The unit 23 is disposed on the first side 21-1, and the image capturing unit 25 is disposed on the second side 21-2, that is, the light emitting unit 23 and the image capturing unit 25 are respectively disposed on the inspection platform 21 On both sides. In the embodiment shown in FIG. 2, the illumination unit 23 is located above the inspection platform 21, and the image recording unit 25 is located below the inspection platform 21, but the creation is not limited thereto. In other embodiments, the positions of the light emitting unit 23 and the image capturing unit 25 are also interchangeable.

In this embodiment, the light-emitting unit 23 is an X-ray source for forming a light-sensing range 22 (or a field of view (FOV)) on the inspection platform 21, and the light-sensing range 22 can be, for example, One A4 size (approx. 31 cm x 25 cm), but this creation is not limited to this. In the present embodiment, the photographic range 22 can be adjusted according to actual needs, and is not limited to the above size. The image capturing unit 25 is, for example, a CCD lens for capturing a sensing image in the photosensitive range 22. For example, when a circuit board is transmitted to the inspection platform 21 of the X-ray positioning device 20 by the first transmission unit 31, an X-ray source is emitted through the illumination unit 23, and the image recording unit 25 can capture the image. A sensing image formed by the board within the photographic range 22. In addition, the processing control unit is configured to receive and analyze the sensing image.

As shown in FIG. 1 , in the embodiment, the first transmitting unit 31 is disposed on a second placing table 72 , and the second placing table 72 is opposite to the first placing table 71 , and the first The transport unit 31 is, for example, a six-axis robot arm. The first transfer unit 31 can hold the circuit board 90, for example, in an adsorbed manner, and can rotate or flip the circuit board 90 to adjust the circuit board 90 to a proper feed position. The processing control unit of the X-ray positioning device 20 is connected to the first transmitting unit 31, and the processing control unit controls the first transmitting unit 31 to adjust the circuit board 90 according to the sensing image, and adjusts the circuit board 90 to one. The feed position is correctly controlled, and the first transfer unit 31 is controlled to transfer and place the board in the to-be-supplied area 40. For example, the first transfer unit 31 can directly transfer the circuit board to the to-be-sent zone 40, adjust the position of the circuit board 90, or flip the circuit board 90.

3A to 3D show four cases in which the first transfer unit 31 transfers a circuit board 90 from the feeding zone 10 to the (inspection platform 21 of the X-ray positioning device 20). In this embodiment, the back end processing device 50 is, for example, a drill target machine, and the processing control unit of the X-ray positioning device 20 can control the first transfer unit 31 according to the four situations of FIG. 3A to FIG. 3D. The board 90 performs different actuations to ensure that the subsequent feeding of the board 90 to the back end processing unit 50 is performed at the correct location.

In this embodiment, the circuit board 90 can include two positioning holes A1, A2 and a foolproof hole B. As shown in FIG. 3A to FIG. 3D, the positioning holes A1 and A2 are connected to the blind hole B. The line system forms a right-angled triangle. The X-ray positioning device 20 may first check the positions of the positioning holes A1 and A2, and then check the position of the positioning hole A1 and the anti-dwelling hole B; or, the positioning hole A1 and the anti-dwelling hole B may be inspected first. Position, and then check the positions of the positioning holes A1, A2 to appropriately adjust the position of the circuit board 90. The details will be described below.

The circuit board 90 shown in FIG. 3A is directed upward with the front side 901, and the positions of the positioning holes A1, A2 and the anti-scratch hole B are the transfer of the circuit board 90 to the rear end processing device 50 (for example: drilling The target machine can be processed directly in the correct position. That is, when the first transmitting unit 31 transmits the circuit board 90 from the feeding area 10 to the inspection platform 21 of the X-ray positioning device 20, a light (X-ray) is emitted through the light-emitting unit 23, and the image is emitted. When the recording unit 25 captures the sensing image formed by the circuit board 90 in the photosensitive range 22, as shown in FIG. 3A, the processing control unit controls the first transmitting unit 31 to directly transfer the circuit board 90 to the Waiting area 40.

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

The circuit board 90 shown in FIG. 3B has the front side 901 facing upward, and the positions of the positioning holes A1, A2 and the foolproof hole B are transmitted to the circuit board 90 to the rear end processing device 50 (for example: drilling The correct position at which the target machine can be processed differs by 180 degrees. Therefore, when the image capturing unit 25 captures the sensing image formed by the circuit board 90 in the photosensitive range 22 as shown in FIG. 3B, the processing control unit controls the first transmitting unit 31 to control the circuit board. 90 is rotated 180 degrees before being transferred to the to-be-sent zone 40.

