For example, when optical measurement equipment detects chips, it has high requirements for the verticality of the upper surface of the wafer and the optical axis of the lens. After the chip is fixed to the workbench, the upper surface of the wafer needs to be kept level. In order to ensure that the workpiece is in a horizontal state, the mechanical equipment currently on the market is equipped with a leveling device. The leveling device is installed on the workbench, and the workpiece is fixed to the leveling device. The leveling device can level the workpiece. However, the leveling devices currently on the market are prone to deformation, and the product life is not high. Summary of the invention

[0004] The first aspect of the present application provides a leveling device, including a base, an adjusted plate and a leveling assembly. Along a first direction, the base and the adjusted plate are spaced apart from each other, and the leveling assembly is arranged between the base and the adjusted plate.

The center of the projection of the connecting member along the first direction coincides with the center of the projection of the driving member along the first direction. Along the first direction, the driving member, the connecting member and the adjusted plate are relatively fixed, and the driving member can move relative to the base along the first direction so that the mounting surface of the adjusted plate is parallel to the horizontal plane.
[0005] In this embodiment, the leveling device is applied to mechanical equipment, the base of the leveling device is installed on the workbench of the mechanical equipment, the surface of the adjusted plate away from the base is used as the mounting surface, and the mounting surface is used to fix the workpiece. The leveling device can move relative to the workbench to facilitate the mechanical equipment to detect or process the workpiece. The leveling device has a leveling function, and the adjusted plate can swing relative to the base in a first direction under the action of the leveling component so that the mounting surface is parallel to the horizontal plane.
[0006] Among them, the center of the projection of the connecting member along the first direction coincides with the center of the projection of the driving member along the first direction, so that the leveling force and the tightening force generated by the leveling assembly during the leveling process coincide, and the leveling force and the tightening force will not generate bending moment on the adjusted plate, thereby avoiding deformation of the adjusted plate, ensuring the flatness of the installation surface of the adjusted plate, and improving the service life of the product.

The driving member is threadedly connected to the base, and the staff can use a wrench or a screwdriver to turn the driving member, so that the driving member can move relative to the base along the first direction, which is simple to operate and easy to adjust.
[0008] In some embodiments, the base is further provided with an isolation groove, a first fixing member and a second fixing member, and along the first direction, the isolation groove penetrates the outer circumference of the base and the inner circumference of the threaded hole. The first fixing member and the second fixing member are arranged on the outer circumference of the base, and the first fixing member and the second fixing member are respectively located on both sides of the isolation groove. There is a gap between the first fixing member and the second fixing member, and the gap between the first fixing member and the second fixing member is connected to the isolation groove. The leveling device also includes a reinforcement member, which is connected to the first fixing member and the second fixing member respectively, and the reinforcement member can adjust the gap between the first fixing member and the second fixing member to adjust the width of the isolation groove so that the aperture of the threaded hole changes.
[0009] After the adjusted plate is leveled, the staff adjusts the reinforcement piece so that the first fixing piece and the second fixing piece are closer to each other and the interval between the first fixing piece and the second fixing piece becomes smaller, so that the width of the isolation groove becomes smaller, and then the aperture of the threaded hole becomes smaller, the driving piece is clamped tighter by the wall surface of the threaded hole, the connection between the driving piece and the base is more stable, and the height of the driving piece in the first direction will not change easily, so that after the adjusted plate is leveled, the installation surface can be parallel to the horizontal plane for a long time.

The angle between the first groove wall surface and the reference surface is an obtuse angle, and the angle between the second groove wall surface and the reference surface is an obtuse angle, and the reference surface is perpendicular to the first direction.

[0012] By setting the mounting block and setting the mounting groove on the mounting block, it is helpful to reduce the thickness of the plate to be adjusted, thereby reducing the weight of the leveling device. In addition, by setting the spherical abutment surface to abut the first groove wall surface and the second groove wall surface, the driving member and the mounting block are in point contact, the force area between the driving member and the mounting block is smaller, and the abutment force of the driving member on the mounting block is more concentrated, so that the leveling force transmitted by the mounting block to the plate to be adjusted is more concentrated, which is more conducive to avoiding the bending moment generated on the plate to be adjusted between the leveling force and the tightening force, thereby avoiding the deformation of the plate to be adjusted due to force, and the service life of the product is longer.

