Description
Technical Field
[0001] The present invention relates to the technical field of laser galvanometers, and in particular to an installation tool and an installation method. Background Art
[0002] The galvanometer motor is an excellent vector scanning device and is currently mainly used in laser equipment, such as laser marking machines, laser drilling machines and laser radars. Its main application features are high-speed and high-precision operation to meet the use functions of the application products.
[0003] The function of the galvanometer motor is to make the lens holder swing left and right around a center line during operation, and it is necessary to ensure that the swing angles of the lens holder on both sides of the center line are consistent.
[0004] When assembling the galvanometer motor and the lens bracket, the existing process flow is to first fix the housing of the galvanometer motor and the winding of the galvanometer motor with glue, then press the vibrator of the galvanometer motor and the lens bracket together, and finally install the vibrator into the housing.
[0005] Ideally, the center line is positioned based on the outer shell. The direction of the magnetic field generated by the winding needs to be perpendicular to the center line, and the direction of the magnetic field of the vibrator needs to be consistent with the opening on the lens holder, so as to achieve the purpose of consistent swing angles of the lens holder on both sides of the center line.
[0006] However, in order to ensure that there is no cogging effect between the vibrator and the stator (including the housing and winding) of the galvanometer motor, the inner surface of the housing needs to be set as a smooth cylindrical surface. In this case, there are no cogging on the inner surface of the housing to control the position of the winding in the circumferential direction, and there will be a certain angle error between the direction of the magnetic field generated by the winding and the center line due to winding shape deviation, insufficient housing processing accuracy, insufficient installation accuracy, etc.
[0007] In addition, when the vibrator and the lens holder are pressed together, due to insufficient positioning accuracy of the magnetic field direction of the vibrator, a certain angle error may exist between the magnetic field direction of the vibrator and the opening direction of the lens holder.
[0008] The above two errors are superimposed to form a larger cumulative error, resulting in inconsistent swing angles of the lens bracket on both sides of the center line when the galvanometer motor is running, resulting in defective products. Summary of the invention

[0015] The second positioning component includes two positioning pins, both of the two positioning pins are arranged on the first base and correspond to the two mounting holes, and the positioning pins are in plug-in fit with the corresponding mounting holes.

[0017] The second positioning component further includes a first elastic member, and the first elastic member abuts against one end of the positioning pin away from the corresponding mounting hole.
[0018] As a further optional solution for the installation tooling, the first positioning component includes a positioning block, the positioning block is arranged on the first base along the connection line of the two positioning pins, and the positioning block is used for engaging with the opening of the lens bracket.

[0020] As a further optional solution for the installation tooling, the first positioning component is further used to carry the lens bracket;
[0021] The installation tooling further includes a second base, and the second base is used to abut against the vibrator of the galvanometer motor.
[0022] As a further optional solution for the installation tooling, a holding member and a third elastic member are arranged on the second base;

[0027] Another object of the present invention is to provide an installation method.
[0028] The present invention provides the following technical solutions:

[0033] The embodiments of the present invention have the following beneficial effects:
[0034] When assembling the galvanometer motor and the lens holder using the above installation tooling, the winding of the galvanometer motor is powered by a DC power supply to generate a magnetic field. The oscillator of the galvanometer motor rotates under the influence of this magnetic field until the magnetic field direction of the oscillator itself is the same as the direction of this magnetic field.

[0035] During the working process, when the oscillator is at the zero position, the magnetic field direction of the oscillator itself is perpendicular to the magnetic field direction generated by the winding, and the opening direction of the lens holder coincides with the center line of the housing. The changing magnetic field generated by the winding drives the oscillator to rotate back and forth around the zero position, thereby driving the lens holder to swing back and forth around the center line.
