DETAILED DESCRIPTION

[0029] The technical scheme of the embodiments of the present application will be described clearly and completely in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, and are not all embodiments. The description of the at least one exemplary embodiment is actually only illustrative, and is absolutely not any limitation on the present application and its application or use. Embodiment one:

[0030] As shown in Figure 2 The present embodiment provides a suction cup variable-distance distributing module, which comprises: a variable-distance main cavity 7, a suction cup slide rail mounted in the variable-distance main cavity 7, a plurality of vacuum suction cups 13 linearly arranged and slidingly connected on the suction cup slide rail, and a variable-distance cylinder 4 for pushing the vacuum suction cups 13.

[0031] The side of the suction disc slide rail is provided with a buffer assembly for buffering rigid collision during suction of the vacuum suction disc 13 to the material 12.

[0032] The vacuum suction disc 13 farthest from the variable distance cylinder 4 is fixedly connected to the surface of the suction disc slide rail. Figure 3 、 Figure 5 The adjacent vacuum suction discs 13 are elastically connected by the elastic compression spring 15, and the side wall of the vacuum suction disc 13 is provided with a mounting hole 20, and the elastic compression spring 15 is mounted between the adjacent vacuum suction discs 13 through the mounting hole 20.

[0033] The elastic potential energy of at least two elastic compression springs 15 is different, and the specific selection of the elastic potential energy of the elastic compression spring 15 can be determined according to the actual situation. Preferably, the elastic potential energy of each elastic compression spring 15 is different, and specifically, the elastic potential energy of the elastic compression spring 15 gradually increases from the side of the variable distance cylinder 4.

[0034] The suction disc slide rail includes a first slide rail 11 and a second slide rail 8; the first slide rail 11 and the second slide rail 8 are arranged in parallel with a spacing, and the first slide rail 11 and the second slide rail 8 arranged in parallel with a spacing together form a sliding track for the vacuum suction disc 13 to slide; and a slide rail fixed block 10 is installed at the other end of the suction disc slide rail relative to the end where the variable distance cylinder 4 is located.

[0035] The first slide rail 11 and the second slide rail 8 together form a sliding track to provide a space for the vacuum suction disc 13 to slide, and cooperate with the variable distance cylinder 4. When the variable distance cylinder 4 is extended to push the adjacent vacuum suction disc 13, because the adjacent vacuum suction discs 13 are elastically connected by the elastic compression spring 15, the vacuum suction disc 13 can slide in turn on the sliding track in the pushing direction of the variable distance cylinder 4, the elastic compression spring 15 is compressed, and the vacuum suction disc 13 is arranged side by side. When the variable distance cylinder 4 is retracted and the force disappears, the vacuum suction disc 13 can slide in the opposite direction on the sliding track by the elastic restoring force of the elastic compression spring 15, so that the adjacent vacuum suction discs 13 are elastically separated from each other to form a spacing.

[0036] Figure 2 and Figure 4 ​As shown, the buffer assembly comprises a first spring mounting block 16, a second spring mounting block 14 and a buffer spring 6; the first spring mounting block 16 is fixedly connected to the side wall of the variable-distance main cavity 7, the second spring mounting block 14 is mounted to the side wall of the first sliding rail 11 and the second sliding rail 8; the buffer spring 6 is mounted between the first spring mounting block 16 and the second spring mounting block 14. Further, the sliding rail is provided with a blocking block 9 on the side close to the material to be adsorbed 12; the blocking block 9 can prevent the suction cup sliding rail from separating from the variable-distance main cavity 7, and can also limit the material to be adsorbed 12. Preferably, the blocking block 9 is fixedly connected to the bottom surface of the side wall of the variable-distance main cavity 7 and protrudes inward to the bottom surface of the suction cup sliding rail.

[0037] Since the first spring mounting block 16 is fixedly connected to the side wall of the variable-distance main cavity 7, and the second spring mounting block 14 is mounted to the side wall of the first sliding rail 11 and the second sliding rail 8, the second spring mounting block 14 can move relative to the first spring mounting block 16. When the vacuum suction cup 13 is attached to the surface of the material 12, the extrusion force generated by the vacuum overpressure will make the second spring mounting block 14 move upward to approach the first spring mounting block 16, thereby compressing the buffer spring 6 and forming flexible adsorption.

