Description
Technical Field
[0001] This utility model belongs to the field of component position correction, and in particular relates to a multi-dimensional adjustment device. Background Technology
[0002] Through-beam sensors are devices that detect objects by changing the optical path. They have a wide range of applications, one of which is thickness detection on production lines. Specifically, through-beam sensors are placed on the production line to detect the thickness of the current object and determine whether the material meets the production specifications.
[0003] When installing a through-beam sensor, the transmitting end and the reflecting end need to be placed on opposite sides of the production line. When an object passes by, the transmitting end needs to determine whether the current material is the target material by whether it receives a feedback signal from the reflecting end. During installation, in order to ensure that the signal emitted by the transmitting end can be projected onto the target area of the reflecting end, when the signal is visible light, the transmitting end needs to be corrected in three dimensions: left and right deflection, up and down deflection, and vertical movement. The installation is determined by the point where the visible light is projected onto the target area of the reflecting end.
[0004] The current method of installing the reflector is fixed. After the transmitter position is initially calibrated, it is fixed to the production line with screws or bolts. After a certain period of use, the signal emitted by the transmitter may be deviated due to environmental vibrations, or when it is necessary to adapt to different material thicknesses, the position of the transmitter needs to be calibrated in three directions: up and down deflection, left and right deflection, and vertical movement. At this time, the fixed installation method requires the operator to move the position of the transmitter in the relevant dimensions. Since the position of the transmitter is floating and not fixed during the calibration process, it is easy to cause excessive adjustment, making it difficult to accurately project the signal onto the reflector. This increases the difficulty of transmitter position calibration and greatly reduces production efficiency. Utility Model Content
[0005] The multi-dimensional adjustment device provided by this utility model aims to solve the problem of low production efficiency caused by the difficulty in adjusting the target object in the prior art.

[0027] A third elastic element is disposed between the first rotating seat and the second rotating seat. The third elastic element provides a preload force to the second rotating seat to return it to its original position when the second adjusting member removes the pushing force on the second rotating seat.

When the preload is a pushing force, the first rotating seat is also provided with a third blind hole at the position corresponding to the third elastic element, and the second rotating seat is provided with a fourth blind hole corresponding to the third blind hole. The two ends of the third elastic element are respectively placed in the third blind hole and the fourth blind hole.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0042] See Figure 1This embodiment of the invention provides a multi-dimensional adjustment device 100, used to adjust the emitting end 200 of a through-beam sensor so that the visible light emitted by the emitting end 200 can be accurately projected onto the target area of the reflecting end 300. Furthermore, a material conveying platform 400 is provided between the emitting end 200 and the reflecting end 300. The thickness of the material on the conveying platform 400 is adjustable. Therefore, during use, the emitting end 200 also needs to be adaptively adjusted in height according to different material thicknesses using the multi-dimensional adjustment device 100 to prevent the visible light emitted by the emitting end 200 from being constantly blocked by the material when fixed at the same height, thus losing the purpose of detecting target parameters (including but not limited to material thickness). In one application scenario of this embodiment, the through-beam sensor is used to detect the current material thickness on the conveying platform 400, thereby reminding the operator to adjust the parameters required for the production of materials of different specifications in a timely manner. In actual production, the transmitting end 200 and the reflecting end 300 are positioned on opposite sides of the conveying platform 400. Visible light emitted from the transmitting end 200 is projected onto the reflecting end 300, which then reflects the signal back to the transmitting end 200. Visible light includes, but is not limited to, red, green, and blue light, as well as laser light. During use, for the same material thickness, the beam emitted from the transmitting end 200 can be projected onto the target area of the reflecting end 300. The reflecting end 300 then feeds the signal back to the transmitting end 200. When the transmitting end 200 receives the feedback signal from the reflecting end 300, it indicates that the current material thickness on the conveying platform 400 meets production requirements. When the beam emitted from the transmitting end 200 is blocked, and the transmitting end 200 does not receive the feedback signal from the reflecting end 300, it indicates that the current material on the conveying platform 400 has been replaced with a material of a new thickness. This prompts personnel to adjust the production parameters after the material change and simultaneously adjust the vertical height of the transmitting end 200 to adapt to normal equipment operation, achieving the purpose of thickness detection and alerting.
