Description

Technical Field

[0001] This utility model relates to the field of label application technology for laptop computer shells, specifically a label quick-application and pressing device. Background Technology

[0002] In the production of laptops, the laptop casing is an important part of the product. The process of attaching labels to its surface has extremely high requirements for precision and stability. These casings are mostly made of materials such as aluminum alloy and plastic. After the surface is treated with polishing, spraying and other processes, the labels must not only adhere tightly to the surface without bubbles or wrinkles, but also ensure that the edges of the labels are strictly aligned with the reserved labeling area of ​​the casing. Otherwise, it will directly damage the overall aesthetics of the product and even affect subsequent assembly processes.

[0003] However, most existing labeling devices for laptop casings only use the lifting and lowering of the label to complete the labeling operation. However, this method has many drawbacks. During the label adsorption stage, these devices lack an effective detection and screening mechanism, and cannot promptly eliminate labels with unqualified positions or postures, causing errors to arise at the source and directly affecting the subsequent labeling quality.

[0004] Meanwhile, once the label is moved above the object to be labeled, the device cannot easily make precise horizontal adjustments based on the real-time positioning data of the object. This results in poor initial alignment accuracy between the label and the object to be labeled, making it prone to positional deviations during subsequent application. Once a label is misaligned, the defective label often has to be discarded, and it may even damage the workpiece to be labeled. This not only wastes a large number of labels but also significantly increases the scrap rate, greatly increasing raw material costs and overall production costs.

[0005] Therefore, we propose a label fast-application and pressing device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a label fast-application and pressing device to solve the problems mentioned in the background art, such as the inability to promptly eliminate labels with unqualified positions or postures, which leads to errors originating from the source and directly affecting the subsequent application quality, and the difficulty in adjustment causing positional deviations during the application process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a label fast application and pressing device, comprising a label applicator body, a label receiving and dispensing mechanism mounted on the label applicator body, a first lead screw slide table mounted on the label applicator body, a second lead screw slide table slidably mounted on the first lead screw slide table, a slide block slidably connected to the second lead screw slide table, a mounting base fixed to the side wall of the slide block, limit blocks symmetrically fixed to the end side of the mounting base, a slide frame slidably connected inside the limit blocks, a rotating rod rotatably connected to the slide frame, a vacuum suction head fixed to the bottom of the rotating rod, a label body adsorbed at the bottom of the vacuum suction head, and a CCD detector fixed to the side wall of the slide frame;

[0008] The labeling machine body is equipped with a conveyor table, on which a laptop casing is conveyed. A limit component is installed inside the conveyor table, and a lifting component and a rotating component are installed on the mounting base.

[0009] Preferably, the limiting component includes a vacuum pump fixedly connected to the side wall of the labeling machine body, a suction tube connected to the vacuum pump, a suction cup connected to the end of the suction tube, a support block fixed to the end of the suction cup, and the support block fixedly connected to the conveyor table.

[0010] Preferably, the lifting assembly includes a cylinder fixedly connected to the mounting base. The cylinder has a cavity, and a spring is provided in the cavity. One end of the spring is fixedly connected to the cylinder, and the other end of the spring is fixedly connected to a piston. A slide rod is fixedly connected to the bottom of the piston, and the slide rod is fixedly connected to a slide frame.

[0011] Preferably, the rotating assembly includes a through hole formed in the side wall of the cylinder, the side wall of the through hole is connected to a flexible hose, a locking block is fixed on the surface of the carriage, a receiving column is locked in the locking block, the side wall of the receiving column is provided with a leakage hole, and the receiving column is connected to the flexible hose.

[0012] Preferably, the receiving column has a groove that communicates with the leakage hole. A second spring is installed in the groove. One end of the second spring is fixedly connected to the receiving column, and the other end of the second spring is fixed with a push rod. The push rod slides against the inner wall of the receiving column. A connecting frame is fixed to the end of the push rod, and a connecting rod is fixed to the end of the connecting frame.

