Description

Technical Field

[0001] The present invention relates to the technical field of mechanical arms, and in particular to an industrial robot. Background Art

[0002] Industrial robots are a type of automated mechanical equipment widely used in the industrial field. They are usually composed of multiple joints or mechanical structures with multiple degrees of freedom. They can perform a variety of complex and precise industrial processing and manufacturing tasks. The design of industrial robots makes them highly automated. Relying on built-in power sources and advanced control systems, they can independently complete the work process, greatly improving production efficiency and quality.

[0003] The main reason for installing a dashboard on an industrial robot arm is to provide an operating interface so that the operator can monitor and control the robot's status and actions. The dashboard usually includes display screens, control buttons, indicator lights and other components, which can display the robot's working parameters, program status, fault information, etc., and allow operators to input instructions for programming and adjustment. This design improves the robot's operability and flexibility, and also facilitates maintenance and fault diagnosis.

[0004] In the prior art, since the dashboard is installed on a robotic arm, when the robotic arm rotates in a space and environment where it is not easy for workers to change the angle, the angle of the dashboard changes accordingly, making it difficult for workers to observe the dashboard and perform subsequent work at the first time, thereby affecting the overall work efficiency. Summary of the invention

[0005] The object of the present invention is to provide an industrial robot to solve the problem that the angle of the instrument panel changes with the robot arm.

[0006] The present invention is achieved through the following technical solutions:

[0007] An industrial robot comprises a workbench and further comprises:

[0008] A mechanical arm is rotatably mounted on a fixed arm on the top of the workbench, a rotation slot is provided on the mechanical arm, a dashboard is rotatably mounted on the rotation slot, and the dashboard is externally fixedly mounted on the top of the telescopic rod;

[0009] A roller is rotatably mounted at the bottom of the telescopic rod, the roller is rotatably mounted in a slide rail, and the slide rail is fixedly mounted on the top of the workbench to smoothly ensure that the dashboard can always be in a horizontal direction for observation by the staff.

[0010] Furthermore, a counterweight is fixedly mounted on the mechanical arm, and the counterweight and the instrument panel are symmetrically distributed about the mechanical arm, so as to maintain the gravity balance of the mechanical arm and improve stability.

[0011] Furthermore, a cleaning mechanism is provided on the slide rail, and the cleaning mechanism includes a cleaning hole, and the cleaning hole is fixedly opened on the slide rail. A collecting trough is opened on the top of the workbench, and the top of the collecting trough is arranged in contact with the edge of the slide rail to facilitate the collection of impurities.

[0012] Furthermore, a push plate is slidably installed on the workbench, an elastic element is provided between the outside of the push plate and the top of the workbench, a cleaning column is penetrated and slidably installed on the push plate, an elastic element is provided between the outside of the cleaning column and the outside of the push plate, and in the absence of external force, the elastic force of the elastic element is used to restore to the initial position.

[0013] Furthermore, a limit plate is slidably mounted on the outer wall at the bottom of the telescopic rod. The limit plate will slide in contact with the top of the slide rail due to its own gravity. An L-shaped fork plate is slidably mounted on the limit plate. An elastic element is provided between the outside of the L-shaped fork plate and the outside of the telescopic rod. In the absence of external force, the elastic force of the elastic element is used to restore the telescopic rod to its original position.

[0014] Furthermore, a semicircular protrusion is fixedly installed on the outside of the L-shaped fork plate, the bottom outer side of the upper half of the telescopic rod is set to be semicircular, and an arc-shaped extrusion plate is fixedly installed on the bottom of the L-shaped fork plate, and the bottom of the arc-shaped extrusion plate is set close to the outside of the push plate.

[0015] Furthermore, a clamping column is also provided on the slide rail, and the clamping column penetrates and is slidably installed on the top of the slide rail. The clamping column is integrally composed of a semicircular shape at the top and a right-angled triangle shape at the bottom.

