The stage 10 is described in detail below.

Referring to fig. 2 to 4, the stage 10 includes a supporting member 11, a first positioning member 12 and a second positioning member 13.

The carrier 11 may be used for carrying the object 30 to be detected, and the carrier 11 may be a plate or a block made of a metal material (e.g. iron, aluminum, copper, alloy), a plastic material, wood, or the like. The carrier 11 may be fixedly connected or detachably connected to the support stand 20, for example, the carrier 11 may be welded to the support stand 20, and the carrier 11 may also be connected to the support stand 20 by bolts, screws, or other fasteners.

The object 30 to be detected may be a display screen panel, glass, or an element that needs to be processed or detected by an iron plate. Before the piece 30 to be detected is detected or processed, the piece 30 to be detected needs to be positioned and fixed on the bearing part 11, so that the piece 30 to be detected can be better detected.

Specifically, referring to fig. 5, the carrier 11 may include a first surface 113 and a second surface 114 opposite to each other, the first surface 113 is far away from the supporting platform 20 than the second surface 114, the first surface 113 may be used to carry at least one of the to-be-detected object 30, the first positioning element 12, the second positioning element 13, and the like, and the second surface 114 may contact with the supporting platform 20 or be spaced apart from the supporting platform 20. Of course, other components can be mounted on the first surface 113 and the second surface 114, and are not limited herein.

The first positioning member 12 is slidably connected to the carrier 11 such that the first positioning member 12 can slide in the first direction a relative to the carrier 11. Specifically, referring to fig. 3 and 4, the carrier 11 is provided with a connecting portion 111, the first positioning element 12 is provided with a matching portion 121, and the connecting portion 111 and the matching portion 121 can be matched with each other to enable the first positioning element 12 and the carrier 11 to be combined in a relatively sliding manner. For example, in one example, the connecting portion 111 can include a sliding slot 1111 and the mating portion 121 can include a guide 1211 that is mounted within the sliding slot 1111 such that the guide 1211 can slide within the sliding slot 1111. In another example, the connecting portion 111 may include a guide rail, and the engaging portion 121 may include a slide groove, and the guide rail is mounted in the slide groove such that the guide rail can slide in the slide groove. In yet another example, the connecting portion 111 may include a pulley, and the engaging portion 121 may include a sliding slot, wherein the pulley can slide in the sliding slot, so that the first positioning member 12 is slidably connected with the load bearing member 11. In yet another example, the connecting portion 111 may include a sliding slot, and the engaging portion 121 may include a pulley, which is capable of sliding in the sliding slot, so that the first positioning member 12 is slidably connected with the carrier member 11. Other ways of slidably connecting the first positioning element 12 to the carrier element 11 are within the scope of the present application and are not listed here.

The first positioning member 12 can abut against the member 30 to be detected, for example, the first positioning member 12 abuts against one or more surfaces of the member 30 to be detected, so as to position the member 30 to be detected. Meanwhile, the first positioning member 12 abuts against the member to be detected 30 to prevent the member to be detected 30 from moving when being detected.

The first positioning member 12 can directly abut against the member to be detected 30, for example, a side surface of the first positioning member 12 abuts against the member to be detected 30; the first positioning element 12 may not directly abut against the element 30 to be detected, for example, the second positioning element 13 may abut against the element 30 to be detected, and the first positioning element 12 abuts against the second positioning element 13.

The first positioning piece 12 can slide along the first direction a relative to the bearing piece 11, so that the pieces 30 to be detected with different sizes in the first direction a can be positioned by adjusting the relative positions of the first positioning piece 12 and the bearing piece 11, and the pieces 30 to be detected are not positioned by adopting a plurality of object stages with different sizes, thereby reducing the cost. The first direction a may be any direction, for example, the first direction a may be a front-back direction, a left-right direction, a front-right direction (for example, a 45 ° left oblique direction), a front-right direction, a left-right direction (for example, a 45 ° right oblique direction), or any other direction.

