Description

Technical Field

[0001] The embodiments of the present invention relate to the field of intelligent identification and control, and in particular to a production system and an intelligent handling error correction method, device and electronic equipment thereof. Background Art

[0002] Under Body Coating (UBC) is a process for spraying sealant on the bottom of the vehicle body and is an important part of vehicle assembly.

[0003] In the existing vehicle gluing operation, a trolley is usually used to transport the vehicle model workpiece, and a hoist is used to lift the vehicle model workpiece to perform the gluing operation. When the trolley arrives at the entrance of the gluing operation, the trolley code is identified by the photoelectric detection scanner to obtain the specific information of the vehicle model workpiece carried. Subsequently, the hoist lifts the vehicle model workpiece, performs the predetermined gluing operation, and the trolley continues to move forward along the production line. After the gluing is completed, the vehicle model workpiece is returned to the original trolley, and the original trolley transports the vehicle model workpiece to the next processing step according to the predetermined processing process. The prior art has the following problems: In the prior art, the trolley and the vehicle model workpiece are not verified. If the correspondence between the trolley and the vehicle model workpiece is wrong during the processing and transportation process, it is easy to cause the color of the vehicle body spray paint to be wrong in the next processing step, or the vehicle body may be scrapped due to the collision of the manipulator, and the problems of bumps and falls may occur during the fault investigation. In addition, the correspondence between the trolley and the vehicle model workpiece is checked manually, which is prone to missed inspections, and the inspection efficiency is low, which affects production efficiency.

[0046] Embodiment 1

[0047] Figure 1 A flowchart of a production system intelligent handling and error correction method provided in the first embodiment of the present invention. The embodiment of the present invention is applicable to the situation where the workpiece is transferred between different carriers in the production system intelligent handling and error correction system. The method can be executed by the production system intelligent handling and error correction control device provided by the embodiment of the present invention. The production system intelligent handling and error correction control device can be implemented in the form of hardware and / or software. The production system intelligent handling and error correction control device can be configured in the production system or set in an independent electronic device. In the embodiment of the present invention, the production system includes but is not limited to the UBC spray production system. The production system includes a transport trolley and a hoist. The transport trolley can be understood as a carrier for transporting specific workpieces (such as vehicle model workpieces), which can be automatically or manually moved to different processing positions; the hoist can be understood as a temporary carrier for lifting the workpiece to perform the processing procedure.

[0048] like Figure 1 As shown, the method includes:

[0049] S110 . At a first processing position A1 of the production system, first trolley data of a transport trolley, workpiece data of a workpiece to be processed carried by the transport trolley, and first hoisting device data corresponding to the workpiece data are acquired.

[0050] Among them, the first processing position A1 can be understood as the starting position of the workpiece entering a specific processing process (such as a spraying process) in the production system; the first trolley data can be understood as the identity authentication information corresponding to the transport trolley carrying the workpiece to be processed at the first processing position A1, which may include the trolley code, trolley model, etc.; the workpiece data of the workpiece to be processed can be understood as the information required for the workpiece to be processed in the current process flow, which may include the workpiece model, workpiece code, etc. Taking the UBC spraying production system as an example, the workpiece to be processed is a body structural part, and the workpiece data of the workpiece to be processed includes the vehicle model (such as microcar (A00 class), small car (A0 class), compact car (A class), medium-sized car (B class), medium and large car (C class), large car (D class), etc.) and workpiece code; the first hoist data can be understood as the identity authentication information corresponding to the hoist, which may include the hoist code, hoist model, etc.

[0051] Specifically, when the trolley carries the workpiece to the first processing position A1, the first trolley data (such as trolley code, trolley model) of the transport trolley is obtained through a scanning device (such as a barcode scanner) and / or an image detection device (such as a camera); based on the pre-stored correspondence between the transport trolley and the workpiece, the workpiece data (such as the workpiece model, size, etc.) of the workpiece to be processed on the transport trolley is obtained; the first sling data (such as the sling code) of the sling assigned to the first processing position A1 is obtained through a scanning device (such as a barcode scanner) and / or an image detection device (such as a camera). At this time, the workpiece is located on the transport trolley, and the trolley data and the workpiece data are bound to each other.

[0052] S120, unbinding the workpiece data from the first vehicle data according to the transport status between the workpiece to be processed and the transport vehicle.

[0053] In the embodiment of the present invention, the movement of the workpiece to be processed between the transport trolley and the hanger is performed by a transport device (such as a lift).

[0054] Among them, the transport status is used to indicate whether the workpiece to be processed has left the transport trolley; data unbinding can be understood as that the two sets of data are no longer associated.

[0055] Specifically, when the workpiece leaves the transport trolley (such as receiving a signal from the transport device indicating that the workpiece has left the trolley), the workpiece data and the first trolley data are unbound.

