Description

Technical Field

[0001] The invention relates to the technical field of laminating machine equipment, in particular to ultra-high pressure lifting and lowering positioning precision equipment for laminating machines. Background Art

[0002] In the operation of chip component lamination machine, the alignment mechanism plays a core role. Since the upper process of lamination is printing, each dielectric film will produce different degrees of displacement during the printing process. The alignment mechanism is a device to compensate for the displacement.

[0003] There is a laminating machine on the market, which adopts an XYθ three-axis linkage alignment mechanism. If the stroke is too large during the action, the corresponding displacement error will also become larger. Moreover, when the θ axis moves, the two plates contact each other and rotate around the center frictionally. The longer the working time, the greater the friction, the greater the displacement error. Before being pressed, the commonly used alignment mechanism is not completely fitted in the vertical and horizontal directions, and there is a certain gap. These gaps will be completely fitted under high pressure. In this way, there will be a certain amount of translation when the upper mold and the lower mold are fitted during the pressure process, so that the displacement error of the product will also increase, the uniformity of the product pressure is unstable, and the risk of damage to the product due to uneven pressure will increase.

The second slide rail is arranged vertically with the first slide rail, and a second slide seat is installed on the second slide rail, and the lower suction cup mounting plate is installed on the second slide seat; The high-precision compensation actuator includes four compensation servo motors, which are evenly arranged on the upper part of four square plates surrounding the alignment compensation working platform, and the output ends of the four compensation servo motors are all arranged in the clockwise or counterclockwise direction; the ball screw of the compensation servo motor is parallel to the first guide rail and connected to the first slide seat; The lower suction cup mounting plate is a symmetrical plate body, and a second square hole is provided in the center; A central force-adding top block with a square cross section is installed in the middle of the upper surface of the oil cylinder connecting movable plate, and the size of the central force-adding top block is matched with the first square hole and the second square hole.

[0006] Furthermore, the lifting slider assemblies are provided with six, and the six lifting slider assemblies are respectively installed in groups of three on both sides of the oil cylinder connecting the movable plate, and the upper cylinders are provided with four upper cylinders, and the four upper cylinders are respectively installed in groups of two on the outer sides of the two mounting plates.

[0010] Furthermore, the four groups of compensation servo motors and the lifting cylinders are controlled by a system controller.

[0011] Beneficial effects of the present invention: The present invention adopts a four-axis linkage alignment mechanism to concentrate the alignment compensation action on a small platform with a very small stroke, which effectively reduces the displacement error caused by excessive movement stroke, and solves the problem of displacement error caused by too large stroke of the alignment mechanism used in the past; when the present invention is working, the lower suction cup installed on the lower suction cup mounting plate is non-contact with the central force-adding top block, which also solves the problem that the greater the friction, the greater the displacement error. There is no gap before and after compression, which effectively reduces the displacement error of the product during the compression process, ensures that the product is evenly compressed, reduces the risk of damage to the product due to uneven compression, and avoids the risk of friction damage to the equipment, effectively extending the working life of the equipment; after the precise alignment compensation of the present invention, the upper mold and the lower mold are precisely fitted during the compression process, and are more accurate during operation, which effectively reduces product damage due to uneven compression and makes the product more evenly compressed.
