Description

Technical Field

[0001] This application relates to the field of coating equipment technology, and in particular to a coating treatment device specifically for optical glass lens processing. Background Technology

[0002] In the field of optical glass lens processing, coating is a core process for improving the optical performance and durability of lenses. With the rapid development of industries such as consumer electronics and optical instruments, the market has placed higher demands on the efficiency, quality stability, and equipment adaptability of lens coating. However, the coating equipment currently used in the industry still has some prominent technical pain points, making it difficult to meet the needs of large-scale, high-precision production.

[0003] On the one hand, most existing coating equipment adopts a semi-automatic operation mode, with processes such as feeding, coating, and drying relying on manual connection and transfer. This not only results in low production efficiency, but also makes it easy for dust and impurities to adhere to the lens surface during manual operation, damaging the cleanliness and uniformity of the coating layer and making it difficult to ensure the stability of coating quality in mass production. At the same time, manual transfer also increases the risk of lens impact damage, further increasing the production cost and quality control difficulty for enterprises.

[0004] On the other hand, the core mechanism design of traditional equipment has obvious defects: the coating execution mechanism is mostly a fixed structure, which cannot flexibly adjust the height and position of the nozzle, making it difficult to adapt to the coating needs of lenses with different curvatures and diameters; the lens clamping structure adopts a hard contact design, which is prone to causing bumps and damage to the lens edges, affecting optical accuracy; the hot air circulation system design in the drying and curing process is unreasonable, and the hot air distribution is uneven, resulting in differences in the curing effect of the coating layer and making it difficult to improve the product yield.

[0005] Therefore, developing a dedicated coating processing device that can achieve automated continuous operation, adapt to multiple lens specifications, and ensure the stability of coating quality has become a key issue that the industry urgently needs to address. Summary of the Invention

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. Through the seamless connection design of the feeding conveyor track, coating treatment chamber, drying and curing chamber and unloading conveyor track, coupled with the alternating cycle operation of the double clamp mounting frame, the entire process of optical glass lens coating is automated and continuous. This not only reduces dust contamination and bump damage caused by manual intervention, ensuring the stability of coating quality, but also shortens the process waiting time through the alternating operation of the double clamp, greatly improving production efficiency. At the same time, the compact layout also effectively saves the workshop floor space.

[0017] 2. By utilizing the adjustable structure of the lifting and adjusting frame and vertical slide rail of the coating execution component, combined with the flexible buffer pad design of the lens clamp, the problems of poor adaptability and easy lens damage of traditional equipment are solved. The lifting and adjusting frame can flexibly adjust the height of the coating nozzle to adapt to the coating needs of lenses with different curvatures and diameters. The flexible buffer pad avoids the impact damage to the lens edges caused by hard contact clamping. Combined with the linkage structure, it ensures that the lens is always in a horizontal state during the coating process, which greatly improves the uniformity and yield of the coating layer, allowing the equipment to better adapt to the production needs of lenses of various specifications.

[0018] 3. The coordinated design of the hot air circulation fan's outlet guide plate and hot air diffusion grille, along with the closed connection of the transition conveying channel, optimizes the drying and curing effect of the coating layer. The outlet guide plate guides the hot air to diffuse evenly into the cabin space, and the closed design of the transition conveying channel prevents the lens from being exposed to the outside world when it is transferred between cabins, reducing the risk of dust contamination. This allows the coating layer to cure quickly in a uniform and stable hot air environment, further improving the adhesion and durability of the coating layer and ensuring the quality stability of mass production.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-8 This invention provides a special coating treatment device for optical glass lens processing, including a feeding conveying mechanism 1, a coating operation main cabinet 102, a coating treatment chamber 103, a drying and curing chamber 105, and a discharging conveying track 104. The feeding conveying mechanism 1 includes a feeding conveying track 101, the output end of which is connected to the inlet end of the coating treatment chamber 103, the outlet end of the coating treatment chamber 103 is connected to the inlet end of the drying and curing chamber 105, and the outlet end of the drying and curing chamber 105 is connected to the input end of the discharging conveying track 104. The coating treatment chamber 103 is disposed on the top of the coating operation main cabinet 102. The interior is equipped with a coating execution component 2, a lens moving component 3, and a lens clamp 4. The lens moving component 3 includes a first drive cylinder 301, a transverse slide rail 302, and two clamp mounting brackets 307. The output end of the first drive cylinder 301 is connected to a sliding component on the transverse slide rail 302. The two clamp mounting brackets 307 are respectively mounted on the sliding component of the transverse slide rail 302. One clamp mounting bracket 307 is used to transfer the lens on the feeding conveyor rail 101 to the lens clamp 4, and the other clamp mounting bracket 307 is used to transfer the coated lens to the drying and curing chamber 105. A hot air circulating fan 5 is provided on the top of the drying and curing chamber 105.

