The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

A table 10 of a processing apparatus 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, a table 10 of a processing apparatus 100 according to an embodiment of the first aspect of the present invention includes: the machining platform 1, the clamping device 2, the guiding device 3, the first sensor 51 and the second sensor 52, wherein the machining platform 1 is used for placing a to-be-machined workpiece 200, and a positioning piece 201 is arranged on the to-be-machined workpiece 200. The clamping device 2 is arranged on the processing platform 1, the guiding device 3 is arranged on the processing platform 1, the to-be-processed workpiece 200 is suitable for being conveyed to the processing platform 1 along a first direction (refer to the front-back direction in the figure) under the guidance of the guiding device 3, and is suitable for clamping the positioning piece 201 by the clamping device 2 so as to clamp and position the to-be-processed workpiece 200, and the first direction can be parallel to the horizontal direction.

For example, the workpiece 200 may be a PCB board, and the positioning member 201 may be a pin; the machining apparatus 100 may be a drilling apparatus, for example, the machining apparatus 100 may be a PCB drill, and the machining apparatus 100 may drill the workpiece 200. Before the processing device 100 processes the workpiece 200, the clamping device 2 can clamp the positioning piece 201 to reliably position the workpiece 200 at a preset position, so that the workpiece 200 is prevented from rotating during processing to reduce the processing precision or discard the workpiece, the processing precision is improved, and the qualification rate and quality of products are improved.

For example, the guide device 3 is provided with a guide groove 32 extending in a first direction (refer to the front-rear direction in the drawing), and the positioning member 201 may be accommodated in the guide groove 32. The workbench 10 is further provided with a first conveying device 4, the first conveying device 4 comprises first conveying belts 41 arranged on two sides of the clamping device 2, and the first conveying belts 41 can drive the workpiece 200 to be processed to move in a first direction. The first transfer device 4 can be used for transferring the workpiece 200 from outside the machining table 1 onto the machining table 1 and for transferring the workpiece 200 from above the machining table 1 to outside the machining table 1.

For example, referring to fig. 16 to 19, the processing apparatus 100 includes a machine table 60, a table 10, a beam 70, a processing mechanism 80, and a protective cover 90, the table 10 is disposed on an upper surface of the machine table 60, the table 10 further includes a driving bracket 101, a plurality of processing platforms 1 are disposed on the driving bracket 101, a sliding rail 601 is disposed between the driving bracket 101 and the upper surface of the machine table 60, and the driving bracket 101 can move in a first direction (refer to a front-rear direction in the drawing) through the sliding rail 601 to drive the processing platforms 1 to move in the first direction. The beam 70 is disposed on the machine 60 and is located at the rear end of the machine 60, a space for the table 1 to move in the first direction is defined between the lower side of the beam 70 and the upper surface of the machine 60, and a material inlet/outlet 701 is formed between the lower side of the beam 70 and the machine 60. The machining mechanism 80 is provided on the cross member 70, and the machining mechanism 80 is movable in the left-right direction along the cross member 70. The processing mechanism 80 includes a spindle 801, and the spindle 801 is movable in the up-down direction relative to the cross member 70. The protection cover 90 is arranged above the machine 60 in a covering manner, so that the cross beam 70, the workbench 10 and the processing mechanism 80 can be covered, and therefore, scraps generated during the operation of the processing equipment 100 can be prevented from splashing, and the personal safety of operators is ensured.

For example, referring to fig. 14 to 19, the processing apparatus 100 is a ring in a production line of the to-be-processed workpiece 200, and the production line of the to-be-processed workpiece 200 further includes a relay mechanism 300, the relay mechanism 300 is disposed at a rear side of the processing apparatus 100, and the relay mechanism 300 is configured to interface with the workbench 10 of the processing apparatus 100. The transfer mechanism 300 is further provided with a second conveying device comprising a second conveyor belt 301 abutting against the first conveyor belt 41, the first conveyor belt 41 and the second conveyor belt 301 being capable of driving the workpiece 200 to be processed in a first direction for conveying the workpiece 200 to the table 10 and for transferring processed workpieces on the table 10 to the transfer mechanism 300.

For example, the production line of the workpiece 200 may further include a transport mechanism and a magazine adapted to store the workpiece 200, the transport mechanism being capable of transporting the workpiece 200 from the magazine to the transfer mechanism 300. When the workpiece 200 needs to be processed, the workpiece 200 can be conveyed to the transfer mechanism 300 by the conveying mechanism from the stock bin, the workbench can move to the rear of the processing equipment 100 in the first direction, the guide device 3 of the workbench passes through the feeding and discharging hole 701, the second conveyor 301 on the transfer mechanism 300 is abutted with the first conveyor 41 on the workbench 10, and therefore the workpiece 200 can be transferred to the processing platform 1, and during transfer, the workpiece 200 is guided at the guide device 3 first, namely the positioning piece 201 enters the guide groove 32 and moves towards a preset position along the guide groove 32 in the first direction (front-rear direction in the reference drawing). After the workpiece 200 is transferred onto the processing platform 1, the first conveying device 4 may convey the workpiece 200 to a preset position of the processing platform 1. By providing the guide groove 32, the workpiece 200 can be prevented from tilting during the transfer process, so that the workpiece 200 can be more accurately transferred to the preset position of the processing table 1.

The first sensor 51 is provided to the guide 3 for detecting whether the positioning member 201 passes through the guide 3; for example, the first sensor 51 may detect the positioning member 201 and transmit a detection signal to the control system of the processing apparatus 100 when the positioning member 201 passes through the guide device 3, so that the control system may record the number of positioning members 201 passing through the guide device 2. When the workpiece 200 is transferred from the transfer mechanism 300 to the preset position of the processing platform 1, the control system records that the number of positioning members 201 passing through the guiding device 2 is equal to the preset number of positioning members 201 on the workpiece 200.

After the workpiece 200 moves onto the processing platform 1, if the control system determines that the number of the positioning pieces 201 is normal, the clamping device 2 is controlled to clamp the positioning pieces 201 so as to position the workpiece 200 at a preset position. When the control system records that the number of the positioning pieces 201 passing through the guiding device 2 is smaller than the preset number of the positioning pieces 201 on the to-be-processed workpiece 200, the control system judges that the positioning pieces 201 fall off from the to-be-processed workpiece 200, and the to-be-processed workpiece 200 is abnormal, the control system controls the alarm device to give an alarm, such as giving a warning light or giving a warning bell, so as to remind an operator of processing the abnormal to-be-processed workpiece 200, such as replacing the preset number of the positioning pieces 201 to-be-processed workpiece 200 with normal number.