[0013] Preferably, the slide is symmetrically fixed with support blocks, and a toothed plate is slidably connected inside the support block. The toothed plate is fixedly connected to the connecting rod, and a gear is fixed to the outer ring of the rotating rod. The gear meshes with the toothed plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Through the coordinated operation of lead screw slide one and lead screw slide two, precise positioning is achieved during the label adsorption and transfer process. Combined with the real-time detection of label position and posture by the CCD detector, unqualified labels can be eliminated during the adsorption stage, reducing errors at the source. Subsequent horizontal fine-tuning based on the data of the object to be labeled further ensures the accuracy of the initial label alignment. The pressure is precisely transmitted to the vacuum adsorption head through the slide, ensuring that the label body is firmly attached to the surface of the object to be labeled, reducing the risk of label detachment. The rotating component adjusts the label application and pressing process to correct label deflection in real time, avoiding label waste due to positional deviation, reducing the scrap rate, and thus achieving effective savings in raw materials and production costs.

[0016] 2. The stable negative pressure generated by the vacuum pump is transmitted to the suction cup through the suction tube. The suction cup cooperates with multiple cavities on the conveyor table to increase the contact and adsorption area with the laptop shell, making the adsorption more firm and uniform. This ensures that the shell will not shift or shake during the conveying and application process, providing a stable foundation for the labeling operation.

[0017] 3. From the release of labels by the label receiving and discharging mechanism, to the movement of components driven by the screw slide, the adsorption of labels by the vacuum suction head, the detection by the CCD detector, and the coordinated completion of labeling and angle adjustment by the lifting and rotating components, and then to the automatic reset after labeling, the entire process is highly automated. The continuous conveying of the conveyor and the coordinated operation of each component reduce manual intervention, enabling labeling operations to be carried out continuously and efficiently, and significantly improving overall work efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 4 A label fast application and pressing device includes a labeling machine body 1, on which a label receiving and dispensing mechanism 2 is installed. The label receiving and dispensing mechanism 2 is responsible for the supply and recycling of the label body 12 to ensure a continuous source of labels. This is prior art and will not be described in detail.

[0026] The labeling machine body 1 is equipped with a lead screw slide 3, and a second lead screw slide 4 is slidably mounted on the first lead screw slide 3. A slide block 5 is slidably connected to the second lead screw slide 4. The first lead screw slide 3 and the second lead screw slide 4 form a two-dimensional moving platform. The first lead screw slide 3 can slide in a certain horizontal direction, while the second lead screw slide 4 can slide in another horizontal direction based on the first lead screw slide 3. The two work together to drive the slide block 5 and subsequent connected components to make precise horizontal position adjustments to meet the needs of different labeling positions.

[0027] A mounting base 6 is fixed to the side wall of the slide 5. A limiting block 7 is symmetrically fixed to the end of the mounting base 6. A slide 8 is slidably connected inside the limiting block 7. A rotating rod 9 is rotatably connected to the slide 8. A vacuum adsorption head 10 is fixed to the bottom of the rotating rod 9. The vacuum adsorption head 10 adsorbs the label body 12 by negative pressure. Its adsorption force can be adjusted according to the material and weight of the label body 12 to ensure stable adsorption of the label without damaging it. The label body 12 is adsorbed at the bottom of the vacuum adsorption head 10. A CCD detector 11 is fixed to the side wall of the slide 8, which can detect the position and posture of the label body 12 and the position of the object to be labeled in real time, providing data support for subsequent accurate labeling.

[0028] A lifting assembly 16 is installed on the mounting base 6. The lifting assembly 16 includes a cylinder 161 fixedly connected to the mounting base 6. A cavity 162 is opened in the cylinder 161. A spring 163 is installed in the cavity 162. One end of the spring 163 is fixedly connected to the cylinder 161. A piston 164 is fixedly connected to the other end of the spring 163. A slide rod 165 is fixedly connected to the bottom of the piston 164. The slide rod 165 is fixedly connected to the slide frame 8.

