[0027] As Figures 1-5 shown, a clamping and material-taking mechanism includes a frame 10, a driving module 20 provided on the frame 10, and a finger cylinder 30 provided on the driving module 20. A first clamping jaw 31 and a second clamping jaw 32 that can move relative to each other are provided at the driving end of the finger cylinder 30. Silicone pads 33 are provided on the opposite sides of the first clamping jaw 31 and the second clamping jaw 32.

[0028] The driving module 20 includes a first driving component 21 provided on the frame 10, a second driving component 22 provided on the first driving component 21, and a third driving component 23 provided on the second driving component 22. The finger cylinder 30 is provided on the third driving component 23. By providing the first driving component 21, the second driving component 22, and the third driving component 23, the finger cylinder 30 has multiple degrees of freedom of movement and is suitable for multi-directional clamping and material-taking.

[0029] The first driving component 21 can drive the second driving component 22 to move horizontally in a straight line. The second driving component 22 can drive the third driving component 23 to move up and down. The third driving component 23 can drive the finger cylinder 30 to rotate horizontally. Specifically, the first driving component 21 is a rodless cylinder, the second driving component 22 is a lifting cylinder, and the third driving component 23 is a rotary cylinder. It can be understood that the rodless cylinder can also be replaced by a driving structure of a synchronous belt + motor, and the rotary cylinder can also be replaced by a rotary motor.

[0030] A number of elastic connecting columns 331 perpendicular to the silica gel pad 33 are formed on the silica gel pad 33. Exemplarily, the number of the elastic connecting columns 331 is four. Elastic clamping blocks 332 protruding radially outward are formed on the elastic connecting columns 331. A distance c1 is maintained between the elastic clamping blocks 332 and the silica gel pad 33. On the sides of the first clamping jaw 31 and the second clamping jaw 32 away from the silica gel pad 33, clamping grooves 321 corresponding to the elastic clamping blocks 332 one by one are provided. Through holes 322 for the elastic connecting columns 331 to pass through are provided in the clamping grooves 321. The diameter d2 of the through holes 322 < the diameter d3 of the elastic clamping blocks 332. The elastic clamping blocks 332 are clamped with the clamping grooves 321.

[0031] The sum b1 of the depths of the through holes 322 and the clamping grooves 321 < the sum b2 of the distances between the elastic clamping blocks 332 and the ends of the elastic connecting columns 331 away from the silica gel pad 33. During assembly, first, the ends of the elastic connecting columns 331 away from the silica gel pad 33 are sequentially passed through the through holes 322 and the clamping grooves 321 and extend outwards. Then, the elastic connecting columns 331 are pulled outwards in the direction away from the silica gel pad 33. The elastic connecting columns 331 and the elastic clamping blocks 332 will both produce elastic deformation, with the size reduced and stretched, so that the elastic clamping blocks 332 pass through the through holes 322 and are clamped in the clamping grooves 321, and thus the assembly of the silica gel pad 33 to the first clamping jaw 31 or the second clamping jaw 32 can be completed, and the assembly is convenient.

[0032] The diameter d1 of the elastic connecting columns 331 < the diameter d2 of the through holes 322; by setting the diameter of the elastic connecting columns 331 < the diameter of the through holes 322, when the elastic connecting columns 331 pass through the through holes 322, there is a gap between the elastic connecting columns 331 and the through holes 322, thus facilitating the elastic connecting columns 331 to pass through the through holes 322 and extend outwards.

[0033] The distance c1 < the length c2 of the through holes 322 along their own axial directions, so that after the silica gel pad 33 is assembled, the first clamping jaw 31 is tightly and matingly connected with the silica gel pad 33 and the elastic clamping blocks 332, and the second clamping jaw 32 is tightly and matingly connected with the silica gel pad 33 and the elastic clamping blocks 332; by setting the distance c1 between the elastic clamping blocks 332 and the silica gel pad 33 < the length c2 of the through holes 322 along their own axial directions, thus after assembly, the first clamping jaw 31 is tightly and matingly connected with the silica gel pad 33 and the elastic clamping blocks 332, and the second clamping jaw 32 is tightly and matingly connected with the silica gel pad 33 and the elastic clamping blocks 332, making the assembly of the silica gel pad 33 more stable and avoiding loosening.

[0034] On the outer edge of the end of the elastic clamping block 332 away from the silica gel pad 33, a chamfer 333 is provided. The chamfer 333 is an inclined chamfer or a rounded chamfer. Preferably, the chamfer 333 is an inclined chamfer; by providing the chamfer 333 on the elastic clamping block 332, with the guiding effect, it is easy for the elastic clamping block 332 to smoothly pass through the through hole 322 and enter the clamping groove 321, and the assembly is convenient.

[0035] On the opposite sides of the first clamping jaw 31 and the second clamping jaw 32, positioning grooves 323 are provided. The positioning grooves 323 are connected to the through holes 322. The silica gel pad 33 is embedded in the positioning grooves 323, and the inner surface of the silica gel pad 33 protrudes outside the positioning grooves 323. By providing the positioning grooves 323, the silica gel pad 33 can be positioned, improving the assembly accuracy.

[0036] On the inner surface of the silica gel pad 33, a plurality of anti-slip protrusions (not shown) are distributed. The plurality of anti-slip protrusions are arranged in a matrix. The anti-slip protrusions are hemispherical, and the diameter of the anti-slip protrusions is 0.5 mm - 1 mm. By providing the anti-slip protrusions, the anti-slip protrusions can increase the friction with the head on the product 40, thereby preventing slipping and improving the clamping stability.

[0037] In summary, in the present utility model, a number of elastic connecting columns 331 perpendicular to the silica gel pad 33 are formed on the silica gel pad 33, and elastic clamping blocks 332 protruding radially outward are formed on the elastic connecting columns 331. A distance c1 is maintained between the elastic clamping blocks 332 and the silica gel pad 33. And on the sides of the first clamping jaw 31 and the second clamping jaw 32 away from the silica gel pad 33, clamping grooves 321 corresponding to the elastic clamping blocks 332 one by one are provided. Through holes 322 for the elastic connecting columns 331 to pass through are provided in the clamping grooves 321, and the diameter of the through holes 322 < the diameter of the elastic clamping blocks 332. During assembly, the elastic connecting columns 331 are passed through the through holes 322 and the clamping grooves 321, and the elastic clamping blocks 332 are elastically deformed to pass through the through holes 322 and be clamped into the clamping grooves 321, then the clamping connection between the silica gel pad 33 and the first clamping jaw 31 / the second clamping jaw 32 can be completed. Thus, by adopting the clamping connection method, the connection structure between the silica gel pad 33 and the first clamping jaw 31 / the second clamping jaw 32 is simplified, and the assembly is more convenient.

[0038] The above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
