[0042] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0043] Please refer to the following Figures 1 to 5 A continuous coating flow system and a control method thereof according to an embodiment of the present invention are described.

[0044] like Figures 1 to 3 As shown, the continuous coating flow system of an embodiment of the present invention includes: a loading station 1, a continuous coating line 2, an unloading station 3 and a reflow mechanism 4. The loading station 1 and the unloading station 3 are respectively connected to the two ends of the continuous coating line 2, one end of the reflow mechanism 4 is connected to the unloading station 3, and the other end of the reflow mechanism 4 is connected to the loading station 1. The loading station 1 can install the workpiece 9 to be plated onto the coating carrier 8, the unloading station 3 can separate the coated workpiece 9 from the coating carrier 8, and the reflow mechanism 4 can transport the separated coating carrier 8 to the loading station 1.

[0045] According to the continuous coating circulation system of the embodiment of the present invention, since the loading station 1 and the unloading station 3 are respectively connected to the two ends of the continuous coating line 2, the loading station 1 and the unloading station 3 can be separated by a certain distance so that the loading process and the unloading process do not affect each other, so as to adapt to the fast-beat coating process. In addition, since one end of the reflux mechanism 4 is connected to the unloading station 3 and the other end of the reflux mechanism 4 is connected to the loading station 1, the reflux mechanism 4 can transport the separated coating carrier 8 to the loading station 1, thereby the unloaded coating carrier 8 can be automatically circulated by the reflux mechanism 4, saving manpower and being conducive to improving the production efficiency of the continuous coating circulation system.

[0046] It should be noted that the continuous coating line 2 is a continuous coating device. The continuous coating device has high efficiency, but requires more operating conditions to assist operators, the maintenance cycle of the coating carrier 8 is greatly shortened, and the use of the equipment also requires high labor costs. In order to liberate manual labor as much as possible, improve work efficiency, and reduce production costs, the continuous coating flow system of the present invention is developed.

[0047] The continuous coating transfer system of an embodiment of the present invention adopts an automated reflux mechanism 4, which can automatically transfer the coating carrier 8 to solve the problem of manually transferring the coating carrier 8 frequently from the unloading chamber (unloading station 3) to the loading chamber (loading station 1), thereby improving the efficiency of coating and greatly reducing the workload of operators.

[0048] Alternatively, if Figure 1 and Figure 3 As shown, the continuous coating circulation system further includes a cleaning station 5, which is arranged on the extension path of the reflux mechanism 4. The reflux mechanism 4 can transport the separated coating carrier 8 to the cleaning station 5 for cleaning, and transport the cleaned coating carrier 8 to the loading station 1. It can be understood that the reflux mechanism 4 can be divided into two sections, one section of the reflux mechanism 4 is used to automatically transfer the separated coating carrier 8 (i.e., the empty coating carrier 8) to the cleaning station 5, and the other section of the reflux mechanism 4 is used to automatically transfer the cleaned coating carrier 8 to the loading station 1. The continuous coating circulation system of the embodiment of the present invention can greatly increase the service life of the coating carrier 8 and reduce the number of maintenance times of the coating carrier 8 by setting the cleaning station 5, which is conducive to improving the production capacity of the continuous coating circulation system.

[0049] The following is a brief description of the working process of the continuous coating flow system of the embodiment of the present invention:

[0050] At the loading station 1, the workpiece 9 to be plated is mounted on the coating carrier 8 by a manipulator or a dedicated mounting device;

[0051] The loaded coating carrier 8 is transported to the feed port of the continuous coating line 2, and the continuous coating line 2 coats the workpiece 9, and the workpiece 9 flows out from the discharge port of the continuous coating line 2 to the unloading station 3;

[0052] At the unloading station 3, the coated workpiece 9 is separated from the coating carrier 8 by a manipulator or a dedicated hanging device, and the separated coated workpiece 9 flows out to the unloading station 3;

[0053] The separated coating carrier 8 (ie, the empty coating carrier 8) is transported to the cleaning station 5 through the reflux mechanism 4 for cleaning and dust removal. After cleaning, the coating carrier 8 is then transported to the loading station 1 through the reflux mechanism 4 for the next cycle.

[0054] like Figure 3 and Figure 4 As shown, the cleaning station 5 includes a cover body 51 and a cleaning brush assembly 52. ​​The cleaning brush assembly 52 is disposed in the cover body 51. The reflow mechanism 4 includes a transmission chain assembly 41. The transmission chain assembly 41 passes through the cover body 51. The transmission chain assembly 41 is used to transport the coating carrier 8 along the extension path of the reflow mechanism 4. When the coating carrier 8 passes through the cover body 51, the cleaning brush assembly 52 can clean the surface of the coating carrier 8.