[0016] Furthermore, the semicircular shape of the clamping column is arranged on the upper surface of the slide rail, the right angle side of the right triangle shape at the bottom of the clamping column is arranged in the direction of the push plate, and the hypotenuse of the right triangle shape at the bottom of the clamping column is arranged in the direction of the slide rail.

[0017] Furthermore, an elastic element is provided between the outside of the clamping column and the outside of the slide rail, and a clamping groove is provided on the top of the cleaning column.

[0018] Furthermore, one end of the card slot close to the slide rail is in a sealed state, and the other end of the card slot is in an open state. The sealed state facilitates squeezing the card column upward, and the open state facilitates the card column to leave the cleaning column.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] 1. The present invention arranges the instrument panel on the telescopic rod, and compensates for the vertical displacement of the instrument panel by the extension of the telescopic rod, and compensates for the horizontal displacement of the instrument panel by the displacement of the telescopic rod and the roller on the slide rail, thereby smoothly ensuring that the instrument panel can always be in a horizontal direction for staff to observe, effectively improving the convenience of using the instrument panel, facilitating staff to directly operate the mechanical arm, and is particularly suitable for use in a small range and in scenarios where it is difficult for staff to observe from multiple angles;

[0021] 2. In the present invention, when the semicircular protrusion and the L-shaped fork plate move toward the direction of the slide rail due to the pulling force of the elastic element, the movement of the L-shaped fork plate drives the arc-shaped extrusion plate to follow the movement, and the arc-shaped extrusion plate will separate from the push plate, and the push plate will move toward the direction of the slide rail due to the thrust of the elastic element, and the push plate will drive the cleaning column to follow the movement, and the cleaning column will pass through the cleaning hole to push and clean the impurities near the cleaning hole of the slide rail, and the cleaning column will push the impurities out of the slide rail, and the impurities will fall into the collection tank and be collected;

[0022] 3. In the present invention, when the limit plate moves to the top of the card column following the telescopic rod and continues to move, the limit plate will squeeze the card column downward through the semicircular shape on the top of the card column, so that the card column will move downward. In the process of the telescopic rod moving, the card column near the telescopic rod will be squeezed downward by the limit plate. The cleaning column is squeezed downward and stuck by the card column and cannot enter the cleaning hole, so that the cleaning column near the roller continues to enter the cleaning hole when the roller rolls and affects the moving path of the roller, thereby improving the safety during work and making the movement of the telescopic rod smoother.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0032] like Figures 1 to 6 As shown, the present invention provides an industrial robot, including a workbench 1, and also including:

[0033] A mechanical arm 2 is rotatably mounted on a fixed arm on the top of the workbench 1. A rotation slot 3 is provided on the mechanical arm 2. A dashboard 4 is rotatably mounted on the rotation slot 3. The dashboard 4 is externally fixedly mounted on the top of a telescopic rod 6. A counterweight 5 is fixedly mounted on the mechanical arm 2. The counterweight 5 and the dashboard 4 are symmetrically distributed with respect to the left and right of the mechanical arm 2.

[0034] A roller 7 is rotatably mounted at the bottom of the telescopic rod 6 , and the roller 7 is rollingly mounted in a slide rail 8 , and the slide rail 8 is fixedly mounted on the top of the workbench 1 .

[0035] In the above technical scheme, in order to keep the dashboard 4 always in a horizontal state for the convenience of observation by the staff, the dashboard 4 is rotatably installed on the mechanical arm 2. When the mechanical arm 2 rotates upward to lift the object, the mechanical arm 2 rotates upward, and the mechanical arm 2 drives the dashboard 4 to rotate upward, and the angle of the mechanical arm 2 changes. Since the dashboard 4 is fixed to the top of the telescopic rod 6, the dashboard 4 will rotate relative to the mechanical arm 2 during the angle conversion of the mechanical arm 2. The dashboard 4 itself will always be in a horizontal state, and the position of the rotation connection between the mechanical arm 2 and the dashboard 4 will be horizontally displaced. Therefore, the mechanical arm 2 will drive the dashboard 4 and the top of the telescopic rod 6 to move horizontally together, and the telescopic rod 6 will move horizontally. The rod 6 can extend itself while displacing horizontally to compensate for the vertical displacement of the robot arm 2 caused by the rotation. The horizontal displacement of the telescopic rod 6 will drive the roller 7 at the bottom to slide in the slide rail 8. Finally, by setting the dashboard 4 on the telescopic rod 6, the vertical displacement of the dashboard 4 is compensated by the extension of the telescopic rod 6, and the horizontal displacement of the dashboard 4 is compensated by the displacement of the telescopic rod 6 and the roller 7 on the slide rail 8, it is possible to smoothly ensure that the dashboard 4 can always be in a horizontal direction for observation by the staff, effectively improving the ease of use of the dashboard 4, and facilitating the staff to directly operate the robot arm 2. It is particularly suitable for use in small areas and scenarios where it is difficult for staff to observe from multiple angles.

