Abstract
Description

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
[0003] After the bearing is processed and put into use, it needs to be inspected. For the appearance inspection of the bearing, it is mainly to check whether there are scratches and rust on the outer surface of the bearing, whether the rivets on the upper and lower end faces are riveted well and whether there are missing steel balls. For the size inspection of the bearing, it is mainly to check whether the inner hole diameter of the bearing is qualified.
[0004] At present, there are production lines on the market that automatically inspect bearings. During the inspection process, the bearings need to be transported to various workstations, and the bearings that fail the inspection need to be kicked out of the production line. At present, when kicking out defective bearings, the defective bearings fall to the defective product collection area by falling, and the bearings will have a high height difference. Since some of the defective bearings kicked out can be reprocessed to become good products, but during the falling process, the appearance of the bearings will be damaged and scrapped, and rework is impossible, which increases the scrap rate of the bearings.
[0005] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a ring-type parts discharging mechanism to make it more valuable for industrial use. Summary of the invention

DETAILED DESCRIPTION
[0031] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 those skilled in the art without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0034] like Figure 1 As shown, the ring parts discharging mechanism of the present invention includes a pick-up device 10, an aligning device 20 and a discharging device 30. Among them, the pick-up device 10 can pick up the ring parts 40 from the conveying line 50 conveying the ring parts 40 and send them to the aligning device 20; the discharging device 30 is located below the conveying line 50; the aligning device 20 can push the ring parts 40 obtained by the pick-up device 10 to the discharging device 30. The pick-up device 10 is used to pick up the defective ring parts 40 (such as bearings) from the conveying line 50 after inspection and send them to the aligning device 20, and the aligning device 20 is used to push the ring parts 40 obtained by the pick-up device 10 to the discharging device 30 located below the conveying line 50. During the whole process, the free falling height of the ring parts 40 is relatively low, achieving a low drop height, ensuring that the appearance of the ring parts 40 is not damaged, ensuring the rework rate, and reducing the scrap rate caused by bumps.
[0035] Specifically, Figure 2 and Figure 3As shown, the material taking device 10 is located at the side of the conveyor line 50 and the discharging device 30 on the same side, and the material taking device 10 includes a support 15 and a hooking assembly 11, a material guide 12, a feeding assembly 13, and a pushing assembly 14 arranged on the support 15. Among them, the hooking assembly 11 can hook the ring-like parts 40 from the conveyor line 50 to the material guide 12; the material guide 12 is located below the hooking assembly 11 and adjacent to the conveyor line 50, and the material guide 12 can guide the ring-like parts 40 to fall and turn 90 degrees; the feeding assembly 13 can receive the ring-like parts 40 transmitted by the material guide 12 and send them to the pushing assembly 14; the pushing assembly 14 is located below the feeding assembly 13, and the pushing assembly 14 is configured to push the ring-like parts 40 to fall onto the arranging device 20. It can be seen that the ring-like parts 40 will only flip over and freely fall a certain distance under the guidance of the material guide 12 during the process of reaching the arranging device 20 below from the conveyor line 50 above. Compared with directly falling freely from the conveyor line 50 to the discharging device 30, the height difference of the ring-like parts 40 is greatly reduced, and a low-drop descent is achieved, thereby avoiding collisions of the ring-like parts 40.
[0036] In order to enable the hooking assembly 11 to hook the ring-like part 40 from the conveyor line 50 to the material guide 12, the hooking assembly 11 of the present invention includes a hook head 111 and a first cylinder 112 for driving the hook head 111 to reciprocate in the horizontal direction relative to the conveyor line 50. When the hook head 111 extends to the conveyor line 50 and contacts the ring-like part 40, the hook head 111 can rotate, and the first cylinder 112 continues to drive the hook head 111 to extend. When the hook head 111 extends to the center hole of the ring-like part 40, the hook head 111 rotates and extends into the center hole, the first cylinder 112 retreats, and the hook head 111 pulls the ring-like part 40 to move. When the ring-like part 40 moves out of the conveyor line 50, it falls onto the material guide 12 under the action of its own gravity. The material guide 12 guides the ring-like part 40 to fall and flip 90°, so that the flat-lying ring-like part 40 becomes a vertical state.
