Description

Technical Field

[0001] This application belongs to the field of lifting column technology, specifically relating to a lifting column. Background Technology

[0002] In modern industrial automation, intelligent manufacturing, and precision machining, robotic arms, as core actuators for automated operations, directly impact the efficiency and precision of the entire production system due to the flexibility of their installation and motion adjustment. To meet the needs of robotic arms operating at different heights, lifting columns, as important mounting, support, and height adjustment devices for robotic arms, are widely used in various automated production lines, assembly workstations, and testing equipment.

[0003] Lifting columns typically require a lifting mechanism that can move up and down along the column. A robotic arm is fixedly mounted on this mechanism, and the lifting motion adjusts the working height. However, in current mainstream lifting column designs, the lifting mechanism is often externally or semi-externally mounted, meaning the entire mechanism is located on the outside of the lifting column, or part of its structure is exposed outside the column body. This traditional design has gradually revealed several problems in practical applications:

[0004] First, since the lifting components are external or partially external, in order to ensure the stable movement of the lifting components and the installation space of the robotic arm, the lifting column often needs to be designed with a larger overall volume. This not only increases the area occupied by the equipment in workshops and other places, which is not conducive to the layout of compact production lines, but also increases the difficulty and cost of transporting and installing the equipment.

[0005] Secondly, external or semi-external lifting components are susceptible to various adverse interferences during robotic arm operation. On the one hand, vibrations and impacts generated by the robotic arm during high-speed movement or complex tasks are easily transmitted directly to the external lifting components, affecting the smoothness of their movement and positioning accuracy. On the other hand, dust, oil, coolant, metal shavings, and other impurities in the external environment easily adhere to the moving surfaces or transmission structures of the lifting components, leading to accelerated wear, shortening their service life, and increasing the frequency and cost of equipment maintenance. Furthermore, in operating environments with a risk of external collisions, external lifting components are also vulnerable to accidental impacts from external objects, causing structural damage or malfunctions.

[0006] Furthermore, robotic arms require connections to various control cables, power lines, and signal transmission lines during operation. These lines are typically connected to the lifting mechanism and move synchronously with it. With traditional external lifting mechanism designs, these connecting lines are exposed outside the support column, lacking effective protection. This not only makes the lines prone to entanglement, pulling, or friction with surrounding equipment during lifting, causing wear and breakage, affecting normal power supply, control signal transmission, or power delivery, and leading to production interruptions; but also affects the overall aesthetics of the equipment and increases the risk of accidents caused by operators accidentally touching the lines.

[0007] Furthermore, the main structure of traditional lifting columns often adopts an integrated welding or fixed connection method. When internal components such as the lifting mechanism and drive mechanism malfunction and require repair or replacement, the disassembly and installation process is cumbersome, resulting in low maintenance efficiency and further increasing equipment downtime and maintenance costs. At the same time, during the movement of external lifting components, their transmission structures, such as lead screws and guide rails, lack effective protection and are easily affected by the external environment, which reduces transmission accuracy and reliability, making it difficult to meet the needs of high-precision operation scenarios. Utility Model Content

[0008] This application provides a lifting column to solve the technical problems of traditional lifting columns, such as the lifting components being easily affected by external environmental interference, which affects their working stability and service life, as well as the difficulty in maintenance and repair of lifting columns.

[0009] The technical solution adopted in this application is as follows:

[0010] A lifting column includes: a main body, the main body being hollow to form a mounting cavity, the main body also including an opening communicating the mounting cavity with the outside; a lifting assembly, the lifting assembly being installed inside the mounting cavity and having a lifting member capable of moving up and down within the mounting cavity, the lifting member having a mounting surface facing the opening.

[0011] The lifting column described in this application also includes the following additional technical features:

[0012] The lifting assembly also includes a mounting plate and a drive mechanism mounted on the mounting plate. The mounting plate is located on the side of the mounting cavity opposite to the opening, and the drive mechanism drives the lifting component to move in the vertical direction.

[0013] Preferably, the mounting plate is provided with a guide on the side facing the opening, and the lifting member is provided with a mating member adapted to the guide. The lifting member moves vertically under the guidance of the guide and the mating member.

