Description

Technical Field

[0001] This application relates to the field of battery processing equipment technology, and in particular to an adhesive application mechanism, an automatic roll changing device, and a winding device. Background Technology

[0002] A winding machine is a device that uses rotating needles to wind electrode sheets and other materials onto the winding needles to create battery cells. To ensure continuous winding and cell production, winding machines typically include a working roll and a spare roll. First, the working roll supplies material to the winding needles. When the working roll is nearly depleted, the end of the working roll is attached to the beginning of the spare roll using adhesive tape, completing the tape connection. This allows the spare roll to continue supplying material to the winding needles.

[0003] However, when bonding the end of the working material strip to the beginning of the spare material strip, manual glue preparation is required, which is labor-intensive and has low splicing efficiency. Utility Model Content

[0004] This application discloses an adhesive applicator, an automatic roll changing device, and a winding equipment, which can improve tape splicing efficiency while reducing the labor intensity of personnel.

[0005] To achieve the above objectives, in a first aspect, this application discloses an adhesive application mechanism, comprising:

[0006] Installation components;

[0007] A tape-attaching mechanism, disposed on the mounting member, the tape-attaching mechanism including a first adhesive application component and a second adhesive application component; and...

[0008] The adhesive preparation assembly includes an adhesive handling module, which includes an adhesive handling drive module, a first adhesive handling module, and a second adhesive handling module. The adhesive handling drive module is used to drive the first adhesive handling module to pull out a first piece of adhesive tape, and the adhesive handling drive module is also used to drive the second adhesive handling module to pull out a second piece of adhesive tape. The adhesive preparation assembly is used to provide a first piece of adhesive tape to the first adhesive application assembly and a second piece of adhesive tape to the second adhesive application assembly.

[0009] In addition to the first adhesive application component being able to attach the first tape to the tail end of the first strip and the beginning end of the second strip, the second adhesive application component can also attach the second tape to the tail end of the first strip and the beginning end of the second strip. That is, the tail end of the first strip and the beginning end of the second strip can be double-bonded by the first tape and the second tape, thus making the bond more secure.

[0010] Furthermore, since the adhesive transfer drive module can drive the first adhesive transfer module to pull out a section of the first adhesive tape, and the adhesive transfer drive module can also drive the second adhesive transfer module to pull out a section of the second adhesive tape, that is, the same adhesive transfer drive module can drive the first adhesive transfer module and the second adhesive transfer module to pull out a section of the first adhesive tape and a section of the second adhesive tape respectively, there is no need to set up separate adhesive transfer drive modules for the first adhesive transfer module and the second adhesive transfer module. Therefore, on the one hand, the number of adhesive transfer drive modules can be reduced, reducing the cost of the entire adhesive applicator. On the other hand, the entire adhesive applicator can also be made more compact and small.

[0011] In addition, since the same glue handling drive module can drive the first glue handling module and the second glue handling module to pull out a section of the first tape and a section of the second tape respectively, it can provide a section of the first tape to the first adhesive assembly and a section of the second tape to the second adhesive assembly at the same time. This achieves automatic glue preparation for the first adhesive assembly and the second adhesive assembly at the same time. Compared with the method of manually preparing glue for the first adhesive assembly and the second adhesive assembly one by one, it can reduce the labor intensity of personnel, improve glue preparation efficiency, and thus improve tape splicing efficiency.

[0012] Optionally, it also includes:

[0013] A first adhesive-prepared mounting component is disposed on the mounting component;

[0014] A first adhesive supply module is disposed on the first adhesive preparation mounting component and corresponding to the first adhesive application component, and is used to provide a section of the first adhesive tape.

[0015] The second adhesive-prepared mounting component is disposed on the mounting component;

[0016] The second adhesive supply module is disposed on the second adhesive preparation mounting component and is correspondingly disposed to the second adhesive application component, and is used to provide a section of the second adhesive tape.

[0017] The first adhesive transfer module is used to pull out a section of the first adhesive tape from the first adhesive supply module, and the second adhesive transfer module is used to pull out a section of the second adhesive tape from the second adhesive supply module.

[0018] Since the first glue supply module is used to provide a section of first tape for the first glue handling module to pull out from the first glue supply module, and the second glue supply module is used to provide a section of second tape for the second glue handling module to pull out from the second glue handling module, in this way, the first glue handling module and the second glue handling module can each have an independent glue supply module, thereby avoiding the situation where the first glue handling module and the second glue handling module interfere with each other when pulling glue.

[0019] Optionally, the first adhesive mounting component and the second adhesive mounting component are spaced apart to form a gap, and the first adhesive application component and the second adhesive application component are located within the gap.

[0020] By positioning the first adhesive application assembly and the second adhesive application assembly within the gap, the first adhesive application assembly and the second adhesive application assembly can make full use of the gap between the first adhesive preparation mounting component and the second adhesive preparation mounting component, making the structure of the entire adhesive application mechanism more compact.

[0021] On the other hand, from the perspective of structural layout, it is convenient for a section of the first tape on the first glue supply module to be transported to the first adhesive application component, and it is also convenient for a section of the second tape on the second glue supply module to be transported to the second adhesive application component.

[0022] Optionally, the glue-moving drive module is disposed on the mounting component, the first glue-moving module is slidably disposed on the first glue-preparing mounting component and connected to the glue-moving drive module, and the second glue-moving module is slidably disposed on the second glue-preparing mounting component and connected to the glue-moving drive module.

[0023] The adhesive transfer drive module is used to drive the first adhesive transfer module and the second adhesive transfer module to slide synchronously, so that the first adhesive transfer module pulls out a section of the first adhesive tape from the first adhesive supply module and the second adhesive transfer module pulls out a section of the second adhesive tape from the second adhesive supply module.

[0024] Since the first glue-handling module is slidably mounted on the first glue-preparing mounting component and connected to the glue-handling drive module, and the second glue-handling module is slidably mounted on the second glue-preparing mounting component and connected to the glue-handling drive module, when the glue-handling drive module drives the first and second glue-handling modules to move, the movement of the first and second glue-handling modules can be made more stable under the guidance of the first and second glue-preparing mounting components.

[0025] Optionally, both the first adhesive transfer module and the second adhesive transfer module are located on the first side of the mounting component, and at least a portion of the adhesive transfer drive module is located on the second side of the mounting component opposite to the first side.

[0026] This configuration allows the first and second adhesive transfer modules, along with the adhesive transfer drive module, to be located on opposite sides of the mounting component. This makes full use of the space on both sides of the mounting component, resulting in a more compact and smaller adhesive application mechanism.

[0027] Optionally, the glue transfer drive module includes:

[0028] A support, the support being disposed on the mounting member and located on the second side of the mounting member;

[0029] A glue-moving drive unit, wherein the glue-moving drive unit is disposed on the support;

[0030] A first connecting rod, wherein the first connecting rod is slidably disposed through the mounting member and one end located on the second side is connected to the adhesive transfer drive member, and the other end located on the first side is connected to the first adhesive transfer module; and

[0031] The second link is slidably inserted through the mounting component and has one end on the second side connected to the glue-handling drive component and the other end on the first side connected to the second glue-handling module.

[0032] Since the first connecting rod is slidably inserted through the mounting component and its second end is connected to the glue-handling drive component and its first end is connected to the first glue-handling module, and the second connecting rod is slidably inserted through the mounting component and its second end is connected to the glue-handling drive component and its first end is connected to the second glue-handling module, when the glue-handling drive component drives the first connecting rod and the second connecting rod to slide synchronously, the purpose of synchronously driving the first glue-handling module and the second glue-handling module to slide can be achieved.

[0033] It is evident that the first and second glue-handling modules can be synchronously driven to slide using the same glue-handling drive component, eliminating the need for separate glue-handling drive components for each module. Therefore, on the one hand, this makes the overall glue-handling module structure more compact, and on the other hand, it reduces the number of glue-handling drive components and lowers the cost of the glue-handling module.

