Description

Technical Field

[0001] This invention belongs to the field of screw handling technology, and specifically relates to a screw handling device. Background Technology

[0002] Screws are indispensable connecting parts in mechanical equipment. During the production and assembly process, operators usually grab screws by hand to connect the equipment. However, grabbing screws by hand can lead to taking too many or too few screws. Taking too many screws can cause them to fall out of one's hand, while taking too few screws will increase the number of times one has to pick them up, thus causing inconvenience. Summary of the Invention

[0003] Therefore, the present invention provides a screw-taking device that can solve the technical problem that operators grabbing screws by hand can result in taking too many or too few screws, thus causing inconvenience.

[0004] To address the aforementioned problems, the present invention provides a screw handling device, comprising a screw arranging mechanism and a screw number cutting mechanism. The screw arranging mechanism has an arrangement groove formed therein for screws to be arranged sequentially. A screw outlet is formed on one side of the arrangement groove. The screw number cutting mechanism includes a separating component and has a fixed-number cutting state. When the screw number cutting mechanism is in the fixed-number cutting state, the separating component separates all the screws arranged in the arrangement groove into two segments.

[0005] In some embodiments, the screw number cutting mechanism further includes a blocking component, and the screw number cutting mechanism also has an initial blocking state; when the screw number cutting mechanism is in the initial blocking state, the blocking component blocks the screw outlet, and the separating component releases the separation of all screws arranged in the arrangement slot; when the screw number cutting mechanism is in the number cutting state, the blocking component releases the blockage of the screw outlet.

[0006] In some embodiments, the width of the groove is greater than the diameter of the screw shank and less than the diameter of the screw head; and / or, the groove extends obliquely from top to bottom.

[0007] In some embodiments, the width of the arrangement groove can be adjusted; and / or, the screw fixed-number cutting mechanism further includes a first sliding body, the separating member is assembled on the first sliding body, and the position of the separating member on the first sliding body can be adjusted to adjust the distance between the separating member and the screw outlet.

[0008] In some embodiments, a screw separating and sorting component is provided on the side of the screw aligning mechanism away from the screw number cutting mechanism, the screw separating and sorting component being used to separate the screws and allow them to enter the aligning slots in sequence.

[0009] In some embodiments, the screw sorting component includes a bottom wall and a first side wall and a second side wall connected to the bottom wall. The bottom wall extends obliquely from top to bottom. The distance between the first side wall and the second side wall gradually decreases in the direction close to the screw sorting mechanism. A first opening is formed between the side of the first side wall close to the screw sorting mechanism and the side of the second side wall close to the screw sorting mechanism. A screw inlet is formed on the side of the sorting groove away from the screw outlet, and the screw inlet is connected to the first opening.

[0010] In some embodiments, there is a height difference between the first opening and the arrangement groove; and / or, the angle formed between the bottom wall and the horizontal plane is α, where 20°≤α≤30°.

[0011] In some embodiments, the screw separating and sorting component further includes a third sidewall and a fourth sidewall connected to the bottom wall. The third sidewall and the fourth sidewall are both located within the space enclosed by the bottom wall, the first sidewall, and the second sidewall. The distance between the third sidewall and the fourth sidewall gradually decreases in the direction close to the first opening. A second opening is formed between the side of the third sidewall close to the first opening and the fourth sidewall.

[0012] In some embodiments, a screw feeding mechanism is provided on the side of the screw separating and sorting component away from the screw number cutting mechanism, the screw feeding mechanism being used to feed screws into the screw separating and sorting component.

[0013] In some embodiments, the screw feeding mechanism includes a screw receiving frame and a top plate. The screw receiving frame is inclined from top to bottom, and a channel is formed on the bottom wall of the screw receiving frame. The top plate can pass through the channel to push the screws contained in the screw receiving frame into the screw sorting component.

