TECHNICAL FIELD
[0001] The present application relates to the field of processing equipment, in particular to a processing device and method for an arc extinguishing mechanism of a circuit breaker. BACKGROUND
[0002] The traditional arc extinguishing mechanism of the circuit breaker is an arc extinguishing sheet installed in parallel and spaced apart in the housing of the circuit breaker. When the electric arc passes through the arc extinguishing sheet, it is divided into several short arcs to achieve arc extinguishing. The arc extinguishing sheets are the same in size and shape, and the processing equipment only needs to clamp multiple arc extinguishing sheets in parallel at one time, and then insert the arc extinguishing sheets into the circuit breaker housing.
[0003] However, such an arc extinguishing mechanism of the circuit breaker requires a large number of arc extinguishing sheets to meet the arc extinguishing requirements of high-voltage systems, resulting in a large volume of the arc extinguishing chamber. If the electric arc energy is too large, it will cause the grid sheet to ablate and deform, affecting the subsequent breaking performance.
[0004] If the arc extinguishing mechanism of the circuit breaker is arranged in an inclined manner and stacked, the electric arc is divided multiple times through the arc extinguishing mechanism of the circuit breaker, reducing the thickness of the arc extinguishing mechanism of the circuit breaker to achieve thinning. However, the arc extinguishing mechanism with such a structure has high overall structural strength of the arc extinguishing sheet, and the traditional processing equipment directly inserts the arc extinguishing sheet into the circuit breaker housing, which cannot achieve the effect of structural reinforcement.

DETAILED DESCRIPTION
[0034] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined application purposes, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments.
[0035] Figure 1 Fig. 1 shows a schematic diagram of the front structure of the first embodiment of the laminating mechanism of the present application. Figure 2 Fig. 1 shows a schematic diagram of the front structure of the first embodiment of the laminating mechanism of the present application. Figure 1 and Figure 2 As shown in the drawings, the processing device of the circuit breaker arc extinguishing mechanism of the present application comprises a laminating mechanism 6, a brushing device 5, a pressure welding device 3, a main table 1, a side table 2 for placing the arc extinguishing frame, a turnover device 4 for turning over the arc extinguishing plate, and a feeding mechanism 7 for conveying the arc extinguishing pieces.
[0036] Among them, the traditional circuit breaker arc extinguishing mechanism only includes arc extinguishing pieces placed side by side, which is limited by the number of arc extinguishing pieces and the arc extinguishing process is slow. In the present application, the circuit breaker arc extinguishing mechanism is composed of laminated arc extinguishing plates. The arc extinguishing plate is composed of an arc extinguishing frame and arc extinguishing pieces arranged side by side and inclined.
[0037] The arc is separated once by a set of arc extinguishing plates, the arc is completely separated by the superimposed arc extinguishing plates, the number of times of arc separation is multiplied to improve the arc extinguishing speed. Since the arc extinguishing pieces in the arc extinguishing plates are arranged obliquely, the arc is elongated when passing between the arc extinguishing pieces, the arc length is increased, the arc voltage drop is further improved, and the arc extinguishing speed is improved. The processing device of the circuit breaker arc extinguishing mechanism should produce the new arc extinguishing mechanism.
[0038] The arc extinguishing frame in the circuit breaker arc extinguishing mechanism is square, the arc extinguishing pieces are arranged obliquely, the arc extinguishing pieces with different lengths are distributed in the arc extinguishing frame, and the arc extinguishing pieces and the arc extinguishing frame are welded to form an arc extinguishing plate with an integral structure. The medium mixed by the resin and the curing agent is brushed between the adjacent arc extinguishing plates. Specifically, the resin is phenolic resin or epoxy resin. The medium has good heat conductivity and high temperature resistance, absorbs the heat of the arc, accelerates the elongation and cooling of the arc. Under the premise of achieving the same arc extinguishing effect, the number of superimposed arc extinguishing plates can be reduced to realize the lightness and thinness of the circuit breaker arc extinguishing mechanism.
