Description

Technical Field

[0001] The present invention relates to the field of automation equipment, and in particular to an automatic fuse cutting device and a cutting process thereof, and a fuse cutting machine. Background Art

[0002] A fuse is an electrical device that generates heat to melt its fuse element, disconnecting the circuit when the current exceeds a specified value. A fuse is a current protector that uses the principle that, after the current exceeds a specified value for a period of time, the heat generated by the fuse element melts, thereby disconnecting the circuit. Fuses are widely used in high and low voltage power distribution and control systems, as well as in electrical equipment. As a short-circuit and overcurrent protector, they are one of the most commonly used protective devices.

[0003] The fuse structure includes a main ceramic shell, a fuse inserted in the ceramic shell, and terminals connected to both ends of the ceramic shell, wherein the ceramic shell is a rectangular body structure with mutually penetrating cavities inside, and the fuse is a bow-shaped sheet structure, which is inserted in the cavity of the rectangular ceramic shell, and the ends of the fuse extend from both ends of the ceramic shell and are vertically bent and attached to the end face of the ceramic shell, and then bent horizontally, and finally the terminals assembled on the outside of the ceramic shell are connected and fixed. During the assembly of the fuse, it is first necessary to insert the fuse into the ceramic shell and attach it to the inner wall of the cavity of the ceramic shell, and after the bent part of the fuse is attached to the end face of the ceramic shell, the external terminal is pressed onto the fuse, and the terminal is fixed to the ceramic shell by gluing and screwing to form an integral fuse structure. Since the horizontally bent part of the fuse end exceeds the end face of the terminal, it is necessary to cut the excess part of the fuse neatly along the end face of the terminal. Based on the above process requirements, it is necessary to design a fuse cutting device to automatically cut the excess part of the fuse after assembly. Since the fuse is a metal sheet structure, it is affected by its internal stress and is prone to curling, burrs, etc. during the cutting process. Therefore, it is necessary to design an automatic fuse cutting mechanism to solve the above technical problems. Summary of the Invention

By obliquely mounting the blade and pressing the blade, the blade surface line and the fuse cutting line are aligned with each other during cutting, thereby realizing cutting guidance, ensuring the accuracy of the cutting path while avoiding damage to the terminal during cutting. Moreover, by bending the cutter to reserve space for thickness variation, cutting errors caused by the cutter not being able to close to the fuse due to errors are avoided.

[0034] A fuse cutting machine includes an automatic fuse cutting device.

[0035] The beneficial effects of the present invention are:

[0036] In response to the defects and shortcomings of the existing technology, the present invention independently developed and designed a device for cutting fuses obliquely by obliquely mounting the fuse to achieve point-contact cutting between the cutter and the fuse surface, effectively reducing cutting stress and reducing curling, burrs, etc. during cutting. By obliquely mounting the blade and pressing the blade, the blade surface line and the fuse cutting line are aligned with each other during cutting, achieving cutting guidance, ensuring the accuracy of the cutting path while avoiding damage to the terminal during cutting. By bending the cutter to reserve thickness variation space, the invention avoids cutting errors caused by the cutter not being able to close to the fuse due to errors. The invention provides an automatic fuse cutting device, a cutting process, and a fuse cutting machine.

[0037] The present invention aims to design an automatic fuse cutting device, which is used to automatically cut fuses made of metal sheets. The device takes into account the problems of fuse curling and burrs caused by excessive cutting stress in existing technologies and fuse cutting experiments, the problem of the cutter damaging the terminal surface during the cutting process, and the problem of cutting accuracy caused by an assembly gap between the fuse and the blade due to equipment assembly errors (for example, after the cutter moves to the cutting position, due to assembly errors, the cutter does not fit the fuse as intended, or the blade line does not align with the fuse cutting line). The present invention adopts a blade as a cutting execution component, and the overall support structure is a vertical frame structure. The support is driven by a transverse cylinder arranged on the frame to move laterally linearly. The bottom plate and the top vertical plate of the support are respectively provided with a first slide rail and a second slide rail extending in the longitudinal direction; the longitudinal movement seats of the two sets of longitudinal movement components are respectively slidably embedded on the first slide rail at intervals, and are respectively driven by the longitudinal movement cylinder to move in the longitudinal direction; the longitudinal movement seat is provided with a vertical plate extending vertically upward on the side close to the bracket; the inner side wall of the vertical plate is provided with a third slide rail extending obliquely downward in the transverse direction, which serves as a guide and limiting structure of the cutting component during cutting. When cutting, the cutting component moves along the direction of the third slide rail, so that the cutter moves laterally and gradually cuts the fuse downward.

