[0002] Currently, multi-point laser sensors are mounted on brackets and used to detect the horizontal relationship between the same platform or between two or more independent planes.

[0046] Example 1

[0047] Existing technologies for multi-point laser sensors include surface scanning and line scanning modes. Surface scanning mode keeps the lower surface of the sensor horizontal, enabling the detection of the height difference between two points within a specified area below the sensor. Line scanning mode keeps the lower surface of the sensor tilted, enabling the detection of the height difference between two points within a specified line segment below the sensor. Existing brackets only allow for installation and fixation in one orientation for multi-point laser sensors, and cannot adjust the orientation of the sensors, resulting in poor versatility.

[0048] To solve the above problems, such as Figures 1-3 As shown, this embodiment provides a height difference detection device, which includes a suspension assembly 1, an angle switching assembly 2, a support rod 3, and a base assembly 4. Specifically, the suspension assembly 1 includes a suspension bracket 11 and a height detector 12. The height detector 12 can be connected to the suspension bracket 11 in a horizontal or inclined state via the angle switching assembly 2. The top end of the support rod 3 is connected to the suspension bracket 11, and the suspension bracket 11 is configured to be adjustable relative to the support rod 3 along a first direction and a second direction. The bottom end of the support rod 3 is connected to the base assembly 4, and the support rod 3 is configured to be adjustable relative to the base assembly 4 along a third direction, with the second direction perpendicular to the first and third directions. In this embodiment, the first direction is X, the second direction is Y, the third direction is Z, and the height detector 12 is a multi-point laser sensor.

[0049] In this device, the suspension bracket 11 of the suspension assembly 1 is connected to the base assembly 4 via a support rod 3, so that the height detector 12 is positioned above the workpiece 10 to be inspected, enabling the height detector 12 to inspect the workpiece 10. When the height detector 12 is installed horizontally on the suspension bracket 11 via the angle switching component 2, it can perform surface scanning detection. When the height detector 12 is installed at an angle on the suspension bracket 11 via the angle switching component 2, it can perform line scanning detection. This height difference detection device uses an angle switching component 2 to achieve two installation postures for the height detector 12, meeting the application requirements of various postures of the height detector 12 and improving its versatility. Furthermore, the suspension bracket 11 is configured to be adjustable relative to the support rod 3 in the first and second directions, and the support rod 3 is configured to be adjustable relative to the base assembly 4 in the third direction, thereby enabling the height detector 12 to be adjusted in the first, second, and third directions, which meets the needs of most split platforms for point detection in confined spaces and improves versatility.

[0050] Specifically, the angle switching component 2 includes a first fastening screw 21 and a second fastening screw 22. The suspension bracket 11 is provided with an arc-shaped groove 111. The height detector 12 is provided with a first threaded hole and a second threaded hole on one side. The first fastening screw 21 passes through the arc-shaped groove 111 and is threadedly connected to the first threaded hole. The second threaded hole is detachably connected to the suspension bracket 11 through the second fastening screw 22. When the first fastening screw 21 is located at the first end of the arc-shaped groove 111, the height detector 12 is in a horizontal state. When the first fastening screw 21 is located at the second end of the arc-shaped groove 111, the height detector 12 is in a tilted state at a preset angle. When the height detector 12 needs to be in surface scanning mode, the first fastening screw 21 is loosened, and the first fastening screw 21 slides to the first end of the arc-shaped groove 111. Then, the height detector 12 is installed on the suspension bracket 11 via the first fastening screw 21 and the second fastening screw 22, so that the height detector 12 is installed on the suspension bracket 11 in a horizontal state. When the height detector 12 needs to be in line scanning mode, the first fastening screw 21 is loosened, and the first fastening screw 21 slides to the second end of the arc-shaped groove 111. Then, the height detector 12 is installed on the suspension bracket 11 via the first fastening screw 21 and the second fastening screw 22, so that the height detector 12 is installed on the suspension bracket 11 in a preset angle. During the adjustment of the height detector 12, the height detector 12 is slidably connected to the arc-shaped groove 111 via the first fastening screw 21, eliminating the need to detach the height detector 12 from the suspension bracket 11, thus improving the ease of operation.

