With the rapid development of the electronics industry, the production efficiency and cutting accuracy requirements for circular capacitor bars are increasing.

[0003] Traditional cutting devices often have many shortcomings. For example, in terms of fixing the capacitor bars, their clamping structure is usually relatively simple and difficult to adapt to capacitor bars of different diameters, which causes the capacitor bars to shake easily during the cutting process, affecting the cutting accuracy and thus reducing the product qualification rate. Moreover, traditional devices lack effective collaborative design in the transportation and cutting operations of the capacitor bars, the transportation speed is unstable, and the cutting process is not smooth enough, resulting in low cutting efficiency. In addition, for switching between capacitor bars of different specifications, traditional equipment requires cumbersome manual adjustments, which is time-consuming and labor-intensive, and can hardly meet the needs of rapid switching of production tasks in modern large-scale production.

[0004] To this end, the present invention proposes a circular capacitor bar cutting device and a cutting method, which adopts a mobile roller with an adjustable crossing angle to be arranged in a placement component and controlled by a pneumatic rod 1 to adapt to the placement of capacitor bars with different diameters; the fixing component utilizes a plurality of pneumatic rods 2 in a specific arrangement, and combines a ventilation roller and a variable air pipe to achieve precise fixation according to the diameter of the capacitor bar, thereby ensuring the stability of the center position of the circle during cutting; the cooperation of the bidirectional threaded rod and the motor in the conveying component ensures the stable conveying of the capacitor bar and the precise control of the conveying length; the cutting component adopts a specially designed saber saw and related drive structure to achieve efficient and stable cutting, thereby improving the cutting accuracy, cutting efficiency and adaptability to capacitor bars of different specifications, and effectively solving the problems existing in the traditional cutting device.

[0044] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various forms, so the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not connected with the invention will be omitted from the drawings.

[0045] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0046] Example:

[0047] Please refer to Figure 1 and Fig.11 As shown, this embodiment introduces a specific structure of a circular capacitor strip cutting device, comprising a support (1), a placement component is installed on the top of the support (1), a frame 2 (6) is fixedly connected to the top of the support (1), and a fixing component, a conveying component, and a cutting component are installed inside the frame 2 (6);

[0048] The placement component is used to place the capacitor bar, and the placement component includes a frame (2) fixedly connected to the top of the support (1), a plurality of groups of movable rollers (4) adjacent to each other are arranged in the middle of the frame (2), the movable rollers (4) adjacent to each other are arranged crosswise, both sides of the plurality of movable rollers (4) are fixedly connected with universal joints (3), the end of the universal joint (3) adjacent to the movable roller (4) away from the movable roller (4) is fixedly connected to the middle of the frame (2), the internal rotation of the frame (2) is connected with a plurality of pneumatic rods (5), the output ends of the plurality of pneumatic rods (5) are all opposite to the universal joint (3) at the end of the movable roller (4) away from the movable roller ( 4), one end of each of the two adjacent moving rollers (4) is rotatably connected, and the crossing angle of each of the two adjacent moving rollers (4) changes with the diameter of the capacitor bar. The pneumatic rod (5) pushes the opposite ends of the adjacent moving rollers (4) to move, thereby realizing the change of the crossing angle of the adjacent moving rollers (4). The two ends of the moving rollers (4) are fixedly connected with universal joints (3), thereby realizing the arbitrary change of the angle of the moving rollers (4). When the pneumatic rod (5) is fully retracted, each group of crossed moving rollers (4) presents the maximum angle, and the corresponding capacitor bar diameter is the largest. As the pneumatic rod (5) continues to extend, the angle of each group of crossed moving rollers (4) gradually decreases, and the corresponding capacitor bar diameter gradually decreases.

