Description

[Technical Field]

[0001] This utility model belongs to the field of pump source assembly technology, and in particular relates to a general-purpose COS assembly equipment. [Background Technology]

[0002] Currently, semiconductor pump source packaging structures mainly consist of several arrays of optical modules composed of COS modules, fast-axis collimating lenses (FAC), slow-axis collimating lenses (SAC), and reflectors. These optical modules are all mounted on a metal or ceramic base. For example, Chinese Patent Publication No. CN115296139B describes a COS assembly method and equipment based on a modular base. Individual solder pieces and individual COS products are sequentially positioned onto the modular insulating bases of a clamping fixture. After solder pieces and COS products are assembled on several modular insulating bases of the clamping fixture, the entire clamping fixture carrying the modular insulating bases and COS modules can be directly removed and placed into subsequent welding equipment for welding. During the transfer process, the position of the COS modules does not shift, improving welding accuracy. However, this solution still has the following problems:

[0003] (1) A clamping fixture is provided, which is provided with several bearing grooves for supporting modular insulating bases. Each bearing groove is provided with a first clamping component for clamping the COS module in the modular insulating base. The first clamping component includes a lifting rod that is movably mounted on a support base. The lifting rod is located on the outer side of the end of the bearing groove and its top extends towards the space above the bearing groove to form a horizontal support part. A clamping component for clamping the COS module is provided on the horizontal support part. This solution can achieve the clamping of the COS module. However, the size of the bearing groove for supporting the modular insulating base in this solution is fixed. It can only be used for modular insulating bases of fixed size and cannot be used for modular insulating bases of other sizes. For pump sources of different sizes, there will be pump source insulating bases of different sizes. Therefore, there will be modular insulating bases of different sizes. Multiple clamping fixtures need to be equipped, and the replacement cost is high.

[0004] (2) The first CCD camera set in this scheme is only to obtain the position of the COS module and solder sheet at the feeding point, as well as the assembly position on the modular insulating base. Since the solder sheet is very thin, it is easy to shift during the adsorption and handling process. Even if the first CCD camera can obtain the assembly position, the solder sheet after the shift will also have the problem of assembly shift, which will affect the welding accuracy of the subsequent welding and reduce the welding yield.

[0005] (3) The solder sheet adopts the method of feeding the material roll, including the unwinding module, the strip winding module, and the cover winding module. All of them adopt the method of ring-shaped material roll and are located on the processing plane. The layout is unreasonable and occupies a lot of space.

[0006] Therefore, it is necessary to provide a universal COS assembly device to solve the above-mentioned technical problems. [Utility Model Content]

[0007] The main purpose of this utility model is to provide a universal COS assembly equipment, which can not only position insulating bases of different sizes, but also press different numbers of COS modules on the insulating bases, making it more versatile; the assembly equipment not only has a simpler structure, but also improves the assembly accuracy.

[0019] Furthermore, the solder sheet feeding mechanism includes a strip conveyor line located on the frame, an unwinding module and a strip discharge pipe disposed at both ends of the strip conveyor line, a cover winding module located on one side of the unwinding module, and a third CCD camera located above the strip conveyor line. The unwinding module is disposed at the bottom of the frame.

[0020] Furthermore, the COS feeding module includes a tray positioning carrier and a feeding frame for positioning the tray positioning carrier. The tray positioning carrier is provided with a plurality of positioning grooves for positioning the tray. A plurality of pressing plates for pressing the tray are provided on the top of the opposite sides of the positioning grooves. An elastic supporting member is provided on one side of the positioning groove and is supported on the side of the tray. The positioning groove has three surrounding barriers.

[0024] Furthermore, the CCD camera module includes a first motor mounted on the first support plate, a third mounting plate driven by the first motor to move up and down, and a second CCD camera mounted on the third mounting plate.

The push rod extends horizontally and acts on the lifting rod.

