Description

Technical Field

[0001] This utility model relates to the field of screw straightening technology, specifically a straightening mechanism for combined screw feeding. Background Technology

[0002] As a core fastener in fields such as machinery manufacturing and electronic assembly, screws directly affect product production cycle time, assembly quality, and manufacturing costs due to their assembly efficiency and precision. With the upgrading of automated production lines towards higher speeds, greater precision, and unmanned operation, screw feeders have become key supporting equipment in automated assembly lines. However, the "disordered posture" problem in their traditional feeding mode is gradually becoming a core bottleneck restricting production efficiency.

[0003] Combination screws refer to screws that combine a screw, spring washer, and flat washer. Normal screw feeding uses a suspended nut method, allowing the screw to hang freely and vertically. Because the spring washer is an uneven washer, the screw is tilted while suspended. Traditional rotary screw feeders encounter this tilting phenomenon when feeding combination screws (such as those combining three components), which affects manual / machine unloading. Furthermore, manual unloading may introduce foreign object contamination or damage risks. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a straightening mechanism for combined screw feeding, including an I-beam plate, a fixing column mounted on the top of the I-beam plate, a disc device plate mounted on the top of the fixing column, a disc hole in the middle of the disc device plate, a disc located at the disc hole, a rotating shaft mounted in the middle of the disc, a clamping piece mounted on the lower end of the disc device plate, a washer mounted between the disc device plate and the clamping piece, the washer passing through a straightening stop, the straightening stop located between the disc device plate and the clamping piece, an armature mounted on the other side of the straightening stop, the armature corresponding to an electromagnet, an electromagnet mounting plate mounted on one side of the I-beam plate, an electromagnet and a stud mounted on the electromagnet mounting plate, a tension spring mounted between the stud and the straightening stop, and infrared sensors mounted on both sides of the disc.

[0007] Furthermore, the I-beam includes a top plate, side plates, and a bottom plate. The rotating shaft passes through the top plate and the bottom plate. An infrared mounting plate is installed on the side plate, and an infrared sensor transmitter and receiver are respectively installed on the top two sides of the infrared mounting plate.

[0008] Furthermore, a lower disc is mounted on the rotating shaft. The lower disc is located at the lower end of the main disc. Both the main disc and the lower disc have several slots for placing straightening screws along their edges. One end of the straightening stop is located between the main disc and the lower disc.

[0009] Furthermore, the straightening stop includes a straightening plate, a rotating plate, a pulling plate, and an armature mounting plate connected in sequence. The straightening plate and the rotating plate are both horizontally set, the armature mounting plate is vertically set, the pulling plate is provided with a tension spring mounting hole, and the rotating plate is fitted onto the washer.

[0010] Furthermore, the end of the straightening plate has an arc-shaped structure, and the side of the straightening plate facing the disc has protrusions.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] As shown in the figure, this utility model discloses a straightening mechanism for combined screw feeding, including an I-beam plate 1, a fixing post 2 installed on the top of the I-beam plate 1, a disc device plate 3 installed on the top of the fixing post 2, a disc hole provided in the middle of the disc device plate 3, a disc 4 located at the disc hole, a rotating shaft 5 installed in the middle of the disc 4, a clamping piece 6 installed at the lower end of the disc device plate 3, a washer 7 installed between the disc device plate 3 and the clamping piece 6, the washer 7 passing through a straightening stop 8, the straightening stop 8 located between the disc device plate 3 and the clamping piece 6, an armature 9 installed on the other side of the straightening stop 8, the armature 9 corresponding to an electromagnet 10, an electromagnet mounting plate 11 installed on one side of the I-beam plate 1, an electromagnet 10 and a stud 12 installed at the electromagnet mounting plate 11, a tension spring 13 installed between the stud 12 and the straightening stop 8, and infrared sensors installed on both sides of the disc 4.

[0028] Screw 23 is on disc 4 and rotates with the disc. When it moves to the position of the straightening stop 8, the infrared sensor detects screw 23. At this time, electromagnet 10 is not energized, and tension spring 13 pulls the straightening stop 8. The straightening stop 8 squeezes screw 23, and screw 23 is upright in this position.

