Description

Technical Field

[0001] This invention relates to the field of piston head production line transportation, and more specifically to a barge lifting AGV vehicle used in piston head production lines. Background Technology

[0002] In the modern production line of piston heads, the automation and intelligence of the flow between processes are the key links to improve overall efficiency and product quality. As the core precision component of the engine, the manufacturing process of piston heads usually involves multiple processes such as turning, grinding, welding, cleaning and storage. Frequent material transfer is required between these processes. At present, the transfer operations between production lines are mainly realized by AGV vehicles.

[0003] Existing AGV vehicles typically only perform fixed-point transportation of piston heads between workstations or between workstations and warehouses. However, after processes such as welding and turning, the piston heads often have residual heat or debris on their surface. Directly transporting them to the next process or storing them in the warehouse would not only affect the quality of subsequent processing but also pose a risk of pollution to the storage environment. Therefore, we propose a barge-lifting AGV vehicle for piston head production lines. Summary of the Invention

[0004] The purpose of this invention is to provide a transport and lifting AGV vehicle for piston head production lines. It solves the technical problem that existing AGV vehicles can usually only complete the fixed-point transportation function of piston heads between workstations or between workstations and warehouses. However, after the piston heads have undergone processes such as welding and turning, their surfaces often have a certain amount of residual processing heat or residual processing debris. If they are directly transported to the next process or stored in the warehouse, it will not only affect the quality of subsequent processing, but also pose a risk of pollution to the storage environment.

[0005] The present invention achieves the above objectives through the following technical solutions: A transport and lifting AGV vehicle for piston head production lines includes an AGV body, with a steering wheel mechanism and a moving wheel mechanism respectively located at both ends of the bottom of the AGV body. The AGV body has a support plate connected to its top via a lifting mechanism. An inflation unit, pulsatingly connected to the moving wheel mechanism, is located inside the AGV body. The inflation unit is connected to an air storage cylinder via a one-way air outlet pipe. The inflation unit injects gas into the air storage cylinder when the moving wheel mechanism rotates. The air storage cylinder is located on the AGV body below the support plate. Supports are located at both the upper and lower ends of the air storage cylinder. A piston plate is movably mounted inside the air storage cylinder, between the upper and lower supports. An exhaust connection pipe is inserted through the piston plate. A solenoid valve is located inside the exhaust connection pipe. The bottom end of the exhaust connection pipe extends below the lower support, and its top end is connected to a jet pipe via a pipe. A detection element for supporting the piston head component and located inside the jet pipe is embedded in the support plate. When the detection element detects the piston head component, it controls the solenoid valve to open.

[0006] A further improvement is that the moving wheel mechanism includes a wheel frame located at the bottom of the AGV body, a wheel axle located within the wheel frame, moving wheels located at both ends of the wheel axle, a rotating device located within the AGV body, and a transmission component for connecting the output end of the rotating device and the wheel axle. The inflation unit includes an air cylinder component disposed within the AGV vehicle body, a piston component movably disposed within the air cylinder component, a cam fixedly sleeved on the output end of the rotating device, a contact rod connected at one end to the piston component, the other end of the contact rod slidingly contacting the outer wall of the cam, and an elastic component sleeved on the outer wall of the contact rod for driving the contact rod to contact the cam. The air cylinder component is connected to one end of a one-way air outlet pipe, and the air cylinder component is connected to a filter component through a one-way air inlet pipe. The filter component is disposed on the AGV vehicle body.

[0007] A further improvement is that a return spring is sleeved on the outer wall of the exhaust connection pipe, one end of the return spring is connected to the upper bracket, and the other end is connected to the piston plate. The upper bracket is equipped with a detection sensor 2 for detecting the position of the piston plate. The air cylinder is slidably mounted inside the AGV vehicle body. The air cylinder is connected to the output end of the telescopic device located inside the AGV vehicle body. It is driven to move horizontally by the telescopic device. The telescopic device is electrically connected to the second detection sensor. When the second detection sensor detects that the piston plate has moved upward to a preset position, it controls the telescopic device to move the air cylinder away from the rotating device, so that the contact rod disengages from the cam.

