Detailed implementation manners
[0020] Combined with Figures 1 to 5 As shown, this embodiment provides an upper plate mechanism, and the upper plate mechanism includes: a liftable shuttle assembly 11, a lifting and transverse reciprocating feeding mechanism 16, a board taking mechanism 12, a liftable workbench 13, a manipulator gripper 14, an unloading conveying mechanism 15, and a roller conveying mechanism 17; the unloading conveying mechanism 15 is arranged between the liftable workbench 13 and the lifting and transverse reciprocating feeding mechanism 16, and the lifting and transverse reciprocating feeding mechanism 16 is arranged between the roller conveying mechanism 17 and the unloading conveying mechanism 15. The liftable shuttle assembly 11 is used for storing the substrate A, and the board taking mechanism 12 is adapted to take out the substrate A in the liftable shuttle assembly 11 one by one and transport it onto the liftable workbench 13; the manipulator gripper 14 is arranged on the liftable workbench 13 to transport the substrate A to the printing mechanism, at this time the board taking mechanism 12 gives way to transport the substrate A back onto the liftable workbench 13 after printing; then, the liftable workbench 13 descends to make the substrate A fall on the unloading conveying mechanism 15, and the lifting and transverse reciprocating feeding mechanism 16 transports the substrate A on the unloading conveying mechanism 15 one by one to the roller conveying mechanism 17 for arrangement, and the roller conveying mechanism 17 is adapted to synchronously convey several substrates A to the next working station.
[0021] In this embodiment, the upper plate mechanism includes a frame, and the lifting shuttle 111 assembly, the lifting and transverse reciprocating feeding mechanism 16, the plate taking mechanism 12, the liftable workbench 13, the manipulator gripper 14, and the roller conveyor mechanism 17 are respectively arranged on the frame.
[0022] Combined with Figures 1 to 2 As shown, the liftable shuttle assembly 11 includes a shuttle 111 and an equidistant lifting mechanism 112 connected to the shuttle 111. Multiple placement slots 1111 suitable for placing the substrate A are arranged on the opposite inner sides of the shuttle 111. For example, 30 - 60 placement slots 1111 are provided, and the height of each placement slot 1111 is greater than the thickness of the substrate A. The equidistant lifting mechanism 112 is suitable for driving the shuttle 111 to rise and fall to cooperate with the plate taking mechanism 12 to take out the substrate A one by one to the liftable workbench 13. Specifically, the plate taking mechanism 12 is provided with a driving device for driving its movement on the frame. Two claw arms 121 suitable for inserting between adjacent placement slots 1111 are arranged on the plate taking mechanism 12. During operation, the shuttle 111 rises by one substrate position under the drive of the equidistant lifting mechanism 112, and then the plate taking mechanism 12 is inserted below the corresponding substrate A. At this time, the equidistant lifting mechanism 112 descends by a fixed displacement, so that the substrate A falls onto the claw arms 121 of the plate taking mechanism 12, and then the plate taking mechanism 12 is driven to withdraw from the shuttle 111 and move to the liftable workbench 13. The equidistant lifting mechanism 112 in this embodiment can adopt a nut and screw structure, which is convenient for accurately controlling the lifting height.
[0023] A full shuttle storage position 113 is arranged on one side of the liftable shuttle assembly 11 away from the liftable workbench 13, and an empty shuttle storage position 114 is arranged above the full shuttle storage position 113. The full shuttle storage position 113 is provided with a moving mechanism to convey the shuttle 111 with the substrate A to the loading position; the liftable shuttle assembly 11 is suitable for conveying the empty shuttle 111 to the empty shuttle storage position 114 for storage after all the substrate A is taken out through the equidistant lifting mechanism 112. By setting the full shuttle storage position 113 and the empty shuttle storage position 114 here, automatic feeding and automatic unloading of the shuttle 111 can be realized, reducing the workload of the operator.
