Description

Technical Field

[0001] This invention relates to the field of processing equipment, and more particularly to a processing apparatus and method for a circuit breaker arc extinguishing mechanism. Background Technology

[0002] Traditional circuit breaker arc extinguishing mechanisms consist of arc-extinguishing plates installed in parallel at intervals on the circuit breaker housing. When the electric arc passes through the arc-extinguishing plates, it is divided into several short arcs, thus extinguishing the arc. The arc-extinguishing plates are of the same size and shape, and the processing equipment only needs to clamp multiple parallel arc-extinguishing plates at once, and then insert the arc-extinguishing plates into the circuit breaker housing at the same time.

[0003] However, such circuit breaker arc-extinguishing mechanisms require a large number of arc-extinguishing plates to meet the arc-extinguishing requirements of high-voltage systems, resulting in a large arc-extinguishing chamber. Excessive arc energy can cause the grid plates to ablate and deform, affecting subsequent breaking performance.

[0004] If the arc-extinguishing mechanisms of a circuit breaker are arranged at an angle and stacked, the arc is divided multiple times by the arc-extinguishing mechanisms, reducing the thickness of the arc-extinguishing mechanisms and achieving a thinner design. However, this type of arc-extinguishing mechanism requires high overall structural strength from the arc-extinguishing plates. Traditional processing equipment, which directly inserts the arc-extinguishing plates into the circuit breaker housing, cannot achieve the desired structural reinforcement.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0009] A further technical solution is that the feeding mechanism includes: a feeding frame, a material cylinder for winding the arc-extinguishing strip, a conveyor wheel rotatably mounted on the feeding frame, a guide groove rotatably connected to the feeding frame, and a shearing mechanism for cutting the arc-extinguishing strip; wherein, the material cylinder is rotatably mounted on the feeding frame; the arc-extinguishing strip is wound around the conveyor wheel and passes through the guide groove; and the shearing mechanism is hinged to the feeding frame.

[0010] A further technical solution is that the side platform includes a side support, a side plate that is tilted and rotatably disposed on the side support, a side rod that is slidably disposed within the side support, and a side block for placing the arc-extinguishing frame; wherein, the side plate and the side rod are engaged with each other, and the rotation of the side plate drives the side rod to rise and fall; the side block is disposed around the main platform on the side rod.

[0011] A further technical solution is that the pressure welding device includes: a pressure welding bracket disposed at a diagonal position of the arc extinguishing frame, a pressure welding transfer frame movably disposed on the pressure welding bracket, and a pressure welding rod rotatably disposed on the pressure welding transfer frame; wherein, the pressure welding transfer frame drives the pressure welding rod to approach the diagonal of the arc extinguishing frame, and the pressure welding rod rotates to contact the edges of adjacent arc extinguishing frames respectively.

[0012] A further technical solution is that the flipping device includes: a flipping table, a flipping frame rotatably disposed on the flipping table, and a flipping block movably disposed on the flipping frame; wherein, the arc-extinguishing plate is placed on the flipping frame, and the flipping blocks are close to each other to clamp the arc-extinguishing plate; the flipping frame reciprocates along the flipping table, and the two sides of the arc-extinguishing plate are stacked.

[0013] A further technical solution is that the coating device includes: a medium cylinder for storing the medium, a coating layer acting on the arc-extinguishing plate, and a cylinder block that reciprocates to move the outlet of the medium cylinder; wherein, the coating layer is installed at the outlet of the medium cylinder; the cylinder block opens the outlet of the medium cylinder, and the medium flows out; the cylinder block closes the outlet of the medium cylinder, pushing the medium into the coating layer.

[0014] A further technical solution is that the stacking mechanism includes: a stacking main frame, a clamping mechanism mounted on the stacking main frame, a stacking sub-frame rotatably mounted on the stacking main frame, and a welding mechanism mounted on the stacking sub-frame; wherein, the clamping mechanism clamps the arc-extinguishing plate, the stacking sub-frame drives the welding mechanism to move around the arc-extinguishing plate, and the welding mechanism welds the stacked positions of the arc-extinguishing plates.

