Description

Technical Field

[0001] This utility model belongs to the field of ceramic insert processing technology, and specifically refers to a feeding device with automatic direction adjustment. Background Technology

[0002] Ceramic ferrules are the most commonly used and numerous precision positioning components in fiber optic communication networks. After being formed, ceramic ferrules require post-processing, such as having a chamfer on the outer edge of one end and a tapered hole at the center hole of the other end. Since a large number of ceramic ferrules need to be installed in the tooling in the same direction during subsequent grinding, the head and tail directions of the ceramic ferrules must be identified, adjusted, and arranged before processing.

[0003] Chinese invention patent publication (publication number CN113387147A, publication date 2021.09.14) discloses a ceramic ferrule fiber optic identification precision vibratory feeder, including a vibratory feeder mounting plate, a second fiber optic identification mechanism, and a third fiber optic identification mechanism. A vibratory base is mounted on the top outer wall of the vibratory feeder mounting plate, and a vibratory material tray is mounted on the top outer wall of the vibratory base. A feeding track is mounted on the top of the inner circumference of the vibratory material tray. The second fiber optic identification mechanism includes a first fixing frame fixed to one end of the top outer wall of the vibratory material tray, and a first fixing ring is mounted on the top outer wall of the first fixing frame. A first circular column is slidably connected to the inner wall of the first fixing ring. A circular groove is opened on the top outer wall of the first circular column, and a second optical fiber is slidably connected to the inner wall of the circular groove. A second optical fiber focusing lens is mounted on the bottom outer wall of the second optical fiber. An air blowing microhole is opened on the outer wall of one end of the vibratory material tray. The position of the ceramic product can be identified by the first fiber optic condenser under the first fiber and the second fiber optic condenser under the second fiber. The position of the chamfer at the front end of the ferrule is identified by the light spot to control the operation of the air blowing solenoid valve. As a result, the air pump is turned on and blows the ceramic product to change its position through the air blowing micro-hole, so that it can reach a qualified position, thereby achieving the purpose of automatic position adjustment of the ceramic product.

[0004] The above-mentioned air blowing adjustment method is susceptible to air pressure fluctuations, dust blockage, and product surface differences, resulting in unstable control accuracy, reduced reliability, and frequent maintenance. Summary of the Invention

[0005] The purpose of this invention is to provide a feeding device that can automatically adjust its direction for precise orientation.

[0006] This utility model is implemented as follows: An automatically oriented feeding device includes a vibratory feeder, a mounting plate, and a first driving component. A feeding block and a discharging block are disposed on one side of the mounting plate. The outlet of the vibratory feeder is connected to the feeding block via a feeding pipe. A sliding block is disposed between the feeding block and the discharging block. A guide hole is vertically disposed inside the feeding block. A first insert hole is vertically disposed inside the sliding block. A rotating shaft is rotatably disposed inside the discharging block, and a second insert hole is radially disposed on the rotating shaft. The first driving component drives the sliding block to reciprocate, selectively aligning the first insert hole with either the guide hole or the second insert hole on the same axis. Above the discharge block is a push-out drive assembly that pushes the ceramic insert from the first insert hole into the second insert hole. The rotating shaft is driven to rotate by a second drive component. A blowing channel is arranged laterally inside the discharge block. The blowing channel communicates with the second insert hole when the rotating shaft rotates to the second insert hole. A discharge pipe is connected to the outlet end of the blowing channel, and a blowing pipe is connected to the inlet end of the blowing channel. A sensor for detecting the direction of the ceramic insert is also installed inside the discharge block. The controller controls the direction of the second drive component according to the direction of the ceramic insert detected by the sensor, so that the ceramic insert is adjusted to a uniform direction before being blown out.

[0007] In the aforementioned automatic direction-adjusting feeding device, the top material drive assembly includes a top material cylinder and a top material rod. The top material cylinder includes a piston rod and a drive rod connected to the outer end of the piston rod via a connector. The drive rod and the piston rod are coaxially arranged. The top material rod is movably disposed within the top material mounting seat. The upper end of the top material rod is connected to the drive rod of the top material cylinder via an adapter. The top material rod is driven by the top material cylinder to move downward so that its lower end extends out of the top material mounting seat and pushes the ceramic insert from the first insert hole into the second insert hole.

[0008] In the above-mentioned automatic direction-adjusting feeding device, a spring is sleeved on the drive rod between the connector and the adapter, and the two ends of the spring are respectively pressed against the connector and the adapter.

[0009] In the above-mentioned automatic direction-adjusting feeding device, the top material mounting seat is fixed on the mounting plate by the mounting base, and a first limiting rod is provided on the mounting base. When the adapter moves downward, the first limiting rod abuts against the limiting rod to limit the downward stroke of the piston rod.

[0010] In the above-mentioned automatic direction-adjusting feeding device, the first driving member has a first telescopic rod, and the sliding block is connected to the first telescopic rod.

[0011] In the above-mentioned automatic direction-adjusting feeding device, a guide block is fixed on the mounting plate, and a guide hole is provided on the guide block, through which the first telescopic rod passes.

