Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inkjet detection. More particularly, the present application relates to an inkjet detection structure and an inkjet device. BACKGROUND

[0002] In the field of inkjet printing, it is usually necessary to spray ink onto a product to be inked (such as a wafer) by a nozzle to implement an inkjet printing job.

[0003] In an inkjet printing job, a predetermined spraying amount is usually set for the nozzle, and then the nozzle is controlled to spray according to the predetermined spraying amount. However, a problem arises in that the actual amount of ink sprayed by the nozzle is not always consistent with the predetermined spraying amount, and sometimes deviates, thereby affecting the effect of the inkjet job.

[0004] If the deviation is to be corrected, the actual spraying amount of the nozzle needs to be detected for comparison with the predetermined spraying amount, and then error correction processing is performed.

[0005] However, in the process of detecting the actual spraying amount of the nozzle, the nozzle may be blocked or not smooth when spraying ink, which leads to the phenomenon that the actual ink spraying amount cannot be accurately detected, increasing the difficulty of detection work. At present, there is no effective solution to this problem, and it is therefore an urgent problem to be solved. SUMMARY

[0006] An object of embodiments of the present application is to solve the above problems and provide the advantages to be described later.

[0007] Another object of embodiments of the present application is to provide an inkjet detection structure and an inkjet device that can be used to detect the actual ink spraying amount of a nozzle and improve the detection accuracy of the actual ink spraying amount.

[0012] The inkjet detection structure of embodiments of the present application is provided with a detection panel having an inkjet detection area and a test spraying area, so that the nozzle can be sprayed towards the test spraying area first, and then sprayed towards the weighing tray in the inkjet detection area after the ink flows smoothly. Thus, the actual ink sprayed by the nozzle can be obtained, and the accurate actual spraying amount can be detected by the weighing scale.

[0013] It can be understood that after the actual injection amount is obtained, the deviation weight between the actual injection amount and the old predetermined injection amount can be obtained, and then the deviation can be corrected and the predetermined injection amount of the nozzle can be corrected to be consistent with the actual injection amount, so that the actual ink injection of the nozzle can be accurately controlled.

[0014] In some embodiments, the ink injection detection structure further comprises an operation table, and the detection panel is installed on the operation table.

When weighing is needed, the cover is opened for detection, and when weighing is not needed, the cover is closed to protect the tray, so that the tray is not damaged by external force or contaminated by dust, etc.

[0032] In some embodiments, the movable connection is to the detection area or the detachable connection is to the detection area.

[0057] Since the inkjet head may be blocked or not fluent when spraying ink, it is difficult to detect the actual inkjet amount. Therefore, before spraying ink in the inkjet detection area 101, the inkjet head sprays ink in the test spraying area 102, and then the inkjet detection is performed in the inkjet detection area 101 after no adverse phenomenon, which is beneficial to the implementation of the detection operation. Specifically, the inkjet detection structure 10 of the embodiments of the present application is provided with the detection panel 100 having the inkjet detection area 101 and the test spraying area 102, so that the inkjet head can be sprayed towards the test spraying area 102 first, and then the ink is sprayed towards the weighing tray 110 in the inkjet detection area 101 after the ink is fluent, so that the actual ink sprayed by the inkjet head can be obtained, and the accurate actual spraying amount can be detected by the weighing scale 120.
