[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0025] Embodiment 1:

[0026] See also Figure 1 - Figure 6 A screw feeding device for screw processing comprises a fixed base plate 1, a first electric slide rail 6 is fixedly connected to the top of the fixed base plate 1, the first electric slide rail 6 is slidably connected to a sliding plate 7 through an electronic slider, a second electric slide rail 8 is fixedly connected to the top of the sliding plate 7, the second electric slide rail 8 is slidably connected to a fixed vertical rod 12 through an electronic slider, a limited soft ring 13 is fixedly connected to the top of the fixed vertical rod 12, a side wall of the limited soft ring 13 is fixedly connected to an annular slide rail 14, the annular slide rail 14 is slidably connected to a cleaning arc brush 15 through an electronic slider, a pushing mechanism is fixedly connected to the top of the sliding plate 7, a feeding mechanism is fixedly connected to the side wall of the fixed base plate 1, and the first The second electric slide rail 8 is slidably connected to the second electric push rod 16 through an electronic slider, the top of the second electric push rod 16 is fixedly connected to a clamping bin 17, one side of the clamping bin 17 is fixedly connected to a driving motor 18, the output end of the driving motor 18 is fixedly connected to a rotating bin 19, the inner wall of the rotating bin 19 is fixedly connected to a fourth electric push rod 22, the bottom of the fourth electric push rod 22 is fixedly connected to a clamping arc plate 23, the top of the fixed bottom plate 1 is fixedly connected to a fixed transverse plate 24, one side of the fixed transverse plate 24 is fixedly connected to a cleaning mechanism, one side of the fixed transverse plate 24 is fixedly connected to a sixth electric push rod 27, and one end of the sixth electric push rod 27 is fixedly connected to a laser level 28.

[0027] It should be noted that the staff puts the screw to be processed inside the lower bin 5, and the screw inside the lower bin 5 falls into the limit soft ring 13 under the action of gravity, and starts the first electric push rod 10. The first electric push rod 10 pushes the screw into the rotating bin 19 through the first push plate 11 and the fixed vertical rod 12. When the screw is pushed into the rotating bin 19, the fourth electric push rod 22 is started, and the fourth electric push rod 22 drives the clamping arc plate 23 to move to the surface of the screw to clamp and fix it. Screws of different specifications can be clamped and conveyed. Through the setting of the second electric slide rail 8, the two fixed vertical rods 12 and the two limit soft rings 13, the distance between the two limit soft rings 13 can be adjusted to adapt to the clamping of screws of different models, thereby expanding the working range of the device;

[0028] The drive motor 18 is started, and the drive motor 18 drives the screw to rotate through the rotating bin 19, the fourth electric push rod 22 and the clamping arc plate 23, and the first electric slide rail 6 is started, and the first electric slide rail 6 drives the screw to move through the sliding plate 7, the second electric slide rail 8, the second electric push rod 16, the clamping bin 17, the rotating bin 19, the fourth electric push rod 22 and the clamping arc plate 23. When the screw is moving, the sixth electric push rod 27 is driven, and the sixth electric push rod 27 drives the laser level 28 to move close to the screw, and the laser level 28 is started. The laser level 28 performs an all-round flatness detection on the surface of the rotating screw to prevent the screw from being knocked during transportation of the fixed base plate 1. When the screw is damaged, when the screw flatness detection is completed and it is confirmed that the screw is intact, start the second electric push rod 16, the second electric push rod 16 drives the screw to rise to the milling machine through the clamping bin 17, the rotating bin 19, the fourth electric push rod 22 and the clamping arc plate 23, the fourth electric push rod 22 drives the clamping arc plate 23 away from the screw to stop clamping and limit it, and at the same time, start the third electric push rod 20, the third electric push rod 20 drives the screw into the milling machine through the second push plate 21, completes the full-automatic loading, improves the automation degree of the device, the screw inside the rotating bin 19 is not detected by the laser level 28, and can be cut and removed when the milling machine screw is processed;

[0029] After the screw is conveyed to the milling machine, the annular slide rail 14 is started, and the annular slide rail 14 drives the cleaning arc brush 15 to brush the inner wall of the limiting soft ring 13 to prevent the limiting soft ring 13 from being contaminated by impurities and scratching the subsequent screw surface.

