[0038] The exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not used to exhaust all feasible ways of the present application, nor are they used to limit the scope of the present application.

[0039] The present application provides a centering lens adjustment mounting mechanism and a printing device.

[0040] See Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 The centering lens adjustment mounting mechanism may include a clamping block mounting block 100, a first clamping block 210, a second clamping block 220, an elastic member 400, and a clamping adjustment block 500.

[0041] See Figure 3 The clamping block mounting block 100 may have a clamping block mounting surface 140, and a first guide rail 110 and a second guide rail 120 perpendicular to each other may be provided on the clamping block mounting surface 140. In the direction system composed of the mutually perpendicular X-axis, Y-axis, and Z-axis, the first guide rail 110 extends along the Y-axis, and the second guide rail 120 extends along the X-axis. Of course, the depths of the first guide rail 110 and the second guide rail 120 may be different.

[0042] See Figure 1 、 Figure 5, the first clamping block 210 and the second clamping block 220 are slidably mounted on the first guide rail 110 and can clamp the lens 300 after sliding towards each other. At least one of the first clamping block 210 and the second clamping block 220 includes a first clamping surface 231 and a second clamping surface 232 on the side facing the lens 300. The first clamping surface 231 and the second clamping surface 232 are inclined relative to the clamping block mounting surface 140, so that the first clamping block 210 and the second clamping block 220 can clamp the lens 300 via the first clamping surface 231 and the second clamping surface 232 to achieve a self-centering function. Exemplarily, both clamping blocks can have a first clamping surface 231 and a second clamping surface 232 (detailed later) to clamp the lens in a diamond shape. Or one clamping block can have a first clamping surface 231 and a second clamping surface 232, and the side of the other clamping block facing the lens is formed as a vertical plane.

[0043] See Figure 5 , the elastic member 400 can be disposed between the first clamping block 210 and the second clamping block 220 and pull the first clamping block 210 and the second clamping block 220 towards each other. Exemplarily, the elastic member 400 can be a tension spring.

[0044] See Figure 4 , Figure 5 , the clamping adjustment block 500 can be slidably mounted on the second guide rail 120. The clamping adjustment block 500 includes a contact surface that contacts the first clamping block 210 and / or the second clamping block 220, and this contact surface is an inclined surface (detailed later) that is inclined to the extending direction of the second guide rail 120, so that the distance between the first clamping block 210 and the second clamping block 220 can be adjusted after the clamping adjustment block 500 moves on the second guide rail 120. For example Figure 4 , when the clamping adjustment block 500 moves to the left, the first clamping block 210 and the second clamping block 220 are pushed apart away from each other. When the clamping adjustment block 500 moves to the right, the first clamping block 210 and the second clamping block 220 move towards each other under the action of the elastic member 400.

[0045] In this application, the distance between the two clamping blocks can be adjusted by the clamping adjustment block 500 and the elastic member 400, with less occupied structural space, more compact force conduction, and simple clamping. The first clamping surface 231 and the second clamping surface 232 that are inclined to the clamping block mounting surface 140 enable self-centering while clamping, achieving the effect that the center of the lens 300 is on the center of the clamping mechanism, eliminating the need for re-centering steps every time the lens 300 is replaced.

[0046] For the guide rail, see Figure 3 , Figure 5, in one example, the first guide rail 110 and the second guide rail 120 can be formed as dovetail grooves, and the first clamping block 210, the second clamping block 220, and the clamping adjustment block 500 include dovetail protrusions 510 that are cooperatively arranged in the dovetail grooves. The dovetail form of the cooperation facilitates the positioning of the first clamping block 210, the second clamping block 220, and the clamping adjustment block 500 on the Z-axis.

[0047] Furthermore, referring to Figure 3 , positioning pins can be provided at both ends of the first guide rail 110. When the clamping block presses against the positioning pin, there will be a tactile feedback to prompt the operator to prevent the clamping block from disengaging from the dovetail groove. A positioning pin mounting hole 130 can be provided in the first guide rail 110, and the positioning pin is fixedly arranged in the positioning pin mounting hole 130.

[0048] The positioning pin can be formed as a spring positioning pin with a retractable pin head, which can play a certain role in boundary limit and also facilitate the removal of the clamping block from the first guide rail 110.

[0049] Regarding the clamping block, referring to Figure 5 , in one example, the first clamping block 210 and the second clamping block 220 have the same shape and are symmetrically arranged with respect to the second guide rail 120. The first clamping surface 231 and the second clamping surface 232 can be connected to form a V shape, and the angle between the first clamping surface 231 and the clamping block mounting surface 140 can be equal to the angle between the second clamping surface 232 and the clamping block mounting surface 140. That is, the two clamping blocks can have the same shape, which facilitates synchronous advancement and retraction.

[0050] Furthermore, referring to Figure 5 , in one example, the first clamping surface 231 and the second clamping surface 232 are provided with an anti-slip layer 250, and the anti-slip layer 250 can play an anti-slip role to make the clamping of the lens 300 more stable. The anti-slip layer 250 is, for example, a grid-shaped silicone surface, and its material can also be flexible materials such as nylon and rubber strips to avoid the lens 300 from being bumped and scratched.

