[0002] The tab forming equipment is one of the key pieces of equipment in the lithium-ion battery manufacturing process. It is mainly used to complete processes such as welding, marking, and slitting of tab strips and tab tapes. Its performance directly affects the safety, consistency, and production efficiency of the battery.

[0003] The existing equipment has a complex structure with highly integrated functional modules (such as preheating, welding, cutting, and testing), and tightly intertwined mechanical and electrical systems, making fault diagnosis difficult. The equipment lacks modular design, and partial failures often lead to machine downtime, resulting in high maintenance costs and low efficiency. Summary of the Invention

[0014] In one embodiment, a cutting machine is also included, the cutting machine comprising: Mounting rack; The moving blade module includes a moving blade assembly and a moving blade drive assembly. The moving blade drive assembly is mounted on the mounting bracket, and the moving blade assembly is detachably connected to the output end of the moving blade drive assembly so that the moving blade drive assembly can drive the moving blade assembly to move relative to the mounting bracket. A fixed blade is detachably connected to the mounting bracket. The fixed blade and the moving blade assembly are located on the same side of the mounting bracket. The fixed blade is located between the moving blade assembly and the mounting bracket. A cutting part is provided on the side of the fixed blade facing the moving blade assembly. The cutting part is provided corresponding to the moving blade assembly. When the moving blade assembly moves relative to the mounting bracket, the moving blade assembly and the cutting part move relative to each other and can cut the tab adhesive.

[0020] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0021] Please see Figure 1 and Figure 2 This embodiment provides a tab production equipment, including a conveying device, a glue feeding device 2, a cutting machine 3, a tab punching device 4, a laser marking device 5, and a tab detection device 6.

[0022] Conveying device 1 is used to convey tab adhesive 92. Adhesive feeding device 2 is used to transport tab adhesive 92 to the next workstation. Cutting machine 3 is used to cut the tab adhesive. Tab punching device 4 is located below adhesive feeding device 2 and is used to punch chamfer the tab adhesive 92. Laser marking device 5 is used to laser mark the tabs. Tab detection device 6 is located below tab punching device and is used to detect insufficient adhesive on the tabs.

[0023] Please see Figure 2 and Figure 3 The conveying device 1 includes a roller mounting structure, a rotating shaft 11, a roller 12, and at least one positioning component.

[0024] The rotating shaft 11 is mounted on the idler roller mounting structure.

[0025] The idler roller mounting structure includes a first mounting plate 131, a second mounting plate 132, and a locking member 133. The first mounting plate 131 has mounting holes. The second mounting plate 132 is spaced apart from the first mounting plate 131 and located on one side of the mounting holes along their axial direction. The second mounting plate 132 has a mounting groove with one open end, the position of which corresponds to the position of the mounting holes. One end of the rotating shaft 11 is detachably inserted into the mounting hole, and the other end is installed in the mounting groove. The locking member 133 is connected to the rotating shaft 11 and detachably connected to the second mounting plate 132 to lock the rotating shaft 11 onto the second mounting plate 132.

[0026] The locking component 133 includes a insert 134, a first fastening screw 135, and a second fastening screw 136. The insert 134 has a mounting hole, and the end of the rotating shaft 11 furthest from the first mounting plate 131 passes through the mounting hole, allowing the rotating shaft 11 to move axially along the mounting hole. Figure 3 In the illustrated embodiment, the mounting hole is a threaded hole, and the rotating shaft 11 is threadedly connected to the mounting hole. This allows the threaded engagement position between the mounting hole and the rotating shaft 11 to be changed when the rotating shaft 11 is rotated, thereby adjusting the position of the idler roller 12 on the rotating shaft 11 in the axial direction. It should be noted that the rotating shaft 11 and the mounting hole can also be slidably connected, and the position of the idler roller 12 in the axial direction can be adjusted by pushing the rotating shaft 11 to move along its axial direction.

[0027] The second fastening screw 136 is disposed on the insert 134 and connected to the rotating shaft 11 to lock the rotating shaft 11 onto the insert 134. The end of the insert 134 away from the rotating shaft 11 is detachably connected to the second mounting plate 132 by the first fastening screw 135, thereby locking the rotating shaft 11 onto the second mounting plate 132.

[0028] The idler roller 12 is sleeved on the outer periphery of the rotating shaft 11 and is rotatable relative to the rotating shaft 11. The idler roller 12 includes a plurality of roller teeth 122 arranged circumferentially.

[0029] At least one positioning component includes a positioning block 140 sleeved on the rotating shaft 11 and spaced at the axial end of the idler roller 12, a first positioning member 141 disposed at the end of the idler roller 12, and a second positioning member 142 disposed on the positioning block 140. The first positioning member 141 and the second positioning member 142 are magnetically attracted to each other to achieve circumferential positioning of the idler roller 12.

[0030] The magnetic attraction between the first positioning element 141 and the second positioning element 142 ensures that when the idler roller 12 stops rotating, the first positioning element 141 corresponds exactly to the second positioning element 142, thereby avoiding the inertial rotation of the idler roller 12 and preventing rubbing or even scratching the tab rubber 92, thus ensuring the quality of the tab belt 91.

[0031] The positioning block 140 is fixedly connected to the rotating shaft 11. When the conveying device is conveying the tab belt 91, the rotating shaft 11 and the positioning block 140 are fixed, while the idler roller 12 rotates relative to the rotating shaft 11 to convey the tab belt 91.

[0032] See Figure 4 The positioning block 140 has a through mounting hole, the axis of which is parallel to the axis of the rotating shaft 11. Specifically, the positioning block 140 has a positioning tooth 144 corresponding to the roller tooth 122, the positioning tooth 144 has a mounting hole, and the second positioning member 142 is disposed in the mounting hole.

[0033] The roller has five teeth 122. Therefore, each positioning assembly has five first positioning elements 141, each positioning block 140 has five positioning teeth 144, and each positioning assembly has five second positioning elements 142. When the roller 12 rotates, it can rotate so that the roller teeth 122 correspond one-to-one with the positioning teeth 144, and each roller tooth 122 is directly opposite the corresponding positioning tooth 144.

[0034] In some embodiments, the positioning block 140 may not have positioning teeth 144. Its cross-section is circular, and its outer periphery extends outward to correspond to the roller teeth 122. The second positioning member 142 is directly disposed on the positioning block 140 at the location corresponding to the roller teeth 122.