[0029] When the infrared sensor detects screw 23, the electric screwdriver (not shown in the figure, located above the entire straightening mechanism) moves downwards to remove screw 23. During the downward movement of the electric screwdriver, another infrared sensor detects the electric screwdriver. At this time, the electromagnet 10 is energized (the energization can be delayed). The electromagnet 10 is magnetic and attracts the armature 9 at this location. The armature 9 drives the straightening stop 8 to rotate, releasing screw 23. The straightening stop 8 no longer presses the screw 23, and the electric screwdriver removes screw 23. Then, the electromagnet 10 is de-energized, and the straightening stop 8 rotates in the opposite direction to reset, continuing to press the next screw 23.

[0030] In one embodiment of this utility model, the I-beam plate 1 includes a top plate 101, a side plate 102, and a bottom plate 103. A rotating shaft 5 passes through the top plate 101 and the bottom plate 103. An infrared mounting plate 14 is installed on the side plate 102, and infrared sensor transmitters 15 and receivers 16 are respectively installed on the top two sides of the infrared mounting plate 14. This utility model is equipped with two infrared sensors: one for sensing screws and the other for sensing electric screwdrivers.

[0031] In one embodiment of this utility model, a lower disc 17 is mounted on the rotating shaft 5. The lower disc 17 is located at the lower end of the disc 4. Both the disc 4 and the lower disc 17 have several straightening screw placement slots 401 on their edges. One end of the straightening stop 8 is located between the disc 4 and the lower disc 17.

[0032] This invention adds a lower disc 17, so that one side of the screw 23 is blocked by the disc 4 and the lower disc 17, and the other side is blocked by the straightening stop 8. Moreover, the straightening stop 8 is located between the disc 4 and the lower disc 17, ensuring that the screw 23 is straightened and will not shift.

[0033] In one embodiment of this utility model, the straightening stop 8 includes a straightening plate 81, a rotating plate 82, a pulling plate 83 and an armature mounting plate 84 connected in sequence. The straightening plate 81 and the rotating plate 82 are both horizontally arranged, the armature mounting plate 84 is vertically arranged, the pulling plate 83 is provided with a tension spring mounting hole 831, and the rotating plate 82 is fitted on the washer 7.

[0034] The straightening plate 81 is used to straighten and block the screw 23. The rotating plate 82 rotates around the washer 7, which in turn drives the straightening plate 81, the pulling plate 83 and the armature mounting plate 84 to rotate.

[0035] In one embodiment of this utility model, the end of the straightening plate 81 is an arc-shaped structure, and the side of the straightening plate 81 facing the disc 4 is provided with a protrusion 811. When the screw 23 is pressed, the protrusion 811 of the straightening plate 81 contacts the screw 23.

[0036] In one embodiment of this utility model, a gear fixing seat 18 is installed at the side plate 102, a gear set 19 and a gear dial 20 are installed at the gear fixing seat 18, a motor 21 is installed at the lower end of the gear fixing seat 18, the output end of the motor 21 is connected to the gear set 19, the gear set 19 meshes with the gear dial 20, and the gear dial 20 is connected to the cross drive block 22 installed on the rotating shaft 5.

[0037] When motor 21 operates, it drives the gears of gear set 19 to rotate. Gear set 19 drives gear dial 20 to rotate, which in turn drives cross drive block 22 to rotate, thereby driving rotating shaft 5 to rotate. Of course, other transmission mechanisms can also be used to drive rotating shaft 5 using motor 21. The above is a conventional solution in the industry and will not be described in detail here. The above structure does not belong to the straightening mechanism.

[0038] In one embodiment of this utility model, the electromagnet mounting plate 11 includes a horizontal plate 111 and a vertical plate 112. The horizontal plate 111 is installed at the lower end of the top plate 101, the stud 12 is installed on the horizontal plate 111, and the electromagnet 10 is installed on the vertical plate 112. The design of the vertical plate 112 makes the axis of the electromagnet 10 horizontally set, which facilitates the electromagnet 10 to attract the armature.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
