Description

Technical Field

[0001] The present invention relates to the technical field of sorting, and particularly relates to an inductive sensor sorting platform. Background Art

[0002] The sorting device is a key link in the production process. By using sensor devices to comprehensively detect the exteriors of various products, it separates qualified products from defective products, prevents defective products from entering the market, reduces human errors, lowers enterprise costs, and improves the operating efficiency and production capacity of the production line.

[0003] However, in the prior art, when detecting small and medium-sized industrial special-shaped die accessories at present, since they are used to manufacture products with specific shapes in industrial production, such as a small motor housing with cavities, positioning grooves or reinforcing ribs, the interior of such workpieces is a flat arc surface, and both sides are flat horizontal surfaces. When two conveying devices are driven by a driving motor to transport the workpiece to the sorting position, a sensing device is used to comprehensively observe the surface. However, a single detector will have omissions, and when scanning comprehensively, it is impossible to observe the local positions of the special-shaped die structure. Therefore, multiple detectors are set to ensure detection and qualified sorting. Thus, a second sensing device is used for local detailed detection for supplementary detection and sorting. However, usually, the second detection position is too fixed, so that the detection always performs detection and sorting on a single position of different workpieces, resulting in the ineffective use of the supplementary sensing device for detection and sorting, reducing the flexibility of detection, and affecting the accuracy and reliability of the detection results.

Detailed implementation manner

[0021] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0022] Refer to Figures 1-8 , which is an embodiment of the present invention, provides an inductive sensor sorting platform for sorting workpieces, including a body 1, and further including a feeder 2 and a material conveyor 3 provided on the top of the body 1, a support frame 4 fixedly connected to the top of the feeder 2, a link 5 connected inside the support frame 4, a connecting sleeve guide rod 6 slidably connected inside the support frame 4, an outer pressing part 7 slidably connected to the link 5, a plurality of spring strips 8 arranged at equal angles and slidably connected inside the bottom end of the link 5, two limiting strips 9 connected inside the support frame 4, a servo motor 10 provided on one side of the support frame 4, a transmission belt 11 sleeved between the servo motor 10 and the link 5, and a telescopic rod 12 and a blocking rod 13 provided on the other side of the support frame 4. One end of the guide rod 6 extends outside the support frame 4 and is located above the telescopic rod 12. The middle part of the guide rod 6 is sleeved outside the link 5. The spring strip 8 is slidably connected to the outer pressing part 7. The servo motor 10 makes the workpiece rotate randomly through the outer pressing part 7 and the spring strip 8.

[0023] Specifically, the feeder 2 and the material conveyor 3 convey workpieces to maintain the coherence and efficiency of the entire inspection and sorting process. The limit bar 9 can restrict the workpieces, enabling the workpieces to remain as close as possible to the center line position of the feeder 2, avoiding position deviation, and ensuring that the workpieces are always in a suitable inspection and sorting position. When the workpiece contacts the blocking rod 13, the telescopic rod 12 contracts, and the guide rod 6 supported by the telescopic rod 12 loses support and moves downward synchronously. Therefore, related components such as the connecting rod 5 connected to the guide rod 6 move downward synchronously. At this time, the bottom end of the downward-moving outer pressure member 7 and the spring strip 8 enter the interior of the workpiece. At the same time, the outer pressure member 7 will fit against the top of the workpiece and be blocked. At this time, the spring strip 8 moving downward with the connecting rod 5 will be affected by the stationary outer pressure member 7 and move towards the position close to the inner wall of the workpiece, causing the inner wall of the workpiece to fit against the spring strip 8. Thus, at this time, multiple spring strips 8 and the outer pressure member 7 are all in contact with the workpiece. Start the servo motor 10 to rotate two weeks, and at the same time, the feeder 2 pauses briefly. When driving the workpiece with multiple spring strips 8 and the outer pressure member 7, the workpiece rotates randomly under the influence of friction, especially in the locally irregular-shaped positions, enabling a secondary randomness assessment, and then sorting is carried out, effectively compensating for the problem of insufficient flexibility in the existing inspection and sorting.

[0024] Referring to Figures 2-6 , the connecting rod 5 includes a rotating rod 51 slidably connected inside the support frame 4, a rotating wheel 52 rotatably connected to the top of the support frame 4, and a weight 53 fixedly connected to the bottom end of the rotating rod 51.

