The conventional marking method is laser engraving or ink jet, but because there may be some small differences in the specifications or quality of each batch of circuit boards, such as solder mask color, thickness, surface treatment status of bonding pads, etc., before regular marking, marking parameters at least including marking position, pattern, size and number, etc., are required to be adjusted and tested to achieve the required visibility and readability, and in addition, the operation parameters of marking equipment such as laser engraving machine and ink jet equipment, such as laser energy, frequency, ink jet amount and speed, etc., must be adjusted relatively.
The common drawing and recording system is a single-functional device for drawing a pattern at a set position on the circuit board, and after the drawing and recording operation, the circuit board is taken down and moved to other auxiliary observation devices (such as a microscope) to confirm whether the requirement specification of a customer is met. If the user does not accord with the preset operation, the user needs to move back to the equipment, the operation parameters are adjusted again, and the drawing operation is carried out again. This type of operation is generally referred to as off-line evaluation of operational parameters, which is cumbersome and time-consuming. In addition, the photographing unit of the drawing and recording system is not the same as the auxiliary observation device, which may cause different image capturing parameters and display different images, resulting in erroneous judgment of the operator.

The control unit 21 is electrically connected to each component, and is responsible for the operation of the whole system, and is a computer host or a computer control system.
The carrier unit 22 is a working machine, and includes an electric transfer platform 221, and the electric transfer platform 221 is a moving mechanism controlled by an electromechanical device, and can move accurately in the horizontal direction. A fixture 222 may be further installed on the electric transfer platform 221, and the fixture 222 fixes the position of the circuit board 30 to be drawn.

The drawing unit 24 is disposed above the stage unit 22, and is used for drawing a corresponding pattern at a drawing position of the circuit board 30, and the drawing unit 24 is a laser engraving machine or an ink jet device. In the embodiment, the laser engraving machine emits the set energy to form the drawing pattern on the circuit board 30. If the equipment is an ink-jet equipment, the ink-jet drawing mode is adopted for operation. The marking unit 24 has a mechanism for fine adjustment or movement of position according to different devices. The drawing and marking graph comprises at least one of a two-dimensional bar code, a QR code, characters or a mark symbol and the like.
The optical reading unit 25 is disposed above the stage unit 22, and is used for photographing the circuit board 30. The optical reading unit 25 is a digital camera or a digital video camera in the present embodiment. The optical reading unit 25 is connected to the control unit 21 and outputs the captured image. In the present embodiment, the optical reading unit 25 mainly takes pictures of the circuit board before and after the drawing, and is defined as a first circuit board image and a second circuit board image respectively. The relative positions of the stage unit 22, the marking unit 24 and the optical image capturing unit 25 are fixed after being calibrated and positioned, so that the electric transfer platform 221 can accurately move the circuit board 30 to the correct position for photographing and marking.
The display unit 26 is a display in this embodiment, and is used for displaying the circuit board image captured by the optical reading unit 25, and forming a drawing pattern on the second circuit board image in a semitransparent overlapping manner.
Next, the description will be made of the drawing and writing system of the present invention, in conjunction with the operation method of the present invention:
in step 101, an image of the circuit board without the pre-drawing picture is obtained and defined as a first circuit board image; firstly, the circuit board 30 is placed on the electric transfer platform 221 of the stage unit 22, the jig 222 is used to fix the circuit board 30, and then the electric transfer platform 221 carries the circuit board 30 to move to the lower side of the optical image capturing unit 25; the optical image capturing unit 25 captures the circuit board 30, the display unit 26 displays the circuit board image, and the circuit board image is defined as a first circuit board image 40 (as shown in fig. 3), in the embodiment of fig. 3, two first circuit board images 40 are obtained by performing two circuit board 30 drawing operations at a time.
Step 102, setting drawing and recording operation parameters of the drawing and recording graph. The input unit 23 inputs the related drawing operation parameters such as the drawing position, the drawing pattern, the size and the number according to the selection content of the operator, and as shown in fig. 4, the drawing pattern 52 is set at the drawing position 51 of each of the first circuit board images 40. Since the marking unit 24 is a laser engraving machine, the adjustment of the focal length, energy, frequency, etc. of the laser is also included. The ink jet device includes ink jet color, position, and the like.
And 103, executing the drawing and recording operation according to the drawing and recording position. At this time, the electric transfer platform 221 drives the circuit board 30 to move to a position below the drawing unit 24, and the drawing unit 24 draws the drawing pattern 52 at the drawing position 51 of the circuit board 30.
Step 104, the printed circuit board image is obtained and defined as the second circuit board image. The electric transfer platform 221 moves the circuit board 30 to the lower side of the optical image capturing unit 25 again, captures the circuit board 30 after drawing the drawing pattern 52, the control unit 21 defines the received image as a second circuit board image 60 (as shown in fig. 5), the second circuit board image 60 has at least one drawing image 62 therein, and the drawing image 62 is the drawing pattern captured after drawing.
The control unit 21 then causes the drawing pattern 52 (shown by a dotted line) to be displayed on the second circuit board image 60 in a semi-transparent overlay manner via the display unit 26 (as shown in fig. 6). In practice, if the setting is correct, the marking pattern 52 will completely overlap the marking image 62, and for illustration, it is assumed that the input setting is wrong, so that the marking pattern 52 is clearly separated from the marking image 62. Thus, the operator can judge whether the drawing standard including the drawing position, the drawing, the size and the like meets the requirement according to the content displayed by the display unit 26, if yes, the operator finishes the work and performs the drawing operation of other circuit boards, and if not, the operator adjusts the drawing operation parameters through the input unit 23 and performs the drawing evaluation operation again to obtain the optimal operation parameters. Although only one drawing pattern is formed on the circuit board 30 in this embodiment, in practice, a plurality of drawing patterns may be formed on the circuit board at a time, each of which is set to a slightly different drawing operation parameter, and an optimum operation parameter is selected according to the result, which is advantageous for shortening the evaluation time.
In summary, the embodiment of the present invention provides a drawing and recording system and an operation method thereof with online evaluation, wherein an operator can perform the drawing and recording operation and evaluate and adjust the parameters of the drawing and recording operation without removing the circuit board from the machine, i.e. the circuit board does not need to be taken down and moved to other observation devices, thereby greatly shortening the time of the drawing and recording evaluation operation.
