Description

Technical Field

[0001] The utility model belongs to the technical field of automatic caster assembly equipment, in particular to a wheel cover assembly machine. Background Art

[0002] Casters are widely used in everyday applications, such as luggage, to enable the movement of objects fitted with casters. Typically, a caster consists of a wheel and a wheel cover. The wheel cover snaps onto the outside of the wheel using a snap-fit ​​mechanism, serving as a decorative element. To improve assembly efficiency and reduce labor, wheel cover assembly machines enable the assembly of wheel covers onto wheels in a mechanized, automated, or semi-automated manner.

[0003] For example, a Chinese utility model patent with publication number CN220178584U and publication date December 15, 2023 discloses an automatic assembly device for caster dust covers, including a workbench, and the caster dust cover automatic assembly device also includes a caster positioning mechanism, a left dust cover positioning mechanism, a right dust cover positioning mechanism, a left dust cover pushing mechanism, and a right dust cover pushing mechanism arranged on the workbench; during assembly, the left dust cover and the right dust cover are respectively located on the left dust cover positioning mechanism and the right dust cover positioning mechanism, and the caster is located on the caster positioning mechanism, and then the left dust cover pushing mechanism installs the left dust cover on the left dust cover positioning mechanism to the left side of the caster, and the right dust cover pushing mechanism installs the right dust cover on the right dust cover positioning mechanism to the right side of the caster.

[0004] In the above-mentioned prior art, the left dust cover propulsion mechanism and the right dust cover propulsion mechanism both use a mounting base, a propulsion cylinder mounted on the mounting base, and a push rod mounted at the telescopic end of the propulsion cylinder. Such a left dust cover propulsion mechanism and the right dust cover propulsion mechanism can only be assembled by moving the wheel cover in a horizontal direction toward the wheel.

[0005] In another caster structure, the wheel and the wheel cover are connected by a snap-fit ​​connection. Specifically, the wheel cover is provided with a protruding snap-fit ​​foot, and the wheel is provided with a snap-fit ​​socket that matches the snap-fit ​​foot. During assembly, the snap-fit ​​foot needs to be aligned with the position of the snap-fit ​​socket and the snap-fit ​​foot needs to be inserted into the snap-fit ​​socket. The snap-fit ​​foot is used to hook the inner edge of the snap-fit ​​socket to connect the wheel cover and the wheel together.

[0006] Obviously, during the assembly operation, the relative positions of the wheel and the wheel cover in the circumferential direction are arbitrary in the wheel cover assembly machine in the prior art, and the machine does not have the function of aligning the positions of the clamping feet and the clamping mouths, and cannot be used to assemble the wheel cover and wheel with a snap connection.

[0035] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] In the description of this application, it should be understood that the terms "upper" and "lower" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0037] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0038] The utility model discloses a wheel cover assembly machine, comprising a caster main body channel 1, a wheel pressing plate mechanism 2, and a cover pressing mechanism 3. This wheel cover assembly machine is used to assemble a caster wheel cover and wheel. In the utility model, the caster comprises a mounting seat 201, a wheel 202, a core shaft (not shown), and a wheel cover 203. Two wheels are mounted on the core shaft, with the mounting seat positioned between the two wheels. The wheels are provided with a bayonet 205, and the wheel cover is provided with a clamping foot 206. The clamping foot and the bayonet are adapted to form a snap-fit ​​connection between the wheel cover and the wheel.

[0039] In the present invention, the caster main body material channel 1 is provided with a material channel cavity 4, and the material channel cavity 4 is for the caster main body to be placed. The caster main body material channel 1 is provided with an assembly station 5, and the assembly station 5 is the position in the material channel cavity 4 where the caster main body receives the wheel cover for assembly. A feed hole 6 is provided on the caster main body material channel 1 at the position of the assembly station 5. The inner diameter of the feed hole 6 is slightly larger than the outer diameter of the wheel cover, so that the wheel cover can pass through the feed hole 6 and be assembled with the wheel. In this practical example, the feed hole 6 is concentric with the wheel on the assembly station 5. It should be pointed out that in this embodiment, the caster main body includes a mounting seat, a wheel and a core shaft. The mounting seat, the wheel and the core shaft need to be assembled together in advance, and then the wheel cover assembly machine of the present invention is used to assemble the wheel cover to the wheel of the caster main body. In the present invention, there are two wheels, and accordingly, a wheel cover needs to be assembled for each wheel. Therefore, a material passage hole 6 is provided on each side of the caster main body material channel, and correspondingly, a capping mechanism 3 is provided on each side of the caster main body material channel 1. Of course, if only one of the wheels needs to be assembled with a wheel cover, the wheel cover assembly machine can also be equipped with only one capping mechanism 3.

