Description

Technical Field

[0001] This application relates to the field of optical module manufacturing equipment technology, specifically to a glue-separating fixture and glue-separating method for optical module adhesives. Background Technology

[0002] In the field of optical module manufacturing, the common practice for dispensing adhesive from a cartridge to other containers is as follows: an operator holds the cartridge and manually presses the piston rod at its end, controlling the pressure and time based on experience to allow the adhesive to flow out. Specifically, this method involves the operator applying direct force to the cartridge piston to extrude the adhesive. The basic working principle is that hand pressure is transmitted through the piston rod to the adhesive inside the cartridge, overcoming flow resistance and forcing it out of the outlet. This method has been used for a long time primarily because it is straightforward, requires no additional specialized tools, and meets basic usage needs when precise dispensing accuracy is not critical.

[0003] However, this solution relies entirely on manual feel, which inevitably affects the stability and quantifiability of the glue output, and may even lead to material waste and process fluctuations due to excessive or insufficient glue. It cannot meet the requirements of production sites that have precise and repeatable control over the glue output per batch. Summary of the Invention

[0004] This application provides a glue dispensing fixture and method for optical module adhesives, which solves the problem in related technologies where the glue dispensing amount cannot be accurately controlled during manual glue dispensing, which easily leads to glue waste.

[0005] To achieve the above objectives, the embodiments of this application disclose the following technical solutions: In a first aspect, embodiments of this application provide a dispensing fixture for adhesive used in optical modules, including a support structure, an extrusion mechanism, and a limiting member. The support structure supports an adhesive cartridge to be dispensed. The extrusion mechanism is arranged along a first direction with the support structure. The extrusion mechanism includes a pressure head, which is movably disposed relative to the support structure along the first direction to switch between an initial position and a maximum adhesive volume position. During the movement of the pressure head from the initial position to the maximum adhesive volume position, it is adapted to abut against the adhesive cartridge to dispensing adhesive from the cartridge. The extrusion mechanism has an abutment portion. The limiting member and the abutment portion are movable relative to each other along the first direction. In the initial position, the limiting member and the abutment portion are spaced apart, and in the maximum adhesive volume position, the limiting member and the abutment portion abut against each other.

[0006] In this embodiment, by providing a limiting member that is movable relative to the contact portion along a first direction, and by ensuring that the limiting member abuts the contact portion at the maximum glue volume position, the mechanical abutting action between the limiting member and the contact portion can limit the endpoint of the pressure head's travel to a fixed physical position, thereby fixing the maximum amount of glue dispensed in a single operation. This achieves precise and stable control over the amount of glue dispensed from the glue cartridge in a single operation, avoiding inconsistencies in glue dispensing or glue waste caused by an unclear endpoint.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In the embodiments of this application, the terms "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0030] In the description of the embodiments of this application, the term "multiple" means two or more.

[0031] In the description of the embodiments of this application, the term "and / or" refers to and covers any and all possible combinations of one or more of the associated listed items. The term "and / or" describes an association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "or" relationship.

[0032] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0033] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0034] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism can be, for example, within ±10°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity can also be, for example, within ±10°; “equal” includes absolute equality and approximate equality, where the acceptable deviation range for approximate equality can be, for example, a difference between the two equals less than or equal to 5% of either one.

[0035] As mentioned in the background section above, in the field of optical module manufacturing, the common practice for dispensing adhesive from a cartridge to other containers is as follows: the operator holds the cartridge and manually presses the piston rod at its end, controlling the pressure and time based on experience to allow the adhesive to flow out. Specifically, this method uses the operator's hand to directly apply force to the cartridge piston to extrude the adhesive. Its basic working principle is that the hand pressure is transmitted through the piston rod to the adhesive inside the cartridge, overcoming the flow resistance and causing it to exit from the outlet. This method has been used for a long time primarily because it is straightforward, requires no additional specialized tools, and meets basic usage needs in applications where precise dispensing accuracy is not critical.

[0036] However, this solution relies entirely on manual feel, which inevitably affects the stability and quantifiability of the glue dispensing amount, and may even lead to material waste and process fluctuations caused by excessive or insufficient glue. It cannot meet the production scenarios that require precise and repeatable control of the glue dispensing amount per batch. For example, in the production of optical modules, the production line needs to dispense glue in quantitative quantities according to the daily production capacity to avoid waste, and its performance is not ideal.

