Description

Technical Field

[0001] The invention relates to the field of automobile covering, in particular to a hydraulic covering device and a hydraulic covering system. Background Art

[0002] In the traditional automatic coating process, vacuum adsorption machines are mainly used to heat the silicone film through a heat source, and then the film completes the coating of the fabric and the frame under the action of vacuum adsorption. It can only complete the coating of large flat surfaces and low curvature surfaces. And due to the inability to complete the flanging coating and the low latent heat of the adsorption film, the uniformity of the fabric heating cannot be guaranteed, resulting in unstable glue activation and uneven bonding, which affects the bonding between the fabric and the frame.

[0003] The localized covering requires the use of special yin and yang membranes and clamps. Dedicated membranes and clamps must be designed for each product, which requires a large one-time investment and is not compatible with other products. The flexibility is low and cannot meet the future trend of small-batch flexibility in the automotive industry. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a hydraulic coating device, a hydraulic coating device and a hydraulic coating system.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a hydraulic coating equipment, including an automatic feeding device, a pressure device and a constant temperature and pressure liquid pool for skin, wherein the automatic feeding device is used to take and place automobile coating products, and the pressure device is used to press the automobile coating products in the constant temperature and pressure liquid pool for skin. The constant temperature and pressure liquid pool for skin is used to provide constant temperature and pressure for the automobile coating products. Since the coating of automobile coating products is carried out in the constant pressure liquid pool for skin. On the one hand, since the liquid pool is flexible, it can not only complete the coating of large planes and low curvature surfaces, but also the coating of local small flanges. Moreover, the flexible liquid pool will not damage the automobile coating products that need to be coated, thereby improving the qualified rate of the products. On the other hand, due to the constant temperature and constant pressure characteristics of the liquid pool, and the flexible liquid pool can fully cover the automotive wrapping product, thus providing uniform heat transfer to the automotive wrapping product to be covered, thereby making the automotive wrapping product to be covered evenly heated, and the temperature is closer to the temperature of the constant temperature and constant pressure liquid pool, thereby improving the activation consistency of the glue inside the automotive wrapping product to be covered, thereby improving the bonding strength of the various parts inside the automotive wrapping product to be covered (frame and wrapping material), and improving the service life of the automotive wrapping product to be covered. And due to the flexible characteristics of the liquid, it can be applied to automotive wrapping products of all shapes that need to be covered, thereby improving the adaptability of the hydraulic wrapping equipment of the present invention.

[0006] Furthermore, in the hydraulic coating equipment, the automatic feeding device is a robot, and the pressure device is a pressure head. After the robot clamps the automobile coating product and places it into the constant temperature and pressure liquid pool of the skin, the pressure head applies pressure to the automobile coating product.

[0007] Furthermore, in the hydraulic coating device, the liquid in the constant temperature and constant pressure liquid pool is a Newtonian fluid or a non-Newtonian fluid, the Newtonian fluid may be water, and the non-Newtonian fluid may be a concentrated solution or suspension of a polymer. The liquid in the constant temperature and constant pressure liquid pool is wrapped by the skin.

[0008] Furthermore, in the hydraulic wrapping equipment, the car wrapping product is a car wrapping material and a frame, the car wrapping material and the frame are connected by glue, and the car wrapping material can be one of PVC skin, PU skin, genuine leather or knitted fabric.

[0009] Furthermore, in the hydraulic coating equipment, the pressure device presses the automobile coating product in the constant temperature and pressure liquid pool of the skin and maintains it for 10 seconds to 60 seconds.

[0010] Furthermore, the present invention also claims protection for a hydraulic coating system, which comprises the hydraulic coating device according to any one of claims 1-5.

[0011] Furthermore, in the hydraulic coating system, the hydraulic coating system also includes a skeleton pre-processing system, and the skeleton pre-processing system is used to detect and process the skeleton to obtain a qualified skeleton for bonding with the coating material.

[0012] Furthermore, in the hydraulic coating system, the hydraulic coating system also includes an automobile coating product post-processing system, and the automobile coating product post-processing system is used to post-process the automobile coating product to improve the qualified rate of the automobile coating product.

[0013] Furthermore, in the hydraulic coating system, the hydraulic coating system may also include an automatic visual inspection system for product defects, and the automatic visual inspection system for product defects is used to automatically inspect the hydraulically coated products.

