Description

Technical Field

[0001] This invention relates to the field of visual labeling technology, specifically to a visual labeling machine. Background Technology

[0002] Automatic vision labeling machines are high-end industrial equipment that combine mechanical automation, computer vision, and intelligent control technologies. They are widely used in product packaging and can achieve high-speed, high-precision label positioning, detection, and application.

[0003] Chinese patent CN202510307311.0 discloses labeling and assembly equipment for chip cartridges, including a conveyor line, a cap supply device, a label supply device, a cap support and positioning device, and a turnover device. The conveyor line is equipped with an assembly station, which includes a blocking mechanism and a barcode scanner. The cap supply device includes a cap discharge end. The label supply device includes a label generation unit and a label supply table. The cap support and positioning device includes a cap support and positioning table and a correction and positioning mechanism. The turnover device includes a picking mechanism with a negative pressure picking unit, which has turnover displacement capabilities.

[0004] The labeling and assembly equipment for chip boxes disclosed in this patent has problems such as transfer labels falling off, poor adhesion, and inability to adhere labels to the surface of inclined parts. Summary of the Invention

[0005] To address the above problems, this invention provides a vision labeling machine that, through a leveling clamping assembly, neatly arranges PCB boards while flexibly clamping and locking the sides of the PCB boards. This solves the technical problems of unstable clamping during PCB board inspection, easy skewing and warping affecting visual inspection, loose and uneven arrangement of multiple PCB boards, and easy wear and tear on the edges of the PCB boards during transport.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A visual labeling machine includes a frame, a conveying device mounted on the frame, a visual camera A disposed within the frame and with its line of sight directly facing the conveying device, and a display screen disposed outside the frame for real-time display. It also includes: A label supply organization, which outputs labels one by one to predetermined locations; and A label pasting mechanism that obtains labels from the label supply mechanism and then pastes them onto the products positioned and determined by the vision camera A on the conveying device. The label pasting mechanism includes an adsorption component and a smoothing component. The smoothing component works with the adsorption component to adsorb and acquire the label. The adsorption component and the smoothing component are separated in height, and the label is pasted at an acute angle relative to the product and smoothed by the smoothing component so that it adheres to the upper surface of the product.

[0007] As an improvement, the label supply mechanism includes an unwinding reel, a winding reel, and a peeling assembly. A roll of base tape is mounted on the unwinding reel, and the winding reel pulls the base tape through the peeling assembly, so that the label is peeled off the base tape for use.

[0008] As an improvement, the peeling assembly includes a base, a peeling plate, and a temporary storage plate. The base and the peeling plate are hollow and connected to a negative pressure. When the baseband passes through the peeling assembly, the base and the peeling plate separate the label from the baseband. The temporary storage plate is used to temporarily store the label.

[0009] As an improvement, the label pasting mechanism further includes a triaxial electric drive assembly, which drives the adsorption assembly and the smoothing assembly to move within the frame space.

[0010] As an improvement, the adsorption assembly includes a telescopic component and a suction nozzle, the suction nozzle being connected to a negative pressure, and the telescopic component driving the suction nozzle to extend for adsorbing the label.

[0011] As an improvement, the smoothing component includes a timing belt, a connector, a rotating shaft, a swing arm, and a roller. The connector connects the adsorption component and the timing belt respectively. The rotating shaft engages with the timing belt and moves accordingly. The lifting and lowering of the adsorption component drives the rotating shaft to rotate. The swing arm is rigidly connected to the rotating shaft, and the roller is installed at the end of the swing arm. When the adsorption component rises, it drives the roller to swing down through the rotating shaft to smooth and press the label.

[0012] As an improvement, the smoothing component also includes an auxiliary suction head, which is rigidly connected to the swing arm. When the adsorption component descends, the swing arm drives the roller to swing upward and retract, while the auxiliary suction head is moved to the same height position as the adsorption component. The auxiliary suction head and the adsorption component simultaneously adsorb the label.

[0013] As an improvement, a stop mechanism is also included, which is driven by the connector. When the adsorption assembly descends to affix the label to the product, the stop mechanism stops the side of the product to counteract the tendency of the roller to move the product to the side during smoothing.

