Description

Technical Field

[0001] This utility model belongs to the field of optical manufacturing and precision machining, and in particular relates to a UV curing device for optical lens processing. Background Technology

[0002] Optical lenses are the core components of optical imaging systems. Through a precisely designed combination of optical elements, they enable the focusing, transmission, and imaging of light, directly affecting image quality and application effects. Curing is a crucial step in the manufacturing process of optical lenses. Curing hardens the optical adhesive, thereby increasing its mechanical strength, which is essential for maintaining the structural integrity of the lens assembly.

[0003] However, traditional UV curing processes are usually carried out in open or semi-closed environments. In such environments, dust, fibers, and other particles in the air can easily adhere to the lens components to be cured, which not only directly affects the curing effect of the adhesive but also reduces the quality of the final product. In addition, the ultraviolet rays emitted during the curing process pose a potential hazard to human skin and eyes, and operators may face health risks if they are exposed to ultraviolet rays for a long time.

[0004] Therefore, there is a particular need for a UV curing device for optical lens processing to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional UV curing processes, which are carried out in open or semi-closed environments, such as susceptibility to contamination, unstable curing quality, and the health hazards of ultraviolet exposure to operators, this utility model provides a UV curing device for optical lens processing.

[0006] This utility model is achieved through the following technical means: a UV curing device for optical lens processing, comprising a base plate, a box body, a box door, a control panel, UV lamps, slide rails, a folding frame, a bidirectional cylinder, a placement plate, a first electromagnet, a lifting plate, a second electromagnet, a pushing component, and a sealing component. The base plate is fixed to the bottom of the box body. A rectangular discharge port is located on the left side of the box body. The box door is rotatably mounted on the front of the box body via vertically distributed hinges. The control panel is installed on the right side of the box body. Multiple UV lamps of different sizes are arranged inside the box body and electrically connected to the control panel. Two slide rails are arranged side by side at the bottom of the inner side of the box body. The folding frame is slidably disposed between the tracks of these two slide rails. The bidirectional cylinder electrically connected to the control panel is installed... At the bottom of the box, its two telescopic ends face left and right respectively, and are fixedly connected to the two sides of the lower part of the folding frame. Two other slide rails are arranged side by side and slide on the upper part of the folding frame. The lifting plate is fixed between the tops of the two slide rails. The second electromagnet is fixed on the upper part of the lifting plate, and its four edges coincide with the lifting plate when viewed from below. The first electromagnet is placed on the top of the second electromagnet. Both are electrically connected to the control panel. The placement plate is fixed on the top of the first electromagnet, and the four edges of both coincide when viewed from below. The placement surface of the placement plate has a mesh structure. The bottom surface of the first electromagnet is flush with the bottom surface of the discharge port, forming a stepless transition surface. The pushing component is set between the box and the placement plate, and the sealing component is set on the left side of the box.

[0007] As an improvement to the above solution, the pushing component includes a rack, a protective shell, a cover plate, a motor, a pulley assembly, a drive gear, and a driven gear. The rack is fixed to the rear of the placement plate, and both have the same length. The protective shell is installed at the rear of the housing. The cover plate is rotatably located at the rear of the protective shell and closes the opening of the protective shell from the rear. The motor, which is electrically connected to the control panel, is installed on the left side inside the protective shell with its output shaft facing upward. The drive gear is rotatably located on the right side of the inner top of the protective shell. The pulley assembly is located between the output shaft of the motor and the drive gear. The driven gear is rotatably located on the right side of the rear of the housing and is located behind the rack and meshes with it. It is also located directly in front of the drive gear and meshes with it. All three components have the same thickness.

[0008] As an improvement to the above solution, the sealing assembly includes a roll roller, a knob, a sealing cloth, and a weighting block. The roll roller is rotatably located inside the left side of the housing, with its two ends flush with the front and rear sides of the housing, respectively. The knob is fixed to one end of the roll roller and forms a rotational contact with the front side of the housing. One end of the sealing cloth is fixed to the outside of the roll roller, while the other end hangs naturally inside the outlet. The weighting block is fixed to the other end of the sealing cloth, with its bottom surface in contact with the bottom surface of the outlet.

