[0040] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0041] The embodiment provided in this application is an embodiment of a laser welding production line.

[0042] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0043] The embodiment of the present application provides a laser welding production line, including: a main production line, a bypass auxiliary line, an intelligent handling robot and a controller, such as Figure 1 shown.

[0044] The main production line at least includes a laser welding island and a quality inspection island, wherein the laser welding island includes a laser welding module, and the quality inspection island includes a quality inspection module.

[0045] A laser welding island is configured to complete the welding process on the car body.

[0046] A quality inspection island configured to perform quality inspection on the car body.

[0047] The main production line also includes an upstream island and a downstream island.

[0048] The online island is configured to automatically place the car body on the intelligent handling robot.

[0049] The intelligent handling robot carries the car body into the offline island, indicating that the laser welding task is completed.

[0050] A bypass auxiliary line is connected to the main production line in a bypass manner, wherein the bypass auxiliary line comprises a rework island, and the rework island comprises a rework module.

[0051] The bypass auxiliary line is not on the main production line, but on the bypass of the main production line. Each welded car body must pass through the main production line to complete the welding task. However, not all car bodies must pass through the bypass auxiliary line.

[0052] The laser welding production line in the embodiment of the present application includes three core islands: a laser welding island, a quality inspection island and a rework island. The core islands are independent of each other and are spaced a certain distance apart.

[0053] An intelligent handling robot is configured to carry car bodies at least on the main production line.

[0054] The intelligent mobile robot is a mobile carrier for the car body to be processed between the core islands. The controller controls the intelligent mobile robot to carry the car body into each core island as needed.

[0055] like Figure 2As shown, the controller is communicatively connected with the laser welding module, the quality inspection module, the rework module and the intelligent transport robot respectively, and is configured to determine whether the intelligent transport robot transports the vehicle body into the rework island for vehicle body rework based on the inspection results fed back by the quality inspection module.

[0056] The embodiment of the present application divides welding tasks into main production tasks and special production tasks through the main production line and the bypass auxiliary line. The controller determines whether the intelligent handling robot carries the car body into the rework island to perform the special production task of car body rework based on the inspection results fed back by the quality inspection module. As a result, the special production task is separated from the main production line, avoiding the impact of the special production task on the main production task, and improving the unit time utilization rate of the main production line.

[0057] In some specific embodiments, the controller is configured to determine whether the intelligent transport robot transports the car body into the rework island for car body rework based on the inspection results fed back by the quality inspection module, including: when the inspection results fed back by the quality inspection module include a welding qualification mark of the car body being transported by the intelligent transport robot, determining that the intelligent transport robot transports the car body through the main production line.

[0058] In this specific embodiment, when the controller receives the inspection result fed back by the quality inspection module, indicating that the quality of the car body transported by the intelligent transport robot is qualified, the controller determines that the intelligent transport robot transports the car body through the main production line without passing through the bypass auxiliary line. This shortens the distance and time for the intelligent transport robot to transport qualified car bodies, and improves the unit time utilization rate of the main production line.

[0059] In some specific embodiments, the controller is configured to determine whether the intelligent transport robot transports the car body into the rework island for car body rework based on the inspection results fed back by the quality inspection module, including: when the inspection results fed back by the quality inspection module include a rework mark of the car body being transported by the intelligent transport robot, determining that the intelligent transport robot transports the car body into the rework island for car body rework.

[0060] In this specific embodiment, when the controller receives the inspection result fed back by the quality inspection module, indicating that the quality of the body transported by the intelligent transport robot is unqualified, the controller determines that the intelligent transport robot transports the body through the bypass auxiliary line to repair the body, so that the problematic body avoids the main production line, ensuring that the qualified body can be transported normally on the main production line, thereby shortening the distance and time for the intelligent transport robot to transport the qualified body, and improving the unit time utilization rate of the main production line.

