Description

Technical Field

[0001] This utility model relates to the field of automatic joint assembly technology, and in particular to an automatic shell feeding device. Background Technology

[0002] Fast charging (QC) connectors are crucial automotive components, coming in various types and used in large quantities. Currently, they are primarily manufactured using injection molding. A typical QC connector is assembled from components such as a housing, sealing ring, retaining ring, and locking clip. Among these, housing assembly, as the first step in assembly, directly impacts the efficiency of the entire production process.

[0003] Because QC connectors often have irregular structures (e.g., wider at the top and narrower at the bottom), they need to be aligned to a uniform direction during the feeding process to improve assembly efficiency. Currently, commonly used feeding mechanisms rely on vibratory feeders coupled with customized material channels to arrange materials neatly before conveying them to the workstation. However, such mechanisms have limited applicability, mainly suitable for products with regular shapes. They are difficult to use for QC connector housings with irregular structures, making stable and consistent directional feeding challenging. Utility Model Content

Detailed Implementation

[0048] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0049] like Figures 1-8As shown, this utility model provides an automatic shell feeding device, which is suitable for automatic feeding of materials, the material being the shell of a QC connector, which has an irregular structure with a large diameter at the top and a small diameter at the bottom.

[0050] This utility model includes an installation platform 001, on which a storage bin 100 is provided, and a conveyor belt assembly 200 and a shaking assembly 300 are provided inside the storage bin 100.

[0051] The storage silo 100 is used to store materials and is shaped like a W-shaped bucket at the bottom. The W-shaped design at the bottom of the storage silo 100 divides it into two independent feeding zones 101. Materials fed into the storage silo 100 through the top opening fall into the two feeding zones 101 respectively. Each feeding zone 101 is equipped with a conveyor belt assembly 200 for conveying materials outwards. The conveyor belt assemblies 200 in the two feeding zones 101 are symmetrically designed, and their structure and working principle are completely identical. To avoid redundancy, the following detailed description uses the conveyor belt assembly 200 in one feeding zone 101 as an example; the conveyor belt assembly 200 in the other feeding zone can be applied by analogy.

[0052] To install the conveyor belt assembly 200, a long, obliquely arranged clearance opening is provided on each of the two obliquely inclined sides of the storage bin 100 (i.e., on the two obliquely inclined sides of the two feeding areas); to install the moving feeding assembly 300, two obliquely arranged bottom plates 102 at the bottom of the storage bin 100 are provided with two long, obliquely arranged opening slots 1021 along their length, and the two opening slots 1021 on each bottom plate 102 are arranged side by side at intervals.

[0053] Each conveyor belt assembly 200 includes a conveyor belt 201, a first rotary drive motor 202, a drive roller 203, and a synchronous belt 204; wherein, the conveyor belt 201 is the prior art, which includes a rotating shaft at both ends and a belt wrapped around the rotating shaft at both ends, and a plurality of partition plates 2011 are spaced apart on the outer circumferential surface of the belt.

[0054] The conveyor belt 201 is fixed to the clearance opening along its length. The bottom of the conveyor belt 201 blocks the bottom of the feeding area 101 to prevent material leakage; the top of the conveyor belt 201 and the top of the clearance opening are left with an appropriate distance, and the two together form the discharge port 103.

[0055] Preferably, each discharge port 103 is covered with a sheet metal cover 106 with an R-angle.

[0056] To securely support the conveyor belt 201, a connecting seat 205 is provided on each side of the clearance opening on the mounting platform 001. The two ends of the shaft at the bottom of the conveyor belt 201 are rotatably connected to the corresponding connecting seat 205. This installation method ensures that one working surface of the conveyor belt 201 is inside the feeding area 101, while the other side is outside. The body of the first rotary drive motor 202 is fixedly mounted on the mounting platform 001, and its drive output end is connected to the drive roller 203. A synchronous belt 204 is wrapped around the drive roller 203 and the shaft at the bottom of the conveyor belt 201, thereby transmitting power to the conveyor belt 201.

[0057] In order to ensure that the material in each feeding zone 101 falls effectively onto the partition plate 2011 on the conveyor belt 201 and rises with the conveyor belt 201 to the discharge port 103 for discharge, a shaking component 300 is installed between the two feeding zones 101.

[0058] The material shaking assembly 300 includes a lifting cylinder 301, two sets of movable plates 302, a connecting rod assembly 303, and two fixed plates 304. In this invention, a total of four movable plates are provided. Each movable plate 302 has a fan-shaped structure, with its narrow side defined as the top and its long, curved side as the bottom. Every two movable plates form a group, movably connected to two opening slots on the bottom plate 102. The connecting rod assembly 303 includes a rectangular frame 3031, with a connecting rod 3032 rotatably connected to each of its four corners.

