It should be noted that the automatic carrying mechanism 100 is mainly used for automatically feeding the PCB or automatically discharging the processed PCB. Of course, in other embodiments, the automatic handling mechanism 100 may also be used for performing automatic loading and unloading operations on other types of workpieces, and is not limited herein. The automatic transfer mechanism 100 may be applied to a processing system to transport a PCB board to a processing apparatus for processing, or to transport an already processed PCB board out of the processing apparatus. The processing system can be a drilling machine processing system and the like. For convenience of description, the following description will be mainly made on automatic feeding and discharging of the PCB.

An embodiment of the present invention provides an automatic conveying mechanism 100, and as shown in fig. 1, the automatic conveying mechanism 100 includes a material receiving assembly 1, a conveying assembly 2, a pressing assembly 3, and a material deciding assembly 4, and the material receiving assembly 1, the conveying assembly 2, the pressing assembly 3, and the material deciding assembly 4 are sequentially disposed.

As shown in fig. 1, the receiving assembly 1 is used for transferring an input workpiece to the conveying assembly 2 or receiving a workpiece output from the conveying assembly 2; specifically, in this embodiment, the workpiece may be a PCB, the PCB to be processed is placed on the material receiving assembly 1, and the material receiving assembly 1 transfers the PCB to the conveying assembly 2; or for receiving the finished PCB board output from the conveyor assembly 2.

As shown in fig. 1, the conveying assembly 2 is used for receiving a workpiece input by the material receiving assembly 1 and transferring the workpiece to the workbench 200, or transferring a workpiece output by the workbench 200 to the material receiving assembly 1; when the conveying component 2 conveys the workpiece to the workbench 200 or the workbench 200 conveys the workpiece to the conveying component 2, the pressing component 3 is used for pressing the workpiece and can be in rolling fit with the workpiece, namely the pressing component 3 can press the workpiece and simultaneously the contact surface between the pressing component 3 and the workpiece is in a rolling fit state; specifically, the pressing assembly 3 is specifically located above one end of the workbench 200 close to the conveying assembly 2, when a workpiece conveyed by the conveying assembly 2 contacts the workbench 200, at this time, the pressing assembly 3 presses down to press the workpiece onto the workbench 200, the workpiece continues to move towards the workbench 200 under the action of the conveying assembly 2, and as the pressing assembly 3 is in rolling fit with the workpiece, namely the pressing assembly 3 can be in rolling fit with the movement of the workpiece, the resistance of a rolling movement mode is smaller, and the obstruction of the movement of the workpiece can be reduced, the pressing assembly 3 can press the workpiece on one hand, and on the other hand, the obstruction of the workpiece on the movement towards the workbench 200 can be effectively avoided; similarly, when the processed workpiece is conveyed from the working table 200 to the conveying assembly 2, the workpiece is also pressed and positioned by the pressing assembly 3.

As shown in fig. 1, when the conveying element 2 conveys the workpiece to a predetermined position of the worktable 200 or the worktable 200 outputs the workpiece to the conveying element 2, the material-fixing element 4 extends out and abuts against the worktable 200 to prevent the workpiece on the worktable 200 from moving further. It should be noted that, in this embodiment, the material fixing assembly 4 is a telescopic cylinder; of course, other suitable devices capable of being raised and lowered may be used in other embodiments. It can be understood that, when loading a workpiece, after the operations of the aforementioned components are completed, the workpiece does not completely enter the working table 200, at this time, the working table 200 is moved forward, that is, the working table 200 moves a preset distance in a direction away from the conveying component 2, so as to separate the workpiece from the conveying component 2, then the material-fixing component 4 extends out and abuts against one end of the workpiece close to the conveying component 2, so as to block the workpiece from moving backward, then the working table 200 moves backward for a specified distance, at this time, the working table 200 and the workpiece generate a relative displacement, so as to completely enter the working table 200. When the machined workpiece is blanked, the workbench 200 moves backwards, that is, the workbench 200 moves towards the direction close to the conveying component 2, the material fixing component 4 extends out and abuts against one end of the workpiece far away from the conveying component 2, at the moment, the workbench 200 moves forwards, the material fixing component 4 blocks the workpiece to move forwards continuously, at the moment, the workbench 200 and the workpiece generate relative displacement, so that one end of the workpiece close to the conveying component 2 protrudes out of the workbench 200 gradually, and the workbench 200 moves backwards for a specified distance to transmit the workpiece to the conveying component 2.

