Description

Technical Field

[0001] This invention relates to the field of parts assembly, specifically to a combination robot for furniture slide rail buffer brackets. Background Technology

[0002] Furniture drawer slides are metal sliding tracks. The slide rail bracket typically requires a damper, which is screwed into the damper and slide rail bracket by an industrial robot to secure them together. This allows the drawer to cushion the impact of sliding during use. However, in actual assembly, after the damper and slide rail bracket are assembled, workers must manually remove the assembled slide rail bracket from the assembly station and stack it on a tray. This process significantly increases the labor intensity for workers and has a low level of automation, failing to meet the production needs of the intelligent manufacturing equipment industry. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a combined robot for furniture slide rail buffer brackets.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a furniture slide rail buffer bracket combination robot, comprising an assembly table and a screw-driving industrial robot disposed behind the assembly table. Assembly components are disposed on the side of the assembly table, and a fixed frame is fixedly installed at the rear end of the assembly table. A guide frame is fixedly installed at one end of the fixed frame, and a slider is slidably installed inside the guide frame. A first protruding rib is slidably installed through one end of the slider, and a support plate is fixedly installed at the lower end of the first protruding rib. A pull-out wheel is connected to the other end of the slider. A third servo push cylinder is installed through the upper end of the fixed frame, and a lifting frame is fixedly installed at the output end of the third servo push cylinder. An upper inclined guide rail and a lower inclined guide rail are fixedly installed on the side of the lifting frame, with the upper inclined guide rail located above the lower inclined guide rail. The pull-out wheel is attached to the upper end of the lower inclined guide rail. A lowering component is disposed at the other end of the fixed frame, and a material tray is placed on the upper end of the assembly table.

[0005] Preferably, a pin hole is provided through the upper front edge of the material tray, and multiple positioning holes are provided in a linear array at the upper end of the assembly table. A pin is inserted through the pin hole and is inserted into one of the positioning holes. Multiple sets of corner brackets are arranged in a linear array at the upper end of the material tray. The spacing between the multiple sets of corner brackets is adapted to the spacing between the multiple positioning holes. Each set of corner brackets consists of four corner brackets, which are arranged in a square. The spacing between the four corner brackets is adapted to the size of the slide rail bracket.

[0006] Preferably, a second magnet is installed through the upper front corner of the pallet, a first magnet is installed through the front and rear ends of the slider, a support is fixedly installed at the lower end of the assembly table, and the screw-driving industrial robot is fixedly installed on the support.

[0007] Preferably, the lowering component includes a second protruding rib that is slidably mounted through and on the other end of the fixed frame. A lug is fixedly mounted on the lower end of the second protruding rib, and the lug is attached to the lower end of the support plate. The lower end of the lifting frame is slidably mounted on the outer surface of the second protruding rib. A spring is fixedly mounted between the lower end of the lifting frame and the upper end of the lug, and the second protruding rib passes through the inside of the spring.

[0008] Preferably, a positioning ring is coaxially fixedly installed on the outer surface of the second convex rod, and the lifting frame is attached to the lower end of the positioning ring.

[0009] Preferably, the assembly includes a support fixedly installed on the side of the assembly table, a first servo cylinder fixedly installed on one side of the support, a second servo cylinder installed at the output end of the first servo cylinder, and a limit holder fixedly installed at the output end of the second servo cylinder.

[0010] Preferably, the upper end of the support has two symmetrically extending positioning corner blocks, the distance between the two positioning corner blocks is adapted to the width of the buffer, the other side of the support is provided with a positioning frame, the distance between the front and rear end faces of the positioning frame is adapted to the width of the slide rail bracket, and the inner side of the positioning frame extends with a positioning plate, the positioning plate and the positioning frame are integrally formed.

