Description

Technical Field

[0001] The utility model relates to the technical field of gluing, in particular to a battery pack gluing device and a gluing head. Background Art

[0002] At present, in the assembly process of the battery pack, a gluing machine is usually used to first apply glue to the tray, and then the battery module is placed in the tray so that the bottom surface of the battery module is bonded and fixed to the tray. Existing gluing methods include manual gluing methods and semi-automatic gluing methods with pre-set gluing routes. However, the existing gluing methods have the following disadvantages: 1. When manual gluing is used, the labor cost is high, and the consistency of the amount of glue cannot be guaranteed. 2. When using a semi-automatic gluing method, since the amount of glue is a fixed value set in advance, when the flatness of the tray surface is not high (that is, it is convex or concave), the bottom surface of the battery module will not be firmly bonded to the tray, affecting the safety of the battery pack.

[0062] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0063] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0064] Please also read Figure 1-2 The present application provides a battery pack gluing device 100 , which includes a gluing component 10 , a contour scanner 20 , and a controller 30 .

[0065] The glue coating assembly 10 includes a driving mechanism 1 and a glue coating head 2 which are connected to each other. The driving mechanism 1 is used to drive the glue coating head 2 to move relative to a battery tray 200 for placing a battery module (not shown in the figure), so that the glue coating head 2 applies glue to various areas of the glue coating surface of the battery tray 200. The glue coating surface is a side of the battery tray 200 for placing the battery module.

[0066] The contour scanner 20 is used to perform a first scan on the glue-coated surface of the battery tray 200 before the glue-coating component 10 coats glue on the battery tray 200 to obtain first scanning data.

[0067] The controller 30 is electrically connected to the contour scanner 20, the glue coating head 2 and the driving mechanism 1, and is used to analyze and obtain the initial flatness of each area on the glue coating surface of the battery tray 200 based on the first scanning data output by the contour scanner 20, and in the process of controlling the glue coating component 10 to glue the battery tray 200, the controller 30 controls the glue coating head 2 to discharge glue at a corresponding discharge speed in each area according to the initial flatness of each area on the glue coating surface of the battery tray 200, and / or controls the driving mechanism 1 to move at a corresponding moving speed.

[0068] The initial flatness of each area on the glued surface of the battery tray 200 refers to the deviation of the height of each area on the glued surface of the battery tray 200 in the vertical direction relative to a preset glued reference plane. The first scanning data may include the height values ​​of each area on the glued surface of the battery tray 200 in the vertical direction. The controller 30 may compare the height values ​​of each area on the glued surface of the battery tray 200 in the vertical direction with the height value of the preset glued reference plane according to the first scanning data, thereby obtaining the initial flatness of each area on the glued surface of the battery tray 200. The preset glued reference plane may be determined according to the thickness requirement of the glue. In order to ensure that each area on the glued surface of the battery tray 200 can be effectively bonded to the battery module, the preset glued reference plane should be higher than the highest point on the glued surface of the battery tray 200 in the vertical direction.

[0069] When applying glue, the controller 30 can determine the target amount of glue required for each area on the glue-coated surface of the battery tray 200 according to the initial flatness of each area on the glue-coated surface of the battery tray 200. Specifically, an area with a larger flatness deviation value requires a larger target amount of glue, and an area with a smaller flatness deviation value requires a smaller target amount of glue. In this way, it can ensure that the glue-coated surface of the battery tray 200 remains flat after glue application, thereby improving the reliability and consistency of the bonding between the battery tray 200 and the battery module, and avoiding the problem of debonding of the battery module and the battery tray 200 due to poor flatness of the glue-coated surface of the battery tray 200.

[0070] It is not difficult to understand that the actual amount of glue applied by the glue coating component 10 on an area on the glue coating surface of the battery tray 200 is related to the moving speed of the driving mechanism 1 in the area and the glue discharging speed of the glue coating head 2 in the area. Specifically, the faster the moving speed of the driving mechanism 1 in the area, the less the actual amount of glue applied by the glue coating component 10 in the area, and the slower the moving speed of the driving mechanism 1 in the area, the more the actual amount of glue applied by the glue coating component 10 in the area; the faster the glue discharging speed of the glue coating head 2 in the area, the more the actual amount of glue applied by the glue coating component 10 in the area, and the slower the glue discharging speed of the glue coating head 2 in the area, the less the actual amount of glue applied by the glue coating component 10 in the area. Therefore, when the controller 30 controls the glue coating component 10 to apply glue to an area on the glue coating surface of the battery tray 200, it can control the glue coating head 2 to discharge glue at a corresponding glue discharging speed, and / or control the driving mechanism 1 to move at a corresponding moving speed, so that the actual amount of glue applied in the area is close to the required target amount of glue applied.

