Abstract
Description
Technical Field
[0001] This application relates to the field of automotive manufacturing technology, and in particular to a fault-prevention primer system. Background Technology
[0002] Automated primer coating equipment is now used in automobile production. Primer coating is a common pretreatment process in the industrial field. Automobile components such as glass, sunroofs, frames, tailgates, and interior trim often require assembly or bonding. To ensure stronger adhesion, primer agents are used to enhance surface activity and improve the adhesion of subsequent adhesives. To complement automated primer coating equipment, large workpieces are often fed and transported automatically, with alignment and adhesive application performed within the primer coating equipment. This is especially true for automotive sunroofs, which are fragile, large, and heavy, making manual transport difficult. Currently, automated mechanical transport and adhesive application are used. The sunroof glass is retrieved from the material warehouse, placed on the conveyor line, and then transported to the alignment device for alignment. After alignment, a signal is sent to the robot to begin primer coating.
[0003] However, as the number of vehicle models on the production line increases, the glass shapes of the sunroofs vary. Different models require different sunroof glass designs. When retrieving materials from the warehouse, it is easy to encounter model errors, or the sunroof glass may be retrieved correctly, but the vehicle model to be installed is inconsistent. Because the vehicle model and the sunroof glass are incompatible, the sunroof glass cannot be correctly matched to the corresponding vehicle model during the alignment process. The glue-applying robot cannot effectively apply the primer, resulting in glue application failure. Both the workpiece and consumables are wasted, causing significant economic losses. Summary of the Invention
[0004] Therefore, the purpose of this invention is to overcome the shortcomings of current primer coating systems that cannot effectively prevent glass picking or vehicle model recognition errors, which prevent robots from effectively performing primer coating, and to provide an error-proof primer coating system. This invention can perform a secondary comparison before primer coating to prevent errors, promptly preventing inconsistent materials from flowing out of the primer coating station and effectively ensuring production quality.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A mistake-proof primer system, comprising:
[0007] Workpiece information acquisition device, used to obtain the material warehouse information to which the workpiece is assigned when it enters the warehouse;
[0008] A workpiece conveying device is used to extract workpieces from the corresponding material warehouse and convey them to the primer coating device;
[0009] Vehicle model acquisition device, used to identify vehicle models produced on the production line;
[0010] Primer applicator, used to perform primer application on workpieces;
[0011] A centering device is located on one side of the primer coating device and is used to perform a centering procedure on the workpiece in the primer coating device.
[0012] A size recognition device is disposed on the centering device and is used to identify the size of the workpiece in the centering device;
[0013] Alarm devices are used for audible and visual warnings;
[0014] The control device is pre-set with material library information data corresponding to different vehicle models and workpiece size data corresponding to different vehicle models; the control device is respectively connected to the workpiece information acquisition device, workpiece conveying device, vehicle model acquisition device, primer coating device, centering device, size recognition device and alarm device.
[0015] This invention uses a workpiece information acquisition device to identify the information of workpieces placed in the material warehouse. The control device, based on the vehicle model acquisition device, can obtain the first vehicle model information of the currently produced model. Since the control device is associated with both the material warehouse and vehicle model information, it can control the workpiece conveying device to extract the workpiece from the corresponding material warehouse. The workpiece is then transported by the workpiece conveying device to the centering device. The size recognition device collects the workpiece's size information. Because the control device is associated with both the workpiece size and vehicle model information, it can extract the corresponding second vehicle model information based on the size information. The control device compares the first and second vehicle model information for consistency. If they match, the control device controls the centering device to center the workpiece. After centering, the primer coating device performs the primer coating operation. If they do not match, the control device controls the alarm device to issue a warning, allowing workers to respond quickly and manually correct the issue before continuing centering. This invention features high integration, automatically identifying vehicle models, automatically picking up and conveying workpieces for centering, and performing a secondary comparison before primer coating to prevent errors and promptly prevent inconsistent materials from flowing out of the primer coating station. Picking up, centering, and primer coating are all automated, effectively ensuring production quality.
