Description

Technical Field

[0001] The invention relates to the field of mechanical motion mechanisms and optical equipment, and in particular to a vertical motion structure and optical equipment. Background Art

[0002] In traditional optical equipment (such as sequencers), the optical lens is located above the target object (such as the chip on the sequencer), wherein the target object is placed horizontally on a motion platform, and the motion platform is used to move in the X and Y directions of the horizontal plane, so that the optical lens can capture photos of the target object at different positions.

[0003] Among them, in traditional equipment, the object being photographed needs to move a large distance on the moving platform to allow the optical lens to capture the entire surface of the object, resulting in low efficiency in photo collection. At the same time, the large distance will cause the size of the entire machine to be larger, which is not conducive to maintaining high-precision positioning of the object being photographed within the moving distance. In addition, the object being photographed in traditional sequencers can only be placed horizontally, and horizontal placement occupies a large horizontal area, which is not conducive to the miniaturization of the entire machine size. Summary of the invention

[0004] In view of this, it is necessary to provide a vertical motion structure that is conducive to reducing the size of the entire machine, shortening the movement distance from mounting the machine to the shooting position, and facilitating mounting the machine.

[0005] In addition, the present invention also provides an optical device having the vertical surface motion structure.

[0007] In the implementation manner of the present application, the driving mechanism includes a first driving mechanism, and the first driving mechanism is used to drive the rotating mechanism to move along the first direction.

[0008] In an embodiment of the present application, the driving mechanism further includes a second driving mechanism, and the second driving mechanism is used to drive the rotating mechanism to rotate around the first direction and move along the first direction.

[0009] In the implementation manner of the present application, the rotation direction of the second driving mechanism is opposite to the rotation direction of the first driving mechanism, and the first driving mechanism and the second driving mechanism are used to rotate the rotating mechanism around the first direction when they rotate simultaneously.

[0010] In the embodiment of the present application, the connecting rod mechanism includes a rotating seat, a connecting rod seat and a rotating shaft assembly. The rotating seat is sleeved on the rotating mechanism. The end of the rotating seat away from the rotating mechanism is rotatably connected to the connecting rod seat through the rotating shaft assembly. The fixed platform is arranged at one end of the connecting rod seat away from the rotating seat. The rotating mechanism is used to drive the rotating seat to rotate under the drive of the driving mechanism, thereby driving the connecting rod seat to move along the second direction.

[0011] In the embodiment of the present application, the rotating seat is provided with a first positioning hole at one end away from the rotating mechanism, the length of the first positioning hole along the second direction is greater than the length perpendicular to the second direction, the connecting rod seat is provided with a second positioning hole at one end close to the rotating seat, the first positioning hole and the second positioning hole are rotatably connected through the rotating shaft assembly. The rotating seat is used to rotate under the drive of the rotating mechanism, thereby driving the rotating shaft assembly to move along the second direction, so that the connecting rod seat moves along the second direction.

[0014] In the implementation manner of the present application, the fixing platform includes a fixing position, which is used to fix the target object, and the fixing position is arranged along the second direction.

[0015] The present application also provides an optical device, which includes the vertical surface motion structure as described above and an image acquisition device, wherein the image acquisition device is used to acquire the image of the target object located on the fixed platform.

[0016] Compared with the prior art, the vertical motion structure provided by the present invention converts rotational motion into linear motion by setting a connecting rod structure, thereby realizing the position adjustment of the fixed platform along the vertical plane, effectively overcoming the deficiency that the driving mechanism and rails and other components occupy a large space when the fixed platform moves in the horizontal plane, thereby effectively reducing the overall size of the vertical motion structure. By setting the fixed position vertically, it is possible for the image acquisition device to take pictures of the chip on the fixed position from the side of the vertical motion structure; in addition, by placing the chip vertically, the size of the overall vertical motion structure can be effectively reduced. By shortening the distance between the loading position and the fixed position, the loading stroke is effectively shortened, and the loading efficiency, loading accuracy and convenience are improved.

