Description

Technical Field

[0001] This application relates to the field of material feeding and testing, and in particular to a dual-disc feeding device for wire harness terminal processing. Background Technology

[0002] In the field of wire harness assembly, with the rapid development of technology and the continuous upgrading of various electronic devices, the demand for wire harness assemblies is increasing. As an indispensable connecting component in electronic devices, the assembly quality and efficiency of wire harness assemblies directly affect the performance and production cycle of the equipment. High-quality and efficient wire harness assembly can improve the stability and reliability of equipment, reduce maintenance costs, and is of great significance for electronic equipment manufacturers to gain an advantage in market competition. At the same time, with the trend of equipment miniaturization and integration, higher requirements are placed on the assembly technology of wire harness assemblies, requiring more precise and efficient assembly methods to meet production needs. In the past, to solve the problem of wire harness terminal feeding, the industry mainly adopted the following conventional methods. The most common method is to use a vibratory feeder for terminal feeding, which uses the vibration of the vibratory feeder to arrange the terminals in an orderly manner. Some assembly devices use two vibratory feeders and use conveyor belts or guide rails to transport the terminals from the storage area to the assembly station for processing. Vibratory feeders can achieve orderly arrangement and transportation of terminals to a certain extent, and conveyor belts and guide rails can ensure the delivery of terminals to the assembly station. However, existing feeding methods have significant drawbacks in practical applications. In the assembly of wire harness assemblies, there are various terminal types. When it is necessary to change the wire harness model, it is usually necessary to replace the entire feeding vibratory feeder and conveying mechanism with the corresponding vibratory feeder and conveying mechanism. The replacement process is complicated and requires equipment shutdown, disassembly, installation and debugging, which seriously affects production efficiency. In addition, frequent replacement of vibratory feeders will increase labor and time costs. Utility Model Content

[0003] In order to be applicable to different types of terminals, increase the versatility of the feeding device, avoid the need for frequent replacement of vibratory feeders, and eliminate the need for a series of operations such as stopping, disassembling, installing and debugging the equipment, thereby improving feeding efficiency, this application provides a dual-disc feeding device for wire harness terminal processing.

