Description

Technical Field

[0001] This invention relates to the field of PCB technology, and in particular to a PCB labeling machine for optical modules. Background Technology

[0002] Printed circuit boards (PCBs), as the core carrier of electronic devices, are key components for achieving electrical connections between electronic components and are widely used in communications, consumer electronics, and industrial control. Optical module PCBs are printed circuit boards specifically adapted for optical modules, serving as the crucial carrier for photoelectric conversion and data transmission. Labeling optical module PCBs is a critical step in the manufacturing and subsequent management of optical modules. The information on the labels, such as model number, specifications, production batch, and unique identification code, enables full lifecycle traceability of the optical module PCB from production, inspection, warehousing to transportation and maintenance, facilitating production process control and quality issue localization for enterprises. In existing technologies, labeling machines are commonly used to label optical module PCBs. These machines typically include a conveying device and a labeling device. The conveying device holds a positioning fixture for positioning the optical module PCB. After the optical module PCB is fixed within the positioning fixture, the conveying device moves the positioning fixture to the labeling station. The labeling device then performs the labeling operation on the optical module PCB within the positioning fixture. During the labeling process, the transmission gap, running vibration, and track error of the conveying device are directly transmitted to the positioning fixture, causing slight displacement or shaking of the positioning fixture during labeling. Simultaneously, the labeling pressure applied by the labeling device further exacerbates the positioning fixture's offset, resulting in a shift or skew in the labeling position of the optical module PCB, which is detrimental to improving the labeling accuracy of the optical module PCB. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a labeling machine for optical module PCBs, which is beneficial to improving the labeling accuracy of optical module PCBs.

[0004] According to an embodiment of the present invention, a PCB labeling machine for optical modules includes a frame with a labeling station and a dwell station, the labeling station being positioned above the dwell station; a positioning fixture for positioning the optical module PCB; a conveying device mounted on the frame for conveying the positioning fixture to move it to the dwell station; a lifting device mounted on the frame for lifting the positioning fixture from the dwell station to the labeling station, thereby disengaging the positioning fixture from the conveying device; a clamping device mounted on the frame for clamping the positioning fixture at the labeling station; and a labeling device for affixing labels to the optical module PCB on the positioning fixture at the labeling station.

[0005] It has at least the following beneficial effects: First, the PCB of the optical module to be labeled is positioned and fixed in the positioning fixture. Then, the conveying device starts and transports the positioning fixture, allowing it to move precisely to the stopping position on the frame. Next, the lifting device starts to operate, lifting the positioning fixture at the stopping position upwards to the labeling station above the stopping position, so that the positioning fixture is completely detached from the conveying device. Then, the clamping device firmly clamps the positioning fixture at the labeling station. Finally, the labeling device starts and accurately affixes the label to the optical module PCB on the positioning fixture at the labeling station. After the labeling of the optical module PCB is completed, the clamping device first releases the positioning fixture, and the lifting device then lowers the positioning fixture from the labeling station back to the stopping position, so that the positioning fixture is placed back on the conveying device. The conveying device then transports the positioning fixture carrying the labeled optical module PCB to the next process. This optical module PCB labeling machine uses a lifting device to lift the positioning fixture to the labeling station and detach it from the conveying device. This effectively avoids the transmission gap and vibration of the conveying device being transmitted to the positioning fixture. At the same time, the clamping device's stable clamping of the positioning fixture can effectively resist the labeling pressure applied by the labeling device, preventing the positioning fixture from shifting or shaking during the labeling process. This avoids the labeling position of the optical module PCB from shifting or tilting, thus significantly improving the labeling accuracy of the optical module PCB.

[0006] According to an embodiment of the optical module PCB labeling machine of the present invention, the clamping device includes a first linear drive member, the first linear drive member is disposed on the frame, and the first linear drive member is capable of pressing the positioning fixture at the labeling station against the frame.

[0007] According to an embodiment of the optical module PCB labeling machine of the present invention, the clamping device further includes a flexible pusher and a flexible support. The flexible pusher is connected to the output end of the first linear drive, and the flexible support is disposed on the frame. The first linear drive can drive the flexible pusher to move toward the flexible support, so that the flexible pusher presses the positioning fixture at the labeling station against the flexible support.

