Description

Technical Field

[0001] The invention relates to the technical field of spraying, in particular to a flexible coating production line. Background Art

[0002] In traditional spraying production technology, spraying production lines are generally set up according to the specific spraying process required by the product. Therefore, the number and position relationship of the spraying room, leveling area and oven of the spraying production line are fixed, and the way the transmission line connects the spraying room, leveling equipment and oven is also fixed, which is only suitable for spraying operations of specific processes. For example, in order to achieve a one-spray-one-bake process, the spraying production line is usually equipped with a spraying room, a leveling area, an oven, and a circulating transmission line that connects the above-mentioned one spraying room, one leveling area and one oven in series. Therefore, this kind of spraying production line will be difficult to efficiently complete complex spraying production processes such as multiple spraying and one baking.

[0003] In the related art, in order to improve the versatility of the spraying production line, for example, referring to Figure 1 In order to realize the spraying process of N (N is greater than or equal to 2) spraying and M (M is less than or equal to N) baking, an intermediate transmission line 50 is added on the basis of the traditional one-spray-one-bake spraying production line. The intermediate transmission line 50 connects two points on the circulating transmission line 40, and along the transmission direction of the circulating transmission line 40, one end of the intermediate transmission line 50 is located before the spraying room 10, and the other end is located between the leveling area 20 and the baking oven 30, so as to transmit the leveled but not dried materials to the spraying room 10 again, so as to realize the spraying production process in which the number of spraying times is greater than the number of drying times. However, along the transmission direction of the circulating transmission line 40, other expansion areas such as the unloading area and the loading area are also provided between the spray chamber 10 and the oven 30. Therefore, in addition to the finished workpieces that have completed all the spraying and drying processes will flow through the unloading area, the semi-finished workpieces that have completed drying more than 1 time but less than M (here M is greater than or equal to 2) times will also pass through the unloading area. Therefore, it is necessary to accurately screen out the finished workpieces in the unloading area. If the screening is inaccurate, the semi-finished workpieces will be mistakenly unloaded in the unloading area, and the finished workpieces will flow to the spray chamber 10 again, which will easily lead to an increase in the product defective rate. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a flexible coating production line, which not only has good process versatility, but also helps to improve the yield rate.

[0005] According to an embodiment of the present invention, the flexible coating production line includes a control module, a spraying line, a first leveling line, a second leveling line, a baking line, a first cooling line, a first traverse line, a second traverse line, a third traverse line and a loading and unloading transmission line; the spraying line passes through the spraying room; the head end of the first leveling line in the conveying direction is connected to the tail end of the spraying line in the conveying direction; the head end of the second leveling line in the conveying direction is connected to the tail end of the first leveling line in the conveying direction; the baking line passes through the oven and is arranged in parallel with the second leveling line; the baking line has a first end and a second end opposite to each other and can transmit in both directions; the first cooling line is arranged in parallel with the second leveling line and passes through the first cooling zone; the first traverse line sequentially connects the tail end of the first leveling line in the conveying direction, the first end of the baking line and the head end of the first cooling line in the conveying direction, and the first traverse line can transfer the workpiece output from the first leveling line to the baking line, or output from the first end of the baking line The workpiece is transferred to the first cooling line; the second transverse line can be transmitted in both directions, and the second transverse line connects the head end of the spraying line in the conveying direction, the tail end of the second leveling line in the conveying direction, the second end of the baking line and the tail end of the first cooling line in the conveying direction; the head end of the third transverse line in the conveying direction is connected to the second leveling line, and the tail end of the third transverse line in the conveying direction is connected to the spraying line; and in the conveying direction of the spraying line, the connection point of the third transverse line and the spraying line is located at the front side of the spraying room; the loading and unloading transmission line is sequentially provided with a unloading area and a loading area along the conveying direction, and the head end of the loading and unloading transmission line in the conveying direction is connected to the tail end of the first cooling line in the conveying direction, and the tail end of the loading and unloading transmission line in the conveying direction is connected to the head end of the spraying line in the conveying direction; the control module is electrically connected to the spraying line, the first leveling line, the second leveling line, the baking line, the first cooling line, the first transverse line, the second transverse line, the third transverse line and the loading and unloading transmission line.

