Description

Technical Field

[0001] This utility model relates to the field of automated equipment, specifically to an appearance inspection conveying and correction mechanism. Background Technology

[0002] In industrial automated production, product appearance inspection is often a key step in quality control and is widely used in fields such as electronics, automotive parts, and consumer devices. To improve efficiency, modern inspection systems generally adopt assembly line operations: after the product has completed the upstream process, it is transferred to the vision / optical inspection station by a robotic arm or gripping mechanism; after inspection, the gripping mechanism transfers the product to the downstream conveyor mechanism for packaging, sorting, or the next assembly process.

[0003] However, in existing technologies, the following technical problems generally exist in the transportation process after testing: The gripping mechanism is susceptible to mechanical errors, visual positioning deviations, or changes in product posture, making it difficult to guarantee the absolute repeatability of product placement each time. If the conveying mechanism lacks effective correction measures, products are prone to shifting, tilting, or even jamming during transport, leading to subsequent packaging, palletizing, or assembly failures.

[0004] Existing conveyor alignment mechanisms are mostly designed with a fixed height, and the position of the movable baffle is not adjustable. When the production line needs to switch to products of different sizes (especially those with large height differences), the entire set of fixtures or baffle assemblies must be replaced, resulting in low changeover efficiency and difficulty in meeting the needs of flexible production. For products with a high center of gravity, the fixed-height jacking point is prone to causing the product to tip over, posing safety hazards and quality risks.

[0005] Some simple alignment devices lack guiding structures, and the movable baffle is prone to shaking or jamming during the pushing process. After long-term use, they wear out severely, resulting in a decrease in alignment accuracy and an increase in maintenance costs, making it difficult to meet the requirements of continuous and high-cycle production. Utility Model Content

[0006] The main purpose of this utility model is to provide an appearance inspection conveying and correction mechanism to solve the problems in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: including fixed baffles installed on both sides of the conveying mechanism, and a movable baffle provided on one side of the front end of the conveying mechanism for pressing the product against the fixed baffles; A floating plate with lifting mechanism is provided on one side of the conveying mechanism. The middle part of the movable baffle is connected to the floating plate through a pushing mechanism. The cylinder of the pushing mechanism is fixed on the movable baffle, and the end of the pushing rod is fixed on the floating plate. The movable baffle is moved by the pushing mechanism to push the product against the fixed baffle.

[0008] Preferably, both the fixed baffle and the movable baffle are provided with multiple rollers on their inner sides, and the rollers roll against the product.

[0009] Preferably, fixed seats are provided on both sides below the floating plate, the fixed seats are fixed on the conveying mechanism, a second guide shaft is provided between the floating plate and the fixed seats, the bottom of the second guide shaft is fixed on the fixed seats, a second guide sleeve is sleeved on the second guide shaft, and the bottom of the second guide sleeve is fixed on the floating plate.

[0010] Preferably, a drive seat is provided at the lower center of the floating plate, the drive seat is fixed on the conveying mechanism, and a screw jack is provided on the drive seat. The end of the screw in the screw jack is connected to the floating plate and is used to drive the floating plate to move up and down.

[0011] Preferably, the screw jack is equipped with a worm gear and a worm that mesh with each other. The worm gear is equipped with a screw that is coaxially threaded. The top of the screw is fixed to a floating plate, and a handwheel is fixed to the end of the worm. By driving the handwheel to rotate, the worm gear and worm can be driven to rotate, which in turn drives the lead screw to move up and down.

[0012] Preferably, a first guide sleeve and a first guide shaft are provided between the two sides of the movable baffle and the floating plate. One end of the first guide shaft is fixed to the movable baffle, and the other end slides inside the first guide sleeve. The bottom of the first guide sleeve is fixed to the floating plate.

[0013] Preferably, the pushing mechanism is a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0014] This utility model provides an appearance inspection conveying and alignment mechanism, which has the following advantages: 1. After the product is placed onto the conveying mechanism by the gripping mechanism, the movable baffle is moved laterally by the pushing mechanism to accurately abut against the fixed baffle, eliminating the positional deviation caused by gripping and placing, and ensuring that all products are in a uniform reference position at the beginning of the transfer, providing a highly repeatable input state for downstream processes.

[0015] 2. The movable baffle is linked to the screw jack via a floating plate, allowing for adjustment of its vertical height. The jacking point can be flexibly set for products with different heights or center-of-gravity distributions. This is especially suitable for products with a high center of gravity or large size, effectively preventing the risk of overturning due to improper force during jacking or conveying.

[0016] 3. Both the fixed baffle and the movable baffle are equipped with rollers on their inner sides, which allow the product to move smoothly with the conveyor belt while clamping and limiting it, significantly reducing frictional resistance and the risk of surface scratches, and achieving a synergistic effect of flexible limiting and damage-free conveying.

