Description

Technical Field

[0001] This application relates to the field of glue dispensing technology, specifically to a glue dispensing mold. Background Technology

[0002] With the rapid development of the electronics industry, integration is becoming increasingly dense. Currently, for precision low-pressure injection molding processes such as LSR (liquid silicone injection molding technology), liquid silicone is typically injected into a potting mold to be molded together with the metal components of the mobile phone.

[0003] However, the aforementioned potting molds are currently only suitable for injecting one type of material. For structures with high performance requirements, such as flexible screens and curved screens, they cannot simultaneously meet the requirements of product protection and dimensional stability. Therefore, a two-stage potting process needs to be developed to meet production requirements. When potting a product twice, two sets of potting molds are typically used to pot the product separately. However, using two sets of potting molds to pot the product separately requires two positioning operations and two mold changes, which will generate a large cumulative tolerance, resulting in lower product accuracy. In more serious cases, when assembling the mold, positional misalignment may prevent assembly from being completed. In addition, the aforementioned potting molds require replacing the entire potting mold set, which adds an extra mold disassembly and positioning operation, resulting in low potting efficiency. Summary of the Invention

[0004] In view of the above, it is necessary to propose a dispensing mold to improve the accuracy and dispensing efficiency of dispensing products.

[0005] One embodiment of this application provides a potting mold, including a male mold, a first female mold, and a second female mold. The first female mold and the second female mold are respectively adapted to be molded with the male mold along the mold-closing direction. The male mold includes a male mold base plate, a positioning component, and a floating component. The positioning component is disposed on the male mold base plate and is used to position the product. The floating component is floatingly disposed on the male mold base plate along the mold-closing direction. The first female mold includes a first female mold cover plate and a first light-transmitting molding component. The first light-transmitting molding component is disposed on the first female mold cover plate. When the first female mold and the male mold are molded together, the first light-transmitting molding component, the floating component, and the product surround... The first molding cavity is formed by combining the two molds. The first molding cavity is used to form a first adhesive layer on the surface of the product. The second mold includes a second mold cover plate, a second light-transmitting molding component and a pressing member. The second light-transmitting molding component is disposed on the second mold cover plate and the pressing member is disposed on the second mold cover plate and located on one side of the second light-transmitting molding component. When the second mold and the male mold are closed, the pressing member pushes the floating component towards the male mold base plate to allow the second light-transmitting molding component, the floating component and the product to surround and form a second molding cavity. The second molding cavity is used to form a second adhesive layer covering the first adhesive layer.

[0006] In some embodiments, the floating component includes a floating member, an elastic member, and an extrusion member.

When the second female mold and the male mold are closed, the floating member is used to drive the extrusion member towards the male mold base plate under the pushing action of the pressing member, so that an encapsulation gap is formed between the first adhesive layer and the extrusion member. The encapsulation gap is part of the second molding cavity.

[0007] In some embodiments, the floating member has abutment protrusions on both sides, and there are two abutment members. The two abutment members are located on opposite sides of the second light-transmitting molding component.

[0009] In some embodiments, the wall of the receiving hole is provided with a plurality of spaced connecting protrusions, and the extruder covers the plurality of connecting protrusions.

[0010] In some embodiments, there are two of each of the first extrusion portion and the second extrusion portion. The two first extrusion portions are symmetrically arranged around the receiving hole, and the two second extrusion portions are respectively connected to the two first extrusion portions. The two second extrusion portions extend into the receiving hole and abut against the two side walls of the positioning component.

[0012] In some embodiments, the extruder has a pressing slope on the side facing the flexible member, and the flexible member has an abutting slope that abuts against the pressing slope, the pressing slope and the abutting slope being arranged parallel to each other.

[0013] In some embodiments, the angle between the pressing slope and the mold closing direction ranges from 1.5 degrees to 3 degrees.