[0034] Optionally, the first glue transfer module includes:

[0035] A first movable component is slidably disposed on the first glue-preparing mounting component along a first direction and connected to the glue-handling drive module;

[0036] A rubber-pulling roller drive unit, wherein the rubber-pulling roller drive unit is disposed on the first movable member;

[0037] A glue-applying roller mounting component is connected to a glue-applying roller driving component, which is used to drive the glue-applying roller mounting component to move closer to or away from the first adhesive application assembly along a second direction.

[0038] A glue-pulling roller is rotatably mounted on a glue-pulling roller mounting component. The glue-pulling roller is used to adhere the first tape to itself when rotating. The glue-handling drive module is used to drive the first moving component to slide along the first direction so that the glue-pulling roller pulls out a section of the first tape from the first glue supply module. The glue-pulling roller is also used to flatten the first tape adhered to itself onto the first adhesive application component when rotating.

[0039] When a section of first tape needs to be placed on the first adhesive application assembly via the first adhesive transfer module, with the adhesive pull roller positioned directly above the first tape, firstly, the adhesive pull roller drive unit can drive the adhesive pull roller mounting unit to move closer to the first adhesive application assembly along the second direction, so that the adhesive pull roller moves to abut against the adhesive surface of the first tape. Then, the adhesive transfer drive module can drive the first moving component to slide in the positive direction of the first direction, causing the adhesive pull roller to move in the positive direction of the first direction, so that the adhesive pull roller rotates counterclockwise relative to the first tape and the first tape is adhered to the adhesive pull roller.

[0040] Next, the glue-handling drive module can drive the first moving part to slide in the negative direction of the first direction, so that the glue-pulling roller pulls out a section of the first adhesive tape from the first glue supply module. This section of the first adhesive tape can be positioned just above the first adhesive application component. Furthermore, the glue-pulling roller can rotate clockwise relative to the first adhesive tape so that the adhesive tape adhered to itself is flattened on the first adhesive application component.

[0041] As can be seen, the adhesive roller can cleverly utilize the adhesive properties of the first adhesive tape to pick it up, and pull out a section of the first adhesive tape from the first adhesive supply module during the negative movement of the adhesive roller along the first direction. This eliminates the need for grippers to pick up the first adhesive tape, thus simplifying the structure of the first adhesive handling module and reducing its cost. Furthermore, it eliminates the need to reserve space for the opening and closing of the grippers, making the entire first adhesive handling module more compact. It also eliminates the need to consider interference between the grippers and the first adhesive application component during the opening and closing process. Moreover, the first adhesive tape does not need to protrude beyond the edge of the first adhesive application component for gripper gripping, allowing the first adhesive tape to be completely placed on the first adhesive application component, resulting in more stable placement of the first adhesive tape on the component.

[0042] Optionally, the adhesive preparation assembly further includes:

[0043] The first tape cutter is used to cut the first tape so that a section of the first tape is detached from the first adhesive supply module.

[0044] By setting up the first tape cutting component, a section of the first tape can be detached from the first adhesive supply module by cutting, thus preparing for the subsequent application of the first tape to the material belt by the first adhesive application component.

[0045] Optionally, the adhesive preparation assembly further includes:

[0046] A first tape clamping assembly is located downstream of the first adhesive supply module along the conveying path of the first tape, and the tape clamping assembly is used to clamp or release the first tape.

[0047] Since the first tape clamping assembly is located downstream of the first adhesive supply module along the conveying path of the first tape, it can clamp the first tape when the first tape cutter needs to cut it, ensuring accurate and stable cutting. When a section of the first tape needs to be pulled out from the first adhesive supply module by the pull roller, the first tape clamping assembly can release the first tape, ensuring the pull roller can pull out a section of the first tape from the first adhesive supply module.

[0048] Optionally, the first tape clamping assembly includes:

[0049] First clamping component;

[0050] The second clamping member, wherein the first clamping member is movable in a direction toward or away from the second clamping member, to clamp or release the first tape;

[0051] A pusher is fixedly disposed and is used to recess or protrude from the clamping surface of the first clamping member when the first clamping member moves in a direction close to or away from the second clamping member.

[0052] With this configuration, when the first tape is attached to the first clamping member, the pushing member can protrude from the clamping surface of the first clamping member, which can push the first tape and thus peel the first tape off the first clamping member.

[0053] Optionally, the first adhesive application assembly includes:

[0054] The first adsorption element is used to adsorb or release a section of the first tape.

[0055] The second adsorption element is used to adsorb or release the material strip, and the first adsorption element is also used to attach a section of the first tape to the material strip.

[0056] Since the first adsorption element can adsorb or release a section of the first tape, when the first adsorption element adsorbs a section of the first tape, it can achieve the purpose of placing a section of the first tape stably in the first adhesive assembly.

[0057] Optionally, the first adhesive application assembly further includes:

[0058] A flipping drive module is disposed on the mounting component and is used to drive the first adhesive component to flip so that the first adsorption component faces the material strip or the second adsorption component faces the material strip.

[0059] Since the flip drive module can drive the first adhesive application component to flip, and can make the first adsorption component face the material strip or the second adsorption component face the material strip, when it is necessary to adsorb the material strip by the second adsorption component, the flip drive module can drive the first adhesive application component to flip, so that the second adsorption component faces the material strip and is in the adsorption state of the material strip. This makes it easier for the second adsorption component to adsorb the material strip.

[0060] When it is necessary to attach a section of the first tape to the material belt through the first adsorption component, the flipping drive module can drive the first adhesive application component to flip so that the first adsorption component faces the material belt and is in the adhesive application state. This makes it easier for the first adsorption component to attach a section of the first tape to the material belt.

[0061] As can be seen, by driving the first adhesive application component to flip through the flipping drive module, the first adhesive application component can switch between the state of adsorbing material strip and the state of applying adhesive, which is very flexible.

[0062] Optionally, the first adhesive application assembly further includes:

[0063] A motion drive module is disposed on the mounting component and is used to drive the first adhesive application component to move toward or away from the second adhesive application component.

[0064] When the moving drive module drives the first adhesive application component to move closer to or further away from the second adhesive application component, the tape can be clamped between the first adhesive application component and the second adhesive application component, thereby achieving the purpose of tape splicing.

[0065] Secondly, this application discloses an automatic roll changing device, comprising:

[0066] A first unwinding shaft is used to load a first roll of material, and the first roll of material is used to unwind a first strip of material through the tape receiving mechanism.

[0067] A second unwinding shaft, used to load a second roll of material, used to unwind a second strip of material through the tape-receiving mechanism; and...

[0068] The adhesive application mechanism described in any of the first aspects above;

[0069] The first adhesive application assembly is used to attach a section of the first adhesive tape to the tail end of the first strip and the starting end of the second strip, wherein the first adhesive tape is located on a first side of the strip; the second adhesive application assembly is used to attach the second adhesive tape to the tail end of the first strip and the starting end of the second strip, wherein the second adhesive tape is located on a second side of the strip opposite to the first side.

[0070] Optionally, the automatic roll changing device further includes:

[0071] A take-up roller assembly, located downstream of the tape receiving mechanism, includes a first take-up roller and a second take-up roller, both of which are rotatably arranged. The first take-up roller is used to wind up the first tape, and the second take-up roller is used to wind up the second tape.

[0072] By setting a second take-up roller, while the winding equipment is winding the first strip, the second strip on the second unwinding shaft can be pre-positioned on the second take-up roller. This prepares for the subsequent cutting of the second strip to generate the starting end for splicing.

[0073] Optionally, at least one of the first take-up roller and the second take-up roller may be movably disposed on the mounting member along the axial direction of the first take-up roller.

[0074] When the first and second strips are misaligned, the first and second strips can be realigned by moving at least one of the first and second take-up rollers along the axial direction of the first take-up roller, thereby improving the splicing effect.

[0075] Optionally, the take-up roller assembly further includes:

[0076] A take-up roller support, wherein the take-up roller support is disposed on the mounting component;

[0077] A take-up roller moving member, wherein both the first take-up roller and the second take-up roller are rotatably mounted on the take-up roller moving member; and...

