[0032] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.
[0033] This application discloses a voice coil motor module 100; please refer to [link / reference needed]. Figure 1 and Figure 2 ,like Figure 1 and Figure 2 As shown, the voice coil motor module 100 may include a base assembly 10, a motion assembly 20, a voice coil motor 30, and a guide rail assembly 40.
[0034] The base assembly 10 may include a first mounting bracket 11, and the motion assembly 20 may include a second mounting bracket 21. The voice coil motor 30 may include a mover 31 and a stator 32. The stator 32 may be connected to the first mounting bracket 11, and the mover 31 may be connected to the second mounting bracket 21. The voice coil motor 30 may be used to drive the motion assembly 20 to move relative to the base assembly 10.
[0035] For example, the stator 32 of the voice coil motor 30 can be detachably connected to the first mounting bracket 11, and the mover 31 of the voice coil motor 30 can be detachably connected to the second mounting bracket 21. The voice coil motor 30 can be used to drive the motion component 20 to reciprocate in the vertical direction relative to the base component 10.
[0036] Furthermore, the guide rail assembly 40 may include a plurality of cross roller guide rails 41, and the guide rail assembly 40 may be correspondingly disposed between the base assembly 10 and the motion assembly 20 for limiting the motion assembly 20 in the motion direction of the voice coil motor 30.
[0037] For example, the cross roller guide 41 may include a guide member 42 and a retainer 43, one of which is disposed on a first mounting bracket 11 and the other is disposed on a second mounting bracket 21. The guide member 42 and the retainer 43 cooperate with each other and can be used to limit the motion component 20 in the motion direction of the voice coil motor 30.
[0038] Furthermore, the plurality of crossed roller guides 41 may be symmetrically arranged relative to the voice coil motor 30, and the plurality of crossed roller guides 41 may include crossed roller guides or crossed ball guides.
[0039] Furthermore, the base assembly 10 may also include two first side plates 13, and the motion assembly 20 may also include two second side plates 23. The two first side plates 13 are detachably connected to both ends of the first mounting plate, and the two second side plates 23 are detachably connected to both ends of the second mounting plate. The first gap between the two first side plates 13 is greater than the second gap between the two second side plates 23, and a third gap is left between each first side plate 13 and the corresponding second side plate 23.
[0040] It is understandable that the first side plate 13 and the second side plate 23 are correspondingly arranged. Using the third gap, one of the guide rail 42 and the cage 43 can be arranged on the first side plate 13 and the other can be arranged on the second side plate 23, so that the guide rail 42 and the cage 43 cooperate accordingly to limit the motion component 20 in the motion direction of the voice coil motor 30.
[0041] For further details, please refer to Figure 3 ,like Figure 3 As shown, the cross roller guide 41 may include at least one guide member 42 and two retainers 43. The two retainers 43 respectively cooperate with the two sides of the guide member 42, thereby enhancing the load capacity, guiding ability and durability of the cross roller guide 41.
[0042] It is understood that the cross roller guide 41 may also include at least two guide rails 42 and a retainer 43. Rollers are provided on both sides of the retainer 43. By having the two guide rails 42 cooperate with the two sides of the retainer 43 respectively, the load capacity, guiding ability and durability of the cross roller guide 41 can be enhanced.
[0043] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 ,like Figure 4 As shown, the voice coil motor module 100 may also include multiple load balancing components 50. Each load balancing component 50 may include a guide 51 and a spring 52.
[0044] For example, such as Figure 1 , Figure 3 and Figure 4 As shown, the guide 51 can be adjusted to pass through the second mounting bracket 21, and the spring 52 can be set on the first mounting bracket 11. The spring 52 and the guide 51 are positioned corresponding to each other. The spring 52 uses its own elastic force to act on the guide 51, thereby balancing the gravity of the second mounting bracket 21 and its load. Multiple load balancing components are symmetrically arranged relative to the voice coil motor 30.
