Description

Technical Field

[0001] This utility model relates to an auxiliary device for assembling a sheet metal shell for a four-point optical module, specifically to a four-point optical module sheet metal shell assembly equipment, and belongs to the technical field of optical communication module devices. Background Technology

[0002] Sheet metalworking is a comprehensive cold-working process for thin metal sheets, characterized by a consistent thickness for the same part. Sheet metal parts are lightweight, high-strength, conductive, low-cost, and suitable for mass production, making them widely used in communications, electronics, and other fields. In optical communication applications, sheet metal parts are an indispensable component of optical communication modules. To meet the high-quality, fast-paced requirements of production lines, efficient assembly of sheet metal parts is necessary. However, in existing sheet metal assembly processes, the small snap-fit ​​points make it difficult to snap the parts into ideal positions. Therefore, there is an urgent need to design and develop an auxiliary fixture that can achieve high-quality and efficient rapid assembly of sheet metal parts, which can not only improve the assembly speed and quality of sheet metal parts but also ensure the appearance requirements of optical module products.

[0003] In the prior art, utility model CN219562777U discloses an auxiliary device for assembling sheet metal housings of optical modules, including a base plate, a handle, and a clamping device. An optical module fixing part is provided on the base plate, and the clamping device is provided at the corresponding fastening points of the optical module. The handle is used to operate the clamping device to press the fastening points, which solves the problem of difficulty in positioning the optical module sheet metal housing during assembly, while also achieving convenient operation and reduced usage costs. However, because this utility model only addresses two fastening points on the optical module and does not provide a method for assembling a sheet metal housing with four fastening points in one go, the following problems still exist if a four-fastening-point optical module sheet metal housing is to be assembled:

[0004] 1. The existing clamping device does not correspond to the positions of the remaining two fastening points, making it impossible to assemble the sheet metal shell of the four-fastening optical module.

[0005] 2. Even ignoring the issue of mismatched positions, secondary assembly is still required, which reduces assembly efficiency.

[0006] In practical use, because the return spring is connected to the handle, and the handle is rotatably mounted on the base plate, the return spring cannot extend or retract linearly during use (especially when compressed). The extension / retraction path is at an angle to the spring's inherent direction, making it prone to breakage and requiring frequent replacements. This not only affects assembly efficiency but also increases operating costs. Furthermore, replacing the return spring mid-process increases assembly time, further impacting efficiency and causing even greater economic losses. Currently, no technical solution exists to address these or related problems. Utility Model Content

[0007] The purpose of this invention is to utilize the rotation of a pressure rod to control the two arms of a U-shaped clamping device located on both sides of the optical module fixing part to simultaneously act on the four fastening points on the optical module, thereby achieving one-time assembly of the four-fastening point optical module sheet metal shell. At the same time, it solves the problem of easy breakage of the reset spring in the prior art. This not only improves the assembly efficiency of the four-fastening point optical module sheet metal shell, but also saves on usage costs, thus achieving cost reduction and efficiency improvement.

[0008] This utility model is achieved through the following technical solution: an auxiliary device for assembling a sheet metal shell of a four-point optical module, including a base plate with an optical module fixing part, two U-shaped clamping devices, and a pressure rod that cooperates with the clamping devices. The two clamping devices are respectively disposed on both sides of the optical module fixing part and are slidably connected to the optical module fixing part in the width direction. The two arms of the clamping devices are respectively disposed corresponding to the two fastening points of the optical module on one side. The pressure rod is rotatably disposed on the base plate and cooperates with the clamping device on the same side.

[0009] Preferably, a return spring for connecting the base plate is provided on the inner side of the bow portion of the clamping device, and the return spring is perpendicular to the side wall of the optical module.

[0010] Preferably, the optical module fixing part has rotating shafts on both sides of one end, one end of the pressure rod is sleeved on the rotating shaft, the other end of the pressure rod extends to the other end of the optical module fixing part, and the ends of the two arms of the clamping device rotate with the pressure rod to act on the corresponding fastening points of the optical module.

[0011] Preferably, the ends of the two arms of the clamping device are provided with top blocks that cooperate with the fastening points of the optical module.

[0012] Preferably, the optical module fixing part includes a front stop block that limits the front end of the optical module, a rear stop block that limits the rear end of the optical module, and side stops block respectively disposed on both sides of the optical module, and forms guide structures on both sides of the optical module for use by the two arms of the clamping device respectively.

[0013] Preferably, the outer wall of the side stop block is provided with a groove that is recessed inward therein, one end of the reset spring is fixed in the groove, and the other end is connected to the inner side of the bow of the clamping device.