[0014] Preferably, the guide component is constructed as a guide rail extending in a vertical direction, and there are two guide rails distributed on both sides of the lifting component. The mating component is constructed as a sliding block with a guide groove, and the guide rail and the guide groove are slidably engaged.

[0015] Preferably, there are multiple sliding blocks arranged vertically at intervals on both sides of the lifting component, and the lifting component is detachably connected to the sliding blocks.

[0016] Preferably, the driving mechanism includes a drive motor located at the bottom of the mounting plate, the output end of the drive motor is connected to a transmission screw, the lifting member is equipped with a transmission nut sleeved on the transmission screw, and the drive motor drives the transmission screw to rotate so as to drive the lifting member to move up and down along the extension direction of the transmission screw.

[0017] Preferably, there are multiple transmission nuts arranged at vertical intervals, and the lifting component is detachably connected to the transmission nuts.

[0018] Preferably, the main body includes a bottom plate, side plates, a back plate, and a top plate. There are two side plates distributed on both sides of the opening. The back plate is located at the rear of the opening. The side plates and the back plate are detachably connected to the bottom plate and the top plate, respectively. The side plates are detachably connected to the back plate. The top plate, side plates, and bottom plate cooperate to form the opening.

[0019] Preferably, the lifting column further includes a drive motor and a control component. The drive motor is used to drive the lifting component to move up and down. The control component is electrically connected to the drive motor and controls the drive motor. The drive motor and the control component are respectively installed on the two side plates.

[0020] Preferably, the lifting column further includes a cable chain with a cable routing channel inside. The cable chain is located on the side of the lifting component and moves synchronously with the up and down movement of the lifting component.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0022] 1. The lifting column of this application includes a main body with an internal mounting cavity. By housing the lifting component within the mounting cavity, the lifting component is prevented from being exposed to the outside of the main body. The lifting component and the main body have a high degree of spatial overlap, which contributes to the miniaturization of the lifting column. In work scenarios with tight installation space requirements, this effectively reduces the equipment's footprint and adapts to compact production line layouts. Furthermore, the lifting component's location within the mounting cavity provides some protection for the lifting component. For example, in dusty machining workshops where metal shavings and coolant splashes are common, the main body of this application can effectively prevent some external impurities from intruding, reducing the maintenance and cleaning burden on the equipment and significantly decreasing the probability of the lifting component malfunctioning due to external environmental interference. Moreover, the robotic arm's pipelines can be introduced into the mounting cavity through openings and connected to the lifting component, reducing the volume of pipelines exposed to the outside of the main body. In scenarios with frequent worker traffic, this effectively reduces the probability of pipelines being accidentally bumped or pulled, ensuring the continuous and stable operation of the lifting column.

[0023] 2. The lifting assembly includes a mounting plate and a drive mechanism. The mounting plate is located on the side of the mounting cavity opposite to the opening, and the drive mechanism is mounted on the mounting plate. This structural design provides a stable mounting foundation for the drive mechanism. The connection between the mounting plate and the main body provides reliable support for the drive mechanism, reducing displacement deviations caused by vibration during the drive process and helping to improve the stability of the lifting motion. In scenarios requiring high-frequency lifting operations, such as precision assembly, stable drive support ensures the positioning accuracy of the robotic arm at different heights and reduces assembly errors caused by drive mechanism swaying. Simultaneously, the drive mechanism is located inside the mounting cavity, away from external interference at the opening. In scenarios with high cleanliness requirements, such as electronic component assembly workshops, the main body can provide additional protection for the drive mechanism, reducing the probability of dust and debris adhering to the drive components, reducing the risk of drive mechanism failure due to contamination, and extending the stable operating cycle of the equipment. Furthermore, the force direction of the drive mechanism and the lifting component is more aligned with the vertical movement trajectory. In heavy-duty robotic arm installation scenarios, this effectively distributes load pressure, helping to reduce the probability of structural deformation after long-term use and improving the overall structural reliability of the equipment.

