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

[0058] In the field of aerospace, for example, automatic installation of fasteners, the circumferential butt joint cabin inner wall plate area of the civil aircraft fuselage barrel segment has strict quality requirements for fastener installation process. In assembly, the most representative connecting parts are high lock bolts. At present, in the installation process, the taking of high lock nuts 100 is all manual operation, but manual operation is difficult in some positions, and the number of high lock nuts 100 of the aircraft cabin inner wall plate is huge, which inevitably leads to high labor intensity of workers and low assembly efficiency, which cannot meet the needs of modern manufacturing. If an industrial robot is used for automatic feeding and discharging of high lock nuts 100, the reachability requirement of the industrial robot for the aircraft cabin working environment needs to be met, which is difficult to implement.

[0059] Therefore, the present embodiment provides a high lock nut feeding and discharging device for automatic feeding and discharging of high lock nuts 100 to meet the subsequent high-efficiency and stable automatic assembly requirements of high lock nuts 100, and also meets the special requirements of miniaturization and light weight of process equipment in the aircraft cabin working environment.

[0060] Specifically, as Figure 1As shown, the high-lock nut feeding and discharging device comprises a feeding hopper 10, a sliding rail 20, a feeding assembly 30 and a discharging assembly 40. The feeding hopper 10 contains a plurality of high-lock nuts 100. The sliding rail 20 is located at one side of the feeding hopper 10 and is provided with a chute 21 extending in a preset direction. The feeding assembly 30 is configured to move the high-lock nuts 100 in the feeding hopper 10 into the chute 21. The discharging assembly 40 is provided with a limiting groove 421. The discharging assembly 40 is arranged at the end of the sliding rail 20, and the limiting groove 421 is in communication with the chute 21. The sliding rail 20 can sequentially convey each high-lock nut 100 in the chute 21 into the limiting groove 421. The discharging assembly 40 is configured to expose the sleeve 101 in the middle of the high-lock nut 100 above the limiting groove 421. The preset direction is the X-axis direction as shown in Figure 1 , that is, the linear direction in which the high-lock nuts 100 are transmitted on the sliding rail 20.

[0061] In operation, the feeding assembly 30 first moves the high-lock nuts 100 in the feeding hopper 10 into the chute 21 of the sliding rail 20. The high-lock nuts 100 are automatically arranged in a row in the chute 21. Then, the sliding rail 20 sequentially conveys each high-lock nut 100 in the chute 21 into the limiting groove 421. The limiting groove 421 contains one high-lock nut 100 at a time. Subsequently, the discharging assembly 40 exposes the sleeve 101 in the middle of the high-lock nut 100 above the limiting groove 421, so that the sleeve 101 is grabbed by a taking device to take away the high-lock nut 100 for subsequent assembly. Therefore, the high-lock nut feeding and discharging device can realize efficient and automatic feeding and discharging of the high-lock nuts 100, save labor, and improve assembly efficiency. The taking device is a mechanical arm end driving a taking mechanism, which can automatically grab the sleeve 101 in the middle of the high-lock nut 100. The high-lock nut feeding and discharging device provided in the embodiment has compact structure design and good stability. Compared with an industrial robot, it can expand the moving range, help to improve the operation efficiency, and is easy to implement, meeting the special needs of miniaturization and light weight of process equipment in the aircraft cabin working environment.

[0062] Further, as shown in Figure 1 and Figure 2As shown, the feeding assembly 30 comprises a feeding push plate 31 and a feeding driving component 32. The side of the feeding hopper 10 close to the slide rail 20 is a slope 11 arranged from bottom to top and inclined to the slide rail 20. The side of the bottom of the feeding hopper 10 close to the slope 11 is provided with a socket 12 through which the feeding push plate 31 is inserted and arranged close to the slope 11. The output end of the feeding driving component 32 is connected with the feeding push plate 31. The feeding driving component 32 can drive the feeding push plate 31 to reciprocatingly move up and down along the slope 11, so as to push the high-lock nuts 100 in the feeding hopper 10 into the slide groove 21. The two opposite sides of the feeding hopper 10 along the X-axis direction and the two opposite sides of the feeding push plate 31 along the X-axis direction can be slidably matched through the slide block guide rail, so as to guide the sliding of the feeding push plate 31.

