Description

Technical Field

[0001] This application relates to the technical field of sealant product performance testing, and particularly to a sealant specimen preparation device. Background Art

[0002] In terms of sealant product performance testing, in order to investigate its various performances, it is usually necessary to make the sealant into specimens of fixed sizes, such as cubes, strips or flat plates, etc. At the same time, it is necessary to ensure that the surfaces of the made specimens are flat, smooth and clean.

[0003] In the existing specimen preparation methods, usually a frame of corresponding shape is made of hard materials such as plastics or metals, and then the frame is placed on the surface of a base material such as a mortar board or a glass plate. After that, an excessive amount of sealant is squeezed into the frame by manually pressing a glue gun. After ensuring that the sealant fills the frame sufficiently, a spatula or a scraper can be used to scrape off the excess sealant protruding from the outer surface of the frame, thus completing the preparation of the specimen.

[0004] However, during actual operation, due to the strong viscosity of the sealant, it is extremely easy to contaminate any position touched by the spatula or the scraper, and the cleaning is extremely troublesome. Moreover, due to its strong adhesion characteristics, during the scraping process, it can only be scraped flat at one time and cannot be repeatedly trimmed, resulting in a relatively large difficulty in overall sealant scraping, and thus it is more difficult to make specimens that meet the requirements, and the efficiency of repeated plate making is relatively low; in addition, the scraped excess sealant cannot be reused, which is likely to cause relatively large waste. Summary of the Utility Model

[0005] In order to achieve the purpose of improving the efficiency of repeated preparation while ensuring that the surface of the made specimen is smooth and flat, and at the same time reducing the waste of sealant, this application provides a sealant specimen preparation device.

[0006] A sealant specimen preparation device provided by this application adopts the following technical solutions:

[0007] A sealant specimen preparation device includes a frame. A 3D printer for 3D printing a box-shaped mold with an opening at one end facing the base material is arranged on the frame. A clamping mechanism for clamping and fixing the box-shaped mold, a glue injection mechanism for injecting sealant into the box-shaped mold, and an air injection separation mechanism for separating the box-shaped mold from the sealant specimen are arranged on the frame.

[0008] By adopting the above technical solution, during use, first place the substrate on the printing platform of the 3D printer, and then use the 3D printer to 3D print a cassette mold with a specified size and shape, that is, a rectangular box with one end open and the opening facing the substrate. At the same time, a glue injection port is formed on the side wall of the cassette mold. After printing is completed, the cassette mold is clamped and fixed on the substrate by the clamping mechanism. Then, the injection mechanism injects a sufficient amount of sealant into the cassette mold from the glue injection port until the inner cavity of the cassette mold is filled with the sealant, and then the injection mechanism can be withdrawn. Finally, the sealant and the cassette mold are separated by the gas injection separation mechanism. After the cassette mold is removed, the preparation of the sealant specimen can be completed. Compared with the prior art that relies on manual preparation, on the one hand, it ensures that the surface of the prepared sealant specimen is clean, smooth and flat, and the preparation process is simple, fast and efficient. On the other hand, it reduces the waste of sealant and is more conducive to use.

[0009] Preferably, a fixing plate is arranged on the platform of the 3D printer, and a positioning groove for embedding and positioning the substrate is opened on the fixing plate.

[0010] By adopting the above technical solution, during use, install the fixing plate on the printing platform of the 3D printer, then place the substrate into the positioning groove, and position the substrate through the positioning groove to avoid the substrate moving during subsequent printing or glue injection.

[0011] Preferably, the clamping mechanism includes a first clamping block slid on the frame and a first driving cylinder for driving the first clamping block to move towards or away from the cassette mold. The cylinder body of the first driving cylinder is fixed on the frame, and the end of the piston rod of the first driving cylinder is fixedly connected to the first clamping block. There are two groups of the first clamping block and the first driving cylinder, and the two groups of the first clamping block and the first driving cylinder are arranged oppositely on both sides of the positioning groove.

