Description

[0002] In automotive headlights, the high and low beams are gradually developing towards an extremely narrow shape. Such an extremely narrow low-beam module plays an important role in the overall lamp space and cost, and is a common and urgently developing direction in actual design and manufacturing work.

[0003] Currently, the processing and production of the extremely narrow low-beam module realizes the low-beam function of the automotive headlight through the reflector bowl and the inner lens. Among them, the inner lens and the PCBA component are fixed in a sandwich clamping manner through the reflector bowl and the module bracket. Most of the overall processing procedures are manually assembled by workers. For example, when manufacturing the PCBA component, it is usually necessary for workers to apply thermal conductive glue on the PCBA board and then rivet it on the radiator, and then rivet 3 light-shielding sheets on the radiator in sequence to form the PCBA component. Corresponding riveting posts are set on the radiator. It is necessary to align the riveting holes on the PCBA board and the light-shielding sheets with the riveting posts for sequential assembly and then perform riveting. However, the manual operation speed is slow, the fatigue intensity of the workers is high, the efficiency is reduced, and the riveting of the PCBA board and the light-shielding sheet is carried out in two times, greatly reducing the processing speed.

[0054] See also Figure 1-12 The present invention provides a technical solution: an automatic riveting device for a light-emitting module with a narrow light-emitting surface and a processing method thereof, comprising a loading component 1, a moving component 2, a PCBA assembly component 3, an adsorption component 4, a blanking component 5 and a riveting component 6; wherein,

[0055] The moving component 2 is used to carry the radiator body 701 to move;

[0056] The moving component 2 passes through the lower side of the PCBA assembly component 3, the adsorption component 4 and the riveting component 6 in the order of the process;

[0057] The loading assembly 1 includes a discharge barrel 101 and a pushing mechanism. Several PCBA boards 7 are stacked in the discharge barrel 101. The pushing mechanism is used to push a single PCBA board 7 from the discharge barrel 101 into the PCBA assembly assembly 3.

[0058] The PCBA assembly component 3 is used to push the received PCBA board 7 onto the radiator body 701 located on the moving component 2;

[0059] The blanking component 5 includes a blanking cylinder 501 and a moving clamping plate 502. A number of light shielding sheet bodies 702 are stacked in the blanking cylinder 501. The moving clamping plate 502 is used to separately separate a single light shielding sheet body 702 from the blanking cylinder 501 and move it to the adsorption component 4;

[0060] The adsorption component 4 is used to adsorb the light shielding sheet body 702 and push it onto the radiator body 701 with the PCBA board 7 already assembled;

[0061] The riveting component 6 is used to rivet the radiator body 701 with the PCBA board 7 and the light shielding sheet body 702 already assembled to form a PCBA component.

[0062] Specifically, the staff first place the radiator body 701 coated with thermal conductive adhesive on the moving component 2. The moving component 2 carries the radiator body 701 to move, and successively passes through the PCBA assembly component 3, the adsorption component 4, and the riveting component 6, realizing the assembly of the PCBA board 7, the assembly of the light shielding sheet body 702 on the radiator body 701 in sequence, and finally performing unified riveting to form a PCBA component, greatly improving the riveting speed and greatly reducing the labor fatigue intensity, realizing the integrated automated processing and production of the PCBA component. Among them, there are also a feeding component 1 and a blanking component 5 to automatically feed the PCBA assembly component 3 and the adsorption component 4. Among them, there are a number of PCBA boards 7 stacked in advance in the feeding cylinder 101. Through the pushing mechanism, a single PCBA board 7 is pushed out from it and enters the PCBA assembly component 3. Then the PCBA assembly component 3 pushes the PCBA board 7 onto the radiator body 701 on the moving component 2 to complete the assembly of the PCBA board 7. Then the moving component 2 drives the radiator body 701 to continue moving to the lower side of the adsorption component 4. Similarly, a number of light shielding sheet bodies 702 are stacked in the blanking cylinder 501 in advance. The moving clamping plate 502 separates a single light shielding sheet body 702 from it, and then brings it to the adsorption component 4. The adsorption component 4 adsorbs the light shielding sheet body 702 and brings it onto the radiator body 701 with the PCBA board 7 already assembled to complete the assembly of the light shielding sheet body 702. Finally, the moving component 2 brings it into the riveting component 6 to perform unified riveting on the PCBA board 7 and the light shielding sheet body 702, with high riveting efficiency, thus completing the automated production of the PCBA component.

