[0044] DETAILED DESCRIPTION

[0045] The specific embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of the present application.

[0046] Figure 6Figure 1 is a partial pneumatic circuit diagram of a vacuum handling system according to an embodiment of the present application. In an embodiment of the present application, the system can include a gas source processing element N, a pneumatic block P, a first air control valve Q, a vacuum generator F, a vacuum chuck I, an adsorption button A, a release button B, a pneumatic hoist M, and a lifting button E. The gas source processing element N can process compressed air, filter and reduce the pressure of the compressed air. One end of the pneumatic block P can be connected to the gas source processing element N to divide the air signal from the gas source processing element N into multiple. The first port (port 1) of the first air control valve Q can be connected to the first port (port 1) of the pneumatic block P. One end of the vacuum generator F can be connected to the fourth port (port 4) of the first air control valve Q to generate negative pressure according to the air signal from the first air control valve Q. The vacuum chuck I can be connected to the other end of the vacuum generator F and can be connected to the second port (port 2) of the first air control valve Q to adsorb or release a torque converter. The first port (port 1) of the adsorption button A can be connected to the second port (port 2) of the pneumatic block P, and the second port (port 2) of the adsorption button A can be connected to the fourteenth port (port 14) of the first air control valve for starting to input the air signal to the vacuum generator F through the fourth port of the first air control valve Q, and the vacuum generator F can generate negative pressure after receiving the air signal, so that the vacuum chuck I connected to the vacuum generator F can adsorb the torque converter. The first port (port 1) of the release button B can be connected to the first port of the adsorption button A, and the second port (port 2) of the release button B can be connected to the twelfth port (port 12) of the first air control valve Q for starting to input the air signal to the vacuum chuck I through the second port of the first air control valve Q to release the torque converter by breaking the vacuum environment of the vacuum chuck I. The first port (port 1) of the common button C can be connected to the second port of the pneumatic block P, and the second port (port 2) of the common button C can be connected to the first ports of the adsorption button A and the release button B for starting to realize the function that the adsorption button A and the release button B can be started. The pneumatic hoist M can be connected to the third port (port 3) of the pneumatic block P to lift or lower the vacuum chuck I. The first port (port 1) of the lifting button E can be connected to the third port of the pneumatic block P, and the second port (port 2) of the lifting button E can be connected to the pneumatic hoist M for controlling the pneumatic hoist M to lift or lower the vacuum chuck I.

[0047] The air source processing element can further process the compressed air to avoid impurities in the compressed air affecting the smoothness of the air path. The air distribution block P can be connected with the air source processing element N to receive the compressed air transmitted by the air source processing element N. The compressed air can be a gas signal. The air distribution block P can divide the received compressed air into multiple air paths, connect other components, and supply air. The first air control valve Q can serve as an execution control valve for vacuum adsorption and release. When the hydrodynamic torque converter needs to be adsorbed, the adsorption button A can be pressed to obtain the gas signal from the second port of the air distribution block P and deliver the gas signal to the fourteenth port of the first air control valve Q. Thus, the gas signal obtained by the first air control valve Q can be delivered from the fourth port of the first air control valve Q to the vacuum generator F, which can generate negative pressure, thereby enabling the vacuum chuck I connected thereto to adsorb the hydrodynamic torque converter. The second port of the release button B can be connected with the twelfth port of the first air control valve Q. When the hydrodynamic torque converter needs to be released, the release button B can be pressed to enable the gas signal of the release button B to reach the twelfth port of the first air control valve Q, so that the gas signal obtained by the first air control valve Q can be input from the second port of the first air control valve Q to the vacuum chuck I, which can destroy the vacuum environment in the vacuum chuck I, thereby enabling the vacuum chuck I to lower the hydrodynamic torque converter. The pneumatic hoist M can be connected with the third port of the air distribution block P, and the first port of the lifting button E can be connected with the third port of the air distribution block P. The second port can be connected with the pneumatic hoist M to control the lifting or lowering of the pneumatic hoist M, thereby enabling the vacuum chuck I to move in the vertical direction. Since the vacuum chuck I can adsorb the object to be detected, after the vacuum chuck I adsorbs the object to be detected, the lifting button E can control the lifting or lowering of the object to be detected. After the pneumatic hoist M lifts the hydrodynamic torque converter, it can move to a designated position and then lower it to complete the carrying work.

[0048] When carrying the hydrodynamic torque converter, the adsorption or release of the hydrodynamic torque converter can be controlled by the adsorption button A and the release button B. However, the staff may accidentally touch the adsorption button A or the release button B during work, which may cause the hydrodynamic torque converter to be accidentally adsorbed or released. Therefore, the system can further include a common button C. When the hydrodynamic torque converter needs to be adsorbed or released, the common button C must be pressed first. After the gas signal of the common button C is delivered to the release button B and the adsorption button A, the release button B and the adsorption button A can realize the functions of release and adsorption, thereby avoiding the risk of accidental touch by the staff during work.

