Description

Technical Field

[0002] In the production process of lithium battery electrodes, a turret unwinding device is generally used for unwinding. The turret unwinding device has two reels, each of which is loaded with coils. The two reels unwind the coils alternately. After the coil on one of the reels is produced, the empty reel on the turret unwinding device needs to be unloaded, and the foil on the new coil needs to be glued to the foil at the tape path to continue production.

[0003] Conventional new coils have several labels attached to the foil head. Before loading the new coils into the turret unwinding equipment, the new coils need to be pre-processed. First, tear off the labels attached to the new coils, cut off the contaminated and bumped foil on the outer layer of the new coils and keep a sample. Then, spray adhesive on the back of the foil head and press it back onto the coil. Finally, stick double-sided tape on the cut of the head and remove the release paper to ensure the success rate of the subsequent automatic splicing process.

[0004] However, when applying the double-sided tape, the glue roller presses the tape above the cut of the material head of the foil coil. The material head of the foil coil is only subjected to force at the highest point of the arc surface close to the glue roller side, and the low point of the arc surface of the material head of the foil coil is not subjected to force. As a result, the double-sided tape is not in complete contact with the material head of the foil coil, and the double-sided tape is easy to fall off, affecting the success rate of subsequent splicing.

[0033] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0034] Reference Figures 1 to 4 , an embodiment of a coil material pre-processing device is provided, comprising a frame 10 and a coil material head gluing mechanism arranged on the frame 10. Positionally, the frame 10 is located on one radial side of the foil material coil.

[0035] Specifically, the coil material head gluing mechanism includes a moving component 1, a base plate 2 arranged on the moving component 1, a reeling component 3 arranged on the base plate 2, a glue cutting component 4, a gluing component 5, a glue pressing component 6, a reeling component 7 and a plurality of rollers 8. The moving direction of the moving component 1 extends along the axial direction of the foil coil 9.

[0036] In terms of position, the glue cutting assembly 4 is located between the unwinding assembly 3 and the glue sticking assembly 5, and the glue pressing assembly 6 is located on one side of the glue sticking assembly 5. A plurality of rollers 8 are sequentially arranged between the unwinding assembly 3 and the glue cutting assembly 4, between the glue cutting assembly 4 and the glue sticking assembly 5, and between the glue sticking assembly 5 and the unwinding assembly 3.

[0037] Functionally, the unwinding component 3 is used to unwind the double-sided adhesive tape 33, the glue cutting component 4 is used to cut the tape on the double-sided adhesive tape 33, the gluing component 5 is used to stick the tape to the top of the material head cut of the foil coil 9, the glue pressing component 6 is used to press the tape stuck to the top of the material head cut of the foil coil 9, and the winding component 7 is used to wind up the release paper of the double-sided adhesive tape 33.

[0038] Structurally, the gluing assembly 5 includes a first support 51, a gluing roller 52 and a first power member 53. The gluing roller 52 is rotatably connected to the first support 51. The first support 51 is arranged at the output end of the first power member 53. The first power member 53 is used to drive the first support 51 and the gluing roller 52 to approach or move away from the foil coil 9.

[0039] Furthermore, the glue pressing assembly 6 includes a first re-pressing module 61 and / or a second re-pressing module 62 .

[0040] The first re-pressing module 61 includes a second support 611, a first re-pressing roller 612, a second re-pressing roller 613 and a second power member 614. The first re-pressing roller 612 and the second re-pressing roller 613 are both rotatably connected to the second support 611. The second support 611 is arranged at the output end of the second power member 614. The middle part of the first re-pressing roller 612 is sleeved with a first flexible anti-sticking rubber sleeve 6121, and the two sides of the second re-pressing roller 613 are respectively sleeved with second flexible anti-sticking rubber sleeves 6131. ​​The second power member 614 drives the second support 611 to approach or move away from the foil coil 9, so as to drive the first re-pressing roller 612 and the second re-pressing roller 613 to press or loosen the tape adhered to the foil coil 9 in turn.

[0041] The second re-pressing module 62 includes a third support 621, a third re-pressing roller 622 and a third power member 623. The third re-pressing roller 622 is rotatably connected to the third support 621. The third support 621 is arranged at the output end of the third power member 623. The two sides of the third re-pressing roller 622 are respectively sleeved with a third flexible anti-sticking rubber sleeve 6221. The third power member 623 is used to drive the third support 621 and the third re-pressing roller 622 to approach or move away from the foil coil 9.

[0042] It should be noted that the first power member 53 , the second power member 614 and the third power member 623 may be cylinders, or may be electric cylinders, oil cylinders or other power members capable of realizing telescopic motion.

