Description

Technical Field

[0001] The invention relates to the field of optical communication, and in particular to a TO-CAN packaging centering device. Background Art

[0002] With the development of the optical communication industry, the commonly used transmitter optical subassembly (TOSA) and receiver optical subassembly (ROSA) have formed a relatively standardized package - TO-CAN package, which is shaped like a cylindrical can and consists of a shell cap and a shell seat. The shell cap is a cylindrical shell hollowed out from one side, and the other side may have a light outlet or a lens (need to be airtight) according to actual needs; the shell seat is usually a cylindrical piece, and there will be PIN needles on the circular surface according to actual needs (need to be airtight through the circular surface), and usually optical chips, devices, etc. are also made on the shell seat; the shell cap and the shell seat are integrated by gluing or welding.

[0003] In order to ensure that the optical axis of the light-emitting / light-receiving device on the shell base can coincide with the optical axis of the light-emitting lens on the shell cap, it is necessary to ensure the coaxiality of the shell cap and the shell base (the coaxiality requirement may be achieved with an eccentricity not exceeding 20 to 45um). The outer circle of the shell base and the positioning outer circle of the shell cap have tolerances. Sometimes these external dimension tolerances will exceed the allowable eccentricity, which poses a challenge to the equipment / device that ensures the concentricity of the shell base / shell cap.

[0004] Currently, two clamps installed on a high-precision electric-controlled linear guide are used to clamp the outer circle of the shell seat from both sides; a vacuum suction nozzle that is slightly larger than the outer circle of the shell cap positioning is used to achieve relative positioning using vacuum (vacuum self-centering cannot guarantee that it will be in the same position every time), and the nominal position of the center is gradually found through pressure test adjustment.

[0005] Existing solutions require the use of expensive guide rail components and control systems, which involve complex structures. Therefore, each equipment supplier usually has its own solution for this centering device. If you want to use it, you must purchase expensive equipment. For equipment that does not have self-centering accessories, you also need to buy expensive equipment upgrade packages from the equipment supplier. For shell seats / shell caps of different dimensions, corresponding matching centering devices are required. A single set of centering devices has poor applicability and high cost. Summary of the invention

[0030] Now, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0031] like Figures 1 to 7 As shown, the present invention provides a preferred embodiment of a TO-CAN package centering device.

[0032] A TO-CAN package centering device comprises a positioning portion 10 for positioning one of a shell cap and a shell seat of a device to be packaged; a base 20 provided with a through hole 21, wherein the through hole 21 corresponds to the position of the positioning portion 10; a clamping assembly 30 arranged on the base 20, wherein the clamping assembly 30 comprises a first clamping mechanism 31 and a second clamping mechanism 32 for positioning the other of the shell cap and the shell seat, wherein the first clamping mechanism 31 and the second clamping mechanism 32 can both move closer to or away from the axis of the positioning portion 10.

[0033] By providing a positioning portion 10, a base 20 with a through hole 21, and a clamping assembly 30 arranged on the base 20, the through hole 21 corresponds to the position of the positioning portion 10, the positioning portion 10 positions one of the shell cap and the shell seat of the packaged device, the first clamping mechanism 31 and the second clamping mechanism 32 of the clamping assembly 30 can move close to or away from the axis of the positioning portion 10, and position the other of the shell cap and the shell seat of the packaged device, so as to realize adaptive positioning and centering of the shell seat and the shell cap of different outer sizes in the packaged device, the operation is fast and convenient, the applicability is strong, the structure is simple, and the cost is low.

[0034] Among them, in this embodiment, the positioning part 10 is preferably used to position the shell cap of the device to be packaged, and the first clamping mechanism 31 and the second clamping mechanism 32 of the clamping assembly 30 can move close to or away from the axis of the positioning part 10 to clamp and position the shell seat of the device to be packaged. The axis of the positioning part 10 coincides with the axis of the shell cap, and the first clamping mechanism 31 and the second clamping mechanism 32 are close to the axis of the positioning part 10 to position the shell seat of the device to be packaged. The axis of the shell seat also coincides with the axis of the positioning part 10, and then the axis of the shell seat coincides with the axis of the shell cap, so that the shell seat and the shell cap are positioned and aligned.