[0078] A take-up roller moving drive is disposed on the take-up roller support and is used to drive the take-up roller moving component to move along the axial direction of the first take-up roller.

[0079] Since both the first and second take-up rollers can be rotatably mounted on the take-up roller moving component, when the take-up roller moving drive component drives the take-up roller moving component to move along the axial direction of the first take-up roller, it can simultaneously drive the first and second take-up rollers to move along the axial direction of the first take-up roller. That is, the same take-up roller moving drive component can simultaneously drive the first and second take-up rollers to move along the axial direction of the first take-up roller, eliminating the need to set up separate take-up roller moving drive components for the second take-up roller along the first take-up roller, thereby achieving the goal of reducing the cost of the automatic roll changing device.

[0080] Optionally, the take-up roller assembly further includes:

[0081] A take-up roller rotation drive, wherein the take-up roller rotation drive is disposed on the take-up roller moving member; and...

[0082] A pulley structure is provided, wherein the pulley structure is respectively connected to the first take-up roller and the second take-up roller for transmission.

[0083] The take-up roller rotation drive is used to synchronously drive the first take-up roller and the second take-up roller to rotate via the pulley structure.

[0084] Since the pulley structure is connected to the first take-up roller and the second take-up roller respectively, when the take-up roller rotation drive starts to rotate either the first take-up roller or the second take-up roller, the pulley structure can synchronously transmit the rotation to the other. That is, under the action of the pulley structure, the same take-up roller rotation drive can synchronously drive the first take-up roller and the second take-up roller to rotate, without the need to set up independent take-up roller rotation drives for the first take-up roller and the second take-up roller respectively. This can reduce the number of take-up roller rotation drives and reduce the cost of the automatic roll changing device.

[0085] Optionally, it also includes:

[0086] A first offset detection component is used to detect the offset of the first strip along the axial direction of the first take-up roller.

[0087] By setting up a first offset detection component, the offset of the first strip along the axial direction of the first take-up roller can be automatically detected, making the automatic roll changing device more intelligent and more automated.

[0088] Optionally, the first offset detection component includes:

[0089] Sensor mounting base;

[0090] A first sensor is disposed on the sensor mounting base;

[0091] The second sensor is disposed on the sensor mounting base. The detection ends of the first sensor and the second sensor are spaced apart and opposite to each other to form a detection slot through which the first material belt passes. The sensor mounting base is provided with an air blowing hole for blowing air toward the detection ends of the first sensor and / or the second sensor.

[0092] By providing an air blowing hole on the sensor mounting base and blowing air towards the detection end of the first sensor and / or the detection end of the second sensor, dust on the detection end of the first sensor and / or the detection end of the second sensor can be blown away in a timely manner, thereby improving the detection accuracy of the first offset detection component.

[0093] Thirdly, this application discloses a winding device, including the automatic winding device described in any one of the second aspects above.

[0094] Compared with the prior art, the beneficial effects of this application are as follows:

[0095] In this application, in addition to the first adhesive component being able to attach the first tape to the tail end of the first strip and the beginning end of the second strip, the second adhesive component can also attach the second tape to the tail end of the first strip and the beginning end of the second strip. That is, the tail end of the first strip and the beginning end of the second strip can be double-bonded by the first tape and the second tape, thus the bonding is more reliable.

[0096] Furthermore, since the adhesive transfer drive module can drive the first adhesive transfer module to pull out a section of the first adhesive tape, and the adhesive transfer drive module can also drive the second adhesive transfer module to pull out a section of the second adhesive tape, that is, the same adhesive transfer drive module can drive the first adhesive transfer module and the second adhesive transfer module to pull out a section of the first adhesive tape and a section of the second adhesive tape respectively, there is no need to set up separate adhesive transfer drive modules for the first adhesive transfer module and the second adhesive transfer module. Therefore, on the one hand, the number of adhesive transfer drive modules can be reduced, reducing the cost of the entire adhesive applicator. On the other hand, the entire adhesive applicator can also be made more compact and small.

[0097] In addition, since the same glue handling drive module can drive the first glue handling module and the second glue handling module to pull out a section of the first tape and a section of the second tape respectively, it can provide a section of the first tape to the first adhesive assembly and a section of the second tape to the second adhesive assembly at the same time. This achieves automatic glue preparation for the first adhesive assembly and the second adhesive assembly at the same time. Compared with the method of manually preparing glue for the first adhesive assembly and the second adhesive assembly one by one, it can reduce the labor intensity of personnel, improve glue preparation efficiency, and thus improve tape splicing efficiency.

[0123] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0124] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0125] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0126] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0127] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0128] Before explaining the technical solution of this application, the background technology of this application shall be explained first.

[0129] A winding machine is a device that uses rotating needles to wind electrode sheets and other materials onto the winding needles to create battery cells. To ensure continuous winding and cell production, winding machines typically include a working roll and a spare roll. First, the working roll supplies material to the winding needles. When the working roll is nearly depleted, the end of the working roll is attached to the beginning of the spare roll using adhesive tape, completing the tape connection. This allows the spare roll to continue supplying material to the winding needles.

[0130] However, when bonding the end of the working material strip to the beginning of the spare material strip, manual glue preparation is required, which is labor-intensive and inefficient. Therefore, this application provides an adhesive application mechanism 100 to solve the above problems.

[0131] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0132] Figure 1 This is a schematic diagram of the structure of an adhesive applicator 100 according to an embodiment of this application. Figure 2 yes Figure 1 Left view of the adhesive applicator 100 Figure 3 yes Figure 1 A schematic diagram of the adhesive applicator 100 from another perspective (some mounting parts 1 are omitted).

[0133] See Figure 1 , Figure 2 and Figure 3 The adhesive applicator 100 includes an installation component 1, a tape receiving mechanism 2, and an adhesive preparation component 3. The tape receiving mechanism 2 is disposed on the installation component 1 and includes a first adhesive applicator component 21 and a second adhesive applicator component 22.

[0134] Figure 4 yes Figure 2 A schematic diagram of the structure of the adhesive applicator 100 when applied to the automatic roll changer 200. Figure 5 yes Figure 3 A simplified schematic diagram of the connecting mechanism 2 along the negative Z-axis.

[0135] See Figure 3 , Figure 4 and Figure 5 The adhesive preparation component 3 is disposed on the mounting component 1 and is used to provide a section of first adhesive tape J1 to the first adhesive application component 21 and a section of second adhesive tape J2 to the second adhesive application component 22. The first adhesive application component 21 and the second adhesive application component 22 are used to respectively adhere a section of first adhesive tape J1 and a section of second adhesive tape J2 to the material tape L.

[0136] In this embodiment, when the tail end of the first material strip L1 is bonded to the starting end of the second material strip L2 by the adhesive applicator 100, firstly, a section of first adhesive tape J1 is provided to the first adhesive applicator 21 and a section of second adhesive tape J2 is provided to the second adhesive applicator 22 by the adhesive preparation component 3. Then, the first adhesive applicator 21 and the second adhesive applicator 22 can respectively adhere the section of first adhesive tape J1 and the section of second adhesive tape J2 to the material strip L. Specifically, the first adhesive applicator 21 can adhere the first adhesive tape J1 to the tail end of the first material strip L1 and the starting end of the second material strip L2, and the second adhesive applicator 22 can adhere the second adhesive tape J2 to the tail end of the first material strip L1 and the starting end of the second material strip L2. In this way, the purpose of bonding the tail end of the first material strip L1 to the starting end of the second material strip L2 can be achieved, that is, the purpose of splicing the strips can be achieved.

[0137] In addition to the first adhesive component 21 being able to attach the first tape J1 to the tail end of the first material strip L1 and the beginning end of the second material strip, the second adhesive component 22 is also able to attach the second tape J2 to the tail end of the first material strip L1 and the beginning end of the second material strip. That is, the tail end of the first material strip L1 and the beginning end of the second material strip L2 can be double-bonded by the first tape J1 and the second tape J2, thus making the bond more secure.

