Description

一种入料机构、入料装置及卷绕设备A feeding mechanism, feeding device and winding equipment 技术领域Technical field
本申请涉及电池生产设备的技术领域，特别是涉及一种入料机构、入料装置及卷绕设备。This application relates to the technical field of battery production equipment, and in particular to a feeding mechanism, feeding device and winding equipment.
背景技术Background technique
电池的电芯制备过程中，需要利用卷针对极片料带和隔膜进行卷绕，以在卷针上形成电芯。目前，随着电池生产技术的进步和市场需求的爆发式增长等，对于电芯卷绕的生产效率提出了更高的要求。During the cell preparation process of the battery, it is necessary to use a winding needle to wind the electrode strip and separator to form a cell on the winding needle. At present, with the advancement of battery production technology and the explosive growth of market demand, higher requirements have been put forward for the production efficiency of battery core winding.
为了提高电芯的生产效率，本申请的发明人创造性的提出可在一个卷针上同时卷绕成型多个电芯，例如同时卷绕成型两个电芯。为了实现一个卷针上同时卷绕成型两个电芯的构想，本申请的发明人利用入料机构将两条并排的极片料带同时送入卷针，使得卷针能够同时对两条极片料带进行卷绕，并卷绕形成两个电芯。In order to improve the production efficiency of electric cores, the inventor of the present application creatively proposed that multiple electric cores can be rolled and formed on a rolling needle at the same time, for example, two electric cores can be rolled and formed at the same time. In order to realize the concept of winding and forming two electric cores on a rolling needle at the same time, the inventor of this application uses a feeding mechanism to feed two side-by-side pole piece strips into the rolling needle at the same time, so that the rolling needle can simultaneously roll two poles.

Due to factors such as space and winding needle length, the two pole piece strips need to be placed side by side with a small distance between them. Therefore, the space for arranging two correction mechanisms side by side on the feeding mechanism is limited, resulting in two The pole strips are easy to interfere with each other when performing correction operations, and it is difficult to debug the equipment.

The clamping mechanism 10 is arranged upstream of the feeding mechanism 40 and can controllably clamp each strip of material passing by, and can also controllably move closer to the feeding mechanism 40 along the first direction The material belt is fed into the feeding mechanism 40. The cutting mechanism 20 is arranged between the pinching mechanism 10 and the feeding mechanism 40, and can controllably cut each strip of material passing through. The feeding mechanism 40 is used to feed each strip of material downstream into the winding needle.
上述入料装置，在实际卷绕作业过程中，各条料带依次穿过夹送机构10、裁切机构20和入料机构40，并进入卷针。卷针旋转，以对各条料带分别进行卷绕，即在卷针上至少两条料带被分别卷绕成型至少两个电芯。During the actual winding operation of the above-mentioned feeding device, each strip of material passes through the pinching mechanism 10, the cutting mechanism 20 and the feeding mechanism 40 in sequence, and enters the winding needle. The winding needle rotates to wind each strip of material respectively, that is, at least two strips of material are respectively wound on the winding needle to form at least two electric cores.
当卷针上的各个电芯快要卷绕完成时，需要进行收尾作业：首先，夹送机构10夹持途经的各条料带，裁切机构20切断途经的各条料带。然后，卷针继续卷绕，直至将切断的料带全部卷绕完成(即进行收尾)，此时完成收尾作业。 再次进行卷绕时需要进行入料作业：首先，夹送机构10沿第一方向X朝向入料机构40靠近移动，以带动各条料带的切断端穿过裁切机构20而进入入料机构40。然后，夹送机构10松开各条料带，并返回至初始位置。入料机构40将各条料带***至新的卷针上，该新的卷针旋转，以分别对各条料带进行卷绕，并按照上述步骤完成卷绕作业。When each battery core on the winding needle is about to be wound, finishing operations need to be performed: first, the pinching mechanism 10 clamps each passing material strip, and the cutting mechanism 20 cuts each passing material strip. Then, the winding needle continues to wind until all the cut strips are wound (that is, finishing), at which point the finishing operation is completed. When winding again, a feeding operation is required: first, the pinching mechanism 10 moves closer to the feeding mechanism 40 along the first direction X to drive the cut end of each strip of material to pass through the cutting mechanism 20 and enter the feeding mechanism 40. Then, the pinching mechanism 10 releases each strip of material and returns to the original position.

In the embodiment of the present application, the feeding mechanism 40 includes at least two deviation-correcting feeding assemblies 41 corresponding to the above-mentioned at least two material belts. Each deviation correction feeding assembly 41 includes a deviation correction movable seat 410 and a feeding pair roller 411 .

The feeding pair roller 411 is arranged on the deviation correction movable seat 410, and is used to transport the corresponding material strip downstream to the winding needle, so that the winding needle can be wound. Among them, in the first direction X, the feeding rollers 411 of each deviation-correcting feeding assembly 41 are arranged at intervals.

上述入料机构40，在进行入料时，夹送机构10夹持各条料带，裁切机构20将途经的各条料带切断。夹送机构10沿第一方向X靠近入料机构40移动，直至带动各条料带的切断端穿过裁切机构20而到达各个入料对辊411处，使得各条料带的切断端分别进入对应的入料对辊411。然后，控制各个纠偏入料组件41的纠偏活动座410分别沿第二方向Y移动，从而带动入料对辊411及进入入料对辊411的料带沿第二方向Y移动，即实现对料带在第二方向Y上的纠偏。纠偏到位后，各个入料对辊411分别将对应的料带向下游输送至卷针上，即完成一次入料。When the above-mentioned feeding mechanism 40 is feeding, the pinching mechanism 10 clamps each strip of material, and the cutting mechanism 20 cuts each passing strip of material. The pinching mechanism 10 moves close to the feeding mechanism 40 along the first direction Enter the corresponding feeding pair roller 411. Then, the deviation-correction movable seats 410 of each deviation-correction feeding assembly 41 are controlled to move along the second direction Y respectively, thereby driving the feeding pair roller 411 and the material belt entering the feeding pair roller 411 to move along the second direction Y, that is, realizing the material alignment. The belt is corrected in the second direction Y. After the deviation correction is in place, each feeding pair roller 411 transports the corresponding material strip downstream to the winding needle, thereby completing one feeding.
