[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on and claims priority to the international application with international application number PCT / CN2023 / 101879 and international application date June 21, 2023. The disclosure of the international application is hereby incorporated into this application as a whole. Technical Field

[0003] The present application relates to the field of gluing technology, and in particular to a gluing device, a battery production line and a gluing method. Background Art

[0004] In the production and manufacturing process of batteries, gluing equipment is often used to apply glue to the parts to be glued. For example, gluing is performed during battery assembly to achieve connections between components.

[0005] To ensure the glue coating area, the glue nozzle of the glue coating equipment needs to move to multiple positions. During the movement of the glue nozzle, how to ensure the stability of glue feeding is an urgent problem to be solved.

[0006] Summary of the Invention

[0007] In view of the above problems, the present application provides a glue coating device, a battery production line and a glue coating method to effectively ensure the stability of glue feeding.

[0008] In a first aspect, the present application provides a glue coating device comprising a nozzle assembly, a hose, and a support assembly. The nozzle assembly is configured to be movable for applying the glue to a workpiece surface. The hose is connected to the nozzle assembly to deliver the glue to the nozzle assembly. The support assembly supports the hose. The support assembly includes a bracket and a movable arm rotatably connected to the bracket, and the hose is mounted on the movable arm.

[0009] In the technical solution of the embodiment of the present application, a supporting device is provided to support the carrying hose, and the movable arm of the supporting device rotates relative to the bracket, and the hose is installed on the movable arm. In this way, when the nozzle device moves to apply glue, the connecting end of the hose and the nozzle device will also move with the nozzle device, thereby causing the entire hose to move under tension. Since the hose is installed on the movable arm, the movable arm will rotate relative to the bracket under the action of the gravity of the hose, thereby causing the hose to move with the nozzle device, and the glue liquid is transported to the nozzle device through the hose. There is no need to set the hose longer, so that the glue liquid contained in the hose can basically be directly transported to the nozzle device, so that the accurately measured glue can be transported to the nozzle device, thereby improving the stability of glue delivery.

[0010] In some embodiments, the support device further comprises a rotating shaft disposed on the bracket. The rotating shaft extends vertically, and the movable arm is configured to rotate about the rotating shaft. The movable arm is configured to rotate about a vertical axis. This allows the rubber hose to move within a horizontal plane, driven by the movable arm, with a larger range of movement, thereby better tracking the movement of the nozzle assembly.

[0011] In some embodiments, the support device further includes an elastic device disposed on the movable arm. The first end of the elastic device is connected to the movable arm, and the second end of the elastic device is mounted on a hose. The elastic device is disposed on the movable arm. The elastic device is used to mount the hose. The first and second ends of the elastic device are telescopically disposed. When the hose is subjected to force, the elastic device moves in the direction of the force and automatically returns to its original position after the force is removed. Thus, when the hose is not subjected to force, the elastic device automatically returns to its original position, thereby driving the hose back to its original position, thereby preventing the hose from colliding with other components during operation and being damaged.

[0012] In some embodiments, the movable arm is provided with a guide rail. The guide rail extends in a direction intersecting the axis of rotation of the movable arm, and an elastic device is slidably disposed along the guide rail. The elastic device is used to mount the hose. When the hose is pulled by the nozzle assembly, it drives the elastic device along the guide rail, thereby enabling the hose to follow the position of the nozzle assembly. Arranging the guide rail to extend in a direction intersecting the axis of rotation of the movable arm allows the hose to follow the position of the nozzle assembly within multiple degrees of freedom.

[0013] In some embodiments, the extension direction of the guide rail is perpendicular to the rotation axis of the movable arm. This arrangement enables the rubber hose to follow the position of the rubber nozzle device in a horizontal plane.

