[0002] Before printing printed circuit boards, the thickness of the boards needs to be measured, typically using a through-beam laser sensor. A through-beam laser sensor consists of two components: a transmitter and a receiver.

[0038] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are intended only to describe specific embodiments and are not intended to limit this application.

[0039] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0040] First, see Figure 1 The present embodiment provides a mounting adjustment mechanism 100, which includes a locking block 1, a first locking member a1, a movable block 2, and a first abutting block 3. The first locking member a1 is used to lock the locking block 1 to an external device. The movable block 2 is rotatably connected to the locking block 1. The movable block 2 is used to mount a sensor body 201. The first abutting block 3 is used to limit the rotation angle of the movable block 2 relative to the locking block 1, thereby mounting the sensor body 201 to the external device.

[0041] For the above locking block 1, see Figures 1 to 3 The locking block 1 has a plurality of first holes 11 extending through the locking block 1 along a first direction X. The first holes 11 extend along a second direction Y, and the plurality of first holes 11 are spaced apart along a third direction Z. A first locking member a1 passes through the first hole 11 and connects to an external device to lock the locking block 1 to the external device. For example, the external device has a screw hole, and the first locking member a1 is a screw. The first locking member a1 passes through the first hole 11 and is threadedly connected to the external device through the screw hole of the external device, thereby pressing the locking block 1 against the external device, i.e., fixing it to the external device. When the first locking member a1 is loosened, the first locking member a1 releases the locking block 1. When the plurality of first locking members a1 are loosened, the locking block 1 can move along the second direction Y relative to the external device, and the locking block 1 can rotate about the first direction X relative to the external device. Therefore, the position of the locking block 1 relative to the external device along the second direction Y can be adjusted, and the rotation angle of the locking block 1 relative to the external device about the first direction X can be adjusted. Optionally, the number of the first holes 11 is two, and the first holes 11 are waist-shaped holes.

[0042] It should be noted that, in the embodiment of the present application, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In other embodiments, the first direction X, the second direction Y, and the third direction Z may also form an obtuse angle or an acute angle between each other.

[0043] For Activity Block 2 above, see Figures 1 to 3 , the movable block 2 is rotatably connected to the locking block 1, and the rotation axis of the movable block 2 is parallel to the second direction Y. Specifically, the locking block 1 is provided with a second hole 12, and the second hole 12 passes through the locking block 1 along the second direction Y; the installation and adjustment mechanism 100 also includes a first fastener a2, the first fastener a2 passes through the second hole 12 and is connected to the movable block 2, and the first fastener a2 is used to rotate relative to the locking block 1 to rotatably connect the movable block 2 to the locking block 1. Exemplarily, the central axis of the second hole 12 is parallel to the second direction Y, the first fastener a2 is a screw, the movable block 2 is provided with a connecting hole 21, and the connecting hole 21 is a screw hole. The first fastener a2 passes through the second hole 12 and is threadedly connected to the movable block 2 through the connecting hole 21. The first fastener a2 is in a loose state relative to the locking block 1, so that the movable block 2 is rotatably connected to the locking block 1, and the rotation axis of the movable block 2 is parallel to the second direction Y. Furthermore, when the movable block 2 is rotatably connected to the locking block 1 via the first fastener a2 , the movable block 2 can rotate about the third direction Z relative to the locking block 1 .

[0044] It should be noted that an unconstrained spatial rigid body has six degrees of freedom: translational freedom along three mutually perpendicular directions and rotational freedom about these three directions. Adjustment freedom refers to the degrees of freedom by which an object can be adjusted relative to its mounting base. For example, in the embodiment of the present application, the sensor body 201 can be adjusted relative to an external device by translation along the second direction Y and by rotational freedom about the first direction X, the second direction Y, and the third direction Z. Therefore, the sensor body 201 in the embodiment of the present application has four adjustment degrees of freedom relative to the external device, reducing the difficulty of adjusting the orientation of the sensor body 201.

[0045] In some embodiments, see Figures 1 to 3The locking block 1 is provided with a third hole 13, which is spaced from the rotation axis of the movable block 2. The third hole 13 extends through the locking block 1 along the second direction Y and along the first direction X. The installation and adjustment mechanism 100 also includes a second locking member a3, which passes through the third hole 13 and connects to the movable block 2 to lock the rotation angle of the movable block 2 relative to the locking block 1. Exemplarily, the central axis of the third hole 13 is parallel to the second direction Y. The second locking member a3 is a screw. The movable block 2 is provided with a connecting hole 21, which is a threaded hole. The second locking member a3 passes through the third hole 13 and is threadedly connected to the movable block 2 via the connecting hole 21. When the second locking member a3 is loosened, the movable block 2 can rotate relative to the locking block 1. When the second locking member a3 is tightened, the second locking member a3 prevents the movable block 2 from rotating relative to the locking block 1, thereby locking the rotation angle of the movable block 2 relative to the locking block 1. Optionally, the third hole 13 is a waist-shaped hole or an arc-shaped hole.

