Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, and in particular to welding and processing equipment for capacitor-type lithium-ion batteries. Background Technology

[0002] Capacitor-type lithium-ion batteries are energy storage devices that combine the high energy density of lithium-ion batteries with the high power density of supercapacitors. Through special electrode materials and structural design, they achieve rapid charging and discharging and long cycle life, and are widely used in fields that require efficient energy storage and release, such as new energy vehicles and smart grids.

[0003] The processing of capacitive lithium-ion batteries includes electrode preparation, cell assembly, formation and testing, packaging and application adaptation. In the electrode processing stage, the positive and negative electrode sheets after slitting need to be welded with tabs. Copper tabs are welded to the negative electrode and aluminum tabs are welded to the positive electrode. It is necessary to ensure that the connection between the tabs and the electrode sheets is firm and the contact resistance is low, so as to avoid local heating or breakage during charging and discharging due to poor welding, which would affect the battery performance.

[0004] In actual welding, due to slight tolerance differences in cell size, positional shifts and shaking may occur when the welding gun makes spot welding contact with the cells, resulting in incomplete welds or welding deviations, which affect the welding formation effect of capacitive lithium-ion batteries. Utility Model Content

[0045] To address the issue of displacement and shaking of capacitive lithium-ion batteries during welding, as mentioned in the background section, this invention provides a welding processing device for capacitive lithium-ion batteries, such as... Figures 1 to 5 As shown, the device includes a workbench 1, with a support rod 11 fixedly connected to the top of the workbench 1; a first slider 12 is sleeved on the outside of the support rod 11; an electric actuator 13 is fixedly connected to the bottom of the first slider 12; a welding head 14 is provided at the bottom of the electric actuator 13; a support block 15 is fixedly connected to the top of the workbench 1; a mating block 18 is slidably disposed on the top of the support block 15; both the mating block 18 and the support block 15 have round holes 19 inside; a screw 16 is threadedly connected inside the round hole 19; a nut 17 is fixedly connected to the side wall of the support block 15; the nut 17 and the screw 16 are correspondingly arranged; a placement box 101 is fixedly connected to the top of the workbench 1; a battery is placed in the placement box. Inside 101, the screw 16 can then be rotated. The screw 16 will rotate inside the round hole 19. When the screw 16 rotates, the mating block 18 will be driven by the screw 16 to start moving. When the mating block 18 moves, the battery placed inside the placement box 101 will be clamped on both sides by the mating block 18. After the battery is clamped on both sides by the mating block 18, the welding head 14 can be started. Then, the welding head 14 can be moved by sliding the first slider 12 to perform the welding work on the battery. By adding the mating block 18, the battery can be fixed before welding, reducing the shaking and displacement of the battery due to different sizes during welding.

[0046] In order to achieve the movement of the welding head 14 by the device, in another embodiment of this utility model, such as Figure 1 and Figure 2As shown, a support plate 21 is fixedly connected to the bottom of the electric push rod 13; a rotating seat 22 is fixedly connected to the bottom of the support plate 21; a first rotating shaft 2 is fixedly connected inside the rotating seat 22; the welding head 14 is rotatably connected to the outside of the first rotating shaft 2; when the first slider 12 drives the welding head 14 to slide, the welding head 14 can be rotated at this time, and then the welding head 14 will rotate outside the first rotating shaft 2. At this time, the welding head 14 can be rotated outside the first rotating shaft 2 to complete the multi-point welding of the battery by the welding head 14; by adding the first rotating shaft 2, the welding head 14 can be rotated, which allows the welding head 14 to process various parts of the battery and reduces the situation where the welding head 14 cannot weld the edge of the battery and has a dead angle displacement.

[0047] In order to achieve the cleaning function of fan 3 on workbench 1, in another embodiment of this utility model, such as Figure 2 and Figure 3 As shown, a second slider 31 is sleeved on the outside of the support rod 11; a second rotating shaft 34 is fixedly connected to the bottom of the second slider 31; a base plate 32 is fixedly connected to the bottom of the second rotating shaft 34; a motor 33 is fixedly connected to the side wall of the base plate 32; a fan 3 is fixedly connected to the output end of the motor 33; before the battery is welded by the welding head 14, the motor 33 can be started, and then the motor 33 will drive the fan 3 to rotate. At this time, the second slider 31 can be slid to control the direction of the air blown by the fan 3. At the same time, the base plate 32 can be rotated, and the base plate 32 will drive the second rotating shaft 34 to rotate. At this time, the fan 3 can complete the air blowing and cleaning work of different displacements; by adding the fan 3, the dust and debris on the surface of the battery can be removed before the battery is processed and welded, reducing the accumulation of dust and debris on the outside of the battery and improving the accuracy of the welding head 14 in welding the battery.

[0048] In another embodiment of this invention, to collect welding slag from the surface of workbench 1, such as... Figure 3 As shown, the placement box 101 has multiple chip outlets 41 inside; a connecting rod 42 is fixedly connected to the bottom of the workbench 1; a chip collection box 4 is fixedly connected to the bottom of the connecting rod 42; when the fan 3 blows air to clean the battery, the dust and impurities on the battery will be blown off by the fan 3 and finally fall into the placement box 101. Then, the debris will fall out from the chip outlets 41 and then fall into the chip collection box 4, where the chip collection box 4 collects the dust and debris. By adding the chip collection box 4, the dust and debris attached to the battery can be collected, reducing the situation where the dust and debris are blown off by the fan 3 and adsorbed on the surface of the workbench 1, thus improving the overall cleanliness of the workbench 1.

