Alternatively, a laser direct imaging technology is used. The laser direct imaging technology directly images the image on the circuit board by laser scanning, and the image is more fine.

[0037] The first lifting suction and lifting assembly 4 includes a linear module 41 and a suction platform 42, the upper end of the linear module 41 is provided with a sliding table 43, the linear module 41 is vertically fixed on the sliding table 43, and the sliding table 43 is slidingly connected with the horizontal slide rail 6.

The second lifting suction and lifting assembly 5 includes a linear module 41 and a suction platform 42, and the upper end of the linear module 41 in the second lifting suction and lifting assembly 5 is also connected with a sliding table 43. The sliding table 43 in the second lifting suction and lifting assembly 5 is connected with the sliding table 43 in the first lifting suction and lifting assembly 4 and the two driving belts 73 one by one respectively.

[0038] The suction platform 42 includes a cross beam 421 and a longitudinal beam 422 arranged on the cross beam 421, the longitudinal beam 422 is arranged vertically with the cross beam 421, and the longitudinal beam 422 is arranged at least two along the length direction of the cross beam 421, and can be arranged three or four at intervals. The cross beam 421 is fixed with the moving part of the linear module 41, and a plurality of suction nozzles 423 are installed on the longitudinal beam 422. The suction nozzle 423 is connected with a suction device, so that after the suction nozzle 423 contacts with the surface of the circuit board 3, the circuit board 3 is sucked through the suction device, and the suction nozzles 423 are arranged at intervals along the length direction of the longitudinal beam 422. A vibration assembly 8 is further arranged on the suction platform 42 of the first lifting suction and lifting assembly 4, and the vibration assembly 8 is used to vibrate after the circuit board 3 is lifted by the suction platform 42. When two or more circuit boards 3 are connected due to suction or adhesion, the lower circuit board 3 is separated through the vibration assembly 8, so that only one circuit board 3 is moved to the exposure position each time.

[0039] Reference Figure 5The suction nozzle 423 comprises a fixing frame 4231, an intermediate rod 4232, a spring 4233 and a rubber head 4234.

The vibration assembly 8 is arranged on the longitudinal beam 422 close to the end of the cross beam 421. When the vibration assembly 8 vibrates the circuit board 3, one side of the circuit board 3 can be vibrated more greatly, so that the adhered circuit board 3 is more easily separated.

[0040] Reference Figure 6 The correction assembly 9 is arranged on the side of the feeding platform 13 close to the exposure position. The circuit board 3 that falls due to adhesion during the suction process cannot be accurately positioned and may be deviated in position. Directly placing the circuit board 3 to the exposure position may cause the exposed circuit to exceed the edge of the circuit board 3 due to excessive deviation. The correction assembly 9 is used to position the circuit board 3, so that the position of the circuit board 3 sucked by the first lifting suction and hoisting assembly 4 from the correction assembly 9 is relatively accurate each time. The correction assembly 9 comprises a horizontal plate 91, a first pushing frame 92 and a second pushing frame 93. The first pushing frame 92 and the second pushing frame 93 are respectively arranged on two sides of the horizontal plate 91 perpendicular to each other. Driving members 94 are connected on the first pushing frame 92 and the second pushing frame 93. The driving members 94 can be selected as electric cylinders, pneumatic cylinders or hydraulic cylinders. The driving members 94 drive the first pushing frame 92 and the second pushing frame 93 to move in the direction perpendicular to the side of the horizontal plate 91 corresponding to each other. When the first pushing frame 92 and the second pushing frame 93 are at the movement end point, the first pushing frame 92 and the second pushing frame 93 right the deviated circuit board 3. A plurality of air holes 95 are arranged on the horizontal plate 91 close to the first pushing frame 92 and the second pushing frame 93. The air holes 95 are connected to the air suction device below. When the circuit board 3 is placed on the horizontal plate 91, the air holes 95 can make the resistance of the circuit board 3 to the upper surface of the horizontal plate 91 greater. During the movement of the first pushing frame 92 and the second pushing frame 93 to the circuit board 3, the movement of the circuit board 3 due to the inertial force is reduced, so as to ensure the accuracy of the position of the circuit board 3 after movement.

[0041] Reference Figure 3 And Figure 7 The thickness detection sensor 10 is further arranged above the correction assembly 9, and the thickness detection sensor 10 is connected with a moving piece 101, the moving piece 101 is an electric cylinder, a pneumatic cylinder or a hydraulic cylinder, the moving direction of the moving piece 101 is horizontally arranged, and the thickness detection sensor 10 is installed at the moving part of the moving piece 101, the moving piece 101 is fixed on the rack 1, when the circuit board 3 that is corrected by the correction assembly 9 is sucked by the first lifting suction and hoisting assembly 4 again, and is lifted to the position with the same height as the thickness detection sensor 10, the moving piece 101 moves the thickness detection sensor 10 to the position of the circuit board 3, and the distance detection is performed at the upper and lower positions, so that the thickness detection of the circuit board 3 is completed, when the thickness is greater than that of one circuit board 3, the movement of the vibration assembly 8 cannot separate the over-sucked circuit board 3, so that the next exposure is completed, the circuit board 3 sucked at this time needs to be directly moved to the position of the discharging platform 14 by the first lifting suction and hoisting assembly 4, and the circuit board 3 placed by the first lifting suction and hoisting assembly 4 is staggered with the circuit board 3 placed by the second lifting suction and hoisting assembly 5 at the discharging platform 14, when the staff takes out the circuit board 3 from the position of the discharging platform 14, the circuit board 3 placed by the first lifting suction and hoisting assembly 4 can be distinguished in time.

[0042] The working process of the embodiment is as follows:

[0043] Firstly, the staff places a plurality of stacked circuit boards 3 at the position of the discharging platform 13, and then the first lifting suction and hoisting assembly 4 sucks the circuit boards 3 from top to bottom in turn, when one circuit board 3 is sucked and the lifting distance is 2-5 cm from the next circuit board 3, the vibration assembly 8 vibrates the sucked circuit board 3, so that part of the over-sucked circuit board 3 falls off, and then the circuit board 3 is placed at the position of the correction assembly 9 to correct the position of the circuit board 3, and then the first lifting suction and hoisting assembly 4 sucks again and reaches the position of the thickness detection sensor 10, and then the thickness detection sensor 10 confirms the number of the sucked circuit boards 3, the number of the circuit boards 3 with appropriate thickness is one, the first lifting suction and hoisting assembly 4 horizontally moves and places the circuit board 3 at the exposure position, the number of the circuit boards 3 with excessive thickness is more than one, and the first lifting suction and hoisting assembly 4 directly places the circuit boards 3 on the discharging platform 14 for the staff to take out and adjust, the exposed circuit board 3 is sucked and placed on the discharging platform 14 by the second lifting suction and hoisting assembly 5, and the circuit boards 3 placed by the first lifting suction and hoisting assembly 4 and the second lifting suction and hoisting assembly 5 are staggered at the discharging platform 14, so as to be distinguished.
