[0046] Specifically, see Figures 1 to 3 , Figure 1 It is a three-dimensional structural schematic diagram of an embodiment of the processing platform of the present application. Figure 2 It is a schematic diagram of the top view of the structure of an embodiment of the processing platform of the present application. Figure 3 It is a rear view structural schematic diagram of an implementation method of a processing platform of the present application.

[0047] like Figures 1 to 3 As shown, the processing platform includes a workbench 100 , and the workbench 100 includes a bearing surface 101 for bearing a workpiece and a back surface 102 disposed opposite to the bearing surface 101 .

[0048] The workbench 100 is provided with a first through hole 103 and a second through hole 104 penetrating therethrough.

[0049] In order to ensure the surface accuracy of the carrying surface 101 , the workbench 100 in this embodiment includes a marble tabletop 105 and a glass panel 106 arranged on the surface of the marble tabletop 105 , and the carrying surface 101 is arranged on the surface of the glass panel 106 .

[0050] The processing platform further includes a marble column 200 for supporting the marble table plate 105 .

[0051] The marble material may be natural marble, which will not have strong internal stress released over time after a long period of natural aging, and can ensure the accuracy of the bearing surface 101 ; the glass panel 106 may be high-precision glass to ensure the accuracy of the bearing surface 101 .

[0052] It is understandable that in other embodiments, in scenarios where the precision requirement is not high, the workbench 100 may also be made of other materials and may also be able to support the workpiece.

[0053] The processing platform also includes a vacuum adsorption unit 300, which includes a vacuum branch pipe 301. The vacuum branch pipe 301 corresponds one-to-one to the first through hole 103. The vacuum branch pipe 301 extends from the back side 102 to the first through hole 103. The vacuum adsorption unit 300 is used to form a negative pressure on the supporting surface 101 for adsorbing the workpiece through the vacuum branch pipe 301 and the first through hole 103.

[0058] It can be understood that, based on the vacuum adsorption unit 300 , the workpiece can be adsorbed and fixed on the carrying surface 101 by negative pressure during operation, thereby ensuring the fixation stability of the workpiece.

[0059] Furthermore, in order to ensure the position accuracy of the workpiece when it is transferred to the bearing surface 101, the processing platform also includes a guide unit 400 and a lifting unit 500. The guide unit 400 includes a first support arm 401 and a first guide wheel 402. The first support arm 401 corresponds to the second through hole 104 one by one. The support arm is inserted into the second through hole 104 from the back side 102. The first guide wheel 402 is arranged at the end of the first support arm 401. The first guide wheel 402 includes an extended posture extending from the bearing surface 101 and a retracted posture retracted below the bearing surface 101.

[0060] The lifting unit 500 is used to drive the first support arm 401 to move up and down, so as to control the first guide wheel 402 to switch between an extended posture and a retracted posture.

[0061] It can be understood that when the workpiece is being transported, the lifting unit 500 can be used to drive the first guide wheel 402 to extend out of the carrying surface 101, and the workpiece can be transferred to the position by the first guide wheel 402; when the workpiece is transported to the position, the lifting unit 500 can be used to drive the first guide wheel 402 to retract below the carrying surface 101, without affecting the adsorption and fixation of the workpiece by the vacuum adsorption unit 300.

[0062] Specifically, in this embodiment, a plurality of second through holes 104 are arranged on the workbench 100 , and correspondingly, the guide unit 400 includes a plurality of first support arms 401 corresponding one-to-one to the plurality of second through holes 104 .

[0063] The guide unit 400 further includes one or more support cross bars 403 , which are connected to the plurality of first support arms 401 . The lifting unit 500 can drive the support cross bars 403 to rise and fall, thereby causing the plurality of first support arms 401 and the first guide wheels 402 to rise and fall synchronously.

[0064] In order to ensure the synchronous lifting and lowering of various parts of the workpiece, in this embodiment, the guide unit 400 includes several rows of first support arms 401, each row of first support arms 401 includes one or more first support arms 401 arranged at intervals along the second direction y, and the guide unit 400 may include several support cross bars 403 extending along the second direction y corresponding to the several rows of first support arms 401, and each support cross bar 403 can be connected to the corresponding row of multiple first support arms 401.

[0065] Furthermore, in this embodiment, both ends of the support cross bar 403 also extend to the outside of the workbench 100, and the processing platform also includes a second support arm 404 and a second guide wheel 405. The second support arm 404 is arranged at the outer end of the support cross bar 403, and the bottom end of the second support arm 404 is connected to the support cross bar 403, and the top end is extended vertically. The second guide wheel 405 is arranged at the top of the second support arm 404, and the second guide wheel 405 is consistent in height with the first guide wheel 402, so that it can adapt to the transmission of workpieces of different sizes.