[0008] A further improvement is that the detection component includes a groove formed on the top of the support plate, a movable plate inserted into the groove, an elastic connector connecting the movable plate and the bottom of the groove, and a detection sensor one disposed at the bottom of the groove, wherein the detection sensor one controls a solenoid valve one to open when it contacts the movable plate.

[0009] A further improvement is that the barge lifting AGV vehicle also includes clamping mechanisms symmetrically arranged on both sides of the top of the support plate, the clamping mechanisms being used to clamp the piston head component on the movable plate; The clamping mechanism includes a mounting plate slidably mounted on a support plate, an arc-shaped clamping plate connected to the mounting plate, and a pneumatic telescopic rod with one end connected to the support plate via a mounting base and the other end connected to the mounting plate.

[0010] A further improvement is that the air inlet end of the pneumatic telescopic rod is connected to a distributor via a pipeline. The distributor is located on the support plate and is connected to the top of the exhaust connection pipe via a telescopic pipe. Several sets of jet pipes are provided and are all located on the clamping plate. The several sets of jet pipes are connected to the pneumatic telescopic rod via a connecting pipeline, and a pressure relief valve is provided in the connecting pipeline. The air outlet end of the pneumatic telescopic rod is provided with an exhaust pipe, and a second solenoid valve is provided in the exhaust pipe. The second solenoid valve closes when the first detection sensor contacts the movable plate.

[0011] A further improvement is that a connecting screw is inserted into the mounting plate, one end of the connecting screw is connected to the clamping plate, and the other end is threaded with a limiting nut. A buffer spring is fitted on the outer wall of the connecting screw at a position between the mounting plate and the clamping plate.

[0012] A further improvement is that the jet pipe is L-shaped, and the inner walls of both the vertical and horizontal sections of the jet pipe are provided with several sets of interconnected jet nozzles.

[0013] The beneficial effects of this invention are as follows: This invention integrates an inflation unit that is linked to the moving wheel mechanism within the AGV body. This unit automatically generates compressed gas during transport and stores it in an air tank. When the detection component on the carrier plate detects the piston head component, it triggers the opening of a solenoid valve, allowing the stored gas to cool and clean the piston head component through an air jet pipe. This effectively solves the technical problem of residual processing heat and debris on the surface of the piston head component, which affects the quality of subsequent processes and pollutes the storage environment. Workpiece processing can be completed during the transfer process, improving the cleanliness of the production line and the efficiency of process connection. At the same time, it does not require a separate air-cooling system, reducing energy consumption and operating costs. Attached Figure Description

