[0072] In some embodiments of the present application, an automatic welding device is provided, which is at least used to spot weld a first workpiece 1 and a second workpiece 2 into one.

[0073] In some embodiments of the present application, reference Figures 1 to 3 The first workpiece 1 and the second workpiece 2 shown in the figure are: the first workpiece 1 is a rectangular shell-shaped sheet metal part, whose bottom and rear are open, and the second workpiece 2 is a U-shaped shell-shaped sheet metal part, spot welded on the inner wall of a vertical side panel b of the first workpiece 1, and extending in the horizontal direction. After spot welding, the first workpiece 1 and the second workpiece 2 are a drawer-shaped product as a whole, and the second workpiece 2 constitutes the internal guide rail of the entire drawer-shaped product.

[0074] Of course, the first workpiece 1 and the second workpiece 2 may also be in other shapes, and there is no specific limitation on this.

[0075] In some embodiments of the present application, reference 4 to Fig.14 The automatic welding equipment includes a control unit (not shown), a cabinet 100, a first positioning assembly, a second positioning assembly, a first electrode moving device 400, a second electrode moving device 500 and a power supply 600.

[0076] The cabinet 100 is the cabinet of the entire automatic welding equipment and can be used as the installation base for the relevant structural components of the equipment. Figure 1 The cabinet 100 shown in the figure takes a rectangular cabinet as an example, and a plurality of strip-shaped support bases 700 are provided at the bottom thereof. The support bases 700 can be fixed on the ground by screws.

[0077] The cabinet 100 has a support table 110, i.e., its top surface. The support table 110 is horizontal so as to install relevant structural components that need to be exposed. The cabinet 100 is hollow inside to provide installation space so that some structural components that do not need to be exposed, such as a power supply 600 and a control unit, can be arranged inside the cabinet to simplify the structure of the whole machine and make the structure more compact. The cabinet 100 is equipped with a cabinet door 120 so as to repair or maintain the structural components inside the cabinet.

[0078] The first positioning assembly is disposed on the supporting table 110 and is used to position and support the first workpiece 1 so that the first workpiece 1 is accurately placed. When the first workpiece 1 is positioned by the first positioning assembly, it is in the spot welding position, avoiding repeated positioning adjustments.

[0079] The second positioning assembly is disposed on the supporting table 110 and is used to position and support the second workpiece 2 so that the second workpiece 2 is accurately placed.

[0080] In some embodiments of the present application, Figure 4 , Figure 5 As shown, the first workpiece 1 is placed upside down, that is, positioned on the first positioning assembly with the opening facing downward, and the second positioning assembly is located on the inner side of the first workpiece 1 so as to position the second workpiece 2 located inside the first workpiece 1 .

[0081] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the first positioning assembly includes a plurality of positioning blocks 200 arranged at intervals along the circumference of the first workpiece 1. The positioning blocks 200 are fixed on the mounting base plate 590 described below, and the mounting base plate 590 is fixed on the support table 110 by screws. An open positioning groove 210 is formed at the top of the positioning block 200, and the bottom edge of the circumferential side plate of the first workpiece 1 is embedded in the positioning groove 210 to achieve positioning.

[0082] The first electrode moving device 400 is located on one side of the first workpiece 1, specifically on one side of the vertical side plate b where the second workpiece 2 is located after welding, and includes a first reciprocating linear motion mechanism and a first electrode 410. The first reciprocating linear motion mechanism is configured to drive the first electrode 410 to move toward or away from the first workpiece 1.

[0083] The second electrode moving device 500 is located on the other side of the first workpiece 1, that is, the other side opposite to the side where the first electrode moving device 400 is located, and includes a second reciprocating linear motion mechanism and a second electrode 510. The second reciprocating linear motion mechanism is configured to drive the second electrode 510 to move toward or away from the first workpiece 1.

[0084] The power source 600 is used to at least supply power to the first electrode 410 and the second electrode 510 so that the first electrode 410 and the second electrode 510 discharge to achieve spot welding.

[0085] In the welding state, the first electrode 410 is pressed on one side of the first workpiece 1 (specifically, the outer wall of the vertical side plate b), and the second electrode 510 presses the second workpiece 2 on the other opposite side of the first workpiece 1 (specifically, the inner wall of the vertical side plate b) to spot weld the first workpiece 1 and the second workpiece 2 into one.

