Technical Field
[0001] This invention belongs to the field of automotive lighting coating technology, specifically an automatic conveying mechanism for a new energy vehicle automotive lighting coating production line. Background Technology
[0002] New energy vehicle headlight coating is a key process in automotive parts manufacturing, aiming to give headlights an aesthetically pleasing appearance, protect the housing material, and meet functional requirements such as weather resistance and optics. New energy vehicle headlight coating includes a pre-treatment stage, namely surface cleaning and surface activation treatment. This process requires loading the new energy vehicle headlights into a tooling basket for transport by a suspended conveyor chain. When using a suspended conveyor chain to transport the headlights of new energy vehicles during the painting process, traditional suspended conveyor chains require regular lubrication with a large amount of lubricating oil. As a result, the lubricating oil is prone to accumulate and drip, contaminating the headlights and the pretreatment tank liquid. Furthermore, the traditional suspended conveyor chain or track is inevitably squeezed and friction will generate metal particles, and dust will easily accumulate over time. If metal particles or dust fall onto the headlights or into the pretreatment tank liquid, it will also affect subsequent processes. In view of this, the present invention proposes an automatic conveying mechanism for a new energy vehicle headlight coating production line to solve the above-mentioned technical problems. Summary of the Invention
[0003] To overcome the shortcomings of existing technologies, this invention uses the mutual repulsion of like-pole magnetic forces to reduce the friction and compression of the internal load-bearing components on the conveyor track due to gravity, thereby reducing wear on the internal load-bearing components and the conveyor track, and thus reducing the generation of metal shavings. It also reduces lubrication requirements and reduces the accumulation and dripping of lubricating oil. This invention provides an automatic conveying mechanism for a new energy vehicle headlight coating production line.
[0004] The technical solution adopted by this invention to solve its technical problem is: an automatic conveying mechanism for a new energy vehicle headlight painting production line, comprising: a hook, wherein the new energy vehicle headlight is suspended below the hook via a tooling basket; the automatic conveying mechanism for the new energy vehicle headlight painting production line further comprises: an anti-pollution unit, wherein the anti-pollution unit includes a conveying track, and the anti-pollution unit reduces the friction and compression of the conveying track by the internal load-bearing components under the influence of gravity by using the mutual repulsion of like pole magnetic forces, thereby reducing the wear of the internal load-bearing components and the conveying track, thereby reducing the generation of metal shavings, and also reducing the lubrication requirements and reducing the accumulation and dripping of lubricating oil; the cross-section of the conveying track is semi-enclosed, which can block impurities and lubricating oil, effectively reducing the dripping of impurities and lubricating oil, and reducing the impact on subsequent processes.
[0005] Preferably, the anti-pollution unit includes: a permanent magnet, the cross-section of the conveying track is in the shape of the Chinese character "si" and the central position at the bottom is permeable; a number of permanent magnets are fixedly laid on both sides near the central part of the bottom of the conveying track; a sliding block, on both sides inside the conveying track, there are first grooves, and a number of sliding blocks are evenly slidably connected in each first groove, the top of each sliding block coincides with the top of the first groove, and the bottom of each sliding block is flush with the inner bottom of the conveying track; a first block, a first block is slidably connected to each sliding block, the sliding blocks on both sides of the conveying track correspond to each other in position and are grouped in pairs, the first blocks on each group of sliding blocks are jointly fixedly connected to a second block, the second block is located at the central part of the conveying track and a hook is arranged at the bottom; the bottom of each first block corresponds to the position of the permanent magnet and a first electromagnet is fixedly arranged, when the first electromagnet is powered on, it repels the permanent magnet; a first gear, a driving motor is arranged at a position near the bottom inside each sliding block, the output shafts of the driving motors are jointly fixedly connected to first gears, and a first rack is fixedly connected to a position near the bottom of the side wall of each first groove, and the first gear meshes with the corresponding first rack.