[0035] At least one of the first positioning element 141 and the second positioning element 142 is a magnetic material. That is, both can be magnetic materials, or one can be a magnetic material and the other can be a metal material.

[0036] In this example, the first positioning element 141 is a magnetic material, and the second positioning element 142 is a metal material, with the magnetic material capable of attracting the metal material. In other embodiments, both the first positioning element 141 and the second positioning element 142 are magnetic materials. Alternatively, the first positioning element 141 is a metal material, and the second positioning element 142 is a magnetic material.

[0037] Magnetic materials refer to substances or materials that can generate magnetic fields. Metallic materials include iron, cobalt, nickel, and their alloys. Iron, cobalt, nickel, and their alloys are ferromagnetic materials, possessing significant magnetism and capable of being attracted by magnets.

[0038] Specifically, in this embodiment, the magnetic body can be a magnet, and the metal part can be made of iron. The magnet generates a magnetic field that attracts iron.

[0039] Please see Figure 5 and Figure 6 As shown, the adhesive feeding device for the tab adhesive 92 according to an embodiment of the present invention (hereinafter referred to as the adhesive feeding device) includes a horizontal support 21, a vertical support 22, a guide fork 23, an adhesive clamping assembly 24, a first pressing assembly 25, and two second pressing assemblies 26. The vertical support 22 is vertically connected to one end of the horizontal support 21, and an output channel 221 is provided on the vertical support 22.

[0040] The guide fork 23 is slidably mounted on the horizontal support 21. The guide fork 23 has two vertically spaced guide fork teeth 231, each with a guide groove 232 extending through both ends of the guide fork 23. The guide groove 232 is used to pass through the tab adhesive 92. The discharge end of the guide fork 23 can output the tab adhesive 92 to the next station via the output channel 221. A clamping assembly 24 is connected to the feed end of the guide fork 23 and is used to clamp the tab adhesive 92 onto the guide fork 23.

[0041] refer to Figure 3 As shown, the first pressing assembly 25 is mounted on the vertical support 22. The first pressing assembly 25 includes a first driving member 251 and two first pressing blocks 252. The two first pressing blocks 252 are located between the two guide forks 231. The first driving member 251 is used to drive the two first pressing blocks 252 away from each other so that parts of the two first pressing blocks 252 can respectively extend into the two guide grooves 232, or drive the two first pressing blocks 252 closer to each other so that the two first pressing blocks 252 respectively exit the two guide grooves 232.

[0042] Two second pressing assemblies 26 are mounted on the vertical support 22 and located on the upper and lower sides of the guide fork 23, respectively. Each second pressing assembly 26 includes a second driving member 261 and a second pressing block 262. The second pressing block 262 is arranged vertically corresponding to the first pressing block 252. The second driving member 261 is used to drive the second pressing block 262 to move closer to or away from the corresponding first pressing block 252, so as to clamp or release the tab rubber 92.

[0043] The adhesive feeding device of the present invention can drive the tab adhesive 92 to the next station through the reciprocating motion of the guide fork 23, and realize the segmented output of the tab adhesive 92. The adhesive clamping assembly 24 can clamp the tab adhesive 92 onto the guide fork 23, so that the tab adhesive 92 can be conveyed forward together with the guide fork 23. The first pressing assembly 25 and two second pressing assemblies 26 can clamp the tab adhesive 92 when it is delivered to the position, so that the tab adhesive 92 is fixed in the current position. Then the adhesive clamping assembly 24 can release the tab adhesive 92, the guide fork 23 can move backward and reset, and clamp the next segment of tab adhesive 92 through the adhesive clamping assembly 24, and then drive the tab adhesive 92 forward.

[0044] Furthermore, during the forward conveying of the tab adhesive 92 by the guide fork 23, the two first pressure blocks 252 of the first pressure assembly 25 can be positioned close to each other, without each first pressure block 252 extending into the guide groove 232. This ensures that the tab adhesive 92 in the guide groove 232 is smoothly output forward, avoiding the risk of material blockage caused by the first pressure blocks 252 rubbing against the tab adhesive 92. Additionally, the second pressure block 262 of the second pressure assembly 26 can be positioned away from the corresponding first pressure block 252 to avoid friction between the second pressure block 262 and the tab adhesive 92, thus ensuring that the tab adhesive 92 in the guide groove 232 can be smoothly output forward.

[0045] Therefore, the glue feeding device of this embodiment can not only realize the segmented and continuous output of the tab glue 92 to the next station, but also ensure that the tab glue 92 in the guide trough 232 can be output smoothly, reducing the risk of material blockage during the output process of the tab glue 92 and effectively improving the production efficiency of the tab glue 92.

[0046] The specific embodiments of the glue feeding device of the present invention will be described in detail below with reference to the accompanying drawings.

[0047] For ease of understanding and description, in this invention, the conveying direction of the tab adhesive 92 is defined as the horizontal front-to-back direction, the vertical direction perpendicular to the front-to-back direction is the up-down direction, and the horizontal direction perpendicular to the front-to-back direction is the left-to-right direction.

[0048] The power component 28 includes a lead screw 281 and a motor 282. The lead screw 281 is threadedly connected to the sliding seat 271. The motor 282 is connected to one end of the lead screw 281 and is used to drive the lead screw 281 to rotate so that the sliding seat 271 can move along the length direction of the linear slide rail 211.

[0049] See Figure 5As shown, the clamping assembly 24 is connected to the feed end of the guide fork 23. Specifically, the clamping assembly 24 can be fixedly mounted on the mounting bracket 27. When the tab adhesive 92 passes through the guide groove 232, the clamping assembly 24 can clamp the tab adhesive 92 into the corresponding guide groove 232 on the guide fork 23. Thus, when the guide fork 23 moves forward, the tab adhesive 92 can be conveyed forward with the guide fork 23.

[0050] For example, the clamping assembly 24 may include two third driving members 241 and two third pressing blocks 242, with the two third pressing blocks 242 respectively arranged corresponding to the two guide grooves 232. The two third driving members 241 are used to drive the two third pressing blocks 242 to move up and down, so that the third pressing blocks 242 can extend into the guide grooves 232 and press the tab adhesive 92 onto the guide fork 23. The third driving members 241 may be electric push rods or linear cylinders.