[0049] When carrying the hydrodynamic torque converter, the hydrodynamic torque converter may be suspended in the air. At this time, the pneumatic hoist M may be lowered under the action of the gravity of the hydrodynamic torque converter, which may affect the work and safety of the staff. Therefore, in one embodiment of the present application, as shown in Figure 1As shown, the system can further include a balance block L. One end of the balance block L can be connected with the pneumatic hoist M, and the other end can be connected with the third port of the gas distribution block P. One side of the balance block L can also be connected with the first port and the second port of the lifting button E. The side of the balance block L connected with the first port and the second port of the lifting button E allows the lifting button E to control the pneumatic hoist M to rise or fall through the balance block L. The balance block L can make the hydraulic torque converter hover stably in the air when the pneumatic hoist M pulls the hydraulic torque converter to stop in the air, and can prevent the pneumatic hoist M from suddenly falling under the gravity of the hydraulic torque converter when the pneumatic hoist M pulls the hydraulic torque converter.

[0050] When the hydraulic torque converter is being carried, the worker may touch the release button B by mistake, which can cause a serious safety accident if the hydraulic torque converter is released. Therefore, in an embodiment of the present application, as shown, Figure 1 As shown, the system can further include a pressure detection valve K and a second air control valve J. The first port (port 1) of the pressure detection valve K can be connected with the second port of the gas distribution block P, and the second port (port 2) of the pressure detection valve K can be connected with the pneumatic hoist M to detect whether the pneumatic hoist M is loaded. The first port (port 1) of the second air control valve J can be connected with the second port of the release button B, and the second port (port 2) of the second air control valve J can be connected with the twelfth port of the first air control valve Q. The twelfth port (port 12) of the second air control valve J is connected with the third port (port 3) of the pressure detection valve K. When the hydraulic torque converter is being carried, the air pressure of the pneumatic hoist M is higher than that when the hydraulic torque converter is not being carried. At this time, the air signal in the pneumatic hoist M is fed back to the pressure detection valve K through the second port of the pressure detection valve K. When the pressure detection valve K receives the air signal sent by the pneumatic hoist M, the pressure detection valve K does not send the air signal to the twelfth port of the second air control valve J. When the second air control valve J does not receive the air signal from the pressure detection valve K, the first port of the second air control valve J does not output the air signal to the first air control valve Q even if the second port of the release button B receives the air signal. Therefore, the second port of the first air control valve Q does not output the air signal, and the hydraulic torque converter is not released, which avoids safety accidents caused by the release button B being touched by mistake during the carrying process. When the hydraulic torque converter is carried to the assembly line, the pressure in the pneumatic hoist M decreases to the state before the hydraulic torque converter is carried. At this time, the pressure detection valve K does not receive the air signal from the pneumatic hoist M, and the air signal of the pressure detection valve K is output to the twelfth port of the second air control valve J. When the second port of the release button B outputs the air signal to the first port of the second air control valve J, the second air control valve J outputs the air signal to the twelfth port of the first air control valve Q. The air signal of the first air control valve Q is output to the vacuum suction cup I through the second port, which breaks the vacuum state of the vacuum suction cup I and releases the hydraulic torque converter.

[0051] In one embodiment of the present application, as shown in Figure 1 The system can further include a shuttle valve R, a third port (port 3) of the shuttle valve R can be connected with a second port of the suction button A. A second port (port 2) of the shuttle valve R can be connected with a fourteenth port of the first pneumatic valve Q, and a first port (port 1) of the shuttle valve R can be connected with a fourth port of the first pneumatic valve Q. When the torque converter is suctioned by pressing the suction button A, the air signal of the suction button A is input to the shuttle valve R through the third port of the shuttle valve R, the second port of the shuttle valve R outputs the air signal to the first pneumatic valve Q, and then the air signal of the first pneumatic valve Q is output to the vacuum generator F through the fourth port of the first pneumatic valve Q, so that the vacuum chuck I can suction the torque converter. Because the first port of the shuttle valve R is connected with the fourth port of the first pneumatic valve Q, when the air signal is output through the fourth port of the first pneumatic valve Q, the air signal is input to the shuttle valve R, so that the shuttle valve R inputs the air signal to the first pneumatic valve Q again, the first pneumatic valve Q can output the air signal to the vacuum generator F, and then the vacuum generator F can always generate negative pressure, so that the vacuum chuck I can always suction the torque converter, at this time the suction button A can be released, and the next operation can be performed.