[0026] Compared with the prior art, the beneficial effects of this utility model's universal COS assembly equipment are as follows:

[0027] (1) The clamping fixture body is provided with several positioning holes and threaded holes. Selectively, a first positioning pin is provided in some of the positioning holes and / or a first screw is provided in some of the threaded holes to achieve positioning of insulating bases of different sizes, which is more versatile.

According to the length of the insulating base, several corresponding clamping modules can be selectively installed on the mounting beam.

Therefore, this solution can not only achieve positioning of insulating bases of different sizes, but also clamp different numbers of COS modules on the insulating base, which is more versatile.

[0028] (2) The first CCD camera can take pictures to confirm the position of the COS module and the solder sheet. If the angle of the solder sheet is offset, the rotation drive will drive the adsorption rod to rotate according to the picture result, and the position of the solder sheet will be compensated to correct the position of the solder sheet, which can improve the assembly accuracy. If the position of the COS module is offset, the second CCD camera will take pictures to confirm the position of the COS module in real time during the subsequent assembly of the COS module. The three-axis transfer module will adjust the position of the COS module in real time to ensure the accuracy of the COS module assembly. Therefore, this solution is equipped with multiple CCD cameras to take pictures for confirmation, which can further improve the assembly accuracy and thus improve the product quality.

[0029] (3) The unwinding module is set at the bottom of the frame, which can reduce the area occupied by the solder sheet feeding mechanism on the working surface and save space; the material strip discharge pipe can directly discharge the empty material strip through the material strip to the assembly equipment. Compared with the existing technology of using a reel to collect empty material strip, the material strip discharge pipe is not only simple in structure, but also saves space, thereby simplifying the structure of the assembly equipment.

Detailed Implementation Methods

[0053] Please refer to Figures 1-11 This embodiment is a general-purpose COS assembly device 100, which includes:

[0054] At least one clamping fixture 1 is set on the assembly station 10. The clamping fixture 1 is provided with a fixture body 11 for positioning the insulating base 200. Several clamping modules 12 for clamping the COS module 300 are provided above the fixture body 11. Several positioning holes 13 and several threaded holes 14 are provided on the fixture body 11. First positioning pins are selectively provided in some of the positioning holes 13 and / or first screws are selectively provided in some of the threaded holes 14 to achieve positioning of insulating bases 200 of different sizes. The number of clamping modules 12 is increased or decreased to achieve clamping of different numbers of COS modules 300 on the insulating base 200.

[0055] Solder sheet feeding mechanism 2 is used for automatic feeding of solder sheet 400. A first CCD camera 7 is provided on the side of solder sheet feeding mechanism 2.

[0056] COS feeding module 3 is used for automatic feeding of COS module 300;

[0057] Solder sheet adsorption and handling mechanism 4 is used to adsorb and handle solder sheet 400 and place it in the assembly slot of insulating base 200;

[0058] COS clamping and transporting mechanism 5 is used to clamp and transport COS module 300 and place it on solder sheet 400;

[0059] The solder sheet adsorption and handling mechanism 4 and the COS clamping and handling mechanism 5 are jointly mounted on a three-axis transfer module 6, and a CCD camera module 8 is also mounted on the three-axis transfer module 6.

[0060] The clamping module 9, which is set on the assembly station 10, is used to open the clamping module 12 above the assembly groove inside the insulating base 200 on the clamping fixture 1.

[0061] The fixture body 11 is provided with a plurality of positioning holes 13 and a plurality of threaded holes 14. First positioning pins are selectively provided in some of the positioning holes 13 and / or first screws are selectively provided in some of the threaded holes 14 to achieve positioning of insulating bases 200 of different sizes, thus increasing versatility. Specifically, when the insulating base 200 is positioned on the fixture body 11, any of the following positioning methods can be selected according to the structure and size of the insulating base 200:

[0062] The first positioning method: selectively setting the first positioning pin in some positioning holes 13 to achieve positioning of the insulating base 200;

[0063] The second positioning method: selectively setting the first screw in part of the threaded hole 14 to achieve positioning of the insulating base 200;

[0064] The third positioning method: selectively setting a first positioning pin in some positioning holes 13 and selectively setting a first screw in some threaded holes 14 together to achieve positioning of the insulating base 200.