[0049] In order to achieve the cooling effect on the placement box 101, in another embodiment of this utility model, such as Figure 3As shown, a heat dissipation fin 5 is fixed to the side wall of the placement box 101; the heat dissipation fin 5 and the placement box 101 are correspondingly arranged; when the battery is welded inside the placement box 101 by the welding head 14, a high temperature will be generated inside the placement box 101. At this time, the heat dissipation fin 5 can be activated, and then the heat dissipation fin 5 will quickly cool down the outer wall of the placement box 101; by adding the heat dissipation fin 5, the surface of the placement box 101 can be quickly cooled down, which facilitates the subsequent processing of the battery inside the placement box 101 and can cool down the placement box 101 as quickly as possible.

[0050] To reduce surface defects after battery welding, in another embodiment of this invention, such as... Figure 4 and Figure 5 As shown, a storage tank 61 is fixedly connected to the top of the workbench 1; a placement plate 63 is fixedly connected to the top of the workbench 1; a cleaning sponge 6 is fixedly connected to the top of the placement plate 63; and a discharge pipe 62 is fixedly connected to the side wall of the storage tank 61. After the battery is welded by the welding head 14, cleaning fluid can be injected into the storage tank 61, and then the cleaning fluid can be sprayed onto the surface of the cleaning sponge 6 through the discharge pipe 62. At this time, the welded battery can be placed on the top of the cleaning sponge 6, and the battery can be slid on the surface of the cleaning sponge 6 to clean the battery welding points. By adding the cleaning sponge 6, residual flux on the battery surface can be removed, as well as metal debris and particles, which improves the reliability of welding and reduces subsequent corrosion of the battery.

[0051] To reduce the damage to the battery caused by the screw 16, in another embodiment of this utility model, such as Figure 4 As shown, a rubber pad 7 is fixed to the end of the screw 16; the rubber pad 7 and the screw 16 are correspondingly arranged; when the screw 16 contacts the battery, the rubber pad 7 will preferentially contact the battery, and the rubber pad 7 can increase the contact area with the battery; by adding the rubber pad 7, the screw 16 can be less likely to clamp the battery for a long time when the battery is clamped, thus reducing the possibility of damage to both sides of the battery.

[0052] To reduce the occurrence of solder flying out of the solder head 14, in another embodiment of this utility model, such as Figure 5 As shown, a dust cover 8 is provided on the outer wall of the welding head 14; the dust cover 8 and the welding head 14 are correspondingly arranged; when the welding head 14 welds the battery, some solder will fly out. When the solder flies out, the dust cover 8 will block the solder and finally fall into the placement box 101; by adding the dust cover 8, the solder can be blocked, reducing the situation where the solder does not fall into the placement box 101 and is inconvenient to clean later.

[0053] To improve the convenience of the device for the second slider 31, in another embodiment of this utility model, such as Figure 3 As shown, the first slider 12 and the second slider 31 are damped. By making the first slider 12 and the second slider 31 damped, the first slider 12 and the second slider 31 can stop when released, reducing the occurrence of excessively fast sliding and inconvenient positioning.

[0054] To improve the practicality of the discharge pipe 62, in another embodiment of this utility model, such as... Figure 5 As shown, the discharge pipe 62 is movable; by making the discharge pipe 62 movable, when it is necessary to clean the surface of the workbench 1, water can be injected into the storage tank 61, and then water will spray out from the discharge pipe 62. At this time, the discharge pipe 62 can be pulled to clean the entire workbench 1.

[0055] Working principle: The battery is placed inside the placement box 101. Then, the screw 16 is rotated, causing it to rotate within the circular hole 19. As the screw 16 rotates, the mating block 18 is driven to move. During this movement, the battery placed inside the placement box 101 is clamped on both sides by the mating block 18. After the battery is clamped by the mating block 18, the welding head 14 can be activated. The welding head 14 can then be moved by sliding the first slider 12 to perform the welding work on the battery. When the welding head 14 slides, it can be rotated, causing it to rotate outside the first rotating shaft 2. This rotation allows for multi-point welding of the battery. Before the battery is welded, the motor 33 can be started, driving the fan 3 to rotate. The direction of airflow from the fan 3 can be controlled by sliding the second slider 31. Simultaneously, the base plate 32 can be rotated, causing the second rotating shaft 34 to rotate, allowing the fan 3 to blow air at different positions. During the cleaning process, when fan 3 blows air onto the battery, dust and impurities on the battery are blown away and fall into the placement box 101. Debris then falls from the debris outlet 41 and into the debris collection box 4, where it collects the dust and debris. When the battery is being welded inside the placement box 101 by the welding head 14, the interior of the placement box 101 generates a high temperature. At this point, the heat sink 5 is activated, rapidly cooling the outer wall of the placement box 101. After the battery is successfully welded by the welding head 14, the heat sink 5 can be activated. Cleaning fluid is injected into the storage tank 61, and then sprayed onto the surface of the cleaning sponge 6 through the discharge pipe 62. At this time, the battery after welding can be placed on top of the cleaning sponge 6 and slid on the surface of the cleaning sponge 6 to clean the battery welding points. When the screw 16 contacts the battery, the rubber pad 7 will contact the battery first. The rubber pad 7 can increase the contact area with the battery. When the welding head 14 welds the battery, some solder will fly out. When the solder flies out, the dust cover 8 will block the solder and finally fall into the placement box 101.
