A robotic arm for detachable booth assembly

Abstract

This invention discloses a detachable robotic arm for assembling exhibition booths, relating to the field of robotic arm technology. It includes a surrounding frame and a positioning plate. The positioning plate is fixedly installed on the bottom inner wall of the surrounding frame. A steel frame is installed inside the surrounding frame, and a robotic arm is fixedly installed on one side surface of the surrounding frame. This invention achieves this by using a climbing contact plate that, when in contact with the reinforcing steel frame, causes the entire device and robotic arm to climb along the surface of the steel frame due to torque. At this time, the contact rubber wheel rotates on the outer surface of the steel frame as the device moves, thus achieving overall climbing of the device. This overcomes the shortcomings of existing robotic arms, which are cumbersome to install and require disassembly of the fixing components between the robotic arm and the ground for secondary movement. This results in a small operating range for existing fixed-position robotic arms, and the installation and disassembly processes are cumbersome, leading to low efficiency in exhibition booth assembly.

Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, and in particular to a robotic arm for detachable booth assembly. Background Technology

[0002] A robotic arm is a complex system characterized by high precision, multiple inputs and multiple outputs, high nonlinearity, and strong coupling. Due to its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion protection, and other fields. As a complex system, a robotic arm is subject to uncertainties such as parameter perturbations, external interference, and unmodeled dynamics. Robotic arms are also widely used in the field of exhibition booth assembly technology, leveraging their high precision to facilitate faster and more efficient assembly of exhibition booths.

[0003] Existing robotic arms for booth assembly typically require manual installation by bolting the robotic arm to the ground. The robotic arm then grips various objects to facilitate manual installation. However, the installation of existing robotic arms is cumbersome, and if a secondary movement is needed, the fixings between the robotic arm and the ground must be disassembled before the movement can be achieved. This results in a limited operating range for existing fixed-position robotic arms, and the complicated installation and disassembly process leads to low booth assembly efficiency.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the issue that when the climbing contact plate contacts the reinforced steel frame, the torque causes the entire device and robotic arm to climb along the surface of the steel frame. At this time, the contact rubber wheel rotates on the outer surface of the steel frame as the device moves, achieving overall climbing of the device. This facilitates the robotic arm's displacement and climbing, enabling better high-altitude operations. This overcomes the shortcomings of existing robotic arm technologies, which involve cumbersome installation and require disassembly of the ground fixings for secondary movement. Furthermore, existing fixed-position robotic arms have limited operating ranges and are cumbersome to install and disassemble, resulting in low assembly efficiency for exhibition booths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detachable exhibition stand assembly robotic arm, comprising a surrounding frame and a positioning plate, wherein the positioning plate is fixedly installed at the bottom of the inner wall of the surrounding frame, a steel frame is installed inside the surrounding frame, a robotic arm is fixedly installed on one side surface of the surrounding frame, a first sprocket is rotatably installed on the inner wall of the positioning plate, a climbing chain is engaged on the outer surface of the first sprocket, a climbing contact plate is fixedly installed on one side surface of the climbing chain, anti-slip rubber is fixedly installed on the inner wall of the climbing contact plate, a second sprocket is engaged on the inner wall of the climbing chain, a driven rod is fixedly installed on the inner wall of the second sprocket, a first helical gear is fixedly installed on the outer surface of the driven rod, a disassembly assembly is installed on one side surface of the surrounding frame, and a climbing mechanism is installed on one side surface of the surrounding frame;

[0007] The disassembly assembly includes a docking plate, which is installed on one side surface of the enclosure frame. A docking groove is formed on one side surface of the enclosure frame, and a spiral hole is formed on one side surface of the docking plate. A reinforcing bolt is threaded onto the inner wall of the spiral hole.

[0008] Furthermore, the positioning plate has two equidistantly distributed on the bottom surface of the inner wall of the surrounding frame. Each positioning plate has a first sprocket distributed on its inner wall, and each first sprocket has a climbing chain distributed on its outer surface. The climbing contact plate has several of them arranged in a circular array on one side surface of the climbing chain, and each climbing contact plate has anti-slip rubber distributed on its inner wall.

[0009] Furthermore, the climbing contact plate and the anti-slip rubber are in movable contact with the steel frame, and the inner wall of each climbing chain is correspondingly engaged with a second sprocket. The inner wall of each second sprocket is correspondingly distributed with a driven rod and a first helical gear. The driven rod is movably rotatably connected to the inner wall of the surrounding frame.