[0004] A dual-tray feeding device for wire harness terminal processing includes a frame and a feeding mechanism, a photographic monitoring mechanism, and a clamping mechanism disposed on the frame. The feeding mechanism includes two feeding components, each comprising a tray and a feeding element. The feeding element conveys terminals to the tray. The photographic monitoring mechanism is used to detect the flatness of the terminals in the two trays and the accuracy of the clamping mechanism in holding the terminals in real time. The clamping mechanism includes a robotic arm and a positioning clamping component. The robotic arm includes two rotatable clamping heads, and the positioning clamping component is used to clamp the terminals. The two clamping heads clamp two terminals respectively for conveying. By adopting the above technical solution, this dual-tray feeding device for wire harness terminal processing has two feeding components. The feeding element of each feeding component can convey terminals to the tray. This dual-tray design eliminates the need to replace the entire feeding vibratory feeder and conveying mechanism when changing the wire harness model, as is done in traditional methods. This reduces downtime, disassembly, installation, and debugging operations, improves the versatility of the feeding device, and reduces labor and time costs. The photo-monitoring mechanism can detect the flatness of the terminals in the two trays in real time to facilitate gripping by the clamping mechanism, and determine the accuracy of terminal gripping by the clamping mechanism to determine whether a terminal is being gripped correctly. Real-time monitoring can promptly detect unevenness of the terminals and inaccurate gripping issues, preventing defective products due to incorrect terminal gripping posture from entering subsequent processing stages and ensuring processing quality. The robotic arm of the clamping mechanism has two rotatable gripping heads, and the positioning gripping components are used to grip the terminals. The two gripping heads grip two terminals respectively for transfer, achieving simultaneous transfer of two terminals, improving the speed and efficiency of feeding, and further enhancing overall production efficiency. Preferably, each of the feeding components includes a storage cylinder and a guide rail. The storage cylinder includes a rotating wheel assembly and a cylinder body. A storage cavity for storing terminals is formed inside the cylinder. The cylinder body is rotatably mounted on the frame via the rotating wheel assembly. The discharge end of the cylinder body is provided with a discharge port. The feed end of the guide rail extends through the discharge port into the storage cavity. The discharge end of the guide rail is connected to the material tray. When the cylinder body rotates, the terminals rotate with the cylinder body until they fall into the feed end of the guide rail. By adopting the above technical solution, a storage cavity is formed inside the cylinder body for storing terminals, and the cylinder body is rotatably mounted on the frame via the rotating wheel assembly. When the cylinder body rotates, the terminals will rotate with the cylinder body. Because the feed end of the guide rail extends through the discharge port into the storage cavity, and the discharge end of the guide rail is connected to the material tray, as the cylinder rotates, the terminals gradually move to the feed end of the guide rail and fall into it, and are then conveyed to the material tray via the guide rail. This achieves orderly transfer of terminals from the storage cylinder to the material tray, avoiding the problems of reduced production efficiency and increased costs due to equipment changes in traditional feeding methods, and improving the efficiency and stability of feeding. Preferably, a number of levers are spaced apart on the inner wall of the cylinder, and the levers form an angle with the inner wall of the cylinder.By adopting the above technical solution, several levers are spaced apart on the inner wall of the cylinder, forming an angle with the inner wall. When the cylinder rotates, the levers rotate with the cylinder. Due to the angle between the levers and the inner wall of the cylinder, during rotation, the levers can contact the terminals inside the cylinder and apply a certain force to them. This force will push the terminals to move inside the cylinder, making it easier for terminals that might otherwise be piled up or arranged randomly to fall into the guide rail feed end, thereby improving the conveying efficiency of terminals from the storage cylinder to the guide rail. Preferably, the levers are arc-shaped. By adopting the above technical solution, the arc-shaped levers can drive the terminals to rotate more smoothly, which is conducive to the terminals falling into the guide rail feed end better, improving the conveying efficiency of terminals from the storage cylinder to the guide rail. Preferably, the guide rail is inclined towards the tray, and the storage cylinder is inclined towards the guide rail. By adopting the above technical solution, the guide rail is inclined towards the tray, which allows the terminals to move more smoothly from the guide rail to the tray under the action of gravity, reducing the situation where terminals stay or get stuck on the guide rail. Meanwhile, the storage cylinder is inclined towards the guide rail, which facilitates the terminals inside the storage cylinder falling more smoothly into the feed end of the guide rail under the action of gravity and their own rolling, improving the conveying efficiency of terminals from the storage cylinder to the guide rail, and thus improving the overall feeding efficiency of the feeding device. Preferably, the feeding assembly also includes a first vibrating element, which is fixed to the bottom of the tray. By adopting the above technical solution, fixing the first vibrating element to the bottom of the tray causes it to vibrate. This vibration is transmitted to the tray, allowing the terminals in the tray to be arranged more orderly under the action of vibration, avoiding the terminals from stacking or being placed randomly, ensuring that the terminals are placed flat with one side facing upwards, thereby ensuring the smoothness of the clamping process and improving the feeding efficiency. Preferably, the feeding assembly also includes a second vibrating element, which is fixed to the bottom of the guide rail. By adopting the above technical solution, fixing the second vibrating element to the bottom of the guide rail allows the terminals in the guide rail to move more smoothly to the tray through vibration, avoiding the terminal jamming phenomenon, ensuring the stability of terminal conveying, and improving the feeding efficiency. Preferably, the photo-monitoring mechanism includes a first camera, a second camera, an image processor, and a controller. The first camera is positioned downwards above the material tray, and the second camera is positioned upwards on one side of the material tray. The image processor is electrically connected to the first camera and the second camera via signal lines, and the controller is electrically connected to the robotic arm and the first vibrating element via control lines.By adopting the above technical solution, the photo-monitoring mechanism includes a first camera facing downwards above the material tray, a second camera facing upwards to one side of the material tray, an image processor, and a controller. The first camera can detect the flatness of the terminals in the two material trays in real time, and the second camera can detect the accuracy of the clamping mechanism in clamping the terminals in real time. The image processor processes the images captured by the first and second cameras to provide a basis for the controller to control the robot arm and the first vibrating component, ensuring the accuracy and stability of the feeding process, thereby improving the quality of wire harness terminal processing. The two rotatable clamping heads of the robot arm of the clamping mechanism clamp two terminals respectively for transmission, and combined with the positioning clamping assembly to clamp the terminals, achieve efficient terminal transmission. Preferably, the positioning clamping assembly includes a clamping drive and two clamping fingers, with a positioning groove matching the outer contour of the terminal formed between the two clamping fingers. The clamping drive drives the two clamping fingers to clamp the terminal. By adopting the above technical solution, a positioning groove matching the outer contour of the terminal is formed between the two gripping fingers of the positioning clamping assembly. The positioning clamping assembly is used to temporarily store a terminal. When the terminal needs to be clamped, the clamping drive drives the two gripping fingers to move. Since the positioning groove matches the outer contour of the terminal, the terminal can be accurately positioned, ensuring that the terminal is accurately positioned when clamped, avoiding deviations in subsequent processing due to inaccurate clamping position, thereby improving the accuracy and stability of terminal processing. Preferably, a clearance groove for avoiding the clamping head is provided between the two gripping fingers, and the clearance groove is connected to the positioning groove. By adopting the above technical solution, the clearance groove between the two gripping fingers of the positioning clamping assembly, which is connected to the positioning groove, is used to avoid the clamping head, allowing the clamping head to accurately clamp the terminal from the positioning groove, ensuring the accuracy of clamping.