In other embodiments, the processing control unit can control the first transmitting unit 31 to flip the circuit board 90 according to the sensing image.

The circuit board 90 shown in FIG. 3C has the back surface 902 facing upward. Since the X-ray positioning device 20 checks the positions of the positioning holes A1 and A2 and the positions of the positioning holes A1 and the foolproof holes B, the process control is performed. The unit can determine that the board 90 cannot be adjusted to the correct feed position anyway. Therefore, when the image capturing unit 25 captures the sensing image formed by the circuit board 90 in the photosensitive range 22 as shown in FIG. 3C, the processing control unit controls the first transmitting unit 31 to control the circuit board. The 90 is turned to the front side and then transferred to the waiting area 40.

The circuit board 90 shown in FIG. 3D also has the back surface 902 facing upward, but the positions of the positioning holes A1, A2 and the foolproof holes B are 180 degrees out of the position shown in FIG. 3C. Similarly, since the X-ray positioning device 20 checks the positions of the positioning holes A1 and A2 and the positions of the positioning holes A1 and the foolproof holes B, the processing control unit can determine that the circuit board 90 is rotated anyway. Unable to adjust to the correct feeding position. Therefore, when the image capturing unit 25 captures the sensing image formed by the circuit board 90 in the photosensitive range 22 as shown in FIG. 3D, the processing control unit controls the first transmitting unit 31 to control the circuit board. The 90 is turned to the front side, and the board 90 is rotated 180 degrees before being transferred to the to-be-sending area 40.

It is to be noted that although the foregoing embodiment has been described with the back end processing device 50 as a drill target machine, the present creation is not limited thereto. Any back end processing device 50 that needs to adjust the circuit board 90 to the correct feeding position to perform feeding can adjust the circuit board 90 through the X-ray positioning device 20 and the first transfer unit 31 in the front end operation. To the correct feeding position, I will not repeat them here.

For example, each of the second transfer units 32, 32' is a three-axis robot arm, and the first transfer unit 31 (six-axis robot arm) has the circuit board 90 according to the analysis result of the X-ray positioning device 20. Adjusted to a correct feeding position and sent to the waiting area 40, therefore, each of the second transfer units 32 (, 32') only needs to transfer the circuit board 90 located in the waiting area 40 to the corresponding back end processing. Subsequent processing of the board 90 can be performed by the device 50 (, 50').

In this embodiment, the circuit board 90 located in the to-be-sent area 40 is transmitted to the corresponding back-end processing device 50 (, 50') through each of the second transfer units 32 (, 32') instead of transmitting the same. The first transfer unit 31 directly transfers the circuit board 90 that has been adjusted to the correct position to the back end processing device 50 (, 50') in order to divide the devices in the circuit board feeding device 100 into a division. Efficiency processing.

For example, under such a division operation, since the first transfer unit 31 only has to work to adjust the circuit board 90 to a correct feed position, the circuit board 90 is transferred to the corresponding back end processing device. The operation of 50 is processed by the second transfer unit 32. When the first transfer unit 31 sends the circuit board 90 adjusted to the correct feed position to the to-be-sent area 40, the transfer can be continued (and adjusted). Another circuit board 91, at the same time, the circuit board 90 located in the to-be-sending area 40 is also synchronously sent by the second transfer unit 32 to a corresponding back-end processing device 50, and the back-end processing device 50 can Start the follow-up process.

During the subsequent processing by the backend processing device 50, the first transfer unit 31 can adjust the other chip board 91 to a correct feeding position and send it to the to-be-sending area 40, and then, by the second The transfer unit 32' sends the circuit board 91 located in the to-be-supplied area 40 to a corresponding back-end processing device 50'.

Similarly, the to-be-sending area 40 can also be divided into a plurality of sub-sending areas for placing corresponding different types of circuit boards. For example, the circuit boards 90 and 91 may be different types of circuit boards, and the corresponding rear end processing devices 50, 50' may be different processing machines, and the circuit boards 90 and 91 are respectively subjected to different subsequent processing. It should be noted that the number of the sub-feeding areas, the sub-to-be-sending areas, and the corresponding rear-end processing devices may be adjusted according to the type (number) of the circuit boards 90, 91, that is, in this embodiment, The circuit board feeding device 100 can process a plurality of different types of circuit boards at the same time, which can save manpower and time more effectively.