[0086] The automatic welding equipment in the embodiment of the present application respectively positions the first workpiece 1 and the second workpiece 2 to be spot-welded by the first positioning component and the second positioning component to ensure the accuracy of the welding position, and realizes automatic pressure spot welding and separation of the first electrode 410 and the second electrode 510 by the first electrode moving device 400 and the second electrode moving device 500, and the second electrode 510 can press the second workpiece 2 onto the first workpiece 1, realizing the automatic spot welding of multiple workpieces into one. Compared with the existing manual single spot welding, the welding quality and production efficiency are greatly improved, and the production cost and the labor intensity of workers are reduced.

[0087] In some embodiments of the present application, Figure 4 and Figure 7 As shown, the automatic welding equipment also includes a clamping device 800 for clamping the first workpiece 1 so that the first workpiece 1 can remain stationary during spot welding and will not move or be misplaced due to the pressure of the first electrode 410, thereby further ensuring the welding quality.

[0088] The clamping device 800 includes a clamping drive component 810 and a clamping component 820 arranged on the output end of the clamping drive component 810. The clamping drive component 810 drives the clamping component 820 to move toward or away from the first workpiece 1 to fix the first workpiece 1 in a welding state and release the first workpiece 1 in a non-welding state.

[0089] In some embodiments of the present application, the movement direction of the first electrode 410 and the second electrode 510 is horizontal, and the first electrode 410 and the second electrode 510 are facing each other. During spot welding, horizontal pressure is applied to the first workpiece 1 and the second workpiece 2. The direction of the pressure exerted by the first electrode 410 on the first workpiece 1 is opposite to the direction of the pressure exerted by the second electrode 510 on the second workpiece 2, so that the first workpiece 1 and the second workpiece 2 are pressed against each other.

[0090] Correspondingly, the clamping device 800 is located above the support table 110, and performs vertical lifting and lowering motion above the first workpiece 1 to fix or release the first workpiece 1. Specifically, the clamping device 800 descends to abut against the top plate of the first workpiece 1 to apply downward pressure to the first workpiece 1 to achieve clamping and fixing; when the clamping device 800 rises, it disengages from the first workpiece 1 to facilitate workpiece removal or other operations. The clamping device 800 presses down on the first workpiece 1 to position the first workpiece 1 firmly, and will not interfere with the movement of the first electrode 410 and the second electrode 510, so that the force on the first workpiece 1 is more uniform, thereby ensuring the positioning reliability of the first workpiece 1.

[0091] In some embodiments of the present application, a clamping device support component 900 is extended upward from the support table 110, and the clamping device support component 900 has a horizontal support portion 910. The clamping device 800 is arranged on the horizontal support portion 910 to raise the position of the clamping device 800 to facilitate vertical lifting from above the first workpiece 1.

[0092] The pressing driving component 810 is a lifting driving component, and the pressing component 820 includes an insulating pressing portion 821 for contacting and abutting against the first workpiece 1 to fix the first workpiece 1 in a welding state.

[0093] The clamping drive component 810 can be a structural component that can realize linear lifting motion, such as an air cylinder or an oil cylinder or an electric lead screw slider structure, and the pressure is transmitted to the first workpiece 1 through the clamping component 820. Taking the air cylinder as an example, it is placed upside down, the outer end of the piston rod is its telescopic output end, the cylinder body is fixed on the horizontal support part 910, and the piston rod passes through the horizontal support part 910 and extends downward.

[0094] The clamping component 820 includes an insulating clamping portion 821, which is in direct contact and abutment with the first workpiece 1. Since the first electrode 410 and the second electrode 510 need to discharge during spot welding, the clamping component 820 needs to maintain contact and clamping with the first workpiece 1. The insulating clamping portion 821 made of insulating material can avoid electrical conduction and burning of the product.

[0095] The insulating pressing part 821 can be made of a plastic plate, such as POM, which is horizontally arranged and has a large area, so as to have a large contact area with the first workpiece 1, and can also avoid crushing the first workpiece 1 as much as possible while providing insulation. The insulating pressing part 821 can also be made of a rubber plate or other insulating materials, which is not specifically limited here.

