Description

Technical Field

[0001] The present application relates to the field of assembled fuses, and in particular to a locking riveting point device for fuse cores. Background Art

[0002] ‌A fuse is a device used for overcurrent protection, usually used in circuits to prevent equipment damage or fire caused by excessive current. ‌When the current in the circuit exceeds the set value, the fuse will melt, thereby cutting off the circuit and protecting the electrical equipment. The fuse is usually made of fusible alloy with a low melting point so that it can melt quickly when the current is too large.

[0003] refer to Figure 1 The fusible core 9 includes a fusible tube 91 and two end caps 92 . A variable-section melt is arranged in the fusible tube 91 , and the fusible tube 91 is filled with quartz sand. The two end caps 92 are respectively used to seal the two ends of the fusible tube 91 .

[0004] At present, a Chinese utility model patent with publication number CN212192054U discloses a device for assembling fuses, including a first shift turntable and a second shift turntable that do not overlap each other and a driving device for driving the first shift turntable and the second shift turntable, the first shift turntable and the second shift turntable are provided with spaced fixtures on the outer periphery; a transverse shift device forms an assembly line from the upstream fixture of the first shift turntable to the downstream fixture via the transverse shift device and the upstream fixture of the second shift turntable to the downstream fixture; from the upstream to the downstream of the assembly line, a melting tube feeding device, a lower end cap feeding device, a melt feeding device, a lower end cap welding device, a sand filling device, an upper end cap feeding device, an upper end cap welding device, a processing device, a detection device and a discharge device are sequentially spaced from the upstream to the downstream of the assembly line; a control device is electrically connected to the above devices to control their operation, wherein the detection device is used to detect the length and resistance of the fuse, and the processing device is used to lock the fuse.

[0005] The locking operation is used to reduce the diameter of the end of the end cap and abut it against the outer wall of the melting tube, so as to reduce the outflow of quartz sand from between the melting tube and the end cap. However, only by the locking operation, when the end cap is affected by the internal quartz sand top force or external force, the end cap is easy to move relative to the tube body, and even the end cap is separated from the tank body by rotation. The connection strength between the melting tube and the end cap is not high. Therefore, there is an urgent need for a device that can improve the connection strength between the melting tube and the end cap in the melting core. Summary of the invention

[0006] In order to improve the connection strength between the fusible tube and the end cap in the fusible core, the present application provides a locking riveting point device for the fusible core.

[0007] The present application provides a locking riveting point device for a fusible core, which adopts the following technical solution:

[0008] A locking and riveting point device for fuses comprises a frame, a feeding assembly, two locking assemblies, two riveting point assemblies, a flip assembly, a discharging assembly and a running assembly for clamping a fusible core, wherein the running assembly clamps the discharged fusible core and runs in the order of the locking assembly, the riveting point assembly, the flip assembly, the locking assembly and the riveting point assembly; the riveting point assembly comprises a four-claw cylinder and four rivets, the four-claw cylinder is arranged on the frame, the four rivets are respectively arranged on the four claws of the four-claw cylinder, and the rivets are used to abut against the side wall of the end cap and push into the fusible tube.

[0009] By adopting the above technical scheme, the molten core is stacked in the feeding assembly, and the molten core is operated by the operating assembly. The operating assembly first operates the molten core to the locking assembly, and the locking assembly locks the molten tube and the end cap at one end. Then the operating assembly operates the molten core to the riveting point assembly, and the piston rod of the four-claw cylinder contracts, and the four rivets approach the molten core until the rivets abut against the side wall of the end cap and push the end cap into the molten tube. After completing the above operations, the molten core is flipped by the flipping assembly, and the molten tube and the end cap at the other end are locked and riveted again by the locking assembly and the riveting point assembly, and finally the discharging assembly is sent out; the riveting point operation of the end cap and the molten tube can reduce the rotation of the end cap relative to the molten tube, and can increase the upper limit of the force of the end cap being lifted off by the quartz sand in the molten tube, thereby further improving the quality of the molten core.