After the control system judges that the number of the positioning pieces 201 on the workpiece 200 is normal, the control system controls the clamping device 1 to clamp the positioning pieces 201, so that the clamping device 2 can not clamp and position the workpiece 200 through the clamping positioning pieces 201, the workpiece 200 is prevented from rotating during processing to reduce the processing precision or discard the workpiece, the workpiece 200 can be reliably and accurately positioned at a preset position, and thereafter, the control system controls the processing equipment 100 to process the workpiece 200, so that the processing precision of the workpiece 200 can be ensured, and the qualification rate and quality of products are improved.

The second sensor 52 is provided on the processing platform 1, and the second sensor 52 may be used to detect whether the workpiece 200 is at a predetermined position on the processing platform 1, and/or the second sensor 52 may be used to detect a distance H between a lower surface of the workpiece 200 and an upper surface of the processing platform 1. For example, the second sensor 52 may be used only for detecting whether the workpiece 200 to be machined is at a preset position on the machining table 1. The machining platform 1 has a first end and a second end opposite to each other along a first direction, the guiding device 3 is arranged at the first end, the second sensor 52 is arranged at the second end, when the workpiece 200 is at a preset position, an end of the workpiece 200 adjacent to the second end is opposite to the second sensor 52 in an up-down direction, after the end of the workpiece 200 adjacent to the second end covers the second sensor 52, the second sensor 52 is triggered, the second sensor 52 can transmit a detection signal to a control system of the machining device 100, and the control system determines that the workpiece 200 is at the preset position.

After the clamping device 2 clamps the positioning member 201, if the control system does not receive the detection signal of the second sensor 52, the control system determines that the workpiece 200 is in an abnormal state, for example, the workpiece 200 is askew, the workpiece 200 does not reach the preset position, and the control system controls the alarm device to alarm, for example, to emit a warning light or a warning bell, so as to remind the operator to process the workpiece 200 in the abnormal state. After the operator returns the workpiece 200 in the normal state to the processing platform, the second sensor 52 detects whether the workpiece 200 is at a preset position on the processing platform 1, and after the control system determines that the workpiece 200 is at the preset position, the control system controls the processing apparatus 100 to process the workpiece 200. Thus, the machining precision of the workpiece 200 to be machined can be ensured, and the quality and the qualification rate of products can be improved.

For another example, the second sensor 52 may be used only to detect the distance H between the lower surface of the workpiece 200 and the upper surface of the processing table 1. For example, when the workpiece 200 is at the preset position, the workpiece 200 may cover the second sensor 52 such that the second sensor 52 may detect a distance between the lower surface of the workpiece 200 and the upper surface of the processing table 1.

For example, when the foreign matter 400 exists between the workpiece 200 and the processing platform 1, the workpiece 200 may warp, and when the distance H between the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is greater than a certain value, the processing precision of the workpiece 200 may be affected, or even the product may be scrapped. The control system may set the value to a preset value, and detect the distance H between the lower surface of the workpiece 200 and the upper surface of the processing table 1 using the second sensor 52 and compare the detected distance H with the preset value before the processing apparatus 100 processes the workpiece 200. Wherein the preset value may be 0.5mm.

If the distance H between the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is not greater than the preset value, it indicates that the workpiece 200 is relatively flat, and then the control system controls the processing device 100 to process the workpiece 200, so that the processing precision can be ensured, and the quality and qualification rate of the product can be improved.

If the distance between the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is greater than the preset value, it is possible that the workpiece 200 is warped, or that the workpiece 200 is inclined due to the foreign matter 400 existing between the workpiece 200 and the processing platform 1, the control system controls the alarm device to alarm, so as to remind the operator of timely handling the abnormal state. For example, when the workpiece 200 is warped, the operator can replace the workpiece 200 with a new one; when the workpiece 100 is tilted due to the presence of the foreign matter 400 between the workpiece 200 and the processing table 1, the operator cleans the processing table 1.

After the operator finishes the abnormal state processing, the second sensor 52 is used for detecting the distance H between the lower surface of the workpiece 200 and the upper surface of the processing platform 1, and after the second sensor 52 detects that the distance H between the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is not greater than a preset value, the control system controls the processing equipment 100 to process the workpiece 200. The workbench 10 can avoid the processing of the workpiece 200 in a warping state or an inclined state by the processing equipment 100 by arranging the second sensor 52 to detect the distance H between the lower surface of the workpiece 200 and the upper surface of the processing platform 1, ensure the processing precision of the workpiece 200 and improve the quality and qualification rate of products.

For another example, the second sensor 52 may be used to detect not only whether the workpiece 200 is at a preset position on the processing table 1, but also the distance H between the lower surface of the workpiece 200 and the upper surface of the processing table 1. For example, when the workpiece 200 is at the preset position, an end portion of the workpiece 200 adjacent to the second end is opposite to the second sensor 52 in the up-down direction, the workpiece 200 may cover the second sensor 52 such that the second sensor 52 may detect the distance H between the lower surface of the workpiece 200 and the upper surface of the processing table 1. If the workpiece 200 is not at the preset position, the workpiece 200 cannot be covered by the second sensor 52, and the second sensor 52 cannot detect the distance H between the lower surface of the workpiece 200 and the upper surface of the processing table 1.

In this way, after the second sensor 52 detects that the workpiece 200 is at the preset position, the distance H between the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is detected, so that the control system can determine whether the surface of the workpiece 200 is flat or whether the foreign matter 400 exists between the workpiece 200 and the processing platform 1, thereby avoiding the workpiece 200 with uneven processing surface by the processing equipment 100, ensuring the processing precision of the workpiece 200, improving the quality and qualification rate of the product, and reducing the production cost. The number of second sensors 52 used can also be reduced, reducing the cost of manufacturing the table 10.

According to the workbench 10 of the processing apparatus 100 of the embodiment of the present invention, by setting the first sensor 51, it is possible to detect whether the positioning member 201 on the workpiece 200 falls off, by setting the second sensor 52, it is possible to detect whether the workpiece 200 reaches a preset position or whether the workpiece 200 is warped or whether there is a large foreign object between the lower surface of the workpiece 200 and the processing platform 1, thereby preventing the processing apparatus 100 from processing the workpiece 200 in an abnormal state, ensuring the processing precision of the workpiece 200, and improving the yield and quality of products.

