Description

Technical Field

[0001] This utility model relates to tooling, and in particular to a sticker applicator. Background Technology

[0002] Some existing motors, see Figure 10 The diagram illustrates a square motor in which the iron core 100' is too large to be enclosed by the outer casing 200', thus leaving the iron core 100' exposed outside the casing 200'. Therefore, during motor manufacturing, a sticker needs to be affixed to the exposed iron core 100' to provide waterproofing and rust prevention.

[0003] Current devices for attaching stickers to iron cores, such as those disclosed in Chinese patents with application numbers 201620016220.8 and 202210213935.2, simply involve rotating the iron core and the sticker. As a result, the sticker cannot adhere well to the surface of the iron core, especially when the iron core is not cylindrical, which makes it easier for the sticker to adhere unevenly and fail to perform its intended function.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a sticker applicator that can achieve automatic tracking and improve the sticker application effect.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a sticker applicator, comprising:

[0007] Base;

[0008] There are two side panels, which are respectively set on opposite sides of the base;

[0009] A sticker holder includes a spool rotatably supported on a base for holding sticker rolls; and

[0010] A sticker assembly for attaching a sticker to a part to be stickered, the sticker assembly being disposed between two side panels; characterized in that:

[0011] The sticker components include:

[0012] The rotating arm has two parts, each rotating arm corresponding to a side plate. The end of the rotating arm facing the scroll is rotatably connected to the corresponding side plate, and the end of the rotating arm away from the connection with the side plate is a free end. The free end of the rotating arm maintains a downward trend.

[0013] The first roller and the second roller are closely attached from bottom to top and positioned between two rotating arms. Each roller is rotatably connected to a rotating arm, with the connection position close to the free end of the rotating arm, so that the first roller tends to be in close contact with the surface of the part to be covered. The rotation axes of the roll, the rotating arms, and each roller are parallel to each other. The end of the sticker roll is divided into a stickerable part and a waste paper part by passing between the second roller and the first roller. The stickerable part bypasses the first roller and is in close contact with the surface of the part to be covered.

[0014] By setting a rotating arm with its free end pointing downwards, the roller can be positioned at the free end of the rotating arm, allowing the roller to remain in close contact with the surface of the part to be stickered. This is especially suitable for irregular or uneven object or product surfaces. The roller can follow the undulations of the surface of the part to be stickered and change its position accordingly, achieving automatic tracking (automatic matching of surface shape) and unobstructed sticker application, thus improving the sticker application effect.

[0015] To facilitate the handling of waste paper, the sticker assembly also includes a third roller that is abutted against the second roller. The third roller is positioned between the two rotating arms and is rotatably connected to the rotating arms. The connection position of the third roller to the rotating arms is close to the free end of the rotating arms, and the waste paper passes through the space between the second roller and the third roller.

[0016] To facilitate the rotation of each roller, a first transmission gear is fitted at each of the two ends of the first roller, a second transmission gear is fitted at each of the two ends of the second roller, and a third transmission gear is fitted at each of the two ends of the third roller. The second transmission gear meshes with the first transmission gear and the third transmission gear, respectively.

[0017] To increase the rotational speed of the rollers and improve the sticker application efficiency, the sticker application device also includes a transmission speed-increasing component. The transmission speed-increasing component includes two sets of gears, each set of gears corresponding to a side plate and a rotating arm. Each set of gears includes a first gear that rotates coaxially with the part to be stickered and a final gear installed in the rotating arm. The final gear rotates synchronously with the second roller, and the first gear and the final gear are connected by a transmission.

[0018] Furthermore, each gear set also includes a second gear rotatably disposed within the side plate. The sticker device also includes a rotating handle that rotates coaxially with the second gear. The rotating handle is located outside the side plate. The first gear and the second gear mesh, and the second gear is connected to the final gear via a transmission. Thus, the roller can be rotated by rotating the handle, improving operational convenience.

