Thus, a feature defined as "first", "second", "third", and "fourth" may explicitly or implicitly include one or more of the feature. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0038] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] like Figure 1-Figure 9 As shown, an embodiment of the present invention provides an automatic screw-in machine, comprising a feeding component 1 for supplying screws 800, a feeding mechanism 2 for transferring the screws 800 supplied by the feeding component 1 to a processing position, a discharging mechanism 4 for placing a wiring frame 900 into which the screws 800 are to be screwed, a loading mechanism 5 for supplying the wiring frame 900 to the discharging mechanism 4, and a screw-in component 3 for screwing the screws 800 on the feeding mechanism 2 into the wiring frame 900 on the discharging mechanism 4; the screw-in component 3 comprises a screw-in mounting plate 31, a screw-in lifting plate 32 slidably connected to the screw-in mounting plate 31, A screw-in lifting drive mechanism 33 for driving the screw-in lifting plate 32 to slide, a screw-in drive motor 34 arranged on the screw-in lifting plate 32, a screw-in bit 35 arranged on the output shaft of the screw-in drive motor 34 and used to tighten the screw 800, a screw-in position sensor 36 (which can be a Hall sensor) arranged on the screw-in mounting plate 31, and a screw-in trigger piece 37 arranged on the screw-in lifting plate 32 and cooperating with the screw-in position sensor 36; the feeding mechanism 5 includes a feeding vibration plate 51, a feeding pipe 52 arranged at the outlet of the feeding vibration plate 51, and a feeding vibrator 53 arranged on the feeding pipe 52.

[0040] In an embodiment of the present invention, the working process of the automatic screw-in machine is as follows: the feeding component 1 is used to process the scattered screws 800 into a state that is convenient for screwing into the wiring frame 900 (the head is above the rod), and the feeding vibration plate 51 of the feeding mechanism 5 transports the scattered wiring frame 900 to the corresponding processing position of the discharging mechanism 4 through the feeding pipe 52. The screws 800 processed by the feeding component 1 enter the feeding mechanism 2 and are transported by the feeding mechanism 2 to the top of the wiring frame 900 of the discharging mechanism 4, and then the screwing-in component 3 screws the screws 800 into the wiring frame 900 to complete the processing, thereby realizing the automation of screwing in the screws 800.

[0041] The working process of the screwing component 3 is as follows: the screwing-in lifting drive mechanism 33 drives the screwing-in lifting plate 32 to move downward, and the screwing-in drive motor 34 drives the screwing bit 35 to screw in the screw 800. When the screwing-in trigger piece 37 on the screwing-in lifting plate 32 triggers the screwing-in position sensor 36, the screwing-in drive motor 34 stops rotating (the screwing-in lifting drive mechanism 33 no longer drives the screwing-in lifting plate 32 to move downward), thereby achieving the screwing of the screw 800 into the preset depth, thereby improving the tightening efficiency of the screw 800.

[0042] The process of the feeding mechanism 5 conveying the wiring frame 900 to the discharging mechanism 4 is as follows: the feeding vibration plate 51 vibrates and rotates the messy wiring frame 900 to enter the feeding pipe 52 from its own outlet, and the feeding vibrator 53 vibrates to convey the wiring frame 900 in the feeding pipe 52 to the processing position on the discharging mechanism 4 for subsequent screwing processing.

[0043] For further information, see Figure 8-Figure 9As a specific embodiment of the automatic screw-in machine provided by the present invention, the feeding assembly 1 includes a screw material box 11, a feeding lifting plate 12 arranged on the screw material box 11, a feeding lifting drive mechanism 13 for driving the feeding lifting plate 12 to move, a feeding track 14 matched with the feeding lifting plate 12, and a feeding vibrator 15 arranged on the feeding track 14; the top of the feeding lifting plate 12 has a feeding inclined surface 121 inclined away from the feeding track 14, and the feeding lifting plate 12 is provided with a feeding groove 122 on the feeding inclined surface 121 that is communicated with the feeding track 14. The working process of the feeding assembly 1 is as follows: a sufficient amount of screws 800 are placed in the screw material box 11, and the feeding lifting drive mechanism 13 drives the feeding lifting plate 12 to move up and down at a preset frequency. When the feeding lifting plate 12 moves to the lowest point, it is close to the bottom of the screw material box 11 and is covered by the screws 800. Then, during the upward movement of the feeding lifting plate 12, some of the screws 800 fall into the feeding groove 122 of the feeding lifting plate 12 (the head of the screw 800 is hung on the notch of the feeding groove 122, and the rest of the part is located in the feeding groove 122, and the head of the screw 800 is located on the upper part of the rod. The square state is convenient for the subsequent tightening of the screw 800), the feed trough 122 is opened on the feed slope 121, and the feed slope 121 is inclined in the direction away from the feed track 14. Therefore, the screw 800 in the feed trough 122 slides along the feed trough 122 to the feed track 14 due to its own weight, and the feed vibrator 15 works to vibrate the screw 800 in the feed track 14 to the output port of the feed track 14, thereby completing the automatic feeding of the screw 800. Compared with the method of manually placing the screw 800 into the feed track 14, the processing efficiency is effectively improved.