Referring to fig. 1, 4-8, according to some embodiments of the present invention, the guiding device 3 includes a guiding plate 31, a guiding groove 32 is formed on the guiding plate 31 along a first direction (referring to a front-rear direction in the drawing), a first sensor 51 is disposed at a side wall of the guiding groove 32, and the first sensor 51 is an opposite-emitting photoelectric sensor or a reflective photoelectric sensor. The first sensor 51 may also be a proximity sensor or a metal sensor, for example.

For example, when the workpiece 200 is transferred from the transfer mechanism 300 to the processing table 1 and the workpiece 200 is transferred from the processing table 1 to the transfer mechanism 300, the positioning member 201 may move in the guide groove 32 in the first direction so that the photoelectric signal of the first sensor 51 changes, so that the control system may determine that the positioning member 201 passes through the guide groove 32 and record information that the positioning member 201 passes through the guide groove 32, so that the control system determines whether the positioning member 201 falls off according to the number of times the photoelectric signal of the first sensor 51 changes.

For example, two positioning members 201 on the workpiece 200 may be provided, in the process that the workpiece 200 is transferred from the transfer mechanism 300 to the preset position of the processing platform 1, both positioning members 201 will pass through the guide groove 32, so that the photoelectric signal of the first sensor 51 changes twice, so that the control system may record information that the two positioning members 201 pass through the guide groove 32, the preset number of the positioning members 201 is the same as the number of times that the positioning members 201 pass through the guide groove 32, and the control system determines that no positioning member 201 falls off. After the second sensor 52 is triggered, if the photoelectric signal of the first sensor 51 changes only once, the number of times that the positioning piece 201 passes through the guide groove 32 is smaller than the preset number of the positioning pieces 201, the control system judges that the positioning pieces 201 fall off, the to-be-processed workpiece 200 is abnormal, the control system controls the alarm device to alarm, reminds an operator to timely process the to-be-processed workpiece 200, prevents the processing equipment 100 from processing the to-be-processed workpiece 200 in an abnormal state, improves the processing precision, and improves the qualification rate and the quality of products.

When the processing of the workpiece 200 is completed, the workpiece 200 is transferred from the processing platform 1 to the transfer mechanism 300, both positioning pieces 201 pass through the guide groove 32, so that the photoelectric signal of the first sensor 51 changes twice, the control system can record the information that the positioning pieces 201 pass through the guide groove 32 twice, the number of the positioning pieces 201 is the same as the number of times that the positioning pieces 201 pass through the guide groove 32, and the control system judges that no positioning piece 201 falls off. If the photoelectric signal of the first sensor 51 changes only once, the number of times that the positioning piece 201 passes through the guide groove 32 is smaller than the number of the positioning pieces 201, the control system determines that the positioning pieces 201 fall off, the to-be-machined piece 200 is abnormal, and the control system controls the alarm device to alarm, so that an operator is reminded of timely treating the to-be-machined piece 200, and the falling of the positioning pieces 201 is prevented, so that the to-be-machined piece 200 is influenced in the next machining process, and the machining precision of the part is reduced.

Referring to fig. 1, 14 and 15, according to some embodiments of the present invention, the processing platform 1 has opposite first and second ends along a first direction (referring to a front-rear direction in the drawings), the guide 3 is provided at the first end, the second sensor 52 is provided at the second end, and when the workpiece 200 is at a preset position, an end of the workpiece 200 adjacent to the second end is opposite to the second sensor 52 in an up-down direction. For example, when the workpiece 200 is at the preset position, this may enable the second sensor 52 to detect that the workpiece 200 is at the preset position; when the workpiece 200 is skewed and the workpiece 200 is not at the preset position, the second sensor 52 is made unable to detect that the workpiece 200 is at the preset position. The second sensor 52 is arranged at the second end of the processing platform 1 in the workbench 10, so that the end, adjacent to the second end, of the workpiece 200 is opposite to the second sensor 52 in the up-down direction, and the second sensor 52 can accurately detect whether the workpiece 200 is at the preset position, so that the detection accuracy of the second sensor 52 is improved.

Referring to fig. 1, 14 and 15, according to some embodiments of the present invention, the second sensors 52 are plural, and the plural second sensors 52 are located on opposite sides of the clamping device 2 in a second direction (refer to a left-right direction in the drawing), the second direction may be parallel to the horizontal direction, and the second direction (refer to the left-right direction in the drawing) is perpendicular to the first direction (refer to the front-rear direction in the drawing). For example, the plurality of second sensors 52 are arranged at intervals in the direction in which the end portion of the workpiece 200 adjacent to the second end is located. Therefore, the to-be-machined workpiece 200 can be covered by all the second sensors 52 only when being positioned at the preset position, and when the to-be-machined workpiece 200 is less askew, at least one second sensor 52 cannot be covered by the to-be-machined workpiece 200, so that whether the to-be-machined workpiece 200 is positioned at the preset position can be accurately detected, the to-be-machined workpiece 200 which is not positioned at the preset position is prevented from being machined by the machining equipment 100, the machining precision of the to-be-machined workpiece 200 is ensured, the quality and the qualification rate of products are improved, and the production cost is reduced.

For example, referring to fig. 1, 14 and 15, the two second sensors 52 are provided on opposite sides of the holding device 2 in the second direction (right-left direction in the drawing), and an end portion of the workpiece 200 adjacent to the second end is opposite to the second sensor 52 in the up-down direction. Therefore, the control system can more accurately detect whether the workpiece 200 to be processed is at the preset position, the number of the second sensors 52 can be reduced, and the manufacturing cost of the workbench 10 is reduced.

It should be noted that in the description of the present invention, "a plurality" means two or more.

Referring to fig. 1, 14 and 15, according to some embodiments of the present invention, at least one third sensor 53 is further provided on the processing platform 1, and the third sensor 53 is configured to detect a distance between a lower surface of the workpiece 200 to be processed and an upper surface of the processing platform 1. For example, the distance between the lower surface of the workpiece 200 and the upper surface of the processing table 1 is generally not more than 0.5mm, and the control system may set the preset value to 0.5mm. When the third sensor 53 detects that the distance between the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is greater than 0.5mm, the control system determines that the workpiece 200 is in an abnormal state, and the control system controls the alarm device to alarm, so as to remind an operator of timely processing the abnormal state, such as cleaning the processing platform 1. When the third sensor 53 detects that the distance between the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is not greater than 0.5mm, the control system controls the processing device 100 to process the workpiece 200, so that the processing device 100 can be prevented from processing the workpiece 200 in a warped state or an inclined state, the processing precision of the workpiece 200 is ensured, and the qualification rate and quality of products are improved.