如此，由于各个入料对辊411在第二方向Y上间隔排布，使得各个入料对辊411分别与对应的料带在第一方向X上对齐，进而使得各条料带均能够准确地分别进入到对应的入料对辊411。由于各个入料对辊411在第一方向X间隔布 设，从而使得各个入料对辊411在第二方向Y上不对齐，因此各个入料对辊411沿第二方向Y移动而进行纠偏时不会相互干扰，并且有利于增大对各个入料对辊411进行调试的空间，降低了调试难度。In this way, since each feeding pair roller 411 is arranged at intervals in the second direction Y, each feeding pair roller 411 is aligned with the corresponding material belt in the first direction X, so that each material belt can be accurately Enter the corresponding feeding rollers 411 respectively. Since each feeding pair roller 411 is spaced in the first direction It is assumed that each feeding pair roller 411 is not aligned in the second direction Y. Therefore, each feeding pair roller 411 will not interfere with each other when moving along the second direction Y to correct the deviation, and it is beneficial to increase the accuracy of each feeding pair. The space for debugging the roller 411 reduces the difficulty of debugging.
在一些实施例中，每一入料对辊411包括均设置在纠偏活动座410上的固定辊4110和活动辊4112。该固定辊4110和活动辊4112均相对纠偏活动座410可旋转。活动辊4112与固定辊4110之间形成供对应的料带穿过的入料通道，且其中至少一者相对另一者可靠近或远离。如此，夹送机构10将各条料带分别送入对应的入料对辊411的活动辊4112与固定辊4110之间入料通道之后，可通过活动辊4112与固定辊4110对料带进行夹持。In some embodiments, each feeding pair of rollers 411 includes a fixed roller 4110 and a movable roller 4112 that are both arranged on the deviation correction movable seat 410 . Both the fixed roller 4110 and the movable roller 4112 are rotatable relative to the deviation correction movable seat 410 . An inlet channel for corresponding material strips to pass through is formed between the movable roller 4112 and the fixed roller 4110, and at least one of them can be closer or farther away from the other. In this way, after the pinching mechanism 10 sends each strip of material into the feeding channel between the movable roller 4112 and the fixed roller 4110 of the corresponding feeding roller 411, the material strip can be clamped by the movable roller 4112 and the fixed roller 4110. hold.

In this way, after the pinching mechanism 10 sends the cut ends of each strip of material into the feeding channel between the fixed roller 4110 and the movable roller 4112 of each feeding pair roller 411, it controls the movement of each movable bracket 417 respectively, so that The movable roller 4112 of each feed pair roller 411 moves close to the fixed roller 4110 until the movable roller 4112 of each feed pair roller 411 and the fixed roller 4110 clamp the cut end of the material strip. Then, each deviation correction movable seat 410 is controlled to move along the second direction Y, thereby realizing deviation correction for each strip of material. After the deviation correction is in place, each rotary drive member 413 drives the fixed roller 4110 of each feed roller 411 to rotate, thereby driving each strip of material to be transported downstream through friction (at this time, the movable roller 4112 is also driven to rotate, and interacts with the fixed roller 4110 (the direction of rotation is opposite) until each strip of material The cut end of the tape is inserted into the rolling needle. After the coiling needles are inserted into the cut ends of each strip of material, each movable bracket 417 drives the movable roller 4112 of each feeding pair roller 411 to move away from the fixed roller 4110, so that the fixed roller 4110 and the movable roller of each feeding pair roller 411 Roller 4112 loosens the material belt.

The fixed clamp roller bracket 15 is fixedly connected to the pinch installation frame 11 , and the movable clamp roller bracket 16 is movably connected to the pinch installation frame 11 . The clamping driver 19 is provided on the clamping installation frame 11 and is connected with the movable clamp roller bracket 16 to drive the movable clamp roller bracket 16 to move closer to or away from the fixed clamp roller bracket 15 . One of the nip rollers 12 is rotatably connected to the fixed nip roller bracket 15, and the other nip roller 12 is rotatably connected to the movable nip roller bracket 16, so that driven by the clamping driver 19, the movable nip roller bracket 16 can drive the nip roller 12 on it close to or away from the nip roller 12 on the fixed nip roller bracket 15, so that the two nip rollers 12 clamp or loosen each strip of material.

当滚轮14与楔形块18抵接配合时，在楔形块18施加给滚轮14的抵接力的作用下，滚轮14通过导向杆131带动活动夹辊支架16远离固定夹辊支架15，使得两个夹辊12彼此远离而松开各条料带。如此，夹送安装架11位于初始位置时，滚轮14与楔形块18抵接配合，两个夹辊12处于松开各条料带的状态。此时，夹持驱动件19始终对活动夹辊支架16施加驱动力，使得活动夹辊支架16具有朝向固定夹辊支架15移动的运动趋势。在夹送安装架11沿第一方向X朝向入料机构40靠近移动的过程中，当滚轮14与楔形块18分离时(此时夹送安装架11的移动速度与各条料带的输送速度相同)，在夹持驱动件19提供的驱动力的作用下活动夹辊支架16立即朝向固定夹辊支架15移动，直至两个夹辊12夹持各条料带。When the roller 14 is in contact with the wedge block 18, under the action of the contact force exerted by the wedge block 18 on the roller 14, the roller 14 drives the movable clamp roller bracket 16 away from the fixed clamp roller bracket 15 through the guide rod 131, so that the two clamps The rollers 12 move away from each other to loosen the respective strips of material. In this way, when the pinching installation frame 11 is in the initial position, the roller 14 is in contact with the wedge block 18, and the two pinch rollers 12 are in a state of loosening each strip of material. At this time, the clamping driving member 19 always exerts a driving force on the movable clamp roller bracket 16 , so that the movable clamp roller bracket 16 has a tendency to move toward the fixed clamp roller bracket 15 . During the process of the pinching mounting frame 11 moving closer to the feeding mechanism 40 along the first direction Same), under the action of the driving force provided by the clamping driving member 19, the movable clamp roller bracket 16 immediately moves toward the fixed clamp roller bracket 15 until the two clamp rollers 12 clamp each strip of material.
