Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm lifting drive device and cabinet structure. Background Technology

[0002] In fields such as automated production and precision testing, cabinet-type equipment is widely used due to its superior protective performance. To automate operations such as material transfer, component gripping, and testing within the equipment, cabinet-type equipment is typically equipped with robotic arms. The drive mechanism that propels the robotic arm to move vertically and stably is a crucial component in ensuring the accuracy and efficiency of its operations.

[0003] During operation, the lifting drive device and cabinet structure of a robotic arm must withstand the weight of the robotic arm itself, the gripping load, and the inertial forces generated by the lifting motion. Therefore, high requirements are placed on the strength, rigidity, and stability of the load-bearing structure. However, to meet the needs of lightweighting and ease of forming, the cabinet walls of existing cabinet-type equipment are mostly made of thin-walled metal sheets through stamping or bending. Their structural strength and rigidity are limited, making them unsuitable as the direct load-bearing foundation for the drive device.

[0004] To address the issue of insufficient load-bearing capacity of the cabinet walls, the industry generally adopts a solution of adding metal beam structures inside the cabinet. These metal beams transfer the load of the drive unit to a more robust structure, such as the bottom of the cabinet or the equipment rack.

[0005] However, most existing metal beam structures only have a single load-bearing function. Their core design revolves only around "improving structural strength to bear the load" and has not been adapted or optimized for the installation requirements of robotic arm lifting drive devices and cabinet structures. Utility Model Content

[0006] In view of the problems pointed out in the background art, this utility model proposes a robotic arm lifting drive device and cabinet structure to solve the above-mentioned technical problems.

[0007] The technical solution of this utility model is implemented as follows: A robotic arm lifting drive device includes a vertically arranged slide rail with a drive block that can slide up and down connected to the slide rail. It also includes two vertically arranged beams spaced apart horizontally, each beam having a U-shaped cross-section and its openings facing away from each other. Furthermore, it includes two horizontal beams connected to the two vertical beams, spaced apart vertically. Front baffles are fixedly connected to the front sides of the two vertical beams, and rear baffles are fixedly connected to the rear sides of the two vertical beams. An installation space is formed between the front and rear baffles, and the slide rail is located within this installation space. The upper and lower ends of the slide rail are fixedly connected to the two horizontal beams, respectively. The front baffles have slots for the drive block to extend forward, and these slots extend vertically.

[0008] The present invention is further configured such that the drive block has two forward-extending mounting portions on the left and right, and a mounting plate is provided on the front side of the front baffle, with the left and right sides of the mounting plate respectively fixedly connected to the two mounting portions.

[0009] The present invention is further provided with triangular fixing seats on the front and rear sides of the lower end of the vertical beam.

[0010] The present invention is further configured such that both the front baffle and the rear baffle are detachable.

[0011] The present invention is further configured such that limit sensors are respectively provided at the upper and lower ends of the slide rail, and a sensing part corresponding to the limit sensor is fixedly provided on the drive block.

[0012] The present invention is further configured such that a motor is provided at the upper end of the slide rail, and the motor drives the drive block to move up and down through a lead screw.

[0013] The present invention is further provided that the two sides of the opening side of the vertical beam are respectively provided with inwardly bent fixing edges, and fixing holes are provided on the fixing edges.

[0014] A cabinet structure includes a base and the aforementioned robotic arm lifting drive device. The lower end of the vertical beam is fixedly connected to the base. It also includes a U-shaped front shell and a rear shell. The two sides of the front shell are fixedly connected to the front fixed edges of the two vertical beams, and the two sides of the rear shell are fixedly connected to the rear fixed edges of the two vertical beams.

[0015] The present invention is further configured such that the door body is transparent.

