In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] Please refer to Figure 1-Figure 6 The present embodiment provides an air-blowing screw-driving device for automatically locking screws on a workpiece. The air-blowing screw-driving device adopts an air-blowing feeding method and is used in conjunction with an air-blowing feeding device, and is particularly suitable for feeding long screws. The air-blowing screw-driving device mainly includes a machine base 100, an electric screw-driving mechanism 10 and a material receiving mechanism 20 installed on the machine base 100. The material receiving mechanism 20 is used to receive the screws fed from the air-blowing feeding device. The electric screw-driving mechanism 10 can absorb the screws from the material receiving mechanism 20 and automatically lock the screws into the corresponding screw holes on the workpiece.

[0053] For further information, please refer to Figure 2 and Figure 3 The air-blowing screw-driving device also includes a lifting plate 101 and a first lifting drive mechanism 200. The lifting plate 101 is slidably installed on the machine base 100 along the vertical direction through a slide rail slider structure. The electric screw-driving mechanism 10 is installed on the lifting plate 101, that is, the electric screw-driving mechanism 10 is slidably installed on the machine base 100 through the lifting plate 101; the first lifting drive mechanism 200 is installed on the machine base 100, and the output end of the first lifting drive mechanism 200 is connected to the lifting plate 101 to drive the lifting plate 101 to rise and fall in the vertical direction to adjust the height according to the locking position.

[0054] For example, please continue to refer to Figure 2 and Figure 3 The first lifting drive mechanism 200 includes a first lifting drive member 201, a screw rod 203 and a screw rod nut 204, wherein the first lifting drive member 201 is a rotary motor, fixedly mounted on the machine base 100 through a first mounting seat 202, the screw rod 203 is arranged in the vertical direction and connected to the output shaft of the first lifting drive member 201, the screw rod nut 204 is threadedly connected to the screw rod 203, and is sequentially connected to the lifting plate 101 through a connecting block 205, a first connecting plate 206 and a second connecting plate 207. When the first lifting drive member 201 rotates, the screw rod 203 is driven to rotate. Since the rotational freedom of the screw rod nut 204 is limited by the lifting plate 101, the screw rod nut 204 can only rise or fall vertically along the screw rod 203, driving the lifting plate 101 and the electric screw driving mechanism 10 mounted thereon to rise and fall, thereby realizing the adjustment of the locking height.

[0055] For example, please continue to refer to Figure 2 and Figure 3 The air-blowing screw-driving device also includes a second lifting drive mechanism 300 installed on the lifting plate 101. The electric screw-driving mechanism 10 is slidably installed on the lifting plate 101 along the vertical direction. The output end of the second lifting drive mechanism 300 is connected to the electric screw-driving mechanism 10 to drive the electric screw-driving mechanism 10 to lift and lower in the vertical direction, thereby driving the electric screw-driving mechanism 10 to move downward to approach the material receiving mechanism 20 or the workpiece to be screwed.

[0056] For example, the electric screw driving mechanism 10 can float in the vertical direction to avoid damage to the equipment or workpiece due to rigid contact. Figure 2 and Figure 3The second lifting drive mechanism 300 includes a second lifting drive member 301 and an elastic connection component. The second lifting drive member 301 is installed on the lifting plate 101 through a second mounting seat 302. The second lifting drive member 301 adopts a linear cylinder, and its output shaft is set downward. One end of the elastic connection component is connected to the output end of the second lifting drive member 301, and the other end is connected to the electric screw driving mechanism 10. The two ends of the elastic connection component can be elastically extended and retracted in the vertical direction to provide a buffer space for the electric screw driving mechanism 10.

[0057] For further information, please refer to Figure 2 and Figure 3 The electric screw driving mechanism 10 is fixed to the sliding seat 102, and the sliding seat 102 is slidably installed on the lifting plate 101 through a slider rail structure. The elastic connection component includes a connecting guide rod 303, a compression spring 304, a first limiting ring 305 and a second limiting ring 306. The upper end of the connecting guide rod 303 is connected to the output shaft of the second lifting drive member 301, and an avoidance gap 1021 is provided on the sliding seat 102. The lower end of the connecting guide rod 303 penetrates into the sliding seat 102 and passes out from the avoidance gap 1021. The compression spring 304 is sleeved outside the connecting guide rod 303, the first limiting ring 305 and the second limiting ring 306 are respectively fixed to the connecting guide rod 303, and the compression spring 304 is limited between the first limiting ring 305 and the lifting plate 101. The second limiting ring 306 is located in the avoidance gap 1021 to prevent the connecting guide rod 303 from detaching from the sliding seat 102. Specifically, when the output end of the electric screw driving mechanism 10 presses against the workpiece or the material receiving mechanism 20 directly or indirectly through the screw, the sliding seat 102 moves upward, the compression spring 304 is compressed, and the electric screw driving mechanism 10 has a certain buffer space to achieve the effect of floating and elastic contact.