[0051] In this embodiment, the suspension bracket 11 is provided with a first fixing hole 112 and a second fixing hole 113. When the first fastening screw 21 is located at the first end of the arc-shaped groove 111, the second threaded hole can be coaxial with the first fixing hole 112; when the first fastening screw 21 is located at the second end of the arc-shaped groove 111, the second threaded hole can be coaxial with the second fixing hole 113; the second fastening screw 22 can be selectively inserted into the first fixing hole 112 or the second fixing hole 113 and threadedly connected to the second threaded hole. When it is necessary to adjust the height detector 12 to a horizontal position, the first fastening screw 21 is loosened and the second fastening screw 22 is removed. The first fastening screw 21 slides along the arc-shaped groove 111 to the first end, and the second fastening screw 22 is inserted into the first fixing hole 112 and threadedly connected to the second threaded hole, so that the height detector 12 is in a horizontal position. When it is necessary to adjust the height detector 12 to an inclined posture, loosen the first fastening screw 21 and remove the second fastening screw 22. The first fastening screw 21 slides along the arc groove 111 to the second end, and the second fastening screw 22 passes through the second fixing hole 113 and is threaded to the second threaded hole, so that the height detector 12 is in an inclined posture at a preset angle, thereby realizing the posture adjustment of the height detector 12.

[0052] Because there is a gap between the second fastening screw 22 and the first fixing hole 112 or the second fixing hole 113, the assembly accuracy is affected. To solve the above problem, the angle switching assembly 2 also includes a clamping pin 23. The suspension bracket 11 is provided with a first pressing hole. When the height detector 12 is in a horizontal state, the clamping pin 23 is connected to the first pressing hole and the clamping pin 23 abuts against the side wall of the height detector 12; and / or the suspension bracket 11 is provided with a second pressing hole. When the height detector 12 is in an inclined state, the clamping pin 23 is connected to the second pressing hole and the clamping pin 23 abuts against the side wall of the height detector 12. In this embodiment, as Figure 4 As shown, when the height detector 12 is in a horizontal state, the clamping pin 23 is connected to the first crimping hole, and the clamping pin 23 abuts against the side wall of the height detector 12 to eliminate the gap error between the second fastening screw 22 and the first fixing hole 112; as Figure 1 As shown, when the height detector 12 is in a horizontal state, the clamping pin 23 is connected to the second pressing hole and the clamping pin 23 abuts against the side wall of the height detector 12 to eliminate the gap error between the second fastening screw 22 and the second fixing hole 113, thereby improving the installation accuracy of the height detector 12 and thus improving the detection accuracy of the height detector 12.

[0053] Preferably, such as Figure 1As shown, the suspension assembly 1 also includes a connecting component 13. The first end of the connecting component 13 is connected to the top of the support rod 3, and the second end of the connecting component 13 is fitted with a sliding screw 14. A height detector 12 is mounted on one end of the suspension bracket 11. The suspension bracket 11 is provided with a groove 115 extending along a first direction. The rod portion of the sliding screw 14 is slidably connected to the groove 115, and the suspension bracket 11 is connected to the connecting component 13 via the sliding screw 14. The suspension bracket 11 slides relative to the sliding screw 14 along the first direction via the groove 115 to adjust the position of the height detector 12 along the first direction. In this embodiment, the suspension bracket 11 is provided with two spaced-apart grooves 115, and two sliding screws 14 are slidably installed in each groove 115, improving the sliding stability of the suspension bracket 11.

[0054] Further, the connecting component 13 includes a hinge block 131 and an adjusting member 132. The first end of the hinge block 131 has a connecting hole extending vertically, and the hinge block 131 also has an opening communicating with the connecting hole. The adjusting member 132 is used to adjust the size of the opening. The support rod 3 can pass through and be interference-fitted into the connecting hole. A sliding screw 14 is installed at the second end of the hinge block 131. In this embodiment, the adjusting member 132 is an adjusting screw. One sidewall opposite the opening has a fourth fixing hole, and the other has a fourth threaded hole. The adjusting screw passes through the fourth fixing hole and is threaded into the fourth screw hole. By adjusting the screwing depth of the adjusting screw and the fourth threaded hole, the size of the opening is adjusted. In use, reducing the screwing depth allows the hinge block 131 to rotate 360° relative to the support rod 3, further adjusting the horizontal position of the height detector 12. Moreover, the hinge block 131 can move relative to the support rod 3 in a second direction, thus adjusting the height of the height detector 12. When the suspension bracket 11 rotates to the preset position relative to the support rod 3, the tightening depth of the adjusting screw is increased so that the support rod 3 is interference-fitted with the connecting hole to achieve fixation.

