Description

Technical Field

[0001] This invention belongs to the field of automotive lighting component assembly technology, specifically relating to an online hot riveting equipment and method for automotive lighting components. Background Technology

[0002] Currently, hot riveting of automotive lighting components is mainly done offline using single-machine equipment. The existing technical solution involves manually placing the automotive lighting components on a fixture, pressing the start button, and then the upper mold's hot riveting assembly is driven down by a vertical cylinder to perform the riveting. After riveting, air is blown to cool the riveting points, and after completion, the vertical cylinder drives the upper mold back to its original position.

[0003] The original hot riveting solution required manual handling of parts, which significantly impacted the cycle time, especially when multiple products needed to be hot riveted. Some equipment might use a chain to transport the products, but when the hot riveting assembly of the upper mold is driven down by a vertical cylinder to perform riveting, the product needs to be pressed tightly. This can easily damage the tooling or chain located below the product. Furthermore, conventional single-machine equipment cannot perform secondary positioning. When the chain transports the product to the bottom of the hot riveting assembly of the upper mold, the positioning accuracy cannot be guaranteed, thus making it impossible to ensure the consistency of product riveting. Summary of the Invention

[0004] In view of this, in order to solve the problems existing in the prior art, the purpose of this invention is to provide an online hot riveting equipment and method for automotive lighting components, which has the advantages of saving hot riveting cycle time, good hot riveting consistency, and meeting the hot riveting requirements of high load.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An online hot riveting equipment for automotive lighting components includes: an equipment frame and a hot riveting station and a riveting point detection station arranged sequentially on the equipment frame for riveting. A multiplier chain assembly for the transfer of lighting products is installed on the equipment frame. A tooling tray for clamping the lighting products is slidably disposed on the multiplier chain assembly. The hot riveting station includes upper and lower main cylinders and a hot riveting upper die for riveting the lighting products. The upper and lower main cylinders drive the hot riveting upper die to move up and down. A lifting module is disposed below the multiplier chain assembly, located directly below the hot riveting upper die. The riveting point detection station includes a vision inspection module.

[0007] The lifting module includes a second support plate, a roller assembly, and a lifting cylinder. The moving end of the lifting cylinder moves horizontally, and a wedge-shaped top block is provided on the moving end of the lifting cylinder. An inclined surface is formed on the wedge-shaped top block. One end of the roller assembly is connected to the lower end of the second support plate, and the other end of the roller assembly can roll along the inclined surface of the wedge-shaped top block. The tooling pallet is disposed on the second support plate. The lifting cylinder drives the wedge-shaped top block to move horizontally, thereby driving the roller assembly to roll along the inclined surface, and thus driving the second support plate to move up and down to realize the lifting or lowering of the tooling pallet.

[0008] The specific technical effects are as follows: The multiplier chain assembly provides power to facilitate the flow of lighting products, saving manual handling time and improving production cycle time. By setting up a lifting module, when the tooling pallet moves to the bottom of the hot riveting upper die, the lifting module can lift the tooling pallet and lighting products from the multiplier chain assembly. The position of the lifting module allows for secondary positioning of the lighting products, effectively improving riveting consistency and preventing the hot riveting upper die from damaging the chain during the downward pressing process. The lifting cylinder's horizontal movement, combined with the wedge-shaped top block and roller assembly, converts the horizontal movement of the lifting cylinder into the vertical movement of the second support plate, thereby achieving the lifting and lowering of the tooling pallet and lighting products. This design avoids the force from directly acting on the cylinder during the downward pressing process of the hot riveting upper die, preventing the cylinder from being unable to withstand long-term, high-pressure operations. Furthermore, this design provides better support for the vertically moving second support plate, further improving the accuracy of secondary positioning and ensuring riveting consistency.