[0032] See also Figure 1, a vertical motion structure 100 provided in an embodiment of the present invention, the vertical motion structure 100 can be used for position adjustment of a chip 6 for nucleic acid detection, and the vertical motion structure 100 includes: a base 1, a rotating mechanism 2, a driving mechanism 3, a connecting rod mechanism 4 and a fixed platform 5. The rotating mechanism 2 is rotatably arranged on the base 1. The driving mechanism 3 is arranged on the base 1 and connected to the rotating mechanism 2. The connecting rod mechanism 4 is connected to the rotating mechanism 2. The fixed platform 5 is arranged on the connecting rod mechanism 4, and the fixed platform 5 is used to fix the target object (i.e., the chip 6). The driving mechanism 3 is used to drive the rotating mechanism 2 to move along a first direction a and rotate around the first direction a. The connecting rod mechanism 4 is used to drive the fixed platform 5 to move along the first direction a under the action of the driving mechanism 3. The connecting rod mechanism 4 is also used to convert the rotation of the rotating mechanism 2 into a movement along a second direction b, thereby driving the fixed platform 5 to move along the second direction b, and the first direction a is perpendicular to the second direction b.

[0033] In this embodiment, the first direction a is a vertical direction, and the second direction b is a horizontal direction. Driven by the driving mechanism 3, the rotating mechanism 2 can realize the linear motion of the target object on the fixed platform 5 in the horizontal and vertical directions through the connecting rod mechanism 4, thereby adjusting the position of the chip 6.

[0034] See also Figure 1 and Figure 2 , combined with reference Figure 1 The base 1 includes a base body 11, a fixing frame 12 fixed on the base body 11, and a through hole 13 arranged on the base body 11. One end of the rotating mechanism 2 extends into the through hole 13 and can move in the through hole 13.

[0035] Please refer again Figure 2 and Figure 4 The rotating mechanism 2 includes a screw rod 21, a track 22 arranged on the screw rod 21, a first coupling 23 sleeved on the screw rod 21, a second coupling 24 sleeved on the screw rod 21, and two nuts 25 arranged at one end of the screw rod 21 away from the seat body 11. One end of the screw rod 21 is arranged through the through hole 13, and the screw rod 21 can rotate in the through hole 13 and can reciprocate along the axis direction of the through hole 13. The connecting rod mechanism 4 is rotatably arranged at the other end of the screw rod 21 away from the through hole 13 through two nuts 25, and the two nuts 25 play a role in stabilizing the connecting rod mechanism 4, so that the connecting rod mechanism 4 is fixed relative to the screw rod 21. The first coupling 23 and the second coupling 24 are limited on the fixing frame 12 by a coupling fixing seat 26, but the first coupling 23 and the second coupling 24 can rotate relative to the coupling fixing seat 26.

[0036] Specifically, the rotating mechanism 2 may be a ball screw spline, the track 22 includes a thread groove 221 spirally arranged on the screw 21 and a straight groove 222 arranged along the axial direction of the screw 21, the first coupling 23 may be a thread spline, the second coupling 24 may be a straight groove spline, and the first coupling 23 and the second coupling 24 are both connected to the driving mechanism 3. The driving mechanism 3 drives the first coupling 23 to rotate, and the first coupling 23 cooperates with the thread groove 221 to achieve linear motion of the screw 21 along the first direction a. The driving mechanism 3 also drives the second coupling 24 to rotate, and the second coupling 24 cooperates with the straight groove 222, thereby achieving linear motion of the screw 21 while rotating around the first direction a. According to the movement requirements, the rotation direction of the second coupling 24 can be opposite to the rotation direction of the first coupling 23. The ball screw spline can be used to convert the rotation of the drive mechanism 3 around the first direction a into the rotation of the screw 21 around the first direction a and the linear motion along the first direction a. Compared with the traditional complex moving mechanism in the horizontal plane, the complexity of the mechanism is greatly reduced, and at the same time, the disadvantage that the driving mechanism and rails moving in the horizontal plane occupy a large space is effectively overcome, thereby effectively reducing the overall size of the vertical motion structure, and the movement is smoother.

[0037] The above-mentioned rotating mechanism 2 has three movement modes: 1. When the second coupling 24 does not rotate, the first coupling 23 rotates to guide the screw rod 21 to make a linear motion along the first direction a; 2. When the first coupling 23 does not rotate, the second coupling 24 rotates to guide the screw rod 21 to rotate around the first direction a while making a linear motion along the first direction a; 3. When the second coupling 24 and the first coupling 23 rotate at the same time and the rotation directions are opposite, the screw rod 21 itself will rotate around the first direction a, and will not make a linear motion along the first direction a.

[0038] See also Figure 3 , combined with reference Figure 2 The driving mechanism 3 includes a first driving mechanism 31 and a second driving mechanism 32. The first driving mechanism 31 is arranged on the first coupling 23, and the second driving mechanism 32 is arranged on the second coupling 24. The first driving mechanism 31 is arranged close to the seat body 11, and the second driving mechanism 32 is arranged close to the connecting rod mechanism 4.

