Description

Technical Field

[0001] This invention relates to the field of lens processing equipment technology, specifically to a surface hardening treatment device and method for swimming goggle lenses. Background Technology

[0002] Swimming goggles are currently a type of equipment used in swimming. They are worn close to the eyes and allow for clear vision underwater while preventing pool water from entering the eyes. As a result, they have become an essential item for many swimming enthusiasts. During the production process, swimming goggles require a hardening treatment on the lens surface. There are many methods for this treatment, including the immersion coating method, which involves soaking the lens in a solution containing a hardening agent, allowing the hardening agent to form a thin film on the lens surface.

[0003] According to Chinese Patent Publication No. CN218130434U, this patent provides a cleaning fluid circulation filtration system for an automatic lens surface hardening treatment device, including a frame, a placement tray, a receiving tray, and a circulation mechanism. The placement tray is fixed to the frame and is used to hold anti-fogging fluid. The circulation mechanism includes a storage tank, an inlet pipe, an outlet pipe, and a filter pump. The storage tank stores the anti-fogging fluid, one end of the inlet pipe is connected to the storage tank, and the other end of the inlet pipe is connected to the receiving tray. One end of the water outlet pipe is connected to the storage tank, and the other end of the water outlet pipe is connected to the receiving tray. The filter pump is connected to the water outlet pipe. Under the action of the filter pump, the water inlet pipe delivers the anti-fogging liquid in the storage tank to the receiving tray, and at the same time, the water outlet pipe delivers the anti-fogging liquid in the receiving tray to the storage tank. This not only realizes the reuse of the anti-fogging liquid and improves its utilization rate, but also allows the filter pump to remove fixed particles inside the anti-fogging liquid, thus filtering the anti-fogging liquid and increasing its overall cleanliness.

[0004] In traditional processes, lenses must be cleaned before hardening, followed by removal of residual water stains, batch loading, and finally immersion in a hardening tank. This multi-step process is time-consuming and cumbersome, reducing the efficiency of batch processing. Furthermore, loading and unloading batches of lenses places high demands on the adaptability of the fixtures, increasing the burden on manual operation. Therefore, this paper proposes a surface hardening treatment device and method for swimming goggle lenses to address the aforementioned problems. Summary of the Invention

The sliding rod moves through the inner wall of the sliding groove and extends to the outside of the sliding plate. A spring is sleeved on the sliding rod. The spring is elastically connected between the inner wall of the sliding groove and the slider. There are two automatic material picking units. The two automatic material picking units are respectively installed on two L-arms. The two automatic material picking units are symmetrically arranged. A crossbeam is fixedly connected between the linear motors in the two automatic material picking units. The linear motors in the two automatic material picking units are respectively installed on two L-arms. The gripping rings at both ends of the gripping rod are respectively engaged between each slot and the slider. The pressure sensor in each automatic material picking unit is connected to the linear motor on the same side. The sinking part is located in front of the circulating material conveying unit and is used to intermittently grab swimming goggles and harden batches of swimming goggles.

[0009] Preferably, the circulating material conveying unit includes a motor, a rotating shaft connected to the output shaft of the motor, and two supports. The rotating shaft movably passes through the supports and is rotatably connected between the two supports. A second rotating shaft is rotatably connected between the two supports. Both the first and second rotating shafts are fitted with pulleys. A transmission belt drives between the first and second rotating shafts, and a clamp is wound around the transmission belt.

[0010] Preferably, a frame is mounted on one of the brackets, a motor is mounted on the frame, a cleaner is mounted between the two brackets, a rotating shaft movably passes through the upper opening of the cleaner, and the rotating shaft is located between the inner walls of the cleaner.

[0011] Preferably, there are two limiting plates, and the two sides of the two brackets are fixedly connected by the two limiting plates. The inner wall of the transmission belt is in contact with the side of the two limiting plates that are far apart from each other. The hot air blower is installed on one of the limiting plates, and the transmission belt moves through the air outlet of the hot air blower.

[0012] Preferably, the settling section includes a vertical plate, a lifting groove is provided on one side of the vertical plate, a second motor is installed on the top of the vertical plate, a stud is connected to the output shaft of the second motor, the stud movably passes through the vertical plate and is rotatably connected between the inner wall of the lifting groove, a lifting block is slidably connected to the inner wall of the lifting groove, the lifting block is threaded onto the stud, a U-plate is installed on the lifting block, a sliding rod is movably passed through both ears of the U-plate, a clamping arm is fixedly connected to the end of the sliding rod on each ear of the U-plate, and a spring is elastically connected between each clamping arm and the ear of the U-plate adjacent to it.