[0005] In summary, this application includes at least one of the following beneficial technical effects:

[0006] 1. With the cooperation of the dual-disc feeding mechanism, the photo monitoring mechanism and the clamping mechanism, when it is necessary to change the wire harness model, the terminals in the two storage cylinders of the feeding mechanism can be directly replaced with the required terminal model. This avoids the complicated operation of replacing the entire feeding vibratory plate and conveying mechanism in the existing feeding method. There is no need to stop the equipment, disassemble, install and debug it, thereby improving production efficiency and reducing labor and time costs.

[0007] 2. The photo monitoring mechanism includes a first camera, a second camera, an image processor, and a controller. The first camera is positioned downwards above the material tray, and the second camera is positioned upwards on one side of the material tray. The image processor is electrically connected to the first and second cameras via signal lines, respectively, and can acquire image information of the terminals in the material tray in real time. This allows for the detection of the flatness of the terminals in the two material trays and the accuracy of the clamping mechanism in holding the terminals, ensuring smooth delivery of the terminals.

[0012] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0013] This application provides a dual-reel feeding device for wire harness terminal processing, referring to... Figure 1 It includes a frame 1 and a feeding mechanism 2, a photo monitoring mechanism 3 and a clamping mechanism 4 installed on the frame 1. The feeding mechanism 2, the photo monitoring mechanism 3 and the clamping mechanism 4 are all installed on the frame 1. This layout facilitates the coordinated work of the various mechanisms.

[0014] The feeding mechanism 2 is responsible for conveying the terminals to the designated position, providing the material base for subsequent processing steps; the photo monitoring mechanism 3 is used to detect the terminal condition in real time, enabling timely monitoring of terminal flatness and the accuracy of terminal clamping by the clamping mechanism 4, so as to make adjustments; the clamping mechanism 4 is used to accurately clamp and transfer the terminals, accurately transferring the terminals conveyed by the feeding mechanism 2 to the processing station. Through the coordinated cooperation of these mechanisms, the overall efficiency and accuracy of wire harness terminal feeding are improved.

