Description

Technical Field

[0001] This utility model belongs to the field of screw processing technology, and in particular relates to a screw processing feeding mechanism. Background Technology

[0002] The screw processing feeding mechanism is an automated conveying device, mainly used to achieve efficient and precise material conveying during screw production or assembly, thereby replacing manual feeding, significantly improving production efficiency, and ensuring consistent processing quality. This mechanism typically has functions such as multi-specification compatibility, jam warning, and automatic sorting, and is widely used in large-volume automated screw production scenarios in industries such as electronics, automobiles, and hardware.

[0003] Chinese patent application No. 202321220019.8 discloses a screw processing feeding mechanism, including a base, a flat plate on the base, a collection box on the flat plate, and a feeding component inside the collection box. The feeding component includes a frame, a motor at the bottom of the frame, and rollers at the motor output end. Multiple rollers are located inside the frame and are connected by a belt. The belt has several equally spaced baffles on its outer wall. A discharge port is located on the upper side wall of the frame, and a discharge channel is located opposite the discharge port. The motor drives the rollers to rotate, and the belt drives the rollers to rotate. The baffles on the belt feed the screws from the collection box to the top, where they are discharged from the discharge port. The screws are then fed along the discharge channel to the drop outlet, thus achieving feeding. This solution has a novel structure, is easy to operate, eliminates the need for manual feeding, saves time and labor, reduces labor costs, facilitates subsequent screw processing, and improves processing efficiency.

[0004] Existing screw feeding mechanisms still have some problems during use. For example, they cannot vibrate and sort screws during feeding, resulting in messy screws being sent to the next process, which seriously affects the subsequent processing accuracy and assembly efficiency. Furthermore, they are prone to jamming during feeding, which increases the failure rate and maintenance cost of the feeding mechanism.

[0005] To address these issues, we provide a screw processing feeding mechanism. Utility Model Content

[0006] The purpose of this invention is to provide a screw processing feeding mechanism that can orient and arrange screws, solving the problem that existing screw processing feeding mechanisms cannot orient and sort screws during conveying, thus affecting subsequent processing accuracy and assembly efficiency.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a screw processing feeding mechanism, comprising a base plate, a support plate fixedly connected to one side of the top of the base plate, a slider slidably connected to the surface of the support plate, a vibration box fixedly connected to one side of the slider, a guide block fixedly connected to one side of the inner wall of the vibration box, a conveying box fixedly connected to one side of the vibration box, a limit plate fixedly connected inside the conveying box, a horizontal plate fixedly connected to the top of one side of the support plate, a damper fixedly connected to the top of the horizontal plate, the top of the damper fixedly connected to the bottom of the vibration box, a drive motor fixedly connected to one side of the top of the base plate, a housing provided on one side of the top of the base plate, a circular plate provided inside the housing, a drive rod fixedly connected to the output end of the drive motor, the top of the drive rod fixedly connected to the bottom of the circular plate, a placement groove provided inside the circular plate, a rotating rod provided on the other side of the top of the base plate, a rotating plate fixedly connected to the top of the rotating rod, a pushing block fixedly connected to the top of the rotating plate, a vibration block fixedly connected to the bottom of the vibration box, a first pulley fixedly connected to the surface of the drive rod, and a second pulley fixedly connected to the surface of the rotating rod.

[0009] The present invention is further configured such that a bracket is fixedly connected to the top of the outer shell, a cylinder is fixedly connected to the top of the bracket, a push plate is fixedly connected to the output end of the cylinder, and a photoelectric sensor is fixedly connected to the inner wall of the bracket.

[0010] The present invention is further configured such that a sliding groove is provided on one side of the top of the bracket, and the push plate is slidably connected inside the sliding groove.

[0011] The present invention is further configured such that the conveying box has T-shaped grooves at the connection of the vibration box and on one side of the conveying box, and the T-shaped grooves are used for directional conveying of screws.

[0012] The present invention is further configured such that a through groove is provided at the bottom of the outer shell, and the transmission rod is rotatably connected inside the through groove.

[0013] The present invention is further configured such that the photoelectric sensor is model OMRON EE-SX671, and the photoelectric sensor is used to detect the position of the screw in real time.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model achieves the purpose of vibration sorting by setting up a vibrating block and a pushing block. In conjunction with the circular plate and conveyor, it achieves efficient directional conveying of screws. The guide block set in the vibration box and the bottom vibrating block cooperate to ensure that the screws obtain a stable vibration frequency during the conveying process. With the setting of the T-slot, it can ensure that the screws enter the processing station with a uniform orientation. The drive motor can drive the rotating plate and the pushing block to rotate simultaneously through the first pulley and the second pulley. The damper can absorb the impact force generated during vibration, thereby achieving the purpose of vibration sorting and effectively solving the problem of screw jamming caused by uneven vibration in traditional feeding mechanisms.

