Description

Laser welding robot

Technical Field

The utility model relates to a laser welding robot.

Background

Laser welding robots generally use a semiconductor laser as a welding heat source, and are widely used for welding camera parts of electronic devices such as mobile phones and notebook computers.

Laser welding equipment such as laser welding robot among the prior art commonality is relatively poor, and welding range is little, and the pivot rotation precision is low, pushes down the mechanism depth of parallelism not high enough, and equipment integration is low. Have failed to meet the ever-increasing production needs.

SUMMERY OF THE UTILITY MODEL

The utility model provides a laser welding robot, its purpose aims at overcoming the above-mentioned not enough that prior art exists, effectively improves the equipment commonality, and increase welding range improves pivot rotation precision and pushes down the parallel degree of mechanism, improve equipment integration level, reduction in production cost.

The technical solution of the utility model is as follows: laser welding robot, its structure is including installing two servo main shafts in the frame, every servo main shaft lower extreme is connected with the servo motor in the frame of below, the tool is established to the upper end, press the mechanism respectively to establish in every servo main shaft top, establish the button in the frame of servo main shaft one side, establish the laser welder head in the frame of opposite side, the laser welder head is installed on the Z module, the Z module is installed on the Y module, the Y module is installed on the X module, the X module is installed in the frame along two linear bearing side, the overhead laser head angle adjustment mechanism that still is equipped with of laser welder, laser generator is equipped with to the frame inboard of servo main shaft below, water chiller and pneumatic controller, the electricity cabinet is equipped with to the frame inboard of.

Preferably, the pressing mechanism comprises two guide shafts and four guide shafts which are arranged on the machine frame on two sides of the servo main shaft, a hydraulic buffer is arranged between the guide shafts, the top ends of the guide shafts are connected with the mounting plate through linear bearings, a pressing cylinder is arranged in the center of the mounting plate, the movable end of the pressing cylinder penetrates through the mounting plate and is connected with the pressing shaft, and the pressing shaft is located above a jig on the upper end of the servo main shaft.

The utility model has the advantages that: structural design is reasonable, XYZ three-dimensional module drive laser head, servo spindle drive product, and more complicated welding curve is realized to both cooperations. Two station designs can make full use of laser welding module more, reduces the use cost of equipment. The pressing mechanism adopts four-column guiding and adopts hydraulic buffering, so that the parallelism of the pressing shaft is higher, and the pressing is more stable. The water cooler and the laser generator are integrated in the rack, so that the overall dimension of the equipment is more compact, and the floor area of the equipment is greatly reduced. Effectively improve equipment commonality, increased welding range, improved pivot rotation accuracy, reduced manufacturing cost.
