Description

Technical Field

[0001] The invention relates to the technical field of workshop production equipment, and in particular to a shearing device for a bumper assembly connecting rod. Background Art

[0002] At present, many cars use left and right split bumper groups to facilitate replacement and maintenance. At the same time, in order to facilitate production and manufacturing, the left and right split bumper groups, that is, the two bumpers are connected by a connecting rod for transportation. When the robot moves the two bumpers away, the connecting rod needs to be manually cut off to separate the two bumpers. However, the method of manually cutting off the connecting rod has the problems of low production efficiency, high labor cost and high labor intensity. Some existing workshops also use cutting equipment to automatically cut the connecting rod. However, due to the limitations of its own structure, the cutting equipment can often only cut the connecting rod at a fixed position, and cannot achieve flexible adjustment of the cutting amount and maximize the cutting amount. It is often only applicable to the cutting of the connecting rod of a single model bumper group. It is inflexible to use, has poor compatibility, a narrow range of application, and a low degree of automation. Summary of the invention

[0038] The present invention provides a device for cutting off the connecting rod of a bumper group.

[0039] As Figures 1 to 7 shown, the bumper group 200 includes two bumpers 201, and the two bumpers 201 are connected by a connecting rod 202. The device 100 for cutting off the connecting rod 202 of the bumper group 200 in this embodiment includes a frame 10, a material transporting mechanism 20, and a cutting-off mechanism 30. Among them, the material transporting mechanism 20 includes two material transporting frames 21 arranged at intervals in the first direction, and the two bumpers 201 are respectively carried on the two material transporting frames 21. The two material transporting frames 21 are used to synchronously transport the bumper group 200 in the second direction. Each material transporting frame 21 is slidably installed on the frame 10, and the two material transporting frames 21 can move toward or away from each other along the first direction relative to the frame 10; the first direction is perpendicular to the second direction; the cutting-off mechanism 30 includes two support frames 31, and each support frame 31 is slidably installed on the frame 10, and a pneumatic scissor 32 for cutting off the connecting rod 202 is installed on each support frame 31. The two support frames 31 and the two material transporting frames 21 are arranged in one-to-one linkage, so that the two support frames 31 can move toward or away from each other along the first direction relative to the frame 10 following the two material transporting frames 21. In this embodiment, the first direction is the left-right direction, and the second direction is the front-rear direction.

[0040] Specifically, the bumper group 200 is designed to be split left and right, and the two bumpers 201 are connected by a connecting rod 202. It should be noted that Figure 1 and Figure 2 one of the bumpers 201 is omitted in Figure 1 and Figure 2 The bumpers 201 shown are arranged symmetrically left and right. During the trimming process, the bumper group 200 in the previous process is transported to the material conveying mechanism 20. The two material conveying frames 21 of the material conveying mechanism 20 are arranged at intervals along the first direction, that is, the front-back direction. The two bumpers 201 are respectively carried on the two material conveying frames 21, and the two material conveying frames 21 can synchronously transport the bumper group 200 along the second direction, that is, the front-back direction. After the material conveying mechanism 20 transports the bumper group 200 to the trimming position, the manipulator grabs the two bumpers 201, and the pneumatic scissors 32 in the two support frames 31 of the trimming mechanism 30 cut the connecting rod 202 from the left and right sides respectively. The two bumpers 201 are separated, and the manipulator moves the separated two bumpers 201 away, completing the automatic trimming and transportation process of the bumper group 200, improving production efficiency, reducing labor costs, and reducing the labor intensity of workers.

[0041] Moreover, in the trimming device 100 of this embodiment, the two material conveying frames 21 can move towards or away from each other along the first direction, that is, the front-back direction, relative to the frame 10, so that the distance between the two material conveying frames 21 is adjustable, adapting to the distance between the two bumpers 201 in different models of bumper groups 200, with flexible use and good compatibility. At the same time, the two support frames 31 and the two material conveying frames 21 are linked in a one-to-one correspondence. While the two material conveying frames 21 move towards or away from each other relative to the support, the two support frames 31 can also move towards or away from each other to adaptively adjust the positions of the pneumatic scissors 32 on the two support frames 31, realizing flexible adjustment of the trimming amount of the connecting rod 202, maximizing the trimming amount, and being applicable to the trimming of the connecting rod 202 of various different models of bumper groups 200, with flexible and convenient use, good compatibility, large application range, and high degree of automation.

