Energy saving device and liquid level stabilization system

Abstract

The present invention discloses an energy-saving device, including: an even number of pushing components and an even number of blocking components. The present invention discloses a liquid level stabilization system. During electroplating, the circuit board slowly enters the pushing member and gradually approaches the blocking member under the push of the pushing member. After the sensing member senses the circuit board, the control system program sends a signal to make the blocking drive member work, and the blocking drive member drives the two blocking members to move in opposite directions and is in an open state. The circuit board continues to move forward and is produced normally; when the sensing member does not sense the circuit board, the control system program sends a signal to make the blocking drive member drive the two blocking members to move in opposite directions and is in a closed state, thereby cutting off the connection between the plating liquid and the outside. In the state where no circuit board enters, the plating liquid cannot flow out, thereby reducing the outflow of the plating liquid, and indirectly reducing the replenishment of the plating liquid. Then, part of the pump body can be stopped, and finally the energy-saving effect is achieved without causing waste of resources.

Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to an energy-saving device and a liquid level stabilization system. Background Art

[0002] With the advancement of science and technology, more and more electronic products are gradually appearing in front of us, and they involve all walks of life. As we all know, the normal operation of electronic products is inseparable from the cooperation between various components, and the connection between components is mainly realized by circuit boards. The inner layer of the circuit board pre-connects various parts, and various components are assembled on the circuit board to achieve connection.

[0003] Circuit boards are processed by multiple processes, including the electroplating process. In order to improve efficiency, circuit boards are electroplated in batches. The specific process is: first prepare a carrier containing electroplating liquid, and then rely on the conveying device to sequentially convey multiple circuit boards into the carrier so that the circuit boards are in contact with the electroplating liquid for electroplating. In order to ensure the electroplating effect (i.e., the circuit board surface is electroplated evenly), one of the links is to ensure the stability of the electroplating liquid level as much as possible. In the actual processing process, due to the overflow of the electroplating liquid in the carrier, a pump body is needed to replenish the electroplating liquid so that the inflow and outflow of the electroplating liquid are equal or close, and finally the liquid level is stable. The disadvantage of the current electroplating process is that the pump body needs to work continuously to continuously replenish the electroplating liquid into the carrier, even if there is no circuit board entering the carrier. In actual situations, the volume of the entire carrier is often large, and multiple pump bodies are required to work to achieve the effect of stabilizing the liquid level. Continuous work when there is no circuit board entering will cause a huge waste of resources and greatly increase the production cost of the enterprise. Summary of the invention

[0032] Embodiment 1

[0033] like Figure 1 As shown, Figure 1It is a schematic diagram of the three-dimensional structure of the energy-saving device. The energy-saving device includes an even number of pushing components 1 and an even number of blocking components 2. The even number of pushing components 1 are arranged opposite to each other in pairs, and the even number of blocking components 2 are also arranged opposite to each other in pairs. Further explanation: when there are only two pushing components 1, the two pushing components 1 are arranged opposite to each other, and a gap is left between them to facilitate the passage of the circuit board 4; when the number of pushing components 1 is four, the four pushing components 1 are divided into two groups, and the two pushing components 1 in each group are arranged opposite to each other, and the two groups of pushing components 1 are arranged side by side along the transportation path of the circuit board 4. Similarly, the specific distribution of the even number of blocking components 2 is the same as the distribution of the even number of pushing components 1, which will not be further elaborated here. For details, please refer to the above. It should be noted that this embodiment will be described in detail by taking two pushing components 1 and two blocking components 2 as an example.

[0034] Please refer to Figure 2 and Figure 3 As shown, Figure 2 It is a schematic diagram of the three-dimensional structure of the pushing component 1; Figure 3 It is another three-dimensional structural schematic diagram of the pushing component 1. The pushing component 1 includes a pushing support member 11, a pushing member 12 and a sensing member 13. The pushing member 12 is rotatably arranged on the pushing support member 11, and the sensing member 13 is arranged on the pushing support member 11. In specific applications, the pushing support member 11 is respectively connected to the two ends of the pushing member 12 to enhance the support for the pushing member 12 and increase the stability of the pushing member 12 when working. In this embodiment, the shape of the pushing member 12 is cylindrical, wherein, in order to avoid corrosion of the pushing member 12 by the electroplating liquid, the pushing member 12 is a roller wound by a polytetrafluoroethylene film. There is a spacing between the two pushing members 12 on the two pushing components 1, and the circuit board 4 can pass through the spacing. When the circuit board 4 is transported, the two pushing members 12 are synchronously driven to rotate relative to the pushing support member 11. Along the conveying path of the circuit board 4, the two sensing members 13 on the two pushing components 1 are located at the front end, and the two sensing members 13 shoot against each other to form a sensing area, that is, the circuit board 4 first passes through the sensing member 13, and then passes through the pushing member 12. When the circuit board 4 passes, the shooting between the two sensing members 13 is blocked, and the sensing member 13 will send a signal at this time. Further explanation, the pushing component 1 also includes an even number of flow reducing members 14, and the flow reducing members 14 are located between the pushing member 12 and the blocking component 2. There is also a spacing between the flow reducing members 14 on the two pushing components 1. The spacing between the two flow reducing members 14 is smaller than the spacing between the two pushing members 12, and the flow reducing members 14 are made of soft materials. When the circuit board 4 contacts the flow reducing member 14, the flow reducing member 14 will deform accordingly, and return to its original state after the circuit board 4 passes. By setting the flow reducing member 14, the loss of the electroplating solution can be reduced.