Yes; at the same time, by setting up a second transverse moving line, the workpiece after passing through the baking line and the baking oven can be returned to the head end of the spraying line through the second transverse moving line for spraying again according to the process requirements. That is, the semi-finished workpiece that needs to be sprayed with paint again after baking does not need to pass through the loading and unloading transmission line to return to the head end of the spraying line. Therefore, only the finished workpiece can pass through the unloading area, so that there is no need for screening in the unloading process, which is not only beneficial to improving the unloading efficiency, but also can effectively improve the problem of incorrect unloading of semi-finished workpieces in the middle, and thus is beneficial to improving the yield rate.

The tail end is connected to the head end of the conveying direction of the spray line 100; the control module is electrically connected to the spray line 100, the first leveling line 210, the second leveling line 220, the baking line 300, the first cooling line 400, the first lateral line 510, the second lateral line 520, the third lateral line 530, the loading and unloading transmission line 600, the oven 30 and the first cooling zone 60, and can control the working status of the spray line 100, the first leveling line 210, the second leveling line 220, the baking line 300, the first cooling line 400, the first lateral line 510, the second lateral line 520, the third lateral line 530, the loading and unloading transmission line 600, the oven 30 and the first cooling zone 60.

[0025] It should be understood that the flexible coating production line of this embodiment, when a spraying and baking process is required, can control the loading and unloading transmission line 600, the spraying line 100, the first leveling line 210, the second leveling line 220, the second transverse line 520, the baking line 300, the first transverse line 510 and the first cooling line 400 to work together through the control system, so that the workpiece loaded from the loading area of ​​the loading and unloading transmission line 600 can be sprayed in sequence through the spraying line 100 and the spraying room 10, leveled through the first leveling line 210 and the second leveling line 220, transferred to the baking line 300 through the second transverse line 520, baked through the baking line 300 and the oven 30, transferred to the first cooling line 400 through the first transverse line 510, cooled through the first cooling line 400 and the first cooling zone 60, and returned to the unloading area of ​​the loading and unloading transmission line 600 to complete the workpiece unloading.

[0026] When a spraying process of N (N is greater than or equal to 2) spraying and N baking is required, the control system can be used to control the loading and unloading transmission line 600, the spraying line 100, the first leveling line 210, the second leveling line 220, the second traverse line 520, the baking line 300, the first traverse line 510, and the first cooling line 400 to work in coordination, so that the workpiece loaded from the loading area of ​​the loading and unloading transmission line 600 is sequentially sprayed through the spraying line 100, the first leveling line 210, the second leveling line 220, the second traverse line 520, the baking line 300, the first traverse line 510, and the first cooling line 400 in the first few sprayings. 20. The second transverse line 520, the baking line 300, the first transverse line 510, the first cooling line 400 and the second transverse line 520 are circulated, and then the workpiece returns to the spraying line 100 for the last spraying. Subsequently, the workpiece passes through the first leveling line 210, the second leveling line 220, the second transverse line 520, the baking line 300, the first transverse line 510, the first cooling line 400 in sequence to the loading and unloading transmission line 600, and the workpiece unloading is completed in the unloading area of ​​the loading and unloading transmission line 600.

