Description

Technical Field

[0001] This invention relates to the field of automotive lighting manufacturing technology, specifically to a cooling furnace after automotive lighting annealing. Background Technology

[0002] After plastic welding, automotive lights generate welding stress, which must be relieved by annealing. After annealing, the lights typically reach a stable temperature of over 70°C. Traditional processes cannot cool the lights quickly enough, leading to unstable leakage values ​​during airtightness testing (temperature has a significant impact on air pressure and the accuracy of airtightness leakage). This results in misjudgments in airtightness testing, affecting production efficiency and product quality. The appropriate temperature for airtightness testing must be less than room temperature plus 10°C. Since the temperature of automotive lights after annealing is generally 70°C, a cooling furnace is required to cool the lights after annealing.

[0003] However, the cooling devices currently used for headlight annealing require a significant amount of time to operate when the headlights are in and out, resulting in inconsistent operation and unstable annealing effects. Summary of the Invention

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1.

[0028] 2. By setting up safety light curtains, sliding holes, electric slide rails, sliding door panels, blocking plates, heat insulation plates, and limit bars, the sliding door panels can be moved and opened and closed quickly by using the safety light curtains to sense the entry and exit of the vehicle lights. This, combined with the use of supports and vehicle light placement trays, makes the process even more efficient.

[0029] 3. By setting up rotating gears, rotating chains, positioning blocks, triangular rods, mounting holes, number marker blocks, cooling baskets, and docking holes, the cooling baskets are connected through the positioning blocks and triangular rods. When the rotating chain rotates, it can drive the vehicle lights placed on the cooling baskets to rotate together, performing a cyclical cooling operation.

[0030] 4. By setting up a cooling fan, drive motor, drive gear disk, first driven gear disk, first transmission chain, second driven gear disk and second transmission chain, the drive motor drives the drive gear disk to rotate, then drives the first driven gear disk to rotate, and finally drives the second driven gear disk to rotate, thereby driving all the rotating gears to rotate, which facilitates the stable and smooth operation of the cooling basket.

[0031] In summary, by setting electric telescopic rods at the front and rear ends, the support rods move, the safety light curtain senses, the sliding door panel moves, and the headlight placement tray moves, making it convenient to put in and take out the headlight placement tray.

[0058] A rotating cooling assembly 8 is installed on the top of the cooling furnace frame 1;

[0059] The rotating cooling assembly 8 includes a top cover 801, a cooling fan 802, a drive motor 803, a drive gear disk 804, a first driven gear disk 805, a first transmission chain 806, a second driven gear disk 807, and a second transmission chain 808.

One gear meshes with the first transmission chain 806, and the other gear meshes with the second transmission chain 808, which facilitates driving the top and bottom rotating gears 701.

[0061] The working principle and usage process of this invention are as follows: When placing the vehicle lamp, first, the snap-fit ​​long block 515 of the vehicle lamp placement plate 512 is snapped into the snap-fit ​​groove 506 inside the support rod 505. Then, the annealed vehicle lamp is placed in the placement groove 513 at the top of the vehicle lamp placement plate 512. The connecting long plate 509 is moved by the electric telescopic rod 511, which in turn drives the snap-fit ​​block 503, the support rod 505 and the vehicle lamp placement plate 512 to move towards the connecting opening 4. When it moves to the position of the safety light curtain 601, the safety light curtain 601 senses the vehicle lamp placement plate 512, and thus transmits the signal to the control terminal of the electric slide rail 603, which controls the electric slide rail 603 to drive the sliding door panel 604 to move to both sides of the device and open the connecting opening 4.

[0062] After the connecting opening 4 is opened, the drive motor 803 drives the drive gear disk 804 to rotate, which in turn drives the first driven gear disk 805, the first transmission chain 806, and the second transmission chain 808 to rotate, thereby driving the rotating gear 701, the rotating chain 702, and the cooling basket 707 to rotate, so that the cooling basket 707 moves to the position of the connecting opening 4.

[0063] After the cooling basket 707 moves to the position of the connecting opening 4, the electric telescopic rod 511 pushes the support rod 505 and the headlight placement plate 512 to the top of the cooling basket 707, so that the snap-fit ​​long block 515 is vertically aligned with the docking hole 708. Then the cooling basket 707 continues to move upward. Since the snap-fit ​​long block 515 does not move, the cooling basket 707 moves upward, so that the docking hole 708 snaps with the snap-fit ​​long block 515. Then the electric telescopic rod 511 pulls the support rod 505 out of the top of the cooling basket 707. As the support rod 505 is pulled out, the support long block 514 on the outside of the snap-fit ​​long block 515 fits against the top of the cooling basket 707. As the support rod 505 is pulled out, the safety light curtain 601 senses it, and the electric slide rail 603 drives the sliding door panel 604 to move towards the middle to close the connecting opening 4.

[0064] When removing the cooled headlight, the electric telescopic rod 511 at the rear of the device pushes the support rod 505 to move to the safety light curtain 601, causing the electric slide rail 603 at the rear of the device to move the sliding door panel 604 to both sides and open. Then, observe the moving triangular rod 704, find the required number marker block 706, and when it moves to the position of the connecting opening 4, move the support rod 505 to insert into the top position of the snap-fit ​​long block 515. Then, the cooling basket 707 moves downward. At this time, the snap-fit ​​long block 515 at the bottom of the headlight placement tray 512 separates from the cooling basket 707. Then, the electric telescopic rod 511 drives the headlight placement tray 512 to move and remove it. Finally, the headlight placement tray 512 can be slid out from the top of the support rod 505.

[0065] The headlight placement tray 512 is placed on top of the cooling basket 707 by engaging the support rod 505 with the bottom of the snap-fit ​​long block 515 at the bottom of the headlight placement tray 512, and the headlight placement tray 512 is removed from the top of the cooling basket 707 by engaging the support rod 505 with the top of the snap-fit ​​long block 515 at the bottom of the headlight placement tray 512. This facilitates the entry and exit of the headlights and automatically opens and closes the connection opening 4, making the operation smoother.

[0066] The drive motor 803 drives the drive gear disk 804, the first driven gear disk 805, and the second driven gear disk 807 to rotate, which in turn drives the rotating gear 701 and the cooling basket 707 to rotate, causing the cooling basket 707 to rotate in a circular motion inside the device. The cooling fan 802 exhausts air upwards, resulting in good cooling effect and helping to cool the annealed headlights.

[0067] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
