[0037] An embodiment of the utility model provides an object conveying device, which includes a base 1, a conveying tray 2, a transport mechanism 3, a detection mechanism, a screening and conveying mechanism and a driving mechanism 6. The transport mechanism 3 is used to transport objects on the workstation to a selected position. The detection mechanism is used to detect the type of the object, and the type includes at least a first category and a second category. The products of the first category and the second category may be different in structure, material or production batch number. It is understandable that in other embodiments, other types of products may also be included, such as the third category or the fourth category. The screening and conveying mechanism includes a first track 4 and a second track 5, the first track 4 is used to convey the first category of objects, and the second track 5 is used to convey the second category of objects. The driving mechanism 6 is used to drive at least one of the first track 4 and the second track 5 to move, so that the object entrance of the first track 4 or the second track 5 is located on the moving path of the object conveyed by the transport mechanism 3.

[0038] The driving mechanism 6 is used to locate the entrance of the first track 4 for conveying the first category of objects or the second track 5 for conveying the second category of objects on the moving path of the objects conveyed by the transport mechanism 3, so that the entrances of the first track 4 and the second track 5 can be arranged in a way that their projections on the horizontal plane at least partially overlap, thereby reducing the occupied area when arranging the first track 4 and the second track 5 or more tracks.

[0039] like Figure 1 As shown, the conveyor disc 2 is in the shape of a disc and is rotatably supported on the base 1. It can rotate under the drive of a relevant power source. A plurality of mounting positions are provided on the conveyor disc 2, and the plurality of mounting positions are arranged in the circumferential direction. A fixing seat 21 is installed on the mounting position, and the fixing seat 21 has a structure for clamping objects, which is used to fix the first type of objects and the second type of objects in a fixed posture. The conveyor disc 2 rotates according to a predetermined step distance under the trend of the power source, so as to transport the fixing seat 21 to the said station.

[0040] The transport mechanism 3 includes a transverse moving component 31 and a vertical moving component 31, and the transverse moving component 31 includes a transverse power source, a transverse slide and a transverse slide rail. The transverse slide rail extends in a direction parallel to the projection of the line connecting the work station and the selected position on the horizontal plane, and the transverse slide rail is adapted to the transverse slide rail and slides along its extension direction.

[0041] In an exemplary embodiment, the transport mechanism 3 further comprises a support seat supported on a vertical moving component 31 and at least two clamping arms 33 movably or rotatably connected to the support seat, and the vertical moving component 31 is supported on the transverse moving component 31. At least two clamping arms 33 clamp the first and second categories of objects by moving or rotating. The two clamping arms 33 can move relative to the support seat under the drive of a motor to clamp and release objects. It is understandable that in other embodiments, the support seat can be supported on the transverse moving component 31, and the transverse moving component 31 is supported on the vertical moving component 31.

[0042] The first track 4 is located above the second track 5. The first track 4 has an opening facing upwards for receiving the first type of objects. The first track 4 has a first guide sliding surface inclined from top to bottom. The guide sliding surface is inclined from top to bottom and is used to transport the first type of objects to the target area to enter the next process. The second track 5 has an opening facing upwards for receiving the second type of objects. The second track 5 has a vertical section and an inclined section. The vertical section is located above the inclined section. The opening is arranged above the vertical section. The vertical section has a second guide sliding surface, and the second type of objects are transported to the inclined section through the second guide sliding surface. Through the vertical section, space is left for the first track 4 and the driving mechanism 6 to be arranged. The inclined section has a third guide sliding surface, and the third guide sliding surface is used to transport the second type of objects to the target position so that they can enter the next process. Among them, the angle between the third guide sliding surface and the horizontal plane is smaller than the angle between the second guide sliding surface and the horizontal plane.

[0043] The driving mechanism 6 includes a sliding member and a slide rail, which are slidably matched, the first track 4 is fixedly supported on the sliding member, the slide rail is supported on the base 1, and the slide rail extends in a direction intersecting with the line connecting the station and the position to be selected, so as to reduce the distance of pushing the first track 4 to move. The sliding member is arranged at a position farther away from the station than the object entrance of the second track 5. In this way, the space occupied by the first track 4 and the driving mechanism 6 on the base 1 can be reduced.

[0044] Along the direction of the slide rail, the driving mechanism 6 is configured to drive the first track 4 to move so that the object entrance of the first track 4 is at the selected position or the entrance of the second track 5 is exposed on the moving path of the object transported by the transportation mechanism 3 .

[0045] The object conveying device also includes a control device, which is electrically connected to each power source, including a power source for driving the conveying plate 2 to rotate, a power source for driving the vertical moving part 31 to move, a power source for driving the lateral moving part 31 to move, a power source for driving the driving mechanism 6 to move, and a power source for driving the clamping arm 33 to move. The power source can be a cylinder, a hydraulic cylinder, a screw motor or a drive motor, etc. The control device is used to control the operation of the above power sources.

[0046] The detection mechanism includes one or more of a sensor, an image acquisition device, and an in-position switch. The object conveying device also includes a control device and a power source for driving the transport mechanism 3 and the drive mechanism 6 to move.

The detection mechanism is arranged on the transport mechanism 3, the fixed seat 21, the conveying tray 2, or the base 1 for supporting the conveying tray 2.

[0047] Exemplarily, when the conveyor tray 2 conveys the object on the fixed seat 21 to the workstation, the lateral moving part 31 and the vertical moving part 31 are controlled to work, and the driving arm is controlled to clamp the object on the fixed seat 21 located on the workstation. The control device also determines whether it is a first-class object or a second-class object based on the information of the object detected by the detection mechanism. When it is a first-class object, the lateral moving part 31 and the vertical moving part 31 are controlled to transport the first-class object to the opening of the first track 4, and the clamping arm 33 is controlled to release the first object. When it is a second-class object, the driving mechanism 6 is controlled to push the first track 4 to move, and the lateral moving part 31 and the vertical moving part 31 are controlled to transport the second-class object to the opening of the second track 5, and the clamping arm 33 is controlled to release the first object.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
