Description

Technical Field

[0001] This utility model relates to the field of scanning and inspection technology, specifically a rotating scanning platform fixture for a handheld 3D laser scanner. Background Technology

[0002] When using a handheld 3D laser scanner to scan a product, the product needs to be positioned and cannot move. To ensure the scanner can completely scan all surfaces of the product, the operator must not only hold the scanner and move it around the product in circles (up, down, left, and right), but also move around the product accordingly (scanning one product takes about 20 minutes on average, with the operator circling the scanner about 5 times). Prolonged operation leads to hand fatigue and exhaustion. Furthermore, to ensure the accuracy of the scan results and calculations, a certain number of positioning dots must be pasted onto the scanning plane before using a point-based handheld 3D laser scanner. Since the products being scanned are often not at the same station or inspection position, positioning dots must be pasted onto the current scanning plane before each scan, and then cleaned afterward. Although the positioning dots can be reused, their adhesion, flatness, and integrity decrease significantly after several uses. Therefore, this method of pasting positioning dots is time-consuming, labor-intensive, and results in significant wear and tear.

[0003] Therefore, it can be seen that handheld 3D laser scanners, under traditional usage, will consume a lot of the operator's physical strength, time and consumable costs. In particular, when used as a means of inspecting the shape and size of products, the detection efficiency is low and the production cycle is affected. Utility Model Content

[0004] The purpose of this invention is to provide a rotating scanning platform fixture for a handheld 3D laser scanner to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotating scanning platform fixture for a handheld 3D laser scanner, comprising a working platform and a rotating base disposed below the working platform.

[0006] The work platform includes a shelf, handles, and reflective dots. The handles are located on the sides of the shelf, and the reflective dots are located on the front. Several handles and reflective dots are provided. The shelf is used to place the product to be scanned, and the reflective dots serve to reflect light, facilitating scanning with a handheld 3D laser scanner. The handles allow the operator to easily rotate the shelf. Reflective dots are located on the front, but not on the reverse side, to accommodate both reflective and non-reflective handheld 3D laser scanners.

[0007] The rotating base includes an outer ring, an inner ring, noise-absorbing strips, and steel balls. The inner and outer rings are concentrically arranged. The noise-absorbing strips and steel balls are positioned between the inner and outer rings, with a plurality of strips and balls arranged alternately. Several anti-slip pads are positioned above the inner ring, and the platform rests on these pads. The steel balls allow the inner and outer rings to rotate relative to each other. The noise-absorbing strips reduce wear during rotation, and the anti-slip pads prevent the circular platform from sliding or falling off the rotating base.

[0008] As a preferred embodiment of this utility model, the storage platform is a disc, and the circular work platform is mainly convenient for workers to use.

[0009] As a preferred embodiment of this utility model, the handle is made of stainless steel, and several handles are arranged in a circular array on the platform for continuous rotation of the circular platform.

[0010] As a preferred embodiment of this utility model, the handle is cylindrical, and the cylindrical handle is mainly for the convenience of workers to grip.

[0011] As a preferred embodiment of this invention, the platform, outer ring, and inner ring are all made of aluminum alloy, which is not only lightweight but also has high strength.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention solves the problem of hand fatigue and hand soreness caused by operators having to hold the scanner and move it in circles around the product when performing scanning operations with a handheld 3D laser scanner by turning the handle on the work platform.

[0014] This invention solves the problem of wasting manpower and resources by setting reflective dots on the work platform, which requires applying dots to the current scanning plane each time scanning at different workstations and cleaning the dots after each scan.

[0015] The working platform and rotating base of this utility model are characterized by stable rotation, appropriate size, convenient movement, quick installation, and simple operation. Attached Figure Description
