[0041] The present invention provides a hot pressing device for smart glasses. The smart glasses include a frame and two temple arms 200 rotatably mounted at opposite ends of the frame. The temple arms 200 include an outer shell 210 and an inner shell 220 that are spliced together, and the smart glasses are configured as AR glasses, VR glasses, etc.

[0042] In the embodiments of the present invention, as Figures 1 to 10 shown, the hot pressing device includes a preheating module 110 and a heating and fixing module 140. The preheating module 110 includes a fixing fixture 120 and a preheating device 130. The outer shell 210 and / or the inner shell 220 are fixed to the fixing fixture 120 to provide a place for the hot pressing adhesive film to be placed at the splicing joint of the outer shell 210 and / or the inner shell 220. The preheating device 130 is used to press and heat the hot pressing adhesive film to fix the hot pressing adhesive film at the splicing joint of the outer shell 210 and / or the inner shell 220. The heating and fixing module 140 includes a pressing fixture 150 and a heating device 160. The pressing fixture 150 is used to splice and press the inner shell 220 and the outer shell 210 so that the hot pressing adhesive film is clamped at the splicing joint of the inner shell 220 and the outer shell 210. The heating device 160 is used to heat the pressing fixture 150 to bond and fix the inner shell 220 and the outer shell 210.

[0043] Specifically, referring to Figure 1, the temple 200 is often configured as a spatially curved structure to improve the wearing comfort. The splicing surface of the inner shell 220 and the outer shell 210 is also often a spatial curved surface. And in order to pursue light weight, the thicknesses of the inner shell 220 and the outer shell 210 are small. If glue is directly coated on the periphery of the splicing part of the inner shell 220 and / or the outer shell 210, on the one hand, the glue is liquid and it is difficult to control the amount of glue, and glue overflow or incomplete local coating may occur. On the other hand, the coating is difficult, and it is difficult to achieve coating with the help of tools. And the glue coating often requires 2 - 4 hours of pressure holding and shaping + 24 hours of standing, resulting in low processing efficiency of the temple 200 and increasing the processing cost of the entire smart glasses.

[0044] In this solution, the inner shell 220 and / or the outer shell 210 are fixed by the fixing fixture 120, so as to facilitate the placement of the hot-pressing adhesive film. The front of the splicing part of the inner shell 220 / or the outer shell 210 faces. The hot-pressing adhesive film is configured as a solid at room temperature. Therefore, the required hot-pressing adhesive film can be pre-cut according to the shape of the inner shell 220 and / or the outer shell 210 and the required amount of glue, so as to facilitate the placement of the hot-pressing adhesive film and reduce the possibility of glue overflow or incomplete local coating. After the hot-pressing adhesive film is placed at the splicing part of the outer shell 210 and / or the inner shell 220, the preheating device 130 heats the hot-pressing adhesive film, so that the hot-pressing adhesive film generates viscosity, and the hot-pressing adhesive film is pressed tightly on the outer shell 210 and / or the inner shell 220 by the extrusion of the preheating device 130, so as to fix the hot-pressing adhesive film at the splicing part of the outer shell 210 and / or the inner shell 220. Then, the inner shell 220 and / or the outer shell 210 with the hot-pressing adhesive film fixed are taken down and transferred to the heating and fixing module 140 for the next hot-pressing fixation.

[0045] Among them, the hot-pressing adhesive film often only needs to be coated on one of the spliced inner shell 220 and outer shell 210 to ensure the bonding stability. In this embodiment, the fixing fixture 120 is only used to fix the outer shell 210 and coat the hot-pressing adhesive film at its splicing part. In another embodiment, the fixing fixture 120 is only used to fix the inner shell 220 and coat the hot-pressing adhesive film at its splicing part. In other embodiments, the fixing fixture 120 is used to fix the inner shell 220 and the outer shell 210, and the hot-pressing adhesive film is respectively coated at the splicing parts of the inner shell 220 and the outer shell 210.