[0043] See Figures 2-3 Specifically, the multi-dimensional adjustment device 100 includes a mounting component 1, a lifting assembly 2, a connecting seat 3, a first rotating seat 4, a first adjustment assembly 5, a second rotating seat 6, and a second adjustment assembly 7. The mounting component 1 is fixed to one side of the conveying platform 400. The lifting assembly 2 is fixed to the mounting component 1. The connecting seat 3 is fixed to the lifting end of the lifting assembly 2 and is driven to lift by the lifting assembly 2. The first rotating seat 4 is rotatably mounted on the connecting seat 3 in a first direction. The first adjustment assembly 5 is located between the connecting seat 3 and the first rotating seat 4 to adjust the rotation of the first rotating seat 4 in the first direction. The second rotating seat 6 is rotatably mounted on the first rotating seat 4 in a second direction, which is perpendicular to the first direction. The transmitting end 200 is fixed to the second rotating seat 6. The second adjustment assembly 7 is located between the first rotating seat 4 and the second rotating seat 6 to adjust the rotation of the second rotating seat 6 in the second direction.
[0044] By fixing the transmitter 200 of the through-beam sensor to the second rotating base 6 and driving the second rotating base 6 to rotate in the second direction using the second adjustment component 7, the transmitter 200 can be adjusted in the second direction. The second rotating base 6 is rotatably mounted on the first rotating base 4 and the first adjustment component 51 drives the first rotating base 4 to rotate in the first direction. The first rotating base 4 can drive the second rotating base 6 to rotate in the first direction, thus enabling the transmitter 200 to be adjusted in the first direction. The first rotating base 4 is rotatably mounted on the connecting base 3, and the connecting base 3 is fixed to the lifting end of the lifting component 2. The lifting component 2 can drive the first rotating base 4 to rise and fall through the connecting base 3, thereby enabling the transmitter 200 to be adjusted in the vertical direction. This allows for position adjustment of the transmitter 200 in three directions, thus enabling precise and convenient projection of the visible light emitted by the transmitter 200 onto the target area of the reflector 300.
[0045] The multi-dimensional adjustment device 100 provided by this utility model adjusts the emitting end 200 by rotating around the center in both the first and second directions. During adjustment, there is no need to change the coordinate position of the emitting end 200 on the plane. It can accurately and quickly project the visible light emitted by the emitting end 200 onto the target area of the reflecting end 300, reducing the difficulty of adjustment and improving the adjustment accuracy. At the same time, it can also adjust the emitting end 200 in the vertical height, which can adapt to the target parameter detection needs of different production environments. The synchronous adjustment of the emitting end 200 in three dimensions has high adjustment accuracy, high adjustment efficiency, and wide applicability.
[0046] See Figure 2 Specifically, the lifting assembly 2 includes a slide rail 21, a slider 22, a connector 23, and a first elastic element 24. The slide rail 21 is vertically mounted on the mounting component 1. The slider 22 cooperates with the slide rail 21. The connecting seat 3 is fixed to the slider 22. The connector 23 is located above the connecting seat 3. One end of the connector 23 is threaded to the connecting seat 3, and the other end passes through the mounting component 1 and abuts against the mounting component 1. Specifically, the end of the connector 23 that passes through the mounting component 1 may have an external locking part 231. The locking part 231 abuts against the surface of the mounting component 1. When the connector 23 is rotated, the connecting seat 3 drives the slider 22 to move on the slide rail 21. The first elastic element 24 is sleeved on the connector 23 and provides a downward preload to the connecting seat 3. Thus, the connecting member 23 can drive the connecting seat 3 to move the slider 22 on the slide rail 21. That is, by rotating the connecting member 23, the connecting seat 3 can move up and down along the thread direction of the connecting member 23 and can remain in the current position after moving. The first elastic member 24 can prevent the fit gap between the connecting member 23 and the connecting seat 3 from bouncing up and down when subjected to external force. This ensures that the slider 22 can stably remain in the current position after moving the transmitter 200 in the vertical direction, thereby improving the accuracy of adjusting the transmitter 200 in the vertical direction.