[0016] The present invention is further provided that the lower side of the base is provided with a support foot.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. The U-shaped vertical beam has a certain thickness in the front and rear directions. This, together with the front and rear baffles, can form an installation space.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] For reference as follows Figures 1-5 The present invention will be described as follows: Example: A robotic arm lifting drive device includes a vertically arranged slide rail 1, with a vertically sliding drive block 2 connected to the slide rail 1. A motor 14 is located at the upper end of the slide rail 1, and the motor 14 drives the drive block 2 to move up and down via a lead screw. Limit sensors 12 are respectively installed at the upper and lower ends of the slide rail 1. A sensing part 13 corresponding to the limit sensor 12 is fixedly installed on the drive block 2. The interaction between the sensing part 13 and the limit sensor 12 limits the extreme positions of the drive block 2's vertical movement. The limit sensor 12 is typically a photoelectric sensor or a proximity sensor. When the drive block 2 reaches its extreme position (such as the highest or lowest point), the sensing part 13 triggers the corresponding limit sensor 12. The sensor sends an electrical signal to the control system, which immediately stops the motor 14 to prevent the drive block 2 from continuing to move and colliding with the crossbeam 4, or the lead screw from exceeding its effective stroke and causing damage.

[0028] It also includes two vertical beams 3 that are set vertically and spaced apart on the left and right. The cross-section of the vertical beams 3 is U-shaped (compared to a flat plate structure of the same thickness, the U-shaped cross-section greatly improves the bending and torsional stiffness through cross-sectional shape optimization). The openings of the two U-shaped vertical beams 3 are set opposite to each other, so that the frame forms a symmetrical force structure in the left and right directions, ensuring that when the load is applied to the center position, the two vertical beams are subjected to balanced forces, further improving the overall load-bearing stability.

[0029] It also includes two horizontal beams 4 that are fixedly connected to the two vertical beams 3 respectively. The horizontal beams 4 are provided and are spaced apart vertically. The horizontal beams 4 are perpendicular to the vertical beams 3 and have a U-shaped cross section.

[0030] A front baffle 5 is fixedly connected to the front side of the two vertical beams 3, and a rear baffle 6 is fixedly connected to the rear side of the two vertical beams 3, forming an installation space 7 between the front baffle 5 and the rear baffle 6.

[0031] The slide rail 1 is located in the installation space 7, and the upper and lower ends of the slide rail 1 are fixedly connected to the two crossbeams 4 respectively.

[0032] The front baffle 5 is provided with a slot 8 for the drive block 2 to extend forward. The slot 8 extends in the vertical direction and provides a lifting and lowering space for the mounting part 9 of the drive block 2.

[0033] Installation space 7 enables independent installation and integration of the drive unit. Installation space 7 provides a dedicated installation area for core lifting drive components such as slide rail 1, drive block 2, motor 14, and lead screw. Each component can be centrally fixed inside the frame to avoid cross-interference with other components in the cabinet-type equipment.

[0034] The front baffle 5 and rear baffle 6 effectively prevent dust, oil, and other debris from entering the drive unit, avoiding contaminants adhering to the surfaces of moving parts such as lead screws and slide rails, which could lead to accelerated wear or decreased motion accuracy. Simultaneously, the baffle structure buffers external impacts, preventing the collision forces during robotic arm operation from directly acting on the core drive components, thus extending the device's lifespan.

[0035] The drive block 2 has two forward-extending mounting parts 9 on the left and right. The front side of the front baffle 5 is provided with a mounting plate 10, and the left and right sides of the mounting plate 10 are fixedly connected to the two mounting parts 9 respectively.

[0036] The drive block 2, mounting part 9, and mounting plate 10 will not come into contact with the front baffle 5 during the up and down movement. The mounting plate 10 serves as the mounting position for the robot arm.

[0037] Triangular mounting bases 11 are provided on both the front and rear sides of the lower end of the vertical beam 3. These are structures that secure the entire device to the cabinet-type equipment. The triangular structure provides extremely high stability.

[0038] Both the front baffle 5 and the rear baffle 6 are detachable. Both the front baffle 5 and the rear baffle 6 are fixedly connected to the vertical beam 3 by bolts. The detachable design of the front baffle 5 and the rear baffle 6 allows for quick removal of the baffles for operation when the drive unit needs maintenance or repair, without disassembling the entire load-bearing frame, thus reducing maintenance difficulty.

