Description

Technical Field

[0001] This utility model relates to the field of visual inspection, and more specifically, to a three-dimensional scanning mechanism. Background Technology

[0002] In the field of visual inspection, 3D scanning of products is necessary to improve inspection accuracy and comprehensiveness. Traditional 3D scanning mechanisms are equipped with only simple rotary tables. Although they can achieve automatic rotation of the product, the scanning unit lacks sufficient degrees of freedom, making it difficult to adapt to the optimal scanning distance for different products. This can easily lead to blind spots, resulting in missing 3D scan data and limited inspection accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a three-dimensional scanning mechanism that can flexibly adjust the scanning distance, thereby improving the integrity and accuracy of three-dimensional data acquisition.

[0004] A three-dimensional scanning mechanism, comprising:

[0005] A rotary clamping assembly includes a rotary drive and a clamping unit, the rotary drive being used to drive the clamping unit to rotate about a first direction as an axis; and

[0006] The scanning assembly includes a horizontal drive assembly, a vertical drive assembly, and a scanning unit. The scanning unit is mounted above the clamping unit. The horizontal drive assembly drives the scanning unit to move along a second direction, and the vertical drive assembly drives the scanning unit to move along a third direction.

[0007] In the above technical solution, the rotary clamping component can clamp the target product and drive it to rotate around the first direction as an axis. The horizontal drive component and the vertical drive component drive the scanning unit to move in the second and third directions, respectively, thereby flexibly adjusting the distance between the scanning unit and the target product. This allows the scanning unit to match products of different shapes and sizes, improving the applicability of the scanning mechanism. At the same time, it enables omnidirectional scanning of the object surface without blind spots, improving the integrity and accuracy of three-dimensional data acquisition.

[0008] Furthermore, the clamping unit includes a clamping drive and two opposing jaws. The clamping drive is connected to the output end of the rotation drive, and the two jaws are connected to the clamping drive. The clamping drive is used to drive the two jaws to move closer or further apart.

[0009] In the above technical solution, a dual-jaw symmetrical clamping design is adopted, which realizes adaptive opening and closing action under the control of the clamping drive component. This can not only stably clamp products of different sizes, but also avoid product displacement during rotation, thus ensuring the stability of the object's posture during scanning.

[0010] Furthermore, one end of the clamping drive is provided with a mounting block, the mounting block is provided with a sliding groove, and the two grippers are slidably disposed in the sliding groove.

[0011] In the above technical solution, the sliding cooperation between the slide and the gripper keeps the movement trajectory of the gripper stable and accurate, effectively preventing the deflection of the object during clamping.

[0012] Furthermore, it also includes a lifting drive component, which is connected to the rotation drive component and is used to drive the clamping unit to move in a third direction.

[0013] In the above technical solution, the lifting drive component enables the vertical adjustment of the clamping assembly, providing space for the rotating clamping assembly to clamp the product and rotate it 180°.

[0014] Furthermore, the horizontal drive assembly includes a horizontal drive member and a first slide, the output end of the horizontal drive member is connected to the first slide, and the vertical drive assembly is mounted on the first slide.

[0015] In the above technical solution, the horizontal drive component is connected to the first slide block by a horizontal drive component. Its structure is simple and easy to implement. At the same time, it provides a stable bearing platform for the vertical drive component, ensuring the stability of the trajectory of the scanning unit when it moves laterally.

[0016] Furthermore, the vertical drive assembly includes a vertical drive member and a second slide, the output end of the vertical drive member is connected to the second slide, and the scanning unit is mounted on the second slide.

[0017] In the above technical solution, the vertical drive unit realizes the vertical movement of the scanning unit through an independent second slide, so that the vertical movement and the horizontal movement are independent of each other, thus ensuring the stability of the scanning unit's movement.

[0018] Furthermore, it also includes a gantry, on which the scanning component is mounted.

[0019] In the above technical solution, the gantry provides support for the scanning components, ensuring that the scanning unit has sufficient space to move. The clamping and rotating components pass under the gantry, providing space for the product to rotate, while ensuring that the product and the scanning unit are accurately aligned, effectively improving the rationality of the spatial layout.

[0020] Furthermore, the scanning unit is a three-dimensional line laser profile measuring instrument.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the rotating clamping component can clamp the target product and drive it to rotate around the first direction as an axis; the horizontal driving component and the vertical driving component drive the scanning unit to move in the second and third directions respectively, thereby flexibly adjusting the distance between the scanning unit and the target product, enabling the scanning unit to match products of different shapes and sizes, improving the applicability of the scanning mechanism, and realizing all-round scanning of the object surface without blind spots, thus improving the integrity and accuracy of three-dimensional data acquisition.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] Please refer to Figures 1 to 4 In a preferred embodiment, the three-dimensional scanning mechanism of this utility model mainly includes a rotary clamping assembly 1 and a scanning assembly 2. The rotary clamping assembly 1 includes a rotary drive 11 and a clamping unit 12. The rotary drive 11 drives the clamping unit 12 to rotate about a first direction X. The scanning assembly 2 includes a horizontal drive assembly 21, a vertical drive assembly 22, and a scanning unit 23. The scanning unit 23 is mounted above the clamping unit 12. The horizontal drive assembly 21 drives the scanning unit 23 to move along a second direction Y, and the vertical drive assembly 22 drives the scanning unit 23 to move along a third direction Z.

