Description

Technical Field

[0001] The invention belongs to the technical field of PI film production and transportation, and in particular relates to a transportation device for PI film production. Background Art

[0002] PI film, also known as polyimide film, is a type of high-performance thin-film insulating material made by condensing and casting pyromellitic anhydride and diaminodiphenyl ether in a strong polar solvent and then imidizing. Due to its excellent heat resistance, moisture and heat resistance, radiation resistance and dielectric properties, it is widely used in aerospace, computers, transformers, electronic products, automobiles, atomic energy industry and other electronic and electrical fields.

[0003] The current common PI film production process mainly consists of polymerization reaction, slurry preparation, film preparation, pressing, drying and other post-processing steps. During the drying process of the PI film, corresponding conveying equipment is required to clamp, limit and move the PI film.

[0004] In the prior art, during the production and processing of PI film, winding rollers are mainly provided at both ends of the oven to clamp and move the PI film. By winding the PI film, the PI film can be moved and transported in the oven, thereby realizing the drying process of the PI film. However, when this method is used to transport the PI film, a certain length of PI film needs to be rolled up on the winding roller at the other end along the oven in advance. This not only causes a waste of a certain length of PI film, but also the convenience of clamping and moving the PI film is poor, which makes the actual application effect of the conveying equipment for PI film production poor.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0006] The object of the present invention is to provide a conveying device for PI film production, which can improve the high stability and high convenience of mobile conveying of PI film.

[0007] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

[0008] A conveying device for PI film production comprises: an oven, a clamping and conveying mechanism, a tensioning and winding mechanism, and a slitting mechanism.

[0009] The clamping and conveying mechanism is installed in the oven, and the clamping and conveying mechanism includes a pair of conveying chains. The pair of conveying chains are symmetrically arranged in the oven, and one end of the pair of conveying chains located outside the oven is meshed with a pair of driving sprockets, and the pair of driving sprockets are respectively arranged on both sides of the oven, and multiple groups of evenly distributed clamping components are fixedly installed above the pair of conveying chains.

[0010] The tensioning and winding mechanism is fixedly installed on one side of the oven, and the tensioning and winding mechanism includes a winding shaft, which is rotatably installed at the discharge port of the oven, and a winding roller is mounted on the outer side of the winding shaft. Both ends of the winding shaft are rotatably equipped with a shaft fixing seat, and an electric telescopic rod is fixedly installed below the shaft fixing seat.

[0011] The slitting mechanism is fixedly mounted above the winding shaft, and is used for slitting the PI film wound by the winding roller.

[0012] In one or more embodiments of the present invention, a pair of guide rails are fixedly installed in the oven, and the pair of conveyor chains are slidably matched with the guide rails. The guide rails play a role of limiting and guiding the conveyor chain, thereby ensuring the movement stability of the drive sprocket. At the same time, the clamping bottom plate can be supported and limited by the guide rails. A pair of drive motors are fixedly installed at the feed port of the oven, and the output shaft of the drive motor is fixedly connected to the drive sprocket. The drive motor plays a role of providing power, and the drive sprocket is driven to rotate by controlling the operation of the drive motor, thereby facilitating the drive control of the conveyor chain.

[0013] In one or more embodiments of the present invention, support sprockets are rotatably mounted on both sides of the oven, and the support sprockets mesh with the conveyor chain. The support sprockets play an auxiliary role in limiting the conveyor chain. A chain box is arranged outside the support sprocket, and the part of the conveyor chain outside the oven passes through the chain box. The part of the conveyor chain outside the oven is protected from dust by the chain box.

[0014] In one or more embodiments of the present invention, a pair of feed wheel frames are fixedly mounted at the feed inlet of the oven. The feed wheel frames play a role in assembling and limiting the feed guide wheels. A pair of feed guide wheels are rotatably mounted above each of the pair of feed wheel frames, and the pair of feed guide wheels are arranged corresponding to the feed inlet of the oven. The PI film to be processed is supported, limited, guided and transported by the cooperation of the pair of feed guide wheels.

[0015] In one or more embodiments of the present invention, a pair of discharge wheel frames are fixedly mounted at the discharge port of the oven. The discharge wheel frames play a role of assembly limit for the discharge guide wheels. A pair of discharge guide wheels are rotatably mounted above the pair of discharge wheel frames, and the discharge guide wheels are correspondingly arranged with the winding rollers. The PI film baked in the oven is discharged through the discharge guide wheels.

