Description

Technical Field

[0001] The utility model relates to the technical field of capacitor leg cutting, in particular to a cylindrical capacitor leg cutting device. Background Art

[0002] A capacitor is a common component for storing electric charge and electrical energy. A cylindrical capacitor is a common type of capacitor, which includes a body and two leads. The body mainly includes two conductors close to each other, with a layer of non-conductive insulating medium sandwiched between the two conductors, and the two conductors are electrically connected to the two leads respectively. During the production process of the cylindrical capacitor, the leads are reserved relatively long. Therefore, when using the cylindrical capacitor, it is necessary to first cut the too-long leads to an appropriate length.

[0003] In the prior art, usually, the uncut cylindrical capacitors are conveyed onto the leg cutting track of the leg cutting machine. The uncut cylindrical capacitors move on the leg cutting track until they reach the cutting tool of the leg cutting machine. The cutting tool cuts the leads of the uncut cylindrical capacitors. The cut cylindrical capacitors are then continuously conveyed by the leg cutting track into a placement box. The placement box is generally placed below the outlet end of the leg cutting track. The cut cylindrical capacitors fall from the outlet end of the conveying track into the placement box. However, in actual processing, the number of cylindrical capacitors is large, and a large number of cut cylindrical capacitors are stacked in the placement box, making it necessary to further arrange the cut cylindrical capacitors neatly later. Summary of the Utility Model

[0004] In order to solve the deficiencies of the prior art, the utility model provides a cylindrical capacitor leg cutting device, which enables the cylindrical capacitors to be neatly arranged in the placement box.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a cylindrical capacitor leg cutting device, including a leg cutting machine for cutting the leads of the cylindrical capacitor, a plurality of placement boxes for carrying the cut cylindrical capacitors, and a belt conveyor for conveying all the placement boxes. A guiding cylinder is fixedly connected to the outlet of the leg cutting track of the leg cutting machine, and the placement box can pass under the guiding cylinder during movement. A through groove for the cylindrical capacitor to enter is opened on the surface of the guiding cylinder close to the leg cutting track. The length direction of the placement box is consistent with the conveying direction of the belt conveyor. A plurality of vertically arranged partition plates are evenly distributed along the length direction of the placement box. An accommodating space is formed between adjacent partition plates, and the accommodating space is used to accommodate the cut cylindrical capacitors. The cut cylindrical capacitors can enter the guiding cylinder through the through groove and fall downward into one of the accommodating spaces.

[0006] As a further optimization of a cylindrical capacitor leg trimming device of the utility model: a horizontal partition board is arranged in the placement box, and all the partition boards are vertically arranged on the partition board. The partition board divides the placement box into an upper layer and a lower layer. The partition board and the partition boards together form the accommodating space. A plurality of through holes are opened in the partition board along its length direction, and the through holes are in one-to-one correspondence with the accommodating space and communicate with it. The aperture of the through hole is smaller than the diameter of the cylindrical capacitor, so that when the cylindrical capacitor falls into the accommodating space, the legs of the cylindrical capacitor can enter the corresponding through holes.

[0007] As a further optimization of a cylindrical capacitor leg trimming device of the utility model: two flexible limiting strips are fixedly arranged on the upper surface of the belt of the belt conveyor, and the two limiting strips extend along the length direction of the belt conveyor. The distance between the two limiting strips is the same as the width of the placement box.

[0008] As a further optimization of a cylindrical capacitor leg trimming device of the utility model: a plurality of connecting strips are connected between the two limiting strips. All the connecting strips are distributed along the conveying direction of the belt conveyor, and the length direction of all the connecting strips is perpendicular to the conveying direction of the belt conveyor. A plurality of placement spaces for placing the placement box are formed between the two limiting strips and all the connecting strips. A channel is opened on the side wall of the placement box close to the connecting strip, and the extending direction of the channel is the same as the length direction of the connecting strip. When the placement box is placed in the placement space, the channels of two adjacent placement boxes can be attached to the surface of the corresponding connecting strip.

[0009] As a further optimization of a cylindrical capacitor leg trimming device of the utility model: two opposite arc-shaped protrusions are arranged on the inner wall of the guiding cylinder close to its outlet. The minimum distance between the two arc-shaped protrusions is greater than the diameter of the cylindrical capacitor.

[0010] As a further optimization of a cylindrical capacitor leg trimming device of the utility model: an inwardly concave arc-shaped area is arranged on the inner wall of the guiding cylinder close to the leg trimming track, and the arc-shaped area is close to the inlet end of the guiding cylinder.