[0051] In this embodiment, when the tab adhesive 92 is inserted into the guide groove 232, the upper third pressure block 242 can move downward under the drive of the corresponding third drive member 241 to clamp the tab adhesive 92 onto the guide fork 23. The lower third pressure block 242 can move upward under the drive of the corresponding third drive member 241 to clamp the tab adhesive 92 onto the guide fork 23. Thus, when the guide fork 23 moves forward, the two tab adhesives 92 can be conveyed forward with the guide fork 23. It can be understood that after the guide fork 23 has conveyed the tab adhesive 92 into place, the guide fork 23 stops moving forward. The two third pressure blocks 242 can release the two tab adhesives 92 respectively, so that the front part of the tab adhesive 92 can be kept in the current position. Then the guide fork 23 and the adhesive clamping assembly 24 can synchronously reset backward to clamp and convey the next part of the tab adhesive 92.

[0052] See Figure 6 and Figure 7 The first pressing assembly 25 is mounted on the vertical support 22. The first pressing assembly 25 includes a first driving member 251 and two first pressing blocks 252, which are located between two guide forks 231. The first driving member 251 can drive the two first pressing blocks 252 away from each other so that parts of the two first pressing blocks 252 can respectively extend into the two guide grooves 232, so that each first pressing block 252 can cooperate with the corresponding second pressing block 262 to press and fix the tab adhesive 92.

[0053] Alternatively, the first driving member 251 can drive the two first pressing blocks 252 to move closer to each other so that the two first pressing blocks 252 exit the two guide grooves 232 respectively, so that each first pressing block 252 can cooperate with the corresponding second pressing block 262 to loosen the tab adhesive 92.

[0054] Optionally, the first driving component 251 is a parallel pneumatic gripper, and the two first pressure blocks 252 are respectively fixed on the two grippers of the parallel pneumatic gripper. It can be understood that the structure and principle of the parallel pneumatic gripper can refer to the parallel pneumatic grippers in related technologies, as long as it can achieve the purpose of making the two first pressure blocks 252 move away from or close to each other.

[0055] Alternatively, in other embodiments, the first drive member 251 may also be other forms of clamping drive member, such as a linkage drive mechanism. The goal is simply to achieve the purpose of moving the two first pressure blocks 252 away from or towards each other.

[0056] like Figure 7 As shown, in one embodiment, a first protrusion 253 is provided on the opposing surfaces of the first pressing block 252 and the second pressing block 262. The width of the first protrusion 253 matches the guide groove 232 so that it can extend into the guide groove 232. The first protrusion 253 may be a strip-shaped protrusion or a protruding post, which is used to abut against the corresponding second pressing block 262 to achieve the purpose of pressing and fixing the tab adhesive 92.

[0057] See Figure 5 and Figure 7 As shown, two second pressing assemblies 26 are mounted on the vertical support 22 and located on the upper and lower sides of the guide fork 23, respectively. Each second pressing assembly 26 includes a second driving member 261 and a second pressing block 262, which are arranged vertically corresponding to the first pressing block 252. The second driving member 261 drives the second pressing block 262 to move closer to or away from the corresponding first pressing block 252, thereby clamping or releasing the tab rubber 92. Optionally, the second driving member 261 is a linear cylinder or an electric push rod.

[0058] like Figure 7 As shown, in one embodiment, the second pressing block 262 has a second protrusion 263 on its surface opposite to the first pressing block 252. The width of the second protrusion 263 matches the guide groove 232 so that it can extend into the guide groove 232. The second protrusion 263 can be a strip-shaped protrusion or a protruding post, which is used to abut against the corresponding first pressing block 252 to achieve the purpose of pressing and fixing the tab adhesive 92.

[0059] In this invention, after the guide fork 23 delivers the tab adhesive 92 into position, the guide fork 23 stops moving forward. At this time, the first drive member 251 can drive the two first pressure blocks 252 to move away from each other, so that the two first protrusions 253 can respectively extend into the two guide grooves 232. Simultaneously, the second drive member 261 located on the upper side of the guide fork 23 can drive the second pressure block 262 to move downward to abut against the upper first pressure block 252 to clamp the tab adhesive 92. The second drive member 261 located on the lower side of the guide fork 23 can drive the second pressure block 262 to move upward to abut against the lower first pressure block 252 to clamp the tab adhesive 92. Thus, the first pressure assembly 25 and the two second pressure assemblies 26 can clamp and fix the two tab adhesives 92, keeping the tab adhesives 92 in their current position for easy processing in the next step. Then, the clamping assembly 24 releases, and the power component 28 drives the mounting bracket 27 to move backward, achieving synchronous rearward reset of the guide fork 23 and the clamping assembly 24. Afterward, the clamping assembly 24 can clamp the next section of adhesive strip onto the guide fork 23, allowing the guide fork 23 to convey the next section of adhesive strip forward again. Repeating this process enables continuous segmented output of the tab adhesive 92.

[0060] Furthermore, each time the guide fork 23 moves forward to deliver adhesive, the first drive member 251 can drive the two first pressure blocks 252 to remain in a close-to-each-other position, so that the two first protrusions 253 respectively exit the two guide grooves 232, avoiding the risk of material blockage caused by the first protrusions 253 rubbing against the tab adhesive 92. Similarly, the second drive member 261 can drive the second pressure block 262 away from the corresponding first pressure block 252, avoiding the risk of material blockage caused by the second protrusions 263 rubbing against the tab adhesive 92. This ensures that the tab adhesive 92 in the guide groove 232 is smoothly output forward, improving the smoothness and continuity of the tab adhesive 92 delivery.

[0061] See Figure 5 In one embodiment, the adhesive feeding device for the tab adhesive 92 further includes a clamping roller assembly 29, which is disposed on the sliding seat 271 and located behind the feed end of the guide fork 23. The clamping roller assembly 29 includes two clamping rollers 291 arranged in pairs, the distance between the two clamping rollers 291 being adjustable, and the two clamping rollers 291 being used to clamp the tab adhesive 92.

[0062] In the glue feeding device of the present invention, firstly, two tab glues 92 are passed between two clamping rollers 291 and respectively inserted into two guide grooves 232, with the two clamping rollers 291 clamping the two tab glues 92. Then, the clamping assembly 24 is used to clamp the two tab glues 92 into the two guide grooves 232 of the guide fork 23. At the same time, the two first pressing blocks 252 of the first pressing assembly 25 are in a position close to each other to avoid the tab glues 92 in the guide grooves 232; the second pressing block 262 of the second pressing assembly 26 is in a position away from the corresponding first pressing block 252 to avoid the tab glues 92 in the guide grooves 232.

