[0031] Embodiment

[0032] Please refer to Figures 1 to 5 , this embodiment provides a capacitor pin shearing device 100, which includes a shearing assembly 10, a bending assembly 20, and a fixing assembly 30. The shearing assembly 10 includes a stationary knife 11 and a moving knife 12 arranged oppositely. The bending assembly 20 includes a pre-pressing block 21 and a bending member 22. The fixing assembly 30 includes a pressing block 31. The stationary knife 11 has a first acting surface and a second acting surface arranged adjacent to each other. The pre-pressing block 21 is used to cooperate with the first acting surface to press the pin 220 of the capacitor 200 to be sheared. The bending member 22 moves towards the stationary knife 11 to cooperate with the second acting surface to bend the pin 220 of the capacitor 200 to be sheared. The pressing block 31 moves towards the stationary knife 11 to cooperate with the second acting surface to press the capacitor 200 to be sheared. The moving knife 12 moves towards the stationary knife 11 to shear the pin 220 of the capacitor 200 to be sheared. The capacitor pin shearing device 100 has the advantages of reasonable design and simple structure, and can effectively improve the shearing quality and efficiency of the capacitor.

[0033] It should be noted that, first, generally, the capacitor 200 to be sheared includes a body 210, a pin 220, and a tape connected in sequence. In order to meet the usage requirements of different electrical appliances, during the capacitor shaping process, it is necessary to shear the tape and part of the pin 220 near the tape, while retaining the body 210 and part of the pin 220 near the body 210. For this purpose, the capacitor pin shearing device 100 processes the pin 220 of the capacitor 200 to be sheared through two actions of bending and shearing. Taking the position between the part of the pin 220 to be sheared and the part of the pin 220 to be retained as the inflection point of bending for bending treatment, and then taking this position as the break point of shearing for shearing treatment, so as to realize the shearing of the pin 220 of the capacitor 200 to be sheared.

[0034] Specifically, as Figure 1 , Figure 4 and Figure 5As shown, after the pre-pressing block 21 cooperates with the first acting surface to tightly press the part of the pins 220 to be sheared, the bending member 22 cooperates with the second acting surface to bend the pins 220 of the capacitor 200 to be sheared. At this time, the point on the pins 220 of the capacitor 200 to be sheared located at the connection of the first acting surface and the second acting surface is the inflection point of the bending. After the pressing block 31 cooperates with the second acting surface to tightly press the part of the pins 220 to be retained, the moving blade 12 cooperates with the stationary blade 11 to shear the pins 220 of the capacitor 200 to be sheared. At this time, the point on the pins 220 of the capacitor 200 to be sheared located at the connection of the first acting surface and the second acting surface is the breaking point of the shearing.

[0035] As Figure 5 shown, since in the above process, the capacitor 200 to be sheared only rotates around the connection of the first acting surface and the second acting surface without displacement in other directions, the inflection point of the bending and the breaking point of the shearing are the same point on the pins 220 of the capacitor 200 to be sheared. Regarding the specific selection of this position, that is, regarding the specific selection of the length of the part of the pins 220 to be sheared, those skilled in the art should be able to make reasonable designs and selections according to actual requirements, and no specific limitations are imposed here.

[0036] Second, after the pre-pressing block 21 cooperates with the first acting surface to tightly press the part of the pins 220 to be sheared, the bending member 22 then cooperates with the second acting surface to bend the pins 220 of the capacitor 200 to be sheared. In this way, the clamping force provided by the pre-pressing block 21 and the first acting surface can keep the relative position of the pins 220 fixed during the bending process, avoiding phenomena such as shaking or even offset. After the pressing block 31 cooperates with the second acting surface to tightly press the part of the pins 220 to be retained, the moving blade 12 then cooperates with the stationary blade 11 to shear the pins 220 of the capacitor 200 to be sheared. In this way, the clamping force provided by the pressing block 31 and the second acting surface can keep the relative position of the pins 220 fixed during the shearing process, avoiding phenomena such as shaking or even offset. It is precisely because of the fixed relative position of the pins 220 during the bending process and the shearing process that the cut feet can be kept flat and the shearing quality is improved.

[0037] Since the first acting surface and the second acting surface of the stationary blade 11 are arranged adjacent to each other, there is an included angle between the first acting surface and the second acting surface. For example, the angle of the included angle can be 70°, 80°, 90°, 100°, 110°, etc. No limitation is imposed on the angle of the included angle here, and those skilled in the art should be able to make reasonable designs and selections according to actual requirements. Exemplarily, when the included angle is 90°, when the moving blade 12 cooperates with the stationary blade 11 to shear the pins 220, the extending direction of the cut surface formed on the pins 220 can be perpendicular to the extending direction of the pins 220, so that the cut feet can always be kept flat and the shearing quality is further improved.

