Description

Technical Field

[0001] This utility model relates to the field of fiberglass cloth production technology, and in particular to an electronic-grade fiberglass cloth fabric winding machine. Background Technology

[0002] Electronic-grade fiberglass cloth is a high-performance industrial substrate widely used in printed circuit boards (PCBs), composite materials, aerospace, and other fields. In its production process, the outer winding machine of the cloth weaving machine is a key winding device, used to evenly wind the woven fiberglass cloth onto the winding rollers for subsequent transportation, storage, or further processing.

[0003] However, existing electronic-grade fiberglass cloth fabric making machines and external winding machines have many technical problems in practical applications, especially the low efficiency of winding roller replacement, which seriously affects the overall production efficiency. In the continuous production process of electronic-grade fiberglass cloth, the winding roller needs to be replaced after it is fully wound with cloth. Traditional external winding machines usually adopt a fixed winding roller structure. Operators need to first unload the fully loaded winding roller and then install a new empty roller. The whole process involves multiple steps such as bolt disassembly and re-alignment and fixation, which takes a long time. Utility Model Content

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 6 As shown in the figure, the electronic-grade fiberglass cloth fabric winding machine proposed in this embodiment includes a base frame 1, a rotating frame device, a drive device, and two separation devices.

[0023] The base frame 1 has side plates 2 vertically installed at both ends; the rotating frame device includes a rotating shaft 6, a second servo motor 9 and two crosses 7. The two ends of the rotating shaft 6 are rotatably installed on the side plates 2 on both sides, and the two crosses 7 are respectively installed at both ends of the rotating shaft 6. The second servo motor 9 is installed on the side plate 2 and its output shaft is connected to the rotating shaft 6.

[0024] Multiple sets of limiting components are installed on both sides of the cross 7. The limiting components on both sides are set one-to-one, and there are four sets of limiting components on both sides. The limiting components include a rotating shaft 21, a second rotating cylinder 23, a second spring 24, and a limiting plate 26. The rotating shaft 21 is rotatably mounted on the cross 7. Two limiting rings 22 are arranged side by side on the rotating shaft 21. The second rotating cylinder 23 is slidably mounted on the outside of the rotating shaft 21 along the length direction of the rotating shaft 21. The inner end of the rotating shaft 21 is located in the second rotating cylinder 23 and connected to the limiting plate 26. The second spring 24 is sleeved on the rotating shaft 21. A movable ring 25 is provided on the outer periphery of the second rotating cylinder 23. Multiple take-up rollers 8 are arranged between the two cross 7. Both ends of the take-up roller 8 are connected to take-up roller shafts 81. A key 20 is provided on the take-up roller shaft 81 on one side. Keyways 231 are opened on the inner walls of the multiple second rotating cylinders 23 on the same side as the key 20.

[0025] The drive unit is mounted on the side plate 2 on one side; two separation devices are symmetrically arranged at both ends of the base frame 1. The separation device includes a mounting frame 3 connected to the base frame 1, two push plates 5 slidably mounted on the mounting frame 3, and a drive assembly for driving the two push plates 5 to move closer or further apart. The drive assembly includes a first servo motor 41 and a bidirectional lead screw 42. The bidirectional lead screw 42 is rotatably mounted on the mounting frame 3. Both push plates 5 are threadedly connected to the bidirectional lead screw 42. The first servo motor 41 is mounted on the mounting frame 3 and its output shaft is connected to the bidirectional lead screw 42.

[0026] Both side plates 2 have sliding holes 201 at their lower parts. Sliding seats 27 are slidably arranged in the sliding holes 201 on both sides. A pressure roller 12 is rotatably installed between the two sliding seats 27. A guide rod 29 is arranged in the sliding holes 201 on both sides. The guide rod 29 moves through the corresponding sliding seat 27. A third spring 28 is sleeved on the guide rod 29. With the above structure, the pressure roller 12 is pressed against the surface of the wound fabric to prevent the fabric from being too loose.

[0027] Furthermore, in this technical solution, a PLC controller 10 is installed on the side plate 2.

[0028] In this embodiment, by setting multiple sets of limiting components, the device has at least independent winding, unloading and assembly stations, and each process can be carried out synchronously, which improves work efficiency.

[0029] When assembling the take-up roller 8, the two push plates 5 on the corresponding sides are driven to move away from each other. The two push plates 5 push the two corresponding moving rings 25 outward, thereby causing the two second rotating cylinders 23 to move away from each other. At this time, the second spring 24 is compressed, placing the take-up roller 8 between the two corresponding second rotating cylinders 23. The two push plates 5 are driven to move closer together. Under the elastic force of the second spring 24, the second rotating cylinders 23 on both sides are automatically reset. At this time, the take-up roller shafts 81 at both ends of the take-up roller 8 are inserted into the second rotating cylinders 23 on both sides respectively. It should be noted that when installing the take-up roller 8, the key 20 and the keyway 231 need to be aligned.

[0030] When disassembling the take-up roller 8, simply drive the two moving rings 25 on the corresponding sides to move away from each other. At this time, the two take-up roller shafts 81 at both ends of the take-up roller 8 will move out of the second rotating cylinder 23 on both sides respectively.

[0031] Example 2

[0032] like Figure 4 and Figure 5 As shown in this embodiment, the electronic-grade fiberglass cloth fabric winding machine, compared to Embodiment 1, has a different driving device. In this embodiment, the driving device includes an electric push rod 11, a sliding frame 13, a third servo motor 14, a clamping plate 18, and an elastic telescopic rod assembly. The electric push rod 11 is mounted on a side plate 2 on one side. The sliding frame 13 is connected to the output shaft of the electric push rod 11. The third servo motor 14 is mounted on the sliding frame 13. The elastic telescopic rod assembly is mounted on the output shaft of the third servo motor 14. The clamping plate 18 is connected to the outer end of the elastic telescopic rod assembly. The elastic telescopic rod assembly includes a first rotating cylinder 15, a limiting slider 16, a movable shaft 17, and a first spring 19. The first rotating cylinder 15 is connected to the output shaft of the third servo motor 14. The movable shaft 17 movably passes through the end of the first rotating cylinder 15. The inner and outer ends of the movable shaft 17 are respectively connected to the limiting slider 16 and the locking plate 18. The limiting slider 16 is slidably installed inside the first rotating cylinder 15. The first spring 19 is installed inside the first rotating cylinder 15. A slot 211 is provided on each of the multiple rotating shafts 21 adjacent to the drive device.

[0033] In this embodiment, when the installed take-up roller 8 rotates to the bottom position, the electric push rod 11 is activated to drive the elastic telescopic rod assembly to move closer to the rotating shaft 21 on the corresponding side. If the card plate 18 is aligned with the card slot 211 at this time, the card plate 18 is inserted into the card slot 211, realizing the power connection. If the card plate 18 is not aligned with the card slot 211, the first spring 19 is in a compressed state. As the third servo motor 14 drives the card plate 18 to rotate, when the card plate 18 is aligned with the card slot 211, the card plate 18 is inserted into the card slot 211 under the elastic force of the second spring 24, realizing the power connection.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