[0036] At this time, regardless of whether the magnetic field direction generated by the winding is perpendicular to the center line, and regardless of whether the magnetic field direction of the oscillator itself coincides with the opening direction of the lens holder, the swing angles of the lens holder on both sides of the center line are not affected, thereby eliminating the assembly angle error between the housing and the winding, and also eliminating the assembly angle error between the oscillator and the lens holder. It can reduce the cumulative error when assembling the galvanometer motor and the lens holder, and is beneficial to making the swing angles of the lens holder on both sides of the center line the same.

[0054] Embodiment 1
[0055] Please refer to Figure 1 and Figure 2 together. This embodiment provides an installation tooling for assembling a galvanometer motor 10 and a lens holder 20. The installation tooling includes a first base 100 and a DC power supply 200.
[0056] Please combine with Figure 3 . The first base 100 has a first positioning component 110 and a second positioning component 120. The first positioning component 110 is used to position the lens holder 20, and the second positioning component 120 is used to position the housing 11 of the galvanometer motor 10 so that the center line of the housing 11 is perpendicular to the opening direction of the lens holder 20.
[0057] Wherein, the center line is a virtual line that coincides with a certain diameter line of the housing 11 and is defined according to product requirements.
[0058] In addition, the DC power supply 200 is used to supply power to the winding 12 of the galvanometer motor 10.
[0059] When assembling the galvanometer motor 10 and the lens holder 20 using the above installation tooling, the DC power supply 200 is used to supply power to the winding 12 of the galvanometer motor 10 to generate a magnetic field. The vibrator 13 of the galvanometer motor 10 rotates under the influence of this magnetic field until the magnetic field direction of the vibrator 13 itself is the same as the direction of this magnetic field. At the same time, the first positioning component 110 is used to position the lens holder 20, and the second positioning component 120 is used to position the housing 11 of the galvanometer motor 10 so that the center line of the housing 11 is perpendicular to the opening direction of the lens holder 20. On this basis, the vibrator 13 and the lens holder 20 can be assembled together.
[0060] During the working process, when the vibrator 13 is at the zero position, the magnetic field direction of the vibrator 13 itself is perpendicular to the magnetic field direction generated by the winding 12, and the opening direction of the lens holder 20 coincides with the center line of the housing 11. The changing magnetic field generated by the winding 12 drives the vibrator 13 to rotate back and forth around the zero position, thereby driving the lens holder 20 to swing back and forth around the center line.
[0061] At this time, regardless of whether the magnetic field direction generated by the winding 12 is perpendicular to the center line, and regardless of whether the magnetic field direction of the oscillator 13 itself coincides with the opening direction of the lens holder 20, the swing angles of the lens holder 20 on both sides of the center line are not affected, thereby eliminating the assembly angle error between the housing 11 and the winding 12, and also eliminating the assembly angle error between the oscillator 13 and the lens holder 20. It can reduce the cumulative error when assembling the galvanometer motor 10 and the lens holder 20, which is beneficial to making the swing angles of the lens holder 20 on both sides of the center line the same.
[0062] In some embodiments, the first positioning component 110 is further configured to carry the lens holder 20. That is, the lens holder 20 is placed on the first positioning component 110 from top to bottom and is positioned by the first positioning component 110.
[0063] Correspondingly, the above-mentioned installation tooling further includes a second base 300, and the second base 300 is used to abut against the oscillator 13.
[0064] When assembling the oscillator 13 and the lens holder 20, the second base 300 is located above the first base 100. By bringing the second base 300 and the first base 100 closer to each other, the oscillator 13 can be pressed into the lens holder 20.
[0065] In other embodiments, the first base 100 can also be used to carry the galvanometer motor 10, and the second base 300 is used to abut against the lens holder 20 to press-fit the lens holder 20 and the oscillator 13 together.
[0066] Please refer to Figure 4 , further, a abutting member 310 and a third elastic member 320 are provided on the second base 300.
[0067] Among them, the abutting member 310 slidably penetrates through the second base 300. One end of the abutting member 310 abuts against the third elastic member 320, and the other end of the abutting member 310 is used to abut against the oscillator 13.
