[0028] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0029] The present utility model provides a welding machine for a contact system to solve the problems in the prior art that the bus bar and multiple contact pieces in the circuit breaker contacts are welded one by one manually, the welding efficiency is not high, and at the same time, the temperature control during welding is not good, which easily causes deformation of the bus bar.
[0030] For the convenience of understanding, the specific process in the embodiments of this application will be described below. Please refer to Figure 1 , Figure 2 and Figure 7 , a welding machine for a contact system in the embodiments of this application includes a clamping station 2, a sliding guide rail 3, a conveyor module 4, a welding station 5 and a water spraying device 6 arranged in a frame 1; the sliding guide rail 3 runs through the clamping station 2; two conveyor modules 4 are symmetrically arranged on the sliding guide rail in a slidable manner and are respectively located on both sides of the clamping station, and are respectively used to convey the bus bar 10 to the clamping station and collect the welded bus bar from the clamping station; the welding station 5 is arranged above the clamping station 2, wherein the clamping station 2 is used to clamp the bus bar sent to the clamping station 2 by the conveyor module 4, and then the welding station 5 welds the bus bar 10 and the contact piece 11; the water spraying device 6 is arranged on the welding station 2 and is used to spray water to the welding area for cooling.
[0031] For the welding machine of the contact system of the present utility model, first, the contact piece 81 is inserted into the insertion part of the bus bar 80, and then the bus bar 80 with the contact piece 81 inserted is sent to the clamping station 2 by the conveying module 4 on the left side for clamping. After clamping, the contact piece 81 is welded to the bus bar 80 by the welding station, thus automatically completing the welding of the contact piece 81 and the bus bar 80. At the same time, during the welding process, the bus bar 80 is cooled by the water spraying device 6 to ensure that the welded product does not deform and has a high qualified rate.
[0032] As a preferred embodiment, based on Figures 4 to 5 , the clamping station 2 includes an active clamping block 20 and a driven clamping block 21 which are oppositely arranged on both sides of the sliding guide rail 3; the active clamping block 20 can be driven by a clamping cylinder 22 to clamp with the driven clamping block 21 before and after. During operation, when the bus bar 80 is conveyed into the clamping station 2 by the conveying module 4, at this time, the clamping cylinder 22 drives the active clamping block 20 to move towards the side of the driven clamping block 21, thereby clamping the bus bar 80, which is convenient for the subsequent welding station 5 to weld the bus bar 80 and the contact piece 81.
[0033] In addition, a temperature sensor 23 for detecting the temperature at the welding joint of the bus bar 80 and the contact piece 81 is further provided on one side of the active clamping block 20, so that the temperature of the welded product can be understood in real time to avoid deformation caused by too high product temperature.
[0034] As a preferred embodiment, based on Figure 2 and Figure 3 , specifically, the conveying module 4 includes a sliding bracket 41 slidably arranged on the sliding guide rail 3 by a pushing cylinder 40; an L-shaped limiting strip 42 for positioning the product is provided on the sliding bracket.
[0035] This embodiment includes two symmetrically arranged conveying modules 4. When it is necessary to send the bus bar 80 to the clamping station 2, the pushing cylinder 40 pushes the sliding bracket 41 to slide on the sliding guide rail 3 until the bus bar 80 is located between the active clamping block and the driven clamping block. Then, the active clamping block is pushed by the clamping cylinder to cooperate with the driven clamping block to clamp the bus bar 80. At this time, the corresponding conveying module 4 on the left side returns to its original position; when the product welding is completed, the conveying module on the right side starts to work. The conveying module moves to the left below the bus bar 80, and then the active clamping block retracts. The bus bar 80 welded with the contact piece 81 automatically falls onto the conveying module on the right side. Finally, the conveying module 4 on the right side transfers the welded bus bar 80 out.
[0036] Among them, a position sensor 43 for detecting whether the bus bar is in place is further provided on one side of the sliding guide rail 3 at the initial positions of the two conveying modules 4, so as to judge whether the bus bar 80 is in the position to be placed in the conveying module.
[0037] As a preferred embodiment, based on Figures 4 to 6 , in this embodiment, the water spraying device 6 includes a water outlet pipe 51 and a water outlet channel 52 provided at the front end and the rear end of the welding head 50 in the welding station 5; the water outlet pipe 51 and the water outlet channel 52 are respectively communicated with an external water source; a plurality of linearly distributed water outlet holes 53 are provided on the lower surface of the water outlet pipe 51; two water outlet ports 54 are provided at the bottom of the water outlet channel 52.
[0038] During operation, when the bus bar becomes too hot due to welding, the external water source flows into the water outlet pipe 51 and the water outlet channel 52 respectively, and then flows out through the plurality of water outlet holes 53 and the two water outlet ports 54, so that the bus bar can be quickly cooled down to avoid damage caused by excessive temperature of the bus bar.
[0039] As a preferred embodiment, based on Figures 1 to 2 , the front and rear ends of the clamping station 2 are sealed by two sealing plates 70, and the left and right ends of the clamping station 2 are sealed by lifting plates 71; the lifting plates 71 are arranged at the left and right ends of the clamping station in a liftable manner through lifting cylinders 72, so as to ensure that the product is in a sealed space during welding.
[0040] When the left conveying module 4 drives the product to move to the right, at this time, the left lifting plate 71 moves upward under the drive of the lifting cylinder 72, so that the left conveying module 4 drives the product to move into the clamping station 2; when the bus bar 80 and the contact piece 81 are welded, at this time, the right lifting plate 71 moves upward under the drive of the corresponding lifting cylinder 72, so that the right conveying module 4 can convey the bus bar 80 out of the clamping station 2.
[0041] During actual operation, first insert the contact piece into the socket of the bus bar, and at the same time, the position of the bus bar is limited by the L-shaped limit block in the left conveying module.
[0042] Turn on the equipment, the position sensor on the left senses that the bus bar is in the conveying module 4, and the conveying module moves to the right. When it moves to the clamping station, the left conveying module stops working.
[0043] The clamping station 2 clamps the bus bar 10, the left conveying module 4 returns to its original position, and then the welding head 50 first moves down to the set position, and then the water spraying device 6 pre-sprays water to cool the welding part and the edge of the bus bar and the contact piece.
[0044] The welding head moves down to the welding place of the bus bar and the contact piece to weld the bus bar and the contact piece. After welding is completed, the welding head returns to its original position, and the water spraying device immediately starts spraying water to quickly cool the bus bar with the welded contact piece.
[0045] After cooling down, the conveying module 4 on the right moves to the left to the lower part of the busbar of the welding contact piece, the clamping station 2 is released, and then the conveying module 4 on the right moves the welded busbar out.
[0046] The welding machine for this contact system completes the whole processing process automatically, with high welding efficiency. At the same time, the busbar with the welded contact piece will not be damaged due to excessive temperature.
[0047] As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
