Description

Technical Field

[0001] This utility model relates to the technical field of oil cooler fin processing equipment, and in particular to a collection device for oil cooler fins after stamping. Background Technology

[0002] Combination Figure 1 The diagram shows the structure of the oil cooler fins after stamping. The oil cooler fins are thin plate structures with arc-shaped notches at the four corners and an open slot in the middle.

[0003] In the existing stamping process, after the oil cooler fins are stamped, they slide from the guide groove at the tail of the press into the material frame. The fin material is scattered and disordered, which has the following impact on subsequent processes: (1) The next process is to clean the oil stains on the surface of the fins. During cleaning, the fins need to be neatly arranged. The disordered fins need to be sorted and aligned manually. Manual stacking is time-consuming and laborious. In addition, the manual stacking process is a waste of personnel.

[0004] (2) The fins that slide down from the guide groove are messy, which is not conducive to manual material handling. At the same time, the messy material box is prone to damaging the fins.

[0005] (4) In the core assembly process, it is necessary to strictly control the front and back of the fins and the orientation of the slots. If the fins are placed in the wrong direction, the assembled core is easy to be scrapped. Since the material is sorted manually, it is impossible to guarantee that the fin orientation is 100% correct.

[0006] Therefore, there is an urgent need to provide a collection device for the stamped oil cooler fins, which can stack and arrange the stamped oil cooler fins to overcome the shortcomings of existing equipment. Utility Model Content

[0054] The method of using the above-mentioned collection device includes the following steps: S1. After the punch press 1 finishes punching the oil cooler fins, the gripper on the gripper mechanism 4 moves to the right to the material picking position to pick up the formed oil cooler fins and moves the oil cooler fins to directly above the hopper mechanism 3. S2. The grippers on the gripper mechanism 4 release the oil cooler fins, and the oil cooler fins are stacked in the hopper mechanism 3 in a stacked manner. S3. The gripper on the gripper mechanism 4 moves back to the right to the material picking position. While the gripper waits for the next gripping, the pressing and straightening mechanism 6 presses down and straightens the oil cooler fins in the hopper mechanism 3. After the straightening is completed, the pressing and straightening mechanism 6 resets.

[0055] S4. Repeat steps S1 to S3 to perform the next fin stacking operation.

[0056] Specifically, fin stacking includes the following four processes: Process 1: After the punch press 1 finishes punching the oil cooler fins, the gripper moving module 402 first drives the pneumatic gripper 403 to move to the right to the gripping position, first gripping the oil cooler fins. Then, under the driving action of the gripper moving module 402, the pneumatic gripper 403 is driven to move to the left, and the oil cooler fins are moved to the position directly above the two fin placement positions of the hopper mechanism 3.

[0057] Step 2: Discharging material from the silo. For example... Figure 9 As shown, the process is as follows: (1) The pneumatic gripper 403 is moved to the top of the fin placement station; (2) The piston rod of the thin cylinder 407 descends, allowing the fins to enter the fin placement station formed by the four columns 310 for pre-positioning; (3) Pneumatic gripper 403 gripper chamber with open fins; (4) The pneumatic gripper 403 moves slightly to the left to avoid the fins; (5) The piston rod of the thin cylinder 407 moves upward and resets; (6) The pneumatic gripper 403 moves to the right to the material picking position; (7) While the pneumatic gripper 403 is waiting for the next gripping, the piston rod of the second cylinder 602 extends and drives the pressure block 605 to move down, pressing the fins into the fin placement station formed by the four columns 310; after the pressing is completed, the piston rod of the second cylinder 602 moves up to reset.

[0058] Process 3: Silo stacking.

[0059] Combination Figure 8 As shown, each time a fin is placed, the second servo motor 502 of the material support compensation mechanism 5 drives the second lead screw to rotate, thereby causing the fin support plate 510 to move downward by one fin thickness, thus forming layers stacked and always at a reasonable height until the hopper is full.

[0060] Process 4: Transfer of silo components.

[0061] Combination Figure 7 As shown, the hopper mechanism 3 is equipped with two hopper components. When the first hopper component is full, the system switches to the second hopper component to collect the material, and the worker can then take away the material from the first hopper component. Similarly, when the second hopper component is full, the system switches to the first hopper component to collect the material, and the worker can then take away the material from the second hopper component.
