[0021] Figure 4 This is a flowchart illustrating a vehicle painting method according to an exemplary embodiment. Detailed Implementation
[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0023] Vehicles require painting during production, a systematic process that necessitates the advance preparation of the necessary paint. This involves loading the paint from the mixing system into the painting robot. Different vehicle models require different colors, but the mixing system has a limited capacity. When a color not available in the mixing system needs to be applied, the existing paint must be cleaned before new paint is added. This process is time-consuming, leading to production interruptions and impacting the painting progress.
[0024] As mentioned earlier, different car models require different colors. Some models require large quantities of color, which is what most cars need, while others require small quantities, which is what only a few cars need. If the paint mixing system originally contained a large quantity of color, and a small quantity is needed, the large quantity of color must be cleaned out before the small quantity is added. After the vehicles requiring small quantities are finished, many more vehicles still needing large quantities are waiting to be painted. Therefore, the paint mixing system needs to be cleaned again, the small quantity of color paint removed, and the large quantity of color paint added. This back-and-forth color-changing process is not only time-consuming, but each cleaning consumes over 300 liters of cleaning solvent, making repeated cleanings even more costly.
[0025] To address the aforementioned problems, this disclosure provides a vehicle painting system. Please refer to [link / reference]. Figure 1 The vehicle painting system 100 includes a control device 110, a painting robot 120, and multiple paint mixing devices 130. The painting robot 120 is communicatively connected to the control device 110, and the painting robot 120 is connected to each of the multiple paint mixing devices 130.
[0026] The plurality of paint mixing devices 130 are configured to hold paints of different colors.
[0027] To ensure the visual effect and sense of layering in the paint spraying, multiple layers of paint may be required for the same vehicle, or different vehicle models may have different color requirements. Therefore, multiple colors of paint are needed on the painting production line. In this embodiment, multiple paint mixing devices 130 are used to hold different colors of paint to adapt to vehicles with various color requirements.
[0028] The painting robot 120 has multiple color-changing valves on its robotic arm, which are connected to multiple paint mixing devices. According to the color requirements of the vehicle, the robot loads the corresponding color of paint from the corresponding paint mixing device for painting.
[0029] Optionally, the robotic arm of the painting robot 120 is equipped with 24 color-changing valves.
[0030] The control device 110 is configured to determine a target paint mixing device from the plurality of paint mixing devices according to the color to be painted on the target vehicle, and to control the painting robot to use the target paint mixing device to paint the target vehicle, wherein the target paint mixing device is used to hold the paint of the color to be painted.
[0031] It is understood that the target vehicle is the vehicle to be painted. The control device 110 obtains the paint color to be painted on the target vehicle. For example, the control device 110 obtains the order information corresponding to the target vehicle, which includes the vehicle model, configuration, and paint color to be painted. The control device 110 obtains the paint color to be painted based on the order information. The control device 110 selects a target paint mixing device containing the paint of the desired color from multiple paint mixing devices. The control robot opens the color-changing valve connected to the target paint mixing device, allowing the paint of the desired color in the target paint mixing device to be sprayed onto the surface of the target vehicle through the robot's color-changing valve. For example, the control device 110 sends the order information to the control robot. The control robot, based on the paint color to be painted in the order information, opens the color-changing valve connected to the target paint mixing device and uses the paint of the desired color in the target paint mixing device for painting.
[0032] Alternatively, the control device may be a graphics processing unit (GPU), a field programmable gate array (FPGA), a system on chip (SOC), an application specific integrated circuit (ASIC), or a combination thereof.
[0033] The vehicle painting system provided in this embodiment includes multiple paint mixing devices configured to hold different colors of paint. A control device is configured to determine the target paint mixing device containing the desired paint color from among the multiple mixing devices based on the target vehicle's desired paint color, and then control the painting robot to use the target paint mixing device to paint the target vehicle. Because multiple paint mixing devices are configured to hold different colors of paint, the corresponding mixing device is used directly during vehicle painting, avoiding frequent cleaning and color-changing operations, reducing color-changing time, and improving painting efficiency. Furthermore, since the paint mixing devices in this embodiment do not require color changing, incomplete cleaning of the mixing devices avoids paint color mixing, which could affect the painting effect.