[0046] In some embodiments, see Figures 1 to 3 The movable block 2 is provided with a plurality of first adjustment members a4, which are abutted against an external device along a first direction X. The first adjustment members a4 are used to adjust the length of the first adjustment members a4 extending from the movable block 2 when the movable block 2 rotates relative to the movable block 2, so as to adjust the rotation angle of the movable block 2 relative to the locking block 1. Exemplarily, the movable block 2 is provided with a fourth hole 22, which passes through the movable block 2 along the first direction X. The fourth hole 22 is a screw hole, and the first adjustment member a4 is a screw. The first adjustment member a4 is threadedly connected to the movable block 2 through the fourth hole 22. Thus, when the first adjustment member a4 rotates, the length of the first adjustment member a4 extending from the movable block 2 changes. Since the first adjustment member a4 abuts against the external device, the rotation angle of the movable block 2 relative to the external device and the locking block 1 changes, that is, by rotating the first adjustment member a4, the rotation angle of the movable block 2 relative to the locking block 1 can be adjusted. Adjustment by rotating the screw facilitates fine-tuning of the rotation angle of the movable block 2 relative to the locking block 1.

[0047] Adjusting the rotation angle of the movable block 2 relative to the locking block 1 includes adjusting the rotation angle of the movable block 2 relative to the locking block 1 in the second direction Y and the third direction Z. Before adjusting the first adjusting member a4, first loosen the first fastener a2 and the second locking member a3. At this point, the movable block 2 can rotate relative to the locking block 1 in both the second direction Y and the third direction Z. Then, rotate the first adjusting member a4 to fine-tune the rotation angle of the movable block 2 relative to the locking block 1. Finally, tighten the first fastener a2 and the second locking member a3.

[0048] In some embodiments, see Figures 1 to 3, viewed along the first direction X, at least one first adjusting member a4 coincides with the rotation axis of the movable block 2, at least two first adjusting members a4 are spaced apart from the rotation axis of the movable block 2, and at least two first adjusting members a4 are spaced apart in a direction parallel to the rotation axis of the movable block 2. For example, see Figure 2 The number of the fourth holes 22 is three, and the three fourth holes 22 and the one second hole 12 are respectively arranged adjacent to the four corners of the movable block 2, and one fourth hole 22 intersects the central axis of the second hole 12. Figure 2 As shown in the example, rotating the first adjustment members a4 installed in the two fourth holes 22 on the right side adjusts the rotation angle of the movable block 2 relative to the locking block 1 about the second direction Y. Rotating the first adjustment members a4 installed in the two fourth holes 22 on the bottom side adjusts the rotation angle of the movable block 2 relative to the locking block 1 about the third direction Z. The three first adjustment members a4 allow the rotation angle of the movable block 2 relative to the external device to be adjusted in two directions, thereby increasing the degree of adjustment freedom of the sensor body 201 relative to the external device. Furthermore, the movable block 2 is more stably supported when abutted against the external device by the three first adjustment members a4. That is, the rotation angles of the movable block 2 and the sensor body 201 relative to the external device are more stable after the rotation angles are adjusted.

[0049] In some embodiments, see Figures 1 to 3 The movable block 2 is provided with a plurality of fifth holes 23 on a side facing away from the external device. The fifth holes 23 are used to connect the movable block 2 to the sensor body 201. Exemplarily, the fifth holes 23 are screw holes, and the sensor body 201 is provided with a first mounting hole 2011. A screw passes through the first mounting hole 2011 and is threadedly connected to the movable block 2 through the fifth holes 23, thereby pressing the sensor body 201 against the movable block 2, i.e., installing it on the movable block 2. When there are multiple fifth holes 23, the sensor body 201 is correspondingly provided with multiple first mounting holes 2011, so that the sensor body 201 can be mounted on the movable block 2 using multiple screws, thereby enhancing the stability of the sensor body 201 installed on the movable block 2.

