Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, and specifically relates to an automatic weighing and anti-tamper labeling device. Background Technology

[0002] With the rapid development of the smartphone manufacturing industry, the level of automation in product packaging is constantly improving. In the smartphone manufacturing process, the color box, as the outer packaging, is a key component in ensuring product quality through weighing and tamper-evident label application. Currently, this is typically done manually, requiring separate operators for weighing and labeling. The weighing operator first uses a manual weighing device to check the weight of the color box, and then the labeling operator manually applies the tamper-evident labels to specific locations on the box. This process is labor-intensive, and the speed of manual operation is limited by individual labor intensity. Prolonged repetitive work can easily lead to fatigue, resulting in unstable inspection rhythms, human error, and low production efficiency, affecting product yield and quality stability.

[0003] Therefore, it is necessary to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

Figure 10 This is a schematic diagram of the NG unloading component in an automatic weighing and anti-tamper labeling device provided in this embodiment of the utility model. Figure 11 This is a schematic diagram of the feeder label dispensing component in an automatic weighing and anti-tamper labeling device provided in this embodiment of the utility model. Figure 12 This is a schematic diagram of the labeling component in an automatic weighing and anti-tampering labeling device provided in this embodiment of the present invention. The automatic weighing and anti-tampering labeling device provided in this embodiment of the present invention includes a lifting weighing component 1, a positioning component 2, a feeder label dispensing component 3, and a labeling component 4. The lifting weighing component 1 and the positioning component 2 are arranged sequentially along the transport direction of the color box. The lifting weighing component 1 includes a first conveying mechanism 11 and a weighing mechanism 12. The first conveying mechanism 11 is used to transport the color box to the positioning component 2, and the weighing mechanism 12 is used to weigh the color box. The positioning component 2 includes a second conveying mechanism 21 and a positioning mechanism 22. The second conveying mechanism 21 is used to receive the color box from the first conveying mechanism 11, and the positioning mechanism 22 is used to position the color box. The feeder label dispensing component 3 is used to peel off the label, and the labeling component 4 is used to attach the peeled label to the color box located at the positioning mechanism 22.

[0036] In this process, the color box can be initially placed or flow into the first conveyor mechanism 11 of the lifting and weighing assembly 1. The first conveyor mechanism 11 can also be a belt conveyor or a roller conveyor. The color box is initially transported within the equipment by the first conveyor mechanism 11. Simultaneously, when the color box reaches the weighing mechanism 12, the weight of the color box is measured in real time or with a short pause to obtain the weight information of the color box. The weighing mechanism 12 can also include a precision electronic scale located below the first conveyor mechanism 11. For example, the first conveyor mechanism 11 can be lowered as a whole by a lifting cylinder, so that the color box is separated from the first conveyor mechanism 11. At the same time, the color box comes into contact with the precision electronic scale to realize the weight measurement of the color box. Then, the first conveyor mechanism 11 can be raised as a whole by a lifting cylinder, so that the color box comes into contact with the first conveyor mechanism 11 to continue to be transported downstream by the first conveyor mechanism 11.

[0037] The weighed color boxes are conveyed by the first conveyor mechanism 11 to the second conveyor mechanism 21 of the positioning component 2. The second conveyor mechanism 21 can be a roller conveyor or belt conveyor with positioning function. The second conveyor mechanism 21 can receive the color boxes and convey them to the preset labeling station. When the color box arrives at the labeling station, the positioning mechanism 22 starts working. The positioning mechanism 22 can be like a horizontally movable push plate to push the color box into the required position, such as fine-tuning or forcefully correcting the color box from the side or end, so as to avoid slight deviation or rotation caused by the conveying, and promptly adjust and fix the color box to the target position and angle, so as to establish the corresponding benchmark for subsequent labeling.

[0038] The feeder label dispensing component 3 can work continuously to separate the label on the material from the backing paper at the edge of the label peeling plate 34, so that the adhesive side of the label is facing down, which is conducive to vacuum adsorption of the upper surface of the label by the labeling head 42. The material can be a roll of label tape with multiple labels attached. That is, the peeled label can stay at the tip of the label peeling plate 34, or be temporarily fixed by the labeling head 42 in preparation for labeling.

[0039] Once the color box is aligned and fixed in place by the positioning mechanism 22, the labeling component 4 is activated. At this time, the labeling head 42 moves to the feeder label dispensing component 3 to pick up or remove the tamper-evident label. Subsequently, the labeling head 42 moves to the target position above the color box fixed by the positioning mechanism 22 and performs the labeling action, such as pressing the label vertically down onto the upper surface of the color box to flatly and firmly attach the label to the designated position on the surface of the color box.