[0034] For example, this embodiment uses two paint mixing systems as an example. Please refer to [link / reference]. Figure 2 The plurality of paint mixing devices include a first paint mixing device 131 for holding paint of a first color and a second paint mixing device 132 for holding paint of a second color, wherein the first color is the color corresponding to vehicles that account for a proportion greater than or equal to a preset proportion among all vehicles to be painted, including the target vehicle, and the second color is the color corresponding to vehicles that account for a proportion less than the preset proportion among all vehicles to be painted.
[0035] The colors of the vehicles to be painted can be statistically analyzed to determine the proportion of each color. Based on the proportion, the correspondence between the color to be painted and the first color, or the correspondence between the color to be painted and the second color, can be set in the control device. The correspondence can be shown in Table 1.
[0036] Table 1
[0037]
[0038] It should be noted that Table 1 is only an example of the correspondence between the color to be sprayed and the first or second color. This relationship is not fixed and can be changed to adapt to production needs. For example, when color 4 is sprayed in large quantities, color 4 can be the first color, and when color 1 is sprayed in small quantities, color 1 can also be the second color.
[0039] Optionally, the first paint mixing device 131 can be a conventional paint supply system, which holds large quantities of paint of a particular color. It's easy to understand that most vehicles require paint supplied by a conventional paint supply system. The second paint mixing device 132 can be a quick-change system, which holds small quantities of paint of a particular color. These small quantities can be customized colors. It's easy to understand that fewer vehicles require paint supplied by a quick-change system. The quick-change system is a rollerball quick-change system. This system can quickly clean and change paint, and during cleaning, the solvent consumption of the quick-change system is approximately one-twentieth to one-tenth that of a conventional paint supply system, and the cleaning time can be reduced to one hour.
[0040] In one embodiment, the control device is configured to determine the first paint mixing device 131 as the target paint mixing device when the color to be sprayed belongs to the first color, or to determine the second paint mixing device 132 as the target paint mixing device when the color to be sprayed belongs to the second color.
[0041] For example, if the color to be sprayed is color 1, the control device looks up the information in Table 1 to determine that color 1 corresponds to the first color, and then determines the first paint mixing device as the target paint mixing device. For example, if the color to be sprayed is color 4, the control device looks up the information in Table 1 to determine that color 4 corresponds to the second color, and then determines the second paint mixing device as the target paint mixing device.
[0042] In another embodiment, the control device is configured to determine the paint mixing device corresponding to the color to be sprayed as the target paint mixing device based on the color to be sprayed. For example, the first paint mixing device holds black paint, and the second paint mixing device holds purple paint. When the color to be sprayed is purple, the second paint mixing device holding purple paint is determined to be the target paint mixing device.
[0043] For example, the target paint mixing device is the second paint mixing device, which is communicatively connected to the control device.
[0044] The second paint mixing device is configured to detect whether there is paint of the color to be sprayed in the second paint mixing device, obtain the detection result and send it to the control device.
[0045] It is easy to understand that the test results indicate whether there is paint of the color to be sprayed in the paint mixing device.
[0046] In one embodiment, a detection element is installed in the second paint mixing device. The second paint mixing device performs detection through the detection element to obtain a detection result. As one approach, the detection element may include a flow meter, which is installed inside the paint transport pipe of the second paint mixing device. The flow meter detects the flow rate within the pipe. If the flow meter shows a flow rate, a detection result indicating that there is paint of the color to be sprayed is obtained. If the flow meter shows no flow rate, a detection result indicating that there is no paint of the color to be sprayed is obtained.
[0047] Alternatively, the detection unit may include a pressure sensor, and the second paint mixing device may also include a paint bucket for holding the paint of the color to be sprayed, with the pressure sensor installed inside the paint bucket and configured to detect the pressure value inside the paint bucket, and obtain the detection result based on the pressure value.
[0048] The control device is further configured to receive the detection result, and after the detection result indicates that there is paint of the color to be sprayed in the second paint mixing device, control the painting robot to use the paint of the color to be sprayed in the second paint mixing device to spray the target vehicle.
[0049] Optionally, the vehicle painting system further includes a transport device connected to the control device.
[0050] The transport equipment is configured to transport the target vehicle on the painting production line.
[0051] The target vehicle's painting is completed on a painting production line, which is sequentially divided into an intermediate coat production line, a color separation area, and a topcoat production line. The intermediate coat production line applies the intermediate coating. The color separation area can be used to accommodate vehicles or to apply fine color separation tape, masking materials, etc. The topcoat production line applies the vehicle's topcoat, and painting robots are installed on this line. There is a certain distance between the different production lines. The target vehicle can be placed on a transport device and moved along the painting production line to facilitate the various painting operations. Optionally, the transport device can be a conveyor belt.