[0014] In some embodiments, the floating component has a positioning hole, and the first female mold further includes a positioning component, which is disposed on the cover plate of the first female mold. The positioning component is used to insert and position itself with the positioning hole when the first female mold and the male mold are closed.

[0015] In some embodiments, the potting mold further includes a first sealing adhesive and a second sealing adhesive; the first sealing adhesive is disposed at the connection position between the first light-transmitting molding component and the floating component to restrict the glue injected in the first molding cavity from overflowing from the gap between the first light-transmitting molding component and the floating component; the second sealing adhesive is disposed at the connection position between the second light-transmitting molding component and the floating component to restrict the glue injected in the second molding cavity from overflowing from the gap between the second light-transmitting molding component and the floating component.

[0016] In some embodiments, the first light-transmitting molding component has a first molding groove and a first adhesive coating groove, the first molding groove, the floating component, and the product surround to form the first molding cavity, the first adhesive coating groove is disposed around the first molding groove and communicates with the side wall of the first light-transmitting molding component facing the male mold, and the first sealing adhesive is disposed in the first adhesive coating groove; and / or, the second light-transmitting molding component has a second molding groove and a second adhesive coating groove, the second molding groove, the floating component, and the product surround to form the second molding cavity, the second adhesive coating groove is disposed around the second molding groove and communicates with the side wall of the second light-transmitting molding component facing the male mold, and the second sealing adhesive is disposed in the second adhesive coating groove.

[0017] In this embodiment of the application, when the glue-filling mold is used to fill the product, the product is positioned on the positioning component.

The second light-transmitting molding component, the floating component, and the product enclose to form a second molding cavity. Glue is poured into the second molding cavity. After the glue cures, a second glue layer covering the first glue layer is formed on the surface of the first glue layer. Since a single set of male molds is used for two glue-filling operations, the product does not need to be repositioned, thereby reducing positioning errors and improving the accuracy of the glue-filled product. In addition, since the male mold does not need to be changed, the efficiency of the glue-filled product is improved. Attached Figure Description

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0031] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0032] Please see Figure 1 , Figure 2 and Figure 5 This application provides a potting mold 100 for potting a product 600. The product 600 can be a flexible screen, a 3D curved glass screen, a circuit board, etc. For ease of understanding, this application uses the example of a flexible screen as the product 600 and the potting mold 100 potting the four sides of the product 600. Obviously, this is not a limitation of this application.

[0033] Please see Figures 1 to 7 The potting mold 100 includes a male mold 10, a first female mold 20, and a second female mold 30. The first female mold 20 and the second female mold 30 are respectively along... Figure 1 and Figure 2 The mold closing direction F shown is compatible with the mold closing direction of the male mold 10.

[0034] The male mold 10 includes a male mold base plate 11, a positioning component 12, and a floating component 13. The positioning component 12 is located on the male mold base plate 11 and is used to position the product 600. The floating component 13 is floating on the male mold base plate 11 along the mold closing direction F.

[0035] The first female mold 20 includes a first female mold cover plate 21 and a first light-transmitting molding component 22. The first light-transmitting molding component 22 is disposed on the first female mold cover plate 21. When the first female mold 20 and the male mold 10 are closed, the first light-transmitting molding component 22, the floating component 13, and the product 600 surround and form a first molding cavity 15 (see [link]). Figure 8 The first molding cavity 15 is used to form the first adhesive layer 610 on the surface of the product 600.

[0036] The second female mold 30 includes a second female mold cover plate 31, a second light-transmitting forming component 32, and a pressing member 33. The second light-transmitting forming component 32 is disposed on the second female mold cover plate 31, and the pressing member 33 is disposed on the second female mold cover plate 31 and located on one side of the second light-transmitting forming component 32. When the second female mold 30 and the male mold 10 are closed, the pressing member 33 pushes the floating component 13 toward the male mold base plate 11, and the second light-transmitting forming component 32, the floating component 13, and the product 600 enclose to form the second forming cavity 16 (see [link]). Figure 9 The second molding cavity 16 is used to mold the second adhesive layer 620 that covers the first adhesive layer 610.