[0039] Please refer again Figure 3 , combined with reference Figure 2The first driving mechanism 31 is used to drive the first coupling 23 to rotate around the first direction a, and the ball in the first coupling 23 cooperates with the threaded groove 221 to realize the linear motion of the screw rod 21 along the first direction a, and then the linear motion of the screw rod 21 along the first direction a is converted into the linear motion of the fixed platform 5 along the first direction a through the connecting rod mechanism 4, thereby realizing the position adjustment of the fixed platform 5 along the first direction a.

[0040] In this embodiment, the first driving mechanism 31 includes a first driving motor 311, a first driving wheel 312 disposed at the output end of the first driving motor 311, a first driven wheel 313 sleeved on the first coupling 23, and a first synchronous belt 314 connecting the first driving wheel 312 and the first driven wheel 313. The first driving motor 311 drives the first driving wheel 312 to rotate around the first direction a, and then drives the first driven wheel 313 to rotate around the first direction a through the first synchronous belt 314, so that the first coupling 23 rotates around the first direction a, and the ball in the first coupling 23 cooperates with the thread groove 221 to realize the linear motion of the lead screw 21 along the first direction a, and finally drives the fixed platform 5 to move linearly along the first direction a through the connecting rod mechanism 4.

[0041] Please refer again Figure 3 , combined with reference Figure 2 The second driving mechanism 32 is used to drive the second coupling 24 to rotate around the first direction a. Through the cooperation between the ball in the second coupling 24 and the straight groove 222, the screw rod 21 can rotate around the first direction a and move linearly along the first direction a at the same time. At this time, the connecting rod mechanism 4 can make the fixed platform 5 move linearly along the first direction a and the second direction b at the same time.

[0042] In addition, in order to make the fixed platform 5 move linearly only in the second direction b, but not in the first direction a, it is necessary to make the first coupling 23 and the second coupling 24 rotate simultaneously and in opposite directions, that is, the direction in which the second drive mechanism 32 drives the second coupling 24 to rotate is opposite to the direction in which the first drive mechanism 31 drives the first coupling 23 to rotate. The second drive mechanism 32 drives the second coupling 24 to rotate around the first direction a, which can make the screw rod 21 rotate around the first direction a and move linearly along the first direction a, thereby making the fixed platform 5 rotate around the first direction a and move linearly along the first direction a. In order to ensure that the fixed platform 5 only moves linearly along the second direction b, but not in the first direction a, it is necessary to add a rotation in the opposite direction to the rotation direction of the second coupling 24, so that the screw rod 21 only rotates along the first direction a, but not in the first direction a. Therefore, by setting the second coupling 24, it is ensured that the fixed platform 5 only moves linearly along the second direction b, but not in the first direction a.

[0043] In this embodiment, the second driving mechanism 32 includes a second driving motor 321, a second driving wheel 322 disposed at the output end of the second driving motor 321, a second driven wheel 323 sleeved on the second coupling 24, and a second synchronous belt 324 connecting the second driving wheel 322 and the second driven wheel 323. The second driving motor 321 drives the second driving wheel 322 to rotate around the first direction a, and then drives the second driven wheel 323 to rotate around the first direction a through the second synchronous belt 324, so that the second coupling 24 rotates around the first direction a, and finally realizes the rotation of the screw rod 21 around the first direction a and the linear motion along the first direction a.

[0044] For the above-mentioned ball screw spline activity process, in short, that is: the first driving mechanism 31 is mainly used to drive the screw 21 to rotate around the first direction a and to make linear motion along the first direction a, and further realize the fixed platform 5 to make linear motion along the first direction a and the second direction b at the same time through the connecting rod mechanism 4; the second driving mechanism 32 is mainly used to drive the screw 21 to make linear motion along the first direction a, and further realize the fixed platform 5 to make linear motion along the first direction a through the connecting rod mechanism 4; and, while the first driving mechanism 31 drives the screw 21 to rotate around the first direction a and to make linear motion along the first direction a, the second driving mechanism 32 can drive the screw 21 to rotate in the opposite direction to offset the linear motion caused by the first driving mechanism 31 driving the screw 21 to rotate, and finally realize that the screw 21 only rotates but does not make linear motion along the first direction a, so that the fixed platform 5 only makes linear motion along the second direction b, and does not make linear motion along the first direction a. Of course, as another embodiment, the functions of the above-mentioned driving mechanisms can be opposite.