[0009] Furthermore, the lifting module also includes a mounting plate and a first support plate. The lifting cylinder is mounted on the mounting plate, and the first support plate is connected to the moving end of the lifting cylinder. The wedge-shaped top block is mounted on the first support plate, and an inclined lifting guide groove is formed on the wedge-shaped top block. The inclined surface is formed at the bottom of the lifting guide groove. The roller assembly includes a roller mounting frame mounted on the second support plate and a roller mounted on the lower end of the roller mounting frame. The roller is rotatably connected to the roller mounting frame through a bearing. The roller is rotatably disposed in the lifting guide groove. The tooling pallet is disposed on the second support plate. The lifting cylinder drives the first support plate and the wedge-shaped top block to move horizontally, thereby driving the roller to reciprocate along the lifting guide groove, and thus driving the second support plate to move up and down to realize the lifting or lowering of the tooling pallet.

[0010] Furthermore, the lifting module also includes a support base mounted on the equipment frame, a horizontal linear guide rail arranged on the mounting plate in the horizontal direction, a cylindrical pin, a diamond pin, and several support columns mounted on the upper surface of the second support plate. The cylindrical pin, the diamond pin, and the several support columns can all operably lift the tooling pallet. The mounting plate is disposed on the support base, and the mounting plate is provided with a lifting flange linear bushing. The lower end of the lifting guide shaft is slidably connected to the lifting flange linear bushing, and the upper end of the lifting guide shaft is mounted on the second support plate. The first support plate is slidably mounted on the horizontal linear guide rail via a lifting slider.

[0011] The specific technical effect is as follows: the moving end of the lifting cylinder moves horizontally, driving the first support plate and the wedge-shaped top block to move along the horizontal linear guide rail. Because the wedge-shaped top block has an inclined lifting guide groove, as the wedge-shaped top block moves to the right, the roller gradually climbs along the lifting guide groove, so the second support plate gradually rises. This structural design converts the horizontal movement of the cylinder into the vertical movement of the second support plate, which can not only withstand a large load but also has high positioning accuracy. The cylindrical pin and the diamond pin abut against the lower end of the tooling tray. After the second support plate is raised to the position, the tooling tray leaves the multiplier chain assembly. Several support columns can also evenly support the tooling tray, solving the problem of the hot riveting upper mold damaging the chain during the pressing process.

[0012] Furthermore, the hot riveting station also includes a hot riveting frame. A control panel is mounted on the equipment frame. The hot riveting frame includes a mold base plate mounted on the control panel, four upper mold guide shafts with both ends connected to guide flanges at the four corners of the mold base plate and the four corners of the mold top plate, flanged linear bushings fitted onto the upper mold guide shafts, a pulse hot riveting intermediate frequency unit mounted on the mold top plate, and a cable protection chain mounted on the mold top plate. The upper and lower main cylinders are mounted on the mold top plate. A floating joint is provided on the moving end of the die. The lower end of the floating joint is connected to the movable plate. The four corners of the movable plate are connected to the flanged linear bushing. The movable plate is moved up and down along the upper die guide shaft between the die base plate and the die top plate. An upper guide groove is provided on both ends of the lower end face of the movable plate. The two ends of the hot riveting upper die are inserted into the upper guide groove. A clamping bushing is provided on the movable plate. A rotating plunger that cooperates with the clamping bushing is provided on the hot riveting upper die. The rotating plunger is inserted into the clamping bushing.

[0013] The specific technical effects are as follows: the hot riveting upper mold can be installed in the upper guide groove along the extension direction of the upper guide groove, and is quickly inserted into the fixture bushing by rotating the plunger. This detachable design allows for quick replacement, and the hot riveting upper mold can be replaced with other mold structures according to actual needs, such as: pressing structure, airtight electrical inspection structure, glue coating and pressing structure, etc. Different mold structures can meet different assembly requirements of lamps; the extension and retraction of the moving ends of the upper and lower main cylinders can drive the movable plate to move between the mold base plate and the mold base plate, thereby realizing the lifting and lowering of the hot riveting upper mold; the pulse hot riveting intermediate frequency is used to control the temperature and frequency of pulse hot riveting.

[0014] Furthermore, the hot riveting upper mold includes an upper template, four tooling guide pillars all mounted on the lower end face of the upper template via a first flange fixing seat, a pneumatic and electrical mounting seat mounted on the upper template, a tolerance combination seat mounted on the upper end of the pneumatic and electrical mounting seat, and upper and lower hot riveting structures, bevel hot riveting structures, and side hot riveting structures for riveting the lighting products. The upper and lower hot riveting structures, the bevel hot riveting structures, and the side hot riveting structures are all mounted on the lower end face of the upper template.