[0015] Reference Figure 2Specifically, the feeding mechanism 2 in this embodiment includes two feeding components arranged side-by-side on the frame 1. Each feeding component includes a tray 21 and a feeding element 22, which transfers the terminals to the tray 21. Both feeding elements 22 include a storage cylinder 221 and a guide rail 222. The storage cylinder 221 includes a cylinder body 221a and a rotating wheel assembly 221b. The cylinder body 221a is typically made of metal and is a cylindrical shape with one open end. Its interior forms a storage cavity 221c for storing terminals. The open end of the cylinder body 221a is the inlet end, and the bottom of the cylinder body 221a is the outlet end with an outlet port. The inlet end of the guide rail 222 extends through the outlet port into the storage cavity 221c, and the outlet end of the guide rail 222 communicates with the tray 21. In this embodiment, the inlet end of the cylinder body 221a is provided with a guide plate to guide the terminals into the storage cavity 221c.

[0016] The cylinder 221a is rotatably mounted on the frame 1 via a rotating wheel assembly 221b, which consists of rollers. The cylinder 221a rotates by contacting the rollers. Specifically, the rollers are mounted on the frame 1 via a base to allow space for their rotation. A motor is mounted on one side of the base, passing through the side wall of the base and connecting to the rollers to drive their rotation. The surface of the rollers is typically smoothed to reduce friction with the cylinder 221a, allowing it to rotate more smoothly. As the cylinder 221a rotates, the terminals follow it, falling into the feed end of the guide rail 222. The guide rail 222 is typically made of smooth metal to reduce frictional resistance during the transport process. The guide rail 222 is inclined towards the material tray 21, and the storage cylinder 221 is inclined towards the guide rail 222. This inclination facilitates the smooth descent of the terminals under their own weight. The tilt angle needs to be adjusted reasonably based on factors such as the weight and shape of the terminal, as well as the materials of the guide rail 222 and the storage cylinder 221. A tilt angle between 15° and 45° is more suitable.

[0017] In this embodiment, the inner wall of the cylinder 221a is provided with a plurality of levers 221a1 at intervals. The levers 221a1 form an angle with the inner wall of the cylinder 221a, and the levers 221a1 have an arc-shaped structure. When the cylinder 221a rotates, the levers 221a1 rotate with the cylinder 221a. The arc-shaped levers 221a1 can better push the terminals to rotate, making it easier for the terminals to fall into the feed end of the guide rail 222. The setting of the levers 221a1 can increase the randomness of the movement of the terminals within the cylinder 221a, avoid the terminals from piling up together, and increase the probability of the terminals falling into the guide rail 222.

[0018] Specifically, the feeding assembly also includes a first vibrator 23 and a second vibrator 24. The first vibrator 23 is fixed to the bottom of the tray 21, and the second vibrator 24 is fixed to the bottom of the guide rail 222. The first vibrator 23 and the second vibrator 24 can be small vibrating motors, which use vibration to better arrange and move the terminals in the tray 21 and the guide rail 222. When the tray 21 vibrates, the terminals bounce on the tray 21, avoiding accumulation and ensuring that the terminals are placed in the tray 21 with their faces upwards for easier clamping. If none of the terminals in the tray 21 are facing upwards, the first vibrator 23 can be controlled to vibrate the tray 21 to obtain flat terminals with their faces upwards. When the guide rail 222 vibrates, it can prevent the terminals from blocking in the guide rail 222, allowing the terminals to be fed to the tray 21 more smoothly. This is because vibration can break the friction and accumulation forces between the terminals, allowing the terminals to roll or slide within the guide rail 222. When the tray 21 vibrates, the terminals in the tray 21 are arranged more neatly, facilitating subsequent clamping. Vibration can cause the terminals in the tray 21 to automatically adjust their positions under the action of gravity and vibration, and finally arrange them into a relatively neat state.

