Description

Technical Field

[0001] This application relates to the field of label pasting technology, and in particular to a label pasting mechanism and label pasting device. Background Technology

[0002] In fields such as automated packaging, electronic assembly, and product labeling, high-precision and high-efficiency label application to product surfaces is a common and crucial process. Traditional labeling mechanisms typically rely on robotic arms or cylinders to drive a label suction head along a straight path to press against the product surface to complete the labeling. However, when the product's posture and angle change, this rigid contact method is prone to causing labels to not adhere properly, creating air bubbles, wrinkles, or even damaging the product or label. Furthermore, the resetting accuracy is not high, and after prolonged use, the original labeling accuracy cannot be maintained. Because the product's posture cannot be guaranteed to remain constant during each labeling process, the posture and angle of the labeling surface are random. Existing technologies have introduced floating buffer structures, such as springs or elastomers placed between the label suction plate and the transmission unit. While these structures provide some buffering effect and allow for slight displacement of the label suction plate, they have significant drawbacks. For example, the floating is mostly unidirectional or linear, failing to achieve true omnidirectional adaptive deflection, resulting in poor adhesion. Furthermore, the elastic structure cannot achieve precise reset. After labeling and pressure removal, the label suction plate resets due to spring force, but its final reset posture is uncertain, failing to guarantee consistency in the initial state before each labeling, severely impacting labeling accuracy and repeatability. Moreover, excessive deflection angles pose a risk of overload damage. Utility Model Content

[0022] This application provides a labeling mechanism 100 and a labeling device.

[0023] First, let's introduce the labeling mechanism 100 of this application. The labeling mechanism 100 includes a first plate 110, a floating connection structure 120, a transmission structure, a second plate 140, and a guide structure. The following will describe these components in conjunction with... Figures 1 to 4 The labeling organization 100 will be introduced.

[0024] Combination Figure 1 As shown, for the first plate 110, one side of the first plate 110 is used to absorb and affix labels; The floating connection structure 120 includes an elastic member 121 and a first connecting part 122. One end of the elastic member 121 is connected to one end of the first connecting part 122, and the other end of the first connecting part 122 is connected to the other side of the first plate 110. The elastic member 121 is used to contract when the first plate 110 is compressed and to reset the first plate 110. The second plate 140 is provided with a first hole 141, and the first connecting part 122 passes through the first hole 141; The transmission structure includes a second connecting part 131 and a transmission part 130. One end of the second connecting part 131 is connected to the second plate 140, and the other end of the second connecting part 131 is connected to the transmission part 130. The second connecting part 131 is used to fix the second plate 140 to the transmission part 130. The other end of the elastic member 121 is connected to the transmission part 130. The transmission part 130 is used to drive the first plate 110 to move closer to or away from the product to be labeled. A guide structure is disposed between the first connecting part 122 and the second plate 140. The guide structure is used to assist the first plate 110 in resetting.

[0025] Combination Figure 1As shown, the first plate 110 is a label suction plate, one side of which is used to suction labels and affix them to the product to be labeled, and the other side is connected to the floating connection structure 120. The side of the first plate 110 used for suction labels is provided with suction cups, adhesion structures, suction holes, vacuum suction holes, etc. The transmission part 130 is connected to the other end of the floating connection structure 120, and the other side of the transmission part 130 is connected to the output end of the drive mechanism. The output end of the drive mechanism is connected to the transmission part 130, so that the transmission part 130 can drive the first plate 110 and the floating connection structure 120 to move closer to or further away from the product to be labeled.

[0026] The elastic element 121 of the floating connection structure 120 can be a structure that can be compressed under pressure and reset when not compressed, such as an elastic body such as a rubber column, silicone column, or spring. When needed, it can be processed into columnar or block-shaped structures. When the transmission part 130 drives the first plate 110 and the floating connection structure 120 to approach the product to be labeled, the first plate is subjected to pressure, and the elastic element 121 is compressed or simultaneously undergoes shear deformation, allowing the first plate 110 to adapt to the surface of the product to be labeled and to deflect in multiple directions. After the pressure is removed, it returns to its original shape due to the elasticity of the elastic element 121 itself, and the first plate 110 resets.

[0027] The first connecting part 122 can be a columnar, cylindrical, rod-shaped or other structure.

[0028] Combination Figure 2 , Figure 4 As shown, the second plate 140 is provided with a first hole 141, and the first connecting part 122 is movably inserted through the first hole 141. By setting the distance between the outer wall of the first connecting part 122 and the inner wall of the first hole 141, the deflection angle of the first plate 110 during the shrinking and resetting process can be adjusted.