[0055] It is understandable that the transmission chain assembly 41 can automatically transfer the unloaded coating carrier 8. Since the transmission chain assembly 41 passes through the cover 51, the unloaded coating carrier 8 transferred by the reflux mechanism 4 can be transported into the cover 51 so that the cleaning station 5 can clean the unloaded coating carrier 8. Since the cleaning brush assembly 52 can clean the surface of the coating carrier 8 when the coating carrier 8 passes through the cover 51, the coating on the coating carrier 8 can be polished and removed by the cleaning brush assembly 52 to automatically maintain the coating carrier 8, thereby greatly saving labor costs and being able to adapt to fast-paced coating processes.

[0056] In one example, at least two groups of cleaning brush assemblies 52 are provided, and the two groups of cleaning brush assemblies 52 are respectively arranged on both sides of the thickness direction of the coating carrier 8. It can be understood that the coating carrier 8 is placed in a vertical position during coating to meet the coating process of the continuous coating line 2. When the reflux mechanism 4 is transporting the coating carrier 8, the coating carrier 8 still maintains a vertical position. Therefore, by arranging the cleaning brush assemblies 52 on both sides of the thickness direction of the coating carrier 8, the surfaces on both sides of the coating carrier 8 can be cleaned simultaneously to improve the cleaning efficiency of the coating carrier 8 and save the cleaning time of the coating carrier 8.

[0057] Alternatively, if Figure 4 As shown, the cleaning brush assembly 52 includes a driving motor 522 and a cleaning brush 521, the driving motor 522 is in transmission connection with the cleaning brush 521, the bristles of the cleaning brush 521 are in contact with the coating carrier 8, and the cleaning brush 521 extends along the height direction of the coating carrier 8. Since the cleaning brush 521 extends along the height direction of the coating carrier 8, the entire surface of the coating carrier 8 can be cleaned, which is beneficial to improving the cleaning effect and cleaning efficiency of the coating carrier 8.

[0058] For example, each group of cleaning brush assemblies 52 includes a plurality of cleaning brushes 521 , and the plurality of cleaning brushes 521 are arranged at intervals along the flow direction of the coating carrier 8 to further improve the cleaning effect and cleaning efficiency of the coating carrier 8 .

[0059] In one example, if Figure 3 and Figure 5As shown, the reflux mechanism 4 includes a plurality of frames 42 arranged in sequence, each frame 42 is provided with a portion of a transmission chain assembly 41, and the coating carrier 8 is sequentially transmitted through the plurality of frames 42. For example, the transmission chain assembly 41 is provided on the upper side of the frame 42 and is transmission-connected to the coating carrier 8, and a guide groove 421 for supporting and guiding the coating carrier 8 is provided on the lower side of the frame 42.

[0060] In some embodiments, Figure 3 and Figure 4 As shown, the cleaning station 5 further includes a dust removal fan 53, which has a dust suction port 531, and the dust suction port 531 is connected to the chamber surrounded by the cover body 51. It can be understood that the chamber surrounded by the cover body 51 is closed to prevent the dust generated by the cleaning brush 521 grinding the coating carrier 8 from overflowing, and in order to prevent the cleaned coating carrier 8 from being contaminated by the grinding dust, the dust in the cover body 51 can be removed by the dust removal fan 53 to improve the cleaning effect of the coating carrier 8.

[0061] Alternatively, if Figure 3 and Figure 4 As shown, the dust removal fan 53 is arranged in the chamber surrounded by the cover body 51, and there are at least two dust suction ports 531, which are arranged at intervals along the extension path of the reflux mechanism 4. Since the two dust suction ports 531 are arranged at intervals along the extension path of the reflux mechanism 4, the dust removal efficiency of the dust removal fan 53 can be improved. On the other hand, since the dust removal fan 53 is installed in the cover body 51, the compactness of the structure of the cleaning station 5 can be improved.

[0062] For example, the cleaning station 5 further includes a dust box 54. The dust box 54 and the dust removal fan 53 are both arranged in a chamber surrounded by the cover body 51. The dust removal fan 53 has a dust outlet, which is connected to the dust box 54. It can be understood that the dust sucked by the dust outlet fan can enter the dust box 54, and the operator can regularly clean the dust in the dust box 54 to reduce the maintenance cycle of the cleaning station 5 and save manpower.

[0063] In some embodiments, Figure 1 As shown, the continuous coating circulation system further includes a feed conveyor 61, one end of which is connected to the loading station 1, and the other end of which is connected to the continuous coating line 2. The feed conveyor 61 is used to transport the coating carrier 8 carrying the workpiece 9 to be plated to the continuous coating line 2. It can be understood that the coating carrier 8 carrying the workpiece 9 to be plated can be automatically transmitted to the feed port in the continuous coating line 2 through the feed conveyor 61, so as to realize the automatic feeding function of the continuous coating circulation system and save manpower.

