[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture.

Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] During the production process of lithium batteries, the electrodes or diaphragms are in the form of strips and are installed in a roll assembly for unwinding and feeding.

[0038] In the related art, the tape splicing equipment includes two roll components and a tape splicing mechanism. The tape splicing mechanism includes a tape cutting part and a gluing part. When the tape of a roll component is almost used up, the tape cutting part cuts off the tape of the roll component, and the gluing part adheres the tape of the other roll component to the cut tape to ensure continuous material supply of the equipment.

[0039] However, before bonding the tape of the roll assembly, the roll assembly needs to be manually pulled to unwind part of the tape for bonding, which is not conducive to improving the automation level of the equipment and has low production efficiency.

[0040] In order to solve the above problems, the present invention proposes a material pulling device 10, which aims to realize automatic pulling of the coil assembly 2 to improve the automation level of the equipment.

[0041] Reference Figures 1 to 11In one embodiment of the present utility model, a winding assembly 2 is provided on one side of the pulling device 10, and the winding assembly 2 is used to install the material tape 91. The end of the material tape 91 is provided with a marking area 911. The pulling device 10 includes a frame 1, a detection assembly 3, a pulling belt assembly 4 and a controller. The detection assembly 3 is connected to the frame 1, and the detection assembly 3 is relatively movable with the material tape 91 installed by the winding assembly 2, so as to be used for circumferentially identifying the marking area 911; the pulling belt assembly 4 includes a first driving assembly 41 and a pulling belt member 43, the first driving assembly 41 is connected to the frame 1, and is transmission-connected to the pulling belt member 43, and the pulling belt member 43 is used to clamp the material tape 91; the controller controls the first driving assembly 41 to drive the pulling belt member 43 to pull the marking area 911 according to the identification information of the detection assembly 3, so as to drive the winding assembly 2 to unwind the material tape 91.

[0042] After the material strip 91 is mounted on the reel assembly 2, the position of the marking area 911 of the material strip 91 is unknown. Therefore, the detection assembly 3 is relatively movable with the material strip 91 mounted on the reel assembly 2, so that the detection assembly 3 can identify the marking area 911 of the material strip 91. The marking area 911 can be set as an identification code, or the marking area 911 can be set to form a color difference with the material strip 91 for identification by the detection assembly 3.

[0043] In one embodiment of the movable arrangement of the detection component 3, the detection component 3 is connected to the movable end of a robot arm or other driving component to move circumferentially relative to the roll, thereby determining the position of the marking area 911 of the roll.

[0044] In the technical solution of the present invention, after the material strip 91 is installed on the material roll assembly, the detection assembly 3 on one side detects the marking area 911 of the material strip 91. After the detection assembly 3 detects the marking area 911, it sends the identification information to the controller. After the controller determines the coordinate position of the marking area 911 of the material strip 91 based on the identification information, it controls the first drive assembly 41 to drive the pull member 43 to pull the marking area 911. The material strip 91 can be pulled to a specified position for subsequent material strip 91 processing.

[0045] Therefore, the solution of the present invention avoids manually pulling the coil assembly 2, and instead drives the coil assembly 2 to unwind the coil 91 by automatically pulling the pull assembly 4, which is beneficial to improving the degree of automation of the equipment and having higher production efficiency.

[0046] Reference Figure 4 In one embodiment of the present invention, the coil assembly 2 is provided with a rotating drive end 211, and the rotating drive end 211 is transmission-connected to the material belt 91 to drive the material belt 91 to rotate circumferentially.

[0047] The coil assembly 2 is provided with a rotating drive member 21 , and the rotating drive member 21 is provided with a rotating drive end 211 . The material strip 91 is sleeved on the rotating drive end 211 for rotation, and the material strip 91 is unwound through the guide roller 23 .

[0048] In this embodiment, after the material strip 91 is mounted on the material roll assembly, the material roll assembly 2 drives the material strip 91 to rotate via the rotating drive end 211. During the rotation of the material strip 91, the detection assembly 3 on one side detects the marking area 911 of the material strip 91. Therefore, this solution drives the material roll to rotate via the rotating drive end 211 of the material roll assembly, thereby facilitating the detection assembly 3 to detect and locate the marking area 911, thereby improving production efficiency.

[0049] Reference Figure 5 In one embodiment of the present invention, the detection component 3 includes a detection cylinder 31 and an identification component 33. The detection cylinder 31 is connected to the frame 1, and the identification component 33 is connected to the telescopic part of the detection cylinder 31 so as to be movable in a direction close to or away from the coil component 2.

[0050] In this embodiment, the identification member 33 can adjust the identification distance with the coil assembly 2 under the drive of the telescopic part of the detection cylinder 31 to meet the identification requirements of the detection assembly 3 for coils of different sizes.

[0051] Reference Figure 5 In one embodiment of the present invention, the identification component 33 includes a rangefinder 331 and a camera 333. The rangefinder 331 and the camera 333 are arranged at intervals on the detection cylinder 31 along the moving direction of the telescopic part of the detection cylinder 31. The rangefinder 331 is arranged on a side close to the coil assembly 2.

