Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, specifically a material strip changing device and winding equipment. Background Technology

[0002] In the battery production process, adhesive application is required. For example, after the battery cell is wound, finishing tape is applied to the cell to prevent it from becoming loose. Generally, the tape material is supplied in rolls. First, the tape roll is rotated to unwind and output the tape downstream. Then, the output tape is cut into strips of a certain length, and finally, the tape is applied to the battery cell.

[0003] However, once the tape roll is unwound, a new roll needs to be manually replaced, and the tape needs to be manually threaded. The automation level is low, and the labor intensity is high. Utility Model Content

[0004] Therefore, it is necessary to provide a tape changing device and winding equipment that can automatically change the tape roll to address the above problems.

[0005] A tape changing device, comprising:

[0006] An unwinding mechanism includes a moving part and at least two unwinding shafts disposed on the moving part. The unwinding mechanism has a connecting station and an unwinding station, and the unwinding shaft located at the unwinding station is used to unwind the output strip.

[0007] A tape receiving mechanism is provided, which forms a tape receiving channel with the unwinding shaft located at the connecting station. The tape receiving channel allows the tape unwound from the unwinding shaft at the unwinding station to pass through. The tape receiving mechanism includes a first pressing assembly and a first cutting assembly. The first pressing assembly includes a first pressing drive and a first pressure roller mounted on the drive end of the first pressing drive. The first cutting assembly includes a first cutting drive and a first cutter mounted on the drive end of the first cutting drive, and the first cutter is located upstream of the first pressure roller.

[0008] In some embodiments, the first pressing drive can drive the first pressure roller to press the strip passing through the tape receiving channel against the roll on the unwinding shaft located at the connecting station.

[0009] In some embodiments, the first cutting drive can drive the first cutter to cut the strip passing through the tape channel.

[0010] In some embodiments, the first pressing assembly is configured to be at least two; or, the first pressing assembly includes at least two first pressing rollers, each of which is mounted on the drive end of the first pressing drive.

[0011] In some embodiments, the unwinding mechanism further includes a support roller disposed between the downstream of the unwinding station and the upstream of the connecting station.

[0012] In some embodiments, the belt feeding mechanism further includes a second pressing assembly, which includes a second pressing drive and a second pressure roller mounted on the drive end of the second pressing drive, the second pressure roller being arranged opposite to the support roller.

[0013] In some embodiments, the unwinding spools are configured to be three or more.

[0014] In some embodiments, the unwinding mechanism further includes a first rotary drive assembly, the moving component is mounted on the drive end of the first rotary drive assembly, and each of the unwinding shafts is spaced apart around the rotation axis of the moving component.

[0015] In some embodiments, the unwinding mechanism further includes a plurality of support rollers, all of which are mounted on the moving component and are arranged between every two adjacent unwinding shafts in the rotational direction of the moving component.

[0016] In some embodiments, the unwinding mechanism further includes a first mounting base and at least two second rotary drive assemblies, each of the unwinding shafts being rotatably connected to the moving component and the first mounting base about its own axis;

[0017] Each of the second rotary drive components is mounted on the first mounting base, and the drive end of each of the second rotary drive components is connected to each of the unwinding shafts.

[0018] In some embodiments, the tape changing device further includes a correction mechanism, which includes a correction drive and a connector mounted on the drive end of the correction drive.

[0019] The tape receiving mechanism further includes a second mounting base, on which the first pressing component and the first cutting component are both mounted, and the connecting member is fixedly connected to the second mounting base;

[0020] The connector is movably connected to the first mounting base so that the first mounting base can rotate relative to the connector about the rotation axis of the moving component.

[0021] In some embodiments, the tape changing device further includes an adhesive applicator disposed downstream of the tape splicing mechanism, the connector being connected to the adhesive applicator.

[0022] In some embodiments, the correction drive is used to drive the connector to move along the rotation axis of the moving component.

[0023] In some embodiments, the correction mechanism further includes a first roller and a second roller mounted on the connector, the first roller and the second roller being arranged at a distance from each other, and the peripheral edge of the first mounting base being located between the first roller and the second roller.

