DETAILED DESCRIPTION

[0038] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please see the attached Figure 1 The busbar welding positioning device of the present invention includes a base 1, a primary positioning module 2, a secondary positioning module 5, and a moving module 3. The base 1 is divided into a pre-positioning area 11 and a welding area 12; the primary positioning module 2 is arranged in the pre-positioning area 11, and the primary positioning module 2 is used for the initial positioning of the busbar 4; the secondary positioning module 5 is arranged in the welding area 12, and the secondary positioning module 5 is used for the secondary positioning of the busbar 4; the moving module 3 moves between the pre-positioning area 11 and the welding area 12, and the moving module 3 includes a moving component 31 and an adsorption component 32, and the adsorption component 32 is connected to the moving component 31; the adsorption component 32 is used to adsorb the busbar 4, so that the moving component 31 drives the adsorption component 32 to move the busbar 4 from the primary positioning module 2 in the pre-positioning area 11 to the secondary positioning module 5 in the welding area 12.

[0042] The pre-positioning area 11 is used for preliminary positioning of the busbar 4 , and the welding area 12 is used for welding the busbar 4 and the battery cell 6 .

[0043] The operation principle of the busbar 4 welding positioning device in this embodiment is as follows: the busbar 4 is placed on the primary positioning module 2 for preliminary positioning, and then the adsorption component 32 is moved to the top of the primary positioning module 2 by the moving component 31, and the busbar 4 located on the primary positioning module 2 is adsorbed and positioned by the adsorption component 32. When the adsorption component 32 completely adsorbs the busbar 4, the moving component 31 drives the adsorption component 32 to move to the secondary positioning module 5 of the welding area 12, and places the busbar 4 on the secondary positioning module 5 at the upper end of the battery cell 6, thereby achieving secondary positioning between the busbar and the battery cell 6, ensuring the accuracy of the placement of the busbar position, so that the corresponding assembly welding operation can be directly performed. In this way, in the overall operation process, the uniformity of the placement position of the busbar 4 can be guaranteed, avoiding the phenomenon of adjusting the position of the busbar 4 during the assembly process, effectively reducing the adjustment deviation of the busbar 4, and effectively simplifying the positioning operation during the assembly process of the busbar 4, thereby strengthening the rhythm of the assembly process, achieving continuous assembly operation, and improving assembly efficiency.

[0044] In addition, by positioning the busbar 4 twice, the positioning accuracy of the busbar 4 is improved accordingly, thereby ensuring the quality of assembly of the busbar 4 and the battery cell 6, and effectively reducing the problem of low assembly yield of cylindrical batteries caused by positioning deviation.

[0045] In this structure, the positioning function and the movement function operate independently, which is highly practical and effectively ensures the stable positioning and efficient movement of the busbar 4. The overall operation stroke is streamlined and not lengthy, making the structure compact in space.

[0046] In addition, please see the attached Figure 1 The primary positioning module 2 includes several positioning components 21 and several adsorption components 32, which can be arranged corresponding to the positioning components 21. Preferably, there are four positioning components 21 and four adsorption components 32. This method can simultaneously perform initial positioning and movement on multiple busbars 4, enabling batch assembly of busbars 4 and effectively improving the production efficiency of cylindrical batteries.

[0047] In some embodiments, see the attached Figure 2 The one-time positioning module 2 includes a first positioning portion 211. The first positioning portion 211 is provided with a positioning groove 212 adapted to the convergence plate 4 and a plurality of air holes 213. The air holes 213 are distributed in the positioning groove 212. The air holes 213 are used to adsorb the convergence plate 4 located in the positioning groove 212. The compressed air is used in conjunction with the air holes 213 so that the air holes 213 have an adsorption force. In this way, the positioning principle of the convergence plate 4 by the one-time positioning module 2 is as follows: the convergence plate 4 is placed in the positioning groove 212. First, the edge of the convergence plate 4 is restricted by the positioning groove 212. Secondly, the side of the convergence plate 4 in contact with the air holes 213 is adsorbed and positioned by suction, so that there is a double-layer positioning in the pre-positioning, which effectively ensures the stability of the initial positioning of the convergence plate 4.

