Referring to fig. 1, the present invention provides a detection device 10 and a carrier 100. The detecting device 10 includes a carrier 100, a driving mechanism 200, and a detecting mechanism 300.

The carrier 100 is used to position and clamp a workpiece to be tested. The driving mechanism 200 may be an electric cylinder, an air cylinder, or a motor screw nut set. The carrier 100 is fixedly disposed at a driving end of the driving mechanism 200 and can be driven by the driving mechanism 200 to move along a predetermined conveying direction, i.e. a horizontal direction shown in fig. 1. The inspection mechanism 300 is generally disposed on at least one side of the conveying path for inspecting the size and shape of the workpiece to be inspected. The detection mechanism 300 has a detection area, and the driving mechanism 200 can drive the carrier 100 to pass through the detection area, so as to detect the workpiece to be detected on the carrier 100.

Referring to fig. 2, the carrier 100 according to the preferred embodiment of the present invention includes a base plate 110, a positioning assembly 120 and a clamping assembly 130.

The bottom plate 110 is used for supporting and may have other shapes such as a rectangular shape. The bottom plate 110 is opened with a through groove 101, and the through groove 101 penetrates through the bottom plate 110. Furthermore, the inner wall of the through-groove 101 is provided with a plurality of supporting portions 111 for bearing the workpiece to be measured along the circumferential direction of the through-groove 101. The through groove 101 may be a groove of various shapes such as a rectangular groove, a circular groove, or the like, depending on the shape of the workpiece. The workpiece to be measured can be first placed in the through groove 101 and supported by the supporting portion 111. In general, the size of the through groove 101 is slightly larger than that of the workpiece to be measured, so that the workpiece to be measured can be placed in the through groove.

The support 111 may be a protruding block-like, rod-like structure. The contact area between the supporting portion 111 and the surface of the workpiece to be measured is small, so that the surface of the workpiece to be measured is shielded less. Specifically, in the present embodiment, the supporting portion 111 is a bump protruding toward the middle of the through groove 101, and a surface of the bump contacting the workpiece to be tested is a plane. Therefore, the supporting part 111 has a good supporting effect on the workpiece to be measured, and the flatness of the workpiece to be measured can be ensured.

The base plate 110 may be an integrally formed structure or may be formed by splicing a plurality of portions. The base plate 110 in this embodiment includes a carrier plate (not shown) and a support plate (not shown), the carrier plate is fixed on the upper surface of the support plate and is provided with a through groove 101, and the support plate is provided with a through hole corresponding to the through groove 101.

The positioning assembly 120 is disposed at an edge of the through slot 101 and can abut against a side surface of the workpiece to be measured supported by the supporting portion 111. The positioning assembly 120 can position the workpiece to be measured in the through groove 101 by abutting against the side surface of the workpiece to be measured.

Specifically, in the present embodiment, the positioning assembly 120 includes a first positioning element 121 and a second positioning element 122. The first positioning element 121 can abut against the side surface of the workpiece to be measured from the first direction, the second positioning element 122 can abut against the side surface of the workpiece to be measured from the second direction, and an included angle is formed between the first direction and the second direction. In this way, the positioning assembly 120 can position the workpiece to be measured from two different directions, so that the positioning accuracy is higher. Preferably, the first direction is perpendicular to the second direction, which can be the horizontal direction and the vertical direction shown in fig. 2, respectively.

The first positioning element 121 and the second positioning element 122 may be pin shafts, protrusions, etc. Specifically, in the present embodiment, the first positioning element 121 and the second positioning element 122 are both positioning pins. For the rectangular through groove 101, the first positioning element 121 may be two positioning pins disposed at the short edge of the through groove 101 at an interval, and the second positioning element 122 may be two positioning pins disposed at the long edge of the through groove 101 at an interval.

The clamping assembly 130 is mounted on the base plate 110, and the clamping assembly 130 can push the workpiece to be tested carried on the supporting portion 111 to move toward the positioning assembly 120 until the side surface of the workpiece to be tested abuts against the positioning assembly 120. Thus, the workpiece to be measured can be positioned within the range of the through groove 101.

The workpiece to be measured is positioned in the range of the through groove 101, which means that the orthographic projection of the workpiece to be measured on the plane of the bottom plate 110 falls into the area provided with the through groove 101. To ensure this, the first positioning element 121 and the second positioning element 122 are intended to be used in the region of abutment against the side of the workpiece to be measured, the orthographic projection of which on the plane of the base plate 110 should be at least partially within the region of the through slot 101.