[0024] In some embodiments, the tape changing device further includes an adhesive applicator, which includes a roller pressing assembly, an adhesive feeding assembly, and an adhesive cutting assembly. The adhesive feeding assembly is arranged between the downstream of the tape feeding mechanism and the upstream of the roller pressing assembly, and the adhesive cutting assembly is arranged on the side of the roller pressing assembly facing the adhesive feeding assembly.

[0025] In some embodiments, the roller pressing assembly is arranged opposite to the part to be coated, the glue feeding assembly is used to feed the starting end of the passing material strip between the roller pressing assembly and the part to be coated, the roller pressing assembly is used to press the starting end of the material strip against the part to be coated, and the glue cutting assembly is used to cut the passing material strip.

[0026] A winding device includes a strip changing device as described in any of the above embodiments.

[0027] In actual use, the aforementioned strip changing device and winding equipment utilize an unwinding shaft located at the unwinding station to rotate the strip on it, thereby unwinding and outputting the strip downstream. A strip is also loaded onto the unwinding shaft located at the connecting station as a spare.

[0028] When the roll of material on the unwinding shaft at the unwinding station is unwound, firstly, the unwinding shaft at the unwinding station stops unwinding. The first pressing drive drives the first pressure roller to move toward the roll of material on the unwinding shaft at the connecting station until the passing strip is pressed against the roll of material on the unwinding shaft at the connecting station, so that the strip is bonded and fixed to the starting end of the strip on the roll of material on the unwinding shaft at the connecting station. Then, the first cutting drive drives the first cutter to cut the passing strip. At this time, the downstream cut end of the strip is bonded and fixed to the starting end of the strip on the roll of material on the unwinding shaft at the connecting station. The unwinding shaft at the unwinding station drives the roll on it to rotate in the opposite direction until the upstream cut end of the strip is wound up. Then, the first pressing drive drives the first pressure roller to move away from the roll of material on the unwinding shaft at the connecting station and reset, thereby releasing the downstream cut end of the strip. Then, the moving parts drive the unwinding shaft located at the unwinding station away from the unwinding station, and at the same time drive the unwinding shaft located at the connecting station to move to the unwinding station. At this time, the unwinding shaft located at the unwinding station continues to drive the material roll on it to rotate, thereby continuing to unwind and output the material belt downstream; the unwinding shaft located at the connecting station loads a new material roll, waiting for the next roll change and splicing.

[0029] Thus, the tape changing device in this application uses the first pressing component and the first cutting component to connect the tape, and uses the moving parts to drive the unwinding shaft to switch between the connecting station and the unwinding station, thereby realizing automatic tape changing, which greatly improves the degree of automation, reduces the labor intensity of manual labor, and improves production efficiency.

[0042] Please see Figure 1 This application provides a tape changing device, including an unwinding mechanism 20 and a tape receiving mechanism 30. The unwinding mechanism 20 includes a moving part 21 and at least two unwinding shafts 22 disposed on the moving part 21. The moving part 21 can drive each unwinding shaft 22 to pass sequentially through a connecting station a2 and an unwinding station a1. Each unwinding shaft 22 can be loaded with a tape roll. The unwinding shaft 22 located at the unwinding station a1 is used to drive the tape roll on it to rotate and unwind the tape A downstream. The tape roll on the unwinding shaft 22 located at the connecting station a2 serves as a spare tape roll, waiting to be unwound and output downstream when switching from the connecting station a2 to the unwinding station a1.

[0043] A tape-connecting mechanism 30 and an unwinding shaft 22 located at connection station a2 form a tape-connecting channel b through which the feed tape A passes. That is, the feed tape A unwound from the unwinding shaft 22 at unwinding station a1 passes through the tape-connecting channel b between the tape-connecting mechanism 30 and an unwinding shaft 22 located at connection station a2. The tape-connecting mechanism 30 includes a first pressing assembly 31 (see...). Figure 6 ) and the first cutting assembly 32 (see Figure 6 The first pressing assembly 31 includes a first pressing drive 311 and a first pressure roller 312 mounted on the drive end of the first pressing drive 311. The first cutting assembly 32 includes a first cutting drive 321 and a first cutter 322 mounted on the drive end of the first cutting drive 321, and the first cutter 322 is located upstream of the first pressure roller 312. Optionally, the first pressing drive 311 can be a cylinder, and the first cutting drive 321 can also be a cylinder.