[0040] In another embodiment, for a caster structure with a non-hidden spindle, the wheel and the wheel cover can be assembled first, and then subsequently assembled to form the caster. In this way, the wheel can be defined as the caster body. Basically, the caster body material channel should also be designed to be a structure suitable for the wheel for placement of the wheel.

[0041] As shown in the figure, the caster main body channel 1 includes a first mold plate 7 and a second mold plate 8. The first mold plate 7 and the second mold plate 8 are arranged opposite to each other, and the inner lower end of the first mold plate 7 and the inner lower end of the second mold plate 8 are both provided with a protrusion 9. There is a distance between the protrusion 9 of the first mold plate 7 and the protrusion 9 of the second mold plate 8. Among them, the protrusion 9 is for the wheel to rest, and the position between the two protrusions 9 is used to receive the connecting shaft 204 of the mounting seat. The upper space of the protrusion 9 is larger than the outer diameter of the wheel, and the space between the two protrusions 9 is slightly larger than the outer diameter of the connecting shaft of the mounting seat. In this embodiment, the upper space of the protrusion 9 and the space between the two protrusions 9 are used to construct the channel cavity 4. As a result, the caster body can slide in the caster main body channel 1. When the wheel cover assembly machine performs assembly operations, the caster main body channel 1 is used to convey the caster body.

[0042] The distance between the first and second molded plates 7, 8 is adjustable via an adjustment mechanism 10. As shown in the figure, the adjustment mechanism 10 comprises an adjustment rail 11 fixed to a top plate 14. Adjustment sliders 12 are fixed to both the first and second molded plates 7, 8. The adjustment sliders 12 and the adjustment rail 11 form a guide rail pair. An adjustment screw 13 passes through the first and second molded plates 7, 8. A first adjustment nut for securing the first molded plate 7 and a second adjustment nut for securing the second molded plate 8 are threadedly connected to the adjustment screw 13. Typically, two first adjustment nuts are provided, one on each side of the first molded plate 7, to clamp and secure it. Similarly, two second adjustment nuts are provided, one on each side of the second molded plate 8, to clamp and secure it. Alternatively, the first and second molded plates can be secured by a threaded hole in the first molded plate 7 that mates with the adjustment screw 13, which is then secured using a first adjustment nut. Furthermore, the second molded plate 8 has a threaded hole in the second molded plate 8 that mates with the adjustment screw 13, which is then secured using a second adjustment nut.

[0043] In the aforementioned adjustment mechanism 10, the adjustment slider 12 and the adjustment guide rail 11 are used to constrain the first mold plate 7 and the second mold plate 8 to translate away from or toward each other, thereby preventing height misalignment of the first mold plate 7 and the second mold plate 8 after the distance is adjusted. This also reduces the precision requirements for the holes in the first mold plate 7 and the second mold plate 8 through which the adjustment screws 13 pass. The first mold plate 7 is fixed by the adjustment screw 13 and the first adjustment nut, and the second mold plate 8 is fixed by the adjustment screw 13 and the second adjustment nut.

[0044] It should be noted that when the caster main body channel 1 is designed not to have the distance adjustment function, the adjustment mechanism 10 may not be used, and the first mold plate 7 and the second mold plate 8 are fixed on the frame.

[0045] As shown in the figure, the caster body material channel 1 is arranged in an inclined manner. With this structure, the caster body can slide onto the assembly station 5 by virtue of its gravity.

[0046] To clearly illustrate the principle of the related structure, Figure 8 The structure of the first template 7 is not shown. Figure 8As shown, the caster main body material channel 1 is provided with a first material stopper 15 and a second material stopper 16. In this embodiment, the first material stopper 15 and the second material stopper 16 both include a material stopper cylinder 17 and a material stopper rod 18. The piston rod of the material stopper cylinder 17 is extended and retracted to enable the material stopper rod 18 to have a position for blocking the caster main body and a position for releasing the blockage of the caster main body. In specific applications, when the first material stopper 15 is in operation, the caster main body can be stopped at the position of the assembly station 5, that is, the wheel is relatively opposite to the feed hole 6. After being released, the assembled caster slides out of the caster main body material channel 1. Before the first material stopper 15 releases the blockage of the caster main body, the second material stopper 16 is in a blocking state; when the first material stopper 15 is in a blocking state, the second material stopper 16 releases the blocking state. This process allows multiple caster main bodies on the caster main body material channel 1 to enter the assembly station 5 one by one.

