Description

[0001] The present invention relates to the technical field of welding, and in particular to a dual-robot intelligent interactive welding station. Background Art

[0002] At present, the battery trays in the field of new energy vehicles mostly adopt iFSW welding technology, fully automated solutions, and intelligent welding stations have emerged. However, the current intelligent welding stations have the following problems in welding battery trays: First, the welding quality of existing intelligent welding stations is low and the appearance of the battery trays after welding is poor; second, the existing intelligent welding stations only use a single robot to weld a single battery tray, which has a slow production cycle and low production efficiency; third, they cannot adapt to the processing errors of the battery trays of the die-casting blanks. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present invention is to provide a dual-robot intelligent interactive welding station with high welding quality and high welding production efficiency, which is particularly suitable for welding die-casting blanks and complex battery trays waiting for welding.

[0004] A dual-robot intelligent interactive welding station according to an embodiment of the present invention includes:

[0005] A base, the base is used to place a single workpiece to be welded;

[0006] A floating positioning mechanism, which is distributed in the base and is used for floating positioning of the workpiece to be welded;

[0007] A floating support mechanism, which is distributed in the base and is used for floatingly supporting the workpiece to be welded;

[0008] A pressing plate, the pressing plate is used to press on the workpiece to be welded and expose part or all of the predetermined welding track on the workpiece to be welded;

[0009] A clamping assembly, which is distributed at intervals along the periphery of the base and is used to clamp on the edge of the workpiece to be welded and the edge of the pressing plate;

[0010] A slide assembly, the slide assembly comprising a slide and a pressing member, the slide is movably arranged at the base in a transverse direction, the slide has a longitudinal beam extending longitudinally, the pressing member is arranged on the longitudinal beam, and is used to correspondingly press on different positions of the pressure plate when the slide moves to different designated positions;

[0011] A truss lifting device, the truss lifting device is used to lift the pressing plate to place the pressing plate on the workpiece to be welded and remove the pressing plate from the workpiece to be welded;

[0012] A dual robot is used to weld the workpieces to be welded simultaneously.

[0013] According to the dual-robot intelligent interactive welding station of the embodiment of the present invention, by placing a single workpiece to be welded on a base, and floatingly positioning the workpiece to be welded by a floating positioning mechanism and floatingly supporting the bottom of the workpiece to be welded by a floating support mechanism, it can adapt to workpieces to be welded with different processing errors, such as battery trays, and ensure the welding flatness and position accuracy of workpieces to be welded, such as battery trays, which is beneficial to improving welding quality and appearance. By pressing the pressure plate on the workpiece to be welded, pressing the edges of the workpiece to be welded and the edges of the pressure plate by the clamping assembly, and pressing the pressure plate by the clamping member in the slide assembly, any of the bottom box and the upper cover of the workpiece to be welded and the pressure plate can be prevented from shifting, and at the same time, it is beneficial for the upper cover and the bottom box to be pressed together at the predetermined welding trajectory, thereby improving the welding quality. Since the slide is movable in the lateral direction, the clamping member can be driven to move in the lateral direction, so that the clamping member is clamped on the corresponding position of the pressing plate according to the different positions of the predetermined welding track currently to be welded in the predetermined welding track exposed in the pressing plate area and arranged at lateral intervals on the workpiece to be welded, for example, it is clamped on the side of the pressing plate close to the predetermined welding track currently to be welded and does not affect the robot walking along the predetermined welding track currently to be welded.

[0077] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0078] Combine the following Figures 1 to 27 To describe the dual-robot intelligent interactive welding station 1000 according to an embodiment of the present invention.

[0079] like Figures 1 to 27 As shown, the dual-robot intelligent interactive welding station 1000 of the embodiment of the present invention is suitable for fully automatic welding of a workpiece 2000 to be welded, and the workpiece 2000 to be welded can be a battery tray (such as Fig. 27 As shown in the figure, a workpiece 2000 is waiting for welding, and the workpiece 2000 to be welded, such as a battery tray, includes a bottom box 2100 and an upper cover 2200 covering the bottom box 2100, and the upper cover 2200 and the bottom box 2100 need to be welded and fixed.

[0080] The dual robot intelligent interactive welding station 1000 according to an embodiment of the present invention may include a base 900, a floating positioning mechanism 300, a floating support mechanism 400, a pressure plate 220, a clamping assembly 210, a slide assembly 100, a truss lifting device 500 and a dual robot 600.

[0081] The base 900 is used to place a single workpiece 2000 to be welded, so that the dual robots 600 can weld the workpiece 2000 at the same time, thereby improving the welding production rhythm and production efficiency of the workpiece 2000 to be welded. The workpiece 2000 to be welded is stably supported by the base 900, which facilitates the robot 600 to process the workpiece 2000 to be welded, reduces the welding difficulty and improves the welding quality.

[0082] The floating positioning mechanism 300 is distributed in the base 900 (such as Figure 4As shown), it is used for floating positioning of the workpiece 2000 to be welded, with the purpose of improving the position accuracy of the workpiece 2000 to be welded on the base 900, so that the robot 600 can weld according to the predetermined welding trajectory of the workpiece 2000 to be welded, and avoid the walking trajectory of the robot 600 deviating from the predetermined welding trajectory, which is beneficial to improving the welding quality. Since the floating positioning mechanism 300 has the function of floating positioning of the workpiece 2000 to be welded, it can adapt to the different errors of the battery tray of the die-casting blank waiting for the workpiece 2000 to be welded, realize stable support, and ensure the welding flatness and position of the workpiece 2000 to be welded. In addition, the floating positioning mechanism 300 uses its own floating to buffer the impact of the workpiece 2000 to be welded when it is lowered, and plays a role in protecting the workpiece 2000 to be welded.

[0083] The floating support mechanism 400 is distributed in the base 900 (eg Figure 5 As shown), it is used for floating support of the workpiece 2000 to be welded. This is because there is a convex and uneven position at the bottom of the workpiece 200 to be welded, for example, the water cooling port at the bottom of the battery tray is uneven, and the side of the tube of the water cooling port protrudes downward from the lower surface of the bottom box 2100, and the workpiece 2000 to be welded of the die-cast blank has different processing errors. The floating support mechanism 400 supports the local convex position at the bottom of the workpiece 2000 to be welded, which can adapt to the different processing errors of the workpiece 2000 to be welded, achieve stable support, and ensure the welding flatness of the workpiece 2000 to be welded, which is beneficial to improving the welding quality. In addition, the floating support mechanism 400 uses its own floating to buffer the impact of the workpiece 2000 to be welded when it is lowered, and plays a role in protecting the workpiece 2000 to be welded. The number of floating support mechanisms can be selected according to the specific situation of the local convex position of the bottom of the workpiece 2000 to be welded. For example, when the workpiece 2000 to be welded is a battery tray, the two areas to be welded (i.e., water cooling areas) of the battery tray each have two water cooling ports, one for the water inlet and the other for the water outlet. Therefore, a single workpiece 2000 to be welded is floated supported by four floating support mechanisms 400.

[0084] like Figure 1 , Fig.23 , Figure 25-27As shown, the pressing plate 220 is used to press on the workpiece 2000 to be welded, and expose part or all of the predetermined welding track on the workpiece 2000 to be welded, and the exposed predetermined welding track is the first stage welding track 2300. By pressing the pressing plate 220 on the workpiece 2000 to be welded, the downward pressure applied to the pressing plate 220 is distributed as evenly as possible, which is conducive to improving the welding quality and protecting the workpiece 2000 to be welded; when the pressing plate 220 is pressed on the workpiece 2000 to be welded, the corresponding predetermined welding track on the workpiece 2000 to be welded is exposed, which facilitates the robot 600 to walk along the exposed predetermined welding track to weld the workpiece 2000 to be welded. It should be noted that when the workpiece 2000 to be welded has two areas to be welded spaced side by side, the number of the pressing plates 220 can be two, and the two pressing plates 220 are correspondingly pressed on the two areas to be welded.

[0085] like Figure 1-Figure 3 The clamping components 210 are distributed at intervals along the periphery of the base 900, and are used to clamp on the edges of the two workpieces 2000 to be welded and the edges of the pressure plate 220 to prevent any of the bottom box 2100 and the upper cover 2200 of the workpieces 2000 to be welded and the pressure plate 220 from shifting. At the same time, it is beneficial for the upper cover 2200 and the bottom box 2100 to be pressed together at a predetermined welding trajectory, reducing the difficulty of welding, thereby achieving reliable welding and improving welding quality.

[0086] like Figure 1-Figure 2 , Figure 11-Figure 15 As shown, the slide assembly 100 includes a slide 110 and a clamping member 120. The slide 110 is movably disposed on the base 900 in the transverse direction. The slide 110 has a longitudinally extending longitudinal beam 111. The clamping member 120 is disposed on the longitudinal beam 111 and is used to clamp on different positions of the pressure plate 220 accordingly when the slide 110 moves to different designated positions. Since the slide 110 is movable in the transverse direction, the clamping piece 120 can be driven to move in the transverse direction so that the clamping piece 120 can be clamped at the corresponding position on the pressing plate 220 according to the different positions of the current predetermined welding track to be welded in the predetermined welding track exposed in the area of ​​the pressing plate 220 and arranged laterally at intervals on the workpiece 2000 to be welded. For example, it can be clamped on one side of the pressing plate 220 close to the current predetermined welding track to be welded and does not affect the robot 600 from walking along the current predetermined welding track to be welded. In this way, the upper cover 2200 and the bottom box 2100 can be made to fit more closely at the current predetermined track to be welded, thereby reducing the difficulty of welding, effectively improving the welding quality, and ensuring the welding appearance.

[0087] like Figure 1 and Fig.23As shown, the truss lifting device 500 is used to lift the pressing plate 220, so as to place the pressing plate 220 on the workpiece 2000 to be welded and remove the pressing plate 220 from the workpiece 2000 to be welded. By providing the truss lifting device 500, the pressing plate 220 can be automatically, safely and reliably lifted, thereby improving the production cycle and production efficiency. When the workpiece 2000 to be welded has two welding areas spaced side by side, there can be two pressing plates 220, and accordingly, there can be two truss lifting devices 500, so that two pressing plates 200 can be lifted simultaneously by two truss lifting devices 500, thereby improving the production cycle and production efficiency.

[0088] The dual robots 600 are used to simultaneously weld a single workpiece 2000 to be welded. For example, if the workpiece 2000 to be welded has two areas to be welded, one robot 600 welds one area to be welded, and the other robot 600 welds the other area to be welded. The two areas to be welded of the single workpiece 2000 to be welded are welded simultaneously by two robots 600, thereby improving the production cycle and production efficiency.

[0089] According to the dual robot intelligent interactive welding station 1000 of the embodiment of the present invention, by placing a single workpiece 2000 to be welded on a base 900, and floatingly positioning the workpiece 2000 to be welded by a floating positioning mechanism 300 and floatingly supporting the bottom of the workpiece 2000 to be welded by a floating supporting mechanism 400, it can adapt to workpieces 2000 to be welded with different processing errors, such as a battery tray, and ensure the welding flatness and position accuracy of the workpiece 2000 to be welded, such as a battery tray, which is beneficial to improving the welding quality and appearance. By pressing the pressure plate 220 onto the workpiece 2000 to be welded, by pressing the clamping assembly 210 onto the edge of the workpiece 2000 to be welded and the edge of the pressure plate 220, and by pressing the clamping member 120 in the slide assembly 100 onto the pressure plate 220, any displacement of the bottom box 2100, the upper cover 2200 and the pressure plate 220 of the workpiece 2000 to be welded can be prevented, and at the same time, the upper cover 2200 and the bottom box 2100 are facilitated to be pressed together at the predetermined welding trajectory, thereby improving the welding quality. Since the slide 110 is movable in the lateral direction, the clamping member 120 can be driven to move in the lateral direction, so that the clamping member 120 can be clamped at the corresponding position on the pressing plate 220 according to the different positions of the predetermined welding track currently to be welded in the predetermined welding track exposed in the pressing plate 220 area and arranged at lateral intervals on the workpiece 2000 to be welded, for example, it is clamped on the side of the pressing plate 220 close to the predetermined welding track currently to be welded and does not affect the robot 600 walking along the predetermined welding track currently to be welded, so that the upper cover 2200 and the bottom box 2100 can be more closely fitted at the predetermined track currently to be welded, reducing the difficulty of welding, effectively improving the welding quality, and ensuring the welding appearance. Since the dual robots 600 can weld a single workpiece 2000 to be welded on the same base 900 at the same time, the production cycle and production efficiency are improved. In summary, the dual-robot intelligent interactive welding station 1000 of the embodiment of the present invention can improve the welding quality and appearance of the workpiece 2000 to be welded, such as a battery tray, and improve the welding production cycle and welding production efficiency. It is particularly suitable for welding die-casting blanks and complex workpieces 2000 to be welded, such as a battery tray.

[0090] It should be noted that, after the pressure plate 220 is pressed tightly against the workpiece 2000 to be welded, if there is still an unexposed predetermined welding track on the workpiece 2000 to be welded, the unexposed predetermined welding track is the second-stage welding track 2400. The exposed predetermined welding track can be welded first, and then the pressure plate 220 can be removed, and then the second-stage welding track 2400 can be welded.

[0091] In some embodiments, in combination Figure 4 , Figure 6 and Figure 7As shown, the floating positioning mechanism 300 includes a shell 320 and a positioning column 330. The shell 320 is arranged on the base 900. A mounting cavity 321 extending vertically is provided in the shell 320. The positioning column 330 is slidably arranged in the mounting cavity 321 between a first position and a second position vertically. In the first position, the positioning column 330 at least partially protrudes from the shell 320 for positioning the workpiece 2000 to be welded. In the second position, the positioning column 330 is located in the mounting cavity 321 or the length of the positioning column 330 protruding from the shell 320 is less than that in the first position. Through the above-mentioned arrangement, when the floating positioning mechanism 300 needs to position the workpiece 2000 to be welded, the positioning column 330 can be controlled to be in the first position, and the portion of the positioning column 330 protruding from the shell 320 cooperates with the positioning hole on the workpiece 2000 to be welded to achieve positioning of the workpiece 2000 to be welded; when the workpiece 2000 to be welded is processed, the positioning column 330 can be driven to slide in a direction away from the workpiece 2000 to drive the positioning column 330 to slide in a direction away from the workpiece 2000 to be welded, and the positioning column 330 is separated from the workpiece 2000 to be welded, which can facilitate the removal of the workpiece 2000 to be welded, solves the problem that the positioning column 330 and the positioning hole on the workpiece 2000 to be welded are stuck, making it difficult to disassemble the workpiece 2000 to be welded, and improves the reliability of the floating positioning mechanism 300.