[0008] According to an embodiment of the optical module PCB labeling machine of the present invention, the frame is provided with a first limiting member, and the lifting device is capable of pressing the positioning fixture against the first limiting member. The first limiting member is used to abut against the upper surface of the positioning fixture at the labeling station.

[0009] According to an embodiment of the optical module PCB labeling machine of the present invention, the lifting device includes a second linear drive and a support. The second linear drive is disposed on the frame, and the support is connected to the output end of the second linear drive. The second linear drive can drive the support to rise so that the support lifts the positioning fixture at the dwell station to the labeling station.

[0010] According to an embodiment of the optical module PCB labeling machine of the present invention, the lifting device further includes a second limiting member, the second limiting member being connected to the side of the support member opposite to the conveying direction of the conveying device, and the frame is further provided with a first station and a second station, the first station, the second station and the stopping station being distributed sequentially from bottom to top, the second linear drive member being able to drive the second limiting member to move to the second station, so that the second limiting member abuts against the positioning fixture and the positioning fixture stops at the stopping station, the second linear drive member being able to drive the second limiting member and the support member to move to the first station, so that the second limiting member and the support member simultaneously disengage from the positioning fixture.

[0011] According to an embodiment of the optical module PCB labeling machine of the present invention, the conveying device includes two belt conveying mechanisms, both of which are mounted on the frame, and the two belt conveying mechanisms are used to simultaneously support and convey the positioning fixture.

[0012] According to an embodiment of the optical module PCB labeling machine of the present invention, the conveying device further includes a first support and a second support, both of which are disposed on the frame. Two belt conveying mechanisms are respectively disposed on the first support and the second support. The first support is movable on the frame so that the distance between the first support and the second support can be adjusted.

[0013] According to an embodiment of the optical module PCB labeling machine of the present invention, the conveying device further includes a first lead screw, a second lead screw, and a clamping assembly. Both ends of the first lead screw and the second lead screw are rotatably connected to the frame. Both ends of the first support in the length direction are provided with threaded holes. The first lead screw and the second lead screw are respectively threadedly connected to the two threaded holes. One end of the first lead screw is provided with an adjusting handwheel. The other ends of the first lead screw and the second lead screw are drively connected. The adjusting handwheel can simultaneously drive the first lead screw and the second lead screw to rotate, so that the first lead screw and the second lead screw drive the first support to move closer to or away from the second support. The clamping assembly is provided on the frame and is used to clamp the first lead screw and the second lead screw to restrict the rotation of the first lead screw and the second lead screw.

[0014] According to an embodiment of the present invention, a labeling machine for optical module PCBs includes a label peeling mechanism, a three-axis drive mechanism, an image recognition mechanism, and an adsorption mechanism. The three-axis drive mechanism and the label peeling mechanism are both mounted on the frame. The label peeling mechanism is used to peel labels from a label strip. The output end of the three-axis drive mechanism is connected to the image recognition mechanism and the adsorption mechanism. The image recognition mechanism is used to identify the labeling position on the optical module PCB at the labeling station. The adsorption mechanism is used to adsorb or release labels. The three-axis drive mechanism is used to drive the image recognition mechanism and the adsorption mechanism to move in the up-down, left-right, and front-back directions.

[0018] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0019] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0020] refer to Figure 1 and Figure 2 This invention discloses a labeling machine for optical module PCBs, comprising a frame 500, a positioning fixture, a conveying device 100, a lifting device 200, a clamping device 300, and a labeling device 400. The frame 500 has a labeling station and a stopping station, with the labeling station positioned above the stopping station. The positioning fixture is used to position the optical module PCB. The conveying device 100 is mounted on the frame 500 and is used to convey the positioning fixture so that it can move to the stopping station. The lifting device 200 is mounted on the frame 500 and is used to lift the positioning fixture from the stopping station to the labeling station, so that the positioning fixture is detached from the conveying device 100. The clamping device 300 is mounted on the frame 500 and is used to clamp the positioning fixture at the labeling station. The labeling device 400 is used to affix labels to the optical module PCB on the positioning fixture at the labeling station.

