Description

Technical Field

[0001] This invention relates to the field of labeling machine technology, and in particular to a labeling positioning and adjustment mechanism and method for automobile door locks. Background Technology

[0002] When labeling car door locks, a flat labeling machine is usually used to paste rolls of self-adhesive labels onto the surface of the car door lock. The labeling machine is adjusted according to the type of car door lock and label. Then, the specially made label is automatically pasted onto the car door lock at a predetermined position and angle, making the product labeling more aesthetically pleasing and achieving the purpose of packaging the car door lock. Existing labeling machines can process a large number of labels in a short time, improving production efficiency.

[0003] For example, CN112591249A discloses a fully automatic labeling machine, including a frame, a conveying mechanism for moving a PCB board on the frame, at least one label feeding mechanism for feeding labels on one side of the frame, a Y-axis transmission mechanism on the upper side of the conveying mechanism, an X-axis transmission mechanism on the upper side of the Y-axis transmission mechanism, a label attaching mechanism on the upper side of the X-axis transmission mechanism, the label attaching mechanism including an image inspection mechanism and a Z-axis transmission mechanism that can move up and down, and a labeling head for picking up labels on the lower side of the Z-axis transmission mechanism. The position of the label after it is removed can be controlled by the Y-axis transmission mechanism, the X-axis transmission mechanism and the Z-axis transmission mechanism.

[0004] Based on the above solution, fully automatic labeling machines can automatically label items. However, when adjusting the peeling position according to the specifications of different labels, since the peeling position is fixed, it is necessary to manually pull the label to adjust the peeling position. The operation is relatively complicated and the accuracy is low, which can easily affect the labeling effect.

[0005] Therefore, it is necessary to solve the above problems by means of a car door lock label positioning adjustment mechanism and adjustment method. Summary of the Invention

[0018] A method for adjusting the positioning and adjustment mechanism of a car door lock label, the specific steps of which are as follows:

[0019] S1. First, adjust the workpiece feeding speed and labeling position through the labeling machine components, and then adjust the label transmission speed and transmission position through the label transmission components.

[0020] S2. Secondly, by cooperating with the label peeling component and the adjustment component, the peeling position and angle of labels of different specifications can be adjusted.

[0021] S3. Then, the label suction and pressing components and the labeling machine components work together to apply and press labels onto the car door locks.

[0022] S4. Finally, the labeling quality of the car door locks is inspected by the labeling inspection component. Based on the inspection results, the unloading and conveying component sorts and stores the labeled car door locks.

[0023] The technical effects and advantages of this invention are as follows:

[0024] 1. This invention utilizes a label transmission assembly and a label peeling assembly to ensure normal label transmission and automatic label peeling. Then, a labeling machine assembly and a label suction and pressing assembly work together. A photoelectric sensor detects and a servo motor controls the rotation angle of the turntable, enabling precise positioning of the car door lock during labeling or pressing. This facilitates the label suction and pressing assembly's positioning, labeling, and pressing of the car door lock. A labeling detection assembly then inspects the labels on the car door locks. Based on the inspection results, a material feeding and conveying assembly sorts and collects qualified and unqualified labeled car door locks. During the car door lock labeling process, automatic positioning and control of feeding, labeling, inspection, and unloading are achieved, reducing manual intervention and improving work efficiency.

[0025] 2. This invention uses the pressure difference on the pressure sensor to intuitively reflect the flexibility of the label during the transmission process. Based on the different flexibility of the label, the rotary motor drives the eccentric wheel and the connecting rod frame to rotate together. This causes the connecting rod frame to move the slider along the arc track, causing one end of the adjusting plate to move with the slider. This changes the tilt angle of the adjusting plate, thereby enabling adaptive adjustment of the peeling angle between the label peeling plate and the adjusting plate. This improves the matching degree between the label flexibility and the peeling angle, facilitating the quick and smooth peeling of the label.