[0015] Furthermore, the upper and lower hot riveting structure includes a cylinder mounting base, a vertical hot riveting cylinder disposed at the lower end of the cylinder mounting base, a first connecting plate disposed on the moving end of the vertical hot riveting cylinder, and both the vertical hot riveting head and the vertical hot riveting gun are disposed below the first connecting plate through a vertical riveting gun mounting base, and the buffer is disposed below the first connecting plate through a buffer mounting base.

[0016] The side hot riveting structure includes a connecting plate I, a connecting plate II, a cylinder seat I, a cylinder seat II, a slide cylinder I, a connecting plate III, a pre-compression structure, a cylinder seat III, a connecting block II, a support cylinder, and a support block. The connecting plate II is mounted on the connecting plate I via several first profiles. The cylinder seat I is mounted on the connecting plate II, and the extending direction of the cylinder seat I forms a first angle with the horizontal plane. The cylinder seat II is mounted on the cylinder seat I, and the slide cylinder I is mounted on the cylinder seat II. The moving end of the slide cylinder I moves along the extending direction of the cylinder seat I. The connecting plate III is disposed on the moving end of the slide cylinder I. The upper end of the pre-pressing structure is disposed on the connecting plate III. The lower end of the pre-pressing structure is movably abutted against the lamp product. The hot riveting head I and the hot riveting gun I are both disposed on the connecting plate III through the riveting gun mounting seat I. The cylinder seat III is disposed on the connecting plate III. The connecting block II is disposed on the cylinder seat III. The supporting cylinder is disposed on the connecting block II. The supporting block is disposed on the rotating end of the supporting cylinder. The connecting plate II is provided with a pressure regulating valve for controlling the air pressure when the hot riveting gun I extends.

[0017] The inclined hot riveting structure includes a cylinder seat IV, a slide cylinder II, a connecting plate IV, and a pre-pressing structure. The slide cylinder II is disposed on the cylinder seat IV. The extension direction of the cylinder seat IV has a second included angle with the horizontal plane. The moving end of the slide cylinder II moves in a direction perpendicular to the extension direction of the cylinder seat IV. The connecting plate IV is disposed on the moving end of the slide cylinder II. The upper end of the pre-pressing structure is disposed on the connecting plate IV. The lower end of the pre-pressing structure is movably abutted against the lighting product. The hot riveting head II and the hot riveting gun II are disposed on the connecting plate IV.

[0018] The specific technical effects are as follows: the vertical hot riveting cylinder's moving end moves up and down, causing the buffer, vertical hot riveting head, and vertical hot riveting gun to rise and fall. The vertical hot riveting head is used to rivet the lighting products, the vertical hot riveting gun is used to blow air to cool the riveted parts after hot riveting, and the buffer is used to prevent the lighting products from being lifted by the hot riveting gun after hot riveting. The extension direction of cylinder seat I has a first angle with the horizontal plane, cylinder seat II is set at the tail end of cylinder seat I, and the movement direction of the moving end of the slide cylinder I is the same as the extension direction of cylinder seat I. If they are aligned, the hot riveting head I and the hot riveting gun I can be driven to rivet the side of the lighting product. The support cylinder is a rotary clamping cylinder, and the support block is installed on the rotating end of the support cylinder to support the suspended part of the lighting product during hot riveting. The extension direction of the cylinder seat IV has a second included angle with the horizontal plane. The slide cylinder II is set at the lower end of the cylinder seat IV. The movement direction of the moving end of the slide cylinder II is perpendicular to the extension direction of the cylinder seat IV, which can drive the hot riveting head II and the hot riveting gun II to rivet the inclined side of the lighting product.