[0056] S130 , performing data binding on the workpiece data and the first hoist data according to the hoisting state of the workpiece to be processed by the hoist.

[0057] The hoisting status is used to indicate whether the workpiece to be processed has been hoisted; data binding can be understood as associating two sets of data in the database.

[0058] Specifically, when the lifting of the workpiece is completed (such as receiving a loading signal from the lifting device), the workpiece is deemed to be transferred from the trolley to the lifting device, and the workpiece data is bound to the lifting device data accordingly.

[0059] S140, obtaining the workpiece displacement data corresponding to the binding data, and the trolley displacement data of the empty trolley after unbinding.

[0060] Among them, the workpiece displacement data can be understood as the displacement data of the workpiece in the current process flow and its execution time, wherein the displacement data includes but is not limited to translation, flipping, rotation, etc.; the empty car displacement data mainly includes the moving path and execution time.

[0061] Specifically, the workpiece displacement data in the current processing step is obtained through the pre-stored process flow of the workpiece to be processed in the processing step (such as the workpiece enters station A to be processed for t1 time, and then enters station B to be processed for t2 time).

[0062] S150. At the second processing position A2 of the production system, obtain the second trolley data of the transport trolley to be verified and the second spreader data of the spreader to be verified.

[0063] Among them, the second processing position A2 can be understood as the end position of the current specific processing process before the workpiece enters the next specific processing process in the production system (such as sheet metal spraying process) after the current specific processing process is completed; the second trolley data and the second hoist data can be understood as the data of the trolley and hoist located at the second processing position A2.

[0064] Specifically, after the current process is completed and before entering the next process, the workpiece is on the spreader and is about to be transferred from the spreader to the trolley. The second spreader data of the spreader and the second trolley data of the trolley are obtained by scanning and / or image recognition.

[0065] S160, performing error correction verification on the handling process according to the matching result between the second trolley data and the trolley displacement data, and the matching result between the second hanger data and the workpiece displacement data.

[0066] The matching result may be data consistency or data inconsistency.

[0067] Specifically, when the second trolley data is inconsistent with the trolley displacement data, it means that an error has occurred in the trolley in the current process flow; when the second hoist data is inconsistent with the hoist displacement data, it means that an error has occurred in the trolley in the current process flow; when any of the above situations occurs, it is deemed that the error correction verification has failed.

[0068] The technical solution of the embodiment of the present invention is as follows: first, at the first processing position A1 of production, the first trolley data of the transport trolley, the workpiece data of the workpiece to be processed carried on the transport trolley, and the first hoist data corresponding to the workpiece data are obtained through scanning and image recognition technology. Then, based on the moving progress of the workpiece to be processed between the transport trolley and the hoist, the hanging carrier of the workpiece is intelligently switched. When the workpiece leaves the transport trolley, the data unbinding operation is performed to unlink the workpiece data from the first trolley data; when the workpiece is lifted by the hoist, the data binding operation is performed to associate and bind the workpiece data with the first hoist data. When the hoist drives the workpiece to be processed to perform the processing operation, the workpiece data always maintains a binding state with the corresponding hoist. Furthermore, based on the flow data of the transport trolley and the workpiece to be processed in the processing process, the workpiece displacement data and the trolley displacement data are obtained. Finally, at the second processing position A2 of production, it is verified whether the trolley, the hoist and the corresponding displacement data are consistent. It is realized that the real-time position of the workpiece is determined based on the carrier information without directly monitoring the workpiece, and it is judged whether the current process flow has errors in execution or information transmission.

[0069] Optionally, the intelligent handling error correction method of the production system also includes: sending at least one of the first trolley data, workpiece data, first hoist data, second trolley data, second hoist data, trolley displacement data, workpiece displacement data or error correction verification results to the human-computer interaction device for real-time display.

[0070] Among them, the human-computer interaction device can be understood as an electronic device with input, output and display functions (such as a touch screen), which allows users to interact with it in real time and intuitively, including but not limited to displaying the execution status of the process flow or error correction verification results.

[0071] Specifically, the processing progress, current position and error information of any workpiece in the process flow are reflected in the form of text, image, sound, etc. at the display output end of the human-computer interaction device.

[0072] Furthermore, the intelligent handling error correction method of the production system also includes: canceling the error correction alarm on the human-computer interaction device, and correcting the erroneous data of the handling trolley, the workpiece to be processed and the hanger, and resetting the production system.

[0073] Specifically, the human-computer interaction device has an input end, which can modify in real time at least one of the first trolley data, workpiece data, first hoist data, second trolley data, second hoist data, trolley displacement data, workpiece displacement data or error correction verification results to help the process flow return to normal production after eliminating errors.

