Problems solved by technology

In the prior art, the production of boards includes multiple processes, and it is necessary to measure the products after each process, while the existing ones are generally manual visual inspection, and there are further automatic inspections of multiple stations, and this automatic inspection The equipment has different detection stations and detection methods for different processes. The bulky, complex structure, complex retrieval process, and many fault points are no longer suitable for the current needs of mass and rapid production.
Secondly, spacers are often set between the plates to be tested. When the manipulator takes out the plates and spacers from the silo, in order to avoid the occurrence of wrong materials, it is necessary to accurately distinguish the plates and spacers. The most common way to distinguish is through manual observation, which is not only inefficient, but also prone to material picking errors due to operator fatigue; in addition, see figure 1 At the same time, the detection equipment developed for rectangular layout requires multiple sets of guide rails and multiple sets of air floating platforms, which increases the cost
Finally, boards often need to be inspected on both sides, while existing inspection equipment needs to be manually turned over
The above problems seriously affect the production quality of the panels and the layout of the site, which cannot meet the production requirements

no. 1 example

[0029] An intelligent loop detection device, see figure 2 , the equipment includes a feeding ring 100, and along the feeding ring 100, an upper bin module 1, a positive inspection optical assembly 5, a flipping module 6, an adapter arm 7, a reverse inspection optical assembly 8, The coding module 9, the unloading arm 10 and the unloading bin module 11 are used to realize loading, front-side measurement, 180° flip, reverse-side measurement, coding marking and unloading of the plate to be tested.

[0030] A material type judging module 3 is arranged directly above the feeding bin module 1 for detecting and judging the feeding type supplied by the feeding bin module 1 .

[0031] Between the upper bin module 1 and the lower bin module 11, a loading arm 2 and a spacer connecting module 4 are arranged, and the loading arm 2 is used to pick up and transfer the plate to be tested and / or the spacer The spacer connecting module 4 is used to separate the spacer absorbed by the bottom s...

no. 2 example

[0048] Unlike the first embodiment, see image 3 A dedusting module 12 is arranged upstream of the positive inspection optical assembly 5 and the reverse inspection optical assembly 8 for removing dust from the board before inspection, so as to ensure the accuracy of board quantity detection.

[0049] The dust removal module 12 adopts an air knife of a fan-shaped blowing mechanism, and may also use a sticky dust roller or the like.

no. 3 example

[0051] Unlike the first embodiment, see Figure 4 , The lower bin module 11 includes a qualified product lower bin 111 and a defective product lower bin 112 for receiving qualified products and defective products. For this embodiment, the corresponding loading arm 2 will add one step of work, that is, normally, the separator paper is directly transported from the upper bin module 1 to the qualified product lower bin 111, but when it is detected as an NG board, It is necessary to transport the separator paper in the qualified product lower bin 111 to the defective product lower bin 112 . Or set up a separate paper supply bin to supply it. Then the defective product boards are transported to the defective product lower silo 112 .

Abstract

The invention provides an intelligent loop detection device and a detection method. The device includes a feeding ring, along which a feeding bin module, a positive inspection optical component, a turning module, and a transfer ring are sequentially arranged circularly. Arm, reverse inspection optical assembly, inkjet module, unloading arm and unloading bin module to realize loading, front measurement, 180° flip, backside inspection, inkjet marking and unloading of the board to be tested . This application integrates automatic processes such as paper separation, front inspection, reverse inspection, coding and dust removal of the board to be tested on the circular conveying line, which reduces the equipment space and improves the detection efficiency and accuracy. Popularization and application of inspection of board products including circuit boards.

Description

technical field [0001] The invention relates to the technical field of detection based on machine vision, in particular to an intelligent loop detection device and a detection method. Background technique [0002] Board products such as circuit boards, glass cover plates for 3C products, and photovoltaic silicon wafers are currently widely used in electronic and electrical equipment. In the prior art, the production of boards includes multiple processes, and it is necessary to measure the products after each process. However, the existing manual inspection is generally performed by naked eyes, and there are further automatic inspections of multiple stations. This automatic inspection The equipment has different detection stations and detection methods for different processes. It is bulky, complex in structure, complex in retrieval process, and has many fault points. It is no longer suitable for the current needs of mass and rapid production. Secondly, spacers are often set ...