[0049] The fixed assembly comprises a delivery port (7) fixedly connected to the middle of the frame (6), and a plurality of pneumatic rods (8) are installed on the outer side of the delivery port (7). The plurality of pneumatic rods (8) are arranged in a ring in groups of two on the outer side of the delivery port (7), with a total of ten groups, with the bottom group being X1, and the subsequent ten groups of pneumatic rods (8) being X1, X2, X3, X4, X5, X6, X7, X8, X9, and X10, respectively. The extension of each group of pneumatic rods (8) varies with the diameter of the capacitor strip. The diameter of the capacitor bar is divided into multiple levels, such as: 0cm-5cm, 5cm-10cm, 10cm-15cm, 15cm or more to the maximum diameter adapted by the device. When the diameter of the capacitor bar is 0cm-5cm, only X2, X6, and X10 of the multiple sets of pneumatic rods (8) will extend to clamp the capacitor bar. When the diameter of the capacitor bar is 5cm-10cm, only X2, X4, X8, and X10 of the multiple sets of pneumatic rods (8) will extend to clamp the capacitor bar. When the diameter of the capacitor bar is 10cm-15cm, only X2, X4, X6, X8, and X10 of the plurality of pneumatic rods 2 (8) will extend to clamp the capacitor bar. When the diameter of the capacitor bar is more than 15cm, the plurality of pneumatic rods 2 (8) will extend to clamp the capacitor bar. The clamps of different diameters can fix the capacitor bar at the center position, ensuring that the center of the capacitor bar of different diameters is always kept at the center of the plurality of pneumatic rods 2 (8) during cutting. Since the output end of each pneumatic rod 2 (8) is provided with The rubber roller is provided to facilitate the movement of the capacitor strip. However, since the rubber roller itself has thickness, when the diameter of the capacitor strip is small, if multiple sets of pneumatic rods (8) are used to clamp the capacitor strip at the same time, the diameter formed by the thickness of the multiple sets of rubber rollers may be larger than the diameter of the capacitor strip, and the capacitor strip cannot be tightly fixed, resulting in shaking during cutting. Therefore, by changing the number of pneumatic rods (8) clamping the capacitor strip, the diameter formed by the rubber rollers can be adapted to the diameter of the capacitor strip, so as to achieve perfect fixation.

[0050] An equipment box (9) is arranged inside the frame 2 (6), and two air change pipes (10) arranged on the left and right are fixedly connected inside the equipment box (9), and the top ends of the two air change pipes (10) are fixedly connected to a plurality of connecting pipes (11), and the plurality of connecting pipes (11) are each provided with two output ends, and the output ends of the plurality of connecting pipes (11) are each fixedly connected to an air supply pipe 1 (12), and the ends of the plurality of air supply pipes 1 (12) away from the connecting pipe (11) are each connected to the air inlet end of the pneumatic rod 2 (8), and two air exchange rollers (13) are installed inside the two air change pipes (10), and the outsides of the two air exchange rollers (13) are each provided with four groups of air ports (1 4), respectively Y1, Y2, Y3, Y4, each group of air ports (14) corresponds to the diameter of the capacitor strips at different levels, Y1 corresponds to the maximum diameter of 15 cm or more to the device, that is, corresponds to each group of pneumatic rods (8), Y2 corresponds to the capacitor strips of 10 cm-15 cm, that is, corresponds to the five groups of pneumatic rods (8) of X2, X4, X6, X8, and X10, Y3 corresponds to the capacitor strips of 5 cm-10 cm, that is, corresponds to the four groups of pneumatic rods (8) of X2, X4, X8, and X10, Y4 corresponds to the capacitor strips of 0 cm-5 cm, that is, corresponds to the three groups of pneumatic rods (8) of X2, X6, and X10, one end of the two air exchange rollers (13) is connected to the control unit through the air pipe (15) The device box (9) is connected to a valve (16), the input end of the control valve (16) is connected to the output end of the air pump (17), the interior of the device box (9) is fixedly connected with a motor 1 (18), the other end of the two ventilation rollers (13) is connected to the output end of the motor 1 (18) through a chain group 1 (19), when it is necessary to adjust the extension of the multiple groups of pneumatic rods 2 (8) according to the diameter of the capacitor bar, the motor 1 (18) is started first, and the motor 1 (18) drives the two ventilation rollers (13) to rotate respectively through the two chain groups 1 (19), and then adjusts the positions of Y1, Y2, Y3, and Y4, and when the air port (14) is rotated to the top, the air port (14) is connected to the air port (14) through the connecting pipe (11). The gas pipe (12) is connected to each other, and then the gas is transported from the gas pipe (15) to the inside of the gas exchange roller (13) through the air pump (17), and then transported to the inside of the gas pipe (12) through the air port (14), and then transported to the inside of the pneumatic rod (8) to control the extension and retraction of the pneumatic rod (8). The control valve (16) is used to control the gas of the air pump (17) to enter the inside of the left gas exchange roller (13) or the inside of the right gas exchange roller (13). When a certain group of gas ports (14) on each gas exchange roller (13) is transporting gas, the other three groups of gas ports (14) will be closed by the inside of the gas pipe (10) outside the gas exchange roller (13), thereby preventing gas leakage;

