Description

Technical Field

[0001] This invention relates to the field of automated production technology of optical modules, and in particular to an automated labeling device and method for optical modules. Background Technology

[0002] With the rapid development of the optical communication field, the demand for optical modules has grown rapidly in recent years. Before leaving the factory, optical modules need to be labeled to record relevant information. Currently, labeling of optical modules is mostly done manually, which has the following drawbacks: 1. Manual labeling is difficult, relying on visual alignment, especially since temporary labels are much smaller than the module label frame, leading to significant variations in label placement. Large misalignments can affect the product's appearance and subsequent automatic scanning processes. Repeated relabeling can also reduce label adhesion, rendering the label ineffective; 2. Manual labeling wastes manpower, contradicting the development direction of intelligent manufacturing. Furthermore, it requires manual operation throughout the process, consuming long hours and resulting in low labor utilization. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an automatic labeling device for optical modules, comprising a frame, and further comprising a loading / unloading mechanism, a label peeling mechanism, a material handling assembly, and a vision positioning mechanism disposed on the frame. The loading / unloading mechanism includes a drive mechanism for switching a material tray between a loading / unloading position and a labeling position. The label peeling mechanism is used to peel labels off the backing paper, and the label peeling mechanism is connected to a label supply mechanism for supplying labels. The material handling assembly includes a suction mechanism capable of picking up and applying labels, and a conveying mechanism for driving the suction mechanism to pick up labels from the label peeling mechanism and apply labels at the labeling position.

[0004] Furthermore, the loading and unloading mechanism also includes a hopper assembly and a hopper lifting mechanism. The hopper assembly is provided with multiple material trays, and the material trays are arranged sequentially from bottom to top. The hopper lifting mechanism is connected to the hopper assembly and is used to drive the hopper assembly to lift and lower so that one of the material trays moves to the loading / unloading position.

[0005] Furthermore, the hopper assembly includes a box body with an opening on the side facing the drive mechanism. The box body has multiple layers of slide grooves distributed sequentially from bottom to top. The slide grooves are parallel to the direction of action of the drive mechanism. The material trays are slidably disposed on the slide grooves, and each material tray corresponds to each layer of slide groove.

[0006] Furthermore, the loading and unloading mechanism also includes an identification unit for identifying the optical module. The identification unit is positioned facing the hopper assembly, and the hopper assembly has an identification window adapted to the identification unit at the position corresponding to each of the material trays.

[0007] Furthermore, the loading and unloading mechanism also includes a flattening mechanism, which is located between the loading / unloading position and the labeling position. The flattening mechanism includes liftable pressure rollers suspended for applying pressure to the material tray that moves between the loading / unloading position and the labeling position.

[0008] Furthermore, the material tray includes a base plate and a blister box inner support disposed on the base plate for supporting the blister box. The blister box inner support is detachably connected to the base plate. A gripper groove is provided on the side of the base plate facing the driving mechanism. The driving mechanism includes grippers adapted to the gripper groove.

[0009] Furthermore, the label peeling mechanism includes a guide for guiding the label and a label winding assembly for winding the backing paper, arranged sequentially along the label running direction. A label separating plate for separating the label and the backing paper is provided on one side of the guide.

[0010] Furthermore, the suction mechanism includes a fixed plate, a suction nozzle lifting mechanism, a rotating mechanism, and a suction nozzle. The fixed plate is mounted on the conveying mechanism, the suction nozzle lifting mechanism is disposed on the fixed plate, the rotating mechanism is disposed at the output end of the suction nozzle lifting mechanism, and the suction nozzle is disposed on the rotating mechanism.

[0011] Furthermore, it also includes a control unit. The visual positioning mechanism includes a first identification mechanism mounted on the frame for identifying the label after it has been picked up, and a second identification mechanism mounted on the conveying mechanism for identifying the optical module. The first identification mechanism, the second identification mechanism, the driving mechanism, the conveying mechanism, and the picking mechanism are electrically connected to the control unit.

[0012] On the other hand, the present invention also provides an automatic labeling method for optical modules, which, based on the implementation of the aforementioned automatic labeling equipment for optical modules, includes the following steps:

[0013] The material tray is dispatched from the warehouse, and the drive mechanism sends the material tray to the labeling position;

[0014] The label removal agency performs the label removal operation;

[0015] The suction mechanism picks up the label from the label peeling mechanism and moves it to the labeling position for labeling by the transport mechanism;

[0016] After labeling is completed, the drive mechanism will send the material tray to the upper and lower material positions.

[0017] The automatic labeling equipment for optical modules provided by this invention has a hopper assembly that can accommodate multiple material trays. Different types of blister packs can be placed on the material trays, achieving uniformity in the hopper for different optical modules. Driven by a hopper lifting mechanism, the hopper assembly moves the material trays to the upper and lower material positions. The material trays switch between the upper / lower material position and the labeling position under the action of the driving mechanism, realizing automatic loading and unloading of optical modules. A flattening mechanism assists in flattening the blister packs, ensuring consistent product height within the blister packs, improving labeling quality. Furthermore, after labeling, it can act on the optical modules to further adhere the labels, improving label adhesion reliability. A material handling assembly is used to transfer labels between the label peeling mechanism, the visual positioning mechanism, and the material trays at the labeling position. The suction mechanism, driven by the conveying mechanism, can move along the X and Y axes. The suction nozzle of the suction mechanism can be raised and lowered to move along the X, Y, and Z axes. At the same time, the suction nozzle is connected to a rotating mechanism, which can rotate under the action of the rotating mechanism to adjust the position of the label. Under the action of the vision positioning mechanism, it ensures the consistency of the labeling position and improves the labeling effect. The label peeling mechanism is used to automatically separate the label and the backing paper. The label separation plate of the label peeling mechanism is set close to the label separation port, which can realize the universality of roll labels and long sheet labels. The material bin assembly and the label peeling mechanism are respectively set on both sides of the frame, which facilitates manual replacement of the material tray in the material bin assembly and manual label replacement. The mechanisms that require manual operation are all located at the edge of the frame for easy manual operation.

