Description

Technical Field

[0001] This utility model relates to the field of screw feeding technology, specifically to an intelligent counting disc screw feeder. Background Technology

[0002] In the field of screw feeding, existing screw feeders typically arrange screws in an orderly manner and then discharge them through the outlet. To count the number of screws discharged, the industry generally installs counters and detection sensors at the outlet of the feeding device to detect the number of screws discharged.

[0003] However, in the actual feeding process, due to reasons such as the screws being fed out too quickly or the adjacent screws being too tightly fitted, the detection sensor often has difficulty accurately identifying each screw, which can easily lead to missed detections or false detections, resulting in counting errors. This seriously affects the accuracy of the counting and causes inconvenience to subsequent production operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent counting disc screw feeder, which solves the problem of inaccurate sensor detection and counting errors caused by screws being fed too quickly or too tightly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent counting disc screw feeder, comprising a disc feeder body, wherein a discharge slide is provided on the disc feeder body, the discharge slide is used to discharge screws, and a downwardly recessed groove is provided in the middle of the discharge slide, the width of the groove is sufficient for the screw stud to pass through, and the width of the groove is insufficient for the screw nut to pass through, so that the screw nut is always located at the top of the discharge slide during the discharge process;

[0006] The top of each side of the discharge chute is equipped with a protruding platform. The distance between the two protruding platforms is enough for the screw stud to pass through, but the distance between the two protruding platforms is not enough for the bolt nut to pass through. Each protruding platform has an inclined feeding part facing the screw feeding direction. The feeding part allows the screw nut to slide smoothly to the top of the protruding platform.

[0007] The top of the protrusion is provided with a detection part, the length of which can accommodate the nut of a screw;

[0008] A detection sensor is mounted above the detection section. The screws on the detection section of the protrusion can have their nuts raised to a certain height. The detection sensor can only detect the nuts of screws at the detection section at this raised height. Screws located below the detection section cannot be detected by the detection sensor.

[0009] Furthermore, the detection sensor is equipped with a cable, which is connected to the counter.

[0010] Furthermore, an installation frame is installed on the outer wall of the discharge chute, and a support frame is provided on the top of the installation frame, on which the detection sensor is installed.

[0011] Furthermore, the support frame has lead screws connected to both sides by threads, and the end of each lead screw is connected to a corresponding protrusion. The lead screws are rotatably connected to the protrusions, and the distance between the protrusions on both sides can be adjusted by rotating the lead screws.

[0012] Furthermore, slide rods are installed on both sides of the support frame, and the axial direction of the slide rods is parallel to the axial direction of the lead screw. The end of each slide rod is connected to a corresponding protrusion.

[0013] Furthermore, the lead screw is provided with a turning block for rotating the lead screw.

[0014] Furthermore, the outer walls of the sliding rods installed on both sides of the support frame are provided with scales.

[0015] Furthermore, the mounting frame is detachably mounted on the outside of the discharge slide. The mounting frame has mounting holes, and bolts are installed in the mounting holes. The discharge slide has screw holes corresponding to the mounting holes. The internal thread of the screw holes matches the external thread of the bolts, and the bolts can be screwed into the screw holes.

[0016] Compared with the prior art, this utility model provides an intelligent counting disc screw feeder, which has the following beneficial effects:

[0017] This intelligent counting disc screw feeder features raised platforms on both sides of the discharge chute. The spacing between these platforms restricts the passage of bolts and nuts, allowing only studs to pass through. Combined with the inclined feeding surface of the raised platforms facing the incoming material direction, the screws and nuts can smoothly slide to the detection section at the top of the raised platforms. The detection section is only long enough to accommodate one screw and nut, and the raised platforms prevent the bolts from sliding down too quickly. Furthermore, by creating a height difference between the screws and nuts on the detection section, the detection sensor can only detect nuts at that height, while screws below the detection section cannot be detected. This effectively avoids missed or false detections caused by screws being discharged too quickly or too tightly, significantly improving the accuracy of screw counting. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 and 6 This utility model discloses an intelligent counting disc screw feeder, comprising a disc feeder body 1, which can be fed by a vibratory feeder. The disc feeder body 1 is provided with a discharge slide 2 for discharging screws 4. At the center of the discharge slide 2, there is a downwardly recessed slot 3. The width of the slot 3 is set to allow only the stud of the screw 4 to pass through, but not the nut. With this structural design, when the screw 4 moves within the discharge slide 2, its stud can be embedded in the slot 3, while the nut is blocked by the edge of the slot 3. This ensures that the nut of the screw 4 remains at the top of the discharge slide 2 throughout the entire discharge process, providing a stable structural foundation for subsequent inspection operations.

