Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figures 1 to 6 , an embodiment provided by the present invention:

[0027] A double-station feeding device for magnetic rings, including a storage component for storing multiple groups of magnetic rings 1, a pusher component for pushing the magnetic rings 1 upward, a clamping component for clamping the magnetic rings 1, and a transportation component 2 for driving the clamping component to move. The pusher component is located on one side of the storage component and corresponds to the position of the magnetic rings 1. The clamping component is arranged above the storage component and is vertically aligned with the pusher component. It is characterized in that: it further includes a pick-up station, a transfer station, and a feeding station arranged at equal intervals and horizontally aligned, and located below the clamping component. Taking one group of magnetic rings 1 as the initial group, the pick-up station corresponds to the position of the uppermost magnetic ring 1 of the initial group. The transfer station is provided with a transfer base 3 for placing the magnetic rings 1, and the feeding station is provided with a magnetron base 4 that cooperates with the magnetic rings 1 for installation; the clamping component includes two sets of grippers arranged at a horizontal interval and a linkage plate 6 connecting the two sets of grippers. The grippers are arranged to be openable and closable and extend downward. The distance between the two sets of grippers is A, the distance from the pick-up station to the transfer station is B, and the distance from the transfer station to the feeding station is C. The distance A = the distance B = the distance C.

[0028] The material storage component is horizontally rotatable. A number of magnetic rings 1 are stacked and divided into multiple groups stored in the material storage component. By rotating the material storage component, the positions of multiple groups of magnetic rings 1 can be switched to achieve the effect of material change. The material lifting component is vertically liftable and can push the magnetic ring 1 upward. The material lifting component is located on one side of the material storage component and corresponds to one group of magnetic rings 1 of the material lifting component. It can be located below the lowermost magnetic ring 1. When the material lifting component rises, it can lift the whole group of magnetic rings 1, thereby adjusting the height position of the uppermost magnetic ring 1 to make it reach the material taking station. The material clamping component is movably openable and can grab the magnetic ring 1 by clamping. The material clamping component is arranged above the material storage component. It can be located above one group of magnetic rings 1 of the material lifting component and is vertically aligned with the material lifting component. After the material lifting component lifts the whole group of magnetic rings 1, the material clamping component grabs the uppermost magnetic ring 1 located at the material taking station. The transportation component 2 adopts a cylinder drive mode to drive the material clamping component to move vertically and horizontally, thereby transporting the magnetic ring 1 and playing the role of replacing manual operation.

[0029] The material taking station, the transfer station, and the feeding station are arranged at intervals. The three are equally spaced, horizontally aligned, and located below the material clamping component. Among the multiple groups of magnetic rings 1 stored in the material storage component, one group of magnetic rings 1 is used as the initial group. The material clamping component and the material lifting component are respectively arranged according to the positions of the magnetic rings 1 in the initial group and are distributed on the upper and lower sides. The transfer base 3 is a circular table structure protruding upward and can place the magnetic ring 1 to play the role of transportation and transfer. The magnetron base 4 is cooperatively installed with the magnetic ring 1 to achieve the assembly purpose. It can be understood that the uppermost magnetic ring 1 of the initial group corresponds to the material taking station, the transfer base 3 corresponds to the transfer station, and the magnetron base 4 corresponds to the feeding station. Two sets of grippers are horizontally spaced, openable, and extend downward. The vertical distances from the grippers to the material taking station, the transfer station, and the feeding station are all equal. The linkage plate 6 is connected to the two sets of grippers to make the two sets of grippers move synchronously. The distance between the two sets of grippers is A, the distance from the material taking station to the transfer station is B, and the distance from the transfer station to the feeding station is C. The distance A = the distance B = the distance C, so that the two sets of grippers can be synchronously aligned with the material taking station and the transfer station, and synchronously aligned with the transfer station and the feeding station, playing a dual connection role.

[0030] In the present invention, by setting two sets of grippers that move synchronously. In the initial state, multiple groups of magnetic rings 1 are placed in the material storage component, and one group of magnetic rings 1 is used as the initial group. The material lifting component is aligned with the lowermost magnetic ring 1 of the initial group, the material clamping component is aligned with the uppermost magnetic ring 1 of the initial group, and a pre-installed magnetic ring 5 is placed on the transfer base 3.

[0031] When the magnetic ring 1 needs to be installed, the ejector assembly pushes the magnetic ring 1 upward until the uppermost magnetic ring 1 is at the picking station. The transportation assembly 2 drives the two sets of grippers to move downward synchronously. One set of grippers moves to the picking station and grips the uppermost magnetic ring 1, and the other set of grippers moves to the transfer station and grips the pre-installed magnetic ring 5.

