Description

Technical Field

[0001] This application relates to the field of cylindrical battery production, and more particularly to a cylindrical battery liquid injection nozzle adjustment device and formation equipment. Background Technology

[0002] During the formation process before cylindrical batteries leave the factory, gases generated by the chemical reaction need to be expelled by applying negative pressure to prevent the batteries from bulging. In this process, the tight fit between the battery's injection nozzle and the formation suction nozzle is crucial to avoid air leakage. However, the eccentric design of the cylindrical battery's injection nozzle makes it difficult to position the batteries in the tray. The nozzles are oriented differently, resulting in a dispersed state within the tray, with each battery's nozzle not aligned in the same direction or a straight line, thus affecting formation efficiency.

[0003] Currently, the adjustment of the injection nozzle direction mainly relies on manual labor or automated equipment. Large-scale production lines use CCD (Charge-Coupled Device) imaging combined with robotic arms to precisely adjust the nozzle through algorithms, but this solution is costly and the equipment maintenance is complex. In small-scale production lines, manual adjustment has become the mainstream, but visual inspection or ruler marking methods are not only slow, but also difficult to guarantee positional accuracy, failing to meet the high concentricity requirements of the suction nozzle and injection nozzle during formation. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0037] Cylindrical batteries require a formation process during manufacturing, primarily involving applying negative pressure to expel gases from the chemical reaction and prevent battery bulging. This requires a tight fit between the negative pressure and the filling nozzles to maintain airtightness and prevent leakage. Existing methods typically use CCD imaging combined with a robotic arm to ensure consistent nozzle orientation across all cylindrical batteries. However, this approach is costly for small-scale production lines. Small-scale production lines primarily rely on manual visual inspection to adjust the nozzle positions, but this method is inefficient. Therefore, this application proposes a follower 400 positioned above the cylindrical battery. An elastic positioning member 500, adapted to the number of batteries, is mounted on the end face of the follower 400 facing the cylindrical battery. Initially, the elastic positioning member 500 contacts the upper surface of the battery. Then, simply rotating the battery allows the elastic positioning member 500 to partially extend into the filling nozzle, thus confirming the nozzle position. This significantly improves the efficiency of maintaining consistent nozzle orientation across all cylindrical batteries; simply rotating each battery ensures that the filling nozzles are aligned in a uniform straight line or direction.

[0038] This application provides a cylindrical battery filler nozzle adjustment device, which includes a base 100, a sliding frame 200, a column 300, a follower 400, and an elastic positioning member 500.

[0039] See Figure 1 As shown, the base 100 is used to support the cylindrical battery, the sliding frame 200 is slidably disposed on the base 100, the sliding frame 200 can move along a second preset direction, the column 300 is slidably disposed on the sliding frame 200, the column 300 can move along the second preset direction, the driven member 400 is fixedly connected to the end of the column 300 away from the sliding frame 200, and a plurality of elastic positioning members 500 are mounted on the driven member 400.

[0040] In some embodiments, the first preset direction described above is a horizontal or vertical direction, so as to... Figure 1For example, the first preset direction is the longitudinal direction of the base 100, the second preset direction mentioned above is the height direction, and the cylindrical batteries are distributed in a rectangular array. The number of elastic positioning members 500 is the same as the number of cylindrical batteries distributed laterally.

[0041] Specifically, when the position of the battery injection nozzle needs to be adjusted, it is only necessary to change the position of the column 300 and the driven member 400 by sliding the sliding frame 200, so that the elastic positioning member 500 is located in the preset position. Under the action of gravity, the driven member 400 and the column 300 will move downward so that the elastic positioning member 500 contacts the upper surface of the cylindrical battery below it. If the elastic positioning member 500 does not penetrate into the injection nozzle below it, it is only necessary to rotate the battery so that the injection nozzle coincides with the elastic positioning member 500. Since all the elastic positioning members 500 are located on the same straight line, if the injection nozzle of each battery coincides with the elastic positioning member 500 above it, the position of the injection nozzle of each battery is also on the same straight line, so that the position of the injection nozzle of each battery is consistent, which facilitates the negative pressure extraction in the subsequent formation process.

