The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] Reference below Figure 1-Figure 9 The alignment device 100 for assembling a workpiece 400 according to an embodiment of the present invention is described. The alignment device 100 is disposed in an automatic assembly system 1000 , and the alignment device 100 is used to align the assembly position of the workpiece 400 .

[0040] According to the first embodiment of the utility model, the alignment device 100 for assembling a workpiece 400 is as follows: Figure 1-Figure 3 As shown, the alignment device 100 may include: a mounting frame 10, a driving member 20, an alignment portion 30, an elastic member 40 and a displacement detection member 50. The driving member 20 is arranged on the mounting frame 10. The alignment portion 30 is connected to the driving member 20. The alignment portion 30 is suitable for abutting against the workpiece 400. The driving member 20 is used to drive the alignment portion 30 to move toward or away from the workpiece 400. Along the moving direction of the alignment portion 30, the alignment portion 30 is movable relative to the driving member 20. The elastic member 40 is located between the driving member 20 and the alignment portion 30. The elastic member 40 is suitable for driving the alignment portion 30 to move away from the driving member 20. The displacement detection member 50 is used to detect the displacement of the alignment portion 30 relative to the driving member 20.

[0041] It should be noted that in the related art, when assembling the automobile steering gear, the steering gear rack needs to be rotated to a suitable angle before installation. However, in the automated assembly process, a robot grabs the rack and assembles it into the steering gear housing. Existing robots cannot ensure that the rack is rotated to a suitable position before assembling the rack, and the rack cannot automatically find the assembly position during the installation process.

[0042] Based on this, the embodiment of the present application proposes a alignment device 100, including: a mounting frame 10, a driving member 20, an alignment part 30, an elastic member 40 and a displacement detection member 50, the driving member 20 is arranged on the mounting frame 10, the mounting frame 10 can be fixedly connected with the driving member 20, for example, the driving member 20 can be connected with the mounting frame 10 by welding, bolting, etc., the mounting frame 10 can be used to support the driving member 20, the alignment part 30 is connected with the driving member 20, the alignment part 30 can be connected with the driving member 20 by a shaft and a bearing matching assembly connection mode, the alignment part 30 is suitable for abutting with a workpiece 400, and the alignment device 100 realizes the assembly position of the workpiece 400 by the alignment part 30 abutting with the workpiece 400. The driving member 20 can drive the alignment part 30 to move toward or away from the workpiece 400, and along the moving direction of the alignment part 30, the alignment part 30 is movable relative to the driving member 20, and the alignment part 30 can move relative to the driving member 20. An elastic member 40 is provided between the driving member 20 and the alignment part 30. The elastic member 40 can be constructed as a spring, a spring sheet, etc. The elastic member 40 can be compressed. The elastic member 40 is compressed to generate an elastic driving force. The elastic member 40 stores energy. The elastic member 40 can drive the alignment part 30 to move away from the driving member 20. A displacement detection member 50 is also provided between the alignment part 30 and the driving member 20. The displacement detection member 50 is used to detect the displacement of the alignment part 30 relative to the driving member 20. The displacement detection member 50 can record the value of the displacement of the alignment part 30 relative to the driving member 20.

[0043] The alignment device 100 can be used to align the assembly position of the steering gear rack (i.e., the workpiece 400) during assembly. Figure 4 As shown, the rack can be constructed as a rod with a tooth structure 410. The embodiment of the present application is described by taking the workpiece 400 as an example of a rack. Taking the rack as an example, when the alignment part 30 abuts against the tooth structure 410, the alignment device 100 aligns the assembly position of the workpiece 400.

[0044] As an example, when the alignment device 100 is working, the driving member 20 can drive the alignment part 30 to move in a direction away from the driving member 20, and the alignment part 30 abuts against the workpiece 400, so that the alignment part 30 moves in a direction close to the driving member 20, and the elastic member 40 is compressed. At this time, the elastic member 40 generates an elastic driving force, and the displacement detection member 50 detects the displacement of the alignment part 30 relative to the driving member 20 and records the value of the relative displacement, and then rotates the workpiece 400. When the displacement detection member 50 detects that the displacement of the alignment part 30 relative to the driving member 20 is unchanged, it indicates that the alignment device 100 has not aligned the assembly position of the workpiece 400, and the workpiece 400 continues to be rotated. When the displacement detection member 50 detects that the displacement of the alignment part 30 relative to the driving member 20 is reduced, it indicates that the alignment device 100 has aligned the assembly position of the workpiece 400, and the subsequent assembly work can be completed. When the displacement detecting member 50 detects that the displacement of the alignment part 30 relative to the driving member 20 increases, it indicates that the initial position where the alignment device 100 abuts against the workpiece 400 is the assembly position of the workpiece 400. The workpiece 400 continues to be rotated. When the displacement detecting member 50 detects that the displacement of the alignment part 30 relative to the driving member 20 decreases, it indicates that the alignment device 100 has aligned the assembly position of the workpiece 400, and the subsequent assembly work can be completed.