[0013] Preferably, the material settling section further includes a loading and unloading arm, and both sides of the loading and unloading arm are provided with clamping grooves corresponding to the clamping arms. The loading and unloading arm is clamped between the two clamping arms through the clamping grooves. A support rod is fixedly connected to the loading and unloading arm, and a clamp is fixedly connected to the end of the support rod.

[0014] Preferably, a processing pool is provided at the bottom of the upright plate, and side frames are installed between the two supports and the outer walls of the processing pool. An upright is installed on the top of one of the side frames, and a workbench is fixedly connected to the upright. A CNC computer is installed on the workbench.

[0015] A method for using a swimming goggle lens surface hardening treatment device includes the following steps:

[0016] Step 1: Secure the swimming lens to the locking pin with the buckle clip, and attach the gripping rod to the clamp. The motor intermittently drives the rotating shaft to rotate, causing the two pulleys to move in a curved motion under the transmission belt, thereby sending the swimming lens into the cleaner for ultrafiltration cleaning.

[0017] Step 2: After cleaning, the swimming lens continues to be conveyed by the conveyor belt through the hot air outlet and dried. It then passes through the hot air and is located below the automatic material handling section. At this time, the conveyor belt continues to convey the gripper upward, causing the gripper ring at the end of the gripper to engage with the inner wall of the corresponding slot. The spring elastically resets the slider against the gripper ring for fixation. At the same time, the gripper ring is subjected to clamping force against the pressure sensor, which causes the electrical signal to start the two linear motors to move synchronously and pull the gripper rod out of the fixture.

[0018] Step 3: After being pulled out, the gripper moves horizontally towards the aligned clamp, causing the middle part of the gripper to clamp into the inner wall of the clamp. At this time, the motor works intermittently, causing the stud to drive the lifting block to descend. At the same time, the clamping arm on the U-plate drives the loading and unloading arm to descend, causing the clamp to pull the gripper down and pull it out of the slot.

[0019] Step 4: After the gripper is withdrawn, the pressure sensor loses its resistance and generates a change in electrical signal, which causes the linear motor to reset above the clamp. The first motor then intermittently transports the next gripper upward into the slot, causing the pressure sensor to generate an electrical signal again, driving the linear motor to work and transport the next gripper to the next empty clamp. This process is repeated until all clamps hold grippers. At this point, the intermittent operation of the first motor stops, while the second motor continues to work, sending the loading and unloading arm downward into the treatment tank for immersion coating to achieve surface hardening treatment of the swimming lens.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention provides a device and method for hardening the surface of swimming goggle lenses, which has the following beneficial effects:

[0022] 1. The equipment and method for hardening the surface of swimming goggles lenses adopts automated conveying. The intermittent cyclic conveying of swimming goggles is achieved through the circulating material conveying unit. The swimming goggles are sequentially sent to the cleaner for ultrafiltration cleaning, dried by a hot air blower, and then automatically conveyed to the hardening treatment process. No manual handling is required, which greatly improves the conveying efficiency. The automatic material picking unit and sinking unit between each process can realize the rapid transfer of swimming goggles between different processes, ensuring the continuity of the process, reducing waiting time, and improving the overall processing efficiency.

[0023] 2. The equipment and method for surface hardening of swimming goggles lenses adopts a feeding section design that makes batch feeding of swimming goggles more convenient. The operator only needs to fasten the swimming goggles to the locking pin with the buckle and then clamp the gripper to the fixture. No complicated operation is required. The automatic loading section and the sinking section realize the automatic loading and unloading of swimming goggles between the cleaning, sanitation and hardening treatment processes. No human intervention is required for each process for batch operation, which greatly reduces the labor burden.

[0024] 3. The equipment and method for hardening the surface of swimming goggles lenses employ ultrafiltration cleaning and air drying. Before entering the hardening process, the swimming goggles undergo ultrafiltration cleaning in a cleaner and drying in a hot air blower, ensuring that the surface of the goggles lenses is clean and free of stains. This provides a good foundation for subsequent hardening treatment and helps improve the quality of the hardening process. The CNC computer on the workbench adopts existing CNC numerical control technology, allowing the operator to automatically control the electrical equipment in the equipment, ensuring that the parameters of each process are accurate and stable, thereby guaranteeing the processing quality.