[0043] Specifically, the diameter of the second flexible anti-sticking rubber sleeve 6131 gradually increases from the middle to the end of the second re-pressing roller 613, so that the surface of the second flexible anti-sticking rubber sleeve 6131 forms an arc surface, and the diameter of the third flexible anti-sticking rubber sleeve 6221 gradually increases from the middle to the end of the third re-pressing roller 622, so that the surface of the third flexible anti-sticking rubber sleeve 6221 forms an arc surface, and the surface curvature of the second flexible anti-sticking rubber sleeve 6131 is greater than the surface curvature of the third flexible anti-sticking rubber sleeve 6221, thereby making the surface of the second flexible anti-sticking rubber sleeve 6131 fit the arc surface of the foil roll 9 with a smaller winding diameter, and making the surface of the third flexible anti-sticking rubber sleeve 6221 fit the arc surface of the foil roll 9 with a larger winding diameter, thereby improving the degree of fit between the two side positions in the width direction of the tape and the arc surface of the foil roll 9

[0044] When the coil diameter of the foil coil 9 is small, the first re-pressing module 61 is used to press the tape pasted on the material head cut of the foil coil 9. Specifically, before gluing, the double-sided adhesive tape 33 is unwound from the unwinding assembly 3 and wound around a plurality of rollers 8 in sequence, so that the double-sided adhesive tape 33 passes through the glue cutting assembly 4, the glue sticking assembly 5 and the winding assembly 7 in sequence. The bottom plate 2 is located at a standby position on one side of the foil coil 9. It should be noted that the tape end of the double-sided adhesive tape 33 is located at a position corresponding to the glue sticking roller 52. When gluing, the first power member 53 drives The movable glue roller 52 approaches the foil coil 9 and sticks the adhesive tape to one end of the material head cut of the foil coil 9. Then, the moving component 1 drives the bottom plate 2 to move along the axial direction of the coil. At the same time, the unwinding component 3 unwinds the double-sided adhesive tape 33, and the rewinding component 7 rewinds the release paper of the double-sided adhesive tape 33. Before the adhesive tape is attached to the other end of the material head cut of the foil coil 9, the glue cutting component 4 cuts off the adhesive tape on the double-sided adhesive tape 33. The moving component 1 drives the bottom plate 2 to continue to move, so that the glue roller 52 completely sticks the cut adhesive tape to the material head cut of the foil coil 9. Then, the first power member 53 drives the adhesive roller 52 away from the foil coil 9, and the unwinding assembly 3 and the winding assembly 7 stop working. At the same time, the moving assembly 1 drives the bottom plate 2 to move in the opposite direction, and the second power member 614 drives the second support 611 to approach the foil coil 9 to drive the first re-pressing roller 612 and the second re-pressing roller 613 to press the adhesive tape pasted on the foil coil 9 in turn. At this time, the first flexible anti-adhesive rubber sleeve 6121 on the first re-pressing roller 612 presses the middle position of the adhesive tape in the width direction, and the second flexible anti-adhesive rubber sleeve 6121 on the first re-pressing roller 612 presses the middle position of the adhesive tape in the width direction. The surface curvature of the adhesive sleeve 6131 is relatively large, which is convenient for fitting with the curved surface of the foil coil 9 with a smaller winding diameter. The second flexible anti-sticking adhesive sleeves 6131 on both sides of the second re-pressing roller 613 respectively press the two side positions in the width direction of the tape. Finally, the moving component 1 drives the bottom plate 2 to move to the standby position, and the second power member 614 drives the second support 611 away from the foil coil 9, so that the two side positions in the width direction of the tape can be completely fitted on the curved surface of the foil coil 9, thereby improving the success rate of subsequent tape splicing.

[0045] When the coil diameter of the foil coil 9 is large, the second re-pressing module 62 is used to press the tape pasted on the material head cut of the foil coil 9. Specifically, before gluing, the double-sided adhesive tape 33 is unwound from the unwinding assembly 3 and wound around a plurality of rollers 8 in sequence, so that the double-sided adhesive tape 33 passes through the glue cutting assembly 4, the glue sticking assembly 5 and the winding assembly 7 in sequence. The bottom plate 2 is located at a standby position on one side of the foil coil 9. It should be noted that the tape end of the double-sided adhesive tape 33 is located at a position corresponding to the glue sticking roller 52. When gluing, the first power member 53 drives the gluing roller 52 to approach the foil coil 9 and stick the adhesive tape to one end of the material head cut of the foil coil 9. Then, the moving component 1 drives the bottom plate 2 to move along the axial direction of the coil. At the same time, the unwinding component 3 unwinds the double-sided adhesive tape 33, and the rewinding component 7 rewinds the release paper of the double-sided adhesive tape 33. Before the adhesive tape is attached to the other end of the material head cut of the foil coil 9, the glue cutting component 4 cuts off the adhesive tape on the double-sided adhesive tape 33, and the moving component 1 drives the bottom plate 2 to continue moving. The glue sticking roller 52 completely sticks the cut tape on the material head cut of the foil coil 9, and then the first power member 53 drives the glue sticking roller 52 away from the foil coil 9, the unwinding assembly 3 and the winding assembly 7 stop working, and at the same time, the moving assembly 1 drives the bottom plate 2 to move in the opposite direction, and the third power member 623 drives the third support 621 to approach the foil coil 9 to drive the third re-pressing roller 622 to press the tape stuck on the foil coil 9, the surface curvature of the third flexible anti-adhesive rubber sleeve 6221 is small, which is convenient for fitting with the curved surface of the foil coil 9 with a larger roll diameter, and the third flexible anti-adhesive rubber sleeves 6221 on both sides of the third re-pressing roller 622 respectively press the two side positions in the width direction of the tape, and finally, the moving assembly 1 drives the bottom plate 2 to move to the standby position, and the third power member 623 drives the third support 621 away from the foil coil 9, so that the two side positions in the width direction of the tape can be completely fitted on the curved surface of the foil coil 9, thereby improving the success rate of subsequent tape splicing.