[0039] To ensure that the arc passes through each arc extinguishing plate as required, the superimposition precision of the arc extinguishing plate is high. The upper end and the lower end of the arc extinguishing frame are stamped to form a notch 8 and a frame piece 81 on the arc extinguishing frame. The notch 8 is formed on the end face of the arc extinguishing frame, the frame piece 81 is located on the side of the notch 8, and the frame piece 81 extends out of the end face of the arc extinguishing frame. When the adjacent arc extinguishing plates are superimposed, the arc extinguishing pieces are superimposed and contacted, the medium is solidified to complete the connection, the arc extinguishing frames are superimposed and contacted, the frame piece 81 on the arc extinguishing frame is inserted into the notch 8 on the adjacent arc extinguishing frame, the frame piece 81 on the adjacent arc extinguishing frame is contacted and fitted in the notch 8, and the superimposed plate mechanism 6 completes the welding of the frame piece 81 on the adjacent arc extinguishing frame and the welding of the superimposed position of the arc extinguishing frame. Since the frame piece 81 is inserted into the notch 8, the superimposition positioning of the arc extinguishing frame is completed, and the mutual welding of the frame piece 81 on the adjacent arc extinguishing frame, the welding of the superimposed position of the arc extinguishing frame, and the connection of the arc extinguishing pieces through the solidification of the medium make the arc extinguishing plates form a firm whole after superimposition, and ensure the structural strength of the circuit breaker arc extinguishing mechanism under the premise of lightness and thinness of the circuit breaker arc extinguishing mechanism.
[0040] The frame piece 81 protrudes from the side of the arc extinguishing frame due to the existence of the frame piece 81, and forms a mounting groove on the circuit breaker shell. When the circuit breaker arc extinguishing mechanism is installed in the circuit breaker shell, the frame piece 81 is inserted into the mounting groove, the outer surface of the arc extinguishing frame contacts the inner surface of the circuit breaker shell, and the restriction and fixation of the circuit breaker arc extinguishing mechanism are completed to avoid loosening.
[0041] The arc extinguishing belt is wound around the discharging mechanism 7, one end of the arc extinguishing belt is placed on the main table 1, and the arc extinguishing belt is cut to form arc extinguishing pieces. After repeating several times, the arc extinguishing pieces are placed on the main table 1 in parallel and obliquely. Due to the oblique placement of the arc extinguishing pieces, the lengths of the arc extinguishing pieces are different. In order to separate the small arc, the distance between the arc extinguishing pieces is narrow, so that the arc extinguishing pieces with different lengths cannot be placed in narrow distance by the clamping mechanism. The present application realizes the narrow distance arrangement of the arc extinguishing pieces with different lengths by the free cutting of the arc extinguishing belt.
[0042] The side table 2 is arranged around the main table 1 and is lifted along the main table 1. The arc extinguishing frame is formed with a notch at one corner position, which facilitates the placement of the arc extinguishing frame on the side table 2. After the placement is completed, the notch is closed, and the subsequent pressure welding device 3 welds the notch position. After the side table 2 is lifted, the arc extinguishing frame is located at the outer periphery of the main table 1, so that the arc extinguishing pieces are placed in the arc extinguishing frame.
[0043] The pressure welding device 3 is close to the edge of the arc extinguishing frame of the side table 2, so that the notch position of the arc extinguishing frame is welded, and the arc extinguishing pieces and the arc extinguishing frame are also welded. The pressure welding device 3 rotates around the side table 2 and pressure welds to weld the four edges of the arc extinguishing pieces and the arc extinguishing frame. The arc extinguishing frame limits and fixes the arc extinguishing pieces, so that the arc extinguishing pieces will not be deformed and deviated, and the narrow distance between the arc extinguishing pieces is maintained.
[0044] The coating device 5 acts on the arc extinguishing plate to coat the medium, and the medium is coated on the arc extinguishing plate in a semi-solid state. The medium will only be coated on the end surface position of the arc extinguishing plate, and the medium will be connected after being solidified into a solid.