[0044] For the above-mentioned tape changing device, please refer to [the relevant documentation] during actual use. Figure 2 The unwinding shaft 22 located at the unwinding station a1 drives the material roll on it to rotate, thereby unwinding and outputting the material strip A downstream. The unwinding shaft 22 located at the connecting station a2 is also loaded with a material roll as a spare.

[0045] Please see Figure 3 When the material roll on the unwinding shaft 22 at unwinding station a1 is unwound, firstly, the unwinding shaft 22 at unwinding station a1 stops unwinding. The first pressing drive 311 drives the first pressure roller 312 to move toward the material roll on the unwinding shaft 22 at connecting station a2 until the passing material strip A is pressed against the material roll on the unwinding shaft 22 at connecting station a2, so that the material strip A is bonded and fixed to the starting end of the material strip on the material roll on the unwinding shaft 22 at connecting station a2. Then, the first cutting drive 321 drives the first cutter 322 to cut the passing material strip A. At this time, the downstream cut end of the material strip A is bonded and fixed to the starting end of the material strip on the material roll on the unwinding shaft 22 at connecting station a2. The unwinding shaft 22 at unwinding station a1 drives the material roll on it to rotate in the opposite direction until the upstream cut end of the material strip A is wound up. Then, the first pressing drive 311 drives the first pressure roller 312 away from the unwinding shaft 22 located at the connecting station a2 and resets, thereby releasing the downstream cut-off end of the strip A. See also... Figure 4 Then, the moving part 21 drives the unwinding shaft 22 located at the unwinding station a1 to leave the unwinding station a1, and at the same time drives the unwinding shaft 22 located at the connecting station a2 to move to the unwinding station a1. At this time, the unwinding shaft 22 located at the unwinding station a1 continues to drive the material roll on it to rotate, thereby continuing to unwind and output the material belt A downstream; the unwinding shaft 22 located at the connecting station a2 is loaded with a new material roll, waiting for the next roll change and splicing.

[0046] Thus, the tape changing device in this application uses the first pressing component 31 and the first cutting component 32 to connect the tape, and uses the moving component 21 to drive the unwinding shaft 22 to switch between the connecting station a2 and the unwinding station a1, thereby realizing automatic tape changing, which greatly improves the degree of automation, reduces the labor intensity of manual labor, and improves production efficiency.

[0047] It should be noted that the material strip A can be an adhesive tape, meaning that one side of the material strip A is adhesive and the other side is non-adhesive. When the material strip A passes through the tape-connecting channel b, its adhesive side faces the roll on the unwinding shaft 22 located at the connecting station a2, and its non-adhesive side faces the tape-connecting mechanism 30. This allows the material strip A to be bonded and fixed to the starting end of the material strip on the roll by its adhesive side when the first pressure roller 312 presses the material strip A against the roll on the unwinding shaft 22 located at the connecting station a2.

[0048] Of course, material strip A is not limited to adhesive tape. In other embodiments, material strip A can also be a material strip without an adhesive side. In embodiments where material strip A is not an adhesive tape, double-sided tape can be pre-attached to the starting end of the material strip on the roll, so that when the first pressure roller 312 presses the passing material strip A against the roll on the unwinding shaft 22 located at the connecting station a2, the starting end of the material strip on the roll can be bonded and fixed to material strip A by the double-sided tape.

[0049] It should also be noted that after the material belt A is cut, two cut ends are formed at the break point. The one located upstream is the upstream cut end, and the one located downstream is the downstream cut end. In this article, upstream and downstream are relative to the conveying path of material belt A. The position where material belt A arrives first is upstream, and the position where material belt A arrives later is downstream.