[0024] 3. The guide and mating components work together to guide the lifting component vertically. This guiding and mating structure limits the lifting component's trajectory, reducing the probability of tilting, swaying, or deviating during movement, significantly improving the smoothness and accuracy of the lifting motion. In the installation of robotic arms in precision testing equipment, the robotic arm needs to perform high-precision testing operations at different heights. The precise guidance of the guide and mating components ensures that even minute displacements of the lifting component can be effectively controlled. In scenarios requiring high-speed lifting operations, such as product packaging production lines, traditional lifting structures are prone to jamming due to insufficient guidance. The guiding and mating structure of this design allows the lifting component to maintain smooth movement at high speeds, reducing noise and component wear caused by mechanical impact. Furthermore, the guide and mating structure can also share the radial load on the lifting component. When the robotic arm is lifting heavy objects, it effectively protects the drive mechanism, reducing the probability of damage to drive components due to overload and decreasing equipment maintenance frequency.

[0025] 4. The double-sided guide rails provide symmetrical force support for the lifting component. In operation scenarios with large lateral forces, such as large welding robotic arms, they can evenly distribute lateral loads, reducing the probability of rail deformation and movement jamming that are common in single-sided guide structures, ensuring that the lifting component maintains linear movement under load. The sliding fit between the sliding block and the guide rail has high sliding sealing performance. In environments with extremely high cleanliness requirements, such as semiconductor manufacturing workshops, it can reduce the entry of dust and impurities into the guide gap, reducing the decrease in motion accuracy caused by impurity accumulation. At the same time, the precise fit between the guide groove and the guide rail reduces the coefficient of friction during movement, reducing energy loss and improving equipment operating efficiency in automated production lines with long-term continuous operation. In addition, the double-sided guide rail design facilitates later maintenance. When a single-sided guide rail or sliding block is worn, it can be disassembled and repaired on one side without disassembling the entire lifting assembly, greatly improving maintenance convenience.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0047] like Figure 1 , Figure 2 As shown, a lifting column includes: a main body 1, the main body 1 being hollow to form an installation cavity 11, the main body 1 also including an opening 12 communicating the installation cavity 11 with the outside; a lifting assembly, the lifting assembly being installed inside the installation cavity 11 and having a lifting member 2 capable of moving up and down within the installation cavity 11, the lifting member 2 having a mounting surface 21 facing the opening 12.

[0048] The lifting column of this application includes a main body 1, with an installation cavity 11 inside. By housing the lifting component within the installation cavity 11, the lifting component is prevented from being exposed outside the main body 1. The lifting component and the main body 1 have a high degree of spatial overlap, which contributes to the miniaturization of the lifting column. In work scenarios with tight installation space requirements, this effectively reduces the equipment's footprint and adapts to compact production line layouts. Furthermore, the lifting component being located within the installation cavity 11 provides a certain degree of protection for the lifting component. For example, in dusty machining workshops where metal shavings and coolant splashes are common, the main body 1 of this application can effectively prevent some external impurities from intruding, reducing the maintenance and cleaning burden on the equipment, and significantly reducing the probability of the lifting component malfunctioning due to external environmental interference. Moreover, the robotic arm's pipeline can be introduced into the installation cavity 11 through the opening 12 and connected to the lifting component 2, reducing the volume of pipeline exposed outside the main body 1. In scenarios with frequent worker traffic, this effectively reduces the probability of pipelines being accidentally touched or pulled, ensuring the continuous and stable operation of the lifting column.

[0049] Specifically, the lifting component 2 has a plate-like structure and is provided with multiple through fixing holes, such as bolt holes, so that the robotic arm can be installed on the lifting component 2 by means of bolt connection, etc. When the robotic arm is installed on the lifting component 2, the robotic arm fits against the mounting surface 21.

[0050] As a preferred embodiment of this application, such as Figure 1 , Figure 2 As shown, the lifting assembly also includes a mounting plate 3 and a drive mechanism mounted on the mounting plate 3. The mounting plate 3 is located on the side of the mounting cavity 11 opposite to the opening 12. The drive mechanism drives the lifting component 2 to move in the vertical direction.

