[0001] The present invention relates to the technical field of running shoe carbon plate production, and more particularly to a preparation process for mass production of running shoe carbon plates. Background Art

[0002] With the continuous progress of sports equipment technology, running shoes, as essential equipment for professional athletes and fitness enthusiasts, have increasingly high performance requirements.

[0003] As an important component of running shoes, the carbon fiber plate has characteristics such as light weight, high strength, and good anti-torsion performance, which are crucial for improving the overall performance and comfort of running shoes.

[0004] At present, during the molding process of existing running shoe carbon fiber plates, due to the imperfect molding process, bubbles may be generated inside the product, affecting the appearance quality of the product, and further reducing its mechanical properties and durability, resulting in a high defective product rate of the product, thereby increasing production costs, extending the production cycle, and being unable to meet production requirements.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Invention

[0006] In view of this, in view of the deficiencies existing in the prior art, the main purpose of the present invention is to provide a preparation process for mass production of running shoe carbon plates.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0010] S2. Cut the yarn, cut the carbon fiber prepreg through a cutting device, and perform cutting processing according to the actual required cutting angle and size to obtain angled yarn;

[0011] S3. Pre-stack the yarn, pre-stack two pieces of angled yarn distributed mirror-image to obtain pre-stacked yarn, and the angles of the two pieces of angled yarn are mirror-shaped and are pasted together. At the same time, exhaust treatment is required when the two pieces of angled yarn are stacked;

[0012] S4. Cut the shape, cut the pre-stacked yarn through a cutting device, and perform cutting processing according to the actual required processing shape to obtain a pre-shaped semi-finished product;

[0013] S5. Pre-shape, stack the pre-shaped semi-finished product according to the actual required layered structure of the product to obtain a pre-shaped processed material;

[0014] S6. Upper mold: The forming mold is transported to the operating station through the mold transfer line, and the staff at the operating station puts the pre-shaped processing material into the forming mold.

[0015] S7. Vacuum pumping: The forming mold with the processing material is placed into a vacuum bag, and all the air in the vacuum bag is pumped out by a vacuum pumping device.

[0016] S8. Hot press forming: The vacuum bag containing the forming mold is placed on the movable frame, and the movable frame is pushed into the autoclave by using a pushing device. The temperature and pressure are adjusted according to the corresponding resin to be produced, and then the forming device is hot press formed by the autoclave.

[0017] S9. Demolding: The autoclave is vented. After safety, the movable frame is taken out by using a pushing device. After the mold cools down, the forming mold is demolded to obtain the demolded finished product.

[0018] S10. Grinding: According to the production requirements of the product, the periphery of the demolded finished product is ground by a grinding device.

[0019] S11. Sandblasting: Emery is sprayed on the surface of the product to make its surface uneven, so as to improve the adhesion between the product and the midsole in the follow-up.

[0020] S12. Weighing: The sandblasted finished product is placed on a weighing device for weighing detection, and the defective products that do not meet the product quality requirements are selected.

[0021] S13. Metal detection: The qualified finished product after weighing is put into a metal detector for metal detection, and the defective products with metal components inside the finished product are selected.

[0022] S14. Packaging: According to the packaging requirements of the product, the qualified finished product after detection is packaged.

[0023] As a further elaboration, in step S3, the angle yarn is flattened by a flattening jig to complete the first exhaust of the angle yarn; then the pre-laminated yarn after lamination is secondarily exhausted by an exhaust device to discharge the air inside the pre-laminated yarn layers, so as to ensure the rigidity of the product.

[0024] As a further elaboration, in step S4, the pre-laminated yarn is cut into patches corresponding to different parts by a cutting device, and the different parts include the half sole, the heel, the arch, etc., so as to facilitate the subsequent gluing connection of the patches to the corresponding strengthening positions of the pre-shaped semi-finished product.

[0025] As a further elaboration, in step S5, the preformed semi-finished products are laminated by a preforming jig. When laminating, start pasting from a corner of the preformed semi-finished product and gradually push the preformed semi-finished product to complete the pasting of the processing material.

[0026] As a further elaboration, in step S5, it also includes a refrigeration treatment, which is used to put the preformed processing material into a cold storage for refrigeration to ensure that the properties of the preformed processing material do not undergo chemical reactions due to the normal temperature environment.

