In the embodiment of the present application, the type of the carrier drive 32 is not particularly limited. For example, the carrier drive 32 may be, but is not limited to, a linear motor, an air cylinder, or the like. For example, the carrying driving member 32 may be a linear motor, the body carrying the driving member 32 is a stator portion of the linear motor, and the driving end of the carrying driving member 32 is a mover portion of the linear motor. The stator portion of the linear motor is fixedly connected with the main frame body 21, the rotor portion of the linear motor is slidably connected to the stator portion of the linear motor along the second direction, and the rotor portion of the linear motor is fixedly connected with the bearing table 31.

It is understood that the second direction is a straight direction that is staggered with respect to the first direction. In the embodiment of the present application, the second direction is not particularly limited. For example, the second direction may be the Y direction and the opposite direction as shown in fig. 2. Illustratively, the second direction may be a horizontal direction perpendicular to the first direction, and the second direction may be a longitudinal direction in a horizontal extending direction of the main frame 21.

It will be appreciated that the work surface 24 has first and second stations 26, 27 spaced apart along the second direction. The first station 26 and the second station 27 are each provided corresponding to the work port 25. The first photographing device 40 is disposed corresponding to the first station 26, and the second photographing device 50 is disposed corresponding to the second station 27. The carriage 31 is reciprocally movable between the first station 26 and the second station 27 by actuation of a carriage drive 32.

It can be understood that when the carrying table 31 carrying the part 10 to be measured is located at the first station 26, the photographing end of the first photographing device 40 corresponds to the first surface of the part 10 to be measured, and the first photographing device 40 may photograph an image of the first surface of the part 10 to be measured.

Referring to fig. 4 together, in the present embodiment, the appearance detecting apparatus 100 may further include a suction device 60. The suction means 60 may be connected to the main frame 21. The suction device 60 is spaced from the working surface 24 along the first direction, and is located at a side of the working surface 24 away from the second photographing device 50. The suction device 60 may be located at a position corresponding to the second station 27, and the suction device 60 may suck the part 10 to be measured. When the suction device 60 sucks the part to be measured 10, the first surface of the part to be measured 10 abuts against the suction device 60.

It can be understood that when the suction device 60 sucks the part 10 to be measured and there is no shielding object between the suction device 60 and the second photographing device 50, the photographing end of the second photographing device 50 corresponds to the second surface of the part 10 to be measured, and the second photographing device 50 may photograph an image of the second surface of the part 10 to be measured.

In the embodiment of the present application, the order in which the first and second face images of the test piece 10 are captured by the external inspection apparatus 100 is not particularly limited.

For example, the workpiece 10 may be moved by a device or a person to enter the accommodating groove and be accommodated in the accommodating groove, so that the carrier 31 carries the workpiece 10. The bearing driving piece 32 can drive the bearing table 31 to move to the first station 26, so that the to-be-tested piece 10 enters the first station 26; the first camera 40 may then take an image of the first side of the part 10 to be tested. The carrying table 31 carrying the part to be measured 10 may be located at the second station 27 or moved to the second station 27 by driving of the carrying driving member 32, so that the part to be measured 10 enters the second station 27. The suction device 60 can suck the to-be-tested piece 10 positioned in the accommodating groove, so that the to-be-tested piece 10 moves out of the accommodating groove; the carrying driving member 32 can drive the workpiece 10 to move out of the second station 27, so that the carrying table 31 is moved away from between the second photographing device 50 and the suction device 60, and the second photographing device 50 can photograph the second surface of the workpiece 10 through the working opening 25.

For another example, the suction device 60 may also directly suck the part 10 to be measured at the second station 27 through equipment or manpower when the carrying table 31 is not located at the second station 27, that is, there is no shielding between the second photographing device 50 and the suction device 60, and then the second photographing device 50 may photograph the second surface of the sucked part 10 to be measured. Subsequently, the carrying platform 31 can be moved to the second station 27, and the suction device 60 can contact the suction of the to-be-detected piece 10, so that the to-be-detected piece 10 enters the accommodating groove; the carrying driving member 32 can further drive the carrying table 31 and the to-be-measured member 10 carried by the carrying table 31 to move to the first station 26, and the first photographing device 40 can photograph the first surface of the to-be-measured member 10.

It can be understood that the appearance inspection apparatus 100 can be configured to photograph the first surface and the second surface of the part to be inspected 10 by respectively providing photographing devices on two opposite sides in the first direction, photographing the first surface of the part to be inspected 10 on the carrying table 31 by the first photographing device 40, and photographing the second surface of the part to be inspected 10 sucked by the suction device 60 by the second photographing device 50. Therefore, shooting of images on two sides of the to-be-detected piece 10 can be realized under the condition that the to-be-detected piece 10 is not turned over, the probability of appearance damage of the to-be-detected piece 10 during appearance detection can be reduced, and the qualification rate of products is improved.