[0014] The screw-retrieving device provided by this invention has the following beneficial effects: Since the separating component of the screw fixed-number cutting mechanism can separate all the screws arranged in the arrangement slot of the screw aligning mechanism into two sections, the number of screws in this section from the separating component to the screw outlet is always a fixed number. When all the screws in this section are taken each time, a fixed number of screws can be taken, so that the phenomenon of taking too many or too few screws will not occur.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0020] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0021] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0022] See also Figures 1 to 12 As shown, according to an embodiment of the present invention, a screw handling device is provided, including a screw arranging mechanism 1 and a screw fixed-number cutting mechanism 2. The screw arranging mechanism 1 has an arrangement groove 3 formed therein, which is used to arrange screws sequentially. A screw outlet is formed on one side of the arrangement groove 3. The screw fixed-number cutting mechanism 2 includes a separating member 21. The screw fixed-number cutting mechanism 2 has a fixed-number cutting state. When the screw fixed-number cutting mechanism 2 is in the fixed-number cutting state, the separating member 21 separates all the screws arranged in the arrangement groove 3 into two segments.

[0023] In this technical solution, since the separating component 21 of the screw fixed-number cutting mechanism 2 can separate all the screws arranged in the arrangement groove 3 of the screw arranging mechanism 1 into two sections, the number of screws in this section from the separating component 21 to the screw outlet is always a fixed number. When all the screws in this section are taken each time, a fixed number of screws can be taken, so that the phenomenon of taking too many or too few screws will not occur.

[0024] See also Figure 1 and Figure 12 As shown, the screw fixed-number cutting mechanism 2 also includes a blocking component 22, and the screw fixed-number cutting mechanism 2 also has an initial blocking state; when the screw fixed-number cutting mechanism 2 is in the initial blocking state, the blocking component 22 blocks the screw outlet, and the separating component 21 releases the separation of all screws arranged in the arrangement groove 3; when the screw fixed-number cutting mechanism 2 is in the fixed-number cutting state, the blocking component 22 releases the blockage of the screw outlet.

[0025] In this embodiment, when the screw fixed-number cutting mechanism 2 is in the initial blocking state, the blocking component 22 blocks the screw outlet, so the screw will not fall out of the screw outlet. At the same time, the separating component 21 does not contact the screws in the arrangement groove 3, so the separating component 21 will not separate the screws arranged in the arrangement groove 3. When the screw fixed-number cutting mechanism 2 is in the fixed-number cutting state, the blocking component 22 releases the blockage on the screw outlet, so the screw can fall out of the screw outlet and be taken out. At the same time, the separating component 21 separates all the screws arranged in the arrangement groove 3 into two segments. Only the screws in the segment from the separating component 21 to the screw outlet will fall out of the screw outlet, thus realizing the fixed-number taking of screws.

[0026] In one specific implementation, the width of the arrangement groove 3 is greater than the diameter of the screw shank and less than the diameter of the screw head. This allows the screws to be arranged neatly in a row within the arrangement groove 3, facilitating calculation and fixed-number screw usage. At the same time, the screw head is exposed outside the arrangement groove 3, which also facilitates the separation component 21 to contact the screw outside the arrangement groove 3 and separate all the screws arranged in the arrangement groove 3 into two segments.

[0027] See also Figure 1 and Figure 2 As shown, the arrangement groove 3 extends obliquely from top to bottom, so that after the blocking component 22 releases the blockage on the screw outlet, the screw can automatically fall out of the screw outlet under the action of gravity and be used.

[0028] As a specific implementation method, the width of the arrangement slot 3 can be adjusted so that the arrangement slot 3 can adapt to screws of different diameters, thereby achieving neat arrangement and fixed number of screws of different specifications.

[0029] See also Figure 1 and Figure 2As shown, the screw alignment mechanism includes a first guide rail 11, a second guide rail 12, and a first guide plate 13. Both the first guide rail 11 and the second guide rail 12 are assembled on the first guide plate 13. The first guide rail 11 includes a first side plate, and the second guide rail 12 includes a second side plate. The first and second side plates are spaced apart on the first guide plate 13, and the first side plate, second side plate, and first guide plate 13 together form an alignment groove 3. Furthermore, the first guide rail 11 also includes a first base plate connected to the bottom of the first side plate, and the second guide rail 12 also includes a second base plate connected to the bottom of the second side plate. The first base plate has a first oblong hole 7, and the second base plate has a second oblong hole 8. The first guide plate 13 has a first threaded hole and a second threaded hole. A first fastener passes through the first oblong hole 7 and is threaded into the first threaded hole, and a second fastener passes through the second oblong hole 8 and is threaded into the second threaded hole. Loosening the first and second fasteners allows the positions of the first guide rail 11 and the second guide rail 12 on the first guide plate 13 to be adjusted, thereby allowing the width of the arrangement groove 3 to be adjusted. Tightening the first and second fasteners fixes the positions of the first guide rail 11 and the second guide rail 12 on the first guide plate 13, thereby fixing the adjusted width of the arrangement groove 3.

