[0033] Specifically, the PCB plate turnover module 4 is further fixedly provided with a sliding block matched with the conveying guide rail 1 below, and the height adjusting telescopic rod 41 is further arranged below the driven plate 42, the output shaft of the height adjusting telescopic rod 41 is connected with the driven plate 42 and adjusts the height of the driven plate 42; in this embodiment, the height adjusting telescopic rod 41 is more convenient for the vacuum suction plate 45 to operate and adsorb the workpiece, and can more easily release the workpiece from the receiving surface.

In this embodiment, the position of the vacuum suction cup 55 can be adjusted more precisely through the lifting assembly.

[0038] The working principle and usage process of this utility model: In the process of using this technical solution, the staff places the workpiece to be transferred and transported, i.e., the PCB board, on the PCB board positioning module 3. At this time, the workpiece is placed on the upper surface of the lifting plate 38. The lifting plate 38 is connected to the external negative pressure vacuum pump through a gas delivery hose. When the workpiece is placed on the lifting plate 38, the negative pressure vacuum pump is activated to draw the gas from the upper surface of the lifting plate 38. Under the action of the negative pressure vacuum pump, the gas is drawn from the negative pressure hole 39. At this time, the workpiece on the upper surface of the lifting plate 38 will remain stable under the action of negative pressure.

[0039] At the bottom of the lifting plate 38, a first positioning component 34 and a second positioning component 35 are also provided. The first positioning component 34 and the second positioning component 35 are used to adjust the position of the lifting plate 38 on the X-axis and Y-axis of the horizontal plane. The first positioning component 34 and the second positioning component 35 are perpendicular to each other on the horizontal plane, and their structures are consistent.

[0040] During operation, the telescopic push rod 36 uses its own thrust to move its telescopic rod, thereby causing the positioning push plate 37 installed on its telescopic rod to adjust its position synchronously on the horizontal plane. At this time, the two positioning push plates 37 installed on the first positioning component 34 and the second positioning component 35 are displaced in the X and Y axes of the horizontal plane. The positioning push plates 37 then push the lifting plate 38 to displace in the X and Y axes of the horizontal plane, which facilitates the precise position adjustment of the lifting plate 38 during the placement and removal of the workpiece. This implementation method allows workpieces of any size to be placed on the lifting plate 38 without the need to use clamps to hold and fix the workpiece.

[0041] The first servo motor 32 can rotate in the horizontal direction, and in turn synchronously drive the support plate 33 to rotate, and in the process, the first positioning assembly 34, the second positioning assembly 35 and the lifting plate 38 above the support plate 33 can be synchronously adjusted in angle;

[0042] The PCB positioning module 3 synchronously adjusts the positions of various components above the PCB positioning module 3 when sliding on the conveying guide rail 1, so as to convey the workpiece placed above the PCB positioning module 3 along the setting direction of the conveying guide rail 1;

[0043] When the PCB positioning module 3 is transferred to a suitable position and the workpiece on the lifting plate 38 needs to be transferred, the negative pressure vacuum pump connected to the lifting plate 38 stops running, and at this time, the workpiece will not be tightly attached to the lifting plate 38 under the action of negative pressure;

[0044] The angle adjusting motor 43 is powered to rotate the output shaft thereof, and in turn drive the deflection arm 44 to deflect. The deflection arm 44 can be deflected by 180° under the action of the angle adjusting motor 43. The upper surface of the vacuum suction plate 45 is also uniformly provided with negative pressure holes, and the vacuum suction plate 45 is deflected to tightly attach to the upper surface of the workpiece on the upper surface of the lifting plate 38 under the action of the angle adjusting motor 43. At this time, the negative pressure vacuum pump extracts the vacuum of the vacuum suction plate 45, so that the workpiece on the upper surface of the lifting plate 38 is adsorbed to the upper surface of the vacuum suction plate 45 under the action of negative pressure. Then, the angle adjusting motor 43 drives the deflection arm 44 to rotate reversely by 180°. At this time, the workpiece is deflected under the action of the vacuum suction plate 45 and is adsorbed to the upper surface of the vacuum suction plate 45. At this time, the workpiece is deflected and can be processed on the upper surface by an external device;

[0045] After being processed, the PCB turnover module 4 slides on the conveying guide rail 1 and conveys the workpiece along the setting direction of the conveying guide rail 1 to the PCB fixing module 5;

[0046] During the operation of the PCB turnover module 4, the height adjusting telescopic rod 41 is further arranged in the PCB turnover module 4. When the height adjusting telescopic rod 41 operates, the height of the driven plate 42 is changed by pushing the telescopic end of the height adjusting telescopic rod 41, so as to be compatible with workpieces of different thickness specifications, and the vacuum suction plate 45 can be kept parallel to the lifting plate 38 when being deflected to the top end of the lifting plate 38;

[0047] When the PCB plate circulation module 4 is conveyed to the side of the PCB plate fixing module 5, the workpiece placed on the PCB plate circulation module 4 needs to be transferred to the PCB plate fixing module 5 for processing, at this time, the turning cylinder 47 operates to drive the clamp 48 to adjust the angle, the clamp 48 is deflected to a vertical posture under the pushing of the turning cylinder 47, at this time, the position adjusting cylinder on the clamp 48 operates to adjust the distance between the vertical clamp 48 and the turning cylinder 47, so that the clamp 48 can approach the workpiece on the vacuum suction plate 45, the clamping cylinder on the clamp 48 pushes the clamping part of the clamp 48 to clamp the workpiece at this time, then the turning cylinder 47 operates to push the clamp 48 to flip, at this time, the clamp 48 will synchronously drive the clamped workpiece to flip, and the workpiece is flipped to the upper side of the PCB plate fixing module 5 and released to the upper side of the vacuum suction plate 55;

[0048] The bottom end of the receiving box 51 is provided with a horizontal adjusting guide rail 2, and the setting direction of the horizontal adjusting guide rail 2 is perpendicular to the setting direction of the conveying guide rail 1, so that the receiving box 51 can slide horizontally above the conveying guide rail 1 perpendicular to the setting direction of the conveying guide rail 1, that is, the PCB plate fixing module 5 can be displaced synchronously through the horizontal adjusting guide rail 2, so that the PCB plate fixing module 5 is positioned with the clamp 48, and the upper surface of the vacuum suction plate 55 is also provided with a small hole for negative pressure suction, and the vacuum suction plate 55 is connected with a vacuum pump outside through a pipeline, and the vacuum suction plate 55 operates to perform negative pressure adsorption on the workpiece, so that the workpiece on the vacuum suction plate 55 is stably placed;

[0049] The second servo motor 52 in the PCB plate fixing module 5 can adjust the angle of the vacuum suction plate 55 in the horizontal direction by driving the rotation of the output shaft during operation, so as to adjust the angle of the workpiece, and then facilitate the positioning of the workpiece, and the driven pusher 53 and the positioning protrusion 54 in the PCB plate fixing module 5 can accurately limit and position the position of the vacuum suction plate 55, so as to facilitate the fine processing operation of the workpiece by the processing equipment above the PCB plate fixing module 5.

[0050] The above is only the preferred embodiment of the present application, and is not intended to further limit the present application, and any equivalent changes made according to the content of the specification and drawings of the present application are within the scope of protection of the present application.