In some embodiments, the appearance inspection device 100 may further include a transfer apparatus 70. The transfer device 70 may be mounted on the attachment frame 22, with the transfer device 70 being spaced from the work surface 24 in a first direction. The pipetting device 70 may include a first pipetting drive 71 and a second pipetting drive 72. The body of the first material moving driving member 71 is fixedly installed on the auxiliary frame body 22. The body of the second material moving driving member 72 is fixedly installed on the driving end of the first material moving driving member 71. The suction device 60 is fixedly mounted on the drive end of the second pipetting drive 72.

The first moving driving member 71 may drive the second moving driving member 72 to move in the third direction, and the second moving driving member 72 may drive the suction device 60 to move in the first direction.

It is understood that the third direction is a straight direction that is staggered with respect to the first direction and the second direction. In the embodiment of the present application, the third direction is not particularly limited. For example, the third direction may be the Z direction and its reverse direction as shown in fig. 2. For example, the third direction may be a horizontal direction perpendicular to the first direction and the second direction, the third direction may be a transverse direction of the horizontal extension direction of the auxiliary frame 22, and the first end and the second end of the auxiliary frame 22 may be two ends of the auxiliary frame 22 in the third direction.

It will be appreciated that the first transfer drive 71 may drive the second transfer drive 72 and the suction device 60 to move such that the suction device 60 is positioned at a location corresponding to the second station 27. The second material moving driving member 72 can drive the suction device 60 to approach the second station 27 when the suction device 60 corresponds to the second station 27, so that the suction device 60 can suck the part 10 to be tested located at the second station 27. When the position of the suction device 60 corresponds to the second station 27, and the suction device 60 sucks the part to be tested 10 located on the carrying table 31, the second material moving driving member 72 can drive the suction device 60 away from the carrying table 31, so as to reduce the blocking of the suction device 60 to the carrying table 31 moving along the second direction. The carrying platform 31 can be moved out of the second station 27, so that the photographing end of the second photographing device 50 corresponds to the second surface of the workpiece 10 to be measured, and at this time, the second photographing device 50 can photograph an image of the second surface of the workpiece 10 to be measured.

The first transfer drive 71 may also drive the second transfer drive 72 and suction device 60 to a position offset from the second station 27. The second material moving driving member 72 may drive the suction device 60 to approach the workpiece 10 when the suction device 60 corresponds to the external workpiece 10 (for example, when the suction device 60 is located at the first end of the attached frame 22), so that the suction device 60 can suck the external workpiece 10. Then the second material moving driving piece 72 drives the suction device 60 to reversely move, so that the heights of the suction device 60 and the piece 10 to be detected are increased; and the first material moving driving member 71 may drive the suction device 60 to move to a position corresponding to the second station 27. Then the second material moving driving member 72 can drive the to-be-measured member 10 to approach the second station 27 again; when the carrying table 31 is located at the second station 27, the suction device 60 can contact the suction of the part to be tested 10 near the second station 27, so that the part to be tested 10 enters the accommodating groove.

After the appearance inspection apparatus 100 finishes photographing the first surface and the second surface of the workpiece 10, the suction device 60 may suck the workpiece 10, the second material moving driving member 72 may drive the suction device 60 and the workpiece 10 to be far away from the working surface 24, and the first material moving driving member 71 may drive the suction device 60 and the workpiece 10 to be moved to a specified position (for example, the second end of the attaching frame 22) where the worker collects the workpiece 10. From this designated location, the worker may collect the part under test 10 for further inspection or processing of the part under test 10.

In the embodiment of the present application, the type of the first stock removal driving member 71 is not particularly limited. For example, the first material moving driving member 71 may be a linear motor, an air cylinder, or the like. The first material moving driving member 71 is a linear motor, the body of the first material moving driving member 71 is a stator portion of the linear motor, and the driving end of the first material moving driving member 71 is a mover portion of the linear motor.

In the embodiment of the present application, the type of the second material moving driver 72 is not particularly limited. For example, the second pipetting drive 72 may be a linear motor, an air cylinder, or the like. Illustratively, the second material moving driving member 72 is a cylinder, the body of the second material moving driving member 72 is a cylinder body of the cylinder, and the driving end of the second material moving driving member 72 is a piston rod of the cylinder.