[0068] When the abutting member 310 abuts against the oscillator 13 and the second base 300 and the first base 100 are brought closer to each other, the reaction force exerted by the oscillator 13 on the abutting member 310 overcomes the elastic force of the third elastic member 320, causing the abutting member 310 to slide relative to the second base 300. During this process, the abutting member 310 and the second base 300 are elastically connected, and the pressure between the abutting member 310 and the oscillator 13 gradually increases, and it is not easy to damage the oscillator 13 or the lens holder 20.
[0069] Further, a flange 311 is provided on the side wall of the abutting member 310 near one end of the vibrator 13. When the abutting member 310 slides relative to the second base 300 until the flange 311 contacts the second base 300, a rigid connection is formed between the abutting member 310 and the second base 300, ensuring that the abutting member 310 can apply sufficient pressure to the vibrator 13 to press the vibrator 13 into the lens holder 20.
[0070] In addition, a limiting groove 330 is formed on the second base 300, and the limiting groove 330 is arranged along the sliding direction of the abutting member 310. A limiting rod 312 is provided on the abutting member 310, and the limiting rod 312 is in sliding fit with the limiting groove 330.
[0071] During use, the limiting rod 312 slides relative to the second base 300 along with the abutting member 310, while preventing the abutting member 310 from completely detaching from the second base 300.
[0072] Please refer again to Figure 2 and Figure 3 , in some embodiments, the above installation tooling further includes a first template 400 and a second template 500. The first template 400 and the second template 500 are in sliding fit, and the direction of relative sliding between the first template 400 and the second template 500 is parallel to the direction in which the vibrator 13 is pressed into the lens holder 20, which is indicated by the Z direction in the figure.
[0073] Among them, the first base 100 is disposed on the surface of the first template 400 facing the second template 500, and the second base 300 is disposed on the surface of the second template 500 facing the first template 400.
[0074] During use, by respectively installing the first template 400 and the second template 500 on a stamping device such as a hand press, it is possible to more labor - savingly press the vibrator 13 into the lens holder 20.
[0075] Optionally, the first template 400 is a fixed mold and remains stationary during the assembly process. The second template 500 is a movable mold and is pressed downward along the Z direction under the drive of the stamping device.
[0076] In some specific embodiments, a guide rod 410 is fixedly provided on the first template 400, and the length direction of the guide rod 410 is parallel to the Z direction. Correspondingly, a linear bearing 510 is fixedly provided on the second template 500, and the linear bearing 510 is slidably sleeved on the guide rod 410 to guide the relative sliding of the first template 400 and the second template 500.
[0077] Further, a first limiting member 420 is provided on the side of the first template 400 facing the second template 500, and a second limiting member 520 is correspondingly provided on the side of the second template 500 facing the first template 400.
[0078] During the process of the first template 400 and the second template 500 sliding towards each other, the first limiting member 420 and the second limiting member 520 approach each other until the first limiting member 420 abuts against the second limiting member 520. At this time, the first template 400 and the second template 500 cannot continue to slide towards each other, thereby restricting the depth of the oscillator 13 being pressed into the lens holder 20.
[0079] Please refer to Figure 5 and Figure 6 In this embodiment, the housing 11 has two mounting holes 11a. The two mounting holes 11a are symmetrically arranged about the axis of the housing 11, and the perpendicular bisector of the line connecting the two mounting holes 11a is the center line.
[0080] Correspondingly, the second positioning assembly 120 includes two positioning pins 121. The two positioning pins 121 are both arranged on the first base 100 and correspond to the two mounting holes 11a. In addition, the positioning pin 121 is in plug-in fit with the corresponding mounting hole 11a.
[0081] During assembly, the mounting hole 11a on the housing 11 is aligned with the corresponding positioning pin 121 and placed in, so as to realize the positioning of the housing 11.
