Description

Technical Field

[0001] This utility model relates to the field of automatic detection, and specifically to a flipping mechanism for appearance inspection. Background Technology

[0002] In the field of automated production and quality inspection, products with high appearance requirements typically require comprehensive appearance defect inspection. Since scratches, stains, dents, and other defects may exist on both sides of the product, the product needs to be flipped over during the inspection process so that the inspection equipment can completely scan its entire surface.

[0003] Currently, common product flipping methods mainly include manual flipping and mechanical single-station flipping mechanisms. Manual flipping relies on operators to complete the task manually, which is not only inefficient and labor-intensive, but also prone to product damage or missed inspections due to improper operation, making it difficult to meet the high-efficiency and consistent inspection requirements of modern production lines. Existing mechanical flipping devices mostly use a single clamping and flipping unit to operate one product at a time, processing only one product at a time. When facing multi-station continuous conveyor production lines, the flipping cycle time becomes a bottleneck for the overall line efficiency, seriously affecting inspection efficiency.

[0004] Furthermore, existing flipping mechanisms generally suffer from insufficient clamping force or a single clamping method. Most flipping devices lack a precise coordination control mechanism with the production line, failing to achieve accurate synchronization between product placement and clamping actions, resulting in positioning deviations.

Detailed Implementation

[0022] like Figures 1-4 As shown, the flipping mechanism for appearance inspection includes a vertical moving mechanism mounted on a horizontal moving mechanism. The vertical moving mechanism is provided with multiple clamping and flipping mechanisms 7, which are located at the same horizontal position to synchronously drive multiple products to flip. The flipping plate 701 in the clamping and flipping mechanism 7 is fixed with rails 702 on both sides, and two sliding plates 703 are provided between the two rails 702. A clamping plate 705 is fixed in the middle of the sliding plate 703 for clamping the product. Limiting blocks 706 are fixed on both sides of the sliding plate 703 for locking on the four corners of the product. A bidirectional slide cylinder 704 is fixed on the flip plate 701. The bidirectional slide cylinder 704 is used to drive the two slide plates 703 to move relative to each other. A swing cylinder 709 is also provided at the tail of the flip plate 701. The swing cylinder 709 is used to drive the flip plate 701 to rotate. The swing cylinder 709 is mounted on the vertical moving mechanism.

[0023] Since the appearance inspection is a streamlined process, the flipping mechanism is located on one side of the conveyor belt. Based on the spacing of the multiple clamping and flipping mechanisms 7, corresponding positioning detection is installed on the conveyor belt to ensure that multiple products are precisely positioned within the clamping area of ​​each clamping and flipping mechanism 7. The horizontal and vertical moving mechanisms bring the clamping and flipping mechanisms 7 closer to the product, positioning the product between two clamping plates 705. A bidirectional sliding cylinder 704 then controls the two clamping plates 705 to hold the product. Simultaneously, the four corners of the product are secured by limit blocks 706 to prevent the product from falling due to insufficient clamping force during the flipping process. After the product is clamped, the horizontal and vertical moving mechanisms move the product away from the conveyor belt. Then, a swing cylinder 709 drives the product to flip 180° before placing it back onto the conveyor belt, enabling comprehensive appearance scanning and inspection of the product.

[0024] Preferably, the horizontal moving mechanism includes a base plate 3, a horizontal track 2, and a horizontal moving platform 1, with the two ends of the base plate 3 moving against the horizontal track 2 and the horizontal moving platform 1 respectively; The vertical mounting base 8 and the vertical rail 5 in the vertical moving mechanism are installed on both sides of the base plate 3.

[0025] The horizontal moving platform 1 is a lead screw driven structure. The two ends of the lead screw are supported by bearings and rotate inside the horizontal moving platform 1. One end of the lead screw is connected to a servo motor. The bottom of one end of the base plate 3 is connected to the lead screw through a lead sleeve. The lead screw is driven to rotate by the servo motor, thereby driving the lead sleeve and the base plate 3 to move back and forth. The other end of the base plate 3 is connected to the horizontal track 2 via multiple sliders.

[0026] The horizontal moving platform 1 drives the base plate 3 to move back and forth against the horizontal track 2, while simultaneously driving the vertical moving mechanism and the clamping and flipping mechanism 7 to move back and forth, thereby approaching the product on the conveying mechanism.

[0027] Preferably, a vertical moving platform 6 is mounted on the vertical mounting base 8, and a vertically moving mounting plate 4 is provided between the vertical moving platform 6 and the vertical track 5. Multiple clamping and flipping mechanisms 7 are mounted on the mounting plate 4.

[0028] The vertical moving platform 6 is a lead screw driven structure. The two ends of the lead screw are supported by bearings and rotate inside the vertical moving platform 6. One end of the lead screw is connected to a servo motor. The bottom of one end of the mounting plate 4 is connected to the lead screw through a screw sleeve. The servo motor drives the lead screw to rotate, thereby driving the screw sleeve and the mounting plate 4 to move up and down. The other end of the mounting plate 4 is connected to the vertical rail 5 via multiple sliders.

[0029] The vertical moving platform 6 drives the mounting plate 4 to move up and down against the vertical track 5, while simultaneously moving the clamping and flipping mechanism 7 to approach the product on the conveying mechanism.

[0030] Preferably, a tank chain is installed between the base plate 3 and the ground for cable protection and traction. A tank chain is also installed between the vertical mounting base 8 and the mounting plate 4 for cable protection and traction. The mounting plate 4 also has cable grooves for cable organization and fixing. This facilitates the fixing of cables and conduits, and the cables move with the moving mechanism, thus providing protective traction for the cables.

[0031] Preferably, the swing cylinder 709 is mounted on the mounting plate 4 in the horizontal moving platform 1. Position sensors 708 are provided on the upper and lower sides of the mounting plate 4 at the positions corresponding to the clamping and flipping mechanism 7. A detection component 707 is provided on the flipping plate 701, and the detection component 707 is located inside the position sensor 708.

[0032] The swing cylinder 709 drives the flip plate 701 to flip, which in turn drives the detection component 707 to rotate. When the detection component 707 enters the position sensor 708, it is flipped into place. The two position sensors 708 are set at 0° and 180° respectively.

[0033] Preferably, the slide plate 703 has multiple mounting holes for adjusting the clamping of the clamping plate 705 and the limiting block 706 for products of different sizes. By adjusting the clamping plate 705 and the limiting block 706 with different spacing, it can accommodate products of different sizes, thus broadening its applicability.

[0034] Preferably, the side of the clamping plate 705 and the limiting block 706 that contacts the product is provided with a flexible pad. The flexible pad directly contacts the product, avoiding damage to the product due to clamping.

[0035] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
