Description

Technical Field

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

[0002] Screws are a common type of fastener, usually made of metal, with a threaded rod-like structure. The main function of a screw is to fasten two or more objects together. By rotating the screw, its threads engage with the threads of a nut or the internal threads of the hole of the object being fastened, thus achieving a fastening. In modern manufacturing and assembly industries, screws, as a basic fastener, are widely used in the assembly process of various equipment and products, thus requiring a screw feeder.

[0003] Traditional screw feeders require manual placement of screws one by one onto the conveyor in a uniform direction. This method is time-consuming and reduces work efficiency. In addition, manual operation is prone to errors such as misplacement, omission, or inconsistent orientation, which leads to difficulties in subsequent assembly. These errors not only affect assembly quality but may also result in material waste and production delays. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a screw feeder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screw feeder includes a housing with an open top. A right-angled triangular base is fixed to one end of the inner wall of the housing, and the inclined surface of the right-angled triangular base is arc-shaped. A pushing mechanism for pushing screws is provided at the other end of the inner wall of the housing. A through groove is formed at the end of the outer wall of the housing away from the right-angled triangular base. A first conveyor belt is provided at the end of the outer wall of the housing near the through groove, and the first conveyor belt is located below the through groove. A first rotating mechanism for rotating the first conveyor belt is provided on one side of the outer wall of the housing. A second L-shaped plate is provided on one side of the outer wall of the housing. Two connecting rods are obliquely fixed to the inner wall of one end of the second L-shaped plate, and the two connecting rods are arranged in parallel. A vibration mechanism for vibrating the two connecting rods is provided on the outer wall of the second L-shaped plate. A connecting seat is fixed to one side of the housing, and the connecting seat is located below the lowest point of the two connecting rods. A through hole is formed at the top of the connecting seat, and a section of the top of the connecting seat near the through hole is provided. An arc-shaped plate is fixed in place. A second conveyor belt is installed on one side of the outer wall of the housing. The second conveyor belt is located below the connecting seat, and the distance between the top of the second conveyor belt and the bottom of the connecting seat is the length of the screw. A second rotating mechanism for rotating the second conveyor belt is provided on one side of the outer wall of the housing. During use, the screw can be pushed from the through slot to the top of the first conveyor belt by the pushing mechanism. The first conveyor belt is then rotated by the first rotating mechanism, which transports the screw to the space between the two connecting rods. With the help of the vibration mechanism, the screw can automatically adjust its direction during the downward movement and enter the top of the second conveyor belt through the through hole. The second rotating mechanism then drives the second conveyor belt to rotate, causing the screw to tilt in the opposite direction to the rotation direction of the second conveyor belt. This ensures that the screw shaft faces the same direction. The entire process requires no manual handling, saving time, improving work efficiency, and ensuring assembly quality.

[0007] Preferably, the pushing mechanism includes a right-angled triangular block, which is disposed at the other end of the inner side wall of the box. Two hydraulic push rods are fixed at the bottom of the box, and the output ends of the two hydraulic push rods are fixed to the bottom of the right-angled triangular block. Since the top of the right-angled triangular block and the bottom of the right-angled triangular base are flush, some screws are located on the inclined surface of the right-angled triangular block. During conveying, the two hydraulic push rods are driven to move the right-angled triangular block upward. When the bottom of the right-angled triangular block and the lower edge of the through groove are flush, the screws located on the inclined surface of the right-angled triangular block roll down from the through groove to the top of the first conveyor belt.

[0008] Preferably, the first rotating mechanism includes a first L-shaped plate, which is fixed to the outer wall of the box. One end of the first L-shaped plate is fixed to a second L-shaped plate. The inner walls of both ends of the first conveyor belt are fitted with first rotating shafts. One end of each of the two first rotating shafts is rotatably connected to the first L-shaped plate, and both ends of the two first rotating shafts are rotatably connected to the outer wall of the box. A first motor is fixed to the outer wall of one end of the first L-shaped plate, and the output shaft of the first motor is fixed to one of the first rotating shafts. A guide plate is inclinedly fixed to the end of the first L-shaped plate away from the first motor, and the guide plate is located above the two connecting rods. The first motor drives one of the first rotating shafts to rotate, which in turn drives the first conveyor belt to rotate. At this time, the screw moves towards the second L-shaped plate. When the screw is conveyed to one end of the first conveyor belt, it slides down between the two connecting rods through the guide plate.

[0009] Preferably, the vibration mechanism includes a vibration motor, which is fixed to the outer wall of one end of the second L-shaped plate. When the vibration motor is powered on, it generates vibration, causing the two connecting rods to be in a vibrating state. In this way, the screw located between the two connecting rods will move downward along the inclined direction of the two connecting rods.

