Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board manufacturing technology, specifically to a PCB board cleaning auxiliary tool. Background Technology
[0002] PCB circuit boards are important electronic components. They serve as the support for electronic components and the carrier for the electrical interconnection of these components, playing a crucial role in the manufacturing of electronic equipment.
[0003] In the manufacturing process of electronic products, after the soldering, coating and cleaning processes, PCB boards often need to be cleaned efficiently, uniformly and gently to remove residual flux, solder beads, chemical solutions and particulate contaminants. These impurities can affect the electrical performance and stability of the PCB board, and may even lead to faults such as short circuits and open circuits.
[0004] Currently, the common practice for cleaning PCB boards is to place them directly into a cleaning tank and clean them using a brush or spray gun. However, this method has some problems. During the cleaning process, the PCB board tends to move around in the tank and is difficult to hold in place, making the cleaning operation inconvenient and the cleaning effect less than ideal. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a PCB board cleaning auxiliary tool, which can effectively solve the problems mentioned in the background technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an auxiliary tool for cleaning PCB boards, including a workbench; A grid is fixedly installed in the middle of the workbench. Liquid supply bottles are installed on both sides of the top of the workbench. A crossbeam is fixedly installed between the two sets of liquid supply bottles, and mounting components are installed on the outside of the crossbeams, with the mounting components slidably connected to the crossbeams. Multiple nozzles are installed at the bottom of the mounting components. An infusion tube is connected to the top of each liquid supply bottle, and the other end of the infusion tube is connected to the top side of the mounting component. A fixing assembly is located on the top of the workbench, and two symmetrical sets of fixing components are provided. A recycling assembly is located below the grid. Furthermore, the fixing component includes a connecting rod, which is fixedly installed on the top of the workbench. A mounting block is fixedly installed at one end of the connecting rod, and a first clamping plate is fixedly installed on the top side of one side of the mounting block. A second clamping plate is provided below the first clamping plate, and a slider is fixedly installed on one side of the second clamping plate. A sliding groove is opened on one side of the mounting block, and the slider is embedded in the sliding groove and slidably connected to the slider. A screw is installed at the bottom of the sliding groove through a bearing, and the screw passes through the middle of the slider through a thread. The top of the screw passes through the mounting block and is fixedly installed with a knob, thereby realizing the function of clamping the PCB board.
[0007] Furthermore, the connecting rod is made of shape memory alloy, which is a smart material that can recover a preset shape within a specific temperature range. Its characteristics originate from the reversible phase transformation of the internal austenite and martensite crystal structure, and it has the characteristics of large bending range and high plasticity, which enables the device to adapt to PCB boards of different sizes and clamp and fix them.
[0008] Furthermore, rubber pads are pressed onto the bottom surface of the first clamping plate and the top surface of the second clamping plate. The rubber pads are made of natural rubber, but synthetic rubber is generally used. Synthetic rubber is a rubber material manufactured through chemical synthesis and has properties similar to natural rubber. Synthetic rubber can be formulated according to different needs to obtain specific physical and chemical properties, and has the characteristics of strong sealing, anti-slip, wear resistance and high elasticity. This design utilizes the high elasticity and anti-slip characteristics of rubber, which can prevent the first clamping plate and the second clamping plate from crushing the PCB board, while increasing the friction between the PCB board and the first clamping plate and the second clamping plate to prevent it from slipping.
[0009] Furthermore, the recycling component includes a base located below the center of the grid. Filter screens are fixedly installed on both sides of the top of the base, and liquid collection tanks are installed on both the left and right sides of the base. A drain pipe is connected to one side of the liquid collection tank and passes through one side of the workbench, facilitating the recycling of waste liquid and reducing its impact on the processing environment.
[0010] Furthermore, the filter screen is set at an angle, so that solid residues in the waste liquid can slide down between the two sets of filter screens, which helps to prevent solid residues in the waste liquid from clogging the filter holes.
[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. By fixing a connecting rod to the top of the workbench, and fixing an installation block to one end of the connecting rod, and setting a first clamping plate and a second clamping plate on one side of the installation block, after placing the PCB board above the grid, the first clamping plate and the second clamping plate are clamped by rotating the knob, which can firmly fix PCB boards of different sizes and shapes, prevent the PCB board from shaking during the cleaning process, and ensure the stability of the cleaning operation.
