[0039] See also Figure 1 The utility model proposes a welding device 1000 for welding a protective sheet and a pole ear. The protective sheet can be made of many materials, such as ceramic, quartz, or silica gel, which is not specifically limited here.

[0040] The welding equipment 1000 includes a tab loading device (not shown), a protective sheet loading device 100, a protective sheet transfer device 200 and a welding device 300. The welding equipment 1000 has a loading station 400 and a welding station 500. The welding device 300 is located at the welding station 500, and the welding device 300 is used to weld the protective sheet and the tab located at the welding station 500. The protective sheet loading device 100 is used to transport the protective sheet to the loading station 400. The protective sheet transfer device 200 is used to transfer the protective sheet located at the loading station 400 to the welding station 500. The tab loading device is used to transport the tab to the welding station 500.

[0041] There are many ways for the tab loading device to transport the tabs. The tab loading device can transport the tabs by means of a belt, or by means of a robot, or by other means, which are not specifically limited here.

[0042] There are many ways for the protective sheet loading device 100 to transport the protective sheet. The protective sheet loading device 100 can transport the protective sheet by means of a belt, or by sliding, or by other means, which are not specifically limited here.

[0043] There are many ways for the protective sheet transfer device 200 to transport the protective sheet. The protective sheet transfer device 200 can transport the protective sheet by rotating, or by sliding, or by other ways, which are not specifically limited here.

[0044] There are many ways to move the pole ears and protective sheets out of the welding station 500 after welding. The pole ears and protective sheets after welding can be moved out of the welding station 500 through the pole ear loading station 400. The pole ears and protective sheets after welding can also be moved out of the welding station 500 by an additionally provided manipulator. The pole ears and protective sheets after welding can also be moved out of the welding station 500 by other means, which are not specifically limited here.

[0045] During the welding process of the protective sheet, the pole ear is first placed on the welding station 500 by the pole ear loading device, and then the protective sheet is transported to the loading station 400 by the protective sheet loading device 100, and then the protective sheet located at the loading station 400 is transported to the welding station 500 by the transfer device, and then the pole sheet and the protective sheet located at the welding station 500 are welded by the welding device 300, and finally the pole ear and the protective sheet are moved out of the welding station 500.

[0046] The technical solution of the utility model, its welding equipment 1000 includes a tab feeding device, a protective sheet feeding device 100, a protective sheet transfer device 200 and a welding device 300, the welding equipment 1000 has a loading station 400 and a welding station 500; the welding device 300 is located at the welding station 500, and the welding device 300 is used to weld the protective sheet and the tab located at the welding station 500; the protective sheet feeding device 100 is used to transport the protective sheet to the feeding station 400; the protective sheet transfer device 200 is used to transfer the protective sheet located at the feeding station 400 to the welding station 500; the tab feeding device is used to transport the tab to the welding station 500. In this arrangement, the protective sheet located at the loading station 400 is transported to the welding station 500 by the protective sheet transfer device 200, and the protective sheet and the pole ear are directly assembled and welded at the welding station 500, thereby avoiding the influence of the conveying movement on the assembly quality, thereby improving the production quality of the welding equipment 1000. At the same time, the protective sheet at the loading station 400 is transported to the welding station 500 by the protective sheet transfer device 200, so that the transportation direction of the protective sheet loading device 100 can be changed according to site requirements, thereby improving the universality of the welding equipment 1000, and optimizing the structure of the welding equipment 1000, so that the components in the welding equipment 1000 are more compact.

[0047] Please also read Figure 1 to Figure 2In some embodiments of the present invention, the protective sheet transport device 200 includes a stopper 210 and a rotating module 220. The stopper 210 is used to stop the protective sheet; the rotating module 220 is used to drive the stopper 210 to rotate so as to transfer the stopper 210 to the welding station 500. In this way, the protective sheet on the stopper 210 is transported to the welding station 500 by rotating, so that when the transport direction of the protective sheet feeding device 100 is changed, the angle between the protective sheet and the tab at the welding station 500 will not change, so that the transport direction of the protective sheet feeding device 100 can be changed according to the site requirements, thereby improving the universality of the welding device 1000.

