Abstract
Description
Technical Field
[0001] This invention relates to the field of visual inspection technology, specifically to a tooling for placing parts and a method of using it. Background Technology
[0002] In the automotive industry, tooling for component placement mainly falls into three categories. The first category consists of standard tooling used for dimensional inspection / measurement, including gauges, PCFs, or UCFs. The second category comprises tooling used for transfer and storage; this type of tooling, also known as containers, typically only needs to ensure easy access to parts and prevent deformation. The third category is custom-made tooling tailored to user needs, such as flexible tooling for optical scanning. Machine vision, as an emerging discipline, previously relied on either on-site production resources or small samples for tasks such as optical path design, imaging verification, and sample collection. However, the stringent requirements of paint shops, such as explosion-proof and high-cleanliness standards, impose many additional conditions on on-site verification / design work. Furthermore, using small samples for optical path design and sample collection results in significant discrepancies compared to on-site imaging conditions, leading to distorted results. Summary of the Invention
[0003] The purpose of this invention is to provide a tooling and method for placing parts, which is used to simulate the assembly state of parts on a vehicle during visual inspection, so as to realistically restore the actual assembly position of parts on the vehicle, thereby maximizing the accuracy of the early optical path design and imaging verification.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0005] A tooling for placing parts includes a main frame, a side lifting mechanism, and a top lifting mechanism. The main frame includes a support beam and a top crossbeam located at the top of the support beam. The side lifting mechanism and the top lifting mechanism are movably connected to the top crossbeam. The side lifting mechanism and the top lifting mechanism can move along the length direction of the top crossbeam and can rotate around the top crossbeam.
[0006] When performing visual inspection on the part to be tested, the part to be tested is placed on the side support mechanism and / or the top support mechanism. By adjusting the position of the side support mechanism and the top support mechanism, the assembly state of the part to be tested on the whole vehicle is simulated.
[0007] Based on the above technical means, by setting up a main frame and setting up a side support mechanism and / or top support mechanism for placing parts on the main frame, and by adjusting the position of the side support mechanism and the top support mechanism, the actual assembly state of the parts on the whole vehicle can be realistically simulated. This not only improves the efficiency of visual inspection of parts, but also effectively ensures the accuracy of the early optical path design and imaging verification of parts. It also has the advantages of simple structure, convenient operation and low cost.
[0008] Preferably, the side support mechanism includes a support member, a sleeve disposed at one end of the support member, and a pin limiting block. The support member has multiple pin holes spaced apart along its length. By adjusting the position of the pin limiting block on the support member, the height of the part to be tested can be adjusted. The positioning of the part to be tested is achieved by the cooperation between the pin limiting block and the pin holes. The sleeve is fitted onto the top crossbeam.
[0009] By setting a sleeve at one end of the support member for fitting onto the top crossbeam, the side lifting mechanism can move along the length of the top crossbeam.
[0010] Preferably, the support member has a snap-fit limiting structure hinged on the side away from the part to be tested, and the support beam has a central crossbeam in the middle of its length direction. The angle of the part to be tested can be adjusted by the cooperation of the snap-fit limiting structure and the central crossbeam.
[0011] Preferably, the snap-fit limiting structure includes a fixing component fixedly connected to the support member and a snap-fit limiting component hinged to the fixing component. The snap-fit limiting component has multiple arc-shaped portions along its length that engage with the central crossbeam.
[0012] Preferably, the support member has anti-collision pads on the side near the part to be tested and at the part of the pin limiting block that is in contact with the part to be tested.
[0013] Preferably, the top support mechanism includes a support rod, a hinge component connected to the support rod, and a buffer component disposed on the support rod, wherein the hinge component is fitted onto the top crossbeam.
[0014] Preferably, the support rod has a U-shaped structure, with the hinge components rotatably connected to both ends, and the buffer component is provided at the bottom. The buffer component can be rotated in or out relative to the support rod to adjust the angle of the part to be measured.
[0015] Preferably, the main frame includes four support beams, wherein two of the support beams have a top crossbeam at their top and a middle crossbeam in their middle, and the other two support beams have another top crossbeam at their top and another middle crossbeam in their middle. Each of the two top crossbeams has two side lifting mechanisms, one end of which is connected to one of the top crossbeams and the other end of which is connected to the other top crossbeam.
[0016] The present invention also provides a method for using the tooling described herein for placing parts, comprising the following steps:
[0017] Based on the vehicle data, obtain the height of the part under test above the ground and the angle formed with the ground;
[0018] Based on the assembly status of the part to be tested on the vehicle, place the part to be tested in the corresponding position of the tooling.
[0019] By adjusting the position of the side support mechanism and / or the top support mechanism, the height of the part under test above the ground and the angle formed with the ground are made consistent with the state of the part under test on the whole vehicle, and then the visual inspection of the part is performed.
[0020] Preferably, the height of the part to be tested above the ground is adjusted by a pin limiting block and / or a support rod; the angle between the part to be tested and the ground is adjusted by a snap-fit limiting structure and / or a buffer component and / or a support rod.
[0021] The beneficial effects of this invention are:

By adjusting the positions of the side support mechanism 2 and the top support mechanism 3, the assembly state of the part to be tested on the whole vehicle is simulated.
[0040] The side-supporting mechanism 2 includes a support member 21, a sleeve 22 located at one end of the support member 21, and a pin-limiting block 23. The support member 21 has multiple pin holes 24 spaced apart along its length. By moving the pin-limiting block 23, the pin-limiting block 23 engages with different pin holes 24 along the length of the support member 21, thereby achieving height adjustment and positioning of the part to be measured.

A through hole 323 is formed on the sliding part 321 for the top crossbeam 12 to pass through, so that the support member 21 can slide in the length direction of the top crossbeam 12 to adjust the position of the part to be measured. The sliding part 321 and the hinge part 322 are integrally formed.

The other two support beams 11 have another top crossbeam 12 at their top and another middle crossbeam 13 in the middle. Each of the two top crossbeams 12 has two side support mechanisms 2. One end of each top support mechanism 3 is connected to one of the top crossbeams 12, and the other end is connected to the other top crossbeam 12. A reinforcing beam 14 is provided between the two support beams 11 located at the same end of the two top crossbeams 12 to ensure the strength and stability of the main frame.