[0092] That is to say, by configuring the shell 320 to have an installation cavity 321 extending vertically, and configuring the positioning column 330 to be slidably disposed in the installation cavity 321 between a first position and a second position vertically, while the positioning column 330 is used to position the workpiece 2000 to be welded, the difficulty of disassembling the workpiece 2000 to be welded can be reduced.

[0093] At the same time, by setting up the shell 320, on the one hand, the shell 320 can be used to support the positioning column 330, thereby ensuring the working performance of the positioning column 330 to a certain extent. On the other hand, the floating positioning mechanism 300 can be set on the base 900 to reduce the difficulty of assembling the floating positioning mechanism 300.

[0094] It should be noted that the sliding of the positioning column 330 can be automatically driven or manually driven.

[0095] In some embodiments, the floating positioning mechanism 300 further includes a positioning driver connected to the positioning column 330 , and the positioning driver is used to drive the positioning column 330 to slide.

[0096] The positioning drive member mentioned here may be an oil cylinder 380, an air cylinder or other mechanism that can drive the positioning column 330 to move linearly, and the present application does not limit this.

[0097] In other embodiments, the positioning column 330 is connected to a driving rod, a portion of which is located outside the shell 320. The staff can drive the positioning column 330 to move by moving the driving rod to drive the positioning column 330 out of the positioning hole of the workpiece 2000 to be welded.

[0098] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, the positioning drive member is constructed as a cylinder 380, and the piston 381 of the cylinder 380 can move vertically. The piston 381 is provided with an internal thread. A connecting column 342 is provided at one end of the positioning column 330, and the connecting column 342 is provided with an external thread. The connecting column 342 is threadedly connected to the piston 381 to achieve a mating connection between the cylinder 380 and the positioning column 330.

[0099] Among them, by setting the oil cylinder 380, the driving method of the positioning column 330 can be made more automated, which is conducive to the intelligence of the fixture 200, and the connection method between the piston 381 and the positioning column 330 is simple, which reduces the cost of the floating positioning mechanism 300.

[0100] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, the top of the positioning column 330 has a positioning portion 331, and the cross-sectional area of ​​the positioning portion 331 gradually decreases in the direction away from the housing 320. This allows the positioning column 330 to cooperate with positioning holes of different apertures, further improving the applicability of the floating positioning mechanism 300.

[0101] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, the floating positioning mechanism 300 further includes a mounting platform 340 and a first elastic member 350. The mounting platform 340 is slidably disposed in the mounting cavity 321, and the positioning column 330 is slidably matched with the mounting platform 340. Thus, the positioning column 330 is slidably disposed in the mounting cavity 321, reducing the difficulty of assembling the positioning column 330.

[0102] It should be noted that when a mounting table 340 is provided, the positioning drive component is connected to the mounting table 340, and the positioning drive component is used to drive the mounting table 340 to slide to drive the positioning column 330 to separate from the workpiece 2000 to be welded, that is, the positioning drive component is used to drive the mounting table 340 to move, so as to control the sliding of the positioning column 330 and reduce the sliding difficulty of the positioning column 330.

[0103] Optionally, combined Figure 6 , Figure 7 and Figure 8As shown, the first elastic member 350 is disposed between the positioning column 330 and the mounting platform 340, and the first elastic member 350 has an elastic tendency to drive the positioning column 330 to slide in a direction away from the mounting platform 340. It should be noted that, because the precision of different workpieces 2000 to be welded is different, when the workpiece 2000 to be welded is placed on the fixture 200, there may be an error in the vertical distance between the positioning hole on the workpiece 2000 to be welded and the positioning column 330, and there may also be an error in the size of the positioning hole on the workpiece 2000 to be welded. In order to make the positioning column 330 better match the positioning hole of the workpiece 2000 to be welded, the embodiment of the present application arranges the first elastic member 350 between the positioning column 330 and the mounting platform 340, so that the positioning column 330 has an elastic tendency to slide in a direction away from the mounting platform 340, that is, the positioning column 330 can float vertically relative to the mounting platform 340, so that it can match different positioning holes, thereby improving the applicability of the floating positioning mechanism 300.

[0104] The first elastic member 350 mentioned here may be a spring, which can reduce the use cost of the first elastic member 350 while ensuring the working performance of the first elastic member 350 .

[0105] Of course, in some other embodiments, the first elastic member 350 may also be a rubber block.

[0106] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, the floating positioning mechanism 300 also includes a floating positioning mounting portion 310, and the shell 320 is fixed to the floating positioning mounting portion 310. The floating positioning mounting portion 310 is suitable for being installed on the base 900 to realize setting the floating positioning mechanism 300 on the base 900, thereby ensuring the stability of the main floating positioning mechanism 300, which is beneficial to ensuring the working performance of the floating positioning mechanism 300.

[0107] In some embodiments, the shell 320 and the floating positioning mounting portion 310 are separate parts. In this way, after the floating positioning mounting portion 310 is fixed to the base 900, the position of the shell 320 can also be adjusted by adjusting the relative position between the shell 320 and the floating positioning mounting portion 310, which is beneficial to improve the position accuracy of the shell 320 on the base 900 and improve the accuracy of the floating positioning mechanism 300 in positioning the workpiece 2000 to be welded.

[0108] Among them, the adjustment of the relative position between the shell 320 and the floating positioning mounting part 310 mentioned here can be an operation before fixing the shell 320 to the floating positioning mounting part 310, or the shell 320 and the floating positioning mounting part 310 can be set to be detachably connected, and the fixed connection between the shell 320 and the floating positioning mounting part 310 is released, and the position of the shell 320 is adjusted before fixing the shell 320 to the floating positioning mounting part 310.

[0109] In summary, the floating positioning mechanism 300 is provided with a first elastic member 350 between the positioning column 330 and the mounting platform 340, so that the positioning column 330 can float vertically relative to the mounting platform 340, so that the positioning column 330 can cooperate with positioning holes of different sizes (i.e., there are processing accuracy errors), thereby improving the applicability of the floating positioning mechanism 300; at the same time, the mounting platform 340 can drive the positioning column 330 to slide in the direction of separating from the workpiece 2000 to be welded, thereby solving the problem that the positioning column 330 and the positioning hole are stuck, making it difficult to disassemble the workpiece 2000 to be welded, thereby improving the reliability of the floating positioning mechanism 300; and the shell 320 and the floating positioning mounting part 310 are separate structures. After the floating positioning mounting part 310 is fixed to the base 900, the position of the shell 320 can also be adjusted by adjusting the relative position between the shell 320 and the floating positioning mounting part 310, which is beneficial to improving the position accuracy of the shell 320 on the base 900 and improving the accuracy of the floating positioning mechanism 300 in positioning the workpiece 2000 to be welded.

[0110] In some embodiments, the floating positioning mechanism 300 also includes a floating positioning mounting portion 310, which is fixed to the shell 320. The floating positioning mounting portion 310 is fixed on the base 900 and can fine-tune the planar position of the shell on the base 900. This is beneficial to improving the position accuracy of the shell 320 on the base 900, and further improving the positioning accuracy of the floating positioning mechanism 300.

[0111] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, the floating positioning mounting portion 310 includes a first portion 311 and a second portion 312 which are arranged at an angle, the first portion 311 extends vertically, the shell 320 is fixed to the first portion 311, and the second portion 312 is used to be installed to the base 900, so as to realize the installation of the floating positioning mechanism 300 to the base 900, and the first portion 311 extends vertically. After the shell 320 is fixed to the first portion 311, the shell 320 can adjust its position in the vertical direction, which is beneficial to improve the position accuracy of the shell 320 on the base 900, and further improve the positioning accuracy of the floating positioning mechanism 300.

[0112] It should be noted that the first portion 311 and the second portion 312 may form an angle of 90 degrees, an angle of 85 degrees, or other angles, and the present application is not limited thereto.

[0113] In some embodiments, the first part 311 is provided with a shell mounting hole, and the first fastener passes through the shell mounting hole and is connected to the shell 320, thereby fixing the shell 320 to the first part 311, wherein the first fastener can be a screw or a bolt, with high connection reliability and low cost.

[0114] In some embodiments, a plurality of shell mounting holes are provided, and the plurality of shell mounting holes are arranged vertically. The first fastener can be connected to the shell 320 by passing through different shell mounting holes, thereby achieving adjustment of the vertical position of the shell 320.

[0115] In other embodiments, the shell mounting hole is a long hole extending vertically. After the first fastener passes through the shell mounting hole, it moves in the shell mounting hole to adjust the vertical position of the shell 320, and then the fastener is tightened to fix the shell 320 to the first part 311.

[0116] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, the second part 312 includes a first fixing part 3121, an adjustment piece 3122 and a second fixing part 3123, the adjustment piece 3122 is replaceably arranged between the first fixing part 3121 and the second fixing part 3123, the first part 311 and the first fixing part 3121 are integrated and are arranged at an angle, the first fixing part 3121 is used to connect with the base 900, so as to realize the fixation of the floating positioning mechanism 300, the first part 311 and the first fixing part 3121 are integrated, which ensures the strength of the overall structure of the floating positioning mounting part 310 and ensures the installation reliability of the shell 320.

[0117] Through the above arrangement, when the floating positioning mechanism 300 is installed on the base 900, the second fixing part 3123 is first fixed by the second fastener, and then the adjustment piece 3122 is placed between the second fixing part 3123 and the first fixing part 3121, and then the first fixing part 3121 is fixed by the third fastener. When it is found through testing that the installation position of the first fixing part 3121 is incorrect, the first fixing part 3121 can be removed and replaced with an adjustment piece 3122 of different thickness to adjust the position of the first fixing part 3121. After the first fixing part 3121 is installed in place, the first fixing part 3121 and the second fixing part 3123 are fixedly connected by the third fastener, so as to further improve the installation stability of the floating positioning mechanism 300.

[0118] In some embodiments, the first portion 311 and the second portion 312 form an angle of 90 degrees, the first fixing portion 3121 includes a first side wall and a second side wall that intersect and are adjacent to each other, and an adjustment sheet 3122 is provided between the second fixing portion 3123 and the first side wall and the second side wall.

[0119] In some embodiments, in combination Figure 5 , Figure 6 and Figure 7 As shown, the floating positioning mechanism 300 also includes a connecting member 360 and a first limiting member 370. The connecting member 360 is fixedly connected to the positioning column 330 and is slidably connected to the mounting platform 340. The first limiting member 370 is arranged on the mounting platform 340. The first limiting member 370 is suitable for abutting against the connecting member 360 to limit the connecting member 360 from being separated from the mounting platform 340.

[0120] The positioning column 330 is slidably connected to the mounting platform 340 via a connecting member 360 . This connection method is simple and reduces the cost of the floating positioning mechanism 300 .

[0121] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, a third slide groove 341 is provided on the side of the mounting platform 340 facing the positioning column 330, the first limit member 370 is fixed to the notch of the third slide groove 341 by a fastener, the connecting member 360 is constructed as a bolt, the bolt head of the connecting member 360 is located in the third slide groove 341, and the screw rod of the connecting member 360 is passed through the first limit member 370 and is threadedly connected to the positioning column 330.

[0122] In the embodiment of the present application, the structure of the connecting member 360 and the mounting platform 340 is simple and easy to assemble, which further reduces the cost of the floating positioning mechanism 300.

[0123] In some embodiments, in combination Figure 6 , Figure 7 and Figure 8 As shown, the first limiting member 370 is provided with a first through hole 371, and the connecting member 360 is slidably penetrated in the first through hole 371. The sliding cooperation between the connecting member 360 and the first through hole 371 improves the sliding stability of the connecting member 360, and further improves the sliding stability of the positioning column 330.

[0124] In some embodiments, the first elastic member 350 is constructed as a spring, which is sleeved on the connecting member 360, and the two ends of the first elastic member 350 are respectively stopped by the positioning column 330 and the first stop member 370. By sleeved the first elastic member 350 on the connecting member 360, it is ensured that the first elastic member 350 can only be elastically deformed in the vertical direction, thereby improving the floating reliability of the positioning column 330.

[0125] In some embodiments, Figure 8 As shown, the installation cavity 321 includes a first slide groove 3211 and a second slide groove 3212 extending vertically, the first slide groove 3211 and the second slide groove 3212 have different opening areas, the positioning column 330 is slidably matched with the first slide groove 3211, and the mounting platform 340 is slidably matched with the second slide groove 3212. The sliding stability of the positioning column 330 and the sliding stability of the mounting platform 340 are ensured, and the reliability of the floating positioning mechanism 300 is improved.

[0126] In some embodiments, Figure 8 As shown, the opening area of ​​the first slide groove 3211 is smaller than the opening area of ​​the second slide groove 3212. When the mounting platform 340 slides toward the first slide groove 3211, the inner wall of the second slide groove 3212 can limit the sliding range of the mounting platform 340, thereby preventing the positioning column 330 from protruding too much from the shell 320, thereby avoiding affecting the processing of the workpiece 2000 to be welded to a certain extent.

[0127] In some embodiments, Figure 8 As shown, the housing 320 is further provided with an avoidance groove 3213 connected to the second slide groove 3212. When the side of the mounting platform 340 facing the first slide groove 3211 abuts against the inner wall of the second slide groove 3212, the first stopper 370 is located in the avoidance groove 3213. By providing the avoidance groove 3213, the first stopper 370 is prevented from colliding with the inner wall of the mounting cavity 321, thereby reducing the risk of damage to the floating positioning mechanism 300.

[0128] In some embodiments, the housing 320 is an integrally formed part, and the first slide groove 3211 and the second slide groove 3212 are connected to penetrate the housing 320 .

[0129] In some embodiments, Figure 5 As shown, at least two floating positioning mechanisms 300 are disposed on the base 900 , and the at least two floating positioning mechanisms 300 cooperate to simultaneously position the workpiece 2000 to be welded, so as to improve the positioning effect of the fixture 200 .