[0047] In this embodiment, the connector 23 may be threaded in the part that engages with the slider 22, or it may be a screw.
[0048] See Figure 2 Furthermore, the connecting seat 3 is provided with a first clearance groove 31, and the connecting member 23 passes through the connecting seat 3 and extends into the first clearance groove 31. The first clearance groove 31 can prevent the contact area between the connecting member 23 and the connecting seat 3 from being too large, and reduce the resistance generated when the connecting member 23 rotates in the connecting seat 3.
[0049] See Figure 2 , Figure 4 Specifically, the first adjustment assembly 5 includes a first adjustment member 51 and a second elastic member 52. The first adjustment member 51 passes through the connecting seat 3 and abuts against the first rotating seat 4. The first adjustment member 51 can push the first rotating seat 4 to rotate around its rotation center in a first direction. The second elastic member 52 is disposed between the connecting seat 3 and the first rotating seat 4. When the first adjustment member 51 removes its pushing force on the first rotating seat 4, the second elastic member 52 provides a preload force to the first rotating seat 4 to return it to its original position. In this way, the first adjustment member 51 and the second elastic member 52 can form a set of opposing forces applied to the first rotating seat 4, which can cause the first rotating seat 4 to reciprocate in the first direction, thereby adjusting the position of the projection point of the transmitting end 200 at the reflecting end 300 in the first direction.
[0050] See Figure 4 Furthermore, the preload force provided by the second elastic element 52 to the first rotating seat 4 is either a pushing force or a pulling force. When the preload force is a pushing force, the connecting seat 3 has a first blind hole 33 at a position corresponding to the second elastic element 52, and the first rotating seat 4 has a second blind hole 41 corresponding to the first blind hole 33. The two ends of the second elastic element 52 are respectively placed in the first blind hole 33 and the second blind hole 41. The first blind hole 33 and the second blind hole 41 allow for the installation and positioning of the second elastic element 52, making the installation of the second elastic element 52 extremely simple.
[0051] Specifically, when the preload provided by the second elastic element 52 to the first rotating seat 4 is a pushing force, the first adjusting element 51 and the second elastic element 52 can be respectively disposed on opposite sides of the rotation center of the first rotating seat 4. At this time, the first adjusting element 51 and the second elastic element 52 can be located on the same side of the first rotating seat 4 (see...). Figure 4Alternatively, the first adjusting member 51 and the second elastic member 52 are located on opposite sides of the first rotating seat 4. The first adjusting member 51 applies a thrust to the first rotating seat 4 away from the first adjusting member 51, and the second elastic member 52 provides a preload force (i.e., a pushing force) to the first rotating seat 4 away from the second elastic member 52. When the first rotating seat 4 is pushed to rotate by the first adjusting member 51, the rotation of the first rotating seat 4 causes the second elastic member 52 to be compressed. When the first adjusting member 51 removes the thrust applied to the first rotating seat 4, the restoring force of the second elastic member 52 pushes the first rotating seat 4 to rotate away from the connecting seat 3, thereby enabling the first rotating seat 4 to reciprocate in the first direction.
[0052] In addition, the first adjusting member 51 and the second elastic member 52 can be simultaneously disposed on the same side of the rotation center of the first rotating seat 4. Further, the first adjusting member 51 and the second elastic member 52 can be disposed on the same side of the first rotating seat 4. In this case, the first adjusting member 51 provides a pushing force to the first rotating seat 4 away from the connecting seat 3, and the second elastic member 52 provides a pulling force to the first rotating seat 4 close to the connecting seat 3. Alternatively, the first adjusting member 51 and the second elastic member 52 can also be disposed on opposite sides of the first rotating seat 4. The first adjusting member 51 provides a pushing force towards the second elastic member 52 on one side of the first rotating seat 4, and the second elastic member 52 provides a pushing force towards the first adjusting member 51 on the other side of the first rotating seat 4. This can also achieve the reciprocating rotation of the first rotation in the first direction.
