Description

Technical Field

[0001] The present invention relates to the technical field of electronic protection components, and in particular to a device and method for manufacturing a fuse outer cap. Background Art

[0002] A fuse is a protective device that generates heat to melt the fuse element, thereby disconnecting the circuit when the current exceeds a specified value for a period of time. Currently, fuses are widely used in various circuits, such as the entire circuit of electric vehicles, as short-circuit and overcurrent protection devices. A fuse typically consists of a fuse element for interrupting the current, an outer cap that connects the fuse element to the circuit, and a fusible tube that connects the outer cap to house the fuse. However, conventional fuse caps are typically operated manually, which results in high costs, low efficiency, and unstable product quality.

[0003] Therefore, there is a need in the art for an apparatus for manufacturing a fuse outer cap with high production efficiency and low cost. Summary of the Invention

[0004] The present invention aims to provide an apparatus for manufacturing a fuse outer cap that can solve at least some of the above problems.

[0006] According to one aspect of the present invention, there is provided an apparatus for manufacturing outer caps of fuses, the apparatus comprising: a workbench on which is provided an outer cap feeding device, an outer cap feeding channel connected to the discharging end of the outer cap feeding device, and an outer cap discharging device connected to the discharging end of the outer cap feeding channel, wherein the outer cap feeding channel is sequentially defined as a dot-feeding position, a tin-feeding position and a gasket position on the path from the outer cap feeding device to the outer cap discharging device; a flux dot-feeding device located downstream of the outer cap feeding device, which is configured to add flux to the outer cap located at the dot-feeding position of the outer cap feeding channel; a tin-feeding and tin-cutting device located downstream of the flux dot-feeding device, which is configured to add tin wire to the outer cap located at the tin-feeding position of the outer cap feeding channel; a tin-feeding and tin-cutting device located downstream of the tin-feeding and tin-cutting device a gasket feeding device downstream of the device, which is configured to add gaskets to the outer caps located at the gasket position of the outer cap feeding channel; a driving device, which is configured to drive the flux dosing device, the tin feeding and cutting device and the gasket feeding device; a heating and tinning device located downstream of the gasket feeding device, which is configured to perform a tinning operation on the outer caps located at the outer cap feeding channel; a control device electrically connected to the outer cap feeding device, the flux dosing device, the tin feeding and cutting device, the gasket feeding device, the heating and tinning device, the outer cap discharging device and the driving device respectively, and used to control the operation of the outer cap feeding device, the outer cap discharging device, the flux dosing device, the tin feeding and cutting device, the gasket feeding device and the heating and tinning device.

[0026] With reference to the accompanying drawings, a schematic diagram of the apparatus for manufacturing a fuse cap disclosed in the present invention is described in detail. Although the drawings are provided to illustrate some embodiments of the present invention, they are not necessarily drawn to the dimensions of a specific embodiment, and certain features may be enlarged, removed, or partially cut away to better illustrate and explain the disclosure of the present invention. Some components in the drawings may be repositioned as needed without affecting the technical effect. The phrase "in the drawings" or similar terms appearing in the specification do not necessarily refer to all drawings or examples.

[0027] Certain directional terms used in the following description of the drawings, such as "inner," "outer," "above," "below," and other directional terms, should be understood to have their normal meanings and refer to those directions when the drawings are normally viewed. Unless otherwise indicated, the directional terms used in this specification are generally in accordance with conventional directions understood by those skilled in the art.

[0028] The terms "first", "first", "second", "second" and similar terms used in the present invention do not indicate any order, quantity or importance, but are used to distinguish one component from other components.

[0029] The terms "joining", "connection" and similar terms used in the present invention include both indirect connection of two components with the aid of an intermediate layer (such as adhesive, welding agent, etc.) or an intermediate piece (such as a connector, transition piece, etc.), and direct connection of two components without the aid of any intermediate layer (such as adhesive, welding agent, etc.) or intermediate piece (such as a connector, transition piece, etc.).