[0048] There are many ways for the limiting member 210 to limit the protective sheet. The limiting member 210 can limit the protective sheet by adsorption, the limiting member 210 can limit the protective sheet by clamping, or other ways.

[0049] For details, please refer to Figure 1 to Figure 2 The protective sheet transfer device 200 further includes a vertical motion module 230, which is drivingly connected to the rotating module 220, and is used to drive the rotating module 220 and the stopper 210 to move in the vertical direction. In this way, the stopper 210 can be moved close to the tab at the welding station 500 by the vertical motion module 230, thereby improving the welding accuracy of the welding device 1000, and the stopper 210 can also be moved away from the tab at the welding station 500 by the vertical motion module 230, thereby avoiding interference between the stopper 210 and the tab during rotation.

[0050] For further information, please also refer to Figure 1 to Figure 2 , the top of the limiter 210 is provided with a bearing groove 211, and the bottom of the bearing groove 211 is penetrated by a through hole 212, and the cross section of the through hole 212 in the radial direction is smaller than the projection surface of the protective sheet in the axial direction of the through hole 212. In this way, since the cross section of the through hole 212 in the radial direction is smaller than the projection surface of the protective sheet in the axial direction of the through hole 212, the protective sheet placed in the bearing groove 211 will not fall off from the through hole 212. After the protective sheet and the tab are welded on the welding station 500, the limiter 210 is directly driven by the vertical motion module 230 to move in the direction away from the tab. The protective sheet is a flexible member and is fixedly connected to the tab, so that the protective sheet will be deformed and separated from the bearing groove 211 from the through hole 212, thereby facilitating the unloading of the protective sheet, thereby improving the production efficiency of the welding equipment 1000.

[0051] Considering that the corners of the two adjacent outer walls of the protective sheet are more prone to collision and wear, please refer to Figures 1 to 3The corners of the two adjacent groove walls of the bearing groove 211 are both concavely set to form a first protective groove 213, and the corners of the two adjacent outer peripheral walls of the protection sheet are both located in the corresponding grooves; the corners of the two adjacent hole walls of the through hole 212 are both concavely set to form a second protective groove 214.

[0052] With such arrangement, when the protection sheet is placed in the supporting groove 211, the corners of the two adjacent outer peripheral walls of the protection sheet are located in the first protection groove 213 to avoid the corners of the two adjacent outer peripheral walls of the protection sheet from colliding with the groove wall of the supporting groove 211 and causing wear, thereby protecting the protection sheet. At the same time, a second protection groove 214 is arranged in the through hole 212 to avoid the corners of the two adjacent outer peripheral walls of the protection sheet from colliding with the hole wall of the through hole 212 and causing wear when the protection sheet is separated from the accommodating groove at the through hole 212, thereby protecting the protection sheet.

[0053] It should be noted that there are many ways to place the protective sheet from the loading station 400 into the loading groove 211. The protective sheet can be poured from the loading station 400 located above the limiting member 210 into the loading groove 211. The protective sheet can be placed in the loading groove 211 from the loading station 400 by means of a robot grasping it. No specific limitation is made here.

[0054] Preferably, please also refer to Figure 1 to Figure 2 The protection sheet transfer device 200 further includes an adsorption module 240, which is located above the loading station 400. The adsorption port of the adsorption module 240 can move in the vertical direction. The adsorption module 240 is used to adsorb the protection sheet located at the loading station 400 and drive the protection sheet to move in the vertical direction. The stopper 210 is located between the adsorption module 240 and the loading station 400. In this way, the protection sheet located at the loading station 400 is adsorbed by the adsorption port of the adsorption module 240, and then moves to the top of the stopper 210 in the vertical direction through the adsorption hole of the adsorption module, and then the protection sheet is placed in the bearing groove 211. In this way, the protection sheet located below the stopper 210 can be placed in the bearing groove 211 through the adsorption module 240, thereby improving the space utilization rate of the welding equipment 1000.