[0025] Referring to Figures 2-6 , the outer pressure member 7 includes a straight bar 71 slidably connected inside the rotating rod 51, a weak spring 72 connected between the straight bar 71 and the rotating rod 51, an inclined block 73 fixedly connected to the bottom end of the straight bar 71, and a plurality of equally spaced groove bars 74 connected to the top of the inclined block 73. The length of the straight bar 71 is greater than the diameter of the weight 53, and the bottom end of the spring strip 8 is slidably connected inside the groove of the groove bar 74.

[0026] The two limit bars 9 are symmetric about the central axis of the support frame 4. The bottom end of the limit bar 9 is rotatably connected inside the circular sleeve weak spring 72. The limit bar 9 includes a pressure rod 91 rotatably connected inside the support frame 4 and a weak torsion spring 92 connected between the pressure rod 91 and the support frame 4.

[0027] Specifically, when the straight bar 71 contacts the surface of the workpiece and is blocked and unable to move, at this time, the rotating rod 51 loses support and is affected by the weight block 53, and moves downward under gravity, causing the weak spring 72 to be compressed until the weak spring 72 is completely compressed. The rotating rod 51 will be blocked by the stationary straight bar 71 and stop synchronously. During the period when the straight bar 71 is stationary, since the spring strip 8 will move with the rotating rod 51, the spring strip 8 located in the groove 74 of the groove bar will move towards the workpiece under the influence of the path in the groove. If the spring strip 8 contacts the workpiece, at this time, the length of the spring strip 8 is greater than its gap with the workpiece. Therefore, the spring strip 8 also undergoes local expansion and contraction during the blockage, and then closely adheres to the inner wall of the workpiece.

[0028] Refer to Figures 1-7 , two sliding grooves 511 are provided on the outside of the rotating rod 51. A convex block is arranged inside the rotating wheel 52. The surfaces of the convex block and the inside of the sliding groove 511 are both polished. The convex block is located inside the sliding groove 511.

[0029] Specifically, the width of the sliding groove 511 is equal to the width of the convex block, ensuring that the convex block inside the rotating wheel 52 can fit precisely. In order to ensure the smooth transmission of power between the rotating rod 51 and the rotating wheel 52, the surfaces of the convex block and the inside of the sliding groove 511 are both polished, such as high-precision grinding, polishing, etc., to reduce the surface roughness. Then, when the rotating wheel 52 rotates, the rotating rod 51 can respond in a timely manner. When the rotating rod 51 moves up and down, the smooth surface reduces the friction between the two, avoiding component wear caused by friction.

[0030] Refer to Figures 1-5 , a spacer push rod 31 is arranged on one side of the feeder 3. The output end of the blocking rod 13 is connected to a blocking plate 131. A reactor 132 is installed on the blocking plate 131. The feeder 2, the reactor 132, the telescopic rod 12, the blocking rod 13 and the servo motor 10 are coupled. The outside of the feeder 2 is a conveyor belt with a smooth surface. The blocking rod 13 blocks the workpiece through the blocking plate 131. At the same time, the blocking plate 131 can be adjusted in position on the top of the blocking rod 13 to adapt to workpieces of different sizes. When the workpiece is blocked and contacts the reactor 132, the telescopic rod 12 contracts and the feeder 2 stops conveying. Subsequently, after the telescopic rod 12 is completely contracted, the blocking rod 13 extends to drive the blocking plate 131 to move upward to avoid affecting the rotation of the workpiece. Then, after the servo motor 10 rotates two weeks, the telescopic rod 12 extends. After the telescopic rod 12 is completely extended, the feeder 2 starts, and at the same time, the blocking rod 13 contracts for the next operation.

[0031] Among them, the reactor 132 can be Balluff BALLUFF BES515-114-S4-C3, which can adapt to a variety of industrial scenarios, is presumably of a high protection level, can adapt to a certain harsh industrial environment, is commonly used for object detection and positioning in industrial automation production, and is suitable for detecting medium-sized industrial special-shaped die accessories.

[0032] Referring to Figures 2-5 , the bottom end of the spring strip 8 is located inside the groove strip 74. The number and position of the spring strips 8 correspond one-to-one with those of the groove strip 74. The outer sides of the spring strips 8 and the bottom of the straight strip 71 are both treated with high friction. Specifically, the straight strip 71 will contact the top surface of the workpiece after moving downward, and the spring strip 8 will also be further closely attached to the inside of the workpiece due to extrusion. And because both of them are treated with roughness, the workpiece can be effectively driven to rotate. Through the high-friction contact between the spring strip 8 and the surface of the workpiece, the stable driving of the workpiece can be realized, so that the workpiece rotates randomly due to inertia above the feeder 2 due to the friction force, and then secondary detection and sorting are carried out. Referring to Figures 2-6 , on one side of the top of the feeder 2, a first detector 21, a second detector 22, a third detector 23, a first push rod 201 and a second push rod 202 are provided. The first detector 21 is coupled to the first push rod 201, the second detector 22 is coupled to the second push rod 202. The support frame 4 is located between the first push rod 201 and the second push rod 202. The distance between the support frame 4 and the first push rod 201 is less than the distance between the support frame 4 and the second push rod 202, so that the rotated workpiece has a certain interval time when reaching the second detector 22 and is at rest at the same time, avoiding errors during sorting.

