[0047] Figure 1 It is a schematic diagram of the structure of the rod transfer equipment. Figure 1 As shown, the rod transfer device includes a frame 10, a gripper mechanism 20, a swing mechanism 30, a transmission mechanism 40 and a push rod mechanism 50. The frame 10 is generally in the shape of a frame body, and is used to support other mechanisms or components. After the gripper mechanism 20 grabs the rod 60, the swing mechanism 30 drives the gripper mechanism 20 to move to the target position and then releases the rod 60 to the transmission mechanism 40. After the transmission mechanism 40 transmits the rod 60 to the target position, the rod 60 is pushed out of the transmission mechanism 40 by the push rod mechanism 50, and the transfer of the rod 60 is completed. In the present application, the rod 60 can be solid or a hollow tube.

[0048] Figure 2 Schematic diagram of the structure of the gripper mechanism 20 of the rod transfer device. Figure 2As shown, the gripper mechanism 20 includes a gripper seat 21 and a gripper 22. In this embodiment, the gripper seat 21 is generally an "N"-shaped frame structure, and the number of the gripper 22 is two, extending in the vertical direction, and the end (top end) connected to the gripper seat 21 is hinged to the gripper seat 21. The bottom end of the gripper 22 is provided with a relative opening groove, and is connected to a driving cylinder, and is driven by the driving cylinder to open or close the gripper to grasp the rod 60 or release the rod 60.

[0049] Figure 3 3 is a schematic diagram of the structure of the swing mechanism 30 of the rod transfer device. Figure 3 The swing mechanism 30 includes a swing rod 32, a swing cylinder 31 and a lifting cylinder 33. In this embodiment, there are two swing rods 32, which are arranged parallel to each other in the vertical direction. The bottom end of the swing rod 32 is hinged to the frame 10, and the top end is hinged to the bottom of the gripper seat 21. One end of the swing cylinder 31 is hinged to the frame 10, and the other end is hinged to the middle of the swing rod 32. When the swing cylinder 31 is extended or retracted, the swing rod 32 can be driven to swing back and forth.

[0050] Figure 4 3 is a schematic diagram of the structure of the lifting cylinder 33 and the swing rod 32. Figure 4 As shown, the lifting cylinder 33 is generally arranged in the vertical direction, one end of which is connected to the frame 10, and the other end is hinged to the lifting block 321. The lifting block 321 is connected to the side wall of the swing rod 32, and the side facing the lifting cylinder 33 is an inclined surface, which is used to support the swing rod 32 when the swing rod 32 swings, thereby improving the acceptance balance of the swing rod 32.

[0051] Figure 5 Schematic diagram of the structure of the transmission mechanism 40. Figure 5 As shown, the transmission mechanism 40 includes a pair of transmission wheels 41, a transmission chain 42 and a plurality of brackets 43. In this embodiment, the pair of transmission wheels 41 are sprocket wheels, which are rotatably connected to the two ends of the frame 10. The transmission chain 42 is a chain, which passes around the pair of transmission wheels 41 and is used to drive the pair of transmission wheels 41 to rotate synchronously.

[0052] Figure 6 43 is a schematic diagram of the structure of the bracket. Figure 6As shown, the bracket 43 is open at the top and through at both ends, and a connecting hole is provided at the bottom for connecting to the conveying chain 42 through a connecting piece. After the gripper 22 releases the rod 60, the rod 60 falls from the opening at the top of the bracket 43 into the bracket 43 to support the rod 60. In some preferred embodiments, a guide portion 431 is provided at the top of the bracket 43, and the guide portion 431 is relatively inclined outward to guide the rod 60 into the bracket 43, so that the rod 60 enters the opening at the top of the bracket 43 under the guidance of the guide portion 431.

[0053] Figure 7 Schematic diagram of the structure of the push rod mechanism 50. Figure 7 As shown, the push rod mechanism 50 includes a push rod cylinder 51, a push frame 54, a slide 53 and a push plate 52. The slide 53 is fixed on the frame 10 and has three through holes that penetrate in the horizontal direction. The push rod cylinder 51 is fixedly connected to the slide 53, and the output shaft of the push rod cylinder 51 extends from a through hole of the slide 53 and connects the push plate 52. The push frame 54 includes two push rods 541 and a connecting portion 542, and the push rods 541 are respectively connected to the connecting portion 542 to form a "U"-shaped structure, and one end of the two push rods 541 passes through the through hole of the slide 53 and is connected to the push plate 52 and the output shaft of the push rod cylinder 51. The push rod cylinder 51 is located between the push rods 541, so as to prevent the stroke of the push rod cylinder 51 from being too large. When the stroke exceeds a preset value, the connecting portion 542 of the push frame 54 contacts the push rod cylinder 51 and stops. The push plate 52 is generally in a flat plate structure, and a plurality of push forks 521 extending downward are provided at the end thereof. The width of the push forks 521 is less than or equal to the inner diameter of the push frame 54, and the push plate 52 is connected to the output shaft of the push rod cylinder 51. In this way, under the drive of the push rod cylinder 51, the push forks 521 can be pushed to move back and forth along the length direction of the bracket 43, thereby pushing the rod 60 out of the bracket 43.

[0054] The following describes in detail a rod transfer method for transferring the rod 60 using the rod transfer device according to the above embodiment.

[0055] In this embodiment, the rod 60 is placed at the original position, and the rod 60 is automatically transferred to the target position by the rod transfer device.

[0056] First, when the swing cylinder 31 is extended, the swing rod 32 is driven to swing, so that the gripper mechanism 20 moves to the first position following the swing rod 32. At this time, the gripper 22 of the gripper mechanism 20 moves to the top of the rod 60 around an arc with the swing rod 32 as the radius;

[0057] Then, the gripper 22 of the gripper mechanism 20 grips the rod 60 . At this time, the rod 60 is clamped by the gripper 22 and can move with the gripper 22 .

[0058] Then, the swing cylinder 31 contracts, driving the swing rod 32 to swing so that the gripper mechanism 20 moves to the second position following the swing rod 32. At this time, the gripper 22 moves above the bracket 43 of the conveying mechanism 40 following the swing rod 32.

[0059] Then, the gripper 22 of the gripper mechanism 20 releases the rod 60 so that the rod 60 falls into the bracket 43 of the conveying mechanism 40 to transfer the rod 60 .

[0060] The above steps achieve the purpose of transferring the rod 60 from the original position to the transmission mechanism 40. In some embodiments, the rod transfer method may further include the following steps.

[0061] After the rod 60 falls into the bracket 43 of the conveying mechanism 40 , a pair of conveying wheels 41 of the conveying mechanism 40 drives the bracket 43 to move through the conveying chain 42 to transfer the rod 60 until the rod 60 follows the bracket 43 to move to the target position.

[0062] Then, the push rod cylinder 51 of the push rod mechanism 50 drives the push plate 52 to move along the length direction of the bracket 43 to push the rod 60 out of the bracket 43 , thereby realizing the transfer function of the rod 60 .

[0063] The above-mentioned rod transfer equipment and transfer method push the rocker arm 32 through the swing cylinder 31 so that the gripper mechanism 20 follows the rocker arm 32 to move to the initial position, and the gripper 22 grabs the rod 60. When the swing cylinder 31 pulls back the rocker arm 32 so that the gripper mechanism 20 follows the rocker arm 32 to move to the target position, the gripper 22 releases the rod 60, thereby automatically realizing the transfer of the rod 60, effectively improving the production and processing efficiency of the rod 60.

[0064] In the several specific embodiments provided by the present invention, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