The thread is provided on the outer peripheral surface of the driving section 111, and the spherical abutment surface 1121 is provided on the abutment section 112. Along the Y-axis direction, the receiving cavity 1111 is recessed in the lower surface of the driving section 111, and the lower surface of the driving section 111 is the surface of the driving member 110 away from the adjusted plate 300. It can be understood that the surface of the driving member 110 away from the adjusted plate 300 is provided with the receiving cavity 1111. The through hole 1122 penetrates the bottom surface of the receiving cavity 1111 and the surface of the abutment section 112 away from the receiving cavity 1111.
[0057] For some examples, please refer to Fig.11 , Fig.11 yes Figure 2 The structure diagram of the connecting member 120 of the leveling device 1000 is shown. The connecting member 120 includes a connecting section 121 and a stopper 122. The stopper 122 is fixedly connected to the connecting section 121 along the Y-axis direction. In this embodiment, the connecting member 120 is a screw, the connecting section 121 is the threaded portion of the screw, and the stopper 122 is the head of the screw. In other embodiments, the connecting member 120 may be a bolt.
[0058] For some examples, please refer to Fig.12 , Fig.12 yes Figure 2 The cross-sectional view of the leveling device 1000 shown is cut along the line L3-L3. Along the Y-axis direction, the positioning pin 400 is arranged between the base 200 and the adjusted plate 300, one end of the positioning pin 400 is connected to the central hole 210 of the base 200, and the other end of the positioning pin 400 is connected to the swing groove 310 of the adjusted plate 300. Specifically, along the Y-axis direction, the end of the support rod 420 away from the ball head 410 is fixedly connected to the central hole 210 of the base 200 by means including but not limited to welding, bonding, threaded connection or interference fit, that is, the fixed section 422 of the support rod 420 is fixedly connected to the central hole 210 of the base 200, and the step surface 423 abuts the upper surface of the base 200. The ball head 410 extends into the swing groove 310 of the adjusted plate 300, and the spherical surface 411 of the ball head 410 contacts the groove side of the swing groove 310. When the driving member 110 moves relative to the base 200 along the Y-axis direction, the adjusted plate 300 can swing around the center of the ball head 410 along the Y-axis direction. During the swinging process of the adjusted plate 300, the spherical surface 411 of the ball head 410 slides relative to the groove side of the swing groove 310. It can be understood that the adjusted plate 300 is connected to the base 200 through the positioning pin 400, and the adjusted plate 300 can swing relative to the base 200.
[0059] In this embodiment, since the spherical surface 411 of the ball head 410 and the groove side of the swing groove 310 are both spherical, after the ball head 410 is inserted into the swing groove 310, the ball head 410 and the adjusted plate 300 will not be easily separated, thereby improving the stability of the connection between the adjusted plate 300 and the base 200. During the swinging process of the adjusted plate 300, the spherical surface 411 of the ball head 410 and the groove side of the swing groove 310 slide relative to each other, so that the adjusted plate 300 can swing more smoothly, and the stability of the adjusted plate 300 during the swinging process is higher. In other embodiments, the positioning pin 400 can also be omitted.
[0060] For some examples, please refer to Fig.13 and Fig.14 , Fig.13 yes Figure 2 The leveling device 1000 is shown in a cross-sectional view taken along line L4 - L4. Fig.14 yes Fig.13 The enlarged view of the A of the leveling device 1000 is shown. In this embodiment, the connection relationship between the plurality of mounting blocks 500 and the adjusted plate 300 is consistent, and the following only describes the connection relationship between one of the mounting blocks 500 and the adjusted plate 300. The connection relationship between the plurality of leveling assemblies 100 and the base 200 and the mounting block 500 is consistent, and the following only describes the connection relationship between one of the leveling assemblies 100 and the base 200 and the mounting block 500.
