Description

Technical Field

[0001] This utility model relates to a device for omnidirectional scanning of a six-sided workpiece. Background Technology

[0002] In various industrial fields such as precision manufacturing, electronic assembly, aerospace, and mold processing, as the demand for workpiece geometric accuracy and structural integrity testing continues to increase, 3D scanning equipment, as an important tool for acquiring object shape and surface feature data, has been widely used in quality control, reverse engineering, and digital modeling.

[0003] However, existing workpiece scanning technologies suffer from the following technical shortcomings and limitations:

[0004] Incomplete scan coverage, resulting in missing data.

[0005] Traditional scanning equipment typically consists of a combination of a fixed platform and a fixed-angle scanning head, which can only cover one or a few faces of a workpiece. For hexahedral workpieces with six orthogonal faces, manual flipping or multiple positioning scans are often required to acquire data for all faces. This method is not only inefficient, but also leads to the accumulation of data alignment errors due to multiple manual interventions, ultimately affecting the accuracy and reliability of the scanning results.

[0006] Lack of integrated handling and scanning coordination mechanism

[0007] In existing equipment, workpiece handling and positioning are often physically separated from the scanning system, making it impossible to build a closed-loop control system. Especially in automated production line scenarios, workpieces often require independent fixtures or dedicated platforms to assist in loading before entering the scanning station, resulting in discontinuous processes, repetitive positioning, and difficulties in system integration, making it difficult to meet the requirements of efficient collaboration in intelligent manufacturing.

[0008] The scanning structure is inflexible and has poor adaptability.

[0009] Many traditional scanning systems have rigid structures that cannot adapt to workpieces of various sizes or with significant structural differences. Especially in the fields of electronics and precision devices, many irregularly shaped workpieces have thin handles for support or are not in the center of gravity. Traditional platform structures are difficult to stably support or accurately align with the scanning area, resulting in frequent problems such as scanning dead angles and data distortion.

[0010] In summary, the technical background section of this utility model aims to describe the current state of the existing technical field. The deficiencies of the prior art indicate that the content of this section will provide necessary background information for understanding the technical contributions and innovations of this utility model. The signals disclosed in this background section are only intended to enhance the understanding of the overall background of this utility model and should not be regarded as implying any subjective intent in any form. Utility Model Content

[0011] In view of the above, the purpose of this utility model is to provide a device for omnidirectional scanning of a six-sided workpiece.

[0012] The technical solution adopted to achieve the purpose of this utility model is a device for omnidirectional scanning of a six-sided workpiece, comprising a support base, a conveying mechanism, a four-dimensional scanning component, and a two-dimensional scanning component.

[0013] The supporting base is used to support the entire device structure. The base is equipped with guide rails for the transport mechanism to move along them. The transport mechanism includes a front and rear moving module, a lifting guide rail, a lifting slide, and a load-bearing arm assembly. The front and rear moving module is installed on the supporting base and guides the lifting guide rail to slide back and forth in the horizontal direction. The lifting guide rail is a vertically set guide rail used to guide the lifting slide to move up and down. The lifting slide is equipped with a load-bearing arm assembly, which is symmetrically arranged on the left and right. It can pass through the support handles of the hexahedral workpiece from both sides, lift the workpiece and move it up and down and back and forth with the slide, thereby realizing the picking, placing and transporting of the hexahedral workpiece.

[0014] The four-dimensional scanning component is suspended on the central platform between the lifting guide rails and includes a rotating device and multiple scanning heads for scanning the bottom and side surfaces. The rotating device is used to drive the scanning heads to rotate and complete the scanning of the bottom surface and four side surfaces of the workpiece.

[0015] The two-dimensional scanning component is mounted on a support frame on the upper part of the device. It includes a support beam and an XY platform installed upside down below the beam. The XY platform includes two horizontally arranged moving modules to enable the top scanning head to move in the left-right and front-back directions, thereby completing the scanning of the top surface of the hexahedral workpiece.

[0016] Furthermore, the supporting base is provided with two parallel guide rails, and the front and rear moving module is provided with a sliding base. The base is slidably connected to the guide rails through a slider assembly, so that the conveying mechanism can slide back and forth along the base.

[0017] Furthermore, the lifting guide rail consists of two vertically arranged linear guide rails, which are respectively set on the two side columns of the front and rear moving modules. The lifting slide slides in cooperation with the guide rails through a slider, thereby achieving vertical lifting and lowering movements while maintaining a stable posture.

[0018] Furthermore, the load-bearing arm assembly includes two forks, which are mounted on the lifting slide and are used to pass under the support handle of the hexahedral workpiece to stably lift the workpiece at the scanning position.

[0019] Furthermore, the rotating device of the four-dimensional scanning component is located below the hexahedral workpiece and is driven by an electric rotating mechanism to rotate the scanning head around the hexahedral workpiece in order to collect side information.

[0020] Furthermore, the rotating device includes a rotating base, a rotating bracket, a driving mechanism, and a scanning head mounting bracket. The rotating base is a disc-shaped structure, fixedly installed on the central platform of the support base. The rotating bracket is rotatably connected to the rotating base and supported on the base by a bearing assembly. The driving mechanism is preferably a precision electric servo motor rotating platform, with the motor connected to the central shaft of the rotating bracket to drive the rotating bracket to rotate. The scanning head mounting bracket is located on the circumferential edge of the rotating bracket and is a ring or semi-ring bracket structure, with multiple scanning heads fixed at equal intervals along the outer ring of the rotating bracket.

[0021] Furthermore, the XY platform of the two-dimensional scanning component has a cross structure, with both the X-axis and Y-axis being linear slide rail modules, which are installed on a square cross slide under the supporting beam.