[0064] Furthermore, if Figure 1As shown, the continuous coating circulation system further includes a discharge conveyor 62, one end of which is connected to the continuous coating line 2, and the other end of which is connected to the unloading station 3. The discharge conveyor 62 is used to convey the coated workpiece 9 and the coating carrier 8 to the discharge station. It can be understood that the coating carrier 8 carrying the coated workpiece 9 can be automatically conveyed from the discharge port in the continuous coating line 2 to the unloading station 3 through the discharge conveyor 62, so as to realize the automatic discharge function of the continuous coating circulation system and save manpower.

[0065] The continuous coating flow system of the embodiment of the present invention can realize automatic feeding and automatic discharging of the continuous coating line 2 by setting a feeding conveyor 61 and a discharging conveyor 62. Compared with the solution of manually pushing the material, it can save manpower and adapt to the fast-beat coating process.

[0066] In some embodiments, Figure 1 As shown, the continuous coating flow system also includes a first translation station 71, which is used to transport the separated coating carrier 8. The unloading station 3 is connected to the reflow mechanism 4 through the first translation station 71. The extension direction of the first translation station 71 is perpendicular to the extension direction of the continuous coating line 2, and the extension direction of the reflow mechanism 4 is consistent with the extension direction of the continuous coating line 2. It can be understood that the first translation station 71 can translate the vertical coating carrier 8 onto the reflow mechanism 4, and then reflow through the reflow mechanism 4. The continuous coating flow system of the embodiment of the present invention can realize the automatic circulation of the vertical coating carrier 8 by setting the first translation station 71, saving manpower.

[0067] On the other hand, compared with the solution in which the reflow mechanism 4 is directly connected to the unloading station 3, the present application can shorten the extension path of the reflow mechanism 4. It can be understood that when the reflow mechanism 4 is directly connected to the unloading station 3, in order to realize the transportation of the vertical coating carrier 8, the connection position of the reflow mechanism 4 and the unloading station 3 needs to be designed as a runway-shaped turn, while the continuous coating flow system of the embodiment of the present invention makes the extension direction of the first translation station 71 perpendicular to the extension direction of the continuous coating line 2, and the extension direction of the reflow mechanism 4 is consistent with the extension direction of the continuous coating line 2. The overall layout length of the continuous coating flow system can be shortened, and the occupied space of the continuous coating flow system can be reduced.

[0068] Alternatively, if Figure 1 As shown, the continuous coating flow system also includes a second translation station 72. The loading station 1 is connected to the reflow mechanism 4 through the second translation station 72. The second translation station 72 is used to transport the cleaned coating carrier 8. The extension direction of the second translation station 72 is perpendicular to the extension direction of the continuous coating line 2. The extension direction of the reflow mechanism 4 is consistent with the extension direction of the continuous coating line 2.

[0069] It is understandable that the second translation station 72 can translate the vertical coating carrier 8 from the rotary mechanism to the loading station 1. The continuous coating flow system of the embodiment of the present invention can realize the automatic flow of the vertical coating carrier 8 and save manpower by setting the second translation station 72.

[0070] On the other hand, compared with the solution in which the reflow mechanism 4 is directly connected to the loading station 1, the present application can shorten the extension path of the reflow mechanism 4. It can be understood that when the reflow mechanism 4 is directly connected to the loading station 1, in order to realize the transportation of the vertical coating carrier 8, the connection position of the reflow mechanism 4 and the loading station 1 needs to be designed as a runway-shaped turn, while the continuous coating flow system of the embodiment of the present invention makes the extension direction of the second translation station 72 perpendicular to the extension direction of the continuous coating line 2, and the extension direction of the reflow mechanism 4 is consistent with the extension direction of the continuous coating line 2. The overall layout length of the continuous coating flow system can be shortened, and the occupied space of the continuous coating flow system can be reduced.

[0071] In some embodiments, the loading station 1 includes a first appearance inspection workbench, a first NG platform and a loading platform. The first NG platform and the loading platform are both connected to the first appearance inspection workbench. The first appearance inspection workbench is used to detect whether the workpiece 9 to be plated meets the coating requirements. When the workpiece 9 to be plated does not meet the coating requirements, the first appearance inspection workbench can transport the workpiece 9 to be plated to the first NG platform. When the workpiece 9 to be plated meets the coating requirements, the first appearance inspection workbench can transport the workpiece 9 to be plated to the loading platform for installation on the coating carrier 8.