[0026] 3. To prevent the label from sag after peeling, the present invention minimizes the peeling amount between the label and the backing paper by adjusting the controller to the minimum. This involves minimizing the horizontal distance between the peeling plate and the fiber optic sensor. The controller controls the retraction of the adjusting cylinder, which, through the cooperation of the push plate, slide plate, and peeling plate, reduces the horizontal distance between the peeling plate and the fiber optic sensor. This reduction in the horizontal distance compensates for any sagging after label peeling. Within this flexible range, the label directly blocks the fiber optic sensor after peeling, preventing sagging or drooping. This significantly improves the accuracy of label peeling and enhances subsequent labeling quality. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] First Embodiment

[0039] like Figures 1 to 3 As shown, an automotive door lock labeling positioning and adjustment mechanism of the present invention includes a labeling machine assembly 1, a label transmission assembly 2, a label peeling assembly 3, an adjustment assembly 4, a label suction and pressing assembly 5, a labeling detection assembly 6, and a material feeding and conveying assembly 7. The label transmission assembly 2, the label peeling assembly 3, the adjustment assembly 4, and the label suction and pressing assembly 5 are all disposed on one side of the labeling machine assembly 1, and the adjustment assembly 4 is disposed below the label peeling assembly 3. The labeling detection assembly 6 is disposed between the label suction and pressing assembly 5 and the material feeding and conveying assembly 7.

[0040] like Figure 4 As shown, the label transmission assembly 2 includes a label holder 201, a label tube 202 fixedly mounted above the label holder 201, a take-up tube 209 fixedly mounted on one side of the label holder 201, a first traction roller 203, a second traction roller 204, a first guide roller 205, a second guide roller 206 and a roller 208 mounted on the surface of the label holder 201, with the second traction roller 204 located below the first traction roller 203, and the roller 208, the first guide roller 205 and the second guide roller 206 all located below the second traction roller 204. A label strip 210 is movably mounted on the surface of the label tube 202, a guide plate 207 is fixedly mounted at one end of the label holder 201, the guide plate 207 is fixedly mounted at one end of the label peeling assembly 3, an optical fiber support 211 is mounted on one side of the label holder 201, and an optical fiber sensor 212 is fixedly mounted above the optical fiber support 211.

[0041] like Figure 5 As shown, the label peeling assembly 3 includes a placement plate 301, a sliding plate 304 is movably disposed at one end of the placement plate 301, a label peeling plate 305 is fixedly disposed at the end of the sliding plate 304 away from the placement plate 301, an adjusting plate 306 is assembled at one end of the label peeling plate 305, a limiting seat 302 is movably disposed above the placement plate 301, a side plate 303 is fixedly disposed below the placement plate 301, and a limiting hole is provided at the position where the limiting seat 302 connects with the placement plate 301.

[0042] In use, the label tape 210 is wound around the label transmission assembly 2, and then the motor drives the transmission mechanism to position and pull the label tape 210 through the first traction roller 203 and the second traction roller 204. Under the guidance of the first guide roller 205 and the second guide roller 206, the transmission process of the label tape 210 is guided and positioned, so that the label tape 210 automatically moves to the peeling position. The label tape 210 is limited by the limit seat 302 to prevent the label tape 210 from shifting position when moving on the placement plate 301, which would affect the subsequent labeling quality. Then, the peeling plate 305 and the adjusting plate 306 work together to peel the label off the backing paper on the label tape 210. As the label and backing paper are peeled off, the peeling end of the label will block the fiber optic sensor 212. The controller will then control the label suction and pressing assembly 5 to complete the adsorption and picking of the label. The backing paper passes through the adjusting plate 306, the guide plate 207 and the roller 208 in sequence and is finally collected by the take-up drum 209.

[0043] like Figure 8 As shown, the label suction and pressing assembly 5 includes a label suction cylinder 504 and a label pressing cylinder 509. A label pressing urethane adhesive 510 is fixedly installed at the lower end of the label pressing cylinder 509. A label suction plate 505 is fixedly installed at the lower end of the label suction cylinder 504. A rotating frame 503 is fixedly installed at one end of the label suction cylinder 504. A label suction frame 501 is movably installed below the rotating frame 503. A label suction motor 502 is fixedly installed inside the label suction frame 501. One end of the output shaft of the label suction motor 502 is fixedly installed at the bottom end of the rotating frame 503. A vacuum generator 506 is fixedly installed above the rotating frame 503. An air pipe 507 is fixedly installed on the surface of the vacuum generator 506. A negative pressure gauge 508 is fixedly installed at one end of the vacuum generator 506.

[0044] like Figure 2 , Figure 8 As shown, the labeling machine assembly 1 includes a frame 101. A feed window 102 is fixedly provided on the surface of the frame 101. A support plate 103 is fixedly provided inside the frame 101. A servo motor 104 is fixedly provided above the support plate 103. A turntable 105 is fixedly provided at one end of the output shaft of the servo motor 104. A car lock holder 106 is fixedly provided on the surface of the turntable 105. A mounting plate 107 is fixedly provided above the support plate 103. A photoelectric sensor 108 is fixedly provided on the surface of the mounting plate 107. The mounting plate 107 is located below the turntable 105.