[0025] 4. The equipment and method for hardening the surface of swimming goggles lenses adopts clamps evenly distributed on the transmission belt, which facilitates the clamping and conveying of the gripping rods. At the same time, the design of the clamps also makes the fixation of the swimming goggles more stable, improving the operational stability of the equipment. The loading and unloading arms of the sinking part are clamped between the clamping arms through the clamping groove, which can be freely installed and disassembled, facilitating daily maintenance and replacement, and improving the maintainability of the equipment. The coordinated work between the components makes the cleaning, sanitation and hardening treatment processes closely connected, improving the overall flexibility of the equipment and adapting to different production needs.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1-11 This invention provides a technical solution: a device and method for hardening the surface of swimming goggles lenses, including a support 1. The support 1 is used to support and reinforce the entire device, ensuring the structural stability between the components. The circulating material conveying unit 2 is installed on the support 1 for intermittently circulating and conveying swimming goggles, and cleaning batches of swimming goggles in real time and removing water stains from the goggles. The cleaner 5 is located below the circulating material conveying unit 2, and the circulating material conveying unit 2 is located inside the cleaner 5. The limiting plate 6 is installed on the support 1, and the hot air blower 7 is installed on the limiting plate 6. The loading unit 3 is installed on the circulating material conveying unit 2 for convenient batch loading of swimming goggles. The automatic material picking unit 8 is installed on the support 1 for automatically picking up swimming goggles and circulating them between the previous and next processes. The sinking unit 10 is located on the front side of the circulating material conveying unit 2 for intermittently picking up swimming goggles and hardening batches of swimming goggles.

[0040] In this embodiment, for the purpose of conveying a batch of swimming goggles more quickly and in real time, the circulating material conveying unit 2 includes a motor 21, a rotating shaft 22 connected to the output shaft of the motor 21, two supports 1, the rotating shaft 22 movably passes through the supports 1 and is rotatably connected between the two supports 1, a rotating shaft 23 is rotatably connected between the two supports 1, pulleys 24 are fitted on both the rotating shaft 22 and the rotating shaft 23, a transmission belt 25 is connected between the rotating shaft 22 and the rotating shaft 23, clamps 26 are connected around the transmission belt 25, a number of clamps 26 are distributed at equal intervals on the transmission belt 25.

[0041] To facilitate batch loading of swimming goggles, the loading unit 3 includes a gripping rod 31. Both ends of the gripping rod 31 are engaged with a clamp 26. Four protrusions 32 are symmetrically connected to the outer wall of the gripping rod 31. Each protrusion 32 is fixedly connected with a locking pin 33, and each locking pin 33 is fastened with a buckle tab 34. The locking pin 33 is designed according to the size of the buckle tab 34, allowing it to be directly inserted into the buckle tab 34 for secure fastening. Each buckle tab 34 is fixedly connected with a swimming goggle piece 35, which is part of the swimming goggle piece assembly and is used for later insertion of elastic bands. Both ends of the gripping rod 31 are fitted with gripping rings 36, which limit the gripping rod 31 on the clamp 26 to prevent it from wobbling left and right. A frame 4 is mounted on one of the brackets 1, and a motor 21 is mounted on... On the frame 4, the cleaner 5 is installed between two brackets 1. The model of the cleaner 5 can be referred to as the WHLX-I ultrasonic cleaner. The rotating shaft 22 moves through the upper opening of the cleaner 5 and is located between the inner walls of the cleaner 5. There are two limiting plates 6. The two sides of the two brackets 1 are fixedly connected by the two limiting plates 6. The inner wall surface of the transmission belt 25 is in contact with the side of the two limiting plates 6 that are far away from each other. The limiting plates 6 improve the stability of the curved movement of the transmission belt 25 and prevent the transmission belt 25 from bending and shaking due to external forces. The hot air blower 7 is installed on one of the limiting plates 6. The model of the hot air blower 7 can be referred to as the XDND series electric heater. It is used to dry the water stains on the swimming lens 35 after cleaning. The transmission belt 25 moves through the air outlet of the hot air blower 7.

