Description

Technical Field

[0001] This utility model relates to the field of optical instruments, and in particular to a UV curing device for lens bonding. Background Technology

[0002] In the field of optical instrument manufacturing, cemented lenses are widely used in various optical products such as cameras, microscopes, and laser equipment because they can overcome the imaging defects of single lenses and improve the imaging quality of optical systems. Among them, ultraviolet curing technology is one of the core processes for lens cementation. It involves irradiating the ultraviolet adhesive between the lenses with ultraviolet light, causing the adhesive to cure rapidly and form a stable adhesive layer. The rationality of the ultraviolet curing device directly determines the curing uniformity of the adhesive layer and the final surface accuracy of the lens.

[0003] In existing technologies, some UV curing devices for lens bonding use a UV light source to emit a point light source, which is then irradiated onto the lens to be bonded via a UV reflector, thus bonding the lens. However, the fixed size of the UV reflector means that it can only be used with lenses of a specific size. If the size of the UV reflector is smaller than the lens to be bonded, the UV irradiation range is insufficient to cover the lens bonding layer, which can easily lead to insufficient curing of the adhesive at the lens edge, resulting in problems such as insufficient adhesion and cracking of the bonding layer. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a UV curing device for lens bonding, thereby solving the problem mentioned in the background art where the fixed size of the UV reflector in some UV curing devices for lens bonding limits their ability to fit only lenses of specific sizes to be bonded.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a UV curing device for lens bonding, comprising: Base; Placement base, fixedly connected to the top of the base; The support frame is fixedly connected to the top of the base, located on the outside of the placement seat; The ultraviolet light source is housed within the support frame; A mounting base is disposed within a support frame. A slide rail is fixedly connected to one side of the mounting base, and a connecting frame is fixedly connected to the other side of the mounting base. A first ultraviolet reflector is fixedly connected to one side of the slide rail. A slide block is slidably connected within the slide rail, and a second ultraviolet reflector is fixedly connected to one side of the slide block. An adjusting rod is threadedly connected within the connecting frame, and a guide rod is slidably connected within the connecting frame. A connecting seat is rotatably connected to one end of the adjusting rod, and the connecting seat and the guide rod are fixedly connected. Connecting rods are rotatably connected to both sides of the connecting seat, and the connecting rods are rotatably connected to the slide block.

[0006] Optionally, a turntable is rotatably connected to the top of the placement base. The turntable has several first through holes on its surface and a second through hole on its surface outside the first through holes. Several positioning seats are slidably connected inside the placement base. The positioning seats are rotatably connected to the first through holes. A threaded sleeve is fixedly connected to the outside of the placement base. A threaded rod is threadedly connected inside the threaded sleeve. One end of the threaded rod is rotatably connected to a transmission frame. The transmission frame is slidably connected to the second through hole.

[0007] Optionally, a first fixing bolt is inserted inside the ultraviolet light source, and a second fixing bolt is inserted inside the mounting base. The first fixing bolt and the support frame, and the second fixing bolt and the support frame are both threaded connections.

[0008] Optionally, the guide rod surface is fixedly connected with a scale mark, and the scale mark corresponds one-to-one with the sum of the dimensions of the first ultraviolet reflector and the second ultraviolet reflector.

[0009] Optionally, the mounting base is inclined, and a gap is reserved between the second ultraviolet reflector and the slide rail.

[0010] Optionally, one end of the positioning seat is arc-shaped, and a protective pad is fixedly connected to one side of the positioning seat.

[0011] Optionally, a tray is fixedly connected inside the placement seat, and the tray is circular.

[0012] Optionally, an anti-slip pad is fixedly connected to the bottom of the base, and the bottom of the anti-slip pad is provided with anti-slip texture.

[0013] The beneficial effects of this utility model are as follows: by rotating the adjusting rod, it can be moved along the connecting frame. In conjunction with the connecting seat, guide rod, connecting rod, slide seat and slide rail, the overall size of the ultraviolet reflector composed of the first ultraviolet reflector and the second ultraviolet reflector can be adjusted. This allows the ultraviolet light irradiation range to be adjusted according to the size of the lens to be bonded, ensuring that the ultraviolet light can cover the lens and expanding the applicability of the device. Place the lens to be bonded into the placement seat, then rotate the threaded rod. With the help of the threaded sleeve, transmission frame and turntable, the positioning seat can slide along the inner wall of the placement seat so that the center of the lens to be bonded coincides with the center of the placement seat. This avoids problems such as uneven UV irradiation and misalignment of the bonding layer during subsequent bonding due to the lens to be bonded being misaligned, thus providing a preliminary guarantee for the accuracy of lens bonding. The first and second fixing bolts allow for the disassembly and assembly of the ultraviolet light source and the mounting base, facilitating maintenance of these components and enabling replacement of components based on the specific condition of the lens to be bonded, thus further enhancing the practicality of the device.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figure 1 and Figure 2This utility model provides a technical solution: a base 1, a placement seat 2 fixedly connected to the top of the base 1, a support frame 3 fixedly connected to the top of the base 1 outside the placement seat 2, an ultraviolet light source 4 disposed inside the support frame 3, a mounting seat 5 disposed inside the support frame 3, a slide rail 501 fixedly connected to one side of the mounting seat 5, a connecting frame 502 fixedly connected to the other side of the mounting seat 5, a first ultraviolet reflector 503 fixedly connected to one side of the slide rail 501, a slide block 504 slidably connected inside the slide rail 501, a second ultraviolet reflector 505 fixedly connected to one side of the slide block 504, an adjusting rod 506 threadedly connected inside the connecting frame 502, a guide rod 507 slidably connected inside the connecting frame 502, a connecting seat 508 rotatably connected to one end of the adjusting rod 506, a fixed connection between the connecting seat 508 and the guide rod 507, and connecting rods 509 rotatably connected to both sides of the connecting seat 508, with the connecting rods 509 rotatably connected to the slide block 504.

