Description

Technical Field

[0001] The present application belongs to the technical field of battery production, and specifically relates to a nail pulling device. Background Art

[0002] As the market for new energy vehicles gradually expands, lithium batteries still have a dominant advantage in the market share of power batteries, and the market demand for lithium battery production equipment has also increased. Square batteries need to go through a formation process during the production process. During the formation process, the injection port of the square battery needs to be temporarily sealed with a formation nail, and the sealed formation nail is removed after the formation is completed, so as to carry out the subsequent filling port sealing process. When pulling out the formation nails from the battery, it is necessary to detect whether there are any missing or broken formation nails in the entire row. The traditional detection method is to move the pulled formation nails into the slots and use whether the photoelectric transmission is blocked to determine whether there are any formation nails. When the entire row is detected, this detection method requires multiple pairs of photoelectric transmissions for detection, and the failure rate is high; on the other hand, the formation nails rub against the slots, and there is a risk of falling, which makes it impossible to detect accurate results from the slots; in addition, the electrolyte carried by the formation nails will scratch the slots, making it impossible for the formation nails to be completely placed in the slots, thereby affecting the detection, resulting in high detection errors.

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

In the description of this application, "vertical" means completely vertical at 90° or almost completely vertical, for example, an angle within the range of 80° to 100° is considered vertical. Similarly, "parallel" means completely parallel or almost completely parallel, for example, an angle within 10° of completely parallel is considered parallel.

[0037] The applicant noted that when testing the battery for pulling out the formation nails, it is necessary to detect whether there are any missed or broken formation nails in the entire row. The transmission detection method is to move the pulled out formation nails into the slots, and then use multiple sets of photoelectric switches in the entire row to detect whether the opposing photoelectrics are blocked to determine whether the formation nails are pulled out smoothly. However, for multiple pairs of opposing photoelectrics in the entire row of detection, photoelectric switch failures are prone to occur, misjudgments are prone to occur, and troubleshooting is difficult. At the same time, placing the pulled out formation nails on the slots is prone to the risk of falling, and the electrolyte will scratch the slots and cause detection errors.

[0038] In view of this, an embodiment of the present application provides a nail pulling device, aiming to solve at least one of the above problems.

[0039] like Figure 1-Figure 5 As shown, a nail pulling device of an embodiment of the present application includes a frame 1, a nail pulling assembly 2 and a detection assembly 3; the nail pulling assembly 2 is arranged on the frame 1, and the nail pulling assembly 2 includes a nail pulling claw 21, and the nail pulling claw 21 has a nail clamping space 211, and the nail clamping space 211 is used to accommodate the formation nails on the battery; so that the nail pulling claw 21 clamps and removes the formation nails; the detection assembly 3 includes a detection mechanism 31 and a moving mechanism 32, the moving mechanism 32 is arranged on the frame 1, and the detection mechanism 31 is movably arranged on the moving mechanism 32; the moving mechanism 32 is used to drive the detection mechanism 31 to move, so that the detection mechanism 31 is opposite to the nail clamping space 211.

[0040] In the embodiment of the present application, a set of detection mechanisms 31 is arranged to move on the motion mechanism 32 so that the detection mechanism 31 is directly opposite to the nail clamping space 211 of the nail pulling clamp 21, thereby detecting whether there is a chemically formed nail in the nail clamping space 211 to determine whether the nail pulling clamp 21 pulls out the chemically formed nail. The overall structure of the present application is simple, and the detection cost is effectively reduced. At the same time, the nail clamping space 211 is directly detected, which can avoid the problem of the chemically formed nail falling during the slot detection and the interference problem of the electrolyte, thereby improving the detection accuracy.

[0041] It should be noted that the nail pulling assembly 2 of the present application is opposite to the detection assembly 3, and the motion mechanism 32 of the detection assembly 3 is in the same extension direction as the nail pulling assembly 2. The detection mechanism 31 is opposite to the nail pulling assembly 2, and the detection mechanism 31 moves along the motion structure to cruise, so that the detection mechanism 31 is opposite to the nail clamping space 211 of the nail pulling clamp 21 on the nail pulling assembly 2, thereby obtaining the formed nail information in the nail clamping space 211. The formed nail information may specifically include whether there is a formed nail, no formed nail, or a formed nail is broken.