[0015] A method for processing a processing device for a circuit breaker arc extinguishing mechanism includes the following steps: Material cutting and feeding steps: The conveyor wheel rotates and conveys the arc-extinguishing belt through the guide groove and inserts it into the platform groove. The block extends and abuts against one end of the arc-extinguishing belt. The material cutting mechanism cuts the arc-extinguishing belt. Repeat the above process to form several arc-extinguishing plates arranged at an angle. The block retracts and detaches from the arc-extinguishing plates. The arc-extinguishing frame is placed on the side block. The side plate rotates and pushes the side block and side rod to rise. The arc-extinguishing plates are placed at an angle in the arc-extinguishing frame. Pressure welding steps: The pressure welding frame moves the pressure welding rod closer to the diagonal position of the arc extinguishing frame. The pressure welding rod contacts the edge of the adjacent arc extinguishing frame on one side and performs pressure welding. After the pressure welding rod rotates, it contacts the edge of the adjacent arc extinguishing frame on the other side and performs pressure welding. The coating stacking process is as follows: the flipping blocks move closer together to clamp the arc-extinguishing plate; the cylinder block opens the medium cylinder outlet, allowing the medium to flow out and merge into the coating layer; the cylinder block closes the medium cylinder outlet, pushing the medium into the coating layer; the coating layer applies the medium to one side of the arc-extinguishing plate; the clamping mechanism clamps the arc-extinguishing plate and stacks it, the stacking sub-frame rotates along the stacking main frame, and the welding mechanism welds different sides of the stacked arc-extinguishing plates; the flipping frame rotates along the flipping table, and the stacked arc-extinguishing plates flip, repeating the above process.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) The feeding mechanism places one end of the arc-extinguishing belt on the main platform, and then cuts one end of the arc-extinguishing belt to form an arc-extinguishing piece. After repeating this several times, the arc-extinguishing pieces are placed side by side at an angle on the main platform. By freely cutting the arc-extinguishing belt, the arrangement of arc-extinguishing pieces of different lengths is achieved; the pressure welding device approaches the side platform and contacts the edge of the arc-extinguishing frame, so that the notch position of the arc-extinguishing frame is welded, and the arc-extinguishing piece and the arc-extinguishing frame are also welded; the pressure welding device rotates around the side platform and pressure welds the four sides of the arc-extinguishing piece and the arc-extinguishing frame; the arc-extinguishing frame restricts and fixes the arc-extinguishing piece, so that the arc-extinguishing piece will not deform or shift, and the arc-extinguishing pieces maintain a narrow gap; the coating device The medium is applied to the arc-extinguishing plate in a semi-solid state, and is only applied to the end face of the arc-extinguishing plate. Once solidified, the medium connects the arc-extinguishing plates. A stacking mechanism stacks the arc-extinguishing plates on one side of the applied medium. During stacking, the arc-extinguishing plates must be staggered in their tilt directions. After the medium is applied, the stacking mechanism can stack the arc-extinguishing plates from above, or the flipping device can flip the plates so the application position is downwards, allowing the stacking mechanism to stack them from below. During the stacking process, the flipping device rotates the arc-extinguishing plates multiple times to prevent unidirectional flow of the medium. The medium always flows near the stacking position of the arc-extinguishing plates, ensuring complete coverage and connection.

[0017] (2) The block extends out of the first side platform and abuts against the middle platform. The arc extinguishing plate is inserted into the platform groove, and the block abuts against one end of the arc extinguishing plate. The cover plate swings down to press down the arc extinguishing plate, so that the lower end of the arc extinguishing plate contacts the bottom surface of the platform groove. The cover plate continues to restrict the arc extinguishing plate. When the arc extinguishing frame moves up, it prevents the arc extinguishing plate from leaving the platform groove. The guide groove is pushed up to make the groove block leave the frame groove. After rotating the guide groove at a certain angle, the groove block moves to the corresponding frame groove. The guide groove is no longer under force. The first elastic device pushes the groove block into the corresponding frame groove to complete the adjustment of the guide groove angle to adapt to the change of the arc extinguishing plate tilt angle. Through the clamping of the fixed clamping block and the movable clamping block, the shearing process of the scissors does not affect the arc extinguishing plate on the guide groove.

[0018] (3) Place the arc extinguishing frame on the side block, and the side rod drives the side block and the arc extinguishing frame to rise, so that the arc extinguishing plate is placed inside the arc extinguishing frame, and the two ends of the arc extinguishing plate are placed on the inner surface of the arc extinguishing frame; since the cover plate continuously restricts the arc extinguishing plate, when the arc extinguishing frame moves up, it cannot drive the arc extinguishing plate to leave the platform groove, thus ensuring the accurate position of the arc extinguishing plate and the arc extinguishing frame; by rotating the pressure welding rod, the pressure welding rod contacts the edges of the adjacent arc extinguishing frames respectively, and the welding of the four sides of the arc extinguishing frame is completed by the pressure welding device at the diagonal position. After the arc extinguishing frame and the arc extinguishing plate are welded, an arc extinguishing plate is formed.

