Description

Technical Field

[0001] This application relates to the technical field of screw assembly, and in particular to a screw locking device. Background Art

[0002] In the process of machining and assembly, screws are often required to achieve the functions of fastening and connection. At present, when assembling screws, the screws are generally directly blown onto the chuck structure through a blowing structure, and the screws are clamped by the chuck structure. Subsequently, the screws are locked at a preset position by an electric bit, thereby realizing the installation of the screws.

[0003] However, since the blowing structure directly blows the screws onto the chuck structure, and the chuck structure can only achieve the clamping function of the screws, when the screws are clamped by the chuck structure, problems such as screw deflection and inclination are likely to occur. Especially for the three-combination screws including flat washers and spring washers, the screws are extremely prone to tilting, which in turn leads to a reduction in the qualified rate of screw locking.

[0004] In the above related technologies, there is a defect that the screws are prone to tilting during locking and installation, which affects the locking qualified rate. Utility Model Content

[0005] In order to improve the problem of easy tilting during screw locking and increase the qualified rate of screw locking, this application provides a screw locking device.

[0006] The screw locking device provided by this application adopts the following technical solutions:

[0007] A screw locking device includes: a support mechanism; a feeding mechanism disposed on the support mechanism, the feeding mechanism being used for outputting screws; a carrying mechanism, the carrying mechanism being disposed below the feeding mechanism, the carrying mechanism being movable, the carrying mechanism including a carrying plate and a guiding member, the guiding member connecting the carrying plate, the guiding member being used for carrying screws, the guiding member being provided with a guiding groove, the guiding groove extending in the vertical direction, so that the axis of the screw in the guiding groove is vertically arranged, the upper area of the guiding groove being larger than the lower area of the guiding groove, so that the head of the screw is placed above the screw rod; a pushing mechanism, the fixed end of the pushing mechanism being connected to the support mechanism, the movable end of the pushing mechanism being connected to the carrying plate, the pushing mechanism driving the carrying plate to move; a locking mechanism connected to the support mechanism, the locking mechanism being disposed on one side of the pushing mechanism, the movable end of the pushing mechanism being used for driving the carrying mechanism to move below the locking mechanism, so that the locking mechanism drives the screw on the carrying mechanism to move to a preset position and lock.

[0008] By adopting the above technical solution, the supporting mechanism provides support for the feeding mechanism, the pushing mechanism and the locking mechanism. The feeding mechanism is used to output screws into the guiding member. Since the guiding groove of the guiding member extends vertically and the upper area of the guiding groove is larger than the lower area, it can adapt to the characteristic that the cross-sectional area of the head of the screw is larger than that of the screw rod. While the axis of the screw extends vertically and the head of the screw is located above the screw rod, a stable supporting effect on the screw is achieved. Moreover, for the three-component screw including a flat washer and a spring washer, the funnel-shaped structure of the guiding groove can also easily achieve the guiding and supporting effects on the screw, thereby improving the problem that the screw is prone to tilting during locking, so as to improve the qualified rate of screw locking. After the screw is stably placed in the guiding member, the pushing mechanism drives the bearing plate to move, so that the guiding member can move to the lower part of the locking mechanism. The locking mechanism drives the screw to move to a preset position. Since the posture of the screw is corrected by the guiding member, the axis of the screw is more easily ensured to extend vertically. Therefore, when the locking mechanism locks the screw, the risk of difficult locking and poor locking quality caused by the inclination of the screw can be reduced, which helps to reliably lock the screw and improve the qualified rate of screw locking.

[0009] Optionally, the pushing mechanism includes a fixing plate and a telescopic member. The fixing plate is connected to the supporting mechanism. The fixed end of the telescopic member is connected to the fixing plate, and the movable end of the telescopic member is connected to the bearing plate, so that the bearing plate drives the guiding member to reciprocate between the lower part of the feeding mechanism and the lower part of the locking mechanism.

[0010] By adopting the above technical solution, the fixing plate is used to connect the fixed end of the telescopic member to the supporting mechanism. The movable end of the telescopic member drives the bearing plate to move, so that the guiding member can move between the lower part of the feeding mechanism and the lower part of the locking mechanism, so that the feeding mechanism and the locking mechanism can be horizontally distributed, reducing the occupied area of the vertical space. Moreover, the guiding member moves horizontally under the push of the pushing mechanism, which can reduce the risk of tilting of the screw during the movement of the guiding member, helping to improve the qualified rate of screw locking.