[0045] The plate stacking mechanism 6 stacks the arc extinguishing plate on one side of the coating medium. When the arc extinguishing plate is stacked, the oblique direction of the arc extinguishing piece needs to be staggered. After the coating medium is completed, the overturning device 4 can overturn the arc extinguishing plate without overturning the arc extinguishing plate. The coating position of the arc extinguishing plate is upward, and the plate stacking mechanism 6 stacks the arc extinguishing plate from above. The overturning device 4 can also overturn the arc extinguishing plate, so that the coating position of the arc extinguishing plate is downward, and the plate stacking mechanism 6 stacks the arc extinguishing plate from below. The overturning device 4 drives the arc extinguishing plate to overturn several times during the stacking process, so as to avoid the one-way flow of the medium. The medium always flows near the stacking position of the arc extinguishing plate, and the medium can completely cover the stacking position of the arc extinguishing plate to ensure the connection.
[0046] Figure 3 The main view structural schematic diagram of the main table and the side table of the first embodiment of the present application is shown. As shown in combination with Figure 2 and Figure 3 The main table 1 comprises: a first block table 11, a table groove 12 arranged in parallel and obliquely on the first block table 11, a block body 13 movably arranged on the first block table 11, and a cover plate 14 swingably arranged on the first block table 11.
[0047] The first block table 11 includes a middle table 111, a first side table 112 and a second side table 113. The first side table 112 and the second side table 113 are located on both sides of the middle table 111. The table groove 12 is arranged in parallel and inclined on the middle table 111, and the table groove 12 can be disassembled to adjust the interval and the inclination angle. The block 13 is movably arranged on the first side table 112, and the cover plate 14 is swingably arranged on the second side table 113.
[0048] The length of the table groove 12 changes to correspond to the length of each arc-extinguishing piece. The block 13 includes mutually perpendicular strips, and the block 13 is driven by an electric cylinder to approach or move away from the middle table 111. The upper end of the middle table 111 is square, and the structure of the block 13 abuts against two adjacent edges of the upper end of the middle table 111. The cover plate 14 is swingably arranged at the upper end of the second side table 113. The motor driving end is connected to the swing arrangement position of the cover plate 14, and the cover plate 14 swings by the motor drive.
[0049] The block 13 extends out of the first side table 112 and abuts against the middle table 111, the arc-extinguishing piece is inserted into the table groove 12, and the block 13 abuts against one end of the arc-extinguishing piece. The cover plate 14 swings and presses down the arc-extinguishing piece, so that the lower end of the arc-extinguishing piece contacts the bottom surface of the table groove 12, and the cover plate 14 continuously limits the arc-extinguishing piece, avoiding the arc-extinguishing piece from being separated from the table groove 12 when the arc-extinguishing frame moves up.
[0050] Figure 4 A left view structural schematic diagram of the first embodiment of the material releasing mechanism is shown. In combination with the description of the first embodiment of the arc-extinguishing mechanism, the material releasing mechanism 7 includes a material releasing frame 71, a material cylinder 72 winding the arc-extinguishing belt, a conveying wheel 73 rotatably arranged on the material releasing frame 71, a guide groove 74 rotatably connected to the material releasing frame 71, and a shearing material mechanism 75 shearing the arc-extinguishing piece. Figures 2-4
[0051] The material releasing mechanism 7 can be mounted on a mechanical arm or other device capable of driving the material releasing mechanism 7 to move. The material cylinder 72 is rotatably arranged on the material releasing frame 71. The conveying wheel 73 is rotatably driven by a motor, and the conveying speed of the arc-extinguishing belt is controlled by controlling the rotation speed.
[0052] The guide groove 74 is provided with a groove rod 741 inserted into the material releasing frame 71 and rotatably connected to the material releasing frame 71. The groove rod 741 is provided with a groove block 742, and the material releasing frame 71 is formed with a plurality of frame grooves 711 around the groove rod 741. The groove rod 741 is provided with a first elastic device 743, which elastically pulls the groove rod 741 and the guide groove 74 downward, so that the groove block 742 is placed in the frame groove 711.
