Abstract
Description
Technical Field
[0001] This application relates to the field of connector manufacturing technology, and in particular to an oiling and baking apparatus for connector manufacturing. Background Technology
[0002] In the field of electronic connector manufacturing, the oiling process is a crucial step in ensuring product performance and reliability. As electronic devices develop towards miniaturization, high precision, and high reliability, the application scenarios for connectors are constantly expanding, extending from traditional consumer electronics to high-end fields such as new energy vehicles, 5G communications, and aerospace. This places more stringent demands on the connectors' mating resistance, corrosion resistance, and stability.
[0003] Traditional connector lubrication processes primarily focus on achieving three core functions: lubrication, corrosion prevention, and wear resistance. Related data shows that friction between metal terminals during connector mating and unmapping can lead to severe wear on the plating. For example, without lubrication, the wear rate of gold plating can reach 70% after 10,000 mating cycles, while with effective lubrication, the wear rate can still be controlled below 15% after 50,000 mating cycles. This demonstrates the significant impact of lubrication processes on connector lifespan.
[0004] However, existing oiling processes and equipment have several significant shortcomings, making it difficult to meet the demands of high-end manufacturing: First, the uniformity of oiling is insufficient. Due to the easy incorporation of air into the oil, or insufficient relative positioning accuracy between the oiling device and the connector, problems such as incomplete or missed coatings easily occur on the connector surface, directly affecting lubrication and protection. Furthermore, these defects are difficult to visually identify under natural light. Second, detection methods are inefficient and costly. Traditional inspections rely heavily on manual visual inspection or simple optical checks, lacking targeted defect magnification methods, resulting in a high rate of missed detections. Simultaneously, manual inspection is inefficient and cannot keep pace with automated production lines, significantly increasing quality control costs. Third, recoating positioning accuracy is lacking. When oiling defects are detected, existing equipment cannot achieve precise reverse transport of the material strip, making it difficult to accurately return the defect location to the oiling station for secondary coating. This often leads to the direct scrapping of defective products or continued positional deviations after recoating, further exacerbating production costs and material waste.
[0005] These problems collectively restrict the yield, efficiency, and reliability of connector production, and there is an urgent need for an integrated device that combines precise oiling, efficient testing, accurate recoating, and residue treatment functions to break through the existing technological bottlenecks. Summary of the Invention
[0006] To address the aforementioned problems, this application provides an oiling and baking apparatus for connector manufacturing.
[0007] An oiling and baking device for connector manufacturing includes a conveyor table, an oiling device, a detection mechanism, a drive device, and a baking device arranged sequentially along the conveyor table. The drive device includes a motor-driven actuating gear that meshes with a drive hole in the connector strip to achieve precise transport of the strip. The actuating gear includes a rotating shaft. The drive device also includes a retraction mechanism that acts on the rotating shaft and causes the rotation direction of the rotating shaft to be opposite to the transport direction of the connector. The oiling device is used to coat the connector with an oil containing fluorescent whitening agent. The detection mechanism is used to detect the oiling status of the connector after oiling. The baking device is equipped with an ultraviolet lamp that can work with high temperature to decompose the fluorescent whitening agent in the oil. Based on the detection result of the detection mechanism, the retraction mechanism can be controlled to reverse the transport of the strip to the oiling position for recoating.
[0008] By adopting the above technical solution, precise transportation of connector tapes, efficient detection of oiling status, and precise reverse transportation and recoating when oiling is unqualified are achieved. At the same time, the fluorescent whitening agent in the oil is removed by baking. The solution integrates oiling, detection, recoating and residue treatment functions, effectively improving the yield and efficiency of connector production.
[0009] Preferably, the oiling device includes a pneumatic oil gun containing oil, wherein the oil contains stilbene-type fluorescent whitening agent at a concentration of 0.01%-0.1%.
[0010] By adopting the above technical solution, stilbene-type fluorescent whitening agent can emit blue-white visible light under ultraviolet light irradiation, which makes it easy for testing agencies to identify the oiled area. Moreover, this concentration range can ensure the testing effect without affecting the core performance of the oil, such as lubrication and corrosion prevention.
[0011] Preferably, the oiling device further includes an adjusting component, which includes a slide block with a locking block slidably disposed on the slide block along its length direction. The pneumatic oil gun is fixed on the locking block, and the slide block is also provided with an adjusting cylinder for driving the locking block to move along the slide block.