[0040] In this embodiment, the lifting and weighing assembly 1 and the positioning assembly 2 are arranged sequentially along the transport direction of the color box. The first conveying mechanism 11 of the lifting and weighing assembly 1 is used to transport the color box to the positioning assembly 2, the weighing mechanism 12 is used to weigh the color box, the second conveying mechanism 21 of the positioning assembly 2 is used to receive the color box from the first conveying mechanism 11, and the positioning mechanism 22 is used to position the color box on the second conveying mechanism 21. After the feeder label dispensing assembly 3 peels off the label, the labeling assembly 4 will attach the peeled label to the color box located at the positioning mechanism 22. In this way, the first conveying mechanism 11 of the lifting and weighing assembly 1 automatically transports the color box, the weighing mechanism 12 detects the weight of the color box, and after the second conveying mechanism 21 of the positioning assembly 2 receives the color box, the positioning mechanism 22 will correct the position of the color box, providing a positioning reference for subsequent labeling. Simultaneously, the feeder label dispensing component 3 continuously and automatically peels off the tamper-evident label, and the labeling component 4 immediately performs the labeling action after the positioning mechanism 22 completes calibration, affixing the label to the color box. This improves detection efficiency and accuracy, eliminates errors from manual operation, and enables seamless automation of weighing, positioning, and labeling in the color box production process. This reduces manpower consumption, increases operational efficiency, and improves labeling accuracy. Ultimately, this achieves the technical effects of reducing manpower consumption, increasing production efficiency, and improving product yield.

[0041] In one embodiment, the first conveying mechanism 11 includes a conveying driver 111 and a first conveyor belt 112. The conveying driver 111 includes a motor or a cylinder, and the first conveyor belt 112 is connected to the conveying driver 111. The conveying driver 111 drives the first conveyor belt 112 to rotate, so as to convey the color box to the positioning assembly 2. The first conveyor belt 112 may include a support frame, two rollers rotatably mounted on the support frame, and a conveyor belt respectively sleeved on the two rollers. The conveyor belt can be rotated clockwise or counterclockwise by driving one of the rollers to rotate. The weighing mechanism 12 includes a lifting driver 121, a lifting block 122, and a pressure sensor 123. The lifting driver 121 includes a motor or a cylinder. The lifting block 122 is connected to the lifting driver 121 and is located between two adjacent first conveyor belts 112. The lifting driver 121 drives the lifting block 122 to lift and lower, thereby lifting and lowering the color box. The pressure sensor 123 is installed on the lifting block 122. When the lifting driver 121 drives the lifting block 122 to separate the color box from the first conveyor belt 112, the pressure sensor 123 obtains the weight information of the color box. The first conveying mechanism 11 includes a conveyor driver 111 and a first conveyor belt 112 connected to the conveyor driver 111. The conveyor driver 111 drives the first conveyor belt 112 to rotate, automatically conveying the color box to the downstream positioning component 2 along the transport direction. During operation, the lifting driver 121 drives the lifting block 122 to rise. At this time, the lifting block 122 lifts the color box, causing the color box to separate from the rotating first conveyor belt 112. After the color box is stably lifted and disengaged from the first conveyor belt 112, the weight information of the color box can be accurately obtained by the pressure sensor 123. After weighing, the lifting driver 121 drives the lifting block 122 to descend, and the color box falls back onto the first conveyor belt 112, continuing to be conveyed to the positioning component 2. The lifting action completely removes the color box from the conveying surface on the first conveyor belt 112, eliminating the interference of the first conveyor belt 112 on the measurement, allowing the pressure sensor 123 to accurately measure the weight of the color box. At the same time, the pressure sensor 123 can be connected to an external display, which has a preset normal weight range for qualified color boxes. When the controller of the display compares the weight value of the color box obtained by the pressure sensor 123 with the above normal weight range, if the weight value of the color box is not within the above normal weight range, the display can show that there is a defective color box, or the warning light on the display can flash to remind the operator that there is a defective color box. The operator can then promptly activate the unloading mechanism 52 to remove the defective color box from the production line.

