Description

Technical Field

[0001] This disclosure relates to the field of battery electrode manufacturing, and in particular to an electrode welding apparatus and electrode welding equipment. Background Technology

[0002] Currently, with the continuous development of new energy, the welding process of battery electrodes is particularly important for battery production, which has led to the widespread application of metal welding technology in the welding process of battery electrodes.

[0003] However, in existing technologies, most ceramic welding seats in equipment are made of metal. When the guide rollers in the equipment transport the electrode to the metal-ceramic welding seat, the battery electrode is welded by controlling the ultrasonic welding head. When the ultrasonic welding head acts on the metal-ceramic welding seat for a long time, due to the characteristics of the metal material, the metal-ceramic welding seat will absorb a lot of heat energy during the welding process, causing local overheating of the welding area and the electrode. As a result, when a new electrode is transported to the metal-ceramic welding seat for welding, the temperature of the ceramic welding seat rises, which can cause over-welding of the battery electrode, thus affecting the quality of the electrode welding. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an electrode welding device and electrode welding equipment with a welding seat that has a good welding effect.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] An electrode welding device includes a base, a lifting assembly, an electrode welding assembly, and a conveying roller assembly. The conveying roller assembly is used to convey electrode sheets and includes a first conveying roller and a second conveying roller, both of which are rotatably mounted on the base. The lifting assembly includes a first locking block and a second locking block. One end of the electrode welding assembly passes through the first locking block, and the other end of the electrode welding assembly passes through the second locking block. The electrode welding assembly is located between the base and the lifting assembly.

[0007] The electrode welding device further includes a ceramic welding seat. The top of the base is provided with a placement end face. The ceramic welding seat is disposed on the placement end face. The ceramic welding seat is located between the first guide roller and the second guide roller. The ceramic welding seat is located below the welding action end of the electrode welding assembly. The ceramic welding seat is used to support the electrode so that the electrode welding assembly can weld the electrode.

[0008] In one embodiment, the ceramic welding base further includes a plurality of support portions, each of which is arranged in a straight line symmetrically with the other support portion.

[0009] In one embodiment, the base further includes a placement boss and a guide roller mounting plate. The ceramic welding seat is provided with the end face of the placement boss. The guide roller mounting plate is disposed on the side wall of the base. One side of the guide roller mounting plate is slidably connected to the first guide roller, and the other side of the guide roller mounting plate is slidably connected to the second guide roller, so that the ceramic welding seat is located between the first guide roller and the second guide roller.

[0010] In one embodiment, the first locking block is detachably connected to one end of the electrode welding assembly, and the second locking block is detachably connected to the other end of the electrode welding assembly.

[0011] In one embodiment, the lifting assembly includes a driver, a drive base, and a lifting connecting plate. The driver is disposed on the end face of the drive base, and the power output end of the driver is connected to one side of the lifting connecting plate. The other side of the lifting connecting plate is connected to the first locking block and the second locking block, respectively.

[0012] In one embodiment, the first locking block includes a first fixing block, a first stud, and a first adjusting block. The first fixing block is connected to the bottom of the lifting connecting plate. The first fixing block has a first screw hole, the first adjusting block has a second screw hole, and the first stud is screwed into the first screw hole and the second screw hole respectively.

[0013] In one embodiment, the second locking block includes a second fixing block, a second stud, and a second adjusting block. The second fixing block is connected to the bottom of the lifting connecting plate. The second fixing block has a third screw hole, and the second adjusting block has a fourth screw hole. The second stud is screwed into the third screw hole and the fourth screw hole, respectively.

[0014] In one embodiment, the lifting assembly further includes a guide rail slider, a limiting plate, and a fixed rail slide rod. The guide rail slider is disposed on the end face of the drive base and has a sliding cavity. One end of the guide rail slide rod passes through the sliding cavity and is connected to the lifting connecting plate, and the other end of the guide rail slide rod is connected to the limiting plate.

[0015] In one embodiment, the electrode welding assembly further includes a welding head and a transducer, one end of the welding head being detachably connected to the first locking block, and the energy output end of the transducer being connected to the other end of the welding head through the second locking block.

[0016] An electrode welding apparatus includes the electrode welding device described in any of the above embodiments.

