DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 A super-heavy-load lens translation device includes a translation mechanism 2 arranged on an optical platform 1, the translation mechanism 2 includes a support seat 21 installed on the optical platform 1, a limit top plate 22 located above the support seat 21, a support bottom plate 23 directly placed on the optical platform 1, and a control component 24 for adjusting the vertical distance between the support bottom plate 23 and the limit top plate 22, a limit cover 26 is fixedly installed on the optical platform 1, and a stabilizing eaves 25 is arranged in the limit cover 26, such as Figure 2 As shown, the stabilizing eaves 25 is a rectangular frame structure and is fixedly connected to the limiting top plate 22 through a connecting plate. A loading rack 4 is fixedly installed on the supporting bottom plate 23, and the loading rack 4 is used to install the lens 3. In the initial state, the control component 24 keeps a fixed distance between the stabilizing eaves 25 and the supporting bottom plate 23. Under this distance, the top surface of the stabilizing eaves 25 is against the limiting cover 26. The supporting bottom plate 23 is stably located on the optical platform 1 under the action of gravity. The supporting bottom plate 23 provides a stable installation environment and working environment for the lens 3 through the loading rack 4. During the position adjustment process of the lens 3, it is only necessary to control the component 24 to reduce the distance between the limiting top plate 22 and the supporting bottom plate 23, so as to provide a rolling friction translation environment for the lens 3, and flexibly adjust the position of the lens 3, such as Figure 5 As shown, in the process of reducing the distance between the limit top plate 22 and the supporting bottom plate 23, the limit top plate 22 and the stabilizing eaves 25 move downward first. In this process, the stabilizing eaves 25 are first separated from the limit cover 26, and then the limit top plate 22 contacts the support seat 21 and stops moving downward under the limit of the support seat 21, and then the supporting bottom plate 23 moves up until it is separated from the optical platform 1. At this time, under the rolling contact between the limit top plate 22 and the supporting seat 21, the position of the lens 3 can be flexibly and conveniently adjusted until the lens 3 is aligned with the optical axis of the detection system. After that, it is only necessary to control the component 24 to increase the distance between the reset limit top plate 22 and the supporting bottom plate 23 until the supporting bottom plate 23 is reset to the position placed on the optical platform 1 and the limit top plate 22 is reset to the state against the limit cover 26, so that the lens 3 can be stably in the current position state. The present invention can not only fully meet the demand for flexible translation of the overloaded lens 3, but also has the advantages of simple overall structure, convenient operation and easy control, and high reliability and safety.

[0024] participate Figure 2 , Figure 3 and Figure 4 The support seat 21 includes a plurality of ball seats 211, on which a universal ball 212 is mounted, and the ball seats 211 are fixedly mounted on the optical platform 1, and the limit top plate 22 corresponds to the universal ball 212 one by one, and the universal ball 212 contacts the corresponding limit top plate 22 and forms a plurality of support points, such as Figure 2 As shown, there are four ball seats 211 in number and they are distributed in a rectangular shape. When the limiting top plate 22 moves downward, it directly contacts the universal ball 212. The universal ball 212 forms four supporting points to limit the limiting top plate 22. During the process of adjusting the position of the lens 3, the limiting top plate 22 and the universal ball 212 are in rolling contact, so the position of the lens 3 can be flexibly adjusted.

[0025] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 The stabilizing eaves 25 are provided with buffer heads 28, which are distributed in a rectangular shape. The limiting cover 26 is a rectangular structure, and the four sides of the limiting cover 26 correspond to the buffer heads 28 distributed in a rectangular shape. In the process of translating the lens 3 to adjust its position, the stabilizing eaves 25 will not contact the corresponding side of the limiting cover 26. Before the stabilizing eaves 25 is about to contact the corresponding side of the limiting cover 26, the buffer head 28 first contacts the limiting cover 26 and provides a reaction force within a certain range to suppress the translation of the lens 3, so as to avoid the lens 3 colliding due to excessive translation speed. The buffer head 28 includes a connecting rod 282 with a rolling contact end 281 and a connecting seat 283 horizontally slidably connected to the connecting rod 282. A spring is provided between the connecting rod 282 and the connecting seat 283. The connecting seat 283 is fixedly mounted on the side of the stable eaves 25, such as Figure 4 As shown, when the buffer head 28 contacts the corresponding side of the limiting cover 26, the rolling contact end 281 directly rolls with the corresponding side of the limiting cover 26, so that the buffer head 28 can play a buffering role without affecting the flexibility of the movement and adjustment of the lens 3.

[0026] participate Figure 2 , Figure 4 and Figure 7The control assembly 24 includes a unified driving member 241 and a plurality of screw members 243 coaxially connected with an adjusting gear 242. The screw members 243 all pass through the limit top plate 22 and are threadedly connected to the support bottom plate 23, and the screw members 243 are rotatably connected to the corresponding limit top plate 22. The adjusting gear 242 on the screw member 243 is located above the limit top plate 22. The unified driving member 241 meshes with the adjusting gear 242 and synchronously controls the rotation of the screw member 243. Figure 4 and Figure 7 As shown, the limiting top plate 22 corresponds to the ball seat 211 one by one and is distributed in a rectangular shape. Each limiting top plate 22 is connected to the supporting bottom plate 23 through four screw members 243. The unified driving member 241 includes a mounting seat 2411, which is located above the limiting top plate 22 and fixedly mounted on the connecting plate. The mounting seat 2411 is equipped with a central gear 2412, four control gears 2414 coaxially connected to the conversion gear 2413, and a driving gear 2416 coaxially connected to the control end 2415. The control gear 2414 corresponds to the limiting top plate 22 one by one, and the four screw members of the corresponding limiting top plate 22 The adjusting gears 242 on the rod 243 are all meshed with the corresponding control gears 2414, the conversion gears 2413 on the control gears 2414 are all meshed with the central gear 2412, and the driving gear 2416 is meshed with the central gear 2412. It is only necessary to control the driving gear 2416 to rotate through the control end 2415 to synchronously drive the screw member 243 to rotate, and the limiting top plate 22 moves downward first. When the limiting top plate 22 contacts the universal ball 212 and stops moving downward under the support limit of the universal ball 212, the screw member 243 continues to rotate, and the supporting bottom plate 23 threadedly connected thereto begins to move upward and separate from the optical platform 1.

[0027] See also Figure 4 and Figure 5 A limiting member 27 is provided between the limiting top plate 22 and the supporting bottom plate 23. The limiting member 27 corresponds to the screw member 243 one by one and is sleeved on the corresponding screw member 243. The limiting member 27 is used to limit the minimum distance between the limiting top plate 22 and the supporting bottom plate 23 to avoid the supporting bottom plate 23 from moving up too high, which affects the stability and reliability of the translation process of the lens 3, and accordingly further improves the safety and reliability of the adjustment process of the lens 3.