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1 Please see the appendix Figure 1-3 A type of AGV vehicle for transporting and lifting piston head production line includes an AGV body 1. The bottom ends of the AGV body 1 are respectively provided with a steering wheel mechanism 2 and a moving wheel mechanism 3. The steering wheel mechanism 2 is a conventional mechanism in the art and is used to control the movement direction of the AGV body 1, which will not be described in detail here. The moving wheel mechanism 3 is used to move the AGV body 1 to realize the transport of piston head components. The top of the AGV body 1 is connected to a support plate 5 via a lifting mechanism 4. In this embodiment, the lifting mechanism 4 can be several sets of electric telescopic rods or scissor-type telescopic frames, etc. The AGV body 1 is equipped with an inflation unit that is connected to the moving wheel mechanism 3. The inflation unit is connected to the air storage cylinder 9 through a one-way air outlet pipe. The inflation unit is used to inject gas into the air storage cylinder 9 when the moving wheel mechanism 3 rotates. In this embodiment, the one-way air outlet pipe is a pipe with a one-way valve inside. The AGV body 1 is transported under the action of the moving wheel mechanism 3, and the rotation of the moving wheel mechanism 3 causes the inflation unit to work, thereby injecting gas with a certain pressure into the air storage cylinder 9. An air storage cylinder 9 is mounted on the AGV body 1 and located below the support plate 5. Supports are provided at both the upper and lower ends of the air storage cylinder 9. In this embodiment, the support includes a ring frame and a transverse frame fixed within the ring frame. A piston plate 10 is movably mounted inside the air storage cylinder 9 and located between the upper and lower supports. The diameter of the piston plate 10 is adapted to the inner diameter of the air storage cylinder 9. In this embodiment, a wear-resistant rubber sealing ring is embedded in the outer wall of the piston plate 10 and contacts the inner wall of the air storage cylinder 9. An exhaust connection pipe 11 is inserted through the piston plate 10. This exhaust connection pipe 11 is a rigid pipe. A solenoid valve is installed inside the exhaust connection pipe 11. The bottom end of the exhaust connection pipe 11 extends below the lower support, and its top end is connected to a jet pipe 6 via a pipe. A detection element for supporting the piston head component and located inside the jet pipe 6 is embedded on the support plate 5. When the detection element detects the piston head component, it controls the solenoid valve 1 to open. Considering that in the piston head production line, AGV vehicles typically travel to piston head processing equipment (such as welding equipment, turning equipment, etc.) to pick up piston head components held by robotic arms and transport them to locations such as automated warehouses, after the piston head component is placed on the carrier plate 5 by the robotic arm, the detection component detects the piston head component and controls the solenoid valve to open. At this time, the gas pre-stored in the air tank 9 by the inflation section enters the jet pipe 6 through the exhaust connection pipe 11 and is then ejected from the jet pipe 6. The gas ejected from the jet pipe 6 can not only improve the bearing capacity but also... The remaining heat on the piston head component on plate 5 is cooled down, and residual debris adhering to the piston head component is blown away, which plays a certain role in cleaning the piston head component. This lays a good quality foundation for the subsequent storage or use of the piston head component. Furthermore, due to the use of an air-filled unit, during the operation of the AGV vehicle, whether it is driving empty or transporting the piston head component, the air-filled unit can continuously and automatically replenish compressed gas into the air storage tank 9, so that the air storage tank 9 always maintains a certain sufficient air supply, without relying on an independent air-cooling system, thus reducing energy consumption and operating costs.

[0018] Preferably, the moving wheel mechanism 3 of this embodiment includes a wheel frame disposed at the bottom of the AGV body 1, a wheel axle disposed in the wheel frame, moving wheels disposed at both ends of the wheel axle, a rotating device 12 disposed in the AGV body 1, and a transmission component for drivingly connecting the output end of the rotating device 12 and the wheel axle. In this embodiment, the rotating device 12 is such as a motor, and the transmission component can be a sprocket drive assembly (including sprockets and chains, etc.). The inflation unit includes an air cylinder 14 housed within the AGV body 1, a piston 16 movably housed within the air cylinder 14, a cam 13 fixedly fitted onto the output end of the rotating device 12, a contact rod 15 connected at one end to the piston 16, the other end of the contact rod 15 slidingly contacting the outer wall of the cam 13, and an elastic element fitted onto the outer wall of the contact rod 15 for driving the contact rod 15 to contact the cam 13. The air cylinder 14 is connected to one end of a one-way air outlet pipe, and the air cylinder 14 is connected to a filter 26 via a one-way air inlet pipe. The filter 26 is located within the AGV body 12. On the V-shaped body 1, in this embodiment, a pulley is provided at one end of the contact rod 15 to slide in contact with the outer wall of the cam 13, thereby reducing the wear between the two. In this embodiment, the elastic element can be a spring, with one end connected to the outer wall of the contact rod 15 and the other end connected to the outer wall of the air cylinder 14. In this embodiment, the filter element 26 includes, for example, a filter housing connected to a one-way air intake pipe, an activated carbon filter screen disposed inside the filter housing, and several sets of vent holes opened on one side of the outer wall of the filter housing. In this embodiment, the one-way air intake pipe is a pipe with a one-way valve inside. The rotating device 12 drives the wheel axle to rotate through the transmission component, thereby realizing the movement of the AGV body 1. At the same time, the rotating device 12 synchronously drives the cam 13 to rotate, and the cam 13 periodically pushes the contact rod 15 with the contour of the cam 13. With the reset cooperation of the elastic component, the contact rod 15 drives the piston 16 to reciprocate in the air cylinder 14. When the piston 16 returns, the external air is purified by the filter 26 and then drawn into the air cylinder 14 through the one-way air inlet pipe. When the piston 16 advances, it compresses the gas and continuously presses it into the air storage cylinder 9 through the one-way air outlet pipe and accumulates below the piston plate 10. As the compressed gas is continuously input, the air pressure in the air storage cylinder 9 gradually increases, pushing the piston plate 10 to move upward.

