After correct identification, it is released for the next process.

[0004] The corresponding model of oil seals are picked up and loaded manually, which may lead to wrong picking and loading due to human factors. Even after the assembly is completed, the PLC control system will determine whether the workpiece after the oil seal assembly is compliant, but the wrongly installed oil seal still needs to be removed and replaced, which lengthens the assembly workflow and reduces assembly efficiency.

[0038] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Embodiment 1:

[0040] Figure 1 It is a flowchart of an oil seal feeding error prevention method provided by an embodiment of the present invention; Figure 2 It is a control structure block diagram of the oil seal feeding error prevention device provided by an embodiment of the present invention; Figure 3 It is a schematic diagram of the three-dimensional structure of one side of a closed silo provided in an embodiment of the present invention; Figure 4 FIG. 2 is a schematic diagram of the three-dimensional structure of the other side of the closed silo provided by an embodiment of the present invention. Figures 1 to 4 As shown, an embodiment of the present invention provides an oil seal feeding error prevention method, and the oil seal feeding error prevention method comprises:

[0041] S1. Pre-install oil seals required for different machine models using multiple closed silos 3 , where the closed silos 3 are configured to be communicatively connected with the MES manufacturing execution system 1 .

[0042] Specifically, in this step, according to the product characteristics, the same type of electric drive products have different rotation directions, clockwise and counterclockwise. The difference in rotation direction will slightly differ the single-axis oil seal used for sealing, which is mainly reflected in the opposite direction of the lip texture of the oil seal. Therefore, in this solution, at least two closed silos 3 are provided, which respectively accommodate the two rotation directions corresponding to clockwise and counterclockwise. The two oil seals have exactly the same external dimensions, materials and colors, and are only marked with opposite rotation directions.

[0043] S2. After the workpiece is in place, the RFID tag information on the workpiece is read by the PLC control system 2, transmitted to the MES manufacturing execution system 1 for workpiece model identification, and displayed to the staff.

[0044] Specifically, before the workpiece is assembled, it is first transported through the production line. When it is transported to the workstation of the oil seal assembly process, the PLC control system 2 reads the RFID tag information on the workpiece and uploads it to the MES manufacturing execution system 1. The MES manufacturing execution system 1 is used to identify the workpiece model and display the model information on the display for the assembly staff to view and select the oil seal corresponding to the workpiece model.

[0045] S3. The staff takes out the oil seal from the closed material bin 3 and assembles it with the workpiece according to the identification information of the MES manufacturing execution system 1. When the staff selects the closed material bin 3 where the oil seal matching the identification information is located, the MES manufacturing execution system 1 sends a control instruction to the PLC control system 2 to drive the closed material bin 3 to eject the oil seal; or

[0046] When the staff selects the closed silo 3 where the oil seal that does not match the identification information is located, the MES manufacturing execution system 1 sends a control instruction to the PLC control system 2 to drive the closed silo 3 not to pop out the oil seal.

[0047] Specifically, in this step, the staff takes out the matching oil seal from the corresponding closed silo 3 based on the identification information displayed by the MES manufacturing execution system 1. In the embodiment of the present invention, the closed silo 3 is configured to communicate with the MES manufacturing execution system 1, and it opens and ejects the internal oil seal for the staff to take, or remains closed and is controlled by the MES manufacturing execution system 1 and the PLC control system 2 for hardware joint control. When the staff does not make a selection, the multiple closed silos 3 are all in a locked state. After confirming the type of oil seal to be taken out, the staff presses the opening button on the closed silo 3 and applies to take out the oil seal. If the staff selects the closed silo 3 where the oil seal matching the identification information is located, the MES manufacturing execution system 1 determines that the staff's selection is correct, and the MES manufacturing execution system 1 sends a control instruction to the PLC control system 2 to drive the closed silo 3 to eject the oil seal. The PLC control system 2 drives the closed silo 3 to unlock and automatically eject the oil seal from the closed silo 3. When the worker selects the closed silo 3 where the oil seal that does not match the identification information is located, the MES manufacturing execution system 1 determines that the worker's selection is wrong, and the MES manufacturing execution system 1 sends a control instruction to the PLC control system 2 to drive the closed silo 3 not to eject the oil seal. At this time, the worker cannot obtain the wrong oil seal. Through the MES manufacturing execution system 1 and the PLC control system 2, in conjunction with the hardware joint control of the closed silo 3, mandatory error prevention is achieved for the use of the oil seal, preventing the worker from taking the wrong oil seal and installing it on the workpiece.