[0051] The conveying assembly comprises two bidirectional threaded rods (20) rotatably connected to the inside of the second frame (6), the outsides of the two bidirectional threaded rods (20) are rotatably connected to two moving blocks (21), one side of the moving block (21) is installed with a motor (23), the output ends of the two motors (23) are fixedly connected to rubber rollers (22), the two rubber rollers (22) are rotatably connected to the outside of the moving block (21) on the other side when they move away from the motor (23), a chain set (26) is installed between the two bidirectional threaded rods (20), the bottom end of the right bidirectional threaded rod (20) is fixedly connected to a gear (25), the inside of the second frame (6) is installed with a motor (24), the output end of the gear (25) is meshed with the gear (25) through teeth, and the motor (24) is used to rotate the output end of the gear (25). ) drives the gear 1 (25) to rotate and then drives the right bidirectional threaded rod (20) to rotate. Since a chain set 2 (26) is installed between the two bidirectional threaded rods (20), the right bidirectional threaded rod (20) will drive the left bidirectional threaded rod (20) to rotate simultaneously through the chain set 2 (26). The simultaneous rotation of the bidirectional threaded rods (20) on both sides will drive the upper and lower adjacent moving blocks 1 (21) to move to opposite ends or opposite ends at the same time, and then drive the two rubber rollers (22) to move relative to or opposite to each other. The two rubber rollers (22) are driven by the motor 2 (23) to rotate. The relative movement of the rubber rollers (22) will clamp the capacitor bar. The upper and lower distances of the rubber rollers (22) can be adjusted to accommodate capacitor bars of different diameters. The rubber rollers (22) are driven by the motor 2 (23) to rotate and then the capacitor bar is transported to the front side;

[0052] The cutting assembly comprises four sliding rods (27) fixed inside two frames (6), the four sliding rods (27) are arranged in groups of two on both sides of the conveying port (7), and moving blocks (28) are slidably connected between the sliding rods (27) on both sides. Two one-way threaded rods (29) are rotatably connected inside the frame (6), and the two one-way threaded rods (29) are respectively threadedly connected to two adjacent moving blocks (28). The lower side of the one-way threaded rod (29) on the left side is fixedly connected with a gear (31). A motor (4) (30) is installed inside the frame (6), and the output end of the motor (30) is meshed with the gear (31) through teeth. A chain group (32) is installed between the two one-way threaded rods (29), and a saber saw (31) is installed between the two moving blocks (28). 33), the saw blade of the saber saw (33) is designed with saw teeth on both sides. When cutting is required, the motor 4 (30) is started to drive the gear 2 (31) to rotate and then drive the left one-way threaded rod (29) to rotate. The left one-way threaded rod (29) drives the right one-way threaded rod (29) to rotate at the same time through the chain group 3 (32). The two moving blocks 2 (28) are limited by the slide bar (27) to prevent them from rotating. Then, when the one-way threaded rods (29) on both sides rotate, they will drive the moving blocks 2 (28) on both sides to move up and down at the same time, and then drive the saber saw (33) to move up and down, so that the capacitor strip is cut by the saber saw (33). Since the saw blade of the saber saw (33) is designed with saw teeth on both sides, the saber saw (33) can cut the capacitor strip when it moves up and down, avoiding the waste of time caused by the back and forth movement of the saber saw (33);

[0053] like Fig.12 As shown above, in summary, a cutting method for a circular capacitor bar cutting device applied to the above circular capacitor bar cutting device comprises the following steps:

[0054] Step 1, equipment adjustment, determining the diameter of the capacitor bar, adjusting the cross angle between adjacent moving rollers (4) according to the diameter of the capacitor bar, and determining the air port (14) intersecting the connecting tube (11) to determine each pneumatic rod (8) clamping the capacitor bar;

[0055] Specifically: the diameter of the capacitor bar is 12 cm, and a plurality of pneumatic rods (5) are first started to adjust the crossing angle of adjacent moving rollers (4) by pushing the moving rollers (4) to rotate. As the crossing angle decreases, the capacitor bar is continuously lifted and moved upward, so that the capacitor bar is placed at the center of the conveying port (7) through the moving rollers (4). According to the diameter of the capacitor bar, the pneumatic rods (8) used to clamp the capacitor bar are X2, X4, X6, X8, and X10, and then the motor (18) is started. The motor (18) drives the two ventilation rollers (13) to rotate through the chain group (19), and then rotates a group of air ports (14) corresponding to the same to the top of the ventilation roller (13) so that the air ports are connected to the connecting pipe (11);

[0056] Step 2: Fix the capacitor bar, push the capacitor bar placed on the top of the placement component to the middle of the conveying component, fix the capacitor bar by the fixing component to prevent the capacitor bar from shaking during cutting, and then push the capacitor bar to move toward the cutting component by the conveying component;

[0057] Specifically: when one end of the capacitor strip is placed on the rear side of the cutting assembly, the control valve (16) starts the gas delivered by the control air pump (17) to enter the inside of the right gas change tube (10) from the gas delivery pipe 2 (15), and the gas inside the right gas change tube (10) passes through the gas port (14) at the top of the right gas exchange roller (13), namely Y2, and the gas is delivered to the inside of the pneumatic rods 2 (8) of X2, X4, X6, X8, and X10 through the connecting pipe (11) and the gas delivery pipe 1 (12). After the other gas enters, it will push the pneumatic rod 2 (8) to extend and then clamp the capacitor strip. The excess gas inside the pneumatic rod 2 (8) is discharged from the left gas delivery pipe 1 (12) through the right gas exchange roller (13) and the control valve (16);

[0058] Step 3: conveying the capacitor bar. After the fixing component fixes the capacitor bar, the capacitor bar is continuously conveyed to the cutting component through the conveying component.

