[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , the present invention provides a technical solution: a glue coating device for a battery pack liquid cooling plate with uniform scraping, including a base 1, a box body 2, a suction cup 3, a connecting pipe 4, a micro air pump 5, a top rod 6, a spring 7, a support column 8, a rack 9, a gear 10, a pressure roller 11, a support frame 12, a glue spray head 13, an electric push rod 14, and a connecting rod 15.

[0031] The base 1 is a long plate structure, and the box body 2 is penetrated through the surface of the base 1. The box body 2 is a hollow structure, and an adsorption and fixation structure is arranged inside the box body 2. The adsorption and fixation structure sets the suction cup 3 to adsorb and fix the liquid cooling plate from below. The adsorption and fixation structure includes the box body 2. A cylindrical groove is annularly arranged on the upper surface of the box body 2. The suction cup 3 is arranged in the groove on the surface of the box body 2. The lower surface of the suction cup 3 is connected with a connecting pipe 4. The other end of the connecting pipe 4 penetrates the bottom surface of the groove on the surface of the box body 2, and the connecting pipe 4 is fixedly connected with the surface of the box body 2. The micro air pump 5 is fixedly installed on the lower surface of the base 1, and the micro air pump 5 is connected to the micro air pump 5;

[0032] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, when using this device, insert the liquid cooling plate between the base 1 and the pressure roller 11 so that the liquid cooling plate is located at the box body 2 on the surface of the base 1. At this time, the lower surface of the liquid cooling plate contacts the upper surface of the suction cup 3. Start the micro air pump 5. The micro air pump 5 pumps out the air inside the suction cup 3 through the connecting pipe 4, so that the pressure inside the suction cup 3 is less than the atmospheric pressure. The suction cup 3 tightly fits with the lower surface of the liquid cooling plate. Also, because the connecting pipe 4 is fixedly connected with the surface of the box body 2, the liquid cooling plate tightly fits with the surface of the box body 2 under the action of the suction cup 3, preventing the displacement of the liquid cooling plate during the glue coating process.

[0033] A top material structure is arranged on the surface of the base 1. The top material structure sets the top rod 6 to eject the liquid cooling plate after glue coating. The top material structure includes the top rod 6. One end of the top rod 6 is installed in the groove on the surface of the base 1. The top rod 6 is a telescopic structure, and one end of the top rod 6 extends out of the surface of the base 1. A spring 7 is arranged on the outer surface of the top rod 6. One end of the spring 7 is connected to the top rod 6, and the other end of the spring 7 is connected to the inner wall of the base 1;

[0034] As Figure 1 ,Figure 3 and Figure 4 As shown in Figure 4 , when the liquid cooling plate is attached to the box body 2 on the surface of the base 1, the liquid cooling plate pushes the ejector rod 6 downward, the ejector rod 6 is compressed, driving the spring 7 to be compressed. After the glue application is completed, the micro air pump 5 stops pumping air, the liquid cooling plate loses the pressure on the ejector rod 6, and the ejector rod 6 rebounds under the action of the spring 7, causing the ejector rod 6 to push the liquid cooling plate upward to facilitate the blanking of the liquid cooling plate.

[0035] A glue application structure is provided on the upper surface of the base 1. The glue application structure sets the synchronous movement of the pressure roller 11 and the glue spray head 13 to realize the glue application and leveling process. The glue application structure includes support columns 8. The support columns 8 are fixedly installed on the upper surface of the base 1. The support columns 8 are in the shape of H. Two support columns 8 are symmetrically arranged on the upper surface of the base 1. A rack 9 is arranged between the two support columns 8. There are two symmetrically arranged racks 9. A gear 10 is meshed on the upper surface of the rack 9. The two gears 10 are connected to the surface of the same rotating shaft. A pressure roller 11 is arranged on the outer surface of the rotating shaft of the gear 10. The outer surface of the rotating shaft of the gear 10 is rotatably connected to the support frame 12. The support frame 12 is two connected circular ring structures. A plurality of glue spray heads 13 are arranged on one side of the support frame 12. The upper ends of the glue spray heads 13 are connected by hoses. A valve is arranged inside the glue spray head 13 to control the opening and closing. An electric push rod 14 is fixedly installed on the upper surface of the support column 8. The output end of the electric push rod 14 is provided with a connecting rod 15. The other end of the connecting rod 15 is fixed on the surface of the support frame 12. The connecting rod 15 is a telescopic structure;

[0036] As Figure 1 、 Figure 5 and Figure 6 shown, after the liquid cooling plate is adsorbed and fixed on the surface of the box body 2, the hose at the upper end of the glue spray head 13 is connected to the thermal conductive glue, and the electric push rod 14 is started. The electric push rod 14 drives the connecting rod 15 to move, so that the connecting rod 15 drives the support frame 12 to move, and the support frame 12 drives the pressure roller 11 to move. When the pressure roller 11 moves, the gears 10 at both ends of the pressure roller 11 rotate under the action of the rack 9, driving the pressure roller 11 to rotate. When the pressure roller 11 rotates and slides, the valve inside the glue spray head 13 is started, so that the thermal conductive glue falls from the glue spray head 13 to the surface of the liquid cooling plate below. At this time, the rotating pressure roller 11 evenly scrapes the thermal conductive glue on the surface of the liquid cooling plate, thus realizing the glue application process of the liquid cooling plate. By controlling the valve in the glue spray head 13, the quantitative extrusion of the thermal conductive glue can be realized. Since the glue spray head 13 moves synchronously with the support frame 12, the glue extruded by the glue spray head 13 can be almost simultaneously scraped flat by the pressure roller 11.

[0037] Working principle: When using the glue coating device for the battery pack liquid cooling plate with uniform scraping, place the liquid cooling plate in the box body 2 on the surface of the base 1, start the micro air pump 5, the micro air pump 5 evacuates the suction cup 3 through the connecting pipe 4, so that the suction cup 3 adsorbs to the lower surface of the liquid cooling plate, preventing the displacement of the liquid cooling plate while not affecting the coating of the thermal conductive glue on the upper surface. When the liquid cooling plate is adsorbed and fixed by the suction cup 3, it will compress the ejector rod 6 downward. After the glue coating is completed, the liquid cooling plate is lifted upward under the action of the spring 7 and the ejector rod 6, facilitating the feeding. A pressure roller 11 is arranged on the upper surface of the base 1. Start the electric push rod 14, the electric push rod 14 drives the connecting rod 15 to move, thereby driving the support frame 12 and the pressure roller 11 to move. A glue spray head 13 is arranged on one side of the support frame 12, realizing the synchronous operation of the glue extrusion and the pressure roller 11. The gears 10 at both ends of the pressure roller 11 are engaged with the rack 9. When the pressure roller 11 moves left and right, it will rotate under the action of the rack 9, uniformly coating the thermal conductive glue, increasing the overall practicability.

The scope of the present invention is defined by the appended claims and their equivalents.
