Description

Technical Field

[0001] This invention relates to the field of testing rubber ring products, and in particular to an automatic tensile testing device for ring products. Background Technology

[0002] During the production of rubber ring products, routine physical performance testing, specialized performance testing, and appearance quality testing are required for the finished products. Appearance quality testing mainly includes surface inspection (checking for defects such as obvious scars, bubbles, scratches, and impurities). Currently, surface inspection is generally carried out manually, but manual inspection is inefficient and prone to omissions. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides an automatic tensile testing device for ring products, which has the advantage of high testing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic tensile testing device for ring products includes:

[0006] frame;

[0007] The testing device, installed inside the frame, includes a top surface testing mechanism, an outer surface testing mechanism, a bottom surface testing mechanism, and an inner surface testing mechanism. The top surface testing mechanism, the outer surface testing mechanism, the bottom surface testing mechanism, and the inner surface testing mechanism are circumferentially distributed and respectively test the top surface, outer surface, bottom surface, and inner surface of the ring product.

[0008] A circular product inspection and conveying device, disposed within the frame, includes a rotating conveying mechanism and a circular product rotation drive mechanism. The rotating conveying mechanism includes at least four fixtures and an intermittent drive assembly. The fixtures are used to install and stretch the circular products. The intermittent drive assembly drives the fixtures through the top surface inspection mechanism, the outer surface inspection mechanism, the bottom surface inspection mechanism, and the inner surface inspection mechanism. The circular product rotation drive mechanism is used to simultaneously drive the circular products on the four fixtures corresponding to the inspection device to rotate.

[0009] By adopting the above technical solution, a ring product is installed on the tooling. The tooling stretches the ring product, and then the intermittent drive component drives the tooling and the ring product on it to sequentially inspect the top surface, outer surface, bottom surface, and inner surface of the ring product. This completes the inspection of the top, outer, bottom, and inner surfaces of the ring product. The four surfaces are inspected separately, which greatly improves the quality of the inspection. In addition, the ring product is in a stretched state during the inspection, which makes the defects larger and easier to inspect, thus improving the inspection efficiency and quality. Furthermore, the simultaneous inspection of four ring products greatly improves the inspection efficiency.

[0010] Optionally, the rotary conveying mechanism further includes a rotary conveying disk; the tooling includes an active drive wheel, a driven drive wheel, a driven moving seat, and a translation drive; the driven drive wheel is disposed on the driven moving seat and has a horizontally rotatable rotating support; the translation drive is used to drive the driven moving seat away from or towards the active drive wheel; the active drive wheel has an active drive portion rotatably connected to the rotary conveying disk; the active drive portion and the rotating support portion are used to support the ring product; the ring product rotation drive mechanism is used to simultaneously drive the active drive portions on the four toolings corresponding to the detection device to rotate.

[0011] By adopting the above technical solution, when the driven drive wheel and the active drive wheel approach each other, the ring product is simultaneously fitted onto the rotating support part of the driven drive wheel and the active drive wheel. At this time, the ring product is easy to install and operate. Then, the translation drive component drives the driven moving seat and its driven drive wheel away from the active drive wheel, which stretches the ring product. The whole process is time-saving and labor-saving. In addition, the self-rotation drive mechanism of the ring product is used to drive the active drive wheels on the four toolings corresponding to the detection device to rotate, which makes the working cycle easier to control.

[0012] Optionally, the active drive unit has an annular active drive ring; the active drive wheel unit further includes a main retainer; the main retainer is fixed on the rotating conveyor disk; the main retainer has an upper main support ring and a lower main support ring; the upper main support ring and the lower main support ring are distributed vertically and the active drive ring is located between the upper main support ring and the lower main support ring; a main ring groove for the annular product to enter is formed between the upper main support ring, the active drive ring, and the lower main support ring;

[0013] The rotating support portion is a driven portion; the driven portion has an annular driven ring; the driven wheel portion further includes a secondary retainer; the secondary retainer is fixed on the driven moving seat; the secondary retainer has an upper secondary support ring and a lower secondary support ring; the upper secondary support ring and the lower secondary support ring are distributed vertically and the driven ring is located between the upper secondary support ring and the lower secondary support ring; a secondary ring groove for the annular product to enter is formed between the upper secondary support ring, the driven ring, and the lower secondary support ring.