[0019] Furthermore, the pre-compression structure includes a pre-compression seat, a connecting block I, a linear guide rail, a pre-compression slider, a pre-compression limiting rod, a spring, and a pressure block. The pre-compression seat is mounted on the connecting plate III or the connecting plate IV. The connecting block I and the linear guide rail are both disposed on the pre-compression seat. The linear guide rail is located below the connecting block I. The pre-compression slider is slidably connected to the linear guide rail. The lower end of the pre-compression limiting rod is connected to the pre-compression slider, and the upper end of the pre-compression limiting rod passes through the connecting block I. The spring is sleeved on the outside of the pre-compression limiting rod, and both ends of the spring abut against the connecting block I and the pre-compression slider, respectively. The pressure block is disposed on the pre-compression slider and is used to abut against the lighting product.

[0020] The specific technical effect is as follows: when the pressure block comes into contact with the lighting product, the pre-pressure slider will slide on the linear guide rail, which will cause the pressure block to rise. However, the elastic force of the spring will rebound, allowing the pressure block to press better on the lighting product. This ensures both the stability of the pressing and the elasticity when it first comes into contact with the lighting product, preventing damage to the surface of the lighting product due to hard pressure.

[0021] Furthermore, the visual inspection module includes a robotic arm mounted on the equipment frame, a light source mounting base and a second camera mounting base mounted on the lower end of the robotic arm via a robotic arm mounting base, a second light source disposed on the light source mounting base, a second camera disposed on the second camera mounting base, a third profile disposed on the equipment frame, a first connecting rod disposed on the upper end of the third profile, a second connecting rod disposed on the first connecting rod via a connecting block III, a first camera disposed on the front end of the second connecting rod via a first camera mounting base, and a first light source disposed on the first camera mounting base via a light source connecting plate.

[0022] The specific technical effect is as follows: the first light source and the first camera are used to detect the rivets on the side of the lighting product, while the second light source and the second camera are used to detect the rivets of the entire lighting product through the movement of the robotic arm.

[0023] Furthermore, the multiplier chain assembly includes a multiplier chain mounting block and a multiplier chain. The multiplier chain is mounted on the equipment frame via the multiplier chain mounting block. The tooling tray includes a tray slidably connected to the multiplier chain, four tooling lower guide posts, and a tooling support plate. The four tooling lower guide posts are mounted on the four corners of the tray via second flange fixing seats. The tooling support plate is mounted on the tray via a second profile. The tooling support plate is provided with a product limiting block for fixing the lighting product.

[0024] The specific technical effect is that by installing the pallet on the multi-chain conveyor, the lighting products can be moved by the multi-chain conveyor, saving the time of manual handling.

[0025] A method for online hot riveting of automotive lighting components, comprising using an online hot riveting equipment for automotive lighting components as described in any one of the above claims to perform hot riveting on the lighting product, wherein the method includes the following steps:

[0026] Step S1: Install the hot riveting upper die on the movable plate. The two ends of the hot riveting upper die are installed in the upper guide groove, and the hot riveting upper die is locked by inserting the rotating plunger into the fixture bushing.

[0027] Step S2: Place the lighting product to be riveted on the product limiting block, and the tray with the lighting product installed will be moved to the top of the lifting module under the drive of the multiplier chain.

[0028] Step S3: Start the lifting cylinder. The moving end of the lifting cylinder extends horizontally, driving the first support plate and the wedge-shaped top block to move on the horizontal linear guide rail. The roller gradually climbs along the lifting guide groove of the wedge-shaped top block, driving the second support plate to gradually lift upward, so that the cylindrical pin and the diamond pin abut against the lower end of the tray, and several support columns also abut against the lower end of the tray. After the second support plate is lifted into place, the tray leaves the multiplier chain.

[0029] Step S4: Start the upper and lower main cylinders. The moving ends of the upper and lower main cylinders extend and drive the movable plate and the hot riveting upper mold to descend until the upper guide post of the tooling and the lower guide post of the tooling close together.