[0063] The PCBA assembly component 3 includes an upper cover plate 301. A limiting frame 302 is fixedly connected to the lower end of the upper cover plate 301. The inner wall of the limiting frame 302 is in clearance fit with the PCBA board 7. A feeding port 303 is formed in one side of the limiting frame 302. The feeding port 303 is used to receive the PCBA board 7 pushed in by the feeding component 1. Two limiting plates 305 are slidably fitted to the lower sides of both ends of the limiting frame 302. The two limiting plates 305 are oppositely arranged at both ends of the limiting frame 302. The length of the limiting plate 305 extends to the inner side of the limiting frame 302. The limiting plate 305 is used to block the PCBA board 7 in the limiting frame 302 from falling. A triangular wedge 306 is fixedly connected to the lower end of the limiting plate 305. The inclined surfaces of the triangular wedges 306 are oppositely arranged. A baffle 304 is fixedly connected to one end of the limiting plate 305 located outside the limiting frame 302. Guide rods 307 are arranged at both ends of the baffle 304. One end of the guide rod 307 is fixedly connected to the limiting frame 302. The guide rod 307 penetrates through the baffle 304 and is slidably fitted with it. A stopper is fixedly connected to the outer end of the guide rod 307. A first spring is arranged outside the guide rod 307. Both ends of the first spring are respectively connected to the stopper and the baffle 304;

[0064] The moving component 2 includes a positioning frame 201. The positioning frame 201 is used to limit the position of the PCBA board 7 when the moving component 2 moves. The positioning frame 201 is oppositely arranged to the limiting frame 302. The inclined surfaces of the triangular wedges 306 are oppositely arranged to the positions at both ends of the positioning frame 201. A plurality of groups of guide rods 308 are arranged at the lower end of the limiting frame 302. A plurality of groups of riveting posts are arranged at the upper end of the radiator body 701. Corresponding riveting holes are formed in the PCBA board 7.

[0065] Specifically, the feeding component 1 first pushes a single PCBA board 7 into the limiting frame 302 from the feeding port 303. The limiting frame 302 positions the PCBA board 7 and guides its downward movement, causing the PCBA board 7 to fall to the lowermost end of the limiting frame 302. Then, the limiting plate 305 supports the PCBA board 7 to prevent it from falling further. When the moving component 2 moves the radiator body 701 to the lower part of the PCBA assembly component 3, at this time, the triangular wedge 306 corresponds to the positioning frame 201. The upper cover 301, the limiting frame 302, and the limiting plate 305 are controlled by a driving mechanism such as a cylinder assembly to drive the PCBA board 7 downward. The inclined surface of the triangular wedge 306 contacts the upper end surface of the positioning frame 201, causing the triangular wedge 306 to move outward along the inclined surface and drive the limiting plate 305 and the baffle 304 to move together. The baffle 304 moves along the guide rod 307 for guiding, causing the limiting plate 305 to gradually release the supporting state of the PCBA board 7 until the upper end surface of the positioning frame 201 contacts the limiting plate 305. At this time, the PCBA board 7 completely loses support and falls under the action of its own gravity onto the radiator body 701 within the positioning frame 201. By arranging a number of guide rods 308 on the lower end surface of the limiting frame 302, the guide rods 308 extend into the positioning frame 201 and contact the radiator body 701, further guiding the PCBA board 7 when it falls onto the radiator body 701, so that its riveting holes can be aligned with the riveting posts for assembly, with good assembly accuracy. After the assembly is completed, the PCBA assembly component 3 is reset. At this time, the triangular wedge 306 separates from the positioning frame 201. Under the action of the first spring, the limiting plate 305 returns to its original position, facilitating the next assembly. The automatic assembly of the PCBA board 7 is realized, and only a single cylinder assembly is used for driving to complete the assembly, which is simple and convenient and reduces the processing cost.