如此，滚轮14与楔形块18的设置，使得当滚轮14与楔形块18分离时活动夹辊支架16能够立即朝向固定夹辊支架15移动，从而立即带动两个夹辊12夹持各条料带，大大缩短了两个夹辊12由松开状态至夹持状态的响应时间。In this way, the arrangement of the roller 14 and the wedge block 18 enables the movable clamp roller bracket 16 to immediately move toward the fixed clamp roller bracket 15 when the roller 14 and the wedge block 18 are separated, thus immediately driving the two clamp rollers 12 to clamp each strip of material. , greatly shortening the response time of the two clamping rollers 12 from the loosened state to the clamped state.
进一步地，两个夹板17的其中一个夹板17固定连接在固定夹辊支架15上，其中另一个夹板17固定连接在活动夹辊支架16上，从而当活动夹辊支架16带动两个夹辊12夹持各条料带的同时，也带动两个夹板17夹持各条料带；当活动夹辊支架16带动两个夹辊12松开各条料带的同时，也带动两个夹板17松开各条料带。Furthermore, one of the two clamping plates 17 is fixedly connected to the fixed clamping roller bracket 15 , and the other clamping plate 17 is fixedly connected to the movable clamping roller bracket 16 , so that when the movable clamping roller bracket 16 drives the two clamping rollers 12 While clamping each strip of material, it also drives the two clamping plates 17 to clamp each strip of material; when the movable clamp roller bracket 16 drives the two clamping rollers 12 to loosen each strip of material, it also drives the two clamping plates 17 to loosen each strip of material. Open each strip of material.

Complete the cutting action. Alternatively, the cutting driving member 223 may be a motor.
具体到实施例中，裁切组件21还包括第二导柱215、压料块216及压料弹性件217。第二导柱215沿第三方向Z可移动地连接在活动切刀座212上。压料块216固定连接在第二导柱215上，且压料弹性件217抵接在压料块216与活动切刀座212之间。如此，在活动切刀座212沿第三方向Z带动活动切刀213和压料块216朝向固定切刀211移动的过程中，首先压料块216在压料弹性件217提供的弹力作用下将各条料带压紧在裁切安装架210上，然后活动切刀213再配合固定切刀211将各条料带切断。也就是说，在将各条料带切断之前利用压料块216将各条料带压紧，从而有利于提高裁切质量。可选地，压料弹性件217可以是弹簧。Specifically in this embodiment, the cutting assembly 21 also includes a second guide post 215, a pressing block 216 and a pressing elastic member 217. The second guide post 215 is movably connected to the movable cutter base 212 along the third direction Z. The pressing block 216 is fixedly connected to the second guide post 215, and the pressing elastic member 217 is in contact between the pressing block 216 and the movable cutter seat 212. In this way, in the process that the movable cutter base 212 drives the movable cutter 213 and the pressing block 216 to move toward the fixed cutter 211 along the third direction Z, first the pressing block 216 moves the pressing block 216 under the elastic force provided by the pressing elastic member 217. Each strip of material is pressed on the cutting installation frame 210, and then the movable cutter 213 cooperates with the fixed cutter 211 to cut each strip of material. That is to say, before cutting each strip of material, the pressing block 216 is used to compress each strip of material, which is beneficial to improving the cutting quality. Optionally, the pressing material elastic member 217 may be a spring.
具体到实施例中，裁切安装架210可受控地沿第一方向X朝向入料机构40靠近或远离移动。如此，在实际卷绕作业过程中，各条料带依次穿过夹送机构10、裁切机构20和入料机构40，并进入卷针。卷针旋转，以分别对各条料带进行卷绕，即在卷针上至少两条料带被卷绕成型至少两个电芯。Specifically in the embodiment, the cutting mounting frame 210 can be controlled to move closer to or away from the feeding mechanism 40 along the first direction X. In this way, during the actual winding operation, each strip of material passes through the pinching mechanism 10, the cutting mechanism 20 and the feeding mechanism 40 in sequence, and enters the winding needle. The winding needle rotates to wind each strip of material respectively, that is, at least two strips of material are wound on the winding needle to form at least two electric cores.
