Problems solved by technology

However, the linear motor with this construction method is not only very complicated in structure, but also very complicated to adjust.
In addition, there are flow losses due to the long cooling air delivery lines via the delivery ducts

Embodiment Construction

[0014] FIG. 1 shows an embodiment of an automatic assembly machine 1 in a schematic top view. The substrates 2 to be assembled are transported by means of a conveyor belt 3 to an assembly station, where they are equipped with electrical components 4 (see FIG. 2A ), and then taken away from said assembly station. The conveyor belt 3 is arranged on a chassis 5 of the automatic assembly machine 1 . The chassis 5 includes a frame 6 spanning the conveyor belt 3 like a bridge.

[0015] The assembly process is carried out by an assembly head 7 which is movable in a movement direction X along a positioning arm 9 driven by a linear motor 8 (not shown in FIG. 1 ). The positioning arm 9 itself is mounted on the bridge support 6 and can also move in a moving direction Y driven by a linear motor (not shown in FIG. 1 ). In this case, both the assembly head 7 and the positioning arm 9 can be regarded as movable parts that can move relative to the chassis 5 driven by the linear motor.

Abstract

The invention provides an automatic assembly machine (1) which assembles electric parts (4) for a base (2). The invention comprises an underframe (5), a linear motor (8) and movable parts (7, 9); the movable parts can move corresponding to the underframe (5) under the driving of the linear motor (8); wherein, the movable parts (7, 9) have the installation surface (16) of an initial part (14) which can fix the linear motor (8); wherein, a fluid passage (20) is formed between the installation surface (16) and the initial part (14); the automatic assembly machine also comprises a blowing device (21) which is fixed on the movable parts (7, 9) and can deliver air through the fluid passage when in use.

Description

technical field [0001] The invention relates to an automatic assembly machine for equipping substrates with electrical components, having a moving part driven by a linear motor and a blower device for cooling said linear motor. Background technique [0002] The publication DE-19842384-A1 discloses a linear guide device which has a guide support on which a longitudinally displaceable guide carriage is supported. The drive of the guide carriage is an electric motor which has a motor primary part arranged on the guide carriage and a motor secondary part arranged in the guide support. Ventilation slots are built into the guide car to dissipate the heat lost by the electric motor. However, the disadvantage of this device is that its ability to dissipate the lost heat is extremely limited. Therefore, when the motor power used is relatively high, and the installation space is relatively narrow, it will lead to heat accumulation, which leads to the occurrence of undesired heat in t...
