Description

Technical Field

[0001] The utility model relates to the technical field of curing equipment for metallographic sections, in particular to a curing machine. Background Art

[0002] A metallographic section is a specimen required for metallographic inspection. It is a sample preparation method in which a sample is encapsulated and sealed with a special liquid resin and then ground and polished. The specimen process includes sampling, encapsulation, grinding, polishing, providing morphology photos later, judging the size of cracking and delamination or providing data such as size, etc. It is a common analysis method for observing the cross-sectional microstructure of a sample. It is widely used in the electronics industry, metal / plastic / ceramic product industry, automotive parts and accessories manufacturing industry, communication equipment, scientific research, observation of the structure of electronic components, such as flip chips, aluminum / copper process structures, COMS, POP, etc., observation of PCB structures and vias, observation of PCBA solder joints, observation of LED structures, IMC observation, capacitors, paint thickness, coatings, observation of the structure of metals and parts, etc. The curing machine is an essential equipment for the encapsulation of metallographic sections.

[0003] Due to the characteristics of the curing glue, in practical operations, there are usually problems such as gaps between the glue and the surface of the attached metallographic section and the target holes of the metallographic section not being filled with glue. Moreover, during the curing process, different parts of the metallographic section have uneven heating due to different light intensities, which will all cause bubbles to be generated during the curing process, greatly affecting the quality of the next grinding process.

[0004] The metallographic section is encapsulated and cured with a curing glue. Traditional curing glues are generally prepared from two-component or multi-component glues. Such curing glues emit extremely strong and pungent gases, which are not friendly to the working environment. At the same time, the curing glue is configured with two components or multiple components and is temporarily prepared before encapsulation is required. Therefore, it is inconvenient to operate during the specific operation process. The component ratios are not necessarily unified each time, resulting in unstable curing quality, ineffective control of the curing time, and long waiting time for workers. At the same time, a large amount of curing glue is wasted during the preparation process, and the utilization rate is low.

[0005] In summary, the existing structure obviously has inconveniences and defects in actual use, so it is necessary to be improved. Summary of the Utility Model

[0028] The curing machine of the utility model is provided with a first curing cabin and a second curing cabin; the first curing cabin is used for preliminary curing (preliminary curing is to achieve the basic solidification effect of UV glue (Ultraviolet, ultraviolet curing glue), that is, the UV glue does not have the phenomenon of flowing liquid), and includes a first cabin, a first curing box bracket, a first UV light source and a light absorbing cover; the first UV light source is arranged below the first curing box bracket; the light absorbing cover is arranged above the first curing box bracket; the mold box loaded with metallographic sections and filled with UV glue is placed vertically in the first curing box bracket, that is, the first opening of the mold box is placed upward. Optionally, the curing box is detachably connected to the first curing box bracket, and the shape of the receiving groove on the curing box is configured to match the shape of the first opening of the mold box when it is facing upward, thereby placing the mold box in the receiving groove, the first opening of the mold box can be kept facing upward, and it is not easy to tip over, and the light from below can be irradiated into the mold box through the hollow area provided in the receiving groove. In the first curing chamber, only the first UV light source is provided below the first curing box bracket, while there is no UV light source above the first curing box bracket, and a light absorbing cover is also provided above it to prevent the ultraviolet light irradiated from below from irradiating the UV glue above by reflection, so as to ensure that the UV glue below must be cured before the UV glue above.