[0050] Please see Figure 1 and Figure 6 In some embodiments, at least two first pressing components 31 are provided, arranged sequentially from upstream to downstream, and the first pressure roller 312 of each first pressing component 31 is arranged opposite to the roll on the unwinding shaft 22 at the connecting station a2. Thus, during tape splicing, the first pressing drive 311 of each first pressing component 31 drives each first pressure roller 312 to simultaneously press the passing tape A against the roll on the unwinding shaft 22 at the connecting station a2, thereby ensuring that the contact area between the adhesive surface of tape A and the starting end of the tape on the roll is sufficiently large, thus ensuring good adhesion between tape A and the starting end of the tape, and preventing the downstream cut end of tape A from detaching from the starting end of the tape, leading to splicing failure.

[0051] Specifically Figure 6 In the illustrated embodiment, two first pressing components 31 are provided. Of course, in other embodiments, three or more first pressing components 31 may also be provided, as long as the material strip A can be firmly bonded to the starting end of the material strip, and this is not limited here.

[0052] It should be noted that, in some embodiments, the first pressing assembly 31 includes at least two first pressing rollers 312, each of which is mounted on the driving end of the first pressing drive 311, and each roller is arranged opposite to the roll on the unwinding shaft 22 at the connecting station a2. Thus, during tape splicing, the first pressing drive 311 of the first pressing assembly 31 drives each of the first pressing rollers 312 to simultaneously press the passing tape A against the roll on the unwinding shaft 22 at the connecting station a2. This ensures that the contact area between the adhesive surface of tape A and the starting end of the tape on the roll is sufficiently large, thereby ensuring good adhesion between tape A and the starting end of the tape, and preventing subsequent tape splicing failure due to the downstream cut end of tape A detaching from the starting end of the tape.

[0053] Please see Figure 1 , Figure 5 and Figure 6 In embodiments of this application, the unwinding mechanism 20 further includes a support roller 23. The support roller 23 is arranged between the downstream of the unwinding station a1 and the upstream of the connecting station a2, and is located upstream of the first cutter 322. The support roller 23 is used for the passing strip A to be wound around, thereby supporting the passing strip A and preventing the strip A unwound from the unwinding shaft 22 at the unwinding station a1 from contacting the roll on the unwinding shaft 22 at the connecting station a2, i.e., preventing interference between the roll on the unwinding shaft 22 at the connecting station a2 and the passing strip A.

[0054] Furthermore, the unwinding mechanism 20 also includes a first rotary drive assembly 25. A moving component 21 is mounted on the drive end of the first rotary drive assembly 25, enabling the first rotary drive assembly 25 to drive the moving component 21 to rotate about a rotation axis. Each unwinding shaft 22 is spaced apart around the rotation axis of the moving component 21, so that when the first rotary drive assembly 25 drives the moving component 21 to rotate about the rotation axis, it can drive each unwinding shaft 22 to sequentially pass through the connecting station a2 and the unwinding station a1.

[0055] Furthermore, multiple support rollers 23 are provided, all of which are mounted on the moving part 21, and each support roller 23 is arranged between every two adjacent unwinding shafts 22 in the rotation direction of the moving part 21. Thus, when any two adjacent unwinding shafts 22 rotate with the moving part 21 to the connecting station a2 and the unwinding station a1 respectively, the support roller 23 between the two unwinding shafts 22 also reaches the downstream of the unwinding station a1 and the upstream of the connecting station a2, so that the passing material strip A can be wound around it.

[0056] Specifically, the number of unwinding shafts 22 on the moving part 21 can be three or more. Figure 1In the illustrated embodiment, the moving component 21 has four unwinding shafts 22, which are spaced apart around the rotation axis of the moving component 21. The moving component 21 also has four support rollers 23, with one support roller 23 positioned between every two adjacent unwinding shafts 22 along the circumference of the moving component 21. Thus, every 90° rotation of the moving component 21 drives the unwinding shaft 22 located at the connecting station a2 to the unwinding station a1, while simultaneously causing another unwinding shaft 22 to rotate to the connecting station a2.

