[0035] Referring to Figure 1 , the fruit processing device 100 in an embodiment of the present application is shown, taking a fruit slicing device as an example, which includes a frame 10, a clamping and transferring mechanism, a slicing mechanism 60, a slicing platform 70, and a feeding mechanism 80. The slicing platform 70 is provided with a material taking station and a slicing station; the slicing mechanism 60 is installed on the frame 10 and is arranged above the slicing station of the slicing platform 70; the feeding mechanism 80 is installed in the frame 10 and is used to transport the fruit to be processed to the material taking station of the slicing platform 70; the clamping and transferring mechanism is installed in the frame 10 and is located above the slicing platform 70, and is used to clamp and pick up the fruit to be processed transported by the feeding mechanism to the material taking station and then transfer it to the slicing station.
[0036] In the illustrated embodiment, the fruit processing device 100 defines X-axis direction (first direction), Y-axis direction (second direction), and Z-axis direction (third direction) perpendicular to each other, the material taking station and the slicing station of the slicing platform 70 are arranged at two ends of the Y-axis direction, and the slicing mechanism 60 is arranged above the slicing station along the Z-axis direction. As shown in the figure, the first direction and the second direction are horizontal directions, and the third direction is a vertical direction.
[0037] Referring to Figure 2, the clamping and transferring mechanism comprises a fruit clamp 20, a transferring rotation module 30, a transferring horizontal movement module 40 and a transferring reciprocating module 50. The fruit clamp 20 is used for picking and clamping fruits; the fruit clamp 20 is installed at the rotating end of the transferring rotation module 30, and the transferring rotation module 30 can drive the fruit clamp 20 to rotate; the transferring rotation module 30 is connected with the driving end of the transferring horizontal movement module 40, and the transferring horizontal movement module 40 can drive the transferring rotation module 30 and the fruit clamp 20 installed at the rotating end of the transferring rotation module 30 to move horizontally along the X-axis direction; the transferring reciprocating module 50 drives the fruit clamp 20 to reciprocate along the Y-axis direction between the material taking station and the slicing station, so as to clamp the fruits at the material taking station to the slicing station for slicing. In this way, through the cooperation of the transferring rotation module 30, the transferring horizontal movement module 40 and the transferring reciprocating module 50, the fruit clamp 20 can be moved to the required position and rotated to the required angle, so as to accurately align the blade of the slicing mechanism 60 with the expected optimal cutting line of the fruit to be processed, and provide ideal position conditions for the blade to slice the fruit.
[0038] Specifically, the transferring rotation module 30 is driven by a motor, which comprises a rotating motor 31, a speed reducer 32 and a bearing seat 33 connected in sequence along the Z-axis direction. The power output by the rotating motor 31 is transmitted to the fruit clamp 20 after being decelerated by the speed reducer 32, so as to drive the fruit clamp 20 to rotate. At the same time, the transferring rotation module 30 is fixedly connected to the driving end of the transferring horizontal movement module 40 through the bearing seat 33, so as to ensure the stability of the work.
[0039] The specific structure of the transferring horizontal movement module 40 is not particularly limited, and can adopt a ball screw drive, or a linear drive mode such as an electric sliding table, an air cylinder or a hydraulic cylinder. Figure 2 In the embodiment shown in the figure, the transferring horizontal movement module 40 adopts a linear motor to perform linear motion along the X-axis direction.
[0040] The specific structure of the transferring reciprocating module 50 is not particularly limited, and can adopt a ball screw drive, or a linear drive mode such as a linear motor, an electric sliding table, an air cylinder or a hydraulic cylinder. Figure 2 In the embodiment shown in the figure, the transferring reciprocating module 50 adopts a belt pulley as a transmission mechanism, and the transferring horizontal movement module 40 is installed on the belt of the belt pulley, so as to drive the fruit clamp 20 to perform reciprocating linear motion along the Y-axis direction.
