Character 2D code detection device

Abstract

The invention discloses a character 2D code detection device. The character 2D code detection device comprises a rack, a feeding material disk caching mechanism, a discharging material disk caching mechanism, a suction cup mechanism, a detection mechanism and an NG product getting mechanism. The feeding material disk caching mechanism and the discharging material disk caching mechanism are fixed to the left and right sides of the rack correspondingly. The detection assembly is fixed to the middle area of the rack. The suction cup mechanism is fixed to the feeding material disk caching mechanism, the discharging material disk caching mechanism and the detection mechanism and located above a to-be-detected assembly. The NG product getting mechanism is fixed to the location behind the suctioncup mechanism. The character 2D code detection device conducts large-area detection on a whole material disk through a high-precision large-view CCD camera and effectively improves the detection efficiency and the product detection accuracy. The mechanisms are driven to act through a motor used in cooperation with a lead screw and linear guide rails or a cylinder used in cooperation with the linear guide rails, and the requirements for stability and position accuracy in the motion process are ensured; the feeding or discharging waiting time can be effectively reduced through the feeding material disk caching mechanism and the discharging material disk caching mechanism, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of detection equipment for electronic products, in particular to a character two-dimensional code detection equipment. Background technique [0002] With the miniaturization, integration and personalization of electronic products, the requirements for product appearance and traceability are getting higher and higher. In the production of electronic products, it is required to use high-precision testing equipment to identify and screen the marks on the product appearance, so as to Control the production process, such as flexible circuit boards in the electronics industry. The production process of flexible circuit boards contains silk screen characters and or spray-printed two-dimensional codes to play the role of identification and traceability. The original character detection method is artificial. However, for the same series of products with different material numbers or different batches that are very similar in a...

[0002] With the miniaturization, integration and personalization of electronic products, the requirements for product appearance and traceability are getting higher and higher. In the production of electronic products, it is required to use high-precision testing equipment to identify and screen the marks on the product appearance, so as to Control the production process, such as flexible circuit boards in the electronics industry. The production process of flexible circuit boards contains silk screen characters and or spray-printed two-dimensional codes to play the role of identification and traceability. The original character detection method is artificial. However, for the same series of products with different material numbers or different batches that are very similar in appearance, manual visual inspection is prone to missing inspections and resulting in mixed materials. The original QR code detection method is manually scanned with a handheld scanner. The scanning efficiency of PCS products is 4-6s, and the efficiency is low. There are grade requirements for the ability to recognize and read QR codes. The scanning gun does not have this function for the time being. In addition, manual detection will inevitably lead to missing scans, which will cause defective products to flow out to the client and cause huge losses to customers. Complaints and fines. Therefore, for the identification and detection of characters and two-dimensional codes on flexible circuit boards, an automatic detection equipment that can ensure the accuracy, stability and high efficiency of the detection is needed to prevent manual missed detection of defective products. The outflow of materials to the client caused great complaints and fines from customers