[0045] Please refer again Figure 2 , the connecting rod mechanism 4 includes a rotating seat 41, a connecting rod seat 42 and a rotating shaft assembly 43. The rotating seat 41 is sleeved on the rotating mechanism 2, and the end of the rotating seat 41 away from the rotating mechanism 2 is rotatably connected (specifically hinged) to the connecting rod seat 42 through the rotating shaft assembly 43. The fixed platform 5 is arranged at one end of the connecting rod seat 42 away from the rotating seat 41. The rotating mechanism 2 drives the rotating seat 41 to rotate around the first direction a under the drive mechanism 3, and then drives the connecting rod seat 42 to perform reciprocating linear motion along the second direction b, so as to realize the reciprocating linear motion of the fixed platform 5 along the second direction b. The connecting rod mechanism 4 is used to convert the rotation of the rotating mechanism 2 around the first direction a into the linear motion of the fixed platform 5 along the second direction b.

[0046] There can be multiple connecting rod mechanisms 4, which can realize the movement of multiple fixed platforms 5 at the same time.

[0047] In this embodiment, there are two connecting rod mechanisms 4 , and the two connecting rod mechanisms 4 are symmetrically arranged around the screw rod 21 .

[0048] In this embodiment, the two connecting rod mechanisms 4 are an integrated structure.

[0049] See also Figure 4 and Figure 5 , combined with reference Figure 1 , the rotating seat 41 is rotatably arranged at the top of the screw rod 21, and the rotating seat 41 is positioned on the screw rod 21 by two nuts 25, so that the rotating seat 41 does not separate from the screw rod 21 during the rotation process, and the screw rod 21 can drive the rotating seat 41 to rotate. The rotating seat 41 is provided with a first positioning hole 44 at one end away from the rotating mechanism 2, and the length of the first positioning hole 44 along the second direction b is greater than the length perpendicular to the second direction b. The connecting rod seat 42 is provided with a second positioning hole 45 at one end close to the rotating seat 41, and the first positioning hole 44 and the second positioning hole 45 are rotatably connected (specifically hinged) through the rotating shaft assembly 43. The rotating seat 41 rotates under the drive of the rotating mechanism 2, and then drives the rotating shaft assembly 43 to reciprocate along the second direction b, so that the connecting rod seat 42 performs reciprocating linear motion along the second direction b. The first positioning hole 44 is set as a hole with a certain length, so that the rotating shaft assembly 43 has a certain buffer space in the second direction b, which is conducive to the smooth movement of the connecting rod seat 42 along the second direction b.

[0050] In this embodiment, a plurality of first positioning holes 44 may be provided on the rotating seat 41 , so as to be connected to a plurality of connecting rod seats 42 , thereby achieving the purpose of connecting a plurality of fixed platforms 5 .

[0051] In this embodiment, the rotating seat 41 is substantially rectangular, and two first positioning holes 44 are symmetrically arranged about the screw rod 21 at two ends of the rotating seat 41 away from the screw rod 21 .

[0052] In this embodiment, the first positioning hole 44 is a waist-shaped hole, and the length direction of the waist-shaped hole is along the second direction b.

[0053] In this embodiment, the second positioning hole 45 can be a round hole.

[0054] In this embodiment, the connecting rod seat 42 includes a first side wall 421, a second side wall 422 arranged opposite to the first side wall 421, and a connecting wall 423 connecting the first side wall 421 and the second side wall 422. The first side wall 421, the second side wall 422 and the connecting wall 423 jointly enclose a U-shaped accommodating cavity 424, and the second positioning holes 45 are arranged at positions corresponding to the first side wall 421 and the second side wall 422. One end of the rotating seat 41 provided with the first positioning hole 44 extends into the accommodating cavity so that the first positioning hole 44 is coaxial with the two second positioning holes 45, and the rotating shaft assembly 43 passes through the two second positioning holes 45 and the first positioning hole 44 to rotatably connect the rotating seat 41 and the connecting rod seat 42 (specifically, hinged).

[0055] In this embodiment, the second positioning hole 45 can be a round hole.

[0056] In this embodiment, the rotating shaft assembly 43 includes a rotating shaft 431 and an angular contact ball bearing 432. The angular contact ball bearing 432 can ensure the smoothness of the rotation of the rotating shaft 431, thereby making the torque transmission smoother, so as to achieve smoother position movement of the fixed platform 5.

