Description

Technical Field

[0001] This utility model belongs to the field of workpiece production technology, and specifically relates to an automatic detection device for disc-shaped workpieces. Background Technology

[0002] In the manufacturing process of workpieces, to ensure the overall quality and performance of the products, multi-dimensional and high-precision quality inspection must be carried out on the workpieces before they leave the factory. This step is crucial. However, in many traditional manufacturing enterprises today, quality inspection still mainly relies on manual operation. Although manual inspection can meet basic quality control needs to a certain extent, the process is cumbersome and inefficient, usually requiring each workpiece to be inspected one by one.

[0003] Especially in mass production, companies often need to arrange multiple quality inspectors to work in shifts to maintain the testing progress. This not only significantly increases labor costs but also greatly limits the further improvement of testing efficiency. At the same time, manual inspection also has problems such as large human error and difficulty in unifying testing standards, resulting in insufficient consistency and reliability of test results, making it difficult to achieve comprehensive and accurate control over the entire testing process and key parameters.

[0080] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0081] like Figure 1 and Figure 9As shown, this solution provides an automatic inspection device for a disc-shaped workpiece 1. The workpiece 1 has a cylindrical boss 2 with a through hole 3.

The third detection unit 9 is used to detect the size of the through hole 3; the fourth detection unit 10 is located to the side of the third detection unit 9 and has a rotating seat 11 with a positioning element 12 and a limiting block 13 on the rotating seat 11. The positioning element 12 is movably inserted into the through hole 3 to provide positioning for the workpiece 1, and the limiting block 13 is movably abutted against the side wall of the workpiece 1 to provide limiting for the workpiece 1. The rotating seat 11 is used to drive the workpiece 1 to rotate. The fourth detection unit 10 is used to detect the height of the boss 2 and the thickness of the workpiece 1; the sorting unit 14 is located to the side of the fourth detection unit 10 and is used to classify and sort the workpieces 1 that have completed the detection.

[0082] During operation, the loading unit 5 loads workpiece 1, and the conveying unit 6 sequentially transfers workpiece 1 from the loading unit 5 to each inspection unit. First, the first inspection unit 7 performs visual inspection on workpiece 1 to check for defects in its shape. After visual inspection, the conveying unit 6 continues to transport workpiece 1 to the location of the second inspection unit 8, which inspects the outer diameter of the boss 2 on workpiece 1. After the outer diameter of the boss 2 is inspected, the conveying unit 6 continues to transport workpiece 1 to the location of the third inspection unit 9, which inspects the size of the through hole 3 on workpiece 1. After the size of the through hole 3 is inspected, the conveying unit 6 continues to transport workpiece 1 to the rotating seat 11. At this time, the positioning element 12 is inserted into the through hole 3, and the limiting block 13 abuts against the edge of workpiece 1. The positioning element 12 and the limiting block 13 maintain the position of the workpiece. 1. Precise positioning and limiting are performed. The fourth detection unit 10 begins to detect workpiece 1. During the detection process, the rotating seat 11 drives workpiece 1 to rotate, so that the fourth detection unit 10 can continuously measure the height of the boss 2 and the thickness of workpiece 1 around the entire circumference. At this point, all detection steps for workpiece 1 are completed. The transport unit 6 continues to transport workpiece 1 to the sorting unit 14, where workpiece 1 is classified and sorted.

The first detection unit 17 is used to detect whether the first station 16 has moved to a preset position, and the second detection unit 18 is used to detect whether workpiece 1 is placed on the first station 16 that has moved to the preset position. After the first detection unit 17 and the second detection unit 18 confirm that the first station 16 has reached the preset position and the workpiece 1 has been correctly placed, a signal is sent to the first drive unit 19. The first drive unit 19 receives the signal and stops driving, causing the conveyor chain 15 to stop running. At this time, workpiece 1 is within the gripping range of the conveying unit 6, which is convenient for subsequent processes to grip.