[0049] In this embodiment, the curing machine 100 is used to cure the UV glue 5 in the mold box 2 loaded with the metallographic section 1. Refer to Figure 1, according to the process requirements, the metallographic section 1 may include a target hole 3, which refers to a position where the internal structure is analyzed after processes such as grinding and polishing. The mold box 2 is used to load and seal the metallographic section 1. The mold box 2 is a transparent container with a closed bottom and a first opening 4 at the top. The side in contact with the metallographic section 1 is the front of the mold box 2, and the opposite side is the back of the mold box 2. After the metallographic section 1 is loaded into the mold box 2, the UV glue 5 is poured into the accommodating cavity of the mold box 2 from the first opening 4 at the top of the mold box 2 to fill the accommodating cavity, and is cured through the curing chamber of the curing machine 100. The curing machine 100 is provided with a first curing chamber 20 and a second curing chamber 30. The first curing chamber 20 is used for preliminary curing, and the second curing chamber 30 is used for deep curing. Preliminary curing through the first curing chamber 20 in advance can reduce the generation of bubbles during the curing process. Specifically, the first curing chamber 20 includes a first chamber body 21, a first curing box bracket 22, a first UV light source 23, and a light absorption cover 24; the first chamber body 21 can be integrally formed by the internal structure of the frame body 10. Of course, in order to facilitate the installation of the first curing box bracket 22, the first UV light source 23, and the light absorption cover 24, the first chamber body 21 can be configured separately and then installed on the frame body 10. The first chamber body 21 can be used to install the first curing box bracket 22, the first UV light source 23, and the light absorption cover 24; the first UV light source 23 is arranged below the first curing box bracket 22; the light absorption cover 24 is arranged above the first curing box bracket 22; the mold box 2 loaded with the metallographic section 1 and filled with the UV glue 5 is placed vertically in the first curing box bracket 22, that is, the first opening 4 of the mold box 2 faces upward and is placed in the first curing box bracket 22. Only the first UV light source 23 is provided below the first curing box bracket 22 in the first curing chamber 20, and there is no UV light source above the first curing box bracket 22, and a light absorption cover 24 is also provided above it to prevent the ultraviolet light irradiated from below from irradiating the UV glue above through reflection, so as to ensure that the UV glue below must be cured before the UV glue above. Thus, in the first curing chamber 20, the UV glue 5 starts to cure from the bottom of the mold box 2, and the heat generated during the curing process is discharged through the UV glue 5 in the liquid state above, and the generated bubbles can also be discharged through the UV glue 5 in the liquid state above. After the mold box 2 is preliminarily cured in the first curing chamber 20, it is then placed in the second curing chamber 30 for deep curing. The second chamber body 31 can be used to install the second curing box bracket 32, the second UV light source 33, and the third UV light source 34. The second chamber body 31 can be integrally formed by the internal structure of the frame body 10. Of course, in order to facilitate the installation of the second curing box bracket 32, the second UV light source 33, and the third UV light source 34, the second chamber body 31 can be configured separately and then installed on the frame body 10.Since in the second curing chamber 30, a second UV light source 33 is provided below the second curing cartridge carrier 32, and a third UV light source 34 is also provided above it. Of course, a UV light source can also be provided at the side position of the second curing cartridge carrier 32, so that the UV glue in the mold box 2 can be fully irradiated, completely reacted, fully cured, and the curing efficiency is improved. For the metallographic section 1 with the target hole 3, the mold box 2 can be horizontally placed in the second curing cartridge carrier 32. If the mold box 2 is placed vertically, it is difficult for the target hole 3 to be irradiated by the UV light source. However, when the mold box 2 is placed horizontally, the ultraviolet rays emitted by the second UV light source 33 and the third UV light source 34 can both irradiate the target hole 3 on the metallographic section 1, ensuring that the UV glue in the hole cavity is also completely cured, achieving the purpose of deep curing. As long as the mold box 2 is placed horizontally, since there are UV light sources above and below the second curing cartridge carrier 32, whether the front of the mold box 2 faces down or up will not affect the curing effect, greatly improving the curing efficiency. Optionally, a first button switch 11 is further provided on the frame body 10, which is electrically connected to the first curing chamber 20 and is used to control the operation of the first curing chamber 20, that is, the first button switch 11 can control the operation of the first UV light source 23; optionally, a second button switch 12 is further provided on the frame body 10, which is electrically connected to the second curing chamber 30 and is used to control the operation of the second curing chamber 30, that is, the second button switch 12 can control the operation of the second UV light source 33 and the third UV light source 34.

[0050] As an alternative embodiment, refer to Figure 4 , the curing machine 100 further includes a curing cartridge 221, the curing cartridge 221 is detachably connected to the first curing cartridge carrier 22 or the second curing cartridge carrier 32, the curing cartridge 221 is provided with at least one receiving groove 2211 for receiving the mold box 2, and a hollow area 2212 is provided at the bottom of the receiving groove 2211; the shape of the receiving groove 2211 is configured to be adapted to the shape of the mold box 2 when the first opening 4 faces upward.

