At present to the design of X, y axle motor module platform, be two parallel X axle modules mostly and erect the y axle module on two X axle modules, the stroke of y axle module is greater than the width of X axle (i.e. the stroke of y axle module extends to two in the X axle module one keep away from outside another one side), when the y axle movable plate on the y axle module moves to one side that surpasss X axle module width direction, the focus outwards squints, whole X, y axle motor module platform operation is unstable, the reliability is poor. And the structure of present motor module is more, and the installation is inconvenient.
In view of the above problems, the present inventors have studied and researched to provide the following embodiments to solve the above problems.
Referring to fig. 1, an embodiment of the present invention provides a dual-axis linear motor module platform 10, including: an x-axis module 100 and a y-axis module 200 disposed vertically above the x-axis module 100.
The x-axis module 100 includes an x-axis moving plate 101. The x-axis moving plate 101 is fixedly connected with the bottom of the y-axis module 200.
Alternatively, the x-axis moving plate 101 may be fixedly connected to the bottom of the y-axis module 200 by screws, for example, screw holes are formed in the bottoms of the x-axis moving plate 101 and the y-axis module 200, and the screws pass through the screw holes in the x-axis moving plate 101 and the screw holes in the bottom of the y-axis module 200, so as to fixedly connect the bottoms of the x-axis moving plate 101 and the y-axis module 200. It is understood that in other embodiments, the fixed connection between the x-axis moving plate 101 and the bottom of the y-axis module 200 may also be a snap-fit or a snap-fit. The present application is not limited thereto.
The y-axis module 200 includes a y-axis moving plate 201. The moving range of the y-axis moving plate 201 is a range defined by two sides of the x-axis module in the width direction. In the embodiment of the present application, one x-axis module 100 can carry one y-axis module 200, which simplifies the structure compared to the x-axis and y-axis motor module platform in the prior art that includes two parallel x-axis modules and two y-axis modules erected on the two x-axis modules. In addition, in the current design of the x-axis and y-axis motor module platform, the stroke of the y-axis module 200 is larger than the width of the x-axis, and when the y-axis moving plate on the y-axis module 200 moves to a side beyond the width direction of the x-axis module 100, the center of gravity will shift outward. In the implementation of the present application, by increasing the width of the x-axis module 100, it is further ensured that the stroke of the y-axis moving plate 201 is less than or equal to the width of the x-axis module 100, that is, the moving range of the y-axis moving plate 201 is within the range defined by the two sides of the x-axis module 100 in the width direction, that is, the moving boundary of the y-axis moving plate 201 does not exceed any one of the two sides of the x-axis module 100 in the width direction.
Referring to fig. 1 and 2, the structure of the x-axis module 100 will be described in detail, and for convenience of describing the internal structure of the x-axis module 100, the x-axis module 100 shown in fig. 2 does not include the x-axis moving plate 101.

The x-axis linear motor 102, the first x-axis slide rail 103, and the second x-axis slide rail 104 are disposed below the x-axis moving plate 101. The x-axis linear motor 102, the first x-axis slide rail 103 and the second x-axis slide rail 104 are arranged in parallel.
In one embodiment, the x-axis linear motor 102 is located right below the x-axis moving plate 101, and the first x-axis slide rail 103 and the second x-axis slide rail 104 are located at both sides of the x-axis linear motor 102. In order to ensure the stability of the x-axis module 100, the distance between the first x-axis slide rail 103 and the x-axis linear motor 102 is equal to the distance between the second x-axis slide rail 104 and the x-axis linear motor 102. It can be understood that, in the present application, the width of the x-axis module 100 is increased by increasing the distance between the first x-axis slide rail 103 and the x-axis linear motor 102, and/or the width of the x-axis module 100 is increased by increasing the distance between the second x-axis slide rail 104 and the x-axis linear motor 102, so that one y-axis module 200 can be carried by one x-axis module 100. Of course, the setting of the width of the specific x-axis module 100 may be determined according to actual requirements, that is, the distance between the first x-axis slide rail 103 and the x-axis linear motor 102 and/or the distance between the second x-axis slide rail 104 and the x-axis linear motor 102 may be set according to actual requirements.
Of course, in other embodiments, the first x-axis slide rail 103 may be located right below the x-axis moving plate 101, and the second x-axis slide rail 104 and the x-axis linear motor 102 may be located at two sides of the first x-axis slide rail 103. The orientation of the first x-axis slide 103, the second x-axis slide 104, and the x-axis linear motor 102 is not limited in this application.

It is understood that in other embodiments, the number of x-axis sliders may be 6, 10. Of course, the number of the x-axis sliding blocks can be set according to actual requirements, and the application is not limited.
It should be noted that the linear motor is a transmission device that directly converts electric energy into mechanical energy for linear motion without any intermediate conversion mechanism. In the present application, the x-axis linear motor 102 is connected to an external controller. The external controller is used for driving the x-axis linear motor 102, and when the x-axis linear motor 102 is driven, the x-axis linear motor 102 can generate linear motion, so as to drive the x-axis moving plate 101 connected with the x-axis linear motor 102 to slide on the first x-axis slide rail 103 and the second x-axis slide rail 104.

The x-axis mover 1021 is movable on the x-axis U-shaped magnetic circuit 1022, and the x-axis mover 1021 is located at the center of the x-axis U-shaped magnetic circuit 1022. In the present application, the x-axis rotor 1021 is in the shape of an "I". The x-axis mover 1021 is fixedly connected to the x-axis moving plate 101 at one end of the opening of the x-axis U-shaped magnetic circuit 1022.
In one embodiment, the opening of the x-axis U-shaped magnetic circuit 1022 faces the first x-axis slide rail 103. When the opening direction of the x-axis U-shaped magnetic circuit 1022 is toward the first x-axis slide rail 103, the height of the x-axis U-shaped magnetic circuit 1022 below the x-axis moving plate 101 is reduced. And further, the overall height of the x-axis module 100 is reduced, so that the center of gravity of the x-axis module 100 is lowered, and the stability of the x-axis module 100 is improved.
Similarly, the opening direction of the x-axis U-shaped magnetic circuit 1022 may also be toward the second x-axis slide rail 104.