[0019] Preferably, to further improve the amplification speed, each gear set also includes a third gear, a fourth gear, and a fifth gear. The third gear and the fourth gear are also disposed in the side plate. The third gear meshes with the second gear. The fourth gear is coaxially disposed with the third gear and disposed on the side near the third gear and close to the rotating arm. The fifth gear meshes with the fourth gear and extends from the side plate into the adjacent rotating arm. The final stage gear is a sixth gear that meshes with the fifth gear.

[0020] To ensure the synchronization of the two gear sets, the two second gears are connected by a drive shaft.

[0021] To facilitate the installation of the part to be labeled, the first gear has a first mounting hole in the middle for the part to be labeled to pass through, the side plate has a corresponding second mounting hole for the part to be labeled to pass through, and the base has a corresponding mounting groove for the part to be labeled to pass through.

[0022] To increase the friction between the rollers so that the sticker roll keeps rotating, the surface of the second roller is provided with an anti-slip layer.

[0023] To facilitate adjustment and limit the axial position of the sticker roll and ensure that it is held in the desired position, the sticker holder also includes a limiting member for abutting against one axial end of the sticker roll. The limiting member is movable along the axial direction of the roll and can be fixed relative to the base.

[0024] Compared with the prior art, the advantages of this utility model are as follows: by setting a rotating arm with a downward trend at the free end, the roller can be set at the free end of the rotating arm, so that the roller can keep in close contact with the surface of the part to be stickered. It is especially suitable for irregular and uneven object or product surfaces. The roller can follow the undulations of the surface of the part to be stickered and change its position. It can achieve automatic tracking (automatic matching of surface shape) and perform sticker application without obstacles, thus improving the sticker application effect. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0037] See Figures 1 to 7 A sticker applicator includes a side plate 1, a base 2, a rotating handle 3, a sticker holder, a sticker assembly, and a transmission speed-increasing assembly.

[0038] Two side plates 1 are respectively disposed on opposite sides of the base 2. One or two rotating handles 3 are provided. When there is only one rotating handle 3, it is installed on the outer side of one of the side plates 1 (the side away from the base 2). When there are two rotating handles 3, each rotating handle 3 is installed on the outer side of one side plate 1. The rotating handles 3 are installed on the side of the side plate 1 away from the other side plate 1. A portion of the transmission speed-increasing assembly is installed inside the side plate 1, and the remaining portion is installed inside the sticker assembly. The sticker holder and the part to be stickered can be respectively installed to opposite ends of the base 2. The sticker holder includes a roller 41 and a limiting member 42. The roller 41 is rotatably supported on the base 2. The limiting member 42 is sleeved on the roller 41 and can move axially along the roller 41. The limiting member 42 includes a connecting part 421 and a limiting part 422, which can be integrally formed. The connecting part 421 is sleeved on the scroll 41 and can move along the axial direction of the scroll 41, and also extends into the base 2. The limiting part 422 is located at the end of the connecting part 421 away from the scroll 41. The base 2 is provided with a limiting shaft 22. The extending direction of the limiting shaft 22 is parallel to the axial direction of the scroll 41. The limiting part 422 can engage with the limiting shaft 22, thereby being fixed in the desired position.

[0039] The sticker assembly is located between two side plates 1 and includes a rotating arm 51, a bracket 52, a first roller 53, a second roller 54, and a third roller 55. The bracket 52 extends between the two side plates 1. Two rotating arms 51 are arranged on opposite sides of the bracket 52, each corresponding to one side plate 1. Each rotating arm 51 is rotatably mounted on its corresponding side plate 1, and the rotating arm 51 and the side plate 1 are rotatably connected, with the center of the connection point being the rotation center of the rotating arm 51. The axial direction of the sticker holder's spool 41 is parallel to the rotation axis of the rotating arm 51. Preferably, the end of the rotating arm 51 closest to the spool 41 of the sticker holder is rotatably connected to the side plate 1. Thus, the end of the rotating arm 51 furthest from the spool 41 (the end closest to the part to be stickered) is a free end. An elastic element such as a torsion spring can be provided at the connection between the rotating arm 51 and the side plate 1 to ensure that the free end of the rotating arm 51 always maintains a downward trend. Alternatively, as shown in the embodiment of this utility model, a spring 511 can be provided between the rotating arm 51 and the side plate 1, with both ends of the spring 511 abutting against the rotating arm 51 and the side plate 1 respectively. Spring seats can be provided on the rotating arm 51 and the side plate 1 to limit the position of the spring 511. This structure, which uses an elastic element to maintain a certain movement trend of a component, is existing technology.