[0052] When the torque converter is carried, the vacuum generator F generates negative pressure, and then the torque converter is suctioned by the vacuum chuck I. When the vacuum generator F has a fault such as air leakage or air break, the vacuum chuck I cannot maintain the suction state, and the torque converter can suddenly fall to cause a safety accident. Therefore, in one embodiment of the present application, as shown in Figure 1 The system can include a one-way valve H connected between the vacuum generator F and the vacuum chuck I. The air outlet of the one-way valve H can be connected with the vacuum generator F, and the air inlet of the one-way valve H can be connected with the vacuum chuck I. The one-way valve H can maintain the vacuum state for a certain period of time when the vacuum generator F has air leakage or air break, so that the vacuum chuck I can maintain the suction ability for a certain period of time, so as to facilitate the staff to handle the emergency situation and avoid the safety accident caused by the sudden falling of the torque converter.

[0053] In one embodiment of the present application, as shown in Figure 1 The system can further include a vacuum pressure gauge G connected with the vacuum generator F. The negative pressure generated by the vacuum generator F can be displayed by the vacuum pressure gauge G, so as to determine whether the negative pressure generated by the vacuum generator F reaches the standard.

[0054] In one embodiment of the present application, as shown in Figure 2As shown, the system can include handles 1, support 2 and lifting ring 3. The number of handles 1 can be two, and a lifting button E and a common button C can be arranged on one handle 1, and a release button B and a suction button A can be arranged on the other handle. The support 2 can be connected with the two handles 1, and the vacuum chuck I can be arranged at the bottom of the support 2 to pneumatically suck or release the hydraulic torque converter. The lifting ring 3 can be arranged at the top of the support 2. The lifting ring 3 can be lifted by the pneumatic hoist M, and then the support 2 and the vacuum chuck I at the bottom of the support 2 can be lifted and lowered. The number of vacuum chucks I can be three, so that when moving the hydraulic torque converter, three hydraulic torque converters can be lifted at a time to save the time of the staff carrying.

[0055] In an embodiment of the present application, as shown in Figure 3 The system can include fixed stands 4, beam stands 5 and connecting tracks 6. The fixed stands 4 can be arranged on both sides of the assembly line, and the extended ends of the fixed stands 4 can extend to the off-line warehouse. The beam stands 5 can connect the two extended ends of the fixed stands 4 together. One end of the connecting track 6 can be connected with the beam stand 5, and the other end can be connected with the fixed stand 4 on the assembly line, and the pneumatic hoist M can be slidably arranged at the bottom of the connecting track 6. The fixed stands 4 are arranged on both sides of the assembly line, and when it is necessary to carry the hydraulic torque converter from the off-line warehouse to the assembly line, the hydraulic torque converter can be sucked by the vacuum chuck I, then the lifting ring can be lifted by the pneumatic hoist M, and then the hydraulic torque converter and the lifting ring can be lifted, and then the pneumatic hoist M can be moved to the assembly line through the connecting track 6, and then the pneumatic hoist M is lowered again to lower the hydraulic torque converter onto the assembly line, and then the release button B is pressed to move the hydraulic torque converter to the assembly line.

[0056] In an embodiment of the present application, as shown in Figure 4 and Figure 5 The system can further include a guide stand 7 and a guide block 9. The guide stand 7 can be arranged near the edge of the assembly line, and a guide column 8 can be arranged on the guide stand 7. The guide column 8 can be arranged vertically on the guide stand 7. A guide block 9 can be arranged at the top edge of the support 2. Limiting blocks 10 can be arranged at the top and bottom of the guide block 9 to cooperate with the guide column 8. The limiting blocks 10 can cooperate with the guide column 8 to enable the guide block 9 and the support 2 connected with the guide block 9 to move in the vertical direction along the guide column 8, and then the hydraulic torque converter can be vertically lowered onto the assembly line along the guide column 8.

[0057] Through the technical scheme, the vacuum carrying system provided by the application processes compressed air through the air source processing element, the first air control valve, the vacuum generator and the vacuum chuck are connected into an air circuit, so that the vacuum generator can generate negative pressure, and then the vacuum chuck can adsorb the object to be detected. The adsorption button can be connected with the air source processing element and the first air control valve to control the first air control valve to send a gas signal, so that the vacuum generator can generate negative pressure. The first port of the release button can be connected with the first port of the adsorption button to the air source processing element, and the second port can be connected with the first air control valve to control the first air control valve to send a gas signal into the vacuum chuck, so that the vacuum chuck releases the object to be carried. The pneumatic hoist can be connected with the air source processing element to drive the vacuum chuck to move in the vertical direction. The lifting button can be connected with the air source processing element to control the pneumatic hoist to move in the vertical direction. After the pneumatic hoist lifts the torque converter, it can be moved to the designated position. The system can simplify the carrying process of the staff, save manpower, and move the torque converter to the designated position without manual carrying.