[0014] By adopting the above technical solution, it is possible to adapt to softer ring products. The specific reasons are as follows: When the ring product is soft, it will roll upwards and flip over during its rotation, which is not conducive to subsequent inspection. The above technical solution, by setting a main upper support ring and a secondary upper support ring on the upper side of the ring product, and a main lower support ring and a secondary lower support ring on the lower side, can prevent the ring product from rolling upwards or downwards and avoid the flipping phenomenon.

[0015] Optionally, both the outer peripheral surface of the active drive ring and the outer peripheral surface of the driven drive ring are convex in the middle, resembling a waist drum.

[0016] By adopting the above technical solution, both the outer peripheral surfaces of the active drive ring and the driven drive ring are convex in the middle, forming a drum-shaped surface. This makes the ring product fitted between the active drive ring and the driven drive ring convex in the middle, thereby increasing the overall tension and reducing the possibility of the ring product moving upward or downward. At the same time, if there are defects on the surface of the ring product in the tensioned state, they will be more obvious, which is beneficial for subsequent inspection.

[0017] Optionally, the circular product rotation drive mechanism includes four rotation drive shafts and a circular product rotation drive assembly for simultaneously driving the four rotation drive shafts; the rotation drive shafts and the active drive wheel are connected by a magnetic wheel.

[0018] By adopting the above technical solution, since the self-rotating drive shaft and the active drive wheel are connected by a magnetic wheel, the connection can realize the transmission of force when the self-rotating drive shaft and the active drive wheel are coaxial, and can also be separated immediately when the rotating conveyor disk rotates, so as not to affect the switching of workstations.

[0019] Optionally, the circular product inspection and conveying device further includes a contacting mechanism; the contacting mechanism includes a contacting lifting plate that is lifted and lowered on the upper side of the rotating conveying mechanism, a contacting lifting drive assembly for driving the contacting lifting plate to rise and fall, and four contacting components disposed on the contacting lifting plate; the four contacting components correspond one-to-one with the four toolings of the inspection device; the contacting components are used to contact the circular products on the tooling.

[0020] By adopting the above technical solution, before the ring product is inspected, the abutment lifting drive component drives the abutment lifting plate to descend, and the abutment component on it abuts against the ring product installed on the corresponding tooling. In this way, when the ring product rotates, the abutment component can stabilize the ring product, thereby improving the accuracy of the inspection. After the ring product is inspected, the abutment lifting drive component drives the abutment lifting plate to rise back to its original position, thereby avoiding interference with the tooling during the workstation switching process.

[0021] Optionally, the abutting component includes a radial abutting drive and an abutting block; the radial abutting drive is used to drive the abutting block radially away from or towards the annular product.

[0022] By adopting the above technical solution, when it is necessary to abut against the circular product, the radial abutment drive component drives the abutment block to move radially to abut against the circular product; when it is necessary to detach from the circular product, the radial abutment drive component drives the abutment block to move radially to detach from the circular product. In this way, the possibility of the abutment block scratching the circular product is reduced during the lifting and lowering process of the abutment component.

[0023] Optionally, the frame is provided with a feeding position; an automatic feeding device is provided at the feeding position; the automatic feeding device includes a feeding gripper and a horizontal feeding mechanism; the horizontal feeding mechanism drives the feeding gripper to move horizontally; the feeding gripper is used for the ring product on the tooling at the feeding position.

[0024] By adopting the above technical solution, the existence of the automatic feeding device eliminates the need for manual feeding, greatly improving the detection efficiency and saving time and effort. At the same time, the horizontal feeding mechanism drives the feeding gripper to move horizontally, which can avoid the tooling during station switching.

[0025] Optionally, the unloading gripper includes:

[0026] The feeding gripper is used to grasp circular ring products;

[0027] A horizontal rotation component is used to drive the unloading jaws to rotate horizontally;

[0028] A translation drive component is used to drive the horizontal rotation component to translate.

