Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of part size detection, and particularly relates to a part size detection device with intelligent positioning function. BACKGROUND

[0002] With the continuous development and progress of the machining industry, people's requirements for product structure and product surface are increasingly precise, and various parts need to be used for assembly and fixation in the product assembly process. In the production process of micro tubular parts, size and defect detection of the produced micro tubular parts are needed in order to control precision.

[0003] In the process of detecting micro tubular parts, in order to improve efficiency, the micro tubular parts are usually transported and arranged on the guide rail by using the vibration disc and the linear array device. After passing through the guide rail, the parts will be placed on the turntable in a transverse direction, and then the parts will be continuously transported by the rotation of the turntable to pass through the high-speed detection camera for size and defect detection analysis. However, when the micro tubular parts are arranged and transported by the vibration disc and the linear array device to the guide rail, due to the difference in the time of transportation and arrangement, the distance between each group of parts and the adjacent parts before and after is prone to have a gap, and even two groups of parts may be close together, so that the parts on the turntable are also in a close state. When the parts pass through the high-speed detection camera for detection, the close or close state is prone to cause detection errors. In addition, in order to facilitate the collection of the parts after detection, the annular accommodating groove on the turntable is not convenient to be too deep, which will cause the risk of being thrown out by centrifugal force when the rotation speed of the turntable is high, thereby limiting the detection efficiency.

DETAILED DESCRIPTION

[0029] Clearly, the embodiments described are only a part of the embodiments of the present application, rather than all the embodiments.

The vibrating disc 11 is installed on the workbench 1. The guide rail 12 is fixedly connected with the vibrating disc 11. The linear array device 13 is fixedly connected between the guide rail 12 and the workbench 1. The rotating disc 14 is rotationally connected with the workbench 1. The containing groove 141 is arranged on the rotating disc 14. The guide rail 12 extends to the edge of the rotating disc 14. The detection camera 15 is fixedly connected on the workbench 1.

The adjusting assembly 3 is arranged in the positioning assembly 2 and rotationally connected with the positioning assembly 2. The protection assembly 4 is arranged near the edge of the rotating disc 14. The collecting assembly 5 is installed on the workbench 1. In the working process, the vibrating disc 11 and the linear array device 13 can arrange tubular parts on the guide rail 12. Then, the tubular parts will be continuously conveyed to the containing groove 141 along with the rotation of the rotating disc 14. When the tubular parts leave the guide rail 12, they will first pass through the positioning assembly 2. The equidistant distribution of the tubular parts on the rotating disc 14 can be realized through the positioning arrangement of the positioning assembly 2. Then, the equidistantly distributed tubular parts will pass through the detection camera 15 and the collecting assembly 5 in turn along with the rotation of the rotating disc 14. The detection camera 15 can identify and analyze unqualified parts. Then, the collecting assembly 5 can classify and collect the qualified parts and the unqualified parts. In the process of the rotation of the rotating disc 14, the protection assembly 4 can play a reinforcing role on the tubular parts, so as to prevent the parts from being thrown out of the rotating disc 14 due to centrifugal force in the case that the rotating speed of the rotating disc 14 is relatively high.

