Description

Technical Field

[0001] This application relates to the field of colloid detection technology, and in particular to a colloid sample preparation device. Background Technology

[0002] The junction box in a photovoltaic module has excellent insulation properties, sealing the module's leads. Its connectors also feature a self-locking function, making electrical connections between the solar panel and the module more convenient and reliable, thus enhancing the module's safety. Sealing the junction box can be achieved by injecting sealant. Therefore, the curing effect of the sealant needs to be inspected. Traditionally, sealant is directly poured into a measuring cup, and the curing effect is checked by visual inspection. After a certain curing time, the cured sealant needs to be removed and cut to examine its internal curing. However, the cured sealant has a certain elasticity, forming a tight bond with the measuring cup, making it difficult to directly remove the sealant for testing. Utility Model Content

[0032] In traditional colloid curing testing, the colloid is directly cured into a measuring cup. Once cured, the colloid adheres tightly to the inner wall of the measuring cup, making it difficult to remove for testing due to the cup's structure. Therefore, the operator uses a utility knife or screwdriver to reach the bottom of the colloid along the inner wall of the measuring cup and uses leverage to separate it. However, this process easily damages the colloid, affecting its testing accuracy.

[0033] Based on this, this application provides a gel sample preparation device, such as... Figure 1 As shown, the gelatinous sample preparation device includes a barrel 100 and an inner liner 200. Among them, as... Figure 2 As shown, the inner liner 200 includes a base 210 and a liner wall 220 disposed on the edge of the base 210. The base 210 has at least one first perforation. The inner liner 200 can be detachably nested inside the barrel 100, and the base 210 is fitted to the bottom of the barrel, while the liner wall 220 is fitted to the inner wall of the barrel 100.

[0034] This application incorporates an inner liner 200 within a barrel 100. During sample preparation and testing, the adhesive is poured into the barrel 100 containing the inner liner 200 for curing. Once the adhesive has cured, the inner liner 200 is removed from the barrel 100, simultaneously carrying the cured adhesive with it. Force is then applied to the cured adhesive through a first perforation to remove it from the inner liner 200. This application facilitates the removal of the cured adhesive sample without causing damage.

[0035] It is understood that the shape of the barrel 100 in this application can be reasonably selected according to the shape of the sample. For example, the shape of the barrel 100 can be cylindrical or frustum-shaped. Meanwhile, the base 210 of this application serves to carry the cured colloid out of the barrel 100; the first perforated hole facilitates the operator to apply pressure to the cured colloid through the base 210, thereby detaching the colloid from the inner liner 200. Therefore, the first perforated hole needs to have a certain area to facilitate the application of force and ensure that the colloid is not unable to be carried out during the removal of the inner liner 200. For example, the shape of the first perforated hole in this application can be fan-shaped, circular, or polygonal.

[0036] It should be noted that the detachable arrangement of the inner liner 200 and the barrel 100 in this application means that the inner liner 200 can be placed in the barrel 100 or removed from the barrel 100; the inner liner 200 is not fixed in the barrel 100. Specifically, to ensure that the shape of the formed colloid sample is the same as the shape of the barrel 100, the liner wall 220 of the inner liner 200 can be fitted against a portion of the inner wall of the barrel 100, and the base 210 can be fitted against a portion of the bottom of the barrel 100. Alternatively, a groove is formed on the inner wall of the barrel 100 that engages with the liner wall 220, and a groove is formed on the bottom of the barrel 100 that engages with the base 210. In other words, when the inner liner 200 is placed in the barrel 100, the liner wall 220 and the base 210 fit into the grooves in the barrel 100, so that the shape of the formed colloid is the same as the shape of the barrel 100.

[0037] In some embodiments, such as Figure 4 As shown, the base 210 is composed of multiple base plates 211 spaced apart around the center of the base 210. The interval between adjacent base plates 211 is the first perforation. During the removal process, the operator can rotate the liner to completely separate the bottom of the colloid from the bottom of the barrel 100, thus facilitating the removal of the liner 200 from the barrel 100. The base plates 211 are spaced apart and not connected. Therefore, when the material of the base plates 211 has a certain degree of toughness, the difficulty of removing the colloid can be further reduced by pressing the base plates 211 into the first perforation during the removal process.

[0038] Optionally, the base plate 211 can be fan-shaped. The base 210 is composed of multiple spaced-apart fan-shaped sections, forming a fan-shaped first perforation. Further optionally, the number of base plates 211 can be 2, 3, 4, or 5. The fan-shaped base plates 211 have the same shape and area as the first perforation, meaning the base plates 211 and the first perforation evenly divide the circular bottom of the barrel 100.

