Description

Technical Field

[0001] This utility model relates to the field of electronic cloth production technology, specifically an automatic winding device for electronic cloth production. Background Technology

[0002] Electronic cloth is a high-performance substrate used in the electronics industry. It is usually woven from extremely fine glass fibers and undergoes special treatment. It has characteristics such as dimensional stability, high temperature resistance, and good insulation. It is widely used in printed circuit boards, chip packaging, and composite materials. Its thickness ranges from ultra-thin tens of micrometers to hundreds of micrometers. It is extremely sensitive to the cleanliness, tension, temperature, and humidity of the production environment. The winding device is the core equipment in the production of electronic cloth, and its performance directly determines the quality of the final roll.

[0003] For example, patent CN219217002U discloses an electronic fabric winding device with anti-deviation function, including a crossbar, an I-shaped winding shaft installed on the side wall of one end of the crossbar, and a deviation correction component. A bracket is vertically fixed at the bottom of the crossbar. The deviation correction component includes an air storage box and an air guide seat. An L-shaped block is fixed at the bottom of the air storage box and is fixedly connected to the side wall of the bracket. An air guide pipe connected to the air outlet of an external blower is connected to the side wall of the air storage box. Air guide covers are connected to the front and rear sides of the upper end of the air storage box, and air outlets are opened on the opposite side walls of the two air guide covers. The air guide seat is fixed on the upper end of the air storage box and is located between the two air guide covers. The front and rear side walls of the air guide seat are provided with an inclined air guide surface that guides the air guide seat downwards to the center. This solves the problem that the electronic fabric is prone to deviation due to its soft texture and loose state. It also avoids the electronic fabric from folding and being damaged after winding. However, there are still areas for improvement.

[0004] Firstly, high-speed airflow can easily cause the electronic fabric to vibrate or flutter at high frequencies, interfering with the stability of tension control and potentially leading to uneven winding or hidden wrinkles.

[0005] Secondly, if the airflow uniformity is not properly controlled, it may cause uneven force on both sides of the fabric, forming wavy edges and affecting the subsequent winding quality. Utility Model Content

[0006] This invention provides an automatic winding device for electronic fabric production to address the problems that wind-driven wrinkle removal may cause vibration of the electronic fabric and the formation of wavy edges that affect the winding effect.

[0007] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0008] This utility model provides an automatic winding device for the production of electronic cloth, including a winding device body for winding electronic cloth, wherein a plurality of rotating rods are installed at the front end of the winding device body, and the output end of a drive motor is fixedly installed at the end of the rotating rods;

[0009] The rotating rod is hollow, and two expansion films are symmetrically fixed on the outside. The expansion films are spirally installed on the outside of the rotating rod, and a spiral groove that matches the expansion films is opened through the outside of the rotating rod.

[0010] The rotating rods are divided into multiple groups, each with a different coefficient of friction for the outer expansion film, to meet different production needs.

[0011] Furthermore, a mounting frame is fixedly installed on the outside of the winding device body, and a flat plate is fixedly installed on the outside of the mounting frame. Multiple receiving slots are opened through the middle of the flat plate, a rotating rod is rotatably installed inside the receiving slots, and a drive motor is fixedly installed on the outside of the flat plate.

[0012] Furthermore, an inflation tube is rotatably mounted on the end of the rotating rod away from the drive motor. The inflation tube is fixedly mounted on the outside of the flat plate, and an inflation valve is connected to the end of the inflation tube. The inflation valve is connected to an external air supply device.

[0013] Furthermore, a pressure detection mechanism body is fixedly installed on the outside of the inflation tube.

[0014] Furthermore, an exhaust valve is fixedly installed on the outside of the inflation tube.

[0015] Furthermore, a perforated plate is fixedly installed on the outer side of the mounting frame, a negative pressure cover is fixedly installed at the bottom of the perforated plate, and a negative pressure mechanism body is fixedly installed at the bottom of the negative pressure cover. The negative pressure mechanism body is fixedly installed on the outer side of the perforated plate.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] The expansion film inflates and comes into contact with the passing electronic cloth. The spiral expansion film rotates and gives the electronic cloth tension from the center outward, making the electronic cloth flat. Compared with the smoothing by wind, the vibration amplitude and frequency of the electronic cloth are reduced in this way, and the movement is stable, which is beneficial to the subsequent winding. Moreover, the expansion film is elastic, which reduces the possibility of friction damage to the electronic cloth.

[0019] Staff can select the corresponding rotating rod and expansion film according to the different thicknesses of electronic cloth. The expansion film with a larger coefficient of friction can provide greater tension for the electronic cloth, which is suitable for thicker electronic cloth, making the application range of this equipment wider.

[0020] After the smoothed electronic cloth passes through the perforated plate, the negative pressure mechanism is activated, generating negative pressure at the bottom of the perforated plate. This allows the electronic cloth to adhere to its top, essentially eliminating shaking and preventing wrinkles from forming again, resulting in better subsequent winding. Attached Figure Description

[0027] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0028] like Figure 1 , Figure 3 As shown, an automatic winding device for electronic cloth production includes a winding device body 1 for winding electronic cloth. A plurality of rotating rods 9 are installed at the front end of the winding device body 1, and the output end of a drive motor 7 is fixedly installed at the end of the rotating rods 9.

