[0002] Screws are also called "screws" and "screws". In fact, screws are a general term, while screws and screw rods are different from each other. Screws are generally called; they are the kind with a pointed head at the front end, with a larger pitch, and are generally used to fasten wooden and plastic parts. Screw rods are machine screws, which are the kind with a flat head at the front end, with a smaller and uniform pitch, and are generally used to fasten metal and machine parts.

[0003] According to the prior art, the device has some shortcomings: First, when taking out the screws, a large number of screws are usually placed in a material box. When the screws are used, they are taken out from the storage chamber of the material box and then sent to the predetermined workstation. In the process of taking out the screws, at present, most of them are taken out manually or by a robot. No matter which method is used, it is impossible to quantify the screws taken out and properly control the amount of the screws taken out; Secondly, when feeding screws, they are usually transported by conveyor belt or manually. When conveying by conveyor belt, since it can only be transported horizontally, when there is a height difference between the feeding point and the feeding mechanism, the screws on the conveyor belt cannot be transported due to their own weight, so that personnel need to manually transport the screws. Thirdly, since external participation is required to take the screws out of the material box, no matter what material taking method is used, the screws in the material box will gradually decrease with use, causing the height of the screws in the material box to decrease. When the material is taken to a certain extent, the material taking device cannot perform the collection work adaptively at this time.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] First, see Figure 1 - Figure 7 As shown, the screw material taking device includes The adaptable material taking device 2 is equipped with a first servo motor 21, a transmission gear 22 is fixedly installed on the output end of the first servo motor 21, a linkage gear 23 is transmission-connected to one side of the transmission gear 22, a rotating disk 24 is fixedly installed on the other side of the linkage gear 23, a fixed disk 26 is matched with the inner wall gap of the rotating disk 24, a plurality of connection grooves 29 are opened on the rotating disk 24, and a plurality of material taking hoppers 28 are fixedly installed around the rotating disk 24; The control and adjustment device 4 is provided with a fixed plate 41, a third servo motor 42 is fixedly installed on the top of the fixed plate 41, a transmission shaft 43 is fixedly installed on the output end of the third servo motor 42, a plurality of movable arms 45 are fixedly installed around the transmission shaft 43, one end of the plurality of movable arms 45 is respectively hinged with a linkage arm 46, and the other end of the plurality of linkage arms 46 is hinged with a movable plate 47; In this embodiment, please refer to Figure 3 , Figure 6A transmission gear 22 is provided at the output end of the first servo motor 21. When driven, the transmission gear 22 rotates clockwise. The transmission gear 22 meshes with the linkage gear 23. The back side of the linkage gear 23 is fixed to the turntable 24. There is a gap between the inner wall of the turntable 24 and the fixed disk 26 to provide movement, and this gap is smaller than the size of the screw. When the turntable 24 opens the connecting groove 29, the screw for taking the material from the hopper 28 directly contacts the fixed disk 26 through the connecting groove 29. When the turntable 24 rotates clockwise, the screw is limited under the installation of the hopper 28. In this embodiment, the third A transmission shaft 43 is provided at the output end of the servo motor 42. The transmission shaft 43 passes through a plurality of movable arms 45 and fixes them. When the third servo motor 42 provides power, the transmission shaft 43 rotates. Under the rotation of the transmission shaft 43, the movable arms 45 move in a circle around the transmission shaft 43. The other ends of the plurality of movable arms 45 are respectively hinged to linkage arms 46. Under the action of the pulling force of the movable arms 45, the linkage arms 46 move in a circle around the hinges of the movable arms 45. The other ends of the plurality of linkage arms 46 are hinged to the bottom of the movable plate 47. By controlling the rotation of the transmission shaft 43, the distance between the fixed plate 41 and the movable plate 47 can be adjusted.

