The pushing driving assembly is connected with the pushing member 2320 to drive the pushing member 2320 to move along the length direction of the feeding chute, and the pushing member 2320 is used for pushing the workpiece 1110 to move in the feeding chute.

As shown in fig. 7, in the blanking sorting apparatus 140, the processed workpiece 1110 firstly falls into the blanking support 2120, and the blanking support 2120 is inclined and deflected downward after receiving the workpiece 1110, so that the workpiece 1110 moves from the blanking support 2120 to the buffer 2220; the buffer 2220 is inclined and deflected downwards after receiving the workpiece 1110, so that the workpiece 1110 falls into the feeding chute of the pushing mechanism. In the blanking process, the machined workpiece 1110 does not directly fall into the pushing mechanism, but temporarily stores and buffers the workpiece 1110 through the blanking support 2120 and the buffer 2220, and compared with the impact force generated when the workpiece 1110 directly falls into the pushing mechanism, the impact force generated when the workpiece 1110 excessively falls into the pushing groove through the buffer 2220 is greatly reduced, so that the impact damage to the structure of the pushing machine is reduced, and the risk of damage to the machined profile of the workpiece 1110 is also reduced. Specifically, the buffering member 2220 is a V-shaped plate, and when the buffering member 2220 receives the material, the opening faces the blanking support 2120; after the workpiece is received, the buffer 2220 is rotated clockwise so that the opening of the V-shaped plate faces the chute. In other embodiments, the buffer member may also include a first plate and a second plate, the first plate is fixed, and the second plate is rotatably connected to the first plate; when receiving materials, the second plate is vertical to the first plate, so that a workpiece is blocked; after receiving the workpiece, the second plate deflects towards the lower right direction relative to the first plate, so that the workpiece falls into the feeding groove.

As shown in fig. 7, in an embodiment, the blanking support 2120 is provided with a blanking roller 2140, an axial direction of the blanking roller 2140 is parallel to a length direction of the blanking support 2120, and the blanking roller 2140 is used for bearing the workpiece 1110. When the blanking support 2120 is tilted downward, the workpiece 1110 is moved downward and to the right due to the support face being tilted downward. The blanking roller 2140 and the workpiece 1110 are in line contact, and the contact area between the blanking roller 2140 and the workpiece 1110 is reduced, so that the friction force during the movement of the workpiece 1110 is reduced, and the movement resistance is reduced. When the workpiece 1110 moves, the blanking roller 2140 can be driven to rotate clockwise around the axis of the workpiece 1110, the workpiece 1110 is pushed to move downwards and rightwards, the workpiece 1110 can move quickly to the position of the buffer 2220, and the blanking efficiency is improved. In other embodiments, the blanking roller can be driven by the driving piece to rotate clockwise around the axis of the blanking roller, so that the workpiece can move to the target position quickly.

As shown in fig. 7, in a specific embodiment, the feeding groove is a V-shaped groove, and the wall of the V-shaped groove along the width direction thereof can block the workpiece 1110, so as to reduce the risk that the workpiece 1110 rolls out of the groove. Furthermore, a detection pressure plate and a sensor arranged on one side of the detection pressure plate are rotatably connected to the wall of the feeding groove. When the workpiece 1110 falls into the material feeding groove, the workpiece 1110 touches the detection pressure plate under the action of gravity, the detection pressure plate rotates, the sensor can detect the action of the detection pressure plate, the material pushing driving assembly can act at the moment, and the workpiece 1110 is pushed by the material pushing element 2320.

As shown in fig. 8, further, after the workpiece 1110 falls into the feeding chute, a feeding roller 2370 is mounted on the bottom wall of the feeding chute, the axial direction of the feeding roller 2370 is parallel to the width direction of the feeding chute, the feeding roller 2370 is used for bearing the workpiece 1110, and the feeding roller 2370 and the workpiece 1110 are in line contact, so that the contact area between the workpiece 1110 and the bottom wall of the feeding chute is reduced, and the moving resistance is reduced. When the pushing element 2320 pushes the workpiece 1110 to move in the feeding slot, the feeding roller 2370 is also driven to rotate clockwise around the axis thereof, so that the workpiece 1110 can move to the receiving position quickly.

As shown in fig. 8, in a specific embodiment, the pushing driving assembly includes a first rack 2341, a first gear 2340 and a driving member 2330, the first rack 2341 is mounted on the feeding member 2310, the first rack 2341 is parallel to the feeding slot, and the first gear 2340 is in meshing transmission with the first rack 2341; the driving member 2330 is connected with the first gear 2340, the driving member 2330 drives the first gear 2340 to rotate around the axis of the first gear 2340, the position of the first rack 2341 is fixed, so that the first gear 2340 and the driving member 2330 move along the length direction of the first rack 2341, the first gear 2340 is connected with the pushing member 2320, and the pushing member 2320 is driven to move in the feeding slot, so that the workpiece 1110 is pushed.

As shown in fig. 8, in an embodiment, the pushing mechanism further includes a limiting component 2380, and the limiting component 2380 is disposed at an end of the feeding chute away from the blanking mechanism; the spacing assembly 2380 includes a first resilient member and a sensor coupled to the first resilient member. When the workpiece is conveyed to the right end of the feeding groove, the first elastic piece can be extruded, and after the first elastic piece is extruded, the inductor can sense the first elastic piece, so that the first elastic piece is fed back to the material pushing driving assembly, the material pushing driving assembly stops acting, and the workpiece 1110 is prevented from being flushed out of the feeding groove.