[0046] The inner shell 220 and / or the outer shell 210 with the hot-pressing adhesive film fixed are spliced through the pressing fixture 150 and further pressed and fixed so that the hot-pressing adhesive film is clamped at the splicing part of the inner shell 220 and the outer shell 210. Then, the pressing fixture 150 is heated by the heating device 160, and then the hot-pressing adhesive film is heated, so that the hot-pressing adhesive film bonds and fixes the inner shell 220 and the outer shell 210. The hot-pressing fixing time required for this hot-pressing form is relatively short, generally controllable within a few minutes. Compared with using traditional glue coating, this solution can greatly improve the bonding efficiency of the inner shell 220 and the outer shell 210. Moreover, in this solution, the preheating module 110 adopts a form in which the fixing fixture 120 and the preheating device 130 are separated, so that it is convenient for the operator to fix and take the inner shell 220 and / or the outer shell 210, thereby reducing the possibility of the operator accidentally touching the preheating press head 131 and reducing potential safety hazards. Similarly, in this solution, the heating and fixing module 140 adopts a form in which the pressing fixture 150 and the heating device 160 are separated, so that it is convenient for the operator to fix and take the inner shell 220 and the outer shell 210, thereby reducing the possibility of the operator accidentally touching the heating press head 166 and reducing potential safety hazards.

[0047] Among them, in this solution, the hot-pressing adhesive film uses a prefabricated hot-melt adhesive film, thus effectively reducing the possibility of glue overflow. And the hot-pressing time can be controlled within 3 minutes, thereby further accelerating the bonding efficiency of the inner shell 220 and the outer shell 210. And this solution has operational versatility and can be adapted to the bonding and fixing of various complex structures.

[0048] Further, referring to Figures 1 to 4 , a fixing groove 121 is formed on the fixing fixture 120, and the outer shell 210 and / or the inner shell 220 are fixed in the fixing groove 121. The preheating device 130 includes a preheating press head 131, and the preheating press head 131 covers the fixing groove 121 to press and heat the hot-pressing adhesive film. Specifically, the fixing groove 121 has a limiting effect on the outer shell 210 and / or the inner shell 220, thus effectively ensuring that the outer shell 210 and / or the inner shell 220 are fixed in the fixing groove 121. The fixing groove 121 has a first opening arranged upward to facilitate the user to place the hot-pressing adhesive film. The preheating press head 131 is preheated to a preset temperature and then covers the first opening of the fixing groove 121, thereby pressing and heating the hot-pressing adhesive film. After pressing for a period of time, the fixing groove 121 rises to facilitate the user to take it off.

[0049] To facilitate the taking or placing of the outer shell 210 and / or the inner shell 220, a second opening is provided on the side of the fixing groove 121. The first opening is used to facilitate the user to place the hot-pressing adhesive film and the preheating and pressing of the hot-pressing adhesive film. The outer shell 210 and / or the inner shell 220 partially protrude from the second opening, so as to facilitate the user to take the outer shell 210 and / or the inner shell 220. In other embodiments, the fixing groove 121 can also be configured as two spliced half-grooves. Before fixing the outer shell 210 or the inner shell 220, the two half-grooves are opened away from each other. First, place the outer shell 210 or the inner shell 220 in one of the half-grooves, and then the two half-grooves approach each other to fix the inner shell 220 or the outer shell 210, so as to facilitate subsequent operations. After the operation is completed, open the two half-grooves again; alternatively, the fixing jig 120 can also be directly configured as a fixing clamp, and the fixing clamp clamps the outer shell 210 and / or the inner shell 220.

[0050] Furthermore, the preheating device 130 includes a preheating control box 132, a preheating platform 133, and a sliding arm 134 slidably mounted on the preheating platform 133. The fixing jig 120 fixes the preheating platform 133, and the preheating press head 131 is installed on the sliding arm 134. The preheating control box 132 is electrically connected to the preheating press head 131. Specifically, the sliding arm 134 is configured as a three-axis robotic arm, that is, the sliding arm 134 can drive the preheating press head 131 to slide arbitrarily in three directions of the X-axis, Y-axis, and Z-axis, that is, the sliding arm 134 can drive the preheating press head 131 to move arbitrarily in space, thereby improving the movement flexibility of the preheating press head 131. And the fixing jig 120 is fixedly arranged, so that the user only needs to control the movement of the preheating press head 131, which is convenient for the preheating press head 131 to move to the fixing jig 120 through a preset path, contributing to the automation of the preheating module 110. Of course, in other embodiments, both the preheating press head 131 and the fixing jig 120 are slidably mounted on the preheating platform 133; or the preheating press head 131 is fixedly arranged, and the fixing jig 120 is movably mounted on the preheating platform 133. It is also possible to manually operate the preheating press head 131 by the user to the fixing jig 120.

