Description

Technical Field

[0001] This utility model relates to the field of optical module insertion and removal technology, and in particular to an optical module insertion and removal device. Background Technology

[0002] In the production of optical modules, the process of inserting optical modules (usually referring to components with optical interfaces or internal optical elements) onto a PCB board for baking and soldering is a process designed to meet the special requirements of optical modules in terms of "precision", "thermal sensitivity" and "multi-material compatibility". The core purpose is to ensure soldering quality, avoid component damage, and ensure accurate matching between the optical path and the circuit.

[0003] Currently, optical module insertion and removal mainly rely on manual methods. The optical modules are inserted into the PCB board and then removed from the PCB board after baking and soldering. Since the insertion and removal process depends on manual operation, the manual handling results in slow insertion and removal speed, which is difficult to meet the needs of large-scale production. Furthermore, the alignment of the optical module and the PCB depends on manual visual inspection or simple clamps, which is prone to misalignment and affects the soldering quality. When there are many optical modules and their size is small, manual operation is prone to fatigue. Combined with factors such as skill level, this will further lead to fluctuations in product yield. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem in the prior art that when there are many optical modules and they are small in size, manual operation is prone to fatigue, and combined with the influence of skill level and other factors, it will further lead to fluctuations in product yield. Thus, an optical module insertion and removal device is provided.

[0005] To solve the above-mentioned technical problems, this utility model provides an optical module plugging and unplugging device, comprising:

[0006] Support platform;

[0007] The positioning mechanism includes a first positioning component and a second positioning component disposed on a support platform. The first positioning component is used to lock the circuit board to be inserted or removed and is provided with an insertion / removal station. The first positioning component includes at least a first positioning unit and a second positioning unit disposed opposite to each other. The second positioning component is used to place an optical module.

[0008] A feeding mechanism is disposed on one side of the first positioning component on the support platform and is at least used to move the circuit board to be inserted or removed from the input end of the first positioning component to the insertion / removal station or to remove the inserted circuit board from the insertion / removal station.

[0009] The insertion and removal mechanism is located on the support platform and is used to move and insert / remove the optical module between the second positioning component and the insertion / removal station, respectively.

[0010] In one embodiment of the present invention, the first positioning unit includes: a support extending along a first direction, a first driving member disposed on the support, and a pressing member connected to the output end of the first driving member and capable of pressing against the circuit board to be inserted or removed.

[0011] In one embodiment of the present invention, a plug-in platform is provided on a support platform. The plug-in platform is provided with a guide component. The second positioning unit is movably connected to the plug-in platform through the guide component to move closer to or further away from the first positioning unit.

[0012] In one embodiment of the present invention, a locking component is detachably connected between the second positioning unit and the insertion / removal platform. The locking component includes: a first locking seat and a second locking seat respectively connected to the insertion / removal platform and the second positioning unit, and a fixing member connected to the first locking seat and the second locking seat. The first locking seat is provided with a plurality of positioning holes adapted to the fixing member along its length direction.

[0013] In one embodiment of the present invention, a fourth linear drive member is further provided on the support platform. The fourth linear drive member is arranged along the second direction, and the plug-in platform is connected to the output end of the fourth linear drive member.

[0014] In one embodiment of the present invention, a detection mechanism is further provided on one side of the first positioning component. The detection mechanism is used to identify and detect the circuit board to be inserted or removed. The detection mechanism includes: a first linear drive member disposed on one side of the first positioning component and used to drive along a first direction, and a detection unit connected to the output end of the first linear drive member and having its detection end facing the insertion / removal station.

[0015] In one embodiment of the present invention, the feeding mechanism includes: a third linear drive member disposed on one side of the first positioning component and capable of being driven along a first direction, and a first clamping component connected to the output end of the third linear drive member, wherein the first clamping component is used to clamp the circuit board to be inserted or removed and transfer it to the insertion / removal station.

[0016] In one embodiment of the present invention, the second positioning component includes: a positioning support disposed on one side of the first positioning component, and a first adsorption member installed on the positioning support, wherein the first adsorption member is used to accommodate the optical module.

[0017] In one embodiment of the present invention, the optical module plugging and unplugging device further includes a buffer mechanism, the buffer mechanism including: a buffer support disposed on one side of the first positioning component, and a second adsorption member connected to the end of the buffer support.