[0030] In an optional embodiment: the side wall of the fixed bottom plate 1 is fixedly connected to a limiting horizontal plate 32, the top of the limiting horizontal plate 32 is fixedly connected to a third electric slide rail 33, the third electric slide rail 33 is slidably connected to a storage bin 34 through an electronic slider, the inner wall of the storage bin 34 is fixedly connected to a fixed round rod 35, the side wall of the fixed round rod 35 is movably connected to a clamping frame 36, the inner wall of the storage bin 34 is fixedly connected to a limiting plate 39, the inner wall of the storage bin 34 is fixedly connected to a limiting spring 31, and the inner wall of the storage bin 34 is fixedly connected to a shock absorbing mechanism.

[0031] It should be noted that when the side wall of the screw is damaged by collision at the detection location of the laser level 28, the first electric slide rail 6 drives the screw to move to the side of the storage bin 34, the fourth electric push rod 22 drives the clamping arc plate 23 to reset, and the third electric push rod 20 pushes the screw into the clamping frame 36 through the second push plate 21. As the screw enters the clamping frame 36, the overall mass of the clamping frame 36 increases sharply. The clamping frame 36 squeezes the top of the limit plate 39 under the action of gravity, and the limit spring 31 inside the limit plate 39 contracts and stops limiting the clamping frame 36. The clamping frame 36 falls to the bottom of the storage bin 34 with the internal screw, and repeats this process. This avoids the subsequent discovery of other damaged screws that directly collide with each other during storage, causing secondary damage and increasing the difficulty of subsequent maintenance by the staff.

[0032] In an optional embodiment: the unloading mechanism includes a fixed vertical plate 4, the side wall of the fixed bottom plate 1 is fixedly connected to the side wall of the fixed vertical plate 4, and a unloading bin 5 is fixedly connected to one side of the fixed vertical plate 4.

[0033] It should be noted that the unprocessed screws can be initially stored and discharged through the cooperation between the fixed vertical plate 4 and the discharge bin 5 .

[0034] In an optional embodiment: the pushing mechanism includes a sliding vertical plate 9, the bottom of the sliding vertical plate 9 is fixedly connected to the top of the sliding plate 7, a first electric push rod 10 is fixedly connected to one side of the sliding vertical plate 9, one end of the first electric push rod 10 is fixedly connected to the first push plate 11, a third electric push rod 20 is fixedly connected to the inner wall of the rotating bin 19, and one end of the third electric push rod 20 is fixedly connected to the second push plate 21.

[0035] It should be noted that the screw can be pushed into the rotating bin 19 through the cooperation of the first electric push rod 10 and the first push plate 11, and the screw can be pushed out of the rotating bin 19 through the cooperation of the third electric push rod 20 and the second push plate 21. The staff does not need to manually adjust the screw position, further reducing the workload of the staff.

[0036] In an optional embodiment: the cleaning mechanism includes a fifth electric push rod 25 , one end of the fifth electric push rod 25 is fixedly connected to the fixed bottom plate 1 and one side of the fixed cross plate 24 , and one end of the fifth electric push rod 25 is fixedly connected to a cleaning brush 26 .

[0037] It should be noted that when the sliding plate 7 drives the screw to move, the fifth electric push rod 25 is started, and the fifth electric push rod 25 drives the cleaning brush 26 to move to the surface of the screw to brush it, so as to avoid impurities adhering to the side wall of the screw affecting the subsequent laser level 28 to detect the flatness of the screw surface.