[0138] In some embodiments, see Figure 3 and Figure 6 The glue preparation component 3 includes a glue handling module 35, which includes a glue handling drive module 351, a first glue handling module 352, and a second glue handling module 353. The glue handling drive module 351 is used to drive the first glue handling module 352 to pull out a first piece of adhesive tape J1, and the glue handling drive module 351 is also used to drive the second glue handling module 353 to pull out a second piece of adhesive tape J2.

[0139] Since the adhesive transfer drive module 351 can drive the first adhesive transfer module 352 to pull out a section of the first adhesive tape J1, and the adhesive transfer drive module 351 can also drive the second adhesive transfer module 353 to pull out a section of the second adhesive tape J2, that is, the same adhesive transfer drive module 351 can drive the first adhesive transfer module 352 and the second adhesive transfer module 353 to pull out a section of the first adhesive tape J1 and a section of the second adhesive tape J2 respectively, there is no need to set up independent adhesive transfer drive modules 351 for the first adhesive transfer module 352 and the second adhesive transfer module 353. Therefore, on the one hand, the number of adhesive transfer drive modules 351 can be saved, reducing the cost of the entire adhesive applicator 100. On the other hand, the entire adhesive applicator 100 can also be made more compact and small.

[0140] In addition, since the same glue handling drive module 351 can drive the first glue handling module 352 and the second glue handling module 353 to pull out a first tape J1 and a second tape J2 respectively, a first tape J1 can be provided to the first adhesive assembly 21 and a second tape J2 can be provided to the second adhesive assembly 22 at one time. This achieves automatic glue preparation for the first adhesive assembly 21 and the second adhesive assembly 22 at one time. Compared with the method of manually preparing glue for the first adhesive assembly 21 and the second adhesive assembly 22 one by one, it can reduce the labor intensity of personnel, improve glue preparation efficiency, and thus improve tape splicing efficiency.

[0141] It should be noted that the aforementioned mounting component 1 can be a plate-like structure or any other possible structure, and this embodiment does not limit it. The aforementioned strip L can be an electrode sheet, etc., and this embodiment does not limit it.

[0142] The first material belt L1 mentioned above can be understood as the working material belt, and the second material belt L2 can be understood as the spare material belt.

[0143] It should also be noted that there are multiple ways to implement the aforementioned adhesive preparation component 3. In one possible implementation, see [link to relevant documentation]. Figure 3 and Figure 6 , Figure 6 yes Figure 3 A schematic diagram of the structure of the glue preparation assembly 3 from another perspective (omitting the mounting component 1 and other parts of the structure). The glue preparation assembly 3 also includes a first glue preparation mounting component 31, a first glue supply module 32, a second glue preparation mounting component 33, a second glue supply module 34, and a glue handling module 35. The first glue preparation mounting component 31 is disposed on the mounting component 1, and the first glue supply module 32 is disposed on the first glue preparation mounting component 31 and is correspondingly disposed with the first adhesive application assembly 21, for providing a section of first adhesive tape J1.

[0144] The second adhesive preparation mounting component 33 is disposed on the mounting component 1, and the second adhesive supply module 34 is disposed on the second adhesive preparation mounting component 33 and is correspondingly disposed with the second adhesive application component 22. It is used to provide a section of second adhesive tape J2. The first adhesive handling module 352 is used to pull out a section of first adhesive tape J1 from the first adhesive supply module 32, and the second adhesive handling module 353 is used to pull out a section of second adhesive tape J2 from the second adhesive supply module 34.

[0145] Since the first glue supply module 32 is used to provide a first tape J1 for the first glue handling module 352 to pull out from the first glue supply module 32, and the second glue supply module 34 is used to provide a second tape J2 for the second glue handling module 353 to pull out from the second glue handling module 353, in this way, the first glue handling module 352 and the second glue handling module 353 can each have an independent glue supply module, thereby avoiding the situation where the first glue handling module 352 and the second glue handling module 353 interfere with each other when pulling glue.

[0146] The first adhesive-prepared mounting component 31 and the second adhesive-prepared mounting component 33 can both be plate-shaped structures. When the first adhesive-prepared mounting component 31, the second adhesive-prepared mounting component 33, and the mounting component 1 are all plate-shaped structures, see [reference to previous text] for some possible implementations. Figure 3 The surfaces of the first adhesive-prepared mounting component 31 and the second adhesive-prepared mounting component 33 can be arranged at intervals relative to each other, and the surfaces of the first adhesive-prepared mounting component 31 and the second adhesive-prepared mounting component 33 are perpendicular to the surface of the mounting component 1, respectively.

[0147] Of course, the first adhesive mounting component 31 and the second adhesive mounting component 33 can also be other possible structures, and this embodiment does not limit them.

[0148] It should be noted that, see Figure 3The first glue supply module 32 and the second glue supply module 34 can be roller-shaped structures. The first glue supply module 32 can be wound with a first tape J1 and the second glue supply module 34 can be wound with a second tape J2. In this way, when the first glue supply module 32 rotates, it can provide a section of the first tape J1 to the glue transfer module 35, and when the first glue supply module 32 rotates, it can provide a section of the second tape J2 to the glue transfer module 35.

[0149] In some embodiments, see Figure 3 The first adhesive mounting component 31 and the second adhesive mounting component 33 are arranged opposite each other to form a gap, and the first adhesive application component 21 and the second adhesive application component 22 are located within the gap.

[0150] By positioning the first adhesive application component 21 and the second adhesive application component 22 within the gap, the first adhesive application component 21 and the second adhesive application component 22 can fully utilize the gap between the first adhesive preparation mounting component 31 and the second adhesive preparation mounting component 33, making the structure of the entire adhesive application mechanism 100 more compact.

[0151] On the other hand, from the perspective of structural layout, it is convenient for a section of the first tape J1 on the first glue supply module 32 to be transported to the first adhesive application component 21, and it is also convenient for a section of the second tape J2 on the second glue supply module 34 to be transported to the second adhesive application component 22.

[0152] In some embodiments, see Figure 3 and Figure 6 The glue-handling drive module 351 is mounted on the mounting component 1, and the first glue-handling module 352 is slidably mounted on it. Figure 3 The first glue preparation mounting component 31 (in the X-axis direction) is set on the first glue preparation mounting component 31 and connected to the glue handling drive module 351, and the second glue handling module 353 is slidably set on the second glue preparation mounting component 33 and connected to the glue handling drive module 351.

[0153] The glue transfer drive module 351 is used to drive the first glue transfer module 352 and the second glue transfer module 353 to slide synchronously, so that the first glue transfer module 352 transfers a section of the first tape J1 from the first glue supply module 32 and the second glue transfer module 353 transfers a section of the second tape J2 from the second glue supply module 34.

[0154] Since the first adhesive transfer module 352 is slidably disposed on the first adhesive preparation mounting component 31 and connected to the adhesive transfer drive module 351, and the second adhesive transfer module 353 is slidably disposed on the second adhesive preparation mounting component 33 and connected to the adhesive transfer drive module 351, the adhesive transfer drive module 351 can synchronously drive the first adhesive transfer module 352 and the second adhesive transfer module 353 to slide. This achieves the goal of the first adhesive transfer module 352 moving a section of the first adhesive tape J1 from the first adhesive supply module 32 to the first adhesive application component 21, while the second adhesive transfer module 353 moves a section of the second adhesive tape J2 from the second adhesive supply module 34 to the second adhesive application component 22.

[0155] In some specific embodiments, see Figure 3 and Figure 6 When it is necessary to achieve the goal of the first adhesive transfer module 352 transferring a section of the first adhesive tape J1 from the first adhesive supply module 32 to the first adhesive application component 21, and the second adhesive transfer module 353 transferring a section of the second adhesive tape J2 from the second adhesive supply module 34 to the second adhesive application component 22, firstly, the adhesive transfer drive module 351 can drive the first adhesive transfer module 352 and the second adhesive transfer module 353 to slide along the positive direction of the X-axis, so that the first adhesive transfer module 352 picks up the first adhesive tape J1 from the first adhesive supply module 32 and the second adhesive transfer module 353 picks up the second adhesive tape J2 from the second adhesive supply module 34. Then, the adhesive transfer drive module 351 can drive the first adhesive transfer module 352 and the second adhesive transfer module 353 to slide along the negative direction of the X-axis, so that the first adhesive transfer module 352 transfers a section of the first adhesive tape J1 to the first adhesive application component 21 and the second adhesive supply module 34 transfers a section of the second adhesive tape J2 to the second adhesive application component 22.

