Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit breaker assembly, in particular to an assembly system for vacuum circuit breaker production and manufacturing and an assembly method thereof. BACKGROUND

[0002] As a kind of key power electronic components, the core of vacuum circuit breaker is high-voltage switch equipment for realizing arc extinguishing and insulation in vacuum environment, which is specially used for current on-off control and short-circuit fault protection in power system.

[0003] At present, in the manufacturing process of power electronic components of vacuum circuit breaker, the mainstream process is to assemble the internal structure of core power electronic component "vacuum arc extinguishing chamber" first, then to dock the interface perpendicular to the top of circuit breaker shell through mechanical arm, and to realize assembly through rotation. However, in this assembly link, due to the difference in the orientation of mechanical arm clamping vacuum arc extinguishing chamber, it is difficult to accurately ensure the accurate alignment of the joint (i.e. moving contact) of current transformer, which is a key power electronic component outside the arc extinguishing chamber, and the isolation knife seat above the insulating support during the rotation assembly process. This alignment deviation leads to poor contact between the front end of isolation knife seat and the joint, causing significant increase in contact resistance, especially when the deviation is large, which may even cause the phenomenon of refusal to operate or complete failure to connect. In order to solve this problem, manual or secondary rotation adjustment of arc extinguishing chamber is often required, which not only significantly reduces the production efficiency of power electronic component manufacturing, but also leads to the decrease of product qualification rate.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0033] Embodiment one: please refer to Figure 1 - Figure 11As shown, the assembly system for vacuum circuit breaker production and manufacturing provided by the embodiment comprises a base plate 1, a conveying assembly 2, a multi-link mechanical arm 3, a supporting assembly 4, a jaw assembly 5 and a correcting assembly 6, one end of the base plate 1 is provided with the conveying assembly 2 for conveying the shell of the vacuum circuit breaker, and the other end of the base plate 1 is provided with the multi-link mechanical arm 3 for hoisting and conveying the components, the multi-link mechanical arm 3 is located on one side of the conveying assembly 2, and is used for transporting the vacuum interrupter and the insulating support clamped by the upper jaw assembly 5 to the corresponding shell on the conveying assembly 2 for assembly, and is responsible for the adjustment of the angle and the position during the assembly process, so as to ensure that the vacuum interrupter and the insulating support can be fully installed on the corresponding interfaces above the shell.

[0034] The frontmost link of the multi-link mechanical arm 3 is fixed with a driver 311, a sleeve 312 is fixed on the output end of the driver 311, an adjusting rod 313 is movably sleeved in the sleeve 312, and a regulating mechanism 32 for driving the displacement movement of the adjusting rod 313 is fixed on the sleeve 312, the driver 311 is used for controlling the inclination angle adjustment of the adjusting rod 313 and the supporting assembly 4 on the front end, so as to realize the adjustment of the vertical angle installation of the vacuum interrupter and the shell and the inclined angle installation of the insulating support and the shell.

[0035] The front end of the adjusting rod 313 is fixed with the supporting assembly 4, two groups of jaw assemblies 5 for clamping and fixing the vacuum interrupter and the insulating support are installed on the supporting assembly 4, and the correcting assembly 6 for calibrating the position of the current transformer joint on the side of the vacuum interrupter is installed on the supporting assembly 4.

[0036] Further, the conveying assembly 2 comprises a caterpillar conveyor 21 fixed on the base plate 1, side guards 22 are arranged on both sides of the caterpillar conveyor 21, and a limiting mechanism 23 is installed on the side guards 22.

[0037] More specifically, when the caterpillar conveyor 21 operates, the shell of the vacuum circuit breaker is conveyed by the caterpillar transmission mode, and a position sensor (for example, an optical, proximity or ultrasonic sensor) connected with the PLG is arranged, so that the shell can be automatically started and stopped when it is conveyed to the set position.

[0038] Further, the limiting mechanism 23 comprises side plates 231 fixed on the two side guards 22, strip plates 232 movably connected on the opposite inner sides of the side plates 231, and moving rods 233 penetrating the side of the side plates 231 are arranged on the back of the strip plates 232.

[0039] The side of the moving rod 233 is provided with a limiting sliding groove 234 along the length direction thereof, and a positioning rod 235 is threadedly connected on the side plate 231, and one end of the positioning rod 235 is abutted in the limiting sliding groove 234.

[0040] More specifically, the distance between the two side plates 231 is adjusted by the push-pull moving rod 233 to limit the size of the shell of different sizes, to ensure stable conveying of the shell on the crawler conveyor 21, and to avoid tilting and deviation.

[0041] It should be further explained that the shell is vertically placed on the crawler conveyor 21, and when conveying to the designated position, the vacuum interrupter clamped on one set of jaw assemblies 5 is located at the corresponding interrupter mounting position on the shell, and the insulating support clamped on the other set of jaw assemblies 5 is located at the corresponding insulating support mounting position on the shell.

[0042] Further, a plurality of circular holes 236 are equidistantly formed on the surface of the strip plate 232, and a ball 237 is rotatably connected in the circular hole 236.