[0052] Since the second paint mixing unit is configured to hold a second color of paint with a low probability of use, and there may be no paint injected into the second paint mixing unit, or the injected paint may be exhausted and no paint may be detected in the second paint mixing unit, the control device is configured to control the transport equipment to stop the target vehicle in the color separation area on the painting production line after the detection result indicates that there is no paint of the color to be sprayed in the second paint mixing unit.
[0053] Since the second paint mixing unit is used to hold small batches of paint of a particular color, if there are not many vehicles requiring that paint, or if the paint in the unit has been exhausted, it may be that the second paint mixing unit is empty. In this case, the transport equipment moves the target vehicle to the color separation area to wait. The operator can then add the paint of the desired color to the second paint mixing unit and wait for the paint in the second paint mixing unit to be successfully mixed before controlling the transport equipment to move the target vehicle from the color separation area to the topcoat production line for painting. Optionally, paint can be added to the paint bucket of the second paint mixing unit, and the paint in the bucket can be stirred for a preset time to confirm that the paint has been successfully mixed; for example, the preset time could be 30 minutes.
[0054] The control device is configured to, after the detection result indicates that there is paint of the color to be sprayed in the second paint mixing device, control the transport equipment to transport the target vehicle to the topcoat production line of the spraying production line, and control the spraying robot on the topcoat production line to spray the target vehicle with the paint of the color to be sprayed contained in the second paint mixing device.
[0055] Combination Figure 2 When the control device confirms that the first paint mixing device is the target paint mixing device, if the second paint mixing device is found to contain paint of the second color, the first control device controls the spraying robot to use the first paint mixing device for spraying. As a way, the second paint mixing device can be left unstirred to save energy consumption.
[0056] As another approach, to ensure paint spraying quality, when using the first paint mixing system, the paint can be stirred at a first frequency using a stirring pump within the first system, while simultaneously stirred at a second frequency using a stirring pump within the second system. The first frequency is higher than the second frequency. In this method, stirring the paint in the second paint mixing system at a lower frequency prevents the settling of solid particles, which could lead to uneven paint color and affect the spraying effect. When subsequent vehicles require painting using the second paint mixing system, the already stirred paint can be directly loaded for spraying, thus improving spraying production efficiency.
[0057] Optionally, the control device includes a prompting unit.
[0058] The prompting unit is configured to prompt the user to add the paint of the color to be sprayed into the second paint mixing device.
[0059] In one embodiment, the prompting unit includes a microphone that provides voice prompts for the color to be sprayed, and the operator adds paint to the second paint mixing device according to the voice prompts.
[0060] In another embodiment, the prompting unit includes a display device that displays the color to be sprayed, and the operator adds paint to the second paint mixing device according to the displayed content.
[0061] For example, if there is more than one target vehicle to be painted on the painting production line, the display device can provide a list, as shown in Table 2:
[0062] Table 2
[0063]
[0064] The operator checks the paint in the second paint mixing unit according to Table 2, or injects the corresponding paint into the second paint mixing unit.
[0065] Optionally, the vehicle painting system further includes an identification device, which is communicatively connected to the control device.
[0066] The identification device is configured to acquire the color to be painted on the target vehicle.
[0067] The control device is also configured to obtain the color to be sprayed from the identification device.
[0068] In one embodiment, the identification device includes a scanning unit and a reading / writing unit, wherein the scanning unit and the control device are respectively connected to the reading / writing unit.
[0069] The identification device acquires the color to be painted by scanning the target vehicle to obtain its vehicle identification. For example, the scanning unit is configured to scan a graphic code on the target vehicle to obtain the vehicle identification carried by the graphic code. The graphic code may be a QR code, barcode, etc.
[0070] The read / write unit is configured to send the vehicle identifier to the control device. Optionally, the read / write unit can be an RFID (radio frequency identification) read / write station.
[0071] The read / write unit is also configured to acquire the color to be painted based on feedback from the control device of the vehicle identification.
[0072] Optionally, after receiving the vehicle identification, the control device obtains the color to be painted corresponding to the vehicle identification based on the correspondence between the vehicle identification and the color to be painted, and feeds back the color to be painted to the read / write unit.
