It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0044] Embodiment 1: According to the attached Figure 1 To Attachment Figure 4 As shown, a polytetrafluoroethylene glass fiber cloth composite board production equipment is used to process and produce layered products composed of glass fiber cloth, PFA film and PTFE coil, including a composite machine 100, the composite machine 100 includes a machine body 101, one end of the machine body 101 is provided with a first feeding roller 102, a second feeding roller 103 and a third feeding roller 104 from top to bottom, the first feeding roller 102 is wound with glass fiber cloth, the second feeding roller 103 is wound with PFA film, and the third feeding roller 104 is wound with PTFE coil. When the first feeding roller 102, the second feeding roller 103 and the third feeding roller 104 are unwinding, the glass fiber cloth, PFA film and PTFE coil are conveyed.

[0045] The other end of the machine body 101 is provided with a winding device 108, and one end of the glass fiber cloth, PFA film and PTFE coil away from the first feeding roller 102, the second feeding roller 103 and the third feeding roller 104 is connected to the winding device 108. When the winding device is working, the processed glass fiber cloth, PFA film and PTFE coil are wound up.

[0046] Specifically, the first power wheel 1051 and the first driven wheel 1061 are connected to the bearing in the body 101, and the first servo motor 1071 is also installed on the body 101, and the output shaft of the first servo motor 1071 is fixedly connected to the first power wheel 1051. When the first servo motor 1071 is driven to rotate, the first servo motor 1071 drives the first power wheel 1051 to rotate.

[0047] A second power wheel 1052 and a second driven wheel 1062 are connected in the machine body 101 through bearings, and a second servo motor 1072 is also installed on the machine body 101, and the output shaft of the second servo motor 1072 is fixedly connected to the second power wheel 1052. When the second servo motor 1072 is driven to rotate, the second servo motor 1072 drives the second power wheel 1052 to rotate.

[0048] It should be noted here that a constant tension meter is installed on the second feeding roller 103 and the second power wheel 1052, and the constant tension meter is used to monitor the tension between the second feeding roller 103 and the second power wheel 1052 in real time. A torque measuring meter is installed on the second driven wheel 1062, and the torque measuring meter is used to measure the torque of the glass fiber cloth, PFA film and PTFE coil during the transportation process.

[0049] The same is that the layered product passes through the first power wheel 1051 and the first driven wheel 1061 and the second power wheel 1052 and the second driven wheel 1062, so as to transport the layered product and control the balance between the tension and torque of the layered product.

[0050] In addition, an infrared temperature controller 109 is installed on the machine body 101, a heating roller 110 is provided between the first driven wheel 1061 and the second driven wheel 1062, and a first connecting shaft 111 is installed on the heating roller 110, and pressure rollers 112 are provided on both sides of the heating roller 110 close to the first driving wheel and the second driving wheel, and the bearings of the pressure rollers 112 are connected to the inner wall of the machine body 101. The layered product is located between the heating roller 110 and the pressure roller 112, and the layered product can be heated by the heating roller 110, and the heating temperature can be controlled in real time by the infrared temperature controller 109 to improve the heating effect of the layered product.

[0051] In summary, when the glass fiber cloth, PFA film and PTFE coil are processed into layered products, the first feeding roller 102, the second feeding roller 103 and the third feeding roller 104 feed the glass fiber cloth, PFA film and PTFE coil, so that the glass fiber cloth, PFA film and PTFE coil pass between the first power wheel 1051 and the first driven wheel 1061, then enter between the heating roller 110 and the pressure roller 112, and then pass between the second power wheel 1052 and the second driven wheel 1062, and the processed layered product is wound by the winding device 108.

[0052] During the processing, the temperature and tension of the PFA film are monitored in real time through the setting of the tension constant instrument and the infrared temperature controller 109, and the torque of the glass fiber cloth, PFA film and PTFE coil is monitored in real time through the torque measuring instrument, so that the glass fiber cloth, PFA film and PTFE coil are processed into layered products.

[0053] It should be noted here that by adding a PFA film as an adhesive layer between the PTFE coil and the glass fiber cloth, a strong bond between the PTFE coil and the glass fiber cloth is achieved to prepare a three-layer composite board combining the PTFE coil, the PFA film and the glass fiber cloth. This layered product meets the requirement of easy bonding of the metal can body, and the PTFE coil has not been corroded, and has better anti-permeability and long-term use. At the same time, the layered product is produced in a clean room throughout the process, which can meet the requirements of semiconductors.