[0044] For further information, see Figure 8-Figure 9 As a specific embodiment of the automatic screw-in machine provided by the present invention, an obstacle-clearing motor 16 is provided on the screw material box 11, and an obstacle-clearing block 161 (which can be a brush) is provided on the output shaft of the obstacle-clearing motor 16, and the obstacle-clearing motor 16 is located directly above the feeding track 14; a feeding mounting plate 17 is provided on the feeding track 14, and a full material sensor 18 for detecting the screws 800 on the feeding track 14 is provided on the feeding mounting plate 17; the feeding track 14 includes two feeding guide plates 141 that are opposite and spaced apart.

[0045] When the head of the screw 800 is hung on the notch of the feed trough 122 and the rest of the part is located in the feed trough 122, the screw 800 slides along the feed trough 122 into the feed track 14 and moves along the feed track 14; part of the length of the feed track 14 is located inside the screw box 11. If the screw 800 in the screw box 11 hits the feed track 14 due to the movement of the feed lifting plate 12 instead of sliding into the feed track 14 from the feed trough 122, at this time, due to the irregular shape of the screw 800, it may not be able to move along the feed track 14, thereby affecting the movement of other screws 800 on the feed track 14; a clearing motor 16 is provided to drive the clearing block 161 to rotate, so as to clear the screws 800 that are on the feed track 14 instead of moving along the track groove on the feed track 14, so as to avoid affecting the normal movement of other screws 800 along the feed track 14.

[0046] During the processing, when the feed track 14 is full of screws 800, the feed lifting plate 12 continues to rise and fall and cannot add screws 800 to the feed track 14. A full material sensor 18 is provided to detect whether the feed track 14 is full of screws 800. Specifically, the full material sensor 18 counts the number of screws 800 passing through. If the number meets the maximum value that the feed track 14 can bear, the feed lifting drive mechanism 13 stops working and no longer drives the feed lifting plate 12 to perform lifting and lowering movements.

[0047] When the screw 800 moves on the feeding track 14 , the head of the screw 800 is hung on the feeding guide plate 141 , and the remaining part is located in the feeding guide groove formed by the gap between the feeding guide plates 141 , and moves in the feeding track 14 with the vibration of the feeding vibrator 15 .

[0048] A feeding sensor can be synchronously arranged on the feeding pipe 52 of the feeding mechanism 5 to detect whether the number of wiring frames 900 in the feeding pipe 52 meets the preset requirements. When the full-material sensor 18 and the feeding track 14 are full of screws 800 and the feeding sensor detects that the number of wiring frames 900 in the feeding pipe 52 meets the preset requirements; the feeding mechanism 2 starts working to transport the screws 800 in sequence to the bottom of the screwdriver bit 35, that is, the top of the wiring frame 900, and screws the screws 800 into the wiring frame 900 by screwing into the component 3.

[0049] For further information, see Figure 5-Figure 6As a specific embodiment of the automatic screw-in machine provided by the present invention, the feeding mechanism 2 includes a feeding base plate 21, a feeding guide plate 22 arranged on the feeding base plate 21 and provided with a feeding guide groove 221, a feeding push plate 23 arranged in the feeding guide groove 221 and slidably connected to the feeding guide plate 22, and a feeding driving device 24 for driving the feeding push plate 23 to move; the feeding push plate 23 is provided with a feeding receiving groove 231 for receiving the screw 800 on the feeding track 14, the feeding guide plate 22 is provided with a first feeding clearance hole 222 at the bottom of the feeding guide groove 221, and the feeding base plate 21 is provided with a second feeding clearance hole 211 corresponding to the first feeding clearance hole 222.