[0042] like Figure 1As shown, in some embodiments, the nail pulling assembly 2 includes a plurality of nail pulling clamps 21 spaced apart along the extending direction of the motion mechanism 32, and the motion mechanism 32 drives the detection mechanism 31 to move so that the detection mechanism 31 is opposite to the nail clamping space 211 of at least one nail pulling clamp 21. The movable detection mechanism 31 is used to detect the nail clamping spaces 211 of the plurality of nail pulling clamps 21 one by one.

[0043] like Figure 1-Figure 2 As shown, in some embodiments, the detection mechanism 31 includes a fixed structure 311 and a detection structure 313, the fixed structure 311 is movably disposed on the moving mechanism 32, and the detection structure 313 is adjustably connected to the fixed structure 311 along a direction in which the fixed structure 311 moves away from the moving mechanism 32, wherein the detection structure 313 is opposite to the nail clamping space 211 to obtain the formed nail information in the nail clamping space 211.

[0044] In the embodiment of the present application, the detection structure 313 is relative to the nail clamping space 211 of the nail pulling clamp 21 to obtain information on whether the chemical nail is pulled out. The fixed structure 311 is connected to the detection structure 313 and is movably arranged on the motion mechanism 32, which is used to drive the detection structure 313 to move along the motion mechanism 32, so that the detection structure 313 is relative to the nail clamping space 211 of the nail pulling clamp 21. At the same time, the detection structure 313 is adjustably connected to the fixed structure 311, which is convenient for adjusting the position of the detection structure 313 fixed to the fixed structure 311 according to the position of the nail clamping space 211, so that the detection structure 313 is set relative to the nail clamping space 211.

[0045] like Figure 1 As shown, in some embodiments, the nail pulling assembly 2 includes a plurality of nail pulling claws 21 spaced apart along the extension direction of the motion mechanism 32 , and the motion mechanism 32 drives the detection structure 313 to move so that the detection structure 313 is opposite to the nail clamping space 211 of at least one nail pulling claw 21 .

[0046] In the embodiment of the present application, by setting the detection structure 313 to move along the motion mechanism 32, the detection structure 313 is gradually realized to be opposite to the clamping space 211 of each nail pulling clamp 21 one by one along the motion direction, so as to obtain the information of the chemically formed nails in each clamping space 211, thereby realizing the detection and judgment of the extraction situation of the chemically formed nails at all the chemically formed nail points. At this time, the single detection structure 313 can not only accurately detect the chemically formed nail information in each clamping space 211, but also avoid the risk of the chemically formed nails falling due to the detection of multiple chemically formed nails placed on the notch, and also avoid the interference of the electrolyte on the detection result. At the same time, if the detection structure 313 fails, it can be discovered in time to facilitate timely troubleshooting.

[0047] Specifically, since the battery usually has a plurality of formation nails arranged in a row and spaced apart to be removed, in order to ensure the efficiency of nail removal, a plurality of nail removal claws 21 are usually provided to remove the formation nails. Therefore, the extension direction of the motion mechanism 32 of the embodiment of the present application is the same as the arrangement direction of the plurality of nail removal claws 21. The fixed structure 311 slides along the motion mechanism 32 with the detection structure 313 to detect the clamping spaces 211 of the plurality of nail removal claws 21 one by one.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments, a supporting structure 312 is provided on the side of the fixed structure 311 away from the moving mechanism 32, and the detecting structure 313 is connected to the end of the supporting structure 312 away from the fixed structure 311; the supporting structure 312 is provided with an adjusting hole 3121, and the adjusting hole 3121 extends along the fixed structure 311 toward the supporting structure 312, and the detecting structure 313 is adjustably connected to the fixed structure 311 through the adjusting hole 3121.

[0049] In the embodiment of the present application, the support structure 312 is used to support the detection structure 313 from the slide rail and extend it toward the nail pulling clamp 21. At the same time, the embodiment of the present application sets an adjustment hole 3121 in the extension direction of the support structure 312, so that the fixed position of the detection structure 313 in the extension direction of the adjustment hole 3121 can be adjusted. In this way, the position of the detection structure 313 is adjusted according to different detection structures 313 or according to different specific height positions of the motion mechanism 32, so that the detection structure 313 is opposite to the nail clamping space 211.

[0050] In some embodiments, the detection structure 313 is a photoelectric sensor, a camera, or a multi-point laser displacement sensor.