[0051] This structural design provides a stable mounting foundation for the drive mechanism. The connection between the mounting plate 3 and the main body 1 provides reliable support for the drive mechanism, reducing displacement deviations caused by vibration during the drive process and improving the stability of the lifting motion. In scenarios requiring high-frequency lifting operations, such as precision assembly, stable drive support ensures the positioning accuracy of the robotic arm at different heights, reducing assembly errors caused by drive mechanism swaying. Simultaneously, the drive mechanism is located inside the mounting cavity 11, away from external interference at the opening 12. In scenarios with high environmental cleanliness requirements, such as electronic component assembly workshops, the main body 1 provides additional protection for the drive mechanism, reducing the probability of dust and debris adhering to the drive components, decreasing the risk of drive mechanism failure due to contamination, and extending the stable operating cycle of the equipment. Furthermore, the force direction of the drive mechanism and the lifting component 2 better matches the vertical movement trajectory. In heavy-duty robotic arm installation scenarios, this effectively distributes load pressure, helping to reduce the probability of structural deformation after long-term use and improving the overall structural reliability of the equipment.

[0052] As a preferred embodiment of this implementation, such as Figure 1 , Figure 2 As shown, the mounting plate 3 is provided with a guide on the side facing the opening 12, and the lifting member 2 is provided with a mating part adapted to the guide. The lifting member 2 moves vertically under the guidance of the guide and the mating part.

[0053] The guide and mating components work together to guide the lifting component 2 vertically. This guiding and mating structure limits the movement trajectory of the lifting component 2, reducing the probability of tilting, swaying, or deviating during movement, significantly improving the smoothness and accuracy of the lifting motion. In the installation of robotic arms in precision testing equipment, the robotic arm needs to perform high-precision testing operations at different heights. The precise guidance of the guide and mating components ensures that even minute displacements of the lifting component 2 can be effectively controlled. In scenarios requiring high-speed lifting operations, such as product packaging production lines, traditional lifting structures are prone to jamming due to insufficient guidance. However, the guiding and mating structure of this design allows the lifting component 2 to maintain smooth movement at high speeds, reducing noise and component wear caused by mechanical impact. Furthermore, the guide and mating structure can also share the radial load on the lifting component 2. When the robotic arm is lifting heavy objects, it can effectively protect the drive mechanism, reducing the probability of damage to drive components due to overload and decreasing the frequency of equipment maintenance.

[0054] As a preferred example in this embodiment, such as Figure 1 , Figure 2 As shown, the guide component is constructed as a guide rail 5 extending in a vertical direction. There are two guide rails 5 distributed on both sides of the lifting component 2. The mating component is constructed as a sliding block 4 with a guide groove. The guide rail 5 slides in conjunction with the guide groove.

[0055] The double-sided guide rails 5 provide symmetrical force support for the lifting component 2. In operation scenarios with large lateral forces, such as large welding robotic arms, they can evenly distribute lateral loads, reducing the probability of rail deformation and motion jamming that are prone to occur in single-sided guide structures, ensuring that the lifting component 2 can still maintain linear movement under force. The sliding fit between the sliding block 4 and the guide rail 5 has high sliding sealing performance. In environments with extremely high cleanliness requirements, such as semiconductor manufacturing workshops, it can reduce the entry of dust and impurities into the gap between the guide groove and the guide rail 5, reducing the decrease in motion accuracy caused by impurity accumulation. At the same time, the precise fit between the guide groove and the guide rail 5 can reduce the coefficient of friction during movement, reducing energy loss and improving equipment operating efficiency in automated production lines that operate continuously for long periods. In addition, the structural design of the double-sided guide rails 5 facilitates later maintenance. When a single-sided guide rail 5 or sliding block 4 is worn, it can be disassembled and repaired on one side without disassembling the entire lifting assembly, greatly improving maintenance convenience.

[0056] Specifically, the guide groove is shaped with a tapered opening on the outside, the size of which is smaller than the internal size of the guide groove, so that the guide rail 5 cannot detach from the guide groove at the tapered opening. If it is necessary to separate the sliding block 4 from the guide groove or to assemble the two, the guide groove must be inserted into or removed from the end of the guide rail 5.

