[0002] Chinese utility model patent CN211606337U discloses a snap ring feeding mechanism for a rotor assembly station. This snap ring feeding mechanism includes a snap ring base plate, a snap ring feeding cylinder mounted on the base plate, a snap ring positioning plate at the front end of the cylinder, and a moving groove within the positioning plate. A snap ring placement frame is mounted on the positioning plate, and multiple snap rings are arranged sequentially vertically on the frame. The front end of the snap ring feeding cylinder drives a lower snap ring located in the moving groove to move forward via a snap ring pusher plate, thus feeding the snap ring.

[0032] Reference Figure 2 and Figure 3The stacking assembly 200 includes a stacking component 210, a pressing block 220, and a pressing plate 230. The stacking component 210 is vertically fixed on the feeding platform 140 and includes a stacking fixing plate 211a, a connecting rod 212, and a guide rod 213. The stacking fixing plate 211a is used to connect to the feeding platform 140; the connecting rod 212 is a slender rod with a rectangular cross-section, which is vertically arranged and connects the stacking fixing plate 211a and the guide rod 213; the guide rod 213 is a vertically arranged slender rod, with one side connected to the connecting rod 212 being a flat surface and the other side away from the connecting rod 212 being an arc surface, which can fit against the inner ring of the retaining spring 010. In this embodiment, the stacking fixing plate 211a and the connecting rod 212 are arranged perpendicular to each other. The retaining springs 010 are successively fitted onto the stacking component 210 from top to bottom to form a stack of retaining springs 010. The inner ring of the retaining ring 010 fits against the arc surface of the guide rod 213, and the connecting rod 212 passes through the retaining ring gap 001 of the retaining ring 010. The pressure block 220 is slidably sleeved on the guide rod 213 and contacts the upper surface of the uppermost retaining ring 010, so that the pressure block 220 presses the stacked retaining rings 010 tightly. The pressure block 220 can slide upward and disengage from the guide rod 213 to facilitate the replenishment of retaining rings 010. The pressure plate 230 is fixedly connected to the feeding table 140 and fits against the upper surface of the feeding table 140. The pressure plate 230 has a vertically formed guide groove that communicates with the sliding groove 141. The cross-section of the guide groove matches that of the retaining ring 010, and the guide groove provides guidance and positioning for the retaining rings 010 stacked at the bottom.

[0033] Reference Figure 4 and Figure 5 The feeding assembly 300 includes a feeding cylinder 310 and a feeding plate 320. The cylinder body of the feeding cylinder 310 is fixed to the vertical plate 120, and the piston rod of the feeding cylinder 310 is fixedly connected to the initial end of the feeding plate 320. The feeding plate 320 is a slender thin plate, and its length direction is consistent with the extension direction of the sliding groove 141, allowing the feeding plate 320 to slide within the sliding groove 141. The end of the feeding plate 320 faces the stacked snap rings. In this embodiment, the end of the feeding plate 320 is set as a pointed tip, which can pass through the snap ring gap 001, such as... Figure 5 As shown in (a).

[0034] Reference Figure 2 and Figure 6The detection component 400 includes a stacking detection component 410 and a feeding detection component 420. The stacking detection component 410 includes a detection fixing plate 411, a connecting plate 412, and a detection sensor 413. The detection fixing plate 411 is vertically fixed to the feeding table 140, and the stacking fixing plate 211a of the stacking component 210 is connected to the feeding table 140 through the detection fixing plate 411. The detection fixing plate 411 has multiple mounting holes on its side, arranged vertically at intervals. The connecting plate 412 is fixedly connected to the mounting holes of the detection fixing plate 411 by bolts. By connecting to different mounting holes, the height of the connecting plate 412 can be changed. The detection sensor 413 is fixed to the connecting plate 412, and its height is defined as a specific height. The detection sensor 413 is used to detect the presence of a retaining ring 010 at this specific height; it uses sensors that can achieve this function in the prior art, which are not listed here individually. The feeding detection component 420 is set at both ends of the detection groove 143 to detect whether the position of the detection groove 143 has a retaining ring 010. The sensor that can achieve this function in the prior art is selected, and will not be listed one by one here.

[0035] Reference Figure 4 The transfer assembly 500 includes a transfer cylinder 510 and a transfer member 520. The cylinder body of the transfer cylinder 510 is fixed on the worktable 130, and its piston rod is fixedly connected to the transfer member 520. A retaining ring 010 for picking up materials in the feed trough 142 by a suction device can be fixedly installed on the transfer member 520.

[0036] During the feeding of snap ring 010, the piston rod of the feeding cylinder 310 retracts, causing the feeding plate 320 to slide closer to the stacking member 210. The tip of the feeding plate 320 inserts into the snap ring gap 001 of the lowest snap ring 010, causing the lowest snap ring 010 to move in the sliding groove 141. When the outer ring of the snap ring 010 abuts against the feeding groove 142, the feeding of the snap ring 010 is completed. At this time, the feeding detection member 420 detects the snap ring in the detection groove 143 and drives the transfer cylinder 510 to move, causing the transfer member 520 to move closer to the feeding groove 142. The transfer member 520 can be equipped with a snap ring 010 pickup setting. After picking up the snap ring 010, the driving transfer cylinder 510 resets, and the snap ring 010 is transferred to other equipment for installation. Simultaneously, the piston rod of the feeding cylinder 310 extends and resets. Under the gravity of the pressing block 220 and the retaining spring 010, the stacked retaining springs 010 move downwards as a whole, completing the preparation for the next feeding of retaining springs 010. When the stacking detection component 410 cannot detect the retaining spring 010, the pressing block 220 is removed and a retaining spring 010 is added. Example

[0037] Reference Figure 7 A snap ring feeding mechanism includes a frame assembly 100, a stacking assembly 200, a feeding assembly 300, a detection assembly 400, and a transfer assembly 500.