[0010] Preferably, the second rotating mechanism includes a third L-shaped plate, which is fixed to the outer wall of the housing and located below the second conveyor belt. Second rotating shafts are fitted onto the inner walls of both ends of the second conveyor belt. One end of each of the two second rotating shafts is rotatably connected to the housing, and the other end is rotatably connected to the inner wall of the third L-shaped plate. A second motor is fixed to the outer wall of the third L-shaped plate, and the output end of the second motor is fixed to one of the second rotating shafts. When the screw moves to the lowest point of the two connecting rods, under the action of the arc-shaped plate, the screw will fall vertically into the through hole. Inside, since the distance between the connecting seat and the second conveyor belt is the length of the screw, the screw that enters the through hole will stand on top of the second conveyor belt and be inside the two baffles. At this time, the power switch of the second motor is turned on, driving the second motor to drive one of the second shafts to rotate, which in turn drives the second conveyor belt to rotate. When the second conveyor belt rotates, the screw that was originally standing will tilt in the opposite direction to the rotation of the second conveyor belt, that is, the screw shaft will be aligned in the direction of rotation of the second conveyor belt.

[0011] Preferably, two baffles are symmetrically arranged on the top of the second conveyor belt, and both baffles are fixed to the bottom of the connecting seat. The two baffles limit the screws, preventing them from rolling off the second conveyor belt and ensuring the consistency of the screws' orientation.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. During use, this device pushes screws from the through slot to the top of the first conveyor belt via a pushing mechanism. The first rotating mechanism then drives the first conveyor belt to rotate, transporting the screws between the two connecting rods. A vibration mechanism, in conjunction with this mechanism, allows the screws to automatically adjust their direction as they slide down. The screws then pass through the through hole to the top of the second conveyor belt, where the second rotating mechanism drives the second conveyor belt to rotate, causing the screws to tilt in the opposite direction to the rotation of the second conveyor belt. This ensures that the screw shafts face the same direction. The entire process requires no manual intervention, saving time, improving work efficiency, and guaranteeing assembly quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-5A screw feeder includes a housing 1 with an open top. A right-angled triangular base 2 is fixed to one end of the inner wall of the housing 1, and the inclined surface of the right-angled triangular base 2 has an arc-shaped structure. A pushing mechanism for pushing screws is provided at the other end of the inner wall of the housing 1. A through groove 3 is opened at the end of the outer wall of the housing 1 away from the right-angled triangular base 2. A first conveyor belt 10 is provided at the end of the outer wall of the housing 1 near the through groove 3, and the first conveyor belt 10 is located below the through groove 3. A rotating mechanism is provided on one end of the outer wall of the housing 1. The first rotating mechanism of the first conveyor belt 10 includes a second L-shaped plate 5 on one side of the outer wall of the housing 1. Two connecting rods 13 are fixed obliquely to the inner wall of one end of the second L-shaped plate 5, and the two connecting rods 13 are arranged in parallel. A vibration mechanism for vibrating the two connecting rods 13 is provided on the outer wall of the second L-shaped plate 5. A connecting seat 15 is fixed on one side of the housing 1, and the connecting seat 15 is located below the lowest end of the two connecting rods 13. A through hole 16 is opened on the top of the connecting seat 15, and the top of the connecting seat 15 is fixed near the through hole 16. The device includes an arc-shaped plate 17 and a second conveyor belt 19 on one side of the outer wall of the housing 1. The second conveyor belt 19 is located below the connecting seat 15, and the distance between the top of the second conveyor belt 19 and the bottom of the connecting seat 15 is the length of the screw. A second rotating mechanism for rotating the second conveyor belt 19 is provided on one side of the outer wall of the housing 1. During use, the screw can be pushed from the through groove 3 to the top of the first conveyor belt 10 by the pushing mechanism, and the first conveyor belt 10 is rotated by the first rotating mechanism to transport the screw to the space between the two connecting rods 13. With the help of the vibration mechanism, the screw can automatically adjust its direction during the downward movement and enter the top of the second conveyor belt 19 through the through hole 16. Then, the second rotating mechanism drives the second conveyor belt 19 to rotate, causing the screw to tilt in the opposite direction to the rotation direction of the second conveyor belt 19. This ensures that the screw shank faces the same direction. The entire process does not require manual handling, saving time, improving work efficiency, and ensuring assembly quality.

[0022] Furthermore, the pushing mechanism includes a right-angled triangular block 7, which is located at the other end of the inner wall of the housing 1. Two hydraulic push rods 8 are fixed at the bottom of the housing 1, and the output ends of the two hydraulic push rods 8 are fixed to the bottom of the right-angled triangular block 7. Since the top of the right-angled triangular block 7 and the bottom of the right-angled triangular seat 2 are flush, some screws are located on the inclined surface of the right-angled triangular block 7. During conveying, the two hydraulic push rods 8 are driven to move the right-angled triangular block 7 upward. When the bottom of the right-angled triangular block 7 and the lower edge of the through groove 3 are flush, the screws located on the inclined surface of the right-angled triangular block 7 roll down from the through groove 3 to the top of the first conveyor belt 10.

