[0031] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0032] Please refer to Figures 1 to 4 The utility model provides a retractable fruit suction device, comprising a connecting plate 2, a lifting plate 6, a guide column 3, a spring 4 and a negative pressure suction component 7;
[0033] A plurality of guide posts 3 are provided at the bottom of the connecting plate 2;
[0034] The lifting plate 6 is provided with a guide sleeve 5 corresponding to the guide column 3, and the lifting plate is slidably mounted on the guide column 3 through the guide sleeve 5;
[0035] The spring 4 is sleeved on the guide column 3, one end of the spring 4 is connected to the connecting plate 2, and the other end of the spring 4 is connected to the lifting plate 6;
[0036] The negative pressure suction assembly 7 includes an air suction pipe 71, a suction cup 72 and a fixing plate 73. One end of the air suction pipe 71 is connected to the suction cup 72 and is integrally formed therewith. The connecting plate 2 and the lifting plate 6 are both provided with holes corresponding to the air suction pipe 71. The fixing plate 73 is fixed on the air suction pipe 71 and is fixedly connected to the lifting plate 6.
[0037] The negative pressure air pump generates suction force on the suction cup 72 through the suction pipe 71, and presses the suction cup 72 toward the fruit. When the suction cup 72 is under pressure, the suction cup 72 drives the lifting plate 6 to slide along the axial straight line of the guide column 3, and the spring 4 is deformed, which has a buffering effect on the sucked fruit and can also adapt to the suction of fruits and vegetables of different sizes.
[0038] In this embodiment, a connecting seat 1 is also included, one side of the connecting seat 1 is connected to the connecting plate 2, and the other side of the connecting seat 1 is connected to a robotic arm. The setting of the robotic arm can cooperate with the present application to take out the fruits on the assembly line one by one.
[0039] In this embodiment, a buffer protection sleeve 8 is also included. The buffer protection sleeve 8 is made of nylon or silicone and is sleeved on the suction cup 72 mouth of the suction cup 72. The buffer protection sleeve 8 is used to achieve flexible contact with the fruit to prevent mechanical damage to the fruit.
[0040] In this embodiment, the cross section of the connecting plate 2 is triangular, and three guide posts 3 are provided, which are vertically arranged at three corners of the connecting plate 2, respectively. The triangular connecting plate 2 is stable.
[0041] In this embodiment, the outer wall of the air intake pipe 71 is provided with a plurality of semi-cylindrical bosses at equal intervals along its circumference. The provision of the semi-cylindrical bosses can reduce the contact area between the air intake pipe 71 and the connecting plate 2 and the lifting plate 6, reduce friction, and extend service life.
[0042] It should be noted that the fruits sucked in the present application are cone fruits.
[0043] The working principle of the utility model is as follows:
[0044] The negative pressure air pump generates suction force on the suction cup 72 through the suction pipe 71, and presses the suction cup 72 toward the fruit. When the suction cup 72 is under pressure, the suction cup 72 drives the lifting plate 6 to slide in a straight line along the axial direction of the guide column 3, and the spring 4 is deformed to cushion the sucked fruit. It can also adapt to the suction of fruits and vegetables of different sizes. The buffer protection cover 8 is used to achieve flexible contact with the fruit to prevent mechanical damage to the fruit.