[0082] Optionally, the mounting hole 11a is a threaded hole, and the housing 11 is bolted and fixed to other structures through the threaded hole.
[0083] Furthermore, the positioning pin 121 slides through the first base 100, and the sliding direction of the positioning pin 121 is parallel to the Z direction.
[0084] In addition, the second positioning assembly 120 further includes a first elastic member 122, and the first elastic member 122 abuts against one end of the positioning pin 121 away from the corresponding mounting hole 11a.
[0085] Before the oscillator 13 penetrates into the lens holder 20, the positioning pin 121 has been in plug-in fit with the corresponding mounting hole 11a to position the housing 11. When the oscillator 13 penetrates into the lens holder 20, the housing 11 is pressed down together with the second base 300 and the second template 500, and overcomes the elastic force of the first elastic member 122, so that the positioning pin 121 slides downward relative to the first base 100 along the Z direction. During this process, the positioning pin 121 always positions and guides the housing 11.
[0086] In some embodiments, the first positioning assembly 110 includes a positioning block 111. The positioning block 111 is arranged on the first base 100 along the direction of the line connecting the two positioning pins 121, and the positioning block 111 is used for clamping with the opening of the lens holder 20.
[0087] During assembly, the lens holder 20 is placed on the positioning block 111 with the opening facing downward, and the opening of the lens holder 20 is engaged with the positioning block 111 , so that the positioning of the lens holder 20 is completed.
[0088] Since the positioning block 111 is disposed along the connecting line direction of the two positioning pins 121 , the opening direction of the lens holder 20 coincides with the connecting line direction of the positioning pins 121 and is perpendicular to the center line.
[0089] Optionally, a groove 130 is formed on the first base 100. The positioning block 111 is embedded in the groove 130 and bolted to the first base 100, so as to be firmly connected to the first base 100. When the vibrator 13 is pressed into the lens holder 20, the positioning block 111 can stably support and limit the lens holder 20, so as to prevent the lens holder 20 from deviating from its original position when the force is uneven.
[0090] Furthermore, the first positioning assembly 110 further includes a positioning pin 112 and a second elastic member 113. The positioning pin 112 is slidably disposed on the first base 100 along the Z direction and is used to pass through the lens bracket 20. The second elastic member 113 abuts against an end of the positioning pin 112 away from the galvanometer motor 10.
[0091] Before the vibrator 13 penetrates the lens holder 20, the positioning pin 112 protrudes from the surface of the first base 100 and penetrates the lens holder 20, which can also position the lens holder 20. When the vibrator 13 penetrates the lens holder 20, the vibrator 13 overcomes the elastic force of the second elastic member 113 to make the positioning pin 112 slide downward relative to the first base 100 along the Z direction. After the assembly is completed, as the galvanometer motor 10 and the lens holder 20 are removed, the positioning pin 112 pops out and resets under the elastic force of the second elastic member 113.
[0092] In summary, when the galvanometer motor 10 and the lens holder 20 are assembled using the above-mentioned installation tool, the DC power supply 200 is first used to supply power to the winding 12 of the galvanometer motor 10, so that the winding 12 generates a magnetic field. The vibrator 13 of the galvanometer motor 10 is affected by the magnetic field and rotates until the direction of the magnetic field of the vibrator 13 itself is in the same direction as the direction of the magnetic field. Then the lens holder 20 is sleeved on the positioning pin 112, and the opening of the lens holder 20 is engaged with the positioning block 111. Then the second template 500 is moved to move the second template 500 upward, and the mounting hole 11a of the housing 11 is aligned with the positioning pin 121 and inserted. Then the second template 500 is released, and the second template 500 is pressed down, so that the abutting member 310 abuts against the vibrator 13, and the lower end surface of the vibrator 13 is pre-pressed into the inner hole of the lens holder 20. Finally, the hand press is pulled to continue to press the second template 500 downward to press the vibrator 13 into the lens holder 20.