[0096] Since the insulating clamping part 821 made of plastic or rubber material has poor strength, it may sag and deform under gravity after long-term use. In order to ensure the structural strength of the clamping part 820 and make the clamping effect reliable, in some embodiments of the present application, the clamping part 820 also includes a rigid connecting plate 822, such as a metal plate, which serves as an intermediate connector between the output end of the lifting drive component and the insulating clamping part 821. The rigid connecting plate 822 is attached to the insulating clamping part 821 and is fixedly connected to the insulating clamping part 821 at multiple locations at the periphery, thereby improving the structural strength of the entire clamping part 820. The area of ​​the rigid connecting plate 822 is smaller than that of the insulating clamping part 821, and it will not contact the first workpiece 1 when clamping the first workpiece 1, thereby ensuring the insulation clamping of the clamping part 820 and the first workpiece 1.

[0097] In order to make the clamping device 800 work reliably and run smoothly, the clamping device 800 also includes a lifting guide mechanism 830 to guide the lifting action of the piston rod. The lifting guide mechanism 830 can be a guide column guide sleeve mechanism, a guide rail slider mechanism, etc., and can be symmetrically arranged at two opposite sides of the piston rod.

[0098] For the second electrode moving device 500, Figure 8 , Fig. 9 , Figures 11 to 13 As shown, it is arranged on the supporting table 110, and the second reciprocating linear motion mechanism includes a second driving component 520 and a second connecting component 530 arranged on the output end of the second driving component 520; the second electrode 510 is arranged on the second connecting component 530, and the second workpiece 2 is arranged on the second connecting component 530 before welding, and is in contact with the discharge surface 511 of the second electrode 510, and is separated from the second connecting component 530 after welding.

[0099] The second driving component 520 can be a cylinder, an oil cylinder, or an electric lead screw slider structure that can achieve linear reciprocating motion, and can drive the second electrode 510 to achieve linear reciprocating motion through the second connecting component 530. Figure 8 and Fig. 9 Taking the horizontal direction of movement of the first electrode 410 and the second electrode 510 as an example, the second driving component 520 is placed horizontally, perpendicular to the vertical side plate b of the first workpiece 1 where the second workpiece 2 is located after welding, the outer end of the piston rod is its telescopic output end, the cylinder body is fixed on the supporting table 110, the second connecting component 530 is fixedly connected to the outer end of the piston rod, the second electrode 510 and the second workpiece 2 before welding are both arranged on the second connecting component 530, the second electrode 510 and the second connecting component 530 are fixedly connected, the second workpiece 2 and the second connecting component 530 are movably connected, and are located between the first workpiece 1 and the second electrode 510, so that the second electrode 510 can press the second workpiece 2 on the first workpiece 1, and after the second workpiece 2 and the first workpiece 1 are spot welded into one, when the piston rod is pulled out, the second workpiece 2 smoothly detaches from the second connecting component 530.

[0100] By using the second electrode moving device 500, the second workpiece 2 can be synchronously moved with the second electrode 510. The second electrode 510 can synchronously deliver the second workpiece 2 to the spot welding position while moving normally, so as to fit against the first workpiece 1 to achieve spot welding. Compared with the manual operation in the prior art to keep the second workpiece 2 in contact with the first workpiece 1, it is only necessary to place the second workpiece 2 on the second connecting component 530 of the second electrode moving device 500 before placing the first workpiece 1. In the subsequent welding process, the second workpiece 2 is driven by the second electrode 510 to move, which is convenient for operation and is conducive to improving welding efficiency and welding quality.

[0101] The second workpiece 2 is arranged together with the second electrode 510 on the second connecting component 530. When it drives the second workpiece 2 to move to the spot welding position, the pressure of the second electrode 510 is not likely to cause the second workpiece 2 to shift, which is also beneficial to ensuring the welding quality.

[0102] The second positioning component can be arranged on the second connecting member 530 and then indirectly arranged on the support table 110, or directly arranged on the support table 110, or partly arranged on the second connecting member 530 and partly arranged directly on the support table 110. The second positioning component can be in the form of a positioning block 300, which is arranged at each end of the second workpiece 2 to position it in the front and rear directions, such as Fig.11 The second workpiece 2 can be limited in the up and down directions by providing relevant positioning structures on the second connecting member 530, such as positioning grooves, positioning protrusions, etc.