[0032] Referring to Figures 4 to 6The positioning assembly 2 comprises a support frame 21, arc-shaped guide plates 22, a baffle 23, clamping blocks 24, elastic members 25, support blocks 26, a sliding frame 27, elastic members 28, a protruding block 29, a motor 210, a roller 211 and a pushing block 212. The support frame 21 is fixedly connected with the workbench 1. The arc-shaped guide plates 22 are fixedly connected with the support frame 21. There are two groups of arc-shaped guide plates 22, and a channel is formed between the two groups of arc-shaped guide plates 22. The curvature of the accommodating groove 141 is consistent with the curvature of the channel formed between the two groups of arc-shaped guide plates 22. The baffle 23 is fixedly connected between the two groups of arc-shaped guide plates 22. There are two groups of clamping blocks 24, and the clamping blocks 24 are respectively and slidably connected with the two groups of arc-shaped guide plates 22. The outer side of the clamping block 24 is provided in a slope. The elastic members 25 are fixedly connected between the two groups of clamping blocks 24. The support blocks 26 are fixedly connected above the arc-shaped guide plates 22. The sliding frame 27 is slidably connected with a fixed block. The elastic members 28 are fixedly connected between the fixed block and the sliding frame 27. The protruding block 29 is fixedly connected at the middle position of the top surface of the sliding frame 27. The motor 210 is fixedly connected above the arc-shaped guide plates 22. The roller 211 is fixedly connected with the output shaft of the motor 210. The pushing block 212 is provided with a plurality of groups of circumferential arrays outside the roller 211. One side of the pushing block 212 is provided in a slope.When the detection work starts, when the motor 210 rotates clockwise, the roller 211 will drive the push block 212 to rotate, when the push block 212 continuously passes the protrusion 29, the sliding frame 27 will be continuously pushed to overcome the elastic force of the elastic element two 28 to move up and down along the support block 26, when the sliding frame 27 moves down, the sliding frame 27 on both sides will abut against the inclined surface of the clamping block 24, thereby pushing the two sets of clamping blocks 24 to overcome the elastic force of the elastic element one 25 to approach each other, when the sliding frame 27 rises, the two sets of clamping blocks 24 will move away from each other, when the detection work on the part starts, the first tubular part leaves the guide rail 12 and enters the passage between the arc-shaped guide plates 22, which will be transferred to the right side of the arc-shaped guide plates 22 along with the rotation of the turntable 14, at this time the motor 210 will start to drive the roller 211 to rotate the push block 212, thereby driving the protrusion 29 and the sliding frame 27 to descend, thereby causing the clamping blocks 24 to approach each other to clamp the part between the clamping blocks 24, then the motor 210 will be paused, at this time the tubular part will not be able to pass through, therefore the tubular parts continuously conveyed between the arc-shaped guide plates 22 will be arranged in the passage between the arc-shaped guide plates 22 with the movement of the turntable 14, when the tubular parts are arranged in the entire passage, the motor 210 can be started to continue to work to drive the turntable 14 to rotate at a constant speed, causing the clamping blocks 24 to perform reciprocating closing action, when the clamping blocks 24 are opened, the tubular parts will rotate with the turntable 14, when the clamping blocks 24 approach each other, the tubular parts will be temporarily stopped, thereby the tubular parts passing through the clamping blocks 24 will be distributed at equal distances on the turntable 14, achieving the effect of positioning and distributing the tubular parts on the turntable 14, preventing the state of too close or close between two sets of tubular parts.

[0033] With reference to Figure 5 and Figure 6 , the support frame 21 is fixedly connected to the middle position of the transverse direction of the arc-shaped guide plate 22, the baffle 23 is fixedly connected to the middle position of the longitudinal direction of the arc-shaped guide plate 22, and the slot is formed in the baffle 23; the connection and fixing mode between the support frame 21 and the baffle 23 and the arc-shaped guide plate 22 can improve the stability of the whole work of the adjusting assembly 3, prevent the arc-shaped guide plate 22 from deforming after long-time work, and facilitate observation of the distribution state of the tubular parts below the baffle 23 through the slot in the baffle 23.

