Description

Technical Field

[0001] The present invention belongs to the field of conveying technology, and specifically relates to arranging objects by means of machinery during a feeding process, and more particularly to a roller conveying production equipment and a production process thereof. Background Art

[0002] When assembling large bearings, the curvature of the rollers needs to be tested, mainly to ensure the normal operation of the bearings and extend their service life. The rollers are important components in the bearings, and their curvature directly affects the rotation accuracy and load-bearing capacity of the bearings. By testing the curvature of the rollers, defects in the manufacturing process can be discovered and resolved in a timely manner, thereby improving the quality and reliability of the bearings.

[0003] In the related art, the curvature of the roller is detected in the following ways: The first type is traditional manual inspection, which is carried out by combining auxiliary tooling and manual visual inspection. It has problems of low efficiency and low reliability and cannot meet large-scale production needs.

[0004] The second type is machine vision inspection, which uses machine vision technology to perform online inspection of chamfered surfaces and surface defects of bearing rollers. However, the cost of machine vision inspection equipment and its related software and hardware systems is relatively high. At the same time, machine vision inspection is sensitive to light, temperature, and humidity. When the light, temperature, and humidity change greatly, it will affect the brightness, color tone, and atmosphere of the photo, thereby affecting the shooting accuracy, resulting in image recognition errors, and prone to false alarms and missed alarms.

[0005] Therefore, how to avoid the influence of changes in environmental factors on detection accuracy during roller conveying is an urgent problem to be solved.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0026] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] See also Figure 1 , Figure 1The schematic diagram of the structure of the roller conveying production equipment is shown, including: a control module, a feeding mechanism 100, a conveying mechanism 200, a vibrating unloading mechanism 300 and a discharging detection mechanism 400; the feeding mechanism 100 is arranged on the feeding side of the conveying mechanism 200; the discharging end of the conveying mechanism 200 is connected with the feeding end of the vibrating unloading mechanism 300; the discharging end of the vibrating unloading mechanism 300 is connected with the feeding end of the discharging detection mechanism 400; the discharging detection mechanism 400 is suitable for detecting the curvature of the roller 500 and sending the detection result to the control module; the control module is suitable for screening and conveying the roller 500 according to the detection result. By designing a discharging detection mechanism 400 that is not affected by environmental changes to detect the curvature of the roller 500, and adding it to the existing roller 500 conveying equipment, automatic detection is completed during the conveying process, thereby improving the detection efficiency.

[0029] See also Figure 2 In some embodiments, the discharge detection mechanism 400 includes: a conveying trough 410; a push cylinder 420, which is arranged in the conveying trough 410 and is suitable for pushing the roller 500 from the feeding end of the conveying trough 410 to the discharging end of the conveying trough 410; and a detection head 430, which is arranged on the piston rod of the push cylinder 420 and is suitable for detecting the curvature of the side wall of the roller 500. By arranging the push cylinder 420 and the detection head 430 in the conveying trough 410, the push cylinder 420 drives the detection head 430 to extend and retract, thereby completing the conveying and detection of the roller 500.

[0030] Since the side surface of the roller 500 is an arc surface, and the diameter of the middle part of the roller 500 is larger than the diameter of the two end parts, in order to prevent the roller 500 from getting stuck in the conveying trough 410 when it deviates, in a preferred embodiment, the detection head 430 includes a detection block 431; the shape of the side wall of the detection block 431 is adapted to the side wall of the roller 500; the side wall of the detection block 431 is provided with a suction port 4311, and the suction port 4311 is suitable for sucking the roller 500; the suction port 4311 is connected to the vacuum tube of an external vacuum pump; the detection head 430 is also provided with a sound collection sensor 4312; the sound collection sensor 4312 is configured to detect the leakage sound information when the suction port 4311 is in contact with the side wall of the roller 500, and send it to the control module. By opening an adsorption port 4311 on the side wall of the detection block 431, the roller 500 is adsorbed to prevent the roller 500 from deviating during transportation. At the same time, since the shape of the side wall of the detection block 431 is adapted to the side wall of the roller 500, when the curvature of the side wall of the roller 500 does not match the preset curvature, there will be a gap between the side wall of the detection block 431 and the side wall of the roller 500. At this time, external gas will be sucked into the detection block 431 through the gap, thereby making a sound. The sound is collected by the sound collection sensor 4312 to obtain the leakage sound information and send it to the control module to complete the detection of the curvature of the side wall of the roller 500. The acoustic detection method is used to avoid noise interference, thereby solving the problem of visual detection relying on the environment. Please continue reading Figure 2-Figure 3 In some embodiments, the discharge detection mechanism 400 further includes a screening cylinder 440; the conveying trough 410 includes a first discharge port 411 and a second discharge port 412; the control module is configured to control the screening cylinder 440 to push the roller 500 out of the second discharge port 412 when receiving the air leakage sound information and the pushing cylinder 420 conveys the roller 500 to the piston rod of the screening cylinder 440; the control module is also configured to control the pushing cylinder 420 to push the roller 500 out of the first discharge port 411 when the air leakage sound information is not received and the pushing cylinder 420 conveys the roller 500 to the piston rod of the screening cylinder 440. By setting the screening cylinder 440, the roller 500 with unqualified curvature is pushed out of the second discharge port 412, and the roller 500 with qualified curvature is pushed out of the first discharge port 411, thereby completing the screening.

