Description

Technical Field

[0001] This utility model relates to the technical field of CCD camera inspection equipment, and in particular to a CCD camera inspection equipment for printed patterns. Background Technology

[0002] After printing patterns and characters on home appliances and mobile phones, it is necessary to inspect the printed patterns and characters to avoid problems.

[0003] In existing technologies, most inspections are conducted manually. However, due to the small size of printed characters, using a magnifying glass for inspection can easily cause eye fatigue, lead to misjudgments of printed characters, and result in difficult operation and low efficiency. Therefore, we propose a CCD camera inspection device for printed patterns to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of manual inspection, which is often difficult to operate and inefficient due to the small size of printed characters, the use of magnifying glasses, eye fatigue, misjudgment of printed characters, and the need for manual operation. Therefore, this invention proposes a CCD camera inspection device for printed patterns.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A CCD camera inspection device for printed patterns, comprising:

[0007] A testing box with an opening on one side;

[0008] The mounting base is fixedly installed on the top inner wall of the testing box;

[0009] The mounting plate is installed on the mounting base, and the CCD camera is fixedly installed on the bottom of the mounting plate.

[0010] A ring-shaped supplementary light is installed on the testing box;

[0011] The test stand is installed on the bottom inner wall of the test chamber;

[0012] The connecting mechanism, located on the mounting plate, is used to connect and fix the mounting plate to the mounting base.

[0013] Preferably, the connecting mechanism includes two locking rods, and locking grooves are provided on both sides of the mounting base. One end of each locking rod is engaged with one of the two locking grooves.

[0014] Preferably, the mounting plate has horizontal holes on both sides, the outer sides of the two locking rods are slidably connected to the inner walls of the two horizontal holes respectively, and the top of the mounting plate has a slot for the mounting base to engage with the slot.

[0015] Preferably, a push-pull block is fixedly installed at one end of each of the two locking rods, and a spring is sleeved on the outside of each of the two locking rods. One end of the spring is fixedly connected to the push-pull block, and the other end of the spring is fixedly connected to the outside of the mounting plate.

[0016] Preferably, the inner walls on both sides of the testing box are provided with sliding grooves, and sliders are slidably installed in both sliding grooves, with the sliders fixedly connected to the ring-shaped supplementary light.

[0017] Preferably, a support plate is fixedly installed on the inner wall of the testing box, and an electric push rod is fixedly installed at the bottom of the support plate. The output shaft of the electric push rod is fixedly connected to the slider.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] The product to be tested is placed on the test bench and illuminated by a ring light. A CCD camera captures images of good products, which are then stored in the industrial control computer as samples. Each tested product is compared with the sample; products that match the sample are considered good, while those that do not are considered defective. An electric push rod drives a slider to move vertically, thereby adjusting the height of the ring light. Pulling two push-pull blocks away from each other stretches two springs and causes two locking rods to disengage from two locking slots. Then, pulling down the mounting plate disengages the mounting base from the slot, allowing the CCD camera to be removed for easy maintenance.

[0020] This invention is simple to operate, fast to test, does not cause eye fatigue, saves manpower, and improves efficiency. Attached Figure Description

[0029] Mounting base 2 is fixedly installed on the top inner wall of the testing box 1;

[0030] Mounting plate 3 is mounted on mounting base 2, and CCD camera 4 is fixedly mounted on the bottom of mounting plate 3;

[0031] A ring-shaped supplementary light 6 is installed on the detection box 1;

[0032] Test stand 7 is installed on the bottom inner wall of test box 1;

[0033] A connecting mechanism is provided on the mounting plate 3 and is used to connect and fix the mounting plate 3 and the mounting base 2.

[0034] In this embodiment, the connecting mechanism includes two locking rods 10, and locking grooves 9 are provided on both sides of the mounting base 2. One end of the two locking rods 10 is respectively engaged with the two locking grooves 9.