[0016] In one or more embodiments of the present invention, the clamping assembly includes a clamping base plate, and the clamping base plate is fixedly mounted above the conveying chain. The clamping base plate provides bottom support for the PI film to be processed. A limiting top block is fixedly mounted above the clamping base plate. The limiting top block plays the role of assembling and supporting the clamping top plate. A clamping top plate is slidably mounted on one side of the limiting top block. The PI film to be processed is clamped and limited by the mutual cooperation of the clamping top plate and the clamping base plate, so that the PI film to be processed can move synchronously with the movement of the conveying chain. The side of the clamping base plate close to the clamping top plate is fixedly mounted with a protective pad. The provision of a protective pad improves the clamping effect of the clamping base plate and the clamping top plate, and avoids damage to the PI film caused by the clamping process.

[0017] In one or more embodiments of the present invention, one end of the clamping top plate located in the limiting top block is fixedly connected to a connecting spring. The connecting spring serves to connect the clamping top plate and the clamping bottom plate, and supports and resets the clamping top plate through the contraction and reset of the connecting spring. A magnet and an adsorption electromagnet are arranged at both ends of the connecting spring, respectively. The magnet is fixedly mounted on one side of the clamping top plate close to the connecting spring, and the adsorption electromagnet is mounted below the connecting spring. The movement of the clamping top plate is controlled by the mutual attraction between the magnet and the adsorption electromagnet, so as to facilitate driving the clamping top plate to move and clamp the PI film.

[0018] In one or more embodiments of the present invention, a limit baffle is fixedly mounted on one end of the winding shaft. The limit baffle plays a role of limiting the winding process of the PI film, thereby improving the stability of the winding of the PI film. A winding motor is fixedly mounted on one side of the shaft fixing seat, and the output shaft of the winding motor is fixedly connected to the winding shaft. The winding motor plays a role of providing power, and the winding shaft is driven to rotate by controlling the operation of the winding motor, so as to wind up the dried PI film. A base frame is fixedly mounted below the electric telescopic rod, and the base frame is fixedly connected to the side wall of the oven. The base frame plays a role of assembling and fixing the electric telescopic rod.

[0019] In one or more embodiments of the present invention, the slitting mechanism includes a threaded shaft, which is rotatably mounted above the winding shaft. The threaded shaft serves to limit the threaded clamping block and to control its movement. External threads in opposite directions are provided on both sides of the threaded shaft, and threaded clamping blocks are threadedly connected on both sides of the threaded shaft. The threaded clamping block clamps and fixes the slitting blade. At the same time, a pair of threaded clamping blocks can move in opposite directions as the threaded shaft rotates under the action of internal and external threads, thereby facilitating the adjustment of the cutting spacing of the slitting blade.

[0020] In one or more embodiments of the present invention, a pair of threaded clamping blocks are fixedly mounted with slitting blades below. The side edges of the PI film rolled up outside the threaded clamping block are slid by the slitting blades. Assembly frames are rotatably mounted on both ends of the threaded shaft. The assembly frame plays a role of assembling and fixing the threaded shaft. A guide limit cover is fixedly mounted between the pair of assembly frames, and the guide limit cover slides with the threaded clamping block. The guide limit cover plays a role of protecting and guiding the threaded clamping block. An adjusting handwheel is fixedly connected to one end of the threaded shaft located outside the assembly frame. The threaded shaft is rotationally driven by controlling the rotation of the adjusting handwheel, thereby facilitating the adjustment of the slitting spacing of a pair of slitting blades.

[0021] Compared with the prior art, the present invention simplifies the process of clamping and conveying the PI film by disclosing a clamping and conveying mechanism and a tensioning and winding mechanism. At the same time, the dried PI film can be wound and slit, greatly improving the actual application effect of the conveying equipment for PI film production. BRIEF DESCRIPTION OF THE DRAWINGS

The driving motor 203 provides power, and the driving sprocket 202 is driven to rotate by controlling the operation of the driving motor 203, so as to facilitate the driving control of the conveying chain 201.

[0042] like Figure 1 As shown, both sides of the oven 1 are rotatably equipped with support sprockets 204, which mesh with the conveying chain 201. The support sprockets 204 play an auxiliary role in limiting the conveying chain 201.