Referring to fig. 1, 14 and 15, according to some embodiments of the present invention, the third sensors 53 are plural, and the plural third sensors 53 are located on opposite sides of the clamping device 2 in a second direction (refer to a left-right direction in the drawing), and the second direction (refer to the left-right direction in the drawing) is perpendicular to the first direction (refer to a front-rear direction in the drawing). For example, when the workpiece 200 is at the preset position, the workpiece 200 may cover the plurality of third sensors 53, and the plurality of third sensors 53 may be disposed at intervals. The plurality of third sensors 53 may detect data of distances between the lower surfaces of the plurality of workpieces 200 and the upper surface of the processing table 1 before the processing apparatus 100 processes the workpieces 200, and the control system may perform an averaging process on the plurality of data.

If the average value of the data is not greater than the preset value, the control system judges that the surface of the workpiece 200 to be processed is flat; if the average value of the data is smaller than the preset value, the control system determines that the workpiece 200 is in an abnormal state, for example, the workpiece 200 is warped or the workpiece 200 is inclined due to the existence of the foreign matter 400 between the workpiece 200 and the processing platform 1, and controls the alarm device to alarm so as to remind an operator to timely process the workpiece 200 in the abnormal state, for example, when the workpiece 200 is warped, the workpiece 200 is replaced with a new workpiece 200; when the foreign matter 400 exists between the workpiece 200 and the processing platform 1, the processing platform 1 is cleaned.

After the worker finishes the processing of the abnormal problem, the workpiece 200 to be processed can be put back to the processing platform 1, then the second sensor 52 is used for detecting the surface flatness of the workpiece 200 to be processed, and after the second sensor 52 detects that the distance between the lower surface of the workpiece 200 to be processed and the upper surface of the processing platform 1 is not greater than a preset value, the control system controls the processing equipment 100 to process the workpiece 200 to be processed.

The workbench 10 can more accurately detect whether the surface of the workpiece 200 is flat or not, for example, whether the workpiece 200 is warped or not, or whether the foreign matter 400 exists between the workpiece 200 and the processing platform 1 or not, by arranging a plurality of third sensors 53 to detect the distance between the lower surface of the workpiece 200 and the upper surface of the processing platform 1, so that the processing precision of the workpiece 200 is ensured, and the quality and the qualification rate of products are improved.

For example, referring to fig. 1, 14 and 15, there may be two third sensors 53, the two third sensors 53 are respectively located at opposite sides of the clamping device 2 in the second direction (refer to the left-right direction in the drawing), and the distance between the two third sensors 53 is smaller than the width of the minimum circuit board that can be processed. In this way, the surface of the workpiece 200 to be processed can be accurately detected whether the surface is flat or not under the condition that the number of the third sensors 53 is as small as possible, the qualification rate of products is ensured, and the cost of manufacturing the workbench 10 is reduced.

Referring to fig. 1, 14 and 15, according to some embodiments of the present invention, the second sensors 52 and the third sensors 53 are multiple, wherein at least one second sensor 52 is configured to detect a distance between a lower surface of the workpiece 200 and an upper surface of the processing platform 1, an area of a pattern s enclosed by lines connecting the positions of the plurality of third sensors 53 and the at least one second sensor 52 is not less than half of a plane area of the workpiece 200, and the plane area of the workpiece 200 refers to a projected area of the workpiece 200 on a horizontal plane.

Thus, the average value of the data can more accurately reflect the planeness of the whole to-be-machined workpiece 200, so that whether the to-be-machined workpiece 200 is warped or whether the foreign matter 400 exists between the to-be-machined workpiece 200 and the machining platform 1 can be more accurately detected. Thus, the control system is prevented from judging the to-be-machined workpiece 200 in an abnormal state as a flat to-be-machined workpiece 200, and the to-be-machined workpiece 200 in the abnormal state is prevented from being machined, so that the machining precision of the to-be-machined workpiece 200 can be ensured, the quality and the qualification rate of products can be improved, and the production cost can be reduced. Meanwhile, the control system can be prevented from judging the flat to-be-processed workpiece 200 as the abnormal to-be-processed workpiece 200, so that the workload generated by misjudgment of the system is reduced, and the production efficiency of products is improved.

For example, referring to fig. 1, 14 and 15, the second sensors 52 may be two, and the third sensors 53 may be two. In this way, in the case that the number of the second sensors 52 and the third sensors 53 is as small as possible, it is possible to accurately detect whether the workpiece 200 reaches the predetermined position, and it is also possible to more accurately detect whether the workpiece 200 is warped or whether the foreign matter 400 exists between the workpiece 200 and the processing platform 1, thereby reducing the manufacturing cost of the workbench 10.

Wherein the second sensor 52 and the third sensor 53 may each be a ranging sensor.

Referring to fig. 1, 9-11, according to some embodiments of the present invention, the stage 10 of the processing apparatus 100 further includes: a fourth sensor 56, the fourth sensor 56 is arranged on the clamping device 2 for detecting whether the positioning member 201 in the clamping device 2 reaches a preset position. For example, the clamping device 2 is provided with a clamping position, when the positioning piece 201 reaches a preset position, the positioning piece 201 is positioned at the clamping position, so that the clamping device 2 can clamp the positioning piece 201 to position the workpiece 200 to be processed at the preset position, and the workpiece 200 to be processed is prevented from shaking during processing, so that the processing precision and quality of a product can be ensured. The clamping position may be a clamping groove 2141 described below.

If the positioning member 201 is not at the preset position, the clamping device 2 cannot clamp the positioning member 201, or the clamping device 2 cannot position the workpiece 200 to be processed at the preset position after the clamping device 2 clamps the positioning member 201, when the processing device 100 processes the workpiece 200 to be processed, the accuracy of the workpiece 200 to be processed is easily reduced, even the product is scrapped, and the plate is wasted.

