[0034] S4. Curing treatment: The sprayed gear is transported to the curing treatment chamber under the conveyor for coating curing. The curing process temperature is controlled at 180°C-200°C for 30min-50min.

[0035] S5. Surface quality inspection: Carry out coating molding inspection on the processed gears, and the gears can be discharged if they pass the inspection.

[0036] In order to achieve the above-mentioned multiple processing steps to be efficient and continuous during the processing, the processing and conveying device of the coating processing process includes a conveying module and a coating processing module. The conveying module includes a horizontal material guide table 1 and an annular processing guide table 2. The coating processing module includes a pretreatment chamber 3 arranged outside the horizontal material guide table 1 and a grinding chamber 4, a spraying chamber 5 and a curing processing chamber 6 arranged around the annular processing guide table 2. Relying on the joint working mechanism design of the horizontal material guide table 1 and the annular processing guide table 2, the coherent implementation of multiple steps S1-S5 in the process can be achieved to ensure the processing and coating forming quality in a short time.

[0037] During the pretreatment process, Figure 2 and Figure 3As shown, the horizontal material guide platform 1 is provided with a conveying trough block 7, the conveying trough block 7 is provided with a gear slot 8, and the horizontal material guide platform 1 is provided with a conveying gas rod 9 for driving the conveying trough block 7 to slide. The processing personnel buckle the gear disc to be processed into the gear slot 8 part, and the conveying trough block 7 is fed under the drive of the conveying gas rod 9. The pretreatment chamber 3 includes a cleaning chamber 31 and a drying chamber 32, and the cleaning chamber 31 and the drying chamber 32 are covered on the horizontal material guide platform 1, that is, as the gear block is transported along the horizontal material guide platform 1 and passes through the cleaning chamber 31 and the drying chamber 32 respectively, the cleaning agent is used to clean it and remove the oil and impurities on the surface. Ensure that the surface is clean and oil-free, and keep the surface of the gear block dry.

[0038] After completing the pre-processing process, the gear disc needs to undergo a surface grinding process. The annular processing guide platform 2 is provided with a transfer slot block 10, which is used to receive and transfer the gear block of the horizontal material guide platform 1. The annular processing guide platform 2 is provided with an electric slide rail 11 that drives the transfer slot block 10 to slide. The transfer slot block 10 is rotatably connected to the electric slide rail 11. The initial position keeps the transfer slot block 10 aligned with the horizontal material guide platform 1. The transfer slot block 10 is provided with an auxiliary slot block 12 that cooperates with the gear slot 8. Under the operation of the conveying gas rod 9, the conveying slot block 7 is driven to slide to the transfer slot block 10. At this time, the pre-processed gear block is placed in the auxiliary slot block 12. The bottom of the slot of the auxiliary slot block 12 is provided with a gear block 13. The gear block 13 is movably connected to the transfer slot block 10. The operation of the gear block 13 can be used to achieve the connection with the middle transfer slot of the gear, thereby realizing the assembly limit of the gear block to be processed and the transfer slot block 10. The transfer slot block 10 is provided with an embedding slot 14 for the gear block 13 to engage with, and a driving cylinder 15 for driving the gear block 13 to rise and fall is provided in the embedding slot 14. The side wall of the auxiliary slot block 12 is provided with an induction coil 16 that cooperates with the driving cylinder 15. When the conveying slot block 7 conveys the gear block to the transfer slot block 10, the induction coil 16 senses the gear position and outputs a signal to control the driving cylinder 15 to lift, so that the gear block 13 is engaged with the rotating slot in the middle of the gear block to be processed. At the same time, the conveying slot block 7 is driven by the retraction action of the conveying gas rod 9 to achieve reset and circulation work.

[0039] The conveying trough block 7 continues to move along the annular processing guide table 2, and the electric slide rail 11 drives the gear block as a whole to pass through the grinding chamber 4, the spraying chamber 5 and the curing processing chamber 6 in sequence. The surface treatment, coating spraying and curing treatment segmented processes are respectively realized. Considering the full degree of treatment, a step block 17 is provided on the gear clamp block 13, and the gear block is suspended on the gear clamp block 13 to ensure the treatment effect of the bottom surface of the gear block during the grinding and spraying process.

[0040] After completing all the processing steps S1-S4, the transfer groove block 10 returns to the initial position of the annular processing guide table 2. A detection and discharge assembly is also provided above the horizontal guide table 1 for performing gear surface quality inspection and discharge process. The detection and discharge assembly includes a discharge guide table 18, a discharge slider 19 movably connected to the discharge guide table 18, and a detection cavity 20. The discharge guide table 18 is provided with an electric signal guide groove 21 for controlling the sliding movement of the discharge slider 19. The discharge slider 19 moves along the electric signal guide groove 21. A gear clamping block is provided on the discharge slider 19. The gear clamping block includes a driving bottom block 22 fixed to the discharge slider 19 and a tooth groove block 23 telescopically connected to the driving bottom block 22. The side of the tooth groove block 23 away from the driving bottom block 22 is also provided with an induction telescopic block 2 4. The side of the tooth groove block 23 is also provided with a sensing strip 25 that cooperates with the sensing telescopic block 24. When the processed gear block moves to the initial position along with the transfer groove block 10, the gear clamping block located above is clamped, and the tooth groove block 23 is vertically extended under the drive of the driving bottom block 22 until it is engaged with the middle rotation groove of the gear. During this process, the gear block 13 shrinks. When the sensing strip 25 on the tooth groove block 23 senses that the tooth groove block 23 is fully engaged, the sensing telescopic block 24 extends out to achieve the engagement limit with the gear block.

[0041] The driving bottom block 22 drives the tooth groove block 23 to lift vertically, and the discharging slider 19 slides and discharges the material at the same time. The detection chamber 20 is arranged below the discharging guide platform 18. A plurality of industrial visual cameras and a detection control block are arranged in the detection chamber 20. As the discharging slider 19 with the gear block clamped therein passes through the detection chamber 20 quickly, a plurality of industrial visual cameras in the detection chamber 20 collect data on the surface of the gear block at high speed. The detection control block realizes real-time data processing and three-dimensional construction, so as to timely analyze the key parameters such as the molding flatness and coating thickness of the gear surface. Once the relevant vertical abnormality is detected, timely feedback is given to the staff. Considering the reliable and efficient acquisition of the gear surface parameters, the driving bottom block 22 includes a rotating driving block 241 and a telescopic driving block 242, that is, to ensure that the gear is rotating while passing through the detection chamber 20, and the rotating driving block 241 works synchronously, so as to realize the circumferential rotation of the gear to facilitate the acquisition of the coating image parameters, and finally to ensure that the output coated gear is of qualified and reliable quality.

However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