[0057] Furthermore, the feeding mechanism 30 also includes a second pressing assembly 33, which includes a second pressing drive 331 and a second pressure roller 332 mounted on the drive end of the second pressing drive 331. The second pressure roller 332 and the support roller 23 located downstream of the unwinding station a1 and upstream of the connecting station a2 are arranged opposite to each other, so that a pressure channel through which the feed belt A passes is formed between them. When splicing is required, the first pressing drive 311 drives the first pressure roller 312 to press the passing strip A against the roll on the unwinding shaft 22 located at the connecting station a2. The second pressing drive 331 drives the second pressure roller 332 to press the passing strip A against the corresponding support roller 23. That is, the portion of strip A upstream of the first cutter 322 is pressed against the corresponding support roller 23 by the second pressure roller 332, and the portion downstream of the first cutter 322 is pressed against the corresponding roll by the first pressure roller 312. This ensures that the first cutter 322 can accurately cut the passing strip A, which helps to improve the cutting quality. Optionally, the second pressing drive 331 can be a cylinder.

[0058] In embodiments of this application, the tape changing device further includes a mounting base 10, on which a first rotary drive assembly 25 is mounted. A moving part 21 is mounted on the drive end of the first rotary drive assembly 25, thereby enabling the first rotary drive assembly 25 to drive the moving part 21 to rotate relative to the mounting base 10 about a rotation axis.

[0059] The unwinding mechanism 20 also includes a first mounting base 28 and at least two second rotary drive assemblies 29. Each unwinding shaft 22 is rotatably connected to the moving component 21 and the first mounting base 28 about its own axis. Each second rotary drive assembly 29 is mounted on the first mounting base 28, and the drive end of each second rotary drive assembly 29 is connected to each unwinding shaft 22, so that each second rotary drive assembly 29 can drive each unwinding shaft 22 to rotate relative to the moving component 21 about its own axis. That is, the first rotary drive assembly 25 can drive each unwinding shaft 22 to revolve with the moving component 21, so that each unwinding shaft 22 passes through the connecting station a2 and the unwinding station a1 in sequence. Each second rotary drive assembly 29 can drive each unwinding shaft 22 to rotate, thereby driving the material roll to rotate to achieve unwinding.

[0060] Further, the first rotary drive assembly 25 includes a first support base 251, a first rotary drive component 252, a rotary shaft 253, and a second support base 254. The first support base 251 and the second support base 254 are respectively fixedly connected to opposite sides of the mounting base 10. The rotary shaft 253 passes through the mounting base 10, and both ends of the rotary shaft 253 are rotatably connected to the first support base 251 and the second support base 254, thereby supporting the rotary shaft 253 using the first support base 251 and the second support base 254. The first rotary drive component 252 is mounted on the first support base 251, and the driving end of the first rotary drive component 252 is connected to the rotary shaft 253, enabling the first rotary drive component 252 to drive the rotary shaft 253 to rotate. The moving component 21 is mounted on the rotary shaft 253, enabling the moving component 21 to rotate together with the rotary shaft 253, thereby driving the various unwinding shafts 22 on the moving component 21 to revolve. The first mounting base 28 has clearance holes for the rotating shaft 253 to pass through. Since one end of each unwinding shaft 22 is rotatably connected to the first mounting base 28, the first mounting base 28 also rotates together with the rotating shaft 253. Thus, when it is necessary to drive the unwinding shaft 22 from the connecting station a2 to the unwinding station a1, the first rotary drive 252 drives the rotating shaft 253 to rotate. The rotating shaft 253 then drives the moving part 21, each unwinding shaft 22, the first mounting base 28, and each second rotary drive assembly 29 on the first mounting base 28 to rotate together around the rotation axis until the unwinding shaft 22 located at the connecting station a2 reaches the unwinding station a1.

[0061] Furthermore, the first rotary drive assembly 25 also includes a drive gear 255 and a driven gear 256. The drive gear 255 is mounted on the output shaft of the first rotary drive member 252, thereby enabling the first rotary drive member 252 to drive the drive gear 255 to rotate. The driven gear 256 is mounted on the rotating shaft 253, thereby enabling the driven gear 256 to drive the rotating shaft 253 to rotate together. The drive gear 255 and the driven gear 256 mesh with each other, so that when the first rotary drive member 252 drives the drive gear 255 to rotate, the drive gear 255 drives the driven gear 256 to rotate, and the driven gear 256 then drives the rotating shaft 253 to rotate. Optionally, the first rotary drive member 252 may be a motor.