[0037] When the product 600 is potted with glue using the potting mold 100, the product 600 is positioned on the positioning component 12. The first female mold 20 and the male mold 10 are closed along the mold closing direction F. The first light-transmitting molding component 22, the floating component 13, and the product 600 form a first molding cavity 15. Glue is poured into the first molding cavity 15. After the glue cures, a first adhesive layer 610 is formed on the surface of the product 600. After the first female mold 20 and the male mold 10 are opened, the second female mold 30 and the male mold 10 are closed along the mold closing direction F. The pressing component 33 pushes the floating component 13 to move toward the male mold base plate 11. The second light-transmitting molding component 32, the floating component 13, and the product 600 form a second molding cavity 16. Glue is poured into the second molding cavity 16. After the glue cures, a second adhesive layer 620 is formed on the surface of the first adhesive layer 610, covering the first adhesive layer 610. Since a single mold 10 is used for two potting operations on product 600, product 600 does not need to be repositioned, thereby reducing cumulative tolerances and improving the accuracy of potting product 600. Furthermore, since the mold 10 does not need to be changed, the efficiency of potting product 600 is improved.

[0038] Please see Figure 3 , Figure 5 and Figure 7 In some embodiments, the positioning component 12 includes a fixing member 121 and an adsorption member 122. The fixing member 121 is disposed on the mold base plate 11, and the adsorption member 122 is disposed on the fixing member 121. The adsorption member 122 is used to adsorb and position the product 600. Specifically, the adsorption member 122 can be a vacuum nozzle. By setting a vacuum nozzle to adsorb and position the product 600, the probability of scratching the product 600 is reduced, and the stability of the positioned product 600 is improved.

[0039] Please refer to the following: Figure 8 and Figure 9In some embodiments, the floating component 13 includes a floating member 131, an elastic member 132, and an extruding member 133. The floating member 131 is spaced apart from the male mold base plate 11 along the mold closing direction F. The floating member 131 has a receiving hole 1311. The fixing member 121 of the positioning component 12 is fixed to the male mold base plate 11 and passes through the receiving hole 1311, so that the positioning component 12 is installed in the receiving hole 1311. The elastic member 132 is disposed between the floating member 131 and the male mold base plate 11, and the two ends of the elastic member 132 are respectively connected to the floating member 131 and the male mold base plate 11. The extrusion member 133 is disposed on the wall of the receiving hole 1311. The extrusion member 133 is used to abut against the first light-transmitting molding component 22 or the second light-transmitting molding component 32 to form the first molding cavity 15 or the second molding cavity 16. When the second female mold 30 and the male mold 10 are closed, the floating member 131 is used to drive the extrusion member 133 towards the male mold base plate 11 under the pushing action of the pressing member 33, so that the first adhesive layer 610 and the extrusion member 133 form a wrapping gap 161, which is part of the second molding cavity 16.

[0040] By setting up a floating component 131, an elastic component 132, and an extrusion component 133, when the first female mold 20 and the male mold 10 are closed, the elastic component 132 elastically supports the floating component 131, and the floating component 131 drives the extrusion component 133 to elastically abut against the first light-transmitting molding component 22, thereby reducing the impact of mold closing error on the accuracy of forming the first molding cavity 15, and thus improving the accuracy of forming the first molding cavity 15; when the second female mold 30 and the male mold 10 are closed, the elastic component 132 elastically supports the floating component 131, and the floating component 131 drives the extrusion component 133 to elastically abut against the second light-transmitting molding component 32. Under the pushing action of the pressing component 33, the floating component 131 drives the extrusion component 133 to move towards the male mold base plate 11, thereby separating the extrusion component 133 from the first adhesive layer 610 and forming a wrapping gap 161 between the first adhesive layer 610 and the extrusion component 133, realizing the function of forming the second cavity 16 without replacing the male mold 10.