[0038] Reference Figure 7 and Figure 9 The frame assembly 100 is fixedly mounted on the ground and includes a base plate 110 that is flush with the ground, a vertical plate 120 perpendicular to the ground, and a feeding platform 140 parallel to the ground. The vertical plate 120 is fixedly supported between the base plate 110 and the feeding platform 140, so that the feeding platform 140 is positioned at a suitable working height. The feeding platform 140 has a horizontally formed sliding groove 141, the starting end of which passes through the feeding platform 140 and communicates with the outside, while the ending end does not pass through the feeding platform 140.

[0039] Reference Figure 8 and Figure 10 The stacking assembly 200 includes a stacking component 210, a pressing block 220, and a pressing plate 230. The stacking component 210 is vertically fixed on the feeding platform 140 and includes a stacking fixing plate 211b, a connecting rod 212, and a guide rod 213. The stacking fixing plate 211b is fixedly connected to the feeding platform 140. The connecting rod 212 is a slender rod with a rectangular cross-section, which is vertically arranged and connects the stacking fixing plate 211b and the guide rod 213. The guide rod 213 is a vertically arranged slender rod, with one side connected to the connecting rod 212 being a flat surface and the other side away from the connecting rod 212 being an arc surface, which can fit against the inner ring of the retaining spring 010. In this embodiment, the stacking fixing plate 211b and the connecting rod 212 coincide in the vertical plane. The pressure plate 230 is fixedly connected to the feeding table 140, and the pressure plate 230 is attached to the upper surface of the feeding table 140. The pressure plate 230 has a vertically formed guide groove that communicates with the sliding groove 141. The cross-section of the guide groove matches the snap ring 010, and the guide groove provides guidance and positioning for the snap ring 010 stacked at the bottom.

[0040] Reference Figure 9 The feeding assembly 300 includes a feeding cylinder 310 and a feeding plate 320. The cylinder body of the feeding cylinder 310 is fixed to the vertical plate 120, and the piston rod of the feeding cylinder 310 is fixedly connected to the initial end of the feeding plate 320. The feeding plate 320 is a slender thin plate, and its length direction is consistent with the extension direction of the sliding groove 141. The feeding plate 320 can slide in the sliding groove 141. The end of the feeding plate 320 faces the stacked snap ring. In this embodiment, the end of the feeding plate 320 is set as a smooth end, which can abut against the outer ring of the snap ring 010 away from the snap ring gap 001. The smooth end can be set as follows: Figure 5 The plane shown in (b) can also be set as follows: Figure 5 (c) The concave arc surface matches the arc shape of the retaining ring 010.

[0041] The placement of the smooth end and the pointed end can be selected based on the position of the retaining spring 010 and the overall production line structure. When the retaining spring gap 001 of the retaining spring 010 needs to be positioned towards the feed plate 320, it is preferable to set the end of the feed plate 320 as a pointed end. The pointed end can pass through the retaining spring gap 001, which can more stably push the retaining spring 010 to move and reduce displacement of the retaining spring 010 during movement. When the retaining spring gap 001 of the retaining spring 010 needs to be positioned away from the feed plate 320, it is preferable to set the end of the feed plate 320 as a smooth end, so that the force exerted by the feed plate 320 on the retaining spring 010 is more uniform.

[0042] Reference Figure 9 and Figure 10 The detection component 400 includes a stacking detection element 410, which includes a connecting plate 412 and a detection sensor 413. A vertical plate 120 extends above the feeding platform 140 and has multiple mounting holes arranged vertically at intervals. The connecting plate 412 is fixedly connected to the mounting holes of the detection fixing plate 411 by bolts. The height of the connecting plate 412 can be changed by connecting to different mounting holes. The detection sensor 413 is fixed to the connecting plate 412 and is used to detect the presence of a retaining spring 010 at that position. Sensors that can perform this function in the prior art are selected, and are not listed here individually.

[0043] Reference Figure 10 The transfer assembly 500 includes a transfer cylinder 510, a transfer component 520, and a discharge sleeve 530. The cylinder body of the transfer cylinder 510 is vertically fixed on the worktable 130, and its piston rod is fixedly connected to the transfer component 520. The discharge sleeve 530 is fixedly connected to the feeding table 140, and it has a vertically penetrating discharge hole that communicates with the sliding groove 141.

[0044] During the feeding process of the retaining spring 010, the piston rod of the feeding cylinder 310 retracts, causing the feeding plate 320 to slide closer to the stacking member 210. After the smooth end of the feeding plate 320 abuts against the outer ring of the retaining spring 010, it moves the lowest retaining spring 010 to the end of the sliding groove 141, and then slides to the position corresponding to the discharge hole of the discharge sleeve 530, thus completing the feeding of the retaining spring 010. At this time, the driving transfer cylinder 510 moves, causing the transfer member 520 to move closer to the retaining spring 010 in the discharge sleeve 530. Under the action of the transfer member 520, the retaining spring 010 falls from the discharge hole to other mechanisms, completing the transfer of the retaining spring 010.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