[0018] In one embodiment of the present invention, the insertion and removal mechanism includes: a robotic arm disposed on one side of the positioning mechanism, a second clamping component connected to the output end of the robotic arm, and an identification unit disposed on one side of the second clamping component.

[0019] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0020] The optical module insertion / removal device of this utility model supports and positions the circuit board through a first positioning unit and a second positioning unit. A feeding mechanism delivers the circuit board to the insertion / removal station, where the first and second positioning units lock the circuit board in place, preventing displacement during insertion / removal. The device, in conjunction with the insertion / removal mechanism, picks up the optical module from the second positioning component and inserts it into the circuit board at the insertion / removal station, or removes the optical module from the circuit board and places it onto the second positioning component. The positioning and insertion / removal processes do not require direct manual contact with the optical module, avoiding damage caused by manual operation and eliminating deviations due to inaccurate positioning during manual operation. This minimizes the insertion error of the optical module and significantly improves product quality stability. Attached Figure Description

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0038] Example

[0039] In this embodiment, for ease of understanding, Figure 1 Based on the reference, the X-axis direction is the first direction, the Y-axis direction is the second direction, the first and second directions are horizontal, and the Z-axis direction is the height direction.

[0040] Reference Figures 1-4 As shown, the optical module insertion and removal device of this utility model includes: a support platform 13, a positioning mechanism, an insertion and removal mechanism 2, and a feeding mechanism 3. Further, the optical module insertion and removal device also includes a buffer mechanism 10.

[0041] The support platform 13 is equipped with a positioning mechanism, a feeding mechanism 3, a buffer mechanism 10, and a plug-in mechanism 2. The support platform 13 provides the installation foundation and working space for the positioning mechanism, the feeding mechanism 3, the buffer mechanism 10, and the plug-in mechanism 2, so that each actuator maintains relative positional accuracy during operation, avoids assembly errors caused by foundation deformation or unreasonable layout, and at the same time, optimizes the layout to ensure that the movement trajectories of each mechanism do not interfere with each other, thereby improving work efficiency.

[0042] Reference Figure 1 As shown, the positioning mechanism includes a first positioning component 1 and a second positioning component 5. For inserting and removing optical modules from the circuit board, the first positioning component 1 is used to lock the circuit board to be inserted or removed and is provided with an insertion / removal station. The first positioning component 1 includes at least a first positioning unit 11 and a second positioning unit 12 arranged opposite each other. The first positioning unit 11 and the second positioning unit 12 are arranged side-by-side with intervals. The length of both the first positioning unit 11 and the second positioning unit 12 is greater than that of the circuit board. When inserting or removing optical modules from the circuit board, the circuit board is constrained by the first positioning unit 11 and the second positioning unit 12 of the first positioning component 1. The circuit board is a PCB board, but it can also be configured as other circuit boards capable of assembling optical modules. The PCB board has multiple optical module slots.

[0043] Reference Figure 1 As shown, the insertion / removal mechanism 2 is disposed on the support platform 13 and is used to move and insert / remove the optical module between the second positioning component 5 and the insertion / removal station, respectively. Specifically, the insertion / removal mechanism 2 includes: a robot arm 21 disposed on one side of the positioning mechanism, a second clamping component connected to the output end of the robot arm 21, and an identification unit 24 disposed on one side of the second clamping component. The robot arm 21 is used to drive the second clamping component to move to insert the optical module onto the circuit board or remove the optical module from the circuit board. Therefore, the range of motion of the robot arm 21 is set to cover the first positioning component 1, the second positioning component 5, and the buffer mechanism 10. The robot arm 21 is a multi-axis industrial robot arm 21, such as a four-axis robot arm 21, a five-axis robot arm 21, or a six-axis robot arm 21. The second clamping component is used to clamp the optical module. The second clamping component includes a first clamping drive member 22 and a first clamping part 23. The first clamping drive member 22 adopts a two-finger pneumatic gripper, which can adjust the clamping force and clamping size according to the size of the optical module. The identification unit 24 is a vision identification unit. The vision identification unit 24 is used to capture the shape features of the optical module during the picking and placing process to calculate the deviation between the actual and theoretical positions of the optical module. The control system drives the robot arm 21 to perform compensating movements based on the deviation value, aligning the first gripping part 23 (the gripper) of the second gripping assembly with the gripping position on the side of the optical module, and closing the gripper to complete the gripping. The robot arm 21 moves the optical module to the insertion / removal station according to a preset path and inserts the optical module into the corresponding socket on the circuit board. When removing the optical module, the robot arm 21 drives the second gripping assembly to move so that the first gripping part corresponds to the optical module on the circuit board at the insertion / removal station. The first gripping part 23 then grips the optical module and pulls it off the circuit board. The robot arm 21 then drives a position transfer and places the removed optical module at the second positioning assembly.

