As shown in fig. 1, the glue reservoir 1 is an open channel, and comprises only a circumferential side wall 101 and a bottom wall 102. Alternatively, the opening of the tank body may be provided with a cover body in a sealing manner. Whether the glue storage piece 1 is open or not can be determined according to the convenience degree of operation, and the type of glue solution can be specifically selected.
The glue storage piece 1 has no supporting structure, and can be directly placed above the battery module when in use, namely, a plurality of batteries in the module support the glue storage piece 1, and the self weight of the glue storage piece 1 and glue solution is utilized to press and cover the battery module, so that the glue injection position corresponding to the batteries is ensured to be relatively fixed. Alternatively, a frame may be provided to fix the height of the glue reservoir 1, or the height of the glue reservoir 1 may be adjusted by a lifting mechanism.
The arrangement mode of the rubber outlet pipes 4 is determined according to the arrangement of the batteries in the module, and the number of the rubber outlet pipes 4 depends on the rubber injection positions. It will be appreciated that the number of outlet tubes 4 is equal to or greater than the number of batteries in the module. The rubber outlet pipes 4 are arranged in a rectangular array in fig. 2.
The glue pressing member 2 moves in a direction approaching or separating from the bottom wall 102, and in fig. 1, the glue outlet direction is the vertical direction, so the moving direction of the glue pressing member 2 may be alternatively the plumb direction. The glue pressing piece 2 descends, downward pressure is applied to glue solution in the glue cavity, and the glue solution is discharged through the glue outlet pipe 4; when the liquid level of the glue solution in the glue cavity is lowered to a preset height, the glue pressing piece 2 is lifted to be separated from the glue storage piece 1, and the glue solution is fed into the glue cavity.
Instead, a glue injection port for injecting glue into the glue cavity is arranged on the bottom wall 102 or the side wall, and the upward speed of the glue pressing piece 2 is controlled to be matched with the glue injection so as to ensure that the glue pressure in the glue cavity does not cause the glue to be discharged from the glue outlet pipe 4, thereby realizing the glue filling into the glue cavity.
The glue discharging mechanism 5 is a linear driving mechanism, which can be selected as a manual or automatic mechanism, wherein the linear driving mechanism comprises, but is not limited to, a cylinder, a hydraulic cylinder and a linear sliding table, and the linear driving mechanism is specifically determined according to the load and the stroke of the glue pressing piece 2, and is preferably a linear driving mechanism with higher stroke control precision, so that the total glue discharging amount of the plurality of glue discharging pipes 4 is more accurate.

The glue solution can be selected from structural glue or heat-conducting glue, such as AB two-component heat-conducting glue. In the actual glue injection process, the inner diameter of the glue outlet pipe 4 is smaller, and the bi-component heat-conducting glue has certain viscosity at the preset glue injection temperature, so that the gravity glue is not easy to discharge from the glue outlet pipe 4, and the glue injection is based on the pressure of the glue pressing piece 2.

When the glue storage part 1 is pressed on the battery module or fixed on the frame, the position of the glue storage part 1 is fixed, the glue pressing part 2 is propped against the inner surface of the circumferential side wall 101, and the screw 501 rotates, the glue pressing part 2 only moves along the axial direction of the screw 501, the axial direction of the screw 501 is consistent with the plumb direction in fig. 1, the screw 501 drives the glue pressing part 2 to move along the plumb direction, the glue pressing part 2 pushes glue solution, and the glue solution is discharged through the glue outlet pipe 4. Further, after the screw rod 501 is driven to rotate forward and the glue pressing member 2 is driven to move downward for discharging glue, the screw rod 501 can be further driven to rotate reversely, so that the glue pressing member 2 moves upward in a micro way, and the glue in the glue outlet pipe 4 is accelerated to be separated from the discharged glue.
Compared with linear driving parts such as a cylinder and a hydraulic cylinder, the positioning precision of the screw rod 501 is higher, the influence of the weight of the glue storage part 1 and glue solution on the screw rod 501 glue discharging mechanism 5 is smaller, and the stroke of the glue pressing part 2 is determined by the rotation angle of the screw rod 501 or the height of the preset position of the screw rod 501, so that the visualization is more realized.
Optionally, the supporting seat 3 comprises a supporting seat main body and a first bearing, the optical axis section of the screw rod 501 is tightly matched with the inner ring of the first bearing, the outer ring of the first bearing is fixedly connected with the supporting seat main body, the relative position between the screw rod 501 and the supporting seat 3 before and after rotation is unchanged, and the resistance for driving the screw rod 501 to rotate is reduced.
