Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing, and in particular to an adhesive applicator and its sheet-making machine. Background Technology

[0002] The electrode sheet enters the equipment via an unwinding device, is positioned according to a preset length, and a single or multiple tabs are welded onto the electrode sheet. The tabs can be welded to the electrode sheet using laser welding or ultrasonic welding processes. After welding the tabs, adhesive tape is applied to them. In current production, the thickness of the adhesive tape applied to the tabs is typically 14-18 micrometers. Existing film-making machines' adhesive application devices can only accommodate adhesive tape thicker than 14 micrometers. When using adhesive tape thinner than 14 micrometers, the tape is easily overstretched, causing air bubbles and wrinkles when applied to the electrode sheet, resulting in poor adhesion. Utility Model Content

[0003] The purpose of this utility model is to provide an adhesive application mechanism and its sheet making machine. The adhesive feeding module clamps and pulls the adhesive paper towards the flipping module. The tension of the adhesive paper is balanced by the adhesive opening roller group. The adhesive paper is fed to the flipping module, pressed by the flipping module, and then cut by the cutting module. The adhesive paper is then stuck on the flipping module and flipped upward. The adhesive application module presses the adhesive paper firmly onto the electrode sheet. It can adapt to adhesive paper with a thickness of more than 10 micrometers. The adhesive paper adheres well to the electrode sheet, without bubbles or wrinkles.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an adhesive applicator, including a base, an adhesive feeding module, a flipping module, an adhesive applicator, and a cutting module disposed on the base. The adhesive feeding module includes a rotatable adhesive feeding disc and an adhesive release roller group disposed in front of the adhesive feeding disc to maintain the tension of the adhesive paper. The adhesive feeding module is used to clamp and convey the adhesive paper wound on the adhesive feeding disc to the flipping module. The cutting module is used to cut the adhesive paper located between the adhesive feeding module and the flipping module. The adhesive applicator pushes and pastes the adhesive paper flipped upward by the flipping module onto the electrode sheet of the sheet making machine.

[0005] This invention employs the aforementioned technical solution. Adhesive paper is wound onto a glue-feeding tray and sequentially passes over the glue-opening roller assembly. The glue-feeding module clamps the adhesive paper and pulls it towards the flipping module. The flipping module flips downwards to press the adhesive paper firmly, and the cutting module cuts the paper. The flipping module then flips upwards to align the adhesive paper with the electrode sheet conveyed on the sheet-making machine. The adhesive-applying module then extends a glue-rolling rod to press the adhesive paper firmly onto the electrode sheet. By maintaining the surface tension of the adhesive paper through the glue-opening roller assembly, a smaller pulling force can be applied to adhesive paper with a thickness of less than 16 micrometers. When the glue-feeding module pulls the adhesive paper to the front of the flipping module and then fixes it, the glue-feeding module moves the adhesive paper backwards a certain distance, providing a buffering effect. This ensures a smooth adhesive paper surface, prevents excessive stretching, and ensures the adhesive paper adheres to the electrode sheet surface without air bubbles or wrinkles.

[0006] The aforementioned adhesive applicator includes a set of fixed and floating adhesive rollers. A side plate is located on the side of the base. The fixed rollers are fixedly mounted on the side plate, while the floating rollers are movably mounted on the side plate. A tension adjusting cylinder is located on the side plate, with its piston rod extending downwards. The adhesive paper is wound around the fixed and floating rollers. The adhesive paper sequentially passes over the fixed and floating rollers. During the adhesive feeding module's pulling of the adhesive paper, the floating rollers can float appropriately on the side of the base, maintaining tension on the adhesive paper. This allows the adhesive feeding module to pull thinner adhesive paper, such as 10-micron thick paper, without tearing or cracking it. The piston rod of the tension adjusting cylinder extends downwards, its extension length contacting the floating rollers and limiting their upward position.

