Linear module, also known as linear module, is a motion unit that modularizes the linear motion platform, and integrates the guide rail system and transmission system into one unit. The interior of the linear module is wrapped with aluminum profile, the linear guide rail is used as the internal linear support, and the ball screw and link motor are used as the power source for output. This system integration greatly facilitates the design and selection of engineers, and makes the assembly of equipment simpler and modular. There are several common mechanical transmission systems on the market: lead screw, synchronous belt, gear rack; The drive of these transmission systems is realized by rotating motor / reducer.

Type of linear module

At present, the widely used linear modules can be divided into two types: synchronous belt type and ball screw type.

orking principle of synchronous belt type is: the belt is installed on the transmission shaft on both sides of the linear module, which is used as the power input shaft, and a sliding block for increasing equipment workpieces is fixed on the belt. When there is input, the slider moves by driving the belt.

Ball screw is an ideal product that transforms rotary motion into linear motion or linear motion into rotary motion. Ball screw consists of screw, nut and ball. Its function is to convert rotary motion into linear motion, which is the further extension and development of ball screw. The significance of this development is to change the bearing from rolling action to sliding action. Due to its small friction resistance, ball screw is widely used in various industrial equipment and precision instruments. It can realize high-precision linear motion under high load

Selection of linear module

If the force is large, the stroke is short, and the accuracy requirements are relatively high, customers can choose the screw straight-line module;

If the force is general, the stroke is long, and the accuracy requirements are not high, customers can choose the synchronous belt linear module.

Composition of linear module:

Synchronous belt linear module: it is composed of belt, linear guide rail, aluminum alloy profile, coupling, motor, photoelectric switch, etc.

Ball screw linear module: it is composed of ball screw, linear guide rail, aluminum alloy profile, ball screw support seat, coupling, motor, photoelectric switch, etc.

Closed type: the force bearing part of the linear module is mainly concentrated in the external data to close the transmission part

Open type: the force bearing part of the linear module is mainly concentrated at the middle and lower parts and both sides, and the transmission part is exposed.

Uniaxial linear module: mainly used for PCB substrate inkjet equipment, circuit board surface cleaning equipment, IC printing equipment, bar code scanning equipment, filling equipment, etc.

Multi axis linear module: it is mainly used for circuit board transfer equipment, active soldering equipment, locking screw equipment, small part taking and placing equipment, etc.