[0029] The transmission part 130 can be a cylinder or a robotic arm or other component that can drive the first plate 110 to approach or move away from the product to be labeled. The structure connected to the output end of the transmission part 130 has space for installing the second mounting part. For example, the output end of the transmission part 130 is connected to a plate, block or other structure. The second connecting part 131 is connected between the second plate 140 and the transmission part 130, so that the second plate 140, the second connecting part 131 and the transmission part 130 are a whole, providing a stable motion basis for the extension and retraction of the floating connection structure 120.

[0030] The second connecting part 131 can be a columnar, cylindrical, or rod-shaped structure that can stably connect the second plate 140 and the transmission part 130. The output end of the transmission part 130 is connected to a structure with a mounting hole 133 for mounting the second connecting part 131. The second connecting part 131 can be inserted into or screwed into the mounting hole 133. It is understood that the second plate 140 can also be provided with a mounting hole 133 for connecting the second connecting part 131.

[0031] In one embodiment, the transmission unit 130 drives the first plate 110, the floating connection structure 120, the second plate 140, and the second connecting part 131 to approach the product to be labeled. After the label on the first plate 110 contacts the product to be labeled, the transmission unit 130 continues to approach the product. The first plate 110 is subjected to pressure, which is transmitted to the first connecting part 122, thereby causing the elastic member 121 to contract. If the labeling surface of the product to be labeled is a labeling surface with random posture and angle, the first plate 110 and the first connecting part 122 will deflect in multiple directions within the first hole 141, deviating from the center line of the first hole 141. After the labeling is completed, the transmission unit 130 drives the first plate 110 away from the product, the elastic member 121 releases its elastic force to reset, the guide structure assists the first plate 110 to reset, and assists the first connecting part 122 to align with the center line of the first hole 141, thereby accurately guiding the first connecting part 122 and the first plate 110 back to the state before labeling, preparing for the next labeling.

[0032] A guide structure is disposed between the first connecting portion 122 and the second plate 140, and the guide structure is used to assist the first plate 110 in resetting. For example, a protruding portion is provided at the end of the first connecting portion 122 away from the first plate 110, and a recessed portion is provided on the side of the first hole 141 facing the transmission portion 130 to cooperate with the protrusion. The recessed portion is provided with a guide bevel or a spherical end to ensure that the first connecting portion 122 can pass through the recessed portion of the structure and be smoothly guided in when resetting. Alternatively, in the non-working state, a magnetic attraction structure is provided at the part of the first connecting portion 122 that contacts the first hole 141. When the first connecting portion 122 resets, the magnetic attraction structure can guide the first connecting portion 122 to drive the first plate 110 to reset.

[0033] In the labeling mechanism 100 of this application, the first plate 110 and the transmission part 130 are connected by a floating connection structure 120. The first plate 110 can deflect in multiple directions to adapt to the labeling surface with random postures and angles. The second connecting part 131 fixes the transmission part 130 and the second plate 140 to ensure stability. Through the guide structure provided between the first connecting part 122 and the second plate 140, working in conjunction with the restoring force of the elastic member 121, the labeling mechanism 100 is applied to labeling surfaces with random postures and angles, and has high labeling accuracy and high repeatability.

[0034] Specifically, a protrusion 1221 is provided at one end of the first connecting part 122 connected to the elastic member 121. The protrusion 1221 faces the first plate 110 and includes a spherical structure. A recess is provided on the side of the first hole 141 facing away from the first plate 110. The recess can fit with the spherical structure. The protrusion 1221 and the recess cooperate to form a guide structure.

[0035] A protrusion 1221 is provided at the end of the first connecting part 122 that contacts the first hole 141. A recess is provided in the first hole 141 to cooperate with the protrusion 1221. An elastic member 121 is provided between the first connecting part 122 and the transmission part 130. The protrusion 1221 can prevent the distance between the first plate 110 and the transmission part 130 from being larger than the distance before the elastic member 121 retracts when the elastic member 121 is reset, thus protecting the labeling mechanism 100 and the product to be labeled. The first plate 110 deflects around the universal ball joint formed by the protrusion 1221 and the recess, and the label adheres to the product surface. After the label is adhered, the transmission part 130 drives the first plate 110 away from the product, and the elastic element 121 releases its elastic force to reset, pushing the protrusion 1221 toward the recess. The spherical structure of the recess guides the protrusion 1221, thereby accurately guiding the first connecting part 122 and the first plate 110 back to their state before labeling, preparing for the next labeling.