[0021] Understandably, the process involves first positioning and fixing the PCB of the optical module to be labeled within the positioning fixture. Then, the conveyor 100 is activated and transports the positioning fixture, precisely moving it to the stopping position of the frame 500. Next, the lifting device 200 operates, lifting the positioning fixture at the stopping position upwards to the labeling station above the stopping position, completely detaching the positioning fixture from the conveyor 100. Subsequently, the clamping device 300 securely clamps the positioning fixture at the labeling station. Finally, the labeling device 400 is activated, accurately affixing the label to the optical module PCB on the positioning fixture at the labeling station. After labeling the optical module PCB, the clamping device 300 first releases the positioning fixture, and the lifting device 200 lowers the positioning fixture from the labeling station back to the stopping position, placing it back on the conveyor 100. The conveyor 100 then transports the positioning fixture carrying the labeled optical module PCB to the next process. The optical module PCB labeling machine uses a lifting device 200 to lift the positioning fixture to the labeling station and detach the positioning fixture from the conveying device 100. This effectively prevents the transmission gap and running vibration of the conveying device 100 from being transmitted to the positioning fixture. At the same time, the clamping device 300's stable clamping of the positioning fixture can effectively resist the labeling pressure applied by the labeling device 400, preventing the positioning fixture from shifting or shaking during the labeling process. This avoids the labeling position of the optical module PCB from shifting or tilting, thereby significantly improving the labeling accuracy of the optical module PCB.

[0022] refer to Figures 5 to 7 The clamping device 300 includes a first linear drive 310, which is mounted on the frame 500 and located on one side of the labeling station. The first linear drive 310 can press the positioning fixture at the labeling station against the frame 500. Understandably, after the positioning fixture is lifted to the labeling station by the lifting device 200 and completely detached from the conveying device 100, the first linear drive 310, located on the frame 500 and on one side of the labeling station, is activated. The output end of the first linear drive 310 extends towards the positioning fixture and applies a clamping force, firmly clamping the positioning fixture onto the frame 500 to complete the clamping and fixing of the positioning fixture. Subsequently, the labeling device 400 is activated, and the labeling device 400 accurately affixes the label to the preset position of the optical module PCB on the positioning fixture. After the labeling of the optical module PCB is completed, the output end of the first linear drive 310 retracts and resets, releasing the clamping effect on the positioning fixture. Then, the lifting device 200 drives the positioning fixture to descend from the labeling station back to the dwell station and place it back on the conveying device 100. Finally, the conveying device 100 transports the positioning fixture carrying the labeled optical module PCB to the next process.

[0023] refer to Figures 5 to 7The clamping device 300 also includes a flexible pusher 320 and a flexible support 330. The flexible pusher 320 is connected to the output end of the first linear drive 310. The flexible support 330 is mounted on the frame 500. The first linear drive 310 can drive the flexible pusher 320 to move toward the flexible support 330 so that the flexible pusher 320 presses the positioning fixture at the labeling station onto the flexible support 330. Understandably, after the positioning fixture is lifted to the labeling station by the lifting device 200 and detached from the conveying device 100, the first linear drive 310 is activated. Since the flexible pusher 320 is connected to the output end of the first linear drive 310, the first linear drive 310 will drive the flexible pusher 320 to move towards the flexible support 330 mounted on the frame 500. During the movement, the flexible pusher 320 abuts against the positioning fixture. As the first linear drive 310 continues to apply force, the flexible pusher 320 steadily pushes the positioning fixture towards the flexible support 330 until the positioning fixture is tightly pressed against the flexible support 330, thus achieving... The flexible pusher 320 and flexible support 330 securely clamp the positioning fixture; then the labeling device 400 starts and accurately pastes the label onto the preset position of the optical module PCB on the positioning fixture; after the labeling of the optical module PCB is completed, the first linear drive 310 drives the flexible pusher 320 away from the flexible support 330, so that the flexible pusher 320 resets and releases the clamping force on the positioning fixture. The lifting device 200 then drives the positioning fixture down from the labeling station back to the dwell station and puts it back on the conveying device 100. Finally, the conveying device 100 transports the positioning fixture carrying the labeled optical module PCB to the next process. The flexible pusher 320 and the flexible support 330 can effectively buffer the impact force during the clamping process and prevent the positioning fixture from being squeezed and damaged due to rigid contact. On the other hand, the flexible pusher 320 can better fit the surface of the positioning fixture, increase the contact area to improve clamping stability, and form a bidirectional limit with the flexible support 330, which can more reliably resist the labeling pressure and further reduce the displacement or shaking of the positioning fixture.

