[0060] It is worth noting that the complete method of using the automatic needle insertion machine and the automatic needle insertion system in this application is:

[0061] The first step is to adjust the positioning camera. First, turn on the LED light 16, select a reference object and place it in the material-taking tray 13 on the vibration chamber 15, adjust the exposure and clarity of the positioning camera 4 to a state where it can be clearly seen, and then put a frame reference object in the material-taking tray 13, adjust the position and direction of the camera by observing the range of projection, and adjust the position and direction of the positioning camera 4 so that the projection frame is parallel to the reference object;

[0062] The first phase circle 17 and the second phase circle 18 are arranged on the positioning camera 4, wherein the first phase circle 17 is arranged above the second phase circle 18, the first phase circle 17 is used to adjust the exposure of the positioning camera 4, and the second phase circle 18 is used to adjust the clarity of the positioning camera 4;

[0063] The frame reference object is selected in a manner of having a straight regular structure and being parallel to the frame of the vibration chamber 15 when placed horizontally.

[0064] The second step is to adjust the mechanical head. The first mechanical head 11 is a conical suction head, and the second mechanical head 12 is a flat mechanical head. Observe the first mechanical head 11 and the second mechanical head 12 from above to see whether the first mechanical head 11 shakes or tilts during the rotation. If there is no shaking, it means that the mechanical head is installed successfully. If shaking of the mechanical head is observed, the mechanical head needs to be adjusted until the mechanical head does not shake or tilt during the rotation. The first mechanical head 11 and the second mechanical head 12 are installed horizontally and the heights are kept consistent.

[0065] The third step is to adjust the material picking height and move the first mechanical head 11 to the center of the material picking tray 13. At this time, the coordinate position of the first mechanical head 11 is positioned by the first mechanical head positioning module 31. First, the processing center 2 issues a material picking instruction. The position of the motor Z axis 10 moves the first mechanical head 11 to the upper center of the material picking tray 13. The height of the motor Z axis 27 at this time is recorded as the material picking height H. After adjusting the material picking height H, the position coordinates (x1, y1, z1) of the first mechanical head 11 are saved. The height of Z1 is the material picking height H. Then the motor Z axis 27 is restored to return the motor Z axis 27 to the initial standby point (x0, y0, z0):

[0066] It should be noted that when adjusting the material picking height, a workpiece can be used for position testing to ensure that the material picking height of the motor Z axis 27 is maintained above the center of the material picking tray 13. When the material tray is replaced, the material picking height will change, and a height adjustment instruction needs to be issued to slowly lower the first mechanical head 11 to find a suitable height. After replacing a different mechanical head, the height of the first mechanical head 11 needs to be readjusted.

[0067] The fourth step is template learning. The template is set at the center position of the pin tray 6. The template is captured through the data processing unit 22 and the camera test unit 29. Modeling is performed through the processing center 2. After the modeling is saved, the modeling is applied to the processing center 2. The modeling is used for the position and action selection of the pin tray 6 of the pin insertion machine during automatic pin insertion and pin pressing. If there is a shadow in the captured image, it is necessary to frame the shadow-free area, test the image, select the shadow-free image for modeling and save it.

[0068] The fifth step is to set the camera calibration starting point and end point, enter the camera test unit 29, use the current position of the positioning camera 4 as the calibration starting point, then adjust the position of the positioning camera 4, compare the position of the positioning camera 4 with the position of the frame reference object in the first step, and adjust the coordinate position of the motor X-axis 8 and the motor Y-axis 9. By adjusting them to the appropriate position, the coordinates of the X, Y and Z axes can be calibrated as the starting point coordinates (x2, y2, z2) of the positioning camera 4. After completing the calibration of the starting position, the position of the positioning camera 4 is compared with the position of the frame reference, and the coordinate positions of the motor X-axis 8 and the motor Y-axis 9 are adjusted to above the pin disk 6 as the end point coordinate position of the positioning camera 4, and the coordinates of the adjusted motor X-axis 8, motor Y-axis 9 and motor Z-axis 10 are used as the end point coordinates (x3, y3, z3), and the starting point coordinates and the end point coordinates are respectively saved in the memory 23, and the shadow observation is scored, and the scoring rules are set to 1 to 100 points. The evaluation test is 90-100 for qualified calibration, and the starting point coordinates and the end point coordinates can be used.