[0029] A lifting drive assembly is used to drive the translation drive assembly to lift and lower.

[0030] By adopting the above technical solution, the lifting and lowering action of the lifting drive component can make the ring product vertically detach from the tooling, reducing the possibility of the ring product getting caught on the tooling during subsequent horizontal movement; the translation drive component can correct the relative position of the unloading chuck and the ring product on the tooling within a certain range; the horizontal rotation component can make the gripping position of the unloading chuck face the ring product on the tooling, thereby improving the stability of unloading and gripping, and can also avoid the possibility of the ring product getting caught on the tooling to a certain extent.

[0031] Optionally, it may also include a finished product sorting device; the finished product sorting device includes several finished product collection mechanisms; the inlets of all the finished product collection mechanisms are distributed along the horizontal movement direction of the unloading gripper.

[0032] By adopting the above technical solution, the tested circular products can be classified, which is beneficial for subsequent different processing. Attached Figure Description

[0059] 90. Circular ring products. Detailed Implementation

[0060] The following is in conjunction with the appendix Figures 1-17 The present invention will be described in further detail below.

[0061] Example 1: An automatic tensile testing device for ring products is disclosed, used to test rubber ring products, hereinafter referred to as ring products 90 for ease of description; Reference Figure 1 and Figure 2 The system includes a frame 10, a circular product inspection and conveying device 40, and an inspection device 60. The frame 10 includes a frame 11, an upper support plate 13, and a lower support plate 14. The upper support plate 13 and the lower support plate 14 are distributed vertically and fixed within the frame 11. Several protective doors 12 are installed on the frame 11. The frame 10 has a normally open feed port 100. To control the light entering the feed port 100, light shields 15 are fixed on both sides of the feed port 100 to prevent external light from affecting the inspection. The circular product inspection and conveying device 40 and the inspection device 60 are both located within the frame 10. The circular product inspection and conveying device 40 conveys the circular product 90, and the inspection device 60 is used to inspect the circular product 90.

[0062] refer to Figure 2 and Figure 9 The circular product inspection and conveying device 40 includes a rotary conveying mechanism 20 and a circular product self-rotation drive mechanism 50; Reference Figure 3 , Figure 4 and Figure 7The rotating conveying mechanism 20 includes a rotating conveying disk 22 rotatably connected to the upper end surface of the upper support plate 13, four tooling fixtures 23 evenly fixed to the upper end surface of the rotating conveying disk 22, and an intermittent drive assembly for driving the rotating conveying disk 22 to rotate intermittently; the intermittent rotation angle of the rotating conveying disk 22 is 90°. The intermittent drive assembly can be an intermittent drive servo motor 21, and the rotating conveying disk 22 is fixed to the output shaft of the intermittent drive servo motor 21.

[0063] refer to Figure 8 and Figure 9The tooling 23 includes an active drive wheel 231, a driven drive wheel 236, a driven moving seat 234, and a translation drive component 232. The active drive wheel 231 is rotatably connected to the rotating conveyor disk 22. The active drive wheel 231 includes a first active drive wheel shaft 2311, an active drive wheel body 2312, and a first magnetic drive wheel 2313. The first active drive wheel shaft 2311 passes perpendicularly through the rotating conveyor disk 22 and is rotatably connected to the rotating conveyor disk 22 via a bearing seat. The first magnetic drive wheel 2313 is coaxially fixed to the lower end of the first active drive wheel shaft 2311. The active drive wheel body 2312... 312 is coaxially fixed to the upper end of the first active drive wheel shaft 2311, at which time the active drive wheel part 231 serves as the active drive part; the active drive wheel body 2312 is composed of two coaxial disks, with the diameter of the upper disk being smaller than that of the lower disk. The translation drive component 232 is fixed on the rotating transmission disk 22. The translation drive component 232 can be a linear drive component such as a cylinder or an electric cylinder. Here, we will describe the translation drive component 232 as a cylinder. A connecting seat 233 is fixed on the piston rod of the translation drive component 232; the connecting seat 233 is fixedly connected to the driven moving seat 234; in order to improve the driven moving seat 234 To ensure the stability of movement of the 34, a first linear guide rail 235 is provided between the driven moving seat 234 and the upper end face of the rotating transmission disk 22; the direction of the first linear guide rail 235 is the same as the extension and retraction direction of the translation drive member 232; the driven drive wheel part 236 includes a first driven drive wheel shaft 2361 and a driven drive wheel body 2362; the first driven drive wheel shaft 2361 is fixed on the driven moving seat 234; the driven drive wheel body 2362 is rotatably connected to the upper end of the first driven drive wheel shaft 2361 through a bearing, and the driven drive wheel body 2362 acts as a rotation support part. The structure is the same as that of the active drive wheel body 2312 and both are on the same horizontal plane. During operation, the upper disks of the active drive wheel body 2312 and the driven drive wheel body 2362 are used to mount the ring product 90. In the initial state, the active drive wheel part 231 and the driven drive wheel part 236 are close to each other, which makes it easy for the ring product 90 to be fitted onto the upper disks of the active drive wheel body 2312 and the driven drive wheel body 2362. Then, the translation drive 232 is activated, causing the driven drive wheel part 236 to move away from the active drive wheel part 231, thereby stretching the ring product 90.

