Description

Technical Field

[0001] The invention relates to the technical field of light and thin product transfer, and in particular to a rotary material-taking clamping claw mechanism. Background Art

[0002] Industrial automation technology continues to improve, and the replacement time of scientific and technological products is shortened, which in turn puts forward higher requirements for industrial automation production equipment. The existing clamping mechanism or suction cup mechanism completes the transfer and positioning of thin products through direct adsorption transfer or clamping transfer by the clamp. In the actual process, whether it is adsorption transfer or clamping transfer, for the production of precision equipment, it will cause slight deviations during the transfer process. Therefore, when operating in subsequent workstations, additional precise positioning is required, which makes the operation cumbersome. For this reason, it is urgently necessary to develop a material-grabbing mechanism that can perform precise positioning and transfer. Summary of the invention

[0003] In response to the above problems, the present invention provides a rotating material picking clamp mechanism, which can reliably adsorb and clamp the product after the entire mechanism runs to the corresponding workstation, thereby ensuring the accurate positioning of the product after it is transferred to the designated position, so that subsequent workstations can be operated directly, thereby improving production efficiency.

When the suction cups adsorb products, the upper surface of the product is tightly against the lower surface of the bottom plate mechanism, and the clamping ends of the two groups of the clamping claw rods are arranged on the relatively outer sides of the bottom plate mechanism;

[0016] After adopting the above technical scheme, after the entire mechanism is transferred to the corresponding workstation, a pair of clamping claws or suction cup assemblies successively perform clamping or adsorption operations, and the sequence of the two actions can be adjusted arbitrarily according to the setting to ensure that the upper surface of the adsorbed product is close to the lower surface of the bottom plate mechanism, and the product cannot be moved after being clamped by the clamping claws. After that, the external power mechanism is fixed to the mechanical arm, thereby driving the entire mechanism to rotate and transfer to the set workstation, and the gas source can be turned off to reliably put down the product; after the entire mechanism runs to the corresponding workstation, it can reliably adsorb and clamp the product, thereby ensuring the precise positioning of the product after being transferred to the position, so that the subsequent workstations can be directly operated, thereby improving production efficiency.

[0025] The clamping jaw assembly 50 includes a pair of clamping jaws 51, each clamping jaw 51 includes a clamping jaw rod 511 and a driving rod 512, and each set of driving rods 512 corresponds to a compression spring 52, a clamping jaw pressing cylinder 53, and a cylinder sensor 54;

[0026] In a specific implementation, the connecting side frame 13 includes a vertical plate 131, a bottom plate 132, and a side convex end 133. The bottom of the vertical plate 131 is provided with a bottom plate 132 bent inwardly, and the middle and lower part of the vertical plate 131 in the height direction is provided with a side convex end 133 protruding outwardly. The vertical plate 131 is provided with an avoidance notch groove 134 in the area corresponding to the side convex end 133, and the avoidance notch groove 134 is connected to the middle of the width of the side convex end 133.

[0027] The bent connection position of the clamping claw rod 511 and the driving rod 512 is pivotally connected to the side convex end 133 of the side frame 13 through the rotating shaft 55. The clamping claw pressing cylinder 53 is fixed to the upper part of the inner wall of the side frame 13. The lower convex moving end 531 of the clamping claw pressing cylinder 53 is pressed and attached to the upper surface of the driving rod 512. The notch groove 134 is avoided to make the installation of the clamping claw 51 simple and convenient. The bottom plate 132 connected to the side frame 13 is provided with a compression spring 52, and the top of the compression spring 52 is mounted on the lower surface of the driving rod 512.

[0028] The upper end of the connecting column 32 of the material pressing plate assembly 30 is fixedly connected to the corresponding installation position of the base 11, the bottom plate mechanism 31 is arranged parallel to the lower surface of the base 11, the inner cavity of the base 11 is provided with an air cavity, the base 11 is fixedly provided with a plurality of downwardly convex suction cups 41, the suction cups 41 penetrate the corresponding through holes of the bottom plate mechanism 31, when the suction cups 41 adsorb the product 70, the upper surface of the product 70 is closely attached to the lower surface of the bottom plate mechanism 31, and the clamping ends of the two sets of clamping claw rods 511 are arranged on the relatively outer sides of the bottom plate mechanism 31;

[0029] The mechanical arm 20 is fixedly connected to the upper end of the central stand 12 via a connecting joint 21 , and an external power mechanism is fixedly connected to the mechanical arm 20 , thereby driving the entire mechanism to rotate and transfer positions.

[0030] The clamping jaw pressing cylinder 53 is also integrated with a cylinder sensor 54, which is used to sense whether the clamping jaw pressing cylinder 53 is pressed down to a certain position, thereby ensuring that the pair of clamping jaws 51 can reliably clamp the product 70;

[0032] Its working principle is as follows: the identification barcode scanning gun 60 determines whether there is a product 70 at the corresponding workstation and whether it is placed correctly. Each suction cup 41 of the suction cup assembly 40 works simultaneously to absorb the product 70, and the clamp 51 is pressed down by the clamp pressing cylinder 53 to adjust the position of the clamped and fixed product 70. After that, the external power mechanism is fixed to the mechanical arm 20, thereby driving the entire mechanism to rotate and transfer to the set position. After turning off the air source, the product 70 can be reliably lowered. When the product 70 is lowered, due to the presence of the compression spring 52, the clamp 51 directly separates from the product 70 without causing disturbance. After the entire mechanism runs to the corresponding workstation, it reliably absorbs and clamps the product, thereby ensuring the precise positioning of the product after transfer, so that the subsequent workstations can be directly operated, thereby improving production efficiency.