[0014] In some embodiments, the support device further includes a hose fixing block. The hose fixing block is disposed at the second end of the elastic device and has a fixing hole for inserting the hose. The hose fixing block is fixedly connected to the second end of the elastic device and is provided with a fixing hole extending through the thickness of the hose fixing block. The hose is inserted into the fixing hole. The fixing hole is configured to limit the position of the hose. When the hose is pulled by the nozzle device, the hose applies a force to the elastic device through the fixing hole.

[0015] In some embodiments, the hose includes a first hose for conveying a first adhesive liquid and a second hose for conveying a second adhesive liquid. The hose fixing block has a first fixing hole for inserting the first hose and a second fixing hole for inserting the second hose. The nozzle assembly is configured to mix and spray the first adhesive liquid conveyed by the first hose and the second adhesive liquid conveyed by the second hose. The first hose and the second hose are both fixedly mounted on the hose fixing block so that both hoses can move simultaneously with the nozzle assembly, ensuring synchronization of the movement of the two hoses and further improving the stability of adhesive delivery.

[0016] In some embodiments, the elastic device includes an elastic balancer. Using the elastic device as an elastic balancer makes the gluing apparatus of the present invention simple and compact. Furthermore, the elastic balancer has a high force tolerance, making the gluing apparatus of the present invention suitable for larger gluing scenarios.

[0017] In some embodiments, the device further includes a moving device configured to move the nozzle assembly. The moving device drives the nozzle assembly to move according to the shape and position of the workpiece. Furthermore, the moving device is configured to move according to the speed of the glue discharge to perform the coating, thereby improving the quality of the glue coating.

[0018] In some embodiments, a feeding device is further included, which is used to provide glue liquid to the glue hose.

[0019] In some embodiments, the feeding device includes a feeding device, a transfer device, and a metering device. The feeding device is used to transfer the glue liquid to the transfer device, which is used to stir the glue liquid and transfer the glue liquid to the metering device. The metering device is configured to deliver glue liquid to the nozzle assembly as needed. The feeding device of the present embodiment of the application uses the transfer device to stir the glue liquid to improve its uniformity, and the metering device accurately measures the amount of glue delivered to ensure the quality of the glue application.

[0020] In some embodiments, the gluing device includes a battery pack case gluing device, which is used to apply glue to the lower case of the battery pack to achieve a connection and fixation between the bottom of the battery cell and the lower case.

[0021] In a second aspect, the present application provides a battery production line, comprising the above-mentioned glue coating device. The glue coating device is used to apply glue to the surface of the battery.

[0022] In a third aspect, the present application provides a method for coating a glue, comprising the following steps:

[0023] Moving the workpiece to a set position; and

[0024] The glue nozzle device is controlled to move relative to the workpiece and output glue to apply the glue to the surface of the workpiece. During the movement of the glue nozzle device, the glue hose moves with the glue nozzle device, and the movable arm rotates relative to the bracket under the action of the glue hose.

[0025] In some embodiments, the gluing method further includes: after moving the workpiece to a set position, acquiring an image of the workpiece by an image acquisition device to acquire a starting position of gluing of the workpiece.

[0026] In some embodiments, controlling the nozzle device to move relative to the workpiece and output glue to apply the glue on the workpiece surface includes: controlling the nozzle device to move from a glue application starting position and controlling the nozzle device to output glue during the movement.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] In this application, battery cells may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application are not limited to this. The battery mentioned in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in this application may include a battery module or a battery pack, etc.

[0041] Batteries generally include a housing for enclosing one or more battery cells. The housing prevents liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0042] A battery cell includes an electrode assembly and an electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. A battery cell primarily operates by the movement of metal ions between the positive and negative electrode sheets. The positive electrode sheet includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive electrode collector. The uncoated positive electrode collector protrudes from the coated positive electrode collector, and the uncoated positive electrode collector serves as the positive electrode tab. For lithium-ion batteries, for example, the positive electrode current collector can be made of aluminum, and the positive electrode active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative electrode collector. The uncoated negative electrode collector protrudes from the coated negative electrode collector, and the uncoated negative electrode collector serves as the negative electrode tab. The negative electrode current collector can be made of copper, and the negative electrode active material can be carbon or silicon, among others. To ensure that high currents can pass without fusing, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together. The separator can be made of materials such as PP (polypropylene) or PE (polyethylene). Furthermore, the electrode assembly can be a wound or laminated structure, but the embodiments of the present application are not limited thereto.