[0046] In some preferred embodiments, the adhesive cutting assembly 4 includes a cutter 41 and a fourth power member 42 . The fourth power member 42 is used to drive the cutter 41 to move closer to or away from the adhesive tape, thereby being able to cut the adhesive tape on the double-sided adhesive tape 33 .

[0047] Specifically, a knife seat 43 and a pressure block 44 are provided at the output end of the fourth power member 42 , and the cutter 41 is arranged between the knife seat 43 and the pressure block 44 . The pressure block 44 is connected to the knife seat 43 by bolts, so that the cutter 41 is easy to replace.

[0048] Furthermore, the fourth power part 42 is a cylinder, a slider 45 is provided on one side of the knife seat 43, a slide rail 46 is provided on one side of the cylinder, the slider 45 is slidably connected to the slide rail 46, the slider 45 is connected to the cylinder through a connecting block 47, a stopper 48 is provided on one side of the slider 45, and a limit rod 49 is provided on the other side of the cylinder. When the cylinder drives the slider 45 to move to drive the stopper 48 to approach and abut one end of the limit rod 49, the cylinder stops moving, thereby being able to accurately control the moving position of the cutter 41, so that the cutter 41 can cut the tape of the double-sided adhesive 33 without cutting the release paper of the double-sided adhesive 33, thereby ensuring that the tape will not break when the release paper is rolled up.

[0049] Furthermore, another limit rod 49 is also provided on the side of the cylinder away from the telescopic end, and one end of the limit rod 49 corresponds to one side of the slider 45. When the cylinder retracts, the cylinder drives the slider 45 to move to approach and abut against one end of the limit rod 49, and the cylinder stops moving, thereby being able to accurately control the telescopic amount of the cylinder.

[0050] Specifically, the limit rod 49 is installed on the side of the cylinder through a fixing seat, and the fixing seat is provided with a threaded hole. The limit rod 49 is a top screw or a screw rod. The position of the limit rod 49 is adjusted by screwing out the length of the top screw or the screw rod, and is fixed by a nut. This can prevent mechanical vibration from affecting the positioning accuracy, thereby facilitating the adjustment of the moving position of the cutter 41.

[0051] Furthermore, the glue cutting assembly 4 also includes a cutting board 40, which has a cutting surface 401. The edge of the cutter 41 is opposite to the cutting surface 401, and the double-sided tape 33 passes between the cutting surface 401 and the edge of the cutter 41. The cutting board 40 can support the double-sided tape 33 so that the double-sided tape 33 is spread flat on the cutting surface 401, thereby avoiding the phenomenon that the cutter 41 cannot cut the double-sided tape 33 due to deformation of the double-sided tape 33 when cutting the tape.

[0052] In some preferred embodiments, the unwinding assembly 3 includes an unwinding roller 31 and a first motor 32. In terms of position, the unwinding roller 31 is located at the top of the base plate 2, and the first motor 32 is located at the bottom of the base plate 2. The output shaft of the first motor 32 passes through the base plate 2 and is connected to the unwinding roller 31. The roll of double-sided tape 33 is mounted on the unwinding roller 31. The first motor 32 drives the unwinding roller 31 to rotate to drive the roll of double-sided tape 33 to be unwound.

[0053] Furthermore, the winding assembly 7 includes a winding roller 71 and a second motor 72. In terms of position, the winding roller 71 is located at the top of the base plate 2, and the second motor 72 is located at the bottom of the base plate 2. The output shaft of the second motor 72 passes through the base plate 2 and is connected to the winding roller 71. The roll of release paper is installed on the winding roller 71. The second motor 72 drives the winding roller 71 to rotate to drive the roll of release paper to be wound.

[0054] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