[0042] In one embodiment, the material conveying mechanism 20 further includes a distance adjustment drive assembly. The distance adjustment drive assembly includes a distance adjustment drive member 22, two synchronous wheels 23, and a synchronous belt 24 wound around the two synchronous wheels 23. The two synchronous wheels 23 divide the synchronous belt 24 into an upper transmission section 241 and a lower transmission section 242. The upper transmission section 241 and the lower transmission section 242 are respectively connected to the two material conveying frames 21. The distance adjustment drive member 22 is used to drive the upper transmission section 241 or the lower transmission section 242 to move along the first direction, so as to drive the two material conveying frames 21 to move towards or away from each other relative to the frame 10 along the first direction through the upper transmission section 241 and the lower transmission section 242; the material conveying frame 21 and the corresponding support frame 31 are connected by a first connecting plate 40.

[0043] The distance adjustment driving member 22 can adopt an electric cylinder in the prior art. The electric cylinder drives the upper transmission section 241 or the lower transmission section 242 to move left and right, so as to drive the upper transmission section 241 and the lower transmission section 242 to move in the same direction synchronously, and further drive the two material conveying frames 21 to move towards or away from each other in the left - right direction. The material conveying frame 21 and the corresponding support frame 31 are connected through a first connecting plate 40. That is, the left material conveying frame 21 and the left support frame 31 are connected through a first connecting plate 40, and the right material conveying frame 21 and the right support frame 31 are connected through another first connecting plate 40. When the two material conveying frames 21 move towards or away from each other in the left - right direction, the two support frames 31 are driven to move synchronously through the two first connecting plates 40. That is, the two support frames 31 are driven to move towards or away from each other left - right. While adjusting the distance between the two material conveying frames 21, the pneumatic scissors 32 are driven to adaptively adjust. The structural design is flexible and ingenious.

[0044] In one embodiment, the material conveying frame 21 includes a material conveying seat 211, a material conveying belt 212 and a material conveying driving assembly 213. The material conveying seat 211 is slidably installed on the frame 10. The material conveying belt 212 is installed on the material conveying seat 211, and the material conveying driving assembly 213 is used to drive the material conveying belt 212 to rotate relative to the material conveying seat 211, so as to convey the bumper group 200 along the second direction through the material conveying belt 212. The material conveying seat 211 and the corresponding support frame 31 are connected through a first connecting plate 40.

[0045] In one embodiment, the material conveying driving assembly 213 can adopt a mechanism of a motor cooperating with multiple driving rollers in the prior art. For example, the material conveying belt 212 is sleeved on multiple driving rollers, and the motor drives one of the driving rollers to rotate, and then drives the material conveying belt 212 to rotate relative to the support frame 31. After the bumper group 200 is carried on the material conveying belt 212, the material conveying belt 212 can convey the bumper group 200 along the second direction, that is, the front - rear direction, to the shearing position. The material conveying seat 211 and the corresponding support frame 31 are connected through a first connecting plate 40. When the material conveying frame 21 slides relative to the frame 10 in the left - right direction through its material conveying seat 211, the support frame 31 can be driven to slide relative to the frame 10 in the left - right direction.

[0046] In one embodiment, the frame 10 includes a first bracket 11, a second bracket 12, and a correction mechanism. The first bracket 11 and the second bracket 12 are arranged side by side in the second direction. The correction mechanism includes a first correction frame 13, a second correction frame 14, and a correction driving member 15. The first correction frame 13 is slidably mounted on the first bracket 11, the material transporting frame 21 is slidably mounted on the first correction frame 13, the second correction frame 14 is slidably mounted on the second bracket 12, and the support frame 31 is slidably mounted on the second correction frame 14. The first correction frame 13 and the second correction frame 14 are connected by a second connecting plate 50. The correction driving member 15 is configured to drive the first correction frame 13 to move relative to the first bracket 11 in the first direction, so as to drive the material transporting frame 21, the second correction frame 14, and the support frame 31 to move synchronously in the first direction.