[0063] Then, the power component 28 drives the sliding seat 271 to move forward, so that the guide fork 23 can drive the two tab rubbers 92 to be output forward synchronously to the next station. When the guide fork 23 has moved forward to its position, the guide fork 23 stops moving forward. At this time, the first drive component 251 can drive the two first pressure blocks 252 to move away from each other so that the two first protrusions 253 extend into the two guide grooves 232 respectively. At the same time, the second drive component 261 drives the second pressure block 262 to move closer to the corresponding first pressure block 252, so that the first pressure block 252 and the second pressure block 262 cooperate to clamp and fix the tab rubbers 92 in the two guide grooves 232 respectively.

[0064] Subsequently, the clamping assembly 24 and the clamping roller group 29 release the tab rubber 92, and the power component 28 drives the sliding seat 271 to move backward, causing the guide fork 23 and the clamping roller group 29 to move backward and reset synchronously to clamp and fix the next section of tab rubber 92. Repeating the above process can achieve continuous and synchronous output of the two tab rubbers 92.

[0065] The feeding device for the tab adhesive 92 in this embodiment of the invention can convey the tab adhesive 92 to the next station and achieve segmented output of the tab adhesive 92 through the reciprocating motion of the guide fork. The tab adhesive 92 can be clamped onto the guide fork by the clamping assembly, allowing it to be conveyed forward along with the guide fork. The first pressing assembly and two second pressing assemblies can clamp the tab adhesive 92 when it reaches its position, keeping it fixed in that position. Then, the clamping assembly can release the tab adhesive 92, allowing the guide fork to move backward and reset, clamping the next segment of tab adhesive 92 again, and then conveying the tab adhesive 92 forward.

[0066] Furthermore, during the forward conveying of the tab adhesive 92 by the guide fork, the two first pressure blocks of the first pressing assembly can be positioned close to each other, with neither first pressure block extending into the guide groove. This ensures that the tab adhesive 92 in the guide groove is smoothly output forward, avoiding the risk of material blockage caused by friction between the first pressure blocks and the tab adhesive 92. Additionally, the second pressure block of the second pressing assembly can be positioned away from the corresponding first pressure block to avoid friction with the tab adhesive 92 and subsequent material blockage, thus ensuring that the tab adhesive 92 in the guide groove can be smoothly output forward.

[0067] Please see Figure 8 and Figure 9 The cutting machine 3 may include a mounting bracket 310, a moving blade module 320, and a fixed blade 330.

[0068] The mounting bracket 310 extends vertically to facilitate the installation of the moving tool module 320 and the fixed tool 330. The moving tool module 320 may include a moving tool assembly 342 and a moving tool drive assembly 322. The moving tool drive assembly 322 is mounted on the mounting bracket 310, and the moving tool assembly 342 is detachably connected to the output end of the moving tool drive assembly 322, so that the moving tool drive assembly 322 can drive the moving tool assembly 342 to move relative to the mounting bracket 310.

[0069] In this embodiment, the fixed blade 330 is detachably connected to the mounting bracket 310, and the fixed blade 330 and the moving blade assembly 342 are located on the same side of the mounting bracket 310. The fixed blade 330 is located between the moving blade assembly 342 and the mounting bracket 310, so that after the moving blade assembly 342 is detached from the moving blade drive assembly 322, it can avoid the fixed blade 330, so that the fixed blade 330 can be detached from the mounting bracket 310.

[0070] Meanwhile, the fixed blade 330 is provided with a cutting part 331, which is located on the side of the fixed blade 330 facing the moving blade assembly 342 and is arranged corresponding to the moving blade assembly 342. When the moving blade assembly 342 moves relative to the mounting bracket 310 under the drive of the moving blade drive assembly 322, the moving blade assembly 342 and the cutting part 331 move relative to each other and can cut the tab adhesive 92 so that the length of the tab adhesive 92 meets the requirements of the tab.

[0071] It should be noted that since the fixed blade 330 is detachably connected to the mounting bracket 310, it is convenient to install the fixed blade 330 onto the mounting bracket 310 or to remove the fixed blade 330 from the mounting bracket 310, so as to repair or replace the fixed blade 330. This avoids the defects in the existing structure, such as the need to remove the moving blade from the mounting bracket before repairing or replacing the fixed blade.

[0072] See Figure 1 and Figure 2The cutting machine may also include a connecting plate 311, a guide rail, a base plate 313, and an adjusting component 314. The base plate 313 is mounted on a support surface or base. The connecting plate 311 is used to connect the mounting bracket 310, and the connecting plate 311 is connected to the base plate 313 via the guide rail, allowing the connecting plate 311 to move relative to the base plate 313. Specifically, the base plate 313 is provided with a guide groove adapted to the guide rail. The guide rail 312 is connected to the connecting plate 311 and connected to the guide groove, allowing the guide rail to move along the guide groove.

[0073] The adjusting member 314 is connected between the connecting plate 311 and the base plate 313 to adjust the relative position of the connecting plate 311 and the base plate 313. That is, by rotating the adjusting member 314, the connecting plate 311 can be moved relative to the base plate 313, thereby adjusting the position of the connecting plate 311 and the mounting bracket 310 so that the working position of the cutting machine meets the actual needs.

[0074] Figure 10 yes Figure 8 A schematic diagram of the fixed blade 330 of the cutting machine.

[0075] The fixed blade 330 may have a through hole 332. The through hole 332 is used to pass through the tab adhesive 92 to be cut, and the opening of the through hole 332 facing the moving blade module 320 forms a cutting part 331, so that when the cutting part 331 and the moving blade assembly 342 move relative to each other, the cutting part 331 and the moving blade assembly 342 can cut the tab adhesive 92 simultaneously.

[0076] It should be noted that a clearance section 334 is provided inside the through hole 332. The clearance section 334 is used to avoid the glue feeding mechanism, so that the glue feeding mechanism can transport the tab glue 92 to the moving knife assembly 342.

