Thus, the exemplary term "below" can include both an orientation above and below.

[0054] In the related art, refrigeration appliances generally use foamed polyurethane or VIP boards (vacuum insulation panels) as the insulation layer. Among them, foamed polyurethane has a relatively low cost but a relatively high thermal conductivity and a relatively low effective space; the processing technology of VIP boards includes processes such as core material / membrane material production, pre-installation, encapsulation, edge wrapping, pasting, assembly, and foaming, and its processing technology is complex and the cost is relatively high.

[0055] In view of this, the present embodiment provides a method for preparing a box body, aiming to simplify the preparation process of the box body, improve the production and processing efficiency of the box body, and reduce costs, thereby solving the above technical problems.

[0056] As Figures 1 to 9 shown, according to an embodiment of the present invention, a method for preparing a box body is proposed. The method for preparing the box body includes:

[0057] Providing a housing 111 and a thermal insulation core 112, coating a first adhesive layer 113 on the inner peripheral wall of the housing 111 and / or the outer peripheral wall of the thermal insulation core 112, and attaching the thermal insulation core 112 to the inner peripheral wall of the housing 111 through the first adhesive layer 113 to assemble the thermal insulation core 112 and the housing 111 into a first pre-assembly 11;

[0058] Provide a box liner 12, and coat a second adhesive layer on the outer peripheral wall of the box liner 12 to form a second pre-assembled component;

[0059] Place the first pre-assembled component 11 and the second pre-assembled component in a preset vacuum environment. In the preset vacuum environment, sleave the first pre-assembled component 11 outside the second pre-assembled component, and make the first pre-assembled component 11 adhere to the outer peripheral wall of the second pre-assembled component through the second adhesive layer to form a box body 1.

[0060] The material of the above-mentioned thermal insulation core material 112 is glass or plastic fiber, which can be used as the support framework of the thermal insulation layer. The outer shell 111 is a U-shaped plate body, and the material of the outer shell 111 is aluminized steel sheet, stainless steel sheet, engineering plastic, etc. The material of the box liner 12 can be ABS (Acrylonitrile Butadiene Styrene), PP (polypropylene), HIPS (High impact polystyrene), etc.

[0061] When preparing the box body 1, apply glue or attach VHB (Very High Bond) tape on the inner peripheral wall of the outer shell 111 or on the outer periphery of the thermal insulation core material 112 or on both the inner peripheral wall of the outer shell 111 and the outer periphery of the thermal insulation core material 112, and attach the thermal insulation core material 112 on the inner peripheral wall of the outer shell 111 to form the first pre-assembled component 11. When attaching the thermal insulation core material 112, it can be attached on the whole surface or locally according to the design. When preparing the first pre-assembled component 11, the preparation of the second pre-assembled component can be carried out simultaneously to improve the preparation efficiency. By applying glue or attaching VHB tape on the outer peripheral wall of the box liner 12, a second pre-assembled component is formed. Then, the prepared first pre-assembled component 11 and the second pre-assembled component are respectively transported to the preset vacuum environment. In the preset vacuum environment, first perform pre-assembly. During pre-assembly, move the first pre-assembled component 11 and the second pre-assembled component closer to each other to a preset distance for positioning, and then perform formal assembly, that is, continue to move the first pre-assembled component 11 and the second pre-assembled component closer to each other until the first pre-assembled component 11 adheres to the outer peripheral wall of the second pre-assembled component through the second adhesive layer.