[0057] In this embodiment, the rotating shaft 431 is a cylindrical rotating shaft, and its outer diameter is slightly smaller than the inner diameter of the second positioning hole 45 .

[0058] Please refer again Figure 5 , combined with reference Figure 1 and Figure 4 The connecting rod mechanism 4 further includes an elastic member 46, and two ends of the elastic member 46 respectively abut against the rotating seat 41 and the connecting rod seat 42. The elastic member 46 can assist the rotating shaft 431 in transmitting torque, thereby driving the connecting rod seat 42 to move and provide a resetting elastic force.

[0059] In this embodiment, the end surface of the rotating seat 41 close to the connecting rod seat 42 and the end surface of the connecting wall 423 close to the rotating seat 41 are both rectangular structures. The rotating seat 41 and the connecting rod seat 42 transmit torque only through the rotating shaft 431, which may result in uneven torque transmission, and the torque is concentrated on the rotating shaft 431, which may easily cause fatigue damage to the rotating shaft 431. Therefore, a plurality of elastic members 46 are arranged between the rotating seat 41 and the connecting wall 423, and the plurality of elastic members 46 are respectively distributed around the rotating shaft 431. When the rotating seat 41 rotates to one side, the elastic member 46 on the other side is pressed down by the end surface of the rotating seat 41, so that the torque is uniformly applied to the connecting rod seat 42 through the elastic member 46.

[0060] Please refer again Figure 4 and Figure 5The connecting rod mechanism 4 further includes a roller 47 disposed on the rotating seat 41 and a compensation guide rail 48 disposed on the fixed frame 12. The roller 47 is used to move along the compensation guide rail 48 driven by the connecting rod seat 42. The compensation guide rail 48 extends along the second direction b. The arrangement of the roller 47 and the compensation guide rail 48 can further ensure that the fixed platform 5 moves linearly along the second direction b.

[0061] Please refer again Figure 1 The fixing platform 5 includes a fixing position 51, which is used to fix the chip 6. The fixing position 51 is arranged in the vertical direction so that the chip 6 is arranged in the vertical direction. The present application broadens the way of placing the chip 6 and provides the possibility of taking pictures from the side of the vertical motion structure 100. In addition, by placing the chip 6 vertically, the size of the overall vertical motion structure 100 can be effectively reduced.

[0062] Please refer again Figure 1 The vertical motion structure 100 further includes a loading position 52 disposed on the side of the fixed position 51, and the loading position 52 is loaded with reagents supplied to the chip 6. In the present application, the loading position 52 is close to the fixed position 51, which effectively shortens the loading stroke and improves the loading efficiency, loading accuracy and convenience.

[0063] For details, please refer to Figures 1 to 5 , the action mode of the facade motion structure 100 is described in detail.

[0064] The first movement mode (realizing the reciprocating linear motion of the chip 6 along the first direction a): At this time, the first coupling 23 rotates, and the second coupling 24 does not rotate. Specifically, the first drive motor 311 drives the first driving wheel 312 to rotate around the first direction a, and then drives the first driven wheel 313 to rotate around the first direction a through the first synchronous belt 314, so that the first coupling 23 rotates around the first direction a; the rotation of the first coupling 23 around the first direction a drives the screw 21 to reciprocate linearly along the first direction a through the cooperation of the ball in the first coupling 23 and the threaded groove 221, and then drives the fixed platform 5 and the chip 6 fixed thereon to also reciprocate linearly along the first direction a. It can be understood that the fixed platform 5 can drive the chip 6 to reciprocate linearly along the first direction a through the first drive mechanism 31, the rotating mechanism 2 and the connecting rod mechanism 4.

[0065] The second motion mode (realizing the chip 6 to make reciprocating linear motion in the first direction a and the second direction b at the same time): At this time, the first coupling 23 does not rotate, and the second coupling 24 rotates. Specifically, the second drive motor 321 drives the second driving wheel 322 to rotate around the first direction a, and then drives the second driven wheel 323 to rotate around the first direction a through the second synchronous belt 324, so that the second coupling 24 rotates around the first direction a, and the ball in the second coupling 24 cooperates with the straight groove 222 to drive the screw rod 21 to rotate around the first direction a and make linear motion along the first direction a at the same time. The screw rod 21 rotates around the first direction a to drive the rotating seat 41 to rotate around the first direction a, and then transmits the torque to the connecting rod seat 42 through the cooperation of the rotating shaft assembly 43 and the first positioning hole 44, so that the connecting rod seat 42 makes a reciprocating linear motion along the second direction b, and finally realizes the chip 6 on the fixed platform 5 to make a reciprocating linear motion along the second direction b; at the same time, the reciprocating linear motion of the screw rod 21 along the first direction a will drive the fixed platform 5 and the chip 6 fixed thereon to make a reciprocating linear motion along the first direction a. It can be understood that through the second driving mechanism 32, the rotating mechanism 2 and the connecting rod mechanism 4, the fixed platform 5 can drive the chip 6 to make a reciprocating linear motion in the first direction a and the second direction b at the same time.

