Description

Technical Field

[0001] This utility model relates to the field of flipping and positioning machine technology, and in particular to a flipping and positioning machine. Background Technology

[0002] A flipping positioner is a device specifically designed for adjusting the position and orientation of workpieces during industrial production. Through mechanical transmission and automated control, it can adjust the workpiece to the required position and orientation, thereby meeting the stringent requirements of assembly, inspection, and other processes. The main structure of the flipping positioner consists of a chassis and a frame. The frame is installed between two chassis and serves to support the workpiece and adjust its position and orientation. Inside the chassis are components such as a motor, controller, and power supply. The motor acts as a power source to drive the frame to rotate according to a preset program, thereby adjusting the position and orientation of the workpiece. The controller is responsible for receiving operating commands and controlling the motor's speed, direction, etc., to ensure that the frame's movement meets the process requirements.

[0003] During the continuous operation of the flipping positioner, the core components inside the chassis, such as the motor, controller, and power supply, are all operating under high load. As these components generate a lot of heat during operation, and the interior of the chassis is usually a relatively enclosed environment, the heat is difficult to dissipate effectively. This may cause the component temperature to rise continuously, leading to overheating failure. Excessive temperature may cause the component to catch fire. Existing chassis designs often lack effective immediate fire extinguishing measures in the face of such sudden fires. Once a fire starts, it may spread rapidly, not only burning the burning component itself, but also further damaging other critical components and internal electrical wiring inside the chassis, resulting in the overall failure of the equipment and even potentially causing more serious safety accidents.

[0004] To address the aforementioned problems, this application proposes a flipping positioner. Utility Model Content

[0005] Based on the technical problems existing in the background art, this utility model proposes a flipping positioner.

[0006] The present invention proposes a flipping and positioning machine, comprising a chassis and a frame;

[0007] The frame is installed between two chassis, and a motor and controller are installed on one inner wall of the chassis, with the motor used to drive the frame to rotate.

[0008] A protective cover is installed inside the chassis via an elastic element. An electromagnet is installed on the inner wall of the other side of the chassis. A magnetic rod that is magnetically connected to the electromagnet is installed on the outer side of the protective cover.

[0009] The protective cover has a fire extinguishing chamber, and a fire extinguishing assembly is installed in the fire extinguishing chamber. The fire extinguishing assembly is filled with inert gas.

[0010] The elastic element has a first position state and a second position state. In the first position state, it is in a retracted posture, and the magnetic rod on the protective cover is magnetically connected to the electromagnet. In the second position state, it is in an extended posture, and the magnetic rod is disconnected from the electromagnet. The protective cover is placed on the motor and the controller.

[0011] Preferably, the elastic element includes a limiting rod and a spring. Two horizontally arranged limiting rods are symmetrically installed inside the chassis, and the protective cover is located between the two limiting rods. Sleeves are installed on both sides of the protective cover. The two sleeves are slidably sleeved on the two limiting rods respectively. A spring is sleeved on the limiting rod, and the two ends of the spring are respectively connected to the sleeve and the inner wall of the other side of the chassis.

[0012] Preferably, the fire extinguishing assembly includes an annular pipe and an air source unit. The annular pipe is installed on the inner wall of the protective cover and located in the fire extinguishing chamber. The annular pipe has multiple circumferentially distributed air jet holes on the side near the motor. The air source unit is connected to the annular pipe.

[0013] Preferably, the gas source unit includes a gas storage cylinder, a gas supply pipe, and a valve. The bottom of the annular pipe is connected to the gas supply pipe, the gas storage cylinder is connected to the bottom end of the gas supply pipe, and inert gas is filled inside the gas storage cylinder. A valve is installed on the gas supply pipe.

[0014] Preferably, a smoke sensor is installed inside the chassis, and the smoke sensor is used to detect smoke.

[0015] Preferably, the motor, smoke sensor, electromagnet, and valve are all electrically connected to the controller.

