Description

Technical Field

[0001] This invention relates to the field of industrial robots, and in particular to an industrial robot for nut insertion. Background Technology

[0002] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom robots designed for industrial applications. They are typical mechatronic equipment that performs automated tasks. Nut insertion industrial robots are industrial robot application units specifically developed for processes such as nut pressing, hot-melt insertion, and screwing insertion in industrial production. The core of the robot is to achieve automated insertion of nuts into workpieces such as plastic parts, sheet metal parts, and die-cast parts through precise positioning of the robot, a dedicated end effector, and matching tooling.

[0003] For workpieces with uneven surfaces that require nut implantation, existing technologies mostly involve embedding the workpiece into a corresponding mold to ensure stability and quality during the nut implantation process. However, whenever a different workpiece of a different specification is used for nut implantation, the robot needs to be stopped, consuming additional time to replace the corresponding mold before implanting the nut, which affects the operating efficiency of the industrial robot.

[0004] Therefore, it is necessary to propose an industrial robot for nut insertion to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide an industrial robot for nut insertion, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An industrial robot for nut insertion includes a base plate, a groove formed on the upper surface of the base plate, a mounting plate fixedly connected to the side wall of the base plate, an industrial robot arm that is mounted on the surface of the mounting plate, an adjustment plate rotatably connected to the end of the industrial robot arm away from the mounting plate, and a nut insertion mechanism fixedly connected to the lower surface of the adjustment plate. A mounting frame is provided above the base plate, and first rack columns are symmetrically fixedly connected to the outer side of the mounting frame. A plurality of first rack columns are meshed with first gears at the ends of their surfaces away from the mounting frame. A plurality of first gears are rotatably connected to the base plate, and second rack columns are symmetrically meshed with the outer side of the first gears. Two second rack columns are fixedly connected to U-shaped blocks at their ends away from the first gear. Movable sleeves are symmetrically fitted on the surfaces of the U-shaped blocks. Vertical columns are fixedly connected to the ends of the surfaces of the two movable sleeves away from the U-shaped blocks. The movable sleeves and vertical columns are slidably connected to the base plate. Multiple circular holes are opened on the surface of the vertical columns. T-shaped rods are slidably connected to the walls of the circular holes. First springs are sleeved on the outer side of the T-shaped rods. One end of the first springs is fixedly connected to the T-shaped rods, and the other ends of the multiple first springs are fixedly connected to the vertical columns.

[0007] Preferably, the inner side of the mounting frame is slidably connected to a first movable frame and a second movable frame, both of which are slidably connected to the adjustment plate.

[0008] Preferably, a first strip post and a second strip post are fixedly connected to the inner side of the mounting frame. There are two of each type of post. The two first strip posts are slidably connected to the first movable frame, and the two second strip posts are slidably connected to the second movable frame.

[0009] Preferably, the groove wall is symmetrically provided with through holes, and there are eight through holes. The vertical column and the movable sleeve are slidably connected to the through holes.

[0010] Preferably, the movable sleeve surface is symmetrically fixedly connected with limit strips, the through hole wall is symmetrically provided with limit grooves, and the limit strips are slidably connected with the limit grooves.

[0011] Preferably, a second spring is fixedly connected to the inner wall of each of the two movable sleeves at the end away from the U-shaped block, and the other end of each of the two second springs is fixedly connected to the U-shaped block.

[0012] Preferably, the second spring is initially in a compressed state.

[0013] Preferably, a positioning ring is fixedly connected to the surface of the base plate above the first gear, and the positioning ring is slidably connected to the first rack column.