当卷针上的各个电芯快要卷绕完成时，需要进行收尾作业：首先，控制夹送安装架11沿第一方向X朝向入料机构40靠近移动，并逐渐加速，直至夹送安装架11的移动速度与各条料带的输送速度相同(即夹送安装架11与各条料带相对静止)。此时，滚轮14与楔形块18分离，使得活动夹辊支架16在夹持驱动件19提供的驱动力的作用下朝向固定夹辊支架15移动，直至两个夹辊12和两个夹板17均夹持各条料带。同时，控制裁切安装架210沿第一方向X朝向入料机构40移动，并逐渐加速，直至裁切安装架210与各条料带的输送速度相 同(即裁切安装架210与各条料带相对静止)。此时，在裁切驱动件223的驱动下活动切刀213与固定切刀211配合切断途经的各条料带。然后，卷针继续卷绕，直至将切断的料带全部进行卷绕，此时完成首尾作业。When each battery core on the winding needle is about to be wound, finishing operations need to be performed: first, control the pinching and feeding mounting bracket 11 to move closer to the feeding mechanism 40 along the first direction X, and gradually accelerate until the pinching and feeding mounting bracket 11 The moving speed is the same as the conveying speed of each material belt (that is, the pinching installation frame 11 and each material belt are relatively stationary). At this time, the roller 14 is separated from the wedge block 18, so that the movable clamp roller bracket 16 moves toward the fixed clamp roller bracket 15 under the driving force provided by the clamping driving member 19, until the two clamp rollers 12 and the two clamp plates 17 are both Clamp each strip. At the same time, the cutting mounting frame 210 is controlled to move toward the feeding mechanism 40 along the first direction X, and gradually accelerates until the cutting mounting frame 210 is consistent with the conveying speed of each material belt. (that is, the cutting installation frame 210 and each strip of material are relatively stationary). At this time, driven by the cutting driver 223, the movable cutter 213 cooperates with the fixed cutter 211 to cut each strip of material passing through. Then, the winding needle continues to wind until all the cut strips are wound, at which point the first and last operations are completed.
再次进行卷绕时需要进行入料作业：首先，夹送机构10继续沿第一方向X朝向入料机构40靠近移动，以带动各条料带的切断端穿过裁切机构20而进入入料机构40的各个入料对辊411，且各条料带的切断端均被对应的入料对辊411的固定辊4110和活动辊4112夹持。然后，夹持驱动件19驱动两个夹辊12和两个夹板17均松开各条料带，且控制夹送安装架11和裁切安装架210均返回至各自的初始位置。入料机构40的各个入料对辊411分别将各条料带送入至新的卷针上，该新的卷针旋转，以分别对各条料带进行卷绕，并按照上述步骤完成卷绕。When winding again, a feeding operation is required: first, the pinching mechanism 10 continues to move closer to the feeding mechanism 40 along the first direction Each feeding pair roller 411 of the mechanism 40 and the cut end of each material strip are clamped by the fixed roller 4110 and the movable roller 4112 of the corresponding feeding pair roller 411. Then, the clamping driving member 19 drives the two clamping rollers 12 and the two clamping plates 17 to loosen each strip of material, and controls the clamping installation frame 11 and the cutting installation frame 210 to return to their respective initial positions. Each feeding pair roller 411 of the feeding mechanism 40 feeds each strip of material to a new winding needle, and the new winding needle rotates to wind each strip of material respectively, and completes the winding according to the above steps. around.
请参见图1及图2所示，进一步地，入料装置还包括第二驱动机构60，裁切安装架210沿第一方向X可移动地连接在基座上。第二驱动机构60设置在该基座上，并与裁切安装架210连接，以驱动裁切安装架210沿第一方向X移动。Referring to FIGS. 1 and 2 , further, the feeding device further includes a second driving mechanism 60 , and the cutting mounting frame 210 is movably connected to the base along the first direction X. The second driving mechanism 60 is disposed on the base and connected with the cutting mounting frame 210 to drive the cutting mounting frame 210 to move along the first direction X.

The second screw rod is rotatably connected to the base, and the axial direction of the second screw rod is parallel to the first direction X. The second driving member is disposed on the base and connected with the second screw rod, so that the second driving member can drive the second screw rod to rotate. The second screw nut is threadedly connected to the second screw nut and is fixedly connected to the cutting mounting bracket 210 so that the cutting mounting bracket 210 and the second screw nut move together. In this way, when the second driving member drives the second screw rod to rotate, the second screw rod drives the second screw rod nut to move along the first direction X, and the second screw nut drives the cutting mounting bracket 210 to move along the first direction X. Alternatively, the second driving member may be a motor.

需要说明的是，本申请的发明人在实际生产中发现，卷针同时卷绕成型的至少两个电芯的料带卷绕长度经常存在差异，导致生产的电芯的质量一致性较差(即对于所包含的极片料带卷绕长度较短的电芯，所包含的极片料带上的活性物质的量较少，导致该电芯的性能较差)。本申请的发明人研究发现，导致同时卷绕成型的各个电芯的料带卷绕长度存在差异主要是由于各条料带和/或隔膜的厚度尺寸存在偏差所造成的。具体分析如下：各个电芯均跟随同一卷针旋转而卷绕成型，因此同一卷针上的各个电芯卷绕的圈数是相同的，由于各条料带和/或隔膜的厚度不一，从而导致在卷绕相同圈数的条件下各个电芯的料带卷绕长度不一。在卷针上同时卷绕成型(即卷绕相同圈数)的各个电芯中，由厚度较厚的料带和/或隔膜形成的电芯，其料带卷绕长度更长；由厚度较薄的料带和/或隔膜形成的电芯，其料带卷绕长度更短。It should be noted that the inventor of the present application found in actual production that the winding lengths of at least two battery cores formed by winding needles at the same time often differ, resulting in poor quality consistency of the produced battery cores ( That is, for an electric core that contains a pole piece material tape with a shorter winding length, the amount of active material on the pole piece material tape included is smaller, resulting in poorer performance of the battery core). The inventor of the present application found through research that the difference in the winding length of the strips of each battery core that is rolled and formed at the same time is mainly caused by the deviation in the thickness and size of each strip and/or separator. The specific analysis is as follows: Each battery core is wound and formed following the rotation of the same winding needle. Therefore, the number of winding turns of each battery core on the same winding needle is the same. Since the thickness of each strip and/or separator is different, As a result, the winding lengths of the tapes of each battery core are different under the same number of windings. Among the various battery cores that are wound simultaneously on the winding needle (that is, wound with the same number of turns), the battery core formed by a thicker material tape and/or separator has a longer tape winding length; Cells formed from thinner tapes and/or separators have shorter tape winding lengths.
