[0018] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Embodiment 1:

[0019] like Figure 2 As shown, this embodiment provides a suction cup variable distance material dividing module, including: a variable distance main cavity 7, a suction cup slide rail installed in the variable distance main cavity 7, a plurality of vacuum suction cups 13 in a linear array and slidably connected to the suction cup slide rail, and a variable distance cylinder 4 for pushing the vacuum suction cup 13.

[0020] A buffer component is installed on the side of the suction cup slide rail, and the buffer component is used to buffer the rigid collision during the process of the vacuum suction cup 13 adsorbing the material 12.

[0021] Among them, the vacuum suction cup 13 farthest from the variable pitch cylinder 4 is fixedly connected to the surface of the suction cup slide rail. Figure 3 , Figure 5 As shown, adjacent vacuum suction cups 13 are elastically connected via a compression spring 15 , and a mounting hole 20 is provided on the side wall of the vacuum suction cup 13 . The compression spring 15 is installed between adjacent vacuum suction cups 13 through the mounting hole 20 .

[0022] Among the said compression springs 15, at least two compression springs 15 are provided with different elastic potential energies, and the specific selection of the elastic potential energies of the compression springs 15 can be determined according to the actual situation. Preferably, the elastic potential energies of the compression springs 15 are set to be different from each other, and specifically, the elastic potential energies of the compression springs 15 gradually increase from one side of the variable pitch cylinder 4.

[0023] The suction cup 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 each other, and the first slide rail 11 and the second slide rail 8 arranged in parallel with each other together form a sliding track for the vacuum suction cup 13 to slide; a slide rail fixing block 10 is installed at the other end of the suction cup slide rail where the variable pitch cylinder 4 is located.

[0024] The first slide rail 11 and the second slide rail 8 together form a sliding track to provide a space for the vacuum suction cup 13 to slide, and cooperate with the variable pitch cylinder 4. When the variable pitch cylinder 4 extends to push an adjacent vacuum suction cup 13, since the adjacent vacuum suction cups 13 are elastically connected by the compression spring 15, the vacuum suction cups 13 can slide on the sliding track in sequence along the pushing direction of the variable pitch cylinder 4, and the compression spring 15 is compressed until the vacuum suction cups 13 are arranged side by side. When the variable pitch cylinder 4 retracts and the force disappears, the vacuum suction cups 13 can slide in sequence in the opposite direction on the sliding track by the elastic restoring force of the compression spring 15, so that the adjacent vacuum suction cups 13 are bounced apart from each other to form a spacing.

[0025] like Figure 2 and Figure 4 As shown, the buffer assembly includes 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, and the second spring mounting block 14 is installed on the side walls of the first slide rail 11 and the second slide rail 8; the buffer spring 6 is installed between the first spring mounting block 16 and the second spring mounting block 14. Furthermore, a blocking block 9 is provided on one side of the sliding rail close to the material to be adsorbed 12; the blocking block 9 can prevent the suction cup slide rail from detaching from the variable distance main cavity 7 on the one hand, and can limit the material to be adsorbed 12 on the other hand. 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 slide rail.

[0026] Since the first spring mounting block 16 is fixedly connected to the side wall of the pitch-variable main cavity 7, and the second spring mounting block 14 is mounted on the side walls of the first slide rail 11 and the second slide 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 pressed downward against the surface of the material 12, the extrusion force generated by the vacuum overpressure causes the second spring mounting block 14 to move upward close to the first spring mounting block 16, thereby compressing the buffer spring 6, and then forming flexible adsorption.

[0027] The buffer components are provided in four numbers and are symmetrically arranged on both sides of the sliding track, so that the squeezing force on the surface of the material 12 during the vacuum adsorption process can be evenly dispersed.

[0028] like Figure 5 As shown, the vacuum suction cup 13 is provided with an air cavity 17 inside, and the side wall of the air cavity 17 is connected to the external vacuum equipment through the air port 18; the bottom of the vacuum suction cup 13 is provided with an air hole 19, and the vacuum suction cup 13 absorbs the material 12 through the air hole 19, and the air hole 19 is connected to the air cavity 17. When the variable pitch cylinder 4 retracts, the vacuum suction cups 13 are ejected from each other under the action of the compression spring 15 to form a spacing, so that the external detection equipment can easily screen out the defective material 12. The vacuum suction cup 13 that absorbs the defective material 12 is targetedly broken by the external vacuum equipment, so that the defective material 12 can be separated from the vacuum suction cup 13 and enter the defective product discharge process, and it will not affect the normal material picking and placing work of other vacuum suction cups 13 that absorb good products. Embodiment 2:

[0029] like Figure 1 As shown, based on the first embodiment, the second embodiment provides a material picking and dividing mechanism. In addition to the suction cup variable distance dividing module mentioned in the first embodiment, the material picking and dividing mechanism also includes: upper and lower cylinders 1, a rotary servo motor 2, a rotating platform 3 and a mounting plate 5.

[0030] The suction cup variable distance material dividing module is fixedly connected to the rotating platform 3 via a mounting plate 5, the upper and lower cylinders 1 are used to push the rotating platform 3 in the vertical direction so that the vacuum suction cup 13 of the suction cup variable distance material dividing module absorbs the material 12, and the rotary servo motor 2 is fixedly connected to the rotating platform 3 to realize the rotation of the suction cup variable distance material dividing module.

[0031] The working process of the material taking and dividing mechanism of this embodiment is as follows: when taking materials, the upper and lower cylinders 1 move downward, and the variable pitch cylinder 4 extends out. The force of the variable pitch cylinder 4 acts on the sides of the adjacent vacuum suction cups 13, so that a plurality of vacuum suction cups 13 slide in turn on the first slide rail 11 and the second slide rail 8 along the direction of action until the vacuum suction cups 13 are arranged side by side without gaps; subsequently, the vacuum suction cups 13 generate suction after being vacuumed by connecting to an external vacuum device, and when the surface of the material 12 is over-pressured when in contact with the material 12, the material 12 is adsorbed by the vacuum suction cups 13; during the adsorption process, the combination of the first slide rail 11, the slide rail fixing block 10, the second slide rail 8, the vacuum suction cups 13 and the second spring mounting block 14 slides upward in the variable pitch main cavity 7 under the extrusion force generated by the vacuum overpressure, thereby compressing the buffer spring 6, and the reaction force generated by the buffer spring 6 generates pressure on the material 12, thereby realizing flexible absorption.

[0032] like Figure 3 As shown, after the suction is completed, the upper and lower cylinders 1 move upward, and the rotary servo motor 2 controls the rotating platform 3 to rotate to the set angle; the variable pitch cylinder 4 retracts, the external force disappears, and the reaction force of the compression spring 15 causes each vacuum suction cup 13 to slide and change pitch on the first slide rail 11 and the second slide rail 8 in turn, thereby increasing the distance between the adsorbed materials 12.

[0033] By controlling any vacuum cup 13 to break vacuum through the electronic control program of the external vacuum device, any material 12 can be released without being affected by other materials 12. As a further extension of this embodiment, the material 12 is shifted to the material taking position, the defective product discharge position, and the material discharge position through the shift module, and combined with the repeated action of the material taking and material dispensing mechanism of this embodiment, the material taking, discharge, and defective product discharge of multiple parallel materials 12 can be realized.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