[0010] Optionally, the feeding assembly includes a holding bin for storing molten cores, a conveying member, a clamping arm, and an intermittent transfer member for the molten cores to adapt to the operating intervals of the operating assembly, the conveying member is used to send the molten cores out of the holding bin in sequence, the intermittent transfer member includes a matching frame, a horizontal placement bar, a vertical cylinder, a horizontal cylinder, a pushing-out cylinder, and a turntable, the horizontal placement bar is provided with a plurality of placement grooves for placing the molten cores along the length direction of the horizontal placement bar, the vertical cylinder is used to drive the matching frame to move in the vertical direction, the horizontal cylinder is used to drive the vertical cylinder to move along the length direction of the horizontal placement bar, the matching frame is arranged on the frame, the matching frame is provided with a plurality of matching grooves along the length direction of the horizontal placement bar, the clamping arm is used to clamp the molten core on the transmission member into the placement groove, the pushing-out cylinder is used to push the molten core in the placement groove onto the turntable, and the molten core on the turntable is clamped by the operating assembly.

[0011] By adopting the above technical scheme, since the riveting point assembly and the locking assembly need time to operate the fusible core, the operating assembly needs to pause, and the intermittent transfer member is used to realize the intermittent operation of the fusible core stacked in the storage bin. The fusible core in the storage bin is transmitted through the transmission member, and the clamping arm is used to clamp the fusible core arranged on the transmission member in sequence, and the clamping arm clamps the fusible core into the matching groove of the matching frame, the piston rod of the vertical cylinder is extended, and the horizontal placement bar moves upward. At this time, the fusible core is clamped in the placement groove, and then the horizontal cylinder is contracted, so that the horizontal placement bar drives the fusible core to align with the adjacent matching groove, and then the piston rod of the vertical cylinder is contracted, and the fusible core enters the matching groove on the matching frame again, and repeating the above steps can make the fusible core move along the distribution of the matching groove in sequence, and finally the fusible core is placed on the turntable by the push-out cylinder, and the fusible core on the turntable is convenient for the operating assembly to circulate to subsequent workstations.

[0012] Optionally, the feeding assembly also includes a sand blowing and sand suction component, which is located between the transmission component and the intermittent transplanting component, and the sand blowing and sand suction component includes a sand blowing air pipe, an air pump, a sand suction pipe and a sand storage box. The air pump is arranged on the frame, one end of the sand blowing air pipe is arranged on the air pump, the sand suction pipe is located on the side of the molten core away from the sand blowing air pipe, and the sand storage box is used to store quartz sand collected by the sand suction pipe.

[0013] By adopting the above technical solution, the fused core located in the containing bin has not yet been locked, and part of the quartz sand will flow out from between the melting tube and the end cap. The air pump pumps air into the sand blowing air pipe, and the sand blowing air pipe blows the quartz sand adhered to the surface of the fused core into the sand suction pipe. Under the action of gravity, the quartz sand enters the sand storage box for subsequent secondary utilization of the quartz sand. Reducing the quartz sand on the surface of the fused core also facilitates the subsequent fused core to be smoothly connected to the placement groove of the horizontal placement bar.

[0014] Optionally, the feeding assembly also includes a concentricity detection part, which includes two detection cylinders, two detection sleeves, two detection sliding blocks, two detection springs, a rejection cylinder and a detection sensor. The two detection cylinders are located on both sides of the horizontal placement bar, the two detection sliding blocks correspond to the two detection cylinders, the detection sliding blocks are arranged on the piston rods of the detection cylinders, the two detection sleeves correspond to the two detection sliding blocks, the detection sleeves are slidably connected to the detection sliding blocks along the sliding direction of the detection sliding blocks, the two detection springs correspond to the two detection sleeves, the detection springs are used to keep the detection sleeves away from the detection sliding blocks, the detection sensor is arranged on the detection sliding blocks, and the rejection cylinder is used to push the molten core that does not meet the concentricity requirements away from the horizontal placement bar.