[0007] The aforementioned adhesive applicator has a damper on its side plate, which is connected to the adhesive feeding tray. The adhesive feeding tray is connected to the damper's rotating shaft, and the damper provides damping, so that when the adhesive feeding module stops pulling the adhesive paper, the adhesive feeding tray will not continue to roll due to inertia due to the damping effect of the damper, thus preventing the adhesive paper from falling off the adhesive feeding tray.

[0008] The aforementioned adhesive applicator has a first vertical guide rail on its side plate, and a first slider slidably mounted on the first vertical guide rail. One end of several floating adhesive rollers is connected to the first slider. The floating adhesive rollers are mounted on the first slider. During adhesive feeding, the first slider can move linearly along the first vertical guide rail to adjust the tension of the adhesive tape. During the lifting and lowering of the first slider, the maximum position of its ascent is limited by a piston rod extending downwards from a tension adjusting cylinder.

[0009] The aforementioned adhesive applicator has a base equipped with a pressure cylinder connected to a pressure head. When the pressure head extends, it presses the adhesive paper against one of the fixed adhesive rollers. The pressure cylinder drives the pressure head to extend, pressing the adhesive paper onto the fixed adhesive roller. This prevents the adhesive paper from being pulled downwards by the gravity of the floating adhesive roller after the adhesive feeding and cutting module cuts the adhesive paper, thus preventing the adhesive paper from detaching from the adhesive roller assembly. Furthermore, after the adhesive paper is fixed, the adhesive feeding module clamps the adhesive paper and returns it to its original position a certain distance, allowing the adhesive paper to be released and preventing it from being continuously stretched.

[0010] The aforementioned adhesive applicator includes an adhesive feeding module comprising a first motor mount, a drive motor, a ball screw, a screw flange, a bearing housing, and a clamp, all mounted on a base. The drive motor is mounted on the first motor mount, and its output shaft is connected to the ball screw. The other end of the ball screw is rotatably connected to the bearing housing. The screw flange is threadedly connected to the ball screw, and the clamp is mounted on the screw flange. The drive motor drives the ball screw to rotate, causing it to rotate on the bearing housing. As the ball screw rotates, the screw flange moves along the length of the ball screw via a threaded connection, causing the clamp mounted on the screw flange to move linearly. The clamp clamps one half of the adhesive paper, thereby pulling the adhesive paper to the flipping module position.

[0011] The aforementioned adhesive applicator includes a clamping cylinder, a lower clamping plate, and an upper clamping plate. The clamping cylinder is fixedly connected to the lead screw flange via a nut connecting plate. The lower clamping plate is fixedly mounted on the cylinder body of the clamping cylinder, and the upper clamping plate is opposite to the lower clamping plate. The piston rod of the clamping cylinder is connected to the upper clamping plate. The extension and retraction of the clamping cylinder drives the upper clamping plate to move. The upper and lower clamping plates cooperate to clamp and release the adhesive paper, thereby moving the adhesive paper to the position of the flipping module by clamping the adhesive paper and following the linear movement of the lead screw flange.

[0012] The aforementioned adhesive applicator includes a flipping module comprising an adhesive base, a flipping cylinder, and a flipping connecting plate. The flipping connecting plate is rotatable to the side of the adhesive base via a flipping shaft. The flipping cylinder is connected to and drives the flipping shaft to rotate via a fisheye connector and a cylinder connecting block. The flipping shaft drives the flipping connecting plate to rotate. The flipping connecting plate is equipped with a pressure plate. The flipping cylinder drives the flipping connecting plate to rotate, causing the pressure plate to flip downwards to cooperate with the adhesive base in pressing the adhesive paper, and then flips upwards to move the adhesive paper upwards to align with the electrode sheet. The adhesive feeding module pulls the adhesive paper to the flipping module position, with the bottom surface of the adhesive paper resting on the adhesive base. The flipping cylinder drives the flipping connecting plate to flip relative to the adhesive base, so that when the pressure plate flips downwards, it presses onto the adhesive base to clamp the adhesive paper, and when the pressure plate flips upwards, the adhesive paper adheres to the pressure plate and aligns with the electrode sheet on the electrode sheet making machine.