[0019] (4) The adsorption end of the adsorption tank is formed on both sides of the adsorption tank, which facilitates the adsorption of the side of the arc extinguishing plate to complete the clamping; the stacked plate sub-frame drives the welding mechanism to move in a circular path, and the welding head can always contact the arc extinguishing frame to complete the welding by moving the insulating frame.

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0030] Figure 1 A schematic diagram of the arc-extinguishing mechanism of a circuit breaker according to the first embodiment of the present invention is shown. Figure 2 A top view of the processing apparatus for the arc-extinguishing mechanism of a circuit breaker according to the first embodiment of the present invention is shown. (Combined with...) Figure 1 and Figure 2 As shown, the present invention discloses a processing device for a circuit breaker arc extinguishing mechanism, comprising: a stacking plate mechanism 6, a coating device 5, a pressure welding device 3, a main platform 1, a side platform 2 for placing the arc extinguishing frame, a flipping device 4 for flipping the arc extinguishing plate, and a feeding mechanism 7 for conveying the arc extinguishing plate.

[0031] Traditional circuit breaker arc-extinguishing mechanisms consist only of arc-extinguishing plates placed side-by-side, resulting in a slow arc-extinguishing process due to the limited number of plates. The circuit breaker arc-extinguishing mechanism described in this application comprises stacked arc-extinguishing plates. Each arc-extinguishing plate consists of an arc-extinguishing frame and arc-extinguishing plates arranged in parallel and at an angle.

[0032] An electric arc is separated once as it passes through a set of arc-extinguishing plates. When the arc passes entirely through stacked arc-extinguishing plates, the number of separations increases exponentially, achieving rapid arc extinguishing. Because the arc-extinguishing plates are angled, the arc is elongated as it passes between them, further increasing the arc length and thus the arc voltage drop, thereby increasing the arc extinguishing speed. A processing device for circuit breaker arc-extinguishing mechanisms is used to handle the production of new arc-extinguishing mechanisms.

[0033] The arc-extinguishing frame in the circuit breaker's arc-extinguishing mechanism is square. Because the arc-extinguishing plates are placed at an angle, plates of varying lengths are distributed within the frame. The plates and frame are welded together to form an integral arc-extinguishing plate structure. A mixture of resin and curing agent, specifically phenolic resin or epoxy resin, is applied between adjacent arc-extinguishing plates. This medium possesses good thermal conductivity and high-temperature resistance, absorbing the heat from the electric arc and accelerating its elongation and cooling. While achieving the same arc-extinguishing effect, the number of stacked arc-extinguishing plates can be reduced, resulting in a thinner and lighter circuit breaker arc-extinguishing mechanism.

[0034] To ensure the electric arc passes through each arc-extinguishing plate as required, the stacking precision of the arc-extinguishing plates is high. Stamping is performed at the upper and lower ends of the arc-extinguishing frame, forming notches 8 and frame pieces 81. Notches 8 are formed on the end face of the arc-extinguishing frame, and frame pieces 81 are located on the side of the notches 8, extending beyond the end face of the arc-extinguishing frame. When adjacent arc-extinguishing plates are stacked, the arc-extinguishing pieces contact each other, and the connection is completed after the medium solidifies. The arc-extinguishing frames then contact each other, and the frame pieces 81 on the upper arc-extinguishing frame are inserted into the notches 8 on the upper arc-extinguishing frames. The frame pieces 81 on the upper arc-extinguishing frames of the adjacent arc-extinguishing frames contact and adhere within the notches 8. The stacking mechanism 6 completes the welding of the frame pieces 81 on the upper arc-extinguishing frames of the adjacent arc-extinguishing frames and the welding at the stacking position of the arc-extinguishing frames. As the frame piece 81 is inserted into the notch 8, the overlapping and positioning of the arc-extinguishing frame is completed. At the same time, the mutual welding of the frame pieces 81 on the adjacent arc-extinguishing frames, the welding of the overlapping position of the arc-extinguishing frames, and the connection of the overlapping arc-extinguishing plates through the solidification of the medium make the arc-extinguishing plates form a solid whole after being stacked. Under the premise of making the arc-extinguishing mechanism of the circuit breaker thinner, the structural strength of the arc-extinguishing mechanism of the circuit breaker is guaranteed.

[0035] The presence of the frame piece 81 causes it to protrude from the side of the arc-extinguishing frame, forming an installation groove on the circuit breaker housing. When the arc-extinguishing mechanism of the circuit breaker is installed into the circuit breaker housing, the frame piece 81 is inserted into the installation groove, and the outer surface of the arc-extinguishing frame contacts the inner surface of the circuit breaker housing, thus completing the restriction and fixation of the arc-extinguishing mechanism of the circuit breaker to prevent loosening.