[0017] Compared with the prior art, this disclosure has at least the following advantages:

[0018] One end of the electrode welding assembly is threaded through a first locking block, and the other end is threaded through a second locking block. Since the welding assembly is located between the base and the lifting assembly, the first and second guide rollers are rotatably mounted on the base, causing the electrode to move along the first guide roller to the second guide roller. The lifting assembly can control the lifting height of the electrode welding assembly to weld the electrode. A placement end face is provided on the top of the base, and a ceramic welding seat is placed on this end face. The ceramic welding seat is located below the welding end of the electrode welding assembly. When the electrode welding assembly moves downwards, it contacts the part of the electrode to be welded, causing the electrode to abut against the supporting surface of the ceramic welding seat, thus welding the surface of the electrode. By abutting the electrode against the supporting surface of the ceramic welding seat, the overheating of the welding seat and electrode due to the metal material is avoided when the electrode welding assembly acts on the metal welding seat for a long time, preventing over-welding of the electrode due to increased welding seat temperature.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0028] like Figure 1As shown, an embodiment of the electrode welding device 10 includes a base 100, a lifting assembly 200, an electrode welding assembly 300, a roller assembly 400, and a ceramic welding seat 500. The roller assembly 400 is used to transport the electrode 600 and includes a first roller 410 and a second roller 420, both of which are rotatably mounted on the base 100. The lifting assembly 200 includes a first locking block 210 and a second locking block 220. One end of the electrode welding assembly 300 passes through the first locking block 210, and the other end of the electrode welding assembly 300... The electrode welding assembly 300 is located between the base 100 and the lifting assembly 200, with the end inserted through the second locking block 220. The base 100 has a placement end face 110 on its top, and the ceramic welding seat 500 is disposed on the placement end face 110. The ceramic welding seat 500 is located between the first guide roller 410 and the second guide roller 420, and is located below the welding end of the electrode welding assembly 300. The ceramic welding seat 500 is used to support the electrode 600 so that the electrode welding assembly 300 can weld the electrode 600.

[0029] It is understood that one end of the electrode welding assembly 300 is threaded through the first locking block 210, and the other end is threaded through the second locking block 220. Since the welding assembly is located between the base 100 and the lifting assembly 200, the first guide roller 410 and the second guide roller 420 are rotatably mounted on the base 100, causing the electrode 600 to move along the first guide roller 410 to the second guide roller 420. Simultaneously, because the lifting assembly 200 can control the lifting height of the electrode welding assembly 300 to weld the electrode 600, and a placement end face 110 is provided on the top of the base 100, on which the ceramic welding seat 500 is placed. On surface 110, the ceramic welding seat 500 is located below the welding end of the electrode welding assembly 300. When the electrode welding assembly 300 moves downward, it will contact the part of the electrode 600 that needs to be welded, so that the electrode 600 abuts against the support surface of the ceramic welding seat 500, thereby welding the surface of the electrode 600. By abutting the electrode 600 against the support surface of the ceramic welding seat 500, the electrode welding assembly 300 is prevented from overheating locally due to the metal welding seat when it is in contact with the metal welding seat for a long time, thus avoiding over-welding of the electrode 600 due to the temperature rise of the welding seat.

[0030] like Figure 1As shown, in one embodiment, the ceramic welding base 500 further includes a plurality of support portions 510, each of which is linearly symmetrical to another. It can be understood that by providing a plurality of support portions 510 in the ceramic welding base 500, with each support portion 510 linearly symmetrical to another, the overall structural stability of the ceramic welding base 500 can be effectively improved, its load-bearing capacity enhanced, and the accuracy and reliability of the welding portion of the electrode 600 ensured. This prevents deformation or displacement problems caused by insufficient support from the ceramic welding base 500 during the welding process. Furthermore, having multiple support portions 510 allows for replacement of the support portion 510 during electrode 600 welding, avoiding damage to the overall structure of the ceramic welding base 500 due to long-term use of a single support portion 510.

