The pull rod 19 is fixedly mounted on the top of the pull plate 20. When the sleeve 14 moves downward along the outside of the positioning rod 13, the sleeve 14 can drive the vacuum cylinder 17 to move along the outside of the piston 18. The number of sleeves 14 is the same as the number of suction cups 11, and the bottom end of the sleeve 14 is connected to the suction cup 11 through a hose 21, so that the vacuum cylinder 17 moves along the outside of the piston 18 When moving downward, the air between the suction cup 11 and the bottom of the capacitor can be extracted through the hose 21, so that the suction cup 11 can adsorb the bottom of the capacitor, and the inner support plate 10 can cooperate with the suction cup 11 to firmly position the capacitor. After the capacitor is bent and shaped, the sleeve 14 is reset upward along the outer side of the positioning rod 13, so that the vacuum cylinder 17 moves upward along the outer side of the piston 18, and the air in the vacuum cylinder 17 is discharged, so that the suction cup 11 releases the capacitor, and the airflow is used to push the capacitor to separate from the placement plate 4. A retaining ring 33 is fixedly installed at the bottom of the sleeve 14, and the outer side of the hose 21 contacts the inner side of the retaining ring 33, so that the retaining ring 33 is against the outer side of the hose 21 to prevent the hose 21 from bending and winding. A protective grille 34 is fixedly installed on the top of the suction cup 11, so that the suction cup 11 adsorbs the bottom of the capacitor through the protective grille 34 to prevent dust and impurities from entering the suction cup 11.

[0024] Example 3: Please refer to Figure 2-Figure 8, this embodiment further illustrates other embodiments, the material fixing mechanism in the figure includes a pressure cylinder 12 fixedly mounted on the outside of the movable bracket 8, the pressure cylinder 12 can provide positioning for the capacitor, the material fixing mechanism also includes a pressure rod 22 fixedly mounted on the inner wall of the top of the pressure block 39, the pressure rod 22 is slidably mounted on the inner side of the pressure cylinder 12, the outer side of the pressure cylinder 12 is fixedly mounted with two symmetrically distributed sliding frames 23, the inner side of the sliding frame 23 is slidably mounted with a slide plate 24, the side of the slide plate 24 close to the pressure cylinder 12 is fixedly mounted with a card block 25, the card block 25 slides and extends to the inner side of the pressure cylinder 12, the outer side of the pressure rod 22 is provided with a card slot for the card block 25 to limit the insertion, and the bottom of the card block 25 is an inclined structure, the outer side of the pressure cylinder 12 is supported by two symmetrically distributed elastic slide bars 26 The outer side of the slide plate 24 is docked with the outer side of the slide plate 24. When the block 25 contacts the top of the pressure rod 22, the top of the pressure rod 22 can move along the inclined surface of the block 25, pushing the block 25 to move, so that the block 25 compresses the elastic slide bar 26 through the slide plate 24. When the block 25 is aligned with the slot on the pressure rod 22, the rebound force of the elastic slide bar 26 can be utilized to insert the block 25 into the slot of the pressure rod 22, and the pressure rod 22 is received in the pressure cylinder 12. A second spring 27 is fixedly installed between the top of the pressure rod 22 and the top inner wall of the pressure cylinder 12, and the elastic coefficient of the second spring 27 is greater than the elastic coefficient of the first spring 38. When the pressure block 39 contacts the top of the sleeve 14, the pressure block 39 compresses the second spring 27 through the pressure rod 22. Due to the elasticity of the second spring 27 The elastic coefficient is greater than the elastic coefficient of the first spring 38, so that the pressure block 39 can first press the sleeve 14 to move downward, and when the sleeve 14 cannot move, the pressure rod 22 continues to compress the second spring 27, and the block 25 can be inserted into the groove of the pressure rod 22 to position the pressure rod 22, so that the inner support plate 10 can support and position the capacitor between the upper mold 9 and the pin of the capacitor, and the upper mold 9 can smoothly and accurately contact the pin of the capacitor, and after the block 25 positions the pressure rod 22, the upper mold 9 and the pressure block 39 can synchronously move away from the capacitor to improve the material taking efficiency. A U-shaped roller 28 is fixedly installed on the side of the slide 24 away from the block 25, and two symmetrically distributed push rods 29 are provided on the outer side of the drive slide 7. The frame 7 is fixedly docked with the two push rods 29 through the fixed frame, and the two push rods 29 are respectively located above the two U-shaped rollers 28. The bottom ends of the push rods 29 are in an arc-shaped structure, so that when the movable bracket 8 drives the pressing cylinder 12 to reset upward, the push rod 29 can contact the U-shaped roller 28, so that the push rod 29 pulls the slide plate 24 to move through the U-shaped roller 28, and the block 25 can move away from the slot on the pressure rod 22. The rebound force of the second spring 27 is used to make the pressure rod 22 drive the pressure block 39 to reset. Two vertically distributed sliding columns 35 are fixedly installed on both sides of the pressure rod 22. A guide groove for the sliding column 35 to limit the sliding of the sliding column 35 is provided on the outer side of the pressure cylinder 12, so that the pressure rod 22 can drive the sliding column 35 to move along the guide groove of the pressure cylinder 12, thereby improving the stability of the movement of the pressure rod 22.The outer side of the pressure rod 22 is provided with a long groove for the limited sliding of the card block 25, so that the card block 25 can be inserted into the card slot of the pressure rod 22 along the long groove, providing a guide for the docking of the card block 25 and the card slot.

