Description

Technical Field

[0001] The invention relates to the technical field of printed circuit board production, in particular to a detection structure with the effect of correcting and preventing deviation. Background Art

[0002] Printed circuit board {PCB circuit board}, also known as printed circuit board, is the provider of electrical connections for electronic components. It has a history of more than 100 years; its design is mainly layout design; the main advantage of using circuit boards is that it greatly reduces wiring and assembly errors, improves the level of automation and production labor rate, and requires punching, patching or packaging during the production and processing of circuit boards. In order to ensure the accurate processing and collection of circuit boards, their positions need to be detected.

[0003] For example, the utility model with application number CN202221416954.7 relates to the technical field of integrated board drilling, and is used to solve the problem that the drilling device cannot clamp and position integrated boards of different sizes, and cannot collect fallen waste. It is specifically a 5G integrated circuit board anti-offset drilling device, including a base. The utility model slides the slider at the lower end of the support block inside the slide groove, and adjusts the spacing of the support blocks by a screw to match integrated boards of different lengths. At the same time, the integrated board is inserted into the clamping groove by the cooperation between the clamping rod and the clamping plate, and is fixed by the clamping plate and the extrusion spring to prevent the integrated board from being offset during drilling, thereby improving the accuracy of the device during drilling, and the cooperation between the second storage box and the first storage box can facilitate the recycling of waste and reduce the labor intensity of later staff during cleaning. However, during the production of circuit boards, the detection mechanism and the correcting structure generally need to be taken out one by one for use, resulting in the need to store the detection mechanism and the correcting structure one by one again after punching, mounting or packing during the production and processing of the circuit boards. This makes it inconvenient to move and protect the detection mechanism and the correcting structure during assembly and transportation with other circuit board production and processing equipment.

When the slide seat 12 moves horizontally about the top of the auxiliary frame 4, it can synchronously drive the built-in gear 140 1. The connecting slide plate 1402, the adapter plate 1403 and the correction plate 1404 move in the built-in groove 15, so that when the visual inspection head 204 is used to perform visual inspection and find that the circuit board is offset relative to the working platform, the position of the slide 12 is moved to drive the adapter plate 1403 and the correction plate 1404 to move, so that the position of the circuit board placed on the working platform can be corrected. In addition, through the movement of the slide 12, the built-in gear 1401 will contact and mesh with the built-in rack 13, so that the built-in gear 1401 will rotate.

Similarly, the rotation of gear 1 802 will drive the gear 2 806 meshing with it to rotate, so that through the rotation of gear 1 802 and gear 2 806, the cleaning brush 804 on the outer surface of gear 1 802 and gear 2 806 will rotate synchronously, so that the visual inspection head 204 on the outer surface of the cleaning brush 804 can be cleaned, so that the visual inspection head 204 can be visually inspected again, and dust can be prevented from blocking the visual inspection of the visual inspection head 204. In addition, the design of the protective cover 9 can provide semi-hidden protection for the driving wheel 801, gear 1 802 and gear 2 806.

[0025] In summary, if Figure 1-Figure 6As shown, the detection structure with the effect of correcting and preventing deviation is convenient to be placed on the outside of the platform of the production and processing equipment through the design of the upper mounting plate 601 and the lower mounting plate 602 when in use. At the same time, the upper mounting plate 601 and the lower mounting plate 602 can be fixed to the outside of the platform by the design of the threaded hole 603 and the bolt. Then, when the auxiliary frame 4 is slid to a certain position, the slide plate 5 is engaged and fixed with the built-in frame 3, which is conducive to detection and anti-deviation processing. Then, the visual detection head 204 is a visual detection camera, which determines whether the position of the circuit board on the working platform is offset through visual detection. The design of the support rod 202 and the connecting rod 203 is used to provide support for the visual detection head 204, which is convenient to be on the working platform. The servo motor 10 is designed to drive the driving screw 11 to rotate, and the rotation of the driving screw 11 can drive the slide 12 threadedly connected thereto to move horizontally. When the slide 12 moves horizontally about the top of the auxiliary frame 4, it can synchronously drive the built-in gear 1401, the connecting slide 1402, the adapter plate 1403 and the correction plate 1404 to move in the built-in groove 15, so that when the visual inspection head 204 is used to perform visual inspection and it is found that the circuit board is offset relative to the working platform, the position of the slide 12 can be moved to drive the adapter plate 1403 and the correction plate 1404 to move, so that the circuit board placed on the working platform can be corrected. In addition, the position of the slide 12 is moved. The built-in gear 1401 will contact and mesh with the built-in rack 13, so that the built-in gear 1401 will rotate, and the adapter plate 1403 and the correction plate 1404 connected to the built-in gear 1401 will rotate synchronously, which is beneficial to adjust the correction position of the adapter plate 1403 and the correction plate 1404 with respect to the circuit board. At the same time, the rotation design of the correction plate 1404 can be used to make the bottom of the correction plate 1404 abut against the outer surface of the circuit board to ensure that the position of the circuit board remains stable during the production and processing of the circuit board to avoid deviation. Secondly, when the adapter plate 1403 and the correction plate 1404 are not needed, the correction plate 1404 can be rotated to be in the upper area of ​​one side of the auxiliary frame 4, and finally the detection component 2 is stored in the rubber pad 16. After the side outer surface is rotated so that the correction plate 1404 is in the upper area of ​​one side of the auxiliary frame 4, the rotation of the driving screw 11 can synchronously drive the driving wheel 801 to rotate, and the rotation of the driving wheel 801 can drive the gear 1 802 meshing with it to rotate. Similarly, the rotation of gear 1 802 will drive the gear 2 806 meshing with it to rotate, so that through the rotation of gear 1 802 and gear 2 806, the cleaning brush 804 on the outer surface of gear 1 802 and gear 2 806 will rotate synchronously, so that the visual inspection head 204 on the outer surface of the cleaning brush 804 can be cleaned, so as to facilitate the visual inspection operation of the visual inspection head 204 again, and avoid dust blocking the visual inspection of the visual inspection head 204.
