Description

Technical Field

[0001] The present invention relates to the technical field of piston processing equipment, in particular to a material feeding detection station applied to a piston processing device. Background Art

[0002] The piston is a fundamental engine component, the heart of the engine. Currently, automotive pistons are being developed to achieve high strength, high wear resistance, high precision, low expansion, lightweight, and modular structures. A piston typically consists of an upper portion and a lower portion integrally formed at the bottom of the upper portion. During production, pistons are processed sequentially using lathes, drilling machines, and other processing equipment. Because the pistons are continuously sprayed with coolant during processing, after each processing unit completes a process, the pistons are removed and the coolant is blown off. The pistons are then placed in a testing device to verify that they have passed the process. Finally, qualified pistons are placed in the next processing unit for further processing, and this cycle repeats until the pistons are complete.

[0003] In the prior art, the above processes all require manual loading and unloading of materials, which is not only inefficient but also time-consuming, labor-intensive and labor-intensive.

[0004] Therefore, the present invention proposes a technical solution to solve the above-mentioned problem that manual loading and unloading is not only inefficient but also time-consuming, labor-intensive and labor-intensive. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a material feeding detection station applied to the piston processing device, aiming to achieve the technical effects of automatic loading and unloading, improving work efficiency, reducing labor intensity, and saving time and labor.

[0006] A material feeding detection station used in a piston processing device comprises a processing device body, a material feeding and conveying structure, a robotic arm, a water blowing detection structure and a material discharging transfer structure; The loading and conveying structure is located at the front side of the processing device body, and the loading and conveying structure includes a first base and a first conveyor belt body. The first conveyor belt body is installed on the first base and conveys from front to back. Two symmetrical limit plates are provided above the first conveyor belt body. The extension direction of the limit plates is consistent with the conveying direction of the first conveyor belt body. A flaring plate is fixed to the front end of the limit plate. The front end of the flaring plate is inclined outward. The limit plate and the flaring plate are both connected to the top end of the first base through an extension plate. The robotic arm is located between the loading and conveying structure and the processing device body, and is used to clamp the piston in the loading and conveying structure into the processing device body; The water blowing detection structure is located on the left side of the processing device body, and the water blowing detection structure includes a bracket, a box, a first linear module, a second linear module, a placement plate, a detection device, a defective product conveying structure, an air pump and a rodless cylinder. The bracket includes a top plate and several support rods fixed to the bottom end of the top plate, and a partition located below the top plate is fixedly connected between the several support rods. A first mounting seat is fixed to the rear side of the top end of the bracket, the first linear module is installed on the top end of the first mounting seat, and the front end of the first linear module extends horizontally forward to the front side of the bracket, and a first slide plate is fixed on the slider of the first linear module. The right end of the first slide plate extends to the right to the right side of the first linear module and is installed with a first clamping assembly, and a second mounting seat is fixed to the right side of the top end of the bracket. The lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism. The lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism. The lifting mechanism is a bottom end of the lifting mechanism, and the lifting mechanism is a bottom end of the lifting mechanism.

[0007] The box is fixed to the right side of the bracket and is located between the bracket and the processing device body. The box is a cylindrical structure with an open top. The placement plate is fixed at the opening of the box and corresponds to the bottom of the second clamping assembly. A plurality of through holes are opened on the placement plate. A fixing frame is fixed in the box. An air pump is installed on the fixing frame. An air pipe is connected to the air pump. A plurality of air blowing branches are connected to the air pipe. The rodless cylinder is mounted on the top of the bracket and extends horizontally to the left and right, and the slider of the rodless cylinder corresponds to the bottom of the second clamping assembly; The detection device is installed at the top of the bracket and is located on the left side of the first linear module. The detection device is lower than the height of the first linear module. The defective product conveying structure includes a second base and a second conveyor belt body, the second base is mounted on the top of the partition, the second conveyor belt body is mounted on the second base and conveys from front to back, the rear end of the second conveyor belt body extends backward and passes through the bracket, and the front end of the second conveyor belt body extends forward and passes through the bracket and corresponds to the bottom of the first clamping assembly; The discharging transfer structure is located in front of the water blowing detection structure, and its left end extends to the left to the next process. The discharging transfer structure is a chain guide ring conveyor line.