[0042] It is worth noting that L-arms are fixedly connected to the top sidewalls of both brackets 1. In order to improve the continuity between processes and enable the cleaned swimming lens 35 to be quickly placed into the hardening process, this case adopts an automatic material handling unit 8, which includes a linear motor 81. A slide plate 82 is installed on the moving end of the linear motor 81. A slot 83 is opened at the bottom of the slide plate 82. A pressure sensor 84 is embedded in the top of the inner wall of the slot 83. This pressure sensor 84 can refer to the series of sensors produced by Shenzhen Ruisite Sensor Instrument Co., Ltd. A slide groove 85 is further opened on one side of the inner wall of the slot 83. A slider 86 is attached to the inner wall of the slide groove 85. A slide rod 87 is fixedly connected to the slider 86. The slide rod 87 moves through the inner wall of the slide groove 85 and extends to the outside of the slide plate 82. A spring 88 is sleeved on the slide rod 87. The spring 88 is elastically connected between the inner wall of the slide groove 85 and the slider 86. The slider 86 and the slot 83 are close to each other on the side. The convex surfaces are symmetrical and can effectively clamp the gripper 31 in the slot and abut against the pressure sensor 84. There are two automatic material handling units 8 in this case. The two automatic material handling units 8 are respectively installed on two L-arms and are symmetrically arranged between each other. A crossbeam 9 is fixedly connected between the two linear motors 81 in the two automatic material handling units 8. The linear motors 81 in the two automatic material handling units 8 are respectively installed on two L-arms. The gripping rings 36 at both ends of the gripper 31 are respectively engaged between each slot 83 and slider 86. The position of the gripping ring 36 is aligned with the position of the slot 83 and slider 86. The clamp 26 moves between the two slide plates 82 without obstructing the movement trajectory of the clamp 26. The pressure sensor 84 in each automatic material handling unit 8 is connected to the linear motor 81 on the same side. When the pressure sensor 84 is resisted by the gripping ring 36, it will generate an electrical signal to control the linear motor 81 to work.

[0043] It is worth noting that, in order to further improve the continuity between processes, the material settling section 10 in this case includes a vertical plate 101. A lifting groove 102 is provided on one side of the vertical plate 101. A second motor 103 is installed on the top of the vertical plate 101. A stud 104 is connected to the output shaft of the second motor 103. The stud 104 movably passes through the vertical plate 101 and is rotatably connected to the inner wall of the lifting groove 102. A lifting block 105 is slidably connected to the inner wall of the lifting groove 102. The lifting block 105 is threaded onto the stud 104. A U-plate 106 is installed on the lifting block 105. The motor 103 drives the U-plate 106 to descend intermittently at equal intervals through intermittent motion. A slide rod 107 is movably inserted through both ears of the U-plate 106. A clamping arm 108 is fixedly connected to the end of the slide rod 107 on each ear of the U-plate 106. A spring 109 is elastically connected between each clamping arm 108 and the ear of the adjacent U-plate 106. The sinking part 10 also includes a loading and unloading arm 1011. Both sides of the loading and unloading arm 1011 are provided with... The clamping arm 108 has a corresponding clamping groove 1012. The loading / unloading arm 1011 is engaged between the two clamping arms 108 through the clamping groove 1012. The loading / unloading arm 1011 can be freely installed and removed through the clamping arms 108 for easy daily maintenance. A support rod 1013 is fixedly connected to the loading / unloading arm 1011. A clamp 1014 is fixedly connected to the end of the support rod 1013. There are several clamps 1014. Each time the U-plate 106 drives the loading / unloading arm 1011 to move intermittently and equidistantly, one of the clamps 1014 will inevitably align. The automatic material handling unit 8 holds a gripper 31, and a processing pool 11 is provided at the bottom of the upright plate 101. Side frames 12 are installed between the two supports 1 and the outer walls of the processing pool 11. An upright frame 13 is installed on the top of one of the side frames 12. A workbench 14 is fixedly connected to the upright frame 13. A CNC computer 15 is installed on the workbench 14. The CNC computer 15 adopts existing CNC technology, which enables the operator to automatically control the electrical equipment involved in this case, such as motor 1 21 and motor 2 103.

