Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection technology, and in particular to a heat shield integrated visual inspection device. Background Technology

[0002] The turbocharger heat shield is a critical protective component for automotive turbochargers. Its structural stability and assembly accuracy directly affect the turbocharger's performance. Turbocharger heat shield products require the attachment of various accessories such as clips, nuts, rivets, and brackets. Figure 7 , 8 As shown, the installation position, orientation and integrity of accessories are subject to extremely high requirements. Loss, reverse installation or incorrect installation of accessories will lead to assembly failure and even safety hazards. Therefore, it is currently necessary to use technical means to effectively detect the installation of many parts.

[0003] Currently, the control method for conventional turbocharger heat shields in China is to visually inspect the assembly status of sub-components. Manual final inspection relies on visual judgment, which is prone to problems such as reversed or missing accessories due to fatigue and negligence. Furthermore, it cannot achieve 100% full inspection, posing a quality risk. Therefore, photographic equipment is needed for error prevention inspection. Obviously, manual final inspection relies on visual judgment, which has insufficient error prevention capabilities and is prone to problems such as reversed or missing accessories due to fatigue and negligence, posing a quality risk.

[0004] The conventional production process for turbocharger heat shields is as follows: heat shield stamping → accessory riveting → photographing and inspecting sub-parts → laser marking QR codes → QR code scanning → pressing status code marking → shipment. This process has the following defects:

[0005] Low production efficiency: Traditional processes require multiple workstations such as visual inspection, laser marking, barcode scanning, and status code stamping. Products need to be manually transferred between workstations, which not only occupies a lot of space and increases the number of operators, but also extends the production cycle due to handling and waiting during the transfer process.

[0006] There are many potential quality risks: During the multi-station turnover process, products are prone to secondary damage such as deformation and scratches due to collisions and friction. In addition, the equipment at each station operates independently, and information from inspection, coding, and labeling cannot be linked, making it difficult to achieve full-process quality monitoring.

[0007] To address the aforementioned issues, there is an urgent need to design an integrated device that combines detection, coding, labeling, and traceability functions to improve production efficiency, reduce quality risks, and save costs. Utility Model Content

[0008] This invention aims to address the technical problem of the lack of integrated inspection equipment for turbocharger heat shields in existing technologies. It addresses issues such as insufficient error prevention capabilities, poor traceability, low production efficiency, and numerous quality risks in the production of turbocharger heat shields by providing an automated device that integrates visual inspection, laser marking, status code stamping, and barcode scanning traceability. This device achieves integrated processing throughout the entire process, improving product quality and production efficiency.

Vision inspection is used to acquire images of attachments (clamps, nuts, rivets, brackets, etc.) on the surface of a workpiece when it is transported to the processing area. Image recognition technology is used to detect the installation position, orientation, and integrity of these attachments (e.g., whether they are missing or installed backwards), and the inspection results are sent to the control system (terminal equipment). (See attached image.) Figure 9 The exhibition is shown in China.

[0083] In one specific embodiment, the side beam crossbar 201 is connected to the frame longitudinal beam 10a and is located on the lower side of the frame, adjacent to the workpiece fixture 100.

[0084] The side beam crossbar 201 includes two sets;

[0085] One set of side beam crossbars 201 is used to connect the laser marking head 200, and the other set of side beam crossbars 201 is used to connect the high-intensity light source.

[0086] Visual inspection is also used to capture images of the QR code on the workpiece surface after the laser marking head 200 has completed laser marking, identify the clarity, integrity and information of the QR code, and send the identification results to the control system (terminal equipment).

[0087] The laser marking head 200 is electrically connected to the control system, including a laser generator and a marking head; the laser marking unit is used to laser mark a unique QR code (containing information such as product batch, production time, and processing station) at a preset position on the workpiece surface after the vision inspection unit confirms that the workpiece accessories are installed correctly, according to the instructions sent by the control system.

[0088] In one specific embodiment, the top balance beam 1010

[0089] The device is equipped with an alarm light 800, whose alarm function module is electrically connected to the control system, including an audible and visual alarm.

[0090] When the vision inspection unit detects that the workpiece accessories are not installed properly (such as missing or reversed), the QR code recognition fails (such as blurry or incomplete), or the status code stamping is abnormal, the control system triggers the alarm module to issue an audible and visual alarm, and at the same time controls the conveyor mechanism to stop conveying until it is manually handled and restarted.

