DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] like Figure 1 and Figure 2 As shown, the screw driving device of the present invention comprises a screw driving assembly and a driving member 5.

[0022] Specifically, the screw driving assembly includes a nail suction tube 1, a nail extraction tube 2 and an electric screwdriver 4. The nail suction tube 1 has a nail storage chamber 11, which is arranged along the length direction of the ceiling tube 1 and has an openable or closable nail suction port 13 at one end. The nail extraction tube 2 is integrated on the nail suction tube 1 and has a nail extraction chamber 21. The nail extraction chamber 21 and the nail storage chamber 11 are connected through a nail feeding channel 6, and one end of the nail extraction chamber 21 has a nail extraction port 22 and the other end has a screwdriver interface 23. The nail extraction port 22 and the nail suction port 13 are located on the same side. The electric screwdriver 4 is connected at the screwdriver interface 23. The driving member 5 is connected to the nail extraction tube 2 and is used to drive the screw 8 in the nail storage chamber 11 to move into the nail extraction chamber 21 through the nail feeding channel 6.

[0023] Preferably, in the length direction of the ceiling pipe 1, the nail outlet pipe 2 is arranged adjacent to the nail suction port 13. Considering that the screw 8 is usually screwed downward when the screw is actually driven. Figure 1 and Figure 2 As shown, the nail suction tube 1 is a long tube extending vertically, and has a nail suction port 13 at its lower end. The nail output tube 2 is connected to one side of the nail suction tube 1 and is adjacent to the lower end of the nail suction tube 1. The nail output port 22 is located at the lower end of the nail output tube 2, and the screwdriver interface 23 is located at the upper end of the nail output tube 2. Before the screw driving operation is performed, the nail suction tube 1 can be used to store enough screws 8, and the screws 8 are sequentially opposite in the head-to-tail direction in the up-down direction, and the screw 8 located at the lowest end is opposite to the nail feeding channel 6.

[0024] When the screw 8 is being driven, the driving member 5 can drive the screw 8 at the bottom to be transferred into the nail removal cavity 21, and then the electric screwdriver 4 is started to drive the screw 8. As the screw 8 is transferred, under the action of gravity, the screws 8 located above will slide down in sequence to the position opposite to the nail feeding channel 6 to facilitate the next screw driving operation. The entire screw 8 conveying process does not require manual operation, eliminating the operation interval.

[0025] It can be understood that the screw driving device of the present application can use the nail suction tube 1 to store a sufficient number of screws 8 at a time, and the driving member 5 can continuously transfer a single screw 8 to the nail removal cavity 21 according to the screw driving rhythm, thereby realizing batch continuous screw driving and improving work efficiency. Moreover, since the nail suction tube 1 can store multiple screws 8, there is no need to carry a nail box during manual operation, which is convenient for single-person operation.

[0026] In the screw driving device of the embodiment of the present invention, the nail suction tube 1 has a nail storage chamber 11, and the nail output tube 2 is installed on one side of the nail suction tube 1 and has a nail output chamber 21 connected to the nail storage chamber 11. One end of the nail storage chamber 11 and the nail output chamber 21 respectively has a nail suction port 13 and a nail output port 22, and the electric screwdriver 4 is connected to the screwdriver interface 23 opposite to the nail output port 22. The nail storage chamber 11 can store a plurality of screws 8, and the driving member 5 is used to drive the screws 8 in the nail storage chamber 11 to move toward the nail output chamber 21. Thus, the driving member 5 can transfer the plurality of screws 8 in the nail storage chamber 11 to the nail output chamber 21 in sequence according to the screw driving rhythm, thereby achieving the purpose of single nailing and batch continuous screwing 8, thereby improving the working efficiency. Moreover, since the nail suction tube 1 can store a plurality of screws 8, there is no need to carry a nail box with you during manual operation, which is convenient for single-person operation.

[0027] Furthermore, if Figure 1 and Figure 2 As shown, the screw driving assembly also includes a blocking block 3 and a nail sucking member 12. The nail sucking member 12 is arranged at one end of the nail storage chamber 11 away from the nail sucking port 13. The blocking block 3 is connected to the nail sucking tube 1 and is located at the nail sucking port 13. The blocking block 3 can be moved relative to the nail sucking tube 1 to open or close the nail sucking port 13. Therefore, when it is necessary to fill the screw 8 into the nail sucking tube 1, the blocking block 3 can be moved to open the nail sucking port 13, and the nail sucking port 13 is aligned with the nail box, and then the nail sucking member 12 is used to suck the screw 8 into the nail storage chamber 11 through the nail sucking port 13. After the nail storage chamber 11 is full, the blocking block 3 is moved to close the nail sucking port 13. That is, the screw driving device of the present application can automatically suck nails without manual nailing, further improving its operational convenience.

[0028] Optionally, the nail sucking member 12 is a proportionally adjusted pneumatic suction nozzle. Specifically, when the nail sucking tube 1 is filled with screws 8, the air source of the proportionally adjusted pneumatic suction nozzle can be connected, and the nail sucking port 13 is aligned with the nail box to suck nails.