[0014] As an improvement, the stop mechanism includes a slide rail, a stop member, a locking member, and an unlocking member. The slide rail is arranged parallel to the movement direction of the adsorption assembly. The stop member is installed on the slide rail. The connecting member is provided with a guide rod. The stop member slides on the guide rod, and an elastic member is fitted on the guide rod to reset the stop member. The locking member can lock the stop member when it has descended to the correct position. The unlocking member is installed on the synchronous belt and moves in the opposite direction to the connecting member. When the adsorption assembly rises to the top, the unlocking member unlocks the locking member to allow the stop member to rise again.

[0015] As an improvement, a vision camera B is also included, which is disposed on the stop member. When the adsorption assembly obtains the label at the label supply mechanism and affixes the label to the product, the vision camera B records video of the label.

[0016] The beneficial effects of this invention are as follows: (1) By setting the adsorption component and the auxiliary suction head together, the present invention can accurately and firmly adsorb the label at the label supply mechanism, and avoid the transfer label falling off; (2) By setting a height difference between the adsorption component and the auxiliary suction head, the present invention enables the label to be applied at an angle relative to the product surface, so that the label can be better aligned and firmly adhered; (3) The present invention uses a smoothing component to smooth the label on the product after the adsorption component completes the labeling action, thereby removing the air between the label and the product and strengthening the adhesion. (4) By setting a stop mechanism, the present invention prevents the product from moving and causing labeling failure when the adsorption component applies the label to the inclined product.

[0017] In summary, the present invention has the advantages of stable adsorption, firm adhesion, and adaptability to slanted labeling, and is especially suitable for the field of visual labeling technology. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and 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. Therefore, they should not be construed as limitations on this invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example 1: like Figures 1 to 3 , Figures 9 to 11 As shown, a visual labeling machine includes a frame 1, a conveying device 2 mounted on the frame 1, a visual camera A3 disposed inside the frame 1 with its line of sight directly facing the conveying device 2, and a display screen 4 disposed outside the frame 1 for real-time display. It also includes: Tag supply unit 5, which outputs tags 61 one by one to predetermined positions; and The label pasting mechanism 7 obtains a label 61 from the label supply mechanism 5 and then pastes it onto the product 8 on the conveying device 2, which is positioned and determined by the vision camera A3. The label pasting mechanism 7 includes an adsorption component 71 and a smoothing component 72. The smoothing component 72 works together with the adsorption component 71 to adsorb and acquire the label 61. The adsorption component 71 and the smoothing component 72 are separated in height, so that the label 61 is pasted at an acute angle relative to the product 8 and smoothed by the smoothing component 72 so that it adheres to the upper surface of the product 8.

[0023] It should be noted that the smoothing component 72, together with the adsorption component 71, adsorbs the label 61 to improve the adsorption firmness of the label and prevent it from falling off during the transfer process. The label 61 is pasted at an acute angle relative to the product 8 so that the label can be aligned when pasted and it is easy to expel the air between the label and the product, making the pasting reliable.

[0024] like Figure 4 , Figure 5 As shown, in a preferred embodiment, the label supply mechanism 5 includes an unwinding roller 51, a winding roller 52, and a peeling assembly 53. A rolled base tape 62 is mounted on the unwinding roller 51. The winding roller 52 pulls the base tape 62 through the peeling assembly 53, and the label 61 is peeled off from the base tape 62 for use.

[0025] In a preferred embodiment, the peeling assembly 53 includes a base 531, a peeling plate 532, and a temporary storage plate 533. The base 531 and the peeling plate 532 are hollow and connected to a negative pressure. When the baseband 62 passes through the peeling assembly 53, the base 531 and the peeling plate 532 separate the label 61 from the baseband 62. The temporary storage plate 533 is used to temporarily store the label 61.

[0026] It should be noted that the temporary storage plate 533 is made of a low-adhesion material, and the label 61 will not stick to the temporary storage plate 533.

[0027] In a preferred embodiment, the label pasting mechanism 7 further includes a triaxial electric drive assembly 73, which drives the adsorption assembly 71 and the smoothing assembly 72 to move within the internal space of the frame 1.