[0012] By adopting the above technical solution, the adjusting cylinder can drive the locking block to move the pneumatic oil gun along the slide, thereby adjusting the relative position of the pneumatic oil gun and the connector, thus adapting to connectors of different specifications and ensuring the accuracy of the oiling position.
[0013] Preferably, a guide plate is provided on the conveyor table, the guide plate is provided on both sides of the actuating gear, and a guide groove is formed between the guide plate and the conveyor table for the feed strip to pass through. The height of the guide groove is adapted to the thickness of the connector strip, and the guide plate can tightly press the connector against the conveyor table.
[0014] By adopting the above technical solutions, the guide groove can limit the lateral deviation of the material belt, and the guide pressure plate can ensure that the material belt is in close contact with the conveyor table, thereby improving the stability of the material belt during transportation and providing a guarantee for the accurate execution of subsequent processes such as oiling and testing.
[0015] Preferably, the detection mechanism includes an ultraviolet lamp and a vision camera. The ultraviolet lamp is used to irradiate the oiled area of the connector, causing the stilbene fluorescent whitening agent in the oil to emit blue-white visible light. The connector can pass through the shooting range of the vision camera, which is used to capture the blue-white light band of the oiled area to detect whether the oiling is uniform. The irradiation range of the ultraviolet lamp coincides with the working range of the vision camera.
[0016] By adopting the above technical solution, the ultraviolet lamp excites the fluorescent whitening agent to emit light, and the visual camera can clearly capture the light band of the oiled area. The continuity of the light band can be used to determine whether the oiling is uniform. Moreover, the irradiation range and the shooting range overlap, which improves the accuracy and efficiency of the detection.
[0017] Preferably, the testing mechanism further includes a warning light, which is used to emit a red light to warn when the testing mechanism detects uneven oiling of the connector.
[0018] By adopting the above technical solution, when uneven oiling is detected, the warning light can promptly issue a red warning, making it easier for operators to quickly detect abnormalities and understand the operating conditions of the equipment.
[0019] Preferably, the back-stepping mechanism includes a drive groove formed on the rotary shaft, the drive groove being wedge-shaped, and the number of wedge-shaped grooves corresponding one-to-one with the number of teeth of the rotary gear.
[0020] By adopting the above technical solution, the wedge-shaped drive groove provides a precise force-bearing point for the reverse rotation of the turntable shaft, and the number corresponds to the number of teeth, laying the foundation for precise distance control of the reverse transport of the material belt.
[0021] Preferably, the retraction mechanism further includes a housing, the housing having a groove inside which an elastic pressure plate is disposed, the elastic pressure plate being made of an elastic material; the housing also has multiple pressing plates for pressing the elastic pressure plate, the multiple pressing plates being coaxially arranged and all located at the top of the elastic pressure plate to restrict the position of the elastic pressure plate; a lifting roller is disposed at one end of the housing near the rotary shaft, the lifting roller abutting against the bottom of the elastic pressure plate and causing the elastic pressure plate to bend upward, so that the bent part of the elastic pressure plate is tangent to the rotary shaft, and the point of tangency between the elastic pressure plate and the rotary shaft is located at the deep groove position of the drive groove.
[0022] By adopting the above technical solution, the elastic pressure plate makes precise contact with the deep groove of the drive groove under the action of the lifting roller, and the pressing plate restricts its position, ensuring that the elastic pressure plate can stably drive the turntable shaft to rotate in the opposite direction, thereby improving the stability of the backstepping mechanism.
[0023] Preferably, the driving device further includes a swing mechanism for driving the elastic pressure plate to swing. The swing mechanism includes a wheel driven by a motor, a guide rail fixedly mounted on the wheel, and a U-shaped track groove on the guide rail. A roller is mounted on the wheel, the roller is installed on the outer edge of the wheel and is inserted into the track groove. The roller can move in the track groove as the wheel rotates to drive the guide rail to swing. For every one rotation of the wheel, the guide rail can swing back and forth once.
[0024] By adopting the above technical solution, when the wheel rotates, the roller moves along the zigzag track groove, which can drive the guide rail to swing back and forth stably, providing a continuous and stable driving force for the reciprocating movement of the elastic pressure plate.