[0016] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0017] 1. When a fire occurs due to overload operation of components such as motors and controllers inside the chassis, the smoke sensor detects the smoke and then de-energizes the electromagnet. The elastic element then switches from a contracted state to an extended state, causing the protective cover to be placed over the motor and controller, placing them in the fire extinguishing chamber inside the protective cover and separating them from the wiring arranged on the inner wall of the chassis. Subsequently, the gas source in the fire extinguishing component delivers inert gas to the annular pipe, and then sprays the inert gas through the annular pipe to extinguish the fire at the location of the motor and controller. The above design uses the protective cover to separate the burning components from other components and wiring inside the chassis, which can effectively prevent the fire from spreading to other critical components and electrical wiring inside the chassis, thereby avoiding the failure of the overall function of the equipment and causing more serious safety accidents due to the spread of fire, and ensuring the safety of the equipment and the surrounding area.

[0018] 2. The above design uses fire extinguishing components to extinguish the fire on the burning parts, which can extinguish the fire source in time. Furthermore, the inert gas fire extinguishing will not cause secondary damage to components such as motors and controllers. It can minimize the damage to core components caused by fire, reduce equipment maintenance costs, improve equipment reliability and service life, and ensure that the equipment can maintain normal operation or reduce the losses caused by failure as much as possible in the event of a sudden fire.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] like Figure 1-5 As shown, the present invention proposes a flipping and repositioning machine, which includes a housing 1 and a frame 2;

[0027] The frame 2 is installed between two chassis 1. A motor 101 and a controller 102 are installed on one inner wall of the chassis 1, and the motor 101 is used to drive the frame 2 to rotate.

[0028] A protective cover 4 is installed inside the chassis 1 via an elastic element 3. An electromagnet 5 is installed on the inner wall of the other side of the chassis 1. A magnetic rod 41 that is magnetically connected to the electromagnet 5 is installed on the outer side of the protective cover 4.

[0029] The protective cover 4 has a fire extinguishing chamber, and the fire extinguishing chamber is equipped with a fire extinguishing component 6, which is filled with inert gas.

[0030] The elastic element 3 has a first position state and a second position state. In the first position state, it is in a retracted posture, and the magnetic rod 41 on the protective cover 4 is magnetically connected to the electromagnet 5. In the second position state, it is in an unfolded posture, and the magnetic rod 41 is disconnected from the electromagnet 5. The protective cover 4 covers the motor 101 and the controller 102.

[0031] Under normal conditions, the elastic element 3 is in a retracted position, and the protective cover 4 is magnetically connected to the electromagnet 5 on the inner wall of the chassis 1 via the outer magnetic rod 41. At this time, the protective cover 4 does not cover the motor 101 and the controller 102. When a fire occurs inside the chassis 1, the electromagnet 5 is de-energized, and its magnetic connection with the magnetic rod 41 is broken. The elastic element 3 switches from a retracted position to an extended position. Under the force of the elastic element 3, the protective cover 4 moves and covers the motor 101 and the controller 102. At the same time, the fire extinguishing component 6 in the fire extinguishing chamber inside the protective cover 4 can release inert gas to perform fire extinguishing operations. When the motor 101 is running, it drives the frame 2 to rotate under the control of the controller 102, thereby adjusting the position and posture of the workpiece. The above design, through the switching of the two position states of the elastic element 3 and the cooperation of the electromagnet 5 and the magnetic rod 41, can quickly cover the key components with the protective cover 4 in case of an emergency, preventing the spread of fire. The inert gas fire extinguishing of the fire extinguishing component 6 can reduce secondary damage to the components.

[0032] In a specific embodiment, the elastic element 3 includes a limiting rod 31 and a spring 32. Two horizontally arranged limiting rods 31 are symmetrically installed inside the housing 1, and the protective cover 4 is located between the two limiting rods 31. Sleeve blocks 42 are installed on both sides of the protective cover 4. The two sleeve blocks 42 are slidably sleeved on the two limiting rods 31 respectively. The spring 32 is sleeved on the limiting rod 31, and the two ends of the spring 32 are respectively connected to the sleeve block 42 and the inner wall of the other side of the housing 1. Under normal conditions, the spring 32 is in a contracted state. When the electromagnet 5 is de-energized, the spring 32 recovers its deformation and unfolds, pushing the sleeve block 42 to slide along the limiting rod 31, thereby driving the protective cover 4 to move and cover the outside of the motor 101 and the controller 102.

