Circuit board 90.
Fig. 3 A to Fig. 3 D are in one embodiment of the utility model, which feeds intake a circuit board 90 from this
Area 10 is sent to four kinds of situations of the X-ray positioning device 20 (on inspection platform 21).In the present embodiment, back-end processing device
50 be, for example, to bore target drone, which can control according to four kinds of situations of Fig. 3 A~Fig. 3 D
First transmission unit 31 carries out different starts to the circuit board 90, to ensure that the circuit board 90 is subsequently sent to the rear end
When processing unit 50, fed intake with correct position.
In the present embodiment, which may include two location holes A1, A2 and fool proof hole B, such as Fig. 3 A~Fig. 3 D institutes
Show, the online form right angle triangle of such location hole A1, A2 and fool proof hole B.The X-ray positioning device 20 can first check such
The position of location hole A1, A2 reexamine the position of location hole A1 and fool proof hole B；Alternatively, can first check location hole A1 with
The position of fool proof hole B, reexamines the position of such location hole A1, A2, to carry out tune appropriate to the position of the circuit board 90
It is whole.It will be described in more detail below.
901 upward with front, and the position of such location hole A1, A2 and fool proof hole B are circuit board 90 shown in Fig. 3 A
For by the circuit board 90 be sent to the back-end processing device 50 (such as：Bore target drone) correct position that can directly be handled.
It is exactly, when first transmission unit 31 puts down the inspection that the circuit board 90 is sent to the X-ray positioning device 20 from the material charging region 10
On platform 21, emit beam (X-ray) through the luminescence unit 23, and the image shoots with video-corder the circuit board 90 taken by unit 25 in the sense
When the sensing image formed in optical range 22 is as shown in Figure 3A, which controls first transmission unit 31 and directly will
The circuit board 90 is sent to the areas Dai Song 40.
In certain embodiments, which can control first transmission unit 31 rotation according to the sensing image
The circuit board 90.
Circuit board 90 shown in Fig. 3 B with front 901 upward, and the position of such location hole A1, A2 and fool proof hole B with
By the circuit board 90 be sent to the back-end processing device 50 (such as：Bore target drone) can be handled correct position difference 180 degree.
Therefore, when the image shoots with video-corder the circuit board 90 taken by unit 25 in the sensing image such as Fig. 3 B formed in the sensitive volume 22
When shown, which controls after the circuit board 90 first rotates 180 degree by first transmission unit 31, is resent to this
The areas Dai Song 40.
In other embodiments, which can control first transmission unit 31 overturning according to the sensing image
The circuit board 90.
Circuit board 90 shown in Fig. 3 C with the back side 902 upward, due to the X-ray positioning device 20 check such location hole A1,
The position of A2 and the position of location hole A1 and fool proof hole B, the processing and control element (PCE) can determine whether to rotate this anyway
Circuit board 90 can not all be adjusted to correct feeding position.Therefore, when the image shoots with video-corder the circuit board 90 taken by unit 25
When the sensing image formed in the sensitive volume 22 is as shown in Figure 3 C, which controls first transmission unit 31
It is front by the circuit board 90 overturning, is resent to the areas Dai Song 40.
Circuit board 90 shown in Fig. 3 D is similarly the back side 902 upward, but the position of such location hole A1, A2 and fool proof hole B
It sets and differs 180 degree with position shown in Fig. 3 C.Similarly, since the X-ray positioning device 20 checks the position of such location hole A1, A2
It sets and the position of location hole A1 and fool proof hole B, the processing and control element (PCE) can determine whether to rotate the circuit board anyway
90 can not all be adjusted to correct feeding position.Therefore, when the image shoots with video-corder the circuit board 90 taken by unit 25 in the sense
When the sensing image formed in optical range 22 is as shown in Figure 3D, which controls first transmission unit 31 by the electricity
The overturning of road plate 90 is front, then by after the circuit board 90 rotation 180 degree, is just sent to the areas Dai Song 40.
Although it should be noted that previous embodiment with the back-end processing device 50 be bore target drone illustrate, this practicality
It is novel to be not limited to this.It is any that circuit board 90 must be adjusted to the back-end processing dress that can just feed intake to correct feeding position
Set 50, all can in front operation by the X-ray positioning device 20 of the utility model and the first transmission unit 31 by the circuit
Plate 90 is adjusted to correct feeding position, does not add to repeat herein.
Fig. 4 is the top partial view diagram of the circuit board feeding apparatus 100 of one embodiment of the utility model.As shown in figure 4, the electricity
Road plate feeding apparatus 100 also include multiple second transmission units 32,32 ', in the present embodiment, respectively second transmission unit 32,
32 ' by the circuit board 90 for being located at the areas Dai Song 40 being sent to corresponding back-end processing device 50,50 '.
For example, respectively second transmission unit 32,32 ' is three axle robert arm, due to first transmission unit 31 (six
Shaft mechanical arm) circuit board 90 has been adjusted to correct feeding position simultaneously according to the analysis result of the X-ray positioning device 20
It send to the areas Dai Song 40, therefore, respectively second transmission unit 32 (, 32 ') need to will only be passed positioned at the circuit board 90 in the areas Dai Song 40
It send to corresponding back-end processing device 50 (, 50 '), subsequent processing can be carried out to the circuit board 90.
In the present embodiment, it will be passed positioned at the circuit board 90 in the areas Dai Song 40 by respectively second transmission unit 32 (, 32 ')
It send to corresponding back-end processing device 50 (, 50 '), rather than correct position will be adjusted to by first transmission unit 31
Circuit board 90 is conveyed directly to back-end processing device 50 (, 50 '), this is to make each dress in the circuit board feeding apparatus 100
It sets and divides the work, reach processing more efficiently.
For example, under such division of labor operation, due to first transmission unit, 31 need to bear the circuit board 90
It is adjusted to the work of correct feeding position, and the circuit board 90 is sent to the work of corresponding back-end processing device 50 by this
Second transmission unit 32 is handled, when first transmission unit 31 will be adjusted to the circuit board 90 of correct feeding position