[0071] The battery pack gluing device 100 provided by the utility model performs a first scan on the gluing surface of the battery tray 200 through a contour scanner 20 to obtain first scanning data before gluing the battery tray 200, and analyzes the initial flatness of each area on the gluing surface of the battery tray 200 through a controller 30 according to the first scanning data, and adjusts the gluing speed of the gluing head 2 and / or the moving speed of the driving mechanism 1 according to the initial flatness of each area during the gluing process. In this way, dynamic control of the gluing amount of the gluing component 10 can be achieved, thereby ensuring that the gluing surface of the battery tray 200 remains flat after gluing, thereby improving the reliability and consistency of the bonding between the battery tray 200 and the battery module.

[0072] In some embodiments, the driving mechanism 1 is as follows Figure 2 The sliding module shown includes a base 11 , a first sliding component 12 and a second sliding component 13 .

[0073] The base 11 is provided with a plurality of Figure 2 The first slide rail 12 is provided with a first slide rail extending in the third direction (as shown in the Y-axis direction), and the first slide member 12 is provided on the first slide rail and can slide along the first slide rail. Figure 2 The second slide rail 10 extends in the X-axis direction (shown in the X-axis direction), and the second sliding component 13 is arranged on the second slide rail and can slide along the second slide rail. The glue coating head 2 and the contour scanner 20 are fixedly installed on the second sliding component 13. During the glue coating process, the battery tray 200 is fixedly placed in a preset position below the glue coating head 2 and the contour scanner 20. At this time, the length direction of the battery tray 200 is the second direction, and the width direction of the battery tray 200 is the third direction, or the length direction of the battery tray 200 is the third direction, and the width direction of the battery tray 200 is the second direction. The second direction is perpendicular to the third direction.

[0074] The sliding module may further include a first transmission unit (not shown), a second transmission unit (not shown) and a module control system, wherein the first transmission unit is connected to the first sliding component 12, and the module control system is electrically connected to the controller 30 and is used to control the first transmission unit to drive the first sliding component 12, the second sliding component 13, the glue coating head 2 and the profile scanner 20 to move together along the second direction under the control of the controller 30. The second transmission unit is connected to the second sliding component 13, and the module control system is also used to control the second transmission unit to drive the second sliding component 13, the glue coating head 2 and the profile scanner 20 to move together along the third direction under the control of the controller 30.

[0075] In this way, the controller 30 can control the sliding module to move along the second direction and / or along the third direction by controlling the working status of the first transmission unit and the second transmission unit, thereby driving the glue coating head 2 to apply glue to various areas on the glue coating surface of the battery tray 200, and driving the glue coating head 2 to scan various areas on the glue coating surface of the battery tray 200. Specifically, when applying glue, the controller 30 controls the first transmission unit to work, and controls the second transmission unit to stop working, so that the glue head 2 moves in the second direction and remains fixed in the third direction, thereby realizing continuous glue application to the battery tray 200 in the second direction; thereafter, the controller 30 controls the second transmission unit to work, and controls the first transmission unit to stop working, so that the glue head 2 moves a certain distance in the third direction; thereafter, the controller 30 controls the first transmission unit to work, and controls the second transmission unit to stop working, so that the glue head 2 moves in the second direction and remains fixed in the third direction, thereby realizing continuous glue application to the battery tray 200 in the second direction, and this cycle is repeated until the glue-coated surface of the battery tray 200 is fully coated with glue.

[0076] In other embodiments, the driving mechanism 1 may also be a robot, and the glue coating head 2 and the contour scanner 20 are fixedly mounted on the robot, and can be moved arbitrarily in three-dimensional space under the action of the robot.

[0077] The contour scanner 20 may be a laser scanner, which emits laser light to the glue-coated surface of the battery tray 200 , thereby obtaining point cloud data (ie, the first scanning data) related to the contour of the glue-coated surface.

