Referring to fig. 1, 2 and 3, a material receiving device 10 according to an embodiment of the present invention is used for collecting bad workpieces, which may be cylindrical round pipes, on a production line. The material collecting device 10 includes a material collecting box 100, a base plate 200, a vertical driving mechanism 300, a carrier 400, a horizontal driving mechanism 500, and a base 600.

Referring to fig. 2, 3 and 7, in some embodiments, the material receiving box 100 is used for receiving a workpiece, the material receiving box 100 may be made of a metal material or a non-metal material, and the material receiving box 100 may have a substantially flat rectangular structure. The material receiving box 100 comprises a bottom plate 110 and a side frame 120, wherein the side frame 120 encloses a cavity, and the cavity is provided with openings at two ends of the side frame 120. The bottom plate 110 is fixed to one end of the side frame 120 and closes the opening of the cavity at the end, and the opening of the cavity at the other end of the side frame 120 is not closed and is open, so that the bottom plate 110 and the side frame 120 together enclose an open cavity 130. As is apparent, the side frame 120 is disposed around the perimeter of the base plate 110 and the open cavity 130 is generally rectangular in cross-section. The width of the open cavity 130 may be approximately four to five times the diameter of the workpiece, such that four to five workpieces may be placed side by side in the width direction of the open cavity 130. Of course, the width of the open cavity 130 can be increased or decreased appropriately according to the actual requirement, so that two or more than five workpieces can be placed side by side in the open cavity 130. The bottom plate 110 and the side frame 120 may be fixedly connected by separate connection methods such as welding, clamping, screwing, and the like, or the receiving box 100 may be integrally formed by injection or stamping, and the like.

In some embodiments, the bottom plate 110 is provided with an avoiding groove 111, the avoiding groove 111 may be substantially rectangular, the avoiding groove 111 is disposed in the middle of the bottom plate 110, and the center of the avoiding groove 111 may coincide with the center of the bottom plate 110. Since the rectangular bottom plate 110 has an axisymmetrical pattern, and the bottom plate 110 has a symmetry axis extending in the longitudinal direction and a symmetry axis extending in the width direction, the avoiding grooves 111 may be provided symmetrically with respect to the symmetry axis extending in the longitudinal direction of the bottom plate 110, or the avoiding grooves 111 may be provided symmetrically with respect to the symmetry axis extending in the width direction of the bottom plate 110. The avoiding groove 111 penetrates the entire bottom plate 110 along the thickness direction of the bottom plate 110, so that the avoiding groove 111 communicates with the open cavity 130 and the outside at the same time. The length of the avoiding groove 111 is greater than that of the bearing part 400, and meanwhile, the length of the avoiding groove 111 is smaller than that of the workpiece. Through the arrangement, on one hand, the bearing member 400 can pass through the avoiding groove 111, interference of the bottom plate 110 on the movement of the bearing member 400 is avoided, and the bearing member 400 can enter or leave the open cavity 130 from the avoiding groove 111; on the other hand, the workpiece cannot pass through the avoiding groove 111, and the workpiece is prevented from falling out of the receiving box 100 from the avoiding groove 111.

The side frame 120 is provided with a through groove 121, the through groove 121 penetrates the entire side frame 120 along the thickness direction of the side frame 120, so that the through groove 121 is directly communicated with the open cavity 130 and the outside, and meanwhile, the lower end of the through groove 121 extends to the lower end of the side frame 120 and continuously penetrates the entire bottom plate 110 along the thickness direction of the bottom plate 110, so that the through groove 121 is directly communicated with the clearance groove 111 on the bottom plate 110. Of course, a set distance may be maintained between the upper end of the penetration groove 121 and the upper end of the side frame 120. Therefore, the through grooves 121 extend in the vertical direction, and the avoiding grooves 111 extend in the horizontal direction, so that the symmetry axis in the length direction of the avoiding grooves 111 and the symmetry axis in the length direction of the through grooves 121 are perpendicular to each other, and obviously, the symmetry axis in the width direction of the avoiding grooves 111 and the symmetry axis in the width direction of the through grooves 121 are also perpendicular to each other.

