Description

Technical Field

[0001] The present invention belongs to the field of component position correction, and in particular relates to a multi-dimensional adjustment device. Background Art

[0002] A through-beam sensor is a device that detects objects by changing the optical path. It has a wide range of applications, one of which is the thickness detection of objects on a production line. This involves setting a through-beam sensor on the production line to detect the thickness of the object and determine whether the material meets production specifications.

[0003] When installing a through-beam sensor, the transmitter and reflector need to be set up on opposite sides of the production line respectively. When an object passes by, the transmitter needs to determine whether the current material is the target material by whether it receives the feedback signal from the reflector. During installation, in order to enable the signal emitted by the transmitter to be projected onto the target area of ​​the reflector, when the signal is visible light, the transmitter needs to be calibrated in three dimensions: left and right deflection, up and down deflection, and vertical movement. The landing point of the visible light projected onto the target area of ​​the reflector is used to determine whether it is installed in place.

[0004] The existing installation method for the reflector end is fixed, that is, after the initial calibration of the transmitter position, it is fixed to the production line with screws or bolts. After a certain period of use, the signal emitted by the transmitter will be offset due to the influence of environmental vibration or when it needs to adapt to the production of different material thicknesses, 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 personnel to move the position of the transmitter as a whole in the relevant dimensions during operation. 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 on the reflector end, thereby increasing the difficulty of transmitter position calibration and greatly reducing production efficiency. Summary of the Invention

[0005] The multi-dimensional adjustment device provided by the present invention is intended to solve the problem in the prior art that the adjustment of the target object is difficult and leads to low production efficiency.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention 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 only used to explain the present invention and are not intended to limit the present invention.

[0042] See also Figure 1An embodiment of the present invention provides a multi-dimensional adjustment device 100, which is used to adjust the transmitting end 200 of the through-beam sensor so that the visible light emitted by the transmitting end 200 can be accurately projected onto the target area of ​​the reflecting end 300. In addition, a material conveying platform 400 is provided between the transmitting end 200 and the reflecting end 300. The thickness of the material on the conveying platform 400 is adjustable. Therefore, during use, the transmitting end 200 also needs to be adaptively adjusted in height through the multi-dimensional adjustment device 100 according to the different thicknesses of the material to avoid the visible light emitted by the transmitting end 200 fixed at the same height being always blocked by the material, thereby losing the purpose of detecting the target parameters (including but not limited to the thickness of the material). In an 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 transmitter 200 and the reflector 300 are arranged on opposite sides of the conveying platform 400. The transmitter 200 emits visible light and projects it onto the reflector 300, which then reflects the signal back to the transmitter 200. Visible light includes but is not limited to red light, green light, blue light, and laser. During use, under the same material thickness, the light beam emitted by the transmitter 200 can be projected onto the target area of ​​the reflector 300, and the reflector 300 then feeds the signal back to the transmitter 200. When the transmitter 200 receives the feedback signal from the reflector 300, it indicates that the current material thickness on the conveying platform 400 meets production requirements. When the light beam emitted by the transmitter 200 is blocked and the transmitter 200 does not receive the feedback signal from the reflector 300, it indicates that the current material on the conveying platform 400 has been replaced with a material of a new thickness, reminding personnel to operate the supporting production parameters after the material is replaced, and at the same time adjust the vertical height of the transmitter 200 to adapt to the normal production of the equipment, achieving the purpose of thickness detection and reminder.