[0030] See also Figure 1 , Figures 4 to 6 and Figure 12As shown, the screw fixed-number cutting mechanism 2 also includes a first sliding body 23, a first guide post 24, a rotating body 25, a second guide post 26, and a spring 27. The first guide post 24 is arranged in the vertical direction, and the first sliding body 23 is fitted onto the first guide post 24 and can slide up and down along the first guide post 24. A separating component 21 is assembled on the first sliding body 23. The second guide post 26 is arranged in the horizontal direction, and the rotating body 25 is fitted onto the second guide post 26 and can rotate around the circumference of the second guide post 26. A blocking component 22 is assembled on the rotating body 25. One end of the spring 27 is fixed to the rotating body 25, and the other end of the spring 27 is fixed to the second guide post 26. The rotating body 25 abuts against the first sliding body 23. It should be noted that when the screw quantity cutting mechanism 2 is not operated, under the action of spring 27, the screw quantity cutting mechanism 2 is in the initial blocking state. The blocking component 22 is placed horizontally at the screw outlet of the arrangement groove 3 to prevent the screw from falling out, and the separating component 21 is located above the arrangement groove 3 and does not contact the screw in the arrangement groove 3. A pressing surface 28 is formed on the rotating body 25. The pressing surface 28 is located below the screw outlet. When the operator's back of hand touches the pressing surface 28 and presses down, the rotating body 25 will rotate downward around the second guide post 26. The spring 27 is stretched, the blocking component 22 moves away from the screw outlet and releases the obstruction of the screw outlet. The screw in the arrangement groove 3 automatically falls into the operator's palm. Simultaneously, because the rotating body 25 rotates downward around the second guide post 26, the contact between the rotating body 25 and the first sliding body 23 is temporarily eliminated. Therefore, the first sliding body 23 slides downward along the first guide post 24 under the action of gravity, thereby driving the separating component 21 to move downward and separating all the screws arranged in the arrangement groove 3 into two segments. This allows the screws in the segment from the separating component 21 to the screw outlet to automatically fall into the operator's palm, thus achieving a fixed number of screws to be picked up. The blocking component 22 can be a bolt threaded onto the rotating body 25. For operational comfort, a sponge can be laid on the pressing surface 28.

[0031] In one specific implementation, the position of the separating component 21 on the first sliding body 23 can be adjusted to regulate the distance between the separating component 21 and the screw outlet. The distance between the separating component 21 and the screw outlet represents the number of screws taken. When this distance changes, it indicates that the number of fixed-quantity screws taken can be adjusted, thus adapting to the different screw requirements of different production assembly stages. A slide rail can be formed on the first sliding body 23. The separating component 21 is assembled on the slide rail and can slide along the slide rail to adjust its position. By using a locking member with a threaded connection through the separating component 21 and abutting against the slide rail, the position of the separating component 21 can be fixed after adjustment.

[0032] See also Figure 1 , Figure 7 , Figure 8 and Figure 12 As shown, a screw separating and sorting component 4 is provided on the side of the screw aligning mechanism 1 away from the screw number cutting mechanism 2. The screw separating and sorting component 4 is used to separate the screws and let them enter the aligning groove 3 in sequence.

[0033] In this technical solution, since the screw separating and sorting component 4 enables the screws to enter the arrangement slot 3 separately and sequentially, the setting of the screw separating and sorting component 4 can realize that the screws are automatically and neatly arranged in the arrangement slot 3.