[0048] In some embodiments, see the attached Figure 3 -Attached Figure 4 The primary positioning module 2 further includes a chuck component 214, which is disposed toward the positioning groove 212 to position the busbar 4. Through this arrangement, the primary positioning module 2 can further position the busbar 4, effectively enhancing the positioning stability of the busbar 4.

[0049] Specifically, the chuck assembly 214 includes a first cylinder 2141 and an opposing clamp 2142. The first cylinder 2141 is driven and connected to the clamp 2142 to clamp or move away from the busbar 4. The operating principle is that after the busbar 4 is placed in the positioning slot 212, the first cylinder 2141 is activated, driving the clamp 2142 toward the busbar, causing the clamp 2142 to press against the busbar 4, thereby repositioning the busbar 4, preventing it from deflecting, and further improving the positioning stability of the busbar 4.

[0050] In some embodiments, a notch 215 is provided on the edge of the positioning groove 212, and the notch 215 is provided toward the positioning groove 212. The notch 215 corresponds to the clip 2142. When the clamping disc component 214 needs to press the busbar 4, the clip 2142 is inserted into the notch 215, thereby fixing the busbar 4. This arrangement facilitates the first positioning portion 211 of different structures to smoothly insert the clip 2142 into the notch 215, has a wide range of applications, and can ensure the stability of the busbar. In some embodiments, please refer to the attached Figure 5 -Attached Figure 6 The secondary positioning module 5 includes a second positioning portion 51, which is provided with a positioning hole 52 adapted for the busbar 4 and a plurality of air pipes 53. The air pipes 53 are annularly arranged through the second positioning portion 51 and communicate with the positioning holes 52. The air pipes 53 are used to adsorb the edge of the busbar 4. Through the setting of the secondary positioning module 5, the adsorption component 32 moves the busbar 4 to the top of the secondary positioning module 5 and places the busbar 4 into the positioning holes 52, so that the busbar 4 and the battery cells 6 are precisely placed. The air pipes 53 also generate negative pressure at the edge of the busbar 4, thereby further positioning the busbar 4 and ensuring the stable and accurate placement of the busbar.

[0051] In some embodiments, see the attached Figure 7 The adsorption component 32 includes a suction cup 321 and a baffle 322. The baffle 322 is arranged in a ring along the edge of the suction cup 321. An air channel 3211 is provided in the suction cup 321. The air channel 3211 adsorbs the busbar 4 through the baffle 322. The air channel 3211 circulates compressed air to generate suction to adsorb the busbar 4. In this way, the adsorption component 32 sucks the busbar 4 from the positioning component 21 to the welding area 12 through the suction cup 321. The suction cup 321 can ensure that the position of the busbar 4 is fixed and does not shift, effectively ensuring the subsequent assembly quality of the busbar 4 with the battery cell 6. In addition, by providing the baffle 322, during the welding process of the busbar 4 and the battery cell 6, the busbar 4 that is not blocked by the baffle 322 can be welded, avoiding the phenomenon of welding position deviation, and effectively ensuring the accuracy of the welding point of the busbar 4.

[0052] In some embodiments, see the attached Figure 8 -Attached Figure 9 The moving assembly 31 includes a motor 311, a moving plate 312, and a second slide rail 313. The motor 311 is drivably connected to the moving plate 312. The moving plate 312 is provided with a second slider 3121 movably connected to the second slide rail 313. The second slide rail 313 is provided on both sides of the primary positioning module 2. The moving plate 312 is connected to the adsorption assembly 32. The movement of the moving plate 312 by the motor 311 is achieved by the existing screw rod.