[0013] The aforementioned adhesive applicator has a flip-fixed ear and a lifting limit block on the side wall of the adhesive base. The flip shaft is rotatably mounted on the flip-fixed ear. An adjusting bolt is threadedly connected to the lifting limit block, and the adjusting bolt is movably connected to the limit block. A limiting protrusion is provided on the outer wall of the flip connecting plate. This limiting protrusion abuts against the limit block when the flip connecting plate flips upward. The adjusting bolt is threaded onto the lifting limit block, which can push the limit block to extend upward and retract downward. When the flip connecting plate flips upward, its limiting protrusion abuts against the limit block. By the limit block abutting against the limiting protrusion, the angle of upward flipping of the flip connecting plate is limited.

[0014] The aforementioned adhesive application mechanism includes an adhesive application base plate and an adhesive application cylinder mounted on the base plate. The base plate is positioned above a foundation. The piston rod of the adhesive application cylinder is connected to an adhesive application bracket, which is rotatably equipped with a glue roller. When the piston rod of the adhesive application cylinder extends, it pushes the adhesive application bracket toward the flipping module. The glue roller then contacts and pushes the adhesive paper, causing it to detach from the flipping module and adhere to the electrode sheet being conveyed on the sheet-making machine.

[0015] The aforementioned adhesive applicator has an outer vertical plate on the base, with a second vertical guide rail on the plate. The adhesive applicator base plate slides on the second vertical guide rail via a second slider. Above the base, there is an adjusting screw seat and an adjusting screw. The adjusting screw seat is fixed to the vertical plate, and the adjusting screw is threadedly connected to the adjusting screw seat, with its bottom end extending downwards to abut against the surface of the adhesive applicator base plate. The adjusting screw, through the threaded connection, can move vertically relative to the adjusting screw seat. The end of the adjusting screw can abut against the upper surface of the adhesive applicator base plate, thereby limiting the upward position of the adhesive applicator base plate. The lifting position of the adhesive applicator base plate is adjustable, and the adhesive roller can reliably press and adhere adhesive paper at different heights onto the electrode sheet.

[0016] The aforementioned adhesive applicator includes a cutting module comprising a cutting cylinder and a cutting mounting base connected to the cylinder. The mounting base is equipped with an adhesive applicator cutter, and the pressure plate has a cutting through hole through which the cutter can pass. The cutting cylinder drives the mounting base and the cutter cutter to rise upwards, pass through the cutting through hole, and cut the adhesive paper.

[0017] The aforementioned adhesive application mechanism includes a base comprising a supporting base plate and a movable base plate slidably mounted on the supporting base plate. A correction motor is mounted on the underside of the supporting base plate via a second motor mount. The correction motor is connected to a rotating lead screw, and a correction nut seat is threaded onto the rotating lead screw. The correction nut seat is connected to the movable base plate. The correction motor drives the correction nut seat to move linearly along the rotating lead screw, controlling the movable base plate to follow the correction nut seat in a linear motion, thereby adjusting the position of the movable base plate relative to the supporting base plate. By adjusting the position of the movable base plate, the position of the flipping module relative to the electrode sheet is adjusted.

[0018] The aforementioned adhesive application mechanism features a long through-hole on the supporting base plate. The alignment nut seat is connected to the movable base plate via a base connecting plate, which can move within the long through-hole. This design, with the long through-hole on the supporting base plate and the base connecting plate on the alignment nut seat connecting to and moving within the long through-hole, simplifies the connection structure between the supporting base plate and the movable base plate.