[0062] Preparation method of the box body 1 of the present invention: First, a first adhesive layer 113 is coated on the outer peripheral wall of the thermal insulation core material 112, or the inner peripheral wall of the outer shell 111, or both on the outer peripheral wall of the thermal insulation core material 112 and the inner peripheral wall of the outer shell 111. The thermal insulation core material 112 is attached to the inner peripheral wall through the first adhesive layer 113 to form a first pre-assembled component 11. At the same time, a second adhesive layer is coated on the outer peripheral wall of the inner container 12 to form a second pre-assembled component. Then, the first pre-assembled component 11 and the second pre-assembled component are both placed in a preset vacuum environment, and the first pre-assembled component 11 is sleeved outside the second pre-assembled component for pre-assembly. Finally, the first pre-assembled component 11 is attached to the outer peripheral wall of the second pre-assembled component through the second adhesive layer to form the box body 1. Through the above preparation method, the processes of separately processing, encapsulating and foaming the vacuum insulation panel are cancelled. The preparation of the first pre-assembled component 11 and the second pre-assembled component can be carried out simultaneously, and then the first pre-assembled component 11 and the second pre-assembled component are assembled to complete the preparation of the box body 1. The preparation process is relatively simple, the production and processing efficiency is relatively high. At the same time, the thermal conductivity coefficient of the thermal insulation layer is low, so that the box body 1 has good heat preservation effect, and the effective space inside the box body 1 is relatively large.

[0063] In some embodiments of the present invention, before the step of sleeving the first pre-assembled component 11 outside the second pre-assembled component and attaching the first pre-assembled component 11 to the outer peripheral wall of the second pre-assembled component through the second adhesive layer, it further includes: providing a pre-embedded positioning member, and coating a sealant on the first connection surface of the pre-embedded positioning member connected to the inner container 12, and / or coating a sealant on the second connection surface of the inner container 12 connected to the pre-embedded positioning member to form a first sealing layer 31. The first sealing layer 31 is used for bonding and sealing the connection between the pre-embedded positioning member and the inner container 12. Specifically, the pre-embedded positioning member includes a positioning clip. When preparing the box body 1, first, an opening 121 is provided on the inner container 12. The side of the fixing clip 20 facing the inner container 12 is the first connection surface, and a sealant is coated on the first connection surface. The sealant can be glue or tape, and the fixing clip 20 is bonded to the outer wall of the inner container 12, or a sealant is coated on the second connection surface of the inner container 12 facing the fixing clip 20 to bond the fixing clip 20 and the inner container 12, or sealants are coated on both the fixing clip 20 and the inner container 12 to bond the fixing clip 20 to the inner container 12.

[0064] In some embodiments of the present invention, after the step of using the first sealing layer 31 to bond and seal the connection between the embedded positioning member and the inner container 12, the following steps are further included: applying a sealant on the outer periphery of the embedded positioning member to form a second sealing layer 41. Specifically, after the fixing clip 20 is installed, a sealant is applied on the outer surfaces of the fixing clip 20 and the first sealing layer 31. The sealant is a heat-curing glue, and a second sealing layer 41 is formed. The second sealing layer 41 can maintain sealing in other areas of the box body 1 that need to be sealed, such as the embedded part interface, the evaporator interface, the wiring harness, and the installation holes of the fixing clip 20. Considering that the second sealing layer 41 is formed inside the box body and it is difficult to irradiate with UV (Ultraviolet) light, a preferred solution is a two-component heat-curing glue with strong initial adhesion. After pre-assembly, the relevant interfaces or holes can be fully bonded and sealed, so that the box body 1 does not leak vacuum during vacuum assembly. When installing the subsequent parts 6, the parts 6 can be placed on the inner wall of the inner container 12, and then the parts 6 are installed by screwing the screws 21 through the openings 121 in the inner container 12 to connect with the fixing clip 20. In other embodiments, the above-mentioned sealant can also be a traditional tape. After the embedded positioning member is installed, the subsequent vacuum assembly of the box body 1 can be carried out.

[0065] In some embodiments of the present invention, the step of sleeving the first pre-assembled part 11 outside the second pre-assembled part includes: evacuating the environment where the first pre-assembled part 11 and the second pre-assembled part are located, so that the first pre-assembled part 11 and the second pre-assembled part are placed in a preset vacuum environment, and driving the first pre-assembled part 11 and the second pre-assembled part to approach each other until the first pre-assembled part 11 is sleeved outside the second pre-assembled part. Specifically, the pre-assembly and formal assembly steps are carried out by a box body processing device 7. The vacuum device includes a chamber 71, a vacuum pumping device 72, an assembly device 73, and a curing device 74. The assembly device 73 includes a first conveying component 731 and a second conveying component 732 that are oppositely arranged. The first conveying component 731 is used to convey the first pre-assembled part 11, and the second conveying component 732 is used to convey the second pre-assembled part. During pre-assembly, the coated outer shell 111 and the inner container 12 are respectively conveyed onto the first conveying component 731 and the second conveying component 732. The first conveying component 731 and the second conveying component 732 drive the outer shell 111 and the inner container 12 to approach each other to a preset distance, and control the preset vacuum environment and the pre-assembly time to complete the pre-assembly.