[0019] Preferably, the jet pipe 6 in this embodiment is L-shaped. The inner wall of the vertical section and the inner wall of the horizontal section of the jet pipe 6 are provided with several sets of interconnected jet nozzles. The height of the jet pipe 6 is greater than the height of the piston head component to be transported. The L-shaped design of the jet nozzles can form a circumferential surround from above and to the side of the piston head component, so that the gas can be evenly covered on the outer surface of the piston head component through the jet nozzles, thereby achieving efficient cooling and cleaning of the piston head component.

[0020] Example 2 Please see the appendix Figure 2-4 Based on Embodiment 1, the outer wall of the exhaust connecting pipe 11 in this embodiment is fitted with a return spring. One end of the return spring is connected to the upper bracket, and the other end is connected to the piston plate 10. The return spring is used to drive the piston plate 10 to move downward when the gas in the gas storage cylinder 9 below the piston plate 10 decreases. The upper support is equipped with a second detection sensor 18 for detecting the position of the piston plate 10. In this embodiment, the second detection sensor 18 can be a laser rangefinder sensor, but it is not limited to this type. The air cylinder 14 is slidably disposed inside the AGV body 1. In this embodiment, a slider is provided on the outer wall of the air cylinder 14, and a slide rail that cooperates with the slider is provided on the inner wall of the AGV body 1. The slide rail is parallel to the length direction of the AGV body 1. The air cylinder 14 is connected to the output end of the telescopic device 17 disposed inside the AGV body 1, and is driven to move horizontally by the telescopic device 17. In this embodiment, the telescopic device 17 can be an electric telescopic rod. The telescopic device 17 is electrically connected to the second detection sensor 18. When the second detection sensor 18 detects that the piston plate 10 has moved upward to a preset position, it controls the telescopic device 17 to drive the air cylinder 14. 4. Move away from the rotating device 12 to make the contact rod 15 disengage from the cam 13. The user can preset the detection position of the detection sensor 2 18. When the AGV body 1 moves, the inflation part continuously injects gas into the air tank 9 to push the piston plate 10 upward. After the piston plate 10 reaches the preset position, the detection sensor 2 18 triggers a signal to control the telescopic device 17 to drive the air cylinder component 14 to move away from the rotating device 12, so that the cam 13 completely disengages from the contact rod 15, thereby interrupting the inflation action, effectively preventing the gas in the air tank 9 from being overcharged, and ensuring the overall safe operation. It should be noted that in this embodiment, the second detection sensor 18, the detection component, the telescopic device 17, the first solenoid valve, and the rotating device 12 are all connected to the controller. The controller can be located on the AGV body 1. For example, after the detection component detects the piston head component, it sends a signal to the controller, and then the controller controls the first solenoid valve. When the second detection sensor 18 detects that the piston plate 10 has reached a preset position, it sends a signal to the controller, and then the controller controls the telescopic device 17.

[0021] Example 3 Please see the appendix Figure 4 Based on Embodiment 1, the detection component of this embodiment includes a groove formed on the top of the support plate 5, a movable plate 7 inserted in the groove, an elastic connector connecting the movable plate 7 and the bottom of the groove, and a detection sensor 8 disposed at the bottom of the groove. When the detection sensor 8 contacts the movable plate 7, it controls the opening of the solenoid valve. In this embodiment, the elastic connector is a spring, and the detection sensor 8 in this embodiment can be a pressure sensor, which is electrically connected to the controller. After the piston head component is placed on the movable plate 7, under the gravity of the piston head component, the movable plate 7 presses down to make the elastic connector contact the detection sensor 8, and then the detection sensor 8 sends a signal to the controller. The controller controls the solenoid valve to open, so that the gas in the gas storage tank 9 enters the exhaust connection pipe 11.