[0019] The aforementioned adhesive application mechanism includes an adjustment plate, an adjustment seat, a sliding bracket, and an optical fiber plate on the side of the movable base plate. The adjustment seat has a micrometer head fixing seat and an optical axis fixing seat at both ends. An optical axis is fixed between the micrometer head fixing seat and the optical axis fixing seat. The sliding bracket is slidably mounted on the optical axis. The micrometer head fixing seat has a micrometer knob for abutting the sliding bracket. A spring is provided between the sliding bracket and the optical axis fixing seat. The optical fiber plate is connected to the adjustment bracket and is Y-shaped. Optical fiber sensors are located at both ends of the Y-shaped opening, on the front and rear sides of the electrode, respectively. The optical fiber sensors are located on both sides of the electrode to detect the position of the electrode, provide feedback on the detection information, and determine whether it is necessary to drive the correction motor to adjust the position of the movable base plate, thereby achieving the correction purpose.

[0020] This utility model also provides another technical solution: a film-making machine, which includes the adhesive applicator described in any of the above-mentioned claims.

[0021] This invention relates to a film-making machine. Adhesive paper is wound onto a glue feeding tray. One end of the adhesive paper is pulled out and sequentially wound onto a fixed glue roller and a floating glue roller. A drive motor drives a lead screw flange to perform linear reciprocating motion on a ball screw, which in turn drives a clamping device to move linearly. After the clamping device pulls the adhesive paper to a set position, a glue-applying cylinder drives a glue-rolling rod to extend and push the adhesive paper onto the electrode sheet. This film-making machine can use thinner adhesive paper for application, and the adhesive application effect on the electrode sheet is good, without air bubbles or wrinkles.

[0022] The beneficial effects of this invention are as follows: By balancing the tension of the adhesive paper with a floating rubber roller, the glue feeding module pulls half of the adhesive paper. After being pulled into position, the glue pressing cylinder drives the glue pressing head to press the adhesive paper onto the fixed rubber roller. Then, the glue feeding module drives the clamp to retreat a certain distance, thus buffering the tension received by the adhesive paper and preventing it from being constantly taut. When the clamp releases the adhesive paper, the adhesive paper will not slip off the fixed and floating rubber rollers because the glue pressing head is pressed against the fixed rubber roller. This adhesive applicator can adhere adhesive paper with a thickness of less than 16 micrometers to the electrode sheet and can ensure the adhesive application effect, making the adhesive paper adhered to the electrode sheet without air bubbles, with a uniform surface, and without wrinkles. When applied to a film-making machine, it can achieve adhesive application of adhesive paper with a thickness of 10 micrometers and above, such as 10-micrometer thick adhesive paper, thus broadening the application range of film-making machines for adhesive paper of different thicknesses and improving production efficiency.

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figures 1 to 15As shown, an adhesive applicator includes a base 1, an adhesive feeding module 2, a flipping module 3, an adhesive applicator 4, and a cutting module 5 mounted on the base 1. The adhesive feeding module 2 includes a rotatable adhesive feeding disc 201 and an adhesive release roller group 21 located in front of the adhesive feeding disc 201 to maintain the tension of the adhesive paper. The adhesive feeding module 2 is used to clamp and convey the adhesive paper 6 wound on the adhesive feeding disc 201 to the flipping module 3. The cutting module 5 is used to cut the adhesive paper 6 located between the adhesive feeding module 2 and the flipping module 3. The adhesive applicator 4 pushes and adheres the adhesive paper 6 flipped upward by the flipping module 3 onto the electrode sheet 7 of the sheet-making machine. The back of the electrode sheet 7 is supported by an adhesive applicator back roller 406 on the sheet-making machine. The glue feeding module 2 rotates the glue feeding disc 201, outputting the adhesive paper 6 wound on it. At the same time, the clamp on the glue feeding module 2 clamps the adhesive paper 6 and pulls it forward. After pulling the adhesive paper 6 to the position of the flipping module 3, the glue feeding module 2 can return to the rear a little distance. Then the clamp 23 releases the adhesive paper 6, the glue feeding module 2 moves backward and the clamp 23 returns to the rear, leaving the front end of the adhesive paper 6. Then the flipping module 3 flips down and presses the adhesive paper 6. Then the cutter module 5 cuts the adhesive paper. At this time, the flipping module 3 flips the adhesive paper on it upward, aligning it with the electrode 7 on the adhesive back roller 406. The adhesive application module 4 moves forward and pushes the cut adhesive paper forward, so that the adhesive paper 6 is attached and pasted on the electrode 7, completing one adhesive application operation.

