Description

Technical Field

[0001] This utility model relates to the field of self-regulation technology, specifically to a coupling agent supply self-regulation device. Background Technology

[0002] In the application of copper foil in electronic circuits, after a series of complex surface metal electroplating and cleaning processes, the copper foil surface is treated with a coupling agent. This step aims to establish a strong molecular bridge between the copper foil and the PP board through specific chemical coupling, thereby significantly improving the adhesion strength between the two.

[0003] To improve the utilization rate of coupling agent, the coupling agent after coupling with copper foil is usually recovered and returned to the supply tank. After being mixed with the coupling agent solution in the supply tank, it is then transported to the surface of copper foil to perform coupling treatment on the copper foil.

[0004] However, in practical applications, the introduction of residual cleaning water from the preceding process of coupling agent treatment leads to an increase in the liquid volume within the supply tank during the continuous transport of the coupling agent and the return of the recovered liquid. This results in significant dilution of the coupling agent in the supply tank. Typically, a portion of the coupling agent in the supply tank is manually drained to maintain the tank volume within a suitable range, while freshly prepared coupling agent is added to increase its concentration. However, this method results in significant fluctuations in the coupling agent concentration during draining and replenishing, greatly reducing the stability of the coupling treatment effect.

[0043] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] Example 1:

[0045] refer to Figure 1-5 A self-regulating coupling agent supply device includes a supply tank 1, multiple conveying rollers 2, a spray assembly 3, a recovery box 4, two receiving boxes 5, a storage tank 6, and an adjustment assembly 7. The supply tank 1 is connected to a coupling agent conveying device and can serve as a temporary storage tank for the coupling agent and a device for adjusting the coupling agent concentration. Copper foil is provided between the multiple conveying rollers 2 for transporting the copper foil; this is prior art and will not be described in detail here. The spray assembly 3 is connected to the supply tank 1 and can be connected to a pump to spray the coupling agent in the supply tank 1 onto the surface of the copper foil; this is prior art and will not be described in detail here. The recovery box 4 is located at the bottom of the multiple conveying rollers 2 and is connected to the supply tank 1, and can collect the recovered liquid (from the conveying rollers 2 and the copper foil). The dripping coupling agent solution is transported to the supply tank 1. Two receiving boxes 5 are symmetrically arranged below both ends of the conveying roller 2 and above the recovery box 4. They can intercept the recovery liquid entering the recovery box 4, thereby reducing the amount of recovery liquid transported to the supply tank 1. The storage tank 6 and the two receiving boxes 5 can be connected by a pipe, which can be a flexible hose. This ensures that the liquid can move while the receiving boxes 5 are in motion, and that the liquid between the storage tank 6 and the two receiving boxes 5 can flow normally. The storage tank 6 can store the recovery liquid collected by the receiving boxes 5. The adjusting component 7 can automatically adjust the length of the receiving box 5 located directly below both ends of the conveying roller 2, thereby adjusting the area of ​​the receiving box 5 that intercepts the recovery liquid, and thus adjusting the amount of recovery liquid entering the recovery box 4.

[0046] In some embodiments, the adjustment component 7 includes a first liquid level monitoring element, a drive element 71, and an adjustment element. The first liquid level monitoring element may be a liquid level monitor, which is installed in the liquid supply tank 1 to monitor the liquid level height in the liquid supply tank 1 in real time. The drive element 71 is connected to the first liquid level monitoring element and may be a rotary motor. It performs corresponding actions based on the data fed back by the first liquid level monitoring element. The adjustment element is located between the drive element 71 and the liquid receiving box 5. Based on the liquid level height measured by the liquid level monitor, the drive element 71 is controlled to drive the adjustment element, thereby controlling the area of ​​the liquid receiving box 5 that intercepts the recovered liquid.

[0047] In some embodiments, the adjusting component includes a nut 72 and a screw 73. The nut 72 is fixedly connected to the driving component 71, and one end of the screw 73 is fixedly connected to the liquid receiving box 5, while the other end is screwed into the nut 72. The driving component 71 drives the nut 72 to rotate, thereby causing the screw 73 to rotate accordingly. Since the weight of the liquid receiving box 5 is greater than the transmission force between the screw 73 and the nut 72, the screw 73 and the nut 72 move relative to each other, thereby causing the liquid receiving box 5 to move along the axial direction of the guide roller 2, thus adjusting the area of ​​the liquid receiving box 5 that intercepts and recovers the liquid.

[0048] In some embodiments, the nut 72 includes a nut body 721, a threaded groove 722, and an anti-detachment groove 723. The nut body 721 is fixedly connected to the drive member 71. The threaded groove 722 is located at one end of the nut body 721 near the screw 73 and is threadedly engaged with the screw 73. The anti-detachment groove 723 is located at one end of the nut body 721 away from the screw 73. The screw 73 includes a threaded portion 731 and an anti-detachment portion 732. One end of the threaded portion 731 is threadedly engaged with the threaded groove 722, and the other end is fixedly connected to the liquid receiving box 5. The anti-detachment portion 732 is located at the end of the threaded portion 731 away from the liquid receiving box 5 and can slide in the anti-detachment groove 723. The diameter of the anti-detachment portion 732 can be larger than the diameter of the threaded portion 731 to ensure that the screw 73 will not fall out of the nut 72.