[0051] The preheating control box 132 is electrically connected to the preheating press head 131 to control the preheating press head 131 to heat to a preset temperature. And a first control panel 111 and a first control switch 112 are provided on the preheating control box 132 and / or the preheating platform 133 to control the operation and movement path of the preheating press head 131. And there is also a first temperature controller 113 on the preheating control box 132. The first temperature controller 113 can control the maximum error of the preheating press head 131 within 0.5 °C, so as to ensure the surface temperature uniformity of the preheating press head 131 and the temperature stability during the movement process.

[0052] Further, the preheating device 130 further includes an adapter plate 135. The adapter plate 135 is fixed to the sliding arm 134. The preheating head 131 has a first guiding post 136 extending in a direction away from the preheating platform 133. The adapter plate 135 is correspondingly provided with a first guiding sleeve 137. The first guiding post 136 slidably passes through the first guiding sleeve 137. A first elastic member 138 is further provided between the preheating head 131 and the adapter plate 135. The first elastic member 138 makes the preheating head 131 tend to move away from the adapter plate 135.

[0053] The preheating head 131 is mounted on the sliding arm 134 through the adapter plate 135, which facilitates the installation of the preheating head 131. The first guiding post 136 extends vertically. The adapter plate 135 is correspondingly provided with a first guiding sleeve 137. The first guiding post 136 slidably passes through the first guiding sleeve 137. Thus, the preheating head 131 is movably mounted on the adapter plate 135 through the first guiding post 136 and moves up and down relative to the adapter plate 135 under the guidance of the first guiding post 136. A first elastic member 138 is further provided between the preheating head 131 and the adapter plate 135. The first elastic member 138 makes the preheating head 131 tend to move away from the adapter plate 135. When the sliding arm 134 drives the preheating head 131 to move above the fixing groove 121, it is pressed down until the preheating head 131 contacts the hot pressing adhesive film, and then continues to be pressed down. The preheating head 131 presses the hot pressing adhesive film through the first elastic member 138, thereby increasing the pressing force of the preheating head 131 on the hot pressing adhesive film.

[0054] To ensure that the preheating head 131 accurately presses the hot pressing adhesive film, in one embodiment, one of a first positioning post and a first positioning hole 122 is provided on one side of the preheating head 131 facing the fixing groove 121, and the other is provided on the periphery of the opening of the fixing groove 121 corresponding to the opening. The first positioning post is inserted into the first positioning hole 122. In this embodiment, the first positioning post is fixed to one side of the preheating head 131 facing the fixing groove 121, and the first positioning hole 122 is fixed to the periphery of the first opening of the fixing groove 121. When the preheating head 131 is about to contact the hot pressing adhesive film, the first positioning post is inserted into the first positioning hole 122, which further guides the downward pressing of the preheating head 131 and can also reduce the possibility of the hot pressing adhesive film shifting due to the oscillation of the preheating head 131 during the downward pressing process. In another embodiment, the first positioning hole 122 is fixed to one side of the preheating head 131 facing the fixing groove 121, and the first positioning post is fixed to the periphery of the first opening of the fixing groove 121.