[0041] The adhesive stripping roller assembly 21 includes several fixed adhesive rollers 211 and several floating adhesive rollers 212. A side plate 202 is provided on the side of the base 1. The fixed adhesive rollers 211 are fixedly mounted on the side plate 202, and the floating adhesive rollers 212 are movably mounted on the side plate 202. A tension adjusting cylinder 203 is provided on the side plate 202. The piston rod of the tension adjusting cylinder 203 extends downwards, and the adhesive paper 6 is wound around the fixed adhesive rollers 211 and the floating adhesive rollers 212. Figure 11 As shown, in this embodiment, the number of fixed rubber rollers 211 is set to 5, and the number of floating rubber rollers 212 is set to 2. In other embodiments, the number of fixed rubber rollers 211 and floating rubber rollers 212 can be determined according to the thickness of different adhesive paper, depending on the actual situation.

[0042] Furthermore, a damper 204 is provided on the side plate 202, and the damper 204 is connected to the glue feeding tray 201. In this embodiment, the damper 204 is used to provide damping so that when the clamp 23 clamps and pulls the adhesive paper into place and stops pulling the adhesive paper, the glue feeding tray 201 is prevented from rotating forward due to inertia due to the resistance provided by the damper 204, thus preventing the adhesive paper 6 from falling off the glue feeding tray 201.

[0043] A first vertical guide rail 205 is provided on the side plate 202, and a first slider 206 is slidably mounted on the first vertical guide rail 205. One end of several floating rubber rollers 212 is connected to the first slider 206. The first slider 206 can move up and down vertically on the first vertical guide rail 205. One end of the floating rubber rollers 212 is connected to the first slider 206. When the glue feeding module 2 pulls the adhesive paper 6 forward, the adhesive paper 6 can drive the floating rubber rollers 212 to move up and down on the first vertical guide rail 205 via the first slider 206, thereby balancing the force on the adhesive paper 6. Specifically, the floating rubber rollers 212 and the fixed rubber rollers 211 are arranged on the side plate 202, and the adhesive paper 6 passes around the fixed rubber rollers 211 and the floating rubber rollers 212, as shown in the figure. Figure 5 As shown, the fixed rubber roller 211, the floating rubber roller 212, and the adhesive paper 6 wound on them can form a pulley system. The fixed rubber roller 211 forms a fixed pulley, and the floating rubber roller 212 forms a movable pulley. The adhesive paper 6 can reduce the tension it receives by passing around the floating rubber roller 212. In addition, with the cooperation of the glue-opening roller group 21, the tension of the adhesive paper 6 on the clamp 23 of the glue-feeding module 2 is reduced. This adhesive applicator can be used for adhesive paper with a smaller thickness, such as 10 micrometers thick adhesive paper.

[0044] A glue-pressing cylinder 207 is provided on the base 1, and a glue-pressing head 208 is connected to the glue-pressing cylinder 207. When the glue-pressing head 208 extends, it presses the adhesive paper onto one of the fixed glue rollers 211. When the clamp 23 clamps the adhesive paper, the glue feeding module 2 drives the clamp 23 to move forward into position, and then the glue-pressing cylinder 207 drives the glue-pressing head 208 to press the adhesive paper onto one of the fixed glue rollers 211. This prevents the adhesive paper 6 from being continuously stretched when the clamp 23 moves the adhesive paper 6 back a certain distance. When the glue-pressing head 208 presses the adhesive paper onto the fixed glue roller 211, and the cutting module 5 cuts the adhesive paper pressed by the flipping module 3, the adhesive paper 6 will not slip off the glue-opening roller group 21.