In some embodiments, the hard piece 11 of the part under test 10 may generate a magnetic field. The suction device 60 may include a suction connection seat 61, a suction driving member 62, a ferromagnetic member 63, and a suction nozzle member 64. The suction connection seat 61 may be fixedly connected with the driving end of the second material moving driving member 72. The suction driving member 62 is fixedly installed on the suction connection seat 61. The ferromagnetic member 63 is fixedly connected to the driving end of the suction driving member 62. The suction connection seat 61 is provided with a connection groove, and the ferromagnetic piece 63 is at least partially accommodated in the connection groove and is slidingly connected with the connection groove along the first direction. The suction nozzle member 64 is fixedly mounted on the suction connection base 61.

The sucking driving part 62 is used for driving the ferromagnetic part 63 to move so that the ferromagnetic part 63 is close to or far from the hard part 11. When the ferromagnetic member 63 approaches the hard member 11 and abuts against the hard member 11, the ferromagnetic member 63 attracts the hard member 11 under the magnetic force. When the ferromagnetic member 63 is far away from the hard member 11, the hard member 11 cannot move synchronously with the ferromagnetic member 63 under the blocking of the suction connection seat 61, and the ferromagnetic member 63 can be separated from the hard member 11 under the driving of the suction driving member 62. The suction nozzle member 64 can suck the soft member 12 by the negative pressure of the air.

It will be appreciated that since the part under test 10 includes the hard part 11 and the soft part 12, and the hard part 11 can generate a magnetic field, that is, the hard part 11 has a magnetic property similar to that of a magnet, the hard part 11 and the soft part 12 can be attracted by the ferromagnetic part 63 and the suction nozzle part 64, respectively, thereby reducing the unstable suction or damage of the soft part 12 caused by sucking the hard part 11 and the soft part 12 by the same suction method.

It will be appreciated that the ferromagnetic member 63 may be a component made of ferromagnetic material. In the embodiments of the present application, the type of the ferromagnetic material is not particularly limited. For example, the ferromagnetic material may include an iron alloy or the like.

In the embodiment of the present application, the number of the nozzle members 64 is not particularly limited. For example, the number of the suction nozzle pieces 64 may be 2, two suction nozzle pieces 64 are disposed at intervals, and the two suction nozzle pieces 64 are used to suck the first component 121 and the second component 122, respectively.

Referring to fig. 5, in some embodiments, the receiving slots may include a first receiving slot 33 and a second receiving slot 34. The first receiving groove 33 may receive the hard member 11 and at least a portion of the first member 121, and the second receiving groove 34 may receive the second member 122. Wherein, the bottom wall of the second accommodating groove 34 is higher than the bottom wall of the first accommodating groove 33 in the first direction.

It can be appreciated that the height of the first member 121 in the first direction is smaller than the height of the second member 122 in the first direction, so that the difference between the bottom wall of the second receiving groove 34 and the bottom wall of the first receiving groove 33 can enable the first member 121 and the second member 122 to be stably received in the first receiving groove 33 and the second receiving groove 34, respectively, so as to reduce damage caused by excessive bending of the soft member 12 during appearance detection.

In the embodiment of the present application, the structure of the stage 31 is not particularly limited. For example, the carrier 31 may include a base 311 and a jig. The base 311 is movably disposed within the work port 25. The jig is fixedly installed on the base 311, and is located at a side of the base 311 facing the first photographing device 40. The jig may include a first bearing portion 312 and a second bearing portion 313. The first bearing portion 312 and the second bearing portion 313 are disposed at intervals. The first receiving groove 33 is disposed on the first bearing portion 312, and the second receiving groove 34 is disposed on the second bearing portion 313. The first accommodating groove 33 penetrates the first bearing portion 312 to face one side of the second bearing portion 313, and the second accommodating groove 34 penetrates the second bearing portion 313 to face one side of the first bearing portion 312.

With continued reference to fig. 2, in some embodiments, the appearance detection device may further include a shielding apparatus 80. The shielding device 80 may comprise a shielding member 81 and a shielding driver 82. The shutter 81 is movably provided on the work surface 24 in the second direction. The shutter 81 may block a part of the opening of the work port 25. The body of the shielding driving piece 82 is fixedly connected with the main frame body 21, and the driving end of the shielding driving piece 82 is fixedly connected with the shielding piece 81.