[0063] As shown, Figure 1 The several high-lock nuts 100 in the feeding hopper 10 are all stacked at the position close to the feeding push plate 31. As shown, Figure 2 At this time, the feeding push plate 31 is located at the lowest position of the sliding and just blocks the socket 12. In this state, the feeding driving component 32 drives the feeding push plate 31 to slide upward along the slope 11 of the feeding hopper 10. In the process of sliding along the slope 11, the top edge of the feeding push plate 31 can push the random number of high-lock nuts 100 to rise, until the feeding push plate 31 rises to the highest position as shown, Figure 4 The feeding driving component 32 stops driving. At this time, the top edge of the feeding push plate 31 is slightly higher than the top edge of the slope 11. Due to the height difference, the high-lock nuts 100 fall into the slide groove 21. The feeding push plate 31 reciprocatingly moves up and down, so as to realize the automatic feeding of the high-lock nuts 100.

[0064] Specifically, as shown, Figure 2 The feeding driving component 32 comprises a feeding motor 321, a lifting rod 322, a slide block 323 and a guide rail 324. The feeding motor 321 is fixedly arranged and located below the feeding hopper 10. One end of the lifting rod 322 is connected with the output end of the feeding motor 321. The other end of the lifting rod 322 is hingedly connected with the slide block 323. The guide rail 324 is arranged on the feeding push plate 31 and located below the feeding hopper 10. The guide rail 324 extends along a preset direction and slidably matches with the slide block 323. When the output end of the feeding motor 321 rotates, the lifting rod 322 is driven to rotate. The lifting rod 322 drives the slide block 323 to rotate and simultaneously slide on the guide rail 324. The slide block 323 drives the guide rail 324 to drive the feeding push plate 31 to move up and down. The feeding motor 321 drives the feeding push plate 31 to repeatedly move through the above-mentioned crank slide block structure. The transmission power is large, the wear is light, the service life is long, and the feeding push plate 31 is easy to process and low in cost.

[0065] When the feeding push plate 31 is located at the lowest position, the position state among the lifting rod 322, the slide block 323 and the guide rail 324 is as shown inFigure 2 As shown in the figure, the lifting rod 322 is perpendicular to the guide rail 324 and turns to the downside of the output end of the feeding motor 321; when the feeding push plate 31 is at the highest position, the position state among the lifting rod 322, the sliding block 323 and the guide rail 324 is as shown in the figure. Figure 4 As shown in the figure, the lifting rod 322 is perpendicular to the guide rail 324 and turns to the upside of the output end of the feeding motor 321; when the feeding push plate 31 is between the lowest position and the highest position, the position state of the feeding driving component 32 is as shown in the figure. Figure 3 As shown in the figure, the lifting rod 322 is inclined relative to the guide rail 324.

[0066] As shown in the figure, Figure 1 and Figure 3 As shown in the figure, the slide rail 20 vibrates to convey the high-lock nuts 100 arranged in the slide groove 21 into the limiting groove 421 of the discharging assembly 40 one by one. Specifically, the high-lock nut feeding and discharging device further comprises a discharging motor 24 located below the slide rail 20, the output end of the discharging motor 24 is connected with a cam 25, the downside of the slide rail 20 is formed with an abutting piece 23, the abutting piece 23 is in contact with the edge of the cam 25. The discharging motor 24 can drive the cam 25 to rotate continuously at a constant speed, the cam 25 transmits the motion to the abutting piece 23 which moves close to the edge of the cam 25, so as to drive the slide rail 20 connected with the abutting piece 23 to vibrate, and the high-lock nuts 100 in the slide groove 21 will automatically slide down into the limiting groove 421. The above-mentioned setting has the advantages of simple structure, compactness, convenient design, etc., and only needs to design a proper cam 25 profile to make the slide rail 20 vibrate.