[0062] Furthermore, each second rotary drive assembly 29 includes a second rotary drive member, a drive pulley, a driven pulley, and a transmission belt. The second rotary drive member is mounted on the first mounting base 28, and the drive pulley is mounted on the output shaft of the second rotary drive member, enabling the second rotary drive member to drive the drive pulley to rotate. The driven pulley is mounted on the corresponding unwinding shaft 22, enabling the driven pulley to drive the unwinding shaft 22 to rotate together. The transmission belt is tensioned between the drive pulley and the driven pulley, enabling the drive pulley to drive the driven pulley to rotate synchronously via the transmission belt. Thus, when the second rotary drive member drives the drive pulley to rotate, the drive pulley drives the driven pulley to rotate via the transmission belt, the driven pulley then drives the unwinding shaft 22 to rotate, and the unwinding shaft 22 then drives the material roll on it to rotate, thereby achieving unwinding. Optionally, the second rotary drive member can be a motor.

[0063] Please see Figures 5 to 8 Specifically, in this embodiment, the tape changing device further includes a web-correcting mechanism 50, which includes a web-correcting drive 51 and a connector 52 mounted on the drive end of the web-correcting drive 51. The web-correcting drive 51 drives the connector 52 to move along the axial direction of the rotation axis 253 (i.e., along the aforementioned rotation axis). The tape-connecting mechanism 30 also includes a second mounting base 34, on which the first pressing assembly 31, the second pressing assembly 33, and the first cutting assembly 32 are all mounted. The connector 52 is fixedly connected to the second mounting base 34, thereby enabling the connector 52 to drive the second mounting base 34 and the first pressing assembly 31, the second pressing assembly 33, and the first cutting assembly 32 on the second mounting base 34 to move together along the axial direction of the rotation axis 253.

[0064] The connector 52 is movably connected to the first mounting base 28 so that the first mounting base 28 can rotate relative to the connector 52 about the axis of the rotation shaft 253 (i.e., the aforementioned rotation axis), thereby enabling the connector 52 to drive the first mounting base 28 to move axially along the rotation shaft 253 without interfering with the rotational movement of the first mounting base 28 following the rotation shaft 253.

[0065] Thus, when it is necessary to correct the deviation of the material strip A, the deviation correction drive 51 drives the connecting part 52 to move axially along the rotating shaft 253, thereby driving each unwinding shaft 22 to move relative to the moving part 21 along the rotating shaft 253 via the first mounting base 28. At the same time, the first pressing assembly 31, the second pressing assembly 33 and the first cutting assembly 32 are driven together to move axially along the rotating shaft 253 via the second mounting base 34. This causes the material roll on the unwinding shaft 22 located at the unwinding station a1 and the unwinding output material strip A to move axially along the rotating shaft 253, thereby realizing the position adjustment of the material strip A along its own width direction (i.e., the axial direction of the unwinding shaft 22).

[0066] Furthermore, the correction mechanism 50 also includes a first correction guide rod 53, a first correction guide sleeve 54, and a first correction seat 55. A first mounting hole is provided on the mounting base 10, and the first correction guide sleeve 54 is installed in the first mounting hole of the mounting base 10. The first correction guide rod 53 passes through the first correction guide sleeve 54, and one end of the first correction guide rod 53 is fixedly connected to the second mounting seat 34, while the other end of the first correction guide rod 53 is fixedly connected to the first correction seat 55. The first correction seat 55 is fixedly connected to the connecting member 52. The correction drive member 51 is mounted on the mounting base 10, and the drive end of the correction drive member 51 is connected to the first correction seat 55, enabling the correction drive member 51 to drive the first correction seat 55 to move axially along the rotation axis 253. Thus, using the first correction guide rod 53 to guide the axial movement of the second mounting seat 34 along the rotation axis 253 helps improve the correction accuracy of the material strip A.