Further, the sliding of the first positioning member 12 on the carrier 11 has a certain sliding stroke, and the first positioning member 12 can slide in the sliding stroke relative to the carrier 11. After the first positioning member 12 slides relative to the carrier 11 and determines the position of the first positioning member 12, the first positioning member 12 needs to be fixed to avoid the relative sliding of the first positioning member 12 after the to-be-detected member 30 is positioned.

The object table 10 further comprises a first fastener 50, which first fastener 50 can be used to fix the first positioning element 12 in a plurality of positions within the sliding stroke of the carrier 11. The first fastening member 50 may be a screw, a bolt, a stud, etc., which are not enumerated herein.

It is understood that the carrier 11 may be provided with a plurality of positions for fixing the first positioning member 12, and the first positioning member 12 may be fixed at any one of the positions. The position to which the first positioning member 12 is fixed can be determined specifically according to the size of the member 30 to be detected. For example, a plurality of first fixing holes 112 with equal or unequal intervals may be formed in the carrier 11, and the first positioning member 12 may be fixed on the carrier 11 by locking the first fastening member 50 in any one of the first fixing holes 112.

Further, referring to fig. 3 and 4, the first positioning element 12 may be provided with a first slot 122 extending along the first direction a, and the first fastening element 50 may pass through the first slot 122 and be locked in the first fixing hole 112. The first fastening member 50 can be tightly locked in the first fixing hole 112, the first fastening member 50 can be loosely locked in the first fixing hole 112, and the first fastening member 50 can be not locked in the first fixing hole 112. The tight locking means that the first fastening member 50 is locked in the first fixing hole 112, and the first fastening member 50 tightly abuts against the first positioning member 12. The loose locking means that the first fastening member 50 is not locked in the first fixing hole 112, and the first fastening member 50 does not abut against the first positioning member 12.

Specifically, the first groove 122 is a strip-shaped groove having a certain length, the cross-sectional shape of the first groove 122 along the perpendicular first direction a may be a step shape or other shape, and the first groove 122 penetrates through the first positioning member 12, so that the first fastening member 50 can fasten any position of the first groove 122.

When the first fastening member 50 is tightly locked in the first fixing hole 112, the first fastening member 50 abuts against the first positioning member 12, and the first positioning member 12 is fastened on the carrier 11 by the first fastening member 50, at this time, the first positioning member 12 cannot slide relative to the carrier 11. When the first fastening member 50 is loosely locked or unlocked in the first fixing hole 112, the first fastening member 50 does not abut against the first positioning member 12, and the first positioning member 12 can slide along the first direction a. For example, the maximum distance that the first positioning member 12 can slide along the first direction a when the first fastening member 50 is loosely locked in the first fixing hole 112 can be the length of the first slot 122; when the first fastening member 50 is not locked in the first fixing hole 112, the maximum sliding distance of the first positioning member 12 in the first direction a may be the length of the connecting portion 111, so that the position of the first positioning member 12 may be finely adjusted to better position the member 30 to be detected.

After the relative position between the first positioning member 12 and the carrier member 11 is adjusted, the first positioning member 12 may be fixed to the carrier member 11 by the first fastening member 50. After the object 30 to be detected is placed on the carrier 11, if the size of the object 30 to be detected in the first direction a is shorter or longer, or if the size difference between the new object 30 to be detected and the previous object 30 to be detected in the first direction a is smaller, the first fastening member 50 can be loosened, then the first positioning member 12 can be slid in the first direction a, the position of the first positioning member 12 can be adjusted, and the first fastening member 50 can be tightly locked in the first fixing hole 112 after the position of the first positioning member 12 is determined. Therefore, when the size difference of the different pieces 30 to be detected in the first direction A is small, or when the initial positioning of the pieces 30 to be detected is inaccurate, the pieces 30 to be detected can be more quickly positioned, the operation is simple, and the working efficiency is high.