[0051] In the embodiment of the present application, the detection structure 313 can be a photoelectric sensor. In this case, the detection structure 313 can be symmetrically arranged on both sides of the nail pulling assembly 2. At this time, the detection structure 313 is relative to the nail clamping space 211 of the nail pulling clamp 21, which means that the detection structure 313 is directed toward the nail clamping space 211 along the ray direction and enables the ray to pass through the nail clamping space 211. By detecting whether the incident light is blocked when it is projected toward the nail clamping space 211 during the movement of the detection structure 313, it is determined whether the nail pulling clamp 21 successfully removes the chemically formed nail. Specifically, it can be determined whether there is a chemically formed nail or not in the nail clamping space 211. The detection structure 313 can also be a camera or a multi-point laser displacement sensor, both of which can obtain image information. The detection structure 313 is relative to the clamping space 211 of the nail pulling clamp 21, which means that the clamping space 211 falls into the image acquisition range of the detection structure 313. At this time, the image information of the clamping space 211 can be obtained through the detection structure 313, and whether there are chemically formed nails in the clamping space 211, and whether the chemically formed nails are intact (if the chemically formed nails are broken or damaged, the chemically formed nails are not intact), so as to directly judge the removal of the chemically formed nails. In some embodiments, the motion mechanism 32 includes a guide structure 321 and a drive structure 322; the guide structure 321 is arranged on the frame 1, and the fixed structure 311 is movably connected to the guide structure 321; the drive structure 322 is respectively connected to the guide structure 321 and the fixed structure 311, so that the detection mechanism 31 moves along the guide structure 321.

[0052] In the embodiment of the present application, the guide structure 321 is used to connect with the fixed structure 311 and provide guidance and limitation for the movement direction of the fixed structure 311. The driving structure 322 is used to provide driving force for the movement of the fixed structure 311 on the guide structure 321, so as to realize the movement of the detection mechanism 31 on the guide structure 321.

[0053] like Figure 4 As shown, in some embodiments, the guide structure 321 may include a base 3211, a guide rail 3212 and a slider 3213, the base 3211 is arranged on the frame 1, the guide rail 3212 is arranged on the base 3211 and extends along the moving direction of the detection mechanism 31, and the slider 3213 is connected to the fixed structure 311; a slide groove 32131 is provided on the side of the slider 3213 away from the fixed structure 311, and the guide rail 3212 is arranged in the slide groove 32131 so that the slider 3213 is slidably connected to the guide rail 3212.

[0054] In the embodiment of the present application, the slide groove 32131 on the slide block 3213 cooperates with the guide rail 3212 to achieve smooth sliding of the slide block 3213 on the guide rail 3212. When the fixed structure 311 is fixed on the slide block 3213, the fixed structure 311 uses the slide block 3213 to achieve sliding on the guide rail 3212.

[0055] It should be noted that the guide rail of the present application is preferably a linear guide rail, so that when the detection structure 313 is relative to the nail clamping space 211 of each nail pulling clamp 21 on the nail pulling assembly 2, the distance between the detection structure 313 and the nail pulling clamp 21 is equal, when the detection structure 313 is a photoelectric sensor, the distance of light propagation is equal, and when the detection structure 313 is a camera or a multi-point laser displacement sensor, the clarity and size of the acquired image are equal.

[0056] It should be noted that the fixed structure 311 is detachably connected to the slider 3213. Since the guide structure 321 requires the slider 3213 to continuously slide on the guide rail 3212, wear and tear will inevitably occur. At this time, with the continuous use of the nail extraction device, the slider 3213 or the guide rail 3212 may need to be replaced. Therefore, the fixed structure 311 slides on the guide rail 3212 through the slider 3213, which can effectively reduce the breakage rate of the fixed structure 311 and reduce maintenance costs.

[0057] like Figure 3-Figure 5 As shown, in some embodiments, the driving structure 322 includes a driving part 3221, a driving wheel 3222, a driven wheel 3223 and a synchronous belt 3224, the driving part 3221 is connected to the base 3211, the driving wheel 3222 is connected to the output end of the driving part 3221, the driven wheel 3223 is connected to the end of the guide structure 321 away from the driving part 3221, and the synchronous belt 3224 is connected to the driving wheel 3222 and the driven wheel 3223; the synchronous belt 3224 is connected to the fixed structure 311 to drive the detection mechanism 31 to move along the guide structure 321.