[0035] Furthermore, the base 20 can be made of a high-strength, dimensionally stable material.

[0036] In this embodiment, reference Figures 1 to 5 The first clamping mechanism 31 includes a first clamping member 311 and a first elastic member 312 arranged between the base 20 and the first clamping member 311. The first clamping member 311 moves close to the axis of the positioning portion 10 under the elastic force of the first elastic member 312, and compresses the first elastic member 312 to move away from the axis of the positioning portion 10.

[0037] Furthermore, the second clamping mechanism 32 includes a second clamping member 321 and a second elastic member 322 arranged between the base 20 and the second clamping member 321. The second clamping member 321 moves close to the axis of the positioning portion 10 under the elastic force of the second elastic member 322, and compresses the second elastic member 322 to move away from the axis of the positioning portion 10.

[0038] During the entire process of clamping and positioning the shell cap and the shell seat, the first elastic member 312 and the second elastic member 322 are both in a compressed state. The first elastic member 312 is compressed, providing the first clamping member 311 with a force to move close to the axis of the positioning portion 10 to clamp the positioning shell seat; the second elastic member 322 is compressed, providing the second clamping member 321 with a force to move close to the axis of the positioning portion 10 to clamp the positioning shell seat.

[0039] Specifically, the first elastic member 312 and the second elastic member 322 are preferably springs. In other embodiments, the first elastic member 312 and the second elastic member 322 can be elastic members made of elastic materials. And the first clamping member 311 and the second clamping member 321 can be made of high-strength, dimensionally stable materials.

[0040] Further, the end of the first clamping member 311 away from the first elastic member 312 is provided with a first positioning arc 3111, and the end of the second clamping member 321 away from the second elastic member 322 is provided with a second positioning arc 3211, and the first clamping member 311 and the second clamping member 321 move close to the axis of the positioning portion 10 so that the first positioning arc 3111 and the second positioning arc 3211 enclose the other of the positioning shell cap and the shell seat. The provision of the first positioning arc 3111 and the second positioning arc 3211 enables the first clamping member 311 and the second clamping member 321 to fit the other of the positioning shell cap and the shell seat more closely when they move close to the axis of the positioning portion 10 for clamping, and the clamping positioning is more stable.

[0041] Furthermore, a lockable knob 314 may be provided on the first clamping member 311 and the second clamping member 321 , respectively, and an operator may operate the lockable knob 314 to pull the first clamping member 311 and the second clamping member 321 away from the axis of the positioning portion 10 .

[0042] In this embodiment, the base 20 is provided with a first slide groove 22 and a second slide groove 23 arranged along the moving direction of the first clamping member 311, the first clamping mechanism 31 also includes a first slider 313 connected to the first clamping member 311 and adapted to the first slide groove 22, and the second clamping mechanism 32 also includes a second slider 323 connected to the second clamping member 321 and adapted to the second slide groove 23. The first slide groove 22 is arranged along the moving direction of the first clamping member 311. During the movement of the first clamping member 311, the first slider 313 adapted to the first slide groove 22 moves along the first slide groove 22, so that the first clamping member 311 maintains stable movement, prevents the first clamping member 311 from deviating, and improves the accuracy of subsequent positioning and centering. The second slide groove 23 and the second slider 323 play the same role on the first clamping member 311.

[0043] Furthermore, the base 20 is further provided with a first guide rail 24 and a second guide rail 25, the first clamping member 311 is slidably disposed on the base 20 via the first guide rail 24, and the second clamping member 321 is slidably disposed on the base 20 via the second guide rail 25. The first guide rail 24 guides the movement of the first clamping member 311, and the second guide rail 25 guides the movement of the second clamping member 321.