[0043] See also Figure 2-Figure 3 Specifically, the multi-dimensional adjustment device 100 includes a mounting member 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. Among them, the mounting member 1 is used to be fixed on one side of the conveying platform 400, the lifting assembly 2 is fixed on the mounting member 1, the connecting seat 3 is fixed on the lifting end of the lifting assembly 2 and is driven to move up and down by the lifting assembly 2, the first rotating seat 4 is rotatable around the first direction on the connecting seat 3, the first adjustment assembly 5 is arranged 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 rotatable around the second direction on the first rotating seat 4, and the second direction is arranged perpendicular to the first direction, the transmitting end 200 is fixed on the second rotating seat 6, and the second adjustment assembly 7 is arranged 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 transmitting end 200 of the through-beam sensor on the second rotating seat 6 and allowing the second adjusting component 7 to drive the second rotating seat 6 to rotate in the second direction, the transmitting end 200 can be adjusted in the second direction. The second rotating seat 6 can be rotatably installed on the first rotating seat 4 and allowing the first adjusting component 51 to drive the first rotating seat 4 to rotate in the first direction. The first rotating seat 4 can drive the second rotating seat 6 to rotate in the first direction, so that the transmitting end 200 can be adjusted in the first direction. The first rotating seat 4 can be rotatably installed on the connecting seat 3. The connecting seat 3 is fixed to the lifting end of the lifting component 2. The lifting component 2 can drive the first rotating seat 4 to rise and fall through the connecting seat 3, so that the transmitting end 200 can be adjusted in the vertical direction, and then the position of the transmitting end 200 can be adjusted in three directions. In this way, the visible light emitted by the transmitting end 200 can be accurately and conveniently projected onto the target area of ​​the reflecting end 300.

[0045] The multi-dimensional adjustment device 100 provided by the present invention adjusts the transmitting end 200 in a central rotation manner in both the first direction and the second direction. During adjustment, there is no need to change the coordinate position of the transmitting end 200 on the plane. The visible light emitted by the transmitting end 200 can be accurately and quickly projected onto the target area of ​​the reflecting end 300, reducing the difficulty of adjustment and improving the adjustment accuracy. At the same time, the transmitting end 200 can also be adjusted in the vertical height, which can be adapted to the target parameter detection required by different production environments. The synchronous adjustment of the transmitting end 200 in three dimensions has high adjustment accuracy, high adjustment efficiency, and a wide range of applications.

[0046] See also Figure 2 Specifically, the lifting assembly 2 includes a slide rail 21, a slider 22, a connector 23, and a first elastic member 24. The slide rail 21 is vertically arranged on the mounting member 1, the slider 22 cooperates with the slide rail 21, the connecting seat 3 is fixed to the slider 22, and the connector 23 is arranged above the connecting seat 3. One end of the connector 23 is threadedly connected to the connecting seat 3, and the other end passes through the mounting member 1 and abuts against the mounting member 1. Specifically, one end of the connector 23 passing through the mounting member 1 is provided with an external locking portion 231, and the locking portion 231 abuts against the surface of the mounting member 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 member 24 is sleeved on the connector 23 and provides a downward pre-tightening force to the connecting seat 3. In this way, through the connecting member 23, the connecting seat 3 can be driven to drive the slider 22 to move 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 provision of the first elastic member 24 can avoid the matching clearance between the connecting member 23 and the connecting seat 3 from bouncing up and down when subjected to external force, thereby ensuring that the slider 22 drives the transmitting end 200 to move in the vertical direction and stably remains in the current position, thereby improving the accuracy of the vertical adjustment of the transmitting end 200.

[0047] In this embodiment, the connecting member 23 may be provided with threads at a portion that is threadedly matched with the slider 22 , or a screw rod may be directly used.

[0048] See also Figure 2 Furthermore, the connecting base 3 is provided with a first avoidance groove 31, and the connecting member 23 passes through the connecting base 3 and extends into the first avoidance groove 31. The provision of the first avoidance groove 31 can avoid an excessively large contact area between the connecting member 23 and the connecting base 3, thereby reducing the resistance generated when the connecting member 23 rotates in the connecting base 3.

