[0023] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-7 As shown, a steel ball screw conveyor includes a temporary storage section 1, which is fixedly installed on a support frame. Steel balls can be placed in the temporary storage section 1. A lifting section 3 is provided on the side of the temporary storage section 1, and the steel balls in the temporary storage section 1 can be lifted by the lifting section 3, thereby facilitating the transfer of steel balls in the temporary storage section 1. A guide section 2 is provided between the temporary storage section 1 and the lifting section 3 to guide the steel balls in the temporary storage section 1. The steel balls in the temporary storage section 1 can flow naturally and orderly through the guide section 2 to the lifting section 3 under the influence of gravity, thereby facilitating the subsequent lifting of the steel balls. A discharge section 5 is provided on the lifting section 3, and the lifted steel balls can enter the discharge section 5. The discharge section 5 is connected to the next process, so that the steel balls can enter the next process through the discharge section 5 for subsequent processing.

[0025] like Figure 1-6As shown, the temporary storage unit 1 includes a storage box 11 fixed on a support frame. The storage box 11 is an irregular cube with an opening at the top. A lid 12 is hinged to the top of the storage box 11 to close the opening. An electric push rod 13 is hinged to the side of the storage box 11, and the telescopic end of the electric push rod 13 is hinged to the lid 12. The electric push rod 13 is electrically connected to a controller. A through groove 14 is provided on the side of the storage box 11 near the lifting unit 3. The through groove 14 is located at the corner of the storage box 11. When the steel ball is inside the storage box 11, the steel ball can be discharged through the through groove 14 under the action of gravity. A barcode paper is pasted on the surface of the storage box 11. After the worker scans the barcode with a barcode scanner, the signal is transmitted to the controller. Then the controller controls the electric push rod 13 to start, and the electric push rod 13 can push the lid 12 to open. At this time, the steel ball can be easily put into the inside of the storage box 11.

[0026] like Figure 7 As shown, a partition 15 is fixedly connected inside the storage box 11. The partition 15 is inclined to prevent the steel ball from falling directly onto the bottom surface of the storage box 11 when it is poured into the storage box 11, thus avoiding damage to the steel ball.

[0027] like Figure 1 As shown, the flow guide 2 includes a first baffle 21 fixedly connected to the left side of the storage box 11. A flow guide plate 23 is fixedly connected to the bottom end of the first baffle 21. The flow guide plate 23 is inclined, and the steel ball can roll along the flow guide plate 23 toward the lifting part 3. A second baffle 22 is fixedly connected to the flow guide plate 23. After the steel ball is discharged through the through groove 14, it can fall onto the flow guide plate 23 and roll along the flow guide plate 23, thereby conveniently guiding the steel ball to the lifting part 3 for subsequent lifting.

[0028] like Figure 6 As shown, the lifting part 3 includes a housing 31 fixedly connected to the support frame. A spiral rod 32 is rotatably connected inside the housing 31. Two baffles 33 are provided on the side of the spiral rod 32 near the guide plate 23. The baffles 33 are located on the left and right sides of the guide plate 23 and are used to limit the steel balls. The distance between the two baffles 33 can be adjusted, so that steel balls of different diameters can enter the spiral rod 32 through the space between the two baffles 33. After the steel balls enter the spiral rod 32, they are limited and stuck inside the spiral rod 32. A rotary drive component 34 is fixedly connected to the bottom end of the outer casing 31 between the two stop bars 33, and the output end of the rotary drive component 34 is fixedly connected to the bottom end of the screw rod 32. The rotary drive component 34 is a geared motor. The steel ball can roll along the guide plate 23 into the screw rod 32 and be located between the two stop bars 33. Then the rotary drive component 34 is started, and the rotary drive component 34 drives the screw rod 32 to rotate. The rotation of the screw rod 32 can drive the steel ball to move upward, thereby making it easy to lift the steel ball.

[0029] like Figure 1-5 As shown, the outer casing 31 is provided with an adjustment part 4 for adjusting the distance between the two stop rods 33, so that steel balls of different diameters can enter the spiral rod 32, thereby lifting steel balls of different diameters. The adjusting unit 4 includes two fixed plates 41 fixedly connected to the outer casing 31. A movable plate 42 is slidably connected to each of the two fixed plates 41. A locking block 43 is fixedly connected to each of the two movable plates 42. The distance between the two locking blocks 43 is the same as the distance between the two stop rods 33. The two locking blocks 43 are respectively fixedly connected to the two stop rods 33 via two connecting plates 44. A bidirectional lead screw 45 is rotatably connected between the two fixed plates 41, and the bidirectional lead screw 45 is threadedly connected to the movable plate 42. A handle 46 is fixedly connected to one end of the bidirectional lead screw 45. The operator rotates the handle 46 to rotate the bidirectional lead screw 45. Then, the rotation of the bidirectional lead screw 45 drives the two moving plates 42 to move towards each other. The movement of the two moving plates 42 towards each other can drive the locking blocks 43 to move. The operator places a steel ball to be lifted between the two locking blocks 43, so that the two locking blocks 43 are in contact with the steel ball. Thus, the distance between the two locking blocks 43 can be adjusted according to the diameter of the steel ball. Then, the movement of the locking blocks 43 can drive the stop rod 33 to move through the connecting plate 44. Thus, the distance between the two stop rods 33 can be easily adjusted according to the diameter of the steel ball to be lifted, so that steel balls of different diameters can be lifted easily.

[0030] like Figure 2 As shown, the discharge section 5 includes a discharge pipe 51 disposed on the screw rod 32, and the discharge pipe 51 and the steel ball inside the screw rod 32 have an overlapping position. When the steel ball is lifted upward, it can enter the interior of the discharge pipe 51. A tooling fixture 52 is detachably connected to the fixing plate 41. The tooling fixture 52 is used to clamp and fix the discharge pipe 51. The tooling fixture 52 can be a quick-release clamp such as a quick-release pin clamp to fix the discharge pipe 51. After the steel ball enters the housing 31 through the bottom end of the discharge pipe 51, it can be discharged through the top end of the discharge pipe 51 under the pushing of the subsequent steel ball, which makes it easier to carry out the next processing step.

[0031] like Figure 4 As shown, a hollow groove is provided inside the guide plate 23, and a waste trough 6 is fixedly connected to the lower part of the guide plate 23. The waste trough 6 is inclined and located below the hollow groove. When the steel ball in the storage box 11 falls onto the guide plate 23, the impurities mixed in the steel ball can fall onto the waste trough 6 through the hollow groove and slide down along the waste trough 6, thereby removing the impurities mixed in the steel ball.

[0032] Working principle: First, the staff scans the code to open the box cover 12, then places the steel ball in the storage box 11. Then, under the action of gravity, the steel ball slides down from the through groove 14 onto the guide plate 23. The steel ball continues to roll along the guide plate 23. Then, the adjustment part 4 adjusts the distance between the two baffles 33 according to the diameter of the steel ball, and the steel ball can roll through the baffles 33 into the spiral rod 32. Then, the rotation drive 34 drives the spiral rod 32 to rotate. When the spiral rod 32 rotates, the steel ball can be lifted upward and moved into the discharge pipe 51, thus making it easy to lift the steel ball and can lift steel balls of different diameters, improving the applicability of the device.