[0045] As another example, a pressure sensor may be provided on the driving member 20, and the driving member 20 may drive the alignment part 30 to move in a direction away from the driving member 20. The alignment part 30 abuts against the workpiece 400, so that the elastic part 40 located between the driving member 20 and the alignment part 30 is compressed. At this time, the elastic part 40 generates an elastic driving force. When the pressure sensor detects that the elastic part 40 generates an elastic driving force, the driving member 20 stops driving the alignment part 30 to move, and the elastic part 40 stores energy. The displacement detection part 50 detects the displacement of the alignment part 30 relative to the driving member 20 and records the value of the relative displacement. The workpiece 400 rotates, and the displacement detection part 50 continues to detect the displacement of the alignment part 30 relative to the driving member 20 and records the value of the relative displacement. During the rotation of the workpiece 400, the displacement detection part 50 continuously records the value of the relative displacement between the alignment part 30 and the driving member 20. When the alignment device 100 does not align the assembly position of the workpiece 400, the alignment part 30 is always in contact with the workpiece 400, and the value of the relative displacement between the alignment part 30 and the driving member 20 does not change. When the alignment device 100 aligns the assembly position of the workpiece 400, the elastic member 40 releases energy, and the elastic member 40 drives the alignment part 30 to move away from the driving member 20. At this time, the displacement detection member 50 detects the relative displacement between the alignment part 30 and the driving member 20 and records the value of the relative displacement. The relative displacement value between the alignment part 30 and the driving member 20 decreases, indicating that the alignment device 100 aligns the assembly position of the rack, and the assembly position of the workpiece 400 can be determined by the change in the value of the relative displacement between the alignment part 30 and the driving member 20.

[0046] In the embodiment of the present application, the relative displacement between the alignment part 30 and the driving member 20 is detected by the displacement detection member 50, so that the assembly position of the workpiece 400 can be aligned, the workpiece 400 can be installed smoothly, and it is beneficial to improve the assembly efficiency of the workpiece 400.

[0047] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the driving member 20 may include: a main body 21 and a moving part 22, the main body 21 is fixed to the mounting frame 10, the main body 21 and the moving part 22 are connected, the moving part 22 is movable relative to the main body 21, the alignment part 30 is movably arranged on the moving part 22, the main body 21 is used to drive the moving part 22 to move along the moving direction of the alignment part 30 so that the alignment part 30 moves toward or away from the workpiece 400, and the elastic member 40 is located between the moving part 22 and the alignment part 30.

[0048] The driving member 20 may include a main body 21 and a moving part 22. The main body 21 is fixed to the mounting frame 10. The main body 21 may be fixedly connected to the mounting frame 10 by means of a clamping connection, a bolt connection, etc. The main body 21 is connected to the moving part 22. The moving part 22 may move relative to the main body 21. As an example, the main body 21 may be formed with a slide rail and a driving part, and the driving part is connected to the moving part 22 to drive the moving part 22 to slide along the slide rail. As another example, the driving member 20 may be configured as a push cylinder, and the moving part 22 may be pushed out relative to the main body 21 to achieve movement of the moving part 22 relative to the main body 21.

[0049] The alignment part 30 can move together with the moving part 22, and the alignment part 30 can move relative to the moving part 22. The alignment part 30 is movably arranged on the moving part 22. When the main body 21 drives the moving part 22 to move along the moving direction of the alignment part 30, the movement of the moving part 22 can drive the alignment part 30 to move together, so that the driving member 20 drives the alignment part 30 to move toward the workpiece 400 to achieve the effect of the alignment part 30 abutting against the workpiece 400. When the alignment part 30 abuts against the workpiece 400, the elastic member 40 is compressed, and the elastic member 40 generates an elastic driving force. When the workpiece 400 rotates to the assembly position, the elastic member 40 can drive the alignment part 30 to move relative to the moving part 22 away from the moving part. The alignment device 100 can drive the alignment part 30 to move through the moving part 22, so that the alignment part 30 is away from the driving part 20, thereby achieving the abutment effect between the alignment part 30 and the workpiece 400. During the rotation of the workpiece 400, the elastic part 40 can drive the alignment part 30 to move to achieve the assembly position of the alignment workpiece 400.