[0047] As Figures 1 to 7 shown, the first bracket 11 and the second bracket 12 are arranged side by side in the front-rear direction. If there is a deviation in the mounting positions of the two bumpers 201 in the left-right direction after the bumper group 200 is transported to the trimming position, then, at this time, a correction mechanism is required to correct the deviation. Specifically, the correction driving member 15 drives the first correction frame 13 to move relative to the first bracket 11 in the first direction, that is, in the left-right direction. Since the material transporting frame 21 is mounted on the first correction frame 13, the support frame 31 is driven to move synchronously during the movement of the first correction frame 13. In addition, since the first correction frame 13 and the second correction frame 14 are connected by the second connecting plate 50 and the support frame 31 is mounted on the second correction frame 14, the second correction frame 14 and the support frame 31 are driven to move synchronously during the movement of the first correction frame 13. Furthermore, by the movement of the first correction frame 13, the material transporting frame 21, the second correction frame 14, and the support frame 31 are driven to move synchronously in the left-right direction to correct the deviation, ensuring the accuracy and consistency of the shearing position of the pneumatic scissors 32 on the connecting rod 202.

[0048] It can be understood that before the correction mechanism corrects the deviation, if it is necessary to adjust the distance between the two material transporting frames 21 according to the model of the bumper group 200, the material transporting frame 21 moves left and right relative to the first correction frame 13, and drives the second correction frame 14 to move left and right through the first connecting plate 40, so as to adjust the widths between the two material transporting frames 21 and between the two support frames 31 to adapt to the distance between the two bumpers 201 in different models of bumper groups 200. The material transporting frame 21 is specifically slidably mounted on the first correction frame 13 by a material transporting seat 211 to achieve the left-right sliding of the material transporting frame 21 relative to the first correction frame 13.

[0049] In one embodiment, the first bracket 11 is provided with a first slideway 111 arranged in the first direction. The first correction bracket 13 is provided with a first correction roller 131 that slidably cooperates with the first slideway 111. The first slideway 111 plays a guiding role, and the stable sliding of the first correction bracket 13 is achieved through the sliding cooperation between the first correction roller 131 and the first slideway 111. The first correction bracket 13 is provided with a first correction slideway 132 arranged in the first direction. The material transporting bracket 21 is provided with a material transporting roller 214 that slidably cooperates with the first correction slideway 132. The first correction slideway 132 plays a guiding role, and the stable sliding of the material transporting bracket 21 is achieved through the sliding cooperation between the material transporting roller 214 and the first correction slideway 132. The second bracket 12 is provided with a second slideway 121 arranged in the first direction. The second correction bracket 14 is provided with a second correction roller 141 that slidably cooperates with the second slideway 121. The second slideway 121 plays a guiding role, and the stable sliding of the second correction bracket 14 is achieved through the sliding cooperation between the second correction roller 141 and the second slideway 121. The second correction bracket 14 is provided with a second correction slideway 142 arranged in the first direction. The support bracket 31 is provided with a support roller 311 that slidably cooperates with the second correction slideway 142. The second correction slideway 142 plays a guiding role, and the stable sliding of the second correction bracket 14 is achieved through the sliding cooperation between the support roller 311 and the second correction slideway 142.