[0030] Step S5: Activate the vertical hot riveting cylinder. The moving end of the vertical hot riveting cylinder extends, driving the first connecting plate, vertical hot riveting head, vertical hot riveting gun, and buffer downwards. The vertical hot riveting head rivets the upper end of the lighting product. After hot riveting, the vertical hot riveting gun blows air to cool the riveted area. The buffer is used to prevent the lighting product from being lifted by the hot riveting gun after hot riveting. Simultaneously, activate the slide cylinder I. The moving end of the slide cylinder I extends, driving the connecting plate III, pre-pressure structure, hot riveting head I, hot riveting gun I, and cylinder seat III to move towards the side of the lighting product. When the pressure block contacts the lighting product, the pre-pressure slider will slide on the linear guide rail. When the spring moves, it lifts the pressure block, but the spring's elastic force rebounds, allowing the pressure block to press more firmly onto the lighting product. Then, the support cylinder is activated, and its rotating end rotates the support block into place, supporting the suspended part of the lighting product. The hot riveting head I rivets the side of the lighting product. After the hot riveting is completed, the hot riveting gun I blows air to cool the riveted area. At the same time, the sliding cylinder II is activated, and its moving end extends, causing the connecting plate IV, the pre-pressing structure, the hot riveting head II, and the hot riveting gun II to move towards the inclined side of the lighting product. The hot riveting head II rivets the inclined side of the lighting product. After the hot riveting is completed, the hot riveting gun II blows air to cool the riveted area.

[0031] Step S6: After the riveting in step S5 is completed, the moving end of the vertical hot riveting cylinder, the moving end of the slide cylinder I, and the moving end of the slide cylinder II all retract to their original positions. Then the moving ends of the upper and lower main cylinders also retract, driving the movable plate and the hot riveting upper mold to rise and reset.

[0032] Step S7: The moving end of the lifting cylinder retracts, causing the first support plate and the wedge-shaped top block to move on the horizontal linear guide rail. The roller gradually descends along the lifting guide groove of the wedge-shaped top block, causing the second support plate to gradually descend. After the second support plate descends to its position, the support column, cylindrical pin and diamond pin leave the lower end of the tray, and the tray is placed back on the multiplier chain.

[0033] Step S8: Driven by the multiplier chain, the tray continues to flow to the bottom of the vision inspection module. The first light source and the first camera detect the rivets on the side of the lighting product. At the same time, through the movement of the robotic arm, the second light source and the second camera detect the rivets of the entire lighting product.

[0034] Step S9: Complete the riveting inspection of the entire lighting product.

[0035] The beneficial effects of this invention are:

[0036] (1) The power of the multiplier chain component is used to realize the flow of lighting products, which saves the time of manual handling and improves the production cycle. By setting up the lifting module, when the tooling pallet flows to the bottom of the hot riveting upper mold, the lifting module can lift the tooling pallet and lighting products from the multiplier chain component. The position of the lifting module can be used to perform secondary positioning of the lighting products, which can effectively improve the consistency of riveting and prevent the hot riveting upper mold from crushing the chain during the pressing process.

[0037] (2) The lifting cylinder moves horizontally, and with the help of the wedge block and roller assembly, the horizontal movement of the lifting cylinder is converted into the vertical movement of the second support plate, thereby realizing the lifting and lowering of the tooling tray and lighting products. This design can avoid the force of the hot riveting upper mold acting directly on the cylinder during the pressing process, which would cause the cylinder to be unable to withstand long-term, high-pressure operation. On the other hand, this design can provide better support for the vertically moving second support plate, further improve the accuracy of secondary positioning, and ensure the consistency of riveting.

[0077] See Figure 7 As shown, the slide cylinder II 622-2 is mounted on the cylinder seat IV 622-1. The moving end of the slide cylinder II 622-2 is connected to the connecting plate IV 622-3. The preload seat 71 is mounted on the connecting plate IV 622-3. The hot riveting head II 622-4 and the hot riveting gun II 622-5 are mounted on the connecting plate IV 622-3.