[0043] More specifically, when the crawler conveyor 21 conveys the shell, the side part is attached to the ball 237, thereby reducing the resistance between the shell and the strip plate 232, and ensuring that the shell can be stably and smoothly conveyed.

[0044] Further, the control mechanism 32 includes a control motor 321 fixed on the sleeve 312, a drive gear 322 fixed on the output end of the control motor 321, and a control groove 314 formed on the side of the adjusting rod 313 along the length direction, and the drive gear 322 is engaged in the control groove 314.

[0045] More specifically, the width of the control groove 314 is consistent with the diameter of the drive gear 322, and one side of the control groove 314 is provided with a tooth profile, when the drive gear 322 is in the control groove 314, the drive gear 322 is engaged with the tooth profile, and the output end of the control motor 321 has a bidirectional rotation function, which can control the adjusting rod 313 to drive the support assembly 4 to move left and right above the crawler conveyor 21 during operation, so that the upper jaw assembly 5 adjusts the clamped interrupter and insulating support to the corresponding mounting position.

[0046] Further, the support assembly 4 is composed of a first support rod 41, a mounting rod 42 and a second support rod 43, the two ends of the mounting rod 42 are respectively fixed on the opposite ends of the first support rod 41 and the second support rod 43, and the other end of the first support rod 41 is fixed on the front end of the adjusting rod 313.

[0047] The two sets of jaw assemblies 5 are movably connected on the first support rod 41 and the second support rod 43.

[0048] More specifically, after the first support rod 41, the mounting rod 42 and the second support rod 43 are fixed, they are in a straight line parallel to the top of the crawler conveyor 21, the jaw assembly 5 on the first support rod 41 is used to clamp the interrupter, and the jaw assembly 5 on the second support rod 43 is used to clamp the insulating support.

[0049] Further, the two sets of clamping jaw assemblies 5 each include a sleeve 51 movably sleeved on the side of the corresponding first support rod 41 and second support rod 43, a connecting arm 52 is fixed on the bottom of the sleeve 51, an installation cylinder 53 is fixed on the bottom end of the connecting arm 52, a clamping mechanism 54 is arranged on the front end of the installation cylinder 53, and a control mechanism 55 for controlling the opening and closing movement of the clamping mechanism 54 is arranged on the tail end of the installation cylinder 53.

[0050] The side of the mounting rod 42 is fixed with a double-acting cylinder 421, and the two output ends of the double-acting cylinder 421 are respectively fixed on the sleeves 51 of the two sets of clamping jaw assemblies 5.

[0051] More specifically, the output ends of the double-acting cylinder 421 at both ends operate synchronously, so that the two sets of clamping jaw assemblies 5 simultaneously displace in opposite directions or opposite directions, thereby adjusting the distance between the clamped arc-extinguishing chamber and the insulating support.

[0052] During displacement, the sleeve 51 slides on the side of the corresponding support rod, thereby driving the clamping mechanism 54 and the control mechanism 55 installed on both ends of the installation cylinder 53 to move simultaneously through the connecting arm 52.

[0053] It should be further explained that the sides of the first support rod 41 and the second support rod 43 are shaped (such as quadrilateral, pentagonal or hexagonal), and the sleeve 51 is matched with the shape of the side of the corresponding support rod, so that the sleeve 51 can slide smoothly on the side of the support rod, and at the same time, the sleeve 51 is limited to drive the clamping jaw assembly 5 as a whole to swing.

[0054] Further, the clamping mechanism 54 includes a slide rail plate 541 horizontally fixed on the front end of the installation cylinder 53, an adjusting slide groove 542 is formed on both ends of the slide rail plate 541, an adjusting slide rod 543 is slidably connected in the adjusting slide groove 542, and a curved knife jaw 544 is fixed on the side of the adjusting slide rod 543.

[0055] More specifically, the two ends of the adjusting slide rod 543 in the adjusting slide groove 542 at both ends of the slide rail plate 541 are each provided with a curved knife jaw 544, and when the adjusting slide rods 543 in the two adjusting slide grooves 542 simultaneously move towards each other, the two curved knife jaws 544 at both ends are closed or separated, and when closed, the curved knife jaws 544 are clamped on the side of the arc-extinguishing chamber or the insulating support.

[0056] It should be further explained that the circular groove presented by the curved knife jaw 544 of one set of clamping jaw assemblies 5 after being closed is matched with the diameter of the required installed arc-extinguishing chamber, and the circular groove presented by the curved knife jaw 544 of the other set of clamping jaw assemblies 5 after being closed is matched with the diameter of the side of the insulating support.

[0057] Further, the control mechanism 55 comprises an adjusting cylinder 551 fixed in the mounting cylinder 53, the output end of the adjusting cylinder 551 penetrates through the tail end of the mounting cylinder 53, and a cross rod 552 is fixed thereon, a plurality of connecting knobs 553 are arranged on the cross rod 552, a linkage rod 554 is rotatably connected to the side of the connecting knob 553, and a sleeve ring 555 is fixed at the front end of the linkage rod 554 and rotatably connected to the side of the adjusting slide rod 543.