[0023] Furthermore, the first rotating mechanism includes a first L-shaped plate 4, which is fixed to the outer wall of the housing 1. One end of the first L-shaped plate 4 is fixed to the second L-shaped plate 5. The inner walls of both ends of the first conveyor belt 10 are fitted with first rotating shafts 9. One end of each of the two first rotating shafts 9 is rotatably connected to the first L-shaped plate 4, and both ends of each of the two first rotating shafts 9 are rotatably connected to the outer wall of the housing 1. A first motor 12 is fixed to one end of the outer wall of the first L-shaped plate 4, and the output shaft of the first motor 12 is fixed to one of the first rotating shafts 9. A guide plate 11 is inclinedly fixed to the end of the first L-shaped plate 4 away from the first motor 12, and the guide plate 11 is located above the two connecting rods 13. The first motor 12 drives one of the first rotating shafts 9 to rotate, which in turn drives the first conveyor belt 10 to rotate. At this time, the screw moves towards the second L-shaped plate 5. When the screw is conveyed to one end of the first conveyor belt 10, it slides down between the two connecting rods 13 through the guide plate 11.

[0024] Furthermore, the vibration mechanism includes a vibration motor 14, which is fixed to the outer wall of one end of the second L-shaped plate 5. When the vibration motor 14 is powered on, it generates vibration, causing the two connecting rods 13 to be in a vibrating state. In this way, the screw located between the two connecting rods 13 will move downward along the inclined direction of the two connecting rods 13.

[0025] Furthermore, the second rotating mechanism includes a third L-shaped plate 6, which is fixed to the outer wall of the housing 1 and located below the second conveyor belt 19. Second rotating shafts 18 are fitted onto the inner walls of both ends of the second conveyor belt 19. One end of each second rotating shaft 18 is rotatably connected to the housing 1, and the other end is rotatably connected to the inner wall of the third L-shaped plate 6. A second motor 21 is fixed to the outer wall of the third L-shaped plate 6, and the output end of the second motor 21 is fixed to one of the second rotating shafts 18. When the screw moves to the lowest point of the two connecting rods 13, under the action of the arc-shaped plate 17, the screw will fall vertically into the through hole 16. The distance between the connecting seat 15 and the second conveyor belt 19 is the length of the screw. The screw that enters the through hole 16 will stand on top of the second conveyor belt 19 and be inside the two baffles 20. At this time, the power switch of the second motor 21 is turned on, and the power switch of the second motor 21 is turned on, which drives one of the second shafts 18 to rotate. In conjunction with the other second shaft 18, the second conveyor belt 19 is rotated. When the second conveyor belt 19 rotates, the screw that was originally standing will tilt over in the opposite direction to the rotation direction of the second conveyor belt 19. That is, the screw shaft will be aligned in the same direction as the rotation direction of the second conveyor belt 19.

[0026] Furthermore, two baffles 20 are symmetrically arranged on the top of the second conveyor belt 19, and both baffles 20 are fixed to the bottom of the connecting seat 15. The two baffles 20 limit the screws, preventing the screws from rolling off the second conveyor belt 19, while also ensuring the consistency of the screw orientation.

[0027] Working principle: During use, screws are placed inside the housing 1. Since the top of the right-angled triangular block 7 and the bottom of the right-angled triangular base 2 are flush, some screws are located on the inclined surface of the right-angled triangular block 7. During transport, the two hydraulic push rods 8 are driven to move the right-angled triangular block 7 upwards. When the bottom of the right-angled triangular block 7 is flush with the lower edge of the through groove 3, the screws located on the inclined surface of the right-angled triangular block 7 roll down from the through groove 3 to the top of the first conveyor belt 10. At this time, the power switch of the first motor 12 is turned on, driving the first motor 12. One of the first rotating shafts 9 is driven to rotate, which in turn drives the first conveyor belt 10 to rotate. At this time, the screw moves towards the second L-shaped plate 5. When the screw is conveyed to one end of the first conveyor belt 10, it slides down between the two connecting rods 13 via the guide plate 11. Since the distance between the two connecting rods 13 is less than the size of the screw head, the screw's screw shaft is in a downward position under the screw's own weight. Simultaneously, the power switch of the vibration motor 14 is turned on. When the vibration motor 14 is powered on, it generates vibration, causing the two... When the connecting rod 13 is vibrating, the screw located between the two connecting rods 13 will move downwards along the inclined direction of the two connecting rods 13. When the screw moves to the lowest point of the two connecting rods 13, under the action of the arc plate 17, the screw will fall vertically into the through hole 16. Since the distance between the connecting seat 15 and the second conveyor belt 19 is the length of the screw, the screw that enters the through hole 16 will stand on top of the second conveyor belt 19 and be inside the two baffles 20. At this time, the power switch of the second motor 21 is turned on, driving the second motor 21 to drive one of the second rotating shafts 18 to rotate. In conjunction with the other second rotating shaft 18, the second conveyor belt 19 will rotate. When the second conveyor belt 19 rotates, the screw that was originally standing will tilt in the opposite direction to the rotation direction of the second conveyor belt 19. That is, the screw shank will be aligned in the same direction as the rotation direction of the second conveyor belt 19. During the process, no manual operation is required, saving time and improving work efficiency. At the same time, it also ensures that the screw shank is aligned, improving the assembly quality.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
