[0002] Existing automotive headlight lenses are generally made from optical glass. During the processing, the optical glass raw materials need to be prepared into blocks, and then the blocks are heated and softened, and then molded, annealed, polished, and finally processed into automotive lenses.

[0003] Among them, the glass softening process requires the use of a glass softening furnace. Traditional glass softening furnaces are generally composed of a heating furnace with an opening at the bottom and a vertical telescopic rod. The telescopic rod is extended and retracted to drive the glass segment in and out of the heating furnace to realize the heating and softening process of the glass segment. In order to improve the processing efficiency of traditional glass softening furnaces, the applicant has developed a multi-station optical glass precision energy-saving softening furnace disclosed in ZL202321577681.9; the equipment is equipped with multiple softening furnaces evenly distributed along the arc, so that the multi-station softening furnaces can perform glass softening operations in sequence, thereby improving the overall processing efficiency. However, when using this type of equipment, it is necessary to load and unload glass segments at multiple stations, and the operation process is more cumbersome.

[0004] Therefore, the existing multi-station glass softening furnace has the problem that the loading and unloading operations are relatively troublesome. Utility Model Content

[0027] The support bracket 11 is hollow; one side of the support seat 10 is connected to an air inlet pipe 13 and an air outlet pipe 14, and the support seat 10 is provided with an air inlet duct 15 and an air outlet duct 16 respectively connected to the two ends of the bottom of the support bracket 11; the rotating shaft 3 is connected to a cooling air distributor 17, and a corrugated hose 18 passing through the mounting tube 4 is connected between the cooling air distributor 17 and the air inlet pipe 13 and the air outlet pipe 14 on each support seat 10, and the top of the cooling air distributor 17 is connected to the air intake manifold through a rotary joint 19; the electric slip ring 12 is connected to the top of the cooling air distributor 17; the top of the support bracket 11 is provided with a horizontal section, and the top surface of the horizontal section is provided with a U-shaped placement groove 21; the lower mounting plate 6 corresponds to each extension A controller 22 is connected to one side of the retracting electric cylinder 9, and each controller 22 is electrically connected to the electric slip ring 12 through an electric wire; each controller 22 is electrically connected to its corresponding telescopic electric cylinder 9 and the heating furnace 7 through an electric wire; a mounting plate 23 is provided between the top surface of the heating furnace 7 and the upper mounting plate 5, and the edge of the mounting plate 23 is protruding and arranged on the outside of the heating furnace 7; both sides of the top of the heating furnace 7 are provided with outwardly extending protrusions 24, and a No. 1 screw 25 is connected between the protrusion 24 and the mounting plate 23; a thermal insulation pad 26 is sandwiched between the two diagonal positions of the mounting plate 23 and the upper mounting plate 5, and a No. 2 screw 27 is connected between the other two diagonal positions of the mounting plate 23 and the upper mounting plate 5.

[0028] Working principle: During operation, a worker or a manipulator is placed at the glass segment loading and unloading station on one side of the base 1; when the driving motor 2 on the base 1 drives the mounting cylinder 4 to rotate through the rotating shaft 3, when the heating furnace 7 on the upper mounting plate 5 rotates to the glass segment loading and unloading station, the telescopic electric cylinder 9 on the lower mounting plate 6 corresponding to the bottom of the heating furnace 7 drives the supporting seat 10 and the supporting frame 11 to move downward, so that the horizontal section of the top of the supporting frame 11 is located below the heating furnace 7; then, the worker or manipulator can take the glass segment raw material and place it on the supporting frame 1 1 is placed in the U-shaped placement groove 21 on the top surface of the top horizontal section (the placement groove 21 can stably place a cylindrical glass segment horizontally, with high placement stability); then, the telescopic electric cylinder 9 drives the supporting seat 10, the supporting bracket 11 and the glass segment raw material to rise until the supporting seat 10 and the supporting bracket 11 extend the glass segment raw material into the heating furnace 7 through the discharge port 8; finally, the driving motor 2 drives the installation cylinder 4 to rotate via the rotating shaft 3, moving the heating furnace 7 in this position to the next station. At the same time, the heating furnace 7 in the previous station moves to this station for the glass segment loading operation.

[0029] When the heating furnace 7 that has completed the glass segment loading operation rotates back to the glass segment loading and unloading station, the glass segment on the support frame 11 has been heated and softened. At this time, the telescopic electric cylinder 9 drives the support seat 10, the support frame 11 and the softened glass segment to move downward to the bottom of the heating furnace 7. The staff uses tools to clamp the softened glass segment and then puts the glass segment raw material back in, thereby realizing the single-station glass segment loading and unloading operation.

[0030] When the rotating shaft 3 drives the mounting cylinder 4 to rotate, the cooling air distributor 17 connected to the mounting cylinder 4 rotates synchronously with the mounting cylinder 4. The top of the cooling air distributor 17 is connected to the air intake manifold and the air outlet manifold (the air intake manifold and the air outlet manifold are not shown in the accompanying drawings) through a rotating joint 19, so that the air intake manifold will not have entanglement problems; the cooling air distributor 17 corresponds to each air intake pipe 13 and air outlet pipe 14 on each supporting seat 10. A corrugated hose 18 is connected between the air intake pipe 13 and the air outlet pipe 14. The corrugated hose 18 can deform and adapt when the supporting seat 10 is raised and lowered, thereby ensuring a stable supply of cooling air. The cooling air enters the air inlet duct 15 in the support seat 10 through the air inlet main pipe, the cooling air distributor 17, the corrugated hose 18 and the air inlet pipe 13, and passes through the interior of the hollow support frame 11 and then is discharged and refluxed from the air outlet main pipe through the air outlet duct 16, the air outlet pipe 14, the corrugated hose 18 and the cooling air distributor 17; after passing through the horizontal section at the top of the support frame 11, the cooling air can cool the part to prevent the part from being overheated and adhering to the softened glass section.

[0031] An electric slip ring 12 is connected to the top of the cooling air distributor 17, corresponding to the area below the rotary joint 19. This allows the rotor and stator on the slip ring 12 to rotate relative to each other when the cooling air distributor 17 drives the slip ring 12. This prevents entanglement of the wires (not shown) connected to the rotor or stator, ensuring power supply stability. Each telescopic cylinder 9 is equipped with a controller 22 connected to the lower mounting plate 6. This controller 22 controls the telescopic movement of the telescopic cylinder 9 and maintains the heating temperature of the heating furnace 7, ensuring optimal glass softening.

[0032] A mounting plate 23 is provided on the top of the heating furnace 7, and the mounting plate 23 and the protrusions 24 on both sides of the top of the heating furnace 7 are fixed by No. 1 screws 25. No. 2 screws 27 are connected between the two top corners of the mounting plate 23 protruding outside the heating furnace 7 and the upper mounting plate 5. At the same time, a thermal insulation pad 26 is sandwiched between the other two top corners of the mounting plate 23 and the upper mounting plate 5, so that the heating furnace 7 is suspended as much as possible in an insulated state to ensure a stable connection between the heating furnace 7 and the upper mounting plate 5.