[0036] An arc-extinguishing belt is wound around the feeding mechanism 7. The feeding mechanism 7 conveys one end of the arc-extinguishing belt to the main platform 1, and then cuts one end of the arc-extinguishing belt to form arc-extinguishing pieces. After repeating this process several times, the arc-extinguishing pieces are placed side by side at an angle on the main platform 1. Because the arc-extinguishing pieces are placed at an angle, their lengths differ. At the same time, in order to separate small segments of the arc, the spacing between the arc-extinguishing pieces is narrow, making it impossible to use a clamping mechanism to clamp and place them to achieve a narrow spacing arrangement of arc-extinguishing pieces of different lengths. However, this application achieves a narrow spacing arrangement of arc-extinguishing pieces of different lengths by freely cutting the arc-extinguishing belt.

[0037] Side platform 2 is positioned around main platform 1 and moves up and down along it. A notch is formed at one corner of the arc-extinguishing frame to facilitate its placement on side platform 2. After placement, the notch closes, and subsequent pressure welding device 3 welds the notch. After side platform 2 rises, the arc-extinguishing frame is located on the outer periphery of main platform 1, allowing the arc-extinguishing plate to be placed inside the frame.

[0038] The pressure welding device 3 approaches the side platform 2 and contacts the edge of the arc-extinguishing frame, welding the notch of the arc-extinguishing frame and also welding the arc-extinguishing plate to the arc-extinguishing frame. The pressure welding device 3 rotates around the side platform 2 and pressure welds the four sides of the arc-extinguishing plate to the arc-extinguishing frame. The arc-extinguishing frame restricts and fixes the arc-extinguishing plate, preventing deformation and displacement, and maintaining a narrow gap between the arc-extinguishing plates.

[0039] The coating device 5 applies a coating medium to the arc-extinguishing plate. The medium is applied to the arc-extinguishing plate in a semi-solid state. The medium is only coated on the end face of the arc-extinguishing plate. The medium solidifies into a solid and connects the arc-extinguishing plates.

[0040] The stacking mechanism 6 stacks the arc-extinguishing plates on one side of the coating medium. During stacking, the arc-extinguishing plates must be staggered in their tilt directions. After the coating medium is applied, the flipping device 4 can either not flip the arc-extinguishing plates, with the coating position facing upwards, and the stacking mechanism 6 stacks the plates from above, or it can flip the plates so that the coating position faces downwards, allowing the stacking mechanism 6 to stack them from below. During the stacking process, the flipping device 4 drives the arc-extinguishing plates to flip multiple times, preventing unidirectional flow of the medium. The medium always flows near the stacking position of the arc-extinguishing plates, ensuring complete coverage and connection.

[0041] Figure 3 A front view schematic diagram of the main stage and side stage according to the first embodiment of the present invention is shown. (Combined with...) Figure 2 and Figure 3 As shown, the main platform 1 includes: a first platform 11, a platform groove 12 arranged side by side and inclined on the first platform 11, a block 13 movable on the first platform 11, and a cover plate 14 swinging on the first platform 11.

[0042] The first platform 11 includes a central platform 111, a first side platform 112, and a second side platform 113. The first side platform 112 and the second side platform 113 are located on both sides of the central platform 111. Platform grooves 12 are arranged side by side at an angle on the central platform 111, and the platform grooves 12 can be disassembled to adjust their spacing and tilt angle. The block 13 is movably mounted on the first side platform 112, and the cover plate 14 is swayably mounted on the second side platform 113.

[0043] The length of the platform groove 12 varies to correspond to the length of each arc-extinguishing plate. The block 13 comprises mutually perpendicular strips, and is driven by an electric cylinder to move closer to or further away from the intermediate platform 111. The upper end of the intermediate platform 111 is square, and the structure of the block 13 abuts against two adjacent sides of the upper end of the intermediate platform 111. A cover plate 14 is oscillatingly positioned on the upper end of the second side platform 113. The motor drive is connected to the oscillating position of the cover plate 14, and the cover plate 14 oscillates via the motor.

[0044] Block 13 extends out of the first side platform 112 and abuts against the middle platform 111. The arc extinguishing plate is inserted into the platform groove 12, and block 13 abuts against one end of the arc extinguishing plate. Cover plate 14 swings down to press down the arc extinguishing plate, so that the lower end of the arc extinguishing plate contacts the bottom surface of the platform groove 12. Cover plate 14 continuously restricts the arc extinguishing plate and prevents the arc extinguishing plate from detaching from the platform groove 12 when the arc extinguishing frame moves upward.