In the embodiment shown in fig. 3, the first positioning member 12 is provided with two first grooves 122, the two first grooves 122 are respectively distributed on two sides of the matching portion 121, the carrier 11 is provided with a plurality of first fixing holes 112, and the plurality of first fixing holes 112 are symmetrically and equally spaced on two sides of the connecting portion 111, so that the first positioning member 12 can be more stably fixed on the carrier 11 by two or more first fastening members 50, and the first positioning member 12 is not easy to rotate or slide. In the embodiment shown in fig. 3, the number of the first fastening members 50 is two, and the first fastening members are respectively inserted into the two first grooves 122.

In another example, the first positioning member 12 may be provided with a fixing hole (not labeled), and the first fastening member 50 passes through the fixing hole of the first positioning member 12 and the first fixing hole 112 to fix the first positioning member 12 to the carrier member 11.

Referring to fig. 3, the first positioning element 12 is T-shaped, so that the abutting area between the first positioning element 12 and the to-be-detected element 30 or the second positioning element 13 can be increased, and the first positioning element 12 can better position the to-be-detected element 30.

Referring to fig. 2 to 4, the second positioning element 13 is slidably mounted on the supporting element 11. For example, the second positioning member 13 may be slidably connected to the first positioning member 12, so that the second positioning member 13 is indirectly slidably mounted on the carrier 11. Alternatively, the second positioning member 13 may be directly slidably connected to the carrier 11.

The second positioning member 13 is slidable relative to the first positioning member 12 in a second direction B different from the first direction a. It is understood that the second direction B may be any direction different from the first direction a. For example, the second direction B may be front-back, left-right, left-front-right-back (e.g., left-oblique 45 ° direction), right-front-left-back (e.g., right-oblique 45 ° direction), or any other direction different from the first direction a. For example, when the first direction a is front-rear, the second direction B may be left-right. Thus, one object stage 10 can position the object 30 to be detected with different sizes in the first direction a, and can also position the object 30 to be detected with different sizes in the second direction B.

Further, the second direction B and the first direction a may form a predetermined included angle. The preset included angle may be a preset included angle, for example, the preset included angle may be 15 °, 30 °, 45 °, 60 °, 90 °, 120 °, 150 °, and the like, so that the to-be-detected object 30 may be supported on the supporting member 11 in a predetermined posture. The preset included angle can be determined according to the shape of the piece to be detected 30, so that the object stage 10 can better position the piece to be detected 30, for example, when the included angle between two adjacent sides of the piece to be detected 30 is 30 degrees, the preset included angle is 30 degrees; when the included angle between the two adjacent sides of the piece 30 to be detected is 90 degrees, the preset included angle is 90 degrees.

In the embodiment shown in fig. 3, since the object 30 to be detected is shaped as a rectangular parallelepiped, the preset angle between the first direction a and the second direction B is 90 °.

Referring to fig. 2 and 3, the second positioning element 13 and the first positioning element 12 may jointly define a positioning space 40, and the object 30 to be detected may be placed in the positioning space 40, so that the object 30 to be detected may be carried on the carrier 11 in a predetermined posture. Therefore, on one hand, the detection or processing of the piece to be detected 30 can be facilitated; on the other hand, when a defect is detected, the specific position of the defect on the member to be detected 30 can be determined more accurately. The predetermined posture may be a preset posture, for example, the predetermined posture may be a posture in which the long side of the to-be-detected piece 30 is parallel to the long side of the bearing 11, and the short side of the to-be-detected piece 30 is parallel to the short side of the bearing 11. The preset posture can also be a posture in which the long side of the piece to be detected 30 and the bearing piece 11 are at a certain angle, and the short side of the piece to be detected 30 and the short side of the bearing piece 11 are at a certain angle, other conditions of the preset posture are not listed one by one, and the preset posture is set only by meeting the pose requirement that the detection jig 100 detects the piece to be detected 30.

