Description

Technical Field

[0001] The invention relates to the technical field of mobile phone backlight panel detection, in particular to a mobile phone backlight panel detection device. Background Art

[0002] During the production process of mobile phone backlight panels, products often have quality problems such as foreign matter, spots, scratches, and misalignment. If these are not discovered during the production stage, they will affect the subsequent screen and even the use of the entire mobile phone. Therefore, after the mobile phone backlight panel is assembled, luminous detection is required to ensure the quality of the backlight panel. At present, many companies use workers to conduct visual inspections. First, the labor cost is high. In order to match the production rhythm, usually 3 to 5 people are required to conduct luminous inspections, resulting in high production costs for the company; second, through manual quality inspections, each person has different judgment standards for quality requirements, which is easy to cause misjudgment; third, because the inspection workers look directly at the strong light emitted by the backlight panel with their naked eyes for a long time, it causes damage to the eyesight of the inspection workers.

[0003] The Chinese invention with the publication number CN109000892A discloses a mobile phone backlight panel detection device. The patent includes a base plate, multiple columns, a colorimeter, a moving block, a transverse motor, and a longitudinal motor. The columns are installed on the base plate, and two transverse screws and two longitudinal screws are provided on the upper part of the columns. The transverse motor is installed on the columns and connected to a transverse screw. The longitudinal motor is installed on the columns and connected to a longitudinal screw. The transverse screws are provided with transverse nuts, which are connected to each other through transverse rods. The longitudinal screws are provided with longitudinal nuts, which are connected to each other through longitudinal rods. The invention uses devices such as screws and moving blocks, and the colorimeter can move on the horizontal plane to detect the backlight panels fixed on the fixture in turn. Multiple backlight panels can be detected at a time, which improves work efficiency. The quality of the backlight panel is judged by the colorimeter, eliminating subjective factors, and avoiding the use of human eyes to judge, protecting the eyes of workers.

[0004] However, the above patent has the following shortcomings. First, the colorimeter can be moved on the horizontal plane through devices such as screw rods and moving blocks to detect the backlight panels fixed on the fixture in turn. Multiple backlight panels can be detected at a time, but the backlight panels are placed horizontally. If the scratches on the surface of the backlight panels are irregular, direct light cannot directly display all the scratches on the backlight panels, thereby affecting the detection results. Secondly, during the detection and transportation process of the backlight panels, if there are stains on the surface, it will still affect the detection results, increasing the workload of the system detection and having limitations in use.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The present invention is provided with a fixing mechanism, and a supporting frame matching the size of the backlight panel is selected and adsorbed on the supporting block. The staff puts the backlight panel to be inspected on the supporting frame.

[0020] (2) The present invention is provided with a first fixed rod, a support block and a second fixed rod. The rotation of the circular column drives the fixed block to rotate, so that the first fixed rod, the support block and the second fixed rod are squeezed onto the arc plate, driving the sliding rod and the baffle on the arc plate to squeeze the press switch, so that the press switch drives the motor and the vacuum pump to turn on, and the motor drives the bristles on the hollow rod to rotate to clean the outer wall of the top of the rotating backlight panel.

When the top rod and the convex block rotate into the wave groove, the convex block will move up and down under the action of the wave groove, thereby driving the fixed frame to rotate up and down under the condition of the circular rod, which can change the illumination angle of the lighting lamp, enable better viewing of the surface condition of the backlight panel, and ensure the adequacy of the detection. When the bevel gear on the second fixed rod moves to the helical rack, the helical rack drives the bevel gear to rotate, which can drive the backlight panel fixed on the supporting frame to rotate, thereby changing the illumination angle of the lighting lamp, further improving the illumination condition of the backlight panel, facilitating the industrial camera to perform shooting and processing, and further improving the detection effect of the backlight panel.

[0049] Specifically, a baffle is installed on the outer wall of the other side of the sliding rod 13, and a compression spring 27 is sleeved on one side of the circumferential outer wall of the sliding rod 13. The outer walls on both sides of the compression spring 27 are respectively fixedly connected to the inner wall on one side of the filter housing 403 and the outer wall on one side of the baffle. A push switch 28 is installed on one side of the bottom inner wall of the filter housing 403. A controller is installed on the bottom inner wall of the filter housing 403. The push switch 28 is electrically connected to the signal input end of the controller through a wire. An air pump is installed on the outer wall of one end of the filter housing 403.

[0052] The specific method of use is as follows: first, select a support frame 805 that matches the size of the backlight panel, and adsorb it on the support block 802. The staff puts the backlight panel to be tested on the support frame 805. The arc-shaped extrusion block 806 and the buffer spring 807 on the support frame 805 can squeeze and fix the backlight panel to avoid movement during the subsequent detection process, thereby ensuring the normal operation of the detection work. Turn on the servo motor 6 to drive the circular column 10 to rotate, and the rotation of the circular column 10 drives the fixing block 14 to rotate, so that the first fixing rod 801, the support block 802 and the second fixing rod 803 are no longer in contact with the arc plate 12 but are squeezed onto the arc plate 12, thereby driving the sliding rod 13 and the baffle on the arc plate 12 to squeeze the press switch 28, thereby The switch 28 is pressed to start the motor 3 and the vacuum pump. The motor 3 drives the bristles 402 on the hollow rod 401 to rotate to clean the outer wall of the top of the rotating backlight panel. Since the backlight panel rotates around the circular column 10, the bristles 402 can fully clean the outer wall of the backlight panel. The air inlet groove on the hollow rod 401 absorbs the dust cleaned by the bristles 402 and enters the filter housing 403 through the air outlet groove. The filter screen 404 filters and collects the dust in the air. The bristles 402 pass through the scraping grooves on the cleaning housing 20 on the exhaust pipe 21 when rotating, and can impact and separate the dust attached to the bristles 402. The exhaust pipe 21 cleans the inside of the cleaning housing 20. The separated dust is sucked into the filter housing 403, which further improves the cleaning effect of the backlight panel. The circular column 10 drives the cleaned backlight panel to rotate again, and the second fixing rod 803 is separated from the arc plate 12, so that the motor 3 and the vacuum pump are turned off. At this time, the lighting lamp 16 and the industrial camera 17 are turned on to take pictures of the surface of the backlight panel to check the surface condition of the backlight panel, so as to deal with the backlight panel with scratches and defects on the surface. The inner wall of the protective cover 2 is provided with an annular groove 11, and the top rod 18 and the convex block 24 on the fixing frame 15 slide inside the annular groove 11. When the top rod 18 and the convex block 24 rotate into the wave groove 9, the convex block 24 will move up and down under the action of the wave groove 9, thereby driving the fixing frame 15 on the circular rod 19 When the bevel gear 804 on the second fixed rod 803 moves to the bevel rack 7, the bevel rack 7 drives the bevel gear 804 to rotate, which can drive the backlight panel fixed on the support frame 805 to rotate, changing the illumination angle of the illuminator 16, further improving the illumination of the backlight panel, and facilitating the industrial camera 17 to perform shooting and processing. The circular column 10 continues to rotate, and the support block 802 moves to the top of the arc-shaped limit plate 29, and the arc-shaped limit plate 29 supports the support block 802 to prevent the first fixed rod 801, the support block 802 and the second fixed rod 803 from rotating.The connecting column 22, the supporting spring 26 and the arc-shaped top block 25 are moved to the top groove 808 on the supporting block 802 and the supporting frame 805, and the backlight panel squeezed by the arc-shaped squeezing block 806 and the buffer spring 807 is lifted up, which is convenient for the staff to disassemble and install the backlight panel and improves the work efficiency.