[0053] Through the setting of the above-mentioned moving component 31, the moving component 31 drives the adsorption component 32 to move in the pre-positioning area 11 and the welding area 12, and the process of its moving action is: starting the motor 311, driving the moving plate 312 to move along the second slide rail 313 toward the pre-positioning area 11, until the adsorption component 32 and the positioning component 21 are relatively arranged, the adsorption component 32 adsorbs the busbar 4, and the positioning component 21 then makes the clamping disc component 214 release the busbar 4, that is, the clamp 2142 is pulled out of the slot 215, and the air hole 213 does not generate adsorption force, so that the adsorption component 32 adsorbs the busbar 4, and then reverses through the motor 311, and the second slider 3121 and the second slide rail 313 cooperate to move the adsorption component 32 to the welding area 12, so that the busbar 4 moves to the upper end of the battery cell 6, which is convenient for the subsequent assembly of the battery cell 6 and the busbar 4. The moving assembly 31 has a simple structure, which facilitates installation and subsequent maintenance of the moving assembly 31 , and the second slide rails 313 and the second sliders 3121 on both sides cooperate to improve the stability of the movement of the moving assembly 31 .

[0054] Example 2:

[0055] The difference between this embodiment and embodiment 1 is that, see Figures 10 and 11 The mobile module 3 of this embodiment also includes a lifting assembly 33, which is connected to the adsorption assembly 32; the lifting assembly 33 includes a fixed part 331, a first slide rail 332 and a second cylinder 333, the first slide rail 332 is arranged on both sides of the fixed part 331, one end of the second cylinder 333 is connected to the fixed part 331, and the other end of the second cylinder 333 is connected to the adsorption assembly 32; the adsorption assembly 32 includes a first slider 323 adapted to the first slide rail 332, and the first slider 323 is movably connected to the first slide rail 332.

[0056] The arrangement of the lifting assembly 33 facilitates the upward and downward movement of the adsorption assembly 32, thereby changing the distance between the adsorption assembly 32 and the positioning assembly 21. This allows the adsorption assembly 32 to move closer to or further away from the positioning assembly 21. When approaching the positioning assembly 21, the adsorption assembly 32 can be brought into close proximity with the conduit tray 4 in the positioning assembly 21. This shortens the distance between the adsorption assembly 32 and the conduit tray 4, thereby improving the adsorption capacity of the adsorption assembly 32 on the conduit tray 4 and ensuring stable positioning of the conduit tray 4 by the adsorption assembly 32. When the adsorption assembly 32 is away from the positioning assembly 21, a certain distance exists between the two, ensuring smooth movement of the adsorption assembly 32 driven by the moving assembly 31 and avoiding obstructed movement.

[0057] Specifically, the lifting assembly 33 operates by activating the second cylinder 333 to move the adsorption assembly 32 toward or away from the positioning assembly 21. The first slide rail 332 and the first slider 323 cooperate to improve the movement stability of the adsorption assembly 32. The overall operation is simple, consumes little energy, and is easy to install and maintain.

[0058] In some embodiments, a spring 334 is provided between the lifting assembly 33 and the adsorption assembly 32. This arrangement allows the spring 334 to cushion any excessive upward or downward movement of the lifting assembly 33 when the lifting assembly 33 drives the adsorption assembly 32 to move upward or downward, thereby enhancing the protection of the adsorption assembly 32 and the second cylinder 333.

[0059] Example 3:

[0060] The difference between this embodiment and embodiment 2 is that, see Figure 12 The mobile module 3 of this embodiment further includes an adjustment assembly 34, which is connected to the adsorption assembly 32. The adjustment assembly 34 includes a slide cylinder 341, a connecting plate 342, and an adjustment rod 343. The slide cylinder 341 is connected to the connecting plate 342, which is adjustably connected to the adjustment rod 343. The adjustment rod 343 is connected to the adsorption assembly 32. The fixed connection between the adjustment rod 343, the connecting plate 342, and the adsorption assembly 32 can be tightened by screws.

[0061] Through this setting, the distance between the adsorption component 32 and the battery cell 6 during the welding process can be achieved in two ways. One way is to start the slide cylinder 341, drive the connecting plate 342 and the adjusting rod 343 to move up and down, thereby driving the adsorption component 32 to move up and down, and then achieve the adsorption component 32 close to or away from the battery cell 6. Another way is to control the connection position of the adjusting rod 343 on the connecting plate 342 to achieve the distance between the adsorption component 32 and the battery cell 6. The two methods are used in combination to adapt to the diversity of the distance between the adsorption component 32 and the battery cell 6, thereby ensuring the consistency of the welding height of the busbar 4 and the battery cell 6, and ensuring the production performance of the battery.
