Description

Technical Field

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

[0002] Labeling machines are widely used in production processes such as product identification, quality traceability, and warehousing sorting. Their core function is to accurately affix labels to the surface of manufactured parts. In automated labeling operations for components such as new energy battery heat insulation panels, electronic components, and sheet materials, the parts need to be conveyed to the labeling station by a feeding mechanism, and then the labeling mechanism completes the labeling. In this process, the positioning accuracy of the parts at the labeling station directly determines the final labeling quality.

[0003] Existing labeling machines commonly employ two methods for part positioning: one is to transport the part to the labeling station via a conveyor belt, using a stop mechanism or positioning pin at the station to stop and position the part; the other is to use an adsorption conveyor belt to directly transport the part to the labeling station, relying on a reference surface at the station for single-stage positioning. However, these positioning methods have the following drawbacks: First, the part lacks continuous guiding constraints during transportation, making it prone to swaying or displacement. By the time it reaches the labeling station, a certain positional deviation has already occurred, and the positioning structure at the final station alone cannot completely eliminate this accumulated error. Second, for long sheet-like parts, even slight swaying during transportation can be amplified, resulting in rigid contact between the part and the positioning structure during final positioning. This not only affects positioning accuracy but may also damage the edges of the part. Third, single-stage positioning requires extremely high precision in the preceding transportation stages. Even a slight deviation during transportation can lead to a significant deviation in the final labeling position, making it difficult to meet the continuous operation requirements for high-precision labeling.

[0004] Therefore, how to increase the guiding constraints on the transportation process of manufactured parts in order to improve the labeling accuracy is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a labeling machine that achieves initial positioning of the suction fixture and the adsorbed parts through the sliding cooperation of the guide rail and the guide component, and then performs secondary positioning of the parts through the positioning component, forming a two-level positioning connection mechanism, which effectively eliminates the cumulative error generated by the parts during transportation and significantly improves the labeling accuracy.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention discloses a labeling machine, comprising a labeling mechanism, a feeding mechanism, and a transport positioning mechanism for transporting parts to the labeling mechanism, characterized in that the transport positioning mechanism comprises: A suction fixture is used to adsorb components; guide elements are provided at both ends of the positioning beam of the suction fixture. The guide rails are located at both ends of the suction fixture, and the guide rails are slidably connected to the guide members; A feeding tray, located inside the guide rail, is used to support the workpiece; The positioning component is slidably connected to the unloading tray.

[0007] As a further aspect of the present invention: the labeling mechanism includes: A transverse module is provided, extending along the first direction; An adjustment module extends along a second direction perpendicular to the first direction, and the adjustment module and the lateral movement module are slidably connected. The labeling head is installed on the transverse module and is driven by the transverse module to move along the first direction.

[0008] As a further aspect of the present invention: the labeling head includes a peeling member having a wedge-shaped tip for separating the label from the backing paper; the labeling head also includes a pressing member having a smooth pressing end for pressing the label onto the surface of the workpiece.

[0009] As a further aspect of the present invention, it also includes a label feeding mechanism, which includes a label feeding tray, a reel for collecting the empty backing paper after the label has been peeled off, and a power assembly disposed between the label feeding tray and the reel.

[0010] As a further aspect of the present invention, it also includes a cleaning mechanism, wherein the cleaning structure is mounted on the transverse module and is driven by the transverse module to move along a first direction.

[0011] As a further aspect of the present invention, it also includes a visual inspection mechanism for detecting labeling accuracy, the visual inspection mechanism being connected to the labeling head.

[0012] As a further aspect of the present invention: the feeding mechanism includes a feeding bin for stacking and storing parts to be labeled, the bottom of the feeding bin having a liftable feeding tray and a motor for driving the feeding tray to move up and down.

[0013] As a further aspect of the present invention, it also includes an electrical box, in which a PLC controller is installed, and the PLC controller is electrically connected to the labeling mechanism, the feeding mechanism, the transport positioning mechanism, the label supply mechanism, the cleaning mechanism, and the visual inspection mechanism.

[0014] As a further embodiment of the present invention: the positioning element is an L-shaped plate; and / or, The suction fixture also includes suction ports spaced apart on one end face of the positioning beam.

[0015] As a further aspect of the present invention: the guide member is a roller, and the guide rail has a groove along its length for accommodating the roller.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention uses the sliding cooperation between the guide rail and the guide component to provide precise guidance for the suction fixture and the adsorbed parts throughout the process, thereby achieving the initial positioning of the parts during transportation and effectively preventing the parts from swaying or shifting during long-distance transportation. (2) By setting a positioning component that is slidably connected to the unloading tray, the parts transported to the labeling station are positioned for a second time, and the parts are directly abutted against the end of the parts to accurately correct them to the preset labeling position; (3) The two-level positioning is interconnected. The initial positioning ensures the accurate arrival of the parts, and the secondary positioning ensures the accurate placement of the parts. This effectively eliminates the cumulative error generated during transportation, greatly improves the labeling accuracy, and avoids hard collision damage between the edge of the parts and the positioning structure. It takes into account both transportation stability and labeling accuracy, and is suitable for large-volume, high-precision automated labeling operations of long-size sheet metal parts.