[0018] By employing the above technical solutions, this invention has the following advantages compared to existing technologies:

[0019] 1) The automatic labeling equipment for optical modules provided by this invention has a reasonable layout, high stability, and high labeling efficiency. It realizes automatic feeding and unloading of labeling materials through the loading and unloading mechanism, and drives the suction component to move through the conveying mechanism to realize the suction and pasting of labels, thereby improving the intelligence level of optical module labeling, reducing manual operation, and increasing production capacity and efficiency.

[0020] 2) The automatic labeling equipment for optical modules provided by the present invention can have its hopper assembly lowered below the frame under the drive of the hopper lifting mechanism. On the one hand, the hopper assembly can accommodate multiple layers of material trays containing optical modules, reducing the number of times the material boxes need to be replaced and saving manpower. On the other hand, the hopper assembly can be lowered below the frame, without occupying the running space of the machine, making the equipment layout compact and reasonable, the manual operation area small, and reducing the hidden footprint of the machine.

[0021] 3) The automatic labeling equipment for optical modules provided by this invention has a universal base plate for the material tray. By replacing different blister box supports, it can meet the needs of different models of optical modules, making the hopper components universal for all optical module blister boxes, thus having a wide range of applications.

[0022] 4) The automatic labeling device for optical modules provided by the present invention has a simple label peeling mechanism, is easy to operate, is equipped with a guide, and the label peeling separation plate is set close to the label separating port. The label peeling mechanism is not only suitable for conventional labels, but also for sheet labels, and has a wide range of applications.

[0023] 5) The automatic labeling equipment for optical modules provided by this invention performs bidirectional positioning of the picked-up labels and the incoming optical modules, resulting in higher labeling accuracy.

[0024] 6) The automatic labeling equipment for optical modules provided by the present invention allows the blister tray for placing the optical modules to be set on the base plate under the action of the internal support of the blister tray. During the process of the material tray moving to the labeling position, the flattening mechanism can help flatten the blister box, avoiding the risk of substandard labeling effect caused by the thin and soft deformation of the blister box material.

[0047] 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. In the accompanying drawings, the dimensions and relative dimensions of certain parts may be enlarged for clarity.

[0048] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connection" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] In the description of this invention, terms such as "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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.

[0050] Furthermore, in the description of this invention, the terms "first" and "second" are used merely for descriptive distinction and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Additionally, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0051] As per the instruction manual Figure 1 As shown, the present invention provides an automatic labeling device for optical modules, including a frame 1, and further including a loading and unloading mechanism 3, a label peeling mechanism 4, a material picking assembly 5, and a vision positioning mechanism 6 disposed on the frame 1. The loading and unloading mechanism 3 includes a drive mechanism 33 for driving the material tray 311 to switch between the loading / unloading position and the labeling position; the label peeling mechanism 4 is used to peel the label from the backing paper, and the label peeling mechanism 4 is connected to a label feeding mechanism 41 for supplying labels; the material picking assembly 5 includes a suction mechanism 52 capable of picking up and labeling, and a conveying mechanism 51 for driving the suction mechanism 52 to pick up the label from the label peeling mechanism 4 and to label at the labeling position.

[0052] Specifically, a platform 2 is fixed on the frame 1. The loading and unloading mechanism 3, the label peeling mechanism 4, the material picking assembly 5, and the vision positioning mechanism 6 are mounted on the platform 2. A lockable walking mechanism 11 is provided at the bottom of the frame 1 to facilitate the movement of the equipment. The walking mechanism 11 consists of rollers mounted at the bottom of the frame 1. A cover 12 is also provided on the platform 2. A viewing window 13 is provided on the front side of the cover 12 to facilitate observation of the labeling status inside the cover 12. Preferably, a control unit is also provided on the cover 12. The control unit includes a computer terminal for receiving and processing data. The vision positioning mechanism 6, the drive mechanism 33, the conveying mechanism 51, and the suction mechanism 52 are electrically connected to the control unit. A control panel for adjustment is also provided on the cover 12. The control panel has a switch and an adjustment knob.

[0053] In an optimized implementation, the loading and unloading mechanism 3 further includes a hopper assembly 31 and a hopper lifting mechanism 32. The hopper assembly 31 is provided with a plurality of material trays 311, and the material trays 311 are arranged sequentially from bottom to top. The hopper lifting mechanism 32 is connected to the hopper assembly 31 and is used to drive the hopper assembly 31 to lift and lower so that one of the material trays 311 moves to the loading and unloading position. Preferably, the loading and unloading position and the labeling position are arranged sequentially in the horizontal direction, so that the material tray 311 in the loading and unloading position can move between the loading and unloading position and the labeling position under the action of the driving mechanism 33.

[0054] Specifically, the drive mechanism 33 is a translation mechanism. The labeling position is within the movement stroke of the suction mechanism 52. After the suction mechanism 52 picks up the label with the peeled backing paper from the label peeling mechanism 4, it moves to the labeling position and pastes the label onto the optical module located at the labeling position. The optical module is placed in the material tray 311. The hopper layer of the hopper assembly 31, which is flush with the drive mechanism 33, is the loading and unloading position, which makes it easy for the drive mechanism 33 to move the material tray 311 out of or into the hopper assembly, thereby realizing automatic loading and unloading.

