[0071] In the second embodiment, the present invention provides an operation method of a rubber frame jig for assembling a vehicle backlight source to avoid scraping of the rubber frame buckle, and the jig in the first embodiment is used. The operation method includes the following steps:

[0072] The first step is to clean the fixture before operation, connect the fixture to the positive pressure air pipe, turn on the power switch of the fixture, check that the air pressure value of the fixture pressure gauge is between 0.6-0.7Mpa, and the downward pressure of the fixture is between 0.6-0.7Mpa;

[0073] The second step is to press the pressurization switch of the fixture with both hands at the same time, and the fixture will start to pressurize. The product pressurization time is 3 seconds. The fixture pressure gauge and pressurization time are not allowed to be adjusted without permission during the operation.

[0074] The third step is to take the assembled film-attached product and place it in the limiting area formed by the fixture positioning block 9. When the backlight is placed, the buckle position must be correctly limited and placed, and the FPC is inserted into the avoidance groove to the right;

[0075] Step 4: After the product is fixed and placed, use a sticky stick to tear off the protective film surface of the backlight source body 12 from the upper right corner, and place it on a clean surface on the table after tearing it off; wait for the plastic frame body 11 to be assembled and then cover the light-emitting area; after the protective film is torn off, check 100% whether the light control film in the upper left corner has a convex platform;

[0076] Step 5: Take the semi-finished plastic frame body 11, hold the middle position of the two short sides of the plastic frame body 11, check that the foam glue 1101 is not lost, and place the plastic frame body 11 with the front side facing up and the long and wide sides facing forward in a flat manner into the restricted area formed by the positioning blocks 9;

[0077] Step 6. After the rubber frame body 11 and the backlight source body 12 are limited, press the two start buttons on the side of the jig with both hands at the same time. The output end of the downward pressure cylinder 4 of the jig drives the connecting block 401, the sliding guide plate 6 and the upper mold 7 to be pressed down synchronously. During the pressing process, the rubber frame body 11 and the backlight source body 12 are automatically assembled. The pressing time is 3 seconds. At the same time, the foam glue 1101 and the CG double-sided tape are pressurized.

[0078] Step 7: After the assembly of the rubber frame body 11 and the backlight source body 12 is completed, the output of the jig lifting cylinder 13 drives the lower mold 1301 upward to lift the product, thus completing the assembly of the rubber frame body 11 and the backlight source body 12; take the reserved film surface protective film to cover the light-emitting area of ​​the backlight source body 12;

[0079] Step 8. Finally, take the product out of the fixture and check the assembly effect of the buckles of the plastic frame body 11. The 12 buckles on the long side and the 6 buckles on the short side of the product must all be snapped into place.