[0059] Each fixed plate 304 is fixed to the outside of each bin bottom plate 102. The body of the lifting cylinder 301 is fixed on the mounting platform 001 and located below the adjacent areas of the two loading areas 101. Its drive output end is fixed to the middle part of the frame 3031 with its drive output end facing upward. At this time, the frame 3031 is located between the two fixed plates 304. The middle to bottom part of each movable plate 302 is movably engaged in an opening slot 1021 of each bin bottom plate 102. The upper part of each movable plate 302 is located outside each opening slot 1021 and is rotatably connected to the fixed plate 304. The other end of each connecting rod 3032 is connected to the middle part of the corresponding movable plate 302.

[0060] When the lifting cylinder 301 is activated, its drive output end drives the connecting rod assembly 303 to move up and down, thereby driving each movable plate 302 to move up and down along the opening groove 1021. This movement can effectively loosen the material accumulated at the bottom of each feeding area, thus ensuring that the material can effectively fall onto its partition plate 2011 during the conveyor belt 201's continuous conveying process from bottom to top.

[0061] Preferably, the storage silo 100 is located at the top side of the silo between the two feeding ports 103, and a door panel 104 is hinged to it. A scraper plate 105 is fixed to each of the two inner ends of the door panel 104 along its length. When the door panel 104 is open, it provides a convenient feeding inlet for the storage silo 100; when the door panel 104 is closed, the two scraper plates 105 correspond to one side of the conveyor belt 201 located at the discharge port 103, and can scrape excess material on the conveyor belt 201 back into the corresponding feeding area 101, thereby preventing discharge port blockage or uneven material accumulation, and ensuring the stability and continuity of the conveying process.

[0062] On the mounting platform 001, and below each discharge port 103, there is a material transfer mechanism 400. Each material transfer mechanism 400 includes a transfer belt 401 and a second rotary drive motor 402 that drives the transfer belt 401 to run linearly.

[0063] To maintain a suitable height difference between the conveyor belt 401 and the discharge port 103 and prevent material damage from falling, the conveyor belt 401 is mounted on the support frame 002. The second rotary drive motor 402 is mounted on the support frame 002 and located below the conveyor belt 401. Its drive output end is connected to the shaft of the conveyor belt 401 via a drive wheel, thereby driving the conveyor belt 401 to run in a straight line. The end of each conveyor belt 401 located below the discharge port 103 is defined as the material inlet, and the opposite end is defined as the material outlet.

[0064] To prevent material spillage, each conveyor belt 401 has a belt baffle 403 fixedly attached to each of its two sides along its length; to facilitate the smooth flow of material out of the transfer outlet, each transfer outlet is provided with a discharge plate 404. The discharge plate 404 consists of an inclined base plate and side plates respectively connected to both sides of the base plate. The two side plates are fixedly attached to the corresponding belt baffle 403, so that the base plate of the discharge plate 404 is close to the transfer outlet, thus playing a guiding role.

[0065] Furthermore, when the material on the transfer belt 401 does not need to be transported to the subsequent vibration orientation mechanism, a recycling box 500 is fixedly connected to the outside of the material transfer inlet of each transfer belt 401 to facilitate the automatic recycling of the material on the transfer belt 401.

[0066] The top of the recycling box 500 is open, and the upper end of the side facing the transfer inlet has a notch that is connected to the transfer inlet.

[0067] Each material transfer inlet is hinged to a return material baffle 405 via a hinge joint. When the return material baffle 405 is in the closed state, it blocks the notch of the recycling box 500; when it is in the open state, the notch is connected to the material transfer inlet.

[0068] The upper end of the return material baffle 405 is hinged to the upper ends of the two belt baffles 403 at the material transfer inlet by a hinge on each side. The upper end of the return material baffle 405 is also provided with a push plate 4051 on each side. The lower end of the return material baffle 405 is provided with a first magnetic suction member 4061, and the lower ends of the two belt baffles 403 at the material transfer inlet are respectively provided with a second magnetic suction member 4062. The first magnetic suction member 4061 and the second magnetic suction member 4062 can attract each other.

[0069] Each of the two belt baffles 403 at the material transfer inlet is also provided with a linear drive cylinder 407 on its outer side, with its drive output end facing the push plate 4051.

[0070] During normal conveying, the transfer belt 401 runs in the forward direction. When the material is transported to the vibration orientation mechanism, the return baffle 405 is kept closed by the attraction between the first magnetic suction member 4061 and the corresponding second magnetic suction member 4062, blocking the material inlet to prevent material from falling.

[0071] Residual material recycling: The second rotary drive motor 402 drives the conveyor belt 401 to run in reverse. When transporting material to the recycling box, the linear drive cylinder 407 extends its drive output end towards the push plate 4051, pushing the push plate on the return baffle 405. This causes the first magnetic suction member 4061 and the second magnetic suction member 4062 to separate, and the return baffle 405 flips upward to open, connecting the notch of the recycling box with the material transfer inlet. The material then falls into the recycling box along with the reverse-running conveyor belt 401.