[0078] See Figure 8 As shown, the preload seat 71 is installed on the connecting plate Ⅲ623-6 or the connecting plate Ⅳ622-3. The connecting block Ⅰ72 and the linear guide rail 73 are both set on the preload seat 71. The linear guide rail 73 is located below the connecting block Ⅰ72. The preload slider 74 is slidably connected to the linear guide rail 73. The lower end of the preload limiting rod 75 is connected to the preload slider 74, and the upper end of the preload limiting rod 75 passes through the connecting block Ⅰ72. The spring 76 is sleeved on the outside of the preload limiting rod 75, and the two ends of the spring 76 abut against the connecting block Ⅰ72 and the preload slider 74 respectively. The pressure block 77 is set on the pre-pressure slider 74. The pressure block 77 is used to press against the lighting product. The pressure block 77 can change the pressing shape of its end according to different product shapes. When the pressure block 77 contacts the lighting product, the pre-pressure slider 74 will slide on the linear guide rail 73, which will drive the pressure block 77 to rise. However, the elastic force of the spring 76 will rebound, which will make the pressure block 77 press better on the lighting product. This ensures both the stability of the pressing and the elasticity when it first contacts the lighting product, so as not to damage the surface of the lighting product due to hard pressing.

[0080] See Figure 10 As shown, there are two support seats 517, which are arranged in a Z-shape. The two support seats 517 are respectively installed on both ends of the mounting plate 512. The lifting cylinder 513 and four horizontally mounted on the mounting plate 512. The moving end of the lifting cylinder 513 moves to the right, pushing the first support plate 514 to move to the right. One end of the four lifting guide shafts 523 is connected to the four corners of the second support plate 511. The other end of the lifting guide shafts 523 passes through the four lifting flange linear bushings 522 installed on the mounting plate 512. The cylindrical pins 519 and the diamond pins 520 are respectively installed at both ends of the second support plate 511. Six support columns 521 are installed on the second support plate 511. Four roller mounting brackets 525 are installed at the four corners of the lower end of the second support plate 511. Each roller 526 is connected to the roller mounting bracket 525 through a bearing 527. This structure converts the horizontal movement of the cylinder into the vertical movement of the second support plate 511, which can not only withstand a large load but also has high positioning accuracy.

[0081] See Figure 12 As shown, after the product is hot-riveted, the tray 41 continues to flow under the vision inspection module 8 driven by the multiplier chain 32 for visual inspection of the rivet points. Two third profiles 87 are installed on the table panel 2, the first connecting rod 88 is installed on the third profile 87, and two second connecting rods 90 are installed on the first connecting rod 88 through the connecting block Ⅲ 89. Two first cameras 92 are respectively installed on the two second connecting rods 90 through the two first camera 92 mounting seats 91. Each first light source 94 is installed on a first camera 92 mounting seat 91 through the light source connecting plate 93. This structural design is used to detect the rivet points on the side of the lighting product. Two second cameras 86 are respectively installed on the two second camera 86 mounting seats 84, and two second light sources 85 are installed on the two light source mounting seats 83. The two light source mounting seats 83 and the two second camera 86 mounting seats 84 are all connected to the robot arm 81 through the robot arm 81 mounting seat. The upper end of the robot arm 81 is installed on the equipment frame 1. The rivet points of the entire product can be detected by the movement of the robot arm 81.

[0082] See Figure 14 As shown, the extension direction of cylinder seat I623-3 has a first angle with the horizontal plane, the angle of which is 21°. The movement direction of the moving end of the slide cylinder I623-5 is as follows. Figure 14 As indicated by the middle arrow.

[0083] See Figure 15 As shown, the extension direction of cylinder seat Ⅳ622-1 has a second included angle with the horizontal plane, the angle of which is 5°. The movement direction of the moving end of slide cylinder Ⅱ622-2 is as follows. Figure 15 As indicated by the middle arrow.

[0084] The specific operation steps of this invention are as follows:

[0085] Step S1: Install the hot riveting upper die 62 on the movable plate 612. The two ends of the hot riveting upper die 62 are installed in the upper guide groove 612-1, and the hot riveting upper die 62 is locked by quickly inserting the rotating plunger 612-3 into the clamp bushing 612-2.

[0086] Step S2: Place the lamp product to be riveted on the product limiting block 46. The tray 41 with the lamp product installed is driven by the multiplier chain 32 according to... Figure 1 The direction indicated by the middle arrow flows to the top of the lifting module 5;

[0087] Step S3: Start the lifting cylinder 513. The moving end of the lifting cylinder 513 extends horizontally, driving the first support plate 514 and the wedge-shaped top block 515 to move on the horizontal linear guide rail 518. The roller 526 gradually climbs along the lifting guide groove 516 of the wedge-shaped top block 515, driving the second support plate 511 to gradually rise, so that the cylindrical pin 519 and the diamond pin 520 abut against the lower end of the tray 41, and several support columns 521 also abut against the lower end of the tray 41. After the second support plate 511 is lifted into place, the tray 41 leaves the multiplier chain 32.