[0156] Since the first glue-handling module 352 is slidably disposed on the first glue-preparing mounting component 31 and connected to the glue-handling drive module 351, and the second glue-handling module 353 is slidably disposed on the second glue-preparing mounting component 33 and connected to the glue-handling drive module 351, when the glue-handling drive module 351 drives the first glue-handling module 352 and the second glue-handling module 353 to move, the movement of the first glue-handling module 352 and the second glue-preparing mounting component 33 can be made more stable under the guiding effect of the first glue-preparing mounting component 31 and the second glue-preparing mounting component 33.

[0157] The first glue transfer module 352 can be slidably mounted on the first glue preparation mounting component 31 via a slide rail assembly, or it can be slidably mounted on the first glue preparation mounting component 31 in other ways. This embodiment does not limit this.

[0158] Similarly, the way in which the second glue transfer module 353 is slidably disposed on the second glue preparation mounting component 33 can be similar to the way in which the first glue transfer module 352 is slidably disposed on the first glue preparation mounting component 31, and will not be described again in this embodiment.

[0159] In some embodiments, see Figure 1 , Figure 3 and Figure 6 The first adhesive transfer module 352 and the second adhesive transfer module 353 are both located on the first side of the mounting component 1. Figure 1 At least part of the glue-handling drive module 351 is located on the second side of the mounting component 1 opposite to the first side (on the left side of the mounting component 1). Figure 1 (Right side of mounting component 1).

[0160] This arrangement allows the first adhesive transfer module 352 and the second adhesive transfer module 353, along with the adhesive transfer drive module 351, to be located on both sides of the mounting component 1. This makes full use of the space on both sides of the mounting component 1, resulting in a more compact structure and smaller size for the entire adhesive application mechanism 100.

[0161] In some embodiments, see Figure 1 , Figure 6 and Figure 7 , Figure 7 yes Figure 6 The schematic diagram of the adhesive transfer drive module 351 shows that the adhesive transfer drive module 351 includes a support 3511, an adhesive transfer drive component 3512, a first connecting rod 3513, and a second connecting rod 3514. The support 3511 is disposed on the second side of the mounting component 1, the adhesive transfer drive component 3512 is disposed on the support 3511, the first connecting rod 3513 is slidably inserted through the mounting component 1, with one end on the second side connected to the adhesive transfer drive component 3512 and the other end on the first side connected to the first adhesive transfer module 352, and the second connecting rod 3514 is slidably inserted through the mounting component 1, with one end on the second side connected to the adhesive transfer drive component 3512 and the other end on the first side connected to the second adhesive transfer module 353.

[0162] Since the first connecting rod 3513 is slidably inserted through the mounting part 1 and its second end is connected to the glue-handling drive part 3512 and its first end is connected to the first glue-handling module 352, and the second connecting rod 3514 is slidably inserted through the mounting part 1 and its second end is connected to the glue-handling drive part 3512 and its first end is connected to the second glue-handling module 353, when the glue-handling drive part 3512 drives the first connecting rod 3513 and the second connecting rod 3514 to slide synchronously, the purpose of synchronously driving the first glue-handling module 352 and the second glue-handling module 353 to slide can be achieved.

[0163] It can be seen that the first glue-handling module 352 and the second glue-handling module 353 can be synchronously driven to slide through the same glue-handling drive component 3512, without the need to set up independent glue-handling drive components 3512 for each of the first glue-handling module 352 and the second glue-handling module 353. Therefore, on the one hand, the structure of the entire glue-handling module 35 can be made more compact, and on the other hand, it can also reduce the number of glue-handling drive components 3512 and reduce the cost of the glue-handling module 35.

[0164] The aforementioned glue-handling drive component 3512 can be a motor or a cylinder, etc., and this embodiment does not limit it.

[0165] In some embodiments, see Figure 7 The glue handling drive module 351 also includes a first lead screw 3515 and a first lead screw moving part 3516, the first lead screw 3515 extending along the extension direction of the first connecting rod 3513 ( Figure 7 The first lead screw moving part 3516 is threadedly connected to the first lead screw 3515, and the first connecting rod 3513 and the second connecting rod 3514 are both connected to the first lead screw moving part 3516.

[0166] In this way, when the glue-carrying drive component 3512 drives the first lead screw 3515 to rotate, it can drive the first lead screw moving component 3516 to slide back and forth along the extension direction of the first connecting rod 3513, thereby achieving the purpose of driving the first connecting rod 3513 and the second connecting rod 3514 to slide along the extension direction of the first connecting rod 3513.

[0167] In some embodiments, see Figure 3 and Figure 6 The first glue-handling module 352 includes a first moving component 3521, a glue-pulling roller drive component 3522, a glue-pulling roller mounting component 3523, and a glue-pulling roller 3524, wherein the first moving component 3521 moves along a first direction ( Figure 6 A glue-pulling roller drive component 3522 is slidably mounted on the first glue-preparing mounting component 31 and connected to the glue-handling drive module 351 in the X-axis direction. A glue-pulling roller drive component 3522 is mounted on the first moving component 3521. A glue-pulling roller mounting component 3523 is connected to the glue-pulling roller drive component 3522. The glue-pulling roller drive component 3522 is used to drive the glue-pulling roller mounting component 3523 along the second direction (X-axis direction). Figure 6 The adhesive roller 3524 moves closer to or further away from the first adhesive application assembly 21 in the Z-axis direction. The adhesive roller 3524 is rotatably mounted on the adhesive roller mounting part 3523. The adhesive roller 3524 is used to stick the first tape J1 to itself when rotating. The adhesive transfer drive module 351 is used to drive the first moving part 3521 to slide along the first direction so that the adhesive roller 3524 pulls out a section of the first tape J1 from the first adhesive supply module 32. The adhesive roller 3524 is also used to flatten the tape stuck to itself on the first adhesive application assembly 21 when rotating.

[0168] In this embodiment, when it is necessary to place a section of first tape J1 onto the first adhesive application assembly 21 via the first adhesive transfer module 352, with the adhesive roller 3524 positioned directly above the first tape J1, firstly, the adhesive roller drive 3522 can drive the adhesive roller mounting component 3523 along the second direction ( Figure 6 The first moving component 3521 moves closer to the first adhesive application assembly 21 (in the Z-axis direction), causing the adhesive roller 3524 to move to the adhesive surface of the first adhesive tape J1. Then, the adhesive transfer drive module 351 can drive the first moving component 3521 along the positive direction of the first direction (in the Z-axis direction). Figure 6 The roller 3524 slides in the positive direction of the X-axis, causing it to move in the positive direction of the first direction, so that the roller 3524 rotates counterclockwise relative to the first tape J1 and the first tape J1 is attached to the roller 3524.

[0169] Next, the rubber roller drive 3522 can drive the rubber roller mounting 3523 along the second direction ( Figure 6 The adhesive roller 3524 moves away from the first adhesive application assembly 21 in the Z-axis direction, creating a certain distance between the adhesive roller 3524 and the first adhesive application assembly 21 in the second direction. Then, the adhesive transfer drive module 351 can drive the first moving member 3521 in the negative direction of the first direction. Figure 6 The adhesive roller 3524 slides along the negative direction of the X-axis to pull out a section of the first adhesive tape J1 from the first adhesive supply module 32. This section of the first adhesive tape J1 can be positioned just above the first adhesive application assembly 21. Next, the adhesive roller drive 3522 can drive the adhesive roller mounting component 3523 to slide again along the second direction (the negative direction of the X-axis). Figure 6 The first adhesive tape J1 moves closer to the first adhesive application assembly 21 in the Z-axis direction, causing the first adhesive tape J1 to abut against the first adhesive application assembly 21. Finally, the adhesive transfer drive module 351 can drive the first moving member 3521 to move in the negative direction of the first direction (in the Z-axis direction). Figure 6 The adhesive roller 3524 slides in the negative direction of the X-axis to rotate clockwise relative to the first adhesive tape J1, thereby flattening the adhesive tape adhered to itself onto the first adhesive assembly 21.

