In this embodiment, the X-ray positioning device 20 may include an inspection platform 21 , a light emitting unit 23 , an image recording unit 25 and a processing control unit (not shown). As shown in Fig. 1 and Fig. 2, the inspection platform 21 is arranged on the first placement platform 71, and the inspection platform 21 has a first side 21-1 and a second side 21-2 opposite to each other, and the light emitting unit 23 is set On the first side 21-1, the image capture unit 25 is disposed on the second side 21-2, that is, the light emitting unit 23 and the image capture unit 25 are respectively disposed on opposite sides of the inspection platform 21 . In the embodiment shown in FIG. 2 , the light emitting unit 23 is located above the inspection platform 21 , and the image capture unit 25 is located below the inspection platform 21 , but the present invention is not limited thereto. In other embodiments, the positions of the light emitting unit 23 and the image capturing unit 25 can also be interchanged.

In this embodiment, the light emitting unit 23 is an X-ray light source for forming a photosensitive area 22 (or field of view (FOV)) on the inspection platform 21, and the photosensitive area 22 can be, for example, A4 size (about 31cm x 25cm), but the utility model is not limited thereto. In the embodiment of the present invention, the photosensitive range 22 can be adjusted according to actual needs, and is not limited to the above-mentioned size. The image capture unit 25 is, for example, a CCD lens for capturing sensing images within the photosensitive range 22 . For example, when the circuit board is transferred to the inspection platform 21 of the X-ray positioning device 20 by the first transfer unit 31, the X-ray light source is emitted through the light emitting unit 23, and the image recording unit 25 can capture the circuit board The sensing image formed by the plate in the photosensitive range 22 . In addition, the processing control unit is used for receiving and analyzing the sensing image.

As shown in Figure 1, in this embodiment, the first transfer unit 31 is set on a second placement table 72, the second placement table 72 is opposite to the first placement table 71, and the first placement table 72 The transfer unit 31 is, for example, a six-axis robotic arm. The first conveying unit 31 can, for example, hold the circuit board 90 in a suction manner, and can rotate or turn over the circuit board 90 to adjust the circuit board 90 to a correct feeding position. The processing and control unit of the X-ray positioning device 20 is connected to the first conveying unit 31, and the processing and controlling unit controls the first conveying unit 31 to adjust the circuit board 90 according to the sensed image, and adjusts the circuit board 90 to be correctly fed. position, and control the first transfer unit 31 to transfer and place the circuit board in the waiting area 40 . For example, the first transfer unit 31 can directly transfer the circuit board to the waiting area 40 , adjust the position of the circuit board 90 or turn over the circuit board 90 .

3A to 3D show four situations in which the first transfer unit 31 transfers a circuit board 90 from the feeding area 10 to the X-ray positioning device 20 (on the inspection platform 21 ) in an embodiment of the present invention. In this embodiment, the back-end processing device 50 is, for example, a target drilling machine, and (the processing control unit of) the X-ray positioning device 20 can control the first transmission unit 31 to The circuit board 90 performs different actions to ensure that when the circuit board 90 is subsequently delivered to the back-end processing device 50 , feeding is performed at a correct position.

In this embodiment, the circuit board 90 may include two positioning holes A1, A2 and the fool-proof hole B, as shown in FIGS. right triangle. The X-ray positioning device 20 can first check the positions of the positioning holes A1 and A2, and then check the positions of the positioning hole A1 and the fool-proof hole B; or, it can first check the position of the positioning hole A1 and the fool-proof hole B Then check the positions of the positioning holes A1 and A2 to properly adjust the position of the circuit board 90 . The details will be described below.

The circuit board 90 shown in FIG. 3A is with the front side 901 facing upwards, and the positions of the positioning holes A1, A2 and the fool-proof hole B are for transferring the circuit board 90 to the back-end processing device 50 (for example: drilling target) machine) can be directly processed in the correct position. That is, when the first transfer unit 31 transfers the circuit board 90 from the feeding area 10 to the inspection platform 21 of the X-ray positioning device 20, light (X-ray) is emitted through the light-emitting unit 23, and the image capture When the sensing image formed by the circuit board 90 in the photosensitive range 22 captured by the recording unit 25 is shown in FIG. District 40.

In some embodiments, the processing control unit can control the first transfer unit 31 to rotate the circuit board 90 according to the sensed image.

The circuit board 90 shown in FIG. 3B has the front side 901 facing upwards, and the positions of the positioning holes A1, A2 and the fool-proof hole B are consistent with the position of the circuit board 90 being transferred to the back-end processing device 50 (for example: a target drilling machine) ) differ by 180 degrees from the correct position for handling. Therefore, when the sensing image formed by the circuit board 90 in the photosensitive range 22 is captured by the image capture unit 25 as shown in FIG. After first rotating 180 degrees, it is sent to the waiting area 40 again.

In other embodiments, the processing control unit can control the first transfer unit 31 to turn over the circuit board 90 according to the sensing image.

Since the X-ray positioning device 20 checks the positions of the positioning holes A1 and A2 and the positions of the positioning hole A1 and the fool-proof hole B, the processing control unit is It can be judged that no matter how the circuit board 90 is rotated, it cannot be adjusted to the correct feeding position. Therefore, when the sensing image formed by the circuit board 90 in the photosensitive range 22 is captured by the image capture unit 25 as shown in FIG. Turn over to be the front side, and send to the waiting area 40 again.

The circuit board 90 shown in FIG. 3D also has the back surface 902 facing upwards, but the positions of the positioning holes A1 , A2 and the foolproof hole B are 180 degrees different from those shown in FIG. 3C . Similarly, since the X-ray positioning device 20 checks the positions of the positioning holes A1, A2 and the positions of the positioning hole A1 and the fool-proof hole B, the processing control unit can judge that no matter how the circuit board 90 is rotated, it cannot Adjust to the correct feeding position. Therefore, when the sensing image formed by the circuit board 90 in the photosensitive range 22 is captured by the image capture unit 25 as shown in FIG. Turn over to be the front side, and then the circuit board 90 is rotated 180 degrees before being delivered to the waiting area 40 .