[0031] Combination Figure 1 and Figure 2 As shown, the base 100 further includes a placement boss 120 and a guide roller mounting plate 130. The ceramic welding seat 500 is provided with the end face of the placement boss 120. The guide roller mounting plate 130 is disposed on the side wall of the base 100. One side of the guide roller mounting plate 130 is slidably connected to the first guide roller 410, and the other side of the guide roller mounting plate 130 is slidably connected to the second guide roller 420, so that the ceramic welding seat 500 is located between the first guide roller 410 and the second guide roller 420. It is understood that by setting a placement boss 120 on the base 100, the ceramic welding seat 500 is placed on the end face of the placement boss 120. At the same time, because the first guide roller 410 and the second guide roller 420 are set at both ends of the guide roller mounting plate 130, and the ceramic welding seat 500 is located between the first guide roller 410 and the second guide roller 420, when the electrode 600 passes through the first guide roller 410 and slides above the ceramic welding seat 500, the lifting component 200 presses down the electrode welding component 300 to weld the electrode 600, and then flows out through the second guide roller 420 to the next process; and the first guide roller 410 and the second guide roller 420 are slidably connected to both sides of the guide roller mounting plate 130, so that the first guide roller 410 and the second guide roller 420 can be finely adjusted according to the actual needs, ensuring that the electrode 600 can be conveyed from the first guide roller 410 to the second guide roller 420.

[0032] Combination Figure 1 and Figure 2As shown, in one embodiment, the first locking block 210 is detachably connected to one end of the electrode welding assembly 300, and the second locking block 220 is detachably connected to the other end of the electrode welding assembly 300. It can be understood that by designing the first locking block 210 and the second locking block 220 to be detachably connected to both ends of the electrode welding assembly 300, the first locking block 210 and the second locking block 220 can be disassembled according to different needs, allowing for the replacement of electrode welding assemblies 300 of different specifications to meet the processing requirements of the electrode 600.

[0033] Combination Figure 1 and Figure 2 As shown, the first locking block 210 further includes a first fixing block 2110, a first stud 2130 and a first adjusting block 2120. The first fixing block 2110 is connected to the bottom of the lifting connecting plate 250. The first fixing block 2110 has a first screw hole 2111, the first adjusting block 2120 has a second screw hole 2121, and the first stud 2130 is screwed into the first screw hole 2111 and the second screw hole 2121 respectively. It is understood that by providing a second screw hole 2121 in the first adjusting block 2120 and a first screw hole 2111 in the first fixing block 2110, and by screwing the first stud 2130 into the first screw hole 2111 and the second screw hole 2121 respectively, the first stud 2130 can be turned to adjust the tightness between the first adjusting block and the first fixing block 2110, thereby satisfying the end of the electrode welding assembly 300 of different specifications, thereby adjusting one end of the electrode welding assembly 300, and ensuring that the electrode welding assembly 300 maintains the correct position for welding the electrode 600 during the welding process.

[0034] like Figure 2 As shown, the second locking block 220 further includes a second fixing block 2210, a second stud 2230 and a second adjusting block 2220. The second fixing block 2210 is connected to the bottom of the lifting connecting plate 250. The second fixing block 2210 has a third screw hole 2211, and the second adjusting block 2220 has a fourth screw hole 2221. The second stud 2230 is screwed into the third screw hole 2211 and the fourth screw hole 2221 respectively. It is understood that the second fixing block 2210 has a third screw hole 2211, and the second adjusting block 2220 has a fourth screw hole. By screwing the second stud 2230 into the third screw hole 2211 and the fourth screw hole 2221, the relative position between the second fixing block 2210 and the second adjusting block 2220 can be adjusted, thereby achieving precise adjustment of the other end of the electrode welding assembly 300. This allows users to quickly and accurately adjust the position and tightness of the electrode welding assembly 300 according to different electrode 600 specifications and welding requirements.

[0035] Combination Figure 2 and Figure 3 As shown, in one embodiment, the lifting assembly 200 includes a driver 230, a drive base 240, and a lifting connecting plate 250. The driver 230 is disposed on the end face of the drive base 240, and the power output end of the driver 230 is connected to one side of the lifting connecting plate 250. The other side of the lifting connection is connected to the first locking block 210 and the second locking block 220, respectively. It is understood that the driver 230 is set on the end face of the drive base 240. The driver 230 is cylinder driven. Since the power output end of the driver 230 is connected to one side of the lifting connecting plate 250, and the other side of the lifting connecting plate 250 is connected to the first locking block 210 and the second locking block 220 respectively, and since the two ends of the electrode welding assembly 300 are connected to the first locking block 210 and the second locking block 220 respectively, when the power output end of the driver 230 pushes the lifting connecting plate 250 to move up and down, it drives the electrode welding assembly 300 to move down, thereby performing welding work on the electrode 600.

