Description

Technical Field

[0001] The present invention relates to the technical field of camera module detection, and in particular to a distributed multi-station machine light source spot inspection method. Background Art

[0002] The light source inspection of the camera module mainly involves the use of an optical imaging vision solution consisting of a 4K zoom lens, a Gigabit industrial camera, and a visual light source to obtain high-quality images, clearly illuminate defective areas, and quickly identify defects in photosensitive components. This inspection solution can adjust the configuration according to different inspection requirements to meet the defect inspection of other accessories such as mobile phone casings. Specifically, the 4K zoom lens can provide clear visual effects, while the Gigabit industrial camera is responsible for capturing these high-quality images.

[0003] The camera module has strict requirements on the light source during testing (burning). There is a special inspection software to test the light source. If it is qualified, the light source inspection qualification time will be updated in the local registry. The normal inspection software will check this time before lighting the module. If it exceeds 24 hours, the inspection is not allowed and an alarm is triggered to remind employees to inspect the light source. However, on a distributed multi-station machine, a group of light sources needs to be inspected N times (N is the number of test machines), resulting in a certain waste of production capacity. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0005] To achieve the above object, the present invention provides the following technical solution: a distributed multi-station machine light source inspection method, comprising the following steps:

[0006] Step 1: Write the inspection information;

[0007] Step 2: Modify the light source inspection path of the test software;

[0008] Step 3: Encrypt inspection information;

[0009] Step 4: Add one-key inspection to the industrial control software;

[0010] Step 5: Product classification.

[0011] As a further embodiment of the present invention: in step 1,

[0012] Step 1-1, write the inspection information that originally needs to be written into the local registry into a document named Light Source Certificate;

[0013] Step 1-2, store and back up the light source certificate with inspection information.

[0014] As a further solution of the present invention: in step 1-1, the inspection information written in the light source certificate includes the qualified data of the product.

[0015] As a further solution of the present invention: in step 2,

[0016] In step 2-1, the light source inspection information detection path of the test software is changed from the registry to the light source inspection certificate, and the light source inspection certificate comes from step 1-1.

[0017] As a further solution of the present invention: in step 3,

[0018] Encrypt and hide the light source certificate with inspection information, and use uppercase and lowercase letters, numbers and special characters to form an unlocking password;

[0019] Step 3-1: During subsequent decryption, if the decryption exceeds the set time or number of decryption attempts, the test software will stop running and will require re-authorization from the authorization center when it is re-enabled.

[0020] As a further solution of the present invention: in step 3, the method of encrypting the inspection information includes but is not limited to using the encryption function of the software, using third-party encryption software, modifying the file extension disguise, using hardware encryption equipment, and utilizing the encryption function of the cloud storage service.

[0021] As a further solution of the present invention: in step 4,

[0022] Step 4-1, select all modules in a test machine and block the rest;

[0023] Step 4-2, perform a complete test process on the selected module;

[0024] Step 4-3, copy the newly generated light source certificate in the selected test machine to the industrial computer for backup;

[0025] Step 4-4, distribute the light source certificate to other test machines.

[0026] As a further solution of the present invention: in step 4-3,

[0027] The source of the newly generated light source certificate in the test machine is the qualified light source information obtained after the test by the test machine in step 4-2. No light source certificate will be generated for the light source that fails the test.

[0028] As a further solution of the present invention: in step 4-4,

[0029] Step 4-41, after the remaining test machines obtain the certificate of the light source that has passed the test, they continue to test the light source that has passed the test in step 4-2, and no longer test the light source that has not passed the test in step 4-2.

[0030] As a further solution of the present invention: in step 5,

[0031] Light sources that have passed the tests of all test machines enter the next production process, and light sources that have not passed the tests are recycled or reworked.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] In the present application, the inspection information that originally needs to be written into the local registry is written into a document named as the light source certificate, which contains qualified inspection information. When multiple subsequent test machines inspect the camera module in turn, the information of the light source certificate can be used to inspect the passing light source. The qualified light source continues to enter the next test machine for subsequent testing, and when the unqualified light source enters the next test machine, the test machine does not inspect the light source through the entered light source certificate information. This method can avoid the problem of waste of production capacity caused by repeated inspection of unqualified light sources by distributed multi-station machines. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Step 1: Write the inspection information;

[0038] Step 2: Modify the light source inspection path of the test software;

[0039] Step 3: Encrypt inspection information;

[0040] Step 4: Add one-key inspection to the industrial control software;

[0041] Step 5: Product classification.

[0042] See also Figure 1 , in step 1,

[0043] Step 1-1, write the inspection information that originally needs to be written into the local registry into a document named Light Source Certificate;

[0044] Step 1-2, store and back up the light source certificate with inspection information. The purpose of storage is to facilitate subsequent use, and the purpose of backup is to compare or replace the backup data when abnormalities occur in subsequent data information.

[0045] See also Figure 1 In step 1-1, the inspection information written in the light source certificate contains the qualified data of the product.

[0046] See also Figure 1 , in step 2,

[0047] In step 2-1, the light source inspection information detection path of the test software is changed from the registry to the light source inspection certificate, and the light source inspection certificate comes from step 1-1.

[0048] See also Figure 1 , in step 3,

[0049] Encrypt and hide the light source certificate with inspection information, and combine uppercase and lowercase letters, numbers and special characters to form an unlocking password. By encrypting and hiding the light source certificate, it can effectively prevent operators from making changes and ensure data security;

[0050] See also Figure 1 , Step 3-1, during subsequent decryption, if the decryption exceeds the set time or number of decryption times, the test software will stop running, and the authorization center needs to re-authorize when it is re-enabled. By setting the decryption time and number of decryption times, the security of the data can be further guaranteed.

[0051] See also Figure 1 In step 3, the method of encrypting the inspection information includes but is not limited to using the encryption function of the software, using third-party encryption software, modifying the file extension disguise, using hardware encryption devices, and utilizing the encryption function of cloud storage services.

[0052] See also Figure 1 , in step 4,

[0053] Step 4-1, select all modules in a test machine and block the rest;

[0054] Step 4-2, perform a complete test process on the selected module;

[0055] Step 4-3, copy the newly generated light source certificate in the selected test machine to the industrial computer for backup;

[0056] Step 4-4, distribute the light source certificate to other test machines.

[0057] See also Figure 1 , in step 4-3,

[0058] The source of the newly generated light source certificate in the test machine is the qualified light source information obtained after the test machine test in step 4-2. The light source that fails the test will not generate a light source certificate. The qualified light source information obtained after the test machine test can be directly used in subsequent tests.

[0059] See also Figure 1 , in step 4-4,

[0060] In step 4-41, after the other test machines obtain the certificate of the light source that has passed the test, they continue to test the light source that has passed the test in step 4-2, and no longer test the light source that has not passed the test in step 4-2. This method can avoid repeated inspections of light sources and reduce waste of production capacity.

[0061] See also Figure 1 , in step 5,

[0062] Light sources that have passed the tests of all test machines enter the next production process, and light sources that have not passed the tests are recycled or reworked.

[0063] To summarize, by writing the inspection information that originally needed to be written into the local registry into a document named light source certificate, which contains qualified inspection information, when multiple test machines subsequently inspect the camera module in turn, the information on the light source certificate can be used to inspect the light source that passes through, and the qualified light source continues to enter the next test machine for subsequent testing, while the unqualified light source will not be inspected by the next test machine through the entered light source certificate information when entering the next test machine. This method can avoid the problem of waste of production capacity caused by repeated inspection of unqualified light sources by distributed multi-station machines.
