Description

Technical Field

[0001] This utility model belongs to the field of automotive manufacturing automation technology, specifically a robotic arm for automatically adjusting the electric switch of a car seat. Background Technology

[0002] Currently, in the automotive seat assembly process, the pressing, tossing, and rotating operations of electric switches largely rely on manual labor, resulting in low efficiency, high labor intensity, and susceptibility to errors. Existing robotic arms have the following shortcomings: a lack of dedicated execution modules for complex button shapes (such as embedded, lever, and knob types), an inability to achieve closed-loop control of visual positioning and motion execution, and a lack of deep integration solutions with collaborative robots. Functional limitations: traditional grippers cannot accommodate the combined operation of multiple types of switches (buttons / levers / knobs); insufficient precision: manual operation or simple machinery can easily lead to uneven force and positioning deviations, causing switch damage or malfunction triggering; lack of flexibility: fixed equipment cannot adapt to changes in the position / angle of seat switches in different car models, requiring readjustment during production changes; efficiency bottleneck: slow manual operation speed restricts production line cycle time. Utility Model Content

[0003] The technical solution of this utility model is as follows: a robotic arm for automatically adjusting the electric switch of a car seat includes: a six-axis collaborative robot mechanism and an intelligent finger mechanism, which are hinged together. The six-axis collaborative robot mechanism includes a collaborative robot and an intelligent finger mechanism. The intelligent finger mechanism includes a visual light source, a visual camera system, a finger system, and a robotic arm flange. The robotic arm flange is hinged to one end of a column. The column and the robotic arm flange are coaxial and can both rotate. The other end of the column is hinged to the finger system. The column is also hinged to the visual camera system. A visual light source is provided at the end of the visual camera system.

[0004] Furthermore, the finger system includes a single-finger elastic finger, a transverse two-finger twisting finger, a longitudinal two-finger twisting finger, and a contour-flicking finger.

[0005] Furthermore, it also includes a laser rangefinder sensor, which is located on one side of the vision camera system.

[0006] Furthermore, it also includes a safety lock, which is located on one side below the single-finger elastic finger.

[0007] The beneficial effects of this utility model are as follows:

[0008] This utility model's mechanism primarily simulates human hand operation of switches, integrating with a collaborative robot to automatically adjust the electric switches of car seats, completing some seat assembly and function testing tasks. Utilizing bionics, this utility model can completely replace manual labor at specific workstations in seat assembly. It achieves fully automatic, high-precision simulation of human hand movements, performing click, toggle, and turn operations on car seat switches. Its modular finger design is compatible with multiple switch types, adapting to the assembly and testing needs of different car models. Combining vision and laser positioning improves operational accuracy and flexibility, replacing manual workstations. This reduces assembly error rates and improves production consistency and efficiency. Attached Figure Description

Detailed Implementation

[0013] It should be noted that in the description of this utility model, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," and "joining" should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; a connection can be a mechanical connection or an electrical connection; a joint can be a direct connection or an indirect connection through an intermediate medium, and can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] A robotic arm for automatically adjusting the electric switch of a car seat includes: a six-axis collaborative robot mechanism 1 and an intelligent finger mechanism 2, which are hinged together.

[0016] The six-axis collaborative robot mechanism 1 includes a collaborative robot with a payload of 5KG.

[0017] The intelligent finger mechanism 2 includes a visual light source 21, a visual camera system 22, a single-finger elastic finger 23, a laser rangefinder sensor 24, a safety lock 25, a horizontal two-finger twisting finger 26, a robotic arm flange 27, a vertical two-finger twisting finger 28, and a contour-following finger 29.

[0018] The robotic arm flange 27 is hinged to one end of the column 210. The column 210 and the robotic arm flange 27 are coaxial and can both rotate.

[0019] The other end of the column 210 is hinged to the finger system, which includes a single-finger elastic finger 23, a transverse two-finger twisting finger 26, a longitudinal two-finger twisting finger 28, and a contour-flicking finger 29.

[0020] The column 210 is hinged to the vision camera system 22. A laser range sensor 24 is provided on one side of the vision camera system 22, and a vision light source 21 is provided at the end of the vision camera system 22.

[0021] The safety lock 25 is located on one side below the single-finger elastic finger 23.

[0022] The above components together form an intelligent finger mechanism, which, combined with vision and laser positioning, mainly realizes button clicking, flicking, twisting, and plugging / unplugging actions.

[0023] Connect the intelligent finger mechanism to a six-axis collaborative robot, such as the UR5 end flange.

[0024] Single-click action: A single flexible finger simulates a human hand pressing a button. The button shape and pressing position are determined by a vision camera, and the distance between the finger and the button is measured by a distance sensor. The trigger force is set to 0.5-1.5N to simulate the precise pressing of the button by a human hand.

[0025] Toggle action: Using a single finger with elasticity or contouring motion, the user toggles the elongated switch up and down or forward and backward. A vision camera determines the button's shape and position, a distance sensor measures the distance between the finger and the button, and the trigger force is set to 0.5-1.5N to simulate the precise toggle of a human hand.

[0026] Rotating action: Rotate the knob by rotating the two fingers horizontally or vertically. The contoured fingers have a built-in torque limiter (0.2-0.8Nm) to prevent overload damage to the knob.

[0027] Locking action: The safety lock is inserted into the seat belt lock, simulating the action of inserting and removing the seat belt.

[0028] Control system: PLC / industrial computer receives visual data → generates motion instructions → coordinates robot movement and finger operation.

[0029] Application scope:

[0030] Car seat assembly line (electric lumbar support / leg support / backrest adjustment button operation);

[0031] Seat function testing station (fully automated durability testing);

[0032] Debugging the complex switch assembly of multi-functional seats in new energy vehicles;

[0033] Personalized seat upgrades in the car modification market.
