Description

Technical Field

[0001] The present invention belongs to the technical field of rubber parts sorting, and in particular relates to an automatic visual inspection and sorting device for rubber parts. Background Art

[0002] Rubber parts are product accessories made of rubber. Rubber has excellent flexibility, sealing and insulation properties and is widely used in many industries.

[0003] During the production process, rubber parts need to undergo a series of appearance inspections, such as those for cracks and bulges. Only qualified products that meet the requirements can be sold. However, inspection work is usually done manually. A large number of products often cause workers to perform repetitive work, resulting in both mental and physical fatigue. This is not only harmful to human health, but also affects the effectiveness of inspections. Therefore, it is necessary to design a sorting device that can perform automated inspections.

[0048] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0049] Example 1

[0050] like Figure 1-11 As shown, an automatic visual inspection and sorting device for rubber parts includes:

[0051] Rack 1;

[0052] The conveying mechanism is provided on the frame 1 and includes a No. 1 conveyor 2, a No. 2 conveyor 3 and a No. 3 conveyor 4 for conveying rubber parts;

[0053] The front and back recognition mechanism 6 is provided on the No. 1 conveyor 2 and is used to ensure that the rubber piece moves on the No. 1 conveyor 2 with the front side facing upwards. The front and back recognition mechanism 6 removes the rubber piece with the front side facing downwards from the No. 1 conveyor 2;

[0054] The front detection mechanism 7 is provided on the first conveyor 2 and is used to detect the appearance of the front of the rubber part;

[0055] The turning mechanism 8 is located between the No. 1 conveyor 2 and the No. 2 conveyor 3 and is used to turn the rubber piece on the No. 1 conveyor 2 180 degrees and place it on the No. 2 conveyor 3;

[0056] The reverse side detection mechanism 9 is provided on the second conveyor 3 and is used to detect the appearance of the reverse side of the rubber part;

[0057] The translation mechanism 10 is located between the second conveyor 3 and the third conveyor 4 and is used to translate the rubber parts on the second conveyor 3 and place them on the third conveyor 4;

[0058] The first crack detection mechanism 11 is used to detect cracks on the front surface of the rubber part;

[0059] The first ring groove detection mechanism 12 is used to detect the ring groove on the rubber part;

[0060] The second ring groove detection mechanism 13 is used to detect the ring groove on the rubber part;

[0061] The second crack detection mechanism is used to detect cracks on the reverse side of the rubber parts;

[0062] The moving mechanism 14 is used to transfer the rubber parts in sequence between the No. 3 conveyor 4, the No. 1 crack detection mechanism 11, the No. 1 ring groove detection mechanism 12, the No. 2 ring groove detection mechanism 13 and the No. 2 crack detection mechanism, and flip the rubber parts between the No. 1 ring groove detection mechanism 12 and the No. 2 ring groove detection mechanism 13.

[0063] In the above embodiment, the rubber piece is a tubular structure with an annular groove on the side, with its two ends being the front and back, respectively, and both the front and back sides are marked. The rubber piece is continuously conveyed to the No. 1 conveyor 2 by a conveying mechanism, so that the rubber piece moves synchronously with the No. 1 conveyor 2. When the rubber piece moves to the surface recognition mechanism 6, the surface recognition mechanism 6 is triggered, and the surface recognition mechanism 6 scans and analyzes the rubber piece. If the rubber piece meets the set requirements, it continues to pass. When the rubber piece moves to the front detection mechanism 7, the front detection mechanism 7 is triggered, and the front detection mechanism 7 performs an appearance inspection on the front side of the rubber piece. Rubber pieces that meet the standards continue to move to the flipping mechanism 8. The flipping mechanism 8 flips the rubber piece on the No. 1 conveyor 2 vertically 180° and places it on the No. 2 conveyor 3. At this time, the back side of the rubber piece faces upward, and the rubber piece moves along the No. 2 conveyor 3 to the back detection mechanism 9. The back detection mechanism 9 performs an appearance inspection on the back side of the rubber piece. After passing the inspection, the rubber parts are moved to the translation mechanism 10, and the translation mechanism 10 translates the rubber parts and places them on the No. 3 conveyor 4. The rubber parts on the No. 3 conveyor 4 are moved in sequence to the No. 1 crack detection mechanism 11, the No. 1 ring groove detection mechanism 12 and the No. 2 ring groove detection mechanism 13 through the moving mechanism 14.