Next, the fourth drive unit 25 is activated, driving the support seat 26 to descend vertically, bringing the pneumatic gripper 20 to the gripping height. The pneumatic gripper 20 closes, completing the gripping of the workpiece 1. Subsequently, the air blowing unit 21 is activated and connected to an external air source to clean the surface of the gripped workpiece 1 with air, removing burrs or dust. Immediately afterwards, the second drive unit 23... The fourth drive unit 25 is activated again, driving the support base 26 to rise vertically, causing the pneumatic gripper 20 to lift the workpiece 1 away from the first station 16. Then, the third drive unit 24 continues to drive, driving the moving base 22 and its pneumatic gripper 20 away from the first station 16 horizontally. Subsequently, the second drive unit 23 continues to drive, driving the moving base 22 and its pneumatic gripper 20 to move in another horizontal direction, thereby realizing the overall transport of the workpiece 1.

Subsequently, the fifth drive unit 31 drives the first support 32 to move downward, causing the fourth detection element 30 to approach the cylindrical boss 2 of the workpiece 1. After the fourth detection element 30 contacts the boss 2, the fifth drive unit 31 continues to push the first support 32 downward, at which point the first slider 33 slides upward relative to the first support 32.

The first measuring element 34 records the displacement changes of the first push rod 35 in real time. The first slider 33 moves a certain distance; based on the contact state of the fourth detection element 30 with the boss 2 and the displacement data measured by the first measuring element 34, it can be comprehensively judged whether the outer diameter of the boss 2 meets the standard, and thus determine whether the workpiece 1 is qualified; after the inspection is completed, the fifth driving element 31 drives the first bracket 32 ​​to move up in the vertical direction, thereby driving the fourth detection element 30 away from the workpiece 1 and back to the initial position; wherein, the fourth detection element 30 is preferably a go / no-go gauge, the first measuring element 34 can be an electronic ruler or other measuring equipment, the first elastic element 36 is preferably a spring, and the fifth driving element 31 can be a motor, hydraulic cylinder or pneumatic cylinder.

[0093] Furthermore, the worktable 4 is also equipped with: a pressure block 44, which is movably positioned above the third station 29 and the fourth station, and movably abuts against the workpiece 1 at the third station 29 and the fourth station, for providing a limit for the workpiece 1; a seventh drive member 45, the pressure block 44 is connected to the output end of the seventh drive member 45, and the seventh drive member 45 is used to drive the pressure block 44 to move; ejector pins, the sides of the third station 29 and the fourth station are provided with through holes 46, each through hole 46 is movably inserted with an ejector pin, one end of the ejector pin movably abuts against the workpiece 1, for ejecting the workpiece 1 from the third station 29 and the fourth station respectively; and an eighth drive member 47, the output end of the eighth drive member 47 is connected to an ejector pin, and the eighth drive member 47 is used to drive the ejector pin to move in the vertical direction.

[0094] When the fourth and fifth detection elements 30 and 37 complete the detection of workpiece 1 at the third and fourth stations respectively and begin resetting, in order to prevent the fourth and fifth detection elements 30 and 37 from causing unexpected displacement of workpiece 1 as they move away from it, the seventh drive element 45 is activated, driving the pressure block 44 to move downward and contact workpiece 1, thereby limiting workpiece 1 in the vertical direction; after the fourth and fifth detection elements 30 and 37 complete the resetting, the seventh drive element 45 is activated again, driving the pressure block 44 to move upward and away from workpiece 1. This returns the workpiece to its initial position to avoid affecting the subsequent gripping operation of the pneumatic gripper 20 on the workpiece 1. When the pneumatic gripper 20 grips the workpiece 1 at the third station 29 and the fourth station, in order to prevent the workpiece 1 from being stuck to the surface of the third station 29 and the fourth station due to adsorption or friction, causing gripping difficulties, the eighth drive unit 47 is activated, driving the ejector pin to extend through the through hole 46 and contact the bottom of the workpiece 1, slightly pushing the workpiece 1 out so that the pneumatic gripper 20 can grip it smoothly.