[0011] Preferably, a connecting frame is fixedly installed on the side of the second servo push cylinder, and the end of the connecting frame is fixed to the output end of the first servo push cylinder. A support frame is fixedly installed on the side of the positioning frame, and the end of the support frame is fixed to the assembly table.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the assembly component presses the buffer into the slide rail bracket, and the screw-driving industrial robot screws into the buffer and slide rail bracket to assemble them, the No. 3 servo push cylinder will drive the lifting frame to move down, thereby driving the upper inclined guide rail to move down, so that the lower end face of the upper inclined guide rail can contact the pull plate wheel, and push the pull plate wheel backward, thereby driving the slider to slide backward in the guide frame, allowing the pallet to be pulled out from under the slide rail bracket, so that the assembled slide rail bracket can fall onto the material tray to complete the automatic unloading. After the assembly is completed, no manual unloading is required by the staff, which effectively reduces the labor intensity of workers, improves the degree of automation, and meets the production needs of the intelligent manufacturing equipment industry.

[0014] 2. When the No. 3 servo pusher cylinder moves the lifting frame downward, the lifting frame will push the lugs downward via springs. At this time, the No. 2 convex rod slides on the fixed frame to guide the lugs. The pallet, without the support of the lugs, will move downward under gravity. At this time, the No. 1 convex rod slides on the slider to guide the pallet, so that the assembled slide rail bracket can fall under the support of the pallet. After falling onto the material tray, the upper inclined guide rail continues to move downward to contact the pull plate wheel and push it backward, so that the pallet can be pulled away from under the slide rail bracket. This allows the assembled slide rail bracket to fall onto the material tray for stacking. During the falling process, the pallet supports the slide rail bracket as it falls, and after falling onto the material tray, the pallet is pulled away. This ensures that the assembled slide rail bracket falls horizontally and accurately into the corner bracket on the material tray for stacking, avoiding misalignment. Attached Figure Description

[0024] 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. 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.

[0025] This invention provides a technical solution: such as Figures 1-8The illustrated furniture slide rail damper bracket combination robot includes an assembly table 1 and a screw-driving industrial robot 2 located behind the assembly table 1. Assembly components are arranged on the side of the assembly table 1. Since the automatic screw-driving operation using the screw-driving industrial robot 2 is existing technology and widely used, it is not described in detail here. A fixing frame 10 is fixedly installed at the rear end of the assembly table 1, serving a supporting and fixing function. A guide frame 17 is fixedly installed at one end of the fixing frame 10, and a slider 20 is slidably installed inside the guide frame 17, allowing the slider 20 to slide. The slider 20 has a slidingly mounted protruding rod 18 at one end, and a support plate 21 is fixedly mounted at the lower end of the protruding rod 18. The protruding rod 18 guides the support plate 21, and the support plate 21 supports the slide rail bracket 8. The other end of the slider 20 is connected to a pull-out wheel 32. A third servo cylinder 15 is installed through the upper end of the fixed frame 10, and a lifting frame 16 is fixedly mounted at the output end of the third servo cylinder 15. The third servo cylinder 15 controls the movement of the lifting frame 16. An upper inclined guide rail 28 and an upper inclined guide rail 28 are fixedly mounted on the sides of the lifting frame 16. The lower inclined guide rail 25 and the upper inclined guide rail 28 are located above the lower inclined guide rail 25. The pull-out wheel 32 is attached to the upper end of the lower inclined guide rail 25. The upper inclined guide rail 28 pushes the pull-out wheel 32 backward to allow the tray 21 to be pulled out from under the slide rail bracket 8. The lower inclined guide rail 25 pushes the pull-out wheel 32 forward to allow the tray 21 to return to its original position. The other end of the fixing frame 10 is provided with a lowering component. The upper end of the assembly table 1 is provided with a material tray 3. When the assembly component presses the buffer 14 into the slide rail bracket 8, the screw-driving industrial robot 2 screws the screws 24 into the buffer 14 and the slide rail bracket 8 to secure the two components. After assembly, the No. 3 servo push cylinder 15 will drive the lifting frame 16 to move down, which in turn drives the upper inclined guide rail 28 to move down, so that the lower end face of the upper inclined guide rail 28 can contact the pull plate wheel 32 and push the pull plate wheel 32 backward, thereby driving the slider 20 to slide backward within the guide frame 17, allowing the tray 21 to be pulled away from under the slide rail bracket 8, so that the assembled slide rail bracket 8 can fall onto the material tray 3 to complete the automatic unloading. After the assembly is completed, no manual unloading is required by the staff, which effectively reduces the labor intensity of the workers, improves the degree of automation, and meets the production needs of the intelligent manufacturing equipment industry.