[0038] The cam is fixed on the upper part of the vertical support plate of the longitudinal movement seat, and the cam is fixed on the upper part of the vertical support plate of the longitudinal movement seat, so that the cam can move upward or downward in the longitudinal direction of the cutting blade, thereby improving the cutting quality.

[0039] In addition, the cutting assembly of the present invention adopts a vertical design. The cutting assembly is connected to the third slide rail through the cutting seat, and is connected to the output end of the cutting cylinder through a knife pressing guide seat arranged on the side wall of the cutting seat. The cutting cylinder drives the cutting seat to move along the direction of the third slide rail to realize fuse cutting; in particular, a knife pressing cylinder is also provided on the cutting seat. The function of the knife pressing cylinder is not only to drive the cutter to move downward to the cutting position, but also to press the cutter, that is, before cutting, when the cutter moves downward and touches the terminal surface, it continues to give the cutter a predetermined downward stroke, so that the cutter is in a partially bent state, thereby ensuring that the cutter surface is close to the terminal while having a certain thickness change space. When the thickness change space is greater than the assembly error, the cutting accuracy problem caused by the assembly error can be effectively avoided. However, if the cutter is set vertically in the existing manner, the pressing function cannot be achieved (a vertically set cutter will directly push against the fuse surface when it descends and cannot bend). Therefore, the premise of the pressing function is that the cutter is set at an angle. While setting the cutter at an angle, the front cutting blade line and the fuse cutting line can be aligned with each other, playing a guiding and limiting role during the cutting process, effectively ensuring the accuracy of the cutting position. In addition, this method allows the blade position of the cutter to contact the terminal surface, thereby effectively reducing the surface damage of the terminal or the damage to the cutter caused by the cutter during cutting. At the same time, the present invention uses a press guide seat as a guiding and limiting structure when the press is lowered. The press cylinder arranged at the top of the cutting seat drives the press slide slidably arranged in the guide groove of the press guide seat to move up and down, driving the inclined knife seat arranged at the bottom of the press slide to move up and down. The cutter is fixed by the inclined mounting surface of the clamping block arranged at the bottom side of the inclined knife seat. A limit frame is also provided on the side of the press knife guide seat. The outward-protruding limit block provided on the outer side wall of the press knife slide slides in the limit groove of the limit frame to limit the extreme position of the cutter during the lifting and lowering movement, thereby avoiding the press knife slide falling due to loose installation or excessive downward pressure causing deviation from the cutting position.

[0057] The transverse movement assembly is arranged on the machine base 1 and outputs power in the transverse direction;

[0058] The longitudinal movement components include two groups, which are connected to the output end of the transverse movement component and output power in the longitudinal direction;

[0059] The oblique drive assembly 9 includes two groups, and the two groups of oblique drive assemblies 9 are respectively arranged on the longitudinal movement assembly, and the output directions of the two groups of oblique drive assemblies 9 extend obliquely in the transverse direction and have an inclination angle with the horizontal plane. This inclination angle allows the blade 1110 of the cutting assembly 11 to contact the fuse point during cutting;

[0060] The cutting assembly 11 includes two groups, so as to synchronously cut the fuses at both ends of the fuse. The two groups of cutting assemblies 11 are respectively connected to the output ends of the oblique drive assembly 9, and move obliquely downward along the output direction of the oblique drive assembly 9 to cut the fuses.

[0061] The cutting assembly 11 includes a blade 1110 that is clamped obliquely. The blade 1110 is tilted at an angle to the vertical direction so that when the blade 1110 approaches the fuse downward, a cutting line a between the blade 1110 and the cutting edge 1111 is in contact and aligned with a fuse cutting line b.

