[0025] Embodiment 1

[0027] In the present embodiment, a suction clamping device is provided, wherein the first driving assembly 4 drives the driving block 52 to move along the guide rod 51 toward the suction port 57, at which time the first elastic member 54 contracts, the second elastic member 55 compresses, and the clamping end of the clamping member 53 rotates in a direction away from each other, and then the suction port 57 of the guide rod 51 adsorbs the material 7, and finally the output end of the first driving assembly 4 moves away from the driving block 52, at which time the second elastic member 55 drives the driving block 52 to move along the guide rod 51 away from the suction port 57, the first elastic member 54 expands, and the clamping end of the clamping member 53 rotates in a direction close to each other until the material 7 is clamped and positioned. By setting the driving block 52 on the guide rod 51, the first elastic member 54 on the two clamping members 53, and the second elastic member 55 between the driving block 52 and the stopper 56, the transmission mechanism of the clamping member 53 to complete the clamping or opening action occupies a smaller volume, and at the same time, the two clamping members 53 clamp and position the material 7 to improve the position accuracy of the material 7 after adsorption.

[0028] Reference Figure 1 As shown, the first driving assembly 4 includes a first driving member 41, a driving rod 43 and a fixing block 42. The fixing block 42 is fixed to the outside. The first driving member 41 can be regarded as a cylinder. One end of the driving rod 43 is hinged to the output end of the first driving member 41. The middle position of the driving rod 43 is hinged to the fixing block 42. The end of the driving rod 43 away from the first driving member 41 extends toward the driving block 52 and abuts against the driving block 52. Through the transmission mode of the driving rod 43 and the fixing block 42 being hinged, the first driving member 41 is driven at a position away from the guide shaft, so as to avoid the first driving member 41 occupying the space near the clamping adsorption assembly 5.

[0029] Reference Figure 2 and Figure 3As shown, the clamping and adsorption assembly 5 includes a guide rod 51, a clamping member 53 and a driving block 52. An adsorption port 57 is provided at one end of the guide rod 51 away from the first driving member 41, and the adsorption port 57 is connected to an external vacuum source. The driving block 52 is sleeved on the guide rod 51 and slidably connected to the guide rod 51. A stopper 56 is connected to the position of the guide rod 51 close to the adsorption port 57. At least two clamping members 53 are hinged to the stopper 56. In this embodiment, there are two clamping members 53 in total, and different numbers of clamping members 53 can be set according to the material 7. One end of the clamping member 53 close to the adsorption port 57 is a clamping end. The adsorption port 57 is located between the clamping ends of the two clamping members 53. The clamping end protrudes from the plane where the adsorption port 57 is located on the guide rod 51, so that the clamping end can clamp the adsorbed material 7. One end of the driving rod 43 away from the first driving member 41 abuts against one end of the driving block 52 away from the adsorption port 57.

[0030] The clamping members 53 are arranged along the guide rod 51, and the ends of the two clamping members 53 away from the suction port 57 are sleeved with a first elastic member 54, which can be regarded as a rubber ring. Specifically, the outer walls of the two clamping members 53 are provided with a first slot 531, and the bottom of the first slot 531 is arc-shaped. The first elastic member 54 is clamped at the bottom of the first slot 531. The side wall of the driving block 52 is provided with a second slot 521, and the bottom of the second slot 521 is arc-shaped to fit the first elastic member 54. The first elastic member 54 is clamped with the second slot 521, and the width of the second slot 521 is greater than the thickness of the first elastic member 54, so that the driving block 52 can slide along the guide rod 51 while the first elastic member 54 can slide in the second slot 521, thereby avoiding interference between the first elastic member 54 and the driving block 52.

[0031] A second elastic member 55 is provided between the driving block 52 and the stopper 56 . The second elastic member 55 can be regarded as a spring. The second elastic member 55 is sleeved on the guide rod 51 , and two ends of the second elastic member 55 are respectively against the stopper 56 and the driving block 52 .