[0014] Preferably, the groove is perpendicular to the side wall of the optical module.

[0015] Preferably, the outer wall of the clamping device bow corresponding to the return spring is provided with a protrusion that cooperates with the pressure rod.

[0016] Preferably, the pressure rod is provided with a handle extending outward from the base plate.

[0017] Preferably, the pressure rod is further provided with a limiting device to limit its opening and closing width.

[0018] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0019] (1) This utility model uses two U-shaped clamping devices respectively set on both sides of the optical module fixing part and slidably set in the width direction of the optical module fixing part. The two arms of the clamping device are respectively set to correspond to the two fastening points on the optical module on one side. That is, the two arms of the two clamping devices correspond to the four fastening points on both sides of the optical module. Then, by rotating the pressure rod set on the base plate and cooperating with the clamping device on the same side, that is, by rotating the pressure rod, the clamping device slides towards the optical module fixing part, so that the ends of the two arms of the two clamping devices act on the four fastening points of the optical module respectively, thereby realizing the one-time assembly of the four fastening point optical module sheet metal shell, which improves the assembly efficiency.

[0020] (2) This utility model provides a reset spring connected to the base plate on the inner side of the bow of the clamping device. The reset spring connecting the base plate and the inner side of the bow of the clamping device enables the clamping device to automatically reset after the fastening point is engaged, thereby improving the convenience and practicality of operation. In addition, by setting the reset spring perpendicular to the side wall of the optical module, it can ensure that the extension and retraction direction of the reset spring is consistent with the sliding direction of the clamping device, thereby preventing the reset spring from having an excess angle when it extends and retracts, and thus avoiding the purpose of extending the service life of the reset spring due to long-term non-use.

[0021] (3) This utility model provides rotating shafts on both sides of one end of the optical module fixing part, and then sleeves one end of the pressure rod on the rotating shaft. The other end of the pressure rod extends to the other end of the optical module fixing part, so that the ends of the two arms of the clamping device can rotate with the pressure rod to act on the corresponding fastening point of the optical module. In addition, this utility model is more convenient to operate.

[0022] (4) The present invention improves the ease of use by setting a handle extending outward from the base plate on the pressure rod, thereby making manual operation more labor-saving and enhancing the practicality of the present invention.

[0023] (5) This utility model provides a top block on the ends of the two arms of the clamping device that cooperates with the fastening point of the optical module, so that the assembly of the four-fastening point optical module sheet metal shell is more precise, thereby improving the assembly accuracy.

[0024] (6) This utility model further enhances the assembly accuracy by setting a front stop block that limits the front end of the optical module, a rear stop block that limits the rear end of the optical module, and side stops that are set on both sides of the optical module, and forming a guide structure on both sides of the optical module for use by the two arms of the clamping device.

[0025] (7) By providing a recessed groove in the side block wall and fixing one end of the reset spring in the groove and connecting the other end to the inner side of the clamping device bow, this utility model can limit the position of the clamping device when sliding towards the optical module. On the one hand, it can avoid the situation where the assembly is not in place due to the operator's lack of experience and needs to be reworked. On the other hand, it can also avoid damage to the optical module during the assembly process due to the operator's excessive force.

[0026] (8) By setting the groove perpendicular to the side wall of the optical module, this utility model can limit the extension and retraction path of the reset spring, avoid the situation where the reset spring is prone to breakage due to the tilt angle during extension and retraction, and extend the service life of the reset spring.

[0027] (9) This utility model provides a protrusion on the outer wall of the clamping device bow corresponding to the reset spring, which cooperates with the pressure rod. This can fix the pressure rod and the force point of the clamping device bow, avoid excessive friction between the clamping device and the base plate due to excessive lateral force applied by the pressure rod to the clamping device, and save time and effort, thereby improving assembly efficiency.

[0028] (10) By setting a limiting device for the opening and closing width of the pressure rod, this utility model avoids wasting assembly time due to the excessive distance between the two pressure rods, thereby improving assembly efficiency.