[0039] The vertical beam 3 has inwardly bent fixing edges 15 on both sides of its open side, and fixing holes are provided on the fixing edges 15. This structure provides an installation interface for the front housing 17 and the rear housing 18.

[0040] A cabinet structure includes a base 16, which serves as the basic load-bearing component of the cabinet structure. The base 16 is horizontally positioned and has supporting feet on its lower side. The base 16 serves to achieve a rigid connection between the lifting drive device and the cabinet. It also includes the aforementioned robotic arm lifting drive device, with the fixed base 11 at the lower end of the vertical beam 3 fixedly connected to the base 16 by bolts.

[0041] It also includes a U-shaped front housing 17 and a rear housing 18. The two sides of the front housing 17 are respectively fixedly connected to the front fixed edges 15 on the two vertical beams 3, and the two sides of the rear housing 18 are respectively fixedly connected to the rear fixed edges 15 on the two vertical beams 3.

[0042] The core function of base 16 is to achieve a rigid connection between the lifting drive device and the cabinet.

[0043] The unibody structure enhances rigidity and assembly efficiency. The front shell 17 and rear shell 18 are integrally formed through injection molding or metal stamping, avoiding the cumbersome process of splicing multiple panels in traditional cabinets. This not only improves the structural rigidity of the shell itself and reduces assembly gaps, but also reduces the number of parts, laying the foundation for rapid assembly and disassembly. The two sides and top edge of the U-shaped structure form a complete frame outline, which can effectively enclose the internal components of the cabinet and achieve a protective function.

[0044] The front housing 17 is fixed to the fixed edges 15 on the front of the two vertical beams 3 on both sides, and the rear housing 18 is fixed to the fixed edges 15 on the rear of the vertical beams 3 on both sides. This connection method directly utilizes the existing mounting interfaces (fixed edges 15 and fixing holes) of the lifting drive device, eliminating the need for additional mounting structures on the housing or vertical beams. Bolts can be passed through the fixing holes on the sides of the housing and the fixed edges 15 to complete the connection. The assembly process requires no special tools, significantly reducing installation time.

[0045] The opposing opening design achieves structural closure and spatial enclosure. The openings of the front shell 17 and the rear shell 18 are set facing each other. After installation, their sides are connected to form a complete side protection structure of the cabinet. Together with the subsequently installed cover 20, it can enclose a closed equipment storage space, effectively blocking the entry of external dust, moisture and debris, and providing protection for the internal lifting drive device and electrical components.

[0046] The front side of the front housing 17 has an opening window 19, to which a closable door is connected. The door is transparent and made of transparent materials such as acrylic or tempered glass, allowing operators to directly observe the operation of the robotic arm inside the cabinet without opening the door. The closable design of the door provides an operating channel for equipment maintenance, debugging, and material handling. When it is necessary to operate the internal components, the door can be quickly opened, and closed after the operation is completed to restore the protective state.

[0047] A cover 20 is connected to the upper ends of the front housing 17 and the rear housing 18, forming a top protective structure for the cabinet. The cover 20, together with the base 16, the front housing 17, and the rear housing 18, constitutes a complete six-sided protective system, further enhancing the protection of internal components, especially preventing foreign objects from falling from the top and damaging the equipment; secondly, it improves the overall rigidity of the cabinet structure. The connection of the cover 20 creates a top constraint between the front and rear housings, reducing vertical vibration and deformation of the housings and improving the stability of the entire cabinet structure.

[0048] The cabinet structure is supported by the vertical beam 3 of the lifting drive device. Through the modular design of "base + double shell + cover", it achieves multiple technical values: First, the structure is simple and compact, and it can be quickly connected by relying on the existing fixed edge 15 without complicated splicing process; Second, it is easy to disassemble and assemble, and each component is connected by bolts, which can be disassembled and replaced individually, reducing maintenance costs; Third, it provides comprehensive protection, and the combination of closed structure and transparent door takes into account both protection and monitoring needs; Fourth, it has strong integration and can work efficiently with the lifting drive device and internal auxiliary components to improve the overall integration level of the equipment.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