[0044] Reference Figures 2-4As shown, in one possible embodiment, the first positioning unit 11 and the second positioning unit 12 of the first positioning component 11 have the same structure. The first positioning unit 11 includes a support body 111 extending along a first direction, a first driving member 112 disposed on the support body 111, and a pressing member 113 connected to the output end of the first driving member 112 and capable of pressing against the circuit board to be inserted or removed. The support body 111 is disposed on a support platform. The output end of the first driving member 112 is disposed along the height direction and fixedly connected to the pressing member 113, capable of driving the pressing member 113 to move up and down along the height direction. Specifically, the support body 111 extends along the first direction, and a insertion / removal station is formed on its top surface for placing and supporting the optical module during insertion / removal.

[0045] Furthermore, a support plate 115 is connected to the inner side of the support body 111, which increases the bearing area of ​​the insertion / removal station to reduce the stress deformation of the circuit board during the insertion / removal process. The first driving member 112 is a cylinder or electric push rod, installed on the outer side of the support body 111. This installation position can effectively avoid interference between the first driving member 112 and the circuit board and support plate 115 located inside the support body 111. The pressing member 113 is L-shaped, connected to the output end of the first driving member 112 and extending horizontally in the second direction towards the inner side of the first positioning unit 11 and the second positioning unit 12. Its end away from the first driving member 112 extends downward in the height direction to form a pressing part 114. This L-shaped structure design allows the pressing member 113, driven by the first driving member 112, to stably press the circuit board from above into the insertion / removal station, that is, between the top surface of the support body 111 and the support plate 115 and the pressing part 114 of the pressing member 113, thereby fixing the circuit board. The first positioning unit 11 and the second positioning unit 12 have the same structure. The specific structure of the second positioning unit 12 can be referred to the first positioning unit 11, and will not be described again here.

[0046] Reference Figure 4As shown, the projection area of ​​the part of the pressing member 113 that is in contact with the first driving member 112 in the height direction is located within the top surface of the support body 111 and / or the support plate 115. When the pressing member 113 presses down, the area of ​​the circuit board being pressed is always supported by the support body 111 and / or the support plate 115, avoiding any suspended area below the circuit board and preventing local deformation or even breakage of the circuit board due to uneven force. To improve the pressing stability, the first positioning unit 11 and the second positioning unit 12 are respectively provided with the first driving member 112 and the pressing member 113 at both ends, and the four sets of pressing members 113 are respectively arranged at the four corners of the insertion and removal station. This ensures that the four corners of the circuit board are subjected to uniform pressing force, effectively preventing the circuit board from tilting or warping during the insertion and removal process. At the same time, the arrangement at the four corners also minimizes the interference of the pressing member 113 on the optical module insertion and removal process, ensuring that the robot arm 21 can smoothly insert and remove the optical module.

[0047] Continue to refer to Figure 4 As shown, further, the top surface height of the support plate 115 is less than the top surface height of the support body 111. In this case, the projection area of ​​the end of the pressing member 113 in the height direction is located within the top surface of the support plate 115. A stepped surface is formed between the support plate 115 and the support body 111. This stepped surface can limit the circuit board in the second direction, preventing displacement of the circuit board in the second direction during insertion and removal. The support plate 115 is located inside the support body 111. The side surface of the support body 111 guides and limits the circuit board. The support plate 115 and the support body 111 are fixedly connected by a slotted hole and bolts. The slotted hole is opened along the height direction on the side surface of the support plate 115. By adjusting the up and down position of the bolts in the slotted hole, the height difference between the support plate 115 and the support body 111 can be changed, thereby adapting to circuit boards of different thicknesses and improving the versatility of the first positioning component 1. The first driving component 112 is positioned on the outside of the support body 111 to avoid interference with the circuit board and support plate 115 located on the inside of the support body 111.

