[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 2 The device comprises the following key components: a material conveying assembly, primarily responsible for stably conveying products along a preset direction (set according to actual production needs); and a detection assembly 110, which integrates a detection fixture 111, an optical module 112, and a robotic arm 113. The detection fixture 111, located on one side of the optical module 112, securely holds the product to be detected and accurately moves it to the detection area slot 121 in the detection area of ​​the frame 120. The optical module 112 utilizes traditional image processing technology to accurately capture and analyze image information of the product, thereby conducting a comprehensive and detailed evaluation of product quality. The robotic arm 113, located on the other side of the detection fixture 111, can return qualified products to the material conveying assembly to continue the production process. The frame 120 not only stably supports the detection assembly 110 but also features a sliding and fixed connection mechanism with the material conveying assembly, thereby enhancing the device's stability and significantly improving its flexibility and adaptability.

[0029] In some embodiments, the inspection fixture 111 can smoothly accommodate and handle products with a maximum size not exceeding 400 mm. However, it should be noted that this invention is not limited to the specific product size range that the inspection fixture 111 can accommodate. The key is that the inspection fixture 111 can effectively load the product and move it accurately to the designated slot in the inspection area to complete the subsequent inspection process.

[0030] In some embodiments, the rack 120 not only provides a stable supporting foundation but also integrates a button device 122. This design allows users to seamlessly switch between automatic and manual detection modes, greatly improving operational flexibility. Specifically, the button device 122, as part of a PLC (Programmable Logic Controller), can control the operating logic of the entire device, including but not limited to the switching function between automatic and manual detection modes. This design ensures efficient operation and flexible handling of the device, meeting the needs of diverse detection scenarios.

[0031] In some embodiments, the rack 120 is also equipped with a sensor assembly that is highly sensitive. During the operation of the device, once it detects that a product has arrived at the detection area 121, it can immediately send a start signal to the optical module 112, thereby quickly triggering the entire detection process and ensuring the efficiency and accuracy of the detection work.

[0032] Preferably, the width of the frame 120 of this device can be set to 750 mm, which effectively saves production space.

[0033] In some embodiments, such as Figure 1As shown, the material conveying assembly consists of a main conveyor line 130, the bottom of which is fixedly connected to the support frame 140 to ensure structural stability. On both sides of the frame, support plates 150, at the same height as the main conveyor line 130, are symmetrically installed. The support plates 150 are equipped with a first connecting slide rail 151, and the frame 120 is equipped with a second connecting slide rail 123 that matches the first connecting slide rail 151. This allows the material conveying assembly to be stably and flexibly connected and fixed to the frame 120, achieving high efficiency in product inspection.

[0034] In some embodiments, a fixed bracket 160 is fixedly connected to the top of the main conveyor 130. This bracket can be equipped with light strips to provide ample lighting for the operating area, and a shelf 170 is provided inside the bracket. This design allows workers to conveniently place or pre-process products temporarily, such as placing a computer on it to view product testing results immediately, thereby improving work efficiency and ease of operation.

[0035] In some embodiments, such as Figure 2 As shown, the inspection fixture 111 integrates a slide rail assembly 210 and a transfer stage 220. The transfer stage 220 is slidably connected to the slide rail assembly 210, ensuring smooth product movement along the slide rail. To further enhance the stability of the product during movement, a baffle 230 is provided between the slide rail and the transfer stage 220. In the actual workflow, the operator can place the product on the transfer stage 220, and then use the guiding function of the slide rail assembly 210 to accurately transport the product to the inspection area slot 121, so that the optical module 112 can perform comprehensive and detailed quality inspection of the product.

[0036] In some embodiments, a spacer 240 is provided between the detection area slot 121 and the baffle 230 of the detection fixture 111 to ensure accurate positioning of the product during the detection process.

[0037] In some embodiments, the device also includes a feeding area, which can be used to properly store products that have been determined to be defective after rigorous testing. It is worth noting that the feeding area can be designed with a buffer function, capable of accommodating multiple sets (e.g., four sets) of defective products simultaneously. This design aims to minimize disruption to the overall production rhythm and ensure the smooth and efficient operation of the production line. During the inspection process, once a defective product is detected, the operator can choose to manually remove it or safely and quickly transfer it to the designated feeding area via a conveyor for subsequent processing and analysis.

[0038] In some embodiments, the support plate 150 can serve as a feeding area, ensuring an extremely short operating distance thanks to its sliding connection with the frame 120. When product inspection results show that the product is unqualified, these products can be quickly and easily transferred to the support plate 150, thereby improving the processing efficiency of the production line.

[0039] The specific steps of the device's workflow are as follows: First, the product to be inspected is extracted from the main conveyor line 130 and placed on the moving platform of the inspection fixture 111 in the inspection component 110. Then, the slide rail assembly 210 built into the fixture smoothly transfers the product to the preset inspection area slot 121. Once the sensor assembly detects that the product has arrived at the inspection area slot 121, it immediately sends a start command to the optical module 112, triggering it to automatically execute the inspection task. In the inspection stage, on the one hand, this device can automatically trigger the automated inspection process using sensors, eliminating the need for manual operation and significantly improving inspection efficiency. On the other hand, this device also retains a convenient button for manually starting the inspection, and can easily switch between manual and automatic inspection modes via a PLC (Programmable Logic Controller) to flexibly adapt to diverse production needs. For products that pass inspection, the robotic arm 113 can respond quickly, accurately grip, and safely return them to the main conveyor line 130 to ensure the smooth operation of subsequent production processes. For products that fail inspection, operators can choose to manually remove them or use a conveyor device to transfer them to the designated unloading area. To improve production efficiency, the unloading area is specially designed with a buffer function, capable of accommodating multiple sets of defective products and effectively preventing disruption to the overall production rhythm. Simultaneously, to ensure the continuity and efficiency of the production process, the unloading area can be cleaned periodically. Particularly noteworthy is that the cycle time of this device (excluding product placement time) is only 7 seconds, indicating that the device can efficiently complete a testing task in a very short time, thereby significantly improving the overall efficiency of the production line.
