Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing technology, and in particular to a swing-type contact positioning mechanism for automated pipe fitting feeding. Background Technology

[0002] Electric vehicle frames are welded from numerous tubular components. To improve processing efficiency, automated tubular feeding is necessary during component manufacturing. Current automated tubular feeding systems first randomly pile the components in a hopper. Inside the hopper are multi-stage lifting platforms with inclined surfaces. As the platforms rise and fall, they transport the components upwards in stages, eventually placing them on a conveyor belt with the length of the components aligned with the belt's length. The components then move with the conveyor belt to a loading station, where cylinders push them into a storage bin. To ensure the cylinders only push the components after they are in position, contact sensors are used to detect their placement. However, because the ends of the components are hollow, changes in diameter can cause them to miss the sensor probes, making the automated feeding system unsuitable for components of different diameters. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a swing-type contact positioning mechanism for automated feeding of pipe fittings, so that pipe fittings of different diameters can be stably triggered by the contact sensor.

[0004] Technical Solution: To achieve the above objectives, the present invention provides a swing-type contact positioning mechanism for automated pipe loading, comprising a conveyor belt with a loading station on the conveyor belt. A pipe-pushing mechanism and a loading storage bin are respectively arranged on both sides of the loading station. When the pipe-pushing mechanism operates, it can push the pipe at the loading station into the loading storage bin. A contact sensor is provided at the loading station, and the contact sensor is electrically connected to the pipe-pushing mechanism. A swing element is provided on the side of the contact sensor facing the input direction of the conveyor belt. When the pipe moves with the conveyor belt to the loading station, it pushes the swing element to swing until it touches the probe of the contact sensor, thereby triggering the operation of the pipe-pushing mechanism.

[0005] Furthermore, the upper end of the swing member is hinged to the support frame, the lower end of the swing member can swing back and forth in the length direction of the conveyor belt, and the bottom of the swing member is separated from the conveyor belt by a gap; when the swing member hangs down naturally under the action of gravity, it separates from the contact sensor.

[0006] Furthermore, the swinging component is a plate, with one side of the plate facing the contact sensor.

[0007] Furthermore, the swinging component is composed of an upper plate and a lower plate that are hinged together. The lower plate can swing relative to the upper plate, so that the lower plate can make surface contact with the probe of the contact sensor after the angle is adjusted.

[0008] Furthermore, a damping element is also provided on the support frame, and the side plate of the swing member facing away from the contact sensor is opposite to the damping element.

[0009] Furthermore, the damping element is a buffer pad, and the hinged portion of the upper plate and the lower plate is opposite to the buffer pad, so that the buffer pad can buffer the upper plate and the lower plate.

[0010] Furthermore, the tube pushing mechanism includes a telescopic cylinder. When the swinging member swings to touch the contact sensor, the telescopic cylinder extends to push the tube at the loading station into the loading storage bin.

[0011] Furthermore, the material storage bin includes a material storage ramp, with limiting plates on both sides of the material storage ramp. The distance between the limiting plates on both sides is consistent with the length of the pipe, so that the pipe can be arranged on the material storage ramp. There is a material loading switch at the bottom of the material storage ramp, which can block or release the pipe at the bottom of the material storage ramp.

[0012] Beneficial effects: The swing-type contact positioning mechanism for automated pipe feeding of this utility model is equipped with a swing component at the feeding station of the conveyor belt. As the pipe moves closer to the contact sensor with the conveyor belt, it will push the swing component to swing until it touches the probe of the contact sensor. In this way, pipes of different diameters can stably touch the contact sensor, thereby accurately determining whether the pipe is in place, and then triggering the pipe pushing mechanism to push the pipe into the feeding storage bin.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] As attached Figures 1 to 3The aforementioned oscillating contact positioning mechanism for automated pipe fitting feeding includes a conveyor belt 1. During the pipe fitting feeding process, the scattered pipe fittings 4 are first organized by a pipe fitting 4 sorting device, and then the sorted pipe fittings 4 are arranged one by one on the conveyor belt 1. In one embodiment, the pipe fitting 4 sorting device includes a material box containing multiple lifting platforms. The platform surface of the lifting platform is inclined. During the reciprocating lifting process of the lifting platform, the scattered pipe fittings 4 will move upward with the lifting platform step by step, and finally move onto the conveyor belt 1. Then, the shape of the pipe fittings 4 on the conveyor belt 1 is restricted by a limiting mechanism to ensure that only pipe fittings 4 whose length direction is consistent with the length direction of the conveyor belt 1 can stay on the conveyor belt 1. Thus, the pipe fittings 4 are arranged one by one on the conveyor belt 1 and move forward with the conveyor belt 1.

[0018] There is a loading station on conveyor belt 1, as shown in the attached document. Figure 3 As shown, a tube-pushing mechanism 2 and a feeding storage bin 3 are respectively provided on both sides of the feeding station. When the tube-pushing mechanism 2 is activated, it can push the pipe 4 at the feeding station into the feeding storage bin 3.

