Description

Technical Field

[0001] This utility model relates to the field of fiberglass board technology, and in particular to an impregnation equipment for producing fiberglass boards. Background Technology

[0002] Fiberglass board, also known as FR-4 (the most common type of fiberglass board in the electronics industry), is a composite material made by impregnating fiberglass cloth with epoxy resin and other adhesives, followed by high-temperature and high-pressure thermosetting. It is commonly used as a material for PCB substrates. Fiberglass board production involves impregnating fiberglass cloth with resin to ensure thorough wetting, followed by molding and curing. During the impregnation process, tension control of the fiberglass cloth is crucial. Excessive or insufficient tension can lead to uneven impregnation, inconsistent resin content, and uneven product thickness, affecting product quality and production efficiency. Existing impregnation equipment often lacks precise tension control mechanisms, making adjustments inconvenient and prone to causing wrinkling, breakage, or resin waste in the fiberglass cloth.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-6As shown, this utility model provides an impregnation equipment for producing fiberglass boards, including a frame 1, an impregnation guide roller assembly mounted on the frame 1, an impregnation tank 3 mounted at the bottom of the frame 1, a pressure sensor 4 mounted above the impregnation tank 3, a guide rail 11 mounted at the top of the frame 1, an adjusting roller support frame 5 slidably mounted on the guide rail 11, and a tension adjusting roller assembly 6 rotatably mounted on the adjusting roller support frame 5. The tension adjusting roller assembly 6 includes a tension adjusting roller 61 rotatably mounted on one side of the adjusting roller support frame 5 and an adjusting roller drive device 62 for driving the tension adjusting roller 61 to rotate. The adjusting roller drive device 62 is mounted on the adjusting roller support frame 5. The power output end of the adjusting roller drive device 62 drives and connects to one end of the tension adjusting roller 61, and the other end of the tension adjusting roller 61 is connected to a rotating bearing 63. A bearing sliding groove 12 is provided on the inner side wall of the frame 1 along the sliding direction of the adjusting roller support frame 5. Inserted into the bearing sliding groove 12, this utility model can maintain a constant tension at a preset value by controlling the rotation speed of the pressure sensor 4 and the tension adjusting roller assembly 6 through a controller. Through the cooperation of the tension adjusting roller assembly 6 and the pressure sensor 4, the tension of the fiberglass cloth can be monitored in real time during the impregnation process, and the rotation speed of the tension adjusting roller 61 can be adjusted by the adjusting roller drive device 62, thereby accurately controlling the tension of the fiberglass cloth. This helps to ensure that the fiberglass cloth maintains uniform tension during impregnation, avoiding slack or excessive tightness, making the resin impregnation more uniform, and improving the quality consistency and mechanical properties of the fiberglass board. In addition, the adjusting roller support frame 5 is slidably set on the guide rail 11, which facilitates the adjustment of the position of the tension adjusting roller 61 according to production needs, enhancing the flexibility and adaptability of the equipment. The rotating bearing 63 is inserted into the bearing sliding groove 12, ensuring the stable operation of the tension adjusting roller 61, reducing wear, and extending the service life of the equipment.

[0022] The present invention provides a guide rail groove 111 inside the guide rail 11 and a threaded hole 51 on the top of the adjusting roller support frame 5. A fixing screw 52 is installed in the threaded hole 51, and a nut 53 is installed in the guide rail groove 111. The fixing screw 52 and the nut 53 are threadedly connected. By opening the guide rail groove 111 in the guide rail 11 and setting the fixing screw 52 and nut 53 on the adjusting roller support frame 5, the adjusting roller support frame 5 is firmly fixed and easily adjusted. After the operator easily slides the adjusting roller support frame 5 to the desired position, it is fixed by tightening the threaded connection between the fixing screw 52 and the nut 53, ensuring that the tension adjusting roller 61 is stable and does not shift during operation, thereby ensuring the accuracy and consistency of tension control.

[0023] The impregnation guide roller mechanism 2 of this utility model includes a first guide roller 21 disposed at the entrance of the impregnation tank 3, a second guide roller 22 disposed at the bottom of the impregnation tank 3, a first transition guide roller assembly 23 disposed on the frame 1, and a second transition guide roller assembly 24 disposed on the frame 1. The first guide roller 21 guides the fiberglass cloth smoothly into the impregnation tank 3, the second guide roller 22 ensures that the fiberglass cloth is fully impregnated at the bottom of the tank, and the transition guide roller assembly 23 smoothly transitions the fiberglass cloth, reducing friction and stress concentration, which helps the fiberglass cloth to run smoothly, avoids wrinkling, breakage or deviation, and improves production continuity and efficiency.

