Description

Marking device for testing vehicle frame

Technical Field

The utility model relates to a visual detection equipment technical field, in particular to frame test marking device.

Background

Some appearance parts generally need to be subjected to precise appearance detection before leaving a factory, such as detection of a vehicle frame on a vehicle body. For appearance detection, a mechanical arm is usually required to drive the 3D vision sensor to test, and the two-dimensional code is additionally used for binding. In the past, only a detection device is arranged on the equipment, and the two-dimensional code can be marked only after a product is moved out of a detection position, so that the process has confusion risk.

There is therefore a need for an improved apparatus to address the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a frame test marking device can beat the mark immediately after the test and bind to the product.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a frame test marking device, includes the fixed tool of product and is located the testing arrangement of the fixed tool one side of product, testing arrangement includes arm and the 3D visual sensor who is located the arm free end, be equipped with marking machine on the fixed tool of product, marking machine can be at X to remove module and Y to the drive translation down of removing the module.

Specifically, the periphery of the 3D vision sensor is provided with a target, the target is provided with a target framework, and each node of the target framework is provided with a plurality of reflectors, so that a tracking device matched with the reflectors is arranged on the side of the testing device.

Furthermore, two tracking probes overlooking the target are arranged at the top end of the tracking device.

Adopt above-mentioned technical scheme, the utility model discloses technical scheme's beneficial effect is:

this equipment can acquire product information with 3D vision sensor to mark immediately and bind the detection data, avoid the product to remove the back and mark and cause the information to obscure.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 and 2, the utility model discloses a frame test marking device, including the fixed tool 1 of product and the testing arrangement 2 that is located the fixed tool 1 one side of product, testing arrangement 2 includes arm 21 and the 3D visual sensor 22 that is located the arm 21 free end, is equipped with marking machine 3 on the fixed tool 1 of product, and marking machine 3 can be at X to removing module 31 and Y to the drive translation under the module 32 that removes. The robotic arm 21 controls the proximity and orientation of the 3D vision sensor 22 towards the product 5. The X-direction moving module 31 and the Y-direction moving module 32 are used to control the movement of the marking machine 3, so as to avoid blocking the detection view angle of the 3D vision sensor 22. This equipment can be earlier acquireed the product 5 information that is fixed in on the fixed tool 1 of product with 3D vision sensor 22 to marking on 5 surfaces of product with marking machine 3 immediately will detect data binding, and it causes the information to obscure to avoid the product to remove the back mark.

As shown in fig. 1 and 3, a target 23 is disposed at the periphery of the 3D vision sensor 22, the target 23 has a target skeleton 231, a plurality of reflective mirrors 231 are disposed at each node of the target skeleton 231, and a tracking device 4 matched with the reflective mirrors 231 is disposed at the side of the testing device 2. The mirror 231 reflects the light from the tracking device 4 so that the actual position of the 3D vision sensor 22 can be accurately captured by the tracking device 4, and thus the spatial position of the 3D vision sensor 22 and hence the position parameter detected by the product 5 can be determined with reference to the tracking device 4.

As shown in fig. 1, two

tracking probes

41 and 42 of the overhead target 23 are provided at the tip of the tracking device 4. The two

tracking probes

41, 42 simulate the human eyes and thus determine the spatial position of the target 23 and hence the 3D vision sensor 22.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