[0130] In some embodiments, in combination Figure 5 , Fig. 9 and Fig.10As shown, the floating support mechanism 400 includes a mounting portion 410, a first support portion 440, and a second support portion 450. The mounting portion 410 is disposed on the base 900, and the first support portion 440 and the second support portion 450 are both disposed on the mounting portion 410. The height of the first support portion 440 protruding from the mounting portion 410 is greater than the height of the second support portion 450 protruding from the mounting portion 410. The first support portion 440 is used to support the bottom wall of the workpiece 2000 to be welded, and the second support portion 450 is used to support the bottom local convex position of the workpiece 2000 to be welded. For example, when the workpiece 2000 to be welded is a battery tray, the second support portion supports the bottom water cooling port position of the battery tray. That is to say, by setting the height of the first support portion 440 protruding from the mounting portion 410 to be greater than the height of the second support portion 450 protruding from the mounting portion 410, it is possible to utilize the first support portion 440 to support the bottom wall of the workpiece 2000 to be welded and utilize the second support portion 450 to support the local convex position of the bottom of the workpiece 2000 to be welded, so that the floating support mechanism 400 of the present application not only supports the workpiece 2000 to be welded, but also can provide good support for the local convex position of the bottom of the workpiece 2000 to be welded, thereby reducing the risk of compression deformation of the workpiece 2000 to be welded, and is beneficial to improving the processing accuracy of the workpiece 2000 to be welded.

[0131] It should be noted that in some processing processes of the workpiece 2000 to be welded, downward pressure will be applied to the workpiece 2000 to be welded. For example, in the welding process of the workpiece 2000 to be welded, the robot will apply pressure to the workpiece 2000 to be welded.

[0132] Based on this, the embodiment of the present application can effectively reduce the risk of compression deformation of the workpiece 2000 to be welded by providing a floating support mechanism 400.

[0133] In some embodiments, Fig. 9 As shown, the mounting portion 410 is provided with a first mounting hole 411 passing through it, and the first mounting hole 411 is used for bolts to pass through. When the mounting portion 410 needs to be fixed to the base 900, the bolt passes through the first mounting hole 411 and is threadedly connected to the base 900, thereby fixing the mounting portion 410 on the base 900, so that the fixing method of the mounting portion 410 is simple and the installation is highly secure.

[0134] It should be understood that the mounting portion 410 and the base 900 may also be connected by welding, clamping, etc., and this application does not limit this.

[0135] In some embodiments, in combination Fig. 9 and Fig.10As shown, the floating support mechanism 400 also includes a slider 420 and a second elastic member 430. The slider 420 is slidably disposed on the mounting portion 410 along the vertical direction. The first support portion 440 is disposed on the slider 420. The second elastic member 430 is disposed on the side of the slider 420 away from the first support portion 440. The second elastic member 430 has an elastic tendency to drive the slider 420 to slide in a direction away from the mounting portion 410. Thereby, the first support part 440 can float in the vertical direction, so that in the process of placing the workpiece 2000 to be welded on the base 900, the workpiece 2000 to be welded is gradually lowered, and the surface of the workpiece 2000 to be welded first contacts with the first support part 440, and as the workpiece 2000 to be welded continues to be lowered, the first support part 440 moves downward, pushing the slider 420 to move downward, and the second elastic member 430 is elastically compressed. When the water cooling port of the workpiece 2000 to be welded stops with the second support part 450, the workpiece 2000 to be welded is completely placed on the fixture 200. At this time, the second support part 450 supports the water cooling port, and the first support part 440 stops with the workpiece 2000 to be welded under the action of the second elastic member 430.

[0136] In some embodiments, Fig. 9 As shown, two first support parts 440 are provided, and the two first support parts 440 are both connected to the top of the slider 420, and the second support part 450 is located between the two first support parts 440. When the workpiece 2000 to be welded is completely placed on the fixture 200, the second support part 450 supports the water cooling port, and the two first support parts 440 respectively support the parts of the workpiece 2000 to be welded located on both sides of the water cooling port. The reliability of the floating support mechanism 400 is further improved by supporting the workpiece 2000 to be welded by the two first support parts 440, and the two first support parts 440 respectively support the parts of the workpiece 2000 to be welded located on both sides of the water cooling port, which improves the uniformity of the overall force of the water cooling port part and further reduces the risk of deformation of the workpiece 2000 to be welded.

[0137] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the mounting portion 410 is provided with a first through hole 412 extending in a vertical direction. The first through hole 412 passes through the mounting portion 410 . When the mounting portion 410 is mounted on the base 900 , the base 900 closes the opening at the bottom end of the first through hole 412 .

[0138] Optionally, combined Figure 5 , Fig. 9 and Fig.10 As shown, the slider 420 is slidably disposed in the first through hole 412, the second elastic member 430 is disposed in the first through hole 412 and is located at the bottom end of the slider 420, one end of the second elastic member 430 abuts against the slider 420, and the other end of the second elastic member 430 is suitable for abutting against the base 900.

[0139] In the embodiment of the present application, the mounting portion 410 has a simple structure, which reduces the production cost of the mounting portion 410 , and the matching method of the second elastic member 430 , the slider 420 and the mounting portion 410 is simple, which improves the assembly efficiency of the floating support mechanism 400 .

[0140] In some embodiments, Fig. 9 As shown, there are multiple second elastic members 430, which are arranged at intervals, and the arrangement direction of the multiple second elastic members 430 is parallel to the arrangement direction of the two first support parts 440. The multiple second elastic members 430 ensure the stability of the slider 420 floating up and down.

[0141] In some embodiments, in combination Fig. 9 and Fig.10 As shown, a positioning groove 421 is provided at the bottom of the slider 420, and there are multiple positioning grooves 421. The multiple positioning grooves 421 correspond one-to-one to the multiple second elastic members 430. Parts of the second elastic members 430 are inserted into the corresponding positioning grooves 421. The positioning grooves 421 limit the position of the second elastic members 430, further ensuring the stability of the slider 420 floating up and down.

[0142] In some embodiments, the second elastic member 430 is configured as a spring, which has a simple structure and is easy to obtain materials, thereby reducing the cost of the floating support mechanism 400 .

[0143] Of course, in some other embodiments, the second elastic member 430 may also be a plastic elastic member or other elastic structure, which is not limited in the present application.

[0144] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the floating support mechanism 400 further includes a locking assembly 460, which is configured to lock the slider 420 when the first support portion 440 supports the workpiece 2000 to be welded. In this way, when the workpiece 2000 to be welded is completely placed on the fixture 200, the slider 420 is locked by the locking assembly 460, which limits the movement of the slider 420, thereby limiting the movement of the first support portion 440, so that the first support portion 440 can provide support for the workpiece 2000 to be welded, and the reliability of the support of the first support portion 440 is ensured by locking the slider 420 by the locking assembly 460.

[0145] In addition, when the processing of the workpiece 2000 to be welded is completed, the locking assembly 460 can also unlock the slider 420, so that the first support portion 440 can float up and down again.

[0146] It should be noted that when the workpiece 2000 to be welded is a battery tray, when it is placed on the fixture 200, the bottom local convex part of the workpiece 200 to be welded, such as the bottom of the water cooling port of the battery tray, has a height difference with the bottom surface of the workpiece 2000 to be welded, and the height difference may be different for different workpieces 2000 to be welded. The floating support mechanism 400 provided in the embodiment of the present application, the first support part 440 can stop against the bottom surface of any workpiece 2000 to be welded under the action of the second elastic member 430, and stably supports the workpiece 2000 to be welded under the action of the locking assembly 460, which effectively improves the applicability of the floating support mechanism 400.

[0147] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the locking assembly 460 includes a locking rod 462 that reciprocates in the horizontal or vertical direction. The locking rod 462 is provided with a first inclined surface 4621 on the side facing the slider 420. The slider 420 is provided with a second inclined surface 422 that is opposite to the first inclined surface 4621. The first inclined surface 4621 and the second inclined surface 422 are used to stop and cooperate with each other to lock the slider 420. The horizontal, vertical and vertical directions intersect. The longitudinal direction mentioned here can be understood as Figure 1 The X direction shown in the figure means that the locking assembly 460 has a locking rod 462, and the reciprocating movement direction of the locking rod 462 intersects with the moving direction of the slider 420, so as to control the locking rod 462 to move away from or close to the slider 420.

[0148] Among them, since the locking rod 462 is provided with a first inclined surface 4621 on the side facing the slider 420, and the slider 420 is provided with a second inclined surface 422 opposite to the first inclined surface 4621, when the locking rod 462 is controlled to move in a direction close to the slider 420, the first inclined surface 4621 and the second inclined surface 422 are stopped and cooperated to lock the slider 420, thereby limiting the downward movement of the slider 420, so that the first support portion 440 can stably support the workpiece 2000 to be welded; when the locking rod 462 is controlled to move in a direction away from the slider 420, the first inclined surface 4621 and the second inclined surface 422 are separated, and the lock on the slider 420 is released, so that the slider 420 can float up and down again.

[0149] In addition, by setting the first inclined surface 4621 and the second inclined surface 422, the slider 420 can be locked by abutting the locking rod 462 against the second inclined surface 422 at any position. In other words, no matter where the slider 420 is in the vertical direction, the locking assembly 460 can lock the slider 420 by abutting against the second inclined surface 422, thereby ensuring the reliability of the floating support mechanism 400.

[0150] In some embodiments, in combination Fig. 9 and Fig.10As shown, in the direction from top to bottom, the second inclined surface 422 extends obliquely in a direction away from the locking rod 462. In this way, when the first inclined surface 4621 and the second inclined surface 422 are abutted and matched, it is easy to overcome the downward gravity of the locking rod 462, so that the first inclined surface 4621 and the second inclined surface 422 can effectively lock the slider 420 when the abutment and match.

[0151] In one embodiment, the angle between the second inclined surface 422 and the vertical direction is A, and A satisfies: 5°≤A≤10°. When A is small, when the locking assembly 460 is in a locked state, the upward force of the locking rod 462 on the slider 420 is too small. If the pressure of the workpiece 2000 to be welded on the first support part 440 is too large, the first support part 440 has the risk of sliding down, and the reliability of the floating support mechanism 400 is too poor; when A is large, it is easy to cause the structural strength of the slider 420 to decrease, and the slider 420 has the risk of breaking.

[0152] Among them, the present application sets A to satisfy: 5°≤A≤10°, which ensures the structural strength of the slider 420 while improving the stability of the locking assembly 460 locking the slider 420 and improving the reliability of the floating support mechanism 400.

[0153] In a specific example, the angle A between the second inclined surface 422 and the vertical direction is 5°, 6°, 7°, 8°, 9° or 10°.

[0154] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the mounting portion 410 is provided with a second through hole 413, the second through hole 413 is connected to the first through hole 412 and is arranged opposite to the second inclined surface 422, the locking assembly 460 also includes a locking rod driving member 461, the locking rod 462 is arranged in the second through hole 413, the locking rod driving member 461 is connected to the outer side of the mounting portion 410, the locking rod driving member 461 is constructed to have an output end 4611 that can perform reciprocating linear motion, the output end 4611 of the locking rod driving member 461 is connected to the locking rod 462, so that the locking rod driving member 461 can drive the locking rod 462 to move toward the slider 420, and the locking rod driving member 461 can also drive the locking rod 462 to move in the direction away from the slider 420.

[0155] Among them, the locking rod driving component 461 can be a mechanism such as an oil cylinder, a pneumatic cylinder, an electric push rod, etc., as long as it can drive the locking rod 462 to perform reciprocating motion, and this application does not impose any restrictions on this.

[0156] In the embodiment of the present application, the locking assembly 460 has a simple structure, which reduces the cost of the floating support mechanism 400.

[0157] In some embodiments, the output end 4611 of the locking rod driving member 461 is suitable for reciprocating linear motion in the horizontal direction, and the second through hole 413 extends in the horizontal direction.

[0158] In the embodiment of the present application, the second through hole 413 extends in the horizontal direction, which facilitates the processing of the first through hole 412 on the one hand, and facilitates the installation of the locking assembly 460 on the other hand, effectively reducing the cost of the floating support mechanism 400.

[0159] In some specific embodiments, a threaded rod is provided on the side of the locking rod 462 away from the slider 420 , an output end 4611 of the locking rod driving member 461 is provided with an internal thread, and the locking rod 462 is threadedly connected to the output end 4611 of the locking rod driving member 461 .

[0160] In the embodiment of the present application, the connection method between the locking rod 462 and the output end 4611 of the locking rod driving member 461 is simple, which improves the assembly efficiency of the floating support mechanism 400.

[0161] In some embodiments, in combination Figure 8 and Fig. 9 As shown, the floating support mechanism 400 further includes a second stopper 470, which is used to abut against the slider 420 to limit the movement range of the slider 420. This can avoid the slider 420 completely detaching from the mounting portion 410 to a certain extent, thereby ensuring the overall stability of the floating support mechanism 400.

[0162] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the second support portion 450 includes a vertical portion 451 extending in the vertical direction and a horizontal portion 452 extending in the horizontal direction, the bottom end of the vertical portion 451 is connected to the top of the mounting portion 410, the top end of the vertical portion 451 is connected to the horizontal portion 452, and the horizontal portion 452 extends in the horizontal direction and extends to just above the first through hole 412. The second stopper 470 is connected to the bottom surface of the horizontal portion 452 so that the second stopper 470 can stop against the slider 420.

[0163] Among them, the horizontal portion 452 not only increases the contact area with the water cooling port and improves the supporting stability of the second supporting portion 450, but also provides an installation position for the second limiting member 470, thereby reducing the difficulty of installing the second limiting member 470.

[0164] In some embodiments, the second stopper 470 is configured as a bolt, and the second stopper 470 is threadedly connected to the second support portion 450 so that the second stopper 470 is vertically adjustable. In other words, the highest position of the slider 420 is adjustable, that is, the highest position of the first support portion 440 is adjustable.

[0165] Through the above arrangement, when the floating support mechanism 400 is used to support workpieces 2000 to be welded of different specifications, the highest position of the first support part 440 can be adjusted by adjusting the position of the second limit member 470, so that the first support part 440 can support more products, thereby effectively improving the applicability of the floating support mechanism 400.

[0166] In some embodiments, the first support portion 440 is connected to the top of the slider 420 through a fastener, and a replaceable adjustment gasket 480 is arranged between the first support portion 440 and the slider 420, wherein the fastener can be a screw or a bolt, with high connection stability and low cost.

