[0004] In view of the above technical problems, the utility model discloses a coding system for off-line pneumatic coding of a casting machine hub and laser coding after heat treatment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A coding system for tracing includes a pneumatic coding system and a laser coding system.

[0007] Pneumatic coding system: The pneumatic coding system is arranged downstream of the casting machine, including a frame, a pneumatic coding conveying roller arranged on the frame, and a ball center mechanism is arranged above the pneumatic coding conveying roller; a one-dimensional code scanning device is arranged on the side of the pneumatic coding conveying roller, and a pneumatic coding machine is arranged near the one-dimensional code scanning device.

[0012] Furthermore, the laser coding ball center mechanism includes a laser coding ball center clamping mechanism above the laser coding conveying roller, a laser coding servo lifting mechanism that controls the up and down movement of the laser coding ball center clamping mechanism, and a laser coding servo rotating mechanism that controls the rotation of the laser coding ball center clamping mechanism.

[0016] The working process of the coding system for tracing of the utility model is as follows: the wheel hub of the casting machine first arrives at the pneumatic coding machine, and the pneumatic coding performs a ball center operation on the wheel hub. After the ball center operation is completed, the lifting servo mechanism lifts the wheel hub to a certain height. After the lifting is completed, the rotating mechanism rotates the wheel hub to a specific angle and triggers the one-dimensional code scanning function at the same time. The rotation angle ensures that the one-dimensional code can be completely scanned. After the rotation is completed, the one-dimensional code scanning is also completed at the same time. The PLC controller rotates the wheel hub to the pneumatic coding position according to the scanned one-dimensional code content. The PLC controller controls the pneumatic coding machine to perform pneumatic coding according to the obtained pneumatic code content. After the pneumatic coding is completed, the wheel hub continues to be transported to the subsequent workstation by the pneumatic coding conveying roller for operation. After the wheel hub comes out of the heat treatment furnace, it will pass through the laser coding equipment. The laser coding system also performs ball center operation, lifting and one-dimensional code scanning. The PLC controller controls the laser coding machine to engrave the two-dimensional code content on the wheel hub according to the scanned one-dimensional code. After the coding is completed, the code is scanned to confirm the coding effect.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 The invention relates to a pneumatic coding device for a coding system used for tracing according to an embodiment of the utility model.

[0019] Figure 2 The invention relates to a laser coding device for a coding system used for tracing in an embodiment of the utility model. DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings.

[0021] The coding system for tracing of this embodiment is a pneumatic coding system placed at the offline position of the casting machine wheel hub. The pneumatic coding system reads the one-dimensional code information precast on the wheel hub and feeds this one-dimensional code information back to the factory information system. The pneumatic coding machine obtains the casting information from the factory information system and uses a dot-pin pneumatic coding device to engrave a unique pneumatic code on the wheel hub. A laser coding system for engraving a laser two-dimensional code is placed at the heat treatment outlet. When the heat-treated wheel hub passes through the laser coding machine 11, the laser coding system scans the one-dimensional code precast on the wheel hub and locates the position of the pneumatic code through this one-dimensional code, and then scans the content of the pneumatic code and feeds it back to the factory information system. The factory information system generates two-dimensional code information through this pneumatic code content and feeds it back to the coding device. The laser coding machine 11 engraves this two-dimensional code content at a preset position. This two-dimensional code will not be cleared during the subsequent processing process and can be used for subsequent traceability queries.

[0022] Pneumatic coding: The wheel hub is fed into the equipment by the conveyor roller 6. After the wheel hub runs to the center of the roller, the pneumatic coding conveyor roller 6 stops moving. At this time, the center clamping mechanism 3 centers the wheel hub and clamps the wheel hub. After the wheel hub is clamped, the servo lifting device 1 lifts the wheel hub to a certain height. After the lifting is completed, the servo rotating mechanism 2 drives the wheel hub to rotate to a certain angle. This angle ensures that the one-dimensional code scanning device can completely scan the one-dimensional code on the wheel hub. When the rotating mechanism starts to rotate, the PLC sends a signal to the one-dimensional code scanning device 5 to start scanning. When the rotating mechanism rotates to the set angle, the one-dimensional code scanning device 5 sends the scanned one-dimensional code content and the position of the one-dimensional code to the PLC. The PLC calls the formula number preset in the PLC according to the one-dimensional code content. According to the position of the current one-dimensional code, the rotating mechanism is controlled to rotate to the corresponding position and then stop. After obtaining the one-dimensional code content, the PLC sends the one-dimensional code content to the factory informatization. The factory informatization grabs the casting data of the current wheel hub stored in the server according to the current casting equipment production schedule, generates a pneumatic code and sends it to the PLC. The PLC sends the pneumatic code content to the pneumatic coding machine 4 and triggers the coding work. The pneumatic coding machine 4 engraves the received pneumatic code content in the form of a two-dimensional code at a specific position of the wheel hub. After the coding is completed, the servo lifting device 1 descends to the grabbing position, and the ball center mechanism 3 releases the wheel hub. The current wheel hub is transported out of the pneumatic coding equipment by the pneumatic coding conveying roller 6, and the pneumatic coding machine 4 waits for the next wheel hub to enter and starts a new working cycle.

[0023] Laser coding: After the wheel hub with pneumatic coding is heat treated, it passes through the laser coding conveyor roller 13 and the laser coding equipment. The wheel hub ball center and one-dimensional code scanning process are consistent with the pneumatic coding process. The laser coding ball center clamping mechanism 12 centers the wheel hub and clamps the wheel hub. After the wheel hub is clamped, the laser coding servo lifting device 7 lifts the wheel hub to a certain height. After the lifting, the laser coding servo rotating mechanism 8 drives the wheel hub to rotate to a certain angle. This angle ensures that the one-dimensional code scanning device can completely scan the one-dimensional code on the wheel hub. When the rotating mechanism starts to rotate, the PLC sends a signal to the laser coding one-dimensional code scanning device 9 to start scanning. When the rotating mechanism rotates to the set angle, the laser coding one-dimensional code scanning device 9 scans the pre-cast one-dimensional code on the wheel hub and sends it to the PLC. After the one-dimensional code scanning is completed , PLC matches the scanned one-dimensional code content with the formula stored in the PLC to rotate the wheel hub to a specific angle. At this time, the two-dimensional code scanning device 10 performs pneumatic code scanning, and the PLC sends the scanned pneumatic code content to the factory informatization. The factory informatization generates the two-dimensional code data of the wheel hub according to the one-dimensional code content matching the data stored in the system and sends it to the PLC. The PLC controls the servo module of the rotating mechanism 8 and the laser coding machine 11 to move the wheel hub and the laser coding machine to the marking position of the wheel hub of this type. After the wheel hub and the laser coding machine 11 arrive at the position, they start to engrave the laser two-dimensional code. After the coding is completed, all mechanisms return to their original positions, and the wheel hub is transported out of the laser coding device by the laser coding conveying roller 13. The laser coding device waits for the next wheel hub to enter and starts a new working cycle.

[0024] In this embodiment, the control information of the PLC is sent, and the way of generating the pneumatic code and the QR code by factory informationization adopts the existing technology, which is not within the scope of the innovation protection of this application. Through the above method, the information code of the hot part of the wheel hub is perfect and easy to trace.

[0025] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
