[0002] With the development of technology and the improvement of automated production levels, visual inspection technology has been widely adopted to replace traditional manual inspection methods in the manufacturing process of electronic products such as computer keyboards. Visual inspection can significantly improve inspection efficiency and consistency, but due to the complexity and diversity of product appearance defects, existing visual inspection systems still have certain limitations, leading to some products being misjudged as unqualified.

[0003] In related technologies, to prevent defective products from reaching the customer, testing standards are usually raised. However, this may lead to some actually qualified products being mistakenly judged as defective (i.e., "over-crippling"), thus affecting process yield, causing material waste and increasing production costs. In addition, the current re-judgment of defective products mainly relies on manual re-inspection. However, due to the lack of effective means of presenting re-judgment information, manual re-judgment is inefficient and easily affected by human factors, resulting in unstable re-judgment results.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0034] Optionally, as shown in Figure 6 Display unit 11 is set on the top of rack 4, so that rejudgment personnel can clearly view rejudgment information, improve rejudgment efficiency.Both sides of rack 4 are provided with rejudgment workstation, so that multiple rejudgment personnel can operate simultaneously, improve the overall processing capacity of rejudgment device.

[0035] Optionally, rejudgment mechanism 1 further includes light source 12 set on the side of identification unit 13, for providing illumination and enhancing product identification effect.In rejudgment process, light source 12 can adjust illumination intensity and angle according to product material, surface characteristics and bar code identification requirement, to optimize the scanning effect of bar code identification unit 13, ensure that product information can be accurately collected under different environmental illumination conditions.In addition, light source 12 can also assist artificial rejudgment, by enhancing the visibility of unqualified product surface, so that operator can more clearly observe defect site, improve the accuracy and efficiency of rejudgment.

[0036] As shown in Figures 2-3As shown, in this embodiment, the conveying mechanism 2 includes a conveying line body 21 and a blocking strip 22, which are used to convey the products confirmed qualified after re-trial to the subsequent process, ensure the stability of the products during conveying, and convey unqualified products to the material collecting mechanism 3. The conveying line body 21 is arranged at one end of the re-trial mechanism 1 and is used to carry and convey the qualified products. The conveying line body 21 can adopt the forms of belt conveying, roller conveying, chain conveying, etc. to meet the conveying needs of different products. The blocking strips 22 are arranged on both sides of the conveying line body 21 respectively and jointly form a limiting area, which is used to prevent the qualified products from deviating or toppling during conveying. Alternatively, the blocking strips 22 can adopt fixed structures or adjustable structures to adapt to different specifications of products and ensure the stable movement of the products along the set conveying direction, thereby effectively preventing the deviation of the qualified products, improving the conveying stability, and ensuring the smooth entry of the products into the next process.

[0037] Preferably, the conveying mechanism 2 further includes a blocking mechanism 23 arranged in the conveying line body 21, one end of which is movably extended out of the conveying line body 21 and can be extended or retracted as needed during conveying of the qualified products. The blocking mechanism 23 can adopt the forms of air cylinder driving, mechanical pop-up structure, or electric push rod, etc. In actual work process, when there are multiple qualified products continuously conveyed on the conveying line, the blocking mechanism 23 can be periodically extended to temporarily block the advancement of the subsequent products, so that the front products have enough time to enter the next process or be classified, thereby avoiding product accumulation and mutual collision, ensuring the smoothness and safety of the conveying process. When the unqualified products are conveyed to the material collecting mechanism 3, the blocking mechanism 23 is extended to block them, facilitating the material collecting of the material collecting mechanism 23.

[0038] Specifically, the blocking mechanism 23 includes a blocking air cylinder 24 and a blocking piece 25. The blocking air cylinder 24 is arranged in the conveying line body 21, and the blocking piece 25 is installed at one end of the blocking air cylinder 24 and can be pushed out in a direction perpendicular to the conveying line body 21, thereby effectively blocking the qualified products on the conveying line body 21. When it is needed to temporarily separate the products, the blocking air cylinder 24 pushes the blocking piece 25 to extend upward to block the advancement of the subsequent products. After the front products enter the next process smoothly, the blocking air cylinder 24 retracts the blocking piece 25 to continue conveying the products.

[0039] In order to further improve the accuracy of blocking, as shown in FIG. 4, the blocking mechanism 23 further includes a blocking sensor 26 arranged on the blocking air cylinder 24 and used to detect the position of the blocking piece 25. When the blocking piece 25 is in the extended position, the blocking sensor 26 sends a signal to the blocking air cylinder 24 to stop the extension of the blocking piece 25, thereby preventing the blocking piece 25 from being continuously extended and causing damage to the products. Figure 3As shown, in the embodiment, the blocking mechanism 23 further includes an inductor 26 arranged at one end of the blocking cylinder 24 and electrically connected with the blocking cylinder 24. When the qualified products move along the conveying line body 21 and enter the blocking area, the inductor 26 detects the presence of the qualified products and sends a control signal to the blocking cylinder 24, prompting the blocking cylinder 24 to drive the blocking piece 25 to pop out, thereby temporarily blocking the qualified products and preventing them from entering the next process too quickly or from colliding and piling up. After the front products are successfully transported away, the inductor 26 detects that the blocking area is empty, and then sends a signal to the blocking cylinder 24 to make it retract the blocking piece 25, so that the subsequent products can continue to be transported.

