Abstract
Description
Technical Field
[0001] This utility model relates to the field of production line technology, and in particular to a subframe ground rail type automatic processing line. Background Technology
[0002] The front subframe, as one of the components of a car chassis, is a key component of the entire car. It not only supports the engine and transmission, but also has the function of shock absorption and collision protection. At the same time, it plays an important role in the handling and driving performance of the entire car.
[0003] However, these subframes require processing and manufacturing during use. In order to improve the efficiency of processing and manufacturing, they need to be processed quickly on the production line. However, the processing time required for different processing positions on the existing production line varies. For example, fine processing takes a long time and requires waiting for the previous station to complete before continuing, which wastes waiting time. Some stations require manual assistance, which poses safety hazards and is inefficient. Utility Model Content
[0004] To address the aforementioned technical problems, a subframe-mounted automatic processing line is provided. This line utilizes a six-axis robot with a dual-claw structure to simultaneously pick up finished products and place unfinished products, saving product handling time. By automating the material handling process, manual labor is replaced, reducing labor costs and improving processing efficiency.
[0005] To achieve the above objectives, this utility model discloses a subframe ground rail type automatic processing line, including linearly arranged unit processing lines. One side of each unit processing line is equipped with a conveyor line perpendicular to the unit processing line, and the other side of each unit processing line is equipped with a discharge port and a grinding platform. The unit processing line includes a roughing station, a finishing station, and a post-processing station in sequence along the direction from the conveyor line to the discharge port. Two six-axis robots are installed in front of each unit processing line on a horizontal ground rail. The six-axis robots perform alternating operations between the unit processing lines.
[0006] Furthermore, the six-axis robot includes a first robot positioned in front of the roughing station, which moves between the conveyor line and the roughing station. A second robot is positioned in front of the finishing station and the post-processing station, and moves on a horizontal track between the finishing station and the post-processing station.
[0007] Furthermore, the six-axis robot has a dual-claw structure.
[0008] Furthermore, a flipping platform is provided on the side of the horizontal ground rail away from the unit processing line, located between the roughing station and the finishing station.
[0009] Furthermore, the finishing station consists of two machine tools arranged side by side.
[0010] Furthermore, the conveyor line is provided with up to five carrier plates for supporting the subframe, and a robot gripping position is provided on the side of the conveyor line near the roughing station.
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model discloses a sub-frame ground rail type automatic processing line. Products are manually moved from the material frame to the conveyor plate, automatically transferred to the six-axis robot's picking position, and automatically gripped for processing in rotation between processing equipment. Finished products are returned to the high-speed line plate and automatically laser-engraved. The products are then returned to the manual operation position for manual deburring and manual loading into frames. The design, operation, and maintenance of the equipment and facilities must fully consider personnel safety and meet ergonomic requirements to minimize the labor intensity of operators.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] One embodiment of this utility model is as follows: Figure 1As shown, a conveyor line 1 is installed on one side of the unit processing line, perpendicular to it. A discharge port and a grinding platform are set on the other side of the unit processing line. The unit processing line includes a roughing station 2, a finishing station 3, and a post-processing station 4 along the direction from the conveyor line 1 to the discharge port. The unit processing line performs multiple processing steps such as milling and drilling on the blank to obtain the finished subframe. Two six-axis robots are installed in front of the unit processing line and mounted on horizontal rails 5. The six-axis robots perform alternating operations between the unit processing lines. With the double-claw structure of the six-axis robots, the finished products in the equipment can be grabbed at the same time, and the unfinished products can be put down, saving product handling time. The automated handling and circulation of the processing line replaces manual labor, reducing labor costs and improving processing efficiency.
[0017] The six-axis robot includes a first robot 6 positioned in front of the roughing station 2, which moves between the conveyor line 1 and the roughing station 2. A second robot 7 is positioned in front of the finishing station 3 and the post-processing station 4, which moves on the horizontal ground rail 5 between the finishing station 3 and the post-processing station 4.
[0018] The six-axis robot has a dual-claw structure. It first grabs the finished product from the equipment, and then puts the unprocessed product on the claw into the processing equipment. The equipment then starts automatically to perform the processing operation.
[0019] A flipping platform is set on the side of the horizontal ground rail 5 away from the unit processing line, located between the roughing station 2 and the finishing station 3. The flipping platform is not shown in the attached figure. After the first robot finishes processing at the roughing station, it places the product in the flipping platform as a transfer station. After the product is automatically positioned, the second robot moves to the platform and automatically picks up the product and places it on the empty finishing station.
[0020] The finishing station 3 consists of two machine tools arranged side by side, which simultaneously finish two products. By using staggered processing times, waiting time is reduced, thereby improving processing efficiency.
[0021] The conveyor line 1 has up to five carrier plates for supporting the subframe. A robot gripping position is set on the side of the conveyor line 1 near the rough processing station 2. The operator takes the product from the material box and places it into the carrier plate of the conveyor line. When the release button is pressed, the photoelectric sensor detects that there is a product on the carrier plate. The proximity switch under the carrier plate detects that the product has arrived. The light curtain is not blocked. The carrier plate is automatically released to the robot gripping position. The robot gripping position has a blocking component to block the carrier plate in the incoming direction.
[0022] The working principle of this embodiment is as follows: Specifically, two workers are required at the conveyor line and the discharge port. They manually take products from the material box and place them on the conveyor line carrier plate. Pressing the release button activates the photoelectric sensor, which detects the product on the carrier plate. A proximity switch below the carrier plate detects the product's arrival and ensures the light curtain is not obstructed. The carrier plate automatically flows to the robot's gripping position. Once the carrier plate reaches the robot's gripping position, the robot automatically picks up the products and sequentially places them into the pre-set processing equipment for processing. The gripper is a double-claw design; it first picks up the finished products from the equipment, then places the unprocessed products from the claws into the processing equipment. The equipment then automatically starts. The system automatically performs processing operations. After the first robot completes the rough processing at the first robot station, it places the product on the product flipping platform, where the product is automatically positioned. The second robot then moves to the flipping platform to automatically grab the processed product at the fine processing station and places the unprocessed product into the equipment. The equipment then automatically starts processing. After the fine processing at the first robot station is completed, the second robot moves to the post-processing station to grab the processed product and places the unprocessed product into the equipment. The equipment then automatically starts processing. The second robot places the finished product into the empty discharge plate. The automatic cycle time is 300 seconds (including loading and unloading).
