Description

Technical Field

[0001] The present invention relates to the technical field of optical module sealing glue, and in particular to a photoelectric coupling device, and in particular to a coupling method of an optical module sealing glue. Background Art

[0002] The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving. The function of the optical module is to convert electrical signals into optical signals at the transmitting end. After being transmitted through optical fibers, the receiving end converts the optical signals into electrical signals.

[0003] Chinese patent CN219591349U discloses an integrated optical module packaging device, including a base; a rotating plate is rotatably connected to the middle part of the base; a connecting plate is fixedly connected to the side of the rotating plate away from the base; a load-bearing plate is fixedly connected to the side of the connecting plate away from the rotating plate; brackets are fixedly connected to both ends of the top of the base; a clamp is slidably connected between two groups of the brackets; one group of the two groups of the brackets is movably connected to a telescopic rod on the side close to the rotating plate; the operator starts the motor so that the motor drives the rotating plate on the rotating column to rotate, and because the teeth on the rotating plate are engaged with the grooves on the rotating plate, when the motor drives the rotating plate to rotate one circle, the teeth push the rotating plate to rotate one circle due to inertia, so that a certain amount of glue in the pipeline is evenly applied to the edge of the load-bearing plate, so that the glue between the lens and the circuit board is evenly applied, so that the two are firmly bonded.

[0004] Although the above device can effectively ensure the uniformity of glue dispensing on the circuit board and then bond the lens to the circuit board, the process of bonding the lens to the circuit board is divided into two steps, which not only limits the ability to quickly combine the glued circuit board and the lens, but also directly reduces work efficiency and prolongs the overall operation time. Summary of the invention

[0012] Preferably, a connecting plate is provided between the two gear rings, symmetrical spring telescopic rods are provided at the bottom of the connecting plate, and pressure plates are provided at the telescopic ends of the two spring telescopic rods.

[0014] Preferably, a plurality of leakage holes for dropping glue are opened inside the scraper block, a frame is arranged outside the support column, and a collecting drawer for collecting glue is slidably arranged inside the frame.

[0015] A coupling method for an optical module sealing adhesive comprises the following steps:

[0016] S1: First, place the circuit board that needs to be sealed on the top of the conveyor belt, then start the pump body and the drive motor. When the drive motor is working, it will drive the driving wheel to rotate, and then the driving wheel cooperates with the driven wheel to drive the driving rod and the second synchronous wheel to rotate. The second synchronous wheel cooperates with the second synchronous belt to drive the stirring rod to rotate. The stirring rod can continuously stir the glue inside the glue bucket, so that the glue is always in a flowing state to prevent the glue from solidifying. While stirring, the stirring rod will also drive the first synchronous wheel to rotate. The first synchronous wheel cooperates with the first synchronous belt to drive the second rotating rod to rotate. At the same time, the turntable on the top of the second rotating rod will also rotate, thereby driving the chuck and the resistance rod on the top of the turntable to rotate. The chuck and the resistance rod cooperate with the special-shaped block to make The first rotating rod and the second bevel gear will stop for a period of time every time they rotate ninety degrees, and the first bevel gear, the connecting rod and the transmission roller will also stop for a period of time every time they rotate ninety degrees. The intermittent operation of the transmission roller will drive the conveyor belt to stop moving after moving a certain distance. When the circuit board moves to the bottom of the brush, the pump body has transported the glue inside the glue bucket to the bristles of the brush. Therefore, when the circuit board collides with the bristles of the brush, the top of the circuit board will be evenly coated with glue. When the top of the circuit board is coated with glue and moves a certain distance, it will stop moving under the operation of the transmission roller and the conveyor belt. At this time, the rotating frame cooperates with the electric push rod and the mechanical claw to place the lens inside the lens placement frame on top of the circuit board so that it can be bonded to the lens.

[0017] S2: After the circuit board and the lens are bonded, they will move a certain distance and then stop moving. At this time, since the driving rod drives the fourth bevel gear to rotate, the rotating fourth bevel gear can drive the third bevel gear and the third rotating rod to rotate. While the third rotating rod is rotating, it will also drive the two half gears to rotate. The two half gears are respectively installed inside the two gear rings. Therefore, the two half gears drive the two gear rings to reciprocate up and down while rotating. A limit block is set on the side wall of the gear ring to prevent the gear ring from positionally shifting while moving. When the gear ring moves downward, it will also drive the connecting plate, the spring telescopic rod and the pressure plate to move downward. That is, when the circuit board moves a certain distance and stops moving, the mechanical claw places the lens above the circuit board to complete the bonding with the circuit board. When the bonded circuit board and lens move a certain distance and stop moving, the pressure plate moves downward to compact the bonded circuit board and lens to make the connection more firmly.