[0167] In the embodiment of the present application, by replacing the adjustment gasket 480 of different thicknesses between the first support portion 440 and the slider 420, the height of the first support portion 440 relative to the slider 420 can be adjusted. That is to say, in addition to being able to adjust the highest position of the first support portion 440 through the second limit member 470, the highest position of the first support portion 440 can also be adjusted by replacing the adjustment gasket 480 of different thicknesses between the first support portion 440 and the slider 420, thereby further improving the applicability of the floating support mechanism 400.

[0168] In some specific embodiments, the second support portion 450 is connected to the top of the mounting portion 410 through a fastener, and a replaceable adjustment gasket 480 is provided between the second support portion 450 and the mounting portion 410, wherein the fastener may be a screw or a bolt, with high connection stability and low cost.

[0169] In the embodiment of the present application, by replacing the adjustment gasket 480 of different thicknesses between the second support portion 450 and the mounting portion 410 , the height of the second support portion 450 can be adjusted, further improving the applicability of the floating support mechanism 400 .

[0170] In some embodiments, in combination Fig. 9 and Fig.10 As shown, the floating support mechanism 400 further includes a third support portion 490, which is disposed on the top of the mounting portion 410 and is used to support the frame of the workpiece 2000 to be welded. This further improves the stability of the floating support mechanism 400 in supporting the workpiece 2000 to be welded.

[0171] In summary, the floating support mechanism 400 of the present application includes a first support portion 440, a second support portion 450 and a third support portion 490. The first support portion 440 can support the bottom wall of the workpiece 2000 to be welded, the second support portion 450 can support the portion of the workpiece 2000 to be welded that protrudes from the water cooling port, and the third support portion 490 can be used to support the frame of the workpiece 2000 to be welded to maximize the stability of the workpiece 2000 to be welded.

[0172] In some embodiments, the third support portion 490 is connected to the top of the mounting portion 410 through a fastener, and a replaceable adjustment gasket 480 is arranged between the third support portion 490 and the mounting portion 410, wherein the fastener may be a screw or a bolt, with high connection stability and low cost.

[0173] In the embodiment of the present application, by replacing the adjustment gasket 480 of different thicknesses between the third support portion 490 and the mounting portion 410, the height of the third support portion 490 can be adjusted, further improving the applicability of the floating support mechanism 400.

[0174] That is to say, the first support portion 440 of the floating support mechanism 400 of the present application can support the bottom wall of the workpiece 2000 to be welded, and the second support portion 450 can support the local convex position of the bottom of the workpiece 2000 to be welded, such as the water cooling port position of the battery tray, so as to provide good support for the local convex position of the workpiece 2000 to be welded, reduce the risk of compression deformation of the workpiece 2000 to be welded, and help improve the processing accuracy and welding quality of the workpiece 2000 to be welded; the first support portion 440 can stop against the bottom surface of any workpiece 2000 to be welded under the action of the second elastic member 430, and stably support the workpiece 2000 to be welded under the action of the locking assembly 460, thereby effectively improving the applicability of the floating support mechanism 400; the workpiece 2000 to be welded is supported by two first support portions 440, and the reliability of the support of the floating support mechanism 400 is further improved. In addition, the two first support portions 440 respectively support the two sides of the local convex position of the workpiece 2000 to be welded, thereby improving the uniformity of the overall force at the water cooling port of the workpiece 2000 to be welded, such as a battery tray, and further reducing the risk of deformation of the workpiece 2000 to be welded.

[0175] In some embodiments, the pressing member 120 rotates synchronously when moving vertically, so that the pressing member 120 has a first state of pressing the platen 220 and a second state of releasing the platen 220. In the first state, the pressing member 120 intersects with the longitudinal beam 111, such as in a horizontal state, and presses the platen 220; in the second state, the pressing member 120 extends longitudinally and faces the longitudinal beam 111. It can be understood here that by setting the pressing member 120 to rotate synchronously during the vertical movement, the pressing member 120 can have a first state of pressing the platen 220 and a second state of releasing the platen 220, so that the pressing member 120 can not only press the platen 220, but also adaptively avoid the robot, reduce the welding difficulty of the workpiece 2000 to be welded, and improve the welding quality.

[0176] It should be noted that Fig.13The two clamping members 120 shown in the figure are schematic diagrams of the clamping member 120 in the first state and the second state, respectively, wherein the clamping member 120 close to the slide 110 is a schematic diagram of the clamping member 120 in the second state, and the clamping member 120 away from the slide 110 is a schematic diagram of the clamping member 120 in the first state.

[0177] Depend on Fig.13 It can be seen that in the second state, the extension direction of the clamping piece 120 is consistent with the extension direction of the longitudinal beam 111 of the slide 110, and the clamping piece 120 is vertically opposite to the longitudinal beam 111 of the slide 110. In this way, the clamping piece 120 can be hidden under the longitudinal beam 111 of the slide 110, thereby controlling the clamping piece 120 to avoid the robot, avoiding the clamping piece 120 from hindering the robot's welding to a certain extent, and reducing the welding difficulty of the workpiece 2000 to be welded.

[0178] At the same time, by Fig.13 It can be seen that in the first state, the extension direction of the clamping member 120 intersects with the extension direction of the longitudinal beam 111 of the slide 110, so that the clamping member 120 can be used to clamp the pressure plate 220, thereby reducing the difficulty of clamping the workpiece 2000 to be welded, thereby improving the position stability of the workpiece 2000 to be welded, and facilitating the welding and fixing of the workpiece 2000 to be welded.

[0179] In some embodiments, in combination Fig.11 and Fig.12 As shown, the slide 110 includes two vertical columns 112 and a longitudinal beam 111. The two vertical columns 112 are arranged at intervals and are respectively movably arranged on the base 900 in the transverse direction. The longitudinal beam 111 is connected to one end of the two vertical columns 112 away from the base 900 to form the slide 110 into a gantry structure, thereby facilitating the slide 110 to be movably arranged on the base 900.

[0180] In some embodiments, in combination Fig.11 , Fig.12 and Fig.14 As shown, the clamping member 120 is a clamping plate, and a clamping block 122 is provided on the side of the clamping plate facing the workpiece 2000 to be welded. The clamping block 122 is used to clamp the workpiece 2000 to be welded. While clamping and fixing the workpiece 2000 to be welded, the contact area between the clamping member 120 and the workpiece 2000 to be welded can be reduced, thereby avoiding the clamping member 120 from crushing the workpiece 2000 to be welded to a certain extent.

[0181] Optionally, the pressing block 122 is made of copper, aluminum or other materials.

[0182] In some embodiments, in combination Fig.11 , Fig.12 and Fig.14As shown, a weight-reducing hole 121 is provided on the pressing member 120 , and the weight-reducing hole 121 is used to reduce the weight of the pressing member 120 , thereby facilitating the control of the pressing member 120 to move vertically and rotate synchronously, thereby reducing the difficulty of moving the pressing member 120 .

[0183] At the same time, the weight-reducing holes 121 can also reduce the material used for the pressing member 120 , thereby reducing the production cost of the pressing member 120 .

[0184] In some embodiments, a single workpiece 2000 to be welded is provided on the base 900, and the workpiece 2000 to be welded has two areas to be welded that are spaced apart in the transverse direction. In the first state, the clamping piece 120 extends in the transverse direction, so that the two areas to be welded can be clamped and fixed at the same time by the clamping piece 120. While reducing the difficulty of clamping the areas to be welded, the number of clamping pieces 120 set can also be reduced, thereby simplifying the structure of the slide assembly 100 and reducing the assembly difficulty and manufacturing cost of the slide assembly 100.

[0185] That is to say, the present application arranges the clamping piece 120 to rotate synchronously during the vertical movement, so that while the clamping piece 120 is used to simultaneously clamp and fix the two pressure plates 220 covering the two areas to be welded, it can also avoid the clamping piece 120 from obstructing robot welding to a certain extent.

[0186] In some embodiments, in combination Fig.11 , Fig.12 and Fig.13 As shown, the slide assembly 100 further includes a clamping member driving member 130, which is disposed on the slide 110, and the clamping member 120 is connected to the clamping member driving member 130. The clamping member driving member 130 is used to drive the clamping member 120 to move vertically and control the clamping member 120 to rotate synchronously when moving. Thus, the clamping member 120 can effectively move vertically relative to the slide 110, so that the clamping member 120 can be used to clamp the pressure plate 220 and avoid the robot, thereby reducing the control difficulty of the clamping member 120. In some embodiments, a driving member installation cavity is provided in the longitudinal beam 111 of the slide 110, and at least part of the clamping member driving member 130 is disposed in the driving member installation cavity. While the clamping member driving member 130 is disposed on the slide 110, the slide 110 can also be used to protect the clamping member driving member 130, thereby extending the service life of the clamping member driving member 130.

[0187] In some embodiments, Fig.14 As shown, the pressing member 120 is connected to the pressing member driving member 130 via the connecting pin 180, so that the pressing member 120 can swing around the connecting pin 180. In this way, when the pressing member 120 simultaneously presses and fixes the two pressing plates 220, it can accommodate the height difference between the two pressing plates 220 to improve the pressing effect of the pressing member 120 on the pressing plate 220.

[0188] In some embodiments, in combination Fig.11 and Fig.12 As shown, the pressing member 120 and the pressing member driving member 130 each include a plurality of pressing members 120, and the plurality of pressing members 120 are arranged on the slide 110 at intervals along the longitudinal direction. The pressing member driving member 130 corresponds to the pressing members 120 one by one, and the longitudinal direction intersects with the transverse direction and the vertical direction. The longitudinal direction mentioned here can be understood as Figure 1 and Figure 2 The X direction shown in the figure is the extension direction of the longitudinal beam 111. The one-to-one correspondence between the clamping member driving member 130 and the clamping member 120 means that each clamping member driving member 130 is connected to a corresponding clamping member 120, so that each clamping member 120 can be controlled by a separate clamping member driving member 130, reducing the control difficulty of the clamping member 120.

[0189] Through the above-mentioned arrangement, on the one hand, a plurality of clamping members 120 can be used to simultaneously clamp the workpiece 2000 to be welded, thereby improving the position stability of the workpiece 2000 to be welded; on the other hand, when one of the clamping members 120 is switched to the second state to avoid the workpiece 2000 to be welded, the workpiece 2000 to be welded can be clamped by other clamping members 120, thereby effectively ensuring the position stability of the workpiece 2000 to be welded during welding and reducing the difficulty of welding.

[0190] In a specific example, when the robot moves in the longitudinal direction and the pressing member 120 is disposed opposite to the robot in the longitudinal direction, the pressing member 120 can be switched to the second state in sequence to avoid the robot.

[0191] In a certain embodiment, when one of the clamping members 120 switches to the second state to avoid the robot, the other clamping members 120 are in the first state to clamp the workpiece 2000 to be welded, so that the slide assembly 100 also has the function of clamping the workpiece 2000 to be welded in the process of avoiding the robot, thereby improving the position stability of the workpiece 2000 to be welded.

[0192] In some embodiments, in combination Fig.14 and Fig.15 As shown, the pressing member driving member 130 includes a housing 131, a first output shaft 132 and a second output shaft 133. The first output shaft 132 is fixedly connected in the housing 131 and extends vertically. One end of the second output shaft 133 is connected to the first output shaft 132 through a first guide member 134, so that the second output shaft 133 can rotate synchronously when moving vertically. The other end of the second output shaft 133 extends out of the housing 131 to connect with the pressing member 120. Thus, the pressing member driving member 130 is connected with the pressing member 120, so that the pressing member 120 can be driven to move by the pressing member driving member 130, and the difficulty of moving the pressing member 120 is reduced.

[0193] At the same time, by setting the first output shaft 132 to extend vertically and connecting one end of the second output shaft 133 to the first output shaft 132 through the first guide member 134, when the second output shaft 133 is controlled to move along the extension direction of the first output shaft 132, the clamping member 120 can be controlled to move vertically, which makes it easier to use the clamping member 120 to clamp the pressure plate 220 and reduces the difficulty of controlling the clamping member 120.

[0194] In some embodiments, Fig.15 As shown, the first guide member 134 includes a guide groove 1341 and a guide ball 1342, and the guide ball 1342 is movably arranged in the guide groove 1341. One of the guide groove 1341 and the guide ball 1342 is arranged on the first output shaft 132, and the other is arranged on the second output shaft 133. The guide groove 1341 extends vertically and at least part of the guide groove 1341 extends circumferentially along the first output shaft 132 or the second output shaft 133. What is meant here is that when the guide ball 1342 is arranged on the first output shaft 132, the guide groove 1341 is arranged on the second output shaft 133 and at least part of the guide groove 1341 extends along the circumference of the second output shaft 133; correspondingly, when the guide ball 1342 is arranged on the second output shaft 133, the guide groove 1341 is arranged on the first output shaft 132 and at least part of the guide groove 1341 extends along the circumference of the first output shaft 132. In this way, when the second output shaft 133 moves relative to the first output shaft 132, it can drive the guide ball 1342 to move along the extension path of the guide groove 1341. Because the guide groove 1341 extends vertically and at least part of the guide groove 1341 extends circumferentially along the first output shaft 132 or the second output shaft 133, the guide ball 1342 and the guide groove 1341 cooperate to drive the clamping member 120 to move vertically and rotate synchronously, so as to facilitate the control of the clamping member 120 to rotate relative to the slide 110 to avoid the robot.

[0195] In some embodiments, Fig.15 As shown, the guide ball 1342 is arranged on the second output shaft 133, the guide groove 1341 is arranged on the first output shaft 132 and at least part of the guide groove 1341 extends along the circumference of the first output shaft 132, so that the guide ball 1342 and the guide groove 1341 can cooperate to drive the clamping member 120 to rotate synchronously when moving vertically, thereby reducing the difficulty of controlling the clamping member 120.

[0196] Of course, in some other embodiments, the guide ball 1342 can also be provided on the first output shaft 132, and the guide groove 1341 can be provided on the second output shaft 133 and at least part of the guide groove 1341 can extend along the circumference of the second output shaft 133. In this way, the guide ball 1342 and the guide groove 1341 can also be used to cooperate to drive the clamping member 120 to rotate synchronously when moving vertically.

[0197] In some embodiments, Fig.15 As shown, one end of the second output shaft 133 is sleeved on the outer periphery of the first output shaft 132, so that when the guide groove 1341 is provided on the first output shaft 132, the guide groove 1341 is provided on the outer peripheral wall of the first output shaft 132 and extends along the circumference of the first output shaft 132; when the guide groove 1341 is provided on the second output shaft 133, the guide groove 1341 is provided on the inner peripheral wall of the second output shaft 133 and extends along the circumference of the second output shaft 133, so as to realize the guiding cooperation between the guide groove 1341 and the guide ball 1342.