[0051] In this embodiment, when the first curing chamber 20 is used for preliminary curing, the curing cartridge 221 can be placed on the first curing cartridge carrier 22 (refer to Figure 3) Place the first opening 4 of the mold box 2 facing upwards in the receiving groove 2211 to prevent the liquid UV glue in the mold box 2 from pouring out and to facilitate the discharge of heat and air bubbles through the first opening 4 during preliminary curing, thereby reducing the generation of air bubbles. A hollow area 2212 is provided at the bottom of the curing box 221 so that the ultraviolet light emitted by the first UV light source 23 can irradiate the mold box 2 in the receiving groove 2211 from below. The shape of the receiving groove 2211 is adapted to the shape of the first opening 4 of the mold box 2 when it is facing upwards, so that the mold box 2 placed therein can be positioned by the receiving groove 2211 to prevent it from tipping over. After the preliminary curing is completed, when using the second curing chamber 30 for deep curing, if there is no target hole in the metallographic section, the curing box 221 can be taken out from the first curing box bracket 22 and placed on the second curing box bracket 32. For the case of having multiple mold boxes 2, the operation process of taking out or putting in the mold boxes 2 can be reduced, saving time.

[0056] In this embodiment, when the first curing chamber 20 is used for preliminary curing, the first curing cassette carrier 22 can be withdrawn from the first chamber body 21 to facilitate placing the mold cassette 2 into the first curing cassette carrier 22. After placement, when the first curing cassette carrier 22 is pushed into the first chamber body 21, the first chamber body 21 can be closed through the first sealing ring 212 to improve the vacuum pumping effect of the vacuum pump 45. When the second curing chamber 30 is used for deep curing, the second curing cassette carrier 32 can be withdrawn from the second chamber body 31 to facilitate placing the mold cassette 2 into the second curing cassette carrier 32. After placement, the second curing cassette carrier 32 is pushed into the second chamber body 31.

Multiple light-emitting light sources can be provided for the UV light source, and the light-emitting light sources can be arranged corresponding to the respective receiving slots of the curing cassette to uniformly emit ultraviolet light into each receiving slot.

[0061] As an alternative embodiment, a light-transmitting frosted glass 25 for converting the light emitted by the first UV light source 23 into light with uniform intensity is provided between the first curing cassette carrier 22 and the first UV light source 23 (see Figure 5 );

[0062] A first light-transmitting glass 35 is provided between the second curing cassette carrier 32 and the second UV light source 33 (see Figure 7 ); The first light-transmitting glass 35 is provided at the bottom of the second curing cassette carrier 32 (see Figure 6 and Figure 7 ); The mold cassette 2 can be directly placed on the first light-transmitting glass 35; (see Figure 7 )

[0064] In this embodiment, the light-transmitting frosted glass 25 is made of frosted glass material; the first light-transmitting glass 35 and the second light-transmitting glass 36 can be made of glass material. The light emitted by the UV light source forms a beam with uniform intensity after passing through the light-transmitting frosted glass 25, so that the beam uniformly enters the first curing box bracket 22, so that each part of the mold box 2 in the first curing box bracket 22 is uniformly illuminated and uniformly heated, reducing the generation of bubbles.

[0065] As an alternative embodiment, referring to Figure 9 , the curing machine 100 further includes a glue pool 40 for loading the UV glue 5 and a vibration motor 50; the glue pool 40 is arranged on the frame body 10, and the bottom of the glue pool 40 is connected to the vibration motor 50.

[0066] In this embodiment, before putting the metallographic section 1 into the mold box 2, the metallographic section 1 can be first put into the glue pool 40. The vibration motor 50 can drive the glue pool 40 to vibrate. Under the action of vibration, the metallographic section 1 can be more fully wrapped by the UV glue 5, filling the gaps and reducing the generation of bubbles. Optionally, a third push-button switch 13 is further arranged on the frame body 10, which is electrically connected to the vibration motor 50 and used to control the operation of the vibration motor 50.

The first flash curing UV lamp 60 is arranged on the frame body 10, and the first momentary button 61 is electrically connected to the first flash curing UV lamp 60.