[0053] The inclination angle of the arc-extinguishing piece determines the length of the elongation of the electric arc. The inclination angle of the arc-extinguishing piece is different for different specifications of the circuit breaker arc-extinguishing mechanism. The greater the inclination angle of the arc-extinguishing piece, the longer the length of the elongation of the electric arc. The smaller the inclination angle of the arc-extinguishing piece, the shorter the length of the elongation of the electric arc.
[0054] The upward pushing of the guide slot 74 makes the slot block 742 disengage from the rack slot 711. After the guide slot 74 is rotated by a certain angle, the slot block 742 moves to the corresponding rack slot 711. At this time, the guide slot 74 is no longer under force, and the first elastic device 743 pushes the slot block 742 to move into the corresponding rack slot 711, thereby completing the adjustment of the angle of the guide slot 74 to adapt to the change in the inclination angle of the arc-extinguishing piece.
[0055] Figure 5 A front view structural schematic diagram of the material cutting mechanism of the first embodiment of the application is shown. As shown in the figure, Figures 2-5 The arc-extinguishing belt is wound around the conveying wheel 73 and passes through the guide slot 74, and the material cutting mechanism 75 is hingedly connected to the material placing rack 71. The material cutting mechanism 75 includes a fixed clamp block 751 fixed to the material placing rack 71, a movable clamp block 752 hingedly connected to one end of the fixed clamp block 751, and a scissors 753 hingedly connected to the other end of the fixed clamp block 751. The side of the fixed clamp block 751 facing the scissors 753 and the side of the movable clamp block 752 facing the scissors 753 are in the same plane. The scissors 753 contacts the side of the fixed clamp block 751 facing the scissors 753 and the side of the movable clamp block 752 facing the scissors 753 during swinging.
[0056] The arc-extinguishing belt passes between the fixed clamp block 751 and the movable clamp block 752. The movable clamp block 752 is swung by a pneumatic cylinder, and the fixed clamp block 751 and the movable clamp block 752 clamp the arc-extinguishing belt. The scissors 753 is swung by a pneumatic cylinder, and the scissors 753 cuts the arc-extinguishing belt to form the arc-extinguishing piece. The clamping of the fixed clamp block 751 and the movable clamp block 752 ensures that the cutting process of the scissors 753 does not affect the arc-extinguishing pieces on the guide slot 74.
[0057] As shown in the figure, Figure 3 The side table 2 includes a side support 21 arranged in the up-down direction, a side disc 22 arranged in an inclined and rotating manner on the side support 21, a side rod 23 arranged in the side support 21 in a sliding manner, and a side block 24 on which the arc-extinguishing frame is placed.
[0058] The side rod 23 is arranged in the side support 21 in a sliding manner in the up-down direction, and the side block 24 is arranged at the upper end of the side rod 23 around the middle table 111. The side rod 23 is formed with a tooth shape 231, and the side disc 22 is formed with a helical protrusion 221. The side support 21 is formed with a cutout 211 that exposes the tooth shape 231, so that the protrusion 221 engages with the tooth shape 231. By engaging the protrusion 221 with the tooth shape 231, the side disc 22 drives the side rod 23 to rise or fall when the side disc 22 is rotated by a motor.
[0059] 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 pieces are placed in the arc-extinguishing frame, and the two ends of the arc-extinguishing pieces are placed on the inner surface of the arc-extinguishing frame. Since the cover plate 14 continuously limits the arc-extinguishing pieces, the arc-extinguishing frame cannot drive the arc-extinguishing pieces to disengage from the table groove 12 when the arc-extinguishing frame is moved up, thereby ensuring the accurate position of the arc-extinguishing pieces and the arc-extinguishing frame.