Further, the second positioning member 13 can abut against the member to be detected 30 located in the positioning space 40 to position the member to be detected 30. When the first positioning member 12 slides relative to the carrier member 11, the size of the positioning space 40 in the first direction a will change. When the second positioning member 13 slides relative to the carrier 11, the dimension of the positioning space 40 in the second direction B will change. When the first positioning member 12 and the second positioning member 13 both slide relative to the carrier 11, the dimension of the positioning space 40 in the first direction a and the dimension of the positioning space in the second direction B are changed. Thus, by sliding the first positioning member 12 and/or the second positioning member 13, the stage 10 can position the objects 30 to be detected with different sizes.

Specifically, referring to fig. 3 and 4, the second positioning element 13 includes a first arm 131 and a second arm 132. The first arm 131 and the second arm 132 may be fixedly connected so as to fit the piece 30 to be detected at a fixed angle. The first arm 131 and the second arm 132 may also be connected in a rotatable manner, that is, the second arm 132 may rotate relative to the first arm 131 to change the included angle between the second arm 132 and the first arm 131, so that the object table 10 can position the object 30 to be detected with different included angles. The first arm 131 may abut against the member to be detected 30, the first arm 131 may not abut against the member to be detected 30, and the second arm 132 may abut against the member to be detected 30.

Further, the first arm 131 may be connected to the second arm 132 in an L-shape. That is, the angle between the first arm 131 and the second arm 132 is 90 degrees, so as to position the object 30 to be detected whose angle is a right angle (for example, the object 30 to be detected whose planar shape is a right triangle, a rectangle, a square, or the like).

Referring to fig. 3 to 5, the first positioning element 12 is provided with a second groove 123 extending along the second direction B, and the first arm 131 penetrates through the second groove 123 and can slide along the second groove 123. When the first arm 131 slides in the second slot 123, the second positioning member 13 slides in the second direction B relative to the first positioning member 12. The second groove 123 may be opened at any position on the first positioning member 12, for example, the second groove 123 may be opened at a side of the first positioning member 12 away from the member 30 to be detected, the second groove 123 may also be opened at a side of the first positioning member 12 close to the member 30 to be detected, and the second groove 123 may also be opened in the middle of the first positioning member 12.

In one example, the second groove 123 is a groove with three open sides (as shown in fig. 4), including two sides of the first positioning member 12 along the second direction B and one side of the first positioning member 12 near the member to be detected 30. The first arm 131 comprises a first positioning surface 1311, the first positioning surface 1311 being flush with a side surface of the first positioning element 12 or protruding with respect to the side surface of the first positioning element 12 for abutting against the first edge 31 of the element 30 to be detected.

The first edge 31 refers to an edge of the to-be-detected piece 30 close to the first positioning piece 12 in the first direction a, the first positioning surface 1311 refers to a side surface of the first arm 131 close to the to-be-detected piece 30, and the side surface of the first positioning piece 12 refers to a surface of the first positioning piece 12 close to the to-be-detected piece 30. It will be appreciated that the first arm 131 now abuts against the first edge 31 or the first arm 131 together with the first positioning element 12 abuts against the first edge 31 to position the first edge 31.

In another example, the second groove 123 is a groove with two open sides, and the two sides include two sides of the first positioning member 12 along the second direction B. It can be understood that, in the embodiment, after the first arm 131 extends into the second groove 123, a portion of the first arm 131 extending into the second groove 123 does not expose the first positioning member 12 in the first direction a, and the first arm 131 cannot position the first edge 31 of the to-be-detected piece 30, at this time, the first edge 31 of the to-be-detected piece 30 can be positioned by the side surface of the first positioning member 12, that is, the first edge 31 is positioned by the first positioning member 12.

Further, referring to fig. 3 and 4, the object stage 10 may further include a second fastener 60, and the second fastener 60 may be a bolt, a screw, a stud, or other fasteners. The first arm 131 is formed with a plurality of connecting holes 1312, the first positioning member 12 is formed with a third slot 124, and the second fastening member 60 can pass through the third slot 124 and any one of the connecting holes 1312 to fix the first arm 131 on the first positioning member 12, thereby fixing the second positioning member 13 on the first positioning member 12. The second fastening member 60 passes through the third slot 124 and then is locked in the connecting hole 1312, and the second fastening member 60 abuts against the first positioning member 12, so that the second positioning member 13 can be fixed on the first positioning member 12.