[0055] As one specific implementation method, the hopper lifting mechanism 32 can be set above the platform 2, and multiple material trays 311 are arranged in sequence along the vertical direction. The optical modules in the material trays 311 are labeled layer by layer by the hopper lifting mechanism 32 to realize the automatic loading and unloading of optical modules.

[0056] As one specific implementation method, as shown in the appendix to the instruction manual. Figure 2The diagram shows a hopper lifting mechanism. The platform 2 has clearance holes 21, allowing the hopper assembly 31 to pass through these holes and sink into the frame 1 without occupying space above the frame 1. The hopper lifting mechanism includes a transition seat 321, a hopper main board 322, a first lead screw motor 323, a first linear bearing 324, and a guide rod connecting plate 325. The transition seat 321 is mounted on the hopper main board 322 and installed at the bottom of the platform 2. Specifically, four transition seats 321 are evenly distributed on the hopper main board 322. The first linear bearing 324 includes a first linear bearing seat 324a and a guide rod 324b. The guide rod 324b passes through the linear bearing seat 324a, allowing them to slide relative to each other. The linear bearing seat 324a is fixed to the hopper main board 322 with screws. The upper end of the guide rod 324b is connected to... The guide rod connecting plate 325 is on which the hopper assembly 31 is mounted. To ensure the smooth movement of the guide rod connecting plate 325, four first linear bearings 324 are provided and evenly distributed on the guide rod connecting plate 325. The first lead screw motor 323 includes a lead screw 323a and a nut 323b. The nut 323b is sleeved on the lead screw 323a and the two can slide relative to each other. The nut 323b is fixed on the hopper main plate 322. The end of the lead screw 323a away from the motor is fixed to the guide rod connecting plate 325 through a lead screw bearing seat. Driven by the motor, the motor drives the lead screw 323a to rotate. The hopper main plate 322 remains stationary. The lead screw 323a drives the guide rod connecting plate 325 to move up and down. With the help of the relative sliding auxiliary guidance of the four sets of symmetrically and evenly distributed first linear bearings 324, the linear lifting and lowering movement of the hopper assembly 31 is finally realized.

[0057] Preferably, there are two ways to update the materials in the hopper. One way is that the hopper assembly 31 is mounted on the guide rod connecting plate 325. After all the optical modules in the hopper assembly 31 have been labeled, the hopper assembly 31 can be completely removed and replaced with a new hopper assembly 31 to repeat the labeling operation. The other way is to remove the material tray 311 in the hopper assembly 31 and replace it with the material tray 311 to be labeled, thus updating the hopper. This can be configured according to actual needs. Because multiple material trays 311 can be set in the hopper assembly 31, and each material tray... Multiple optical modules are installed inside the 311, and the material trays 311 are arranged layer by layer. When the hopper assembly 31 moves to the target position through the hopper lifting mechanism 32, the drive mechanism 33 aligns with one of the material trays 311 with labels, and the material tray 311 can be moved to the labeling position. After labeling is completed, the drive mechanism 33 sends the material tray 311 back into the hopper assembly 31. The hopper lifting mechanism 32 moves, driving the material trays 311 to be labeled to repeat the above operation until all the optical modules of the multiple material trays 311 of the hopper assembly 31 have completed the labeling operation.

[0058] Preferably, the guide rod connecting plate 325 is provided with a plurality of limiting pins 325a, which form a limiting frame that can accommodate the hopper assembly 31. The hopper assembly 31 can be placed manually within the limiting frame formed by the limiting pins 325a, which facilitates the picking and placing of the hopper assembly 31.

[0059] Preferably, in order to facilitate the control unit in recording the number of times the hopper lifting mechanism 32 rises or falls, during the labeling operation, the hopper lifting mechanism 32 rises or falls layer by layer, and the number of times it rises or falls is used to determine whether all the materials in the hopper assembly 31 have been labeled.

[0060] Of course, the hopper lifting mechanism 32 can also be a conventional linear motion mechanism such as a cylinder, hydraulic cylinder, or electric module, and can be set according to actual needs.

[0061] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 3-5 As shown, the hopper assembly 31 also includes a box body, with an opening on the side of the box body facing the drive mechanism 33 for the material tray 311 inside the box to enter and exit; preferably, the box body is assembled from a front plate 312, a rear plate 313, a side plate 314, a bottom plate 315, and a top plate 316. The front plate 312 and the rear plate 313 each have multiple layers of slide grooves 312a and 313a arranged sequentially from bottom to top on opposite sides, and the slide grooves 312a and 313a on the front plate 312 and the rear plate 313 are arranged one-to-one; the slide grooves... The grooves 312a and 313a are parallel to the direction of action of the drive mechanism 33. The material tray 311 is slidably disposed on the grooves 312a and 313a. The material tray 311 is inserted into the grooves 312a and 313a and then installed in the box. The grooves 312a and 313a are parallel to the direction of action of the drive mechanism 33, which facilitates the drive mechanism 33 to remove the material tray 311 from the box or to send the material tray 311 into the box. Preferably, the box can accommodate multiple material trays 311, thereby reducing the number of times the hopper needs to be manually updated and saving labor time.

[0062] Preferably, to facilitate the taking out of the box, a box handle 317 is also provided on the top plate of the box.