[0027] As a further elaboration, in step S6, the processing material is first placed at one end of the forming mold, and then gradually pushed to the other end of the forming mold to ensure the processing quality of the product; and according to the structural shape of the product, a compaction jig is used to press the processing material tightly onto the forming mold; meanwhile, after the upper mold is installed, a release cloth is placed flat on the surface of the processing material to facilitate the demolding of the subsequent finished product.

[0028] As a further elaboration, in step S7, after vacuum pumping, the surface of the vacuum bag and the processing material should be completely adhered together to ensure the processing quality of the product.

[0029] As a further elaboration, in step S8, the temperature of the hot press forming is set at 150 °C, and the time of the hot press forming is 15 - 40 min.

[0030] As a further elaboration, in step S10, it also includes a protective surface treatment, which is used to paste a protective film on the exposed surface of the finished product to prevent scratches on the surface of the finished product caused by subsequent operations.

[0031] As a further elaboration, in steps S11 - S12, it also includes an oil spraying treatment, which is used to spray oil on the required surface of the finished product; after spraying oil, the finished product is put into an oven and taken out after the essential oil on its surface is dried.

[0032] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0033] 1. Through the two exhaust treatments in step S3, the air between the layers of the pre-laminated yarn is effectively exhausted, greatly reducing the formation of bubbles during the forming process, ensuring the tight structure inside the product, avoiding the negative impact of bubbles on the product quality, and thus reducing the defective rate;

[0034] 2. By starting to paste the preformed semi-finished product from one of its corners and gradually pushing the preformed semi-finished product to complete the pasting of the whole processing material in step S5, the phenomenon of air being trapped between the preformed semi-finished products is effectively reduced, further avoiding the negative impact of bubbles on the product quality, and thus reducing the defective rate;

[0035] 3. By placing the processing material at one end of the forming die first in step S6 and then gradually pushing the processing material to the other end of the forming die, the phenomenon of air entrapment between preformed semi-finished products is effectively reduced, further avoiding the negative impact of air bubbles on product quality, thereby reducing the defective rate.

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0046] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0047] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0048] In one embodiment of the present invention, as Figure 1-6 shown, a preparation process for mass-producing a running shoe carbon plate is provided, which specifically includes the following steps:

[0049] S1. Material preparation: Select carbon fiber prepreg of corresponding specifications as raw materials according to production requirements;

[0050] S2. Yarn cutting: Cut the carbon fiber prepreg through a cutting device, and perform cutting processing according to the actual required cutting angle and size to obtain angle yarn; among them, the cutting angle is determined according to the rigidity requirement of the finished product, such as carbon yarns of 0°, 19°, 45°, 90°, etc.

[0051] S3. Pre-laminating yarn: Pre-laminate two pieces of angle yarn distributed in a mirror image to obtain pre-laminated yarn, and the angles of the two pieces of angle yarn are in a mirror image and are pasted together, effectively reducing the phenomenon of confusion when angle yarns of different angles are pasted.

[0052] As Figure 1 shown, taking the longitudinal axis of the carbon plate as the central axis, the left is positive and the right is negative. In this embodiment, two pieces of angle yarn distributed in a mirror image generally are pasted with symmetric positive and negative angles, such as symmetric angles of 30°, 45°, 19°, 90°, etc. By pre-laminating the two mirror images in this way, the phenomenon of confusion when angle yarns of different angles are pasted is effectively reduced.

[0053] In other embodiments, the two mirror-surface distributed angle yarns can also be pasted against each other at asymmetric positive and negative angles. The specific pasting angles can be rotated according to the actual production requirements, as long as they can meet the production requirements of the product.

[0054] At the same time, exhaust treatment is required for both angle yarns during lamination; the angle yarns are flattened by a flattening jig to complete the first exhaust of the angle yarns. In this embodiment, a spatula can be used to flatten the angle yarns to make them smooth and discharge the gas inside them; in other embodiments, other flattening tools can also be used to flatten the angle yarns, as long as they can flatten the angle yarns, make them smooth, and discharge the gas inside them.