[0052] In this embodiment, the target distance is determined by calculating the round-trip time or phase difference of the light beam emitted by the rangefinder 331 after it hits the surface of the web and then reflects back to the receiver. Furthermore, the camera 333 captures images and uses image processing algorithms to identify the marking area 911. This facilitates precise positioning of the web marking area 911 and optimizes the recognition accuracy of the recognition component.

[0053] Reference Figure 3 and Figure 10In one embodiment of the present invention, the pulling belt member 43 includes a second driving component 431, a first suction belt portion 433 and a first pressing belt portion 435. The second driving component 431 is transmission-connected to the first driving component 41. The first suction belt portion 433 adsorbs the marking area 911 under the drive of the second driving component 431. The first pressing belt portion 435 presses the other side of the marking area 911 under the drive of the second driving component 431 and pulls the material belt 91 under the drive of the first driving component 41.

[0054] In this embodiment, the pulling member 43 is driven by the first driving component 41 to move to the front of the marking area 911 of the material roll, and the marking area 911 of the material tape 91 is adsorbed by the first suction belt part 433 to preliminarily separate the material tape 91 in the marking area 911 from the material roll, and then the first pressing belt part 435 presses the side of the material tape 91 away from the first suction belt part 433, which is conducive to achieving stable clamping of the material tape 91.

[0055] Optionally, there are multiple first suction belt parts 433, and the multiple first suction belt parts 433 are arranged at intervals along the adsorption direction perpendicular to the material belt 91 and corresponding to one of the pressing belt parts, which is beneficial to further improve the clamping stability of the material belt 91.

[0056] Reference Figure 3 and Figure 10 In one embodiment of the present invention, the second driving assembly 431 includes a mounting frame 4311, a first translation cylinder 4313, a second translation cylinder 4314 and a third translation cylinder 4315. The mounting frame 4311 is connected to the frame 1, the first translation cylinder 4313 and the second translation cylinder 4314 are respectively connected to the mounting frame 4311, the first belt suction portion 433 is connected to the telescopic portion of the first translation cylinder 4313 to move toward or away from the material belt 91, the third translation cylinder 4315 is connected to the telescopic portion of the second translation cylinder 4314 to move along the telescopic direction perpendicular to the telescopic direction of the telescopic portion of the first translation cylinder 4313, the first belt pressing portion 435 is connected to the telescopic portion of the third translation cylinder 4315 to move in the telescopic direction parallel to the telescopic direction of the telescopic portion of the first translation cylinder 4313 to press the side of the marking area 911 away from the first belt suction portion 433.

[0057] In this embodiment, each translation cylinder is connected to the mounting frame 4311. When the first suction belt portion 433 sucks the material belt 91, the first pressing belt portion 435, driven by the second translation cylinder 4314, avoids the suction direction of the first suction belt portion 433, allowing the first suction belt portion 433 to suck the material belt 91. After the first suction belt portion 433 sucks the material belt 91, the first pressing belt portion 435, driven by the second translation cylinder 4314, moves back to the suction direction of the first suction belt portion 433 and, driven by the translation of the third translation cylinder 4315, presses against the side of the material belt 91 facing away from the first suction belt portion 433. This solution is provided with multiple cylinders to achieve the coordination of the various movements of the first suction belt portion 433 and the first pressing belt portion 435, thereby meeting the pulling requirements of the pulling member 43 and reducing the volume of the pulling member 43.

[0058] Reference Figure 11 In one embodiment of the present invention, the second driving assembly 431 also includes a guide rail 4316, which is connected to the mounting frame 4311 and extends along the telescopic direction of the telescopic part of the second translation cylinder 4314, and the telescopic part of the second translation cylinder 4314 is slidably connected to the guide rail 4316.

[0059] In this embodiment, the telescopic part of the second translation cylinder 4314 is slidably connected to the guide rail 4316, so that the third translation cylinder 4315 can be precisely displaced along the telescopic direction perpendicular to the telescopic part of the first translation cylinder 4313, thereby ensuring that the first pressing belt part 435 can be aligned with the first suction belt part 433, which is beneficial to ensure the stability of the clamping of the material belt 91 by the pulling belt part 43.

[0060] Reference Figure 9 In one embodiment of the present utility model, the first driving component 41 includes a first linear module 411, a second linear module 413, and a rotating module 415. The first linear module 411 is connected to the frame 1, and the second linear module 413 is connected to the translation part of the first linear module 411 to translate along the vertical direction. The rotating module 415 is connected to the translation part of the second linear module 413 to translate perpendicular to the direction. The pull belt member 43 is connected to the rotating part of the rotating module 415 to rotate around a direction perpendicular to the vertical direction.

[0061] In this embodiment, the pulling member 43 is driven by the first linear module 411, the second linear module 413 and the rotating module 415 to pull the tape along the first traction channel 481 and the second traction channel 483 respectively, so as to satisfy the pulling member 43 to pull the material rolls at various positions, thereby further meeting the needs of process production and improving production efficiency.