[0067] As shown in the figure, Figure 4 As shown in the figure, the high-lock nut 100 comprises a sleeve 101 and a nut head 102 and a nut tail 103 connected to the two ends of the sleeve 101 respectively, the outer diameter of the nut tail 103 is larger than that of the sleeve 101 and smaller than that of the nut head 102, and the width of the slide groove 21 is larger than the outer diameter of the nut tail 103 and smaller than the outer diameter of the nut head 102. By reasonably setting the width of the slide groove 21 according to the outer diameter of the high-lock nut 100, when the feeding push plate 31 pushes the high-lock nut 100 into the slide groove 21, the nut tail 103 and the sleeve 101 of the high-lock nut 100 directly fall into the slide groove 21, while the nut head 102 abuts against the upper surface of the slide rail 20, so that the high-lock nut 100 is in a vertical placement state and is automatically arranged in a row, and then slides out of the slide groove 21 one by one. The above-mentioned setting can automatically correct the posture of the high-lock nut 100 during the feeding process, improves the feeding efficiency, and has the advantages of simple structure, convenient design, etc., without the need of using automatic equipment to correct the posture, and low cost.

[0068] In an optional embodiment, as shown in the figure, Figure 1 and Figure 2As shown, the high-lock nut feeding and discharging device further comprises a recovery track 90, which is obliquely arranged and slightly higher than the slide rail 20. The recovery track 90 is provided with a stacking return groove 91, one end of which is in communication with the slide groove 21, and the other end of which is in communication with the feeding hopper 10. The stacking return groove 91 is used to recover the high-lock nuts 100 stacked in the slide groove 21 into the feeding hopper 10. Under normal circumstances, the high-lock nuts 100 are automatically arranged in a row in the slide groove 21 as the feeding push plate 31 continuously pushes the material. However, during the feeding process, the high-lock nuts 100 may be stacked on the upper side of the original row of high-lock nuts 100. When the high-lock nuts 100 are stacked, under the vibration of the slide rail 20, the stacked high-lock nuts 100 will automatically return to the feeding hopper 10 through the stacking return groove 91 to wait for sorting and feeding, thereby avoiding the high-lock nuts 100 from falling off the slide rail 20 due to stacking.

[0069] In an optional embodiment, as shown in Figure 2 The slide rail 20 is provided with a baffle 22 on the side away from the feeding hopper 10. The baffle 22 has the function of blocking the high-lock nuts 100, thereby avoiding the stacked high-lock nuts 100 from falling out of the slide rail 20.

[0070] In an optional embodiment, as shown in Figure 1 The high-lock nut feeding and discharging device further comprises a proximity limiting flow sensor 50, which is arranged beside the slide rail 20 and between the feeding hopper 10 and the discharging assembly 40. The proximity limiting flow sensor 50 is in communication connection with the feeding motor 321 through a control module, and can detect the high-lock nuts 100. When the proximity limiting flow sensor 50 senses that the high-lock nuts 100 stop changing at this position, it indicates that the high-lock nuts 100 downstream have reached the limiting number. At this time, the proximity limiting flow sensor 50 feeds back a signal to the control module, and the control module controls the feeding motor 321 to stop working, thereby reducing the pressure of material stacking. The control module is a prior art, and any control module and electrical connection mode that can achieve the above-mentioned effect can be used, and thus will not be described here.

[0071] In an optional embodiment, as shown in Figure 5 and Figure 6As shown, the blanking assembly 40 includes a support seat 41, a limiting seat 42, two material-taking telescopic plates 43 and an elastic connecting component 44. The support seat 41 is used to support the high lock nut 100. The limiting seat 42 is located above the support seat 41 and can dock with the end of the slide rail 20. A limiting groove 421 is provided on the limiting seat 42. One end of the limiting groove 421 is open to dock and connect with the slide 21. The two material-taking telescopic plates 43 are respectively arranged on both sides of the limiting seat 42 along the width direction of the slide 21; the elastic connecting component 44 is elastically connected between the corresponding material-taking telescopic plates 43 and the support seat 41. The material-taking telescopic plates 43 can drive the limiting seat 42 to move downward relative to the support seat 41 to expose the sleeve 101 to the top of the limiting groove 421.