[0045] Reference Figure 5 , Figure 6As shown, the glue feeding module 2 includes a first motor base 221, a drive motor 222, a ball screw 223, a screw flange 224, a bearing seat 225, and a clamp 23, all mounted on the base 1. The drive motor 222 is mounted on the first motor base 221, and its output shaft is connected to the ball screw 223. The other end of the ball screw 223 is rotatably connected to the bearing seat 225. The screw flange 224 is threaded onto the ball screw 223, and the clamp 23 is mounted on the screw flange 224. The drive motor 222 drives the ball screw 223 to rotate. During the rotation of the ball screw 223, the screw flange 224 is threadedly connected to the ball screw 223. Specifically, the screw flange 224 is threadedly sleeved on the ball screw 223. When the ball screw 223 rotates, the screw flange 224 moves along the length of the ball screw 223, which drives the clamp 23 connected to the screw flange 224 to move. The clamp 23 clamps one half of the adhesive paper 6 and moves the adhesive paper 6 toward the flipping module 3. When the adhesive paper 6 is moved onto the flipping module 3, the flipping module 3 can press the other half of the adhesive paper 6. Then the clamp 23 releases the adhesive paper and moves backward to reset under the drive of the drive motor 222.

[0046] Further reference Figure 5 , 6 The clamp 23 includes a clamp cylinder 231, a lower clamping plate 232, and an upper clamping plate 233. The clamp cylinder 231 is fixedly connected to the lead screw flange 224 via a nut connecting plate 226. The lower clamping plate 232 is fixedly mounted on the cylinder body of the clamp cylinder 231. The upper clamping plate 233 is opposite to the lower clamping plate 232, and the piston rod of the clamp cylinder 231 is connected to the upper clamping plate 233. The clamp cylinder 231 drives the upper clamping plate 233 to open and close relative to the lower clamping plate 232, thereby clamping and releasing the adhesive paper.

[0047] Reference Figure 7 and Figure 8As shown, the flip module 3 includes an adhesive base 301, a flip cylinder 311, and a flip connecting plate 312. The flip connecting plate 312 is rotatable to the side of the adhesive base 301 via a flip shaft 313. The flip cylinder 311 is connected to and drives the flip shaft 313 to rotate via a fisheye connector 314 and a cylinder connecting block 315. The flip shaft 313 drives the flip connecting plate 312 to rotate. The flip connecting plate 312 is provided with a pressure plate 316. The flip cylinder 311 drives the flip connecting plate 312 to rotate, causing the pressure plate 316 to flip downward to cooperate with the adhesive base 301 to press the adhesive paper 6, and then flips upward to move the adhesive paper 6 upward to align with the electrode 7. The piston rod of the flipping cylinder 311 is connected to one end of the fisheye connector 314. The fisheye connector 314 is rotatably connected to the cylinder connecting block 315. When the piston rod of the flipping cylinder 311 drives the fisheye connector 314 to move, the fisheye connector 314 drives the cylinder connecting block 315 to rotate. The cylinder connecting block 315 is sleeved on the flipping shaft 313 and fixedly connected. The cylinder connecting block 315 drives the flipping shaft 313 to rotate, which in turn drives the flipping connecting plate 312 to rotate. When the flipping connecting plate 312 flips downward, it drives the pressure plate 316 to press down on the adhesive paper 6 padding on the adhesive seat 301. After the cutting module 5 cuts the adhesive paper, the adhesive paper is adhered to the pressure plate 316. When the flipping cylinder 311 drives the flipping connecting plate 312 to flip upward, the pressure plate 316 flips upward. When the adhesive paper on the pressure plate 316 is aligned with the electrode 7 on the film making machine, the adhesive paper is pressed and pasted onto the electrode 7 by the adhesive application module 4.