[0022] Example 4 Please see the appendix Figure 1-4Based on embodiment 3, the AGV vehicle of this embodiment also includes clamping mechanisms symmetrically arranged on both sides of the top of the support plate 5. The clamping mechanisms are used to clamp the piston head component on the movable plate 7 to ensure the stability of the piston head component during the vehicle transport process and prevent it from falling off the vehicle. The clamping mechanism includes a mounting plate 23 slidably disposed on the support plate 5, an arc-shaped clamping plate 20 connected to the mounting plate 23, and a pneumatic telescopic rod 22 with one end connected to the support plate 5 via a mounting seat and the other end connected to the mounting plate 23. The pneumatic telescopic rod 22 is a conventional structure in the art. In this embodiment, the pneumatic telescopic rod 22 includes a sealing cylinder fixed on the mounting seat, a piston rod with one end inside the sealing cylinder and the other end connected to the mounting plate 23, and an elastic member connecting the piston rod and the inner wall of one side of the sealing cylinder. The sealing cylinder is provided with an air inlet and an air outlet. After the piston head component is placed on the movable plate 7, air is injected into the pneumatic telescopic rod 22, which in turn drives the mounting plate 23. The mounting plate 23 drives the clamping plate 20 to clamp the piston head component, thus restricting the piston head component on the movable plate 7.

[0023] Preferably, in this embodiment, the air inlet of the pneumatic telescopic rod 22 is connected to a distributor 19 via a pipeline. The distributor 19 is used to evenly distribute the gas discharged from the exhaust connection pipe 11 into the pneumatic telescopic rod 22. The distributor 19 is located on the support plate 5 and is connected to the top of the exhaust connection pipe 11 via a telescopic pipe. Several sets of jet pipes 6 are provided and are all located on the clamping plate 20, so that the jet pipes 6 move with the clamping plate 20. In the non-working state, a reasonable distance is maintained between the clamping plate 20 and the movable plate 7, providing an unobstructed operating space for the external robotic arm, facilitating its precise handling of the piston head components. Several sets of jet pipes... All air pipes 6 are connected to the pneumatic telescopic rod 22 through a connecting pipe 21, and a pressure relief valve is provided in the connecting pipe 21. The gas in the air storage cylinder 9 flows sequentially through the exhaust connecting pipe 11, telescopic pipe, distributor 19 and pipeline into the pneumatic telescopic rod 22, which first drives the piston rod in the pneumatic telescopic rod 22 to move, thereby driving the clamping plate 20 to perform the clamping operation of the piston head component. As air is continuously injected, the pressure inside the pneumatic telescopic rod 22 increases. When the pressure inside the pneumatic telescopic rod 22 exceeds the set threshold of the pressure relief valve, the pressure relief valve automatically opens, allowing the excess gas to be diverted to each jet pipe 6 through the connecting pipe 21, ultimately forming a directional jet airflow. The pneumatic telescopic rod 22 has an exhaust pipe 25 at its outlet end. The exhaust pipe 25 contains a solenoid valve 2. The solenoid valve 2 closes when the detection sensor 8 contacts the movable plate 7. The solenoid valve 2 is electrically connected to the controller. When the solenoid valve 2 closes, it ensures that the gas entering the pneumatic telescopic rod 22 is sealed, thereby maintaining a stable clamping state. When the detection sensor 8 does not contact the movable plate 7, the solenoid valve 2 remains open, allowing the interior of the pneumatic telescopic rod 22 to communicate with the atmosphere and return to its initial state.

[0024] Preferably, in this embodiment, a connecting screw 24 is inserted into the mounting plate 23. One end of the connecting screw 24 is connected to the clamping plate 20, and the other end is threaded with a limiting nut. Through the connecting screw 24 and the limiting nut, the clamping plate 20 can be adjusted and easily disassembled and replaced to adapt to piston head components of different specifications. A buffer spring is sleeved on the outer wall of the connecting screw 24 at the position between the mounting plate 23 and the clamping plate 20. One end of the buffer spring abuts against the mounting plate 23, and the other end abuts against the clamping plate 20, so that the clamping plate 20 elastically clamps the piston head component, realizing adaptive buffer protection during the clamping process of the piston head component, and is not easy to damage the piston head component.

[0025] The above embodiments are merely illustrative of several implementations of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
