[0002] The substrate of a thermal printing sheet is an important part of a thermal printer. After a certain current passes through the substrate, the components on the substrate will quickly generate high temperature. When the medium coating on the printing paper encounters high temperature, a chemical reaction will occur and show color. The processing of the substrate generally includes: cleaning, coating, drying, exposure, and etching. Among them, the purpose of etching is to etch away the unprotected non-conductive part of copper on the patterned circuit board made by exposure to form a circuit.

Detailed implementation manners

[0024] The following will describe various exemplary embodiments, features, and aspects of the present application in detail with reference to the drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0025] The special term "exemplary" here means "serving as an example, embodiment, or illustration". Any embodiment described as "exemplary" here does not have to be construed as superior to or better than other embodiments.

[0026] In addition, for a better description of the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can be implemented without some specific details. In some instances, methods, means, and elements well-known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0027] Please refer to Figures 1 to 6 , in the embodiment of the present utility model, a thermal printing sheet circuit etching and cleaning device includes a cleaning tank 1, a pushing component, a flushing structure, and a driving member.

[0028] Specifically, it includes;

[0029] Please refer to Figure 2 , Figure 3 , Figure 4, a cleaning tank 1, in which a pushing component is installed, and further includes a flushing structure, the flushing structure is connected to the pushing component, the pushing component can drive the flushing structure to reciprocate inside the cleaning tank 1, and when moving to the end of the stroke, the flushing structure can change the flushing direction;

[0030] A driving member is installed on the cleaning tank 1 and is connected to the pushing component.

[0031] Of course, a track 5 is arranged inside the cleaning tank 1 for conveying the substrate 4 placed on the track 5. After the substrate 4 is etched, it is conveyed towards the inside of the cleaning tank 1 through the track 5. When it is conveyed directly below the cleaning tank 1, the track 5 stops the conveying work. In this embodiment, the track 5 adopts an intermittent conveying method. When the track 5 conveys the substrate 4 directly below the cleaning tank 1, the conveying work stops, which is convenient for the flushing structure to clean the etched excess copper on the substrate 4. The method of controlling the track 5 belongs to a conventional design, and this embodiment does not make specific limitations on this.

[0032] Specifically, in this embodiment, when using the thermal printing sheet circuit etching and cleaning equipment of the present invention, during use, the track 5 conveys the substrate 4 to the middle position inside the cleaning tank 1, and the driving member is started to perform work. When the driving member works, it drives the pushing component to rotate relative to the cleaning tank 1. Under the limiting action of the mechanical structure, it drives the flushing structure to reciprocate. When the flushing structure moves to the end of the stroke, it is worth mentioning that the so-called end of the stroke in this embodiment refers to the extreme position of the reciprocating motion. Through mechanical transmission, the flushing direction of the flushing structure can be changed, so that during the movement of the flushing structure, the flushing direction of the water flow always faces the substrate 4. Among them, the water flow of the flushing structure is inclined and set to flush towards the substrate 4, so that the broken copper pieces stuck in the corners of the substrate 4 can be flushed away, improving the flushing effect and enabling the circuit diagram on the substrate 4 to be clearly presented.

[0033] It should be noted that a waste water tank is arranged inside the cleaning tank 1. The waste water after flushing the substrate 4 carries the flushed copper pieces and flows into the waste water tank, and then is discharged to the outside through the outlet end arranged at the bottom of the waste water tank.

[0034] After etching, there will be many corners formed on the required pattern of the existing substrate 4, and the water flow flushing from top to bottom cannot effectively remove

[0035] Please refer to Figure 3 , the driving member includes a motor 2, the motor 2 is fixedly installed on the outer wall of the cleaning tank 1, a driving shaft 7 is rotatably installed inside the cleaning tank 1, and one end penetrates through the cleaning tank 1 and is fixedly connected to the output shaft of the motor 2. The driving shaft 7 is rotationally connected to the pushing component through a bevel gear set 8.

[0036] The starting motor 2 operates, and the operation of the motor 2 drives the output shaft to rotate. When the output shaft rotates, it drives the drive shaft 7 to rotate synchronously. When the drive shaft 7 rotates, it drives the pushing component to work through the bevel gear set 8 to achieve the driving requirement.

[0037] Please refer to Figure 4 and Figure 5 , the pushing component includes a transmission shaft 9, the transmission shaft 9 is rotatably installed in the cleaning box 1, the transmission shaft 9 is rotatably connected to the drive shaft 7 through the bevel gear set 8, a rotating member 10 is fixedly installed at one end of the transmission shaft 9, and a convex column 11 is fixedly installed at an eccentric position of the rotating member 10.