[0048] Continue to refer to Figure 2As shown, to accommodate circuit boards of different sizes, the optical module insertion / removal device also includes an insertion / removal platform 9 mounted on the support platform 13. The first positioning unit 11 and the second positioning unit 12 are both mounted on the insertion / removal platform 9. The insertion / removal platform 9 is equipped with a guide assembly 8. The second positioning unit 12 is movably connected to the insertion / removal platform 9 via the guide assembly 8 to move closer to or further away from the first positioning unit 11. Specifically, the guide assembly 8 includes support seats 83 on both sides of the insertion / removal platform 9 along a second direction, guide rods 81 with both ends connected to the support seats 83 on both sides, and a guide sleeve 82 connected to the support body 111 in the second positioning unit 12 and slidably fitted onto the guide rods 81. The axes of the two support seats 83 are on the same straight line and extend along the second direction. The guide rods 81 are fixedly connected to the support seats 83 on both sides at both ends and have sufficient structural rigidity to avoid bending deformation due to force. The guide sleeve 82 is configured as a linear bearing. There are two sets of guide assemblies 8. The two sets of guide assemblies 8 are arranged side-by-side and spaced apart on the insertion / removal platform 9 along a first direction. The guide rods 81 of the two sets of guide components 8 are parallel to each other. This dual-set arrangement can effectively limit the rotational freedom of the second positioning unit 12 during the sliding process, prevent the second positioning unit 12 from tilting or shifting, and ensure the positional accuracy and stability during the adjustment process.

[0049] Continue to refer to Figure 4As shown, a locking assembly 7 is detachably connected between the second positioning unit 12 and the insertion / removal platform 9. The locking assembly 7 is used to lock the second positioning unit 12 after the spacing adjustment is completed. Specifically, the locking assembly 7 includes a first locking seat 71, a second locking seat 74, and a fixing member 73. After the spacing between the first positioning unit 11 and the second positioning unit 12 is adjusted to fit the size of the circuit board by the guide assembly 8, the second positioning unit 12 is locked by the locking assembly 7 to maintain this spacing. The locking assembly 7 includes: a first locking seat 71 and a second locking seat 74 respectively connected to the insertion / removal platform 9 and the second positioning unit 12; and a fixing member 73 connected to the first locking seat 71 and the second locking seat 74. The first locking seat 71 has multiple positioning holes 72 along its length that fit the fixing member 73. Specifically, the first locking seat 71 extends along a second direction and is fixedly connected to the top surface of the insertion / removal platform 9 by bolts. Its length direction is consistent with the axial direction of the guide rod 81, and it can cover the adjustment stroke range of the second positioning unit 12. The first locking seat 71 has multiple positioning holes 72 along its length. The diameter of the positioning holes 72 is adapted to the end size of the fixing member 73, ensuring that the fixing member 73 can be smoothly inserted and reliably fixed. The second locking seat 74 is L-shaped, and its vertical part is fixedly connected to the side of the support body 111 of the second positioning unit 12 by bolts. The position of the second locking seat 74 corresponds to the position of the first locking seat 71, ensuring that the two can form an effective fit. The horizontal part of the second locking seat 74 extends above the first locking seat 71 in a second direction. The bottom surface of the horizontal part maintains a preset gap or sliding fit with the top surface of the first locking seat 71 to avoid interference between the two during the sliding of the second positioning unit 12. The fixing member 73 is a rotary plunger, which is connected to the horizontal part of the second locking seat 74. The end of the rotary plunger is machined with a cylindrical structure that matches the positioning hole 72. By rotating the rotary plunger, the cylindrical structure at the end can be inserted into or pulled out of the positioning hole 72 of the first locking seat 71, thereby fixing or separating the first locking seat 71 from the second locking seat 74, and thus locking or unlocking the second positioning unit 12. The rotary plunger is also provided with a positioning buckle. When the end is inserted into the positioning hole 72, the positioning buckle can be engaged in the corresponding slot of the second locking seat 74 to prevent the rotary plunger from rotating due to vibration during operation, ensuring the reliability of the locked state.