[0017] 2. This invention achieves real-time detection and precise pushing of screw positions through the use of photoelectric sensors and cylinders. When the photoelectric sensor detects that the screw has reached the designated position, the cylinder immediately drives the push plate to move, ensuring that the screw is quickly and accurately pushed into the next process, significantly improving the level of automation in feeding and production efficiency. Simultaneously, the connection between the feed pipe and the vibrating box allows the screws to enter the vibration sorting area evenly, while the circular plate and placement groove structure inside the outer shell further optimizes the temporary storage and conveying of the screws, thereby achieving the purpose of directional sorting of the screws.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The base plate 11 is fixedly connected with a support leg, the bottom of which is fixedly connected to the top of the base plate 1. T-shaped grooves are also provided on both sides of the outer shell 11. The screws can be easily transported into the placement groove 14 through the T-shaped grooves and can also be easily pushed to the next process. A circular plate 12 is provided inside the outer shell 11. A transmission rod 13 is fixedly connected to the output end of the transmission motor 10. The top of the transmission rod 13 is fixedly connected to the bottom of the circular plate 12. A placement groove 14 is provided inside the circular plate 12. The placement groove 14 can easily store the screws and transfer them to the next process. A rotating rod 15 is provided on the other side of the top of the base plate 1.

A first pulley 23 is fixedly connected to the surface of the transmission rod 13. A second pulley 24 is fixedly connected to the surface of the rotating rod 15. The first pulley 23 and the second pulley 24 are both connected by belt drive.

[0029] Example 2

[0030] Please see Figures 1-5Based on Embodiment 1, a bracket 19 is fixedly connected to the top of the outer shell 11, and a cylinder 20 is fixedly connected to the top of the bracket 19. A push plate 21 is fixedly connected to the output end of the cylinder 20. The cylinder 20 can push the screw to move through the push plate 21, thereby moving it to the next area. A photoelectric sensor 22 is fixedly connected to the inner wall of the bracket 19. The photoelectric sensor 22 senses the position or state of an object by emitting a light beam and detecting the reflection, transmission, or obstruction of light by the target object. Its core consists of a light-emitting element, a receiver, and a signal processing circuit. It uses changes in light signals to trigger a switch or output a signal. A sliding groove is opened on one side of the top of the bracket 19, and the push plate 21 is slidably connected inside the sliding groove. T-shaped grooves are opened at the connection between the conveyor box 6 and the vibration box 4, and on one side of the conveyor box 6. The T-shaped grooves are used for directional conveying of the screw. A through groove is opened at the bottom of the outer shell 11, and the transmission rod 13 is rotatably connected inside the through groove. The photoelectric sensor 22 is of model OMRON. The EE-SX671 uses a photoelectric sensor 22 to detect the position of the screw in real time, making it easy to push it out. A support frame is fixedly connected to the top side of the vibration box 4, and a feed pipe is fixedly connected inside the support frame. The bottom of the feed pipe is connected to the top of the vibration box 4.

[0031] The working principle of this utility model is as follows: When screws need to be oriented and sorted for conveying, the screws first enter the vibrating box 4 through the feed pipe. Then, the user starts the drive motor 10 through the external controller. The drive motor 10 drives the drive rod 13 to rotate, the drive rod 13 drives the first pulley 23 to rotate, the first pulley 23 drives the second pulley 24 to rotate through the belt, the second pulley 24 drives the rotating rod 15 to rotate, the rotating rod 15 drives the rotating plate 16 to rotate, and the rotating plate 16 drives the pushing block 17 to rotate. When the pushing block 17 contacts the vibrating block 18... The push block 17 moves upward via the vibrating block 18, and the vibrating block 18 pushes the vibrating box 4 upward. When the vibrating box 4 moves upward, it pulls the damper 9. When the push block 17 separates from the vibrating block 18, the damper 9 will use its own elasticity to drive the vibrating box 4 to reset and absorb the impact force of the vibrating box 4 to reduce noise and wear. This reciprocating motion can achieve the purpose of reciprocating vibration. Thus, through vibration and the guidance of the guide block 5, the screws are oriented and enter the T-shaped groove of the conveying box 6 to ensure uniform orientation and are conveyed to the placement groove 14 inside the circular plate 12.

[0032] At the same time, the transmission rod 13 drives the circular plate 12 to rotate, and the circular plate 12 drives the screw to rotate through the placement groove 14. When the screw rotates to the preset position, the photoelectric sensor 22 will detect the screw, and then the photoelectric sensor 22 will start the cylinder 20 through an electrical signal. The cylinder 20 pushes the screw to move through the push plate 21, so that it moves to the next process. Finally, the fully automated process of screw feeding from disordered feeding to orderly and efficient conveying is realized, and the risk of jamming is further avoided.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