[0063] In an optimized implementation, the loading and unloading mechanism 3 further includes an identification unit for identifying the optical module. The identification unit is preferably a photoelectric sensor 34, which is positioned facing the hopper assembly 31. A photoelectric sensor window 312b is provided at the corresponding mounting position of the front panel 312 of the box. The photoelectric sensor window 312b faces the material tray 311 of each hopper layer. When the blister box 7 of each hopper layer moves to the loading and unloading position aligned with the drive mechanism 33, the photoelectric sensor 34 is aligned with the material tray 311 of that hopper layer through the photoelectric sensor window 312b. This is used to detect whether there is a material tray 311 inside the box and whether there is an optical module inside the material tray 311, thereby determining whether to perform subsequent automatic labeling work.

[0064] The hopper lifting mechanism 32 of this application is used to switch the alignment of material trays 311 of different hopper layers with the drive mechanism 33, thereby realizing the automatic loading and unloading function of material trays 311 of different hopper layers. The loading and unloading mechanism 3 can be lowered under the frame 1 through the clearance hole 21 on the platform 2, without occupying the running space of the machine platform, and without affecting the label transfer movement of the material picking assembly 5. The equipment layout is compact and reasonable, avoiding the risk of collision caused by abnormal operation of the conveying mechanism 51.

[0065] To optimize the implementation method and accommodate labeling of different optical module models, material tray 311 can be configured to be used with various optical module models; see the attached manual. Figure 5 As shown, the material tray 311 includes a base plate 311a and a blister box inner support 311b. The base plate 311a is a universal base plate, the width of which is adapted to the box body and can slide automatically within the slide grooves 312a and 313a. The blister box inner support 311b is installed on the base plate 311a by screws. By replacing the appropriate blister box inner support 311b, different optical module blister boxes 7 can be used. Since different optical module models have different shapes and sizes, the corresponding blister boxes 7 used to place the optical modules are also different. According to different types of blister boxes 7, matching blister box inner supports 311b are set to support and fix the thin and soft material blister boxes 7, so as to fix the blister boxes 7 on the material tray. The base plate 311a is universal, so as to allow the blister boxes 7 to slide freely within the box body. The material tray of the present invention is suitable for use with different models of optical modules such as 100G optical modules and 25G optical modules.

[0066] Preferably, the bottom plate 311a is provided with a gripper groove 311c on the side facing the drive mechanism 33. The drive mechanism 33 includes grippers, which are provided corresponding to the gripper groove 311c and are used to grip the material tray 311 and drive the material tray 311 to move.

[0067] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 6The diagram shows a schematic of the drive mechanism 33. The drive mechanism 33 also includes a symmetrically arranged box guide rail 331, a first cylinder 332, and a second cylinder 333. The first cylinder 332 is preferably a rodless cylinder. The second cylinder 333 is connected to the output end of the first cylinder 332. That is, when the telescopic rod of the first cylinder 332 extends or retracts, it can drive the second cylinder 333 to move. The gripper includes an upper gripper 334 and a lower gripper 335. The upper gripper 334 and the lower gripper 335 are arranged opposite to each other. The upper gripper 334 and the lower gripper 335 are mounted on the second cylinder and can move closer to each other to grip the material tray 311 or move further apart to release the material tray 311.

[0068] The material loading process of this application is as follows: when the designated bin layer is aligned with the mounting height of the symmetrically arranged box guide rails 331 under the drive of the bin lifting mechanism 32, the first cylinder 332 drives the second cylinder 333 to move towards the bin assembly 31. The positioning edge of the upper clamp 334 pushes the bottom plate 311a of the material tray 311 to the box side plate 314 of the bin assembly 31. Then, through the second cylinder 333, the lower clamp 335 hooks into the claw groove 311c of the bottom plate 311a, hooking the bottom plate 311a of the material tray. The first cylinder 332 then controls the second cylinder 333 to move in the opposite direction, moving away from the bin assembly 31 to the labeling position B. After labeling is completed, the unloading operation is performed. The unloading operation is the opposite of the loading operation. The first cylinder 332 drives the gripper to move towards the hopper assembly 31, sending the material tray 311 to the upper and lower material positions A and back into the box. Then, the next layer of hopper is replaced and the above operation is repeated to complete the labeling process until all the optical modules in the hopper assembly are labeled.

[0069] In an optimized implementation, the driving mechanism 33 is used to move the material tray 311 from the hopper assembly 31 to the labeling position B, or to send the labeled material tray 311 into the hopper assembly 31. Preferably, in order to ensure the labeling effect, a flattening mechanism 35 is provided between the upper / lower material position A and the labeling position B. The flattening mechanism 35 is located at the position through which the material tray 311 moves and is used to assist in flattening the blister box 7. The flattening mechanism 35 includes a suspended, liftable pressing roller 351 for applying pressure to the material tray 311 moving between the upper / lower material position and the labeling position. When the material tray 311 passes through the flattening mechanism 35, the pressing roller 351 can apply a certain pressure to the blister box 7, so that the blister box 7 can be tightly attached to the inner support 311b of the blister box, thereby ensuring that the product height in the blister box 7 at the labeling position is consistent and improving the labeling efficiency; when the labeling is completed, during the process of the material tray 311 returning to the hopper assembly 31, the pressing roller 351 can apply pressure to the label on the optical module, which can improve the adhesion reliability of the label on the optical module.

