[0001] This utility model relates to the field of screw sorting technology, and more specifically, to a screw sorting mechanism. Background Technology

[0002] A screw is a tool that uses the physical and mathematical principles of inclined plane rotation and friction to gradually fasten objects and machine parts. During production, screws of different types may be mixed together, which requires a screw sorting mechanism to classify and sort the screws of different types.

[0003] Existing screw sorting mechanisms can only sort screws by length. However, screws of the same length often have different stud thicknesses. Existing screw sorting mechanisms cannot sort screws with different stud thicknesses. For screws with different stud thicknesses, secondary sorting by manual labor or other equipment is required, resulting in low sorting efficiency.

[0004] Therefore, a screw screening mechanism is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a screw screening mechanism to solve the problems mentioned in the background art.

The detection component is installed below the first guide plate, and the collection components are all fixedly installed below the second guide plate.

[0009] Preferably, each adjustment component includes a turntable, a lead screw, and a mounting groove. One end of the lead screw is rotatably disposed on one side of a baffle, and the turntable is fixedly mounted on the side of the lead screw away from the baffle. The mounting groove is opened on one side of the mounting bracket, and the mounting groove and the lead screw are connected by threaded engagement.

[0010] Preferably, each feeding assembly includes a feeding hopper and two limiting plates. The feeding hopper is located directly below the drop trough and is fixedly connected to the bottom surface of the mounting frame. The two limiting plates are respectively fixed on both sides inside the feeding hopper.

[0011] Preferably, the detection components include a mounting plate and multiple position sensors. The mounting plate is fixedly installed between the base plate and the first guide plate, and the multiple position sensors are fixedly installed on one side of the mounting plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example 1

[0027] As attached Figures 1 to 6 The screw screening mechanism shown includes a base plate 1 and a vertical plate 2, as well as a first screening component and a plurality of second screening components.

[0028] The first screening component includes a mounting frame 5, a chute 19, multiple drop troughs 3, multiple baffles 4, multiple adjusting components, and multiple feeding components. The mounting frame 5 is fixedly installed above the vertical plate 2. The chute 19 is opened on one side above the mounting frame 5, and the size of the chute 19 matches the size of the nut. Multiple drop troughs 3 are evenly opened on the side of the mounting frame 5 away from the chute 19. Each baffle 4 is slidably set in a drop trough 3, and the top surface of the baffle 4 is flush with the top surface of the mounting frame 5. Each adjusting component is set on one side of a baffle 4 and is used to adjust the position of the baffle 4 so that the length of the drop trough 3 can be changed. Each feeding component is located directly below a drop trough 3 and is used to guide and transport the screws after one screening.

[0029] Each second screening component includes a first guide plate 7, a second guide plate 8, a detection component, a collection component, and multiple sliding grooves 6. The first guide plate 7 is located below the feeding component, and the second guide plate 8 is fixed to one side of the first guide plate 7. Specifically, a mounting rod 22 for supporting the second guide plate 8 is fixed below the side of the second guide plate 8 away from the first guide plate 7. Multiple sliding grooves 6 are opened between the first guide plate 7 and the second guide plate 8. Specifically, the first guide plate 7 and the second guide plate 8 have a V-shaped structure, and the ends of the first guide plate 7 and the second guide plate 8 away from the feeding hopper 11 are inclined downwards. A sealing plate 23 is fixed to the ends of the first guide plate 7 and the second guide plate 8 away from the feeding hopper 11. The sealing plate 23 is used to limit and block the screws. The detection component is installed below the first guide plate 7, and the collection component is fixedly installed below the second guide plate 8.

[0030] By using multiple sliding grooves 6, screws of the same length but different thicknesses can be screened a second time, thereby separating screws with different thicknesses of studs. Example 2

[0031] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details:

[0032] In a preferred embodiment, each adjustment component includes a turntable 20, a lead screw 9, and a mounting groove 10. One end of the lead screw 9 is rotatably disposed on one side of the baffle 4, and the turntable 20 is fixedly installed on the side of the lead screw 9 away from the baffle 4. The mounting groove 10 is opened on one side of the mounting bracket 5, and the mounting groove 10 and the lead screw 9 are connected by thread engagement.

[0033] By placing the screw horizontally at the higher end of the mounting bracket 5, the nut at the top of the screw enters the groove 19 on the mounting bracket 5. Since the top surface of the mounting bracket 5 is inclined, when the nut at the top of the screw enters the groove 19, it will roll towards the lower end of the mounting bracket 5. Screws of different sizes will pass through multiple drop grooves 3 when rolling. The length of each drop groove 3 is controlled by a baffle 4 on one side. When screws of different lengths pass through the drop groove 3, the shorter screws will enter the drop groove 3 of the appropriate length first and fall, while screws of other lengths will enter the corresponding drop groove 3 respectively, thus achieving the screening of screws of different lengths.