[0008] By adopting the above technical solution, workers place the piston in an upright position with its lower portion facing downward on the first conveyor belt body. The first conveyor belt body rotates, driving the piston backward. The piston passes between two expansion plates. The expansion plates can expand the entrance of the gap formed between the two limit plates. When placing the piston, workers do not need to deliberately face the gap formed between the two limit plates, which improves the efficiency of piston placement. The gap formed between the two limit plates allows the lower part of the piston to pass through at a specific angle. When the piston enters the gap formed between the two limit plates, the piston is positioned.

[0009] The piston is then taken into the processing device body by a robotic arm for processing. After processing is completed, the robotic arm takes out the piston and places it on a placement plate between the air blowing branches.

[0010] Then the air pump is started to blow air, and the air is blown out through the air pipe and the air branch pipe, thereby drying the coolant remaining on the piston after being processed by the processing device body.

[0011] The second gripping assembly then grips the piston, and the second linear module moves the second slide to the left. The second slide drives the second gripping assembly to move leftward, and the second gripping assembly drives the piston to move leftward until the piston is directly above the slider of the rodless cylinder.

[0012] Then, the piston is placed on the slider of the rodless cylinder through the second clamping assembly. Then the rodless cylinder is started, and the slider of the rodless cylinder slides to the left, thereby driving the piston to move to the left until the piston is directly below the first clamping assembly.

[0013] The first gripping assembly then grips the piston, and the first linear module moves the first slide backward. The first slide drives the first gripping assembly backward, which in turn drives the piston backward until the piston is aligned with the inspection device. The piston is then placed on the bracket, facing the right side of the inspection device. The inspection device then performs an inspection.

[0014] After the inspection is complete, if the piston fails, the first gripper assembly grasps it and moves it forward via the first linear module until it is directly above the front end of the second conveyor belt body. The first gripper assembly then places the piston on the second conveyor belt body. The second conveyor belt body rotates, transporting the failed piston backward. A worker standing behind the water-blowing inspection structure removes it. If the piston passes, the first gripper assembly grasps it and moves it forward via the first linear module until it is directly above the chain guide loop conveyor line. The first gripper assembly then places the piston on the slider of the chain guide loop conveyor line.

[0015] Finally, a chain-guided circular conveyor line transports the piston to the next process, which also includes a robotic arm, corresponding processing equipment, corresponding water-blowing detection structure, and corresponding chain-guided circular conveyor line.

[0016] The first and second gripping assemblies operate as follows: When the pneumatic cylinder is activated, the cylinder's piston rod retracts, driving the lifting plate downward. The lifting plate then drives the lifting rod downward. The lifting rod drives the mounting plate downward. The mounting plate then drives the pneumatic gripper downward. After the pneumatic gripper clamps the piston, the cylinder's piston rod extends, gripping the piston upward.

[0017] The present invention can realize full automation during piston processing, realize automatic loading and unloading between various working procedures, improve work efficiency, reduce labor intensity, and save time and labor.

[0018] The present invention is further configured as follows: a first baffle located above the first conveyor belt body is fixed to the top end of the rear side of the first base, and a second baffle located above the second conveyor belt body is fixed to the top end of the rear side of the second base.

[0019] By adopting the above technical solution, the provision of the first baffle and the second baffle can prevent the piston from falling from the first conveyor belt body and the second conveyor belt body.

[0020] The present invention is further configured as follows: the top of the placement plate, the top of the bracket, the top of the slider of the rodless cylinder, and the top of the slider of the chain guide ring conveyor line are all installed with a mold that can be used for the piston to be mounted on the outside in a matching connection manner. The mold on the top of the bracket corresponds to the right side of the detection equipment and corresponds to the bottom of the first clamping component.

[0021] By adopting the above technical solution, the mold on the top of the placement plate can prevent the piston from being blown over during drying. The mold on the top of the bracket can ensure that the piston does not tilt when the detection equipment is testing the piston. The mold on the top of the slider of the rodless cylinder and the mold on the top of the slider of the chain guide ring conveyor both play a role in preventing the piston from falling off.

[0022] The present invention is further configured as follows: a liquid outlet is provided at the bottom end of the box body, and a waste liquid collection box corresponding to the liquid outlet is provided below the box body.