[0050] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the driving member 20 may further include: a guide shaft 60 , the moving portion 22 is formed with a guide hole 221 , the guide shaft 60 is passed through the guide hole 221 and is fixedly connected to the alignment portion 30 .

[0051] The driving member 20 may further include a guide shaft 60. A guide hole 221 is formed on the moving part 22 along the moving direction of the alignment part 30. The guide shaft 60 is inserted into the guide hole 221. The guide shaft 60 can move along the axial direction of the guide hole 221. The guide shaft 60 is fixedly connected to the alignment part 30. The guide shaft 60 can be connected to the alignment part 30 by means of clamping, bolt connection, etc. The alignment part 30 can achieve relative movement with the moving part 22 through the guide shaft 60. By setting the guide shaft 60 to be inserted into the guide hole 221, the guide shaft 60 can guide the alignment part 30, so that the alignment part 30 can move relative to the moving part 22 along the axial direction of the guide hole 221. There can be multiple guide shafts 60, and there can also be multiple guide holes 221. The multiple guide shafts 60 and the multiple guide holes 221 correspond to each other one by one. By setting multiple guide shafts 60 and multiple guide holes 221, it is beneficial to improve the stability of the movement of the alignment part 30 and the stability of the alignment device 100.

The guide shaft 60 moves along the axial direction of the guide hole 221, which can compress the elastic member 40 or release the elastic member 40. The elastic member 40 is sleeved on the guide shaft 60, making the structure of the alignment device 100 more compact.

[0054] In some embodiments of the present invention, Figure 3 As shown, a linear bearing 222 is provided at the guide hole 221, and the linear bearing 222 is sleeved on the guide shaft 60. The linear bearing 222 can be assembled with the guide shaft 60, and the guide shaft 60 can move relative to the linear bearing 222. By providing the linear bearing 222, the guide shaft 60 can move smoothly along the axial direction of the guide hole 221, which helps to achieve the movement of the alignment part 30 relative to the moving part 22. In addition, the linear bearing 222 can also reduce the friction of the guide shaft 60 in linear motion, improve the working efficiency of the alignment device 100, and extend the service life of the alignment device 100.

The limit piece 61 is located on the side of the moving part 22 away from the alignment part 30. The limit piece 61 cannot be inserted into the guide hole 221. The limit piece 61 can abut against the side wall of the moving part 22 away from the alignment part 30 for limitation. The limit piece 61 can limit the guide shaft 60. The limit piece 61 can limit the guide shaft 60 from moving out of the guide hole 221, thereby reducing the risk of the guide shaft 60 being disengaged from the guide hole 221 and improving the safety of the alignment device 100.

[0060] Along the moving direction of the alignment part 30, the moving part 22 forms an installation space 223 opposite to the alignment part 30, and the installation space 223 can be set between two adjacent guide shafts 60. The displacement detection component 50 is fixed to the moving part 22, and part of the displacement detection component 50 is assembled in the installation space 223. The displacement detection component 50 is provided with a moving detection part 51, and the moving detection part 51 abuts against the alignment part 30. The moving detection part 51 can detect the displacement of the alignment part 30 relative to the moving part 22, so that the displacement detection component 50 can detect the relative displacement of the moving part 22 and the alignment part 30, thereby achieving the effect of determining the assembly position of the workpiece 400 by comparing the change in the relative displacement between the moving part 22 and the alignment part 30.

[0061] According to the second aspect of the present invention, an automatic assembly system 1000 for assembling a workpiece 400 is provided.

[0062] The automatic assembly system 1000 may include: a clamping device 300, a supporting device 200, an alignment device 100 and a control device. The clamping device 300 is used to clamp the workpiece 400. The clamping device 300 can move toward the adapter 500. The clamping device 300 can clamp the workpiece 400 and thereby drive the workpiece 400 to move toward the adapter 500, thereby achieving the effect that the clamping device 300 drives the workpiece 400 to move toward the adapter 500. The clamping device 300 can also rotate. The clamping device 300 can clamp the workpiece 400 and thereby drive the workpiece 400 to rotate together, thereby achieving the effect that the clamping device 300 drives the workpiece 400 to rotate. By setting the clamping device 300, the working stability of the automatic assembly system 1000 can be improved.