[0053] It should be noted that when the preload provided by the second elastic element 52 to the first rotating seat 4 is a tension force, that is, when the first adjusting element 51 and the second elastic element 52 are simultaneously located on the same side of the rotation center of the first rotating seat 4 and both are located on the same side of the first rotation, the second elastic element 52 can be a compression spring. In this case, the connecting seat 3 and the first rotating seat 4 can be respectively provided with connecting parts (not shown in the figure) that are connected to both ends of the second elastic element 52.
[0054] In this embodiment, the distance from the first adjusting member 51 to the rotation center of the first rotating seat 4 is greater than the distance from the second elastic member 52 to the rotation center of the first rotating seat 4. This makes the lever arm of the first adjusting member 51 to the rotation center of the first rotating seat 4 greater than the lever arm of the second elastic member 52 to the rotation center of the first rotating seat 4. This ensures that even when the first adjusting member 51 applies a large force to the first rotating seat 4, the rotation angle of the first rotating seat 4 remains small, preventing excessive rotation of the first rotating seat 4 and thus avoiding increased deviation in the adjustment of the transmitter 200 in the first direction. This also makes it easier for personnel to operate the first adjusting member 51 and reduces the difficulty of adjusting the first rotating seat 4 in the first direction.
[0055] See Figure 2 , Figure 5 and Figure 6Specifically, the second adjustment assembly 7 includes a second adjustment member 71 and a third elastic member 72. The second adjustment member 71 passes through the first rotating seat 4 and abuts against the second rotating seat 6. The second adjustment member 71 can push the second rotating seat 6 to rotate around its rotation center in a second direction. The third elastic member 72 is disposed between the first rotating seat 4 and the second rotating seat 6. When the second adjustment member 71 removes its pushing force on the second rotating seat 6, the third elastic member 72 provides a preload force to the second rotating seat 6 to return it to its original position. In this way, the second adjustment member 71 and the third elastic member 72 can form a set of opposing forces applied to the second rotating seat 6, which allows the second rotating seat 6 to reciprocate in the second direction, thereby adjusting the projection point position of the transmitting end 200 at the reflecting end 300 in the second direction.
[0056] See Figure 5 Furthermore, the preload provided by the third elastic element 72 to the second rotating seat 6 is either a pushing force or a pulling force. When the preload is a pushing force, the first rotating seat 4 is also provided with a third blind hole 42 at the position corresponding to the third elastic element 72, and the second rotating seat 6 is provided with a fourth blind hole 61 corresponding to the third blind hole 42. The two ends of the third elastic element 72 are respectively placed in the third blind hole 42 and the fourth blind hole 61. By setting the third blind hole 42 and the fourth blind hole 61 in this way, the third elastic element 72 can be installed and limited, and the installation of the third elastic element 72 is extremely simple.
[0057] Specifically, when the preload provided by the third elastic element 52 to the second rotating seat 6 is a pushing force, the second adjusting element 71 and the third elastic element 72 can be respectively disposed on opposite sides of the rotation center of the second rotating seat 6. At this time, the second adjusting element 71 and the third elastic element 72 can be located on the same side of the second rotating seat 6 (see...). Figure 5 Alternatively, the second adjusting member 71 and the third elastic member 72 are located on opposite sides of the first rotating seat 4. The second adjusting member 71 applies a thrust to the second rotating seat 6 away from the second adjusting member 71, and the third elastic member 72 provides a preload force to the second rotating seat 6 away from the third elastic member 72. When the second rotating seat 6 is pushed to rotate by the second adjusting member 71, the rotation of the second rotating seat 6 causes the third elastic member 72 to be compressed. When the second adjusting member 71 removes the thrust applied to the second rotating seat 6, the restoring force of the third elastic member 72 pushes the second rotating seat 6 to rotate away from the connecting seat 3, thereby enabling the second rotating seat 6 to reciprocate in the second direction.
[0058] In addition, the second adjusting member 71 and the third elastic member 72 can be simultaneously disposed on the same side of the rotation center of the second rotating seat 6. Further, the second adjusting member 71 and the third elastic member 72 can be disposed on the same side of the second rotating seat 6. In this case, the second adjusting member 71 provides a thrust to the second rotating seat 6 away from the first rotating seat 4, and the third elastic member 72 provides a pull to the second rotating seat 6 close to the first rotating seat 4. Alternatively, the second adjusting member 71 and the third elastic member 72 can also be disposed on opposite sides of the second rotating seat 6. The second adjusting member 71 provides a thrust towards the third elastic member 72 on one side of the second rotating seat 6, and the third elastic member 72 provides a thrust towards the second adjusting member 71 on the other side of the second rotating seat 6. This can also achieve the reciprocating rotation of the second rotation in the second direction.