[0049] See also 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 is disposed through the connecting base 3 and abuts against the first rotating base 4. The first adjustment member 51 can push the first rotating base 4 to rotate about its rotation center in the first direction. The second elastic member 52 is disposed between the connecting base 3 and the first rotating base 4. The second elastic member 52 provides a preload force to the first rotating base 4 to return it to its original position when the first adjustment member 51 releases the force exerted on the first rotating base 4. In this way, the first adjustment member 51 and the second elastic member 52 form a set of opposing forces exerted on the first rotating base 4, causing the first rotating base 4 to rotate back and forth in the first direction, thereby adjusting the projection point position of the transmitting end 200 on the reflecting end 300 in the first direction.

[0050] See also Figure 4 Furthermore, the preload force provided by the second elastic member 52 to the first rotating seat 4 is a pushing force or a pulling force. When the preload force is a pushing force, the connecting seat 3 is provided with a first blind hole 33 at a position corresponding to the second elastic member 52, and the first rotating seat 4 is provided with a second blind hole 41 corresponding to the first blind hole 33. The two ends of the second elastic member 52 are respectively placed in the first blind hole 33 and the second blind hole 41. The provision of the first blind hole 33 and the second blind hole 41 allows for the installation and position limiting of the second elastic member 52, making the installation of the second elastic member 52 extremely simple.

[0051] Specifically, when the pre-tightening force provided by the second elastic member 52 to the first rotating seat 4 is a driving force, the first adjusting member 51 and the second elastic member 52 can be respectively arranged on opposite sides of the rotation center of the first rotating seat 4. In this case, the first adjusting member 51 and the second elastic member 52 can be located on the same side of the first rotating seat 4 (see Figure 4), or 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 pre-tightening 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 first rotating seat 4 rotates so that the second elastic member 52 is compressed. When the first adjusting member 51 cancels 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 rotate back and forth in the first direction.

[0052] In addition, the first adjusting member 51 and the second elastic member 52 can be simultaneously arranged 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 arranged on the same side of the first rotating seat 4. At this time, the first adjusting member 51 provides a thrust 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; or, the first adjusting member 51 and the second elastic member 52 can also be arranged on opposite sides of the first rotating seat 4, the first adjusting member 51 provides a thrust toward the second elastic member 52 on one side of the first rotating seat 4, and the second elastic member 52 provides a thrust toward the first adjusting member 51 on the other side of the first rotating seat 4, which can also realize the reciprocating rotation of the first rotation in the first direction.

[0053] It should be noted that when the pre-tightening force provided by the second elastic member 52 to the first rotating seat 4 is a pulling force, that is, one embodiment is when the first adjusting member 51 and the second elastic member 52 are simultaneously arranged on the same side of the rotation center of the first rotating seat 4 and both are simultaneously located on the same side of the first rotation, the second elastic member 52 can adopt a compression spring. At this time, the connecting seat 3 and the first rotating seat 4 can respectively be provided with connecting parts connected to the two ends of the second elastic member 52 (not shown in the figure).

[0054] In this embodiment, the distance between the first adjusting member 51 and the rotation center of the first rotating base 4 is greater than the distance between the second elastic member 52 and the rotation center of the first rotating base 4. This ensures that the force arm between the first adjusting member 51 and the rotation center of the first rotating base 4 is greater than the force arm between the second elastic member 52 and the rotation center of the first rotating base 4. As a result, even when the first adjusting member 51 applies a large force to the first rotating base 4, the rotation angle of the first rotating base 4 remains small, thereby preventing the first rotating base 4 from rotating excessively and causing an increase in the deviation of the transmitter 200 in the first direction. This allows personnel to more easily operate the first adjusting member 51, reducing the difficulty of adjusting the first rotating base 4 in the first direction.

[0055] See also 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 is provided on 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 the second direction. The third elastic member 72 is provided between the first rotating seat 4 and the second rotating seat 6. The third elastic member 72 provides a pre-tightening force to the second rotating seat 6 to return to its original position when the second adjustment member 71 cancels the pushing force on the second rotating seat 6. 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, so that the second rotating seat 6 can be rotated back and forth in the second direction, thereby adjusting the projection point position of the transmitting end 200 on the reflecting end 300 in the second direction.