[0048] Furthermore, when the staff selects the closed silo 3 where the oil seal that does not match the identification information is located and starts it, when the MES manufacturing execution system 1 determines that the staff's selection is wrong, it will also send a sound signal to the staff through a horn or loudspeaker, or send a light signal to the staff through a signal light to remind them, so that the staff can respond to the selection error in time, replace the correct closed silo 3 to start it, and obtain the oil seal that matches the workpiece for subsequent installation.

[0049] By adopting the oil seal feeding error prevention method provided by the embodiment of the present invention, when the assembly process of the workpiece and the oil seal is performed, the MES manufacturing execution system 1 and the PLC control system 2 are used in conjunction with the hardware joint control form of the closed material bin 3, and the oil seals of different models are independently closed and loaded using the dedicated closed material bin 3. When the workpiece is delivered in place, the PLC control system 2 and the MES manufacturing execution system 1 are used to read and identify the information and feedback it to the staff. The staff takes out the oil seal and the workpiece from the closed material bin 3 for assembly according to the identification information of the MES manufacturing execution system 1. When the closed material bin 3 is selected, the MES manufacturing execution system 1 will judge and check whether the oil seal model selected by the staff is correct based on the identification information, and send a control signal to the PLC control system 2 based on the correctness to drive the closed material bin 3 to eject the oil seal or not, so as to realize forced error prevention, avoid the staff from taking the wrong oil seal and installing the workpiece, and can realize timely error prevention in the workpiece oil seal assembly process flow on the electric drive assembly production line, and improve the overall assembly efficiency.

[0050] For example, in a further optimized embodiment, the entire electric drive assembly production line can also be set to fully automatic control, that is, while the workpiece is delivered to the location, the PLC control system 2 and the MES manufacturing execution system 1 are used to read and identify information, and while the display device is used to provide information feedback to the staff, the PLC control system 2 is directly used to drive the corresponding closed silo 3 to eject the oil seal that correctly corresponds to the workpiece, eliminating the staff's active selection steps, further avoiding mistakes caused by human factors, and no further reminders are required for the staff to re-select. After confirming the information, the staff can directly obtain the corresponding oil seal for accurate installation, further improving the overall assembly efficiency.

[0051] Embodiment 2:

[0052] refer to Figures 2 to 3, the embodiment of the present invention also provides an oil seal feeding error prevention device, characterized in that it includes: an MES manufacturing execution system 1, a PLC control system 2 and a closed silo 3. Among them, there are multiple closed silos 3, which are respectively used to pre-install oil seals required for different models, and the closed silo 3 is configured to communicate with the MES manufacturing execution system 1. The PLC control system 2 is used to read the RFID tag information on the workpiece after the workpiece is in place and transmit it to the MES manufacturing execution system 1. The MES manufacturing execution system 1 is used to identify the workpiece model based on the RFID tag information, and display it to the staff, and when the staff selects the closed silo 3 where the oil seal matching the identification information is located, the control instruction of driving the closed silo 3 to pop out the oil seal is sent to the PLC control system 2; or, when the staff selects the closed silo 3 where the oil seal does not match the identification information is located, the control instruction of driving the closed silo 3 not to pop out the oil seal is sent to the PLC control system 2.