It can be appreciated that, when the suction device 60 is driven by the material moving device 70 to obtain the part to be tested 10 from the outside and move to the position corresponding to the second station 27, the shielding device 80 can be located at the second station 27 to shield the operation opening 25, so as to reduce the situation that the part to be tested 10 falls off from the suction device 60 due to accidents (such as power failure of the suction device 60, etc.) and is adjusted into the accommodating space 23 through the operation opening 25, thereby reducing the damage probability of the part to be tested 10 and the second photographing device 50. When the carrier 31 moves towards the second station 27, the shutter drive 82 can drive the shutter 81 to move in a direction away from the first and second stations 26, 27, thereby moving the shutter 81 out of the second station 27 to allow the carrier 31 to move into the second station 27. When the suction device 60 sucks the workpiece 10 and the carrying table 31 moves to the first station 26, that is, the second photographing device 50 photographs an image of the second surface of the workpiece 10, the shielding member 81 is maintained at a position far away from the second station 27, so that the second photographing device 50 can photograph an image of the second surface of the workpiece 10 through the operation opening 25.

It will be appreciated that in some cases, when the carrier 31 moves towards the second station 27, the shutter 81 may start to move away from the first station 26 and the second station 27 when the carrier 31 abuts, thereby reducing the space in which the working opening 25 is open during movement of the carrier 31 and the shutter 81, and reducing the likelihood that the part 10 to be measured will fall into the receiving space 23 during movement of the carrier 31 and the shutter 81.

In the embodiment of the present application, the type of the member to be measured 10 is not particularly limited. For example, the shutter 81 may be, but is not limited to, a baffle, an organ cover, or the like. Illustratively, the part 10 may be a blind slidably coupled to the work surface 24 via a rail.

The mount 41 may be fixedly mounted to the auxiliary frame 22 with the mount 41 being spaced apart from the first station 26 in the first direction. The movable seat 42 is movably disposed on the fixed frame 41 in the third direction. The adjusting member 43 is rotatably coupled to the fixed frame 41 and is screw-coupled to the movable seat 42. The body of the first driving member 45 is fixedly mounted on the movable seat 42, and the driving end of the first driving member 45 is fixedly connected with the first camera 44, and the lens end of the first camera 44 faces the first station 26. The first light source 46 is fixedly connected with the auxiliary frame 22.

The first driving member 45 may drive the first camera 44 to move in the first direction, so that the first camera 44 may be close to or away from the first station 26 and close to or away from the workpiece 10 located at the first station 26. The first camera 44 may take multiple pictures or multiple pieces of video during movement in the first direction.

Before the appearance inspection device 100 starts to operate, or after the appearance inspection device 100 operates for a long time, the first camera 44 may be misaligned in the first station 26, or may be affected by vibration of the environment in which the appearance inspection device 100 is located, so as to deviate from the first station 26, and at this time, a worker may rotate the adjusting member 43 to drive the movable seat 42 to move, so as to adjust the corresponding relationship between the first camera 44 and the first station 26, so that the first camera 44 may completely capture the first surface of the workpiece 10 to be inspected.

The first light source 46 may enhance the brightness of the first station 26 during the capturing of the part 10 to be tested by the first camera 44, thereby enhancing the sharpness of the image captured by the first camera 44.

In the embodiment of the present application, the type of the first driving member 45 is not particularly limited. For example, the first driving member 45 may be, but is not limited to, a cylinder, a linear motor, or the like. Illustratively, the first driving member 45 may be a cylinder, the body of the first driving member 45 may be a body of the cylinder, and the driving end of the first driving member 45 may be a piston rod of the cylinder.

The first annular light source 462 is fixedly connected to an end of the auxiliary frame 22 near the working surface 24. The first coaxial light source 461 is fixedly connected to the auxiliary frame 22. The first coaxial light source 461 is located between the first annular light source 462 and the first camera 44, and the first coaxial light source 461 is spaced apart from the first camera 44.

It can be appreciated that when the first camera 44 needs to photograph the workpiece 10, the first driving member 45 can drive the first camera 44 to approach and separate from the first coaxial light source 461, and the first camera 44 can photograph the workpiece 10 through the optical lens of the first coaxial light source 461 and the hollow space of the first annular light source 462.

Referring to fig. 2 and 8, in some embodiments, the second photographing device 50 may include a second camera 51, a second driving part 52, and a second light source 53. The body of the second driving piece 52 is fixedly connected with the main frame 21, the driving end of the second driving piece 52 is fixedly connected with the second camera 51, and the lens end of the second camera 51 faces the second station 27. The second light source 53 is fixedly connected to the main frame 21.

The second driving member 52 may drive the second camera 51 to move in the first direction so that the second camera 51 may be moved toward or away from the second station 27 and toward or away from the workpiece 10 located at the second station 27. The second camera 51 may take a plurality of pictures or a plurality of pieces of video during the movement in the first direction.