[0062] The present invention designs an automatic fuse cutting device, a cutting process and a fuse cutting machine that realize point-contact cutting between a cutter and the surface of the fuse by obliquely mounting the fuse, effectively reducing cutting stress and reducing curling, burrs and the like during cutting. The oblique mounting of the blade and the pressing of the blade align the blade surface line with the fuse cutting line during cutting, thereby achieving cutting guidance, ensuring the accuracy of the cutting path while avoiding damage to the terminal during cutting. Furthermore, by bending the cutter to reserve space for thickness variation, cutting errors caused by the cutter not being able to closely contact the fuse due to errors are avoided. The present invention aims to design an automatic fuse cutting device, which is used to automatically cut fuses made of metal sheets. The device takes into account the problems of fuse curling and burrs caused by excessive cutting stress in existing technologies and fuse cutting experiments, the problem of the cutter damaging the terminal surface during the cutting process, and the problem of cutting accuracy caused by an assembly gap between the fuse and the blade due to equipment assembly errors (for example, after the cutter moves to the cutting position, due to assembly errors, the cutter does not fit the fuse as intended, or the blade line does not align with the fuse cutting line). The present invention adopts a blade 111 as a cutting execution component, and the overall support 4 of a vertical frame structure is used as a bearing structure. The support 4 is driven by a transverse cylinder 3 arranged on the frame 1 to move laterally linearly, and the bottom plate and the top vertical plate of the support 4 are respectively provided with a first slide rail 5 and a second slide rail extending in the longitudinal direction; the longitudinal movement seats 8 of the two sets of longitudinal movement components are respectively slidably embedded in the first slide rail 5 at intervals, and are respectively driven by the longitudinal movement cylinder 6 to move in the longitudinal direction; the longitudinal movement seat 8 is provided with a vertical plate extending vertically upward on the side close to the support 4; the inner side wall of the vertical plate is provided with a third slide rail 10 extending obliquely downward in the transverse direction, which serves as a guide and limiting structure for the cutting component 11 during cutting. When cutting, the cutting component 11 moves along the direction of the third slide rail 10, so that the cutter 1110 moves laterally while gradually cutting the fuse 02 downward.

[0063] like Figures 5 to 7 As shown in the figure, as an embodiment of the present invention, the fuse of the present invention includes a ceramic shell 01, a fuse 02 and a terminal 03, wherein the ceramic shell 01 is a rectangular box-shaped structure with a cavity extending through both ends thereof; the fuse 02 is a bow-shaped sheet structure, inserted into the cavity of the ceramic shell 01, with both ends extending to the outside of the ceramic shell 01 and successively bent in the vertical and horizontal directions; the terminal 03 includes two terminals 03, which are respectively arranged at both ends of the ceramic shell 01. The terminal 03 is an L-shaped plate structure, one side of which is in contact with the end face of the ceramic shell 01, and the vertical bent portion of the fuse 02 is pressed together and then fixedly connected to the end face of the ceramic shell 01 to form an integral fuse 0; the portion of the end of the fuse 02 bent in the horizontal direction extends to the outside of the terminal 03, forming a cutting portion 04.

[0064] The fuse cutting line b is a line connecting the outer end surface of the terminal 03 and the horizontally bent portion of the fuse 02 .

[0065] like Figures 1 to 3 As shown, as an embodiment of the present invention, the transverse movement assembly of the present invention includes a transverse movement cylinder 3 and a bracket 4, wherein the bracket 4 can be slidably embedded in the transverse movement slide rail 2 on the machine base 1, and the bracket 4 is a frame structure extending in the vertical direction. The bottom plate and the top vertical plate of the bracket 4 are respectively provided with a first slide rail 5 and a second slide rail in the longitudinal direction; the transverse movement cylinder 3 is horizontally arranged on the machine base 1, and the output section is connected to the bracket 4 so as to drive the bracket 4 to move horizontally and linearly.

[0066] like Figures 1 to 3 As shown, as an embodiment of the present invention, the longitudinal movement assembly of the present invention includes a longitudinal movement cylinder 6, a longitudinal movement connecting seat 7 and a longitudinal movement seat 8, wherein the longitudinal movement cylinder 6 is arranged on the bottom plate of the bracket 4 along the longitudinal direction; the longitudinal movement seat 8 is slidably embedded in the first slide rail 5, and is connected to the output end of the longitudinal movement cylinder 6 through the longitudinal movement connecting seat 7, and the longitudinal movement cylinder 6 drives the longitudinal movement seat 8 to move longitudinally in a straight line; the longitudinal movement seat 8 is provided with an upward extending vertical support plate close to the side of the bracket 4.

