Detailed Implementation

[0038] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Please see Figure 3 As shown, the processing method for the VR glasses frame in this embodiment includes:

[0041] S1. Real-time acquisition of position information of the pre-processing area of ​​the shell placed in the placement cavity of the lower mold and the fixed cavity of the upper mold;

[0042] S2. Set the motion path of the upper mold based on the collected position information;

[0043] S3. Control the upper mold to move towards the lower mold along the motion path, so that the foam is aligned and attached to the pre-processed area of ​​the shell.

[0044] Specifically, before real-time acquisition of the position information of the pre-processed area of ​​the housing placed in the lower mold's placement cavity and the fixed cavity of the upper mold, the process also includes:

[0045] S101. Place the shell in the placement cavity;

[0046] S102. Place the adhesive film in the pre-processing area of ​​the housing with the film aligned.

[0047] S103. Make foam that matches the shell and fix the foam in the fixing cavity.

[0048] It should be noted that the upper mold of the present invention has foam fixed in its fixed cavity. The processing method of VR glasses frame can first collect the position information of the fixed cavity of the upper mold and the pre-processing area, and then set the movement path of the upper mold according to the collected position information. The upper mold moves along the movement path, so that the foam can be accurately attached to the pre-processing area. Compared with manually aligning the foam and the pre-processing area of ​​the shell and attaching them, the production efficiency of the present invention is greatly improved, and it can be accurately aligned, avoiding the problem of foam displacement.

[0049] Specifically, after controlling the upper mold to move towards the lower mold along the motion path, so that the foam is aligned and adhered to the pre-processed area of ​​the shell, it also includes:

[0050] S4, Pressed foam and shell;

[0051] S5. Heat the adhesive film to bond and fix the shell and foam together.

[0052] Specifically, after pressing the foam and the shell, it also includes:

[0053] S6, Start timing;

[0054] After heating the adhesive film to bond and fix the housing and foam, the process also includes:

[0055] S7. When the timing reaches the first preset time, stop heating and control the separation of the lower mold and the upper mold;

[0056] S8. Cooling film is used to make a shell that fits the foam.

[0057] The adhesive film of this invention is a hot melt adhesive. Before use, it can be used to wrap the pre-processed area. Then, the foam is moved and wrapped with the hot melt adhesive, which is located between the foam and the shell. Heating the hot melt adhesive at this time can activate its activity and bond the foam and the shell together. Compared with the traditional method of applying glue to the pre-processed area of ​​the shell and then bonding the shell and the foam, this invention can avoid the foam not being firmly bonded to the shell due to the fast drying of the glue. After bonding, the hot melt adhesive can be cooled quickly to speed up the processing efficiency. In this embodiment, after multiple practices, in order to ensure the bonding quality, the heating temperature is set to 130±10℃, the cooling temperature is 24±4℃, and the pressing time is 80±10s. Of course, in actual applications, people can adjust the parameters according to their own needs. This invention does not limit this.

[0058] Accordingly, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the present invention also designs a processing device for VR glasses frames, which includes a lower mold, an upper mold 3, a detection mechanism 1 and a controller 2. The lower mold is provided with a placement cavity 13 for placing the shell, and the upper mold is provided with a fixing cavity 10 for fixing the foam. The controller 2 is electrically connected to the detection mechanism 1 and the upper mold 3.

[0059] The detection mechanism 1 is used to collect the position information of the fixed cavity 10 and the pre-processed area of ​​the shell in real time; the controller 2 is used to set the movement path of the upper mold 3 according to the collected position information, and control the upper mold 3 to move towards the lower mold according to the movement path, so that the foam is aligned and attached to the pre-processed area of ​​the shell.

[0060] It should be noted that the lower mold of the present invention not only has a placement cavity 13, but also a fixing member and a second limiting block 12. The upper mold has two first limiting blocks 11, and the space between the two first limiting blocks 11 matches the second limiting block 12. The shell is placed in the placement cavity 13 and fixed by the fixing member, which ensures that the shell does not shift in the placement cavity 13. After it is fixed, the detection mechanism 1 can identify the pre-processed area of ​​the shell. The controller 2 controls the movement of the upper mold 3 according to the pre-processed area detected by the detection mechanism 1. The first limiting block 11 and the second limiting block 12 enable the foam to be aligned with the pre-processed area before being bonded to the shell. The present invention does not rely on manual labor and can make the foam reliably bonded to the pre-processed area of ​​the shell, which greatly improves production efficiency and avoids the problem of greatly increased product defect rate caused by foam displacement.