[0077] In this embodiment, the fixing blade 330 may be provided with two through holes 332, and the two through holes 332 are spaced apart, so that the two through holes 332 correspond to the opposite two sides of the tab. At the same time, two moving blade modules 320 are provided, and each moving blade module 320 corresponds to one through hole 332. That is, the two tab adhesives 92 to be cut pass through the through holes 332 respectively, and after being cut by the moving blade assembly 342 and the cutting part 331 of the moving blade module 320, the tab adhesives 92 are attached to the opposite two sides of the tab strip 91 at the same position.

[0078] In summary, the cutting machine includes a mounting frame 310, a moving blade module 320, and a fixed blade 330. The moving blade module 320 includes a moving blade assembly 342 and a moving blade drive assembly 322. The moving blade drive assembly 322 is connected to the mounting frame 310, and the moving blade assembly 342 is detachably connected to the output end of the moving blade drive assembly 322, enabling the moving blade drive assembly 322 to move relative to the mounting frame 310. The fixed blade 330 is detachably connected to the mounting frame 310 and is located on the same side of the mounting frame 310 as the moving blade assembly 342, between the moving blade assembly 342 and the mounting frame 310. The fixed blade 330 is provided with a cutting section 331, which is positioned corresponding to the moving blade assembly 342. When the moving blade assembly 342 moves relative to the mounting frame 310, the moving blade assembly 342 and the cutting section 331 move relative to each other, enabling the cutting of the tab adhesive 92. Since the moving blade assembly 342 is detachably connected to the moving blade drive assembly 322 and the fixed blade 330 is detachably connected to the mounting bracket 310, after the moving blade assembly 342 is removed from the moving blade drive assembly 322, interference between the moving blade assembly 342 and the fixed blade 330 can be avoided, allowing the fixed blade 330 to be directly removed from the mounting bracket 310, thus facilitating the operator's maintenance or replacement of the fixed blade 330.

[0079] Please see Figure 11 The electrode punching device 4 includes a frame 411, a first adjustment module 412, a punch module 413, and a second adjustment module 414.

[0080] The frame 411 includes a support frame 4111 and a support plate 4112. The front and rear sides of the support plate 4112 provide support surfaces for mounting various equipment. The support plate 4112 is placed vertically. Both support surfaces are vertical. These two support surfaces can be a first support surface 4113 and a second support surface 4114.

[0081] Furthermore, a feed port 4115 is provided on the support plate 4112, which penetrates both support surfaces of the support plate 4112. The electrode lug structure 90 passes through the feed port 4115. Guide tables 430 and conveying rollers 20 are respectively provided on both sides of the feed port 4115.

[0082] For ease of explanation, we define the direction perpendicular to the support surface as the Y-axis, the vertical direction within the support surface as the Z-axis, and the horizontal direction within the support surface as the X-axis.

[0083] Please see Figure 12A first adjustment module 412 is mounted on a frame 411. The first adjustment module 412 includes a first drive device 4121 and a first track 4122, which extends along a first direction. Specifically, in this embodiment, the first drive device 4121 can be a first servo motor. The first track 4122 is a first lead screw. The first servo motor is driven by the first lead screw, causing it to rotate. The first drive device 4121 and the first track 4122 are mounted on the first support surface 4113 of the support plate 4112. The first track 4122 extends along the X-axis. Furthermore, a track groove 4116 is provided on the support plate 4112. The track groove 4116 penetrates the first support surface 4113 and the second support surface 4114 of the support plate 4112. The track groove 4116 is parallel to the first track 4122 and also extends along the X-axis. In other embodiments, the first drive device 4121 can also be a cylinder or other drive device.

[0084] Please also refer to Figure 13 The first adjustment module 412 also includes an adapter plate 4123. The adapter plate 4123 is Z-shaped. The adapter plate 4123 includes a first segment 4124, a second segment 4125, and a third segment 4126. The first segment 4124 passes through the track groove 4116 and is connected to the first lead screw. The third segment 4126 of the adapter plate 4123 is arranged parallel to the second support surface 4114 and perpendicular to the second support surface 4114. When the first lead screw rotates, it drives the adapter plate 4123 to move along the first lead screw. Furthermore, two parallel slide rails 4117 are provided on the second support surface 4114. The slide rails 4117 extend along the X-axis direction.

[0085] The second segment 4125 of the adapter plate 4123 is slidably connected to the slide rail 4117. The slide rail 4117 can provide guidance and stability for the movement of the adapter plate 4123, and the connection between the adapter plate 4123 and the support plate 4112 can enable the third segment 4126 of the adapter plate 4123 to have a high load-bearing capacity.

[0086] The tab punching device 400 also includes a punching table 415 and a support table 416. Both the punching table 415 and the support table 416 are located near the second support surface 4114 of the support plate 4112. The punching table 415 is used to hold the material to be processed. The support table 416 is used to fix and support the punch module 413.

[0087] The punching table 415 is platform-shaped. The punching table 415 has high strength to support the punching pressure. The punching table 415 is fixedly mounted on the third segment 4126 of the adapter plate 4123. Therefore, the punching table 415 can move along the two slide rails 4117 with the adapter plate 4123.

[0088] The support platform 416 can be fixedly mounted on the punching table 415. Specifically, one end of the support platform 416 is fixedly mounted on the punching table 415. The support platform 416, the punching table 415, and the adapter plate 4123 move back and forth together along the X-axis.

[0089] A boss 4161 is provided at one end of the support platform 416 that contacts the punching table 415. This boss 4161 raises the height of the support platform 416, creating a gap between the other end of the support platform 416 and the punching table 415. This gap forms a punching channel 4162 for punching the material to be processed. The punching channel 4162 communicates with the feed port 4115 on the support plate 4112, allowing the material to be processed to pass through the punching channel 4162, be punched, and then be conveyed out through the feed port 4115.

[0090] The punch module 413 is used to punch the material to be processed. The punch module 413 is fixedly supported on the support table 416. The punch module 413 can reciprocate along the X-axis direction with the support table 416.

[0091] Please see Figure 14 The punch module 413 includes a drive motor 4131, a transmission shaft 4132, a cam 4133, and a tool holder 4134. The drive motor 4131 is driven and connected to the transmission shaft 4132. The drive motor 4131 can be fixedly connected to the transmission shaft 4132 through connecting devices such as a reducer (not shown in the figure), a coupling (not shown in the figure), and a bearing (not shown in the figure). One end of the transmission shaft 4132 is the drive end, and the drive end is provided with a cam 4133. The transmission shaft 4132 drives the cam 4133 to rotate, and the cam 4133 is eccentrically set with respect to the transmission shaft 4132. The tool holder 4134 is fixedly connected to the cam 4133.