[0025] Preferably, a first rocker arm is hinged to the guide rail, and a second rocker arm is hinged to the end of the first rocker arm away from the guide rail. The length of the second rocker arm is less than that of the first rocker arm. A connecting member is connected to the elastic pressure plate, and the second rocker arm is hinged to the connecting member to drive the elastic pressure plate to reciprocate. When the elastic pressure plate reciprocates once, it can push the rotary shaft to rotate through the deep groove position of the push drive groove, so that the rotary gear rotates a distance of one tooth.
[0026] By adopting the above technical solution, the hinged connection between the first and second swing arms can convert the swing of the guide rail into the reciprocating movement of the elastic pressure plate. Each reciprocating movement of the elastic pressure plate can drive the actuating gear to rotate by one tooth pitch, thus realizing precise distance control of the reverse transport of the material belt.
[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. It integrates functions such as precise oiling, efficient detection, accurate recoating and residue treatment, which solves the problems of poor oiling uniformity, low detection efficiency and inaccurate recoating positioning of traditional equipment, and effectively improves the yield of connector production; 2. By combining fluorescent whitening agent with ultraviolet detection, the accuracy and efficiency of coating uniformity detection are greatly improved, and the retraction mechanism realizes precise reverse transportation of the material belt, reducing the scrap of defective products and lowering production costs; 3. The adjustable spacing component of the oiling device can be adapted to connectors of different specifications, which improves the versatility of the equipment and meets diverse production needs.

Detailed Implementation
[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] In the description of the invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.
[0032] This application discloses an oiling and baking equipment for connector manufacturing, referring to... Figure 1 and Figure 2 The system includes a conveyor 20, along which are sequentially arranged an oiling device, a testing mechanism, a driving device, and a baking device 2. The connector strip 401 passes through these devices sequentially under the action of the conveyor 20, completing the processes of oiling, testing, precise transport, and baking. Reference Figure 1 and Figure 2The oiling device is used to coat connectors with an oil containing fluorescent whitening agent. It includes a pneumatic oil gun 11 and an adjustment assembly. The pneumatic oil gun 11 contains oil with a concentration of 0.01%-0.1% stilbene-type fluorescent whitening agent. The adjustment assembly includes a slide 13 with a locking block 14 slidably mounted on it along its length. The pneumatic oil gun 11 is fixed to the locking block 14. An adjusting cylinder 12 is also provided on the slide 13 to drive the locking block 14 to move along the slide 13. When oiling is required for connectors of different specifications, the adjusting cylinder 12 is activated, driving the locking block 14 to slide along the slide 13, thereby moving the pneumatic oil gun 11 and adjusting its position. This adjusts the distance between the oil outlet of the pneumatic oil gun 11 and the connector, ensuring accurate oiling position and thickness. The pneumatic oil gun 11 uses air pressure to push a piston, thus dispensing oil. Reference Figure 1 and Figure 2 A guide plate 201 is provided on the conveyor table 20, and the guide plate 201 is located on both sides of the actuating gear 31. A guide groove 202 is formed between the guide plate 201 and the conveyor table 20 for the feed strip to pass through. The height of the guide groove 202 is adapted to the thickness of the connector strip 401, and the guide plate 201 can keep the connector tightly against the conveyor table 20. During the transportation of the connector strip 401, the guide groove 202 guides the strip and prevents it from deviating, while the guide plate 201 ensures that the strip is in close contact with the conveyor table 20, ensuring the stability of transportation. Reference Figure 2 and Figure 4 The driving device includes a motor-driven actuating gear 31, which meshes with the drive hole 301 of the connector tape 401 to achieve precise transport of the tape. The actuating gear 31 includes a rotating shaft 32. The driving device also includes a retraction mechanism, which acts on the rotating shaft 32 and makes the rotation direction of the rotating shaft 32 opposite to the transport direction of the connector. The retraction mechanism includes a drive groove 41 formed on the rotating shaft 32. The drive groove 41 is wedge-shaped, and the number of wedge grooves corresponds one-to-one with the number of teeth of the actuating gear 31. The retraction mechanism also includes a housing 57, which has a sliding groove. An elastic pressure plate 42 is provided in the sliding groove. The elastic pressure plate 42 is made of elastic material and has a certain rebound effect. The housing 57 also has multiple pressing plates 43 for pressing the elastic pressure plate 42. The multiple pressing plates 43 are coaxially arranged and all located on top of the elastic pressure plate 42 to limit the position of the elastic pressure plate 42. A lifting roller 44 is provided at one end of the housing 57 near the rotary shaft 32. The lifting roller 44 abuts against the bottom of the elastic pressure plate 42 and can make the elastic pressure plate 42 bend upward, so that the bent part of the elastic pressure plate 42 is tangent to the rotary shaft 32, and the tangent point between the elastic pressure plate 42 and the rotary shaft 32 is located in the deep groove position of the drive groove 41.