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.

Therefore, they should not be construed as limitations on this invention.

[0020] Please see Figure 1-5 This embodiment discloses a labeling machine, including a labeling mechanism 1, a feeding mechanism 2, and a transport positioning mechanism 3 for transporting the workpiece 6 to the labeling mechanism 1. The transport positioning mechanism 3 includes a suction fixture 31, a guide rail 33, and a discharge tray 34, wherein: The suction fixture 31 is used to adsorb the workpiece 6. The positioning beam 311 of the suction fixture 31 has an array of adsorption ports 312 on its surface. Its adsorption surface is a planar structure adapted to the contour of the upper plane of the workpiece 6, and the area of ​​the adsorption area is not less than 80% of the effective area of ​​the upper plane of the board. The workpiece can be stably fixed by negative pressure adsorption. The positioning beam 311 is fixedly connected to the suction fixture 31, and the two ends of the positioning beam 311 are provided with guide members 313. The guide rail 33 is located at both ends of the positioning beam 311, and the guide rail 33 is slidably connected to the guide members 313. The unloading tray 34 is located inside the guide rail 33 and is parallel to the guide rail 33. The unloading tray is used to support the two ends of the workpiece 6. The positioning member 32 is slidably connected to the unloading tray 34. Through the sliding engagement of guide rail 33 and guide component 313, the suction fixture 31 and the adsorbed part 6 are precisely guided throughout the process, achieving the initial positioning of part 6 during transportation; at the same time, through the sliding connection between positioning component 32 and unloading tray 34, the part 6 transported to the labeling station is positioned a second time. The two-stage positioning is interconnected, effectively eliminating the cumulative error during transportation and improving the labeling accuracy.

[0021] Furthermore, the labeling mechanism 1 includes a horizontal movement module 11 and an adjustment module 12. The horizontal movement module 11 extends along a first direction (horizontal direction); the adjustment module 12 extends along a second direction (vertical direction) perpendicular to the first direction, and the adjustment module 12 and the horizontal movement module 11 are slidably connected. The labeling head 13 is mounted on the horizontal movement module 11. The labeling head 13 can move horizontally in the first direction to achieve full-width labeling or fixed-point labeling, and can also move vertically in the second direction to adapt to parts 6 of different thicknesses, improving the versatility and labeling flexibility of the equipment.

[0022] Furthermore, the labeling head 13 includes a peeler 131 with a wedge-shaped tip for separating the label from the backing paper; the labeling head 13 also includes a pressing member 132 with a smooth pressing end for pressing the label onto the surface of the component 6. The wedge-shaped tip of the peeler 131 can smoothly separate the label from the backing paper, avoiding tearing or wrinkling of the label; the smooth pressing end of the pressing member 132 can elastically adhere the label to the surface of the component 6, effectively removing air bubbles and ensuring that the label is flat and firm.

[0023] Furthermore, it also includes a label feeding mechanism 4, which includes a label feeding tray 41, a reel 42 for collecting the empty backing paper after the label has been peeled off, and a power assembly 43 located between the label feeding tray 41 and the reel 42. The label is wound on the label feeding tray 41, passes through the guide 44, and is unwound by the traction force provided by the power assembly 43. The empty backing paper of the label is finally wound on the rotating reel 42. Through the coordinated work of the label feeding tray 41, the reel 42, and the power assembly 43, automatic label feeding and automatic backing paper collection are achieved, ensuring the continuity of the labeling operation and reducing manual intervention. The guide 44 is used to tension and guide the direction of the label tape as it is conveyed from the label feeding tray 41 to the labeling head 13, ensuring that the label tape enters the peeling station smoothly and accurately.

[0024] It should be noted that the label-laying plate 41 is fixedly connected to the base plate used to fix the roll 42 as a whole, and the two are installed together on the transverse module 11; the label-applying head 13 is also installed on the base plate, so that it moves synchronously with the label-laying plate 41 and the transverse module 11.

[0025] Furthermore, it also includes a cleaning mechanism 5, which is specifically a plasma cleaning module installed on the transverse module 11. Driven by the transverse module 11, it moves along the first direction and can automatically clean the surface of the workpiece 6 before labeling, removing dust and oil stains and improving the reliability of label application.

[0026] Furthermore, it also includes a vision inspection mechanism 7 for detecting labeling accuracy, which is connected to the labeling head 13. The vision inspection mechanism 7 can capture the label position image in real time during the labeling process, synchronously detect the labeling accuracy, ensure accurate label placement, and promptly detect and alarm deviations.

[0027] Furthermore, the feeding mechanism 2 includes a feeding bin 21 for stacking and storing parts 6 to be labeled. The bottom of the feeding bin 21 has a liftable feeding tray 22 and a motor that drives the feeding tray 22 to move up and down. The lifting tray 22 and motor at the bottom of the feeding bin 21 ensure that the stacked parts 6 are always kept at the same picking height, which facilitates stable picking by the suction fixture 31 and realizes continuous automatic feeding.