[0037] For the above technical issues, please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a dispensing fixture 100 for optical module adhesive provided in this application. This application provides a dispensing fixture 100 for optical module adhesive, including a supporting structure 1, an extrusion mechanism 2, and a limiting member 3. The supporting structure 1 is used to support the adhesive cartridge 200 to be dispensed. The extrusion mechanism 2 and the supporting structure 1 are arranged along a first direction. For example, in… Figure 1 In the illustrated embodiment, the first direction is the direction of gravity (i.e., the vertical direction), with the supporting structure 1 located below and the compression mechanism 2 located above. It can be understood that in other embodiments, the first direction may also be set to horizontal or other directions depending on actual installation and operational requirements.

[0038] The extrusion mechanism 2 includes a pressure head 21. Along a first direction, the pressure head 21 is movably disposed relative to the support structure 1 to switch between an initial position and a maximum glue volume position. During the movement of the pressure head 21 from the initial position to the maximum glue volume position, it is adapted to abut against the piston or end of the glue cartridge 200 to discharge glue from the glue cartridge 200. It is understood that the shape of the end face of the pressure head 21 that contacts the glue cartridge 200 can be adapted to the shape of the piston or end of the glue cartridge 200, for example, a flat surface, a spherical surface, or a grooved shape.

[0039] The extrusion mechanism 2 also has an abutment portion 2a. The limiting member 3 and the abutment portion 2a are movable relative to each other in a first direction. In the initial position, the limiting member 3 and the abutment portion 2a are spaced apart. In the position of maximum adhesive content, the limiting member 3 and the abutment portion 2a abut against each other.

[0040] In this way, by setting a limiting member 3 that is movable relative to the contact portion 2a in the first direction, and by ensuring that the limiting member 3 stops the contact portion 2a at the maximum glue volume position, the mechanical stopping action between the limiting member 3 and the contact portion 2a can limit the end point of the travel stroke of the pressure head 21 to a fixed position, thereby fixing the maximum amount of glue dispensed in a single operation. This achieves precise and stable control of the glue volume dispensed from the glue cartridge 200 in a single operation, avoiding problems such as inconsistent glue dispensing or glue waste caused by an unclear end point of the travel stroke.

[0041] In some embodiments, the limiting member 3 is fixed relative to the pressure head 21. Here, "the limiting member 3 is fixed relative to the pressure head 21" means that when the pressure head 21 moves from the initial position to the position of maximum adhesive volume or moves in the opposite direction, the limiting member 3 and the pressure head 21 always maintain synchronous movement, and their relative positions in the first direction remain unchanged.

[0042] This configuration allows the movement of the limiting member 3 to be synchronized with the movement of the pressure head 21, thus enabling the relative positional relationship between the limiting member 3 and the contact portion 2a to directly and accurately reflect the relationship of the pressure head 21 relative to the position of maximum adhesive volume. This makes the limit control of the pressure head 21's stroke more direct and reliable, and simplifies the motion correlation structure between the limiting member 3 and the pressure head 21.

[0043] It is understandable that the fixed relative position of the limiting member 3 to the pressure head 21 is only one example of the setting of the limiting member 3. In other embodiments, the limiting member 3 may also be fixed relative to the bearing structure 1 of the bearing platform. In this case, the abutment part 2a should be set on the pressure head 21 or a component that moves synchronously with the pressure head 21.

[0044] Please see Figure 1In some embodiments, the extrusion mechanism 2 includes a support platform 22 and a sliding rod 23. The sliding rod 23 is slidably disposed on the support platform 22 along a first direction, and the pressure head 21 is fixedly connected to one end of the sliding rod 23 near the support structure 1. Exemplarily, the connection between the pressure head 21 and the sliding rod 23 can be integrally formed or a separate structure. When the pressure head 21 and the sliding rod 23 are separate structures, the pressure head 21 and the sliding rod 23 can be fixedly connected by means of threaded connection, snap-fit, or welding.

[0045] The limiting member 3 is provided on the sliding rod 23, and the abutting part 2a is formed on the support platform 22. For example, the abutting part 2a can be the upper surface of the support platform 22 near the support structure 1, or it can be the edge of a boss or groove machined on the upper surface or side wall of the support platform 22, or a separate stop block fixedly installed on the support platform 22.