为了解决卷针上同时卷绕成型的各个电芯的料带卷绕长度不一致，导致各个电芯的质量一致性较差的问题。本申请的发明人创造性的在裁切机构20与入料机构40之间设置补偿机构30，并通过补偿机构30独立调节各条料带途经补偿机构30的长度，从而对卷针上的各个电芯所包含的料带卷绕长度进行补偿，使得卷绕完成后的各个电芯所包含的料带卷绕长度一致，进而确保各个电芯的质量一致性较佳。In order to solve the problem of inconsistent winding lengths of the material strips of each battery core that are wound and formed on the winding needle at the same time, resulting in poor quality consistency of each battery core. The inventor of the present application creatively sets up a compensation mechanism 30 between the cutting mechanism 20 and the feeding mechanism 40, and independently adjusts the length of each strip passing through the compensation mechanism 30 through the compensation mechanism 30, thereby adjusting each electric current on the winding needle. The winding length of the material tape contained in the core is compensated so that the winding length of the material tape contained in each battery core is consistent after the winding is completed, thereby ensuring better quality consistency of each battery core.
请参见图9至图11，本申请的实施例中，入料装置还包括补偿机构30，该补偿机构30布置在裁切机构20与入料机构40之间，即该补偿机构30位于裁切机构20的下游，且位于入料机构40的上游。补偿机构30包括与上述至少两条料带一一对应的至少两个补偿组件32。每一补偿组件32具有补偿通道和施力 部，该补偿通道用于供对应的料带穿过。施力部用于对途经该补偿通道的料带施加作用力，使得途经该补偿通道的料带在该作用力的作用下改变输送路径，以增加位于该补偿通道内的料带的长度，以对对应的电芯所包含的料带卷绕长度进行补偿。Please refer to Figures 9 to 11. In the embodiment of the present application, the feeding device also includes a compensation mechanism 30. The compensation mechanism 30 is arranged between the cutting mechanism 20 and the feeding mechanism 40. That is, the compensation mechanism 30 is located at the cutting mechanism. Downstream of the mechanism 20 and upstream of the feeding mechanism 40 . The compensation mechanism 30 includes at least two compensation components 32 corresponding to the above-mentioned at least two material belts. Each compensation component 32 has a compensation channel and a force application part, the compensation channel is used for the corresponding material belt to pass through. The force applying part is used to exert force on the material belt passing through the compensation channel, so that the material belt passing through the compensation channel changes the conveying path under the action of the force, so as to increase the length of the material belt located in the compensation channel, so as to Compensate for the winding length of the tape contained in the corresponding battery core.
在实际使用时，各条料带依次穿过夹送机构10、裁切机构20、补偿机构30和入料机构40，进而卷绕在卷针上。当卷针上的各个电芯快要卷绕完成时，夹送机构10和裁切机构20沿第一方向朝向入料机构40加速移动，直至夹送机构10和裁切机构20的速度与各条料带的输送速度相等。此时，夹送机构10夹持途经的各条料带，裁切机构20将途经的各条料带切断。卷针继续进行卷绕，直至将各条料带的尾端完全卷绕至卷针上(即进行收尾)，此时即完成了一次卷绕作业。In actual use, each strip of material passes through the pinching mechanism 10, the cutting mechanism 20, the compensation mechanism 30 and the feeding mechanism 40 in sequence, and then is wound on the winding needle. When each battery core on the winding needle is about to be wound, the pinching mechanism 10 and the cutting mechanism 20 accelerate and move toward the feeding mechanism 40 in the first direction until the speed of the pinching mechanism 10 and the cutting mechanism 20 matches the speed of each strip. The conveying speed is equal. At this time, the pinching mechanism 10 clamps each passing material strip, and the cutting mechanism 20 cuts each passing material strip. The winding needle continues to wind until the tail end of each strip of material is completely wound onto the winding needle (that is, the winding operation is finished). At this time, a winding operation is completed.
上述入料装置，在裁切机构20将各条料带切断之前，可通过控制各个补偿组件32的施力部分别对途经补偿通道的料带施加作用力，从而分别调整途经各个补偿通道的料带的长度，使得当裁切机构20切断各条料带时，卷针上的各个电芯自身已经卷绕的料带长度与卷针至裁切机构20之间的料带长度之和均相等，进而使得完成收尾后卷针上的各个电芯所包含的料带卷绕长度一致，确保了各个电芯的质量一致性较佳。The above-mentioned feeding device, before the cutting mechanism 20 cuts each strip of material, can control the force-applying part of each compensation component 32 to exert force on the material strip passing through the compensation channel, thereby adjusting the material passing through each compensation channel respectively. The length of the tape is such that when the cutting mechanism 20 cuts each strip of material, the length of the tape that each cell on the reeling needle has been wound by itself is equal to the sum of the lengths of the tape between the reeling needle and the cutting mechanism 20 , thus making the winding length of the material tape contained in each battery core on the winding needle consistent after completion, ensuring better quality consistency of each battery core.
