Detailed Description

Referring to fig. 1 and 2, the height adjustment device 100 includes a mounting bracket 110, a driving portion 120, and a height adjustment rail 130. In the height adjustment state, the driving part 120 can drive the mounting bracket 110 to move along the height adjustment guide 130; in the non-height-adjustment state, the drive portion 120 remains locked with respect to the height-adjustment rail 130. These components will be described one by one below.

The mounting bracket 110 has a base 111 for mounting the workpiece 200 and guide portions 112a, 112b connected to the base 111. As shown, the guide portion 112a is disposed on the same side of the height-adjustment rail 130 as the base 111, and the guide portion 112b is disposed on the other side of the height-adjustment rail 130. At this time, the guide portions 112a and 112b perform a guide function with respect to the height-adjustment rail 130. In the height-adjustment state, the guide portions 112a and 112b can ensure that the driving portion 120 performs the elevating movement along the height-adjustment guide rail 130 without movement in other directions; and in the non-height-adjustment state, the guide portions 112a, 112b remain stationary with respect to the height-adjustment rail 130.

In addition, the height adjustment device 100 further includes a plurality of rollers 140a, 140 b; the plurality of rollers 140a, 140b are disposed between the guide portions 112a, 112b and the height-adjustment rail 130, and serve to reduce frictional force between the guide portions 112a, 112b and the height-adjustment rail 130. Through the arrangement of the rollers, when the guide portions 112a and 112b and the height adjustment guide rail 130 perform relative movement in the vertical direction, the friction force between the two is changed from sliding friction in direct contact to rolling friction, so that the friction force between the two is greatly reduced, and further, the two can perform smooth and stable relative movement.

With continued reference to fig. 1, in this embodiment, rollers 140a, 140b are provided on the driving portion 120 on both sides of the height-adjustment rail 130, respectively, so as to reduce friction at the contact surface therebetween on both sides, thereby providing a smoother relative movement.

Referring to fig. 2, more specifically, the roller 140a on the guide 112a on the same side as the base 111 is disposed below the base 111; and the roller 140b of the guide portion 112b on the opposite side of the base 111 is disposed above the base 111. In this case, the guide portions 112a and 112b can perform both rotational movement with respect to the height adjustment rail 130 and lifting movement with respect to the height adjustment rail 130. For example, in a conventional height adjusting state, the driving part 120 may be directly controlled to drive the base 110 to move up and down along the Y direction defined by the guiding parts 112a and 112b and the height adjusting guide 130. At this time, since the rollers 140a and 140b are provided between the guide portions 112a and 112b and the height-adjusting guide rail 130, a rolling friction force is provided therebetween, so that the relative movement therebetween has a relatively smooth speed, so as to precisely adjust the target height of the workpiece on the height-adjusting device. It is desirable to move the base and the workpiece thereon at a faster speed if the workpiece is at a greater distance from the target height. At this time, the guide portions 112a, 112b may be first rotated in the X direction so that contact between the guide portions 112a, 112b and the height-adjustment rail 130 no longer occurs. Then, the driving part 120 is controlled to drive the base 110 to perform relatively faster lifting motion along the Y direction defined by the height adjusting guide 130, so that the workpiece 200 can approach the target height faster. Thereafter, the step of precisely adjusting the height is performed. The height adjusting mode simultaneously considers high efficiency and accuracy.

On the other hand, as for the driving part 120, it is connected to the mounting bracket 110 and serves to drive the mounting bracket 110 to perform an elevating movement in a direction defined by the guide parts 112a, 112b with respect to the height-adjustment rail 130. And a height adjustment guide 130 which is engaged with the driving part 120 and provides a motion track for the driving part 120;

as a specific implementation, the driving part 120 may include a worm 121, and the height-adjustment rail 130 may include a rack 131. At this time, the worm 121 and the rack 131 are engaged with each other, so that the base 111 and the workpiece 200 on the base 111 are driven to move up and down, and highly accurate position adjustment is achieved.

A wireless communication module may also be included to communicate with the height adjustment device 100, the workpiece 200 to be mounted, or both. Such as a bluetooth module, etc. Therefore, the remote control of the height adjusting device can be realized, and the self function of the installation workpiece can be remotely controlled.

Optionally, the set of height adjustment devices 100 may further include a power module 150 disposed on the base 111, thereby enabling power supply to the driving part. Alternatively, in another implementation form, it is also possible to use the energy supply module of the workpiece to be mounted to supply energy to the height adjustment device directly, without providing a separate energy supply module for the height adjustment device. Such self-contained power modules are well known in the art, and as described in chinese patent ZL201620824510.5, they will not be described herein.

Further, an electric power transmission line may be further provided on the height-adjustment guide rail 130. For example, it is disposed on both sides of the rack gear 131 on the height-adjustment rail 130. On the one hand, the power transmission line can be used for transmitting signals between the height adjusting device 100 and the workpiece 200 to be mounted, so that the remote communication control of the height adjusting device 100 and the workpiece 200 to be mounted is realized, and the height adjusting device 100 can be controlled to perform height adjustment and the workpiece 200 to be mounted can be controlled to perform working behaviors; on the other hand, the electric power transmission line may also be used as a power supply line, thereby realizing the supply of electric power to the height adjusting device 100.

As one of the specific application scenarios of the embodiment of the height adjusting apparatus 100, it can be applied to height adjustment of a laser tool. At this time, the workpiece 200 to be mounted is a laser tool. Through the lifting movement of the driving part in the height adjusting device 100 along the height adjusting guide rail 130, the base 111 and the laser tool on the base 111 are driven to adjust the height, so that the laser tool is accurately positioned on a vertical coordinate, and functions such as laser measurement or laser etching are realized.

The above detailed description is merely illustrative of the present application and is not intended to be limiting. In the present application, relative terms such as left, right, up, and down are used to describe relative positional relationships, and are not intended to limit absolute positions. Various changes and modifications can be made by one skilled in the art without departing from the scope of the present application, and all equivalent technical solutions also belong to the scope of the present application, and the protection scope of the present application should be defined by the claims.