[0046] This configuration, by fixing the pressure head 21 to the sliding rod 23 slidably mounted on the support platform 22 along the first direction, and by configuring the sliding rod 23 to slide in conjunction with the support platform 22, ensures the linearity and stability of the pressure head 21's movement. Simultaneously, by providing the limiting member 3 on the sliding rod 23 and forming the abutment portion 2a on the support platform 22, the mechanical stop structure for limiting the stroke is integrated into the linear motion mechanism formed by the sliding rod 23 and the support platform 22. This not only provides a stable motion basis for precise glue dispensing but also makes the structure of the glue dispensing fixture 100 for optical modules more compact and rational.

[0047] Please see Figure 1 In some embodiments, the extrusion mechanism 2 further includes a connecting plate 24, and the limiting member 3 is connected to the sliding rod 23 via the connecting plate 24. For example, the connecting plate 24 is fixedly connected to the end of the sliding rod 23 away from the supporting structure 1. The connecting plate 24 and the sliding rod 23 can be integrally formed or separate structures. When the connecting plate 24 and the sliding rod 23 are separate structures, they can be fixedly connected by means of snap-fit, screw connection, or other methods.

[0048] With this configuration, the connecting plate 24 serves as a connecting medium to connect the limiting member 3 and the sliding rod 23. This eliminates the need to directly machine a complex structure on the sliding rod 23 for mounting the limiting member 3, reducing the machining requirements on the sliding rod 23 and making the installation and removal of the limiting member 3 more convenient.

[0049] It is understandable that connecting the limiting member 3 and the sliding rod 23 via the connecting plate 24 is the preferred method. In other alternative embodiments, the limiting member 3 can also be directly connected to the sliding rod 23, for example, by opening a threaded hole in the sliding rod 23 and screwing the limiting member 3 (such as a bolt) directly into the side wall of the sliding rod 23; or by using clamps, fasteners, or other means to directly fix the limiting member 3 to the sliding rod 23.

[0050] Please see Figure 1 In some embodiments, the limiting member 3 is a bolt. For example, the bolt can be a hexagonal head bolt, an internal hexagonal head bolt, or an adjusting bolt with a handle, etc. The connecting plate 24 has a threaded through hole 241 extending through the connecting plate 24. The limiting member 3 is threadedly engaged with the threaded through hole 241.

[0051] With this configuration, by setting the limiting member 3 as a bolt and threading the bolt into the threaded through hole 241 of the connecting plate 24, the transmission and self-locking characteristics of the threaded engagement can be utilized to achieve precise and continuous adjustment of the bolt's position relative to the connecting plate 24. Since the limiting member 3 is connected to the sliding rod 23 through the connecting plate 24, adjusting the position of the bolt is equivalent to adjusting the position of the mechanical stop point used to limit the stroke of the pressure head 21, thereby enabling fine setting and flexible adjustment of the maximum glue volume position.

[0052] Of course, this application is not limited to this. In other embodiments, the limiting member 3 can be a pin, and the connecting plate 24 is provided with a corresponding pin hole, and the position is fixed by a pin.

[0053] Please see Figure 1 In some embodiments, the extrusion mechanism 2 further includes a guide rod 27. Exemplarily, the guide rod 27 may be an optical axis, a guide post, or a screw, and the number of guide rods 27 may be one, two, or more.

[0054] The guide rod 27 is located on the side of the support platform 22 away from the support structure 1 and is fixedly connected to the support platform 22. For example, the fixed connection between the guide rod 27 and the support platform 22 can be as follows: the lower end of the guide rod 27 is provided with an external thread, which engages with a threaded hole on the support platform 22 for locking; or the lower end of the guide rod 27 is pressed into the hole of the support platform 22 by an interference fit; or the guide rod 27 is fixed to the upper surface of the support platform 22 by screws and pressure plates.

[0055] The connecting plate 24 has a guide hole 242, and the guide rod 27 slides within the guide hole 242. This allows the sliding rod 27 to provide additional guidance and constraint on the movement path of the connecting plate 24 and the connected sliding rod 23 when the sliding rod 23 drives the pressure head 21 and the connecting plate 24. This enhances the straightness and stability of the sliding rod 23 and the pressure head 21 along the first direction, preventing wobbling during movement and ensuring smooth and precise glue discharge.