[0043] In the related art, glue coating equipment is often used to apply glue to the parts to be coated. For example, in the production and manufacturing of batteries, glue is usually applied during battery assembly to achieve connections between components.

[0044] To ensure a consistent coating area, the nozzle assembly of the coating equipment must be moved to multiple positions using a drive mechanism, such as a robot. The nozzle assembly is connected to a hose that delivers the glue liquid to the nozzle assembly. In related technologies, the hose must be very long to ensure that the nozzle assembly can move over a wide range and still deliver glue. During research, it was discovered that a very long hose would cause the hose to coil excessively, resulting in a larger amount of glue being contained within the hose. This results in inaccurate glue metering and an inability to achieve consistent glue delivery.

[0045] To address the above issues, after in-depth research, the technical solutions of the embodiments of the present application were proposed. Referring to Figure 1, the gluing equipment provided in the embodiments of the present application supports the hose by providing a support device, and the movable arm of the support device is configured to be rotatable relative to the bracket. Thus, when the nozzle device moves, the hose is pulled by the nozzle device and moves. The gravity of the hose drives the movable arm to rotate relative to the bracket, thereby enabling the hose to follow the position of the nozzle device. This eliminates the need to set the hose longer, and effectively ensures the stability of the glue supply while ensuring accurate metering.

[0046] The structure and working process of the gluing equipment of the embodiment of the present application are described in detail below with reference to Figures 1 to 4.

[0047] As shown in FIG1 , the gluing device of an embodiment of the present application includes a nozzle device 50, a hose 20, and a support device 10. The nozzle device 50 is used to output glue. The nozzle device 50 is configured to be movably arranged to apply glue to the surface of a workpiece. The hose 20 is connected to the nozzle device 50 to transport the glue to the nozzle device 50. The support device 10 is used to support the hose 20. The support device 10 includes a bracket 11 and a movable arm 12 rotatably connected to the bracket 11. The hose is mounted on the movable arm.

[0048] As shown in Figures 1 to 3, the glue coating equipment provided in the embodiment of the present application supports the carrying hose 20 by setting a supporting device 10, and the movable arm 12 of the supporting device 10 rotates relative to the bracket 11, and the hose 20 is installed on the movable arm 12. In this way, when the nozzle device 50 moves to apply glue, the connection end between the hose 20 and the nozzle device 50 will also move with the nozzle device 50, thereby causing the entire hose 20 to be subjected to tension and move. Since the hose 20 is installed on the movable arm 12, the movable arm 12 will rotate relative to the bracket 11 under the action of the gravity of the hose 20, thereby causing the hose 20 to move with the nozzle device 50, and the glue liquid is transported to the nozzle device 50 through the hose 20. There is no need to set the hose 20 longer, so that the glue liquid contained in the hose 20 can basically be directly transported to the nozzle device 50, so that the accurately measured glue can be transported to the nozzle device 50, thereby improving the stability of glue feeding.

[0049] In some embodiments, the support device 10 further includes an elastic device 14. The first end of the elastic device 14 is connected to the movable arm 12, and the second end of the elastic device 14 is equipped with a hose 20. In the technical solution of the embodiment of the present application, the elastic device 14 is provided on the movable arm 12. The elastic device 14 is used to install the hose 20. The first and second ends of the elastic device 14 are arranged telescopically. When the hose 20 is subjected to force, the elastic device 14 moves in the direction of the force and automatically returns to its original position after the force is eliminated. In this way, when the hose 20 is not subjected to force, the elastic device 14 automatically returns to its original position and drives the hose 20 to return to its original position, so as to avoid the hose 20 from colliding with other components during operation and being damaged.

