[0035] The core of the utility model is to provide an automatic flaw detection and sorting device, which is easy to operate, can realize automatic detection and sorting, improve efficiency and reduce costs.
[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0037] The automatic flaw detection and sorting device provided by the present invention first places the cylinder sleeve and other parts 100 into the loading track 12 by the loading robot 11, and the parts 100 wait for inspection in the inspection pool 121 of the loading track 12. The transfer component 5 grabs the parts 100 waiting for inspection one at a time in sequence and places them into the first tray 33 of the turntable component 3. At this time, after the shaft roller sensor 37 senses that there are parts 100 on the first tray 33, it immediately starts the arm motor 32 to rotate the first tray 33 together with the parts 100 therein by 180 degrees to the inspection position, and the second tray 34 originally at the inspection position is transferred to the original inspection position. When the shaft roller sensor 37 finds that the second tray 34 at the inspection position is empty, the transfer component 5 grabs the part 100 in the loading track 12 and moves the part 100 to the second tray 34; at the same time, there is a flaw detection component 2 at the inspection position. When it is found that there are parts 100 at the inspection position, the flaw detection component 2 will emit rays The device 22 moves to a set position inside the part 100, generally in the middle of the inner hole of the part 100. When the part 100 starts to rotate, the X-ray starts to emit rays to detect the part 100. After the rotation angle is 360°, the flaw detection is completed. After the flaw detection is completed, the ray emitter 22 automatically withdraws the part 100 and returns to the original position of the ray emitter 22. At this time, when it is sensed that there are parts 100 in the second tray 34, the arm motor 32 moves the second tray 34 together with the parts 100 to the detection position, and the first tray 33 leaves the flaw detection component 2. This cycle is repeated to achieve the purpose of continuous production. The parts 100 after flaw detection are grabbed by the transfer component 5, judged according to the flaw detection results, and placed in the first unloading track 41 or the second unloading track 42 for automatic separation. Then the unloading robot 43 classifies the parts 100 in the first unloading track 41 or the second unloading track 42 according to whether they are qualified or not and stores them in the corresponding packaging boxes 433.

The unloading robot 43 is inclined so that the part 100 can roll into the waiting pool; specifically, the unloading robot 43 includes an unloading gripper 431 and an unloading mechanical arm 432. The unloading gripper 431 is installed on the unloading mechanical arm 432. The unloading mechanical arm 432 can use the unloading gripper 431 to take the part 100 out of the waiting pool of the first unloading track 41 or the second unloading track 42; the first unloading track 41 and the second unloading track 42 are inclined downward from one end close to the turntable assembly 3 toward the other end, and can achieve unloading with the help of the gravity of the part 100 itself. Furthermore, the dimensions of the first unloading track 41 and the second unloading track 42 are the same as those of the loading track 12. The loading track 12 is separated from the first unloading track 41 and the second unloading track 42 by one end distance, which facilitates the arrangement of the turntable assembly 3. The loading track 12 is located on one side of the turntable assembly 3, and the first unloading track 41 and the second unloading track 42 are located on the other side of the turntable assembly 3.
[0043] In the automatic flaw detection and sorting device, the part 100 is preferably a cylindrical part 100, for example, a cylinder sleeve, and the part 100 can automatically roll down in the loading track 12, the first unloading track 41 or the second unloading track 42 by rolling; the part 100 is obtained by the loading component 1, and the part 100 is moved from the loading component 1 to the turntable component 3 by the transfer component 5, and then the turntable component 3 moves the part 100 to the corresponding position of the flaw detection component 2, and the flaw detection component 2 is used to perform flaw detection on the part 100 located on the turntable component 3. After the detection is completed, the detection result of the flaw detection component 2 is obtained by the central control computer to determine whether the part 100 is qualified Parts 100, and then the parts 100 located on the turntable component 3 are classified by the transfer component 5, and transferred to the unloading and packaging component 4, the qualified parts 100 are boxed, and the unqualified parts 100 are subsequently processed; the automatic flaw detection and sorting device can realize the automatic loading and unloading operation of the parts 100, and by tilting the loading track 12, the first unloading track 41 and the second unloading track 42, the gravity of the parts 100 themselves is used to roll them into the inspection pool 121 or the waiting pool, which can effectively improve efficiency, avoid interference from human factors, realize automatic flaw detection of the parts 100 and judgment of whether they are qualified, improve accuracy, and facilitate batch detection.