[0010] Furthermore, the docking grooves are four arranged in a linear array on one side surface of the surrounding frame, and one side surface of the docking plate is in movable contact with one side surface of the surrounding frame. The spiral holes are four arranged in a linear array on one side surface of the docking plate, and a reinforcing bolt is rotatably installed on the inner wall of each spiral hole. The reinforcing bolt is rotatably connected to the inner wall of the docking groove through a thread.

[0011] Furthermore, the climbing mechanism includes a sliding component and a driving component. The sliding component includes a rotating groove, which is formed on one side of the inner wall of the surrounding frame and the docking plate. A damping bearing is fixedly installed on the outer side of the surrounding frame and the docking plate. A rotating rod is installed on the inner wall of the damping bearing, and a contact rubber wheel is fixedly installed on the outer surface of the rotating rod.

[0012] Furthermore, the rotating grooves are arranged in a circular array on the inner wall of the surrounding frame and the docking plate. Each rotating groove has a corresponding rotating rod on its inner wall, and each rotating rod has two corresponding contact rubber wheels on its outer surface. Each rotating rod also has two corresponding damping bearings on its outer surface. The contact rubber wheels make rolling contact with the outer surface of the steel frame.

[0013] Furthermore, the drive assembly includes a miniature reducer, which is fixedly mounted on one side surface of the surrounding frame. A drive shaft is mounted on the output end of the miniature reducer, and a second helical gear is fixedly mounted on the outer surface of the drive shaft. A drive motor is mounted on the output end of the miniature reducer.

[0014] Furthermore, the drive shaft extends from the outside of the surrounding frame to its interior, and the second helical gear has two equidistantly distributed on the outer surface of the drive shaft. The second helical gear meshes with the first helical gear, and the drive shaft is rotatably connected to the surrounding frame.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] This detachable robotic arm for assembling exhibition booths utilizes a climbing contact plate. When the climbing contact plate contacts the reinforced steel frame, the torque causes the entire device and robotic arm to climb along the surface of the steel frame. At this time, the contact rubber wheel rotates on the outer surface of the steel frame as the device moves, achieving overall climbing of the device. This facilitates the displacement and climbing of the robotic arm, enabling better high-altitude operations. This overcomes the shortcomings of existing robotic arms, which are cumbersome to install and require disassembly of the fixing parts between the robotic arm and the ground for secondary movement. This results in a limited operating range for existing fixed-position robotic arms, and the installation and disassembly process is cumbersome, leading to low efficiency in exhibition booth assembly.

[0026] 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.

[0027] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and 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. Therefore, they should not be construed as limitations on this invention.

[0028] like Figures 1-8As shown, the present invention discloses a detachable exhibition stand assembly robotic arm, including a surrounding frame 1 and a positioning plate 101. The positioning plate 101 is fixedly installed on the bottom of the inner wall of the surrounding frame 1. A steel frame 102 is installed inside the surrounding frame 1. A robotic arm 103 is fixedly installed on one side surface of the surrounding frame 1. A first sprocket 104 is rotatably installed on the inner wall of the positioning plate 101. A climbing chain 105 is engaged on the outer surface of the first sprocket 104. A climbing contact plate 106 is fixedly installed on one side surface of the climbing chain 105. Anti-slip rubber 107 is fixedly installed on the inner wall of the climbing contact plate 106. A second sprocket 108 is engaged on the inner wall of the climbing chain 105. A driven rod 109 is fixedly installed on the inner wall of the second sprocket 108. A first helical gear 110 is fixedly installed on the outer surface of the driven rod 109. A disassembly assembly is installed on one side surface of the surrounding frame 1. A climbing mechanism is installed on one side surface of the surrounding frame 1.

[0029] In this embodiment of the invention, when the climbing chain 105 rotates counterclockwise, the climbing contact plate 106 installed on its outer surface will move along the path of the climbing chain 105. As the climbing chain 105 continues to rotate, the climbing contact plate 106 will come into contact with the reinforced steel frame 102 installed inside the steel frame 102. Since the drive motor 403 is still in the starting state, when the climbing contact plate 106 comes into contact with the reinforced steel frame 102, the entire device and the robotic arm 103 will climb along the surface of the steel frame 102 due to the torque. At this time, the contact rubber wheel 303 will rotate on the outer surface of the steel frame 102 as the device moves as a whole, realizing the overall climbing of the device, thereby facilitating the displacement and climbing of the robotic arm 103, and enabling better high-altitude operations.

