With a slight modification, it can also be used for the automatic assembly of cylindrical small parts. The application of the automatic screw feeding and locking machine eliminates the need to pick screws by hand, greatly improving production efficiency and saving labor. After each screw is tightened, the machine will automatically convey it to the nozzle, eliminating the need to hold the screw by hand. As long as it is directly aligned with the screw hole position, the screw can be locked with a light press, which is convenient and fast. The machine has a beautiful appearance, novel design, is small and light, and can be placed on or under the table. It is mainly applicable to the assembly processes of industries such as electronics, plastics, toys, and electrical appliances.

[0003] However, it still has some drawbacks. For example, the feeding mechanism of some automatic screw locking machines uses a turbine to scoop up screws and then rotates to drop the scooped-up screws into the feed channel for screening and sorting. However, in fact, there are usually many scraps, broken materials, and some metal powders in the screws. These small particles will fall into the gaps in the rotating mechanism. Many equipment bases are made of plastic and are easily worn. Over time, it will cause jamming and even lead to the scrapping of the machine.

[0004] To solve the above problems, a screw storage device for an automatic screw locking machine is proposed in this application. Content of the Utility Model

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a screw storage device for an automatic screw locking machine, including a main machine 1, a screw tube 2 is detachably connected to the front outer surface of the main machine 1, an electric screwdriver 3 is fixedly connected to the front outer surface of the screw tube 2, a feed bin 4 is fixedly connected to the rear outer surface of the main machine 1, a debris collection box 5 is movably connected to the outer surface of one side of the feed bin 4, a movable bin cover 6 is movably connected to the upper outer surface of the feed bin 4, and a feed hopper 7 is opened on the upper outer surface of the movable bin cover 6. The debris collection box 5 provided can automatically collect the slag, debris, metal powder, etc. that fall through the filter inside the rotatable cartridge 13. When the storage inside the debris collection box 5 reaches a certain amount, the debris collection box 5 is pulled out for cleaning, and the operation is quick and convenient.

[0022] In this embodiment, as Figure 2As shown in the figure, a supporting block 8 is fixedly connected to the inner surface of the lower end of the silo 4. An inlet piece 9 is fixedly connected to the outer surface of the rear end of the supporting block 8, and a limiting block 10 is fixedly connected to the outer surface of the rear end of the supporting block 8. By means of the provided limiting block 10, it can be ensured that the rotatable cylinder 13 always rolls between the two groups of rollers 12, avoiding falling. A rotating rod 11 is movably connected to the outer surface of the front end of the supporting block 8, and rollers 12 are fixedly connected to the outer wall of the rotating rod 11. There are two groups of rollers 12. By means of the two groups of obliquely arranged rotating rods 11 and rollers 12, the rotatable cylinder 13 can be made to roll at a certain inclination angle. In this way, not only can the screws inside the rotatable cylinder 13 be prevented from overflowing and falling from the mouth of the rotatable cylinder 13, but also it is convenient for slag, broken materials, metal powder, etc. to fall from the bottom of the rotatable cylinder 13 into the debris collection box 5. The outer walls of the two groups of rollers 12 are both movably connected to a rotatable cylinder 13. A screw arrangement and conveying device 14 is fixedly connected to the inner cavity of the main machine 1. By means of the provided rotatable cylinder 13, it can be driven to roll under the rotation of the rotating rod 11 and the rollers 12. After the rotatable cylinder 13 rolls, it can drive the internally sleeved filter barrel to roll. Metal filter meshes 18 are arranged around and at the bottom of the filter barrel. After the filter barrel rotates, the slag, broken materials and metal powder carried in the screws can be filtered through the metal filter meshes 18. The filtered slag, broken materials, metal powder, etc. will enter the inside of the rotatable cylinder 13 and reach the inlet piece 9 through the holes at the bottom. The inlet piece 9 will guide them into the debris collection box 5 for collection. In this way, slag, broken materials, metal powder, etc. can be prevented from remaining in the rotatable cylinder 13 and falling into the gaps between the machine parts, causing wear to them, and the service life of the machine can be extended.

[0023] In this embodiment, as Figures 3-4 shown, an upper filter frame 15 is movably sleeved on the inner wall of the rotatable cylinder 13. A clamping block 16 is fixedly connected to the outer wall of the upper filter frame 15. There are four groups of clamping blocks 16. The upper filter frame 15 is fixedly connected to the lower filter frame 17 through the clamping blocks 16. Metal filter meshes 18 are fixedly connected to the outer surface of the adjacent end of the upper filter frame 15 and the lower filter frame 17 and the inner cavity of the lower filter frame 17. Screw supporting pieces 19 are fixedly connected to the inner wall of the metal filter mesh 18. There are several groups of screw supporting pieces 19. Card slots 20 are formed on the inner wall of the rotatable cylinder 13. There are four groups of card slots 20. The card slots 20 are clamped with the clamping blocks 16. A cross-shaped supporting block 21 is fixedly connected to the outer surface of the lower end of the rotatable cylinder 13. By means of the clamping of the provided clamping blocks 16 and the card slots 20, it is convenient for the quick fixed connection between the filter barrel and the rotatable cylinder 13, facilitating disassembly and installation, and also convenient for taking out the filter barrel for inspection and replacement.

[0024] Working principle:

[0025] When using this product, the motor inside the lower end of the main machine 1 can be started to drive the two groups of rotation rods 11 arranged obliquely to rotate. After the rotation rods 11 rotate, they drive the rollers 12 to roll. After the rollers 12 roll, they can drive the rotatable material barrel 13 to roll. After the rotatable material barrel 13 rolls, it can drive the internally sleeved filter barrel to roll. The metal filter screen 18 is arranged around and at the bottom of the filter barrel. After the filter barrel rotates, the slag, broken materials and metal powder in the screws can be filtered through the metal filter screen 18. The filtered slag, broken materials and metal powder will enter the interior of the rotatable material barrel 13 and reach the introduction piece 9 through the holes at the bottom. The introduction piece 9 will introduce them into the debris collection box 5 for collection. In this way, it can be avoided that the slag, broken materials and metal powder continue to stay in the rotatable material barrel 13 and fall into the gaps between the machine parts, causing wear to them, and the service life of the machine can be extended. When the storage in the debris collection box 5 reaches a certain amount, the debris collection box 5 can be directly pulled out from the outside of the feed bin 4 for cleaning, which is quick and convenient to use.

[0026] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
