Description

Technical Field

[0001] The present invention belongs to the technical field of V-bending powdering test for zinc-iron alloy plates, and specifically relates to a fully automatic V-bending powdering test system and method for zinc-iron alloy plates. Background Art

[0002] The surface of the zinc-iron alloy steel plate is plated with an anti-corrosion coating. The factory inspection of the product needs to detect the adhesion performance of the zinc-iron alloy coating, and usually the V-bending powdering test is used for evaluation.

[0003] Currently, the V-bending powdering test is carried out manually. The entire V-bending powdering test process includes: (1) Cleaning the surface of the specimen: Manually wipe the upper and lower surfaces of the specimen with alcohol to remove oil stains; at the same time, wipe the upper and lower dies. (2) Natural drying: The specimen template after wiping alcohol needs to be naturally dried and can only be put into the V-bending test machine for the V-bending test after drying. (3) V-shaped bending: Select dies with different angles according to the requirements of GB / T 39130-2020 "Test Method for Adhesion of Zinc Coating on Zinc-Iron Alloy Products", and manually use the V-bending test machine to bend the upper and lower surfaces of the specimen into a "V" shape. (4) Flattening: Manually use the flattening die to press the specimen after V-shaped bending into 180° horizontal. The existing production method of the V-bending powdering test has the following problems.

[0004] 1. Low production efficiency. The V-bending powdering test link of the zinc-iron alloy plate has always been the bottleneck of the production efficiency in the finished product physical inspection operation area. The specific reasons are as follows: In the V-bending powdering test, it is necessary to manually wipe the die and the specimen with alcohol cotton; select a suitable bending die according to the test standard, manually punch to bend the steel plate, then manually turn it over, punch again, and finally use the flattening die to flatten it. The test process is cumbersome and the labor efficiency of personnel is low. It is difficult for the V-bending powdering test cycle compliance rate to meet the production requirements.

[0005] 2. High labor intensity. Using traditional manual V-bending powdering test equipment requires manual completion of cumbersome processes such as sorting specimens, wiping specimens, natural drying, bending specimens, flattening specimens, and finally sorting and placing. Such repetitive actions are performed throughout the work shift, and the labor intensity of employees is too high.

[0006] 3. There are potential hazards in occupational health, environmental protection and safety. During the specimen wiping process, high-purity anhydrous alcohol is used, and anhydrous alcohol has high volatility, posing a risk of respiratory irritation caused by inhalation into the nasal cavity by personnel.

[0039] (2) Ultrasonic cleaning: The loading and unloading robot automatically grabs the tray and transfers it to the automatic lifting frame in the cleaning tank of the ultrasonic cleaning device; the automatic lifting frame automatically descends, and ultrasonic cleaning is automatically started. After cleaning, the automatic lifting frame rises and waits for the tray and the specimen to dry. (3) Centering and positioning: The loading and unloading robot transfers the dried tray to the centering workbench of the centering and positioning device and positions and clamps the material table. (4) V-bending test: The loading and unloading robot clamps a specimen to be tested on the tray on the centering workbench, moves it to the barcode scanner, obtains the V-bending angle required for this test by scanning the identification code, and then the loading and unloading robot transfers the specimen to the V-bending die with the corresponding angle on the full-automatic V-bending testing machine for a V-bending stamping. After completion, the loading and unloading robot samples and flips the V-bent specimen, and then sends it to the V-bending die for a second V-bending stamping. After completion, the loading and unloading robot samples the specimen to the flattening fixture for flattening; finally, the loading and unloading robot places the flattened specimen into the sample tray on the centering and positioning device; then grabs the next specimen to be tested and repeats the V-bending test until all the specimens on the tray on the centering workbench are completed. (5) Returning the tray and unloading: The loading and unloading robot transfers the entire tray to the material table. The V-bending test process for one tray of specimens is completed.

[0040] Preferably, in actual tests, multiple trays can be prepared for testing simultaneously. For example, four sets of trays can be prepared on the tray table. During the test process, when the first tray is dried and transferred to the centering and positioning device, the loading and unloading robot will grab the second tray and transfer it to the full-automatic ultrasonic cleaning device for cleaning; when there is an empty position in the centering and positioning device and there is a dried tray on the full-automatic ultrasonic cleaning device, the loading and unloading robot will transfer the dried tray to the centering and positioning device. In this way, the waiting time during the cleaning process can be reduced, and the production efficiency can be improved. After all 4 trays are completed, the test ends.