[0051] Regarding the clamping adjustment block 500, referring to Figure 4 , the clamping adjustment block 500 includes a first adjustment surface 521 and a second adjustment surface 522. The first adjustment surface 521 and the second adjustment surface 522 form an angle with the extension direction (X-axis direction) of the second guide rail 120 and are symmetric about the extension direction of the second guide rail 120. The first clamping block 210 includes a first clamping block contact surface 241 that fits against the first adjustment surface 521, and the second clamping block 220 includes a second clamping block contact surface 242 that fits against the second adjustment surface 522, so as to realize adjusting the distance between the first clamping block 210 and the second clamping block 220 by moving the clamping adjustment block 500.

[0052] A handle 530 can also be provided at the end of the clamping adjustment block 500 to facilitate operating the movement of the clamping adjustment block 500 in the second guide rail 120.

[0053] The centering lens adjustment and mounting mechanism can also adjust the position of the lens 300 on the X-axis, Y-axis, and Z-axis as a whole, and rotate the lens 300 around the Y-axis. See Figure 1 、 Figure 2 In one example, the centering lens adjustment and mounting mechanism can include a lens adjustment and mounting plate 610, an XZ-axis adjustment platform 620, a Y-axis adjustment platform 630, and a rotating platform 640.

[0054] The XZ-axis adjustment platform 620 includes an XZ-axis adjustment platform first part 621 connected to the lens adjustment and mounting plate 610, an XZ-axis adjustment platform second part 622 capable of moving along the X-axis relative to the XZ-axis adjustment platform first part 621, and an XZ-axis adjustment platform third part 623 capable of moving along the Z-axis relative to the XZ-axis adjustment platform second part 622.

[0055] The Y-axis adjustment platform 630 includes a Y-axis adjustment platform first part 631 connected to the XZ-axis adjustment platform third part 623 and a Y-axis adjustment platform second part 632 capable of moving along the Y-axis relative to the Y-axis adjustment platform first part 631.

[0056] See Figure 6 The rotating platform 640 includes a rotating platform first part 641 connected to the Y-axis adjustment platform second part 632 (connected through a second sliding table connecting plate 652, which will be introduced later) and a rotating platform second part 642 capable of rotating around the Y-axis relative to the rotating platform first part 641. The clamping block mounting block 100 is connected to the rotating platform second part 642.

[0057] Further, see Figure 2 and Figure 6 The centering lens adjustment and mounting mechanism can include a first sliding table connecting plate 651 and a second sliding table connecting plate 652. The Y-axis adjustment platform first part 631 can be connected to the XZ-axis adjustment platform third part 623 through the first sliding table connecting plate 651. The first sliding table connecting plate 651 can include two perpendicular plate-like structures, and reinforcing ribs can be provided in the middle. The rotating platform first part 641 is connected to the Y-axis adjustment platform second part 632 through the second sliding table connecting plate 652. The second sliding table connecting plate 652 can include a long strip-shaped chute, and the rotating platform first part 641 can be bolted to the long strip-shaped chute.

[0058] Further, see Figure 2, the aforementioned XZ-axis adjustment platform 620, Y-axis adjustment platform 630, and rotation platform 640 may respectively include differential head knobs 710 and locking screws 720 to enable fine adjustment and locking of movements in various directions. The platforms for fine adjustment on the X, Y, and Z axes and the rotation platform 640 that can be controlled to adjust the rotation angle can all be adjustment platforms in the prior art, and will not be elaborated one by one in this application.

[0059] The centering lens adjustment and installation mechanism may further include a mechanism installation base plate 800, which is used to be installed on an external device. For example, countersunk holes can be provided and connected to relevant components of the printing device through bolts.

[0060] Furthermore, a plurality of long strip chutes 810 can be provided on the mechanism installation base plate 800, for example, four are arranged at intervals along the Z-axis. The lens adjustment and installation plate 610 can be connected (such as by bolts) to the long strip chutes 810. The lens adjustment and installation plate 610 can be installed according to the required height and position of the lens 300.

[0061] Furthermore, an axial positioning structure 310 and a circumferential positioning structure (not shown in the figure) can be provided in the radial direction of the lens 300 to facilitate the positioning and clamping of the lens 300. The axial positioning structure 310 can be formed as a flange, and the circumferential positioning structure can be formed as a plane on the circumferential surface of the lens 300 that is shape-matched with the first clamping surface 231 and the second clamping surface 232.

[0062] The advantages of the centering lens adjustment and installation mechanism provided by this application include:

[0063] 1. The clamping and adjustment method of the lens 300 is simple. Press the clamping adjustment block forward, and the clamping adjustment block pushes the first clamping block 210 and the second clamping block 220 to both sides, causing the clamping blocks to open to a suitable size, and place the lens 300 in place from the opening. After the position of the lens 300 is determined, remove the force pressing the clamping adjustment block. Under the pulling force of the elastic member 400, the clamping blocks on both sides will move closer to the middle and clamp the lens 300 to ensure the stable installation and clamping of the lens 300.

[0064] 2. The position adjustment method of the lens 300 is simple. The design of the lens adjustment and installation plate 610, XZ-axis adjustment platform 620, Y-axis adjustment platform 630, and rotation platform 640 provided by this application facilitates the adjustment of the position of the lens 300, expands the scope of use, and can be compatible with more combinations of lens 300 models and sizes.

[0065] 3. The positioning of the lens 300 is accurate. This application has a self-centering function, the lens 300 is installed stably, and the observation efficiency of the lens 300 can be improved.

[0066] The present application also provides a printing device, which includes the aforementioned centering lens adjustment and mounting mechanism.

[0067] The above are the preferred embodiments of the present application. It should be noted that for those skilled in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