[0050] Reference Figure 1 and Figure 3As shown, in order to inspect the circuit board on the first positioning component 1, a detection mechanism 4 is also provided on one side of the first positioning component 1. The detection mechanism 4 includes a first linear drive 41 disposed on one side of the first positioning component 1 and used for driving along a first direction, and a detection unit 42 connected to the output end of the first linear drive 41 with its detection end facing the insertion / removal station. The first linear drive 41 drives the detection unit 42 to move along the first direction, so that its detection range can cover the length of the circuit board. The insertion / removal platform 9 is provided with a detection support 43, which is disposed along the first direction, and the first linear drive 41 is mounted on the detection support 43. The detection support 43 is provided so that the height of the detection unit 42 can be aligned with the circuit board. The detection unit 42 can be configured to perform grayscale processing, edge detection, and feature extraction on the circuit board to be inserted / removed and / or the optical module already inserted on the first positioning component 1 for detection purposes. For example, it can detect whether the slots on the circuit board are intact, whether the insertion hole positions are accurate, whether the optical module is inserted correctly, and whether there is any misalignment or damage. It can also analyze whether there are scratches, breaks, stains, or other defects on the surface of the circuit board, calculate the deviation between the actual position coordinates of the insertion hole and the preset theoretical coordinates, and transmit the detection results and deviation data to the control system in real time. This ensures that only qualified circuit boards and optical modules enter or complete the insertion process, preventing unqualified products from flowing into subsequent processes. The detection unit 42 is fixedly connected to the output end of the first linear drive component 41 via a connector, and moves along a first direction under the drive of the first linear drive component 41 to detect multiple slots on the circuit board. The detection unit 42 includes a visual inspection camera and a ring light source. The visual inspection camera can acquire image information of the circuit board and optical module, the optical lens ensures image clarity and detail, and the ring light source provides a uniform and stable lighting environment, avoiding image acquisition deviations caused by insufficient light, reflection, or shadows, and ensuring the reliability of the detection data. The detection unit 42 integrates an image processing module and a data transmission module, which can process and analyze the acquired images in real time and transmit the detection results and data to the control system of the device in real time.

[0051] Reference Figure 3As shown, to inspect circuit boards of different sizes, the optical module insertion / removal device also includes a fourth linear drive 6 mounted on the support platform 13. The fourth linear drive 6 is positioned along the second direction. The fourth linear drive 6 is a linear motor. The insertion / removal platform 9 is connected to the output end of the fourth linear drive 6. The fourth linear drive 6 drives the insertion / removal platform 9 to move and adjust its position along the second direction on the support platform 13, while the detection support 43 remains stationary on the support platform 13. The support platform 13 also has a sliding pair 14 along the second direction. The insertion / removal platform 9 is movably connected to the support platform 13 along the second direction via the sliding pair 14. The sliding pair 14 includes a slide rail and a slider. The slide rail is fixedly connected to the top surface of the support platform 13 along the second direction and is parallel to the fourth linear drive 6. The slider is fixedly connected to the bottom surface of the insertion / removal platform 9. There are two sets of sliding pairs 14, respectively located on both sides of the fourth linear drive 6, forming a symmetrical support structure to ensure the stability of the insertion / removal platform 9 during movement and to prevent tilting or displacement caused by unilateral force.

[0052] Reference Figure 3 As shown, the first linear drive member 41 of the detection mechanism 4 remains in a fixed position. Because the first linear drive member 41 is fixed to the support platform 13, the insertion / removal platform 9 can move along the second direction with the fourth linear drive member 6. By adjusting the position of the insertion / removal platform 9, the relative position between the circuit board on the first positioning component 1 and the detection unit 42 can be changed, so that the focusing range of the detection unit 42 can be adapted to circuit boards of different sizes. At the same time, the first linear drive member 41 can drive the detection unit 42 to move along the first direction, so that the detection range of the detection unit 42 can completely cover multiple slot positions on the circuit board, and the focusing range of the detection unit 42 can be adapted to the circuit board, so as to completely and clearly obtain the slots on the circuit board for detection.

