[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 The utility model provides a technical solution: a battery pack liquid cooling plate gluing device, including a base 1, a conveyor belt 2, a support plate 3, a supporting plate 4, a sliding block 5, a nozzle 6, an electric push rod 7, a support platform 8, a connecting pipe 9, a delivery pipe 10, a baffle 11, and a hose 12.

[0032] The top surface of base 1 is provided with conveyor belt 2, and conveyor belt 2 is symmetrically provided with two, and two conveyor belts 2 are connected to the surface of the same set of driving rollers, and support plates 3 are fixedly installed on the two side surfaces of base 1 respectively, and a supporting plate 4 is provided between the two supporting plates 3. The supporting plate 4 is a hollow square frame structure, and the inner wall of supporting plate 4 is symmetrically provided with a slide groove, and the slide groove surface of the inner wall of supporting plate 4 is also provided with a sliding block 5. The surface of sliding block 5 is penetrated by nozzle 6. The two side surfaces of sliding block 5 are provided with a runner that contacts the slide groove of the inner wall of supporting plate 4, and the interior of sliding block 5 is provided with a control mechanism to control the movement of the runner. The surface of nozzle 6 is provided with a height adjustment structure, and the height adjustment structure is provided with an electric push rod 7 to realize the height adjustment of nozzle 6. The height adjustment structure includes an electric push rod 7, which is fixedly mounted between the two support plates 3 by a bracket, and the output end of the electric push rod 7 is fixedly connected to the upper surface of supporting plate 4 by a bracket, and the two ends of supporting plate 4 are respectively slidably connected to the support plates 3 on both sides;

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, when using this device, the nozzle 6 is connected to the external thermal conductive glue conveying mechanism so that the thermal conductive glue is sprayed from the nozzle 6, and the control mechanism inside the sliding block 5 is started to make the wheel on the surface of the sliding block 5 slide back and forth in the slide groove on the inner wall of the supporting plate 4, and the liquid cooling plate to be coated with glue is placed on the surface of the conveyor belt 2, and the conveyor belt 2 is started. The conveyor belt 2 drives the liquid cooling plate to move. When the liquid cooling plate moves to the bottom of the nozzle 6, the surface of the liquid cooling plate is coated with glue under the action of the reciprocating nozzle 6, and since the liquid cooling plate continues to move with the conveyor belt 2, the moving liquid cooling plate is coated with glue under the reciprocating nozzle 6, and the electric push rod 7 is started. The electric push rod 7 drives the supporting plate 4 to slide up and down on the surface of the support plate 3, and the height of the nozzle 6 can be adjusted, thereby changing the distance between the nozzle 6 and the liquid cooling plate, which is convenient for adjusting the range of glue spraying.

[0034] An adsorption structure is provided between the two conveyor belts 2. The adsorption structure utilizes the through holes on the surface of the support platform 8 to connect with the external negative pressure fan to realize the adsorption and clamping of the liquid cooling plate during the gluing process from below. The adsorption structure includes a support platform 8, which is fixedly mounted on the upper surface of the base 1, and the support platform 8 is located between the conveyor belts 2 on both sides. The support platform 8 is a hollow square box structure, and the upper surface of the support platform 8 is flush with the surface of the conveyor belt 2. A plurality of square through holes are equidistantly provided on the surface of the support platform 8. A connecting pipe 9 is fixedly installed on the inner wall of the square through hole on the surface of the support platform 8. The connecting pipe 9 is a hollow rectangular parallelepiped structure with an open upper surface, and the lower surface of the connecting pipe 9 is penetrated by a hole. There is a conveying pipe 10, the ends of multiple conveying pipes 10 are connected to each other, a shielding structure is provided on one side of the conveying pipe 10, and a rotating baffle 11 is provided on the shielding structure to realize intermittent penetration of the conveying pipe 10. The shielding structure includes a baffle 11, which is rotatably connected to the inner wall of the support platform 8, and the baffle 11 is a circular plate structure with a circular air outlet provided on the surface. The rotating shaft of the baffle 11 passes through the surface of the support platform 8 and is connected to the drive shaft of the conveyor belt 2 through a transmission chain. One side surface of the baffle 11 contacts the end of the conveying pipe 10, and the other side surface of the baffle 11 contacts the hose 12. The hose 12 is provided through the surface of the support platform 8, and the hose 12 is aligned with the conveying pipe 10;

[0035] like Figure 1 、 Figure 5 、 Figure 6 and Figure 7 As shown, the hose 12 is connected to a negative pressure fan. When the device is running, the negative pressure fan is started to extract air from the air duct formed by the connecting pipe 9, the delivery pipe 10 and the hose 12, so that a negative pressure is formed on the surface of the support platform 8. When the liquid cooling plate moves on the surface of the conveyor belt 2, the lower surface of the liquid cooling plate slides over the surface of the support platform 8 at the same height as the conveyor belt 2. When the liquid cooling plate contacts the upper surface of the support platform 8, the negative pressure formed at the connecting pipe 9 on the surface of the support platform 8 adsorbs the liquid cooling plate under the liquid cooling plate, thereby increasing the stability of the liquid cooling plate during the gluing process. When the conveyor belt 2 is started, the driving roller of the conveyor belt 2 continuously drives the baffle 11 inside the support platform 8 to rotate. The rotating baffle 11 causes the air outlet on the surface to continuously open and block the end of the delivery pipe 10, so that the delivery pipe 10 and the hose 12 are intermittently connected and disconnected, thereby forming an intermittent negative pressure on the surface of the support platform 8. Without affecting the movement of the liquid cooling plate, the movement speed of the liquid cooling plate on the surface of the conveyor belt 2 is slowed down without affecting the movement of the liquid cooling plate.

[0036] Working principle: When using the battery pack liquid cooling plate gluing equipment, the nozzle 6 is connected to the thermal conductive glue, and the control mechanism inside the sliding block 5 is started. The sliding block 5 drives the nozzle 6 to slide back and forth in the slide groove on the inner wall of the support plate 4, and the liquid cooling plate is placed on the surface of the conveyor belt 2. The liquid cooling plate moves under the nozzle 6 along with the conveyor belt 2. Under the action of the reciprocating sliding nozzle 6, the surface of the liquid cooling plate is coated with glue. The hose 12 is externally connected to the negative pressure fan, and the negative pressure fan is started to form a negative pressure on the surface of the support platform 8, and the liquid cooling plate is adsorbed under the liquid cooling plate to increase the stability of the liquid cooling plate during the gluing process. The baffle 11 rotates continuously with the driving roller of the conveyor belt 2. The rotating baffle 11 causes the end of the conveying pipe 10 to open and close intermittently, thereby forming intermittent negative pressure on the surface of the support platform 8, slowing down the movement speed of the liquid cooling plate on the surface of the conveyor belt 2 without affecting the movement of the liquid cooling plate, thereby increasing the overall practicality.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