[0006] Preferably, a first cavity is opened inside the second block, a conductive plate is fixedly connected to one side wall of the first cavity, a resistance plate is fixedly connected to the other side wall of the first cavity, the bottom of the resistance plate is connected to the control circuit of the first electromagnet, a power connection plate is slidably connected inside the first cavity, the power connection plate contacts the conductive plate and the resistance plate, a hook is fixedly connected to the bottom of the power connection plate, and a first spring is fixedly connected between the bottom of the power connection plate and the bottom of the first cavity; the conductive plate is connected to the power supply; The vehicle lamp is suspended below the hook through a tooling hanging basket to enter the pretreatment stage of painting. At this time, the first electromagnet is powered on and repels the permanent magnet, so that the first block lifts the second block, thereby offsetting the pulling force of the vehicle lamp on the hook. The first block can slide freely relative to the sliding block. The magnetic force of the first electromagnet can be set. Preferably, the repulsive force between the first electromagnet and the permanent magnet is exactly equal to the gravity of the vehicle lamp in the tooling hanging basket, so that the end of the first block is in a suspended state in the sliding groove of the sliding block; then the driving motor drives the first gear to rotate, and配合 the first rack, so that the sliding block can walk relative to the conveying track. In this way, the friction is reduced, the wear is reduced, and the generation of metal particles is reduced. At the same time, the lubrication requirement is reduced; the power supply, the conductive plate, the power connection plate, and the resistance plate jointly form the control circuit of the first electromagnet. When the vehicle lamp in the tooling hanging basket is heavier, the hook moves downward, that is, the power connection plate moves downward. Similar to the principle of a sliding rheostat, the shorter the resistance plate connected to the circuit, the smaller the resistance value, that is, the larger the current flowing into the first electromagnet, and the larger the magnetic force of the first electromagnet. Therefore, it can be made that the magnetic force of the first electromagnet changes with the gravity below the hook, and it can adapt to multiple weight modes as much as possible to reduce friction.
[0007] Preferably, a brush is rotatably connected to the bottom of each of the first gears, and the brush matches the bottom of the first groove.
[0008] Preferably, the bottom of the first trough is provided with a plurality of dust collection holes, each of the dust collection holes penetrating the bottom of the conveying track, and a dust collection cylinder is threadedly connected to the bottom of the conveying track at a position corresponding to each dust collection hole; The bottom of the No. 1 trough is lower than the bottom of the conveyor track, and the wear of the No. 1 gear and the No. 1 rack also easily produces metal particles, which tend to accumulate at the bottom of the No. 1 trough. Therefore, when the sliding block moves, it drives the No. 1 brush to move at the bottom of the No. 1 trough, scraping the impurities into the dust collection hole, and then into the dust collection cylinder to complete the collection of impurities, reducing the impact of impurities falling on the process. The dust collection cylinder is a threaded connection that can be disassembled and can be disassembled periodically to treat the impurities.
[0009] Preferably, a fixed rod is fixedly connected between each pair of sliding blocks in each of the first slots. The fixed rod is close to the bottom of the conveying track. A scraper plate is fixedly connected to each fixed rod near the center. The bottom of the scraper plate is in contact with the bottom of the conveying track.
[0010] Preferably, each scraper plate has a second cavity on one side near the center of the conveying track. A first bevel gear is rotatably connected to the side wall of the second cavity. A second bevel gear is rotatably connected to the top of the second cavity, and a third bevel gear is rotatably connected to the bottom of the second cavity. The first, second, and third bevel gears mesh with each other. The second bevel gear is fixedly connected to a first shaft. The first shaft is rotatably connected to the scraper plate and its top extends through the top of the scraper plate. A pulley is fixedly connected to the top of the first shaft. The third bevel gear is fixedly connected to the second shaft. The second shaft passes through the first bevel gear, the first shaft, and the pulley and is rotatably connected to the first bevel gear, the first shaft, and the pulley. A contact wheel is fixedly connected to the top of the second shaft. The contact wheel is located above the pulley and contacts the side wall of the conveying track near the center. A pulley is rotatably connected to the top of the other side of the scraper plate. A first belt is fitted between the two pulleys at the top of the scraper plate. Several second brushes are fixedly connected to the bottom of the first belt. Dust inevitably accumulates over time in the area from the first trough to the center of the conveyor track. The shape of the conveyor track effectively prevents impurities from falling. As the sliding block advances, the scraper scrapes away the dust in this area. The contact wheel contacts the inner wall of the conveyor track, causing it to rotate. Because the first, second, and third bevel gears mesh with each other, the pulley rotates in the opposite direction, driving the first belt to rotate. This causes the second brush to move. The reverse rotation of the pulley ensures that the second brush moves in a direction that sweeps the impurities collected by the scraper into the first trough. As the sliding block advances, the scraper collects the impurities, and then the second brush sweeps them into the first trough. The impurities enter the first trough, are brushed by the first brush, and then enter the dust collection cylinder for easy cleaning and collection. The first rack is embedded in the side wall of the first trough, so there is no need to worry about impurities swept by the second brush falling onto the first rack.
