[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention.

[0021] The "left", "right", "front", "rear", "upper", and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0022] Embodiment 1: In some embodiments, please refer to the Figures 1 - 3 continuous glue filling device for the production of a micro-inverter, including a base 1, a material transfer vibration mechanism 2, and a glue dropping mechanism 3; A glue filling rack 11 is fixedly installed on the base 1, and a material transfer vibration mechanism 2 is installed on the base 1; a glue dropping mechanism 3 is installed on the base 1 and the glue filling rack 11; As Figure 2 shown, the material transfer vibration mechanism 2 includes a moving module 21 and a vibration support module 22. The moving module 21 is installed on the base 1, and two groups of vibration support modules 22 for supporting the micro-inverter 4 are installed at the moving end of the moving module 21; As Figure 2 and Figure 3As shown, the glue dropping mechanism 3 includes a glue dropping module 31, an auxiliary vibration module 32, an anti-dripping module 33 and a vibration structure 34. The glue dropping module 31 is installed on the glue filling frame 11. The auxiliary vibration module 32 is installed on the glue dropping module 31. The anti-dripping module 33 is installed on the glue dropping module 31. The vibration structure 34 is installed on the base 1.

[0023] In this embodiment, when the continuous glue filling equipment for the production of the micro-inverter works normally, the micro-inverter 4 is placed on the outer vibration support module 22. The micro-inverter 4 is conformally supported by the vibration support module 22. The moving module 21 drives the vibration support module 22 to move to the lower side of the glue dropping module 31. The glue dropping module 31 is started to drop the glue on the micro-inverter 4 to realize the glue filling of the micro-inverter 4. At the same time, the vibration support module 22 on the other side moves to the outside, and the micro-inverter 4 that has been filled with glue is taken off on the other side and a new micro-inverter 4 is placed on the vibration support module 22. Through the setting of the two groups of vibration support modules 22, when the micro-inverter 4 on one group of vibration support modules 22 is being filled with glue, loading and unloading can be carried out on the other side, improving the overall efficiency. During the glue filling process, the vibration structure 34 strikes the vibration support module 22, and the micro-inverter 4 is driven to vibrate by the vibration support module 22. When the glue filling is about to be completed, the vibration structure 34 can be stopped from striking the vibration support module 22 to avoid the glue flowing out. At the same time, the auxiliary vibration module 32 vibrates some areas inside the micro-inverter 4 to accelerate the flow of the glue in the micro-inverter 4 and avoid the situation that the glue does not flow smoothly between the electrical components in the micro-inverter 4, resulting in the need for subsequent glue replenishment. After the glue filling is completed, the glue dropping module 31 is closed, and at the same time, the anti-dripping module 33 is started to prevent the glue in the glue dropping module 31 from dripping.

[0024] Embodiment 2: In some embodiments, as a preferred embodiment of the present invention, as Figure 4 shown, the moving module 21 includes a moving guide rail 211, a moving cylinder 212 and a moving mounting frame 213.

[0025] In this embodiment, when the moving module 21 and the vibration support module 22 are working properly, the moving cylinder 212 drives the moving mounting frame 213 to move. The moving mounting frame 213 moves horizontally under the limiting action of the moving guide rail 211, thereby driving the two limit disks 221 on the moving mounting frame 213 to move horizontally, so that the two limit disks 221 alternately move to the lower side of the dispensing module 31. When the micro-inverter 4 on one limit support platform 222 is being potted, the potted micro-inverter 4 on the other limit support platform 222 can be removed on the other side. The limit support platform 222 is supported by the vibration springs 226 on the limit disk 221. During the potting process, the vibration structure 34 knocks on the extension plate 227, and the extension plate 227 drives the limit support platform 222 to vibrate, thereby accelerating the flow of the glue liquid of the micro-inverter 4. The micro-inverter 4 is conformally positioned and supported through the receiving groove 223, the first limit groove 224, and the second limit groove 225 on the limit support platform 222, so that the micro-inverter 4 is in a standard position. And when potting different micro-inverters 4, the corresponding limit support platforms 222 can be replaced to improve the applicable range of the device.