[0072] Combine Figure 5 When a high lock nut 100 moves from the slide groove 21 to the limiting groove 421, the high lock nut 100 stops moving. At this time, the nut tail 103 of the high lock nut 100 is supported on the support seat 41, the nut head 102 of the high lock nut 100 is exposed above the limiting groove 421, and the sleeve 101 of the high lock nut 100 is located below the limiting seat 42. When taking the high lock nut 100, the material taking device first presses down the material taking telescopic plate 43, and the material taking telescopic plate 43 overcomes the elastic force of the elastic connecting component 44 and drives the limiting seat 42 to move downward relative to the support seat 41 (such as Figure 6 As shown), at this time, the nut head 102 and the sleeve 101 of the high lock nut 100 are exposed above the limiting groove 421, so that the material picking device can clamp the sleeve 101 and remove the high lock nut 100. After the material picking device is removed, under the action of the elastic connection component 44, the material picking telescopic plate 43 drives the limiting seat 42 to reset, waiting for the next high lock nut 100 to be unloaded. Therefore, under the elastic connection of the elastic connection component 44, the material picking telescopic plate 43 can drive the limiting seat 42 to move downward relative to the support seat 41 to expose the sleeve 101 of the high lock nut 100 for easy clamping. After the high lock nut 100 is unloaded, under the action of the elastic restoring force of the elastic connection component 44, the material picking telescopic plate 43 drives the limiting seat 42 to reset. The structure is simple and the operation is convenient.

[0073] In an optional embodiment, if Figure 5 and Figure 6As shown, the elastic connecting component 44 specifically comprises a connecting piece 441 and an elastic piece 442. The connecting piece 441 is an integral structure, comprising a head portion 4411 and a rod portion 4412. One end of the rod portion 4412 penetrates the material taking telescopic plate 43 and is connected with the head portion 4411. The other end of the rod portion 4412 is fixedly connected with the support base 41, and the head portion 4411 abuts against the upper surface of the material taking telescopic plate 43. The elastic piece 442 is sleeved outside the rod portion 4412, one end of the elastic piece 442 abuts against the material taking telescopic plate 43, and the other end abuts against the support base 41. The elastic piece 442 can be a spring, and the connecting piece 441 can be a bolt which is threadedly fixedly connected with the support base 41, or the connecting piece 441 can also be weldedly fixed with the support base 41.

[0074] As shown in Figure 6 , when the material taking telescopic plate 43 is pressed down, the material taking telescopic plate 43 compresses the elastic piece 442, and the support base 41 and the connecting piece 441 are fixedly unmoved. The rod portion 4412 of the connecting piece 441 can play a certain guiding and limiting role on the elastic piece 442, so as to ensure that the elastic piece 442 only stretches and contracts along the axial direction thereof. After the pressing force is removed, under the action of the elastic piece 442, the material taking telescopic plate 43 drives the limiting seat 42 to reset, until the material taking telescopic plate 43 abuts against the lower surface of the head portion 4411 of the connecting piece 441. The head portion 4411 plays a limiting role when resetting the material taking telescopic plate 43.

[0075] In an optional embodiment, as shown in Figure 5 and Figure 6 , the high-lock nut feeding and discharging device further comprises a flow control assembly 60 and a limiting assembly 70. The flow control assembly 60 is located below the limiting groove 421 and close to the discharging assembly 40, and the limiting assembly 70 is arranged below the limiting groove 421 and between the flow control assembly 60 and the discharging assembly 40. The flow control assembly 60 can block the high-lock nuts 100 upstream from reaching the limiting assembly 70, and can ensure that only one high-lock nut 100 reaches the limiting assembly 70 each time. The limiting assembly 70 can push one high-lock nut 100 into the limiting groove 421 each time, so as to avoid two or more high-lock nuts 100 from reaching the limiting groove 421 and affecting the material taking device clamping the high-lock nuts 100.

