Description

Technical Field

[0001] The present application relates to the technical field of engine detection, and in particular to a detection device for an engine cylinder. Background Art

[0002] As the requirements of automobile customers for engine performance continue to increase, people's requirements for engine cylinder block / cylinder head performance are also increasing. As the power core of a car, the working performance and stability of the engine determine the quality of a car; the high-speed rotation of the engine during operation will generate high temperature, and a cooling medium is needed to circulate and cool it. The smoothness of the cooling channel plays a decisive role in the cooling effect of the engine.

[0003] After the engine is cast, it is mainly cut by rotary tools. The different types and parameters of rotary tools in each process will produce chips of different lengths and shapes. Some spring-shaped aluminum chips may get stuck in the cooling water channels of the engine block. Even during the high-pressure and high-frequency cleaning process, they cannot be completely cleaned, resulting in engine blocks with quality problems being sent to the assembly process, which ultimately affects the cooling performance and operating reliability of the vehicle during use, and even threatens the safety of the vehicle.

[0004] At present, quality control in the production and processing links is basically based on manual visual inspection after high-pressure and high-frequency cleaning. The quality of quality control depends entirely on the concentration and professionalism of the human workers. At the same time, humans are easily affected by factors such as the environment and personal emotions, resulting in unstable product quality. Since it is a visual inspection, the inspection process cannot be archived to achieve process traceability management of parts quality control. Utility Model Content

[0044] In an optional exemplary embodiment, the imaging mechanism 14 includes a driving mechanism, a light source 141 and a camera 142; the driving mechanism includes a lifting driving shaft 143 (Z-axis driving shaft) and a horizontal driving shaft 144 (X-axis driving shaft), the lifting driving shaft 143 is used to drive the camera 142 to rise or fall, and the horizontal driving shaft 144 is used to drive the camera 142 to move horizontally along the direction of operation of the engine cylinder 20 to be inspected; the light source 141 is used to illuminate a preset position of the engine cylinder 20 to be inspected; the driving mechanism, the light source 141 and the camera 142 are all connected to the control mechanism.

The control mechanism controls the switch of the light source 141, so that when it is necessary to take a photo, the light source 141 is turned on to make the taken photo clearer.

[0046] It should be noted that the camera 142 is an industrial camera 142 , and the camera 142 has a lens 145 .

The workbench conveying motor 152 and the driving motor of the workbench blocking mechanism 153 are both connected to the control mechanism. With such a configuration, during operation, when the engine block 20 after the inspection is run onto the workbench conveying structure 151, the workbench conveying motor 152 drives the workbench conveying structure 151 to run the engine block 20 to a preset position, that is, near the position of the workbench blocking mechanism 153, and the driving motor of the workbench blocking mechanism 153 drives the workbench blocking mechanism 153 to block the engine block 20.

[0050] It should be noted that, specifically, in this embodiment, the engine cylinder body detection device 10 further includes a rotating mechanism 16, which is used to drive the rejection workbench 15 to rotate; the rotating mechanism 16 is connected to the control mechanism. In this way, the rotating mechanism 16 drives the rejection workbench 15 to rotate, so that the rotating workbench will turn to different directions, thereby conveying normal products and abnormal products to different directions, thereby effectively distinguishing abnormal products from normal products. The rotating mechanism 16 is connected to the control mechanism, so that the control mechanism controls the start of the rotating mechanism 16 to rotate it in a preset direction.

[0051] Exemplarily, the rotating mechanism 16 is driven to rotate by the rotation driving motor 161 .

[0053] It should be noted that, specifically, in this embodiment, an abnormal product storage table 17 and a normal product storage table 18 are provided; the rotating mechanism 16 drives the rejection table 15 to rotate so that the rejection table 15 is docked with the abnormal product storage table 17 or the normal product storage table 18. In this way, during operation, when the control mechanism receives that the engine cylinder 20 fails to read the information code or the photo analysis result is abnormal, the rotating mechanism 16 will be controlled to drive the rejection table 15 to rotate toward the abnormal product storage table 17, so that the rejection table 15 is docked with the abnormal product storage table 17, and the engine cylinder 20 that fails to read the information code or the photo analysis result is abnormal is transported to the abnormal product storage table 17 by the table conveying structure 151 of the rejection table 15. When the control mechanism receives that the photo analysis result of the engine cylinder body 20 is normal, it will control the rotating mechanism 16 to drive the rejection table 15 to rotate toward the normal product storage table 18, so that the rejection table 15 is docked with the normal product storage table 18, and the engine cylinder body 20 with the photo analysis result being normal is transported to the normal product storage table 18 under the transportation of the table conveying structure 151 of the rejection table 15. It can be understood that the normal product storage table 18 can also be the back-end process of the engine cylinder body 20 inspection.

