Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of linear motor, in particular to a cover plate structure and a linear motor module. BACKGROUND

[0002] The dustproof cover plate of the linear motor module mainly adopts aluminum profile cover plate and steel belt cover plate.

[0003] For the aluminum profile cover plate, when the module length is short (the module length is less than 2 meters), the sagging deformation of the aluminum profile cover plate is small, and there is no problem in use, but when the module length exceeds a certain length (the module length is 2-5 meters), the sagging deformation of the aluminum profile cover plate is prone to occur in the middle of the cover plate due to the structural rigidity and weight problems, which interferes with the sliding table below, especially the sliding table in motion, generates a lot of noise, and affects the normal operation of the linear motor module.

[0004] For the steel belt cover plate, it is mainly applied in long-stroke linear motor module, but the cover plate is prone to sagging and interfere with the sliding table due to its own weight and length problems. CONTENT OF THE INVENTION

[0005] The first object of the present application is to provide a cover plate structure which aims to solve the technical problem that the cover plate is prone to sagging deformation and interfere with the sliding table.

[0006] To achieve the above-mentioned object, the scheme provided by the present application is:

[0007] A cover plate structure applied to a linear motor module, the linear motor module comprising a base and an end plate installed on the base, the cover plate structure comprising:

[0008] a cover plate, which is arranged in a spaced manner with the base;

[0009] an adjusting mechanism, which comprises a mounting seat, a tensioning member and a first adjusting member, the mounting seat being installed on a side of the end plate away from the base, the tensioning member being connected to the mounting seat through the first adjusting member, and the tensioning member being further connected to one end of the cover plate;

[0010] The tensioning member is used to move towards the direction close to or away from the mounting seat under the action of the first adjusting member, so as to drive one end of the cover plate to move towards the direction close to or away from the mounting seat.

[0011] The second object of the present application is to provide a linear motor module, which comprises a base, two end plates, a sliding platform and the above-mentioned cover plate structure, both of the end plates being installed on the base, the cover plate being arranged on both of the end plates and located on a side of the sliding platform away from the base.

[0012] The cover plate structure provided by the application has the following beneficial effects:

[0013] The cover plate structure of the embodiment is provided with a tensioning piece at the end of the cover plate, and the tensioning piece is connected to the mounting seat through the first adjusting piece. Meanwhile, the tensioning piece can drive the end of the cover plate to move towards the mounting seat under the action of the first adjusting piece, so as to shorten the distance between the end of the cover plate and the mounting seat, thereby driving the end of the cover plate to move downwards, tightening the cover plate, making the cover plate straight, and effectively avoiding the deformation and sagging of the cover plate from interfering with the sliding platform.

[0014] On this basis, the tensioning piece can also drive the end of the cover plate to move away from the mounting seat under the action of the first adjusting piece, so as to increase the distance between the end of the cover plate and the mounting seat, thereby driving the end of the cover plate to move upwards. In this way, under the action of the first adjusting piece, the end of the cover plate can be driven to move up and down by the tensioning piece, so that the embodiment can adjust the tightness of the cover plate on the basis of tightening the cover plate, thereby effectively avoiding the phenomenon of cover plate rupture in the process of tightening the cover plate.

The first tensioning portion 221 is connected to the mounting seat 21 through the first adjusting piece, and the first tensioning portion 221 is used to move the end of the cover plate 1 under the action of the first adjusting piece. In specific applications, the first tensioning portion 221 moves the end of the cover plate 1 and the second tensioning portion 222 up and down together under the action of the first adjusting piece to adjust the tightness of the cover plate 1.