[0045] In use, the car door lock to be labeled is placed on the lock holder 106 on the surface of the turntable 105 through the feed window 102. When the photoelectric sensor 108 detects a car door lock to be labeled on the lock holder 106, the turntable 105 is rotated to a preset angle to the labeling position by driving the servo motor 104. Then, the label suction motor 502 drives the rotating frame 503 to rotate 180 degrees counterclockwise, so that the label suction cylinder 504 and the label suction plate 505 move together with the rotating frame 503 to the label suction position. Under the action of the vacuum generator 506, the label suction plate 505 is in a negative pressure suction state, and then the label is suctioned. The label is held in place by plate 505. Then, the label suction motor 502 drives the rotating frame 503 to rotate clockwise to 180 degrees, causing the label suction cylinder 504 to move the label suction plate 505 downwards to stick the label onto the car door lock. Then, the servo motor 104 drives the turntable 105 to rotate by a preset angle, moving the car door lock with the label to the label pressing position. Then, the label pressing cylinder 509 drives the label pressing adhesive 510 to move downwards to press and fix the label on the surface of the car door lock. Finally, the servo motor 104 drives the turntable 105 to rotate by a preset angle, moving the labeled car door lock to the labeling detection position to wait for detection.

[0046] like Figure 8 As shown, the labeling detection component 6 includes a mounting frame 601, a display 602 is fixedly mounted on the top of the mounting frame 601, a mounting base 603 is fixedly mounted on the surface of the mounting frame 601, a camera 604 is fixedly mounted on one end of the mounting base 603, and a light detector 605 is fixedly mounted on one side of the mounting frame 601, with the light detector 605 positioned below the camera 604.

[0047] In use, the light emitted by the light detector 605 illuminates the label on the surface of the car door lock, and then the camera 604 captures the image and transmits it to the display 602. The data is analyzed to determine whether the labeling quality is up to standard. The detection results are then transmitted to the controller via an electrical signal, causing the unloading conveyor component 7 to classify and unload the car door locks according to the detection results.

[0048] like Figure 9 As shown, the unloading conveying assembly 7 includes an unloading frame 701, an unloading motor 702 fixedly mounted on the unloading frame 701, a rotating frame 703 fixedly mounted on one end of the output shaft of the unloading motor 702, an unloading cylinder 704 fixedly mounted on one end of the rotating frame 703, an unloading gripper 705 fixedly mounted on the lower end of the unloading cylinder 704, a conveyor belt 708 mounted on one end of the unloading frame 701, an unloading hopper 709 fixedly mounted on one end of the conveyor belt 708, a waste conveying pipe 706 mounted on one side of the conveyor belt 708, and a waste collection frame 707 mounted below the waste conveying pipe 706.

[0049] In use, the feeding cylinder 704 and the feeding gripper 705 work together to grab the car door lock on the turntable 105. When the labeling detection component 6 detects a qualified result, the feeding motor 702 drives the rotating frame 703 to rotate by a preset angle, so that the feeding gripper 705 places the qualified car door lock onto the conveyor belt 708 and transports it through the feeding hopper 709. When the labeling detection component 6 detects a failed result, the feeding motor 702 drives the rotating frame 703 to rotate by a preset angle, so that the feeding gripper 705 puts the failed car door lock into the waste conveying pipe 706 and collects it into the waste collection box 707. The labeling detection component 6 and the feeding conveying component 7 work together to facilitate the classification and collection of qualified and unqualified labeled car door locks.

[0050] In summary, by setting the label transmission component 2 and the label peeling component 3 to work together, automatic label peeling is facilitated. Then, by cooperating with the labeling machine component 1 and the label suction and pressing component 5, the photoelectric sensor 108 detects and the servo motor 104 controls the rotation angle of the turntable 105, enabling precise positioning of the car door lock during labeling or pressing. This facilitates the label suction and pressing component 5 in positioning, labeling, and pressing the car door lock. Then, the label detection component 6 detects the labels on the car door lock. Based on the detection results, the unloading conveyor component 7 sorts and collects qualified and unqualified labeled car door locks. In the process of labeling car door locks, automatic positioning and control of feeding, labeling, detection, and unloading are achieved, reducing manual intervention and improving work efficiency.