In one example, at least two second fastening members 60 are inserted into the third slots 124 and the corresponding connecting holes 1312 to fix the second positioning member 13 to the first positioning member 12, so that the connection between the second positioning member 13 and the first positioning member 12 is tighter, and the second positioning member 13 is not easy to rotate relative to the first positioning member 12.

Further, the third groove 124 may be a strip-shaped through groove extending along the second direction B, and when the second fastening member 60 does not interfere with the first positioning member 12, the second positioning member 13 may be slid along the second direction B relative to the first positioning member 12 by applying a pushing force to the second positioning member 13, so that the size of the positioning space 40 in the second direction B may be adjusted to be smaller, and the member 30 to be detected may be better loaded on the bearing member 11 in a predetermined posture. Therefore, when the position of the second positioning element 13 needs to be finely adjusted, the second positioning element 13 can be pushed to slide along the second direction B by loosening the second fastening element 60, and the second fastening element 60 is tightened after the position of the second positioning element 13 is determined, so as to fix the second positioning element 13 on the first positioning element 12. It is understood that the second fastener 60 may move within the third slot 124.

In an embodiment, the first positioning element 12 and the first arm 131 may be connected by a plurality of connecting holes 1312 formed in the first arm 131, at least one mounting hole (not shown) may be formed in the first positioning element 12, and the second fastening element 60 passes through the mounting hole and the connecting hole 1312 to fixedly connect the first arm 131 to the first positioning element 12, so as to fix the second positioning element 13 to the first positioning element 12.

In another embodiment, the connection relationship among the supporting member 11, the first positioning member 12, and the first arm 131 may further include a plurality of connection holes 1312 formed in the first arm 131, a third slot 124 formed in the first positioning member 12, or at least one mounting hole (not shown), a second fixing hole (not shown) formed in the supporting member 11, and a second fastening member 60 passing through the mounting hole or the third slot 124, the connection hole 1312, and the second fixing hole to fixedly connect the supporting member 11, the first positioning member 12, and the second positioning member 13 together. The second fixing hole may be the same as the first fixing hole 112, for example, when the second fixing hole is the same as the first fixing hole 112, the second fixing hole is the same as the first fixing hole 112.

Referring to fig. 3 and fig. 4, the second arm 132 includes a second positioning surface 1321, the second positioning surface 1321 is used for abutting against the second edge 32 of the object 30 to be detected, and the second edge 32 and the first edge 31 are two connected edges of the object 30 to be detected. The second edge 32 is an edge of the to-be-detected piece 30 close to the second arm 132 in the second direction B, the second positioning surface 1321 is a surface of the second arm 132 close to the to-be-detected piece 30, and the second arm 132 is used for positioning the second edge 32. When the first arm 131 slides along the second groove 123, the second arm 132 slides relative to the carrier 11 along with the sliding of the first arm 131, so as to adjust the dimension of the positioning space 40 in the second direction B.

In one example, the second arm 132 and the first arm 131 may be a single piece, that is, the second positioning member 13 is integrally formed and not formed by subsequent assembly, so that the first arm 131 and the second arm 132 are more stable and have less error in positioning.

In another example, the second arm 132 and the first arm 131 may be separate bodies, and when the second arm 132 is rotatably connected to the first arm 131, the second arm 132 may be fixed to the carrier 11 or the second arm 132 may be fixed to the first arm 131 after the position of the second arm 132 is determined. For example, a hole is formed in the second arm 132, a hole is formed in the carrier 11, and a fastener is inserted through the hole in the second arm 132 and the hole in the carrier 11, so that the second arm 132 is fixedly connected to the carrier 11. Or, the joint of the first arm 131 and the second arm 132 is provided with a hole, and a fastener is inserted into the hole of the joint to fasten the first arm 131 and the second arm 132 together, so that the second arm 132 can rotate relative to the first arm 131 after the fastener is loosened.

