DETAILED DESCRIPTION

[0025] A universal folding and shaping jig of the utility model is described in detail below in conjunction with the accompanying drawings.

[0026] A soft film 14 is provided on the VR glasses frame 13, and a pair of perforations are provided on the soft film 14. The rubber ring 12 is provided at the perforations and is shaped with the soft film 14 by heat pressing. How to accurately shape the soft film 14 and the rubber ring 12 is as follows:

[0027] like Figure 1 As shown, an embodiment of a universal folding and shaping fixture of the utility model includes a base plate 1 and a support seat 2 fixedly arranged on the base plate 1, a pair of mirror-arranged mounting grooves 201 are provided on the support seat 2, and each mounting groove 201 is equipped with a bearing component for supporting and positioning the rubber ring 12, and a pair of rubber rings 12 are placed on different bearing components respectively, and the rubber rings 12 are positioned by the bearing components to improve the accuracy during hot pressing and the success rate after hot pressing. Further, a pair of shell placement platforms 11 for supporting VR glasses frames 13 are provided on the top of the support seat 2, and the shell placement platform 11 can not only support the VR glasses frame 13, but also position the VR glasses frame 13, so that the VR glasses frame 13 can be placed in the designated hot pressing position; a high-temperature pressure-keeping mold 3 that can be lifted and lowered is provided above the support seat 2, and the high-temperature pressure-keeping mold 3 is installed on a lifting mechanism placed on the side of the support seat 2, and the lifting and lowering movement of the high-temperature pressure-keeping mold 3 is controlled by the lifting mechanism. First, place a pair of rubber rings 12 on different bearing components respectively, and then place the VR glasses frame 13 on the shell placement table 11, position the rubber ring 12 through the bearing components, and position the VR glasses frame 13 through the shell placement table 11, so that the rubber ring 12 is aligned with the perforation on the soft film 14, and then operate the lifting mechanism placed next to the support seat 2 to control the high-temperature pressure-keeping mold 3 to move downward, and press the soft film 14 and the rubber ring 12 through the high-temperature pressure-keeping mold 3 to make the soft film 14 and the rubber ring 12 fit together, and finally heat the high-temperature pressure-keeping mold 3. After pressing for 8 to 9 seconds under high temperature, the lifting mechanism controls the high-temperature pressure-keeping mold 3 to reset upward, thereby completing the hot pressing treatment of the rubber ring 12, and the rubber ring 12 and the soft film 14 are finalized.

[0028] like Figure 2-3As shown, the bearing component includes a support block 4 for supporting the rubber ring 12, and a plurality of legs 401 are provided at the bottom of the support block 4. The legs 401 are fixed to the inner bottom of the mounting groove 201 through a first fixing bolt 402. The support block 4 is stably installed in the mounting groove 201 through the plurality of legs 401 and the first fixing bolt 402. A placement groove 403 for placing the rubber ring 12 is provided on the circumferential side of the top of the support block 4. Under the action of the placement groove 403, the rubber ring 12 is conveniently placed on the support block 4. In addition, when hot pressing is required for rubber rings 12 of different sizes, the first fixing bolt 402 is loosened to replace support blocks 4 of different models, thereby improving the practicality of the jig.

[0029] Furthermore, in order to position the rubber ring 12 placed in the placement groove 403, a movable plate 5 is slidably provided on the support leg 401, and the sliding direction of the movable plate 5 is consistent with the depth direction of the placement groove 403, so that the movable plate 5 can move on the support leg 401 in the direction of approaching or moving away from the placement groove 403. Among them, a limit frame 8 sleeved on the outside of the support block 4 is fixedly connected to the movable plate 5, and the limit frame 8 and the placement groove 403 are surrounded to form a positioning groove for positioning the placed rubber ring 12, and the top surface of the limit frame 8 is higher than the top surface of the support block 4, so that under the cooperation of the limit frame 8 and the placement groove 403, it is convenient to accurately place the rubber ring 12 at the designated processing position (i.e., in the placement groove 403), and after being placed, the rubber ring 12 will not easily fall out of the placement groove 403. In addition, when the movable plate 5 slides on the support leg 401 in a direction away from the placement groove 403, it moves with the limit frame 8 until the top surface of the limit frame 8 is lower than the top surface of the support block 4, so that when the high-temperature pressure-maintaining mold 3 presses the soft film 14 and the rubber ring 12, the soft film 14 can fully fit with the rubber ring 12, so as to improve the hot pressing effect of the jig, make the rubber ring 12 and the soft film 14 more stably fixed, and improve the success rate of the processing. After the processing is completed, the movable plate 5 and the limit frame 8 need to be reset to the initial position.

[0030] like Figure 4-5As shown, in order to enable the movable plate 5 to automatically move toward or away from the placement slot 403, a through hole 7 is provided in the middle of the support block 4, and a pressing block 6 is fixedly provided on the movable plate 5 by a second fixing bolt 601, and the pressing block 6 is placed in the through hole 7; when a force is applied to the pressing block 6, the movable plate 5 is pushed to move in a direction away from the placement slot 403. In addition, a plurality of chambers 10 are provided at the bottom of the installation slot 201, and a plurality of springs 9 placed in the chambers 10 are provided at the bottom of the movable plate 5; when a force is applied to the pressing block 6 to enable the movable plate 5 to move in a direction away from the placement slot 403, the springs 9 placed in the chambers 10 will be compressed, and when the force is stopped on the pressing block 6, under the action of the compressed spring 9, the spring 9 pushes the movable plate 5 to reset, so that the top surface of the limit frame 8 is higher than the top surface of the support block 4 again.

[0031] Furthermore, the top surface of the pressing block 6 is higher than the top surface of the limit frame 8, and a pair of rubber rings 12 are placed on different bearing components respectively, and then the VR glasses frame 13 is placed on the shell placement table 11, and then the lifting mechanism placed next to the support seat 2 is operated to control the high-temperature pressure-holding mold 3 to move downward. During the downward movement, the high-temperature pressure-holding mold 3 will first contact the pressing block 6, and the high-temperature pressure-holding mold 3 will apply force to the pressing block 6; when the top surface of the limit frame 8 is pressed to be lower than the top surface of the support block 4, the high-temperature pressure-holding mold 3 is used to press the soft film 14 and the rubber ring 12, so that the soft film 14 and the rubber ring 12 are fitted together, and finally the high-temperature pressure-holding mold 3 is heated. After pressing for 8 to 9 seconds under high temperature, the lifting mechanism controls the high-temperature pressure-holding mold 3 to reset upward, thereby completing the hot pressing treatment of the rubber ring 12, and the rubber ring 12 and the soft film 14 are finalized; and, under the action of the spring 9, the movable plate 5 and the limit frame 8 are pushed to reset.