[0012] 2. By setting a base below the grid, and fixing filter screens on both sides of the top of the base, and setting a collection tank below the filter screens, the waste liquid after cleaning will pass through the grid and filter screens and fall into the collection tank. The filter screens can block the residue at the top of the filter screens. This design can recycle and reuse the waste liquid, which is conducive to reducing environmental impact.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0017] The present invention will be further described below with reference to the embodiments.
[0018] Example 1: Reference Figure 1-2 This is the first embodiment of the present utility model, which discloses a PCB board cleaning auxiliary tool, characterized in that it includes a workbench 1; A grid 2 is fixedly installed in the middle of the workbench 1. Liquid supply bottles 3 are installed on both sides of the top of the workbench 1. A crossbeam 4 is fixedly installed between the two sets of liquid supply bottles 3. An installation part 5 is installed on the outside of the crossbeam 4. The installation part 5 is slidably connected to the crossbeam 4. A nozzle 6 is installed at the bottom of the installation part 5. Multiple sets of nozzles 6 are provided. An infusion pipe 7 is connected to the top of the liquid supply bottle 3. The other end of the infusion pipe 7 is connected to the top side of the installation part 5. A fixing assembly is provided on the top of the workbench 1. The fixing assembly has two symmetrical sets. The fixing assembly includes a connecting rod 8, which is fixedly installed on the top of the workbench 1. A mounting block 9 is fixedly installed on one end of the connecting rod 8. A first clamping plate 10 is fixedly installed on the top side of one side of the mounting block 9. A second clamping plate 12 is provided below the first clamping plate 10. A slider 13 is fixedly installed on one side of the second clamping plate 12. A sliding groove 11 is provided on one side of the mounting block 9. The slider 13 is embedded in the sliding groove 11 and is slidably connected to the slider 13. A screw 14 is installed at the bottom of the sliding groove 11 through a bearing. The screw 14 passes through the middle of the slider 13 through a thread. The top of the screw 14 passes through the mounting block 9 and is fixedly installed with a knob 15. Connecting rod 8 is made of shape memory alloy. Rubber pads are pressed onto the bottom surface of the first clamping plate 10 and the top surface of the second clamping plate 12.
[0019] Example 2: Reference Figure 3-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a recycling component is provided below the grid 2. The recycling component includes a base 16, which is located in the middle of the lower part of the grid 2. Filter screens 17 are fixedly installed on both sides of the top of the base 16. Liquid collection tanks 18 are installed on both the left and right sides of the base 16. A drain pipe 19 is connected to one side of the liquid collection tank 18 and the drain pipe 19 passes through one side of the workbench 1. The filter screen 17 is set to an angle.
[0020] The remaining structure is the same as that in Example 1.
[0021] The workflow of this utility model is as follows: First, place the PCB board above the grid 2. Then, adjust the shape of the left and right connecting rods 8 according to the size of the PCB board. Place the two sets of first clamping plates 10 on the two sides of the PCB board. After rotating the knob 15, the knob 15 can drive the screw 14 to rotate. The screw 14 can drive the slider 13 to move upward. The slider 13 drives the second clamping plate 12 to move upward and cooperate with the first clamping plate 10 to clamp the sides of the PCB board. The two sets of first clamping plates 10 and second clamping plates 12 clamp and fix the two sides of the PCB board. Secondly, the liquid extraction device inside the mounting component 5 can draw liquid from the supply bottle 3 through the infusion pipe 7 and spray it out through the nozzle 6, which can then be used in conjunction with the brush to start cleaning the PCB board. At the same time, the mounting component 5 can be moved laterally so that it slides on the crossbeam 4, thereby adjusting the position of the nozzle 6 spraying the cleaning liquid. Finally, the waste liquid after cleaning will fall through the grid 2 and onto the filter screen 17 due to gravity. After being filtered by the filter screen 17, the solid residue in the waste liquid will be blocked above the filter screen 17, and the remaining waste liquid will fall into the collection tank 18 and finally be discharged through the drain pipe 19.