[0036] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in the present invention, a cleaning mechanism is also provided, which includes a cleaning hole 9, which is fixedly opened on the slide rail 8. A collecting groove 10 is opened on the top of the workbench 1, and the top of the collecting groove 10 is arranged to fit the edge of the slide rail 8, so that impurities can directly fall into the collecting groove 10. A push plate 11 is slidably installed on the workbench 1, and an elastic element is provided between the outside of the push plate 11 and the top of the workbench 1. Here, a metal spring is used as the elastic element, so that the sliding of the push plate 11 has an elastic restoring force. In the absence of external force, the push plate 11 can be restored to its initial position due to the elastic force. A cleaning column 12 is penetrated and slidably installed on the push plate 11, and an elastic element is provided between the outside of the cleaning column 12 and the outside of the push plate 11. Here, a metal spring is used as the elastic element, so that the sliding of the cleaning column 12 has an elastic restoring force. In the absence of external force The limit plate 16 will slide on the top of the slide rail 8 due to its own gravity, and an L-shaped fork plate 13 is slidably installed on the limit plate 16. An elastic element is provided between the outside of the L-shaped fork plate 13 and the outside of the telescopic rod 6. The elastic element here uses a metal spring, which makes the sliding of the L-shaped fork plate 13 have elastic restoring force. In the absence of external force, the L-shaped fork plate 13 can return to its initial position. A semicircular protrusion 14 is fixedly installed on the outside of the L-shaped fork plate 13, and the bottom outer side of the upper half of the telescopic rod 6 is set to a semicircular shape, which is convenient for contact and extrusion with the semicircular protrusion 14. An arc-shaped extrusion plate 15 is fixedly installed on the bottom of the L-shaped fork plate 13, and the bottom of the arc-shaped extrusion plate 15 is set close to the outside of the push plate 11.

[0037] In the above technical solution, when the mechanical arm 2 rotates and drives the dashboard 4 to follow the movement, the dashboard 4 will drive the upper half of the telescopic rod 6 to follow the movement, and the entire telescopic rod 6 will be driven by the dashboard 4 to slide along the slide rail 8, and when the telescopic rod 6 is extended and retracted, the upper half will move up and down on the lower half to produce a telescopic effect, and when the upper half of the telescopic rod 6 moves to produce a telescopic effect, the initial semicircular shape will be directly located at the outermost end of the semicircular protrusion 14, and the elastic element on the L-shaped fork plate 13 is also in a stretched state at this time, and because the arc-shaped extrusion plate 15 at the bottom of the L-shaped fork plate 13 will squeeze the push plate 11, the initial state of the elastic element on the push plate 11 is in a compressed state, and when the upper half of the telescopic rod 6 will drive the outer semicircular shape to move upward, the semicircular protrusion 14 will gradually The semicircular protrusion 14 and the L-shaped fork plate 13 are gradually separated from the semicircular shape on the telescopic rod 6, so that the semicircular protrusion 14 and the L-shaped fork plate 13 will move in the direction of the slide rail 8 due to the pulling force of the elastic element. At this time, the movement of the L-shaped fork plate 13 drives the arc-shaped extrusion plate 15 to follow the movement, and the arc-shaped extrusion plate 15 will be separated from the push plate 11, and the push plate 11 will move in the direction of the slide rail 8 due to the thrust of the elastic element. The push plate 11 will drive the cleaning column 12 to follow the movement, and the cleaning column 12 will pass through the cleaning hole 9 to push and clean the impurities near the cleaning hole 9 of the slide rail 8. The cleaning column 12 will push the impurities out of the slide rail 8, and the impurities will fall into the collecting groove 10 and be collected together, so that during the rotation of the robot arm 2, the telescopic effect of the telescopic rod 6 can be used to effectively clean the impurities in the slide rail 8, and the impurities can be collected and processed in a centralized manner.