[0018] S3: When the circuit board and the lens are firmly bonded, they will move with the conveyor belt and finally flow into the collection frame along the scraper block, which is convenient for the next step. A rubber pad is arranged inside the collection frame to prevent the circuit board and the lens from colliding with the inner wall of the collection frame. At the same time, the scraper block can be used to scrape out the glue remaining on the surface of the conveyor belt to prevent the glue from solidifying on the surface of the conveyor belt. The scraped glue will fall into the inside of the collection drawer through the leakage hole inside the scraper block.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The intermittent operation of the transmission roller will drive the conveyor belt to stop moving after moving a certain distance. When the circuit board moves to the bottom of the brush, the pump body has transported the glue inside the glue bucket to the bristles of the brush. Therefore, when the circuit board collides with the bristles of the brush, the top of the circuit board will be evenly coated with glue. When the top of the circuit board is coated with glue and moves a certain distance, it will stop moving under the operation of the transmission roller and the conveyor belt. At this time, the rotating frame cooperates with the electric push rod and the mechanical claw to place the lens inside the lens placement frame on top of the circuit board so that it can be bonded to the lens.

[0021] The third rotating rod will also drive the two half gears to rotate when rotating, and the two half gears are respectively installed inside the two gear rings. Therefore, the two half gears drive the two gear rings to reciprocate up and down when rotating. Limiting blocks are set on the side walls of the gear rings to prevent the gear rings from positional deviation when moving. When the gear rings move downward, they will also drive the connecting plate, the spring telescopic rod and the pressure plate to move downward to compact the bonded circuit board and lens.

One end of the glue inlet pipe 26 extends to the inside of the glue bucket 7. The output end of the pump body 3 is connected to a glue outlet pipe 27.

The outer side wall of the baffle 2 is provided with a lens placement frame 5 and an electric rotating block 30. The top of the electric rotating block 30 is provided with a rotating frame 4. The inside of the rotating frame 4 is provided with an electric push rod 31. The telescopic end of the electric push rod 31 is provided with a mechanical claw 32.

[0036] The intermittent operation of the transmission roller 13 will drive the conveyor belt 11 to stop moving after moving a certain distance. When the circuit board moves to the bottom of the brush 28, the pump body 3 has transported the glue inside the glue bucket 7 to the bristles of the brush 28. Therefore, when the circuit board collides with the bristles of the brush 28, the top of the circuit board will be evenly coated with glue. When the top of the circuit board is coated with glue and moves a certain distance, it will stop moving under the operation of the transmission roller 13 and the conveyor belt 11. At this time, the rotating frame 4 cooperates with the electric push rod 31 and the mechanical claw 32 to place the lens inside the lens placement frame 5 above the circuit board so that it is bonded to the lens.

[0037] Figure 4 As shown, the top of the base 1 is rotatably provided with a first rotating rod 15 and a second rotating rod 16, the outside of the second rotating rod 16 is provided with a rotating disk 22, the top of the rotating disk 22 is provided with a chuck 21 and a resistance rod 20, the outside of the first rotating rod 15 is provided with a special-shaped block 19 that cooperates with the resistance rod 20, and the top of the first rotating rod 15 is provided with a second bevel gear 18 that meshes with the first bevel gear 17.

[0039] like Figure 4 and Figure 5 As shown, first synchronous wheels 23 are disposed outside the second rotating rod 16 and the stirring rod 25 , and the two first synchronous wheels 23 are connected by a first synchronous belt 24 .

[0040] The cooperation between the first synchronous wheels 23 and the second synchronous wheels 23 can make the second rotating rod 16 and the stirring rod 25 rotate synchronously.

[0043] like Figure 5 and Figure 8 As shown, the outsides of the driving rod 36 and the stirring rod 25 are both provided with second synchronous wheels 37 , and the two second synchronous wheels 37 are connected by a second synchronous belt 38 .

[0044] The cooperation between the second synchronous wheel 37 and the second synchronous belt 38 can make the driving rod 36 and the stirring rod 25 rotate synchronously.