[0047] The pressure wheel plate mechanism 2 has a first position on the assembly station 5 for pressing against the wheel of the caster body to fix it on the caster body material channel 1, and a second position separated from the wheel. In this embodiment, the pressure wheel plate mechanism 2 includes a fixed second linear reciprocating motion mechanism 19, such as a cylinder, etc. A pressure plate 20 is fixed on the output end of the second linear reciprocating motion mechanism 19, and two pressure parts 21 are provided on the pressure plate 20, one pressure part 21 corresponding to one wheel, and an expansion opening 22 is provided on the pressure part 21, and the expansion opening 22 is used to contact the wheel. In this embodiment, viewed from the side of the pressure part 21, the expansion opening 22 is an angled structure. Of course, as another embodiment, the expansion opening 22 can also adopt an arc-shaped structure. Since the expansion opening 22 has the function of centering, the caster body can be accurately positioned on the assembly station 5 to receive the wheel cover assembly. In this embodiment, since the wheel is supported on the extension 9, the caster body can be positioned on the assembly station 5 by applying pressure to the wheel through a set of pressure plate mechanisms 2. In another embodiment, two sets of pressure plate mechanisms 2 can be used, distributed on opposite sides of the wheel in the circumferential direction, to position the caster body on the assembly station 5.

[0048] See also Figure 2 、 Figure 3 、 Figure 4, a capping mechanism 3 is used to push the wheel cover from the outside of the feed hole 6 to the wheel so that the wheel cover and the wheel are assembled. In the utility model, the capping mechanism 3 includes a base 23, on which is provided a workbench 24 that slides perpendicularly to the direction of the caster main body material channel 1. Usually, the workbench 24 is mounted on the base 23 through a guide rail pair 27. The workbench 24 can move in the direction close to the feed hole 6 and away from the feed hole 6. A first motor 25 is provided on the workbench 24. Usually, the first motor 25 adopts a stepper motor or a servo motor. Of course, other types of motors can also be used in some embodiments. A push rod 26 is provided at the output end of the first motor 25. In this example, the push rod 26 is made of polyurethane material, which has a certain friction force and will not scratch the wheel cover, thereby ensuring the integrity of the wheel cover after assembly. Usually, the push rod 26 is connected to the output shaft of the first motor 25 through a coupling. The workbench 24 is connected to the output end of a first linear reciprocating mechanism 35, typically a pneumatic cylinder. As shown in the figure, the cover channel 28 is constructed using a rear plate 32, a front plate 33, and side plates 34. Typically, the latching pins on the wheel cover extend from the space between the two front plates 33. The lower end of the cover channel 28, which provides the wheel cover, connects to a guide device 30 having a guide channel 29. In this embodiment, the inner diameter of the guide channel 29 is slightly larger than the outer diameter of the wheel cover, allowing the wheel cover to be smoothly pushed within the guide channel 29 by the pusher rod 26. The guide device 30 is located to the side of the caster main channel 1, with one end of the guide channel 29 facing the feed hole 6. The other end of the guide channel 29 faces the pusher rod 26, which passes through the guide channel 29. The pusher rod 26 initially positions itself outside the receiving station 31 of the guide channel 29. It should be noted that the initial position of the pusher rod 26 is outside the material receiving station 31. In terms of the position of the pusher rod 26 relative to the guide device 30, the initial position of the end of the pusher rod 26 can be either inside or outside the guide device 30. To facilitate assembly of the wheel cover assembly machine, the initial position of the end of the pusher rod 26 is outside the guide device 30.