[0034] With reference to Figure 5 and Figure 7The adjusting assembly 3 comprises a rotating groove 31, a folding groove 32, a circular plate 33, support rods 34, and push blocks 35. The rotating groove 31 is arranged in the inside of the roller 211, the folding groove 32 is arranged on the push block 212, the rotating groove 31 and the folding groove 32 are connected, the circular plate 33 is rotationally connected with the center of the roller 211, the number of the support rods 34 is consistent with that of the push block 212, the support rods 34 are circumferentially arranged on the outer periphery of the circular plate 33, the push blocks 35 are fixedly connected with the ends of the support rods 34, the push blocks 35 are slidably connected with the folding groove 32, and the outer surface of the push blocks 35 is consistent with the curvature of the outer surface of the push block 212. By rotating the circular plate 33, the support rods 34 and the push blocks 35 are driven to slide along the folding groove 32 on the push block 212. When the circular plate 33 is rotated clockwise, the push blocks 35 are retracted into the folding groove 32 on the push block 212. When the circular plate 33 is rotated counterclockwise, the push blocks 35 are extended out of the folding groove 32, which is equivalent to extending the path of the push block 212, thereby prolonging the time of the push block 212 passing through the convex block 29, and further prolonging the time of the clamping block 24 clamping the tubular parts, thereby increasing the interval distance between the tubular parts. Conversely, by rotating the circular plate 33 clockwise, the push blocks 35 are retracted into the folding groove 32 on the push block 212, which can shorten the interval distance between the tubular parts.

[0035] With reference to Figure 5 and Figure 7 An arc-shaped clamping groove 2111 is further arranged on the roller 211, and a bolt 341 is threadedly connected with the support rod 34. The bolt 341 is threadedly connected with the support rod 34 through the arc-shaped clamping groove 2111. When the position of the push block 212 in the folding groove 32 is adjusted, the bolt 341 can be rotated to fix the support rod 34 on the arc-shaped clamping groove 2111, so as to prevent the push block 212 from rotating alone during the rotation of the roller 211.

[0036] With reference to Figures 8 to 10The protection assembly 4 comprises a ring groove 41, an expansion groove 42, a stopper 43, a pressing block 44, a third elastic element 45, a fixed rod 46 and a pressing wheel 47. The ring groove 41 is arranged near the outer ring of the accommodating groove 141. The expansion groove 42 is arranged near the outer ring of the expansion groove 42 in multiple groups. The stopper 43 is arranged in multiple groups and is in sliding connection with the ring groove 41. The pressing block 44 is in sliding connection with the expansion groove 42. The pressing block 44 is fixedly connected with the stopper 43 through a connecting block. The third elastic element 45 is arranged between the expansion groove 42 and the pressing block 44. The fixed rod 46 is fixedly connected with the workbench 1. The pressing wheel 47 is in rotary connection with the fixed rod 46. During the rotation of the rotating disc 14, the stopper 43 can play a role in blocking and reinforcing the tubular part, so that the tubular part is prevented from being thrown out of the rotating disc 14 due to the centrifugal force of the rotating disc 14. When the pressing block 44 passes through the pressing wheel 47, the pressing wheel 47 will make the pressing block 44 overcome the elastic force of the third elastic element 45 and shrink into the expansion groove 42, and drive the stopper 43 to shrink into the ring groove 41 through the connecting block. At this time, the top surfaces of the stopper 43 and the pressing block 44 are in the same plane as the top surface of the rotating disc 14. After the pressing block 44 passes through the pressing wheel 47, the pressing block 44 will be pushed out by the thrust of the third elastic element 45, and the stopper 43 will be pushed out together, so as to play a role in blocking and reinforcing the tubular part.

[0037] With reference to Figure 9 The distance between the bottom surface of the arc-shaped guide plate 22 and the rotating disc 14 is greater than the maximum distance by which the stopper 43 extends out of the ring groove 41. Therefore, during the rotation of the stopper 43 following the rotating disc 14, the stopper 43 can smoothly pass under the arc-shaped guide plate 22, so that the movement of the stopper 43 is prevented from being interfered by the arc-shaped guide plate 22.