[0034] See also Figure 1 , Figure 7 , Figure 8 and Figure 12 As shown, the screw sorting component 4 includes a bottom wall 41 and a first side wall 42 and a second side wall 43 connected to the bottom wall 41. The bottom wall 41 extends obliquely from top to bottom. The gap between the first side wall 42 and the second side wall 43 gradually decreases in the direction close to the screw sorting mechanism 1. A first opening is formed between the side of the first side wall 42 close to the screw sorting mechanism 1 and the side of the second side wall 43 close to the screw sorting mechanism 1. A screw inlet is formed on the side of the sorting groove 3 away from the screw outlet. The screw inlet is connected to the first opening.

[0035] In this embodiment, because the gap between the first sidewall 42 and the second sidewall 43 gradually decreases in the direction approaching the screw aligning mechanism 1, the space enclosed by the first sidewall 42, the second sidewall 43, and the bottom wall 41 exhibits a narrowing effect in the direction approaching the screw aligning mechanism 1. Furthermore, because the bottom wall 41 extends obliquely from top to bottom, when a certain number of screws fall into the screw separating and sorting component 4, under the action of gravity, each screw will automatically slide downwards. Combined with the narrowing effect, this causes the screws to disperse and sequentially enter the aligning groove 3 from the first opening, thereby enabling the screw separating and sorting component 4 to separate and sequentially enter the aligning groove 3.

[0036] In one specific implementation, there is a height difference between the first opening and the arrangement groove 3. When the screw slides downward in the screw separating and sorting component 4, the head of the screw faces upward and the free end of the screw shank faces downward. The height difference between the first opening and the arrangement groove 3 causes the screw to enter the arrangement groove 3 at a large angle. Combined with the impact force when sliding down, the screws will eventually stand upright in the arrangement groove 3, with the head of the screw facing upward and protruding outside the arrangement groove 3.

[0037] In one specific implementation, the angle between the bottom wall 41 of the screw separating and sorting component 4 and the horizontal plane is α. When 20°≤α≤30° is satisfied, the screw separating and sorting component 4 will have an appropriate tilt angle. This allows the screws to slide down the screw separating and sorting component 4 with a certain speed to stand upright in the arrangement groove 3, while also preventing the screws from sliding down too fast and flying out of the arrangement groove 3. It should be noted that the tilt angle of the arrangement groove 3 is approximately the same as the tilt angle of the screw separating and sorting component 4. The first guide rail component 11 also includes a first protective body that connects to the top of the first side plate. The first protective body extends from the screw inlet to the screw outlet. The second guide rail component 12 also includes a second protective body that connects to the top of the second side plate. The second protective body also extends from the screw inlet to the screw outlet. The first and second protective bodies are used to prevent the screws sliding out of the screw separating and sorting component 4 from flying out of the arrangement groove 3 due to excessive speed.

[0038] See also Figure 1 , Figure 7 , Figure 8 and Figure 12 As shown, the screw separating and sorting component 4 also includes a third side wall 44 and a fourth side wall 45 connected to the bottom wall 41. The third side wall 44 and the fourth side wall 45 are both located within the space enclosed by the bottom wall 41, the first side wall 42, and the second side wall 43. The distance between the third side wall 44 and the fourth side wall 45 gradually decreases in the direction close to the first opening. A second opening is formed between the side of the third side wall 44 close to the first opening and the fourth side wall 45.

[0039] In this technical solution, the space enclosed by the third side wall 44, the fourth side wall 45 and the bottom wall 41 also has a narrowing effect in the direction close to the screw sorting mechanism 1. This allows the screws that fall into the screw sorting component 4 to be automatically sorted twice, thus making the automatic sorting effect of the screws better.

[0040] See also Figure 1 and Figure 12 As shown, a screw feeding mechanism 5 is provided on the side of the screw separating and sorting component 4 away from the screw fixed number cutting mechanism 2. The screw feeding mechanism 5 is used to feed screws into the screw separating and sorting component 4 to achieve automatic feeding.

[0041] See also Figure 1 , Figures 8 to 10 and Figure 12As shown, the screw feeding mechanism 5 includes a screw receiving frame 51 and a top plate 52. The screw receiving frame 51 is inclined from top to bottom, and the inclination angle of the screw receiving frame 51 is approximately the same as the inclination angle of the screw separating and sorting component 4. A channel is constructed on the bottom wall of the screw receiving frame 51, and the top plate 52 can pass through the channel to push the screws contained in the screw receiving frame 51 into the screw separating and sorting component 4. The screw receiving frame 51 can be a plastic basket, and the top plate 52 can be a PVC sheet.