[0011] As a further optimization of a cylindrical capacitor leg trimming device of the utility model: the distance between the inner wall of the guiding cylinder far from the leg trimming track and the leg trimming track is less than the height of the cylindrical capacitor.

[0012] As a further optimization of a cylindrical capacitor leg trimming device of the utility model: a mounting plate is installed at the inlet end of the guiding cylinder, and the mounting plate is connected to the leg trimming track by bolts.

[0013] Beneficial effects: A guiding cylinder is fixedly connected to the outlet of the leg-cutting track of the leg-cutting machine of the present utility model, and the placement box can pass under the guiding cylinder during the moving process. A plurality of vertically arranged partition plates are evenly distributed along the length direction of the placement box, and accommodation spaces are formed between adjacent partition plates. The cut cylindrical capacitors can enter the guiding cylinder through the through slots and fall downward into one of the accommodation spaces, so that the cut cylindrical capacitors can be placed in the placement box orderly.

[0018] The technical solutions of the present utility model will be further elaborated in detail below in combination with specific embodiments. For parts not detailedly recorded and disclosed in the following embodiments of the present utility model, they should all be understood as the prior art known or should be known to those skilled in the art, such as the model, specific structure of the leg-cutting machine 1 and how to cut the legs of the cylindrical capacitor 2, how the cylindrical capacitor 2 is conveyed onto the leg-cutting track 101 of the leg-cutting machine 1, the cooperation between the leg-cutting track 101 and the leg-cutting machine 1, the model of the cylindrical capacitor 2, the model of the belt conveyor 4, etc.

[0019] Embodiment 1

[0020] A cylindrical capacitor leg-cutting device, as Figure 1 and Figure 2As shown in the figure, it includes a leg cutter 1 for cutting the pins of the cylindrical capacitor 2, a plurality of placement boxes 3 for carrying the cut cylindrical capacitors 2, and a belt conveyor 4 for conveying all the placement boxes 3. A guide cylinder 102 is fixedly connected to the outlet of the leg cutting track 101 of the leg cutter 1, and the placement box 3 can pass under the guide cylinder 102 during its movement. After the pins of the cylindrical capacitor 2 are cut by the leg cutter 1, the leg cutting track 101 continues to convey the cut cylindrical capacitor 2 and move along the leg cutting track 101 until it moves to the outlet of the leg cutting track 101 and falls. Due to inertia during the fall, the top of the cylindrical capacitor 2 will tilt towards the direction of the outlet of the leg cutting track 101, and the top of the cylindrical capacitor 2 will hit the end of the inlet end of the guide cylinder 102. At the same time, the leg cutting track 101 continuously conveys the cylindrical capacitor 2 to move, and the adjacent cylindrical capacitor 2 behind will squeeze this tilted cylindrical capacitor 2, pushing it completely out of the leg cutting track 101 and making it fall from the leg cutting track 101.

[0021] A through groove 103 for the cylindrical capacitor 2 to enter is opened on the surface of the guide cylinder 102 close to the leg cutting track 101. In this way, when the cut cylindrical capacitor 2 falls, it will not be hindered by the side wall of the guide cylinder 102 close to the leg cutting track 101. The length of the through groove 103 extending downward is about one-fourth of the guide cylinder 102. If it is too long, it cannot ensure that the cut cylindrical capacitor 2 can smoothly fall from the outlet of the guide cylinder 102, and it may directly fall out of the guide cylinder 102 and cannot fall into the accommodation space 303. The length direction of the placement box 3 is consistent with the conveying direction of the belt conveyor 4. A plurality of vertically arranged partition plates 301 are evenly distributed along the length direction of the placement box 3. An accommodation space 303 is formed between adjacent partition plates 301, and the accommodation space 303 is also formed between the partition plates 301 close to both ends of the placement box 3 and the adjacent inner walls of the placement box 3. The accommodation space 303 is used to accommodate the cut cylindrical capacitor 2. The cut cylindrical capacitor 2 can enter the guide cylinder 102 through the through groove 103 and fall downward into one of the accommodation spaces 303. Specifically, how to control the belt conveyor 4 to convey the placement box 3 so that the cut cylindrical capacitor 2 can fall downward into one of the accommodation spaces 303 is conventional prior art in this field and will not be elaborated too much here. In this way, when the cut cylindrical capacitor 2 falls, it can fall into the accommodation space 303 of the placement box 3 in an orderly manner and will not be randomly stacked in the placement box 3.