[0055] The specific process of the preheating module 110 can be as follows (taking only the outer shell 210 coated with a hot-pressing adhesive film as an example): First, fix the outer shell 210 in the fixing groove 121 of the fixing jig 120, so that the joint of the outer shell 210 faces the opening of the fixing groove 121, and then place the hot-pressing adhesive film on the joint of the outer shell 210. At the same time, the preheating control box 132 controls the preheating press head 131 to heat to a preset temperature, and the sliding arm 134 drives the preheating press head 131 to move above the opening of the fixing groove 121 and press down until the preheating press head 131 is about to contact the hot-pressing adhesive film. The first positioning post is inserted into the first positioning hole 122, and continue to press down to the preheating press head 131. At this time, under the cooperation of the first guide post 136 and the first guide sleeve 137, the preheating press head 131 remains stationary, and under the action of the first elastic member 138, presses the hot-pressing adhesive film tightly, and after maintaining for a period of time, raises the preheating press head 131 and removes the outer shell 210. During the working process of the preheating press head 131, the temperature on its surface remains basically unchanged, so as to ensure uniform heating of the hot-pressing adhesive film. It should be noted that the working steps of the preheating module 110 are not limited to the above sequence. In this embodiment, for example, the fixing of the hot-pressing adhesive film and the heating of the preheating press head 131 are carried out simultaneously. In other embodiments, the hot-pressing adhesive film can also be fixed first, and then the preheating press head 131 is heated; or, the preheating press head 131 is heated first, and then the hot-pressing adhesive film is fixed. As long as the preheating process of the hot-pressing adhesive film requires the above steps, it is within the protection scope of the present invention.

[0056] Refer to Figure 1 、 Figures 5 to 10, for the sake of convenience of description, hereinafter, only the outer shell 210 coated with a hot-pressing adhesive film is taken as an example for illustration. In one embodiment, the pressing fixture 150 includes a first pressing portion 151 and a second pressing portion 152. The first pressing portion 151 is provided with a first limiting groove 151a adapted to the inner shell 220, and the second pressing portion 152 is provided with a second limiting groove 152a adapted to the outer shell 210. When the first pressing portion 151 and the second pressing portion 152 are spliced together, the first limiting groove 151a and the second limiting groove 152a are covered with each other, so that the inner shell 220 and the outer shell 210 are pressed and spliced together. Specifically, both the first pressing portion 151 and the second pressing portion 152 are configured as plate-like structures. The first pressing portion 151 is provided with the first limiting groove 151a, and the second pressing portion 152 is provided with the second limiting groove 152a. The outer shell 210 preheated by the preheating module 110 is snapped into the second limiting groove 152a. The shape of the second limiting groove 152a is similar to the outer contour of the outer shell 210, so that the two are adapted and the fixation of the outer shell 210 can be ensured. Similarly, the inner shell 220 is snapped into the first limiting groove 151a. The shape of the first limiting groove 151a is similar to the outer contour of the inner shell 220, so that the two are adapted and the fixation of the inner shell 220 can be ensured. The plane of the first pressing portion 151 having the first limiting groove 151a and the plane of the second pressing portion 152 having the second limiting groove 152a are close to each other and spliced, so that the first limiting groove 151a and the second limiting groove 152a are covered with each other, and further the inner shell 220 and the outer shell 210 are pressed and spliced together, thereby ensuring the splicing accuracy of the inner shell 220 and the outer shell 210. And in order to ensure the installation stability, both the first pressing portion 151 and the second pressing portion 152 are placed vertically.

[0057] In other embodiments, the pressing fixture 150 can also be configured as two pressing portions. One side of the two pressing portions is rotatably connected, and at least one of them can rotate relative to the other along the rotation axis of the two. The inner shell 220 and the outer shell 210 are respectively fixed to the two pressing portions. When pressing, the two jointly clamp the inner shell 220 and the outer shell 210.

[0058] To ensure that the pressing fixture 150 is not accidentally detached during the pressurization process, in one embodiment, refer to Figures 7 to 10, the first pressing part 151 is provided with a first fastening part 153, and the second pressing part 152 is provided with a second fastening part 154. When the first limiting groove 151a and the second limiting groove 152a are covered with each other, the first fastening part 153 and the second fastening part 154 are fastened to each other. Specifically, the first fastening part 153 and the second fastening part 154 are fastened to each other, so as to relatively fix the first pressing part 151 and the second pressing part 152, ensuring that the first pressing part 151 and the second pressing part 152 can continuously and stably apply pressure, thereby maintaining pressure for the spliced inner shell 220 and outer shell 210. In this embodiment, the first fastening part 153 is configured as a clamping groove, and the second fastening part 154 is configured as a clamping hook. After the first pressing part 151 and the second pressing part 152 press the inner shell 220 and the outer shell 210, the clamping hook hooks the clamping groove. In other embodiments, both the first fastening part 153 and the second fastening part 154 can be configured as clamping hooks. After the first pressing part 151 and the second pressing part 152 press the inner shell 220 and the outer shell 210, the two clamping hooks are hooked to each other.