[0069] Step 6: Set the starting point coordinates and the key point coordinates for the positions of the first mechanical head 11 and the second mechanical head 12. According to the Z-axis height determined in steps 1-5, the X-axis and Y-axis positions of the first mechanical head 11 and the second mechanical head 12 need to be calibrated. In this application, the four coordinates of the same axis need to be calibrated for the first mechanical head 11 and the second mechanical head 12 at the same height. First, move the first mechanical head 11 to the top of the center of the material picking tray 13, then move the positions of the X-axis and the Y-axis, measure the distance between the X-axis and the Y-axis through the first mechanical head positioning module 31, and when the camera test module displayed on the processing center 2 gives 90-100 points, a position is successfully calibrated. The scoring standard is: after setting the optimal distance, compare the difference between the optimal distance and the actual distance to obtain the evaluation strategy of different gears. In this application, four positions are calibrated for the first mechanical head 11 and the second mechanical head 12 respectively: the starting point coordinates of the first mechanical head 11 (x4, y4, z4), the end point coordinates of the first mechanical head 11 (x5, y5, z5), the starting point coordinates of the first mechanical head 11 for picking up materials (x6, y6, z6) and the end point coordinates of the first mechanical head 11 for inserting pins (x7, y7, z7), the starting point coordinates correspond to the position above the center of the material picking tray 13, and the end point coordinates correspond to the position above the center of the pin tray 6;

[0070] After the calibration of the starting point coordinates (x4, y4, z4) of the second mechanical head 12, the end point coordinates (x5, y5, z5) of the second mechanical head 12, the starting point coordinates (x6, y6, z6) of the second mechanical head 12 for material picking, and the end point coordinates (x7, y7, z7) of the second mechanical head 12 for pin insertion is completed, the mechanical head A and the mechanical head B are restored to the starting point coordinates.

[0071] It should be noted that if the height position of mechanical head B is inappropriate during the calibration process, origin compensation can be performed in the manufacturer's parameters. The origin compensation means comparing the height of mechanical head B with the calibrated height of mechanical head A to make the height of mechanical head B consistent with that of mechanical head A. After origin compensation, mechanical head B can be recalibrated.

[0072] The seventh step is to switch the working mechanical head, switching the conical mechanical head to a flat mechanical head. The flat mechanical head is used to limit the position of the workpiece needle. After the switch is completed, move the flat mechanical head to the previously calibrated material picking position. At this time, the flat mechanical head is placed above the center position of the vibration disk. Place a workpiece needle on the vibration disk, and place the flat mechanical head on the workpiece needle to keep it fit.

[0073] Step 8. Determine the residual material area, issue the residual material setting command, select the expected area and confirm to upload the area.

[0074] The ninth step is to set the material collection area. Two material collection areas are set, namely the first material collection area and the second material collection area. The two material collection areas are distinguished by color. The first material collection area and the second material collection area are both rectangular areas, and the left frame line of the first material collection area is smaller than that of the second material collection area. The first material collection area is the material collection range of mechanical head A, and the second material collection area is the material collection range of mechanical head B.

[0075] The tenth step is template setting. After setting the material picking area, enter the template setting module, put the workpiece needle into the material tray, perform a vibration test on the material tray, start the camera test system above the vibration tray, and open the template setting instruction. The template is used for the device to grab the workpiece needle in the correct position; then select the needle located in the center of the screen with a large gap around it, and adjust the size of the frame to keep the frame parallel to the workpiece needle; after starting the vibration disk, observe whether the position of the workpiece needle on the test panel is positive by observing the vibration disk camera. If the number of positive workpiece needles is greater than 80%, the template setting is completed, and the position and size parameters of the frame can be saved.

[0076] Step 11. Set the discharge position, issue the discharge position setting command for the mechanical head, move the mechanical head A to the discharge position, set the discharge height, move the motor Z-axis distance to adjust the height of the mechanical head A so that it just touches the discharge head, and save it as the discharge position coordinate.

[0077] Step 12. Set the material picking position, enter the material picking position setting instruction of mechanical head A, move the mechanical head to the material picking position, set the material picking height, adjust the height of the mechanical head by adjusting the height of the motor Z axis to make it close to the position above the discharge head, save the position after adjustment, and set the material picking position coordinates.

[0078] It should be noted that the coordinates of the material discharge position and the material collection position are both set on the mechanical head A, and the height of the mechanical head B is kept the same as that of the mechanical head A. If the heights are different, it is necessary to perform origin compensation on the mechanical head B so that the mechanical head B maintains the same height as the mechanical head A.

[0079] Step 13: Set the discharge point:

[0080] 1. Set the starting point A of the tray, move the mechanical head to the starting point of the pin tray, move the plus or minus of the Z axis to adjust the gripper height, and adjust the X-axis and Y-axis positions of the mechanical head A by moving the distance of the X-axis and Y-axis, so that the mechanical head A is located at the center of the tray discharge hole. After adjustment, save the current coordinate position, switch to the discharge height to save, and finally return the mechanical head A to the starting position.