[0061] In this embodiment, along the Y-axis direction, the mounting block 500, the driving member 110 and the connecting member 120 are arranged between the base 200 and the adjusted plate 300. The mounting block 500 is fixedly connected to the side of the adjusted plate 300 facing the base 200, and the mounting block 500 is arranged at a distance from the base 200. Along the Y-axis direction, one end of the driving member 110 is connected to the base 200, the other end of the driving member 110 is connected to the mounting block 500, one end of the connecting member 120 is connected to the driving member 110, and the end of the connecting member 120 away from the driving member 110 is connected to the mounting block 500.
[0062] Specifically, along the Y-axis direction, by means including but not limited to welding, bonding, threaded connection or interference fit, the positioning column 510 of the mounting block 500 extends into the corresponding positioning hole 320, and the upper surface of the mounting block 500 abuts against the lower surface of the adjusted plate 300. By setting the positioning column 510 and the positioning hole 320 to cooperate with each other, it is beneficial to improve the assembly accuracy, the assembly error between the parts is small, and then the leveling accuracy of the leveling device 1000 is improved. In other embodiments, the positioning hole 320 is provided on the mounting block 500, and the positioning column 510 is provided on the adjusted plate 300. In other embodiments, both the positioning hole 320 and the positioning column 510 can be omitted.
[0063] The driving section 111 of the driving member 110 is threadedly connected with the threaded hole 221 of the corresponding connecting portion 220, and the spherical abutting surface 1121 of the abutting section 112 abuts against the first groove wall surface 521 and the second groove wall surface 522 of the corresponding mounting groove 520. It can be understood that the spherical abutting surface 1121 of the abutting section 112 indirectly abuts against the adjusted plate 300 through the mounting block 500, so as to achieve the indirect connection of the adjusted plate 300 with the end of the driving member 110 away from the base 200. The end of the connecting section 121 of the connecting member 120 away from the limiting block 122 passes through the receiving cavity 1111 and the through hole 1122 of the driving member 110 in sequence, and is threadedly connected with the connecting hole 530 of the corresponding mounting block 500. It can be understood that the end of the connecting section 121 of the connecting member 120 away from the limiting block 122 is indirectly connected to the adjusted plate 300 through the mounting block 500. The limit block 122 is received in the receiving cavity 1111, and the limit block 122 abuts against the bottom surface of the receiving cavity 1111. It can be understood that the limit block 122 abuts against the side of the driving member 110 away from the adjusted plate 300, so that one end of the connecting member 120 is connected to the driving member 110. The connecting member 120 is coaxial with the driving member 110, and the axial direction of the connecting member 120 and the axial direction of the driving member 110 are both parallel to the Y-axis direction.
[0064] In this embodiment, by setting the connecting member 120 to pass through the driving member 110, the structure of the leveling assembly 100 is simple and easy to assemble. The limit block 122 is accommodated in the accommodating cavity 1111, making the structure of the leveling assembly 100 more compact. By setting the connecting member 120 as a screw, the structure is simple and easy to assemble.
[0065] In this embodiment, since the driving member 110 is threadedly connected to the base 200, the driving member 110 can rotate around the axial direction of the connecting member 120. When the driving member 110 rotates around the axial direction of the connecting member 120, the driving member 110 moves along the Y-axis direction to drive the mounting block 500 to move along the Y-axis direction, and the mounting block 500 then drives the adjusted plate 300 to swing along the Y-axis direction around the center of the ball head 410 of the positioning pin 400, so that the mounting surface 301 of the adjusted plate 300 is parallel to the horizontal plane.