[0021] Furthermore, a drop groove 27 is provided on one side of the fixed plate 26, and two supporting wheels 25 are movably mounted on one side of the fixed plate 26, and one side of the two supporting wheels 25 is movably mounted on the inner wall of the rotating plate 24; In this embodiment, please refer to Figure 3 , Figure 5 , through the opening of the falling groove 27 by the fixed plate 26, when the turntable 24 rotates clockwise, the multiple connecting grooves 29 and the hopper 28 drive the screws to be transported on the fixed plate 26, and the feeding work of the screws is completed. When the connecting groove 29 coincides with the falling groove 27 opened on the fixed plate 26, the screws that are not limited by the outer wall of the fixed plate 26 fall through the falling groove 27 under their own weight. When the turntable 24 moves on the outer wall of the fixed plate 26, in order to prevent the inner wall of the turntable 24 and the outer wall of the fixed plate 26 from causing friction and wear, a plurality of supporting wheels 25 are provided to support the inner wall of the turntable 24, and reverse on the fixed plate 26 when the turntable 24 rotates, so that the turntable 24 has corresponding stability when it rotates, and at the same time, the wear of the fixed plate 26 when the turntable 24 rotates is avoided.

[0022] Furthermore, four universal wheels 401 with self-locking function are fixedly installed at the bottom of the fixed plate 41, and two fixed bearings 44 are fixedly installed at the top of the fixed plate 41. The transmission shaft 43 is movably installed through the two fixed bearings 44; In this embodiment, please refer to Figure 6Four universal wheels 401 are provided at the bottom of the fixed plate 41, and the universal wheels 401 have a self-locking function. When the screws in the material box 402 are consumed excessively, personnel move the control adjustment device 4 and provide assistance for the overall movement under the setting of the universal wheels 401. Screws are added to the inside of the material box 402. A fixed bearing 44 is provided on the fixed plate 41. When the transmission shaft 43 is installed, the transmission shaft 43 is supported and limited accordingly, so that it always rotates at the same position, thereby ensuring the smooth lifting and lowering of the movable plate 47.

[0023] Furthermore, four limiting rods 48 are fixedly installed on the top of the fixed plate 41, and the limiting rods 48 respectively penetrate and movably install limiting sleeves 49, and the four limiting sleeves 49 are fixedly installed with movable plates 47, and a material box 402 is placed on the top of the movable plate 47; In this embodiment, please refer to Figure 6 The movable plate 47 is driven to move up and down through the linkage arm 46.

Limit sleeves 49 are respectively installed on the outer walls of the limit rods 48. When the movable plate 47 is moving, it slides on the limit rods 48 through the limit sleeves 49. The four limit sleeves 49 cooperate with the limit rods 48 to limit the four sides of the movable plate 47, so that the movable plate 47 can always be lifted and lowered horizontally.

[0024] Second, see Figure 1 - Figure 7 As shown, the screw feeding device comprises The screw taking device mentioned above; The collecting and feeding component 3 is provided with a collecting bucket 38, which is arranged directly below the connecting seat 37. A conveying channel 32 is fixedly installed at the bottom of the collecting bucket 38, a delivery bin 39 is fixedly installed on one side of the delivery channel 32, a second servo motor 33 is fixedly installed on the other side of the delivery bin 39, an auger 34 is fixedly installed on the output end of the second servo motor 33, the auger 34 is transitionally matched with the inner wall of the delivery channel 32 around the periphery, and one end of the auger 34 is movably installed with the delivery channel 32; A main body 1 is provided with a support rod 11, and a working platform 12 is fixedly installed on the top of the support rod 11; In this embodiment, please refer to Figure 4 , Figure 5 The inner cavity of the conveying channel 32 is provided with an auger 34, one end of the auger 34 is movably installed with the conveying channel 32, and the conveying channel 32 and the auger 34 are mutually coordinated to convey the screws, so that the screws are conveyed to the inner cavity of the delivery bin 39, and the second servo motor 33 is fixed on the other side of the delivery bin 39, so that the second servo motor 33 generates power to drive the auger 34 to rotate.