[0024] Combined with Figures 1 to 3As shown, the liftable workbench 13 includes a lifting device 131 and a lifting plate 132. The lifting plate 132 is adapted to be lifted under the drive of the lifting device 131 to pass through the board taking mechanism 12 and lift the substrate A on the board taking mechanism 12 until it is separated from the board taking mechanism 12. Here, the lifting device 131 can be a lifting motor, a lifting cylinder, etc. A claw arm 121 avoidance position is provided on the lifting plate 132, so that when the lifting plate 132 rises, it will not be affected by the board taking mechanism 12. The substrate A is supported by the rising of the lifting plate 132 to transfer the substrate A from the board taking mechanism 12 to the lifting plate 132. Above the lifting plate 132, a manipulator gripper 14 installed on the frame is provided. The manipulator gripper 14 is adapted to extend under the substrate A to lift the substrate A, and the manipulator gripper 14 is adapted to move to the printing station to print the substrate A and send the substrate A back to the lifting plate 132 after printing. Here, the manipulator gripper 14 acts on the edge position of the lower surface of the substrate A and lifts the substrate A from the lifting plate 132 by lifting; the manipulator gripper 14 includes a double-arm cylinder 141 and grippers 142 respectively connected to the double-arm cylinder 141. The double-arm cylinder 141 is used to drive the grippers 142 to perform opening and closing actions to clamp and release the substrate A. It should be noted that the manipulator gripper 14 is self-equipped with a positioning mechanism to facilitate the correction of the substrate A during grasping. The gripper 142 is provided with a step portion adapted to support the substrate A, so as to prevent damage to the substrate A. After the substrate A is printed and sent back to the lifting plate 132, the lifting device 131 drives the lifting plate 132 to descend so that the substrate A falls back onto the unloading conveying mechanism 15. The unloading conveying mechanism 15 is provided with a transmission roller structure for conveying the substrate A to the lifting and traversing reciprocating feeding mechanism 16.
[0025] In a preferred embodiment, a positioning device 143 is provided on the side of the liftable workbench 13. The positioning device 143 includes baffles and cylinders provided on both sides of the lifting plate 132. The cylinders are adapted to drive the baffles to move towards the substrate A to position both sides of the substrate A. The positioning device 143 can prevent the substrate A from skewing.
[0026] Combined with Figure 4As shown, the lifting and transverse reciprocating feeding mechanism 16 includes a telescopic device 161, a supporting plate 162 and a lifter 163. The two supporting plates 162 are arranged on the telescopic device 161. The lifter 163 is suitable for driving the telescopic device 161 and the supporting plates 162 to rise or fall synchronously. The telescopic device 161 is suitable for driving the supporting plates 162 to move back and forth between the liftable workbench 13 and the roller conveyor mechanism 17 to transport the substrates A one by one from the liftable workbench 13 to the roller conveyor mechanism 17 and arrange them on the roller conveyor mechanism 17. During operation, the lifter 163 is first in a descending state, and the telescopic device 161 drives the support plate 162 to move one substrate position toward the direction of the unloading conveying mechanism 15, and then the lifter 163 drives the telescopic device 161 and the support plate 162 to rise to lift one substrate A of the unloading conveying mechanism 15, and after lifting, the telescopic device 161 is controlled to retract one substrate position to bring the substrate A back to the roller conveying mechanism 17. Since the support plate 162 only moves one substrate position each time, the substrate A can be gradually moved from the position of the unloading conveying mechanism 15 to the roller conveying mechanism 17. When the roller conveying device is full of substrates A, all substrates A can be synchronously transferred to the next station at one time through the roller conveying mechanism 17. There is no need to interrupt the whole process, and the output is high.
[0027] In this embodiment, the process surface of the product will not be touched during transportation, so that the subsequent photoresist coating, printing, etching and other process effects will not be affected, and the product quality is higher. The entire board loading process has a high degree of automation, which can effectively reduce the workload of the operator.

All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
[0029] The above description of the drawings used in the implementation manner only shows certain embodiments of the utility model and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying creative work.