[0033] Reference Figure 5 , Figure 6 and Figure 7 The driving device also includes a swing mechanism for driving the elastic pressure plate 42 to swing. The swing mechanism includes a wheel 51 driven by a motor. A guide rail 53 is fixedly mounted on the wheel 51, and a U-shaped track groove 54 is formed on the guide rail 53. A roller 52 is mounted on the wheel 51, and the roller 52 is installed on the outer edge of the wheel 51 and inserted into the track groove 54. The roller 52 can move within the track groove 54 as the wheel 51 rotates to drive the guide rail 53 to swing. For every one rotation of the wheel 51, the guide rail 53 can swing back and forth once. A first swing rod 55 is hinged to the guide rail 53, and a second swing rod 56 is hinged to the end of the first swing rod 55 away from the guide rail 53. The length of the second swing rod 56 is less than that of the first swing rod 55. A connecting member is connected to the elastic pressure plate 42, and the second swing rod 56 is hinged to the connecting member to drive the elastic pressure plate 42 to move back and forth. When the elastic pressure plate 42 moves back and forth once, it can push the dial shaft 32 to rotate through the deep groove position of the push drive groove 41, so that the dial gear 31 rotates a distance of one tooth.
[0034] Reference Figure 5 , Figure 6 and Figure 7 When the drive unit normally drives the connector tape 401 forward, the motor drives the actuating gear 31 to rotate. The actuating gear 31 meshes with the drive hole 301 of the tape, driving the tape forward. When it is necessary to reverse the tape transport, the retraction mechanism is activated. The motor of the swing mechanism drives the wheel 51 to rotate, and the roller 52 moves in the Z-shaped track groove 54 as the wheel 51 rotates, thereby driving the guide rail 53 to swing. The swing of the guide rail 53 drives the first swing rod 55 to swing, and the first swing rod 55 drives the second swing rod 56 to swing. The second swing rod 56 drives the elastic pressure plate 42 to reciprocate in the groove through the hinge with the connector. Under the action of the lifting roller 44, the elastic pressure plate 42 bends upward, and its bent part is tangent to the deep groove of the drive groove 41 with the rotating shaft 32. Because the drive groove 41 is a wedge-shaped groove, the elastic pressure plate 42 pushes the deep groove position of the drive groove 41 during reciprocating movement, driving the rotary shaft 32 to rotate in the opposite direction, thereby causing the actuating gear 31 to rotate in the opposite direction, realizing the reverse transport of the material belt. Furthermore, since the elastic pressure plate 42 reciprocates once for every one rotation of the wheel 51, the actuating gear 31 rotates one tooth's distance. Since the number of drive grooves 41 corresponds one-to-one with the number of teeth, the reverse transport distance of the material belt can be precisely controlled. Reference Figure 3The testing mechanism is used to inspect the oiling status of connectors after oiling. It includes an ultraviolet lamp 16 and a vision camera 15. The ultraviolet lamp 16 illuminates the oiled area of the connector, causing the stilbene-type fluorescent whitening agent in the oil to emit blue-white visible light. The connector must pass through the field of view of the vision camera 15, which captures the blue-white light band in the oiled area to detect whether the oiling is uniform. The illumination range of the ultraviolet lamp 16 coincides with the working range of the vision camera 15. The testing mechanism also includes a warning light 17, which emits a red light to warn of uneven oiling detected by the testing mechanism. Reference Figure 3 During the inspection, the ultraviolet lamp 16 illuminates the oiled area of the connector. The stilbene-type fluorescent whitening agent in the oil emits blue-white visible light under ultraviolet light. Since the illumination range of the ultraviolet lamp 16 overlaps with the working range of the vision camera 15, the vision camera 15 can clearly capture the blue-white light band of the oiled area. If the oiling is normal, the light band is a continuous blue-white light band; if the oiling is uneven, the light band will appear segmented. When the vision camera 15 detects segmented light bands, i.e., uneven oiling, the warning light 17 emits a red light as a warning. Reference Figure 1 The baking device 2 is used to dry the oil. It is equipped with an ultraviolet lamp and can work in conjunction with high temperature to decompose the fluorescent whitening agent in the oil. When a properly lubricated connector enters the baking device 2, the high temperature and ultraviolet lamp work together to completely decompose the stilbene-type fluorescent whitening agent in the oil.
