double-sided curing is uniform and effective, ensuring that the PCB soft board is heated uniformly at all places during the curing period, realizing double-sided heating and curing, and greatly improving the actual curing heat uniformity, and the curing performance of the PCB soft board is stable.

[0038] In addition, with the rotating disk 6 constantly switching positions, and with the feed port 4, discharge port 5 and notch 3 at different positions of the processing cover 1, after the loading tube 2 automatically tilts to guide the PCB soft board to fall into the adapter groove 7, rapid positioning processing is achieved, and it is rotated to the notch 3 for rotation and uniform curing. After curing, it is rotated downward again to realize automatic processing. In fact, continuous and rapid automated processing is realized from the automatic feeding and positioning of the PCB soft board, the rotation of multi-angle heating and curing, and the downward automatic blanking. On the one hand, the processing speed is improved from all aspects, and on the other hand, the continuous action of each step is realized, which greatly shortens the curing time and provides continuous production and processing efficiency.

[0039] Embodiment 2: Before the loading process is carried out and before the PCB soft board to be cured is put in, the air supply component 14 is maintained to supply air to the arc cavity 15, and the heating tube 16 is started, so that the hot air blows the empty adapter slot 7 along the blowing hole 17, and the hot air is passed upward into the slide 23 of the loading tube 2, so that the inside of the slide 23 is preheated, and the dust and impurities inside are blown out upward to complete the self-cleaning.

[0040] Firstly, by utilizing the air supply assembly 14 to blow hot air in the arc cavity 15, in the initial state, hot air can be blown through the loading tube 2. On the one hand, preheating treatment is performed on the loading tube 2 before curing, and on the other hand, blowing and cleaning from the inside to the outside is performed, and the unloading channel of the guide PCB soft board is blown and cleaned in advance to prevent some impurities and dust from adhering to the guide PCB soft board during the heating and curing process, thereby improving the quality of the guide PCB soft board after curing.

The elastic airbag tube 183 is inflated to store the hot air, and the temperature of the heating and curing area at the notch 3 remains stable. When the adapter groove 7 rotates to the bottom and is aligned with the discharge port 5, the arc-shaped notch 25 on the rotating disk 6 is aligned with the notch 3. At this time, the hot air stored in the elastic airbag tube 183 bypasses outward through the notch 3, the arc-shaped notch 25 and the through hole opened on the outer side of the processing cover 1, and the stored hot air bypasses.

[0061] The working principle and use process of the present invention are as follows: when in use, the PCB soft board to be cured is put into the slideway 23 along the feeding tube 2, so that the PCB soft board falls into the aligned adapter grooves 7 along the feeding port 4, and is automatically inserted into the positioning component 9, the air supply component 14 is started, and the pressurized air enters the No. 1 pipe 143 through the control valve 142, and is input upward into the No. 1 cavity 8, and is input into the No. 1 hole 113 of the connecting component 11, and is input into the connecting cavity 92 through the connecting ring 112, the connecting ring 111 and the No. 2 hole 93, and is input upward into the auxiliary clamping component 12, so that the elastic airbag belt 123 on the inner side of the clamping tube 121 is inflated and expanded, and clamped from the outside. PCB soft board, the PCB soft board is positioned and fixed, the No. 1 tube 143 is kept closed, and the ventilation direction of the control valve 142 is switched so that the pressurized air is input into the arc cavity 15, the heating tube 16 is started, and the regulating mechanism 21 is started. The regulating mechanism 21 drives the meshing gear 20 to rotate, and the rotating disk 6 rotates in the processing cover 1, and the hot air heated by the heating tube 16 is blown along the purge hole 17 to the positioning component 9 and the PCB soft board in the adapter slot 7. When the rotating disk 6 rotates and drives the PCB soft board to deflect to the corresponding position of the notch 3, the power motor 10 is started to rotate the positioning component 9, thereby driving the PCB soft board to rotate. As the PCB soft board rotates in the adapter slot 7, the two sides The purge hole 17 continuously blows hot air toward the PCB soft board, and the PCB soft board solidifies quickly and stably. When the solidification is completed, the adjustment mechanism 21 is started again, and the rotating motor in the adjustment mechanism 21 drives the gear 2 to drive the gear 1 20 to rotate again, so that the rotating disk 6 continues to rotate, and the rotation of the power motor 10 is stopped. When the positioning frame 91 with the second magnetic plate 24 on both sides moves between the two groups of composite processing components 18, the magnetic force of the first magnetic plate 182 on both sides causes the positioning frame 91 to automatically deflect and keep the second magnetic plate 24 on both sides facing the corresponding first magnetic plate 182. At this time, the positioning frame 91 is stably reset in the adapter slot 7. As the rotating disk 6 continues to rotate, when the adapter slot 7 is rotated down to the discharge port, the adapter slot 7 is rotated down to the discharge port. When the opening 5 is aligned, the internal ventilation of the air supply component 14 to the first cavity 8 is cancelled, and the auxiliary clamping component 12 cancels the clamping fixation, and the cured PCB soft board automatically slides downward along the discharge port 5 to complete the automatic discharge. As the rotating disk 6 rotates to the upper side again and is aligned with the feed port 4, the next round of curing treatment is carried out; before the loading process is carried out, before the PCB soft board to be cured is put in, the air of the arc cavity 15 is maintained by the air supply component 14, and the heating tube 16 is started, so that the hot air blows the empty adapter slot 7 along the purge hole 17, and the hot air is passed upward into the slideway 23 of the feeding tube 2, so that the inside of the slideway 23 is preheated, and the internal dust and impurities are blown out upward to complete the self-cleaning;When the rotary purge is performed, the adapter groove 7, the positioning component 9 and the PCB soft board are located at the notch 3, and the hot air continuously fed is filled inside and filled into the elastic airbag tube 183 of the composite processing component 18. The elastic airbag tube 183 is inflated and expanded to store the hot air. The temperature of the heating and curing area at the notch 3 remains stable. When the adapter groove 7 rotates to the bottom and aligns with the discharge port 5, the arc-shaped notch 25 on the rotating disk 6 is aligned with the notch 3. At this time, the hot air stored in the elastic airbag tube 183 bypasses the notch 3, the arc-shaped notch 25 and the through hole opened on the outer side of the processing cover 1, and the stored hot air bypasses out. ;

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