[0059] It should be noted that when the preload provided by the third elastic element 72 to the second rotating seat 6 is a tension force, that is, when the second adjusting element 71 and the third elastic element 72 are simultaneously located on the same side of the rotation center of the second rotating seat 6 and both are located on the same side of the second rotating seat 6, the third elastic element 72 can be a compression spring. In this case, the first rotating seat 4 and the second rotating seat 6 can be respectively provided with connecting parts (not shown in the figure) that are connected to both ends of the third elastic element 72.
[0060] In this embodiment, the distance from the second adjusting member 71 to the rotation center of the second rotating seat 6 is greater than the distance from the third elastic member 72 to the rotation center of the second rotating seat 6. This makes the lever arm of the second adjusting member 71 to the rotation center of the second rotating seat 6 greater than the lever arm of the third elastic member 72 to the rotation center of the second rotating seat 6. Consequently, when the second adjusting member 71 applies a large force to the second rotating seat 6, the rotation angle of the second rotating seat 6 is smaller, avoiding excessive rotation of the second rotating seat 6 which could increase the deviation of the transmitter 200 in the second direction. This allows for easier operation of the second adjusting member 71 and reduces the difficulty of adjusting the second rotating seat 6 in the second direction.
[0061] Specifically, both the first adjusting member 51 and the second adjusting member 71 can be screws or micrometer heads. By rotating the screw or micrometer head, a pushing force can be applied to or removed from the first rotating seat 4 and the second rotating seat 6. In this embodiment, both the first adjusting seat and the second adjusting seat use micrometer heads, which allows for more precise adjustment of the rotation angle of the first rotating seat 4 or the second rotating seat 6, further improving the adjustment accuracy of the transmitting end 200 in the first and second directions.
[0062] See Figure 5 , Figure 6Furthermore, the multi-dimensional adjustment device 100 also includes a first rotating shaft 8, which is fixed to the first rotating seat 4. A first bearing 9 is provided on the first rotating shaft 8. The connecting seat 3 includes a first seat body 3a and a second seat body 3b. The first seat body 3a or the second seat body 3b is provided with a first opening groove 3a1. The first bearing 9 is placed in the first opening groove 3a1. The second seat body 3b or the first seat body 3a is located on one side of the opening of the first opening groove 3a1 and abuts against the first bearing 9. The second seat body 3b is connected and fixed to the first seat body 3a. The connecting piece 23 is threadedly connected to the first seat body 3a or the second seat body 3b. A first clearance groove 31 is opened on the first seat body 3a or the second seat body 3b. A first bearing 9 is provided on the first rotating shaft 8, so that the first rotating seat 4 can be fixed as a whole with the inner ring of the first bearing 9. Rolling friction is formed between the inner and outer rings of the first bearing 9, which can reduce the rotational friction of the first rotating seat 4. The first seat body 3a has a first opening groove 3a1 to accommodate the first bearing 9, and the second seat body 3b abuts against the first bearing 9 and is fixed to the first seat body 3a. On the one hand, it can facilitate the installation of the first bearing 9 on the connecting seat 3. On the other hand, it can form a surface and line contact structure between the outer surface of the first bearing 9 and the connecting seat 3. This can effectively control the force on the outer ring of the first bearing 9. Compared with the full contact structure where the outer surface of the first bearing 9 is fitted with the connecting seat 3, this design structure can avoid the outer ring of the first bearing 9 being subjected to excessive force, which would squeeze the inner ring and increase the rotational friction of the first seat body 3a, thereby affecting the rotation of the first rotating seat 4 in the first direction.
