Obviously, the described embodiments are only part of the embodiments of the present application and are not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application. In addition, it should be understood that the specific implementation described herein is only used to illustrate and explain the present application and is not used to limit the present application. In the present application, the orientation words such as "upper" and "lower" generally refer to the upper and lower directions of the device in the actual use or working state, and specifically refer to the drawing direction in the drawings. The "inner" and "outer" refer to the contour of the device.

[0035] The power battery pack or energy storage battery pack includes a plurality of square battery modules arranged side by side, and adjacent two battery modules are bonded and fixed by foaming glue. A battery glue filling device for filling glue in the battery modules includes a glue filling nozzle. After the glue filling is completed, there is a lot of glue left inside and outside the glue filling nozzle. In the related art, only the residual glue inside the nozzle can be extruded by the built-in piston, and the glue outside or hanging on the nozzle cannot be effectively removed, thereby affecting the subsequent glue filling work using the nozzle.

[0036] Embodiments of the present application provide a battery glue filling device, which includes a glue filling device and a glue filling nozzle connected to the glue filling device.

[0037] The glue filling device can be a glue filling device provided in the related art for filling glue between square battery modules.

[0038] In some embodiments, as shown in Figures 1 to 3 The glue filling nozzle 10 includes a glue outlet pipe 2 and a cleaning assembly 20. The glue filling device and the glue filling nozzle 10 are connected by a connecting piece 1. The glue filling device drives the foaming glue to flow into the inner cavity of the connecting piece 1, and the foaming glue enters the glue outlet pipe 2 through the connecting piece 1. The connecting piece 1 can be a glue filling port of the glue filling device. The extrusion piston of the glue filling device pushes the sealant to flow into the inner cavity of the connecting piece 1 and enters the glue outlet pipe 2 through the connecting piece 1.

[0039] The cleaning assembly 20 includes a control valve assembly 3 and a cleaning member 4. The cleaning member 4 is used to transport a cleaning medium, which can be a cleaning liquid or a gas. The control valve assembly 3 is configured to control the communication and disconnection of the cleaning member 4 and the glue outlet pipe 2.

[0040] In the embodiment of the present application, the cleaning assembly comprises a cleaning member 4 for delivering cleaning medium and a control valve assembly 3 for controlling the connection and disconnection of the cleaning member 4 and the glue outlet pipe 2. When the glue filling device is in the process of glue filling, the control valve assembly 3 controls the disconnection of the cleaning member 4 and the glue outlet pipe 2, and the glue outlet pipe 2 is used for glue filling at the gap between two battery modules. When the glue filling device stops glue filling in the gap or after the glue filling is completed, the control valve assembly 3 controls the connection of the cleaning member 4 and the glue outlet pipe 2, and the cleaning medium provided by the cleaning member 4 enters the glue outlet pipe 2 to clean the glue outlet pipe 2.

[0041] It can be understood that the cleaning medium can be high-pressure gas or cleaning liquid. The high-pressure gas can blow away the residual glue attached to the inner wall or outer wall of the glue outlet pipe 2. The cleaning liquid can dissolve the residual glue attached to the inner wall or outer wall of the glue outlet pipe 2.

[0042] The control valve assembly is connected to an automatic control system, and the automatic cleaning of the glue outlet pipe can be realized by operating the control valve assembly through the automatic system, thereby realizing intermittent glue filling operation without blocking the glue outlet pipe.

[0043] In a specific implementation, the control valve assembly 3 comprises a control valve 31, an adjusting member 32 and a driving pipe 33.

[0044] Reference Figures 3 to 5 The control valve 31 is provided with a first interface 311 and a second interface 312, and the connecting member 1 is provided in the form of a connecting pipe structure. The connecting member 1 is connected to the first interface 311 by a nut, and the glue outlet pipe 2 is connected to the second interface 312 by a nut. The first interface 311 is arranged on the upper end face of the control valve 31, and the second interface 312 is arranged on the lower end face of the control valve 31. The control valve 31 is further provided with a first communication cavity 313 and a second communication cavity 314 in communication. The first communication cavity 313 is in communication with the second communication cavity 314 along the valve axis direction of the control valve 31, and the second communication cavity 314 is connected between the first interface 311 and the second interface 312 along the glue outlet axis direction of the glue outlet pipe 2. The valve axis direction of the control valve 31 is arranged perpendicularly to the glue outlet axis direction of the glue outlet pipe 2, that is, the valve axis direction of the control valve 31 is the y direction as shown in Figure 3 , and the glue outlet axis direction of the glue outlet pipe 2 is the x direction as shown in Figure 3 . The communication state of the second communication cavity 314 and the first communication cavity 313 is adjustable, thereby controlling the communication state of the first communication cavity 313 and the glue outlet pipe 2.