[0044] In some embodiments, the loading assembly 1 further includes a first loading sensor and a second loading sensor. A loading baffle 14 is further provided on the side of the loading track 12 close to the inspection tank 121. The first loading sensor corresponds to the position of the loading baffle 14 and is used to detect whether there are parts 100 at the front end of the loading baffle 14. The second loading sensor corresponds to the position of the inspection tank 121 and is used to detect whether there are parts 100 in the inspection tank 121. Furthermore, the loading assembly 1 further includes a third loading sensor 13 for sensing and counting parts 100. The third loading sensor 13 is installed on the side of the loading track 12 close to the loading robot 11 to facilitate counting the number of parts 100. Specifically, the central control machine obtains the sensing signals of the first and second loading sensors to facilitate the control of the loading baffle 14; when the second loading sensor detects that there are no parts 100 in the inspection tank 121, the switch of the loading baffle 14 is turned on, and the loading baffle 14 is controlled to open automatically, so that the parts 100 can roll into the inspection tank 121. When the second loading sensor senses that there are parts 100 in the inspection tank 121, it notifies the switch of the loading baffle 14 to close, and the baffle automatically rises to block the parts 100, preventing the parts 100 from continuing to fall into the inspection tank 121 and affecting the material collection of the transfer component 5. When the second loading sensor senses that there are parts 100 in the inspection tank 121, and the first loading sensor senses that there are parts 100 at the front end of the loading baffle 14, the central control machine controls the transfer component 5 to collect the materials and then controls the loading baffle 14 to open. Of course, only a second loading sensor can be set up to determine whether there is a part 100 in the inspection pool 121. If there is a part 100, the loading baffle 14 is controlled to be closed and in a blocking state. If there is no part 100, the loading baffle 14 is controlled to be open and in a non-blocking state.
[0045] In some embodiments, a recessed portion is provided in the middle of the loading track 12 along the width direction, that is, the loading track 12 has a structure with convex sides and a recessed middle along the width direction, and the part 100 is placed in the recessed portion. The part 100 is a columnar structure, and the axial direction of the part 100 is perpendicular to the extension direction of the loading track 12. The width of the recessed portion can be set according to the size of the part 100; for example, the width of the recessed portion is larger than the length of the part 100 along the axial direction by a preset size, and the preset size can be 4-6 cm, to ensure that the part 100 can roll down smoothly.
[0046] In some embodiments, the loading track 12 is tilted downward at an angle of 5-10° from the loading position to the inspection tank 121. This tilt angle can not only ensure that the part 100 rolls smoothly into the inspection tank 121, but also prevent the part 100 from escaping from the inspection tank 121 due to excessive tilt angle.
[0047] In some embodiments, the first unloading track 41 and the second unloading track 42 are tilted downward from one end close to the turntable assembly 3 toward the waiting pool at an angle of 5-10 degrees; similarly, this tilt angle can not only ensure that the part 100 rolls smoothly into the waiting pool, but also prevent the part 100 from falling out of the waiting pool due to excessive tilt angle.

The extension and retraction of the cylinder drives the left gripping plate and the right gripping plate on both sides to clamp and grab the part 100. Of course, the cylinder can also be replaced by other driving parts. For example, the transfer gripper 55 includes a left gripping plate, a right gripping plate and an electric telescopic part located between the left gripping plate and the right gripping plate. The electric telescopic parts such as the cylinder are connected to the central control machine for easy control.