[0024] In this embodiment of the invention, the flexible pusher 320 and the flexible support 330 are both common rubber blocks, the first linear drive 310 is a first cylinder, the cylinder body of the first cylinder is connected to the frame 500, and the piston rod of the first cylinder is connected to the flexible pusher 320, which will not be described further here.

[0025] refer to Figures 5 to 7The frame 500 is equipped with a first limiting member 510. The lifting device 200 can press the positioning fixture against the first limiting member 510. The first limiting member 510 is used to abut against the upper surface of the positioning fixture at the labeling station. It can be understood that after the positioning fixture is conveyed to the stopping station by the conveying device 100, the conveying device 100 stops operating, and the lifting device 200 immediately starts and lifts the positioning fixture upwards, causing the positioning fixture to detach from the conveying device 100 and move towards the labeling station. When the positioning fixture rises to the preset height of the labeling station, the upper surface of the positioning fixture abuts against the lower surface of the first limiting member 510. The lifting device 200 continuously applies an upward lifting force, firmly pressing the positioning fixture against the lower surface of the first limiting member 510, completing the vertical limiting and fixing of the positioning fixture. Subsequently, the first linear drive member 310 drives the flexible... The pusher 320 moves toward the flexible support 330, causing the flexible pusher 320 and the flexible support 330 to clamp the positioning fixture; the labeling device 400 starts and accurately pastes the label onto the optical module PCB. After the labeling is completed, the first linear drive 310 drives the flexible pusher 320 to reset to release the clamping force. The lifting device 200 retracts downward to disengage the positioning fixture from the contact state with the first limit member 510, and smoothly lowers the positioning fixture back to the stopping position and places it on the conveying device 100. Finally, the conveying device 100 transports the positioning fixture carrying the labeled optical module PCB to the next process. The lifting device 200 actively presses the positioning fixture against the lower surface of the first limiting member 510, forming a vertical limit on the positioning fixture. This effectively prevents upward displacement or sinking of the positioning fixture due to labeling pressure or fluctuations of the lifting device 200 during the labeling process. The first limiting member 510, in conjunction with the flexible pushing member 320 and the flexible support member 330, provides horizontal clamping, thus providing dual vertical and horizontal limiting for the positioning fixture. This ensures that the positioning fixture will not shift or shake during the labeling process, thereby improving the labeling accuracy of the optical module PCB. In this embodiment of the invention, the first limiting member 510 is connected to the flexible support member 330.

[0026] refer to Figures 5 to 7The lifting device 200 includes a second linear drive 210 and a support 220. The second linear drive 210 is mounted on the frame 500. The support 220 is connected to the output end of the second linear drive 210. The second linear drive 210 can drive the support 220 to rise so that the support 220 lifts the positioning fixture at the station to the labeling station. Understandably, after the conveyor 100 transports the positioning fixture carrying the optical module PCB to the stopping station, the conveyor 100 stops operating to maintain the stability of the positioning fixture's position. Subsequently, the second linear drive 210 starts operating. Since the support 220 is connected to the output end of the second linear drive 210, the second linear drive 210 drives the support 220 to move upward. After the support 220 rises to abut against the bottom of the positioning fixture at the stopping station, the second linear drive 210 continues to drive the support 220 upward, causing the support 220 to support the positioning fixture and drive the positioning fixture upward. When the positioning fixture is lifted by the support 220 to the preset position of the labeling station, the second linear drive 210 stops operating. In the first step, the support member 220 maintains its supporting position on the positioning fixture. Then, the clamping device 300 firmly clamps the positioning fixture at the labeling station. After clamping the positioning fixture, the labeling device 400 starts and accurately affixes the label to the optical module PCB surface on the positioning fixture. After labeling the optical module PCB, the clamping device 300 first releases the clamp on the positioning fixture, and then the second linear drive member 210 drives the support member 220 to slowly descend with the positioning fixture until it is placed back on the conveying device 100. After the positioning fixture stabilizes, the support member 220 continues to descend and reset. Finally, the conveying device 100 starts, transporting the positioning fixture carrying the labeled optical module PCB to the next production process. In this embodiment, the second linear drive member 210 is a second cylinder, the cylinder body of which is connected to the frame 500, and the piston rod of which is connected to the support member 220.

