Description

Technical Field

[0002] In the prior art, a utility model with application number 202223288187.9 discloses a bending and shaping device for the pins of chip tantalum capacitors. In order to solve the problem that the pins of chip tantalum capacitors are still generally bent manually, this bending method wastes time and is inefficient. In addition, since the bending parts of the capacitor pins cannot be highly unified, the heights after installation will also be uneven during later use. By providing a bending mechanism, the bending mechanism includes a mounting frame, a first screw rod, a first bevel gear, a lifting seat and a shaping plate, so that the capacitor pins can be quickly bent, replacing the traditional manual bending, and the height of the bending parts is unified, so that the installation height of the capacitor in later use can be kept consistent, which increases the aesthetics and improves the bending efficiency. By providing a shaping mechanism, the shaping mechanism includes a second screw rod, a sleeve, a shaping plate, a support frame and a support rod, so that the inclination angle of the capacitor pin is corrected, and the redundant pins are trimmed only after the angle is corrected, which can ensure that the length and height of the trimmed pins are consistent, which is more in line with the market demand.

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4As shown, this embodiment provides a bending and shaping device for chip tantalum capacitor terminals, including a base 1, a conveyor belt 2 located at the middle position of the top of the base 1 for conveying capacitors, and a capacitor fixing seat 3 located at the top of the conveyor belt 2 for limiting the capacitors, support rods 4 are vertically fixed on both sides of the top of the base 1, a hollow plate 5 is fixed between the tops of the support rods 4, a motor 6 is installed at the middle position of the top of the hollow plate 5, the output end of the motor 6 extends to the inside of the hollow plate 5, and a gear 7 is installed at the output end of the motor 6, and racks 8 are meshed and installed on both sides of the gear 7 , and the racks 8 are slidably arranged at both ends of the hollow plate 5, an L-shaped rod 9 is fixed to the end of the rack 8 away from the gear 7, the two sets of L-shaped rods 9 are symmetrical to each other, and a shaping mechanism 10 is provided at the end of the L-shaped rod 9 away from the rack 8, a first screw 11 is fixed at the middle position of the bottom of the gear 7, the first screw 11 penetrates to the bottom of the hollow plate 5 and is rotatably connected with the hollow plate 5, an inner screw tube 12 is threadedly installed at the bottom end of the first screw 11, and the inner screw tube 12 slides along the length direction of the first screw 11, and a bending block 13 is installed at the bottom end of the inner screw tube 12.

[0025] The overall working principle is as follows: when in use, first insert the chip tantalum capacitor to be bent and shaped into the capacitor fixing seat 3 so that the pin of the capacitor faces upward, and follow the capacitor conveyor belt 2 to move to the bottom of the bending block 13, and then start the motor 6 to control the first screw 11 at the bottom of the gear 7 to rotate. The first screw 11 rotates to control the inner screw tube 12 to move downward, and the bending block 13 moves downward and is inserted into the middle position of the two terminals, and the two terminals are bent in the conveying direction and the input direction respectively. At the same time, during the rotation of the gear 7, the horizontal sliding of the rack 8 is controlled to move the shaping mechanism 10 away from the capacitor. After bending, the motor 6 rotates in the opposite direction to control the rising and resetting of the inner screw tube 12. At this time, the gear 7 also rotates to control the translation of the rack 8. The two sets of shaping mechanisms 10 move toward each other, cut and shape the end of the terminal, and ensure that the end of the terminal is flush. After shaping, the motor 6 is controlled to rotate forward again to expand the spacing of the shaping mechanism 10, and the capacitor is conveyed. The above operations are repeated to continue processing and production.

[0026] In this embodiment, a limit block is fixed to the inner side of the rack 8 close to one end of the gear 7 , and the outer side of the rack 8 is attached to the side of the hollow plate 5 .

[0027] Partial working principle: During the sliding process of the rack 8, the use of the limit block can prevent the rack 8 from sliding out excessively, thereby ensuring the stability of the position of the rack 8.

[0028] In this embodiment, the cross-sectional view of the end of the base 1 is in an I-shape, and a non-slip pad is provided at the bottom of the base 1 .

[0029] Partial working principle: the base 1 is fixed on the ground, and the use of the protective pad increases the placement stability of the base 1.

[0030] In this embodiment, horizontal plates 14 are symmetrically fixed on both sides of the inner spiral tube 12 , and sliding rods 15 are vertically provided at both ends of the bottom of the hollow plate 5 . The sliding rods 15 penetrate the horizontal plates 14 and are slidably connected to the horizontal plates 14 .

[0031] Partial working principle: During the rotation of the first screw rod 11, since the sliding rod 15 passes through the horizontal plate 14 and is slidably connected to the horizontal plate 14, the position of the inner screw tube 12 is limited to ensure that the inner screw tube 12 can only be lifted vertically.

[0032] In this embodiment, the shaping mechanism 10 includes a vertical plate 16, a pruning knife 17 and a lifting mechanism. The vertical plate 16 is vertically fixed at the end of the L-shaped rod 9. The outer side of the vertical plate 16 is provided with a pruning knife 17 along the length direction. The vertical plate 16 is provided with a lifting mechanism for controlling the up and down movement of the pruning knife 17.

[0033] Local working principle: When the two groups of L-shaped rods 9 move toward each other, the trimming knives 17 on the vertical plate 16 will be driven to move simultaneously. The two groups of trimming knives 17 are located on the same horizontal plane, so the trimming knives 17 can cut and shape the terminals. According to the different reserved lengths of different capacitor terminals, the height of the trimming knives 17 can be controlled by the lifting mechanism, which is more practical.

[0034] In this embodiment, a rubber pad 18 is fixed to one side of the vertical plate 16 close to the trimming knife 17 . A through slot 19 is formed on the rubber pad 18 to match the trimming knife 17 . The thickness of the rubber pad 18 is greater than the height of the trimming knife 17 .

[0035] Partial working principle: When the two sets of vertical plates 16 move toward the terminal, the rubber pads 18 on the vertical plates 16 will first contact the terminal to squeeze and limit the terminal. During shaping, the rubber pads 18 are deformed due to squeezing, and the trimming knife 17 extends to the outside of the rubber pads 18 for shaping.

[0036] In this embodiment, the lifting mechanism includes a guide groove 20, a slider 21 and a second screw 22. The guide groove 20 is vertically opened on the outer side of the vertical plate 16. The slider 21 is slidably installed inside the guide groove 20. The pruning knife 17 is fixed on the slider 21. The second screw 22 is rotatably installed between the upper and lower ends of the guide groove 20. The second screw 22 passes through the slider 21 and is threadedly connected to the slider 21. An adjusting block is fixed to the top of the second screw 22.

[0037] Partial working principle: When adjusting the position of the trimming knife 17 , the second screw rod 22 is rotated to control the slider 21 to slide vertically inside the guide groove 20 , thereby controlling the position of the trimming knife 17 .

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