[0040] As shown, Figures 4-5 In the embodiment, the material collecting mechanism 3 includes a bin 31 arranged at one end of the rejudging mechanism 1, and supporting units 32 are arranged on both sides of the bin 31, which can provide support for the unqualified products entering the bin 31 to prevent the products from tilting or falling. The supporting units 32 can adopt a fixed structure or an adjustable structure to adapt to unqualified products of different sizes and improve storage stability. A jacking unit 33 is arranged below the bin 31 for jacking the unqualified products layer by layer into the bin 31 to realize stacked storage. The jacking unit 33 can adopt the form of an electric push rod, a cylinder or a lifting platform, so that the unqualified products are lifted in sequence, the space of the bin 31 is fully utilized, the material collecting efficiency is improved, and blockage caused by product piling up is avoided.

[0041] Specifically, the bin 31 includes two oppositely arranged bottom plates 34 and a plurality of baffles 35, and the plurality of baffles 35 are arranged at one end of the two bottom plates 34 opposite to each other and jointly form a storage area. The baffles 35 can limit the movement range of the unqualified products to prevent them from tilting or sliding during storage. Alternatively, the baffles 35 can adopt a fixed structure or be designed as an adjustable type to adapt to unqualified products of different specifications.

[0042] Specifically, the supporting unit 32 includes two supporting cylinders 38 arranged at one end of the two bottom plates 34 away from the baffles 35, and the two supporting cylinders 38 are drivingly connected with two supporting plates 39, and the supporting plates 39 can move synchronously with the extension and retraction action of the supporting cylinders 38. During work, when it is necessary to support the unqualified products in the storage area, the supporting cylinders 38 drive the supporting plates 39 to pop out to form a supporting structure with the baffles 35, so that the unqualified products are stably stored and prevented from tilting or falling.

[0043] Optionally, the silo 31 is provided with a control system, which is in communication connection with the jacking cylinder 36 and the material supporting cylinder 38, and is used for coordinating the automatic operation of the material collecting mechanism 3. In addition, the top of the baffle 35 is provided with a full material sensor for detecting the stacking height of the unqualified products in the storage area. The full material sensor is in electrical connection with the control system, and when the unqualified products are stacked to a certain height layer by layer, the full material sensor detects that the products have reached the set upper limit of storage, and sends a signal to the control system to trigger the corresponding processing action, for example: stopping the jacking cylinder 36 from continuing to lift and preventing the product from overflowing due to the stacking of the product being too high; controlling the material supporting cylinder 38 to lock the material supporting plate 39 to ensure the stability of the stacked products; triggering an alarm to remind the operator to empty the silo 31 in time.

[0044] Optionally, as shown in Figure 4 The safety grating 30 is provided around the silo 31, which is used for detecting whether a person or a foreign object enters the silo 31 area, so as to ensure the safety of the equipment operation. In the working process, when the safety grating 30 detects that a person approaches or a foreign object enters the silo 31 area, the safety grating 30 will immediately send a signal to the control system, and the control system will trigger the safety protection measures, for example: suspending the operation of the jacking cylinder 36 and the material supporting cylinder 38 to prevent safety accidents caused by misoperation; issuing an audible and light alarm to remind the operator to stay away from the dangerous area; locking the material collecting mechanism 3 of the rejudging device to ensure that the system operates in a safe state.

[0045] Optionally, the jacking unit 33 includes a jacking cylinder 36 arranged below the two bottom plates 34, the jacking cylinder 36 is in driving connection with a jacking plate 37, and the jacking plate 37 can be lifted up and down with the extension and retraction action of the jacking cylinder 36. In the working process, when the unqualified products enter the storage area, the jacking cylinder 36 drives the jacking plate 37 to move upwards, passes through the gap between the two bottom plates 34, and jacks up the unqualified products to contact with the material stripping plate. At this time, the material supporting cylinder 38 drives the material supporting plate 39 to move outward, so that the unqualified products in the storage area are stacked with the unqualified products. Then, in order to ensure the stability of the stacking, the material supporting cylinder 38 drives the material supporting plate 39 to move inward again, so as to provide support for the unqualified products jacked into the storage area and prevent the unqualified products from falling off.

[0046] The utility model also provides a keyboard production equipment, including rejudging device of above embodiment.
