[0033] In order to make those skilled in the art better understand the technical scheme of the utility model, the utility model will be further introduced in detail in conjunction with the drawings below.

[0034] Please refer to Figures 1-4 A kind of suction gripper mechanism for stamping part, comprising:

[0035] Rod handle 1, it is the pipe structure of ventilation, to be able to connect the air source equipment outside to carry out the suction operation to stamping part;

[0036] Main pipeline 2, it is vertically connected to one end of rod handle 1 and is connected with rod handle 1, and main pipeline 2 changes airway direction, to facilitate hand-held rod handle 1 to stretch out and suck the stamping part below;

[0037] First branch pipe 3, it is vertically connected to the end of main pipeline 2 opposite to rod handle 1 and is connected with main pipeline 2;

[0038] Main suction disc 4, it is set on the end of first branch pipe 3 opposite to main pipeline 2 and is connected with first branch pipe 3;

[0039] Through air source generation air negative pressure, through rod handle 1, main pipeline 2, first branch pipe 3, to main suction disc 4, make main suction disc 4 align workpiece, to be able to adsorb on workpiece surface, realize the suction operation of stamping part.

[0040] Second branch pipe 5, which is a plurality of the same structure and evenly distributed circumferentially at the end of the main pipe 2 opposite the rod-shaped handle 1, the second branch pipe 5 is connected with the main pipe 2; and

[0041] Sub-suction cup 6, which is provided on the second branch pipe 5 opposite the end of the main pipe 2 and connected with the second branch pipe 5.

[0042] By generating air negative pressure through the air source, through the rod-shaped handle 1, the main pipe 2, the first branch pipe 3, and then to the sub-suction cup 6, the sub-suction cup 6 is aligned with the workpiece to be able to be adsorbed on the surface of the workpiece, realizing the suction operation of the stamping part. In addition, the main suction cup 4 cooperates with multiple sub-suction cups 6 to be able to be adsorbed on different point positions on the surface of the stamping part, so as to cope with stamping parts of different sizes and different shapes, even if the stamping part has a local uneven position, it can also be adsorbed on the surface of the workpiece through the main suction cup 4 or the sub-suction cup 6 of other point positions, realizing the suction operation of the stamping part.

[0043] Further, the rod-shaped handle 1 is connected to the external vacuum pump through the pipeline to provide the air source. Specifically, the control operations such as the switch of the vacuum pump, the suction and blowing of air are all common knowledge known to those skilled in the art, and will not be repeated here. Among them, the switch for controlling the suction and blowing operation of the vacuum pump can be provided on the rod-shaped handle 1 to suck the stamping part when sucking air and remove the stamping part when blowing air.

[0044] Further, the first sleeve 7 is fixedly sleeved on the main pipe 2, and the horn-shaped cover 8 is connected to the first sleeve 7 to play a protective role on the first branch pipe 3, the main suction cup 4, the second branch pipe 5 and the sub-suction cup 6;

[0045] The main suction cup 4 and the sub-suction cup 6 both extend out of the horn-shaped cover 8, so that the work of the main suction cup 4 and the sub-suction cup 6 is not affected.

[0046] Further, the diameter of the main suction cup 4 is greater than the diameter of the sub-suction cup 6 to reasonably arrange the distribution of the adsorption points and better perform the suction operation on different parts of the stamping part.

[0047] Further, the main suction cup 4 is connected and connected with the first branch pipe 3 by setting the first hose 9, and the sub-suction cup 6 is connected and connected with the second branch pipe 5 by setting the second hose 10.

[0048] Specifically, generally, the suction cup is rigidly connected with the air pipe, so that the orientation of the suction cup when sucking the stamping part is changed, causing the air pipe to also need to change the angle, causing the disadvantage in use operation. The suction and grabbing mechanism of the device is composed of a main suction cup 4 and a plurality of auxiliary suction cups 6, and is respectively sucked on different positions of the stamping part, and is suitable for special-shaped stamping parts, such as arc-shaped workpieces. If the main suction cup 4 and the plurality of auxiliary suction cups 6 are all in the same plane and are rigidly connected with the air pipe, they cannot be all sucked on the arc-shaped workpiece. The device is designed to have the air pipe, that is, the first branch pipe 3 and the second branch pipe 5 are connected with the main suction cup 4 and the auxiliary suction cup 6 through the first hose 9 and the second hose 10 respectively, so that the suction surface of the main suction cup 4 and the plurality of auxiliary suction cups 6 can change the angle, so that the device can suck the special-shaped surface such as the arc-shaped workpiece, that is, the main suction cup 4 and the plurality of auxiliary suction cups 6 can be simultaneously sucked on the special-shaped surface such as the arc-shaped workpiece, so that the device is more flexible and stable in sucking different shapes and sizes of stamping parts.

[0049] Further, the first branch pipe 3 is fixedly sleeved with a second sleeve ring 11, and the second sleeve ring 11 is connected with a first limiting cover 12 for limiting the swing angle of the main suction cup 4, so as to avoid that the main suction cup 4 cannot stably suck the stamping part after excessive swing after air conduction;

[0050] The main suction cup 4 extends out of the first limiting cover 12, and the first hose 9 is located in the first limiting cover 12, so that the first limiting cover 12 limits the rotation angle of the main suction cup 4 without affecting the normal work.

[0051] Further, the second branch pipe 5 is fixedly sleeved with a third sleeve ring 13, and the third sleeve ring 13 is connected with a second limiting cover 14 for limiting the swing angle of the auxiliary suction cup 6, so as to avoid that the auxiliary suction cup 6 cannot stably suck the stamping part after excessive swing after air conduction;

[0052] The auxiliary suction cup 6 extends out of the second limiting cover 14, and the second hose 10 is located in the second limiting cover 14, so that the second limiting cover 14 limits the rotation angle of the auxiliary suction cup 6 without affecting the normal work.

[0053] In the design, the lengths of the first hose 9 and the second hose 10 are not too long, so as to avoid that the main suction cup 4 and the auxiliary suction cup 6 excessively swing, and also avoid that the first hose 9 and the second hose 10 are flattened by negative pressure during air suction and cannot conduct air. At the same time, the first hose 9 and the second hose 10 cannot be completely shortened under the limitation of the first limiting cover 12 and the second limiting cover 14, so as to ensure normal work.

[0054] Further, the end positions of the main suction cup 4 and the auxiliary suction cup 6 are provided with soft rubber rings 15, which directly contact the surface of the stamping part, so as to further improve the applicability of the device to the special-shaped surface of the special-shaped workpiece, so as to improve the sucking stability.

[0055] In summary, the device uses the suction cup to suck the stamping part, and by setting the main suction cup and the auxiliary suction cup, multiple suction points are formed on the suction surface, so that different shapes and sizes of stamping parts can be sucked, safety risks caused by manual operation are avoided, the structure is simple, the use cost is low, and the device is suitable for popularization and use.

[0056] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the present application.