[0019] The feeding mechanism 2 achieves orderly delivery of terminals through a combination of a storage cylinder 221, a guide rail 222, a tray 21, and a vibrating element. The storage cylinder 221 stores terminals and transports them to the guide rail 222 by rotation. The guide rail 222 uses tilting and vibration to transfer the terminals to the tray 21. The tray 21, under vibration, aligns the terminals neatly, preparing them for subsequent processing. Specifically, the rotation of the storage cylinder 221 provides the initial power for the terminals to enter the guide rail 222; the tilting and vibration of the guide rail 222 ensure smooth delivery of the terminals within it; and the vibration of the tray 21 further optimizes the arrangement of the terminals, providing conditions for accurate clamping by the clamping mechanism 4.

[0020] Specifically, the image monitoring mechanism 3 in this embodiment includes a first camera 31, a second camera 32, an image processor 33, and a controller 34. The first camera 31 is positioned downwards above the material tray 21, and the second camera 32 is positioned upwards on one side of the material tray 21. The first camera 31 can capture top images of the terminals inside the material tray 21, and the second camera 32 can capture side images of the terminals inside the material tray 21. The image processor 33 is electrically connected to the first camera 31 and the second camera 32 via signal lines. It can analyze and process the images captured by the cameras to determine the flatness of the terminals and the accuracy of the clamping mechanism 4 in clamping the terminals. For example, the image processor 33 can use image processing algorithms to perform edge detection, feature extraction, and other operations on the captured images to determine whether the terminals are flat and whether the clamping mechanism 4 accurately clamps the terminals. The controller 34 is electrically connected to the robotic arm 41 and the first vibrating element 23 via control lines. When the image processor 33 analyzes that the terminal is uneven or the clamping is inaccurate, the controller 34 can control the robotic arm 41 to adjust the clamping action or control the first vibrating element 23 to increase the vibration amplitude to adjust the position of the terminal. The first camera 31 and the second camera 32 of the photo-monitoring mechanism 3 are both 3D cameras. 3D cameras can obtain more comprehensive terminal information and improve the accuracy of monitoring. 3D cameras can obtain three-dimensional information of the terminal through technologies such as laser scanning and structured light, thereby more accurately judging the flatness and clamping accuracy of the terminal. The specific structure and working principle of the image processor 33 and the controller 34 in the photo-monitoring mechanism 3 are conventional and will not be described in detail here.

[0021] Reference Figure 3 Specifically, the clamping mechanism 4 in this embodiment includes a robotic arm 41 and a positioning clamping assembly 42. The robotic arm 41 includes two rotatable clamping heads 411, and the positioning clamping assembly 42 is used to clamp terminals. The two clamping heads 411 clamp two terminals respectively for transfer. The positioning clamping assembly 42 includes a clamping drive 421 and two clamping fingers 422. A positioning groove 423 matching the outer contour of the terminal is formed between the two clamping fingers 422. The clamping drive 421 drives the two clamping fingers 422 to clamp the terminal. The clamping drive 421 can be a cylinder, which drives the clamping fingers 422 to close or open through a telescopic action. When the clamping drive 421 extends, the two clamping fingers 422 close, clamping the terminal in the positioning groove 423; when the clamping drive 421 retracts, the two clamping fingers 422 open, releasing the terminal.

[0022] Specifically, a clearance groove 424 is provided between the two gripping fingers 422 to avoid the gripping head 411. The clearance groove 424 is connected to the positioning groove 423. In this way, when the gripping head 411 approaches the terminal in the positioning groove 423, the clearance groove 424 can prevent interference between the gripping fingers 422 and the gripping head 411. The terminal in this embodiment is made of plastic. In other embodiments, for terminals made of special materials, the positioning and gripping assembly 42 can also use electromagnetic adsorption to grip the terminal. Electromagnetic adsorption can provide a more stable gripping force. The electromagnetic adsorption method generates a magnetic field by energizing, which attracts the terminal into the positioning groove 423. When the power is turned off, the magnetic field disappears, and the terminal is released. The robotic arm 41 is a conventional technology, and its specific structure and working principle will not be described in detail here.