[0103] Taking the U-shaped shell-shaped second workpiece 2 as an example, the second connecting member 530 has a protrusion 533 that matches the U-shaped profile of the second workpiece 2. The second workpiece 2 is positioned in the up and down directions by facing its U-shaped opening toward the second connecting member 530 and buckling on the protrusion 533 of the second connecting member 530. Figures 11 to 13 As shown, the second workpiece 2 is attached to the discharge surface 511 of the second electrode 510 by its bottom plate.

[0104] To facilitate the connection between the second electrode 510 and the power source 600, in some embodiments of the present application, the second connecting component 530 includes a conductive mounting portion 534, which is used for conductive connection with the power source 600, the second electrode 510 is fixed on the conductive mounting portion 534 and in conductive contact with the conductive mounting portion 534, and the second workpiece 2 to be welded is snap-fitted and clamped on the conductive mounting portion 534, that is, the protrusion 533 is formed on the conductive mounting portion 534. Then, the entire second connecting component 530 does not need to be set to a conductive material, which is conducive to reducing costs and ensuring safety in use.

[0105] The conductive mounting portion 534 may be a conductive metal block structure, which may be conductively connected to the power source 600 via a conductive copper sheet 540 .

[0106] In some embodiments of the present application, Fig.11 As shown, an insulating component 550 is sandwiched between the contact surface of the second workpiece 2 and the conductive mounting portion 534 to achieve insulation between the second workpiece 2 and the conductive mounting portion 534. In this way, during discharge, the heated surface of the second workpiece 2 is only the contact surface with the second electrode 510, ensuring heat concentration and improving spot welding quality.

[0107] In some embodiments of the present application, Figures 11 to 13As shown, a mounting positioning groove 535 is formed on the conductive mounting portion 534, and the mounting positioning groove 535 is adapted to the shape of the second electrode 510. The second electrode 510 is embedded in the mounting positioning groove 535, and the discharge surface 511 of the second electrode 510 protrudes from the outside of the mounting positioning groove 535 to fit against the second workpiece 2. The mounting positioning groove 535 plays a positioning role in the installation of the second electrode 510 on the conductive mounting portion 534, improves the installation or replacement efficiency of the second electrode 510, and makes the whole machine more convenient to use. The second electrode 510 can be fixedly connected to the conductive mounting portion 534 by screws.

[0108] In some embodiments of the present application, the second electrode movement device 500 also includes a guide component for guiding the linear movement of the second electrode 510, so that the synchronous movement of the second electrode 510 and the second workpiece 2 is smoother and more reliable, and the position of the second workpiece 2 is more accurate.

[0109] The guide assembly specifically includes a guide portion provided on the second connecting member 530 and a guide structure provided on the support table 110, and the guide structure cooperates with the guide portion for linear guidance. Figures 11 to 13 As shown, the guide portion is a guide slider 560 , and the guide structure is a guide rail 570 . The guide rail 570 can be set on the support table 110 by being fixed on the guide rail pad 580 , and the guide rail pad 580 is fixed on the support table 110 .

[0110] Of course, the guide assembly can also be in other structural forms, such as a guide column and guide sleeve mechanism, etc., and no specific limitation is made here.

[0111] In some embodiments of the present application, the guide assembly is provided at two locations, symmetrically disposed on opposite sides of the output end of the second driving component 520, so as to improve the guiding effect.

[0112] In some embodiments of the present application, the second electrode moving device 500 further includes a limiting component for assisting in limiting the movement range of the second electrode 510. Fig.11 and Fig.12 As shown, the limiting assembly includes a limiting long hole 531 provided on the second connecting member 530 and a limiting column 532 fixedly provided on the supporting table 110 . The length direction of the limiting long hole 531 is parallel to the moving direction of the second electrode 510 .