[0012] By adopting the above technical solution, after the cassette mold is made, the piston rods of the two first driving cylinders can be driven to extend synchronously, so as to drive the two first clamping blocks to slide synchronously until they abut against the side wall of the cassette mold, and the clamping and positioning of the cassette mold can be realized.

[0013] Preferably, buffer layers are arranged on the opposite surfaces of the two first clamping blocks.

[0014] By adopting the above technical solution, during use, by setting the buffer layer, the first clamping block is prevented from directly contacting the cassette mold, so as to reduce the clamping force when the first clamping block clamps the side wall of the cassette mold, thereby avoiding damage to the cassette mold.

[0015] Preferably, the clamping mechanism includes two second clamping blocks slidably arranged on the frame, a sliding sleeve fixed on the second clamping blocks, a bidirectional lead screw rotatably arranged on the frame, and a driving motor for driving the bidirectional lead screw to rotate. The two second clamping blocks are oppositely arranged on both sides of the positioning groove. The two sliding sleeves are respectively threadedly connected to one side of the bidirectional lead screw, and the driving motor is installed on the frame.

[0016] By adopting the above technical solution, during use, when the cassette mold is made, the driving motor is used to drive the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw synchronously drives the two sliding sleeves to slide towards each other, thereby driving the two second clamping blocks to slide towards each other. Until both second clamping blocks abut against the side wall of the cassette mold, the clamping and fixing of the cassette mold can be achieved.

[0017] Preferably, the glue injection mechanism includes a mounting seat slidably arranged on the frame, a second driving cylinder installed on the frame, and an electric glue injector detachably connected to the mounting seat. The second driving cylinder is used to drive the mounting seat to slide and drive the glue outlet of the electric glue injector to insert into the cassette mold.

[0018] By adopting the above technical solution, when the cassette mold is made and fixed, the piston rod of the second driving cylinder extends to drive the mounting seat to slide, thereby driving the electric glue injector close to the cassette mold. Until the glue outlet on the electric glue injector inserts into the glue injection port on the cassette mold, the sealant can be injected into the inner cavity of the cassette mold through the electric glue injector. When the cassette mold is filled with sealant, the piston rod of the second driving cylinder retracts to drive the electric glue injector away from the glue injection port, thereby completing the glue injection; under the shape limitation of the inner wall of the cassette mold and the substrate, it ensures that the outer surface of the sealant specimen is smooth, flat and tidy after molding, and at the same time reduces the easy waste situation during the sealant filling process.

[0019] Preferably, the mounting seat includes a base slidable on the frame and a vertical plate fixed on the base. There are two vertical plates, and the two vertical plates are oppositely arranged on the base. The vertical plate is provided with a clamping groove for clamping and embedding the electric glue injector, and the vertical plate is also provided with a limiting groove for limiting the glue outlet of the electric glue injector. The limiting groove communicates with the clamping groove.

[0020] By adopting the above technical solution, during use, through the combined use of the clamping groove and the limiting groove, the detachable connection between the electric glue injector and the mounting seat is realized, which is convenient for replacing or cleaning parts such as the glue nozzle and pipeline of the electric glue injector, and is convenient for injecting different types of sealants.

[0021] Preferably, the gas injection and separation mechanism includes a fixing frame fixed on the frame, and an air blowing gun arranged on the fixing frame, an air duct is arranged at one end of the air blowing gun, a control valve for controlling the ventilation of the air duct is arranged on the air duct, the air duct is connected to an external air path at one end away from the air blowing gun, a storage groove is opened on the fixing frame, and the air blowing gun is placed in the storage groove.