[0044] Specifically, refer to Figure 6 Two first guide rails 24 and two second guide rails 25 are arranged in the base 20, a first slide groove 22 is formed between the two first guide rails 24, and a second slide groove 23 is formed between the two second guide rails 25.

[0045] In this embodiment, the TO-CAN package centering device further includes a first stopper 40 and a second stopper 50 disposed on the base 20, wherein the first stopper 40 abuts against the first clamping member 311 when the first clamping member 311 moves close to the axis of the positioning portion 10, and the second stopper 50 abuts against the second clamping member 321 when the second clamping member 321 moves close to the axis of the positioning portion 10. The first clamping member 311 is provided with a first stopper 3112 abutting against the first stopper 40 when the first clamping member 311 moves close to the axis of the positioning portion 10, and the second clamping member 321 is provided with a second stopper 3212 abutting against the second stopper 50 when the second clamping member 321 moves close to the axis of the positioning portion 10. The provision of the first stopper 40 and the second stopper 50 enables the first clamping member 311 and the second clamping member 321 to clamp the positioning shell cap or shell seat with appropriate force.

[0046] The first stopper 40 and the second stopper 50 are both provided with a strip hole 41 arranged along the moving direction of the first clamping member 311, and the TO-CAN package centering device also includes a screw penetrating the strip hole 41 to lock the first stopper 40 and the second stopper 50 on the base 20, and the first stopper 40 and the second stopper 50 can adjust their positions on the base 20 along the moving direction of the first clamping member 311 through the strip hole 41 and the screw. The operator can adjust the positions of the first stopper 40 and the second stopper 50 on the base 20, and fix the first stopper 40 and the second stopper 50 on the base 20 through the strip hole 41, so as to adapt to the clamping and positioning of shell caps or shell seats with different external dimensions.

[0047] In this embodiment, the positioning portion 10 includes a positioning seat 11 having a positioning hole 111, and the TO-CAN package centering device also includes a first isolating member 60 disposed between the first clamping member 311 and the positioning seat 11, and a second isolating member 70 disposed between the second clamping member 321 and the positioning seat 11. The positioning hole 111 is used to place the shell cap and position the shell cap. At this time, the axis of the positioning hole 111 is the axis of the positioning portion 10.

[0048] Specifically, refer to Figure 3 , Figure 5 and Figure 7 The first clamping member 311 is provided with a first strip groove 3113, the second clamping member 321 is provided with a second strip groove 3213, the first isolating member 60 is provided with a first boss 61 clamped in the first strip groove 3113, and the second isolating member 70 is provided with a second boss 61 clamped in the second strip groove 3213. When the first clamping member 311 moves, the first boss 61 moves in the first strip groove 3113; when the second clamping member 321 moves, the second boss 61 moves in the second strip groove 3213.

[0049] The positioning seat 11 may be a lower electrode with a conductive function. When the first clamping member 311 and the second clamping member 321 are made of conductive materials, the first isolating member 60 and the first boss 61 may prevent the first clamping member 311 from deforming and contacting the lower electrode to form a loop; the second isolating member 70 and the second boss 61 may prevent the second clamping member 321 from deforming and contacting the lower electrode to form a loop.

[0050] In this embodiment, the TO-CAN package centering device further includes a calibration member 80 for calibrating the positioning shell cap and the shell seat.

