Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing technology, and in particular to curing devices and dispensing machines. Background Technology

[0002] During the lens manufacturing process, glue is used to seal the lens or to adhere and fix the lens element to the lens barrel. After the glue is applied, a UV lamp is used to cure the glue.

[0003] Currently, most UV curing processes for lenses involve batch baking in ovens. For example, application number CN214347661U, entitled "UV Adhesive Curing Oven," includes a cabinet with a tray inside. The tray supports lenses assembled using UV adhesive. The oven also contains a UV lamp assembly. The UV lamp beads of the UV lamp assembly emit ultraviolet light that irradiates the UV adhesive on the lens, causing the UV adhesive to cure.

[0004] However, current UV adhesive curing ovens are not suitable for automated production lines, resulting in low efficiency and problems with UV curing quality. The method of batch baking lenses in an oven requires placing the lenses after dispensing into a tray before putting the tray into the UV adhesive curing oven for irradiation and curing. Due to the time difference in the dispensing process, some of the adhesive on the lenses that were dispensed first may cure prematurely, affecting the quality of subsequent UV curing.

[0044] like Figures 2 to 4 As shown, the curing device 100 provided in this embodiment includes a support cylinder 1, a rotating assembly 2, a clamping cylinder 3, and a UV lamp assembly 4. The support cylinder 1 is used to receive the workpiece. The rotating assembly 2 is disposed between the support cylinder 1 and the clamping cylinder 3. The rotating assembly 2 includes a rotary motor 21, a first clamping cylinder 22, and a second clamping cylinder 23. The first clamping cylinder 22 and the second clamping cylinder 23 are installed at the output end of the rotary motor 21. The rotary motor 21 is used to drive the first clamping cylinder 22 and the second clamping cylinder 23 to rotate around a vertical line, so that one of the first clamping cylinder 22 and the second clamping cylinder 23 faces the support cylinder 1, and the other of the first clamping cylinder 22 and the second clamping cylinder 23 faces the clamping cylinder 3. The UV lamp assembly 4 is disposed on one side of the clamping cylinder 3 and is used to irradiate the workpiece located on the clamping cylinder 3.

[0045] Specifically, the curing device 100 is located on one side of the conveying device 200. After the dispensing device 300 dispenses adhesive onto the workpiece, the conveying device 200 transports the workpiece to the carrier cylinder 1. The rotary motor 21 drives the first gripper cylinder 22 towards the carrier cylinder 1, clamping the workpiece on the carrier cylinder 1. Simultaneously, the second gripper cylinder 23 faces the clamping cylinder 3, clamping the workpiece on the clamping cylinder 3. The rotary motor 21 then drives the first gripper cylinder 22 and the second gripper cylinder 23 to rotate 180°, so that the second gripper cylinder 23 faces the carrier cylinder 1 and places the cured workpiece on the carrier cylinder 1, facilitating the transfer of the workpiece by the conveying device 200. The first gripper cylinder 22 faces the clamping cylinder 3 and places the uncured workpiece on the clamping cylinder 3, facilitating the UV lamp assembly 4 to irradiate and cure the workpiece. Optimizing the structural layout of the curing device 100 makes it suitable for automated production lines, improving curing efficiency and quality, and ensuring production efficiency.

[0046] In this embodiment, the workpiece is a lens; in other embodiments, the workpiece may be a lens barrel or other components.

[0047] Optionally, the top of the bearing cylinder 1 is provided with a sink trough, which is used to hold the workpiece and prevent the workpiece from falling to the ground or the table of the equipment.

[0048] Optionally, the rotating assembly 2 also includes a lifting cylinder 24. A rotary motor 21 is mounted on the output end of the lifting cylinder 24. The lifting cylinder 24 drives the rotary motor 21, the first gripper cylinder 22, and the second gripper cylinder 23 to move up and down in the vertical direction. After the first gripper cylinder 22 and / or the second gripper cylinder 23 clamps the workpiece, the lifting cylinder 24 drives the rotary motor 21, the first gripper cylinder 22, and the second gripper cylinder 23 to rise in the vertical direction, so that the workpiece leaves the sink of the bearing cylinder 1 or leaves the gripper of the clamping cylinder 3. When it is necessary to lower the workpiece, the lifting cylinder 24 drives the rotary motor 21, the first gripper cylinder 22, and the second gripper cylinder 23 to descend in the vertical direction.

[0049] In this embodiment, there are three carrier cylinders 1, which are spaced apart along the X-axis; the output end of the rotary motor 21 is equipped with three first gripper cylinders 22 and three second gripper cylinders 23, which correspond one-to-one; there are three clamping cylinders 3, and three sets of UV lamp assemblies 4, which correspond one-to-one.