[0065] Because the structure and size of the insulating base 200 are different, the first positioning pin can be selectively set in the positioning hole 13 at different positions, and the first screw can also be selectively set in the threaded hole 14 at different positions. Therefore, each of the above positioning methods has multiple positioning methods. The positions of the first positioning pin and the first screw are adjusted adaptively according to the different structure and size of the insulating base 200, which is not limited here.

[0066] Assembly station 10 is equipped with at least one workbench 101. A clamping fixture 1 is positioned on the workbench 101. The fixture body 11 has several guide holes 17 for guiding and positioning, facilitating the positioning of the clamping fixture 1 onto the workbench 101. Several suction blocks 18 are provided on the back of the fixture body 11. The workbench 101 is equipped with second positioning pins that mate with the guide holes 17 and electromagnets that mate with the suction blocks 18 for suction and positioning. When the electromagnets are energized, they attract the suction blocks 18, thus achieving suction and fixation between the workbench 101 and the clamping fixture 1. The guide holes 17 and suction blocks 18 ensure stable positioning of the clamping fixture 1 on the workbench 101. One end of the fixture body 11 has a mistake-proof notch 19, which prevents incorrect use (using the fixture on the wrong side). A first sensor 104 for detecting the mistake-proof notch 19 is correspondingly provided on the workbench 101.

[0067] In this embodiment, to improve work efficiency, two workbenches 101 are provided, each equipped with a clamping fixture 1. Two clamping fixtures 1 can be placed onto the two workbenches 101 at once, reducing the frequency of placing and removing the clamping fixtures 1. In other embodiments, the number of workbenches 101 and clamping fixtures 1 can be set according to actual conditions. Alternatively, only one workbench may be provided, but this workbench may have several slots for mounting the clamping fixtures 1. These can be set according to actual conditions and are not limited here.

[0068] In this embodiment, since several COS modules 300 need to be assembled on both the front and rear sides of the insulating base 200, two rows of clamping modules 12 are arranged correspondingly on the front and rear of the clamping fixture 1 to clamp the front and rear COS modules 300 respectively. The clamping fixture 1 has two horizontally arranged, parallel mounting beams 15 above the fixture body 11, with a clearance space 16 between the two mounting beams 15. Several clamping modules 12 are arranged linearly on both mounting beams 15. The clamping modules 12 on the front and rear mounting beams 15 respectively clamp the front and rear sides of the insulating base 200, achieving bilateral clamping, which improves stability during clamping and ensures welding accuracy.

[0069] In other embodiments, the number of mounting beams 15 can be increased, or the arrangement of the clamping modules 12 can be changed to achieve three-sided clamping, four-sided clamping, or multi-sided clamping of the insulating base 200, thereby improving the stability of clamping and further ensuring the accuracy of COS module welding.

[0070] The clamping module 12 includes a lifting rod 121 movably mounted on the mounting beam 15, a limiting block 122 mounted on the upper end of the lifting rod 121 and restricted to the upper surface of the mounting beam 15, a holding member 123 mounted on the lower end of the lifting rod 121 and pressed against the surface of the COS module 300, and an elastic member 124 mounted on the lifting rod 121 and causing the holding member 123 to elastically press against the COS module. In this embodiment, the holding member 123 is a pin, and the elastic member 124 is a vertically extending spring. In other embodiments, the holding member 123 may be configured as other clamping structures, and the elastic member 124 may be configured as other elastic structures, which are not limited here.

[0071] The limiting block 122 is fixed to the upper end of the lifting rod 121 by the second screw 126, and the pressing member 123 is set at the lower end of the lifting rod 121 by the spring piece 125.