[0113] according to Fig.11 and Fig.12Taking the perspective shown as an example, when the second driving component 520 drives the second connecting component 530 to move to the left until the right end of the limiting long hole 531 abuts against the limiting column 532, the second electrode 510 reaches the extreme position of movement to the left, that is, it drives the second workpiece 2 to reach the spot welding position where it is in contact with the first workpiece 1. When the second driving component 520 drives the second connecting component 530 to move to the right until the left end of the limiting long hole 531 abuts against the limiting column 532, the second electrode 510 reaches the extreme position of movement to the right, and the second electrode 510 is completely separated from the first workpiece 1 and the second workpiece 2 that are spot welded as a whole.

[0114] By setting a limit assembly, the movement stroke of the second electrode 510 can be auxiliary limited, making its movement more reliable, and the cooperation between the limit column 532 and the limit long hole 531 can also play a guiding role, further improving the movement stability of the second electrode 510.

[0115] The top end of the limiting column 532 is fixedly connected with a supporting top plate 5120 , which is horizontally arranged and fits against the inner wall of the top plate of the first workpiece 1 to support the inner wall of the first workpiece 1 and prevent the first workpiece 1 from being deformed by the downward pressure of the pressing component 820 .

[0116] In some embodiments of the present application, Figure 8 , Fig. 9 , Figures 11 to 13 As shown, the second electrode movement device 500 also includes a mounting base plate 590, which is fixed on the support table 110, and a mounting positioning component 5100 is fixed on the mounting base plate 590. The mounting positioning component 5100 and the second connecting component 530 are respectively located on the opposite sides of the second driving component 520, and the mounting positioning component 5100 has a positioning surface 5101; the second driving component 520 is arranged on the mounting base plate 590, and is in contact with the positioning surface 5101 and is fixedly connected to the mounting positioning component 5100.

[0117] By providing the installation base plate 590, the second electrode moving device 500 can be formed into an integral module, which is convenient for overall disassembly and assembly, and improves the convenience of equipment installation. The installation positioning component 5100 can play a positioning role in the installation of the second driving component 520, improving the installation efficiency and installation position accuracy.

[0118] For the first electrode moving device 400, as Figures 7 to 9 As shown, it is arranged opposite to the second electrode moving device 500 , the first reciprocating linear motion mechanism includes a first driving component 420 and a first connecting component 430 arranged on the output end of the first driving component 420 , and the first electrode 410 is arranged on the first connecting component 430 .

[0119] The first driving component 420 can be a structural component that can realize linear reciprocating motion, such as an air cylinder or an oil cylinder or an electric lead screw slider structure, and drives the first electrode 410 to realize linear reciprocating motion through the first connecting component 430. The cylinder body of the first driving component 420 is fixed on the support table 110, the first connecting component 430 is fixed on the outer end of the piston rod, and the first electrode 410 is arranged on the first connecting component 430. The first electrode 410 and the second electrode 510 are arranged in the same direction and size, and are arranged relatively.

[0120] Also, to facilitate the connection between the first electrode 410 and the power supply 600, in some embodiments of the present application, the first connecting component 430 also includes a conductive mounting portion, which is used to conductively connect to the power supply 600. The first electrode 410 is fixed on the conductive mounting portion and is in conductive contact with the conductive mounting portion. Therefore, there is no need to set the entire first connecting component 430 to a conductive material, which is beneficial to reducing costs and ensuring safe use.

[0121] In some embodiments of the present application, the first workpiece 1 is spot welded to a plurality of second workpieces 2, that is, the first workpiece 1 is spot welded to a plurality of second workpieces 2 at different positions, and the first electrode movement device 400 is correspondingly provided at a plurality of positions, and the second electrode movement device 500 is correspondingly provided at a plurality of positions. It is possible to realize synchronous operation of a plurality of spot welding positions, and welding at the same time, reducing the labor intensity of clamping, turnover, and handling of operators, and improving welding efficiency and welding quality.

[0122] like Figure 2 As shown, if the second workpiece 2 is spot welded on the inner walls of the two opposite vertical side plates b adjacent to the vertical side plate a of the first workpiece 1, the first electrode movement device 400 is correspondingly set at two locations, and the second electrode movement device 500 is correspondingly set at two locations. The two first electrode movement devices 400 are symmetrically set, and the two second electrode movement devices 500 are symmetrically set, as shown in FIG. Figure 4 , Figure 7 and Figure 8 shown.