[0041] In some embodiments, the elastic element 132 may be a spring, a sheet, or the like.

[0042] In some embodiments, the bottom surface of the floating member 131 facing the male mold base plate 11 and the top surface of the male mold base plate 11 facing the floating member 131 are both provided with assembly grooves 113, and the two ends of the elastic member 132 are respectively inserted into the two oppositely arranged assembly grooves 113, thereby improving the stability of the floating member 131 floating driven by the elastic member 132.

[0043] Please see Figure 3 , Figure 5 , Figure 6 and Figure 7In some embodiments, the floating member 131 has abutment protrusions 1312 on both sides, and there are two pressing members 33, which are located on opposite sides of the second light-transmitting molding assembly 32. When the second female mold 30 and the male mold 10 are closed, the two pressing members 33 push against the two abutment protrusions 1312 respectively, thereby improving the accuracy and stability of the pressing members 33 pushing the floating member 131 toward the male mold base plate 11, which in turn helps to form the wrapping gap 161 and the second cavity 16 accurately.

[0044] In some embodiments, the extruder 133 is made of a high-transmittance polymer material, which facilitates the use of curing light to irradiate from one side of the mold 10. The curing light can penetrate the extruder 133 and irradiate the adhesive for curing. Furthermore, the extruder 133 elastically abuts against the fixing member 121, reducing the probability of adhesive injected in the first molding cavity 15 overflowing from the gap between the first translucent molding component 22 and the extruder 133, and the probability of adhesive injected in the second molding cavity 16 overflowing from the gap between the second translucent molding component 32 and the extruder 133. Additionally, because the extruder 133, made of a high-transmittance polymer material, has high release and low shrinkage properties, even if the extruder 133 is connected to the adhesive injected into the second molding cavity 16, demolding is not affected, and the dimensions are stable, thereby improving the accuracy of the dispensing mold 100 in dispensing adhesive onto the product 600.

[0045] In some embodiments, the extrusion part 133 is made of chlorinated polyolefin resin. The light transmittance of the extrusion part made of chlorinated polyolefin resin is >90%, the demolding force is <2KGf, and the shrinkage rate is <1%. This facilitates the use of curing light to cure the adhesive at the connection between the extrusion part 133 and the first light-transmitting molding component 22, as well as the adhesive at the connection between the extrusion part 133 and the second light-transmitting molding component 32. This reduces the probability of the adhesive injected in the first molding cavity 15 overflowing from the gap between the first light-transmitting molding component 22 and the extrusion part 133, and the probability of the adhesive injected in the second molding cavity 16 overflowing from the gap between the second light-transmitting molding component 32 and the extrusion part 133. Furthermore, the dimensions of the extrusion part 133 are stable, which facilitates demolding and improves the accuracy of the glue potting mold 100 in potting the product 600.

[0046] Please see Figure 5 , Figure 7 , Figure 8 and Figure 9In some embodiments, the mold base plate 11 has a light-transmitting hole 111, which communicates with the receiving hole 1311. By providing the light-transmitting hole 111, the curing light can pass through the light-transmitting hole 111, the receiving hole 1311, and the extruder 133 to enter the first molding cavity 15 and the second molding cavity 16 respectively. This facilitates the curing of the adhesive at the connection between the extruder 133 and the first light-transmitting molding component 22, as well as the adhesive at the connection between the extruder 133 and the second light-transmitting molding component 32. This reduces the probability of the adhesive injected in the first molding cavity 15 overflowing from the gap between the first light-transmitting molding component 22 and the extruder 133, and the probability of the adhesive injected in the second molding cavity 16 overflowing from the gap between the second light-transmitting molding component 32 and the extruder 133.

[0047] In some embodiments, the extruder 133 includes a first extrusion portion 1331 and a second extrusion portion 1332. The first extrusion portion 1331 is disposed on the floating member 131 and located at the receiving hole 1311. The first extrusion portion 1331 is used to abut against the first light-transmitting molding component 22 or the second light-transmitting molding component 32 to form a first molding cavity 15 or a second molding cavity 16. The second extrusion portion 1332 is connected to the first extrusion portion 1331 and extends into the receiving hole 1311. The second extrusion portion 1332 abuts against the positioning component 12.

