Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
In the actual operation process of the automatic detection of the LED, the LED monomer is required to be welded on the LED board firstly, and then the LED monomer on the LED board is required to be detected. Therefore, in the actual detection process, the number of the LED single bodies detected in a single time is different. This requires the LED board to be sized to accommodate the inspection requirements. However, in the LED automatic detection device on the market, only a single LED board can be used for detection, which reduces the application range of the LED automatic detection device.
In view of the above problems, the applicant has found, after keen thinking, that the conventional automatic LED inspection apparatus cannot inspect LED boards using a plurality of types of LED boards, and that the inspection apparatus cannot use more LED boards because the conveyance mechanism for conveying LED boards cannot be adjusted according to the size of the LED boards.
Therefore, the applicant finds in research that if the conveying mechanism in the automatic LED detection device can be adjusted according to the size of the LED board, the automatic LED detection device can meet more detection requirements, so that the detection range of the LED device is widened, and the detection efficiency is improved.
The scheme is further illustrated by the following examples:
as shown in fig. 1, the LED automatic inspection apparatus 1000 includes a carrying member 200 for transmitting the LED board 100, a power supply assembly 300 for supplying power to the LED board 100, and an inspection member 400 for inspecting the LED board 100.
The LED board 100 is used for welding LED single bodies to be detected, and the LED single bodies may be a single LED or an LED strip. When the detection is finished, the LED panel 100 is manually disassembled, and then the LED is used in the next process. In addition, the power supply assembly 300 may supply power to the LED board 100, and may also supply power to the LED single body on the LED board 100.
As shown in fig. 2 and 3, the conveying member 200 includes a widening rail assembly 210 for conveying the LED board 100, a front barrier assembly 230 for positioning a front side of the LED board 100, and a rear barrier assembly 250 for positioning a rear side of the LED board 100.
Specifically, the width-adjusting rail assembly 210, the front barrier assembly 230 and the rear barrier assembly 250 are all used for positioning the LED board 100, and the positioning position can be adjusted according to the size of the LED board 100, so that the transporting member 200 can better transport the LED board 100. When the LED board 100 is transported to the inspection position, the front barrier assembly 230 and the rear barrier assembly 250 position the LED board 100 such that the LED board 100 remains stationary during the inspection process, preventing an error in the inspection.
As shown in fig. 2, the inspection part 400 includes an inspection camera 410 for inspecting brightness of the LED units on the LED board 100, an inspection bracket assembly 420 for mounting the inspection camera 410, an inspection guide 430, and an inspection driving assembly 440 for driving the inspection bracket assembly 420 to slide back and forth on the inspection guide 430. The detection camera 410 is located directly above the widening rail assembly 210.
Wherein the inspection camera 410 can translate left and right on the inspection bracket assembly 420. As shown in fig. 7, the area detected by the detection camera 410 at a single time is the detection area 411, and therefore, the detection area of the detection camera 410 cannot completely cover the LED board 100 at a single time. In order for the inspection camera 410 to be able to completely inspect the LED units on the LED board 100, the inspection camera 410 needs to be moved back and forth in the left-right direction and the front-back direction.
As shown in fig. 3 and 4, the front block assembly 230 includes a front support block 231 for supporting the LED board 100 and a front positioning block 232 for providing a front position for the LED board 100. The front support block 231 is used for supporting the LED board 100, and ensures that the LED board 100 does not deform under the pressure applied by the power supply assembly 300.
As shown in fig. 2, 3 and 6, the width-adjusting track assembly 210 includes a left track 211, a right track 212, a left belt 221 disposed on the left track 211, and a right belt 222 disposed on the right track 212. In the present embodiment, the transport member 200 further includes a base 201. And a mounting shaft 202 for mounting the left rail 211 and the right rail 212 is arranged on the base 201. As shown in fig. 6, the left rail 211 and the right rail 212 may translate on the mounting shaft 202 to accommodate the size of the LED board 100 to complete the transport. The principle of the transport and track widening of the transport member 200 can be found in the patent application with application publication No. CN106335738A, which is incorporated herein by reference in its entirety.
As shown in fig. 2 and 3, the rear stop assembly 250 includes a rear positioning block 251 for positioning the rear portion of the LED board 100, a rear stop rail 253, and a rear stop driving portion 252 for driving the rear stop assembly 250 to move back and forth along the rear stop rail 253. The rear positioning block 251 can move back and forth along the rear rail 253 under the driving of the rear driving portion 252 according to the front and rear length of the LED board 100, so as to provide accurate positioning for the rear portion of the LED board 100.
As shown in fig. 2, 4 and 5, the power supply assembly 300 includes a front charging probe 310 and a rear charging probe 320 for supplying power to the LED board 100, and a power supply probe 330 for supplying power to the LED unit on the LED board 100. Since the LED single body of the LED board 100 is a single LED or an LED strip, when the LED single body is a single LED, the LED board 100 is powered by the front charging probe 310 and the rear charging probe 320, and the LED can be turned on; when the LED single body is an LED strip, the LED strip can be lighted by supplying power to the LED strip through the power supply probe 330.
As shown in fig. 4, a left positioning portion 213 for positioning the left side of the LED board 100 is disposed on the left guide rail 211.
As shown in fig. 1, the automatic LED detection device 1000 further includes an upper housing 510 for mounting the detection member 400 and a lower housing 520 for mounting the transport member 200.
In this embodiment, after the LED board 100 enters the left driving belt 221 and the right driving belt 222 of the conveying member 200, the rear stop assembly 250 moves the rear positioning block 251 upward by the air cylinder, so that the LED board 100 can continue to move forward. When the front end of the LED board 100 contacts the rear end of the front positioning block 232 reaching the front stop assembly 230, the left and right driving belts 221 and 222 stop driving, and the LED board 100 is stationary. At this time, the rear block assembly 250 positions the rear portion of the LED board 100 by the air cylinder. At this time, the rear charging probe 320 communicates with the LED board 100. Meanwhile, the left positioning portion 213 of the left guide rail 211 is moved rightward by the air cylinder to position the LED board 100. Subsequently, the front support block 231 moves upward by the air cylinder, supporting the LED panel 100. Meanwhile, the power supply assembly 300 and the power supply probe 330 move downwards under the action of the air cylinder to supply power to the LED board 100 or the LED strip on the LED board 100, and the LED lights up.
When the LED is turned on, the detection camera 410 starts to work, and the LED single body on the LED board 100 is detected above the LED board 100 under the driving of the detection driving component 440. After the detection of the detection camera 410 is completed, the power supply assembly 300 and the power supply probe 330 move upward under the action of the air cylinder, the left positioning portion 213 of the left guide rail 211 moves leftward under the action of the air cylinder, the front positioning block 232 moves downward under the action of the air cylinder, the front supporting block 231 moves downward under the action of the air cylinder, and the rear positioning block 251 is moved upward by the rear stop assembly 250 under the action of the air cylinder. At this time, the left and right belts 221 and 222 continue to drive, and the LED board 100 is conveyed forward. At this point, the detection is completed.
