Referring to FIG. 1 , FIG. 3 to FIG. 6 , the following describes the execution process of the horizontal correction device 100 performing the horizontal correction on the circuit board 200 .

Referring to FIGS. 1 , 3 and 4 , firstly, the upright circuit board 200 can be transferred to the bottom side of the leveling device 100 by a device such as a robotic arm (not shown in the figure), and then The first clamping device 63 and the second clamping device 64 jointly clamp the top edge of the upright circuit board 200 . At this time, the first light emitting device 31 and the second light emitting device When the devices 41 are in operation, they emit light and are respectively received by the first light-receiving device 32 and the second light-receiving device 42, and the top edge of the circuit board 200 is lower than the first light-emitting device. 31 and the light emitted by the second light emitting device 41 , and the rotary drive unit 5 is in a state that has not been activated. In this state, since the circuit board 200 is not necessarily in a horizontal state when it is clamped by the first clamping device 63 and the second clamping device 64 , it is not suitable to directly perform subsequent processing procedures, so it must be The horizontal correction process is performed first.

Referring to FIG. 5 and FIG. 6 , when the horizontal calibration process of the circuit board 200 is to be performed, an instruction is issued by a control unit such as a control computer and a control chip not shown in the figure, so that the rotary drive unit 5 can be controlled to drive The rotating clamping mechanism 6 and the circuit board 200 rotate back and forth, and are respectively stored when the top edge of the circuit board 200 blocks the light emitted by the first light emitting device 31 and the second light emitting device 41 in stages. Corresponding rotation angle, the tilt state of the rotating clamping mechanism 6 is adjusted according to the rotation angle, so as to correct the horizontal state of the circuit board 200 .

Specifically, it is defined that the top edge of the circuit board 200 blocks the light emitted by the first light emitting device 31 as shown in FIG. 6 , so that the first light receiving device 32 does not receive the corresponding light. The rotation angle is the first rotation angle θ1, and defines the top edge of the circuit board 200 as shown in FIG. 5 to block the light emitted by the second light emitting device 41 so that the second light receiving device 42 does not receive the corresponding light. The rotation angle of the rotary drive unit 5 is the second rotation angle θ2. The adjustment of the tilted state of the rotation clamping mechanism 6 and the horizontal state of the circuit board 200 is performed by the rotation driving unit from the state where the rotation angle of the rotation clamping mechanism 6 is zero as shown in FIG. 4 . 5. Drive the rotating clamping mechanism 6 to incline to one side relative to the carrier structure 2. For example, in FIG. 5, the rotating driving unit 5 drives the rotating clamping mechanism 6 together with the circuit board 200 according to Rotate the drawing counterclockwise, so that the portion of the circuit board 200 corresponding to the second side 214 is gradually moved up and the portion corresponding to the first side 213 is gradually moved down until the portion of the circuit board 200 corresponding to the The top edge of the second side 214 just blocks the light emitted by the second light emitting device 41 . At this time, the second light receiving device 42 fails to receive the light emitted by the second light emitting device 41 , so the leveling device 100 determines the top edge of the circuit board 200 corresponding to the second side 214 The predetermined level has been reached, and the current rotation angle of the rotary drive unit 5 from zero (as shown in FIG. 4 ) to the state shown in FIG. 5 is stored as the second rotation angle θ2 (eg, 2 degrees). Subsequently, the rotation driving unit 5 drives the rotation clamping mechanism 6 to rotate in the reverse direction together with the circuit board 200 , for example, from the state of FIG. 5 to FIG. 6 to rotate clockwise in the drawing, so that the circuit The portion of the board 200 corresponding to the first side 213 is gradually moved upward and the portion corresponding to the second side 214 is gradually moved downward until the top edge of the circuit board 200 corresponding to the first side 213 is exactly as shown in FIG. 6 . Until the light emitted by the first light emitting device 31 is blocked, the first light receiving device 32 cannot receive the light emitted by the first light emitting device 31, so the level calibration device 100 determines that the The top edge of the circuit board 200 has reached a predetermined level, and the difference between the current rotation angle of the rotary drive unit 5 and the rotation angle of 0 in FIG. 4 is stored as the first rotation angle θ1 (for example, 6 degrees). According to the above-mentioned measurement of the first rotation angle θ1 and the second rotation angle θ2 , the subsequent horizontal state correction of the circuit board 200 can be performed, as described below.

In this embodiment, since the first board edge detection unit 3 and the second board edge detection unit 4 are symmetrically arranged on both sides of the rotary drive unit 5 , and the leveling device 100 is an overall The left and right are symmetrically configured, so according to the principle of geometric figures, the rotation angle θ3 required for the circuit board 200 to be corrected from the state of FIG. 4 to the horizontal state will be the difference between the first rotation angle θ1 and the second rotation angle θ2 Half of the absolute value of the difference, as shown in the following formula:

According to the horizontal state of the circuit board 200 , the side corresponding to the smaller of the first rotation angle θ1 and the second rotation angle θ2 measured by being rotated will be higher than the larger side. For example, in the foregoing example, the first rotation angle θ1 is 6 degrees and the second rotation angle θ2 is 2 degrees, which means that the circuit board 200 in FIG. 4 is not rotated. The top edge of the circuit board 200 corresponding to the second side 214 is higher than the top edge corresponding to the first side 213 , that is to say, in this example, the top edge of the circuit board 200 is in an unrotated and uncorrected state is a lower left-upper right sloping trend (not shown in the figure). Therefore, the rotation driving unit 5 can change the rotation clamping mechanism 6 from a state where the rotation angle is zero to correspond to the smaller of the first rotation angle θ1 and the second rotation angle θ2 (this In the example, the side with the smaller second rotation angle θ2 (that is, the side corresponding to the second side 214 ) rotates downward until the rotation angle reaches the first rotation angle θ1 and the second rotation angle θ2 The absolute value of the difference between the two is half of the absolute value (that is, θ3, which is 2 degrees in this example), that is, the horizontal correction of the circuit board 200 is completed, so that the circuit board 200 can be guaranteed to be in a horizontal state. Subsequent processing or shipping. Therefore, by using the light emitted by the first light emitting device 31 and the second light emitting device 41 as the height basis for leveling correction, the processing procedure of horizontally correcting the circuit board 200 is indeed fast, accurate and effective. When the light height of the first light emitting device 31 and the second light emitting device 41 needs to be adjusted, the carrier structure 2, the rotating clamping mechanism 6 and other structures can be suspended relative to the By pivoting the mechanism 1, the relative heights of the first light emitting device 31 and the second light emitting device 41 can be adjusted accordingly, so that the first light emitting device 31 and the second light emitting device 41 can be adjusted accordingly. The emitted light can be used as a height basis for horizontal correction.

It should be noted that, although the above description is to detect the second rotation angle θ2 first and then the first rotation angle θ1, it can also be adjusted to detect the first rotation angle θ1 first and then detect the first rotation angle θ1 as needed. Two rotation angles θ2, that is to say, different detection sequences can correctly complete the horizontal correction. In addition, in the aforementioned horizontal calibration process, after the rotation angle θ3 is known, the circuit board 200 is rotated downward from the side corresponding to the smaller of the first rotation angle θ1 and the second rotation angle θ2 , however, on the premise that the top edge of the circuit board 200 is in a straight line, it can also be set to compare the circuit board 200 with the corresponding first rotation angle θ1 and the second rotation angle θ2 One side of the larger one is rotated upwards.