[0067] like Figures 8 to 10 As shown, as an embodiment of the present invention, the oblique mounting drive assembly 9 of the present invention includes an oblique cutting cylinder 91, an oblique mounting seat 92 and a connecting block 95, wherein,

[0068] The oblique mounting seat 92 is vertically connected to the side of the vertical support plate. A mounting groove 94 is formed on the upper portion of one side wall of the oblique mounting seat 92. A slide rail seat is fixed in the mounting groove 94.

[0071] The present invention is designed to provide an inclined cutting driving force by an inclined mounting drive assembly 9. The inclined mounting drive assembly 9 uses an inclined mounting seat 92 as a bearing structure. The inclined mounting seat 92 is connected to the side wall of the vertical support plate of the longitudinal displacement seat 8 to realize longitudinal movement. At the same time, a mounting groove 94 is provided on the upper part of one side wall of the inclined mounting seat 92. A slide rail seat is fixed in the mounting groove 94. The inclined mounting seat 92 is slidably embedded in the third slide rail through the slide rail seat. When the third slide rail is moved longitudinally, the position is limited. The inclined mounting surface 93 is provided at the lower part of the mounting groove 94 to install the inclined mounting seat 92. The cutting cylinder 91, after the end face of the cutting cylinder 91 is installed in contact with the oblique mounting surface 93, its output end maintains the same direction as the third slide rail 10, so that the cutting cylinder 91 drives the cutting assembly 11 to move obliquely downward or upward in the longitudinal direction along the direction of the third slide rail 10, so as to achieve point contact between the cutter 1110 and the fuse during cutting. Compared with line contact cutting, this point contact and oblique downward cutting method can effectively reduce cutting stress, reduce curling and burrs at the cutting part of the fuse during cutting, and improve cutting quality.

[0073] like Figures 1 to 3 , Figures 11 to 13 As shown, as an embodiment of the present invention, the cutting assembly 11 of the present invention further includes a cutting seat 111, a knife pressing cylinder 112, a knife pressing guide seat 113, a knife pressing slide seat 114 and a bevel knife seat 118, wherein,

[0074] The cutting seat 111 is an L-shaped structure, one side of the vertical plate is slidably embedded in the third slide rail 10, and the horizontal plate is connected to the upper part of the vertical plate and extends horizontally;

[0075] The knife pressing cylinder 112 is vertically arranged on the horizontal plate of the cutting seat 111, and the output end extends downward through the horizontal plate;

[0076] The knife pressing guide seat 113 is arranged below the knife pressing cylinder 112 and is connected to the other side wall of the vertical plate of the cutting seat 111. The knife pressing guide seat 113 is connected to the output end of the oblique drive assembly 9. A guide groove is provided in the knife pressing guide seat 113, which is through-through from top to bottom. The outer side of the guide groove is an open surface.

[0077] The knife pressing slide 114 is slidably disposed in the guide groove and is connected to the output end of the knife pressing cylinder 112. The knife pressing cylinder 112 drives the knife pressing slide 114 to move up and down. A limit block 115 is provided on the outer wall of the knife pressing slide 114. The limit block 115 extends through the guide groove to the outer side of the knife pressing guide seat 113.

[0078] A limit frame 116 is provided on the outer side of the limit block 115; a limit groove 117 is provided in the middle of the limit frame 116; the limit frame 116 is fixedly mounted on the outer side wall of the press knife guide seat 113 so that the limit block 115 is embedded in the limit groove 117; when the press knife slide 114 moves up and down, it is limited to the extreme position by the limit groove 117 and the limit block 115;

[0079] The bevel knife seat 118 is connected to the lower part of the knife pressing slide 114 , and an inclined mounting surface is provided on one side of the bottom of the bevel knife seat 118 ; the blade 1110 is fixed on the mounting inclined surface of the bevel knife seat 118 by a clamping block 119 .