[0057] Preferably, such as Figure 2 As shown, there are multiple sliding blocks 4 arranged vertically at intervals on both sides of the lifting member 2, and the lifting member 2 and the sliding blocks 4 are detachably connected.

[0058] Multiple vertically spaced sliding blocks 4 enhance the support strength of the lifting component 2. During large-range lifting movements of the robotic arm, this reduces the probability of bending and deformation of the lifting component 2 due to insufficient support at a single point, making it particularly suitable for long-term use of heavy-duty robotic arms and improving the structural stability of the equipment. The detachable connection design between the sliding blocks 4 and the lifting component 2 makes the replacement of individual sliding blocks 4 more convenient. In scenarios such as automotive welding workshops where sliding blocks 4 experience high-frequency wear, traditional fixed structures require replacement of the entire guide component or mating parts. This structure, however, allows for independent replacement of individual components, enabling maintenance during short production line downtime and reducing equipment downtime. Furthermore, the detachable structure facilitates adjustment of the number and spacing of the sliding blocks 4 according to different load requirements. In flexible production lines, different materials or specifications of sliding blocks 4 can be used to adapt to different guiding needs under various working conditions, improving the equipment's versatility and applicability.

[0059] Specifically, the number of sliding blocks 4 can be set to four, distributed in pairs on the side of the lifting component 2. The sliding blocks 4 on one side are located at the top and bottom of the lifting component 2 respectively, and are bolted to the lifting component 2.

[0060] As another preferred embodiment of this implementation, such as Figure 1 , Figure 2 As shown, the driving mechanism includes a drive motor 6 located at the bottom of the mounting plate 3. The output end of the drive motor 6 is connected to a transmission screw 7. The lifting member 2 is equipped with a transmission nut sleeved on the transmission screw 7. The drive motor 6 drives the transmission screw 7 to rotate so as to drive the lifting member 2 to move up and down along the extension direction of the transmission screw 7.

[0061] The screw and nut helical drive system offers high transmission precision. In scenarios requiring precise positioning, such as precision electronic component assembly workshops, it enables micro-feed control of the lifting component 2, ensuring the operational accuracy of the robotic arm. Furthermore, the screw drive has excellent self-locking performance. In lifting columns of warehousing and logistics sorting systems, where the robotic arm needs frequent starts, stops, and reversals, this self-locking performance reduces the probability of the lifting component 2 accidentally sliding down due to gravity when stopped, improving equipment operational safety. In addition, the drive motor 6 is located at the bottom of the mounting plate 3, and the transmission screw 7 extends vertically, providing a direct and efficient power transmission path. In low-temperature or dusty industrial environments, compared to hydraulic drives, the screw drive is less affected by environmental conditions, reducing malfunctions caused by media leakage or contamination and lowering equipment maintenance costs.

[0062] Specifically, the bottom of the lead screw 7 has a transmission gear 10, and the output end of the drive motor 6 meshes with the transmission gear 10 and drives the lead screw 7 to rotate through meshing transmission.

[0063] Preferably, there are multiple transmission nuts arranged at vertical intervals, and the lifting component 2 is detachably connected to the transmission nuts.

[0064] Multiple vertically spaced transmission nuts can distribute axial loads. In scenarios such as heavy machine tool loading and unloading robotic arms that bear large axial loads for extended periods, this reduces the stress on individual transmission nuts, minimizes transmission accuracy degradation caused by localized wear of individual nuts, and extends the service life of the transmission nuts. The detachable connection design between the transmission nuts and lifting component 2 facilitates regular inspection and replacement of the transmission nuts, allowing for timely detection and replacement of nuts with hidden wear. This reduces the probability of production interruptions due to sudden transmission nut failures, ensuring production safety. Simultaneously, the synergistic effect of multiple transmission nuts can compensate for manufacturing errors in individual nuts, improving overall transmission accuracy. In operations requiring precise height control, this reduces positioning deviations caused by transmission backlash, further guaranteeing the operational quality of the robotic arm.