[0027] At the top of each side of the discharge chute 2, there are raised platforms 5. The gap between the raised platforms 5 on both sides is only wide enough for the stud of the screw 4 to pass through, while the nut of the screw 4 cannot pass through because its size is larger than the gap, thus limiting the movement of the screw 4.

[0028] Each raised platform 5 has an inclined feeding section 6 facing the direction of the screw 4. The surface of the feeding section 6 is smooth, and when the screw 4 is conveyed to the raised platform 5 along the discharge slide 2, its nut can smoothly slide to the top of the raised platform 5 along the inclination angle of the feeding section 6. While the feeding section 6 is provided on the raised platform 5 facing the direction of the screw 4, a discharging section 18 is also provided on the other side of the raised platform 5. This discharging section 18 is inclined in the opposite direction to the feeding section 6. In this way, after the nut of the screw 4 slides to the detection section 7 at the top of the raised platform 5 via the feeding section 6, it can continue to be conveyed forward along the inclination direction of the discharging section 18, allowing the screw 4 to smoothly complete the detection and enter the subsequent discharge process, ensuring the continuity of the overall feeding process.

[0029] The top of the protrusion 5 is provided with a detection part 7, the length of which is set to accommodate only one screw 4 nut, ensuring that only one screw 4 is in the detection position at any given time.

[0030] Above the detection unit 7, a detection sensor 10 is mounted. This sensor 10 can be a photoelectric sensor, a vision sensor, or a magnetic sensor, used to detect the screws 4. When the screw 4's nut slides from the loading unit 6 to the detection unit 7, it rises to a specific height. The detection range of the detection sensor 10 is limited to this height range, allowing it to detect only screws 4 nutes that are within the detection unit 7 and have reached that height. Screws 4 located below the detection unit 7 and not reaching this height cannot be detected by the detection sensor 10, thus achieving precise detection of each screw 4 individually.

[0031] The raised platform 5 plays a dual role in the device: on the one hand, its raised structure can block the screws 4 conveyed along the discharge slide 2, slowing down the downward speed of the screws 4 and preventing the screws 4 from being discharged too quickly and affecting subsequent detection; on the other hand, when the nut of the screw 4 slides along the feeding part 6 of the raised platform 5, the inclined design of the feeding part 6 can guide the nut to the detection part 7 at the top of the raised platform 5, so that the nut is raised to a specific height for accurate detection by the detection sensor 10.

[0032] To count the number of screws 4 produced, a dedicated cable 11 is connected to the detection sensor 10. The other end of the cable 11 is connected to a counter, forming a complete signal transmission path. When the detection sensor 10 detects a screw 4 nut at a specific height in the detection section 7, it transmits the detection signal to the counter in real time via the cable 11. The counter then automatically counts each screw 4 that passes below the detection sensor 10 based on the received signal, thereby accurately recording the total number of screws 4 produced.

[0033] like Figure 2-5 As shown, in order to achieve stable installation of the detection sensor 10 and flexible adjustment of the distance between the protrusion 5, the device has a mounting frame 8 fixedly installed on the outer wall of the discharge slide 2. The top of the mounting frame 8 is integrally formed or fixedly connected to the support frame 9 by bolts 16. The detection sensor 10 is securely installed on the support frame 9 by bolts 16 or snap-fit ​​structure, ensuring that the detection sensor 10 is always aligned with the detection part 7 on the top of the protrusion 5, thus ensuring detection accuracy.

[0034] To accommodate the testing requirements of screws 4 of different specifications, both sides of the support frame 9 are threadedly connected to the lead screw 12 through threaded holes. One end of each lead screw 12 extends to the outside of the support frame 9, and the other end is rotatably connected to the corresponding protrusion 5 through a bearing or shaft structure. That is, the lead screw 12 can rotate around its own axis, and the rotation will not drive the protrusion 5 to rotate synchronously. When it is necessary to adjust the distance between the two protrusions 5, the operator can rotate the lead screw 12, and by utilizing the threaded engagement between the lead screw 12 and the support frame 9, drive the protrusion 5 to move closer or further away along the axis of the lead screw 12, thereby precisely adjusting the distance between the two protrusions 5 to accommodate the studs of different sizes of screws 4.