[0027] refer to Figures 5 to 7 The lifting device 200 also includes a second limiting member 230, which is connected to the side of the support member 220 away from the conveying direction of the conveying device 100. The frame 500 is also provided with a first station and a second station, which are arranged sequentially from bottom to top. The second linear drive member 210 can drive the second limiting member 230 to move to the second station so that the second limiting member 230 abuts against the positioning fixture and the positioning fixture stops at the stopping station. The second linear drive member 210 can drive the second limiting member 230 and the support member 220 to move to the first station so that the second limiting member 230 and the support member 220 simultaneously disengage from the positioning fixture.

[0028] Understandably, as the positioning fixture approaches the stopping station, the second limiting member 230, driven by the second linear drive member 210, has moved to the second station and remains stable. Subsequently, the conveying device 100 transports the positioning fixture carrying the optical module PCB to the stopping station. When the positioning fixture abuts against the second limiting member 230 at the second station, the conveying device 100 stops, and the positioning fixture precisely stops at the stopping station under the blocking limit of the second limiting member 230. Then, the second linear drive member 210 starts, driving the support member 220 upwards. The support member 220 rises until it abuts against the bottom of the positioning fixture and continues to apply force, causing the positioning fixture to rise synchronously. During this process, the second limiting member 230 moves with the support member 220 and remains abutted against the positioning fixture until the positioning fixture is lifted to the preset position of the labeling station, at which point the second linear drive member 210 stops. Afterwards, the clamping device 300 applies the label. The positioning fixture at the workstation firmly clamps the PCB, and the labeling device 400 starts and completes the labeling operation. After labeling, the clamping device 300 first releases the clamp, and the second linear drive 210 then drives the support 220 and the second limiting member 230 to move downwards synchronously. When the second limiting member 230 moves with the support 220 below the second workstation, the contact between the second limiting member 230 and the positioning fixture is released. When the second limiting member 230 and the support 220 continue to descend to the first workstation, the support 220 also completely disengages from the positioning fixture. At this time, the second limiting member 230 and the support 220 are both located below the positioning fixture. The positioning fixture smoothly falls back to the stopping position and is placed on the conveying device 100. Finally, the conveying device 100 starts and transports the positioning fixture carrying the labeled optical module PCB to the next process. At the same time, the second linear drive 210 drives the second limiting member 230 to rise to the second workstation to prepare for the next operation.

[0029] As the positioning fixture approaches, the second limiting member 230 stops at the second station. The second limiting member 230, through physical contact, replaces the braking positioning solely reliant on the conveyor device 100, effectively compensating for the feeding error of the conveyor device 100. This ensures that the positioning fixture can accurately stop at the stopping station each time, ensuring that the subsequent positioning fixture can be accurately lifted to the labeling station. During the process of the support member 220 lifting the positioning fixture, the second limiting member 230 moves synchronously with the support member 220 and maintains contact with the positioning fixture. The second limiting member 230 can correct any lateral deviation that may occur during the lifting process, ensuring that the positioning fixture rises smoothly vertically to the labeling station. After labeling the optical module PCB is completed, the second linear drive member 210 simultaneously drives the second limiting member 230 and the support member 220 to descend to the first station. This not only allows the positioning fixture to smoothly fall back onto the conveyor device 100, but also avoids interference between the second limiting member 230 and the support member 220 and the movement of the positioning fixture. In this embodiment of the invention, a photoelectric sensor is provided on the frame 500. The photoelectric sensor is used to detect whether there is a positioning fixture at the stopping station. It is understood that when the photoelectric sensor detects that the positioning fixture has moved to the stopping station, the photoelectric sensor sends a signal to the conveying device 100, and the conveying device 100 stops conveying, so that the positioning fixture accurately stops at the stopping station. The photoelectric sensor is a common type of positioning sensor; the cooperation process between the photoelectric sensor and the conveying device 100 will not be further described here.