[0048] Furthermore, the adhesive base 301 has a flip-fixed ear 302 and a lifting limit block 303 on its side wall. The flip shaft 313 is rotatably mounted on the flip-fixed ear 302. An adjusting bolt 304 is threadedly connected to the lifting limit block 303. The adjusting bolt 304 is movably connected to a limit block 305. The outer side wall of the flip connecting plate 312 has a limiting protrusion 318, which abuts against the limit block 305 when the flip connecting plate 312 flips upward. When the flip cylinder 311 drives the flip connecting plate 312 to rotate, the flip shaft 313 can rotate on the flip-fixed ear 302 and is threadedly connected to the adjusting bolt 304. When the adjusting bolt 304 is turned, it can move relative to the lifting limit block 303 along the axis of the adjusting bolt 304. The adjusting bolt 304 is movably connected to the limit block 305 and drives the limit block 305 to extend upward or retract downward relative to the lifting limit block 303. When the flip connecting plate 312 flips upward, the limiting protrusion 318 on its outer side wall can abut against the limiting block 305, thereby achieving a positioning function. By adjusting the bolt 304 to control the position of the limiting block 305 extending out of the lifting limiting block 303, the flipping angle of the flip connecting plate 312 can be adjusted.

[0049] Combination Figure 9 and 10As shown, the adhesive application module 4 includes an adhesive application base plate 411 and an adhesive application cylinder 412 mounted on the adhesive application base plate 411. The adhesive application base plate 411 is located above the base 1. The piston rod of the adhesive application cylinder 412 is connected to an adhesive application bracket 413, and the adhesive application bracket 413 is rotatably equipped with a glue roller 414. The piston rod of the adhesive application cylinder 412 pushes the glue roller 414 forward. The glue roller 414 can rotate on the adhesive application bracket 413. When it contacts the adhesive paper 6, the glue roller 414 can better press the adhesive paper 6 firmly onto the electrode 7.

[0050] A vertical plate 401 is provided on the outer side of the base 1, and a second vertical guide rail 402 is provided on the vertical plate 401. The adhesive base plate 411 slides on the second vertical guide rail 402 via a second slider 403. An adjusting screw seat 404 and an adjusting screw 405 are also provided above the base 1. The adjusting screw seat 404 is fixedly mounted on the vertical plate 401, and the adjusting screw 405 is threadedly connected to the adjusting screw seat 404, with its bottom end extending downward to abut against the surface of the adhesive base plate 411. By moving the second slider 403 along the vertical direction of the second vertical guide rail 402, the vertical position of the adhesive base plate 411 and the roller 414 mounted on the adhesive base plate 411 is adjusted to better adhere the adhesive paper 6 to the electrode 7.

The cutter mounting base 512 is provided with an adhesive-applying cutter 513, and the pressure plate 316 is provided with a cutting through hole 317 through which the adhesive-applying cutter 513 can pass. The cutter cylinder 511 drives the cutter mounting base 512 to rise, causing the adhesive-applying cutter 513 to pass through the cutting through hole 317 on the pressure plate 316. When the adhesive-applying cutter 513 passes through the cutting through hole 317, it cuts the adhesive paper.

[0052] Reference Figure 14 , 15 As shown, the base 1 includes a supporting base plate 11 and a movable base plate 12 slidably mounted on the supporting base plate 11. A correction motor 112 is mounted on the bottom side of the supporting base plate 11 via a second motor base 111. The correction motor 112 is connected to a rotating lead screw 113, and a correction nut seat 114 is threaded onto the rotating lead screw 113. The correction nut seat 114 is connected to the movable base plate 12. The correction motor 112 drives the rotating lead screw 113 to rotate, and the rotating lead screw 113 causes the correction nut seat 114 to move linearly along the axial direction of the rotating lead screw 113. The correction nut seat 114 causes the movable base plate 12 to move relative to the supporting base plate 11, thereby adjusting the positions of the glue feeding module 2, the flipping module 3, the adhesive application module 4, and the cutting module 5.

[0053] Specifically, the support base plate 11 is provided with an elongated through hole 110, and the correction nut seat 114 is connected to the movable base plate 12 through the base connecting plate 115. The base connecting plate 115 can move in the elongated through hole 110.