[0037] In order to enable the feeding assembly 13 to receive the ring-like parts 40 conveyed by the material guide 12 and to deliver them to the pushing assembly 14, the feeding assembly 13 in the present invention includes a receiving member and a second cylinder 133 that drives the receiving member to reciprocate in the vertical direction relative to the pushing assembly 14. The receiving member is configured to receive the ring-like parts 40 after being turned over 90°. In order to enable the receiving member to receive the ring-like parts 40 in a vertical state, the receiving member includes a receiving plate 131 and a baffle 132 connected to the receiving plate 131. The receiving plate 131 has a groove for supporting the ring-like parts 40. In addition, as Figure 4 As shown, the guide member 12 is a bent arc structure (bending angle is 90°), and a channel for clamping the ring-like parts 40 is formed between the guide member 12 and the receiving member. The channel can only clamp the ring-like parts 40 in the vertical state, so as to prevent the ring-like parts 40 from turning over again and affecting the subsequent pushing and arranging operations.
[0038] As a preferred embodiment of the present invention, the width of the channel between the guide member 12 and the receiving member of the present invention can be adjusted. Specifically, a waist-shaped hole 121 can be set on the guide member 12 to be installed with the support 15, and the length of the waist-shaped hole 121 can be set according to demand so as to guide the ring parts 40 of different thicknesses.
[0039] The function of the pusher assembly 14 is to push the ring-like parts 40 away from the receiving plate 131 so that the ring-like parts 40 fall onto the arranging device 20 in a low-drop manner. Specifically, the pusher assembly 14 includes a pusher head 141 that can pass through both sides of the receiving member and a third cylinder 142 that drives the pusher head 141 to reciprocate in the horizontal direction. The pusher head 141 can be two pusher plates arranged in parallel, and the distance between the two pusher plates is greater than the width of the baffle 132 and less than the outer diameter of the ring-like parts 40.
[0040] When the ring-like parts 40 fall off the receiving plate 131, the aligning device 20 starts to work. The aligning device 20 in the present invention includes an aligning pusher 21 and a fourth cylinder 22 that drives the aligning pusher 21 to reciprocate relative to the discharging device 30; the discharging device 30 includes at least one aligning groove and a string rod 31 that can string together a plurality of ring-like parts 40, and the string rod 31 is arranged on the aligning groove. In the present invention, the aligning pusher 21 can be placed on the aligning groove, and the fourth cylinder 22 drives the aligning pusher 21 to move along the aligning groove. In this way, when the ring-like parts 40 fall from the receiving plate 131 to the entire row pusher 21, the fourth cylinder 22 drives the entire row pusher 21 to move away from the discharge device 30. At this time, the ring-like parts 40 fall from the entire row pusher 21 to the end of the entire row slot, and then the fourth cylinder 22 extends to push the ring-like parts 40 away from the end of the entire row slot to enter the discharge device 30, and also reserves space for the ring-like parts 40 to fall later.
[0041] The working principle of the ring parts discharging mechanism of the present invention is:
[0042] When the ring-like parts 40 are detected and judged to be defective, they are transported by the conveyor line 50, the hooking assembly 11 hooks the ring-like parts 40, and then passes through the material guide 12 and vertically falls onto the receiving plate 131, and then the receiving plate 131 descends, and the third cylinder 142 pushes the ring-like parts 40 above the alignment pusher 21, and the fourth cylinder 22 drives the alignment pusher 21 to retreat, and the ring-like parts 40 fall into the alignment groove, and the fourth cylinder 22 moves forward to push the ring-like parts 40 forward, so that the low-drop alignment of the defective ring-like parts 40 is achieved reciprocatingly.
[0043] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