[0055] Please also read Figures 1 to 4In some embodiments of the utility model, the protection sheet loading device 100 includes a protection sheet loading module 110, a transverse movement module 120 and a transport module 130, the transverse movement module 120 is located above the protection sheet loading module 110 and the transport module 130, and the transport module 130 is located between the protection sheet loading module 110 and the welding device 300; the transverse movement module 120 is used to drive the protection sheet on the protection sheet loading module 110 to be transported to the transport module 130, and the transport module 130 is used to transport the protection sheet to the loading station 400. With such arrangement, the protective sheet on the protective sheet loading module 110 is transferred to the transport module 130 through the transverse movement module 120, and then the protective sheet is transported to the loading station 400 through the transport module 130. This can avoid interference between the transfer device and the protective sheet loading module 110, and at the same time, can make full use of the space between the protective sheet loading module 110 and the welding device 300 to make the components in the welding equipment 1000 more compact.

[0056] Specifically, the transport module 130 includes a guide rail 131 and a transport jig 132. The guide rail 131 is provided with a plug-in groove 131a. The transport jig 132 is provided with a plug-in convex portion 132a. When the transport jig 132 is located at the loading station 400, the plug-in convex portion 132a is plugged and matched with the plug-in groove 131a. In this way, the plug-in convex portion 132a and the plug-in groove 131a are matched to limit the transport jig 132, so as to ensure that the transport jig 132 transports the protective sheet to the loading station 400, thereby ensuring that the transfer device can accurately transfer the protective sheet from the loading station 400 to the welding station 500.

[0057] Please also read Figures 1 to 5 In some embodiments of the present invention, the welding device 1000 further includes a suction device 600, and the suction port of the suction device 600 faces the welding station 500. In this way, the suction device 600 can remove dust generated during welding to avoid the dust from affecting welding, thereby improving the welding quality of the welding device 1000.

[0058] Furthermore, the suction device 600 includes a suction module 610, an upper cover 620, a lower cover 630 and a driving member (not shown in the figure); the outer peripheral wall of the upper cover 620 is penetrated with a mounting hole 621, and the suction port of the suction module 610 is sealed and installed in the mounting hole 621; the upper cover 620 is provided with a first avoidance hole 622, and the lower cover 630 is provided with a second avoidance hole 631; the driving member is drivingly connected to the lower cover 630 to drive the lower cover 630 to move toward the upper cover 620, and when the upper cover 620 and the lower cover 630 are abutted, a suction chamber is formed; the welding head of the welding device 300 extends into the suction chamber through the first avoidance hole 622, and the placement member of the welding device 300 extends into the suction chamber through the second avoidance hole 631.

[0059] In this way, the suction chamber formed by the upper cover 620 and the lower cover 630 can prevent the dust generated during the welding process from exceeding the suction range of the suction module 610, thereby ensuring that the suction module 610 can fully remove the dust generated during the welding process, thereby improving the welding quality of the welding equipment 1000.

[0060] It should be noted that the cavity wall of the suction cavity formed by the upper cover 620 and the lower cover 630 is provided with a third avoidance hole for the transfer device to extend into. There are many ways to form the third avoidance hole. For example, the third avoidance hole is formed by a groove formed by the surface of the upper cover 620 facing the lower cover 630 and the lower cover 630; for another example, an outer peripheral wall of the lower cover 630 is penetrated to form an installation channel. The suction device 600 also includes a fixing part, which is fixedly installed on the welding device 300 and located in the installation channel. Both sides of the fixing part are respectively abutted against the wall of the installation channel. The lower cover 630 can move in the vertical direction relative to the fixing part. The lower cover 630, the fixing part and the upper cover 620 are arranged to form the third avoidance hole, which are not listed one by one here.