[0038] As described above, the capacitor pin shearing device 100 includes a shearing assembly 10, a bending assembly 20, and a fixing assembly 30. The shearing assembly 10 includes a stationary blade 11 and a moving blade 12 which are oppositely arranged. The bending assembly 20 includes a pre-pressing block 21 and a bending member 22. The fixing assembly 30 includes a pressing block 31. The stationary blade 11 has a first acting surface and a second acting surface which are adjacently arranged. The pre-pressing block 21 is used to cooperate with the first acting surface to tightly press the pins 220 of the capacitor 200 to be sheared. The bending member 22 moves towards the stationary blade 11 to cooperate with the second acting surface to bend the pins 220 of the capacitor 200 to be sheared. The pressing block 31 moves towards the stationary blade 11 to cooperate with the second acting surface to tightly press the capacitor 200 to be sheared. The moving blade 12 moves towards the stationary blade 11 to shear the pins 220 of the capacitor 200 to be sheared. After the pre-pressing block 21 cooperates with the first acting surface to tightly press a part of the pins 220 to be sheared, the bending member 22 then cooperates with the second acting surface to bend the pins 220 of the capacitor 200 to be sheared. In this way, the clamping force provided by the pre-pressing block 21 and the first acting surface can keep the relative position of the pins 220 fixed during the bending process, avoiding phenomena such as shaking or even offset. After the pressing block 31 cooperates with the second acting surface to tightly press the part of the pins 220 to be retained, the moving blade 12 then cooperates with the stationary blade 11 to shear the pins 220 of the capacitor 200 to be sheared. In this way, the clamping force provided by the pressing block 31 and the second acting surface can keep the relative position of the pins 220 fixed during the shearing process, avoiding phenomena such as shaking or even offset. It is precisely because of the fixed relative position of the pins 220 during the bending process and the shearing process that the cut pins can be kept flat and the shearing quality is improved. Compared with manual shearing in the prior art, the capacitor pin shearing device 100 can also effectively improve the shearing efficiency.

[0039] As Figure 2 and Figure 3 shown, in this embodiment, the bending assembly 20 further includes a first mounting seat 23. A first sliding groove is provided on the first mounting seat 23. The pre-pressing block 21 is accommodated in the first sliding groove. A first spring 231 is provided between one end of the pre-pressing block 21 away from the stationary blade 11 and the inner wall surface of the first sliding groove.

[0040] It should be noted that a first sliding groove is provided on the first mounting seat 23, and the preloading block 21 is accommodated in the first sliding groove, so that the preloading block 21 can move relative to the first mounting seat 23 along the extending direction of the first sliding groove. A first spring 231 is provided between the end of the preloading block 21 away from the stationary blade 11 and the inner wall surface of the first sliding groove, so that when the end of the preloading block 21 away from the first mounting seat 23 is not subjected to the abutting action of the first acting surface, the first spring 231 is in a tensioned state, and when the end of the preloading block 21 away from the first mounting seat 23 is subjected to the abutting action of the first acting surface, the first spring 231 is in a compressed state, which can play a role in protecting the pin 220 from being damaged.

[0041] As Figure 2 and Figure 3 shown, in this embodiment, two relatively arranged mounting holes are further provided on the first mounting seat 23, a connecting hole is provided on the bending member 22, and a connecting shaft passes through the mounting hole and the connecting hole, so that the bending member 22 is rotatably connected to the first mounting seat 23. The bending member 22 is located above the second acting surface, and a second spring 232 is provided between the end of the bending member 22 away from the stationary blade 11 and the first mounting seat 23.

[0042] It should be noted that, first, two relatively arranged mounting holes are further provided on the first mounting seat 23, a connecting hole is provided on the bending member 22, and a connecting shaft passes through the mounting hole and the connecting hole, so that the bending member 22 is rotatably connected to the first mounting seat 23. Therefore, when the bending member 22 cooperates with the second acting surface to bend the pin 220 of the capacitor 200 to be sheared, the end of the bending member 22 away from the first mounting seat 23 is subjected to the abutting action of the second acting surface, and the second spring 232 can be in a compressed state with the connecting shaft as the rotation axis, thereby playing a role in protecting the pin 220 from being damaged.

[0043] Second, since the bending member 22 and the preloading block 21 are respectively arranged on the first mounting seat 23, the first mounting seat 23 can drive the bending member 22 and the preloading block 21 to move with the same movement trend. Also, because the first acting surface can abut against the preloading block 21, and the bending member 22 is located above the second acting surface, when the first mounting seat 23 moves towards the direction close to the stationary blade 11, the preloading block 21 moves with the same movement trend until the preloading block 21 abuts against the first acting surface, and the bending member 22 can continue to move with the same movement trend until it cooperates with the second acting surface to bend the pin 220 of the capacitor 200 to be sheared.

[0044] As Figure 2 and Figure 3As shown, in this embodiment, the bending member 22 includes a bending member body 221 and a rolling member 222 that are rotatably connected, the bending member body 221 is a Y-shaped structure, and the rolling member 222 is arranged between two extension arms of the Y-shaped structure. Of course, in other embodiments, the bending member 22 can also be a rectangular block or other structure, that is, the pin 220 is bent by pushing horizontally. Compared with the form of pushing horizontally, the rolling form provided in this embodiment can avoid damaging the part of the pin 220 that needs to be retained during the bending process as much as possible.