[0049] In the present invention, due to the structure of the first motor 25 and the push rod 26, the wheel cover can be driven to rotate when it initially contacts the wheel, thereby the wheel cover can be rotated to a position where its clamping foot is relative to the buckle on the wheel. At the same time, the workbench 24 for mounting the push rod 26 and the first motor 25 is acted upon by the output end of the first linear reciprocating motion mechanism 35, and the wheel cover continues to move toward the wheel, so that the clamping foot on the wheel cover is completely engaged with the buckle on the wheel. Obviously, the wheel cover assembly machine of the present invention realizes the assembly of the wheel cover and the wheel with a buckle connection by connecting the push rod 26 to the output end of the first motor 25, and the first motor 25 and the push rod 26 as a whole can be moved by the first linear reciprocating motion mechanism 35.

[0050] In this embodiment, the first linear reciprocating motion mechanism 35 is a first pneumatic cylinder, and the wheel cover assembly machine further includes a first damping mechanism 36. The workbench 24 is connected to the output end of the first pneumatic cylinder via the first damping mechanism 36. The first damping mechanism 36 damps and contracts when the output end of the first cylinder pushes the workbench 24 toward the caster body material channel 1. As shown in the figure, the first damping mechanism 36 includes a first guide rod 37 fixed to the workbench 24. A slidable connecting plate 38 is mounted on the first guide rod 37. The connecting plate 38 is connected to the output end of the first pneumatic cylinder. A first spring is disposed between the workbench 24 and the connecting plate 38. Typically, the first spring is also mounted on the first guide rod 37. In specific applications, when the push rod 26 is pushed toward the main material channel 1 of the caster, that is, when the foot of the wheel cover contacts the non-snag position on the wheel, the piston rod of the first cylinder continues to extend. Since the foot is against the wheel, the first spring is compressed at this time, and the piston rod of the first cylinder moves with the connecting plate 38 on the first guide rod 37, while the workbench 24 is not pushed forward, forming a damping contraction. During this period, the first motor 25 drives the push rod 26 to rotate, and there is a certain friction between the push rod 6 and the wheel cover, so that the push rod 6 drives the wheel cover to rotate circumferentially until the foot and the buckle are relative. At this time, the push rod 26 pushes the wheel cover further toward the wheel, so that the wheel cover and the wheel are engaged. It can be understood that due to the damping contraction of the first damping mechanism 36, the push rod 26 has sufficient time to drive the wheel cover to rotate so that the foot on the wheel cover is aligned with the buckle of the wheel, thereby avoiding the wheel cover being further pushed when the foot is not aligned with the buckle, thereby avoiding damage to the foot during assembly.

[0051] Similar to the above-mentioned first damping mechanism 36 , the first guide rod 37 can be slidably connected to the workbench 24 , and the connecting plate 38 is fixedly connected or slidably connected to the first guide rod 37 .

[0052] The capping mechanism 3 further comprises a first buffer 39 which acts as a damper when the workbench 24 moves away from the caster main body channel 1. Typically, the first buffer 39 acts as a damper for a first guide rod 37 fixed to the workbench 24.

[0053] In this embodiment, the guide device 30 is provided with a transversely extending assembly cavity 40, which is connected to the guide channel 29. A movable anti-roll block 41 is installed in the assembly cavity 40. Specifically, the inner diameter of the assembly cavity 40 is slightly larger than the outer diameter of the anti-roll block 41, forming a clearance fit between the two. An inclined surface 42 is provided on the end of the anti-roll block 41 adjacent to the guide channel 29. The inclined surface 42 faces the material receiving station 31 of the guide channel 29. In this embodiment, the inclined surface 42 forms a predetermined angle with respect to the axial direction of the guide channel 29. The anti-roll block 41 can extend from the assembly cavity 40 and retract into it. In this embodiment, a compression spring is provided on the end of the anti-roll block 41 away from the inclined surface 42. The compression spring forces the anti-roll block 41 to extend from the assembly cavity 40. When the anti-roll block 41 extends from the assembly cavity 40, the inclined surface 42 can rest against the inner side of the wheel cover on the material receiving station 31. When the push rod 26 moves toward the caster main body channel 1, the wheel cover acts on the inclined surface 42, causing the anti-tilt block 41 to retract into the assembly cavity 40. In this way, after the anti-tilt block 41 is provided, it can be ensured that after the wheel cover falls from the cover channel 28 into the receiving station 31 and before it is pushed toward the caster main body channel 1 by the push rod 26, the cover is acted upon by the anti-tilt block 41 and will not cause the wheel cover to tilt toward the caster main body channel 1, thereby ensuring that the wheel cover can be pushed toward the wheel by the push rod 26 in an upright state.

