[0033] As Figures 1 to 6As shown, a glass fiber feeding hand claw includes at least one hand claw device mounted on a mounting plate 5, the hand claw device includes a clamping device 1 and a lifting device 3, the clamping device 1 includes a hand claw cylinder 11 connected to the bottom surface of the mounting plate 5, and the output end of the hand claw cylinder 11 is connected with at least three clamping jaws 12; the lifting device 3 includes a first telescopic cylinder 32 fixed on one side of the mounting plate 5, and the output end of the first telescopic cylinder 32 is connected with at least two first sliding rods 34 through a first connecting plate 33, and the end of the first sliding rod 34 is connected with an arc-shaped lifting frame 35; the center of the circle where the lifting frame 35 is located and the clamping centers of the plurality of clamping jaws 12 are on the same straight line.

[0034] The feeding hand claw designed in the application can realize clamping and loosening of the top end of the yarn cylinder by opening and closing the clamping jaws driven by the hand claw cylinder during the transfer of the yarn cylinder, and can realize lifting of the yarn cylinder by moving the arc-shaped lifting frame to the end of the yarn cylinder through the operation of the first telescopic cylinder. The center of the circle where the lifting frame is located and the clamping centers of the plurality of clamping jaws are on the same straight line, which can ensure effective clamping and lifting of the circular yarn cylinder and ensure the transfer effect of the yarn cylinder. Through the form of mutual action of the two ends, the stress is reasonable, and the service life of the hand claw is ensured.

[0035] Specifically, as shown in the drawings, Figure 1 The yarn cylinder is in the shape of a hollow cylinder plus a circular table, which is convenient for winding of glass fibers. When the yarn cylinder is in the shape of a hollow cylinder plus a circular table, Figure 1 the hand claw designed in the application is as follows. The hand claw includes a clamping device 1 and a lifting device 3, the clamping device 1 is used for clamping the small end of the yarn cylinder, and the lifting device 3 is used for lifting the bottom end of the yarn cylinder, and the two devices act together to ensure stable transfer of the yarn cylinder.

The hand claw cylinder 11 works to drive the clamping jaws 12 to open or close, so as to realize clamping of the small end of the yarn cylinder.

[0037] In order to ensure that the small end of the yarn cylinder can be effectively clamped, the clamping jaws 12 at the output end of the hand claw cylinder 11 of the application can form a circular clamping space, i.e. the three clamping jaws 12 are always located on the same circle center.

[0038] Further, in order to ensure that the clamping jaws will not damage the glass fibers on the yarn cylinder when clamping the yarn cylinder, a buffer pad 13 is further arranged on the clamping surface of the clamping jaw 12.

[0039] In some further embodiments, in order to ensure that the clamping jaw is clamped on the small end of the yarn cylinder and the small end of the yarn cylinder is in a stable state, the application also provides a positioning sleeve 2. Specifically, the bottom surface of the mounting plate 5 is connected with a positioning sleeve connecting ring 21 through three connecting rods 22, the positioning sleeve connecting ring 21 is located below the clamping jaw 12, and the center of the positioning sleeve connecting ring 21 and the center of the circular clamping space formed by the three clamping jaws 12 are on the same straight line. This design ensures that the center of the positioning sleeve 2 and the center of the circular clamping space formed by the three clamping jaws 12 are on the same straight line after the positioning sleeve 2 is installed, so as to ensure that the positioning sleeve 2 has accurate positioning effect.

[0040] When clamping the small end of the yarn cylinder, the whole hand claw device is controlled to move, the positioning sleeve 2 is inserted into the outer periphery of the small end of the yarn cylinder, the conical positioning hole in the positioning sleeve 2 guides and positions the small end of the yarn cylinder, the small end of the yarn cylinder enters the center of the clamping space formed by the clamping jaws, and the clamping jaw 12 is controlled to work, so as to realize clamping and loosening of the small end of the yarn cylinder.

By adjusting the height of the positioning plate 44, the fixing of the small end of the yarn cylinder can be better adapted.

[0042] Further, the second telescopic cylinder 41 is connected to the top surface of the mounting plate 5, the output end of the second telescopic cylinder 41 is connected with a second connecting plate 42, three second sliding rods 43 are connected to the second connecting plate 42, the second sliding rods 43 pass through the sliding seat 45 on the connecting rod 22 and the mounting plate 5, and are connected with the positioning plate 44, so as to drive the positioning plate 44 to move up and down in a small range.

[0043] Further, in order to prevent the positioning plate 44 from moving downward excessively, the application also connects a limiting block 46 to the top surface of the positioning sleeve 2, so as to limit the positioning plate 44.

Specifically, the top surface of the mounting plate 5 is connected with a mounting frame 31, the top end of the first telescopic cylinder 32 is fixedly connected with the mounting frame 31, and the bottom end of the first telescopic cylinder 32 is fixed to the outside of the positioning sleeve connecting ring 21. The top end of the first telescopic cylinder 32 is an output end, the output end of the first telescopic cylinder 32 is connected with a first connecting plate 33 through a connecting plate on the mounting frame 31; the output end of the first telescopic cylinder 32 is connected with at least two first sliding rods 34 through the first connecting plate 33, the first sliding rods 34 are slidingly connected with the connecting plate on the mounting frame 31 and the positioning sleeve connecting ring 21, and the distal ends of the first sliding rods 34 are connected with arc-shaped lifting frames 35.

[0045] Through the design, the first slide rod 34 has sufficient extension length, and the lifting frame 35 can be lifted to the large end of the yarn drum, and the lifting frame 35 can be retracted in place when the yarn drum is transported.

[0046] Further, in order to prevent the lifting frame 35 from damaging the glass fiber on the yarn drum when the yarn drum is lifted, a buffer pad is further connected to the inner lifting surface of the lifting frame 35.

[0047] In some embodiments, as shown in Figure 6 three yarn drums can be simultaneously transported, and further, the top surface of the mounting plate 5 is further connected with a connecting seat 6, so as to realize the connection of the mechanical arm, and facilitate the control of the gripper device.