[0059] To ensure the accurate splicing of the inner shell 220 and the outer shell 210, in one embodiment, the first pressing part 151 includes a first inner plate 151b and a first outer plate 151c. The first limiting groove 151a is provided on the first inner plate 151b. The second pressing part 152 includes a second inner plate 152b and a second outer plate 152c. The second limiting groove 152a is provided on the second inner plate 152b. The first outer plate 151c is provided with a second guiding post 155, and the second outer plate 152c is correspondingly provided with a second guiding sleeve 156. The second guiding post 155 is movably inserted through the second guiding sleeve 156;

[0060] A second elastic member is provided between the first inner plate 151b and the first outer plate 151c, and the second elastic member makes the first inner plate 151b tend to be away from the first outer plate 151c;

[0061] A third elastic member 152d is provided between the second inner plate 152b and the second outer plate 152c, and the third elastic member 152d makes the second inner plate 152b tend to be away from the second outer plate 152c.

[0062] Specifically, when the first pressing part 151 and the second pressing part 152 approach each other to a preset position, the second guide post 155 is inserted into the second guide sleeve 156. As the first pressing part 151 and the second pressing part 152 move further towards each other, the second guide post 155 slides within the second guide sleeve 156, thereby guiding the relative movement of the first pressing part 151 and the second pressing part 152 and ensuring the accurate splicing of the inner shell 220 and the outer shell 210. The first pressing part 151 includes a first inner plate 151b and a first outer plate 151c. The first inner plate 151b is movably installed inside the first outer plate 151c, and a second elastic member is provided between the first inner plate 151b and the first outer plate 151c. The second pressing part 152 includes a second inner plate 152b and a second outer plate 152c. The second inner plate 152b is movably installed inside the second outer plate 152c, such that the first inner plate 151b and the second inner plate 152b come into contact before the first outer plate 151c and the second outer plate 152c do. Then, under the action of the first elastic member 138 and the second elastic member, as the first outer plate 151c and the second outer plate 152c approach each other, the first inner plate 151b and the second inner plate 152b are gradually pressed against each other, thereby applying pressure to the splicing of the inner shell 220 and the outer shell 210. After maintaining the pressure for a period of time, the first outer plate 151c and the second outer plate 152c move away from each other, causing the pressure between the first inner plate 151b and the second inner plate 152b to be gradually released, and the bonding of the inner shell 220 and the outer shell 210 is completed. When the heating device 160 heats up, it can directly heat the first inner plate 151b and the second inner plate 152b, and then transfer the temperature to the hot pressing adhesive film for heating. Therefore, for the convenience of the heating device 160 to heat, through holes are provided on both the first outer plate 151c and the second outer plate 152c, enabling the heating device 160 to directly heat the first inner plate 151b and the second inner plate 152b through the through holes.

[0063] In another embodiment, the first pressing part 151 includes a first inner plate 151b and a first outer plate 151c. A first limiting groove 151a is provided on the first inner plate 151b. The second pressing part 152 includes a second inner plate 152b and a second outer plate 152c. A second limiting groove 152a is provided on the second inner plate 152b. The first inner plate 151b is movably installed on the first outer plate 151c. A second elastic member is provided between the first inner plate 151b and the first outer plate 151c, and the second elastic member causes the first inner plate 151b to have a tendency to move away from the first outer plate 151c. The second inner plate 152b is fixed to the second outer plate 152c.

[0064] In yet another embodiment, the first pressing portion 151 includes a first inner plate 151b and a first outer plate 151c. The first limiting groove 151a is provided on the first inner plate 151b. The second pressing portion 152 includes a second inner plate 152b and a second outer plate 152c. The second limiting groove 152a is provided on the second inner plate 152b. The second inner plate 152b is movably installed on the second outer plate 152c. A third elastic member 152d is provided between the second inner plate 152b and the second outer plate 152c. The third elastic member 152d causes the second inner plate 152b to have a tendency to move away from the second outer plate 152c. The first inner plate 151b is fixed to the first outer plate 151c.