[0024] Both the first transition guide roller assembly 23 and the second transition guide roller assembly 24 of this utility model include a guide roller fixing plate 231 fixedly disposed on the inner side wall of the frame 1, a guide roller support plate 232 fixedly disposed on one side of the guide roller fixing plate 231, a transition guide roller 233 fixedly disposed between the guide roller fixing plate 231 and the guide roller support plate 232, and a rotating shaft 234 rotatably disposed between the guide roller fixing plate 231 and the guide roller support plate 232. Four fixing rods 235 are disposed between the guide rail 11 fixing plate and the guide roller support plate 232, and one side of the four fixing rods 235 is fixedly connected to the guide roller fixing plate 231. The other side of the four fixing rods 235 is threaded to the guide roller support plate 232. The fixing rods 235 connect the guide roller fixing plate 231 and the guide roller support plate 232, and the threaded connection ensures that the overall structure is firm and has good vibration resistance. The transition guide roller 233 rotates smoothly through the rotating shaft 234, which significantly reduces the running resistance of the fiberglass cloth, thereby reducing energy consumption and wear and extending the equipment life. In addition, the threaded connection between the guide roller support plate 232 and the fixing rods 235 facilitates quick disassembly and replacement, improves the maintainability and cleaning efficiency of the equipment, and is suitable for production environments where guide rollers are frequently adjusted or replaced.

[0025] The frame 1 of this invention has a connecting plate 13 on its top, and two sets of impregnation guide roller mechanisms 2 are provided, symmetrically arranged on the left and right sides of the connecting plate 13. By setting the connecting plate 13 on the top of the frame 1 and symmetrically arranging the two sets of impregnation mechanisms on the left and right sides of the connecting plate 13, dual-station or multi-station production is realized. The symmetrical design allows multiple fiberglass cloths to be processed simultaneously, greatly improving production efficiency and making it suitable for high-volume production needs. At the same time, the symmetrical arrangement helps to balance the equipment load, reduce vibration and wear, and ensure operational stability and product consistency.

[0026] The pressure sensor 4 of this invention is set as a tension roller. The tension roller not only guides and supports the fiberglass cloth, but also detects the tension change in real time through the pressure sensor 4 and feeds the data back to the control system, so as to facilitate precise control of the tension adjustment roller 61.

[0027] The impregnation tank 3 of this utility model has one side wall that is inclined from top to bottom. The inclined structure facilitates the flow and collection of resin, avoids resin accumulation or solidification at the corner of the tank, ensures that the fiberglass cloth is in uniform contact with the resin liquid surface during impregnation, and improves the consistency of impregnation.

[0028] The present invention has a glue scraper 31 fixedly installed inside the glue impregnation tank 3. Several glue scrapers 31 are arranged alternately on the left and right sides along the inclined direction of the side wall of the glue impregnation tank 3. The glue scraper 31 can effectively remove excess resin from the surface of the fiberglass cloth, control the glue layer thickness, ensure uniform glue impregnation and consistent product thickness. The alternate arrangement avoids blind spots in glue scraping, making the glue scraping effect more comprehensive and uniform, and reducing the problem of resin dripping or accumulation.

[0029] The present invention provides rounded corners 311 on one side of the two adjacent scraper blades 31. The rounded corners 311 design can reduce the contact stress between the scraper blades 31 and the fiberglass cloth, avoid scratching or damaging the surface of the fiberglass cloth, and protect the integrity and mechanical properties of the fiberglass cloth. At the same time, the rounded corners 311 structure can extend the service life of the scraper blades 31, reduce the replacement frequency due to wear, and reduce maintenance costs.

[0030] Working principle: During operation, the fiberglass cloth is first drawn out from the unwinding device or feeding device and enters the equipment body. During operation, the fiberglass cloth sequentially passes through the first transition guide roller assembly 23, the tension adjusting roller assembly 6, and the second transition guide roller assembly 24, and then enters the impregnation tank 3. At the entrance of the impregnation tank 3, the first guide roller 21 guides the fiberglass cloth downwards into the adhesive solution, passes around the second guide roller 22 at the bottom of the impregnation tank 3, and then exits upwards, thus completing sufficient impregnation. The pressure sensor 4 (in this embodiment, a tension roller) located above the impregnation tank 3 will detect the tension data of the fiberglass cloth after impregnation in real time. When the detected tension deviates from the set value, the control system (which can be a controller, etc., this is a conventional technical means) will activate the adjusting roller drive device 62 to drive the tension adjusting roller 61 to rotate or adjust its position. Since the tension adjusting roller 61 is mounted via the rotating bearing 63... Mounted on an adjusting roller support frame 5 that can move along the bearing sliding groove 12, its movement can change the wrap angle and path length of the fiberglass cloth. The operator can slide the adjusting roller support frame 5 to the desired position to adjust the tension of the entire section of cloth in real time and automatically, so that it remains stable. This effectively prevents the fiberglass cloth from breaking due to excessive tension or wrinkling and deviation due to insufficient tension, and ensures the uniformity of the adhesive impregnation. After the fiberglass cloth leaves the impregnation tank 3, excess adhesive will be attached to its surface. The cloth passes through multiple scraper blades 31 arranged alternately in the impregnation tank 3. The scraper blades 31 use their unique arrangement and rounded corner 311 design to scrape off the excess adhesive from both sides of the fiberglass cloth with less resistance, accurately control the amount of adhesive applied, and avoid damaging the fiberglass cloth. Finally, the fiberglass cloth that has been scraped and is uniformly impregnated is led out of the equipment and enters the subsequent drying and curing process.

[0031] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
