Description

Technical Field

[0001] The present invention relates to the field of inkjet detection technology, and more specifically, to an inkjet detection structure and an inkjet device. Background Art

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

[0003] In inkjet printing operations, a predetermined ejection amount is generally set for the nozzle, and then the nozzle is controlled to eject according to the predetermined ejection amount. However, this will cause a problem, that is, the actual amount of ink ejected by the nozzle is not always consistent with the predetermined ejection amount, and sometimes there will be deviations, which will affect the effect of the inkjet operation.

[0004] If the deviation is to be corrected, the actual injection volume of the nozzle needs to be detected to compare with the predetermined injection volume, and then the error correction process is performed.

[0005] However, in the process of detecting the actual ejection amount of the nozzle, since the nozzle may be blocked or not smooth when ejecting ink, it is difficult to accurately detect the actual ejection amount, which increases the difficulty of the detection work. At present, no effective solution has been found, so it is a problem that needs to be solved urgently. Summary of the invention

[0006] An object of embodiments of the present invention is to solve the above-mentioned problems and provide advantages which will be described later.

[0007] Another object of the embodiments of the present application is to provide an inkjet detection structure and an inkjet device, which can be used to detect the actual inkjet volume of the nozzle and improve the detection accuracy of the actual inkjet volume.

[0008] In a first aspect, an embodiment of the present application provides an inkjet detection structure, including:

[0009] A detection panel having an inkjet detection area and a test spraying area, wherein the inkjet detection area is provided with a receiving hole penetrating through the upper and lower sides of the operation panel;

[0010] A weighing tray, the weighing tray is accommodated in the accommodation hole;

[0011] A weighing scale is connected to the weighing tray.

[0012] The inkjet detection structure of the embodiment of the present application is provided with a detection panel having an inkjet detection area and a test spraying area. Therefore, the nozzle can first be directed toward the test spraying area for spraying until the ink is sprayed smoothly, and then ink is sprayed toward the weighing tray located in the inkjet detection area. In this way, the ink actually 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 obtaining the actual injection amount, the deviation weight between the actual injection amount and the old predetermined injection amount can be used to correct the deviation and correct the predetermined injection amount of the nozzle to be consistent with the actual injection amount, thereby ensuring precise control of the actual inkjet of the nozzle.

[0014] In some technical solutions, the inkjet detection structure also includes an operating table, and the detection panel is installed on the operating table.

[0015] In some technical solutions, the operating table has a first mounting hole that passes through the upper and lower sides of the operating table, and the operating panel is connected to the first mounting hole to be mounted on the operating table.

[0016] In some technical solutions, the inkjet detection structure further includes: an ink discharger, one end of which is recessed inward to form an ink discharge groove, and the notch of the ink discharge groove is located in the test spraying area.

[0017] In some technical solutions, the test spraying area is provided with a second mounting hole, and the ink discharger is installed in the second mounting hole.

[0018] In some technical solutions, a predetermined distance is provided between the detection panel and the weighing scale to form a accommodating space for accommodating the ink discharger, thereby making the structure of the inkjet detection structure more compact. On this basis, the other end of the ink discharger passes through the second mounting hole and extends into the accommodating space. More specifically, the other end of the ink discharger is located above the weighing scale after extending into the accommodating space.

[0019] When a predetermined distance is provided between the detection panel and the weighing scale, in some technical solutions, the inkjet detection structure further comprises a tray seat, and the weighing scale is connected to the weighing tray via the tray seat.

[0020] In some technical solutions, the interior of the tray seat is hollow to reduce weight.

[0021] In some technical solutions, one end of the tray seat is connected to the weighing tray, and the other end is connected to the weighing scale.

[0022] In some technical solutions, the inkjet detection structure further includes: a support frame, and the operating table is installed on the upper end of the support frame.

[0023] In some technical solutions, the support frame includes a bottom plate, a left support member, and a right support member;

[0024] The lower ends of the left support member and the right support member are both connected to the upper end of the bottom plate.

[0025] In some technical solutions, the left support member is in a plate shape, and the right support member is in a plate shape.

[0026] In some technical solutions, the support frame also includes a connecting member, and the rear sides of the left support member and the right support member are both connected to the connecting member.

[0027] In some technical solutions, the connecting member is in the shape of a plate.

[0028] In some technical solutions, the inkjet detection structure further includes: a scale fixing member, and the weighing scale is connected to the bottom plate through the scale fixing member. Specifically, the lower end surface of the weighing scale is connected to the upper end of the scale fixing member, and the lower end of the scale fixing member is fixedly connected to the upper end of the bottom plate.