[0056] Please see Figure 1 In some embodiments, a scale line 231 is provided on the outer peripheral surface of the sliding rod 23, and a portion of the scale line 231 is opposite to the limiting member 3 in a direction perpendicular to the first direction. Exemplarily, the scale line 231 can be formed on the surface of the sliding rod 23 by engraving, etching, printing, or attaching a ruler. The unit of the scale line 231 can be a length unit such as millimeters (mm) or centimeters (cm), or it can be a volume unit of adhesive calculated based on the cross-sectional area of ​​the pressure head 21 and the displacement of the sliding rod 23. The phrase "a portion of the scale line 231 is opposite to the limiting member 3" means that when viewed from a direction perpendicular to the first direction (e.g., horizontal), a portion of the limiting member 3 (such as the end face or side of a bolt) is on the same visual alignment line as certain scale lines 231 on the sliding rod 23. The operator can use the edge or end face of the limiting member 3 as a "vernier" to read the aligned scale value. The limiting member 3 itself can also have a sharp indicator mark for more precise alignment of the scale line 231.

[0057] In this way, the scale line 231 can be used to provide a visual reference for the displacement of the sliding rod 23. When the position of the limit member 3 is adjusted or the sliding rod 23 moves, the operator can observe the reading of the scale line 231 opposite to the limit member 3, thereby intuitively understanding or setting the parameters related to the stroke of the sliding rod 23, making the control process of the dispensing volume more visual and easier to operate.

[0058] Please see Figure 2 In some embodiments, the sliding rod 23 is provided with a rack 232 extending along a first direction. The pressing mechanism 2 includes a gear 25 and a drive member 26. The gear 25 is rotatably connected to the support platform 22 along a second direction and meshes with the rack 232. The second direction is perpendicular to the first direction; that is, the shaft of the gear 25 is arranged in a horizontal direction. The drive member 26 is connected to the gear 25 to drive the gear 25 to rotate.

[0059] With this configuration, by providing a rack 232 extending along the first direction on the sliding rod 23, and providing a gear 25 meshing with the rack 232 and a drive member 26 connected to the gear 25, the rotational motion of the drive member 26 driving the gear 25 can be converted into linear motion of the sliding rod 23 along the first direction through the meshing transmission between the gear 25 and the rack 232. This allows for the pressure head 21 to compress the rubber cylinder 200 with a smaller operating force, achieving a labor-saving operation.

[0060] Please see Figure 2 In some embodiments, the support platform 22 has a receiving cavity 221 and a through hole 222 extending through the two side walls of the support platform 22 in a first direction. The receiving cavity 221 is connected to the through hole 222. The gear 25 is disposed in the receiving cavity 221 and the rack 232 passes through the through hole 222.

[0061] This configuration, by having the support platform 22 have a receiving cavity 221 and a through hole 222 communicating with the receiving cavity 221, and by placing the gear 25 inside the receiving cavity 221 and having the rack 232 pass through the through hole 222, allows the gear 25 to be accommodated and protected within the internal space of the support platform 22. This not only makes the overall structure of the extrusion mechanism 2 more compact, but also provides a stable movement channel for the gear 25 and rack 232 using the receiving cavity 221 and the through hole 222, helping to ensure the accuracy and reliability of the meshing transmission.

[0062] Please see Figure 2 In some embodiments, the drive member 26 is a handle and is located outside the receiving cavity 221. One end wall of the support platform 22 along the second direction has a connecting hole (not shown). The pressing mechanism 2 also includes a connecting shaft (not shown). One end of the connecting shaft passes through the connecting hole into the receiving cavity 221 and is fixedly connected to the gear 25. Exemplarily, the fixed connection between the connecting shaft and the gear 25 can be a key connection, a pin connection, an interference fit, or fixed by a set screw.

[0063] The other end of the connecting shaft is fixedly connected to the handle. For example, the fixed connection between the connecting shaft and the handle can be a threaded connection, an interference fit, or a pin fixation. The handle extends in a direction perpendicular to the second direction. For example, the handle can be a straight handle, a ball-end handle, or a folding handle.