[0066] Specifically, if the staff finds that one side of the adjusted plate 300 is tilted downward and the other side of the adjusted plate 300 is tilted upward, that is, the mounting surface 301 is not parallel to the horizontal plane, the staff can use a wrench or a screwdriver to rotate multiple driving members 110 so that some of the driving members 110 move upward and other driving members 110 move downward. Among them, the abutting section 112 of the driving member 110 that moves upward abuts against the mounting block 500 to move upward, and the mounting block 500 abuts against the side of the adjusted plate 300 that tilts downward and swings upward. The driving member 110 that moves downward abuts against the limiting block 122 of the connecting member 120 to drive the connecting member 120 to move downward, the connecting member 120 drives the mounting block 500 to move downward, and the mounting block 500 drives the side of the adjusted plate 300 that tilts upward to swing downward. Then, the adjusted plate 300 is adjusted to a horizontal state, that is, the mounting surface 301 is parallel to the horizontal plane.
[0067] For some examples, please refer to Fig.15 , Fig.15 yes Figure 2 The leveling device 1000 is a cross-sectional view taken along line L5-L5 (the adjusted plate 300 and the mounting block 500 are omitted). The leveling device 1000 further includes a reinforcing member 600, which is respectively connected to the first fixing member 223 and the second fixing member 224 of the connecting portion 220. The reinforcing member 600 can adjust the interval between the first fixing member 223 and the second fixing member 224 to adjust the width of the isolation groove 222, so that the aperture of the threaded hole 221 changes.
[0068] Specifically, there are multiple reinforcement members 600, and the multiple reinforcement members 600 are connected to the first fixing members 223 and the second fixing members 224 of the multiple connecting parts 220 in a one-to-one correspondence. In this embodiment, the number of reinforcement members 600 is three, and in other embodiments, the number of reinforcement members 600 can be one, two, or four or more. The reinforcement member 600 is a screw, and in other embodiments, the reinforcement member 600 can be a bolt. The threaded portion of the reinforcement member 600 passes through the countersunk hole 2241 and the second fixing hole 2242 of the second fixing member 224 in sequence, and is threadedly connected with the first fixing hole 2231 of the first fixing member 223, and the head of the reinforcement member 600 is received in the countersunk hole 2241 and abuts against the bottom surface of the countersunk hole 2241.
[0069] After the adjusted plate 300 is leveled, the staff tightens the reinforcement 600 so that the first fixing member 223 and the second fixing member 224 are locked tighter, the first fixing member 223 and the second fixing member 224 are closer to each other, and the interval between the first fixing member 223 and the second fixing member 224 becomes smaller, so that the width of the isolation groove 222 becomes smaller, and then the aperture of the threaded hole 221 becomes smaller, the driving member 110 is clamped tighter by the hole wall of the threaded hole 221, the connection between the driving member 110 and the base 200 is more stable, and the height of the driving member 110 in the Y-axis direction will not change easily, so that after the adjusted plate 300 is leveled, the mounting surface 301 can remain horizontal for a long time.
[0070] In this embodiment, please refer to Fig.16 and Fig.17 , Fig.16 It is a force analysis diagram when the driving member 110 provided in the embodiment of the present application moves upward. Fig.17 This is a force analysis diagram of the driving member 110 provided in the embodiment of the present application when it moves downward. The design that the center of the projection of the connecting member 120 along the Y-axis direction coincides with the center of the projection of the driving member 110 along the Y-axis direction makes the leveling force F1 of the driving member 110 on the adjusted plate 300 and the fastening force F2 of the connecting member 120 on the adjusted plate 300 more concentrated, and the leveling force F1 and the fastening force F2 coincide.
[0071] Specifically, in this embodiment, when the adjusted plate 300 needs to swing upward, the driving member 110 moves upward, and the driving member 110 abuts against the first groove wall 521 and the second groove wall 522 of the mounting block 500, respectively. The driving member 110 gives the first groove wall 521 an abutting force F11, and the driving member 110 gives the second groove wall 522 an abutting force F12, and the magnitudes of F11 and F12 are equal. The mounting block 500 then transmits the two abutting forces F11 and F12 to the adjusted plate 300. It can be understood that the driving member 110 indirectly acts on the adjusted plate 300 through the mounting block 500. Through force analysis, it can be obtained that the resultant force of F11 and F12 is the leveling force F1, and the leveling force F1 coincides with the axial direction of the driving member 110, that is, the leveling force F1 coincides with the axial direction of the connecting member 120. One end of the connecting member 120 is threadedly connected to the mounting block 500 to indirectly connect to the adjusted plate 300. The connecting member 120 indirectly applies the fastening force F2 to the adjusted plate 300 through the mounting block 500. The fastening force F2 coincides with the axial direction of the connecting member 120. Therefore, the leveling force F1 coincides with the fastening force F2.