[0027] When a spraying process of N (N is greater than or equal to 2) spraying and M (M is less than or equal to N) baking is required, that is, a baking process is not required after part of the spraying process, and a baking process is required after part of the spraying process, for a spraying process that requires a baking process after the spraying process, the workpiece can be passed through the first leveling line 210, the second leveling line 220 and the second transverse line 520 when it flows out of the spraying line 100, so that the workpiece enters the baking line 300 and the baking oven 30 for baking after the painting process is completed; and for a spraying process that does not require a baking process after the spraying process and leveling, the workpiece can be passed through the first leveling line 210, the second leveling line 220 and the third transverse line 530 when it flows out of the spraying line 100, so that the workpiece can return to the position of the spray line 100 located in the front side of the spraying room 10 after the painting process and leveling are completed. , so that it can enter the spraying room 10 again under the transportation of the spraying line 100 to spray the next layer of paint; for example, when a 2-spray 1-bake spraying process is required, the workpiece is transported to the spraying line 100 and the spraying room 10 via the loading and unloading transmission line 600 to complete the spraying of the first layer of paint, and then flows through the first leveling line 210 and the second leveling line 220 for leveling, and then the workpiece is transported back to the spraying line 100 and the spraying room 10 through the third transverse line 530 to complete the spraying of the second layer of paint, and then after the workpiece flows through the first leveling line 210 and the second leveling line 220 for leveling, the workpiece is transported to the baking line 300 through the second transverse line 520 for baking to dry the paint, and then the workpiece is transported to the first cooling line 400 through the first transverse line 510 for cooling, and finally the workpiece flows through the loading and unloading transmission line 600 for unloading.

[0028] From the above description, it can be known that the flexible coating production line of this embodiment, by setting the second leveling line 220 and the third transverse line 530, can make the workpiece return to the spraying line 100 to the front side of the spraying room 10 via the first leveling line 210, the second leveling line 220 and the third transverse line 530 after the spraying in the spraying room 10 is completed, so that the workpiece can be sprayed again without passing through the baking line 300 and the baking oven 30 for baking. Therefore, the flexible coating production line of this embodiment can adapt to the conventional one-spray-one-bake process and N (N is greater than or equal to 2) spray-N-bake process, and can also adapt to the spraying process in which the number of spraying times is greater than the number of drying times. It has good general performance; at the same time, by setting up the second transverse movement line 520, the workpiece after passing through the baking line 300 and the baking oven 30 can be returned to the head end of the spraying line 100 through the second transverse movement line 520 according to the process requirements for spraying again. That is, the semi-finished workpiece that needs to be sprayed with paint again after baking does not need to pass through the loading and unloading transmission line 600 to return to the head end of the spraying line 100, so that only the finished workpiece can pass through the unloading area, so that there is no need for screening in the unloading process, which is not only beneficial to improving the unloading efficiency, but also can effectively improve the problem of incorrect unloading of semi-finished workpieces in the middle, which is beneficial to improving the yield rate.

[0029] It is understood that in some of these embodiments, reference Figure 2 , the second transverse line 520 is located between the head end of the spraying line 100 in the conveying direction and the tail end of the second leveling line 220 in the conveying direction, passes through the second cooling zone 70 and forms a second cooling line, so that the workpiece transferred to the spraying line 100 through the second transverse line 520 can be cooled on the second transverse line 520; for example, in one embodiment, for the workpiece that needs to be baked and needs to be painted again after completing the current painting, after the workpiece completes the current painting and enters the first leveling line 210, it can also be selected to transfer the workpiece output by the first leveling line 210 to the first end of the baking line 300 through the first transverse line 510, and after baking is completed, the workpiece is transferred from the second end of the baking line 300 to the spraying line 100 again through the second transverse line 520, and the workpiece is cooled while being transferred; the above path is compared with the second transverse line 220 in sequence. , the second transverse line 520, the baking line 300, the first transverse line 510, the first cooling line 400, the second transverse line 520 and then returning to the spraying line 100 can be made shorter to make the production efficiency higher; or, in some other embodiments, for the workpiece that needs to be baked and sprayed again after the current painting is completed, and the baking time required for the paint sprayed last time is relatively long (or the baking heating temperature is high), after the workpiece completes the current painting and enters the first leveling line 210, it can also be selected to return to the spraying line 100 via the second leveling line 220, the second transverse line 520, the baking line 300, the first transverse line 510, the first cooling line 400, the second transverse line 520 in sequence, so as to cool the workpiece twice with the help of the first cooling line 400 and the second cooling line in the second transverse line 520 to improve the cooling effect.