[0070] In this embodiment, after the metallographic slice 1 is taken out of the glue pool 40 and placed in the mold box 2, it can be flash-cured by a flash-curing UV lamp. The UV glue 5 is slightly hardened due to the irradiation of the flash-curing UV lamp to fix the metallographic slice 1 in the mold box 2 to prevent the metallographic slice 1 from moving in the subsequent operation. The first flash-curing UV lamp 60 is provided with a UV-LED lamp bead that can emit ultraviolet light. The first inching button 61 is used to control the operation of the first flash-curing UV lamp 60, see Figure 13 The user places the mold box 2 on the first flash curing UV lamp 60 and presses the first inching button 61. The first flash curing UV lamp 60 lights up and emits ultraviolet light, and the flash curing is completed.

[0071] As an alternative embodiment, see Figure 11 , Figure 12 as well as Figure 14 The curing machine 100 also includes a stage 70, a second flash curing UV lamp 80, a second momentary button 81 and an enlarged display device 90; the stage 70 is arranged on the frame body 10, and a positioning groove 71 adapted to the mold box 2 is arranged on the stage 70; the second flash curing UV lamp 80 is arranged toward the positioning groove 71 of the stage 70, and the light emitted by the second flash curing UV lamp 80 passes through the mold box 2 on the positioning groove 71; the second momentary button 81 is electrically connected to the second flash curing UV lamp 80; the enlarged display device 90 is used to obtain the image of the metallographic section 1 in the mold box 2 on the positioning groove 71, and enlarge the display.

[0072] Specifically, the magnifying display device 90 includes a reflector 91, a lens 92, a CCD (charge coupled device) camera 93 and a display 94; the CCD camera 93 is electrically connected to the display 94; the reflector 91 reflects the metallographic section 1 in the mold box 2 to the lens 92; the lens 92 projects the image of the metallographic section 1 in the mold box 2 to the CCD camera 93, the CCD camera 93 magnifies the image of the metallographic section 1 in the mold box 2 and sends it to the display 94, and the display 94 displays the magnified image of the metallographic section 1 in the mold box 2.

[0073] In this embodiment, when the metallographic section 1 is taken out of the glue pool 40 and placed into the mold box 2, for the standard-sized metallographic section 1, it is used in conjunction with the mold box 2. When the standard-sized metallographic section 1 is placed into the mold box 2, due to the positioning effect of the internal structure of the mold box 2 on the metallographic section 1, the metallographic section 1 is in a correct position when placed into the mold box 2. For the smaller-sized metallographic section 1, when one or more metallographic sections 1 are placed into the mold box 2, due to its small size, it cannot be positioned by relying on the internal structure of the mold box 2. In order to accurately position it correctly, a magnifying display device 90 is needed. Specifically, the mold box 2 containing the metallographic section 1 is placed on the stage 70. The stage 70 is made of a transparent material. The CCD camera 93 is used to magnify and display the metallographic section 1 and the mold box 2 on the display 94, facilitating the user to adjust the position of the metallographic section 1 with tweezers. The second flash curing UV lamp 80 is used in conjunction with the magnifying display device 90. For the metallographic section 1 that needs to be adjusted using the magnifying display device 90, after the adjustment, the second momentary button 81 can be directly pressed once, causing the second flash curing UV lamp 80 to light up once, and the flash curing is completed. The second flash curing UV lamp 80 is provided with UV-LED lamp beads, which can emit ultraviolet light. Through the setting of the reflecting mirror 91, the position of the magnifying display device 90 can be flexibly set, so that the lens 92 of the magnifying display device 90 can obtain an image of the metallographic section 1 in the mold box 2 without directly aiming at the mold box 2.

[0074] An example of the usage process of the curing machine 100 is as follows:

[0075] Pour the pre-uniformly configured UV glue 5 without pungent odor into the glue pool 40, place the metallographic section 1 into the glue pool 40 for soaking, and start the third button switch 13. The third button switch 13 can control the vibration motor 50 to start working. Of course, the third button switch 13 can also be set to control the vibration motor 50 and the vacuum pump 45 simultaneously. If different button switches are used separately, the vibration motor 50 and the vacuum pump 45 can be controlled more flexibly. Under the action of the vibration motor 50 and the vacuum pump 45, the air bubbles between the metallographic section 1 and the UV glue 5 can be reduced, and the metallographic section 1 is fully wrapped by the UV glue 5;

[0076] Place the metallographic section 1 fully wrapped by the UV glue 5 into the mold box 2. If the metallographic section 1 is of standard size, it is directly placed into the mold box 2, and the mold box 2 is placed above the first flash curing UV lamp 60 for flash curing, so that the metallographic section 1 is fixed in the mold box 2. If the size of the metallographic section 1 is small, after it is loaded into the mold box 2, it is placed on the stage 70, positioned through the positioning groove 71 of the stage 70, and then the image of the mold box 2 is magnified and displayed through the magnifying display device 90. After the user observes the magnified and displayed image, the position of the metallographic section 1 can be adjusted with tools such as tweezers. After the adjustment, without moving the mold box 2, the second flash curing UV lamp 80 is directly used to flash cure the mold box 2.