[0051] Specifically, refer to Figure 1 , 2 and Figure 8The proofreading part 80 includes a counterweight 81, a first cylinder 82 whose cross-sectional diameter corresponds to the outer diameter of the shell cap, and a second cylinder 83 whose two ends are respectively connected to the counterweight 81 and the first cylinder 82 and whose cross-sectional diameter corresponds to the outer diameter of the shell seat. The counterweight 81 is used to maintain the balance of the entire proofreading part 80. When the proofreading part 80 is used to calibrate the positioning shell cap and the shell seat, the first cylinder 82 is inserted into the positioning hole 111 of the positioning seat 11, and the cylindrical surface of the first cylinder 82 is correspondingly pressed against the inner wall of the positioning hole 111; under the elastic force of the first elastic member 312 and the second elastic member 322, the first clamping member 311 and the second clamping member 321 move close to the axis of the positioning portion 10, and the first positioning arc 3111 and the second positioning arc 3211 are both pressed against the outer circumference of the second cylinder 83, and the first clamping member 311 and the second clamping member 321 clamp the positioning portion 10. The second cylindrical body 83 is positioned. At this time, the first clamping member 311 can be locked on the first guide rail 24 by means of a locking screw, the second clamping member 321 can be locked on the second guide rail 25, the first limiting member 40 can be pressed against the second limiting portion 3212 of the first clamping member 311, and the second limiting member 50 can be correspondingly locked on the base 20 through the strip hole 41 using a screw, the second limiting member 50 can be pressed against the second limiting portion 3212 of the second clamping member 321, and the second limiting member 50 can be correspondingly locked on the base 20 through the strip hole 41 using a screw, and the calibration is completed. During the calibration process, the end face of the second cylindrical body 83 connected to the first cylindrical body 82 always keeps in contact with the end face of the positioning seat 11.

[0052] The sizes of the first cylinder 82 and the second cylinder 83 of the proofreading member 80 can be set according to the actual shell cap and shell seat of the sealing cap. For example, if the outer diameter of the shell cap is x+ / -a, the diameter of the corresponding first cylinder 82 can be set to correspond to the maximum range of the outer diameter of the shell cap, that is, x+a.

[0053] Furthermore, for products of different batches (shell caps and shell seats), operators can screen the products and divide them into multiple grades, so that the tolerance zone can be reduced. For each grade, a proofreading part 80 is made. Correspondingly, the operator can set a positioning seat 11 with positioning holes 111 of different sizes for different grades, thereby reducing the influence of the product outer circle tolerance on the centering accuracy and further improving the centering accuracy.

[0054] In this embodiment, the TO-CAN package centering device may also include an upper electrode 90 corresponding to the lower electrode, and the upper electrode 90 is provided with an avoidance hole 91 for avoiding the pins on the empty shell seat when the device is packaged. An insulating ring 100 may also be arranged between the lower electrode and the base 20 to prevent the formation of an electrical circuit passing through the shell cap and the shell seat. After the centering operation of the shell cap and the shell seat is completed, the upper electrode 90 is pressed down so that the upper electrode 90 contacts the lower electrode. The TO-CAN package centering device is installed on an external capping machine, and the welding packaging operation is performed after power is turned on. Among them, the upper electrode 90 is installed on the capping base of the upper electrode 90 of the external capping machine, and the lower electrode is installed on the capping base of the lower electrode of the external capping machine. The upper electrode 90 and the lower electrode are usually made of good conductors such as copper.

[0055] During the welding packaging process, the upper electrode 90 and the lower electrode pressurize the shell cap and the shell seat so that the two form a certain contact resistance under the pressure of the upper electrode 90 and the lower electrode, and when the welding current flows from one electrode through the other electrode, instantaneous hot melt heat is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the shell cap and the shell seat to this electrode to form a loop without damaging the internal structure of the workpiece being welded.

[0056] The working principle of the TO-CAN package centering device in this embodiment is as follows:

[0057] When loading, the operator can pull open the first clamp 311 through the lockable knob 314, compress the spring, and move the first clamp 311 away from the axis of the positioning hole 111 through the first guide rail 24, place the shell cap in the positioning hole 111 of the lower electrode, position the shell cap, and then put the shell seat on; release the lockable knob 314, and the first clamp 311 moves close to the axis of the positioning hole 111 under the elastic force of the spring, and clamps the positioning shell seat together with the second clamp 321 to complete the positioning and centering operation of the shell cap and the shell seat. When unloading, the operator can pull open the first clamp 311 through the lockable knob 314, and take out the shell cap and shell seat that have completed the welding package. Of course, the second clamp 321 can also be operated to perform the above operation.

[0058] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