[0065] Optionally, there are two first pressing portions 151 and two second pressing portions 152 that are spaced apart. A frame fixing portion 157 is further provided between the two first pressing portions 151. The frame is pre-fixed to the frame fixing portion 157 so that when the inner shells 220 and the outer shells 210 of the two temple arms 200 are press-fitted and fixed, they are rotatably installed on the frame. Specifically, since a general smart glasses has two temple arms 200, there are two first pressing portions 151 and two second pressing portions 152 that are spaced apart. The two first pressing portions 151 are arranged back to back and spaced apart. The two second pressing portions 152 are respectively provided on the outer sides of the first pressing portions 151, so that the two first pressing portions 151 and the second pressing portions 152 respectively press the two temple arms 200. There are often structures such as an internal skeleton and conductive circuits between the inner shell 220 and the outer shell 210. For example, the internal skeleton and the conductive circuits are respectively fixed to the inner shell 220. When the inner shell 220 and the outer shell 210 are spliced, the assembly of the entire temple arm 200 is completed. And to further improve the integrity of the smart glasses, when the inner shell 220 and the outer shell 210 are spliced, the rotational installation of the temple arm 200 and the frame can be completed (such as the frame is pre-rotatably assembled with the internal skeleton or the inner shell 220 in advance, and the frame has no connection relationship with the outer shell 210. When the outer shell 210 and the inner shell 220 are spliced, the assembly of the temple arm 200 and the frame is completed). Therefore, a frame fixing portion 157 is further provided between the two first pressing portions 151. The frame is pre-fixed to the frame fixing portion 157 to facilitate the assembly of the smart glasses. It should be emphasized that the frame fixing portion 157 is provided between the two first pressing portions 151, but the frame fixing portion 157 is not arranged on the midline of the two first pressing portions 151. More often, the frame fixing portion 157 is provided on one side of the two first pressing portions 151. The specific position and form of the frame fixing portion 157 can be set according to the specific structure of the smart glasses.

[0066] Moreover, to ensure the integrity of the pressing fixture 150, the two first pressing parts 151 are relatively fixed through a connecting plate 158. The second pressing part 152 can move closer to or farther away from the first pressing part 151 to facilitate the installation of the inner shell 220 and the outer shell 210. The frame fixing part 157 is also fixed to the connecting plate 158 to facilitate the overall transfer of the pressing fixture 150 during subsequent heating.

[0067] Referring to Figures 5 to 10 , in order to facilitate the processing of the heating device 160, in one embodiment, the heating device 160 includes a heating platform 161. The heating platform 161 has an assembly area 162 for the pressing fixture 150 and a heating area 163 for heating the pressing fixture 150. One of the pressing fixture 150 and the assembly area 162 is provided with a second positioning post 164, and the other is correspondingly provided with a second positioning hole. The second positioning post 164 is inserted into the second positioning hole. Specifically, the heating platform 161 is divided into two areas, namely the assembly area 162 and the heating area 163. When not heating, the pressing fixture 150 is arranged in the assembly area 162. The inner shell 220 and the outer shell 210 are spliced and pressed in the assembly area 162, and then the whole is transferred to the heating area 163 for heating and pressure maintaining. The assembly area 162 and the heating area 163 are independently partitioned. On the one hand, it facilitates the installation of the inner shell 220 and the outer shell 210. On the other hand, it reduces the possibility of scalding the operator when taking and assembling the inner shell 220 and the outer shell 210.

[0068] Moreover, to reduce the possibility of accidental displacement of the pressing fixture 150 during the assembly process, in this embodiment, the pressing fixture 150 is provided with a second positioning post 164, and the assembly area 162 is provided with a second positioning hole. The second positioning post 164 is inserted into the second positioning hole. In other embodiments, the assembly area 162 is provided with a second positioning post 164, and the pressing fixture 150 is provided with a second positioning hole. The second positioning post 164 is inserted into the second positioning hole. Among them, the mutual transfer of the pressing fixture 150 between the assembly area 162 and the heating area 163 can be achieved by a robotic arm grabbing or by manual transfer.