[0051] Second Embodiment

[0052] During the operation of the first embodiment, it was found that due to the different specifications of the labels, the materials used in the actual production of the labels will also be different. This will result in different flexibility of the produced labels, and the different flexibility will make the labels have different degrees of difficulty in peeling. Since the label peeling component 3 relies on the peeling force generated by the angle between the adjusting plate 306 and the backing paper to make the label detach from the backing paper, the less flexible the label, the softer the label, and the more difficult it is to peel the label from the backing paper, and vice versa. However, the angle between the label peeling plate 305 and the adjusting plate 306 in the label peeling component 3 is fixed. This results in a fixed angle between the adjusting plate 306 and the backing paper. Therefore, in the actual label peeling process, the different materials of the labels may cause peeling failure, thereby affecting the normal operation of the labeling work. Based on this, this application proposes the following improvement:

[0053] like Figure 6As shown, the adjustment assembly 4 includes a rotary motor 401. An eccentric wheel 402 is fixedly mounted on one end of the output shaft of the rotary motor 401. A connecting rod frame 403 is fixedly mounted on the surface of the eccentric wheel 402. A slider 404 is movably hinged to one end of the connecting rod frame 403. An arc-shaped track 405 is movably mounted on one side of the slider 404. The end of the slider 404 away from the connecting rod frame 403 is movably hinged to one end of the adjustment plate 306. A fixed seat 406 is fixedly mounted below the label peeling plate 305, and one end of the arc-shaped track 405 is fixedly mounted below the fixed seat 406. A fixed frame 407 is fixedly mounted on the surface of the rotary motor 401. The fixed frame 407 is fixedly mounted below the label peeling plate 305. A pressure sensor adapted to the label tape 210 is fixedly mounted on the outer wall of the first guide roller 205.

[0054] In use, the first guide roller 205 is in constant contact with the label tape 210 during its conveying process, providing tension. During normal conveying, the label tape 210 exerts tension pressure on the first guide roller 205, denoted as F0. Because the label is attached to the surface of the label tape 210, when the label tape 210 passes over the first guide roller 205, the pressure sensor aligns with the label tape 210. This causes the label on the label tape 210 to exert additional pressure on the pressure sensor, with the pressure value recorded as F1. When the label has low flexibility, the pressure value exerted by the label tape 210 overcoming the label's deflection remains unchanged. However, when the label has high flexibility... When the label becomes larger, its own flexibility increases the tension of the label tape 210. This requires the label tape 210 to overcome the label's own flexibility, resulting in an increase in the pressure value acting on the pressure sensor. The greater the label's flexibility, the greater the pressure value acting on the pressure sensor through the label tape 210. When the label passes over the first guide roller 205, the force acting on the pressure sensor is the tension of the label tape 210 during transmission. Therefore, the pressure on the pressure sensor only changes when the label and the first guide roller 205 are aligned. The difference between F1 and F0 corresponds one-to-one with the label's flexibility, so the difference between F1 and F0 can be used to intuitively reflect the label's flexibility during transmission.

[0055] Since the flexibility of the label affects label dispensing, the tilt angle of the adjusting plate 306 is changed in real time based on the label flexibility detection. Specifically, according to the different flexibility of the label, the rotary motor 401 drives the eccentric wheel 402 and the connecting rod frame 403 to rotate together. This causes the connecting rod frame 403 to drive the slider 404 to move along the arc track 405, thus causing one end of the adjusting plate 306 to move with the slider 404, thereby changing the tilt angle of the adjusting plate 306. This allows for adaptive adjustment of the peeling angle between the label peeling plate 305 and the adjusting plate 306, improving the matching degree between the label flexibility and the peeling angle, facilitating fast and smooth label dispensing. Specifically:

[0056] When the difference between F1 and F0 is less than the minimum threshold, it indicates that although the label is flexible, its flexibility is very small and insufficient to achieve the peeling operation using the angle between the peeling plate 305 and the adjusting plate 306. Furthermore, even when the angle between the peeling plate 305 and the adjusting plate 306 is at its minimum, the label cannot be effectively peeled off. This indicates that the label has poor peelability, and the controller activates the alarm. Since the label is not peelable, the staff promptly replaces it.

[0057] When the difference between F1 and F0 is greater than the minimum threshold but less than the first threshold, it indicates that although the label is flexible and within the peelable range of the adjustment component 4, its flexibility is insufficient to support the label in a horizontal state. This will cause the peeled end of the label to be in a drooping state. Since there is a distance between the label peeling plate 305 and the fiber optic sensor 212, the peeled label cannot accurately correspond to the fiber optic sensor 212. Furthermore, once the label is in a drooping state, the correspondence between the fiber optic sensor 212 and the label will lag, causing the label suction and pressing component 5 to be unable to accurately correspond to the label. Although the suction operation can be achieved, the position has already shifted, which will seriously affect the subsequent labeling quality.