[0038] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in the present invention, a clamping column 17 is also provided, and the clamping column 17 passes through and is slidably installed on the top of the slide rail 8. The clamping column 17 is composed of a semicircular shape at the top and a right-angled triangle shape at the bottom. The semicircular shape of the clamping column 17 is arranged on the upper surface of the slide rail 8, which is convenient for contact and extrusion with the limit plate 16. The right-angled side of the right-angled triangle shape at the bottom of the clamping column 17 is arranged in the direction of the push plate 11, and the hypotenuse of the right-angled triangle shape at the bottom of the clamping column 17 is arranged in the direction of the slide rail 8. An elastic element is arranged between the outside of the clamping column 17 and the outside of the slide rail 8, so that the sliding of the clamping column 17 has an elastic restoring force. In the absence of external force, the clamping column 17 can be restored to the initial position due to the elastic force of the elastic element. A clamping groove 18 is opened on the top of the cleaning column 12, and the end of the clamping groove 18 close to the slide rail 8 is in a sealed state, and the other end of the clamping groove 18 is in an open state.

[0039] When the limit plate 16 moves along with the telescopic rod 6 to the top of the card post 17, the limit plate 16 will continue to move, and the limit plate 16 will squeeze the card post 17 downward through the semicircular shape at the top of the card post 17, so that the card post 17 will move downward. In the process of the movement of the telescopic rod 6, the card posts 17 near the telescopic rod 6 will be squeezed downward by the limit plate 16. After the card post 17 is squeezed downward, two situations will occur. The first is that the card post 17 is squeezed and moved downward into the card slot 18, and then the telescopic rod 6 continues to move, and the cleaning column 12 will move outward from the cleaning hole 9 of the slide rail 8, and the closed end of the card slot 18 will contact the bevel surface of the card post 17, and the cleaning column 12 will squeeze the card post due to the closed end of the card slot 18 When the clamping groove 18 is separated from the clamping column 17, the right-angled side of the clamping column 17 will face the cleaning column 12. At this time, if the cleaning column 12 moves toward the cleaning hole 9 due to the push of the push plate 11, the cleaning column 12 will be stuck by the right-angled side of the clamping column 17 and cannot continue to move, preventing the cleaning column 12 from continuing to enter the slide rail 8 and affecting the rolling of the roller 7. The second method is that the clamping column 17 is squeezed downward, and the right-angled side of the clamping column 17 directly faces the cleaning column 12, which can directly intercept the cleaning column 12. In this way, the cleaning column 12 cannot enter the cleaning hole 9 by being squeezed downward by the clamping column 17, preventing the cleaning column 12 near the roller 7 from continuing to enter the cleaning hole 9 and affecting the moving path of the roller 7 when the roller 7 rolls, thereby improving the safety during work and making the movement of the telescopic rod 6 smoother.

[0040] To summarize, by setting the dashboard on the telescopic rod, the vertical displacement of the dashboard is compensated by the extension of the telescopic rod, and the horizontal displacement of the dashboard is compensated by the displacement of the telescopic rod and the roller on the slide rail, the dashboard can be smoothly ensured to be always in a horizontal direction for observation by the staff, which effectively improves the convenience of using the dashboard and facilitates the staff to directly operate the robotic arm. It is particularly suitable for use in small areas and scenarios where it is difficult for staff to observe from multiple angles.

[0041] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