[0032] Then, the transportation assembly 2 drives the two sets of grippers to move synchronously upward, horizontally, and downward in sequence until one set of grippers moves to the transfer station and places the uppermost magnetic ring 1 on the transfer base 3, and the other set of grippers moves to the feeding station and installs the pre-installed magnetic ring 5 on the magnetron base 4, completing the installation of the magnetic ring 1. By repeating the above process, it plays an automatic feeding role, and the clamping assembly uses double clamping. By adding a transfer station, the distance and time of a single transportation are shortened, effectively improving the assembly efficiency.

[0033] In this embodiment, preferably, the storage assembly includes a horizontally arranged tray 7, an indexer 8 for driving the tray 7 to rotate intermittently, and a number of material rods 9 vertically arranged outside the tray 7. Multiple sets of magnetic rings 1 are stacked and sleeved on the material rods 9 and are vertically aligned with the ejector assembly and the clamping assembly.

[0034] The tray 7 is horizontally arranged and has a disc-shaped structure. The indexer 8 is located below the tray 7 and can be a cam type indexer 8. When the input shaft of the indexer 8 rotates one week, the output shaft of the indexer 8 rotates one station and pauses, thereby realizing an intermittent rotary motion. The output shaft of the indexer 8 is coaxially connected to the tray 7. Under the action of the indexer 8, the tray 7 rotates intermittently to switch the relative positions of the material rods 9. The material rods 9 are located above the tray 7 and have a cylindrical structure, extending upward from the surface of the tray 7. A number of material rods 9 are evenly arranged along the outside of the tray 7. The outer diameter of the material rods 9 is equal to the inner diameter of the magnetic ring 1. A number of magnetic rings 1 are stacked and sleeved outside the material rods 9, and each material rod 9 corresponds to a set of magnetic rings 1. The ejector assembly is arranged below the material rods 9, and the clamping assembly is arranged above the material rods 9, and can be adjusted specifically according to the position of the initial set of magnetic rings.

[0035] In this embodiment, preferably, the outer edge of the tray 7 is provided with an outwardly extending fixing portion 10. The fixing portions 10 are evenly arranged around the outside of the tray 7. The material rods 9 are inserted above the fixing portions 10 and correspond to the fixing portions 10 one by one. The ejector assembly moves upward over the fixing portion 10 and abuts against the bottom of the magnetic ring 1.

[0036] The fixing part 10 is located at the outer edge of the material tray 7, extending outward, presenting a block structure, and evenly arranged around the outer side of the material tray 7. The material rod 9 is vertically connected to the top of the fixing part 10, corresponding to the fixing part 10 one by one. The lifting assembly is located below the fixing part 10, vertically aligned with both sides of the fixing part 10, and the width of the fixing part 10 is smaller than the outer diameter of the magnetic ring 1, leaving enough avoidance space for the lifting assembly. When the lifting assembly moves upward, it first passes over the fixing part 10, and then abuts against the bottom of the magnetic ring 1, thereby lifting the entire set of magnetic rings 1.

[0037] In this embodiment, as a preference, the lifting assembly includes a U-shaped plate 11 symmetrically arranged on both sides of the fixed part 10, and a lifting mechanism 12 for driving the U-shaped plate 11 to vertically lift and lower. The inner side of the U-shaped plate 11 is spaced apart from the outer side of the fixed part 10, and the top of the U-shaped plate 11 is horizontally abutted against the bottom of the magnetic ring 1.

[0038] The U-shaped plate 11 is horizontally arranged and extends toward the fixed part 10. The U-shaped plate 11 includes two legs, which are symmetrically arranged on both sides of the fixed part 10 to improve the balance of contact with the magnetic ring 1. The inner side of the U-shaped plate 11 and the outer side of the fixed part 10 are spaced apart to leave enough space for the top material assembly. The width dimension between the two legs is larger than the width dimension of the fixed part 10 and smaller than the outer diameter dimension of the magnetic ring 1. The lifting mechanism 12 includes a lifting plate connected to the U-shaped plate 11, a screw rod vertically inserted in the center of the lifting plate, and sliding rods symmetrically inserted on both sides of the lifting plate. The screw rod is transmission-connected to the lifting plate and is connected to a lifting motor. The sliding rod is slidingly connected to the lifting plate. Driven by the lifting motor, the screw rod rotates and drives the lifting plate to move upward, thereby controlling the vertical rise of the U-shaped plate 11, and the top of the U-shaped plate 11 is horizontally abutted against the bottom of the magnetic ring 1.

[0039] In this embodiment, as a preference, the transfer platform 3 is an upwardly protruding truncated cone-shaped structure, including a horizontally arranged support seat 13, and a positioning rod 14 inserted in the center of the support seat 13, and the magnetic ring 1 is mounted on the outside of the positioning rod 14 and abuts against the top of the support seat 13.