[0088] Step S4: Start the upper and lower main cylinders 611. The moving end of the upper and lower main cylinders 611 extends and drives the movable plate 612 and the hot riveting upper mold 62 to descend until the upper guide post 625 of the tooling and the lower guide post 42 of the tooling close together.

[0089] Step S5: Activate the vertical hot riveting cylinder 621-2. The moving end of the vertical hot riveting cylinder 621-2 extends, driving the first connecting plate 621-3, vertical hot riveting head 621-4, vertical hot riveting gun 621-5, and buffer 621-7 downwards. The vertical hot riveting head 621-4 rivets the upper end of the lamp product. After the hot riveting is completed, the vertical hot riveting gun 621-5 blows air to cool the riveted part. The buffer 621-7 is used to prevent the lamp product from being lifted by the hot riveting gun after the hot riveting is completed. At the same time, activate the slide cylinder I 623-5. The moving end of the slide cylinder I 623-5 extends, driving the connecting plate III 623-6, pre-pressure structure 7, hot riveting head I 623-12, hot riveting gun I 623-13, and cylinder seat III 623-7 to move towards the side of the lamp product. When the pressure block 77 contacts the lamp product, because the pre-pressure slider 74 will be in the vertical direction... The sliding of the guide rail 73 causes the pressure block 77 to rise. However, the elastic force of the spring 76 rebounds, allowing the pressure block 77 to press better onto the lighting product. Then, the support cylinder 623-9 is activated. The rotating end of the support cylinder 623-9 drives the support block 623-10 to rotate into place and support the suspended part of the lighting product. The hot riveting head I 623-12 rivets the side of the lighting product. After the hot riveting is completed, the hot riveting gun I 623-13 blows air to cool the riveted part. At the same time, the sliding cylinder II 622-2 is activated. The moving end of the sliding cylinder II 622-2 extends and drives the connecting plate IV 622-3, the pre-pressing structure 7, the hot riveting head II 622-4, and the hot riveting gun II 622-5 to move towards the inclined side of the lighting product. The hot riveting head II 622-4 rivets the inclined side of the lighting product. After the hot riveting is completed, the hot riveting gun II 622-5 blows air to cool the riveted part.

[0090] Step S6: After the riveting in step S5 is completed, the moving ends of the vertical hot riveting cylinder 621-2, the moving ends of the slide cylinder I 623-5 and the moving ends of the slide cylinder II 622-2 are all retracted back to their original positions. Then the moving ends of the upper and lower main cylinders 611 are also retracted, which drives the movable plate 612 and the hot riveting upper mold 62 to rise and reset.

[0091] Step S7: The moving end of the lifting cylinder 513 retracts, causing the first support plate 514 and the wedge-shaped top block 515 to move on the horizontal linear guide rail 518. The roller 526 gradually descends along the lifting guide groove 516 of the wedge-shaped top block 515, causing the second support plate 511 to gradually descend. After the second support plate 511 descends to its position, the support column 521, the cylindrical pin 519 and the diamond pin 520 leave the lower end of the tray 41, and the tray 41 is placed back on the multiplier chain 32.

[0092] In step S8, the tray 41 continues to flow under the vision inspection module 8 under the drive of the multiplier chain 32. The first light source 94 and the first camera 92 are used to inspect the rivets on the side of the lamp product. At the same time, the second light source 85 and the second camera 86 are used to inspect the rivets of the entire lamp product through the movement of the robot arm 81.

[0093] Step S9: Complete the riveting inspection of the entire lighting product.