[0029] A rotating assembly 17 is mounted on the mounting base 6. The rotating assembly 17 includes a through hole 171 formed in the side wall of the cylinder 161. A flexible hose 172 is connected to the side wall of the through hole 171. The through hole 171 provides a flow channel for the gas in the cylinder 161. The flexible hose 172 serves as a gas transmission device, guiding the gas in the cylinder 161 to the receiving column 173. A locking block 174 is fixed to the surface of the slide 8. The receiving column 173 is engaged in the locking block 174. A leakage hole 175 is formed in the side wall of the receiving column 173. The receiving column 173 is connected to the flexible hose 172. Both the cylinder 161 and the receiving column 173 are equipped with pressure relief valves to facilitate pressure relief operations. A groove 176 is provided, which is connected to a drain hole 175. A second spring 177 is installed in the groove 176. One end of the second spring 177 is fixedly connected to the receiving column 173, and the other end of the second spring 177 is fixedly connected to a push rod 178. The push rod 178 slides against the inner wall of the receiving column 173. A connecting frame 179 is fixedly fixed to the end of the push rod 178, and a connecting rod 791 is fixedly fixed to the end of the connecting frame 179. Support blocks 793 are symmetrically fixed on the slide 8. A toothed plate 792 is slidably connected in the support block 793. The toothed plate 792 is fixedly connected to the connecting rod 791. A gear 794 is fixedly fixed to the outer ring of the rotating rod 9. The gear 794 meshes with the toothed plate 792.

[0030] In this embodiment: After the label receiving and dispensing mechanism 2 releases the label body 12, the lead screw slide 3 and the lead screw slide 4 immediately work together to drive the slide 5 to move precisely to the label receiving and dispensing mechanism 2. At this time, the vacuum adsorption head 10 is aligned with the label body 12 and activated, and the label body 12 is firmly adsorbed by negative pressure. At the same time, the CCD detector 11 on the side wall of the slide 8 is activated synchronously to detect the label body 12 in the adsorption state and accurately confirm whether its position and posture meet the preset standards.

[0031] Subsequently, based on the label position information fed back by the CCD detector 11 and combined with the positioning data of the object to be labeled, the system drives the lead screw slide 3 and lead screw slide 4 to move together again, and the slide 5 and connected components move accordingly, smoothly transporting the label body 12 to directly above the object to be labeled, and through fine horizontal adjustments, the label body 12 is initially aligned with the position to be labeled, laying the foundation for subsequent labeling.

[0032] When the label body 12 reaches above the labeling position, the lifting assembly 16 starts working, injecting gas into the cylinder 161. A displacement sensor inside the cylinder 161 monitors the downward movement distance of the piston 164 in real time. As the gas volume continues to increase, an upward thrust is generated within the cylinder 161, pushing the piston 164 downward. The piston 164 drives the slide rod 165 and the slide 8 to descend synchronously. The slide 8 slides stably along the inner wall of the limiting block 7, and the vacuum suction head 10 and the label body 12 move downward accordingly. During this process, the spring 163 is gradually stretched. When the displacement sensor detects that the piston 164 has moved down to a preset distance, at which point the vacuum suction head 10 is just in contact with the surface of the object to be labeled, the system controls the cylinder 161 to stop injecting gas, and the piston 164 stops moving downward. At this time, the vacuum adsorption head 10 stops working and releases the label body 12 to complete the initial attachment. During the attachment process, the lifting component 16 can adjust the pressure according to actual needs and transmit the pressure to the vacuum adsorption head 10 through the slide 8 to precisely press the label body 12 to ensure that it is firmly attached.

[0033] If the CCD detector 11 detects a deflection of the label body 12 during the application process, the system immediately activates the angle adjustment mechanism. Since the piston 164 is already limited to the preset downward distance position, increasing the air pressure in the cylinder 161 will not push the piston 164 to continue downward. Instead, the gas will enter the receiving column 173 through the through hole 171 and the hose 172, and then flow into the groove 176 through the drain hole 175, pushing the push rod 178 to move and stretching the second spring 177. When the push rod 178 slides, the connecting bracket 179 on its end side moves synchronously with the connecting rod 791, causing the toothed plate 792 to slide along the inner wall of the support block 793. The toothed plate 792 and the gear 794 on the outer ring of the rotating rod 9 will mesh and drive the rotating rod 9 to drive the vacuum suction head 10 to rotate, adjusting the angle of the label body 12 in real time. This dynamic adjustment process can ensure that the label body 12 is accurately adapted to the surface of the object to be labeled during the pressing stage, effectively avoiding label waste and increased workpiece defect rate due to positional deviation.