[0030] refer to Figure 5 and Figure 7 The conveying device 100 includes two belt conveyor mechanisms 130, both of which are mounted on the frame 500. The two belt conveyor mechanisms 130 are used to simultaneously support and convey the positioning fixture. Understandably, after fixing the PCB of the optical module to be labeled onto the positioning fixture, the operator or the loading robot places the positioning fixture on two belt conveyor mechanisms 130. The two belt conveyor mechanisms 130 start synchronously and maintain the same speed, jointly supporting the positioning fixture and driving it smoothly to the stopping station. When the positioning fixture reaches the stopping station, the two belt conveyor mechanisms 130 stop running synchronously. Then, the lifting device 200 lifts the positioning fixture to the labeling station and disengages the positioning fixture from the two belt conveyor mechanisms 130. The clamping device 300 firmly clamps the positioning fixture, and after the labeling device 400 completes the labeling of the optical module PCB, the clamping device 300 releases the positioning fixture. The lifting device 200 sends the positioning fixture back to the stopping station and places it back on the two belt conveyor mechanisms 130. The two belt conveyor mechanisms 130 start synchronously again, transporting the positioning fixture carrying the labeled optical module PCB to the next process.

[0031] refer to Figure 5 and Figure 7The conveying device 100 also includes a first support 110 and a second support 120, both of which are mounted on the frame 500. Two belt conveyor mechanisms 130 are respectively mounted on the first support 110 and the second support 120. The first support 110 is movable on the frame 500 to adjust the distance between the first support 110 and the second support 120. It is understood that the first support 110's movable position on the frame 500 allows for adjustment of the distance between the first support 110 and the second support 120, thereby enabling adjustment of the distance between the two belt conveyor mechanisms 130. Optical module PCBs of different widths typically correspond to positioning fixtures of different widths. Operators can change the relative positions of the two belt conveyor mechanisms 130 by moving the first support 110, ensuring that the two belt conveyor mechanisms 130 always provide symmetrical and stable support for positioning fixtures of different widths. This allows the two belt conveyor mechanisms 130 to meet the labeling requirements of various specifications of positioning fixtures and optical module PCBs, significantly improving the versatility and adaptability of the optical module PCB labeling machine. In this embodiment of the invention, the first support 110 is slidably connected to the frame 500 via a slide rail slider, allowing the first support 110 to move linearly closer to or further away from the second support 120.

[0032] In this embodiment of the invention, the first linear drive member 310 is disposed on the first support 110, the flexible push member 320 is connected to the output end of the first linear drive member 310, the flexible support member 330 is disposed on the second support 120, and the first limiting member 510 is disposed on the flexible support member 330.

[0033] refer to Figure 5 and Figure 7The conveying device 100 also includes a first lead screw 140, a second lead screw 150, and a clamping assembly 160. Both ends of the first lead screw 140 and the second lead screw 150 are rotatably connected to the frame 500. Both ends of the first support 110 in the length direction are provided with threaded holes. The first lead screw 140 and the second lead screw 150 are respectively threaded to the two threaded holes. One end of the first lead screw 140 is provided with an adjusting handwheel 141. The other ends of the first lead screw 140 and the second lead screw 150 are drive-connected. The adjusting handwheel 141 can drive the first lead screw 140 and the second lead screw 150 to rotate simultaneously, so that the first lead screw 140 and the second lead screw 150 drive the first support 110 to move closer to or away from the second support 120. The clamping assembly 160 is provided on the frame 500 and is used to clamp the first lead screw 140 and the second lead screw 150 to limit the rotation of the first lead screw 140 and the second lead screw 150. Understandably, when it is necessary to adjust the distance between the two belt conveyor mechanisms 130 according to the size of the positioning fixture, the operator first operates the clamping assembly 160 on the frame 500 to release the clamping assembly 160 from the clamping and fixing of the first lead screw 140 and the second lead screw 150, allowing the first lead screw 140 and the second lead screw 150 to rotate; then, the operator rotates the adjusting handwheel 141 located at one end of the first lead screw 140. Since the other end of the first lead screw 140 and the second lead screw 150 are connected by a transmission, the adjusting handwheel 141 will synchronously drive the first lead screw 140 and the second lead screw 150 to rotate; because the threaded holes at both ends of the first support 110 are threadedly engaged with the first lead screw 140 and the second lead screw 150 respectively, When the first lead screw 140 and the second lead screw 150 rotate, they drive the first support 110 to move along the length direction of the first lead screw 140 and the second lead screw 150 through threaded transmission, thereby adjusting the position of the first support 110 closer to or further away from the second support 120. When the first support 110 moves to the target position and the distance between the two belt conveyor mechanisms 130 is adapted to the size of the positioning fixture, the operator stops rotating the adjusting handwheel 141 and operates the clamping assembly 160 again, so that the clamping assembly 160 forms a stable clamp on the first lead screw 140 and the second lead screw 150, restricting the rotation of the first lead screw 140 and the second lead screw 150 to fix the position of the first support 110, thus completing the distance adjustment of the two belt conveyor mechanisms 130.