[0041] Please refer to Figure 3 The fruit clamp 20 comprises a clamping driving member 21 and two oppositely arranged clamping arms 22. The two clamping arms 22 are installed on the clamping driving member 21, and the clamping driving member 21 can drive the two clamping arms 22 to move towards or away from each other along the X-axis direction, so as to open and close the clamping arms 22.
[0042] In the illustrated embodiment, the clamping drive 21 is in the form of an electrically operated clamping jaw which is arranged to clamp the fruit by driving the two clamping arms 22 to move relative to one another. In other embodiments, the clamping drive 21 can also be in the form of a clamping cylinder or the like, without being limited thereto.
[0043] Please refer to Figure 4 and Figure 5 The clamping arm 22 has one end connected to the moving end of the clamping drive 21 and the other end away from the clamping drive 21, which is the clamping end for clamping the fruit to be processed. The clamping end of the clamping arm 22 is provided with a clamping portion 221 and a clamping piece 222, and the clamping piece 222 is rotatably installed above the clamping portion 221 through a hinge shaft 223 arranged along the Y-axis direction.
[0044] More specifically, the clamping portion 221 is formed with a first profiling surface 2211 facing upward, and the clamping piece 222 installed above the clamping portion 221 is formed with a second profiling surface 2221 facing downward, and the second profiling surface 2221 is below the hinge shaft 223. That is, on the same clamping arm 22, the first profiling surface 2211 of the clamping portion 221 is opposite to the second profiling surface 2221 of the clamping piece 222. The first profiling surface 2211 and the second profiling surface 2221 are in the shape of a concave curved surface, and respectively imitate the surface shape of the lower part and the upper part of one side of the fruit to be processed. The first profiling surface 2211 and the second profiling surface 2221 of one side of the clamping arm 22 are respectively arranged opposite to the first profiling surface 2211 and the second profiling surface 2221 of the other side of the clamping arm 22 along the X-axis direction, so that through the relative movement of the two clamping arms 22 along the X-axis direction, the fruit to be processed can be clamped between the clamping ends of the two clamping arms 22, and the first profiling surface 2211 and the second profiling surface 2221 of the two clamping arms 22 respectively contact the lower surface and the upper surface of the fruit to be processed.
[0045] In order to better hold the fruit to be processed to form a stable clamping, two clamping parts 221 and two clamping pieces 222 are respectively arranged on the clamping end of each clamping arm 22 along the Y-axis direction, the first profiling surfaces 2211 of the two clamping parts 221 arranged along the Y-axis direction are oppositely arranged, and the second profiling surfaces 2221 of the two clamping pieces 222 arranged along the Y-axis direction are also oppositely arranged. That is, two clamping parts 221 and two clamping pieces 222 are arranged on the clamping end of the single clamping arm 22, four clamping parts 221 and four clamping pieces 222 are arranged on the two clamping arms 22, and the four clamping parts 221 and the four clamping pieces 222 form a profiling groove for clamping the fruit to be processed; the four clamping parts 221 provide clamping force to the fruit to be processed from the left front, left rear, right front and right rear respectively, and the four clamping pieces 222 provide clamping force to the fruit to be processed from the left front, left rear, right front and right rear respectively. Since each clamping piece 222 can rotate independently around the respective hinge shaft 223, the second profiling surfaces 2221 on the four clamping pieces 222 completely fit the surface of the fruit from different directions and form self-locking, thereby forming a very stable clamping of the fruit.