[0035] Please refer to Figure 4-Figure 7 As shown, Figure 4 is a schematic diagram of the three-dimensional structure of the blocking component 2; Figure 5 is a cross-sectional view of the blocking assembly 2; Figure 6 is another cross-sectional view of the blocking assembly 2; Figure 7 : is a schematic diagram of the three-dimensional structure of the sealing member 25. The blocking assembly 2 includes a blocking support member 21, a blocking movable member 22, a blocking member 23 and a blocking driving member 24. The blocking support member 21 is arranged adjacent to the pushing support member 11. The blocking movable member 22 is slidably arranged on the blocking support member 21. The blocking member 23 is rotatably arranged on the blocking movable member 22. The output end of the blocking driving member 24 is connected to the blocking movable member 22. The blocking support member 21 is provided with a first slide rail 211 and a second slide rail 212. The blocking movable member 22 is slidably connected to the first slide rail 211 and the second slide rail 212 respectively. The blocking movable member 22 includes a first slider 221, a synchronization block 222 and a second slider 223. The first slider 221 is slidably connected to the first slide rail 211, and the second slider 223 is slidably connected to the second slide rail 212. The two ends of the synchronization block 222 are respectively connected to the first slider 221 and the second slider 223. The two ends of the blocking member 23 are rotatably connected to the first slider 221 and the second slider 223. The output end of the blocking driving member 24 is connected to the second slider 223. Through the setting of the synchronization block 222, the synchronization of the movement of the first slider 221 and the second slider 223 is improved. The blocking driving member 24 includes a driving motor 241, a driving screw 242 and a movable seat 243. The driving screw 242 is connected to the output end of the driving motor 241, and the movable seat 243 is arranged on the driving screw 242, and the movable seat 243 is connected to the second slider 223. In this embodiment, the driving screws 242 on the two blocking components 2 share one, that is, the two movable seats 243 are jointly arranged on the same driving screw 242.

[0036] To further illustrate, the blocking assembly 2 further comprises a sealing member 25, which is located between the blocking member 23 and the blocking support member 21. The sealing member 25 is provided with a convex strip 251, which abuts against the outer wall surface of the blocking member 23 to achieve sealing.

[0037] Specifically, the blocking member 23 and the pushing member 12 have the same shape and are made of the same material.

[0038] When the circuit board 4 is being loaded, the induction member 13 senses the circuit board 4 and sends a signal. The signal drives the driving motor 241 to work, and the driving motor 241 drives the driving screw 242 to rotate. The driving screw 242 drives the two movable seats 243 to move in opposite directions. At the same time, the two movable seats 243 drive the two second sliders 223 to move in opposite directions relative to the blocking support member 21, and finally the two blocking members 23 move in opposite directions, leaving a gap between the two for the circuit board 4 to pass through. At this time, the convex strip 251 on the sealing member 25 does not contact the outer wall surface of the blocking member 23. When the induction member 13 does not sense the circuit board 4 for a period of time, it will send a signal to let the driving motor 241 work in the reverse direction, and drive the two movable seats 243 to move in opposite directions through the driving screw 242. At the same time, the convex strip 251 contacts the outer wall surface of the blocking member 23 to prevent the electroplating solution from flowing out of the gap between the blocking member 23 and the blocking support member 21.

[0039] Embodiment 2

[0040] like Figure 8 As shown, Figure 8 The figure is a schematic diagram of the three-dimensional structure of the liquid level stabilization system. The liquid level stabilization system includes two energy-saving devices and a liquid storage component 3. The liquid storage component 3 is provided with an inlet, an outlet (not marked in the figure) and a liquid discharge port. The two energy-saving devices are respectively arranged at the inlet and the outlet. The circuit board 4 passes through the energy-saving device and enters the liquid storage component 3 through the inlet. The liquid storage component 3 is provided with electroplating liquid. The external pump body replenishes the electroplating liquid in the liquid storage component 3. The overflowed electroplating liquid mainly flows out through the liquid discharge port. The energy-saving device in this embodiment is the same as that in the first embodiment, so it will not be described in detail. For details, please refer to the above content.

[0041] During operation, when the push component 1 senses the circuit board 4, it drives the blocking component 2 to open, so that the circuit board 4 can pass through and enter the liquid storage component 3. When the push component 1 does not sense the circuit board 4 for a long time, it drives the blocking component 2 to close, preventing the electroplating liquid in the liquid storage component 3 from continuing to flow out, thereby reducing the replenishment of the electroplating liquid, and part of the pump body can be closed, thereby achieving an energy-saving effect.

[0042] For example, in actual use, the overall volume of the liquid storage component 3 is relatively large. In order to achieve a stable liquid level in the liquid storage component 3, multiple pumps are required to work to replenish the plating liquid. In this embodiment, due to the setting of the blocking component 2, which can prevent the outflow of the plating liquid when it is closed, part of the pump work can be reduced. For example, a pump can save one kilowatt-hour of electricity per hour, and ten kilowatt-hours of electricity can be saved if it works for ten hours a day. And so on. The energy-saving effect brought about by long-term accumulation is outstanding.

[0043] To sum up, through the coordinated use of the pushing component and the blocking component, during electroplating, the circuit board slowly enters the pushing member and gradually approaches the blocking member under the push of the pushing member. At the same time, after the sensing member senses the circuit board, the control system program sends a signal to make the blocking drive member work, and the blocking drive member drives the two blocking members to move oppositely and are in an open state, and the circuit board continues to move forward and production is carried out normally; when the sensing member does not sense the circuit board, the control system program sends a signal to make the blocking drive member drive the two blocking members to move toward each other and are in a closed state, thereby cutting off the connection between the plating solution and the outside. In the state where no circuit board enters, the plating solution cannot flow out, thereby reducing the outflow of the plating solution, and indirectly reducing the replenishment of the plating solution. Then, part of the pump body can be stopped, ultimately achieving the effect of energy saving without causing waste of resources.

[0044] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