[0050] In one embodiment, in the bumper group 200, two bumpers 201 are connected by two connecting rods 202. The shearing device 100 for the connecting rods 202 of the bumper group 200 includes two shearing mechanisms 30. The two shearing mechanisms 30 are arranged oppositely along the second direction on both sides of the material transporting mechanism 20, and the pneumatic scissors 32 of the two shearing mechanisms 30 are respectively used to shear the two connecting rods 202. The height of one of the shearing mechanisms 30 is higher than that of the other shearing mechanism 30. In the shearing mechanism 30 with a higher height, each support bracket 31 is further connected with a sensing bracket 60, and a fiber optic sensor 64 for sensing the connecting rod 202 is arranged at the top of the sensing bracket 60.

[0051] As Figures 1 to 7As shown in the figure, two trimming mechanisms 30 are arranged oppositely on both sides of the material conveying mechanism 20 along the second direction, that is, along the front-back direction. The material conveying mechanism 20 conveys materials from front to back. The height of one trimming mechanism 30 located at the rear side is higher than that of one trimming mechanism 30 located at the front side. Moreover, the height of one trimming mechanism 30 located at the front side is lower than the height of the conveying belt 212 to avoid interference during the process of the conveying belt 212 conveying the bumper group 200. In one trimming mechanism 30 located at the rear side, each support frame 31 is further connected with an induction frame 60, and a fiber optic sensor 64 is arranged at the top of the induction frame 60. During the process of the material conveying mechanism 20 conveying the bumper group 200 from front to back, when the fiber optic sensor 64 senses the connecting rod 202 of the bumper group 200, the material conveying drive assembly 213 brakes, the conveying belt 212 stops running, and the bumper group 200 stays at the trimming position so that the connecting rod 202 can be trimmed by the pneumatic scissors 32 of the trimming mechanism 30 subsequently.

[0052] It can be understood that the material conveying frames 21 in each trimming mechanism 30 are detachably connected to the corresponding support frames 31 through the first connecting plates 40. Each trimming mechanism 30 is correspondingly provided with a second correction frame 14, and each second correction frame 14 is detachably connected to the first correction frame 13 through a second connecting plate 50, so as to realize the synchronous movement of the two trimming mechanisms 30 and the material conveying mechanism 20 towards or away from each other. Moreover, there is no interference between the trimming mechanism 30 and the material conveying mechanism 20. When maintaining or repairing the material conveying mechanism 20, only the material conveying mechanism 20 needs to be removed separately, which improves the convenience and efficiency of maintenance or repair.

[0053] In one embodiment, the induction frame 60 includes a connecting arm 61, a first support rod 62 and a second support rod 63. The connecting arm 61 is horizontally arranged, and the connecting end of the connecting arm 61 is connected to the corresponding support frame 31. The first support rod 62 is vertically arranged, and the bottom end of the first support rod 62 is connected to the free end of the connecting arm 61. The second support rod 63 is obliquely arranged, and the bottom end of the second connecting rod 202 is connected to the connecting arm 61. The top end of the second connecting rod 202 is connected to the top end of the first support rod 62 to form a triangular support structure with the connecting arm 61. The fiber optic sensor 64 is installed at the connection of the top ends of the first connecting rod 202 and the second connecting rod 202.

[0054] When the material conveying mechanism 20 transports the bumper group 200 to the shearing position from front to back, the connecting rod 202 of the bumper group 200 can first abut against the first support rod 62 in the induction frame 60. Since the first support rod 62, the second support rod 63 and the connecting arm 61 in the induction frame 60 form a triangular support structure with good structural stability, and the fiber optic sensor 64 is installed at the connection of the top of the first connecting rod 202 and the top of the second connecting rod 202, it can ensure that the fiber optic sensor 64 is not shaken when the connecting rod 202 abuts against the first support rod 62, and ensure the accuracy of the fiber optic sensor 64 in sensing the position of the connecting rod 202.

[0055] In an embodiment, the shearing device 100 for the connecting rod 202 of the bumper group 200 further includes a material receiving mechanism 70. The material receiving mechanism 70 is located between the two material conveying frames 21. The material receiving mechanism 70 includes a material receiving plate 71, a material pushing plate 72 and a material pushing driving member 73. The material receiving plate 71 is installed on the frame 10, and the material receiving plate 71 is provided with a material pushing gap 711 arranged in the second direction. The material pushing plate 72 extends out of the material pushing gap 711 and is located above the material receiving plate 71. The material pushing driving member 73 is located below the material receiving plate 71 and is used to drive the material pushing plate 72 to slide relative to the material receiving plate 71 along the material pushing gap 711.

