Description

Lens module and locking components

The present invention relates to a locking component, and in particular to a locking component that can be applied to a lens and a lens module using the locking component.

With the development of technology, lens modules are widely used in daily life. Generally speaking, in a digital light processing (DLP) projector, the image is generated by a digital micromirror device (DMD), and for the flatness tolerance size of the lens distance DMD, press The conventional optical design tolerance requirement needs to be less than 0.03 mm. If the machining tolerance of the parts meets the above-mentioned precision production requirements, the machining cost of the parts will increase and the yield rate of the machining parts will be too low. Therefore, the current approach is to use the projector lens Add flatness tolerance value compensation pads or Boresight adjustment structure to achieve the requirements of optimizing the balance of the picture and making the projection picture clear. However, the disadvantage of the former is that the flatness compensation pad cannot be adjusted in real time when projecting images. The disadvantage of the latter is that there is no tangential fillet (R angle) between the adjustment screw of the collimation adjustment structure and the lens connection contact surface. After adjustment or locking, the degree of freedom of lens deflection adjustment is poor, and the lens housing structure is easy to In the case of pulling or pressing, micro-deformation stress occurs. In addition, the conventional method requires the lens to be connected to the accessory plate, and then to be locked with other supporting seat components, so that the parts accumulate and increase the weight, so that the assembled product will fall or shake due to the acceleration of gravity. Due to the physical inertia of the quasi-directional screw, the locking force of the quasi-directional screw is gradually reduced, which increases the risk of loosening, and other accessory components may increase the error of the cumulative tolerance of the assembly. On the other hand, the conventional quasi-directional structural elements are complex and diverse, the device space is large, and different working directions (locking adjustment directions) are required, which is disadvantageous to automatic assembly and automatic adjustment.

Therefore, the directional terms used are used to illustrate and not to limit the creation of the new model.

FIG. 1A is a schematic diagram of a lens module according to an embodiment of the invention. FIG. 1B is a disassembled diagram of the lens module of FIG. 1A. In order to make the drawings clearer, FIG. 1A and FIG. 1B only show a part of the carrier 110. 1A and 1B, the lens module 100A of this embodiment includes a carrier 110, a lens 120, at least one locking component 130, and at least one elastic member 140. The lens 120 has at least one locking portion 121, and the locking portion 121 has a through hole 1211. The locking assembly 130 includes a first locking accessory 131 and a second locking accessory 132. Here, the elastic member 140 is, for example, a spring, the first locking attachment 131 is, for example, a bolt, and the second locking attachment 132 is, for example, a nut.

In this embodiment, the first locking attachment 131 has a first external thread 1311 and a second external thread 1312, and the pitch of the first external thread 1311 is different from that of the second external thread 1312. The second locking attachment 132 has a first internal thread 1322. The first lock attachment 131 is adapted to pass through the through hole 1211 and be locked to the carrier 110 by the first external thread 1311, and the first lock attachment 131 and the second lock attachment 132 are adapted to pass through the second external thread 1312 and the first An internal thread 1322 is locked to each other, so that the locking portion 121 is limited between the second locking accessory 132 and the carrier 110 as shown in FIG. 1B.

FIG. 1C is a schematic top view of the lens module of FIG. 1A. In fact, the carrier 110 surrounds the lens 120 as shown in FIG. 1C and forms a space for the lens 120 to be placed. To make the drawing clearer, the lens 120 of FIG. 1A is only partially shown in FIG. 1C. In this embodiment, the number of the locking components 130 is three, and it reaches three points into one plane. In other embodiments, the number of the locking components can also be adjusted so that the lens can be well fixed to the carrier. The creation of this new type is not correct. This is restricted.

In this embodiment, the number of elastic members 140 corresponds to the number of locking components 130. FIG. 1D is a schematic partial cross-sectional view of the lens module of FIG. 1A. In this embodiment, the elastic member 140 is disposed between the carrier 110 and the locking portion 121 and is in a compressed state so as to be suitable for pushing the locking portion 121 toward the second locking attachment 132. Here, the elastic member 140 is, for example, sleeved on the carrier 110, but it is not limited thereto.

Under the above configuration, the first locking accessory 131 is fastened to the carrier 110, and the locking torque is greater than that of the second locking accessory 132. After the through hole 1211 and the elastic member 140 are penetrated by the first locking attachment 131, the second locking attachment 132 pre-locks the lens 120 to the pre-locking position. Therefore, the gap GA can be adjusted by an appropriate tool. The adjustment method is for example: a. The second lock attachment 132 is locked in the negative X direction. b. The bearing surface of the carrier 110 is in contact with the reference surface of the locking portion 121 of the lens 120 and is set as the initial point of adjustment. c. The center of the second lock attachment 132 is close to and coincides with the center of the through hole 1211. d. The elastic member 140 applies stress in the positive X direction to press the lens 120 tightly on the mating surface of the second lock attachment 132. Here, the stress applied by the elastic member 140 only needs to load the reaction force generated by the weight of the lens 120. e. The lens module 100A includes three locking components 130, that is, the lens 120 has three adjustment points, and each adjustment point is not easy to go to X, Y under the two forces of the negative X direction and the positive X direction. , Z-direction displacement, causing focus shift.