[0066] A cylinder part is arranged on the upper side of the upper cover 301. A piston rod 309 is arranged on the lower side of the cylinder part. The piston rod 309 penetrates through the upper cover 301 and is in sliding fit with it. The lower end of the piston rod 309 is fixedly connected to a disc 310. A number of first telescopic rods 311 are arranged on the upper side of the disc 310. The upper ends of the first telescopic rods 311 are connected to the upper cover 301. A second spring is arranged on the outer side of the first telescopic rods 311. The two ends of the second spring are respectively connected to the upper cover 301 and the disc 310.

[0067] Specifically, when assembling the PCBA board 7, the cylinder part is activated to drive the piston rod 309 to extend. The piston rod 309 descends to push the disc 310, and drives the upper cover plate 301 to descend through the first telescopic rod 311 and the second spring. When the PCBA board 7 loses the support of the limiting plate 305 and falls downward only by its own gravity, there may be a situation where the PCBA board 7 is not fully stuck on the radiator body 701. At this time, the driving piston rod 309 can continue to descend, and the piston rod 309 thus pushes the disc 310 to continue descending. At this time, the limiting frame 302 contacts the positioning frame 201, making the upper cover plate 301 unable to move further, so that the first telescopic rod 311 and the second spring are stretched until the disc 310 contacts the PCBA board 7 and presses it completely onto the radiator body 701 to complete the assembly. The assembly effect is good. The functions of driving the PCBA board 7 to descend and pressing the PCBA board 7 can be realized by a single cylinder part, with strong practicability and cost savings for additional driving parts.

[0068] A top plate 8 is arranged on the upper side of the feeding cylinder 101. The feeding cylinder 101 penetrates through the top plate 8 and is fixedly connected thereto. A plurality of groups of transmission rollers 102 are rotatably connected to the lower end of the feeding cylinder 101. An outlet is arranged on the lower side of one end of the feeding cylinder 101 close to the feeding port 303. The distance between the top end of the outlet and the top end of the transmission rollers 102 is equal to the thickness of a single PCBA board 7. The outlet is arranged opposite to the feeding port 303. The pushing mechanism is arranged on the opposite side of the outlet on the feeding cylinder 101. The pushing mechanism includes two pushing plates 103. The pushing plates 103 penetrate through the feeding cylinder 101 and are slidably matched therewith. The thickness of the pushing plates 103 is equal to the thickness of the PCBA board 7. The outer end of the pushing plate 103 is fixedly connected with a pushing board 104. A threaded rod 105 is arranged in the middle of the pushing board 104. The threaded rod 105 penetrates through the pushing board 104 and is threadedly connected thereto. One end of the threaded rod 105 is provided with a motor part 106, and the motor part 106 is connected to the feeding cylinder 101.

[0069] Specifically, the staff can stack a number of PCBA boards 7 in the feeding cylinder 101 in advance. The lowermost PCBA board 7 falls on a plurality of transmission rollers 102. Since the distance between the top end of the outlet and the top end of the transmission rollers 102 is equal to the thickness of a single PCBA board 7 (as Figure 7 shown), and the thickness of the pushing plate 103 is equal to the thickness of the PCBA board 7 (as Figure 8As shown, when the pusher plate 103 pushes the lowermost PCBA board 7, the PCBA board 7 rolls along the transmission roller 102, thereby reducing the friction of the lower side of the PCBA board 7 during movement, passing through the discharge port and entering the feed port 303 of the limit frame 302, and finally entering the limit frame 302 for assembly. The several PCBA boards 7 on the upper side will be blocked by the material feeding cylinder 101 and remain in the material feeding cylinder 101. When the pusher plate 103 returns to its original position, the upper PCBA board 7 will fall onto the transmission roller 102 to prepare for the next pushing operation. Among them, by starting the motor component 106 to drive the threaded rod 105 to rotate, the threaded rod 105 is threadedly connected to the push plate 104, and the two pusher plates 103 penetrate the material feeding cylinder 101, so that the push plate 104 pushes the two pusher plates 103 to move, realizing the pushing operation, thus realizing the automatic feeding while separating the PCBA boards 7 individually, without manual feeding, and having high working efficiency.