[0025] Working principle: First, the staff puts the capacitor on the placement plate 4, the inner support plate 10 is on the inner side of the capacitor, and the pin of the capacitor contacts the top of the lower mold 5. At this time, the staff starts the driving slide 7 by driving the main machine 2. The driving slide 7 drives the movable bracket 8 to move downward, so that the movable bracket 8 drives the upper mold 9 and the pressing cylinder 12 to move synchronously. The pressing cylinder 12 pushes the pressing rod 22 to move synchronously through the second spring 27, so that the pressing block 39 at the bottom of the pressing rod 22 contacts the top of the sleeve 14. Since the elastic coefficient of the second spring 27 is greater than the elastic coefficient of the first spring 38, the pressing block 39 presses the sleeve 14 to move downward, and the sleeve 14 compresses the first spring 38 and drives the positioning plate 36 to move downward, and the positioning plate 36 pushes the two connecting rods 16 to move synchronously , two parallel connecting rods 16 push the slider 37 on the mounting plate 15 to move along the slide groove on the placement plate 4 and the outer side of the optical axis, so that the mounting plate 15 pushes the inner support plate 10 to contact the inner side of the capacitor through the third spring 31. The elasticity of the third spring 31 is used to make the inner support plate 10 elastically support the inner side of the capacitor. At the same time, the sleeve 14 moves downward along the outer side of the positioning rod 13, and drives the vacuum cylinder 17 to move downward along the outer side of the piston 18, so that the vacuum cylinder 17 extracts the air between the suction cup 11 and the bottom of the capacitor through the hose 21, fixing the capacitor on the placement plate 4, and the inner support plate 10 can cooperate with the suction cup 11 to firmly position the capacitor. At this time, the sleeve 14 completely compresses the first spring 38, and the sleeve 14 is used to compress the pressure The reaction force of the block 39 causes the pressure block 39 to compress the second spring 27 through the pressure rod 22. At the same time, the pressure rod 22 moves along the inner side of the pressure cylinder 12, and the top end of the pressure rod 22 contacts the inclined surface of the card block 25, so that the pressure rod 22 pushes the card block 25 to move, and the card block 25 pushes the slide plate 24 to move along the inner side of the slide frame 23 and compresses the elastic slide bar 26. When the card block 25 is aligned with the card slot on the pressure rod 22, the elastic slide bar 26 is used to utilize the rebound force of the elastic slide bar 26 to insert the card block 25 into the card slot of the pressure rod 22. At this time, the upper mold 9 contacts the pin of the capacitor, so that the upper mold 9 cooperates with the lower mold 5 to stably position the capacitor pin. Subsequently, the main machine 2 is driven to start the bending part 6, so that the bending part 6 bends and shapes the pin, and then the bending part 6 rotates to reshape the pin. The upper mold 9 is moved away from the bent and shaped pins. At the same time, the pressing cylinder 12 pulls the pressing rod 22 to move synchronously through the block 25, so that the pressing block 39 is away from the sleeve 14. The sleeve 14 is reset upward along the outer side of the positioning rod 13 by the rebound force of the first spring 38. The inner support plate 10 can be away from the inner side of the capacitor, and the vacuum cylinder 17 moves upward along the outer side of the piston 18, so that the piston 18 discharges the air sucked in the vacuum cylinder 17. The air is discharged from the suction cup 11 through the hose 21. The airflow discharged from the suction cup 11 is used to push the bottom of the capacitor to separate the capacitor from the placement plate 4, and the pins of the capacitor can be separated from the lower mold 5. Finally,The staff took out the capacitors on the placement plate 4, thus achieving the effect of stable positioning and rapid material removal, improving the processing efficiency of the capacitors.