[0072] When the adjusted plate 300 needs to swing downward, the driving member 110 moves downward, and the driving member 110 abuts against the limit block 122 of the connecting member 120 to drive the connecting member 120 to move downward, and the connecting member 120 drives the mounting block 500 to move downward, and the mounting block 500 then drives the adjusted plate 300 to swing downward. In this process, the connecting section 121 of the connecting member 120 applies a leveling force F1 to the mounting block 500, and the mounting block 500 then applies the leveling force F1 to the adjusted plate 300, so that the adjusted plate 300 can swing downward. At this time, the leveling force F1 coincides with the axial direction of the connecting member 120, so the leveling force F1 coincides with the fastening force F2.
[0073] For other embodiments, please refer to Fig.18 , Fig.18 yes Figure 2 The leveling device 1000 shown is a cross-sectional view taken along the L4-L4 line under another embodiment (two leveling components 100 are omitted). In this embodiment, the mounting block 500 can be omitted, and the mounting groove 520 and the connecting hole 530 are both provided on the adjusted plate 300. The spherical abutting surface 1121 of the abutting section 112 directly abuts against the first groove wall surface 521 and the second groove wall surface 522 of the adjusted plate 300, so as to achieve that the end of the driving member 110 away from the base 200 is directly connected to the adjusted plate 300. The connecting section 121 of the connecting member 120 is threadedly connected to the connecting hole 530 of the adjusted plate 300, so as to achieve that the end of the connecting member 120 away from the driving member 110 is directly connected to the adjusted plate 300. In this embodiment, the force analysis of the leveling device 1000 can refer to Fig.16 and Fig.17 The force analysis of the leveling device 1000 of this embodiment is different from that of the above-mentioned embodiment in that the fastening force F2 of the connecting member 120 directly acts on the adjusted plate 300. When the driving member 110 moves upward, the two abutting forces F11 and F12 of the driving member 110 directly act on the adjusted plate 300. When the driving member 110 moves downward, the driving member 110 drives the connecting member 120 to move downward, and the connecting member 120 drives the adjusted plate 300 to swing downward. In this process, the connecting member 120 directly applies the leveling force F1 to the adjusted plate 300.
[0074] For some examples, please refer to Fig.19 , Fig.19 yes Figure 2 The leveling device 1000 is shown in a cross-sectional view taken along line L4-L4 in another embodiment (two leveling components 100 are omitted). In this embodiment, the mounting block 500 is omitted, and the plate 300 to be adjusted is not provided with a mounting groove 520, the upper surface of the abutting section 112 of the driving member 110 directly abuts against the lower surface of the plate 300 to be adjusted, and the connecting section 121 of the connecting member 120 is threadedly connected to the connecting hole 530 of the plate 300 to be adjusted.
[0075] In this embodiment, the force analysis of the leveling device 1000 is as follows: Fig.19 As shown, when the driving member 110 moves upward, the upper surface of the abutment section 112 applies abutment forces F11 and F12 to the adjusted plate 300. F11 and F12 are equal in magnitude and directed in the positive direction of Y. The resultant force of F11 and F12 is the leveling force F1. The leveling force F1 is directed in the positive direction of the Y axis. The leveling force F1 coincides with the axial direction of the driving member 110, that is, the leveling force F1 coincides with the axial direction of the connecting member 120.
[0076] When the driving member 110 moves downward, the driving member 110 drives the connecting member 120 to move downward, and the connecting member 120 drives the adjusted plate 300 to swing downward. During this process, the connecting member 120 applies a leveling force F1 to the adjusted plate 300, so that the adjusted plate 300 swings downward, and the leveling force F1 is toward the negative direction of the Y-axis, and the leveling force F1 coincides with the axial direction of the connecting member 120.