[0036] Combination Figure 2 and Figure 3 As shown, the lifting assembly 200 further includes a guide rail slider 260, a limiting plate 270, and a fixed rail slide rod 280. The guide rail slider 260 is disposed on the end face of the drive base 240. The guide rail slider 260 has a sliding cavity 2610. One end of the fixed rail slide rod 280 passes through the sliding cavity 2610 and is connected to the lifting connecting plate 250. The other end of the fixed rail slide rod 280 is connected to the limiting plate 270. It is understood that by setting a guide rail slider 260 on the end face of the lifting assembly 200, and the guide rail slider 260 having a sliding cavity 2610, one end of the fixed rail slide rod 280 passes through the sliding cavity 2610 and is connected to the lifting plate, and the other end of the fixed rail slide rod 280 is connected to the limiting plate 270; because the fixed rail slide rod 280 always slides based on the sliding cavity 2610 of the guide rail slider 260, it ensures that the overall up and down movement trajectory of the lifting assembly 200 is maintained in the horizontal direction of the sliding cavity 2610, and the fixed rail slide rod 280 is connected to the limiting plate 270. When the fixed rail slide rod 280 moves downward to the maximum stroke in the sliding cavity 2610, the limiting plate 270 will abut against the end face of the guide rail slider 260, thereby restricting the lifting assembly 200 from continuing to move downward.

[0037] Combination Figure 2 and Figure 3As shown, in one embodiment, the electrode welding assembly 300 further includes a welding head 310 and a transducer 320. One end of the welding head 310 is detachably connected to the first locking block 210, and the energy output end of the transducer 320 is connected to the other end of the welding head 310 via the second locking block 220. It can be understood that by detachably connecting one end of the welding head 310 to the first locking block 210, the first locking block 210 can be adjusted to change the welding position of the welding head 310. Simultaneously, because the energy output end of the transducer 320 is connected to the other end of the welding head 310 via the second locking block 220, the transducer 320 can transmit ultrasonic energy to the welding head 310, allowing the welding head 310 to weld the electrode 600 using the transmitted energy.

[0038] Combination Figure 1 As shown, the present invention also provides an electrode welding device, including the electrode welding apparatus 10 described in any of the above embodiments. It can be understood that the ceramic welding seat 500 is disposed below the electrode 600. When the electrode welding assembly 300 moves downward, it contacts the part of the electrode 600 that needs to be welded, causing the electrode 600 to abut against the supporting surface of the ceramic welding seat 500, thereby welding the surface of the electrode 600. By abutting the electrode 600 against the supporting surface of the ceramic welding seat 500, the electrode welding assembly 300 avoids localized overheating of the welding seat and electrode 600 due to the metal material of the welding seat when it operates on the metal welding seat for a long time, thus preventing over-welding of the electrode 600 due to increased welding seat temperature.

[0039] Compared with the prior art, this disclosure has at least the following advantages:

[0040] One end of the electrode welding assembly 300 is threaded through the first locking block 210, and the other end is threaded through the second locking block 220. Since the welding assembly is located between the base 100 and the lifting assembly 200, the first guide roller 410 and the second guide roller 420 are rotatably mounted on the base 100, causing the electrode 600 to move along the first guide roller 410 to the second guide roller 420. Simultaneously, the lifting assembly 200 can weld the electrode 600 by controlling the lifting height of the electrode welding assembly 300. A placement end face 110 is provided on the top of the base 100, and the ceramic welding seat 500 is placed on the placement end face 110. On the 0, the ceramic welding seat 500 is located below the welding end of the electrode welding assembly 300. When the electrode welding assembly 300 moves downward, it will contact the part of the electrode 600 that needs to be welded, so that the electrode 600 abuts against the support surface of the ceramic welding seat 500, thereby welding the surface of the electrode 600. By abutting the electrode 600 against the support surface of the ceramic welding seat 500, the electrode welding assembly 300 is prevented from overheating locally on the welding seat and the electrode 600 due to the metal welding seat when it is in contact with the metal welding seat for a long time. This also avoids the electrode 600 from being over-welded due to the temperature rise of the welding seat.

[0041] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