[0092] Please see Figure 15 The tool holder 4134 is used to mount the punch 4135. The drive shaft 4132 drives the cam 4133 to rotate, thereby driving the tool holder 4134 to move up and down, causing the punch 4135 on the tool holder 4134 to move towards or away from the material to be processed, and to punch the material. Specifically, in this embodiment, the drive motor 4131 can be a servo motor. The servo motor drives the drive shaft 4132 to rotate one revolution, which drives the cam 4133 to rotate. Since the cam 4133 and the drive shaft 4132 are eccentrically set, the tool holder 4134 set on the cam 4133 achieves one up and down movement.

[0093] Specifically, in this embodiment, the drive motor 4131 can be a servo motor, which can achieve a faster and more uniform processing rhythm, which is beneficial to improving processing efficiency and ensuring the stability and controllability of punching operation.

[0094] The tool holder 4134 has a first guide groove 4136. The support platform 416 has a first guide post 4137. The first guide post 4137 is fixedly attached to the support platform 416 by a threaded connection.

[0095] The first guide post 4137 is slidably inserted into the first guide groove 4136. There can be multiple first guide posts 4137, which are symmetrically distributed around the tool holder 4134. The first guide posts 4137 guide the vertical movement of the tool holder 4134.

[0096] Please see Figure 15 The free end of the punch 4135 is also equipped with a pressure plate 4138. The pressure plate 4138 is elastically connected to the cutter holder 4134 via two second guide posts 4139. Specifically, a spring or elastic post can be provided between one end of the second guide post 4139 and the cutter holder 4134 to achieve an elastic connection. The other end of the second guide post 4139 is fixedly connected to the pressure plate 4138 by means of threaded connection, welding, etc. That is, when the cutter holder 4134 moves up and down, it drives the pressure plate 4138 to move up and down together. The pressure plate 4138 is used to hold the surface of the material to be processed, preventing the material from shifting during the punching process and causing processing deviation.

[0097] Please see Figure 16 Specifically, the support platform 416 is provided with a first through hole 4163 for the punch 4135 to pass through. The shape of the first through hole 4163 is adapted to the cross-section of the punch 4135. Thus, the punch 4135 can pass through the first through hole 4163 of the support platform 416.

[0098] The support platform 416 has a second guide groove 4164, and the second guide post 4139 is slidably disposed within the second guide groove 4164. The second guide post 4139 can guide the punching movement to ensure the accuracy of the punching position.

[0099] Furthermore, the pressure plate 4138 has a second through hole 1381 for the punch 4135 to pass through. The shape of the second through hole 1381 is adapted to the cross-section of the punch 4135. When the tool holder 4134 descends, it drives the pressure plate 4138 and the free end of the punch 4135 into the punching channel 4162 and down to the surface of the material to be processed. The pressure plate 4138 presses against the surface of the material to be processed, maintaining stable pressure. The punch 4135 continues to pass downward through the pressure plate 4138, punching the material to be processed on the punching table 415.

[0100] Furthermore, the punching table 415 is provided with a punching hole 4151 that matches the cross-section of the punch 4135. During the downward punching process, after the punch 4135 contacts the material to be processed, it continues to punch and penetrates into the punching hole 4151 on the punching table 415, thereby forming a punching shape on the material to be processed that matches the cross-sectional shape of the punch 4135. Specifically, in this embodiment, the shape of the punch 4135 includes two oppositely arranged arc surfaces (not shown in the figure). Thus, the punch 4135 forms a chamfer structure on the material.

[0101] After the punch 4135 completes the punching of the material, the cutter holder 4134 is lifted, and the pressure plate 4138, punch 4135, and material to be processed are separated, ready for the next punching operation. Specifically, in this embodiment, the support table 416 has a relief groove 4165 on one side facing the punching table 415. The relief groove 4165 is used to accommodate the pressure plate 4138. The relief groove 4165 can accommodate the pressure plate 4138, preventing the pressure plate 4138 from protruding from the side of the support table 416 and preventing the pressure plate 4138 from interfering with the material during the transmission process.

[0102] When different material design requirements result in different widths of the tabs 91 and different spacing between them, meaning the punching position of the adhesive layer 92 changes in the X-axis direction, the first adjustment module 412 can drive the punch 4135 module to adjust along the X-axis direction, thereby adjusting the punching position of the punch 4135.

[0103] Please see Figure 14 The second adjustment module 414 is used to drive the frame 411 to move as a whole, thereby adjusting the position of the frame 411. The second adjustment module 414 includes a second drive device 4141 and a second track 4142. The second track 4142 extends along a second direction, wherein the first direction intersects with the second direction. Specifically, in this embodiment, the second drive device 4141 can be a second servo motor. The second track 4142 is a second lead screw. The second servo motor is driven by the second lead screw, and the second servo motor drives the second lead screw to rotate. The second drive device 4141 and the second track 4142 are located below the support plate 4112. The second track 4142 is along the Y-axis direction. The first direction is perpendicular to the second direction. In other embodiments, the second drive device 4141 can also be a cylinder or other drive device.

[0104] The frame 411 is movably mounted on the second track 4142, and the second drive device 4141 drives the frame 411 to move along the second track 4142. During the punching process, the conveyor roller 20 conveys the material to be processed along the Y-axis. When the conveying position deviates, the second drive device 4141 can adjust the position of the frame 411 in the Y-axis direction, which can realize the calibration of the punching position of the punch 4135 on the material to be processed, and improve the accuracy of the punching operation.

[0105] Please see Figure 17 The tab-cutting device 400 also includes a sensor 417. The sensor 417 is located above the punch module 413. The sensor 417 measures the distance between the material to be processed and the punch 4135 along the Y-axis. This distance information can be the distance between one end face of the punch 4135 and the edge of the material to be processed along the Y-axis, i.e., the length of the projection of the punch onto the material. The sensor 417 is electrically connected to a second drive device 4141. When this distance information is greater than a threshold, the second drive device 4141 moves the frame 411. The threshold can be the distance between a preset cutting position and the punch 4135. It is understood that the sensor 417 can be a vision sensor, a distance sensor, etc.