例如，卷针同时对第一料带和第二料带进行卷绕，从而分别卷绕成型第一电芯和第二电芯。也就是说，第一料带被卷绕在卷针上形成第一电芯，同时第二料带被卷绕在卷针上形成第二电芯。若卷绕成型第一电芯的第一料带和/或隔膜较厚，卷绕成型第二电芯的第二料带和/或隔膜较薄，则进行同步卷绕时第一电芯的料带卷绕长度较长，第二电芯的料带卷绕长度较短。为了对第二电芯的料带卷绕长度进行补偿，在裁切机构20切断第一料带和第二料带之前，可通过 调节相对应的补偿组件32的施力部对途经补偿通道内第二料带施加作用力，使得途经补偿通道的第二料带的输送路径发生变化，进而使得途经该补偿通道的第二料带长度增长。在裁切机构20切断第一料带和第二料带时，第一电芯的已经卷绕的料带长度与卷针和裁切机构20之间第一料带的料带长度之和，大致等于第二电芯已经卷绕的料带长度与卷针和裁切机构20之间第二料带的料带长度之和，进而确保收尾完成后第一电芯和第二电芯所包含的料带卷绕长度大致相等，确保各个电芯的质量一致性较佳。For example, the winding needle winds the first material strip and the second material strip at the same time, thereby winding and forming the first battery core and the second battery core respectively. That is to say, the first material strip is wound around the winding needle to form the first battery core, and at the same time, the second material strip is wound around the winding needle to form the second battery core. If the first strip and/or separator of the first battery core is thicker, and the second strip and/or separator of the second battery core is thinner, then the first battery core will be synchronously wound. The winding length of the material tape is longer, and the winding length of the material tape of the second battery core is shorter. In order to compensate for the winding length of the material tape of the second battery core, before the cutting mechanism 20 cuts the first material tape and the second material tape, the Adjust the force-applying part of the corresponding compensation component 32 to exert force on the second material belt passing through the compensation channel, so that the conveying path of the second material belt passing through the compensation channel changes, and then the second material belt passing through the compensation channel changes. Growth in length. When the cutting mechanism 20 cuts the first material tape and the second material tape, the sum of the length of the rolled material tape of the first battery core and the length of the first material tape between the winding needle and the cutting mechanism 20 is approximately It is equal to the sum of the length of the material tape that the second battery core has been wound and the length of the second material tape between the winding needle and the cutting mechanism 20, thereby ensuring that the material contained in the first battery core and the second battery core after the finishing is completed. The tape winding lengths are approximately equal to ensure better quality consistency of each battery core.
需要说明的是，各个补偿组件32沿第二方向Y间隔布设，使得各个补偿组件32分别与各条料带对齐，进而使得各条料带能够分别进入对应的补偿组件32的补偿通道。It should be noted that each compensation component 32 is spaced apart along the second direction Y, so that each compensation component 32 is aligned with each strip of material, so that each strip of material can enter the compensation channel of the corresponding compensation component 32 respectively.
还需要说明的是，卷绕在卷针上的各个电芯的料带卷绕长度可通过检测器进行实时检测，然后，补偿组件32的施力部根据该检测器检测的料带卷绕长度来调节对料带施加的作用力，进而使得调节途经补偿通道的料带改变输送路径，即调节途经补偿通道的料带的长度，以达到补偿电芯所包含的料带卷绕长度的目的。当然，该检测器的布置位置以及检测器的具体结构，在此不作限定，只要能够对卷针上的各个电芯所包含的料带卷绕长度进行实时检测即可，在此不作限定。It should also be noted that the winding length of each battery core wound on the winding needle can be detected in real time by a detector, and then, the force applying part of the compensation component 32 is based on the winding length of the material tape detected by the detector. To adjust the force exerted on the material belt, thereby adjusting the material belt passing through the compensation channel to change the conveying path, that is, adjusting the length of the material belt passing through the compensation channel, in order to achieve the purpose of compensating the winding length of the material belt contained in the battery core. Of course, the arrangement position of the detector and the specific structure of the detector are not limited here, as long as the winding length of the material strip contained in each cell on the winding needle can be detected in real time, there are no limitations here.
还需要说明的是，施力部对料带施加的作用力可以是施力部直接与料带接触而带动料带改变输送路径的接触作用力。当然，在其他实施例中，施力部对料带施加的作用力也可以是非接触作用力，例如施力部对料带吹气而施加给料带的气压力，也能够带动料带改变输送路径，在此不作限定。It should also be noted that the force exerted by the force applying part on the material belt may be the contact force in which the force applying part directly contacts the material belt and drives the material belt to change the conveying path. Of course, in other embodiments, the force exerted by the force applying part on the material belt can also be a non-contact force. For example, the force applying part blows air on the material belt and applies air pressure to the material belt, which can also drive the material belt to change the conveying path. , not limited here.
在一些实施例中，每一补偿组件32包括沿补偿通道布设的多个过辊。该多个过辊的其中一部分位于料带(即途经补偿通道的料带)的一侧，其中另一部 分位于料带(即途经补偿通道的料带)的相对的另一侧。该多个过辊中的至少一个可受控地朝向途经的料带靠近或远离，以作为上述施力部带动途经的料带改变输送路径，使得途经补偿通道的料带的长度增加。优选地，每一补偿组件32的补偿通道沿第一方向X纵长延伸，即多个过辊沿第一方向X间隔布设，以便于夹送机构10的两个夹板17由各个过辊之间穿过，从而将料带的切断端送入入料机构40。In some embodiments, each compensation assembly 32 includes a plurality of rollers arranged along the compensation channel. One part of the plurality of rollers is located on one side of the material belt (that is, the material belt passing through the compensation channel), and another part of the rollers The points are located on the opposite side of the material belt (that is, the material belt passing through the compensation channel). At least one of the plurality of rollers can controllably move toward or away from the passing material belt, so that the force applying portion drives the passing material belt to change the conveying path, so that the length of the material belt passing through the compensation channel is increased. Preferably, the compensation channel of each compensation assembly 32 extends longitudinally along the first direction X, that is, a plurality of rollers are arranged at intervals along the first direction Pass through, thereby sending the cut end of the material belt into the feeding mechanism 40.