[0198] In some embodiments, the guide balls 1342 and the guide grooves 1341 each include a plurality, and the plurality of guide grooves 1341 correspond one to one with the plurality of guide balls 1342, which can increase the matching strength between the first output shaft 132 and the second output shaft 133, so that the matching of the guide balls 1342 and the guide grooves 1341 can effectively drive the clamping member 120 to rotate synchronously when moving vertically, thereby ensuring the working performance of the clamping member 120 to a certain extent.

[0199] In some embodiments, Fig.14 As shown, the first guide member 134 further includes an elastic member 1343, and the elastic member 1343 is used to drive the guide ball 1342 to move toward the guide groove 1341. The guide ball 1342 can be effectively matched in the guide groove 1341, so that the guide ball 1342 can effectively move along the extension direction of the guide groove 1341, and the guide match between the guide ball 1342 and the guide groove 1341 is achieved, so as to control the synchronous rotation of the second output shaft 133 when moving vertically, and reduce the control difficulty of the pressing member 120.

[0200] The elastic member 1343 mentioned here may be a spring, a rubber member, etc.

[0201] It should be noted that, since the present application utilizes the guide ball 1342 and the guide groove 1341 to cooperate in guiding the clamping member 120 to rotate synchronously when moving vertically, the weight of the clamping member 120 is reduced by providing a weight-reducing hole 121 on the clamping member 120, and the wear between the guide ball 1342 and the guide groove 1341 can also be reduced, thereby extending the service life of the guide ball 1342 and the guide groove 1341.

[0202] In some embodiments, in combination Fig.11 and Fig.12As shown, the slide assembly 100 further includes a buffer 140, which is disposed on the slide 110 and close to the pressing member 120. The buffer 140 is used to cooperate with the pressing member 120 for buffering when the pressing member 120 switches from the first state to the second state, so as to limit the pressing member 120 in the second state. Thus, the position of the pressing member 120 is accurate, so that the pressing member 120 can effectively switch between the first state and the second state, and when the pressing member 120 switches to the second state, it can be arranged vertically opposite to the longitudinal beam 111 of the slide 110, so as to achieve hiding of the pressing member 120 under the longitudinal beam 111 of the slide 110, thereby achieving control of the pressing member 120 to avoid the robot.

[0203] The buffer member 140 mentioned here may be composed of structures such as a buffer spring, a piston rod and a buffer head to ensure the buffering effect of the buffer member 140 .

[0204] In some embodiments, in combination Fig.11 and Fig.12 As shown, the slide assembly 100 further includes a slide driver 150 and a second guide 160. The slide driver 150 is connected to the slide 110 to drive the slide 110 to move in the lateral direction. The second guide 160 is connected to the slide 110 and the base 900. The second guide 160 is used to guide the lateral movement of the slide 110. Thus, the slide 110 is movably arranged on the base 900 in the lateral direction, so that the slide 110 can be used to press and fix the workpiece 2000 to be welded at different positions in the lateral direction, thereby improving the position stability of the workpiece 2000 to be welded during robot welding, which is conducive to improving the welding quality of the robot.

[0205] In some embodiments, in combination Fig.11 and Fig.12 As shown, the slide drive 150 includes a drive motor 151, a drive screw 152 and a drive nut 153. The drive motor 151 is arranged on the base 900, and the output end of the drive motor 151 is connected to the drive screw 152. The drive screw 152 extends in the transverse direction. The drive nut 153 is movably arranged on the drive screw 152 and the drive nut 153 is connected to the slide 110. In this way, the drive motor 151 can be used to drive the drive screw 152 to rotate. During the rotation of the drive screw 152, the drive nut 153 moves along the extension direction of the drive screw 152, that is, moves in the transverse direction, thereby driving the slide 110 to move in the transverse direction, thereby reducing the difficulty of moving the slide 110.

[0206] Among them, by arranging the drive motor 151 on the base 900, the base 900 can be used to support the drive motor 151, which can reduce the difficulty of fixing the drive motor 151 and improve the position stability of the drive motor 151, thereby ensuring the working performance of the drive motor 151 to a certain extent.

[0207] In some embodiments, in combination Fig.11 and Fig.12 As shown, one end of the driving screw rod 152 is connected to the driving motor 151, and the other end is connected to the base 900. The driving screw rod 152 is spaced apart from the base 900. While improving the position stability of the driving screw rod 152, the driving nut 153 provided on the driving screw rod 152 can also be spaced apart from the base 900, so that the driving nut 153 can effectively move along the driving screw rod 152, thereby reducing the difficulty of moving the slide 110.

[0208] In some embodiments, the driving motor 151 is a rotating motor, and the output end of the rotating motor is connected to the driving screw 152, so that the driving motor 151 can be used to drive the driving screw 152 to rotate, and then drive the driving nut 153 to move along the extension direction of the driving screw 152, so as to achieve the purpose of using the driving motor 151 to drive the slide 110 to move horizontally, thereby reducing the difficulty of moving the slide 110.

[0209] It should be noted that the above-mentioned slide drive component 150 includes a drive motor 151, a drive screw 152 and a drive nut 153 for illustration. In some other embodiments, the slide drive component 150 can also be formed in the form of a drive motor 151, a movable rack and a rotating gear, or the drive motor 151 is formed as a linear motor, and the output end of the linear motor is connected to the slide 110, so as to directly utilize the drive motor 151 to drive the slide 110 to move horizontally.

[0210] In some embodiments, in combination Fig.11 and Fig.12 As shown, the slide drive members 150 include two groups, and the two groups of slide drive members 150 are arranged at intervals along the longitudinal direction. The two groups of slide drive members 150 cooperate to drive the slide 110 to move, so that the slide 110 can effectively move in the lateral direction.

[0211] At the same time, by arranging the two sets of slide drive members 150 to be spaced apart in the longitudinal direction, the workpiece 2000 to be welded can be avoided, so that the workpiece 2000 to be welded can be effectively arranged on the base 900, thereby facilitating welding of the workpiece 2000 to be welded.

[0212] In some embodiments, in combination Fig.11 and Fig.12As shown, the second guide member 160 includes a guide rail 161 and a guide slider 162. The guide rail 161 extends laterally, and the guide slider 162 is movably arranged on the guide rail 161 and the guide slider 162 is connected to the slide 110. In this way, when the slide driving member 150 drives the slide 110 to move laterally, it can drive the guide slider 162 to move along the extension direction of the guide rail 161, thereby realizing the use of the guide rail 161 and the guide slider 162 to limit the moving direction of the slide 110, so that the slide 110 can move along a predetermined direction, which to a certain extent avoids the position deviation of the slide 110 during the movement process, improves the position accuracy of the slide 110, and is conducive to improving the working performance of the slide 110.

[0213] In some embodiments, the guide rail 161 is disposed on the base 900. On the one hand, the base 900 can be used to support the guide rail 161, thereby improving the position stability of the guide rail 161 and thus improving the working performance of the guide rail 161. On the other hand, the guide rail 161 can be used to dispose the slide 110 on the base 900, thereby reducing the difficulty of connecting the slide 110 and the base 900.

[0214] That is to say, the guide rail 161 of the present application can not only guide the movement of the slide 110 , but also enable the slide 110 to be placed on the base 900 .

[0215] In some embodiments, in combination Fig.11 and Fig.12 As shown, the second guide members 160 include two groups, and the two groups of second guide members 160 are arranged at intervals along the longitudinal direction. The two groups of second guide members 160 enable the slide 110 to move accurately in the transverse direction, thereby improving the position accuracy of the slide 110 and helping to improve the working performance of the slide 110.

[0216] At the same time, by arranging the two groups of second guide members 160 to be spaced apart in the longitudinal direction, the workpiece 2000 to be welded can be avoided, so that the workpiece 2000 to be welded can be effectively arranged on the base 900, thereby facilitating welding of the workpiece 2000 to be welded.

[0217] In some embodiments, in combination Fig.11 and Fig.12 As shown, the slide assembly 100 also includes a dust cover 170, which is mounted on the driving screw 152 and the guide rail 161, so as to utilize the dust cover 170 to protect the driving screw 152 and the guide rail 161, and to a certain extent prevent welding slag from splashing onto the driving screw 152 and the guide rail 161. While extending the service life of the driving screw 152 and the guide rail 161, the working performance of the driving screw 152 and the guide rail 161 can also be guaranteed to a certain extent.

[0218] It should be noted that Fig.10 and Fig.11Only a portion of the dust cover 170 is shown.

[0219] In some embodiments, in combination Fig.11 and Fig.12 As shown, the dust cover 170 is a telescopic dust cover. In the horizontal direction, the dust cover 170 includes two dust covers 170, which are respectively arranged on both sides of the slide 110 in the horizontal direction. One end of the dust cover 170 is fixedly connected to the slide 110, and the other end is fixedly connected to the base 900. When the slide 110 moves in the horizontal direction, it can drive one end of the dust cover 170 connected thereto to move, thereby realizing the stretching or compression of the dust cover 170, so that the dust cover 170 can effectively protect the driving screw 152 and the guide rail 161.

[0220] In some embodiments, in combination Figure 2 and Figure 3 As shown, the clamping assembly 210 includes a plurality of first clamping mechanisms 211 and a plurality of second clamping mechanisms 214. The plurality of first clamping mechanisms 211 are arranged around the periphery of the base 900 and include a first driving member 2111 and a first clamping arm 2112. The first driving member 2111 is arranged on the base 900. The base 900 has a supporting plane 910 for supporting the workpiece 2000 to be welded (the specific structure of the supporting plane 910 can be seen in Figure 4 and Figure 5 ), the axis of the first driving member 2111 is parallel to the supporting plane 910, the first clamping arm 2112 is connected to the first driving member 2111, the first driving member 2111 is used to drive the first clamping arm 2112 to rotate relative to the base 900 to clamp or release the workpiece 2000 to be welded, and multiple first clamping mechanisms 211 are used to clamp the edge of the upper cover 2200 and the edge of the pressure plate 220 of each workpiece 2000 to be welded near the periphery of the base 900. That is to say, the first driving member 2111 and the first clamping arm 2112 cooperate so that the first clamping mechanism 211 can clamp or release the upper cover 2200 or the pressure plate 220, wherein when the first clamping mechanism 211 clamps the upper cover 2200 and the pressure plate 220, the workpiece 2000 to be welded and the pressure plate 220 can be stably arranged on the base 900, so as to improve the position stability of the workpiece 2000 and the pressure plate 220 to be welded, and to a certain extent avoid the displacement of the workpiece 2000 and the pressure plate 220 when the robot welds the workpiece 2000 to be welded, thereby reducing the welding difficulty and improving the welding quality; when the first clamping mechanism 211 releases the pressure plate 220 and the upper cover 2200, on the one hand, it can facilitate the removal of the welded workpiece 2000 to be welded, and on the other hand, in order to avoid interference between the robot 600 and the first clamping arm 2112 during the welding process, the first clamping arm can be controlled to open and clamp sequentially.

[0221] It should be noted that during the actual welding process of the robot, when the first clamping arm 2112 is used to clamp the pressure plate 220 but the first clamping arm 2112 interferes with the robot, the first driving member 2111 drives the first clamping arm 2112 to rotate relative to the base 900 to release the pressure plate 220, thereby avoiding the robot and, to a certain extent, preventing the first clamping arm 2112 from hindering the robot's welding; when there is no interference, the first clamping arm 2112 is controlled to rotate relative to the base 900 and clamp the pressure plate 220, so as to achieve the purpose of fixing the pressure plate 220 and the workpiece 2000 to be welded.

[0222] That is, the first clamping arm 2112 opens to avoid the robot when the robot passes by, and then clamps the upper cover 2200 and the workpiece 2000 to be welded after the robot passes by.

[0223] It is worth noting that the present application is provided with a plurality of first clamping mechanisms 211 and a plurality of second clamping mechanisms 214, and the plurality of first clamping mechanisms 211 and the plurality of second clamping mechanisms 214 are arranged to be arranged around the periphery of the base 900. On the one hand, the plurality of first clamping mechanisms 211 and the plurality of second clamping mechanisms 214 can be used to cooperate with the pressing plate 220 and the upper cover 2200 at the same time, thereby improving the position stability of the pressing plate 220 and the workpiece 2000 to be welded. On the other hand, when one of the first clamping arms 2112 is opened when the robot passes by, the remaining first clamping arms 2112 can be used to clamp the pressing plate 220.

[0224] It is also worth noting that because the first clamping arm 2112 needs to be opened when the robot passes by and closed again after the robot passes by, based on this, the present application sets the axis of the first driving member 2111 to be parallel to the supporting plane 910, that is, the first driving member 2111 is set as a horizontal driving member, which can reduce the height of the first driving member 2111, thereby reducing the overall height of the first clamping mechanism 211. On the one hand, it avoids increasing the overall height dimension of the tooling fixture 200 due to the setting of the first clamping mechanism 211, thereby reducing the assembly difficulty of the tooling fixture 200. On the other hand, when the first driving member 2111 drives the first clamping arm 2112 to open to release the pressure plate 220 and the upper cover 2200, the overall height of the first clamping arm 2112 is reduced. At this time, the first clamping arm 2112 can be rotated at a smaller angle to avoid the robot, thereby avoiding interference between the first clamping arm 2112 and the robot when releasing the pressure plate 220 to a certain extent, reducing the difficulty of welding, and reducing the difficulty of controlling the first clamping arm 2112.

[0225] In the present application, the axis of the first driving member 2111 is set to be parallel to the supporting plane 910. While facilitating the reduction of the overall height dimension of the tooling fixture 200, it can also avoid interference with the robot when the first clamping arm 2112 opens the release pressure plate 220 to a certain extent, thereby reducing the difficulty of welding and reducing the difficulty of controlling the first clamping arm 2112.

[0226] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4 As shown, the axis of the first driving member 2111 distributed on the lateral side of the base 900 extends longitudinally, and the axis of the first driving member 2111 distributed on the longitudinal side of the base 900 extends transversely.

[0227] In some embodiments, the first driving member 2111 is a driving cylinder, which has significant advantages such as high efficiency, flexibility, reliability and strong load-bearing capacity, so that the first driving member 2111 can effectively drive the first clamping arm 2112 to rotate relative to the base 900, so as to ensure the working performance of the first clamping mechanism 211 to a certain extent.