The number of the material receiving boxes 100 may be two, and the two material receiving boxes 100 may be arranged at intervals in the width direction thereof. Of course, in other embodiments, the number of the receiving boxes 100 may be increased or decreased as needed according to actual situations, for example, the number of the receiving boxes 100 may be one, or the number of the receiving boxes 100 may be an even number greater than two, or the number of the receiving boxes 100 may also be an odd number greater than one.

Referring to fig. 3, 4 and 5, in some embodiments, the substrate 200 may have a substantially rectangular plate-like structure. The vertical driving mechanism 300 includes a top plate 310, a guide lever 320, a sliding block 330, a lead screw 340, and a driver 350. The top plate 310 and the base plate 200 are spaced apart in the vertical direction, the top plate 310 is located above the base plate 200, and the top plate 310 is located in the space between the two material receiving boxes 100. The number of the guide bars 320 may be two, the guide bars 320 may be substantially cylindrical, and the guide bars 320 are spaced apart along the length of the receiving box 100. One end (lower end) of the guide rod 320 is fixed on the base plate 200, the other end (upper end) of the guide rod 320 is fixed on the top plate 310, and the position of the top plate 310 relative to the base plate 200 is always kept constant through the limiting function of the guide rod 320, namely the top plate 310 cannot rotate or slide relative to the base plate 200. In this embodiment, the driver 350 is a rotating motor, and the driver 350 is fixed on the substrate 200. The upper end of the screw 340 is rotatably connected with the top plate 310, the lower end of the screw 340 is fixedly connected with an output shaft of the driver 350, and the driver 350 can drive the screw 340 to rotate relative to the top plate 310 through the output shaft.

The sliding block 330 is located between the top plate 310 and the base plate 200, the middle part of the sliding block 330 is screwed on the screw 340, one end (left end) in the length direction of the sliding block 330 is slidably sleeved on one of the guide rods 320, and the other end (right end) in the length direction of the sliding block 330 is slidably sleeved on the other guide rod 320. Through setting up the guide bar 320, can improve the slip precision and the stability of sliding block 330, avoid the skew slip orbit of setting for of sliding block 330, also can prevent that sliding block 330 from producing at the slip in-process and rocking or jamming the phenomenon. Of course, a bearing can be further installed in the sliding block 330, the bearing is directly sleeved on the guide rod 320 in a sliding manner, and a certain amount of lubricating oil can be further added into the bearing, so that the frictional resistance generated in the sliding process of the sliding block 330 relative to the guide rod 320 can be greatly reduced, and therefore, on one hand, the sensitivity of the sliding block 330 to the response of the driving force can be improved, on the other hand, the abrasion of the guide rod 320 generated under the action of the frictional resistance can be reduced, the service life of the guide rod 320 is ensured, and the sliding precision and the stability of the sliding block 330 are further improved. The two ends of the sliding block 330 in the width direction respectively pass through the through slots 121 of the side frames 120 and extend into the open cavity 130, so that the sliding block 330 is inserted into the through slots 121.

Referring to fig. 3, 4 and 5, in some embodiments, the carrier 400 is received in the open cavity 130 of the material receiving box 100, and the carrier 400 is used for carrying the workpiece in the open cavity 130. The number of the carriers 400 is two, and the two carriers 400 and the two material receiving boxes 100 form a one-to-one correspondence relationship. One of the bearing members 400 is fixedly connected with one end (front end) of the sliding block 330 in the width direction, and the other bearing member 400 is fixedly connected with the other end (rear end) of the sliding block 330 in the width direction, so that the bearing members 400 are all accommodated in the open cavity 130 of the material receiving box 100. The supporting member 400 has a substantially rectangular plate-shaped structure, the supporting member 400 may be made of a metal material or a non-metal material, for example, the supporting member 400 may have a certain flexibility, and when the first workpiece falls onto the supporting member 400 and directly contacts the supporting member 400, the supporting member 400 may absorb the impact force generated during the collision between the workpiece and the supporting member 400 due to the certain flexibility of the supporting member 400, so as to avoid the damage of the workpiece under the impact force, and improve the possibility that the workpiece becomes a good product through subsequent trimming.