[0030] The loading conveyor track 101 moves the optical glass lens to be processed along the conveying direction. After the lens reaches the output end of the loading conveyor track 101, the lens moving component 3 in the coating treatment chamber 103 starts to work. The first drive cylinder 301 drives the sliding component on the transverse slide rail 302 to move, which drives the two clamping mounting brackets 307 to move laterally in sync. One of the clamping mounting brackets 307 moves to the output end position of the loading conveyor track 101, clamps the lens, and moves laterally to the top of the lens clamp 4 to place the lens on the lens clamp 4. Then the coating execution component 2 starts to perform coating operation on the lens on the lens clamp 4. After the coating is completed, the other clamping mounting bracket 307 moves to the top of the lens clamp 4, clamps the coated lens, and moves laterally to the feed end of the drying and curing chamber 105 to send the lens into the drying and curing chamber 105. The hot air circulation fan 5 at the top of the drying and curing chamber 105 starts to generate hot air to dry and cure the lens. After the processing is completed, the lens is sent out of the device through the unloading conveyor track 104. Throughout the process, the coating operation main cabinet 102 provides installation support for the coating treatment chamber 103. The various mechanisms are connected in sequence through the feeding conveyor rail 101, the coating treatment chamber 103, the drying and curing chamber 105, and the unloading conveyor rail 104 to achieve automated continuous processing of the lenses.

[0031] Through automated continuous operations of loading, coating, drying, and unloading, the efficiency of optical glass lens coating processing is greatly improved, errors and contamination caused by manual intervention are reduced, and the stability of lens coating quality is guaranteed. The cyclic mode of alternating operation of the dual-clamp mounting frame 307 shortens the waiting time of the process and further improves production efficiency. The docking design of each compartment and the conveying mechanism makes the overall layout of the equipment compact and saves workshop floor space.

[0032] In a preferred embodiment, the coating execution assembly 2 includes a storage bin 201, a lifting adjustment frame 202, a vertical slide rail 203, a sliding mounting base 204, and a coating nozzle 205. The storage bin 201 is installed on the top of the coating processing chamber 103, the lifting adjustment frame 202 is fixed to the top of the inner wall of the coating processing chamber 103, the vertical slide rail 203 is installed vertically on the lifting adjustment frame 202, the sliding mounting base 204 is slidably installed on the vertical slide rail 203, and the coating nozzle 205 is installed at the bottom of the sliding mounting base 204 and is connected to the storage bin 201.

[0033] The storage bin 201 stores the coating solution required for coating. When a coating operation is required, the lifting adjustment frame 202 drives the vertical slide rail 203 to adjust its overall height to adapt to the coating requirements of lenses of different specifications. Then, the sliding mounting base 204 slides down along the vertical slide rail 203, driving the coating nozzle 205 at the bottom to approach the lens on the lens clamp 4. The coating solution in the storage bin 201 is transported to the coating nozzle 205 through the pipeline. The coating nozzle 205 sprays the coating solution evenly on the surface of the lens to complete the coating operation. After the coating is completed, the sliding mounting base 204 slides up along the vertical slide rail 203 to reset. The lifting adjustment frame 202 can also be adjusted again as needed to prepare for the next coating operation.

[0034] In a preferred embodiment, the lens moving assembly 3 further includes a clamp support 303, a positioning block 304, a clamp adjusting cylinder 305, a connecting block 306, and an arc-shaped positioning groove 308. The clamp support 303 is fixedly installed on the sliding component of the transverse slide rail 302, and two clamp mounting brackets 307 are respectively fixedly installed at both ends of the clamp support 303. The connecting block 306 is fixedly installed on one side of the clamp mounting bracket 307, the clamp adjusting cylinder 305 is installed on the connecting block 306, the positioning block 304 is fixedly installed at the output end of the clamp adjusting cylinder 305, and the arc-shaped positioning groove 308 is opened at the bottom of the clamp mounting bracket 307, and the positions of the arc-shaped positioning groove 308 and the positioning block 304 are vertically corresponding, for cooperating with the positioning block 304 to clamp and position the lens.

[0035] When the fixture mounting frame 307 moves to the position to be picked up, the fixture adjusting cylinder 305 is activated, pushing the positioning block 304 downward. The positioning block 304 cooperates with the arc-shaped positioning groove 308 at the bottom of the fixture mounting frame 307 to clamp the lens from the top and bottom, achieving stable positioning of the lens. After clamping, the first drive cylinder 301 drives the sliding component of the transverse slide rail 302 to move, causing the fixture support 303 and the fixture mounting frames 307 at both ends to move laterally synchronously, transferring the lens to the target position. After reaching the position, the fixture adjusting cylinder 305 drives the positioning block 304 to move upward to reset, releasing the lens and completing the transfer action. The connecting block 306 provides stable mounting support for the fixture adjusting cylinder 305, ensuring the reliability of the clamping action.

[0036] In a preferred embodiment, the lens clamp 4 includes a second drive cylinder 401, a telescopic rod 402, a mounting plate 403, an inclined support rod 404, a hinge seat 405, a drive rod 406, and a lens placement ring 407. The second drive cylinder 401 is installed at the bottom of the coating treatment chamber 103. The output end of the second drive cylinder 401 is connected to the telescopic rod 402. The top end of the telescopic rod 402 is connected to the mounting plate 403. The hinge seat 405 is fixed to the top of the outer wall of the second drive cylinder 401. One end of the inclined support rod 404 is hinged to the hinge seat 405. The other end of the drive rod 406 is fixedly connected to the lens placement ring 407. One end of the drive rod 406 is hinged to the mounting plate 403 via the inclined support rod 404, and the other end of the drive rod 406 is hinged to the inclined support rod 404.