[0016] Furthermore, the workpiece information acquisition device is a scanner for recognizing the QR code on the workpiece material frame, and the scanner is communicatively connected to the control device. When a workpiece enters the material storage area, the QR code on the material frame is scanned. The control device compares and processes the read information to distinguish between different workpieces, facilitating the subsequent selection of the corresponding material storage area based on the vehicle model.
[0017] Furthermore, the vehicle model acquisition device is a REID reader / writer for reading the vehicle's VIN code, and the REID reader / writer is communicatively connected to the control device. RFID readers / writers are deployed on the production line to read the vehicle's VIN code using the code on the vehicle body. The control device compares and processes the read information to confirm the vehicle model and obtain the first vehicle model information.
[0018] Furthermore, the size recognition device includes an ultrasonic sensor, which is communicatively connected to the control device. The ultrasonic sensor measures the position, shape, and size of an object by emitting and receiving ultrasonic waves. It can perform measurements without contact with the object being measured, is less affected by environmental factors, and is suitable for automated production line scenarios. The ultrasonic sensor obtains size information, and the control device compares and processes the read information to confirm the vehicle model corresponding to the size of the delivered workpiece, obtaining second vehicle model information. At this point, the control device compares the first and second vehicle model information according to preset logic. If they match, the control device controls the centering device to center the workpiece, and after centering, the primer coating device performs a primer coating operation. If they do not match, the control device controls the alarm device to issue a warning, allowing workers to respond quickly and manually correct the issue before continuing centering.
[0019] Furthermore, the workpiece conveying device includes a picking robot for retrieving parts from the material warehouse and a conveyor line for transporting the workpieces.
[0020] Furthermore, the retrieval robot is communicatively connected to the control device.
[0021] Furthermore, the primer coating device includes a gantry and an adhesive coating robot mounted on the gantry, with the conveyor line passing under the gantry.
[0022] Furthermore, the glue-applying robot is communicatively connected to the control device.
[0023] Furthermore, the centering device includes a centering platform, an X-axis centering device and a Y-axis centering device disposed on the centering platform and arranged perpendicularly to each other, and a positioning detection switch disposed on the centering platform. The centering platform is disposed in the conveyor line below the gantry.
[0024] It should be noted that both the X-axis centering device and the Y-axis centering device include structures such as clamping mechanism, drive mechanism and guide mechanism. This is a conventional technical means in this field, so it will not be elaborated in detail. When the position detection switch detects that the workpiece is in place and the consistency comparison is correct, the control device controls the X-axis centering device and the Y-axis centering device to perform the centering operation.
[0025] Furthermore, this utility model also includes a lifting rotary table, which is located below the centering platform. The lifting rotary table allows the workpiece to be lifted off the conveyor line and removed during centering or primer coating equipment malfunctions, enabling manual primer coating to continue, ensuring production efficiency and effectively reducing downtime losses. When not in use, the lifting rotary table can be lowered below the conveyor line, without interfering with normal operations.
[0026] It should be noted that when a lifting rotary table is installed, a clearance space is provided in the middle of the centering platform for the lifting rotary table to move up and down.
[0027] Furthermore, the alarm device includes a horn and a warning light.
[0028] Furthermore, the control device includes a PLC and a valve island. The PLC is a programmable controller capable of pre-setting control logic, processing received signals according to the program, and issuing signals to execute the corresponding control logic. The valve island consists of multiple solenoid valves, a communication module, a pneumatic module, and interfaces, forming a "control island" to reduce the wiring complexity of distributed components and to better connect and control the workpiece information acquisition device, workpiece conveying device, vehicle model acquisition device, primer coating device, centering device, size recognition device, and alarm device.
[0029] Compared with the prior art, the beneficial effects of this utility model are:
[0030] This utility model is highly integrated, capable of automatically identifying vehicle models, automatically picking up and conveying workpieces and centering them, and performing a secondary comparison before the primer coating process to prevent errors, thus preventing inconsistent materials from flowing out of the primer coating station. The picking, centering and primer coating processes are all automated, effectively ensuring production quality. Attached Figure Description

[0048] like Figure 2 As shown, the working principle of this embodiment is as follows: The workpiece information acquisition device 1 identifies the information of the workpiece placed in the material warehouse.
