[0028] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1 As shown, this embodiment provides a bearing detection device, which is very suitable for bearing detection with an outer diameter between 12-30 mm. The bearing detection device includes a frame 100 provided with an assembly line, a control system (not shown), a material feeding mechanism 60 connected to the control system, and a first end face imaging mechanism 10, a flipping mechanism 20, a second end face imaging mechanism 30, an inner wall imaging mechanism 40 and a lateral appearance / size imaging mechanism 50 connected to the control system and arranged in sequence along the assembly line; specifically, a carrier 101 is provided on the frame 100, and the workstations corresponding to the first end face imaging mechanism 10, the second end face imaging mechanism 20, the inner wall imaging mechanism 40 and the lateral appearance / size imaging mechanism 50 are all located on the carrier, and the workstation corresponding to the flipping mechanism 20 is located on the flipping plate of the flipping mechanism 20.

[0030] The first end face imaging mechanism 10 is used to capture the first end face image of the bearing 1, the flipping mechanism 20 is used to flip the bearing 1 180°, the second end face imaging mechanism 30 is used to capture the second end face image of the bearing 1, the inner wall imaging mechanism 40 is used to capture the inner wall image of the bearing 1, and the lateral appearance / size imaging mechanism 50 is used to capture the outer wall image or lateral projection image of the bearing 1; the material transfer mechanism 60 is used to transfer the bearing 1 from the previous workstation to the next workstation; the control system is used to control the operation of each mechanism and process the collected image information.

[0031] Specifically, the workstations include: a first workstation at the feeding end, a second workstation corresponding to the first end surface imaging mechanism 10, a third workstation located on the flip plate of the flip mechanism 20, a fourth workstation corresponding to the second end surface imaging mechanism 30, a fifth workstation corresponding to the inner wall imaging mechanism 40, a sixth workstation corresponding to the lateral appearance / size imaging mechanism 50, a defective product rejection workstation, and a qualified product output workstation. Among them, a rejection mechanism (not shown) is provided on the defective product rejection workstation to reject defective products. Of course, the defective product rejection operation may not be provided on the assembly line of the equipment.

[0032] During the inspection, the bearing 1 enters the first station and is driven to move to the second station by the material-dispensing mechanism 60; at the beginning, the first end face of the bearing 1 is set upward, and the first end face imaging mechanism 10 collects the first end face image of the bearing 1 and outputs it to the control system for judgment; after the collection is completed, it moves to the third station, and the flipping mechanism 20 flips the bearing 180° so that its second end face faces upward, and after completion, it moves to the fourth station, and the second end face imaging mechanism 30 collects the second end face image of the bearing and outputs it to the control system for judgment; after the collection is completed, it moves to the fifth station, and the inner wall imaging mechanism 40 collects the inner wall image of the bearing and outputs it to the control system for judgment; after the collection is completed, it moves to the sixth station, and the lateral appearance / size imaging mechanism 50 collects the outer wall image and / or lateral projection image of the bearing, and outputs it to the control system for judgment; after the collection is completed, it moves to the unqualified product removal station to remove unqualified products, and the qualified products are transferred to the qualified product output station through the material-dispensing mechanism 60.

[0033] The device can automatically collect and judge the appearance of the end faces, inner wall and outer wall of the bearing 1; and collect and judge the lateral dimensions of the bearing 1. It realizes automated detection with high efficiency and good accuracy. At the same time, the device has good structural integration and small size.

[0034] Specifically, the pipeline is a straight pipeline, and the extension direction of the pipeline is defined as the X-axis direction.

[0035] For further information, please refer to Figure 3 As shown, in this embodiment, a feeding mechanism 70 is arranged at the front end of the first station, and the feeding mechanism 70 includes a Y-axis transmission assembly (defined as a first Y-axis transmission assembly 71), a Z-axis lifting assembly 72 connected to the first Y-axis transmission assembly 71, and a clamping assembly 73 connected to the Z-axis lifting assembly 72. The clamping assembly 73 is used to clamp the bearing 1. The Z-axis lifting assembly 72 can use a lifting cylinder to drive the clamping assembly 73 to rise and fall, and the first Y-axis transmission assembly 71 drives the bearing 1 on the clamping assembly 73 to transfer from the feed port to the first station. The feeding mechanism 70 has a simple structure and is easy to implement. Of course, in other embodiments, the bearing can also be directly conveyed to the first station by conveying with a conveyor belt.