具体到一个实施例中，该多个过辊中至少包括两个固定过辊321和活动过辊323，该两个固定过辊321位于料带的同一侧。活动过辊323位于料带的相对的另一侧。活动过辊323可受控地进入或退出两个固定过辊321之间的空间。当活动过辊323进入两个固定过辊321之间的空间时，活动过辊323作为上述施力部带动途经的料带改变输送路径，使得途经补偿通道的料带的长度增加。Specifically, in one embodiment, the plurality of rollers include at least two fixed rollers 321 and a movable roller 323, and the two fixed rollers 321 are located on the same side of the material belt. The movable roller 323 is located on the opposite side of the material belt. The movable roller 323 can enter or exit the space between the two fixed rollers 321 in a controlled manner. When the movable roller 323 enters the space between the two fixed rollers 321, the movable roller 323 serves as the above-mentioned force applying part to drive the passing material belt to change the conveying path, so that the length of the material belt passing through the compensation channel is increased.
如此，当需要增加途经补偿通道内的料带的长度时，控制活动过辊323朝向进入两个固定过辊321之间的空间移动(即如图9所示的向左移动)，从而使得途经补偿通道内的料带呈“S”形依次绕经上游的固定过辊321、活动过辊323和下游的固定过辊321，且随着活动过辊323的移动距离增大料带呈“S”的弯曲角度越大，从而途经补偿通道的料带的长度越长。当不需要增加途经补偿通道内的料带的长度时，控制活动过辊323退出两个固定过辊321之间的空间移动(即如图9所示的向右移动)，随着活动过辊323的移动距离增大料带呈“S”的弯曲角度越小(即料带越平直)，直至途经补偿通道的料带处于平直状态。需要说明的是，活动过辊323的移动可以是沿直线移动，也可以是沿曲线或折线移动，只要能够进入或退出两个固定过辊321之间的空间即可，在此不作限定。In this way, when it is necessary to increase the length of the material belt passing through the compensation channel, the movable roller 323 is controlled to move toward the space between the two fixed rollers 321 (ie, move to the left as shown in Figure 9), so that the movable roller 323 passes through the compensation channel. The material belt in the compensation channel is in an "S" shape and sequentially winds through the upstream fixed roller 321, the movable roller 323 and the downstream fixed roller 321, and as the moving distance of the movable roller 323 increases, the material belt is in an "S" shape. "The greater the bending angle, the longer the length of the material belt passing through the compensation channel. When there is no need to increase the length of the material belt passing through the compensation channel, the movable roller 323 is controlled to exit the space between the two fixed rollers 321 (ie, move to the right as shown in Figure 9). As the moving distance of 323 increases, the "S" bending angle of the material belt becomes smaller (that is, the material belt becomes straighter) until the material belt passing through the compensation channel is in a straight state. It should be noted that the movement of the movable roller 323 may be along a straight line, or along a curve or a folded line, as long as it can enter or exit the space between the two fixed rollers 321, which is not limited here.
优选地，两个固定过辊321沿第一方向X间隔布设，以便于夹送机构10的 两个夹板17沿第一方向X由两个固定过辊321与活动过辊323之间穿过，从而将料带的起头端送入入料机构40。具体到图9所示的实施例中，料带由上至下依次绕经上面的固定过辊321的右侧、活动过辊323的左侧以及下面的固定过辊321的右侧。如此，当活动过辊323向左移动而进入两个固定过辊321之间的空间时，绕在两个固定过辊321和活动过辊323之间的料带长度增长；当活动过辊323向右移动而退出两个固定过辊321之间的空间时，绕在两个固定过辊321和活动过辊323之间的料带长度变短。Preferably, the two fixed rollers 321 are spaced apart along the first direction X to facilitate the pinching mechanism 10 The two clamping plates 17 pass between the two fixed rollers 321 and the movable roller 323 along the first direction X, thereby feeding the starting end of the material strip into the feeding mechanism 40 . Specifically, in the embodiment shown in FIG. 9 , the material belt passes through the right side of the upper fixed roller 321 , the left side of the movable roller 323 , and the right side of the lower fixed roller 321 from top to bottom. In this way, when the movable roller 323 moves to the left and enters the space between the two fixed rollers 321, the length of the material belt wound between the two fixed rollers 321 and the movable roller 323 increases; when the movable roller 323 When moving to the right to exit the space between the two fixed rollers 321, the length of the material belt wound between the two fixed rollers 321 and the movable roller 323 becomes shorter.
进一步地，补偿机构30还包括补偿安装架31，每一补偿组件32还包括补偿活动支架322。每一补偿组件32的两个固定过辊321均可转动地连接在补偿安装架31上。补偿活动支架322可受控移动地连接在补偿安装架31上，活动过辊323可转动地连接在补偿活动支架322上。如此，将两个固定过辊321和活动过辊323集成设置在补偿安装架31上，进一步提高结构的紧凑程度。并且，补偿活动支架322相对补偿安装架31移动时，能够带动活动过辊323进入或退出两个固定过辊321之间的空间，从而改变料带输送路径，进而实现调节途经补偿通道内的料带的长度。Further, the compensation mechanism 30 also includes a compensation mounting bracket 31 , and each compensation assembly 32 also includes a compensation movable bracket 322 . The two fixed rollers 321 of each compensation assembly 32 are rotatably connected to the compensation mounting frame 31 .

The second transmission belt 3313 is sleeved between the second driving wheel 3312 and the second driven wheel 3314, so that the second driving wheel 3312 can drive the second driven wheel 3314 to rotate through the second transmission belt 3313. The compensation screw nut 3322 is threadedly connected to the compensation screw 3321 and is fixedly connected to the driving block 34 so that the compensation screw nut 3322 can move synchronously with the driving block 34 .

Strap length adjustment.