[0048] By providing the first extrusion part 1331, when the first female mold 20 and the male mold 10 are closed, the first extrusion part 1331, together with the first light-transmitting molding component 22 and the product 600, forms the first molding cavity 15. When the second female mold 30 and the male mold 10 are closed, the first extrusion part 1331, together with the second light-transmitting molding component 32 and the product 600, forms the first molding cavity 15, thereby improving the accuracy of forming the first molding cavity 15 and the second molding cavity 16. By providing the second extrusion part 1332 to abut against the positioning component 12, the probability of glue overflowing from the receiving hole 1311 in the first molding cavity 15 and the second molding cavity 16 is reduced.

[0049] In some embodiments, the wall of the receiving hole 1311 is provided with a plurality of spaced connecting protrusions 1311a. Specifically, in this embodiment, a plurality of spaced connecting protrusions 1311a are provided on the inner side of the wall of the receiving hole 1311, and the extruder 133 covers the plurality of connecting protrusions 1311a. By providing the connecting protrusions 1311a, the contact area between the extruder 133 and the floating member 131 is increased, thereby improving the firmness of the connection between the extruder 133 and the floating member 131.

[0050] In some embodiments, there are two extrusion members 133, which are symmetrically arranged on the wall of the receiving hole 1311 with the receiving hole 1311 as the center. Specifically, two first extrusion parts 1331 are symmetrically arranged on the top and inner side of the wall of the receiving hole 1311 with the receiving hole 1311 as the center, and two second extrusion parts 1332 are respectively connected to the two first extrusion parts 1331, and the two second extrusion parts 1332 extend into the receiving hole 1311 and abut against the two side walls of the fixing member 121 of the positioning assembly 12. The plurality of connecting protrusions 1311a are divided into two groups, and the two groups of connecting protrusions 1311a are respectively provided on the inner side of the two oppositely arranged hole walls of the receiving hole 1311, and the two extrusion members 133 respectively cover the two groups of connecting protrusions 1311a.

[0051] By setting the number of extruders 133 to two, the accuracy of forming the first molding cavity 15 and the second molding cavity 16 is improved, and the probability of glue overflowing from the receiving hole 1311 in the first molding cavity 15 and the second molding cavity 16 is further reduced.

[0052] In some other embodiments, the number of extruders 133 may also be one. Extruder 133 includes two first extrusion parts 1331 and two second extrusion parts 1332. The two first extrusion parts 1331 are symmetrically arranged on the top and inner side of the hole wall of the receiving hole 1311 with the receiving hole 1311 as the center. The two second extrusion parts 1332 are respectively connected to the two first extrusion parts 1331. The two second extrusion parts 1332 extend into the receiving hole 1311 and abut against the two side walls of the fixing member 121 of the positioning assembly 12.

[0053] Please refer to it again. Figure 5 , Figure 7 , Figure 8 and Figure 9 In some embodiments, the male mold 10 further includes a flexible member 14, which is sleeved on the fixing member 121 and abuts against the extrusion member 133.

[0054] By setting the flexible part 14 to abut against the extruder 133, the flexible part 14 can effectively seal the gap between the flexible part 14 and the extruder 133 when it deforms under the extrusion action of the extruder 133, thereby reducing the probability of the glue in the first molding cavity 15 and the second molding cavity 16 overflowing from the gap between the flexible part 14 and the extruder 133.

[0055] In some embodiments, the flexible member 14 is made of liquid silicone rubber (LSR), which has a Shore hardness of 50-60A, light transmittance >90%, and demolding force <2KGf. The flexible member 14 is sleeved on the fixing member 121 of the positioning assembly 12 and abuts against the second extrusion part 1332, thereby reducing the probability of adhesive overflowing from the receiving hole 1311 in the first molding cavity 15 and the second molding cavity 16, and facilitating the curing of adhesive in the first molding cavity 15 and the second molding cavity 16 using curing light.

