The embodiment of the utility model provides a coating device and a coating machine, which are used for solving the technical problem of low coating efficiency of the coating machine.

In the embodiment of the utility model, as shown in fig. 1 and 2, the coating device comprises a support 1, a tensioning roller 2, a first driver, a first pressing plate 3, a conveying mechanism 4, a film drawing component 5 and a first cutting component 6, wherein the tensioning roller 2, the first driver, the film drawing component 5 and the first cutting component 6 are all arranged on the support 1; the tensioning roller 2 is used for tensioning the film strip; the first pressing plate 3 is connected with the output end of a first driver, and the first driver is used for driving the first pressing plate 3 to press the film belt against the support 1 or driving the first pressing plate 3 to be far away from the support 1; the conveying mechanism 4 is arranged through the support 1 and is used for conveying the piece 50 to be coated along the first direction; the film pulling assembly 5 can be close to or far away from the first pressing plate 3 along the second direction, so as to drive the film strip to pass over the conveying mechanism 4; the first cutting assembly 6 is movable in a third direction to sever the film strip between the transport mechanism 4 and the first platen 3; wherein the first direction, the second direction and the third direction are perpendicular to each other.

As shown in fig. 1, the x-direction is parallel to the conveying direction of the conveying mechanism 4, i.e., the x-direction is parallel to the first direction; the y-direction is parallel to the axial direction of the tensioning roller 2, i.e. the y-direction is parallel to the third direction; the z-direction is parallel to the vertical direction, i.e. the z-direction is parallel to the second direction. Wherein the x direction, the y direction and the z direction are perpendicular to each other.

In this embodiment, the film strip may be a blue film strip, and the member to be coated 50 may be a battery, so as to cover the blue film on the surface of the battery, thereby protecting the battery through the blue film. The film strip is stretched by the stretching roller 2, passes through the space between the first pressing plate 3 and the support 1, and is propped against the support 1 by the first pressing plate 3.

The tension roller 2 may be provided in plural to tension the film tape by the tension roller 2.

When the first driver drives the first pressing plate 3 to be close to the support 1, the film strip can be propped against the support 1 through the first pressing plate 3, so that the film strip is prevented from being separated from the original position due to vibration, unexpected applied external force and the like. When the first driver drives the first pressing plate 3 to be far away from the support 1, the first pressing plate 3 can be driven to loosen the film strip, so that the film pulling component 5 can continue to pull the film along the second direction.

The conveying mechanism 4 is arranged through the support 1, so that the film pulling assembly 5 moves towards the first pressing plate 3 along the second direction during film coating, and the film pulling assembly 5 is fixed with the tail end of the film strip. At this time, the first pressing plate 3 presses the membrane strip against the support 1 and leaves the tail end of the membrane strip, so that the first pressing plate 3 avoids the tail end of the membrane strip, and the membrane pulling assembly 5 and the tail end of the membrane strip are conveniently fixed together. The first pressure plate 3 is then driven away from the support 1 by the first driver mechanism so that the first pressure plate 3 releases the film strip. The film strip is driven to move along the second direction by the film pulling assembly 5, and the film strip passes through the conveying mechanism 4. After the membrane pulling assembly 5 stretches the membrane strip by a preset length, the first driver drives the first pressing plate 3 to press the membrane strip against the support 1. When the piece 50 to be coated is conveyed along the first direction by the conveying mechanism 4, the piece 50 to be coated can drive the film strip to continue to move along the first direction, and as one end of the film strip is pressed against the support 1 by the first pressing plate 3, the other end of the film strip is fixed on the film pulling assembly 5, namely, two ends of the film strip are respectively fixed, the two ends of the film strip are fixed at the position of the first direction, and the middle position of the film strip can move along the first direction along with the piece 50 to be coated, so that the film strip is coated on the surface of the piece 50 to be coated, and the film coating of the piece 50 to be coated is realized. When the film strip is driven by the film-coating member 50 to move along the first direction, the film pulling assembly 5 can move towards the conveying mechanism 4, so that the film strip can be driven by the film-coating member 50, and coating can be conveniently realized.

It will be appreciated that the film pulling module 5 may be fixed to the end of the film strip by adsorption, or may be adhered to the film pulling module 5 by an adhesive layer of the film strip itself, which is not limited herein.

After the film coating is completed, the first cutting assembly 6 can be pressed against the film strip between the conveying mechanism 4 and the first pressing plate 3, and then the first cutting assembly 6 is moved along the third direction so as to cut off the film strip, so that the film coating of the piece 50 to be coated is realized.

The first driver of the embodiment of the utility model is arranged on the support 1, and can drive the first pressing plate 3 to press the film strip against the support 1 when the film strip is driven by the film strip to be coated 50 on the conveying mechanism 4 to move along the first direction so as to carry out coating and when the film strip is cut by the first cutting assembly 6, so that the tail end of the film strip is prevented from being separated from the original position; when the film pulling assembly 5 is fixed with the tail end of the film belt to pull the film, the first driver can drive the first pressing plate 3 to be far away from the support 1 so as to loosen the film belt; because the film strip can be propped against through the first pressing plate 3, the tail end of the film strip is prevented from being separated from the original position, and therefore, when the film is pulled every time, the film pulling component 5 can move to the same position to be fixed with the tail end of the film strip for film pulling, the frequency of searching the tail end position of the film strip is reduced, namely, the frequency of unexpected occurrence is reduced, and the film coating efficiency is improved.