[0012] In the above-mentioned automatic direction-adjusting feeding device, a fixed seat is also provided on the mounting plate on one side of the discharge block, and a second limiting rod is provided on the fixed seat.

[0013] In the aforementioned automatic direction-adjusting feeding device, the second limiting rod has a threaded section, and the second limiting rod is screwed to the mounting base through the threaded section.

[0014] In the above-mentioned automatic direction-adjusting feeding device, the sensor is a displacement sensor or an optical contrast sensor.

[0015] In the above-mentioned automatic direction-adjusting feeding device, the second driving component is a motor, which is fixed on the other side of the mounting plate, and the rotating shaft passes through the mounting plate.

[0016] The outstanding advantages of this utility model compared to the prior art are: This invention achieves automatic, continuous, and efficient conveying of ceramic ferrules through the ingenious combination of a vibratory feeder, a feeding block, a sliding block, and a discharging block. Its core advantage lies in the automatic adjustment of the ceramic ferrule's orientation via a rotatable shaft and a second ferrule hole design, combined with a top-loading drive assembly. Sensors intelligently detect the ceramic ferrule's orientation, and a second drive component controls the shaft to rotate to a predetermined angle. Finally, a high-pressure airflow precisely blows the oriented ceramic ferrule to the next station, achieving fully automated closed-loop control of orientation adjustment, detection, and output.

[0019] The present invention will be further described below with reference to specific embodiments. See also: Figure 1-3 : This utility model provides an automatic direction-adjusting feeding device, which includes a vibratory feeder 1, a mounting plate 2, and a first driving member 3, wherein the height of the vibratory feeder 1 is higher than that of the mounting plate 2. A feeding block 4 and a discharging block 5 are provided on one side of the mounting plate 2. The outlet of the vibratory feeder 1 is connected to the feeding block 4 via a feeding pipe 6. A sliding block 7 is provided between the feeding block 4 and the discharging block 5. A guide hole is vertically provided inside the feeding block 4, and a first insert hole 8 is vertically provided inside the sliding block 7. A rotating shaft 9 is rotatably provided inside the discharging block 5, and a second insert hole is radially provided on the rotating shaft 9. The first driving member 3 drives the sliding block 7 to reciprocate, so that the first insert hole 8 is selectively coaxially aligned with either the guide hole or the second insert hole. A device is provided above the discharging block 5 to push a ceramic insert 10 from the first insert hole 8 into the second insert hole. The top material drive assembly includes a rotating shaft 9 driven by a second drive component. A horizontal air blowing channel is provided in the discharge block 5. The air blowing channel communicates with the second insert hole when the rotating shaft 9 rotates to the horizontal position. A discharge pipe 11 is connected to the outlet end of the air blowing channel, and an air blowing pipe 12 is connected to the inlet end of the air blowing channel. A sensor for detecting the direction of the ceramic insert 10 is also provided in the discharge block 5. The controller controls the direction of the second drive component according to the direction of the ceramic insert 10 detected by the sensor, so that the ceramic insert 10 is adjusted to a uniform direction before being blown out. The air blowing pipe 12 is connected to an air source, and a solenoid valve for controlling the opening and closing of the air path is provided between the air source and the air blowing pipe 12.

[0020] The working principle of this utility model is as follows: The randomly oriented ceramic inserts 10 are initially sorted by the vibratory feeder 1 and then slid into the guide hole of the feed block 4 via the feed pipe 6. The inner diameter of the feed pipe 6 matches the outer diameter of the ceramic insert 10, and only one ceramic insert 10 is fed at a time. The first drive unit 3 drives the sliding block 7 to move until the first insert hole 8 is vertically aligned with the guide hole of the feed block 4 (i.e., coaxially arranged), and one ceramic insert 10 enters the first insert hole 8 from the guide hole by gravity. The first drive unit 3 drives the sliding block 7 to move until the first insert hole 8 is directly above the rotating shaft 9 on the discharge block 5, and vertically aligned with the second insert hole on the rotating shaft 9. The ejector drive assembly pushes the ceramic insert 10 from the first insert hole 9 into the second insert hole of the rotating shaft 9. At this time, the sensor detects whether the ceramic insert is oriented correctly. If the chamfered end faces upward and the tapered end faces downward, the second drive unit drives the rotating shaft 9 to rotate 90° clockwise, connecting the second insert hole with the air blowing channel. The air blowing pipe 12 then blows air, propelling the ceramic insert 10 in the second insert hole to the next station via the discharge pipe 11. If the chamfered end faces downward and the tapered end faces upward, the second drive unit drives the rotating shaft 9 to rotate 90° counterclockwise, and the air blowing pipe 12 then blows it to the next station. The inner diameter of the air blowing pipe 12 also matches the outer diameter of the ceramic insert 10, conveying only one ceramic insert 10 at a time. Before being blown out, the ceramic insert 10 is adjusted to the direction of being blown out with the chamfered end.

[0021] The second driving component is a motor, which is fixed on the other side of the mounting plate 2, and the rotating shaft 9 passes through the mounting plate 2.