[0023] The working principle and specific process flow steps of this device are as follows:

[0024] 1. Material preparation: Place the terminal into the cylinder 221a of the storage cylinder 221, start the equipment, rotate the wheel set 221b to drive the cylinder 221a to rotate, and at the same time the first vibrator 23 and the second vibrator 24 start to work.

[0025] 2. Terminal conveying: The lever 221a1 on the inner wall of the cylinder 221a rotates with the cylinder 221a, pushing the terminal and causing it to fall into the feed end of the guide rail 222. The guide rail 222 is inclined and, under the action of the second vibrating element 24, the terminal slides smoothly down to the material tray 21 by its own weight and vibration. The first vibrating element 23 makes the terminals in the material tray 21 more neatly arranged.

[0026] 3. Image Monitoring: The first camera 31 and the second camera 32 capture top and bottom images of the terminals in the tray 21, respectively. The image processor 33 analyzes and processes the captured images to determine the flatness of the terminals and the accuracy of the subsequent clamping mechanism 4 in clamping the terminals. If a problem is found, the controller 34 controls the robot arm 41 to adjust the clamping action or controls the first vibrating element 23 to increase the vibration amplitude to adjust the position of the terminals.

[0027] 4. Terminal Clamping and Transfer: The clamping drive 421 of the positioning clamping assembly 42 drives the two clamping fingers 422 to close, clamping the terminals arranged in the tray 21 into the positioning groove 423. The two rotatable clamping heads 411 of the robot arm 41 approach the positioning clamping assembly 42, avoiding interference through the avoidance groove 424. The robot arm 41 first clamps one terminal in the tray 21. After the second camera 32 confirms its qualification, it is temporarily stored in the positioning clamping assembly 42. Then, the robot arm 41 clamps a terminal in another tray 21 and confirms its qualification through the second camera 32. After confirmation, the other clamping head 411 of the robot arm 41 clamps the terminal in the positioning clamping assembly 42 again. The robot arm 41 simultaneously clamps two terminals and transfers them to the processing station.

[0028] The implementation principle of this embodiment is as follows: The frame 1 is equipped with a feeding mechanism 2, a photo monitoring mechanism 3, and a clamping mechanism 4, which work together to improve the feeding efficiency and accuracy. The feeding mechanism 2 has two feeding components, each including a material tray 21 and a feeding component 22 consisting of a storage cylinder 221 and a guide rail 222. The cylinder body 221a of the storage cylinder 221 rotates by a rotating wheel assembly 221b. The inner wall of the cylinder body 221a has an arc-shaped lever 221a1. The guide rail 222 and the storage cylinder 221 are inclined. The feeding component also has a first vibrator 23 and a second vibrator 24, which are fixed to the bottom of the material tray 21 and the guide rail 222, respectively. Vibration causes the terminals to be transported to the material tray 21 in an orderly manner and arranged neatly. The photo monitoring mechanism 3 has a first camera 31, a second 3D camera 32, an image processor 33, and a controller 34, which can detect the flatness of the terminals and the clamping accuracy in real time, and make adjustments if there are any problems. The clamping mechanism 4 has a robotic arm 41 and a positioning clamping component 42. Its working principle is as follows: First, the material is prepared by placing the terminals into the cylinder 221a and starting the equipment to make the cylinder 221a rotate and the vibrating component work; then the terminals are conveyed by the pusher 221a1 pushing the terminals through the guide rail 222 to the material tray 21, and the vibration makes the terminals neatly arranged; then the camera captures the image, the image processor 33 analyzes it, and if there is a problem, the controller 34 adjusts it; finally, the terminals are clamped and conveyed by the positioning clamping component 42 clamping the terminals, and the robot arm 41 clamps two terminals at the same time and conveys them to the processing station after confirming that they are qualified by the photo monitoring.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