[0011] The beneficial effects of this invention are as follows: 1. The automatic conveying mechanism of the new energy vehicle headlight coating production line of the present invention includes an anti-pollution unit. The anti-pollution unit includes a conveying track. The anti-pollution unit reduces the friction and compression of the conveying track caused by gravity on the internal load-bearing components by mutual repulsion of like-pole magnetic forces, thereby reducing the wear of the internal load-bearing components and the conveying track, and thus reducing the generation of metal shavings. It also reduces the lubrication requirements and reduces the accumulation and dripping of lubricating oil. The cross-section of the conveying track is semi-enclosed, which can block impurities and lubricating oil, effectively reducing the dripping of impurities and lubricating oil and reducing the impact on subsequent processes.
[0012] 2. The automatic conveying mechanism of the new energy vehicle headlight painting production line of the present invention involves a headlight suspended below a hook via a tooling basket. When an electromagnet is energized, it repels a permanent magnet, causing a first block to lift a second block, thus counteracting the pulling force of the headlight on the hook. The first block can slide freely relative to the sliding block. The magnetic force of the first electromagnet can be set to ensure that the repulsive force between the first electromagnet and the permanent magnet is exactly equal to the weight of the headlight inside the tooling basket, so that the end of the first block is suspended in the sliding groove of the sliding block. Subsequently, a drive motor drives a first gear to rotate, which, in conjunction with a first rack, allows the sliding block to move relative to the conveying track. This reduces friction and wear, thereby reducing the generation of metal particles and lowering lubrication requirements. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0016] like Figure 1As shown, the automatic conveying mechanism of the new energy vehicle headlight painting production line of the present invention includes: a hook 1, on which the new energy vehicle headlight is suspended by a tooling basket below the hook 1; the automatic conveying mechanism of the new energy vehicle headlight painting production line also includes: an anti-pollution unit 2, which includes a conveying track 21. The anti-pollution unit 2 reduces the friction and compression of the internal load-bearing components on the conveying track 21 due to gravity by using the mutual repulsion of like pole magnetic forces, thereby reducing the wear of the internal load-bearing components and the conveying track 21, thereby reducing the generation of metal shavings, and also reducing the lubrication requirements and reducing the accumulation and dripping of lubricating oil; the cross-section of the conveying track 21 is semi-enclosed, which can block impurities and lubricating oil, effectively reducing the dripping of impurities and lubricating oil; During the painting process of new energy vehicle headlights, a suspended conveyor chain is typically used. Traditional suspended conveyor chains require regular lubrication with large amounts of lubricating oil, which can easily accumulate and drip, contaminating the headlights and the pretreatment bath solution. Furthermore, the traditional suspended conveyor chain, due to compression, inevitably generates metal particles through friction, and over time, dust can accumulate. These metal particles or dust falling onto the headlights or into the pretreatment bath solution can also affect subsequent processes. Therefore, an anti-contamination unit 2 is installed. This unit includes a conveyor track 21. The anti-contamination unit 2 uses the repulsion of like-pole magnetic forces to reduce the friction and compression on the conveyor track 21 caused by gravity on the internal load-bearing components, thereby reducing wear on the internal load-bearing components and the conveyor track 21, and thus reducing the generation of metal shavings. It also lowers lubrication requirements and reduces the accumulation and dripping of lubricating oil. The conveyor track 21 has a semi-enclosed cross-section, specifically a "four"-shaped cross-section with a transparent center at the bottom. Figure 6 As shown, it can block impurities and lubricating oil, effectively reducing the dripping of impurities and lubricating oil and minimizing the impact on subsequent processes.