[0123] In some embodiments of the present application, the first workpiece 1 itself also has a portion c to be spot-welded, and the portion c to be spot-welded extends along the first direction. Figures 1 to 3 Taking the rectangular shell-shaped first workpiece 1 shown as an example, the part c to be spot welded is the adjacent part of its two adjacent vertical side panels a and b. Specifically, a bending flange d is formed on the vertical side edge of one of the two vertical side panels a, and the bending flange d is bent toward the inner side of the other vertical side panel b and fits on the inner wall of the vertical side panel b. The spot welding connection of the two vertical side panels a and b is achieved by spot welding the bending flange d with the vertical side panel b. The extension direction of the part c to be spot welded is the first direction, that is, the height direction of the first workpiece 1.

[0124] To achieve spot welding of the portion to be spot welded c, in some embodiments of the present application, as Figures 3 to 8 ,as well as Fig.14 As shown, the automatic welding equipment further includes an electrode A moving device 1000 and an electrode B moving device 1100 .

[0125] The electrode A moving device 1000 is located on one side of the portion c to be spot welded, and includes an electrode A driving component 1010 and an electrode A assembly 1020. The electrode A assembly 1020 includes an electrode A mounting component 1021 and a plurality of electrodes A 1022. The plurality of electrodes A 1022 are arranged on the electrode A mounting component 1021 at intervals along the second direction. The electrode A driving component 1010 drives the electrode A assembly 1020 to move toward or away from the portion c to be spot welded.

[0126] The electrode B moving device 1100 is located on the other side opposite to the part c to be spot welded, and includes an electrode B first driving component 1110, an electrode B second driving component 1120 and an electrode B1130. The electrode B first driving component 1110 drives the electrode B1130 to move along the third direction to each spot welding position respectively opposite to each electrode A1022. The electrode B second driving component 1120 drives the electrode B1130 to move toward or away from the part c to be spot welded after moving to the position along the third direction, so as to cooperate with the electrode A1022 to realize spot welding or resetting after spot welding.

[0127] The second direction and the third direction are parallel to the first direction. Figures 1 to 3 Taking the first workpiece 1 as an example, the first direction is the height direction of the first workpiece 1 , and the second direction and the third direction are both along the height direction of the first workpiece 1 .

[0128] The power source 600 also supplies power to the electrode A 1022 and the electrode B 1130 .

[0129] Taking the example that there are two electrodes A1022, which are arranged at intervals along the first direction, the first driving component 1110 of electrode B drives electrode B1130 to move along the second direction to a spot welding position opposite to the first electrode A1022, and then the second driving component 1120 of electrode B drives the electrode B1130 at this position to move in the direction toward the portion c to be spot welded, so as to cooperate with the first electrode A1022 to achieve spot welding; the second driving component 1120 of electrode B can also drive electrode B1130 to move to a spot welding position opposite to the second electrode A1022, and then the second driving component 1120 of electrode B drives the electrode B1130 at this position to move in the direction toward the portion c to be spot welded, so as to cooperate with the second electrode A1022 to achieve spot welding.

[0130] The cooperation between the electrode A moving device 1000 and the electrode B moving device 1100 can realize point-by-point automated welding of the workpiece to be spot-welded portion c having multiple welding spots. Compared with the existing manual single-spot welding, it can greatly improve the welding efficiency and welding quality, and reduce the production cost and the labor intensity of workers.

[0131] In some embodiments of the present application, the electrode A mounting component 1021 is made of a conductive material, and is conductively connected to the electrode A1022. The electrode A mounting component 1021 can be conductively connected to the power supply 600 through a conductive copper sheet. By arranging the electrode A1022 on the conductive electrode A mounting component 1021, the electrode A mounting component 1021 is conductively connected to the power supply 600, and it is possible to realize a unified connection between multiple electrodes A1022 and the power supply 600 on the basis of facilitating the installation of the electrode A1022, without the need for multiple electrodes A1022 to be respectively provided with conductive connectors to connect to the power supply 600, which is conducive to simplifying the conductive connection structure and making the structure simple and compact.

[0132] The electrode A mounting component 1021 may be a conductive metal block structure, which may be conductively connected to the power source 600 via a conductive copper sheet 540 .