[0063] The support device 200 is used to support the workpiece 400. The support device 200 may be provided with a lifting assembly 210 and a lifting bracket 220. The lifting bracket 220 is provided with a supporting wheel 230. The support device 200 is provided below the workpiece 400. When the alignment device 100 is in the process of aligning the assembly position of the workpiece 400, the lifting assembly 210 drives the lifting bracket 220 to rise, and the supporting wheel 230 abuts against the workpiece 400, and the support device 200 plays a role in supporting the workpiece 400. After the alignment device 100 aligns the assembly position of the workpiece 400, the clamping device 300 drives the workpiece 400 to move toward the adapter 500. When the workpiece 400 is away from the clamping device 300 and one end of the workpiece 400 is assembled with the adapter 500, the lifting assembly 210 drives the lifting bracket 220 to descend, thereby reducing the risk of collision between the support device 200 and the clamping device 300.

[0064] The alignment device 100 is the alignment device 100 of the above embodiment. The alignment device 100 can align the assembly position of the workpiece 400 to ensure that the workpiece 400 is located in the correct installation direction, so that the workpiece 400 can be installed smoothly, which is beneficial to improving the assembly efficiency of the workpiece 400.

During the automatic assembly process of the workpiece 400, the control device controls the clamping device 300 to work, the clamping device 300 clamps the workpiece 400, and the clamping device 300 drives the workpiece 400 to rotate. At this time, the control device drives the supporting device 200 to work, the lifting bracket 220 on the supporting device 200 rises, and the supporting wheel 230 supports the workpiece 400.

[0066] At the same time, the control device controls the alignment device 100 to work, the driving member 20 can drive the alignment part 30 to move in the direction away from the driving member 20, the alignment part 30 abuts against the workpiece 400, so that the alignment part 30 moves toward the driving member 20, and the elastic member 40 is compressed. At this time, the elastic member 40 generates an elastic driving force until the moving part 22 is fully extended. The elastic force of the elastic member 40 pushes the alignment part 30 to abut against the workpiece, and the displacement detection member 50 detects the displacement of the alignment part 30 relative to the driving member 20 and records the value of the relative displacement, and then rotates the workpiece 400. If the displacement detection member 50 detects that the displacement of the alignment part 30 relative to the driving member 20 is unchanged, it indicates that the alignment device 100 has not aligned the assembly position of the workpiece 400, and the workpiece 400 continues to be rotated. When the displacement detection member 50 detects that the displacement of the alignment part 30 relative to the driving member 20 is reduced, it indicates that the alignment device 100 has aligned the assembly position of the workpiece 400, and the subsequent assembly work can be completed. If the displacement detecting part 50 detects that the displacement of the alignment part 30 relative to the driving part 20 increases, it indicates that the initial position where the alignment device 100 abuts against the workpiece 400 is the assembly position of the workpiece 400. The workpiece 400 continues to be rotated. When the displacement detecting part 50 detects that the displacement of the alignment part 30 relative to the driving part 20 decreases, it indicates that the alignment device 100 has aligned the assembly position of the workpiece 400, and the subsequent assembly work can be completed.

[0067] After the alignment device 100 aligns the assembly position of the workpiece 400, the control device controls the moving part 22 of the alignment device 100 to drive the alignment part 30 to move in a direction away from the workpiece 400, thereby reducing the risk of collision between the alignment part 30 and the clamping device 300. The clamping device 300 drives the workpiece 400 to move toward the adapter 500. When the end of the workpiece 400 away from the clamping device 300 is assembled with the adapter 500, the control device controls the support device 200 to retract, thereby reducing the risk of collision between the clamping device 300 and the support device 200. The clamping device 300 continues to drive the workpiece 400 to move toward the adapter 500. When the workpiece 400 and the adapter 500 are assembled, the clamping device 300 releases the workpiece 400, and the control device controls the clamping device 300, the supporting device 200 and the alignment device 100 to return to the initial position, so that the clamping device 300, the supporting device 200 and the alignment device 100 can prepare for the alignment and assembly position of the next workpiece 400. By setting the control device, the automatic alignment function of the workpiece 400 can be realized, and the automatic assembly of the workpiece 400 can be realized.

The lifting assembly 210 may be connected to the lifting bracket 220 by means of clamping, bolt connection, etc. The lifting assembly 210 may drive the lifting bracket 220 to rise and fall. When the support device 200 supports the workpiece 400, the lifting bracket 220 rises. When the support bracket no longer supports the workpiece 400, the lifting bracket 220 falls. The lifting bracket 220 is provided with a support wheel 230. The support wheel 230 may be formed with an assembly hole. The assembly hole passes through the support wheel 230. The mounting pin may be penetrated through the support wheel 230. The support wheel 230 may be rotatably arranged on the lifting bracket 220 through the mounting pin.