[0035] The implementation principle of this application is as follows: When the connector tape 401 is transported on the conveyor 20, the guide grooves 202 on both sides of the conveyor 20 limit the lateral deviation of the tape, while the guide pressure plate 201 keeps the tape tightly against the conveyor 20, ensuring transportation stability. For connectors of different specifications, the adjusting cylinder 12 of the pitch adjustment component drives the locking block 14 to slide along the slide block 13, thereby moving the pneumatic oil gun 11 fixed on the locking block 14 to achieve precise calibration of the oiling position. The pneumatic oil gun 11 sprays oil containing 0.01%-0.1% stilbene-type fluorescent whitening agent onto the connector to complete the initial coating. After oiling, the tape enters the inspection area, and the ultraviolet lamp 16 irradiates the oiled area, causing the stilbene-type fluorescent whitening agent in the oil to be excited and emit blue-white visible light.
[0036] The vision camera 15 captures images of the oiling area, with the UV lamp's illumination range coinciding with the camera's working range to ensure clear imaging. The uniformity of the oiling is determined by analyzing the continuity of the blue-white light band; a continuous band indicates successful oiling, while segmented bands indicate uneven application. If uneven application is detected, the warning light 17 emits a red light, indicating an abnormality. When oiling is successful, the warning light remains off, with only the UV lamp emitting a purple light; uneven application results in a red warning light, visually indicating the equipment's operational status through the color of the light.
[0037] Based on the testing results from the testing agency, the retraction mechanism can be controlled to reverse the transport of the material strip to the oiling position for recoating. Since the distance from the vision camera 15 to the oil outlet of the pneumatic oil gun 11 is fixed, this distance corresponds to the number of rotations of the actuating gear 31, and each rotation corresponds to a certain number of drive grooves 41. When uneven oiling is detected, the equipment, according to the preset correspondence between distance, number of rotations, and number of drive grooves 41, controls the motor driving the retraction mechanism to rotate a corresponding number of times, causing the elastic pressure plate 42 to push the rotary shaft 32 to rotate the corresponding number of drive grooves 41, thereby precisely reversing the transport of the material strip to the oiling position for recoating.
[0038] The motor of the drive unit drives the rotating gear 31 to rotate. The gear meshes with the drive hole 301 of the material belt, and the gear teeth push the material belt to move precisely along the transport direction (forward) to achieve continuous transmission between processes. When uneven oiling is detected and recoating is required, the retraction mechanism is activated, and the motor of the swing mechanism drives the wheel 51 to rotate. The roller 52 on the outer edge of the wheel 51 slides in the Z-shaped track groove 54 of the guide rail 53, forcing the guide rail 53 to swing back and forth. For every one rotation of the wheel 51, the guide rail 53 swings once. The swing of the guide rail 53 drives the second swing rod 56 through the hinged first swing rod 55. The second swing rod 56 then drives the elastic pressure plate 42 to move back and forth in the sliding groove of the outer shell 57 through the connecting piece. The elastic pressure plate 42 bends upward under the push of the lifting roller 44, and the bent part is tangent to the deepest part of the wedge-shaped drive groove 41 of the rotating shaft 32. When the elastic pressure plate 42 reciprocates, its curved portion pushes against the deep groove of the drive groove 41, forcing the rotary shaft 32 to rotate in the opposite direction, which in turn drives the actuating gear 31 to rotate in the opposite direction. Since the number of drive grooves 41 corresponds one-to-one with the number of teeth on the gear, each time the elastic pressure plate 42 reciprocates, the actuating gear 31 rotates one tooth pitch in the opposite direction, and the material belt moves in the opposite direction a corresponding distance, eventually returning precisely to the oiling position. This method allows the equipment to accurately control the number of rotations of the motor drive wheel 51. One rotation of the drive wheel 51 corresponds to the rotary shaft 32 driving the actuating gear 31 to rotate one tooth pitch in the opposite direction, achieving the effect of precisely controlling the reverse rotation distance.
[0039] After the qualified oiled connectors enter the baking device 2, the high temperature and ultraviolet lamps inside the device work together to completely decompose the stilbene fluorescent whitening agent in the oil, completing the final treatment.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