[0022] By adopting the above technical scheme, when the box-type mold is filled with sealant, after the sealant has been cured for one day, the staff will take out the air blow gun and insert the air blow gun into the injection port. After that, the control valve can be opened to connect the external air path, the air guide pipe and the air blow gun, so that air can be blown into the box-type mold through the air blow gun, so that the box-type mold and the sealant test piece are gradually separated. Finally, the box-type mold can be slowly taken out to complete the preparation of the sealant test piece. It is simple and convenient to use.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the coordinated use of the 3D printer, the clamping mechanism, the glue injection mechanism and the gas injection separation mechanism, the efficiency and convenience of the overall preparation process are improved while ensuring that the surface of the sealant specimen after manufacture is neat, smooth and flat. At the same time, compared with the manual preparation method, the waste of sealant in the preparation process is also reduced;

[0025] 2. When in use, two groups of first driving cylinders are used to drive a corresponding first clamping block to slide toward each other, thereby clamping and fixing the cassette mold, thereby ensuring the stability of the cassette mold during the subsequent glue injection process, and further ensuring that the glue injection mechanism will not separate from the cassette mold during the glue injection process;

[0026] 3. After curing the sealant for one day, blow air into the box mold through an air gun to slowly separate the sealant specimen from the inner wall of the box mold, thereby ensuring that the surface of the manufactured sealant specimen is flat, smooth and neat, thereby ensuring the preparation quality of the sealant specimen.

Detailed implementation manners

[0036] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 8 drawings.

[0037] The embodiment of the present application discloses a sealing glue specimen preparation device.

[0038] Embodiment 1:

[0039] Referring to Figure 1 and Figure 2 , a sealing glue specimen preparation device includes a horizontally placed frame 1, a 3D printer 2 is placed on the frame 1, a fixing plate 6 is fixed on the printing platform of the 3D printer 2 by bolts, and a positioning groove 61 is formed through the fixing plate 6. The positioning groove 61 is used to embed the base material 7 to position the base material 7 at a specified position; during use, first, a staff member presents a box-shaped mold 8 with a specified shape in three-dimensional model modeling, then imports the data of the three-dimensional model into the 3D printer 2, and then places the base material 7 made of mortar board or glass plate into the positioning groove 61, and the 3D printer 2 can directly print the box-shaped mold 8 with the specified shape and size on the base material 7.

[0040] Referring toFigure 1 and Figure 2 In the embodiment of the present application, the cassette mold 8 is in the shape of a rectangular box with an open bottom surface, and a glue injection port 9 is integrally formed on the side wall of the cassette mold 8; a clamping mechanism 3, a glue injection mechanism 4 and a gas injection and separation mechanism 5 are arranged on the frame 1, wherein the glue injection mechanism 4 is located on the side of the cassette mold 8 where the glue injection port 9 is opened, and the clamping mechanism 3 and the gas injection and separation mechanism 5 are spaced apart and distributed on the periphery of the 3D printer 2.

[0041] Referring to Figure 1 and Figure 3 The clamping mechanism 3 is used for clamping and positioning the formed cassette mold 8. The clamping mechanism 3 is composed of two groups of first clamping blocks 31 and two groups of first driving cylinders 32. The first clamping blocks 31 and the first driving cylinders 32 are arranged in one-to-one correspondence. The first clamping blocks 31 are slidably arranged on the frame 1, and the sliding direction of the first clamping blocks 31 is the direction of approaching or departing from the cassette mold 8. The two groups of first clamping blocks 31 are oppositely arranged on both sides of the cassette mold 8. The cylinder block of the first driving cylinder 32 is fixed on the frame 1, and the piston rod of the first driving cylinder 32 is bolted and fixed to the first clamping block 31.

[0042] Referring to Figure 1 and Figure 3 During use, when the printing of the cassette mold 8 is completed, air can be simultaneously introduced into the two first driving cylinders 32, so that the piston rods of the two first driving cylinders 32 extend synchronously, thereby driving the corresponding first clamping blocks 31 to slide towards each other until the two first clamping blocks 31 simultaneously abut against the side wall of the cassette mold 8, and the clamping and fixing of the cassette mold 8 can be realized. The overall operation is simple and convenient; at the same time, in order to prevent the first clamping block 31 from directly contacting the cassette mold 8, a buffer layer 311 is arranged on the side of the first clamping block 31 facing the cassette mold 8. In this embodiment, the buffer layer 311 is preferably set as a flexible rubber pad, and the flexible rubber pad is adhesively fixed on the first clamping block 31.