For example, when the positioning member 201 is at the preset position, the fourth sensor 56 may sense that the positioning member 201 is in the clamping position, the fourth sensor 56 may transmit the sensing signal to the control system, and the control system determines that the positioning member 201 is at the preset position, and the control system controls the clamping device 2 to clamp the positioning member 201. When the first sensor 51 and the second sensor 52 are triggered, the fourth sensor 56 does not sense that the positioning piece 201 is in the clamping position, the control system determines that the positioning piece 201 is not in the preset position, and when the workpiece 200 is in an abnormal state, the control system controls the alarm device to alarm, so as to remind an operator of timely processing the abnormal state. By setting the fourth sensor 56 to detect whether the positioning member 201 in the clamping device 2 reaches the preset position, the processing equipment 100 can be prevented from processing the workpiece 200 to be processed in an abnormal state, the processing precision of the workpiece 200 to be processed is improved, the quality of products is ensured, the qualification rate of the products is improved, and the production cost is reduced.

Referring to fig. 1, 9-11, according to some embodiments of the present invention, the stage 10 of the processing apparatus 100 further includes: a fourth sensor 56, the fourth sensor 56 is provided on the holding device 2 for detecting whether the foreign matter 400 exists in the holding device 2. For example, the clamping device 2 is provided with a clamping position, when the positioning piece 201 reaches the preset position, the positioning piece 201 is positioned at the clamping position, so that the clamping device 2 can clamp the positioning piece 201 to position the workpiece 200to be processed at the preset position, and the workpiece 200to be processed is prevented from shaking during processing, so that the processing precision and quality of a product can be ensured, and the production cost is reduced. If the foreign matter 400 is present at the preset position, the foreign matter 400 may cause the positioning member 201 not to move to the preset position, or may cause the positioning member 201 to shake when the clamping device 2 clamps the positioning member 201, when the processing apparatus 100 processes the workpiece 200, the accuracy of the processing the workpiece 200 is easily reduced, even the product is scrapped, and the plate is wasted.

For example, the fourth sensor 56 may sense whether the holding position has the foreign matter 400 and the positioning member 201, before the workpiece 200 is required to be transferred from the transferring mechanism 300 to the processing platform 1, the fourth sensor 56 may detect whether the holding position has the foreign matter 400, and if the fourth sensor 56 does not detect that the holding position has the foreign matter 400, the control system determines that the holding device 2 has no foreign matter 400, and the control system controls the first conveying device 4 and the second conveying device to transfer the workpiece 200 from the transferring mechanism 300 to the preset position of the processing platform 1. If the fourth sensor 56 detects that the foreign matter 400 exists in the clamping position, the control system judges that the foreign matter 400 exists in the clamping device 2, and the control system controls the alarm device to alarm so as to remind an operator of timely cleaning the foreign matter 400 in the clamping device 2. After the operator finishes cleaning the foreign matter 400 in the clamping device 2, the control system determines that the clamping device 2 is free of the foreign matter 400, and then the control system controls the first conveying device 4 and the second conveying device to transfer the to-be-machined piece 200 from the transfer mechanism 300 to a preset position of the machining platform 1.

By setting the fourth sensor 56 to detect whether the foreign matter 400 exists in the clamping device 2, the clamping device 2 can be prevented from being unable to clamp and position the positioning piece 201, so that the workpiece 200 to be processed can be reliably positioned at the preset position of the processing platform 1, the processing precision of the processing equipment 100 on the workpiece 200 to be processed is improved, and the qualification rate and quality of products are improved.

Referring to fig. 1, 9-11, according to some embodiments of the present invention, the stage 10 of the processing apparatus 100 further includes: the fourth sensor 56, the fourth sensor 56 is disposed on the clamping device 2, so as to detect whether there is a foreign object 400 in the clamping device 2 and detect whether the positioning member 201 in the clamping device 2 reaches a preset position. For example, the fourth sensor 56 may be used to detect the presence of foreign objects 400 in the holding device 2 before the workpiece 200 is transferred onto the processing table 1; after the workpiece 200 is transferred to the processing table, the fourth sensor 56 detects whether the positioning member 201 in the holding device 2 reaches a preset position.

For example, the fourth sensor 56 may sense whether an object is present in the clamping position, before the workpiece 200 is required to be transferred from the transfer mechanism 300 to the processing platform 1, the fourth sensor 56 may detect whether an object is present in the clamping position, and if the fourth sensor 56 does not detect an object in the clamping position, the control system determines that the clamping device 2 is free of foreign objects 400, and the control system controls the first conveying device 4 and the second conveying device to transfer the workpiece 200 from the transfer mechanism 300 to the processing platform 1.

After the workpiece 200 is transferred to the processing platform 1, the fourth sensor 56 can detect whether the positioning piece 201 exists in the clamping position, if the fourth sensor 56 detects that the positioning piece 201 exists in the clamping position, the control system judges that the positioning piece 201 reaches the preset position, the control system controls the clamping device 2 to clamp the positioning piece 201, so that the workpiece 200 can be accurately positioned at the preset position, and then the processing equipment 100 processes the workpiece 200, so that the processing precision of the workpiece 200 can be ensured, and the qualification rate and quality of products can be improved.

The workbench 10 of the processing device 100 is provided with the fourth sensor 56, and the fourth sensor 56 can be used for detecting whether the foreign matters 400 exist in the clamping device 2 or not and detecting whether the positioning piece 201 in the clamping device 2 reaches the preset position or not, so that the workpiece 200 to be processed can be positioned at the preset position more stably and accurately, the processing precision of the workpiece 200 to be processed is ensured, and the qualification rate and quality of products are improved.

For example, the first driving mechanism 212 may be an air cylinder, the first clamping assembly 21 further includes a first transmission mechanism 215, one end of the first transmission mechanism 215 is connected to the first driving mechanism 212, the other end of the first transmission mechanism 215 is connected to the first movable clamping block 213, and the first driving mechanism 212 may be capable of driving the first transmission mechanism 215 to move so as to drive the first movable clamping block 213 to move.

The first clamping assembly 21 is arranged on the first base 211 through the first fixing block 214, so that the first driving mechanism 212 drives the first movable clamping block 213 to move, so as to clamp and position the positioning piece 201 at a preset position, and facilitate clamping and positioning the positioning piece 201. The fourth sensor 56 is arranged on the first fixing block 214, so that the fourth sensor 56 can be fixed relative to the first base 211, and inaccurate detection results of the fourth sensor 56 caused by shaking of the fourth sensor 56 can be prevented, and whether the clamping position of the first clamping assembly 21 has the positioning piece 201 or the foreign matter 400 can be detected more accurately by the fourth sensor 56.