[0093] When the oscillator 13 is at the zero position, the magnetic field direction of the oscillator 13 itself is perpendicular to the magnetic field direction generated by the winding 12. During the above installation process, the magnetic field direction of the oscillator 13 itself is the same as the magnetic field direction generated by the winding 12. In other words, the oscillator 13 during the installation process rotates 90° compared to the zero position. Similarly, the lens holder 20 during the installation process rotates 90° compared to the zero position, and the opening direction of the lens holder 20 should be perpendicular to the center line of the housing 11 and coincide with the connecting line direction of the two mounting holes 11a.
[0094] On this basis, by positioning the housing 11 with the positioning pins 121 and positioning the lens holder 20 with the positioning block 111 arranged along the connecting line direction of the two positioning pins 121, the purpose that the opening direction of the lens holder 20 coincides with the connecting line direction of the two mounting holes 11a can be achieved.
[0095] Regardless of whether the magnetic field direction generated by the winding 12 is perpendicular to the center line and whether the magnetic field direction of the oscillator 13 itself coincides with the opening direction of the lens holder 20, it will not affect the relative position between the lens holder 20 and the housing 11, thereby eliminating the assembly angle error between the housing 11 and the winding 12 and also eliminating the assembly angle error between the oscillator 13 and the lens holder 20, which can reduce the cumulative error during the assembly of the galvanometer motor 10 and the lens holder 20 and is beneficial to making the swing angles of the lens holder 20 on both sides of the center line the same.
[0096] Embodiment 2
[0097] Please refer to Figure 7 , this embodiment provides an installation method, which is applied to the above installation tooling and is used for assembling the galvanometer motor 10 and the lens holder 20. The installation method includes the following steps:
[0098] S1, supply power to the winding 12 of the galvanometer motor 10 using the DC power supply 200.
[0099] Specifically, after passing direct current, the winding 12 generates a constant magnetic field. The oscillator 13 is affected by this magnetic field and rotates until the magnetic field direction of the oscillator 13 itself is the same as the direction of this magnetic field. At this time, the oscillator 13 rotates 90° compared to the zero position.
[0100] S2, position the housing 11 and the lens holder 20 of the galvanometer motor 10 so that the center line of the housing 11 is perpendicular to the opening direction of the lens holder 20.
[0101] Specifically, align the mounting holes 11a of the housing 11 with the positioning pins 121 and place them to achieve the positioning of the housing 11. Sleeve the lens holder 20 on the positioning pins 112 and make the opening of the lens holder 20 engage with the positioning block 111 to achieve the positioning of the lens holder 20.
[0102] At this time, since the positioning block 111 is arranged along the connection direction of the two positioning pins 121, the opening direction of the lens holder 20 coincides with the connection direction of the two mounting holes 11a and is perpendicular to the center line of the housing 11.
[0103] S3. Assemble the vibrator 13 of the galvanometer motor 10 and the lens holder 20.
[0104] Specifically, press the vibrator 13 downward into the lens holder 20, and the installation of the galvanometer motor 10 and the lens holder 20 can be completed.
[0105] During this process, regardless of whether the magnetic field direction generated by the winding 12 is perpendicular to the center line and regardless of whether the magnetic field direction of the vibrator 13 itself coincides with the opening direction of the lens holder 20, it will not affect the relative position between the lens holder 20 and the housing 11, thus eliminating the assembly angle error between the housing 11 and the winding 12 and also eliminating the assembly angle error between the vibrator 13 and the lens holder 20. It can reduce the cumulative error when assembling the galvanometer motor 10 and the lens holder 20, which is beneficial to making the swing angles of the lens holder 20 on both sides of the center line the same.
[0106] It should be noted that the sequence of steps S1 and S2 above is not limited.
[0107] In all the examples shown and described here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.
[0108] It should be noted that like reference numerals and letters denote like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0109] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