[0080] The cutting assembly 11 of the present invention adopts a vertical design. The cutting assembly 11 is connected to the third slide rail 10 through the cutting seat 111, and is connected to the output end of the cutting cylinder 91 through a cutting knife guide seat 113 arranged on the side wall of the cutting seat 111. The cutting cylinder 91 drives the cutting seat 111 to move along the direction of the third slide rail 10 to cut the fuse 02; in particular, a cutting knife pressing cylinder 112 is also provided on the cutting seat 111. The cutting knife pressing cylinder 112 not only drives the cutter 1110 to move downward to the cutting position but also has a cutting knife pressing function, that is, before cutting, when the cutter 1110 moves downward and touches the terminal surface, it continues to give the cutter 1110 a predetermined setting of descending stroke, so that the cutter 1110 is in a partially bent state, thereby ensuring that the cutter surface is close to the terminal 03 while having a certain thickness change space. When the thickness change space is greater than the assembly error, the cutting accuracy problem caused by the assembly error can be effectively avoided. However, if the cutter 1110 is set vertically in the existing manner, the pressing function cannot be achieved (a vertically set cutter directly presses against the surface of the fuse when it descends and cannot bend). Therefore, the premise of pressing the cutter is that the cutter 1110 is set at an angle. While setting the cutter 1110 at an angle, the front cutting blade line a and the fuse cutting line b can be aligned with each other, which plays a guiding and limiting role in the cutting process, effectively ensuring the accuracy of the cutting position. In addition, this method also allows the blade surface of the cutter 1110 to contact the surface of the terminal 03, thereby effectively reducing the damage to the surface of the terminal 03 or the damage to the cutter 1110 during cutting. At the same time, the present invention uses a press knife guide seat 113 as a guide and limiting structure when the press knife descends. A press knife cylinder 112 disposed on the top of the cutting seat 111 drives a press knife slide 114 slidably disposed in a guide groove of the press knife guide seat 113 to move up and down, thereby driving an inclined knife seat 118 disposed at the bottom of the press knife slide 114 to move up and down. The cutter 1110 is fixed by an inclined mounting surface of a clamping block 119 disposed on one side of the bottom of the inclined knife seat 118. A limit frame 116 is also provided on the side of the press knife guide seat 113. By sliding an outwardly protruding limit block 115 disposed on the outer wall of the press knife slide 114 within a limit groove 117 of the limit frame 116, the cutter 1110 is limited to an extreme position during its lifting and lowering movement, thereby preventing the press knife slide 114 from falling due to loose installation or excessive downward pressure, resulting in deviation from the cutting position.

[0081] like Figure 2As shown, as an embodiment of the present invention, the present invention also includes a pressing assembly, which is arranged between the two groups of cutting assemblies 11 so as to press the fuse 0 to be cut from above; the pressing assembly includes a pressing support 12, a pressing cylinder 13 and a pressing block 14, wherein the pressing support 12 is vertically arranged on the bottom plate of the bracket 4; the pressing cylinder 13 is vertically arranged on the side wall of the pressing support 12; the pressing block 14 is connected to the output end of the pressing cylinder 13, and is driven by the pressing cylinder 13 to press the fuse 0 from top to bottom.

[0082] like Figures 1 to 13 As shown in FIG. 1 , as an embodiment of the present invention, the fuse cutting process of the automatic fuse cutting device of the present invention includes the following process steps:

[0083] S1. Fuse placement: Place the fuse to be cut in the fixture on the side of the automatic fuse cutting device;

[0084] S2. Pressing: The pressing assembly presses the fuse in the fixture in step S1 from above;

[0085] S3. Moving the blade: The horizontal moving assembly and the vertical moving assembly installed on the machine base respectively drive the blade to move in the horizontal plane, so that the blade moves to the top of the fuse to be cut;

[0086] S4, knife pressing: After the knife is moved into position in step S3, the knife pressing cylinder of the cutting assembly drives the knife blade to gradually descend toward the fuse, aligning the blade surface line with the fuse cutting line, and then continues to press down to bend the blade to a certain angle, at which point the blade contacts the fuse;

[0087] S5, obliquely cutting the fuse: After the knife pressing is completed in step S4, the oblique drive assembly drives the blade to move in an oblique downward direction, and the blade cuts the cutting portion of the fuse along the fuse cutting line.

[0088] like Figures 1 to 13 As shown, as one embodiment of the present invention, a fuse cutting machine includes an automatic fuse cutting device.