[0072] The lifting rod 121 includes a first lifting part 1211 with its upper end vertically arranged and movable up and down on the mounting beam 15, a second lifting part 1212 with its lower end vertically arranged and on which the holding member 123 is installed, and a connecting part 1213 that connects the first lifting part 1211 and the second lifting part 1212 and is in a horizontal state.

[0073] The spring piece 125 is fixedly mounted on the connecting part 1213. One end of the spring piece 125 extends out of the outer side of the connecting part 1213 and is provided with a plurality of first mounting holes for mounting the clamping member 123. The upper end of each clamping member 123 is fixed in the corresponding first mounting hole. In this embodiment, two clamping members 123 are arranged relatively parallel on each spring piece 125 and pressed against the COS module 300. The clamping is on both sides of the COS module 300, which can ensure the stability during clamping. In other embodiments, the number of clamping members 123 provided on each spring piece 125 is determined according to the actual situation and is not limited here.

[0074] The second lifting part 1212 is provided with a second mounting hole 1214 for mounting the holding member 123 and a guide limiting hole 1215 for guiding and limiting the holding member 123. The upper end of the holding member 123 is fixed on the first mounting hole, extends downward through the guide limiting hole 1215, and the lower end is fixed on the second mounting hole 1214. The connecting part 1213 is provided with a vertically extending guide rod 1216. An elastic member 124 is sleeved on the outer periphery of the guide rod 1216. The spring piece 125 and the connecting part 1213 are each provided with a third mounting hole for mounting the guide rod 1216.

[0075] The mounting beam 15 is provided with a number of through holes 151 that are similar to the first lifting part 1211 and a number of stepped holes 152 for mounting the elastic element 124 along its length. The through holes 151 and the stepped holes 152 are arranged in pairs. The lower end of the elastic element 124 abuts against the spring piece 125 and the upper end abuts against the wall of the stepped hole 152. The elastic element 124 is locked in the stepped hole 152 of the mounting beam 15. When the lifting rod 121 rises, the elastic element 124 is compressed. Since the mounting beam 15 has several pairs of contoured through holes 151 and stepped holes 152 along its length, several corresponding clamping modules 12 can be selectively installed on the mounting beam 15 according to the length of the insulating base 200. Therefore, the number of clamping modules 12 can be increased or decreased so that the arrangement of the clamping modules 12 corresponds to the number of assembly slots on the insulating base 200, so as to achieve clamping of different numbers of COS modules 300 in the insulating base 200, which is more versatile.

[0076] The principle of positioning the insulating base 200 using the clamping fixture 1 is as follows: When the clamping fixture 1 is not clamping the insulating base 200 in its initial state, the limiting block 122 is restricted to the upper surface of the mounting beam 15. When it is necessary to clamp the insulating base 200, the external mechanism (not shown in the figure) drives several lifting rods 121 to move upward, thereby simultaneously lifting several holding members 123 upward, so that the vertical gap can accommodate the insulating base 200, thus placing the insulating base 200 onto the fixture body 11. At this time, the elastic member 124 is compressed. After the insulating base 200 is placed, selective positioning holes are used in some areas. The insulating base 200 is positioned by a first positioning pin and / or a first screw selectively provided in a portion of the threaded hole 14. The driving force of the external mechanism (not shown in the figure) is removed, and the elastic element 124 extends to move the lifting rod 121 downward, thereby pressing the holding member 123 into the assembly slot of the COS module 300 to be installed on the insulating base 200. The holding member 123 can be elastically pressed by the elastic element 124, and can be adaptively expanded according to the different flatness of the product surface, so as to adapt to the assembly slots of different heights and have good versatility.