[0058] For further information, please refer to Figure 2 and Figure 3 The electric screw driving mechanism 10 includes an electric screwdriver head 11 and a screw driving motor 12. The screw driving motor 12 is fixed to the sliding seat 102 through a third mounting seat 13. The output shaft of the screw driving motor 12 is arranged downward. The electric screw driver head 11 is mounted on the output shaft of the screw driving motor 12. The screw driving motor 12 drives the electric screw driver head 11 to rotate around its own axis to realize the function of automatically locking the screw. The lower end of the electric screw driver head 11 has a groove structure for accommodating a nut of a screw and a magnet structure for sucking the screw. The screw driving motor 12 and the electric screw driver head 11 are both prior art, and their specific structures and working principles are not repeated here.

[0059] For example, please refer to Figure 2-Figure 6The material receiving mechanism 20 is arranged below the electric screw driving mechanism 10. The material receiving mechanism 20 includes a horizontal driving member 23, a material receiving fixture 24 and a material receiving pipe 25. The material receiving fixture 24 is provided with a material receiving hole 241. The output end of the horizontal driving member 23 is connected to the material receiving fixture 24 to drive the material receiving fixture 24 to transfer between the material receiving station and the material taking station. The material receiving pipe 25 is arranged at the material receiving station. The upper end of the material receiving pipe 25 is connected to the air blowing feeding device through a hose 400. When the material receiving fixture 24 is located at the material receiving station, the lower end of the material receiving pipe 25 faces the material receiving hole 241, and forms an avoidance space below the electric screw driver 11. On the one hand, the material receiving fixture 24 can continue to receive the screw material, and on the other hand, the electric screw driving mechanism 10 can perform the operation of locking the screw at the same time; when the material receiving fixture 24 is located at the material taking station, the electric screw driver 11 is located above the material receiving hole 241 so that the electric screw driver 11 can absorb the screw.

[0060] Specifically, the air-blowing screw-driving device provided in this embodiment includes an electric screw-driving mechanism 10 and a material receiving mechanism 20 which are separately arranged. The material receiving mechanism 20 receives the screws fed by air through a material receiving jig 24, and the horizontal driving member 23 drives the material receiving jig 24 to move the material receiving jig 24 in the horizontal direction, so that the material receiving jig 24 can reciprocate between the material receiving station and the material taking station. When the material receiving jig 24 is located at the material receiving station, the lower end of the material receiving pipe 25 is directly opposite to the material receiving hole 241 to receive the screws fed by air, and an avoidance space is formed below the electric screwdriver head 11, so as not to hinder the electric screw-driving mechanism 10 from performing the screw-driving action at the same time; when the material receiving jig 24 is located at the material taking station, the electric screwdriver head 11 is located above the material receiving hole 241, and can directly suck up the screws in the material receiving hole 241. In summary, the screw feeding action and screw driving action of the air-blowing screw driving device provided in this embodiment can be executed simultaneously, with high working efficiency. The double-station setting reduces the control difficulty, and due to the split structural setting, when the screw is stuck, only part of the docking mechanism 20 needs to be checked, thereby shortening the downtime.

[0061] For example, please refer to Figure 4-Figure 6The material receiving mechanism 20 also includes a mounting plate 21, a connecting plate 22 and a sliding plate 26. The mounting plate 21 is arranged parallel to the machine base 100 and are both arranged in a vertical plane. The mounting plate 21 is fixed to the lower end of the machine base 100 through two connecting plates 22. The horizontal driving member 23 is fixed to the mounting plate 21. The material receiving pipe 25 is fixed to the connecting plate 22 on one side through a fixing seat 251. A horizontal slide rail 262 extending in the horizontal direction is provided on the mounting plate 21. The sliding plate 26 is slidably arranged on the horizontal slide rail 262 through a horizontal slider 263. The output end of the horizontal driving member 23 is connected to the sliding plate 26 through a transmission plate 264. The material receiving fixture 24 is fixed to the sliding plate 26. The horizontal driving member 23 can be extended and retracted along a straight line to drive the material receiving fixture 24 to transfer between the material receiving station and the material taking station. The mounting plate 21 and the sliding plate 26 are both arranged in the vertical direction, and the material receiving jig 24 is arranged in the horizontal direction. This arrangement improves the compactness of the structure. The mounting plate 21 and the sliding plate 26 are always in a position to avoid the electric screwdriver head 11, which can reduce the space occupied in the thickness direction. The material receiving jig 24 is arranged in a horizontal plane and is connected to the bottom of the sliding plate 26, which reduces the height difference between the material suction height and the locking height of the electric screwdriver head 11, shortens the lifting stroke, and can further improve the working efficiency.

[0062] Exemplarily, the horizontal driving member 23 may be a linear driving element such as an electric push rod, a linear cylinder, etc. In this embodiment, the horizontal driving member 23 is a linear cylinder.