[0036] For further information, please refer to Figure 2As shown, in this embodiment, the material-dispensing mechanism 60 includes: an X-axis transmission assembly 61, a Y-axis transmission assembly (defined as a second Y-axis transmission assembly 62), a clamping cylinder 63, a first clamping plate 64 and a second clamping plate 65, wherein the first clamping plate 64 and the second clamping plate 65 are connected to the clamping cylinder 63, and the first clamping plate 64 and the second clamping plate 65 form a plurality of pairs of clamping claws, which are driven to clamp or release by the clamping cylinder 63. The clamping cylinder 63 is arranged on the second Y-axis transmission assembly 62, and the second Y-axis transmission assembly 62 is arranged on the X-axis transmission assembly 61. When transferring the bearing, the second Y-axis transmission component 62 drives the clamping claw to extend into the workstation, the clamping cylinder 63 drives the clamping claw to grab the bearing 1, and the second Y-axis transmission component 62 drives the clamping claw to retract; then the X-axis transmission component 61 moves the distance of one workstation, so that the bearing 1 of the previous workstation corresponds to the next workstation, and then the second Y-axis transmission component 62 drives the clamping claw to extend into the workstation, the clamping cylinder 63 drives the clamping claw to release, put down the bearing 1, and finally the second Y-axis transmission component 62 drives the clamping claw to retract; the transfer of a product is completed. The structure is simple and the operation is easy.

[0037] Further, the first end surface imaging mechanism 10 and the second end surface imaging mechanism 30 are both used to collect end surface images. Therefore, the first end surface imaging mechanism 10 and the second end surface imaging mechanism 30 have the same structure. Figure 4 As shown, it includes a support column (defined as a first support column 11), a lifting drive (defined as a first lifting drive 12) arranged on the first support column 11, and an image collector (defined as a first image collector 13) and a top light source 14 connected to the first lifting drive 12, wherein the first image collector 13 and the top light source 14 are both located above the corresponding workstation. The top light source 14 is an annular light source, which illuminates the end face of the bearing 1, and the first image collector 13 collects images of the end face of the bearing 1. The structure is simple to implement.

[0038] More specifically, a parallel surface light source 80 is further provided below the workstation (i.e., the second workstation) corresponding to the first end surface imaging mechanism 10. Figure 1As shown, the light emitting surface of the parallel plane light source 80 faces upward, and a light-transmitting plate (defined as the first light-transmitting plate, not shown) is provided at the workstation corresponding to the first end face imaging mechanism 10, and a detachable light-shielding back plate (not shown) is provided between the first light-transmitting plate and the parallel plane light source 80. By adding the parallel plane light source 80 at the second workstation, the radial dimension detection can be added on the basis of the first end face imaging mechanism 10. The specific method is as follows: when radial dimension detection is required, the light-shielding back plate is removed, the parallel plane light source 80 is turned on, and the top light source 14 of the first end face imaging mechanism 10 is turned off. The parallel light is irradiated from bottom to top and collected by the first image collector 13 of the first end face imaging mechanism 10. In this way, a projected image can be obtained, and the dark shadow in the image is the radial image of the bearing 1. The outer diameter and inner diameter of the bearing 1 can be obtained by measuring the size of the dark shadow. The radial dimension measurement can be realized by adding the parallel plane light source 80 to the original end face imaging mechanism, which has a simple structure and good integration. Of course, the parallel surface light source 80 can also be arranged at the fourth station to cooperate with the second end surface imaging mechanism 30.

[0039] Furthermore, in this embodiment, the first light-transmitting plate is a glass plate, which has good light transmittance and is cheap. Of course, in other embodiments, other light-transmitting resin plates may also be used.

[0040] Continue to refer to Figures 5 to 7 As shown, the inner wall imaging mechanism 40 includes a surface light source 44 and an image acquisition component. A light-transmitting plate (defined as a second light-transmitting plate 102) is provided at the workstation corresponding to the inner wall imaging mechanism 40. The surface light source 44 is provided below the second light-transmitting plate 102, and the light-emitting surface is provided upward. The image acquisition component includes a supporting column (defined as a second supporting column 41), a lifting drive (defined as a second lifting drive) and an image collector (defined as a second image collector 43). The second lifting drive is provided on the supporting column 41, the second image collector 43 is located above the second light-transmitting plate 102, and is fixed on the second lifting drive, and the imaging surface of the second image collector 43 faces downward to face the inner ring shaft hole of the bearing 1 on the second light-transmitting plate 102. The second lifting drive can drive the second image collector 43 to approach the bearing to realize image acquisition of the inner wall of the bearing 1.