[0032] The driving block 52 is located between the two clamping members 53 and abuts against the clamping members 53. Specifically, guide grooves 532 are provided on the opposite sides of the two clamping members 53. The distance between the bottoms of the guide grooves 532 gradually decreases toward the first driving assembly 4, that is, the two guide grooves 532 can form a dovetail groove. The driving block 52 includes a protrusion 522 abutting against the side wall of the guide groove 532. The distance between the end of the clamping member 53 away from the suction port 57 can be adjusted by the movement of the driving block 52, that is, the movement of the driving block 52 can drive the clamping member 53 to rotate, so that the driving block 52 can drive the clamping ends of the two clamping members 53 to move in a direction close to or away from each other. Preferably, the driving block 52 is matched with the size of the guide groove 532, that is, the side wall of the driving block 52 is in contact with the oblique side wall of the guide groove 532, so that the contact area between the driving block 52 and the guide groove 532 is larger, and the rotation of the clamping member 53 is more stable.

[0033] When in use, the output end of the first driving member 41 retracts to drive the driving rod 43 to press down the driving block 52, and the driving block 52 moves along the guide rod 51 toward the direction close to the suction port 57. At this time, the second elastic member 55 is compressed, and the first elastic member 54 contracts, thereby driving the clamping end of the clamping member 53 to rotate in a direction away from each other, and then the suction port 57 of the guide rod 51 adsorbs the material 7. After the adsorption is completed, the output end of the first driving member 41 extends, so that the driving rod 43 stops pressing down the driving block 52, and the second elastic member 55 drives the driving block 52 to move along the guide rod 51 away from the suction port 57, the first elastic member 54 expands, and the clamping end of the clamping member 53 rotates in a direction close to each other until the adsorbed material 7 is clamped and positioned.

[0037] Reference Figure 5As shown, the transmission assembly 3 includes a first movable seat 32 and a second movable seat 35, both of which are slidably connected to the first connecting plate 31 through a slider and a slide rail, and the first movable seat 32 and the second movable seat 35 are slidably connected to the same slide rail, and the sliding paths of the first movable seat 32 and the second movable seat 35 are parallel to the guide rod 51. The first connecting plate 31 is connected to the support plate 1, and the output end of the second driving member 2 is connected to the first movable seat 32. Specifically, a movable nut that cooperates with the lead screw is provided in the first movable seat 32, so that the second driving member 2 can drive the first movable seat 32 to move.

[0038] A first detection member 39 is connected between the first movable seat 32 and the second movable seat 35, so that the first movable seat 32 is connected to the second movable seat 35. The first detection member 39 can be regarded as a weighing sensor, and the first detection member 39 is connected to the controller. The first movable seat 32 is also connected to a sensing member 33, which is L-shaped and extends toward the support plate 1. The support plate 1 is provided with a second detection member 34 connected to the control, and the detection end of the second detection member 34 faces the moving path of the sensing member 33. The second detection member 34 is used to locate the position of the second detection member 34, that is, the second detection member 34 can locate the position of the first movable seat 32.

[0039] The second movable seat 35 is connected to the first driving member 41 and the guide rod 51 in the adsorption clamping device. The first driving member 41 is located at the top of the second movable seat 35. The guide rod 51 is vertically connected to the bottom of the second movable seat 35. A joint is provided at the top of the second movable seat 35. The joint is connected to the internal channel of the guide rod 51, that is, the joint is connected to the adsorption port 57 of the guide rod 51. The output end of the first driving member 41 passes through the second movable seat 35. The fixed block 42 is connected to the bottom of the second movable seat 35 and is located between the guide rod 51 and the output end of the first driving member 41. The second driving member 2 drives the second movable seat 35 to move by driving the first movable seat 32 to move, thereby driving the adsorption clamping device to move. The second driving member 2 drives the adsorption clamping device to move, so that the adsorption end of the guide rod 51 is against the material 7. In the process of the adsorption end of the guide rod 51 against the material 7, the weighing sensor can detect the pressure on the adsorption end of the guide rod 51, thereby judging whether the adsorption end of the guide rod 51 is completely in contact with the material 7.

[0040] The side wall of the first movable seat 32 is also connected to a second connecting plate 36, which extends along the sliding direction of the first movable seat 32. The second connecting plate 36 is provided with a slide groove 37. The second movable seat 35 is provided with a protrusion 38. The protrusion 38 is slidably connected to the slide groove 37, so that the second movable seat 35 can slide along the slide groove 37.

[0044] When in use, the transfer mechanism drives the support plate 1 to move to the material 7 picking position, and the second driving member 2 drives the second movable seat 35 to move until the adsorption end of the guide rod 51 is in contact with the material 7, and then the adsorption and clamping device adsorbs and clamps the material 7, and at the same time the adsorption member 6 adsorbs the material at the corresponding position.