[0050] As shown in FIG3 , in one specific embodiment, the bracket 11 is a vertically extending column. In other embodiments not shown in the drawings, the bracket 11 may also be other structures, such as a column extending at an angle to the vertical direction, or a body structure, and the bracket 11 serves to support the movable arm 12.

[0051] The movable arm 12 is rotatably connected to the bracket 11. FIG3 exemplarily illustrates that the extension direction of the movable arm 12 is perpendicular to the extension direction of the bracket 11. In other embodiments not shown in the figures, the extension direction of the movable arm 12 may also be set at an angle to the extension direction of the bracket 11. This is sufficient as long as the movable arm 12 is rotatable relative to the bracket 11 so that the hose 20 can follow the movement of the nozzle assembly 50 in real time.

[0052] In some embodiments, as shown in Figure 3, the support device 10 further includes a rotating shaft 13 disposed on the bracket 11. The rotating shaft 13 extends vertically, and the movable arm 12 is configured to rotate about the rotating shaft 13. In other words, the movable arm 12 is configured to rotate about a vertical axis. This allows the hose 20, driven by the movable arm 12, to move within a horizontal plane, with a wider range of movement, thereby better tracking the movement of the nozzle assembly 50.

[0053] In some other embodiments, the rotation axis of the movable arm 12 may also have an angle with the vertical direction.

[0054] Specifically, as shown in Figure 3, a rotating shaft 13 is provided at the top of the bracket 11. The first end of the movable arm 12 is sleeved on the rotating shaft 13 to achieve rotation around the rotating shaft 13. The second end of the movable arm 12 is freely provided.

[0055] In some embodiments, the movable arm 12 is provided with a guide rail 16. The guide rail 16 extends in a direction intersecting the axis of rotation of the movable arm 12, and the elastic device 14 is configured to slide along the guide rail 16. The elastic device 14 is used to mount the hose 20. When the hose 20 is pulled by the nozzle assembly 50, it drives the elastic device 14 along the guide rail 16, thereby enabling the hose 20 to follow the position of the nozzle assembly 50. Arranging the guide rail 16 to extend in a direction intersecting the axis of rotation of the movable arm 12 allows the hose 20 to follow the position of the nozzle assembly 50 in multiple degrees of freedom.

[0056] As shown in FIG3 , in some embodiments, the guide rail 16 extends perpendicular to the rotation axis of the movable arm 12. Specifically, the rotation axis of the movable arm 12 extends vertically, while the guide rail 16 extends horizontally, allowing the hose 20 to follow the movement of the nozzle assembly 50.

[0057] Referring to Figure 3 , the initial position of the elastic device 14 is near the free end of the movable arm 12. As the hose 20 moves under the pull of the nozzle assembly 50, it exerts a significant torque on the movable arm 12, thereby driving the movable arm 12. Simultaneously, the elastic device 14 is able to move along the guide rail 16. Specifically, for example, the elastic device 14 is provided with a slider that slidably engages with the guide rail.

[0058] In some embodiments, as shown in FIG4 , the support device 10 further includes a hose fixing block 15 . The hose fixing block 15 is disposed at the second end of the elastic device 14 . The hose fixing block 15 has a fixing hole for inserting the hose 20 . The hose fixing block 15 is fixedly connected to the second end of the elastic device 14 , and the hose fixing block 15 is provided with a fixing hole that penetrates the hose fixing block 15 in the thickness direction. The hose 20 is inserted into the fixing hole. The fixing hole is configured to limit the position of the hose 20. In this way, when the hose 20 is pulled by the nozzle device 50 , the hose 20 will apply a force to the elastic device 14 through the fixing hole.

