Description

Technical Field

[0001] This utility model relates to the field of labeling machine structure, specifically a visual labeling machine. Background Technology

[0002] Traditional labeling machines often rely on manual adjustments during the labeling process, resulting in low efficiency and accuracy.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] refer to Figure 1-8A vision labeling machine includes a frame 1, a conveyor line 2, a label feeding device 3, a label gripping device 4, a first vision component 5, and a second vision component 6. The frame 1 serves as the supporting structure for the entire machine, ensuring the stable operation of all components. The conveyor line 2 is horizontally located on one side of the top of the frame 1 and is used to transport items to be labeled. The label feeding device 3 is located on the other side of the top of the frame 1, enabling automatic, continuous, and flat label supply. The label gripping device 4 is located between the label feeding device 3 and the conveyor line 2, and can grip the labels from the label feeding device 3 onto the items on the conveyor line 2, achieving automatic labeling. The first vision component 5 is located above the conveyor line 2 and captures images of the items on the conveyor line 2, thereby achieving precise positioning of the items on the conveyor line 2 and accurate labeling. The second vision component 6 is located below the label gripping device 4 and can accurately identify the labels before labeling, further improving the accuracy of automatic labeling.

[0055] In some embodiments, the label gripping device 4 includes a longitudinal moving component 41, a transverse moving component 42, a lifting component 43, and a gripping component 44. The longitudinal moving component 41 is located on the top of the frame 1, the transverse moving component 42 is located on the longitudinal moving component 41, the lifting component 43 is fixedly connected to the transverse moving component 42, and the gripping component 44 is fixedly connected to the lifting component 43. Through the cooperation of the longitudinal moving component 41, the transverse moving component 42, and the lifting component 43, the gripping component 44 can move in the longitudinal, transverse, and vertical directions, thereby moving the gripping component 44 to any position. Through the gripping and releasing of the gripping component 44, precise label gripping and automatic labeling of items are achieved. The longitudinal moving component 41, the transverse moving component 42, and the lifting component 43 may include structures such as motors, slide rails, sliders, and lead screws to realize the movement of the label gripping device 4 in the longitudinal, transverse, and vertical directions. This is prior art and will not be described in detail here.

[0056] In some embodiments, the gripping assembly 44 includes a gripping frame 441, a vacuum generator 442, and a labeling head 443. The gripping frame 441 is fixedly connected to the lifting assembly 43. The vacuum generator 442 is located at the top inside the gripping frame 441, and the labeling head 443 is located at the bottom inside the gripping frame 441 and connected to the vacuum generator 442. The vacuum generator 442 generates negative pressure in the labeling head 443, thereby achieving label gripping. This is prior art and will not be described in detail here.

[0057] In some embodiments, a fixing cover 7 is also included. The fixing cover 7 is disposed on the top of the frame 1 and a first vision component 5 is provided inside the fixing cover 7, which can fix and protect the first vision component 5.

[0058] In some embodiments, the first vision component 5 includes a light-emitting plate 51, a first camera 52, and a first lens 53. The light-emitting plate 51 is disposed inside the fixed cover 7 and above the conveyor line 2. The first camera 52 is disposed above the light-emitting plate 51. The first lens 53 passes through the light-emitting plate 51 and is connected to the first camera 52. The light-emitting plate 51 provides an illumination source to ensure that the first camera 52 and the first lens 53 capture images of the object under sufficient illumination, thereby obtaining the positioning coordinates of the object and achieving accurate positioning of the object.

[0059] In some embodiments, the second vision component 6 includes a light-emitting element 61, a second camera 62, and a second lens 63. The light-emitting element 61 is located below the label gripping device 4 and can be a light-emitting cover composed of multiple light-emitting panels. The second camera 62 is located below the light-emitting element 61, and the second lens 63 is located between the second camera 62 and the light-emitting element 61 and connected to the second camera 62. The light-emitting element 61 provides an illumination source to ensure that the second camera 62 and the second lens 63 capture label images under sufficient illumination, thereby accurately identifying the label before labeling. By obtaining the positioning coordinates of the label after peeling off the adhesive, the direction of the label is identified and matched with the positioning coordinates of the item obtained by the first vision component 5 to achieve accurate labeling of the item.