[0037] When the lens to be coated is moved above the lens clamp 4, the second drive cylinder 401 is activated, driving the telescopic rod 402 to extend upward, causing the mounting plate 403 to rise. During the ascent of the mounting plate 403, the hinged drive rod 406 pushes the inclined support rod 404 to rotate around the hinge seat 405. The inclined support rod 404 causes the lens placement ring 407 to unfold upward to a horizontal state, at which point the lens placement ring 407 is in the ready-to-receive position. After the lens is placed on the lens placement ring 407, the second drive cylinder 401 drives the telescopic rod 402 to retract downward, causing the mounting plate 403 to descend. During the descent of the mounting plate 403, the drive rod 406 pulls the inclined support rod 404 to rotate in the opposite direction, keeping the lens placement ring 407 in a horizontal state and stably supporting the lens, thus cooperating with the coating execution component 2 to complete the coating operation. After the coating is completed, the second drive cylinder 401 drives the telescopic rod 402 to rise again, causing the lens placement ring 407 to rise to the pick-up position, waiting for another clamp mounting frame 307 to remove the lens. The flexible cushioning pad on the inner wall of the lens placement ring 407 further conforms to the edge of the lens, improving support stability.

[0038] The cooperation between the second drive cylinder 401 and the telescopic rod 402 enables automated control of the lifting and unfolding / resetting actions of the lens placement ring 407, eliminating the need for manual adjustment and improving work efficiency. The linkage structure of the inclined support rod 404, drive rod 406, and hinge seat 405 ensures smooth and controllable movement of the lens placement ring 407, guaranteeing the horizontal state of the lens during the coating process and improving coating uniformity. The flexible buffer pad prevents hard contact between the lens and the lens placement ring 407, preventing bumps and damage to the lens edges and protecting the optical precision of the lens.

[0039] In a preferred embodiment, the hot air circulating fan 5 includes a fan body, a fan mounting frame 501, an air outlet guide plate 502, and a hot air diffusion grille 503; the fan mounting frame 501 is installed on the top of the drying and curing chamber 105, the fan body is installed on the fan mounting frame 501, the air outlet guide plate 502 is installed below the air outlet end of the fan body, and the hot air diffusion grille 503 is installed on the inner top wall of the drying and curing chamber 105, and the hot air diffusion grille 503 is arranged corresponding to the air outlet guide plate 502.

[0040] When the coated lens enters the drying and curing chamber 105, the hot air circulating fan 5 starts and generates hot air. The hot air is guided to the hot air diffusion grille 503 through the air outlet guide plate 502. The hot air diffusion grille 503 evenly diffuses the hot air into the interior space of the drying and curing chamber 105, performing all-round drying and curing treatment on the lens. The hot air circulates in the chamber to ensure uniform temperature, so that the coating layer on the lens surface can be cured quickly and with stable performance. The fan mounting bracket 501 provides a stable installation support for the fan body to prevent vibration during equipment operation from affecting the drying effect.

[0041] In a preferred embodiment, the top of the feeding conveyor track 101 is provided with a plurality of placement slots for positioning lenses, and the plurality of placement slots are arranged at equal intervals along the conveying direction of the feeding conveyor track 101.

[0042] The optical glass lenses to be processed are placed in the placement slots at the top of the feeding conveyor track 101. The placement slots are arranged at equal intervals along the conveying direction. After the feeding conveyor track 101 is started, it drives the lenses to move smoothly along the conveying direction. Each placement slot corresponds to one lens, ensuring that the lenses will not shift or collide with each other during the transfer process, until the lenses reach the output end of the feeding conveyor track 101 and wait for the fixture mounting frame 307 to pick them up.

[0043] In a preferred embodiment, a transition conveying channel is provided between the coating treatment chamber 103 and the drying and curing chamber 105, and the two ends of the transition conveying channel are respectively connected to the discharge end of the coating treatment chamber 103 and the feed end of the drying and curing chamber 105.

[0044] After coating, the lens is transferred by the fixture mounting frame 307 to the discharge end of the coating treatment chamber 103 and then enters the transition conveying channel. The transition conveying channel smoothly conveys the lens to the feed end of the drying and curing chamber 105, so that the lens remains stable during the transfer between the coating treatment chamber 103 and the drying and curing chamber 105, avoiding exposure to the external environment and contamination by dust and impurities, while ensuring the smooth connection of the process.

[0045] In a preferred embodiment, the inner wall of the lens placement ring 407 is provided with a flexible buffer pad, which is made of rubber.

[0046] The flexible cushioning pad made of rubber has good elasticity and anti-slip properties, which can not only avoid damage caused by hard contact between the lens and the lens placement ring 407, but also improve the stability of the lens on the placement ring and prevent the lens from shifting during the coating process.

[0047] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a coating treatment apparatus for optical glass lens processing provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