For example, the clamping groove 2141 may be the clamping position described above.

For example, the clamping groove 2141 is formed as a V-groove, the first movable clamp block 213 is disposed obliquely, and the surface of the first movable clamp block 213 abutting against the positioning member 201 is not parallel to both surfaces of the V-groove. When the first movable clamping block 213 abuts the positioning member 201 in the clamping groove 2141, the positioning member 201 abuts against two surfaces of the clamping groove 2141, and at least one surface of the positioning member 201 and at least one surface of the first movable clamping block 213 abut against each other, so that the positioning member 201 can be positioned in the clamping groove 2141, and displacement of the positioning member 201 in the first direction (front-rear direction in reference to the figure) and the second direction (left-right direction in reference to the figure) is prevented, so that the positioning of the positioning member 201 is more accurate.

The first clamping assembly 21 is provided with the guiding groove 2111 on the first base 211, and the positioning groove 2141 is formed on the first fixing block 214, so that the first conveying device 4 can conveniently convey the workpiece 200 to a preset position. By arranging the fourth sensor 56 on the side wall of the slot 2141, it is convenient for the fourth sensor 56 to detect whether the slot 2141 has the positioning member 201, so that the fourth sensor 56 can more accurately detect whether the positioning member 201 reaches the slot 2141, and the fourth sensor 56 can more accurately detect whether the slot 2141 has the foreign matter 400.

The guide groove 32, the slit 226, the transition groove 2211 and the guide groove 2111 are arranged in a line along a first direction (referring to the front-rear direction in the figure), and the positioning member 201 may sequentially pass through the guide groove 32, the slit 226, the transition groove 2211 and the guide groove 2111 and finally enter the clamping groove 2141 during the process of transferring the workpiece 200 from the transfer mechanism 300 to a preset position on the processing platform 1. After the first clamping assembly 21 is closed, the positioning member 201 can be positioned in the clamping groove 2141 by the first movable clamping block 213 to position the workpiece 200 at a predetermined position.

According to the in-place detecting method of the workpiece 200 according to the embodiment of the third aspect of the present invention, the workpiece 200 is processed by the processing apparatus 100 according to the embodiment of the second aspect of the present invention, and the in-place detecting method of the workpiece 200 includes the steps of:

Transferring the to-be-machined piece 200 onto the machining platform 1;

Confirming that the to-be-machined piece 200 is at a preset position on the machining platform 1;

The in-place detection method of the to-be-machined workpiece 200 is characterized in that whether the to-be-machined workpiece 200 is provided with the preset number of positioning pieces 201 when the to-be-machined workpiece 200 passes through the guide device 3 is confirmed, when the control system detects that the number of times that the positioning pieces 201 pass through the guide device 3 is smaller than the number of the positioning pieces 201, the control system can judge that the positioning pieces 201 fall off from the to-be-machined workpiece 200, the to-be-machined workpiece 200 is abnormal, the control system controls the alarm device to give an alarm, such as a warning light or a warning bell, so as to remind an operator to treat the abnormal to-be-machined workpiece 200, and the clamping device 2 cannot clamp and position the to-be-machined workpiece 200 through clamping the positioning pieces 201, so that the to-be-machined workpiece 200 rotates during machining to reduce machining precision or discard the workpiece is prevented.

When the control system detects that the number of times the positioning member 201 passes through the guide 3 is equal to the preset number of positioning members 201, the control system may determine that the preset number of positioning members 201 are placed on the workpiece 200, so that the workpiece 200 with the preset number of positioning members 201 installed thereon may be transferred to the preset position.

After the workpiece 200 is transferred onto the processing platform 1, the in-place detection method of the workpiece 200 can determine whether the workpiece 200 is at a preset position on the processing platform 1 by detecting whether the second sensor 52 is in a triggered state. If the workpiece 200 is at the preset position on the processing platform 1, the workpiece 200 may trigger the second sensor 52, the second sensor 52 may transmit a detection signal to the control system, the control system determines that the workpiece 200 is at the preset position, and the control system may control the clamping device 2 to clamp the positioning member 201 so as to position the workpiece 200. Thereafter, the control system controls the processing device 100 to process the workpiece 200, so that the processing precision of the workpiece 200 can be improved, and the qualification rate and quality of products can be improved.

If the to-be-machined workpiece 200 is not located at the preset position on the machining platform 1, the second sensor 52 is in an un-triggered state, and the control system determines that the to-be-machined workpiece 200 is not located at the preset position, the control system does not close the control clamping device 2 or control the machining equipment 100 to machine the to-be-machined workpiece 200, so that the machining equipment 100 can be prevented from machining the to-be-machined workpiece 200 in an abnormal state.

According to the in-place detection method of the to-be-machined workpiece 200, by utilizing the processing equipment 100, whether the positioning pieces 201 on the to-be-machined workpiece 200 fall off or not can be detected, and after confirming that the to-be-machined workpiece 200 is provided with the preset number of positioning pieces 201 when conveyed through the guide device 3, the to-be-machined workpiece 200 is conveyed to the processing platform 1; after the workpiece 200 is transferred to the processing platform 1, the in-place detection method of the workpiece 200 can detect whether the workpiece 200 is at the preset position by using the processing device 100, and after confirming that the workpiece 200 is at the preset position on the processing platform 1, the processing device 100 starts to process the workpiece 200, so that the processing device 100 can be prevented from processing the workpiece 200 in an abnormal state, the processing precision of the workpiece 200 is ensured, and the qualification rate and quality of products are improved.

According to some embodiments of the present invention, the plurality of second sensors 52 are disposed on opposite sides of the clamping device 2 in a second direction (left-right direction in the drawing), the second direction (left-right direction in the drawing) is perpendicular to the first direction (front-rear direction in the drawing), the processing platform 1 has opposite first and second ends along the first direction, the guiding device 3 is disposed at the first end, the second sensor 52 is disposed at the second end, and it is confirmed that the workpiece 200 is at a predetermined position on the processing platform 1, including:

confirming that the second sensors 52 located on both sides of the clamping device 2 are triggered.

If the second sensors 52 at both sides of the clamping device 2 are triggered, it indicates that the workpiece 200 to be machined is at the preset position, and the control system controls the processing device 100 to process the workpiece 200, so that the processing precision of the workpiece 200 to be machined can be ensured, and the quality and qualification rate of the product can be improved.