[0064] In other embodiments, reference is made to Figure 9 and Figure 10The active drive wheel section 231 includes an active drive section and a main retainer; the active drive section includes a second active drive wheel shaft 2314 and an active drive seat 2317 coaxially fixed to the upper end of the second active drive wheel shaft 2314; the second active drive wheel shaft 2314 passes vertically through the rotating transmission disk 22 and is rotatably connected to the rotating transmission disk 22 through a bearing seat; a first magnetic drive wheel 2313 is coaxially fixed to the lower end of the second active drive wheel shaft 2314; an annular active drive ring 23171 is formed on the upper end surface of the active drive seat 2317; the main retainer includes an L-shaped main connecting block 2315 fixed to the bearing seat, an annular main lower support ring 2316 fixed to the main connecting block 2315, and a main lower support ring 2316 fixed to the bearing seat. The main lower support ring 2316 has a main upper support seat 2318; the main connecting block 2315 is fixed in position relative to the rotating conveyor disk 22; the main lower support ring 2316 and the main upper support seat 2318 are coaxially sleeved and connected to the active drive seat 2317 through bearings; a coaxially arranged annular main upper support ring 23181 is formed on the outer periphery of the main upper support seat 2318, and the main upper support ring 23181 is located on the upper side of the main lower support ring 2316, and the active drive ring 23171 is located between the main upper support ring 23181 and the main lower support ring 2316; a main ring groove 2310 is formed between the main upper support ring 23181, the active drive ring 23171 and the main lower support ring 2316 for the annular product 90 to enter. Driven drive wheel section 236 includes a secondary retainer and a rotary support section; the secondary retainer includes a second driven drive wheel shaft 2363 fixed to the driven moving seat 234, a secondary upper support seat 2364 coaxially fixed to the second driven drive wheel shaft 2363, and a secondary lower support ring 2365 coaxially fixed to the secondary upper support seat 2364; the rotary support section is an annular driven drive section 2366; an annular driven drive ring 23661 is formed at the upper end of the driven drive section 2366; driven drive section 2366... 366 is rotatably connected to the upper auxiliary support seat 2364 via a bearing; an annular upper auxiliary support ring 23641 is formed on the outer periphery of the upper auxiliary support seat 2364; the upper auxiliary support ring 23641 is located above the lower auxiliary support ring 2365, and the driven ring 23661 is located between the upper auxiliary support ring 23641 and the lower auxiliary support ring 2365; a sub-annular groove 2360 for the annular product to enter is formed between the upper auxiliary support ring 23641, the driven ring 23661 and the lower auxiliary support ring 2365. During operation, the two ends of the circular product 90 are located in the main ring groove 2310 and the secondary ring groove 2360, respectively. Due to the obstruction of the upper main support ring 23181 and the secondary upper support ring 23641 on the upper side, the circular product 90 will not roll upward and flip over during its rotation. Due to the obstruction of the lower main support ring 2316 and the secondary lower support ring 2365 on the lower side, the circular product 90 will not roll upward and flip over during its rotation.To further reduce the possibility of flipping, both the outer peripheral surfaces of the active drive ring 23171 and the driven drive ring 23661 are convex in the middle, forming a waist-shaped drum. That is, the curves of the outer peripheral surfaces of the active drive ring 23171 and the driven drive ring 23661 in cross-section are convex in the middle. Additionally, to reduce obstruction to the inlet and outlet of the circular product 90, the outer peripheral surfaces of the upper ends of the main lower support ring 2316 and the secondary lower support ring 2365 are formed into conical surfaces that are smaller at the top and larger at the bottom.