[0030] Figures 1 to 5By way of example, the present invention illustrates an apparatus 1 for manufacturing fuse caps. This apparatus 1 is used to process fuse caps through multiple steps and then discharge the processed caps. The entire process requires no manual intervention, significantly reducing labor costs and improving production efficiency. The apparatus 1 includes a workbench 111, a cap feeding device 12 secured to the workbench 111, for example, by bolts; a cap feeding channel 13; a flux dispensing device 15; a tin feeding and cutting device 16; a gasket feeding device 17; a tin heating and dissolving device 18; a cap discharging device 14; and a control device secured within a work cabinet 112, for example, secured to the workbench 111 by bolts.

[0031] Specifically, the discharge end of the outer cap feeding device 12 can be aligned with the feed end of the outer cap feeding channel 13 so that the outer caps, such as copper caps, stored in the outer cap feeding device 12 can be arranged in a unique state and fed into the outer cap feeding channel 13 in sequence. The discharge end of the outer cap feeding channel 13 can be located above the heating and tinning device 18. The outer cap feeding channel 13 is defined with a dosing position, a tin feeding position and a gasket position in sequence on the path from the outer cap feeding device 12 to the heating and tinning device 18. The free ends of the flux dosing device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 are suspended above the dosing position, the tin feeding position and the gasket position of the outer cap feeding channel 13, respectively. The discharge end of the heating and tinning device 18 can be connected to the outer cap discharge device 14. Among them, the outer cap sent out by the outer cap feeding device 12 passes through the bottom of the flux injection device 15, the tin feeding and cutting device 16, and the gasket feeding device 17 along the outer cap feeding channel 13 in sequence, and is sent to the heating and tinning device 18 for processing in sequence, so that flux, tin wire and gasket are added in the outer cap in sequence and heated to make the outer cap, and the outer cap is sent to the outer cap discharging device 14 by the heating and tinning device 18.

[0032] Among them, the output shaft of the driving device 22 can be connected to the flux dot-pouring device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 to simultaneously drive the flux dot-pouring device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 to move, so that the equipment 1 can perform the operations of adding flux, tin wire and gasket synchronously at the dot-pouring position, tin feeding position and gasket position of the outer cap material feeding channel 13. It has a simple structure, efficient operation and can reduce the cost of the equipment 1.

[0033] Among them, the control device can be electrically connected to the outer cap feeding device 12, the flux dot injection device 15, the tin feeding and cutting device 16, the gasket feeding device 17, the heating and tinning device 18, the outer cap discharging device 14 and the driving device 22 respectively to control the operation of the outer cap feeding device 12, the flux dot injection device 15, the tin feeding and cutting device 16, the gasket feeding device 17, the heating and tinning device 18, the outer cap discharging device 14 and the driving device 22, such as the start-up, shutdown and operating speed of each device.

[0034] Exemplarily, the outer cap feeding device 12, the flux dosing device 15, the tin feeding and cutting device 16, the gasket feeding device 17, the heating and tinning device 18 and the outer cap discharging device 14 can be installed with an induction switch for sensing signals such as whether the outer cap feeding device 12 is out of material, whether the flux is out of material or whether the outer cap reaches the bottom of the flux dosing device 15, whether the tin wire is out of material or whether the outer cap reaches the bottom of the tin feeding and cutting device 16, whether the gasket is out of material or whether the outer cap reaches the bottom of the gasket feeding device 17, whether the outer cap reaches the feed point of the heating and tinning device 18, and sends the sensed signals to the control device, which controls each device in response to each sensing signal.