[0050] Furthermore, the plurality of fifth holes 23 form a rotationally symmetrical figure, and the axis of rotational symmetry is parallel to the first direction X. It should be noted that if a new figure obtained by rotating a plane figure around a point on the plane by a certain angle completely coincides with the original figure, the plane figure is called a rotationally symmetrical figure, and its axis of rotation is the axis of rotational symmetry. Therefore, when the plurality of fifth holes 23 are rotated by a certain angle around an axis parallel to the first direction X, the plurality of fifth holes 23 coincide with the plurality of fifth holes 23 before rotation, so that the sensor body 201 can be mounted on the movable block 2 at at least two angles. For example, please refer to Figure 2 and Figure 3There are two fifth holes 23, and an axis parallel to the first direction X is located at the midpoint between the two fifth holes 23. After the two fifth holes 23 are rotated 180 degrees about this axis, the two rotated fifth holes 23 overlap with the two fifth holes 23 before rotation. Thus, the sensor body 201 can be mounted on the movable block 2 at two different angles, with the mounting directions differing by 180 degrees. It is understood that when there are two or more fifth holes 23, a rotationally symmetrical pattern can also be formed, such as three fifth holes 23 arranged in an equilateral triangle, or four fifth holes 23 arranged in a rectangular shape.

[0051] For the first abutment block 3, see Figures 1 to 3 The first abutting block 3 is used to be set on an external device. The first abutting block 3 is provided with an elastic abutting member a5. The elastic abutting member a5 abuts against the end of the movable block 2 away from the locking block 1 to drive the first adjusting member a4 to abut against the external device. For example, the first abutting block 3 is provided with a sixth hole 31. The sixth hole 31 passes through the first abutting block 3 along the second direction Y; the elastic abutting member a5 is installed on the first abutting block 3 through the sixth hole 31, and the front end of the elastic abutting member a5 abuts against the movable block 2. Moreover, along the first direction X, the distance between the central axis of the sixth hole 31 and the external device is smaller than the distance between the central axis of the second hole 12 and the external device, that is, the elastic abutting member a5 is closer to the external device than the first fastener a2, so that the elastic abutting member a5 applies a torque to the movable block 2 to rotate toward the external device, so that the first adjusting member a4 abuts against the external device. The elastic force of the elastic abutment a5 causes the first adjusting member a4 to abut against the external device, allowing the movable block 2 to move relative to the external device in the second direction Y and to rotate relative to the external device about the first direction X and the third direction Z. This means that the movement and rotation of the movable block 2 are not hindered, and the elastic force always acts on the movable block 2. Optionally, the elastic abutment a5 is a ball screw with a spherical front end, which helps reduce friction between the movable block 2 and the elastic abutment a5.

[0052] See also Figure 2 and Figure 3 The first abutting block 3 is provided with a second mounting hole 32, which penetrates the first abutting block 3 along the first direction X. The second mounting hole 32 is used for a screw to pass through to mount the first abutting block 3 to an external device. Optionally, the number of the second mounting holes 32 is two.

[0053] The elastic abutment a5 is used to adjust the length of the elastic abutment a5 extending from the first abutment block 3 when the elastic abutment a5 rotates relative to the first abutment block 3. Exemplarily, the sixth hole 31 is a screw hole, and the elastic abutment a5 is a ball screw. The elastic abutment a5 is threadedly connected to the first abutment block 3 through the sixth hole 31, so that when the elastic abutment a5 is rotated, the length of the elastic abutment a5 extending from the first abutment block 3 can be adjusted. By adjusting the length of the elastic abutment a5 extending from the first abutment block 3, the magnitude of the elastic force of the elastic abutment a5 on the movable block 2 can be adjusted, and the elastic force can be synchronously adjusted according to the distance adjusted along the second direction Y of the locking block 1 relative to the external device, so that the elastic force of the elastic abutment a5 on the movable block 2 is within a suitable range.