[0040] The first roller 53, the second roller 54, and the third roller 55 are all disposed between the two rotating arms 51. The bracket 52 can cover at least part of the outer periphery of the rollers. The first roller 53, the second roller 54, and the third roller 55 can all rotate relative to the bracket 52. The first roller 53, the second roller 54, and the third roller 55 are rotatably connected to the rotating arms 51 from bottom to top, and the connection positions are close to the free ends of the rotating arms 51. That is, the connection points between each roller and the rotating arm 51, and the roller 41 are located on opposite sides of the rotation center of the rotating arm 51. Since the free ends of the rotating arms 51 always remain downward, each roller, especially the first roller 53, is kept in the lowest position to adhere tightly to the part to be covered. The first roller 53, the second roller 54, and the third roller 55 can adhere tightly to each other in sequence. To increase friction, the surface of the second roller 54 is provided with an anti-slip layer 542.

[0041] The transmission speed-increasing assembly includes a first gear 61, a second gear 62, a third gear 63, a fourth gear 64, a fifth gear 65, a sixth gear 66, and a drive shaft 67. The gear sets comprised of these gears are in two groups. In each group, some gears are rotatably supported within the side plate 1, while others are rotatably supported within a corresponding rotating arm 51. The drive shaft 67 connects the two groups of gears. The first gear 61 is located within the side plate 1, with a first mounting hole 611 in its center. A second mounting hole 12 is located at a corresponding position on the side plate 1, and a mounting groove 21 is located at a corresponding position on the base 2. Each mounting hole allows the component to be covered to pass through. The shape and size of the first mounting hole 611 can be determined according to the shape of the component to be covered, and the first gear 61 with a suitable first mounting hole 611 can be replaced when covering is required.

[0042] The second gear 62 is also located within the side plate 1 and meshes with the first gear 61. The rotating handle 3 is connected to the second gear 62 from outside the side plate 1, allowing both to rotate synchronously. The third gear 63 and the fourth gear 64 are also located within the side plate 1. The third gear 63 meshes with the second gear 62, and the fourth gear 64 is coaxially arranged with the third gear 63, positioned closer to the third gear 63 and near the rotating arm 51. The rotation axes of the third gear 63, the fourth gear 64, and the rotating arm 51 are the same. The fifth gear 65 meshes with the fourth gear 64, and the sixth gear 66 meshes with the fifth gear 65. The fifth gear 65 extends from the side plate 1 into the adjacent rotating arm 51, while the sixth gear 66 is rotatably mounted within the rotating arm 51. The fifth gear 65 can be a single gear of the same size, or it can be two coaxial, integrated gears of different sizes. During operation, the rotation axes of the first gear 61, the second gear 62, the third gear 63, and the fourth gear 64 remain unchanged, that is, their positions relative to the side plate 1 and the base 2 are fixed. However, the rotation axes of the fifth gear 65 and the sixth gear 66 can be changed. When the fourth gear 64 rotates, the fifth gear 65 can rotate around the outer circumference of the fourth gear 64, that is, it both rotates on its own axis and revolves around the fourth gear 64.

[0043] The end of the second roller 54 of the sticker assembly extends into the sixth gear 66, allowing both to rotate synchronously. The number and connection method of the gears between the second gear 62 and the sixth gear 66 can be changed as needed, as long as the final gear in the rotating arm 51 can be driven to rotate by the first gear 61 (second gear 62) located in the side plate 1, i.e., it is connected to the first gear 61 in a transmission manner. The drive shaft 67 is connected between the two second gears 62, enabling the gear sets on both sides to rotate synchronously.