[0039] In some embodiments, the thickness of the base plate 211 gradually decreases from the center to the edge. This application reduces the edge thickness of the base plate 211, giving it a blade-like structure. When the inner liner 200 is rotated, the blade-like edge of the base plate 211 more easily separates the colloid from the bottom of the barrel 100. This application effectively reduces the problem of tearing damage caused by the colloid adhering to the barrel 100 when the inner liner 200 is rotated.

[0040] It is understood that the thickness of the base plate 211 in this application can be selected according to actual needs. The base plate 211 should have a certain strength to carry out the colloid without structural damage. In addition, the blade-like structure can be set only at the edge of the base plate 211, while the other parts of the base plate 211 can naturally be flat to ensure the structural strength of the base plate 211.

[0041] In some embodiments, at least one second perforation is provided on the liner 220. The provision of multiple second perforations not only reduces the bonding area between the adhesive and the liner 220, but also applies force to the exposed adhesive on the liner 220 during adhesive removal. The synergistic cooperation between the second and first perforations reduces the difficulty of separating the adhesive from the inner liner 200.

[0042] It is understood that the second perforation in this application only needs to facilitate the separation of the colloid. Optionally, the shape of the second perforation in this application can be fan-shaped, circular, or polygonal. The larger the area of ​​the second perforation, the larger the exposed colloid portion, thus facilitating the separation of the colloid from the inner liner 200. For example, the second perforation can be formed from the bottom of the liner 220 near the barrel 100 to the top of the barrel 100, exposing most of the colloid, with the exposed area reaching more than half of the colloid's side area.

[0043] It should be noted that, even with a perforated structure, the inner liner 200 can still form the desired colloid during the colloid formation process, constrained by the barrel 100. Therefore, the main function of the liner 220 is to facilitate the removal of the base 210 from the inner liner 200. In other words, the liner 220 has sufficient strength to maintain a stable connection with the base 210, allowing the inner liner 200 to be removed.

[0044] In some embodiments, such as Figure 3As shown, the liner 220 is composed of multiple liner plates 221 spaced circumferentially along the base 210, with a second perforation between adjacent liner plates 221. With the liner plates 221 arranged as described above, during the removal of the inner liner 200, the inner liner 200 can be rotated to detach the side of the colloid from the barrel 100, facilitating removal of the inner liner 200. Furthermore, a larger area of ​​the colloid is exposed within the inner liner 200, further aiding in colloid detachment.

[0045] Optionally, the liner 221 can be a rectangular plate arranged along the height direction of the barrel 100, thereby forming a rectangular second perforation between two adjacent liner plates 221. It is understood that the larger the interval between two liner plates 221, the larger the area of ​​the second perforation, making it easier for the colloid to be removed from the inner liner 200.

[0046] In some embodiments, the thickness of the liner 221 gradually decreases from the center to the edge of the liner 221. This application reduces the edge thickness of the liner 221, making the edge of the liner 221 have a blade-like structure. Therefore, when the inner liner 200 is rotated, the blade-like edge of the liner 221 can more easily separate the colloid from the side wall of the barrel 100, reducing the risk of tearing and damage to the colloid when removing the inner liner 200.

[0047] It is understood that in this application, a blade-like structure can be formed just outside the edge of the liner 221, while the remaining portion can still be a flat plate structure. This ensures the structural strength of the liner 221.

[0048] In some embodiments, at least a portion of the liner 220 protrudes from the barrel body 100. This application involves at least a portion of the liner 220 protruding from the barrel body 100, exposing a portion of the liner 220 to the outside of the barrel body 100. During the removal of the inner liner 200, the portion of the liner 220 protruding from the barrel body 100 can be directly grasped, facilitating the removal of the inner liner 200 from the barrel body 100.

[0049] Furthermore, this application may also provide a handle for easy gripping on the portion of the liner 220 protruding from the barrel 100. Alternatively, a friction structure may be provided on the portion of the liner 220 protruding from the barrel 100 to increase friction. This facilitates the removal of the inner liner 200 from the barrel 100.

[0050] In some embodiments, a first anti-adhesive layer is provided on the surface of the base 210. A second anti-adhesive layer is provided on the surface of the liner 220. It is understood that the first and second anti-adhesive layers serve to reduce the adhesion between the adhesive and the inner liner 200, thereby facilitating the removal of the adhesive from the inner liner 200.

[0051] Understandably, the materials for the first and second anti-adhesive layers can be selected based on the type of sealant. For example, the materials for both the first and second anti-adhesive layers can be polypropylene (PP).

[0052] Furthermore, a third anti-stick layer is provided on the inner wall of the barrel 100. This reduces the adhesion between the adhesive and the barrel 100, making it easier for the adhesive to detach from the barrel 100.