[0029] In summary, this utility model features a simple structure, low cost, and convenient operation. It not only achieves the goal of assembling the sheet metal shell of the four-button light module in one go, but also improves the accuracy and efficiency of assembly, meeting the fast-paced and high-quality production requirements of the production line. At the same time, it solves the problem in the prior art where the tilt angle of the reset spring during use causes easy breakage, shortened service life, and thus increased usage costs. It plays a role in improving quality and efficiency and has high practicality. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0038] Example 1:

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, this embodiment discloses an auxiliary device for assembling a sheet metal shell of a four-point optical module, including a base plate 1 with an optical module fixing part, two U-shaped clamping devices 5, and a pressure rod 2 that cooperates with the clamping devices 5. The two clamping devices 5 are respectively disposed on both sides of the optical module fixing part and are slidably connected to the optical module fixing part in the width direction. The two arms of the clamping devices 5 are respectively disposed corresponding to the two fastening points of the optical module on their respective sides. The pressure rod 2 is rotatably disposed on the base plate 1 and cooperates with the clamping device 5 on the same side.

[0040] In this embodiment, as Figures 1 to 3 As shown, the two arms of the two U-shaped clamping devices 5 correspond to the four fastening points of the optical module and are along the width direction of the optical module fixing part (i.e., the direction perpendicular to the side wall of the optical module). The two pressure rods 2 are rotatably set on the base plate 1 and are located on the outside of the two clamping devices 5 respectively.

[0041] In this embodiment, the two clamping devices 5 are slidably connected to the optical module fixing part by providing sliding grooves in the width direction of the optical module fixing part for the two arms of the two clamping devices 5 to slide. The sliding connection is prior art and will not be described in detail here.

[0042] In this embodiment, the rotatable connection between the pressure rod 2 and the base plate 1 is as follows: Figures 1 to 3 As shown, this is achieved by providing rotating shafts 6 on both sides of one end of the optical module fixing part, and sleeve one end of the pressure rod 2 on the rotating shaft 6; the other end of the pressure rod 2 extends to the other end of the optical module fixing part, and the ends of the two arms of the clamping device 5 rotate with the pressure rod 2 to act on the corresponding fastening points of the optical module, thereby realizing the one-time assembly function of the four-fastening point optical module sheet metal shell.

[0043] The working principle of this embodiment is as follows: by rotating the two pressure rods 2 inward, the two pressure rods 2 act on the bows of the two clamping devices 5 respectively. The ends of the two arms of the two clamping devices 5 rotate with the pressure rods 2 and act on the four fastening points of their corresponding optical modules respectively, thereby realizing the one-time assembly of the sheet metal shell of the four-fastening point optical module.

[0044] Before use, the initial state of this embodiment is as follows: Figure 1 and Figure 2 As shown, two clamping devices 5 are located on both sides of the optical module fixing part, and two pressure rods 2 are located outside the two clamping devices 5 and are in a relaxed state.

[0045] The operation steps of this embodiment are as follows:

[0046] Step 1: Place the optical module to be assembled into the optical module fixing part (e.g., Figures 1 to 2 (as shown)

[0047] Step 2: Rotate the two pressure rods 2 inward until... Figure 3 As shown, the two clamping devices 5 slide towards the optical module. The ends of the two arms of the two clamping devices 5 rotate with the pressure rod 2 and act on the four fastening points of their corresponding optical modules until the fastening points of the optical module's sheet metal shell are engaged.

[0048] Step 3: Rotate the pressure rod 2 outwards, then slide the two clamping devices 5 to the desired position. Figure 2 At the initial position shown, remove the assembled optical module;

[0049] Step 4: Continue to place the optical modules to be assembled, and repeat steps 1 to 3 above until all the optical modules to be assembled are completed.

[0050] Although this embodiment achieves one-time assembly of the sheet metal shell of the four-point optical module, it still has many shortcomings. In order to improve the convenience and practicality of this embodiment, a series of optimizations and improvements have been made to this embodiment.

[0051] Furthermore, such as Figures 1 to 3 As shown, in order to improve the accuracy of assembly and prevent unnecessary deformation of the optical module sheet metal shell during assembly, top blocks that cooperate with the fastening points of the optical module are provided at the ends of the two arms of the clamping device 5.

[0052] Furthermore, to enable the clamping device 5 to automatically reset and avoid manual operation, a return spring 7 connected to the base plate 1 is provided on the inner side of the bow portion of the clamping device 5, and the return spring 7 is perpendicular to the side wall of the optical module. This not only achieves the automatic reset function of the clamping device 5, but also ensures that the extension and retraction direction of the return spring 7 is consistent with the sliding direction of the clamping device 5, thereby preventing the return spring 7 from easily breaking due to tilting angle during use, and thus extending the service life of the return spring 7.

[0053] Regarding the setting of the reset spring 7, in this embodiment, the existing technology is adopted to open a groove on the side wall of the base plate 1, fix one end of the reset spring 7 in the groove, and connect the other end to the inner side of the bow of the clamping device 5.