[0028] Furthermore, it also includes an electrical box 8, which contains a PLC controller. The PLC controller is electrically connected to the labeling mechanism 1, the feeding mechanism 2, the transportation and positioning mechanism 3, the label supply mechanism 4, the cleaning mechanism 5, and the visual inspection mechanism 7, and coordinates the entire process of the various mechanisms to operate in a coordinated manner.

[0029] Furthermore, the positioning element 32 is an L-shaped plate, which can abut and limit the end of the part 6 from two directions to achieve a more stable and reliable secondary positioning.

[0030] Furthermore, the guide component 313 is a roller, and the guide rail 33 has a groove along its length to accommodate the roller. The guide component 313 adopts a roller structure, and the groove on the guide rail 33 cooperates with it, converting sliding friction into rolling friction, reducing motion resistance and wear, and improving guiding accuracy and service life.

[0031] At the start of operation, the operator places the stacked parts 6 into the loading bin 21 of the loading mechanism 2. The loading tray 22 at the bottom of the loading bin 21 is gradually raised under the drive of the motor, so that the top part 6 is always kept at the same picking height, which facilitates the stable picking up by the suction fixture 31.

[0032] The suction fixture 31 slides along the guide rail 33 above the loading bin 21, and adsorbs the upper surface of the part 6 through the array of adsorption ports 312 at its top. After adsorption and fixation, the suction fixture 31 continues to slide, transferring the part 6 from the loading bin 21 to the labeling area. During this process, the guides 313 at both ends of the positioning beam 311 slide and cooperate with the guide rail 33 to provide precise guidance for the suction fixture 31 and the adsorbed part 6 throughout the process, achieving the initial positioning of the part 6 and effectively preventing swaying or displacement during transportation.

[0033] After the suction fixture 31 transports the part 6 to the labeling area, the negative pressure is released, and the part 6 falls onto the unloading tray 34. The positioning component 32 clamps the two ends of the part 6, accurately aligning it to the preset labeling position, completing the secondary positioning. Through the two-stage connection of primary and secondary positioning, the accumulated error during transportation is effectively eliminated, ensuring that the part 6 is positioned at the labeling station with high precision.

[0034] It should be noted that when part 6 falls onto tray 34, there is a small gap between the top surface of part 6 and air inlet 312; this gap allows part 6 to detach smoothly from air inlet 312 after the suction fixture releases the negative pressure.

[0035] After the part 6 is positioned and fixed, the cleaning mechanism 5 is started. The cleaning mechanism 5 is installed on the transverse module 11 and is driven by the transverse module 11 to move synchronously with the labeling head 13 in the first direction to perform scanning cleaning on the upper surface of the part 6, removing dust and oil stains from the surface to improve the adhesion reliability between the label and the part 6.

[0036] After cleaning, the labeling head 13 begins operation. The labeling head 13 is mounted on the transverse module 11, and the adjusting module 12 is slidably connected to the transverse module 11. The transverse module 11 drives the labeling head 13 to move along a first direction above the workpiece 6. The adjusting module 12 adjusts the vertical height of the labeling head 13 along a second direction according to the thickness of the workpiece 6, ensuring that the peeling member 131 and the pressing member 132 maintain a suitable working distance from the surface of the workpiece 6. The label feeding mechanism 4 releases a roll of label tape from its label feeding tray 41, which is then conveyed to the labeling head 13 via the power assembly 43. The peeling member 131, with its wedge-shaped tip, smoothly peels the label from the backing paper, while the pressing member 132, with its smooth pressing end, elastically adheres the label to the surface of the workpiece 6 and applies downward pressure to remove air bubbles, ensuring the label is flat and secure. During the labeling process, the vision inspection mechanism 7, connected to the labeling head 13, captures the label position image in real time and simultaneously detects the labeling accuracy. If the deviation exceeds the allowable range, a signal is sent to the electrical control box 8 to control the equipment to stop and alarm.

[0037] After labeling is completed and the visual inspection mechanism 7 confirms that the accuracy meets the standard, the suction fixture 31 uses negative pressure to adsorb and fix the labeled part 6, and then continues to slide along the guide rail 33 to send the part 6 to the unloading bin (located at the other end of the loading tray 34, symmetrical to the loading bin 21). After ensuring that the part 6 falls smoothly into the predetermined position, the negative pressure is released to complete the unloading.

[0038] After the material is unloaded, the suction fixture 31 continues to slide along the guide rail 33 back to the loading mechanism 2, waiting for the next material picking action; at the same time, the labeling head 13 and the cleaning mechanism 5 move to the return-to-origin position under the drive of the transverse module 11 and are in standby mode, waiting for the next labeling instruction. This cycle repeats, thus realizing the continuous, automated, and precise labeling operation of the part 6.

[0039] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0040] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