[0056] In some embodiments, the extruder 133 has a pressing slope 1332a on the side facing the flexible member 14, the pressing slope 1332a is disposed on the second extrusion part 1332, and the flexible member 14 has an abutting slope 141 that abuts against the pressing slope 1332a, the pressing slope 1332a and the abutting slope 141 are disposed parallel to each other.

[0057] When the first female mold 20 and the male mold 10 are closed, the pressing inclined surface 1332a and the abutting inclined surface 141 adhere to each other to maintain a seal, thereby reducing the probability of glue overflowing from the receiving hole 1311 in the first molding cavity 15. When the second female mold 30 and the male mold 10 are closed, the floating component 13 moves towards the male mold base plate 11 under the pushing action of the pressing component 33. The extrusion component 133 separates from the first adhesive layer 610 and forms a wrapping gap 161 between the first adhesive layer 610 and the extrusion component 133. The pressing inclined surface 1332a presses against the abutting inclined surface 141 and adheres tightly to the abutting inclined surface 141, thereby reducing the probability of glue overflowing from the receiving hole 1311 in the second molding cavity 16.

[0058] In some embodiments, the angle between the pressing inclined surface 1332a and the mold closing direction F ranges from 1.5 degrees to 3 degrees. This setting can improve the sealing effect between the pressing inclined surface 1332a and the abutting inclined surface 141, and reduce the probability of the floating component 13 crushing the flexible component 14.

[0059] In some embodiments, the angle between the pressing inclined surface 1332a and the mold closing direction F can be 1.5 degrees, 2 degrees, 2.5 degrees and 3 degrees.

Figure 3 , Figure 4 , Figure 5 and Figure 8In some embodiments, the first light-transmitting molding assembly 22 includes a first light-transmitting element 221 and a first molding element 222. The first molding element 222 is made of a light-transmitting flexible material. The first light-transmitting element 221 is disposed on the first female mold cover plate 21, and the first molding element 222 is disposed on the side of the first light-transmitting element 221 opposite to the first female mold cover plate 21. When the first female mold 20 and the male mold 10 are closed, the first molding element 222, the floating assembly 13, and the product 600 surround and form the first molding cavity 15. Since the first molding element 222 is made of a light-transmitting flexible material, the probability of the first light-transmitting molding assembly 22 damaging the product 600 due to dimensional tolerances is reduced. In addition, since both the first light-transmitting element 221 and the first molding element 222 are light-transmitting, it is convenient to use curing light to cure the adhesive in the first molding cavity 15, thereby improving the efficiency of the potting mold 100 in potting the product 600.

[0061] In some embodiments, the first light-transmitting element 221 is made of glass, which improves the efficiency of curing the adhesive in the first molding cavity 15 using curing light due to the high light transmittance of glass.

[0062] In some embodiments, the first molded part 222 is made of liquid silicone rubber with a hardness of Shore 50-60A, light transmittance >90%, and demolding force <2KGf, thereby reducing the probability of crushing the product 600, improving the efficiency of curing the adhesive in the first molding cavity 15 using curing light, and facilitating the rapid demolding of the first light-transmitting molding component 22.

[0063] In some embodiments, the first master mold cover plate 21 has a first light-transmitting hole 211, which corresponds to the first light-transmitting element 221. By providing the first light-transmitting hole 211, curing light can pass through the first light-transmitting hole 211, the first light-transmitting element 221, and the first molding element 222 and enter the first molding cavity 15, thereby improving the efficiency of curing the adhesive in the first molding cavity 15 using curing light.

[0064] In some embodiments, the first mold 20 further includes a first injection nozzle 23, which is inserted into the first mold cover plate 21, the first light-transmitting element 221 and the first molding element 222 and extends into the first molding cavity 15, thereby facilitating the injection of glue into the first molding cavity 15.