[0017] 4. As the final connecting unit of the appearance inspection process, this mechanism ensures that the inspected and qualified products do not shift, collide or change their posture during transportation, avoiding the quality risks of qualified products being damaged during transportation, and truly achieving full process control from inspection to delivery.

[0019] like Figures 1-3 As shown, the appearance inspection conveying and alignment mechanism includes fixed baffles 2 installed on both sides of the conveying mechanism 1, and a movable baffle 3 is provided on one side of the front end of the conveying mechanism 1 for pressing the product 4 against the fixed baffles 2. A floating plate 6 is provided on one side of the conveying mechanism 1. The middle part of the movable baffle 3 is connected to the floating plate 6 through the pushing mechanism 12. The cylinder of the pushing mechanism 12 is fixed on the movable baffle 3, and the end of the pushing rod is fixed on the floating plate 6. The movable baffle 3 is moved by the pushing mechanism 12 to push the product 4 against the fixed baffle 2.

[0020] After the appearance inspection is completed on the production line, the product is transferred to the conveyor 1 by the gripping mechanism. In order to ensure the alignment of the product on the conveyor 1, the movable baffle 3 is driven by the push mechanism 12 to press the product against the fixed baffle 2. The fixed baffle 2 at the rear end can limit the movement of the product and ensure its movement trajectory.

[0021] like Figure 1As shown, both the fixed baffle 2 and the movable baffle 3 have multiple rollers on their inner sides, which roll against the product 4. Multiple fixed baffles 2 are installed on both sides of the top of the conveying mechanism 1, and a movable baffle 3 is located on one side of the front end of the conveying mechanism 1. The movable baffle 3's distance from the fixed baffle 2 is adjusted by a pushing mechanism 12. When the gripping mechanism places the product 4 onto the conveying mechanism 1, the movable baffle 3 unfolds with the fixed baffle 2 to facilitate the placement of the product 4. After placement, the pushing mechanism 12 drives the movable baffle 3 to move, pushing the product 4 against the fixed baffle 2 for clamping, thus restricting the movement trajectory of the product 4. The rollers on the inner sides of the fixed baffle 2 and the movable baffle 3 ensure smooth movement of the product 4 by the conveying mechanism 1.

[0022] like Figures 1-2 As shown, fixed seats 5 are provided on both sides below the floating plate 6. The fixed seats 5 are fixed to the conveying mechanism 1. A second guide shaft 11 is provided between the floating plate 6 and the fixed seats 5. The bottom of the second guide shaft 11 is fixed to the fixed seats 5. A second guide sleeve 10 is sleeved on the second guide shaft 11. The bottom of the second guide sleeve 10 is fixed to the floating plate 6. The two sides of the floating plate 6 slide on the second guide shaft 11 on the fixed seats 5 through the second guide sleeve 10, ensuring smooth up and down sliding. The height of the movable baffle 3 can be adjusted to accommodate the pushing of products 4 of different sizes. For large products 4, the height of the movable baffle 3 can be appropriately increased to prevent the product 4 from tipping over due to instability when pushing it.

[0023] like Figure 2 As shown, a drive seat 9 is provided in the middle of the lower part of the floating plate 6. The drive seat 9 is fixed on the conveying mechanism 1. A screw jack 13 is provided on the drive seat 9. The end of the screw in the screw jack 13 is connected to the floating plate 6 and is used to drive the floating plate 6 to move up and down.

[0024] The screw jack 13 is equipped with a worm gear and a worm that mesh with each other. The worm gear is equipped with a screw 14 that is coaxially threaded. The top of the screw 14 is fixed on the floating plate 6, and a handwheel 15 is fixed at the end of the worm. By rotating the drive handwheel 15, the worm gear and worm can be rotated, which in turn drives the lead screw 14 to move up and down.

[0025] The floating plate 6 is driven up and down by the screw jack 13, which in turn drives the movable baffle 3 to rise and fall to accommodate products 4 of different heights.

[0026] Preferably, a first guide sleeve 7 and a first guide shaft 8 are provided between both sides of the movable baffle 3 and the floating plate 6. One end of the first guide shaft 8 is fixed to the movable baffle 3, and the other end slides inside the first guide sleeve 7. The bottom of the first guide sleeve 7 is fixed to the floating plate 6. The two sides of the movable baffle 3 slide against the first guide sleeve 7 on the floating plate 6 through the first guide shaft 8, so that the movable baffle 3 can be driven to move more smoothly by the pushing mechanism 12.

[0027] Preferably, the jacking mechanism 12 is a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. The appropriate type can be selected based on the working conditions, making it suitable for a wide range of applications.