[0054] Example 2:

[0055] like Figures 1 to 3 As shown, this embodiment discloses an auxiliary device for assembling a sheet metal shell for a four-point optical module, which is an optimized solution based on Embodiment 1. In this embodiment, the optical module fixing part includes a front stop 3 that limits the front end of the optical module, a rear stop 4 that limits the rear end of the optical module, and side stops 10 disposed on both sides of the optical module, forming guide structures on both sides of the optical module for use by the two arms of the two clamping devices 5 respectively.

[0056] In this embodiment, the front stop 3, the rear stop 4, and the two side stops 10 located on both sides of the optical module are used to limit the optical module and at the same time form a guide structure that limits the sliding direction of the two arms of the clamping device 5, thereby ensuring the accuracy of the fastening when the four-point optical module sheet metal shell is assembled.

[0057] In this embodiment, as Figure 4 and Figure 6 As shown, to limit the range of motion of the return spring 7 and prevent it from tilting and breaking during use, the outer wall of the side stop 10 in this embodiment is provided with an inwardly recessed feature. Figure 4 As shown in the groove 9, one end of the return spring 7 is fixed inside the groove 9, and the other end is connected to the inner side of the bow of the clamping device 5. In addition, since the side stop 10 is set on the inner side of the bow of the clamping device 5, it can also limit the stopping position of the clamping device 5 when it slides towards the optical module, which can effectively improve the assembly success rate of the four-point optical module sheet metal shell, thereby improving the assembly quality and efficiency.

[0058] Furthermore, to further enhance the accuracy of assembly, the groove 9 is perpendicular to the side wall of the optical module, thereby reducing the extension space of the return spring 7 and preventing it from tilting during extension and retraction.

[0059] Furthermore, to further enhance the accuracy during assembly, a protrusion that cooperates with the pressure rod 2 is provided on the outer wall of the clamping device 5 corresponding to the return spring 7. This allows the pressure rod 2 to directly act on the clamping device 5 through the protrusion when it rotates, avoiding excessive lateral force caused by the pressure rod 2 acting first on the arm of the clamping device 5 near the pressure rod 2, which would increase the friction between the clamping device 5 and the base plate 1 and thus save manpower.

[0060] Furthermore, to make manual assembly more labor-saving, such as Figures 1 to 3 As shown, a handle 8 extending outward from the base plate 1 is provided on the pressure rod 2. By squeezing the handle 8, the two pressure rods 2 are rotated inward, thereby causing the ends of the two arms of the two clamping devices 5 used in conjunction with them to act on the fastening points of the four optical modules, so as to achieve the purpose of assembling the sheet metal shell of the optical modules.

[0061] Furthermore, to improve device efficiency, a limiting device is provided on the pressure rod 2 to limit its opening and closing width. In this embodiment, the limiting device is a limiting ring fitted around the outside of both pressure rods 2, with the limiting ring fixedly connected to one of the pressure rods 2 and detachably fitted around the outside of the other pressure rod 2. In this embodiment, the limiting ring is a telescopic limiting ring, allowing its size to be adjusted as the pressure rods 2 open and close.

[0062] The working principle of this embodiment is as follows: by rotating the two pressure rods 2 inward, the pressure rods 2 act on the bow of the corresponding clamping device 5, and push the clamping device 5 guide structure to slide in the guiding direction (i.e. the width direction of the optical module fixing part) and act on the four fastening points of the optical module corresponding to the two arms of the two clamping devices 5, thereby realizing the one-time assembly of the four-fastening point optical module sheet metal shell.

[0063] The operation steps of this practical example (taking manual operation as an example):

[0064] Step 1: Place the optical module to be assembled into the optical module fixing part, with the front end of the optical module positioned at the location defined by the front stop 3 and the rear end of the optical module positioned at the location defined by the rear stop 4 (e.g., Figures 1 to 2 (as shown)

[0065] Step 2: Pinch the two levers 2 tightly (as shown) Figure 3 As shown), the four ends of the two arms of the two clamping devices 5 rotate with the pressure rod 2 and act simultaneously on the four fastening points of their corresponding optical modules until the fastening points of the optical module sheet metal shell are squeezed and the fastening is completed.

[0066] Step 3: Release the pressure rod 2, and the two clamping devices 5 will reset under the action of the return spring 7 (i.e., return to the original position). Figure 2 (as shown in the image), then remove the assembled optical module;

[0067] Step 4: Continue to place the optical modules to be assembled, and repeat steps 1 to 3 above until all the optical modules to be assembled are completed.

[0068] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
