The circuit board transmission method of the present technical solution can prevent the distance between the circuit boards from being too small or too large, thereby facilitating the subsequent processes. [Embodiment] Hereinafter, a circuit board transmission system and a circuit board transmission method provided by the present technical solution will be further described in detail with reference to the accompanying drawings and embodiments. Referring to FIG. 1, a circuit board transmission system 10 provided by an embodiment of the present technical solution includes a first transmission device 11, a second transmission device 12, an induction device 13, and a controller 14. The first transfer device 11 and the second transfer device 12 are used to transfer a circuit board. The first transfer device 11 and the second transfer device 12 are disposed adjacent to each other along the board transfer side 200942107, so that the circuit board can be transferred from the first transfer device 11 to the second transfer device 12, and the circuit board is further transferred from the second The device 12 is transferred to a subsequent processing device, such as a Develeping/Etting/ Striping (DES) device. In the present embodiment, the first conveying device 11 includes a conveyor belt 111, a first driving wheel 112, a second driving wheel 113, and a first driving device 114. The first driving device 114 is connected to the first driving wheel 111 and the second driving wheel 112 by the conveyor belt 111 for driving the conveyor belt 111 to move and driving the first driving wheel 112 and the second driving wheel 113 to rotate. The first driving wheel 112 and the second driving wheel 113 are disposed on both sides of the first driving device 114 for extending the conveyor belt 111. The conveyor belt 111 is used to transport a circuit board placed thereon. Of course, the first transmitting device 11 can also be a structure of other transmittable circuit boards. The second conveyor 12 includes a plurality of transmission wheels 121 and at least one second drive unit 122. The plurality of transmission wheels 121 are sequentially arranged in the board conveying direction, and their axes are perpendicular to the board conveying direction. The second driving device 122 can be a motor, and the belt 123 is connected to the plurality of transmission wheels 121 to drive the plurality of transmission wheels 121 to rotate. The rotation of the plurality of transmission wheels 121 can transmit the circuit board placed thereon. . Of course, the second drive unit 122 can also be coupled to the drive wheel 121 by gears or other components. The distance between the first conveyor 11 and the second conveyor 12 should be less than one-half the length of one of the boards to prevent the board from falling during transport. For example, when the length of the board in actual production is 200 mm, the distance between the first conveyor 11 and the second conveyor 12 is preferably 15 to 80 mm. 9 200942107 The sensing device 13 includes a first sensor 131 for sensing the transfer position of the circuit board and a second sensor 132. The first sensor ι31 is disposed above the first conveyor 11 opposite to the conveyor belt 111, and the distance between the first inductor 131 and the conveyor belt 111 is within the sensing distance of the first inductor 131 to make the first The sensor 131 can effectively sense the transfer position of the circuit board on the conveyor belt in. The second sensor 132 is disposed above the second conveyor 12 opposite to the transmission wheel 121, and the distance between the second inductor 132 and the transmission wheel 121 is within the sensing distance of the second inductor 132, so that the second The sensor 132 can effectively sense the transfer position of the circuit board on the drive wheel 121. The first inductor 131 is disposed adjacent to the second inductor 132. The first inductor 131 is disposed above the conveyor belt 111 and adjacent to the second conveyor 12, and the second inductor 132 is disposed above the transmission wheel 121 and adjacent to the first conveyor 11. Thus, the sensing device 13 can sense the position of two adjacent circuit boards located at the first conveyor 11 and the second conveyor 12, respectively. The sensing distance between the first sensor 131 and the second sensor 132 may be determined as needed, and generally should be greater than or equal to the distance between the first transmitting device 11 and the second transmitting device 12 to facilitate subsequent adjustment of the board spacing. . When the distance between the first conveyor 11 and the second conveyor 12 is 15 to 80 mm, the distance between the first inductor 131 and the second inductor 132 is preferably 20 to 120 mm. The first inductor 131 and the second inductor 132 both have a sensing circuit inside, and each has a signal emitting port and a signal receiving port. The signal transmitting port is used for transmitting the sensing signal, and the signal receiving port is used for receiving the sensing signal reflected by the circuit board and transmitting the signal through the circuit board, and the sensing circuit