[0073] In one embodiment, the identification device further includes a tracking chip (tag) connected to the read / write unit.
[0074] The read / write unit is also configured to store the color to be sprayed into the tracking chip.
[0075] The control device is also configured to obtain the color to be sprayed from the tracking chip via the read / write unit.
[0076] Optionally, after the target vehicle is painted, the information corresponding to the target vehicle can be deleted. For example, the tracking chip is configured to delete the painting information after the painting robot finishes painting.
[0077] The control device is also configured to delete the spraying information after the spraying robot finishes spraying.
[0078] For example, continuing with Table 2, after the painting of vehicle model 5 corresponding to serial number 1 is completed, the information corresponding to that vehicle can be deleted from the list displayed on the display device. Then the content displayed on the display device is as shown in Table 3:
[0079] Table 3
[0080]
[0081] As shown above, compared to Table 2, after the painting of model 5 has been completed, Table 3 no longer displays information related to model 5.
[0082] Optionally, the control device is configured to control the painting robot to paint the target vehicle with the paint of the desired color contained in the target paint mixing device when the target vehicle is located at a preset position on the topcoat production line in the painting production line.
[0083] The preset position is the position where the painting robot on the topcoat production line can perform painting operations. When the transport equipment transports the target vehicle to the preset position, the control device controls the painting robot to use the paint in the target paint mixing device to paint the target vehicle.
[0084] In one implementation, the number of identification devices can be multiple to monitor the vehicle's status at various points on the painting production line. For an example, please refer to... Figure 3 A first identification device 141 is installed at the entrance of the intermediate coating production line on the spraying production line, a second identification device 142 is installed at the entrance of the color separation zone, and a third identification device 143 is installed at the exit of the color separation zone. A fourth identification device 144 is installed at the entrance of the topcoat production line.
[0085] When the target vehicle arrives at the entrance of the intermediate coating production line, the first identification device 141 obtains the order information of the target vehicle and sends the order information to the control device, which only displays the order information.
[0086] When the second identification device 142 detects that the target vehicle has arrived at the entrance of the color separation zone, it sends an order to the control device according to a similar process described above. The control device's audible and visual alarm sounds an alarm and displays the order information through the control device's display device, requesting the operator to load the paint.
[0087] When the third identification device 143 detects that the target vehicle has arrived at the exit of the color separation area, it sends order information to the control device according to a similar process described above. The control device compares the color to be painted shown in the order information with the paint color already contained in the target paint mixing device. If the two colors match, the control device controls the target vehicle to enter the topcoat production line for painting. If the two colors do not match, the control device controls the target vehicle to wait for painting in the color separation area.
[0088] After the fourth identification device 144 detects that the target vehicle has arrived at the entrance of the topcoat production line, it sends an order information control device according to a similar process described above. If the control device confirms that the target vehicle has been painted, it deletes the order information of the target vehicle stored on it.
[0089] Based on the same concept, this disclosure provides a vehicle painting method, applied to Figure 1 For vehicle painting system 100, please refer to [link / reference]. Figure 4 The method includes the following steps:
[0090] Step S101: The control device sets the first color and the second color.
[0091] Step S102: The first detection device detects the order information.
[0092] Step S103: The control device receives the order information.
[0093] Step S104: The control device compares the color rules according to the order information.
[0094] Step S105: Determine whether it belongs to the second color.
[0095] If yes, the process proceeds to step S107; otherwise, the process proceeds to step S106.
[0096] Step S106: Determine the first paint mixing device as the target paint mixing device.
[0097] Step S107: Determine the second paint mixing device as the target paint mixing device.
[0098] Step S108: The alarm sounds, and the display device shows the order information.
[0099] Step S109: The operator confirms the color.
[0100] Step S110: Determine whether it belongs to the second color.
[0101] If not, the process proceeds to step S111; if yes, the process proceeds to step S112.
[0102] Step S111: Determine the first paint mixing device as the target paint mixing device.
[0103] Step S112: The alarm sounds, and the display device shows the order information.
[0104] Step S113: Determine whether it belongs to the second color.
[0105] If not, the process proceeds to step S114; if yes, the process proceeds to step S115.
[0106] Step S114: The target vehicle stops in the color-separated area.
[0107] Step S115: Control the painting robot to paint the target vehicle.
[0108] Step S116: Delete order information.