[0064] As a further solution of the present invention, the front and back side identification mechanism 6 includes a No. 1 sensor 15, a No. 1 blower 16, a No. 1 collecting tube 17 and a visual detector 18. When the No. 1 sensor 15 senses that the rubber part passes by, the visual detector 18 starts to identify the rubber part. When the front side of the rubber part is facing upward, the No. 1 blower 16 is not started. When the front side of the rubber part is not facing upward, the No. 1 blower 16 starts to blow the rubber part into the No. 1 collecting tube 17.

[0065] In the above embodiment, as a rubber piece moves along conveyor 2, it passes sensor 15. Once sensor 15 detects the rubber piece, visual inspection 18 activates to inspect the top surface of the rubber piece. If visual inspection 18 detects the rubber piece facing upward, it passes. If visual inspection 18 detects the rubber piece facing away, blower 16 activates, blowing air from blower 16 into collection drum 17, where it is recovered and transported back to conveyor 2 for a second inspection.

[0066] As a further solution of the present invention, the front detection mechanism 7 and the back detection mechanism 9 both include several visual detectors 19, each visual detector 19 is provided with a No. 2 sensor 20, a No. 2 blower 21 and a No. 2 collecting tube 22. When the No. 2 sensor 20 senses that a rubber part passes by, the visual detector 19 starts to detect the rubber part. When the appearance of the rubber part meets the requirements set by the program, the blower does not start. When the appearance of the rubber part does not meet the requirements set by the program, the blower starts to blow the rubber part into the No. 2 collecting tube 22.

[0067] In the above embodiment, rubber parts, along conveyor No. 1 2, sequentially pass through multiple visual detectors 19 at the front inspection mechanism 7, and along conveyor No. 2 3, sequentially pass through multiple visual detectors 19 at the back inspection mechanism 9. These visual detectors 19 inspect the rubber parts for appearance defects such as cracks and missing material, flow marks, mold contamination from impurities, bulging at injection points, stretching at injection points, rubber stripping, frozen defects, bulging, rotting bubbles, aged rubber, and burrs. When the rubber parts reach sensor No. 2 20, the visual detectors 19 are activated. After the inspection, if the rubber parts do not meet the requirements, the blower No. 2 21 is activated to blow the rubber parts into the collection drum No. 2 22. Rubber parts that pass the inspection continue to move along conveyors No. 1 2 and No. 2 3.

[0068] As a further embodiment of the present invention, the flip mechanism 8 includes a mounting plate, a No. 1 cylinder 23, a No. 1 motor 24, a No. 1 robotic arm 25, and two clamping blocks 26 provided on the No. 1 robotic arm 25. The No. 1 cylinder 23 drives the No. 1 robotic arm 25 to move.

[0069] The second counting sensor 27 and the stop cylinder 28 are also included. The stop cylinder 28 is used to stop the movement of the rubber member.

[0070] In the above embodiment, the stop cylinder 28 is activated and extended, blocking the moving rubber pieces on conveyor 1 2. When the rubber pieces move along conveyor 1 2 to the second counting sensor 27 , the second counting sensor 27 is triggered. When the number of rubber pieces arranged and held stationary on conveyor 1 2 reaches a set value, the stop cylinder 28 is retracted, allowing the set number of rubber pieces on conveyor 1 2 to continue moving, and the turnover mechanism 8 is then activated. After the arranged rubber pieces pass the stop cylinder 28 , the stop cylinder 28 re-extends and stops the rubber pieces on conveyor 1 2 again.