具体到一个实施例中，补偿组件32的数量为两个，料带的数量为两条。需要说明的是，两条料带沿第二方向Y并排布设，且均沿第一方向X输送，使得两条料带依次经过夹送机构10、裁切机构20、补偿机构30和入料机构40，进而最终卷绕在卷针上，即卷针能够同时卷绕成型两个电芯。在补偿机构30处，两条料带分别由两个补偿组件32的补偿通道穿过，以便于通过改变途经补偿通道的料带的输送路径来调节途经该补偿通道的料带的长度，进而实现对卷针上的各个电芯的料带卷绕长度进行补偿，使得各个电芯的料带卷绕长度一致。Specifically, in one embodiment, the number of compensation components 32 is two, and the number of material strips is two. It should be noted that the two material belts are laid side by side along the second direction Y, and both are transported along the first direction X, so that the two material belts pass through the pinching mechanism 10, the cutting mechanism 20, the compensation mechanism 30 and the feeding mechanism in sequence. 40, and then finally wound on the winding needle, that is, the winding needle can wind and shape two electric cores at the same time. At the compensation mechanism 30, the two material belts pass through the compensation channels of the two compensation assemblies 32 respectively, so that the length of the material belt passing through the compensation channel can be adjusted by changing the conveying path of the material belt passing through the compensation channel, thereby achieving Compensate the winding length of each battery core on the winding needle so that the winding length of each battery core is consistent.
具体到实施例中，补偿安装架31可受控地沿第一方向X朝向裁切机构20靠近或远离，以便于对剔除料带端部的废料段的动作过程进行避让。如此，当需要剔除各条料带端部的废料段时，补偿安装架31沿第一方向X靠近裁切机构20移动至避让位置，以便于废料剔除机构移动进入到补偿机构30与卷针之间的位置，从而使得各条料带的废料段(废料段即为料带的起头段)依次穿过裁切 机构20和对应的补偿组件32的补偿通道，并被同步收卷在废料剔除机构上。当各条料带的废料段均穿过裁切机构20之后，裁切机构20将各条料带同时切断，废料剔除机构继续将被切断的各条废料段收卷完成。当各条料带的废料段均收卷完成后，废料剔除机构退出补偿机构30与卷针之间的位置。当废料剔除机构退出补偿机构30与卷针之间的位置后，补偿安装架31沿第一方向X远离裁切机构20移动至初始位置，以便于在卷针进行卷绕的过程中对各个电芯的料带卷绕长度进行补偿。In specific embodiments, the compensation mounting bracket 31 can controllably move closer or farther away from the cutting mechanism 20 along the first direction In this way, when it is necessary to remove the waste segments at the ends of each strip of material, the compensation mounting frame 31 moves close to the cutting mechanism 20 along the first direction position in between, so that the waste sections of each strip of material (the waste section is the starting section of the strip) pass through the cutting in turn. The compensation channels of the mechanism 20 and the corresponding compensation assembly 32 are synchronously wound on the waste rejection mechanism. After the waste sections of each material strip pass through the cutting mechanism 20, the cutting mechanism 20 cuts each strip of material simultaneously, and the waste removal mechanism continues to wind up the cut waste sections. When the waste sections of each material strip are rolled up, the waste removal mechanism exits the position between the compensation mechanism 30 and the winding needle. After the scrap removal mechanism exits the position between the compensation mechanism 30 and the winding needle, the compensation mounting frame 31 moves away from the cutting mechanism 20 along the first direction The core tape winding length is compensated.
需要说明的是，在废料剔除机构同步收卷各条料带的废料段的过程中，由于各条料带的厚度不一致使得各条料带的废料段的收卷长度会存在差异，导致部分料带的废料段已经全部穿过了裁切机构20的时候，另一部分料带的废料段还未完全穿过裁切机构20。为了确保各条料带的废料段均被完全去除，裁切机构20需要在各条料带的废料段均完全穿过废料段之后才能将各条料带切断，从而必然导致部分料带的良品段也被切除，进而导致料带的浪费。It should be noted that during the process of the waste removal mechanism synchronously winding up the waste sections of each strip, due to the inconsistent thickness of each strip, the winding length of the waste section of each strip will be different, resulting in some materials When all the waste material sections of the tape have passed through the cutting mechanism 20 , the waste material sections of another part of the material tape have not completely passed through the cutting mechanism 20 . In order to ensure that the waste sections of each strip are completely removed, the cutting mechanism 20 needs to cut each strip after the waste sections of each strip have completely passed through the waste section, which will inevitably lead to the defective products of some strips. Segments are also cut off, resulting in wasted material.
为了避免料带的浪费，在废料剔除机构同步收卷各条料带的废料段的过程中，可利用各个补偿组件32对分别收卷在废料剔除机构上的各条料带的收卷长度进行补偿，从而确保各条料带的废料段同时全部穿过裁切机构20，进而确保裁切机构20能够准确地同时切除各条料带的废料段。可以理解的是，各个补偿组件32在废料段收卷过程中的补偿原理与在卷针卷绕过程中的补偿原理相同，故在此不作赘述。In order to avoid the waste of the material tape, when the waste material removal mechanism synchronously winds up the waste sections of each material tape, each compensation component 32 can be used to adjust the winding length of each material tape that is respectively rolled up on the waste material removal mechanism. compensation, thereby ensuring that the waste segments of each strip of material pass through the cutting mechanism 20 at the same time, thereby ensuring that the cutting mechanism 20 can accurately and simultaneously cut off the scrap segments of each strip of material. It can be understood that the compensation principle of each compensation component 32 during the waste section winding process is the same as the compensation principle during the needle winding process, so no further description will be given here.
需要说明的是，废料剔除机构的具体结构以及收卷废料段的具体动作过程，均可采用较为成熟的现有技术，故在此不作赘述。It should be noted that the specific structure of the waste removal mechanism and the specific action process of winding up the waste section can adopt relatively mature existing technologies, so they will not be described in detail here.