[0060] In some embodiments, the label feeding device 3 includes a fixed box 31, a drive unit, a take-up roller 32, an unwind roller 33, a V-shaped plate 34, driven rollers 35, and a peeling plate 36. The fixed box 31 is located on the other side of the top of the frame 1. The drive unit is located inside the fixed box 31 and can be a motor to provide rotational power to the take-up roller 32. The take-up roller 32 is rotatably located at the top of the fixed box 31 away from the conveyor line 2. The take-up roller 32 is connected to the drive unit. A label roll is detachably connected to the unwind roller 33 (this is prior art and will not be described in detail here). The unwind roller 33 is located above the take-up roller 32. The V-shaped plate 34 is located at the end of the fixed box 31 near the conveyor line 2. Multiple driven rollers 35 are rotatable. The label roll is mounted on the fixed box 31 and positioned between the take-up roller 32 and the V-shaped plate 34. The take-up roller 32, the unwind roller 33, the V-shaped plate 34, and multiple driven rollers 35 are connected to the label roll. The peeling plate 36 is located at the end of the V-shaped plate 34 away from the driven rollers 35. The take-up roller 32 is driven to rotate by the drive component, so that the label roll rotates between the take-up roller 32, the unwind roller 33, the V-shaped plate 34, and the multiple driven rollers 35. When the label on the label roll rotates to the peeling plate 36, the end face of the peeling plate 36 will peel the label off the label roll and let it fall onto the peeling plate 36, waiting for the label gripping device 4 to grab it, thereby achieving a continuous and stable supply of labels.

[0061] In some embodiments, the label feeding device 3 further includes an adjusting frame 37, an adjusting screw 38, an adjusting block 39, and a sensor. The adjusting frame 37 can be formed by connecting two fixed blocks and two connecting rods. The adjusting frame 37 is located at the bottom of the peeling plate 36. The adjusting screw 38 is rotatably connected to the adjusting frame 37. The adjusting block 39 can slide on the adjusting frame 37. The adjusting block 39 is provided through the adjusting screw 38 and is screwed into the adjusting screw 38. The sensor is located on the adjusting block 39 and is electrically connected to the label gripping device 4. The peeling plate 36 has a sensing groove corresponding to the sensor position to facilitate the sensor to sense the label on the peeling plate 36. The sensor can be a fiber optic displacement sensor, which can improve the sensing speed of the sensor. By rotating the adjusting screw 38, the adjusting block 39 moves on the adjusting frame 37, thereby adjusting the position of the sensor at the bottom of the peeling plate 36, so that the label feeding device 3 can be used for labels of different sizes. When the sensor senses a label on the peeling plate 36, the sensor sends a signal to the label gripping device 4, and the label gripping device 4 grips the label on the peeling plate 36.

[0062] In some embodiments, the conveyor line 2 includes a conveyor frame 21, a conveyor motor 22, a drive wheel 23, a driven wheel 24, a conveyor belt 25, a first clamp 26, and a second clamp 27. The conveyor frame 21 is horizontally disposed on one side of the top of the frame 1. The conveyor motor 22 is disposed on one side of the conveyor frame 21. The drive wheel 23 is disposed on one side of the conveyor frame 21 and is drivenly connected to the conveyor motor 22. The driven wheel 24 is disposed on the other side of the conveyor frame 21. The conveyor belt 25 is drivenly connected to the drive wheel 23 and the driven wheel 24. The first clamp 26 is disposed at one end of the conveyor belt 25, and the second clamp 27 is disposed at the other end of the conveyor belt 25, forming a guide channel with the first clamp 26. This guide channel can constrain the items on the conveyor line 2, ensuring the stability of the items during the conveying process, thereby further improving the accuracy of labeling. The guide channel can be Y-shaped to facilitate the introduction of items. The drive wheel 23 is driven by the conveyor motor 22 to rotate, thereby rotating the conveyor belt 25 and realizing the conveying of items on the conveyor line 2.

[0063] In some embodiments, a vision labeling machine further includes a control system, which may be mounted on the frame and the fixed cover 7, and may include a control circuit board, a display and other structures. The control system is electrically connected to the conveyor line 2, the label feeding device 3, the label gripping device 4, the first vision component 5 and the second vision component 6 to realize automated control of labeling of items and improve labeling efficiency.

[0064] The specific working principle is as follows:

[0065] The items to be labeled are conveyed to the designated position via conveyor line 2. The light-emitting plate 51 of the first vision component 5 provides sufficient illumination. The first camera 52 captures images of the items through the first lens 53 and transmits them to the control system for processing to determine the position and orientation of the items. The drive unit of the label feeding device 3 drives the take-up roller 32 to rotate, separating the labels from the label roll through the peeling plate 36 and finally placing them on the peeling plate 36. The label gripping device 4 moves the gripping component 44 above the label through the coordinated operation of the longitudinal moving component 41, the lateral moving component 42, and the lifting component 43. The vacuum generator 442 of the gripping component 44 is activated, adsorbing the label through the application head 443 and moving it above the second vision component 6. The light-emitting element 61 of the second vision component 6 provides illumination. The second camera 62 captures images of the labels through the second lens 63 and transmits them to the control system for processing to determine the position and orientation of the labels. Based on the positioning information from the first vision component 5 and the second vision component 6, the label gripping device 4 moves the label above the item on the conveyor line 2 through the coordinated operation of the longitudinal movement component 41, the lateral movement component 42, and the lifting component 43. The vacuum generator 442 then shuts off, and the label is precisely placed on the item. After labeling, the item continues to be conveyed to the next process via the conveyor line 2, completing the automatic labeling process.