[0035] Specifically, the control device controls the outer cap feeding device 12 to start and controls the feeding speed of the outer cap feeding device 12 to feed the outer cap to the outer cap feeding channel 13. When the outer cap moves to below the free end of the flux dot injection device 15, the control device controls the control valve of the flux dot injection device 15 to open and add flux into the outer cap. Then, when the outer cap reaches below the free end of the tin feeding and cutting device 16, the control device controls the tin feeding and cutting device 16 to start and add tin wire into the outer cap. Next, when the outer cap reaches below the free end of the gasket feeding device 17, the control device controls the gasket feeding device 17 to start and add a gasket into the outer cap. It can be understood that when processing three or more outer caps, the flux dot injection device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 can be driven by the driving device 22 to perform three operations synchronously, thereby greatly improving the production efficiency of the outer caps. The outer cap then moves along the outer cap feeding channel 13 until it moves and leaves the outer cap feeding channel 13 and reaches the feed end of the heating and tinning device 18. The control device controls the heating and tinning device 18 to heat the outer cap. After heating, the periphery of the melted tin wire can wrap around the gasket, so that the gasket of the outer cap obtained subsequently is not easy to fall off. Finally, the outer cap arrives at the outer cap discharging device 14. The control device controls the outer cap discharging device 14 to start and move the outer cap to the storage device. It can be understood that by controlling the operating speed of the outer cap feeding device 12, the flux dosing device 15, the gasket feeding device 17, the heating and tinning device 18 and the outer cap discharging device 14 and the moving speed of the outer cap on the outer cap feeding channel 13 by the control device, it is possible to continuously and repeatedly process the outer cap material to obtain the outer cap finished product.

[0036] Optionally, the flux dot-dotting device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 can be located on the same side of the outer cap feeding channel 13, and the working fixture 19 can be set on the workbench 111 and located on the side of the outer cap feeding channel 13 opposite to the flux dot-dotting device 15, so as to move the outer cap from the outer cap feeding device 12 on the outer cap feeding channel 12 from the dot-dotting position to the tin feeding position and from the tin feeding position to the gasket position.

[0037] Among them, the dot-filling position, tin-feeding position and gasket position on the outer cap feeding channel 13 are all provided with fixed positioning parts on the inner side of the side wall adjacent to the flux dot-filling device 15, and the dot-filling position, tin-feeding position and gasket position on the outer cap feeding channel 13 are extended to form a through hole 131 on the side wall adjacent to the working fixture 19. The end of the working fixture 19 facing the outer cap feeding channel 13 is constructed to extend through the through hole 131 of the outer cap feeding channel 13 and enter the outer cap feeding channel 13. When the outer caps on the outer cap feeding channel 13 are sequentially sent to the dot-filling position, tin-feeding position and gasket position on the outer cap feeding channel 13, they cooperate with the fixed positioning parts to coordinate and position the outer caps below the free ends of the flux dot-filling device 15, the tin-feeding and cutting device 16 and the gasket feeding device 17 for easy processing. In addition, the working fixture 19 can also be driven by the driving device 22 to coordinate and synchronize the actions of the flux dispensing device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 to improve production efficiency.

[0038] In the following, the direction parallel to the extension direction of the outer cap material delivery channel 13 is referred to as the front-to-back direction, the direction perpendicular to the side wall of the outer cap material delivery channel 13 in the direction transverse to the extension direction of the outer cap material delivery channel 13 is referred to as the left-right direction, and the direction parallel to the side wall of the outer cap material delivery channel 13 in the direction transverse to the extension direction of the outer cap material delivery channel 13 is referred to as the up-down direction.

[0039] Furthermore, the working fixture 19 may include a base plate 192 fixed to the workbench 111, a first movable plate 193 provided above the base plate 192 and movable in the front-to-back direction, and a second movable plate 194 provided above the first movable plate 193 and movable in the left-to-right direction, so that the second movable plate 194 can move in the front-to-back direction and in the lateral left-to-right direction relative to the workbench 111. It is understandable that the movement directions of the first movable plate 193 and the second movable plate 194 may be opposite. Among them, the end of the second movable plate 194 facing the outer cap material delivery channel 13 may be constructed as a movable positioning member 191, so that the movable positioning member 191 can move in the front-to-back direction and in the left-to-right direction relative to the fixed positioning member provided on the side wall of the outer cap material delivery channel 13.