[0029] Furthermore, the blocking block 3 includes a blocking surface facing the nail storage cavity 11, and the blocking surface is connected to the bottom wall of the nail delivery channel 6. It can be understood that after the blocking block 3 blocks the nail suction port 13, the blocking surface can be supported on the bottom of the screw 8, and the blocking surface and the bottom wall of the nail delivery channel 6 can form a flat surface, thereby ensuring the smoothness of the screw 8 from the nail storage cavity 11 to the nail delivery cavity 21.

[0030] Preferably, if Figure 1 and Figure 2 As shown, the nail feeding channel 6 is inclined in a direction away from the nail storage cavity 11 and toward the opening direction of the nail suction port 13. Figure 1 and Figure 2 As shown, the nail feeding channel 6 extends downwardly at an angle, so that it can play a guiding role when the screw 8 is transferred, ensuring that the screw 8 can be transferred smoothly and improving the reliability of the continuous screw driving operation.

[0031] Preferably, the blocking surface extends obliquely toward the bottom wall of the nail feeding channel 6. Figure 1 and Figure 2 As shown, the blocking surface extends downwardly and forms a flat inclined surface with the inner bottom surface of the nail feeding channel 6, so that when the driving member 5 drives the screw 8 to move, the auxiliary screw 8 can slide into the nail extraction cavity 21.

[0032] It should be noted that the size of the nail feeding channel 6 needs to be determined according to the size of the screw 8. Specifically, it is necessary to ensure that the size of the nail feeding channel 6 in the height direction is slightly larger than the height of a single screw 8 to allow the screw 8 to pass smoothly. In addition, the height of the nail feeding channel 6 should not exceed 1.5 times the height of a single screw 8, so as to avoid two or more screws 8 passing through the nail feeding channel 6 and moving toward the nail removal cavity 21 at the same time during a single nail feeding process, thereby ensuring the reliability of the operation.

[0033] Preferably, the screw driving assembly further comprises a guide cover 7, which is connected to the nail suction port 13 and whose cross-sectional area gradually increases in a direction away from the nail suction port 13. Figure 1 and Figure 2 As shown, the upper end of the guide cover 7 is connected to the nail suction port 13, and the lower end has a flared opening, that is, the guide cover 7 has a "trumpet-shaped" flared opening structure, which can assist the screws 8 in the nail box to move toward the nail suction port 13 when the nail suction tube 1 sucks nails.

[0034] Preferably, the driving member 5 is an electromagnet suction assembly, which includes an electromagnet disposed on the outer wall of the nail-exiting tube 2 and a relay for controlling the indirect on and off of the electromagnet. It is understandable that the screw 8 is mostly made of ferromagnetic material, and the magnetic force generated by the electromagnet can suck the screw 8 from the nail storage cavity 11 into the nail-exiting cavity 21 to achieve the transfer of the screw 8. Moreover, since the relay can control the high-frequency and intermittent on and off of the electromagnet, it is convenient to control the continuous transfer of the screw 8 according to the rhythm of screw driving.

[0035] Optionally, the electromagnet suction assembly further includes a control circuit connected to the electromagnet and a circuit switch disposed on the control circuit. When the screw needs to be transferred to the nail cavity 21, the circuit switch opens the control circuit to allow the electromagnet to generate magnetic force; after the screw is driven, the circuit switch closes the control circuit. It is understandable that the circuit switch can be manually controlled, or a sensor capable of detecting the operating status can be provided, and the detection information of the sensor can be used to automatically control the opening and closing of the circuit switch.

[0036] Preferably, the electromagnet is located on the side wall of the nail outlet tube 2 opposite to the nail feeding channel 6. Thus, the magnetic force generated by the electromagnet can adsorb the screw 8 along the extension direction of the nail feeding channel 6, ensuring the accuracy of the screw 8 being transferred into place.

[0037] Optionally, the driving member 5 is not limited to being an electromagnet, and the driving member 5 may also be a pneumatic member, as long as it can satisfy the transfer of the screw 8 .

[0038] Furthermore, the screw driving device further includes a control component connected to the nail driving tube 2, the control component includes a controller and a photosensitive sensor, the photosensitive sensor is arranged in the nail driving cavity 21 to detect whether the screw 8 moves to the nail driving cavity 21, and the controller controls the action of the electric screwdriver 4 according to the detection information of the photosensitive sensor. Thus, the control component can automatically determine whether the screw 8 is assembled in place, and control the electric screwdriver 4 to automatically operate, thereby optimizing the operation mode and improving the screw driving efficiency.

[0039] Preferably, the housing of the electric screwdriver 4 is directly connected to the nail sucking tube 1. In other words, the electric screwdriver 4, the nail sucking tube 1 and the nail pulling tube 2 are connected in pairs, and the overall structure is compact and stable, which is convenient for one person to carry.

[0040] Preferably, the nail suction tube 1 and the nail extraction tube 2 are formed in one piece, which further improves the structural strength and compactness, and saves production costs compared to independently producing two structural parts.