[0009] As an improvement to the above solution, it also includes a locking lever and a spring. The locking lever is slidably disposed on the front left side of the box, with one end extending into the inside of the knob to form a locking engagement. The spring is sleeved on the other end of the locking lever, with its two ends fixedly connected to the locking lever and the box respectively.

[0010] As an improvement to the above solution, it also includes handles, with two handles arranged side by side and installed at the top of the base plate.

[0011] As an improvement to the above solution, a sealing gasket is provided on the side edge of the door that contacts the cabinet.

[0012] Beneficial effects: 1. By combining the closed structure of the cabinet and door with the design of multiple UV lamps, the UV curing process of the lens assembly can be completed in a completely sealed environment that isolates the outside world, effectively preventing external dust and impurities from entering, while also effectively blocking ultraviolet leakage, protecting operators from ultraviolet radiation, and improving operational safety.

[0013] By working in conjunction with the push component and the electromagnetic lock control system, the placement plate can be automatically removed and retracted when the first and second electromagnets are de-energized, eliminating the need for operators to manually reach into the box to load or unload materials, thus reducing the operational risks caused by ultraviolet exposure.

[0014] By setting up sealing components, a good sealing effect is ensured at the discharge port and the box body, further preventing ultraviolet leakage and protecting workers from ultraviolet damage.

[0015] 2. By using a combination of lever and spring, a simple and reliable locking mechanism is provided to ensure that after the sealing cloth is wound up to open the outlet, the knob can be locked to fix the roll roller, preventing the sealing cloth from being pulled by the weight of the weight block to unwind the roll roller in the opposite direction, and ensuring that the retraction process of the placement plate is carried out smoothly.

[0026] Example: A UV curing apparatus for optical lens processing, such as Figures 1-9As shown, the enclosure includes a base plate 1, a housing 2, a door 3, a control panel 4, a UV lamp 5, a slide rail 6, a folding frame 7, a two-way cylinder 8, a placement plate 9, a first electromagnet 92, a lifting plate 93, a second electromagnet 94, a pushing assembly, a sealing assembly, and a handle 21. The base plate 1 is welded to the bottom of the housing 2. A rectangular discharge port 201 is located on the left side of the housing 2. The door 3 is mounted on the front of the housing 2 via hinges distributed vertically. A hand grip groove is located on the right side of the front of the door 3. The door 3 is made of UV-resistant borosilicate glass, allowing easy access to the interior of the housing 2. A sealing gasket is provided on the side edge of the door 3 that contacts the housing 2 to ensure... The two parts fit together tightly, achieving a good sealing effect. The control panel 4 is bolted to the right side of the housing 2. Four UV lamps 5 of different sizes are all located inside the housing 2 and are electrically connected to the control panel 4. Three of the UV lamps 5 are at the same height and are bolted to the upper inner part of the housing 2 in an embedded manner. The remaining UV lamp 5 is bolted to the top inner part of the housing 2. The two slide rails 6 on the lower side are bolted to the bottom inner part of the housing 2. The folding frame 7 is slidably positioned between the tracks of the two slide rails 6 on the lower side. The bidirectional cylinder 8, which is electrically connected to the control panel 4, is bolted to the bottom inner part of the housing 2. Two telescopic ends face left and right respectively, and are fixedly connected to the left and right sides of the lower part of the folding frame 7. Two slide rails 6 on the upper side are arranged side by side and slide on the upper part of the folding frame 7. The lifting plate 93 is welded between the tops of the two slide rails 6 on the upper side. The second electromagnet 94 is bonded to the upper part of the lifting plate 93, and its four edges coincide with the lifting plate 93 when viewed from below, ensuring a stable connection between the two. The first electromagnet 92 is placed on top of the second electromagnet 94. Both are electrically connected to the control panel 4. The placement plate 9 is bonded to the top of the first electromagnet 92, and the four edges of both coincide when viewed from below, ensuring a stable connection between the two. The magnetic attraction between magnet 92 and second electromagnet 94 indirectly fixes the placement plate 9 to the lifting plate 93. The placement surface of the placement plate 9 has a mesh structure, allowing light and gas to pass through. The bottom surface of the first electromagnet 92 is flush with the bottom surface of the discharge port 201, forming a stepless transition surface. This ensures that when the placement plate 9 is withdrawn to the outside of the box 2, the first electromagnet 92 smoothly transitions from the discharge port 201. The pushing component is set between the box 2 and the placement plate 9. The sealing component is set on the left side of the box 2. Two handles 21 are arranged side by side and bolted to the top of the base plate 1. The handles 21 provide the operator with a point of leverage for the base plate 1, making it convenient to move the entire device.