[0050] When the screw 800 moves to the exit of the feed track 14 and is about to detach from the feed track 14, in order to ensure that the equipment for tightening the screw 800 can better screw the screw 800 into the wiring frame 900, a feeding mechanism 2 is provided to feed the screw 800 to the processing position. The specific process is as follows: after the screw 800 detaches from the feed track 14, it enters the feeding receiving slot 231 on the feeding push plate 23, and the feeding drive device 24 drives the feeding push plate 23 to move and drives the screw 800 to move. When the screw 800 moves to the top of the first feeding clearance hole 222, it falls from the first feeding clearance hole 222 and continues to pass through the second feeding clearance hole 211 to reach the processing position (the wiring frame 900 is placed directly below the second feeding clearance hole 211). The bit 35 on the equipment for tightening the screw 800 can screw the screw 800 into the wiring frame 900 through the first feeding clearance hole 222 and the second feeding clearance hole 211.

[0051] For further information, see Figure 5-Figure 6 As a specific embodiment of the automatic screw-in machine provided by the present invention, the feed push plate 23 is provided with a third feed clearance hole 232 for matching with the first feed clearance hole 222; a feed stop block 25 is provided on the side of the feed bottom plate 21 away from the feed guide plate 22, and the feed stop block 25 is provided with a fourth feed clearance hole 251 corresponding to the second feed clearance hole 211. When the screw 800 falls from the first feed clearance hole 222, the feed push plate 23 recovers and receives the next screw 800, and the bit 35 on the device for tightening the screw 800 can penetrate the third feed clearance hole 232 and then penetrate the first feed clearance hole 222 and the second feed clearance hole 211 in sequence to operate the screw 800. The feed push plate 23 does not need to complete the tightening and then recover, which effectively improves the processing rate. In order to ensure that the screw 800 will not deflect after passing through the second feeding clearance hole 211, a feeding limit block 25 is provided, and the screw 800 reaches the wiring frame 900 only after passing through the fourth clearance hole on the feeding limit block 25.

[0052] For further information, see Figure 5-Figure 6As a specific embodiment of the automatic screw-in machine provided by the present invention, two feeding clamps 26 arranged opposite to each other are provided on the feeding limit block 25, and the feeding clamps 26 are rotatably connected to the feeding limit block 25; the side wall of the feeding guide groove 221 has a feeding notch 223, and the feeding track 14 is connected to the feeding guide groove 221 through the feeding notch 223. The wiring frame 900 into which the screw 800 is screwed needs to be unloaded and replaced with the next wiring frame 900. In order to prevent the screw 800 from falling when the next wiring frame 900 is not placed in the processing position, two feeding clamps 26 are provided. The screw 800 cannot pass through the feeding clamps 26 without external force. When it is detected that the wiring frame 900 reaches the processing position, the screw head 35 on the device for tightening the screw 800 presses down to drive the screw 800 through the feeding clamps 26 (when the external force is sufficient, the feeding clamps 26 are driven to rotate relative to the feeding limit block 25 and switch to the open state), and contact the wiring frame 900. The screw head 35 rotates to screw the screw 800 into the wiring frame 900. The feed track 14 extends into the feed guide groove 221 through the feed notch 223. When the feed push plate 23 moves in the feed guide groove 221 so that the feed receiving groove 231 corresponds to the feed track 14, the screw 800 on the feed track 14 enters the feed receiving groove 231. In order to prevent the feeding push plate 23 from driving the screw 800 to move in the direction away from the first feeding clearance hole 222, a blocking hook 142 is set on one side of the first feeding clearance hole 222 of the raw material of the feeding track 14, and a corresponding blocking hook clearance groove 233 is simultaneously set on the feeding push plate 23 for the blocking hook 142 to pass through. Due to the action of the blocking hook 142, the feeding push plate 23 will not drive the screw 800 to move in the direction away from the first feeding clearance hole 222.