[0023] By adopting the above technical solution, the waste liquid in the box body enters the waste liquid collection box through the liquid outlet, which facilitates the collection of the waste liquid.

[0024] The present invention is further configured as follows: a plurality of fixing blocks are fixed to the top of the first base, and one end of the extension plate away from the limiting plate passes through the fixing block in a sliding connection and is tightened by a bolt.

[0025] By adopting the above technical solution, the extension plate can be slid along the fixed block by loosening the bolts, and the extension plate drives the limit plate to move, thereby adjusting the spacing distance between the two limit plates according to pistons of different sizes.

[0026] A further configuration of the present invention is that scale lines are provided on the extension plate.

[0027] By adopting the above technical solution, the limit plate can be quickly adjusted to a suitable position by observing the side wall of the fixed block and the corresponding index on the scale line.

[0038] Furthermore, scale lines 36 are provided on the extension plate 7. By observing the corresponding indexes on the side wall of the fixed block and the scale lines 36, the limiting plate 5 can be quickly adjusted to a suitable position.

[0039] Working Principle: A worker places the piston on the first conveyor belt body 4 in an upright position with its lower part facing downward. The first conveyor belt body 4 rotates, driving the piston backward. The piston passes between two flaring plates 6. The flaring plates 6 are designed to widen the entrance to the gap formed between the two limit plates 5. When placing the piston, the worker does not need to deliberately face the gap formed between the two limit plates 5, which improves the worker's efficiency in placing the piston. The gap formed between the two limit plates 5 allows the lower part of the piston to pass through at a specific angle. When the piston enters the gap formed between the two limit plates 5, the piston is positioned.

[0040] Then, the piston is clamped by the robot arm 2 and placed in the processing device body 1 for processing. After the processing is completed, the robot arm 2 takes out the piston and places it on the placement plate 12 and between the air blowing branches 34.

[0041] Then start the air pump 15, the air pump 15 blows air, and the air passes through the air pipe 33 and is blown out from the air blowing branch pipe 34. Thereby, the coolant remaining on the piston after being processed by the processing device body 1 is blown dry.

[0042] Then, the second gripping assembly 25 grips the piston, and the second slide 24 is moved leftward by the second linear module 11. The second slide 24 drives the second gripping assembly 25 to move leftward, and the second gripping assembly 25 drives the piston to move leftward until the piston is directly above the slider of the rodless cylinder 2616.

[0043] The piston is then placed on the slider of the rodless cylinder 2616 by the second gripping assembly 25. The rodless cylinder 2616 is then started, and the slider of the rodless cylinder 2616 slides to the left, thereby driving the piston to move to the left until the piston is directly below the first gripping assembly 22.

[0044] The first gripping assembly 22 then grips the piston, and the first slide 21 is moved backward by the first linear module 10. The first slide 21 drives the first gripping assembly 22 backward, which in turn drives the piston backward until the piston is aligned with the detection device 13. The piston is then placed on the bracket 8, facing the right side of the detection device 13. The detection device 13 then performs an inspection on it.

[0045] After the inspection is complete, if the piston fails, the first gripper assembly 22 grips the piston and the first linear module 10 moves it forward until it is directly above the front end of the second conveyor body. The first gripper assembly 22 then places the piston on the second conveyor body. The second conveyor body rotates, transporting the failed piston backward. A worker standing behind the water blow test structure removes the piston. If the piston passes, the first gripper assembly 22 grips the piston and the first linear module 10 moves it forward until it is directly above the chain guide loop conveyor 38. The first gripper assembly 22 then places the piston on the slider of the chain guide loop conveyor 38.

[0046] Finally, the piston is transported to the next process by the chain guide ring conveyor line 38. The next process is also provided with a robot arm 2, a corresponding processing device, a corresponding water blowing detection structure and a corresponding chain guide ring conveyor line 38.

[0047] The operating principle of the first and second gripping assemblies 22 and 25 is as follows: When the pneumatic cylinder 26 is activated, the piston rod of the cylinder 26 contracts, driving the lifting plate 27 downward. The lifting plate 27 drives the lifting rod 28 downward. The lifting rod 28 drives the mounting plate 29 downward. The mounting plate 29 drives the pneumatic gripper 30 downward. After the pneumatic gripper 30 clamps the piston, the piston rod of the cylinder 26 extends, gripping the piston upward.