[0059] In some embodiments, the hose 20 includes a first hose 21 for conveying a first glue liquid and a second hose 22 for conveying a second glue liquid. The hose fixing block 15 has a first fixing hole 151 for passing the first hose 21 and a second fixing hole 152 for passing the second hose 22. The nozzle device 50 is used to mix the first glue liquid conveyed by the first hose 21 and the second glue liquid conveyed by the second hose 22. Specifically, for example, the first hose 21 is used to convey glue A, and the second hose 22 is used to convey glue B. The first hose 21 conveys glue A to the nozzle device 50, and the second hose 22 conveys glue B to the nozzle device 50. The nozzle device 50 mixes glue A and glue B and applies them to the surface of the workpiece. The first hose and the second hose are both fixedly mounted on the hose fixing block so that both hoses can move simultaneously with the nozzle device, ensuring the synchronization of the movement of the two hoses and further improving the stability of glue delivery.

[0060] In some embodiments, as shown in FIG4 , the elastic device 14 includes an elastic balancer. Using the elastic device 14 as an elastic balancer makes the gluing apparatus of the present invention simple and compact. Furthermore, the elastic balancer has a high force tolerance, making the gluing apparatus of the present invention suitable for larger gluing scenarios.

[0061] In some embodiments, a moving device 40 is further included. The moving device 40 is configured to move the glue nozzle assembly 50. The moving device 40 moves the glue nozzle assembly 50 according to the shape and position of the workpiece. The moving device 40 is also configured to move according to the speed of glue discharge to improve glue coating quality.

[0062] In some embodiments, the mobile device 40 comprises a robot. The robot's movement control is more intelligent, improving the precision of the nozzle assembly's movement and enhancing the quality of glue application. The robot can be a six-axis robot. For example, the nozzle assembly 50 can be fixedly mounted at the end of the six-axis robot's working arm. This allows the nozzle assembly 50 to move in multiple degrees of freedom.

[0063] In some embodiments, as shown in FIG1 and FIG2 , a feeding device 80 is further included. The feeding device 80 is used to provide glue liquid to the glue tube 20 .

[0064] In some embodiments, the feeding device 80 includes a feeding device 81, a transfer device 82 and a metering device 83. The feeding device 81 is used to transport the glue liquid to the transfer device 82. The transfer device 82 is used to stir the glue liquid and transport the glue liquid to the metering device 83. The metering device 83 is configured to transport the glue liquid to the nozzle device 50 according to demand; specifically, the feeding device 81 is used to automatically transport the glue liquid from the raw material barrel to the transfer device 82. The transfer device 81 is used to stir the glue liquid evenly and remove air, and then transport the glue liquid to the metering device 83. The metering device 83 is used to transport the glue liquid to the nozzle device 50 and measure the amount of glue liquid. The feeding device 80 of the embodiment of the present application improves the uniformity of the glue liquid by setting the transfer device 81 to stir the glue liquid, and accurately measures the amount of glue liquid transported by the metering device 83 to ensure the quality of the glue coating.

[0065] In some embodiments, the present application further provides a battery production line. The battery production line includes the glue coating equipment of each of the above embodiments. The glue coating equipment is used to apply glue to the surface of the battery. The battery surface can be the surface of the battery case or the surface of the battery cell.

[0066] In some embodiments, the gluing device includes a battery pack case gluing device, which is used to apply glue to the lower case of the battery pack to achieve a connection and fixation between the bottom of the battery cell and the lower case.

[0067] In some other embodiments, the gluing equipment can also be used for but not limited to gluing the connection points between battery cells, the connection between battery cells and side panels, short panels, the connection points between batteries, and other scenarios requiring gluing.

[0068] Referring to FIG5 , the embodiment of the present application further provides a method for applying glue. The method of the embodiment of the present application includes:

[0069] Step 501: Move the workpiece to a set position.

[0070] Step 502 , controlling the nozzle device 50 to move relative to the workpiece and output glue to apply the glue to the workpiece surface. During the movement of the nozzle device 50 , the hose moves with the nozzle device 50 , and the movable arm 12 rotates relative to the bracket 11 under the action of the hose.