[0058] More specifically, when the output end of the adjusting cylinder 551 extends outward, the linkage rod 554 is pulled through the cross rod 552, so that the linkage rod 554 rotates at the side of the connecting knob 553 while pulling the adjusting slide rods 543 at both ends of the slide rail plate 541 to displace in opposite directions, so that the curved blade claws 544 at both ends are closed to clamp and fix the arc-extinguishing chamber or the insulating support, and when the output end of the adjusting cylinder 551 is retracted inward, the structure moves reversely to separate the curved blade claws 544 at both ends to separate from the installed arc-extinguishing chamber or insulating support.

[0059] Further, the clamp jaw assembly 5 further comprises a driving mechanism 56 for driving the vacuum arc-extinguishing chamber to rotate, the driving mechanism 56 comprises a driving motor 561 fixed on the connecting arm 52, and a bevel gear one 562 is fixed on the output end of the driving motor 561.

[0060] The driving mechanism 56 further comprises a driving wheel 563 rotatably connected in the slide rail plate 541, a square tube 564 movably sleeved on the axis line of the driving wheel 563, a bevel gear two 565 fixed at one end of the square tube 564, and the bevel gear one 562 is engaged with the bevel gear two 565.

[0061] The side of the square tube 564 movably sleeved with a spring rod 566, and the both ends of the spring rod 566 are attached between the bevel gear two 565 and the slide rail plate 541.

[0062] More specifically, the output end of the driving motor 561 has a bidirectional rotation function, when the driving motor 561 operates, the output end drives the bevel gear one 562 to rotate, and through the tooth profile engagement force, the bevel gear two 565 drives the square tube 564 to rotate, so as to realize the rotation of the driving wheel 563, so that when the driving wheel 563 is attached to the side of the corresponding arc-extinguishing chamber or insulating support, the arc-extinguishing chamber or insulating support is driven to rotate, so that the bottom thereof is screwed on the corresponding mounting position of the shell.

[0063] Further, the correction assembly 6 comprises a tooth ring 61 movably sleeved on the side of the mounting rod 42, a right-angle plate 62 is fixed at the bottom of the tooth ring 61, and a correction mechanism 63 is movably connected on the right-angle plate 62.

[0064] The correction mechanism 63 comprises a telescopic rod 631 movably sleeved at the bottom end of the right-angle plate 62, a contact bead 632 fixed at the top end of the telescopic rod 631, and a transmission rod 633 fixed at the bottom end of the telescopic rod 631, one end of the transmission rod 633 being located above the bevel gear two 565.

[0065] More specifically, the right-angle plate 62 is L-shaped, and a hole with the same diameter as the telescopic rod 631 is formed in the plane at the bottom end of the right-angle plate 62, ensuring the stability of the vertical movement of the telescopic rod 631, and the transmission rod 633 is G-shaped, with the top end being horizontally extended and located above the bevel gear two 565, and the bottom end being fixed at the bottom of the telescopic rod 631. When the bottom end of the arc-extinguishing chamber is moved downward by being screwed onto the mounting position above the shell, and the bottom of the current transformer on the side of the arc-extinguishing chamber is attached to the contact bead 632 and presses the contact bead 632 downward to the bottom end along with the arc surface of the current transformer, the bevel gear two 565 is separated from the bevel gear one 562 by the transmission rod 633, so that the driving wheel 563 stops rotating, and at this time the connector of the current transformer is opposite to the insulating support, thereby ensuring that the isolation knife seat can be accurately connected to the interface of the current transformer.

[0066] Further, the top end of the telescopic rod 631 is fixed with a limiting ring 634, and a tension spring 635 is fixed between the limiting ring 634 and the opposite surface of the right-angle plate 62, the tension spring 635 being movably sleeved at the side of the telescopic rod 631.

[0067] More specifically, when the top end of the contact bead 632 is not stressed, the contact bead 632 and the transmission rod 633 are reset by the expansion pushing force of the tension spring 635.

[0068] It should be further noted that when resetting, the contact bead 632 does not contact the bottom of the current transformer, and the transmission rod 633 is above the bevel gear two 565 but does not contact it.

[0069] Further, the mounting rod 42 is fixed with an adjusting motor 422, and a toothed roller 423 is fixed at the output end of the adjusting motor 422, the toothed roller 423 being engaged with the inner side of the tooth ring 61.

[0070] More specifically, the adjusting motor 422 has the function of bidirectional rotation, and when operating, the output end drives the toothed roller 423 to rotate, and through the engagement force of the toothed roller 423 and the tooth ring 61, the overturning movement of the correction assembly 6 is realized.

[0071] It needs to be further explained that the multi-link mechanical arm 3 drives the support assembly 4 to rotate in the opposite direction to separate from the crawler conveyor 21, and when clamping the arc-extinguishing chamber and the insulating support for feeding, the correcting assembly 6 is in the opposite direction of the clamping jaw assembly 5, and before assembling the arc-extinguishing chamber and the insulating support with the shell, the motor 422 is adjusted to operate, so that the correcting assembly 6 and the clamping jaw assembly 5 are in the same direction and are aligned, and the joint angle of the side current transformer during the installation of the arc-extinguishing chamber is calibrated.