[0026] A pin hole 31 is provided through the upper front edge of the material tray 3. Multiple positioning holes 5 are provided linearly in the upper end of the assembly table 1. A pin 4 is inserted through the pin hole 31. By passing the pin 4 through the pin hole 31 and the positioning hole 5, the material tray 3 can be positioned so that a set of corner brackets 35 on the material tray 3 can be located below the tray 21 to wait for material to be unloaded. The pin 4 is inserted into the interior of one of the positioning holes 5. Multiple sets of corner brackets 35 are provided linearly in the upper end of the material tray 3. The corner brackets 35 can restrict the stacked slide rail supports 8 to prevent them from collapsing. The spacing between the multiple sets of corner brackets 35 is adapted to the spacing between the multiple positioning holes 5, which can ensure that when the material tray 3 is positioned by each positioning hole 5, each set of corner brackets 35 can be located below the tray 21. There are four corner brackets 35 in each set. The four corner brackets 35 are arranged in a square. The spacing between the four corner brackets 35 is adapted to the size of the slide rail support 8, which can ensure that the slide rail support 8 can smoothly enter the four corner brackets 35.

[0027] A second magnet 22 is installed through the upper front corner of the pallet 21. The second magnet 22 can attract the slide rail bracket 8, so that it will not shift when supported by the pallet 21. A first magnet 19 is installed through the front and rear ends of the slider 20. The first magnet 19 can attract the guide frame 17, so that the slider 20 will not slide by itself when there is no external force. A bearing seat 36 is fixedly installed at the lower end of the assembly table 1. The screw-driving industrial robot 2 is fixedly installed on the bearing seat 36. The bearing seat 36 serves to support the assembly table 1 and the screw-driving industrial robot 2.

[0028] The lowering component includes a second protruding rib 30 that is slidably mounted through the other end of the fixed frame 10. A lug 23 is fixedly mounted on the lower end of the second protruding rib 30, which guides the lug 23. The lug 23 fits against the lower end of the pallet 21. This fit design ensures that the pallet 21 is not obstructed during forward and backward sliding. Furthermore, when the slide rail bracket 8 is already stacked on the tray 3, the lug 23 moves downward, allowing the pallet 21 to support the slide rail bracket 8 with gravity as it moves downward. The tray 21 will press against the stacked slide rail brackets 8 below and cannot move further down, while the lug 23 will continue to move down until the second convex rod 30 slides down the fixed frame 10 to the end of its stroke. At this point, the lug 23 will remain stationary. Then, the inclined guide rail 28 will continue to move down, allowing the tray 21 to be pulled away from under the slide rail brackets 8 and fall onto the stacked slide rail brackets 8. The lower end of the lifting frame 16 is slidably mounted on the outer surface of the second convex rod 30, and a spring is fixedly installed between the lower end of the lifting frame 16 and the upper end of the lug 23. 26. The second protruding rod 30 passes through the inside of the spring 26. When the third servo push cylinder 15 moves the lifting frame 16 downward, the lifting frame 16 will push the lug 23 downward via the spring 26. At this time, the second protruding rod 30 slides on the fixed frame 10 to guide the lug 23. The support plate 21 will move downward under the action of gravity after losing the support of the lug 23. At this time, the first protruding rod 18 slides on the slider 20 to guide the support plate 21, so that the assembled slide rail bracket 8 can move downward under the support of the support plate 21. As the slide rails fall onto the tray 3, the inclined guide rail 28 continues to move downwards to contact the pull plate wheel 32 and push it backwards, allowing the pallet 21 to be pulled away from under the slide rail bracket 8. This allows the assembled slide rail bracket 8 to fall onto the tray 3 for stacking. During the falling process, the pallet 21 supports the slide rail bracket 8 as it falls, and after it falls onto the tray 3, the pallet 21 is pulled away. This ensures that the assembled slide rail bracket 8 falls horizontally and accurately into the corner bracket 35 on the tray 3 for stacking, avoiding misalignment.

[0029] A positioning ring 27 is coaxially fixedly installed on the outer surface of the second convex rod 30. The positioning ring 27 plays a positioning role, and the lifting frame 16 is attached to the lower end of the positioning ring 27.