[0036] The protrusion 1221 and the recess are both spherical. The protrusion 1221 is at least partially embedded in and fits against the recess, forming a universal ball joint. During the process of the first plate 110 being compressed and retracting towards the transmission part 130, the universal ball joint can support the stable multi-directional deflection of the first plate 110. At the same time, the fit between the protrusion 1221 and the recess reduces shaking and noise. When the elastic element 121 is compressed and retracts, the spherical structure of the recess provides guidance for the protrusion 1221 during the reset process, so as to achieve precise reset. The first connecting part 122 is movably inserted through the first hole 141, and the first hole 141 is provided with a recess facing the first plate 110. The protrusion 1221 is adapted to the recess. In the non-working state, at least part of the protrusion 1221 is embedded in and fits against the recess, which improves the connection stability between the first connecting part 122 and the second plate 140.

[0037] In some embodiments, a plurality of floating connection structures 120 are provided between the first plate 110 and the transmission part 130, and correspondingly, a plurality of first holes 141 are provided on the second plate 140. Providing a plurality of floating connection structures 120 makes the contraction and reset process of the first plate 110 more stable. When the first plate 110 is attached to a labeling surface with random postures and angles, the plurality of elastic elements 121 contract unevenly. During the reset process, the elastic elements 121 apply force to the first connecting parts 122 connected to them. The first connecting parts 122 with smaller deflection angles first apply a reset force to the first plate 110, and the first plate 110 applies a reset force to other first connecting parts 122 with larger deflection angles. While the plurality of first connecting parts 122 reset through the elastic elements 121 and the recessed portion, they also transmit force through the first plate 110, achieving rapid reset.

[0038] Furthermore, a second connecting portion 131 is provided at the middle position of the second plate 140, and first holes 141 are evenly distributed around the second connecting portion 131. The first connecting portion 122 passes through the first hole 141, which ensures that the first plate 110 has a stable posture during deflection and reset, and does not cause uncontrollable shaking, thus improving labeling accuracy and repeatability. Alternatively, multiple second connecting portions 131 are evenly distributed along the edge of the second plate 140, and the first holes 141 are located inside the structure enclosed by the second connecting portions 131. The first connecting portion 122 passes through the first hole 141, which also improves labeling accuracy and repeatability.

[0039] Specifically, a first hole 141 and a second connecting portion 131 are adjacently distributed on the second plate 140. The elastic member 121 and the second connecting portion 131 are alternately or adjacently distributed between the second plate 140 and the transmission portion 130. The elastic member 121 and the second connecting portion 131, which are adjacently distributed between the second plate 140 and the transmission portion 130, do not interfere with each other functionally, resulting in a more stable structure. This optimizes the use of space between the second plate 140 and the transmission portion 130, leading to a compact structure.

[0040] Specifically, in combination Figure 1 As shown, the second plate 140 is provided with three first holes 141 and three second connecting parts 131. The centers of the three first holes 141 form a triangle, and the centers of the three second connecting parts 131 also form a triangle. The two triangles are axially symmetric. The two triangles are nested between the second plate 140 and the transmission part 130, so that the driving force can be evenly transmitted through the three points, and the deflection reset distance is also evenly provided by the three points, reducing the problems of jamming and uneven wear.

[0041] In some embodiments, the protrusion 1221 is a hemispherical structure fixed to the first connecting portion 122, and the recess is configured as a hemispherical structure. Specifically, in conjunction with Figure 2 and Figure 4 As shown, the first connecting part 122 is a hemispherical screw, the protrusion 1221 is a spherical structure protruding towards the first plate 110, and the recessed part is a spherical structure recessed towards the first plate 110. The threaded end of the first connecting part 122 is screwed into the first plate 110, and the fixed connection is reliable. The protrusion 1221 of the first connecting part is a spherical structure protruding towards the first plate 110, which, together with the recessed part of the inner spherical structure, forms a low-friction, jam-free universal ball joint fulcrum. The first plate 110 can smoothly and adaptively deflect in multiple directions around the center of the ball. At the same time, the recessed part of the inner spherical structure guides the protrusion 1221 of the protruding spherical structure, improving the reset accuracy.

[0042] In some embodiments, the elastic element 121 is a spring, and the distance between the transmission part 130 and the first connecting part 122 is less than the distance when the spring is in a relaxed state. In the static state, the elastic element 121 is in a pre-compressed state, and the spring always exerts an outward pushing and continuous pre-pressure on the first connecting part 122 to ensure that the protrusion 1221 always fits with the recess, ensuring stability, reducing friction, and eliminating return gap, thereby improving response speed and accuracy.