[0044] A method for using a swimming goggle lens surface hardening treatment device includes the following steps:

[0045] Step 1: Secure the swimming sheet 35 to the locking pin 33 by fastening the strap 34, and lock the gripping rod 31 to the clamp 26. The motor 21 drives the rotating shaft 22 to rotate intermittently, causing the two pulleys 24 to move in a curved motion under the transmission belt 25, thereby sending the swimming sheet 35 into the cleaner 5 for ultrafiltration cleaning.

[0046] Step 2: After cleaning, the swimming lens 35 continues to be conveyed by the conveyor belt 25 through the air outlet of the hot air blower 7 and dried. Then it passes through the hot air blower 7 and is located below the automatic material handling section 8. At this time, the conveyor belt 25 continues to convey the gripper 31 upward, causing the gripper ring 36 at the end of the gripper 31 to be engaged in the inner wall of the corresponding slot 83. The spring 88 elastically resets the slider 86 against the gripper ring 36 for fixation. At the same time, the gripper ring 36 is subjected to clamping force against the pressure sensor 84, which causes the electrical signal to start the two linear motors 81 to move synchronously and pull the gripper 31 out of the clamp 26.

[0047] Step 3: After being pulled out, the gripper 31 moves horizontally towards the aligned clamp 1014, causing the middle part of the gripper 31 to clamp into the inner wall of the clamp 1014. At this time, the motor 2 103 works intermittently, causing the stud 104 to drive the lifting block 105 to descend. At the same time, the clamping arm 108 on the U plate 106 drives the loading and unloading arm 1011 to descend, causing the clamp 1014 to pull the gripper 31 down to be pulled out of the slot 83.

[0048] Step 4: After the gripper 31 is withdrawn, the pressure sensor 84 loses its resistance and generates a change in electrical signal, which causes the linear motor 81 to reset above the clamp 26. The motor 21 then intermittently transports the next gripper 31 upward into the slot 83, which in turn causes the pressure sensor 84 to generate an electrical signal again, driving the linear motor 81 to work and transporting the next gripper 31 to the next empty clamp 1014. This process is repeated until all clamps 1014 hold the gripper 31. At this point, the intermittent operation of the motor 21 is stopped, and the motor 103 continues to work to send the loading and unloading arm 1011 downward into the treatment pool 11 for immersion coating, thereby achieving surface hardening treatment of the swimming lens 35.

[0049] Working principle: The operator stands on one side of the conveyor belt 25, clamps the gripper 31 onto one of the clamps 26, and then sequentially fastens the swimming lens 35 onto the clamp 26's locking pin 33 using the buckle 34. The motor 21 intermittently drives the rotating shaft 22 to rotate, causing the two pulleys 24 to move in a curved path under the transmission of the conveyor belt 25. The conveyor belt 25 conveys the clamps 26 at equal distances through the rotating shaft 22, thereby sending the swimming lens 35 sequentially into the cleaner 5 for ultrafiltration cleaning. After cleaning, the swimming lens 35 is continued to be conveyed and dried by the hot air blower 7, thus achieving an automated cleaning effect and keeping the surface of a batch of swimming lens 35 clean and free of stains.

[0050] At this point, the gripper 31 that first passes through the hot air blower 7 is located below the automatic material handling section 8. The transmission belt 25 continues to intermittently transport the gripper 31 upwards, causing the two gripping rings 36 on the gripper 31 to respectively engage with the inner walls of the corresponding slots 83. Under the elastic extension and contraction of the spring 88, the slider 86 is forced to press the gripping rings 36 and engage them in a fixed position. At the same time, the gripping rings 36 are pushed by the slider 86 and the protruding surface of the slots 83, causing the upper surface of the gripping rings 36 to press against the pressure sensor 84, thereby generating an electrical signal to control the synchronous movement of the two linear motors 81. The linear motors 81 drive the slide plate 82 to move through their moving ends, horizontally pulling the gripper 31 out of the clamp 26. After being pulled out, the gripper 31 moves horizontally towards the aligned clamp 1014, and the middle part of the gripper 31 is clamped into the clamp 1014 by the horizontal pushing force. Inside the 014 inner wall, motor 103 operates intermittently, causing stud 104 to drive lifting block 105 to descend. Simultaneously, the clamping arm 108 on U-plate 106 drives loading and unloading arm 1011 to descend, causing clamp 1014 to pull gripper 31 vertically downward, thus pulling gripper 31 out of slot 83. At this time, pressure sensor 84 loses the resistance of gripping ring 36, generating a change in electrical signal, which in turn causes linear motor 81 to reset above clamp 26. This achieves automatic loading and unloading of swimming lens 35 between cleaning, rinsing, and hardening processes, ensuring the continuity between processes. It eliminates the need for manual intervention in each process for batch operations, further reducing the burden of manpower and improving the efficiency of process transitions, thereby improving processing efficiency.