[0056] The material pushing driving member 73 can adopt an electric cylinder in the prior art. The material receiving plate 71 is provided with a material pushing gap 711 arranged in the front-back direction. The material pushing driving member 73 can drive the material pushing plate 72 to slide along the material pushing gap 711, that is, the material pushing driving member 73 can drive the material pushing plate 72 to slide back and forth. After the pneumatic scissors 32 on the support frame 31 of the shearing mechanism 30 cut off the connecting rod 202 from the left and right sides, when the cut-off connecting rod 202 falls onto the material receiving plate 71, the material pushing driving member 73 drives the material pushing plate 72 to move from front to back, so that the material pushing plate 72 pushes the connecting rod 202 falling onto the material receiving plate 71 off the material receiving plate 71, so as to realize the recycling of the connecting rod 202 subsequently.

[0057] As Figures 1 to 8 shown, further, the shearing device 100 for the connecting rod 202 of the bumper group 200 further includes a recycling mechanism 80. The recycling mechanism 80 includes a recycling box 81. The recycling box 81 is located below the material receiving plate 71 and is distributed in a staggered manner with the material receiving plate 71. A guide plate 90 is also installed on the frame 10. The guide plate 90 is located between the material receiving plate 71 and the recycling box 81. The guide plate 90 includes a first guide section 91, a buffer section 93 and a second guide section 92 connected in sequence from top to bottom. The first guide section 91 and the second guide section 92 are inclined from the material receiving plate 71 towards the recycling box 81, and the buffer section 93 is horizontally arranged.

[0058] Specifically, the recycling bin 81 is located below the material receiving plate 71 and at the rear side of the material receiving plate 71. The first guiding section 91 of the guiding plate 90 is inclined downward and backward, the second guiding section 92 is inclined downward and backward, and the buffer section 93 is horizontally arranged. In this way, the connecting rod 202 pushed down from the material receiving plate 71 sequentially passes through the first guiding section 91, the buffer section 93, and the second guiding section 92 and is guided into the recycling bin 81. Both the first guiding section and the second guiding section 92 play a guiding role, and the buffer section 93 is horizontally arranged to play a buffering role, preventing the connecting rod 202 from directly falling into the recycling bin 81 under the action of inertia and avoiding making noise or causing damage due to a strong collision with the recycling bin 81.

[0059] In one embodiment, the recycling mechanism 80 further includes a recycling belt 82 and a recycling driving assembly 83. The recycling bin 81 is placed on the recycling belt 82, and the recycling driving assembly 83 is used to drive the recycling belt 82 to move in the first direction, so as to drive the recycling bin 81 to move to a position below the material receiving plate 71 or away from the material receiving plate 71 in the first direction.

[0060] In one embodiment, the recycling driving assembly 83 can adopt a pneumatic motor in the prior art or a structure of a driving motor and a synchronous belt 24-wheel. The recycling bin 81 is placed on the recycling belt 82. When the pneumatic motor drives the recycling belt 82 to move back and forth, the recycling bin 81 can move to the rear side below the material receiving plate 71. At this time, the pneumatic motor no longer drives the recycling belt 82, and the recycling belt 82 stops moving to facilitate the recycling of the cut-off connecting rod 202. When the recycling bin 81 is full of the connecting rod 202, the pneumatic motor drives the recycling belt 82 again, and the recycling bin 81 full of the connecting rod 202 moves to the recycling area along with the recycling belt 82. The operation of the recycling belt 82 in this embodiment can be controlled by the pneumatic motor. When it is not necessary to operate, only the pneumatic motor needs to pause driving, avoiding the waste of electricity caused by the long-term operation of the recycling belt 82 and saving energy consumption.

[0061] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