[0030] Reference Figures 1-8Specifically, the disassembly assembly includes a docking plate 2, which is installed on one side surface of the surrounding frame 1. A docking groove 201 is formed on one side surface of the surrounding frame 1, and a spiral hole 202 is formed on one side surface of the docking plate 2. A reinforcing bolt 203 is threaded onto the inner wall of the spiral hole 202. Four docking grooves 201 are arranged in a linear array on one side surface of the surrounding frame 1. One side surface of the docking plate 2 is in movable contact with one side surface of the surrounding frame 1. Four spiral holes 202 are arranged in a linear array on one side surface of the docking plate 2. A reinforcing bolt 203 is rotatably installed on the inner wall of each spiral hole 202. The reinforcing bolt 203 is rotatably connected to the inner wall of the docking groove 201 via a threaded connection. The positioning plate 101 has two equidistant... The inner wall of the surrounding frame 101 is covered with a first sprocket 104. The outer surface of each first sprocket 104 is covered with a climbing chain 105. The climbing contact plate 106 is arranged in a ring array on one side surface of the climbing chain 105. The inner wall of each climbing contact plate 106 is covered with anti-slip rubber 107. The climbing contact plate 106 and the anti-slip rubber 107 are in contact with the steel frame 102. The inner wall of each climbing chain 105 is engaged with a second sprocket 108. The inner wall of each second sprocket 108 is covered with a driven rod 109 and a first helical gear 110. The driven rod 109 is rotatably connected to the inner wall of the surrounding frame 1.

[0031] In this embodiment of the invention, the docking plate 2 is picked up and placed on one side surface of the surrounding frame 1, so that the docking plate 2 and the docking groove 201 provided on one side surface of the surrounding frame 1 are aligned with each other. When the alignment is completed, the docking plate 2 is pushed so that one side surface of the docking plate 2 is inserted into the inner wall of the docking groove 201, so that the docking plate 2 and the surrounding frame 1 are spliced ​​together. When the two are spliced ​​together, the reinforcing bolt 203 is inserted into the inner wall of the spiral hole 202 and rotated so that the reinforcing bolt 203 rotates in the inner wall of the spiral hole 202. By continuously rotating the reinforcing bolt 203, the reinforcing bolt 203 is finally inserted into the interior of the surrounding frame 1.

[0032] Reference Figures 1-8Specifically, the climbing mechanism includes a sliding component and a driving component. The sliding component includes a rotating groove 3, which is formed on one side of the inner wall of the surrounding frame 1 and the docking plate 2. A damping bearing 301 is fixedly installed on the outer side of the surrounding frame 1 and the docking plate 2. A rotating rod 302 is installed on the inner wall of the damping bearing 301. A contact rubber wheel 303 is fixedly installed on the outer surface of the rotating rod 302. Several rotating grooves 3 are arranged in a ring array on the inner wall of the surrounding frame 1 and the docking plate 2. Each rotating groove 3 has a corresponding rotating rod 302 on its inner wall. Each rotating rod 302 has two corresponding contact rubber wheels 303 on its outer surface. Each rotating rod 302 has two corresponding damping bearings 301 on its outer surface. The contact rubber wheels 303 roll in contact with the outer surface of the steel frame 102.

[0033] In this embodiment of the invention, the reinforcing bolt 203 is rotated again. The second rotation of the reinforcing bolt 203 causes the contact rubber wheel 303 to pre-press the surface of the steel frame 102, so that the contact rubber wheel 303 can fully contact the outer surface of the steel frame 102, preventing the robotic arm 103 from shaking due to loosening during lifting.

[0034] Reference Figures 1-8 Specifically, the drive assembly includes a small reducer 4, which is fixedly mounted on one side surface of the enclosure frame 1. A drive shaft 401 is mounted on the output end of the small reducer 4. A second helical gear 402 is fixedly mounted on the outer surface of the drive shaft 401. A drive motor 403 is mounted on the output end of the small reducer 4. The drive shaft 401 extends from the outside of the enclosure frame 1 to its interior. The second helical gear 402 has two equidistantly distributed gears on the outer surface of the drive shaft 401. The second helical gear 402 meshes with the first helical gear 110. The drive shaft 401 is rotatably connected to the enclosure frame 1.