[0072] It is understandable that "NG" means "unqualified". When the first appearance inspection workbench detects whether the workpiece 9 to be plated meets the coating requirements, the appearance of the workpiece 9 to be plated can be automatically inspected by machine vision automatic recognition, or by manual recognition.

[0073] When the workpiece 9 to be plated does not meet the coating requirements, the first appearance inspection workbench can transport the workpiece 9 to the first NG platform to prevent defective products from flowing into the next coating process. When the workpiece 9 to be plated meets the coating requirements, the first appearance inspection workbench can transport the workpiece 9 to the loading platform to be installed on the coating carrier 8 for the next coating process.

[0074] Optionally, the unloading station 3 includes a second appearance inspection workbench, a second NG platform and an unloading platform. The second NG platform and the unloading platform are both connected to the second appearance inspection workbench. The second appearance inspection workbench is used to detect whether the coated workpiece 9 meets the coating requirements. When the coated workpiece 9 does not meet the coating requirements, the second appearance inspection workbench can transport the coated workpiece 9 to the second NG platform. When the coated workpiece 9 meets the coating requirements, the second appearance inspection workbench can transport the coated workpiece 9 to the unloading platform.

[0075] It is understandable that "NG" means "unqualified". When the second appearance inspection workbench detects whether the workpiece 9 to be plated meets the coating requirements, the appearance of the workpiece 9 to be plated can be automatically inspected by machine vision automatic recognition, or by manual recognition.

[0076] When the plated workpiece 9 does not meet the requirements of the coating (i.e., the coating is defective or the appearance is abnormal), the second appearance inspection workbench can transport the plated workpiece 9 to the second NG platform to prevent defective products from flowing into the unloading platform. When the plated workpiece 9 meets the requirements of the coating, the second appearance inspection workbench can transport the plated workpiece 9 to the unloading platform to discharge the finished product.

[0077] like Figures 1 to 5 As shown, the control method of continuous coating of an embodiment of the present invention adopts the continuous coating flow system of the present invention, and the control method of continuous coating includes the following steps:

[0078] S1: Checking whether the workpiece 9 to be plated meets the coating requirements at the loading station 1, and when the workpiece 9 to be plated meets the coating requirements, installing the workpiece 9 to be plated on the coating carrier 8;

[0079] S2: docking the coating carrier 8 with the workpiece 9 to be coated with the feed conveyor 61 and conveying it to the continuous coating line 2;

[0080] S3: The workpiece 9 to be plated is subjected to a coating process on the continuous coating line 2 according to a preset process;

[0081] S4: After the coating is completed, the workpiece 9 is transported to the unloading station 3 through the unloading conveyor 62;

[0082] S5: separating the workpiece 9 after coating from the coating carrier 8 at the unloading station 3;

[0083] S6: transporting the separated coating carrier 8 to the cleaning station 5 through the reflux mechanism 4;

[0084] S7: Cleaning the separated coating carrier 8 through the cleaning station 5;

[0085] S8: The cleaned coating carrier 8 is reflowed to the loading station 1 through the reflow mechanism 4 .

[0086] According to the control method of continuous coating of the embodiment of the present invention, since the loading station 1 and the unloading station 3 are respectively connected to the two ends of the continuous coating line 2, the loading station 1 and the unloading station 3 can be separated by a certain distance so that the loading process and the unloading process do not affect each other, so as to adapt to the fast-beat coating process. In addition, the reflux mechanism 4 and the cleaning station 5 can automatically circulate and clean the unloaded coating carrier 8, which can greatly shorten the maintenance cycle of the coating carrier 8, save manpower, and help improve the production efficiency of the continuous coating circulation system.

[0087] In summary, the continuous coating flow system and control method of the embodiments of the present invention have at least the following technical effects:

[0088] 1. The loading station 1 and unloading station 3 of the continuous coating circulation system of the embodiment of the present invention are respectively located at the loading port and unloading port of the continuous coating line 2, which solves the problem of frequent loading and unloading of operators, especially can adapt to the fast-beat coating process. At the same time, the continuous coating circulation system can automatically detect the workpiece 9 in the loading stage and the unloading stage to ensure the quality of the workpiece 9 to be plated / completed coating, improve the quality inspection process of the coating process, and reduce the workload of operators.

[0089] 2. The coating carrier of the continuous coating flow system of the embodiment of the present invention can be automatically closed and circulated, which solves the problem of manually transferring the coating carrier 8 frequently from the unloading station 3 to the loading station 1, improves the efficiency of coating, and greatly reduces the workload of operators.

[0090] 3. The continuous coating circulation system of the embodiment of the present invention can greatly increase the service life of the coating carrier 8 and reduce the number of frequent maintenance of the coating carrier 8 by setting up a cleaning station 5, which is beneficial to improving the production capacity of the continuous coating circulation system.