[0228] Of course, in some other embodiments, the first driving member 2111 may also be a driving cylinder.

[0229] In some embodiments, in combination Figure 3 , Fig.16 and Fig.18 As shown, the first clamping mechanism 211 also includes a first clamping block 2113, which is arranged at the clamping end of the first clamping arm 2112 and is arranged toward the pressure plate 220, so that the first clamping block 2113 can be used to clamp the pressure plate 220. While clamping and fixing the workpiece 2000 to be welded, the contact area between the first clamping arm 2112 and the pressure plate 220 can be reduced, thereby avoiding the first clamping arm 2112 from crushing the workpiece 2000 to be welded to a certain extent.

[0230] Optionally, the first pressing block 2113 is made of copper, aluminum or other materials.

[0231] In some embodiments, in combination Figure 3 and Fig.21As shown, a plurality of second clamping mechanisms 214 are arranged around the four corners of the base 900, and are used to clamp the four corners of the bottom box 2100 of the workpiece 2000 to be welded, and include a second driving member 2141 and a second clamping arm 2142. The second driving member 2141 is arranged on the base 900, and the axis of the second driving member 2141 extends vertically and intersects with the supporting plane 910 of the base 900. The second clamping arm 2142 is connected to the second driving member 2141. The second driving member 2141 is used to drive the second clamping arm 2142 to rotate relative to the base 900 to clamp or release the corners of the bottom box 2100 of the workpiece 2000 to be welded. Among them, when multiple second clamping mechanisms 214 press the four corners of the bottom box 2100, the bottom box 2100 can be stably set on the base 900 to improve the position stability of the bottom box 2100, and to a certain extent avoid the displacement of the bottom box 2100 when the robot welds the workpiece 2000 to be welded, thereby reducing the welding difficulty and improving the welding quality; when the multiple second clamping mechanisms 214 release the four corners of the bottom box 2100, it is convenient to take out the welded workpiece 2000.

[0232] It should be noted that, in the present application, the axis of the second driving member 2141 of the second clamping mechanism 214 is set to intersect with the supporting plane 910, so that the second driving member 2141 of the second clamping mechanism 214 is formed into a vertical driving member, thereby reducing the difficulty of installing the second clamping mechanism 214, and further reducing the difficulty of assembling the tooling fixture 200.

[0233] In some embodiments, the second driving member 2141 is a driving cylinder, which has significant advantages such as high efficiency, flexibility, reliability and strong load-bearing capacity, so that the second driving member 2141 can effectively drive the second clamping arm 2142 to rotate relative to the base 900, so as to ensure the working performance of the second clamping mechanism 214 to a certain extent.

[0234] Of course, in some other embodiments, the second driving member 2141 may also be a driving cylinder.

[0235] In some embodiments, in combination Figure 3 and Fig.21 As shown, the second clamping mechanism 214 also includes a second clamping block 2145, which is arranged at the clamping end of the second clamping arm 2142, so as to facilitate using the second clamping block 2145 to clamp the corner of the bottom box 2100. While clamping and fixing the corner of the bottom box 2100, the contact area between the second clamping arm 2142 and the bottom box 2100 can be reduced, thereby avoiding the second clamping arm 2142 from crushing the corner of the bottom box 2100 to a certain extent.

[0236] Optionally, the second pressing block 2145 is made of copper, aluminum or other materials.

[0237] In some embodiments, in combination Figure 3 and Fig.21 As shown, the second clamping mechanism 214 includes a third mounting seat 2144 and a third adapter shaft 2146. The third mounting seat 2144 is provided on the base 900, and the second driving member 2141 is fixedly connected to the third mounting seat 2144. Thus, the second driving member 2141 is fixedly connected to the base 900, so that the base 900 is used to support the second driving member 2141, thereby improving the position stability of the second driving member 2141.

[0238] Alternatively, if Fig.21 As shown, the second clamping arm 2142 is rotatably connected to the third output end 2143 of the second driving member 2141 through the third adapter shaft 2146, thereby realizing the rotatable connection between the second driving member 2141 and the second clamping arm 2142, and reducing the difficulty of the rotatable connection between the second driving member 2141 and the second clamping arm 2142, making it easier to use the second driving member 2141 to drive the second clamping arm 2142 to rotate relative to the base 900, so as to achieve the purpose of using the second clamping arm 2142 to clamp or release the corner of the bottom box 2100 of the workpiece 2000 to be welded, thereby ensuring the working performance of the second clamping arm 2142 to a certain extent.

[0239] Alternatively, if Fig.21 As shown, the second clamping mechanism 214 also includes a fourth mounting seat 2147 and a third adapter 2148. The fourth mounting seat 2147 is fixedly connected to the second driving member 2141, and the middle section of the second clamping arm 2142 is rotatably connected to the third adapter 2148, so that when the second driving member 2141 drives one end of the second clamping arm 2142 to rotate, the second clamping arm 2142 can effectively rotate relative to the base 900 to ensure the working performance of the second clamping arm 2142.

[0240] In some embodiments, in combination Figure 3 , Fig.15 and Fig.18As shown, multiple first clamping mechanisms 211 include a first clamping unit 212 and a second clamping unit 213. The first clamping unit 212 is arranged at the lateral side of the base 900, and the first driving member 2111 of the first clamping unit 212 has a first output end 2121. The first output end 2121 is located on the side of the first driving member 2111 of the first clamping unit 212 facing the workpiece 2000 to be welded, and the first clamping arm 2112 of the first clamping unit 212 is rotatably connected to the first output end 2121. What is meant here is that the axis of the first driving member 2111 is parallel to the supporting plane 910, and the first output end 2121 of the first driving member 2111 of the first clamping unit 212 extends toward the workpiece 2000 to be welded, so that the first output end 2121 is arranged close to the workpiece 2000 to be welded. In this way, when the first clamping arm 2112 of the first clamping unit 212 is rotatably connected to the first output end 2121, the first clamping arm 2112 of the first clamping unit 212 can be arranged close to the workpiece 2000 to be welded, so that the first clamping arm 2112 of the first clamping unit 212 can be used to clamp the pressure plate 220, thereby reducing the difficulty of fixing the pressure plate 220.

[0241] At the same time, through the above-mentioned arrangement, when the first clamping arm 2112 rotates relative to the base 900 and releases the pressure plate 220, the rotation angle of the first clamping mechanism 211 is small, and the overall height of the first clamping mechanism 211 is relatively low, so as to effectively avoid the robot and prevent the first clamping mechanism 211 from interfering with the robot, thereby facilitating the use of the robot to weld the workpiece 2000 and reducing the difficulty of welding.

[0242] In addition, through the above-mentioned arrangement, the first driving member 2111 of the first clamping unit 212 can be arranged away from the workpiece 2000 to be welded relative to the first clamping arm 2112 of the first clamping unit 212, so that the first driving member 2111 of the first clamping unit 212 can avoid the structure on the workpiece 2000 to be welded, thereby enabling the first driving member 2111 of the first clamping unit 212 to be effectively arranged on the base 900, so as to facilitate the use of the first clamping arm 2112 of the first clamping unit 212 to clamp the workpiece 2000 to be welded.

[0243] In some embodiments, Fig.16 and Fig.17As shown, the first clamping unit 212 also includes a first adapter shaft 2126, and the first output end 2121 is rotatably connected to the first clamping arm 2112 of the first clamping unit 212 through the first adapter shaft 2126, thereby realizing the rotatable connection between the first driving member 2111 of the first clamping unit 212 and the first clamping arm 2112 of the first clamping unit 212, and reducing the difficulty of the rotatable connection between the first driving member 2111 of the first clamping unit 212 and the first clamping arm 2112 of the first clamping unit 212, so as to facilitate using the first driving member 2111 of the first clamping unit 212 to drive the first clamping arm 2112 of the first clamping unit 212 to rotate relative to the base 900, so as to achieve the purpose of using the first clamping arm 2112 of the first clamping unit 212 to clamp or release the pressure plate 220, thereby ensuring the working performance of the first clamping unit 212 to a certain extent.

[0244] For the convenience of description, the first driving member 2111 of the first pressing unit 212 is defined as a first driving cylinder, and the first pressing arm 2112 of the first pressing unit 212 is defined as a first pressing arm.

[0245] In summary, the axis of the first driving cylinder is parallel to the supporting plane 910 , and the first driving cylinder has a first output end 2121 , which is located on the side of the first driving cylinder facing the workpiece 2000 to be welded, and the first pressing arm is rotatably connected to the first output end 2121 .

[0246] In some embodiments, in combination Figure 3 , Fig.16 and Fig.17 As shown, the first pressing unit 212 includes a first mounting seat 2122, the first mounting seat 2122 is arranged on the base 900, and the first driving member 2111 and the first pressing arm 2112 of the first pressing unit 212 are both rotatably connected to the first mounting seat 2122. Here, it means that the first driving oil cylinder and the first pressing arm are both rotatably connected to the first mounting seat 2122, so that the first driving oil cylinder and the first pressing arm can both rotate relative to the first mounting seat 2122, so as to facilitate the use of the first driving oil cylinder to drive the first pressing arm to rotate relative to the base 900, so as to achieve the purpose of using the first pressing unit 212 to press or release the plate to be pressed 220.

[0247] In some embodiments, the first mounting seat 2122 is fixedly connected to the base 900 to achieve a fixed connection between the first driving cylinder and the base 900, thereby improving the connection strength between the first driving cylinder and the base 900, thereby improving the position stability of the first driving cylinder. The fixed connection between the first mounting seat 2122 and the base 900 mentioned here can be welding, bonding or bolt connection, etc.

[0248] In some embodiments, in combination Fig.16 and Fig.17As shown, the first mounting seat 2122 includes a driving member mounting seat 2123 and a clamping arm mounting seat 2124, one end of the first clamping arm is rotatably connected to the clamping arm mounting seat 2124, and the other end of the first clamping arm extends toward the workpiece 2000 to be welded, one end of the first driving cylinder is rotatably connected to the middle section of the first clamping arm through the first output end 2121, and the other end of the first driving cylinder is rotatably connected to the driving member mounting seat 2123, and at least a portion of the first driving cylinder is spaced apart from the driving member mounting seat 2123, thereby realizing that the first driving cylinder and the first clamping arm are both set to be rotatably connected to the first mounting seat 2122, thereby ensuring the working performance of the first clamping unit 212 to a certain extent.

[0249] Through the above-mentioned arrangement, in a specific embodiment, when the first driving cylinder drives the first pressing arm to rotate relative to the base 900, the first driving cylinder itself rotates relative to the driving member mounting seat 2123, so that the first driving cylinder can effectively drive the first pressing arm to rotate, thereby ensuring the working performance of the first clamping unit 212 to a certain extent.

[0250] Alternatively, if Fig.16 and Fig.17 As shown, the driving member mounting seat 2123 and the clamping arm mounting seat 2124 are arranged at intervals to form an escape space for the first clamping arm between the driving member mounting seat 2123 and the clamping arm mounting seat 2124, so that the first clamping arm can effectively rotate relative to the clamping arm mounting seat 2124.

[0251] In some embodiments, Fig.16 and Fig.17 As shown, the first clamping unit 212 also includes a first adapter 2125, which is sleeved on the other end of the first driving cylinder and rotatably connected to the driving member mounting seat 2123, thereby realizing the rotatable connection between the other end of the first driving cylinder and the driving member mounting seat 2123, reducing the difficulty of the rotatable connection between the first driving cylinder and the driving member mounting seat 2123.

[0252] Optionally, combined Figure 3 , Fig.18 and Fig.19As shown, multiple second clamping units 213 are distributed on the longitudinal side of the base 900, a part of which is used to clamp on the edge of the pressure plate 220, and the other part is used to clamp on the edge of the upper cover 2200, and multiple second clamping units 213 cross-clamp the edges of the pressure plate 220 and the edges of the upper cover 2200; the first driving member 2111 of the second clamping unit 213 has a second output end 2131, and the second output end 2131 is located on the side of the first driving member 2111 of the second clamping unit 213 that is away from the workpiece 2000 to be welded, one end of the first clamping arm 2112 of the second clamping unit 213 is rotatably connected to the second output end 2131, and the other end of the first clamping arm 2112 of the second clamping unit 213 extends in a direction close to the workpiece 2000 to be welded. This allows the first clamping arm 2112 of the second clamping unit 213 to be disposed close to the workpiece 2000 to be welded, making it easier to use the first clamping arm 2112 of the second clamping unit 213 to clamp the pressing plate 220 or the upper cover 2200 , thereby reducing the difficulty of fixing the pressing plate 220 and the workpiece 2000 to be welded.

[0253] For the convenience of description, the first driving member 2111 of the second pressing unit 213 is defined as a second driving cylinder, and the first pressing arm 2112 of the second pressing unit 213 is defined as a second pressing arm.

[0254] That is to say, the axis of the second driving cylinder is parallel to the supporting plane 910, and the second driving cylinder has a second output end 2131, and the second output end 2131 is located on the side of the second driving cylinder away from the workpiece 2000 to be welded, one end of the second pressing arm is rotatably connected to the second output end 2131, and the other end of the second pressing arm extends in a direction close to the workpiece 2000 to be welded.

[0255] It is worth emphasizing that by setting the second output end 2131 to be located on the side of the second driving cylinder facing away from the workpiece 2000 to be welded, when the second driving cylinder controls the second pressing arm to open through the second output end 2131 to release the pressing plate 220 or the upper cover 2200, it is easy to control the second pressing arm to rotate at a larger angle, reducing the difficulty of rotating the second pressing arm, so that the second pressing arm can effectively avoid the robot to avoid interference between the second pressing arm and the robot.

[0256] At the same time, since the rotation difficulty of the second pressing arm is reduced, the extension length of the second pressing arm can be adaptively increased, so that the second pressing arm can be used to press the upper cover 2200 and the bottom box 2100 of the workpiece 2000 to be welded, further ensuring the working performance of the second pressing arm, which is beneficial to improving the pressing quality of the first pressing mechanism 211.