[0055] Then, the pre-laminated yarn after lamination is subjected to a second exhaust by an exhaust device to discharge the air inside the pre-laminated yarn layer to ensure the rigidity of the product. In this embodiment, a pinhole drum exhaust machine is used as the exhaust device. The staff feeds the pre-laminated yarn after lamination into the pinhole exhaust machine, and through the evenly sized and density-identical needle tips on the pressure roller, fine holes with the same density are pricked on the surface of the pre-laminated yarn, and the air in the pre-laminated yarn is discharged through the fine holes to ensure the rigidity of the product and thus improve the production quality of the product.

[0056] S4. Cutting the shape, the pre-laminated yarn is cut by a cutting device and processed according to the actual required processing shape to obtain a pre-shaped semi-finished product. By manufacturing the corresponding processing shape for the pre-shaped semi-finished product, it is ensured that the staff will not paste the pre-shaped semi-finished product crookedly during subsequent pre-shaping, improving the production quality of the product. At the same time, for some products that require carbon fiber braided patterns to be pasted on the exposed appearance surface, corresponding cutting jigs are also used for cutting to ensure that the pre-shaped semi-finished product can be accurately processed;

[0057] The pre-laminated yarn is cut into patches corresponding to different parts by a cutting device. These different parts include the half palm, the heel, the arch, etc., so as to facilitate the subsequent gluing connection of the patches to the corresponding strengthening positions of the pre-shaped semi-finished product. By cutting the patches of different parts, they can be pasted to the corresponding strengthening positions on the product during subsequent pre-shaping, thereby enhancing the rigidity of different parts of the product.

[0058] S5. Pre-shaping, the pre-shaped semi-finished product is laminated according to the actual required layered structure of the product to obtain a pre-shaped processed material;

[0059] The pre-shaped semi-finished product is laminated by a pre-shaping jig. Compared with traditional manual operations, it avoids the deviation generated during manual operations and improves the production quality of the product. During lamination, starting from a corner of the pre-shaped semi-finished product and gradually pushing the pre-shaped semi-finished product to complete the pasting of the processed material, such a pasting method can greatly reduce the phenomenon of air entrapment between the pre-shaped semi-finished products.

[0060] Among them, the preforming fixture can adopt a fixture for logging. Using a fixture made of wood substitute can improve the accuracy of preforming and reduce errors.

[0061] It also includes a refrigeration treatment, which is used to put the preformed processing material into a cold storage for refrigeration to ensure that the properties of the preformed processing material do not undergo chemical reactions due to the normal temperature environment. Especially for some processing materials that need to be stored, such as epoxy resin in pre-laid yarns, putting it into the cold storage for refrigeration can ensure that it does not become activated. However, after taking it out of the cold storage, it must be restored to room temperature before proceeding to the next operation.

[0062] S6. Upper mold: The forming mold is transported to the operation station through a mold transmission line. For example, a roller-type assembly line or a belt-type assembly line can be used for the mold transmission line. The staff at the operation station puts the preformed processing material into the forming mold.

[0063] The processing material is first placed at one end of the forming mold, and then gradually pushed to the other end of the forming mold. Such an upper mold method can greatly reduce the phenomenon of air entrapment between the mold and the processing material to ensure the processing quality of the product.

[0064] According to the structural shape of the product, a compaction fixture is used to press the processing material against the forming mold. The compaction fixture can be a bamboo piece. The product is compacted through the compaction fixture to ensure smooth resin flow and form a better plane. At the same time, after the upper mold, a release cloth is placed flat on the surface of the processing material to facilitate the demolding of the subsequent finished product. By placing the release cloth, the roughness of the product surface can be increased, which is beneficial to the assembly of the subsequent sole part, and the demolding efficiency can also be improved, facilitating the operation of the staff and improving the production efficiency of the product.

[0065] S7. Vacuum pumping: The forming mold with the processing material is placed into a vacuum bag, and all the air in the vacuum bag is pumped out through a vacuum pumping device. The vacuum pumping device can insert a vacuum rod into a autoclave for vacuum pumping, or use a vacuum pump outside the autoclave for vacuum pumping operation. After vacuum pumping, the vacuum bag is sealed. After vacuum pumping, it is necessary to check whether there is air leakage in the vacuum bag and make corresponding treatments according to the actual situation. If there is an air leakage phenomenon, the vacuum bag is replaced and the above steps are repeated for vacuum pumping treatment. If there is no air leakage, proceed to the next operation.