[0056] See also Figure 5 Furthermore, the preload force provided by the third elastic member 72 to the second rotating seat 6 is a pushing force or a pulling force. When the preload force is a pushing force, the first rotating seat 4 is further provided with a third blind hole 42 at a position corresponding to the third elastic member 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 member 72 are respectively placed in the third blind hole 42 and the fourth blind hole 61. The arrangement of the third blind hole 42 and the fourth blind hole 61 in this manner allows the third elastic member 72 to be installed and limited in position, making the installation of the third elastic member 72 extremely simple.

[0057] Specifically, when the pre-tightening force provided by the third elastic member 52 to the second rotating seat 6 is a driving force, the second adjusting member 71 and the third elastic member 72 can be respectively arranged on opposite sides of the rotation center of the second rotating seat 6. In this case, the second adjusting member 71 and the third elastic member 72 can be located on the same side of the second rotating seat 6 (see Figure 5 ), or 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 pre-tightening 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 second rotating seat 6 rotates so that the third elastic member 72 is compressed. When the second adjusting member 71 cancels 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 rotate back and forth in the second direction.

[0058] In addition, the second adjusting member 71 and the third elastic member 72 can also be arranged 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 arranged on the same side of the second rotating seat 6. At this time, 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 pulling force to the second rotating seat 6 close to the first rotating seat 4; or, the second adjusting member 71 and the third elastic member 72 can also be arranged on opposite sides of the second rotating seat 6, the second adjusting member 71 provides a thrust toward the third elastic member 72 on one side of the second rotating seat 6, and the third elastic member 72 provides a thrust toward the second adjusting member 71 on the other side of the second rotating seat 6, which can also realize the reciprocating rotation of the second rotation in the second direction.

[0059] It should be noted that when the pre-tightening force provided by the third elastic member 72 to the second rotating seat 6 is a pulling force, that is, when the second adjusting member 71 and the third elastic member 72 are simultaneously arranged on the same side of the rotation center of the second rotating seat 6 and both are simultaneously located on the same side of the second rotating seat 6, the third elastic member 72 can adopt a compression spring. At this time, the first rotating seat 4 and the second rotating seat 6 can be respectively provided with connecting parts connected to the two ends of the third elastic member 72 (not shown in the figure).

[0060] In this embodiment, the distance between the second adjusting member 71 and the rotation center of the second rotating base 6 is greater than the distance between the third elastic member 72 and the rotation center of the second rotating base 6. This ensures that the force arm between the second adjusting member 71 and the rotation center of the second rotating base 6 is greater than the force arm between the third elastic member 72 and the rotation center of the second rotating base 6. As a result, when the second adjusting member 71 applies a large force to the second rotating base 6, the rotation angle of the second rotating base 6 is small, thereby preventing the second rotating base 6 from rotating excessively and causing an increase in the deviation of the transmitter 200 in the second direction. This allows personnel to more easily operate the second adjusting member 71, reducing the difficulty of adjusting the second rotating base 6 in the second direction.

[0061] Specifically, the first adjustment member 51 and the second adjustment member 71 can both be screws or micrometer heads, so that by rotating the screws or the screws of the micrometer heads, the driving force applied to the first rotating seat 4 and the second rotating seat 6 can be applied or canceled. In this embodiment, the first adjustment seat and the second adjustment seat both use micrometer heads, which can more precisely adjust 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 direction and the second direction.

