Description

Technical Field

[0001] This utility model belongs to the field of busbar detection technology, specifically a non-contact measuring device for electrically controlled busbars. Background Technology

[0002] Electrical control busbars are highly conductive components that replace traditional wires for current collection and distribution. They are primarily made of copper or aluminum structural parts or sheet metal and have strict requirements for three-dimensional dimensions. Therefore, three-dimensional measurements are necessary after manufacturing. Traditional methods involve contact measurements, such as coordinate measuring machines, inspection gauges, and measuring probes. However, contact measurements can easily cause deformation of the product under test, leading to measurement errors and the risk of scratches.

[0003] In addition, the industry already has non-contact measurement solutions. These employ a high-precision moving platform and a 2D laser line scan camera. This measurement method places extremely high demands on the measurement platform, as the distance between the line scan camera and the measurement platform affects measurement accuracy. This, in turn, limits its widespread application. Utility Model Content

[0004] Purpose of this utility model: This utility model uses a 3D line-scan laser measuring instrument for non-contact measurement, primarily addressing the problems of deformation and scratches inherent in contact measurements. It also solves the issue of high requirements for the measurement platform in 2D line-scan solutions. With a simple actuation mechanism, it eliminates the need for a high-precision measurement platform, enabling the three-dimensional measurement of electrical control busbars. This saves costs and solves the problem of measurement accuracy.

[0005] The technical solution of this utility model is as follows: the non-contact measuring device for electric busbars includes a workbench and a measuring platform, wherein the measuring platform is used to install the busbars.

[0006] The non-contact measurement equipment for electrical control busbars also includes: a 3D line-scan laser measuring instrument, a measuring moving device, a platform moving device, and a measuring host.

[0007] The measuring moving device and the platform moving device are installed on the workbench. The 3D line-scanning laser measuring instrument is set above the busbar. The 3D line-scanning laser measuring instrument is installed on the measuring moving device. The measuring platform is installed on the platform moving device. The 3D line-scanning laser measuring instrument, the measuring moving device, and the platform moving device are connected to the measuring host.

[0008] The measuring moving device and the platform moving device include: a linear moving mechanism and two guiding mechanisms.

[0009] The busbar is provided with multiple detection areas. The measuring moving device is used to drive the 3D line scan laser measuring instrument to move laterally, and the platform moving device is used to drive the measuring platform to move longitudinally, so that the 3D line scan laser measuring instrument can scan the multiple detection areas on the busbar. When the 3D line scan laser measuring instrument moves above the detection area, the 3D line scan laser measuring instrument scans the height information of the detection area and sends the height information to the measuring host.

[0010] In a further embodiment, the measuring moving device includes: a mounting frame, a first linear power mechanism, two first guide mechanisms, a connector, and a mounting component.

[0011] The mounting bracket is mounted on the workbench, the first linear power mechanism and the two first guide mechanisms are mounted on the mounting bracket, the connector is mounted on the first linear power mechanism and the two first guide mechanisms, the mounting component is mounted on the connector, and the 3D line scan laser measuring instrument is mounted on the mounting component.

[0012] The first linear power mechanism and the two first guide mechanisms are arranged to extend in the lateral direction.

[0013] In a further embodiment, the platform moving device includes: a second linear power mechanism and a second guiding mechanism.

[0014] The second linear power mechanism and two second guide mechanisms are mounted on the worktable, the positioning plate is mounted on the second linear power mechanism and two second guide mechanisms, and the positioning fixture is mounted on the positioning plate.

[0015] The second linear power mechanism and the two second guide mechanisms are arranged to extend in the longitudinal direction.

[0016] In a further embodiment, the measurement platform includes a positioning plate and a positioning fixture.

[0017] The positioning plate is mounted on the second linear power mechanism and the two second guide mechanisms, and the positioning fixture is mounted on the positioning plate.

[0018] In a further embodiment, the positioning fixture includes a lifting cylinder and a clamping block.

[0019] The lifting cylinder is mounted on the positioning plate, and the clamping block is mounted on the lifting cylinder.

[0020] In a further embodiment, the lifting cylinder is a rotary clamping cylinder, which can rotate the clamping block after it rises to a predetermined position, thus opening up the installation position of the busbar and facilitating the installation of the busbar.

[0021] In a further embodiment, the positioning fixture further includes a positioning block, which is mounted on a positioning plate and has a guide portion. The positioning block is used to insert into the busbar and can limit the horizontal direction of the busbar. The guide portion facilitates the installation of the busbar.

[0022] In a further embodiment, the linear power mechanism is one of a lead screw mechanism and an electric cylinder.

[0023] In a further embodiment, the guiding mechanism is a slider guide mechanism.

[0024] The beneficial effects of this utility model are as follows: By installing the 3D line-scanning laser measuring instrument on a measuring moving device with one linear movement mechanism and two guiding mechanisms, and installing the measuring platform on a platform moving device with one linear movement mechanism and two guiding mechanisms, the 3D line-scanning laser measuring instrument can be inspected in multiple areas and the measuring platform can be moved longitudinally by controlling the running accuracy of the 3D line-scanning laser measuring instrument alone. This achieves the three-dimensional measurement of the electrical control busbar. Compared with the existing 2D line-scanning scheme, which requires strict control of the distance accuracy between the 2D laser line-scanning camera and the measuring platform used to install the busbar, this greatly reduces the difficulty of accuracy control, saves costs, and solves the problem of measurement accuracy.

[0025] By combining the 3D line-scan laser measuring instrument with the host software stored in the measuring host, the software in the measuring host can perform calculations and processing on the data. That is, according to the four-point plane fitting method of three-dimensional measurement, after fitting the plane, the height of other key positions is measured, and other plane dimensions are calculated. By comparing with the standard, a judgment is made on whether the three-dimensional dimensions of the product meet the standard. This process does not contact the busbar, which solves the deformation and scratch problems existing in traditional contact measurement. Attached Figure Description

In a preferred embodiment, the busbar is provided with at least four detection areas.

The software processes the data, fitting a plane using the four-point plane fitting method of three-dimensional measurement, and then measures the height of other key locations. Simultaneously, it calculates other planar dimensions, compares them with standards, and determines whether the product's three-dimensional dimensions meet the standards.