[0096] When the pneumatic gripper 20, driven by the conveying unit 6, transports the workpiece 1, whose through hole 3 size has been inspected, to the rotating seat 11, the positioning element 12 is inserted into the through hole 3 of the workpiece 1, and the limiting block 13 contacts the edge of the workpiece 1, achieving precise positioning and limiting of the workpiece 1. Subsequently, the ninth driving element 50 is activated, driving the third support 51 to move downward, so that the sensing ends of the sixth detection element 48 and the seventh detection element 49 contact the top of the boss 2 and one side of the workpiece 1 in the vertical direction, respectively. After stable contact is achieved, the tenth driving element 52 is activated, driving the rotating seat 11 and the workpiece 1 to rotate one revolution. During this process, the sixth detection element 48 and the seventh detection element 49 continuously measure the height dimension of the entire circle of the boss 2 and the thickness dimension of the entire circle of the workpiece 1, and record the detection data. Based on these measurement values, a comprehensive judgment is made on whether the workpiece 1 is qualified. Among them, the sixth detection element 48 and the seventh detection element 49 can be electronic rulers or other measuring elements, the ninth driving element 50 can be a motor, hydraulic cylinder or pneumatic cylinder, and the tenth driving element 52 is preferably a rotary motor.

[0097] Further, the sorting unit 14 includes: a first conveyor belt 53, located to the side of the fourth detection unit 10, for receiving and transporting workpieces 1 that have completed all detection steps; a rejection element 54, movably disposed to the side of the first conveyor belt 53, for rejecting defective products from the first conveyor belt 53; an eleventh drive element 55, the rejection element 54 being connected to the output end of the eleventh drive element 55, the eleventh drive element 55 being used to drive the rejection element 54 to move; a second conveyor belt 56, disposed opposite to the rejection element 54 on both sides of the first conveyor belt 53, for receiving defective products; an oil tank 57, located to the side of the first conveyor belt 53, the oil tank 57 being provided with a twelfth drive element 58 and a lifting block 59 connected to the output end of the twelfth drive element 58, the lifting block 59 having a first working position and a second working position, the twelfth drive element 58 being used to drive the lifting block 59 to switch between the first working position and the second working position; when the lifting block 59... When the lifting block 59 is in the first working position, it is flush with the first conveyor belt 53; when the lifting block 59 switches from the first working position to the second working position, it is used to drive the workpiece 1 into the oil immersion area for oil immersion treatment; the third push rod 60 is movably disposed above the first conveyor belt 53, and the third push rod 60 has a first part 61 and a second part 62 arranged side by side. The first part 61 is movably inserted into the through hole 3 of the workpiece 1, and is used to push the workpiece 1 to be immersed in oil away from the first conveyor belt 53. The second part 62 is movably abutted against the workpiece 1 on the lifting block 59, and is used to push the workpiece 1 that has completed the oil immersion operation away from the lifting block 59; the thirteenth drive member 63 is connected to the output end of the third push rod 60, and the thirteenth drive member 63 is used to drive the third push rod 60 to move in the horizontal direction; the fourteenth drive member 64 is connected to the fourteenth drive member 64, and the fourteenth drive member 64 is used to drive the thirteenth drive member 63 to move in the vertical direction.

[0098] Driven by the conveying unit 6, the pneumatic gripper 20 transports the workpiece 1, which has completed all inspection steps, to the first conveyor belt 53. The first conveyor belt 53 is driven by a stepper motor 65, which is electrically connected to the first inspection unit 7, the second inspection unit 8, the third inspection unit 9, and the fourth inspection unit 10. Based on the inspection results of the workpiece 1 and the preset sorting conditions, the stepper motor 65 can precisely control the running distance of the first conveyor belt 53 and accurately transport the unqualified workpiece 1 to the position corresponding to one end of the second conveyor belt 56. Subsequently, the eleventh drive unit 55 is activated, which drives the rejection unit 54 to push the workpiece 1 onto the second conveyor belt 56. The second conveyor belt 56 can run continuously or intermittently, carrying the unqualified workpiece 1 forward to make room for the newly entering workpiece 1, ensuring smooth continuous operation.

[0099] A stepper motor 65 is an open-loop control element that converts electrical pulse signals into mechanical angular or linear displacement. Each time an electrical pulse is input, the motor's rotor rotates by a fixed angle, called the "step angle." By controlling the number and frequency of the electrical pulses and the phase sequence of the motor windings, precise control of the stepper motor 65's positioning, speed, and rotation direction can be achieved.

