Description

Technical Field

[0001] This utility model belongs to the field of gear manufacturing technology, and in particular relates to a coating device for gear processing. Background Technology

[0002] Plastic gears are used for driving in some electrical appliances or toys. However, plastic gears are not wear-resistant, so they need to be coated with lubricant to reduce friction and extend their lifespan. In practice, however, operators rely on their experience to control the amount of lubricant, which can easily lead to problems such as too much or too little lubricant, as well as low efficiency, affecting production quality. Therefore, gear coating devices have emerged to replace manual labor.

[0003] Patent application CN201921494006.3 discloses a gear coating device, including a machine frame, a gear conveyor belt, a coating fixing bracket, and a coating device. The gear conveyor belt is mounted on the machine frame, the coating fixing bracket is fixedly mounted on the machine frame, and the coating device is fixedly mounted on the coating fixing bracket. The coating fixing bracket includes fixed columns on both sides of the machine frame and a bridge plate between the fixed columns. A slide rail is vertically mounted on the bridge plate, and the coating device is mounted on the slide rail via a slider. The coating device includes a housing and a coating head. A storage cavity is provided inside the housing, and the lower end of the storage cavity is connected to the outside through a through hole. A coating liquid input tank is provided at the bottom of the machine frame. The advantages of this invention are: simple operation, convenient control, significantly improved production efficiency; reduced defect rate of finished products, basically avoiding the generation of defective products; and standardized processing.

[0004] In existing technologies, the coating process can be completed during gear transmission by setting up structures such as the coating head and storage cavity, which effectively improves production efficiency. However, there are still some shortcomings in the overall use: the existing coating structure is relatively simple, and the coating is completed by a single roll. It lacks both corresponding detection and control structures and structures that can improve the coating quality, resulting in the overall coating quality and effect not being guaranteed. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a coating device for gear processing. By setting up multiple scrapers, flow channels, vibrators, and vision probes, this utility model enables the gear to not only receive multiple scraping coatings during coating treatment, but also to undergo vibration diffusion treatment. This effectively improves the coating quality while also enabling monitoring, thus effectively ensuring the coating quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating device for gear processing, comprising a transmission frame and a transmission belt. The transmission belt is driven within the transmission frame, and a connecting plate is slidably mounted above the transmission belt. Multiple air jet seats are mounted on one side of the upper surface of the connecting plate, and multiple connecting blocks are mounted on the bottom surface of the connecting plate on one side of each air jet seat. Scrapers are connected to the bottom surface of each connecting block, and each scraper has multiple flow grooves on its end face, each flow groove gradually increasing in size towards the air jet seats. A spray chamber is disposed within the connecting plate between the multiple scrapers, and multiple spray heads are mounted on the bottom surface of the spray chamber. The arrangement of the flow grooves and scrapers allows for multiple scraping coating processes on the gear end face.

[0007] Preferably, each of the jet seats has a jet nozzle on its bottom end face. The jet nozzle ensures effective cleaning of the gears.

[0008] Preferably, a bracket is fixedly mounted on one side of the transmission frame, and multiple push cylinders are mounted on the end face of the bracket. The output end of each push cylinder is connected to the end face of the connecting plate. The push cylinders enable the connecting plate to move stably up and down.

[0009] Preferably, multiple vibrators are provided on the end face of the connecting plate, and a support rod is connected to the bottom output end of each vibrator. A ball head is connected to the bottom end face of the support rod, and a rotating ball is rotatably disposed inside the ball head. The outer circumference of the rotating ball contacts the surface of the gear. The vibrators allow the coating on the end face of the gear to be vibrated and dispersed.

[0010] Preferably, a vision probe is provided on one side of the vibrator on the end face of the connecting plate. The presence of the vision probe ensures the coating effect.

[0011] Preferably, each scraper has multiple rough textures on its bottom end face. The rough textures ensure uniform application.

[0012] Preferably, the transmission frame has two rotating shafts, and the two rotating shafts are externally supported by a transmission belt.

[0013] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0014] This invention, through the arrangement of multiple scrapers, flow channels, vibrators, and vision probes, allows the gear exterior to undergo multiple scraping and coating processes during coating treatment, as well as vibration and diffusion treatment. This enables the coating material to flow to all parts of the exterior, effectively improving the coating quality while also allowing for monitoring of the gear and ensuring coating quality.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1:

[0025] refer to Figure 1-8 A gear processing coating device includes a transmission frame 31 and a transmission belt 33. The transmission belt 33 is driven inside the transmission frame 31. A connecting plate 35 is slidably arranged above the transmission belt 33. A plurality of jet seats 36 are arranged on one side of the upper end face of the connecting plate 35. A plurality of connecting blocks 38 are arranged on one side of the jet seats 36 on the bottom end face of the connecting plate 35. A scraper 39 is connected to the bottom end face of the connecting block 38. A plurality of flow grooves 47 are arranged on the end face of each scraper 39. Each flow groove 47 gradually increases in size towards the jet seat 36. A spray chamber 45 is arranged between the plurality of scrapers 39 in the connecting plate 35. A plurality of spray heads 46 are arranged on the bottom end face of the spray chamber 45.