[0058] To solve the above problems, such as Figure 7 As shown, a push plate 307 is fixedly installed below the slide plate 304, and an adjusting cylinder 308 is fixedly installed at one end of the push plate 307.

[0059] In use, when the difference between F1 and F0 is greater than the minimum threshold but less than the first threshold, in order to avoid the label from drooping after peeling, the controller minimizes the amount of peeling between the label and the backing paper. That is, the horizontal distance between the peeling plate 305 and the fiber optic sensor 212 is adjusted to the minimum. The controller controls the adjusting cylinder 308 to retract, which will reduce the horizontal distance between the peeling plate 305 and the fiber optic sensor 212 through the cooperation of the push plate 307, the slide plate 304 and the peeling plate 305. In this way, by reducing the horizontal distance between the peeling plate 305 and the fiber optic sensor 212, the drooping allowance after the label is peeled is compensated. In this flexible range, the label will directly block the fiber optic sensor 212 after peeling. At this time, the label will not droop or swing, which greatly improves the accuracy of the label peeling and improves the subsequent labeling quality.

[0060] It is worth noting that when the label size increases, in order to ensure that the label peeling amount is sufficient for the label to be successfully peeled off and adsorbed by the label suction and pressing component 5, the distance between the label peeling plate 305 and the fiber optic sensor 212 needs to be adjusted according to the label size. By setting the sliding plate 304, the peeling position of the label peeling plate 305 can be adjusted according to the actual situation, that is, the peeling amount of the label and the backing paper can be adjusted. The peeling amount is the horizontal distance between the label peeling plate 305 and the fiber optic sensor 212. When the peeling amount of the label and the backing paper reaches the preset value, the fiber optic sensor 212 detects and transmits an electrical signal to the label suction and pressing component 5, so that the label suction and pressing component 5 performs label suction processing on the label peeling plate 305.

[0061] It is worth noting that since the label suction and pressing assembly 5 uses the position of the fiber optic sensor 212 as the reference point when adsorbing the label, the movement of the label peeling plate 305 only changes the peeling position of the label and has no effect on the correspondence between the label and the label suction and pressing assembly 5.

[0062] When the difference between F1 and F0 is greater than the first threshold but less than the highest threshold, it indicates that the label is flexible and its flexibility is within the standard range and within the adjustable range of the adjustment component 4. The controller controls the rotary motor 401 according to the difference between F1 and F0, causing it to drive the adjustment plate 306 to deflect to the corresponding angle. In this way, the label and backing paper can be peeled off by using the angle between the peeling plate 305 and the adjustment plate 306. That is, the larger the difference between F1 and F0, the greater the flexibility of the label itself, and the easier it is to peel off. Therefore, the controller controls the rotary motor 401 to drive the adjustment plate 306 to deflect to a smaller angle, which makes the angle between the peeling plate 305 and the adjustment plate 306 increase accordingly, but it can still meet the peeling operation between the label and the backing paper at this time.

[0063] It is worth noting that when the difference between F1 and F0 is greater than the first threshold but less than the highest threshold, it indicates that the label is flexible enough and will not bend or droop even after the label is separated. Therefore, in this process, the controller only needs to ensure that the included angle between the label peeling plate 305 and the adjusting plate 306 is at the minimum state within this range to meet the peeling needs of all labels within this range.

[0064] When the difference between F1 and F0 is greater than the highest threshold, it indicates that the label is too flexible and the first guide roller 205 and the second guide roller 206 cannot effectively guide and tension the label strip 210. At the same time, the label roll 202 also has difficulty winding the label strip 210. Therefore, the controller controls the alarm to sound an alarm, prompting the staff that the label is in a non-working state and needs to be replaced and maintained in time.

[0065] It is worth noting that in the actual labeling process, when the difference between the values ​​F1 and F0 detected by the pressure sensor becomes smaller, it indicates that the label's flexibility has decreased. At this time, if the peeling angle between the peeling plate 305 and the adjusting plate 306 is maintained in the current state, it is impossible to effectively peel off the label with reduced flexibility. Therefore, the controller controls the rotary motor 401 to rotate, driving the adjusting plate 306 to rotate in the direction of the peeling plate 305, reducing the peeling angle between the peeling plate 305 and the adjusting plate 306 to adapt to the need for peeling the label with reduced flexibility. Therefore, the tilt angle of the adjusting plate 306 can be adjusted according to the different flexibility of the label, making it easier for the label to separate from the backing paper and smoothly dispense the label.