[0011] Optionally, the locking mechanism includes a moving component, a mounting bracket, a first driving member and a bit. The moving component is respectively connected to the supporting mechanism and the mounting bracket. The moving component drives the mounting bracket to move. The first driving member is connected to the mounting bracket. The bit is connected to the output end of the first driving member. The first driving member drives the bit to rotate, and the bit is used to lock the screw.

[0012] By adopting the above technical solution, the moving component is used to drive the mounting bracket to move in space, so as to realize the overall movement of the mounting bracket, enabling the locking mechanism to reciprocate between above the guiding member and above the preset position, so that the locking mechanism can take out the screw from the guiding member, then drive the screw to move to the preset position, and through the movement of the moving component and the driving of the first driving member to rotate the bit, the bit realizes the locking of the screw.

[0013] Optionally, the locking mechanism includes a suction component, the suction component is connected to the mounting bracket, the suction component is arranged below the bit, and the suction component is used to suck up the screw and drive the screw to move, and the bit can pass through the suction component to lock the screw.

[0014] By adopting the above technical solution, the suction component is used to suck up the screw to realize the driving and moving effect on the screw. After the suction component sucks up the screw, the moving component drives the mounting bracket to move to the preset position, places the screw at the preset position, and the bit passes through the suction component to be able to contact the screw to realize the locking of the screw.

[0015] Optionally, the suction component includes a suction pipe and a vacuum driving member. The suction pipe is hollow, the upper end of the suction pipe is connected to the mounting bracket, the lower end of the suction pipe is used to suck up the screw, and the vacuum driving member is communicated with the suction pipe, and the vacuum driving member is used to form a negative pressure in the suction pipe.

[0016] By adopting the above technical solution, the suction pipe is connected to the mounting bracket, so that it can move with the mounting bracket. The vacuum driving member forms a negative pressure environment in the hollow suction pipe, so that the screw can be sucked up through the lower end of the suction pipe and the position conversion is realized under the drive of the movement of the mounting bracket; moreover, the hollow suction pipe can allow the bit to pass through, so as to realize the locking of the screw at the lower end of the suction pipe, and can also keep sucking the screw to keep the screw vertical while the bit locks the screw, which helps to improve the success rate of screw locking.

[0017] Optionally, the locking mechanism includes a first buffer component. The first buffer component includes a housing and a first elastic member. The housing is arranged above the suction component. One end of the housing is connected to the mounting bracket, the other end of the housing is movably connected to the suction component, the first elastic member is arranged in the housing, and the suction component is connected to the first elastic member, so that the suction component can move vertically under the elastic action.

[0018] By adopting the above technical solution, the housing is provided. On the one hand, it can realize the connection between the air suction component and the mounting bracket. On the other hand, the housing provides a receiving space for the first elastic member. The upper end of the housing is connected to the mounting bracket, and the other end is movably connected to the air suction component. The upper end of the air suction component is connected to the first elastic member inside the housing, so that the air suction component can move vertically relative to the housing under the elastic action of the first elastic member. Thus, the impact between the air suction component and the guiding member or the screw can be buffered by the first buffer component, and it is convenient to compensate for the height difference between the air suction component and the guiding member, as well as the height difference between the air suction component driving the screw and the preset position, thereby improving the reliability of the device and the qualified rate of screw locking.

[0019] Optionally, the locking mechanism includes a second driving member. The fixed end of the second driving member is connected to the mounting bracket, the movable end of the second driving member is connected to the first driving member, the first driving member is slidably connected to the mounting bracket, and the second driving member drives the first driving member to move in the vertical direction.

[0020] By adopting the above technical solution, the second driving member is used to drive the first driving member to move vertically, so that the bit can be driven to rotate by the first driving member and the bit can be driven to move vertically by the second driving member, enabling the bit to accurately maintain contact with the screw, thereby realizing the locking of the screw.

[0021] Optionally, the locking mechanism includes a second buffer component. The second buffer component is arranged on the mounting bracket. The movable end of the second driving member is connected to the first driving member through a connecting plate, so that the axes of the second driving member and the first driving member are not on the same straight line. The second buffer component is arranged below the connecting plate. The second buffer component has elasticity and can abut against the connecting plate.