[0025] Furthermore, a connecting seat 37 is fixedly installed around the conveying channel 32, and the connecting seat 37 is fixedly installed on the inner wall of the fixed plate 26. A connecting frame 36 is fixedly installed on the top of the conveying channel 32, and a first servo motor 21 is fixedly installed on the top of the connecting frame 36. In this embodiment, please refer to Figure 4 , Figure 5 The connecting seat 37 is installed through the conveying channel 32, and the connecting seat 37 supports the fixed plate 26 to ensure its support. At the same time, a drop groove 27 is provided just above the collecting bucket 38, so that the screws conveyed by the drop groove 27 can enter the inner cavity of the conveying channel 32 through the collecting bucket 38. The first servo motor 21 is fixed by the connecting frame 36 to ensure that the transmission gear 22 and the linkage gear 23 are always meshed, which is conducive to the stability of the mutual transmission between the transmission gear 22 and the linkage gear 23.

[0026] Furthermore, three support frames 31 are fixedly installed at the bottom of the conveying channel 32, and a cover plate 35 is movably installed at the top of the delivery bin 39; In this embodiment, please refer to Figure 4 , Figure 5 With the cover plate 35 installed, personnel can open and close it, which is convenient for personnel to observe the conveyed screws, so that the overall feeding work can be carried out well. The working platform 12 is supported by the support rod 11 to ensure stable operation of the top.

[0027] Furthermore, a vibrating screen 13 is fixedly mounted on the top of the support rod 11, and the vibrating screen 13 is arranged directly below the delivery bin 39; In this embodiment, please refer to Figure 4 , Figure 7 By setting the vibrating screen 13 directly below the delivery bin 39, the screws are delivered to the delivery bin 39 through the mutual coordination between the conveying channel 32 and the auger 34, and the delivery bin 39 delivers the delivered screws to the top of the vibrating screen 13, so that the delivered screws can be directly delivered for use.

[0028] Working principle: Step 1, by driving the first servo motor 21, the transmission gear 22 at the output end rotates. The transmission gear 22 cooperates with the linkage gear 23 during work. A turntable 24 is fixedly installed on one side of the linkage gear 23, and the turntable 24 is driven by the linkage gear 23 to rotate around the fixed disk 26. During the rotation, the turntable 24 takes the screws inside the material box 402 through the hopper 28. The screws will contact the outer wall of the fixed disk 26 through the connecting groove 29 inside the hopper 28, so as to limit the screws accordingly. When one of the multiple connecting grooves 29 moves to coincide with the falling groove 27, the screws are not constrained by the fixed disk 26 at this time, and fall from the falling groove 27 to the collecting bucket 38 for feeding. When feeding, the first servo motor 21 is controlled, so as to adjust the rotation speed of the turntable 24 accordingly through the transmission gear 22, make adaptive quantitative adjustment for the material taking of the screws, and complete the material taking of the screws.

[0029] Step 2, the screws discharged through the drop chute 27 are received by the collecting bucket 38, so that the screws pass through the collecting bucket 38 and enter the inner cavity of the conveying channel 32. At this time, the second servo motor 33 is driven to rotate the auger 34. Since the four sides of the auger 34 are in transition with the inner cavity of the conveying channel 32, the rotating auger 34 pushes the screws for conveying. When the screws are conveyed to the position of the delivery bin 39, the screws fall from the delivery bin 39 to the inside of the vibrating screen 13 for use.

[0030] Step three, when the material picking device 2 is adapted to pick up the screws, as the screws are transported, the height of the screws stored in the material box 402 will change until the material picking hopper 28 cannot pick up the screws in time. When the height of the screws changes, the third servo motor 42 is driven to rotate the transmission shaft 43 at the output end. At this time, the movable arm 45 fixed on the transmission shaft 43 will perform circular motion with the transmission shaft 43 as the axis, and one end of the transmission shaft 43 will be linked to the linkage arm 46. The other end of the linkage arm 46 is hinged to the bottom of the movable plate 47. As the movable distance of the movable arm 45 is controlled, the linkage arm 46 drives the movable plate 47 to perform corresponding movable lifting, and the height of the material box 402 placed on the top of the movable plate 47 is adjusted, and the lifting and lowering of the material picking hopper 28 is adaptively adjusted.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