[0100] The first conveyor belt 53 continues to transport the qualified workpiece 1 to the position of the third push rod 60. In the initial state, the third push rod 60 is located above the first conveyor belt 53, and the lifting block 59 is in the first working position and flush with the first conveyor belt 53. When the first conveyor belt 53 transports the first qualified workpiece 1 to below the third push rod 60, the fourteenth drive unit 64 is activated, driving the thirteenth drive unit 63 and its third push rod 60 to move downward, so that the first part 61 of the third push rod 60 inserts into the workpiece 1. Subsequently, the fourteenth drive unit 64 stops running, and the thirteenth drive unit 63 is activated, driving the third push rod 60 to move horizontally, smoothly pushing the workpiece 1 onto the lifting block 59 through the first part 61. After the pushing is completed, the thirteenth drive unit 63 and the fourteenth drive unit 64 work together to reset the third push rod 60 to the initial position, preparing for the next operation. At the same time, the twelfth drive unit 58 is activated. The lifting block 59 is lowered from the first working position to the second working position, thereby bringing the workpiece 1 into the oil immersion area inside the oil tank 57 to complete the oil immersion process. After the oil immersion is completed, the twelfth drive unit 58 reverses its direction, driving the lifting block 59 back to the first working position. At this time, the first conveyor belt 53 transports the next workpiece 1 to be immersed in oil to below the third push rod 60. The fourteenth drive unit 64 starts again, driving the thirteenth drive unit 63 and the third push rod 60 to descend, so that the first part 61 is inserted into the new workpiece 1, while the second part 62 is located to the side of the lifting block 59. Subsequently, the thirteenth drive unit 63 starts, driving the third push rod 60 to move horizontally. The second part 62 pushes out the workpiece 1 that has been immersed in oil from the lifting block 59, while the first part 61 pushes the new workpiece 1 to be immersed in oil onto the lifting block 59. The twelfth drive unit 58 starts again, driving the lifting block 59 to descend, repeating the above oil immersion process to achieve continuous cycle operation.

[0101] Furthermore, the sorting assembly also includes: a collection component 66, located to the side of the oil tank 57; a baffle 67 and a pusher 68 movably disposed on the collection component 66, the baffle 67 and the pusher 68 being disposed opposite each other to form a material channel 69, the lifting block 59 being flush with the feed end of the material channel 69 when it is in the first working position, the material channel 69 being used to allow the oil-soaked workpiece 1 to flow into the collection component 66 in an orderly manner; an eighth detection component 70, disposed on the collection component 66 and located above the material channel 69, for detecting whether the material channel 69 is full; a fifteenth drive component 71, the baffle 67 being connected to the output end of the fifteenth drive component 71, the fifteenth drive component 71 being electrically connected to the eighth detection component 70, for driving the baffle 67 to rise and fall; and a sixteenth drive component 72, the pusher 68 being connected to the output end of the sixteenth drive component 72, the sixteenth drive component 72 being used to drive the pusher 68 to move in the horizontal direction.

[0102] When the lifting block 59 is in the first working position, one side of it is flush with the first conveyor belt 53, and the other side is flush with the material channel 69. At this time, the second part 62 of the third push rod 60 pushes the oil-soaked workpiece 1 off the lifting block 59 and into the material channel 69. The width of the material channel 69 is designed to be 1 to 1.5 times the diameter of the workpiece 1, allowing only workpieces 1 to pass through in a single row. The incoming workpieces 1 are pushed forward by the subsequent workpieces 1. When the eighth detection element 70 detects that the material channel 69 is full, it will send a corresponding electrical signal to the control system. After receiving the signal, the control system triggers the fifteenth drive element 71 and the sixteenth drive element 72 to work together. The fifth drive component 71 is activated first, causing the baffle 67 to rise upward, forming a discharge gap in the material channel 69. Subsequently, the sixteenth drive component 72 is activated, causing the pusher plate 68 to move horizontally, pushing the neatly arranged rows of workpieces 1 in the material channel 69 to the empty area of ​​the second collection component 66. After the pushing is completed, the sixteenth drive component 72 drives the pusher plate 68 back to the initial position, and the fifteenth drive component 71 drives the baffle 67 to reset, restoring the structural integrity of the material channel 69 and preparing for the next batch of workpieces 1 to enter. Among them, the eighth detection component 70 is preferably a photoelectric sensor, and the fifteenth drive component 71 and the sixteenth drive component 72 can be a motor, a hydraulic cylinder, or a pneumatic cylinder.
