Description

Technical Field

[0001] The utility model relates to the technical field of slicing and potting, in particular to an auxiliary device for improving the yellowing of large slicing potting. Background Art

[0002] In the case of quality determination and quality abnormality analysis of a PCB, it is usually necessary to slice the PCB to directly cut out the part to be observed. Then, in order to be able to store the slice of the PCB for a long time, potting processing is also carried out on the slice of the PCB to fix the slice in a glue block.

[0003] Currently, most of them directly put a large blade into the mold groove, then pour glue into the mold groove, and then wait for the glue to cure. However, the existing potting method has the following deficiencies:

[0004] In the existing method, during the natural curing process after potting a large sample, the glue will have a strong heat generation reaction, and this strong heat generation reaction will cause the glue itself to change color, showing phenomena such as yellowing and redness, resulting in a decrease in transparency, which will further affect the observation effect and is not convenient to use.

[0005] In view of the above problems, the utility model document proposes an auxiliary device for improving the yellowing of large slicing potting. Content of the Utility Model

[0006] The utility model provides an auxiliary device for improving the yellowing of large slicing potting, which solves the deficiencies in the prior art that during the natural curing process after potting a large sample, the glue will have a strong heat generation reaction, and this strong heat generation reaction will cause the glue itself to change color, showing phenomena such as yellowing and redness, resulting in a decrease in transparency, which will further affect the observation effect and is not convenient to use.

[0007] The utility model provides the following technical solutions:

[0008] An auxiliary device for improving the yellowing of large slicing potting, comprising:

[0009] A bottom plate, a support seat is fixedly arranged on the top of the bottom plate, a cooling box is arranged on the top of the support seat, a mold box is arranged inside the cooling box, and a support frame is fixedly arranged on the top of the bottom plate;

[0010] An auxiliary mechanism, which is arranged on the bottom plate and is used to assist the glue poured into the mold box to cure quickly;

[0011] A circulation mechanism, which is arranged on the bottom plate and is used to recycle and reuse the water in the cooling box.

[0012] In a possible design, the auxiliary mechanism includes a drain pipe and a water injection pipe. The drain pipe and the water injection pipe are respectively connected to both sides of the cooling box, and a drain solenoid valve and a water injection solenoid valve are respectively arranged on the outer walls of the drain pipe and the water injection pipe.

[0013] In a possible design, a temperature sensor is fixedly installed on one side of the cooling box, and a controller is arranged on one side of the mold box.

[0014] In a possible design, the circulation mechanism includes a water collecting tank and a cooler. Both the water collecting tank and the cooler are arranged on the top side of the bottom plate. The water collecting tank and the cooler are connected and communicated through a connecting pipe, and the top side of the water collecting tank is connected and communicated with the bottom end of the drain pipe.

[0015] In a possible design, a cold water tank is arranged on the top side of the support frame. The cold water tank and the cooler are connected and communicated through a water inlet pipe, and the bottom side of the cold water tank is connected and communicated with one end of the water injection pipe.

[0016] In a possible design, support rods are symmetrically arranged in pairs at the bottom of the mold box. The tops of the four support rods are fixedly provided with threaded rods, and threaded holes for threaded connection of the threaded rods are symmetrically opened in pairs on the bottom side of the mold box.

[0017] In a possible design, a suction cup for adsorbing the bottom side of the inner wall of the cooling box is fixedly installed at the bottom end of each support rod.

[0018] In this application, during use, first, the threaded rod is threadedly connected to the threaded holes on the bottom side of the mold box, and the four support rods are threadedly installed on the mold box. Since these support rods are detachable, they can be used for fixing large slicing mold boxes of different types and sizes. At the same time, the suction cups at the bottom ends of the support rods can adsorb on the inner wall of the cooling box, providing stable support force to ensure that the mold box will not shake or shift during the cooling process, achieving the effect of convenient disassembly and installation, improving convenience. After the mold box is fixed in place, the large slicing sample to be processed is placed and fixed inside the mold box. At this time, the adjusted glue is directly poured slowly into the mold box for curing operation. When the glue is poured into the mold box, it needs to be quickly cured to reduce the yellowing phenomenon. The water injection solenoid valve is activated through the controller, so that cold water flows into the cooling box through the water injection pipe and surrounds the mold box. The temperature sensor can monitor the water temperature in the cooling box in real time and feedback the data to the controller. The controller automatically adjusts the opening and closing of the water injection solenoid valve and the drain solenoid valve according to the preset temperature threshold and the real-time temperature data to keep the water temperature in the cooling box within the appropriate range. The cooling water can quickly reduce the temperature of the mold box and the glue inside, thereby accelerating the curing process of the glue, which is beneficial to preventing the glue from having a strong heat generation reaction, which may cause the glue itself to change color and show phenomena such as yellowing and reddening, avoiding a decrease in transparency and affecting the observation effect, so that the cured sample is transparent and the morphology of the specimen can be observed intuitively; when grinding the slice, it can be accurately ground to the position to be observed;

[0019] When the water temperature in the cooling box rises, the drain solenoid valve is opened again through the controller, so that the high-temperature water flows out through the drain pipe, providing a continuous low-temperature environment for the cooling box. The drain pipe discharges the high-temperature water into the water collection tank. The water in the water collection tank flows into the cooler through the connecting pipe for cooling treatment. The cooler reduces the water temperature to a suitable temperature for reuse through its internal refrigeration components. The cooled water flows into the cold water tank through the water inlet pipe for storage. When the mold box needs to be cooled again, the cold water re-enters the cooling box through the water injection pipe, forming a closed-loop system of water circulation, facilitating the recycling of the used water, avoiding a large amount of loss and wasting water resources, and improving the use effect.