[0054] At the same time, the composite board disclosed in the first embodiment solves the technical problem that the sodium bonding process of the tetrafluoroethylene board is complicated, dangerous, and easy to cause environmental pollution. The composite board does not need sodium treatment, and by adding glass fiber cloth, it can be firmly combined with the adhesive and is easy to paste.

[0055] In addition, the problem that it is difficult to directly combine the PTFE coil and the glass fiber cloth is solved. The composite board disclosed in the first embodiment uses a soluble PFA film material added in the middle as an adhesive for the two, which is both high temperature resistant and corrosion-resistant, and the PFA film has a high bonding strength with the PTFE coil and the glass fiber cloth.

[0056] Secondly, by adding glass fiber cloth, the composite board can not only be firmly combined with the adhesive to be more resistant to high temperatures, but also increase the plastic strength of the PTFE coil itself, which is more advantageous for use in high-temperature negative pressure.

[0057] According to the attached Figure 4 As shown, in order to avoid the adhesion of dust caused by static electricity during the production and processing of the glass fiber cloth, PFA film and PTFE roll, which may cause bubbles to appear when the glass fiber cloth, PFA film and PTFE roll are bonded, and to reduce the influence of dust on the processing of the composite board, in this embodiment, a dust suction mechanism 200 is provided between the glass fiber cloth, PFA film and PTFE roll to remove dust, fibers and other tiny particles and improve product quality.

[0058] Specifically, according to the attached Figure 5 and attached Fig. 9 As shown, the dust collection mechanism 200 includes a dust collection tube 201 arranged between the glass fiber cloth, the PFA film and the PTFE roll plate, and a baffle plate 202 is provided on the side away from the dust collection tube 201, two sets of side panels 203 are provided inside the body 101, and the side of the side panels 203 that are close to each other are fixedly connected to the dust collection tube 201 and the baffle plate 202, and a connecting frame 204 is installed on the side away from the side panels 203, and the connecting frame 204 is fixedly connected to the inner wall of the body 101.

[0059] It should be understood here that the dust suction pipe 201 is located between the glass fiber cloth, the PFA film and the PTFE roll, and is used to remove dust adsorbed between the glass fiber cloth and the PFA film, and between the PFA film and the PTFE roll, thereby avoiding the generation of bubbles or bulging between the glass fiber cloth and the PTFE roll when the PFA film is used to bond the glass fiber cloth and the PTFE roll, thereby improving product quality.

[0060] Among them, a first contact surface 11 is provided on the side where the dust suction pipe 201 is close to each other, a second contact surface 12 is provided on the side where the dust suction pipe 201 is close to the first power wheel 1051 and the first driven wheel 1061, and a third contact surface 13 is provided on the side where the dust suction pipe 201 is away from each other, and the third contact surface 13 is inclined; through the setting of the first contact surface 11, the second contact surface 12 and the third contact surface 13, the contact area between the dust suction pipe 201 and the glass fiber cloth, PFA film and PTFE roll plate is increased.

[0061] Furthermore, the dust remaining on the outer surface of the glass fiber cloth, the PFA film and the PTFE roll can be removed by the first contact surface 11 and the third contact surface 13. Secondly, by setting the second contact surface 12, suction can be performed at the angle formed by the glass fiber cloth, the PFA film and the PTFE roll when entering the first power wheel 1051 and the first driven wheel 1061, thereby further removing the dust on the glass fiber cloth, the PFA film and the PTFE roll, improving product quality and avoiding the generation of bubbles.

[0062] It should be noted that a plurality of through holes 205 are provided on the first contact surface 11, the second contact surface 12 and the third contact surface 13. The through holes 205 are provided to facilitate the removal of dust adsorbed on the surfaces of the glass fiber cloth, the PFA film and the PTFE coil.

[0063] In addition, a first connecting pipe 206 is installed on the side panel 203, and the first connecting pipe 206 is arranged in a Y-shaped structure. The first connecting pipe 206 is connected to the inside of the two groups of dust suction pipes 201. A fan 207 is also installed on the connecting frame 204, and the suction end of the fan 207 is connected to the first connecting pipe 206.

[0064] When the fan 207 is driven to work, the fan 207 draws out the air in the dust suction pipe 201, so that negative pressure is formed in the dust suction pipe 201, and through the through hole 205, the dust on the surface of the glass fiber cloth, the PFA film and the PTFE roll plate is sucked to remove the dust;

[0065] When removing dust, through the setting of the second contact surface 12, suction can be performed at the angle formed by the glass fiber cloth, PFA film and PTFE roll when they enter the first power wheel 1051 and the first driven wheel 1061, so as to further remove the dust on the glass fiber cloth, PFA film and PTFE roll.

