[0002] The liquid cooling plate of the battery pack usually needs to be connected to the battery pack housing. Depending on the connection method, the edges often do not require an insulating coating, which means that masking is required before insulating spraying. Masking tape should be applied to the sides.

[0003] Currently, masking tape application is done manually. Manual masking involves several steps: first, marking lines on a tooling panel on the cold-rolled steel sheet for positioning; then, tearing off the masking tape; finally, applying the tape; and finally, cutting the tape. This process carries risks such as low application accuracy, uneven application, and weak local adhesion. Utility Model Content

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] Example

[0028] like Figure 1-7 As shown, an automatic masking device is characterized by: including a lower support 1, with a rotating mechanism 3 on its end face, and a rolling mechanism 2 and a masking mechanism 4 respectively on both sides of the rotating mechanism 3;

[0029] The lower support 1 is composed of the frame body 1-1 and the first mounting plate 1-3 on its end face;

[0030] The unwinding mechanism 2 comprises a second mounting plate 2-1, a linear module 2-2, a winding reel 2-3, a pressure roller assembly 2-4, and a clamping roller 2-5.

[0031] The rotating mechanism 3 includes a worktable 3-1, a fixed positioning pin 3-2, a cylinder clamping block 3-3, a roller 3-4, and a rotating power assembly 3-5;

[0032] The masking mechanism 4 includes a horizontal linear module 4-1, a vertical linear module 4-2, a pressure roller mechanism 4-3, a tape clamping mechanism 4-4, and a cutting mechanism 4-5.

[0033] In this embodiment, the lower end of the frame body 1-1 is provided with multiple adjustable feet 1-2.

[0034] The second mounting plate 2-1 is slidably connected to the linear module 2-2, and the winding reel 2-3, pressure roller assembly 2-4 and clamping roller 2-5 are sequentially arranged on one side of the second mounting plate 2-1.

[0035] The upper end of the clamping wheel 2-5 is provided with a telescopic cylinder 2-6 connected to it, and multiple rollers are provided on one side of the second mounting plate 2-1 between the winding disc 2-3, the pressure roller assembly 2-4 and the clamping wheel 2-5.

[0036] There are multiple cylinder clamping blocks 3-3, which are arranged around the worktable 3-1. Fixed positioning pins 3-2 are equidistantly and symmetrically arranged on the end face of the worktable 3-1.

[0037] At least two rollers 3-4 are provided, both of which are located on the bottom surface of the worktable 3-1. The rotational power assembly 3-5 is located between the two rollers 3-4 and consists of a drive motor, coupling, bearing seat and rotating shaft.

[0038] The longitudinal linear module 4-2 is positioned above the transverse linear module 4-1 and is movably connected to it.

[0039] The longitudinal linear module 4-2 is provided with a fixed plate 4-6 that is movably connected to it. The tape clamping mechanism 4-4 and the cutting mechanism 4-5 are respectively located on the top and one side of the fixed plate 4-6.

[0040] Lower Support: As the supporting component of the entire equipment and the housing device for the electrical control system, the lower support plays a very important role in the entire equipment. To ensure that the frame body can effectively support the entire equipment system, it is made of 50# square tube and welded together. There is one adjustable foot at the bottom of each column, which is used to level the lower support and the entire equipment. There are three mounting plates, which provide mounting platforms for the unwinding mechanism, the masking mechanism and the rotating mechanism.

[0041] Unwinding Mechanism: The main function of the unwinding mechanism is to unwind the tape from the tape roll in a sequential manner, ensuring it is used immediately without confusion. The mounting plate serves as the base for all functional components, which are then mounted on it. The winding reel is the mounting plate for shielding the tape roll, which is then mounted on it. The tape wraps around the pressure roller assembly, allowing it to unwind in a preset direction. The middle roller is a gravity-type pressure roller that tauts the tape and provides damping. The clamping roller, located at the front of the unwinding mechanism, works with the cylinder pressure roller to clamp the tape between the rollers, preventing relative sliding and only providing a rolling action. The linear module provides the power for the unwinding mechanism to move back and forth, adjusting its position to align the tape with the cold plate.

[0042] Rotation mechanism: Since cold plates are mostly rectangular in shape, and the masking is often attached to the four edges of the cold plate, and the tape travels in one direction, a rotation mechanism is needed to adjust the orientation of the cold plate. The cold plate is placed on the worktable and positioned and clamped by fixed positioning pins and cylinder clamping blocks. It rotates under the drive of the rotation power assembly (one station every 90°).

[0043] Masking mechanism: The masking mechanism is the core component of the equipment. The horizontal linear module and the vertical linear module form the horizontal and vertical drive components of the working head. The working head includes a pressure roller mechanism, a tape clamping mechanism and a cutting mechanism, which are responsible for pressing, clamping and cutting the tape, respectively.

[0044] Operating procedure: First, place the cold plate workpiece on the workbench and initially position it with a fixed positioning block. Then, activate the cylinder clamping block to fully position the workpiece. The roll of masking tape is fixed on the winding reel. After the tape passes through the pressure roller assembly and clamping roller, it is clamped by the tape clamping mechanism.

[0045] After the equipment is started, the tape clamping mechanism pulls the masking tape to the very edge of the cold plate. The pressure roller mechanism presses down and simultaneously releases the tape clamping mechanism. The masking mechanism moves to the left and presses the masking tape onto the cold plate. After one side is finished, the pressure roller mechanism lifts up, the tape clamping mechanism clamps the tape, and at the same time, the cutting mechanism cuts down to remove the tape. Driven by the rotating mechanism, the workpiece rotates 90° and the masking process is repeated.

[0046] The pressure roller assembly includes a set of gravity pressure rollers and clamping rollers to ensure the tension of the conveyor belt and prevent relative slippage. When the pressure roller passes the cylinder clamping block, the cylinder retracts, allowing the pressure roller mechanism to pass smoothly. After the pressure roller mechanism passes, the cylinder clamping block returns to its position and clamps.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
