Description

TECHNICAL FIELD

[0001] The present application relates to the field of liquid crystal display bonding equipment, in particular to a COG and COF pre-pressing universal production equipment and a pre-pressing universal method. BACKGROUND

[0002] LCD (English full name: Liquid Crystal Display, Chinese name: liquid crystal display) is a display screen that uses liquid crystal to control light transmittance technology to realize color display, and has many advantages such as small size, thin thickness, light weight, etc. Therefore, it is very popular on the market. LCD needs to use IC chips during production. The combination of IC chips and LCD usually has two ways, one is to directly bond IC chips on LCD, and the other is to first package IC on FPC (English full name: Flexible Printed Circuit, Chinese name: flexible circuit board), and then bond FPC with LCD. The former combination is COG (chip on glass) bonding, and the latter combination is COF (chip on flex) bonding. COG bonding and COF bonding usually have three steps of ACF attachment, pre-pressing and main pressing, and the pre-pressing step is mainly to improve the connection accuracy of LCD and IC or LCD and FPC.

[0003] At present, the pre-pressing machines on the market are usually designed for a certain bonding method, such as COG pre-pressing machine which can only pre-press IC and LCD, and cannot pre-press FPC and LCD. COF pre-pressing machine can only pre-press FPC and LCD, and cannot pre-press IC and LCD. Therefore, when pre-pressing in these two different ways, two pre-pressing devices need to be purchased, which not only increases the production cost, but also occupies a large area.

[0004] The utility model patent number CN211061805U discloses a kind of semi-automatic COG pre-pressing machine, the upper surface of cabinet is provided with alignment fixture, the upper of alignment fixture is provided with pre-pressing mechanism, alignment fixture and pre-pressing mechanism are provided with chip feeding mechanism between, the both sides of chip feeding mechanism are provided with visual mechanism, control system is arranged in the inside of cabinet, chip feeding mechanism, alignment fixture, pre-pressing mechanism, visual mechanism are respectively connected to control system, pre-pressing mechanism and visual mechanism are fixed on the upper front end of cabinet, alignment fixture is fixed on the upper surface of cabinet, chip feeding mechanism is fixed on the both sides in the inside of cabinet. The pre-pressing machine is mainly used for the pre-pressing of IC chip and LCD, and cannot realize the pre-pressing function between FPC and LCD.

The full-automatic pre-pressing machine is used for pre-pressing between FPC and LCD, and has certain design defects if used for pre-pressing between IC and LCD, and cannot meet the production requirements.

[0006] For the related technology in the above, there is a problem of incompatibility of the pre-pressing machine with multiple pre-pressing processes. SUMMARY

The universal production equipment for COG and COF pre-compression according to claim 5, characterized in that, The bottom of the feeding box (52) and the recycling box (53) are provided with baffles (56) that can slide to both sides, so that the tray (55) can enter and exit from the bottom of the feeding box (52) or the recycling box (53).

7. The universal production equipment for COG and COF pre-compression according to claim 4, characterized in that, The workpiece loading mechanism (60) includes a loading platform (61) that can move in three dimensions, a support plate (62) connected to the side of the loading platform (61), and a vacuum adsorption zone (63) with an adjustable adsorption area set on the loading platform (61).

8. The universal production equipment for COG and COF pre-compression according to claim 4, characterized in that, The feeding mechanism (50) and the workpiece loading mechanism (60) are provided with two identical sets.

9. The universal production equipment for COG and COF pre-compression according to claim 1, characterized in that, The general-purpose material handling mechanism (20), the pre-compression back support (30), and the pre-compression alignment mechanism (40) are all provided with two identical sets.

10. A general method for preloading, characterized in that, The COG and COF pre-compression general production equipment as described in any one of claims 1-9, wherein the general pre-compression method comprises: S1. Provide production equipment that can universally feed COG and COF products. The COG product includes a first chip, and the COF product includes an FPC flexible board with a second chip. The production equipment includes a rotatable adsorption pre-pressing head (41), a universal material handling mechanism (20), and a pre-pressing back support (30) with a groove (31). The linkage (21) of the universal material handling mechanism (20) is provided with a suction nozzle (22) that can flip and pick up the COG product and move it to the bottom of the adsorption pre-pressing head (41). The linkage (21) is also provided with a suction cup (23) that can pick up the COF product and move it to the pre-pressing back support (30). The groove (31) is used to accommodate the second chip. The pre-pressing back support (30) forms a pre-pressing support (32) on one side of the groove (31). The side of the pre-pressing support (32) forms several optical path detection holes (33). S2. Use the adsorption-type pre-press head (41) to adsorb the back side of the pre-press position of the first chip or the FPC flexible board; S3. The pre-press position of the first chip or the FPC flexible board is detected by the optical path detection hole (33) and the adsorption posture of the adsorption type pre-press head (41) is detected. The adsorption type pre-press head (41) is rotated and adjusted to perform pre-press correction for optical path alignment. S4. Load the workpiece so that the back side of the pre-press position of the workpiece is located on the pre-press support (32) of the pre-press back support (30), and the pre-press position of the workpiece is located below the pre-press position of the first chip or the FPC flexible board. S5. Press down the adsorption-type pre-press head (41) so that either the first chip or the pre-press position of the FPC flexible board can be engaged with the pre-press position of the workpiece.