[0040] Optionally, the outer cap feeding channel 13 may be further provided with a stacking position, a material taking position, a buffer position, and a material discharge position, so that in the front-to-back direction, the stacking position, the material taking position, the buffer position, the dot-injection position, the tin feeding position, the gasket position, and the material discharge position are arranged in sequence. A material taking mechanism 20 and a buffer mechanism 21 are further provided at the end of the first movable plate 193 adjacent to the outer cap feeding device 12. The material taking mechanism 20 and the buffer mechanism 21 are suspended above the outer cap feeding channel 13 so as to be movable not only in the front-to-back direction but also in the up-down direction following the first movable plate 193.

[0041] In actual use, the number of movable positioning members 191 can be four. The outer caps are fed by the outer cap feeding device 12 and arranged sequentially at the stacking position. In the first motion state, the picker mechanism 20 and the buffer mechanism 21 align with the stacking position and the picker position, respectively, and move up and down to grab the outer caps at the stacking position and the picker position. The four movable positioning members 191 move left and right corresponding to the buffer position, the dot-dispensing position, the tin-feeding position, and the shim position, respectively, to grab the outer caps at these positions. In the second state, the pick-up mechanism 20, the buffer mechanism 21, and the four movable positioning members 191 move forward and backward together to transport the outer caps at the stacking position to the pick-up position, the outer caps at the pick-up position to the buffer position, the outer caps at the buffer position to the dot-feeding position, the outer caps at the dot-feeding position to the tin-feeding position, the outer caps at the tin-feeding position to the gasket position, and the outer caps at the gasket position to the discharge position. At this time, the movable positioning members 191 at the dot-feeding position, the tin-feeding position, and the gasket position correspond to the fixed positioning members to position each outer cap below the flux dot-feeding device 15, the tin-feeding and cutting device 16, and the gasket-feeding device 17 for processing. In the third motion state, the four movable positioning members 191 move left and right away from the outer cap feeding channel 13 to release the outer caps grasped by each movable positioning member 191. In the fourth motion state, the material taking mechanism 20, the buffer mechanism 21 and the four movable positioning members 191 all return to the initial positions in the first motion state along the front-rear direction to perform the first motion state again, and reciprocate thereby.

[0042] Optionally, the outer cap feeding device 12 is constructed as an outer cap vibrating disk 121 connected to the feeding end of the outer cap feeding channel 13 and an outer cap feeding mechanism 122 supporting the outer cap feeding channel 13 from below, and the outer cap vibrating disk 121 is used to orderly feed out the outer caps. In addition, the section of the outer cap feeding channel 13 located between the outer cap feeding mechanism 122 and the stacking position of the outer cap feeding channel 13 can also be constructed to have a slope in the up-down direction, and the section of the outer cap feeding channel 13 located between the discharge position and the discharge end of the outer cap feeding channel 13 can also be constructed to have a slope in the up-down direction, which cooperates with the outer cap feeding mechanism 122 which can be constructed as a vibrator to generate a forward lateral force under the combined action of vibration force and gravity to reliably convey the outer caps.

[0043] Optionally, the flux dosing device 15 can be constructed to include a dosing drive mechanism 151 provided on the workbench 111 and a dosing head 152 provided on the end of the dosing drive mechanism 151 adjacent to the outer cap delivery channel 13 and suspended above the dosing position of the outer cap delivery channel 13. In addition, an induction switch electrically connected to the control device can be provided on the dosing head 152 to detect whether the outer cap is at the dosing position. The dosing drive mechanism 151 can be driven by being connected to the output shaft of the drive device 22 via the flux delivery input end 153. Therefore, the dosing drive mechanism 151 can be electrically connected to the control device, and when the control device detects that there is an outer cap at the dosing position of the outer cap delivery channel 13, the control device controls the drive device 22 to drive the dosing drive mechanism 151, and then controls the opening and closing of the control valve of the dosing head 152, thereby controlling whether the flux is released or not.