[0106] Specifically, in this embodiment, sensor 417 can be a laser sensor, which includes a transmitting sensor 4171 and a receiving sensor 4172. The transmitting sensor 4171 and the receiving sensor 4172 are arranged vertically opposite each other. The transmitting sensor 4171 is used to emit laser signals, and the receiving sensor 4172 is used to receive laser signals. Based on the laser signal reception, the aforementioned distance information is calculated.

[0107] When sensor 417 measures a large deviation between the preset cutting position of the material to be processed and the punch 4135, it may result in the punch 4135 failing to cut the material, or the length of the projection of the punch on the material being processed being too large or too small, causing the chamfer formed by the punch 4135 on the material to be processed to have a smaller or larger size along the Y-axis. Sensor 417 detects the distance between the material to be processed and the punch 4135 and sends a control signal to the second drive device 4141. The preset cutting position allows adjustment of the size of the chamfer formed by the punch on the adhesive layer 92. For example, if the preset chamfer size in the Y-axis direction is large, the position of the punch 4135 in the Y-axis direction needs to be adjusted to increase the projected area of ​​the punch 4135 on the material to be processed.

[0108] Please see Figure 17Specifically, the tab punching device 400 also includes a controller 418. The controller 418 can be electrically connected to the sensor 417 and the second drive device 4141. The controller 418 receives the distance information and determines the moving displacement of the frame 411 based on the distance information and preset position information. When the second drive device 4141 is a servo motor, the controller 418 can also calculate the number of rotations of the servo motor and control the servo motor to work, so that the punching position of the punch 4135 accurately reaches the preset punching position.

[0109] Furthermore, the controller 418 can also be electrically connected to the first drive device 4121. The controller 418 can receive the size information of the material to be processed, and control the movement of the first drive device 4121 through the size information, adjusting the cutting position of the cutter 4135 in the X-axis direction, which facilitates automated manufacturing.

[0110] Therefore, in the aforementioned tab punching device 400, when processing different product sizes, the punch module 413 can be moved along the X-axis and Y-axis directions by adjusting the first drive device 4121 of the first adjustment module 412 and the second drive device 4141 of the second adjustment module 414, thereby adjusting the processing position of the punch 4135 of the punch module 413 along the X-axis and Y-axis directions. Thus, the position of the punch module 413 can be adjusted in both the X-axis and Y-axis dimensions, allowing the tab punching device 400 to adapt to the punching position requirements of various product sizes and widths without the need to manufacture multiple different types of molds, saving equipment costs; it also eliminates the need for multiple replacements of components such as the punch module 413, avoiding complex disassembly and assembly work, and significantly reducing working time.

[0111] In the tab punching device 400 of this embodiment, the adhesive layer 92 is detected by the sensor 417, and the second adjustment module 414 is controlled to make fine adjustments along the Y direction to adjust the position and size of the punching chamfer. This can achieve precise control of the punching position and size, thereby improving the product yield.

[0112] The laser marking device 5 of this application is used to laser mark strip-shaped objects. For ease of description, strip-shaped items will be referred to as marking strips in the following text.

[0113] See Figure 18 , Figure 19 The laser marking device 500 includes a housing 510 and a laser generator 520.

[0114] The housing 510 has through holes 511 on opposite sides. The tape to be labeled can enter the housing 510 through one through hole 511 and move to the outside of the housing 510 through another through hole 511.

[0115] The laser generator 520 is used to mark the tape to be marked. Specifically, the top of the housing 510 has an opening 512. The laser generator 520 includes a main body 521 and an emitting part 522. The end of the main body 521 is connected to the emitting part 522. The emitting part 522 is capable of emitting laser light. The emitting part 522 is arranged correspondingly to the opening 512 on the housing 510 so that the laser light emitted by the emitting part 522 can enter the interior of the housing 510 and mark the tape to be marked inside the housing 510.

[0116] Multiple laser generators 520 can be provided, which can simultaneously perform laser marking on multiple strips to be marked, or simultaneously perform laser marking on different areas of the same strip to be marked, effectively improving marking efficiency.

[0117] This embodiment uses two laser generators 520, each capable of laser marking different strips to be marked, as an example. When multiple strips to be marked are threaded through the housing 510, these strips are typically spaced apart. Therefore, the laser generators 520 can be arranged adjacently or spaced apart along the direction of travel of the strips. Furthermore, along the direction perpendicular to the direction of travel of the strips, the laser generators 520 are staggered to correspond to the multiple strips to be marked, thereby achieving laser marking of the multiple strips.

[0118] The laser marking device 500 includes a support platform 530. The support platform 530 is located outside the housing 510. The support platform 530 has a support surface 5311. The bottom surface of the main body 521 of the laser generator 520 is supported by the support surface 5311. The support surface 5311 can support all or most of the bottom surface of the main body 521. Compared to a cantilevered laser generator 520, this application, by setting up the support platform 530, forms a stable support for the laser generator 520, effectively reducing the impact of vibration on the laser generator 520, thereby improving the stability of the marking operation and effectively improving the marking yield of the laser marking device 500 on the marking tape. Furthermore, the laser marking device 500 of this application is suitable for marking small-sized products with high precision requirements.

[0119] Furthermore, the center of gravity of the laser generator 520 is located on the support platform 530, which greatly improves the installation stability of the laser generator 520 and reduces the impact of vibration on the laser generator 520 compared to the cantilever installation structure.

[0120] The support platform 530 includes a support plate 531 and a mounting component 532. The support plate 531 is located on the top of the housing 510. The support surface 5311 is the side of the support plate 531 facing away from the housing 510. The support plate 531 has mounting holes 5312. The mounting component 532 can pass through the mounting holes 5312 and connect to the body 521 of the laser generator 520, thereby fixing the laser generator 520 to the support plate 531.

[0121] Multiple mounting members 532 are provided to ensure a stable connection between the laser emitter and the support plate 531. For example, the outer contour of the main body 521 of the laser generator 520 is approximately rectangular. Four mounting members 532 are provided, each corresponding to one of the four corners of the main body 521.

[0122] Mounting hole 5312 extends away from housing 510. Therefore, the operator can adjust the horizontal position of laser generator 520 according to the position of the strip to be marked, so that laser generator 520 can move horizontally toward or away from housing 510, so that the laser emitted by laser generator 520 can accurately mark on the strip to be marked.