[0046] When the clamping driving member 21 drives the two clamping arms 22 to approach each other along the X-axis direction to clamp the fruit to be processed, the fruit contacts the first profiling surfaces 2211 of the clamping parts 221 and the second profiling surfaces 2221 of the clamping pieces 222, and the clamped fruit generates a pressing force F (as shown in Figure 4 The clamping piece 222 can rotate around the hinge shaft 223, so that its second profiling surface 2221 maximally contacts the fruit, thereby more stably clamping the fruit; at the same time, since the hinge shaft 223 is located above the second profiling surface 2221, the pressing force F of the fruit forms a torque on the clamping piece 222 to rotate towards the clamping end, so that the fruit cannot be turned out of the profiling groove formed by the first profiling surface 2211 and the second profiling surface 2221, thus forming self-locking, and the fruit will not slide relative to the clamping arm 22, thereby creating good conditions for the transfer and slicing of the fruit.
[0047] Before the slicing mechanism 60 cuts the fruit to be processed clamped by the fruit clamp 20, the fruit clamped by the clamping arm 22 on the clamping driving member 21 can be moved to the desired position and rotated to the desired angle by the cooperation of the transfer reciprocating module 50, the transfer horizontal moving module 40 and the transfer rotating module 30, so as to accurately align the blade in the slicing mechanism 60 with the expected best cutting line of the fruit to be processed, thereby providing position conditions for the cutting of the fruit by the blade.
[0048] After the slicing mechanism 60 completes the slicing of the fruit to be processed clamped by the clamping arm 22, the clamping driving member 21 drives the two clamping arms 22 to move away from each other along the X-axis direction to release the fruit piece after slicing.
[0049] Please refer to Figures 1 to 5 When the fruit processing device 100 is working, the feeding mechanism 80 is started to deliver the fruit to be processed to the taking station on the slicing platform 70. The transfer reciprocating module 50 moves the fruit clamp 20 along the Y-axis direction to the taking station, at the same time, the transfer horizontal moving module 40 and the transfer rotating module 30 adjust the fruit clamp 20 to the position and angle suitable for clamping the fruit on the taking station, the clamping driving part 21 of the fruit clamp 20 drives the left and right clamping arms 22 to move towards each other along the X-axis direction to clamp the fruit on the taking station. The transfer reciprocating module 50 moves the fruit clamp 20 along the Y-axis direction to the slicing station, at the same time, the transfer horizontal moving module 40 and the transfer rotating module 30 adjust the fruit clamp 20 to the optimal slicing position and angle below the slicing mechanism 60. The slicing mechanism 60 is started to cut the fruit clamped by the fruit clamp 20. In this way, the slicing processing of the fruit is completed.
[0050] The fruit processing device 100 can also be provided with a vision module (not shown in the figure), which is located on one side of the clamping and transfer mechanism. The vision module takes pictures of the fruit to be processed before slicing. According to the fruit image obtained by the vision module, the shape and size of the fruit can be determined, and then the position of the corresponding optimal cutting line can be determined according to the shape and size of the fruit.
[0051] In summary, compared with the prior art, the fruit clamp and the fruit processing device of the present application have at least the following advantages: In the fruit clamp of the embodiment of the present application, two relatively movable clamping arms are used to pick up and clamp the fruit to be processed. A clamping part with a second profiling surface is rotatably installed on the clamping end of each clamping arm. The clamping part and the clamping part with a first profiling surface together clamp the fruit to be processed. The first profiling surface of the clamping part and the second profiling surface of the clamping part have a curved surface shape similar to that of the fruit, so the contact between them is a large-area surface contact, which can significantly reduce the probability of damage to the fruit skin. Since the clamping part can rotate relatively, the contact between it and the fruit to be processed is a flexible contact, which can buffer the force acting on the fruit to be processed in the instant of contact, avoiding damage to the fruit skin caused by hard contact. On the other hand, the squeezing force of the fruit forms a torque on the clamping part that rotates the clamping end, so the fruit cannot turn over from the profiling groove formed by the first profiling surface and the second profiling surface. In this way, self-locking is formed to ensure that the fruit will not slide relative to the clamping arm, creating good conditions for the transfer and processing of the fruit.
[0052] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which shall be covered within the protection scope of the present application. The protection scope of the present application shall be subject to the protection scope of the claims.
