Description

Technical Field

[0001] The invention relates to the technical field of oil pan detection, and in particular to an automatic production line for detecting and spraying codes on automobile oil pan products. Background Art

[0002] The oil pan of a car is usually located at the bottom of the engine, and is usually in the shape of a basin or a plate. This shape is designed to collect and store the oil that flows back from various lubrication parts during the operation of the engine. There are screw holes on the oil pan to facilitate the subsequent oil replacement. Therefore, during the production process, it is necessary to test its air tightness to avoid oil leakage during actual use.

[0003] The existing oil pan air tightness detection process is mostly manual operation. During the screwing stage, the problem of missing sealing rings in the screws is prone to occur, resulting in a gap between the screws and the oil pan after they are connected, which can easily affect the accuracy of subsequent air tightness detection. In addition, during the manual operation stage, the placement of the oil pan and the tightness of the screws will also affect the subsequent air tightness detection, making the detection efficiency relatively slow, which directly affects the production efficiency of the oil pan. Summary of the invention

[0004] In order to achieve the purpose of improving the air tightness detection efficiency and air tightness detection accuracy of the oil pan, the present invention adopts the following technical solutions:

[0006] A pad is fixedly installed in the detection frame, and a stabilizing device is fixedly installed on the pad. An upper torsion mechanism is also provided in the detection frame, and the upper torsion mechanism includes a support frame installed on the inner bottom surface of the detection frame, a transverse driving seat is provided on the top surface of the support frame, an adjustment plate is provided at the end of the transverse driving seat, a linkage seat for adjusting the relative positions of the transverse driving seat and the adjustment plate is provided between the transverse driving seat and the adjustment plate, a linkage frame is provided on the adjustment plate, a screw gun for tightening screws is provided at the end of the linkage frame, a pneumatic cylinder is provided at the bottom of the adjustment plate, and a screw clamp for loading screws is provided at the end of the pneumatic cylinder.

[0007] Preferably, a vibration plate is provided in the feed box, and a feed rack for receiving screws output from the vibration plate is provided on the top of the vibrator.

[0008] Preferably, a transverse driving cylinder is provided on the top surface of the pad, an electromagnetic adsorption head is provided at the output end of the transverse driving cylinder, and a CCD visual camera is provided on the top surface of the pad directly below the end of the feeding rack.

[0009] Preferably, a transfer track A located below the support frame is fixedly mounted on the top surface of the detection frame, a moving seat A is slidably connected to the top surface of the transfer track A, and a tooling fixture A for placing the workpiece body is provided on the top surface of the moving seat A.

[0010] Preferably, a transfer track B is provided on the top surface of the detection frame, a moving seat B is slidably connected to the transfer track B, and a tooling fixture B for placing the workpiece body is provided on the top surface of the moving seat B.

[0011] Preferably, the top surface of the detection frame is provided with a detection frame located above the transfer track B, the top surface of the detection frame is provided with a main cylinder, and the bottom end of the main cylinder is provided with a leak detection end that cooperates with the tooling fixture B to provide air tightness detection for the workpiece body;

[0012] A leak detector for controlling the leak detection end is arranged at the top front side of the detection frame, and a data computer is arranged at the top right side of the detection frame.

[0013] Preferably, the top surface of the detection frame is provided with a discharge track whose end is connected to the detection frame, and the rear part of the top surface of the inner cavity of the detection frame is provided with a truss track for moving the workpiece body, and the truss track and the detection frame are connected and fixed by a hanger.

[0014] Preferably, a connecting seat is slidably connected to the bottom end of the truss track, and a robot assembly is provided at the bottom end of the connecting seat and the bottom end of the discharge track.

[0015] Preferably, the robot assembly includes a top frame which is fixedly connected to the connecting seat and slidably connected to the discharge track respectively, a driver is provided at the top of the top frame, and a connecting frame which is movably sleeved with the top frame is provided at the bottom end of the driver output shaft.