[0044] For irregular or uneven object or product surfaces, the first roller 53 can change its position to follow the undulations of the surface of the part to be stickered by using the rotating arm 51 and the elastic element. When the rotating arm 51 rotates, the fifth gear 65 remains engaged with the fourth gear 64. When the surface of the part to be stickered pressed by the first roller 53 rises, the first roller 53 drives the entire sticker assembly to rise, and the rotating arm 51 rotates upward against the pressure of the elastic element, but the fifth gear 65 still remains engaged with the fourth gear 64, and the first roller 53 continues to follow the rotation of the part to be stickered to perform the stickering work. When the surface of the part to be stickered pressed by the first roller 53 falls, the first roller 53 drives the entire sticker assembly to fall, and the rotating arm 51 rotates downward against the pressure of the elastic element, but the fifth gear 65 still remains engaged with the fourth gear 64, and the first roller 53 continues to follow the rotation of the part to be stickered to perform the stickering work. Thus, the first roller 53 can automatically match the surface shape of the part to be stickered, which is constantly undulating, and perform the stickering work without obstacles.

[0045] The first roller 53 has a first transmission gear 531 fitted at each of its two ends, the second roller 54 has a second transmission gear 541 fitted at each of its two ends, and the third roller 55 has a third transmission gear 551 fitted at each of its two ends. The second transmission gear 541 meshes with the first transmission gear 531 and the third transmission gear 551, respectively. Thus, when the second roller 54 is driven to rotate by the transmission speed-increasing component, it can drive the first roller 53 and the third roller 55 to rotate.

[0046] The rotation axes of the rollers, rotating arm 51, and gears in the gear set are parallel to each other or are on the same axis. Through the aforementioned transmission speed-increasing component, the rotational speed of the part to be stickered is increased many times over, and then converted into rapid rotational motion of the rollers in the sticker assembly.

[0047] See Figure 8 and Figure 9When the sticker applicator is working, firstly, the rolled sticker roll 20 is fitted onto the outer periphery of the roll 41 of the sticker holder. The sliding limit member 42 is then used to fix the position of the sticker roll 20 (the limit member 42 is located at one axial end of the sticker roll 20), and then it is locked against the limit shaft 22 of the base 2, preventing the sticker roll 20 from moving axially and affecting normal operation. Then, one end of the sticker roll 20 is pulled out and passed between the second roller 54 and the first roller 53. The part that passes through is divided into two layers (which can be manually torn apart): the lower adhesive portion 201 and the upper adhesive portion 201. The waste paper portion 202 and the adhesive portion 201 are wound downwards around the surface of the first roller 53. The waste paper portion 202 passes between the third roller 55 and the second roller 54 and is led to one side of the reel 41 for disposal. Then, the bracket 52 is pulled, causing the entire sticker assembly to be lifted upwards against the force of the elastic element. The part to be stickered (taking the motor 10 as an example in this embodiment) passes through the mounting positions of the side plate 1, the base 2, and the first gear 61 and is mounted rotatably relative to the base 2. The motor 10 and the first gear 61 rotate synchronously, adjusting the first... The adhesive portion 201 of the sticker roll 20 on the roller 53 is adhered to the surface of the motor 10 and made flat. The bracket 52 is lowered, and due to the action of the rotating arm 51, the first roller 53 can remain in close contact with the surface of the motor 10. Thus, the adhesive portion 201 of the sticker roll 20 can remain in close contact with the surface of the iron core 100 of the motor 10 and can be adhered to the surface of the iron core 100. Finally, the motor 10 is rotated, or the rotating handle 3 is turned to drive the motor 10 to rotate. The rotational motion is transmitted to the sticker assembly through a series of gears in the transmission speed-increasing component. Each roller has a first roller 53 that rolls on the surface of the iron core 100 of the motor 10, sticking the stickable portion 201 of the sticker roll 20 to the surface of the iron core 100 of the motor 10. The stickable portion 201 is continuously pulled out from the sticker roll 20 and stuck to the surface of the iron core 100 of the motor 10 by the close rolling of the second roller 54 and the first roller 53 (the upper surface of the roller 2 is equipped with a non-slip material with high friction). The third roller 55 and the second roller 54 roll together to continuously roll out and send away the waste paper portion 202.

[0048] This achieves the process of automatically feeding paper, automatically applying paper, and automatically removing waste paper as the part to be stickered rotates.