[0053] Exemplarily, the oil seal feeding error prevention device is used to cooperate with the oil seal feeding error prevention method in Example 1. When the assembly process of the workpiece and the oil seal is performed, the MES manufacturing execution system 1 and the PLC control system 2 are used in conjunction with the hardware joint control form of the closed material bin 3 to independently and closedly hold the oil seals of different types. When the workpiece is delivered in place, the PLC control system 2 and the MES manufacturing execution system 1 are used to read and identify the information and feedback it to the staff. The staff takes out the oil seal and the workpiece from the closed material bin 3 according to the identification information of the MES manufacturing execution system 1 for assembly. When the closed material bin 3 is selected, the MES manufacturing execution system 1 will judge and check whether the oil seal model selected by the staff is correct based on the identification information, and send a control signal to the PLC control system 2 based on the correctness to drive the closed material bin 3 to eject the oil seal or not, so as to realize forced error prevention, avoid the staff from taking the wrong oil seal and installing the workpiece, and can realize timely error prevention in the oil seal assembly process of the workpiece on the electric drive assembly production line, and improve the overall assembly efficiency.

[0054] Optionally, the closed silo 3 includes a base plate 31, a storage barrel 32 and a cylinder 33. The storage barrel 32 is arranged above the base plate 31 and perpendicular to the base plate 31. One end of the storage barrel 32 is connected to the base plate 31. A pop-up groove 321 is radially opened at the bottom of the storage barrel 32. The cylinder 33 is arranged on the base plate 31 and is located beside the storage barrel 32. The telescopic rod of the cylinder 33 is arranged toward one end opening of the pop-up groove 321. Illustratively, in an embodiment of the present invention, after confirming the model of the oil seal that needs to be taken out, the staff presses the open button on the closed silo 3 and applies to take out the oil seal. If the staff selects the closed silo 3 where the oil seal matching the identification information is located, the MES manufacturing execution system 1 determines that the staff's selection is correct, and the MES manufacturing execution system 1 sends a control instruction to the PLC control system 2 to drive the closed silo 3 to pop out the oil seal. The PLC control system 2 drives the cylinder 33 to start and extend the telescopic rod and extend it from the opening of the pop-up slot 321 on one side of the storage barrel 32, and pops the oil seal out of the opening of the pop-up slot 321 on the other side of the storage barrel 32. The staff can then take out the popped-out oil seal from the base plate 31 and proceed to the next step of assembly.

[0055] Optionally, the opening size of the pop-up slot 321 matches a single oil seal. For example, in the embodiment of the present invention, the opening height of the pop-up slot 321 matches the thickness of a single oil seal, and the opening width matches the diameter of a single oil seal. Each push of the telescopic rod of the cylinder 33 will only pop out a single oil seal from the closed silo 3. Each operation of the staff will only take out one oil seal, completely eliminating the possibility of mixing or taking the wrong oil seal, and further improving the assembly accuracy.

[0056] Optionally, the barrel body of the storage barrel 32 is made of a transparent material, and a barrel cover 322 is detachably provided on the top of the storage barrel 32. For example, in the embodiment of the present invention, the staff can observe the number of oil seals stored in the closed silo 3 through the barrel body of the transparent material, and open the barrel cover 322 in time when the number is low, and replenish the oil seals in the closed silo 3 from the top of the storage barrel 32, thereby improving practicality.

[0057] Optionally, the oil seal feeding error prevention device also includes an alarm module 4, which is used to receive the control instruction of the MES manufacturing execution system 1 and send an alarm signal to the staff when the staff selects the closed silo 3 where the oil seal that does not match the identification information is located. Exemplarily, in an embodiment of the present invention, when the staff selects the closed silo 3 where the oil seal that does not match the identification information is located and starts, the MES manufacturing execution system 1 determines that the staff has made an error in selection, and sends a sound signal to the staff through the speaker or speaker of the alarm module 4, or sends a light signal to the staff through a signal light to remind the staff, so that the staff can respond to the selection error in time, and replace the correct closed silo 3 to start, so as to obtain the oil seal that matches the workpiece for subsequent installation. Furthermore, the signal light can also be directly set on the side of the corresponding closed silo 3. After the MES manufacturing execution system 1 completes the identification of the workpiece information, the signal light on the side of the corresponding closed silo 3 is directly used to prompt the staff to pick up the oil seal, indicating that the closed silo 3 where the oil seal that matches the identification information is located is selected.