[0076] In an optional embodiment, as shown in Figure 5As shown, the flow control assembly 60 specifically comprises a flow control motor 61 and a flow control support 62 connected to the output shaft of the flow control motor 61, and the flow control support 62 comprises a plurality of flow control rods 621 radially distributed around the output end of the flow control motor 61. The flow control motor 61 can drive the flow control support 62 to rotate intermittently in the horizontal plane, so that the flow control rods 621 can block or allow one high-lock nut 100 to pass. In the present embodiment, the flow control rods 621 are arranged uniformly in four, and the space between two flow control rods 621 can only accommodate one high-lock nut 100. The flow control motor 61 drives the flow control support 62 to rotate only one quarter of a circle clockwise each time, so that one high-lock nut 100 between two flow control rods 621 reaches the limiting assembly 70, while the upstream high-lock nut 100 is blocked from reaching the limiting assembly 70, thereby avoiding two or more high-lock nuts 100 from reaching the limiting groove 421 at the same time and affecting the clamping of the high-lock nut 100 by the material taking device. In other alternative embodiments, the number of flow control rods 621 is not limited to four, and can be adaptively selected according to actual needs, which is not specifically limited here.

[0077] In an alternative embodiment, as shown in Figure 7 , the limiting assembly 70 specifically comprises a limiting motor 71 and a limiting support 72 connected to the output shaft of the limiting motor 71, and the limiting support 72 comprises a plurality of limiting rods 721 radially distributed around the output end of the limiting motor 71. The limiting motor 71 can drive the limiting support 72 to rotate intermittently in the horizontal plane, so that the limiting rods 721 can push one high-lock nut 100 into the limiting groove 421. In the present embodiment, referring to Figure 7 , the limiting rods 721 are arranged uniformly in four, and the limiting motor 71 drives the limiting support 72 to rotate only one quarter of a circle counterclockwise each time, so that one of the limiting rods 721 pushes one high-lock nut 100 previously released by the flow control assembly 60 into the limiting groove 421, while the other limiting rod 721 blocks one high-lock nut 100 subsequently released by the flow control assembly 60. In this way, only one high-lock nut 100 enters the limiting groove 421 each time, thereby avoiding two or more high-lock nuts 100 from reaching the limiting groove 421 at the same time and affecting the clamping of the high-lock nut 100 by the material taking device. In other alternative embodiments, the number of limiting rods 721 is not limited to four, and can be adaptively selected according to actual needs, which is not specifically limited here.

[0078] It can be understood that, as shown in Figure 7As shown, at this time, one of the limiting rods 721 has pushed one high-lock nut 100 to the limiting groove 421, and the limiting rod 721 is located below the material taking telescopic plate 43. If the material taking device presses down the material taking telescopic plate 43 to perform the material taking operation at this time, the material taking telescopic plate 43 and the limiting seat 42 will interfere with the limiting rod 721 during the downward movement, causing the downward movement to be blocked.

[0079] To solve the above problems, in an optional embodiment, as shown in the figure, Figure 6 The high-lock nut feeding and discharging device further comprises a proximity limiting sensor 80 located beside the discharging assembly 40 and in communication connection with the limiting motor 71 through the control module. The proximity limiting sensor 80 is used to detect whether there is a high-lock nut 100 in the limiting groove 421. When the proximity limiting sensor 80 senses that there is a high-lock nut 100 in the limiting groove 421, the proximity limiting sensor 80 will feed back a signal to the control module at this time, and the control module controls the limiting motor 71 to continue to rotate counterclockwise by a certain angle, so that the limiting rod 721 rotates from Figure 7 to a position parallel to the material taking telescopic plate 43 in Figure 6 At this time, the limiting rod 721 is located outside the material taking telescopic plate 43, that is, in a position avoiding the material taking telescopic plate 43. Then the material taking device presses down the material taking telescopic plate 43 to perform the material taking operation, thereby avoiding the interference problem between the limiting rod 721 and the material taking telescopic plate 43 and the limiting seat 42.

[0080] As shown in the figure, Figure 6 The material taking telescopic plate 43 away from the limiting assembly 70 is connected with the support seat 41 through two elastic connecting components 44, and the material taking telescopic plate 43 close to the limiting assembly 70 is connected with the support seat 41 through only one elastic connecting component 44, so as to avoid the interference between the limiting rod 721 and the elastic connecting component 44 during the rotation.