[0035] In this embodiment of the invention, when the robotic arm 103 needs to climb to a certain height for operation after installation, the drive motor 403 is started. The output end of the drive motor 403 is connected to the output end of the small reducer 4. Therefore, when the drive motor 403 is started, the transmission shaft 401 installed at the output end of the small reducer 4 will rotate within the inner wall of the surrounding frame 1. A second helical gear 402 is installed on the outer surface of the transmission shaft 401. The second helical gear 402 rotates together with the transmission shaft 401, and the second helical gear 402 meshes with the first helical gear 110. Therefore, when the second helical gear 402 rotates, it will drive the driven rod 109 to rotate on the inner wall of the surrounding frame 1 through the first helical gear 110. The first sprocket 104 is fixedly installed on the outer surface of the driven rod 109. At this time, the first sprocket 104 will rotate with the driven rod 109. The climbing chain 105 meshes with the outer surface of the first sprocket 104 and the second sprocket 108. At this time, the climbing chain 105 will rotate counterclockwise. When the climbing chain 105 rotates counterclockwise, the climbing contact plate 106 installed on its outer surface will move along the path of the climbing chain 105.

[0036] Specific usage procedure: When the detachable booth assembly robotic arm 103 is needed, the steel frame 102 is first manually installed on the ground and fixed to the ground with bolts to build the external frame of the booth. When the external frame of the booth is built and the robotic arm 103 needs to be used for further installation, the surrounding frame 1 is lifted and aligned with the steel frame 102. The surrounding frame 1 is pushed to wrap around the steel frame 102. After wrapping, the connecting plate 2 is picked up and placed on one side of the surrounding frame 1, aligning the connecting plate 2 with the connecting groove 201 on one side of the surrounding frame 1. When aligned, the connecting plate 2 is pushed so that one side of the connecting plate 2 is inserted into the inner wall of the connecting groove 201, allowing the connecting plate 2 and the surrounding frame 1 to be spliced ​​together. When the two are spliced ​​together, Insert the reinforcing bolt 203 into the inner wall of the spiral hole 202 and rotate it so that the reinforcing bolt 203 rotates within the spiral hole 202. By continuously rotating the reinforcing bolt 203, it is eventually inserted into the interior of the surrounding frame 1, thereby fixing the connecting plate 2 and the surrounding frame 1 together. While the fixing bolt is rotating, observe the contact between the contact rubber wheel 303 and the outer surface of the steel frame 102. When all the contact rubber wheels 303 are in contact with the outer surface of the steel frame 102, rotate the reinforcing bolt 203 again. The second rotation of the reinforcing bolt 203 causes the contact rubber wheel 303 to pre-press the surface of the steel frame 102, so that the contact rubber wheel 303 can fully contact the outer surface of the steel frame 102, preventing the robotic arm 103 from shaking due to loosening during lifting.

[0037] When the robotic arm 103 needs to climb to a certain height for operation after installation, the drive motor 403 is started. The output end of the drive motor 403 is connected to the output end of the small reducer 4. Therefore, when the drive motor 403 starts, the transmission shaft 401 installed at the output end of the small reducer 4 will rotate on the inner wall of the surrounding frame 1. A second helical gear 402 is installed on the outer surface of the transmission shaft 401. The second helical gear 402 will rotate together with the transmission shaft 401, and the second helical gear 402 meshes with the first helical gear 110. Therefore, when the second helical gear 402 rotates, it will drive the driven rod 109 to rotate on the inner wall of the surrounding frame 1 through the first helical gear 110. A first sprocket 104 is fixedly installed on the outer surface of the driven rod 109. At this time, the first sprocket 104 will rotate with the driven rod 109. The outer surface of the second sprocket 108 is engaged with a climbing chain 105. The climbing chain 105 rotates counterclockwise. When the climbing chain 105 rotates counterclockwise, the climbing contact plate 106 installed on its outer surface will move along the path of the climbing chain 105. As the climbing chain 105 continues to rotate, the climbing contact plate 106 will come into contact with the reinforced steel frame 102 installed inside the steel frame 102. Since the drive motor 403 is still running, when the climbing contact plate 106 comes into contact with the reinforced steel frame 102, the torque will cause the entire equipment and the robotic arm 103 to climb along the surface of the steel frame 102. At this time, the contact rubber wheel 303 will rotate on the outer surface of the steel frame 102 as the equipment moves as a whole, realizing the overall climbing of the equipment, thereby facilitating the displacement and climbing of the robotic arm 103, and enabling better high-altitude operations.

[0038] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