[0070] On the upper side of the end of the pusher plate 103 away from the push plate 104, a slope block 107 is fixedly connected. The slope surface of the slope block 107 corresponds to the PCBA board 7. At the upper end of the pusher plate 103, a double straight rod 108 is fixedly connected. The height of the double straight rod 108 is equal to the height of the slope block 107. Several rolling rods 109 are rotatably connected to the middle side of the double straight rod 108.

[0071] Specifically, the upper end of the pusher plate 103 is provided with a slope block 107, a double straight rod 108, and rolling rods 109, so that when the pusher plate 103 pushes the PCBA board 7 for feeding, the upper PCBA board 7 will be lifted along the slope block 107 and come into contact with several rolling rods 109, thereby reducing the friction between the upper PCBA board 7 and the PCBA board 7 being pushed. The upper PCBA board 7 continuously moves on the rolling rods 109 and the rolling rods 109 roll accordingly, thereby reducing the friction between the two and ensuring the surface quality of the PCBA board 7.

[0072] At the lower end of the positioning frame 201, a moving frame 202 is fixedly connected. The radiator body 701 is placed in the moving frame 202. Wheel grooves are opened at the lower ends of both sides of the moving frame 202. At the lower ends of the four corners of the top plate 8, support columns are fixedly connected. At the lower side of the support columns, a pair of raceways 801 are fixedly connected. Several groups of rolling wheels 802 are rotatably connected to the upper side of the raceways 801. The rolling wheels 802 are in contact with the wheel grooves, and the rolling wheels 802 are driven to rotate by a motor assembly.

[0073] Specifically, by driving the rolling wheels 802 through the motor assembly, the rolling wheels 802 drive the moving frame 202 to drive the positioning frame 201 and the radiator body 701 to move along the raceways 801. Among them, the wheel grooves are in contact with the rolling wheels 802 for movement guidance.

[0074] There are several feeding cylinders 501. The feeding cylinders 501 penetrate through the top plate 8 and are fixedly connected thereto. A fixing rod 503 is fixedly connected to the end of the feeding cylinder 501 away from the adsorption assembly 4. A stop block is fixedly connected to the other end of the fixing rod 503. A sliding plate 504 is arranged on the fixing rod 503. The fixing rod 503 penetrates through the sliding plate 504 and is in sliding fit therewith. A third spring is arranged on the outer side of the fixing rod 503. The two ends of the third spring are respectively connected to the stop block and the sliding plate 504. A lower cover plate 505 is fixedly connected to the lower end of the sliding plate 504. The upper surface of the lower cover plate 505 is in contact with the light shielding plate body 702 and at the same time in contact with the lower end surface of the feeding cylinder 501.

[0075] Specifically, the staff stacks a number of light shielding plate bodies 702 in several feeding cylinders 501 in advance. A lower cover plate 505 is arranged at the lower end of the feeding cylinder 501 to support it and prevent it from falling further. One end of the lower cover plate 505 is fixed with a sliding plate 504. The sliding plate 504 slides along the fixing rod 503, and a third spring is arranged to hold the sliding plate 504. Then, continuous feeding is carried out by moving the clamping plate 502.

[0076] The two sides of the moving clamping plate 502 are in sliding fit with the slide rails 507. Connecting rods 508 are fixedly connected to the four corners of the slide rails 507. The upper ends of the connecting rods 508 are fixedly connected to the top plate 8. The moving clamping plate 502 is driven to move by a cylinder assembly. A number of material clamping seats 506 are fixedly connected to the upper side of the moving clamping plate 502. The positions of the material clamping seats 506 correspond to the positions of the feeding cylinders 501. A material clamping groove is opened on the upper side of the material clamping seat 506. The height of the material clamping groove is equal to the thickness of the light shielding plate body 702. The lower end surface of the feeding cylinder 501 and the upper end surface of the material clamping seat 506 are on the same horizontal line.