[0041] During detection, the surface light source 44 emits light upward, and the light passes through the second light-transmitting plate 102 and irradiates the bearing 1 thereon; the second lifting driver drives the second image collector 43 to move downward, so that the imaging surface of the second image collector 43 is close to the inner wall of the bearing 1, thereby collecting an image that meets the definition, so as to output it to the processing system for subsequent judgment. The mechanism has a simple structure, can achieve a high judgment accuracy, and the efficiency is also improved.

[0042] Furthermore, in this embodiment, the second lifting driver includes a slide 422 and a driving device 421. A vertical slide rail 411 is provided on the second support column 41. The slide 422 can be lifted and slidably matched on the slide rail 411. The driving device 421 drives and connects the slide 422 to control the lifting and lowering movement of the slide 422. The second image collector 43 is fixed on the slide 422. Guidance is achieved by the cooperation of the slide rail 411 and the slide 422, and the lifting and lowering movement of the second image collector 43 is more stable.

[0043] More specifically, the second support column 41 has a vertically extending inner cavity 401, the slide rail 411 is disposed in the inner cavity 401, the slide seat 422 includes a slider 4221 and a mounting frame 4222, the slider 4221 is disposed in the inner cavity 401 and cooperates with the slide rail 411; the mounting frame 4222 is disposed on the outer side of the second support column 41 and is fixedly connected to the slider 4221. The sliding matching structure is disposed in the inner cavity 401, and a hidden assembly is obtained, which plays a role of isolation and protection and will not be affected by other components.

[0044] More specifically, the driving device 421 includes a driving motor and a screw rod, wherein the driving motor is arranged at the top of the second supporting column 41, the screw rod is arranged in the inner cavity 401 and is threadedly matched with the slider 4221, and the upper end of the screw rod is connected to the rotating shaft of the driving motor. The driving device 421 and the slider 4221 are matched to each other. The matching structure is simple and the precision of controlling the lifting and moving is high.

[0045] Of course, in other embodiments, the structure of the second lifting actuator is not limited thereto. For example, the second lifting actuator may be directly implemented by using a cylinder, and the second image collector 43 may be directly connected to the piston rod of the cylinder.

[0046] Furthermore, in this embodiment, the second supporting column 41 is formed by splicing a plurality of connecting plates to achieve a detachable connection, thereby facilitating the loading and unloading operations of the internal components of the inner cavity 401 (such as the slider 4221, the screw rod, etc.).

[0047] Furthermore, in this embodiment, a plurality of position sensors 44 are provided on the second support column 41 from top to bottom, specifically three position sensors 44. More specifically, the position sensor 44 is a photoelectric sensor, and a trigger end for triggering the position sensor 44 is provided on the slide 422, and the trigger end is specifically a baffle 423 provided on the slide 422. When the slide 422 is lifted and slid to the point where the baffle 423 blocks the detection end of the photoelectric sensor, the photoelectric sensor is triggered, and the specific height of the slide 42 can be obtained, which is convenient for control. Of course, in other embodiments, the position detection structure is not limited to this, or, in the case where the control accuracy meets the standard, the position detection structure may not be required.

[0048] Furthermore, in this embodiment, the second light-transmitting plate 102 is a glass plate, which has good light transmittance and is cheap. Of course, in other embodiments, other light-transmitting resin plates may also be used.

[0049] Furthermore, in this embodiment, a conical surface 431 is formed on the periphery of the imaging surface of the lower end of the second image collector 43. With such a configuration, when the imaging surface of the second image collector 43 is close to the inner wall of the bearing 1 for imaging, the light irradiated to the periphery of the imaging surface will be reflected by the conical surface 431, and the light will not return again, thereby obtaining a clearer imaging surface.

[0050] Continue to refer to Figures 8 to 10 As shown, the lateral appearance / size imaging mechanism 50 includes a bearing support assembly, a peripheral illumination light source 53, a lateral parallel light source 54 and an image collector (defined as a third image collector 55). The bearing support assembly has a fixed station for fixing the bearing; specifically, the bearing support assembly includes a lower support assembly 51 located below and an upper clamping assembly 52 located above, and the lower support assembly 51 includes a lifting and rotating driving device 511 and a support seat 512 arranged on the lifting and rotating driving device 511. Specifically, the lifting and rotating driving device 511 is a device capable of lifting and rotating driving in the prior art. The support seat 512 is used to support the bearing 1. When the bearing 1 is transferred to the corresponding sixth station, the bearing 1 is supported by the support seat 512; then, the lifting and rotating driving device 511 drives the support seat 512 to move upward to realize the suspension of the bearing 1. The upper clamping assembly 52 includes a lifting drive device and a pressure rod 57 disposed on the lifting drive device. The pressure rod 57 is located above the support seat 512 and is driven by the lifting drive device to press down onto the bearing 1 of the support seat 512. Figure 8 In the state shown, the support seat 512 and the pressure rod 57 are pressed together to form a fixed position of the bearing support assembly.

