Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to an automated processing line for automotive oil cooler base plates. Background Technology

[0002] In the automotive parts manufacturing industry, the production of a single product requires multiple processes and equipment. A single machine can only complete a single step in the production process, limiting its functionality. After completing a step, the semi-finished product needs to be manually transferred to other equipment to continue the next production step. Completing the entire production process requires a series of different types of equipment and personnel, which reduces space utilization, increases the number of employees and equipment, and consequently increases production costs, hindering product efficiency and quality improvement.

[0003] If the various pieces of equipment required for product production are arranged in the order of production processes, then a robotic automation integration system can connect all the equipment, eliminating the need for manual intervention between the equipment. This not only reduces the manpower and material resources required for the entire production process, but also shortens the production cycle, improves production efficiency, reduces production costs, and ensures product quality.

[0004] Based on this, the present invention designs an automated processing line for automotive oil cooler base plates to solve the above problems. Summary of the Invention

[0046] In this invention, the automated line connects the forming module 200, cleaning module 300, dimension detection module 400, feeding module 500, finished product channel 600, and defective product channel 700. A robotic arm 120, driven by a ground rail 110, connects all the equipment for clamping, production, and transfer. A four-station transfer assembly 140 facilitates workpiece flipping to aid in production, enabling automatic loading and unloading, processing, cleaning, and online inspection of automotive oil cooler base plates. Drilling and tapping centers 1-210, 220, 3-230, and 4-240 work together to produce workpieces, increasing production efficiency, improving production stability, and reducing production costs. This results in high practical value and meets the needs of efficient and reliable production. Example 2

[0047] like Figure 7As shown, in a preferred embodiment of the present invention, the four-station transfer assembly 140 includes a material placement plate 141, a clearance slot 142, a first positioning pin 143, and an elastic clamping piece 144. The material placement plate 141 is fixedly installed on the moving end of the ground rail 110. Four sets of tooling are provided on the material placement plate 141. Each set of tooling is positioned by a plurality of first positioning pins 143 and elastic clamping pieces 144 fixedly installed on the material placement plate 141. Two clearance slots 142 are symmetrically opened on both sides of the material placement plate 141 to avoid the material transfer claw 130, so that the material transfer claw 130 can clamp the tooling from both sides of the material placement plate 141, thereby realizing the flipping of the workpiece. Example 3

[0048] like Figure 3 and 4 As shown, in a preferred embodiment of the present invention, the four-station hydraulic clamp 250 includes a positioning block 251, a side-pushing assembly 252, a first pressing assembly 253, and a first positioning seat 254. Four sets of first positioning seats 254 with dockable material-transferring jaws 130 are fixedly installed in each of the drilling and tapping centers 210, 220, and 330. Two positioning blocks 251 are fixedly installed on the first positioning seat 254. The two positioning blocks 251 on the first positioning seat 254 form a single-angle positioning of the workpiece, while the opposite sides each... A set of side-pushing components 252 is provided; several sets of rotatable and pressing first pressing components 253 are also provided around the first positioning seat 254; each station of the four-station hydraulic clamp 250 adopts a one-side two-sided positioning mode. The transfer gripper 130 of the robot 120 places four sets of workpieces on the first positioning seat 254 of the four-station hydraulic clamp 250 at one time. The side-pushing components 252 and the positioning blocks 251 cooperate to position the side of the workpiece. The first pressing components 253 flatten the workpiece against the plane of the first positioning seat 254 to achieve clamping and fixing of the workpiece.

[0049] The four-station hydraulic clamp 260 includes a second positioning pin, a second pressing component, and a second positioning seat. Four sets of second positioning seats for docking with the transfer jaws 130 are fixedly installed inside the drilling and tapping center 240. Each second positioning seat has two second positioning pins fixedly installed. Several sets of rotatable pressing second pressing components are also provided around the second positioning seats. Each station of the four-station hydraulic clamp 260 adopts a one-face two-pin positioning mode. The transfer jaws 130 of the robot arm 120 place four sets of workpieces on the second positioning seats of the four-station hydraulic clamp 260 at one time and achieve pre-positioning through the second positioning pins. Then, the second pressing component flattens the workpieces against the plane of the second positioning seat to achieve clamping and fixing of the workpieces.

[0050] The four drilling and tapping centers of the forming module 200 are all equipped with a fixed-point spray function, which, in conjunction with a high-flow water pump, promptly removes aluminum chips from the fixture surface, especially from the locating pins. It is also equipped with a tool breakage detection device, enabling it to interact with the controller of the robotic arm 120. Each first locating seat 254 and second locating seat is equipped with an airtightness detector. When the workpiece is flush with the plane of the locating seat 254, the airtightness detector determines whether the workpiece is properly clamped. If the workpiece is not properly clamped, the airtightness detector will sound an alarm, and the equipment will be unable to start. Example 4

The cleaning module 300 is equipped with positioning air blowing, high-pressure spraying, fixed-point air blowing and overall air blowing drying functions, so as to clean the workpiece more thoroughly.

[0052] The size detection module 400 is equipped with a laser range sensor to measure the plate thickness and the depth of the sealing groove. After cleaning, the workpiece is taken out by the robot arm 120 through the transfer gripper 130 and placed on the measuring fixture for automatic measurement. After the measurement result is judged, the robot arm 120 grabs it. Qualified products are neatly placed on the finished product channel 600 for discharge, and defective products are placed on the defective product channel 700 for rejection. Example 5

A fully loaded material frame 530 is conveyed from... The workpiece is fed into the rear end of the conveying mechanism 510 and moves on the conveying mechanism 510 until it is blocked by the baffle assembly 515. When the workpiece in the material frame 530 is emptied, the baffle assembly 515 no longer blocks the material frame 530. The material frame 530 slides into the receiving assembly 514. The receiving assembly 514 receives the material frame 530 and drives the material frame 530 to move vertically downward. The empty material frame 530 is placed on the transfer roller conveyor line 513. The transfer roller conveyor line 513 is started to move it to the return roller conveyor line 512. Under its own weight, the transfer roller conveyor line 513 slides to the rear end of the return roller conveyor line 512 to discharge the workpiece. Thus, the various parts of the conveying mechanism 510 cooperate to realize the automated feeding of workpieces and the automated discharge of empty material frames 530.

[0054] The material handling mechanism 520 includes a four-position material platform 521 and a material handling robot 522. The four-position material platform 521 and the material handling robot 522 are fixedly installed on the upper side of the upper frame roller conveyor line 511. The fixtures at each station of the four-position material platform 521 are inclined to facilitate the gripping of the material handling gripper 130 of the robot 120. The moving structure of the material handling robot 522 consists of linear modules of the Y-axis and Z-axis, and a rotary cylinder is fixedly installed at the moving end of the moving structure. A pneumatic gripper is fixedly installed at the moving end of the rotary cylinder to place the workpiece from the material frame 530 onto the fixtures at each station of the four-position material platform 521 according to a standard position. The worker only needs to load the blank with the stamped shape into the material frame 530. Different products are equipped with different material frames 530 according to the shape of the workpiece to prevent different parts from being loaded into the wrong container.