[0077] The fastening force F2 of the connecting member 120 on the adjusted plate 300 is toward the negative direction of the Y axis, and the fastening force F2 coincides with the axial direction of the connecting member 120 . Therefore, when the driving member 110 moves upward or downward, the leveling force F1 coincides with the fastening force F2 .
[0078] In summary, the design in which the center of the projection of the connecting member 120 along the Y-axis direction coincides with the center of the projection of the driving member 110 along the Y-axis direction makes the leveling force F1 and the tightening force F2 generated by the leveling component 100 during the leveling process coincide, and the leveling force F1 and the tightening force F2 will not generate bending moment on the adjusted plate 300, thereby avoiding deformation of the adjusted plate 300, improving the service life of the product, and ensuring the flatness of the mounting surface 301 of the adjusted plate 300. After the workpiece is installed on the mounting surface 301, the workpiece is placed more flat, so that the detection accuracy or processing accuracy of the mechanical equipment 1 for the workpiece is higher.
[0079] At the same time, the design also makes the structure of the leveling assembly 100 more compact, which is conducive to saving space. The driving member 110 and the adjusted plate 300 can be connected by only one connecting member 120, which has a simple structure and is easy to assemble.
[0080] In this embodiment, by setting the spherical abutting surface 1121 to abut the first groove wall surface 521 and the second groove wall surface 522 of the installation groove 520, the driving member 110 and the installation block 500 are in point contact, the force-bearing area between the driving member 110 and the installation block 500 is small, and the abutting force of the driving member 110 on the installation block 500 is more concentrated, so that the leveling force transmitted by the installation block 500 to the adjusted plate 300 is more concentrated, which is more conducive to avoiding the bending moment generated on the adjusted plate 300 between the leveling force and the fastening force, thereby avoiding the deformation of the adjusted plate 300 under force, and the service life of the product is longer. Similarly, when the installation block 500 is omitted and the installation groove 520 is set on the adjusted plate 300, it is also more conducive to avoiding the bending moment generated on the adjusted plate 300 between the leveling force and the fastening force.
[0081] In this embodiment, since the depth of the mounting groove 520 is relatively deep, if the mounting groove 520 is directly provided on the adjusted plate 300, the thickness of the adjusted plate 300 needs to be relatively large, which will result in a relatively heavy weight of the leveling device 1000. In this embodiment, by providing the mounting block 500 and providing the mounting groove 520 on the mounting block 500, it is beneficial to reduce the thickness of the adjusted plate 300, thereby reducing the weight of the leveling device 1000.
[0082] In the present embodiment, the driving member 110 is threadedly connected with the base 200, and the staff can use a wrench or a screwdriver knob to drive the member 110, so that the driving member 110 can move up and down, which is simple to operate and easy to adjust. In other embodiments, the driving member 110 can also be a push rod, and the driving member 110 can be a round rod or a square rod. The staff pushes and pulls the driving member 110 to move the driving member 110 up and down, and after the driving member 110 moves to the appropriate position, the driving member 110 is fixed using a latch. When the driving member 110 is a push rod, the driving member 110 does not need to rotate, and the abutment section 112 of the driving member 110 can be fixedly connected to the adjusted plate 300. Or the abutment section 112 of the driving member 110 can be fixedly connected to the first groove wall surface 521 and the second groove wall surface 522 of the mounting block 500 to achieve that the abutment section 112 of the driving member 110 is indirectly connected to the adjusted plate 300.
[0083] In this embodiment, by providing a plurality of leveling assemblies 100 , the plurality of leveling assemblies 100 can simultaneously level the plate 300 to be adjusted, making the operation more convenient.
[0084] In some embodiments, the stopper 122 is spaced apart from the bottom surface of the receiving cavity 1111, that is, the stopper 122 is spaced apart from the side of the driving member 110 away from the adjusted plate 300. This design can reduce the friction between the driving member 110 and the stopper 122, and when the staff rotates the driving member 110, the driving member 110 is easier to rotate, and the operation is simpler.