[0026] Specifically, when the exterior of the gears needs to be coated, the operator places multiple gears outside the conveyor belt 33 and then starts the device. The conveyor belt 33 can drive multiple gears to move downwards towards the connecting plate 35. At this time, the connecting plate 35 will move downwards, so that the end face of the gears during the movement can contact multiple scrapers 39. When the gears are about to move to one side of the connecting plate 35, multiple jet seats 36 on the end face of the connecting plate 35 can spray high-pressure gas towards the end face of the gears, thereby cleaning the dirt on the exterior of the gears and ensuring the coating effect.

[0027] At this time, the spray chamber 45 located in the connecting plate 35 sprays the coating material onto the gear end face through multiple spray heads 46 on the bottom end face, thereby coating the gear. In this solution, the coating material is existing technology, including lubricating oil, rust inhibitor, etc., which will not be elaborated on in this solution. After the coating material is attached to the gear end face, as the gear is moved, the gear will carry the coating material to the bottom of multiple connecting blocks 38 and scraper blocks 39. The scraper blocks 39 are made of elastic material and can scrape the coating material on the gear end face, so that the coating material can be evenly coated on all parts of the gear end face. During this process, the excess coating material scraped off will flow to the other side through multiple flow channels 47, so that it can be scraped off again. The flow channels 47 have a larger opening towards the jet seat 36 and a smaller opening away from the jet seat 36, forming a funnel-shaped channel with an overall T-shaped cross-section, so that the excess coating material scraped off can flow to one side quickly. The scraping of multiple scraper blocks 39 can effectively improve the coating quality.

[0028] The gears, which have been scraped and coated multiple times, will eventually be moved to the other side by conveyor belt 33, where staff can pick them up.

[0029] refer to Figure 4 The transmission frame 31 has two rotating shafts 49 inside, and the two rotating shafts 49 are externally supported by the transmission belt 33.

[0030] Specifically, two rotating shafts 49 are respectively rotatably arranged on both sides inside the transmission frame 31. One of the rotating shafts 49 is externally connected to a drive motor, which is used to drive the rotating shaft 49 and the external transmission belt 33 for transmission processing, so that the gear material can be smoothly driven.

[0031] refer to Figure 4 A bracket 32 ​​is fixedly installed on one side of the transmission frame 31. Multiple push cylinders 34 are installed on the end face of the bracket 32. The output end of the push cylinder 34 is connected to the end face of the connecting plate 35.

[0032] Specifically, the push cylinder 34 is existing technology and will not be elaborated on in this solution. The output end of the push cylinder 34 can drive the connecting plate 35 to move up and down, so that the multiple scrapers 39 below the connecting plate 35 can fit against the end face of the gear, thereby ensuring the coating quality.

[0033] refer to Figure 8 Each jet mount 36 has a jet nozzle 37 on its bottom end face.

[0034] Specifically, the jet nozzle 37 is tilted, tilted towards the side away from the connecting block 38, which can effectively spray high-pressure gas onto the gear end face while removing dust and dirt.

[0035] refer to Figure 7 Each scraper block 39 has multiple rough textures 48 on its bottom end face.

[0036] Specifically, the textured surface 48 improves the surface roughness of the bottom end face of the scraper 39, ensuring the quality of pushing and blocking the coating material, so that excess coating material will not be coated on the gear end face, thereby improving the coating quality.

[0037] refer to Figure 5 Multiple vibrators 40 are provided on the end face of the connecting plate 35. A support rod 44 is connected to the bottom output end of the vibrator 40. A ball head seat 41 is connected to the bottom end face of the support rod 44. A rotating ball 42 is rotatably arranged inside the ball head seat 41. The outer circular surface of the rotating ball 42 is in contact with the surface of the gear.

[0038] Specifically, the vibrator 40 is existing technology and will not be elaborated on in this solution. When the gear moves under the multiple scrapers 39, the end face of the gear will also contact the outer surface of the multiple rotating beads 42. The rotating beads 42 are rotatably connected inside the ball head seat 41. When the gear contacts the rotating beads 42, the rotating beads 42 will rotate, so that the ball head seat 41 and the support rod 44 between the ball head seat 41 and the output end of the vibrator 40 can maintain a certain stability. At this time, the output end of the support rod 44 can vibrate the support rod 44 and the ball head seat 41, thereby vibrating the gear under the rotating beads 42, which can shake off the excess coating adhering to the outside of the gear, thus avoiding the situation where the coating accumulates in the corner.

[0039] Example 2:

[0040] Based on or differing from Embodiment 1, refer to Figure 6 A vision probe 43 is provided on one side of the vibrator 40 on the end face of the connecting plate 35.

[0041] Specifically, the vision probe 43 can monitor the coating situation on the gear end face. When the vision probe 43 finds that there are coating gaps or too much coating on the gear surface, it can control the conveyor belt 33 to rotate back, thereby adjusting the gear back to below the connecting plate 35, so as to perform secondary coating, ensuring the coating quality and effect.