[0077] After flash curing is completed, fill the mold box 2 with UV glue 5, vertically place it in the first curing box 221, place the curing box 221 on the first curing box bracket 22, push the first curing box bracket 22 into the first cabin 21, and start preliminary curing. Press the first button switch 11, the first UV light source 23 is started, and the vacuum pump 45 is started synchronously until the preliminary curing is completed.

[0078] After the preliminary curing is completed, if there is no target hole 3 on the metallographic section 1, take out the curing box 221 from the first curing box bracket 22 and place it on the second curing box bracket 32, push the second curing box bracket 32 into the second cabin 31, and start deep curing. If there is a target hole 3 on the metallographic section 1, take out the mold box 2 from the curing box 221 and horizontally place it on the first light-transmitting glass 35 on the second curing box bracket 32. Start the second button switch 12, and the second UV light source 33 and the third UV light source 34 start to work until the deep curing is completed.

[0079] In summary, the curing machine of the utility model is provided with a first curing cabin and a second curing cabin; the first curing cabin is used for preliminary curing, and includes a first cabin body, a first curing box bracket, a first UV light source and a light absorbing cover; the first UV light source is arranged below the first curing box bracket; the light absorbing cover is arranged above the first curing box bracket; the mold box loaded with metallographic sections and filled with UV glue is placed vertically in the first curing box bracket, that is, the first opening of the mold box is placed upward. Optionally, the curing box is detachably connected to the first curing box bracket, and the shape of the receiving groove on the curing box is configured to match the shape of the first opening of the mold box when it is facing upward. Placing the mold box in the receiving groove can keep the first opening of the mold box facing upward, and it is not easy to tip over, and the light from below can be irradiated into the mold box through the hollow area provided in the receiving groove. In the first curing chamber, only the first UV light source is provided below the first curing box bracket, while there is no UV light source above the first curing box bracket, and a light absorbing cover is also provided above it to prevent the ultraviolet light irradiated from below from irradiating the UV glue above by reflection, so as to ensure that the UV glue below must be cured before the UV glue above. Therefore, in the first curing chamber, the UV glue is cured from the bottom of the mold box, and the heat generated during the curing process is discharged through the liquid UV glue above, and the generated bubbles can also be discharged through the liquid UV glue above. During the curing process, the first cabin can be evacuated at the same time, and the evacuation accelerates the heat dissipation and bubble discharge process. There is a closed light-transmitting frosted glass between the first UV light source below and the first curing box bracket, which can convert the light emitted by the first UV light source into light with uniform intensity, so that the UV glue of the mold box in the first curing box bracket is evenly illuminated and heated, so as to reduce the generation of bubbles. The function of the second curing chamber is deep curing. After the mold box is initially cured in the first curing chamber, the mold box can be placed in the second curing box bracket. Optionally, if the metallographic section has no target hole, the curing box on the first curing box bracket can be removed and placed in the second curing box bracket, saving the operation process of taking out or putting in the mold box. Since a second UV light source is arranged below the second curing box bracket in the second curing chamber, and a third UV light source is arranged above it, the UV glue in the mold box can be fully irradiated, fully reacted, and fully cured, and the curing efficiency is improved. For metallographic sections with target holes, the mold box can be placed horizontally in the second curing box bracket. If the mold box is placed vertically, the target hole is difficult to be irradiated by the UV light source. If the mold box is placed horizontally, the ultraviolet light emitted by the second UV light source and the third UV light source can irradiate the target hole on the metallographic section, ensuring that the UV glue in the hole cavity is also fully cured, achieving the purpose of deep curing. As long as the mold box is placed horizontally, since there are UV light sources above and below the second curing box bracket, whether the front of the mold box is facing down or up will not affect the curing effect, which greatly improves the curing efficiency.

Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