[0070] Preferably, the pressing roller 351 can be mounted on the platform 2 via a bracket. The pressing roller 351 is located above the material tray 311. Mounting seats 352 are provided at both ends of the pressing roller 351. The pressing roller 351 is rotatable. Multiple pressing rollers 351 can be set according to the size of the material tray 311 to meet the usage requirements of the material tray 311. In this embodiment, the pressing roller 351 is set on the conveying mechanism 51. The installation position and installation method of the flattening mechanism 35 can be set according to actual needs.

[0071] As one implementation method, see the appendix to the instruction manual. Figure 7 and 8 The diagram shows a flattening mechanism 35. The flattening mechanism 35 also includes a second linear bearing 353, a locking screw 354, and a compression spring 355. The second linear bearing 353 is mounted on a bracket or conveying mechanism 51. The locking screw 354 is disposed inside the second linear bearing 353. The second linear bearing 353 can serve as a guide and can restrict the vertical movement of the pressing roller 351. The threaded end of the locking screw 354 is connected to the mounting base 352. One end of the compression spring 355 abuts against the mounting base 352, and the other end abuts against the second linear bearing 353. The locking screw 354 passes through the compression spring 355. The locking screw 354 also includes a cap step 354a. Its working principle is as follows: under the elastic force of the compression spring 355 and the guiding action of the second linear bearing 353, the plug screw 354 applies downward force, thereby driving the pressing roller 351 fixed to the threaded end of the plug screw 354 to apply downward force. Due to the limiting action of the cap step 354a of the plug screw 354, the pressing roller 351 stops after descending to a fixed height. This fixed height is lower than the height of the blister box 7 on the drive mechanism 33. When the material tray 311 passes through the flattening mechanism 35, it is subjected to the pressure of the compression spring 355, which causes the pressing roller 351 to apply pressure, thereby making the thin and soft blister box 7 stick tightly to the inner support 311b of the blister box, thus ensuring that the height of the products to be labeled is consistent.

[0072] As one specific implementation method, as shown in the appendix to the instruction manual. Figure 11The diagram shows a label peeling mechanism 4, which includes a guide 43 for guiding the label paper and a label receiving assembly 45 for winding the backing paper, arranged sequentially along the label paper's running direction. One side of the guide 43 is provided with a label separating plate 432 for separating the label and the backing paper. The label peeling mechanism 4 is connected to a label feeding mechanism 41 for supplying label paper (including the backing paper and the label). The label peeling mechanism also includes a standing plate 46. Specifically, the label feeding mechanism 41 is used to fix the incoming label rolls, and the label receiving assembly 45 is used to wind the backing paper. The label separating plate 432 is arranged on the label paper's running path, and one side of the label separating plate 432 can abut against the backing paper. Dragging the backing paper across the label separating plate 432 causes the label to lift and separate from the backing paper.

[0073] In the optimized implementation, the label feeding mechanism 41 includes a label roll shaft 411 and first baffles 412 disposed on both sides of the label roll shaft 411. The first baffle 412 on the side closer to the upright plate 46 is fixed, while the first baffle 412 on the side farther from the upright plate 46 can move on the label roll shaft 411 and is adjustable according to the label width. The guide member 43 is used to restrict the movement of the label within a straight trajectory. The guide member 43 includes multiple guide rollers 431, and a label separating plate 432 is disposed between two adjacent guide rollers 431. A liftable rubber-coated bearing 433 is also disposed between the two guide rollers 431. Above the label separating plate 432; in this embodiment, there are two guide rollers 431, and the two guide rollers 431 are arranged in parallel. Second baffles 434 are provided at both ends of the guide rollers 431. The two guide rollers 431 share one side of the second baffle 434. The second baffle 434 on the side closer to the upright plate 46 is fixed, while the second baffle 434 on the side farther from the upright plate 46 can move along the guide rollers 431 and can be adjusted according to the label width. A rubber-coated bearing fixing seat 435 is also provided on the second baffle 434. The rubber-coated bearing 433 is mounted on the rubber-coated bearing fixing seat 435. The rubber-coated bearing fixing seat 435 can... The vertical adjustment is used to adjust the gap between the rubber-coated bearing 433 and the label separating plate 432. If the label width is smaller than the backing paper width, the rubber-coated bearing 433 is positioned at both ends of the label separating plate 432 to press down the backing paper, preventing wear on the label and allowing the backing paper to slide smoothly within the gap. Therefore, this structure is also suitable for sheet labels with a small order quantity. Specifically, the label separating plate 432 is tilted upwards on the side closest to the incoming material. The backing paper after passing through the label separating plate 432 changes direction via the rubber-coated bearing 433, facilitating the separation of the label and backing paper. A peeling plate 44 is provided on one side of the second guide roller 431 to peel the labels off one by one. A label separating opening is formed between the peeling plate 44 and the second guide roller 431. After passing through the second guide roller 431, the backing paper is wound onto the label receiving assembly 45 via the label separating opening. The label receiving assembly 45 is located below the guide member 43. The label receiving assembly 45 includes a label receiving motor 451, a label receiving shaft 452, and a shaft clamp 453. The label receiving motor 451 is located on the side of the upright plate 46 away from the label receiving shaft 452. The label receiving shaft 452 is connected to the output end of the label receiving motor 451. The shaft clamp 453 is located on the label receiving shaft 452. The label receiving shaft 452 and the shaft clamp 453 are used to hold the label backing paper, making it easier for the peeling plate 44 to peel the labels one by one.