[0033] In a specific embodiment, the fire extinguishing component 6 includes an annular pipe 61 and a gas source 62. The annular pipe 61 is installed on the inner wall of the protective cover 4 and located in the fire extinguishing chamber. The annular pipe 61 has multiple circumferentially distributed jet holes 611 on the side near the motor 101. The gas source 62 is connected to the annular pipe 61. When fire extinguishing is required, the gas source 62 delivers inert gas into the annular pipe 61. The inert gas flows in the annular pipe 61 and is evenly sprayed out through the multiple circumferentially distributed jet holes 611, covering the area where the motor 101 and the controller 102 are located, and extinguishing the fire source in time.

[0034] In a specific embodiment, the gas source unit 62 includes a gas storage cylinder 621, a gas supply pipe 622, and a valve 623. The bottom of the annular pipe 61 is connected to the gas supply pipe 622, and the gas storage cylinder 621 is connected to the bottom end of the gas supply pipe 622. Inert gas is filled inside the gas storage cylinder 621, and the valve 623 is installed on the gas supply pipe 622. Under normal conditions, the valve 623 is in the closed state, and the inert gas is stored in the gas storage cylinder 621. When a fire extinguishing command is triggered, the valve 623 opens, and the inert gas in the gas storage cylinder 621 enters the annular pipe 61 through the gas supply pipe 622 and is then sprayed out through the jet hole 611.

[0035] It should be noted that inert gases include, but are not limited to, nitrogen and carbon dioxide.

[0036] In a specific embodiment, a smoke sensor 103 is installed inside the chassis 1, and the smoke sensor 103 is used to sense smoke. When the motor 101, controller 102 and other components inside the chassis 1 catch fire and produce smoke, the smoke sensor 103 senses the smoke signal and transmits the signal to the relevant control unit.

[0037] In a specific embodiment, the motor 101, smoke sensor 103, electromagnet 5, and valve 623 are all electrically connected to the controller 102. After the smoke sensor 103 detects a smoke signal, it sends the signal to the controller 102. The controller 102 receives the signal, analyzes and processes it, and then issues a command to de-energize the electromagnet 5, causing the protective cover 4 to move its covering component, and to open the valve 623 to release inert gas for fire extinguishing. At the same time, the controller can also stop the motor 101 from running as needed to prevent the fault from escalating.

[0038] In a specific embodiment, a door panel is hinged to the back of the chassis 1, which can be used by staff to perform routine maintenance on the inside of the chassis 1, and can also be used to replace relevant components after a fire. This is existing technology and will not be elaborated further.

[0039] The specific working principle of this positioner is as follows:

[0040] Under normal conditions, the spring 32 in the elastic element 3 is in a contracted state, and the protective cover 4 is magnetically connected to the electromagnet 5 on the inner wall of the housing 1 through the magnetic rod 41. At this time, the protective cover 4 does not cover the motor 101 and the controller 102. The valve 623 in the air source section 62 is closed, and the gas storage cylinder 621 stores inert gas. The smoke sensor 103 continuously monitors the environment inside the housing 1. Under the control of the controller 102, the motor 101 can drive the frame 2 installed between the two housings 1 to rotate, thereby adjusting the position and posture of the workpiece to meet the production process requirements.

[0041] When components such as the motor 101 and controller 102 inside the chassis 1 catch fire due to overload operation, the generated smoke is detected by the smoke sensor 103. The smoke sensor 103 transmits the smoke signal to the controller 102. After receiving the signal, the controller 102 immediately issues a series of commands. First, it controls the electromagnet 5 to be de-energized, disconnecting the magnetic connection between the electromagnet 5 and the magnetic rod 41. The spring 32 of the elastic element 3 returns to its original deformation, switching from a contracted state to an extended state, pushing the sleeve block 42 to slide along the limit rod 31, thereby moving the protective cover 4, which finally covers the motor 101 and controller 102. On step 02, the burning component is separated from other components and wiring in the chassis 1. Then, the controller 102 controls the valve 623 to open, and the inert gas in the gas storage cylinder 621 enters the annular pipe 61 through the gas supply pipe 622. Then, it is evenly sprayed out through multiple circumferentially distributed jet holes 611 on the annular pipe 61 to extinguish the fire in the area where the motor 101 and the controller 102 are located. At the same time, the controller 102 can control the motor 101 to stop running to prevent the fault from spreading further. After the fire is extinguished, the components can be reset through relevant operations so that the equipment can be used normally in the future.

[0042] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model, and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