[0038] The buffer assembly is provided with four and symmetrically arranged on both sides of the sliding rail, so that the extrusion force on the surface of the material 12 during vacuum adsorption can be evenly dispersed.

[0039] As shown in the drawings, Figure 5 As shown, the inside of the vacuum suction cup 13 is provided with an air cavity 17, the side wall of the air cavity 17 is connected with the outside vacuum equipment through an air port 18; the bottom of the vacuum suction cup 13 is provided with an air hole 19, the vacuum suction cup 13 adsorbs the material 12 through the air hole 19, and the air hole 19 is in communication with the air cavity 17. Since the variable-distance air cylinder 4 is retracted, the vacuum suction cups 13 are mutually repelled under the action of the elastic compression spring 15 to form a distance, so that the external detection equipment can conveniently screen out the defective material 12. By using the external vacuum equipment to break the vacuum of the vacuum suction cup 13 adsorbing the defective material 12, the defective material 12 can be separated from the vacuum suction cup 13 and enter the defective product discharge process, without affecting the normal material taking and placing work of the vacuum suction cup 13 adsorbing the good product. Example two:

[0040] As shown in the drawings, Figure 1 As shown in the drawings, based on example one, the material taking and separating mechanism provided by example two comprises the suction cup variable-distance separating module mentioned in example one, and further comprises an up-down air cylinder 1, a rotary servo motor 2, a rotary platform 3 and a mounting plate 5.

[0041] The suction cup variable distance material distribution module is fixedly connected with the rotating platform 3 through the mounting plate 5, the up-down air cylinder 1 is used for pushing the rotating platform 3 in the vertical direction so that the vacuum suction cup 13 of the suction cup variable distance material distribution module sucks the material 12, and the rotating servo motor 2 is fixedly connected on the rotating platform 3 to realize the rotation of the suction cup variable distance material distribution module.

[0042] The working process of the material taking and distributing mechanism in the embodiment is as follows: when taking the material, the up-down air cylinder 1 acts downward, the variable distance air cylinder 4 extends, the force of the variable distance air cylinder 4 acts on the side surface of the adjacent vacuum suction cup 13, and the vacuum suction cup 13 slides on the first sliding rail 11 and the second sliding rail 8 in the action direction in sequence, until the vacuum suction cup 13 is arranged together without gap; then, the vacuum suction cup 13 generates suction force after being sucked by the external vacuum equipment, and when the vacuum suction cup 13 contacts the surface of the material 12, the material 12 is adsorbed by the vacuum suction cup 13; during the adsorption process, the combination of the first sliding rail 11, the sliding rail fixed block 10, the second sliding rail 8, the vacuum suction cup 13 and the second spring mounting block 14 slides upward in the variable distance main cavity 7 under the extrusion force generated by the vacuum overpressure to compress the buffer spring 6, and the reaction force generated by the buffer spring 6 generates pressure on the material 12, so that the flexible suction is realized.

[0043] As shown in Figure 3 After the suction is completed, the up-down air cylinder 1 acts upward, the rotating servo motor 2 controls the rotating platform 3 to rotate to a set angle; the variable distance air cylinder 4 is retracted, the external force disappears, and the reaction force of the elastic compression spring 15 makes each vacuum suction cup 13 slide on the first sliding rail 11 and the second sliding rail 8 in sequence to change the distance, so that the interval between the adsorbed materials 12 is pulled apart.

[0044] The vacuum of any vacuum suction cup 13 is broken through the electric control program control of the external vacuum equipment, and any material 12 can be separated from the material discharge, and other materials 12 are not affected. As a further extension of the embodiment, the materials 12 are displaced to the material taking position, the defective product discharge position and the material discharge position through the displacement module, and the repeated action of the material taking and distributing mechanism in the embodiment can realize the material taking, material discharge and defective product discharge of multiple materials 12 arranged in parallel.

[0045] In the description of the present application, it should be explained that, unless otherwise explicitly specified and limited, the terms “mounting”, “connection”, “connection” should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0046] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and deformations can be made, and these improvements and deformations should also be considered as the protection scope of the present application.
