Embodiment 1

[0050] See figure 1 , the present invention provides a liquid crystal module automatic inkjet device comprising: a controller 100, a first sensor 200, a second sensor 300, a first visual reader 400, a second visual reader 500 and an inkjet printer 600; It also includes a workpiece automatic alignment mechanism 700; the first sensor 200 is electrically connected to the workpiece automatic alignment mechanism 700; the first visual reader 400 is electrically connected to the inkjet printer 600; the second The sensor 300 is electrically connected to the second visual reader 500; the second visual reader 500 is electrically connected to the controller 100; the first sensor 200 is used to trigger the workpiece automatic alignment mechanism 700 Action; the execution end 710 of the workpiece automatic alignment mechanism 700 is used to adjust the placement position of the liquid crystal module Y on the conveyor belt C; the first visual reader 400 is used to identify the workpiece in t...

Embodiment 2

[0060] Such as image 3 As shown, in this embodiment, the workpiece automatic alignment mechanism 700 includes: a master form 710 and a cylinder 720 that is arranged on the opposite side of the form 710 and has a push plate 721 at its free end; the master form 710 and the cylinder 720 Said air cylinder 720 is oppositely arranged on both sides of the conveyer belt perpendicular to the conveying direction; said air cylinder acts to clamp said workpiece between said former and said push plate, and said workpiece completes position alignment; The position alignment is satisfied: when the workpiece passes directly under the nozzle of the inkjet printer, the part of the workpiece to be coded is relatively positive to the spraying position of the nozzle of the inkjet printer. The workpiece automatic alignment mechanism that matches the profile and the cylinder is used, and the liquid crystal module that can place the upstream station on the assembly line can automatically correct the...

Embodiment 4

[0066] This embodiment provides on the basis of the foregoing embodiments, a method for controlling an automatic coding device for a liquid crystal module, the method comprising the following steps:

[0067] The first sensor recognizes that the liquid crystal module has reached the executable area of ​​the workpiece automatic alignment mechanism;

[0068] The automatic workpiece alignment mechanism operates to adjust the placement position of the liquid crystal module on the conveyor belt to a uniform setting position;

[0069] After the first visual reader recognizes that the position of the liquid crystal module is aligned, it sends an action trigger signal to the inkjet printer;

[0070] The inkjet printer operates the inkjet code after obtaining the action trigger signal;

[0071] When the second sensor recognizes that the liquid crystal module arrives at the recognizable area of ​​the second visual reader, it sends a trigger signal for inkjet reading to the second visual...

Abstract

The invention aims at providing a liquid crystal module automatic code spraying device and a control method thereof. A workpiece automatic alignment mechanism is introduced, and the technical problemthat the production line relies on manual correcting of the workpiece putting position is solved. The liquid crystal module automatic code spraying device structurally comprises a controller, a firstsensor, a second sensor, a first visual reader, a second visual reader, a code spraying machine and the workpiece automatic alignment mechanism, and the method comprises the following steps that the first sensor recognizes that a liquid crystal module arrives at the alignment execution area; the workpiece automatic alignment mechanism acts; the first visual reader recognizes the position alignment, then, the code spraying machine is triggered to spray codes, when the second sensor recognizes that the liquid crystal module arrives the recognizing area, a trigger signal is sent to the second visual reader, the second visual reader reads the code spraying information, and the recognizing result is fed back to a controller; and the controller marks the code spraying information and reads the abnormal liquid crystal module, and warning is given for the liquid crystal module with the abnormal code spraying information reading. The production benefit of the liquid crystal module product can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal module inkjet coding, in particular to an automatic liquid crystal module inkjet inkjet device and a control method thereof. Background technique [0002] With the rise of the digital product industry such as mobile phones, product information tracking in the form of labeling or spraying codes on products has become a necessity in the industry, especially the implementation of code spraying on LCD modules has become an indispensable part of the assembly line in the industry homework link. In the prior art, when the liquid crystal module is sprayed on the assembly line, the practitioners usually need to use manual operation to align the product with the help of the stopper near the station. Because the operation force is not easy to control during the alignment operation, Liquid crystal module products have a greater risk of rupture; further, the inkjet operation requires high accuracy in t...
