[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] The following is combined with Figures 1-3 The workpiece processing system involved in the present utility model will be further explained.

[0034] In an embodiment of a workpiece processing system, the workpiece processing system includes a base frame 1, a plurality of workbenches 4, a plurality of processing mechanisms 2, a plurality of control modules, and a plurality of light curtain mechanisms 3. The workbench 4 is used to place workpieces. A plurality of workpiece processing system structures 2 are arranged on the base frame 1, and at least one processing mechanism 2 is correspondingly arranged for each workbench 4. A plurality of control modules are respectively connected to the processing mechanisms 2 correspondingly arranged for each workbench 4. A plurality of light curtain mechanisms 3 are in one-to-one correspondence with a plurality of workbenches 4 respectively. The light curtain mechanism 3 is connected to the control module corresponding to the workbench 4. The light curtain mechanism 3 includes a transmitting end 31 and a receiving end 32. The transmitting end 31 is used to emit light, and the receiving end 32 is used to receive light. When the light is blocked, the control module controls the processing mechanism 2 to stop working.

[0035] In this embodiment, multiple processing mechanisms 2 are provided. They can work independently through the control module to process different types of workpieces. Multiple light curtain mechanisms 3 are also provided, and each light curtain mechanism 3 corresponds to each processing mechanism 2 one by one. In this way, any processing mechanism 2 can work independently further, achieving the technical effect that when one processing mechanism 2 is working, other processing mechanisms 2 can stop, thus solving the technical problem that the existing workpiece processing system is not flexible enough.

[0036] It should be noted that the two processing mechanisms 2 also work independently. For example, independent systems can be used for control, so that they do not interfere with each other and can work and stop separately.

[0037] Specifically, in an embodiment of a workpiece processing system, the base frame 1 includes a bed body 11, a base 13 and a cross beam 12. The workbench 4 is arranged on the bed body 11, the base 13 is installed on the bed body 11, and both ends of the cross beam 12 are connected to the base 13. The processing mechanism 2 is arranged on the cross beam 12. The cross beam 12 forms a gantry structure.

[0038] In an embodiment of a workpiece processing system, the workpiece processing system further includes a machine cover. The machine cover covers the base frame 1, and the light curtain mechanism 3 is arranged on the inner wall of the machine cover.

[0039] In this embodiment, by setting the machine cover, a closed processing space can be formed. By arranging the light curtain mechanism 3 on the inner wall of the machine cover, the space occupied on the base frame 1 can be reduced, and the light curtain mechanism 3 can be directly removed after removing the machine cover, which is convenient for subsequent operations of the staff.

[0040] In an embodiment of a workpiece processing system, the light curtain mechanism 3 includes multiple brackets 9. The brackets 9 are arranged on the inner wall of the machine cover, and two brackets 9 are correspondingly arranged for each workbench 4. The receiving end 32 is arranged on one of the two brackets 9, and the transmitting end 31 is arranged on the other of the two brackets 9. Or, the light curtain mechanism 3 includes multiple brackets 9 arranged at intervals on the inner wall of the machine cover. There is one workbench 4 arranged between two brackets 9, and a transmitting end 31 of a light curtain mechanism 3 and a receiving end 32 of another light curtain mechanism 3 are installed on the bracket 9 located between the two workbenches 4.

[0041] By setting the brackets 9 to carry the receiving end 32 and the transmitting end 31, it is convenient to fix the receiving end 32 and the transmitting end 31. Preferably, the bracket 9 can also play an adjusting role. For example, the bracket 9 is set as a telescopic structure with adjustable length, so that the corresponding relationship between the receiving end 32 and the transmitting end 31 and the workbench 4 can be adjusted better.

[0042] When the transmitting end 31 and the receiving end 32 are commonly installed on the middle bracket 9, it is beneficial to reduce the occupied space for miniaturization.

[0043] In an embodiment of a workpiece processing system, the workpiece processing system further includes at least one anti-collision block 8, and the anti-collision block 8 and the workbench 4 are alternately arranged at intervals.

[0044] In this embodiment, the anti-collision block 8 is a solid block structural member. By setting the solid anti-collision block 8, it can be placed on the moving path of the processing mechanism 2 to achieve the effect of physical limitation.