[0063] Exemplarily, a recessed groove structure is provided at the upper end of the material receiving hole 241 to accommodate the nut of the screw. A buffer washer 2411 is provided in the recessed groove structure to support the nut of the screw. When the electric screwdriver bit 11 is pressed down, the buffer washer 2411 is squeezed and absorbs the impact, thereby protecting the material receiving fixture 24 from impact.

[0064] For example, please refer to Figure 4-Figure 6 The sliding plate 26 is provided with a limiting protrusion 261, and the mounting plate 21 is provided with two buffers 28, which are respectively installed at both ends of the sliding direction of the limiting protrusion 261 through buffer seats 281 to limit the sliding range of the sliding plate 26. The buffer 28 can be a hydraulic buffer, a spring buffer, etc.

[0065] For example, please continue to refer to Figure 4-Figure 6 The material receiving fixture 24 is also provided with a detection hole 242, and the detection hole 242 is connected to the material receiving hole 241. The material receiving mechanism 20 also includes a material receiving detection piece 29, and the detection end of the material receiving detection piece 29 is arranged toward the detection hole 242. The material receiving detection piece 29 is used to detect the screw in the material receiving hole 241 to automatically determine whether the screw is in the preset position in the material receiving hole 241.

[0066] For example, the material receiving detection element 29 can be an infrared sensor, an ultrasonic sensor, a proximity switch or other detection element. Figure 4-Figure 6 The material receiving detection member 29 adopts an infrared sensor, including a transmitting end and a receiving end. The detection hole 242 is set as a through-hole structure, which passes through the bottom of the material receiving fixture 24 in the horizontal direction. One of the transmitting end and the receiving end is installed on the side of the material receiving fixture 24 through the lower connecting plate 291, and the other is directly fixed to the bottom of the material receiving fixture 24. When there is no screw in the material receiving hole 241, the infrared ray emitted by the transmitting end is received by the receiving end; when the screw is in the preset position in the material receiving hole 241, the screw blocks the infrared ray emitted by the transmitting end, and the receiving end cannot receive the infrared signal and sends out a corresponding detection signal.

[0067] For example, please continue to refer to Figure 4-Figure 6 The material receiving mechanism 20 also includes a material shifting plate 27, which is fixed to a fixing seat 251. The material shifting plate 27 is disposed above the material receiving fixture 24, and the material shifting plate 27 is located between the material receiving station and the material taking station. The material shifting plate 27 limits the height of the highest point of the screw. If the screw loaded into the material receiving hole 241 has a slight posture deviation, when the horizontal driving member 23 drives the material receiving fixture 24 carrying the screw to move toward the material taking station, the material shifting plate 27 can, on the one hand, adjust the screw to achieve the effect of posture fine-tuning, and on the other hand, it can also block the screw whose material receiving deviation is too serious, thereby avoiding serious interference when the electric screwdriver head 11 descends to absorb the material.

[0068] For example, please refer to Figure 4 The material removal plate 27 is configured as an L-shaped plate structure, including a vertical section and a horizontal section. The upper end of the vertical section is connected to the side wall of the fixed seat 251, and the horizontal section is connected to the lower end of the vertical section. The horizontal section contacts the screw through its bottom surface, and both ends of the horizontal section in the translation direction of the material receiving fixture 24 are provided with chamfered structures to improve the smoothness when fine-tuning the screw posture.

[0069] For example, please refer to Figure 2 The air-blowing screw driving device further includes a visual detection component 500, which is mounted on the base 100 and located beside the electric screw driving mechanism 10. The visual detection component 500 is used to detect the position and posture of the screw hole and / or the screw. The visual detection component 500 adopts a visual detection structure in the prior art, including an image acquisition part and an auxiliary light source part, and its specific structure and working principle are not described in detail here.

[0070] For example, please refer to Figure 2 and Figure 3The air-blowing screw-driving device also includes a control module 600, which is arranged on the top of the machine base 100. The control module 600 is electrically connected to the electric screw-driving mechanism 10, the material receiving mechanism 20, the first lifting drive mechanism 200, the second lifting drive mechanism 300 and the visual detection component 500. The control module 600 can select a single-chip microcomputer or a programmable logic controller that can install and run a control program to control the operation of the electric screw-driving mechanism 10, the material receiving mechanism 20, the first lifting drive mechanism 200, the second lifting drive mechanism 300 and the visual detection component 500 that are electrically connected thereto.

[0071] For example, please refer to Figure 1 The air-blowing screw driving device further includes a protective cover 103, which is arranged outside the control module 600, the electric screw driving mechanism 10, the first lifting drive mechanism 200 and the second lifting drive mechanism 300, and can effectively protect the internal structure. Furthermore, a handle 104 is provided on the protective cover 103 to facilitate the staff to disassemble and install the protective cover 103.

[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