[0022] By adopting the above technical solution, the first driving member and the second driving member are not on the same straight line. Thus, after the second buffer component abuts against the connecting plate, it can use its own elastic action to buffer the impact force when the second driving member moves vertically. At the same time, the second buffer component can limit the moving distance of the second driving member, thereby avoiding the risk of collision caused by excessive downward movement of the first driving member and the bit.

[0023] Optionally, the second buffer component includes a support member, a movable member and a second elastic member. The support member is connected to the mounting bracket. The support member is provided with a through hole. The movable member passes through the through hole. The second elastic member is arranged on the lower side of the support member. One end of the second elastic member is connected to the support member, and the other end of the second elastic member is connected to the lower end of the movable member, enabling the movable member to move in the through hole, and the upper end of the movable member can abut against the connecting plate.

[0024] By adopting the above technical solution, the support member provides a support function. The movable member is movably disposed through the through hole of the support member. After the connecting plate abuts against the upper end of the movable member, the movable member moves downward under the pressing action of the connecting plate, so that the second elastic member can be elongated. Under the elastic action of the second elastic member, the movable member can provide a buffering function for the connecting plate to achieve the buffering and limiting functions for the connecting plate, and further achieve the buffering and limiting functions for the first driving member and the bit.

[0025] Optionally, the feeding mechanism includes a nail blowing assembly, a feeding joint and a mounting plate. The nail blowing assembly is connected to the support mechanism. One end of the mounting plate is connected to the support mechanism. The feeding joint is disposed at the other end of the mounting plate. The feeding joint is disposed below the nail blowing assembly. The nail blowing assembly is used to place screws into the feeding joint, and the feeding joint is used to place screws into the guiding member.

[0026] By adopting the above technical solution, the mounting plate is used to mount the feeding joint. The nail blowing assembly is used to place screws into the feeding joint. The feeding joint preliminarily guides the screws and conveys the screws to the guiding member to achieve continuous feeding into the guiding member.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The support mechanism provides a support function for the feeding mechanism, the pushing mechanism and the locking mechanism. The feeding mechanism is used to output screws into the guiding member. Since the guiding groove of the guiding member extends vertically and the area of the upper end of the guiding groove is larger than that of the lower end, it can adapt to the characteristic that the cross-sectional area of the head of the screw is larger than that of the screw rod. While the axis of the screw extends vertically and the head of the screw is located above the screw rod, a stable support function for the screw is achieved. And for the three-component screw including a flat washer and a spring washer, the funnel-shaped structure of the guiding groove can also easily achieve the guiding and supporting functions for the screw, thereby improving the problem that the screw is prone to tilting during locking, so as to improve the qualification rate of screw locking; After the screw is stably placed in the guiding member, the pushing mechanism drives the carrier plate to move, so that the guiding member can move to the lower part of the locking mechanism. The locking mechanism drives the screw to move to a preset position. Since the posture of the screw is corrected by the guiding member, the axis of the screw is more easily guaranteed to extend vertically. Therefore, when the locking mechanism locks the screw, the risk of difficult locking and poor locking quality caused by the screw tilt can be reduced, which helps to achieve reliable locking of the screw and improve the qualification rate of screw locking;

[0029] 2. The setting of the outer shell can, on the one hand, realize the connection between the suction component and the mounting bracket, and on the other hand, provide a accommodation space for the first elastic component; the upper end of the outer shell is connected to the mounting bracket, and the other end is movably connected to the suction component; the upper end of the suction component is connected to the first elastic component inside the outer shell, so that the suction component can move vertically relative to the outer shell under the elastic action of the first elastic component, thereby buffering the impact between the suction component and the guide member or the screw through the first buffer component, and facilitating the compensation of the height difference between the suction component and the guide member, as well as the height difference between the suction component driving the screw and the preset position, thereby improving the reliability of the device and the qualified rate of screw locking.

[0030] 3. The first driving component and the second driving component are located on different straight lines, so that after the second buffer component abuts against the connecting plate, it can, by virtue of its own elastic action, buffer the impact force when the second driving component moves vertically; at the same time, the second buffer component can limit the moving distance of the second driving component, thereby avoiding the risk of collision caused by excessive downward movement of the first driving component and the bit head.

