[0002] In the traditional field of hardware terminal welding, especially the welding process involving key components such as current collectors and tabs, there has long been a dual challenge of efficiency and quality. At present, the mainstream production method still relies on manual operation combined with fixtures to complete the welding of individual bulk materials (current collectors + tabs). In today's rapidly developing manufacturing environment, this traditional model has gradually exposed many insurmountable drawbacks.

[0003] Traditional manual welding requires operators to individually pick up current collectors and tabs, precisely place them in a fixture, and then perform the welding operation. Each step requires manual intervention, making the process tedious and extremely slow, with speed severely limited by the operator's skill level. The quality of manual welding largely depends on the operator's skill and experience. Differences in skill levels among operators, as well as fatigue experienced by the same operator after prolonged work, can lead to fluctuations in welding quality. Therefore, an automated current collector welding device is needed to address these issues. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an automatic welding equipment for current collectors, which aims to solve the problem that in the prior art, when welding current collectors to tabs, manual welding is used, which not only results in low production efficiency but also fails to guarantee welding quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic welding device for current collectors is used to weld electrode tabs to current collector strips. The device includes a frame, a fixed base plate is fixedly connected to the top of the frame, and a pre-welding strip guide and a post-welding strip guide are sequentially arranged above the fixed base plate along a straight direction, forming a welding zone between the pre-welding strip guide and the post-welding strip guide.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention starts by using a vibratory feeder to feed electrodes in an orderly manner to an electrode support platform at its discharge end. A visual sorter located on the electrode support platform visually inspects the electrodes, selecting those that meet quality requirements and welding positions, and rejecting unqualified electrodes. The electrode transfer mechanism then moves the selected qualified electrodes to the welding position of the current collector strip. At this time, the current collector strip is in the correct position and posture under the action of the pre-weld strip guide and the post-weld strip guide.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example: Please refer to Figures 1-6 This embodiment provides an automatic welding device for current collectors. This device is used to weld tabs to current collector strips 1. The current collector strip 1 is formed by connecting multiple current collectors together. One end of the current collector strip 1 is wound and loaded onto a feeding tray, and the other end is wound onto a receiving tray. The automatic welding device includes a frame 2. A fixed base plate 3 is fixedly connected to the top of the frame 2. The fixed base plate 3 is fixed to the frame 2 by bolts. A pre-welding strip guide 4 and a post-welding strip guide 5 are sequentially arranged along a straight line above the fixed base plate 3. The current collector strip 1 passes through the pre-welding strip guide 4 and the post-welding strip guide 5 and is guided to the correct position. A welding zone is formed between the pre-welding strip guide 4 and the post-welding strip guide 5. A resistance welding machine 9 is also installed on the top of the fixed base plate 3. The resistance welding machine 9 is bolted to the fixed base plate 3. A welding station 10 is provided on the top of the frame 2, and a welding rod 11 is provided on the welding station 10. The welding rod 11 is located in the welding area. The resistance welding machine 9, the welding station 10 and the welding rod 11 are all existing technologies and will not be described in detail here. The top of the frame 2 is also equipped with a tab feeding vibratory feeder 7, a tab support platform 8 and a vision sorter 6. The tab feeding vibratory feeder 7, the tab support platform 8 and the vision sorter 6 are all bolted to the frame 2. The tab support platform 8 is located at the discharge end of the tab feeding vibratory feeder 7 and the vision sorter 6 is located at the tab support platform 8. The tab feeding vibratory feeder 7, the tab support platform 8 and the vision sorter 6 are all existing technologies and will not be described in detail here. A tab transfer mechanism 13 is provided on the top of the fixed base plate 3 between the vision sorter 6 and the collector sheet material belt 1. A material belt pulling mechanism 14 is also installed on the top of the fixed base plate 3. The material belt pulling mechanism 14 is used to drive the collector sheet material belt 1 to move.

