[0017] like Figures 1 to 2 The diagram shows an automated return fixture splitting production line according to a preferred embodiment, which includes: a first conveyor line 1, a second conveyor line 2, a third conveyor line 3, a first robotic arm 4, a second robotic arm 24, a splitting platform 6, a drive device 5, a first servo press 10, and a second servo press 11.

[0018] The first conveyor line 1 and the third conveyor line 3 are connected by the material via the second conveyor line 2; the first conveyor line 1 is provided with a feeding position 14 and a first stacking position 13 in sequence along its reverse conveying path; the second conveyor line 2 is provided with a picking position 15 and a second stacking position 16 in sequence along its forward conveying path; at least one drive device 5 has a splitting platform 6 mounted on its output shaft, and the drive device 5 can drive the splitting platform 6 to switch between the feeding position 7, the first splitting position 8, the second splitting position 9 and the unloading position 23 in sequence; the first servo press 10 and the second servo press 11 are respectively close to the first splitting position 8 and the second splitting position 9; the first robotic arm 4 and the second robotic arm 24 are arranged between the splitting platform 6 and the first conveyor line 1.

[0019] Based on the above, this utility model also has the following embodiments: Furthermore, an automated return fixture splitting production line is provided, wherein the middle of the first conveyor line 1 and the beginning of the second conveyor line 2 are connected by a lifting mechanism 17.

[0020] Furthermore, an automated return fixture splitting production line further includes: a first lifting device 25; the first lifting device 25 is close to the first stacking position 13, and the first lifting device 25 is capable of lifting the second tray located at the first stacking position 13.

[0021] Furthermore, an automated return fixture splitting production line further includes: a second lifting device 26; the second lifting device 26 is located near the second stacking position 16, and is capable of lifting the first tray located at the second stacking position 16. Specifically, the first lifting device 25 and the second lifting device 26 can be composed of an electric cylinder and a clamping cylinder. The electric cylinder can lift the second tray and the first tray, and then the clamping cylinder clamps the second tray and the first tray. After that, the electric cylinder descends, so that the second tray and the first tray are no longer in contact with the first conveyor line 1 and the second conveyor line 2, and a space is left below for them to stay.

[0022] Furthermore, in an automated return fixture splitting production line, the tail end of the second conveyor line 2 and the head end of the third conveyor line 3 are connected by a first elevator 18.

[0023] Furthermore, an automated return fixture splitting production line is provided, wherein a second elevator 19 is provided at the tail end of the first conveyor line 1.

[0024] Furthermore, an automated return fixture disassembly production line is provided, wherein a fixture cleaning machine 20 is provided at the end of the third conveyor line 3.

[0025] Furthermore, an automated return fixture disassembly production line further includes: a receiving device 21, which is located near the unloading position 23, and a receiving box 22 is provided at the tail end of the receiving device 21.

[0026] In actual use, the first robotic arm 4 is equipped with grippers at its operating end to place the clamped reflow soldering fixture onto the splitting platform 6. The second robotic arm 24 is equipped with grippers and a suction cup at its operating end. The grippers can grasp the split signal pin positioning frame 102, DBC positioning frame 103, and reflow PINFIN carrier 105, while the suction cup can pick up the split pressure block 101, facilitating the handling of the various parts of the disassembled reflow soldering fixture. The first carrier tray holds the clamped reflow soldering fixture, and the second carrier tray holds the split reflow soldering fixture.

[0027] The overall workflow of this device is as follows; please refer to [link / reference] for details. Figure 1 and Figure 2 As shown: In actual use, the reflow soldering fixture conveyed by this device includes: a pressure block 101, a signal pin positioning frame 102, a DBC positioning frame 103, and a reflow PINFIN carrier 105. The pressure block 101, the signal pin positioning frame 102, and the DBC positioning frame 103 are fixed above the power module 104, and the reflow PINFIN carrier 105 is fixed below the power module 104.

[0028] Step 1: First, several clamped reflow soldering fixtures are placed on the first carrier tray. The first conveyor line 1 rotates clockwise, feeding the first carrier tray into it. The first conveyor line 1 transports the first carrier tray to the junction of the first conveyor line 1 and the second conveyor line 2. The lifting mechanism 17 lifts and feeds the first carrier tray into the second conveyor line 2. The second conveyor line 2 rotates clockwise (e.g., ...). Figure 1 (As indicated by the inner arrow) The first tray is conveyed to the pick-up position 15.

[0029] Step 2: The first robotic arm 4 grabs the reflow soldering fixture on the first tray located at the material picking position 15 and transfers the reflow soldering fixture to the splitting platform 6.

[0030] Step 3: When the first pallet is empty, the second conveyor line 2 continues to operate to transport the first pallet to the second stacking position 16, and the second lifting device 26 lifts the first pallet so that the first pallet does not come into contact with the second conveyor line 2.

[0031] Step 4: The splitting platform 6 receives the reflow soldering fixture transferred by the first robotic arm 4. At the loading position 7, the second robotic arm 24 splits the pressure block 101. Then, the splitting platform 6 moves to the first splitting position 8, where the first servo press 10 separates the signal needle positioning frame 102 from the rest. The splitting platform 6 returns to the loading position 7, where the second robotic arm 24 splits the signal needle positioning frame 102. The splitting platform 6 then moves to the second splitting position 9, where the second servo press 10 separates the DBC positioning frame 103 from the rest. The splitting platform 6 returns to the loading position 7, where the second robotic arm 24 splits the DBC positioning frame 103. The splitting platform 6 moves to the unloading position 23, where the gripper cylinder 12 removes the power module 104 and transports it to the receiving device 21. The receiving device 21 transfers the power module 104 to the receiving box 22. Finally, the splitting platform 6 returns to the loading position 7.

[0032] Step 5: Reverse the first conveyor line 1 (e.g.) Figure 1 (As shown by the inner arrow) and the second carrier tray is lifted by the second elevator 19 and sent to the unloading position 14 (as shown by the inner arrow). Figure 1 (As indicated by the inner arrow).

[0033] Step Six: The second robotic arm 24 places the disassembled pressure block 101, signal pin positioning frame 102, DBC positioning frame 103, and reflow PINFIN carrier 105 onto the first and second trays. After the first and second trays are full, the first conveyor line 1 continues to reverse to transport the full first and second trays to the first stacking position 13. The first lifting device 25 lifts the full first and second trays. Since the reflow soldering fixtures disassembled from one full first tray can hold three second trays, after three second trays are stacked at the first stacking position 13, the first conveyor line continues to reverse to move the stacked three second trays to the connection between the first and second conveyor lines 1 and then transfer them to the second conveyor line 2 via the lifting mechanism 17.

[0034] Step 7: The second conveyor line 2 rotates forward to convey the stacked three second carriers until they are stacked with the first carrier at the second stacking position 16 via the second lifting device 26.

[0035] Step 8: The second conveyor line 2 continues to transport the stacked first tray and the third tray via the first elevator 18 to the third conveyor line 3. The third conveyor line then rotates forward (e.g., ...). Figure 1 (As indicated by the inner arrow) It is conveyed to the fixture cleaning machine 20 for cleaning, and the first carrier, the second carrier, the pressure block 101, the signal pin positioning frame 102, the DBC positioning frame 103 and the return PINFIN carrier 105 are cleaned.

[0036] Step Nine: After the fixture cleaning machine 20 completes the cleaning, the third conveyor line 3 reverses, raising the first tray and the third tray via the first elevator 18 back to the previous process (e.g., Figure 1 (As indicated by the inner arrow).

[0037] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