[0038] The following is combined with the attached Figure 1 - attached Figure 4A further detailed description of the present application is provided. In this embodiment, unless otherwise clearly specified, "connection", "connection to", and "fixation" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., which can be understood according to specific circumstances.

Moreover, in the description of this embodiment, the orientation or positional relationship terms such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. Without contrary description, the orientation terms such as "inside" and "outside" used in the present application refer to the outline of the corresponding component itself.

[0040] As Figure 1 , Figure 2 and Figure 3 shown, an embodiment of the present application discloses a screw locking device (hereinafter simply referred to as "device").

[0041] As Figure 1 , Figure 2 and Figure 4 shown, the device includes a support mechanism, a feeding mechanism 1, a carrying mechanism 2, a pushing mechanism 3, and a locking mechanism 4. The device is used to lock a screw 100 in a preset position. The support mechanism (not shown in the figure) provides a supporting effect for the feeding mechanism 1, the pushing mechanism 3, and the locking mechanism 4. The specific structure of the support mechanism can be set according to needs as long as it can achieve the supporting effect on each structure. The feeding mechanism 1 is connected to the support mechanism, and the feeding mechanism 1 is used to output the screw 100 to the carrying mechanism 2.

[0042] As Figure 1 , Figure 2 and Figure 4 shown, the carrying mechanism 2 is arranged below the feeding mechanism 1, and the carrying mechanism 2 is movable so as to drive the screw 100 to move below the locking mechanism 4. The carrying mechanism 2 includes a carrying plate 21 and a guiding member 22. The guiding member 22 can be a plate-shaped, block-shaped or other shaped structure. The guiding member 22 is connected to the carrying plate 21, and the guiding member 22 is used to carry the screw 100. The guiding member 22 is provided with a guiding groove 221, and the guiding groove 221 extends in the vertical direction so that the axis of the screw 100 in the guiding groove 221 can be vertically arranged.

[0043] The upper end area of the guiding groove 221 is larger than the lower end area of the guiding groove 221. Since the diameter of the head of the screw 100 is larger than the diameter of the screw rod, the screw 100 can be clamped through the guiding groove 221. When the screw 100 enters the guiding groove 221 from above the guiding groove 221, it helps to place the head of the screw 100 above the screw rod of the screw 100. The feeding mechanism 1 is used to output the screw 100 into the guiding member 22. Since the guiding groove 221 extends vertically and the upper end area of the guiding groove 221 is larger than the lower end area, it can adapt to the characteristic that the cross-sectional area of the head of the screw 100 is larger than the cross-sectional area of the screw rod of the screw 100, so that while the axis of the screw 100 extends vertically and the head of the screw 100 is located above the screw rod, a stable supporting effect on the screw 100 is achieved. The specific structure of the guiding groove 221 can be adjusted as needed; in this embodiment, the upper end of the guiding groove 221 is a large-diameter cylinder, the middle part is a funnel shape, and the lower end is a small-diameter cylinder, which are mutually connected to form a receiving space for the screw 100. The flat washer and the spring washer can be placed on the funnel-shaped middle part. The head of the screw 100 is located above the flat washer and the spring washer, and the screw rod of the screw 100 is located at the small-diameter cylinder, so that the screw 100 is vertically arranged. For the three-component screw including the flat washer and the spring washer, the funnel-shaped structure of the guiding groove 221 can also easily achieve the guiding and supporting effects on the screw 100, thereby improving the problem that the screw 100 is prone to tilting during locking, keeping the posture of the screw 100 balanced, and further improving the qualification rate of the screw 100 locking.

[0044] As Figure 1 , Figure 2 and Figure 4 shown, the fixed end of the pushing mechanism 3 is connected to the supporting mechanism, and the movable end of the pushing mechanism 3 is connected to the bearing plate 21. The pushing mechanism 3 drives the bearing plate 21 to move. After the screw 100 is stably placed in the guiding member 22, the pushing mechanism 3 drives the bearing plate 21 to move, so that the guiding member 22 can move below the locking mechanism 4.