[0067] Specifically, in the embodiment, the correction mechanism 50 also includes first rollers 521, all mounted on the connector 52 (see...). Figure 8 ) and the second roller 522 (see Figure 8 The first roller 521 and the second roller 522 are arranged opposite each other and spaced apart along the axial direction of the rotation shaft 253. The peripheral edge of the first mounting base 28 is located between the first roller 521 and the second roller 522. Thus, when the rotation shaft 253 rotates, it can drive the first mounting base 28 to rotate relative to the connecting member 52, so that the first roller 521 and the second roller 522 roll on opposite side surfaces of the first mounting base 28 respectively, ensuring that the first connecting member 52 does not interfere with the rotational movement of the first mounting base 28 following the rotation shaft 253, and can drive the first mounting base 28 to move along the axial direction of the rotation shaft 253.

[0068] Please see again Figure 1In the embodiments of this application, the tape changing device further includes an adhesive applicator 40, which is arranged downstream of the tape receiving mechanism 30. The adhesive applicator 40 is used to attach the starting end of the passing tape A to the workpiece to be adhesiveled, and to cut the tape A. The cut portion of tape A is the adhesive tape attached to the workpiece, thus achieving the application of adhesive tape to the workpiece. It is understood that in this embodiment, tape A is an adhesive tape.

[0069] It should be noted that the part to be adhesive-coated can be a core B wound on the roller 101. The adhesive application mechanism 40 applies tape to the core B, so that the tail end of the tape on the core B is adhered to the outer surface of the core B through the tape, thereby preventing the core B from becoming loose. Of course, the part to be adhesive-coated can also be other products that require tape application, and this is not limited here. For ease of understanding, this article uses the core B on the roller 101 as an example for illustration.

[0070] Specifically, in this embodiment, the adhesive applicator 40 includes a third mounting base 44 and a roller pressing assembly 42, an adhesive feeding assembly 41, and an adhesive cutting assembly 43, all mounted on the third mounting base 44. The roller pressing assembly 42 and the core B on the winding needle 101 are arranged opposite to each other. The adhesive feeding assembly 41 is arranged between the downstream of the tape receiving mechanism 30 and the upstream of the roller pressing assembly 42, and is used to feed the starting end of the tape A between the roller pressing assembly 42 and the core B on the winding needle 101. The roller pressing assembly 42 is used to press the starting end of the tape A against the core B on the winding needle 101, so that the starting end of the tape A is adhered to the core B. The winding needle 101 can drive the core B on it to rotate, thereby driving a certain length of tape A to be adhered to the core B. The adhesive cutting assembly 43 is arranged on the side of the roller pressing assembly 42 facing the adhesive feeding assembly 41 (i.e., the downstream side of the roller pressing assembly 42), and is used to cut the passing tape A, so that the starting end of the tape A is cut off to form an adhesive tape.

[0071] Thus, in actual use, when it is necessary to apply adhesive to the core B on the needle 101, firstly, the adhesive feeding assembly 41 pulls the tape A toward the needle 101 until the starting end of the tape A is inserted between the core B on the needle 101 and the roller pressing assembly 42; then, the roller pressing assembly 42 presses the starting end of the tape A against the core B of the needle 101; then, the adhesive cutting assembly 43 cuts the tape A, and the cut part of the tape A is the adhesive tape. One end of the adhesive tape is pressed against the core B by the roller pressing assembly 42, and the other end is suspended; then, the needle 101 drives the core B to rotate until the adhesive tape is completely adhered to the core B.

[0072] In a specific embodiment, the glue feeding assembly 41 includes a glue feeding drive unit 411 and a glue clamping unit 412. The glue feeding drive unit 411 is mounted on the third mounting base 44. The glue clamping unit 412 is used to clamp or release the passing material strip A. The glue clamping unit 412 is mounted on the drive end of the glue feeding drive unit 411, so that the glue feeding drive unit 411 can drive the glue clamping unit 412 to move closer to or away from the core B on the winding needle 101. Thus, when the glue clamping unit 412 clamps the passing material strip A, the glue feeding drive unit 411 drives the glue clamping unit 412 to move towards the core B on the winding needle 101 until the starting end of the material strip A is inserted between the roller pressing assembly 42 and the core B on the winding needle 101, thereby realizing the glue feeding action.