[0049] In some embodiments, the part 100 is a cylinder liner, and the inspection pool 121 is an arc-shaped groove arranged on the loading track 12, so that the part 100 can stop after rolling into the arc-shaped groove, which is convenient for the subsequent transfer component 5 to obtain the part 100; the waiting pool is an arc-shaped groove arranged on the first unloading track 41 or the second unloading track 42, which ensures that the cylinder liner can remain stationary after entering the waiting pool, which is convenient for the subsequent unloading robot 43 to pick up the material.
[0050] In some embodiments, the unloading and packaging component 4 further includes a first unloading sensor and a second unloading sensor. The first unloading track 41 and the second unloading track 42 are both provided with the first unloading sensor and the second unloading sensor. The first unloading sensor corresponds to the position of the unloading baffle and is used to detect whether there is a part 100 at the front end of the unloading baffle. The second unloading sensor corresponds to the position of the waiting pool and is used to detect whether there is a part 100 in the waiting pool. When the first unloading sensor detects that there is a part 100 at the front end of the unloading baffle and the second unloading sensor detects that there is a part 100 in the waiting pool, When the sensor detects that there are no parts 100 in the waiting pool, the central control machine controls the unloading baffle to open; when the first unloading sensor detects that there are parts 100 at the front end of the unloading baffle, and the second unloading sensor detects that there are parts 100 in the waiting pool, the central control machine controls the unloading robot 43 to pick up the materials, and after the unloading robot 43 picks up the materials, controls the unloading baffle to open; when the first unloading sensor detects that there are no parts 100 at the front end of the unloading baffle, and the second unloading sensor detects that there are no parts 100 in the waiting pool, the central control machine controls the unloading baffle to open. Similarly, the unloading and packaging component 4 also includes a third unloading sensor 44 for sensing and counting qualified parts 100 and unqualified parts 100 respectively. The third unloading sensor 44 is provided on both the first unloading track 41 and the second unloading track 42. The third loading sensor 13 is installed on the side of the first unloading track 41 and the second unloading track 42 close to the turntable component 3, so as to facilitate the counting of the number of qualified parts 100 and unqualified parts 100 respectively. Of course, only a second unloading sensor can be set to judge whether there is a part 100 in the waiting pool. If there is a part 100, the unloading baffle is controlled to be closed and in a blocking state. If there is no part 100, the unloading baffle is controlled to be open and in a non-blocking state.
[0051] Furthermore, when the first unloading track 41 senses the presence of a part 100 in the waiting pool, the unloading robot 43 is notified to start grabbing the part 100 and placing it in the packaging box 433. If no part 100 is detected, the unloading flap switch opens, the flap retracts, and the part 100 automatically rolls into the waiting pool. When the second unloading track 42 senses the presence of a part 100 in the waiting pool, the unloading robot 43 is notified, and the unloading robot 43 starts the reject program and places the part into the reject box.
[0052] In some embodiments, the turntable assembly 3 includes a support arm 31, a support arm motor 32, a first tray 33 and a second tray 34. The support arm 31 is installed on the support arm motor 32. The support arm motor 32 can drive the support arm 31 to rotate. The support arm motor 32 can drive the support arm 31 to rotate 180 degrees. The first tray 33 and the second tray 34 are respectively located at both ends of the support arm 31; the first tray 33 and the second tray 34 are each provided with at least two rollers 35 and a roller motor 36 for driving the rollers 35 to rotate. The rotation of the rollers 35 drives the part 100 to rotate; and the distance between adjacent rollers 35 is adjustable to place parts 100 of different sizes. The axial direction of the rollers 35 is parallel to the axial direction of the part 100, and the circumference of the part 100 is placed on the rollers 35. The rotation of the two rollers 35 can drive the part 100 to rotate around its axial direction, which is convenient for flaw detection of the inside and outside of the part 100.
[0053] In some embodiments, a roller sensor 37 is also included at the bottom of the roller 35. The roller sensor 37 is connected to the central control machine. The central control machine is used to control the roller motor 36 to start when the roller sensor 37 can sense the part 100. The roller sensor 37 is used to determine whether the part 100 is placed in place, thereby realizing automatic control and facilitating operation.