[0045] Figure 4 A left-side structural schematic diagram of the feeding mechanism according to the first embodiment of the present invention is shown. (In conjunction with...) Figures 2-4 As shown, the feeding mechanism 7 includes: a feeding frame 71, a material cylinder 72 for winding the arc extinguishing strip, a conveying wheel 73 rotatably mounted on the feeding frame 71, a guide groove 74 rotatably connected to the feeding frame 71, and a shearing mechanism 75 for cutting the arc extinguishing strip.

[0046] The feeding mechanism 7 can be mounted on a robotic arm or on other devices that can drive its movement. The material cylinder 72 is rotatably mounted on the feeding frame 71. The conveyor wheel 73 is driven to rotate by a motor, and the conveying speed of the arc-extinguishing belt is controlled by controlling its rotation speed.

[0047] A groove rod 741 is provided on the guide groove 74. The groove rod 741 is inserted into the feeding rack 71 and rotatably connected to the feeding rack 71. A groove block 742 is provided on the groove rod 741, and a plurality of rack slots 711 are formed around the groove rod 741 on the feeding rack 71. A first elastic device 743 is sleeved on the groove rod 741. The first elastic device 743 elastically pulls the groove rod 741 and the guide groove 74 downward, so that the groove block 742 is placed in the rack slot 711.

[0048] The tilt angle of the arc extinguishing plate determines the length of the electric arc. Different specifications of circuit breakers have different tilt angles for their arc extinguishing mechanisms. A larger tilt angle results in a longer arc length, while a smaller tilt angle results in a shorter arc length.

[0049] Pushing the guide groove 74 upward causes the groove block 742 to disengage from the frame groove 711. After rotating the guide groove 74 by a certain angle, the groove block 742 moves to the corresponding frame groove 711. At this time, the guide groove 74 is no longer under force. The first elastic device 743 pushes the groove block 742 into the corresponding frame groove 711, completing the adjustment of the angle of the guide groove 74 to adapt to the change of the tilt angle of the arc extinguishing plate.

[0050] Figure 5 A front view structural schematic diagram of the shearing mechanism according to the first embodiment of the present invention is shown. (Combined with...) Figures 2-5 As shown, the arc-extinguishing belt is wound around the conveyor wheel 73 and passes through the guide groove 74. The shearing mechanism 75 is hinged to the unloading frame 71. The shearing mechanism 75 includes: a fixed clamping block 751 fixed to the unloading frame 71, a movable clamping block 752 hinged to one end of the fixed clamping block 751, and a shear 753 hinged to the other end of the fixed clamping block 751. The side of the fixed clamping block 751 facing the shear 753 and the side of the movable clamping block 752 facing the shear 753 are located on the same plane. During the swinging process, the shear 753 contacts the side of the fixed clamping block 751 facing the shear 753 and the side of the movable clamping block 752 facing the shear 753, respectively.

[0051] The arc-extinguishing band passes between the fixed clamping block 751 and the movable clamping block 752. The movable clamping block 752 is driven to swing by a cylinder. The fixed clamping block 751 and the movable clamping block 752 clamp the arc-extinguishing band. The shears 753 is driven to swing by a cylinder and cuts the arc-extinguishing band to form arc-extinguishing plates. The clamping by the fixed clamping block 751 and the movable clamping block 752 ensures that the cutting process of the shears 753 does not affect the arc-extinguishing plates on the guide groove 74.

[0052] Combination Figure 3 As shown, the side platform 2 includes a side support 21 arranged vertically, a side plate 22 tilted and rotatably arranged on the side support 21, a side rod 23 slidably arranged in the side support 21, and a side block 24 for placing the arc extinguishing frame.

[0053] The side rod 23 is slidably mounted within the side bracket 21 in a vertical direction, and the side block 24 is positioned around the upper end of the side rod 23 around the central platform 111. A toothed profile 231 is formed on the side rod 23, and a spiral protrusion 221 is formed on the side disc 22. A cutout 211 is formed on the side bracket 21, exposing the toothed profile 231, allowing the protrusion 221 to engage with the toothed profile 231. Through the engagement of the protrusion 221 with the toothed profile 231, the side disc 22, driven by a motor, rotates, causing the side rod 23 to rise and fall.