[0043] Referring to Figure 1 and Figure 4 The glue injection mechanism 4 is used for injecting sealant into the cassette mold 8. The glue injection mechanism 4 is composed of a mounting seat 41, a second driving cylinder 42 and an electric glue injection gun 43. Among them, the mounting seat 41 is slidably arranged on the frame 1, and the sliding direction of the mounting seat 41 is the direction of approaching or departing from the glue injection port 9 on the cassette mold 8. The cylinder block of the second driving cylinder 42 is bolted and fixed to the frame 1, the piston rod of the second driving cylinder 42 is bolted and fixed to the mounting seat 41, the electric glue injection gun 43 is detachably connected to the mounting seat 41, and the glue outlet of the electric glue injection gun 43 is arranged opposite to the glue injection port 9 on the cassette mold 8.

[0044] Referring to Figure 4 and Figure 5, the mounting base 41 is composed of a base 411 and a vertical plate 412. There are two vertical plates 412, and the two vertical plates 412 are oppositely arranged at both ends of the base 411 in the length direction. The vertical plate 412 is integrally formed on the base 411. A clamping groove 413 and a limiting groove 414 are formed in the vertical plate 412 along its own height direction. The clamping groove 413 and the limiting groove 414 are communicated with each other, and the notch size of the limiting groove 414 is smaller than the notch size of the clamping groove 413.

[0045] Refer to Figure 4 and Figure 5 , during use, place the gun body of the electric glue injector 43 between the two vertical plates 412, and then slide it vertically into the clamping groove 413. At this time, the two ends of the electric glue injector 43 can be abutted against the side walls of the clamping groove 413 to form a limit on the electric glue injector 43. At the same time, the inner wall of the limiting groove 414 limits the glue outlet of the electric glue injector 43, so as to ensure the stability of the electric glue injector 43 when the glue outlet of the electric glue injector 43 is inserted into the glue injection port 9 on the cassette mold 8 through the second driving cylinder 42, thereby ensuring the stability of the electric glue injector 43 during the glue injection process.

[0046] Refer to Figure 4 and Figure 5 , during the glue injection process, it is necessary to calculate the internal space size according to the size of the cassette mold 8, so as to calculate the amount of sealant that needs to be injected into the inner cavity of the cassette mold 8, and avoid the situation that the sealant cannot fill the inner cavity of the cassette mold 8 due to too little injected sealant; in addition, by detachably arranging the electric glue injector 43 on the mounting base 41, it is convenient for the staff to disassemble the electric glue injector 43 for cleaning or replacement after the glue injection is completed. Therefore, when it is necessary to test different types of sealants, the electric glue injector 43 is disassembled, cleaned or replaced, so as to ensure the accuracy of the sealant specimen test and make the overall device more convenient to use.

[0047] Refer to Figure 1 and Figure 6 , when the cassette mold 8 is filled with sealant, it is necessary to cure the sealant in the cassette mold 8 for one day first, and then the sealant can be separated from the cassette mold 8 through the gas injection separation mechanism 5; the gas injection separation mechanism 5 is composed of a fixing frame 51 and a blowing gun 52. Among them, the fixing frame 51 is fixed on the frame 1 by bolts. A storage groove 55 is formed at the top of the fixing frame 51. The blowing gun 52 is placed in the storage groove 55. A guide air pipe 53 is arranged at one end of the blowing gun 52 away from the blowing port. One end of the guide air pipe 53 is used to supply air to the blowing gun 52, and the other end of the guide air pipe 53 is communicated with the external air path. A control valve 54 is also installed on the guide air pipe 53.