[0077] In this embodiment, the solder sheet 400 is fed using a reel-type feeding system, with the solder sheet placed independently in the feed trough of the feed strip in a reel shape. In this embodiment, the solder sheet feeding mechanism 2 includes a feed strip conveyor line 21 located on the frame 80, an unwinding module 22 and a feed strip discharge pipe 23 located at both ends of the feed strip conveyor line 21, a cover winding module 24 located on one side of the unwinding module 22, and a third CCD camera 25 located above the feed strip conveyor line 21. The unwinding module 22 provides a complete roll of material strip. To save space, the unwinding module 22 is located at the bottom of the frame 80, which has clearance through holes 801 for conveying the material strip. The material strip conveyor line 21 is used to convey the unwound material strip forward at equal intervals. The material strip discharge pipe 23 is used to discharge empty material strip. The empty material strip is directly discharged from the assembly equipment through the material strip discharge pipe 23. Compared with the existing technology of collecting empty material strip by means of a reel, the material strip discharge pipe 23 can save space and simplify the structure of the assembly equipment. The material cover rewinding module 24 is used to rewind the material cover that is closed on the material strip. The material cover can be a plastic part or a film. The second CCD camera 25 is used to inspect the appearance quality of the solder sheet.

[0078] The COS feeding module 3 adopts a tray-type feeding system. The COS feeding module 3 includes a tray positioning carrier 31 and a feeding rack 32 for positioning the tray positioning carrier 31. The tray positioning carrier 31 is provided with several positioning grooves 311 for positioning the tray 500. Several pressing plates 312 for pressing the tray 500 are provided on the top of the opposite sides of the positioning grooves 311. An elastic pressing member 313 is provided on one side of the positioning groove 311 and presses against the side of the tray 500. The positioning groove 311 has three surrounding barriers. The tray 500 is pushed into the positioning groove 311 from one side in a drawer-like manner. The three-axis barriers position the tray 500 in three axes. At the same time, the pressing plates 312 press the surface of the tray 500, restricting the vertical freedom of the tray 500 and keeping it in a fixed position. The elastic pressing member 313, in conjunction with the three surrounding barriers, restricts the lateral freedom of the tray 500 and keeps it in a fixed position. The feeding rack 32 is provided with a third positioning pin 321 for the positioning tray positioning carrier 31 and a second sensor 322 for detecting whether the positioning tray positioning carrier 31 is in place. The positioning tray positioning carrier 31 is provided with a second mating hole 314 that cooperates with the third positioning pin 321 and an avoidance opening 315 for the detection light of the second sensor 322 to pass through.

[0079] In this embodiment, two COS feeding modules 3 are arranged side by side, each with six trays, for a total of twelve trays, which reduces the feeding frequency of tray 500. In other embodiments, the number of COS feeding modules 3 can be set according to actual needs, and the number of trays on each COS feeding module 3 is not limited; it can be set according to actual needs.

[0080] The three-axis transfer module 6 includes a first linear drive 61, a crossbeam 62 driven by the first linear drive 61 to move back and forth, a second linear drive 63 disposed on the crossbeam 62, a first support plate 64 driven by the second linear drive 63 to move left and right, a third linear drive 65 disposed on the first support plate 64, and a second support plate 66 driven by the third linear drive 65 to move up and down.

[0081] The solder sheet adsorption and transport mechanism 4 includes a first cylinder 41 mounted on a second support plate 66, a first mounting plate 42 driven by the first cylinder 41 to move up and down, a rotary drive 43 mounted on the first mounting plate 42, and an adsorption rod 44 driven by the rotary drive 43 to rotate around a vertical axis. The bottom of the adsorption rod 44 is provided with an adsorption hole for adsorbing solder sheets.

[0082] The COS clamping and handling mechanism 5 includes a second cylinder 51 mounted on a second support plate 66, a second mounting plate 52 driven by the second cylinder 51 to move up and down, an electric cylinder 53 mounted on the second mounting plate 52, and a pair of grippers 54 driven by the electric cylinder 53 to perform opening or clamping actions. The grippers 54 are controlled by the electric cylinder 53, which has good stability and can improve the clamping accuracy.