If the second sensors 52 at both sides of the clamping device 2 are not completely triggered, it indicates that the workpiece 200 is in an abnormal state, for example, the workpiece 200 is skewed, the control system can control the alarm device to alarm, prompt the operator to process the workpiece 200 in the abnormal state in time, and after the second sensors 52 at both sides of the clamping device 2 are triggered, the control system controls the processing device 100 to process the workpiece 200, so that the processing device 100 can be prevented from processing the workpiece 200 in the abnormal state, the processing precision of the workpiece 200 is ensured, and the quality and qualification of the product are improved.

The workbench 10 can confirm whether the workpiece 200 is at the preset position on the processing platform 1 by detecting whether the second sensors 52 on two sides of the clamping device 2 are triggered or not through the plurality of second sensors 52, so that whether the workpiece 200 is at the preset position or not can be accurately detected, the workpiece 200 which is not at the preset position is prevented from being processed by the processing equipment 100, the processing precision of the workpiece 200 is ensured, the quality and the qualification rate of products are improved, and the production cost is reduced.

According to some embodiments of the present invention, transferring the workpiece 200 to be processed onto the processing platform 1 further comprises: the transfer time of the current workpiece 200 to be processed is detected in real time, and it is confirmed that the current transfer time is not greater than a preset time. For example, after the first sensor 51 detects that the first positioning member 201 passes through the guide slot 32, the first sensor 51 transmits a signal that the first sensor 51 passes through the guide slot 32 to the control system, the control system starts timing, and after the workpiece 200 is conveyed to the preset position, the second sensor 52 is triggered, the conveying time recorded by the control system is not longer than the preset time.

If the conveying time of the workpiece 200 is not longer than the preset time, the control system determines that the guide groove 32, the slit 226, the transition groove 2211, the guide groove 2111 and the clamping groove 2141 are free of the foreign objects 400, determines that the positioning member 201 is not separated, and then controls the clamping device 2 to clamp the positioning member 201, so that the workpiece 200 can be stably and accurately fixed at the preset position of the processing platform 1.

If the conveying time of the workpiece 200 is longer than the preset time, the control system determines that the workpiece 200 is blocked, and at least one of the guide groove 32, the slit 226, the transition groove 2211, the guide groove 2111 and the clamping groove 2141 has the foreign matter 400, or the control system determines that the positioning member 201 is detached, and the control system controls the alarm device to alarm, so as to remind the operator of timely handling the abnormal state, such as cleaning the processing platform 1. The control system confirms that the current conveying time is not longer than the preset time, the control system judges that no foreign object 400 exists in the guide groove 32, the clamping slot 226, the transition groove 2211, the guide groove 2111 and the clamping groove 2141, and the control system judges that the positioning piece 201 is normal, the control system controls the clamping device 2 to clamp the positioning piece 201, the control system controls the processing equipment 100 to process the workpiece 200, the processing precision of the workpiece 200 can be guaranteed, and the quality and the qualification rate of products are improved.

By detecting the conveying time of the current workpiece 200 in real time and confirming that the current conveying time is not greater than the preset time, whether the guide groove 32, the crack 226, the transition groove 2211, the guide groove 2111 and the clamping groove 2141 are provided with the foreign matters 400 can be accurately detected, so that the clamping device 2 can reliably clamp the positioning piece 201, the workpiece 200 can be reliably and accurately positioned at the preset position, the machining precision of the workpiece 200 can be ensured, and the quality and the qualification rate of products can be improved.

According to some embodiments of the present invention, after confirming that the workpiece 200 is at the preset position on the processing table 1 and before the processing apparatus 100 starts processing the workpiece 200, further comprising: it is confirmed that the distance between at least two places of the lower surface of the workpiece 200 and the upper surface of the processing table 1 is not more than a preset value.

If the second sensor 52 detects that the distance between at least two parts of the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is greater than the preset value, the control system determines that the surface of the workpiece 200 is uneven, and the control system controls the alarm device to alarm, so as to remind an operator to timely process the workpiece 200 with the uneven surface, for example, to replace the workpiece 200 with a new workpiece or clean the processing platform 1. If the second sensor 52 detects that the distance between at least two positions of the lower surface of the workpiece 200 and the upper surface of the processing platform 1 is not greater than the preset value, the control system controls the processing apparatus 100 to process the workpiece 200. Thus, the processing equipment 100 can be prevented from processing the to-be-processed workpiece 200 with uneven surface, the processing precision of the to-be-processed workpiece 200 is ensured, and the qualification rate and quality of products are improved.

According to some embodiments of the present invention, after the workpiece 200 is transferred onto the processing platform 1 and before the processing apparatus 100 starts processing the workpiece 200, the method further includes: it is confirmed whether the positioning member 201 on the workpiece 200 moves to a preset position in the holding device 2.

If the control system confirms that the positioning member 201 on the workpiece 200 has moved to the preset position in the clamping device 2, the control system controls the clamping device 2 to clamp the positioning member 201, and the control system controls the processing device 100 to process the workpiece 200. If the control system does not confirm that the positioning member 201 on the workpiece 200 has moved to a preset position in the clamping device 2, the clamping device 2 is not activated and the processing apparatus 100 does not process the workpiece 200. Therefore, the clamping device 2 can be prevented from being incapable of clamping the positioning piece 201, or the clamping device 2 can not be used for positioning the workpiece 200 to be processed at a preset position after the clamping device 2 clamps the positioning piece 201, so that the workpiece 200 to be processed in an abnormal state is prevented from being processed by the processing equipment 100, the processing precision of the workpiece 200 to be processed is improved, the quality of products is ensured, the qualification rate of the products is improved, and the production cost is reduced.

For example, during the production process, the control system may detect the workpiece 200 in real time by the second sensor 52 and the fourth sensor 56. After the at least one second sensor 52 is triggered, the control system starts to confirm whether the positioning member 201 on the workpiece 200 to be machined is moved to a preset position in the clamping device 2.