[0044] Optionally, the tin feeding and cutting device 16 is constructed to include a tin feeding mechanism 161 fixed on the workbench 111 and a tin cutting mechanism 162 connected to the tin feeding mechanism 161. The tin feeding mechanism 161 can be electrically connected to the control device, and the tin cutting mechanism 162 can be connected to the output shaft of the driving device 22 via the tin feeding wire input end 163 and driven to move up and down. In addition, the tin cutting mechanism 162 can be provided with an induction switch electrically connected to the control device to detect whether the outer cap is in the tin feeding position. Therefore, when the control device receives that the outer cap has arrived at the tin feeding position of the outer cap feeding channel 13 below the tin feeding and cutting mechanism 162, it controls the tin feeding mechanism 161 to feed tin and drives the tin cutting mechanism 162 to cut tin, and the cut tin wire falls into the outer cap. Exemplarily, the tin feeding mechanism 161 can also be constructed to include a tin wire unwinding section, a tin wire straightening section, a tin wire detection section and a tin wire stepping section, so as to effectively transport the tin wire from the tin wire unwinding section to the bottom of the tin cutting mechanism 162, and the tin cutting mechanism 162 is cut by moving up and down.

[0045] Optionally, the gasket feeding device 17 may be configured to include a gasket vibrating disk 171, a gasket feeding channel 172 connected to the discharge end of the gasket vibrating disk 171, a discharge disk connected to the discharge end of the gasket feeding channel 172, and a gasket taking mechanism 173. The gasket vibrating disk 171 and the gasket taking mechanism 173 may both be controlled by a control device, and the gasket taking mechanism 173 may be connected to the output shaft of the driving device 22 via the gasket feeding input end 174, and be driven to move left and right and up and down relative to the gasket feeding channel 172 and the outer cap feeding channel 13. Specifically, when the induction switch on the gasket taking mechanism 173 detects that there is an outer cap on the outer cap delivery channel 13, the control device controls the gasket vibration disk 171 to vibrate, and the gaskets are delivered in order along the gasket delivery channel 172, and the control device controls the driving device 22 to drive the gasket taking structure to move up and down to adsorb the gasket and move left and right to move the gasket at the discharge end of the gasket delivery channel 172 to the outer cap on the gasket position of the outer cap delivery channel 13.

[0046] Optionally, the heating tinning device 18 can be constructed to include a feed turntable 181 connected to the discharge end of the outer cap feeding channel 13, a turntable fixture 182 whose outer periphery is located above the feed turntable 181 and whose rotation direction is opposite to that of the feed turntable 181, and a discharge turntable 183 located below the outer periphery of the turntable fixture 182 and whose rotation direction is opposite to that of the turntable fixture 182. Figure 1 Only the turntable portion of the turntable fixture is shown, while the fixture portion covering the upper side of the turntable portion and extending the outer periphery to cover the feed turntable 181 is not shown, and the outer periphery of the fixture portion can be provided with evenly spaced clamping teeth. Among them, an induction switch can be provided at the feed end of the turntable fixture 182. When an outer cap is received from the feed turntable 181, a signal is sent to the control device, and the control device controls the turntable fixture 182 to rotate and heat, and finally send it out from the discharge turntable 183. Preferably, the control device can control the turntable fixture 182 to heat the outer cap thereon in sections, such as heating at a first predetermined temperature for a first predetermined time, heating at a second predetermined temperature for a second predetermined time, and so on, so as to accurately control the tinning of the outer cap.

[0047] Optionally, the apparatus for manufacturing fuse outer caps may further include a cooling device between the turntable fixture 182 of the heating and tinning device 18 and the outer cap discharging device 14 to accelerate cooling of the outer cap. Optionally, the cooling device and the outer cap discharging device 14 may be integrated together to save space.

[0048] In actual application, a method for manufacturing fuse outer caps using equipment for manufacturing fuse outer caps may include: controlling the outer cap feeding device 12 to supply outer caps through a control device, and moving the outer caps along the outer cap feeding channel 13 from the outer cap feeding device 12 to the outer cap discharging device 14; controlling the driving device 22 to drive the flux injection device 15, the tin feeding and cutting device 16 and the gasket feeding device 17 through the control device, and controlling the heating and tinning device 18 to process the passing outer caps in sequence; controlling the outer cap discharging device 14 to receive the processed outer caps sent by the outer cap feeding channel 13 or the heating and tinning device 18 and send them out through the control device.