[0017] As one specific embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 10As shown in the figure, the anti-pollution unit 2 includes: a permanent magnet 22, the cross-section of the conveying track 21 is in the shape of the Chinese character "si" and the central position at the bottom is transparent; several permanent magnets 22 are fixedly laid on both sides of the bottom of the conveying track 21 near the central part; a slider 23, on both sides inside the conveying track 21, there are first grooves 24, and several sliders 23 are evenly slidably connected in each first groove 24. The top of each slider 23 coincides with the top of the first groove 24, and the bottom of each slider 23 is flush with the inner bottom of the conveying track 21; a first block 25, a first block 25 is slidably connected to each slider 23. The sliders 23 on both sides of the conveying track 21 correspond to each other in position and are grouped in pairs. The first blocks 25 on each pair of sliders 23 are commonly fixedly connected to a second block 26. The second block 26 is located at the central part of the conveying track 21 and a hook 1 is arranged at the bottom; the bottom of each first block 25 corresponds to the position of the permanent magnet 22 and a first electromagnet 27 is fixedly arranged. When the first electromagnet 27 is powered on, it repels the permanent magnet 22; a first gear 28, a driving motor is arranged at a position near the bottom inside each slider 23, the output shafts of the driving motors are commonly fixedly connected to first gears 28, and a first rack 29 is fixedly connected to a position near the bottom of the side wall of each first groove 24. The first gear 28 meshes with the corresponding first rack 29; As Figure 9 As shown in the figure, a first cavity 3 is opened inside the second block 26. A conductive plate 31 is fixedly connected to one side wall of the first cavity 3, a resistance plate 32 is fixedly connected to the other side wall of the first cavity 3. The bottom of the resistance plate 32 is connected to the control circuit of the first electromagnet 27. A power connection plate 33 is slidably connected inside the first cavity 3. The power connection plate 33 contacts the conductive plate 31 and the resistance plate 32. A hook 1 is fixedly connected to the bottom of the power connection plate 33. A first spring 34 is fixedly connected between the bottom of the power connection plate 33 and the bottom of the first cavity 3; the conductive plate 31 is connected to a power source; During operation, the headlight is suspended below hook 1 via a tooling basket for the pre-treatment stage of painting. At this time, electromagnet 27 is energized, repelling permanent magnet 22, causing block 25 to lift block 26, thus counteracting the pulling force of the headlight on hook 1. Block 25 can slide freely relative to sliding block 23. The magnetic force of electromagnet 27 can be set to ensure that the repulsive force between electromagnet 27 and permanent magnet 22 is exactly equal to the weight of the headlight inside the tooling basket, so that the end of block 25 is suspended in the sliding groove of sliding block 23. Subsequently, the drive motor drives gear 28 to rotate, cooperating with rack 29, allowing sliding block 23 to move relative to... The conveyor track 21 moves, thus reducing friction and wear, thereby reducing the generation of metal particles and lowering lubrication requirements. The power supply, conductive plate 31, junction plate 33, and resistor plate 32 together form the control circuit of electromagnet 27. The heavier the vehicle headlight in the tooling basket, the lower the hook 1 moves, that is, the lower the junction plate 33 moves. Similar to the principle of a sliding rheostat, the shorter the resistor plate 32 connected to the circuit, the smaller the resistance value, that is, the larger the current flowing into electromagnet 27, and the stronger the magnetic force of electromagnet 27. Therefore, the magnetic force of electromagnet 27 can be made to change with the weight below the hook 1, so as to adapt to the multi-weight mode and reduce friction.