[0065] In some embodiments, the floating member 131 has a positioning hole 1313, and the first female mold 20 also includes a positioning member 24, which is disposed on the first female mold cover plate 21. The positioning member 24 is used to insert and position itself with the positioning hole 1313 when the first female mold 20 and the male mold 10 are closed. By providing the positioning hole 1313 and the positioning member 24, the accuracy of the contact between the first forming member 222 and the extrusion member 133 is improved, thereby improving the accuracy of forming the first forming cavity 15.

[0066] In some embodiments, the male mold base plate 11 has a limiting hole 112, and the first female mold 20 also includes a first limiting member 25. When the first female mold 20 and the male mold 10 are closed, the first limiting member 25 is inserted and positioned with the limiting hole 112, thereby improving the accuracy of the first female mold 20 and the male mold 10 closing.

[0067] Please see Figure 3 , Figure 6 , Figure 7 and Figure 9 In some embodiments, the second light-transmitting molding assembly 32 includes a second light-transmitting element 321 and a second molding element 322. The second molding element 322 is made of a light-transmitting flexible material. The second light-transmitting element 321 is disposed on the second female mold cover plate 31, and the second molding element 322 is disposed on the side of the second light-transmitting element 321 opposite to the second female mold cover plate 31. When the second female mold 30 and the male mold 10 are closed, the second molding element 322, the floating assembly 13, and the product 600 surround and form the second molding cavity 16. Since the second molding element 322 is made of a light-transmitting flexible material, the probability of the second light-transmitting molding assembly 32 damaging the product 600 due to dimensional tolerances is reduced. In addition, since both the second light-transmitting element 321 and the second molding element 322 are light-transmitting, it is convenient to use curing light to cure the adhesive in the second molding cavity 16, thereby improving the efficiency of the potting mold 100 in potting the product 600.

[0068] In some embodiments, the second light-transmitting element 321 is made of glass, which improves the efficiency of curing the adhesive in the second molding cavity 16 using curing light due to the high light transmittance of glass.

[0069] In some embodiments, the second molding component 322 is made of liquid silicone rubber with a Shore hardness of 50-60A, light transmittance >90%, and demolding force <2KGf, thereby reducing the probability of crushing the product 600, improving the efficiency of curing the adhesive in the second molding cavity 16 using curing light, and facilitating the rapid demolding of the second light-transmitting molding component 32.

[0070] In some embodiments, the second master mold cover plate 31 has a second light-transmitting hole 311, which corresponds to the second light-transmitting element 321. By providing the second light-transmitting hole 311, curing light can pass through the second light-transmitting hole 311, the second light-transmitting element 321, and the second molding element 322 and enter the second molding cavity 16, thereby improving the efficiency of curing the adhesive in the second molding cavity 16 using curing light.

[0071] In some embodiments, the second mold 30 further includes a second injection nozzle 34, which is inserted into the second mold cover plate 31, the second light-transmitting element 321 and the second molding element 322 and extends into the second molding cavity 16, thereby facilitating the injection of glue into the second molding cavity 16.

[0072] The second female mold 30 also includes a second limiting member 35. When the second female mold 30 and the male mold 10 are closed, the second limiting member 35 is inserted into the limiting hole 112 for positioning, thereby improving the accuracy of the second female mold 30 and the male mold 10 closing.

[0073] In some embodiments, the first mold cover plate 21 and the second mold cover plate 31 are both made of metal material, thereby improving the structural strength of the first mold 20 and the second mold 30.

[0074] Please refer to it again. Figure 8 and Figure 9 In some embodiments, the glue potting mold 100 further includes a first sealing glue 40, which is disposed at the connection position between the first molding part 222 of the first light-transmitting molding component 22 and the extrusion part 133 of the floating component 13, so as to restrict the glue injected in the first molding cavity 15 from overflowing from the gap between the first light-transmitting molding component 22 and the floating component 13.