[0030] In some of these embodiments, reference Figure 2, the baking line 300 includes multiple baking lines 300, and the multiple baking lines 300 are arranged in parallel with each other; it should be understood that by setting up multiple baking lines 300, the baking efficiency can be improved on the one hand; for example, after a batch of multiple workpieces complete the spraying and leveling of each layer of paint, the multiple workpieces can be transferred to different baking lines 300 through the first transverse line 510 or the second transverse line 520 for simultaneous baking to improve the baking efficiency; by setting up multiple baking lines 300, on the other hand, it is also possible to set the baking temperature in each baking line 300 to a baking temperature that matches the various layers of paint in the workpiece according to the differences in the various layers of paint in the workpiece; for example, when two baking lines 300 are provided and the workpiece needs to undergo a two-spray and two-bake process, the baking temperature of one of the baking lines 300 can be selected to be set to a temperature that matches the primer Matching, and the baking temperature of another baking line 300 can be selected to match the topcoat, and after the workpiece is transported to the spraying room 10 to complete the primer spraying, it can be transported to the baking line 300 with a baking temperature matching that of the primer through the first leveling line 210 and the first transverse line 510 in sequence for baking, and then transported back to the spraying line 100 through the second transverse line 520 for topcoat spraying. After the topcoat spraying is completed, the workpiece is then transported to the baking line 300 with a baking temperature matching that of the topcoat through the first leveling line 210, the second leveling line 220, and the second transverse line 520 in sequence for baking, and after baking is completed, it is transported to the loading and unloading transmission line 600 through the first transverse line 510 and the first cooling line 400 to complete unloading, so that the baking and cooling of the primer and the topcoat can be carried out separately.

[0031] It should be understood that, in one embodiment, two baking lines 300 are provided, and in order to save space, the two baking lines 300 are respectively arranged above the second leveling line 220 and the first cooling line 400 .

[0032] It is understandable that, since dust and other impurities may adhere to the surface of the workpiece before loading and during the transmission on each transmission line, in order to prevent the impurities from affecting the quality of the finished product after spraying, in some embodiments, reference is made to Figure 2 The spray line 100 passes through the pretreatment area 80, and the pretreatment area 80 is located at the front side of the spray chamber 10 and is used to pretreat the workpiece to remove dust and other impurities on the surface of the workpiece before each spraying, thereby improving the spraying quality.

[0033] It is understandable that some paints need to be subjected to light treatment such as ultraviolet light irradiation after spraying and drying. Therefore, in order to meet the spraying process requirements of paints that need light treatment, in some embodiments, reference is made to Figure 2The flexible coating production line also includes a light treatment zone 90, and the first cooling line 400 passes through the light treatment zone 90, and along the conveying direction of the first cooling line 400, the light treatment zone 90 is located in front of the first cooling zone 60, so that after the workpiece is sprayed with the paint that needs to be light treated, the workpiece can pass through the first leveling zone 20, the second leveling zone 20, the second transverse line 520, the baking line 300, and the first transverse line 510 in sequence and then enter the first cooling line 400, and is first light treated and then cooled under the conveyance of the first cooling line 400.

[0034] It is understandable that, in order to enable the workpieces that have been sprayed to be automatically stored and transported after unloading, in some embodiments, the flexible coating production line also includes a storage line 700, and a unloading machine 710 is provided in the unloading area. The head end of the storage line 700 in the transmission direction is connected to the unloading machine 710. The unloading machine 710 is used to transfer the workpieces that have been sprayed to the storage line 700, and the storage line 700 is used to transport and transfer the workpieces that have been sprayed to storage equipment such as the smart warehouse 740. For example, in some embodiments, refer to Figure 3 The flexible coating production line also includes a first visual inspection system 720, an automatic packaging machine 730 and an intelligent warehouse 740, wherein the first visual inspection system 720, the automatic packaging machine 730 and the intelligent warehouse 740 are arranged in sequence along the transmission direction of the storage line 700. Driven by the storage line 700, the workpiece that has completed spraying will be able to pass through the first visual inspection system 720 for inspection to identify whether the workpiece is qualified, and the workpiece that has passed the inspection can continue to move to the position of the automatic packaging machine 730 for packaging under the drive of the storage line 700, and the workpiece that has completed packaging can continue to move to the intelligent warehouse 740 for storage under the drive of the storage line 700.