[0042] In some embodiments, the second conveying mechanism 21 includes a positioning driver 211 and two second conveyor belts 212. The two second conveyor belts 212 are connected to the positioning driver 211. The positioning driver 211 drives the second conveyor belts 212 to rotate, so as to convey the color box to the NG unloading assembly 5 described below. The positioning driver 211 includes a motor or a cylinder. For example, the second conveyor belts 212 are respectively mounted on two rollers located on the support frame. The positioning driver 211 drives the rollers to rotate, thereby driving the second conveyor belts 212 to rotate clockwise or counterclockwise. The positioning mechanism 22 includes at least two blocking members 221. The two blocking members 221 are respectively arranged on both sides of the two second conveyor belts 212. The two blocking members 221 are arranged at intervals between each other. The two blocking members 221 are used to restrict the color box from facing the second conveyor belts 212. The second conveying mechanism 21 may further include a handwheel adjustment module 228. The handwheel adjustment module 228 may include support blocks connected to the corresponding second conveyor belt 212. The support blocks provide support for the second conveyor belt 212. The two support blocks are slidably connected to a lead screw. By rotating the lead screw, the two support blocks move closer or further apart, thereby adjusting the spacing between the two second conveyor belts 212. That is, the second conveying mechanism 21 of the positioning assembly 2 includes a positioning driver 211 and two second conveyor belts 212 connected to the positioning driver 211. The positioning driver 211 drives the second conveyor belts 212 to rotate, so as to receive the color boxes conveyed from the first conveying mechanism 11 and further convey the color boxes to a designated position, such as the third conveying mechanism 51 in the NG unloading assembly 5 described below. The positioning mechanism 22 has two blocking components 221 respectively disposed on both sides of the two second conveyor belts 212. The two blocking components 221 are arranged at intervals to form a channel or positioning area to limit the lateral position of the color box on the second conveyor belt 212, so that the color box travels in the same direction as the second conveyor belt 212. For example, the blocking component 221 may include a motor and a push block connected to the push rod of the motor. The motor drives the push rod to move the push block toward or away from the color box, so as to adjust the position of the color box from both sides. For example, the two motors drive the push rod to extend the same distance to push the color box to the center position. Through the lateral guidance and constraint provided by the two blocking components 221, the lateral offset or skew that may occur in the color box during the transmission can be corrected, so that the color box is initially aligned with the preset path, providing an initial positioning reference for the subsequent labeling action.

[0043] In some embodiments, the positioning mechanism 22 in the automatic weighing and anti-tamper labeling device provided by this utility model further includes a lifting drive component 222, two positioning clamping components 223, a side push driver 224, and a side push rod 225. The lifting drive component 222 may include a cylinder or a motor, and the side push driver 224 may include a cylinder or a motor. The lifting drive component 222 is located between two second conveyor belts 212. The two positioning clamping components 223 are connected to the lifting drive component 222 and are arranged at intervals along the transport direction of the color box. The lifting drive component 222 drives the positioning clamping components 223 to rise to contact the color box, or the lifting drive component 222 drives the positioning clamping components 223 to fall to separate from the color box. The side push rod 225 is connected to the side push driver 224, and the side push driver 224 drives the side push rod 225 to move towards or away from the color box. A hollow area can be formed between the two second conveyor belts 212, allowing the two positioning clamping components 223 to rise or fall within this hollow area. Specifically, the positioning mechanism 22 also includes a lifting drive component 222 located between the two second conveyor belts 212, two positioning clamping components 223 connected to the lifting drive component 222, and a side push rod 225 connected to the side push driver 224. The positioning clamping components 223 can be vertically oriented rods. The two positioning clamping components 223 are spaced apart along the transport direction of the color box. The lifting drive component 222 can drive the positioning clamping components 223 to rise, allowing the lifting drive component 222 to contact the color box placed on the second conveyor belt 212, or it can drive the positioning clamping components 223 to fall, separating the positioning clamping components 223 from the color box. When the lifting drive component 222 contacts the color box placed on the second conveyor belt 212, and the color box rises to separate from the second conveyor belt 212, the side push driver 224 can then drive the side push rod 225. The side push rod 225 moves towards the color box to push it to the other side, adjusting its position. Alternatively, the side pusher 224 drives the side push rod 225 away from the color box. At this time, the lifting drive component 222 drives the positioning clamping component 223 to descend, separating the positioning clamping component 223 from the color box. Simultaneously, the adjusted color box is placed on the second conveyor belt 212. The positioning clamping component 223, driven by the lifting drive component 222, actively clamps or releases the color box in the Z direction, i.e., the lifting direction. The two spaced clamping components provide longitudinal positioning points in the transport direction. At the same time, the side pusher 224 and the side push rod 225 can provide an active correction force perpendicular to the transport direction. Through the coordinated action of the lifting drive component 222 and the side pusher 224, the position of the color box in the horizontal plane can be more precisely corrected and securely clamped.

