Description

Technical Field

[0001] This invention belongs to the technical field of oil seal testing equipment, specifically relating to an oil seal defect detection device. Background Technology

[0002] Oil seal is a common term for general sealing components; simply put, it's a seal for lubricating oil. It's a mechanical component used to seal grease (oil is the most common liquid substance in transmission systems, and also refers to any liquid substance in general). It isolates the lubricated parts from the output parts in the transmission system, preventing lubricating oil leakage. Both static and dynamic seals use the same type of sealing component called an oil seal.

[0003] Oil seals need to be inspected after production to reduce the rate of defective products shipped later. Therefore, an automatic inspection device is needed to automatically inspect and return materials to achieve automated inspection of oil seals. Summary of the Invention

[0017] The beneficial effects of this invention are as follows:

[0018] 1. By setting up a feeding turntable and a discharging turntable, the two work together, and multiple first material trays are set on the surface, which can be used to store the test objects. With the help of the first reduction motor at the bottom, the mounting plate can be driven to rotate. At the same time, a first turntable and a first rotating groove are set below the first material tray. The first limiting rod inserted on the first material tray can slide and insert in the first rotating groove of the first turntable. By rotating the first turntable, the material is clamped. With the help of the first limiting sleeve, the friction of the first limiting rod in the first material tray is increased. At the same time, the size between different first limiting rods can be easily adjusted for materials of different sizes, thereby increasing the clamping effect.

[0019] 2. By setting a lifting mechanism at the bottom of the feeding turntable and the unloading turntable, the output screw is rotated by the second reduction motor. The rotation of the screw drives the slide and the lifting rod to move upward. The lifting rod positions the first material tray above through the positioning hole on the mounting plate. After clamping the material of a single first material tray, it rotates again to cooperate with the lifting rod to position the next one, and then takes the shaft seal from the next first material tray.

[0020] 3. By setting a stripping structure on the side of the feeding turntable device, the stripping structure can be adjusted up and down by the first cylinder, and a first gripper cylinder is set on the bottom plate at the top. By setting a first mounting tube and gripper on the two output ends, it can clamp the shaft seal below when the Scara robot picks up the shaft seal, preventing the second shaft seal from sticking to the bottom and being picked up at the same time when the Scara robot picks up the shaft seal.

[0021] 4. By setting an imaging module on the second partition at the rear, which adopts existing equipment with high integration, it can take pictures of the object to be detected placed under the supplementary light cover and transmit the data to the processing equipment. At the same time, the negative pressure stage below can adsorb the workpiece, and together with the third reduction motor and the second belt drive structure below, it can realize the rotation during detection, thereby increasing the shooting effect of the imaging module.

[0022] 5. By setting a cleaning mechanism on the second partition, it is inevitable that particulate matter will adhere to the surface of the shaft seal after production and transportation, which will affect the processor's judgment during imaging module shooting. Therefore, it is necessary to clean the surface before shooting. By setting a second material tray with multiple holes, together with the bottom sealing cover and the micro plasma fan set inside, the shaft seal can be blown inside the sealing cover, so that the residual particles on the surface can be discharged through the waste discharge hole in the second material tray.

[0045] The principle of this invention: The shaft seals to be tested are placed on the first material tray 23 of the feeding turntable device 2. By rotating the first turntable 24 at the bottom, multiple first limiting rods 27 on its surface move through the first rotating groove 25. Under the limitation of the first sliding groove 231, the first limiting rods 27 clamp the shaft seals. The main mechanism is that the movement of the Scara robot 7 drives the first two-finger flat gripper structure 71 at the output end to clamp the shaft seals on the first turntable 24. At the same time, during the clamping process, the first cylinder 52 of the unloading structure 5 is opened, which drives the bottom plate 53 at the output end and the first gripper cylinder 54 to rise. The gripper 56 at the output end of the first gripper cylinder 54 clamps the next bearing of the shaft seal clamped by the Scara robot 7, preventing the Scara robot 7 from clamping two shaft seals at the same time. According to the reduction of the number of bearings in a single first turntable 24, the first cylinder 52 can be adjusted up and down, so that the first gripper cylinder 54 can clamp at the corresponding height synchronously.

