Abstract
Description
Technical Field
[0001] This utility model relates to the field of six-axis robot technology, specifically to an adsorption-type manipulator. Background Technology
[0002] A six-axis robot is a multi-jointed industrial robot that achieves six degrees of freedom of spatial movement through six independent rotating axes driven by servo motors, simulating the flexibility of a human arm. It is commonly used in fields such as automated assembly, material handling, and welding.
[0003] During the use of existing technology, the inventors discovered that the heat dissipation capacity of the six-axis robot base motor is poor, and the motor is prone to high temperature, which accelerates the aging of the internal components and affects the service life of the motor. Utility Model Content
[0004] Based on the above description, this utility model provides an adsorption-type robotic arm to solve the problem of poor heat dissipation capacity of the existing six-axis robot base motor.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an adsorption-type manipulator includes a drive arm assembly and a base disposed at one end of the drive arm assembly. A liquid storage tank is installed on the inner side of the base. A heat sink extending outward is disposed through the inner side of the liquid storage tank. A circulation pipeline connects the inner and outer sides of the liquid storage tank. The circulation pipeline is spliced and fixed with the heat sink.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, an annular threaded groove is provided on the inner wall of the base near one end of the drive arm assembly, and a threaded ring is integrally formed on the open side of the liquid storage tank, the threaded ring being threadedly connected to the inner side of the annular threaded groove.
[0008] Furthermore, the surface of the liquid storage tank is attached to one end of the base near the drive arm assembly, and a sealing gasket is installed on one end of the threaded ring near the drive arm assembly, with the sealing gasket fitting the annular threaded groove near one end of the drive arm assembly.
[0009] Furthermore, the surface of the liquid storage tank is provided with through holes, and the surface of the liquid storage tank is integrally formed with a water inlet.
[0010] Furthermore, the heat sink is embedded in the inner wall of the liquid storage tank at the end away from the drive arm assembly, and extends through the liquid storage tank to the outside. The heat sink is arranged at equal intervals, and the side of the heat sink away from the drive arm assembly is provided with a rectangular array of slots, which are C-shaped.
[0011] Furthermore, the circulation pipeline includes a submersible pump and a heat dissipation pipe. The outlet end of the submersible pump is fixedly connected to the inside of the through hole and extends to the outside of the liquid storage tank. The inlet end of the submersible pump faces the inside of the liquid storage tank.
[0012] Furthermore, the diameter of the heat dissipation pipe is equal to the diameter of the groove, the heat dissipation pipe is installed inside the groove to form multiple bends, and the two ends of the heat dissipation pipe are respectively installed outside the water inlet and outside the water outlet of the submersible pump.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0014] This invention utilizes a liquid storage tank and heat sinks embedded inside the tank, along with heat dissipation pipes. The coolant in the tank directly contacts the surface of the six-axis robot's base motor, achieving a cooling effect. The heat sinks accelerate the outward diffusion of heat from the tank, while the heat dissipation pipes draw the coolant out, creating a circulating cooling system. The combination of the heat sinks and pipes further accelerates this circulating cooling process, significantly increasing the cooling rate of the coolant in the tank. This allows the coolant to effectively dissipate heat from the six-axis robot's base motor, reducing its operating temperature and extending its lifespan. Attached Figure Description

[0021] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0023] Please see Figure 1-4 The present invention provides an adsorption-type robotic arm, comprising a drive arm assembly 1 and a base 2 disposed at one end of the drive arm assembly 1. A liquid storage tank 3 is installed on the inner side of the base 2, and a heat sink 5 extending outward is disposed through the inner side of the liquid storage tank 3. A circulation pipeline connects the inner and outer sides of the liquid storage tank 3, and the circulation pipeline is spliced and fixed to the heat sink 5.
[0024] Please see Figure 1 The inner wall of the base 2 has an annular threaded groove 21 at one end near the drive arm assembly 1. The opening side of the liquid storage tank 3 has an integrally formed threaded ring 31, which is threadedly connected to the inner side of the annular threaded groove 21. The integrally formed threaded ring 31 reduces the processing cost, simplifies the installation and disassembly process of the liquid storage tank 3, and facilitates maintenance or replacement of coolant. The threaded connection and sealing design of the liquid storage tank 3 allows the coolant in the liquid storage tank 3 to directly contact the surface of the motor of the base 2 to achieve heat dissipation and enhance heat dissipation efficiency.
