Description

Technical Field

[0001] This utility model relates to a gun barrel anti-pull device for a suspended filling equipment in an automobile assembly line, belonging to the technical field of suspended filling equipment. Background Technology

[0002] Currently, in the passenger vehicle production process, the refueling equipment used in vehicle assembly mainly includes suspended refueling equipment and ground-based refueling equipment, with suspended refueling equipment being more common. Suspended refueling equipment is equipped with a refueling gun and a barrel. The refueling gun is connected to one end of the barrel, and the other end of the barrel is connected to the refueling control mechanism. The end of the refueling gun in the refueling equipment is called the refueling head.

[0003] However, the filling head in existing suspended filling equipment cannot accelerate or decelerate in accordance with the movement of the vehicle, and cannot achieve the fault tolerance of the filling head following the movement of the vehicle, resulting in damage to the vehicle caused by equipment errors. Utility Model Content

[0004] This invention addresses the shortcomings of existing suspension-type refueling equipment's acceleration and deceleration functions that follow vehicle movement by providing a refueling head anti-pull mechanism that can accurately feedback the barrel position.

[0005] The anti-pull mechanism of the filling head of this filling device adopts the following technical solution:

[0006] The anti-pull mechanism includes a fixed bracket, an acceleration trigger, a deceleration trigger, and a detection sensor. The acceleration trigger, deceleration trigger, and detection sensor are all mounted on the fixed bracket, and the acceleration trigger and deceleration trigger are electrically connected to the detection sensor.

[0007] The fixed bracket is provided with a fixed seat for fixing the fixed bracket to the barrel of the refueling equipment. The fixed seat is provided with a barrel locking hole. After locking onto the barrel, the two opening and closing parts are fastened together with screws.

[0008] The acceleration trigger and deceleration trigger are a pair of closures mounted on the same rotating shaft, which is connected to the fixed bracket.

[0009] The detection sensor is a proximity switch.

[0010] The acceleration trigger and deceleration trigger (a pair of closures) on the same rotating shaft can be opened from both the front and rear directions. When either end is opened, it can drive the trigger to rotate along the rotating shaft, thereby disengaging the trigger at that end from the detection sensor. After the detection sensor (proximity switch) is disengaged, the detection signal is disconnected, triggering the detection sensor to provide corresponding signal feedback, thereby accelerating or decelerating the refueling equipment to adjust the positional relationship between the vehicle and the refueling equipment.

[0011] The entire mechanism is fixed to the barrel of the refueling equipment using a mounting bracket, and the refueling gun (refueling head) on the refueling equipment is connected to the vehicle. The refueling equipment and the vehicle are connected through the barrel. The actual state of the trigger activates the detection sensor, which provides feedback on the positional relationship between the refueling equipment and the vehicle. The refueling equipment adjusts its acceleration and deceleration according to the positional relationship, improving the fault tolerance of the refueling equipment in following the movement of the vehicle.

[0012] This utility model relates to the anti-pull function of the nozzle barrel in a suspended filling device on a passenger vehicle assembly line. It enables the suspended filling device to accelerate and decelerate in sync with the vehicle's movement, improving the fault tolerance of the device and preventing nozzle pull-out, thus avoiding damage to the vehicle caused by system errors. This utility model has the following characteristics:

[0013] 1. It adopts a trigger with self-resetting locking force, which can overcome the weight of the filling gun barrel and reduce the influence of the filling gun barrel length.

[0014] 2. It can achieve automatic anti-pull in both forward and backward directions, and realize real-time adjustment of the acceleration or deceleration of the refueling equipment and the vehicle.

[0015] 3. Sensor detection can quickly provide feedback on the anti-pull status and accurately provide feedback on the positional relationship between the refueling equipment and the vehicle. Attached Figure Description

[0018] The components are: 1. fixed base, 2. fixed bracket, 3. acceleration trigger, 4. deceleration trigger, 5. detection sensor, 6. rotating shaft, and 7. barrel chuck.

[0019] For detailed implementation methods, please refer to [link / reference].

[0020] like Figure 1 and Figure 2 As shown, the anti-pull mechanism of the dispensing head of the dispensing equipment of this utility model includes a fixed bracket 2, an acceleration trigger 3, a deceleration trigger 4, and a detection sensor 5. The acceleration trigger 3, the deceleration trigger 4, and the detection sensor 5 are all mounted on the fixed bracket 2, and the acceleration trigger 3 and the deceleration trigger 4 are electrically connected to the detection sensor 5. The fixed bracket 2 is provided with a fixing seat 1 for fixing the fixed bracket 2 to the barrel of the dispensing equipment. The fixing seat 1 is an opening and closing structure with a barrel locking hole 7. After being locked onto the barrel, the two opening and closing parts are fastened together with screws.

[0021] Acceleration trigger 3 and deceleration trigger 4 are mounted on the same rotating shaft 6 (see...) Figure 2 The pair of closures on the sensor 5 can be opened from both the front and rear directions. Once either end (one end of the pair of closures, i.e., the acceleration trigger 3 or the deceleration trigger 4) is opened, it can drive the trigger to rotate along the shaft, thereby disengaging the trigger from the detection sensor 5. The shaft 6 is connected to the fixed bracket 2.

[0022] The detection sensor 5 is a proximity switch. When it is deactivated, the detection signal is disconnected, triggering the detection sensor 5 to provide corresponding signal feedback, causing the refueling equipment to accelerate or decelerate, thereby adjusting the positional relationship between the vehicle and the refueling equipment.

[0023] The working process of the aforementioned institutions is as follows.

[0024] The entire mechanism is secured to the barrel of the refueling device via mounting bracket 1. The refueling gun (refueling head) on the refueling device is then connected to the vehicle, and the refueling device is connected to the vehicle via the barrel.

[0025] As the vehicle moves forward on the conveyor tray or hanger, the refueling equipment follows (controlled by a drive motor). When the conveyor speed exceeds the refueling equipment's following speed, the vehicle moves forward away from the equipment. The nozzle connecting the vehicle and the equipment drags the acceleration trigger 3. Once the acceleration trigger 3 has moved a certain distance, it activates, rotates along the shaft, and disengages from the detection sensor 5, triggering the sensor 5 to send a signal. The sensor 5 then provides corresponding feedback, indicating the positional relationship between the refueling equipment and the vehicle. Based on the feedback information and the equipment's operating status, the refueling equipment issues an acceleration control command, increasing the speed of the drive motor controlling the refueling equipment's following movement. This reduces the positional relationship between the vehicle and the equipment, improving the refueling equipment's tolerance for following the vehicle's movement.

[0026] Conversely, when the vehicle moves forward on the conveyor tray or hanger, if the conveyor speed is less than the following speed of the refueling equipment, the vehicle will move backward away from the refueling equipment. The gun barrel connected between the vehicle and the refueling equipment will drag the deceleration trigger 4. When the deceleration trigger 4 moves a certain distance away, it will activate, rotate along the shaft, and disengage from the detection sensor 5, triggering the detection sensor 5 to send a signal. The detection sensor 5 will provide corresponding signal feedback, indicating the positional relationship between the refueling equipment and the vehicle. Based on the feedback information and the equipment's operating status, the refueling equipment will issue a deceleration control command, reducing the speed of the drive motor that controls the refueling equipment to follow the vehicle's movement, thereby reducing the positional relationship between the vehicle and the refueling equipment and improving the fault tolerance of the refueling equipment in following the vehicle's movement.