[0045] The adjusting member 32 is arranged to adjust the communication state between the second communication cavity 314 and the first communication cavity 313. In a specific embodiment, the adjusting member 32 comprises a piston, and the adjusting member 32 is movable along the valve axis of the control valve 31 in the second communication cavity 314. The communication port 315 between the second communication cavity 314 and the first communication cavity 313 is arranged in a constricted manner. As shown in Figure 3 and Figure 4 When the adjusting member 32 is located outside the communication port 315, the second communication cavity 314 and the first communication cavity 313 are in a communication state, and correspondingly, the first communication cavity 313 and the glue outlet pipe 2 are in a communication state. As shown in Figure 5 When the adjusting member 32 is moved into the communication port 315, the second communication cavity 314 and the first communication cavity 313 are in a non-communication state, and correspondingly, the first communication cavity 313 and the glue outlet pipe 2 are in a non-communication state.

[0046] The adjusting member 32 is arranged to be driven by hydraulic pressure to move in the first communication cavity 313. In a specific embodiment, as shown in Figure 2 and Figure 3 The control valve assembly 3 comprises two driving pipes 33, including a closing driving pipe 331 and an opening driving pipe 332. The closing driving pipe 331 is connected to one end of the first communication cavity 313 away from the communication port 315. When high-pressure liquid is introduced into the closing driving pipe 331, the high-pressure liquid in the closing driving pipe 331 provides a hydraulic driving force on one end of the adjusting member 32 to move the adjusting member 32 towards the communication port 315 and close the communication port 315. The opening driving pipe 332 is connected to the upper end of the first communication cavity 313 close to the communication port 315. When high-pressure liquid is introduced into the opening driving pipe 332, the high-pressure liquid in the opening driving pipe 332 provides a hydraulic driving force on the other end of the adjusting member 32 to move the adjusting member 32 away from the communication port 315 and open the communication port 315.

[0047] In a specific embodiment, continuing to refer to Figures 3 to 5The control valve 31 further comprises a hydraulic cavity 316, the closing driving pipe 331 is communicated with the hydraulic cavity 316, and the opening driving pipe 332 is communicated with the hydraulic cavity 316. The adjusting member 32 comprises a base portion 321 and a columnar portion 322 connected with each other. The base portion 321 is in contact with the inner wall of the hydraulic cavity 316 in the circumferential direction, and the outer diameter of the columnar portion 322 is smaller than that of the base portion 321. The base portion 321 is arranged to be movable in the hydraulic cavity 316, at least a part of the columnar portion 322 is movable in the first communicating cavity 313, and the end of the columnar portion 322 is necked to form a sealing portion for sealing the communicating port 315. When the high-pressure liquid is introduced into the closing driving pipe 331, the high-pressure liquid acts on one side of the base portion 321 to push the adjusting member 32 to move towards the communicating port 315. When the high-pressure liquid is introduced into the opening driving pipe 332, the high-pressure liquid acts on the other side of the base portion 321 to push the adjusting member 32 to move away from the communicating port 315.

[0048] In an embodiment, the control valve 31 further comprises a driving cavity 317, and the opening driving pipe 332 is communicated with the hydraulic cavity 316 through the driving cavity 317. The diameter of the driving cavity 317 is smaller than that of the hydraulic cavity 316, so that the high-pressure liquid introduced into the wider hydraulic cavity 316 through the narrower driving cavity 317 can provide a larger pushing force to the base portion 321 inside the hydraulic cavity 316.

[0049] It can be understood that, when the glue nozzle 10 is used to glue the battery module, the control valve assembly 3 controls the communicating port 315 to be in the closed state, so that the first communicating cavity 313 is not communicated with the glue outlet pipe 2. The glue introduced into the second communicating cavity 314 through the first interface 311 can only enter the glue outlet pipe 2. When the glue nozzle 10 stops gluing the battery module, the control valve assembly 3 controls the communicating port 315 to be in the open state, so that the first communicating cavity 313 is communicated with the glue outlet pipe 2. The cleaning medium provided by the cleaning member 4 can flow into the first communicating cavity 313 through the outlet of the cleaning member 4, and then enter the second communicating cavity 314 through the communicating port 315 of the first communicating cavity 313 and be provided to the glue outlet pipe 2, so as to clean the glue outlet pipe 2. After cleaning, the control valve assembly can be controlled to stop the cleaning operation and continue the intermittent gluing. During the intermittent gluing, the glue outlet pipe 2 will not be blocked because the glue nozzle 10 can realize automatic cleaning.

[0050] In some embodiments, the cleaning member 4 is connected to the control valve 31 and arranged close to the communication port 315. The cleaning member 4 comprises a valve 41 and a conduit 42, one end of the conduit 42 is provided with an opening 421, the other end of the conduit 42 is communicated with the inner cavity of the cleaning member 4, the valve 41 is arranged to control the communication state between the conduit 42 and the inner cavity of the cleaning member 4, when the valve 41 is opened, the conduit 42 is communicated with the inner cavity of the cleaning member 4, the cleaning medium added into the conduit 42 through the opening 421 can enter the inner cavity of the cleaning member 4, and then enter the first communication cavity 313 through the outlet of the cleaning member 4, and then provided to the glue outlet pipe 2 through the communication port 315.