[0064] With this configuration, by specifically setting the drive component 26 as a handle located outside the receiving cavity 221, and by providing a connecting shaft passing through the connecting hole of the support platform 22 to connect the handle to the gear 25 inside the receiving cavity 221, the operator can transmit rotational motion to the gear 25 via the connecting shaft when operating the handle outside the support platform 22. Since the handle extends in a direction perpendicular to the second direction, an operating lever can be formed. Thus, the lever principle can be used to drive the gear 25 to rotate in a more effortless manner, thereby further reducing the operating force required to drive the sliding rod 23 and the pressure head 21.

[0065] Of course, this application is not limited to this. In other embodiments, the drive element 26 may also be a handwheel, a crank, or a motor.

[0066] Please return to the reference. Figure 1 In some embodiments, the adhesive dispensing fixture 100 for optical modules further includes a base 4 and a support column 5. The support column 5 is erected on the base 4, the bearing structure 1 is fixedly connected to the base 4, and the bearing platform 22 is mounted on the support column 5.

[0067] In this way, by setting up the base 4 and the support column 5 erected on the base 4, and fixing the bearing structure 1 to the base 4, and installing the bearing platform 22 on the support column 5, a shared and stable mounting foundation can be provided for the bearing structure 1 and the bearing platform 22. This ensures a stable relative relationship between the position of the bearing structure 1 supporting the glue cylinder 200 and the mounting position of the bearing platform 22 of the extrusion mechanism 2 through the base 4 and the support column 5, thereby ensuring the structural rigidity and stability of the entire glue dispensing fixture in the working state, and providing reliable support for precise glue dispensing operations.

[0068] Please see Figure 1 Based on the above embodiment, the support platform 22 is slidably mounted on the support column 5 along the first direction. This allows the support platform 22, along with the sliding rod 23 and pressure head 21 mounted thereon, to be adjusted in position relative to the base 4 and the support structure 1 fixed to the base 4 in the first direction. In this way, the initial relative distance between the pressure head 21 and the glue cylinder 200 placed on the support structure 1 can be flexibly adjusted according to the specific dimensions or initial state of the glue cylinder 200, thereby enhancing the adaptability of the glue dispensing fixture to different working conditions.

[0069] For example, the support column 5 can be a cylindrical guide column, a square column, or a screw. The support platform 22 can be provided with sliding holes or sliding sleeves that match the cross-sectional shape of the support column 5. To achieve locking after sliding, a locking screw can be provided on the support platform 22. After adjusting to the appropriate position, the locking screw can be tightened to make it press against the surface of the support column 5; or a clamping block, quick clamp, or other method can be used for locking.

[0070] Please see Figure 1 and combined Figure 3 In some embodiments, the supporting structure 1 includes a support frame 11 and a carrier 12; for example, in Figure 1 In the illustrated embodiment, the support frame 11 is fixedly connected to the base 4. For example, the support frame 11 and the base 4 can be fixedly connected by bolts, snap-fit, or other means.

[0071] The carrier 12 is detachably connected to the support frame 11. The carrier 12 has a loading hole 121 extending through the carrier 12 in a first direction, and the loading hole 121 is adapted to carry the rubber tube 200. In this way, the rubber tube 200 can be carried by the carrier 12 with the loading hole 121. Since the carrier 12 is detachably connected to the support frame 11, the loading and unloading of the rubber tube 200 can also be made simple and quick.

[0072] Please see Figure 3 In some embodiments, the supporting structure 1 further includes a variety of receiving blocks 13, each of which is adapted to the loading hole 121. Each receiving block 13 has a receiving hole 131 for receiving the rubber tube 200. The specifications of the receiving hole 131 are different for different types of receiving blocks 13.

[0073] In this way, when it is necessary to adapt to rubber tubes 200 of different diameters, it is only necessary to replace the receiving block 13 with the corresponding receiving hole 131 in the loading hole 121, without having to replace the entire carrier 12. In this way, the adaptation of the load-bearing structure 1 to rubber tubes 200 of different specifications is achieved in a more economical and flexible manner, thereby reducing the cost of use and maintenance.

