Description

Technical Field

[0001] This utility model relates to the field of precision adjustment technology, and in particular to a large-stroke XY adjustment platform. Background Technology

[0002] XY adjustment platforms are commonly used devices for adjusting the X and Y axis positions. They typically employ a motor-driven lead screw, which moves the lead screw nut, thereby moving the platform connected to the lead screw nut. In existing solutions, the motor's output shaft is usually connected to the lead screw via a coupling. This method requires space for the coupling, reducing the lead screw nut's range of motion and consequently decreasing the adjustable stroke of the XY adjustment platform, thus limiting its application. Furthermore, existing solutions often include optocouplers and sensors. The sensor passes through the optocoupler's sensing area to determine the specific adjustment position. However, the optocouplers are usually fixed in a few positions, making it inconvenient to adjust their installation location according to actual needs.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a large stroke XY adjustment platform that can make full use of the length of the lead screw to maximize the stroke and facilitate the adjustment of the installation position of the optocoupler according to actual needs.

[0005] The technical solution of this utility model is as follows: A large stroke XY adjustment platform is provided, comprising: a base plate, two first cross roller guides disposed on the base plate, a first drive device disposed on the side of the base plate, a middle plate connected to the two first cross roller guides, a second drive device disposed on the side of the middle plate, two second cross roller guides disposed on the middle plate, and an upper plate connected to the two second cross roller guides.

[0006] The first driving device includes: a first mounting plate and a first support plate connected to the base plate; a first motor mounted on the first mounting plate; a first lead screw connected to the output shaft of the first motor; a first lead screw nut fitted on the first lead screw; and a first connecting member connected to the first lead screw nut. The first connecting member is connected to the middle plate, and the first support plate is used to support the end of the first lead screw that is away from the first motor. The first lead screw and the output shaft of the first motor are integral.

[0007] The second driving device includes: a second mounting plate and a second support plate connected to the middle plate; a second motor mounted on the second mounting plate; a second lead screw connected to the output shaft of the second motor; a second lead screw nut fitted on the second lead screw; and a second connecting member connected to the second lead screw nut. The second connecting member is connected to the upper plate, and the second support plate is used to support the end of the second lead screw that is away from the second motor. The second lead screw and the output shaft of the second motor are integral.

[0008] The middle plate moves along the X-axis, and the upper plate moves along the Y-axis.

[0009] Since the first lead screw is integrated with the output shaft of the first motor and the second lead screw is integrated with the output shaft of the second motor, the space occupied by the coupling is eliminated, which can effectively increase the effective length of the first and second lead screws, thereby increasing the travel of the first lead screw nut and the second lead screw nut and maximizing the travel.

[0010] Furthermore, the base plate is provided with a first groove, and two first cross roller guides are disposed in the first groove to facilitate the installation of the two first cross roller guides.

[0011] Furthermore, the upper plate is provided with a second sliding groove, and two second cross roller guides are disposed in the second sliding groove, which also facilitates the installation of the two second cross roller guides.

[0012] Furthermore, the large-stroke XY adjustment platform also includes: a plurality of first optocouplers mounted on the base plate, and a first sensing plate mounted on the first connector, the movement range of the first sensing plate passing through the sensing area of ​​the first optocoupler. A first mounting groove is provided on the side of the base plate, and the first optocouplers are mounted in the first mounting groove. The first optocouplers can be installed in the position of the first mounting groove according to actual needs, facilitating application.

[0013] Furthermore, the large-stroke XY adjustment platform also includes: a plurality of second optocouplers mounted on the middle plate, and a second sensing plate mounted on the second connector, the movement range of the second sensing plate passing through the sensing area of ​​the second optocoupler. A second mounting slot is provided on the side of the middle plate, and the second optocouplers are mounted in the second mounting slot. The second optocouplers can be installed in the position of the second mounting slot according to actual needs, facilitating application.

[0014] Furthermore, the first driving device also includes: a first cover mounted on the first mounting plate and the first support plate; the first cover covers the first lead screw, the first lead screw nut, and the first connecting member.

[0015] Furthermore, the second drive device also includes: a second cover mounted on the second mounting plate and the second support plate; the second cover covers the second lead screw, the second lead screw nut, and the second connecting member.

[0016] By adopting the above solution, this utility model provides a large stroke XY adjustment platform. Since the first lead screw is integrated with the output shaft of the first motor and the second lead screw is integrated with the output shaft of the second motor, the space occupied by the coupling is eliminated, which can effectively increase the effective length of the first lead screw and the second lead screw, thereby increasing the travel of the first lead screw nut and the second lead screw nut and maximizing the travel.