[0061] Specifically, the upper mold is also provided with a receiving cavity, and the fixed cavity 10 is provided with several through holes communicating with the receiving cavity. A vacuuming mechanism is connected to the receiving cavity, which is used to perform vacuuming operations on the receiving cavity. In this embodiment, the foam can be tightly attached to the fixed cavity 10 simply by activating the vacuuming mechanism. When the foam adheres to the pre-processed area of ​​the shell, the vacuuming mechanism is turned off to move the upper mold 3 away from the shell, which is very convenient. Of course, it should be noted that in practical applications, other devices can be used to replace the vacuum mechanism, and this invention does not limit this.

[0062] Specifically, the VR glasses frame processing device also includes an adhesive applicator 4 for placing the adhesive film in the pre-processing area, and the adhesive applicator 4 is electrically connected to the controller 2. In this embodiment, the controller 2 controls the movement of the adhesive applicator 4 based on the position information of the pre-processing area. The adhesive applicator 4 accurately places the adhesive film in the pre-processing area. Compared with the traditional method of applying glue to the pre-processing area, this invention can avoid the problem of some areas of the pre-processing area not being glued, which would weaken the adhesion between the foam and the shell or cause glue to be applied outside the pre-processing area, resulting in product defects.

[0063] Specifically, the VR glasses frame processing device also includes a sensor 6 and a heating element 5 for heating the adhesive film. The sensor 6 is mounted on the lower mold, and the controller 2 is electrically connected to the sensor 6 and the heating element 5. In this embodiment, when the sensor 6 senses pressure on the housing, it sends a signal to the controller 2. The controller 2 can then activate the heating element 5, which in turn activates the adhesive properties of the hot melt adhesive, bonding the housing and the foam together.

[0064] Specifically, the VR glasses frame processing device also includes a cooling mechanism 7 for cooling the adhesive film, which is electrically connected to the controller 2. In this embodiment, when the sensor 6 senses that the temperature of the housing exceeds a first threshold and the housing is not subjected to pressure, it sends a signal to the controller 2. The controller 2 can then activate the cooling mechanism 7, which rapidly solidifies the hot melt adhesive, thus accelerating production efficiency.

[0065] This invention utilizes heated hot melt adhesive to bond the shell and foam together. Then, the upper mold 3 can be controlled to move away from the lower mold. When the sensing element 6 detects that the lower mold is not being pressed by the upper mold 3 and the shell temperature exceeds a first threshold of 50 degrees Celsius, the cooling mechanism 7 is activated to rapidly cool the shell and hot melt adhesive, facilitating manual handling. It should be noted that this invention involves heating or cooling the shell, with the shell transferring heat to the hot melt adhesive. In practical applications, people can also directly heat or cool the hot melt adhesive, and the reading of the first threshold can be set independently; this invention does not limit this.

[0066] Specifically, the VR glasses frame processing device also includes an adjustment unit 9 and a timing unit 8 for real-time detection of the pressing time of the shell and foam. The timing unit 8 is electrically connected to the controller 2 and the sensor 6, respectively. The adjustment unit 9 is electrically connected to the heating element 5 and the cooling mechanism 7 to adjust the heating temperature of the heating element and the cooling temperature of the cooling mechanism.

[0067] In this embodiment, a timing unit 8 is provided for easy tracking of the pressing time, and an adjustment unit 9 is provided for easy adjustment of the heating and cooling temperatures. Users can easily set the corresponding parameters according to their needs. It should be noted that, in this embodiment, to ensure the bonding effect, the pressing time is set to 80±10s, the heating temperature to 130±10℃, and the cooling temperature to 24±4℃. It should also be noted that the shell of this invention has a melting point exceeding 130 degrees Celsius, while the hot melt adhesive has a melting point below 130 degrees Celsius. At 130 degrees Celsius, the hot melt adhesive can melt and bond the shell and the foam.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0069] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