[0078] In some embodiments, the contour scanner 20 is also used to scan the glue-coated surface of the battery tray 200 for a second time after the battery pack glue coating device 100 has coated the battery tray 200 with glue, so as to obtain second scanning data. The battery pack glue coating device 100 also includes a glue coating amount detection module 40, which is electrically connected to the contour scanner 20 and is used to perform comparative analysis based on the first scanning data and the second scanning data, and output corresponding comparative analysis results. The comparative analysis results are used to determine whether the amount of glue coating in each area on the glue-coated surface of the battery tray 200 is qualified.

[0079] In this way, on the one hand, the operator can adjust and repair the areas with unqualified glue coating on the glue coating surface of the battery tray 200 based on the comparative analysis results. On the other hand, the operator can also statistically analyze the comparative analysis results obtained from multiple gluing operations to adjust the correspondence between the initial flatness of the glue coating area and the target glue coating amount required for the area, thereby being able to control the glue coating amount more accurately.

[0080] Please also read Figure 3-4 , the following combination Figure 3 and Figure 4 The structure of the glue coating head 2 is introduced in detail.

[0081] The glue coating head 2 includes a glue feeding device 21 and a glue outlet pipe 22 connected to each other. The glue outlet pipe 22 is arranged along a first direction (such as Figure 2 The battery tray 200 is provided with a first nozzle 221 and a second nozzle 222 located at opposite ends in the first direction. The glue feeding device 21 is connected to the second nozzle 222 and is used to feed glue to the glue outlet pipe 22, so as to output the glue to the battery tray 200 through the first nozzle 221 of the glue outlet pipe 22. The first nozzle 221 is the glue outlet, and the second nozzle is the glue inlet.

[0082] Specifically, Figure 3 As shown, the glue feeding device 21 includes two sets of glue feeding components and a mixing valve 215. The mixing valve 215 includes two first interfaces and one second interface, the two first interfaces are connected to the two sets of glue feeding components one by one, and the second interface is connected to the second pipe opening of the glue outlet pipe 22. One set of glue feeding components is used to feed glue A to the mixing valve 215, and the other set of glue feeding components is used to feed glue B to the mixing valve 215.

[0083] Specifically, each set of glue delivery components includes a servo motor 211 , a reducer 212 , a coupling 213 and a screw pump 214 .

[0084] The servo motor 211 is electrically connected to the controller 30 and fixed to the reducer 212 . The central shaft (not shown) of the reducer 212 is connected to the screw in the screw pump 214 through the coupling 213 .

[0085] The connecting pipe between the screw pump 214 and the coupling 213 is provided with a glue inlet 2131 connected to a glue inlet pipe (not shown in the figure). During operation, the glue provided by the glue inlet pipe flows into the cavity (not shown in the figure) of the screw pump 214 through the glue inlet 2131. At this time, the servo motor 211 drives the reducer 212 to rotate, so that the reducer 212 drives the screw in the screw pump 214 to rotate through the coupling 213, thereby squeezing the glue in the cavity of the screw pump 214 into the mixing valve 215 for mixing, and then discharging through the first nozzle 221 of the glue outlet pipe 22, that is, the glue discharged from the first nozzle 221 of the glue outlet pipe 22 is the glue obtained by mixing glue A and glue B. Among them, the controller 30 can control the glue discharging speed of the glue coating head 2 by controlling the rotation speed of the servo motor 211 in the glue feeding device 21.

[0086] In some embodiments, the battery pack glue coating device 100 further includes a glue coating machine (not shown) and a glue coating machine control system (not shown), wherein the glue coating machine is connected to the glue inlet 2131 on the glue feeding device 21 through the glue feeding pipe, and is used to store glue A and glue B, and respectively drive glue A and glue B to be delivered to the glue feeding device 21. The glue coating machine control system is electrically connected to the controller 30, and is used to control the glue feeding speed (i.e., the glue feeding amount per unit time) of the glue coating machine to the glue feeding device 21, and / or control the glue feeding speed of the glue coating machine to deliver glue B to the glue feeding device 21, thereby adjusting the glue output speed of the glue coating head 2.

[0087] In some embodiments, the glue coating head 2 further includes a scraper 24, and the scraper 24 is disposed at the periphery of the first nozzle 221 of the glue outlet pipe 22. When the glue coating head 2 applies glue to the battery tray 200, the scraper 24 rotates around the axis of the glue outlet pipe 22 to scrape the glue on the glue coating surface of the battery tray 200.