[0017] Rotating the adjusting rod 506 causes it to move along the connecting frame 502. During this process, the connecting seat 508, constrained by the guide rod 507, will move in a direction perpendicular to the mounting seat 5, thereby driving the connecting rod 509 to rotate around its connection point and causing the slide block 504 connected to one end of the connecting rod 509 to slide along the slide rail 501. This, in turn, causes the second ultraviolet reflector 505 to move in the same direction, thus adjusting the overall size of the ultraviolet reflector composed of the first ultraviolet reflector 503 and the second ultraviolet reflector 505. This allows the ultraviolet irradiation range to be adjusted according to the size of the lens to be bonded, ensuring that the ultraviolet light can cover the lens and expanding the applicability of the device. When the ultraviolet light source 4 is activated, the point light source emitted by the ultraviolet light source 4 is reflected by the first ultraviolet reflector 503 and the second ultraviolet reflector 505 and then shines on the lens to be glued, which is placed in the placement seat 2, so that the lens can be glued.

[0018] Furthermore, a scale mark 5071 is fixedly connected to the surface of the guide rod 507, and the scale mark 5071 corresponds one-to-one with the sum of the dimensions of the first ultraviolet reflector 503 and the second ultraviolet reflector 505.

[0019] By observing the scale on the guide rod 507, the operator can intuitively and quickly know the overall size of the ultraviolet reflector composed of the first ultraviolet reflector 503 and the second ultraviolet reflector 505, thereby improving the accuracy of adjustment.

[0020] Furthermore, the mounting base 5 is tilted, and a gap is reserved between the second ultraviolet reflector 505 and the slide rail 501.

[0021] The mounting base 5 is tilted to ensure that the ultraviolet light, after being reflected by the first ultraviolet reflector 503 and the second ultraviolet reflector 505, can illuminate the lens to be bonded; a gap is reserved between the second ultraviolet reflector 505 and the slide rail 501 to prevent the second ultraviolet reflector 505 from rubbing against the slide rail 501 during the adjustment process.

[0022] Optionally, an anti-slip pad 101 is fixedly connected to the bottom of the base 1, and the bottom of the anti-slip pad 101 is provided with anti-slip texture.

[0023] The anti-slip pad 101 increases the friction between the device and the surface on which it is placed, thereby improving the stability of the device during use.

[0024] Please see Figures 1 to 4 The present invention provides a technical solution: a turntable 201 is rotatably connected to the top of the placement base 2, a plurality of first through holes 2011 are opened on the surface of the turntable 201, a second through hole 2012 is opened on the surface of the turntable 201 outside the first through holes 2011, a plurality of positioning seats 202 are slidably connected inside the placement base 2, the positioning seats 202 are rotatably connected to the first through holes 2011, a threaded sleeve 203 is fixedly connected to the outside of the placement base 2, a threaded rod 204 is threadedly connected inside the threaded sleeve 203, a transmission frame 205 is rotatably connected to one end of the threaded rod 204, and the transmission frame 205 is slidably connected to the second through hole 2012.

[0025] The lens to be bonded is placed in the placement seat 2. Then, the threaded rod 204 is rotated to move along the threaded sleeve 203, thereby driving the transmission frame 205 connected to one end of the threaded rod 204 to slide along the second through hole 2012 on the surface of the turntable 201 and drive the turntable 201 to rotate at the top of the placement seat 2. Then, through the first through hole 2011 on the surface of the turntable 201, the positioning seat 202 is driven to slide along the inner wall of the placement seat 2, so that the center of the lens to be bonded coincides with the center of the placement seat 2. This avoids problems such as uneven ultraviolet light irradiation and misalignment of the bonding layer during subsequent bonding due to the offset of the lens to be bonded, and provides a preliminary guarantee for the accuracy of lens bonding.

[0026] Furthermore, one end of the positioning seat 202 is arc-shaped, and a protective pad 2021 is fixedly connected to one side of the positioning seat 202.

[0027] The positioning seat 202 has an arc-shaped end, which allows it to fit the lens to be bonded more closely. Together with the protective pad 2021, it can prevent the hard surface of the positioning seat 202 from scratching the surface of the lens to be bonded and causing damage, and can also prevent the lens to be bonded from deforming due to excessive clamping force.

[0028] Furthermore, a tray 206 is fixedly connected inside the placement base 2, and the tray 206 is circular.

[0029] The support plate 206 provides additional support for the lens to be glued.

[0030] Please see Figure 1 and Figure 2 The present invention provides a technical solution: a first fixing bolt 401 is inserted inside the ultraviolet light source 4, and a second fixing bolt 510 is inserted inside the mounting base 5. The first fixing bolt 401 and the support frame 3, and the second fixing bolt 510 and the support frame 3 are both threaded connections.

[0031] The ultraviolet light source 4 and the mounting base 5 can be disassembled and assembled using the first fixing bolt 401 and the second fixing bolt 510. This not only facilitates the maintenance of the above-mentioned components, but also allows the components to be replaced according to the specific situation of the lens to be bonded, further improving the practicality of the device.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