[0066] After vacuum pumping, the surface of the vacuum bag and the processing material should be completely adhered together, that is, there should be no wrinkles between the vacuum bag and the processing material to avoid air entrapment in the wrinkles and ensure the processing quality of the product.

[0067] S8. Hot pressing forming: Place the vacuum bag equipped with the forming mold on the movable frame, use the pushing device to push the movable frame into the autoclave, adjust the temperature and pressure according to the corresponding resin for production, and then perform hot pressing forming on the forming device through the autoclave;

[0068] The temperature of hot pressing forming is set at 150 °C, and the time of hot pressing forming is 15 - 40 min. For example, the forming time of epoxy resin is 40 min, and the forming time of fast-curing resin is 15 - 20 min, etc. Among them, if some resins require pre-curing treatment, the curing operation needs to be carried out in advance to ensure the smooth progress of subsequent hot pressing forming.

[0069] S9. Demolding: Exhaust the autoclave, and after ensuring safety, use the pushing device to take out the movable frame. After the mold cools to 80 °C, then demold the forming mold. At this time, the finished product can be smoothly attached to the demolding cloth, and the staff can take out the finished product from the forming mold to obtain the demolded finished product; among them, the pushing device can be a pulley cart.

[0070] It also includes protective surface treatment, which is used to paste a protective film on the exposed surface of the finished product to prevent scratches on the surface of the finished product caused by subsequent operations. In this embodiment, the protective film can be R glue, masking paper, tape paper, pearlescent paper, etc.

[0071] S10. Grinding: According to the production requirements of the product, use grinding equipment to grind the periphery of the demolded finished product; in this embodiment, the grinding equipment can be sandpaper grinding wheel or grinding machine. Grind the periphery of the finished product through the grinding equipment to prevent the finished product from stabbing the staff.

[0072] S11. Sandblasting: In this embodiment, spray corundum on the surface of the product to make its surface uneven, improving the subsequent fit between the product and the midsole; through the sandblasting operation, the roughness of the surface of the finished product is increased, improving the subsequent fit between the product and the midsole.

[0073] In other embodiments, wet grinding can also be used to enhance the roughness of the surface of the finished product, improving the subsequent fit between the product and the midsole.

[0074] It also includes oil spraying treatment, which is used to spray oil on the required surface of the finished product; the oil-sprayed finished product is placed in an oven, and taken out after the essential oil on its surface is dried. Through the oil spraying treatment, to ensure that the surface of the product has a smooth exposed effect.

[0075] S12. Weighing: Place the sandblasted finished product on the weighing equipment for weighing detection, and select the defective products that do not meet the product quality requirements; by weighing the finished product, the defective products among them are screened out, thus ensuring the production quality of the product.

[0076] S13, metal detection, put the finished products that have passed the weighing into the metal detector for metal detection, and select the defective products with metal components inside the finished products; through metal detection, the defective products containing metal components can be screened out, thereby improving the safety of the product.

[0077] S14. Packaging: Pack the qualified finished products according to the packaging requirements of the products. The packaged finished products are classified according to the numbers and the quantity of the numbers. At the same time, the packaged finished products are vacuumed to effectively protect the surface of the products from scratches. If there are glossy surfaces on the surface of the products that need to be protected, plastic film or soft paper needs to be added between the glossy surfaces to protect the surface of the products from scratches.

[0078] Through the two exhaust treatments in step S3, the air between the layers of the pre-stacked yarn is effectively removed, which greatly reduces the formation of bubbles during the molding process, ensures the compact structure inside the product, avoids the negative impact of bubbles on product quality, and thus reduces the defective product rate;

[0079] By pasting the preformed semi-finished product from one corner in step S5 and gradually pushing the preformed semi-finished product to complete pasting of the entire piece of processing material, the phenomenon of air inclusion between the preformed semi-finished products is effectively reduced, further avoiding the negative impact of air bubbles on product quality, thereby reducing the defective product rate;

[0080] By placing the processed material at one end of the molding die in step S6 and then gradually pushing the processed material to the other end of the molding die, the phenomenon of air inclusion between the preformed semi-finished products is effectively reduced, further avoiding the negative impact of bubbles on product quality, thereby reducing the defective product rate.

[0081] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementations of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