[0045] The locking mechanism 4 is connected to the supporting mechanism. The locking mechanism 4 is arranged on one side of the pushing mechanism 3. The movable end of the pushing mechanism 3 is used to drive the bearing mechanism 2 to move below the locking mechanism 4, so that the locking mechanism 4 drives the screw 100 on the bearing mechanism 2 to move to a preset position and lock. By driving the screw 100 to move to a preset position through the locking mechanism 4, since the posture of the screw 100 is corrected by the guiding member 22, the axis of the screw 100 is more easily ensured to extend vertically. Therefore, when the locking mechanism 4 locks the screw 100, the risk of difficult locking and poor locking quality caused by the inclination of the screw 100 can be reduced, which helps to reliably lock the screw 100 and improve the qualification rate of the screw 100 locking.

[0046] As Figure 1 , Figure 2 and Figure 4As shown, optionally, the feeding mechanism 1 includes a nail blowing assembly, a feeding joint 11 and a mounting plate 12. The nail blowing assembly is connected to the support mechanism. One end of the mounting plate 12 is connected to the support mechanism. The feeding joint 11 is provided at the other end of the mounting plate 12 and is located below the nail blowing assembly. The nail blowing assembly is used to place the screw 100 into the feeding joint 11, and the feeding joint 11 is used to place the screw 100 into the guide member 22. The mounting plate 12 is used to mount the feeding joint 11. The nail blowing assembly is used to place the screw 100 into the feeding joint 11. The feeding joint 11 conducts preliminary guidance on the screw 100 and conveys the screw 100 to the guide member 22, realizing continuous feeding to the guide member 22. The nail blowing assembly can be an existing air blowing type screw feeder. The feeding joint 11 can be a hollow cylindrical structure, thus realizing the functions of positioning, guiding and conveying.

[0047] Optionally, the pusher mechanism 3 includes a fixing plate 31 and a telescopic member 32. The fixing plate 31 is connected to the support mechanism. The fixed end of the telescopic member 32 is connected to the fixing plate 31, and the movable end of the telescopic member 32 is connected to the bearing plate 21, enabling the bearing plate 21 to drive the guide member 22 to reciprocate between the lower part of the feeding mechanism 1 and the lower part of the locking mechanism 4. The fixing plate 31 is used to connect the fixed end of the telescopic member 32 to the support mechanism. The movable end of the telescopic member 32 drives the bearing plate 21 to move, so that the guide member 22 can move between the lower part of the feeding mechanism 1 and the lower part of the locking mechanism 4, enabling the feeding mechanism 1 and the locking mechanism 4 to be horizontally distributed and reducing the occupied area of the vertical space. Moreover, through the movement of the bearing mechanism 2, it is convenient for the locking mechanism 4 to take out the screw 100, reducing the risk of interference between the feeding mechanism 1 and the locking mechanism 4. The guide member 22 moves horizontally under the push of the pusher mechanism 3, which can reduce the risk of the screw 100 tilting during the movement of the guide member 22, contributing to improving the qualification rate of screw locking. The telescopic member 32 can be a structure such as a cylinder, a hydraulic cylinder or an electric telescopic rod that can realize telescoping. The mounting plate 12 is used to support the feeding joint 11. The mounting plate 12 can be connected to the support mechanism or the fixed end of the telescopic member 32.

[0048] Such as Figure 1 、 Figure 2 and Figure 4As shown, optionally, the locking mechanism 4 includes a moving component, a mounting bracket 41, a first driving member 42, and a bit 43. The moving component is respectively connected to the support mechanism and the mounting bracket 41, and the moving component drives the mounting bracket 41 to move. The first driving member 42 is connected to the mounting bracket 41, the bit 43 is connected to the output end of the first driving member 42, the first driving member 42 drives the bit 43 to rotate, and the bit 43 is used for locking the screw 100. The moving component is used to drive the mounting bracket 41 to move in space, so as to realize the overall movement of the mounting bracket 41, so that the locking mechanism 4 can reciprocate between above the guide member 22 and above the preset position, so that the locking mechanism 4 can take out the screw 100 from the guide member 22, and then drive the screw 100 to move to the preset position. Then, through the movement of the moving component and the rotation of the first driving member 42 driving the bit 43, the bit 43 realizes the locking of the screw 100. The moving component can be a structure that can drive the mounting bracket 41 to move in space, which can be a combination of multiple sets of sliding rails and sliders, or a robotic arm and other structures. Select a suitable existing structure according to needs. The moving component can realize necessary movements such as vertical, horizontal, and rotational movements. The first driving member 42 can be a servo motor to drive the bit 43 to rotate, provide power and torque feedback for the bit 43, and realize the screwing of the screw 100. The specific structure of the mounting bracket 41 can be set according to needs to provide a reliable supporting function.