[0054] In some embodiments, the flaw detection assembly 2 includes a safety protection device 21, a ray emitter 22 and a flaw detection cylinder 23. The ray emitter 22 is installed on the flaw detection cylinder 23. The flaw detection cylinder 23 can drive the ray emitter 22 to move into the part 100. The safety protection device 21 is covered on the outside of the ray emitter 22 and the flaw detection cylinder 23. Specifically, when the roller sensor 37 senses that there is a part 100 in the tray, the arm motor 32 is started, and the arm 31 with the part 100 is rotated 180 degrees and then stopped. At this time, the flaw detection cylinder 23 is started, and the flaw detection cylinder 23 pushes the ray emitter 22 to move into the part 100. At the same time, the roller motor 36 is started, and the roller motor 36 rotates with the two rollers 35, thereby driving the part 100 to make a circular motion on the roller 35. When the roller motor 36 is started, the linear array switch in the ray emitter 22 is started, and the flaw detection begins. When the part 100 rotates one circle, the roller motor 36 and the linear array switch are turned off at the same time, and the flaw detection cylinder 23 is started and retracted to the standby state.
[0055] In some embodiments, the safety guard 21 is provided with a protective baffle 211 that can be opened and closed longitudinally. The protective baffle 211 is provided with a baffle driver that is connected to the central control machine.

[0057] The transfer motor is running, and the retractable device moves along the left and right rails 52. When it reaches the set position, the central control machine notifies the retractable rod 54 on the retractable device to open and move downward. When it reaches the set position, the transfer gripper 55 is opened to grab the cylinder liner in the inspection tank 121. At this time, the retractable rod 54 is retracted, and the retractable device moves to the right along the left and right rails 52 with the part 100. When it reaches the middle position of the transfer left and right rails 52, the retractable device moves forward along the front and rear rails 53. When it reaches the set position, the retractable device notifies the retractable rod 54 to open again. The retractable rod 54 extends. When the retractable rod 54 reaches the set position, the transfer gripper 55 is opened and the part 100 is placed on the first tray 33 or the second tray 34 of the turntable assembly 3.
[0058] When the sensor under the first tray 33 or the second tray 34 senses the presence of the parts 100, the central control machine notifies the motor 32 to open. The motor 32 starts to operate and opens the protective baffle 211 to allow the arm 31 to pass through. The arm 31 rotates 180 degrees with the first tray 33 or the second tray 34 on it. At this time, the motor 32 stops.
[0059] When the sensor of the roller 35 senses the presence of the part 100, the flaw detection cylinder 23 moves forward with the ray emitter 22 into the inner hole of the part 100. At this time, the central control machine starts the movement of the two rollers 35. Due to the movement of the rollers 35, the part 100 on them rotates at the same time, and the ray emitter 22 opens at the same time to perform flaw detection. When the flaw detection is completed, the ray emitter 22 and the flaw detection cylinder 23 automatically retract to their original positions. At this time, the roller 35 also stops rotating. The central control machine notifies the protective baffle 211 to open, and the support arm motor 32 starts at the same time. After rotating 180 degrees in the opposite direction of the direction of arrival, the support arm motor 32 stops working.
[0060] For the part 100 in the pallet that has completed the flaw detection, the transfer component 5 is notified to grab the part 100 and place it on the corresponding unloading track according to the flaw detection result. If it is qualified, it is placed on the first unloading track 41; if it is unqualified, it is placed on the second unloading track 42. When the part 100 is placed on the first unloading track 41 or the second unloading track 42, the part 100 rolls to the unloading baffle at the end of the track by its own gravity. When the first unloading sensor of the unloading baffle senses the presence of the part 100 and the second unloading sensor under the waiting pool senses that there is no part 100, the unloading baffle will be opened and the part 100 will automatically roll into the waiting pool; the second unloading sensor under the waiting pool detects the presence of the part 100, automatically starts the unloading robot 43 to grab the part 100, and places it in the packaging box 433, or starts the unqualified product program, and this cycle is completed; the next cylinder liner is processed in the same way.