[0025] Please see Figure 1 The surface of the liquid storage tank 3 is attached to one end of the base 2 near the drive arm assembly 1. A sealing gasket 4 is installed on the threaded ring 31 near the drive arm assembly 1. The sealing gasket 4 fits the annular threaded groove 21 near the drive arm assembly 1. The sealing gasket 4 can fill the small gap at the threaded connection, prevent coolant from leaking from the threaded interface, improve the sealing performance, and the sealing gasket 4 can also absorb the vibration force generated by the drive arm assembly 1, reducing the impact of vibration on the sealing stability of the liquid storage tank 3. The surface of the liquid storage tank 3 is provided with a through hole 32, and the surface of the liquid storage tank 3 is integrally formed with a water inlet 33. The through hole 32 provides a fixed interface for the submersible pump 6, ensuring a reliable connection between the water pump and the liquid storage tank 3 and avoiding the interface from falling off due to water flow impact. The separate design of the through hole 32 and the water inlet 33 optimizes the liquid flow path and prevents the coolant inflow and outflow from interfering with each other.
[0026] Please see Figure 2The heat sink 5 is embedded in the inner wall of the liquid storage tank 3 at the end away from the drive arm assembly 1, and extends through the liquid storage tank 3 to the outside. The heat sink 5 is arranged at equal intervals. The side of the heat sink 5 away from the drive arm assembly 1 is provided with a rectangular array of slots 51. The slots 51 are C-shaped. The equally spaced heat sink 5 forms a bidirectional heat dissipation channel, which can evenly distribute the heat exchange area. The C-shaped slots 51 provide a snap-fit fixing position for the heat dissipation pipe 7, preventing the heat dissipation pipe 7 from displacement due to mechanical vibration or liquid flow impact, and enhancing the structural stability of the heat dissipation pipe 7. The rectangular array design of the slots 51 allows the heat dissipation pipe 7 to adjust the contact area and bending angle with the slots 51. The heat dissipation pipe 7 improves the heat dissipation efficiency of the internal coolant through the heat sink 5.
[0027] Please see Figure 2 The circulation pipeline includes a submersible pump 6 and a heat dissipation pipe 7. The outlet end of the submersible pump 6 is fixedly connected to the inside of the through hole 32 and extends to the outside of the liquid storage tank 3. The inlet end of the submersible pump 6 faces the inside of the liquid storage tank 3. The submersible pump 6 is built into the liquid storage tank 3, forming a self-priming circulation. No additional pressurization device is required, which simplifies the system structure. The submersible pump 6 is a miniature submersible pump 6 of model AW500S. The diameter of the heat dissipation pipe 7 is equal to the diameter of the retaining groove 51. The heat dissipation pipe 7 is installed inside the retaining groove 51 and forms multiple bends. The two ends of the heat dissipation pipe 7 are respectively installed outside the inlet 33 and outside the outlet end of the submersible pump 6. The heat dissipation pipe 7 connects the inlet 33 and the submersible pump 6, and together with the liquid storage tank 3, forms a circulation system. The multiple bends of the heat dissipation pipe 7 can extend the flow path of the coolant in the heat sink 5, increase the heat exchange time between the coolant and the heat sink 5, and improve the heat dissipation efficiency. The pipe diameter matches the retaining groove 51, and the assembly difficulty is reduced by snap-fit fixing.
[0028] When the cooling pipe 7 guides the coolant in the liquid storage tank 3 to the outside to form a circulating cooling system, the coolant in the cooling pipe 7 will pass through the heat sink 5, which will accelerate the cooling speed. The coolant in the liquid storage tank 3 can also be directly cooled through the heat sink 5. The heat sink 5 and the cooling pipe 7 work together to form a dual cooling mechanism, which can keep the coolant in the liquid storage tank 3 at a low temperature to cool the motor of the base 2, reduce the temperature of the motor when it is working, and extend the service life of the motor.