[0016] Preferably, a de-energized electromagnet for positioning the workpiece body is provided at the bottom end of the connecting frame, and grippers for grasping the workpiece body are provided at both ends of the bottom surface of the connecting frame.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This production line realizes fully automated operations from screw preparation, oil pan screw assembly, air tightness testing, coding to product classification and transfer. Each link is closely connected, and there is no need for manual intervention for tedious operations, such as manual handling of oil pans, manual screw assembly and testing, which greatly shortens the production and testing cycle of each product.

[0019] 2. By taking photos of the screws with a CCD visual camera, it is possible to accurately determine whether there is a sealing ring on the screw. Only qualified screws will be captured by the electromagnetic adsorption head and used for the assembly of the oil pan. This precise detection and screening mechanism ensures that the quality of the screws assembled on the oil pan meets the requirements and reduces quality risks such as poor oil pan sealing caused by screw problems.

[0020] 3. Use the leak detection end to test the air tightness of the oil pan workpiece body after screws are assembled. This step can effectively detect whether the sealing performance of the oil pan meets the standard. In addition, the leak detection end can also perform coding processing on qualified products on the basis of accurate detection, which not only ensures product quality but also facilitates product quality traceability. At the same time, unqualified products will be accurately transferred to the top surface of the unqualified conveyor belt by the manipulator assembly at the bottom of the truss track for recycling, preventing unqualified products from mixing into qualified products and strictly controlling product quality.

[0021] 4. When the robot assembly parts are transferring products, they can operate accurately according to the set paths and actions, and can work continuously and stably in a high-intensity working environment, reducing failures and downtime in the production process.

[0022] In summary, the present invention overcomes the shortcomings of the prior art, can perform automated processing without investing a large amount of manpower costs, and the accuracy of the detected lines and detected data is improved, and has high social use value and application prospects.

[0042] A leak detector 2 for controlling the leak detection end 300 is provided at the top front side of the detection frame 1, and a data computer 3 is provided at the top right side of the detection frame 1. When the workpiece body 100 after screw sealing is transferred to the bottom of the leak detection end 300 through the transfer track B9, the moving seat B91 and the tooling fixture B92, the leak detector 2 can control the main cylinder 12 to open, so that the leak detection end 300 can perform an airtightness test on the workpiece body 100. An inkjet printer is provided inside the leak detection end 300 for performing inkjet coding on the workpiece body 100 after the airtightness test is qualified.

[0043] Specifically, refer to Figure 1 , Figure 6 and Figure 8 The top surface of the detection frame 1 is provided with a discharge track 11 whose end is connected to the detection frame 10, and the rear part of the top surface of the inner cavity of the detection frame 1 is provided with a truss track 131 for moving the workpiece body 100. The truss track 131 and the detection frame 1 are connected and fixed by a hanger 13. After the workpiece body 100 is inspected and qualified by the leak detection end 300, the qualified workpiece body 100 is transferred to the top surface of the qualified conveyor belt 41 by the cooperation between the discharge track 11 and the robot assembly 200 and the transfer track B9, the moving seat B91 and the tooling fixture B92 for subsequent appearance inspection.

[0044] Specifically, refer to Figure 8 The bottom end of the truss rail 131 is slidably connected with a connecting seat 132, and the bottom end of the connecting seat 132 and the bottom end of the discharge rail 11 are both provided with a manipulator assembly 200. After the holes on the workpiece body 100 are sealed with screws, the workpiece body 100 can be transferred to the bottom of the truss rail 131 by the cooperation of the transfer rail A8, the movable seat A81 and the tooling fixture A82, so that the manipulator assembly 200 can transfer the workpiece body 100 to the top surface of the movable seat B91 for the next step of air tightness detection processing, and the manipulator assembly 200 at the bottom of the truss rail 131 can transfer the workpiece body 100 that is detected as unqualified by the leak detection end 300 to the top surface of the unqualified conveyor belt 51 for subsequent unqualified recovery processing.