In some embodiments, when the second positioning member 13 slides relative to the carrier 11, at least a portion of the second positioning member 13 may protrude out of the carrier 11, so as to be used for positioning the to-be-detected member 30 having a size larger than that of the carrier 11 in the second direction B. Specifically, when the first arm 131 slides in the second groove 123, the second arm 132 may extend out of the carrier 11, and the second arm 132 may position the object 30 to be detected, which is larger in size than the carrier 11. Therefore, when the size of the object 30 to be detected is larger than that of the carrier 11, the carrier 11 or the stage 10 does not need to be replaced, and the working efficiency is improved.

Referring to fig. 2, 4 and 5, the stage 10 may further include a fixing member 14, and the fixing member 14 is mounted on the supporting member 11 and is used for fixing the object 30 to be detected on a side of the first surface 113 of the supporting member 11. The first positioning member 12 and the second positioning member 13 are mounted on the first surface 113. In this way, the to-be-detected member 30 can be well fixed on the supporting member 11 through the fixing member 14, so as to avoid the to-be-detected member 30 from sliding relative to the supporting member 11 to affect the detection result or the processing result when the to-be-detected member 30 is detected or processed.

The fixing part 14 may include a suction cup, by which the to-be-detected part 30 can be sucked, so that on one hand, damage to the to-be-detected part 30 can be avoided; on the other hand, the clamping and releasing of the suction force are easy to control, so that the to-be-detected piece 30 is convenient to disassemble and assemble. When the member 30 to be detected is made of a metal material, the fixing member 14 may be a magnet, and the member 30 to be detected may be attracted by the magnet. The fixing member 14 may also be a latch provided on the carrier 11, and the to-be-detected member 30 may be latched on the carrier 11. Of course, the fixing member 14 may be other elements having a fixing function, and is not limited herein.

When the piece 30 to be detected is fixed on the first surface 113, the piece 30 to be detected may be attached to the first surface 113, and the piece 30 to be detected may also be spaced from the first surface 113.

The fixing member 14 may protrude from the first surface 113 of the carrier 11, may be flush with the first surface 113, or may be lower than the first surface 113, which is not limited herein. The fixing member 14 may be fixedly mounted on the carrier 11 by means of a fastener (e.g., a screw, etc.) or the like. The number of the fixing member 14 may be one or more.

Further, the carrier 11 is provided with a through hole 115, and the fixing member 14 is mounted in the through hole 115. The fixing member 14 may be expanded to be engaged in the through hole 115 to be fixedly mounted on the carrier 11, and the fixing member 14 may be fixed in the through hole 115 by other methods, which are not limited herein. The through hole 115 is shaped as a strip with a certain length, and the fixing member 14 can slide in the through hole 115 to change the installation position of the fixing member 14, so as to fix the to-be-detected members 30 with different positions and sizes.

Specifically, in one example, the cross-sectional shape of the cross-section of the through-hole 115 perpendicular to the first face 113 is a step shape, the fixing member 14 is mounted on the step in the through-hole 115, and the fixing member 14 can slide on the step to change the mounting position of the fixing member 14, as shown in fig. 2. In another example, a sliding groove is formed in the through hole 115, and a guide rail is formed on the fixing member 14, so that the fixing member 14 can slide in the sliding groove to change the installation position of the fixing member 14. In another example, a guide rail is disposed in the through hole 115, a sliding groove is disposed on the fixing member 14, and the fixing member 14 can slide on the guide rail to change the installation position of the fixing member 14.

Further, the number of the fixing members 14 is plural, and correspondingly, the number of the through holes 115 is plural, for example, the number of the fixing members 14 may be 2, 3, 4, 5, 6, 7 or more. The number of through holes 115 may be 2, 3, 4, 5, 6, 7 or more. The number of the fixing members 14 may be equal to the number of the through holes 115, or the number of the fixing members 14 may be greater than the number of the through holes 115, and one or more fixing members 14 may be correspondingly installed in each through hole 115. In one implementation, a plurality of fasteners 14 are in one-to-one correspondence with a plurality of through holes 115, with each fastener 14 being mounted within a corresponding through hole 115. The mounting position of the fixing member 14 in one through hole 115 may be the same as or different from the mounting position in the other through hole 115. The through holes 115 may be uniformly distributed on the carrier 11, and the through holes 115 may be randomly distributed on the carrier 11.