[0045] like Fig. 9 As shown, a mounting plate 6 is provided on the top of the two baffles 2, and a gear ring 42 is slidably provided on the opposite side of the two mounting plates 6. A limit block 44 is provided on the side of the gear ring 42 close to the mounting plate 6, and a limit groove for the limit block 44 to move is provided on the side wall of the mounting plate 6. The interior of the two gear rings 42 is meshed with a half gear 43, and the two half gears 43 are arranged on the outside of the third rotating rod 33. One end of the third rotating rod 33 is provided with a third bevel gear 34 meshed with the fourth bevel gear 35.

[0046] The rotation of the half gear 43 can cause the gear ring 42 to reciprocate up and down.

[0047] like Fig. 9 As shown, a connecting plate 45 is provided between the two gear rings 42 , a symmetrical spring telescopic rod 46 is provided at the bottom of the connecting plate 45 , and a pressing plate 47 is provided at the telescopic ends of the two spring telescopic rods 46 .

[0048] The pressing plate 47 is moved downward to compact the bonded circuit board and lens, making the connection more secure.

[0049] like Fig.10 As shown, a support column 8 is arranged on the top of the base 1, a collecting frame 9 is arranged on the top of the support column 8, a rubber pad 50 is arranged inside the collecting frame 9, a scraper block 10 is arranged on the side wall of the collecting frame 9, and one end of the scraper block 10 is in contact with the conveyor belt 11.

[0050] The scraper block 10 can be used to scrape off the glue remaining on the surface of the conveyor belt 11 to prevent the glue from solidifying on the surface of the conveyor belt 11 .

[0051] like Fig.10 As shown, a plurality of leak holes for dropping glue are provided inside the scraper block 10, a frame 48 is provided outside the support column 8, and a collecting drawer 49 for collecting glue is slidably provided inside the frame 48.

[0052] The glue scraped out through the leakage hole will fall into the inside of the collecting bin 49 through the leakage hole inside the scraper block 10.

[0053] A coupling method for an optical module sealing adhesive comprises the following steps:

[0054] S1: First, place the circuit board to be sealed on the top of the conveyor belt 11, then start the pump body 3 and the drive motor 41. When the drive motor 41 is working, it will drive the driving wheel 39 to rotate, and then the driving wheel 39 cooperates with the driven wheel 40 to drive the driving rod 36 and the second synchronous wheel 37 to rotate. The second synchronous wheel 37 cooperates with the second synchronous belt 38 to drive the stirring rod 25 to rotate. The stirring rod 25 can continuously stir the glue inside the glue bucket 7, so that the glue is always in a flowing state to prevent the glue from solidifying. While stirring, the stirring rod 25 will also drive the first synchronous wheel 23 to rotate. The first synchronous wheel 23 cooperates with the first synchronous belt 24 to drive the second rotating rod 16 to rotate. At the same time, the turntable 22 on the top of the second rotating rod 16 will also rotate, thereby driving the chuck 21 and the resistance rod 20 on the top of the turntable 22 to rotate. The operation of the special-shaped block 19 can make the first rotating rod 15 and the second bevel gear 18 stop for a period of time every time they rotate ninety degrees, and at the same time, it will also drive the first bevel gear 17, the connecting rod 14 and the transmission roller 13 to stop for a period of time every time they rotate ninety degrees. The intermittent operation of the transmission roller 13 will drive the conveyor belt 11 to stop moving after moving a certain distance. When the circuit board moves to the bottom of the brush 28, the pump body 3 has transported the glue inside the glue bucket 7 to the bristles of the brush 28. Therefore, when the circuit board collides with the bristles of the brush 28, the top of the circuit board will be evenly coated with glue. When the top of the circuit board is coated with glue and moves a certain distance, it will stop moving under the operation of the transmission roller 13 and the conveyor belt 11. At this time, the rotating frame 4 cooperates with the electric push rod 31 and the mechanical claw 32 to place the lens inside the lens placement frame 5 above the circuit board so that it is bonded to the lens.

[0055] S2: After the circuit board and the lens are bonded, they move a certain distance and then stop moving. At this time, the driving rod 36 drives the fourth bevel gear 35 to rotate. The rotating fourth bevel gear 35 can drive the third bevel gear 34 and the third rotating rod 33 to rotate. The third rotating rod 33 also drives the two half gears 43 to rotate while rotating. The two half gears 43 are respectively installed in the two gear rings 42. Therefore, the two half gears 43 drive the two gear rings 42 to reciprocate up and down while rotating. A limit block 44 is provided on the side wall of the gear ring 42 to prevent the gear ring 42 from shifting in position while moving. When the gear ring 42 moves downward, it also drives the connecting plate 45, the spring telescopic rod 46 and the pressing plate 47 to move downward. That is, when the circuit board moves a certain distance and stops moving, the mechanical claw 32 places the lens above the circuit board to complete the bonding with the circuit board. When the bonded circuit board and lens move a certain distance and stop moving, the pressing plate 47 moves downward to compact the bonded circuit board and lens to make the connection more firmly.