[0065] Specifically, the lifting component 2 is connected to the transmission nut bolt.

[0066] As a preferred embodiment of this application, such as Figure 1As shown, the main body 1 includes a bottom plate 13, side plates 14, a back plate, and a top plate 15. There are two side plates 14 distributed on both sides of the opening 12. The back plate is located on the rear side of the opening 12. The side plates 14 and the back plate are detachably connected to the bottom plate 13 and the top plate 15, respectively. The side plates 14 are detachably connected to the back plate. The top plate 15, the side plates 14, and the bottom plate 13 cooperate to form the opening 12.

[0067] This detachable structural design makes the assembly of the main body 1 more flexible. In the mass assembly scenario of automated production lines, the traditional integrated welded column main body 1 requires overall transportation and installation, increasing the difficulty of logistics and hoisting. However, the main body 1 in this embodiment can achieve decentralized transportation and on-site assembly of components, reducing transportation costs and installation barriers. When it is necessary to inspect the lifting components inside the mounting cavity 11, the detachable side plates 14 and back plates can be quickly disassembled, providing ample operating space for internal components. Compared with the traditional enclosed structure, this can significantly shorten inspection time and improve maintenance efficiency. In addition, the detachable connection makes it easy to change the material of the side plates 14 or back plates according to different operating environment requirements. For example, in corrosive environments, anti-corrosion plates can be replaced, and in high-temperature environments, high-temperature resistant components can be replaced, improving the equipment's adaptability to different working conditions and extending its overall service life.

[0068] As a preferred embodiment of this implementation, such as Figure 3 As shown, the lifting column also includes a drive motor 6 and a control component 8. The drive motor 6 is used to drive the lifting component 2 to move up and down. The control component 8 is electrically connected to the drive motor 6 and controls the drive of the drive motor 6. The drive motor 6 and the control component 8 are respectively installed on the two side plates 14.

[0069] The separate installation of the drive unit 6 and the control unit 8 facilitates independent sealing and protection of both components, reducing the probability of oil or dust spreading from the drive unit 6 to the control unit 8. This ensures the normal operation of the control unit 8 circuit and reduces the probability of equipment failure. Simultaneously, the layout distributed on both sides makes the equipment wiring more organized. Drive cables and control cables can be routed separately along the interior of the side panels 14, facilitating quick identification and troubleshooting of wiring faults during later maintenance. This is particularly suitable for the long-term use of complex control systems, reducing the difficulty of troubleshooting caused by messy wiring.

[0070] As a preferred embodiment of this application, such as Figure 4 As shown, the lifting column also includes a cable chain 9, which has a cable routing channel inside. The cable chain 9 is located on the side of the lifting component 2 and moves synchronously with the up and down movement of the lifting component 2.

[0071] The cable chain 9 assembly provides effective protection for the pipelines of the lifting component 2. In scenarios such as robotic arm production lines with vision inspection, the robotic arm needs to connect to various pipelines such as power supply, signal, and air supply. Traditional external pipelines are prone to entanglement with surrounding equipment during lifting movements. However, the internal cable routing channel of the cable chain 9 can neatly store all pipelines. When moving synchronously with the lifting component 2, the cable chain 9 can naturally bend and extend, reducing the probability of pipeline deformation or wear due to pulling and entanglement. In environments with dense pipelines, such as automobile assembly workshops, the cable chain 9 can prevent pipelines from directly rubbing against the lifting column or robotic arm components, reducing the risk of hydraulic oil leakage or signal interruption due to pipeline damage, and ensuring continuous and stable equipment operation. In addition, the cable chain 9 assembly is located on the side of the lifting component 2, without occupying the core space of the mounting cavity 11. The cable chain 9 itself has a certain degree of dustproof and waterproof performance, which can effectively protect pipelines in humid or dusty working environments, reduce their probability of external contamination, extend pipeline service life, and reduce equipment maintenance costs.

[0072] Furthermore, part of the drag chain 9 is located at the top of the lifting component 2, forming an inverted U-shape together with the part located on the side of the lifting component 2, making full use of the internal space of the main body 1.