[0046] like Figure 6 to Figure 7 As shown, a pair of discharge wheel frames 208 are fixedly mounted at the discharge port of the oven 1. The discharge wheel frames 208 play a role of assembling and limiting the discharge guide wheel 209.

[0047] like Figure 6 to Figure 7 As shown, a pair of discharge guide wheels 209 are rotatably mounted above the pair of discharge wheel frames 208, and the discharge guide wheels 209 are arranged corresponding to the winding roller 302. The PI film baked in the oven 1 is discharged through the discharge guide wheels 209.

[0048] like Figures 4 to 5 As shown, a pair of conveyor chains 201 are fixedly mounted with multiple sets of evenly distributed clamping components on top.

[0049] like Figures 4 to 5 As shown, the clamping assembly includes a clamping bottom plate 210, and the clamping bottom plate 210 is fixedly assembled above the conveying chain 201. The clamping bottom plate 210 supports the bottom of the PI film to be processed.

[0050] like Figures 4 to 5 As shown, a limit top block 211 is fixedly mounted on the top of the clamping bottom plate 210. The limit top block 211 plays the role of assembling and supporting the clamping top plate 212.

[0051] like Figures 4 to 5 As shown, one side of the limit top block 211 is slidably equipped with a clamping top plate 212. The clamping top plate 212 and the clamping bottom plate 210 cooperate with each other to clamp and limit the processing PI film, so that the PI film to be processed can move synchronously with the movement of the conveying chain 201.

[0052] like Figures 4 to 5As shown, the side of the clamping bottom plate 210 and the clamping top plate 212 close to each other is fixedly equipped with a protective pad 213. The protective pad 213 is provided to improve the clamping effect of the clamping bottom plate 210 and the clamping top plate 212, and avoid damage to the PI film caused by the clamping process.

[0053] like Figures 4 to 5 As shown, one end of the clamping top plate 212 located in the limiting top block 211 is fixedly connected with a connecting spring 214.

[0054] like Figures 4 to 5 As shown, a magnet 215 and an adsorption electromagnet 216 are arranged at both ends of the connection spring 214, respectively. The magnet 215 is fixedly mounted on one side of the clamping top plate 212 close to the connection spring 214, and the adsorption electromagnet 216 is mounted below the connection spring 214. The clamping top plate 212 is controlled to move by the mutual attraction between the magnet 215 and the adsorption electromagnet 216, so as to facilitate driving the clamping top plate 212 to move and clamp the PI film.

[0055] It is worth noting that the magnetism of the magnet 215 and the attraction electromagnet 216 are opposite.

[0056] like Figure 6 to Figure 7 As shown, the tensioning and winding mechanism 3 is fixedly assembled on one side of the oven 1, and the tensioning and winding mechanism 3 includes a winding shaft 301, which is rotatably assembled at the discharge port of the oven 1. The winding shaft 301 plays the role of assembling, fixing and rotating the winding roller 302.

[0057] like Figure 6 to Figure 7 As shown, a winding roller 302 is mounted on the outer side of the winding shaft 301. The PI film dried in the oven 1 is wound up by the rotation of the winding roller 302.

[0058] like Figures 6 to 9 As shown, both ends of the winding shaft 301 are rotatably provided with shaft fixing seats 303. The shaft fixing seats 303 play a role of supporting and limiting the winding shaft 301.

[0059] like Figures 6 to 9 As shown, an electric telescopic rod 304 is fixedly installed below the rotating shaft fixing seat 303. By controlling the lifting and lowering of the electric telescopic rod 304, the winding roller 302 is synchronously lifted and lowered, which not only provides convenience for the subsequent disassembly and assembly of the winding roller 302, but also provides a basis for the slitting of the PI film outside the winding roller 302.

[0060] like Figures 6 to 9As shown, one end of the winding shaft 301 is fixedly equipped with a limit baffle 305. The limit baffle 305 plays a limiting role in the winding process of the PI film, thereby improving the stability of the winding of the PI film.

[0061] like Figures 6 to 9 As shown, a winding motor 306 is fixedly mounted on one side of the shaft fixing seat 303, and the output shaft of the winding motor 306 is fixedly connected to the winding shaft 301. The winding motor 306 provides power, and the winding shaft 301 is driven to rotate by controlling the operation of the winding motor 306, so as to wind up the dried PI film.

