wherein the coater comprises a coating head and a coating head movement mechanism, the coating head movement mechanism is configured to make the coating head move along a plane intersected with the first direction and rotate in the plane intersected with the first direction,
the coating head movement mechanism is configured to make the coating head move along a second direction perpendicular to the coating platform,
the coating head movement mechanism comprises: a first propulsion mechanism, configured to make the coating head move along the second direction; and a rotating structure, configured to make the coating head rotate in a plane perpendicular to the first direction,
the rotating structure comprises: a driving motor, comprising an output shaft configured to rotate around an axis parallel to the first direction; a coating head shaft, fixed with the coating head, wherein an axis direction of the coating head shaft is the first direction; and a driving belt, wherein the driving belt is connected with the output shaft and the coating head shaft.

2. The coating apparatus according to claim 1 , further comprising: a transport mechanism and/or a coating platform, wherein the transport mechanism is configured to transport an object to be coated, and the coating platform is configured to support the object to be coated, the first direction is parallel to a plane where the coating platform is located.

3. The coating apparatus according to claim 2 , wherein the coating head movement mechanism is configured to make the coating head rotate in a plane perpendicular to the first direction.

4. The coating apparatus according to claim 3 , wherein the transport mechanism is configured to move along the first direction and the second direction.

5. The coating apparatus according to claim 3 , wherein the transport mechanism comprises:
a first transport guide rail, extending along the first direction, wherein the transport mechanism is configured to move along the first direction through the first transport guide rail; and
a second transport guide rail, extending along the second direction, wherein the transport mechanism is configured to move along the second direction through the second transport guide rail.

6. The coating apparatus according to claim 3 , wherein the coating platform is configured to move along the first direction and a third direction which is perpendicular to the first direction and the second direction and rotate in a plane perpendicular to the second direction.

7. The coating apparatus according to claim 6 , wherein the coating platform comprises:
a first coating guide rail, extending along the first direction, wherein the coating platform is configured to move along the first direction through the first coating guide rail;
a second coating guide rail, extending along the third direction, wherein the coating platform is configured to move along the third direction through the second coating guide rail; and
a rotation part configured to make the coating platform rotate in the plane perpendicular to the second direction.

8. The coating apparatus according to claim 6 , wherein a rotating angle of the coating platform in the plane perpendicular to the second direction has a rotating range of 0°-360°.

9. The coating apparatus according to claim 2 , wherein the transport mechanism comprises a first sub transport mechanism and a second sub transport mechanism, the first sub transport mechanism is configured to move the object to be coated to the coating platform, the second sub transport mechanism is configured to move the object to be coated out of the coating platform.

10. The coating apparatus according to claim 1 , further comprising:
a second propulsion mechanism, comprising a first guide rail,
wherein the first guide rail is extending along the first direction, the coater is disposed on the first guide rail, and the first propulsion mechanism is configured to make the coater move along the first direction.

11. The coating apparatus according to claim 1 , wherein the rotating structure further comprises:
a fixing portion, wherein the output shaft and the coating head shaft are respectively disposed at two ends of the fixing portion, so as to fix the relative position between the output shaft and the coating head shaft.

12. The coating apparatus according to claim 1 , further comprising:
a curing lamp, wherein the curing lamp and the coating head are sequentially disposed along the first direction, and the curing lamp is configured to cure liquid curable adhesive coated by the coating head.

13. The coating apparatus according to claim 12 , wherein the curing lamp is fixed to the coating head shaft, and the output shaft drives the curing lamp to rotate in a plane perpendicular to the first direction through the driving belt and the coating head shaft.