[0038] The flushing structure includes a movable plate 12, a through groove is formed on the movable plate 12, the convex column 11 is slidably installed in the through groove, cylinders 13 are symmetrically arranged at both ends of the movable plate 12, guide rods 6 are symmetrically arranged inside the cleaning box 1, a limiting groove is formed on the guide rods 6, and the cylinders 13 are slidably installed in the limiting groove;

[0039] It further includes a support frame 15, the support frame 15 is fixedly installed at one end of the movable plate 12, rotating shafts 20 are rotatably installed at both ends of the support frame 15, and elastic members capable of rotating relative to the support frame 15 are fixedly installed on the rotating shafts 20.

[0040] Specifically, when the drive shaft 7 rotates, it drives the transmission shaft 9 to rotate through the bevel gear set 8. When the transmission shaft 9 rotates, it drives the rotating member 10 to rotate synchronously, and the convex column 11 rotates accordingly. When the convex column 11 rotates, it drives the movable plate 12 to move accordingly. Under the limiting action of the guide rod 6, the movable plate 12 can only make a reciprocating motion inside the cleaning box 1. The moving distance of the movable plate 12 depends on the distance between the convex column 11 and the transmission shaft 9. When the movable plate 12 reciprocates, the cylinder 13 reciprocates on the guide rod 6. At the same time, the movable plate 12 drives the support frame 15 to reciprocate, thereby realizing the flushing work on different positions of the substrate 4 and improving the flushing efficiency.

[0041] Please refer to Figure 6 , the elastic member includes a sleeve plate 17 and a connecting plate 16. The sleeve plate 17 is rotatably installed on the rotating shaft 20. An embedded groove is formed on the support frame 15, the sleeve plate 17 is arranged in the embedded groove, one end of the connecting plate 16 is slidably installed in the sleeve plate 17 and penetrates through the sleeve plate 17, and a spray head 19 is fixedly connected to the end of the connecting plate 16 away from the sleeve plate 17;

[0042] It further includes a spring 18. One end of the spring 18 extends into the sleeve plate 17 and is fixedly connected to the connecting plate 16, and the other end is fixedly connected to the support frame 15.

[0043] A gear 21 is fixedly mounted on the rotating shaft 20, and tooth plates 14 meshing with the gear 21 are symmetrically arranged on the inner walls on both sides of the cleaning box 1. It should be noted that, referring to Figure 5 It can be seen that the symmetrical arrangement here specifically means that a reference plane perpendicular to the horizontal plane is arranged with the center of gravity of the support frame 15 as a reference, and the gear 21 and the toothed plate 14 are arranged on both sides of the support frame 15 respectively with the reference plane as a reference.

[0044] Furthermore, when the movable plate 12 drives the support frame 15 to move to the end of the stroke, the gear 21 and the toothed plate 14 mesh with each other to drive the shaft 20 to rotate. When the shaft 20 rotates, the sleeve plate 17 rotates synchronously. When the sleeve plate 17 rotates, the connecting plate 16 rotates with it. When the connecting plate 16 rotates, the spring 18 is stretched. When the connecting plate 16 rotates to be perpendicular to the support frame 15, the spring 18 changes from a compressed state to a stretched state. At this time, the support frame 15 moves to the end of the stroke. When the support frame 15 starts to move in the opposite direction driven by the movable plate 12, the gear 21 and the toothed plate 14 mesh with each other. The plate 14 continues to mesh and transmit, so that the rotating shaft 20 continues to rotate, driving the connecting plate 16 to rotate. When the connecting plate 16 rotates, it slides relative to the sleeve plate 17, thereby squeezing the spring 18. The spring 18 is squeezed to reserve elastic potential energy. When the gear 21 is disengaged from the tooth plate 14, the connecting plate 16 passes the middle equilibrium position of the spring 18 and is in the end position in a symmetrical orientation. The connecting plate 16 is constrained by the support frame 15 and maintains a deflection angle at this position, so that the nozzle 19 is always tilted toward the substrate 4, so that the broken copper pieces stuck in the corners of the substrate 4 can be washed away, thereby improving the washing effect.

[0045] See also Figure 1 , Figure 6 A water tank 3 is fixedly mounted on the cleaning box 1 , and the water tank 3 is connected to the inner side of the cavity in the connecting plate 16 through a conduit 22 .

[0046] It should be noted that a pump is installed on the water tank 3, and the pump cooperates with the motor 2 so that when the motor 2 is working, it drives the pump to work, so that the water in the water tank 3 is transported toward the inside of the connecting plate 16 to achieve the cleaning of the substrate 4.