[0045] like Figure 1 and Figure 4 As shown, in this embodiment, the fixing assembly 30 further includes a second mounting seat 32, a second slide groove is provided on the second mounting seat 32, a clamping block 31 is accommodated in the second slide groove, and a third spring 321 is provided between an end of the clamping block 31 away from the stationary knife 11 and the inner wall surface of the second slide groove. In this embodiment, the movable knife 12 is fixedly connected to the second mounting seat 32, and the movable knife 12 and the clamping block 31 are arranged adjacent to each other.

[0046] It should be noted that, first, similar to the pre-pressing block 21, the first mounting seat 23 and the first spring 231, a second slide groove is provided on the second mounting seat 32, and the pressing block 31 is accommodated in the second slide groove, so that the pressing block 31 can move relative to the second mounting seat 32 along the extension direction of the second slide groove. A third spring 321 is provided between the end of the pressing block 31 away from the static knife 11 and the inner wall surface of the second slide groove, so that when the end of the pressing block 31 away from the second mounting seat 32 is not supported by the second action surface, the third spring 321 is in a tensioned state, and when the end of the pressing block 31 away from the second mounting seat 32 is supported by the second action surface, the third spring 321 is in a compressed state, which can protect the pin 220 from being damaged.

[0047] Second, since the movable knife 12 and the clamping block 31 are respectively arranged on the second mounting seat 32, the second mounting seat 32 can drive the movable knife 12 and the clamping block 31 to move with the same movement trend. Because the second acting surface can resist the clamping block 31, and the movable knife 12 is located above the first acting surface, when the second mounting seat 32 moves toward the direction close to the stationary knife 11, the clamping block 31 moves with the same movement trend until the clamping block 31 resists against the second acting surface, and the movable knife 12 can continue to move with the same movement trend until it cooperates with the first acting surface to shear the pin 220 of the capacitor 200 to be sheared.

[0048] like Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the stationary blade 11 further has a third working surface disposed opposite to the first working surface. The fixing assembly 30 further includes a limiting groove 33 located on the side of the third working surface away from the first working surface for accommodating the capacitor 200 to be sheared after bending. Wherein, the shape of the limiting groove 33 should match the shape of the capacitor 200 to be sheared.

[0049] As Figure 1 , Figure 4 and Figure 5 shown, in this embodiment, the fixing assembly 30 further includes a lifting mechanism 34 fixedly connected to the limiting groove 33 for raising or lowering the limiting groove 33. Exemplarily, the lifting mechanism 34 can be a pneumatic cylinder to facilitate flexible adjustment of the height of the limiting groove 33, thereby changing the horizontal height of the capacitor 200 to be sheared to ensure that the remaining part of the lead 220 is in contact with the second working surface.

[0050] Furthermore, as Figure 1 , Figure 4 and Figure 5 shown, in this embodiment, the fixing assembly 30 further includes a limiting block 35 located on the side of the limiting groove 33 away from the third working surface. The limiting block 35 moves towards the stationary blade 11 to cooperate with the third working surface to limit the capacitor 200 to be sheared, so as to prevent the capacitor 200 to be sheared from shaking or even shifting during the shearing process of the lead 220.

[0051] It should be noted that all the above components capable of relative movement, including the moving blade 12, the first mounting seat 23, the second mounting seat 32, and the limiting block 35, can be driven by a driving member. Exemplarily, the driving member can be a pneumatic cylinder or a hydraulic cylinder. Compared with the hydraulic cylinder, the pneumatic cylinder can already meet the requirements of the capacitor lead shearing device 100, and has a simpler structure and lower cost.

[0052] Further, in order to save the floor area of the capacitor pin shearing device 100, a first air cylinder, a transmission member, and a second air cylinder are sequentially connected in a driving manner at one end of the first mounting seat 23 away from the preloading block 21. Among them, the first air cylinder and the second air cylinder are parallel to each other and have opposite directions. When the telescopic rod of the second air cylinder retracts, the second air cylinder can be driven by the transmission member to move toward the side close to the stationary knife 11. At this time, if the telescopic rod of the first air cylinder extends, the preloading block 21 and the bending member 22 can be driven by the first mounting seat 23 to continue moving toward the side close to the stationary knife 11; when the telescopic rod of the first air cylinder retracts, the preloading block 21 and the bending member 22 can be driven by the first mounting seat 23 to move away from the side of the stationary knife 11. At this time, if the telescopic shaft of the second air cylinder extends, the first air cylinder can be driven by the transmission member to continue moving away from the side of the stationary knife 11. Similarly, the driving of other components can also be achieved by two air cylinders that are parallel to each other and have opposite directions, which will not be elaborated here.

[0053] The present application also provides a capacitor processing device. The capacitor processing device provided in this embodiment includes the above-mentioned capacitor pin shearing device 100. Since the structure and beneficial effects of the capacitor pin shearing device 100 have been described in detail in the foregoing embodiments, they will not be elaborated here.

[0054] The foregoing are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