[0020] Specifically, the electrode feeding vibratory feeder 7 starts working, orderly conveying the electrodes in the feeder 7 to the electrode bearing platform 8 at its discharge end. The visual sorter 6 located at the electrode bearing platform 8 performs visual inspection on the electrodes, selecting electrodes that meet the quality requirements and welding positions, and rejecting unqualified electrodes. The electrode transfer mechanism 13 operates, transferring the selected qualified electrodes to the welding position of the current collector strip 1. At this time, the current collector strip 1 is guided by the pre-welding strip guide 4 and the post-welding strip guide 5. With the resistance welding machine 9 in the correct position and posture, it is ready to weld. The welding rod 11 on its welding station 10 is aligned with the welding position of the current collector strip 1 with the electrode tab placed. The resistance welding machine 9 is started, and the welding rod 11 welds the electrode tab and the current collector strip 1 together, firmly connecting the two together. After the welding is completed, the strip pulling mechanism 14 is activated, which moves the current collector strip 1 with the electrode tab already welded a certain distance, so that the next current collector to be welded on the current collector strip 1 is moved to the welding area, ready for the next welding cycle.

[0021] In this embodiment, as Figure 6 As shown, the electrode transfer mechanism 13 includes a detection table fixing plate 1306 fixedly connected to the top of the fixed base plate 3. The detection table fixing plate 1306 is installed on the fixed base plate 3 by bolts. A detection table 1307 is fixedly connected to the top of the detection table fixing plate 1306. The detection table 1307 is installed on the detection table fixing plate 1306 by bolts. An electrode positioning groove is provided on the top of the detection table 1307. The vision selector 6 is used to transfer the electrode in the electrode carrier 8 to the electrode positioning groove of the detection table 1307. The vision selector 6 selects a suitable electrode and moves it into the electrode positioning groove of the detection table 1307. The electrode positioning groove can provide a precise placement space for the electrode. When the electrode falls into the electrode positioning groove, its position and posture can be accurately fixed. Compared with manual placement or other simple transfer methods, it greatly improves the positioning accuracy of the electrode, ensuring that the electrode can accurately dock with the current collector strip 1 during welding, thereby improving the welding quality and reducing the defect rate caused by welding deviation.

[0022] In this embodiment, as Figure 1 and Figure 6As shown, the electrode transfer mechanism 13 also includes a slide plate 1301 fixedly connected to the top of the fixed base plate 3. The slide plate 1301 is bolted to the fixed base plate 3. A first electric slide rail 1302 is mounted on the slide plate 1301 and bolted to the slide plate 1301. A first cylinder 1303 is fixedly connected to the slide base of the first electric slide rail 1302 and bolted to the slide base of the first electric slide rail 1302. The output end of the first cylinder 1303 faces downward and is fixed. A suction nozzle fixing plate 1304 is connected and bolted to the output end of the first cylinder 1303. A suction nozzle 1305 corresponding to the position of the electrode positioning groove is fixedly connected to the suction nozzle fixing plate 1304. The suction nozzle 1305 is detachably mounted on the suction nozzle fixing plate 1304 for easy replacement of damaged suction nozzles. The suction nozzle 1305 is connected to a vacuum adsorption device, which is existing technology and will not be described in detail here. When the first electric slide rail 1302 is activated, its slide block drives the first cylinder 1303 to move along the slide table. Plate 1301 moves horizontally, causing nozzle 1305 to move to the tab positioning groove on the testing platform 1307. The first cylinder 1303 operates, its output end extending downwards to push nozzle fixing plate 1304 and nozzle 1305 downwards, causing nozzle 1305 to gradually approach the tab on the tab support platform. Once nozzle 1305 contacts the tab, the vacuum adsorption device is activated to create negative pressure on nozzle 1305, adsorbing and fixing the tab onto nozzle 1305. The output end of the first cylinder 1303 retracts upwards, driving the nozzle fixing plate 1304 and the adsorbed tab... The suction nozzle 1305 moves upward, lifting the electrode from the testing table 1307. The first electric slide rail 1302 starts again, and its slide seat drives the first cylinder 1303, the suction nozzle fixing plate 1304, and the suction nozzle 1305 with the electrode adsorbed in the horizontal direction, transferring the electrode to the welding area of ​​the current collector strip 1. The output end of the first cylinder 1303 extends downward again, pushing the suction nozzle 1305 and the electrode downward, so that the electrode falls accurately onto the current collector strip 1. The vacuum adsorption device is turned off, releasing the adsorption force of the suction nozzle 1305 on the electrode, completing the electrode transfer process.