[0059] Specifically: start the motor three (24), the motor three (24) drives the gear one (25) to rotate and then drives the right bidirectional threaded rod (20) to rotate. Since the chain set two (26) is installed between the two bidirectional threaded rods (20), when the right bidirectional threaded rod (20) rotates, it will drive the left bidirectional threaded rod (20) to rotate at the same time through the chain set two (26). The simultaneous rotation of the bidirectional threaded rods (20) on both sides will drive the upper and lower adjacent moving blocks one (21) to move to the opposite end or the opposite end at the same time, and then The two rubber rollers (22) are driven to move relative to or away from each other. The capacitor strip is clamped by the relative movement of the rubber rollers (22). The two rubber rollers (22) are driven by the second motor (23) to rotate, thereby transporting the capacitor strip to the cutting assembly. The number of rotations of the rubber rollers (22) is related to the cutting length of the capacitor strip. As the number of rotations of the rubber rollers (22) changes, the cutting length of the capacitor strip changes. The number of rotations of the rubber rollers (22) is determined by the required cutting length of the capacitor strip.

[0060] Step 4: cutting the capacitor bar, transporting the capacitor bar to the cutting assembly through the conveying assembly, and then cutting the capacitor bar through the cutting assembly;

[0061] Specifically: according to the required length, the capacitor bar is transported to the corresponding position through the transport assembly, and then the saber saw (33) is started, and then the motor four (30) is started. The motor four (30) drives the gear two (31) to rotate and then drives the left one-way threaded rod (29) to rotate. The left one-way threaded rod (29) drives the right one-way threaded rod (29) to rotate at the same time through the chain group three (32). Then, the one-way threaded rods (29) on both sides will drive the moving blocks (28) on both sides to move up and down at the same time when rotating, and then drive the saber saw (33) to move up and down. When the saber saw (33) moves downward, it cuts the capacitor bar. After the cutting is completed, the motor four (30) is paused, and then the transport assembly transports the capacitor bar to the corresponding position again. At this time, the motor four (30) is started again and then drives the saber saw (33) to move upward. Since the saw blade of the saber saw (33) is designed with saw teeth on both sides, the saber saw (33) can also perform cutting work when it moves upward.

[0062] Step 5, replacing the capacitor strips. After a group of capacitor strips are cut, the control valve (16) is controlled to adjust the replacement of the air intake and exhaust on the left and right sides to adjust the contraction of the pneumatic rod 2 (8) and then fix the new capacitor strips.

[0063] Specifically: first, the control valve (16) is started to change the direction of the gas through the control valve (16), and the gas delivered by the air pump (17) is delivered from the support (1) to the inside of the right air change pipe (10), and then from the right air port (14) through the air delivery pipe 1 (12) into the inside of the pneumatic rod 2 (8), and the gas enters the side of the pneumatic rod 2 (8) close to the output end, and then pushes the pneumatic rod 2 (8) to contract, thereby releasing the pneumatic rod 2 (8) from fixing the capacitor bar, and at this time, the new capacitor bar enters the middle part of the delivery port (7) again, and then the control valve (16) is adjusted again to make the gas of the air pump (17) enter the inside of the left air change pipe (10) again, and enter the inside of the pneumatic rod 2 (8) through the air port (14) inside the air change pipe (10), and push the pneumatic rod 2 (8) to extend again to fix the capacitor bar, and so on;

[0064] Step 6, fixing capacitor bars of different diameters, by determining the diameter of the capacitor bars, starting the motor 1 (18) to drive the chain set 1 (19) and then drive the two air exchange rollers (13) to rotate to adjust the positions of the different Y1, Y2, Y3, and Y4 air ports (14);

[0065] Specifically, if the new capacitor bar diameter is 3 cm, the motor 1 (18) drives the chain group 1 (19) and then drives the two ventilation rollers (13) to rotate the air port (14) of the Y4 group to the top of the ventilation roller (13), so that it is connected with the connecting pipe (11), and then the air port (14) of the Y4 group is connected with the three groups of pneumatic rods 2 (8) of X2, X6, and X10 through the connecting pipe (11) and the air supply pipe 1 (12), and then the gas only pushes the three groups of pneumatic rods 2 (8) of X2, X6, and X10 to extend or contract to correspond to the new capacitor bar diameter.

[0066] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