[0042] In some embodiments, to prevent the elastic positioning member 500 from contacting the battery surface and causing damage, the elastic positioning member 500 is made of a non-metallic material. Specifically, the elastic positioning member 500 is a rubber nail that can deform to a certain extent in the height direction. Specifically, when the rubber nail contacts the battery surface, it will expand or contract to a certain extent under the gravity of the driven member 400. When the battery rotates, if the position of the injection nozzle coincides with that of the rubber nail, the rubber nail will partially penetrate into the injection nozzle under its own elasticity, thereby determining the position of the injection nozzle. The rubber nail can be made of materials such as rubber that can deform to a certain extent under stress and will return to its initial state after the stress condition is removed. Furthermore, since the rubber nail is a non-metallic material, it will not damage the battery surface during battery rotation.

[0043] For example, the elastic positioning element 500 can also be replaced by a spring plunger. The spring plunger is mainly composed of a spring, a ball head, and other structures. That is, the ball head can compress the spring to contract. In order to prevent damage to the battery surface, the ball head can be made of non-metallic material. The ball head compresses the spring to contract in the initial state. When it coincides with the injection nozzle, the ball head will partially penetrate into the injection nozzle to achieve positioning.

[0044] A sliding structure 110 is provided between the sliding frame 200 and the base 100. The sliding structure 110 includes a guide rail 111 fixedly disposed on the surface of the base 100, and a slider 112 slidably disposed on the guide rail 111. The sliding frame 200 is fixedly mounted on the slider 112.

[0045] Please see Figure 2As shown, in order to ensure that the sliding frame 200 can move radially, a slider 112 is fixedly installed at the bottom of the sliding frame 200, so that the slider 112 cooperates with the guide rail 111 on the base 100 to achieve sliding.

[0046] The sliding frame 200 includes a driven plate 210, on which at least one guide rod 220 is fixedly installed. A fixing block 230 is fixedly installed at the end of the guide rod 220 away from the driven plate 210. A guide hole 240 is provided through the fixing block 230, and the column 300 passes through the guide hole 240.

[0047] Please continue reading. Figure 2 As shown, in this embodiment, in order to make the movement of the follower 400 more stable, there are two sliding structures 110, two sliding frames 200 and two columns 300. The two ends of the follower 400 are respectively connected to the columns 300, so that the two columns 300 and one follower 400 form a stable frame.

[0048] Furthermore, when adjusting the position of the battery filling nozzle, in order to ensure that the elastic positioning member 500 is always in contact with the battery surface, the column 300 is inserted through the guide hole 240, thereby realizing the sliding connection between the column 300 and the fixed block 230. Under the action of gravity, the two columns 300 and the driven member 400 have a downward tendency, so that the elastic positioning member 500 is always in contact with the upper surface of the cylindrical battery.

[0049] A limiting plate 260 is provided at the end of the column 300 away from the driven member 400, and the limiting plate 260 is slidably connected to the guide rod 220.

[0050] An elastic element 250 is sleeved on the guide rod 220, and the elastic element 250 is located between the fixing block 230 and the limiting plate 260.

[0051] Continue reading Figure 2 As shown, during the rotation of the cylindrical battery, in order to ensure that the elastic positioning member 500 remains in contact with the battery surface, a limiting plate 260 is fixedly installed at the end of the column 300 away from the driven member 400. The limiting plate 260 has a hole (not shown in the figure) that matches the guide rod 220. The limiting plate 260 and the guide rod 220 are slidably connected in the vertical direction through the hole. The elastic member 250 is sleeved on the guide rod 220 and is located between the fixed block 230 and the limiting plate 260. The elastic force of the elastic member 250 continuously provides a downward force to the limiting plate 260, thereby causing the column 300 and the driven member 400 to have a downward tendency, so that the elastic positioning member 500 always contacts the upper surface of the cylindrical battery.

[0052] For example, the elastic element 250 is a compression spring.