[0066] Furthermore, guide rollers 208 are provided on both the upper and lower sides of the glass fiber cloth and the PTFE roll, and the guide rollers 208 are respectively connected to the bearings of the dust suction pipe 201 and the shielding plate 202. The provision of the guide rollers 208 facilitates the transportation and protection of the glass fiber cloth and the PTFE roll, avoids friction with the corners of the dust suction pipe 201 and the shielding plate 202, and protects the glass fiber cloth and the PTFE roll.

[0067] According to the attached Figure 3 and attached Figure 4 As shown, in order to improve the flatness of the composite board and avoid problems such as wrinkles and bubbles generated during hot pressing between the glass fiber cloth, PFA film and PTFE coil, which leads to an uneven surface of the composite board, in this embodiment, a circulating mechanism 300 is provided on the heating roller 110, which is used to smooth the composite board material passing over the heating roller 110 to improve the product quality of the composite board.

[0068] Specifically, according to the attached Figure 6 and attached Figure 7 As shown, the cyclic mechanism 300 includes a guide rod 301 mounted on the inner wall of the machine body 101, and a guide sleeve 302 is slidably connected to the guide rod 301, a connecting plate 303 is mounted on the guide sleeve 302, and a first push plate 304 is mounted on the connecting plate 303. The first push plate 304 is used to smooth the composite plate material passing over the heating roller 110, thereby eliminating problems such as bubbles and wrinkles.

[0069] It should be noted here that a clearance space is provided between the two first push plates 304. In order to eliminate the problem that some materials may not be able to be smoothed due to the reserved clearance space, in the present embodiment, a second push plate 305 is provided on the side close to the first push plates 304, and the second push plate 305 is used to smooth part of the composite plate material between the two first push plates 304.

[0070] In addition, both sides of the first push plate 304 are slidably connected to the limit rod 306, and the limit rod 306 is installed on the second push plate 305. The limit rod 306 is also provided with a first spring 307, and the two ends of the first spring 307 are respectively installed on the first push plate 304 and the second push plate 305. Through the setting of the limit rod 306 and the first spring 307, the second push plate 305 is facilitated to move, thereby avoiding the problem of displacement deviation of the first push plate 304 when moving. Through the elastic connection of the first spring 307, the second push plate 305 is facilitated to move, thereby improving the flexibility of the equipment.

[0071] Furthermore, a sliding sleeve 308 is provided above the guide sleeve 302, and a sliding rod 3081 is slidably connected inside the sliding sleeve 308, and the sliding rod 3081 is installed on the guide sleeve 302. The sliding sleeve 308 is rotatably connected to the rotating shaft 309 through a rotating shaft, and a rotating sleeve 310 is slidably connected to the rotating shaft 309, and a second connecting shaft 311 is installed on the rotating sleeve 310. A fixing frame 312 is installed inside the machine body 101, and the fixing frame 312 and the second connecting shaft 311 are rotatably connected through a bearing. In addition, a second spring 315 is provided on the rotating shaft 309, and the two ends of the second spring 315 are fixedly connected to the rotating shaft 309 and the rotating sleeve 310 respectively.

[0072] Among them, according to the attached Figure 6 As shown, the internal bearing of the body 101 is connected to a transmission shaft 313, and bevel gears 314 are installed on the transmission shaft 313 and the second connecting shaft 311. The two sets of bevel gears 314 are meshingly connected, and the output shaft of the first servo motor 1071 is connected to the transmission shaft 313 through a pulley transmission mechanism 316.

[0073] When the first servo motor 1071 is driven to rotate, the transmission shaft 313 is driven to rotate synchronously through the pulley transmission mechanism 316, and the second connecting shaft 311 is driven to rotate through the meshing connection of the bevel gear 314, so as to drive the rotating sleeve 310 to rotate synchronously. When the rotating sleeve 310 rotates synchronously, the rotating sleeve 310 drives the rotating shaft 309 to rotate, so that the rotating shaft 309 rotates in a circle with the center of the second connecting shaft 311 as the center. Under the action of the rotating shaft connection, the rotating shaft 309 drives the sliding sleeve 308 to move, so that the sliding rod 3081 moves synchronously under the drive of the rotating shaft 309. At the same time, the guide sleeve 302 is slidably connected to the outside of the guide rod 301 to drive the connecting plate 303 to move synchronously.