[0033] On the top of the machine body 1, a driving motor 101, a first receiving table 102 and a second receiving table 103 are provided. The output end of the driving motor 101 is connected to the feeder 2. The midline of the first receiving table 102 coincides with that of the first push rod 201, and the midline of the second receiving table 103 coincides with that of the second push rod 202.

[0034] Specifically, the first detector 21 performs detection to control the first push rod 201 to perform primary sorting, the second detector 22 performs local detection, controls the second push rod 202 to perform secondary sorting, the third detector 23 performs a third evaluation. The first push rod 201 will push the workpiece to the first receiving table 102, and the second push rod 202 will push the workpiece to the second receiving table 103.

[0035] Referring to Figures 3-8 , symmetrically arranged placement notches 401, guiding notches 402 and circular notches 403 are formed on the support frame 4. A circular notch 403 is formed at the top of the support frame 4. Both ends of the guiding rod 6 are respectively located inside the corresponding guiding notches 402, and the runner 52 is located inside the circular notch 403, all of which are used to limit the positions of components.

[0036] Referring to Figures 1-8 , a limiting rod 41 is arranged inside the placement notch 401. The pressing rod 91 is rotatably connected to the outside of the limiting rod 41, and the limiting rod 41 is used to limit and support the pressing rod 91.

[0037] The working principle of the present invention is as follows: The feeder 2 and the material conveyor 3 work together to convey workpieces. First, the first detector 21 on one side of the top of the feeder 2 conducts a first detection on the workpiece moving into the detection area. When a workpiece that does not meet the first sorting condition is detected, the first detector 21 sends a signal to the first push rod 201, and the first push rod 201 quickly extends to push the workpiece to the first receiving table 102 that coincides with its center line, completing the first sorting. When the workpiece meets the condition, it moves with the feeder 2. When the workpiece contacts the pressure rod 91, under the action of two weak torsion springs 92, the position of the workpiece is restricted to keep it at the center line position of the feeder 2 to avoid deviation. When the workpiece contacts the barrier plate 131 of the barrier rod 13 and triggers the reactor 132, the telescopic rod 12 contracts and the feeder 2 pauses briefly. At this time, the guide rod 6 loses support and moves downward synchronously, thereby driving components such as the connecting rod 5 connected to the guide rod 6 to move downward. During the downward movement, the inclined block 73 at the bottom end of the straight bar 71 and the spring strip 8 enter the workpiece. However, the fitting of the straight bar 71 with the top of the workpiece is blocked. The rotating rod 51 continues to move downward under the gravity of the weight 53 to compress the weak spring 72 until the weak spring 72 is completely compressed and the rotating rod 51 stops. During this period, the spring strip 8 moves with the rotating rod 51 and moves towards the workpiece under the action of the groove strip 74, closely fitting with the inner wall of the workpiece. At this time, multiple spring strips 8 and the straight bar 71 are all in contact with the workpiece. Subsequently, the barrier rod 13 extends to drive the barrier plate 131 to move upward to avoid affecting the rotation of the workpiece. Then, the servo motor 10 is started to rotate two weeks. The servo motor 10 drives the rotating wheel 52 to rotate through the transmission belt 11. The rotating wheel 52 drives the rotating rod 51 to rotate through the cooperation of the internal protrusion and the chute 511 of the rotating rod 51. Then, the workpiece is driven to rotate randomly by using the friction force between multiple spring strips 8 and the straight bar 71 and the workpiece. Subsequently, the workpiece continues to move with the feeder 2 to the detection area of the second detector 22. The second detector 22 detects the local details of the workpiece. When a workpiece that does not meet the secondary sorting condition is found, the second detector 22 issues an instruction to the second push rod 202, and the second push rod 202 acts to push the workpiece to the second receiving table 103 corresponding to its center line. At the same time, the barrier rod 13 contracts to drive the barrier plate 131 to move downward, while the qualified workpieces move and are fully detected again by the third detector 23.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
