Efficiently promoting ESG sustainability goals, ePaper is characterized by energy saving, low carbon footprint, health benefits, and no light pollution. However, there are currently no dedicated optical measurement machines for ePaper on the market. Therefore, providing a dedicated optical measurement machine for ePaper would be of paramount importance.

Each circuit board (as attached) Figure 2 There are two FFC connectors, but only one electronic paper can be processed manually at a time (as shown in the attached image). Figure 1 Therefore, each circuit board needs to be processed twice, resulting in a longer processing time.

[0005] (2) When personnel switch between products with large differences in size and model, they need to be trained. This is not easy for companies with high staff turnover, and frequent changes can also waste time and costs, thus significantly improving production efficiency.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0036] This utility model is mainly applied to the electronic paper image inspection process, belonging to the automatic image inspection equipment, specifically the dynamic optical measurement machine. It consists of a protective main unit 1, an automatic electronic paper insertion / removal optical inspection mechanism 2, and an automatic feeding and packing mechanism 3, as shown in the attached diagram. Figure 4 As shown.

[0037] As attached Figure 5 and attached Figure 6As shown, the electronic paper automatic insertion and removal optical inspection mechanism consists of the following components: A fixed operating platform 201 serves as the base for the mechanism, providing connection and support for the entire structure. An electronic paper receiving angle displacement compensation stage 202 effectively fixes the electronic paper and compensates for angle and displacement before insertion, achieving an insertion offset accuracy of ±0.003mm. Regarding the electronic paper feeding alignment camera 203, since the electronic paper is initially placed sequentially within the cassette of the automatic feeding and packing mechanism and gripped by the built-in transfer clamping mechanism of the protective host for feeding, it needs to be placed in front of the electronic paper receiving angle displacement compensation stage. An image alignment is performed, and the image system captures the electronic paper displacement difference data and uploads it to the host for data compensation. Regarding the circuit board alignment imaging system 204, a vision system is used to compensate for angular displacement deviations of the circuit board. It works in conjunction with the Z-axis lifting and transfer module and the XY-axis transfer module to effectively displace and provide highly stable clamping according to the different sizes of each circuit board. It also works with the electronic paper receiving angular displacement compensation stage to complete the effective insertion action. Both the electronic paper feeding alignment camera 203 and the circuit board alignment imaging system 204 can be industrial cameras. Regarding the Z-axis lifting and transfer module 205, it imports the deviation data from the images captured by the circuit board alignment imaging system and works in conjunction with the XY-axis transfer module to stably move the circuit board to the marked position. Regarding the XY-axis transfer module 206, it imports the deviation data from the images captured by the circuit board alignment imaging system and works in conjunction with the Z-axis lifting and transfer module to stably move the circuit board to the marked position.

[0038] As attached Figure 7 As shown, the automatic feeding and packing mechanism consists of the following components: Regarding the E-paper tray clamping and positioning mechanism 301, since the E-paper tray (hereinafter referred to as the tray) is made of PP or PVC injection molding and demolding material, its shape is easily affected by temperature changes, causing deviations in product position accuracy. Therefore, a tray clamping and positioning mechanism is needed to fix the tray, facilitating product positioning calibration during future production. This mechanism works in conjunction with the built-in transfer clamping mechanism of the protective host to grip and perform the feeding process. Holes are drilled in the supports of the main steel frame 302 of the automatic feeding and packing mechanism to fix various mechanisms and provide high-precision displacement switching. Regarding the dual X-axis belt conveyor 303 for feeding and discharging, personnel place the tray onto the right X-axis belt conveyor, which is then moved inside the camera platform to the Z-axis lifting and transfer module two, and then upwards to the Y-axis switching slide of the rodless cylinder, where the tray is fixed in conjunction with the E-paper tray clamping and positioning mechanism. Regarding the rodless cylinder Y-axis switching slide 304, the material tray that has been picked up is moved to the left and retracted to the left side of the left-side Z-axis lifting and transfer module 2, which then moves it downwards to the left side of the infeed and discharge dual X-axis belt conveyor. Regarding the Z-axis lifting and transfer module 2 305, it is fixed to the main steel frame of the automatic feeding and packing mechanism and works with the infeed and discharge dual X-axis belt conveyor to move and lift the material tray.

[0039] As attached Figure 8 As shown, the E-paper tray clamping and positioning mechanism consists of the following components: The top surface of the clamping and positioning mechanism platform 311 is used to fix the X-axis bidirectional positioning cylinder group and the Y-axis bidirectional positioning cylinder group. A hollowed-out section in the middle of the platform avoids the material feeding and discharging dual X-axis belt conveyor. Linear sliders are fixed on both sides of the long side, and these linear sliders are connected to the main steel frame of the automatic feeding and packing mechanism. A rodless cylinder on the Y-axis switching slide provides forward power, stably pushing the tray. The X-axis bidirectional positioning cylinder group 312 uses a slide cylinder according to the tray length, combined with the Y-axis double-sided bidirectional positioning cylinder group for clamping action, aiming to stabilize the tray. The Y-axis double-sided bidirectional positioning cylinder group 313 uses a slide cylinder according to the tray width, combined with the Y-axis bidirectional positioning cylinder group for clamping action, aiming to stabilize the tray.

[0040] The operation of this utility model can be carried out using the following steps: The corresponding product is placed on the automatic feeding and packing mechanism 3 and fed into the testing station by the feeding and discharging dual X-axis belt conveyor 303. The product is then gripped by the built-in transfer and clamping mechanism of the protective host 1 for the feeding process, and placed in front of the electronic paper receiving angle displacement compensation platform 202. The attached... Figure 3 The optical measuring instrument shown performs a comprehensive inspection of the electronic paper; based on the original set dimensions and error values ​​of the product, the inspection data is compared, and unqualified products are picked out after comparison. The original inspection data is retained, and the batch number and product serial number of the unqualified products are recorded; after recording, the electronic paper products are removed from the inspection position; qualified products are picked up by the built-in transfer clamping mechanism of the protective host 1 and returned to the box and exited to the infeed and outfeed dual X-axis belt conveyor 303; finally, the personnel take away the material tray that has completed the inspection.