[0060] Combining Figure 2 As shown in the figure, the pressure welding device 3 comprises: a pressure welding support 31 arranged at the diagonal position of the arc extinguishing frame, a pressure welding moving support 32 arranged on the pressure welding support 31, and a pressure welding strip 33 arranged on the pressure welding moving support 32. The pressure welding moving support 32 is driven by an electric cylinder, and the pressure welding moving support 32 moves towards or away from the diagonal position of the arc extinguishing frame along the pressure welding support 31. The pressure welding strip 33 is installed on an insulating support 331, the insulating support 331 is arranged on the pressure welding moving support 32 in a rotating manner, and the insulating support 331 is driven to rotate by a motor, thereby driving the pressure welding strip 33 to rotate. The pressure welding strip 33 is connected to a power source through a metal sheet.
[0061] The pressure welding moving support 32 drives the pressure welding strip 33 to approach the diagonal position of the arc extinguishing frame, the pressure welding strip 33 first contacts the edge of the adjacent arc extinguishing frame on one side, after the pressure welding strip 33 completes pressure welding, the pressure welding moving support 32 retreats by a certain distance, leaving enough space for the pressure welding strip 33 to rotate, the pressure welding moving support 32 drives the pressure welding strip 33 to approach the diagonal position of the arc extinguishing frame again, the pressure welding strip 33 contacts the edge of the adjacent arc extinguishing frame on the other side, and the pressure welding strip 33 completes pressure welding. By rotating the pressure welding strip 33, the pressure welding strip 33 contacts the edges of the adjacent arc extinguishing frames respectively, and the pressure welding device 3 at the diagonal position completes the welding of the four edges of the arc extinguishing frame. After the arc extinguishing frame and the arc extinguishing sheet are welded, the arc extinguishing plate is formed.
[0062] After the pressure welding device 3 completes pressure welding, the side rod 23 and the side block 24 move downward to reset, the cover plate 14 swings to separate from the arc extinguishing sheet, and the stacking plate mechanism 6 clamps the arc extinguishing plate and moves to the turnover device 4.
[0063] Figure 6 A top view structural schematic diagram of the turnover device of the first embodiment of the present application is shown. Combining Figure 1 , Figure 2 and Figure 6 As shown in the figure, the turnover device 4 comprises: a turnover table 41, a turnover support 42 arranged on the turnover table 41 in a rotating manner, and a turnover block 43 arranged on the turnover support 42 in a moving manner. The two ends of the turnover support 42 are arranged on the turnover table 41 in a rotating manner, the turnover support 42 is driven to rotate by a motor, thereby realizing the turnover of the arc extinguishing plate. The arc extinguishing plate is arranged on the turnover support 42, and the turnover blocks 43 are close to each other to clamp the arc extinguishing plate. The turnover support 42 rotates back and forth along the turnover table 41, thereby realizing the stacking of the arc extinguishing plates from both sides, the stacked arc extinguishing plates are evenly distributed, and after the stacking is completed, the turnover blocks 43 are clamped at the middle position of the arc extinguishing mechanism of the circuit breaker, thereby avoiding the loss of balance of clamping.
[0064] The turnover block 43 comprises a block body 431, a block notch 432 formed on the block body 431 and end blocks 433 movably arranged at both ends of the block body 431.

After the medium is applied on the arc extinguishing plate by the brushing device 5, the stacking mechanism 6 stacks and places the arc extinguishing plates, and the medium needs to be quickly solidified to connect the arc extinguishing plates, so that the arc extinguishing plates are disconnected and fall off during the subsequent turnover process of the arc extinguishing plates.
[0066] After the medium is in a semi-solid state after being applied, the medium will flow downwards along the arc extinguishing plate. The turnover frame 42 drives the arc extinguishing plate to repeatedly turn over, so that the medium reciprocally flows in the stacking position. The flowing range of the medium can cover the stacking position of the arc extinguishing plate, so that the connection of the stacking position of the arc extinguishing plate is ensured. As the medium gradually solidifies, the thickness of the medium gradually increases, so that the connection of the stacking position of the arc extinguishing plate is firm.

The lower end of the coating layer 52 contacts the arc extinguishing plate, and the lower end of the coating layer 52 is pressed when the coating device 5 moves downwards, and the medium is coated on the arc extinguishing plate.
