DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the "embodiment" referred to herein refers to a specific feature, structure or characteristic that can be included in at least one implementation of the utility model. The "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0023] Reference Figures 1-4 The embodiment provides an energy-saving mechanism for PCBA surface spraying equipment, including a conveying pipeline 1 and a distribution pipeline 2 connected to each other, a plurality of nozzles 3 being connected to the bottom end of the distribution pipeline 2, a light strip 4 being arranged at the bottom of the distribution pipeline 2, the light strip 4 being a plurality of strips, and the light strip 4 being installed between the nozzles 3, and the light strip 4 being irradiated downward when emitting light, and being able to irradiate the PCBA below the nozzles 3; a valve body 5 being arranged in communication with the conveying pipeline 1, the valve body 5 being rotatably connected to a valve stem 6, the valve body 5 and the valve stem 6 being of a ball valve structure; a rotating shaft 7 being rotatably connected to the valve body 5, the valve stem 6 being transmission-connected to the rotating shaft 7, more specifically, a gear 11 being fixed to the valve stem 6, a gear 2 12 being fixed to the rotating shaft 7, the gear 1 11 being meshed with the gear 2 12; the outer diameter of the gear 2 12 being larger than the outer diameter of the gear 1 11; two paddles 8 being arranged at the rotating shaft 7; a controller 9 for controlling the opening and closing of the light strip 4 being arranged on the conveying pipeline 1, a switch 10 being slidably connected to the controller 9, and the two paddles 8 being respectively located on both sides of the switch 10;

[0024] In this embodiment, the valve stem 6 and the valve body 5 can control the flow of the delivery pipeline 1 and the distribution pipeline 2 as the main valve. In the process of opening the valve stem 6, the valve stem 6 drives the gear 11 to rotate. Since the gear 11 is meshed with the gear 2 12, the gear 2 12 and the rotating shaft 7 are driven to rotate at the same time. Since the paddle 8 rotates synchronously with the rotating shaft 7, when the paddle 8 rotates, the paddle 8 can push the switch 10 to move, thereby controlling the opening and closing of the light strip 4. The outer diameter of the gear 2 12 is larger than the outer diameter of the gear 1 11, that is, the number of teeth of the gear 2 12 is larger than the number of teeth of the gear 1 11. The purpose of such a setting is to reduce the rotation angle of the paddle 8 during the opening and closing of the valve stem 6, thereby reducing the displacement of the paddle 8 and the switch 10. In summary, the opening and closing of the light strip 4 can be controlled when the main valve is opened and closed. Before the spraying operation, the valve stem 6 on the delivery pipeline 1 needs to be opened to open the light strip 4. After the spraying operation, the valve stem 6 on the pipeline is closed to close the light strip 4.

[0025] As a preferred embodiment of the present utility model, the paddle 8 is fixed on the connecting block 13. A groove is formed on the surface of the rotating shaft 7. One end of the connecting block 13 extends into the groove, and a bolt 14 for fixing the connecting block 13 is threadedly connected to the rotating shaft 7;

[0026] In this embodiment, the structure fixed by the bolt 14 can quickly disassemble the paddle 8 and the connecting block 13, facilitating the maintenance or replacement of the switch 10 or other related components.

[0027] As a preferred embodiment of the present utility model, the cross-section of the end of the connecting block 13 extending into the groove and the groove is polygon-shaped;

[0028] In this embodiment, the design of the polygon cross-section can effectively prevent the connecting block 13 from rotating in the groove, failing to achieve the purpose of driving the switch 10 to move.

[0029] As a preferred embodiment of the present utility model, the valve stem 6 is fixed with a handle 15, and the rotation angle of the valve stem 6 is controlled through the handle 15, making the operation more convenient and fast.

[0030] As a preferred embodiment of the present utility model, each nozzle 3 is connected to a manual valve 16. The manual valve 16 can be a ball valve. By setting the manual valve 16, the flow rate passing through the nozzle 3 can be controlled, facilitating the adjustment of the spraying amount.

[0031] As a preferred embodiment of the present utility model, the controller 9 is fixed on the conveying pipeline 1 through a hoop 17. The hoop 17 includes a main body part and a fastener. The main body part is composed of a section of metal strip or plastic strip with certain elasticity, and its shape is annular or semi-annular. The main body part is usually a flat strip structure with a moderate width to provide sufficient contact area and supporting force; Fastener: The two ends of the hoop 17 are connected together through a fastener. The fastener can be a screw, a buckle, a snap or other forms of closing devices; The fastener adopted by this device is a combination of a bolt 14 and a nut. By tightening the nut, the hoop 17 is compressed to make it closely adhere to the pipeline. By setting the hoop 17, the controller 9 can be quickly and firmly installed.

[0032] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made.