[0074] Embodiment 2

[0075] Figure 2 A flow chart of another intelligent handling error correction method for a production system provided in Example 2 of the present invention. Based on the above embodiments, the embodiment of the present invention optimizes the "error correction verification of the handling process based on the matching results of the second trolley data and the trolley displacement data, and the matching results of the second hoist data and the workpiece displacement data" in the above embodiments, which may specifically include: when the second trolley data and the trolley displacement data do not match each other, or the second hoist data and the workpiece displacement data do not match each other, an error correction alarm is issued; when the second trolley data and the trolley displacement data match each other, and the second hoist data and the workpiece displacement data match each other, a secondary verification is performed on the second trolley data and the workpiece data; after the secondary verification is passed, the second trolley data and the workpiece data are bound.

[0076] like Figure 2 As shown, the method includes:

[0077] S210. At a first processing position in the production system, first trolley data of a transport trolley, workpiece data of a workpiece to be processed carried by the transport trolley, and first hoist data corresponding to the workpiece data are acquired.

[0078] S220: Unbind the workpiece data from the first vehicle data according to the transport status between the workpiece to be processed and the transport vehicle.

[0079] S230 , performing data binding on the workpiece data and the first hoisting tool data according to the hoisting state of the workpiece to be processed by the hoisting tool.

[0080] S240, obtaining the workpiece displacement data corresponding to the binding data, and the trolley displacement data of the empty trolley after unbinding.

[0081] S250. At the second processing position of the production system, obtain the second trolley data of the transport trolley to be verified and the second spreader data of the spreader to be verified.

[0082] S260: When the second trolley data does not match the trolley displacement data, or when the second hoist data does not match the workpiece displacement data, an error correction alarm is issued.

[0083] Among them, the error correction alarm can be understood as a warning signal issued by the system when an error is detected during the transportation process, which is used to prompt the operator or system to conduct further inspection and processing.

[0084] Specifically, when inconsistencies are found by comparing the second trolley data with the trolley displacement data, as well as the second hoist data with the workpiece displacement data, an alarm mechanism will be automatically triggered to issue a visual, auditory or tactile alarm to attract attention and take corresponding error correction measures.

[0085] S270: When the second trolley data and the trolley displacement data match each other, and the second hoist data and the workpiece displacement data match each other, perform secondary verification on the second trolley data and the workpiece data.

[0086] The secondary verification of the second trolley data and the workpiece data refers to determining whether the correspondence between the second trolley data and the workpiece data is consistent with the correspondence between the transport trolley and the workpiece pre-stored in the system.

[0087] Specifically, after comparing the second trolley data with the trolley displacement data, and the second hoist data with the workpiece displacement data, if all the data match, a secondary verification will be performed to compare the second hoist data with the workpiece data to see if they correspond to each other. When the second trolley data and the trolley displacement data match, and the second hoist data and the workpiece displacement data match, and the correspondence between the second trolley data and the workpiece data is consistent with the correspondence between the transport trolley and the workpiece pre-stored in the system, it is determined that there is no error in the transport process, the error correction verification is passed, and the subsequent process flow can continue.

[0088] S280. After the second verification is passed, the second vehicle data and the workpiece data are bound.

[0089] Specifically, after completing the secondary verification and confirming that there are no errors in the trolley, the hoist and the workpiece, the second trolley data and the workpiece data are associated in the database to complete the data binding.

[0090] The technical solution of the embodiment of the present invention, based on the above-mentioned embodiment, refines the error correction verification process and optimizes the data binding operation after the error correction verification. Specifically, when there is a mismatch between the second trolley data and the trolley displacement data, when the second spreader data is inconsistent with the workpiece displacement data, or when the secondary verification fails, an error correction alarm will be issued in time to help the staff identify and correct errors in production, effectively reducing the negative impact of errors on the overall production progress.

[0091] Optionally, after the secondary verification is passed, the second trolley data and the workpiece data are bound, including: when the hoist transfers the workpiece to be processed to the handling equipment, the workpiece data is unbound from the first hoist data; when the workpiece to be processed is transferred from the handling equipment to the handling trolley, the second trolley data and the workpiece data are bound.

[0092] Among them, it should be noted that the handling equipment can be a hoist, or a handling elevator or a trolley. When the handling equipment is a trolley, data unbinding and data binding are executed at the same time. When the handling equipment is other intermediate carriers, data unbinding is executed first, and then data binding is executed after the workpiece is transferred from the intermediate carrier to the trolley.

[0093] Specifically, when the spreader completes the task of transferring the workpiece to be processed to the handling equipment, the data unbinding operation is automatically performed to separate the workpiece data from the first spreader data. When the workpiece to be processed is transferred from the handling equipment to the handling trolley, the data binding operation is automatically performed to associate the trolley data with the workpiece data, ensuring that the relevant information of the workpiece and its carrier are synchronized and consistent throughout the entire handling and processing process.

