Description

Technical Field

[0001] The invention relates to the field of coding, in particular to an automatic coding device for the bottom of a copper foil roll and a use method thereof. Background Art

[0002] Copper foil coding is to mark the copper foil. During the coding process, the coating surface needs to be kept square. In order to keep the square coating surface, a special nozzle structure needs to be designed to keep the rectangular state. Multiple nozzles need to be designed, and the distribution of the nozzles also needs to be adjusted according to the length, width and height of the coating surface. In addition, the copper foil is continuously transported and operated during the whole process. Therefore, technicians in this field have the following difficulties: How to quickly adjust the length and width of the inkjet area? How to keep the ink dry when designing multiple printheads, to avoid the ink being smeared everywhere due to the copper foil rolling up when the ink is not completely dry; How to keep the edges of the inkjet area neat and avoid unnecessary burrs.

[0003] To this end, we propose a copper foil roll bottom automatic coding device and its use method to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic inkjet coding device for the bottom of a copper foil roll and a method of using the same to solve the problems raised in the above-mentioned background technology. The technical solution of the present invention provides a solution that is significantly different from the prior art in order to solve the technical problem that the prior art solution is too single.

[0005] To achieve the above object, the present invention provides the following technical solutions: A device for automatically spraying codes on the bottom of a copper foil roll and a method for using the device, comprising a driving motor, a storage tank being installed at the bottom of the driving motor, a storage tank being connected to the bottom of the storage tank, a coating chassis being installed on the lower end surface of the storage tank, slide rails being arranged on both sides of the driving motor, a pneumatic telescopic rod being connected to the rear end of the driving motor, and a pneumatic telescopic rod being connected to the outer side of the slide rail via the top of a connecting plate.

[0006] In a further embodiment, the coating chassis has a Reuleaux triangle structure on the side facing the copper foil.

[0007] In a further embodiment, a nozzle is installed at the center of the bottom of the coating chassis, and an ink channel is opened at the bottom of the coating chassis.

[0008] In a further embodiment, the ink channel comprises an oleophobic layer and an oleophilic layer, the oleophobic layer is located on the convex surface, and the oleophilic layer is located on the concave surface.

[0009] In a further embodiment, a rotating disk is slidably connected to the top of the storage tank through an opening, a hose is provided on one side of the rotating disk, a connecting rod is connected inside the storage tank, and the connecting rod is connected to an output end of a driving motor.

[0010] In a further embodiment, the connecting rod is connected to the driving motor via an eccentric shaft.

[0011] In a further embodiment, the ink channel is distributed in a circular shape along the nozzle, and the ink channel extends to the edge of the coating base.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts a single nozzle method to apply a square structure to the coating surface. Compared with the traditional spraying method, to spray the square structure effect, not only multiple nozzles are required, but also repeated debugging and confirmation are required. In particular, the edges of the square structure coating surface may have many burrs. The present application adopts a rotating coating method to quickly spread the ink, so that the burrs on the edges are less and the coating structure is more complete. At the same time, the length and width of the square structure can be guaranteed by the coating residence time and the displacement distance of the electric telescopic rod respectively. The length and width adjustment is simpler and faster, and there is no need to increase or decrease the nozzle and the position of the nozzle like the traditional method.

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-5 In an embodiment of the present invention, an automatic inkjet coding device for the bottom of a copper foil roll and a method for using the same include a driving motor 1, a storage tank 2 is installed at the bottom of the driving motor 1, a storage tank 2 is connected to the bottom of the storage tank 2, a coating chassis 3 is installed on the lower end surface of the storage tank 2, slide rails 4 are arranged on both sides of the driving motor 1, an electric telescopic rod 5 is connected to the rear end of the driving motor 1, a pneumatic telescopic rod 6 is connected to the outer side of the slide rail 4 through the top of the connecting plate, and the coating chassis 3 is in a Leroy triangle structure toward the copper foil side. As a Leroy triangle, the coating chassis 3 can smear a square-shaped coating surface by eccentric rotation.

[0023] A nozzle 301 is installed at the bottom center of the coating chassis 3, and an ink channel 302 is opened at the bottom of the coating chassis 3. The ink channel 302 is mainly used to transport the ink at the nozzle 301 to the edge, so that the entire bottom surface of the coating chassis 3 is covered with ink.

[0024] The ink channel 302 includes an oleophobic layer 3021 and an oleophilic layer 3022. The oleophobic layer 3021 is located on the convex surface, and the oleophilic layer 3022 is located on the concave surface. The oleophilic layer 3022 is used to absorb excess ink, and the excess ink can flow to the oleophobic layer 3021, so that the ink remains on the surface of the copper foil, and the concave surface is more convenient for storing more ink.

[0025] The ink channel 302 is distributed in a circular shape along the nozzle 301 , and extends to the edge of the coating chassis 3 . The ink channel 302 is derived from the center to the outside, so that the ink can be quickly distributed to various positions of the coating chassis 3 .

[0026] Example 2: Please refer to Figure 1-5 , which is different from Example 1, is that a rotating disk 201 is slidably connected to the top of the storage tank 2 through an opening, a hose 202 is provided on one side of the rotating disk 201, a connecting rod 203 is connected to the inside of the storage tank 2, and the connecting rod 203 is connected to the output end of the driving motor 1. The function of the rotating disk 201 is to continuously transport ink to the inside of the storage tank 2. The rotating disk 201 is set to rotate to avoid the hose 202 from rotating together and causing entanglement. The hose 202 can adopt a universal tube, and the output end of the driving motor 1 is connected to the connecting rod 203 to directly drive the storage tank 2 to rotate.

[0027] The connecting rod 203 is connected to the driving motor 1 via an eccentric shaft, and the eccentric shaft is used to drive the coating chassis 3 to rotate to form a square coating surface.

[0028] The working principle of the present invention is: During the lateral movement of the copper foil, the lower part of the device is rapidly lowered by the pneumatic telescopic rod 6, so that the coating chassis 3 and the surface of the copper foil are in contact with each other, and the driving motor 1 is started to drive the storage tank 2 and the coating chassis 3 to rotate. The coating chassis 3 is a Leroy triangle, and a square structure can be coated by eccentric rotation. Meanwhile, during the whole coating process, the ink is sprayed outward from the nozzle 301 and reaches the surface of the copper foil. The ink is evenly spread and coated during the rotation of the coating base 3. Meanwhile, the excess ink is adsorbed by the oleophilic layer 3022 of the ink channel 302 and reserved for the next use. The advantage of this is that during the transportation of the copper foil, since the spraying needs to be completed quickly, it takes time for the ink to be sprayed out and reach the edge of the coating base 3. During this process, the copper foil has moved a certain distance, so it may cause coating leakage. The stored ink can effectively avoid this problem. At the same time, the coating requires a square structure, and the length of the square structure can be determined according to the contact time between the coating chassis 3 and the copper foil, because the copper foil will automatically continue to move forward; The width of the square can be determined by the reciprocating range of the electric telescopic rod 5. The larger the reciprocating range required, the longer the width. It should be noted that the coating chassis 3 and the copper foil surface always maintain a distance of 0.5mm~1mm.

[0029] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