[0053] The column 300 includes a smooth rod portion 310, one end of which is provided with a first threaded section 320, and the end of the smooth rod portion 310 away from the first threaded section 320 is provided with a second threaded section 330. The first threaded section 320 is connected to the driven member 400, and the second threaded section 330 is connected to the limiting plate 260.

[0054] Please see Figure 2 and Figure 3 To facilitate the assembly of the entire device, the column 300 is divided into a smooth rod portion 310, a first threaded section 320, and a second threaded section 330. The first threaded section 320 is located at both ends of the smooth rod portion 310. Specifically, the outer surfaces of the first threaded section 320 and the second threaded section 330 are provided with external threads. Furthermore, to facilitate installation, threaded holes are provided at the end of the driven member 400 and on the limiting plate 260, so as to facilitate threaded connection and installation with the first threaded section 320 and the second threaded section 330.

[0055] The driven member 400 is provided with a plurality of connecting structures 410. The elastic positioning member 500 is connected to the driven member 400 through the connecting structures 410. The connecting structure 410 includes a mounting hole 411 opened on the driven member 400. A mounting block 412 is installed in the mounting hole 411. A receiving hole 413 is opened at the end of the mounting block 412 away from the driven member 400. The elastic positioning member 500 is partially installed in the receiving hole 413.

[0056] Please see Figure 4 and Figure 5 The elastic positioning element 500 has multiple components, and the driven element 400 is a crossbar with a rectangular cross section. In order to install each elastic positioning element 500, the number of driven elements 400 is the same as the number of elastic positioning elements 500. Specifically, the driven element 400 has multiple mounting holes 411 on its surface facing the base 100. The mounting holes 411 can be through holes or blind holes. Specifically, the inner wall of the mounting hole 411 has an internal thread. A mounting block 412 is threaded into the mounting hole 411, and the end of the mounting block 412 facing away from the driven element 400 has a receiving hole 413. Part of the elastic positioning element 500 is installed in the receiving hole 413. Part of the elastic positioning element 500 can be installed inside the receiving hole 413 by interference fit, so that part of the elastic positioning element 500 is exposed to the outside and can contact the upper surface of the cylindrical battery.

[0057] The base 100 is provided with a carrier 120 for supporting cylindrical batteries. The carrier 120 includes a carrier plate 121 fixedly mounted on the base 100. Multiple connecting rods 122 are fixedly mounted on the carrier plate 121. Fixing plates 123 are installed at the ends of the multiple connecting rods 122 away from the carrier plate 121. Multiple placement holes 124 are provided on the fixing plate 123, and the placement holes 124 are distributed in a rectangular array on the fixing plate 123.

[0058] Please see Figure 1 and Figure 6 As shown, in order to evenly distribute the cylindrical batteries, a carrier plate 121 is installed on the upper surface of the base 100. Specifically, the carrier plate 121 can be welded and fixed to the base 100, or it can be installed on the upper surface of the base 100 using a detachable structure. For example, multiple threaded holes can be opened on the upper surface of the base 100, and multiple through holes can also be opened on the carrier plate 121, so that the threaded holes on the base 100 correspond one-to-one with the through holes on the carrier plate 121. Then, bolts are used to thread the carrier plate 121 through the through holes and the threaded holes on the base 100 to complete the installation of the carrier plate 121.

[0059] Furthermore, a fixing plate 123 is provided above the carrier plate 121. The carrier plate 121 and the fixing plate 123 are connected by multiple carrier plates 121. The fixing plate 123 has multiple placement holes 124 arranged in a rectangular array. The shape of the placement holes 124 is the same as the diameter of the cylindrical battery. In order to allow the cylindrical battery to enter the placement hole 124 smoothly, in practice, the diameter of the placement hole 124 should be slightly larger than the diameter of the cylindrical battery. After the cylindrical battery is placed into the placement hole 124, the bottom of the battery abuts against the carrier plate 121, and the carrier plate 121 supports the battery.

[0060] For example, the carrier plate 121 and the fixing plate 123 are both rectangular and the same size, and there are four connecting rods 122, which are distributed at the four corners of the carrier plate 121 and the fixing plate 123.