[0022] The above is the basic implementation mode of the present utility model. Further improvements, optimizations and limitations can be made on this basis to obtain the following various embodiments:

[0023] Embodiment 2

[0024] This embodiment is an improved solution based on Embodiment 1. Its main structure is the same as that of Embodiment 1. The improvement lies in that: as Figure 2 shown, since the pins of the cylindrical capacitor 2 will face downward when falling, in order to avoid damage to the pins, a horizontal partition plate 302 is provided in the placement box 3. All the partition plates 301 are vertically arranged on the partition plate 302. The partition plate 302 divides the placement box 3 into an upper layer and a lower layer. The placement box 3 does not need to be provided with a bottom. The partition plates 301 and the partition plate 302 together form the accommodation space 303. A plurality of through holes 3021 are formed in the partition plate 302 along its length direction. The through holes 3021 communicate with the accommodation space 303 one by one. The diameter of the through holes 3021 is smaller than the diameter of the cylindrical capacitor 2, so that when the cylindrical capacitor 2 falls into the accommodation space 303, the pins of the cylindrical capacitor 2 can enter the corresponding through holes 3021.

[0025] Embodiment 3

[0026] This embodiment is an improved solution based on Embodiment 2. Its main structure is the same as that of Embodiment 2. The improvement lies in that: as Figure 2 shown, in order to ensure the accurate placement position of the placement box 3 on the belt conveyor 4, two flexible limit strips 401 are fixedly arranged on the upper surface of the belt of the belt conveyor 4, and the two limit strips 401 extend along the length direction of the belt conveyor 4. The distance between the two limit strips 401 is the same as the width of the placement box 3.

[0027] Embodiment 4

[0028] This embodiment is an improved solution based on Embodiment 3. Its main structure is the same as that of Embodiment 3. The improvement lies in that: as Figure 2 shown, in order to place the placement box 3 more accurately on the belt conveyor 4, a plurality of connecting strips 402 are connected between the two limit strips 401. All the connecting strips 402 are distributed along the conveying direction of the belt conveyor 4, and the length direction of all the connecting strips 402 is perpendicular to the conveying direction of the belt conveyor 4. A plurality of placement spaces for placing the placement box 3 are formed between the two limit strips 401 and all the connecting strips 402. In order to avoid too large a distance between the placement boxes 3, the thickness of the placement box 3 is relatively thin. A channel 304 is opened on the side wall of the placement box 3 close to the connecting strip 402, and the extending direction of the channel 304 is the same as the length direction of the connecting strip 402. When the placement box 3 is placed in the placement space, the channels 304 of two adjacent placement boxes 3 can be attached to the surface of the corresponding connecting strip 402, and two adjacent surfaces of the adjacent placement boxes 3 can also be attached.

[0029] Embodiment 5

[0030] This embodiment is an improved solution based on Embodiment 1. Its main structure is the same as that of Embodiment 1. The improvement lies in that as Figure 3 shown, in order to ensure the stable falling position of the cylindrical capacitor 2 entering the inside of the guiding cylinder 102, two opposite arc-shaped protrusions 104 are provided on the inner wall of the guiding cylinder 102 near its outlet. The minimum distance between the two arc-shaped protrusions 104 is greater than the diameter of the cylindrical capacitor 2, but not too large, otherwise the meaning of setting the arc-shaped protrusions 104 will be lost. In order to ensure that the cylindrical capacitor 2 can smoothly enter the guiding cylinder 102, an inwardly concave arc-shaped area 105 is provided on the inner wall of the guiding cylinder 102 near the trimming track 101, and the arc-shaped area 105 is close to the inlet end of the guiding cylinder 102. When the cylindrical capacitor 2 topples over, if it fails to fall on the side wall of the inlet end of the guiding cylinder 102, it will fall into the guiding cylinder 102 horizontally. Therefore, the distance between the inner wall of the guiding cylinder 102 far from the trimming track 101 and the trimming track 101 is less than the height of the cylindrical capacitor 2, but not too small, to ensure that the cylindrical capacitor 2 can vertically fall into the guiding cylinder 102.

[0031] Embodiment 6

[0032] This embodiment is an improved solution based on Embodiment 1. Its main structure is the same as that of Embodiment 1. The improvement lies in that as Figure 3 shown, a mounting plate 106 is installed at the inlet end of the guiding cylinder 102, and the mounting plate 106 is connected to the trimming track 101 by bolts.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