[0065] refer to Figure 12 and Figure 13The circular product rotation drive mechanism 50 includes four rotation drive shafts 52 and a circular product rotation drive assembly for simultaneously driving the four rotation drive shafts 52. Each rotation drive shaft 52 includes a rotation drive shaft body 521, a second magnetic transmission wheel 523 coaxially fixed to the upper end of the rotation drive shaft body 521, and a synchronous belt pulley 522 coaxially fixed to the lower end of the rotation drive shaft body 521. The rotation drive shaft body 521 vertically passes through the upper support plate 13 and is rotatably connected to the upper support plate 13 via a bearing seat. A lower bracket 131 is fixed to the lower end face of the upper support plate 13. The circular product rotation drive assembly includes a circular product rotation drive servo motor 51 and a synchronous belt 53. The circular product rotation drive servo motor 51 is fixed to the lower bracket 131 and connected to one of the rotation drive shaft bodies 521 via a coupling. The lower end is connected; the synchronous belt 53 is sleeved on four synchronous pulleys 522; in order to control the tension of the synchronous belt 53, a number of synchronous belt tensioning components 54 are fixed on the lower end surface of the upper support plate 13; the synchronous belt tensioning component 54 includes a synchronous belt tensioning seat 541 and a synchronous belt tensioning wheel 542 rotatably connected to the synchronous belt tensioning seat 541; the synchronous belt tensioning wheel 542 abuts against the outer surface of the synchronous belt 53; the synchronous belt tensioning seat 541 is connected to the lower end surface of the upper support plate 13 by a pair of bolts, and a pair of parallel elongated holes are formed on the synchronous belt tensioning seat 541 that cooperate with the screws of the bolts and the direction of the elongated holes points to the synchronous belt 53. In this way, the relative position of the synchronous belt tensioning seat 541 and the synchronous belt 53 can be adjusted by loosening the bolts, that is, the relative position of the synchronous belt tensioning wheel 542 and the synchronous belt 53 can be adjusted. During operation, the servo motor 51 driving the rotation of the circular product starts, and the synchronous pulley 522 of the connected rotation drive shaft 52 drives the synchronous belt 53 to move, thereby driving the other three rotation drive shafts 52 to rotate synchronously through the other three synchronous pulleys 522. When the first magnetic drive wheel 2313 of the corresponding tooling 23's active drive wheel 231 is coaxial with the second magnetic drive wheel 523 of the corresponding rotation drive shaft 52, the rotation of the rotation drive shaft 52 can drive the active drive wheel 231 to rotate, thereby driving the circular product 90 to rotate. When the rotating conveyor 22 drives the tooling 23 to rotate, the second magnetic drive wheel 523 and the first magnetic drive wheel 2313 separate. Since the force required to drive the circular product 90 to rotate is not too large, the magnetic wheel connection method of the second magnetic drive wheel 523 and the first magnetic drive wheel 2313 is more suitable, and it is also convenient to connect and disconnect.