[0066] In some embodiments of the present invention, the step of attaching the first pre-assembly 11 to the outer peripheral wall of the second pre-assembly through the second adhesive layer includes: in a preset vacuum environment, continuously driving the first pre-assembly 11 and the second pre-assembly closer until the first pre-assembly 11 and the second pre-assembly are mutually attached and bonded. Specifically, when performing the formal assembly, the first transfer assembly 731 and the second transfer assembly 732 continue to drive the outer shell 111 and the inner container 12 closer until they are completely attached, and control the preset vacuum environment and the assembly time to complete the formal assembly.

[0067] In some embodiments of the present invention, in the step of sleeving the first pre-assembly 11 outside the second pre-assembly and attaching the first pre-assembly 11 to the outer peripheral wall of the second pre-assembly through the second adhesive layer, sealant is coated on the third connection surface of the first pre-assembly 11 connected to the second pre-assembly, and / or sealant is coated on the fourth connection surface of the second pre-assembly connected to the first pre-assembly 11 to form a third sealing layer 51. The third sealing layer 51 bonds and seals the connection between the first pre-assembly 11 and the second pre-assembly. During assembly, after the formal assembly is completed, sealant is coated on the third connection surface of the outer shell 111 facing the inner container 12, or on the fourth connection surface of the inner container 12 facing the outer shell 111, or on both the third connection surface and the fourth connection surface. The sealant is UV glue, and the UV glue is cured by UV to seal the connection between the outer shell 111 and the inner container 12, thereby improving the overall sealing performance of the box body 1.

[0068] In some embodiments of the present invention, the method for preparing the box body further includes: after the step of attaching the first pre-assembly 11 to the outer peripheral wall of the second pre-assembly through the second adhesive layer, it further includes: standing and aging and / or post-baking the first adhesive layer 113 and the second adhesive layer to completely cure the glue. The post-baking treatment temperature is 50 - 90 °C, and the time is 10 - 120 min. The specific parameters need to be adjusted according to the glue model and the sealing performance requirements.

[0069] A second aspect of the present invention provides a box body processing device 7. The box body processing device 7 is used to prepare the box body 1 according to the above-mentioned method for preparing the box body. The box body processing device 7 includes a vacuum device. The vacuum device includes a chamber 71, a vacuum pumping device 72, an assembly device 73, and a curing device 74. Among them, the chamber 71 is formed by a closed housing. The housing material is preferably metal, and an observation hole is provided on the housing for process inspection and control. The vacuum pumping device 72 is communicated with the chamber 71. The vacuum pumping device 72 can be arranged inside or outside the chamber 71. The outside of the vacuum pumping device 72 is connected to a vacuum station system to pump the chamber 71 to a preset vacuum value to form a preset vacuum environment. The preset vacuum value can be set according to actual needs.

[0070] The assembling device 73 is arranged inside the chamber 71. The assembling device 73 includes a first conveying component 731 and a second conveying component 732 which are arranged oppositely. The first conveying component 731 includes a first conveying machine table. The first conveying machine table is connected to a servo motor and can control the position and distance of the first conveying machine table according to parameter settings. A first fixing member 7311 is arranged on the first conveying machine table. The first fixing member 7311 is used to fix the first pre-assembled part 11, facilitating assembling positioning and control. The second pre-assembled part conveys the second pre-assembled part to make the first pre-assembled part 11 and the second pre-assembled part approach each other. The second conveying component 732 includes a second conveying machine table. The second conveying machine table is connected to a servo motor and can control the position and distance of the second conveying machine table according to parameter settings. A second fixing member 7321 is arranged on the second conveying machine table. The second fixing member 7321 is used to fix the second pre-assembled part, facilitating assembling positioning and control.