[0071] Cylinder 1 (23) in the flipping mechanism 8 lowers arm 1 (25) and two clamps (26) to a set height. Arm 1 (25) then drives the two clamps (26) toward the rubber pieces, clamping them. Motor 1 (24) then rotates arm 1 (25) 180°, causing the rubber pieces to flip vertically 180° and move onto conveyor 2 (3), with the reverse side facing upward.

[0072] As a further solution of the present invention, the translation mechanism 10 includes a mounting plate, a No. 2 cylinder, a No. 2 motor, a No. 2 robotic arm, two clamping blocks 26 provided on the No. 2 robotic arm, a base, a No. 1 slider 29 provided on the base, and a No. 3 cylinder 30 for driving the No. 1 slider 29 to move. The two clamping blocks 26 on the No. 2 robotic arm clamp the rubber parts on the No. 2 conveyor 3, the No. 2 cylinder drives the No. 2 robotic arm to lift, and then the No. 2 motor drives the No. 2 robotic arm to rotate, and cooperates with the No. 3 cylinder 30 to drive the No. 1 slider 29 to move on the base, thereby transferring the rubber parts from the No. 2 conveyor 3 to the No. 3 conveyor 4.

[0073] In the above embodiment, the translation mechanism 10 has similar functions to the flip mechanism 8, except that the translation mechanism 10 is additionally provided with a No. 3 cylinder 30, which can drive the No. 2 robotic arm to move horizontally on the base, producing a dual effect of horizontal displacement.

[0074] As a further solution of the present invention, the first crack detection mechanism 11 and the second crack detection mechanism each include a moving component, a visual detector 31 and two detection components;

[0075] The detection assembly includes a No. 1 mounting frame, which is provided with a No. 3 motor 32 and a No. 1 slide rail. The No. 1 slide rail is provided with a No. 2 slider. The No. 2 slider is provided with a washboard 33 for kneading the rubber member. The output shaft end of the No. 3 motor 32 is provided with a rotating block. The rotating block is eccentrically provided with a crank. The crank is connected to the washboard 33 to drive the washboard 33 to move along the No. 1 guide rail. The bottom of the No. 1 mounting frame is provided with a vertical guide rail and a vertical cylinder. The vertical cylinder drives the No. 1 mounting frame to move on the vertical guide rail.

[0076] The moving assembly includes a No. 2 mounting frame, which is provided with a No. 2 guide rail, a No. 3 slider, and a No. 4 cylinder on the No. 3 slider. The No. 4 cylinder is used to drive the No. 3 slider to move along the No. 2 guide rail. The No. 3 slider is provided with a drawer plate 34, and the drawer plate 34 is provided with a No. 1 fixing block 35 for limiting the rubber part.

[0077] In the above embodiment, when the rubber pieces are arranged on conveyor No. 3 4, the moving mechanism 14 moves the rubber pieces on conveyor No. 3 4 to the first fixed block 35 on the moving assembly. The rubber pieces are now encased in the first fixed block 35. The fourth cylinder drives the third slider to move, causing the first fixed block 35 to move the rubber pieces toward the detection assembly.

[0078] When the rubber piece reaches the inspection assembly, the inspection assembly's third motor 32 starts, causing the rotating block to rotate, which in turn causes the crank to move the washboards 33. The two washboards 33 rub the rubber piece, causing it to deform. The inspection machine 31 then checks the front of the rubber piece for deep cracks.

[0079] As a further solution of the present invention, the No. 1 ring groove detection mechanism 12 includes a No. 3 mounting frame, on which a visual detector 36 and a No. 4 motor are provided. The output shaft end of the No. 4 motor is provided with a No. 2 fixing block 37 for limiting the rubber part.

