Description

Technical Field

[0001] This utility model relates to the field of power-assisted robotic arms, and in particular to a front panel power-assisted robotic arm. Background Technology

[0002] In automobile manufacturing, front bulkhead assisted robotic arms are widely used in final assembly and welding lines. They can precisely handle and install front bulkheads, ensuring the efficiency and safety of the assembly process. With continuous technological advancements, these assisted robotic arms will become more intelligent and autonomous, achieving more efficient production processes through collaboration with other equipment in the factory. Through automated and precise operation, assisted robotic arms can significantly improve production efficiency. Compared to manual operation, robotic arms operate faster and more accurately, completing a large number of tasks in a short time. For repetitive and high-intensity work, assisted robotic arms can replace manual labor, reducing the physical burden on workers, helping to protect their health and improve job satisfaction. Due to their high operational precision and stability, assisted robotic arms can greatly improve product quality and consistency, making them particularly important in precision manufacturing.

[0003] Currently, most truck front panels are installed by hand, with the panels being moved to the front of the vehicle. Some automakers also use simple lifting tools or overhead cranes for hoisting. These installation methods may limit flexibility, with some joints having a small range of motion, making it difficult to perform complex and delicate movements, especially when performing multi-angle operations in confined spaces.

[0004] Some front panel lifting devices have limitations in load capacity, making it difficult to easily and conveniently grab and move objects. If the lifting machine has only one load function, its operation becomes inflexible and unfree when installing and aligning holes, which may lead to shaking or even structural damage, affecting the stability and accuracy of the work.

[0005] The structure of a front panel-assisted robotic arm can be quite complex, with numerous components. This not only increases manufacturing and maintenance costs but also raises the probability of malfunctions. If even one component fails, the entire robotic arm may malfunction.

The column 3 is installed at the middle position of the top of the cross frame 1. A connecting flange 31 is provided at the top of the column 3. A pitch balancing component 32 is provided on the connecting flange 31. A pitch balancing cylinder 33 is provided at the front end of the column 3. Brackets 4 are installed on both sides of the bottom of the cross frame 1. Guide components 41 are installed on the brackets 4, and guide rests 42 are fixed on the guide components 41.

[0027] There are two manual pins 11, which are symmetrical on both sides of the center line at the rear end of the cross frame 1.

[0028] There are two auxiliary handles 14, which are symmetrical on both sides of the center line of the cross frame 1.

[0029] There are two brackets 4, which are symmetrical on both sides of the bottom center line of the cross frame 1.

[0030] The support assembly includes support rod 1 5 installed on both sides of the base frame 2. The top of support rod 1 5 is provided with movable block 1 51, the bottom of movable block 1 51 is provided with pressure block 1 52, the top of movable block 1 51 is provided with support rod 2 53, the top of support rod 2 53 is provided with pressure block 2 54, the end of support rod 2 53 is fixed with movable block 2 55, the end of movable block 2 55 is provided with support rod 3 56, the end of support rod 3 56 is provided with pressure block 3 57, and the bottom of support rod 3 56 is fixed with auxiliary support 58.

[0031] Pressure block 1 52 is fixed to the bottom of movable block 1 51 by bolts, pressure block 2 54 is fixed to the top of movable block 1 51 by bolts, and pressure block 3 57 is fixed to the end of movable block 2 55 by bolts.

[0032] Support rod 1 5 is placed between movable block 1 51 and pressure block 1 52, support rod 2 53 is placed between movable block 1 51 and pressure block 2 54, and support rod 3 56 is placed between movable block 2 55 and pressure block 3 57.

[0033] The top of the pitch balancing cylinder 33 is hinged to the connecting flange 31, and the output end of the bottom of the pitch balancing cylinder 33 is hinged to the column 3.

[0034] Specifically,

[0035] The guide support 42 and auxiliary support 58 are in direct contact with the workpiece and require soft protection to prevent scratching the workpiece.

[0036] The equipment has a floating function. After the front panel is fixed, the equipment load switches to be consistent with the weight of the front panel, so that the assistive robot is in a zero-gravity state. This allows the operator to better operate the equipment to move and position the front panel. After the front panel is fixed, the equipment has a gas and power failure protection function to prevent the equipment from falling due to sudden gas or power failure during operation.

[0037] Operate the brake button on the lifting control handle 12 to unlock the slewing joint brake. It should be noted that this equipment is a multi-joint articulated arm structure, and each joint is equipped with a pneumatic brake mechanism. When the equipment is not in use, all slewing joints must be locked to prevent accidental swinging.

[0038] Using the lifting control handle 12, the robotic arm is moved to the gripping area, aligned with the front panel, and the guide rest 42 is aligned with both sides of the front panel. At the same time, the two auxiliary supports 58 are lifted at the bottom of the front panel. The manual latch 11 is then inserted into the front panel to complete the connection and fixation between the robotic arm and the front panel.

[0039] Switch the equipment to load mode using the lifting control handle 12 and lift the front bulkhead. Move the equipment to the vehicle entry gap using the operating button handle 13. Adjust the angle of the robotic arm using the pitch balancing assembly 32 and pitch balancing cylinder 33 to provide a suitable swing amplitude for precise alignment with the vehicle body mounting position. It should be noted that the angle adjustment function of the pitch balancing assembly 32 and cylinder simultaneously improves the ease of picking up and placing the front bulkhead.

[0040] After the front panel is installed and fixed, disconnect the manual latch 11 from the front panel, and use the operation button handle 13 to completely detach the robot arm from the front panel. Then, use the operation button handle 13 to move the robot arm to the edge of the line, rotate it until it is parallel to the line, and place it back in the waiting position.

[0041] The auxiliary support 58 is used to support the bottom of the front bulkhead. It can be adjusted in multiple directions to adapt to front bulkheads of different sizes, ensuring support stability. The specific adjustment method is as follows:

[0042] Spacing adjustment (lateral): Move the movable block 51 laterally outside the support rod 5 to adjust the spacing between the two auxiliary supports 58; after adjusting to the appropriate position, tighten the bolts of the fixing block 52 to secure the movable block 51 to the support rod 5.

[0043] Front and rear position adjustment: Push the support rod 2 53 to drive the movable block 2 55 to move synchronously and adjust the front and rear position of the auxiliary support 58; after reaching the required position, tighten the bolts of the fixing block 2 54 to fix the position of the movable block 2 55.

[0044] Height adjustment (Z-axis): Move the support rod 3 56 up and down to drive the auxiliary support 58 to rise and fall synchronously, and adjust its Z-axis height; after adjusting to the target position, tighten the bolts of the fixing block 3 57 to complete the height fixation of the auxiliary support 58.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