[0038] In an optional embodiment: a lubricating oil tank 29 is fixedly connected to one side of the fixed transverse plate 24 , and an electric telescopic tube 30 is connected to one side of the lubricating oil tank 29 .

[0039] It should be noted that when the sliding plate 7 drives the screw to move, the electric telescopic tube 30 is started, the electric telescopic tube 30 moves to the side wall of the screw, and the water pump inside the lubricating oil tank 29 is started to spray the lubricating oil inside the lubricating oil tank 29 onto the surface of the screw to lubricate it, which can effectively reduce the wear of the screw.

[0040] In an optional embodiment: the shock-absorbing mechanism includes a shock-absorbing spring 38, the bottom of the shock-absorbing spring 38 is fixedly connected to the bottom of the inner wall of the storage bin 34, the bottom of the inner wall of the storage bin 34 is fixedly connected to a shock-absorbing plate 37, and the bottom of the inner wall of the shock-absorbing plate 37 is fixedly connected to the top of the shock-absorbing spring 38.

[0041] It should be noted that the cooperation between the shock-absorbing spring 38 and the shock-absorbing plate 37 can reduce shock when the clamping frame 36 drives the screw rod to fall, thereby preventing the clamping frame 36 from being directly installed on the inner wall of the storage bin 34 and being damaged.

[0042] In an optional embodiment: an empty slot 2 is opened inside the fixed bottom plate 1, and a garbage storage box 3 is fixedly connected to the bottom of the fixed bottom plate 1.

[0043] It should be noted that the garbage cleaned by the fixed round rod 35 can be collected and stored through the cooperation between the empty slot 2 and the garbage storage box 3.

[0044] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0045] During operation, the staff puts the screw rod to be processed inside the lower bin 5, and the screw rod inside the lower bin 5 falls into the limit soft ring 13 under the action of gravity, and starts the first electric push rod 10. The first electric push rod 10 pushes the screw rod into the rotating bin 19 through the first push plate 11 and the fixed vertical rod 12. When the screw rod is pushed into the rotating bin 19, the fourth electric push rod 22 is started, and the fourth electric push rod 22 drives the clamping arc plate 23 to move to the surface of the screw rod to clamp and fix it. Screw rods of different specifications can be clamped and conveyed. Through the setting of the second electric slide rail 8, the two fixed vertical rods 12 and the two limit soft rings 13, the distance between the two limit soft rings 13 can be adjusted to adapt to the clamping of screw rods of different models, thereby expanding the working range of the device.

[0046] The drive motor 18 is started, and the drive motor 18 drives the screw to rotate through the rotating bin 19, the fourth electric push rod 22 and the clamping arc plate 23, and the first electric slide rail 6 is started, and the first electric slide rail 6 drives the screw to move through the sliding plate 7, the second electric slide rail 8, the second electric push rod 16, the clamping bin 17, the rotating bin 19, the fourth electric push rod 22 and the clamping arc plate 23. When the screw is moving, the sixth electric push rod 27 is driven, and the sixth electric push rod 27 drives the laser level 28 to move close to the screw, and the laser level 28 is started. The laser level 28 performs an all-round flatness detection on the surface of the rotating screw to prevent the screw from being knocked during transportation of the fixed base plate 1. When the screw is damaged, when the screw flatness detection is completed and it is confirmed that the screw is intact, start the second electric push rod 16, the second electric push rod 16 drives the screw to rise to the milling machine through the clamping bin 17, the rotating bin 19, the fourth electric push rod 22 and the clamping arc plate 23, the fourth electric push rod 22 drives the clamping arc plate 23 away from the screw to stop clamping and limit it, and at the same time, start the third electric push rod 20, the third electric push rod 20 drives the screw into the milling machine through the second push plate 21, completes the full-automatic loading, improves the automation degree of the device, the screw inside the rotating bin 19 is not detected by the laser level 28, and can be cut and removed when the milling machine screw is processed;