[0035] It is understandable that, in order to be able to connect the molding equipment of the workpiece blank and automatically and continuously transport the produced workpiece blank to the loading and unloading transmission line 600, in some embodiments, the flexible coating production line also includes a feeding line 800, and a loading machine 840 is provided in the loading area. The tail end of the feeding line 800 in the transmission direction is connected to the loading machine 840, and the head end of the feeding line 800 is connected to the molding equipment of the workpiece blank and is used to transfer the workpiece blank produced by the molding equipment, and the loading machine 840 is used to transfer the workpiece blank from the feeding line 800 to the loading and unloading transmission line 600. For example, in some embodiments, refer to Figure 3The flexible coating production line also includes a blank forming machine 810, an automatic trimming machine 820 and a second visual inspection system 830. The blank forming machine 810 (for example, it can be a molding equipment such as an injection molding machine), the automatic trimming machine 820 and the second visual inspection system 830 are arranged in sequence along the transmission direction of the feeding line 800. Driven by the feeding line 800, the workpiece blank produced by the blank forming machine 810 will be able to move to the automatic trimming machine 820 for edge contour correction, and the workpiece blank that has completed trimming can continue to move to the second visual inspection system 830 for inspection under the drive of the feeding line 800 to identify whether the blank workpiece is qualified, and the workpiece blank that has passed the inspection can be moved to the loader 840, and finally transferred to the loading and unloading transmission line 600 through the loader 840 to complete the loading before spraying.

[0036] It is understandable that paint mist will be generated during the spraying process, and as the spraying continues, the paint mist concentration in the air in the spraying room 10 will gradually increase. If it is not handled in time, it will increase the safety hazard of the spraying room 10. In order to reduce the paint mist concentration in the air in the spraying room 10 to improve safety, in some embodiments, reference is made to Figure 3 The flexible coating production line also includes a paint mist capture device 910, an exhaust gas circulation concentration device 920, an exhaust gas treatment device 930 and an air supply device 940. The paint mist capture device 910 is arranged in the spraying room 10 and is connected to the air inlet of the exhaust gas circulation concentration device 920 through a pipeline; the exhaust gas discharge port of the exhaust gas circulation concentration device 920 is connected to the air inlet of the exhaust gas treatment device 930 through a pipeline, and the purified gas outlet of the exhaust gas circulation concentration device 920 is connected to the spraying room 10 through a pipeline; the air outlet of the air supply device 940 is connected to the spraying room 10 through a pipeline, and the air inlet of the air supply device 940 is connected to the outside atmosphere.

[0037] It should be understood that, through the above structure, the air containing paint mist in the spray room 10 will be able to be filtered for the first time through the paint mist capture device 910 to remove and recover most of the paint mist in the air, and after the air after the first filtration enters the exhaust gas circulation concentration device 920 through the pipeline, the exhaust gas circulation concentration device 920 will be able to further concentrate the paint mist in the air to achieve the second filtration of the air, and the air after the second filtration by the exhaust gas circulation concentration device 920 will be divided into two parts, one of which is the exhaust gas containing a relatively high concentration of organic solvent components (volume accounting for about 10%), and the other part is the purified air after purification (volume accounting for about 10%). The proportion is about 90%), the exhaust gas will be transported to the exhaust gas treatment device 930 through the exhaust gas discharge port and pipeline of the exhaust gas circulation concentration device 920 for treatment (for example, it will be discharged after incineration in the exhaust gas treatment device 930), and the purified air will be transported back to the spray room 10 through the purified gas outlet and pipeline of the exhaust gas circulation concentration device 920 for reuse, and the fresh air in the outside atmosphere can be replenished into the spray room 10 through the air supply device 940, so that the fresh air can be replenished while the purified air is reused, thereby effectively reducing the concentration of paint mist and organic solvents in the air in the spray room 10, thereby reducing safety hazards to ensure spraying safety.