[0053] Reference Figure 1 As shown, a buffer mechanism 10 is also provided on the support platform 13. When an optical module is defective, the defective optical module is clamped into the buffer mechanism 10 by the insertion / removal mechanism 2 for further processing. The buffer mechanism 10 includes a buffer support 101 disposed on one side of the first positioning component 1, and a second suction member 102 connected to the end of the buffer support 101. The buffer support 101 is disposed on the side close to the first positioning component 1 to avoid interfering with the robot arm 21's insertion / removal of optical modules on the circuit board located at the insertion / removal station.

[0054] Before the insertion / removal operation, according to the specifications of the circuit board to be inserted / removed, the fourth linear drive 6 drives the insertion / removal platform 9 to move along the second direction to ensure that the circuit board to be inserted / removed is adapted to the focal length requirements of the detection unit 42 after it is moved to the first positioning component 1. The feeding mechanism 3 moves the circuit board to be inserted / removed to the insertion / removal station of the first positioning component 1. The first drive 112 drives the pressing component 113 to move downward, and then stably presses and fixes the circuit board to the insertion / removal station located on the support body 111. The insertion / removal mechanism 2 is used to remove the optical module: if the optical module is qualified, the insertion / removal mechanism 2 moves the optical module to the second positioning component 5; if the optical module is unqualified, the insertion / removal mechanism 2 moves the optical module to the buffer mechanism 10. Then, the slider of the first linear drive 41 drives the detection unit 42 to move along the first direction to the relative position of the slot on the circuit board for detection, such as detecting the PIN pins in the slot. If the slot is not damaged, the insertion / removal mechanism 2 obtains a new optical module from the second positioning component 5 and then inserts the new optical module into the slot on the circuit board. In this embodiment, the slot is arranged horizontally, and the circuit board is placed with its slot facing the side with the detection unit 42.

[0055] Reference Figure 1-3 As shown, there are two sets of first positioning components 1. When the circuit board on one of the first positioning components 1 is performing the insertion and removal of the optical module, the other first positioning component 1 can receive or output the circuit board. Through the cooperation of the two sets of first positioning components 1, the seamless connection of processes such as circuit board transfer, positioning and fixing, optical module insertion and removal, and finished product output is achieved, optimizing the working cycle of the robot 21 and reducing waiting time. Each set of first positioning components 1 is independently configured with a complete structural unit, and each includes a first positioning unit 11 and a second positioning unit 12 arranged opposite to each other. Each first positioning unit 11 and second positioning unit 12 includes a support body 111, a support plate 115, a first driving component 112, and a pressing component 113. The guide component 8 and locking component 7 of each set of components operate independently.

[0056] The feeding mechanism 3 is disposed on one side of the first positioning component 1 on the support platform 13 and is at least used to move the circuit board to be inserted or removed from the input end of the first positioning component 1 to the insertion / removal station or to remove the inserted circuit board from the insertion / removal station. Specifically, the feeding mechanism 3 includes: a third linear drive 33 disposed on one side of the first positioning component 1 and capable of being driven along a first direction, and a first clamping component connected to the output end of the third linear drive 33. The first clamping component is at least used to clamp the circuit board to be inserted or removed to move it to the insertion / removal station, and can also be used to remove the circuit board from the insertion / removal station.

[0057] Reference Figure 4As shown, the output end of the third linear drive 33 is connected to a bracket 31. The end of the bracket 31 extends along the second direction between the first positioning unit 11 and the second positioning unit 12. The first clamping assembly is connected to the end of the bracket 31. To avoid interference with the circuit board, the third linear drive 33 is also disposed on the outside of the support body 111. The bracket 31 is connected to the output end of the third linear drive 33, and the bracket 31 crosses over the support body 111 and extends between the first positioning unit 11 and the second positioning unit 12, so that the first clamping assembly can be positioned approximately between the first positioning unit 11 and the second positioning unit 12, that is, approximately corresponding to the middle position of the circuit board. The height of the first clamping assembly is adapted to the height of the circuit board, which can move the circuit board to the insertion / removal station.