[0034] In this embodiment of the invention, the other ends of the first lead screw 140 and the second lead screw 150 are connected by a pulley belt. The belt conveyor mechanism 130 is a common material conveying mechanism. The clamping assembly 160 includes a common first clamp and a second clamp. The first clamp and the second clamp are used to clamp the first lead screw 140 and the second lead screw 150, respectively. Further details will not be provided here.

[0035] refer to Figures 2 to 4The labeling device 400 includes a label peeling mechanism 410, a three-axis drive mechanism 420, an image recognition mechanism 430, and an adsorption mechanism 440. The three-axis drive mechanism 420 and the label peeling mechanism 410 are both mounted on the frame 500. The label peeling mechanism 410 is used to peel the label from the label strip. The output end of the three-axis drive mechanism 420 is connected to the image recognition mechanism 430 and the adsorption mechanism 440. The image recognition mechanism 430 is used to identify the labeling position on the optical module PCB at the labeling station. The adsorption mechanism 440 is used to adsorb or release the label. The three-axis drive mechanism 420 is used to drive the image recognition mechanism 430 and the adsorption mechanism 440 to move in the up-down, left-right, and front-back directions.

[0036] Understandably, the PCB of the optical module to be labeled is first positioned and fixed in the positioning fixture. Then, the conveying device 100 is started, moving the positioning fixture towards the stopping station. When the positioning fixture accurately reaches the stopping station, the conveying device 100 stops. Simultaneously, the label peeling mechanism 410 peels the label from the label strip, and the three-axis drive mechanism 420 drives the adsorption mechanism 440 to move to the label peeling mechanism 410, so that the adsorption mechanism 440 adsorbs the peeled label from the label peeling mechanism 410. After the positioning fixture moves to the stopping station, the lifting device 200 is activated, lifting the positioning fixture at the stopping station to the labeling station above the stopping station. During this process, the positioning fixture is completely detached from the conveying device 100, and the clamping device 300 then firmly clamps the positioning fixture at the labeling station, completing the positioning preparation before labeling. At the same time, the three-axis drive mechanism 420 drives the adsorption mechanism 440 to move to the label peeling mechanism 410, so that the adsorption mechanism 440 adsorbs the peeled label. The moving mechanism 420 drives the image recognition mechanism 430 and the adsorption mechanism 440 to move above the positioning fixture at the labeling station. The image recognition mechanism 430 takes a picture of the optical module PCB on the positioning fixture at the labeling station and performs image recognition to identify the labeling position on the optical module PCB. Then, the image recognition mechanism 430 sends the position information to the three-axis drive mechanism 420. The three-axis drive mechanism 420 drives the adsorption mechanism 440 to move above the labeling position on the optical module PCB. Then, the three-axis drive mechanism 420 drives the adsorption mechanism 440 to descend, so that the label adsorbed by the adsorption mechanism 440 is pasted to the pasting position on the optical module PCB. The adsorption mechanism 440 releases the label, and the label peeling mechanism 410 peels the next label from the label strip. The three-axis drive mechanism 420 drives the adsorption mechanism 440 to move to the label peeling mechanism 410 so that the adsorption mechanism 440 can adsorb the next label. After labeling the optical module PCB, the clamping device 300 first releases the positioning fixture, and the lifting device 200 then lowers the positioning fixture from the labeling station back to the dwell station, so that the positioning fixture is placed back on the conveying device 100. The conveying device 100 then conveys the positioning fixture carrying the labeled optical module PCB to the next process.

[0037] In this embodiment of the invention, the label peeling mechanism 410, the three-axis drive mechanism 420, the image recognition mechanism 430, and the adsorption mechanism 440 are all common configurations in the PCB labeling field, and will not be described in further detail here.