[0073] It should be noted that the glue feeding drive unit 411 can be a linear drive module such as an electric cylinder or a pneumatic cylinder, as long as it can feed the starting end of the strip A between the roller pressing assembly 42 and the core B on the winding needle 101, and there is no limitation here. The glue clamping unit 412 can adopt relatively mature existing technologies, such as a gripper mechanism, as long as it can clamp or release the strip A in the path, and there is no limitation here.

[0074] In this embodiment, the roll forming assembly 42 includes a roll forming drive 421 and a pressure roller 423. The roll forming drive 421 is mounted on a third mounting base 44. The pressure roller 423 is mounted on the drive end of the roll forming drive 421, enabling the roll forming drive 421 to drive the pressure roller 423 to move closer to or further away from the core B on the spinning needle 101, thereby pressing the passing strip A onto or separating it from the core B. Optionally, the roll forming drive 421 may be a cylinder.

[0075] In a specific embodiment, the cutting assembly 43 includes a second cutting drive 431 and a second cutter 433. The second cutting drive 431 is mounted on a third mounting base 44. The second cutter 433 is mounted on the drive end of the second cutting drive 431, enabling the second cutting drive 431 to drive the second cutter 433 to cut the passing strip A. Optionally, the second cutting drive 431 can be a cylinder.

[0076] In a specific embodiment, the adhesive applicator 40 further includes a buffer component 45. This buffer component 45 is positioned downstream of the tape receiving component 30 and upstream of the adhesive feeding component 41, and is used to buffer the passing tape A. Thus, when the adhesive feeding component 41 pulls the tape A towards the spacer core B on the needle 101 and the pressure roller 423 of the roller pressing component 42, the buffer component 45 can release the tape A, preventing it from breaking. It should be noted that the buffer component 45 can employ readily available, mature technology, as long as it effectively buffers the tape A; no specific limitations are imposed here.

[0077] Please see again Figure 1 and Figure 7 Specifically, in the embodiment, the third mounting base 44 is fixedly connected to the aforementioned connector 52, so that when the correction drive 51 drives the connector 52 to move axially along the rotating shaft 253, it can drive each unwinding shaft 22 to move axially along the rotating shaft 253 through the first mounting base 28, and at the same time drive the tape receiving mechanism 30 to move axially along the rotating shaft 253 through the second mounting base 34, and drive the adhesive applicator 40 to move axially along the rotating shaft 253 through the third mounting base 44, thereby realizing the position adjustment (i.e., correction) of the tape A, and ensuring that the adhesive applicator 40 can accurately stick the tape to the core B of the winding needle 101.

[0078] Furthermore, the correction mechanism 50 also includes a second correction guide rod 56, a second correction guide sleeve 57, and a second correction seat 58. A second mounting hole is provided on the mounting base 10, and the second correction guide sleeve 57 is installed in the second mounting hole of the mounting base 10. The second correction guide rod 56 passes through the second correction guide sleeve 57, and one end of the second correction guide rod 56 is fixedly connected to the third mounting seat 44, while the other end of the second correction guide rod 56 is fixedly connected to the second correction seat 58. The second correction seat 58 is fixedly connected to the connecting member 52. The driving end of the correction drive member 51 is connected to either the first correction seat 55 or the second correction seat 58, enabling the correction drive member 51 to drive the first correction seat 55 and the second correction seat 58 to move synchronously along the axial direction of the rotation axis 253. Thus, using the second correction guide rod 56 to guide the axial movement of the third mounting seat 44 along the rotation axis 253 helps improve the correction accuracy of the material strip A. It should be noted that the correction drive 51 can be a linear drive module such as an electric cylinder, as long as it can drive the first correction seat 55, the second correction seat 58 and the first mounting seat 28 to move axially along the rotation axis 253, thereby correcting the material strip A. No limitation is made here.