[0023] In this embodiment, as Figure 2 and Figure 4As shown, a positioning element 12 is provided at the top of the fixed base plate 3, located in the welding area. The positioning element 12 includes a positioning base 1201 fixedly connected to the top of the fixed base plate 3. The positioning base 1201 is installed on the fixed base plate 3 by screws. The top of the positioning base 1201 is provided with a strip positioning block 1202 for positioning the current collector strip 1 and an electrode positioning post 1203 for positioning the electrode tab. The strip positioning block 1202 and the electrode positioning post 1203 are integrally formed with the positioning base 1201 or can be detachably assembled. When the current collector strip 1 arrives at the welding area, the strip positioning block 1202 plays a role. Because the strip positioning block 1202 has a specific shape and size, it matches the edge or specific part of the current collector strip 1. The current collector strip 1 will contact the strip positioning block 1202 during the movement. Under the blocking and guiding action of the strip positioning block 1202, the current collector strip 1... The wafer strip 1 is accurately positioned in the predetermined position within the welding area, ensuring its horizontal positional accuracy. After being selected and transferred at the front end, the electrode tab is moved to the position above the corresponding current collector strip 1 above the welding area where the electrode tab needs to be welded. When the electrode tab descends to prepare for welding with the current collector strip 1, the electrode tab positioning post 1203 begins to function. The shape and position of the electrode tab positioning post 1203 are precisely designed according to the shape of the electrode tab and the welding position requirements. During the descent of the electrode tab, the electrode tab will contact the electrode tab positioning post 1203, which will insert into a specific hole in the electrode tab or fit against the edge of the electrode tab, thereby accurately positioning the electrode tab in both the vertical and horizontal directions. This ensures that the electrode tab is accurately placed in the predetermined welding position of the current collector strip 1, improving the quality consistency of the welded products and reducing the generation of defective welded products.

[0024] In this embodiment, as Figure 2 and Figure 5As shown, a longitudinal adjustment mechanism 15 is provided between the pre-weld strip guide 4 and the post-weld strip guide 5 and the fixed base plate 3. The longitudinal adjustment mechanism 15 includes a third cylinder 1501 fixedly connected to the top of the fixed base plate 3. The output end of the third cylinder 1501 faces upward and is fixedly connected to a connecting plate 1502. The pre-weld strip guide 4 and the post-weld strip guide 5 are fixedly connected to the connecting plate 1502. Support plates 1503 are symmetrically fixedly connected to the top of the fixed base plate 3 on both sides of the third cylinder 1501. A guide rail 1504 is fixedly connected longitudinally to the side of the support plate 1503 near the connecting plate 1502. A ball bearing that slides with the guide rail 1504 is fixedly connected to the connecting plate 1502. Before the equipment starts, the third cylinder 1501 is in a retracted state. The pre-welding strip guide 4 and the post-welding strip guide 5 are in the initial set position. The connecting plate 1502 slides with the guide rail 1504 on the support plate 1503 through the ball slide 1505 to ensure accurate vertical movement guidance. At this time, the positioning component 12 can position the current collector strip 1 and the electrode tab. After welding is completed, the third cylinder 1501 drives the connecting plate 1502 to move the pre-welding strip guide 4 and the post-welding strip guide 5 upward, so that the current collector strip 1 and the welded electrode tab are separated from the positioning component 12, avoiding obstruction to the subsequent pulling movement of the current collector strip 1.