[0170] As can be seen, the adhesive roller 3524 can cleverly utilize the adhesiveness of the first adhesive tape J1 to pick it up, and achieve the purpose of pulling out a section of the first adhesive tape J1 from the first adhesive supply module 32 during the negative movement of the adhesive roller 3524 along the first direction, without the need for gripping the first adhesive tape J1 by means of clamps. Therefore, on the one hand, the structure of the first adhesive handling module 352 can be simplified, reducing the cost of the first adhesive handling module 352. On the other hand, there is no need to reserve space for the opening and closing of the grippers, making the structure of the entire first adhesive handling module 352 more compact. Furthermore, there is no need to consider the interference between the grippers and the first adhesive application component 21 during the opening and closing of the grippers. Moreover, the first adhesive tape J1 does not need to protrude beyond the edge of the first adhesive application component 21 for gripping by the grippers, allowing the first adhesive tape J1 to be completely placed on the first adhesive application component 21, thereby making the first adhesive tape J1 more stably placed on the first adhesive application component 21.

[0171] It should be noted that the first moving part 3521 and the rubber roller mounting part 3523 mentioned above can be plate-shaped structures or other possible structures, and this embodiment does not limit them. The rubber roller driving part 3522 mentioned above can be a cylinder, electric cylinder or motor, etc., and this embodiment does not limit them.

[0172] In some embodiments, see Figure 6 The glue preparation assembly 3 also includes a first tape cutter 36, which is used to cut the first tape J1 so that a section of the first tape J1 is detached from the first glue supply module 32.

[0173] By setting the first tape cutting component 36, a section of the first tape J1 can be detached from the first adhesive supply module 32 by cutting, thus preparing for the subsequent pasting of the section of the first tape J1 onto the material belt L by the first adhesive application component 21.

[0174] The first tape cutting component 36 mentioned above may include a cutter and a cutter driving component. The cutter driving component is disposed on the first adhesive preparation mounting component 31, and the cutter is connected to the cutter driving component. The cutter driving component drives the cutter to move in a direction closer to or away from the first tape J1, thereby achieving the purpose of cutting the first tape J1.

[0175] The aforementioned cutting drive component can be a pneumatic cylinder or an electric cylinder, etc., and this embodiment does not limit it.

[0176] In some embodiments, see Figure 6 The glue preparation assembly 3 also includes a first tape clamping assembly 37. The first tape clamping assembly 37 is located between the first glue supply module 32 and the first tape cutting component 36 along the conveying path of the first tape J1. That is, the first tape clamping assembly 37 is located downstream of the first glue supply module 32. The tape clamping assembly is used to clamp or release the first tape J1.

[0177] Since the first tape clamping assembly 37 is located between the first glue supply module 32 and the first tape cutting component 36 along the conveying path of the first tape J1, when the first tape cutting component 36 needs to cut the first tape J1, the first tape clamping assembly 37 can clamp the first tape J1 to ensure that the first tape cutting component 36 can accurately and stably cut the first tape J1. When it is necessary to pull a section of the first tape J1 from the first glue supply module 32 through the tape pulling roller 3524, the first tape clamping assembly 37 can release the first tape J1 to ensure that the tape pulling roller 3524 can pull a section of the first tape J1 from the first glue supply module 32.

[0178] There are multiple ways to implement the first adhesive tape assembly 37 described above. In the first possible implementation, see [link to relevant documentation]. Figure 6 , Figure 8 and Figure 9 , Figure 8 yes Figure 6 A schematic diagram of the structure of the first adhesive tape assembly 37 from another perspective. Figure 9 yes Figure 8 The first tape clamping assembly 37 is shown in a cross-sectional view at position AA. The first tape clamping assembly 37 includes a first clamping member 371, a second clamping member 372, and a pushing member 373. At least one of the second clamping member 372 and the first clamping member 371 can move in a direction closer to or farther from the other to clamp or release the first tape J1. The pushing member 373 is slidably disposed on the first clamping member 371 in a direction closer to or farther from the second clamping member 372, so that the pushing member 373 protrudes or is recessed in the clamping surface of the first clamping member 371.

[0179] With this configuration, when the first tape J1 is attached to the first clamping member 371, the pushing member 373 can protrude from the clamping surface of the first clamping member 371, which can push the first tape J1, thereby peeling the first tape J1 off the first clamping member 371.

[0180] To prevent the first tape J1 from sticking to the pushing end of the pushing member 373, an anti-stick coating can be provided on the pushing end of the pushing member 373. The anti-stick coating can be a polytetrafluoroethylene coating or the like, as long as it can prevent sticking. This embodiment does not limit this.

[0181] It should be noted that there are multiple ways to enable at least one of the second clamping member 372 and the first clamping member 371 to move towards or away from the other. In one possible implementation, see [link to relevant documentation]. Figure 8 and Figure 9The second clamping member 372 and the first clamping member 371 can be respectively disposed on the two jaws of the clamping cylinder. Of course, they can also be implemented in other possible ways, and this embodiment does not limit them.

[0182] The aforementioned pusher 373 can be slidably disposed on the first clamping member 371 in a direction close to or far from the second clamping member 372 in various ways. In one possible implementation, see [link to relevant documentation]. Figure 9 The first clamping member 371 may be provided with a guide groove 3711. The guide groove 3711 passes through the first clamping member 371 along the direction of movement of the second clamping member 372 or the first clamping member 371. The push member 373 is slidably inserted into the guide groove 3711 along the through direction of the guide groove 3711. The cylinder can drive the push member 373 to slide along the guide groove 3711 so that the push member 373 protrudes or is recessed into the clamping surface of the first clamping member 371.

[0183] Of course, the pusher 373 can also be slidably disposed on the first clamping member 371 in other ways along the direction of approaching or moving away from the second clamping member 372, and this embodiment does not limit this.

[0184] There are multiple ways to implement the first adhesive tape assembly 37 described above. In a second possible implementation, see [link to second possible implementation]. Figure 6 , Figure 8 and Figure 9 The first tape clamping assembly 37 includes a first clamping member 371, a second clamping member 372, and a pushing member 373. The first clamping member 371 can move in a direction close to or away from the second clamping member 372 to clamp or release the first tape J1. The pushing member 373 is fixedly installed and is used to be recessed or protruded from the clamping surface of the first clamping member 371 when the first clamping member 371 moves in a direction close to or away from the second clamping member 372.

[0185] Since the pusher 373 is fixedly installed, and when the first clamping member 371 moves towards or away from the second clamping member 372, the pusher 373 can be recessed or protruded from the clamping surface of the first clamping member 371. Therefore, during the movement, the first clamping member 371 can not only clamp or release the first tape J1, but also push the pusher 373 to push the first tape J1 that is stuck to the clamping surface of the first clamping member 371. There is no need to set an independent driving member for the pusher 373 to drive the pusher 373 to push the first tape J1. The structure is ingeniously designed, which can simplify the structure of the first tape clamping assembly 37 and reduce the cost of the first tape clamping assembly 37.

[0186] In some embodiments, see Figure 2 and Figure 3The first adhesive application component 21 includes a first adsorption member 211 and a second adsorption member 212. The first adsorption member 211 is used to adsorb or release a section of first adhesive tape J1, and the second adsorption member 212 is used to adsorb or release material strip L. The first adsorption member 211 is also used to stick a section of first adhesive tape J1 to material strip L.

[0187] Since the first adsorption member 211 can adsorb or release a section of the first tape J1, when the first adsorption member 211 adsorbs a section of the first tape J1, it can achieve the purpose of placing a section of the first tape J1 stably in the first adhesive assembly 21.