[0257] Optionally, combined Figure 3 , Fig.18 and Fig.19As shown, an accommodating space 2132 for accommodating the workpiece 2000 to be welded is formed between the first driving member 2111 and the first pressing arm 2112 of the second pressing unit 213 . What is meant here is that the second output end 2131 is arranged to be located on the side of the second driving cylinder facing away from the workpiece 2000 to be welded, and after one end of the second pressing arm is rotatably connected to the second output end 2131 and the other end of the second pressing arm is extended in a direction close to the workpiece 2000 to be welded, a accommodating space 2132 for accommodating the workpiece 2000 to be welded is formed between the second driving cylinder and the second pressing arm. On the one hand, the accommodating space 2132 is used to avoid the second pressing arm so that the second pressing arm can be effectively rotated to clamp or release the workpiece 2000 to be welded. On the other hand, during the assembly of the second clamping unit 213, the second clamping unit 213 can be arranged close to the workpiece 2000 to be welded through the accommodating space 2132, so as to avoid, to a certain extent, excessive increase in the size of the tooling fixture 200 due to the arrangement of the second clamping unit 213, reduce the space occupied by the tooling fixture 200, and reduce the difficulty of assembling the tooling fixture 200.

[0258] In a specific example, combined with Figure 3 , Fig.18 and Fig.19 As shown, the second clamping unit 213 is arranged in the supporting plane 910. After the workpiece 2000 to be welded is fixed in place, at least a portion of the workpiece 2000 to be welded is located in the accommodating space 2132, so that at least a portion of the second driving cylinder is located below the workpiece 2000 to be welded and at least a portion of the second pressing arm is located above the workpiece 2000 to be welded. While making it convenient to use the second pressing arm to clamp the edges of the pressing plate 220 and the upper cover 2200, it can also avoid excessively increasing the size of the tooling fixture 200 in the length direction and / or width direction due to the provision of the second clamping unit 213.

[0259] In summary, the multiple first clamping mechanisms 211 of the present application include a first clamping unit 212 and a second clamping unit 213, and the first driving member 2111 of the first clamping unit 212 and the first driving member 2111 of the second clamping unit 213 are both formed as horizontal driving members. The first output end 2121 of the first clamping unit 212 is located on the side of the first driving member 2111 of the first clamping unit 212 facing the workpiece 2000 to be welded, so that the first clamping unit 212 can effectively avoid the structure on the workpiece 2000 to be welded, and the second output end 2131 of the second clamping unit 213 is located on the side of the first driving member 2111 of the second clamping unit 213 facing away from the workpiece 2000 to be welded, so that the second clamping unit 213 can accommodate part of the structure of the workpiece 2000 to be welded.

[0260] Through the above arrangement, during the assembly of the first clamping mechanism 211, the installation positions of the first clamping unit 212 and the second clamping unit 213 can be selected according to the structure of the workpiece 2000 to be welded. While ensuring the clamping effect of the first clamping mechanism 211, the flexibility of use of the first clamping mechanism 211 can also be improved.

[0261] Specifically, when the workpiece 2000 to be welded is a battery tray, a cooling channel will be provided inside the battery tray, and a water cooling port connected to the cooling channel will be provided below the workpiece 2000 to be welded, and the water cooling port protrudes downward. In order to avoid interference between the first driving member 2111 of the first clamping mechanism 211 and the protruding water cooling port or the structural member supporting the water cooling port, a first clamping unit 212 can be provided at the position corresponding to the water cooling port, so that the first driving member 2111 of the first clamping unit 212 can be provided away from the workpiece 2000 to be welded; accordingly, a second clamping unit 213 can be provided at a position not corresponding to the water cooling port, and the second clamping unit 213 is used to press on the pressure plate 220, which can not only reduce the size of the tooling fixture 200, but also ensure the clamping quality and reduce the clamping difficulty.

[0262] In some embodiments, in combination Figure 3 , Fig.18 and Fig.19 As shown, the second pressing unit 213 further includes a second mounting seat 2134, which is disposed on the base 900, and the second driving cylinder is fixedly connected to the second mounting seat 2134. Thus, the second driving cylinder is fixedly connected to the base 900, which reduces the difficulty of connecting the second driving cylinder to the base 900, thereby facilitating the use of the base 900 to support the second driving cylinder, improving the position stability of the second driving cylinder, and ensuring the working performance of the second driving cylinder.

[0263] The fixed connection here can be welding, bonding or bolt connection, etc.

[0264] In some embodiments, in combination Fig.18 , Fig.19 and Fig. 20As shown, the second clamping unit 213 also includes a second adapter shaft 2135 and a second adapter member 2137. One end of the first clamping arm 2112 of the second clamping unit 213 is rotatably connected to the second output end 2131 via the second adapter shaft 2135. The middle section of the first clamping arm 2112 of the second clamping unit 213 is also rotatably connected to the first driving member 2111 of the second clamping unit 213 via the second adapter member 2137, so as to realize the first driving member 2111 of the second clamping unit 213 and the second clamping unit 213. A rotatable connection of a clamping arm 2112 is provided, and the difficulty of the rotatable connection between the first driving member 2111 of the second clamping unit 213 and the first clamping arm 2112 of the second clamping unit 213 is reduced, so that the first driving member 2111 of the second clamping unit 213 is used to drive the first clamping arm 2112 of the second clamping unit 213 to rotate relative to the base 900, so as to achieve the purpose of clamping or releasing the pressure plate 220 or the upper cover 2200 by the second clamping unit 213, thereby ensuring the working performance of the second clamping unit 213 to a certain extent.

[0265] In some embodiments, in combination Figure 2 and Figure 3 As shown, the first clamping unit 212 and the second clamping unit 213 each include a plurality of first clamping units 212 and a plurality of second clamping units 213, and the cooperation between the plurality of first clamping units 212 and the plurality of second clamping units 213 can effectively improve the clamping effect of the clamping assembly 210, thereby improving the position stability of the workpiece 2000 to be welded and the pressure plate 220.

[0266] In some embodiments, in combination Fig.18 , Fig.19 and Fig. 20 As shown, the second clamping unit 213 further includes a third stopper 2133, which is disposed in the accommodating space 2132. The third stopper 2133 is used to abut against the first clamping arm 2112 of the second clamping unit 213 to limit the rotation angle of the first clamping arm 2112 of the second clamping unit 213 toward the workpiece 2000 to be welded. Since the first clamping arm 2112 of the second clamping unit 213 of the present application has a large rotation angle, by providing the third stopper 2133, while realizing the use of the first clamping arm 2112 of the second clamping unit 213 to clamp the pressing plate 220, the first clamping arm 2112 of the second clamping unit 213 can also be prevented from crushing the workpiece 2000 to be welded to a certain extent, thereby ensuring the service life of the workpiece 2000 to be welded.

[0267] The third position-limiting member 2133 mentioned here may be made of materials such as steel, aluminum, and copper to ensure that the third position-limiting member 2133 has a certain structural strength, thereby ensuring the limiting effect of the third position-limiting member 2133 .

[0268] In some embodiments, in combination Fig.18 , Fig.19 and Fig. 20 As shown, the second clamping unit 213 also includes a support member 2136, which is disposed in the accommodating space 2132 and fixedly connected to the second driving cylinder. The third limiting member 2133 is disposed on the support member 2136 to achieve supporting the third limiting member 2133 by utilizing the support member 2136, thereby improving the position stability of the third limiting member 2133 and ensuring the limiting effect of the third limiting member 2133.

[0269] In some embodiments, Figure 2 As shown, the tooling fixture 200 includes a hydraulic valve island box 230. The hydraulic valve island box 230 is a key equipment set in the control system responsible for regulating and controlling the flow of fluid. It can achieve precise regulation and control of the fluid flow of the driving parts (clamping part driving part 130, slide driving part 150, first driving part 2111, etc.) to ensure the working performance of the driving parts.

[0270] In some embodiments, Fig.25 , Fig.26 As shown, the pressing plate 220 is provided with a first positioning member 223 protruding upward; Figure 1 , Fig.23 , Fig.25 and Fig.26 As shown, the truss lifting device 500 includes: a truss 510, a lifting assembly 520, a stop plate 530 and a first locking assembly 540, wherein the truss 510 includes a truss mounting portion 511 and a support portion 512, and the support portion 512 supports the truss mounting portion 511; the lifting assembly 520 is arranged on the truss mounting portion 511, and the lifting assembly 520 includes a first driving assembly 521 and a lifting column 522, and the first driving assembly 521 is used to drive the lifting column 522 to move vertically; the stop plate 530 is arranged at the bottom end of the lifting column 522, and is used to stop with the pressure plate 220; the first locking assembly 540 is arranged on the stop plate 530, and the first locking assembly 540 is used to lock the first positioning member 223 and unlock the first positioning member 223.

[0271] Reference Figure 1 and Fig.23 In the above technical solution, the support portion 512 supports the truss mounting portion 511 so that there is a certain distance between the truss mounting portion 511 and the ground, and a space for placing the workpiece 2000 to be welded is formed below the truss mounting portion 511.

[0272] Reference Figure 1 , Figure 23-Figure 26As shown, in some application scenarios, above the base 900 of the truss mounting part 511, the workpiece 2000 to be welded is placed on the base 900, and the upper cover 2200 of the workpiece 2000 to be welded is placed with the pressing plate 220. After the workpiece 2000 to be welded completes the welding operation of the predetermined welding track exposed to the pressing plate 220, it is necessary to extract the pressing plate 220 on the workpiece 2000 to be welded, the first driving component 521 drives the lifting column 522 to descend, and the stop plate 530 at the bottom of the lifting column 522 descends together with the lifting column 522. As the stop plate 530 continues to descend, the stop plate 530 abuts against the pressing plate 220, and then the first locking component 540 locks the first positioning member 223, so that the pressing plate 220 is positioned on the stop plate 530, and then the first driving component 521 drives the lifting column 522 to rise, and the pressing plate 220 rises together with the lifting column 522 to be away from the workpiece 2000 to be welded.

[0273] After the workpiece 2000 to be welded is placed on the base 900, the pressing plate 220 needs to be placed on the workpiece 2000 to be welded, and the first driving component 521 drives the lifting column 522 to descend, and the pressing plate 220 positioned on the stop plate 530 descends together with the lifting column 522. After the pressing plate 220 descends to contact with the workpiece 2000 to be welded, the first locking component 540 unlocks the first positioning member 223, and then the first driving component 521 drives the lifting column 522 to rise, and the stop plate 530 rises together with the lifting column 522. Because the restriction on the first positioning member 223 has been released, when the stop plate 530 rises, the pressing plate 220 stays on the workpiece 2000 to be welded, and the stop plate 530 rises until it is far away from the pressing plate 220 to facilitate subsequent welding operations.

[0274] The truss lifting device 500 can realize automatic picking and placing of the pressing plate 220, and there is no need for the staff to use a forklift to carry the pressing plate 220, thereby improving the efficiency of picking and placing the pressing plate 220 and improving the processing efficiency of the workpiece 2000 to be welded; during the process of picking and placing the pressing plate 220, the pressing plate 220 moves along a fixed path with the lifting column 522, so that the truss lifting device 500 can place the pressing plate 220 at a preset position each time the pressing plate 220 is placed, thereby improving the position accuracy of the pressing plate 220 when it cooperates with the workpiece 2000 to be welded; when the truss lifting device 500 positions the pressing plate 220, the stop plate 530 stops against the pressing plate 220, thereby avoiding the possibility of shaking of the pressing plate 220, improving the stability of the pressing plate 220, and improving the safety of using the truss lifting device 500.

[0275] In some embodiments, the stop plate 530 is provided with a first through hole 531 for the first positioning member 223 to pass through, and the first locking assembly 540 is located on the upper side of the stop plate 530. When the first locking assembly 540 locks the first positioning member 223, it restricts the first positioning member 223 from being separated from the first through hole 531, further improving the stability of the truss lifting device 500 in grabbing the pressure plate 220.

[0276] In some specific embodiments, the support portion 512 includes a plurality of support columns, which are arranged at intervals and jointly support the truss mounting portion 511, thereby improving the stability of the truss mounting portion 511. The truss mounting portion 511 is formed as an installation platform, and a space is formed on the installation platform for the movement of the staff, thereby improving the convenience of maintenance of the truss lifting device 500.

[0277] In some embodiments, the truss 510 further includes a ladder 513 , which extends from the installation platform to the ground to facilitate workers to climb to the installation platform.

[0278] In some embodiments, the truss 510 further includes a fence 514 disposed around the installation platform to reduce the risk of workers slipping and falling, thereby improving the safety of the truss lifting device 500 .

[0279] In some embodiments, Fig.23 and Fig.24 As shown, the lifting column 522 is provided with a first slide groove 5221 , and the first slide groove 5221 extends vertically. The truss mounting portion 511 is provided with a first sliding member, and the first sliding member is arranged in the first slide groove 5221 .

[0280] The cooperation between the first sliding member and the first sliding groove 5221 limits the moving direction of the lifting column 522 , and the lifting column 522 can only move in the vertical direction, thereby ensuring the reliability of the truss lifting device 500 .

[0281] In some specific embodiments, the first sliding member may be a slider, which has a simple structure and reduces costs. In other specific embodiments, the first sliding member may also be a roller, which abuts against the inner wall of the first slide groove 5221, thereby reducing the friction between the first sliding member and the inner wall of the first slide groove 5221 and improving the smoothness of the movement of the lifting column 522. It should be understood that the first sliding member may also be other structures, which are not limited by the present invention.

[0282] In some embodiments, the first driving assembly 521 includes: a first driving motor, a gear and a rack 5211 , the gear is disposed on the output shaft of the first driving motor, the rack 5211 is disposed on the lifting column 522 , and the gear and the rack 5211 are meshed and matched.

[0283] When the first driving motor rotates forward, the driving gear rotates, and the gear drives the rack 5211 to move downward, thereby driving the lifting column 522 to descend; when the first driving motor rotates reversely, the driving gear rotates, and the gear drives the rack 5211 to move upward, thereby driving the lifting column 522 to rise.

[0284] In the embodiment of the present invention, the first driving assembly 521 has a simple structure and high transmission stability, which not only reduces the cost of the truss lifting device 500 but also improves the reliability of the truss lifting device 500.

[0285] In other embodiments, the first drive assembly 521 includes a first drive motor, a nut and a screw rod, the nut is rotatably connected to the truss mounting portion 511, the nut is threadedly connected to the screw rod, the screw rod is slidably connected to the truss mounting portion 511, and the screw rod is fixedly connected to the lifting column 522. The first drive motor is suitable for driving the nut to rotate, and the nut drives the screw rod to move to achieve the movement of the lifting column 522. It should be understood that the first drive assembly 521 can also be other structures, as long as it can drive the lifting column 522 to move up and down, and the present invention is not limited to this.