[0083] Both the adsorption rod 44 and the gripper 54 are slender structures. The adsorption rod 44 extends vertically and the gripper 54 extends obliquely. Both the adsorption rod 44 and the gripper 55 can extend into the insulating base 200 through the clearance space 16 set between the two mounting beams 15. The adsorption rod 44 first assembles the solder sheet 400 onto the insulating base 200, and then the gripper 54 assembles the COS module 300 onto the solder sheet 400.

[0084] The CCD camera module 8 is mounted on the first support plate 64 and is used to photograph and confirm the COS module 300 and the solder sheet 400. The CCD camera module 8 includes a first motor 81 mounted on the first support plate 64, a third mounting plate 82 driven by the first motor 81 to move up and down, and a second CCD camera 83 mounted on the third mounting plate 82. The first motor 81 can drive the second CCD camera 83 to move up and down, enabling it to photograph COS modules 300 or insulating bases 200 at different heights, thus providing good versatility.

[0085] The first CCD camera 7 is located behind the material conveyor line 21. The first CCD camera 7 takes pictures of the clamped COS module 300 and the adsorbed solder sheet 400 for confirmation. Specifically, after the adsorption rod 44 adsorbs the solder sheet 400, it moves above the first CCD camera 7 to take pictures of the position of the solder sheet 400 for confirmation. If the angle of the solder sheet 400 is offset, the rotation drive 43 drives the adsorption rod 44 to rotate according to the picture result, and performs angle compensation on the position of the solder sheet 400 to correct the position of the solder sheet 400, which can improve the assembly accuracy. If the position of the COS module 300 is offset, the second CCD camera 83 will take pictures of the COS module in real time to confirm the position during the subsequent assembly of the COS module 300. The three-axis transfer module 6 adjusts the position of the COS module in real time to ensure the accuracy of the COS module assembly. A waste collection box 70 is also provided next to the first CCD camera 7. If the first CCD camera 7 or the second camera 83 confirms that the solder sheet 400 or COS module 300 is abnormal, the defective product is directly placed into the waste collection box 70, and a new solder sheet 400 is re-adsorbed or a new COS module 300 is picked up.

[0086] The clamping module 9 includes a transfer drive unit 91, a third support plate 92 driven by the transfer drive unit 91 to move left and right, a second motor 93 mounted on the third support plate 92, a fourth support plate 94 driven by the second motor 93 to move back and forth, a third cylinder 95 mounted on the fourth support plate 94, and a push rod 96 driven by the third cylinder 95 to move up and down. The push rod 96 extends horizontally and acts on the lifting rod 121. The push rod 96 acts on the bottom of the connecting part 1213 of the lifting rod 121, lifting the lifting rod 121 upward, thereby opening the clamping module 12. Since the two worktables 101 are arranged side by side, the transfer drive unit 91 drives the third support plate 92 to move left and right, covering the area of ​​the two clamping fixtures, so that several clamping modules 12 in the two clamping fixtures 1 can be opened. In other embodiments, if the multiple clamping fixtures are arranged in other ways, the driving method of the transfer drive 91 can be changed according to the arrangement of the clamping fixture 1, and no restrictions are imposed here.