[0133] In some embodiments of the present application, the electrode A driving component 1010 is a telescopic driving component, and its telescopic direction is perpendicular to the first direction. The electrode A mounting component 1021 is connected to the telescopic output end of the electrode A driving component 1010 through an insulating connector 1040. Figures 1 to 3 Taking the first workpiece 1 as an example, the extension direction of the electrode A driving component 1010 is horizontal, perpendicular to the portion c to be spot welded.

[0134] An insulating connector 1040 is provided between the electrode A mounting component 1021 and the telescopic output end of the electrode A driving component 1010 to achieve insulation between the electrode A mounting component 1021 and the electrode A driving component 1010, thereby preventing the electrode A driving component 1010 from burning out.

[0135] The electrode A driving component 1010 can be a structural component that can achieve linear reciprocating motion, such as an air cylinder, an oil cylinder, or an electric lead screw slider structure, and the electrode A 1022 can be driven to achieve linear reciprocating motion through the electrode A mounting component 1021.

[0136] In some embodiments of the present application, Fig.14 As shown, the electrode A driving component 1010 is a cylinder, and its telescopic output end includes a cylinder piston 1011 and a first sliding guide assembly. One end of the sliding member in the first sliding guide assembly is connected to the cylinder piston 1011, and the other end is connected to the insulating connector 1040.

[0137] The first sliding guide assembly specifically includes a fixed slider 1012 arranged on a first cylinder fixing frame 1030 and a sliding guide rail 1013 connected to the piston rod of the electrode A driving component 1010. The sliding guide rail 1013 is connected to the insulating connector 1040. When the piston rod is extended or retracted, the insulating connector 1040, the electrode A mounting component 1021 and the electrode A1022 are driven to extend or retract together through the sliding guide rail 1013. The sliding guide rail 1013 cooperates with the fixed slider 1012 for guiding, thereby improving the movement stability and position accuracy of the electrode A1022 and improving the welding quality.

[0138] The first cylinder fixing frame 1030 is fixed on the supporting table 110 by screws, and the electrode A driving component 1010 can be specifically fixed on the first cylinder fixing frame 1030 .

[0139] The first sliding guide assembly may also be in other structural forms, such as a guide column and guide sleeve structure.

[0140] In some embodiments of the present application, the second driving component 1120 of the electrode B is a telescopic driving component, and its telescopic direction is perpendicular to the first direction. Fig.14 Taking the viewing angle shown as an example, the telescopic direction of the second driving component 1120 of electrode B is horizontal, and electrode B1130 is connected to the telescopic output end of the second driving component 1120 of electrode B.

[0141] The first driving component 1110 of the electrode B is a telescopic driving component, and its telescopic direction is parallel to the first direction. Fig.14 Taking the perspective shown as an example, the telescopic direction of the first driving component 1110 of electrode B is the vertical direction, and the second driving component 1120 of electrode B is connected to the telescopic output end of the first driving component 1110 of electrode B. When the first driving component 1110 of electrode B is working, it can drive the second driving component 1120 of electrode B and the electrode B 1130 to telescopically move as a whole along a third direction parallel to the first direction.

[0142] In some embodiments of the present application, the relative arrangement positions of the electrode A driving component 1010, the electrode B second driving component 1120, and the electrode B second driving component 1120 are as follows: Figures 7 to 9 , Fig.14 As shown, the movement direction of electrode A 1022 and electrode B 1130 is horizontal.

[0143] In some embodiments of the present application, Fig.14As shown, the telescopic output end of the first driving component 1110 of the electrode B is fixedly connected with the adapter component 1140, the second driving component 1120 of the electrode B is arranged on the adapter component 1140, and the adapter component 1140 is also provided with a hinged connection part 1150 arranged in an interval with the second driving component 1120 of the electrode B, and the arrangement direction of the hinged connection part 1150 and the second driving component 1120 of the electrode B is parallel to the first direction, so as to Fig.14 Taking the perspective shown as an example, the hinged connection portion 1150 and the second driving component 1120 of electrode B are arranged at intervals in the vertical direction.