[0066] refer to Figure 3The testing device 60 includes a top surface testing mechanism 61, an outer surface testing mechanism 62, a bottom surface testing mechanism 63, and an inner surface testing mechanism 64. All four mechanisms are fixed to the upper support plate 13 and correspond one-to-one with the tooling 23. They are circumferentially distributed and respectively test the top, outer, bottom, and inner surfaces of the annular product 90. The outer surface testing mechanism 62 and the bottom surface testing mechanism 63 are located on the upper end surface of the upper support plate 13. The system includes a detection bracket and a pair of cameras fixed to the detection bracket. The direction of the cameras is adjustable, specifically by using an adjustment groove with an arcuate groove on the detection bracket. The cameras are fixed to the detection bracket by bolts passing through the adjustment groove. The top detection mechanism 61 includes a detection bracket fixed to the upper end surface of the upper support plate 13 and a camera fixed to the detection bracket. The bottom detection mechanism 63 includes a detection bracket fixed to the lower end surface of the upper support plate 13 and a camera fixed to the detection bracket. The upper support plate 13 has detection through holes 130 formed to cooperate with the cameras of the bottom detection mechanism 63. To make the image clearer, a supplementary lighting mechanism is provided on the upper support plate 13. The order of the top detection mechanism 61, the outer detection mechanism 62, the bottom detection mechanism 63, and the inner detection mechanism 64 can be changed.

[0067] During operation, the circular product rotation drive mechanism 50 drives the four circular products 90 on the tooling 23 to rotate one revolution simultaneously. During this process, the top surface inspection mechanism 61, the outer surface inspection mechanism 62, the bottom surface inspection mechanism 63, and the inner surface inspection mechanism 64 simultaneously inspect the corresponding surfaces of the four circular products 90. Then, the rotating conveyor 22 rotates 90°, and the circular product 90 reaches the next inspection mechanism for inspection of the corresponding surface. Based on the above principle, the four surfaces of the circular product 90 are inspected. Since the four surfaces are inspected separately, the inspection quality is high. The simultaneous inspection of multiple circular products 90 results in high inspection efficiency.

[0068] Example 2: The difference between Example 2 and Example 1 is as follows: (Refer to...) Figure 2 , Figures 4-6 To improve the rotational stability of the ring product 90 during the testing process and thus improve the testing quality, the ring product testing and conveying device 40 also includes a backing mechanism 30. The backing mechanism 30 includes a backing bracket 31 fixed to the upper surface of the lower support plate 14, a backing lifting plate 37 that is lifted and lowered on the upper side of the rotating conveying mechanism 20, a backing lifting drive assembly for driving the backing lifting plate 37 to rise and fall, and four backing components 38 disposed on the backing lifting plate 37. The four backing components 38 correspond one-to-one with the four tooling 23s of the testing device 60. The backing components 38 are used to back the ring product 90 on the tooling 23.

[0069] refer to Figures 4-6 The lifting drive assembly includes a lifting spindle 36 and a lifting drive component. The lifting drive component drives the lifting spindle 36 to move up and down along its axial direction. The lifting drive component includes a geared motor 32 fixed on a support bracket 31, a drive sprocket 321 coaxially fixed on the output shaft of the geared motor 32, a lifting drive driven shaft 33 rotatably connected to the support bracket 31, a driven sprocket 331 coaxially fixed on the lifting drive driven shaft 33, a chain 39 connecting the drive sprocket 321 and the driven sprocket 331, and a lifting drive cam 34 coaxially fixed on the lifting drive driven shaft 33. A vertical guide sleeve 35 is vertically inserted and fixed on the geared motor 32. The lifting spindle 36 vertically passes through the vertical guide sleeve 35. The lower end of the lifting spindle 36 abuts against the working surface of the lifting drive cam 34, and the upper end is fixedly connected to the lifting plate 37. To reduce friction, a roller is connected to the lower end of the lifting spindle 36. The roller abuts against the upper end of the working surface of the lifting drive cam 34. To prevent the lifting spindle 36 from rotating, a second linear guide rail 361 is connected between the lower end of the lifting spindle 36 and the abutment bracket 31; the direction of the second linear guide rail 361 is parallel to the axis of the lifting spindle 36. To control the tension of the chain 39, a tension sprocket assembly 391 is provided on the abutment bracket 31. The tension sprocket assembly 391 is existing technology and will not be described in detail here.