Specifically, in this embodiment, the clamping assembly 130 includes a first clamping member 131 and a second clamping member 132, the first clamping member 131 can push the workpiece to be tested to abut against the first positioning member 121 along the first direction, and the second clamping member 132 can push the workpiece to be tested to abut against the second positioning member 122 along the second direction. Thus, the clamping assembly 130 and the positioning assembly 120 can clamp the workpiece to be tested from two directions, so that the clamping effect on the workpiece to be tested is better.

Specifically, in the present embodiment, the first clamping member 131 includes a first mounting plate 1311, a first abutting member 1312, and a first elastic member 1313. The first mounting plate 1311 is slidably disposed on the bottom plate 110 along a first direction, the first abutting member 1312 is disposed at one end of the first mounting plate 1311 close to the through slot 101, and the first elastic member 1313 provides an elastic pre-tightening force along the first direction for the first mounting plate 1311, so that the first abutting member 1312 is held in abutment with a workpiece to be tested.

Specifically, the first mounting plate 1311 may be coupled to the base plate 110 by a wire rail sliding structure, the wire rail may be fixed to an upper surface of the base plate 110, the wire rail may extend in a first direction, and a slider slidably coupled to the wire rail may be fixed to a surface of the first mounting plate 1311. The first abutting member 1312 is used for directly contacting with a side surface of the workpiece to be measured, and can be fixed to the first mounting plate 1311 in a threaded fastening manner. The first elastic member 1313 may be a spring, an elastic string, a tension spring, and the like, and in this embodiment, the first elastic member 1313 is a tension spring, one end of which is fixed to the first mounting plate 1311, and the other end of which is fixed to the base plate 110 and is stretched.

Under the action of the elastic pre-tightening force, the first abutting piece 1312 can elastically abut against the side face of the workpiece to be measured, so that the clamping effect on the workpiece to be measured is better. In addition, in the process of clamping the workpiece to be tested, only the elastic pretightening force of the first elastic piece 1313 is needed, and no additional acting force is needed.

Further, the second clamping member 132 includes a second mounting plate 1321, a second abutting member 1322, and a second elastic member 1323. The second mounting plate 1321 is slidably disposed on the bottom plate 110 along a second direction, the second abutting member 1322 is disposed at an end of the second mounting plate 1321 close to the through slot 101, and the second elastic member 1323 provides an elastic pre-tightening force along the second direction for the second mounting plate 1321, so that the second abutting member 1322 is held against the workpiece to be measured.

Specifically, the second clamping member 132 has a structure similar to that of the first clamping member 131. Moreover, the structure, installation manner and function of the second mounting plate 1321, the second abutting member 1322 and the second elastic member 1323 are substantially the same as those of the first mounting plate 1311, the first abutting member 1312 and the first elastic member 1313, and therefore, the description thereof is omitted.

In this embodiment, the clamping assembly 130 further includes a driver 133. The driving member 133 is used for driving the first abutting member 1312 to move away from the first positioning member 121, and driving the second abutting member 1322 to move away from the second positioning member 122.

As the first supporting member 1312 and the second supporting member 1322 are respectively far away from the first positioning member 121 and the second positioning member 122, the carrier 100 is opened, so as to facilitate loading and unloading of the workpiece to be tested. The degree of automation of the vehicle 100 can be improved by driving the driving member 133. In order to improve the consistency, the first propping element 1312 and the second propping element 1322 can move synchronously. Specifically, when the driving element 133 drives the first abutting element 1312 to move along the first direction, the first clamping element 131 can drive the second abutting element 1322 to move along the second direction. Or, when the driving element 133 drives the second abutting member 1322 to move along the second direction, the second clamping element 132 can drive the first abutting member 1322 to move along the first direction.

Further, in the present embodiment, the driving member 133 includes a power member 1331, a transmission member 1332 and a roller 1333. Wherein:

the power piece 1331 is fixed to the base plate 110. The power piece 1331 may be a motor, an air cylinder, or a motor screw pair structure. The driving member 1332 is fixedly connected to the first mounting plate 1311, and a guiding inclined surface (not shown) is disposed on the driving member 1332. The drive 1332 may be a metal plate-like structure that is movable with the first mounting plate 1311 in a first direction. The roller 1333 is rotatably mounted to the second mounting plate 1321 and is in rolling engagement with the guide ramp.