[0054] Reference Figure 11 and 12 As shown, the side of the movable base plate 12 is provided with an adjustment plate 121, an adjustment seat 122, a sliding bracket 123 and an optical fiber plate 124.

The adjusting plate 121 is also equipped with a locking knob 120 and a slotted hole. The locking knob 120 passes through the slotted hole and connects to the adjusting seat 122. After the adjusting seat 122 is positioned on the adjusting plate 121, the locking knob 120 is turned to fix the position of the adjusting seat 122. The adjusting seat 122 can move along the length of the slotted hole on the adjusting plate 121, thereby adjusting the position of the fiber optic sensor 130 detecting the electrode 7.

[0055] This utility model also discloses a film-making machine, which includes the adhesive applicator mechanism described in the above specific embodiments.

[0056] In a specific implementation of this invention, adhesive tape 6 is first wound around the glue feeding tray 201. The adhesive tape passes through the glue-opening roller group 21 and is sequentially wound around the fixed glue roller 211 and the floating glue roller 212. One end of the adhesive tape 6 passes over the glue-opening roller group 21 and is placed on the adhesive tape pad 24, with one half of the adhesive tape 6 protruding from the outside of the adhesive tape pad 24. During operation, the glue feeding module 2 is activated, and the clamp 23 is activated, driving the upper clamping plate 233 to move downward to the lower clamping plate 232, clamping one half of the adhesive tape 6. Then, the drive motor 222 is started, driving the ball screw 223 to rotate. When the ball screw 223 rotates, it drives the screw flange 224 to move linearly on the ball screw 223, causing the clamp 23 to clamp the adhesive tape 6 and move it towards the flipping module 3. When the adhesive tape 6 moves to the adhesive base 301, the pressure cylinder 207 drives the pressure head 208 to extend, pressing the adhesive tape firmly onto one of the fixed adhesive rollers 211. At this time, the drive motor 222 drives the clamp 23 to pull the adhesive tape backward a certain distance, thus buffering the adhesive tape 6 and preventing it from being stretched continuously. The flipping module 3 is activated, the piston rod of the flipping cylinder 311 extends, and drives the flipping connecting plate 312 to flip downward through the fisheye connector 314 and the cylinder connecting block 315, so that the pressure plate 316 presses down onto the adhesive base 301, and at the same time presses the other half of the adhesive tape 6. When the pressure plate 316 and the adhesive base 301 press the adhesive tape together, the clamp 23 releases the adhesive tape 6, the drive motor 222 drives the clamp 23 to move backward to reset, and at the same time clamps the next section of adhesive tape. At this time, the cutting module 5 is activated, and the cutting cylinder 511 drives the adhesive cutting blade 513 to move upward, simultaneously passing through the cutting through hole 317 of the pressure plate 316 and cutting the adhesive paper located between the clamp 23 and the pressure plate 316. The piston rod of the flipping cylinder 311 drives the fisheye connector 314 and the cylinder connecting block 315 to move, causing the flipping connecting plate 312 to flip upward, and causing the pressure plate 316 to flip upward. The cut adhesive paper is pasted on the pressure plate 316. When the limiting protrusion 318 on the flipping connecting plate 312 touches the abutting limit block 305, the pressure plate 316 flips upward into place. When the adhesive application module 4 is activated, the piston rod of the adhesive application cylinder 412 extends, pushing the adhesive application bracket 413 to extend. The adhesive strip 6 on the pressure plate 316 is pressed onto the electrode sheet 7 conveyed on the die-making machine by the adhesive roller 414. An adhesive application back roller 406 is provided on the back side of the electrode sheet 7, which supports and conveys the electrode sheet 7. This back roller 406 helps to better adhere the adhesive strip 6 to the electrode sheet 7 when the adhesive roller 414 presses it down. Once the adhesive strip is adhered to the electrode sheet 7, the adhesive application cylinder 412 drives the adhesive application bracket 413 and the adhesive roller 414 to retract back to their original positions.
