Description

Technical Field

[0001] The utility model relates to the technical field of automated production equipment, in particular to a distillation mechanism for a circuit board rinsing section. Background Art

[0002] During the production and processing of circuit boards, it is necessary to clean the circuit boards with cleaning solutions to remove residual flux on the circuit boards and prevent excess flux from affecting the subsequent production and processing of the circuit boards. Generally, after the circuit boards are cleaned of flux, they also need to be rinsed to prevent residual cleaning solution from remaining on the circuit boards. During the rinsing process, the rinsed solution is recovered and distilled to purify the rinsing solution in the mixed solution. In the distillation tank, in order to monitor the liquid level in the distillation tank, a liquid level sensor is generally installed in the distillation tank or a liquid level mirror is installed on the distillation tank. However, since the solution is heated to boiling in the distillation tank, this causes the liquid level to fluctuate all the time, making it impossible to measure the accurate liquid level.

[0003] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a distillation mechanism for a circuit board rinsing section.

[0006] Furthermore, the communicating tube is made of heat-resistant transparent material.

[0007] Furthermore, an observation mirror is provided on the communicating tube.

[0008] Furthermore, an observation window is provided on the distillation box.

[0009] Furthermore, a liquid inlet is provided on the top of the distillation box.

[0010] Furthermore, a mesh plate is provided near the top of the distillation box, and a plurality of filter mesh holes are regularly and densely distributed on the mesh plate.

[0011] Furthermore, an opening is provided at the top of the distillation box, a sealing upper cover is provided at the opening, a steam outlet is provided at the top of the sealing upper cover, the sealing upper cover is an arc surface or a conical surface, and the steam outlet is provided at the highest point of the arc surface or the conical surface.

[0012] Furthermore, a temperature sensor is provided on the distillation box, and a probe of the temperature sensor extends into the interior of the distillation box.

[0013] Furthermore, a slag discharge port is provided at the bottom of the distillation box.

[0014] By adopting the above scheme, the utility model arranges the communicating tube outside the distillation box and connects it with the top and bottom of the distillation box, thereby providing real-time feedback on the liquid level of the solution in the distillation box according to the communicating tube principle, and monitoring the liquid level inside the communicating tube through the liquid level sensor, thereby improving the detection accuracy of the liquid level and avoiding the situation where the fluctuation of the liquid level caused by the boiling of the liquid in the distillation box affects the detection of the liquid level.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] See also Figure 1 、 Figure 2 The utility model provides a distillation mechanism for the rinsing section of a circuit board, comprising: a distillation box 1, a plurality of heating tubes 2 arranged at the bottom of the distillation box 1, a communication tube 3 arranged on the outside of the distillation box 1, and a liquid level sensor 4 arranged on the communication tube 3, wherein the upper and lower ends of the communication tube 3 are respectively connected to the distillation box 1, and the probe of the liquid level sensor 4 extends into the communication tube 3.

[0020] During operation, the rinsed mixed solution is injected into distillation tank 1. Heating tube 2 heats the mixed solution, causing the rinsing solution in the mixed solution to boil and evaporate. After the mixed solution is injected into distillation tank 1, some of the solution enters manifold 3. Based on the manifold principle, the liquid level in manifold 3 is the same as the liquid level in distillation tank 1. As heating tube 2 heats the solution to boiling, the liquid level in distillation tank 1 fluctuates significantly due to the boiling. While the temperature of the liquid in manifold 3 rises as the solution in distillation tank 1 heats, the liquid in manifold 3 is not directly heated, and bubbles generated during heating by heating tube 2 do not enter manifold 3. Therefore, the liquid level in manifold 3 is relatively stable. Liquid level sensor 4 detects the liquid level in manifold 3, enabling more accurate detection and meeting liquid level monitoring requirements.

[0021] In some embodiments, the communicating tube 3 is made of heat-resistant transparent material, and a corresponding scale is drawn on the communicating tube 3 to facilitate operators to directly observe and judge the liquid level status in the distillation box 1 through the communicating tube 3.

[0022] In some embodiments, an observation mirror is provided on the communicating tube 3 , and a corresponding scale is provided on the observation mirror, so that the operator can directly observe and judge the liquid level in the distillation box 1 through the observation mirror.

[0023] In some embodiments, the distillation box 1 is provided with an observation window 11. When performing distillation or maintenance on the distillation box 1, the internal conditions of the distillation box 1 can be directly observed through the observation window 11, making it easier for operators or maintenance personnel to judge the conditions inside the distillation box 1.

[0024] The top of the distillation box 1 is provided with a liquid inlet 12, which is convenient for feeding the collected rinsed solution into the distillation box 1 for heating and distillation, so as to purify and recover the rinse liquid in the solution, meet the demand for reuse of the liquid medicine, and improve the utilization rate of the liquid medicine.

[0025] In some embodiments, a mesh plate 13 is positioned near the top of the distillation chamber 1. The mesh plate 13 is regularly and densely distributed with filter holes. During the rinsing process, impurities on the circuit boards may be rinsed out. Therefore, when the rinsed solution is injected into the distillation chamber 1, the solution first comes into contact with the mesh plate 13. The solution then passes through the filter holes on the mesh plate 13 and enters the distillation chamber 1 for heating and distillation. Impurities in the solution are intercepted by the filter holes of the mesh plate 13, thereby filtering out the impurities and ensuring the cleanliness of the solution.

[0026] The distillation chamber 1 has an opening at the top, covered by a sealing upper cover 5. A steam outlet 51 is located at the top of the sealing upper cover 5. The sealing upper cover 5 has an arcuate or conical surface, with the steam outlet 51 located at the highest point of the arcuate or conical surface. Since steam tends to move upward, the sealing upper cover 5 is designed as an arcuate or conical surface so that the heated steam can be collected there and discharged through the steam outlet 51 at the highest point of the arcuate or conical surface, facilitating condensation and recycling of the steam at the back end. Furthermore, the sealing upper cover 5 and the top of the distillation chamber 1 are designed as separate, independent structures, facilitating the processing and shaping of the distillation chamber 1 and avoiding the difficulty of machining the arcuate or conical surface at the top. Furthermore, after prolonged use, filter residue may remain on the mesh plate 13. Removing the sealing upper cover 5 facilitates cleaning of the filter residue on the mesh plate 13.

[0027] In some embodiments, the distillation box 1 is provided with a temperature sensor 6, and a probe of the temperature sensor 6 extends into the interior of the distillation box 1. The temperature sensor 6 detects the temperature of the liquid in the distillation box 11 to monitor the heating status of the solution in the distillation box 1.

[0028] See also Figure 3 The bottom of the distillation box 1 is provided with a slag discharge port 14, which is convenient for discharging the waste liquid, impurities, etc. remaining in the distillation box 1 through the slag discharge port 14 during cleaning or maintenance work.

[0029] To sum up, the utility model arranges the communicating tube outside the distillation box and connects it with the top and bottom of the distillation box, so as to provide real-time feedback of the liquid level of the solution in the distillation box according to the communicating tube principle, and monitors the liquid level inside the communicating tube through the liquid level sensor, thereby improving the detection accuracy of the liquid level and avoiding the situation where the fluctuation of the liquid level caused by the boiling of the liquid in the distillation box affects the detection of the liquid level.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