[0045] In an embodiment of a workpiece processing system, the workpiece processing system further includes a driving mechanism. The driving mechanism is arranged on the base frame 1. The driving mechanism includes a plurality of first driving components 5 and a plurality of second driving components 6. The output ends of the plurality of first driving components 5 are respectively connected to the plurality of workbenches 4 in one-to-one correspondence to drive the workbench 4 to move in the first direction. The output ends of the plurality of second driving components 6 are respectively connected to the plurality of processing mechanisms 2 in one-to-one correspondence to drive the processing mechanism 2 to move in the second direction and the third direction. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. The control module is also communicatively connected to the first driving component 5 and the second driving component 6, so as to be able to control the first driving component 5 and the second driving component 6 to stop working when the light is blocked.

[0046] In this embodiment, under the drive of the first driving component 5 and the second driving component 6, the workbench 4 and the processing mechanism 2 can cooperate to form a variety of motion modes. Taking the first direction as the Y direction as an example, three motion modes of XY, YZ, and XYZ can be formed, so that the processing mechanism 2 can be made to correspond to the position to be processed on the workpiece by the moving mode.

[0047] It should be noted that one control module corresponds to one workbench 4, one workbench 4 corresponds to one first driving component 5, one second driving component 6, one light curtain mechanism 3, and one processing mechanism 2. When the optical fiber is blocked, all actions corresponding to the workbench 4 can be paused by the control module.

[0048] In an embodiment of a workpiece processing system, it further includes a plurality of limiting mechanisms. The plurality of limiting mechanisms are respectively communicatively connected to the plurality of second driving components 6 in one-to-one correspondence. One processing mechanism 2 is arranged between two adjacent limiting mechanisms to limit the moving stroke of the processing mechanism 2. The number of the anti-collision blocks 8 is multiple. One processing mechanism 2 is arranged between two adjacent anti-collision blocks 8. The two limiting mechanisms corresponding to the same processing mechanism 2 are both located between the two anti-collision blocks 8.

[0049] In this embodiment, by providing a limiting mechanism capable of communicatingly connecting with the second driving component 6, the automation level can be improved. Specifically, the limiting mechanism includes a photoelectric switch 7. A sheet-like structural member is provided on the processing mechanism. During the movement of the sheet-like structural member following the processing mechanism 2, it can extend between the emitting part and the receiving part of the photoelectric switch 7 to trigger the photoelectric switch 7. Photoelectric switches 7 are provided at both ends of the stroke of the processing mechanism 2 driven by the second driving component 6.

[0050] In addition, it can be understood that two photoelectric switches 7 form the first-level protection, while two anti-collision blocks 8 outside the two photoelectric switches 7 form the second-level protection. The photoelectric switch 7 is an electrified automatic control, while the anti-collision block 8 is a physical limitation of the solid structure. By such an arrangement, potential safety hazards caused by the failure of the photoelectric switch 7 can be avoided, and collisions between adjacent two processing mechanisms 2 can be avoided, improving safety.

[0051] In an embodiment of a workpiece processing system, each second driving component 6 includes a first driving member 61 and a second driving member. The output end of the first driving member 61 is connected to the processing mechanism 2 to drive the processing mechanism 2 to move in the second direction, and the output end of the second driving member is connected to the processing mechanism 2 to drive the processing mechanism 2 to move in the third direction.

[0052] In this embodiment, by providing the first driving member 61 and the second driving member in the second driving component 6, the processing mechanism 2 can be moved in a plane, such as the XZ plane. In addition, a carrier 62 can be added. The first driving member 61 is installed on the carrier 62. The carrier 62 can be a slide rail. The first driving member 61 slides on the slide rail. The output end of the second driving member is connected to the first driving member 61. By driving the first driving member 61, the processing mechanism 2 is driven to move. The driving mode of the second driving member can be to drive the first driving member 61 through a chain connection. The carrier 62 can also be the driving end of the second driving member. Specifically, the second driving member can be combined with the carrier 62. For example, the carrier 62 can be a structural member such as a transmission chain or a belt. The second driving member is used to drive the carrier 62 to rotate, which can not only play a guiding role but also be responsible for transmission.

[0053] Combined with the previous embodiment, the first direction can be the Y direction, the second direction can be the Z direction, and the third direction can be the X direction. Among them, the first direction, the second direction, and the third direction can be perpendicular to each other in pairs.

[0054] In addition, combined with the previous embodiment, specifically, the workpiece is a PCB board. The processing mechanism 2 includes a processing spindle and a tool. The output shaft of the processing spindle is connected to the tool. The tool is used for drilling and / or grooving on the PCB board, that is, the processing spindle can drive the tool to perform drilling, or grooving, or drilling and grooving and other processing on the PCB board.

[0055] The specific workpiece processing system can be a drilling machine, a milling machine (shaping machine), or a drilling and milling integrated machine.

[0056] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0057] The above embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