[0054] The arc-extinguishing frame is placed on the side block 24, and the side rod 23 drives the side block 24 and the arc-extinguishing frame to rise, so that the arc-extinguishing plate is placed inside the arc-extinguishing frame, with both ends of the arc-extinguishing plate placed on the inner surface of the arc-extinguishing frame. Because the cover plate 14 continuously restricts the arc-extinguishing plate, it cannot drive the arc-extinguishing plate out of the slot 12 when the arc-extinguishing frame moves upward, thus ensuring the accurate positioning of the arc-extinguishing plate and the arc-extinguishing frame.

[0055] Combination Figure 2 As shown, the pressure welding device 3 includes: a pressure welding bracket 31 positioned diagonally opposite the arc-extinguishing frame; a pressure welding transfer frame 32 movably mounted on the pressure welding bracket 31; and a pressure welding rod 33 rotatably mounted on the pressure welding transfer frame 32. The pressure welding transfer frame 32 is driven by an electric cylinder, moving along the pressure welding bracket 31 towards or away from the diagonal position of the arc-extinguishing frame. The pressure welding rod 33 is mounted on an insulating bracket 331, which is rotatably mounted on the pressure welding transfer frame 32. The insulating bracket 331 is driven to rotate by a motor, thereby causing the pressure welding rod 33 to rotate. The pressure welding rod 33 is connected to a power source via a metal sheet.

[0056] The pressure welding moving frame 32 moves the pressure welding rod 33 closer to the diagonal of the arc-extinguishing frame. The pressure welding rod 33 first contacts the edge of the adjacent arc-extinguishing frame on one side. After the pressure welding rod 33 completes the pressure welding, the pressure welding moving frame 32 retracts a certain distance, leaving enough space for the pressure welding rod 33 to rotate. The pressure welding moving frame 32 then moves the pressure welding rod 33 closer to the diagonal of the arc-extinguishing frame again, and the pressure welding rod 33 contacts the edge of the adjacent arc-extinguishing frame on the other side, completing the pressure welding. By rotating the pressure welding rod 33, it contacts the edges of the adjacent arc-extinguishing frames respectively. The pressure welding device 3 at the diagonal position completes the welding of the four sides of the arc-extinguishing frame. After the arc-extinguishing frame and the arc-extinguishing plate are welded, the arc-extinguishing plate is formed.

[0057] After the pressure welding device 3 completes the pressure welding, the side rod 23 and the side block 24 move down to reset, the cover plate 14 swings to disengage from the arc extinguishing plate, and the stacking mechanism 6 clamps the arc extinguishing plate and moves it to the flipping device 4.

[0058] Figure 6 A top view of the flipping device according to a first embodiment of the present invention is shown. (Combined with...) Figure 1 , Figure 2 and Figure 6 As shown, the flipping device 4 includes: a flipping table 41, a flipping frame 42 rotatably mounted on the flipping table 41, and flipping blocks 43 movably mounted on the flipping frame 42. The flipping frame 42 is rotatably mounted on the flipping table 41 at both ends. The flipping frame 42 is driven to rotate by a motor, realizing the flipping of the arc-extinguishing plate. The arc-extinguishing plate is placed on the flipping frame 42, and the flipping blocks 43 clamp the arc-extinguishing plate close to each other. The flipping frame 42 reciprocates along the flipping table 41, realizing the stacking of the arc-extinguishing plate from both sides. The stacked arc-extinguishing plates are evenly distributed. After stacking, the flipping blocks 43 clamp the arc-extinguishing mechanism of the circuit breaker at the middle position to prevent the clamping from losing balance.

[0059] The flipping block 43 includes: a block body 431, a block notch 432 formed on the block body 431, and end blocks 433 movably disposed at both ends of the block body 431. A second elastic device 434 is fitted onto the end blocks 433, generating an elastic force that causes the end blocks 433 to clamp the arc-extinguishing frame. The flipping block 43 is driven to move relative to the block body 431, clamping the arc-extinguishing frame and fixing its four sides. When the block body 431 contacts the arc-extinguishing frame, the frame piece 81 is positioned in the block notch 432, accurately positioning the arc-extinguishing frame. The block notch 432, by accommodating the frame piece 81, restricts the arc-extinguishing frame, preventing it from shifting.

[0060] A blowing device is installed at the lower end of the flipping table 41. The blowing device blows gas toward the arc-extinguishing plate to accelerate the solidification of the medium. After the coating device 5 applies the medium to the arc-extinguishing plate, the stacking mechanism 6 stacks the arc-extinguishing plates. The medium needs to solidify quickly to connect the arc-extinguishing plates, so that the arc-extinguishing plates will not break the connection and fall off during the subsequent flipping process.

