[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0019] See Figure 1-4This embodiment is a dynamic spray etching device, including: a spray box 01, in which an inlet / outlet section 1, a cleaning section 2, an air-cutting section 3, and an etching section 4 are arranged sequentially from left to right, and adjacent sections are separated by partitions 02; the etching section 4 includes: a rotating support disk 41, multiple horizontal rotating rollers 42 arranged on the rotating support disk 41, and spray components 43 arranged above and below the rotating support disk 41; copper foil is conveyed to the rotating support disk 41 by the rotating rollers 42, and the spray components 43 rotate horizontally synchronously during the up-and-down spray etching of the copper foil;
[0020] In this embodiment, the copper foil is placed horizontally in the inlet / outlet section 1, and passes through the cleaning section 2 and the air cutting section 3 in sequence to reach the etching section 4. During the process of spraying and etching the copper foil, the rotating support disk 41 rotates at the same time, which drives the copper foil to rotate, so as to achieve uniform etching of the copper foil.
[0021] After the copper foil etching is completed, it passes through the air cutting section 3 and the cleaning section 2 in sequence, and is placed at the inlet / outlet section 1. The air cutting section 3 can prevent the water vapor generated by the cleaning section 2 from mixing with the chemical solution at the etching section 4; this layout can also reduce the overall length of the spray box 01.
[0022] In some possible embodiments, in order to illustrate how the rotating bearing disk 41 rotates, this embodiment uses a support part 411 and a drive gear 412 meshing with the rotating bearing disk 41 on one side of the rotating bearing disk 41. The rotating bearing disk 41 is supported on the support part 411 and rotates under the transmission of the drive gear 412.
[0023] In this embodiment, the outer periphery of the rotating bearing disk 41 may be provided with teeth, which mesh with the drive gear 412. The drive gear 412 is controlled by a motor to rotate, driving the rotating bearing disk 41 to rotate. In addition, the support part 411 is used to support the rotating bearing disk 41, so that the rotating bearing disk 41 remains horizontal during rotation.
[0024] In some possible embodiments, to illustrate the rotation of the rotating roller 5 on the rotating support disk 41, this embodiment uses two opposing first supports 51 on the rotating support disk 41. Each first support 51 has a first U-shaped groove 52, and the rotating roller 5 is supported within the corresponding first U-shaped groove 52. A first gear 61 is provided at the support end of the rotating roller 5. A rotating shaft 71 is provided on the outer side of one of the first supports 51, and a second gear 62 meshes with the first gear 61 on the rotating shaft 71. An input shaft 72 is vertically disposed at the bottom of the rotating support disk 41, and its top is connected to an output shaft 73 via a gear pair. The output shaft 73 is horizontally disposed at the bottom of the rotating support disk 41, and a third gear 63 is provided at the end of the output shaft 73, which meshes with one of the second gears 62.
[0025] In this embodiment, the input shaft 72 is controlled to rotate by a motor, and the power is transmitted to the output shaft 73 through the engagement of a gear pair. The output shaft 73 and the rotating shaft 71 are connected by the meshing of the second gear 62 and the third gear 63 to achieve power transmission. Due to the meshing of the second gear 62 and the first gear 61, the rotational power can be transmitted to the rotating roller 5, so as to realize the synchronous rotation of multiple rotating rollers 5, thereby realizing the copper foil moving into or out of the etching section 4.
[0026] In some possible embodiments, to illustrate the specific structure of the spray assembly 43, this embodiment uses the spray assembly 43 as follows: a second support 81 disposed above or below the rotating support plate 41, the second support 81 having a second U-shaped groove 82, the end of the spray pipe 83 being placed in the second U-shaped groove 82 of the second support 81; a plurality of spray rods 83 located above or below are all connected to a first connecting rod 84, the ends of the plurality of first connecting rods 84 are hinged to the same second connecting rod 85, the output shaft of the motor 86 is connected to an eccentric member, the eccentric member being hinged to the end of the corresponding second connecting rod 85 through two third connecting rods 87;
[0027] In this embodiment, the spray pipe 83 is rotatably mounted in the second U-shaped groove 82 of the second bracket 81. The upper spray pipe 83 sprays downwards, and the lower spray pipe 83 sprays upwards. The motor 86 rotates and transmits the rotation to the first link 84 via the third link 87 and the second link 85, thereby realizing the reciprocating rotation of the spray pipe 82. That is, during the spraying process, the spray angle of the spray pipe 82 will be adjusted within a certain range to achieve the purpose of uniform spraying.
[0028] In some possible embodiments, in order to avoid the water vapor generated in the cleaning section during the cleaning process from mixing with the chemical solution in the etching section and affecting the cleaning or etching of the copper foil, this embodiment adopts the air cutting section 3, which includes a plurality of air cutting nozzles 31 arranged vertically, wherein the air cutting nozzles 31 near the cleaning section 2 face the cleaning section 2, and the air cutting nozzles 31 near the etching section 4 face the etching section 4.
[0029] In this embodiment, the upper and lower air-cutting nozzles 31 on the left are set at an angle to the left, and the upper and lower air-cutting nozzles 31 on the right are set at an angle to the right. This can prevent the water vapor generated in the cleaning section 2 during the cleaning process from mixing with the medicine solution in the etching section 4.
[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