[0040] The transfer platform 3 is an upwardly protruding truncated cone-shaped structure, the positioning rod 14 and the support seat 13 are arranged up and down, the support seat 13 is arranged horizontally and is truncated cone-shaped, and the outer diameter of the support seat 13 is smaller than the outer diameter of the magnetic ring 1, which is convenient for the gripper to grab the magnetic ring 1 located on the transfer platform 3. The positioning rod 14 is inserted in the center of the support seat 13 and extends upward from the surface of the support seat 13. The outer diameter of the positioning rod 14 is equal to the inner diameter of the magnetic ring 1. When the gripper places the magnetic ring 1 on the transfer platform 3, the magnetic ring 1 is sleeved with the positioning rod 14 and abuts against the support seat 13.

[0041] In this embodiment, preferably, the magnetron base 4 includes an annular flange 15 provided at the center. The annular flange 15 extends upward and is arranged to match the magnetic ring 1. The magnetic ring 1 is sleeved outside the annular flange 15 and is horizontally aligned with the support base 13.

[0042] The annular flange 15 is located at the center of the magnetron base 4, extends upward, and is arranged to match the magnetic ring 1. When installing the magnetic ring 1, the magnetic ring 1 is sleeved outside the annular flange 15. The material taking station, the transfer station, and the feeding station are horizontally aligned. It can be understood that the annular flange 15 is horizontally aligned with the support base 13 and is horizontally aligned with the topmost magnetic ring 1 of the initial group, ensuring that the three are at the same height position to avoid position deviation during synchronous grasping that may pinch hands.

[0043] In this embodiment, preferably, the gripper includes two relatively arranged gripper arms 16 and a double-acting cylinder 17 for driving the gripper arms 16 to approach or separate from each other. The gripper arms 16 are of an L-shaped structure and extend inward. A V-shaped groove 18 for clamping with the outside of the magnetic ring 1 is provided at the end of the gripper arm 16.

[0044] The two gripper arms 16 are relatively arranged and symmetrically distributed on both sides of the magnetic ring 1. The two gripper arms 16 are respectively connected to the two telescopic ends of the double-acting cylinder 17, which can drive the gripper arms 16 to horizontally expand and contract, so that the two gripper arms 16 approach or separate from each other to achieve the clamping function. The gripper arms 16 are of an L-shaped structure, and the clamping part is located at the end of the gripper arm 16 and extends toward the magnetic ring 1. The clamping part is of a V-shaped structure, and a V-shaped groove 18 with an opening facing the magnetic ring 1 is provided at its end. The arc surfaces are respectively located on the two side walls of the V-shaped groove 18 and match the shape of the outside of the magnetic ring 1. When the gripper arms 16 clamp the magnetic ring 1, the arc surfaces fit with the outside of the magnetic ring 1 to improve the clamping stability.

[0045] In this embodiment, preferably, a pressure head 19 is provided below the double-acting cylinder 17. The gripper arms 16 are symmetrically arranged on both sides of the pressure head 19. An accommodation cavity with an opening downward is provided inside the pressure head 19. The accommodation cavity is sleeved outside the top of the material rod 9, and the bottom of the pressure head 19 abuts against the top of the topmost magnetic ring 1.

[0046] The indenter 19 is located at the center of the two clamping arms 16 and extends vertically downward, being axially aligned with the magnetic ring 1. The indenter 19 is located below the double-acting cylinder 17 and has a cylindrical structure with an open bottom. The cavity is located inside the indenter 19 and has enough space to accommodate the end of the material rod 9. When the uppermost magnetic ring 1 is at the material-taking station, the clamping arms 16 move downward to the outside of the magnetic ring 1. At the same time, the bottom of the indenter 19 is horizontally abutted against the top of the magnetic ring 1, playing a limiting role to improve the positioning accuracy. The end of the material rod 9 protruding upward from the center of the magnetic ring 1 is inserted into the inside of the indenter 19 for avoidance. The inner diameter of the indenter 19 is larger than the inner diameter of the magnetic ring 1 to ensure that the end of the material rod 9 can be inserted into the inside of the indenter 19 and is isolated from the inner side of the indenter 19. The outer diameter of the indenter 19 is smaller than the outer diameter of the magnetic ring 1 to ensure that the indenter 19 abuts against the end face of the magnetic ring 1 and does not interfere with the clamping action of the two clamping arms 16 on both sides. The distance from the bottom of the indenter 19 to the bottom of the clamping arm 16 is equal to the thickness of the magnetic ring 1 to ensure that when the bottom of the indenter 19 abuts against the top of the magnetic ring 1, the clamping arms 16 are horizontally aligned with the magnetic ring 1.

[0047] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