When the vertical driving mechanism 300 is operated, for example, the output shaft of the driver 350 rotates clockwise, which can drive the lead screw 340 to rotate clockwise, so that the lead screw 340 drives the sliding block 330 to slide along the guiding rod 320 downwards to approach the base plate 200, and finally the bearing member 400 follows the sliding block 330 to slide downwards in the open cavity 130. The counterclockwise rotation of the output shaft of the driver 350 can drive the lead screw 340 to rotate counterclockwise, so that the lead screw 340 drives the sliding block 330 to slide along the guiding rod 320 upward and close to the top plate 310, and finally the bearing member 400 slides upward in the open cavity 130 along with the sliding block 330. Through the through groove 121 formed in the side frame 120, the interference of the side frame 120 on the sliding block 330 during the up-and-down sliding process of the sliding block 330 can be effectively eliminated, and the sliding block 330 can smoothly drive the bearing member 400 to slide up and down in the open cavity 130.

In some embodiments, a space is present between the periphery of the carrier 400 and the side frame 120, so as to avoid direct contact between the carrier 400 and the side frame 120. Therefore, when the supporting member 400 slides up and down in the open cavity 130, the friction force between the supporting member 400 and the side frame 120 due to the contact with the side frame 120 can be prevented, so that the sliding resistance of the supporting member 400 moving up and down in the open cavity 130 can be greatly reduced, the clamping stagnation or shaking caused by the excessive resistance of the supporting member 400 in the sliding process can be avoided, and the large abrasion of the supporting member 400 and the side frame 120 under the excessive friction force can be effectively avoided. The supporting member 400 is recessed to form a limiting groove 410, the shape of the limiting groove 410 is adapted to the shape of the workpiece, and the width of the limiting groove 410 gradually decreases along the direction from top to bottom, for example, the limiting groove 410 may be a V-shaped groove. The workpiece directly contacting the carrier 400 can be received in the stopper groove 410, and the workpiece is prevented from rolling on the carrier 400 and falling off the carrier 400, thereby effectively performing a function of the carrier 400 for supporting the workpiece. The number of the limiting grooves 410 may be one, and certainly, the number of the limiting grooves 410 may also be two or more than three, and the like, and when the number of the limiting grooves 410 is plural, the plural limiting grooves 410 are arranged at intervals in the width direction of the carrier 400. In the case where the number of the retaining grooves 410 is plural, it is ensured that the number of the workpieces directly contacting the carrier 400 is equal to the number of the retaining grooves 410.

In other embodiments, the sliding block 330 may be driven by an air cylinder or a linear motor, in addition to the lead screw 340, that is, by fixedly connecting an output shaft of the air cylinder or the linear motor with the sliding block 330. When the output shaft driven by the cylinder or the linear motor generates the telescopic motion in the vertical direction, the sliding block 330 can also be driven to reciprocate up and down in the vertical direction along the guide rod 320, and finally the bearing member 400 slides down in the open cavity 130 along with the sliding block 330.