[0070] refer to Figures 4-7 To reduce the floor space, the intermittent drive servo motor 21 can be replaced with a hollow rotary cylinder. The hollow rotary cylinder is fitted onto the vertical guide sleeve 35, and a circular connecting ring 211 is fixed to the top of the hollow rotary cylinder. The connecting ring 211 is fixedly connected to the upper end of the vertical guide sleeve 35. Several connecting brackets 212 are fixed on the rotating part of the hollow rotary cylinder. The rotating transmission disk 22 is fitted onto the vertical guide sleeve 35 and is fixedly connected to the housing of the geared motor 32 through a bearing seat. The connecting brackets 212 are connected to the rotating transmission disk 22.

[0071] refer to Figure 6The abutment component 38 includes a radial abutment drive 381 and an abutment block 384. The radial abutment drive 381 is used to drive the abutment block 384 radially away from or towards the annular product 90. The radial abutment drive 381 is a linear drive component such as a cylinder or an electric cylinder. Taking a cylinder as an example, a support plate 382 is fixed on the piston rod of the radial abutment drive 381. A pair of vertically arranged vertical connecting rods 383 are fixed on the support plate 382. The abutment block 384 is fixed to the bottom of the pair of vertical connecting rods 383. To reduce the possibility of the abutment block 384 scratching the annular product 90, the abutment block 384 is elongated and made of nylon with a smooth surface. During operation, the abutment block 384 corresponding to the inner surface detection mechanism 64 abuts against the outer surface of the annular product 90, which is close to the axis of the rotating conveyor disk 22. This avoids obstructing the camera from capturing the inner surface of the annular product 90. The abutment blocks 384 corresponding to the top surface detection mechanism 61, the outer surface detection mechanism 62, and the bottom surface detection mechanism 63 all abut against the inner surface of the annular product 90. To reduce obstruction to the camera, a U-shaped notch is formed on the support plate 382, ​​and the U-shaped notch is located between a pair of vertical connecting rods 383.

[0072] Example 3: The difference between Example 3 and Example 1 is as follows: (Refer to...) Figures 14-15 To facilitate loading and unloading, loading and unloading positions are added within the frame 10, further improving inspection efficiency. The loading position faces the feed inlet 100 and is used to mount the ring product 90 onto the tooling 23. The unloading position is adjacent to the loading position, and the number of tooling 23s on the rotating conveyor 22 increases from four to six, while the intermittent rotation angle of the rotating conveyor 22 changes from 90° to 60°. An automatic unloading device 70 is installed at the unloading position, comprising an unloading support frame 71, an unloading gripper 73, and a horizontal unloading mechanism 72. The unloading support frame 71 is fixed to the upper surface of the upper support plate 13; the horizontal unloading mechanism 72 is fixed to the unloading support frame 71; the horizontal unloading mechanism 72 drives the unloading gripper 73 to move horizontally; the unloading gripper 73 is used for the ring product 90 on the tooling 23 at the unloading position. The horizontal unloading mechanism 72 uses an electric slide table, but linear drive components such as electric cylinders or pneumatic cylinders can also be used.

[0073] refer to Figure 15 and Figure 16The unloading gripper 73 includes an unloading claw for gripping circular products, a horizontal rotation assembly 76 for driving the unloading claw to rotate horizontally, a translation drive assembly 75 for driving the horizontal rotation assembly 76 to translate, and a lifting drive assembly 74 for driving the translation drive assembly 75 to lift. The specific structure is as follows: The lifting drive assembly 74 uses a vertically arranged electric cylinder and is fixed to the first slide 721 of the horizontal unloading mechanism 72. A lifting mounting bracket 741 is fixed to the lower end of the piston rod of the lifting drive assembly 74. The translation drive assembly 75 uses a horizontally arranged electric slide and is fixed to the lower end face of the lifting mounting bracket 741. The horizontal rotation assembly 76 uses a rotary cylinder and is fixed to the lower end face of the second slide 751 of the translation drive assembly 75. The unloading claw includes a claw cylinder 77 and a fixing block 78. The claw cylinder 77 is fixed to the horizontal rotation assembly. On the rotating shaft of 76, the two fingers of the gripper cylinder 77 are located on both sides of the housing, and movable grippers 771 are fixed on the fingers. The fixed gripper 78 is in the shape of a "U" with its opening facing downwards, and its horizontal part is fixed to the lower end face of the housing of the gripper cylinder 77. A pair of vertical parts cooperate with the corresponding movable grippers 771 to achieve clamping. During operation, the pair of vertical parts of the fixed gripper 78 enter the interior of the stretched ring product 90, and the pair of movable grippers 771 are located on the outside of the stretched ring product 90. Thus, when the gripper cylinder 77 drives the pair of movable grippers 771 to move closer to each other, they clamp with the vertical parts of the fixed gripper 78 on the corresponding side. In other embodiments, the lifting drive assembly 74 and the translation drive assembly 75 can also be other linear drive components such as electric cylinders, electric slides, and pneumatic cylinders.