The power piece 1331 can drive the transmission piece 1332 to drive the first mounting plate 1311 away from the through slot 101 in a first direction, and the transmission piece 1332 forces the roller 1333 to roll along the guide slope to drive the second mounting plate 1321 away from the through slot 101 in a second direction. The guide slope extends in a direction between the first direction and the second direction. When the driving member 1332 moves in a first direction along with the first mounting plate 1311, the roller 1333 rolls along the guide slope, and thus the second mounting plate 1321 is driven to slide in a second direction. In this way, the synchronous movement of the first clamping member 131 and the second clamping member 132 can be achieved.

The power piece 1331 may be a cylinder, the moving end of which is not connected to the first mounting plate 1311, and when the cylinder is extended, the first mounting plate 1311 may be driven to slide away from the through groove 101 in a first direction. When the power element 1311 adopts a single-acting cylinder, the bottom plate 110 is further provided with the air distribution block 140, the air distribution block 140 is provided with an air inlet and a plurality of air outlets, and the air outlets are respectively communicated with the air inlet ends of the plurality of single-acting cylinders.

When the workpiece to be measured is positioned in the through groove 101, because the through groove 101 can expose both opposite surfaces of the workpiece to be measured, and the workpiece to be measured is supported by the plurality of supporting parts 111 in the through groove 101, the shielding of the surface of the workpiece to be measured is small. Therefore, when the carrier 100 moves to the detection area of the detection structure 300, the detection mechanism 300 can simultaneously detect the workpiece from both sides, thereby realizing full-scale detection of the workpiece.

In this embodiment, the detection area includes a first measurement area capable of scanning the surface profile of the workpiece to be measured and a second measurement area capable of photographing the surface of the workpiece to be measured, the first measurement area and the second measurement area are disposed at an interval in the conveying direction, and the driving mechanism 200 can drive the carrier 100 to sequentially pass through the first measurement area and the second measurement area.

In the first measurement area, parameters such as planeness, verticality or thickness of the workpiece to be measured can be measured by scanning the surface profile of the workpiece to be measured; in the second measuring area, the surface of the workpiece to be measured is photographed to measure the length, the width and other dimensions of the workpiece to be measured. Since the control system (not shown) takes longer to process the scanned contour information than it takes to process the photographed information. Therefore, the driving mechanism 200 drives the carrier 100 carrying the workpiece to be measured to pass through the first measurement region first and then pass through the second measurement region. So set up, when the work piece that awaits measuring is shooed in the second measurement area, control system can also parallel processing scanning's profile information to can promote detection efficiency effectively.

Specifically, the first measuring region and the second measuring region are respectively provided with a first measuring component 310 and a second measuring component 320, and both the first measuring component 310 and the second measuring component 320 can be installed on the vertical plate 330.

Referring to fig. 3 and 4, in the present embodiment, the first measuring device 310 includes a first 3D camera 311 and a second 3D camera 312, and the first 3D camera 311 and the second 3D camera 312 are disposed at an interval in a direction perpendicular to the conveying direction.

As shown in fig. 3, the first 3D camera 311 and the second 3D camera 312 are spaced apart from each other in the vertical direction and are disposed opposite to each other, and the first 3D camera 311 is located above the second 3D camera 312. When the carrier 100 passes through the first measurement area, the carrier 100 passes through between the first 3D camera 311 and the second 3D camera 312, and two surfaces of the workpiece thereon are exposed in the scanning ranges of the first 3D camera 311 and the second 3D camera 312, respectively, so that the first measurement component 310 can perform contour scanning on the workpiece on the carrier 100 from two sides.

Referring to fig. 5, the first 3D camera 311 includes a light emitting element 3111 and a lens 3112, the light emitting element 3111 irradiates the surface of the workpiece to be measured, and the workpiece to be measured reflects the light into the lens 3112, so that the surface of the workpiece to be measured can be clearly scanned. The second 3D camera 312 and the first 3D camera 311 may have the same structure, and therefore, the description thereof is omitted.

In some scenes, a workpiece to be detected has a flanging edge. As shown in fig. 6 and 7, the upper surface of the workpiece 20 to be measured is provided with a folded edge 21. When the light of the light emitting element 3111 irradiates the bottom surface close to the folded edge 21, the folded edge 21 blocks the part of the reflected light from being reflected into the lens 3112, so that the area cannot be collected by the first 3D camera 311, and the detection accuracy is affected.

In order to solve the above problem, in this embodiment, there are two first 3D cameras 311, two first 3D cameras 311 are disposed at intervals along the conveying direction, and the emergent light rays of the light emitting parts 3111 of the two first 3D cameras 311 intersect.