[0055] Furthermore, such as Figure 1 and Figure 5 As shown, the base assembly 4 includes a drive component 41, a base plate 42, and a support 43. The bottom end of the support rod 3 is connected to the support 43, and the support 43 is slidably connected to the base plate 42 in a third direction. The drive component 41 is connected to the base plate 42 and drives the support 43. The drive component 41 drives the support 43 to slide relative to the base plate 42. The drive component 41 drives the support 43 to move relative to the base plate 42 in a third direction, thereby adjusting the position of the support rod 3 and the suspension assembly 1 in the third direction and improving operability. Furthermore, the movement of the support 43 relative to the base plate 42 in the third direction allows the base plate 42 to fully extend into the external space of the narrow platform for placement, solving the problem of installation being impossible in a narrow space.

[0056] In this embodiment, the driving component 41 includes an adjusting handle 411 and a lead screw 412. The base plate 42 is provided with a supporting boss 421, which has a connecting groove 422. The adjusting handle 411 is rotatably connected to the connecting groove 422. The adjusting handle 411 is provided with two stop walls, which stop the supporting boss 421 from moving along the third direction on both sides. Therefore, the adjusting handle 411 will not move relative to the supporting boss 421. The adjusting handle 411 is connected to the lead screw 412. The end of the support 43 is provided with a third threaded hole, and the lead screw 412 is threadedly connected to the third threaded hole. When the adjusting handle 411 is rotated, the lead screw 412 drives the support 43 to move along the third direction, realizing multi-point selection and detection on a straight line within the detection range of the height detector 12, thus solving the problem of the single selection point in the existing fixed installation.

[0057] Furthermore, the base assembly 4 also includes a slide rail 44, a slider 45, and a limiting member 46. The slide rail 44 is disposed on the base plate 42, and the slider 45 is disposed on the bottom of the support 43. The slider 45 is slidably connected to the slide rail 44, which improves the sliding stability of the support 43 relative to the base plate 42 and improves the sliding accuracy of the suspension assembly 1. The limiting member 46 is connected to the base plate 42 and is used to stop the slider 45 to limit the maximum displacement of the slider 45 and prevent the slider 45 from falling off the slide rail 44. In this embodiment, there are two limiting members 46, which are used to stop the slider 45 at its extreme positions along a third direction.

[0058] It should be noted that this embodiment also provides the working principle of the height difference detection device, as follows:

[0059] When using this height difference detection device, the height detector 12 is fixed to the suspension bracket 11. By adjusting the position of the suspension bracket 11 along the first direction, the height detector 12 is positioned directly above the workpiece 10 to be tested. Two points within the scanning range of the height detector 12 are selected, and the positions of the two points are adjusted by the third direction, placing them on two independent planes respectively. The height detector 12 images the image, automatically detecting the height difference between the two points. When the workpiece 10 to be tested has multiple detection points, the angle of the height detector 12 and the detection points can be adjusted by rotating the suspension bracket 11. By setting and adjusting the spacing of the detection points, and by adjusting the position of the suspension bracket 11 along the first and third directions, the detection points are placed on the two planes to be tested for detection.

[0060] The height difference detection device has a simple structure and can achieve three-axis omnidirectional adjustment. The height detector 12 can rotate 360°. Together with the support rod 3, it can meet the needs of most split platforms for point detection in narrow spaces.

[0061] Example 2

[0062] like Figure 1 and Figure 6 As shown, this embodiment provides a height difference detection device, and the structure of the height difference detection device provided in this embodiment is basically the same as that in Embodiment 1, with only some differences in the suspension component 1. This embodiment will not describe the structure that is the same as that in Embodiment 1 again.

[0063] In this embodiment, the suspension bracket 11 is provided with a third fixing hole 114, which is located at the center of the arc-shaped groove 111. The second fastening screw 22 passes through the third fixing hole 114 and is threaded into the second threaded hole. When it is necessary to adjust the posture of the height detector 12, the first fastening screw 21 and the second fastening screw 22 are loosened. The first fastening screw 21 slides along the arc-shaped groove 111, and the height detector 12 rotates around the axis of the third fixing hole 114. When the height detector 12 is adjusted to the preset posture, the first fastening screw 21 and the second fastening screw 22 are tightened, thus realizing the posture adjustment of the height detector 12, meeting the application scenario requirements of various postures of the height detector 12, and improving its versatility.