In the embodiment shown in fig. 2 and 4, the number of the fixing members 14 is four, the number of the through holes 115 is four, and one fixing member 14 is installed in each through hole 115. Four through holes 115 are provided around the mounting center on the carrier 11, and the distances between the four fixing pieces 14 and the mounting center may be equal or unequal. The mounting position of each fixing member 14 in the corresponding through hole 115 can be adjusted according to the size of the member 30 to be detected, so as to better fix the member 30 to be detected.

Further, referring to fig. 2 and 4, the stage 10 further includes a suction member (not shown), which is disposed on a side of the second surface 114 of the supporting member 11 and connected to the fixing member 14, and the suction member can draw air in the fixing member 14, so that the fixing member 14 can suck the object 30 to be detected under the negative pressure. In this way, the fixing member 14 can be fixed more firmly on the side of the first surface 113 of the carrier 11 by the air-extracting member.

The air extracting part may be, without limitation, an air extractor, an air pump, or other elements capable of extracting air. The air-extracting member is disposed on the second surface 114, so that the bearing area of the first surface 113 of the bearing member 11 can be increased, and the influence of the air-extracting member on the member 30 to be detected can be avoided.

Specifically, the fixing member 14 may further include an air cylinder, the suction cup is communicated with the air cylinder, the air pumping member may be connected with the air cylinder through an air pipe, and the air pumping member may also be directly connected with the air cylinder. The air-extracting member can extract air in the air cylinder, so that the suction cup of the fixing member 14 can suck the member to be detected 30 by vacuum suction force. The power of the air extracting member can be adjusted according to the volume and the weight of the member 30 to be detected, so as to better adsorb the member 30 to be detected.

Further, referring to fig. 2, fig. 4 and fig. 5, the stage 10 further includes a sensor 15, the sensor 15 is mounted on the supporting member 11, and the sensor 15 can detect whether the object 30 to be detected is placed on the supporting member 11.

In particular, the sensor 15 may be a pressure sensor, a distance sensor, a light sensor, or the like, not to mention here. The sensor 15 may be mounted on the first surface 113 of the carrier 11, the sensor 15 may also be mounted on the second surface 114 of the carrier 11, and the sensor 15 may also be embedded in the carrier 11.

In the embodiment shown in fig. 2 and 4, a mounting groove is formed on the carrier 11, and the sensor 15 is mounted in the mounting groove. Further, a plurality of through-holes 115 encircle the center evenly distributed of mounting groove, so, sensor 15 can detect more accurately that has placed on bearing piece 11 and has detected piece 30.

Further, the sensor 15 can be electrically connected with the air extracting part, when the sensor 15 detects that the piece 30 to be detected is placed on the bearing part 11, the sensor 15 can send an air extracting signal to the air extracting part, and the air extracting part starts air extraction after receiving the air extracting signal; alternatively, when the air extractor finds that the data of the sensor 15 is greater than the set threshold, the air extractor starts to extract air.

In one embodiment, the sensor 15 is a light sensor, which continuously emits light outwards, and determines whether the member to be detected 30 is placed on the supporting member 11 according to the intensity of the received light reflected back to the light sensor. It can be understood that, if the piece 30 to be detected is carried on the bearing piece 11, light rays will be reflected back to the light ray sensor by the piece 30 to be detected after striking the piece 30 to be detected, and because the piece 30 to be detected is closer to the light ray sensor, the intensity of the light rays received by the light ray sensor is stronger at the moment; if the object 30 to be detected is not carried on the carrier 11, the emitting distance of the light will be long until the light hits another object and can be reflected back to the light sensor, at which time the light intensity received by the light sensor is weak or even no laser light is received.