[0014] Furthermore, the present invention also claims protection for a method for using a hydraulic coating device, using the hydraulic coating device as described in claims 1-5, which includes the following steps: step S1, first operate the automatic loading device to place the automobile coating product in the constant temperature and constant pressure liquid pool of the skin; step S2, operate the pressure device to apply pressure to the automobile coating product placed in the constant temperature and constant pressure liquid pool of the skin in step S1 and maintain it for 10 seconds to 60 seconds; step S3, operate the automatic loading device to take the automobile coating product to which the pressure device applies pressure in step S2 out of the constant temperature and constant pressure liquid pool of the skin.

[0015] If the coating equipment of the prior art needs to complete the coating of large flat surfaces and low curvature surfaces, a vacuum adsorption machine is usually used. The vacuum adsorption machine mainly heats the silicone film through a heat source, and then the film completes the coating action of the fabric and the frame under the action of vacuum adsorption. However, due to the inability to complete the flanging coating and the small latent heat of the adsorption film, the uniformity of the fabric heating cannot be guaranteed, which leads to the unstable degree of glue activation in the automobile coating product, making the automobile coating product easy to separate from each other due to the insufficient bonding force of the internal parts, resulting in a reduction in product life. In the prior art, the coating of small local turns needs to be completed with the help of special yin and yang fetal membranes and clamps. Each product must be designed with a special fetal membrane and clamp, which requires a large one-time investment and is not compatible with other products. The degree of flexibility is low and it is impossible to quickly meet the future trend of small-batch flexibility in the automotive industry. Compared with the above-mentioned equipment of the prior art, the present invention provides a hydraulic coating equipment, which includes an automatic feeding device, a pressure device and a constant temperature and pressure liquid pool for the skin. The automatic loading device is used to pick up and place the automobile covering product, and the pressure device is used to press the automobile covering product into the constant temperature and pressure liquid pool of the skin, and the constant temperature and pressure liquid pool of the skin is used to provide constant temperature and pressure to the automobile covering product. The hydraulic covering equipment of the present invention uses the constant temperature and pressure liquid pool. On the one hand, since the liquid pool is constant temperature and pressure, the automobile covering product can be heated at a constant temperature, so that the interior of the automobile covering product is heated evenly, and the activation degree and curing degree of the glue in the automobile covering product are consistent, thereby improving the bonding force between the various parts inside the automobile covering product. On the other hand, since the constant temperature and pressure liquid pool contains liquid, the hydraulic covering equipment of the present invention is more flexible and will not cause damage to the automobile covering product that needs to be coated.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In car wrapping, in order to improve the perceived quality of car interior, the car interior needs to be wrapped. In the traditional wrapping process, a vacuum adsorption machine is mainly used to heat the silicone film through a heat source, and then the film completes the wrapping action of the fabric and the frame under the action of vacuum adsorption. However, this process can only complete the wrapping of large flat surfaces and low curvature surfaces, and is limited by the inability to complete the flanging wrapping and the small latent heat of the adsorption film, and the uniformity of the fabric heating cannot be guaranteed, which will cause the glue activation degree to be unstable, and then cause uneven adhesion between the fabric and the frame, affecting the bonding strength between the frame and the fabric. At the same time, because the force on the fabric is not uniform in the traditional wrapping process, the surface of the fabric will be damaged, which also affects the quality of the wrapped product. In actual wrapping production, the inventor observed the above phenomenon and proposed a new hydraulic wrapping equipment. As Figure 1 As shown, the hydraulic coating equipment at least includes a feeding device, which is used to pick up and place automobile coating products. The automobile coating products here may include a skeleton and a coating material coated on the skeleton. Glue is sprayed between the skeleton and the coating material. The sprayed glue may be automobile glue. The viscosity of the automobile glue may be 10cps-300cps, and the solid content may be 5%-20%. Automobile glue of this viscosity has greater fluidity. It can be quickly sprayed on the coating material, thereby greatly improving production efficiency. The leather is usually PVC skin, PU skin, genuine leather or knitted fabric. The pressure device is used to press the automobile coating product into the constant temperature and pressure liquid pool of the skin. The constant temperature and pressure liquid pool of the skin is used to provide constant temperature and pressure to the automobile coating product. In this way, when it is necessary to coat the automobile coating product, it is only necessary to use the feeding device to move the automobile coating product into the constant temperature and pressure liquid pool of the skin, and then use the pressure device to apply a certain pressure to the automobile coating product placed in the constant temperature and pressure liquid pool. After that, the automobile coating product placed in the constant temperature and pressure liquid pool of the skin is taken out by the automatic feeding device to complete the automobile coating. In the present invention, since a constant temperature and pressure liquid pool is used when coating the automobile coating product, compared with the traditional equipment for coating the automobile coating product, due to the flexibility of the liquid pool, the damage to the appearance of the automobile coating product to be coated can be greatly reduced, and the product qualification rate can be improved. At the same time, due to the constant temperature and pressure characteristics of the liquid pool, a uniform and stable temperature can be provided to the automobile coating product to be coated, so that the temperature at which the glue between the skeleton bonded by glue and the coating material inside the automobile coating product to be coated is more accurate and more consistent. The obtained coated automobile coating product has the strongest bonding force in each part and the most uniform bonding force in each part. Therefore, the product produced by the hydraulic coating equipment provided by the present invention is better than other equipment for producing automobile coating products in the prior art.

