[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1: See Figure 1-4 As shown, a nozzle mounting structure includes a nozzle connecting mechanism and a nozzle 1 detachably mounted on the nozzle connecting mechanism; the nozzle connecting mechanism includes a connecting block 2 and a nozzle mounting member 3, and a cylinder connecting hole 4 is provided on the top of the connecting block 2;

[0030] The bottom of the connecting block 2 is provided with a mounting groove 5 penetrating at both ends, the top of the nozzle mounting member 3 is mounted in the mounting groove 5, and the nozzle mounting member 3 is limited in the mounting groove 5 by a locking bolt 6;

[0031] A main air duct 7 penetrating the left and right ends is provided in the middle of the suction nozzle mounting member 3, and a plurality of branch air ducts 8 connected to the main air duct 2 are installed at intervals from left to right at the bottom of the suction nozzle mounting member 3. The top of the suction nozzle 1 is connected to the bottom of the connecting block 2, and the top of the suction nozzle 1 is connected to the bottom of the branch air duct 8.

[0032] The two ends of the main airway are air pipe joint installation positions, and the two ends of the main airway are used for connecting the air pipe through the corresponding air pipe joint installation positions. When replacing products of different sizes, if you need to replace nozzles of different sizes and numbers, directly remove the air pipe from the nozzle installation part, and then directly remove the nozzle installation part and the installation groove of the connecting block, and then replace the nozzle installation part with the corresponding number of nozzles of corresponding size and directly install it into the installation groove, and limit the nozzle installation part directly in the installation groove by the locking bolt, and finally quickly install the air pipe and the air pipe joints at both ends of the air pipe and the main airway. In this way, the replacement efficiency is high and the difficulty of replacement is reduced.

[0033] At the same time, even if the branch airway structure at the bottom is different, it can be quickly replaced as long as the top of the nozzle mounting piece can cooperate with the mounting groove, and it is more adaptable.

[0034] At the same time, the air pipes at both ends of the main airway can generate positive pressure on one side and negative pressure on the other side without interfering with each other, or solenoid valves are respectively provided on the air pipes on both sides. Under normal circumstances, only one side of the air pipe is enabled and the other side is not used. When the air supply and negative pressure equipment connected to one side of the air pipe is damaged, the air supply and negative pressure equipment connected to the air pipe on the other side is directly used.

[0035] See also Figure 2 , 4 As shown, an interface is provided at the bottom of each branch airway 8, and the suction nozzle is detachably connected to the interface. If the suction nozzle is damaged, the suction nozzle and the branch airway can be quickly replaced through the interface.

[0036] See also Figure 1 , 3 As shown, the front and rear sides of the connecting block 2 are respectively provided with mounting holes 9 penetrating the mounting groove 5, and the two sides of the nozzle mounting member 3 are respectively provided with screw holes 10 facing the mounting holes 9, and each of the mounting holes 9 is inserted with a locking bolt 6, and the inner end of the locking bolt 6 is threadedly connected to the corresponding screw hole 10.

[0037] In this embodiment, the installation holes and the screw holes are arranged so that the connection block and the nozzle installation part can be quickly installed by passing the locking bolt through the installation hole of the connection block and screwing it into the screw hole on the nozzle installation part. When the nozzle installation part is disassembled, the locking bolt only needs to be taken out of the screw hole to achieve the quick disassembly of the nozzle installation part.

[0038] More preferably, the mounting groove can be a T-shaped groove, and the top of the suction nozzle mounting piece is a T-shaped structure that matches the mounting groove. In this way, when the locking bolt is not installed, preliminary positioning can be performed, and the suction nozzle mounting piece and the connecting block can be manually locked with the locking bolt later.

[0039] See also Figure 2 , 4 As shown, the bottom of the cylinder connecting hole 4 is connected to the mounting groove 5 , and a coaxially arranged clearance hole 11 is provided at the bottom of the cylinder connecting hole 4 , and the diameter of the clearance hole 11 is larger than the diameter of the cylinder connecting hole 4 .

[0040] The cylinder connecting hole and the giving way hole are set, and the connecting block can be used to connect with the cylinder through the cylinder connecting hole and the giving way hole. The cylinder drives the connecting block, the suction nozzle mounting part and the suction nozzle to move up and down to realize the grabbing and discharging of materials.

[0041] See also Figure 4 As shown, the utility model also provides an auxiliary material grabbing device, including a bracket 12 and a cylinder 13 installed on the bracket 12, and also includes the above-mentioned nozzle installation structure, and the output shaft at the bottom of the cylinder is connected to the connecting block through a connecting piece;

[0042] The output shaft at the bottom of the cylinder 13 is connected to the cylinder connecting hole 4 of the connecting block 2 via a connecting piece.

[0043] The bracket is used to connect with the driving mechanism. The driving mechanism can be a device that drives the bracket to move in the X, Y, and Z axis space, such as a three-axis manipulator or a five-axis manipulator, which can realize that the bracket can be moved to a predetermined position to suck and discharge materials. The output shaft of the cylinder is connected through a connector and a connecting block. In this way, the output shaft of the cylinder is not directly connected to the connecting block. When the cylinder and the connecting block need to be separated, the output shaft of the cylinder can be not directly connected to the connecting block, which is convenient for installation, disassembly and replacement.

[0044] See also Figure 4 As shown, the connecting member includes a connecting plate 14 and a connecting bolt 15, the top of the connecting bolt 15 passes through the cylinder connecting hole 4 and is connected to the bottom of the connecting plate 14, and the output shaft of the cylinder 13 is connected to the connecting plate 14. The screw head of the connecting bolt is in the screw hole mounting hole, so that the bottom of the connecting bolt will not leak out of the mounting groove, and will not affect the installation and removal of the nozzle mounting member.

[0045] More preferably, there are two cylinder connection holes and two connecting bolts, so as to ensure that after the connecting block and the connecting plate are connected, the connecting block will not rotate relative to the connecting plate.

[0046] Furthermore, a guide ring 16 is provided on the side wall of the cylinder 13 , and a guide rod 17 is provided on the top of the connecting plate 14 , and the upper part of the guide rod 17 is slidably connected to the guide ring 16 .

[0047] In this embodiment, in order to ensure that the suction nozzle can move stably along the axial direction of the cylinder output shaft during the extension and retraction of the cylinder output shaft, the guide ring and the guide rod are arranged to ensure that the suction nozzle can move stably along the axial direction of the cylinder output shaft.

[0048] See also Figure 4 As shown, the guide rod 17 is also threaded with an adjusting limit nut 18, and the adjusting limit nut 18 is arranged above the guide ring 16;

[0049] When the cylinder output shaft is extended, the bottom of the adjusting limit nut abuts against the top surface of the guide ring.

[0050] A rubber buffer layer 19 is provided on the top of the guide ring 16; when the cylinder output shaft is in an extended state, the bottom of the regulating limit nut abuts against the rubber buffer layer.

[0051] By adjusting the setting of the limit nut and the rubber buffer layer, after changing different suction nozzles, the stroke may also change, and the stroke adjustment of the cylinder is not very precise, or the stability is not particularly good. Therefore, by adjusting the setting of the limit nut and rotating the position of the limit nut on the guide rod, the stroke of the cylinder output shaft can be adjusted, so that the stroke of the cylinder is mechanically limited by the limit nut and the guide ring to ensure that the stroke is accurately limited. The setting of the rubber buffer layer, after the cylinder output shaft is extended, when the limit nut and the guide ring are in contact, it is a flexible contact, no rigid collision will occur, low noise, low vibration, can extend the service life.