[0071] The gluing method of the embodiment of the present application first moves the workpiece to a set position, and then controls the nozzle device 50 to move relative to the workpiece to complete the application of the glue liquid. Moreover, the movement of the nozzle device 50 causes the hose to move under the pull of the nozzle device 50, and the movable arm 12 used to support the hose will rotate relative to the bracket 11 under the action of the hose, thereby realizing the hose following the position of the nozzle device, thereby effectively ensuring the stability of the glue supply under the condition of accurate measurement.

[0072] In some embodiments, the gluing method further includes, after moving the workpiece to a set position, acquiring an image of the workpiece through an image acquisition device to obtain the workpiece's starting position for gluing; controlling the nozzle device 50 to move from the gluing starting position and controlling the nozzle device 50 to output glue during movement. Specifically, for example, an image of the workpiece is acquired through the image acquisition device and a coordinate system is established based on the image of the workpiece, thereby determining the workpiece's starting position for gluing, i.e., coordinate information. Accurately acquiring the gluing starting position based on the image of the workpiece and using this gluing starting position to guide the movement starting position of the nozzle device 50 is beneficial for improving the accuracy of gluing. The structure of a specific embodiment of the gluing device of the present application is described in detail below with reference to Figures 1 to 4.

[0073] As shown in Figures 1 and 2, the glue coating equipment of the specific embodiment of the present application includes a supporting device 10, a glue hose 20, a moving device 40, a glue nozzle device 50, a waste glue barrel 60, a lifting device 70 and a feeding device 80.

[0074] The lifting device 70 achieves product positioning by lifting and positioning, thereby facilitating the gluing of the glue nozzle device 50 .

[0075] The feeding device 80 includes a feeding device 81, a transfer device 82, and a metering device 83. The feeding device 80 is used to supply liquid glue to the rubber hose 20. The feeding device 81 automatically transfers the liquid glue from the raw material barrel to the transfer device 82. The transfer device 82 stirs the glue evenly and removes air before transferring the liquid glue to the metering device 83. The metering device 83 delivers the liquid glue to the nozzle assembly 50 and measures the delivered amount of liquid glue.

[0076] The glue nozzle device 50 is used to mix the glue A and the glue B delivered by the first glue hose 21 and the second glue hose 22 and apply the mixture to the surface of the workpiece.

[0077] The moving device 40 (eg, a robot) is used to drive the nozzle device 50 to move according to demand. Specifically, the moving speed of the moving device 40 is configured to adapt to the glue dispensing speed of the nozzle device 50.

[0078] As shown in FIG. 3 and FIG. 4 , the supporting device 10 includes a bracket 11 , a movable arm 12 , a rotating shaft 13 , an elastic device 14 and a hose fixing block 15 .

[0079] A rotating shaft 13 is mounted at the top of the bracket 11. The first end of a movable arm 12 is rotatably connected to the rotating shaft 13, while the second end of the movable arm 12 is freely movable. An elastic device 14 is mounted on the movable arm 12. A hose fixing block 15 is mounted at the lower end of the elastic device 14. The hose is threaded through the fixing block 15. The elastic device 14 stretches when subjected to force and returns to its original position when the force is removed, thereby protecting the hose from damage.

[0080] The gluing equipment of this embodiment operates as follows: The AGV (Automated Guided Vehicle) moves the product to a designated position, where it is lifted and positioned by the lifting mechanism 70. The robot then takes a photo of the product to confirm the starting position for gluing. The robot then moves the nozzle assembly 50 and dispenses glue simultaneously. The movable arm 12 rotates relative to the bracket 11 as the hose moves, thereby following the movement of the nozzle assembly 50. After gluing is complete, the robot returns the nozzle assembly 50 to its original position, and the movable arm 12 also returns to its original position along with the hose. After the robot returns to its original position, the AGV receives a signal to leave and moves the product away.