The model of the first external thread 1311 is, for example, M3, and the pitch (Pitch) is 0.5 mm, which is defined as the coarse tooth area and is Right-hand thread. The model of the second external thread 1312 is, for example, M2.6, and the pitch (Pitch) is 0.45 mm, which is defined as a fine pitch area and is a left-handed thread. The first internal thread 1322 of the second locking attachment 132 is, for example, a left-hand thread. Generally speaking, the operation of right-handed thread is that when turning to the right, the thread will advance, and turning to the left will return the thread, while the left-hand thread is the opposite.

In other words, the first external thread 1311 (coarse-tooth area) and the second external thread 1312 (fine-tooth area) of the first locking accessory 131 of this embodiment have opposite rotating spirals, and the first internal thread 1322 of the second locking accessory 132 It has the same rotating thread as the second external thread 1312 (fine tooth area), but the creation of the new type does not impose restrictions on this.

Under the above configuration, the micro-adjustment method can include three stages. The first stage is, for example, the first lock attachment 131 and the second lock attachment 132 rotate in a first rotation direction (for example, clockwise, right-handed) synchronously. , In the first segment, the lens 120 is moved about 0.5 mm in the negative X direction. The second segment is, for example, that the second lock attachment 132 independently rotates one turn in a second rotation direction (for example, counterclockwise, left-handed) opposite to the first rotation direction, and moves along the first lock attachment 131 toward the carrier 110, the first The lock attachment 131 does not rotate, and the lens 120 moves about 0.45 mm in the negative X direction in the second segment. For example, the third segment is that the first lock attachment 131 is rotated in the first rotation direction (for example, clockwise, right) for one turn, and the second lock attachment 132 does not rotate, that is, the first lock attachment 131 is relative to the second lock attachment 132. And the through-hole 1211 rotates, the first lock attachment 131 enters a circle and the second lock attachment 132 enters a circle. In the third segment, the lens 120 moves in the negative X direction incrementally by about 0.95 mm (0.5 mm plus 0.45 mm) . If the adjustment stroke of the lens 120 is long, the lens 120 can be accelerated to reach the preset adjustment positioning point, and then the first segment or the second segment can be used for detailed adjustment.

In this way, the pitch of the first external thread 1311 of the first locking component 131 of the locking assembly 130 is different from the pitch of the second external thread 1312, so that the first locking component 131, the second locking component 132, or the two It can produce different displacement strokes relative to the carrier 110 during the rotation and screwing process, and can have a variety of combinations, according to which the distance between the lens 120 and the carrier 110 can be fine-tuned, and it can be adjusted at multiple points at the same time. It will rotate in the opposite direction, and will not cause mutual restraint or interference.

More specifically, referring to FIG. 1D, one end of the second lock attachment 132 has an arc surface 1321, and the arc surface 1321 is suitable for contacting the lock attachment portion 121. The first locking attachment 131 is suitable for passing through the through hole 1211, and the arc surface 1321 is suitable for abutting against an end of the through hole 1211. Therefore, the contact surface between the second locking accessory 132 and the locking portion 121 of the lens 120 has rounded corners, and the second locking accessory 132 and the lens 120 are in line contact. This design method is in contact with the existing locking screw and the lens. Compared with the surface contact, the locking assembly 130 of this embodiment can achieve a better degree of freedom in adjusting the tilt of the lens. When the housing structure of the lens 120 is pulled or pressed, it is less likely to produce micro-deformation stress.

In the first segment, the lens 120 is moved about 0.45 mm in the negative X direction. The second stage is, for example, that the second lock attachment 132B alone rotates in the first rotation direction (for example, clockwise, right-handed) and moves along the first lock attachment 131B toward the carrier 110B, and the first lock attachment 131B does not rotate. In the second segment, the lens 120 is moved about 0.5 mm in the negative X direction. The third segment is, for example, the first lock attachment 131B alone rotates in the first rotation direction (for example, clockwise, right rotation) for 1 turn, the second lock attachment 132B does not rotate, and the lens 120 moves in the X direction by about 0.05 mm (0.45 mm).

In other embodiments, the dispensing groove can also be configured in the locking assembly of any of the foregoing embodiments in an appropriate manner, and the invention of the present invention does not limit this.

In summary, the embodiments of the present invention have at least one of the following advantages or effects. The pitch of the first external thread of the first locking accessory of the locking assembly is different from the pitch of the second external thread, so that the first locking accessory, the second locking accessory, or both can be synchronized in the process of rotating and screwing. It produces different displacement strokes relative to the carrier, and can have a variety of collocations, according to which the distance between the lens and the carrier can be fine-tuned. The assembly parts of the lens module created by the new model are simplified, and the accumulated tolerance can be reduced, so the quality of the projection image can be effectively adjusted.

Or, the second lock attachment has a dispensing slot that can accommodate a large amount of glue, and the amount of glue is better controlled so that the glue will not be scattered. The method of locking and attaching the lens module created by the new model can simplify the requirements for the operation direction of the equipment for automatic assembly and automatic adjustment. Moreover, the multi-stage micro-adjustment screw structure does not need to greatly reduce the pitch and special processing custom threads to achieve the effect of fine-tuning the pitch, and the size requires a variety of options.