[0051] In some embodiments, the glue outlet pipe 2 comprises a flow guide section 21 and a nozzle section 22 connected to each other, the flow guide section 21 is connected to the second interface 312, the flow guide section 21 is arranged in a tubular shape, and the nozzle section 22 is arranged in a flat shape, the nozzle section 22 is arranged to extend into the gap between the two adjacent battery modules, and the nozzle section 22 is arranged in a flat shape to facilitate the nozzle section 22 to extend into the gap between the two battery modules. The nozzle section 22 is arranged in a flat shape, and the width of the nozzle section 22 is greater than the outer diameter of the flow guide section 21, so that the nozzle section 22 has the effect of increasing the glue outlet flow, thereby improving the problem of uneven mixing of the two types of foaming glue due to small glue outlet flow of the nozzle section 22.

[0052] In some embodiments, the bottom end surface of the nozzle section 22 is arranged in a slope structure. It can be understood that if the bottom end surface of the nozzle section 22 is arranged in a flat structure, the residual glue will be dispersed and hung on the bottom end surface of the nozzle section 22, and the glue cannot be gathered into water droplets. When the bottom end surface of the nozzle section 22 is arranged in a slope structure, the residual glue will flow along the slope to the bottom of the slope, so that the glue is gathered into water droplets. It can be understood that the glue in the form of water droplets is relatively easy to blow away by blowing, thereby achieving sufficient cleaning of the residual glue outside the nozzle.

[0053] In some specific embodiments, as shown in Figure 3 The angle between the slope where the bottom end of the nozzle section 22 is located and the horizontal axis direction of the glue outlet pipe 2 is 15°-30°. The inventors have found through research that when the angle between the slope where the bottom end of the nozzle section 22 is located and the horizontal axis direction of the glue outlet pipe 2 is less than 15°, the inclination of the slope where the bottom end of the nozzle section 22 is located is smaller, and thus the flow guiding effect of the slope is smaller, which cannot provide sufficient gathering effect for the residual glue. When the angle between the slope where the bottom end of the nozzle section 22 is located and the horizontal axis direction of the glue outlet pipe 2 is greater than 30°, the slope where the bottom end of the nozzle section 22 is located occupies a larger height of the nozzle section 22, thereby affecting the glue filling effect of the nozzle section 22.

[0054] In some specific embodiments, as shown in Figure 2As shown, the outer diameter d of the glue nozzle section 22 is set to be smaller than the interval between two adjacent battery modules, so that the glue nozzle section 22 can be inserted into the gap between two adjacent battery modules, thereby achieving narrow-gap glue filling. The interval between two adjacent battery modules can be 3mm-6mm, the difference between the interval between two adjacent battery modules and the outer diameter of the glue nozzle section 22 is not greater than 1mm, and correspondingly the outer diameter of the glue nozzle section 22 is 2mm-5mm. In a specific implementation, the interval between two adjacent battery modules is 6mm, and the outer diameter of the glue nozzle section 22 of the glue outlet pipe 2 is 5mm. It can be understood that if the difference between the interval between two adjacent battery modules and the outer diameter of the glue nozzle section 22 is greater than 1mm, the glue filling efficiency of the glue nozzle section 22 will be affected. For example, if the interval between two adjacent battery modules is 6mm and the outer diameter of the glue nozzle section 22 is 2mm, the glue nozzle cannot be filled in one filling operation and needs to be back and forth to fill, thereby affecting the glue filling efficiency.

[0055] In some embodiments, as shown in Figure 5 As shown, the outer part of the glue nozzle section 22 of the glue outlet pipe 2 is also provided with an insulating sleeve 5, which surrounds the glue nozzle section 22 to provide insulation function for the glue nozzle section 22, and also prevents the glue nozzle section 22 of the glue outlet pipe 2 from scratching the battery modules when it is inserted into the gap between two battery modules.

[0056] The glue filling nozzle 10 in the embodiment of the present application can realize automatic cleaning function due to the configuration of the control valve assembly 3. When the battery glue filling equipment stops glue filling, the control valve 31 is controlled to drive the adjusting part 32 to open the communication port 315, and the cleaning part 4 is opened. The high-speed airflow can blow away the residual glue attached to the inner wall of the glue outlet pipe 2 and the bottom end of the glue outlet pipe 2, thereby achieving effective cleaning.

[0057] The battery glue filling equipment in the embodiment of the present application also includes a cleaning container. When the battery glue filling equipment stops glue filling, the glue outlet pipe 2 of the glue filling nozzle 10 is controlled by the automatic control equipment to be inserted into the cleaning container, and the glue outlet pipe 2 is fully soaked in the cleaning liquid in the cleaning container, thereby effectively improving the blockage of the glue outlet pipe 2 by residual glue.

[0058] The embodiments of the present application are described in detail above, and the principles and implementation modes of the present application are described by applying specific examples. The above description of the embodiments is only used to help understand the method of the present application and its core idea; at the same time, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed, and the above description should not be understood as a limitation of the present application.