Referring to fig. 3, 4 and 5, in some embodiments, the horizontal driving mechanism 500 includes a cylinder 510 and a guide shaft 520, the base 600 is slidably sleeved on the guide shaft 520, the guide shaft 520 may be a cylindrical rod-shaped structure, the guide shaft 520 extends along a horizontal direction, and since the guide rod 320 extends along a vertical direction, the extending direction of the guide shaft 520 and the extending direction of the guide rod 320 are perpendicular to each other, such that the sliding direction of the base 600 relative to the guide shaft 520 is perpendicular to the sliding direction of the carrier 400 relative to the material receiving box 100. The cylinder barrel of the cylinder 510 is fixed on the base plate 200, and the piston rod of the cylinder 510 is fixedly connected with the base 600. When the piston rod of the cylinder 510 generates a telescopic motion, the base 600 can be driven to slide back and forth along the guide shaft 520 in the horizontal direction. Through setting up guiding axle 520, can improve the slip precision and the stability of base 600, avoid base 600 skew to set for the slip orbit, also can prevent that base 600 from rocking or jamming phenomenon producing at the slip in-process. Of course, a bearing can be further installed in the base 600, the bearing is directly sleeved on the guide shaft 520 in a sliding manner, and certain lubricating oil can be further added into the bearing, so that the frictional resistance generated in the sliding process of the base 600 relative to the guide shaft 520 can be greatly reduced, the sensitivity of the base 600 to the response of the driving force can be improved, the abrasion of the guide shaft 520 under the action of the frictional resistance can be reduced, the service life of the guide shaft 520 is ensured, and the sliding precision and the stability of the base 600 are further improved.

Referring to fig. 4, 5 and 6, the base 600 is provided with an accommodating cavity 610 and a sliding groove 620, a portion of the material receiving box 100 near the lower end is accommodated in the accommodating cavity 610, and other portions of the material receiving box 100 are exposed outside the accommodating cavity 610. The base 600 can be directly inserted into the receiving cavity 610, so that the receiving box 100 and the base 600 can be detachably connected. The base 600 further has a sliding groove 620, the sliding groove 620 extends along the horizontal direction, the sliding groove 620 is communicated with the accommodating cavity 610, and when the material receiving box 100 is inserted into the accommodating cavity 610, the sliding groove 620 is also communicated with the position avoiding groove 111 on the material receiving box 100. The two ends of the sliding groove 620 in the length direction are not closed, that is, end openings 621 communicated with the outside are arranged at the two ends of the sliding groove 620 in the length direction. When the carrier 400 vertically enters the sliding slot 620 from the open cavity 130 through the clearance slot 111 and the base 600 slides relative to the guide shaft 520, the carrier 400 can be made to enter or leave the sliding slot 620 from the end opening 621.

When the material receiving device 10 works, in the first step, the driver 350 drives the sliding block 330 to move upward through the screw 340, so that the bearing member 400 moves to a position close to the upper end opening 131 of the open cavity 130 along with the sliding block 330, and the bearing member 400 is still located in the open cavity 130, for example, the distance between the upper surface of the bearing member 400 and the upper end opening 131 of the open cavity 130 can be approximately equal to the diameter of the workpiece.

Secondly, the bad workpiece is moved to a designated position above the open cavity 130 by the manipulator, and then the manipulator is loosened, so that the workpiece falls into the limiting groove 410 of the bearing part 400, and meanwhile, the open cavity 130 plays a role in accommodating the workpiece.

Third, when the workpiece is received in each of the retaining grooves 410 of the carrier 400 (hereinafter, two retaining grooves 410 are used for explanation), the two workpieces are substantially flush with the upper opening 131 of the open cavity 130. To prevent the next (i.e., the third) workpiece falling onto the carrier 400 from sliding away from the open cavity 130, the next workpiece is ensured to be received in the open cavity 130, and at this time, the driver 350 drives the sliding block 330 to move downward through the lead screw 340, so that the carrier 400 slides downward along with the sliding block 330 by a set distance, which may be substantially equal to the diameter of the workpiece. Thus, when a third workpiece is dropped, it can just be received in the open cavity 130, and of course, the third workpiece may not be in direct contact with the carrier 400. And then drop a fourth workpiece onto the carrier 400.