That is, the light emitted from the light emitting parts 3111 of the two first 3D cameras 311 can intersect. Therefore, when the light emitted from the light emitting part 3111 of one first 3D camera 311 to a certain region is blocked by the folded edge 21, and the lens 3112 cannot scan the contour of the region, the light emitting part 3111 of the other first 3D camera 311 may illuminate the region, and the reflected light is received by the lens 3112 of the other first 3D camera 311, so as to scan the contour. Therefore, the problem that the partial region of the workpiece 20 to be detected cannot be scanned due to shielding of the turned edge 21 is solved, and the detection precision is improved.

Of course, if the other side of the workpiece 20 to be measured, that is, the lower surface in the figure, is also formed with the burring 21, the two second 3D cameras 312 may be provided in the same manner as the two first 3D cameras 311.

Further, in the embodiment, the second measuring assembly 320 includes a third 3D camera 321 and a fourth 3D camera 322, and the third 3D camera 321 and the fourth 3D camera 322 are disposed at intervals along the conveying direction and at intervals in a direction perpendicular to the conveying direction.

When the carrier 100 passes through the second measurement area, the carrier 100 passes through between the third 3D camera 321 and the fourth 3D camera 322, so that the second measurement component 320 can photograph the workpiece to be measured on the carrier 100 from two sides. As shown in fig. 3, the third 3D camera 321 in the present embodiment is located in front of and below the fourth 3D camera 322. The carrier 100 may drive the workpiece to be measured to move to align with the third 3D camera 321, and the third 3D camera 321 photographs the lower surface, and the fourth 3D camera 322 photographs the upper surface. The third 3D camera 321 and the fourth 3D camera 322 may also integrate a light source (not shown), which may have a structure similar to that of the first 3D camera 311 and the second 3D camera 312.

Referring to fig. 1 and fig. 2 again, in the embodiment, the bottom plate 110 is provided with a plurality of through slots 101 spaced from each other along the conveying direction. The transport direction may be coincident with the first direction or the second direction, or may be a third different direction. Specifically, in the present embodiment, the conveying direction is the same as the first direction, i.e. the horizontal direction shown in fig. 1 and 2. Each through slot 101 is correspondingly provided with a positioning component 120 and a clamping component 130. Therefore, one workpiece to be tested can be positioned in each through slot 101, that is, a plurality of workpieces to be tested can be positioned and clamped on the carrier 100 at the same time.

Further, the center distance between two adjacent through slots 101 is equal to the center distance between the third 3D camera 321 and the fourth 3D camera 322 in the conveying direction.

The carrier 100 is driven by the driving mechanism 200 to drive a plurality of workpieces to be measured thereon to sequentially enter the second measurement area. Moreover, the center distance between two adjacent through slots 101, that is, the center distance between two adjacent workpieces to be measured, is equal to the center distance between the third 3D camera 321 and the fourth 3D camera 322. Therefore, when the previous workpiece to be measured is photographed by the fourth 3D camera 322, the next workpiece just comes to the third 3D camera 321 and is photographed by the third 3D camera 321. In this way, the detection efficiency of the detection device 10 can be significantly improved.

To further improve the photographing effect of the third 3D camera 321 and the fourth 3D camera 322, the second measuring assembly 320 further includes a first light source 323 and a second light source 324. The first light source 323 and the second light source 324 may be surface light sources or line light sources, and both may be independently controlled. The first light source 323 is disposed directly above the third 3D camera 321 and spaced apart from the third 3D camera 321, and the workpiece to be measured can pass through between the first light source 323 and the third 3D camera 321. The second light source 324 is disposed right below the fourth 3D camera 322 and spaced from the fourth 3D camera 322, and the workpiece to be measured can pass through between the second light source 424 and the fourth 3D camera 322. The first light source 323 and the second light source 324 can illuminate the workpiece to be measured, so that the obtained pictures are clearer.

Before the carrier 100 and the inspection apparatus 10 inspect the workpiece, the workpiece to be inspected may be loaded on the plurality of supporting portions 111, and the positioning assembly 120 and the clamping assembly 130 cooperate to position the workpiece to be inspected in the through groove 101. Because the through groove 101 can expose both opposite surfaces of the workpiece to be measured, and the workpiece to be measured is supported by the plurality of supporting parts 111 in the through groove 101, the shielding of the surface of the workpiece to be measured is small. Therefore, when the carrier 100 moves to the detection area, the detection mechanism 300 can simultaneously detect the workpiece to be detected from both sides. As can be seen, the carrier 100 and the inspection device 10 can meet the requirement of performing full-scale inspection on a workpiece.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
