In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in FIG. 1, the present embodiment provides a clamping and rotating device for nondestructive testing of fruits and vegetables, which is used for clamping and rotating fruits, and keeps the clamping force moderate during clamping and rotating processes, thereby avoiding fruit damage.
This centre gripping rotary device is including relative left connecting plate 1 and the right connecting plate 17 that sets up, and the lower relative position along of left connecting plate 1 and right connecting plate 17 all is equipped with the mounting hole, and brace table 2 passes through the mounting hole to be fixed on left connecting plate 1 and right connecting plate 17, and left lead screw 3 and right lead screw 16 are installed to the relative position about brace table 2. The relative movement of the clamping mechanism can be driven by the opposite movement of the left screw rod 3 and the opposite movement of the right screw rod 16.
The left positioning sleeve 4 is provided with a pressure sensor 6, a left fruit support bearing sleeve 7 and a left fruit support bearing 8, and the left fruit support 9 can freely rotate around the axis of the left fruit support. The existence of the left fruit bearing sleeve 7 and the left fruit bearing 8 can ensure that the left fruit bearing 9 can not damage the pressure sensor 6 in the rotating process. A spring 30 is arranged in the left fruit bearing sleeve 7, and when no pressing force is applied, the left fruit bearing sleeve 7 and the left fruit bearing 9 are separated under the action of the spring 30; when the pressing force is applied, the spring 30 is gradually compressed, so that the phenomenon that the pressure sensor 6 is subjected to large instant impact to cause inaccurate reading is avoided, and the phenomenon that the fruit is damaged due to instant impact is also avoided. And a limiting device is arranged on the left positioning sleeve 4, so that the left fruit bearing sleeve 7 and the left fruit bearing 8 can not fall off under the reaction force of the spring 30 under the condition of removing the pressure.
And a rotary stepping motor 14 is arranged on the right positioning sleeve 15 and used for rotating after clamping fruits to detect the internal quality of the fruits in an all-round manner. The rotary stepping motor 14 is connected with the right fruit support 12, and the axes of the right fruit support 12 and the left fruit support 9 are collinear, so that smooth rotation is ensured.
The vision camera 11 is arranged behind the installation position of the support table 2, and can be used for detecting whether fruits and vegetables reach the middle part of a fruit tray which is a detection position or not on one hand through the vision camera 11, when no fruit reaches the detection position, the system is in a silent state, and when the fruit reaches the detection position, the vision camera 11 sends an instruction to the central controller to start the operation of the whole system; on the other hand, the vision camera 11 is used for collecting and detecting the whole surface of the fruits and vegetables in an all-around manner, feeding back detection data to the central processing unit, and completing the core action of the equipment.
The front arc door plate 24 and the rear arc door plate 10 are opened and closed simultaneously under the driving of a front gear stepping motor 21 and a rear gear stepping motor which are fixed on a front fixing support plate 20 and a rear fixing support plate 29. The front arc-shaped door plate 24 and the rear arc-shaped door plate 10 are used for receiving fruits and vegetables to be detected in a closed state, the arc-shaped design of the front arc-shaped door plate and the rear arc-shaped door plate is used for correcting the falling state of the fruits and vegetables, so that the fruits and vegetables are adaptive to the clamping position, and the longest diameter of the fruits and vegetables is coaxial with the right fruit support 12 and the left fruit support 9 as far as possible, so that the fruits and vegetables can.
The pressure sensor 6 is connected with a controller which is respectively connected with the left screw rod 3, the rotary stepping motor 14, the right screw rod 16, the front gear stepping motor 21 and the rear gear stepping motor 25. The clamping force required for different types of fruit may vary. When the vision camera 11 detects that the detected fruits and vegetables reach a detection position (a bearing position formed by closing the front arc-shaped door plate 24 and the rear arc-shaped door plate 10), the left screw rod 3 and the right screw rod 16 are started to rotate back to back for clamping, when a pressure value sensed by the pressure sensor 6 reaches a set value, the controller sends a control signal, the left screw rod 3 and the right screw rod 16 stop rotating, the left screw rod 3 and the right screw rod 16 keep stable under the self-locking property of the left screw rod 3 and the right screw rod 16, the front gear stepping motor 21 and the rear gear stepping motor 25 rotate to drive the front arc-shaped door plate 24 and the rear arc-shaped door plate 10 to be opened, the door plate is prevented from damaging the surfaces of the fruits and vegetables in the rotating process, and then the rotating stepping motor 14 rotates for 380 degrees to prevent the sliding, the step dropping and other errors from.
In this embodiment, the arc-shaped door panel driving mechanism includes a gear stepping motor and a gear rack mechanism, the gear motor is connected with a rack, and the rack is connected through a hinge on the arc-shaped door panel to realize a supporting function, and a person skilled in the art can also select other arc-shaped door panel rotating mechanisms, such as a driving motor and a screw rod mechanism, as long as the rotation of the front arc-shaped door panel 24 and the rear arc-shaped door panel 10 can be realized; in this embodiment, the left fruit tray 9 and the right fruit tray 12 are both cone-shaped structures, and the large diameter ends (i.e. the pedicles and calyces of the fruits) of the left fruit tray 9 and the right fruit tray 12 are oppositely arranged to be self-adapted to the cones at the two ends of the fruits, so that the long diameter and the left and right fruit trays are ensured to be coaxial in the pushing and clamping process, the contact area with the fruits is enlarged, the local pressure is reduced, and the fruits are better clamped and supported.
It should be noted that, in this embodiment, the front arc door panel 24 and the rear arc door panel 10 drive the racks to be synchronously driven by two motors, so as to implement the actions of the front arc door panel 24 and the rear arc door panel 10. One skilled in the art can remove two separate control devices and replace the two separate control devices with a three-bar linkage mechanism, and the linkage of the two arc-shaped door panels can be realized by one connecting bar controlled by a single motor, and the actions of the front arc-shaped door panel 24 and the rear arc-shaped door panel 10 can be realized by only one supporting plate driving mechanism.
The bearing plate 19 and the small hinge 18 are matched with the height adjusting bolt 23 for use so as to adapt to different fruit and vegetable transportation devices, the fruits and vegetables can smoothly fall into the arc door plate combined groove from the transportation equipment, and the shape of the bearing plate can be changed by the technical personnel in the field aiming at different transportation lines, such as a V-shaped plate and the like.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present specification should not be construed as a limitation of the present invention.