[0058] Reference Figure 4 As shown, the first clamping assembly includes a second clamping drive 32 connected to the end of the bracket 31, and a second clamping part 34 connected to the end of the second clamping drive 32. The second clamping drive 32 is a pneumatic finger cylinder or an electric gripper, with adjustable stroke, and can adapt to different circuit boards by preset clamping stroke. The second clamping part 34, as the part that directly contacts the circuit board, is detachably connected to the output end of the second clamping drive 32 by bolts or the like, which facilitates changing the model according to the shape of the circuit board. The structural shape of the second clamping part 34 is designed according to the edge characteristics of the circuit board to be inserted or removed, such as a PCB board. For flat circuit boards without protrusions, symmetrically arranged L-shaped clamping arms are used, and the inner contact surface of the clamping arms is processed into a plane that matches the edge of the circuit board; for circuit boards with positioning holes 72 or protrusions on the edge, the inner side of the clamping arm is provided with a relief groove or positioning boss that matches the characteristics of the circuit board to avoid pressing on the circuit board structure during clamping. The contact surface of the second clamping part 34 can be inlaid with a soft, wear-resistant material, specifically fluororubber or polyurethane elastomer. This material can increase the contact area with the circuit board through elastic deformation, thereby improving clamping friction, and can also buffer the impact of clamping force on the circuit board surface, preventing edge chipping or surface scratches on brittle circuit boards such as PCBs. In addition, the contact surface of the second clamping part 34 is also provided with anti-slip textures, which further enhances clamping stability without damaging the circuit board surface and prevents the circuit board from axially slipping due to inertia during transfer.

[0059] To ensure clamping accuracy, a positioning pin hole is provided at the connection between the second clamping drive 32 and the second clamping part 34. The coaxiality of the two is calibrated by the positioning pin, preventing uneven force when the clamping part contacts the circuit board due to connection deviation. A reinforcing rib is provided at the extended end of the bracket 31 corresponding to the installation position of the second clamping drive 32. The reinforcing rib extends along the length of the bracket 31 and has the same thickness as the main body of the bracket 31. It is used to distribute the torque generated when the drive and clamping parts are working, to prevent bending deformation of the end of the bracket 31 due to concentrated load, and to ensure the positional accuracy of the clamping assembly during the transfer process.

[0060] Reference Figure 2 As shown, the second positioning component 5 is used to place the optical module. The second positioning component 5 is disposed on the support platform 13. There are two second positioning components 5, which can be used to place the optical module and temporarily place the optical module after it is removed. When the first positioning component 1 and the second positioning component 5 respectively have a circuit board to be inserted or removed and an optical module, the optical module is moved and inserted or removed between the second positioning component 5 and the insertion / removal station by the insertion / removal mechanism 2.

[0061] The second positioning component 5 includes: a positioning support 51 disposed on one side of the first positioning component 1, and a first suction member 52 installed on the positioning support 51. The first suction member 52 is used to accommodate the optical module. Both the first suction member 52 and the second suction member 102 have positioning grooves. To ensure that the optical module is stably placed in the positioning groove, multiple suction holes for providing negative pressure are provided in the positioning groove. The number of suction holes is determined according to the size and weight of the optical module, ensuring that the suction force can evenly cover the surface of the optical module and avoid excessive local force that could cause deformation of the optical module. The diameter of the suction holes is small, and the openings of the suction holes and the grooves of the positioning grooves are chamfered to avoid scratching the surface of the optical module. Both the buffer support 101 and the positioning support 51 have air channels inside. One end of the air channel is connected to each suction hole, and the other end is connected to an external negative pressure generating device, such as a vacuum pump, through an air pipe. An electromagnetic control valve is installed on the air pipe to control the negative pressure on and off of the suction holes. The inner wall surface of the positioning groove is smooth to avoid scratching the surface of the optical module.

[0062] To optimize the overall structural space of the optical module insertion / removal device, the detection mechanism 4 is fixedly mounted on the support platform 13. The first positioning component 1 and the feeding mechanism 3 are synchronously mounted on the support platform 13 via the fourth linear drive component 6. The detection unit 42 in the detection mechanism 4 and the first clamping component of the feeding mechanism 3 can both move along the first direction, while the insertion / removal platform 9 can move along the second direction. Furthermore, the feeding mechanism 3 is positioned close to the first positioning unit 11 to prevent the bracket 31 from interfering with the adjustment of the second positioning unit 12, or to prevent the bracket 31 from being too long and prone to deformation and wobbling, thus affecting clamping accuracy.

[0063] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