[0045] Specifically, refer to Figure 7 and Figure 8 The manipulator assembly 200 includes a top frame 2001 which is fixedly connected to the connecting seat 132 and slidably connected to the discharge track 11. A driver 2002 is provided at the top of the top frame 2001, and a connecting frame 2003 which is movably connected to the top frame 2001 is provided at the bottom of the output shaft of the driver 2002. The manipulator assembly 200 can move horizontally at the bottom of the truss track 131 and the discharge track 11.

[0046] Specifically, refer to Figure 6 and Figure 7 A de-energized electromagnet 2004 for positioning the workpiece body 100 is disposed at the bottom of the connecting frame 2003 , and grippers 2005 for grabbing the workpiece body 100 are disposed at both ends of the bottom surface of the connecting frame 2003 .

[0047] Working principle: First, pour the screws required for detection into the vibration plate 61 in the feed box 6. Inside the main detection frame 1 of the production line, the pad 601 plays a key supporting and connecting role. The feed rack 62 set on the top of the fixedly installed vibrator 602 receives the screws output by the vibration plate 61. Through the coordinated operation of the vibrator 602, the vibration plate 61 and the feed rack 62, the screws can be smoothly transported to the end of the feed rack 62. At this time, the electromagnetic adsorption head 64 at the output end of the horizontal drive cylinder 63 on the top surface of the pad 601 grabs the screws that arrive at the end of the feed rack 62. At the same time, the CCD visual camera 65 located directly below the end of the feed rack 62 takes a photo of the screws for detection. The main purpose is to determine whether there is a sealing ring on the screw. After the inspection is completed, the electromagnetic adsorption head 64 moves the qualified screws according to the inspection results and inserts them into the screw clamp 751 at the end of the pneumatic cylinder 75 at the bottom of the adjustment plate 72 in the upper torque mechanism 700, in preparation for subsequent assembly;

[0048] Place the oil pan workpiece body 100 to be inspected on the top surface of the moving seat A81. At this time, the upper torsion mechanism 700 starts to work, wherein the transverse driving seat 71, the adjustment plate 72, the linkage frame 73, and the screw gun 74 installed on the top surface of the support frame 7 on the inner bottom surface of the detection frame 1 work together to screw the screws in the screw fixture 751 into the holes opened on the surface of the oil pan workpiece body 100, completing the initial sealing of the oil pan for subsequent air tightness testing. The oil pan workpiece body 100 with the screws assembled is then transferred through the cooperation of the transfer track A8 and the moving seat A81, and is transferred to the bottom of the truss track 131, where it is grabbed and transferred by the manipulator assembly 200. At the same time, the transfer track B9 on the top surface of the detection frame 1 and the slidingly connected moving seat B91 and the tooling fixture B92 on the top surface of the moving seat B91 can also assume similar transfer functions, and the position of the oil pan can be flexibly transferred according to the production process requirements;

[0049] The workpiece body 100 is transferred by the manipulator assembly 200 located at the bottom of the truss track 131, so that the workpiece body 100 can be moved to the top surface of the moving seat B91, and then the workpiece body 100 is placed below the leak detection end 300 through the transfer track B9, the moving seat B91 and the tooling fixture B92, so that the leak detection end 300 performs airtightness detection on the workpiece body 100. The unqualified workpiece body 100 will be transferred again to the bottom of the truss track 131 through the transfer track B9, the moving seat B91 and the tooling fixture B92, and the unqualified workpiece body 100 will be grabbed by the manipulator assembly 200 and transferred to the top surface of the unqualified conveyor belt 51;

[0050] After the workpiece body 100 passes the air tightness test, the inkjet printer in the leak detection end 300 will perform inkjet coding on the qualified oil pan. The coding content may include information such as product batch and production date for subsequent traceability and management. Then, through the cooperation of the transfer track B9, the moving seat B91 and the tooling fixture B92, the robot assembly 200 at the bottom of the discharge track 11 grabs the qualified workpiece body 100, so that the qualified workpiece body 100 can be transferred to the top surface of the qualified conveyor belt 41 for subsequent appearance inspection process.

[0051] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