[0044] In some embodiments, the positioning mechanism 22 in the automatic weighing and tamper-evident label applicator provided by this utility model further includes a pressing driver 226 and a pressing arm 227. The pressing driver 226 may include a motor or a cylinder. The pressing arm 227 is connected to the pressing driver 226 and is located between two positioning clamping components 223. The pressing driver 226 drives the pressing arm 227 to move up and down. The projection of the pressing arm 227 onto the color box along the direction close to the color box is located on the color box. That is, the positioning mechanism 22 may also include a pressing driver 226 and a pressing arm 227 connected to the pressing driver 226, with the pressing arm 227 located between two positioning clamping components 223. The pressure drive 226 drives the pressure arm 227 to move up and down. When the pressure arm 227 moves along the direction close to the color box, the projection of the pressure arm 227 on the color box is located in the surface area of ​​the color box. It can effectively press the color box down to prevent warping or deformation of the color box during positioning. The downward pressing force can perform micro-shaping on the color box, that is, prevent the upper surface of the color box from bulging. At the same time, it can enhance the overall stability of the color box after positioning, so as to eliminate the micro-movement that may be caused by the deformation or instability of the color box itself, and improve the labeling accuracy.

[0045] In some embodiments, the automatic weighing and tamper-evident labeling device provided by this utility model further includes an NG unloading component 5. A positioning component 2 is located between the lifting weighing component 1 and the NG unloading component 5. A second conveying mechanism 21 transports the color boxes to the NG unloading component 5, which is used to remove defective products. By arranging the positioning component 2 between the lifting weighing component 1 and the NG unloading component 5, the second conveying mechanism 21 of the positioning component 2 can transport the color boxes to the NG unloading component 5. The NG unloading component 5 can be used to automatically remove or sort out products detected as defective from the production line. By setting the NG unloading component 5 downstream of the positioning component 2, color boxes that are determined to be defective after weighing can be automatically transported to the NG unloading component 5 by the second conveying mechanism 21 for processing, avoiding manual identification and handling of defective products, reducing the required manpower, and preventing defective products from being mixed with qualified products.

[0046] In some embodiments, the NG unloading assembly 5 includes a third conveying mechanism 51 and an unloading mechanism 52. The third conveying mechanism 51 includes an unloading driver 511 and multiple unloading conveyor belts 512. The unloading driver 511 may include a motor or a cylinder. The multiple unloading conveyor belts 512 are interconnected with the unloading driver 511. The unloading driver 511 drives the multiple unloading conveyor belts 512 to rotate, thereby moving the color box away from the positioning assembly 2. For example, the unloading conveyor belts 512 are respectively mounted on two rollers located on the support frame. The unloading driver 511 drives the rollers to rotate, thereby driving the unloading conveyor belts 512. The feeding mechanism 52, which rotates clockwise or counterclockwise, includes a lifting roller 522, a lifting driver 523, and multiple flow strips 521. The lifting driver 523 includes a motor or cylinder. The lifting roller 522 is positioned between two adjacent feeding conveyor belts 512. The lifting driver 523 is connected to the lifting roller 522. When a defective product appears, the lifting driver 523 drives the lifting roller 522 to rise until it contacts the defective product. At this time, the rotation of the lifting roller 522 moves the defective product onto the flow strip 521, and the defective product flows out along the flow strip 521. The lifting roller 522 may include a support base connected to the lifting rod of the lifting driver 523, and a rotary motor mounted on the support base. The rotary motor is connected to the roller and can drive the roller to rotate clockwise or counterclockwise in the horizontal plane. The feeding driver 511 drives the feeding conveyor belt 512 to rotate, which can transport the labeled and qualified color boxes in the direction away from the positioning component 2. Furthermore, when a defective product is detected, such as due to an abnormal weighing result, the lifting driver 523 can drive the lifting roller 522 to rise until it contacts the bottom surface of the defective box. The lifting roller 522 will then rotate, pushing the box laterally onto the flow chart 521. The defective box will automatically slide off the production line along the inclined surface of the flow chart 521. Through the active lifting and rotation of the lifting roller 522, defective products can be transferred to the flow chart 521 channel in a timely manner, achieving automatic sorting and physical isolation of defective products. This allows defective products to be quickly removed from the production line, preventing defective boxes from mixing with qualified products and affecting the yield rate, while also reducing labor costs.