[0071] The vacuum device of this embodiment further includes a control device and a positioning device. The first conveying component 731 and the second conveying component 732 are controlled and coordinated by the control device to complete the assembling process. The relative positions of the first conveying component 731 and the second conveying component 732 can be up and down, left and right, inclined, etc., to cooperate with different application scenarios. The first conveying component 731 and the second conveying component 732 can be used for the assembly of the refrigerator outer shell 111 and the liner 12, the assembly of the thermal insulation film bag and the core material, the assembly of the vacuum fresh-keeping drawer shell and the drawer, etc. The positioning device can be positioned jointly through a mold or can be positioned by grasping through a CCD (charge-coupled device) for positioning during assembling.

[0072] The curing device 74 is arranged inside the chamber 71 and is used for curing the first bonding layer 113 and the second bonding layer. The curing device 74 includes a curing component 741 and a first transmission device arranged on the curing component 741. Usually, the curing component 741 can be hidden inside the housing through the first transmission device and extended to the product surface during the curing process stage to quickly cure the glue. The curing component 741 can be a UV lamp, an infrared heating tube, a pressing and heat-sealing strip, a blowing device, etc.

[0073] In this embodiment, the vacuum device further includes a glue coating device 75. The glue coating device 75 is arranged inside the chamber 71. The glue coating device 75 is preferably of the inkjet type. The rear end of the glue coating device 75 is connected to a glue storage tank with positive and negative pressure conditions, which is used for coating the thermal insulation core material 112 and the liner 12 before assembly, and for performing the glue coating process at the connection between the liner 12 and the outer shell 111 after assembly.

[0074] In other embodiments, the vacuum device may further be provided with an auxiliary device, which includes an auxiliary component and a second transmission device disposed on the auxiliary component. The auxiliary component may be a cleaning device or a component for performing other auxiliary processes. Usually, the auxiliary component can be hidden inside the housing through the second transmission device and extended during the auxiliary process stage.

[0075] A third aspect of the present invention provides a box body 1, which is processed by the above-mentioned box body processing equipment 7. When assembling the box body 1 using the vacuum device, a manipulator or other conveying device conveys the glued outer shell 111 and the inner tank 12 to the first conveyor platform and the second conveyor platform of the vacuum device respectively, and then the first conveyor platform and the second conveyor platform slowly approach the outer shell 111 and the inner tank 12 according to the parameter settings. At the same time, the vacuum pumping device 72 starts to pump vacuum. This stage is pre-assembly, and the vacuum degree is 10 - 500 Pa. The distance between the outer shell 111 and the inner tank 12 is controlled within 1 - 5 mm through the positioning device, and the pre-assembly time is controlled within 3 - 30 s. After pre-assembly, formal assembly is carried out. The outer shell 111 and the inner tank 12 get closer until they are completely fitted. At the same time, the vacuum degree further decreases and finally reaches 0.1 - 2 Pa. The assembly time is 1 - 15 s to complete the assembly. After the assembly is completed, the vacuum degree needs to be maintained further so that the internal air is completely exhausted, and the time is 1 - 10 s. Meanwhile, the curing component 741 starts UV curing, with an energy of 500 - 2000 mJ / m 2 ·s, and the curing time is 5 - 60 s. During the curing process, the vacuum degree is gradually released and finally reaches the same air pressure as the outside. During the assembly process, when switching and controlling the vacuum degree, it is necessary to adjust and optimize the parameters in combination with the heat preservation requirements and material properties of the corresponding product to prevent defects such as local deformation or insufficient exhaust caused by too fast vacuum switching. After curing is completed, the entire box body 1 is left to stand for aging or transferred to a post-baking heating oven for post-baking treatment. After the post-baking is completed, the vacuum insulation layer of the box body 1 is prepared, and the box body 1 can be put into the subsequent assembly process.

[0076] A fourth aspect of the present invention provides a refrigeration device.