[0123] The laser marking device 500 includes a shock absorber 533, which is disposed between the laser generator 520 and the support surface 5311 of the support plate 531 to isolate and reduce vibration. Exemplarily, the shock absorber 533 can be disposed on the mounting member 532, with one end of the shock absorber 533 in contact with the bottom surface of the main body 521 of the laser generator 520, and the other end in contact with the support surface 5311 of the support plate 531. The shock absorber 533 can be a shock-absorbing adhesive, etc.

[0124] See Figure 20 , Figure 21 The tab detection device 6 includes a frame 1, a mounting base 2, an edge-following sensing mechanism 3, a probe mechanism 4, and a moving mechanism 5. The mounting base 2 is movably mounted on the side wall of the frame 1 and can move longitudinally relative to the frame 1. The edge-following sensing mechanism 3 is mounted on the mounting base 2 and is used to detect the tab adhesive 92 signal at the upstream station 220 on the tab 200. The probe mechanism 4 is mounted on the mounting base 2 and is located longitudinally downstream of the edge-following sensing mechanism 3. The probe mechanism 4 is used to detect whether there is tab adhesive 92 at the downstream stations 230 on both sides of the horizontally arranged tab 200. The downstream stations 230 and upstream stations 220 correspond to two adjacent tapes 200. The adjusting mechanism 5 is electrically connected to the mounting base 2 and the edge-following sensing mechanism 3, respectively, to drive the mounting base 2 to move longitudinally relative to the frame 1 according to the signal from the edge-following sensing mechanism 3, so that the edge-following sensing mechanism 3 can move within the range of the upstream station 220 to detect the tape signal.

[0125] In this application, since the edge-tracking sensing mechanism 3 and the probe mechanism 4 are arranged upstream and downstream, the edge-tracking sensing mechanism 3 is used to detect the tape signal at the upstream station of two adjacent stations on the tab 200. After the edge-tracking sensing mechanism 3 completes its detection, the probe mechanism 4 is used to detect whether there is tab adhesive 92 at the downstream station of two adjacent stations on the upper and lower sides of the tab 200. During the above detection process, the moving mechanism 5 can drive the mounting base 2 to move longitudinally relative to the frame 1 according to the signal when the edge-tracking sensing mechanism 3 is working, so that the edge-tracking sensing mechanism 3 can move within the range of the upstream station 220 to detect the tape signal of the upstream station 220 on the tab 200. That is, the edge-tracking sensing mechanism 3 can automatically move to find adhesive, so that the edge-tracking sensing mechanism 3 can smoothly perform the tab adhesive 92 detection work, and automatically adapt to the situation where the tab adhesive 92 deviates from the preset position during the production process, without the need for manual monitoring of the detection situation at all times, which can reduce the workload of manual labor and help to realize the automated detection of insufficient adhesive on the tab 200.

[0126] It should be noted that the above-mentioned longitudinal direction refers to the length direction of the horizontally placed electrode 200 (electrode band 91), and the transverse direction refers to the width direction of the horizontally placed electrode 200 (electrode band 91), and the same applies below.

[0127] In this embodiment, the tape signal includes a glue presence signal and a glue shortage signal. The glue presence signal is the lateral spacing D1 between two adjacent glue blocks 93 (referring to two glue blocks 93 corresponding to adjacent tabs 91) at the same workstation. The glue shortage signal is the lateral spacing D2 between a glue block 93 and a tab 91 at the same workstation, or the lateral spacing D3 between two adjacent tabs 91.

[0128] Figure 5 This is a schematic diagram of the detection principle of the edge-tracking sensing mechanism 3 in this embodiment.

[0129] refer to Figure 5 For example, the edge-tracking sensing mechanism 3 can be a through-beam sensor. In practical applications, preset interval distances D1, D2, and D3 are set within the edge-tracking sensing mechanism, and the specific values ​​of D1, D2, and D3 are set according to the actual situation. Among them, part of the signal emitted by the upper sensor 31 is blocked by the adhesive block 93 or the tab 91, and part of it is transmitted through the gap between two adjacent adhesive blocks 93, between the adhesive block 93 and the tab 91, or between two adjacent tabs 91, and is received by the lower sensor 32. The lower sensor 32 analyzes and processes the received signal to obtain the interval width. When the interval width is the interval distance D1 between two adjacent adhesive blocks 93, an adhesive signal is output. When the interval width is the interval distance D2 between the adhesive block 93 and the tab 91 or the interval distance D3 between two adjacent tabs 91, an adhesive shortage signal is output.

[0130] In this embodiment, the edge-following sensing mechanism 3 is electrically connected to the moving mechanism 5, so that the moving mechanism 5 can drive the mounting base 2 to move longitudinally relative to the frame 1 according to the signal when the edge-following sensing mechanism 3 is working, so that the edge-following sensing mechanism 3 can move within the range of the upstream station 220 to detect the tape signal of the upstream station 220 on the tab 200. That is, the edge-following sensing mechanism 3 can automatically move to find the adhesive, so that the edge-following sensing mechanism 3 can smoothly perform the tab adhesive 92 detection work, so as to automatically adapt to the situation where the tab adhesive 92 deviates from the preset position during the production process, without the need for manual monitoring of the detection situation at all times, which can reduce the workload of manual labor and help to realize the automated detection of the tab 200 lacking adhesive.

[0131] refer to Figure 6 The electrode detection device 100 further includes a conductive roller 8 whose axis extends laterally. The conductive roller 8 can be located upstream of the edge-following sensing mechanism 3 or downstream of the probe mechanism 4. Specifically, the conductive roller 8 can be installed and positioned using any frame or other structure.

[0132] The conductive roller 8 is electrically connected to an external power source. The conductive roller 8 is positioned above or below the tab 200 to contact the tab 200, establishing an electrical connection between them. Each first probe 412 and each second probe 422 cooperates with the conductive roller 8 to detect missing adhesive. Compared to existing technologies that use probes against the tab 200, which can easily cause indentations and affect product yield and appearance, and require a corresponding number of probes for the multiple tab strips 91 of the tab 200, this application uses the conductive roller 8 to replace the probes in the prior art. This increases the contact area with the tab 200 (each tab strip 91), avoids stress concentration, prevents indentations, saves on the number of probes, simplifies the structure, and makes maintenance easier.

[0133] The aforementioned tab production equipment boasts high reliability and improved maintenance convenience. Furthermore, it allows for rapid commissioning and efficient adaptation to various tab models. The high manufacturing precision of this equipment improves the yield rate of tab products, making it suitable for the lithium battery industry's stringent tab quality requirements.