[0077] Specifically, the moving clamping plate 502 is driven by a cylinder assembly to move along the slide rails 507. When the moving clamping plate 502 drives a number of material clamping seats 506 to move towards the feeding cylinder 501, since the lower end surface of the feeding cylinder 501 and the upper end surface of the material clamping seat 506 are on the same horizontal line, therefore, the material clamping seat 506 will push the lower cover plate 505 away from the lower end of the feeding cylinder 501, causing the upper light shielding plate body 702 to fall into the material clamping groove opened in the material clamping seat 506 under the action of its own gravity. Since the height of the material clamping groove is equal to the thickness of the light shielding plate body 702, the single light shielding plate body 702 at the lowermost end of the feeding cylinder 501 just fits into the material clamping groove. Then the moving clamping plate 502 resets, thereby taking away the light shielding plate body 702, while the upper several light shielding plate bodies 702 are blocked by the feeding cylinder 501 and cannot move along. At this time, the lower cover plate 505 moves back to the lower side of the feeding cylinder 501 under the reset action of the third spring, and supports the upper several light shielding plate bodies 702 again, thus completing the automatic separation and feeding of the light shielding plate body 702.

[0078] The adsorption assembly 4 includes a number of groups of hollow suction heads 401. The positions of the hollow suction heads 401 are set corresponding to the positions of the blanking seats 506. A hollow tube 402 is provided at the upper end of the hollow suction head 401. A lifting plate 403 is provided at the upper end of the hollow tube 402. An air pump 404 is fixedly connected to the upper end of the lifting plate 403. The air pump 404 is connected to the hollow tube 402 through a hose. Telescopic members are provided on the upper sides of the four corners of the lifting plate 403. The telescopic members are connected to the top plate 8. The lifting plate 403 is driven to move by a cylinder assembly.

[0079] Specifically, the light-shielding sheet body 702 located in the blanking groove is then brought to the lower end of the hollow suction head 401 by the moving clamping plate 502. The hollow suction head 401 is driven by the lifting plate 403 to descend. Through the air pump 404 and the hollow tube 402, the light-shielding sheet body 702 is adsorbed. Then the lifting plate 403 ascends, taking the light-shielding sheet body 702 out of the blanking seat 506. Subsequently, the moving clamping plate 502 continues to move towards the blanking cylinder 501. At this time, the moving assembly 2 drives the radiator body 701 equipped with the PCBA board 7 to move to the lower side of a number of hollow suction heads 401. At this time, the lifting plate 403 continues to drive the hollow suction head 401 to descend, placing the light-shielding sheet body 702 on the upper side of the radiator body 701 to complete the assembly, realizing the automatic assembly of the light-shielding sheet body 702.

[0080] The riveting assembly 6 includes a number of groups of riveting heads 601. The positions of the number of groups of riveting heads 601 correspond to the positions of the riveting posts. A lifting mechanism is provided at the upper end of the riveting head 601. The lifting mechanism drives the riveting head 601 to perform riveting through a cylinder member.

[0081] Specifically, when the PCBA board 7 and the light-shielding sheet body 702 are both assembled, the moving assembly 2 at this time moves to the lower side of a number of riveting heads 601. The lifting mechanism drives the riveting head 601 to descend, simultaneously riveting the PCBA board 7 and the light-shielding sheet body 702 to form a PCBA assembly, eliminating the need for separate secondary riveting and improving the riveting efficiency.

[0082] The processing of the light-emitting module includes the following steps:

[0083] The heat-conducting glue preparation step S1: Apply heat-conducting glue to the surface of the radiator body 701 that makes up the PCBA assembly and place it in the moving assembly 2 to move to the next step;

[0084] The PCBA board assembly step S2: Use the PCBA assembly component 3 to place the PCBA board 7 on the radiator body 701 with the riveting holes and riveting posts corresponding to each other, and then move to the next step;

[0085] Light shielding sheet assembling step S3: Use the adsorption component 4 to place the light shielding sheet body 702 on the radiator body 701 with the riveting holes and riveting posts corresponding to each other, and then move to the next step;

[0086] Riveting step S4: Rivet the assembled PCBA board 7, light shielding sheet body 702 and radiator body 701 together to form a PCBA component;

[0087] Assembly step S5: Assemble the PCBA component on the reflector bowl, then assemble the module lens, and finally cover the module bracket and tighten 4 fastening screws to form a sub-assembly of the module component.