As shown in fig. 7 and 8, the blanking sorter 140 further includes a sorting mechanism including a flipping drive 2420 and a first frame 2430 spaced from the V-groove, the first frame 2430 being configured to collect workpieces 1110 within a first length range, such as short workpieces 1110 having a length dimension of 40mm-60 mm. The feeding member 2310 is in a V shape, and the feeding member 2310 includes a plurality of sections, such as M sections and N sections shown in fig. 8, along the length direction thereof. When the size of the cut target workpiece 1110 belongs to the interval, the pushing element 2320 pushes the workpiece 1110 to the M sections of the feeding element 2310, the M sections of the feeding element are connected with the turning driving element 2420, and the M sections of the feeding element 2310 can be turned downwards relative to the N sections of the feeding element 2310. The section M of the feeding member 2310 is driven to be turned downwards by the turning driving member 2420, so that the opening of the V-shaped groove is rotated to face the first material frame 2430. The work piece 1110 pushed thereto falls into the first material frame 2430 through the opening, thereby collecting the short work piece 1110. In other embodiments, only the side wall (i.e. one side of the V-shape) of the feeding member M section may be turned downward, and after the side wall of the feeding member M section is driven by the turning driving member to turn over for a certain angle, the workpiece falls into the first material frame along the side wall.

When the length of the cut workpiece 1110 belongs to the interval, the pushing element 2320 pushes the workpiece 1110 to N sections of the feeding element shown in fig. 8, so that the workpiece 1110 is located below the robot 310, and the robot 310 can move downward to take the workpiece. As shown in fig. 10, the robot 310 includes a mounting plate 3140, a vacuum generator 3160, and a plurality of suction cups, wherein the suction cups and the vacuum generator 3160 are disposed on the mounting plate 3140, and the suction cups are connected to the vacuum generator 3160. The vacuum generator 3160 initiates a suction of negative air pressure, causing the suction cup to generate a vacuum suction force, thereby sucking the workpiece 1110. The robot 310 further includes a transfer member 3110, the transfer member 3110 is connected to the mounting plate 3140, and the transfer member 3110 is configured to drive the mounting plate 3140 to move, so as to transfer the workpiece 1110 sucked by the suction cup to the second material frame 3230, thereby achieving the collection of the long workpiece 1110. Specifically, the transfer device 3110 is a six-axis robot, and thus can drive the adsorbed workpiece 1110 to move above the second frame 3230. The suction cups include circular suction cup 3120 and elliptical suction cup 3130. Wherein, circular sucking disc 3120 is used for absorbing the cross section for work piece 1110 that the surface is curved surface form such as circular or ellipse, and oval sucking disc 3130 is used for absorbing the square work piece 1110 that the surface is planar, and the stability of snatching of work piece 1110 is guaranteed through setting up the absorption of the sucking disc adaptation different shapes work piece 1110 of different grade type.

With continued reference to fig. 10, in an alternative embodiment, the robot 310 further includes a second elastic member 3150, and the second elastic member 3150 is connected between the suction cup and the mounting plate 3140. When the suction cup is sucking workpieces 1110 of different sizes, there is a certain degree of elastic deformation. For example, when adsorbing a circular tube with a large radial dimension, the workpiece 1110 located below the suction cup can squeeze the second elastic member 3150, so that the suction cup has a certain buffer space, and the risk that the workpiece 1110 crushes the suction cup due to large pressure is reduced. The second elastic member 3150 may be a spring.

The workpieces 1110 with different length and size are collected through the first material frame 2430 and the second material frame 3230 respectively, so that the workpieces 1110 are conveyed to the material frames at corresponding positions according to the size of the workpieces 1110, classification of the workpieces 1110 is achieved, all the workpieces 1110 do not need to be stacked together for manual classification, and labor cost is reduced.

As shown in fig. 5 and 11, in an embodiment, the unloading and sorting apparatus 140 further includes a track 3220 and a material transporting vehicle 3240 slidably disposed on the track 3220, wherein the track 3220 is buried on the ground and is located below the manipulator 310.

As shown in fig. 7, a full load sensor 3210 is disposed on one side of the second frame 3230, and is configured to detect loading of the workpieces 1110 in the second frame 3230. When the workpieces 1110 are fully stacked in the second material frame 3230, the full-load sensor senses the full load and feeds the full-load to the material transporting vehicle 3240, and the material transporting vehicle automatically moves to a set position along the track 3220 to obliquely move the second material frame 3230 fully filled with the workpieces 1110 downward, and then the empty second material frame 3230 is loaded for frame replacement. Specifically, a plurality of positioning pins 3250 are arranged on the material transporting vehicle 3240, and the positioning pins 3250 are matched with positioning holes on the second material frame 3230, so that a worker can conveniently and quickly lift or fork the second material frame 3230 onto the material transporting vehicle 3240.

Furthermore, two material conveying vehicles 3240 are arranged on one side of the feeding groove, so that when one material conveying vehicle 3240 changes material frames, the robot can stack the workpieces 1110 into the second material frame 3230 of the other material conveying vehicle 3240, collection operation is not required to be performed after the empty second material frame 3230 is changed, and stacking efficiency is kept.

When the pusher 2320 approaches the marking mechanism 250, the marking driver 2520 drives the marker 2550 to ascend and retreat, preventing interference of the mechanism. Specifically, the marking driving member 2520 includes a servo motor, a second gear 2540 and a second rack 2530 in meshing transmission with the second gear 2540, and when the workpiece 1110 passes under the marker 2550, the servo motor drives the second gear 2540 to rotate, and controls the marker 2550 connected with the second rack 2530 to move downwards in a direction close to the workpiece 1110, so as to mark the surface of the workpiece 1110.