[0028] It should be noted that after the vision camera A3 illuminates the product 8, it accurately locates the position of the product 8 and transmits the acquired coordinate information to the three-axis electric drive component 73. The three-axis electric drive component 73 can then drive the adsorption component 71 and the smoothing component 72 to move above the product 8 to affix the label 61. The system control involved in this movement is a conventional technical means and will not be described in detail here.

[0029] like Figures 4 to 7 As shown, in a preferred embodiment, the adsorption component 71 includes a telescopic member 711 and a suction nozzle 712. The suction nozzle 712 is connected to a negative pressure, and the telescopic member 711 drives the suction nozzle 712 to extend for adsorbing the label 61.

[0030] It should be noted that the telescopic component 711 can be a controlled moving part, such as a cylinder or an electromagnet, and its extension stroke and speed are adjustable. The specific adjustment is based on enabling the nozzle 712 to accurately and reliably adsorb the label 61.

[0031] In a preferred embodiment, the smoothing component 72 includes a timing belt 721, a connector 722, a rotating shaft 723, a swing arm 724, and a roller 725. The connector 722 connects the adsorption component 71 and the timing belt 721 respectively. The rotating shaft 723 engages with the timing belt 721 and moves accordingly. The lifting and lowering of the adsorption component 71 drives the rotating shaft 723 to rotate. The swing arm 724 is rigidly connected to the rotating shaft 723, and the roller 725 is installed at the end of the swing arm 724. When the adsorption component 71 rises, the rotating shaft 723 drives the roller 725 to swing down and smooth and press the label 61.

[0032] It should be noted that the lifting and lowering of the adsorption component 71 is driven by the swing arm 724 via the synchronous belt 721. During the lifting process of the adsorption component 71, the swing arm 724 rotates around the center of the rotating shaft 723, which smooths the label 61 from one side to the other.

[0033] In a preferred embodiment, the smoothing component 72 further includes an auxiliary suction head 726, which is rigidly connected to the swing arm 724. When the adsorption component 71 descends, the swing arm 724 drives the roller 725 to swing upward and retract. At the same time, the auxiliary suction head 726 is moved to the same height position as the adsorption component 71, and the auxiliary suction head 726 and the adsorption component 71 simultaneously adsorb the label 61.

[0034] Example 2: like Figure 7 , Figure 8 As shown, in this embodiment, a stop mechanism 9 is also included. The stop mechanism 9 is driven by the connector 722. When the adsorption component 71 descends to affix the label 61 to the product 8, the stop mechanism 9 stops the side of the product 8 to counteract the tendency of the roller 725 to move the product 8 to the side when it is smoothing.

[0035] In a preferred embodiment, the stop mechanism 9 includes a slide rail 91, a stop member 92, a locking member 93, and an unlocking member 94. The slide rail 91 is arranged parallel to the movement direction of the adsorption assembly 71. The stop member 92 is mounted on the slide rail 91. The connecting member 722 is provided with a guide rod 7221. The stop member 92 slides on the guide rod 7221, and an elastic element is fitted on the guide rod 7221 to allow the stop member 92 to reset. The locking member 93 can lock the stop member 92 when it has descended to the correct position. The unlocking member 94 is mounted on the synchronous belt 721 and moves in the opposite direction to the connecting member 722. When the adsorption assembly 71 rises to the top, the unlocking member 94 unlocks the locking member 93 to allow the stop member 92 to rise back.

[0036] It should be noted that the stop 92 can block the product 8 until the adsorption component 71 rises to the top. At this time, the smoothing component 72 can keep the product 8 in a state of being restricted by the single-sided stop, thus preventing it from sliding. This is especially suitable for label 61 pasting work where the upper surface of the product 8 is not horizontal.

[0037] In a preferred embodiment, a vision camera B10 is also included. The vision camera B10 is disposed on the stop member 92. When the adsorption component 71 obtains the label 61 at the label supply mechanism 5 and affixes the label 61 to the product 8, the vision camera B10 records the label 61 video.

[0038] It should be noted that the visual camera B10 can also be replaced with a barcode scanner. As long as the verification of label 61 is completed, it can prevent label 61 from falling off or being missed.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