[0018] As one specific embodiment of the present invention, such as Figure 6 , Figure 8 , Figure 9 As shown, a brush 4 is rotatably connected to the bottom of each gear 28, and the brush 4 fits into the bottom of the slot 24. like Figure 1 , Figure 6 , Figure 10 As shown, the bottom of the first trough 24 is provided with several dust collection holes 5, each dust collection hole 5 penetrates the bottom of the conveying track 21, and a dust collection cylinder 51 is threadedly connected to the bottom of the conveying track 21 and to the part corresponding to each dust collection hole 5. During operation, the bottom of the first groove 24 is lower than the bottom of the conveying track 21, and the wear of the first gear 28 and the first rack 29 also easily produces metal particles, which tend to accumulate at the bottom of the first groove 24. Therefore, when the sliding block 23 moves, it drives the first brush 4 to move at the bottom of the first groove 24, scraping the impurities into the dust collection hole 5, and then into the dust collection cylinder 51 to complete the collection of impurities and reduce the impact of impurities falling on the process. The dust collection cylinder 51 is a threaded connection that can be disassembled and can be disassembled periodically to process the impurities.
[0019] As one specific embodiment of the present invention, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, a fixed rod 6 is fixed between each pair of sliding blocks 23 in each slot 24. The fixed rod 6 is close to the bottom of the conveying track 21. A scraper plate 61 is fixed near the center of each fixed rod 6. The bottom of the scraper plate 61 is in contact with the bottom of the conveying track 21. like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 11 As shown, each scraper plate 61 has a second cavity 7 on one side near the center of the conveying track 21. A first bevel gear 71 is rotatably connected to the side wall of the second cavity 7; a second bevel gear 72 is rotatably connected to the top of the second cavity 7; and a third bevel gear 73 is rotatably connected to the bottom of the second cavity 7. The first bevel gear 71, second bevel gear 72, and third bevel gear 73 mesh with each other. A first shaft 74 is fixedly connected to the second bevel gear 72. The first shaft 74 is rotatably connected to the scraper plate 61 and its top extends through the top of the scraper plate 61. A pulley 75 is fixedly connected to the top of the first shaft 74. The third bevel gear... Gear 73 is fixedly connected to shaft 76. Shaft 76 passes through bevel gear 71, shaft 74, and pulley 75 and is rotatably connected to bevel gear 71, shaft 74, and pulley 75. A contact wheel 77 is fixedly connected to the top of shaft 76. The contact wheel 77 is located above pulley 75 and contacts the side wall of the conveyor track 21 near the center. A pulley 75 is rotatably connected to the top of the other side of scraper plate 61. A belt 78 is sleeved between the two pulleys 75 at the top of scraper plate 61. Several brushes 79 are fixedly connected to the bottom of belt 78. During operation, dust inevitably accumulates over time in the area from the first trough 24 to the center of the conveyor track 21. The shape of the conveyor track 21 effectively prevents impurities from falling. As the sliding block 23 moves forward, the scraper plate 61 scrapes away the dust in the area from the first trough 24 to the center of the conveyor track 21. The contact wheel 77 contacts the inner wall of the conveyor track 21, causing the contact wheel 77 to rotate. Because the first bevel gear 71, the second bevel gear 72, and the third bevel gear 73 mesh with each other, the pulley 75 rotates in the opposite direction, driving the first belt 78 to rotate, causing the second brush 79 to move. Because the pulley 75 rotates in the opposite direction, the second brush 79 moves. The movement direction of the first brush 79 is such that the impurities collected by the scraper 61 are swept into the first groove 24; then, as the sliding block 23 moves forward, the scraper 61 scrapes the bottom of the conveyor track 21, causing the impurities to accumulate in front of the scraper 61, thus completing the collection of impurities. Subsequently, the second brush 79 sweeps the impurities collected in front of the scraper 61 into the first groove 24. The impurities enter the first groove 24 and are brushed by the first brush 4, entering the dust collection cylinder 51 for easy cleaning and collection; the first rack 29 is installed in an embedded manner on the side wall of the first groove 24, so there is no need to worry about the impurities swept by the second brush 79 falling onto the first rack 29.