[0075] Because product 600 has tolerances during production, the first female mold 20 and male mold 10 cannot form a stable pre-compression on product 600 when they are closed. As a result, the glue injected into the first molding cavity 15 is prone to overflow from the gap between the first light-transmitting molding component 22 and the floating component 13. By setting the first sealing glue 40 to seal the gap between the first light-transmitting molding component 22 and the floating component 13, the probability of the glue injected into the first molding cavity 15 overflowing from the gap between the first light-transmitting molding component 22 and the floating component 13 is reduced.

[0076] In some embodiments, the potting mold 100 further includes a second sealing adhesive 50, which is disposed at the connection position between the second molding member 322 of the second light-transmitting molding assembly 32 and the extrusion member 133 of the floating assembly 13, so as to restrict the glue injected in the second molding cavity 16 from overflowing from the gap between the second light-transmitting molding assembly 32 and the floating assembly 13.

[0077] Because product 600 has tolerances during production, the second female mold 30 and male mold 10 cannot form a stable pre-compression on product 600 when they are closed. As a result, the glue injected into the second molding cavity 16 is prone to overflow from the gap between the second light-transmitting molding component 32 and the floating component 13. By setting the second sealing glue 50 to seal the gap between the second light-transmitting molding component 32 and the floating component 13, the probability of the glue injected into the second molding cavity 16 overflowing from the gap between the second light-transmitting molding component 32 and the floating component 13 is reduced.

[0078] In some embodiments, the first molding part 222 of the first light-transmitting molding component 22 has a first molding groove 2221 and a first adhesive coating groove 2222. The first molding groove 2221, the floating component 13 and the product 600 surround to form a first molding cavity 15. The first adhesive coating groove 2222 is arranged around the first molding groove 2221 and communicates with the side wall of the first molding part 222 of the first light-transmitting molding component 222 facing the male mold 10. The first sealing colloid 40 is disposed in the first adhesive coating groove 2222.

[0079] By providing the first molding groove 2221, it is easier to form the first molding cavity 15 by surrounding the floating component 13 and the product 600. By providing the first adhesive application groove 2222, the accuracy of applying the first sealing adhesive 40 is improved.

[0080] In some embodiments, the second molding part 322 of the second light-transmitting molding component 32 has a second molding groove 3221 and a second adhesive coating groove 3222. The second molding groove 3221, the floating component 13 and the product 600 surround to form a second molding cavity 16. The second adhesive coating groove 3222 is disposed around the second molding groove 3221 and communicates with the side wall of the second molding part 322 of the second light-transmitting molding component 322 facing the male mold 10. The second sealing colloid 50 is disposed in the second adhesive coating groove 3222.

[0081] By providing the second molding groove 3221, it is easier to form the second molding cavity 16 by surrounding the floating component 13 and the product 600. By providing the second adhesive application groove 3222, the accuracy of applying the second sealing adhesive 50 is improved.

[0082] In some embodiments, when the first female mold 20 and the male mold 10 are closed, a robotic arm (not shown) drives a glue gun (not shown) to apply glue to the first glue application tank 2222 to form the first sealing colloid 40; when the second female mold 30 and the male mold 10 are closed, the robotic arm drives a glue gun to apply glue to the second glue application tank 3222 to form the second sealing colloid 50.

[0083] Understandably, when the first female mold 20 and the male mold 10 are opened, the first sealing compound 40 needs to be peeled off so that the first female mold 20 can be reused. When the second female mold 30 and the male mold 10 are opened, the second sealing compound 50 needs to be peeled off so that the second female mold 30 can be reused.

[0084] In summary, by using a single mold 10 for two gluing operations on the product 600 using the gluing mold 100 in this embodiment, the product 600 does not need to be repositioned, thereby reducing positioning errors and improving the accuracy of gluing the product 600. Furthermore, since it is not necessary to change the mold 10, the efficiency of gluing the product 600 is improved.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