[0023] Further, in the present invention, the automatic feeding device can be a manipulator, which can improve the level of factory automation, help improve efficiency and reduce costs. The pressure device can be a pressure head. In the present invention, the hydraulic coating device can also include a control system, and the on-site worker issues instructions to the manipulator through the control system or the control system according to a pre-set program. After the manipulator receives the instruction, the manipulator clamps the automobile coating product and then puts it into the constant temperature and constant pressure liquid pool, and then the pressure head applies pressure to the automobile coating product placed in the constant temperature and constant pressure liquid pool under the control of the control system. The pressure is transmitted to the constant temperature and constant pressure liquid pool, and the constant temperature and constant pressure liquid pool reacts with the automobile coating product. Since the constant temperature and constant pressure liquid pool is flexible, it will not cause damage to the automobile coating product. On the one hand, it improves the qualified rate of the product. On the other hand, the flexible liquid pool can also completely wrap the automobile coating product. In this way, the hydraulic coating equipment of the present invention can not only complete the coating of large planes and low curvature surfaces, but also complete local small turning coating. At the same time, since the liquid pool is at a constant temperature and pressure, and the liquid pool can completely wrap the automobile wrapping product, the temperature of the liquid pool can be thoroughly and accurately transferred to the automobile wrapping product, so that the glue inside the automobile wrapping product can be fully activated, thereby increasing the service life of the automobile wrapping product.

[0024] Furthermore, the constant temperature and pressure tank contains a Newtonian fluid or a non-Newtonian fluid. When the liquid in the constant temperature and pressure tank is a Newtonian fluid, it can be water. When the liquid in the constant temperature and pressure tank is a non-Newtonian fluid, it can be a concentrated solution or suspension of a polymer. The concentrated solution or suspension of the polymer can specifically be polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, polyester, rubber solution, various engineering plastics, melts and solutions of chemical fibers, etc. Or it can be a material such as starch liquid. As long as the liquid in the constant temperature and pressure tank has flexibility and high latent heat performance, it can be used. Constant temperature and pressure can provide a stable coating pressure for coating. And flexibility can realize the coating operation of the back flange of the product. High latent heat can stabilize the uniform temperature field, ensure sufficient latent heat to heat the fabric without obvious temperature fluctuations, and ensure that the glue activation and curing temperature are more accurate.

[0025] Furthermore, in the hydraulic coating equipment of the present invention, the control system can control the pressure device, which can be specifically the pressure head. When the control system controls the pressure head to apply pressure to the automobile coating product placed in the constant temperature and constant pressure liquid pool, the automobile coating product needs to be pressed for 10 seconds to 60 seconds. In this way, on the one hand, the temperature in the constant temperature and constant pressure liquid pool can be transferred to the automobile coating product to activate the glue for a period of time. On the other hand, the production efficiency can also be improved.