[0094] In summary, the beneficial effects of this invention are:

[0095] (1) The power provided by the multiplier chain component 3 enables the flow of lighting products, saving the time of manual handling and improving the production cycle. By setting up the lifting module 5, when the tooling pallet 4 flows to the bottom of the hot riveting upper mold 62, the lifting module 5 can lift the tooling pallet 4 and the lighting products from the multiplier chain component 3. The position of the lifting module 5 can be used to perform secondary positioning of the lighting products, which can effectively improve the consistency of riveting and prevent the hot riveting upper mold 62 from damaging the chain during the downward pressing process.

[0096] (2) The lifting cylinder 513 moves horizontally, and with the help of the wedge-shaped top block 515 and roller 526 assembly, the horizontal movement of the lifting cylinder 513 is converted into the vertical movement of the second support plate 511, thereby realizing the lifting and lowering of the tooling tray 4 and the lighting products. This design can avoid the force of the hot riveting upper mold 62 acting directly on the cylinder during the pressing process, which would cause the cylinder to be unable to withstand long-term, high-pressure operation. On the other hand, this design can improve the support of the vertically moving second support plate 511, further improve the accuracy of secondary positioning, and ensure the consistency of riveting.

The moving end of the vertical hot riveting cylinder (621-2) extends, driving the first connecting plate (621-3), vertical hot riveting head (621-4), vertical hot riveting gun (621-5), and buffer (621-7) downwards. The vertical hot riveting head (621-4) rivets the upper end of the lamp product. After the hot riveting is completed, the vertical hot riveting gun (621-5) blows air to cool the riveted part. The buffer (621-7) uses... To prevent the lighting fixture from being lifted by the riveting gun after the riveting process is completed; simultaneously, the sliding cylinder I (623-5) is activated, and the moving end of the sliding cylinder I (623-5) extends to drive the connecting plate III (623-6), the pre-pressing structure (7), the riveting head I (623-12), the riveting gun I (623-13), and the cylinder seat III (623-7) to move towards the side of the lighting fixture. When the pressure block (77) contacts the lighting fixture, because the pre-pressing slider (74) will... The linear guide (73) slides, which causes the pressure block (77) to rise. However, the elastic force of the spring (76) rebounds, which makes the pressure block (77) press better onto the lamp product. Then the support cylinder (623-9) is activated. The rotating end of the support cylinder (623-9) drives the support block (623-10) to rotate into place and support the suspended part of the lamp product. The hot riveting head I (623-12) rivets the side of the lamp product. After the hot riveting is completed, the hot riveting gun I (623-12) rivets the side of the lamp product. -13) Cool the hot riveting part with air; at the same time, start the slide cylinder II (622-2), the moving end of the slide cylinder II (622-2) extends and drives the connecting plate IV (622-3), the pre-pressing structure (7), the hot riveting head II (622-4) and the hot riveting gun II (622-5) to move towards the inclined side of the lamp product. The hot riveting head II (622-4) rivets the inclined side of the lamp product. After the hot riveting is completed, the hot riveting gun II (622-5) cools the hot riveting part with air. Step S6: After the riveting in step S5 is completed, the moving ends of the vertical hot riveting cylinder (621-2), the moving ends of the slide cylinder I (623-5), and the moving ends of the slide cylinder II (622-2) are all retracted to their original positions. Then the moving ends of the upper and lower main cylinders (611) are also retracted, driving the movable plate (612) and the hot riveting upper mold (62) to rise and reset. Step S7: The moving end of the lifting cylinder (513) retracts, causing the first support plate (514) and the wedge-shaped top block (515) to move on the horizontal linear guide rail (518). The roller (526) gradually descends along the lifting guide groove (516) of the wedge-shaped top block (515), causing the second support plate (511) to gradually descend. After the second support plate (511) descends to its position, the support column (521), the cylindrical pin (519) and the diamond pin (520) leave the lower end of the tray (41), and the tray (41) is placed back on the multiplier chain (32). In step S8, the tray (41) continues to flow under the vision inspection module (8) driven by the multiplier chain (32). The first light source (94) and the first camera (92) are used to detect the rivets on the side of the lamp product. At the same time, the second light source (85) and the second camera (86) are used to detect the rivets of the entire lamp product through the movement of the robot arm (81). Step S9: Complete the riveting inspection of the entire lighting product.