[0049] Optionally, the locking mechanism 4 includes a suction component 44. The suction component 44 is connected to the mounting bracket 41, the suction component 44 is arranged below the bit 43, and the suction component 44 is used for sucking up the screw 100 and driving the screw 100 to move, and the bit 43 can pass through the suction component 44 to lock the screw 100. The suction component 44 is used for sucking up the screw 100 to realize the driving and moving function of the screw 100. After the suction component 44 sucks up the screw 100, the moving component drives the mounting bracket 41 to move to the preset position, places the screw 100 at the preset position, and passes the bit 43 through the suction component 44 to be able to contact the screw 100 to realize the locking of the screw 100.

[0050] As Figure 1 , Figure 2 and Figure 4As shown, optionally, the air suction assembly 44 includes an air suction pipe 442 and a vacuum driver 441. The air suction pipe 442 is hollow. The upper end of the air suction pipe 442 is connected to the mounting bracket 41, and the lower end of the air suction pipe 442 is used to pick up the screw 100. The vacuum driver 441 is communicated with the air suction pipe 442, and the vacuum driver 441 is used to form a negative pressure in the air suction pipe 442. The air suction pipe 442 is connected to the mounting bracket 41, so that it can move with the mounting bracket 41. The vacuum driver 441 forms a negative pressure environment in the hollow air suction pipe 442, so that the screw 100 can be picked up through the lower end of the air suction pipe 442, and the position conversion can be realized under the drive of the movement of the mounting bracket 41. Moreover, the hollow air suction pipe 442 can allow the bit 43 to pass through, so as to realize the locking of the screw 100 at the lower end of the air suction pipe 442; alternatively, while keeping the adsorption of the screw 100 to keep the screw 100 vertical, the bit 43 can realize the locking of the screw 100, which helps to improve the success rate of the screw 100 locking. The vacuum driver 441 can be a vacuum generator, which is used to evacuate the air suction pipe 442 to form a negative pressure environment for adsorption.

[0051] Optionally, the locking mechanism 4 includes a first buffer assembly 45. The first buffer assembly 45 includes a housing 451 and a first elastic member 452. The housing 451 is arranged above the air suction assembly 44. The upper end of the housing 451 is connected to the mounting bracket 41, and the lower end of the housing 451 is movably connected to the air suction assembly 44. The first elastic member 452 is arranged in the housing 451, and the air suction assembly 44 is connected to the first elastic member 452, so that the air suction assembly 44 can move vertically under the elastic action.

[0052] As Figure 1 、 Figure 2 and Figure 4As shown, the housing 451 can, on the one hand, connect the suction component 44 to the mounting bracket 41; on the other hand, the housing 451 provides a receiving space for the first elastic member 452. The upper end of the housing 451 is connected to the mounting bracket 41, and the other end is movably connected to the suction component 44; the upper end of the suction component 44 is connected to the first elastic member 452 inside the housing 451, so that the suction component 44 can move vertically relative to the housing 451 under the elastic action of the first elastic member 452, and thus can buffer the impact between the suction component 44 and the guide member 22 or between the suction component 44 and the screw 100 through the first buffer component 45, and can facilitate compensating for the height difference between the suction component 44 and the guide member 22, as well as the height difference between the suction component 44 driving the screw 100 to move and the preset position, thereby improving the reliability of the device and the qualified rate of the locking of the screw 100. It can be understood that a connection hole is provided at the upper end of the housing 451 for the bit 43 to extend into; since the bit 43 and the connection hole cooperate with each other, after the bit 43 extends into the housing 451, a relatively sealed state can be achieved above the suction pipe 442, so that the suction effect at the lower end of the suction pipe 442 can be optimized to drive the screw 100 to move; the diameter of the bit 43 is smaller than the inner diameter of the suction pipe 442 to ensure the reliable realization of the negative pressure environment inside the suction pipe 442.

