Description

Technical Field

[0002] LED lamp tubes, also often called light tubes or fluorescent tubes, are mainly composed of LED light-emitting diodes, brackets, lampshades, drive circuits and heat sinks. Common materials for LED lampshades are glass, PMMA (polymethyl methacrylate), PC (polycarbonate), etc. They have the characteristics of high transparency, corrosion resistance, and UV resistance. During the production process of cylindrical glass lamp tubes, due to space limitations or design requirements, they may need to be cut into shorter lengths or specific shapes in order to better adapt to the use environment, thus requiring the use of cutting devices.

[0003] When the existing cutting equipment is used, after cutting the two ends of the glass tube, it is often necessary to anneal the cut end surface. Although the annealing treatment can remove some defects such as burrs and cracks on the cut end surface, there is no way to fully and thoroughly solve the burrs and cracks on the cut end surface of the glass tube, so that the cut end surface is not smooth enough, which reduces the yield rate; and after the existing cutting equipment cuts the glass tube, the glass tubes are piled up, and intermittent unloading cannot be achieved to facilitate the subsequent continuous lamp tube processing process, which reduces the processing efficiency of the lamp tube.

[0029] Working principle: when the glass lamp tube needs to be cut, the glass lamp tube is continuously transported to the conveyor 6 by the external conveying equipment, and the conveyor 6 intermittently transports the glass lamp tube to the bottom of the laser emitting end of the laser cutting machine 10. At this time, the glass tube stays under the laser emitting end and rotates continuously. The laser cutting machine 10 is started so that the two laser emitting ends of the laser cutting machine 10 emit lasers to perform laser cutting on both ends of the glass lamp tube. After the cutting is completed, the cut glass lamp tube continues to move backward until it rolls down along the inclined platform 7 and is blocked by the baffle 403, thereby completing the cutting of the glass lamp tube;

[0030] When it is necessary to polish the cut end of the glass lamp tube after cutting, the fourth motor 502 is started to rotate a quarter of a turn, driving the third connecting shaft 503 to rotate a quarter of a turn, thereby driving the first special-shaped gear 505 and the second special-shaped gear 506 to rotate a quarter of a turn in the clockwise direction with the third connecting shaft 503 as the axis, thereby driving the third special-shaped gear 507 arranged opposite to the second special-shaped gear 506 to rotate half a turn with the fixed shaft 504 as the axis, thereby driving the corresponding rotating sleeve 508 and the fifth spur gear 510 to rotate half a turn with the fixed shaft 504 as the axis, thereby driving the sixth spur gear to rotate one turn with the short shaft as the axis, and the seventh synchronous belt and the first synchronous belt are connected to the first special-shaped gear 505 and the second special-shaped gear 506. The transmission action of the seven synchronous wheels drives the second transmission shaft 409 to rotate one circle, and then drives the second rotating disk 410 and the cylindrical pin to rotate one circle with the second transmission shaft 409 as the axis, and then drives the reciprocating rod 408 and the fourth rack 407 to reciprocate one round, and then drives the seventh spur gear 406 and the swing bar 411 to reciprocate one round with the first transmission shaft 405 as the axis, and then drives the two lifting plates 412 and the baffle 403 to move one round, so that the glass lamp tube located between the two baffles 403 continues to roll down along the inclined platform 7 and is stuck in the groove at the bottom end of the inclined platform 7, and is located directly below the grinding mechanism 2, ready for the grinding operation of the glass lamp tube;

[0031] Limiting the glass lamp tube: Start the second cylinder 306 to extend it, drive the grinding mechanism 2 to move downward, until the axis of the fixed tube 206 coincides with the axis of the glass lamp tube, at this time, the two fixed tubes 206 are respectively located at the two ends of the glass lamp tube, start the first motor 202 to rotate, drive the bidirectional screw 203 to rotate, and then drive the two moving blocks 204 to move closer to each other, and then drive the two fixed tubes 206 to move closer to each other, and insert the two ends of the glass lamp tube into the interior of the glass lamp tube until the two first grinding rollers 229 are respectively on the inner wall and outer wall of the cut end of the glass lamp tube. The second grinding roller 231 contacts the cutting surface of the cutting end. At this time, the first cylinder 209 is started to extend or shorten, driving the connecting block 210 and the first rack 211 to move, thereby driving the first spur gear 212 and the one-way screw 213 to rotate with the first rotating shaft 208 as the axis, thereby driving the internal thread sleeve 214 to move toward the direction close to the fixed plate, thereby driving the connecting strip 215 to move, thereby driving the multiple clamping strips 216 to expand outward to clamp and limit the glass lamp tube, so that the cutting end of the glass lamp tube has a stronger structural stability during grinding;

[0032] Start grinding the cut end of the glass lamp tube: start the second motor 217 to rotate, drive the second rotating shaft 218 to rotate, and then drive the second spur gear 219 to rotate with the second rotating shaft 218 as the axis, and then drive the gear ring 220 and the rotating cover 221 to rotate rapidly with the first rotating shaft 208 as the axis, and then drive the first grinding roller 229 and the second grinding roller 231 to rotate rapidly with the first rotating shaft 208 as the axis. In this process, start the third motor 222 to rotate and drive the third rotating shaft 223 to rotate, and then drive the fourth The rotating shaft 224 and the fifth rotating shaft 225 rotate, thereby driving the two first grinding rollers 229 to rotate with the fifth rotating shaft 225 and the sixth rotating shaft 228 as the axis respectively, so that the two first grinding rollers 229 grind the inner wall and the outer wall of the cut end respectively. At the same time, the third rotating shaft 223 rotates to drive the first connecting shaft 230 to rotate, thereby driving the second grinding roller 231 to rotate rapidly with the second connecting shaft as the axis, so that the second grinding roller 231 grinds the end surface of the cut end, thereby completing the grinding operation of the two ends of the glass lamp tube;

[0033] After the grinding is completed, the glass lamp tube needs to be unloaded: start the second cylinder 306 to shorten it, drive the polished glass lamp tube to move to the set position above the inclined platform 7, start the fourth motor 502 to continue to rotate a quarter turn (the second quarter turn), and then drive the first special-shaped gear 505 and the second special-shaped gear 506 to rotate a quarter turn. In this process, the first special-shaped gear 505 rotates to drive the third special-shaped gear 507 arranged opposite to it to rotate half a turn, and then drive the fourth connecting shaft 509 to rotate half a turn, and then drive the first rotating disk 304 to rotate half a turn with the fifth connecting shaft 303 as the axis, and then drive the connecting rod 305 to rotate along the set trajectory. Move, thereby driving the moving plate 301 and the second cylinder 306 to move the set distance, thereby driving the polished glass lamp tube to move to the top of one of the grooves on the feeder 8, and then starting the second cylinder 306 to extend it, driving the glass lamp tube to move to the groove, and restoring the first motor 202 and other electrical equipment included in the polishing mechanism 2 to their original state, so that the glass lamp tube falls into the groove, and starting the feeder 8 to operate it, driving the glass lamp tube to leave to the next position, and making the new groove replace the previous groove, and starting the fourth motor 502 again to make it continue to rotate half a circle, driving the polishing mechanism 2 to return to its original position, and preparing for the next glass lamp tube cutting process.
