Description

Technical Field

[0001] This utility model belongs to the technical field of screw box structure, and in particular relates to a screw feeding device. Background Technology

[0002] Electrical control cabinets not only consist of external cabinets but also internal mounting plates for securing electrical components, cable trays, and various other electrical parts. Most of these parts require screws for secure connection. While existing screwdrivers can temporarily hold screws magnetically for quick installation and free up the operator's hands to fix parts, the operator still needs to align the screw head with the screwdriver for it to adhere properly. This prevents the operator from simultaneously handling parts and screws, impacting assembly efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a screw feeding device that can not only place screws but also arrange them for easy and quick access.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed:

[0005] A screw feeder, comprising:

[0006] The material boxes are spaced apart on the top surface of a support plate;

[0007] The lifting plate is vertically installed on the bottom plate of the material box. A strip groove is opened on the top of the lifting plate. The width of the strip groove is greater than the outer diameter of the screw shank and less than the outer diameter of the screw head. The depth of the strip groove is greater than the length of the screw shank.

[0008] The lifting plate is set to move vertically in the same direction as the material box. When the lifting plate is lowered to the lowest position, the top surface of the lifting plate is not higher than the top surface of the bottom plate of the material box. When the lifting plate is raised to the highest position, the top surface of the lifting plate is not lower than the top surface of the material box.

[0009] The beneficial effects of this utility model are as follows: By moving the lifting plate up and down, the screws in the material box can be arranged using the strip groove on the lifting plate, and the heads of the screws can be facing upwards, making it convenient for the operator to pick them up. This can effectively reduce the operator's workload, allowing the operator to use both hands to pick up screws and parts at the same time, which helps to improve assembly efficiency.

[0018] like Figure 1 , Figure 2 As shown, a screw feeding device includes: a material box 1 and a lifting plate 3.

[0019] Material boxes 1 are spaced apart on the top surface of a support plate 2, and columns are provided around the top surface of the support plate 2 to support the material boxes 1.

[0020] The lifting plate 3 is vertically mounted on the bottom plate of the material box 1. A strip groove 31 is provided on the top of the lifting plate 3. The width of the strip groove 31 is greater than the outer diameter of the screw shank and less than the outer diameter of the screw head. The depth of the strip groove 31 is greater than the length of the screw shank.

[0021] The lifting plate 3 is set to move vertically in the direction perpendicular to the material box 1. It can also be understood as the lifting plate 3 moving in the direction perpendicular to the bottom plate. Under normal conditions, the bottom plate of the material box 1 is horizontal. When the lifting plate 3 is lowered to the lowest position, the top surface of the lifting plate 3 is not higher than the top surface of the bottom plate of the material box 1, so that the screws in the material box 1 can fall into the slot 31. When the lifting plate 3 is raised to the highest position, the top surface of the lifting plate 3 is not lower than the top surface of the material box 1, so that the screws in the slot 31 protrude from the material box 1, making it easier to obtain the screws.

[0022] Before use, install the screws to at least one-third of the height of the material box 1. Before taking the screws, first move the lifting plate 3 downwards to its lowest position. The screws inside the material box 1 will automatically fall into the slot 31. Because the width of the slot 31 is smaller than the outer diameter of the screw head, the screw head will be blocked above the slot 31. However, the diameter of the screw shank is smaller than the width of the slot 31, so the screw shank will automatically fall into the slot 31, thus making the screw head face upwards. After the lifting plate 3 has descended to its lowest position, move the lifting plate 3 upwards again, and the screws falling into the slot 31 will... The screw will also rise along with the lifting plate 3 until the top of the lifting plate 3 and the head of the screw protrude from the top of the material box 1. At this time, the head of the screw is facing upwards, and the operator can hold the screwdriver and automatically suck it out from the strip groove 31. This eliminates the need for the operator to manually install the screw onto the screwdriver, which helps to reduce the operator's workload. While the operator takes out the screw, the other hand can simultaneously pick up the part to be installed, which helps to improve assembly efficiency. In addition, the strip groove 31 is a long strip structure, which can accommodate multiple screws along its length at a time, reducing the number of times the lifting plate 3 needs to be raised and lowered.

[0023] Preferred, such as Figure 1 , Figure 2 As shown, the top surface of the lifting plate 3 has two sides of the corresponding strip groove 31 with inclined surfaces. The inclined surfaces are inclined towards the outside of the lifting plate 3 to prevent screws from accumulating on the top surface of the lifting plate 3. Even if the head of some screws is stuck in the strip groove 31, but the screw part is outside the strip groove 31, the inclined surfaces can be used to prevent these screws from staying on the top surface of the lifting plate 3, and they can only fall into the material box 1 automatically along the inclined surfaces.

[0024] Preferred, such as Figure 1 , Figure 2As shown, both sides of the top opening of the slot 31 have chamfered structures, and the slope of the chamfer is consistent with the slope of the bottom surface of the screw head. This structure not only makes the screw head that falls into the slot 31 fit more closely with the opening of the slot 31, making the screw more stable when it is picked up; but also increases the contact area between the slot 31 and the screw, thereby increasing the probability of the screw falling into the slot 31.

[0025] Preferred, such as Figure 2 As shown, a support spring 4 is provided between the top surface of the support plate 2 and the bottom surface of the lifting plate 3. When the support spring 4 is in its natural state, the lifting plate 3 is in its highest position. With this design, when using screws, the operator can insert a screwdriver into the slot 31 and press the lifting plate 3 down until the top surface of the lifting plate 3 is submerged in the screw in the material box 1. Preferably, the lifting plate 3 is pressed down to its lowest position so that the top surface of the lifting plate 3 is lower than or flush with the bottom surface of the material box 1. Then, the screwdriver pressing the lifting plate 3 is released. Under the elastic force of the support spring 4, the lifting plate 3 will automatically rise to its highest position, so that the top surface of the lifting plate 3 and the head of the screw protrude from the top of the material box 1.

[0026] Preferred, such as Figure 2 As shown, the top surface of the bottom plate of the material box 1 is inclined on both sides of the lifting plate 3, and the inclined surface faces the middle of the material box 1 so that the screws are gathered in the middle of the material box 1, making it easier for the screws to move to the top of the lifting plate 3.

[0027] Preferred, such as Figure 1 As shown, the end face of the lifting plate 3 along its length is in contact with the inner wall of the material box 1. Both ends of the lifting plate 3 along its length are provided with levers 32. The side wall of the material box 1 is provided with a strip hole 11 through which the levers 32 pass. The end of the lever 32 protrudes outside the material box 1. The operator can move the lifting plate 3 up and down by moving the lever 32 downward.

[0028] Preferably, a rubber layer is provided between the bottom plate of the material box 1 for the through hole through which the lifting plate 3 passes and the outer wall of the lifting plate 3. The rubber layer is a rubber coating or a rubber ring. The rubber layer can increase the friction between the lifting plate 3 and the bottom plate of the material box 1. When the operator moves the lifting plate 3 to a predetermined height, the lifting plate 3 will not fall automatically, thus making it convenient for the operator to adjust the height position of the lifting plate 3.

[0029] Preferably, the top surface of the lifting plate 3 is provided with multiple strip grooves 31 to increase the number of arranged screws and reduce the number of times the lifting plate 3 moves.

[0030] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