[0034] When the position of the baffle 4 needs to be adjusted, the turntable 20 is rotated to drive the lead screw 9 to rotate. Since the lead screw 9 and the mounting groove 10 are meshed with each other, the lead screw 9 can drive the baffle 4 to slide inside the drop groove 3 when it rotates, so as to adjust the position of the baffle 4. According to different usage conditions, multiple drop grooves 3 are arranged in an order of gradual extension.

[0035] In a preferred embodiment, each feeding assembly includes a feeding hopper 11 and two limiting plates 12. The feeding hopper 11 is located directly below the drop trough 3 and is fixedly connected to the bottom surface of the mounting frame 5. The two limiting plates 12 are fixed to both sides inside the feeding hopper 11. It should be noted that the end of the feeding hopper 11 away from the mounting frame 5 is inclined downwards.

[0036] The screws that enter the drop groove 3 will enter the feed hopper 11. During the fall, they will pass through two limiting plates 12 installed inside the feed hopper 11. The two limiting plates 12 are installed in a figure-eight shape to guide the screws, so that the screws slide out vertically. The screws that slide out vertically will enter the space between the first guide plate 7 and the second guide plate 8 through the feed hopper 11.

[0037] In a preferred embodiment, the detection components all include a mounting plate 13 and a plurality of position sensors 14. The mounting plate 13 is fixedly installed between the base plate 1 and the first guide plate 7. In order to support the first guide plate 7, the mounting plate 13 is fixedly installed on one side of the mounting plate 13, and each position sensor 14 is located on one side of a guide groove 21.

[0038] The main function of position sensor 14 is to detect the position of an object and convert it into a usable output signal. Position sensor 14 is existing technology and will not be described in detail here.

[0039] In a preferred embodiment, the collection components include a fixed plate 15, multiple electric grippers 16, multiple guide grooves 21, multiple discharge holes 17, and multiple collection boxes 18. The multiple guide grooves 21 are evenly distributed on the second guide plate 8, and each guide groove 21 is connected to a sliding groove 6 in a second screening component. Each discharge hole 17 is distributed on a guide groove 21. Each collection box 18 is fixed above the base plate 1 and is located directly below a discharge hole 17. The fixed plate 15 is fixed below the second guide plate 8, and each electric gripper 16 is fixed on the side of the fixed plate 15 near the sensor 14.

[0040] The electric gripper 16 is existing technology and will not be described in detail here;

[0041] The first guide plate 7 and the second guide plate 8 are respectively installed above the base plate 1 via the mounting plate 13 and the mounting rod 22. The first guide plate 7 and the second guide plate 8 have a V-shaped structure, which helps to position the screw in the middle for easy material unloading. By tilting the first guide plate 7 and the second guide plate 8, the screw between the first guide plate 7 and the second guide plate 8 moves downward. Because multiple sliding grooves 6 of different widths are opened between the first guide plate 7 and the second guide plate 8, the width of the multiple sliding grooves 6 gradually increases as they move away from the unloading hopper 11. When the screw inside the unloading hopper 11 enters the space between the first guide plate 7 and the second guide plate 8... During this process, the stud on the thinner screw first falls into the narrower sliding groove 6. Since the nut is larger, it slides between the first guide plate 7 and the second guide plate 8. When it slides to the end of the sliding groove 6, the position sensor 14 can detect the screw. Then, the position sensor 14 sends a signal to the controller, which controls the corresponding electric gripper 16 to work. The electric gripper 16 grips the screw, allowing it to move along the length of the guide groove 21. When the screw moves to the discharge hole 17, the electric gripper 16 releases the screw, causing it to fall into the collection box 18 below for collection.

[0042] Similarly, the studs on thicker screws fall into the appropriate sliding groove 6, thus completing the screening of screws with different stud diameters.

[0043] In a preferred embodiment, the mounting bracket 5 is inclined, and the inclined design allows the screws to slide above the mounting bracket 5. The mounting bracket 5 gradually decreases from left to right. Specifically, the shorter drop groove 3 is located at the higher part of the mounting bracket 5, and the longer drop groove 3 is located at the lower part of the mounting bracket 5.

[0044] In a preferred embodiment, the widths of the plurality of sliding grooves 6 between the first guide plate 7 and the second guide plate 8 increase sequentially, and the widths of the plurality of guide grooves 21 on each second guide plate 8 increase sequentially, that is, the widths of each sliding groove 6 and the guide groove 21 on one side thereon are the same.