[0020] In this utility model, for the auxiliary device for improving the yellowing of large slicing resin infusion, through the auxiliary mechanism, the temperature of the mold box and the glue inside can be quickly reduced, thereby accelerating the curing process of the glue, which is beneficial to preventing the glue from having a strong heat generation reaction;

[0021] In this utility model, for the auxiliary device for improving the yellowing of large slicing resin infusion, through the circulation mechanism, a closed-loop system of water circulation can be formed, facilitating the recycling of the used water, avoiding a large amount of loss and wasting water resources, and improving the use effect;

[0022] In the present utility model, it is beneficial to prevent the glue from generating a strong heat reaction, which may cause the glue itself to change color due to this strong heat reaction, showing phenomena such as turning yellow or red, avoiding a decrease in transparency and affecting the observation effect, and facilitating use.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Embodiment 1

[0031] Please refer to Figures 1 - 4 , an auxiliary device, comprising:

[0032] A bottom plate 1, on the top of which a support seat 2 is fixedly arranged, on the top of the support seat 2 a cooling box 3 is arranged, inside the cooling box 3 a mold box 4 is arranged, on the top of the bottom plate 1 a support frame 17 is fixedly arranged. The support seat 2 can stably support the cooling box 3, the support frame 17 can stably support the cold water tank 15, and the mold box 4 can place and fix the large slice sample to be processed inside, facilitating subsequent use;

[0033] Auxiliary mechanism. The auxiliary mechanism is arranged on the bottom plate 1 and is used to assist the glue poured into the mold box 4 to cure quickly. The auxiliary mechanism includes a drain pipe 11 and a water injection pipe 18. The drain pipe 11 and the water injection pipe 18 are respectively connected to both sides of the cooling box 3. Drainage solenoid valves 12 and water injection solenoid valves 19 are respectively arranged on the outer walls of the drain pipe 11 and the water injection pipe 18. A temperature sensor 5 is fixedly installed on one side of the cooling box 3, and a controller 20 is arranged on one side of the mold box 4.

[0034] The water injection solenoid valve 19 is started through the controller 20, so that cold water flows into the cooling box 3 through the water injection pipe 18. The temperature sensor 5 can monitor the water temperature in the cooling box 3 in real time and feed the data back to the controller 20. The controller 20 automatically adjusts the opening and closing of the water injection solenoid valve 19 and the drainage solenoid valve 12 according to the preset temperature threshold and the real-time temperature data to keep the water temperature in the cooling box 3 within a suitable range. The cooling water can quickly reduce the temperature of the mold box 4 and the glue inside it, thereby accelerating the curing process of the glue, which is beneficial to preventing the glue from generating a strong heat reaction, making the cured sample transparent and enabling the morphology of the specimen to be observed intuitively. When slicing and grinding, the position to be observed can be accurately ground.

[0035] Circulation mechanism. The circulation mechanism is arranged on the bottom plate 1 and is used to recycle the water in the cooling box 3. The circulation mechanism includes a water collection tank 10 and a cooler 13. Both the water collection tank 10 and the cooler 13 are arranged on the top side of the bottom plate 1. The water collection tank 10 and the cooler 13 are connected through a connecting pipe 14. The top side of the water collection tank 10 is connected to the bottom end of the drain pipe 11. A cold water tank 15 is arranged on the top side of the support frame 17. The cold water tank 15 and the cooler 13 are connected through a water inlet pipe 16. The bottom side of the cold water tank 15 is connected to one end of the water injection pipe 18.

[0036] When the water temperature in the cooling box 3 rises, the drainage solenoid valve 12 is opened again through the controller 20, so that the high-temperature water flows out through the drain pipe 11. The drain pipe 11 discharges the high-temperature water into the water collection tank 10. The water in the water collection tank 10 flows into the cooler 13 through the connecting pipe 14 for cooling treatment. The cooler 13 reduces the water temperature to a temperature suitable for reuse through its internal refrigeration components. The cooled water flows into the cold water tank 15 through the water inlet pipe 16 for storage. When it is necessary to cool the mold box 4 again, the cold water re-enters the cooling box 3 through the water injection pipe 18, forming a closed-loop system for water circulation, which is convenient for recycling the used water and avoiding a large amount of loss and waste of water resources.