[0080] In the above embodiment, when the rubber member is moved to the No. 2 fixed block 37 by the moving mechanism 14, the visual detector 36 detects the annular groove on the side wall of the rubber member. During the detection process, the No. 4 motor drives the No. 2 fixed block 37 to rotate, so that the annular groove is fully detected.

[0081] As a further solution of the present invention, the No. 2 ring groove detection mechanism 13 includes a No. 4 mounting frame, on which a visual detector 38, a visual detector 39 and a No. 5 motor are provided. The detection directions of the visual detector 38 and the visual detector 39 are opposite and are on the same straight line. The visual detector 38 and the visual detector 39 are arranged at an angle, and the output shaft end of the No. 5 motor is provided with a No. 3 fixed block 40 for limiting the rubber part.

[0082] In the above embodiment, the moving mechanism 14 includes a No. 3 guide rail 41, on which a No. 1 grabbing assembly, a No. 2 grabbing assembly, a No. 3 grabbing assembly, a No. 4 grabbing assembly and a No. 5 grabbing assembly are provided;

[0083] The first grabbing assembly includes a lifting arm 42 and a grabbing arm 43, which are used to transport the rubber parts on the third conveyor 4 to the first crack detection mechanism 11;

[0084] The second grabbing assembly, the third grabbing assembly, the fourth grabbing assembly and the fifth grabbing assembly all include a lifting arm 42 and a transverse moving plug-in. The transverse moving plug-in includes a transverse bracket, a transverse cylinder, a transverse guide rail and a transverse slider 44. The bottom of the transverse slider 44 is provided with a grabbing arm 43.

[0085] Among them, a vertical bracket 45 is provided at the bottom of the horizontal slider of the fourth grabbing assembly, a horizontal motor 46 is provided on the vertical bracket 45, and a grabbing arm 43 is provided at the output shaft end of the horizontal motor 46;

[0086] The moving mechanism 14 also includes four waste material guide chutes 47, which are respectively arranged at the two crack detection mechanisms 11, the ring groove detection mechanism 12 and the appearance detection mechanism 13, and also includes a qualified product guide chute 48, which is arranged on the frame 1 for collecting qualified products.

[0087] In the above embodiment, the third guide rail 41 can be driven by a cylinder to move along its length during operation, which is a prior art.

[0088] Among them, the lifting arm 42 in the No. 1 grabbing assembly can drive the grabbing arm 43 to rise and fall, so that the grabbing arm 43 moves to the rubber part on the No. 3 conveyor 4 and clamps the rubber part. As the lifting arm 42 and the No. 3 guide rail 41 move, the rubber part at the No. 3 conveyor 4 is moved to the No. 1 crack detection mechanism 11.

[0089] The No. 2 grabbing assembly, the No. 3 grabbing assembly, the No. 4 grabbing assembly and the No. 5 grabbing assembly are equipped with a transverse moving plug-in relative to the No. 1 grabbing assembly, so that the grabbing arms 43 on the No. 2 grabbing assembly, the No. 3 grabbing assembly, the No. 4 grabbing assembly and the No. 5 grabbing assembly can move transversely. During the transverse movement, the corresponding transverse cylinder drives the transverse slider 44 to move on the transverse guide rail.

[0090] Among them, the No. 4 grabbing component is equipped with a vertical bracket 45 and a horizontal motor 46 relative to the No. 2 grabbing component, the No. 3 grabbing component and the No. 5 grabbing component, so that the grabbing arm 43 on the No. 4 grabbing component can grab horizontally and be flipped, so that the rubber part at the No. 1 ring groove detection mechanism 12 can be flipped and moved to the No. 2 ring groove detection mechanism 13.

[0091] Among them, the No. 5 grabbing component grabs the qualified products and puts them into the qualified product guide chute 48, and the rest are grabbed by the No. 2 grabbing component, the No. 3 grabbing component, and the No. 4 grabbing component and put into the waste guide chute 47 for recycling.

[0092] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
