[0042] By adopting the above technical solution, the inductor product is held in place by the transfer groove 147, and the transfer plate 148 is moved horizontally by the transverse transfer cylinder 145, thereby moving the inductor product between various workstations.

[0043] Specifically, the shaping component 6 includes a gripper cylinder 61, a pressing shaping cylinder 62, and a translating cylinder 64. The gripper cylinder 61 and the translating cylinder 64 are arranged opposite to each other. A shaping clamping block 66 is installed on the output end of the gripper cylinder 61.

Then, the pressing shaping cylinder 62 drives the shaping pressure block 63 to press the inductor product's pins onto the translation slider 65, thereby shaping the inductor product's pins up and down.

[0045] Specifically, the bending assembly 8 includes a bending lifting cylinder 81, a bending lifting block 82 is installed on the output end of the bending lifting cylinder 81, two opposing roller moving cylinders 84 are installed on both sides of the upper end of the bending lifting block 82, and rollers 83 are installed on the output end of the roller moving cylinders 84.

[0046] By adopting the above technical solution, the roller moving cylinder 84 drives the roller 83 to extend, and then the bending lifting cylinder 81 drives the bending lifting block 82 to descend, thereby realizing the first 90° bend of the pin.

[0047] Specifically, the cutting and bending assembly 12 includes two cutting and bending cylinders 121 symmetrically arranged on both sides of the transfer track 13. A slide block 122 is mounted on the output end of each cutting and bending cylinder 121. A cutting head 125, a pre-bending head 124, and a final bending head 123 are sequentially connected to the slide block 122. The end of the pre-bending head 124 has a 45° chamfer. The transfer track 13 has a cutting clearance groove 132 corresponding to the cutting head 125.

[0049] Specifically, the flattening assembly 9 includes a flattening cylinder 91, and a flattening block 92 is installed on the output end of the flattening cylinder 91.

The fourth material transfer groove 147 corresponds to the cutting station.

[0053] By adopting the above technical solution, during the cutting action, the pressing cylinder 142 drives the pressing block 149 to press down the inductor product, thereby avoiding the cutting size deviation caused by the inductor product jumping during the cutting process.

[0054] Example 3

[0055] The difference between this embodiment and embodiment 1 is that, specifically, a height limit block 101 is installed on the feeding guide rail 10, and a proximity sensor 102 is installed on the upper side of the height limit block 101. The proximity sensor 102 is connected to the PLC controller signal. When the proximity sensor 102 can still detect inductance after a set time, it indicates that there is a product with excessive height. Then, an alarm message is issued through a buzzer to remind the staff to remove the product with excessive height.

[0056] By adopting the above technical solution, the height-limiting block 101 blocks the inductor products that exceed the height limit, thereby eliminating the products that exceed the height limit.

[0057] All cylinders in this invention are equipped with solenoid valves on their air ends, and the solenoid valves are connected to the PLC controller via signals.

[0058] The working steps of this utility model are as follows:

[0059] 1. The inductor products are conveyed to the material tray 3 by the vibratory feeder 1, and the inductor products are transported to the unloading table 43 by the spider robot 2;

[0060] 2. The pusher cylinder 45 drives the pusher block 44 to push the inductor products on the feeding platform 43 onto the feeding guide rail 42. Under the action of the direct vibrator 41, the inductor products are conveyed backward along the feeding guide rail 42 to the top of the distribution block 72.

[0061] 3. The material distribution cylinder 71 drives the material distribution block 72 to lift upward, lifting the inductor products above the material distribution block 72 until they are flush with the material transfer track 13;

[0062] 4. The lifting cylinder 144 drives the transfer plate 148 to descend to the set position, the transfer groove 147 holds the inductor product, and then the horizontal transfer cylinder 145 drives the transfer plate 148 to move one station position, moving the inductor product on the material distribution block 72 into the material groove on the horizontal transfer slider 65.

[0063] 5. The translation cylinder 64 pushes the translation slider 65 to move the inductor product between the two shaping clamps 66. The gripper cylinder 61 drives the two shaping clamps 66 to clamp and close, thereby shaping the two sides of the inductor product's pins. Then, the pressing shaping cylinder 62 drives the shaping pressure block 63 to press the inductor product's pins onto the translation slider 65, thereby shaping the inductor product's pins up and down. Then, the translation cylinder 64 drives the translation slider 65 to reset.

[0064] 6. The transverse cylinder 145 continues to drive the transfer plate 148 to move one station position, moving the inductor product to the first bending station. The roller moving cylinder 84 drives the roller 83 to extend, and then the bending lifting cylinder 81 drives the bending lifting block 82 to descend, realizing the first 90° bend of the pin.

[0065] 7. The horizontal movement cylinder 145 continues to drive the transfer plate 148 to move one station position, moving the inductor product to the cutting station. The cutting and bending cylinder 121 drives the slide 122 to extend. The two cutting heads 125 cooperate with the transfer track 13 to cut off the excess pins. Then the cutting and bending cylinder 121 is reset.

[0066] 8. The horizontal movement cylinder 145 continues to drive the transfer plate 148 to move one station position, moving the inductor product to the pre-bending station. The cutting and bending cylinder 121 drives the slide 122 to extend. The pins are pre-bent through the two pre-bending heads 124 and the transfer track 13. Then the cutting and bending cylinder 121 is reset.

[0067] 9. The horizontal movement cylinder 145 continues to drive the material transfer plate 148 to move one station position, moving the inductor product to the final bending station. The cutting and bending cylinder 121 drives the slide 122 to extend. Through the cooperation of the two final bending heads 123 and the material transfer track 13, the pin is bent 90° for the second time. Then the cutting and bending cylinder 121 is reset.

[0068] 10. The flattening cylinder 91 drives the flattening block 92 to move upward and flatten the bent pin;

[0069] 11. The transverse cylinder 145 continues to drive the transfer plate 148 to move one station position, pushing the inductor product with completed pin bending onto the unloading guide rail 10;

[0070] 12. The inductor product slides into the receiving box 11 via the feeding guide 10. If the proximity sensor 102 can still detect the inductor after a set time, it indicates that there is a product with excessive height. An alarm message will be issued through the buzzer to remind the staff to remove the product with excessive height.

[0071] In summary, this invention achieves automated feeding, lead shaping, lead bending, and unloading of inductor products, with a high degree of automation, reducing the labor intensity of workers and improving the efficiency of lead bending. Through the shaping component 6, this invention achieves shaping of the inductor product leads on both sides and vertically, preventing lead misalignment and thus avoiding defective products with electrode deviations. During the cutting process, the pressing cylinder 142 drives the pressing block 149 to hold the inductor product in place, preventing dimensional deviations caused by product movement during cutting. The height-limiting block 101 blocks inductor products exceeding the height limit, thus eliminating oversized products.