[0051] The lateral parallel light source 54 is arranged at the front end of the fixed position of the bearing support assembly to emit parallel light backwards; the circumferential lighting light source 53 is arranged at the upper rear of the fixed position of the bearing support assembly to emit light downwards; the third image collector 55 is arranged at the rear end of the fixed position of the bearing support assembly.

[0052] When the peripheral appearance needs to be inspected, the peripheral illumination light source 53 is turned on, and the light emitted by the peripheral illumination light source 53 is irradiated to the peripheral side of the bearing 1 and reflected to the third image collector 55, thereby collecting the peripheral side image, which is convenient for output to the processing system for inspection. The lifting and rotating drive device 511 can also drive the bearing 1 to rotate circumferentially to realize the inspection of the entire periphery.

[0053] When it is necessary to detect the lateral dimension, the lateral parallel light source 54 emits parallel light from the front end to the rear end. The parallel light is reflected after passing through the bearing 1 on the fixed workstation, and the emitted light cannot be collected by the third image collector 55. In the image collected by the rear third image collector 55, the size of the shadow surface is the lateral dimension of the bearing 1. Of course, other components will also reflect light, such as the support seat and the pressure rod. In actual operation, they can be ignored and not used as a reference.

[0054] The mechanism can be used to detect the peripheral appearance and lateral dimensions of the bearing 1, achieving a two-in-one effect. The integration is good; the layout space of the machine is greatly reduced. The structure is simple and easy to implement.

[0055] For further information, please refer to Fig.10 As shown, the support seat 512 includes an insertion column 5121 for inserting into the inner ring of the bearing 1 and a contact step 5122 radially protruding from the insertion column 5121. The insertion column 5121 is inserted into the inner ring of the bearing 1, and then the lower surface of the bearing 1 abuts against the contact step 5122, thereby limiting the position of the bearing 1. At the same time, in order to ensure that the support seat 512 does not affect the subsequent lateral dimension detection, the diameter of the contact step 5122 is smaller than the diameter of the bearing 1, so as to ensure that the lower surface position of the bearing 1 can be confirmed.

[0056] Furthermore, it also includes a support frame 56, and the upper pressing assembly 52 and the peripheral illumination light source 53 are both arranged on the support frame 56 to obtain support and facilitate layout. Specifically, the support frame 56 is arranged between the fixed station and the third image collector 55. In order to avoid the support frame 56 from blocking the light, a clearance opening 561 is opened on the support frame 56.

[0057] More specifically, the rotation drive device of the upper clamping assembly 52 includes a driving cylinder 521, a connecting plate 522, a guide rod 523, an abutment block 525 and a spring 524. A guide sleeve 562 is provided on the support frame 56. The guide rod 523 is inserted into the guide sleeve 562 to play a guiding role. The driving cylinder 521 is fixed on the support frame 56. The piston rod of the driving cylinder 521 and the upper end of the guide rod 523 are connected through the connecting plate 522. The abutment block 525 is fixedly sleeved on the lower end of the guide rod 523. The spring 524 is arranged between the abutment block 525 and the guide sleeve 562. The pressing rod 57 is connected to the lower end of the guide rod 523. When pressing down, the driving cylinder 521 drives the pressing rod 57 to move down, and the elastic force applied by the spring 524 makes the pressing rod 57 move down more smoothly. When the pressure rod 57 moves downward for a certain distance, the spring 524 is stretched, exerting an upward elastic force on the pressure rod 57, so that the downward movement of the pressure rod 57 has a buffering effect, thereby preventing the bearing 1 from being damaged due to excessive force during downward pressure.

[0058] Of course, in other embodiments, the structure of the bearing support assembly is not limited thereto.

[0059] Furthermore, in this embodiment, the peripheral illumination light source 53 is a semi-annular light source, which has a large illumination area and a wide range, and better imaging. Of course, in other embodiments, the structure of the peripheral illumination light source 53 is not limited to this.

[0060] Furthermore, in this embodiment, the third image collector 55 is slidably disposed on a fixed seat 58 , and focusing is achieved by adjusting the front and rear positions of the third image collector 55 to obtain the best imaging pattern.

[0061] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