[0014] Compared with the prior art, the present invention provides an industrial robot for nut insertion, which has the following beneficial effects: This industrial robot for nut insertion uses multiple T-shaped rods, second springs, and vertical columns to place the workpiece in a groove. The robotic arm adjusts the adjustment plate towards the groove. The first rack column meshes with the first gear, adjusting the movement of multiple second rack columns, which in turn simultaneously adjusts the movement of the movable sleeve and the vertical column. The ends of the T-shaped rods away from the second springs and the ends of the movable sleeves away from the U-shaped blocks are in contact with the workpiece surface. Utilizing the elastic force of the second springs, multiple T-shaped rods can make close contact with the sides of the workpiece, stably positioning it. Compared to existing technologies, this method eliminates the need for the industrial robot to be stopped and replaced with a different template when inserting nuts for different workpiece sizes, thus improving the robot's operational efficiency.

[0015] This industrial robot for nut insertion can simultaneously adjust multiple T-shaped columns and movable sleeves to stably position the workpiece as the robotic arm adjusts the nut insertion mechanism to move closer to the workpiece. It can adapt to the placement and positioning of workpieces of different specifications. Compared with the existing technology that uses template replacement to ensure stable workpiece placement, it simplifies the operation steps and is easy to use. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1 to 6 An industrial robot for nut insertion includes a base plate 1, a groove 11 formed on the upper surface of the base plate 1, a mounting plate 12 fixedly connected to the side wall of the base plate 1, an industrial robot arm 13 mounted on the surface of the mounting plate 12, an adjustment plate 14 rotatably connected to the end of the industrial robot arm 13 away from the mounting plate 12, and a nut insertion mechanism 15 fixedly connected to the lower surface of the adjustment plate 14. A mounting frame 2 is provided above the base plate 1. First rack columns 3 are symmetrically fixedly connected to the outer side of the mounting frame 2. First gears 4 are meshed with the ends of the surfaces of multiple first rack columns 3 away from the mounting frame 2. Multiple first gears 4 are rotatably connected to the base plate 1. Second rack columns 5 are symmetrically meshed with the outer side of the first gears 4. Two second rack columns 5 are fixedly connected to U-shaped blocks 6 at their ends away from the first gear 4. Movable sleeves 7 are symmetrically fitted on the surface of the U-shaped blocks 6. Vertical columns 8 are fixedly connected to the ends of the two movable sleeves 7 away from the U-shaped blocks 6. The movable sleeves 7 and vertical columns 8 are slidably connected to the base plate 1. Multiple round holes 9 are opened on the surface of the vertical column 8. T-shaped rods 10 are slidably connected to the walls of the round holes 9. First springs 101 are sleeved on the outside of the T-shaped rods 10. One end of the first springs 101 is fixedly connected to the T-shaped rods 10, and the other ends of the multiple first springs 101 are fixedly connected to the vertical columns 8. It should be noted that during the nut insertion process, the workpiece is simply placed on the groove wall of the groove 11, and the robotic arm adjusts the adjusting plate 14 towards the base plate 1. The nut insertion mechanism 15 and the mounting frame 2 move together with the adjusting plate 14. The first movable frame 21 and the second movable frame 22 are slidably connected to the adjusting plate 14, and both the first movable frame 21 and the second movable frame 22 can be adjusted and moved. During the adjustment and movement of the adjusting plate 14, the first movable frame 21 can move relative to the first strip post 23, and the second movable frame 22 can move relative to the second strip post 24. The first rack post 3 moves together with the mounting frame 2. The movement of the first rack post 3 can drive the first gear 4 to rotate, thereby driving the second rack post 5 to move. The movable sleeve 7 and the vertical column 8 can be adjusted and moved, and relative movement occurs between the movable sleeve 7 and the vertical column 8 and the through hole 111. Multiple T-shaped rods 10 first contact the workpiece surface. For workpieces with uneven surfaces, such as uneven plastic shells, due to the elastic force and extensibility of the first spring 101, the ends of multiple T-shaped rods 10 near the workpiece can contact the uneven surface of the workpiece, thereby completing the placement and positioning of the workpiece. When changing workpieces of different specifications for nut insertion, compared with the existing technology, there is no need to consume extra time to stop the industrial robot and change the corresponding template, which can improve the working efficiency of the industrial robot. After the workpiece is placed and positioned, the nut insertion mechanism 15 inserts the nut into the workpiece surface. Utilizing the elastic force of the second spring 71, the first rack column 3 can return to its initial position as the robotic arm adjusts the adjustment plate 14 moves away from the base plate 1, thus enabling the next nut insertion operation. It should be noted that during the process of the robotic arm adjusting nut implantation mechanism 15 moving towards the workpiece, multiple T-shaped columns and movable sleeves 7 can be adjusted simultaneously to stably position the workpiece. This can adapt to the placement and positioning of workpieces of different specifications. Compared with the existing technology of changing templates to ensure stable placement of workpieces, this simplifies the operation steps and makes it easier to use. It should be noted that the nut implantation mechanism 15 includes structures such as a telescopic cylinder, a guide cylinder, and a conveying channel, which are existing mature technologies and will not be described in detail here; a controller can be installed on the surface of the base plate 1 next to the mounting plate 12, and both the robotic arm and the nut implantation mechanism 15 are electrically connected to the controller, which is controlled by a computer.