[0029] The rotating rod 9 is hollow, and two expansion films 10 are symmetrically fixed on its outer side. The expansion films 10 are spirally installed on the outer side of the rotating rod 9, and a spiral through groove that cooperates with the expansion films 10 is opened through the outer side of the rotating rod 9.

[0030] Specifically, such as Figure 1 As shown, a mounting frame 2 is fixedly installed on the outside of the main body 1 of the winding device, and a flat plate 6 is fixedly installed on the outside of the mounting frame 2. Multiple receiving slots 8 are opened through the middle of the flat plate 6. A rotating rod 9 is rotatably installed inside the receiving slots 8. The top height of the rotating rod 9 is lower than the top height of the flat plate 6. The idle rotating rod 9 and the expansion film 10 do not contact the electronic cloth. The drive motor 7 is fixedly installed on the outside of the flat plate 6.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, an inflation tube 11 is rotatably mounted on the end of the rotating rod 9 away from the drive motor 7. The inflation tube 11 is fixedly mounted on the outside of the flat plate 6. An inflation valve 14 is connected to the end of the inflation tube 11. When inflation tube 11 is inflated, the inflation valve 14 is opened and connected to an external air supply device.

[0032] Specifically, such as Figure 4 As shown, a pressure detection mechanism body 12 is fixedly installed on the outside of the inflation pipe 11, and the pressure detection mechanism body 12 is electrically connected to an external air supply device.

[0033] Specifically, such as Figure 4 As shown, an exhaust valve 13 is fixedly installed on the outside of the inflation tube 11. When it is necessary to vent, the staff opens the exhaust valve 13 to reset the expansion film 10.

[0034] In this embodiment, the external air supply device inflates the rotating rod 9 through the inflation valve 14 and inflation pipe 11. The air pressure detection mechanism body 12 detects the internal air pressure of the rotating rod 9, causing the expansion film 10 to expand until the air pressure detection mechanism body 12 detects that the pressure has reached the set value. The external air supply device stops inflating and comes into contact with the passing electronic cloth. The drive motor 7 drives the rotating rod 9 and the expansion film 10 to rotate. The threaded expansion film 10 gives the electronic cloth tension from the center outward, making the electronic cloth flat. Compared with smoothing by wind, the vibration amplitude and frequency of the electronic cloth are reduced in this way, and the movement is stable, which is beneficial for subsequent winding. Moreover, the expansion film 10 is elastic, which reduces the possibility of friction damage to the electronic cloth.

[0035] Specifically, such as Figure 3 As shown, the rotating rod 9 is divided into multiple groups, and the friction coefficient of the expansion film 10 on its outer side is different to meet different production needs.

[0036] In this embodiment, the operator can select the corresponding rotating rod 9 and expansion film 10 according to the different thicknesses of the electronic cloth. The expansion film 10 with a larger coefficient of friction can provide greater tension for the electronic cloth, which is suitable for thicker electronic cloths, making the application range of this device wider.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, a perforated plate 3 is fixedly installed on the outside of the mounting bracket 2, and a negative pressure cover 4 is fixedly installed on the bottom of the perforated plate 3 to seal the bottom of the perforated plate 3. A negative pressure mechanism body 5 is fixedly installed at the bottom of the negative pressure cover 4 to generate negative pressure at the bottom of the perforated plate 3. The negative pressure mechanism body 5 is fixedly installed on the outside of the perforated plate 3.

[0038] In this embodiment, after the smoothed electronic cloth passes through the perforated plate 3, the negative pressure mechanism body 5 is activated, and negative pressure is generated at the bottom of the perforated plate 3, so that the passing electronic cloth can adhere to its top, basically eliminating shaking and preventing wrinkles from forming again, resulting in better subsequent winding effect.

[0039] Specific work steps

[0040] An external air supply device inflates the rotating rod 9 through the inflation valve 14 and inflation pipe 11. The air pressure detection mechanism body 12 detects the internal air pressure of the rotating rod 9, causing the expansion film 10 to expand. When the air pressure detection mechanism body 12 detects that the pressure has reached the set value, the external air supply device stops inflating and comes into contact with the passing electronic cloth. The drive motor 7 drives the rotating rod 9 and the expansion film 10 to rotate. The threaded expansion film 10 gives the electronic cloth tension from the center outward, making the electronic cloth flat. Compared with smoothing by wind, the vibration amplitude and frequency of the electronic cloth are reduced in this way, and the movement is stable, which is beneficial to subsequent winding. Moreover, the expansion film 10 is elastic, which reduces the possibility of friction damage to the electronic cloth.

[0041] The operator can select the corresponding rotating rod 9 and expansion film 10 according to the different thicknesses of the electronic cloth. The expansion film 10 with a larger coefficient of friction can provide greater tension for the electronic cloth, which is suitable for thicker electronic cloth, making the application range of this equipment wider.

[0042] After the smoothed electronic cloth passes through the perforated plate 3, the negative pressure mechanism body 5 is activated, and negative pressure is generated at the bottom of the perforated plate 3, so that the electronic cloth can adhere to its top, basically eliminating shaking and preventing wrinkles from forming again, resulting in better subsequent winding effect.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
