Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and more specifically, to a control mechanism for an anti-drop gripper. Background Technology

[0002] In industrial automation, battery handling is crucial. Typically, automated equipment uses gripper cylinders to pick up and move batteries. In existing operations, when a sensor on the gripper detects the battery directly beneath it, a solenoid valve controls the gripper cylinder to clamp the battery. The entire mechanism then moves, moving the battery to the target location. Once reached, the solenoid valve releases the gripper, releasing the battery. However, this design has significant drawbacks in the event of a power outage or air supply interruption, potentially causing the battery to fall or damaging the equipment, leading to safety risks and economic losses.

[0003] Current gripper designs present two main problems in the event of a power outage: first, if power is interrupted during battery handling, the grippers cannot maintain a clamping position, causing the battery to fall; second, regardless of whether the grippers are handling the battery, they remain clamped in the event of a power outage, which could lead to collisions with other equipment. These problems primarily stem from the fact that existing gripper pneumatic circuit designs do not adequately consider fall prevention mechanisms, or that existing fall prevention mechanisms are ineffective, resulting in battery falls and equipment damage. In industrial production, battery falls can not only damage equipment but also endanger the safety of operators. More seriously, battery falls can trigger major safety accidents such as fires and explosions, leading to incalculable economic losses. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a control mechanism for an anti-drop gripper, which can enable the gripper to maintain clamping force and hold the battery during the battery gripping process, effectively reducing the risk of accidental drop or collision of the mechanism during battery handling.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a control mechanism for an anti-fall gripper, the improvement of which is that it includes a gripper cylinder, a reversing valve, a pneumatic two-way valve, a first three-way valve, a second three-way valve, a third three-way valve and a one-way valve.

[0006] The reversing valve has a first port and a second port, and the pneumatic two-way valve has a pneumatic control port, a third port and a fourth port, and the on / off connection between the third port and the fourth port is controlled by the pneumatic control port;

[0007] The first three-way valve is connected to the first port, the air inlet chamber of the gripper cylinder, and the air control port of the pneumatic two-way valve via pipelines; the second three-way valve is connected to the exhaust chamber of the gripper cylinder, the third port of the pneumatic two-way valve, and one end of the one-way valve; the third three-way valve is connected to the second port, the fourth port of the pneumatic two-way valve, and the other end of the one-way valve, and the one-way valve is unidirectionally open from the third three-way valve to the second three-way valve.

[0008] In the above structure, the reversing valve is a three-position five-way dual-electric control solenoid valve with central leakage. The three-position five-way dual-electric control solenoid valve enables air intake or exhaust at the first port and air exhaust or intake at the second port.

[0010] The cylinder mounting plate is vertically fixed to the back plate, and the lifting cylinder is fixedly installed at the bottom of the cylinder mounting plate; the lifting seat is slidably installed below the cylinder mounting plate, and the cylinder rod of the lifting cylinder is fixedly connected to the lifting seat. The lifting cylinder drives the lifting seat to move up and down below the cylinder mounting plate.

[0011] Multiple gripper cylinders are fixedly installed side by side on the lifting base, and the product is clamped by the pneumatic grippers of the gripper cylinders.

Multiple one-way valves are fixed side by side on the horizontal plate; multiple directional valves are fixed side by side on the back plate; and multiple pneumatic two-way valves are fixed side by side on the side of the cylinder mounting plate.

[0013] In the above structure, a slide rail mounting plate is fixed below the cylinder mounting plate and is arranged in a vertical direction. The slide rail mounting plate is provided with a vertical slide rail.

[0014] A vertical slider is fixed on the lifting seat, and the vertical slider is slidably mounted on the vertical slide rail.

[0015] In the above structure, a rib is fixedly provided at the corner of the slide rail mounting plate and the back plate. A limiting rod is fixed on the rib in the vertical direction. When the lifting seat moves to the upper stop position, the top of the limiting rod hits the lifting seat.

[0016] In the above structure, a junction box is provided on the top of the back plate.