[0061] When the medium is in a semi-solid state, it flows downwards along the arc-extinguishing plate after application. This application uses a flipping frame 42 to repeatedly flip the arc-extinguishing plate, causing the medium to flow back and forth at the overlapping position. The flow range of the medium can cover the overlapping position of the arc-extinguishing plates, ensuring the connection of the overlapping positions. As the medium gradually solidifies, the thickness of the medium gradually increases, making the connection of the overlapping positions of the arc-extinguishing plates firm.

[0062] Figure 7 A front view schematic diagram of the coating device according to a first embodiment of the present invention is shown. (In conjunction with...) Figure 7 As shown, the coating device 5 includes: a medium cylinder 51 for storing the medium, a coating layer 52 acting on the arc-extinguishing plate, and a cylinder block 53 that reciprocates to move the outlet of the medium cylinder 51. The outlet of the medium cylinder 51 is located at the lower end of the medium cylinder 51, the cylinder block 53 is horizontally positioned at the lower end of the medium cylinder 51, and the coating layer 52 is installed at the outlet of the medium cylinder 51, located below the cylinder block 53.

[0063] The coating device 5 can be mounted on a robotic arm or on other devices that can drive the coating device 5 to move.

[0064] The outlet of the medium cylinder 51 forms an outlet cylinder 511. A coating layer 52 is installed at the lower end of the outlet cylinder 511, and a cylinder block 53 is movably positioned at the upper end inside the outlet cylinder 511. The upper end of the outlet cylinder 511 extends into the medium cylinder 51, and parallel cylindrical holes 512 are formed on the upper end of the outer surface of the outlet cylinder 511. The cylindrical holes 512 are formed in a strip-like, inclined shape. A heating tube 513 is installed inside the medium cylinder 51. The medium is stored inside the medium cylinder 51, submerging the heating tube 513, which heats the medium.

[0065] The cylinder block 53 opens the outlet of the medium cylinder 51, allowing the medium to flow out. The cylinder block 53 then closes the outlet of the medium cylinder 51, pushing the medium into the coating layer 52. A straight rod 531 is mounted on the cylinder block 53, passing through the medium cylinder 51 and connected to the drive end of an electric cylinder. The electric cylinder drives the cylinder block 53 to move up and down via the straight rod 531. The cylinder block 53 moves upward along the outlet cylinder 511, exposing the cylinder hole 512. The medium flows into the outlet cylinder 511 through the cylinder hole 512. The cylinder block 53 moves downward along the outlet cylinder 511, blocking the cylinder hole 512, and presses the medium into the coating layer 52.

[0066] The coating layer 52 comprises several stacked single layers 521. Each single layer 521 has a mesh structure made of metal, and the pore size of the single layer 521 gradually decreases from top to bottom. Due to the larger pore size of the upper single layer 521, the upper end of the coating layer 52 can store a certain amount of medium. As the cylinder block 53 presses the medium into the coating layer 52, the medium passes through several single layers 521, gradually becoming finer and more uniform. The lower end of the coating layer 52 contacts the arc-extinguishing plate. When the coating device 5 moves downward, the lower end of the coating layer 52 is compressed, and the medium is coated onto the arc-extinguishing plate.

[0067] Figure 8 A front view of the stacking mechanism according to a first embodiment of the present invention is shown. (Combined with...) Figure 8 As shown, the stacking mechanism 6 includes: a stacking main frame 61, a clamping mechanism 62 mounted on the stacking main frame 61, a stacking sub-frame 63 rotatably mounted on the stacking main frame 61, and a welding mechanism 64 mounted on the stacking sub-frame 63.

[0068] The stacking mechanism 6 can be mounted on a robotic arm or on other devices that can drive the stacking mechanism 6 to move and rotate, so that the stacking mechanism 6 can clamp the arc-extinguishing plates and stack them from above or below.

[0069] The clamping mechanism 62 includes: a clamping block 621, adsorption grooves 622 formed side-by-side and inclined on the clamping block 621, and a cavity 623 formed within the clamping block 621. The cavity 623 is connected to both the air intake source and the adsorption grooves 622. The adsorption ends of the adsorption grooves 622 are formed on both sides of the adsorption grooves 622, facilitating the adsorption of the sides of the arc-extinguishing plate to complete the clamping. The clamping mechanism 62 needs to clamp the arc-extinguishing plate. Specifically: the clamping block 621 is close to the arc-extinguishing plate, so that the arc-extinguishing plate is placed in the adsorption grooves 622, and the cavity 623 is connected to the air intake source. The arc-extinguishing plate is clamped by adsorbing the arc-extinguishing plate through the adsorption grooves 622. When the cavity 623 is disconnected from the air intake source, the arc-extinguishing plate can be placed.