[0031] For example, the rotary drive component 11 can be an existing rotary drive device, such as a rotary cylinder, whose output end is connected to the clamping unit 12. The rotation axis of the rotary drive component 11 is parallel to the first direction X. The clamping unit 12 is used to clamp the product to be scanned. The rotary drive component 11 can drive the clamping assembly to rotate along the first direction X, thereby causing the product to rotate and making different surfaces of the product face the scanning unit 23. In this embodiment, the scanning unit 23 adopts a three-dimensional line laser profile measuring instrument. The horizontal drive component 21 and the vertical drive component 22 respectively drive the scanning unit 23 to move in the second direction Y and the third direction Z, thereby flexibly adjusting the distance between the scanning unit 23 and the target product, so that the scanning unit 23 can match products of different shapes and sizes, improving the applicability of the scanning mechanism, and realizing omnidirectional scanning of the object surface without blind spots, improving the integrity and accuracy of three-dimensional data acquisition.

[0032] Please refer to Figure 4 The clamping unit 12 includes a clamping drive 121 and two opposing grippers 122. The clamping drive 121 is connected to the output end of the rotary drive 11, and the two grippers 122 are connected to the clamping drive 121. The clamping drive 121 is used to drive the two grippers 122 to move closer or further apart. For example, the clamping drive 121 can be a clamping electric cylinder to improve accuracy and provide force control to prevent product damage. One end of the clamping drive 121 is connected to the rotary drive 11, and the other end is connected to the two grippers 122. The symmetrical clamping design with two grippers 122 enables adaptive opening and closing under the control of the clamping drive 121. This not only stably clamps products of different sizes but also prevents product displacement during rotation, ensuring the stability of the object's posture during scanning.

[0033] In this embodiment, one end of the clamping drive member 121 is provided with a mounting block 123, and the mounting block 123 is provided with a sliding groove 124. Two grippers 122 are slidably disposed in the sliding groove 124. For example, the sliding groove 124 is a T-shaped groove, and the grippers 122 are slidably connected to the sliding groove 124 through a T-shaped slider. In this embodiment, there are two sliding grooves 124, which are parallel to each other. The two grippers 122 are slidably connected to the two sliding grooves 124 respectively. The sliding cooperation between the sliding grooves 124 and the grippers 122 keeps the movement trajectory of the grippers 122 stable and accurate, effectively preventing deflection when clamping objects.

[0034] The rotary clamping assembly 1 of this embodiment also includes a lifting drive 13, which is connected to the rotary drive 11 and is used to drive the clamping unit 12 to move along the third direction Z. For example, the lifting drive 13 can be an existing linear drive device, such as a cylinder. The lifting drive 13 realizes automatic adjustment of the clamping unit 12 in the vertical direction, providing space for the rotary clamping assembly 1 to clamp the product and rotate it 180°.

[0035] Please refer to Figure 3 The horizontal drive assembly 21 includes a horizontal drive element 211 and a first slide block 212. The output end of the horizontal drive element 211 is connected to the first slide block 212, and the vertical drive assembly 22 is mounted on the first slide block 212. The horizontal drive element 211 can be an existing linear drive device, such as a linear module. The horizontal drive assembly 21, which connects to the first slide block 212, has a simple structure and is easy to implement. At the same time, it provides a stable support platform for the vertical drive assembly 22, ensuring the stability of the trajectory of the scanning unit 23 during lateral movement.

[0036] The vertical drive assembly 22 includes a vertical drive component 221 and a second slide block 222. The output end of the vertical drive component 221 is connected to the second slide block 222, and the scanning unit 23 is mounted on the second slide block 222. The vertical drive component 221 can be an existing linear drive device, such as a linear module. The vertical drive component 221 realizes the vertical movement of the scanning unit 23 through the independent second slide block 222, making the vertical movement independent of the horizontal movement and ensuring the stability of the movement of the scanning unit 23.

[0037] The three-dimensional scanning mechanism of this utility model also includes a gantry 3, on which the scanning component 2 is mounted. The gantry 3 provides support for the scanning component 2, ensuring that the scanning unit 23 has sufficient space to move. The rotating clamping component 1 passes under the gantry 3, providing space for the product to rotate, while ensuring that the product and the scanning unit 23 are accurately aligned, effectively improving the rationality of the spatial layout.
