Abstract
Description
Technical Field
[0001] This utility model relates to the field of linear motors, and in particular to a linear motor linkage mechanism. Background Technology
[0002] In some material handling scenarios, or in situations requiring two motion axes to move in opposite directions simultaneously, it is necessary to drive two sets of modules to move synchronously in opposite directions. Currently, most existing technologies use two sets of drive mechanisms (usually two sets of linear motors) to drive the two sets of modules to move synchronously in opposite directions. However, this existing method of using two sets of drive mechanisms to achieve reverse motion simultaneously requires that each set of drive mechanisms be controlled independently, and each requires a power source, position sensor, and driver, etc., which is difficult to control, has a complex structure, and is costly.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.
[0020] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0021] Please refer to Figures 1-3 The linear motor linkage mechanism of this utility model embodiment includes a base, a linear motor, an active module, a driven module, and a linkage module.
[0022] The linear motor and linkage module are mounted on the base, and the active module is mounted on the linear motor. The linkage module is connected to both the active and driven modules, and the active module drives the driven module through the linkage module. Loads are installed on both the active and driven modules.
[0023] In one implementation, the linkage module consists of a steel belt and several guide rollers, with the steel belt connecting the driving module and the driven module. Preferably, there are four sets of guide rollers, which are correspondingly located at the four corners of the base, and the steel belt is fitted onto the four sets of guide rollers.
[0024] In one implementation, the active module and the driven module are located on the front and rear sides of the base respectively, so as to realize the synchronous reverse movement of the active module and the driven module.
[0025] The driven module and the driven module are equipped with steel belt fixing components, which connect the driven module to the steel belt. The driven module is equipped with steel belt tensioning components. The driven module connects to both ends of the steel belt through the steel belt tensioning components and tightens the steel belt, so that the steel belt is fitted onto several guide rollers.
[0026] In one implementation, the base is provided with several linear guides for guiding the movement of the active module and the driven module, respectively. The linear guides improve the stability of the movement of the active module and the driven module.
[0027] As one implementation method, the active module is equipped with a position sensor. The position sensor can be a linear encoder position sensor, which offers high accuracy.
[0028] The steel strip of this invention has no flexibility or stretching, thus ensuring the operating accuracy of the driven module.
[0029] This invention uses an active module to drive the driven module to move simultaneously, resulting in low cost, simple control, and high positioning accuracy of the driven module.