If the second sensors 52 on both sides of the clamping device 2 are triggered and the fourth sensor 56 senses that the positioning piece 201 is located in the preset position in the clamping device 2, the control system determines that the workpiece 200 reaches the preset position, and the control system controls the processing device 100 to process the workpiece 200. If the second sensors 52 on both sides of the clamping device 2 are triggered, the fourth sensor 56 does not sense that the positioning member 201 is located in the preset position in the clamping device 2; or at least one of the second sensors 52 on both sides of the clamping device 2 is not triggered, the fourth sensor 56 senses that the locating piece 201 is located in the preset position in the clamping device 2, and in the two conditions, the control system judges that the workpiece 200 to be processed is in an abnormal state, and the control system controls the alarm device to alarm so as to remind an operator of timely processing the abnormal state.

Therefore, the judgment precision of the control system can be improved, whether the to-be-machined workpiece 200 reaches the preset position can be detected more accurately, the to-be-machined workpiece 200 in the abnormal state is prevented from being machined by the machining equipment 100, the machining precision of the to-be-machined workpiece 200 is improved, the quality of products is ensured, the qualification rate of the products is improved, and the production cost is reduced.

According to some embodiments of the present invention, before confirming that the preset number of positioning members 201 are disposed on the workpiece 200, the in-place detection method of the workpiece 200 further includes: it was confirmed that the foreign matter 400 was not present in the holding device 2. For example, before the workpiece 200 is transferred from the transfer mechanism 300 to the processing platform 1, the control system controls the first clamping assembly 21 and the second clamping assembly 22 to be closed, and when the first clamping assembly 21 and the second clamping assembly 22 are in the closed state, if the first driving mechanism 212 is in the first preset stroke position and the second driving mechanism 222 is in the second preset stroke position, the control system determines that no foreign object 400 exists in the clamping device 2, and the control system controls the first conveying device 4 and the second conveying device to move so as to transfer the workpiece 200 from the transfer mechanism 300 to the preset position of the processing platform 1.

When the first clamping assembly 21 and the second clamping assembly 22 are in the closed state, if the first driving mechanism 212 is not at the first preset stroke position, it indicates that the foreign matter 400 exists in the first clamping assembly 21, if the second driving mechanism 222 is not at the second preset stroke position, it indicates that the foreign matter 400 exists in the second clamping assembly 22, and the control system controls the alarm device to alarm, so as to remind an operator to clean the first clamping assembly 21 and the second clamping assembly 22 in time.

After the operator cleans the foreign matters 400 in the first clamping assembly 21 and the second clamping assembly 22, the control system controls the first clamping assembly 21 and the second clamping assembly 22 to be closed, and after the control system determines that the foreign matters 400 are not in the clamping device 2, the control system controls the first conveying device 4 and the second conveying device to move so as to transfer the to-be-machined piece 200 from the transfer mechanism 300 to a preset position of the machining platform 1. Therefore, the workpiece 200 can be prevented from being unable to be conveyed to the preset position, the clamping device 2 can not clamp and position the positioning piece 201 due to the existence of the foreign matters 400, the clamping device 2 can reliably and accurately position the workpiece 200 to be at the preset position, the machining precision of the workpiece 200 is ensured, and the qualification rate and quality of products are improved.

For example, in some embodiments of the present invention, two positioning members 201 are provided on the workpiece 200, and when the workpiece 2 is at the preset position, one of the two positioning members 201 is located in the clamping groove 2141 of the first clamping assembly 21, and the other of the two positioning members 201 is located in the clamping slot 226 of the second clamping assembly 22. The control system may detect whether the foreign matter 100 is present in the gripping device 2 using the fourth sensor 56, the first position sensor 54 and the second position sensor 55 before the workpiece 200 is not transferred to the table 10; after the control system confirms that the gripping device 2 is free of foreign objects 400, the control system operates the second conveyor of the transfer mechanism 300 and the first conveyor 4 on the table 10 to transfer the workpiece 200 from the transfer mechanism 200 to the table 10.

During the process of transferring the workpiece 200 from the transfer mechanism 200 to the workbench 10, the control system can detect whether the number of times that the positioning member 201 passes through the guide groove 32 is equal to the preset number of times that the positioning member 201 passes through the guide groove 32 by using the first sensor 55, and if the control system confirms that no positioning member 201 falls off from the workpiece 200, the control system records the time that the positioning member 201 passes through the guide groove 32 and starts timing, and meanwhile, the control system controls the first conveying device 4 to continuously convey the workpiece 200.

During the transfer of the workpiece 200, after one of the two positioning members 201 is transferred into the chuck slot 2141, the workpiece 200 may stop moving under the restriction of the chuck slot 2141. At this time, the control system may detect whether the workpiece 200 is at the preset position using the second sensor 52, detect whether the positioning member 201 is at the preset position using the fourth sensor 56, and detect whether the surface of the workpiece 200 is flat using the second sensor 52 and the third sensor 53. If the control system determines that the workpiece 200 is at the preset position and the surface of the workpiece 200 is flat, the control system determines that the positioning piece 201 is at the preset position, and the control system controls the clamping device 2 to be closed so as to clamp the positioning piece 201 to position the workpiece 200 at the preset position.

In the process of conveying the workpiece 200 on the processing platform 1, if the second sensor 52 does not detect that the workpiece 200 is at the preset position, after the positioning member 200 passes through the guide groove 32, when the time recorded by the control system for conveying the workpiece 200 is greater than the preset time, the control system determines that at least one of the guide groove 32, the crack 226, the transition groove 2211, the guide groove 2111 and the clamping groove 2141 has the foreign matter 400, or the control system determines that the positioning member 201 falls off, and the control system controls the alarm device to alarm, so as to remind an operator to process an abnormal state in time, for example, clean the processing platform 1.

After the clamping device 2 is closed, the control system can detect the presence of the positioning member 201 in the clamping device 2 using the first position sensor 54 and the second position sensor 55. After the control system confirms that no positioning piece 201 falls off from the workpiece 200, the control system controls the processing mechanism 80 to process the workpiece 200. The in-place detection method of the to-be-machined workpiece 200 can prevent the machining equipment 100 from machining the to-be-machined workpiece 200 in an abnormal state, improve the production efficiency of a production line, ensure the machining precision of the to-be-machined workpiece 200 and improve the qualification rate and quality of products by detecting whether the positioning piece 201 falls off, detecting whether the positioning piece 201 and the to-be-machined workpiece 200 reach a preset position, detecting whether the foreign matter 400 exists in the clamping device 2, detecting the surface flatness of the to-be-machined workpiece 200 and detecting the time for the to-be-machined workpiece 200 to be conveyed on the machining platform 1 for multiple times.