[0030] The assembly includes a support 6 fixedly installed on the side of the assembly table 1. A first servo push cylinder 7 is fixedly installed on one side of the support 6. The support 6 serves to support the buffer 14. A second servo push cylinder 11 is installed at the output end of the first servo push cylinder 7. A limit holder 12 is fixedly installed at the output end of the second servo push cylinder 11.

[0031] The upper end of the support 6 has two symmetrically extending positioning corner blocks 13. The distance between the two positioning corner blocks 13 is adapted to the width of the buffer 14, which can ensure that the buffer 14 can be smoothly positioned between the two positioning corner blocks 13. The other side of the support 6 is provided with a positioning frame 9. The distance between the front and rear end faces inside the positioning frame 9 is adapted to the width of the slide rail bracket 8, which can ensure that the slide rail bracket 8 can be smoothly positioned inside the positioning frame 9. The inner side of the positioning frame 9 has a positioning plate 29, which is integrally formed with the positioning frame 9.

[0032] A connecting frame 33 is fixedly installed on the side of the second servo push cylinder 11. The end of the connecting frame 33 is fixed to the output end of the first servo push cylinder 7. The connecting frame 33 serves to fix the output ends of the second servo push cylinder 11 and the first servo push cylinder 7 together. A support frame 34 is fixedly installed on the side of the positioning frame 9. The support frame 34 serves to fix the positioning frame 9. The end of the support frame 34 is fixed to the assembly table 1.

[0033] During assembly, the buffer 14 is placed on the support 6 and fitted between the two positioning corner blocks 13. Then, the slide rail bracket 8 is fitted into the positioning frame 9 and rests against the positioning plate 29. At this time, the support plate 21 supports the slide rail bracket 8. Subsequently, the second servo cylinder 11 moves the limit holder 12 downwards to engage with the edge of the buffer 14. Then, the first servo cylinder 7 pushes the buffer 14 towards the slide rail bracket 8 to press and assemble the buffer 14 into the slide rail bracket 8. Afterwards, the second servo cylinder 11 and the first servo cylinder 7 reset. Then, the screw-driving industrial robot 2 begins its work, driving the screws... 24. Screw the buffer 14 and slide rail bracket 8 into place to assemble them. After assembly, the third servo pusher cylinder 15 drives the lifting frame 16 to move downward. The lifting frame 16 will push the lug 23 downward via the spring 26. At this time, the second convex rod 30 slides on the fixed frame 10 to guide the lug 23. The pallet 21 will move downward under gravity after losing the support of the lug 23. At this time, the first convex rod 18 slides on the slider 20 to guide the pallet 21, so that the assembled slide rail bracket 8 can fall onto the material tray 3 under the support of the pallet 21. Then the third servo pusher cylinder 15 continues... The lifting frame 16 moves downward. When the second convex rod 30 slides down the fixed frame 10 to the end of its stroke, the lug 23 remains stationary. At the same time, the lower end face of the upper inclined guide rail 28 contacts the pull plate wheel 32. Then, the lifting frame 16 drives the upper inclined guide rail 28 to continue moving downward. The lower inclined surface of the moving upper inclined guide rail 28 pushes the pull plate wheel 32 backward, thereby driving the slider 20 to slide backward within the guide frame 17, allowing the tray 21 to be pulled out from under the slide rail bracket 8. This allows the assembled slide rail bracket 8 to fall onto the material tray 3 to complete the automatic unloading. Then, the third servo push cylinder 15 drives the lifting frame 16 to move upward and reset. The tray 21 is pushed upward by the lug 23. When it is about to reach the end of its stroke, the upper surface of the inclined guide rail 25 just contacts the pull plate wheel 32. Then the lifting frame 16 drives the inclined guide rail 25 to continue to move upward, so that the upper inclined surface of the inclined guide rail 25 pushes the pull plate wheel 32 forward, thereby driving the tray 21 to move forward and reset. Then the next buffer 14 and slide rail bracket 8 can be assembled. After the assembly is completed, no manual unloading is required, which effectively reduces the labor intensity of workers, improves the degree of automation, and meets the production needs of the intelligent manufacturing equipment industry.