[0066] The third motion mode (to achieve reciprocating linear motion of the chip 6 only in the second direction b): At this time, the first coupling 23 and the second coupling 24 rotate in opposite directions at the same time. Specifically, the first drive mechanism 31 drives the first coupling 23 to rotate while the second drive mechanism 32 also drives the second coupling 24 to rotate, and ensures that the rotation direction of the second drive mechanism 32 is opposite to that of the first drive mechanism 31. As described above, when the second drive mechanism 32 drives the second coupling 24 to rotate, the screw rod 21 can be rotated and move linearly in the first direction a at the same time. In order to ensure that the screw rod 21 only rotates but does not move linearly in the first direction a, the first drive mechanism 31 is required to drive the first coupling 23 to rotate in the opposite direction, providing a rotation direction opposite to that of the second coupling 24, so that the screw rod 21 only rotates around the first direction a, and does not move linearly in the first direction a, thereby ensuring that the fixed platform 5 only moves linearly in the second direction b, and does not move linearly in the first direction a, and finally achieves reciprocating linear motion of the chip 6 only in the second direction b.

[0067] The vertical motion structure 100 provided in the embodiment of the present application realizes the position adjustment of the chip 6 by combining the above three motion modes, and the whole action is smoother, and the position adjustment in the horizontal plane is converted into the position adjustment in the vertical plane, which greatly reduces the size of the vertical motion structure 100.

[0068] Figure 1 The process of swapping the fixed positions 51 of the two chips 6:

[0069] First, the second driving mechanism 32 drives the screw rod 21 to rotate and move linearly upward along the first direction a, and the connecting rod mechanism 4 moves upward accordingly, so that the roller 47 is pulled out upward from the compensation guide rail 48;

[0070] Then, the first driving mechanism 31 drives the screw rod 21 to rotate, and the connecting rod mechanism 4 rotates accordingly (specifically, it can be 180°), so that the position of the fixed position 51 is reversed;

[0071] Finally, the second driving mechanism 32 drives the screw rod 21 to rotate in the reverse direction and make a reverse linear motion downward along the first direction a, and the connecting rod mechanism 4 moves downward accordingly, so that the roller 47 is inserted into the compensation guide rail 48, and the fixed position 51 is swapped.

[0072] If in other embodiments, a plurality of fixing positions 51 are provided, the rotation angle of the connecting rod mechanism 4 can be set as required.

[0073] See also Figure 6 The present invention further provides an optical device 200, which includes the vertical motion structure 100 as described above and an image acquisition device 201, wherein the image acquisition device 201 is used to acquire an image of a target object (ie, chip 6) located on the fixed platform.

[0074] In this embodiment, the image acquisition device 201 is arranged on the side of the vertically placed fixing position 51, and can acquire the image of the chip 6 on the facade, thereby facilitating the arrangement of the image acquisition device 201 in the overall optical device 200 and helping to reduce the size of the overall optical device 200.

[0075] Compared with the prior art, the vertical motion structure provided by the present invention converts rotational motion into linear motion by setting a connecting rod structure, thereby realizing the position adjustment of the fixed platform along the vertical plane, effectively overcoming the deficiency that the driving mechanism and rails and other components occupy a large space when the fixed platform moves in the horizontal plane, thereby effectively reducing the overall size of the vertical motion structure. By setting the fixed position vertically, it is possible for the image acquisition device to take pictures of the chip on the fixed position from the side of the vertical motion structure; in addition, by placing the chip vertically, the size of the overall vertical motion structure can be effectively reduced. By shortening the distance between the loading position and the fixed position, the loading stroke is effectively shortened, and the loading efficiency, loading accuracy and convenience are improved.

[0076] In addition, for those skilled in the art, various other corresponding changes and modifications can be made based on the technical concept of the present invention, and all these changes and modifications should fall within the protection scope of the claims of the present invention.