[0043] Combination Figure 4 As shown, in some embodiments, the first connecting portion 122 is provided with a first groove 1222, and the transmission portion 130 includes a third plate with a second groove 134. The two ends of the spring are respectively disposed between the first groove 1222 and the second groove 134. The first groove 1222 and the second groove 134 can effectively prevent the spring from slipping off the mounting surface during compression, deflection, or vibration, ensuring the reliability of operation, facilitating installation and alignment, and improving assembly efficiency.

[0044] Combination Figure 4 As shown, in some embodiments, the first connecting portion 122 is provided with a second hole 1223 or the transmission portion 130 is provided with a third hole 132. One end of the spring extends outward with an insertion portion 1211, which is located on the axis of the spring and is accommodated in the second hole 1223 or the third hole 132. Specifically, one end of the second hole 1223 is located at the center of the first groove 1222, and the insertion portion 1211 is accommodated in the second hole 1223. Alternatively, one end of the third hole 132 is located at the center of the second groove 134, and the insertion portion 1211 is accommodated in the second hole 1223 or the third hole 132. This further prevents the spring from slipping during compression, deflection, or vibration, improves radial positioning accuracy, and ensures operational reliability.

[0045] Alternatively, the first connecting part is provided with a second hole 1223, the transmission part is provided with a third hole 132, and the two ends of the spring extend outward with insertion parts 1211. The insertion parts 1211 are located on the axis of the spring, and the insertion parts 1211 at both ends are respectively used to insert into the second hole 1223 and the third hole 132. The insertion parts 1211 at both ends of the spring are housed in the second hole 1223 or the third hole 132, which further prevents the spring from slipping during compression, deflection or vibration, improves radial positioning accuracy, and ensures that the spring, the first connecting part 122, and the third hole 132 are highly coaxial, thus ensuring the reliability of operation.

[0046] If the second hole 1223 is provided only in the first connecting part and the third hole 132 is provided in the transmission part, and the insertion parts 1211 at both ends of the spring are accommodated in the second hole 1223 or the third hole 132, the spring can also be prevented from slipping during compression, deflection or vibration.

[0047] In some embodiments, a limiting member 123 is provided between the first connecting portion 122 and the first plate 110. The limiting member 123 is used to restrict its position between the first plate 110 and the second plate 140. When the first connecting portion 122 passes through the first hole 141, and the first plate 110 is compressed and retracts towards the transmission portion 130, the limiting member 123 is used to prevent the first plate 110 from colliding with the second plate 140 and being damaged, and also to prevent the elastic member 121 from being crushed due to overload, thereby improving the life and safety of the labeling mechanism 100.

[0048] Specifically, the limiting member 123 is disposed on the first connecting portion 122, and the position of the limiting member 123 is set to the limit position of the retraction of the first plate 110. It can be understood that the limiting member 123 may also be fixed on the non-labeled side of the first plate 110 or on the side of the second plate 140 facing the first plate 110.

[0049] Specifically, the limiting member 123 is a nut provided on the first connecting part 122. The position of the nut on the first connecting part 122 is easy to adjust and has a locking function, and the position is stable.

[0050] Furthermore, gaskets 1231 can be provided between the limiting member 123 and the first plate 110, between the limiting member 123 and the second plate 140, and between the protrusion 1221 and the transmission part 130. The gaskets 1231 serve a protective function to prevent the parts from being damaged by collision.

[0051] Combination Figure 1 , Figure 3 , Figure 4 As shown, this application also provides a labeling device, including a labeling holder 200 and a labeling mechanism 100 as described above. The labeling holder 200 is used to place products to be labeled. The labeling device of this application can adapt to various complex labeling scenarios without adjusting the entire drive unit or product posture, thus enhancing the versatility and production efficiency of the equipment.

[0052] In some embodiments, the labeling mechanism 100 and / or the labeling holder 200 are provided with a rotating assembly for driving the labeling mechanism 100 and / or the labeling holder 200 to rotate along a straight line perpendicular to the first plate, so that the labeling mechanism 100 and the labeling holder 200 rotate relative to each other. The labeling mechanism 100 presses onto the product to be labeled, and the labeling holder 200 rotates relative to the labeling mechanism 100, which can squeeze and push out the air between the label and the product, improving the labeling yield.

[0053] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