[0029] In some technical solutions, the number of the scale fixing parts is 4, which are respectively installed at the 4 corners.

[0030] In some technical solutions, the scale fixing member includes a fixing plate, a shockproof member and a horizontal adjustment nut.

[0031] In some technical solutions, the inkjet detection structure also includes a cover that can cover the weighing tray, which can protect the tray. When weighing is required, the cover is opened for detection, and when weighing is not required, the cover is closed to protect the tray and prevent the tray from being damaged by external forces or contaminated by dust.

[0032] In some technical solutions, the detection area is movably connected or detachably connected to the detection area.

[0033] In a second aspect, an embodiment of the present application further provides an inkjet device, comprising:

[0034] The inkjet detection structure described in the first aspect of the embodiment; and

[0035] A nozzle can be used to eject ink.

[0036] The beneficial effects that can be achieved by the embodiments of the present invention include:

[0037] The inkjet detection structure of the embodiment of the present application can make the nozzle spray ink in the test spray area before spraying ink to the inkjet detection area, and then perform inkjet detection in the inkjet detection area after no adverse phenomena occur, which is conducive to the implementation of the detection operation. Specifically, the inkjet detection structure of the embodiment of the present application is provided with a detection panel having an inkjet detection area and a test spray area, so the nozzle can be sprayed toward the test spray area first, until the ink is sprayed smoothly, and then the ink is sprayed toward the weighing tray located in the inkjet detection area, thereby obtaining the ink actually sprayed by the nozzle, and detecting the accurate actual spraying amount through the weighing scale.

[0051] <Inkjet Detection Structure 10>

[0052] In a first aspect, an embodiment of the present application provides an inkjet detection structure 10, comprising:

[0053] A detection panel 100 having an inkjet detection area 101 and a test spraying area 102, wherein the inkjet detection area 101 is provided with a receiving hole 1011 penetrating through the upper and lower sides of the operation panel; illustratively, the inkjet detection area 101 and the test spraying area 102 are sequentially arranged on the detection panel 100 from left to right;

[0054] A weighing tray 110, wherein the weighing tray 110 is accommodated in the accommodation hole 1011; illustratively, the weighing tray 110 is substantially in the shape of a disc;

[0055] The weighing scale 120 is connected to the weighing tray 110 ; illustratively, the upper end of the weighing scale 120 is connected to the lower end of the weighing tray 110 , and the upper end of the weighing tray 110 faces the upper side of the accommodating hole 1011 .

[0056] When using the inkjet detection structure 10 in the embodiment of the present application, the nozzle of the inkjet device can spray ink toward the weighing tray 110, and then the actual spraying amount can be obtained through the weighing scale 120.

[0057] Since the nozzle may be clogged or not smooth when spraying ink, it is difficult to detect the actual amount of ink sprayed. Therefore, before spraying ink in the inkjet detection area 101, the nozzle is first sprayed in the test spray area 102, and after there is no adverse phenomenon, the inkjet detection is performed in the inkjet detection area 101, which is conducive to the implementation of the detection operation. Specifically, the inkjet detection structure 10 of the embodiment of the present application is provided with a detection panel 100 having an inkjet detection area 101 and a test spray area 102, so the nozzle can be sprayed toward the test spray area 102 first, until the ink is sprayed smoothly, and then the ink is sprayed toward the weighing tray 110 located in the inkjet detection area 101, thereby obtaining the ink actually sprayed by the nozzle, and detecting the accurate actual spray amount through the weighing scale 120.

[0058] It can be understood that after obtaining the actual injection amount, the deviation weight between the actual injection amount and the old predetermined injection amount can be used to correct the deviation and correct the predetermined injection amount of the nozzle to be consistent with the actual injection amount, thereby ensuring precise control of the actual inkjet of the nozzle.

[0059] In addition, the weighing tray 110 is relatively independent, and is easy to remove, unload, and clean.

Figure 3 In the example, two first grooves 1012 are provided, respectively located on the left and right sides of the accommodating hole 1011 .

[0063] In some embodiments, the bottom surface of the first groove 1012 is flush with the upper opening of the receiving hole 1011. This facilitates the placement and removal of the weighing tray 110. The upper end of the first groove 1012 is open, and the side facing the receiving hole 1011 is also open. For example, the first groove 1012 on the left side has its right side facing the receiving hole 1011, so it is open.