[0066] In order to facilitate the synchronous lifting and lowering of the first support arms 401 and the second support arms 404, the guide unit 400 in this embodiment also includes a support base 406, which connects multiple support cross bars 403 into one. The lifting unit 500 can be used to drive the support base 406 to lift and lower, thereby driving the multiple support cross bars 403, the first support arms 401 and the second support arms 404 to lift and lower synchronously.

[0067] Specifically, in order to facilitate the arrangement of the supporting cross bar 403 and the vacuum main pipe 303, in this embodiment, the first direction x can be distributed perpendicular to the second direction y, that is, the supporting cross bar 403 and the vacuum main pipe 303 can be distributed perpendicular to each other, and the workbench 100 can be arranged with several rows of first through holes 103 arranged in sequence along the second direction y, and each row of first through holes 103 includes one or more first through holes 103 arranged at intervals along the first direction x; the workbench 100 can be arranged with several rows of second through holes 104 arranged in sequence along the first direction x, and each row of second through holes 104 includes one or more second through holes 104 arranged at intervals along the second direction y.

[0068] Of course, in other embodiments, the extension directions of the support cross bar 403 and the vacuum main pipe 303 may not be vertically distributed, as long as the vacuum main pipe 303 does not interfere with the lifting and arrangement of the support cross bar 403, and the effect of this embodiment can be achieved.

[0069] Furthermore, in order to accurately confirm the position error of the workpiece during the laser scribing operation, the processing platform in this embodiment also includes an image acquisition unit 600, which is arranged on one side of the workbench 100. The image acquisition unit 600 is used to capture the edge image of the workpiece to obtain the actual position of the workpiece.

[0070] The image acquisition unit 600 may include a camera 601 and a displacement element 602 for driving the position of the camera 601 so that the field of view of the camera 601 can be aligned with the edge of the workpiece.

[0071] The actual position of the workpiece can be obtained based on the workpiece edge image collected by the image acquisition unit 600. The position deviation value of the workpiece can be determined based on the difference between the actual position and the preset position, and the compensation data value of each axis processing element can be calculated based on the position deviation value to improve the processing accuracy.

[0072] The following is a detailed structural diagram of the lifting unit 500 of the present application. Figure 4 , Figure 4 yes Figure 2 Schematic diagram of the cross-sectional structure of the AA surface in the middle.

[0073] like Figure 4 As shown, the lifting unit 500 includes a mounting seat 501 , which is arranged beside the workbench 100 , and a lifting guide rail 502 is arranged on one side of the mounting seat 501 .

[0074] A slide plate 503 is slidably mounted on the lifting guide rail 502 , and the slide plate 503 is connected to the lifting seat.

[0075] A lifting drive element 504 for driving the sliding plate 503 to move up and down is also arranged on the mounting seat 501. Specifically, in this embodiment, the lifting drive element 504 includes a lifting motor 5041, a screw rod 5042 arranged at the output end of the lifting motor 5041, and a nut 5043 arranged on the sliding plate 503.

[0076] In other embodiments, the lifting drive element 504 may also be other commonly used elements, such as an electric cylinder, a pneumatic cylinder, etc., which can achieve the effect of this embodiment.

[0077] See also Figures 1 to 3 In this embodiment, the processing platform includes two work tables 100 arranged at intervals. In order to enable the first guide wheels 402 of the two work tables 100 to rise and fall synchronously, the lifting unit 500 can be arranged at the gap between the two work tables 100 and synchronously connected to the guide units 400 on both sides; in other embodiments, the work table 100 and the lifting unit 500 can also adopt other arrangements.

[0078] Based on the processing platform of the above-mentioned embodiments, when the workpiece is transported, the first guide wheel 402 and the second guide wheel 405 can be controlled to extend out of the carrying surface 101 through the lifting unit 500, and the workpiece can be transferred to the processing station under the action of the first guide wheel 402 and the second guide wheel 405; after being transferred to the processing station, the first guide wheel 402 and the second guide wheel 405 can be controlled to retract below the carrying surface 101 through the lifting unit 500, and at the same time drive the workpiece to be close to the carrying surface 101, and at this time, the vacuum generating element 302 can be turned on to make the workpiece adsorbed and fixed on the carrying surface 101 under the action of negative pressure, so as to ensure the position accuracy and fixing stability of the workpiece, thereby significantly improving the processing accuracy.