[0062] See also 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, and 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, and the first bearing 9 is placed in the first opening groove 3a1. The second seat body 3b or the first seat body 3a is provided on one side of the slot 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, and the connecting member 23 is threadedly connected to the first seat body 3a or the second seat body 3b, and the first avoidance groove 31 is opened on the first seat body 3a or the second seat body 3b. A first bearing 9 is arranged on the first rotating shaft 8, so that the first rotating seat 4 can be fixed into a whole with the inner ring of the first bearing 9, and rolling friction is formed between the inner ring and the outer ring of the first bearing 9, which can reduce the rotational friction of the first rotating seat 4. The first seat body 3a is provided with a first open groove 3a1 to accommodate the first bearing 9, and the second seat body 3b is in contact with the first bearing 9 and 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, and on the other hand, it can form a surface and line contact structure between the outside of the first bearing 9 and the connecting seat 3, so that the bearing force of the outer ring of the first bearing 9 can be effectively controlled. Compared with the full contact structure of the outside of the first bearing 9 and the connecting seat 3, this design structure can avoid the outer ring of the first bearing 9 being subjected to excessive force and squeezing the inner ring, resulting in increased 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 base 3a and the second base 3b form a forward U-shaped structure, with the first rotating base 4 positioned above and between the first and second bases 3a, 3b. The first adjusting member 51 and the first opening slot 3a1 are disposed on the first base 3a, the connecting member 23 is threadedly connected to the second base 3b, the first air-avoidance slot 31 is disposed on the second base 3b, and a second air-avoidance slot 32 is also defined at the bottom of the second base 3b. This reduces the overall weight of the connecting base 3. In one of the aforementioned embodiments, when the first adjusting member 51 and the second elastic member 52 are disposed on the same side of the connecting base 3, the first blind hole 33 is defined in the first base 3a.

[0064] In this embodiment, the first direction is the horizontal direction. The first bearing 9 is provided at the bottom of the first rotating seat 4. The bottom of the first rotating seat 4 is inserted into the connecting seat 3 through the first rotating shaft 8. The number of first bearings 9 can be set to 1, 2, etc. as needed. In this embodiment, 2 first bearings 9 are provided. 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. This increases 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 supporting member 30 at the bottom of the first opening groove 3a1. The supporting member 30 abuts against the first bearing 9. The supporting member 30 can limit the axial position of the first bearing 9 in the first opening groove 3a1. This can make the first rotating seat 4 more firmly installed. The first rotating seat 4 adopts this single-sided installation structure, which can simplify the structure of the connecting seat 3, reduce costs, and make the multi-dimensional adjustment device 100 miniaturized.

[0065] See also 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 provided on one side of the slot 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, and 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 into a whole with the inner ring of the second bearing 20, and rolling friction is formed between the inner ring and the outer ring of the second bearing 20, which can reduce the rotational friction of the second rotating seat 6. The third seat body 4a provides a second open groove 4a1 to accommodate the second bearing 20, and the fourth seat body 4b is in contact with the second bearing 20 and fixed to the third seat body 4a. On the one hand, it can facilitate 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 outside of the second bearing 20 and the first rotating seat 4, so that the bearing force of the outer ring of the second bearing 20 can be effectively controlled. Compared with the full contact structure of the outside of the second bearing 20 and the first rotating seat 4, this design structure can avoid the outer ring of the second bearing 20 being subjected to excessive force and squeezing the inner ring, resulting in increased rotational friction of the second rotating seat 6, thereby affecting the rotation of the second rotating seat 6 in the second direction.

[0066] In this embodiment, the second rotating shaft 10 is arranged horizontally, and the third base 4a has a 90-degree inverted U-shaped structure. The second rotating base 6 is positioned in the middle of the third base 4a. The third base 4a has second openings 4a1 on opposite sides of the second rotating base 6. The second rotating shaft 10 extends through the second rotating base 6 and into the second openings 4a1. The portion of the second rotating shaft 10 located within each second opening 4a1 is provided with at least one second bearing 20. The U-shaped structure of the third base 4a allows the second rotating base 6 to be embedded and installed within the first rotating base 4, thereby further effectively reducing space usage and achieving structural miniaturization of the device while also reducing component weight.

[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 base body 4 a , and the fourth blind hole 61 is provided on the second rotating base 6 .

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