[0015] By adopting the above technical solution, the concentricity detection piece is used to detect the concentricity of the two end caps and the melting tube. If the concentricity of the end cap and the melting tube does not meet the requirements, the subsequent locking operation will easily make the end of the end cap unable to fit the outer wall of the melting tube, and quartz sand will easily flow out from between the end cap and the melting tube. During the concentricity detection process, the piston rods of the two detection cylinders are extended, and the detection cylinder drives the detection sliding block to move, so that the detection sleeve moves toward the end cap. When the concentricity of the end cap and the melting tube meets the requirements, the end cap will enter the detection sleeve. If the concentricity of the fusion tube does not meet the requirements, the end cap will abut against the outer wall of the detection sleeve, and the detection sleeve will move relative to the detection sliding block and cause the detection spring to contract until the detection sleeve abuts against the detection sensor. The detection sensor extends the piston rod of the rejection cylinder, so that the fusion core that does not meet the requirements is pushed out of the horizontal placement bar. Through the concentricity detection part, a batch of fusion cores that do not meet the concentricity requirements can be rejected before the locking operation and riveting point operation, so that subsequent operations can be carried out smoothly, thereby improving the qualified rate of the fusion core in completing the locking and riveting points.

[0016] Optionally, the locking assembly includes a locking four-claw cylinder and four arc bars, the locking four-claw cylinder is arranged on the frame, the four arc bars are respectively arranged on the claws of the locking four-claw cylinder, and the arc bar is used to abut against the end of the fuse end cap.

[0017] By adopting the above technical solution, the locking operation is used to abut the end of the end cap against the outer wall of the melting tube, and the flow assembly places the fusible core on the locking four-claw cylinder. The claws of the locking four-claw cylinder approach each other until the arc strip abuts against the outer wall of the end cap and one end of the end cap is pressed against the outer wall of the melting tube. The locking operation reduces the outflow of quartz sand from the gap between the end cap and the melting tube, and improves the matching strength between the end cap and the melting tube.

[0018] Optionally, the flipping assembly includes a flipping seat, a flipping motor, a double-headed cylinder, two flipping blocks and a sliding cylinder. The flipping seat is slidably connected to the frame in a direction approaching or away from the fuse, the flipping motor is arranged on the flipping seat, the cylinder body of the double-headed cylinder is arranged on the output shaft of the flipping motor, the two flipping blocks are respectively arranged on the two piston rods of the double-headed cylinder, and the sliding cylinder is used to drive the flipping seat to move.

[0019] By adopting the above technical scheme, since the locking assembly and the rivet point assembly only operate one end of the fuse tube and the end cap, a flipping assembly is required so that the equipment can subsequently operate the other end of the fuse tube and the end cap. During the flipping operation, the sliding cylinder drives the flip seat to move so that the fusible core is located between the two flipping blocks. The double-headed cylinder is started, and the two flipping blocks clamp the fusible core. Then the sliding cylinder is reset, so that the fusible core is away from the operating assembly, providing enough space for the fusible core to flip. The flipping motor is started, driving the double-headed cylinder to rotate. At this time, the fusible core flips, and the sliding cylinder is started again. The sliding cylinder drives the flip seat to move, so that the fusible core is located at the work station of the operating assembly again. The operating assembly can drive the fusible core to move toward the subsequent work station. The flipping assembly has a simple and reasonable structure, which is convenient for the staff to operate and maintain.

[0020] Optionally, the frame is provided with a detection component, which is located between the discharge component and the riveting point component. The detection component includes a lock detection component, a riveting point detection component and a waste removal component. The lock detection component includes a detection double-headed cylinder, two detection clamping blocks, a pushing cylinder and a lock CCD detector. The pushing cylinder is arranged on the frame, and the pushing cylinder drives the detection double-headed cylinder to move in a vertical direction. The two detection clamping blocks are respectively arranged on the piston rod of the detection double-headed cylinder. The detection clamping block is used to clamp the fuse core, and the lock CCD detector is used to detect whether the lock of the fuse core meets the requirements.

[0021] By adopting the above technical scheme, the locking CCD detects the locking of the fuse through the appearance of the fuse. When inspection is required, the inspection double-headed cylinder drives the two inspection clamping blocks to clamp the fuse to be inspected, and the pushing cylinder drives the inspection double-headed cylinder, and makes the locking of the fuse close to the locking CCD detector. The locking CCD detector inspects and records the appearance of the fuse. After the fuse is inspected, the cylinder is pushed to reset. The inspection double-headed cylinder loosens the two inspection clamping blocks, and the operating component transports the inspected fuse.