[0038] With reference to Figures 8 to 10 The collection assembly 5 comprises a collection box one 51, a pushing air gun 52, a collection box two 53 and a shifting rod 54. The collection box one 51 and the collection box two 53 are fixedly connected with the workbench 1. The pushing air gun 52 is fixedly connected with the collection box one 51. The shifting rod 54 is fixedly connected with the collection box two 53. The collection box one 51 and the collection box two 53 are both provided with the pressing wheel 47 on both sides of the inlet. After the tubular part is detected by the detection camera 15, the tubular part will be rotated to the collection box one 51. At this time, the pressing block 44 will be pressed by the pressing wheel 47 at the position of the collection box one 51 to drive the stopper 43 to retract into the ring groove 41, so that the tubular part passing through the position of the collection box one 51 will not be blocked by the stopper 43. Then the pushing air gun 52 will start to work to blow the tubular part with defects into the collection box one 51 for collection. When the pressing block 44 passes through the collection box two 53, the pressing block 44 will also be pressed by the pressing wheel 47 at the position of the collection box two 53 to drive the stopper 43 to retract into the ring groove 41. At this time, the qualified tubular part passing through the collection box two 53 will be affected by the shifting rod 54 to enter the collection box two 53 for collection.

[0039] Working principle: in the working process vibration disc 11 and linear array device 13 will arrange the tubular parts to guide rail 12, then with the rotation of the rotating disc 14, tubular parts will be continuously transported to the containing groove 141 on the guide rail 12, when starting to detect the parts, the first tubular part leaves the guide rail 12 into the passage between the arc-shaped guide plate 22, will be transferred to the right side of the arc-shaped guide plate 22 with the rotation of the rotating disc 14, at this time the motor 210 will start to make the roller 211 drive the push block 212 to rotate, and then push the protrusion 29 and the sliding frame 27 to descend, and then make the clamp block 24 overcome the elastic force of the elastic element 25 to approach each other to clamp the parts between the clamp block 24, then the motor 210 will be paused, at this time the state tubular part will not be able to pass through, so the continuously transported tubular parts between the arc-shaped guide plate 22 will be moved with the rotating disc 14, and arranged in the passage between the arc-shaped guide plate 22 in head-to-tail, when the tubular parts are full in the whole passage, the motor 210 can be started to continue to work to drive the rotating disc 14 to keep uniform rotation, so that the clamp block 24 does reciprocating closing action, when the clamp block 24 is open, the tubular parts will rotate with the rotating disc 14, when the clamp block 24 approaches each other, the tubular parts will stop for a while, and then the tubular parts passing through the clamp block 24 will be equally distributed on the rotating disc 14, realizing the effect of positioning and distributing the tubular parts on the rotating disc 14, preventing the state that two groups of tubular parts are too close or close together.

[0040] When the tubular parts pass through the detection camera 15, they will be rotated to the collection box 51, at this time the pressure block 44 will be pressed down by the pressure wheel 47 at the position of the collection box 51 to drive the stop block 43 to retract into the ring groove 41, so that the tubular parts passing through the position of the collection box 51 will not be blocked by the stop block 43, then the pushing air gun 52 will start to work to blow the defective tubular parts into the collection box 51 for collection, when the pressure block 44 passes through the collection box 53, the pressure block 44 will also be pressed down by the pressure wheel 47 at the position of the collection box 53 to drive the stop block 43 to retract into the ring groove 41, at this time the qualified tubular parts passing through the collection box 53 will be affected by the push rod 54 to enter the collection box 53 along the push rod 54 for collection.

[0041] And by rotating the circular plate 33, it will drive the support rod 34 and the push block 35 to slide along the closing groove 32 on the push block 212, when rotating the circular plate 33 clockwise, the push block 35 will retract into the closing groove 32 on the push block 212, when rotating the circular plate 33 counterclockwise, the push block 35 will extend out of the closing groove 32, which is equivalent to extending the path of the push block 212, and then extending the time of the push block 212 passing through the protrusion 29, and then increasing the time of the clamp block 24 clamping the tubular parts, and then increasing the interval distance between the tubular parts, on the contrary, by rotating the circular plate 33 clockwise, the push block 35 retracts into the closing groove 32 on the push block 212, which can shorten the interval distance between the tubular parts.
