Description

Technical Field

[0001] The present invention relates to the technical field of display modules, and in particular to a method for adding automatic conductivity testing to a two-in-one machine. Background Art

[0002] Currently, the conductivity test of the main clips and clips of the LCD display module is generally carried out by manual testing. This method requires an increase in manpower in the workshop and may also lead to personnel missing inspections, resulting in products with poor conductivity flowing into downstream clients, causing problems in the electronic equipment after installation.

[0003] Therefore, the prior art has defects and needs to be improved. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for adding automatic continuity testing to a two-in-one machine.

[0005] The technical solution of the present invention is as follows: The present invention provides a method for adding automatic conductivity testing to a two-in-one machine, comprising the following steps: Step 1: providing a two-in-one machine, arranging a conductivity test mainboard and a needle mold carrier board matching the number of detection stations of the two-in-one machine on the two-in-one machine, the needle mold carrier board being used to carry a test needle mold, the test needle mold being electrically connected to a test mainboard, and the test mainboard being electrically connected to the two-in-one machine;

[0006] Step 2: After the two-in-one machine scans the QR code of the display module, it starts to perform a continuity test on the display module. The continuity test motherboard is electrically connected to the display module through the test needle mold, and the test result is sent to the two-in-one machine. If the test is qualified, it will proceed to step 3. If the test is unqualified, the display module will be discarded;

[0007] Step 3: Carry out lighting test, TP test and display screen test on the display module in sequence. If each test is qualified, the display module will be lowered normally. If any item fails, the display module will be judged as unqualified and discarded.

[0008] Furthermore, in step 1, the continuity test mainboard is connected to the two-in-one machine through serial communication, and the instructions for starting the test, ending the test, passing the test, and failing the test are set.

[0009] By adopting the above scheme, the beneficial effect of the present invention is that an automatic conductivity test is added to the two-in-one machine, and the display module can be automatically tested for conductivity before performing lighting test, TP test and screen display test, thereby improving the test efficiency and avoiding the occurrence of missed conductivity tests. DETAILED DESCRIPTION

[0010] The present invention is described in detail below in conjunction with specific embodiments.

[0011] In this embodiment, the present invention provides a method for adding automatic conductivity testing to a two-in-one machine, including: Step 1: Provide a two-in-one machine for performing lighting test, TP (touch) test and screen display test, and set a conductivity test mainboard and a pin mold carrier board that match the number of detection stations of the two-in-one machine on the two-in-one machine. For example, if 16 display modules can be detected simultaneously on the two-in-one machine, then the corresponding number of conductivity test mainboards and pin mold carrier boards is 16. The pin mold carrier board is used to carry the test pin mold, the test pin mold is electrically connected to the test mainboard, and the test mainboard is electrically connected to the two-in-one machine. Specifically, the conductivity test mainboard is connected to the two-in-one machine by serial communication, and the instructions for starting the test, ending the test, passing the test, and failing the test are set.

[0012] Step 2: After the two-in-one machine scans the QR code of the display module, it starts to perform a conductivity test on the display module. At this time, the conductivity test mainboard is electrically connected to the display module through the test pin mold. The two-in-one machine controls the conductivity mainboard to perform a conductivity test on the main buckle and negative buckle of the display module. Subsequently, the conductivity test mainboard sends the test results to the two-in-one machine. If the test is qualified, it proceeds to step 3. If the test fails, the display module is discarded.

[0013] Step 3: Carry out lighting test, TP test and display screen test on the display module in sequence. If each test is qualified, the display module will be lowered normally. If any item fails, the display module will be judged as unqualified and discarded.

[0014] In summary, the beneficial effect of this solution is that by adding automatic continuity test to the two-in-one machine, the display module can be automatically tested for continuity before the lighting test, TP test and screen display test, which improves the test efficiency and avoids the leakage of continuity test.

[0015] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