[0074] In this optimized implementation, the peeling plate 44 is positioned close to the guide roller 431. After the label passes above the second guide roller 431, the backing paper passes through the label separating opening and is wound up by the take-up shaft 452. The peeling plate 44 is used to peel the label from the backing paper. The peeling plate 44 is mounted on the upright plate 46 via a fixed shaft 441. In this embodiment, the peeling plate 44 is inclined, and its inclination angle is set according to actual needs. A label receiving assembly 42 is provided on the side of the peeling plate 44 away from the guide roller 431. The label receiving assembly 42 includes a label receiving plate 421. The label receiving plate 421 is mounted on the upright plate 46 at one end. The label receiving plate 421 is used to receive the label peeled off by the label peeling plate 44. The fiber optic head 422 is fixedly mounted on the label receiving plate 421 and is used to sense the starting position of the label to ensure the consistency of the label length. The anti-sticking pad 423 is mounted on the label receiving plate 421. The peeled label moves to the anti-sticking pad 423 to ensure that the label has low stickiness and is easy to pick up when the suction nozzle 527 picks up the label. The anti-sticking pad is preferably an anti-sticking particle pad.

[0075] In an optimized implementation, to facilitate the suction nozzle 527 in picking up the label, the label receiving plate 421 is also provided with ventilation holes. The ventilation holes are set according to the label position. When necessary, air can be sucked into the label to ensure that the label is flat, or air can be blown into the label to reduce the difficulty of the suction nozzle in picking it up.

[0076] In an optimized implementation, the number of optical fiber heads 422 can be one or more to accommodate labels with different column numbers.

[0077] As one specific implementation method, as shown in the appendix to the instruction manual. Figure 12 The diagram shown is a schematic of another label-removing mechanism. The label-supplying mechanism 41, the upright plate 46, and the label-receiving component 45 in this embodiment have the same structure as the label-removing mechanism 4 in the above embodiment, so they will not be described again here.

[0078] Preferably, the guide member 43 includes a guide plate 436. In this embodiment, the guide plate 436 also serves as a label separating plate 432. One end of the guide plate 436 is connected to the upright plate 46. A mounting plate 436a is provided at the end of the guide plate 436 away from the upright plate 46. The mounting plate 436a extends out of the guide plate 436, and a peeling plate 44 is provided between its extended end and the upright plate 46. The peeling plate 44 also serves as a label receiving plate 421. The mounting plate 436a has a plurality of oblong holes, of which the vertical oblong holes are connected to the guide plate, and the horizontal oblong holes are connected to the peeling plate 44. A gap is provided between the peeling plate 44 and the guide plate 436 to form a label separating plate. The label-separating opening, through a waist-shaped hole, allows adjustment of the installation position of the label-splitting plate 44 and the guide plate 436, thereby adjusting the size of the label-separating opening to accommodate different label models. The label-splitting plate 44 is positioned close to the guide plate 436, and its height is lower than that of the guide plate 436. The label paper moves towards the label-separating opening via the guide plate 436, and the backing paper passes through the opening and is wound onto the label-receiving shaft 452. The upper end of the guide plate 436, near the label-splitting plate 44, abuts against the label paper for separating the label and the backing paper. The label-receiving assembly 45 is positioned below the guide plate 436. After the label paper passes through the guide plate 436, the label and the backing paper separate, and the separated label is peeled off onto the label-splitting plate 44, completing the label-splitting operation.

[0079] Preferably, a label pressing plate 437 is also provided above the guide plate 436, and a third cylinder 438 is also provided on the upright plate 46. The third cylinder 438 is connected to a lifting slide 439. The label pressing plate 437 is installed on the lifting slide 439. The label pressing plate 437 can move up and down under the drive of the third cylinder 438. When the label pressing plate 437 is away from the guide plate 436, it can be used for label roll replacement. When the label pressing plate 437 is close to the guide plate 436, it can press the label on the guide plate 436, which facilitates the subsequent label peeling operation.

[0080] Preferably, an elastic element is provided between the label pressing plate 437 and the lifting slide 439. The elastic element is preferably a spring. Under the action of the elastic element, the label pressing plate 437 can press down on the guide plate 436, thereby pressing the label down on the guide plate 436, which is convenient for peeling off the label. Preferably, the side of the label pressing plate 437 facing the guide plate 436 is provided with foam adhesive, which will not damage the label or scratch the label.

[0081] Preferably, the label stripping plate 44 in this embodiment can be used as a label receiving plate, and the labels separated by the guide plate 436 are sent to the label receiving plate; in this embodiment, the structure of the label receiving plate 421 is the same as that in the above embodiment, and it is provided with an optical fiber head and an anti-sticking pad, etc., so it will not be described again here.

[0082] Preferably, the height of the peeling plate 44 is adjustable, thereby adjusting the distance between it and the label-separating opening of the guide plate 436 to meet different label usage needs; at the same time, the pressure plate 437 is set close to the label-separating opening, which is not only suitable for label rolls, but also for sheet labels with a small number of work orders; it has a wide range of applications.

[0083] In an optimized implementation, the material handling assembly 5 includes a conveying mechanism 51 and a suction mechanism 52. The suction mechanism 52 is used to pick up the label from the label peeling mechanism 4 and correct the label angle. The label is then moved to the labeling position by the conveying mechanism 51 and affixed to the optical module. The conveying mechanism 51 is preferably a gantry conveying mechanism, which can move in the X and Y axes. The suction mechanism 52 is liftable, which can move the label in the X, Y and Z axes to complete the labeling operation.