[0051] The motor 21 intermittently feeds the next gripper 31 upwards into the slot 83. Since the gripper 31 in the previous clamp 26 has already been fed, the clamp 26 can pass smoothly between the two slide plates 82 without obstruction. The new gripper 31 re-enters the slot 83 through the gripping ring 36, causing the pressure sensor 84 to generate an electrical signal again, driving the linear motor 81 to work and feed the gripper 31 into the aligned clamp 1014. The previous clamp 1014 has fed the gripper downwards at a certain distance. Since the current position of the clip 1014 is empty, it can hold a new gripper 31. Repeat the above steps until all clips 1014 hold a gripper 31. Then, stop the operation of motor 1 21 through the CNC computer 15 and start motor 2 103 to continue working to send the loading and unloading arm 1011 down into the processing pool 11 for immersion coating. Immerse the swimming lens 35 in a solution containing a hardener so that the hardener forms a thin film on the mirror surface, thereby achieving surface hardening treatment of the swimming lens 35.

[0052] After the hardening process is completed, the motor 103 reverses, thereby driving the loading and unloading arm 1011 upward away from the treatment pool 11 via the U-plate 106. The operator can easily pull each gripper 31 out of the clamp 1014 and place it on a movable shelf for recycling. Alternatively, the loading and unloading arm 1011 can be completely disassembled, and the swimming lens 35 connected to all the grippers 31 can be recycled. A new loading and unloading arm 1011 can then be replaced. The empty clamp 1014 is then re-conveyed and aligned with the automatic material handling unit 8 via the loading and unloading arm 1011, and the intermittent operation of the motor 21 and the motor 103 is started to facilitate the restart of the hardening process.

7. A method of using a swimming goggle lens surface hardening treatment device, as described in claim 6, characterized in that, Includes the following steps: Step 1: Secure the swimming lens (35) to the pin (33) by fastening the strap (34), and attach the gripping rod (31) to the clamp (26). Drive the rotating shaft (22) to rotate through the intermittent operation of the motor (21), causing the two pulleys (24) to make curved motion under the transmission of the transmission belt (25), thereby sending the swimming lens (35) into the cleaner (5) for ultrafiltration cleaning. Step 2: After cleaning, the swimming lens (35) continues to be conveyed by the conveyor belt (25) through the air outlet of the hot air blower (7) and dried. Then it passes through the hot air blower (7) and is located below the automatic material handling section (8). At this time, the conveyor belt (25) continues to convey the gripper (31) upward, causing the gripper ring (36) at the end of the gripper (31) to be inserted into the inner wall of the corresponding slot (83). The slider (86) is fixed against the gripper ring (36) by the elastic reset of the spring (88). At the same time, the gripper ring (36) is subjected to clamping force and presses against the pressure sensor (84), causing the electrical signal to start the two linear motors (81) to move synchronously and pull the gripper (31) out of the clamp (26). Step 3: After being pulled out, the gripper (31) moves horizontally towards the aligned clamp (1014), causing the middle part of the gripper (31) to clamp into the inner wall of the clamp (1014). At this time, the second motor (103) works intermittently, causing the stud (104) to drive the lifting block (105) to descend. At the same time, the clamping arm (108) on the U plate (106) drives the loading and unloading arm (1011) to descend, causing the clamp (1014) to pull the gripper (31) down from the slot (83). Step 4: After the gripper (31) is pulled out, the pressure sensor (84) loses its resistance and generates a change in electrical signal, which causes the linear motor (81) to reset above the clamp (26). The motor (21) then intermittently transports the next gripper (31) upward into the slot (83), which in turn causes the pressure sensor (84) to generate an electrical signal again to drive the linear motor (81) to work and transport the next gripper (31) to the next empty clamp (1014). This process is repeated until all clamps (1014) hold the gripper (31). At this point, the intermittent operation of the motor (21) is stopped, and the motor (103) is kept working continuously to send the loading and unloading arm (1011) downward into the treatment pool (11) for immersion coating, thereby achieving surface hardening treatment of the swimming lens (35).