[0022] Optionally, the rivet point detection component includes a driving motor, a three-jaw cylinder and a rivet point CCD detector, the three-jaw cylinder is rotatably connected to the frame, the driving motor is used to drive the three-jaw cylinder to rotate, the three-jaw cylinder is used to clamp the fusible core, and the rivet point CCD detector is used to detect whether the rivet points of the fusible core meet the requirements.

[0023] By adopting the above technical solution, after the fusible core completes the lock detection, the operating component moves the fusible core to the riveting point detection station, the three-jaw cylinder clamps the fusible core, the driving motor drives the three-jaw cylinder to rotate, the three-jaw cylinder drives the fusible core to rotate, the riveting point CCD detector detects and records the rivet pads on the axis of the fusible core, and the transfer component transports the detected fusible core.

[0024] Optionally, the waste rejection component includes a waste pipe, a first waste pipe, a second waste pipe, a first waste box, a second waste box, a mounting plate and a selection cylinder, the waste pipe is arranged on the frame, the mounting plate is connected to the frame by sliding in a horizontal direction, the first waste pipe and the second waste pipe are both arranged on the mounting plate, the selection cylinder is used to drive the mounting plate to slide and align the first waste pipe or the second waste pipe with the waste pipe, the first waste box is used to receive the molten core that slides out of the first waste pipe and does not meet the locking requirements, and the second waste box is used to receive the molten core that slides out of the second waste pipe and does not meet the riveting point requirements.

[0025] By adopting the above technical scheme, when the locking detection component or the rivet point detection component detects that there is a problem with the locking or rivet point of the fusible core, the transfer component will pass the fusible core into the waste pipe, and classify the fusible cores with different problems through the mounting plate. When the fusible core has a locking problem, the selection cylinder will drive the mounting plate to move, so that the feed port of the first waste pipe coincides with the discharge port of the waste pipe, and the fusible core will enter the first waste box through the waste pipe and the first waste pipe in turn; when the fusible core has a rivet point problem, the selection cylinder will drive the mounting plate to move, so that the feed port of the second waste pipe coincides with the discharge port of the waste pipe, and the fusible core will enter the second waste box through the waste pipe and the second waste pipe in turn; the waste removal component separates the fusible cores with different problems, and the waste removal component only requires a single workstation to complete the classification operation, thereby speeding up the operation speed of the overall equipment.

[0026] Optionally, the operating component includes a mounting plate, a lifting cylinder, an operating motor and ten clamping cylinders. The mounting plate is rotatably connected to the frame, the operating motor is used to drive the mounting plate to rotate, the lifting cylinder is used to drive the mounting plate to move in a vertical direction, and the ten clamping cylinders are distributed circumferentially along the axis of the mounting plate. The ten clamping cylinders respectively correspond to the turntable, two locking assemblies, two rivet point assemblies, a flipping assembly, a rivet point detection component, a locking detection component, a waste rejection component and a discharge assembly.

[0027] By adopting the above technical solution, during the operation of the equipment, the operating component is used to bring the fusible core to different workstations. When the transfer equipment needs to change the workstation of the fusible core, the operating motor will drive the mounting plate to rotate, and the mounting plate will drive the clamping cylinder to move to the next workstation. When the fusible core needs to be separated from the operating component, the clamping cylinder will release the fusible core and start the lifting cylinder. The lifting cylinder will raise the mounting plate to leave space for the equipment to operate the fusible core. The operating component has a simple structure and is easy to operate.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] The rivet point assembly is used to push the side wall of the end cap on the fusible core into the fusible tube after the locking is completed, so as to reduce the end cap from moving relative to the fusible tube due to the force of pushing off, and to limit the relative rotation between the end cap and the fusible tube, thus greatly improving the strength of the fusible core;

[0030] Intermittent transfer parts allow the materials in the storage bin to be transported according to the interval time of the operating components;