[0084] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 9 As shown, the suction mechanism 52 includes a fixed plate 521, a suction nozzle lifting mechanism, a rotating mechanism, and a suction nozzle 527. The fixed plate 521 is mounted on the conveying mechanism 51. The suction nozzle lifting mechanism is located on the fixed plate 521. The rotating mechanism is located at the output end of the suction nozzle lifting mechanism. The suction nozzle 527 is located on the rotating mechanism. The suction nozzle 527 can adjust the label angle under the drive of the rotating mechanism to improve the labeling quality. The suction nozzle lifting mechanism can drive the rotating mechanism to move in the vertical direction to adjust the label position on the Z-axis, which is convenient for label picking and labeling.

[0085] Specifically, the nozzle lifting mechanism includes a second lead screw motor 522, a first slide rail 523, and a buffer slide 524. The second lead screw motor 522 and the first slide rail 523 are mounted on the fixed plate 521. The first slide rail 523 is vertically arranged. The buffer slide 524 is disposed on the first slide rail 523 and can move up and down along the first slide rail 523. The buffer slide 524 is connected to the output end of the second lead screw motor 522, and under the drive of the second lead screw motor 522, the buffer slide 524 moves up and down. A rotating mechanism is mounted on the buffer slide 524. The rotating mechanism includes a rotary motor 525 and a connector 526. The rotary motor 525 is mounted on the buffer slide 524. The rotary motor 525 is preferably a hollow motor. One end is connected to the suction nozzle 527 through the connector 526, and the other end is connected to a universal air pipe connector 528. The universal air pipe connector 528 is used to connect an external vacuum pump. The suction nozzle 527 can rotate at any angle θ under the drive of the rotary motor 525 as needed without twisting the air inlet pipe, thus meeting the labeling requirements.

[0086] In practical use, the suction nozzle 527 has various shapes and sizes. The suction nozzle 527 is threadedly connected to the connector 526, which allows for quick disassembly and replacement. The appropriate suction nozzle 527 can be selected according to specific usage requirements to meet the suction effect of labels of different sizes. In some embodiments, multiple suction nozzles 527 can be provided.

[0087] Preferably, the connector of the suction nozzle 527 can be rectangular. The suction nozzle 527 and the connecting piece 526 are oriented by the rectangular structure to ensure the consistency of the interchangeable angles of the suction nozzle 527. At the same time, the suction nozzle 527 structure is also provided with a limiting step to ensure the consistency of the Z-axis direction when replacing the suction nozzle 527 and to have a better airtight effect.

[0088] To optimize the implementation and prevent the nozzle 527 from impacting the optical module during labeling, the buffer slide 524 includes a first slider 524a and a second slider 524b. The first slider 524a is mounted on the first slide rail 524 and connected to the output end of the second lead screw motor 522. The rotary motor 525 is mounted on the second slider 524b. The second slider 524b is movably connected to the first slider 524a, and the two can slide relative to each other. An elastic element, preferably a spring, is built into the two. When the nozzle 527 descends to a height lower than the optical module, it can act as a buffer, ensuring the labeling effect without damaging the optical module.

[0089] In an optimized implementation, a limit stop plate 529 is also installed on the rotary motor 525, and a photoelectric switch 530 adapted to the limit stop plate 529 is installed on the buffer slide 524. A photoelectric sensing groove 529a is provided on the limit stop plate 529, which is used as the zero origin of the rotary motor 525.

[0090] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 10 As shown, the conveying mechanism 51 includes an X-axis linear module 511 and a Y-axis linear module 512. The X-axis linear module 511 is mounted on the Y-axis linear module 512. A fixed seat 513 is provided on the X-axis linear module 511. A fixed plate 521 of the suction assembly 52 is mounted on the fixed seat 513. The X-axis linear module 511 and the Y-axis linear module 512 can drive the fixed seat 513 to move in the X-axis and Y-axis directions, thereby realizing the movement of the suction nozzle 527 in the X-axis, Y-axis and Z-axis directions. The label peeling mechanism 4 is set within the stroke of the suction nozzle 527. The suction nozzle 527 can move between the label peeling station and the label pasting station for label suction and corrective pasting.

[0091] In an optimized implementation, the conveying mechanism 51 further includes a gantry bridge 514, which is positioned between the loading / unloading positions and the labeling position. The flattening mechanism 35 is installed at the bottom of the gantry bridge 514. The gantry bridge 514 is parallel to the Y-axis linear module 512 and is located at both ends of the X-axis linear module 511. A second slide rail 515 is also provided on the gantry bridge 514, which is positioned along the Y-axis. By providing the gantry bridge 514, it can be used to install the flattening mechanism 35 and to assist the Y-axis linear module 512 in balancing sliding and force application. Through motor drive control on the module, the suction mechanism 52 fixed on the X-axis linear module 511 can move in the X and Y axis directions.

[0092] In an optimized implementation, the visual positioning mechanism 6 includes a first identification mechanism 61 mounted on the frame 1 for identifying the label after it has been picked up, and a second identification mechanism 62 mounted on the transport mechanism 51 for identifying the optical module. Specifically, the first identification mechanism 61 is mounted on the frame, close to the label peeling mechanism 4, and facing upwards. When the picking mechanism 52 picks up the label, the first identification mechanism 61 collects the label information (including size, angle, etc.). The second identification mechanism 62 is mounted on the fixed seat 513 of the transport mechanism 51. The second identification mechanism collects the information of the optical module. Through two sets of visual positioning and position offset algorithms, the angle of the label can be corrected by the rotation mechanism 525 to ensure the consistency of the labeling position.

[0093] The first identification mechanism 61 and the second identification mechanism 62 have the same structure, and the description will focus on the structure of the first identification mechanism 61; as shown in the appendix to the specification. Figure 13 As shown, the first identification mechanism 61 includes an identification camera 611, a lens 612, a light source 613, and a structural component 614. The lens 612 and the camera 611 are fixed on the structural component 614. The depth of field of the lens 612 is compatible with the height difference of different light modules inside the blister box 7, satisfying the universality of the visual structure of different light modules. The light outlet of the first identification mechanism 62 is set upward.