[0072] Preferably, each conveyor belt 401 has a material monitoring port 4031 staggered between its two belt baffles 403, and each material monitoring port is provided with a mounting plate 4032. Each mounting plate 4032 is provided with a through-beam photoelectric sensor (not shown) for detecting whether there is material on the conveyor belt 401. Two through-beam photoelectric sensors 408 are also provided on opposite sides of the material transfer outlet of the conveyor belt 401.

[0073] Furthermore, to adjust the installation position of the through-beam photodetector, each mounting plate 4032 has an arc-shaped opening.

[0074] Preferably, each linear drive cylinder 407 has a locking block 4071 connected to its drive output end. The locking block 4071 has a locking interface on its top surface facing the push plate 4051, and locking holes are provided on both sides of the locking interface, parallel to the horizontal plane, with the two locking holes facing each other. Correspondingly, each push plate 4051 also has a locking hole on its front end facing the locking block 4071. When material recycling is not required, the front end of each push plate 4051 is locked into the locking interface of the locking block 4071. At this time, the three locking holes are coaxially arranged. By inserting a bolt through these three locking holes, the return baffle 405 can be further tightened to prevent it from being accidentally opened. When material recycling is required, the bolt in the locking hole can be removed.

[0075] On the mounting platform 001, and below each material transfer outlet, there is a vibration orientation mechanism 600 for orienting and arranging materials.

[0076] Each vibration orientation mechanism 600 includes a vibrator 601 and a vibratory plate 602 mounted on the vibrator 601. An appropriate drop distance is provided between the vibratory plate 602 and the material transfer outlet to ensure that the material can fall smoothly and start the vibration sorting process.

[0077] On each vibrating plate 602, several elongated directional grooves 603 are spaced apart and parallel along its length. The width of each directional groove 603 is slightly larger than the diameter of the lower end of the material to allow the lower end of the material to be inserted, and its width is smaller than the diameter of the upper end of the material to prevent the upper end of the material from falling in, thereby realizing the orientation screening of the material.

[0078] In addition, the inner wall of the top surface of each directional groove 603 is also machined with an annular inclined surface 6031. This inclined surface structure can effectively guide the lower end of the material to slide more smoothly into the directional groove 603.

[0079] When the material falls from the transfer outlet onto the vibratory plate 602, the vibrator 601 drives the vibratory plate 602 and the material on it to vibrate. During this process, the material adjusts its posture due to the vibration. Because the material has an irregular shape with a larger diameter at the top and a smaller diameter at the bottom, under continuous vibration, the smaller end is more likely to get stuck in the orientation groove 603 due to size matching, while the larger end is blocked outside the orientation groove 603 due to its larger size. After a period of vibration, all the material is adjusted to a uniform vertical posture, with the lower end (smaller end) facing down and located in the orientation groove, and the upper end (larger end) facing up and located outside the orientation groove. At this point, the material has completed its orientation and is ready for the subsequent gripping process.

[0080] Preferably, each vibratory plate 602 is detachably installed in a fence frame 604 by bolts. The fence frame 604 has four side guards that surround the vibratory plate 602 to prevent material from falling during vibration.

[0081] To further improve changeover efficiency and quickly adapt to materials of different sizes, the four corners of the enclosure frame 604 are detachably connected to the vibrator 601 via a quick-release elbow clamp 605 and a positioning pin 606.

[0082] Specifically, a positioning plate 607 is fixedly connected to each of the four corners of the fence frame 604, and each positioning plate 607 has a positioning hole that matches the positioning pin on the vibrator 601. A positioning pin 606 is installed at each of the four corners of the top surface of the vibrator 601, and the fixed end of the quick elbow clamp 605 is fixed to the top surface of the vibrator 601 and located on one side of the corresponding positioning pin 606.

[0083] When installing the vibratory feeder 602 and the fence frame 604, first, use the positioning holes and corresponding positioning pins on the positioning plates 607 at the four corners of the fence frame 604 to achieve initial fixation. Then, press down on the quick-release elbow clamp 605 so that its clamping ends abut and press against the corresponding positioning plates 607. Under the clamping action of the quick-release elbow clamp 605, the vibratory feeder 602 and the fence frame 604 form a stable and detachable connection with the vibrator 601.

[0084] In addition, a visual inspection mechanism 700 is provided on the mounting platform and above each vibratory plate 602. The visual inspection mechanism 700 is used to detect the position of the material on the vibratory plate 602. The visual inspection mechanism 700 of this utility model is a CCD camera module.

[0085] On the mounting platform, and on one side of each vibratory plate 602, there is also a robotic arm 800 for grasping materials, which accurately grasps the materials according to the position of the materials provided by the vision inspection mechanism 700.

[0086] The above description is only a preferred embodiment of the present utility model and is not intended to limit 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 technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
