Problems solved by technology

The current existing technology is manually scanned by the tester using a barcode scanner. This method has three disadvantages: 1. Manual scanning needs to be manually aligned with the barcode on the circuit board placed in the test tooling, sometimes it is not easy to align 2. Sometimes there will be manual scanning errors, such as scanning the SN barcode to the MAC barcode box, or on the contrary, it needs to be re-scanned; 3. Sometimes it will appear that the board A Scan the barcode to the barcode of board B, causing the faulty board to be regarded as a qualified board and flow to the next process
[0003] In the prior art, there are also barcode scanning guns or scanning modules installed on the rack of the production line to automatically scan the barcode position of the product; some scan guns or scanning modules are installed on movable brackets and set on test fixtures. Next to it, manually scan or automatically scan the barcode position of the product. In these solutions, the scanning gun or scanning module is hung outside the test tool, not on the test tool body. There are the following disadvantages: 1. In actual use, sometimes due to Personnel collided by mistake, and the deviation caused scanning abnormality, and the position needs to be readjusted; 2. Sometimes the scanning gun or scanning module shakes due to the vibration of the production line frame, which affects the scanning; 3. In serious cases, it sometimes falls to the ground and is damaged , causing a line stop

[0033] like Figure 2 to Figure 4 As shown, a pit groove 11 is dug and milled on the pressure plate 1, and a fixed slide rail 7 and a small push-pull electromagnet 8 are fixedly arranged in the pit groove 11. A movable slide rail 71 is arranged on the fixed slide rail 7, and the movable slide rail 71 slides linearly on the fixed slide rail 7, the guide rod 81 of the small push-pull electromagnet 8 is movably connected with one end of the movable slide rail 71 through the clip pin 83, and a magnet 9 is pasted on the scanning module 5, and is adsorbed to the iron by the magnet 9. On the moving slide rail 71 made.

[0034] In this embodiment, the detachable connection between the scanning module 5 and the moving slide rail 71 is by pasting a magnet 9 on the scanning module 5 and attracting it to the iron moving slide rail 71 . In practice, other detachable connection methods can also be used, for example: an iron sheet can be pasted on the scanning module 5, and a magnet can be ...

[0043] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that there are two fixed slide rails 7 and two movable slide rails 71, and the rest of the structure is the same as that of the first embodiment. This embodiment is suitable for situations where the scanning module 5 is relatively large and heavy.

[0045] like Image 6 and Figure 7 As shown, two pits 11 are dug and milled on the pressing plate 2, and a scanning module 5 is arranged in each pit 11. The two scanning modules 5 are respectively fixed at position A and position B, directly above the barcode on the main board 2 to be tested, position A is aligned with the SN barcode, and position B is aligned with the MAC barcode.

[0046] A magnet 9 is pasted on the installation surface of each scanning module 5, and iron sheets 10 are all arranged in the two pits 11; Iron sheet 10 on.

[0047] In this embodiment, the detachable connection between the scanning module 5 and the pit 11 is by sticking the magnet 9 on the scanning module 5 and attracting to the iron sheet 10 in the pit 11 . In practice, other detachable connection methods can also be used, for example, magnets can also be pasted on the scanning module 5, and the detachable connection can be realized through the adsorption of two magnets. It is also possible ...

Abstract

An intelligent control test tool for multi-bar-code automatic scanning comprises a pressing plate located above a tested mainboard, and a pin board located below the tested mainboard, wherein the tested mainboard is further connected to test equipment. A pit slot is formed in the pressing plate, and one or more detachably connected scanning modules are arranged in the pit slot; the scanning moduleis electrically connected with the test equipment, and the scanning module is arranged right above the bar code on the tested mainboard; a touch switch is arranged on the needle plate and is electrically connected with the test equipment; and when the pressing plate is pressed downwards until the tested mainboard tightly presses the needle plate, the touch switch is closed under the pressure of the tested mainboard, and the test equipment is triggered to control the scanning module to scan the corresponding bar code. The bar code is automatically scanned, and the production efficiency is improved; the scanning modules can be shared, when the test tool is replaced, the scanning modules are taken down and placed on a new test tool, and use is convenient.

Description

【Technical field】 [0001] The invention belongs to the technical field of testing equipment, and specifically refers to an intelligent control testing tool for automatic scanning of multiple barcodes. 【Background technique】 [0002] When testing circuit boards of products such as set-top boxes and servers, it is necessary to scan the serial number SN barcode and MAC barcode of the motherboard. The current existing technology is manually scanned by the tester using a barcode scanner. This method has three disadvantages: 1. Manual scanning needs to be manually aligned with the barcode on the circuit board placed in the test tooling, sometimes it is not easy to align 2. Sometimes there will be manual scanning errors, such as scanning the SN barcode to the MAC barcode box, or on the contrary, it needs to be re-scanned; 3. Sometimes it will appear that the board A Scan the barcode to the barcode of board card B, causing the faulty board to be regarded as a qualified board and flo...