[0035] Meanwhile, to prevent the raised platform 5 from shifting or wobbling during adjustment, slide rods 14 are also installed on both sides of the support frame 9. The axis of the slide rod 14 is parallel to the axis of the lead screw 12, and the slide rod 14 and the support frame 9 are in sliding fit. One end of each slide rod 14 is fixedly connected to the corresponding raised platform 5. When the raised platform 5 moves with the lead screw 12, the slide rod 14 will slide synchronously along its axis to provide guidance and support for the raised platform 5, ensuring that the raised platform 5 always moves smoothly in the preset direction and maintaining the positional stability of the detection unit 7.

[0036] To facilitate the operator's rotation of the lead screw 12, a screwing block 13 is fixedly sleeved at the end of the lead screw 12 located outside the support frame 9. The outer wall of the screwing block 13 can be provided with anti-slip texture or polygonal structure (such as hexagon, octagon, etc.) to facilitate the operator's rotation of the lead screw 12 with the help of tools or directly by hand, thereby improving the convenience of adjustment operation.

[0037] Furthermore, clear scales are engraved on the outer walls of the slide rods 14 installed on both sides of the support frame 9, along the axial direction of the slide rods 14. The unit of the scale can be set to millimeters (mm) or other commonly used length units. When adjusting the spacing of the protrusions 5, the operator can intuitively grasp the moving distance of the protrusions 5 on both sides by observing the scales on the slide rods 14, thereby achieving precise control of the spacing and further improving the device's adaptability to screws 4 of different specifications, reducing the number of trial and error attempts during the adjustment process.

[0038] To facilitate the disassembly, maintenance, and position adjustment of the mounting frame 8, this device employs a detachable structure to assemble the mounting frame 8 onto the outside of the discharge slide 2. Specifically, a through mounting hole 15 is provided at the corresponding position of the mounting frame 8, and a bolt 16 is fitted into the mounting hole 15. Simultaneously, on the outer wall of the discharge slide 2, a threaded hole 17 with an internal thread structure is provided at the position corresponding to the mounting hole 15, and the internal thread parameters of the threaded hole 17 are perfectly matched with the external thread parameters of the bolt 16, forming a precise threaded fit.

[0039] When the mounting frame 8 needs to be installed, the operator only needs to align the mounting hole 15 of the mounting frame 8 with the screw hole 17 of the discharge slide 2, then insert the bolt 16 into the mounting hole 15 and turn it clockwise, so that the bolt 16 is gradually screwed into the screw hole 17 until the head of the bolt 16 is tightly attached to the surface of the mounting frame 8, thus achieving a stable connection between the mounting frame 8 and the discharge slide 2. When the mounting frame 8 needs to be disassembled for maintenance or replacement, simply turn the bolt 16 counterclockwise to remove the bolt 16 from the screw hole 17 and the mounting hole 15, and the mounting frame 8 can be easily separated from the discharge slide 2. The entire disassembly and assembly process does not require complicated tools and is convenient and efficient.

[0040] The mounting frame 8 can be designed in various sizes. Different sizes of mounting frames 8 differ in parameters such as length, width, and the position of mounting holes 15. They can be selected and assembled according to the specific dimensions of the discharge slide 2 (such as slide width, outer wall shape, etc.) in actual applications, ensuring that the mounting frame 8 can achieve precise matching and stable connection with the discharge slide 2 of different sizes, thereby meeting the diverse needs of screw 4 feeding scenarios and expanding the applicability of the device.

[0041] In summary, this intelligent counting disc screw feeder operates as follows: during use, screws 4 are organized by the disc feeder body 1 and then enter the discharge chute 2, where they are conveyed in an orderly manner. When a screw 4 moves to the raised platform 5, its nut first contacts the inclined feeding section 6 of the raised platform 5 facing the incoming material direction, and then smoothly slides along the feeding section 6 to the detection section 7 at the top of the raised platform 5. Since the detection section 7 can only accommodate one screw 4 nut at a time, only one screw 4 nut is in the detection section 7 at a time. Simultaneously, the blocking effect of the raised platform 5 slows down the downward speed of the screws 4, preventing continuous stacking. At this point, the screw 4 nut located in the detection section 7 is lifted to a specific height by the structure of the raised platform 5, and the detection sensor 10 only responds to nuts at that height, immediately identifying and sending a detection signal, which is transmitted to the counter via the cable 11. The counter receives the signal and completes one count. After counting is completed, the screw 4 nut will slide from the detection section 7 to the lower part on the other side of the protrusion 5 and continue to be conveyed along the discharge slide 2. The subsequent screws 4 will repeat the above process in turn to achieve continuous and accurate counting of screws 4.