[0047] In some embodiments, the feeder label dispensing assembly 3 includes a feeder bracket 31, a feeding driver 32, a feeding drum 33, a label peeling plate 34, a receiving driver 35, and a receiving drum 36. The feeding driver 32 may include a motor or a cylinder, and the receiving driver 35 may include a motor or a cylinder. The feeding driver 32 is mounted on the feeder bracket 31, and the feeding drum 33 is connected to the feeding driver 32. The material with the label is wound around the feeding drum 33. The label peeling plate 34, the receiving driver 35, and the receiving drum 36 are respectively mounted on the feeder bracket 31. The receiving driver 35 drives the receiving drum 36 to rotate, so that the feeding driver 32 drives the feeding drum 33 to rotate to feed the material. The material bends backward above the label peeling plate 34 and enters below the label peeling plate 34. The material is located between the label and the label peeling plate 34, and the material below the label peeling plate 34 is wound around the receiving drum 36. The feeder label dispensing assembly 3 may also include a pressing mold component 37. Driven by the pressing mold component 37, a pressure plate is pressed to tighten the backing paper when the label is separated from the label peeling plate 34, preventing the backing paper from loosening or shifting. Specifically, the labeled material is wound onto the feeding drum 33. The feeding driver 32 drives the feeding drum 33 to release the material. If a rotating drum is installed on the feeder bracket 31 to guide the material's direction, the material can bend in the opposite direction as it passes above the label peeling plate 34, entering below. The label separates from the backing paper at the edge of the label peeling plate 34. At this point, the label remains on the surface of the label peeling plate 34, awaiting retrieval, while the backing paper continues to wind around below the label peeling plate 34 and is recycled by the receiving drum 36 driven by the receiving driver 35. This achieves continuous automatic label peeling and backing paper recycling. The reverse tension generated at the edge of the label peeling plate 34 separates the label from the backing paper, improving the stability and continuity of the peeling action.

[0048] In some embodiments, the labeling assembly 4 includes a moving mechanism 41, a labeling head 42, and a rolling film driver 43. The labeling head 42 and the rolling film driver 43 are respectively mounted on the moving mechanism 41. The moving mechanism 41 drives the labeling head 42 to approach the peeled label to adsorb the label and move it to the surface of the color box. The rolling film driver 43 is used to press the label onto the surface of the color box. The rolling film driver 43 may include a cylinder and a rolling rod. The cylinder can drive the rolling rod to roll in a horizontal plane. The labeling head 42 may be connected to an air pump to generate vacuum adsorption. The labeling assembly 4 may also include a CCD module 431. The CCD module 431 may be mounted on the mounting bracket 49. The CCD module 431 can detect the label attachment status on the surface of the color box in real time, or position the surface of the color box to attach the label to the target position on the surface of the color box. The labeling head 42 is moved by the moving mechanism 41 to the label peeled off by the feeder label dispensing component 3, and then the label is picked up by vacuum adsorption. The moving mechanism 41 then positions the labeling head 42 to the corresponding coordinates on the surface of the color box that has been positioned and corrected. At this time, the rolling film driver 43 is activated to press the label firmly onto the surface of the color box and complete the rolling and pasting. The uniform pressure applied by the rolling film driver 43 is conducive to the bubble-free application of the label, eliminating wrinkles and air bubbles, and achieving a high degree of firmness in the adhesion between the label and the surface of the color box.

[0049] In some embodiments, the moving mechanism 41 includes a gantry 44, a Y-axis module 45, an auxiliary rail 46, an X-axis module 47, a Z-axis module 48, and a mounting frame 49. The Y-axis module 45 and the auxiliary rail 46 are respectively mounted on the gantry 44. The X-axis module 47 is connected to the Y-axis module 45 and is slidably connected to the auxiliary rail 46, such as the auxiliary rail 46 being slidably connected to the housing of the X-axis module 47. The Y-axis module 45 is used to drive the X-axis module 47 to move along the Y-axis direction. The Z-axis module 48 is connected to the X-axis module 47 and is used to drive the Z-axis module 48 to move along the X-axis direction. The mounting frame 49 is mounted on the Z-axis module 48 and is used to drive the mounting frame 49 to move along the Z-axis direction. The labeling head 42 and the rolling film driver 43 are respectively mounted on the mounting frame 49. The X-axis module 47 may include a linear motor, or a servo motor and a ball screw. The servo motor drives the ball screw to rotate, and the ball screw converts the rotational motion into linear motion, so that the X-axis module 47 drives the Z-axis module 48 to move along the X-axis direction. Since the Y-axis module 45 and the Z-axis module 48 have the same structure and principle as the X-axis module 47, they will not be described in detail here.

[0050] In some embodiments, the automatic weighing and anti-tampering labeling device provided by this utility model further includes a frame assembly 6.