[0054] The guide channel 29 is provided with an external stopper 50 for the outer side of the wheel cover at the receiving station 31 to rest against. The external stopper 50 has a through-hole 51 for the push rod 26 to pass through. Similarly, due to the structure of the external stopper 50, the cover is restrained by the external stopper 50 and does not cause the wheel cover to tip away from the main caster material channel 1. It should be noted that the external stopper 50 does not need to be provided, and the end of the push rod 26 can also be used to prevent the wheel cover from tipping away from the main caster material channel 1.

[0055] In one embodiment, the outer limiting portion 50 includes a protruding edge 52 provided on the base 43, the protruding edge 52 radially protrudes relative to the arc groove 44, a first arc portion 53 is provided on the protruding edge 52, and a second arc portion 54 is provided on the rear plate 32 of the cover material channel 28. The first arc portion 53 and the second arc portion 54 are opposite to each other to form the through hole 51.

[0056] In this embodiment, the guide device 30 includes a base 43 having an arcuate groove 44 disposed thereon. A first clamping jaw 45 and a second clamping jaw 46 are disposed above the base 43. In this embodiment, the first clamping jaw 45 and the second clamping jaw 46 are symmetrically structured. The first and second clamping jaws 45 and 46 are each connected to a finger cylinder 47, which allows the first and second clamping jaws 45 and 46 to move toward and away from each other. The first and second clamping jaws 45 and 46 each include a caster body 48 having a first arcuate surface 49. The first arcuate surface 49 of the first clamping jaw 45, the first arcuate surface 49 of the second clamping jaw 46, and the arcuate groove 44 form the guide channel 29. In a specific application, the finger cylinder 47 is controlled to bring the first clamping jaw 45 and the second clamping jaw 46 into a state of approaching each other, and the wheel cover is pushed by the push rod 26 into the guide channel 29 constructed by the first curved surface 49 on the first clamping jaw 45, the first curved surface 49 on the second clamping jaw 46, and the curved surface groove 44. When the first clamping jaw 45 and the second clamping jaw 46 move away from each other, the first curved surface 49 on the first clamping jaw 45 and the first curved surface 49 on the second clamping jaw 46 are separated by a certain distance. If the wheel cover falls, it can be removed from the position between the first clamping jaw 45 and the second clamping jaw 46. In the structure of this guide device, the assembly cavity 40 is provided on the base 43.

[0057] Typically, both the first and second jaws 45, 46 have a panel 55 secured to the caster body 48. The panel 55 has a ridge 56 positioned to align with the cavity of the cover channel 28. The cavity of the cover channel 28 is designed to receive the wheel cover. Below the ridge 56, the panel 55 has a second curved surface 57. Typically, the second curved surface 57 is aligned with the first curved surface 49. The curved groove 44 extends below the second curved surface 57 on the first jaw 45 and below the second curved surface 57 on the second jaw 46. Lower notches 58 are provided on either side of the lower end of the cover channel 28 for inserting the panel 55. By adopting the above structure, when the first clamping jaw 45 and the second clamping jaw 46 approach each other, the position of the ridge 56 corresponds to the material cavity of the cover material channel 28 and is inserted into the material cavity. In this way, the ridge 56 blocks the wheel cover of the material cavity, preventing the wheel cover in the material cavity from contacting the pusher rod 26 during the movement of the pusher rod 26 in the guide channel 29. When the first clamping jaw 45 and the second clamping jaw 46 move away from each other, the ridge 56 releases the blockage of the wheel cover in the material cavity, and the wheel cover falls to the material receiving station 31 in the guide channel 29; when the first clamping jaw 45 and the second clamping jaw 46 approach each other again, the second curved surface 57 on the first clamping jaw 45 and the second curved surface 57 on the second clamping jaw 46 can make the wheel cover completely contact the curved surface groove 44, and then the guide channel 29 guides the wheel cover forward.

[0058] As shown in the figure, a groove 59 is defined between the panel 55 and the first curved surface 49. The groove 59 is adapted to receive the front plate 33 of the cover channel 28. The lower end of the front plate 33 abuts against the base 43, and a third curved surface 60 is defined on the inner side of the lower end of the front plate 33, aligned with the first curved surface 49. Because the front plate 33 abuts against the base 43, the front plate 33 can provide a certain degree of guidance to the wheel cover in the material cavity when it falls onto the curved groove 44.

[0059] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