[0188] Among them, see Figure 3 The first adsorption member 211 can be a plate-shaped structure with multiple air intake holes. Of course, in other embodiments, the first adsorption member 211 can also be other possible structures, which are not limited in this embodiment.

[0189] Since the second adsorption member 212 can adsorb or release the material belt L, when it is necessary to stick a section of the first tape J1 to the material belt L through the first adsorption member 211, firstly, the material belt L can be adsorbed by the second adsorption member 212 to fix the material belt L. Then, it can better ensure that a section of the first tape J1 can be stuck to the material belt L through the first adsorption member 211.

[0190] The structure of the second adsorption element 212 may be the same as or similar to that of the first adsorption element 211, and this embodiment does not limit this.

[0191] In some embodiments, see Figure 2 The first adhesive application assembly 21 also includes a flip drive module 213, which is disposed on the mounting component 1 and is used to drive the first adhesive application assembly 21 to flip so that the first adsorption member 211 faces the material strip L or the second adsorption member 212 faces the material strip L.

[0192] Since the flip drive module 213 can drive the first adhesive application component 21 to flip, and can make the first adsorption member 211 face the material strip L or the second adsorption member 212 face the material strip L, when it is necessary to adsorb the material strip L by the second adsorption member 212, the flip drive module 213 can drive the first adhesive application component 21 to flip, so that the second adsorption member 212 faces the material strip L and is in the adsorption state of the material strip, thus facilitating the adsorption of the material strip L by the second adsorption member 212.

[0193] When it is necessary to attach a section of first tape J1 to the material strip L via the first adsorption member 211, the flip drive module 213 can drive the first adhesive application component 21 to flip, so that the first adsorption member 211 faces the material strip L and is in the adhesive application state. This makes it easier for the first adsorption member 211 to attach a section of first tape J1 to the material strip L.

[0194] As can be seen, by driving the first adhesive application component 21 to flip through the flip drive module 213, the first adhesive application component 21 can switch between the adsorption material strip state and the adhesive application state, which is very flexible.

[0195] The aforementioned flipping drive module 213 can be a pneumatic cylinder or an electric cylinder, etc., and this embodiment does not limit it.

[0196] In some embodiments, see Figure 3 , Figure 10 and Figure 11 , Figure 10 yes Figure 3 A schematic diagram of the adhesive application mechanism 100 from the positive X-axis view. Figure 11 yes Figure 3 The schematic diagram of the adhesive applicator 100, omitting some structural components, shows that the first adhesive applicator assembly 21 also includes a movement drive module 214. The movement drive module 214 is disposed on the mounting component 1 and is used to drive the first adhesive applicator assembly 21 towards or away from the second adhesive applicator assembly 22. Figure 3 (Movement in the Y-axis direction).

[0197] Among them, see Figure 3 The structure of the second adhesive component 22 can be the same as or similar to that of the first adhesive component 21, and the second adhesive component 22 can be symmetrically arranged with the first adhesive component 21.

[0198] Specifically, see Figure 2 The second adhesive component 22 may include a third adsorption element 221 and a fourth adsorption element 222. The third adsorption element 221 may have the same or similar structure as the first adsorption element 211, which will not be described in detail here. The structure of the fourth adsorption element 222 may have the same or similar structure as the second adsorption element 212, which will not be described in detail here.

[0199] When the moving drive module 214 drives the first adhesive application component 21 to move closer to or further away from the second adhesive application component 22, the material tape L can be clamped between the first adhesive application component 21 and the second adhesive application component 22, thereby achieving the purpose of tape splicing.

[0200] Specifically, see Figure 12 , Figure 12 This is a schematic diagram of a splicing process provided in one embodiment of this application. When it is necessary to bond the tail end of the first material strip L1 to the starting end of the second material strip L2, please refer to [the diagram]. Figure 12In state ①, with the second adsorption member 212 adsorbing the first material strip L1 and the fourth adsorption member 222 adsorbing the second material strip L2, firstly, under the driving action of the moving drive module 214, the second adhesive assembly 22 and the first adhesive assembly 21 can approach each other. When the second adhesive assembly 22 and the first adhesive assembly 21 approach each other, the material strip cutter 223 set on the second adhesive assembly 22 can cut the first material strip L1 and the second material strip L2, so that the first material strip L1 produces a tail end and the second material strip L2 produces a starting end (state ②). Furthermore, the fourth adsorption member 222 can stop adsorbing the second material strip L2 and the second adsorption member 212 can start adsorbing the second material strip L2, so that both the first material strip L1 and the second material strip L2 are adsorbed to the second adsorption member 212 (state ③).

[0201] Next, the flipping drive module of the second adhesive application assembly 22 can drive the second adhesive application assembly 22 to flip, so that the third adsorption member 221 faces the material strip L (in state ④), and so that a section of the second adhesive strip J2 on the third adsorption member 221 is attached to the tail end of the first material strip L1 and the starting end of the second material strip L2. Figure 5 (Mid-state).

[0202] Next, the flipping drive module of the first adhesive application assembly 21 can drive the first adhesive application assembly 21 to flip, so that the first adsorption member 211 faces the belt L (state ⑤), and so that a section of the first adhesive tape J1 on the first adsorption member 211 is attached to the tail end of the first material belt L1 and the starting end of the second material belt L2. Figure 5 (Middle state). Finally, by moving the first adhesive assembly 21 and the second adhesive assembly 22 away from each other (middle state), the purpose of splicing can be achieved.

[0203] See Figure 2 and Figure 4 This application also provides an automatic roll changing device 200, including a first unwinding shaft 201, a second unwinding shaft 202, and an adhesive applicator 100, wherein the first unwinding shaft 201 is used to load a first roll of material, the first roll of material is used to unwind a first strip L1 through the strip-jointing mechanism 2, the second unwinding shaft 202 is used to load a second roll of material, the second roll of material is used to unwind a second strip L2 through the strip-jointing mechanism 2.

[0204] The first adhesive application assembly 21 is used to attach a section of first adhesive tape J1 to the tail end of the first material strip L1 and the starting end of the second material strip L2, with the first adhesive tape J1 located on the first side of the material strip L. The second adhesive application assembly 22 is used to attach a section of second adhesive tape J2 to the tail end of the first material strip L1 and the starting end of the second material strip L2, with the second adhesive tape J2 located on the second side of the material strip L opposite to the first side.

[0205] In particular, since the adhesive applicator 100 can automatically prepare adhesive, it can improve tape splicing efficiency while reducing the labor intensity of personnel. Based on this, when the adhesive applicator 100 is applied to the automatic roll changing device 200, it can improve tape splicing efficiency while reducing the labor intensity of personnel.

[0206] In addition, by setting a first unwinding shaft 201 and a second unwinding shaft 202, when the first strip L1 on the first unwinding shaft 201 is unwound, the tail end of the first strip L1 and the starting end of the second strip L2 can be automatically attached together to achieve automatic strip splicing. The whole process does not require stopping the machine. Therefore, when the automatic roll changing device 200 is applied in the winding equipment 300, the winding equipment 300 can process continuously without stopping the machine, which can improve the efficiency of the winding equipment 300 in processing battery cells.

[0207] In some embodiments, see Figure 4 The automatic roll changing device 200 also includes a take-up roller assembly 203, which is located downstream of the tape receiving mechanism 2. The take-up roller assembly 203 includes a first take-up roller 2031 and a second take-up roller 2032. Both the first take-up roller 2031 and the second take-up roller 2032 are rotatably arranged. The first take-up roller 2031 is used to take up the first tape L1, and the second take-up roller 2032 is used to take up the second tape L2.

[0208] By setting a second take-up roller 2032, when the winding equipment 300 is winding the first strip L1, the second strip L2 on the second unwinding shaft 202 can be pre-positioned on the second take-up roller 2032. Figure 4 (In the middle state), this prepares for the subsequent cutting of the second strip L2 to generate the starting end for splicing.