[0045] For example, such as Figure 1 and Figure 3 As shown, the second mounting bracket 21 may be provided with a threaded through hole 54, and the side plates on both sides of the first mounting bracket 11 may be provided with holes 53. The guide 51 may include a Class C fully threaded hexagonal head bolt, which is adjustablely inserted into the second mounting bracket 21 through the threaded through hole 54. The spring 52 may be set in the hole 53, and the hole 53 may be used as a sleeve to fit around the spring 52, ensuring the stable operation of the load balancing assembly 50.
[0046] It is understandable that by using the hole 53 in the first side plate 13 as a sleeve for the spring 52, it is not necessary to set a separate spring 52 sleeve on the first mounting bracket 11, making the overall voice coil motor module 100 more compact in structure, which is conducive to saving materials and miniaturizing equipment to adapt to different processes and site environments.
[0047] It can be further understood that the user can control the compression or extension of the spring 52 by adjusting the threaded connection between the guide 51 and the second mounting bracket 21, thereby making better use of the load balancing assembly 50 to balance the weight of the load on the second mounting plate.
[0048] In some embodiments, the base assembly 10 may further include a limiting member 12. The second mounting bracket 21 may be provided with a limiting guide groove 22 along the movement direction of the voice coil motor 30. The limiting member 12 may be connected to the first mounting bracket 11. The limiting member 12 can pass through the limiting guide groove 22 and move within the limiting guide groove 22.
[0049] For example, the limiting member 12 can be connected to the first side plate 13, and the limiting guide groove 22 can be correspondingly disposed on the second side plate 23. The limiting member 12 can pass through the limiting guide groove 22 and move within the limiting guide groove 22.
[0050] The limiting component 12 may include a spring 52 shock absorber, anti-collision rubber, magnetic shock absorber or air flotation shock absorber.
[0051] Understandably, the design of the limiting member 12 and the limiting guide groove 22 can limit the movement direction and stroke of the moving component 20 relative to the base component 10, and at the same time reduce the collision impact that may be caused when the moving component 20 travels to the end of the stroke, thereby avoiding equipment damage or personal injury.
[0052] In some embodiments, the voice coil motor module 100 may further include a displacement measuring component 60 for measuring the displacement of the motion component 20 relative to the base component 10.
[0053] For example, the displacement measurement assembly 60 may include an encoder 61 and a scale 62, one of which may be disposed on a first mounting bracket 11 and the other may be disposed on a second mounting bracket 21, with the encoder 61 and the scale 62 being disposed correspondingly.
[0054] Furthermore, the displacement measuring component 60 may also include a photoelectric switch 63 and a sensing plate 64, one of which is disposed on the first mounting bracket 11 and the other is disposed on the second mounting bracket 21, and the photoelectric switch 63 and the sensing plate 64 are disposed correspondingly.
[0055] It is understandable that closed-loop control can be achieved through the encoder 61 and grating 62 in the displacement measurement component 60. Through the photoelectric switch 63 and sensing plate 64, the displacement measurement component 60 can easily find the zero point or the maximum stroke point, thereby improving the positioning accuracy or repeatability of the voice coil motor module 100 and improving the performance, stability and safety of the equipment.
[0056] In some embodiments, the motion component 20 may further include a pressure sensor, which may be disposed on the second mounting bracket 21.
[0057] In some embodiments, the voice coil motor module 100 may further include a pressure sensor, which may be disposed on the voice coil motor 30.
[0058] Understandably, through the pressure sensor, the voice coil motor module 100 can control the force of the load, thus enabling it to be applied to industrial and commercial scenarios that require force control, such as precision assembly of electronic circuits and precision processing of chip substrates, thereby improving the versatility of the product.
[0059] Please see Figure 5 ,like Figure 5 As shown, this application also proposes a alignment and correction platform 200. The alignment and correction platform 200 may include a voice coil motor module 100 as described in any embodiment of this application. The alignment and correction platform 200 may be a novel multi-axis correction platform.
[0060] Furthermore, the alignment and correction platform 200 may also include an alignment platform 210 and an angle turntable 220, with the angle turntable 220 mounted on the alignment platform 210 and the voice coil motor module 100 mounted on the angle turntable 220.
[0061] For example, the voice coil motor module 100 can also be mounted on the angle turntable 220 via the adapter plate 230.
[0062] Without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.
[0063] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
