Description

Technical Field

[0001] The utility model mainly relates to the technical field of LCD processing, and in particular to a feeding device for an LCD mounter. Background Art

[0002] During the preparation of the LCD display module, the glass substrate needs to be precisely mounted on the liquid crystal box and assembled together with the backlight source to form a complete module. This process requires a high degree of precision and reliability and needs to be achieved through a placement machine.

[0003] When mounting chips, the pick-up mechanism needs to grab the glass substrate and put it on the chip mounter. In the prior art, a robotic arm is usually used in conjunction with an electric vacuum suction cup to achieve this. However, the cost of the robotic arm is relatively high, and the movement stroke is relatively long, and the loading speed is relatively slow, which affects production efficiency.

[0026] The first telescopic cylinder 4 and the second telescopic cylinder 5 are respectively installed on both sides of the through slot 201. The telescopic ends of the two telescopic cylinders are relatively distributed and are respectively fixedly connected with a push plate 6 and a receiving plate 7. The push plate 6 is slidably matched with the through slot 201, and the top of the receiving plate 7 is located at the same horizontal plane as the bottom of the through slot 201.

[0027] A loading trough 101 is provided on the loading platform 1, and the loading trough 101 is close to the receiving plate 7, and a placement machine body 8 is arranged below, and a support frame 9 is arranged above.