[0081] It should be noted that the high-lock nut feeding and discharging device further comprises a workbench or a plurality of supports (not shown), and the above-mentioned feeding hopper 10, feeding motor 321, sliding rail 20, discharging motor 24, proximity current limiting sensor 50, current limiting motor 61, limiting motor 71, support seat 41 and proximity limiting sensor 80 can be fixed on the workbench or the corresponding supports.

[0082] In an optional embodiment, as shown in the figure, Figure 8 The high-lock nut feeding and discharging device further comprises an outer box 200 surrounding the entire device. The outer box 200 can protect the entire device, improve safety and aesthetics.

[0083] The working process of the high-lock nut feeding and discharging device will be described in combination with Figures 1 to 7 , which specifically includes the following steps:

[0084] 1) The feeding motor 321 drives the lifting rod 322 to rotate, the lifting rod 322 drives the sliding block 323 to rotate and slide on the guide rail 324 at the same time, the sliding block 323 drives the guide rail 324 to drive the feeding push plate 31 to slide along the inclined surface 11 of the feeding hopper 10 to the upper side, the top edge of the feeding push plate 31 can push the random number of high lock nuts 100 to rise, until the feeding push plate 31 rises to the highest position, the high lock nuts 100 fall into the chute 21, the feeding push plate 31 reciprocates to realize the automatic feeding of each high lock nut 100;

[0085] 2) The high lock nuts 100 are automatically aligned in the chute 21 and arranged in a row, when the high lock nuts 100 are accumulated, the accumulated high lock nuts 100 will be automatically returned to the feeding hopper 10 through the stacking return groove 91 to wait for sorting and feeding;

[0086] 3) Under the drive of the discharging motor 24, the slide rail 20 vibrates, and the high lock nuts 100 in the chute 21 will be automatically transported downstream;

[0087] 4) When the proximity flow limiting sensor 50 senses that the high lock nuts 100 stay in this position without change, it means that the number of high lock nuts 100 downstream has reached the limit, at this time the proximity flow limiting sensor 50 feeds back the signal to the control module, and the control module controls the feeding motor 321 to stop working, reducing the pressure of material accumulation;

[0088] 5) The flow control motor 61 drives the flow control bracket 62 to rotate only a quarter of a circle clockwise each time, so as to ensure that only one high lock nut 100 reaches the limiting assembly 70, while blocking the high lock nuts 100 upstream from reaching the limiting assembly 70, the limiting motor 71 drives the limiting bracket 72 to rotate only a quarter of a circle counterclockwise each time, so as to push only one high lock nut 100 into the limiting groove 421;

[0089] 6) When the proximity limiting sensor 80 senses that there is a high lock nut 100 in the limiting groove 421, the proximity limiting sensor 80 feeds back the signal to the control module, and the control module controls the limiting motor 71 to continue to rotate counterclockwise by a certain angle, so that the limiting rod 721 rotates to a position parallel to the material taking telescopic plate 43 to avoid the material taking telescopic plate 43;

[0090] 7) After that, the taking device presses down the taking telescopic plate 43, the taking telescopic plate 43 compresses the elastic element 442 and drives the limiting seat 42 to move downwards relative to the support seat 41, so that the nut head 102 and the sleeve 101 of the high-lock nut 100 are exposed above the limiting groove 421, then the taking device clamps the sleeve 101 to take away the high-lock nut 100. After the taking device is removed, under the action of the elastic element 442, the taking telescopic plate 43 drives the limiting seat 42 to reset, and waits for the next high-lock nut 100 to be discharged.

[0091] In summary, the high-lock nut feeding and discharging device can realize automatic feeding, automatic posture adjustment, automatic conveying, automatic returning of accumulated materials, automatic flow control, material in-place control, taking telescopic control, can save labor, and improve assembly efficiency, and has compact overall structure design, good stability, and can expand the moving range compared with the industrial robot, and meets the special needs of the aircraft cabin operation environment for process equipment miniaturization and light weight.