[0026] The present invention also claims protection for a hydraulic coating system, which contains the hydraulic coating device. In addition to the hydraulic coating device, it may also include a skeleton pre-treatment system, which is used to detect and process the skeleton to obtain a qualified skeleton for bonding with the coating material. This is because once the glue is solidified, the skin can no longer be torn off the skeleton intact. Part of the back bubble and glue will stick to the skeleton when the skin is torn off and cannot be cleaned. Therefore, before coating, workers are required to carefully check the skeleton and the coating skin to reduce the defective rate. Usually, when there are defects such as discontinuities, depressions, particles, etc. on the surface of the skeleton, it is necessary to grind the surface of the skeleton with sandpaper, and if necessary, it is necessary to apply putty appropriately to make the surface of the skeleton smooth.

[0027] In addition to the hydraulic coating device and the pre-treatment system, the hydraulic coating system of the present invention may also include a post-treatment system. As the name implies, the post-treatment system is used to perform post-treatment on the coated automobile coating product, which is mainly used to improve the qualified rate of the automobile coating product. Specifically, the post-treatment system is used to cut off the excess coating material on the coated automobile coating product. If the on-site workers find that there is excess coating material on the coated product, they can use scissors or wallpaper cutters to cut off the excess coating material after reverse wrapping.

[0028] The hydraulic coating system of the present invention may also include an automatic visual detection system for product defects. After the automobile coating product is pressed and taken out from the constant temperature and constant pressure liquid pool of the skin, an intelligent visual defect detection system is set. The purpose is to quickly discover product defects and improve work efficiency. The intelligent visual detection system may include a high-definition camera and visual analysis software. The high-definition camera is used to take pictures and record the products to be inspected. The visual analysis software is used to analyze the surface of the product recorded in the picture. When the visual analysis software finds defects on the product, it can issue a reminder or mark it to let the on-site staff know.

[0029] Preferably, the present invention may also claim to protect the method for using the hydraulic coating equipment. Specifically, when the user of the hydraulic coating equipment needs to use the hydraulic coating equipment, he or she may control the automatic loading device through the control system to place the automobile coating product in the constant temperature and pressure liquid pool of the skin. The control here may be manual control or program control, which is not limited here. Then the control system may control the pressure device to apply pressure to the automobile coating product placed in the constant temperature and pressure device, and the pressure may be maintained for 10 seconds to 60 seconds to transfer the temperature in the constant temperature and pressure liquid pool to the automobile coating product for a period of time. Then the user of the hydraulic coating equipment takes the automobile coating product out of the constant temperature and pressure liquid pool of the skin.

[0030] In summary, the hydraulic coating equipment of the present invention includes an automatic feeding device, a pressure device and a constant temperature and pressure liquid pool for the skin. The automatic feeding device is used to take and place the automobile coating product, and the pressure device is used to press the automobile coating product in the constant temperature and pressure liquid pool of the skin. The constant temperature and pressure liquid pool of the skin is used to provide a constant temperature and pressure to the automobile coating product. The automatic feeding device clamps the automobile coating product to the constant temperature and pressure liquid pool, and the pressure device is used to apply pressure to the automobile coating product in the constant temperature and pressure liquid pool. The constant temperature and pressure liquid pool of the skin is used to provide a constant temperature and pressure to the automobile coating product. In this way, since the liquid pool is flexible, compared with the coating equipment in the prior art, the hydraulic coating equipment of the present invention will not cause appearance damage to the automobile coating product to be coated. At the same time, since the liquid pool is flexible, the liquid pool can completely wrap the automobile wrapping product, thereby not only completing the wrapping of large planes and low-curvature surfaces, but also completing the wrapping of small parts. It can adapt to automobile wrapping products of various shapes, and does not require the design of special fetal membranes and clamps for each product, thereby improving the versatility of the hydraulic wrapping equipment of the present invention. Since the liquid pool is constant temperature and pressure, and the liquid pool can completely wrap the automobile wrapping product, the various parts of the automobile wrapping product can be heated evenly, and the heating is also more precise, that is, the temperature of the automobile wrapping product is more consistent with the temperature in the liquid pool, so that the activation degree and curing degree of the glue inside the automobile wrapping product are consistent, thereby improving the bonding force between the various parts inside the automobile wrapping product, and improving the service life of the wrapped automobile wrapping product.

[0031] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