[0074] Please see Figure 3 In some embodiments, the carrier 12 further has a fixing hole 122 communicating with the loading hole 121, the fixing hole 122 extending radially along the loading hole 121. The supporting structure 1 also includes a locking member 14, which passes through the fixing hole 122 and abuts against the receiving block 13 within the loading hole 121. Exemplarily, the fixing hole 122 can be a threaded hole, and the locking member 14 can be a matching screw or bolt.

[0075] With this configuration, the carrier 12 also has a fixing hole 122 that communicates with the loading hole 121 and extends radially along the loading hole 121, and a locking fastener 14 is provided through the fixing hole 122. The locking fastener 14 can be used to radially abut against the receiving block 13 placed in the loading hole 121. In this way, when the receiving block 13 is placed in the loading hole 121, tightening the locking fastener 14 to make it abut against the receiving block 13 can quickly fix the receiving block 13 in the loading hole 121, preventing the receiving block 13 from moving or loosening during the operation of the glue dispensing fixture, thereby ensuring the stability of the glue cylinder 200 in the placement position.

[0076] Please see Figure 4 , Figure 4 This application provides a flowchart illustrating a method for separating adhesive for optical modules. The embodiment of this application also provides a method for separating adhesive for optical modules, which uses the adhesive separating fixture 100 described in any of the above embodiments to separate the adhesive from the adhesive cartridge 200. The method includes the following steps: S10: Install the glue cartridge 200 to be dispensed onto the supporting structure 1; S20: Place the dispensing cartridge on the side of the cartridge 200 to be dispensed away from the pressure head 21 along the first direction; S30: Control the pressure head 21 to move toward the bearing structure 1 in the first direction until the limiting member 3 abuts against the abutting part 2a.

[0077] Since the adhesive separation method for optical modules provided in this embodiment uses the adhesive separation fixture 100 for optical modules as described in any of the previous embodiments, both methods can solve the same technical problem and achieve the same beneficial effects. Therefore, the beneficial effects of the adhesive separation method for optical modules provided in this application embodiment can be found in the beneficial effects of the adhesive separation fixture 100 for optical modules, and will not be repeated here.

[0078] In some embodiments, the adhesive dispensing fixture 100 for optical modules is an adhesive dispensing fixture 100 for optical modules having a receiving block 13; the step of installing the adhesive cartridge 200 to be dispensed onto the supporting structure 1 includes: The first step is to select a matching receiving block 13 according to the specifications of the glue cartridge 200 to be dispensed, and install the glue cartridge 200 to be dispensed into the receiving hole 131 of the selected receiving block 13. The second step is to install the receiving block 13 into the loading hole 121 of the carrier 12; The third step is to install the vehicle 12 onto the support frame 11.

[0079] Finally, it is necessary to explain that the complete implementation process of the adhesive separation method for optical modules is shown below: Step 1: Based on the target glue dispensing amount, and in conjunction with the scale line 231 on the sliding rod 23, adjust the position of the limiting member 3 to set the maximum downward stroke of the pressure head 21 (i.e., the maximum glue dispensing position). Step 2: Select a matching receiving block 13 according to the specifications of the glue dispensing tube 200, and insert the glue dispensing tube 200 into the receiving hole 131 of the receiving block 13.

[0080] Step 3: Place the receiving block 13 into the loading hole 121 of the carrier 12 and lock it in place with the fastener 14, so that the dispensing port of the glue cylinder 200 to be dispensed faces downward.

[0081] Step 4: Place an empty glue tube directly below the glue outlet of glue tube 200 to catch the dispensed glue.

[0082] Step 5: Operate the extrusion mechanism 2 to move the pressure head 21 downwards and begin to extrude the glue in the glue cylinder 200. The pressure head 21 continues to press down until the limiting member 3 on the connecting plate 24 abuts against the abutting part 2a on the support platform 22.

[0083] Step Six: After holding the glue container for a moment to ensure all glue has been drained, operate the extrusion mechanism 2 to return the pressure head 21 to its initial position. At this point, the predetermined amount of glue has been extruded into the empty glue cartridge below. Remove the glue cartridge to complete one quantitative glue dispensing operation. If you need to dispense glue again or change the glue cartridge size 200, repeat steps one through six above.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications or equivalent substitutions made within the spirit and principles of this application should be included within the protection scope of this application.