[0063] In this embodiment, the first seat 3a and the second seat 3b form a U-shaped structure. The first rotating seat 4 is positioned above the space between the first seat 3a and the second seat 3b. The first adjusting member 51 and the first opening groove 3a1 are provided on the first seat 3a. The connecting member 23 is threadedly connected to the second seat 3b. The first clearance groove 31 is provided on the second seat 3b. A second clearance groove 32 is also provided at the bottom of the second seat 3b, which reduces the overall weight of the connecting seat 3. In one of the above embodiments, when the first adjusting member 51 and the second elastic member 52 are located on the same side of the connecting seat 3, the first blind hole 33 is provided on the first seat 3a.
[0064] In this embodiment, the first direction is horizontal. The first bearing 9 is located at the bottom of the first rotating seat 4. The bottom of the first rotating seat 4 is inserted into the connecting seat 3 via the first rotating shaft 8. The number of first bearings 9 can be set to 1, 2, etc., as needed. In this embodiment, 2 are set. The two first bearings 9 are spaced apart on the first rotating shaft 8 and are both located at the bottom of the first rotating seat 4, thereby increasing the structural stability of the first rotating shaft 8 and the first opening groove 3a1. Furthermore, the first seat body 3a of the connecting seat 3 is provided with a support member 30 at the bottom of the first opening groove 3a1. The support member 30 abuts against the first bearing 9 and can limit the axial movement of the first bearing 9 within the first opening groove 3a1. This makes the first rotating seat 4 more securely installed. The first rotating seat 4 adopts this single-sided installation structure, which simplifies the structure of the connecting seat 3, reduces costs, and makes the multi-dimensional adjustment device 100 smaller in size.
[0065] See Figure 6 Furthermore, the multi-dimensional adjustment device 100 also includes a second rotating shaft 10, which is fixed to the second rotating seat 6. A second bearing 20 is provided on the second rotating shaft 10. The first rotating seat 4 includes a third seat body 4a and a fourth seat body 4b. The third seat body 4a or the fourth seat body 4b is provided with a second opening groove 4a1. The second bearing 20 is placed in the second opening groove 4a1. The fourth seat body 4b or the third seat body 4a is located on one side of the opening of the second opening groove 4a1 and abuts against the second bearing 20. The fourth seat body 4b is connected and fixed to the third seat body 4a. The second rotating shaft 8 is connected and fixed to the first seat body 3a. Similarly, a second bearing 20 is provided on the second rotating shaft 10, so that the second rotating seat 6 can be fixed as a whole with the inner ring of the second bearing 20. Rolling friction is formed between the inner and outer rings of the second bearing 20, which can reduce the rotational friction of the second rotating seat 6. The third seat 4a has a second opening groove 4a1 to accommodate the second bearing 20, and the fourth seat 4b abuts against the second bearing 20 and is fixed to the third seat 4a. On the one hand, this facilitates the installation of the second bearing 20 on the first rotating seat 4, and on the other hand, it can form a surface and line contact structure between the outer surface of the second bearing 20 and the first rotating seat 4. This can effectively control the force on the outer ring of the second bearing 20. Compared with the full contact structure where the outer surface of the second bearing 20 is fitted with the first rotating seat 4, this design structure can avoid the outer ring of the second bearing 20 being subjected to excessive force, which would squeeze the inner ring and increase the rotational friction of the second rotating seat 6, thus affecting the rotation of the second rotating seat 6 in the second direction.
[0066] In this embodiment, the second rotating shaft 10 is horizontally arranged, the third base 4a has a 90-degree inverted U-shaped structure, the second rotating seat 6 is placed in the middle of the third base 4a, and the third base 4a has second opening slots 4a1 on both sides of the second rotating seat 6. The second rotating shaft 10 passes through the second rotating seat 6 and extends into the second opening slots 4a1, and the portion of the second rotating shaft 10 located in each second opening slot 4a1 is provided with at least one second bearing 20. The U-shaped structure of the third base 4a allows the second rotating seat 6 to be embedded in the first rotating seat 4, thereby further reducing space occupation and achieving a miniaturized structure of the device, while also reducing the weight of the parts.
[0067] In one of the above embodiments, the second adjusting member 71, the second blind hole 41, and the third blind hole 42 are all provided on the third seat 4a, and the fourth blind hole 61 is provided on the second rotating seat 6.
[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