[0144] Electrode B1130 includes an electrode B mounting component 1131 and an electrode B body 1132. The electrode B mounting component 1131 is hinged to the telescopic output end of the electrode B second driving component 1120 and the hinged connection part 1150, and the electrode B body 1132 is arranged on the electrode B1130 mounting part.

[0145] like Fig.14 As shown, the electrode B mounting component 1131 extends vertically, and its bottom end is hinged to the telescopic output end of the second driving component 1120 of electrode B, and is hinged to the hinged connection part 1150 at approximately the middle position; when the first driving component 1110 of electrode B drives electrode B1130 to move to face the first electrode A1022 (the electrode A1022 at the lower middle of the two electrodes A1022), the second driving component 1120 of electrode B extends, so that the electrode B mounting component 1131 rotates counterclockwise with its hinge point with the hinged connection part 1150 as a fulcrum, so that the electrode B body 1132 moves toward the side of the first electrode A1022, that is, the side where the part c to be spot welded is located. At this time, the first electrode A1022 also moves synchronously to the side where the part c to be spot welded is located, and the first electrode A1022 and the electrode B body 1132 cooperate to spot weld this welding point of the part c to be spot welded.

[0146] After this spot welding is completed, the two electrodes A1022 are reset, and the electrode B1130 is reset. The first driving component 1110 of electrode B continues to drive electrode B1130 to move upward until it is opposite to the second electrode A1022 (the upper electrode A1022 between the two electrodes A1022), and the above spot welding process is repeated.

[0147] When the electrode B body 1132 is far away from the electrode B second driving component 1120 due to installation space limitation or other reasons, the vertical dimensions of the adapter component 1140 and the electrode B installation component 1131 will be relatively large, resulting in unstable lifting movement. To solve this problem, the electrode B movement device 1100 also includes a second sliding guide assembly, whose guiding direction is parallel to the extension direction of the electrode B first driving component 1110, and the adapter component 1140 is also connected to the sliding member in the second sliding guide assembly.

[0148] The second sliding guide assembly specifically includes a fixed guide rail 1170 provided on a second cylinder fixing frame 1160 and a sliding block 1180 connected to the adapter component 1140. In addition to being connected to the telescopic output end of the first driving component 1110 of the electrode B, the adapter component 1140 is also slidably connected to the fixed guide rail 1170 through the sliding block 1180, thereby improving the movement stability of the adapter component 1140, thereby ensuring the smooth and reliable operation of the electrode B body 1132 and improving the welding quality.

[0149] The second cylinder fixing frame 1160 can be fixed on the supporting table 110 by screws, and the electrode B first driving component 1110 can be specifically fixed on the second cylinder fixing frame 1160 .

[0150] Since more structural components in the electrode B moving device 1100 are arranged vertically, it can be set inside the cabinet 100, and only the upper end of the electrode B body 1132 and the electrode B installation component 1131 need to be exposed upward above the support table 110, so as to simplify the overall structure and make the structure more compact. A through portion is correspondingly formed on the support table 110 to avoid exposing the upper end of the electrode B body 1132 and the electrode B installation component 1131.

[0151] The second sliding guide assembly may also be in other structural forms, such as a guide column and guide sleeve structure.

[0152] In some embodiments of the present application, if the vertical side plate a of the first workpiece 1 is spot-welded to the two adjacent opposite vertical side plates b, that is, the adjacent parts of the vertical side plate a and the two adjacent opposite vertical side plates b are both formed with a portion to be spot-welded c, such as Figure 1 As shown, and the two parts c to be spot welded are symmetrical, then the electrode A moving device 1000 is correspondingly set at two locations, and the electrode B moving device 1100 is correspondingly set at two locations. The two electrode A moving devices 1000 are symmetrically set, and the two electrode B moving devices 1100 are symmetrically set, as shown in FIG. Figure 4 , Figure 7 and Figure 8 shown.

[0153] In some embodiments of the present application, the electrode A movement device 1000 includes an electrode A driving component 1010 and an electrode A assembly 1020, the electrode A assembly 1020 includes a plurality of electrodes A1022, the plurality of electrodes A1022 are arranged at intervals along the second direction, and the electrode A driving component 1010 drives the electrode A assembly 1020 to move toward or away from the portion d to be spot welded.

[0154] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0155] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