[0095] In one embodiment, as shown in the appendix Figure 1 , 2 As shown in Figure 7, it also includes:

[0096] Status code stamping assembly 500, the status code stamping assembly 500 is arranged on one side of the workpiece fixture 100;

[0097] The status code stamping assembly 500 includes:

[0098] The connecting frame 503 has a mounting connection end 503a, on which a stamping cylinder 502 is mounted. The output end of the stamping cylinder 502 is perpendicular to the horizontal plane and connected to a status code stamping header 501. The status code stamping assembly is electrically connected to the control system and includes a stamping cylinder and a status code stamping header 501. The status code stamping header has character status codes 1-9 corresponding to the product status. The stamping unit is used to stamp status codes at preset positions on the workpiece surface according to the instructions of the control system after laser marking is completed, so as to intuitively identify the product status.

[0099] The control system (terminal equipment) uses a PLC controller or industrial computer and is electrically connected to the conveying mechanism, integrated processing module, and alarm module. The control system is used to receive the detection results of the vision inspection unit and the QR code information of the barcode scanning unit, control the start and stop of the laser marking unit and the stamping unit, and adjust the conveying speed of the conveying mechanism. At the same time, the control system has a built-in storage module to store data such as the detection image of the workpiece, QR code information, status code information, and processing time, which can be displayed in real time through an external display screen.

[0100] Technical requirements for the integrated visual inspection equipment in this heat insulation cover:

[0101] This equipment can detect the presence or absence of relevant detection points on the heat insulation cover (as shown in the attached document). Figure 8 , 9 As shown in the figure), the current detection status is displayed on the display 900. When the detection is qualified, a status code is automatically marked. When the detection is unqualified, an audible and visual alarm is triggered (manual intervention is required to manually press the button to cancel the alarm and check the workpiece).

[0102] The visual inspection equipment integrated into this heat shield can perform the following visual inspection items:

[0103] Please see the appendix Figure 8 , 9 As shown:

[0104] Second detection position 2, to check for the presence or absence of rivets; The seventh inspection point 7 checks for the presence or absence of rivets; The third detection position 3 checks for the presence or absence of clips; The eighth inspection point, 8, checks for the presence of welded nuts (by thread inspection); The fourth inspection point 4 checks for the presence or absence of rivets; The ninth detection position 9 checks for the presence or absence of a support bracket; The fifth detection position 5 is used to check the presence and orientation of the support bracket. The tenth detection position 10 checks for the presence or absence of a support bracket; The eleventh inspection point 11 checks for the presence or absence of a support;

[0105] The following detection points are also included (not fully shown in the image):

[0106] Clamp orientation check, left and right clamps installed in reverse, clamp model incorrectly installed, booster heat shield clamp orientation check, stainless steel spring sheet orientation check, identification of stamping markings, hole inspection for missing stamping.

[0107] The workflow steps of the integrated visual inspection equipment for this heat insulation cover are as follows:

[0108] Step S1: The workpiece to be processed is conveyed to the processing area of ​​the integrated processing module by the conveying mechanism. The conveying mechanism stops and the workpiece is fixed by the workpiece fixture 100.

[0109] Step S2: Visual inspection (photographic visual inspection lens 700) is started to acquire images of the workpiece surface accessories. The image recognition algorithm is used to detect whether the accessories are missing or installed backwards, and the detection results are sent to the control system.

[0110] Step S3: If the inspection is qualified, the control system instructs the laser marking (QR code scanning lens 400) to start, and a unique QR code is engraved at a preset position on the workpiece surface; if the inspection is unqualified, the control system triggers the alarm module, and manual handling is required.

[0111] Step S4: After the laser marking is completed, the vision detection unit collects the QR code image again, the scanning unit recognizes the QR code information (such as batch and time), and sends it to the control system.

[0112] Step S5: If the QR code recognition is successful, the control system instructs the stamping unit to start and stamp a "qualified" status code at a preset position on the workpiece surface; if the QR code recognition fails, the alarm module is activated and manual handling is required.

[0113] Step S6: After the status code stamping is completed, the vision inspection unit acquires the status code image, associates it with the QR code information and the accessory detection image, and stores it in the control system.

[0114] Step S7: Once all processes are completed, the conveying mechanism is activated to transport the workpiece to the next stage, and the equipment enters the next work cycle.

[0115] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