receives the signal of the signal transmission port according to the signal receiving the 200942107 port. Transfer location. For example, when the circuit board is transferred to the lower side of the first sensor 131, the circuit board will start to reflect the sensing signal emitted by the signal transmitting port, so that the signal receiving port can change from receiving the sensing signal to receiving the sensing signal. Thereby, the sensing circuit of the first sensor 131 can send a message that the board has been sensed and transmitted to the controller 14. The sensing signal can be laser, infrared, ultrasonic or other signals. The controller 14 has a control circuit 141 and a timer circuit 142 therein. The timing circuit 142 is connected to the first sensor 131 and the second sensor ι32, and is used to obtain the sensing range of the second transmitting device 12 of the two adjacent circuit boards when the circuit board of the second transmitting device 12 leaves the second sensor 132. The time elapsed between the two adjacent circuit boards when the circuit board of the first transfer device n enters the sensing range of the first sensor 131. The control circuit 141 is electrically connected to the timing circuit 142, the first inductor 131, and the first driving device 114 for the time obtained by the timing circuit 142, the distance between the first sensor 131 and the second sensor 132, and The conveying speed of the second conveying device 12 controls the conveying speed of the conveying device 11, so that the two adjacent substrates located between the second conveying device 12 of the second conveying device are within a predetermined distance. Preferably, the controller 14 can be coupled to the sensing device 13 by a signal amplifier to ensure efficient transmission of the sensing results of the sensing device 13.

At this time, the transfer speed of the first transfer device 11_ is the same as the transfer speed of the second transfer device 12, and the transfer speed of the second transfer device 12 matches the processing speed of the subsequent processing station. The circuit board that is first transferred to the second transfer device 12 among any two adjacent circuit boards of the plurality of circuit boards is the second circuit board 21, and then the circuit board that is transferred to the second transfer device 12 is the nth +1 board 22. 〇 In the second step, the nth circuit board 21 is transferred to the second transmitting device 12, and after entering the sensing range of the second sensor 132, it leaves the sensing range of the second sensor 132. During this process, the signal receiving port of the second sensor 132 changes from the sensing signal that cannot be received by the signal transmitting port to the sensing signal, and then the sensing signal that can be received from the signal transmitting port. Until the sensor signal can not be received. When the nth circuit board 21 leaves the sensing range of the second inductor 132, the second sensor 132 transmits the message that the nth circuit board 21 leaves the second sensor 132 to the controller 14, so that the controller 14 Timing circuit 142 begins timing. 12 200942107 At this time, the n+1th circuit board 22 is still uploaded on the first transmitting device u, and does not enter the sensing range of the first sensor 131. The third step 'n+1th circuit board 22 is transmitted by the first transmitting device' and enters the sensing range of the first sensor 131. During this process, the ifl receiving port of the first sensor 131 changes from the undetectable number that cannot receive the signal transmitting port to receive the sensing signal. When the n+1th circuit board 22 enters the sensing range of the first sensor 131, the first sensor 131 transmits the message of the ❹n+1 circuit board 22 to the sensing range of the first sensor 131 to the control. The timer 14' causes the timing circuit 142 of the controller 14 to stop timing. At this time, the nth circuit board 21 has been transferred on the second transfer device 12 for a certain period of time. In the fourth step, the timing circuit 142 of the controller 14 acquires the sensing range from the nth circuit board 21 away from the second inductor 132 to the first sensor 131 to sense the n+1th circuit board 22 to enter the first sensor 131. The elapsed time of the sensing range, the control circuit 141 obtains the nth circuit board and the n+1 according to the time, the distance between the first sensor ι31 and the second inductor 132, and the transmission speed of the second transmitting device 12.

If S is greater than a predetermined distance c between the nth circuit board 21 and the η+ι circuit board 22, the controller 14 should appropriately increase the transmission speed VI of the first conveyor 11 so that the η+ι board The transfer speed of 22 is greater than the transfer speed of the nth circuit board 21. The transmission speed change value of the first transmitting device Λ is set to Λνι, that is, the changed first transmission device 11 transmits the transmission speeds V1, V1 + AV1 of the n+1th circuit board 22, and the transmitting device is configured to transmit the speed.