[0074] In summary, during the rotation of the rotating shaft 309, in order to perform motion compensation for the process of converting the rotational motion into linear reciprocating motion, a traction force is provided to the rotating shaft 309 through the elastic connection of the second spring 315, so that when the rotating shaft 309 rotates, the sliding connection between the rotating shaft 309 and the rotating sleeve 310, as well as the elastic connection of the second spring 315, is used to perform motion compensation for the motion deviation generated during the rotation.

[0075] It should be additionally explained here that a first air flow channel is opened inside the first push plate 304, and a second air flow channel is opened inside the second push plate 305. The first air flow channel and the second air flow channel are used to store heat source gas, so as to facilitate heating of the composite plate material on the heating roller 110 while smoothing it, thereby avoiding a huge temperature difference between the upper surface of the composite plate material and the contact surface of the heating roller 110, which affects the heating effect of the composite plate material.

[0076] Furthermore, according to the attached Figure 7 and attached Figure 8 As shown, a second connecting pipe 3031 is installed on the connecting plate 303, and the second connecting pipe 3031 is connected to the inside of the first airflow channel. A first hose 3032 is also installed on the second connecting pipe 3031, and one end of the first hose 3032 away from the second connecting pipe 3031 is installed on the second pushing plate 305, and the first hose 3032 is connected to the inside of the second airflow channel. The second connecting pipe 3031 and the first hose 3032 are arranged to facilitate heating operations inside the first airflow channel and the second airflow channel.

An annular groove is opened on the first connecting shaft 111, and the annular groove and the annular slider 402 are slidably connected. The connecting seat 401 is installed on the body 101.

[0080] Furthermore, a heat exchange tube 403 is installed on the connecting seat 401, and the heat exchange tube 403 is arranged in a U-shaped structure. A heat exchange chamber for accommodating the heat exchange tube 403 is opened in the heating roller 110, so that the airflow discharged from the fan 207 in the heat exchange tube 403 is heated by the residual heat inside the heat exchange chamber, and the heated airflow is discharged through the first air hole 3041 and the second air hole 3051, thereby reducing the upper and lower temperature differences of the glass fiber cloth, PFA film and PTFE coil.

[0081] Among them, according to the attached Fig. 9 As shown, two groups of third connecting tubes 404 are installed on the connecting seat 401, and the third connecting tubes 404 are respectively connected to the two ends of the heat exchange tube 403, the air outlet end of the fan 207 is connected to one group of the third connecting tubes 404 through a second hose 405, and the second connecting tube 3031 and another group of the third connecting tubes 404 are connected through a third hose 406.

[0082] When the airflow is discharged from the air outlet of the fan 207, the airflow enters the heat exchange tube 403 through the second hose 405, and is heated by the heat exchange chamber, and then discharged into the first airflow channel and the second airflow channel through the third hose 406, and the first push plate 304 and the second push plate 305 are heated, so that the first push plate 304 and the second push plate 305 can heat the glass fiber cloth, PFA film and PTFE roll plate while smoothing the glass fiber cloth, PFA film and PTFE roll plate, thereby reducing the upper and lower temperature difference of the glass fiber cloth, PFA film and PTFE roll plate, and improving product quality.

[0086] The first feeding roll 102, the second feeding roll 103 and the third feeding roll 104 wound with the glass fiber cloth, the PFA film and the PTFE roll are placed on the compounding machine 100;

[0087] The glass fiber cloth, PFA film and PTFE roll plate are connected to the winding device 108 through the dust collecting mechanism 200, the first power wheel 1051, the first driven wheel 1061, the circulating mechanism 300, the second power wheel 1052 and the second driven wheel 1062;

[0088] Step 2: dust removal of materials;

[0089] The dust adsorbed between the glass fiber cloth and the PFA film, and between the PFA film and the PTFE roll plate is removed by the dust collecting mechanism 200, thereby preventing bubbles from being generated between the glass fiber cloth and the PTFE roll plate when the glass fiber cloth and the PTFE roll plate are bonded by the PFA film.

[0090] Step 3: Smooth the material;

[0091] The composite plate material passing over the heating roller 110 is smoothed by the circulating mechanism 300, thereby eliminating bubbles and wrinkles;

[0092] Step 4: Heating the materials;

[0093] While the glass fiber cloth, PFA film and PTFE roll are smoothed by the circulation mechanism 300, the glass fiber cloth, PFA film and PTFE roll can also be heated by the heat exchange mechanism 400 to reduce the upper and lower temperature difference of the glass fiber cloth, PFA film and PTFE roll to avoid expansion or contraction of the PFA film.
