Description

Technical Field

[0001] This utility model relates to the field of wire harness processing accessory equipment, specifically a wire harness waterproof plug feeding device. Background Technology

[0002] Waterproof plugs are rubber products used to seal the inner cavities of wires and connectors, primarily in automotive engine wiring harnesses to provide waterproofing. Current procedures require the waterproof plugs from the plug box to be fed into a feeding track before installation. There are two main feeding devices: one is a vibratory feeder, which arranges the plugs using vibration, with an arrangement mechanism on the guide rail, reducing subsequent arrangement steps. However, vibratory feeders are bulky, noisy, and vibrate excessively, making them inconvenient to use. Furthermore, vibratory feeders lack versatility, requiring different feeders for different plugs, which is inconvenient. The other method is vacuum suction feeding, which uses a vacuum pump to draw the plugs to a arranging mechanism, arranging them before conveying them via a linear guide rail. This method uses an air separator on the linear guide rail to remove misaligned products, ensuring proper placement. However, arranging the plugs on the linear guide rail affects the overall process, is prone to jamming, requires frequent manual intervention, and is inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide a wire harness waterproof plug feeding device to solve the problem of inconvenience in the use of existing waterproof plug feeding devices. It proposes a new type of positioning mechanism that accurately determines the positive and negative directions of the waterproof plugs by detecting the built-in visual detector of the conduit and drives the rotating disk to rotate so that the output waterproof plugs face the same direction.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire harness waterproof plug feeding device, comprising: a suction mechanism, an arrangement mechanism, and a conveying mechanism. The suction mechanism is connected to the arrangement mechanism and is used to convey the waterproof plug to the top of the arrangement mechanism. The conveying mechanism is connected to the arrangement mechanism and is used to convey the waterproof plug. The arrangement mechanism includes a detection guide tube, a rotating disk, and an output guide tube. The detection guide tube is connected to the suction mechanism, and the output guide tube is connected to the conveying mechanism. The detection guide tube has a built-in vision detector for determining the orientation of the waterproof plug. The rotating disk has a material channel, which includes a temporary storage channel and a direct output channel. The rotating disk is connected to a rotation drive mechanism to drive the rotating disk to rotate.

[0005] As a further improvement to the above technical solution:

[0006] The suction mechanism includes a suction nozzle, a vacuum generator, a diverting pipe, and a discharge pipe. The suction nozzle is located at the lower part of the vacuum generator, and the diverting pipe is located at the upper part of the vacuum generator. The diverting pipe is connected to the detection conduit. The diverting pipe is designed at a 45-degree angle to prevent the waterproof plug from falling out of its original position after suction. A throttle valve is connected to the vacuum generator to adjust the suction volume.

[0007] The steering pipe and the feed pipe are provided with honeycomb-shaped vent holes on their corresponding sides, and the upper end of the steering pipe is provided with a cover, and the cover is provided with an air outlet.

[0008] The direct output channel is arranged along the diameter of the rotating disk, and the two temporary storage channels are symmetrically distributed along the direct output channel.

[0009] The direct output channel and the temporary storage channel are connected, and a blocking switch is provided between the direct output channel and the temporary storage channel to allow the direct output channel and the temporary storage channel to be connected or independent.

[0010] The blocking switch is an electromagnetic induction switch, including a sensing block and an electromagnetic driver. When the visual detector detects that the waterproof plug is in the forward direction, the electromagnetic driver drives the sensing block to move in the forward direction, connecting the direct output channel and the temporary storage channel. The waterproof plug enters the direct output channel through the temporary storage channel and then enters the output conduit. When the waterproof plug is detected to be in the reverse direction, the electromagnetic driver controls the sensing block to move in the reverse direction, making the direct output channel and the temporary storage channel independent, and the waterproof plug enters the temporary storage channel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model's wire harness waterproof plug feeding device uses a built-in visual detector in the detection conduit to accurately determine the orientation of the waterproof plug and whether it is broken. This prevents incorrectly oriented or broken waterproof plugs from entering subsequent processes, effectively preventing wire harness sealing defects caused by waterproof plug issues, reducing the wire harness defect rate, and improving overall product quality.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1As shown, the wire harness waterproof plug feeding device of this embodiment includes: a suction mechanism 1, an arrangement mechanism 2, and a conveying mechanism 3. The suction mechanism 1 is connected to the arrangement mechanism 2 and is used to convey the waterproof plug to the top of the arrangement mechanism 2. The conveying mechanism 3 is connected to the arrangement mechanism 2 and is used to convey the waterproof plug. The arrangement mechanism 2 includes a detection conduit 21, a rotating disk 22, and an output conduit 23. The detection conduit 21 is connected to the suction mechanism 1, and the output conduit 23 is connected to the conveying mechanism 3. The detection conduit 21 has a built-in vision detector for determining the orientation of the waterproof plug. The rotating disk 22 has a material channel, including a temporary storage channel 221 and a direct output channel 222. The rotating disk 22 is connected to a rotation drive mechanism to drive the rotating disk 22 to rotate. The detection conduit 21 is made of transparent material. The vision detector includes an image capture unit for capturing a picture of the waterproof plug and determining the current orientation of the waterproof plug through a connected controller. It can also be used to determine whether the waterproof plug is broken. If it is broken, it will cause sealing defects in the wire harness, leading to an increase in the wire harness defect rate. If a waterproof plug visual inspection is implemented, the lower part of the rotating disk 22 should also be connected to a defective product pipeline to transport the defective products. It should be noted that related support structures are not shown in this application, such as the mounting bracket for the rotating disk 22, the mounting bracket for the inspection conduit 21, and the connection structure between the visual detector and the inspection conduit 21. These are all conventional designs and are not detailed here, nor do they affect the implementation of this application.