[0209] Similarly, by setting the first take-up roller 2031, when the winding equipment 300 is winding the second strip L2, the first strip L1 on the first unwinding shaft 201 can be arranged in advance on the first take-up roller 2031. In this way, it can prepare for the subsequent cutting of the first strip L1 to generate the starting end for the strip connection.

[0210] However, when gluing the tail end of the first strip L1 and the beginning end of the second strip L2 together, see... Figure 13 , Figure 13 This is a structural diagram showing the misalignment of the first material strip L1 and the second material strip L2. Misalignment of the first material strip L1 and the second material strip L2 may occur. Figure 13 (As shown by the dashed line), to avoid this situation, in some embodiments, see... Figure 3 and Figure 13 At least one of the first take-up roller 2031 and the second take-up roller 2032 can be along the axial direction of the first take-up roller 2031. Figure 3The X-axis direction is movably mounted on the mounting part 1.

[0211] With this configuration, when the first material strip L1 and the second material strip L2 are misaligned, by moving at least one of the first take-up roller 2031 and the second take-up roller 2032 along the axial direction of the first take-up roller 2031, the first material strip L1 and the second material strip L2 can be realigned. Figure 13 (As shown by the solid line in the middle), which makes the splicing effect better.

[0212] It should be noted that when the automatic roll changing device 200 is applied to the winding equipment 300, as winding proceeds, the first material strip L1 can be understood as a working material strip or a spare material strip. Similarly, the second material strip L2 can also be understood as a working material strip or a spare material strip.

[0213] In some embodiments, see Figure 10 and Figure 14 , Figure 14 yes Figure 10 A partial cross-sectional view of the take-up roller assembly 203 from another perspective (some structures omitted). The take-up roller assembly 203 also includes a take-up roller support 2033, a take-up roller moving part 2034, and a take-up roller moving drive part 2035. The take-up roller support 2033 is disposed on the mounting part 1. The first take-up roller 2031 and the second take-up roller 2032 are rotatably mounted on the take-up roller moving part 2034. The take-up roller moving drive part 2035 is disposed on the take-up roller support 2033 and is used to drive the take-up roller moving part 2034 to move axially along the first take-up roller 2031.

[0214] Since both the first take-up roller 2031 and the second take-up roller 2032 are rotatably mounted on the take-up roller moving member 2034, when the take-up roller moving drive member 2035 drives the take-up roller moving member 2034 to move along the axial direction of the first take-up roller 2031, it can simultaneously drive the first take-up roller 2031 and the second take-up roller 2032 to move along the axial direction of the first take-up roller 2031. That is, the same take-up roller moving drive member 2035 can simultaneously drive the first take-up roller 2031 and the second take-up roller 2032 to move along the axial direction of the first take-up roller 2031, eliminating the need to set up separate take-up roller moving drive members 2035 for the second take-up roller 2032 and the first take-up roller 2031, thereby achieving the goal of reducing the cost of the automatic roll changing device 200.

[0215] The aforementioned take-up roller moving drive 2035 can be a motor. The take-up roller moving drive 2035 can drive the take-up roller moving part 2034 to move along the axial direction of the first take-up roller 2031 through a lead screw structure or the like. This embodiment will not be described in detail here.

[0216] In some embodiments, see Figure 10and Figure 14 The take-up roller assembly 203 further includes a take-up roller rotation drive 2036 and a pulley structure 2037. The take-up roller rotation drive 2036 is disposed on the take-up roller moving part 2034, and the pulley structure 2037 is connected to the first take-up roller 2031 and the second take-up roller 2032 for transmission. The take-up roller rotation drive 2036 is used to synchronously drive the first take-up roller 2031 and the second take-up roller 2032 to rotate via the pulley structure 2037.

[0217] Since the pulley structure 2037 is connected to the first take-up roller 2031 and the second take-up roller 2032 respectively, when the take-up roller rotation drive 2036 drives either the first take-up roller 2031 or the second take-up roller 2032 to start rotating, the pulley structure 2037 can synchronously transmit the rotation action to the other. That is, under the action of the pulley structure 2037, the same take-up roller rotation drive 2036 can synchronously drive the first take-up roller 2031 and the second take-up roller 2032 to rotate, without the need to set up independent take-up roller rotation drives for the first take-up roller 2031 and the second take-up roller 2032, thereby reducing the number of take-up roller rotation drives and reducing the cost of the automatic roll changing device 200.

[0218] The pulley structure 2037 may include a timing pulley and a timing belt. The first take-up roller 2031 and the second take-up roller 2032 may each be provided with a timing pulley, and the timing belt is sleeved on the two timing pulleys.

[0219] Of course, the pulley structure 2037 can also be other possible structures, and this embodiment does not limit it.

[0220] In some embodiments, see Figure 4 The automatic roll changing device 200 also includes a first offset detection component 204, which is used to detect the offset of the first strip L1 along the axial direction of the first take-up roller 2031.

[0221] By setting the first offset detection component 204, the offset of the first material strip L1 along the axial direction of the first take-up roller 2031 can be automatically detected, making the automatic roll changing device 200 more intelligent and more automated.

[0222] Further, see Figure 4 The automatic roll changing device 200 also includes a second offset detection component 205, which is used to detect the offset of the second strip L2 along the axial direction of the first take-up roller 2031.

[0223] Similarly, by setting the second offset detection component 205, the offset of the second strip L2 along the axial direction of the first take-up roller 2031 can be automatically detected, which can further make the automatic roll changing device 200 more intelligent and more automated.

[0224] In some embodiments, see Figure 4 and Figure 15 , Figure 15 yes Figure 4 The first offset detection component 204 is shown in a schematic diagram from another perspective. The first offset detection component 204 includes a sensor mounting base 2041, a first sensor 2042, and a second sensor 2043. The first sensor 2042 is disposed on the sensor mounting base 2041, and the second sensor 2043 is disposed on the sensor mounting base 2041. The detection ends of the first sensor 2042 and the second sensor 2043 are spaced apart to form a detection slot 2041a through which the first material belt L1 passes. The sensor mounting base 2041 is provided with an air blowing hole 2041b, which is used to blow air toward the detection ends of the first sensor 2042 and / or the detection ends of the second sensor 2043.

[0225] By providing an air blowing hole 2041b on the sensor mounting base 2041, and blowing air through the air blowing hole 2041b toward the detection end of the first sensor 2042 and / or the detection end of the second sensor 2043, dust on the detection end of the first sensor 2042 and / or the detection end of the second sensor 2043 can be blown away in time, thereby improving the detection accuracy of the first offset detection component 204.

[0226] In some embodiments, see Figure 4 and Figure 15 The sensor mounting base 2041 is provided with a material threading slot 2041c for the first material belt L1 to pass through. The first sensor 2042 and the second sensor 2043 are respectively located on both sides of the material threading slot 2041c along the width direction of the material threading slot 2041c.

[0227] By providing a material threading slot 2041c on the sensor mounting base 2041 for the first material strip L1 to pass through, the sensor mounting base 2041 can confine the first material strip L1 within the material threading slot 2041c, thereby preventing the first material strip L1 from shaking significantly.

[0228] Figure 16 This is a schematic diagram of the structure of a winding device 300 according to an embodiment of this application. See also... Figure 16 The winding equipment 300 includes an automatic winding device 200 and a winding needle 301.

[0229] The structure of the automatic roll changing device 200 can be the same as that of any of the automatic roll changing devices 200 described in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments. This embodiment will not repeat the description here.

[0230] In this embodiment, since the automatic winding device 200 can automatically connect the tape, the efficiency of the winding device 300 in processing battery cells can be improved when the winding device 300 includes the automatic winding device 200.

[0231] The above-mentioned winding equipment 300 for processing battery cells is only one possible application scenario given in this embodiment. Of course, the winding equipment 300 can also process other possible products, and this embodiment does not limit this.

[0232] By setting up the winding needle 301, when the winding needle 301 rotates, it can wind the material strip L around itself, thereby achieving the purpose of processing products, such as battery cells.

[0233] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