[0087] When using the general-purpose COS assembly equipment 100 provided in this solution, the three-axis transfer module 6 drives the solder sheet adsorption and conveying mechanism 4 to move above the solder sheet feeding mechanism 2. The first cylinder 41 drives the first mounting plate 42 to descend, causing the adsorption rod 44 to adsorb a solder sheet 400. At the same time, the second CCD camera 83 takes a picture of the solder sheet 400 to check for defects. Then, the three-axis transfer module 6 moves the solder sheet COS clamping and conveying mechanism 5 to move above the COS feeding module 3. The second cylinder 51 drives the second mounting plate 52 to descend, and the electric cylinder 53 drives the gripper 54 to clamp a COS module 300. At the same time, the second CCD camera 83 takes a picture of the COS module 300 to check for defects. The three-axis transfer module 6 drives the solder sheet... The sheet adsorption and transport mechanism 4 and the COS clamping and transport mechanism 5 move above the first CCD camera 7. The first CCD camera 7 takes pictures of the clamped COS module 300 and the adsorbed solder sheet 400 to confirm whether there is a positional shift. If the angle of the solder sheet 400 shifts, the rotation drive 43 drives the adsorption rod 44 to rotate according to the picture results, and performs angle compensation on the position of the solder sheet 400 to correct the position of the solder sheet 400. If the position of the COS module 300 shifts, the second CCD camera 83 will take pictures of the COS in real time to confirm the position during the subsequent assembly of the COS module 300. The three-axis transfer module 6 adjusts the position of the COS module in real time to ensure the accuracy during COS assembly.After the positions of the solder sheet 400 and the COS module 300 are confirmed, the three-axis transfer module 6 drives the solder sheet adsorption and transport mechanism 4 and the COS clamping and transport mechanism 5 to move above the workbench 101 of the assembly station 10. At this time, the insulating base 200 has been positioned in the clamping fixture 1, and the clamping member 123 is pressed against the assembly slot of the COS module 300 to be installed on the insulating base 200. The clamping module 9 starts to work. The transfer drive 91 drives the third support plate 92 to move to the assembly slot to be assembled. The second motor 93 drives the fourth support plate 94 to move to the bottom of the connection part 1213 of the lifting rod 121. The third cylinder 95 drives the push rod 96 to move upward, so that the elastic member 124 is compressed, thereby making the clamping module 1 above the assembly slot to be assembled. 2. The assembly slot is opened to facilitate the placement of solder sheet 400 and COS module 300. The second CCD camera 83 first confirms the position of the assembly slot to be assembled. The first cylinder 41 of the solder sheet adsorption and transportation mechanism 4 drives the first mounting plate 42 to descend, so that the adsorption rod 44 places a solder sheet 400 onto the assembly slot. Then, the second cylinder 51 of the COS clamping and transportation mechanism 5 drives the second mounting plate 52 to descend, and the electric cylinder 53 drives the gripper 54 to place a COS module 300 onto the solder sheet 400. During the assembly of COS module 300, the second CCD camera 83 will take pictures of the COS in real time to confirm its position. The three-axis transfer module 6 adjusts the position of the COS module in real time to ensure the accuracy of COS assembly. After one COS module is assembled... After completion, the solder sheet adsorption and transportation mechanism 4 and the COS clamping and transportation mechanism 5 are used to transport new materials. The clamping module 9 reopens the next clamping module 12 and reassembles the next COS into the corresponding assembly slot. After the COS modules 300 are assembled in the front row of several assembly slots on the insulating base 200, the clamping fixture 1 is removed and rotated 180° to reassemble the COS modules 300 in the rear row of several assembly slots on the insulating base 200. After the COS modules 300 on the insulating base 200 are assembled, the clamping fixture 1 and the insulating base 200 are removed. At this time, the insulating base 200 is still positioned on the clamping fixture 1. Both the front and rear rows of the insulating base 200 have been assembled with COS modules 300, and each COS module is in good condition. Each COS module 300 is elastically clamped by the clamping module 12. Then, the clamping fixture 1 and the insulating base 200 are placed together in the welding setup (not shown in the figure) for welding. The melting of the solder sheet 400 fixes the COS module 300 onto the insulating base 200. During the transfer process, each COS module 300 is elastically clamped by the clamping module 12, therefore, the position of the COS module 300 will not shift. In the welding equipment, there is no need for manual fixing and clamping of each COS module 300 and the insulating base 200, saving tedious manual operations, improving the assembly and welding efficiency of the COS module 300, and enhancing the quality and precision of the assembly and welding, thus ensuring product quality.

[0088] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