[0019] As attached Figure 1 As shown, a contact sensor 5 is also installed at the loading station. The contact sensor 5 is electrically connected to the tube pushing mechanism 2. When the contact sensor 5 is touched, it can trigger the tube pushing mechanism 2 to push the tube. A swinging component 6 is installed on the side of the contact sensor 5 facing the input direction of the conveyor belt 1. When the tube 4 moves to the loading station with the conveyor belt 1, the tube 4 will push the swinging component 6 to swing until the swinging component 6 touches the probe of the contact sensor 5, thereby triggering the tube pushing mechanism 2 to move.

[0020] Since one end of the pipe 4 is hollow and the probe of the contact sensor 5 is small, if the diameter of the pipe 4 changes, the pipe 4 may not be able to hit the probe of the contact sensor 5 when it moves forward with the conveyor belt 1, causing the feeding device to be unable to adapt to pipes 4 with different diameters. However, in this utility model, since a swinging member 6 is added, the pipe 4 can indirectly hit the probe of the contact sensor 5 through the swinging member 6.

[0021] A platform is provided on one side of the conveyor belt 1, and a support frame 7 is provided on the platform. The upper end of the swing member 6 is hinged to the support frame 7, and the lower end of the swing member 6 can swing back and forth along the length of the conveyor belt 1. The bottom of the swing member 6 is spaced apart from the conveyor belt 1, so that the swing member 6 will not contact the conveyor belt 1, and also ensures that the pipe 4 moving forward with the conveyor belt 1 can touch the swing member 6. (See attached...) Figure 1 As shown, when the swinging member 6 hangs down naturally under the action of gravity, it separates from the contact sensor 5. At this time, the swinging member 6 will not touch the probe of the contact sensor 5.

[0022] Specifically, the swinging member 6 is a plate, and one side of the plate of the swinging member 6 is opposite to the contact sensor 5, so that the pipe 4 can impact the contact sensor 5 through the plate.

[0023] As attached Figure 1 and 2 As shown, the swinging component 6 is composed of an upper plate 8 and a lower plate 9 connected by hinges. The upper end of the upper plate 8 is hinged to the support frame 7, and the upper end of the lower plate 9 is hinged to the upper plate 8. The swinging direction of both the upper plate 8 and the lower plate 9 is consistent with the length direction of the conveying mechanism. (See attached diagram) Figure 2 As shown, because the lower plate 9 can swing relative to the upper plate 8, it allows the lower plate 9 to make surface contact with the probe of the contact sensor 5 after the angle is adjusted. For pipe fittings 4 of different diameters, one end of the pipe fitting 4 must be tightly attached to the lower plate 9, and one side of the lower plate 9 must be tightly attached to the probe of the contact sensor 5 in order to trigger the contact sensor 5. Therefore, when the contact sensor 5 is triggered, the position of one end of the pipe fitting 4 is fixed, which allows for better positioning of the pipe fitting 4.

[0024] The support frame 7 is also equipped with a damping component. The side plate of the swing member 6 facing away from the contact sensor 5 is opposite to the damping component. When the swing member 6 swings, it will hit the damping component, reducing the energy of the swing member 6, so that the swing member 6 will not hit the contact sensor 5 when it swings back, thus avoiding accidental contact.

[0025] Specifically, the damping element is a buffer pad 10, and the hinged parts of the upper plate 8 and the lower plate 9 are opposite to the buffer pad 10, so that the buffer pad 10 can buffer the upper plate 8 and the lower plate 9, resulting in a better buffering effect.

[0026] As attached Figure 3 As shown, the tube pushing mechanism 2 includes a telescopic cylinder. When the swing member 6 swings to touch the contact sensor 5, the telescopic cylinder extends to push the tube 4 at the loading station to the loading storage bin 3. The loading storage bin 3 includes a storage ramp 11 with limit plates on both sides. The distance between the limit plates is the same as the length of the tube 4, allowing the tube 4 to be arranged on the storage ramp 11. A loading switch 12 is located at the bottom of the storage ramp 11, which can block or release the tube 4 at the bottom of the storage ramp 11. In one embodiment, the discharge end of the loading switch 12 is equipped with a chamfering mechanism, allowing the loading switch 12 to release the tube 4 one by one, with the chamfering mechanism performing chamfering on the tube 4.

[0027] The working principle of this utility model is as follows: the pipe fitting 4 moves forward with the conveyor belt 1. When the pipe fitting 4 moves to the loading station, as shown in the attached... Figure 2As shown, the pipe fitting 4 pushes the lower plate 9 and the upper plate 8 to swing, causing the lower plate 9 to hit the contact sensor 5. The contact sensor 5 then sends an electrical signal, causing the telescopic cylinder to extend and push the pipe fitting 4 into the loading storage bin 3. Then, the lower plate 9 and the upper plate 8 swing under the action of gravity and hit the buffer pad 10, so that the lower plate 9 will not hit the contact sensor 5 when it swings back, thus avoiding accidental activation.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