[0062] like Figures 6 to 9 As shown, a bottom frame 307 is fixedly mounted below the electric telescopic rod 304, and the bottom frame 307 is fixedly connected to the side wall of the oven 1. The bottom frame 307 plays a role in assembling and fixing the electric telescopic rod 304.

[0063] like Figures 6 to 11 As shown, the slitting mechanism 4 is fixedly assembled above the winding shaft 301 , and the slitting mechanism 4 is used to slitting the PI film wound by the winding roller 302 .

[0064] like Figures 6 to 11 As shown, the slitting mechanism 4 includes a threaded shaft 401, which is rotatably mounted above the winding shaft 301. The threaded shaft 401 serves to limit the threaded clamping block 402 and control its movement.

[0065] Specifically, both sides of the threaded shaft 401 are provided with external threads in opposite directions, and both sides of the threaded shaft 401 are threadedly connected with threaded clamping blocks 402. The threaded clamping blocks 402 clamp and fix the slitting blade 403. At the same time, the pair of threaded clamping blocks 402 can move in opposite directions with the rotation of the threaded shaft 401 under the action of the internal and external threads, so as to facilitate the adjustment of the cutting spacing of the slitting blade 403.

[0066] like Figures 6 to 11 As shown, a pair of threaded clamping blocks 402 are fixedly provided with slitting blades 403 below. The slitting blades 403 are used to slit the side edges of the PI film rolled up outside the threaded clamping blocks 402.

[0067] like Figures 6 to 11 As shown, both ends of the threaded shaft 401 are rotatably mounted with mounting brackets 404. The mounting brackets 404 play a role in assembling and fixing the threaded shaft 401.

[0068] like Figures 6 to 11As shown, a guide limit cover 405 is fixedly mounted between a pair of assembly frames 404, and the guide limit cover 405 is slidably matched with the thread clamping block 402. The guide limit cover 405 plays a role of protecting and guiding the thread clamping block 402.

[0069] like Figures 6 to 11 As shown, one end of the threaded shaft 401 outside the assembly frame 404 is fixedly connected with an adjusting hand wheel 406. The threaded shaft 401 is driven to rotate by controlling the rotation of the adjusting hand wheel 406, so as to facilitate the adjustment of the slitting interval of a pair of slitting blades 403.

[0070] When in use, the PI film to be processed is placed between a pair of feed guide wheels 207, and the feed guide wheels 207 are used to support and guide the PI film to be processed. Subsequently, the PI film to be processed can be placed between a pair of conveyor chains 201 by pulling, specifically between the clamping bottom plate 210 and the limiting top block 211. Subsequently, the adsorption electromagnet 216 can be controlled to be charged so that the adsorption electromagnet 216 has magnetic properties, so that the magnet 215 drives the clamping top plate 212 to descend under the principle of opposites attracting each other, thereby clamping the PI film to be processed through the cooperation between the clamping top plate 212 and the clamping bottom plate 210.

[0071] Then, a pair of driving sprockets 202 can be driven to rotate by controlling the operation of a pair of driving motors 203, so that a pair of conveying chains 201 can drive the clamping base plate 210 to move under the meshing action of the driving sprockets 202, and the PI film to be processed clamped between the clamping base plate 210 and the clamping top plate 212 can be moved and transported to the oven 1 by controlling the movement of the clamping base plate 210, and the PI film to be processed can be dried and processed by the oven 1.

[0072] The PI film after drying can be moved to the winding roller 302 under the guidance of the discharge guide wheel 209, and the winding shaft 301 can be driven to rotate by controlling the operation of the winding motor 306, so that the winding roller 302 rotates synchronously with the rotation of the winding shaft 301, and the dried PI film is wound up by the rotation of the winding roller 302.

[0073] When the PI film is rolled up, the winding roller 302 can be synchronously raised and lowered by controlling the electric telescopic rod 304 to rise and fall, and the sides of the rotating PI film coil can be cut by a pair of slitting blades 403. After the slitting is completed, the electric telescopic rod 304 can be synchronously controlled to descend to unload the PI film coil rolled on the outside of the winding roller 302.

[0074] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0075] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