[0017] The beneficial effects of this utility model are: by controlling the opening and closing action of the gripper cylinder by the reversing valve, and with the cooperation of the pneumatic two-way valve and the one-way valve, the air pressure in the exhaust chamber of the gripper cylinder can be maintained during the gripping process.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Reference Figure 1As shown, this utility model discloses a control mechanism for an anti-drop gripper. Specifically, the control mechanism includes a gripper cylinder 10, a reversing valve 20, a pneumatic two-way valve 30, a first three-way valve 401, a second three-way valve 402, a third three-way valve 403, and a one-way valve 50. The reversing valve 20 has a first port 201 and a second port 202. In this embodiment, the reversing valve 20 is a three-position five-way dual-electric control solenoid valve with a central vent. The three-position five-way dual-electric control solenoid valve enables air intake or exhaust at the first port 201 and air exhaust or intake at the second port 202. The three-position five-way dual-electric control solenoid valve can adapt to various working modes and requirements, providing stable and reliable performance in clamping, holding, and releasing operations. Especially in gripper systems, the state of the gripper can be flexibly adjusted according to specific operational needs, improving the system's adaptability and operational efficiency. For example, in... Figure 1 In the illustrated embodiment, the reversing valve 20 is located on the far left, with the first port 201 being the air inlet and the second port 202 being the air outlet. (Continuing to refer to...) Figure 1 As shown, the pneumatically controlled two-way valve 30 has a pneumatically controlled port 301, a third port 302, and a fourth port 303. The pneumatically controlled two-way valve 30 controls the connection between the third port 302 and the fourth port 303 through the pneumatically controlled port 301. In this embodiment, when the pneumatically controlled port 301 has air pressure, the third port 302 and the fourth port 303 can be connected; when the pneumatically controlled port 301 has no air pressure, the third port 302 and the fourth port 303 are closed.

[0025] Furthermore, the first three-way valve 401 is connected to the first port 201, the air inlet chamber 101 of the gripper cylinder 10, and the pneumatic port 301 of the pneumatic two-way valve 30 via pipelines; the second three-way valve 402 is connected to the exhaust chamber 102 of the gripper cylinder 10, the third port 302 of the pneumatic two-way valve 30, and one end of the one-way valve 50; the third three-way valve 403 is connected to the second port 202, the fourth port 303 of the pneumatic two-way valve 30, and the other end of the one-way valve 50, and the one-way valve 50 is unidirectionally open from the third three-way valve 403 to the second three-way valve 402.

[0026] Based on the above structure, we will explain in detail the working principle of the control mechanism for the anti-fall gripper of this utility model. Figure 1In the state shown, this is the process of the gripper releasing: air enters through the first port 201 of the reversing valve 20 and the air intake chamber 101 of the gripper cylinder 10. At the same time, the airflow is diverted through the first three-way valve 401 to the pneumatic port 301 of the pneumatic two-way valve 30, triggering the pneumatic two-way valve 30 to open. This allows the third port 302 and the fourth port 303 of the pneumatic two-way valve 30 to be connected. The pipeline of the second port 202 of the reversing valve 20 can then draw gas from the exhaust chamber 102 on the right side of the gripper cylinder 10 through the pneumatic two-way valve 30. At this time, the gripper is driven to release. At this time, the one-way valve 50 cannot be opened, and the gas in the exhaust chamber 102 can only be discharged through the pneumatic two-way valve 30.

[0027] exist Figure 2 In the illustrated state, the gripper is clamping: The reversing valve 20 is switched to the rightmost position. Exhaust is achieved through the first port 201, and intake is achieved through the second port 202. The airflow enters the exhaust chamber 102 of the gripper cylinder 10 through the one-way valve 50, and the gas in the intake chamber 101 of the gripper cylinder 10 is discharged through the first three-way valve 401 and the first port 201. At this point, the gripper of the gripper cylinder 10 clamps the battery. In this state, because the pneumatic control port 301 of the pneumatic two-way valve 30 is not driven by air pressure, the third port 302 and the fourth port 303 cannot connect, and the pneumatic two-way valve 30 is closed. When the reversing valve 20 is de-energized, because the pneumatic two-way valve 30 is closed, the one-way valve 50 can only allow airflow to flow unidirectionally from the third three-way valve 403 to the second one-way valve 50. Therefore, the air pressure in the exhaust chamber 102 of the gripper cylinder 10 can be maintained, effectively preventing the gripper from loosening.