[0046] After the shaft seal in one of the first turntables 24 is clamped, the bottom lifting rod 46 descends, causing the mounting plate 21 to be limited by the lifting rod 46. At this time, the first reduction motor 210 at the bottom is turned on to rotate the mounting plate 21. After the mounting plate 21 moves to one station, the bottom lifting rod 46 drives the lead screw 43 to rotate through the second reduction motor 47, causing the first slide 45 on the surface of the second lead screw 43 to move upward, thereby pushing the lifting rod 46 installed on one side to move upward, so that the lifting rod 46 is inserted into the positioning hole 22 in the mounting plate 21. After the movement of the mounting plate 21 is limited, the Scara robot 7 can clamp the shaft seal in the first material tray 23 in the next station.

[0047] The SCARA robot 7 clamps the shaft seal onto the second feeding tray 106. Two second clamping blocks 108 on the second feeding tray 106 limit and clamp the inner ring of the shaft seal. Then, the top third cylinder 102 moves the sealing cover 104 downwards to cover the bottom second feeding tray 106. Next, the fourth reduction motor 1010 on one side is activated, causing it to rotate the top-connected second turntable 1013. The rotation of the second turntable 1013 causes the connectors inserted into the second rotating groove 1014 along the second rotating groove 1014. 014 begins to rotate, causing the second clamping block 108 at the top to expand or clamp outward or inward. Depending on the size requirements of different shaft seals, smaller bearings are clamped, while larger bearing shaft pairs are held in place by the second clamping block 108. Clamping is achieved by expanding. Then, the miniature plasma fan inside the sealing cover 104 turns on and blows downward to the shaft seal. At the same time, the vacuum cleaner connected to the leak-proof cover 1012 turns on in sync with the miniature plasma fan to collect the blown particles outward, while also preventing internal particles from flying away.

[0048] After cleaning, the sealing cover 104 and the fourth reduction motor 1010 are closed. The electric slide 91 is opened, which moves the sixth mounting bracket 92 at the output end to the rear of the second material tray 106. The second two-finger flat gripper structure 95 at the front end of the sixth mounting bracket 92 is moved above the cleaned bearing. At this time, the second cylinder 93 is opened and lowered. The first clamping block 953 at the output end of the second two-finger flat gripper structure 95 clamps the bearing below. Then the second cylinder 93 rises and, together with the electric slide 91, moves the shaft seal to the top of the negative pressure platform 82. The shaft seal is placed on the surface of the negative pressure platform 82. Then the negative pressure device at the bottom of the negative pressure platform 82 is turned on to adsorb the shaft seal, so as to prevent the shaft seal from shifting when the third reduction motor 822 and the second belt drive structure 823 are rotating. At this time, the negative pressure platform 82 rotates and, together with the top supplementary light cover 81, turns on the illumination. Together with the imaging module 8 on one side, it takes a picture and records it into the processor. The processor judges it.

[0049] Once a defective product is detected, the Scara robot 7 clamps the shaft seal onto a conveyor belt 61 in the waste recycling device 6. The waste shaft seals are stacked vertically by the side fence frame 62. At the same time, the conveyor belt 61 can be moved by the first stepper motor 65 in conjunction with the first belt drive structure 63, moving the stacked shaft seals backward. This allows multiple waste shaft seals to be placed on the conveyor belt 61. The use of multiple conveyor belts 61 increases the collection time of internal waste.

[0050] Once the inspection is passed, the scara robot 7 moves the shaft seal to the side unloading turntable 3, which moves in the same way as the loading turntable 2. When one of the first material trays 23 is full of shaft seals, it rotates one station to collect them in the next first material tray 23.

[0051] The device uses different sensors to detect parts and stop the machine. The use of these sensors is based on existing technology and will not be described in detail in this article.

[0052] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