[0031] Specifically, the sieving cylinder 440 is arranged outside the conveying trough 410; the piston rod of the sieving cylinder 440 is embedded in the side wall of the conveying trough 410, and the end surface of the piston rod of the sieving cylinder 440 is in contact with the inner side wall of the conveying trough 410. The piston rod of the sieving cylinder 440 is embedded in the side wall of the conveying trough 410 to avoid interference with the conveying of the roller 500.

[0032] Please continue reading Figure 2 In order to detect the curvature of all side walls of the roller 500, in at least one embodiment, the discharge detection mechanism 400 further includes a friction block 450; the friction block 450 is disposed above the conveying trough body 410, and the distance between the bottom surface of the friction block 450 and the bottom wall of the conveying trough body 410 is smaller than the maximum diameter of the roller 500. The push cylinder 420 pushes the detection head 430 under the friction block 450, thereby driving the roller 500 to rotate through the friction block 450, so that all sides of the roller 500 pass through the suction port 4311 of the detection block 431, thereby completing the curvature detection of all side walls of the roller 500.

[0033] It should be noted that the friction block 450 is made of rubber. The friction force between the friction block 450 and the roller 500 is sufficient to overcome the adsorption force of the adsorption port 4311 on the roller 500, so that the roller 500 rotates when passing through the friction block 450.

[0034] See also Figure 4 In at least one embodiment, the feeding mechanism 100 includes: a feeding box 110, a pushing block 120 and a driving assembly 130; the pushing block 120 is slidably arranged on the side wall of the feeding box 110 and is located below the feeding port 111 of the feeding box 110; the driving assembly 130 is configured to drive the pushing block 120 to be pushed from the bottom surface of the hopper of the feeding box 110 to the feeding port 111 of the feeding box 110, thereby pushing the roller 500 in the hopper of the feeding box 110 out of the feeding port 111 of the feeding box 110.

[0035] Specifically, the pushing block 120 includes: a connecting block 121, a first push plate 122, a second push plate 123 and a third push plate 124; the first push plate 122 and the third push plate 124 are arranged at intervals and are both arranged on the top surface of the connecting block 121; the second push plate 123 is arranged on both sides of the loading box 110; the height of the first push plate 122 is greater than the height of the third push plate 124; the top surfaces of the first push plate 122, the second push plate 123 and the third push plate 124 are all inclined surfaces and are arranged toward the loading port 111 of the loading box 110; the driving assembly 130 is configured to drive the connecting block 121 to slide along the side wall of the loading box 110, thereby driving the first push plate 122 and the third push plate 124 to rise and fall synchronously.

[0036] The bottom surface of the hopper of the upper material box 110 is inclined. When the roller 500 is placed in the upper material box 110, the roller 500 directly falls along the inclined bottom surface onto the pusher block 120. When the pusher block 120 pushes the material, the drive assembly 130 first drives the connecting block 121 to descend, so that the top surface of the third push plate 124 and the bottom surface of the hopper are in the same plane. At this time, the roller 500 falls to the top surface of the third push plate 124, and then the drive assembly 130 drives the connecting block 121 to rise, so that the top surface of the third push plate 124 is aligned with the second push plate 123. The top surfaces of the first push plate 122 and the second push plate 123 are in the same plane. At this time, the roller 500 falls to the top surface of the second push plate 123, and the driving assembly 130 drives the connecting block 121 to descend, so that the top surface of the first push plate 122 and the top surface of the second push plate 123 are in the same plane. At this time, the roller 500 falls to the top surface of the first push plate 122. Finally, the driving assembly 130 drives the connecting block 121 to rise, so that the top surface of the first push plate 122 is flush with the loading port 111 of the loading box 110, thereby pushing the roller 500 out from the loading port 111 of the loading box 110.

[0037] Please continue reading Figure 4 In at least one embodiment, the driving assembly 130 includes: a driving cylinder 131, a rotating arm 132, a rotating support 133 and a connecting rod 134; the driving cylinder 131 is arranged below the hopper of the loading box 110; the rotating support 133 is arranged on the bottom frame of the loading box 110; the middle part of the rotating arm 132 is rotatably connected to the rotating support 133; the end of the piston rod of the driving cylinder 131 is slidably connected to one end of the rotating arm 132; one end of the connecting rod 134 is rotatably connected to the other end of the rotating arm 132, and the other end of the connecting rod 134 is rotatably connected to the connecting block 121.

[0038] When the driving cylinder 131 rises along F1, the connecting block 121 is driven to descend along F2 through the rotating arm 132 and the connecting rod 134, thereby driving the first push plate 122 and the third push plate 124 to descend; conversely, when the driving cylinder 131 descends along F1, the connecting block 121F2 is driven to rise through the rotating arm 132 and the connecting rod 134, thereby driving the first push plate 122 and the third push plate 124 to rise.