[0027] like Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the pushing assembly includes a rack 91, a protective shell 10, a cover plate 101, a motor 11, a pulley assembly 12, a drive gear 13, and a driven gear 14. The rack 91 is welded to the rear of the placement plate 9, and the two have the same length. The protective shell 10 is bolted to the rear of the housing 2. The cover plate 101 is rotatably located at the rear of the protective shell 10 and closes the opening of the protective shell 10 from the rear. The cover plate 101 allows for easy access to the internal space of the protective shell 10. The motor 11, which is electrically connected to the control panel 4, is bolted to the left side of the inside of the protective shell 10, with its output shaft facing upward. The drive gear 13 is rotatably located on the right side of the inner top of the protective shell 10. The pulley assembly 12 is located between the output shaft of the motor 11 and the drive gear 13. The driven gear 14 is rotatably located on the right side of the rear of the housing 2 and is located behind the rack 91 and meshes with it. It is also located directly in front of the drive gear 13 and meshes with it. All three (i.e., the rack 91, the drive gear 13, and the driven gear 14) have the same thickness.

[0028] like Figure 1 and Figure 9 As shown, the sealing assembly includes a roll roller 15, a knob 16, a sealing cloth 17, and a weight block 18. The roll roller 15 is rotatably disposed on the inner left side of the housing 2, with its front and rear ends flush with the front and rear sides of the housing 2, respectively. The knob 16 is welded to the front end of the roll roller 15 and forms a rotational contact with the front side of the housing 2. The upper end of the sealing cloth 17 is welded to the outside of the roll roller 15, while the lower end hangs naturally inside the discharge port 201. The weight block 18 is welded to the lower end of the sealing cloth 17, with its bottom surface in contact with the bottom surface of the discharge port 201. Through the gravity of the weight block 18, the sealing cloth 17 can maintain a tight state to seal the discharge port 201.

[0029] like Figure 9 As shown, it also includes a locking rod 19 and a spring 20. The locking rod 19 is slidably disposed on the front left side of the housing 2, and its lower end extends into the inside of the knob 16 to form a locking engagement with it. The spring 20 is sleeved on the upper end of the locking rod 19, and its upper and lower ends are respectively fixedly connected to the locking rod 19 and the housing 2.

[0030] In the initial state, the folding frame 7 is in the folded state, and the bottom surface of the first electromagnet 92 is at the same horizontal level as the bottom surface of the discharge port 201. At this time, both the first electromagnet 92 and the second electromagnet 94 are energized, and the placement plate 9 is fixed on the lifting plate 93 by magnetic force.

[0031] When this device is needed for lens assembly curing, the operator first pulls the lever 19 upward to disengage it from the knob 16. As the lever 19 moves upward, the spring 20 is compressed and stores elastic potential energy. Then, the operator pinches the knob 16 and rotates the winding roller 15 clockwise to wind up the sealing cloth 17, thereby opening the outlet 201. After opening, the lever 19 is released, and the spring 20 returns to its original state, releasing elastic potential energy. This pushes the lever 19 downward to reset and re-engage with the knob 16, locking the position of the knob 16 and preventing the sealing cloth 17 from being pulled by the weight of the weight block 18 to unwind the winding roller 15 in the opposite direction.

