In order to improve the reliability of the inclined beam 51 during work, a supporting beam 53 is arranged between the end of the inclined beam 51 away from the rotating shaft 52 and the rotating shaft 52. In the working process, the feeding unit 3 takes out the workpiece after galvanizing from the galvanizing pool 2 and places it on the discharge conveying frame, in this process, the rotating shaft of the auxiliary placement frame 5 is first rotated to the first limit position, so that the end of the inclined beam 51 away from the rotating shaft 52 is at the highest point, the feeding unit 3 places the workpiece at the bottom into the V-shaped space 54, so that the workpiece is inclined and leans on the inclined beam 51, then the rotating shaft 52 rotates to the second limit position, so that the highest point of the inclined beam 51 is lowered, and then the workpiece is placed on the conveying roller, and the workpiece is transported to the next station through the rotation of the conveying roller.

[0040] The feeding unit 3 comprises a gripper capable of moving in the vertical direction, the gripper comprising at least two gripper legs capable of extending into the resting space 213 and the storage space when the gripper moves to the lower limit position. Specifically, in the embodiment, the two gripper legs are divided into a fixed gripper leg 32 and a rotating gripper leg 31, the rotating gripper leg 31 being capable of rotating about its length direction, and the rotating gripper leg 31 extending outward at one end to form a clamping head 311, the fixed gripper leg 32 and the rotating gripper leg 31 leaving a clamping space 33 therebetween, and one end of the clamping space 33 being provided with an opening 34; when the rotating gripper leg 31 rotates to the limit position, the clamping head 311 is placed in the clamping space 33, and when the rotating gripper leg 31 rotates to the second limit position, the clamping space 33 is in communication with the outside through the opening 34. In the embodiment, the rotating gripper leg 31 and the fixed gripper leg 32 are respectively fixed on a hanger 35, the hanger 35 being connected with a walking unit, and the walking unit is further provided with a lifting machine for controlling the lifting movement of the hanger 35, which can be a scissor lifting machine or other lifting machines such as a screw rod lifting machine, and the specific structure and arrangement of the lifting machine are prior art in the field, which will not be described herein. In the embodiment, the hanger 35 comprises a main body 351 and a supporting leg 352 extending outward from the main body 351, one end of the rotating gripper leg 31 being rotatably connected with the main body 351, and one end of the fixed gripper leg 32 being rotatably connected with the supporting leg. The main body 351 is a square tube, and a rotary motor can be arranged in the square tube to drive the rotating gripper leg 31 to rotate, and the top end of the rotating gripper leg 31 is fixedly connected with the output shaft of the rotary motor, so that the rotating gripper leg 31 is driven to rotate within a range of 90° through the motor, or a motor can be arranged on the top of the hanger 35 to drive the rotating gripper leg 31 to rotate through a transmission structure. The end of the fixed gripper leg 32 close to the opening 34 extends an insertion head 321 along the length direction of the fixed gripper leg 32, the width of the insertion head 321 being smaller than the width of the fixed gripper leg 32, so as to facilitate the fixed gripper leg 32 to extend to the side of the workpiece in the resting space 213 and the storage space, and a transition edge 322 is arranged between the insertion head 321 and the outer edge of the rotating gripper leg 31, so that when two workpieces are adjacent or close to each other, the insertion head 321 can extend into the gap between the two workpieces, and the transition edge 322 can guide the workpiece on the outside outward, thereby avoiding the influence of the bending of the two workpieces on the workpiece that should be rested when the workpiece is lifted. The end of the rotating gripper leg 31 and the fixed gripper leg 32 away from the opening 34 extends a reinforcing portion 312 along the width direction of the rotating gripper leg 31 and the fixed gripper leg 32, the width of the reinforcing portion 312 being greater than the width of the rotating gripper leg 31, so as to improve the strength of the two gripper legs and avoid the workpiece from falling due to shaking during the clamping and transferring of the workpiece.

[0041] In the embodiment, the clamping head 311 comprises a clamping surface 311a and a pulling surface 311c, and the clamping surface 311a corresponds to the fixed clamping leg 32 when the rotating clamping leg 31 rotates to the first limit position. The pulling surface 311c is inclined towards the upper side, and the pulling surface 311c faces the inside of the clamping space 33 when the rotating clamping leg 31 rotates to the first limit position.

[0042] In other embodiments, the clamping head 311 comprises a receiving slot, and the shape of the receiving slot is similar to the cross section of the outward protruding part of the workpiece to be clamped, so that the protruding part of the workpiece can be clamped in the receiving slot during the rotation of the rotating clamping leg 31, and the opening 34 of the receiving slot faces the fixed clamping leg 32 at this time. In the working process, the walking unit drives the clamping jaw to move above the wave-shaped beam plate to be grabbed, and then the lifter controls the clamping jaw to move downward until the clamping jaw extends into the storage space or the stationary space where the wave-shaped beam plate to be grabbed is located. In this process, the insertion head 321 first extends from one side of the wave-shaped beam plate, and when the distance between the two wave-shaped beam plates in the galvanizing pool 2 is too close, the insertion head 321 extends from the position opposite to the partition rod into the galvanizing pool 2, and the outer wave-shaped beam plate is guided outward by the transition edge 322 to avoid the wave-shaped beam plate being galvanized from the galvanizing pool 2 during the grabbing process, which affects the galvanizing effect. At the same time, when the rotating clamping leg 31 rotates to the second limit position, the distance between the rotating clamping leg 31 and the fixed clamping leg 32 is the same as the distance between two adjacent partition rods 212.

[0043] In order to avoid damage to the wave-shaped beam plate caused by the insertion head 321, the width of the insertion head 321 is less than or equal to the width of the partition rod 212. In the embodiment, there are two sets of clamping jaws, one of which moves between the storage space and the galvanizing pool 2, so that when there is a wave-shaped beam plate in the storage space, the clamping jaw can timely grab the wave-shaped beam plate from the storage space, avoiding the accumulation of materials in the storage space and causing trouble for subsequent grabbing.

[0044] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