[0048] Refer to Figure 1 and Figure 6, during use, the staff moves the air blowing gun 52 close to the cartridge mold 8, then inserts the air blowing port on the air blowing gun 52 into the glue injection port 9 on the cartridge mold 8, and then the control valve 54 can be opened to connect the air guide pipe 53, the external air path and the air blowing gun 52, so as to blow air into the inner cavity of the cartridge mold 8 through the air blowing gun 52. Under the action of the air flow, separation is generated between the inner wall of the cartridge mold 8 and the outer side of the sealant specimen. Finally, the cartridge mold 8 can be slowly withdrawn to complete the preparation of the sealant specimen; at the same time, when it is difficult to separate between the inner wall of the cartridge mold 8 and the outer side of the sealant specimen, the cartridge mold 8 can also be directly cut and removed by a cutting device to ensure the flatness, gloss and cleanliness of the outer surface of the sealant specimen.

[0049] The implementation principle of the embodiment of the present application is as follows: during use, the staff fixes the fixing plate 6 on the printing platform of the 3D printer 2, then places the base material 7 into the positioning groove 61 for positioning. Subsequently, the 3D printer 2 directly prints a cartridge mold 8 with a specified size and shape on the base material 7. After printing is completed, the two first driving cylinders 32 are used to synchronously drive the first clamping blocks 31 at the corresponding positions to move until both first clamping blocks 31 abut against the outer wall of the cartridge mold 8, and then the positioning of the cartridge mold 8 can be realized. Subsequently, the second driving cylinder 42 is used to drive the glue outlet of the electric glue injection gun 43 to insert into the glue injection port 9 on the cartridge mold 8, and the sealant is injected into the inner cavity of the cartridge mold 8 through the electric glue injection gun 43. After the inner cavity of the cartridge mold 8 is filled with the sealant, the electric glue injection gun 43 can be withdrawn. At this time, the sealant specimen and the cartridge mold 8 are left on the base material 7. After the sealant in the cartridge mold 8 is cured for one day, the staff inserts the air blowing gun 52 into the glue injection port 9, and then opens the control valve 54 to connect the air blowing gun 52 with the external air path through the air guide pipe 53. Under the action of the air flow, the sealant specimen is separated from the inner wall of the cartridge mold 8. Finally, the cartridge mold 8 can be slowly removed from the base material 7 to complete the preparation of the sealant specimen. The overall process is simpler and more convenient to operate compared with the manual preparation method, and at the same time, the waste of sealant generated during the glue injection process is reduced.

[0050] The difference between this embodiment and Embodiment 1 is that:

[0051] Refer to Figure 7 and Figure 8, the clamping mechanism 3 can also be composed of a second clamping block 33, a sliding sleeve 34, a bidirectional lead screw 35 and a driving motor 36. Among them, there are also two second clamping blocks 33, and the two second clamping blocks 33 are oppositely arranged on both sides of the cassette mold 8. The second clamping block 33 is slidably arranged on the frame 1. The sliding sleeve 34 is arranged corresponding to the second clamping block 33 one by one, and the sliding sleeve 34 is fixed on the second clamping block 33 by bolts. The two sliding sleeves 34 are respectively threadedly connected to one side of the bidirectional lead screw 35. The bidirectional lead screw 35 rotates on the frame 1, and the driving motor 36 is installed on the frame 1. The output shaft of the driving motor 36 is coaxially and fixedly connected to the bidirectional lead screw 35.

[0052] Referring to Figure 7 and Figure 8 , during use, the output shaft of the driving motor 36 rotates to drive the bidirectional lead screw 35 to rotate. The rotation of the bidirectional lead screw 35 drives the two sliding sleeves 34 on both sides to slide synchronously towards each other. The sliding of the sliding sleeve 34 drives the second clamping block 33 to slide towards or away from the cassette mold 8. When the two second clamping blocks 33 are both abutted against the side wall of the cassette mold 8, the clamping and positioning of the cassette mold 8 can be realized.

[0053] Referring to Figure 7 and Figure 8 , in this embodiment, the driving motor 36 can also be replaced by a handwheel; that is, the user rotates the handwheel to drive the bidirectional lead screw 35 to rotate, so as to drive the two second clamping blocks 33 to clamp the cassette mold 8. Compared with using the driving motor 36 to drive the second clamping block 33, it is more convenient for the staff to adjust the moving distance of the second clamping block 33.

[0054] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