[0074] In other embodiments, the frame 10 may only have a feeding position and no feeding position, and the first inspection station may be used as a feeding position.

[0075] In other embodiments, in order to accurately control the start-up timing of the automatic feeding device 70, a feeding sensor is provided at the feeding position to monitor the tooling 23. When the tooling 23 is in place, the feeding sensor controls the automatic feeding device 70 to start. The feeding sensor can be a photoelectric switch. For example, six transmitters can be installed on the rotating conveyor plate 22, with each transmitter corresponding to one of the tooling 23. A receiver is installed at the feeding position. When the receiver receives the light beam emitted by the transmitter, the automatic feeding device 70 starts working.

[0076] In other embodiments, considering that the circular ring product 90 has multiple possible outcomes after inspection: pass, fail, or require re-inspection, refer to Figure 14 The frame 10 is also equipped with a finished product sorting device 80, which is used to sort the circular products 90 in the above three situations.

[0077] refer to Figure 14 and Figure 17 The finished product sorting device 80 includes a qualified finished product collection mechanism 83, an unqualified finished product collection mechanism 82, and a finished product collection mechanism 81 to be inspected. The qualified finished product collection mechanism 83 is used to collect qualified finished products, the unqualified finished product collection mechanism 82 is used to collect unqualified finished products, and the finished product collection mechanism 81 to be inspected is used to collect finished products that need to be inspected again.

[0078] refer to Figure 14 and Figure 17 The qualified finished product collection mechanism 83 includes a qualified finished product hopper 831 and a qualified finished product collection box 832; the unqualified finished product collection mechanism 82 includes an unqualified finished product hopper 821 and an unqualified finished product belt conveyor 822; and the finished product collection mechanism 81 includes a finished product hopper 811 and a finished product belt conveyor 812. The qualified finished product hopper 831, unqualified finished product hopper 821, and finished product hopper 811 are sequentially distributed along the parallel direction of the horizontal feeding mechanism 72, with the qualified finished product hopper 831 closer to the tooling 23 and the finished product hopper 811 further away from the tooling 23. The stroke of the corresponding side of the horizontal feeding mechanism 72 is adjustable to accommodate different stopping positions. The qualified finished product hopper 831, unqualified finished product hopper 821, and finished product hopper 811 pass vertically through... The upper support plate 13 has its inlet located on the upper side of the upper support plate 13 and its outlet located on the lower side of the upper support plate 13. The belt conveyor 812 for finished products to be inspected and the belt conveyor 822 for unqualified products are fixed on the lower end surface of the upper support plate 13 and their conveying directions are perpendicular to each other. The outlet of the hopper 811 for finished products to be inspected is located directly above the inlet of the belt conveyor 812 for finished products to be inspected, and the outlet of the hopper 821 for unqualified products is located directly above the inlet of the belt conveyor 822 for unqualified products. In this way, the outlets of the two products will be far apart from each other, which can prevent operators from confusing the two types of annular products 90. The qualified finished product collection box 832 is fixed on the upper end surface of the lower support plate 14 and is located directly below the outlet of the qualified finished product hopper 831.

[0079] In other embodiments, an automatic feeding device can be provided at the feeding position, and the structure of the automatic feeding device can be based on the automatic unloading device 70.

[0080] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