[0094] After completing the error correction verification, the embodiment of the present invention further clarifies the timing of data unbinding and binding: when the hoist transfers the workpiece to be processed to the handling equipment, the workpiece data and the first hoist data are automatically unbound; then, when the workpiece is transferred from the handling equipment to the handling trolley, the trolley data is bound to the workpiece data, so that the synchronization of the workpiece data and the new carrier data is more accurate, providing more reliable data support for real-time monitoring and error handling in the production process.

[0095] Embodiment 3

[0096] Figure 3 A flowchart of another intelligent handling error correction method for a production system provided in Embodiment 3 of the present invention. Based on the above embodiments, the embodiment of the present invention optimizes the "obtaining workpiece displacement data corresponding to the binding data, and the trolley displacement data of the empty trolley after unbinding" in the above embodiments, which may specifically include:

[0097] Determine workpiece shift data based on a preset processing procedure of the workpiece to be processed between the first processing position A1 and the second processing position A2;

[0098] The carriage shift data is determined based on a preset movement path of the empty carriage between the first processing position A1 and the second processing position A2.

[0099] like Figure 3 As shown, the method includes:

[0100] S310. At a first processing position A1 of the production system, first trolley data of a transport trolley, workpiece data of a workpiece to be processed carried by the transport trolley, and first hoist data corresponding to the workpiece data are acquired.

[0101] S320, unbinding the workpiece data from the first vehicle data according to the transport status between the workpiece to be processed and the transport vehicle.

[0102] S330 , performing data binding on the workpiece data and the first hoist data according to the hoisting state of the workpiece to be processed by the hoist.

[0103] S340 , determining workpiece shift data based on a preset processing procedure of the workpiece to be processed between the first processing position A1 and the second processing position A2 .

[0104] The preset processing procedure can be understood as the processing steps and sequence duration of the workpiece predefined in the production plan.

[0105] Specifically, the displacement data of the workpiece is determined by confirming the processes that the target workpiece needs to go through from the first processing position A1 to the second processing position A2 in the production plan, and the specific requirements of these processes on the displacement and time of the workpiece.

[0106] S350 , determining the trolley displacement data based on the preset moving path of the empty trolley between the first processing position A1 and the second processing position A2 .

[0107] The preset moving path may be understood as the optimal or designated path from the first processing position A1 to the second processing position A2 planned for the trolley in the production plan and the time required for its movement.

[0108] Specifically, the optimal or specified path that the target trolley needs to pass through from the first processing position A1 to the second processing position A2 in the production plan and the time required for the movement are obtained.

[0109] S360. At the second processing position A2 of the production system, obtain the second trolley data of the transport trolley to be verified and the second spreader data of the spreader to be verified.

[0110] S370. According to the matching result between the second trolley data and the trolley displacement data, and the matching result between the second hoist data and the workpiece displacement data, error correction verification is performed on the handling process.

[0111] Optionally, at the first processing position A1 of the production system, after obtaining the first trolley data of the transport trolley, the workpiece data of the workpiece to be processed carried by the transport trolley, and the first hoist data corresponding to the workpiece data, the method further includes:

[0112] S311, sending the workpiece data to the lifting tool, so that the lifting tool converts the lifting tool according to the workpiece data.

[0113] Among them, the conversion of lifting tools can be understood as the clamping mode preset by the lifting tool in order to adapt to different workpieces.

[0114] Specifically, before the lifting device reaches the first processing position A1, the type of the workpiece to be grasped is obtained, a gripping mode matching the target workpiece is selected, and then the shape of the lifting device is changed.

[0115] For example, when the sling is in the default mode, it can adapt to the standard workpieces of models A, B and C by adjusting the telescopic angle of the clamp to adapt to the handling of these workpieces. However, for special-shaped workpieces such as model D, adjusting the angle alone is not enough. Model D workpieces require adjustment of the spacing between the clamps or additional clamps to ensure that they are firmly clamped. At this time, the sling can automatically complete the morphological transformation according to the preset mode to adapt to the special needs of special-shaped workpiece D.

[0116] The technical solution of the embodiment of the present invention, on the basis of the above-mentioned embodiments, sends the workpiece data to the sling, so that the sling can convert the lifting tool according to the workpiece data, thereby adapting to workpieces of different shapes and sizes, improving the flexibility and adaptability of the sling, ensuring the safe and accurate handling of various types of workpieces, and reducing handling errors caused by irregular shapes or special sizes of workpieces. In addition, the embodiment of the present invention also clarifies the method for obtaining the displacement data, using the preset processing procedure of the workpiece to be processed between the first processing position A1 and the second processing position A2 to determine the workpiece displacement data, and the preset moving path of the empty trolley between the first processing position A1 and the second processing position A2 to determine the trolley displacement data. If an error occurs in the subsequent production process, the error in the production process can be quickly determined based on the displacement data.