[0053] Optionally, the locking mechanism 4 includes a second driving member 46. The fixed end of the second driving member 46 is connected to the mounting bracket 41, and the movable end of the second driving member 46 is connected to the first driving member 42. The first driving member 42 is slidably connected to the mounting bracket 41, and the second driving member 46 drives the first driving member 42 to move in the vertical direction. The second driving member 46 is used to drive the first driving member 42 to move vertically, so that by driving the bit 43 to rotate through the first driving member 42 and driving the bit 43 to move vertically through the second driving member 46, the bit 43 can accurately maintain contact with the screw 100, thereby realizing the locking of the screw 100. The second driving member 46 can be a structure such as a cylinder, a hydraulic cylinder or an electric telescopic rod that can achieve expansion and contraction.

[0054] Such as Figure 1 、 Figure 2 and Figure 4As shown, optionally, the locking mechanism 4 includes a second buffer assembly 47, and the second buffer assembly 47 is disposed on the mounting bracket 41. The movable end of the second driving member 46 is connected to the first driving member 42 through a connecting plate, so that the axes of the second driving member 46 and the first driving member 42 are on different straight lines. The second buffer assembly 47 is disposed below the connecting plate. The second buffer assembly 47 has elasticity and can abut against the connecting plate. The first driving member 42 and the second driving member 46 are on different straight lines. Thus, after the second buffer assembly 47 abuts against the connecting plate, by virtue of its own elastic action, the impact force when the second driving member 46 moves vertically can be buffered. At the same time, the second buffer assembly 47 can limit the moving distance of the second driving member 46, thereby avoiding the risk of collision caused by excessive downward movement of the first driving member 42 and the bit 43.

[0055] As Figure 1 , Figure 2 and Figure 4 As shown, optionally, the second buffer assembly 47 includes a support member 471, a movable member 472 and a second elastic member. The support member 471 is connected to the mounting bracket 41. The support member 471 is provided with a through hole, and the movable member 472 movably passes through the through hole. The second elastic member is disposed on the lower side of the support member 471. The second elastic member is sleeved on the outer periphery of the movable member 472. One end of the second elastic member is connected to the support member 471, and the other end of the second elastic member is connected to the lower end of the movable member 472, so that the movable member 472 moves in the through hole, and the upper end of the movable member 472 can abut against the connecting plate. The support member 471 provides a supporting function. The movable member 472 movably passes through the through hole of the support member 471. After the connecting plate abuts against the upper end of the movable member 472, the movable member 472 moves downward under the pressing action of the connecting plate, so that the second elastic member can be elongated. Under the elastic action of the second elastic member, the movable member 472 can provide a buffering effect on the connecting plate to achieve the buffering and limiting effects on the connecting plate, and further achieve the buffering and limiting effects on the first driving member 42 and the bit 43. The support member 471 can be a plate-like or block-like structure, and the movable member 472 is a rod-like structure. Both the first elastic member 452 and the second elastic member can be springs, and their specific dimensions, models and other parameters are selected according to needs.

[0056] It can be understood that the device further includes necessary structures for functions such as connection, support, drive, limit, avoidance and control, so that the device can operate normally. Parameters such as the shape, size, material and setting quantity of each part of the device can be determined according to needs, as long as the corresponding functions can be achieved.

[0057] The implementation principle of a screw locking device according to an embodiment of the present application is as follows: The nail blowing assembly places the screw 100 in the feeding joint 11, and after preliminary guiding through the feeding joint 11, it is input into the guiding groove 221; the funnel-shaped structure of the guiding groove 221 can further guide the screw 100 and reduce the risk of the screw 100 tilting; the movable end of the telescopic member 32 drives the guiding member 22 to move below the locking mechanism 4, and the moving assembly moves downward. At the same time, the second driving member 46 can also move downward so that the suction assembly 44 can suck up the screw 100. Since the screw 100 extends vertically, it is easy to be sucked up, and the posture after being sucked up is easy to align with the preset position, which helps to improve the qualification rate of the screw 100 locking; subsequently, the suction assembly 44 drives the screw 100 to move to the preset position under the drive of the moving assembly. At this time, the screw 100 is located at the preset position, and the second driving member 46 drives the first driving member 42 to move downward, and the first driving member 42 drives the bit 43 to rotate to lock the screw 100 at the preset position.

[0058] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