[0058] In the embodiment of the present application, the driving part 3221 of the driving structure 322 can be a motor. The output end of the motor is connected to the driving wheel 3222, thereby driving the driving wheel 3222 to rotate. The driving wheel 3222 and the driven wheel 3223 are wrapped with a synchronous belt 3224 on the outside. At this time, the driving wheel 3222 rotates to drive the driven wheel 3223 to rotate through the synchronous belt 3224, so that the synchronous belt 3224 can continuously rotate around the driving wheel 3222 and the synchronous wheel. In this process, the fixed structure 311 is connected to the synchronous belt 3224 and is arranged between the driving wheel 3222 and the driven wheel 3223, so that the fixed structure 311 can be driven by the synchronous belt 3224 and move along the guide rail 3212. This driving method has a simple structure and stable movement, and can control the moving speed of the fixed structure 311 according to demand, thereby realizing the rapid detection of the chemically formed nails on the nail removal assembly 2.

[0059] like Figure 4 As shown, in some embodiments, the fixed structure 311 has a through hole 3111 , and the synchronous belt 3224 passes through the through hole 3111 and is connected to the inner wall of the through hole 3111 , so that the fixed structure 311 moves with the synchronous belt 3224 .

[0060] In the embodiment of the present application, by setting a fixing hole in the fixing structure 311 and passing the synchronous belt 3224 through the fixing hole, the volume of the detection component 3 can be reduced in three-dimensional space, and the space occupied can be reduced, which is beneficial to reducing the volume of the nail removal equipment.

[0061] like Figure 1 , Figure 2-Figure 5 As shown, in some embodiments, the motion mechanism 32 also includes at least two position sensors 323, which are relatively arranged at two ends of the guide structure 321 along the extension direction of the guide structure 321 and connected to the guide structure 321; the fixed structure 311 is movably arranged between the at least two position sensors 323.

[0062] In the embodiment of the present application, position sensors 323 are provided at both ends of the guide structure 321, which can limit the limit positions of the starting point and end point of the movement of the detection mechanism 31 on the motion mechanism 32 to prevent the detection mechanism 31 from moving out of control on the guide structure 321.

[0063] Specifically, the position sensor 323 may be a photoelectric sensor. In the embodiment of the present application, there are preferably two position sensors 323, which are respectively arranged at the two ends of the guide rail 3212, and are used to control the moving range of the detection mechanism 31 on the guide rail 3212. When the detection mechanism 31 moves on the guide rail 3212 to the detection range of the position sensor 323, the controller (not shown in the figure) of the nail pulling device controls the driving part to stop, thereby controlling the detection mechanism 31 to stop moving. Among them, the distance between the two position sensors 323 is greater than the distance between the two nail pulling jaws 21 located at the two ends, so that the detection mechanism 31 can detect the nail clamping space 211 of each nail pulling jaw 21.

[0064] like Figure 1 , Figure 2-Figure 5 As shown, in some embodiments, the detection mechanism 31 further includes a trigger element 314, which is connected to the fixed structure 311, and the trigger element 314 can move with the fixed structure 311 to within the sensing range of the position sensor 323 to stop the detection structure 313 from moving.

[0065] In the embodiment of the present application, the trigger element 314 is connected to the fixed structure 311 and moves with the fixed structure 311 on the guide rail 3212. When the fixed structure is moved beyond the detection range and continues to move into the detection range of the position sensor 323, the controller of the nail pulling device receives the position signal through the position sensor 323 and controls the driving part to stop accordingly, thereby controlling the detection mechanism 31 to stop moving, thus avoiding the detection mechanism 31 from moving out of control. This position judgment method has a simple structure, is easy to operate, and has accurate position judgment.

[0066] In addition, the embodiment of the present application may have three position sensors 323, wherein two position sensors 323 are used to protect the starting and ending moving positions of the detection mechanism 31 set at both ends of the guide structure 321, so as to prevent the detection mechanism 31 from slipping out of control out of the guide structure 321, and another position sensor 323 may be set between two adjacent position sensors 323 as the origin of the movement of the detection mechanism 31, so as to facilitate the detection mechanism 31 to reset to the origin after completing the detection, so as to facilitate the detection mechanism 31 to perform a new round of detection.
