Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, and in particular to a robot turntable base. Background Technology

[0002] In industrial robot operation scenarios, the performance of the turntable base directly affects the workpiece processing accuracy, equipment operation stability and maintenance costs. However, the design defects of existing robot turntable bases make it difficult to meet the needs of efficient and stable production. The design defects mainly include the following aspects: (1) The structure design of the platform is unreasonable and the functions cannot be taken into account. In order to realize the movement of the fixture, the existing platform has a single-direction or irregular groove. Such grooves can only play the role of guiding the fixture. Waste liquid (such as coolant and cleaning liquid) is easy to accumulate in the gap of the groove or the edge of the platform and cannot be quickly discharged. Although some platforms have added drainage channels, the channels and the movement path of the fixture interfere with each other, resulting in the limited installation position of the fixture and the inability to adapt to different specifications of workpieces. This not only reduces the versatility of the platform, but also increases the risk of workpiece corrosion and processing errors due to the accumulation of waste liquid. (2) There is no protective design inside the base, and the components are easily damaged. The load-bearing base and connecting base of the existing turntable base are mostly closed or semi-closed structures, and the problem of waste liquid and waste chips seeping in during the processing is not considered. When waste liquid leaks or waste debris falls from under the platform, it can easily enter the interior of the support base through the gap between the rotating shaft and the base, or the gap in the component installation. Long-term accumulation can cause the rotating shaft of the control device to jam, the motor to rust, reduce the rotation accuracy of the turntable, shorten the service life of the control device, and increase the equipment maintenance cost. (3) The drainage device is not reliable enough, and the problem of liquid accumulation is prominent. When the amount of waste liquid generated during the processing is large, or when the drain outlet is blocked by waste debris, the liquid cannot be discharged in time and will accumulate on the upper surface of the support base under the platform, and then seep into the base or overflow onto the worktable, polluting the equipment components and the production environment. At the same time, it increases the workload of manual cleaning and reduces production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a robot turntable base that can solve the problems of existing robot turntable bases, such as the inability of the platform to simultaneously allow for flexible movement of the gripper and efficient drainage of liquids, the easy accumulation of waste debris and waste liquid inside the base leading to damage to the control components, and the easy accumulation of liquid in the drainage device due to design defects.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a robot turntable base, including a base, a platform, a control device disposed within the base and controlling the rotation of the platform, a power connection device, and a drainage device. The platform is provided with a clamping groove in the shape of a square grid, and the cross-sectional shape of each groove of the clamping groove is an inverted "T" shape. The end of each groove of the clamping groove extends to the periphery of the platform. The bottom of the base is provided with a drainage hole for draining waste liquid entering the base. The drainage device includes a water collection plate installed on the base and a drain outlet installed on the water collection plate. The water collection plate is installed around the platform and is used to receive waste liquid from the platform. The top-view projection range of the platform during rotation falls entirely within the range of the water collection plate.

[0005] By adopting the above technical solution, the fixture slots on the platform provide a moving channel for fixture installation (moving along the fixture slots during installation) while also allowing waste liquid to flow out from the end of each slot, improving the flow and drainage capacity of waste liquid on the platform surface. This balances workpiece clamping flexibility with waste liquid treatment efficiency. The base also features dual drainage protection, both internally and externally. An external drainage device quickly drains liquid from under the platform, while drainage holes promptly remove waste debris and liquid entering the base, protecting internal control devices and extending the overall service life of the turntable base. Ultimately, this solution addresses the problems of existing robot turntable bases, such as the inability of the platform to simultaneously accommodate flexible fixture movement and efficient liquid drainage, the susceptibility of control components to damage due to waste debris and liquid accumulation inside the base, and the tendency for liquid accumulation in drainage devices due to design flaws.

[0006] A further feature of this invention is that the drain hole is located at the bottom center of the base.

[0007] By adopting the above solution, and placing the drain hole at the center bottom of the base, the path of waste liquid discharge is shortened, thereby improving drainage efficiency.

[0008] A further feature of this invention is that the number of drain outlets is not less than two, the water collection plate is polygonal, and the drain outlets are located at the corners of the water collection plate.

[0009] By adopting the above technical solution and setting multiple drainage outlets, the reliability of the drainage structure is improved, the problem of liquid accumulation caused by blockage of a single drainage outlet is avoided, the liquid is discharged efficiently and stably, the processing environment is kept clean, and the production auxiliary costs are reduced.

[0010] A further feature of this invention is that the drain outlet extends downward at an angle away from the water collection plate.

[0011] By adopting the above technical solution, the drain outlet extends downwards at an angle away from the water collection plate, thereby improving drainage efficiency.

[0012] The present invention is further configured as follows: the base includes a supporting base and a connecting base disposed on the side of the supporting base; the platform is located above the supporting base; the water collection plate is disposed on the upper surface of the supporting base and located below the platform; the control device includes a rotating shaft rotatably connected in the supporting base, a motor disposed in the supporting base and the connecting base and linked with the rotating shaft, the upper end of the rotating shaft protruding from the connecting base and connected to the center bottom of the platform; the power connection device is disposed in the connecting base, and the power connection device is electrically connected to the motor of the control device.

[0013] By adopting the above technical solution, the support base can be used to install the rotating shaft and water collection plate, and the connecting base can cover the power connection device; the control device includes a rotating shaft and a motor to control the rotation of the platform.

[0014] A further feature of this invention is that: one end of the connecting base protrudes from the top view projection range of the water collection plate, and a power connection port is provided on the side of the end of the connecting base protruding from the top view projection range of the water collection plate; the power connection device is connected to an external power supply device through the power connection port; and a waterproof cover covering the power connection port is provided on the side of the connecting base.

[0015] By adopting the above technical solutions, existing power connection devices lack effective protection and are susceptible to environmental interference. The power connection port of the turntable base is a critical component for ensuring equipment power supply. Existing products often lack dedicated protective structures or only use simple plastic covers. In machining environments, metal shavings and coolant splashes can easily enter the power connection port, causing oxidation of metal contacts and short circuits. This not only requires frequent disassembly and cleaning of the power connection device but can also lead to processing interruptions due to sudden power outages, affecting production progress and even causing equipment failure. In this case, the installation of a waterproof cover can enhance the protective performance of the power connection structure, preventing damage to the power connection port from liquids and debris in the machining environment, ensuring the stability of the turntable base's power supply, and reducing maintenance frequency.

[0029] Implementation effects: (1) By setting the fixture slot 21 on the platform 2, while providing a moving channel for fixture installation (moving along the fixture slot 21 during fixture installation), waste liquid can also flow out from the end of each slot of the fixture slot 21, improving the flow and discharge capacity of waste liquid on the surface of the platform 2, thus taking into account both workpiece clamping flexibility and waste liquid treatment efficiency; (2) Achieving double drainage protection inside and outside the base 1, both quickly draining the liquid under the platform 2 through the external drainage device 5, and timely draining the waste debris and waste liquid entering the base 1 through the drainage hole 13, protecting the internal control device 3, and extending the overall service life of the turntable base; (3) By setting multiple drainage ports 52, the reliability of the drainage structure is improved, avoiding the problem of liquid accumulation caused by the blockage of a single drainage port 52, ensuring efficient and stable liquid discharge, maintaining a clean processing environment, and reducing production auxiliary costs; (4) By setting the waterproof cover 15, the protective performance of the electrical connection structure can be enhanced, avoiding damage to the electrical connection port 14 caused by liquid and debris in the processing environment, ensuring the power supply stability of the turntable base, and reducing the frequency of maintenance.
