[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] Example 1

[0031] Reference Figure 1As shown, the utility model discloses a rotatable coating head, comprising: a rotary drive source 1, a coupling 2 and a coating head 3, wherein: the output end of the rotary drive source 1 is connected to the coupling 2, the coupling 2 is driven to rotate by the rotary drive source 1, and the coating head 3 is arranged on the coupling 2, and the rotary drive source 1 drives the coating head 3 to rotate at a fixed angle through the coupling 2, so that the coating head 3 can rotate at least in three stations, including: a working station 11, a maintenance station 12 and a bubble removal station 13, when the coating head 3 moves to the working station 11, the coating head 3 can be used normally, when the coating head 3 moves to the maintenance station 12, it is convenient to maintain the coating head 3 online, to inspect and clean the coating head 3, and when the coating head 3 moves to the bubble removal station 13, it is convenient to discharge the air inside the cavity of the coating head 3, thereby improving the product yield.

[0032] Reference Figure 1 As shown, when the coating head 3 rotates to the point where the lip is perpendicular to the upper surface of the coating platform and the lip is facing the coating platform, the coating head 3 is located at the working station 11, and an external transfer device is provided to drive the coating head 3 to contact the coating platform, and then drive the coating head 3 to perform reciprocating motion along the X-axis or Y-axis on a horizontal plane to achieve coating work of the coating head 3.

[0033] Reference Figure 2 As shown, after the coating head 3 is driven by the rotary drive source 1 to rotate upward 90°, the coating head 3 is rotated until the lip is parallel to the upper surface of the coating platform, and the coating head 3 is located at the maintenance station 12. The operator can use a tool to open the lip on the coating head 3 to clean the inner surface of the coating head 3, and can also inspect and maintain the coating head 3.

[0034] Reference Figure 3 As shown, during the preparation process, a large amount of air is generated because the upper liquid pump pushes the coating liquid to move toward the pipeline and the coating cavity. When the lip is downward, the air is upward, resulting in the inability to completely discharge the air in the cavity. After the coating head 3 is driven by the rotary drive source 1 to rotate upward 180°, the coating head 3 is rotated until the lip is perpendicular to the upper surface of the coating platform and the lip is away from the coating platform. At this time, the coating head 3 is located at the bubble discharge station 13 and starts to discharge liquid and bubbles until the coating liquid flows out of the lip to complete this work, and then it is driven by the rotary drive source 1 to rotate to the working station 11 to start the coating work.

[0035] Specifically, after the coating head 3 rotates to different workstations, the position of the coating head 3 needs to be fixed to prevent the coating head 3 from swinging under the action of external force, causing the coating head 3 to rotate in other directions, thereby failing to complete the corresponding work task. Therefore, in this embodiment, a locking mechanism is also provided, and the locking mechanism can fix the position of the coating head 3 when the coating head 3 moves to different workstations;

[0036] Reference Figure 1 to Figure 3 As shown, the mold locking mechanism includes: a mold locking drive source 4, a latch 5 and a pin hole 6 matched with the latch 5, wherein: the mold locking drive source 4 is a cylinder, the latch 5 is connected to the output end of the mold locking drive source 4, the mold locking drive source 4 drives the latch 5 to move back and forth, the pin hole 6 is arranged on the rotation drive source 1, when the rotation drive source 1 drives the coating head 3 to rotate to a certain position, the mold locking drive source 4 drives the latch 5 to be inserted into the pin hole 6 at the corresponding position, and the position of the mold locking drive source 4 is fixed, thereby realizing the position of the coating head 3.

[0037] Specifically, a plurality of pin holes 6 are provided on the rotary driving source 1 , and the number of the pin holes 6 is set correspondingly according to the number of workstations of the coating head 3 .

[0038] In this embodiment, the rotational drive source 1 includes a servo motor and a reducer connected to the servo motor, wherein the reducer is composed of a worm gear and a worm, and the worm gear and the worm gear are engaged and locked to limit the rotational position of the coating head 3, thereby ensuring that the rotational drive source 1 can accurately drive the coating head 3 to rotate to the corresponding workstation every time and can be fixed at the corresponding position.

[0039] Example 2

[0040] Reference Figure 4 As shown, on the basis of the above-mentioned embodiment 1, the utility model further discloses a coating device, including the above-mentioned rotatable coating head 3, and also including: a transfer mechanism 7, the transfer mechanism 7 is connected to the rotatable coating head 3, and drives the rotatable coating head 3 to move in the vertical direction and the horizontal direction. The coating work of the coating head 3 can be realized by first driving the coating head 3 to contact the coating platform through the transfer mechanism 7, and then driving the coating head 3 to make reciprocating motion on the X-axis or Y-axis on the horizontal plane.

[0041] Specifically, in this embodiment, the transfer mechanism 7 is arranged on the gantry 8, and there is an installation space for avoiding the rotating drive source 1 below the gantry 8. The hollow gantry 8 is arranged to support the transfer mechanism 7. On the one hand, it does not affect the transfer mechanism 7 to drive the coating head 3 to move up and down, and on the other hand, it can also avoid the rotating drive source 1 of the rotatable coating head 3.

[0042] Obviously, the above embodiments are only examples for clear explanation and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the invention of the utility model.