[0094] In an optimized implementation, the first identification mechanism 61 and the second identification mechanism 62 are electrically connected to the control unit, enabling the acquisition of data collected by the first identification mechanism 61 and the second identification mechanism 62 for correcting the label angle. Preferably, when the material tray 311 moves to the labeling position, there is no obstruction above the material tray 311, and the second identification mechanism 62 can collect information about the optical module inside the material tray 311. When the second identification mechanism 62 detects problems such as the blister tray 7 being placed backwards or the optical module being placed backwards, it can issue an alarm to prompt manual repositioning of the optical module to correct the material feeding error.

[0095] In the optimized implementation, the hopper lifting mechanism 32 is located on one side of the frame 1, and the label peeling mechanism 4 is located on the other side of the frame 1, which facilitates manual updating of the hopper and replacement of the label rolls, making manual operation convenient.

[0096] Example 2

[0097] As per the instruction manual Figure 14 As shown, the present invention also provides an automatic labeling method for optical modules, comprising the following steps:

[0098] Material tray 311 is discharged from the warehouse, and drive mechanism 33 sends material tray 311 to the labeling position;

[0099] Specifically, the hopper assembly 31 is equipped with N layers of material trays 311 (N≥2). Each material tray 311 is equipped with multiple light modules through a blister box 7. First, it detects whether there is a blister box 7 in the hopper, ensuring that one of the material trays 311 is located at the upper or lower material position. If there is, the first cylinder 332 extends to the upper or lower material position, the second cylinder 333 extends to clamp the material tray 311, the first cylinder 332 retracts, and drives the material tray 311 to the labeling position. If no blister box 7 is detected in the hopper, it can be moved to the material layer with the blister box 7. During the movement of the hopper assembly driven by the hopper lifting mechanism 32, it is determined whether the number of rises or falls exceeds N-1 times. If so, the hopper assembly 31 needs to be replaced in time.

[0100] Label stripping mechanism 4 performs label removal operations;

[0101] Specifically, the label receiving shaft 452 rotates and determines whether the set time point has been exceeded. If so, a new label needs to be replaced; if not, the label starting point is detected, and the label receiving shaft 452 continues to rotate a fixed distance to complete the label peeling. Based on the label taking and labeling speed, continuous label peeling is achieved.

[0102] The suction mechanism 52 picks up the label from the label peeling mechanism 4 and moves it to the labeling position by the transport mechanism 51 for labeling.

[0103] Specifically, after the material tray 311 moves to the labeling position, the second identification mechanism 62 first moves to identify each optical module in the material tray. The current position coordinates of the modules are obtained through visual recognition, and the position coordinates of each optical module are marked as the first parameter. The position coordinates include the X-axis, Y-axis, and angle parameters. Then, the suction mechanism 52 picks up the label. When the XY linkage of the conveying mechanism 51 reaches the label picking position, the Z-axis of the suction nozzle 527 descends to the label picking height, and the suction nozzle 527 sucks air to complete the label picking. The Z-axis rises to the starting height, and the XY linkage is activated to the first identification mechanism 61 for label recognition. The first identification mechanism 61 identifies the position coordinates of the label on the suction nozzle 527 and records them as the second parameter. The position coordinates include the X-axis, Y-axis, and angle parameters. The angle compensation value is calculated by comparing the parameters of the label with the parameters of the optical module to be labeled. The software controls the nozzle 527 to rotate and calculate the angle compensation value so that the current label angle is consistent with the current optical module angle. After the label angle is corrected, the X-axis and Y-axis parameters of the label change. The first recognition mechanism 61 takes a second picture and recognizes the X-axis and Y-axis parameters of the label after the angle correction, which are recorded as the third parameter. The software then compensates and calibrates based on the first difference between the corrected label X-axis and Y-axis parameters (third parameter) and the optical module parameters (first parameter), and the second difference between the current X-axis and Y-axis parameters of the optical module obtained by moving the second recognition camera (fourth parameter) and the optical module parameters before label acquisition (first parameter).

[0104] The software calculates the current optical module position based on the second identification mechanism 62. If there is no optical module position to be labeled (all optical modules on the material tray have been labeled, and a new material tray can be replaced for labeling), and if there is a position to be labeled, the label picked up by the nozzle 527 is moved to the module identification position via XY linkage, the position coordinates of the label and the optical module are calibrated, the conveying mechanism 51 moves the picked-up label to the labeling position, the Z-axis descends to the labeling height, the nozzle 527 blows air to complete the labeling, and the Z-axis rises to the starting height to complete one labeling operation.

[0105] After labeling is completed, the drive mechanism 33 sends the material tray 311 to the upper and lower material positions.

[0106] Specifically, once all the optical modules in a material tray 311 have been labeled, the suction nozzle 527 returns to its starting position, the first cylinder 332 moves toward the hopper assembly 31 and pushes the material tray 311 into the box, the second cylinder 333 drives the gripper to release the material tray 311, and the first cylinder 332 retracts, thus achieving automatic feeding.

[0107] Those skilled in the art will understand that the present invention can be implemented in many other specific forms without departing from the spirit and scope of the invention. Although embodiments of the invention have been described, it should be understood that the invention is not limited to these embodiments, and those skilled in the art can make changes and modifications within the spirit and scope of the invention as defined in the appended claims.