[0022] This invention achieves automatic, continuous, and efficient conveying of ceramic inserts 10 through the ingenious cooperation of a vibratory feeder 1, a feeding block 4, a sliding block 7, and a discharging block 5. Its core advantage lies in the automatic adjustment of the orientation of the ceramic inserts 10 via a rotatable shaft 9 and a second insert hole design, combined with a top-loading drive assembly. Sensors intelligently detect the orientation of the ceramic inserts 10, and a second drive component controls the shaft 9 to rotate to a predetermined angle. Finally, a high-pressure airflow precisely blows the oriented ceramic inserts 10 to the next station, achieving fully automated closed-loop control of orientation adjustment, detection, and output. This structure significantly improves the feeding efficiency and orientation accuracy of the ceramic inserts 10, making it suitable for large-scale automated production.

[0023] Furthermore, the top-feeding drive assembly of this utility model includes a top-feeding cylinder 13 and a top-feeding rod 14. The top-feeding cylinder 13 includes a piston rod 15 and a drive rod 17 connected to the outer end of the piston rod 15 via a connector 16. The drive rod 17 is coaxially arranged with the piston rod 15. The top-feeding rod 14 is movably disposed within the top-feeding mounting base 18. The upper end of the top-feeding rod 14 is connected to the drive rod 17 of the top-feeding cylinder 13 via an adapter 19. The top-feeding rod 14 is driven downward by the top-feeding cylinder 13, causing its lower end to extend out of the top-feeding mounting base 18 and push the ceramic insert 10 from the first insert hole 8 into the second insert hole. The connector 16 can be a nut.

[0024] To provide cushioning and avoid damage to the parts, a spring 20 is sleeved on the drive rod 17 between the connector 16 and the adapter 19 of this utility model, with the two ends of the spring 20 respectively pressing against the connector 16 and the adapter 19.

[0025] It should be noted that the top material mounting seat 15 is fixed to the mounting plate 2 by the mounting base 21. A first limiting rod 22 is provided on the mounting base 21. When the adapter 19 moves downward, the first limiting rod 22 abuts against the piston rod 15 to limit its downward stroke. Specifically, the mounting base 21 is L-shaped, with its horizontal part fixed to the mounting plate 2 by screws and its vertical part fixedly connected to the top material mounting seat 15 by screws. The two L-shaped sides of the mounting base 21 are arranged in the vertical direction. The first limiting rod 22 is fixed on the upper L-shaped side of the mounting base 21, and the connection method can be screwed or welded.

[0026] The first limiting rod 22 provides a rigid and reliable mechanical limit for the downward stroke of the piston rod 15 of the ejector cylinder 13, precisely controlling the downward depth of the ejector rod 14 to ensure that it precisely pushes the ceramic insert 10 into the second insert hole, while effectively preventing excessive downward pressure due to excessive cylinder stroke or control system malfunction. This not only avoids mechanical damage to precision components such as the ejector rod 14, the ceramic insert 10, and the lower rotating shaft 9, but also ensures the consistency and reliability of each ejection action, greatly improving the safety and stability of the entire device.

[0027] In this embodiment, the first driving member 3 has a first telescopic rod, and the sliding block 7 is connected to the first telescopic rod.

[0028] In order to make the sliding block 7 slide smoothly, a guide block 23 is fixed on the mounting plate 2, and a guide hole is provided on the guide block 23, through which the first telescopic rod passes.

[0029] To ensure that the first insert hole 8 and the second insert hole are collinear, this invention also provides a fixing seat 24 on the mounting plate 2 on one side of the discharge block 5. A second limiting rod 25 is provided on the fixing seat 24. When the sliding block 7 moves to abut against the second limiting rod 25, the first insert hole 8 and the second insert hole are collinear. This rigid positioning method effectively eliminates positioning deviations caused by transmission mechanism clearance, inertia, or control errors, fundamentally ensuring the accuracy and reliability of the ejection action and avoiding problems such as ejection failure, impact or damage to the ceramic insert 10 due to hole misalignment.

[0030] Specifically, the second limiting rod 25 has a threaded section, and the second limiting rod 25 is screwed to the fixed seat 24 through the threaded section, which facilitates the adjustment of the top position.

[0031] It should be noted that the sensor is a displacement sensor or an optical contrast sensor. Detection principle: The height difference between the plane of the orifice (one distance value) and the inclined plane of the tapered orifice (another, further distance value) is measured. The presence of this specific height difference confirms the tapered orifice. If the end with the tapered orifice is facing downwards, the displacement sensor can detect the height difference between the center and the bottom surface, confirming that the end with the tapered orifice is facing downwards. If the end with the chamfer is facing downwards, there is no height difference between the center and the bottom surface, confirming that the end with the chamfer is facing downwards.

[0032] The principle of an optical contrast sensor is as follows: a miniature coaxial fiber optic probe is placed as close as possible to the aperture. Utilizing the principle that the tapered aperture scatters light, the sensor detects whether the intensity of the reflected light is below the threshold for a flat surface. If the end with the tapered aperture faces downwards, the sensor checks whether the intensity of the reflected light is below the threshold for a flat surface; if the end with the chamfer faces downwards, the sensor checks whether the intensity of the reflected light is at the threshold for a flat surface.

[0033] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