[0025] The rotation drive mechanism can drive the rotating disk 22 to rotate. The rotation includes forward rotation, reverse rotation, and rotation at a given angle. A stepper motor is preferably used as the rotation drive mechanism. A protective cover is provided outside the rotating disk 22 to prevent the waterproof plug from falling off. The detection conduit 21 and the output conduit 23 extend into the protective cover to realize the material conveying.

[0026] like Figure 2 and Figure 3 As shown, the suction mechanism 1 is a commonly used vacuum suction mechanism, including a suction nozzle 11, a vacuum generator 12, a diverting pipe 13, and a discharge pipe 14. The suction nozzle 11 is located at the lower part of the vacuum generator 12, and the diverting pipe 13 is located at the upper part of the vacuum generator 12. The diverting pipe 13 is connected to the detection guide pipe 21. A honeycomb-shaped exhaust hole 15 is provided on the corresponding side of the diverting pipe 13 and the discharge pipe 14. A cover 16 is provided at the upper end of the diverting pipe 13, and an air outlet 17 is provided on the cover 16. In use, the vacuum generator 12 is connected to an air pipe to create a negative pressure state, allowing it to suck up materials from below. By adjusting the air pressure, different materials can be sucked up. The vacuum generator 12 uses an SMC vacuum generator air delivery amplifier.

[0027] Example 1

[0028] like Figure 4 and Figure 5As shown, in this embodiment, the direct output channel 222 is arranged along the diameter of the rotating disk 22, and the two temporary storage channels 221 are symmetrically distributed along the direct output channel 222. The arrows in the figure indicate the waterproof plug method; upward arrows indicate the desired direction for outputting the waterproof plug. Figure 4 In the process, the direction of the detection tube 21 for detecting the waterproof plug is downward, which indicates a mismatch in direction. The stepper motor drives the rotating disk 22 to rotate, so that the temporary storage channel 221 is connected to the detection tube 21, allowing the waterproof plug to enter the temporary storage channel 221. Then, the rotating disk 22 rotates, so that the temporary storage channel 221 is connected to the output tube 23, and the waterproof plug is discharged from the output tube 23 in the forward direction. Figure 5 In the middle, the direction of the waterproof plug in the detection conduit 21 is upward with the arrow pointing upward, which is the correct direction. The stepper motor drives the rotating disk 22 to rotate, so that one end of the straight outlet channel 222 is connected to the detection conduit 21, and the other end of the straight outlet channel 222 is connected to the output conduit 23. The waterproof plug is discharged from the output conduit 23 in the positive direction.

[0029] Example 2

[0030] like Figure 6 As shown, in this embodiment, the direct output channel 222 and the temporary storage channel 221 are connected. A blocking switch 223 is provided between the direct output channel 222 and the temporary storage channel 221, allowing the direct output channel 222 and the temporary storage channel 221 to be connected or independent. When the blocking switch 223 is open, the direct output channel 222 and the temporary storage channel 221 are independent; when the blocking switch 223 is closed, the direct output channel 222 and the temporary storage channel 221 are connected.

[0031] The blocking switch 223 is an electromagnetic induction switch, comprising a sensing block and an electromagnetic actuator. When the visual detector detects that the waterproof plug is in the forward direction, the electromagnetic actuator drives the sensing block to move in the reverse direction, connecting the direct output channel 222 and the temporary storage channel 221. The waterproof plug then enters the direct output channel 222 through the temporary storage channel 221 and subsequently enters the output conduit 23. When the waterproof plug is detected to be in the reverse direction, the electromagnetic actuator controls the sensing block to move in the forward direction, making the direct output channel 222 and the temporary storage channel 221 independent, and the waterproof plug enters the temporary storage channel 221. Forward movement means that the blocking switch 223 is open, extending the sensing block into the channel, making the direct output channel 222 and the temporary storage channel 221 independent. Reverse movement means that the blocking switch 223 is closed, the sensing block leaves the channel, and connecting the direct output channel 222 and the temporary storage channel 221.

[0032] Similar to the steps in Example 1, the direction of the detection tube 21 for the waterproof plug is downward, indicating a mismatch in direction. The stepper motor drives the rotating disk 22 to rotate, connecting the temporary storage channel 221 to the detection tube 21. The blocking switch 223 is then opened, causing the waterproof plug to remain in the temporary storage channel 221. The rotating disk 22 is then driven to connect the temporary storage channel 221 to the output tube 23. The direction of the waterproof plug in the detection tube 21 is then upward, and the stepper motor drives the rotating disk 22 to rotate, connecting the direct output channel 222 to the detection tube 21. The blocking switch 223 is then closed, allowing the waterproof plug to enter the output tube 23 from the direct output channel 222.

[0033] When in use, the suction nozzle is placed into the material box, and the waterproof plug is introduced into the material box. By adjusting the air pressure, the waterproof plug can be sucked to the turning pipe 13 and fall into the detection guide tube 21 from the discharge pipe 14. The detection guide tube 21 captures the image through the camera, and the computer recognizes the image to determine the direction of the waterproof plug and controls the motor to move, so that the rotating disk 22 rotates, so that the waterproof plug is discharged in a uniform direction. After being discharged into the conveying mechanism 3, it enters the next process in an orderly manner.

[0034] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