[0034] After the labeling operation is completed, the pressure relief valves on cylinder 161 and receiving column 173 open synchronously, and the internal gas is quickly discharged. Under the restoring force of spring 163, slide rod 165 drives slide 8 to return to its original position, and vacuum suction head 10 disengages from the labeling position. At the same time, spring 2177 pulls push rod 178 back to its original position, and toothed plate 792, gear 794 and rotating rod 9 return to their initial state in sequence. The entire device waits for the next labeling cycle.

[0035] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1 and Figure 5A rapid labeling and pressing device includes a labeling machine body 1, on which a conveyor table 13 is installed. Using a continuous conveying method, it can stably transport a laptop casing 14 from the loading end of the device to the labeling station, and then transport the labeled casing to the unloading end. The conveying speed of the conveyor table 13 can be adjusted according to the rhythm of the overall labeling process, ensuring precise matching with each stage of labeling and pressing, achieving efficient continuous operation. Its surface is usually specially treated, such as using wear-resistant and smooth materials, to reduce friction with the laptop casing 14 and avoid scratches or other damage to the casing surface. A laptop casing 14 is conveyed on the conveyor table 13. A limiting component 15 is installed inside the conveyor table 13. The limiting component 15 includes a vacuum pump 151 fixedly connected to the side wall of the labeling machine body 1. The vacuum pump 151 provides a negative pressure power source. It can generate a stable negative pressure to provide sufficient suction for the suction cup 153 to adsorb the laptop casing 14. The suction force can be adjusted according to the material and weight of the casing to prevent the casing from being damaged by excessive suction or the casing from being unstable due to insufficient suction. A suction tube 152 is connected to the vacuum pump 151. A suction cup 153 is connected to the end of the suction tube 152. A support block 154 is fixed to the end of the suction cup 153. The support block 154 is fixedly connected to the conveyor table 13. Both the suction cup 153 and the conveyor table 13 are provided with multiple cavities for precise positioning and fixing of the laptop casing 14 during conveying, ensuring that the casing does not shift during labeling.

[0036] In this embodiment: When the device is started, the conveyor 13 starts to operate, transporting the laptop casing 14 to be labeled from the initial position to the labeling station. When the laptop casing 14 is about to reach the labeling station, the limiting component 15 starts to work, the vacuum pump 151 starts, and the air in the suction cup 153 is extracted through the suction tube 152, so that a negative pressure is formed inside the suction cup 153. When the laptop casing 14 is transported above the suction cup 153 and comes into contact with the suction cup 153, under the action of the negative pressure, the suction cup 153 firmly adheres to the laptop casing 14, achieving initial fixation.

[0037] Since the support block 154 stably fixes the suction cup 153 on the conveyor table 13, and the suction force of the suction cup 153 is stable and reliable, the laptop casing 14 will not shift or shake during the process of being conveyed to the labeling station by the conveyor table 13, ensuring that the casing can accurately reach the preset labeling position.

[0038] When the laptop casing 14 reaches the labeling station, the conveyor 13 stops conveying. At this time, the limiting component 15 continues to hold the laptop casing 14 in place, providing a stable working platform for subsequent label application and pressing. During the process of the label body 12 being transported to the labeling position by the vacuum suction head 10 and being applied and pressed, the laptop casing 14 is firmly fixed, avoiding label application position deviation caused by casing movement, thus ensuring labeling accuracy.

[0039] Once the label is applied and pressed, the vacuum pump 151 stops working, the negative pressure in the suction cup 153 disappears, releasing the adsorption on the laptop casing 14. Subsequently, the conveyor 13 restarts, transporting the labeled laptop casing 14 to the unloading end, while simultaneously transporting the next casing to be labeled to the labeling station. The limiting component 15 repeats the above process, achieving continuous and efficient label application.
