DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 5 The utility model discloses a multi-station automatic feeding machine, comprising: a bracket 1, a turntable 2 is rotatably connected to the bracket 1, a plurality of vertical guide frames 4 are circumferentially evenly spaced on the turntable 2, the turntable 2 is transmission-connected with a rotation driving part, a pneumatic lifting part is arranged in the vertical guide frame 4, any pneumatic lifting part is connected to a charging and discharging control part, and the charging and discharging control part is fixedly connected to the bracket 1.

[0027] When in use, different materials are placed in each vertical guide frame 4 respectively, and the turntable 2 can be driven to rotate by the rotating drive part, and the rotation of the turntable 2 drives each vertical guide frame 4 to rotate, thereby realizing the switching of materials. When the required material is rotated to the bottom of the robot arm, the corresponding pneumatic jacking part is driven by the inflation and deflation control part to make the material rise, which is convenient for the robot arm to pick up. After the material is picked up, the turntable 2 is driven by the rotating drive part to rotate and switch the vertical guide frame 4 corresponding to the robot arm to realize the switching of materials. The setting of multiple vertical guide frames 4 realizes the switching of multiple stations, which is convenient for switching and loading of different materials, avoids frequent loading by dedicated personnel, and improves production efficiency.

[0028] A further optimized solution is provided, in which the pneumatic lifting part comprises an airbag 9, which is arranged in the vertical guide frame 4, a support plate 8 is fixedly connected to the top of the airbag 9, the support plate 8 is vertically slidably connected to the corresponding vertical guide frame 4, the bottom of the airbag 9 is connected to the top of a connecting hole 10, the connecting hole 10 is provided in the turntable 2, a self-closing connecting air nozzle 7 is coaxially fixed to the bottom end of the connecting hole 10, the connecting hole 10 is connected to the self-closing connecting air nozzle 7, and any self-closing connecting air nozzle 7 is connected to the inflation and deflation control part.

[0029] When the turntable 2 rotates to move the airbag 9 in any vertical guide frame 4 to the top of the inflation and deflation control part, the inflation and deflation control part inflates the airbag 9 through the self-closing connecting air nozzle 7 and the connecting hole 10 of the airbag 9, lifts up the corresponding support plate 8, and realizes the rising of the material at this workstation. After the material has risen, the airbag 9 is no longer connected to the inflation and deflation control part. At this time, the airbag 9 will not leak under the action of the self-closing connecting air nozzle 7, and the material at this workstation is maintained at a corresponding height.

[0030] Further optimized solution, the self-closing communicating air nozzle 7 includes an air nozzle wall 11, the air nozzle wall 11 is coaxially fixed to the bottom of the corresponding communicating hole 10, a coaxially arranged annular vertical slide groove 12 is provided in the air nozzle wall 11, a sliding ring 14 is vertically slidably connected in the annular vertical slide groove 12, the sliding ring 14 is magnetically connected to the inflation and deflation control part, and the middle part of the sliding ring 14 is connected to the inflation and deflation control part;

[0031] An elastic member is provided between the top of the sliding ring 14 and the inner wall of the top of the annular vertical slide groove 12;

[0032] A sealing portion is sealingly matched at the through hole in the middle of the sliding ring 14 , and the sealing portion is coaxially fixed in the air nozzle wall 11 .

[0033] Further optimized solution, the blocking part includes an air blocking column 16, the diameter of the air blocking column 16 matches the middle through hole of the sliding ring 14, the air blocking column 16 and the middle through hole of the sliding ring 14 are vertically slidably arranged, and the bottom end of the air blocking column 16 is coaxially fixed with a sealing ring 17 for preventing air leakage;

[0034] One ends of a plurality of connecting columns 15 are fixedly connected to the top of the air blocking column 16 at equal intervals in the circumferential direction, and the other ends of the connecting columns 15 are fixedly connected to the inner wall of the air nozzle wall 11 .

[0035] According to a further optimization scheme, the elastic member is a spring 13 , the top end of the spring 13 is fixedly connected to the top inner wall of the annular vertical slide groove 12 , the bottom end of the spring 13 is fixedly connected to the top of the sliding ring 14 , and the spring 13 is coaxially arranged in the annular vertical slide groove 12 .

[0036] To further optimize the solution, the inflation and deflation control part includes a docking air nozzle 19, the bottom of the docking air nozzle 19 is coaxially fixed with the air outlet end of the air pump 5, the air outlet end of the air pump 5 is connected to the docking air nozzle 19, the top of the docking air nozzle 19 is coaxially fixed with a magnetic ring 18, the magnetic ring 18 is magnetically connected to the sliding ring 14, the docking air nozzle 19 is connected to the middle part of the sliding ring 14, and the air pump 5 is fixed to the bracket 1.

[0037] In the initial state, the self-closing connecting air nozzle 7 is in a closed state. At this time, the spring 13 is at its initial length, and the air blocking column 16 is inserted into the through hole in the middle of the sliding ring 14. Under the action of the sealing ring 17, the gas cannot leak out or enter through the through hole in the middle of the sliding ring 14, thereby maintaining the corresponding amount of gas in the airbag 9 and ensuring the expansion degree of the airbag 9.

[0038] When the docking air nozzle 19 of the air pump 5 is docked with any self-closing connecting air nozzle 7, the magnetic ring 18 attracts the sliding ring 14 under the action of magnetic attraction, so that the sliding ring 14 slides down in the annular vertical slide groove 12, so that the spring 13 is stretched. At this time, since the position of the air blocking column 16 does not change, the sliding ring 14 moves downward, so that the middle hole of the sliding ring 14 is separated from the air blocking column 16, and the gas can enter or flow out through the middle hole of the sliding ring 14. At this time, the degree of lifting of the material in the vertical guide frame 4 can be adjusted by inflating or deflating the corresponding air bag 9 through the air pump 5.

[0039] When the docking air nozzle 19 of the air pump 5 is separated from any self-closing connecting air nozzle 7, the sliding ring 14 is no longer affected by the magnetic attraction. Under the action of the spring 13 restoring its initial length, the air blocking column 16 is inserted into the middle through hole of the sliding ring 14 again to prevent air leakage.

[0040] According to a further optimized solution, the rotation driving part includes a gear 6 rotatably connected to the bracket 1 , the gear 6 is meshed with the turntable 2 , the gear 6 is connected to the output shaft of the motor 3 , and the fixed end of the motor 3 is fixedly connected to the bracket 1 .

[0041] The motor 3 drives the gear 6 to rotate, and the turntable 2 rotates under the meshing action, thereby realizing the switching of the workstations.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