[0053] For further information, see Figure 7 As a specific embodiment of the automatic screw-in machine provided by the present invention, the discharging mechanism 4 includes a discharging bottom plate 41, a discharging placement plate 42 provided on the discharging bottom plate 41 and used to place the wiring frame 900, a discharging push plate 43 used to push the wiring frame 900 on the discharging placement plate 42, and a discharging push driving mechanism 44 used to drive the discharging push plate 43 to move. The wiring frame 900 in the feeding pipe 52 is separated from the feeding pipe 52 and reaches the discharging placement plate 42. When the wiring frame 900 is screwed into the screw 800, the discharging push driving mechanism 44 drives the discharging push plate 43 to push the wiring frame 900 that has been screwed into the screw 800 away from the discharging placement plate 42, and the discharging placement plate 42 continues to receive the wiring frame 900 to be processed.

[0054] For further information, see Figure 7As a specific embodiment of the automatic screw-in machine provided by the present invention, the discharge placement plate 42 is provided with a discharge placement groove 421 for placing the wiring frame 900, and the side wall of the discharge placement groove 421 is provided with a discharge placement port 422 for the wiring frame 900 in the feeding pipe 52 to enter the discharge placement groove 421, and the side wall of the discharge placement groove 421 is provided with a contact sensor 423 (which can be a photoelectric sensor), and the discharge placement port 422 and the contact sensor 423 are respectively located on the two opposite side walls of the discharge placement groove 421. The wiring frame 900 in the feeding pipe 52 enters the discharge placement groove 421 from the discharge placement port 422. At this time, the discharge push drive mechanism 44 places the discharge push plate 43 at a position corresponding to the discharge placement port 422, that is, after the wiring frame 900 enters the discharge placement groove 421 from one side, due to the blocking effect of the discharge push plate 43, it does not contact the side wall on the other side (the thickness of the discharge push plate 43 is less than the width of the discharge placement groove 421, so at this time the wiring frame 900 is located in the discharge placement groove 421 but does not contact the side wall on the other side). At this time, the wiring frame 900 is positioned and screwed into the component 3 by screwing the screw 800 into it. When the screwing-in operation of the wiring frame 900 is completed, the discharge pushing drive mechanism 44 pulls the discharge pushing plate 43 away from the position corresponding to the discharge placement port 422, and the wiring frame 900 in the feeding pipe 52 continues to enter the discharge placement slot 421 from the discharge placement port 422, and pushes the wiring frame 900 that has been screwed in to move. When the screwed-in wiring frame 900 approaches or contacts the side wall of the discharge placement slot 421 on which the contact sensor 423 is installed, the contact sensor 423 is triggered to control the discharge pushing drive mechanism 44 to drive the discharge pushing plate 43 to push the screwed-in wiring frame 900 away from the discharge placement slot 421.

[0055] The discharging push driving mechanism 44 is a discharging push cylinder disposed on the discharging bottom plate 41. A discharging pipe 45 is disposed on the discharging bottom plate 41. The discharging pipe 45 is located at one end of the discharging placement plate 42 away from the discharging push cylinder. The discharging push driving mechanism 44 (discharging push cylinder) drives the discharging push plate 43 to push the screwed-in wiring frame 900 away from the discharging placement slot 421 and drop it into the discharging pipe 45, completing the discharging action.

[0056] For further information, see Figure 4As a specific embodiment of the automatic screw-in machine provided by the present invention, a screw-in guide plate 39 is provided on the screw-in mounting plate 31. The screw-in guide plate 39 is located on the side of the screw-in lifting plate 32 away from the screw-in lifting drive mechanism 33. The screw-in guide plate 39 is provided with a screw-in clearance hole for the screw-in bit 35 to pass through. The screw-in bit 35 passes through the screw-in clearance hole to screw in the screw 800, ensuring that the screw-in bit 35 with a certain length will not deviate when used. The screw-in lifting drive mechanism 33 is a screw-in lifting cylinder provided on the screw-in mounting plate 31. A screw-in buffer spring 38 is provided between the piston rod of the screw-in lifting cylinder and the screw-in lifting plate 32 to avoid rigid impact between the screw-in bit 35 and the screw 800.

[0057] For further information, see Figure 4 As a specific embodiment of the automatic screw-in machine provided by the present invention, a hydraulic buffer 321 is provided on the screw-in lifting plate 32, and the hydraulic buffer 321 is arranged on the side of the screw-in lifting plate 32 close to the screw-in guide plate 39; a screw-in guide rail 311 is provided on the screw-in mounting plate 31, and a screw-in slider 322 is provided on the screw-in lifting plate 32 to be slidably connected to the screw-in guide rail 311.
