Description

Technical Field

[0001] The present invention relates to the technical field of VR equipment manufacturing, and in particular to a head strap processing and cutting device for a head-mounted VR equipment. Background Art

[0002] The head strap of a head-mounted VR device plays a vital role in the VR experience. It enhances the stability of the VR helmet and ensures that the helmet does not slip or shake when the user performs various actions. By fitting tightly to the user's head, the head strap can provide a stable support, allowing the user to focus more on the experience of the virtual world without worrying about the helmet falling off or moving. In order to adapt to the head shapes of different users, the head strap usually adopts an adjustable design, so in the process of processing the head strap, it is usually necessary to cut the head strap to a fixed length to meet the needs of use.

[0003] The patent document with announcement number CN217318200U discloses a cutting device for processing head straps for head-mounted VR equipment, comprising a base, a support plate connected to one side of the top of the base, a material transport mechanism arranged on the top of the base, the material transport mechanism comprising a support frame, a feeding wheel, and a cutting table, the support frame being connected to the top of the base, the cutting table being connected between the support frames, the feeding wheels being connected between the support frames and located at the front and rear of the cutting table, and a cutting mechanism being arranged on one side of the support plate close to the material transport mechanism, and the beneficial effect is that: through the cooperation of the cutting mechanism and the limiting mechanism, the moving direction and moving speed of the cutter are the same as those of the head strap when the cutter is cutting, so that the cutter and the head strap are relatively stationary, and the curling of the head strap is avoided, and in addition, by arranging a collecting mechanism, the cut small sections will fall into the collecting mechanism, which is convenient for manual collection and sorting, but the patent still has the following problems in actual use: The cutting device achieves the effect of conveying the head strap to the cutter for cutting by setting a feeding wheel. However, after the cutting device completes a single cut of the head strap, it is difficult to quickly extend the feeding material out of the head strap and reconnect it with the feeding wheel, and it is also difficult to cut the head strap to a fixed length, resulting in poor continuity during operation of the cutting device, which affects the processing and cutting efficiency of the head strap of the VR device. In addition, the width of the feeding roller of the cutting device is difficult to adjust according to the specifications of the head strap during use, which can easily cause the head strap to tilt inside the feeding roller, resulting in an inclined cutting angle and affecting the accuracy of the cutting length of the head strap.

[0004] Therefore, we propose a head strap processing and cutting device for head-mounted VR equipment to solve the above-mentioned problems. Summary of the invention

By preventing the displacement of the head strap when the feeding roller 211 moves, the cutting stability effect is improved.

[0032] Working principle: Figure 1-Figure 11As shown, when using the device, first, the adjusting screw 215 is rotated by rotating the rotating handle 216, so that the adjusting screw 215 drives the end ring 212 close to the rotating handle 216 to move on the adjusting screw 215 and the moving rod 214, and drives the sliding ring 217 to be retracted and extended through the telescopic frame 213, and then the adjusting block 206 is pressed to separate the adjusting block 206 from the limit block 205, and rotated to the side of the reset spring 207, so that the adjusting block 206 drives the adjusting block 203 to rotate, and separates the adjusting block 203 from the fixed ratchet 202 at the end of the feeding slider 201, and then pulls the mounting frame 204 to unfold the mounting frame 204.

[0033] Secondly, place the head strap of the head-mounted VR device in the middle of the discharge slot 112 at the top of the workbench 110, pass the end of the head strap through the slot 113, and then pass through the guide roller 114 and the middle of the workbench 110, align the end of the head strap in the middle of the guide block 228, and place the end of the head strap on the lower end of the pressing block 308 close to the workbench 110, then move the mounting frame 204 to one side of the stand 301, and press the mounting frame 204 to make the feeding roller 211 contact with the head strap, and rotate the lifting screw 227 to make the lifting screw 227 drive the guide block 228 to slide on the extension plate 225 to a suitable height through the lifting rod 226, then loosen the fixing knob 104, and slide the sliding seat 103 in the sliding slot 102 to a position suitable for cutting the head strap.

[0034] Next, the cylinder 309 is controlled to make the lifting seat 303 descend to the bottom end of the lifting groove 302, and the pressing block 308 contacts the end of the head strap. Then, the motor 108 on one side of the control support frame 106 drives the threaded rod 109 to rotate, so that the threaded rod 109 drives the feeding slider 201 to slide on the sliding rod 107 above the base 101. At the same time, the friction wheel 219 on the side of the guide block 228 rotates on the workbench 110, so that the swing plate 222 slides in the middle of the curved groove 220 through the sliding block 221, and at the same time, the swing plate 222 rotates on the rotating seat 224 through the rotating shaft 223, so that the swing plate 222 and the guide block 228 push the head strap to fall in the middle of the guide plate 218, and then the limiting ratchet 210 at the end of the feeding roller 211 slides on the limiting block 208, and the limiting block 208 shrinks toward the limiting spring 209.

[0035] Finally, when the feeding slider 201 contacts the sensor 105, the cylinder 309 controls the lifting seat 303 to rise. At this time, the threaded rod 109 reverses, so that the feeding roller 211 is limited by the limiting block 208 and does not rotate, and drives the head strap to move toward the stand 301. When the mounting frame 204 moves to the stand 301, the cylinder 309 controls the lifting seat 303 to descend to the bottom of the lifting slot 302. At this time, the pressing guide rod 306 at the top of the pressing block 308 slides in the fixed plate 305, and the pressing spring 307 contracts, and the cutting knife 304 cuts the head strap, that is, the cutting of the head strap is completed. Then, when the feeding slider 201 triggers the sensor 105 again, the pressing block 308 rises, and the cut head strap falls into the storage slot 111.
