In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1-Figure 5As shown, an embodiment of the present invention provides a screw driving machine, comprising a discharge mechanism 4 for placing a wiring frame 900 for screwing in screws 800, a feeding mechanism 2 located just above the discharge mechanism 4 and for conveying the screws 800, and a screwing assembly 3 for screwing the screws 800 on the feeding mechanism 2 into the wiring frame 900 on the discharge mechanism 4; the screwing assembly 3 comprises a screwing installation plate 31, a screwing lifting plate 32 slidably connected to the screwing installation plate 31, a screwing lifting drive mechanism 33 for driving the screwing lifting plate 32 to slide, and a screwing drive motor provided on the screwing lifting plate 32. 34, a screwdriver 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 discharging mechanism 4 includes a discharging bottom plate 41, a discharging placement plate 42 arranged on the discharging bottom plate 41 and used to place the wiring frame 900, a discharging push plate 43 for pushing the wiring frame 900 on the discharging placement plate 42, and a discharging push driving mechanism 44 for driving the discharging push plate 43 to move.

[0032] In an embodiment of the present invention, the working process of the screw driving machine is as follows: a wiring frame 900 into which a screw 800 is to be screwed is placed on the discharge mechanism 4, the feeding mechanism 2 is used to feed the screw 800 to the bottom of the screw bit 35, and the screwing assembly 3 is used to screw the screw 800 on the feeding mechanism 2 into the wiring frame 900 into which the screw 800 is to be screwed on the discharge mechanism 4; the screwing-in lifting drive mechanism 33 drives the screwing-in lifting plate 32 to move downward, so that the screw bit 35 contacts the screw 800 on the feeding mechanism 2, and the screwing-in drive motor 34 drives the screw 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, thereby achieving the screwing of the screw 800 into a preset depth, thereby improving the tightening efficiency of the screw 800.

[0033] The discharge placement plate 42 on the discharge mechanism 4 is used to place the wiring frame 900 to be processed. When the wiring frame 900 is screwed in with the screws 800, the discharge push drive mechanism 44 drives the discharge push plate 43 to push the wiring frame 900 with the screws 800 screwed in away from the discharge placement plate 42, and then use an external loading device to place the wiring frame 900 to be processed on the discharge placement plate 42 or manually place the wiring frame 900 on the discharge placement plate 42.

[0034] For further information, see Figure 3-Figure 4As a specific embodiment of the screw driving 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 accommodating the screw 800, 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. The feeding mechanism 2 is used to feed the screw 800 to the bottom of the screwdriver bit 35. The specific process is as follows: the screw 800 is placed in 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 under the second feeding clearance hole 211). The screwdriver bit 35 on the device 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.

[0035] For further information, see Figure 3-Figure 4 As a specific embodiment of the screw driving 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 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.

[0036] For further information, see Figure 3-Figure 4As a specific embodiment of the screw driving 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 screw 800 is placed in the feeding receiving groove 231 through the feeding notch 223. After the wiring frame 900 has been screwed in, it is necessary to remove the material and replace it 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 clamp 26 without external force. When it is detected that the wiring frame 900 has reached the processing position, the screwdriver bit 35 on the device for tightening the screw 800 is pressed down to drive the screw 800 through the feeding clamp 26 (when the external force is sufficient, the feeding clamp 26 is driven to rotate relative to the feeding limit block 25 and switch to the open state), contacting the wiring frame 900, and the screwdriver bit 35 is rotated to screw the screw 800 into the wiring frame 900. The external feeding track or the screw 800 is manually extended into the feeding guide groove 221 through the feeding notch 223. When the feeding push plate 23 moves in the feeding guide groove 221 so that the feeding receiving groove 231 corresponds to the feeding notch 223, the screw 800 on the feeding track enters the feeding receiving groove 231 (or the screw 800 is manually placed into the feeding receiving groove 231).

[0037] For further information, see Figure 6As a specific embodiment of the screw driving 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 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 external loading mechanism or manual operation places the wiring frame 900 from the discharge placement port 422 into the discharge placement slot 421. 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 slot 421 from one side, it does not contact the side wall on the other side due to the blocking effect of the discharge push plate 43 (the thickness of the discharge push plate 43 is less than the width of the discharge placement slot 421. Therefore, at this time, the wiring frame 900 is located in the discharge placement slot 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. The screw 800 is screwed into the wiring frame 900. When the screwing-in operation 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. Subsequently, the wiring frame 900 that enters the discharge placement slot 421 from the discharge placement port 422 pushes the wiring frame 900 that has been screwed in to move. When the wiring frame 900 that has been screwed in 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 wiring frame 900 that has been screwed in away from the discharge placement slot 421.

[0038] For further information, see Figure 6 As a specific embodiment of the screw driving machine provided by the present invention, the discharge pushing driving mechanism 44 is a discharge pushing cylinder provided on the discharge bottom plate 41, and a discharge pipe 45 is provided on the discharge bottom plate 41. The discharge pipe 45 is located at one end of the discharge placement plate 42 away from the discharge pushing cylinder. The discharge pushing driving mechanism 44 (discharge pushing cylinder) drives the discharge pushing plate 43 to push the screwed-in wiring frame 900 away from the discharge placement slot 421 and drop it into the discharge pipe 45, completing the discharge action.

[0039] For further information, see Figure 5 As a specific embodiment of the screw driving machine provided by the present invention, the screwing-in lifting drive mechanism 33 is a screwing-in lifting cylinder arranged on the screwing-in mounting plate 31, and a screwing-in buffer spring 38 is provided between the piston rod of the screwing-in lifting cylinder and the screwing-in lifting plate 32 to avoid rigid impact between the screw bit 35 and the screw 800.

[0040] For further information, see Figure 5As a specific embodiment of the screw driving machine provided by the present invention, a screw driving guide plate 39 is provided on the screw driving installation plate 31, and the screw driving guide plate 39 is located on the side of the screw driving lifting plate 32 away from the screw driving lifting driving mechanism 33, and a screw driving hole for the screw driving bit 35 is provided on the screw driving guide plate 39. The screw driving bit 35 passes through the screw driving hole to drive the screw 800, so as to ensure that the screw driving bit 35 with a certain length will not be offset when used.

[0041] For further information, see Figure 5 As a specific embodiment of the screw driving machine provided by the present invention, a hydraulic buffer 321 is provided on the screw driving lifting plate 32, and the hydraulic buffer 321 is located on the side of the screw driving lifting plate 32 close to the screw driving guide plate 39. The hydraulic buffer 321 and the screw driving position sensor 36 can achieve synergy, thereby limiting the height of the screw driving lifting plate 32 to be lowered.

[0042] For further information, see Figure 5 As a specific embodiment of the screw driving machine provided by the present invention, a screwing guide rail 311 is provided on the screwing installation plate 31, and a screwing slider 322 slidably connected to the screwing guide rail 311 is provided on the screwing lifting plate 32.