[0054] In some embodiments, see Figures 1 to 3 , at least two elastic abutting members a5 are spaced apart along the third direction Z. Exemplarily, the second abutting block 4 is provided with two sixth holes 31, the two sixth holes 31 are spaced apart along the third direction Z, and the two elastic abutting members a5 are respectively threadedly connected to the second abutting block 4 through the two sixth holes 31. It can be understood that when the locking block 1 rotates around the first direction X relative to the external device, the direction of the elastic force of the elastic abutting member a5 on the movable block 2 is not directly facing the locking block 1, and the elastic force will apply a torque to the locking block 1, and the torque has a tendency to restore the locking block 1 to the state before it rotated around the first direction X relative to the external device, for example Figure 1 In the embodiment, after the locking block 1 and the movable block 2 are rotated counterclockwise relative to the external device, the elastic abutment a5 will apply a clockwise torque to the locking block 1 and the movable block 2, resulting in a large resistance when the locking block 1 rotates relative to the external device in the first direction X, making rotation difficult, and unstable and easy to recover after rotation. In this embodiment, the length of the two elastic abutment a5 extending from the first abutment can be adjusted accordingly according to the rotation angle of the locking block 1 relative to the external device in the first direction X, for example Figure 1 In the embodiment, after the locking block 1 and the movable block 2 are rotated counterclockwise relative to the external device, the elastic supporting member a5 on the right side can be extended toward the movable block 2 for an adjusted distance, so that the torque applied by the two elastic supporting members a5 to the locking block 1 and the movable block 2 is reduced or even becomes zero.

[0055] In some embodiments, see Figures 1 to 3The installation adjustment mechanism 100 also includes a second abutting block 4, which is used to be set on an external device. The second abutting block 4 is provided with a plurality of second adjusting members a6, which abut against the side of the locking block 1 away from the movable block 2 to adjust the position of the locking block 1 relative to the external device along the second direction Y. Exemplarily, the second abutting block 4 is provided with a seventh hole 41, which passes through the second abutting block 4 along the second direction Y. The seventh hole 41 is a screw hole, and the second adjusting member a6 is a screw. The second adjusting member a6 is threadedly connected to the second abutting block 4 through the seventh hole 41. Therefore, when the second adjusting member a6 rotates, the length of the second adjusting member a6 extending from the second abutting block 4 changes. Since the second adjusting member a6 abuts against the locking block 1, the position of the locking block 1 relative to the external device along the second direction Y can be adjusted by the second adjusting member a6 after the first locking member a1 is loosened. Adjustment is performed by rotating the screw, which facilitates fine-tuning the position of the movable block 2 relative to the external device.

[0056] See also Figure 2 and Figure 3 The second abutting block 4 is provided with a third mounting hole 42, which penetrates the second abutting block 4 along the first direction X. The third mounting hole 42 is used for a screw to pass through to mount the second abutting block 4 to an external device. Optionally, there are two third mounting holes 42.

[0057] In some embodiments, see Figures 1 to 3 , at least two second adjustment members a6 are spaced apart along the third direction Z. Exemplarily, the second abutting block 4 is provided with two seventh holes 41, the two seventh holes 41 are spaced apart along the third direction Z, and the two second adjustment members a6 are respectively threadedly connected to the second abutting block 4 through the two seventh holes 41. When the two second adjustment members a6 rotate synchronously, the lengths of the two second adjustment members a6 extending from the second abutting block 4 change in the same manner to adjust the position of the locking block 1 relative to the external device along the second direction Y; when the two second adjustment members a6 rotate asynchronously, the lengths of the two second adjustment members a6 extending from the second abutting block 4 change in different manners to adjust the rotation angle of the locking block 1 relative to the external device around the first direction X.

[0058] Second, see Figures 1 to 3 The present embodiment provides a sensor device 200, comprising a sensor body 201 and a mounting and adjustment mechanism 100 as described above; the sensor body 201 is disposed on the movable block 2. The sensor device 200 possesses the structural features and beneficial effects of the mounting and adjustment mechanism 100, which will not be further described here. It should be understood that the mounting and adjustment mechanism 100 is not limited to mounting the sensor body 201 but can also be used to mount other electronic or mechanical components that require adjustable rotation angle and position, such as cameras and laser emitters.

[0059] Thirdly, please refer to Figure 4 , an embodiment of the present application provides a printer 300, the printer 300 includes a bracket 301 and a sensor device 200, and the sensor device 200 is arranged on the bracket 301. The printer 300 has the structural features and beneficial effects of the installation adjustment mechanism 100, which will not be repeated here. It should be noted that the printer 300 in the embodiment of the present application is a PCB (Printed Circuit Board) printer 300. The PCB printer 300 is a printer 300 that utilizes the characteristics of laser ablation to ablate the coating pre-covered on the surface of the PCB according to the negative film of the PCB, thereby retaining the positive film as a semi-finished product before corrosion. It can be understood that the sensor device 200 is not limited to being installed on the bracket 301 of the printer 300, but can also be installed on other auxiliary devices, such as a feeding device, a unloading device, a conveying device, etc.