[0069] Further, the heating device 160 further includes a heating control box 165 and a heating head 166 disposed in the heating area 163. The heating control box 165 is electrically connected to the heating head 166. When the pressing fixture 150 is disposed in the heating area 163, the heating head 166 heats and presses against the first pressing portion 151 and / or the second pressing portion 152 to bond and fix the inner shell 220 and the outer shell 210. Specifically, the heating head 166 passes through the through hole and contacts the first inner plate 151b and / or the second inner plate 152b, and then transfers the temperature to heat the thermocompression adhesive film. This heating method can also reduce the overheating of the first outer plate 151c and the second outer plate 152c after heating, which is not conducive to disassembly. The heating control box 165 is electrically connected to the heating head 166 to control the heating head 166 to heat to a preset temperature. A second control panel 141 and a second control switch 142 are provided on the heating control box 165 and / or the heating platform 161 to control the operation and movement path of the heating head 166. A second temperature controller 143 is also provided on the heating control box 165. The second temperature controller 143 can control the maximum error of the heating head 166 within 0.5 °C, so as to ensure the surface temperature uniformity of the heating head 166 and the temperature stability during the movement process.

[0070] To further protect the temple 200 during the heating process and reduce heat radiation, in one embodiment, a protective cover 167 is further provided on the heating area 163. The protective cover 167 covers the pressing fixture 150 and the heating head 166. At this time, in order to facilitate the placement of the pressing fixture 150 in the heating area 163, a guide rail can be provided in the processing area. The heating head 166 is installed on the guide rail. When it is necessary to transfer the pressing fixture 150, it slides out of the covering range of the protective cover 167 through the guide rail, and then the placement of the pressing fixture 150 and the assembly of the heating head 166 are completed, and then it slides back into the covering range of the protective cover 167. Or the protective cover 167 can be removed first, and after the placement of the pressing fixture 150 and the assembly of the heating head 166 are completed, the protective cover 167 is installed again.

[0071] The specific process of the heating and fixing module 140 can be as follows (taking only the outer shell 210 coated with a hot pressing adhesive film as an example): The pressing fixture 150 is arranged in the assembly area 162. First, the first pressing part 151 is moved away from the second pressing part 152, and then the inner shell 220 is fixed in the first limiting groove 151a of the first inner plate 151b, and the outer shell 210 is fixed in the second limiting groove 152a of the second inner plate 152b. When the first pressing part 151 and the second pressing part 152 approach each other to a preset position, the second guide post 155 is inserted into the second guide sleeve 156. As the first pressing part 151 and the second pressing part 152 move further towards each other, the first inner plate 151b and the second inner plate 152b come into contact with each other. Then, under the action of the first elastic member 138 and the second elastic member, as the first outer plate 151c and the second outer plate 152c approach each other, the first inner plate 151b and the second inner plate 152b are gradually pressed against each other, thereby applying pressure to the splicing of the inner shell 220 and the outer shell 210. Then, the first fastening part 153 and the second fastening part 154 are fastened to each other to complete the assembly.

[0072] At the same time, the heating control box 165 controls the heating head 166 to heat to a preset temperature, and then transfers the pressing fixture 150 to the heating area 163. The heating head 166 passes through the through hole and contacts the first inner plate 151b and / or the second inner plate 152b, and then transfers the temperature to heat the hot pressing adhesive film. After heating and maintaining pressure for a period of time, it is transferred back to the assembly area 162. After removing the first pressing part 151, the temple 200 is removed. It should be noted that the working steps of the heating and fixing module 140 are not limited to the above sequence. For example, in this embodiment, the splicing of the inner shell and the outer shell is carried out simultaneously with the heating of the heating head 166. In other embodiments, the splicing of the inner shell and the outer shell can also be carried out first, and then the heating of the heating head 166 is completed; or, the heating of the heating head 166 is carried out first, and then the splicing of the inner shell and the outer shell is carried out. As long as the above steps are required for the heating and fixing process of the inner shell and the outer shell, they are all within the protection scope of the present invention.

[0073] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