[0054] In an optional exemplary embodiment, the angle between the abnormal product storage station 17 and the normal product storage station 18 is 90°; the rotating mechanism 16 can rotate in a range of 0° to 90°.

[0055] It should be noted that, specifically, in this embodiment, the angle between the abnormal product storage table 17 and the normal product storage table 18 is 90°; the rotation range of the rotating mechanism 16 is 0° to 90°. In this way, the rotating mechanism 16 can be rotated by 0° or 90° to achieve the docking of the rejection workbench 15 with the normal product storage table 18 or the abnormal product storage table 17.

[0056] In an optional exemplary embodiment, the engine block detection device 10 further includes an alarm mechanism, which is disposed near the abnormal product storage station 17 and is connected to the control mechanism.

[0057] It should be noted that, specifically, in this embodiment, the engine cylinder body detection device 10 also includes an alarm mechanism, which is arranged near the abnormal product storage table 17 and connected to the control mechanism. In this arrangement, when an abnormal product is stored on the abnormal product storage table 17, the control mechanism controls the alarm mechanism to sound an alarm, so that nearby staff can manually review and inspect the abnormal products on the abnormal product storage table 17. When the review result is a normal product, it can be placed in the normal product storage table 18, thereby avoiding the misjudgment of normal products due to the misjudgment of the detection device.

[0058] The engine cylinder body detection device 10 provided in the present application replaces the fully automatic device for manual visual detection. The overall detection process is briefly described as follows:

[0059] The engine cylinder 20 to be inspected is fed from the front end of the assembly line. When it is transported to the photoelectric sensor at the entrance of the inspection station, the blocking motor is started, driving the blocking limit column 121 to rise, intercepting the engine cylinder 20 to be inspected, and the control mechanism controls the driving motor 111 of the conveying mechanism to stop running.

[0060] The information reading mechanism 13 takes a photo of the two-dimensional code on the engine cylinder block 20 to be inspected;

[0061] If the two-dimensional code reading fails, the blocking limit column 121 rises and falls, and the driving motor 111 of the conveying mechanism is started to convey the engine cylinder 20 to the rejection workbench 15 for rejection and sorting to the abnormal product storage table 17;

[0062] When the QR code is read successfully, the control mechanism controls the light source 141 to light up, the lifting drive shaft 143 and the horizontal drive shaft 144 servo motion platform are started, and the camera 142, the lens 145 and the light source 141 move multiple times according to the moving step set by the field of view size to take pictures; after taking pictures, the background synchronously processes the pictures and analyzes the pictures. After taking pictures, the lifting drive shaft 143 and the horizontal drive shaft 144 servo motion platform return to the standby position;

[0063] After the whole engine cylinder body 20 is photographed, the blocking limit column 121 is lowered, the driving motor 111 of the conveying mechanism is started, the workbench conveying motor 152 of the rejecting workbench 15 is started, and the workbench blocking mechanism 153 of the rejecting workbench 15 is raised, and the engine cylinder body 20 is conveyed to the workbench conveying structure 151 to wait for the inspection result, and the workbench conveying motor 152 stops running at this time;

[0064] When the analysis and detection result of the product image is OK, the workbench blocking mechanism 153 is lowered, the workbench conveying motor 152 is started, and the normal engine cylinder 20 is conveyed to the normal product storage table 18, that is, the back-end process;

[0065] When the analysis and detection result of the product image is NG, the motor of the rotating mechanism 16 starts, driving the rejection workbench 15 to rotate 90° as a whole, the workbench blocking mechanism 153 descends, and the workbench conveying motor 152 starts, and the abnormal engine cylinder 20 is conveyed to the abnormal product storage table 17; when the engine cylinder 20 is transported to the end of the abnormal product storage table 17, the rotating mechanism 16 drives the rejection workbench 15 to rotate back 90° to reset, and at the same time the workbench blocking mechanism 153 rises, waiting for the next material to enter;

[0066] When abnormal products are stored in the abnormal product storage station 17, the alarm mechanism sends out an audible and visual alarm prompt, so that operators at nearby workstations can manually review the abnormal products and make corresponding operational arrangements.

[0067] The engine cylinder block inspection device 10 provided in the present application replaces the fully automatic device for manual visual inspection and is fully applicable to assembly line production; at the same time, the inspection process image information and inspection results can all be archived and uploaded to the user's MES system for product quality traceability.

[0068] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present application.

[0069] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not further describe various possible combinations.