[0050] To improve production efficiency, the dispensing device 300 dispenses adhesive to three workpieces at a time. The conveying device 200 simultaneously transports the three workpieces to one side of the curing device 100. The three workpieces are placed one-to-one on the three carrier cylinders 1. The three first gripper cylinders 22 correspond one-to-one with the three carrier cylinders 1, and the three second gripper cylinders 23 correspond one-to-one with the three clamping cylinders 3. After the workpieces on the three carrier cylinders 1 and the three clamping cylinders 3 are clamped, the rotary motor 21 drives the three first gripper cylinders 22 and the three second gripper cylinders 23 to rotate 180° to exchange positions. The cured workpieces are placed on the carrier cylinders 1, and the uncured workpieces are placed on the clamping cylinders 3.

[0051] Optionally, the UV lamp assembly 4 includes a support plate 41, a lifting cylinder 42, a mounting base 43, heat dissipation fins 44, and a UV lamp 45. The support plate 41 is disposed on one side of the clamping cylinder 3; the lifting cylinder 42 is mounted on the support plate 41; the mounting base 43 is slidably mounted on the support plate 41 in the vertical direction and connected to the output end of the lifting cylinder 42. The lifting cylinder 42 is used to drive the mounting base 43 to move closer to or away from the workpiece located on the clamping cylinder 3 in the vertical direction; the heat dissipation fins 44 are mounted on the mounting base 43; and the UV lamp 45 is mounted on the side of the heat dissipation fins 44 facing the lifting cylinder 42.

[0052] After the workpiece is placed in the clamping cylinder 3, the lifting cylinder 42 drives the UV lamp 45 to approach the workpiece, increasing the irradiation intensity and accelerating the curing speed of the adhesive. At the same time, the heat dissipation fins 44 dissipate heat to prevent the UV lamp 45 from burning the workpiece. After the workpiece has cured, the lifting cylinder 42 drives the UV lamp 45 away from the workpiece so that the first gripper cylinder 22 or the second gripper cylinder 23 can transfer the workpiece.

[0053] Optionally, the UV lamp assembly 4 also includes a fan 46, which is rotatably mounted on the mounting base 43 about a horizontal line. In this embodiment, the fan 46 is used to accelerate heat dissipation. By rotatably mounting the fan 46 on the mounting base 43 about a horizontal line, the fan 46 is prevented from blowing hot air directly onto the workpiece.

[0054] Optionally, the UV lamp assembly 4 also includes a first connector 47 and a second connector 48. The first connector 47 is threaded onto the mounting base 43, and the second connector 48 is fixedly connected to the output end of the lifting cylinder 42. One of the first connector 47 and the second connector 48 is provided with a snap-fit ​​groove, and the other of the two is provided with a snap-fit ​​part, which snaps into the snap-fit ​​groove.

[0055] The outer wall of the first connector 47 is provided with external threads, and the mounting base 43 is provided with threaded holes. Rotating the first connector 47 causes the first connector 47 to be inserted into the threaded hole of the mounting base 43. The depth of the first connector 47 inserted into the threaded hole is not easy to determine. Therefore, the first connector 47 and the second connector 48 are set as a floating connection. The snap-fit ​​part can rotate at a preset angle in the snap-fit ​​groove to use the first connector 47 for installation on the mounting base 43.

[0056] Optionally, a nut is fitted around the periphery of the first connector 47.

[0057] Optionally, the UV lamp assembly 4 also includes a limiting post 49 and a buffer 410. The buffer 410 is fixedly installed on the support plate 41, and the limiting post 49 is fixedly installed on the mounting base 43. The limiting post 49 and the buffer 410 are aligned in the vertical direction.

[0058] like Figure 1 As shown, this embodiment also provides a dispensing machine, which includes a conveying device 200, a dispensing device 300, and two sets of curing devices 100 as described above. The dispensing device 300 and the two sets of curing devices 100 are arranged sequentially and spaced apart on one side of the conveying device 200 along the X-axis direction.

[0059] The dispensing speed of the dispensing device 300 to the workpiece is faster than the curing speed of the curing device 100 to the workpiece. Therefore, in this embodiment, two sets of curing devices 100 are matched with one dispensing device 300.

[0060] Optionally, a vision inspection device 400 is provided at the end of the conveying device 200. The vision inspection device 400 can inspect the appearance of the workpiece to identify the quality of the dispensing.

[0061] In this embodiment, the dispensing device 300 includes three dispensing components, and the conveying device 200 includes nine conveying gripper cylinders. All nine conveying gripper cylinders are mounted on the moving module. In the clamping state, the three conveying gripper cylinders at the front end correspond one-to-one with the three dispensing components, the three conveying gripper cylinders in the middle correspond one-to-one with the three carrier cylinders 1 of the upstream curing device 100, and the three conveying gripper cylinders at the rear end correspond one-to-one with the three carrier cylinders 1 of the downstream curing device 100. In the conveying state, the three conveying gripper cylinders at the front end correspond one-to-one with the three carrier cylinders 1 of the upstream curing device 100, and the three conveying gripper cylinders in the middle correspond one-to-one with the three carrier cylinders 1 of the downstream curing device 100.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