[0049] In some embodiments, the liquid receiving box 5 includes a box body 51, a support frame 52, and rollers 53. The box body 51 is located above the recovery box 4 and connected to the liquid storage tank 6. Two support frames 52 are symmetrically arranged on both sides of the box body 51, and the recovery box 4 is located between the two support frames 52. The rollers 53 are located at the bottom of the support frames 52, which can reduce the friction when the liquid receiving box 5 moves, facilitate the movement of the liquid receiving box 5, and thus improve the adjustment accuracy.

[0050] In some embodiments, a control component 8 is further included. The control component 8 is disposed between the storage tank 6 and the two receiving boxes 5. The control component 8 includes a second liquid level monitoring device, an inlet valve 81, a three-way pipe, a drain valve 82, and a drain pipe 83. The inlet valve 81 is disposed between the storage tank 6 and the two receiving boxes 5 and can control the connection and disconnection between the storage tank 6 and the two receiving boxes 5. The three-way pipe is disposed between the inlet valve 81 and the two receiving boxes 5. One end of the drain valve 82 is connected to the three-way pipe, and the drain pipe 83 is connected to the other end of the drain valve 82. The drain pipe 83 can be connected to a waste liquid treatment device and can control the connection and disconnection between the three-way pipe and the drain pipe 83. Both the inlet valve 81 and the drain valve 82 are connected to the second liquid level monitoring device. The monitoring device is electrically connected. Both the inlet valve 81 and the outlet valve 82 can be solenoid valves. When the second liquid level monitoring device detects that the liquid level in the storage tank 6 has reached the set value, the second liquid level monitoring device sends a signal, the inlet valve 81 closes and the outlet valve 82 opens, the two liquid receiving boxes 5 are disconnected from the storage tank 6 and connected to the outlet pipe 83, so that the recovered liquid collected by the two liquid receiving boxes 5 is discharged from the outlet pipe 83 and does not enter the storage tank 6. When the second liquid level monitoring device detects that the liquid level in the storage tank 6 has not reached the set value, the second liquid level monitoring device sends a signal, the inlet valve 81 opens and the outlet valve 82 closes, the two liquid receiving boxes 5 are connected to the storage tank 6, so that the recovered liquid collected by the two liquid receiving boxes 5 flows into the storage tank 6.

[0051] The specific working principle is as follows:

[0052] The coupling agent enters the supply tank 1 through the conveying device. The supply tank 1 conveys the coupling agent to the spraying assembly 3. The spraying assembly 3 evenly sprays the coupling agent in the supply tank 1 onto the surface of the copper foil. Part of the coupling agent solution dripping from the guide roller 2 and the copper foil drips into the recovery box 4 and is conveyed into the supply tank 1 through the height difference between the recovery box 4 and the supply tank 1. The other part drips into the two receiving boxes 5 and is conveyed into the storage tank 6 through the height difference between the receiving box 5 and the storage tank 6.

[0053] The first liquid level monitoring device monitors the liquid level in the supply tank 1 in real time. When the liquid level is lower than the set value, the drive component 71 rotates, causing the nut 72 to rotate. Through the screw connection between the nut 72 and the screw rod 73, the screw rod 73 causes the two receiving boxes 5 to move away from each other, thereby reducing the length of the receiving box 5 directly below the guide roller 2, reducing the amount of recovered liquid entering the receiving box 5, and thus increasing the amount of recovered liquid entering the recovery box 4, thereby raising the liquid level in the supply tank 1. When the liquid level is higher than the set value, the drive component 71 rotates in the opposite direction, causing the nut 72 to rotate in the opposite direction. Through the screw connection between the nut 72 and the screw rod 73, the screw rod 73 causes the two receiving boxes 5 to move closer to each other, thereby increasing the length of the receiving box 5 directly below the guide roller 2, increasing the amount of recovered liquid entering the receiving box 5, and thus reducing the amount of recovered liquid entering the recovery box 4, thereby lowering the liquid level in the supply tank 1.

[0054] Example 2:

[0055] refer to Figure 6 The difference between this embodiment and Embodiment 1 is that:

[0056] The storage tank 6 is connected to the supply tank 1. The outlet of the storage tank 6 can be higher than the inlet of the supply tank 1. A control valve (not shown in the figure) is provided between the storage tank 6 and the supply tank 1. The control valve can be a solenoid valve. The coupling agent solution can be prepared using the recovered liquid in the storage tank 6. The control valve can be opened as needed to deliver the coupling agent in the storage tank 6 to the supply tank 1, further improving the adjustment flexibility of the self-regulating device.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