[0028] In the above embodiment, the reversing valve 20 is used for the opening and closing action of the gripper cylinder 10, and achieves precise control of the gripper of the gripper cylinder 10 by receiving control signals. The one-way valve 50 ensures that the gas can only flow in one direction, prevents gas backflow, and ensures that the gripper cylinder 10 can maintain appropriate pressure when the gas circuit is cut off. The pneumatically controlled two-way valve 30 can automatically switch the gas circuit when the gas circuit is cut off, and the gripper cylinder 10 can safely release the battery. When the sensor detects that the battery is directly under the gripper, the reversing valve 20 receives the signal and the gripper of the gripper cylinder 10 clamps the battery. When the battery moves to the desired position, the reversing valve 20 controls the gripper of the gripper cylinder 10 to release the battery. (Refer to...) Figure 3As shown, the control mechanism for the anti-fall gripper of this utility model further includes a back plate 60, a lifting seat 70, a cylinder mounting plate 80, and a lifting cylinder 90. The back plate 60 is vertical, and a junction box 601 is provided on the top of the back plate 60. The cylinder mounting plate 80 is vertically fixed on the back plate 60, and the lifting cylinder 90 is fixedly installed at the bottom of the cylinder mounting plate 80. The lifting seat 70 is slidably installed below the cylinder mounting plate 80, and the cylinder rod of the lifting cylinder 90 is fixedly connected to the lifting seat 70. The lifting cylinder 90 drives the lifting seat 70 to move up and down below the cylinder mounting plate 80. Multiple gripper cylinders 10 are fixedly installed side by side on the lifting seat 70, and the product is gripped by the pneumatic grippers of the gripper cylinders 10. In this embodiment, there are four reversing valves 20, one-way valves 50, pneumatic two-way valves 30, and gripper cylinders 10.

[0029] Furthermore, the back plate 60 is provided with opposing side plates 602, and a horizontal plate 603 is fixed on the opposing side plates 602. Multiple one-way valves 50 are fixed side-by-side on the horizontal plate 603; multiple directional valves 20 are fixed side-by-side on the back plate 60; and multiple pneumatic two-way valves 30 are fixed side-by-side on the side of the cylinder mounting plate 80. In this embodiment, a vertically oriented slide rail mounting plate 801 is fixed below the cylinder mounting plate 80, and a vertical slide rail (not shown in the figure) is provided on the slide rail mounting plate 801; a vertical slider (not shown in the figure) is fixed on the lifting seat 70, and the vertical slider is slidably mounted on the vertical slide rail. A rib (not shown in the figure) is fixedly provided at the corner of the slide rail mounting plate 801 and the back plate 60. A limiting rod 90 is fixed on the rib and is arranged in the vertical direction. When the lifting seat 70 moves to the upper stop position, the top of the limiting rod 90 is pressed against the lifting seat 70 to limit the lifting seat 70.

[0030] In the above embodiment, multiple directional valves 20 are fixedly mounted on the back plate 60 and arranged side by side. Multiple check valves 50 are fixedly mounted on the horizontal plate 603 and arranged side by side. Multiple pneumatically controlled two-way valves 30 are arranged side by side on the cylinder mounting plate 80, and the multiple check valves 50 are positioned between the directional valves 20 and the pneumatically controlled two-way valves 30. The side-by-side arrangement ensures a neat and smooth air circuit design while saving space and simplifying the wiring of the air and electrical circuits. The side-by-side layout makes the installation and maintenance of each valve more convenient and reduces the complexity of disassembling and replacing components. Positioning the check valves 50 between the directional valves 20 and the pneumatically controlled two-way valves 30 ensures smooth airflow and precise control, optimizes the overall air circuit design, and improves the system's response speed and stability. This layout design effectively prevents gas backflow, ensuring that the gripper cylinder 10 maintains appropriate pressure even in the event of a gas outage. After receiving a signal via the gas reversing valve 20, it controls the gripper cylinder 10 to clamp the battery. Gas enters the pneumatically controlled two-way valve 30 through the one-way valve 50, achieving the clamping operation. The control of the pneumatically controlled two-way valve 30 ensures that the gripper cylinder 10 can safely release the battery, improving the system's safety and reliability. After the gripper cylinder 10 clamps the battery, the drive assembly moves as a whole, transporting the battery to the target position. Upon reaching the target position, the reversing valve 20 controls the gripper cylinder 10 to release the battery, and gas flows smoothly out through the pneumatically controlled two-way valve 30 and the one-way valve 50. In the event of a gas outage or power failure, the pneumatically controlled two-way valve 30 and the one-way valve 50 automatically switch the gas path to ensure that the gripper cylinder 10 can safely release the battery, preventing it from falling.

[0031] The present invention provides a control mechanism for an anti-drop gripper that enables the gripper cylinder 10 to maintain clamping force on the battery only during the battery gripping process, effectively reducing the risk of accidental drop or collision during battery handling and minimizing potential economic losses.

[0032] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