[0020] The inner side of the mounting frame 2 is slidably connected to a first movable frame 21 and a second movable frame 22, both of which are slidably connected to the adjusting plate 14; the inner side of the mounting frame 2 is fixedly connected to a first strip post 23 and a second strip post 24, with two of each, the two first strip posts 23 being slidably connected to the first movable frame 21 and the two second strip posts 24 being slidably connected to the second movable frame 22; It should be noted that the first strip post 23 and the second strip post 24 can limit the movement and installation of the first movable frame 21 and the second movable frame 22, so as to avoid affecting the adjustment and movement of the nut insertion mechanism 15.

[0021] The groove 11 has eight through holes 111 symmetrically opened on its groove wall. The vertical column 8 and the movable sleeve 7 are slidably connected to the through holes 111. The movable sleeve 7 has a limit strip 71 symmetrically fixedly connected to its surface. The through hole 111 has a limit groove 1111 symmetrically opened on its wall. The limit strip 71 is slidably connected to the limit groove 1111. It should be noted that the through hole 111 and the limiting groove 1111 can limit the movement of the movable sleeve 7 and the vertical column 8, ensuring the stability of the movable sleeve 7 and the vertical column 8 during the adjustment and movement process.

[0022] A second spring 71 is fixedly connected to the inner wall of each of the two movable sleeves 7 at the end away from the U-shaped block 6, and the other end of each of the two second springs 71 is fixedly connected to the U-shaped block 6; the initial state of the second spring 71 is the compressed state. It should be noted that the reaction force generated by the compression of the second spring 71 acts on the surface of the U-shaped block 6. During the initial adjustment of the mounting frame 2 towards the base plate 1, the movement of the first rack column 3 drives the first gear 4 to rotate, which in turn drives the second rack column 5 to move. Due to the elastic force of the second spring 71, the second spring 71 will not deform temporarily before the end of the movable sleeve 7 away from the U-shaped block 6 and the surface of the vertical column 8 away from the U-shaped block 6 contact the workpiece surface. That is, the movable sleeve 7 can be smoothly adjusted and moved. After the multiple T-shaped rods 10 and After the workpiece surface contacts the vertical column 8 and the movable sleeve 7, that is, after the workpiece is placed and positioned, as the mounting frame 2 continues to be adjusted and moved closer to the base plate 1, the vertical column 8 and the movable sleeve 7 remain stationary, and relative movement occurs between the U-shaped block 6 and the movable sleeve 7. The second spring 71 is further compressed. Utilizing the elasticity of the second spring 71, it is possible to adapt to the placement and positioning of workpieces of different specifications, and then insert the nut. Compared with the existing technology of changing the template to ensure the stability of workpiece placement, it simplifies the operation steps and is easy to use.

[0023] A positioning ring 16 is fixedly connected to the surface of the base plate 1 above the first gear 4, and the positioning ring 16 is slidably connected to the first rack column 3; It should be noted that the positioning ring 16 ensures that the first rack column 3 remains stable during the adjustment and movement process, thus ensuring the stability of the entire industrial robot operation.