[0070] A gear ring 611 is arranged around the main frame 61 of the stacked plates, and a gear 631 is rotatably arranged on the sub-frame 63 of the stacked plates, meshing with the gear ring 611. The gear 631 is driven to rotate by a motor, and the gear 631 rolls along the gear ring 611, causing the sub-frame 63 of the stacked plates to rotate around the main frame 61 of the stacked plates. The sub-frame 63 of the stacked plates drives the welding mechanism 64 to move around the arc-extinguishing plate, and the welding mechanism 64 welds the stacked position of the arc-extinguishing plate.

[0071] The welding mechanism 64 includes an insulating frame 641 that is movable on the stacked plate sub-frame 63 and a welding head 642 mounted on the insulating frame 641. The insulating frame 641 is driven by an electric cylinder, which moves the welding head 642 closer to or further away from the arc-extinguishing frame. The stacked plate sub-frame 63 drives the welding mechanism 64 along a circular movement path, and by moving the insulating frame 641, the welding head 642 can always be in contact with the arc-extinguishing frame to complete the welding.

[0072] Second embodiment: The processing method for the processing device of the arc extinguishing mechanism of the circuit breaker includes the following methods: Material cutting and feeding steps: According to the inclination angle of the platform groove 12, push the guide groove 74 upward and rotate the guide groove 74 at a certain angle, then place the groove block 742 in the corresponding frame groove 711, and adjust the rotation angle of the guide groove 74.

[0073] Block 13 extends out of the first side platform 112 and abuts against the middle platform 111. According to the length requirement of the arc extinguishing plate, the conveyor wheel 73 rotates to convey the arc extinguishing belt through the guide groove 74 and then inserts it into the platform groove 12. Block 13 extends out and abuts against one end of the arc extinguishing belt.

[0074] The shearing mechanism 75 cuts the arc-extinguishing band, the movable clamping block 752 swings to clamp and fix the fixed clamping block 751 and the movable clamping block 752, and the shears 753 swings to cut the arc-extinguishing band to form an arc-extinguishing plate.

[0075] Repeat the above process to form several inclined and parallel arc-extinguishing plates. The block 13 retracts and detaches from the arc-extinguishing plates, and the cover plate 14 swings down to restrict the arc-extinguishing plates.

[0076] The arc-extinguishing frame is placed on the side block 24. The side plate 22 rotates and pushes the side block 24 and the side rod 23 to rise. When the side block 24 rises to a certain height, the arc-extinguishing plates are placed side by side at an angle on the arc-extinguishing frame.

[0077] Pressure welding steps: The pressure welding frame 32 moves the pressure welding rod 33 close to the diagonal position of the arc extinguishing frame. The pressure welding rod 33 contacts the edge of the adjacent arc extinguishing frame on one side for pressure welding. After the pressure welding rod 33 rotates, it contacts the edge of the adjacent arc extinguishing frame on the other side for pressure welding. After pressure welding is completed, the arc extinguishing plate and the arc extinguishing frame form an arc extinguishing plate. The side plate 22 rotates in the opposite direction to push the side block 24 and the side rod 23 down.

[0078] The coating stacking process is as follows: After the stacking mechanism 6 clamps the arc-extinguishing plate, it moves into the flipping frame 42, and the flipping blocks 43 move closer together to clamp the arc-extinguishing plate. The frame piece 81 is placed in the block cut 432, the block body 431 clamps the arc-extinguishing frame, and the end block 433 clamps the arc-extinguishing frame.

[0079] The cylinder block 53 moves upward to open the outlet of the medium cylinder 51, and the medium flows out through the cylinder hole 512 and merges into the coating layer 52. The cylinder block 53 moves downward to close the outlet of the medium cylinder 51, and the cylinder block 53 pushes the medium into the coating layer 52. The coating device 5 moves downward, and the coating layer 52 applies the medium to one side of the arc-extinguishing plate. The flipping frame 42 can rotate or remain stationary to ensure that the side of the arc-extinguishing plate coated with the medium faces the stacking direction of the arc-extinguishing plates.

[0080] The flipping frame 42 can rotate along the flipping table 41 or not. After stacking, the arc-extinguishing plates can be left stationary or flipped. The clamping mechanism 62 clamps the arc-extinguishing plates and places them from above or below to ensure that the arc-extinguishing plates of adjacent arc-extinguishing plates are arranged in an alternating manner.

[0081] The sub-frame 63 rotates along the main frame 61, and the welding mechanism 64 welds different sides of the stacked arc-extinguishing plates. The above process is repeated.

[0082] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