[0032] Then, the first electromagnet 92 and the second electromagnet 94 are de-energized via the control panel 4, releasing the fixation of the placement plate 9, and the motor 11 is started. Its output shaft drives the drive gear 13 to rotate clockwise via the pulley assembly 12. The drive gear 13 meshes with the driven gear 14 in the forward direction, driving the driven gear 14 to rotate counterclockwise. The driven gear 14 meshes with the rack 91 in the forward direction, driving the rack 91 to move the placement plate 9 to the left, so that the placement plate 9 smoothly exits from the discharge port 201 to the outside of the box 2. The motor 11 is turned off in time before the driven gear 14 is about to disengage from the rack 91.

[0033] Next, place the lens assembly to be cured on the placement plate 9. After placement, start the motor 11 again and control its output shaft to drive the drive gear 13 to rotate counterclockwise through the pulley assembly 12. The drive gear 13 meshes with the driven gear 14 in the opposite direction, driving the driven gear 14 to rotate clockwise. The driven gear 14 meshes with the rack 91 in the opposite direction, driving the rack 91 to move the placement plate 9 to the right, so that the placement plate 9 smoothly returns to the inside of the box 2 from the discharge port 201. After the placement plate 9 moves to the initial position to the right, turn off the motor 11.

[0034] Then pull the lever 19 upwards again to release the knob 16 from locking, rotate the winding roller 15 counterclockwise to release the sealing cloth 17, close the discharge port 201, release the lever 19 again, and the knob 16 will be automatically locked under the action of the spring 20, ensuring that the sealing cloth 17 is tightly attached to the edge of the discharge port 201 under the gravity of the weight block 18, forming a sealed environment;

[0035] Once all preparations are complete and the housing 2 is fully sealed, the first electromagnet 92 and the second electromagnet 94 are re-energized to fix the placement plate 9 on the lifting plate 93. Then, the bidirectional cylinder 8 is activated to retract its two telescopic ends to an appropriate length, thereby pulling the lower left and right sides of the folding frame 7 inward, causing the folding frame 7 to gradually unfold. During the unfolding process, the two upper slide rails 6 drive the lifting plate 93 to rise. The lifting plate 93, through the magnetic attraction of the second electromagnet 94 and the first electromagnet 92, drives the placement plate 9 and the lens assembly on it to rise synchronously until they reach the preset height, aligning the lens assembly to be cured with the three UV lamps 5 located below. After confirming that the position is correct, all the UV lamps 5 are turned on, and the emitted ultraviolet rays irradiate the lens assembly, starting the curing process of the adhesive, which continues for a period of time to ensure full curing.

[0036] After curing, turn off all UV lamps 5, control the two telescopic ends of the bidirectional cylinder 8 to extend to the initial length, and then push the lower left and right sides of the folding frame 7 to move outward, so that the folding frame 7 gradually closes. During the closing process, the two slide rails 6 on the upper side drive the lifting plate 93 to descend. The lifting plate 93, through the magnetic attraction of the second electromagnet 94 and the first electromagnet 92, drives the placement plate 9 and the lens assembly on it to descend synchronously until the initial height is reached.

[0037] Finally, repeat the previous steps (i.e., power off, drive motor 11 to retract the placement plate 9 to the outside of the housing 2), remove the cured lens assembly from the placement plate 9, and repeat the corresponding process to retract the placement plate 9 into the housing 2 to prepare for the next curing operation.

[0038] When it is necessary to maintain or clean the inside of the enclosure 2, simply rotate the door 3 clockwise to the appropriate angle to open the enclosure 2, which is convenient for maintenance or cleaning. After maintenance or cleaning is completed, rotate the door 3 counterclockwise to the initial angle to close the enclosure 2.