[0286] In some embodiments, the first drive motor is configured as a servo motor. When the truss lifting device 500 is suddenly powered off, the first drive motor self-locks and brakes, restricting the movement of the lifting column 522, avoiding the risk of the lifting column 522 suddenly falling, and improving the safety of the truss lifting device 500.

[0287] In some embodiments, the lifting column 522 is provided with a positioning hole, and the truss mounting portion 511 is provided with a fourth driving assembly and a positioning column, and the fourth driving assembly is used to drive the positioning column to insert into the positioning hole to limit the movement of the lifting column 522. The risk of the lifting column 522 falling suddenly is further reduced.

[0288] In some embodiments, the positioning hole is disposed at one end of the lifting column 522 close to the stop plate 530 .

[0289] Through the above technical solution, when the positioning column is inserted into the positioning hole, the lifting column 522 can be positioned away from the workpiece 2000 to be welded, so as to prevent the lifting column 522 from affecting the welding of the workpiece 2000 to be welded.

[0290] In some embodiments, there are multiple positioning holes, which are arranged along the length direction of the lifting column 522. The fourth drive group can drive the positioning column to be inserted into any positioning hole to position the lifting column 522 at different heights. This is convenient for the staff to detect the movement of the lifting column 522 when repairing the truss lifting device 500.

[0291] In some specific embodiments, the fourth driving component includes a first oil cylinder, and the positioning column is connected to the piston of the first oil cylinder. When the lifting column 522 moves to the position where the positioning hole is opposite to the positioning column, the first oil cylinder can drive the positioning column to insert into the positioning hole to realize the positioning of the lifting column 522. The first oil cylinder can also drive the positioning column to disengage from the positioning hole to release the positioning of the lifting column 522.

[0292] Reference Fig.24 and Fig.25 In some embodiments, the stop plate 530 is movably disposed on the lifting column 522 , and a third elastic member 532 is disposed between the lifting column 522 and the stop plate 530 .

[0293] After the welding operation of the workpiece 2000 to be welded is completed, the first driving assembly 521 drives the lifting column 522 to descend, and the stop plate 530 at the bottom of the lifting column 522 descends together with the lifting column 522. When the stop plate 530 contacts the pressure plate 220, the third elastic member 532 can buffer the collision between the stop plate 530 and the pressure plate 220, so as to achieve a soft landing of the stop plate 530 and avoid damage to the workpiece 2000 to be welded when the stop plate 530 descends; the workpiece 2000 to be welded is placed on the workpiece 2000 to be welded. After being installed on the fixture 2000, the first driving assembly 521 drives the lifting column 522 to descend, and the pressing plate 220 positioned on the stop plate 530 descends together with the lifting column 522. When the pressing plate 220 contacts the workpiece 2000 to be welded, the third elastic member 532 can buffer the collision between the pressing plate 220 and the workpiece 2000 to be welded, thereby achieving a soft landing of the pressing plate 220 and avoiding damage to the workpiece 2000 to be welded when the pressing plate 220 descends, thereby effectively improving the reliability of the truss lifting device 500.

[0294] In some embodiments, a third sliding member 533 is provided on the top of the stop plate 530, and the third sliding member 533 is slidably connected to the bottom of the lifting column 522. The third sliding member 533 is provided with a limiting member 534, and the limiting member 534 is suitable for stopping with the lifting column 522 to limit the third sliding member 533 from separating from the lifting column 522.

[0295] The above technical solution limits the moving direction of the stop plate 530 through the sliding connection between the third sliding member 533 and the lifting column 522, ensures the stability of the up and down movement of the stop plate 530, and avoids the risk that the first positioning member 223 cannot pass through the first through hole 531.

[0296] In some specific embodiments, the bottom end of the lifting column 522 is connected to a first plate body 5222, and the stop plate 530 is connected to a plurality of third sliding members 533, and the third sliding members 533 are configured as guide columns, and the plurality of guide columns are spaced apart and are all disposed through the first plate body 5222. The stability of the up and down movement of the stop plate 530 is further ensured by the sliding cooperation between the plurality of guide columns and the first plate body 5222.

[0297] The limiting member 534 is disposed at the top end of the guide post and extends in the radial direction of the guide post. The limiting member 534 is suitable for abutting against the top surface of the first plate body 5222 to limit the guide post from separating from the first plate body 5222 .

[0298] In the above technical solution, the structures of the limiting member 534 and the third sliding member 533 are simple, which reduces the cost of the truss lifting device 500.

[0299] Reference Fig.25 and Fig.26 In some embodiments, the first locking assembly 540 includes a second driving assembly and a first movable member 542. The second driving assembly is used to drive the first movable member 542 to switch between a first position and a second position. When the first movable member 542 is in the first position, the first movable member 542 is engaged with the first positioning member 223 to limit the first positioning member 223 from being disengaged from the first through hole 531. When the first movable member 542 is in the second position, the first movable member 542 is disengaged from the first positioning member 223.

[0300] In the embodiment of the present invention, the first locking assembly 540 has a simple structure, which reduces the cost of the truss lifting device 500.

[0301] In some specific embodiments, the upper end of the first positioning member 223 is provided with a protrusion 224 extending radially of the first positioning member 223 , and when the first movable member 542 is in the first position, at least a portion of the first movable member 542 is located between the protrusion 224 and the stop plate 530 .

[0302] By clamping the first movable member 542 between the protrusion 224 and the stop plate 530 , the movement of the protrusion 224 toward the stop plate 530 is restricted, thereby restricting the first positioning member 223 from being separated from the first through hole 531 , and fixing the pressing plate 220 on the stop plate 530 .

[0303] In some embodiments, the protrusion 224 is formed as an annular structure, and the first movable member 542 is provided with a U-shaped opening 5421 adapted to the first positioning member 223. When the first movable member 542 is in the first position, a portion of the first positioning member 223 is located in the U-shaped opening 5421, the protrusion 224 is located outside the U-shaped opening 5421, and a portion of the first movable member 542 abuts against the bottom surface of the protrusion 224.

[0304] Through the above technical solution, the contact area between the first movable member 542 and the protruding portion 224 is increased, and the reliability of the first movable member 542 locking the first positioning member 223 is further improved.

[0305] In some embodiments, the first movable member 542 is also provided with an avoidance groove 5422 for avoiding the protrusion 224. When the first movable member 542 moves relative to the first positioning member 223, the protrusion 224 can be set in the avoidance groove 5422 and move relative to the inner wall of the avoidance groove 5422. When the first movable member 542 is in the first position, the bottom wall of the avoidance groove 5422 stops against the bottom wall of the protrusion 224.

[0306] If the first movable member 542 is not provided with the avoidance groove 5422, it is necessary to reduce the overall thickness of the first movable member 542 or increase the height of the first positioning member 223. However, reducing the overall thickness of the first movable member 542 is not conducive to the strength of the first movable member 542, and increasing the height of the first positioning member 223 is likely to cause the first positioning member 223 to interfere with other mechanisms when the workpiece 2000 to be welded is installed, and is not conducive to the strength of the first positioning member 223.

[0307] In the above technical solution, by setting the avoidance groove 5422 on the first movable part 542, while ensuring the strength of the first movable part 542, the height of the first positioning part 223 can be reduced, reducing the risk of interference between the first positioning part 223 and other mechanisms and helping to ensure the strength of the first positioning part 223.

[0308] In some embodiments, the first movable member 542 is provided with a second sliding member 543 , the stop plate 530 is provided with a second sliding groove, and at least a portion of the second sliding member 543 is located in the second sliding groove.

[0309] In the above technical solution, the sliding cooperation between the second sliding member 543 and the second sliding groove realizes the sliding connection between the first movable member 542 and the stop plate 530, limits the moving direction of the first movable member 542, and improves the stability of the movement of the first movable member 542.

[0310] In some specific embodiments, the portion of the second sliding member 543 located in the second chute can be a slider, which has a simple structure and reduces costs. In other specific embodiments, the portion of the second sliding member 543 located in the second chute can also be a roller, which abuts against the inner wall of the second chute to reduce the friction between the second sliding member 543 and the inner wall of the second chute, thereby improving the smoothness of movement of the first movable member 542. It should be understood that the portion of the second sliding member 543 located in the second chute can also be other structures, and the present invention is not limited thereto.

[0311] In some embodiments, the stop plate 530 is further provided with a first mounting member 535 and a second mounting member 536, which are distributed at both ends of the second slide groove, and a retractable dust cover 537 is connected between the first mounting member 535 and the second sliding member 543, and a retractable dust cover 537 is also connected between the second mounting member 536 and the second sliding member 543. The dust cover 537 is used to shield the second slide groove to prevent foreign objects from entering the second slide groove and affecting the sliding of the second sliding member 543, thereby ensuring the smooth movement of the first movable member 542.

[0312] Because retractable dust covers 537 are provided on both sides of the second sliding member 543, no matter where the second sliding member 543 is in the second sliding groove, the dust covers 537 on both sides of the second sliding member 543 can completely cover the second sliding groove, further reducing the risk of foreign matter entering the second sliding groove.

[0313] In some specific embodiments, the first movable member 542 is provided with two second sliding members 543, and the two second sliding members 543 are distributed at both ends of the first movable member 542.

[0314] In the embodiment of the present invention, the first movable member 542 is slidably connected to the stop plate 530 via two second sliding members 543 , which further improves the stability of the movement of the first movable member 542 .

[0315] In some embodiments, the second drive assembly includes a second cylinder 541, which is disposed between two second sliding members 543. The piston of the second cylinder 541 is connected to the first movable member 542, and the reciprocating motion of the piston of the second cylinder 541 drives the first movable member 542 to switch between the first position and the second position.

[0316] In the embodiment of the present invention, the second driving assembly has a simple structure, which reduces the cost of the truss lifting device 500, and the second oil cylinder 541 is located between the two second sliding members 543, so that the first movable member 542 is subjected to uniform force as a whole, further improving the stability of the movement of the first movable member 542.

[0317] In some embodiments, the pressing plate 220 is provided with a plurality of first positioning members 223 , and a plurality of first through holes 531 are correspondingly provided, and the plurality of first through holes 531 correspond one-to-one to the plurality of first positioning members 223 .

[0318] The first movable member 542 is provided with a plurality of engaging portions, each engaging portion being used for engaging with the corresponding first positioning member 223. In other words, each engaging portion is formed with the above-mentioned U-shaped opening 5421 and avoidance groove 5422.

[0319] In the embodiment of the present invention, the truss lifting device 500 further improves the firmness of the truss lifting device 500 when grasping the pressure plate 220 by locking the multiple first positioning members 223 on the pressure plate 220, thereby reducing the risk of the pressure plate 220 suddenly falling off the truss lifting device 500.

[0320] In some embodiments, a plurality of first locking assemblies 540 are provided. In each first locking assembly 540, when the first movable member 542 is in the first position, at least a portion of the first movable member 542 is located between the two first positioning members 223, and the first movable member 542 is snap-fitted with the two first positioning members 223, that is, each first movable member 542 is at least used to snap-fit ​​with the two first positioning members 223.

[0321] In the embodiment of the present invention, a plurality of first locking assemblies 540 are provided, which further improves the firmness of the truss lifting device 500 when grasping the pressure plate 220 , and further improves the reliability of the truss lifting device 500 .

[0322] In some specific embodiments, two first positioning members 223 are respectively disposed at both ends of the length direction of the pressing plate 220, and the four first positioning members 223 are arranged in a rectangular shape. Two first locking assemblies 540 are provided, and the two first locking assemblies 540 are disposed back to back, and the two first locking assemblies 540 are respectively used to lock the two first positioning members 223.

[0323] In the embodiment of the present invention, the four first positioning members 223 are arranged in a rectangular shape, and the two first locking assemblies 540 lock the four first positioning members 223 , which effectively improves the balance of the pressing plate 220 , thereby improving the stability of the pressing plate 220 .

[0324] It should be understood that in other embodiments, the number of the first locking assemblies 540 may also be three, four, or other numbers, and the present invention is not limited thereto.

[0325] In some embodiments, the first locking assembly 540 further includes: a third driving assembly and a second movable member 545 , wherein the third driving assembly is used to drive the second movable member 545 to move so that the second movable member 545 locks the first movable member 542 .

[0326] When the first movable member 542 is in the first position and locks the first positioning member 223, the third driving member drives the second movable member 545 to move to lock the first movable member 542, thereby preventing the first movable member 542 from moving and loosening the first positioning member 223 due to external force, thereby reducing the risk of the pressure plate 220 falling off the stop plate 530.

[0327] In some embodiments, the third driving assembly is used to drive the second movable member 545 to switch between the third position and the fourth position. When the second movable member 545 is located at the third position, the second movable member 545 is separated from the first movable member 542. When the second movable member 545 is located at the fourth position, the second movable member 545 is suitable for abutting against the first movable member 542. The second movable member 545 at the third position is higher than the second movable member 545 at the fourth position.

[0328] When the truss lifting device 500 is suddenly powered off, the first movable member 542 loses the driving force of the second driving assembly, so that the first movable member 542 is at risk of being separated from the first position. At this time, the second movable member 545 can be in the fourth position under the action of its own weight to stop with the first movable member 542, limit the movement of the first movable member 542, and position the first movable member 542 in the first position, further improving the reliability of the truss lifting device 500 in grabbing the pressure plate 220.

The piston of the third oil cylinder 544 passes through the second bracket 39 to be connected with the second movable part 545.

[0331] After the welding operation of the workpiece 2000 to be welded is completed, the first driving assembly 521 drives the lifting column 522 to descend, and the stop plate 530 at the bottom of the lifting column 522 descends together with the lifting column 522, and the first positioning member 223 on the pressing plate 220 is directly opposite to the first through hole 531 on the stop plate 530. As the stop plate 530 continues to descend, the first positioning member 223 on the pressing plate 220 passes through the first through hole 531 until the stop plate 530 and the pressing plate 220 stop, and then the second oil cylinder 541 drives the first movable member 542 to move toward the first through hole 531 until the first movable member 542 is in the first position, and a portion of the first movable member 542 is clamped between the protrusion 224 and the stop plate 530 to lock the first positioning member 223, thereby positioning the pressure plate 220 on the stop plate 530, and then the third cylinder 544 drives the second movable member 545 to move downward between the first movable member 542 and the first bracket 538, and stops with the first movable member 542, restricting the first movable member 542 from moving toward the first bracket 538, thereby locking the first movable member 542 in the first position, ensuring the reliability of the truss lifting device 500 in grabbing the pressure plate 220.