The second light source 53 can enhance the brightness of the second station 27 during the process of photographing the part 10 to be measured by the second camera 51, thereby enhancing the sharpness of the image photographed by the second camera 51.

In the embodiment of the present application, the type of the second driving member 52 is not particularly limited. For example, the second driver 52 may be, but is not limited to, a cylinder, a linear motor, or the like. Illustratively, the second driver 52 may be a cylinder, the body of the second driver 52 may be a block of the cylinder, and the driving end of the second driver 52 may be a piston rod of the cylinder.

In the embodiment of the present application, the type of the second camera 51 is not particularly limited. For example, the second camera 51 may be, but is not limited to, a CCD camera.

In the embodiment of the present application, the type of the second light source 53 is not particularly limited.

For example, the second light source 53 may be connected to the main frame 21 through a sliding rail, and the locking member 54 may be a locking mechanism of the sliding rail. The worker may lock the second light source 53 in a fixed position by pulling the locking member 54 in a forward direction, or may move the second light source 53 by pulling the locking member 54 in an opposite direction.

It will be appreciated that before the image of the part 10 to be measured is taken, the worker can move the second light source 53 in the first direction so that the second light source 53 is far away from the moving track of the shielding member 81 and the carrier plate, and the situation that the second light source 53 blocks the movement of the shielding member 81 and the carrier plate is reduced.

One implementation principle of the appearance detection device 100 of the embodiment of the present application is described in detail below with reference to fig. 1 to 8:

the first material moving driving member 71 drives the second material moving driving member 72 and the suction device 60 to move to the first end of the attached frame 22, and after the second material moving driving member 72 drives the suction device 60 to approach the external workpiece 10 to be detected, the suction device 60 sucks the workpiece 10 to be detected. The second material-moving driving member 72 then drives the suction device 60 that suctions the workpiece 10 to move, so that the suction device 60 is away from the work surface 24 in the first direction. The first material moving driving member 71 drives the second material moving driving member 72, the suction device 60 and the workpiece 10 to be tested to the position corresponding to the second station 27. In this case the shutter 81 may be located at the second station 27 and the carrier 31 may be located at the first station 26.

After the part to be measured 10 is moved to the position corresponding to the second station 27, the shutter 81 and the carrying table 31 are moved in the second direction, the shutter 81 is away from the first station 26, and the carrying table 31 is moved to the second station 27. Then, the second material moving driving member 72 can drive the sucking device 60 and the workpiece 10 to be tested to approach the second station 27, and after the workpiece 10 to be tested enters the accommodating groove, the sucking device 60 contacts the sucking device 10 to be tested, so that the workpiece 10 to be tested is accommodated in the accommodating groove, and the second material moving driving member 72 drives the sucking device 60 to be far away from the bearing table 31. Then, the carrier driving member 32 drives the carrier 31 and the workpiece 10 to move into the first station 26, and the first photographing device 40 photographs the first surface of the workpiece 10.

After the shooting of the first shooting device 40 is finished, the bearing driving piece 32 drives the bearing table 31 and the to-be-detected piece 10 to move into the second station 27, the second material moving driving piece 72 drives the sucking device 60 to be close to the to-be-detected piece 10 positioned at the second station 27, and the sucking device 60 sucks the to-be-detected piece 10; after the suction device 60 sucks the part to be tested 10, the second material moving driving member 72 drives the suction device 60 and the part to be tested 10 to be far away from the second station 27. The carrier 31 is then moved so that the station moves into the first station 26, reducing shadowing between the second camera 50 and the part 10 to be measured. The second photographing device 50 then photographs the second face of the part 10 to be measured. After the second photographing device 50 finishes photographing, the first material moving driving member 71 drives the second material moving driving member 72, the suction device 60 and the workpiece 10 to be measured to the second end of the attaching frame 22, and the worker can collect the workpiece 10 to be measured sucked by the suction device 60 from the position.

By the appearance inspection apparatus 100 provided by the embodiment of the present application, the first photographing device 40 and the second photographing device 50 may be respectively disposed at two sides in the first direction, so as to achieve photographing in the first surface and the second surface of the part to be inspected 10. When shooting the first surface, the to-be-measured piece 10 is borne on the bearing table 31, so that the first surface of the to-be-measured piece 10 is exposed; when the second surface is photographed, the suction device 60 sucks the test piece 10 from the first surface of the test piece 10, and exposes the second surface of the test piece 10. Thus, the appearance detection of the two sides of the to-be-detected piece 10 can be realized without turning the to-be-detected piece 10, and the damage probability of the to-be-detected piece 10 can be reduced.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The above-described embodiments of the application are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