[0056] S3: When the circuit board and the lens are firmly bonded, they will move along the conveyor belt 11 and finally flow into the collection frame 9 along the scraper block 10, which is convenient for the next step of work. A rubber pad 50 is arranged inside the collection frame 9 to prevent the circuit board and the lens from colliding with the inner wall of the collection frame 9. At the same time, the scraper block 10 can be used to scrape off the glue remaining on the surface of the conveyor belt 11 to prevent the glue from solidifying on the surface of the conveyor belt 11. The scraped glue will fall into the collection drawer 49 through the leakage hole inside the scraper block 10.

[0057] The above embodiments only express a photoelectric coupling device and a coupling method or several implementation methods for optical module sealing of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.

When the driving motor (41) is working, it drives the driving wheel (39) to rotate, and then the driving wheel (39) cooperates with the driven wheel (40) to drive the driving rod (36) and the second synchronous wheel (37) to rotate. The second synchronous wheel (37) cooperates with the second synchronous belt (38) to drive the stirring rod (25) to rotate, and the stirring rod (25) can be used to stir the glue bucket (7). The glue at the top of the rotating rod (22) is continuously stirred to keep the glue in a flowing state, thereby preventing the glue from solidifying. The stirring rod (25) also drives the first synchronous wheel (23) to rotate while stirring. The first synchronous wheel (23) cooperates with the first synchronous belt (24) to drive the second rotating rod (16) to rotate. At the same time, the rotating disk (22) at the top of the rotating disk (22) is also rotated, thereby driving the chuck (21) and the abutment rod (20) at the top of the rotating disk (22) to rotate. The rod (20) cooperates with the special-shaped block (19) to make the first rotating rod (15) and the second bevel gear (18) stop for a period of time every time they rotate 90 degrees, and at the same time, the first bevel gear (17), the connecting rod (14) and the transmission roller (13) stop for a period of time every time they rotate 90 degrees. The intermittent operation of the transmission roller (13) causes the conveyor belt (11) to stop moving after moving a certain distance. When the circuit board moves to the bottom of the brush (28), the pump body (3) has already filled the rubber The glue inside the bucket (7) is transported to the bristles of the brush (28), so when the circuit board and the bristles of the brush (28) collide, the top of the circuit board will be evenly coated with glue. After the top of the circuit board coated with glue moves a certain distance, it stops moving under the operation of the transmission roller (13) and the conveyor belt (11). At this time, the rotating frame (4) cooperates with the electric push rod (31) and the mechanical claw (32) to place the lens inside the lens placement frame (5) above the circuit board, so that the lens and the circuit board are bonded. S2: After the circuit board and the lens are bonded, they move for a certain distance and then stop moving. At this time, the driving rod (36) drives the fourth bevel gear (35) to rotate. The rotating fourth bevel gear (35) can drive the third bevel gear (34) and the third rotating rod (33) to rotate. The third rotating rod (33) also drives the two half gears (43) to rotate while rotating. The two half gears (43) are respectively installed inside the two gear rings (42). Therefore, the two half gears (43) drive the two gear rings (42) to reciprocate up and down while rotating. A limit block (44) is provided on the side wall to prevent the gear ring (42) from being offset in position while moving. When the gear ring (42) moves downward, it also drives the connecting plate (45), the spring telescopic rod (46) and the pressing plate (47) to move downward. That is, when the circuit board moves a certain distance and stops moving, the mechanical claw (32) places the lens on the top of the circuit board so that the lens and the circuit board are bonded. When the bonded circuit board and lens move a certain distance and stop moving, the pressing plate (47) moves downward to compact the bonded circuit board and lens so that the connection is more secure. S3: When the circuit board and the lens are firmly bonded, they will move along the conveyor belt (11) and finally flow into the collection frame (9) along the scraper block (10), facilitating the next step. A rubber pad (50) is provided inside the collection frame (9) to prevent the circuit board and the lens from colliding with the inner wall of the collection frame (9). At the same time, the scraper block (10) can be used to scrape off the glue remaining on the surface of the conveyor belt (11) to prevent the glue from solidifying on the surface of the conveyor belt (11). The scraped glue will fall into the inside of the collection drawer (49) through the leakage hole inside the scraper block (10).