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

In one embodiment, as shown in fig. 1 and fig. 2, the receiving assembly 1 includes a material bearing frame 11, a limiting structure 12 and a conveying structure 13, wherein the limiting structure 12 and the conveying structure 13 are both disposed on the material bearing frame 11, and the material bearing frame 11 is connected to the conveying assembly 2; specifically, in this embodiment, the material supporting frame 11 is a square frame for supporting a workpiece, such as a PCB.

As shown in fig. 2, the limiting structure 12 is used for forming a limiting track, and the end of the limiting track intersects with the conveying assembly 2; the conveying structure 13 is used for conveying the workpiece to move to the conveying assembly 2 along the limiting track; preferably, the extending direction of the connecting part of the material bearing frame 11 and the conveying component 2 is perpendicular to the extending direction of the limiting track, so that the PCB can be smoothly transferred to the conveying component 2 through the limiting track; understandably, the conventional PCB board is provided with positioning pins; in this embodiment, the PCB is loaded, the PCB is placed in the material bearing frame 11, the positioning pins of the PCB are clamped tightly in the limiting rails of the limiting structures 12, so as to position and fix the PCB, and the PCB can move along the fixed limiting rails, the PCB moves to the conveying assembly 2 along the limiting rails under the driving of the conveying structure 13, so as to prevent the PCB from shifting in the position switching process between the material receiving assembly 1 and the conveying assembly 2, so that the PCB can reach the conveying assembly 2 in a preset positioning state, and the pressing and positioning function of the pressing assembly 3 is matched, so that the PCB can be effectively prevented from shifting in the position from the material receiving assembly 1 to the workbench 200.

In some embodiments, as shown in fig. 2, the limiting structure 12 includes a moving assembly 121, a first limiting member 122 and a second limiting member 123; along the intersecting direction with the conveying direction of the conveying structure 13, the first limiting member 122 and the second limiting member 123 are arranged on the material bearing frame 11 in parallel, and the first limiting member 122 and/or the second limiting member 123 can move relative to the material bearing frame 11; the moving assembly 121 can drive the first limiting member 122 and/or the second limiting member 123 to move, so that the first limiting member 122 and the second limiting member 123 approach or separate from each other, and a limiting track can be formed when the first limiting member 122 and the second limiting member 123 approach each other. It can be understood that, when the moving assembly 121 drives at least one of the two limiting members to move so that the two limiting members approach each other, the two limiting members cooperate with the positioning pins capable of clamping the PCB, and form the limiting track, so that the PCB can be transferred from the receiving assembly 1 to the conveying assembly 2 along the limiting track; otherwise, in the same way, the moving assembly 121 drives at least one of the two limiting members to move so that the two limiting members are away from each other, so as to release the PCB board in the clamping state.

In some embodiments, as shown in fig. 2, two moving assemblies 121 are provided, wherein one moving assembly 121 drives the first limiting member 122 to move, and the other moving assembly 121 drives the second limiting member 123 to move. It can be understood that, by providing two moving assemblies 121 to control the first limiting member 122 and the second limiting member 123 respectively, the flexibility of state control of the first limiting member 122 and the second limiting member 123 can be improved.