[0088] In this way, while the glue outlet pipe 22 is discharging glue, the scraper 24 can scrape the glue discharged from the glue outlet pipe 22 onto the glue-coated surface of the battery tray 200, which can further improve the uniformity of glue coating and the flatness of the glue surface.

[0089] The first end of the scraper 24 is a flat end surface, and the plane where the first end of the scraper 24 is located is a plane perpendicular to the axis of the glue outlet pipe 22. The first end of the scraper 24 is the end away from the glue outlet pipe 22 in the first direction.

[0090] In some embodiments, the first end of the scraper 24 is located on the side of the first nozzle 221 of the glue outlet tube 22 away from the second nozzle in the first direction, that is, located below the first nozzle 221 of the glue outlet tube 22. Preferably, the plane where the first end of the scraper 24 is located is the preset glue coating reference plane. In this way, when coating, a certain gap is maintained between the first nozzle 221 of the glue outlet tube 22 and the preset glue coating reference plane, which is conducive to the smooth glue discharge of the glue outlet tube 22, thereby avoiding glue blockage, and the scraper 24 can scrape the glue in various areas on the glue coating surface of the battery tray 200 to be flush with the preset glue coating reference plane.

[0091] In some embodiments, the angle between the scraper blade 24 and the axis of the glue outlet pipe 22 is a first angle, and the first angle is greater than 0 degrees and less than 90 degrees. Figure 4 As shown, the scraper blade 24 is rectangular, the long side of the scraper blade 24 is perpendicular to the axis of the glue outlet pipe 22, and the angle between the short side of the scraper blade 24 and the axis of the glue outlet pipe 22 is a first angle.

[0092] In this way, a certain acute angle is formed between the scraper blade 24 and the axis of the glue outlet pipe 22, so that the glue scraping is smoother.

[0093] In some embodiments, the glue coating head 2 further includes an evacuation sheet 25, which is disposed between the glue outlet pipe 22 and the scraper 24. When the glue coating head 2 is coating the battery tray 200 with glue, the evacuation sheet 25 rotates around the axis of the glue outlet pipe 22 to evacuate the glue accumulated on the coating surface of the battery tray 200.

[0094] When applying glue, the first nozzle 221 of the glue outlet pipe 22 outputs glue to the glue-coated surface of the battery tray 200. Since the evacuation sheet 25 is arranged between the glue outlet pipe 22 and the scraper 24, as the glue coating head moves, the evacuation sheet 25 first evacuates the glue accumulated on the glue-coated surface of the battery tray 200, and then the scraper 24 scrapes the evacuated glue flat. In this way, the flatness of the glue surface can be further improved.

[0095] The first end of the evacuation sheet 25 is in a sawtooth or wave shape, and the first end of the evacuation sheet 25 is an end away from the rubber outlet pipe 22 in the first direction.

[0096] In some embodiments, the angle between the evacuation sheet 25 and the axis of the glue outlet pipe 22 is a second angle, the second angle is greater than 0 degrees and less than 90 degrees, and the first angle is greater than the second angle.

[0097] like Figure 4 As shown, in some embodiments, the first end of the evacuation sheet 25 is located between the first end of the scraper 24 and the first nozzle 221 of the glue outlet pipe 22 in the first direction, that is, the first end of the evacuation sheet 25 is located above the preset glue coating reference plane, so that the already flat glue surface can be prevented from being evacuated again by the evacuation sheet 25. In other embodiments, the first end of the evacuation sheet 25 can also be flush with the first end of the scraper 24 in the first direction.

[0098] In some embodiments, the glue coating head 2 further includes a rotating device 23 , and the rotating device 23 includes a rotating device body 231 , a stator (not shown) and a rotor 232 .

[0099] Exemplarily, the rotating device 23 is a hollow motor.

[0100] The rotating device body 231 is fixedly connected to the glue feeding device 21, and the stator is fixedly mounted on the rotating device body 231. The rotor 232 is arranged inside the stator and surrounds the outer periphery of the glue outlet pipe 22, and can rotate around the glue outlet pipe 22. The scraper 24 and the evacuation sheet 25 are both connected to the rotor 232, and can rotate around the glue outlet pipe 22 together under the drive of the rotor 232.
