[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] See also Figure 1-Figure 5 , a detection device for DOB light source detection, comprising a machine platform 10, on which a conveying element 110 for conveying a DOB light source board is arranged, and a limit position component 20 and a position correction component 30 are arranged on the machine platform 10;

[0025] The stopper assembly 20 is used to stop the DOB light source board from moving when the conveying element 110 drives the DOB light source board to move;

[0027] A detection module 40 for detecting power-on of the DOB light source panel is disposed above the conveying element 110 .

[0028] Working principle of the detection equipment: The conveying element is used to convey the DOB light source board to the first direction. When it is conveyed to the detection position, the BOD light source is blocked by the limit component to keep it at the detection position. At this time, it moves in the second direction through the position correction component. During this movement, the position correction component can push the DOB light source board at the detection position to move in the second direction to correct its position in the second direction in preparation for detection. During the detection, the detection module and the DOB light source board are powered on for detection, and the functional integrity is judged based on the lighting status of the LED light source in the DOB light source board.

[0029] See also Figure 3 The conveying element 110 includes a plurality of conveying rollers 111 arranged in a transverse arrangement. The front and rear ends of the conveying rollers 111 are rotatably arranged on the machine platform 10. The conveying rollers 111 are driven by an existing transmission method. For example, all the conveying rollers 111 are equipped with pulleys, and transmission belts are sleeved on all the pulleys. A motor is provided to drive any conveying roller 111 to rotate.

[0030] See also Figure 3 The limit assembly 20 includes a lifting element 210 disposed on the machine 10, and the lifting end of the lifting element 210 is connected to a limit plate 220, and the limit plate 220 is disposed between the two conveying rollers 111. The lifting element 210 adopts a cylinder. Before the detection, the cylinder drives the limit plate 220 to move upward. At this time, the limit plate 220 can block the BOD light source to keep it in the detection position. When the detection is completed, the cylinder drives the limit plate 220 to move downward to release the blockage, so that the BOD light source after the detection follows the conveying element 110 to move along the first direction.

[0031] See also Figure 2 The position correction assembly 30 includes a first movable seat 310 movably arranged on the machine table 10, the first movable seat 310 moves along the axial direction of the conveying roller 111, a connecting plate 320 is arranged on the first movable seat 310, the connecting plate 320 is located below the conveying roller 111, a pushing plate 330 is arranged above the conveying element 110, a connecting portion 331 is arranged on the pushing plate 330, and the connecting portion 331 passes through the two conveying rollers 111 and is fixedly connected to the connecting plate 320;

[0032] The platform 10 is provided with a first linear motion assembly 350 , and the first linear motion assembly 350 is used to drive the first moving seat 310 to reciprocate along the axial direction of the conveying roller 111 .

[0033] When the DOB light source board is blocked by the limiting plate 220, the first direction position of the DOB light source board is correct. At this time, the position in the second direction is adjusted by the position correction component 30. The adjustment is achieved by the first linear moving component 350 driving the first moving seat 310, the connecting plate 320 and the pushing plate 330 to move together. During the movement, the pushing plate 330 can push the DOB light source board located at the conveying element 110 to move.

[0034] Further, the first linear moving assembly 350 includes synchronous wheels 351 arranged at intervals in front and back, the synchronous wheels 351 are rotatably arranged on the machine 10, a synchronous belt 352 is sleeved on the front and rear synchronous wheels 351, a belt clamp 354 fixedly connected to the synchronous belt 352 is installed on the first moving seat 310, and a driving motor 353 for driving the synchronous wheels 351 to rotate is arranged on the machine 10. When the driving motor 353 is started to work, it can drive the synchronous wheel 351 to rotate, thereby driving the synchronous belt 352 to operate, so as to drive the first moving seat 310 to move through the belt clamp 354.

[0035] Furthermore, the first linear motion assembly 350 can be driven by an existing air cylinder or electric cylinder.

[0036] See also Figures 3 to 5 The detection module 40 includes a second movable seat 410 that can move forward and backward relative to the machine 10, and a third movable seat 420 that can move left and right relative to the second movable seat 410 is arranged on the second movable seat 410, and a second linear moving component 430 for driving the third movable seat 420 to move left and right relative to the second movable seat 410 is arranged on the second movable seat 410, and a third linear moving component 440 for driving the second movable seat 410 to move forward and backward relative to the machine 10 is arranged on the machine 10;

[0038] The test mount 450 is provided with a camera 50 for photographing the DOB light source board.

[0039] During the test, the second linear motion component 430 drives the third movable seat 420 to move left and right relative to the second movable seat 410, and its function is to adjust the left and right position of the test needle 470 so that the position of the test needle 470 corresponds to the power connection end of the DOB light source board. At the same time, the third linear motion component 440 drives the second movable seat 410 to move forward and backward relative to the machine 10, and its function is to adjust the front and rear position of the test needle 470 so that the position of the test needle 470 corresponds to the power connection end of the DOB light source board.

Of course, existing linear reciprocating motion devices, such as cylinders, electric cylinders, etc., can also be used for driving.

[0041] During testing, the test pin 470 is connected to the power supply circuit. Under the position adjustment of the second linear moving component 430 and the third linear moving component 440, when the test pin 470 corresponds to the power connection end of the DOB light source board, the linear element 460 drives the test pin 470 to move downward, so that the test pin 470 is connected to the power connection end of the DOB light source board to power the DOB light source board. After power supply, the LED light source in the DOB light source board will be lit normally. If it cannot be lit, it is judged to be a functional defect and a defective product.

[0042] The function of the camera 50 is to take pictures of the detection process so that an external image recognition device can identify the lighting status of the LED light source.