In some embodiments, as shown in fig. 2, movement assembly 121 includes a push rod 1211, a telescoping device 1212, and a connector 1213; the push rod 1211 is positioned below the bearing surface of the material bearing frame 11, and the connecting piece 1213 is hinged on the push rod 1211; the retracting device 1212 is used to drive the push rod 1211 to retract in the conveying direction of the conveying structure 13. The first limiting member 122 and the second limiting member 123 both include a first clamping piece 1221 and a second clamping piece 1222, the first clamping piece 1221 of the first limiting member 122 and the second limiting member 123 is fixedly connected to the material bearing frame 11, the second clamping piece 1222 of the first limiting member 122 and the second limiting member 123 is disposed adjacent to and slidably disposed on the material bearing frame 11, and the first clamping piece 1221 and the second clamping piece 1222 of the first limiting member 122 and the second limiting member 123 are connected to the push rod 1211 through a connecting member 1213. As can be understood, since the first clamping pieces 1221 of the first limiting member 122 and the second limiting member 123 are fixed on the material receiving frame 11, and the second clamping pieces 1222 can slide relative to the material receiving frame 11, the telescopic device 1212 pushes the push rod 1211 to stretch along the conveying direction of the conveying structure 13, and drives the connecting piece 1213 to rotate relative to the push rod 1211, so as to push the second clamping pieces 1222 to slide along the material receiving frame 11, so that the second clamping pieces 1222 corresponding to the first limiting member 122 and the second clamping pieces 1222 corresponding to the second limiting member 123 can cooperate with each other to form the limiting track. In addition, since the first clamping piece 1221 is fixed relative to the material bearing frame 11, the position of the limiting track formed by the second clamping piece 1222 corresponding to the first limiting member 122 and the second clamping piece 1222 corresponding to the second limiting member 123 is fixed, and the positioning accuracy of the PCB board can be further improved. It should be noted that, in this embodiment, the second clamping piece 1222 includes a clamping body and a bearing, and the clamping body is slidably sleeved on the material holding frame 11 through the bearing.

It should be noted that, in this embodiment, the rotation driving device 14 may be specifically a telescopic cylinder; of course, in other embodiments, the rotation driving device 14 may be other devices capable of extending and retracting. It can be understood that, the material loading frame 11 is driven to rotate by the rotation driving device 14 so that one end of the material loading frame 11 away from the conveying assembly 2 abuts against the ground or the working surface to form a material loading passage, so as to place the PCB board on the material loading frame 11 for loading, and then the rotation driving device 14 drives the material loading frame 11 to rotate so as to raise the material loading frame 11 to a position parallel to the working surface of the conveying assembly 2, so as to transfer the PCB board to the conveying assembly 2 through the conveying structure 13. Consequently, hold work or material rest 11 to rotate to connect in conveyor components 2 through the setting to make and connect material subassembly 1 can change position state according to actual conditions, be convenient for carry out PCB board material loading and PCB board transmission. Of course, in other embodiments, the receiving assembly 1 may also include a frame, the material holding frame 11, the limiting structure 12 and the conveying structure 13 are all disposed on the frame, and the material holding frame 11 is rotatably connected to the frame.

Understandably, when conveying assembly 2 carries PCB board to base or base and carries PCB board to conveying assembly 2's in-process, compress tightly 32 through the drive of first elevating gear 31 and be close to workstation 200, drive and compress tightly the PCB board that the rolling member 33 butt that 32 is connected removed on workstation 200, rolling member 33 can compress tightly the PCB board, and can follow the PCB board and remove and carry out the retinue roll, can avoid causing the hindrance to the removal of PCB board.

In some embodiments, as shown in fig. 8, the rolling member 33 includes a roller (not shown), a rolling driving device 331, and a belt 332, the roller is rotatably disposed on the pressing member 32, the belt 332 is tensioned on the pressing member 32 by the roller, the rolling driving device 331 is configured to drive the roller to rotate, and the belt 332 is driven to rotate by the roller, so that the belt 332 can follow the movement of the workpiece to be synchronously driven.

In some embodiments, as shown in fig. 5, the conveying assembly 2 includes a first conveying member 21 and a second conveying member 22 which are arranged in a stacked manner, and the first conveying member 21 and the second conveying member 22 can alternately abut against the receiving assembly 1 and the workbench 200; when the material receiving assembly 1 receives an input workpiece, the first conveying piece 21 abuts against the material receiving assembly 1 and the workbench 200, receives the workpiece input from the material receiving assembly 1 and transfers the workpiece to the workbench 200; when the workbench 200 outputs the workpiece, the second conveying member 22 abuts against the workbench 200 and the material receiving assembly 1, receives the workpiece output from the workbench 200, and transfers the workpiece to the material receiving assembly 1.