[0061] In some specific embodiments, the controller is configured to determine that the intelligent transport robot transports the vehicle body into the rework island for vehicle body rework when the inspection result fed back by the quality inspection module includes the repair mark of the vehicle body transported by the intelligent transport robot, including: when the inspection result fed back by the quality inspection module includes the identity mark of the intelligent transport robot, the repair mark and defect information of the vehicle body transported by the intelligent transport robot, determine that the intelligent transport robot transports the vehicle body into the rework island for vehicle body rework.

[0062] In this specific embodiment, the quality inspection module feeds back the identity of the intelligent transport robot, the repair mark and defect information of the vehicle body transported by the intelligent transport robot to the controller, so that the controller notifies the repair module to perform repair.

[0063] In some specific embodiments, the intelligent handling robot is configured to output its identity.

[0064] In this specific embodiment, the intelligent handling robot outputs its identity identification, and the identity identification of each intelligent handling robot can be fixed, that is, each intelligent handling robot corresponds to its identity identification one by one, and the identity identification is the permanent information of the intelligent handling robot. For example, the identity identification is represented by a QR code pasted on the surface of the intelligent handling robot; when the intelligent handling robot goes online, the identity identification can be assigned to the intelligent handling robot, and the identity identification can be displayed on the display device of the intelligent handling robot; the identity identification can also be saved in an IC card, and its identity identification can be obtained by reading the IC card, and this specific embodiment is not limited to this. The processing module in each core island can identify the intelligent handling robot through the identity identification of the intelligent handling robot, and perform targeted processing on the vehicle body transported by the intelligent handling robot.

[0065] In some specific embodiments, the repair module is configured to: obtain an identity identifier output by the intelligent handling robot; obtain defect information of the vehicle body based on the identity identifier; and repair the vehicle body based on the defect information.

[0066] In this specific embodiment, the repair module obtains the identity of the intelligent handling robot, and then obtains the defect information of the vehicle body handled by the intelligent handling robot from the controller through the identity, and then autonomously repairs the vehicle body based on the defect information. This ensures the independence of the repair module, reduces the resource occupancy rate of the controller, reduces the control burden of the controller, and improves the control efficiency of the controller on the main production line.

[0067] In some specific embodiments, the controller is further configured to: when receiving a repair completion mark fed back by the repair module, instruct the intelligent transport robot to transport the vehicle body back to the quality inspection island for vehicle body quality inspection.

[0068] In this specific embodiment, when the intelligent handling robot has completed the repair of the vehicle body, the intelligent handling robot is instructed to carry the vehicle body back to the quality inspection island to re-inspect the vehicle body quality to ensure that the vehicle body is off the production line with qualified quality. When the inspection result fed back by the quality inspection module includes the welding qualified mark of the vehicle body carried by the intelligent handling robot, the controller instructs the intelligent handling robot to carry the vehicle body off the production line.

[0069] The present application also provides a method embodiment that is based on the above embodiment. The explanation based on the same name meaning is the same as that of the above embodiment, and has the same technical effect as the above embodiment, which will not be repeated here.

[0072] Step S302: determining whether the intelligent transport robot transports the vehicle body to the repair island on the bypass auxiliary line for vehicle body repair based on the inspection result fed back by the quality inspection module.

[0073] The embodiment of the present application is applied to the above controller, and the controller obtains the inspection results fed back by the quality inspection module on the main production line, and then determines whether the intelligent handling robot carries the car body into the repair island on the bypass auxiliary line for car body repair based on the inspection results fed back by the quality inspection module. The welding tasks are divided into main production tasks and special production tasks by the main production line and the bypass auxiliary line. The controller determines whether the intelligent handling robot carries the car body into the repair island to perform the special production task of car body repair based on the inspection results fed back by the quality inspection module. As a result, the special production tasks are separated from the main production line, the influence of special production tasks on the main production tasks is avoided, and the unit time utilization rate of the main production line is improved.