[0025] In this embodiment, as Figure 2 and Figure 3 As shown, the material pulling mechanism 14 includes a back plate 1401 fixedly connected to the top of the fixed base plate 3. A second electric slide rail 1402 is installed on the back plate 1401. A second cylinder 1403 is fixedly connected to the slide of the second electric slide rail 1402. The output end of the second cylinder 1403 faces downward and is fixedly connected to a pulling rod 1404 corresponding to the position of the collector sheet material strip 1. The action of the second cylinder 1403 drives the pulling rod 1404 to descend. The pulling rod 1404 will cooperate with a specific hole on the collector sheet material strip 1. The action of the second electric slide rail 1402 drives the pulling rod 1404 and the collector sheet material strip 1 to move horizontally together, thereby pulling the collector sheet material strip 1 forward along the set path, placing the unwelded collector sheet on the collector sheet material strip 1 into the welding area. Then the second cylinder 1403 and the second electric slide rail 1402 are reset, preparing for the next material pulling.

[0026] Working principle: During use, the collector strip 1 is conveyed into the pre-welding strip guide 4 and the post-welding strip guide 5. The electrode feeding vibratory feeder 7 starts working, conveying the electrodes in the vibratory feeder 7 to the electrode bearing platform 8 at its discharge end. The visual sorter 6 located at the electrode bearing platform 8 performs visual inspection on the electrodes, selecting electrodes that meet the quality requirements and welding positions, and rejecting unqualified electrodes. The selected electrodes are placed in the electrode positioning groove of the inspection table 1307. The electrode positioning groove can provide a precise placement space for the electrodes. The first electric slide rail 1302 is activated, and its slide seat drives the first cylinder 1303 to move horizontally along the slide table fixing plate 1301, so that the suction nozzle 1 305 moves to the tab positioning groove on the testing table 1307. The first cylinder 1303 actuates, pushing the nozzle fixing plate 1304 and the nozzle 1305 downwards, causing the nozzle 1305 to gradually approach the tab on the tab support platform. When the nozzle 1305 contacts the tab, the vacuum adsorption device is activated to create negative pressure on the nozzle 1305, adsorbing and fixing the tab onto the nozzle 1305. The first cylinder 1303 resets, driving the nozzle fixing plate 1304 and the nozzle 1305 with the adsorbed tab upwards, lifting the tab from the testing table 1307. The first electric slide rail 1302 is activated again, and its slide seat drives the first cylinder 1303, the nozzle fixing plate 1304, and the nozzle 1305 with the adsorbed tab in the horizontal direction. The electrode is moved to the welding area of ​​the current collector strip 1. The output end of the first cylinder 1303 extends downward again, pushing the suction nozzle 1305 and the electrode downward so that the electrode falls accurately onto the current collector strip 1. The vacuum adsorption device is turned off, releasing the adsorption force of the suction nozzle 1305 on the electrode. The electrode is placed on the current collector strip 1 in the welding area, and the current collector strip 1 is positioned by the strip positioning block 1202 in the positioning component 12 and the electrode positioning post 1203 positions the electrode, ensuring that the electrode is accurately placed in the predetermined welding position of the current collector strip 1, improving the quality consistency of the welded products. Then the resistance welding machine 9 is started, and the welding rod 11 welds the electrode and the current collector strip 1 together, firmly connecting the two together. After the connection is completed, the third cylinder 1501 drives the connecting plate 1502 to move the pre-welding strip guide 4 and the post-welding strip guide 5 upward, so that the current collector strip 1 and the welded electrode tabs are separated from the positioning part 12. The second cylinder 1403 drives the pull rod 1404 to descend. The pull rod 1404 will cooperate with a specific hole on the current collector strip 1. The second electric slide rail 1402 drives the pull rod 1404 and the current collector strip 1 to move horizontally together, thereby pulling the current collector strip 1 forward along the set path, placing the unwelded current collectors on the current collector strip 1 into the welding area. Through the above steps, automated production is achieved, which improves the welding efficiency and quality stability and reduces labor costs.

[0027] The terms "installation," "setup," "equipped with," "connection," and "fixed connection" used in this application should be interpreted broadly. For example, they can refer to bolted connections, welded fixation, or integral structures; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