[0053] In some embodiments, such as Figure 3 As shown, the inner liner 200 also includes a support plate 230. The support plate 230 is disposed on the side of the liner wall 220 away from the base 210, and is arranged circumferentially along the inner liner 200. Optionally, the support plate 230 is an annular plate extending circumferentially along the inner liner 200. This application uses the support plate 230 to support the liner wall 220, preventing deformation of the liner wall 220 and affecting the shape of the rubber sample.

[0054] The annular plate can be located on the side of the liner 220 away from the center of the barrel 100, or it can be located on the side of the liner 220 closer to the center of the barrel 100. When the annular plate is located on the side of the liner 220 away from the center of the barrel 100, it is convenient to remove the colloid from the inner liner 200.

[0055] In some embodiments, the liner 220 and the support plate 230 are flexibly connected. It should be noted that, in this application, "flexible connection" means that the liner 220 can be angled within a certain range, thereby improving the separation effect between the liner 220 and the colloid by pressing and shaking the liner 221. Optionally, the flexible connection can be achieved by providing a thinning structure 222 at the connection point of the liner 221 near the support plate 230. The thinning structure 222 refers to the fact that the thickness of the liner 221 at this location is smaller than the thickness at other locations, thus providing better flexibility compared to other areas. Alternatively, a rotating shaft structure or similar can be provided at the connection point to allow relative rotation between the liner 220 and the support plate 230.

[0056] Optionally, the liner 221 is connected to the base plate 211 in a one-to-one correspondence, and each liner 221 is flexibly connected to the support plate 230. Since the base 210 of this application is formed by multiple spaced and unconnected base plates 211, they are flexibly connected to the support plate 230 in conjunction with the liner 221. During the removal of the colloid from the inner liner 200, the liner 221 is adjusted away from the colloid under the action of the flexible connection, causing the colloid to peel off from the liner wall 220, and the base plates 211 to separate from each other. After separation, the colloid can be directly removed from one side of the base 210 of the inner liner 200, further improving sample preparation efficiency without damaging the colloid.

[0057] Alternatively, the edge of the base plate 211 near the center may be rounded. For example, the base plate 211 may have a fan-shaped ring structure. This avoids a sharp angle on the side of the base plate 211 facing the center, thereby preventing scratches from occurring during the removal of the colloid from the bottom of the liner 200.

[0058] In some embodiments, the barrel 100 may be frustum-shaped, wherein the bottom diameter of the barrel 100 is 3cm~3.4cm, the mouth diameter is 3.5cm~3.9cm, the height is 3.5cm~3.9cm, and the wall thickness is 0.5mm~1mm. Correspondingly, the inner lining 200 is tightly fitted to the barrel 100, the thickness of its bottom plate 211 is 0.5mm~1mm, and the height of its lining wall 220 is 5.5cm~5.9cm.

[0059] By way of example, a method for preparing sealant samples using the above-described sealant sample preparation apparatus is provided, comprising the following steps:

[0060] S1. Place the inner liner 200 inside the barrel 100 and pour the adhesive to be tested into the barrel 100 for curing.

[0061] S2. During the curing period, the curing process of the colloid inside the barrel can be observed.

[0062] S3. After the curing time is met, remove the inner liner 200 from the barrel 100, and at the same time, the inner liner 200 will carry the colloid out of the barrel 100. It can be understood that the inner liner 200 can be rotated during the removal process, so that the inner liner 200 and the barrel 100 rotate relative to each other, thereby allowing the colloid to be fully separated from the barrel 100.

[0063] S4. After removing the inner liner 200, apply force to the first perforation on the base 210 of the inner liner 200 to remove the colloid from the inner liner 200. If the liner wall 220 of the inner liner 200 has a second perforation, force can be applied to the exposed colloid through the second perforation to separate the colloid from the liner wall 220, making it easier to remove the colloid from the inner liner 200.

[0064] Furthermore, if the base 210 includes multiple spaced-apart base plates 211 that are not connected to each other, and the liner 220 includes multiple spaced-apart liners 221, and the liners 221 are flexibly connected to the support plate 230, then the angle of the liners 221 can be adjusted to separate and open the base plates 211, thereby allowing the colloid to be removed from the bottom of the inner liner 200.

[0065] In summary, this application incorporates an inner liner 200 within the barrel 100. During sample preparation and testing, the adhesive is poured into the barrel 100 containing the inner liner 200 for curing. Once the adhesive has cured, the inner liner 200 is removed from the barrel 100, simultaneously carrying the cured adhesive with it. Then, force is applied to the cured adhesive through the first perforation to remove it from the inner liner 200. This application facilitates the removal of the cured adhesive sample without causing damage.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