Fourth, considering that four workpieces have been loaded on the carrier 400, the two workpieces on the top level have been flush with the upper end opening 131 of the open cavity 130, and then the carrier 400 is driven to slide downward by a distance substantially equal to the diameter of the workpieces, and then two workpieces continue to drop onto the carrier 400. At this point, six workpieces have been carried on the carrier 400, the two workpieces at the top level having been flush with the upper end opening 131 of the open cavity 130, and the carrier 400 is then driven to slide downwardly a distance substantially equal to the diameter of the workpieces. And so on, i.e., each time two workpieces drop onto the carrier 400, the carrier 400 slides downward a set distance, which is approximately equal to the diameter of the workpiece. If the carrier 400 is not provided, when the workpiece is dropped from the robot directly onto the bottom plate 110 of the receiving box, the workpiece is strongly collided with the bottom plate 110 due to the large dropping height of the workpiece, so that the workpiece is damaged, and the workpiece cannot be reused by subsequent trimming. Even if the drop height of the subsequent workpieces is gradually reduced after a certain number of workpieces are accommodated in the open cavity 130, the workpieces with larger drop heights can still be damaged. In the receiving device 10 of the above embodiment, by providing the bearing member 400, after a set number of workpieces periodically drop into the bearing member 400, the bearing member 400 slides for a set distance, on one hand, it can be ensured that the workpieces subsequently dropped onto the bearing member 400 can be accommodated in the open cavity 130, and on the other hand, more importantly, the subsequent workpieces can all move within a set height range and drop into the open cavity 130, in other words, the dropping heights experienced by the workpieces dropping from the manipulator to the open cavity 130 are all approximately equal, and of course, the dropping height is relatively small, so that the workpieces can be effectively prevented from generating a large impact force due to a large dropping height, the workpieces are prevented from being damaged by the impact force, and the workpieces can be ensured to form a recyclable good product through subsequent trimming.

In the fifth step, when the workpiece contained in the open cavity 130 of the receiving box reaches saturation, the carrier 400 has moved into the clearance groove 111 of the bottom plate 110. Then, the carrier 400 is driven to descend continuously, so that the carrier 400 moves from the avoiding groove 111 to the sliding groove 620 of the base 600, that is, the carrier 400 completely detaches from the material receiving box 100 and enters the base 600.

Sixthly, the cylinder 510 is activated to drive the base 600 to move along the guide shaft 520, and during the process that the base 600 moves along the guide shaft 520, the position of the carrier 400 in the horizontal direction remains unchanged, and the carrier 400 will move relatively in the chute 620, so that the carrier 400 cannot interfere with the movement of both the material receiving box 100 and the base 600 along the guide shaft 520. After the material receiving box 100 moves along the guide shaft 520 for a certain distance along with the base 600, the material receiving box 100 keeps a certain distance from a manipulator for dropping a workpiece into the material receiving box 100 at the initial position, so that the orthographic projection of the manipulator in the vertical direction falls outside the position of the material receiving box 100 at the moment.

And seventhly, the material receiving box 100 is lifted upwards, and interference of a manipulator to the material receiving box 100 can be eliminated in the process of lifting the material receiving box 100. When the material receiving box 100 is pulled out from the containing cavity 610 of the base 600 and completely separated from the base 600, the material receiving box 100 can be inverted, so that the opening of the open cavity 130 is arranged downwards, and at the moment, the workpiece in the open cavity 130 is separated from the material receiving box 100 from the opening and is contained to a specified position. When all the workpieces in the open cavity 130 are taken out, the material receiving box 100 is placed in the base 600 again, the base 600 drives the material receiving box 100 to move for a certain distance along the guide shaft 520 close to the screw rod 340, then the bearing part 400 is driven to upwards enter the open cavity 130 from the sliding groove 620 through the avoiding groove 111, and the bearing part 400 is continuously driven to continuously move upwards in the open cavity 130 to the position where the bearing part 400 is located in the first step, so that the material receiving box 100 opens a new round of work for receiving the workpieces.

Therefore, by arranging the material receiving device 10, the work efficiency can be improved on the basis of avoiding the damage of the workpiece.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