[0042] In this technical solution, the channel is located near the front of the screw receiving frame 51. The screw receiving frame 51 is inclined from top to bottom, causing the screws to gather at the front of the screw receiving frame 51 under the action of gravity. The width of the channel is smaller than the diameter of the screw head, so there is no need to worry about the screws falling out of the channel. When the top plate 52 passes through the channel on the screw receiving frame 51, it can push the screws out of the screw receiving frame 51. Since the screw receiving frame 51 is inclined from top to bottom, the pushed-out screws will be thrown upwards and then fall downwards at an angle, thus enabling the screws to automatically move forward and enter the screw separating and sorting component 4. Moreover, the pushed-out screws will also disperse in the air, which makes the screws entering the screw separating and sorting component 4 already in a dispersed state, thereby also helping to separate and sort the screws in the screw separating and sorting component 4. Preferably, the top plate 52 is perpendicular to the bottom wall of the screw receiving frame 51.

[0043] In one specific implementation, the screw feeding mechanism 5 further includes an operating handle 53, a third guide post 54, a first pulley 55, a rope 56, a first support post 57, a second pulley 58, a second sliding body 59, and a fourth guide post 60. The third guide post 54 is arranged in the vertical direction. The operating handle 53 is fitted onto the third guide post 54 and can slide up and down along the third guide post 54. The first pulley 55 is fixed onto the operating handle 53. The first support post 57 is arranged in the vertical direction. The second pulley 58 is fixed onto the first support post 57. The fourth guide post 60 extends obliquely upward. The second sliding body 59 is fitted onto the fourth guide post 60 and can slide up and down along the fourth guide post 60. The top plate 52 is assembled onto the second sliding body 59. One end of the rope 56 is connected to the operating handle 53, and then the rope 56 passes through the first pulley 55 and the second pulley 58 in sequence before its other end is connected to the second sliding body 59. When the operator presses down on the operating handle 53, the rope 56 pulls the second sliding body 59 to slide obliquely upward on the fourth guide post 60. This allows the second sliding body 59 to drive the top plate 52 through the channel of the screw receiving frame 51, thus pushing out the screws inside the screw receiving frame 51. When the operator releases the pressure of the operating handle 53, the second sliding body 59 slides down along the fourth guide post 60 under its own weight, and the rope 56 pulls the operating handle 53 back to its original position.

[0044] It should be noted that the screw handling device also includes a frame 6, which is mainly assembled using LCIA third-generation lean pipes. The screw aligning mechanism 1, the screw fixed-number cutting mechanism 2, the screw separating and sorting component 4, and the screw feeding mechanism 5 are all assembled on the frame 6. Specifically, the frame 6 includes a frame body 61, a second guide plate 62, a third guide plate 63, a second support column, a third support column, and a fourth support column. The second, third, and fourth support columns are all assembled on the frame body 61. The second guide plate 62 is assembled on the second support column, and the third guide plate 63 is assembled on the third support column. The first guide plate 13 of the screw aligning mechanism 1 is assembled on the fourth support column. The screw aligning mechanism is assembled on the frame body 61 via the first guide column 24 and the second guide column 26. The screw feeding mechanism 5 is assembled on the frame body 61 via the third guide column 54, the first support column 57, and the fourth guide column 60. The screw receiving frame 51 of the screw feeding mechanism 5 is assembled on the third guide plate 63, and the screw separating and sorting component 4 is assembled on the second guide plate 62. The first guide column 24, the second guide column 26, the third guide column 54, the fourth guide column 60, the first support column, the second support column, the third support column, and the fourth support column can all be made of lean tubing. It is understandable that the screw picking device of this application mainly relies on the linkage effect of various mechanisms, without the need for other electricity and related procedures, thus resulting in low cost, convenient operation, and strong versatility. According to a rough comparison, it saves more than 80% of costs compared with other automated equipment.