[0022] The beneficial effects of this utility model are:

[0023] Achieve 360-degree scanning with complete and uninterrupted data: Through the organic combination of four-dimensional scanning components and two-dimensional scanning components, it is possible to perform 360-degree scanning of the top, bottom and four sides of the workpiece, effectively ensuring the integrity and consistency of the scanned data and avoiding the problem of missing corner data caused by traditional single-sided scanning.

[0024] Workpiece handling and scanning are separated to improve stability and accuracy: By separating the handling mechanism from the scanning mechanism, the handling mechanism focuses on precise workpiece positioning and stable lifting, while the scanning mechanism focuses on data acquisition. The two do not interfere with each other, thus improving the overall scanning accuracy and operational reliability.

[0025] The rotating scanning mechanism improves scanning efficiency and surface coverage: The rotating device in the four-dimensional scanning component, together with the multi-scanning head surround structure, can realize continuous, multi-angle coverage scanning of the side of the workpiece, effectively avoiding the errors and time losses caused by multiple positioning and movement.

[0029] The present invention will now be described in this embodiment with reference to the accompanying drawings and some embodiments.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0031] The following description, in conjunction with the accompanying drawings and embodiments, further illustrates the device for omnidirectional scanning of a hexahedral workpiece according to the present invention, aiming to help understand the technical concept and specific implementation of the present invention. However, this description should not be construed as a limitation on the scope of protection of the present invention.

[0032] See Figure 1 As shown, a device for omnidirectional scanning of a six-sided workpiece includes a support base 101, a transport mechanism, a four-dimensional scanning component 106, and a two-dimensional scanning component. This device is particularly suitable for multi-angle, high-precision scanning of workpieces with regular shapes and six scanning surfaces.

[0033] In this embodiment, the supporting base 101 is the basic structural part of the entire device, used to stably support the other components, and is provided with two parallel guide rails. The guide rails are arranged in the front-to-back direction to guide the conveying mechanism to slide along its direction.

[0034] In this embodiment, the transport mechanism is positioned above the support base 101. Its core components include a front-to-back moving module 102, lifting guide rails 103, a lifting carriage 104, and a load-bearing arm assembly 105. The front-to-back moving module 102 includes a sliding base and a drive motor assembly. The sliding base slides along the guide rails on the base via a slider assembly located at its lower part, allowing the entire transport mechanism to move along the front-to-back direction of the base. The lifting guide rails 103 are two linear guide rails vertically mounted on the columns on both sides of the front-to-back moving module 102. The lifting carriage 104 slides along the guide rails via a slider, enabling it to move vertically up and down, ensuring the height adjustment and positioning accuracy of the workpiece during transport.

[0035] In this embodiment, the lifting carriage 104 is equipped with a load-bearing arm assembly 105, which includes two symmetrically arranged fork arms. The fork arms are fixed to the lifting carriage 104 and can be inserted under the support handle of the hexahedral workpiece to stably support the workpiece from both sides. This structure ensures the workpiece remains stable during transport, preventing swaying and facilitating subsequent high-precision scanning operations.

[0036] In this embodiment, the four-dimensional scanning component 106 is mounted on the central platform above the support base 101, specifically suspended on the intermediate connecting frame between the lifting guide rails 103. This component mainly includes a rotating device and multiple scanning heads. The rotating device is mounted below the hexahedral workpiece and consists of a high-precision electric rotating mechanism, capable of driving multiple scanning heads to rotate around the workpiece. The scanning heads scan around the bottom surface and four vertical sides of the workpiece along a set trajectory, acquiring complete boundary geometric information and structural data.

[0037] In this embodiment, the rotating device is located below the hexahedral workpiece and is suspended between the lifting guide rails 103 via a central platform. After the workpiece is lifted into place by the load-bearing arm assembly 105, the drive mechanism in the rotating device is activated, causing the rotating bracket to rotate around the central axis of the workpiece. The scanning heads mounted on the mounting frame move around the workpiece during rotation. During rotation, each scanning head maintains its own scanning angle, relying on the overall rotation of the rotating bracket to complete omnidirectional coverage, achieving continuous scanning of the four vertical sides and the bottom surface of the workpiece.

[0038] In this embodiment, the two-dimensional scanning component is mounted on the uppermost support frame of the device. This component includes a support beam and an inverted XY platform mounted below it. The XY platform has a typical cross structure, with both the X and Y axes composed of linear guide rail modules. Its cross carriage 107 is mounted below the support beam, enabling the scanning head to move forward and backward and left and right in the horizontal direction. The scanning head is mounted at the lower end of the XY platform and is used to scan the top surface of a hexahedral workpiece. Under the guidance of the control system, the XY platform moves along a set trajectory to ensure that the scanning head covers the entire top area.

[0039] In practical operation, the user places the hexahedral workpiece in the pick-and-place position of the device. The handling mechanism is activated, extending the load-bearing arm assembly 105 into the bottom of the workpiece's support handle and stably lifting the workpiece to the designated scanning position. Subsequently, the four-dimensional scanning assembly 106 is activated, and the rotating device drives the scanning head to rotate around the workpiece, acquiring image data of the bottom and four sides of the workpiece. Finally, the XY platform of the two-dimensional scanning assembly drives the scanning head to cover and scan the entire top surface.

[0040] Throughout the scanning process, the data acquired by each scanning head is uploaded in real time to the data processing unit for storage and subsequent 3D modeling operations. This enables efficient, stable, and accurate omnidirectional scanning of hexahedral workpieces.

[0041] Through the structural design shown in the above embodiments, the present invention achieves all-round, high-efficiency scanning of regular hexahedral workpieces, which not only improves the automation level of industrial scanning, but also greatly improves the integrity and accuracy of scanning data, and is applicable to multiple high-precision manufacturing fields such as electronic manufacturing, machining, and mold inspection.
